Solve : Trojan and/or Virus Capabilities??? |
|
Answer» Hello all.......can anyone tell me if a Trojan or any type of virus can send explicit emails from a computer to (what appears to be) random explicit ads or EMAIL addresses? Can said virus also copy previously typed words and phrases from the individual that owns the computer and use this in the text of messages? For example, computer operator writes an email to a friend and says, "hey, I'll be in Chicago today...come visit!" Then the same verbiage in that message, or other messages, ends up in a REPLY to some explicit listing on a social site or ten. Can this be true or am I being lied to by someone that is actually sending these out and trying to cover up with a virus scare? I could use a little advice from someone who understands viruses.....thanks! peoples e-mail accounts can be hackedYou're being lied to... You're being lied to... Now what luck of the irish is saying is also partly true. Email accounts can be hacked and the hacker can take an email that was sent to joe shmoe 3 weeks ago and RESEND it but that is KINDA it. Yes a hacker can install a key logger or some clear text that is imbedded. The hackers when they hack a email account can spam people from your email account and mass email also but that is it. On your email accounts regularly changing your security questions, having a very complex password, do not use the same password that you do for your PC or other email etc. Now should you be careful yes, can you get your PC infected by an email attachment yes etc etc. But just like a diet you must pay attention and be careful what you do Remember there is a lot of BS out there. Hopefully this helps, Mike |

Solve : Old website problem, please advise.? |

Answer» I'm on the web ministry TEAM for Trinity Baptist Church in Lebanon Oregon. If you use Google and search for "trinity baptist church, lebanon oregon" the very first site that shows in the search results is www.lebanonfellowship.com. This is our old website, launched by a former pastor. All attempts to contact him (across the country) for the information we need have failed. We're making a new site for our church, but we want to get rid of this one. We don't know who hosts it, we don't have any admin log in information. Not to MENTION it doesn't have the correct information on it for the community. How can we get rid of this site? Or at least make sure our new site is listed above the defunct one? Please be kind if I didn't use the correct lingo Thanks to any who read this. Good evening This is all I was able to find by reversing the name Reverse Whois: "Montana Real Estate" owns about15 other domains Registrar History: 1 registrar NS History: 4 changes on 3 unique name servers over 3 years.

If you do not have any hosting information or LOGIN information for the old site, than it is, effectively, not your site. The frequency of a site updating is CONSIDERED rather strongly, so if yours is updated semi-regularly it will not take long to outrank the old one anyway. |

Solve : How to check your DNS? |
|
Answer» How to check your DNS. DNS means Domain Name Server. A DNS changer is bad program that changes your DNS so that you are taken to bad web sites. Because this problem is so widespread, some people are going to lose internet service in a few days from now. At the Windows command prompt just type ipconfig /all Here is an page that gives more detail of how to do it. (Wim/Mac/Linux) How to find the DNS settings Then change it to one of these: Public DNS Server List (Updated June 2012) Or ask you local provider what the right IP is for DNS in your area.Then is an ip changer a bad program?Quote from myself: Quote A DNS changer is bad program ...DNS is used to convert a domain name into a form that if piratical for the internet. The DNS must provide right IP to connect to a web SITE. Historic EXAMPLE: Users want to use Google to find something. The bad program, the DNS Changer, directs the bequest to another we site, a fake Google site that has ADVERTISING different from the Google advertising. The bad guys make quick money from the ads on the fake site. Some of the ads are even part scams and other kinds of stuff that breaks the law and cheats people. That has really happened. Some news sources have led people to believe it was not a serous issue. It was very serious. True, only a small number of people got hurt. Yet those who were hurt, were hurt. It is like when the Weather Report says 'Only 5 people were killed in the STORM'. Here is the background information you should read. If you haven't. (PDF) DNSChanger Malware If the FBI did not take strong action, many would have been subject to all kinds of bad stuff. Quote from: TheWaffle on July 16, 2012, 03:48:29 PM Then is an ip changer a bad program? Domain Name System (DNS) is a database system that translates a computer's fully qualified domain name into an IP address. Networked computers use IP addresses to locate and connect to each other, but IP addresses can be difficult for people to remember. For example, on the web, DNS allows you to connect to another networked computer or remote service by using its user-friendly domain name rather than its numerical IP address. Conversely, Reverse DNS (rDNS) translates an IP address into a domain name. i don't think it's a bad program.. |

Solve : Does installing Windows 7 interfere with the motherboard bios settings? |
|
Answer» HI. I'm just wondering if Windows 7 has altered my MOTHERBOARD's bios? I'm asking this because I have a Asus P5e3 WS Pro motherboard, which can only support Windows operating system up to Vista. I didn't know this when I INSTALLED Windows 7 onto it. Fed up with getting the blue screen error, when trying to reinstall Windows XP on it again, I zero WIPED the drives, and reformatted them again. But even so I'm still getting the same blue error screen when I attempt to reinstall Windows XP again. So I'm wondering if when I installed Windows 7, that it wrote something to the motherboard's bios to prevent any future system downgrading.An OS cannot and will not write/change anything in the BIOS... I run Win7 on a P5 ASUS MBoard with zero issues...Vista on the 2nd HDD. Post the entire BSOD including the gibberish... Did you happen to make any changes to the BIOS ? ?Not sure where that info came from...all the documentation i read mentions nothing about it not being ABLE to run Win7. It would be silly for a MBoard manuf to limit the board to OS's. |

Solve : Is Windows 8 for Tablet PCs only?? |
|
Answer» Sorry guys, but I cannot find a good answer on Google so I post the question here. No. Quote from: BC_Programmer on October 28, 2012, 03:30:54 AM No. That is a very good answer indeed. Geek Hoodlum's Google must be broken, because if I search on "Windows 8 DESKTOP laptop" (desktops and laptops are not tablets) I GET "About 402,000,000 results", and if I type "Windows 8 Wikipedia" I see "Windows 8 - Wikipedia, the free encyclopedia" at the top of the results, and halfway down the page it says this: Hardware requirements PCs (Bla bla bla) Tablets and convertibles (Bla bla bla) ...which kind of suggests that Windows 8 is not for tablets only. Also I have seen lots of ads offering Windows 8 upgrades for PCs (not laptops) RUNNING Windows 7. The tablet version of Win 8 which they dubbed "RT" for whatever reason holds quite a few differences than the PC version.... Biggest one that stands out to me is the fact the Tablet version will NOT run any 3rd party software....only apps from the MS store. Depending on which tablet device you have you may not be able to run the full version... More Info... The Full version as stated above is for PC's...both Desktops and Laptops...This one of the best detailed explanation of O/S Win 8 and it RANGE of functionality directly related to the device it is used upon that i have come across. http://www.cbc.ca/news/technology/story/2012/10/25/f-windows-eight-launch-nowak.html truenorthThanks for the inputs guys! |

Solve : how to find the balance between not trying, and being creepy.? |
|
Answer» In high school i wouldn't try to get girls, and so people blamed me that i didnt have a gf because i didnt take the initiative. I asked a few people and they said its creepy to just randomly talk to girls. They are right. Talking to girls in real life is one thing, random girls on the web is different. More stalkerish. In most areas of our lives it's good to try to keep things simple, but in meeting a new person, simply saying "hi!" is one of the worst things you can do, unless the person is about to leave and that's all you have time to say in order to get the person's attention. It's always better to include something more in your first hello, preferably something relevant to what's going on around you, rather than saying something personal about yourself or the other person. Instead of "Hi! My name is ___" or "You look [pretty]", it's better to comment on your surroundings, and you can often leave out the word "hi". For example, with summer coming up in the northern hemisphere and casual outdoor concerts a common place for seeing a person you'd like to talk to, while waiting for the event to begin, it's better to say something like "Are you here to see Act A or Act B?" or "I'm familiar with Act B but not Act A." Being less personal is less invasive. I'm from New York City, and 3 part repartee with strangers happens all the time. One person says something, the other person says something back, and the first person responds to that without the expectation that further conversation will ensue. It gives both people the opportunity take a moment to decide if further interaction feels welcome, and relieves the tension of having an internal debate of "Should I say something?/Should I not?". You've given it a shot, so there's no need to kick yourself after for having not tried. Again, you comment on what's around you, and probably not the other person. If you go somewhere and see someone you know only minimally, that's when the word "hi!" is useful, but still include something more because they might not recognize you out of your usual context. As for the internet, I think you have to include something relevant to what about the person caught your attention, but more than just "I think you're good looking". Why is just saying "hi" so creepy? I don't know. Maybe it's because anyone can say it, whereas including something more takes more intelligence or more social skills and people who are better able to communicate are regarded as more emotionally stable. Your a guy so you know what most guys are like... right? Well girls know what most guys are like also. So put it like this. If some guy on fb or where ever out of the blue started saying hi to you it would be what? Cool or creepy? Hi there Quote from: reddevilggg on October 04, 2012, 06:40:11 AM Hi there That will be the title of the Made for TV movie I described above. See. Brilliant. Also that inset picture only like it was taken from "The Scorpion King". It totally wasn't. That's just from the scene where we have to go into my pet robot's AI to find the water chip for the vault before the Stargate explodes. |

Solve : Weather Channel App (Causing PC to slow)? |
|
Answer» This was a pretty cool app; but since I put it on my PC it became slower. Another thought occurred to me after my initial response. If this weather app is important to you when you install it disable it as part of the "start" menu and that may eliminate the problem it is creating re slowing down the computer.truenorth I, too was having problems and narrowed it down to the Weather Channel App. I use to have it running all the time at start up and then when I shut it down it would tell me something was running in the BACKGROUND. My computer was sluggish and I disabled the WC app and haven't had any problems since. There were also intermittent things that were happening that I have noticed don't happen any more. KEEP in mind you can visit www.weather.com anytime with your browser and get the weather. You COULD also visit the site, enter your zip code, and then save that page as a bookmark. If you save it a bookmarks toolbar on your browser, you'll have that bookmark always in view at the top of your browser; you won't need to open the drop down bookmarks menu to find it. I use weatherunderground...I deleted the app and it seemed to fix things.That app used to be detected as malware by most anti-malware programs though I'm not sure if that's STILL the case. In any case, yeah I'd say scrap it due to its history of not respecting user's machines. |

Solve : Data Storage Question with uncontrolled temperature/humidity extremes? |
|
Answer» Anyone know of the best way to store data for safe/secure keep, where temperature and humidity could\would be an issue. I have a bunch of data that I dont want on some online storage location ( taxes, financial documents, inventions, etc ), but yet an onsite backup isnt good enough if for example if my home burned down etc. I have been using DVD's to store this data, but I noticed that the disc's after 4 years in the trunk of my car are showing signs that humidity is eating them away at the outside edge where the the aluminum is sandwiched between the 2 plastic layers and there is a grey/black corrosion happening. Since the data starts on the inner track and works its way out towards the edge as the capacity of the disk is used during the burn process, I am guessing that if I burned say just 4GB of the 4.7GB capacity that I could just rotate this set with a new clone of these disc's every so many years, and the .7GB space would be area that I expect to errode from humidity etc. As for flash drives, Heat and cold don't cause electricity to flow so I don't see how they could be responsible for loss of data on a flash drive. The colder the better, to avoid charge leakage, but let's be realistic here! From a Texas Instruments data sheet for MSP430 flash memory: http://www.ti.com/lit/an/slaa334a/slaa334a.pdf (I had to embed the Arrhenius EQUATION as an image) Quote Data Retention Time and... Quote Further tests show the exact number of years at 25°C is 1324 years. I'm unsure of the statistics but a stolen car or an unfortunate car accident may be just as (I would think a house fire would be the lesser) likely as a house fire. Keep it in your home = Climate controlled... SentrySafe Fire-Resistant, Waterproof Key Lock Safe Quote The safe accommodates standard size hanging file folders (not included) and is rated for a 1/2-hour fire protection for items such as CDs, DVDs and USB drives up to 1550-degreess Fahrenheit.Thanks for all the info everyone. REALLY cool info that Salmon posted! And learned something new about flash memory storage over time in relation to temperature with a leakage factor that increases loss of data over time as the gate charge signature of 1 or 0 is lost. Very Cool! Given that at the outset your query seemed to be opening a discussion as to how to prevent or minimize the affects of high temperature and humidity on data storage media currently available. So setting aside the various merits of certain types of storage media let us just deal with the temperature/humidity issue. By itself humidity issues can be lessened greatly by including in a suitable sealed container the media and a liberal amount of silica gel (it is a fantastic drying/moisture absorbing material). However it does nothing re temperatures. If one were to want to preserve data but need not access it on a frequent basis then both temperature variances and humidity fluctuations are for the most part eliminated by burying the container (plastic would be a good choice as it seems to never deteriorate) to a depth of between 8 and 10 feet where the temperature is essentially constant (about 50f). So dependent on your access to appropriate real estate that might only require some physical excursion and little monetary outlay. Your desired interval of access will determine how your underground containment should be constructed. Given your presumed concerns i take it you live in such conditions to cause you issues. In my opinion the are few worse places you could be offsetting your concerns than in the trunk of an automobile as your storage location.I suppose an oven might be worse.truenorth |

Solve : Desktop randomly shuts off? |
|
Answer» Man, its been forever since i've been here, and I come back with another issue! I have a desktop that randomly shuts off on its own. No BSOD just black. It will run every now and then for extended periods, and then BAM, shutdown. The power supply was recently replaced to get the thing so it would even turn on anymore. I dont know what all Info I need to GIVE but here's a short list. No BSOD just black.Does it mean here that the monitor is only black and the tower is still running? Have you checked your hardware temps. lately and cleaned out some dust from the inside? Any problem in safemode? Download Speccy and then install the program. To post and publish a SNAPSHOT of your PC. . In the Menu BAR, click File -> Publish Snapshot . Click Yes > then Copy to Clipboard . On your next reply, right-click on a empty space and click Paste on reply box then click Post. Tower and all turns off. The computer isnt hot at all either. We've even sprayed out all the dust with compressed air. Our roomate wiped the OS off the system, and it wont go through the XP setup, it wont stay on long enough to run it.I have seen power supplies go bad and cause this issue. Do you have a spare power supply to install into it to test if this fixes it? For this type of issue you have to verify: - All Fans are spinning. ( The system will shutdown if monitored fan(s) report no movement ) - Nothing is running too hot ( Thermal paste missing or OLD dry and chalky between say CPU and HEATSINK ) - If Power Supply is Healthy. |

Solve : What android phone is the best in your opinion?? |
|
Answer» I'm thinking about getting an android phone when I renew my contract with Verizon in July. What android phone do you PREFER and why?I currently have SAMSUNG Galaxy S 3. In my opinion it is the best android phone on the market. From personal experience I can say that it is AMAZING and the screen is crisp and very smooth.Good morning potter and welcome to CH I am with "Joseph Chambers" I like the Galaxy S2 and S3. The OS is great, screen is very clear and reception is 2nd to none. The OS runs very fast and smooth. Hope this helps, Mike Nobody can tell you what is the "best" anything. You have to decide that for yourself. I can tell you that I have the Razr Maxx and am DELIGHTED with it.I've had HTC for the last few years and can't fault them. Give them a try.I should totally pull a Kanye and say that the iPhone 5 is the best phone of all time, but the S3 is a decent phone. Although it is quite dim and the battery life isn't all that amazing, it is a good overall phone.I use an HTC One XL and I'm totally in love with the thing. Apart from having the best coverage/antenna in Australia when I bought it, my other reasons for buying were the 'big' screen and good quality images, and the interface really resonated well with me more so than any other Android unit. |

Solve : Converting to MJEG? |
|
Answer» Just bought a new wide screen TV that has a USB built into the side for USE with a flash drive. I'm able to view Pics but the only video format it supports is Motion Jpeg. I have DOWNLOADED a few converters (Wondershare Ultimate Video Converter, AVS Video Converter, ffdshow Video Converter), but even though they claim to convert to Motion Jpeg, there isn't an option for it in the directory. Is there any program that SOMEONE can sugest that actually converts to Motion Jpeg? |

Solve : Storing Passwords etc.? |
|
Answer» I visit SEVERAL forums which requires me to use a password trouble is most of my passwords are not the same for obvious reasons so at the moment they are written down in a note book , where would the best place to be on my computer where i could store them for EASY access....I am running Windows 7 if THATS any help.....probably simples ..Much appreciated.http://lastpass.com/Thanks for the speedy reply,rather than having to download a programme would rather store them in a file or document or something where i could view them by entering a single password if that is at all possible or somewhere secure. ???Cheers.If you've never used a password manager (and I'm guessing you haven't), I SUGGEST you give lastpass a try. At it's most basic level it will store your passwords and enter them for you when you visit the various sites, but it offers many more features you'll find interesting and attractive. And it's free.Here's ANOTHER free one, old but still works on all Windows OS. |

Solve : Time for a new OS, reborn? |

Answer» Hi! Due to the obvious risk of being locked I will keep this attempt nice.it's probably going to get locked anyway. Quote MS Excel is the best program Microsoft has ever designed (I mean that).Subjective. Excel is mostly useless to me, personally. My vote would go to Visual Studio. Quote But newer versions are simply too and unneccesarily complicated (I use a vintage version, i.e 97).People said the exact same thing about Excel 97 compared to Excel 5.0. My point is that some people are resistant to change but unaware of it, so they come up with ad hoc justifications for their pre-existing biasses. I'm not super-fond of the ribbon, myself, but recognizing that I am more against the change itself rather than the result of that change helps. Quote Most people don't need all the features that today comes with a program.Very true. Quote My point is that new programs, more often than not, are larger and thereby consumes unneccesary CPU power.demonstratably false. Larger programs to not consume more CPU. Additionally, This ignores the issue that unused CPU cycles are wasted cycles anyway; if a program uses 50% CPU and completes half as fast as if it used all the available capability, what good has it achieved, other than wasting time? OS thread scheduling could be used to make processes low-priority so that they never take cycles away from other processes. My point being that it is silly to have some idea that unused CPU cycles contribute positively to performance, because they don't, for obvious reasons. Quote My vision is that applications should be scaled down to a minimum when we buy them. If we then want additional featutres, like f.i 100 fonts & sizes instead of only one, then we could simply buy it. Module for module.The installations do provide options to enable and disable various features of the application. One such feature includes Installing the features only when they are used. Quote But we do not need all these features by default. And it slows down the processor...Again, the former is why options are provided during installation. The latter is demonstratably false; code that doesn't execute does not effect overall execution speed. Quote One more benefit with my vintage version is that it can do log-log plots. Which I haven't found in later versions (2003).XY Scatter chart, select desired sub-chart type, and change both axes to log. Plots are now found as part of the chart Module (and yes, it quite literally is a separate component, exactly the type of functionality you suggested!), because they both are a graphical representation of data. Quote This is either because I suck at windows or that the program has been adapted to economics (with bar-grahs and other useless stuff).Fact is that while you consider it useless, a lot of other people probably don't. They don't just add these features willy-nilly- they add them through user feedback and testing. A good example of this is that they found a lot (vast majority) of people using Excel for lists of data- more like a database. So they changed features to better suit that workflow, even though arguably it could have been said to be beyond the scope of the program. I often see people use Excel as a database too... Quote My vision is to be able to speed things up while keeping the amazing and simple concept of single-cored processors intact and at the same time keep the visual or audial experince nice.But at what point is a single-cored processor no longer a singler-cored processor? It could be argued that the original Pentium's SuperScalar architecture and dual pipelines offered simultaneous execution of instructions, so isn't it effectively the same concept? Quote Multiple-cored processors will not solve the problem in the long run.What problem? Quote Neither will sci-fi quantum-computers or the like do (probably).There is no way to know how post-von nuemann machines will work. Quote Because what should we do later on when all programs has mutated to even larger ones? Use 100 cores?This is a typical debate strategy (and fallacy) which basically takes the oppositions concept and inflates it to ridiculous proportions. The fact of the matter is that multiple cores and parallel processing are the future simply because we cannot make a single core go much faster. We've reached the clock speed limit; therefore the hardware industry is moving forward by multiplying the number of cores. This is not really a new thing, either; servers have had multiple processors for quite a long time (mid 90's at least) for the reason that they are handling a lot of different tasks simultaneously and so multiple processors and/or cores are better than the approximation of concurrency used for a single processors, which have a high OVERHEAD in terms of context switches. Quote We should use the resolution that is NEEDED for the specific application. And not generally "good to have, I can compress it later".using your later example: let's say you took a photo exactly for what you needed on the web. so it came out 640x480. That serves your need. But what if later you decide "hmm, that would make a pretty cool poster". You're screwed- all you have is 640x480. You can't make a poster out of it, and you can't take the picture again for obvious reasons. You've essentially fenced off what you are able to do with the image by virtue of deciding that you will never need to do X with it, without understanding at the time that needs and requirements change. Quote In the long run, precompressing by f.i directly use 8-bit audio instead of 16-bit (read that this automaticly gives an addional 30 times in compression compared to MP3)No it doesn't. using 8-bits per sample instead of 16-bits per sample is going to reduce size exactly by half for obvious reasons. And it sounds much worse. Quote But if we refrain from designing bigger and bigger programs, my solution will hold and everyone will get their resolution, quality and speed they want.At the time. But if the needs for that data change, they're screwed. Not a very future proof scenario, but since you advocate the use of architecture-dependent assembly language this lack of foresight comes as no small surprise. Quote It is interesting to note that camera manufacturers compete with number of pixels. There's lots more to fotographing than resolution. I f.i bought a camera recently. It had some 8 MPIX. But I only wanted to upload the pictures to fb and other chat forums like yours. I finallly found a feature which could compress the pictures from default 3,5MB to some 130kB. I was happy there for a while but I realized that I wanted the camera to take the pictures with the low resolution by default. Guess what? It was not possible!I don't know what camera you have (well, that's a lie, you have a Coolpix S6150) but every single digital camera I've used has had a feature built in that let's you change the resolution. Unfortunately on at least one occasion I switched it to 1024x768 and forgot afterwards to increase the resolution, which effectively ruined a few images. (you can't get 1024x768 images developed). If I had "forgotten" the other direction, though, creating the appropriate sized image would be a matter of resizing the larger one. Making an image smaller is easier than trying to make it larger, because it doesn't try to create data where there is none. (This is also one of the reasons that the "digital enhancement" stuff shown on TV is ludicruous- more than once I've seen a show have "security footage" of a perp or something where the face was maybe 8 pixels, and they basically say "enhance" and the program has somehow managed to create millions of other pixels pretty much out of thin air. Quote But if I wanted to manufacture a (very) large photo to hang on my wall then yes, higher resolution is (for fun) needed. The issue here is that you are assuming that, at the point of capture, a person is going to know every single possible usage for a recording or image. They won't. Also: regarding the image, What exactly are we looking at there? All I see is a few IC chassis with some resistors, capacitors, and LEDs attached. Also, what progress has been made since Sept 22nd, when the picture was taken? Are they integrated into some more functional unit? I imagine they are supposed to be plugged into the various IC bases that are part of the "motherboard/test board" unit whose image you posted earlier, taken in June?I shoulda left this locked...rogerk8, You don't have a multiple core processor do you? Or you haven't ever loaded it fully. A single core CPU that is fully loaded will stop responding but a multi core CPU will allow you to access the OS and fix things, such as killing the process that is taking all of a CPU core. Multiple CPU cores allow better usefulness. Science can do more processing on multiple cores. You can run [email protected] on your multlple cores while doing other things - or human protein folding, or other distributed computing projects. Just one other point - programs with more options don't necessarily slow down a CPU, they use more RAM. Hi! How do I reply to this amazing and educational input? How much am I not learning just by expressing my crazy thoughts? With regard to the argument for 8-bit audio for DRASTICLY increasing CPU speed, I confess that that was stupid! But dual cores is also stupid. This is because it only increases speed twice and that probably is a happy(!) estimation (please correct me if I'm wrong). Because I suck at windows I do not understand how to make such nice quotes like you do, so this will have to do: My statement : "Because what should we do later on when all programs has mutated to even larger ones? Use 100 cores?" Your reply: "This is a typical debate strategy (and fallacy) which basically takes the oppositions concept and inflates it to ridiculous proportions. The fact of the matter is that multiple cores and parallel processing are the future simply because we cannot make a single core go much faster.

I still think that this is the wrong approach for the future. Multiple cored processors will not solve our future need for faster and faster computers (which "incompetent" software companies, no name, will indirectly require). This is simply exactly because of what you say with "We've reached the clock speed limit". And I say "we can't use 100 cores in the same space. We must reduce the amount of unneccesary data chewed by our poor processors". I know I sound like a dinasour, but I mean well I also know, I'm getting boring but let's consider this: My friend (the one I "hated" for a while) got in contact with a friend in the USA. His friend asked him what type of computer he had. My friend said a Mac running at 30MHz. His friend said, well that's prehistoric! But yet he could still keep in contact with his friend. One more thing, did his computer take 100 times longer to start than mine? Guess what, no! I'm sorry, but I keep on insisting that the programming can be made to be much more efficient than today. One final example: Today my beloved collegue and friend fixed a computer password problem. It ran Windows 7. It had a processor of 2,2 GHz and 2GB of RAM. Turning on the computer took a while but not that irritating. Logging in took however over a minute! Clicking around yielded the (actually quite nice) new type of timeglas (a rotating circle). And whatever we did yielded that same timeglas. Wait, wait, wait, that is. Windows... Is this the future? I hope not! One more and final thing (I promise): With regard to photographing I understand your point. And I have learned. I discussed it with my friend today. I almost (obs) immediatelly understood that if you take a picture of pure resolution you can not increase the resolution afterwards. So this version of my point might not be so good. Unless you only want to use it in smartphones or for uploading to nice chatrooms like this. I.e bragging about how good you are I thank you all for replying so nicely to my topic. I saw at work today that there was an answer but I was actually afraid to read the answer...I love beer! With regards to your final fun comment BC, here are the facts: I am actually that much of a drunk that I tremble so much that I can't solder my CPLD to the arrived Schmartboard. So I am trying desperatelly to make one of my collegues to do it for me. I have tried for a month now but nothing happens. It is not so strange either, because who wants to stay after work just to help a friend (well, I would). But nothing happens. So I'm getting more and more frustrated (again). Who should I begin to "hate" this time? Best regards, Roger PS Attaching the architecture of my CPU. [year+ old attachment deleted by admin] Quote from: rogerk8 on October 19, 2012, 05:44:25 PM But dual cores is also stupid. This is because it only increases speed twice and that probably is a happy(!) estimation (please correct me if I'm wrong).This is not the way to think about it. Multiple Cores don't increase speed by a direct factor of the multiple of cores anymore than the Dual pipeline architecture of the original Pentium doubled it's speed. I already explained why Dual and more cores are helpful speed wise: the fact is that at this point, the large set of processes running on a machine (and even for individual programs, which often can benefit from doing multiple things simultaneously) started to require almost as much overhead in terms of context switching between processes (eg. concurrency being used to emulate asynchronous execution). There were basically two ways to solve that issue, which involve either cranking up the clock speed (which is only possible to a certain point, and clock speed is hardly an indicator of anything anymore, given the fact that a Celeron processor is usually clocked about twice the speed of processors with FAR better performance. The other was to add multiple core dies to the same processor. This would alleviate the context switches (since for each X added core you reduce the number of context switches X-fold). Quote Because I suck at windows I do not understand how to make such nice quotes like you do, so this will have to do:To paraphrase Charles Babbage- "I cannot rightly apprehend the confusion of ideas that would lead to this statement"... Quoting on this forum has nothing to do with Windows... Quote I still think that this is the wrong approach for the future. Multiple cored processors will not solve our future need for faster and faster computersTwo problem with this involve the fact that you assert essentially to have an inside track to the knowledge of exactly what our future needs will be for faster computers; Otherwise, how would you know that parallelism was not a solution to those as of yet unseen issues? Quote (which "incompetent" software companies, no name, will indirectly require).This expresses a complete misunderstanding of how the software industry works, in general- a completely understandable one, mind-you, but the best way to see would be to go back to the original 8088. Naturally, we had 8088 programs, written (usually) in x86 assembly. Intel, of course, has released far more chips after the x86. the 80186 doesn't count (not being in consumer machines) but the 286 introduced new instructions and a new execution mode. These new features were not "required" by the software of the time, and at first a 286 system really just performed like a faster 8088. But eventually, programmers started to move towards the new platform, and use the new features of the architecture. This had two repurcussions: first, the programs written in assembly essentially had to be rewritten. Even though the 286 and 386 had very similar cycle-eaters, it added at least one new one (the data alignment cycle eater) that meant that a lot of hand-tuned Assembly written for the 8086/8088 Processors, while performing faster on the 286 or 386 (because of reduced wait states and an overall improved architecture) had to be rewritten for maximum performance on them. Most of them never got rewritten, simply because it wasn't worth the effort. On the other hand, Once compilers (such as the C compiler) were UPDATED to use new instructions, those programs simply needed to be recompiled to take advantage of the new processor features. This is particularly the case starting around the Pentium, when new Instruction sets were designed more around their use by a compiler than by their use by a programmer working in assembly. (And the number of rules about speed, cycle eaters and the various instructions raised exponentially both because of change to a superscalar architecture (Pentium) as well as simply because they were so different from their predecessors. When the 386 came around, it "finished" protected mode- the exploitation and use of which in a program required a rewrite almost entirely, since it used a completely different memory addressing scheme; Additionally, it had it's own gotcha's that either made 8088 assembly optimizations pointless (for example, using a byte-sized values in preference to word-sized ones on a 8088 was a common optimization because of it's 8-bit external data bus, but this advantage completely disappeared with the 286 (which was 16-bit through and through) as well as the 386 (which was 32-bit through and through, the 386SX notwithstanding). the 8-bit bus cycle eater (which ate cycles by virtue of limiting the bus size to 8-bits). One might reasonably think that with the 386 and the 286, that cycle eater went away, particularly since the 8088 prefetch queue cycle eater is a side-effect of that 8-bit bus, as well as the fact that the 286 and 386 have larger prefetch queues than the 8088 (6 bytes for the 286 and 16-bytes for the 386), and can perform memory access and instruction fetches in fewer cycles. But it doesn't, for several reasons. For one thing, instructions that branch will still empty the prefetch queue, so instruction fetching slows down after most branches. When the queue is empty, it doesn't really matter how big it is. (Branching on these processor should be avoided anyway, on account of it taking second cycles apiece). Anyway, as we went through new hardware, the software evolved to take advantage of it. Hardware was not pushed forward by software; hardware just inexorably marched forward, and software companies came along for the ride. For example, the much chagrined release of Vista brought with it a collosal change in the form of the desktop OS actually exploiting the capabilities of the graphics card available on most modern systems. Most people thought this was silly, but the point is that at an XP desktop, the graphics card is basically sitting there. Some people spend hundreds of dollars on a graphics card, so having it do the same job that a 12 dollar special GPU could do seems rather silly. Sure, they could play... Quake 3 or whatever and do timedemos, but outside games, you don't even see that expensive hardware. Same for memory; many PCs had 1GB or 2GB of memory (at least); XP didn't use it. It almost always sat unused. So Vista added a memory disk cache (SuperFetch) that used that memory to increase performance. Quote This is simply exactly because of what you say with "We've reached the clock speed limit". And I say "we can't use 100 cores in the same space. We must reduce the amount of unneccesary data chewed by our poor processors". I know I sound like a dinasour, but I mean wellI think what you might be confusing here, is that for example- If you run Vista on a 1GB machine with a dual core 2.33Ghz it might boot in say... bah... maybe 25 seconds? I dunno. But if you put, say, Windows 95 on it, it boots in mere seconds. So one might surmise that the Windows 95 machine is actually making better use of the hardware. But it is fact it's underutilization of the machines capabilities that make it appear fast. it uses only a small portion of the available memory, CPU capabilities (both in terms of clock speed as well as instruction sets) and so forth; the result is that you are not really running Windows 95 on a new Intel i7 (or what-have you) but what is effectively a really-really fast Pentium Anyway, for the future, since software follows hardware, there is no reason to think that software requirements will somehow march past the capabilities of the hardware This is why parallelism is the software future: since the only way to go forward hardware wise is with multiple cores (due to the quantum tunnelling issue) software is going to follow. Quote My friend (the one I "hated" for a while) got in contact with a friend in the USA. His friend asked him what type of computer he had. My friend said a Mac running at 30MHz. His friend said, well that's prehistoric! But yet he could still keep in contact with his friend. One more thing, did his computer take 100 times longer to start than mine? Guess what, no!Oh, good. a Friend of a friend story. a Mac SE can be used for browsing, but it is definitely not fast at it. It also makes the same mistake as above. Of course, most older machines can be used for modern purposes, if you are willing to use older software and wait a bit longer. For example, I'm sure there are IRC clients available on systems such as that Mac that work perfectly fine. However, At the same time, I doubt there is a 3d-modelling tool comparable to the current versions of 3ds max in terms of capabilities. So it depends entirely on what somebody wants to do. Most of the systems people are buying today are far overpowered for what they will be used for (web browsing and E-mail) so the effect is that with that many overpowered machines, software has marched forward so that web browsing and E-mail has taken advantage of that otherwise untapped power. Quote I'm sorry, but I keep on insisting that the programming can be made to be much more efficient than today.However, you've yet to provide anything other than anecdotal evidence toward that cause. Quote Today my beloved collegue and friend fixed a computer password problem. It ran Windows 7. It had a processor of 2,2 GHz and 2GB of RAM.likely confirmation bias. (same story, IMO, with all the 'terribleness" of Windows ME). Quote With regard to photographing I understand your point. And I have learned. I discussed it with my friend today. I almost (obs) immediatelly understood that if you take a picture of pure resolution you can not increase the resolution afterwards.Actually today graphics artists are more arguing amongst themselves about whether to use 32-bits-per-pixel at all; the debate now is whether it is worth it to go to 128 bits per pixel (with each colour component being a full 32-bits). This is of course completely silly as far as making graphic images for websites or programs is concerned. However, where it get's relevant is when dealing with hard-copy print and magazines, since smooth gradients can occasionally have clear "lines" on them as a result of the lower colour resolution (paired with the colour conversion to CMYK for print). naturally, of course, This is a feature only used by print artists, but consider for a moment that a lot of print artists get their subjects from a digital camera, and one could make the case for digital cameras to even have the ability to capture that amount of information. (In fact, most graphic artists that employ digital photography have digital apparatus that costs several thousand dollars with advanced capabilities such as that, simply because it is something that such a person is going to need for their work.

Best regards, Roger PS Attaching a picture of another passionate interest of mine [year+ old attachment deleted by admin]You seem to like LEDS! if thats your passion. Why are you making your analog electronics modular with those IC thru hole component sockets. I have only seen these used many years ago when using different "analog" modes. Also lots of time soldering the LEDS to the correct polarity when they make LED bar arrays which are better and more professional looking for a final product such as linked: http://www.mouser.com/ProductDetail/Lumex/SSA-LXB10IGW-GF/?qs=sGAEpiMZZMvnlkTg8UMATwn7m4RH1JwofoFCSpZH5AY%3dHi! Thank you DaveLembke! The problem with your nice solution is that I am using standard 16-pin DIL sockets. I use 16-pin to be able to display one byte (or two nibbles actually) at the same time. The LED-arrays you so kindly suggested are however of 10 "bits" per module. It do therefore not fit so nicely as my hand-soldered "byte"-arrays does. It was however nice to see that you were actually able to choose color on the array. If you had special 30-pin sockets, that is. Thank you! Now I turn to BC. Here are my thoughts and questions after once again having read all your nice inputs: 1) What is context switches? 2) What is cycle-eaters? 3) What is superscalar architecture (Pentium)? 4) Pentium, 32-bit wide address AND data bus? 5) Pentium I = fastest single core available (100MHz)? 6) Vista, a good example? 7) What is SuperFetch? Hardware pushing software forward. Is this really true? 9) 32-bits times RGB = 96-bits and not 128? 10) CMYK? 11) SS-Drives and lower speed at the bus destroys my point! (even though SSDs are capacitively small and expensive) 12) With "automaticly generated code" I think they are using predefined functions with lots of available parameters while only using a very few each time (please correct me if I'm wrong). 13) There is no line b, should be before beep, yes? 14) I am beginning to love C :-) 15) I suck at computers :-) The ones that have followed my topic know that I mean no harm. I just want faster computers. And I can't see why we can't have them today already. I mean that the hardware is fully developed, but the software sucks. It might however be the other way around, but I will not signe under that. I mean that the (single core) processors are fast enough. And we need to think about program size (how fun is it to see a program load?) and file size (what is the real use for 24-bit picture resolution?). I further more offer a speed-increase of (only) twice for 8-bit audio files (in your smartphone of which you can't hear the difference in you poor iPhone standard ear-phones). Consider this: Your smartphone/iPad screen is as large as perhaps 4" times 4". This means 10000 mm, roughly. If you appreciate fast downloading and reallly don't care how you see the actual pictures, then you migth have 10000 pixels or one per mm^2 ). This is a rough picture but it downloads fast...) While each pixel (in practice) has to be 3 bytes (one per color, RGB) you will now have a picture of only 30kB. Which will load very fast. Considering a "bad" connection of 1M bit/s, this will only take approximatelly 1s (but modern connections are way better than that). If you are a real speed-freek, you may even tell your operator that you want them in back & white only. Hightening the speed 3 times more! Because let's face it, don't we want the higher resolution at home (only)? So what does it matter then that our portable machines don't have the highest resolution? I for one loves speed. And maybe to be able to select that, the one I want to enlarge and put on the wall, Often you can ask your friend to resend it in higher color resolution... I know this is kind of silly, but I do think I have some kind of point here. Another crazy example: My friend at work told me he had bought an actual functional phone for not more than 10 bucks! (poor chinese people...). It was a Samsung and you could both text and make phonecalls with it(!) And it had a stand-by time of over two weeks. Two weeks!! Consider then these new and "neccesary" smartphones. How long is their stand-by time? 2 DAYS?! And how much more useful are they, actually? Aren't they just more fun? Because they are for sure not that much more useful (I don't care about "useless" apps). Finally here is an IRRELEVANT example: The first tube amp I ever built (Williamson 2X6W pure Class A) let me play as load so that the neighbours came knocking. This was before I reached the fantastic sound-level that began to distort (in that nice way only tube amps can). Consider also that most of us play at not much more than "noon" at the volume knob. This means that the output power is actually "maximum output power" DIVIDED by 10. So if you have an amp of say 2X50W, you do not play much more than 2X5W while you are having your party (in your appartment). Yet, this is a high sound level, is it not? Conclusion: You do not need all this power or resolution! Take care you all! Best regards, Roger Quote from: rogerk8 on October 22, 2012, 02:15:37 PM Here are my thoughts and questions after once again having read all your nice inputs:OK! I'll go through each one Quote 1) What is context switches?As you know, Operating Systems for the last decade or so have had some method of multi-tasking. Today, this is done with threads. Threads are managed by the OS Kernel. A Context switch is basically when the OS goes from one thread, puts it on "hold" and starts executing another thread. With multiple cores, there are fewer context switches because more threads can be run simultaneously. For example, let's pretend we had 16 threads. With a single core machine, that means that there are going to be 16 context switches to go through all the threads of execution. With two cores, however, 8 threads could be on one, and 8 on the other, meaning that there will only be half as many context switches (A context switch only occuring when the context of execution of a given core changes (eg. when the scheduler switches out the stack frame and heap between two threads on the same core). Quote 2) What is cycle-eaters?"Cycle eater" is a term used by assembly programmers when referring to instructions, or sequences of instructions, that take more time than one would normally expect. This is normally a result of other parts of the system contributing to a delayed execution time of the given instructions. The term "cycle-eater" here is from Michael Abrash's book, "Graphics Programming Black Book" which focuses on the use of Assembly Language for direct programming of the hardware in DOS: Directly from an early chapter: Quote I call these cycle-eaters because, like the monsters in a bad 50s horror movie, By example, some of the major cycle eaters of the 8088 are it's 8-bit external data bus, it's prefetch queue, Dynamic RAM refresh, and Wait states. The thing about these cycle eaters is that they aren't really documented; however, it's worth realizing that the people writing Compilers are well-versed in assembly language, and therefore are almost always aware of these cycle eaters. In fact, in addition to changing the instructions being used, choosing different target processors usually means different output to account for the various cycle-eaters present on different processors. Quote 3) What is superscalar architecture (Pentium)?A "SuperScalar" Processor implements a form of instruction-level parallelism. It's basically a sort of "multiple core" processor, but each functional unit is not a separate core but an execution resource inside the single CPU; such as the ALU, bit shifter, multiplier, etc. Basically they will often execute more than one instruction during a single clock cycle by simultaneously dispatching multiple instructions to redundant functional units on the processor. One might wonder what this has to do with assembly language: well, using instructions carefully a good assembly programmer might be able to interleave instructions to try to maximize the number of instructions run concurrently. (A Compiler, on the other hand, will be able to do that...) Quote 4) Pentium, 32-bit wide address AND data bus?iirc Original Pentium has a 32-bit wide internal bus and address bus, and a 64-bit external data bus. Quote 5) Pentium I = fastest single core available (100MHz)?No. I went with the Pentium processor because it is the first with a Superscalar architecture, which is still a single core but is practically two 486 processors on a single die; (referred to as the U pipe and the V pipe) with the second one being stripped down. Since the discussion more or less revolves around multiple cores, and the purpose of multiple cores is simultaneous execution, I was establishing the fact that processors were using simultaneous execution long before we had multiple cores in consumer machines. Quote 6) Vista, a good example?Not sure I follow. A good example of what? Most of the speed issues with Vista were a result of manufacturers loading the machines down with crapware, and not because Vista required hardware that exceeded what was available at the time. What exceeded the hardware capabilities was Vista plus a few hundred useless pieces of crapware, which is quite a different Ostrich egg. Quote What is SuperFetch?Windows Vista and 7 cache commonly used files on the disk in unused areas of System Memory that would otherwise be idle. Basically, it's a disk cache. The effect is a noticable speed improvement, which is more pronounced with more Memory. (One of the big advantages being that people with Gobs of memory no longer have it sitting idle when they aren't playing Skyrim). Quote Hardware pushing software forward. Is this really true?Yes. That's why I said it. Intel/ AMD release hardware with new capabilities. Software cannot be written to take advantage of those new capabilities until the processor is released or at least documented, so it's a bit difficult to try to follow the idea that software is driving hardware forward to any sort of conclusion. Quote 9) 32-bits times RGB = 96-bits and not 128?32 bits of Red, Green, Blue, And Alpha. are 128 bits. Quote 10) CMYK?Cyan, Magenta, Yellow, and blacK. used for printing. Printers use pigments and not light so they use Cyan, Magenta, and Yellow as primary colours. Quote 12) With "automaticly generated code" I think they are using predefined functions with lots of available parameters while only using a very few each time (please correct me if I'm wrong).Ironically, this sort of thing is far more common in Assembly via Macros. Quote 13) There is no line b, should be before beep, yes?I'm not sure what you are referring to, though I do remember providing a "beep" function of sorts in Assembly and C. Can't seem to find it but I recall posting it, so I think that is what you are referring to. The bug, for what it's worth, was that the Assembly version beeped one too many times. Hi! What is Alpha? Intensity, or? I thought only RGB was needed. It seems that I know less about computers than I thought. And this kind of explains it all. I do however still think that: 1) We do not need all the features a program nowadays provide (this will just make it load/start more slow than neccesary) 2) We do not need the hysterical resolution that nowadays are common (but the long-term use is hard to predict...) 3) I am not certain anymore but it seems like we could write more code-effective programs (using single cores and assembly) 4) Multiple cores are not the future in the long run (because there's a limit on how many cores you can actually use) 5) Maybe the problem (read slow computers) isn't the high-level language. Maybe the problem is badly designed compilers. I know I am being stubborn but this is what I think. My next generation of CPU (using a FPGA instead of a CPLD) I think will have a 32-bit wide address bus and 16-bit wide data bus. But if I fail at this (or maybe both) I would like to buy a similar CPU on the (second hand) market. What kind of CPU should I look for? 486? It doesn't matter if both the address bus and the data bus is 32-bit wide. But I kind of like the asymmetry because this is how my first CPU will work (if I ever get it to work, that is). Finally, you have taught me that assembly do not work so well with multiple cores. So that is another reason why I stick to my belief. I think I have said all I wanted to say. Take care! Best regards, Roger PS Attaching the schematic of my CPU. And yes, the other one above was more of a block-diagram than a picture of the actual architecture. Because I'm so bad at computers but at same time very interested (especially in hardware), could you please recommend a book I should read? It need perhaps not be for dummies but approximatelly at that level. I am very interested in hardware protocols (like the formatting of an hard drive f.i) and the way a (modern) computer actually work. All hardware considered.

[year+ old attachment deleted by admin] Quote from: rogerk8 on October 24, 2012, 01:37:18 PM What is Alpha? Intensity, or? I thought only RGB was needed.Per-pixel blending. Essentially translucency. For photo's it's not typically used, but it's used heavily in graphics for blending. Obviously, once the image is "complete" it is merged into a single layer and depending on use-case it will probably be 24-bit or 32-bit. If it's for the web usually it get's optimized to an 8-bit palette. Big issue being that 8-bit palette means one-bit Alpha (essentially a transparency mask). Quote 1) We do not need all the features a program nowadays provide (this will just make it load/start more slow than neccesary)It does not increase load or start times. in and of itself. Quote We do not need the hysterical resolution that nowadays are common (but the long-term use is hard to predict...) That depends. New laptops are coming out with resolutions as high as 2560x1440/ In order to take advantage of this extra fidelity, raster images are going to have to be larger and have a greater resolution, or Scalable graphics will need to be used. The later can be more processor intensive than the former at a cost of transfer size. Quote 3) I am not certain anymore but it seems like we could write more code-effective programs (using single cores and assembly)I already explained this. I'm not sure if I should bother to explain it again, but I will- saying there is a major divide between single core and multi-core machines is fallacious: again, the first Pentium was essentially two 486 processors. Why does having those two execution units in a single core suddenly change it? The processor needs special attention by assembly programmers (and compiler writers) for performance improvements, in particular taking advantage of dual execution pipes. If you are saying that my statements about the Pentium's dual execution pipes means single core processors are "better" to use, than you are mistaken since the Pentium processor is a single core processor. Quote 4) Multiple cores are not the future in the long run (because there's a limit on how many cores you can actually use)There is only such a limit using imperative programming. Functional Programming as well as languages like Erlang that discard the current ideas about concurrent programming techniques (such as threads) and instead favour the functional style of immutable data structures as well as a different concurrency concept; which can either be in the form of tasks, coroutines, or "processes". These languages will automatically take advantage of as many cores as exist on the machine, and are heavily used for large server machines with 64-cores as well as distributed computing models. Quote 5) Maybe the problem (read slow computers) isn't the high-level language. Maybe the problem is badly designed compilers.part of the problem is people with a similar idea to you that think they "know better" than the compiler writers and essentially write Assembly in a high-level language. The result is that their code is even slower... so they blame the compiler, even though they took steps to subvert it. Another important point with regards to this is- let's go with the assumption that Assembly is indeed more efficient overall than other High Level Languages. Therefore, we can declare that the current end products are not as efficient as possible. So we allegedly should be taking efforts to make them more efficient. Even following this logic there are several fallacies. The best example would be a analogy. Let's go with cars since that is so popular in Computing analogies. The same could very well be said of car manufacturers- They use Steel,Plastic, and Aluminium... but I mean, wouldn't cars be better and more efficient if they were made out of Tungsten? They would, indisputably. The metal has a very high melting point so it would essentially be heat resistant, and it's practically indestructible. But building cars out of tungsten is fundamentally a bad idea. First, Tungsten is not cheap, and it takes longer and is more expensive to machine. Second, we have the problem that in a car accident the tungsten metal could become a cage that traps victims; the "jaws of life" tool that firefighters use to get into wrecked cars would be garbage, since the tungsten would be pretty much indestructible. So there is an overall safety issue. Of course the answer is for people to "not crash their cars" but that is obviously not a realistic Expectation. Accidents happen. Additionally, All these extra costs would all just be passed on to the consumer. The same would be true of a modern application being written in Assembly language. The development costs would be exorbinantly higher than even using a language like C, for very little gain; and the consumer would be the one to bear the brunt of the costs. A Triple-A game such as skyrim costs around 60 dollars today, and took maybe 5-6 years to develop. If the entire thing was written in Assembly, it would be in development for maybe three times as long, cost 6 times as much, and the speed improvement wouldn't matter because in 6 years even the cheapest possible machine would be able to run it on the highest settings. It's also worth remembering that early on, when games to be written in Assembly to be performant, they cost much the same as they do now. The Advantage that high-level languages have provided is to make larger projects more managable. Compare the Second Ultima (which cost I believe over 100$) to Skyrim. Skyrim is indisputable a more complex project overall, but the fact is that the complexity is managed well with higher-level languages and modular design. Ultima II was written in Assembly, but is plagued with problems- first the programmer used a large variety of undocumented "hacks" to the PC platform that modern system either discard entirely and emulators cannot emulate. The end result is that The game cannot even be made playable on a modern machine. That is, While the game was finicky at the time, it's now essentially useless without hardware from that era. A Program that doesn't run at all cannot be proclaimed efficient- and that isn't to even account for the constant divide errors one get's because the game wasn't designed to run on today's faster computers. Basically the entire argument falls apart- Assembly language was fine when the resulting program was only going to be one on a specific type of machine whose various specifications were well known (such as the PDP-11) but today, the variety of hardware available and it's different capabilities mean that any assumption is basically invalidating future portability. It doesn't matter how fast or efficient a program is if you cannot run it at all. Quote If it isn't you Mr G, then it's got to be you Mr B! I don't know who Mr G is, and I don't know who Mr.B is. My last name starts with B but then again if you did even the most basic research (eg. my blog->main website->Name on bottom footer) you could easily find out my full name and reach the conclusion that I am neither of these people who you have conjectured me to be. Hi! Could someone please explain Alpha in laymen terms. I do not understand english so well. But as far as I understand, RGB is enough. And I can't understand why it isn't always enough. As usual it is always interesting to read your marvellous input, BC. And yes, I had already looked at your fantastic blog. Guess what? I did not understand a single thing This is simply because I suck at programming languages.

[year+ old attachment deleted by admin] Quote from: rogerk8 on October 25, 2012, 04:17:28 PM Could someone please explain Alpha in laymen terms. I do not understand english so well. But as far as I understand, RGB is enough. And I can't understand why it isn't always enough. Alpha is transparency. This is important in graphics use, especially on the internet, where the graphics artist can specify certain parts of the image as a mixture of red, green, and blue plus a transparency amount. 0 = transparent, 255 = opaque. If you have a square of red (#FF0000) plus alpha (80, 50%) this results in a pinkish square on a white background, but on a blue background it will look more purple. Essentially, alpha is a technique used for color blending. Another use is thus: because images are always rectangular, a circle requires the circle itself, but the outside must be either a solid color, or transparent, which will allow the image to be used seamlessly on any color background.Thank you, Technogeek! I still think I do not understand this. But I can appreciate the difficulties for color to appear correctly at different backgrounds. And this might not be as simple as ordinary RGB-blending (yielding all the rainbow colors). But I have never heard of this before. It amazes me! And that fascinates me. Because a CRT did not have a "forth" cannon. It was only RGB. In short this means that one pixel do not only need three bytes (256 levels for each color) it also needs a fourth byte (the Alpha-byte), yes? And this is always embedded in ordinary pictures, or? So you have to calculate with four bytes per pixel? Is this true? Best regards, Roger |

Solve : Sharing my Fireproof "Data Safe" Project? |
|
Answer» Figured I'd share this in case anyone else decides to make one of these. I wasn't satisfied with having to open and close one of these to add new data, so I decided to mount a 500GB External Hard drive into mine and drill 2 x 1/2" holes in the side of the safe to allow for USB Cable and power cord to pass thru to the drive that is MOUNTED snug inside of it. Used concrete bit to punch thru it. It drilled through quickly as for the cement that this safe is made from is almost like hard packed sand and soft to drill. What is not shown in this is that I will be going to the hobby store to pick up modeling clay that is the type that you can fire or bake to harden or leave to dry to harden. I am going to pack that clay into this hole with cables to plug the hole and KEEP it fireproof for the drive inside. Also to mention that the safe I picked up for 50 CENTS more is waterproof with a rubber gasket that seals when closed. Safe was $29.96 at Walmart. External drive I already had and was a convenient spare for this PROJECT. 500GB is overkill for the data I need to store, but its better to have too much space than too little. It drilled through quickly as for the cement that this safe is made from is almost like hard packed sand and soft to drill. Normal cement will explode at a certain temprature. I found this out the hard way once while using a cutting torch...And even if the USB cord entirely melts into the inside...lack of oxygen will negate truenorth's fears... There is actually a formula you can run according to materials burned...enclosure size etc. if you really want to know all the variables. Quote If you can find a way to create the temperatures of a typical house fire and have associated flame available for the low cost of a USB cable you could test this concern (or just ignore it ) truenorth Hmmm... I have a plumbers torch that gets hot enough to melt a severly damaged 1962-D 90% junk silver quarter into a glob of molten silver at 1640 F , and a similar USB cable that I can torch, will have spare modeling clay left over, and have necessary PPE to experiment outdoors safely. Should be able to drill a hole thru a cement block i have with that 1/2" bit, run cable thru it. Plug it with the clay and set the torch on high burn for 30 minutes to burn the cable off the end of the modeling clay plug and see if the heat penetration is an issue or not on the other side of the brick. I expect the brick to heatsink the heat away enough to avoid the cable from flashing over on the opposite side. Will be interesting. Quote Normal cement will explode at a certain temprature. I found this out the hard way once while using a cutting torch... Yes I have seen that too with acetylene torch before and a chunk of the floor popped as I was heating up a bolt cherry red to try to break it free on a control arm that I got from junk yard for an old Datsun 20 years ago. I am sort of a jack of all trades, mechanics, pneumatics, hydraulics, electronics, and IT. With my favorite being ET and IT. When it comes to welding I enjoy Arc Welding 1/4" steel etc, but haven't had to WELD like that in a while. Mythbusters is my favorite show, and as they say "Don't try this at home, were Professionals" ... Well I'm Professional Enough I think...LOL It is the curious mind and entrepreneurial spirit such as yours that often leads to the creations that can enhance the lives of others (also accounts for the high costs of liability insurance premiums ).

Solve : Windows 8 vs Windows 7 ... and a few questions? |
|
Answer» Interested in finding out the Pros and Cons between Windows 7 and Windows 8. And feedback from those who have used both. Someone told me that it runs faster than Windows 7 and more efficient is this true?Feels the same to me. Though, I imagine like any windows version there are incremental speed improvements in some areas. (Yes, even Vista had this compared to XP, it was just a lot more intensive because of new features that required more oomph such as Aero GLASS). One thing that prevents me from using it properly is the hard DRIVE in my laptop is failing catastrophically over time. Quote Is there a desktop option yet to make it look like Windows 7 Desktop vs the Mobile App Touch screen look that I saw in Beta testing that so turned me away from it as a flop of a GUI? Windows 8 has the standard desktop, just like Windows 7 does. It had that in the Beta's as well as the Release Preview. IMO the switch over is more akin to the switch from Program Manager to The Taskbar, with the added benefit that more of the familiar keystrokes still work from win7 to do the same thing, such as pressing the windows key and then typing a search query still does just that. Quote There is also a video of a guy with 6 displays and his co-workers slipped Windows 8 Beta onto one of his displays. The guy was like.... ok... I want my REAL PC back, i cant deal with the interface madness. Thats sort of how I am feeling even though i am going to have to buy a copy to learn it to support it. There are programs like "Start8" or whatever it is called from StarDock that puts the Windows 7 type start menu back into Windows 8. There are also programs that remove the windows 8 UI start screen altogether. IMO These programs are pointless. If you don't want to experience the new features of Windows 8, just don't switch to it. If (as in your case) you need to learn it to help support it, learn to use Windows 8, not one of those separate tools. Like I said above, if it wasn't for my laptop's hard drive failing I'd probably use it more. One might wonder why I'm not upgrading my desktop to Windows 8 (And, of course I can completely free, Being an MVP has it's benefits).. There are a couple reasons. 1. The Windows 8 UI. Now, don't get me wrong, I really do think it's great. But I don't have a touchscreen. I'm not one of those people that think the entire thing is pointless without a touchscreen, but I think that in many ways using the win8 UI style with a mouse is sort of like trying to use Windows 95 without the right-mouse button. I mean, sure, you can doo all the same things, but the real "power" of the UI is from the new enhancements. A good case and point is that there have been a few times when I was using it on my laptop that I had to suppress the urge to try to do things with my finger. This is pretty interesting considering I've hardly ever used a touch-screen device, so it's arguable that atouch interface is more "intuitive" (And I do try to use that word carefully, people seem to throw it around a lot). 2. I have no idea how it will affect the programs I have installed. I mean, I'd really like to use VS2012 to develop win8 Apps, and I'm sure everything else will work fine, but I've got things setup how I like them on this machine. Pretty much had the same story with win7. I installed Win7 on my laptop long before I installed it on my desktop. I didn't get it installed there until I bought another hard drive. Will likely follow the same path for win8. Buy another hard drive to use as a system drive, clone my current one, and perform the upgrade. If things don't work out I can rollback by just putting the win7 system drive back in. I've seen a lot of people make comparisons between the Windows 8 UI and the "Unity" UI of Ubuntu. Of course the key difference here is that the Windows 8 UI was created and designed using a lot of market research, whereas Unity was put into Ubuntu mostly because Mark Shuttleworth thought it sounded fun. Or MAYBE the Gnome guys didn't send him a birthday card, It's hard to say. Another issue I encountered though, with Win8 on my laptop was the touchpad didn't work about half the time. This was extremely infuriating. I had to uninstall the synaptics driver and use the default mouse driver to get any semblance of sanity back. |

Solve : What is the fastest single core processor?? |

Answer» HI! I just want to know what is the fastest single core processor ever made? Me being stubborn about single core has to do with the ease of assembly programming. Imagine a computer being programmed with the assembly language only. How fast will it not go? Best regards, RogerThe fastest Single core processor is the same as WHATEVER the fastest processor is. At the consumer level, that is probably some variant of the i7. A Multi-core processor is by definition also a Single core processor. All cores can easily be disabled save one. Performance will suffer.Hi BC! I do not fully get your first statement but I interpret it as: The Intel i7 is the fastest single core processor available. The other statement is self explanatory. But you know me, I do not think performance will have to suffer! Best regards, Roger PS What organisation do i7 have? 32X32-bit, or? I am STILL confused about what you said with regard to that processors work with bytes. I have actually seen a screen-dump of the MBR (Master Boot RECORD) where the data for each 32-bit adresses where in one byte per address only. This I do not understand at all. A 32X32-bit processor should work with a 4-bytes wide address bus as WELL as a 4-bytes wide data bus. Finally, I want to beg of your forgiveness for being so crazy and mean the last time we spoke. |
