Solve : Fact or False? Windows vs Linux OS interrupts? |
|
Answer» So I was on the phone with a engineer from a international automation company that I cant specify here, because I dont want to bash the company name for what I feel is a engineer who might not know what he is talking about. While I myself do not know everything, the conversation I had about a problem with software with statistical reporting from sensors throughout the entire automation machine seemed wrong. To me it seems like they have some coding issues and they are just trying to sell us on the Linux version vs fixing flaws in their statistics portion of the software.Bingo.I used to work in automation software. But I do not have a quick answer to the question. An Intel CPU can handle a number of hardware interrupts. An IBM compatible Desktop PC is NOT well suited to get time-sensitive data over a network. Unless the data itself is "smart" and has time stamps embedded in the data. In any case, for a critical application, no standard off-the-shelf system software should be used except a package that has been made for machine automation. The people who do this use tools available from Intel or IBM. An often a custom motherboard has to be used. Here is a general reference about the hardware interrupts for an Intel system. http://retired.beyondlogic.org/interrupts/interupt.htm#2 System software may disable interrupts for unspecified reasons. This can cause loose of information is some cases. If custom software is out of the budget, then remote controllers should be used to gaiter data cache it for a PC. At best. expect to have an error of 55 ms on any stock PC. Worse if the OS disables interrupts at random times. Linux kernel can be customized for a specific application. It is not the same as a typical Linux distribution. What the OP describes is often called "machine automation" in the industry. Meaning a software and hardware package that controls a factory of PLANT that requires constant frequent samples and adjustments. Here is a relevant link: http://www.automation.com/library/articles-white-papers/opc-articles-and-white-papers/3-reasons-linux-is-preferred-for-control-systems The point here is that Windows was never intended to be a universal tool kit for everything. Still, you can design a complex system using Microsoft software, but some more hardware is needed Intel suggests using a system with custom hardware and software. http://download.intel.com/design/network/papers/30405401.pdf Read the links. End of my two cents. Quote from: Geek-9pm on August 23, 2014, 08:55:22 PM An IBM compatible Desktop PC is NOT well suited to get time-sensitive data over a network. Unless the data itself is "smart" and has time stamps embedded in the data.If only there was a Transfer Control Protocol That operated over The Internet Protocol that requires Time information to be stored in the data packets. Oh well. In any case, for a critical application, no standard off-the-shelf system software should be used except a package that has been made for machine automation. The people who do this use tools available from Intel or IBM. An often a custom motherboard has to be used. Quote Here is a general reference about the hardware interrupts for an Intel system.That is the information on hardware interrupts on an 8086 CPU. More recent CPUs are compatible in real Mode but they are NOT compatible at that level in either Protected or Long Mode. Not to mention ACPI and the PCI bus making those hardware interrupts less relevant. Additionally, when it comes to automation software, they will typically use an add-on board. such an add-on board will fire non-maskable interrupts that cannot be ignored regardless of the OS. Quote System software may disable interrupts for unspecified reasons.No, it can only mask certain interrupts. Non-maskable interrupts cannot be ignored or masked, as you ought to know. Quote Linux kernel can be customized for a specific application. It is not the same as a typical Linux distribution.based on the Original Post, the choice is between Linux Software and WIndows Software. The company does not provide a specially tuned Linux distribution, it is simply Linux software. Given the scenario it is almost a certainty, I would expect, that there is a hardware dongle (PCI/PCI-E Card) involved. So really the issues have nothing to do with either OS in particular and everything to do with the software (Either drivers or control software) offered by the vendor. And that is fine. But when Engineers start lying through their teeth making up garbage, that is when you need to reevaluate your relationship with that vendor. If everybody in the company is as trustworthy as a salesman, who do you go to when you want to understand how things work in reality? Obviously the limitation is not one of Windows itself but a limitation of their Windows software. Quote from: Geek-9pm on August 23, 2014, 08:55:22 PM End of my two cents. More like twenty dollars. Well posted Geek! Thanks for the detailed and well thought out information everyone. |

Solve : My Corporate Rant? |
|
Answer» We have about 400 XP workstations at our facility, so our corporate office sent a "Migration Team" to install Windows 7 for us to lighten the load. Part of that migration was to adopt some new security policies. yay We've now went into a dual monitor obsession and we're having to install video cards in many machines. Workstation #1: After installing the card, I TURNED on the machine only to be prompted by bitlocker, telling me to enter a security key(Standard security procedure-Hardware Change). After sitting on hold with the service desk for 23 minutes, I gave them my ID and they SAID that the user wasn't AUTHORIZED on that drive(Standard security procedure). We tried mine(local facility admin) and any user I could think that actually used that machine in the past....Nothing. Her advice was to REFORMAT THE MACHINE!(Standard security procedure). I finally came across an ex-employee ID that let us in. Great! I logged in and downloaded the video card drivers. I couldn't run the EXECUTABLE without admin credentials(Standard security procedure) sooo.... The local administrator account wouldn't work for some reason. I tried my personal admin credentials which let me launch the setup. I soon found out that all local administrator accounts had been renamed.(Standard security procedure) The setup started copying files over to the C drive and ACCESS DENIED(standard security procedure). I had to copy the drivers from the network location I'd downloaded them, to the local desktop only this time, the local admin account worked, and my admin account wouldn't. REBOOT TIME!..... BITLOCKER STRIKES AGAIN! (Standard security procedure) Back on hold I go... She told me I had to go into the control panel, suspend bitlocker, and leave it like that until it re-writes it's configuration(or whatever). I'm finally back into Windows and not much to my surprise.... no dual monitors, so I go into the display settings to activate the other monitor...It's not there. Soooo I go to the device manager to see what's going on and it shows the other display adapter with an exclamation mark on it. I tell it to check the INTERNET for any driver changes and of course...MICROSOFT is a blocked download site. So I basically had to hack the registry to let me download from Microsoft until the next Big Brother GP update was forced upon me. That allowed for Windows to search for an updated compatible driver (Not sure why the OEM driver didn't do it) and the monitor then activated and I went on my merry way. Not funny but you sound like my daughter and the team she works with. What? My post was not meant to be "funny". The Windows 7 upgrade where you work sounds badly planned and executed. I don't believe he was responding to you ST Dadair is not the OP...just a recluse... |

Solve : National Broadband Network.? |
|
Answer» If you live down under, you already know what this is. The National Broadband Network (NBN) is a national wholesale-only, open-access data network and is under development in Australia.http://en.wikipedia.org/wiki/National_Broadband_Network The service is now working, but not without its critics. Other countries are looking at this as a possible model of what happens when tan ATTEMPT is made to tie an a very large area with unified fiber network for home users. Notice the use of the term FFTP. Quote Approximately 93 per cent of the population was planned to be serviced with fibre to the premises (FTTP)Do you have it? Do you like it a lot? Would it work in other countries? |

Solve : DNS attack affects NZ's biggest ISP? |
|
Answer» In New Zealand this is big NEWS. Cyber CRIMINALS blamed for three-day DDoS.(It was on Sept. 6 and 7, this year.) So what did they recommend as a work-around? Quote As the problems continued over the weekend, Spark advised users via Twitter and the web to switch their automatically allocated DNS servers to others such as Google'sComments?I'd have liked to see them having better protection over their DNS servers but their work-around is totally sound. I imagine they will step up protection of their DNS servers from now on.Curious as to what you are running for hardware specs? Depending on what you have for hardware there may be limitations to distros etc. Most people I know using xubuntu are running it because they are running older Pentium III generation and early Pentium 4 generation SYSTEMS that have memory limitations to MAX supported RAM. And xubuntu is a lighter weight distro than that of the ubuntu os to work better with systems with lesser RAM and CPU processing power.HuuuHH ? ? |

Solve : Delta Airlines Wifi - Requires Specific OS to surf? |
|
Answer» So I flew home from Oklahoma to Manchester, New Hampshire yesterday... and on my flight from Atlanta to Manchester, NH, I decided to connect to the Delta Airlines Gogo wifi that they turn on after they reach greater than 10,000 feet elevation. I figured I'd connect to it from my netbook. Sadly they seem to have a OS requirement to connect to their wifi, which is stupid. Anyone know "why" they would have an OS version requirement to connect to their free or paid for wifi when the browser is a match to the requirements, and should be the only requirement is that the browser be a specific version or newer? Yes...because they can...at 27,500 feet they have you as a captive audience.With the appropriate add-in you can always change your user-agent to report a supported OS. I doubt they have much reason to actually have it set. Quote from: BC_Programmer on September 28, 2014, 07:01:01 PM With the appropriate add-in you can always change your user-agent to report a supported OS.

Solve : Malware in BOS Threats.? |

Answer» Can a virus get into yhour BIOS? SecurityThere is an old saying, "If something can go wrong - it will." EDIT: Qustio0n. Which motherboards have detachable BIOS chips?They are all detachable with enough heat to get lead to flow! If your asking for socketed ones... I have seen some that come in sockets, but ever since they implemented rollback of BIOS on many motherboards, the need to remove a ROM chip that was flashed with a bad flash is not as much of a problem as in years past where you created that bootable floppy and booted your system up and it was Flash and Pray, and a bad flash would kill the functionality of your motherboard in which your options were to get a replacement ROM and swap chips, since if you flashed the system with a bad rom that didnt at least function to allow seeking of the floppy drive on boot, you were dead in the water. I have had friends who had this happen as a result of using worn 1.44MB floppy disks or dirty drives where the DATA read was corrupt, and there was no error checking of the ROM file before flashing. Back in those days this was an expensive mistake. I ran on whatever BIOS version came with the boards back then for fear that I would kill a Pentium 75mhz and have to then go backwards to a 486 DX 66 which was not quite enough for the games that ran ok on the Pentium 75. If you look at the motherboard before buying it you can see if it has a socketed ROM or not. But these days there is rarely ever a need to swap the BIOS ROM chip. Thanks. Some research shows new boards now have special EPROM. These chips have only eight legs and are easy to remove. Both ASUS and Gigabyte are using these. Maybe many pothers. You should hang out in our Malware Forums and see how many instances are listed in the last 10 years before sounding a sheep's call... Quote from: patio on September 28, 2014, 05:08:02 PM You should hang out in our Malware Forums and see how many instances are listed in the last 10 years before sounding a sheep's call...With due respect, are you saying that it never happens? Or is is so rare that it should not be considered? It is very, very hard to verify the pretense of malware in the BIOS. This was a topic in the 2013 Black Hat THING. http://www.blackhat.com/us-13/briefings.html Also, Info-world did a article. BadBIOS: Next-gen malware or digital myth? Thanks for looking. Yes...that's what i was saying... Quote from: Geek-9pm on September 28, 2014, 06:12:32 PM It is very, very hard to verify the pretense of malware in the BIOS. This was a topic in the 2013 Black Hat thing.it's relatively easy. The BIOS ROM is usually shadowed and while it is going to require Ring 0 to read that memory directly, anti-virus and anti-malware programs already implement kernel-mode components for their AV features. The same heuristics already present for standard executable files can be applied to the BIOS code, because that BIOS code can be acquired. The main problem in understanding BIOS infections is that people equivocate it with a rootkit. In reality, all BIOS interrupt vectors are replaced with the OS loads; so no BIOS code can run post-boot process. So once an OS is launched, that infected ROM will be fully visible by driver-level software that can read it. That could then be scanned. Additionally, because of the varied firmware/software present in a BIOS code, it cannot be infected in a way that is malicious; any malware that "infects" a BIOS will simply corrupt it. You might expect, "ah, but then the system won't boot" but that is incorrect. Aside from the BIOS checksum being wrong and preventing it from being used, almost all modern systems have two BIOS chips. Mine doesn. My old PC does as well; the second BIOS chip is inaccessible and is switched to via differing methods within the solid state of the motherboard and chipset, and typically is implemented with a ROM rather than an EEPROM (or, an EEPROM for which no software method is exposed to make it writable). Any problem in the main BIOS would cause an error and the backup BIOS to be used. The backup BIOS being essentially the factory default BIOS. Most of the time it will only use the backup BIOS to perform a Flash and essentially rewrite the primary BIOS with that backup, then reboot the machine. That is, a infectious design would need to be specifically coded to deal with the differences between various platforms; additionally, differing manufacturers and even models. For example a BIOS infector designed for my old PC (which has Dual BIOS) would not work on my current system because they are designed differently, and the checksums are stored in different locations and also use different calculations to come up with that checksum. Quote http://www.blackhat.com/us-13/briefings.htmlthe article covers TPM, which is a SPECIFIED interface to provide a more secure system. TPM is supported on many systems however it bears mention that TPM requires a hardware dongle to be plugged into a TPM header on the motherboard of a system that supports it, and is never included with the motherboard (basically if TPM was required you would shop around for a module from different competitors). |

Solve : virus ??????????? |
|
Answer» I have average computer skills at best. Be very careful of freeware sites. I only trust one ( Snap FILES ) . A couple months ago I went to freeware site, don't know the name. Anyway as SOON as I clicked on this site it started to download something. I reached up really fast and clicked computer off ( hard kill ) with my WIFI with no wires, maybes theres other ways to disconnect from the net. Maybe airplane mode, since I GOT windows 8. Luckily I was ok. Rogue security software designers create legitimate looking pop-up windows that advertise security update software. These windows might appear on your screen while you surf the web.You may be still infected. |

Solve : A fundamental USB security flaw? |
|
Answer» This is not news. Just a heads up. Some forums report the problem is real and there is no fix. Here is a quote for one of a few: Remember that fundamental USB security flaw that a pair of researchers unearthed back in July? You know, the one that ALLEGEDLY affects every single USB DEVICE in the wild for which there is no fix for. While they did publically demonstrate the flaw using a piece of MALWARE they created called BadUSB, the duo elected not to release the code. A couple of other researchers, HOWEVER, decided to throw caution to the wind by posting code for a similar attack on Github. During the RECENT Derbycon hacker convention, researchers Adam Caudill and Brandon Wilson revealed that they were also able to reverse engineer the USB firmware that Karsten Nohl and Jakob Lell spoke of a few months ago.Source: http://www.abovetopsecret.com/forum/thread1035410/pg1 What do you think? |

Solve : Arduino Uno vs BeagleBone vs Raspberry Pi? |
|
Answer» I found this site I want to share with you. Do you have an old PC lying around the house which absolutely no one wants? Then you can convert it into a dedicated controller. Communicate with the real world via the parallel printer port on your PC. Simply connect printer cable from computer to Centronics CONNECTOR on relay board. There are 8 relays each capable of switching 12VDC/10A or 240VAC/5A. Each relay has an LED to indicate when it is operated. We provide two sets of COMPLETE, stand-alone software to control the relays: one works under DOS so you can write your own batch files to control individual relays, the other under Windows 3.1. Needs 12VDC center positive 2.5mm power supply. PCB Size 6.75" x 2.75" (version 2) (CPS74)I have a RaspBerry Pi which I played with a bit when I first got it but decided it was too underpowered and slow to be useful so now it sits unused. Perhaps someday I'll think of a use for it.It is not easy to estimate the power of a micro controller. For mechanical jpbs, it works fine. But doing a 3-D shooter game is at the upper limit. n between taht are many task that are good for a low-power low speed CPU. Here is a link: 20 Awesome Projects for Raspberry Pi Microcomputers |

Solve : Most People buy a CPU to upgrade, how about buying a serious downgrade? |
|
Answer» While looking at the CPU support list for the Biostar MCP6PB M2+ motherboard in my older gaming system, a 15 Watt CPU caught my eye. The Athlon 64 2650E 1.6Ghz Single-Core with 128k L1 and 512k L2 cache. most people buy CPUs that are far above and beyond the current software needs I completely agree. And they spend way over the odds. I timed my Core 2 Duo 2.3 GHz, 2GB laptop, bought ex-CORPORATE refurbished, for 179 UK pounds in 2012, against my 3.0 GHz quad core Phenom II 4GB desktop (700 UKP in 2011) at video transcoding using Ffmpeg, and the laptop came in at 80% of the speed, for 24% of the price. I can buy an ex corporate Core 2 Duo 3.0 GHz desktop with 2 GB RAM, a 250 GB hard drive, and Windows 7 Pro for 129 UKP, 18% of what I paid for the AMD desktop, which was, admittedly, a vanity purchase. (It's a Shuttle). If I was prepared to have Vista Home Premium I could have a Core 2 Duo 3 GHz with 4GB RAM and 160 GB for is 99 UKP, 13%. I too have had good luck with refurbs, specifically buying the HP Business Class off lease systems. At my last job we had a mix of workstations and Consumer grade PC's that were created into servers which were Pentium 133 Mhz through Pentium III 800Mhz in processing power and MANY of them were GETTING really really tired by the frequency of help desk calls for systems acting up. They were all running NT4 SP6 and Windows 2000 Professional SP4. The business was a "Not for Profit" Coop Food Store and so we had a very tight budget to work with for IT. I ended up finding that Tiger Direct had put for sale Pentium 4 ( 2.8 Ghz ) HP Business Class Refurb SFF systems for just $129.99 with Windows XP Professional, and this was back when buying Windows XP Professional alone was $139.99. I was able to convince my director to buy 40 of these systems and we ended up getting a volume discount $10 off each PC at just $119.99 each. I quickly implemented these systems and pulled out the very tired systems, and the users were all very happy, and the GM was very happy that I basically got them a workstation upgrade for the slowest/worst off of the systems for less than the cost of the XP Pro OS alone and got the PC's along with it basically for free at that price. I was at this business for 2 years with those refurbs and only had 1 out of 40 systems require a hard drive replacement, but i have a strong feeling that it was user induced since the user wanted the computer on top of a filing cabinet vs on the desk to free up desk area and with the slamming of the filing cabinet, they probably jarred the hard drive as it was SPINNING and crashed it that way. I a few months later also saw other HP Business Class systems for sale as refurbs for $79.99 ( around 2008 ) with NO-OS and bought one for myself:: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4166230 HP Compaq EVO D500 Pentium 4 1.7Ghz 256MB RAM 20GB IDE HDD CD-ROM The cool thing with this model was that while it was sold without an OS, it still had its Windows 2000 Professional Key Sticker on it and so I just needed to use the Windows 2000 Professional installation CD and then enter the key that came originally with this computer. Not sure if someone was suppose to remove the key from the barebones or not, but it was nice that it was there to create a dual-boot Windows 2000 Pro SP4 / Linux system. While many refurb systems have short warranty terms, HP gave these systems a 12 month warranty, but because the Business Class HP's are a solid product line I didnt have to send any back. Lots of money can be saved by buying a good refurb system, although you cant just buy any refurb, you need to know what you are buying so you dont end up with a system that is not a good match to your application. But same goes for new computers as well. You need to know what you need for processing power and features vs buying a computer such as an off the shelf Wal-mart eMachine for example for $289.00 and trying to play heavy graphics and resource hungry games on it. Chances are its going to need a lot more than just a video card and power SUPPLY upgrade to play those games and its more than likely a slow and energy efficient system intended for everything but heavy resource and graphics gaming. |

Solve : Play Random Video from List? |
|
Answer» So I have a bunch of movies that I legally own, and currently I have to navigate and select a specific file to watch. I was wondering if anyone had any suggestions of tools out there that allow for this? Create a playlist in your favorite media player. Curious as to how you can pass an instruction from say a C++ or batch instruction to the media player to tell it to play a specific number from list though? Unless there are some switches to add beyond say ( media player - "file to open and play" ) such as VLC.exe "PlayThisVideo.MP4", it will only play the specific video file called upon. So I was thinking that if the DIR output was passed to a text file and the random generator read in a specific line in relation to the random number it comes up with from the DIR command which shows the number of files at the bottom of the listing, that was a way to know the parameters of which to stay within for a random number generated and so a number generated could reference to a line that the file is listed on in alphanumeric sequence. Is there a media player that can handle MP4 or AVI playlist from command from cmd shell that you know of which could take in a random value passed to it?You may want to read this. You can edit a playlist in C++ and submit it to WMP. https://code.msdn.microsoft.com/windowsapps/Playlist-sample-3d80daee Applies to Windows 8.1 and you can still get a free evaluation.hmm interesting.... going to dig further into the content you provided. I wasnt aware of microsoft offering these code EXAMPLES etc.I was using Music files but this should ALSO work for Video files. You may need to change some of the properties, and of course you'll probably need to tweak or remove things like the MsgBox, but this should get you started with a VBScript solution, I think. -You'll want to change the file extension. I was having it play .FLAC music files. Obviously you'll want .AVI or other file types. You'd need to change the If appropriately. -Naturally you'll want to change the folder as well. -Right now it will show a messagebox and when you press OK it will change the file Windows Media Player is playing to a new random file. If you press cancel the script exits (and quits the Media player instance). I imagine some of that may need revision as well. It could also be revised to work recursively I suppose but that was too much of a PITA for me to justify doing as part of a first pass Code: [Select]Dim WMP Dim FSO Dim DirGrab Dim iterateFile Dim FileListing Dim ChosenFile Set FSO = CreateObject("Scripting.FileSystemObject") Set DirGrab = FSO.GetFolder("Path\To\Folder") Redim FileListing(0) Dim Count Count=0 For Each iterateFile in DirGrab.Files grabExtension = Right(iterateFile.Name,InstrRev(iterateFile.Name,".")) if(StrComp(grabExtension,".flac",1)) Then Redim Preserve FileListing(Count) FileListing(Count)=iterateFile.Path Count=Count+1 End If Next Continue=true Set WMP = CreateObject("WMPlayer.OCX.7") Do While Continue ChosenFile = FileListing(Int(Rnd*Count)) With WMP ' saves typing .settings.autoStart = True .settings.volume = 50 ' 0 - 100 .settings.balance = 0 ' -100 to 100 .settings.enableErrorDialogs = False .enableContextMenu = False '.URL = ChosenFile .OpenPlayer(ChosenFile) End With Continue = MsgBox("Press OK to shuffle and play a new track.

Solve : Making Money from J2ME!!!? |

Answer» I am a java programmer and I KNOW to program java mobile phones such as Nokia, Samsung or like that. Note: this is not meant to be a comprehensive guide on every detail of these applications and resources. In fact, such a guide could more accurately be described as a book. However, we will give you an overview of the different tools you can use and where to find more information. These tools require varying levels of experience and if you've never touched code before, you might want to check out our guides linked above. first However if you're ready to move from theory and syntax to actual development, here's what you'll need.Have Fun! BTW: Python is one of the five languages suggested by life hacker. Highly recommended. You Tube on Python https://www.youtube.com/watch?v=8zSNzUAfohA Thank you both for your advice.I also personally agree with your views.I also know android programming but I have mastered java programming for mobiles. OK thanks... By the way, if I master android programming then can I make money out of my apps?? Is there any such SITE? Please help...The Google store collects apps from developers who create quality android packages. Many are free to help get the developer known to the community. Later, the developer offers a newer version of his app for a modest price. Possible example. You create a new and very fun game that runs on almost any android. The first version is free. Later, you make a bigger and better version and it sells for 99 cents in the store. In the first year you sell a million. Google keeps 49 cents and gives you 50 cents for each SALE. You then have a coll $500,000 in the bank. All you had to do was write real cool killer game. Yeah, yeah. Lots of people will say you are just dreaming. Do a Goolge search on: Get Rich doing Android Apps. Most of the remarks are negative. But somebody is making money. L:ook at this: Forbes is a serious business magazine. Look at what they report. How Much Do Average Apps Make? Quote The last few years have seen an unprecedented number of people rushing to develop mobile apps for iOS and Android. But looking at the installed user base on each platform and information on the payouts made by the different companies, it appears that the vast majority of developers will find themselves with little revenue to show for. ...But read the whole article. Google has 900 million users, while Apple follows with 600 million. That is well over a billion users! So even if you could sell to just one user in a thousand, you could still get over the million sales mark! Don't stop dreaming! Quote from: Biswajit79 on November 03, 2014, 11:33:44 PM By the way, if I master android programming then can I make money out of my apps?? Of course you can, you would just put it on the Google Play Store. However the hard part is coming up with an idea and actually building an app that people will want to pay for. Alternatively you can create a free app and put advertising inside it. |

Solve : font too small? |
|
Answer» I just BOUGHT a new windows 7 computer. I finally got the fonts for the computer and the desktop icons large enough that I can read them... Problem is the fonts in windows live mail...They are much to small. Is there any WAY I can make them larger with out messing up the rest of the fonts on my computer?? Windows live mail 11.. I ALREADY tried going to read and making the font larger there, but it didn't change anything....Did you SEE or read tutorial links such as http://email.about.com/od/outlookexpressrichedit/qt/Change_the_Default_Font_Face_and_Color_in_Windows_Live_Mail.htmThanks, but this doesn't address the problem with the font being too small. The contacts list and mail received is so small, I can hardly see it...This article shows how to make the font bigger when composing mail, that is not what I am asking.You can hold down CTRL in any browser and use the scroll wheel to increase the page size...or the + button...Guess I am not doing something right. I held down the ctrl and scrolled, but nothing changed.. Quote from: Marjorie on October 26, 2014, 12:01:59 PM ... I held down the ctrl and scrolled, but nothing changed..Did you scroll using the vertical bar on the right side? I'm sure Patio MEANT to use the scroll wheel on the mouse itself. |

Solve : Black and white photos are tinged green.? |
|
Answer» I have an Epson Stylus PHOTO RX500 printer with a Mac computer and I used to be able to print perfect B&W photos. Suddenly,when I print on glossy paper, all the darker colours are tinged with green even though I have no colour controls set. However, I get perfect B&W when I print on plain paper. Does anyone have any idea what the problem is please. A print test page is showing no gaps in the result indicating that all the print heads are clean.Are you using genuine Epson Ink or a cheaper knock off brand? Surely though, low magenta ink should not cause the green tint?Photos typically print using a combination of coloured inks, black is formed by combining Cyan, YELLOW, and Magenta. (I don't know/recall why Photo's don't use the black ink, it may have to do with how well it takes to photo paper) It is no coincidence, I feel, that Cyan and Yellow- without Magenta - form Green.Have you run any maintence such as head cleaning?Thanks BC that combination of colours makes sense. Superdave, I have already tried a head clean. However, by experimentation, I have DISCOVERED that using the Plain Paper profile when printing on Premium Glossy Photo Paper, gives perfect results in black and white with no green tints. I suppose that might suggest the Glossy Paper profile might be corrupted but I get perfect results with colour printing using it. So that solves my immediate problem but I obviously need to resolve the green tint problem. |

Solve : What will bluetooth do to my keyboard?? |
|
Answer» Hi - Why is the short answer " No...you don't want it" ? ? Not that I'm excited to be Geek-9pm's advocate, but from the sounds of it the OP has a Tower PC which likely doesn't include bluetooth capability.He said: Quote I have Windows 7 in a Lenovo tower.He wanted a smaller keyboard. He did not mention PORTABILITY. But simply, Bluetooth does not mean smaller. Smaller means smaller. So the short answer is you don't want Bluetooth if the objective is just smaller. Then he goes on to say he does want wireless. Then there is infrared keyboard. Another kind of wireless. But you have to wear special glasses to find the keyboard. Hi - Since I have had several people make remarks let me clarify. I do have a tower that does not have Bluetooth capability. I want a mini keyboard because I never use the right 1/3 of my present keyboard. Since I am getting a new keyboard I might as well get a wireless one and do away with one wire. I know nothing about Bluetooth because I don't even have a cell phone. I am of the generation that remembers when long distance calls cost extra. You have made things a little easier. I will go to Best Buy and see what they have. Thanks for all your HELP. Bob Quote from: BC_Programmer on March 30, 2016, 07:14:22 PM Not that I'm excited to be Geek-9pm's advocate, but from the sounds of it the OP has a Tower PC which likely doesn't include bluetooth capability. Whether he chooses a wireless set or blutooth it'll still involve a dongle/reciever... I was just curious to why Geek was discouraging a Bluetooth option...that's all. I guess we'll know after he goes shopping.I use Bluetooth. In most CASES, including yours, I'd recommend either a wired keyboard or a non-bluetooth wireless one with it's own dongle. Bluetooth keyboards generally don't include the dongle so this would need to be purchased separately and they can be a total pain to set up pairing.etc. A conventional keyboard with a dongle generally just works out of the box with no setup required.I prefer Bluetooth mice and keyboards over the crappy wireless ones that come with their own proprietary dongle. Yes, you will need to buy a Bluetooth dongle but they are very inexpensive. Once you have a Bluetooth dongle attached to your computer you can now use a whole plethora of devices such as mice, keyboard, headphones, speakers, GPS, etc... It's true you need to pair a Bluetooth device with the dongle before using but it's pretty simple really, not anything to warrant losing any sleep over. Just because I said he didn't want Bluetooth.. He went on to say he did not use part of his keyboard. Maybe he might consider using half a keyboard... [attachment deleted by admin to conserve space]Hi - I found a slim keyboard that was wireless on Amazon. I got it and it seems to be what I was looking for. Works fine. Thanks for all the information and help. Bob. |

Solve : USA: One Reason Not To Go Online After May 5.? |
|
Answer» I just read a post by By Alexandra Blackshaw on Smarter Web Life . Earlier this month we saw thousands of people across the US get their hands on the the latest Online ID protection from SaferWeb, after yet another increase in identity theft and web-history monitoring. Huh? Lack of availability? Whee do I go to stand in line? EDIT: Please help me understand what she said. Is this really just another PR for some late coming security company?Marketing nonsense for some WORTHLESS VPN service. Ignore it. Amusingly I get the title "1 Reason Not To Go Online If You Live In UK" so they are clearly using the visitors IP address to fill in the correct location to make it appear more relevant to them.Camerongray, thanks for the response. So this was just a lame PR blog thing. I fell for it. BTW: Would it matter much if an INDIVIDUAL went VPN all the time? My understanding is that most pf the time you do not need it when e your BANK already has a secure connection anyway. And I don't see have VPN would stop identity theft. Mine says Canada. Also interesting, is that the entire post content is blocked by uBlock. The comments are where the real gold is, though. They are all 100% fake. slap any of those comments into a quoted google search and see that these "people" have made the same comments quite a number of times. The comments also appear to have been somehow submitted before the page was put online. (According to web.archive.org and memento) That's a pretty amazing feat. Mine said US also! The top of the page said that, it is an "Advertorial" that was all I NEEDED to read! Geek you're about to be limited to 1 News story a month if you don't find better sources...I am sorry... |
