• How can I make VNC faster?

  - by NickAldwin

  I need to remotely access and use my work computer a few times a week. I want to use VNC because of the price. I've used VNC before, mostly on my own network, where it's fast. However, VNC over the internet is incredibly slow. Even at 256 colors and lower, with Aero turned off, it is unbearably slow. I recently used Ammyy Admin to connect to do something requiring a quick reaction time. Ammyy was really fast, with almost no lag, and it was running in full color with Aero on! How can I make VNC faster, like Ammyy is? I'd use Ammyy, but I would probably run into the 15hr/month limit pretty quickly. Any suggestions? [EDIT] I'm currently using UltraVNC.

• Windows XP not starting up anymore (BSOD)

  - by Richard

  When I tried to start my computer running Windows XP yesterday, as I turned on the screen it was stuck at the "Welcome" screen. I had to reset it. After that, I got stuck at the point where the BIOS should load the OS - I turn on the PC, the Motherboard and BIOS post message shows up, then the blinking "thing" in the top left corner shows up 2 seconds, then everything is black. After I let it run for some time in that mode, it automatically restarts. I'm writing this here from a Ubuntu 9.10 Live CD. What can I do to fix this? How can I find out what is wrong? I'm a programmer and okay with doing (very) advanced things in that terms, so if you know something just tell me and I'll try

• If a change the CPU, must I reinstall the OS?

  - by dag729

  Hi, as suggested by the title, I want to change CPU: actually I have two computers, one with Ubuntu running on an AMD Athlon 64 dual core 5200+ and the other with FreeBSD running on an AMD Sempron single core LE-1250. I would like to swap (I am not sure that this is the correct term...) the CPUs from one computer to the other one, that is take the dual core from the ubuntu pc and put it inside the freebsd pc and viceversa. The mobo is the same. Do you think I will encounter problems?

• Converting an external hard drive to internal

  - by Nathan DeWitt

  I have a WD Elements 1 TB external drive. I'm in a pinch and I need an internal SATA drive. How do I find out if the drive in here is actually a SATA drive? Edit: The WD Elements is a really nice external drive. I gently pried open the top and slid out a 1 TB Caviar Green hard drive. There were four black rubber brackets that slid off easily. One screw removed the SATA -- USB, and then I slid it into my computer.

• Stop Windows 7 from installing critical updates

  - by Rico

  I have disabled Windows Update on Windows 7, but it still downloads and installs critical updates. As with Windows XP, these updates occasionally create problems. But in XP, once I disabled automatic updates, the OS did not override my settings and continue to download and install critical updates. After the most recent critical update to Windows 7, every time I boot up, the USB devices connected to a single port through 4-way hub don't install. I have to unplug the hub from the computer then plug it back in. Then the devices install. I can use System Recovery to solve the immediate problem, but I'd like to disable automatic updates entirely. Why does Windows 7 not respect my settings like Windows XP did?

• Dns works, can ping, but cannot load web pages in browser

  - by user1224595

  Yesterday I changed routers, and my desktop computer started acting up. I could ping websites, and nslookup was able to resolve names to addresses, but neither chrome, firefox, nor ie could load any webpages. None of my other computers connected to the same wireless router have any problems. I connect my desktop to the router through a cheap wifi dongle. I did a wireshark capture of the browser request, and I have uploaded the pcap here. https://drive.google.com/file/d/0B7AsPdhWc-SwbTV0bUJLQXo4UUE/edit?usp=sharing One strange thing I noticed was the spamming of ssdp packets. I am not super familiar with networking, but it seems that it is not a problem with the router, as dns works, and so does dhcp (the desktop is assigned an address correctly). Any help would be appreciated.

• WSUS Looping 2 updates on 2003 servers

  - by Ericrobert

  Good afternoon, Hopefully I can articulate this so that people understand my problem. We have WSUS on windows server 2008. We have 8 Windows 2003 servers. There is an update ready to install KB2982792. We install it then it says there is another update to install KB2728973. Then it says there is another update to install, again KB2982792. This goes on and on. Talked to microsoft support and they confirmed that the update was infact installed and applied to the computer (Checking untrusted certifactions confirmed that for these updates) and their suggestion was to just "Hide update". This is fine except on the WSUS server it still shows failed updates which is not okay with our policy. I'm here to ask for help figuring this out and what I can do to trouble shoot it. Thank you in advanced.

• Getting into the details of game engine programming

  - by Darkslash

  I am interested in learning game programming, but I really have an interest in the lower level engineering in games. I have OpenGL experience, and I am really interested in learning more about implementing AI, Physics, etc. I have a computer science degree, so I really like getting into technical stuff. Many times when I ask about this sort of thing, I get a lot of "Use an engine", "Use Unity3d", "Why waste your time writing code that already exists", etc, etc. My idea was to use simpler libraries such as SFML or XNA so that I could learn how to implement the more complex systems. The thing is, although I do want to write games, I want to learn things that using something like Unity simply doesn't teach you. My goal is not to make a current generation quality 3D game to sell, I just want to make some cool smaller games and learn all I can about the programming side of game development. Is this something that people just do not do anymore? It seems like everywhere I turn people are using Unity or UDK or GameMaker. I fully understand why you would use a tool like these, but I cant see how they would suit my purposes. So where does someone like myself turn? Am I trying to learn something that people just do not bother doing anymore? Is the innovation in this area gone and just all about gameplay now? I'm sorry if this question seems silly, but I am genuinely interested in knowing more about this and meeting more people who are interested in this sort of thing.

• Manually forcing TCP connection to retry

  - by Vi.

  I have a TCP connection (SSH session to some computer for example) Network suddenly goes down and drops all packets (disconnected cable, out of range). TCP resends packets again and again, retrying with increasing delays. I see the problem and plug the cable back (or restore network somehow). TCP connection finally successfully resends some packet and continues. The problem is that I need to wait for a some timeout on point 5. I want to use my opened SSH session now and not wait for 5-10 seconds until it finds out that connection is working again. How to force all TCP connections to resend data without delays in GNU/Linux?

• Prevent Java application from accessing/monitoring/altering clipboard contents

  - by mcstrother

  I'm a student using a service that provides practice questions for standardized tests. The service requires that I access the questions by downloading and running a Java application. If I try to copy anything from any window of my computer (including applications unrelated to the question bank) while the application is running, the copied item is replaced with an obnoxious message asking me to not pirate their copyrighted material. I find this obnoxious, and I also really don't like the idea that any application can slurp up any and all potentially sensitive information that I happen to copy while it's running. Is there are a way to limit the privileges of this application to stop it from doing this? Thank you!

• Can I backup my IMAP Gmail account locally using only Alpine?

  - by BasicObject

  I recently discovered cli email clients and have fallen in love with their speed and simplicity. After playing around with mutt and alpine I decided I favor alpine. I am a Gmail IMAP user and have many years of emails that I'd like to store locally. Is there a more or less convenient way to retain IMAP functionality and backup only the emails that haven't been backed up already on a weekly basis? I have alpine setup with my Gmail with IMAP and it's working great. I'm just wondering if there is a way to make an offline backup or "archive" locally on my computer while retaining the multi device access that IMAP offers. I apologize if this has been asked before, I did search for it and did not find my answer. Thank you for reading.

• How can I check myself when I'm the only one working on a project?

  - by Ricardo Altamirano

  I'm in between jobs in my field (unrelated to software development), and I recently picked up a temporary side contract writing a few applications for a firm. I'm the only person working on these specific applications. Are there ways I should be checking myself to make sure my applications are sound? I test my code, try to think of edge cases, generate sample data, use source control, etc. but since I'm the only person working on these applications, I'm worried I'll miss bugs that would easily be found in a team environment. Once I finish the application, either when I'm happy with it or when my deadline expires, the firm plans to use it in production. Any advice? Not to use a cliche, but as of now, I simply work "to the best of my ability" and hope that it's enough. Incidentally, I'm under both strict NDA's and laws about classified material, so I don't discuss the applications with friends who have actually worked in software development. (In case it's not obvious, I am not a software developer by trade, and even my experience with other aspects of information technology/computer science are limited and restrained to dabbling for the most part).

• block access to certain website types

  - by frustrated teacher

  Need to block access to certain website types without listing each URL to block. Students at secondary school are going to porn sites. Need to be able to block all such access without having to list each possible site URL. Having the Content -- Ratings tab set to None for all categories on the ratings files listed on my computers does not prevent access. Unchecking users may access sites with no rating, even with the security settings set to High, still allows the porn sites to come up. If that is checked, then ONLY listed sites can open and students would not be able to do any research via google, for example. I would rather not have to continue checking each computer and blocking sites as they find them.

• Is embedded programming closer to electrical engineering or software development?

  - by Jeremy Heiler

  I am being approached with a job for writing embedded C on micro controllers. At first I would have thought that embedding programming is to low on the software stack for me, but maybe I am thinking about it wrong. Normally I would have shrugged off an opportunity to write embedded code, as I don't consider myself an electrical engineer. Is this a bad assumption? Am I able to write interesting and useful software for embedded systems, or will I kick myself for dropping too low on the software stack? I went to school for computer science and really enjoyed writing a compiler, managing concurrent algorithms, designing data structures, and developing frameworks. However, I am currently employed as a Flex developer, which doesn't scream the interesting things I just described. (I currently deal with issues like: "this check box needs to be 4 pixels to the left" and "this date is formatted wrong".) I appreciate everyone's input. I know I have to make the decision for myself, I just would like some clarification on what it means to be a embedded programmer, and if it fits what I find to be interesting.

• Is there any way to facilitate switching windows in Ubuntu?

  - by Ivan

  I'm just a student who received my laptop from my uncle, who's a coder, so I'm still getting used to working with ubuntu. I recently upgraded ubuntu from an earlier version, and everything seems to be pretty great. The only thing is that when I open a program, or file, or whatever, it takes up the whole screen. I can only close it by going to the far top left of my screen, or by ctrl+W. Anyways, I find it really hard to switch between programs. For example I really like to have my windows that are open to be accessible by clicking on their icon at the bottom of the screen... Great when writing or researching. Anyways, I really just want to find an easier way to switch windows. Also, I used to love the way I could cube-rotate my screen, and just drag files from one desktop to another, with compiz. Now, its sort of like flipping a coin when I switch windows, is there any way to get my desktop cube back? And yes, I have enabled all the old settings I used to use with compiz. Sorry if what I'm asking is very basic, I know how to use a computer, I'm just not really familiar with the interface! Any help is greatly appreciated.

• Failed 11.10 to 12.04 upgrade and drove me crazy!

  - by Ivan

  Please help me with this! I first tried to upgrade my Ubuntu server from 11.10 to 12.04 thru Upgrade Manager, but never succeeded! Then I tried upgrading thru terminal, which took me ~4 hours as I was warned. When I restarted my computer, my login GUI did not show up at all! (Panic I was!) But when I switched to tty6 and it seemed the upgrade has finished, at least partially and got message Ubuntu 12.04LTS and telling me 12.10 is available. There are bunch of unmet dependencies...."apt-get install -f" may resolve the problem. Then I tried: sudo apt-get -f install, did not succeed! Also I tried sudo apt-get update && sudo apt-get upgrade I got bunch of error message too long to list here. Then I tried: sudo do-release-upgrade still bunch of error message there! There seems a lot trouble with the upgrade from 11.10 to 12.04 for me. Did I miss anything? Anyway, can I ask how I can get the gnome login GUI back? Thanks a lot! Yifang

• Syncing Large Directories/Filesystems using USB Drive [closed]

  - by Alan Lue

  Does anyone have a solution for syncing large directories/filesystems using just a USB flash drive (and specifically without using a network connection)? The objective is simply to sync a user directory between two computers. The contents of the user directory could amount to a large quantity of data—say, a quantity larger than could be stored on any single USB drive—but the aggregate size of changes that must be propagated by a single sync could easily fit on a USB drive. As an example, suppose a user directory is already synchronized between a desktop and a laptop computer. Here's a use case: Some changes are made in the user directory on the desktop. We mount a USB drive onto the desktop and copy whatever changes need to be applied to the laptop user directory in order to synchronize the desktop and laptop user directories. We now mount the USB drive onto the laptop and apply the changes. The desktop and laptop user directories are now synchronized. Any ideas? Alan

• Missing 16:10 resolutions with Nvidia drivers (Can't add resolutions)

  - by Wuinny

  I have a laptop with a Nvidia 9650M GT and used the drivers that Seven brought me. It works fine but Metro 2033 tells me that I have to upgrade my drivers to play the game. So I did it. But since I did a clean install of the new Nvidia drivers, I just have 1440*900 or 4:3 resolutions. I usually played with 1280*800 or 1184*740 (for performance issue) With the "old" drivers I was able to create custom resolution (1184*740) in Nvidia control panel but now when I try it tells me that "my monitor cannot support this resolution". When I insist, it works but soon as I shut down my computer I have to recreate it.. Do anyone have a fix?

• How to configure something like "Reflexive ACL" on OpenBSD?

  - by Earlz

  My U-Verse modem has something called "Reflexive ACL" described as Reflexive ACL: When IPv6 is enabled, you can enable Reflexive Access Control Lists to deny inbound IPv6 traffic unless this traffic results from returning outgoing packets (except as configured through firewall rules). This seems like a pretty good way to keep from having to maintain a firewall on each computer behind my router that gets handed an IPv6 address. It sounds about like a NAT, which for my small home network is all I want right now. Now my modem sucks as a router though, so I'm in the process of configuring an OpenBSD router to do that. I've got IPv6 supported and all that and my OpenBSD router will hand out IPv6 addresses by rtadvd. Now I want to keep people from having instant access to my local network through IPv6. How would I best do something like Reflexive ACL with pf in OpenBSD 5.0?

• Does installing windows format the hard disk?

  - by Jason

  My Google search for ""does installing windows format the hard disk" returns: No results found for "does installing windows format the hard disk". I was quite surprised. I'm hoping to get a quick answer here. Does an install format the hard disk, and destroy all data, including non-os/s data? -Or do you specifically have to say "format" at some point so you know you are losing everything? [I tried to go to SP3, but it doesn't work on my computer. My SP2 disk is fired. I only have a SP1 disk, with a seperate SP2 package. I can't get to Safe Mode to uninstall SP3 ("Windows XP Setup cann run under Safemode. Setup will restart now.). I don't want running the SP1 disk to destroy any non-o/s data.] Thanks.

• Network card dies when trying to wake up laptop from sleep

  - by Bugmaster

  I have a Dell XPS 1640 laptop (aka Dell Studio XPS 16), running Vista. Whenever the laptop wakes up from sleep, my Broadcomm LAN card immediately dies. Any attempt to access it completely locks up whichever program I use to access it. There appears to be no way to re-awaken the card, other than rebooting; note that Vista does not even shut down properly if some program is waiting for the card. So far, I have tried the following: Disabled the "allow your computer to shut down this device to save power" in the device properties. This had no effect. Attempted to disable and then enable the card in the device properties. No effect. Tried ipconfig /renew: this locks up ipconfig to the point where I can't even kill its process. Force-install updated drivers from broadcomm: no effect. Does anyone have any other ideas ?

• Ternary and Artificial Intelligence

  - by user2957844

  Not much of a programmer myself, however I have been thinking about the future of AI. If a fully functional AI is programmed in a binary environment as is used in current computing, would that create a bit of a black and white personality? As in just yes/no, on/off, 1/0? I will use the Skynet computer from the Terminator series as a bad analogy; it is brought online and comes to the conclusion that humanity should just be destroyed so the problem is resolved, basically its only options were; fire the missiles or not. (The films do not really go into what its moves would be after doing such a thing, but that goes into the realms of AI evolution so does not really fit with this question.) It may also have been badly programmed. Now, the human mind has been akin to a ternary system which allows our "out of the box" thinking along with all the other wonderful things our minds can do. So, would it not be more prudent to create a functional ternary system and program an AI using it so the resulting personality would be able to benefit from the third "maybe" (so to speak) option? I understand that in binary there are ways to get around the whole yes/no etc. way of things, however the basic operations are still just 1's and 0's. Again with using the above bad Skynet analogy; if it could have had that third "maybe" option as part of its core system, it may have decided to not launch due to being able to make sense of the intricacies of human nature and the politics of such a move etc. In effect, my question is; Would an AI benefit more from ternary computing as opposed to binary due to the inclusion of -1, or 2, dependent on the system ("maybe," as I call it)?

• Strange ports on default install of W7

  - by Sabre

  I have a base new install of windows 7, and when I went to look for something else I saw the attached netstat output. What concerns me is that this is Windows + Truecrypt + drivers, nothing else installed. The sequential high ranged ports belonging to several different seemingly not out of place services seemed odd. So I torched the install, used Active@ to scrub the disk, re-downloaded the ISO from MSDN, and did a fresh reinstall, viola, they are there again. It just seems out of place, I have seen a many netstats over the years, this one just strikes me as odd, so I started thinking rootkit? (JUst FYI, when I reloaded I named the machine "Error" so that is why the task manager reads the computer name as such.) So I would like to know if anyone else could explain it, and therefore is may be normal, or would they be worried as well, and should I start considering I have some very strange thing occuring on my network?

• Is it possible to replace the Logitech G500 wire without rebuying the mouse?

  - by leladax

  It has to be replaced ideally in whole, from the point it starts inside the mouse (with a white 4-5 piece of wires connection) to the end (of the USB connector to the computer) or at least to a considerable length because there is fatigue very near the mouse and the more I fix it there with soldering the closer it gets to being unfixable or reaching towards 'inside' the mouse where fixing it will be hard or impossible. So I wonder if there is a way to get a replacement of the whole thing or at least the inside-the-mouse connector to a certain length. Also I wonder if other mice types are identical in the connector of the inside.

• Need old version Firefox Java plugin

  - by Bryan

  I need to use Java 1.6.0_20 for the software I'm running. I went to the Oracle website and downloaded jre1.6.0_20 and installed it on my computer, but can't seem to get Firefox to load Java. If I download directly from http://www.java.com/en/download/manual.jsp, the plugin works fine but is the wrong version, and I can't find on www.java.com anywhere to download any of the previous versions. According to the help (can't post link because of spam prevention), I need to go into the Java Control Panel and enable it for Mozilla. I've done this multiple times, but every time I go in to the control panel and check the box, click Apply and Save, as soon as I go back in the box is unchecked. Does anyone know either why the box is unchecked, or where I can download the old JRE that also is configured for Firefox?
