  • Does programmable hardware exist to allow hardware to be programmed by computers?

    - by agentbanks217
    I am a programmer and I have never really dealt with the hardware of anything, only software. I want to start building things that I can control from my computer using programming. My question is are there such devices on the market that have a programmable interface or API? For example, I want to build a automated window blinds opening/closing device, and I would like to be able to control it from my computer e.g. writing an app or some code to schedule them when to open and close. I would like to know if there are any devices that can be programmed to do that (the computer part)? Thanks!

  • How to forward traffic using iptables rules?

    - by ProbablePattern
    I am new to iptables and I have been doing Google searches for a few days now without finding a good solution to this problem. I have computer A with a public ip address (say 192.0.2.1) that can access the Internet unrestricted. I have another computer B with a private ip address (192.168.1.1) that can only access computer A. How do I use iptables to forward network traffic from B through A to the Internet? I need to use http, ftp, and https in order to use apt-get with sudo. Both computers run Ubuntu linux. I have tried using Squid but I think it is far too complicated for what I need to do.

  • What can cause a black or blank screen when pressing logout or switch user in windows 7

    - by Medran
    The situation I have here is related to a brand new dell machine with a GTX260 video card. Put simply after one user logs in when that user either 'switch users' or 'logs out' windows goes to a black/blank screen. The TV screen that is used with this computer previously functioned fine with fast user switching on an XP machine. The new computer is windows 7. The TV is not outputting any error messages like 'no signal' or anything else that would be displayed if the computer was off. You can fix the problem by cycling the input on television, after cycling the input the welcome screen appears as normal. What I want to know is what on earth is windows doing that would cause the video card to stop sending the same signal to the monitor when the user logs off or switches users. I mean as far as I can tell the resolution is identical between windows and the welcome screen. Or perhaps if somebody has experienced this before a fix would be great too.

  • networking without port forwarding

    - by Wallacoloo
    I'm trying to add networking functionality to my game. I want any user to be able to host the game, and anyone to be able to connect as a client. The client sends info to the host about their player's position, etc. When the host receives a message, it validates it and then broadcasts it to its other clients. I will primarily be dealing with UDP, but will also need TCP for chat & lobby stuff. The problem is that I can't seem to get a packet sent from the client to the host or the other way around without enabling port forwarding on my router. But I don't think this is necessary. I believe the reason I need port forwarding is because I want to send a packet from 1 computer on a LAN to another computer on a different LAN, but neither of them have a global ip address since they're in a LAN. So really, I can only send packets targeting the other network's router, which must forward it on to the machine I want to reach. So how can I do this without port forwarding? Somehow a web server can communicate with my computer, which doesn't have a global ip, without port forwarding. And I've played plenty of multi-player games that don't require me to enable port forwarding. So it must be possible. Btw, I'm using SDL_Net. I don't think this will change anything though.

  • Setting up remote filesystem access without root privileges

    - by Luke Massa
    OK here's the situation. I have a computer A with complete admin access, and computer B (actually an account I login to) with very limited access. I am trying to make it so I can access a device on computer A (an external harddrive) on B. If I had more access to B, I would just mount the device on B, but I can't do that. I can ssh both directions, so theoretically I can copy data both directions, so it should be possible. I think a NFS might be helpful for me, but from what I've looked at, they all require the client to at some point perform a "mount" operation, something my client can't do. Thoughts?

  • How to prevent boot manager missing after cloning a win764 image using Ghost 2003?

    - by hirogen
    I am running ghost 2003 command -fdsp, but once we have cloned the image and restored it onto exactly the same make and model machine, we are force to run win7 setup and run a repair which fixes the boot menu, I want to prevent this requirement to fix the problem, any suggestions besides the obvious of using Windows AIK tools, new versions of ghost/clonzilla. I want to prevent the problem in the first place, it's 1 partition only, on a levano workstation m82 with UEFI and a 100mb system reserved partition. Windows Boot Manager screen and states: Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1.Insert your Windows installation disc and restart your computer. 2.Choose your language settings, and then click "Next." 3.Click "Repair you computer." If you do not have this disc, contact your system administrator or computer manufacturer for assistance. Status: 0xc000000e

  • How do I determine if an unbootable copy of Windows is a 64-bit or 32-bit installation?

    - by svnpenn
    I need to reinstall Windows on a laptop. I have the product key (its on the laptop), and I know it is Windows 7 Home Premium. I need a way to determine if 64-bit or 32-bit Windows is installed, so that I can download the correct one from Microsoft. The computer is messed up so I do not have access to Windows to check it with systeminfo. I took out the hard drive and hooked it to another computer, but when I run systeminfo it just gives information for the host computer, I did not see a way to change this.

  • Network location is not on the Domain

    - by Kyle Brandt
    I have a computer joined to the domain, but it doesn't view the network "location" as being part of the domain. I have tried removing and rejoining the domain and this doesn't help: Other computers in the same network don't have this problem. I have also tried several different icons, including both the train and the airplane which doesn't seem to make a difference. At least using nslookup, the server seems to have connectivity with the DCs in the same site. There also seem to be some errors that suggest a NULL domain: Computer: OR-WEB05.ds.stackexchange.com Description: NtpClient was unable to set a domain peer to use as a time source because of failure in establishing a trust relationship between this computer and the '' domain in order to securely synchronize time. NtpClient will try again in 3473457 minutes and double the reattempt interval thereafter. The error was: The trust relationship between this workstation and the primary domain failed. (0x800706FD)

  • MS 2008 R2 Drops Remote Desktop Sessions in 10 seconds or less every time

    - by mike42
    I'm adding a new 64-bit server to our domain. Everything seems fine except when accessing the machine using remote desktop, after a few seconds the connection is lost. The error message is "This computer can't connect to the remote computer." "Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator." A similar result with Telnet on port 3389. I am able to connect but if I hit a key the connection to host lost. The event log shows the successful login. No errors. Any ideas?

  • Install Windows XP without disk

    - by Pearsonartphoto
    So, my kid's computer has Windows XP, with no disks. I'm pretty sure it has some viruses on the computer, of the type that don't seem to come out despite trying multiple anti-viral programs on it. I'm ready to just format it and start over again. I have a license sticker on the box, but no media to install it. I strongly suspect the license is OEM, but I don't have any proof. What suggestions would you have? I should say, the computer originally belonged to a business, is probably 6 years old, and I am willing to pay a small charge if required. I don't want to change the OS installed either.

  • How to Cut Search Engine Optimization Cost Down For Backlink Building?

    How much do you spend to get your high backlinks? I am guessing a good amount if you are paying a service to do it for you, or if you are buying backlink packets made by other people and paying a monthly fee. You can cut your search engine optimization cost greatly with some easy to use software, and even outsource the work for much cheaper than other SEO services.

    - by user88360
    I'm thinking on buying the Lenovo USB 3.0 Dock and use it with Ubuntu and Unity, but I haven't found information regarding if Ubuntu already has built-in drivers for it.

Thanks.

  • How to Get Your Site Indexed Quickly

    Most of the SEO experts advise to buy an existing domain or website. There are lots of age benefits of these old websites. However, buying an existing domain is not always an option. Many times you have to start afresh with a new domain. If you don't know about site indexing, Google may take weeks to index your website.

  • Weird internet connection issue on Ubuntu 14.04

    - by user287876
    I have an old Gateway PC with Windows 7 installed alongside the original (XP, I think?). A while ago my friend walked me through and helped me install Ubuntu 14.04 alongside the others because my Win7 was having issues with the display driver (it would unexpectedly crash while trying to watch videos on YouTube or other places). And I can't update it because the original computer settings are for XP or something, not Win7. :( We recently switched from AT&T U-Verse to Comcast. I would have stayed with Ethernet, but somehow the adapter I have wouldn't connect to Comcast's thing during their installation. So I was given a wireless USB adapter. It worked fine, up until the last few days. It's not a problem on Win7 (using it right now). Connection's strong, things load. On Ubuntu though, it SAYS it connects even before I login to my account, but when I login and bring up Firefox, it will load the homepage, and maybe one or two other pages I venture to before suddenly just... endlessly trying to load the page. I would normally go in and manually select 'disconnect' from the connections options menu to refresh/restart it like I've done a few times already. But lately, it won't respond, and then a little while later an error message comes up saying the request timed out/failed. Restarting my computer doesn't help it. The other weird thing is that I've noticed the signal (when it's actually working properly before the last few days) is comparitively weaker than when I'm on Win7. But my location doesn't change. It's the same computer, same connection.

  • One motherboard crashed. Changed and wants to crash again

    - by CoachNono
    My computer started to freeze randomly. I was pretty sure it was the hard drive that was starting to fail. Before I could change it, the motherboard was completely dead. I bought the same one and reinstall it. Everything went working well until my computer started to freeze again and doing the same problem has before. I don't want my motherboard to burn again and I'm really wondering what can be the problem... Could it be the power supply or the video cards that burned the motherboard ? I tested the voltages of the power supply and they seemed fine... The computer worked as is for four years... Here are the specs: ASUS P5N-D Motherboard LGA 775 NVIDIA 750i SLI Intel Q6600 2X EN9600GT 512mb 650w Corsair

  • Can I wake up PC/laptop on remote printing request?

    - by dzieciou
    I have an old Epson printer that does not have network adapter, only a USB socket. I have also a computer with network card. I could combine them to put this printer in my local network, but then I would need to keep the computer always up and running. That's definitely not economic. Is there a way to wake up computer when printing request arrives? Something like Wake-on-LAN? Or I am forced to use additional hardware?
