• How to forward DHCP A record registration to another domain

  - by ServerUsedConfusion

  I'm currently at work and we're having some troubles. We want to create a new domain for our area, but the DHCP server is not in our control. The DHCP server lists DNS as testdomain.com, however we want to make a new domain called testdomain1.com. We've been thinking of fowarding the DNS from testdomain.com to testdomain1.com so that way DHCP doesn't have to be changed. Basically Client requests testdomain1.com DHCP says DNS is at testdomain.com testdomain.com tells client to go to testdomain1.com client registers in AD at testdomain1.com and adds it's A record to DNS at testdomain1.com

• Why my USB mouse get suspended after 3 seconds of inactivity?

  - by Vi.

  Mouse's bottom LED goes off after 3 seconds after connection and cursor movements and wheel stops. Pressing any button, reconnecting or resetting USB device resumes it for another 3 seconds (when resumed by pressing button, this event does no go to X). This happens when using any of USB ports. This mouse works well with other computer with Linux. It was working well before. Why can it happen? How to fix it? Update: It happens only if laptop is on battery. Answer: this is caused by powersaving done by laptop-mode-tools. To temporary turn off powersaving one can use for i in /sys/bus/usb/devices/*/power/control; do echo on > $i; done

• How can I guarantee a solvable Fifteen Puzzle shuffle?

  - by Codemiester

  I am making a 15 Puzzle game in C# that allows the user to enter a custom row and column value up to a maximum of a 10 x 10 puzzle. I am having problems with the shuffle method. I want to make it so the puzzle is always solvable by first creating a winning puzzle then shuffling the empty space. The problem is it is too inefficient to call every click event each time. I need a way to invoke the click event of a button adjacent to the empty space but not diagonal. I also use an invisible static button for the empty spot. The PuzzlePiece class inherits from Button. I am not too sure how to do this. Here is what I have: private void shuffleBoard() { //5 is just for test purposes for (int i = 0; i < 5; i++) { foreach (Control item in this.Controls) { if (item is PuzzlePiece) { ((PuzzlePiece)item).PerformClick(); } } } } void PuzzlePiece_Click(object sender, EventArgs e) { PuzzlePiece piece = (PuzzlePiece)sender; if (piece.Right == puzzleForm.emptyPiece.Left && piece.Top == puzzleForm.emptyPiece.Top) { movePiece(piece); } else if (piece.Left == puzzleForm.emptyPiece.Right && piece.Top == puzzleForm.emptyPiece.Top) { movePiece(piece); } else if (piece.Top == puzzleForm.emptyPiece.Bottom && piece.Left == puzzleForm.emptyPiece.Left) { movePiece(piece); } else if (piece.Bottom == puzzleForm.emptyPiece.Top && piece.Left == puzzleForm.emptyPiece.Left) { movePiece(piece); } }

• How can I convince my boss that ANSI C is inadequate for our new project?

  - by justifiably cowardly

  A few months ago, we started developing an app to control an in-house developed test equipment and record a set of measurements. It should have a simple UI, and would likely require threads due to the continuous recording that must take place. This application will be used for a few years, and shall be maintained by a number of computer science students during this period. Our boss graduated some 30 years ago (not to be taken as an offense; I have more than half that time on my back too) and has mandated that we develop this application in ANSI C. The rationale is that he is the only one that will be around the entire time, and therefore he must be able to understand what we are doing. He also ruled that we should use no abstract data types; he even gave us a list with the name of the global variables (sigh) he wants us to use. I actually tried that approach for a while, but it was really slowing me down to make sure that all pointer operations were safe and all strings had the correct size. Additionally, the number of lines of code that actually related to the problem in hand was a only small fraction of our code base. After a few days, I scrapped the entire thing and started anew using C#. Our boss has already seen the program running and he likes the way it works, but he doesn't know that it's written in another language. Next week the two of us will meet to go over the source code, so that he "will know how to maintain it". I am sort of scared, and I would like to hear from you guys what arguments I could use to support my decision. Cowardly yours,

• Using Dropbox API instead of a FTP server for backing up DB/Source in your application.

  - by Somebody still uses you MS-DOS

  This is a small aplication scenario. Usually, when you have to do some backups of source code/database on your server, you use a second ftp server, a cronjob to tar.gz your db dumps and source files, and send this file to your ftp server from your application server. Dropbox created an API to use it's infrastrucutre. Since they provide 2gb for free accounts, I thought about being able to upload to it instead of a ftp server. So, if you do some freelance work, you can create a free account for each client and use this approach, maybe encrypting the files you send. You even gain a revision for each sent file, like a revison control system, for free, from the last 30 days. What do you think of this approach? Is it possible? And, more importantly: what are the security risks involved? (That's why I'm asking this on serverfault, since this POV from sysadmins will be more accurate). Thanks!

• How to prevent computer from automatically sleeping and/or hibernating?

  - by mehaase

  I'm running Ubuntu 12.04, and my laptop* won't wake from sleep/suspend/hibernate. (Is sleep the same thing as suspend?) I'm not even sure which of these things it's doing. When I am done working for the day, I lock my screen (Control-Alt-L). When I come back the next day, the screen is in power saving mode, and no amount of typing or clicking (on the usb keyboard/mouse or the builtin keyboard/trackpad) nor tapping the power button will bring it back to life. The only way I can get my machine to work is to hold down the power button until it shuts off, then press the power button again to turn it back on. Obviously, anything I had open from the previous day is pretty much gone -- in particular, my VMs all get rudely shut down without any warning. This is driving me INSANE. I spend the first hour of every work day trying to figure out how to get my computer to stop locking up over night. What I've tried: Editing the org.freedesktop.upower.policy to disable suspend and hibernate. Setting power management options in "Power" section of "System Settings". Looking at all power management options in the BIOS (none appear to be relevant to sleep/suspend/hibernate). Reading every forum post/askubuntu post that I can find that's even tangentially related to the subject. My question: how to disable the automatic sleep and/or hibernate (and/or anything similar) in Ubuntu 12.04. I don't care if it's still possible to sleep/suspend/hibernate/whatever by pushing buttons or running some command or reciting led zeppelin lyrics backwards. I just want my laptop to be ready for work in the morning. *The laptop is a Dell Latitude something or other. I don't want to get too specific because I've seen a lot of similar questions get closed for being too specific. I think my question is generic enough to stand -- it's a question about the latest, stable version of Ubuntu.

• Release Notes for 3/2/2012

  Here are the notes for today’s release: Added a progress indicator when saving issues. Added support for viewing CodePlex RSS feeds in Chrome. Deployed several bug fixes: Fixed an issue where the back button on Internet Explorer was not working as intended when browsing code. Fixed an issue where long commit comments would push the source control info box outside of the boundaries of the page. Fixed an issue where Internet Explorer users were not able to widen the frame of the source code browser until a file was selected. Fixed an issue where opening a source code file directly from a URL in Internet Explorer would cause the source code tree to be collapsed. Fixed an issue where adding a code snippet with long lines of text to a discussion thread using Internet Explorer would needlessly display a vertical scrollbar, limiting the amount of code visible. Fixed an issue where tabbing through some links would render them invisible. We deprecated support for embedding PreEmptive analytics statistics on the project statistics page. If you’re interested in collecting and reporting your own statistics, PreEmptive’s RunTime Intelligence Endpoint Starter Kit offers a good starting point for capturing data.

• Triple head DVI KVM

  - by cat pants

  I am trying to run a Linux desktop and Windows desktop simultaneously with a KVM for maximum productivity. Also running three monitors. I need a KVM that can do 3x DVI @ 1920x1080 + 2x usb (mouse and keyboard) + toslink for two machines. What would you suggest? I ask on here because I have searched quite a bit and have yet to find a KVM with these requirements. (I would be open to something like modifying 3x regular KVMs to control them with one button or similar) Thanks! (I tried posting this question earlier, but it was closed as being "not related to computer hardware or software" ... is a KVM not related to computer hardware or software? I'm pretty sure it is. kvm-switch has been tagged 100 times on here for example.)

• PHP hosting some info required [closed]

  - by mtk

  I have recently given a control of newly bought hosting space and the domain account. There is a technical team from the hosting site to help out with problems, but that is a long process, i.e. log a ticket, wait for a long time, and I don't get the correct answer in the first shot. I was wondering, if anyone has any helpful guide and how one must go with hosting a site. Any info that must be know w.r.t to cpanel? Any other useful stuff if any one has, or could point me to ? Just to give a few difficulties: The same php code working well on local machine, giving error on remote as "File not found". The file is present indeed as I have ftp'ed all the files correctly. session_start error are outputted to html page with warning "Header already sent". and many more technical things, that work well on local but not on actual hosting server. So, if anyone has any helpful stuff in this reference, as to what all changes are required or what a programmer must be aware from a hosting perspective, please let me know. Note I am hosting a PHP site with mysql db, on a shared environment.

• Tool to create unscaled call-out from a thumbnail image?

  - by Mal Ross

  I'm creating an online tutorial for some software and need to include screenshots. In particular, I want to highlight the position and appearance of a given control in a large screen. Given that I haven't got the space to show the screen at full resolution (at least, not alongside the tutorial text), I figured I would use a kind of call-out from a thumbnail. Here's my poor first effort, made in Paint.NET: Given how long this took me to craft, I'd really like to find a tool to speed things up (and make them look a little more professional!). Preferably a free one, too - or one that has a downloadable trial. The exact style it produces isn't that important, provided it achieves the desired effect. Can anyone help me out? Thanks, Mal. P.S. I'm using Windows Vista.

• Resolution is Being Stupid. Help me?

  - by One Terrorist

  I'm having trouble with a new computer I bought a few days ago. I have come to the conclusion that the resolution of the screen is too small, at the moment it is 1024x768 and I think it should be 1280x960, due to a message given at the resolution tab of the control panel. It states: (!) If your resolution is below 1280x960, some items on the screen may not fit on the screen. The computer is an Asus A54H and runs 64-bit operating system with Windows 7 Home Premium. This link has a screenshot of the screen at the moment, the icons and font are too big and are a little stretched. Thank you in advance!

• No audio driver for ECS 7050-M v1.0a for Windows 7?

  - by NudeRaider

  I have an Elitegroup 7050-M v1.0a motherboard and I've used the Realtek HD audio driver it came with for years under Windows XP. There was a nice mixer panel, an equalizer and sound profiles that added effects. All of these menus are gone now that I've moved on to Windows 7 64 Bit. All I have is the basic settings under system control - sound, but they are not nearly as detailed. To clarify: Sound works, but the advanced settings I got when using older OS's are gone. Older drivers don't seem to work under Win7 and I can't find one for Win7. So how can I fully utilize the capabilities of my HD sound chip under Win7?

• Web hosting deciding to pay for hosting or host your own?

  - by pllee

  Is there a guide out there on how to choose when to pay for web hosting vs. hosting your own? Assuming that root access is a must I would like to compare things like cost, scalability and personal stress. Here is what I could come up with. Paying for web hosting: Benefits: Much cheaper for a small scale. I assume anything under $50 a month would be cheaper than paying for the bandwidth of hosting. No stress in dealing with power outages, server restarts or internet going down. For the most part less busy work involved with setting up. Negatives: Cost goes way up when higher specs are needed (for example monthly cost triples with ability to use 8gb of ram that you can buy for $90 ). This means you have to target a particular ram usage and monitor so your instance stays within the threshold. root access for the most part is a premium. You may get tied into a vendor specific deployment process. Hosting on own : Positives: 100% control of specs and software. When you get past paying for the bandwidth you get much more bang for your buck by building your own machine. Negatives: Doesn't make financial sense if bandwidth costs are more than web hosting costs. Having to deal with power outages, server restarts or internet going down. I think the best of both worlds would be if there was a place that dealt with bandwidth, power outages and server restarts but you provided your own server. Kind of like a 24 hour day care for a server. Does anything like that exist?

• Is it possible to create a full "encrypted worried about privacy" VPS, but still being externally us

  - by Somebody still uses you MS-DOS

  I've been reading a lot of things about privacy, "being in control of your data" and everything, and now a project called diaspora* is trying to be an OSS Facebook alternative. Fact is: you still have to use a server. Even if you use a VPS somewhere, they still have access do your data, so diaspora* isn't that protective shell people are looking for absolute power over your data unless you create a server on your basement. My question is: is it possible to create a really encrypted usable server using a VPS? From database to source files? If not, what it can be "obfuscated" or encrypted? (And just a mention, not really my question, do you think is diaspora* really possible to be made?) (I know if you really want privacy you shouldn't be even using these services and being social, but I'm asking if it's possible to at least avoid companies using your data)

• In-House DropBox

  - by beardedlinuxgeek

  Dropbox is perfect, but as a company, no one can host anything worthwhile on servers that we don't control. So I've been tasked with coming up with a Dropbox alternative, something in house. GlusterFS is nice, but no offline access. SparkleShare uses Git which isn't great for large files. It also doesn't have windows ports. Any other options? If I were to roll out my own from scratch, what do you think the based way to go about doing this would be?

• How do I display the Java console?

  - by Brian Knoblauch

  I'm aware of the fact that you can set it to "show" in the Java control panel, but that's not what I'm asking about. I'm curious about the other options... "Do not start" is pretty straightforward, but what about "Hide"? That would seem to imply that it is indeed running. If so, how can I make it show on demand from the hidden state? Reason: It's annoying to have it open ALL the time, hoping there's a way to (preferably via keystroke) bring it from "hidden" to "shown" state for occasional debugging.

• Manage 2 displays remotely

  - by neurino

  I have a pc with a nVidia Quadro graphic card. The card has 2 DisplayPort outs where 2 40" Full HD TV are connected. I need to run 2 separate fullscreen videos, one each display. The problem is displays are far from the pc station and I cannot control them from there. I tried with a remote desktop connection but when I connect screen 1 shows login and screen 2 simply blackens (I'm logged off). The pc, an HP, also has his native graphics card still installed it would be nice if I could connect there a 15" monitor with the desktop on and use the TVs only as secondary where I can send fullscreen videos. Any clue?

• Is there a multi-user Remote Desktop app for Mac OS X?

  - by Peter Walke

  Is there a remote desktop app for the Mac that allows multiple people to be remoted in at the same time, similar to RDP in Windows? I've used VNC, but that only allows one person to control the computer. For some background: I'd like to set up a mac that many users can RDP into from PC's to do XCode development. I did some searching and didn't find anything, so I'm assuming it's just not possible, but I want to confirm. Thanks. Update: Thanks to a link in one of the answers, I found a reasonable solution: AquaConnect

• What is an Automated way to Access a Virtual Machine's Webserver from its Host Machine? [closed]

  - by Jonnybojangles

  As a Web-Developer what is the most efficient (automated) way to connect to a Virtual Machine (VM) running a development webserver from it’s Host Machine (the machine running the VM) when you do not have control over the networks (home, Startbucks, work, etc) you are connected to? Currently I start my VM (a VirtualBox VM running CentOS), run ifconfig to determine the VM’s current IP. I then take that IP and map it my Host machine’s host file so that I can access the VM’s webserver from the Host. I feel that this is not an efficient way to connect to my VM’s webserver because each time I connect to a new network (a few times a day) I need to repeat the IP look up and host file update, and sometimes restart the VM's network service.

• Files apperaring/disappering from folder on share

  - by rheitzman

  Windows Server 2008 R2 I have a folder H:\temp\folderName where H: is a file share under ADS on the server. I have "Full Control" permission on the folder. I can open the folder and see a file and/or a folder that is supposed there. If I try to drag/drop or Copy/Paste the file I get an error "Could not find this item. This is no longer in ...." But I can still see the file. Similar issue occur at command prompt. I cannot delete the folder. Delete actions run w/o error but the folder is still present. I was able to rename the folder. My guess is there are some cross link issues. Or? Does anyone recognize this syndrome? What is the proper next step to verify the file share?

• SCCM - How to make new deployed applications appear in Software Center faster?

  - by icehac

  I am trying to make the process between SCCM deployments and the Software Center (configmgr) faster, if not seamless. Right now, applications generally take about 1-2 hours to populate properly. However, by going to the "Configuration Manager" under the Windows Control Panel, there is an "Actions" tab. Generally 5 minutes after running these "Actions", the software will populate inside the Software Center. The downside of this is the user interaction with the "Actions" pane...I can't have a user going through this process when they request a new application that needs to be deployed through SCCM. I have have played around with using "net stop ccmexec" and "net start ccmexec" to manually run all of these "Actions" on the start command, but it feels a bit archaic. Does anyone have any suggestions how to speed this process up? I feel there is something simple I am missing.

• Is there any way to make an external monitor the primary under Boot Camp?

  - by mmc

  This may be a general problem for all Windows XP portables, I don't know, I don't have a dedicated Windows portable. I'm running a MacBookPro Unibody (so it's using the Nvidia 9600M chip under Windows XP SP2). Is there any way to get my external monitor to be the "main"? Even when I use the Nvidia Control Panel to move the task bar to my external monitor, games still refuse to run on anything other than the internal monitor. (In full screen mode, of course, if it's in a window, I can drag it to the other screen, no problem) I know I'm missing something elementary here.

• System restore with no mouse or keyboard.

  - by user62371

  I accidentally installed some USB drivers to my Windows 7 system, they were the wrong ones and now my keyboard and mouse won't work. A system restore would get rid of them, but obviously I can't control my computer to make that happen. Keyboard and mouse still work before windows has loaded, in the BIOS and boot system, so can I do anything from there? I've already tried booting into another OS, accessing my windows filesystem and deleting the Program Files entry, but it didnt work so they must go deeper than that. Or could i launch it from a remote machine? I've got some VNC server insalled so if i could get that running that could work.
