• How to disable screens turn off Windows 8.1

  - by Warpzit

  So recently my computer started turning my screen monitors off after a while without activity, if I move the mouse or hit the keyboard they turn back on. I just want them to stay on. My System is windows 8.1 64 bit, I have 2 screens with mini display port and 1 television with hdmi which often is in regular television mode when this issue happens. Now before you jump to conclusions this is what I've tryed: Disabled screen saver Power saving settings to high with following set: Turn of the display: Never Put the computer to sleep: Never Turn off hard disk after: Settings: Never Sleep: Sleep after: Settings: Never Display: Turn off display after: Settings: Never Display: Enable adaptive brightness: Settings: Off Multimedia settings: When sharing media: Settings: Prevent idling to sleep. Any pointers that get me in the right direction will be greatly appreciated.

• Issues connecting VMWare VM to Windows 7 (host)

  - by MasterGberry

  I am on windows 7 trying to figure out why i cannot ping my computer or my VM from the other one, yet I am able to ping the router on both and other computers on the network. My desktop is running windows 7 64 bit and my vm is running CentOS 64 bit (which is what I use to test my web server stuff). At my school the VM has a dedicated IP and i don't have this issue, but I am home now and having issues trying to set this up behind my dumb router...I had already tried changing the VINC (i believe) to hide the vmnet1 and vmnet8 connections from the windows firewall and this seemed to have worked for like 5 minutes and then stopped... Any ideas? Thanks

• Use Amazon EC2 as a backup server

  - by MikeMurko

  I would like to use Amazon EC2 as an emergency backup database+web server in the event our primary host becomes unavailable. I feel like I wouldn't have trouble setting up a Windows instance, install SQL Server and get the web server up and running (would take a few hours, plus installing various libraries, our source code, etc). My question relates to pricing. If I simply "stop" the instance rather than "terminate" it, does that stop counting "instance-hours"? I would prefer not to terminate the instance and lose all that work I spent setting it up. If I must "terminate" in order to stop the billing - is it possible to make an image of the server after I have set it all up, then save that image somewhere (S3?) Is this something that people do regularly? Ideally this instance would just be waiting in the wings for an issue with our host, but costing us nothing except perhaps data storage costs.

• What data should I (can I) gather to prove a .net bug in third party software?

  - by gef05

  Our users are using a third-party system and every so often - a user might go all day without this happening, other days they may see it two or three times in seven hours - a red x will appear on screen rather than a button, field, or control. This is a .net system. Looking online I can see that this is a .net error. Problem is, our devs didn't write it, and the vendor wants proof that the problem resides with their system, not our PCs. What can we do to gather information on such an issue that would allow us to make our case to the vendor and get them to create a fix? I'm thinking of data to gather - anything from OS, memory. .net version installed etc. But I'd also like to know about error logging - if it's possible to log errors that occur in third-party systems.

• Grub not loading after Windows 8 Install

  - by RazorXsr

  My system was configured to dual boot Ubuntu 12.04.1 LTS and Windows 7. Today I got my hands on the MSDN release of Windows 8 and I installed it over my Windows 7. Now the computer just boots to Windows 8 directly without loading the GRUB screen. So I followed the steps as suggested in: https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows. Running this command: ls -l /dev/disk/by-label/ gives the following output: total 0 lrwxrwxrwx 1 root root 10 Sep 11 07:51 Entertainment -> ../../sda2 lrwxrwxrwx 1 root root 10 Sep 11 02:45 PENDRIVE -> ../../sdb1 Also fdisk -l command gives this as the output: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x1246aa23 Device Boot Start End Blocks Id System /dev/sda1 * 2048 319582199 159790076 7 HPFS/NTFS/exFAT /dev/sda2 319582208 602906623 141662208 7 HPFS/NTFS/exFAT /dev/sda3 602908672 625135615 11113472 83 Linux Disk /dev/sdb: 1939 MB, 1939865600 bytes 64 heads, 63 sectors/track, 939 cylinders, total 3788800 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc3072e18 Device Boot Start End Blocks Id System /dev/sdb1 * 2248 3788799 1893276 c W95 FAT32 (LBA) So I assume that I have to run this: sudo grub-install /dev/sda3 to get GRUB up and running. But I am getting this error: /usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?). Can anyone please guide me in the right direction? The current Ubuntu installation is far too customized to my needs to lose it to a boot manager issue! Any help is much appreciated!

• Error sysprepping Windows 8 Enterprise 90-day trial

  - by Philip

  I am using the Windows 8 Enterprise 90-day trial to evaluate the latest version of Windows for a private school. The way I work is that I use sysprep to prepare an generalized image, then I clone it to the school's computers. When I follow the instructions and try sysprep on my installation of Windows 8 in VirtualBox, sysprep thinks briefly and gives me an error message: Fatal error occurred while trying to sysprep the machine. Once I acknowledge it, sysprep closes. I checked the Windows Event Log, and there's nothing there that I could see. I also followed some instructions to cure this problem, but nothing changed. The error remains. My best guess is that the 90-day trial prohibits the use of sysprep, but I can't be sure. It might also be my use of VirtualBox, or who-knows-what. Has anyone had success with this, or encountered the same issue on real hardware?

• How can I get logrotate dateext to reflect the log date rather than the rotation date?

  - by Adam

  My Apache logrotate config looks like this: /var/log/http/*log { monthly dateext dateformat .%Y.%m [... rest stripped for brevity ...] } This works great, except that the date on the rotated filename is one period later than the period actually covered by the logs, for example error_log.2012.09 covers 2012-08-01 to 2012-08-31. I realize that there are other options for Apache (eg. cronolog), but I have a bunch of other logs that I also need to rotate, and logrotate is really exactly what I need apart from this one issue. Is there a way to get logrotate to use a date offset -- or, even better, figure out the previous time period -- when generating the rotated filename?

• Performance problems - Jira running on Ubuntu over VMware ESX 4.0 maxing out all 4 vCPUs.

  - by Jack T

  We are running Jira on a box under VMware ESX 4.0 and performance is vaiable to say the least. The physical box has 12 Gig RAM and 4x Xeon 2.26 GHz CPUs. vCentre is telling us the CPUs are not maxed out at any time, RAM is fine too. When we issue a request to the host it sometimes maxes out all 4 vCPUs. Sometimes it's quick, sometimes very very slow. There doesn't seem to be a pattern. Any ideas?

• How can I fix a desktop right click delay in Windows 7?

  - by Xm7X

  I am looking for information on how to properly troubleshoot a desktop right click delay in Windows 7 after 3rd party apps have been installed. I did find this program ShellMenuView. This will allow me to disable the context menu items of explorer. I can now use process of elimination to find the problem. Is this the best way to fix this issue? I would also like to avoid installing more apps to solve the problem. Can I go directly to the registry to fix this? Thanks

• How can I move a window that cannot be moved by mouse?

  - by Michael

  I have downloaded a version of Finale Notepad on Windows 7. When I first used it it functioned perfectly. Every time I opened it a popup asking me about downloading a different version would show up that I could just click out of. When the pop up appeared I was unable to quit out of the window or move it at all, but it posed no issue. Apparently, though, the last time I quit out of the program, the screen must have been dragged down below my taskbar. Now, I am unable to quit out of the popup when I reopen the program, meaning I can't access it at all. I tried restarting my computer, uninstalling the program, downloading different versions of the program, and even using alternate methods of moving it, such as Alt+Tab, but nothing works.

• HDDs randomly falling off raid

  - by michael

  I really need help on this it's Saturday long weekend.No customer service help:( .I recently build new server/light duty desktop.Main purpose is only file sharing.Raid configuration :Adaptec 6805 ,8x 3TB HDD WD Red,Intel RES2SV240 expander,Raid 6,set in Intel mobo DZ 77GA-70K.I upgraded firmwares, but I'm having strange problem. During Build Verify segment 7 got missing.I just reinsert drive into hot swap bay and it started to rebuild Array.After rebuild was done another segments 0 and 5 gone missing while build/verify.I reinserted drives and now I'm praying that raid is going to rebuild successfully from remaining 6 drives,because i already transfer some data on it(I know it was bad idea).I checked S.M.A.R.T on missing drives , it only says link failure and aborted commands on one of them.No Errors on HDDs.Connections and cables are good.I added 2 fans blowing on RAID controller because it was getting too hot, so I guess overheating shouldn't be issue.What can be possibly wrong? Thank you for help.

• colliding btRigidBody objects behave strangely when moving slowly

  - by Piku

  I'm trying to use Bullet Physics in my iOS game. The engine appears to be correctly compiled in that the demos work fine. In my game I have the player's ship and some enemy ships. They're defined as btRigidBody objects and btCollisionObjects and I'm using btSphereShapes for collision. At 'fast' speeds, collisions appear to happen sensibly - things collide and nothing goes 'weird'. If the speeds are very slow though and the player's ship touches a non-moving object the collision happens, but then the player's ship moves at incredible speed over the next few frames and appears a long distance from where it collided - completely out of proportion to the speed it was moving before impact. To move the things around I'm using setLinearVelocity() each frame, ticking the physics engine, then using getMotionState() to update the rendering code I have. Part of the issue might be I don't quite understand how to set the correct mass or what the best speeds are to use for anything. I'm mostly sticking numbers in and seeing what happens. Should I be using Bullet in this way, and are there any guidelines for deciding on the mass of objects? (am I right in assuming that in collisions heavier objects will force lighter objects to move more)

• Very Dark Windows 7 Screen

  - by user147521

  My Gateway laptop -Windows 7- screen became too dark a few days ago after I finished installing Windows automatic update. I can see nothing unless I use a flashlight. Windows login screen is the only bright screen for few seconds. What should I do to resolve this issue? I checked power-saving/ Power Options settings and rebooting in Safe Mode. I tried to lower the refresh rate but it did not allow me. The laptop adapter type is ATI Radeon Xpress series. I calibrated display color. I uninstalled and reinstalled the adapter. I tried to update the driver but the driver is up to-date. Any help would be appreciated.

• How to synchronize a whole Ubuntu?

  - by Avio

  I think that the time is ripe to have my whole Ubuntu synchronized just as my Dropbox folder is. Given that we are always talking about files and directories, what's the difference between my Documents folder and my /usr system directory? Almost none, except for their location. In fact, I think that there is just one big issue that prevents people to have their beloved installations mirrored wherever they go: symlinks. Dropbox, Google Drive, Ubuntu One, Sugarsync, Skydrive, none of these services support symlinking. This means that if I push a symlink in one of the synced folders, locally the symlink is kept as is, but remotely (in the cloud or on the other synced machines) the symlink is resolved to the actual file that was originally pointed to. This completely disrupts Linux installations, thus these services can't be used for this purpose. So the question is. Does anybody knows a way to achieve this? A whole Ubuntu, always synchronized with a remote running copy, but still locally stored on both disks? My best guess is that I could use NFS. But the main difference between Dropbox and NFS is that NFS is a remote filesystem that always forces to remotely access the files, while Dropbox pushes modifcations to local filesystems (and thus would perform better). I've also heard about NFS caching. Does anybody knows if this solution could approximate Dropbox in this sense? P.s. I know that /boot, /dev, /proc, /run, /tmp and device-specific mountpoints in /mnt and /media will have to be left out the sync mechanism. What I'm interested in is the principle. Can this be done with reasonable performance, having reasonable resources (e.g. ~ 1Mbps upload bandwidth and a public IP address)?

• Resolving Domainnames differently for different services

  - by mlaug

  Some time ago we had an issue with our network infrastructure and php with curl. Our Network infrastructure is fairly simple. LoadBalancer/Firewall = 5 servers The Domainname of our website is set to the ip of the Loadbalancer, of course. But calling curl from one of the servers did result in a timeout. It appears that a server could not call for its own domain it is serving. So we had to set the domains via /etc/hosts to the sever itself. But now We have implemented a Varnish in front of the Loadbalancer, which we want to automatically purge, once a change on a page happens. So now we need to call the domain www.example.com/url_to_purge. Sadly this call what be resolved to the server itself instead of the varnish, because of the /etc/hosts entries. So now I am wondering, if you could resolve domain names differently for different services :)

• Ubuntu 13.10. After login, no desktop displayed. Two Nvidia Graphics Cards, Four Monitors

  - by jmerkow

  I am working on an issue with my Ubuntu 13.10 installation. I am attempting to get 4 monitors up and running but I am having some trouble. So far, I installed and updated to the latest NVIDIA drivers (331.20). Initially X would not start (after installation) so I replaced my xorg.conf with xorg.conf.failsafe. This fixed that problem, but then I tried to enable the other 2 monitors (other video card) and xorg fails to start once again (after I login there is no desktop). I am fairly new to linux but I am not a complete beginner, but I'm not comfortable poking around too much on my own to troubleshoot yet.... lspci -nn | grep VGA: 03:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF110 [GeForce GTX 570 Rev. 2] [10de:1086] (rev a1) 05:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF110 [GeForce GTX 580] [10de:1080] (rev a1) It seems that the nvidia-settings tool does not result in a good xorg.conf file.

• FreeBSD Jail own network stack with vimage

• Windows 7 Incorrect Scaling

  - by Anonymous

  I ran into a problem the second after installing Windows 7 a few months ago, but it only affected a few applications at the time, so I ignored it. Now an increasing number of applications behave the same way and it's annoying. The DPI settings seem to have an issue as can be seen below: The same application should look like this: The DPI is set to 100% (I tried changing it but it had no effect). I think perhaps the Regional / Language settings have something to do with it but I can't turn it off to English only. Any ideas?

• Prevent specific applications from being run as administrator

  - by Unsigned

  Background Most installation toolkits have the ability to launch, automatically or otherwise, external programs after installation. This is often appears in the installer via such options as "Show readme", or "Start program". Issue The problem is, many of these installers are poorly coded, and do not drop permissions appropriately. For example, starting the application automatically, or opening the application's homepage in the browser, often results in launching the application or browser with the installer's Administrative privileges, or a "High" UAC integrity level! This has the potential to open up security breaches, by opening up the installed application, or a web page (and possibly browser add-ons), that are now running with elevated permissions. (This is the reason I strongly recommend never choosing auto-launch options when installing software.) Question The question is: Is there a way to prevent certain applications (such as a web browser) from ever being launched with Administrative privileges, i.e., an automatic drop-privilege?

• How does process of updating code with Continous Integration work?

  - by BleakCabalist

  I want to draw a model of process of updating the source code with the use of Continous Integration. The main issue is I don't really understand how it works when there are several programmers working on various aspects of the code at the same time. I can't visualize it in my mind. Here's what I know but I might be wrong: New code is sent to repository. Continous Integration server asks Version Control System if there is a new code in repository. If there is than CIS executes tests on the code. If tests show there are problems than CIS orders VCS to revert back to working wersion of the code and communicates it to programmer. If tests are passed positively it compiles the repository code and makes new build of a game? New build is made not after ever single change, but at the end of the day I believe? Are my assumptions above correct? If yes, does it also work when there are several programmers updating repository at once? Is this enough to draw a model of the process in your opinions or did I miss something? Also, what software would I need for above process? Can you guys give examples for CIS software and VCS software and whatever else I need? Does CIS software perform code tests or do I need another tool for that and integrate it with CIS? Is there a repository software?

• What's the best way to handle numerous recurring log entries in game loop?

  - by Kaa

  I have a custom logging system, use of which is scattered all over the engine and game. The system is linked to a "LogStore" that has an std::vector<string> logs[NUM_LOG_TYPES] - each vector corresponds with it's log type (info, error, debug, etc.). There's one extra std::vector that has "coordinates" to all log entries in the order they were received. Now, all the logging output is also displayed inside my development console in the game. The game console is handled by HTML-type GUI and therefore requires a new <p> element being added for each log output. My problem is that the log entries that are generated in the main loop each frame freeze the engine, because they continue to add elements to the in-game console, and if the console or guy generates a warning - that creates an infinite logging loop. I want to solve it by handling the recurring log entries in an elegant way that lets you know that something is critically wrong, but won't freeze the engine - like displaying the count of errors in the last 60 frames instead of displaying errors themselves. But how do you guys handle this? Does anyone know any nifty tricks to do this? I understand the question may sound vague, but if someone came across this type of issue I'm sure they would know exactly what's happening. Example problematic log entries: OpenGL warnings (I actually do check for errors every frame in many places) Really any prints anywhere in the main loop (may be debugging, may be warnings)
