• Which PSU should one chose? The biggest is the best?

  - by Shiki

  I'm fully aware of PSU's "Active PFC" and that they won't consume the written W all the time. (Makes sense). But now I'm before a PSU replacement (Guys: NEVER buy a Chieftec. Seriously.) The question is: If one can get a bigger one (in my case 750W and 650W) ... should that person go for the bigger one ? (The difference in price is not much). No, I don't think I'll soon use all that much. (Please help (if you want of course) to make the question more generic if the question is really not OK in this form. I've been wondering about this for a time already. In my case it would be XFX Black Edition Silver 750W and 650W) (Basically about "which one" I would go with XFX/Antec/something which comes with industry qualified parts. Like Duracell but in a PSU. :) But the performance is a different thing.)

• Mapped network drive missing from My Computer and Explorer

  - by matt wilkie

  On a Windows XP Pro SP3 machine one network drive refuses to show up in My Computer or Explorer. The missing drive letter is G:, if that matters. Other mappings work fine. Other profiles one the same machine have no problem seeing G:. I can access the G: just fine typing it into the address bar or in CMD shell. I've used TweakUI to toggle hide/show G: with no difference. TweakUI says G: should be visible. I've logged off,on between toggles to make sure the settings are taking effect. I've looked at reg key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] and made sure it's zero'd.ref We've limped along with this broken setup for some time, just working around it, but some applications do not allow typing in a path when choosing a place to save files and it's reached the point where it's intolerable. So, anyone have any idea why XP won't show this drive letter? or how to fix it?

• Replace gvimext.dll in Windows 8

  - by Leftium

  How can I get the "Edit with ... using tabs" functionality in gVim on Windows 8 (64-bit)? I'd like to swap out gVim's stock gvimext.dll for one that adds an "Edit with ... using tabs" option to Explorer's right-click context menu. On Windows 7 (64-bit) I used to be able to download the DLL and swap it in by following these instructions. However, I can't get it to work in Windows 8. The stock installation's context menu (sans "... using tabs") works fine (without a restart) ...but after replacing the DLL the gVim context menu options disappear and the gvimext.dll no longer seems to even load. (Windows 8 was restarted) if I again replace gvimext.dll with a backup of the stock DLL, the context menu options remain missing and the DLL still seems to fail to load (Windows 8 was restarted, again) If I re-install gVim, the context menu items return (even without a restart) What is the difference here between Windows 7 (where swapping DLL's works) and Windows 8 (where swapping DLL's fails)?

• Remove Duplicate Messages from Maildir

  - by Joseph Holsten

  I've got a bunch of duplicate messages in my IMAP server's Maildir. What's the best way to remove them? Some relevant points: Shared Message-ID is usually a good enough definition of duplicate. A tiny script that removes all but one of the duplicate messages would work. Sometimes it's necessary to find duplicates based on shared message bodies. What's a reasonable definition of shared here? Bitwise equivalent? What about weird differences in line wrapping, escaping, character encoding? Sometimes there's some meaningful difference between 'duplicate' messages. What's the best way to review the differences in sets of 'duplicate' messages? Diffs?

• SSH automatic logon works for one user but not the other

  - by tinmaru

  I want to enable automatic ssh login using the .ssh/config file for my git user. Here is my .ssh/config file: Host test HostName myserver.net User test IdentityFile ~/.ssh/id_rsa Host git HostName myserver.net User git IdentityFile ~/.ssh/id_rsa It works for my test user but not for my git user so my global SSH configuration is correct. The configuration are exactly the same as far as I know. It used to work with git user but I'm unable what change has broken the automatic logon. When I type: ssh -v git I get the following log: ... debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey Offering RSA public key: /Users/mylocalusername/.ssh/id_rsa debug1: Authentications that can continue: publickey,password debug1: Next authentication method: password [email protected]'s password: _ Does anyone know what could be a possible difference

• Low FPS in some games, but hardware not fully used

  - by Mario De Schaepmeester

  I just did a little funny experiment in the game/sim "Train Simulator 2013". I normally have good FPS in it (around 30) at full settings. What I did was make a really, really long train so that the calculations the sim needed to make were enormous (the sim is quite realistic, it takes all things into account like speed/acceleration, G-forces, comfort levels, possible wheel slip and many more, and most of those things on each carriage seperately). This resulted in only 14FPS as reported by the game, but it felt more like 8FPS or so. I have a Logitech G15 keyboard which has an LCD, and it allows me to monitor CPU/RAM and video card load on it. The strange thing is, all CPU cores were busy, but the total load was only about 60% maximum at all times. The video card was only on 30% load (possibly an important note, the memory was full, which is however not unusual for the game in question). The RAM had plenty of room and there weren't many operations as it didn't grow or shrink much. I just have the feeling that the game would run smoother if it used more of my hardware power. Why is it not doing so? I had the same in another game, The Elder Scrolls: Morrowind when using more than 100 mods (that all use scripting) and a few high res texture mods, + a full-on graphics improvement program. The engine is very old (2003), and so I thought this might be the cause (not being optimised for multithreading). I had thought of possible causes, like: The operating system doesn't let the games use all the resources. It doesn't make use of multi-threading appropriately. To eliminate the former, I tried a CPU stress tool and that got 100% CPU juice as I let it run, so the OS is not the problem. I gave its thread the "higher" priority though. My actual question In both games, I did things the engine was not really built to do or support. Can those games' framerate be limited cause of their own engine not being able to cope? What is the real reason and more importantly, can I help it? And in any case, could something actually be wrong with my hardware? It's all reasonably new, a couple of months, and I (almost) never experience any other trouble. Modern and much more demanding games work absolutely fine. Specs CPU: AMD Phenom II 965 X4 @ 3.4gHz RAM: 8GB of DDR3 RAM Video: MSI GTX560 (nVidia chip) with 1GB of GDDR5 memory OS: Windows 7 Ultimate 64 bit Nothing overclocked.

• Windows equivalent for Linux "screen" or another alternative?

  - by Ubha

  Hello all! I'm on the lookout for a method to control programs in a Windows environment. I would prefer it to be a bit similar to the Linux software "screen". The reason of my search is that I need to start a program (on Windows) with an identifier, so I later would be able to close that specific program, without closing anything else - even though the actual program (.exe file) is running multiple times. So is there anyway I can "name" it? I'm using the following on Linux now: $ screen <params> <id> ./softwareprogram And then I know I can always find it with it's ID :) It's an external program which is closing or starting a 3rd party program. My program is written in C++, if that does any difference. Thanks :)

• Can an UPS be too powerful?

  - by Andy

  Our old network admin bought the top range UPS a few months ago but never came around to setting it up and is no longer with the company. Now the old UPS broke down and needs to be replaced, but an external company that did an audit said that that UPS won't work. Now we are no hardware specialists, but the difference in specs is a higher output from 5A to 8.8A meaning a higher output. But isn't the UPS supposed to give the server the required output anyway? This 'independent' audit does sell its own hardware including UPSes so I'm not sure how much bias they have. Is there a reason why we can't replace the old broken UPS with the new more powerful one? Is there a way we can check to see if the UPS works with our server? ok, i wrote down the numbers again, the Volts and Amps are what are on the back (where you connect up the plugs which seem diffrent from on the front label.) old one APC SmartUPS 1500 220-240V -- 6.8A new one Dell UPS 1920W 250V -- 10A

• Whats the best way to deal with backups for my php/mysql application

  - by spirytus

  I'm creating php application for my client and now thinking what would be the best way to do backups, automatically if possible? I don't have much experience in this area and in case something goes wrong, or if I need to migrate, I would like to have fast way of getting it all back online. I understand "something goes wrong" is a very wide term, but lets say that someone hacks my site and wipes out database and all the files. My app. is written in php/mysql and I got access to cpanel (hosted with justhost.com if that makes any difference :). I used Joomla and it has JoomlaPack that does complete backup almost automatically and in case site fails, its easy to revert, or migrate if necessary. Is there anything like that for my configuration that would make reverting/migration, easy?

• emacs starting maximised

  - by Seamus

  I want a keyboard shortcut to open emacs in a maximised window. I tried emacs --fullscreen, but that is full screen rather than maximised window... That is, the emacs window covers ubuntu menu bars. emacs -fw gets a full width window and emacs -fh gets a full height window, but if you put both options, it only reads the second one. At the moment, I just have another keyboard shortcut for maximising a window. Is there a way to get emacs to start maximised? Ubuntu 9.10, emacs 22, if that makes a difference.

• How to properly set CPU Units for OpenVz VEs

  - by gucki

  According to all the sources I read (openvz wiki, various mailinglists, forums, ..) the values of the cpuunits settings are relative to each other. So when all are equal and the system is busy, all receive the same cpu share. But something still puzzles me with that: why is there a tool "vzcpucheck" which shows "the power of the node/ host": Current CPU utilization: 18000 Power of the node: 880001 Why is there (do I need) an absolute number when all settings are only relative? Shouldn't those two settings result in exactly the same? ve1: 1 ve2: 1 ve3: 1 = 3 ve1: 293334 ve1: 293334 ve1: 293334 = 880001 (power of the node) What's the difference?

• Why do some actions not work with Remote Desktop?

  - by Holgerwa

  I usually connect to other PCs in the same building using Remote Desktop, which works great. For some reason, some actions cannot be performed through Remote Desktop. These are, for example: Installation of certain software Accessing the directory of a DVD (that is inserted at the remote computers drive) several other tasks that just "don't react or start", unless you do the same thing without RDP All these actions work with any other remote access tool, like VNC, Teamviewer, LogMeIn, etc. My question is: What is the difference when I use a computer through RDP instead of directly? Is there a list of prohibited actions available so that one could know upfront if something can be done with RDP or not?

• Drupal7 doesn't detect MySQL on CentOS, but Wordpress3 does?

  - by jyaworski

  Hey guys. I'm running CentOS 5.5 here with Apache2, PHP5, and MySQL 5. My wordpress install on the same system runs perfectly, but the drupal7 install script only detects SQLite. The mysql module is enabled in php.ini, so that isn't the problem. Do you think it could be something with Drupal 7, or my PHP install? I tested it on localhost (I'm essentially running ArchLinux with Apache) and it installs just fine. I don't see a difference between my local php.ini and my server php.ini. I get this when accessing install.php on the server. SQLite The type of database your Drupal data will be stored in. Your PHP configuration only supports a single database type, so it has been automatically selected. Edit: The mysql PDO module is installed already.

• Folder vs File Folder - Can I create a folder from the command line?

  - by Tim Gradwell

  If I create a shortcut to a folder and drag the shortcut onto the start menu, then the shortcut on the start menu behaves just like any other shortcut - click it to open the folder in explorer. However, if I drag the folder onto the start menu, then it expands in-situ. If I then copy this shortcut(?) into another location on my machine and compare it to other files/folders, its type appears as "Folder" as opposed to "File Folder" (which is what I get when I choose File-New-Folder. What's the difference between these two types of folder? Can I create one of these folders without dragging onto the start menu? Thanks

• Windows 7 Install command prompt can't access the C drive

  - by theouteredge

  I'm trying to create a new Windows 7 Professional VHD which I can dual boot to, following Scott Hanselman's guide to creating a bootable VHD. When I get to the command prompt in the Windows 7 installation and try to create a VHD or select/attach a pre-created VHD file I get an error saying that diskpart can't find the path specified. If I try and switch to the c drive using cd c: I see c:\ x:\something\> I already have a Windows 7 Ultimate install and my C drive is an SSD – if that makes a difference.

• tmux -- any way to enable scrolling, but not selection?

  - by gatoatigrado

  I like that when mode-mouse is on in tmux, I can scroll through the buffer, but I don't like that I can't copy stuff to my OS clipboard by selecting it (as when tmux is disabled). Question: Is there any way to enable mouse scrolling, but not selection? I'm using KDE's konsole, if it matters. I've tried setting, set -g mouse-select-pane off set -g mouse-select-window off but no luck -- the only difference seems to be whether mode-mouse is on (tmux captures scrolling and selection) or off (tmux captures neither scrolling nor selection).

• IIS wont run a BAT File

  - by Ye Ol Developer

  The problem we have run into is as follows. We have an ASP.NET WebService which runs under IIS7. The code in the WebService works 100%, however when the WebService tries to run a .BAT file, nothing happens. Nothing at all, the code doesn't crash, the server doesn't warn us about anything, nothing at all. We have tried setting the User Permissions, we have attempted difference ways of running the BAT, we have tried playing around with the registry, cmd.exe has full rights as well. We are now quite stumped as of what to do, any help would be appreciated.

• Mediawiki create user error after migration

  - by ing0

  So I had a mediawiki installed on windows with MySQL (running on AWS RDS). I've since moved it to a debian server for various reasons, but I think I've messed up the database because of the different versions of mediawiki I have used. The windows install was v 1.20alpha (58f390e). The new debian install is v 1.15.5-2squeeze4. I've tried to update debian but it doesn't find an update, so is this the latest squeeze version? Everything seems to work ok except adding users. It gives me a database error so I ran php maintenance/update.php which ran some stuff OK but didn't make a difference. I think I've not done the correct approach to this sort of move, does anyone know of a better way of doing it? I still have the old wiki running - but not used - on windows (using the same database) so I could always try this again.

• VPS showing low disk space despite there is nothing major on it

  - by SheoNarayyan

  Hello experts, On my VPS server I was trying to see the used disk space and when I open My Computer it shows 17.9 GB free out of 39.8 GB it means that 21.9 GB space is used. However, when I select all files and folders from C: and try to see the total size, it just count approximately 11 GB. The difference is around 10 GB. Where is this 10 GB going if I have not stored anything else here? I asked above question from my VPS provider and he responded below Check hidden files/system files/etc. This is default windows OS and its utilization and not specific to setup. If you want specifics of usage, you can go ahead and get in touch with Microsoft support team and they'll provide you with exact specification of the same. I am sure that Windows OS must not be taking up 10 GB space for hidden files and folders. My VPS has Windows Server 2008 R2 installed. Can anyone help me in this on who is right?

• How does the "Full Control" permission differ from manually giving all other permissions?

  - by Lord Torgamus

  On Windows Server 2003, and some other versions of Windows, the Properties > Security tab of a folder's or file's context menu provides "Allow" and "Deny" options for "Full Control," "Modify," "Read" and other permissions (graphic provided). After clicking "Full Control," all boxes in the column — except for "Special Permissions" — get automatically checked. What's the difference between checking "Full Control" and just checking all the other boxes individually? Are there hidden/advanced permissions toggled by "Full Control" that aren't listed in the main permissions window? Is "Full Control" just a convenience shortcut?

• Is there a time machine equivalent for windows that can back up network files?

  - by Jim Thio

  This question is similar to Does an equivalent of Time Machine exist for Windows?, with one difference: The files I want to back up are on a network drive. The computer on that network drive is running Windows XP. I want to back up data on Windows 7. How would I do so? I'd like something similar to Mac OS X' time machine. So copy of data every hour, day, week. Then thinning out, data gets deleted automatically as time goes by. For example, the data for last day is kept as hourly snapshots. For last week, as daily snapshots every day. And for last month as weekly snapshots. How can I achieve this?

• Can Visual Studio track the "size" or "severity" of my changes in TFS?

  - by anaximander

  I'm working on a sizeable project using VS2012 and TFS (also 2012, I think - I didn't set up the server). A lot of my recent tasks have required making very small changes to a lot of files, so I'm quite used to seeing a lot of items in my Pending Changes list. Is there a way to have VS and/or TFS track how much has been changed and let me know when the differences are becoming significant? Similarly, is there a way to quickly highlight where the major changes are when you get the latest version from TFS? It'd really help with tracking down where certain changes have been made without having to go through and compare every file - the difference highlighting tool might be nice, but when you have to use it on a dozen files to find the block you're looking for, you start to wonder if there's a faster way...

• Good Choice of Memory for Asus K52F-BBR5

  - by Christopher Painter

  I recently purchased an Asus K52F-BBR5 notebook. It's a basic laptop with an Intel P6100 CPU and Mobile Intel® HM55 Express Chipset. It came with 3GB of DDR3 SODIMM memory and I'd like to expand it to 8GB. I'm a little confused by DDR3 nomenclature and not up to date on my knowledge of chipsets. I'd like to make a good choice when selecting memory for it. Crucial's database suggests using either a PC3-8500 with CAS 7 or a PC3-10600 with a CAS of 9. Is the 8500 better because of it's CAS 7 or will my chipset run the memory async at a higher speed and get better performance? Which would be a better choice for my chipset and CPU? Price difference is negligble.
