• diagnose "corrupt file" problems

  - by Matthew

  My computer has been crashing the last couple weeks pretty regularly (at least once a day). A lot of times things I do will display a little notification in the bottom right saying something about a corrupt file. (I'm on Windows XP Pro Service Pack 3). When the computer does crash I get the "blue screen of death" usually. Some of the notifications also advise running the chkdsk utility. I cannot get it to successfully run. Using the command prompt (or even the "tools" menu after right clicking the drive and choosing properties), it will not run the utility (it says "do you want to schedule it to run next boot time" or whatever, which I confirm). The problem is that most of the time after restarting, it doesn't run at all. The few times it does run, it has an error (I can't remember the error right now, it at least says it's ntfs and such) and says disk checking will end. How can I get it to successfully run?

• SQL Server Replication Agent priority

  - by Wikser

  Every hour a server replicates SQL server data with some external web server. During this time, which takes about 2-5minutes, the database seriously slows down. Colleagues, which work with the front end applications of that on another terminal server, even regularly start complaining. The databases are also synchroniously mirrored (via SQLServer mirroring, no replication) to a third server. Note that 99% of the data is replicated outgoing, so the server should rarely need to update its data. As the (merge and transactional) replication tasks are not time-critical, I would like to reduce their priority or somehow slow them down, so they don't affect the database performance that much. How would you implement that?

• can I force server to always use turboboost?

  - by javapowered

  I'm using HP DL360p Gen8 with 2 * Xeon E5-2640. I do not load CPU 100%, i load it only ~10% and so I guess turboboost is not activated. However I'm using my server for trading so I absolutely don't care about CPU loading but I always want to process my data asap. So I want server to operate using maximum 3 GHz. I.e. 90% of CPU time I don't have anything to process. 10% of CPU time I have data to process. But I need to process it ASAP. I need every single microsecond. So I want server to operate always at maximum "turboboosted" mode. Is it possible?

• 8-bit game creator software

  - by dag729

  Hi, Anyone knows about some 8-bit game creator software that runs under GNU/Linux? I want to make some funny game in my spare time, but I prefer to have a tool (or a set of tools) that will help to keep it just a spare-time-project, thus not involving programming! :D Thanks in advance EDIT: For instance, some month ago I tried FPS Creator, being a frontend of DarkGame Studio. Well, FPS Creator is for a 3D FPS game: what I meant is a software similar to this one, but concening 8-bit'ish game.

• How to require a cell input if another cell has a value

  - by Connor

  I'm trying to edit the VBA for one of my workbooks so that If there is a value in column A, then a value for column C is required or else the file won't save, but i'm having some trouble with this. I can get excel to check a cell for any input and require it have input, but I need it to check if a different cell has an input before requiring input. This is because not all of the lines in my spreadsheet will be used all of the time, but some people forget to put very important pieces of information in the spreadsheet which throws some of our balances off. An SKU is entered on the sheet when we switch to a new one, and I want the program to make sure there is an amount of product in a given cell every time a new SKU is entered onto the sheet. Thanks.

• ruby on rails gitorious setup on ubuntu

  - by dogmatic69

  Ive been trying to install gitorious for a while now which required ruby and rails etc. Ive finally got rails pages serving but cant finish the installation of gitorious because the gem version is too new. the error logs say please run 'rake ultrasphinx:configure' and that gives rake ultrasphinx:configure (in /var/www/apps/gitorious) rake aborted! uninitialized constant ActiveSupport::Dependencies::Mutex /var/www/apps/gitorious/Rakefile:10:in `require' (See full trace by running task with --trace) From searching google this is beacuse of the wrong gem verison. Cant find a way to down grade it. apparently sudo gem update --system 1.4.2 should do the trick but ubuntu 10.10 does not like this. ERROR: While executing gem ... (RuntimeError) gem update --system is disabled on Debian, because it will overwrite the content of the rubygems Debian package, and might break your Debian system in subtle ways. The Debian-supported way to update rubygems is through apt-get, using Debian official repositories. If you really know what you are doing, you can still update rubygems by setting the REALLY_GEM_UPDATE_SYSTEM environment variable, but please remember that this is completely unsupported by Debian. So i added export REALLY_GEM_UPDATE_SYSTEM=1 to .bashrc and reloaded it with . ~/.bashrc and still the same. ive tried various forms of setting this environmental variable with no luck. Ive also been told on #gitorious irc channel to add the file config/initializers/rubygems.rb with the line require "thread" to it. This has done nothing. EDIT: Just found another way which was rvm install rubygems 1.4.2 and it gave: Removing old Rubygems files... Installing rubygems dedicated to ruby-1.8.7-p334...

• How to estimate a server specifications for this particular system? [on hold]

  - by Alvaro Fallas

  I'm working in a college project and I'm supposed to specify the server's hardware to hold a system. The system is some kind of social network. And it is supposed to hold around 100 000 users the first year, also the system must be able to handle 1000 users working at the same time. It is the first time I'm asked to do something like this, so I hope you can give me a hand and help me because I feel a little lost. The system's data base is Mysql. I found some server configurations offered by Amazon Web Services, but I don't know which of them is the better for my system due to lack of experience Hope you can help me.

• Mac keeps switching to second graphics card

  - by 1.21 gigawatts

  I have a MacBook Pro and whenever I enter certain apps (video camera app or Photoshop for example, the graphics card switched. I didn't know this was going on at first; just that the screen kept changing colors as I opened or closed different software. Later someone told me that the software was causing the OSX to switch graphics cards. It's annoying. How do I keep one graphics card (the better one) enabled all the time? I don't care about power consumption because it is plugged in all the time (though I'm curious how much difference it makes). I just want one graphics card enabled.

• Server 2008, 2 NICs, 2 fixed IPs - big delays using internet

  - by user46055

  Hi geniuses I have an all in one Windows 2008 server, configured with AD/DHCP/DNS/RRAS - all set up with wizards and no specific tweaking. The server has 2 network adapters : one of which ("MyWAN") is plugged into our office's internet connection, the other ("MyLAN") is plugged into a local switch, which is also where all our desktops are connected. So this one server is doing everything. When first set up, MyLAN had a fixed IP of 192.168.2.1 and served the desktops with DHCP scope 192.168.2.50-99. It also told them to use 192.168.2.1 as DNS and gateway. MyWAN was setup to take its IP etc from DHCP, being handled by the building's router and ADSL modem etc. All desktops were setup to use DHCP. This all worked perfectly fine, until I recently changed MyWAN to have a static IP (I wanted to access it from home, and needed to give it a static IP to port map in the building's router). Things still work, but there is now a long delay when accessing the internet. The actual speed is as before when downloading, but there is a pause of 3-6 secs when connecting to new hosts (for example if I browse to slashdot from either a desktop or the server itself, it'll hang on connecting to slashdot.org, hang again on connecting to *.fsdn, *.google-analytics.com and all the other hosts referenced from the main page). If I ping slashdot.org from the server, I get the following : Pinging slashdot.org [216.34.181.45] with 32 bytes of data: Reply from 192.168.2.1: Destination host unreachable. Reply from 216.34.181.45: bytes=32 time=99ms TTL=239 Reply from 216.34.181.45: bytes=32 time=100ms TTL=239 Reply from 216.34.181.45: bytes=32 time=101ms TTL=239 Pinging anywhere external always seems to hit 192.168.2.1 first, which doesn't seem right. Trying tracert from the server gives the following : Tracing route to slashdot.org [216.34.181.45] over a maximum of 30 hops: 1 MYSERVER01.intranet [192.168.2.1] reports: Destination host unreachable Trying tracert from a desktop gives the following : Tracing route to slashdot.org [216.34.181.45] over a maximum of 30 hops: 1 <1 ms * <1 ms MYSERVER [192.168.2.1] 2 * * * Request timed out. 3 6 ms 6 ms 6 ms dsl-gw1.ge.mer.uk.webtapestry.net [217.151.111.17] 4 38 ms 239 ms 251 ms gw-router.ge.mer.uk.webtapestry.net [217.151.111.13] ...and then all is fine after that. I think that DNS is working fine because the domain names are getting translated to correct IPs immediately. DHCP seems to be okay? So perhaps it's something up with my RRAS setup - although I can't see any option during the setup wizard which I would have filled in differently. I've also tried changing the binding order of the two network connections, to prioritise MyWAN, but that doesn't seem to have done anything. Any idea what's up? Many thanks - Rob

• DLINK WBR-1310B Wireless Router seems to hang...

  - by Ira Baxter

  I have a brand new DLINK-1310B Wireless Router (box never before opened, although I bought it at the neighborhood computer junk store). I am using it at home (and in fact am using it at this instant from a wireless laptop). When operative, I can ping it at 192.168.0.1, and I can log into it from the PC attached to it by LAN and from the wireless PC at //192.168.0.1. In the course of the day since I've installed, it seems to have locked up 3 times. Each time the symptoms are my web browser (or other IP service, e.g., POP3) stops with a "No internet connection" error. Attempts to contact the router via 192.168.0.1 get no reaction, from either the wireless laptop or from the hardwired PC sitting next to it. It doesn't respond to pings to that address either. Power cycling the router fixes it. I've seen discussion in other questions about aging cheap electronics. Its too new to be aged. Anybody else seen this behavior with a DLINK-1310? Or do I just need to exchange it for another and try again? (I hate rolling dice, I bought the DLINK because a previous Linksys died of apparant heating problems, how many do I have to cycle through before I get something that works and is long-term stable?). Remarkably, nobody talks about how much software is in a router. Is the stuff just buggy? EDIT: Happened again, while I was working on the wireless Vista laptop. (Seems like once an hour?) I was a little more careful this time. The wireless laptop can ping it. It can't get the login screen. I visited the LAN-connected PC (takes me a minute to walk from the laptop to the PC at the other end of the house), and attempted to visit a random web page. Surprise, that worked! And, now, after a minute walking back to the laptop, I can reconnect the wireless laptop, and get to the login page from it. Strange the time/date has been reset back to 2002. (I'll swear I set it and saved the system configuration after updating the firmware; it made me redo every other bit of reconfiguration again). Is there something funny about wireless leases expiring? The router says the leases it is handing out are good for 180 minutes, and the delay-to-inaccessible was only about an hour. The DSL connection seems to have a 10 minute lease.

• How to generate a 8 bit per sample wav audio file in VLC

  - by Ahmed safan

  I'm using the following vlc command line to extract first 5 minutes of audio from video file "-I dummy -vvv --no-sout-video --sout-audio --no-sout-rtp-sap --no-sout-standard-sap --ttl=1 --sout-transcode-threads=5 --sout-transcode-high-priority --sout-keep --sout #transcode{acodec=s16l,channels=1,samplerate=8000,ab=64}:std{mux=wav,access=file,dst="c:\dest.wav"} "c:\originalvideo.mpg" --start-time=0 --stop-time=300 vlc://quit"; if ab=64 =64 k bits per second and samples per second=8 k samples then bits per sample=64/8=8 bits per sample but the problem is that the output file always has samples of 16 bits per sample. I know that sample can contain bits from 8 , 16, 24 to 32 bits per sample. i want to get 8 bits per sample file how can this be done ?

• How to quickly switch monitors on multi-monitor setup?

  - by Saxtus

  At my desktop PC, I have 3 displays hooked up on my Palit GeForce GTX 480 to extend my desktop: DVI: Samsung SyncMaster T220 (22" 16:10, 1680x1050, as my main) DVI: Samsung SyncMaster 940BF (19" 4:3, 1280x1024) HDMI: Sony Bravia KDL-32D3000 (32" 16:9, 1360x768) As expected, the GFX card can only utilize 2 of the displays at any given time, so I have to manually switch using Windows' "Display Properties" dialog, each time I want to switch between them. I've tried UltraMon, DisplayFusion and PowerStrip (so please don't refer me to a question where those are given as solutions) but they are unable to switch monitors. Instead they can only change display resolutions and settings on the existing active monitors, with specially weird results when I've saved the monitor states and then tried to switch monitors using the saved states! Any idea on how to bypass the awful "Display Properties" dialog and it's "confirm your change" timer?

• Tail the filename, not the file

  - by Craig Walker

  In UNIX (OS X BSD to be precise), I have a "tail -f" command on a log file. From time to time I want to delete this log file so I can more easily review it in my text editor. I delete the file, and then my program recreates it after new activity. However, my tail command (and anything else that was watching the old log file) doesn't update; it's still watching the old, deleted log file. I think I understand why this is (file names simply being pointers to blocks of file data). I'd like to know how I can work around this. Ideally, my tail command (and anything else I point to the file) would be able to read the data from the new file when the file name has been deleted and recreated. How would I do this?

• Prevent Ultrabay HDD from ejecting on sleep

  - by Bryce Evans

  I have a lenovo T430s thinkpad with a small SSD primary drive and 500gb ultrabay drive. When I put the computer to sleep and then return, I get the message titled "problem ejecting < drive name " "Windows can't stop your 'Generic volume' device because a program is still using it." This pop up is very annoying every time every time I use the computer. I don't want to disable write caching [D:Hardware[drive]policiesquick removal] because I want best performance and never remove the drive. Any ways to avoid this pop up?

• Disable PXE progamatically in parallels?

  I'm running Parallels 4.0 on Mac OS X 10.5.8. I'm trying to create a bunch of Virtual Machines from the commandline, using the prlctl tool, like so: $ prlctl create test1 -o linux -d centos $ prlctl set test1 --device-del cdrom0 $ prlctl start test1 Now, each time I start a new VM, the VM spends time waiting for a PXE boot. I'd like to turn this off. Can I disable PXE requests using Parallels or a Parallels commandline tool? Or, can I set the boot order of a VM from the commandline?

• Change the format of the date column in Thunderbird

  - by TheOmega

  I want to change the format of the "Date"-column in the messagelist in Thunderbird. For mails from today, I want to display only the time, not the date. For mails from before today, I want to display only the date, not the time. This is the same setup mutt uses. I know of the Date display format wiki article, which describes how to change the date format, but you can only switch between five predefined formats, and none of them is "Date only". I also know of the ConfigDate extension, but it's got the same limitations, you can't define a new date format.

• Suggestions for Troubleshooting WIndows 7 lockups

  - by Craig L

  I've got a Dell Latitude E6500 that was working fine under Vista x64. I got one of the new Seagate 500GB Hybrid SSD/HD 2.5 drives and thought.. hmm.. let's try Win 7 x64 on it. Bottom line: It works great for hours and then it will hard lock. I don't mean BSOD (or whatever the Win7 equivalent is). I mean my screen is displaying a static image (if there is a clock displayed, it will be frozen at the time the lockup occurred) and the mouse and keyboard do not work. Control-Alt-Delete will not work. I have to hold down the power button to reboot. The event log records NOTHING at the time the lockup occurs. Obviously something is happening to the system to cause the lockup, but the default Windows 7 x64 doesn't log it. How can I log the things Windows doesn't normally log in Event Viewer ?

• FTP Synchronization software for Mac or PC

  - by evanmcd

  Hi, I've been using FTP Synchronizer for awhile and generally have had pretty good results with it. But, I've just moved to a Mac full-time (at work as well as home now) so want to get a native client if I can. I've tried the only one that I've found - SuperFlexibleSynchronizer - but it crashed every time I loaded up an FTP to FTP synch attempt. The most important features to me are: 1) ability to synch with a large number of files (thousands), as I generally work on sites with large number of files. 2) FTP to FTP synch. This would be very helpful as I work with some CMS based sites for which users upload files while on staging and don't want to move files locally first before moving live. Thanks! Evan

• Where are Credentials stored for Network Drives on WinXP?

  - by Tom Tresansky

  I have a drive mapped to a folder on a remote machine that I connect to using the Cisco VPN client. The password to the Windows account I use on that remote machine has changed. I had stored the username/password locally, using Window's remember my password feature, so I wouldn't have to enter it every time (the enter user/password login dialog used to appear each time I attempted to open the remote folder, and I would have to look up and enter my credentials). The password to that remote Windows account has changed. Now, I am no longer prompted to enter a user name / password, but instead, upon trying to open the remote folder, receive a message: unknown user name or bad password. How do I view and change these stored credentials?

• How to choose my own filename format for subscribed podcast files?

  - by meomaxy

  I subscribe to several podcasts where the filenames of the downloaded mp3 files have no particular pattern to them. When I copy the directory of accumulated mp3 files into my mp3 player, the files play in alphabetical order. What I really want is to play the files chronologically by release date. I currently use iTunes on Windows XP to download the files. What I do now is manually rename the files, adding the date in YYYYMMDD format to the start of each filename so that an alphabetical listing of files will correspond to their chronological order when I listen to them later in PocketTunes on my Palm Centro. Is there some way to get the release date into the filename automatically? If so, I could automate or possibly skip the file renaming step. I would switch from iTunes to something else if that would solve my problem. The file creation time on my local disk isn't a reliable indicator because sometimes I download a few days worth of content at one time, and the files don't necessarily get downloaded in chronological order.

• How do you check Driver Verifier logs on Windows 7 after catching a faulty driver?

  - by Wolf

  I kept getting BSODs on a clean install of Windows 7 (plus updates), so I decided to run Driver Verifier. I had to select all drivers, since it didn't catch the culprit when I didn't include Microsoft drivers. I know it is not a hardware problem since everything is working fine on Linux and memtest86+ is not reporting any errors in the RAM (8 GB). This time, it caught the faulty driver and gave me a BSOD telling me so. Using WhoCrashed, I could verify what was the last error message with the parameters and the source. Yet, the source is always the kernel (ntoskrnl.exe) and the bugcheck this time was 0xC4 (0x85, 0xFFFFF9804429AFC0, 0x2, 0x11B948). After searching on the web, I found out "the driver called MmMapLockedPages without having locked down the MDL pages." As I am not developing any driver, this is of no use to me. However, I would like to know which driver caused Driver Verifier to trigger an alert, so I can either disable it, or rollback to a previous version in order not to get crashes anymore.

• Change sysout logging level for Weblogic

  - by Justin Voss

  When I run a local copy of Weblogic, I like to see the output in the console so that I can observe my app's logging messages. But, Weblogic spits out a lot of log messages I don't care about, like these: [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' 08-29-2010 01:02:21 INFO Getting a JNDI connection [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' 08-29-2010 01:02:21 INFO Connection Returned.
