• ATI radeon hd 5450 Graphics Card Issues

  - by RGM-79FP GM Striker

  I have an Old Dell Optiplex 755 SFF with an Intel Core 2 Processor (windows 7). Now This can hold a PCI-E x16 port. Now I got an ATI Radeon HD 5450 low profile. I plugged and played and it fits without a hitch, the software installed too! , now for the graphics well... It doesn't really work at all as it seems to freeze at the moment that it loads on the windows logo. It loads into safe mode so I'm not really sure what the problem is. Any ideas, I read the dell forums and they should be somewhat compatible... with the specs so I'm at a loss here. and I am a novice here. Ideas? Edit I have tried to reset the cmos,no luck there. I have tried to move the ram as well. nothing big happened.

• How does NTFS compression affect performance?

  - by DragonLord

  I've heard that NTFS compression can reduce performance due to extra CPU usage, but I've read reports that it may actually increase performance because of reduced disk reads. How exactly does NTFS compression affect system performance? Notes: I'm running a laptop with a 5400 RPM hard drive, and many of the things I do on it are I/O bound. The processor is a AMD Phenom II with four cores running at 2.0 GHz. The system is defragmented regularly using UltraDefrag. The workload is mixed read-write, with reads occurring somewhat more often than writes. The files to be compressed include personal documents and selected programs, including several (less demanding) games and Visual Studio (which tends to be I/O bound more often than not).

• SBS 2003 crashes often due to limited memory

  - by Sanoj

  I have a Windows SBS 2003 Std that regularly crashes, in about every 20th day. The only thing I can see in the logs is that used memory increases with about 30MB/day. The process that uses more and more memory is sqlservr. We don't have much installed on the server; a Point-Of-Sale-system that uses Pervasive SQL as database and an Accounting application. We just have 2GB of RAM and I could upgrade to 4GB but I think that this just delay the problem. Is there any solution to this problem? Could I limit sqlservr to some memory?

• Mutli-processor workstation as a workstation/server

  - by posdef

  I work in a research institute and a number of programs we use are computationally intensive (I actually wrote one of them). Right now we have one computer that is dedicated for one of these programs (with local accounts only, as in users physically sitting in front of that pc) and the other programs are run on individual workstations assigned to people. I have been looking around to common brands such as Dell and HP, for a some sort of a small/medium scale server, which can be used as a workhorse by sending tasks remotely. It appears as if there is nothing in between workstations with one 6-core processor and a bunch of extras (like fancy graphics etc) and rack mount servers with ridiculous amount of RAM and HDD expansion capabilities but still relatively little number of processors/cores. I wonder if what I am looking for is such a small niche product? Are there other solutions that I might not be aware of? Does anyone know of a multi proc- multi-core workstation/server that is still within the reasonable

• Sar data not collected for 10 minutes

  - by Ichorus

  We have a RedHat server whose only job is to run a JBoss server. Monitors said that memory usage spiked (we have the JVM limited to far less than the total memory on the system) and JBoss crashed. We restarted and everything seems ok now. Odd thing is that sar data for 10 min leading up to the crash is simply not there. Load average got up to the 50s. I have seen severely busy systems (350+ Load Average) still collect sar data. Does anyone have any idea what could cause sar to stop collecting data?

• Good reasons to keep 32-bit Microsoft Windows desktop OSes

  - by Mark Henderson

  Server software has been 64-bit only for a while now (Since Server 2008 R2 for Windows, even earlier for Exchange and Sharepoint) and even Ubuntu are pushing you away from 32-bit versions for their server OSes. But is there any good, quantifiable reason to keep a 32-bit desktop operating system maintained? We're preparing our Windows 8 images for the (unfortunate?) few that will be early adopters. The majority of our desktop computers have 4gb or less of RAM, but I would love to not have to bother supporting a 32-bit flavoured operating system any more. Any reason why I should?

• Is it possible to interrupt or cancel the trash-delete process?

  - by pete

  I am connected to the company server, onsite not remote, which is Windows based. When, in the OS finder, I go to delete a file or directory that resides on the window-based server, the trash progress panel appears as usual. Not infrequently it will just hang there appearing to be active but no progress occurs on the progress bar. So the X is chosen to stop or cancel the process. A new panel appears, and while appearing to be active, again, just hangs there indefinitely. My lack of reputation prevents posting a screen shot - sorry. The question then is this: Is there a way via the Activity Monitor, Terminal, etc. to interrupt this deleting process in the Mac OS? Currently, I have to force shutdown and reboot to eradicate the ever-deleting panel. Finder relaunch does not solve and only eliminates the finder until I force reboot. Any assistance is appreciated. Thanks, Pete iMac, Mac OS X (10.6.8), i7-2.8ghz, 8gb ram

• Satellite TV on my PC?

  - by jasondavis

  What would be a good solution for hooking up the satellite TV box (Dish network) in my room to be able to watch it on my PC and possibly record video from it? Please share with me the best cards, cables, software, anything else needed to do this in the most efficient way? I am looking at the WinTV-HVR from Hauppauge. I am not sure, for performance, what would be the best to go with, PCI, PCI express, USB2.0? Also on the Hauppauge website I saw this note: "WinTV-PVR products will not work in PC systems with 4GB or more of memory." The new PC I am building will be 12-24gb of DDR3 RAM, does that mean their products will not work at all with my memory? So confused now!

• site timing out when under heavy load

  - by naunu

  My client sends out eblasts at 8am monday/wed/friday. Between 8:15-8:45 the site becomes extremely slow and many users sessions timeout. My setup: Mediatemple VE 2gb dedicated ram (3 burst) Ubuntu 9.10 Apache2-mpm-worker PHP5.3-fcgi MySQL 5 I recently tried to remedy the problem by switching from apache2-mpm-prefork to mpm-worker, but am still having the same issues. My apache settings are: Timeout 100 KeepAlive On MaxKeepAliveRequests 100 <IfModule mpm_worker_module> StartServers 12 MinSpareThreads 25 MaxSpareThreads 96 ThreadLimit 96 ThreadsPerChild 25 MaxClients 225 MaxRequestsPerChild 0 </IfModule> The site is only getting ~10,000 page views during the 8am-9am hour, which I dont think should be stressing the server too badly. Maybe it is an error with the PHP settings, or bandwidth per unit time, or the site outgrew the server? Any suggestions would be very helpful - as you can see i've given it a good go before looking for help (installed mpm-worker). Also, can anyone suggest to me some free load testing software, or a tutorial on mod_status? Thank you

• Apache service hung and incoming requests not accepted

  - by Gnanam

  Hi, My production server is running Apache v2.2.4 with mod_mono v1.2.4 on CentOS release 5.2 (Final). Suddenly, Apache service hung during normal usage time (approx. 1 pm EDT). Traffic is not too high at this time. This is the first time we're noticing this kind of behaviour in our server. I noticed from access log that even subsequent requests are also not received, even though there were incoming requests. I then manually tried to invoke my application call from web browser, it never returned successfully but it was still loading. I found no unusual behaviour/activity in: 1) Apache access_log and error_log 2) No kernel level errors found in /var/log/messages I've no other option but ended up restarting Apache service. Any idea on what would cause Apache to hang and thereby not allowing subsequent incoming requests? How do I debug/diagnose when this happens next time? Experts advice/recommendation on this are highly appreciated.

• Truecrypt or default Disk Utility on Mac?

  - by Kaushik Gopal

  Windows by default doesn't come with a password protect folder option (other that Win7 ultimate), so I used to swear by Truecrypt which was great. But I've read in a couple of places that Mac OS X by default has a way of protecting folders using the Default Disk Utility. So my question is which is better, using TrueCrypt on the Mac or just sticking with the default Disk Utils app? Can somebody let me know the advantages of one over the other? A summary from the very helpful answers below: if you're looking for cross-platform usage Truecrypt is the obvious tool of choice if you're looking for convenience, and intend to stick only to the Mac platform, use the default Disk Utils app.

• Why does QuickTime lag in Firefox if I don't put my mouse over it?

  - by Jim McKeeth

  This has happened for me as long as I can remember. Since the first version of Firefox, on multiple computers and under different versions of Windows. QuickTime plays fine in IE and Chrome (even with Firefox in the background), but in Firefox if my mouse is not over the QuickTime window then it will start to studder, then lag and eventually just stop. To be honest, I do keep quite a few tabs open, but Firefox stays at 1% CPU (even when QuickTime runs) and I have a few gigs of free RAM. It is the same for any resolution of video or audio. If the mouse is just one pixel in the client area of the QuickTime then it usually plays fine. Other video formats typically play fine. Does anyone else notice this behavior? Ultimately I would like a fix besides keeping my mouse over the QuickTime window.

• Is there any descent open-source search engine solutions?

  - by Nazariy

  Few weeks ago my friend asked me how hard is it to launch your own search engine service with list of websites that suppose to be crawled time to time. First what come at my mind was Google Custom Search however pricing policy is quite tricky and would drain your budget if you reach 500K queries per year. Another solution I found here was SearchBlox, which can be compared to Google Mini service. It's quite good solution if you planing to cover search over small amount of websites but for larger projects it is not very handy. I also found few other search platforms like Lucene, Hadoop and Xapian which seems to be quite powerful solutions to reach Google search quality, and Nutch as a web crawler. As most of open-source projects they share same problem, luck of comprehensive guidance of usage, examples and it's expected that you are expert in this subject. I'm wondering if any of you using this solutions, which of them would you recommend, and what should I be aware of?

• Squid Proxy Antivirus - Recommendations / Performance

  - by Jon Rhoades

  Due to our user's increasing expertise at downloading virus and the like, we are investigating adding Antivirus to our Squid proxy. A casual Google reveals several free and one paid: HAVP squid-vscan Viralator Safe Squid (commercial) None of the 'free' ones have reached v1 yet, nor do any inspire huge confidence form their websites (although of course I would rather they spent their time on the app rather than their website!). Does anybody have experience with any of these (or any other similar apps). If so are they suitable for a production network with 400ish concurrent users, and what sort of CPU/RAM requirements does it have?

• 1080p playback on external monitor

  - by xibalban

  My system (netbook) specs: 1.6 GHz dual core atom N2600 2 GB DDR3 RAM Integrated GMA3600 GPU Win 7 Professional 32 Bit Daum Pot Player V-1.5 The issue: I downloaded a 1.33 GB sized 1920 x 1080 HD documentary (file extension: mp4) and it plays without a hitch using pot player. However, when I connected an external display (an LED Full HD 24" monitor) using D-Sub, the video plays fine but the player controls become very unresponsive. For instance, it takes about 40 seconds to exit full screen while playing. I tried: Installed/updated all the latest monitor drivers Updated the VGA drivers for GMA3600 No other programs ran while the video played, with most unwanted services and background processes disabled/killed. CPU usage goes only up to 49% when the video plays Question: What may I do in order to improve the player response/video playback experience? Do I need to play with (or change) Pot Player's default video decoders, etc?

• Separating user resources - Windows Server 2008 (Terminal Server)

  - by Christopher Wilson

  At the moment I am running a Windows Terminal Server 2008 for around 10 clients that use the server to run programs and access data. Is there anyway to separate the resources of each user so that they do not impact each other in terms of resources. User 1: Opens program User 2: Notices slow down I have looked into using Windows System Resource Manager but do not know if it provides what I need and if there are any other 3rd party tools that also provide this functionality. Any answer is appreciated. Server Specs: HP ProLiant ML110 G7 Processor: Intel® Xeon® E3-1220 (4 core, 3.1 GHz, 8MB, 80W, 1333/t) RAM: 12GB DDR3 ECC 1TB HDD

• virtual machines: optimal host os to run Windows XP guest os?

  - by user61132

  My department doesn't have the budget to upgrade my ailing Dell D620 laptop. However, I do have the option to buy my own personal computer, then use my company-issued ISO image to run Windows XP as my guest os using virtualbox or vmware. Therefore, last month, I bought an Acer AX3910-U3012 desktop that had Windows 7 as the host os (and 8G RAM). In short, I was disappointed with the performance while trying to run WinXP as the guest os. (It didn't perform much better than my laptop.) Just wondering what the optimal host os would be for running Windows XP as the guest os? (No, I can't use my company-issued ISO image to build the os for my personal computer.) FWIW, I'm willing to spend up to $2k if it's REALLY worth it, but would prefer to spend no more than $1k. Also, in an effort to cut costs, I'd prefer buy a desktop instead of a laptop. Thanks for any/all feedback.

• Database OR Array

  - by rezoner

  What is the exact point of using external database system if I have simple relations (95% querries are dependant on ID). I am storing users and their stats. Why would I use external database if I can have neat constructions like: db.users[32] = something Array of 500K users is not that big effort for RAM Pros are: no problematic asynchronity (instant results) easy export/import dealing with database like with a native object LITERALLY ps. and considerations: Would it be faster or slower to do collection[3] than db.query("select ... I am going to store it as a file/s There is only ONE application/process accessing this data, and the code is executed line by line - please don't elaborate about locking. Please don't answer with database propositions but why to use external DB over native array/object - I have experience in a few databases - that's not the case. What I am building is a client/gateway/server(s) game. Gateway deals with all users data, processing, authenticating, writing statistics e.t.c No other part of software needs to access directly to this data/database.

• How to fix steam issues when playing games

  - by Vyren Media

  So I got call of duty black Ops on my PC (Windows 7, 64bit, 8gig ram, 3.0ghz processor) but when I want to start the game I get this error message. Steam must be running to play this game.

I have tried reinstalling over and over but no success at all. Is it like direct X you could just download and install or what...Any ideas will be GREATLY appreciated.

• vista winsxs folder eats disk space

  - by Simpzon

  My machine has been running Vista Ultimate 64-Bit for about two years now. ServicePacks SP1 and SP2 are installed, too. The system partition has a size of 55 GB, which should be quite comfortable under normal circumstances, but about 40GB (no typo) are used by the Windows-Folder, especially the subfolder winsxs, which takes about 35 GB. I have already uninstalled as many programs as possible and did run compcln.exe, to reduce it, but this only gained 2-3 GB. What can I do to clean up without risking system stability? I'm a software developer and this is my daily work environment, which means - I can't risk to get strange side-effects from blindly deleting stuff. - You can maybe deduce some typical usage patterns from this information. Any suggestions?

• Nexus One USB freezes Vista SP2 Quad Core

  - by user25479

  My Nexus One (N1) will occasionally freeze my Vista 32bit SP2 Quad Core 2.4GHz during POST. MB is ASUS P5N-E SLI with 4GB of RAM. The PC will be booting and when I connect the N1 via USB, the boot sequence will freeze, then continue once I unplug the N1 USB link. It happens whether the N1 is in USB debugging mode and when it is not. I'm not sure whether this is an N1 hw/fw issue, system interaction with my PC, or a result of my N1 development environment (I'm using the Eclipse Galileo IDE for Java Developers, primarily compiling to API Level 7. Eclipse has also occasionally frozen although I haven't established N1 USB cause-and-effect on that issue). Is anyone else experiencing these symptom?

• How to use HTML markup tags inside Bash script

  - by CONtext

  I have crontab and a simple bash script that sends me emails every often containing PHP, NGINX, MYSQL errors from their log files. This is a simplified example. #/home/user/status.sh [email protected] PHP_ERROR=`tail -5 /var/log/php-fpm/error.log` NGINX_ERROR=`tail -5 /var/log/nginx/error.log` MYSQL_ERROR=`tail /var/log/mysqld.log` DISK_SPACE=`df -h` echo " Today's, server report:: ================================== DISK_SPACE: $DISK_SPACE --------------------------------- MEMORY_USAGE: $MEMORY_USAGE ----------------------------------- NGINX ERROR: $NGINX_ERROR ----------------------------------- PHP ERRORS: $PHP_ERROR ------------------------------------ MYSQL_ERRORS: $MYSQL_ERROR ------------------------------------- " | mail -s "Server reports" $EMAIL I know this is a very basic usage, but as you can see, I am trying to separate the errors, but not of the html tags including \n are working. So, my question is, is it possible to use HTML tags to format the text, if not .. then what are the alternatives.

• Why did windows change the elevation requirements of my AutoHotKey script, and how can I prevent such in the future?

  - by monsto

  I was working on an AutoHotKey (AHK) script to create prefab mouse movements for a very simple model viewer. I worked on it for a good hour. I zipped the script, posted it to a forum, and thought "oh hey, I should add bla bla bla to the script". When I returned to the program, the AHK script would not work. I could see the mouse movements working in other programs (notepad, chrome, etc), but not where I had been working the previous hour. After several hours of throwing darts at the troubleshooting wall, I discovered that the fix was to set the AHK.exe to Run as Administrator. The question here are multiple Why did Windows 7, in all it's wisdom, suddenly decide that elevation was necessary in the middle of usage? Can these permission requirements somehow be reverted by, say, removing a key from the registry or something? How can this kind of Windows behaviour be avoided in the future?

• How have you saved green by going green?

  - by Bob

  For the purpose of this question, I am interested in server/datacenter related hardware. Have you had any measureable amount of ROI by swapping existing hardware to more "green" or energy efficient hardware? For example, VMWare says you can reduce energy consumption by up to 80% by using virtualization. I have also heard of a cooling solution from HP which is suppose to reduce a small amount of engery usage (<25% I think). Google has also done something by integrating a UPS into their power supplies to reduce energy consumption. Any real world experiences would be great, but if you have any details on initial cost, savings and pay off time about what changes were make that would fantastic. I am not only interested in virtualization, I am interested in anything.
