• Temporary boot problem after thunder storm - likely causes?

  - by alastairs

  The village where I live was sat under a thunder cloud for most of Friday, and we suffered a few power fluctuations (specifically, what seemed to be split-second outages). When I got back home from work, I found that my PCs had shut down during one of these outages. When I went to boot one of them back up, I couldn't get anything to display on screen, nor did the boot seem to complete correctly. I tried a number of things - unplugging different bits of hardware, swapping graphics adaptors, etc. - to no avail. I thought I was looking at a fried motherboard or CPU. Power seemed to be distributed correctly to the peripherals (the drives all appeared to be working) so I figured it couldn't be the PSU. Eventually I unplugged it from the mains and left it overnight (approx 12hrs unplugged). I tried it again this morning, and it booted up correctly. Woo-hoo! I have all my equipment protected by surge-protected power strips, so I don't think a spike caused these problems. Obviously it has something to do with the power fluctuations, and maybe the PSU in the problem machine got itself confused somehow. The questions are, for future reference and to help people with similar problems: What are the likely causes of the boot failure I experienced? Is a UPS a simple and cost-effective solution, or might other things help prevent this happening in future? What UPS can you recommend (my budget is limited)?

• Stop Picasa (Mac) from scanning my harddrive

  - by Bodyscanner

  I want to use Picasa desktop app instead of the tedious & clunky web interface to share a couple of photos. Every time I launch Picasa it proceeds to open an annoying pop-up/tool-tip which flicks through every file on my HD using <=95% of CPU. I don't want this so I click the X. It appears again. I try to drag it somewhere less annoying onscreen but it pings back. I look in prefs for an option to turn it off. I give up and quit app until a new build comes out, which I download and repeat the above. WTF?! I understand Google can't be as cool as Apple - iPhoto isn't perfect by any means but at least it looks nice and 'just works'. I want to launch Picasa, not have it go through everything, not have 1000's of random pics and HD cruft on display in the list, and then perhaps drag in a few photos and upload them. Any idea of if that is possible? </rant>

• update from debian lenny to squeeze

  - by Daniel

  I'm trying to update from debian lenny to squeeze on my 64bit root server and did the following so far: modifying sources.list apt-get update apt-get upgrade apt-get install linux-image-2.6-amd64 The last step leads to the following error-output: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

• 32 core (each physical core) 2.2 GhZ or 12 core (6 physical cores) 3.0GHZ?

  - by Tejaswi Rana

  I am working on a multithreaded application (Forex trading app built on C#) and had the client upgrade from the 12 core 3.0GHZ machine (Intel) to a 32 core 2.2 Ghz machine (AMD). The PassMark benchmark results were significantly higher when using multicores doing Integer, Floating and other calculations while for a single core calculation it was a bit slower than the pack (others that were being compared to with similar config as the 12 core one). Oh it also comes with 64 GB RAM (4 times as the other one) and a much faster SSD. So after configuring and running the application on that machine, not only did it not perform as well, it was significantly slower. We're talking about 30seconds - 1 minute slower on an app that usually completes processing within 5-20 secs. The application uses MAX DEGREE of PARALLELISM (TPL) which I've tried setting to number of cores and also half of that. I've also tried running single threaded and without setting any limits in parallel threading. While it may be the hardware has some issues, I am wondering if the CPU processing speed is the issue. I can overclock to 3.0 GHZ. But is that even a good idea? Server Info - AMD http://www.passmark.com/forum/showthread.php?4013-AMD-Dual-6272-performance-is-60-lower-than-benchmarks Seems that benchmark was wrong to start with - officially. Intel i7 3930k OS (same in both) Windows 7 Professional 64-bit

• How can I regain control over a "stuck" scroll bar?

  - by jonsca

  I normally have a lot of tabs open in the browser at one time, which normally doesn't cause any problems. Occasionally, though, the page will have fully rendered, the scroll bar is at the top of its track on the right, but placing the the mouse pointer on the scroll bar does not allow me to get control of it (and using the arrow at the bottom of the scroll bar doesn't work either). This seems to happen to me in both Firefox and Chrome, both latest versions. There is normally no load on the CPU, and while my memory usage can be high (especially with Chrome), I still usually have 25% left. I fear that this is one of those "for your own good" features, to prevent scrolling down a page that may still have elements loading and/or a stuck script, but I'm wondering whether or not there is a setting in Firefox or Chrome (or perhaps Windows in general) that will allow the scroll bar to be "released" even though the browser may be busy? It may be "2002" of me, but I wouldn't mind being able to scroll along gradually, even if the page hasn't had time to fully render all of the images, etc., yet. Does such an advanced setting exist "under the hood"?

• Streaming to PS3 with NAS and built-in dlna server?

  - by philt

  With consumer-grade hardware, is it possible to successfully stream 1080p mp4 videos to a PS3? I have a linksys router that can only do 10/100. The PS3 is wired to it with cat5e cable, and the PS3 itself supports gigabit ethernet. I would upgrade the router and get one that supports gigabit ethernet if it could handle streaming like this. It currently does work with minor jerkiness streaming from my mac to the PS3, but fast-forward/reverse and "goto" (equivalent of scene selection) take forever and/or fail completely. And streaming from my mac of course requires the mac to be on at all times. When I put the movies on an external USB drive and connect to the PS3 directly, it performs flawlessly. Fast forward and everything works great. So I was thinking about getting a NAS, but I don't know if any inexpensive NAS (i.e. Buffalo Linkstation Live, WD My Book World Edition, D-Link DNS-321, etc.) can actually deliver the performance necessary to do this, even with gigabit ethernet?

• A fatal exception 0E occured at 0028:xxxxxx in VxD IOS(01)

  - by winlin

  I get a blue screen of death in my windows 98 machine every time I boot it. I can't reach to my desktop.

• IIS 7.5 error 500 in fastcgi module after upgrading wordpress to 3.0.2

  - by Maniac13

  I am running multiple wordpress blogs on the following setup: Server 2008 R2; IIS 7.5; PHP 5.3.3; MySQL 5.0.7; I upgraded my wordpress install from 2.9.2 to 3.0.2 (on 2 different sites) today and the upgrade went fine.

• Need help diagnosing my machine

  - by Tom Collins

  I have something that just slows my computer to a crawl sometimes. Not running anything big. Yesterday all I had running (besides background apps) were Firefox & Windows Explorer and could barely even switch screens. Nothing showing up in the task manager as hogging CPUs. I have all non-essential services stopped (MySQl & MSSQL) unless I need them. I made some restore points not long ago, but they disappeared. This is a development mach with a LOT of apps installed, so I really, really do not want to re-install Windows. So, what I'm looking for are ideas or tools I can use to help diagnose this problem. The only clues I have is this started right after I installed Office 2013 (with Office 2010 still installed as well) installed Visual Studio 2012 (also keeping 2010 as a co-install) and installed MSSQL 2012 (upgrade from 2008, no co-install) Also, computer runs fine in Safe Mode. I've just ran out of ideas of what to check. Any help / suggestions would much appreciated. Thanks P.S. I'm running Win 7 Pro (x64). Office is also 64 bit. Visual Studio & MSSQL are 64 bit if that option was available (not sure).

• Dedicated server with a lot of storage and good support - and cost-effective

  - by Martin Burger

  Hello, I am from Germany and looking for a dedicated server located in the US with a lot of storage: 750 - 1500 GB. CPU speed and amount of memory are secondary, the server will host large amounts of media files via http and ftp - the basic task is to help people exchange media files. In Germany, there are some good offers, like "Root Server EQ6" at www.hetzner.de. For example, that company provides support of high quality, and their plans are very cost-effective. The plan mentioned above costs about $90 per month and provides two 1500 GB SATA-II HDDs (Software-RAID 1). In the US, I found (amongst others) Go Daddy and rackspace. Go Daddy offers some "Storage Monster" plans that include 2 x 1,000 GB hard drives for about $180 per month - already twice as much as Hetzner above. However, I found some blog and forum entries that complain about the support provided by Go Daddy. Rackspace seems to provide decent support, but they are very "upscale". Their dedicated servers are customizable and start at $419 - thus, about 4.5 times as much as Hetzner. Can anybody recommend a solution / plan that is comparable to the one by Hetzner? Or are prices for dedicated servers in general much higher than in Germany? Regards, Martin

• SBS 2003 stops to respond often due to limited memory

  - by Sanoj

  I have a Windows SBS 2003 Std that regularly stops to respond (crashes), in about every 20th day. The only thing I can see in the logs (the one that are mailed to the administrator) 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. When the server stops to respond, the screen saver cannot be deactivated, no DNS-look-ups is working so the client's can't access Internet. And applications on the server do not reply. And we have to press the power-button to restart the server. For the moment it has an uptime of 19 days and have 2 345MB in memory use (idle) and sqlservr is using 819 MB. So I guess it will crash soon. Is there any solution to this problem? Could I limit sqlservr to some memory?

• TV-out worked, now doesn't. May the problem be the cable, TV, driver, OS, graphic card?

  - by Petruza

  I have a CRT TV hooked to the PC, which once worked great, now doesn't. I can't consider getting a newer TV, this one is used in an MAME arcade cabinet so it has to be a CRT for best old school look and feel. It's connected through the TV-out connector of my graphic card. When it worked, I had Windows XP, the same PC and the same card. Now I have windows 7, not sure if the OS switch caused the malfunction as I don't use the TV-out all the time. Can it be an upgrade of the Nvidia driver? I thought it may be the S-video to RCA cable, but tried 3 different cables and neither worked. In fact, one of them, that unlike the other two, has a single RCA output connector instead of two, behaves differently, although it doesn't work, but it does the following: When I open the NVidia settings panel, or when I change a setting and click Apply then the TV flashes for a split second and you can see the windows screen, but then it goes back to blank. So any clues what can be failing here, and some advice? Possible failures, please comment on the one you suspect the most: NVidia driver version Windows version Cable Graphic card's TV out other?

• Ways to go about optimizing website performance WordPress, Amazon EC2 Apache and RDS MySQL

  - by fuzzybee

  I have 6 WordPress websites running on 1 single EC2 instance. All the the websites are connecting to databases in 1 same RDS instance. Earlier today, traffic to the largest website peaked and the RDS instance went bottle-neck - CPU utilization was 100% for over an hour. It affected all of my websites as it took them all forever to load. In order to prevent such issue from happening again, which of the following will matter most so that I invest time and effort in first of all? (I will work on all later, I just need to prioritise now) To improve caching for all websites To fine-tune the database server To fine-tune my Apache server What will be the effect on user experience for my websites? Some quick searches show that I should limit number of concurrent connections to my web server but wouldn't that prevent users from accessing my websites? More background: My largest website has 140k visits and 660k page views a month. The other 5 websites should add up much less than that. I'm using a large EC2 instance as the web server I'm using a medium RDS instance as the database server What I've already done: Use W3 Total Cache plugin for caching for most the websites, especially the largest one (I can barely anything else in terms of caching I could do for the largest website) Am I using my resources wastefully or is there simply not enough resources for my websites - or rather, how do I answer that question myself?

• Windows Bluescreen - atikmpag.sys

  - by Mochan

  Information Name: atikmpag.sys bluescreen (BSOD or BlueScreen of Death) Error code: 0x00000116 Appears when: Playing games, watching videos Can be reproduced: Yes Cause: Graphics Card is the main assumption System Specifications Before we begin - I will inform you of my specifications. OS: Windows 7 x64 Home Edition Model: Dell Inspiron 15R Special Edition (aka Inspiron 7520) (Add 2GB of RAM to the model linked) Hard Drive: 1TB CPU: Intel Quad-Core i7 Sandy Bridge (I think) Processor at 2.10GHz (I think it can be clocked to 3GHz?) RAM: 6GB (I think 1 x 4GB and 1 x 2GB) Display: 15.6" HD (1366x768) Graphics: AMD Radeon HD 7500M 2GB Details So now that you know some basics about my computer, I'll get to the problem. Being an Ubuntu user I hardly use Windows, but occasionally I do. Like to run Skyrim and other games incompatible with Linux and WINE. The new Sims 3 Seasons patch is also now not supported. When playing these two games and other ones, theoretically. I have also heard others saying that while watching HD movies and video series it also happens. While watching the bluescreen as it happens, I see it is the 'atikmpag.sys' error. I have not installed much and nothing significant. I think I have downloaded Skyrim, Firefox and The Sims 3. I haven't done much more... since Ubuntu is definitely the best in comparison! (No hate, just a joke :P). I can reproduce it easily (just by running a game for less than a minute). It is always there each time, but it's never at a specific time or anything. So far I have found that it may be caused by lack of power to the graphics card, or it may be damaged or fried. Since I've had the computer for a mere 4 months (and have had other problems with it also). I have contacted Dell but they are useless beyond belief. Anyone with any information, solutions or details are encouraged to share your knowledge, as it would be immensely appreciated.

• How do I know what hardware to buy to meet my needs?

  - by Darth Android

  While Stack Exchange does not permit shopping recommendations, it doesn't provide any general advice to consider when buying hardware. So, instead of just telling those that ask what to buy that it's not allowed, let's tell them how to figure out what they need. When looking forward to build a computer, how do I know what to buy? How do I find out if a given CPU will be enough for a certain game or application that I want to run? How do I find out if a given graphics card will be enough for a certain game or application? What is important when looking at motherboards? How much memory do I need? How do I know how much wattage I need for a power supply? What size case do I need? What relevant standards do I need to read up on and be aware of? PCI, PCIe, SATA, USB 2.0, USB 3.0, etc... What "gotchas" do I need to be on the lookout for? Please keep responses generation-agnostic to ensure they will be helpful to our future users. :)

• How can I tell GoogleBot that a subdirectory is now a subdomain? [migrated]

  - by cwd

  I had about a million pages of a catalog indexed under a subdirectory, and now that's moved to a subdomain. GoogleBot is crawling each one of them and getting a 301 redirect to the new location. Even though I have set up the redirect rule in the apache sites-enabled configuration file, (i.e. it's early on when apache does the redirect - PHP is not even getting loaded), even though I have done that, the server isn't handling the load well. GoogleBot is making around 5 requests per second, and on top of my normal traffic that is hiking up the CPU for a few hours at a time. I checked in Webmaster Tools and the corresponding documentation for a way to let Google know that the content had been moved from a subdirectory to a subdomain, but with little luck. Basically the most helpful thing I saw said to just send 301 headers for the new location. How can I tell GoogleBot that a subdirectory is now a subdomain? If that is not an option, how can I more efficiently send 301 redirects out for a particular subdomain? I was thinking perhaps the Nginx server but I'm not sure that I can run both Apache and Nginx side by side on port 80 for different subdomains.

• Why can't I install Java?

  - by Patrick

  I've been searching high and low for someone who can help me. I've been trying for a month. A month. to install Java on my new PC to no avail. No tech support forum can seem to help me. It all started while playing tekkit one day. I kept running out of memory (using the 32-bit JRE 7 u45) so I decided to install the 64-bit version. I uninstalled the 32-bit version first, for some reason, and downloaded the 64 bit runtime. In the installer, I go through all the normal screens until the installation progress bar appears. Then, it just sits there. No progress is made. No CPU is used by the installer, or any of its dependencies. The installer will stay like this for hours, days, and in one case a whole week without doing anything at all. I've tried installing older versions, the 32-bit version, even Java 6 and none of them will install. UAC is disabled, I've run regedit, CCleaner, and any other "fix-it" program there is. It's getting to the point where I may just have to wipe my hard drives and start over. I have several applications that require java, so this is an absolute necessity. Please, please, someone have the answer. Here are my system specs: -Intel i7-3770k -AsRock z77 Extreme3 -Samsung 840 pro SSD -WD Caviar Black 1tb

• SQL Server Installation: Is it 32 or 64 bit?

  - by CapBBeard

  Recently I was performing an OS upgrade on one of our DB servers, moving from Server 2003 to Server 2008. The DBMS is SQL Server 2005. While reinstalling SQL on the new Windows installation, I went to another of our DB servers to verify a couple of settings. Now, I always thought this second server was Server 2003 x64 + SQL 2005 x64 (from what I'd been told), but I now have my doubts about this. I now suspect that it is in fact only 32 bit SQL, however I'd like to verify this. Here's some details: The OS is definitely 64 bit. xp_msver shows Platform as NT INTEL X86 SELECT @@VERSION shows Microsoft SQL Server 2005 - 9.00.4035.00 (Intel X86)... However sqlservr.exe is not shown with '* 32' in taskmgr, does anyone know why this is the case, if it is in fact 32 bit as claimed? Despite this, it does seem to be running out of the x86 program files folder. If I do the same checks on a confirmed 64 bit installation, it does give back the expected 64 bit readings, which can only prove that this server in question is only running in 32 bit. Now, that being the case, the question arises about how much memory this '32 bit' install can use. Task manager reports about 3.5GB memory usage for sqlservr.exe (The server has 16GB physical). I suspect that AWE has not been configured at all, and therefore the server will be significantly under-utilised (remembering that the OS is 64 bit) if SQL is simply using a 32bit address space. Is this assumption correct? I feel the server should have SQL reinstalled as 64 bit in order to fully utilise the hardware platform, however it is currently heavily in production; this will be no easy task. I suspect we may just have to configure AWE correctly and let it be for the time being (Unless this is a bad idea?). I apologise that this question is a little vague/lost; I'm no SQL expert, just trying to get a handle on what's going on here.

• Slow performance on VMWare Linux server after Tomcat install

  - by Loftx

  We have a VMWare ESXi 4.1 server hosting a number of Linux and Windows guests. Recently a new Linux guest was added to this server and seemed to be performing well. Tomcat and some other applications on this server were then installed which seem to have caused the server to run really slowly without any obvious resource issues. Slow performance include: The time taken to bring up the password prompt over ssh takes a few seconds when it was previously instantaneous. The time taken to unzip a zip file which was previously a few seconds now takes around 30 seconds The time taken to compile vmware tools has increased by similar factors Both the VMWare console and monitoring commands don't report any issues with high CPU or memory usage but something is obviously slowing the server down somehow. Does anyone have any ideas what may be causing this issue and how it can be resolved? Thanks, Tom Edit As per your questions I’ve looked at some of the performance indicators on both the VM host and VM guest indicated. Firstly I tried reserving the full amount of memory (3gb) for this VM – no other machines on this server have any memory reservation. The swap in rate and swap out rate for the VM host and guest are now both zero. Balloon memory on the guest is zero and on the host is 3.5gb (total memory on the host is 12gb) The swap rate for the guest is also zero. Swap used by the host is 200mb on average. Compression and decompression rates for the host and guest are zero. Command aborts for the host are zero. Read latency is very low – maximum 10ms average 0.8ms. Write latency is higher – a few spikes to 170ms but mostly around 25ms – is this bad? Queue command latency is zero . Physical disk read latency averages 5ms but often 10ms Physical disk write latency averages 15ms but is often 20ms I hope this helps - let me know if you need any more information.

• Upgrading openSUSE 11.1 with Plesk Panel 9.3 to PHP 5.3

  - by Jonathan Hogervorst

  Hello, I'm running a VPS with openSUSE 11.1 (i586). On the VPS is Parallels Plesk Panel 9.3.0 installed. The current PHP-version is PHP 5.2.11. I want to upgrade PHP to PHP 5.3, but I can't find good instructions on how to do this. If I check for updates in Zypper, it says this is the latest release. In the Plesk Updates isn't an update either, both via the webbased interface and the command line interface. On Software.openSUSE.org I can find packages for PHP 5.3.1 in both the server:php/server_apache_openSUSE_11.1-repo and the server:php/openSUSE_11.1-repo (can't post the link because I'm a newbie here). But if I add one of those to Zypper, I still don't see an update. Is there here somebody who knows how to do this? And is it completely safe to update that way? I don't want to end up with a broken VPS... Thanks! Jonathan

• Backup data rate on Raspberry Pi maxing out at 5 Mb/s. Why?

  - by bastibe

  I set up my Raspberry Pi as a Time Machine, as documented here. At the moment, the Raspberry Pi is connected to my MacBook Pro using a direct Ethernet cable. Also, an external hard drive (laptop drive) is connected to the Raspberry Pi using the USB port. However, backups are pretty slow. Activity Monitor claims that the Network is transferring a very steady 5 Mb/s, where my Time Capsule is transferring up to 8 Mb/s with a lot of fluctuation. The Raspberry Pi self-reports (top) that its CPU is only half-used, with about equal parts afpd, usb-storage and jbd2/sda1-8. Thus, I think that the processing power of the Raspberry Pi does not seem to be the problem here. To me, this looks like there is some kind of bottleneck that maxes out at 5 Mb/s thus potentially having my backups run at less than their potential speed. To the best of my knowledge, this might be the afp-daemon, the usb-bus or the external hard drive. So, my question is, how could I identify the true culprit and what can I do about it?

• What folders to encrypt with EFS on Windows 7 laptop?

  - by Joe Schmoe

  Since I've been using my laptop more as a laptop recently (carrying it around) I am now evaluating my strategy to protect confidential information in case it is stolen. Keep in mind that my laptop is 6 years old (Lenovo T61 with 8 GB or RAM, 2GHz dual core CPU). It runs Windows 7 fine but it is no speedy demon. It doesn't support AES instruction set. I've been using TrueCrypt volume mounted on demand for really important stuff like financial statements forever. Nothing else is encrypted. I just finished my evaluation of EFS, Bitlocker and took a closer look at TrueCrypt again. I've come to conclusion that boot partition encryption via Bitlocker or TrueCrypt is not worth the hassle. I may decide in the future to use Bitlocker or TrueCrypt to encrypt one of the data volumes but at this point I intend to use EFS to encrypt parts of my hard drive that contain data that I wouldn't want exposed. The purpose of this post is to get your feedback about what folders should be encrypted from the general point of view (of course everyone will have something specific in addition) Here is what I thought of so far (will update if I think of something else): 1) AppData\Local\Microsoft\Outlook - Outlook files 2) AppData\Local\Thunderbird\Profiles and AppData\Roaming\Thunderbird\Profiles- Thunderbird profiles, not sure yet where exactly data is stored. 3) AppData\Roaming\Mozilla\Firefox\Profiles\djdsakdjh.default\bookmarkbackups - Firefox bookmark backup. Is there a separate location for "main" Firefox bookmark file? I haven't figured it out yet. 4) Bookmarks for Chrome (don't know where it's bookmarks are) and Internet Explorer ($Username\Favorites) - I don't really use them but why not to secure that as well. 5) Downloads\, My Documents\ and My Pictures\ folders I don't think I need to encrypt, say, latest service pack for Visual Studio. So I will probably create subfolder called "Secure" in all of these folders and set it to "Encrypted". Anything sensitive I will save in this folder. Any other suggestions? Again, this is from the point of view of your "regular office user".
