  • mysql is not using multiple cpus

    - by mhost
    Our MySQL server has been using a lot of CPU lately (it's reached 100% several times and stays there for a while) and I noticed that it the CPU load is all on one core of one cpu. I was hoping to spread that out to all 4 on my server. I have been tweaking the MySQL settings to use more ram and less cpu, but it still occasionally reaches very high CPU usage. It seems like everything about the topic refers to thread_concurrency (which I've read is a solaris only setting). What can I do in Linux? Thanks.

  • Crontab + .sh + php

    - by Kristaps Karlsons
    Hi. I'm trying to call a shell script every 5 minutes, witch executes php file under root. # crontab -l */5 * * * * /home/regularuser/call.sh permissions: -rw-rw-rw- 1 root root 162 Jun 6 23:40 call.php -rwxr-xr-x 1 root root 66 Jun 7 01:20 call.sh call.sh contents: #!/bin/bash php -q /home/regularuser/call.php echo "request processed" My problem is that my php file doesn't get executed via crontab. However, if I call call.sh - everything works perfectly. I'm new to crontab and shell scripting, so any advice/resources are welcome.

  • How do I get a listing of music files on a specific drive

    - by Kevin34
    I'm helping someone setup thier IPOD, but they are using Windows 7, and I know XP. I don't see the music in the directory lising on his computer that I see on the IPOD. So I'm trying to search for all music files on e: In Windows XP, this is easy. Windows 7 has changed everything. I googled this, and I found to type "music" in the Windows search bar. This result in music "Libraries." Great. There's still not a listing of the files. I can search for *.wma, but that doesn't list all the music on the IPOD. There are many types of music files, how do I get a list of ALL music files on JUST drive e:? Again, on XP this was VERY easy.

  • New power supply, now computer doesn't recognise hard drive?

    - by Mike
    Ok, I bought a new power supply, because my old one was too damn loud. I hooked it up to my PC, turned it on, everything is looking fine, start up detects my DVD drive, 2 hard disks.. then I get the message "BOOT FAILURE INSERT SYSTEM DISK". Now I've seen some other people talk about going into BIOS and changing the start up to the HDD and not the CD.. well I've done that and it doesn't help. If I let windows load up and it asks me to which partition I wish to install windows, no partition is present. It's as if after the initial start up the drives arn't being found. I plugged my old (but loud) PSU back in, connected up all the cables, and it works perfectly. Why does the new PSU not detect my HDD's after the first BIOS screen start up? Any ideas? :)

  • 12.04 LTS Apache2 writing files from webpage at runtime has no effect - possible read/write permissions?

    - by J Green
    I'm running 12.04LTS with Apache and Mono in VirtualBox, with the goal of hosting a web app (coded in ASP.NET and C#) on my local network. The scripts on the page are able to successfully read from text files in the same directory as my site (/var/www/mysite/) but do not seem to be able to write. I'm sure the code works, because it did with my testing in Visual Web Developer on Windows. I don't get any errors, but when I click the button on the loaded webpage, the text file in question does not change. I'm fairly new to Linux in general, so I'm not too familiar with how to set permissions properly, and it may be a permissions issue. Unfortunately, I have searched all over the internet and haven't found a solution that worked, but I've tried (perhaps incorrectly) changing the owner of the files in question to www-root, changing the mode to a+rw, but sadly to no avail. I have tried everything here but it doesn't work: Whats the simplest way to edit and add files to "/var/www"? I hope someone can help me out.

  • Chromium never stops loading iGoogle

    - by regulatethis
    I almost always keep a tab open on google.com/ig. Recently I've noticed that the "loading" animation for that tab never stops spinning, even though the page appears to be fully loaded. Even though there's no direct problem with this, I find the animation really distracting and to be honest it's driving me crazy. I've done a few things to try to figure this out. I've removed every single one of my gadgets (so my igoogle is blank), but that made no difference. I've disabled adblock and scriptno. nothing. I've watched the network console in developer tools to look for resources that haven't finished loading, but it looks like everything is done. I'm all out of ideas. For my sanity's sake, please help.

  • OOP Structure for web application

    - by Query
    Ok so I have a website in which users complete tasks to earn points. When they earn enough points, they rise in rank. The site from my understanding is very basic and only executes one query or two queries at most a page. There is a user table, a support ticket table, and an orders table. All of these contain a relational row for username. Our class was familiarized with OOP back in highschool with Java but that was for video games and I could grasp the concept on why you would need a class player and class enemy. However I don't understand it's web application. At least not in my situation. I understand the user class might contain stuff like: getUsername getPoints getEmail setEmail addPoints (does this belong here? OR only things the user can manipulate should be here?) etc.. But I'm at a loss with everything else such as user registration. Can you help give me a wire framework that I could wrap my head around? Pointing me to a good eBook would help greatly

  • How do I fully clear Firefox's cache of CSS and JS files?

    - by Mike Webb
    I work on a website at my work. The issue is that if I visit the site, which uses the cached versions of the CSS and JS files, and then upload an updated copy of a CSS/JS file, Firefox will still use the cached version. I can go to 'Tools-Clear Recent History' and clear the Cache of "Everything" and it still uses the cached version of the files. It will eventually updated and use the new files, but it can takes hours for this change to occur. So, how do I completely clear Firefox's cache of these files?

  • Why do I need to add my application pool identity to the IIS_IUSRS group?

    - by smcolligan
    I'm setting up a .NET v4.0 web application on a Windows 2008 R2/IIS 7.5 server that uses a domain account for the application pool identity. When I access the site, I get the following error: The current identity () does not have write access to 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files' According to this: http://learn.iis.net/page.aspx/140/understanding-built-in-user-and-group-accounts-in-iis/ the identity of the worker process is added to the IIS_IUSRS group when the process starts. This seems to work fine for the existing .NET v2.0 applications I have running on the same server (I have not had to add their domain account application pool identities to IIS_IUSRS group). This does not seem to be the case for the first .NET v4.0 web application I'm setting up. Once I add the identity to the group, everything works fine. I suspect something is not configured correctly that is forcing me to do this. I would like to understand this before rolling out more sites/servers. Thanks in advance for your help...

  • UPS compatible with Linux box?

    - by Somebody still uses you MS-DOS
    I'm buying this unit from deal extreme: it's a bitorrent downloader, with NAS capability. I'm interested in sharing an external HD in it, with media and backup purposes. I'm afraid of energy problems (don't know if this is the correct term), corrupting my mounted drives (like after a storm), so I thought about buying an UPS that sends a "signal" to my Linux box, and a script in my Linux box would unmout everything to avoid problems. Do this "UPS signal" feature exists? Do you have model suggestions? Thanks!

  • ASUS N550 laptop not charging on ubuntu after updating kernel

    - by OBY Trance
    I'm using Ubuntu 13.10 on a pretty new ASUS N550jv laptop. When I was using kernel linux-image-3.11.0-11 everything was quite well (kinda..), however, when I updated the kernel using the automatic update, the kernels which were released afterwards (12+) were faulty on my machine, and caused the battery not to be charged and only stay at their current charging level (even when the machine was off!) The only fix I had was to roll-back to the '..11' version (on boot screen - advanced options), and hard-reboot (AC cord disconnected and reconnected) but now version 14 was released and "pushed away" the good old version 11. How can I fix that?? Please help me...

  • Oracle 11g network configuration

    - by Kylo
    Hi, I installed Oracle 11g Enterprise Edition on my Windows 7 Pro. My problem is that I cannot log into database from other host (local network). When I connect to database using Oracle SQLdeveloper everything is ok as long as I specify 'localhost' in connection configuration. However, when I change it to '192.168.0.190' which is my host IP address I get 'The Network Adapter could not establish the connection'. I get the same error when logging in from other host in local network. What is the problem?

  • Mac and different Spaces: conserving the windows arragement when changing the external monitor

    - by user10826
    Hi, I use Mac OS X Leopard with 4 different Spaces and an external monitor at workplace, which is located above the laptop. On each Space I work on a different project, with different terminal windows and Xcode and Finder windows. The problem happens when I am at home, then I use an external monitor but now located at left position. When the MacBook wakes up, everything gets messed up and even some windows switch from one space to another. Could I somehow fix it so always the windows belonging to one Space remain there and also the association to main/external monitor even if I change to another external monitor? Thanks

  • What is the preferred pattern when attaching a 'runtime object'?

    - by sebf
    In my application I have the following: public class NeatObject { /* lots of static data, and configuration flags */ } public class NeatObjectConsumer { void DoCleverStuffWithObjectOnGPU(NeatObject obj); } Where NeatObject and its consumer are used to control the GPU. The idea being that, the configuration of an instance of NeatObject and its members, define how the consumer instance behaves. The object can be passed around, edited, and most importantly serialised/deserialised by the application, with and without knowledge of NeatObjectConsumer, then provided back to the consumer to do something else. The purpose of this seperation is: The consumer manages hardware resources, which change depending on the computer, and even on the execution of the application, making preserving the state of an object which does everything difficult. Avoids circular references if the assembly that contains the consumer needs to reference one that only needs to know about NeatObject. However, there is a complication in that the consumer creates hardware resources and needs to associate them with NeatObject. These don't need to be preserved, but still need to be retrieved. DoCleverStuffWithObjectOnGPU() will be called many, many times during execution and so any bottleneck is a concern, therefore I would like to avoid dictionary lookups. What is the preferred method of attaching this information to NeatObject? By preferred, I mean intuitive - other coders can see immediately what is going on - and robust - method doesn't invite playing with the resources or present them in such a way as to make them easily corruptible. Essentially, I want to add my own metadata - how should I do it? Try to use 'actual metadata' functionality like Reflection? A member of the type of an abstract class? Unmanaged pointers? If you took on a project that used this pattern, what would you have liked the previous developer to do?

  • mysql server, open 'dead' connections

    - by Jeff
    my basic question is what kind of impact does this have on the server.. lets say for example, there is an older program in my company that opens connections to a mysql database server at a high rate (everything they do with the application basically opens a server connections) however, this application was not designed in the way to dispose of the connections after they where created.. alot of the time the connections remain open but are never used again, open 'dead' connections i guess you could say. they just remain connected until the server times them out, or until an admin goes in and removes the sleeping connections manually. im guessing this could be responsible for sometimes not able to connect errors etc. that we receive from other systems that try to access the mysql database? (connections limit reached) could this slow down the server as well? curious what all this could exactly cause. thanks!

  • Complex, yet simple crafting system model

    - by KatShot
    I'm working on some arcade shooter/slasher, and the main logline is "Kick'em with everything you want". There's not so many enemies in GDD, main focus is on tons of weapons and gadgets to cause mayhem. To get weapon, you need to craft it, and now crafting system looks simple, like: 1) You got three slots for weapon parts (like A, B, C) 2) You collect misc weapon parts, and when you got atleast one for every slot, you can craft a weapon (for example, if you got A1, B1, B2, B3 and C1, you can craft such models - A1B1C1, A1B2C1, A1B3C1) As for me, this crafting system is too simple, because weapon parts will just fall from the top of screen, often enough. That's why I'm thinking about adding some more crafting system levels, like resources (collect 10 scrap pieces to make part A1 or C3), etc. My question is: How can i add some more complex, still simple, transparent levels in crafting system? upd. For example, in Minecraft or Terraria, first 5-10 crafting recipies quite transparent and simple IMHO. But then it turns into huge mess to understand, how to craft this or that (for example, fishing rod)

  • Why is `cmd /C` living after it did its job?

    - by acidzombie24
    My question is why does "cmd" exist (idle) in my process after i update my exe? In my code i run this code to update myself and launch var args = string.Format(@"/C ping 1.1.1.1 -n 1 -w 3000 & move /Y ""{0}"" ""{1}"" & ""{1}"" {2}", updateFn, fn, exeargs); new Process() { StartInfo = new ProcessStartInfo(@"cmd", args) { CreateNoWindow = true, UseShellExecute = false } }.Start(); Environment.Exit(0); The idea is i exit right away and have ping stall for 3seconds before trying to replace my current exe with my updated exe. Then i launch with the necessary args The full arg for cmd looks like this /C ping 1.1.1.1 -n 1 -w 3000 & move /Y "c:\path\update" "c:\path\my.exe" & "c:\path\my.exe" exeargs Everything works fine however i see cmd in the taskmanager (looks to be idle) after my process is launched and correctly working. Why?

  • List all documents (webparts) and sites using a certain solution in sharepoint 2007

    - by tnolan
    I would like to uninstall a Sharepoint application template (GroupBoard Workspace to be exact) but I want to make sure nothing currently relies on it. I don't see any functions within stsadm that will tell me this information and I have even tried SPM which would work, but with such a huge site it's tedious to go through every single web and page to see which features are in use. Is there a way (probably with SQL using the id from stsadm -o enumsolutions) to list everything that relies on a template within a given solution, including webparts on custom pages? If this is not possible, what is the best way to check dependencies prior to uninstalling a solution (especially since GBW is not the only one on my axe list.) Note: I know that stsadm -o deletesolution will stop me from removing something that is in use, but I want to see all of the things that are using a given solution.

  • Why can't I access the WebUI of my DNS-323 NAS after a firmware upgrade?

    - by anonymous2
    Hi Everyone, I just bought a D-Link DNS-323 NAS Enclosure, and have run into a problem. I read that the firmware that had shipped with (1.07) did not support 2TB drives, so I downloaded firmware 1.08. Turned on the device for thwe first time and went straight to the WebUI (everything looked/worked fine) Proceeded with the firmware update, completed successfully. Rebooted and I cannot access the WebUI. I can see the NAS connected via my router interface I can also ping the ip adress assigned, but I cannot access the WebUI or find it via D-Link easy search software. I have tried the factory reset button, but that does not seem to be doing anything, the square blue light just keeps flashing from the moment the unit is powered on, whether I press the reset button or not, and the symptoms remain the same... PS. I did/do not have any drives installed yet. Please help?

  • Is GPU active when there are not any monitors?

    - by Mixer
    Does GPU render anything when there is no monitor plugged in? Today I turned my old PC into some kind of a "server" which means that I want it running 24/7. I don't need any display (I will operate through ssh) so when everything was set up I removed my monitor. After a hour I checked my graphic card's cooling system and it was still hot. My graphic card is GeForce 8600 (with DVI connector), OS is Debian Linux. What is the best solution in this situation (standalone server) if GPU is active and I don't want it to waste power?

  • CSS file not served by IIS 7.5 after multiple clear cache refreshes in a row in browser

    - by KenB
    We are experiencing an interesting issue with IIS 7.5 static caching and a css file. When we use IE to hit the page in question everything works fine - 200 OK on css file. When we refresh the page it works fine - 304 Not Modified on css file. When I refresh again with control key it reloads fine - 200 OK on css file. Now if I do a control key + refresh multiple times in a row really fast the css fails to load and in the developer tools network it says "Loading..." for the css file and it hangs never coming back. Any ideas?

  • How can I reset windows 7 file permissions?

    - by ssb
    I looked at this post and it seemed to be close to what I want, but my case might be a little worse: How can I reset my windows 7 file permissions to a rational state? Basically a while back I (very stupidly) changed the permissions on all sorts of system folders, and eventually rendered my computer virtually unusable. I managed to hack administrator privileges back onto key folders and getting it working, but in doing so I only modified permissions a lot more away from the natural state. I'm looking at this icacls stuff, but ultimately I need to reset EVERYTHING back to what it was in The Beginning, before I messed with it, from the C: directory all the way down. Right now application data is what's giving me problems, and I can't get it to work no matter how much I fiddle with those specific permissions. I will be forever grateful for help on how to do this without having to reformat.

  • Software for Company internal Website [closed]

    - by LordT
    hope this is the right stackexchange site to ask this: We've a group of webpages/services at work (SE Startup), ranging from SVN, trac, continous integration to link collections to a DMS. Nearly everything has an RSS Feed to get the info I need, with the exception of SVN. I'm looking for some kind of software that can integrate these well on a kind of start-page. The most recent changes, upcoming events etc should be clearly visible, as well as an option to search (the search will be provided from a different tool). A news area should be included as well. Currently, I'm pondering doing this with either wordpress or TWiki, although wordpress seems to be the simpler solution in terms of getting something good looking quickly. Authentication should be handled by HTTP-Basic Auth, which we already have in place and working well. I normally would consider Sharepoint a viable option for this, but we're exclusively mac and linux, I won't put up a windows server just for this.

  • Is it preferable to use POP or IMAP to check multiple google mail accounts from one?

    - by Adam Tuttle
    I have email accounts on several domains that use Google Mail, and thus far I've only ever used POP to send and receive mail from a single inbox. This is quite functional, and as long as I remember to select the appropriate FROM address when starting a new thread, mostly works without any additional thought: messages received on account A are replied to via account A, and so on. My only complaint is the lag -- I've seen sometimes as much as a half hour between messages arriving in an inbox before being imported into my primary inbox via POP. My question is this: Google also supports IMAP. Would that be in any way preferable over POP access? Reduced lag would be nice, but not at a general speed cost, if everything I do has to check another mailbox too.
