• How to setup Joomla CMS as a backend for iPhone app

  - by srik

  I would like my iPhone app to get dynamic content off the net. This content should be managed using a CMS. I have gone ahead and installed Joomla on my server and will be using the Joomla web interface to create and manage content. I would now like the iPhone app to login to my server and fetch the content. I do not want the complete web pages for my iPhone app. Instead, I want the content in the form of XML or JSON or some serialized format so that I can use the data in a custom layout native to the app. So I am looking for 2 things in particular: 1. How to setup HTTP based authentication for my iPhone app to access data from my server. 2. How to access the content in a serialized format (XML, JSON etc) Are there plugins/extensions/components I can use to achieve the same. Any advice on how this can be achieved would be helpful. I am completely new to setting up/using CMS.

• central apache log analysis of many hosts

  - by Jason Antman

  We have 30+ apache httpd servers, and are looking to perform analysis on the logs both for historical trending and near "real time" monitoring/alerting. I'm mainly interested in things like error rates (4xx/5xx), response time, overall request rate, etc. but it would also be very useful to pull out more compute-intensive statistics like unique client IPs and user agents per unit of time. I'm leaning towards building this as a centralized collector/server/storage, and am also considering the possibility of storing non-apache logs (i.e. general syslog, firewall logs, etc.) in the same system. Obviously a large part of this will probably have to be custom (at least the connection between pieces and the parsing/analysis we do), but I haven't been able to find much information on people who have done stuff like this, at least at shops smaller than Google/Facebook/etc. who can throw their log data into a hundred-node compute cluster and run Map/Reduce on it. The main things I'm looking for are: - All open source - Some way of collecting logs from apache machines that isn't too resource-intensive, and transports them relatively quickly over the network - Some way of storing them (NoSQL? key-value store?) on the backend, for a given amount of time (and then rolling them up into historical averages) - In the middle of this, a way of graphing in near-real-time (probably also with some statistical analysis on it) and hopefully alerting off of those graphs. Any suggestions/pointers/ideas, to either "products"/projects or descriptions of how other people do this would be greatly helpful. Unfortunately, we're not exactly a new-age-y devops shop, lots of old stuff, homogeneous infrastructure, and strained boxes.

• Why are my Windows 7 updates continuously failing?

  - by Chris C.

  I'm an advanced level user here with an odd issue. I have two Windows Updates that are failing to install, every single time. I'm getting a mysterious "Code 1" error on both updates, an error for which I'm having difficulty finding a solution. The updates in question are: Security Update for Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package (KB2538243) System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [May 2011] Because these updates are failing, the Shut Down button in my start menu always has the shield icon next to it, indicating that "new" updates will be installed on shut down. But, of course, they'll fail and when the PC is restarted, the shield icon is still there. When checking the update history and viewing the details of the failed updates, I get the following: Security Update for Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package (KB2538243) Installation date: ?6/?29/?2011 3:00 AM Installation status: Failed Error details: Code 1 Update type: Important A security issue has been identified leading to MFC application vulnerability in DLL planting due to MFC not specifying the full path to system/localization DLLs.

• Why does Windows/Microsoft Updates always take such a long time to detect available updates?

  - by RLH

  It's a common task for many of us who work in any form of IT position using Windows. Eventually you have to install/re-install a version of Windows and what follows is a very long OS updating process. For a long time I have accepted the fact that this is a slow process and that's all there is to it. There is a lot to download, and some updates require restarts followed by further updates... Ugh! This morning I had to go through the process of installing Windows XP with SP3. I'm installing the OS on a VM on an SSD and I've been working on this thing for over 6 hours. Although, think there are many ways to knit-pick this process for improvements, there is one step that is always particularly slow and I can not figure out a good reason why. That step is the detection step on a manual update. Specifically, when navigate to the Windows (or Microsoft) Updates page, and then click the 'Custom' button to detect your updates. It appears that your PC just sits there for a painful amount of time. Check your Task Manager and it looks like your PC is, in fact, locked because your CPU isn't cooking but that's certainly not the case. Somethings happening but I have no clue what's going on? What is the updating software doing? If the registry was being searched, shouldn't my CPU usage peak? Does anybody know what's happening? I can loosely justify why some of the steps in the update process take so long. However, this one doesn't seem to have any reasoning.

• Windows service fails to start with local user until password is entered again in logon tab

  - by Nick

  Basically we have a service where we use a local account as its logon. it has all the proper permissions, and everything is working fine, service starts and runs and all is good. Then one day, after rebooting, the service fails to start. Logs show incorrect password. Our technicians resolve the issue by simply retyping the password into the "Log On" tab from the services.msc. Unfortunately we have not been able to root cause. I suspect that the password that is stored for the service is lost somehow. Does anyone know where the password hash might be stored so we can check it? The only activities that seem to be possibly related are patching with Microsoft security patches, but we have multiple servers running the same service, and we have never seen more than one at a time, and its usually a different one each time when this occurrs. I believe this to be the same issue as this: Windows service fails to start with custom user until started once with local user But i was unable to add comments, and its really old.

• explanation of RAM specs, and what do I need for a Gaming rig

  - by ewok

  I am looking into upgrading my custom built PC's RAM. I use the machine mostly for gaming, but I don't really know a ton about RAM, so I wanted to ask a few questions. The research I've done tells me there is a negligible increase in speed for anything above 1600 MHz. is this true or is it worth the extra money to go higher? Other than drawing more power from the PSU, is there any real difference in performance with different voltages (1.5V vs 1.65V)? most of the kits I've found in the 2x4 1600 range have a CAS latency of 9 and timing of 9-9-9-24. For a significant increase in price (usually about 1.5x), I can get either 8 or 7 and lower timing. Is it worth the cost? What I am looking for here is someone to give a good explanation of what the different specs represent, and how that relates to the performance of the machine. Specifically, I'm looking for what specs I need to focus on for a good gaming rig. I am NOT looking for a "buy this, it's the best RAM" without an explanation of why. The information will be much more valuable as it will allow me to make my own informed decision. As they say, give a man a fish, he'll eat for a day. teach a man to fish, and he'll eat for the rest of his life.

• EC2 AMI won't boot after edit

  - by Eric Lars0n

  I did something stupid, I got a new laptop and copied everything over to the new one, then wiped the old one clean. Then I realized that I forgot to copy the private key out of .ssh that I use to connect to my AWS EBS backed instance. So I can't log in to my custom AMI. So I created a new Volume from the Snapshot of the AMI, then started up a public instance and attached the Volume to it, edit the sshd_config to allow for password log in. Unmounted the volume, detached it, made a snapshot of it, then made a new AMI from the snapshot. The new AMI launches, but never passes the Status Checks and is not reachable. What am I doing wrong? Or alternatively how can I fix my problem?

• OpenVZ: Choosing right MySQL-Server depending on host

  - by Scheintod

  What I have: Two servers running Wheezy/OpenVZ with One MySQL container on each host master/master replicated (mysql1/mysql2) Replicated DNS on each host (dns1/dns2) different web-containers on each host but regulary backuped to the other. What I want: Each container should use the "local" MySQL-Server (the one which runs on the same hardware-node). I'd like to be able to move the web-containers between the to hosts. Each container should choose the MySQL-Server (semi) automatically. This scheme should continue working if one host is down. What I tried: Currently I'm keeping track on which container should run on which host by DNS entries which are queries by scripts e.g. for questions like: "Which container should be backuped on/to which host." For choosing the right MySQL server I have one extra entry like "mysql.container_abc" which resolves to either mysql1/mysql2. So in the applications in the container I can use "mysql.container_abc" for e.g. mysql_connect and if I want to move the container around I just need to change the dns. Now I notices one problem with this approach: Every mysql_connect generates one DNS query because the dns is not cached and this slows the request down unnecessarily. What I would like better: Some way of passing the information on which host we are running to the container and using it directly instead of using DNS. E.g. some way of setting a custom /etc/hosts entry in the container. Or any other great idea. Doesn't have to include DNS but shouldn't require to much special "magic" inside the container.

• Stepmania + KDE4 = sound problem

  - by picca

  I cannot manage to get KDE4 + stepmania working.

Which is pretty bad for an application like this one. I'm quite sure that the problem is in phonon that is blocking the audio device to which StepMania needs to access directly. I think that I can fix this if I run other (lighter) window-manager than KDE4. But that is not a solution occasional linux user. Do I have any chance to get StepMania under KDE4 completely working?

• NFS-shared file-system is locking up

  - by fredden

  Our NFS-shared file-system is locking up. Please feel free to ask any questions you feel relevant. :) At the time, there are a lot of processes in "disk sleep" state, and the load averages on our machines sky-rocket. The machines are responsive on SSH, but our the majority of our websites (apache+mod_php) just hang, as does our email system (exim+dovecot). Any websites which don't require write access to the file-system continue to operate. The load averages continue to rise until some kind of time-out is reached, but for at least 10-15 minutes. I've seen load averages over 800, yet the machines are still responsive for actions which don't require writing to the shared file-system. I've been investigating a variety of options, which have all turned out to be red-herrings: nagios, proftpd, bind, cron tasks. I'm seeing these messages in the file server's system log: Jul 30 09:37:17 fs0 kernel: [1810036.560046] statd: server localhost not responding, timed out Jul 30 09:37:17 fs0 kernel: [1810036.560053] nsm_mon_unmon: rpc failed, status=-5 Jul 30 09:37:17 fs0 kernel: [1810036.560064] lockd: cannot monitor node2 Jul 30 09:38:22 fs0 kernel: [1810101.384027] statd: server localhost not responding, timed out Jul 30 09:38:22 fs0 kernel: [1810101.384033] nsm_mon_unmon: rpc failed, status=-5 Jul 30 09:38:22 fs0 kernel: [1810101.384044] lockd: cannot monitor node0 Software involved: VMWare, Debian lenny (64bit), ancient Red Hat (32 bit) (version 7 I believe), Debian etch (32bit) NFS, apache2+mod_php, exim, dovecot, bind, amanda, proftpd, nagios, cacti, drbd, heartbeat, keepalived, LVS, cron, ssmtp, NIS, svn, puppet, memcache, mysql, postgres Joomla!, Magento, Typo3, Midgard, Symfony, custom php apps

• Windows 8 Install Hanging at first white-font boot splash

  - by Omega

  I'm trying to install the Windows 8 preview on my Samsung Series 9 (2012, Ivy Bridge). I've done a bit of a custom scheme with this one: I'm using EFI/UEFI on this system. I've seen no indication that this system supports secure boot (yay!) My SSD is set up with GPT Ubuntu is already installed and working great via UEFI. I'm trying to boot the Windows 8 install from a USB stick via UEFI I don't have access to a CD drive. The problem is that the boot seems to hang at the very first splash screen that looks like this. White windows font, the little beads don't show up. My USB stick has an activity light and it does blink for the first few seconds, but then goes back to it's "nobody is talking to me" idle pulse. What I know: UEFI booting is definitely working. Windows 8 for those few seconds seems to have some kind of access to the USB drive. My Series 9 is running the latest BIOS/firmware. Any idea what I might be able to do to get Windows 8 installed??

• download and process a file by ftp at set intervals, with error handling, rescheduling and status messages

  - by compound eye

  I want to download a data file from a remote ftp server to my machine at regular intervals. Once the file is downloaded I want to call another script which will process the file. My development machine is mac os x, the eventual deployment environment is linux. What's would be the stock standard way to automate this? I know I can use cron to schedule curl to download and to run a script that will process the downloaded file at regular intervals, and I know could write a slightly more complex script or an application that would do this and add error handling, rescheduling and sending status emails. But one of my requirements for this project is to write as little custom code as possible, instead I should try to use standard, tried and true existing tools, and if I do have to write code, to try and write the most straightforward code possible. The reason for this is the code will potentially be installed on a large number of machines, all of which will need to be tweaked, customised and maintained by different people, long after I am gone from the project, so the intention is to use well documented, well supported tools as much as possible. This seems such a common task, there must be tools and scripts all over the internet, written by people who have carefully considered everything that could possibly go wrong when you need to download and process a file from a remote server at regular intervals, with error handling, rescheduling and sending status messages. Is that what Expect is for? What would you recommend? (the system will be downloading weather prediction data every six hours, so that the system can prepare in the event of bad weather warnings)

• Need advice in setting up server. fastCGI, suExec, speed, security, etc.

  - by lewisqic

  I am running my own dedicated server with centOS 5 and WHM/cPanel. I would like to configure my server to meet my needs but I need a little help. It will only be my own websites being run on this server. I'm still a little green when it comes to server administration so please forgive my ignorance. What I Would Like to Have: I need some public directories to be writable (for user image uploads and things like that) but I don't want those directories to have 777 permissions. I need individual accounts to have the ability to set custom php settings for their own account without affecting other accounts, whether through a php.ini file or through .htaccess or any other method. I would like things to run as fast as possible, whether that means using a php optimizer or cacher, such as eaccelerator or xcache or anything else. I need things to be as secure as possible. Here Are My Questions What should I use for my php handler? DSO? CGI? fastCGI? suPHP? Other? Should I be using suEXEC? What are the benefits or downfalls of this? What php optimizer/cacher is best to use? Are there any other security tips I need to know about all of this? I'd appreciate any advice or direction that can be offered. Thanks!

• (updated) Subfolder needs whitelist and standard redirect for all others

  - by Superstrong

  How can I allow access to the foo.html files in the .com/song/private/ subfolder for: a logged-in Wordpress user; or any referral domains (including subfolders) I add; or any URL on our own domain from the com/song/private folder; For all others, the user should be redirected to the corresponding public version of the Post, which is the same html filename and structured .com/song/foo.html. (The private versions uses a different template with different custom fields for each Post.) Update: Here's what I have so far: <Limit GET POST> order deny,allow deny from all allow from domain.com/song/private allow from otherdomain.com </Limit> RewriteRule ^(.*)$ ../$ [NC,L] More: Will that last rewrite rule take people back to the public version, from com/song/private/foo.html to com/song/foo.html? I found the following rule for detecting Wordpress logged-in status, but what do I put aferward with a RewriteRule, and will it work anyway? (If not, is there an alternative?) RewriteCond %{HTTP_COOKIE} !^.*wordpress_logged_in_.*$ N.B. I have added code to my root .htaccess allowing me to insert additional .htaccess files in other subfolders as needed. Copied from Stack Overflow, where they suggested I ask here.

• How can I use an own asp page as 404 error page on a Windows 7 pro IIS 7.5 local installation

  - by Edelcom

  Running Windows 7 Pro Running local IIS 7.5 ( for web development purposes ) Edited hosts file to be able to use http://www.sitestepper.dev Site build in subfolder of the inetpub/wwwroot/staplijst Site can be viewed using http://www.sitestepper.dev/staplijst/whatever-page.htm I have an http://www.sitestepper.dev/p.asp page I would like to call when an unknown page is requested. This technique works fine on the deployed version of this web site ( deployed on an Windows 2003 server running IIS 7 - not sure about the 7 but it is the version deployed with Windows 2003 server ). I tried ( in the Edit Custom Error Dialog ) : Execute a URL on this site: with value /staplijst/p.asp and Respond with a 302 redirect: with value http://www.sitestepper.dev/staplijst/p.asp I tried this in the properties of the 'Default Web Site' , and I tried this at the staplijst level. Even tried it with values without the /staplijst. I restarted the default web site after each change. And even stopped/started the Web service. But nothing seems to work, I keep getting the 'Server Error In Application "DEFAULT WEB SITE"' , HTTP Error 404.0 error. What am I missing here - probably something obvious, but I don't see it ? Thanks in advance

• What are good systems for managing PHP/MySQL infrastructure?

  - by sbrattla

  I work in a company which is about to migrate most applications from in-house custom built Java/Tomcat applications to Drupal. Due to company policies, applications and websites need to run on in-house servers. This means that we need infrastructure for Drupal (PHP/MySQL) applications. This must have been solved a million times already. I believe this is what web-hosting companies does every day. Even though we work on a much smaller scale than web-hosting companies, i assume it would make sense to look at the task as if we're going to have an internal small-scale web-hosting company. This means that the guys in IT operations could be "responsible" for "offering" web-hosting, while developers could use these "services". We have three environments; dev(elopment), test and prod(uction). It would make sense that developers could log in to a system and create/edit/delete dev and test sites as they'd like. Production sites should be available through the same system, but only available to IT ops. We need to work with clusters of web servers, meaning that an administration system should be capable of creating/editing/deleting sites across multiple servers. I know there's no "this is it" answer to my question; but what would be a good place to start to get going with this? Apart from the actual hardware, what would be a good administration system for this?

• Ways to parse NCSA combined based log files

  - by Kyle

  I've done a bit of site: searching with Google on Server Fault, Super User and Stack Overflow. I also checked non site specific results and and didn't really see a question like this, so here goes... I did spot this question, related to grep and awk which has some great knowledge but I don't feel the text qualification challenge was addressed. This question also broadens the scope to any platform and any program. I've got squid or apache logs based on the NCSA combined format. When I say based, meaning the first n col's in the file are per NCSA combined standards, there might be more col's with custom stuff. Here is an example line from a squid combined log: 1.1.1.1 - - [11/Dec/2010:03:41:46 -0500] "GET http://yourdomain.com:8080/en/some-page.html HTTP/1.1" 200 2142 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.1; C) AppleWebKit/532.4 (KHTML, like Gecko)" TCP_MEM_HIT:NONE I'd like to be able to parse n logs and output specific columns, for sorting, counting, finding unique values etc The main challenge and what makes it a little tricky and also why I feel this question hasn't yet been asked or answered, is the text qualification conundrum. When I spotted asql from the grep/awk question, I was very excited but then realised that it didn't support combined out of the box, something I'll look at extending I guess. Looking forward to answers, and learning new stuff! Answers doesn't have to be limited to platform or program/language. For the context of this question, the platforms I use the most are Linux or OSX. Cheers

• How Would I Restrict a Linux Binary to a Limited Amount of RAM?

  - by Ken S.

  I would like to be able to limit an installed binary to only be able to use up to a certain amount of RAM. I don't want it to get killed if it exceeds it, only that that would be the max amount that it could use. The problem I am facing is that I am running an Apache 2.2 server with PHP and some custom code that a developer is writing for us. The problem is that somewhere in there code they launch a PHP exec call that launches ImageMagick's 'convert' to create a resized image file. I'm not privy to a lot of details to the project or the code, but need to find a solution to keep them from killing the server until they can find a way to optimize the code. I had thought that I could do this with /etc/security/limits.conf and setting a limit on the apache user, but it seems to have no effect. This is what I used: www-data hard as 500 If I understand it correctly, this should have limited any apache user process to a maximum to 500kb, however, when I ran a test script that would chew up a lot of RAM, this actually got up to 1.5GB before I killed it. Here is the output of 'ps auxf' after the setting change and a system reboot: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 5268 0.0 0.0 401072 10264 ? Ss 15:28 0:00 /usr/sbin/apache2 -k start www-data 5274 0.0 0.0 402468 9484 ? S 15:28 0:00 \_ /usr/sbin/apache2 -k start www-data 5285 102 9.4 1633500 1503452 ? Rl 15:29 0:58 | \_ /usr/bin/convert ../tours/28786/.…. www-data 5275 0.0 0.0 401072 5812 ? S 15:28 0:00 \_ /usr/sbin/apache2 -k start Next I thought I could do it with Apache's RlimitMEM setting, but get the same result of it not getting limited. Here is what I have in my apache.conf file: RLimitMEM 500000 512000 It wasn't until many hours later that I figured out that if the process actually reached that amount that it would die with an OOM error. Would love any ideas on how to set this limit so other things could function on the server, and all of them could play together nicely.

• How can I stop Excel from eating my delicious CSV files and excreting useless data?

  - by atroon

  I have a database which tracks sales of widgets by serial number. Users enter purchaser data and quantity, and scan each widget into a custom client program. They then finalize the order. This all works flawlessly. Some customers want an Excel-compatible spreadsheet of the widgets they have purchased. We generate this with a PHP script which queries the database and outputs the result as a CSV with the store name and associated data. This works perfectly well too. When opened in a text editor such as Notepad or vi, the file looks like this: "Account Number","Store Name","S1","S2","S3","Widget Type","Date" "4173","SpeedyCorp","268435459705526269","","268435459705526269","848 Model Widget","2011-01-17" As you can see, the serial numbers are present (in this case twice, not all secondary serials are the same) and are long strings of numbers. When this file is opened in Excel, the result becomes: Account Number Store Name S1 S2 S3 Widget Type Date 4173 SpeedyCorp 2.68435E+17 2.68435E+17 848 Model Widget 2011-01-17 As you may have observed, the serial numbers are enclosed by double quotes. Excel does not seem to respect text qualifiers in .csv files. When importing these files into Access, we have zero difficulty. When opening them as text, no trouble at all. But Excel, without fail, converts these files into useless garbage. Trying to instruct end users in the art of opening a CSV file with a non-default application is becoming, shall we say, tiresome. Is there hope? Is there a setting I've been unable to find? This seems to be the case with Excel 2003, 2007, and 2010.

• Recommend a UK based VPS host equivalent to Dreamhost [closed]

  - by Pez Cuckow

  I appreciate this question could be considered subjective and argumentative so can people make recommendations rather than arguing about the best. I believe the "correct" answer is the one closest to what I am looking for. Basically I live in the UK but have been using the US based Dreamhost for about 6 years now, and my web projects are getting to the scale where the websites need to the UK based to cope with the demand and load. I originally had shared hosting with Dreamhost but upgraded to a VPS a while ago, getting 512mb of RAM, unlimited disk space, bandwidth and domains for $30. Their control panel is a custom easy to use build that they have created in house and offers features very similar to other web panels (as far as I am aware). So basically my question boils down to, is there anywhere that offers an equivalent package? In all honesty as long as I have over 50gb HDD space and unlimited domains it doesn't really matter? Are there any VPS providers you would recommend as reliable? I promise to check every link posted, many thanks for your time!

• Drowning in documents - recommend doc management solutions?

  - by Martin Day

  I've been researching document management lately. I want to organise my docs at home and also at the office. Finding affordable solutions one can actually test drive is quite hard. Some that I've downloaded just don't seem to work (testing on brand new Vista PC). I've seen some software on Amazon like Paperport but not really sure what they're like. For home I'd like something to organise files, full text search, good scanner integration, nice interface etc. But for the office it seems harder. I need something that does proper workflow and keeps versions. It will have an audit trail. Documents can be approved, checked in/out etc. I know a few clients who would like something similar. It would be great just to import thousands of documents from a shared drive and get them indexed with dupes killed. I'd like to be super clear about how/where the documents are being stored so that maintenance and backups are clear. My Google/twitter searches lead back to the same tired and vague webpages pushing what look like expensive and custom made solutions. Some might be very good I suppose but it's darn hard to tell. I don't mind a hosted package but all in all I don't think something like Google Docs, as good as it is now, will work. There are too many quirks and missing features (as compared to Office). Being able to work directly with the common Office file formats is important. I've noted a similar sounding question asked here back in August but it didn't seem to turn up too many solutions that I could easily and quickly apply. Also there could have been some changes since then so I feel it's worth asking.

• Looking for easiest, most simple solution to run a customised DNS Server for my local network on Windows 7.

  - by Jamie G

  I need to forward some websites, such as http://testing.server/ to an fixed IP address on my local network. I can do this easily on one computer using the hosts file. However, I need this to work for all machines on my network. I think the best way to do this will be to setup my own DNS Servers and add the custom DNS settings there. However, I'm looking for the simplest way possible to do this - I really don't want to spend hours setting up Unix Servers and running tricky terminal based scripts just to do this! My server is a standard Windows 7 machine. My dream would be a nice simple windows program with a GUI where I could input my ISP's DNS server and it would use those records, unless I had specifically set up my own DNS for a domain to use instead. If it had a web based admin system that was accessible from another computer on the network that would be even better. Does anyone know of anything that can do this? Many thanks indeed.

• Apache using 100% CPU, once again

  - by CBenni

  Recently, apache2 started using 100% of CPU power: top gives me From other, similar threads, I took the tip to use mod_status. Aside from HUGE amounts of NULL requests, it gives: CPU Usage: u2.16 s1.32 cu0 cs0 - .0835% CPU load 1.2 requests/sec - 17.6 kB/second - 14.6 kB/request 8 requests currently being processed, 42 idle workers The access and error logs do not show anything surprising or intriguing at all. Note the .8% CPU usage. Another tip was to use strace: root@server:~# strace -p 1956 Process 1956 attached - interrupt to quit restart_syscall(<... resuming interrupted call ...> And remains like this for at least half an hour, without producing any additional output. Restarting apache fixed the problem for less than a second The server runs a few custom python scripts aswell as a django-powered website on apache2 (up-to-date), but even turning the scripts off (or not having them active in the first place) did not change anything. After I stopped apache and powered my server off, powered it on a few minutes afterwards and restarted all my services, the CPU usage remained low for several hours, just in order to pop up again randomly (?) The DigitalOcean CPU stats on my server are: You can see how the CPU usage was super high for almost half a day until I restarted the bot - just to remain stable for several hours and then pop up again. I am completely at a loss of words and don't know what I could do to find out what piece of my code is giving me these problems or if apache itself is the cause... Therefore I would greatly appreciate any hints to the questions: What else can I try to do? Which things might I not have checked? Is this definitely in my own code? How do you find what part of python code crashes an app via a infinite loop or similar?

• how is the the linux console displayed to the user and how does the user go about changing the conso

  - by Chris

  I've been searching for the last two day on trying to understand how the console displays itself to the user and how to change the console settings. I've had some luck along the way but nothing that I've found has giving me a real clear explanation of how the console is displayed or how to change or control it's display settings. Some examples that of what I'm looking for are as follows: How is the console displayed on the screen? I know with X11 it uses your graphics card driver to display graphics to the screen, but how is the consoles text mode handled? Could some one ether explain this to me or point me to an in-depth overview of it all? Is it possible to have multi-head support in console mode with separate tty's on each screen? If so how would I go about setting this up? How would you go about changing the size of the console display from the default 80x25 to a custom size? I'm testing anything I find on a debian testing build, which is just the minimal base install on a virtual box. In time I will be using this information to setup my main system which is multi-head with 3 monitors. I would like to be able to support all three displays in console mode if possible.

• Win7 Hangs During App Install/Upgrade/Uninstall

  - by JadeMason

  I have a custom built PC that intermittently hangs when installing, uninstalling, or upgrading applications. Technical Specs ASUS P5E w/ WiFi Motherboard Intel Core2 Quad Q6600 Processor 4x 2GB G.Skill DDR2 800 SDRAM ASUS EAH2900XT / Radeon HD 2900XT 512MB Video Card Under normal operation the machine runs reliably, even under heavy load, such as video transcoding. The temperature never gets anywhere near where I would worry about it. However, the machine regularly hangs (complete lockup, no response to keyboard or mouse, no activity on-screen) when either installing a new application, uninstalling an existing application, or applying patches to existing applications or the OS. This is extremely frustrating as this machine is primarily used as a HTPC. Several apps are configured for automatic updates, and these updates sometimes cause the machine to lockup while we are watching content on the PC. In previously investigating this issue, I found one likely problem could be my Logitech Webcam. The Logitech software has a bug that leaves an entry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\SessionManager\PendingFileRenameOperations Which references the Temp directory. My registry contained this error, so I uninstalled the webcam software and deleted this registry key value. Unfortunately, the machine will still intermittently hang. I've noticed that the hangs always happen when an install/upgrade/uninstall requires elevated privileges (presumably to modify the registry). I can typically get at least one install/upgrade/uninstall to complete after a reboot, but after that it is a game of russian roulette to see if the operation will succeed or hang the machine. The event log is not helpful, as log messages end at the time of the hang, with no record of a warning or error. My only recourse when the machine hangs in this way is to perform a hard reset/power cycle. Any tips on how to further debug this issue are greatly appreciated.
