• md/raid:md2: cannot start dirty degraded array, kernel panic

  - by nl-x

  After having made use of a remote power switch, my server did not come back online. When I went to the datacenter and reboot the computer on the spot I see the server booting (I see the centos progress bar with running almost all the way to the end) and eventually giving the following messages: md/raid:md2: cannot start dirty degraded array. md/raid:md2: failed to run raid set. md: pers->run() failed ... md/raid:md2: cannot start dirty degraded array. md/raid:md2: failed to run raid set. md: pers->run() failed ... Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init not tainted 2.6.32-279.1.1.el6.i686 #1 Call Trace: [<c083bfbc>] ? panic+0x68/0x11c [<c045a501>] ? do_exit+0x741/0x750 [<c045a54c>] ? do_group_exit+0x3c/0xa0 [<c045a5c1>] ? sys_exit_group+0x11/0x20 [<c083eba4>] ? syscall_call+0x7/0xb [<c083007b>] ? cmos_wake_setup+0x62/0x112 The server runs CentOS and has software raid, and I don't have backups of the raid settings. The only backup I have is of /home and the database dumps. (Glad to at least have those though.) Since the server is an old Dell PowerEdge 1750 with no CD-ROM drive, I have no way of booting the machine from a boot disk. I also remember in the past that the server also wouldn't boot from a bootable USB disk. So the only way I know how to boot the server is to go to the datacenter, pick up the server and take it to the office. Screw open the server. Attach a cdrom drive to an IDE slot on the motherboard. And then boot it. I am hoping you guys could help me avoid this. I have looked a bit through the boot options and I found the following boot options. When CentOS is about to boot and interrupt the boot-countdown: CentOS (2.6.32-279.1.1.el63.i686) CentOS Linux (2.6.32-71.29.1.el6.i686) centos (2.6.32-71.el6.i686) I think the first configuration is the default one, because choosing that gets me to the above mentioned kernel panic. The other ones end with something like "Sleeping forever". I can press 'e' to edit boot commands, press 'a' to modify kernel arguments and press 'c' for grub command line. The command line gives a grub prompt. But I have no idea how to get the system to boot without (trying to) access the dirty partitions. What I want to do is off course: - boot the machine - check hard drive for errors - mark the drive as clean

• Server Cabinet/Room Cooling

  - by user37226

  Hello all. I currently have two desktops and three servers in my office sitting on the floor (I know this is bad). With that many servers the ambient temperature in the room goes up quickly. I am located in Dallas, TX so during the winter, if the heat is kept low, it is not a problem, but during the summer it easily jumps the room +10 degrees. I have decided and found a free 42U server cabinet that a hosting company was throwing away to house all of these systems in. One server is in a rack mount case while the other four servers are housed in mid-tower cases. I have purchased shelves for each computer and plan to lay the towers side ways on these shelves (as replacing the cases costs a heck of a lot of money). I like the idea of housing all of these systems in the cabinet because it will save a lot of room and clean up all of the cabling currently laying all over the office floor. When putting this setup together over the next couple of weeks, I want to address issues with dust and cooling. The server cabinet has a fan on top, front plexiglass door and a rear metal door with vent wholes on the bottom. First the cooling issues. I know I am going to want to have cool air enter the bottom of the cabinet and exit the top. I do not want the room heating up though as this will make my work area hot and then make the servers warmer as the air eventually reenters the cabinet. I had an idea to fix this problem, but am unsure if it will work. I was thinking of taking flexible piping and adapting it to the back fans of the computer having the other end of the pipe at the top close to the cabinet's top mounted fan. I was then thinking of creating a duct around the top fan into the attic. Now I am very concerned that the attic will cause issues with this type of setup because during July/August time frame, the attic is easily 120 degrees F. I could also use the flexible pipe to take it to an attic exhaust vent if it would be better to vent it into the 100 degree air outside (at least there may be wind. The other option would be to buy a small portable air conditioner. This may be a possibility, but do I want to spend the extra money on power? I bet this increases the noise. Plus they are around $250 on Amazon. What would you all recommend? Depending on the solution I end up running with above, I would also like to limit the dust that gets into the cabinet. If I were to cut a whole and mount a second cabinet fan on the bottom of the rear door, could I possibly mount a standard home air filter on the other side of that whole? Thanks in advance for your recommendations. I look forward to reading your interesting ideas.

• Unable to remove limit on memory usage for PHP script.

  - by Jess Telford

  The Situation I am having an issue with a PHP script getting the following error message: Fatal error: Out of memory (allocated 359923712) (tried to allocate 72 bytes) in /path/to/piwik/core/DataTable.php on line 969 The script I'm running is: /path/to/piwik/misc/cron/archive.sh I am assuming the numbers are Bytes, which means that total is approximately 360MB. For all intents and purposes, I have increased the memory limits on the server well above 360MB, yet this is the number (give or take a byte) it consistently errors out at. Please note: This question is not about fixing a memory leak in the script, nor about why the script itself is using so much memory. The script is part of the Piwik archiving process, so I cannot just fix any memory leaks, etc. For more info on this script and why I am increasing the memory limit, see "How to setup auto archiving" The question Given that the script is attempting to use over 360MB of memory, which I cannot change, why does it not seem possible for me to increase the amount of memory available to php on my server? What I've tried Increasing PHP's memory_limit Given the php.ini file: php -i | grep php.ini Configuration File (php.ini) Path => /usr/local/lib Loaded Configuration File => /usr/local/lib/php.ini I have edited that file, so the memory_limit directive reads; memory_limit = -1 Restart Apache, and check the new value has stuck; $ php -i | grep memory_limit memory_limit => -1 => -1 Run the script, and get the same error. I've also tried 1G, 768M, etc, all to the same result (ie; no change). Update 22nd June: Based on Vangel's help, I have attempted to set post_max_size to 20M in combination with setting memory_limit. Again, this has no effect. Removing the memory limit on child processes of Apache I have found and edited the httpd.conf file to make sure there is no RLimitMEM directive. I then used WHM's Apache Configuration Memory Usage Restrictions to generate a restriction, which it claimed was at 1000M (and confirmed by checking httpd.conf). Both of these resulted in no change to the script erroring at 360MB. Increasing the per process memory limits of Linux The current limits set on the system: $ ulimit -m 524288 $ ulimit -v 524288 I have attempted to set both of these to unlimited: $ ulimit -m unlimited $ ulimit -v unlimited $ ulimit -m unlimited $ ulimit -v unlimited Once again, this has resulted in absolutely no improvement in my problem. My setup $ cat /etc/redhat-release CentOS release 5.5 (Final) $ uname -a Linux example.com 2.6.18-164.15.1.el5 #1 SMP Wed Mar 17 11:30:06 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux $ php -i | grep "PHP Version" PHP Version => 5.2.9 $ httpd -V Server version: Apache/2.0.63 Server built: Feb 2 2011 01:25:12 Cpanel::Easy::Apache v3.2.0 rev5291 Server's Module Magic Number: 20020903:13 Server loaded: APR 0.9.17, APR-UTIL 0.9.15 Compiled using: APR 0.9.17, APR-UTIL 0.9.15 Architecture: 64-bit Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D HTTPD_ROOT="/usr/local/apache" -D SUEXEC_BIN="/usr/local/apache/bin/suexec" -D DEFAULT_PIDLOG="logs/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="logs/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="conf/mime.types" -D SERVER_CONFIG_FILE="conf/httpd.conf" Output of $ php -i: http://pastebin.com/EiRut6Nm

• Why would VMWare to go defunct? How to recover from/prevent it?

  - by Josh

  I am running VMWare Server 2.0.2 (Build 203138) on a dual core Intel i5 with Ubuntu Server 10.04 LTS system (kernel 2.6.32-22-server #33-Ubuntu SMP). Disk Subsystem is a software RAID5 array. The system has been set up for a little over a week. For the past 5 days I have been running at leat 3 VMs (Linux and a variety of Windows OSes) with no issues whatsoever. But while I was installing Linux onto a new VM, suddenly all VMs became unresponsive, including the one I was installing to. I could not log in to the VMWare Management Interface, and the system was somewhat unresponsive via SSH. When I looked at top, I saw: top - 16:14:51 up 6 days, 1:49, 8 users, load average: 24.29, 24.33 17.54 Tasks: 203 total, 7 running, 195 sleeping, 0 stopped, 1 zombie Cpu(s): 0.2%us, 25.6%sy, 0.0%ni, 74.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 8056656k total, 5927580k used, 2129076k free, 20320k buffers Swap: 7811064k total, 240216k used, 7570848k free, 5045884k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 21549 root 39 19 0 0 0 Z 100 0.0 15:02.44 [vmware-vmx] <defunct> 2115 root 20 0 0 0 0 S 1 0.0 170:32.08 [vmware-rtc] 2231 root 21 1 1494m 126m 100m S 1 1.6 892:58.05 /usr/lib/vmware/bin/vmware-vmx -# product=2; 2280 jnet 20 0 19320 1164 800 R 0 0.0 30:04.55 top 12236 root 20 0 833m 41m 34m S 0 0.5 88:34.24 /usr/lib/vmware/bin/vmware-vmx -# product=2; 1 root 20 0 23704 1476 920 S 0 0.0 0:00.80 /sbin/init 2 root 20 0 0 0 0 S 0 0.0 0:00.01 [kthreadd] 3 root RT 0 0 0 0 S 0 0.0 0:00.00 [migration/0] 4 root 20 0 0 0 0 S 0 0.0 0:00.84 [ksoftirqd/0] 5 root RT 0 0 0 0 S 0 0.0 0:00.00 [watchdog/0] 6 root RT 0 0 0 0 S 0 0.0 0:00.00 [migration/1] The VMWare process for the virtual machine I was installing into became a zombie. Yet, it was still consuming 100% of the CPU time on one of the cores, and I couldn't reach it or any other virtual machines. (I was logged in to one virtual machine over SSH, another via X11, and a third via VNC. All three connections died). When I ran ps -ef and similar commands, I found that the defunct vmware-vmx process had it's parent PID set to init (1). I also used lsof -p 21549 and found that the defunct process had no open files. Yet it was using 100% of CPU time... I was unable to kill any vmware-vmx processes, including the defunct one, even with kill -9. As a last resort to resolve the situation I tried to reboot the box, however shutdown, halt, reboot, and init 6 all failed to reboot/shutdown, even when given appropriate --force settings. ControlAltDel produced a message about rebooting on the console, but the system would not reboot. I had to hard power-cycle the box to resolve the situation. (See my other question, Should I worry about the integrity of my linux software RAID5 after a crash or kernel panic?) What would cause a scenario like this? What else could I have done to resolve it besides a hard reboot? What can I do to prevent such a situation in the future?

• Hardware recommendations / parts list for a modern, quiet ZFS NAS box - 2011-Feb edition [closed]

  - by dandv

  I want to build some really reliable storage for my data, and it seems that ZFS is the only filesystem at the moment that does live checksumming. That rules out DroboPro, so I'm looking to building a quiet ZFS NAS that would start with 4 2TB or larger hard drives. I'd like this system to be very reliable and relatively future-proof for 2-3 years, so I'm willing to invest some $$$ and buy higher end components. I did see questions here and on other forums about low-cost servers, but I'm not looking for those. I'd be super happy to go for an off-the-shelf solution, but I haven't found one that's quiet. I started doing the research (summarized on my wiki), but I realized that it just gets too complicated for what I know as a software dude, and I'm entering the analysis paralysis area. At this point, I'm basically looking for a parts list for a configuration that will work (and is modern), and I know there are folks around here who are way more competent than me. I've built computers and am comfortable assembling one and messing with *nix; I can follow guides; I just want to end the decision process for the hardware and software configuration. What I've researched so far (not that these are very modern components): Case: I think I've settled on the Antec Twelve Hundred case because it cools well, is quiet, and simply has 12 bays that allow elastic mounting. The SilverStone Raven is its counter-candidate, but I find its construction quite odd. For the PSU, I'm torn between Antec CP-850 and Nexus RX-8500, but I did this research more than a year ago. The Nexus has a very uniform power profile, and I'd rather not have the Antec spin up and down based on load. On the other hand, I'm not sure how often my file server will draw more than 400W under use. For the hard drives, I've read that WD Black drives are actually WD RE3 with a software setting changed. I'd also like to buy different drive types, not just 4 WDs. Recommendations? Right now I have a 2TB Hitachi Deskstar 7K300. For the motherboard, CPU and RAM I have no idea, other than the RAM must be ECC. I already asked a question here about ECC RAM, but I was misguided and was looking for a motherboard that would support USB 3.0 as well. I've learned to go with eSATA, or worry about USB later. Then there's the (liquid) cooling, Wi-Fi card, and FreeBSD vs. OpenSolaris Express. Lastly, I'm wondering if I can make this PC into a media server by adding a Blu-ray drive and a good sound card. But support for Blu-Ray is spotty on Linux, and I don't know if Windows 7 on VirtualBox would get sufficient hardware access to output HDMI or SPDIFF signals. (Running OpenSolaris virtualized is not an option because of the reliability risk.) Then there are HDCP concerns. Suggestions on that would be appreciated as well, but I don't want us to get sidetracked. A specific shopping list on the core components would be great, so I can start ordering, and in the meantime educate myself with regards to the other issues. Finally, I think this could become a great FAQ for those technically inclined to build their own ZFS server, but confused by the dizzying array of options out there, and I promise to compile the results and share my experience building and benchmarking the server.

• Can't re-mount existing RAID10 on Ubuntu

  - by Zoran

  I saw similar questions, but didn't find what solution to my problem. After power-cut, one of RAID10 (4 disks were) appears to be malfunctioning. I make tha array active one, but can not mount it. Always the same error: mount: you must specify the filesystem type So, here is what I have when type mdadm --detail /dev/md0 /dev/md0: Version : 00.90.03 Creation Time : Tue Sep 1 11:00:40 2009 Raid Level : raid10 Array Size : 1465148928 (1397.27 GiB 1500.31 GB) Used Dev Size : 732574464 (698.64 GiB 750.16 GB) Raid Devices : 4 Total Devices : 3 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Mon Jun 11 09:54:27 2012 State : clean, degraded Active Devices : 3 Working Devices : 3 Failed Devices : 0 Spare Devices : 0 Layout : near=2, far=1 Chunk Size : 64K UUID : 1a02e789:c34377a1:2e29483d:f114274d Events : 0.166 Number Major Minor RaidDevice State 0 8 16 0 active sync /dev/sdb 1 0 0 1 removed 2 8 48 2 active sync /dev/sdd 3 8 64 3 active sync /dev/sde At the /etc/mdadm/mdadm.conf I have by default, scan all partitions (/proc/partitions) for MD superblocks. alternatively, specify devices to scan, using wildcards if desired.

• CPU Utilization LAMP stack

• how to use ajax with json in ruby on rails

  - by rafik860

  I am implemeting a facebook application in rails using facebooker plugin, therefore it is very important to use this architecture if i want to update multiple DOM in my page. if my code works in a regular rails application it would work in my facebook application. i am trying to use ajax to let the user know that the comment was sent, and update the comments bloc. migration: class CreateComments < ActiveRecord::Migration def self.up create_table :comments do |t| t.string :body t.timestamps end end def self.down drop_table :comments end end controller: class CommentsController < ApplicationController def index @comments=Comment.all end def create @comment=Comment.create(params[:comment]) if request.xhr? @comments=Comment.all render :json=>{:ids_to_update=>[:all_comments,:form_message], :all_comments=>render_to_string(:partial=>"comments" ), :form_message=>"Your comment has been added." } else redirect_to comments_url end end end view: <script> function update_count(str,message_id) { len=str.length; if (len < 200) { $(message_id).innerHTML="<span style='color: green'>"+ (200-len)+" remaining</span>"; } else { $(message_id).innerHTML="<span style='color: red'>"+ "Comment too long. Only 200 characters allowed.</span>"; } } function update_multiple(json) { for( var i=0; i<json["ids_to_update"].length; i++ ) { id=json["ids_to_update"][i]; $(id).innerHTML=json[id]; } } </script> <div id="all_comments" > <%= render :partial=>"comments/comments" %> </div> Talk some trash: <br /> <% remote_form_for Comment.new, :url=>comments_url, :success=>"update_multiple(request)" do |f|%> <%= f.text_area :body, :onchange=>"update_count(this.getValue(),'remaining');" , :onkeyup=>"update_count(this.getValue(),'remaining');" %> <br /> <%= f.submit 'Post'%> <% end %> <p id="remaining" >&nbsp;</p> <p id="form_message" >&nbsp;</p> <br><br> <br> if i try to do alert(json) in the first line of the update_multiple function , i got an [object Object]. if i try to do alert(json["ids_to_update"][0]) in the first line of the update_multiple function , there is no dialog box displayed. however the comment got saved but nothing is updated. it seems like the object sent by rails is nil or cant be parsed by JSON.parse(json). questions: 1.how can javascript and rails know that i am dealing with json objects?deos ROR sent it a object format or a text format?how can it check that the json object has been sent 2.how can i see what is the returned json?do i have to parse it?how? 2.how can i debug this problem? 3.how can i get it to work?

• Determining the required depth and specifications for a server cabinet

  - by Bingu Bingme

  I'm trying to understand the considerations ("why") that go into determining the specifications ("what") for a rackmount server cabinet, in order to determine what sort of rack I should purchase for my home use. Since this is for home use, I won't be following certain best practices (eg. hot/cold aisle, not even air conditioning) and may be willing to sacrifice in various areas in order to reduce cost and footprint - but please advise if there are safety concerns or other considerations to note. The most basic specs for a server cabinet are the dimensions (external width x external depth x usable height). Width: commonly 600mm or 800mm (if the use case requires extra clearance around the sides, such as if there is lots of cabling). In my case and most common cases, I'm going to stick with 600mm. Height: Select a sufficiently tall rack to fit my equipment. But how much may I stuff into it? Eg, if there is a 15U rack, can I really populate it with 15U of servers, or should I leave 1U at top and bottom for air circulation? Depth: Racks commonly have external depth of 600mm (network equipment), 800mm, 1000mm, or even longer. I'm trying to see how to fit into the 800mm depth. With reference to http://www.server-racks.com/rack-mount-depth.html, I'm hoping to have the front and rear posts mounted ~ 28.5" (72cm) apart, which would leave only 8cm for front space and rear space. How much rear space (from rear posts to back of rack) do I really need? I won't use cable management arms, so can I mount a 72cm depth server since the power, KVM, network cables won't take up much depth? My most important equipment are all < 60cm depth (4U chassis) and should comfortably fit within the 800mm cabinet. The rest of the equipment are very old 1U servers that range from 65-72cm depth. I might still want to make further use of them, or I might discard them since they are so old. Even if the 72cm servers cannot be powered on in an 800mm rack, I should be able to use them as 1U shelves. But, what server depth can I expect to be able to operate? Or am I forced to upgrade to 1000mm depth racks in order to use any servers deeper than 60cm? With reference to best practices for HP racks, some other specs and installation considerations: There aren't any minimum recommendations for clearance on the sides of the rack. It is recommended to leave 48" front clearance. The 48" front clearance is based on 32" chassis depth, 13" to extend the rack rails and mate the inner/outer rails, and 3" for movement. If I don't use such rails (eg, use shelves instead), it should be sufficient to leave front clearance of chassis depth + 3". It is recommended to leave 30" rear clearance "to provide space for servicing the rack". I'm planning to back the rack into a corner of the room, and wheel it slightly out when I need to access the rear. If the wheeling plan is ok, I still need to know how much rear clearance is required for air circulation and ventilation purposes. Castor wheels and stabilising feet. Since I'm backing the rack into a corner of the room, I'll only be able to set the stabilising feet on the front corners. Thoughts on safety? The rack that I'm considering has front glass doors with side ventilation slits and fully perforated rear doors. I'm hoping this will be a good balance between temperature and noise (only ventilation slits facing out the front, while the rear is facing the walls). Or is the sound of high-rpm fans going to escape through the front slits anyway and destroy my sanity?

• How to diagnose and solve an erratic "HDCP Support Required"?

  - by Jom Orgstrom

  I am playing a digital tv broadcast on Windows Media Center for Windows 7. I built this system so it works with HDCP, and in fact I have been able to watch tv and bluray before with this same computer. However, I suddenly started getting an "HDCP Support Required" error from WMC. The entire message is as follows: HDCP Support Required High-bandwidth Digital Content Protection (HDCP) may not be supported by the current video card. Use an HDCP-compliant display, video card, and video driver. Or, connect using an analog connection such as component or VGA. Relevant specs are: CPU: Ivy Bridge Core i7-3770 Motherboard: Asus P8H77-I Memory: 16GB DDR3-1600 Graphics: Radeon HD 7850 (Driver by AMD, version 8.982.0.0 built on 2012/07/27) Display: Acer P243w connected by HDMI Sound: Roland Quad-Capture (It complains even when I use the bundled VIA HD Audio) TV Tuner: I-O Data GV-MC7/HZ3 OS: Windows 7 Professional SP1, Windows Update enabled. All patched and up to date. As you can see, there is nothing weird or old about my setup. I am also not doing anything strange, not doing any overclocking, weird system changes and so on. One thing that does happen from time to time, is that the display goes black for a few seconds (sometimes when watching media contents, sometimes when just using photoshop or Visual Studio). This happened with my previous setup as well, so I'd be inclined to think it is a display or cable issue (apart from the BD drive, these are the only things I kept from my previous setup to this one). But being a digital transfer, as far as I know, these things either work or not. Never erratically or with decreased quality. The thing is that sometimes I can watch the TV, sometimes not. This happens with recorded programs as well, so it's not a per-program thing. Sometimes rebooting helps, sometimes it doesn't. Sometimes unplugging and plugging back the HDMI connector helps, sometimes it doesn't. Sometimes doing so doesn't even turn the screen back on, so I have to reboot. Unfortunately, WMC's error message is quite unhelpful. I'd like to know exactly where the problem is, so I can solve it. I don't want to buy a brand new display just to then find out it was a registry setting that was misconfigured. I've tried looking at the system event viewer, but these errors don't show up at all in there. Other people who have this problem seem to have a setup that is not HDCP compliant, so I turn to you guys here. Anybody knows how to diagnose this problem? Edit: So I got the Cyberlink Blu-ray disc advisor. I ran it and told me everything was okay, except for the Video Connection Type, which showed as "Digital (without HDCP)". I then proceeded to unplug the power cable from the monitor, plugged it in again, ran the tool again, and now it's "Digital (with HDCP)". Needless to say, I can watch my TV and recorded programs on WMP again. I'm guessing that at some point, something may be slightly wrong with the HDCP setup, and Windows decides to reset the entire content protection path (which leads to the screen blanking out). Usually the reset succeeds, but sometimes it doesn't, so Windows defaults to turning HDCP off. There's no way to turn it back on, except by doing a hard reset of the display. I really want to know what the exact error was, so I can fix it. Is it the cable? is it the display? is it the video card? the driver? Also, is there any other way to try and turn HDCP on again without having to hard reset the display? Oh, questions, questions...

• How to diagnose computer lockups and freezes?

  - by Scott Mitchell

  I built a desktop computer a couple years back with the following specs: CPU: Intel Core 2 Quad Q9300 Yorkfield 2.5GHz 6 MB L2 Cache LGA 775 95W Quad-Core Processor BX80580Q9300 Motherboard: EVGA 122-CK-NF68-T1 LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard Video Card: Two EVGA 256-P2-N758-TR GeForce 8600GT SCC 256 MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card PSU: SeaSonic S12 Energy Plus SS-550HT 550W ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply Memory: Two G.SKILL 4 GB (2 x 2 GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ Since its inception, the machine has periodically locked up, the regularity having varied over the years from once a day to once a month. Typically, lockups happen once every few days. By "lockup" I mean my computer just freezes. The screen locks up, I can't move the mouse. Hitting keys on my keyboard that normally turn LEDs on or off on the keyboard (such as Caps Lock) no longer turn the LEDs on or off. If there was music playing at the time of the lockup, noise keeps coming out of the speakers, but it's just the current frequency/note that plays indefinitely. There is no BSOD. When such a lockup occurs I have to do a hard reboot by either turning off the computer or hitting the reset button. I have the most recent version of the NVIDIA hardware drivers, and update them semi-regularly, but that hasn't seemed to help. I am currently using Windows 7 x64, but was previously using Windows Server 2003 x64 and having the same lockup issues. My guess is that it's somehow video driver or motherboard related, but I don't know how to go about diagnosing this problem to narrow down which of the two is the culprit. Additional information re: cooling Regarding cooling... I've not installed any after-market cooling systems aside from two regular fans I scavenged from an older computer. The fan atop the CPU is the one that shipped with it. One of the two scavenged fans I added it located at the bottom tower of the corner, in an attempt to create some airflow from front to back. The second fan is pointed directly at the two video cards. SpeedFan installation and readings Per studiohack's suggestion, I installed SpeedFan, which provided the following temperature readings: GPU: 63C GPU: 65C System: 76C CPU: 64C AUX: 36C Core 0: 78C Core 1: 76C Core 2: 79C Core 3: 79C Update #3: Another Lockup :-( Well, I had another lockup last night. :-( SpeedFan reported the CPU temp at 38 C when it happened, and there was no spike in temperature leading up to the freeze. One thing I notice is that the freeze seems more likely to happen if I am watching a video. In fact, of the last 5 freezes over the past month, 4 of them have been while watching a video on Flickr. Not necessarily the same video, but a video nevertheless. I don't know if this is just coincidence or if it means anything. (As an aside, each night before bedtime my 2 year old daughter sits on my lap and watches some home videos on Flickr and, in the last month, has learned the phrase, "Uh oh, computer broke.") Update #4: MemTest86 and 3DMark06 Test Results: Per suggestions in the comments, I ran the MemTest86 overnight and it cycled through the 8 GB of memory 5 times without error. I also ran the 3DMark06 test without a problem (see my scores at http://3dmark.com/3dm06/15163549). So... what now? :-) Any further suggestions on what to check? Is there some way to get a stack trace or something when the computer locks like that? Resolution I have never did figure out the particular problems, but based on the suggestions here and elsewhere, I'm presuming it was a motherboard issue. In any event, I recently upgraded my system, buying a new motherbeard, PSU, CPU, and RAM, and that new rig has been working splendidly the past several weeks. I am using the same graphic cards as in the old setup, so I think it's safe to reason that they weren't the cause of the problem.

• How can I check if PHP was compiled with the UNICODE version of the Win32 API?

  - by Wesley Murch

  This is related to this Stack Overflow post: glob() can't find file names with multibyte characters on Windows? I'm having issues with PHP and files that have multibyte characters on Windows. Here's my test case: print_r(scandir('./uploads/')); print_r(glob('./uploads/*')); Correct Output on remote UNIX server: Array ( [0] => . [1] => .. [2] => filename-äöü.jpg [3] => filename.jpg [4] => test?test.jpg [5] => ??? ?????.jpg [6] => ?????????.jpg [7] => ???.jpg ) Array ( [0] => ./uploads/filename-äöü.jpg [1] => ./uploads/filename.jpg [2] => ./uploads/test?test.jpg [3] => ./uploads/??? ?????.jpg [4] => ./uploads/?????????.jpg [5] => ./uploads/???.jpg ) Incorrect Output locally on Windows: Array ( [0] => . [1] => .. [2] => ??? ?????.jpg [3] => ???.jpg [4] => ?????????.jpg [5] => filename-äöü.jpg [6] => filename.jpg [7] => test?test.jpg ) Array ( [0] => ./uploads/filename-äöü.jpg [1] => ./uploads/filename.jpg ) Here's a relevant excerpt from the answer I chose to accept (which actually is a quote from an article that was posted online over 2 years ago): From the comments on this article: http://www.rooftopsolutions.nl/blog/filesystem-encoding-and-php The output from your PHP installation on Windows is easy to explain : you installed the wrong version of PHP, and used a version not compiled to use the Unicode version of the Win32 API. For this reason, the filesystem calls used by PHP will use the legacy "ANSI" API and so the C/C++ libraries linked with this version of PHP will first try to convert yout UTF-8-encoded PHP string into the local "ANSI" codepage selected in the running environment (see the CHCP command before starting PHP from a command line window) Your version of Windows is MOST PROBABLY NOT responsible of this weird thing. Actually, this is YOUR version of PHP which is not compiled correctly, and that uses the legacy ANSI version of the Win32 API (for compatibility with the legacy 16-bit versions of Windows 95/98 whose filesystem support in the kernel actually had no direct support for Unicode, but used an internal conversion layer to convert Unicode to the local ANSI codepage before using the actual ANSI version of the API). Recompile PHP using the compiler option to use the UNICODE version of the Win32 API (which should be the default today, and anyway always the default for PHP installed on a server that will NEVER be Windows 95 or Windows 98...) I can't confirm whether this is my problem or not. I used phpinfo() and did not find anything interesting, but I wasn't sure what to look for. I've been using XAMPP for easy installations, so I'm really not sure exactly how it was installed. I'm using Windows 7, 64 bit - so forgive my ignorance, but I'm not even sure if "Win32" is relevant here. How can I check if my current version of PHP was compiled with the configuration mentioned above? PHP Version: 5.3.8 System: Windows NT WES-PC 6.1 build 7601 (Windows 7 Home Premium Edition Service Pack 1) i586 Build Date: Aug 23 2011 11:47:20 Compiler: MSVC9 (Visual C++ 2008) Architecture: x86 Configure Command: cscript /nologo configure.js "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack" "--disable-isapi" "--without-mssql" "--without-pdo-mssql" "--without-pi3web" "--with-pdo-oci=D:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8=D:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8-11g=D:\php-sdk\oracle\instantclient11\sdk,shared" "--enable-object-out-dir=../obj/" "--enable-com-dotnet" "--with-mcrypt=static" "--disable-static-analyze"

• Why does my computer run slowly and freeze sometimes?

  - by Brae

  EDIT I disabled sound in the BIOS, rebooted and it hung. I removed the (previously) faulty HDD, rebooted and it hung. I have managed to get my Realtek audio manager open again after its mysterious disappearance. Subsequently my microphone is now working again, to fix it I had to uninstall audio drivers, disable audio in BIOS, install audio drivers, enable audio in BIOS. Access via network (with faulty HDD in) seems to not be triggering hangs at the moment. I think with the sound problem fixed it might play a little nicer, but I think its still going to hang. If it does, then I'm fairly sure its been narrowed down to the mobo. EDIT Pretty convinced my motherboard is the culprit, because nothing else seems to have any obvious problems (bar the hard drive, which the PC still hangs without it being plugged in) So thank you all for helping, once I get more rep ill up a few of the answers. My PC is doing some weird things... Sometimes when I open up a program, lets say Adobe Photoshop, it will load everything normally, nice and quick no problems and I can use it fine. Other times its a little odd, and it loads the program as if it's only using half of the CPU. It's pretty obvious when it does it, normally the loading screen skims past, but when it does this weird load you see it slowly tick though each thing, and the program itself becomes incredibly slow. Even Google Chrome does it sometimes. Yet when I exit and reopen the program without doing anything else, it typically opens fine without lagging. I think this problem is probably a symptom of something bigger, because of other problems I'm having. Random hangs; no matter what I have open or what I'm doing. My PC will sort of freeze up for a few seconds. If music is playing it will either loop the last second or two, or it will buzz. This only lasts for a few seconds then it returns to normal without having to restart. During this time all programs lock up and freeze, and the mouse and keyboard are useless. I am also having a weird issue with my audio jacks, without touching my PC at all, sometimes I will see a popup saying that I have unplugged something or plugged something in, neither of which has actually happened. Pretty sure this is cause by the motherboard. I recently had a 'Pink Screen of Death' (yes pink) which pointed to my audio drivers. The lockups seem to happen with some consistency when someone is accessing my shared files via my home LAN. Which leads me to believe either one of my hard drives is acting up or more likely the controller. One of my drives had a bit of a crash before, I used Spinrite and managed to recover my stuff and now the drive appears to be working okay. This is possibly adding to the problems. My best guess is something has gone wrong with my motherboard, possibly a power issue or a chip has died, I really don't know. So what I would like to know is: Have I have missed some obvious diagnostic to help figure out what it is, or should I just bite the bullet and assume its my motherboard acting up and buy a new system? dxdiag[64-bit] - http://pastebin.com/G30kb2TL PSOD (minidump) - http://pastebin.com/aZsv0H56 HWiNFO64 (system info / specs) - http://pastebin.com/X6h3K8g6

• Computer not POSTing "randomly"?

  - by smoth190

  I have a custom built PC that is exhibiting some...odd... behavior, something I've never seen before. It was working fine one day, and the next day, it wouldn't start. Seeing as I wanted an upgrade anyway, I purchased a new motherboard that was compatible with all my parts. While replacing the motherboard, I accidentally damaged the CPU. Well, I wanted a new one anyway... so I got a new one. Seeing as I was replacing a ton of parts already, I bought a new PSU because the old one was super loud. When I slapped it all together, it starts up, lights, fans, drives, they all start. But I get no display from the monitor. No beeps, which I believe means it doesn't POST. I figured it was the RAM, because after removing the sound card and graphics card, there was nothing else that I hadn't replaced. When I remove both sticks of RAM, I get a continuous beeping, and according to the mobo handbook, means no RAM. So I think the mobo is functional, or atleast partly. I bought new RAM, but it still didn't work. I tried 3 monitors, with both VGA and DIV. So it's probably not the monitor, either. Now, let me get to the random part. Every 20 or so boots (I should also mention, for about 3 out of 5 boots I have to unplug the PC because it won't powerdown via the button), it will POST and I'll get display. Then, after about 2 or 3 resets, it won't work again. This confuses me so much, because even when I change nothing, it will/will not work. My thought is that maybe it has something to do with the RAM not clearing or something. I also reset the CMOS battery, incase that had anything to do with it, but no eval. I found some weird suggestion online about holding the power button for 30 seconds while it was unplugged. That did nothing, but I didn't expect it would... I've replaced just about the entire computer, and all the parts are compatible. Done about everything I can think of, but nothing has worked. Hopefully someone can help me here. And as I side note: When I do get my computer to boot, it says my hardware has changed and I have to re-activate windows. But it says I have to call Microsoft to do it. So I get this fancy automated voice that asks me to enter in a code into windows, then it asks me "How many computers have you activated with this copy of Windows?". Well, I had it on my computer before I replaced everything, so I said 1. Then he yelled at me for violating my 1-use license. I dunno what's going on there, do I have to re-purchase Windows 7? And they wonder why people pirate software... That's just a bonus question, though. Specs: 8GB of DDR2 RAM (Corsair) AMD CPU (I don't know what GHz or model because I can't find the box...

• MySQL reserves too much RAM

  - by Buddy

  I have a cheap VPS with 128Mb RAM and 256Mb burst. MySQL starts and reserves about 110Mb, but uses not more than 20Mb of them. My VPS Control Panel shows, that I use 127Mb (I also running nginx and sphinx), I know, that it shows reserved RAM, but when I reach over 128Mb, my VPS reboots automatically every 4 hours. So I want to force MySQL to reserve less RAM. How can i do that? I did some tweaks with my.conf but it helped not so much. top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1 root 15 0 2156 668 572 S 0.0 0.3 0:00.03 init 11311 root 15 0 11212 356 228 S 0.0 0.1 0:00.00 vzctl 11312 root 18 0 3712 1484 1248 S 0.0 0.6 0:00.01 bash 11347 root 18 0 2284 916 732 R 0.0 0.3 0:00.00 top 13978 root 17 -4 2248 552 344 S 0.0 0.2 0:00.00 udevd 14262 root 15 0 1812 564 472 S 0.0 0.2 0:00.03 syslogd 14293 sphinx 15 0 11816 1172 672 S 0.0 0.4 0:00.07 searchd 14305 root 25 0 7192 1036 636 S 0.0 0.4 0:00.00 sshd 14321 root 25 0 2832 836 668 S 0.0 0.3 0:00.00 xinetd 15389 root 18 0 3708 1300 1132 S 0.0 0.5 0:00.00 mysqld_safe 15441 mysql 15 0 113m 16m 4440 S 0.0 6.4 0:00.15 mysqld 15489 root 21 0 13056 1456 340 S 0.0 0.6 0:00.00 nginx 15490 nginx 18 0 13328 2388 992 S 0.0 0.9 0:00.06 nginx 15507 nginx 25 0 19520 5888 4244 S 0.0 2.2 0:00.00 php-cgi 15508 nginx 18 0 19636 4876 2748 S 0.0 1.9 0:00.12 php-cgi 15509 nginx 15 0 19668 4872 2716 S 0.0 1.9 0:00.11 php-cgi 15518 root 18 0 4492 1116 568 S 0.0 0.4 0:00.01 crond MySQL tuner: >> MySQLTuner 1.0.1 - Major Hayden <[email protected]> >> Bug reports, feature requests, and downloads at http://mysqltuner.com/ >> Run with '--help' for additional options and output filtering Please enter your MySQL administrative login: root Please enter your MySQL administrative password: -------- General Statistics -------------------------------------------------- [--] Skipped version check for MySQLTuner script [OK] Currently running supported MySQL version 5.0.77 [OK] Operating on 32-bit architecture with less than 2GB RAM -------- Storage Engine Statistics ------------------------------------------- [--] Status: -Archive -BDB -Federated +InnoDB -ISAM -NDBCluster [--] Data in InnoDB tables: 1M (Tables: 1) [OK] Total fragmented tables: 0 -------- Performance Metrics ------------------------------------------------- [--] Up for: 38m 43s (37 q [0.016 qps], 20 conn, TX: 4M, RX: 3K) [--] Reads / Writes: 100% / 0% [--] Total buffers: 28.1M global + 832.0K per thread (100 max threads) [OK] Maximum possible memory usage: 109.4M (42% of installed RAM) [OK] Slow queries: 0% (0/37) [OK] Highest usage of available connections: 1% (1/100) [OK] Key buffer size / total MyISAM indexes: 128.0K/64.0K [OK] Query cache efficiency: 42.1% (8 cached / 19 selects) [OK] Query cache prunes per day: 0 [!!] Temporary tables created on disk: 27% (3 on disk / 11 total) [!!] Thread cache is disabled [OK] Table cache hit rate: 57% (8 open / 14 opened) [OK] Open file limit used: 1% (12/1K) [OK] Table locks acquired immediately: 100% (22 immediate / 22 locks) [!!] Connections aborted: 10% [OK] InnoDB data size / buffer pool: 1.5M/8.0M -------- Recommendations ----------------------------------------------------- General recommendations: MySQL started within last 24 hours - recommendations may be inaccurate Enable the slow query log to troubleshoot bad queries When making adjustments, make tmp_table_size/max_heap_table_size equal Reduce your SELECT DISTINCT queries without LIMIT clauses Set thread_cache_size to 4 as a starting value Your applications are not closing MySQL connections properly Variables to adjust: tmp_table_size (> 32M) max_heap_table_size (> 16M) thread_cache_size (start at 4) I think if I do what MySQLtuner says, MySQL will use more RAM.

• Windows 7 is stuck at "Starting Windows" when I attempt to boot computer

  - by Eli

  Basically, whenever I turn on my computer, it gets to the Starting Windows phase and just stays there. The startup animation still plays, yet it gets nowhere. I have tried booting into safe mode, however it gets stuck at loading CLASSPNP.SYS. It then freezes there and doesn't continue booting. I have tried booting into recovery mode from the hard drive, and it freezes after displaying the background image. I have tried booting from a recovery CD, which works, and I was able to use system restore. However, using system restore did not fix it, and it still is stuck at the Starting Windows screen. I have tried booting a Windows CD (Windows 8 Retail Installer) to see if I could upgrade it to fix this issue, however that froze at a blank screen after it got past the boot logo. I have tried changing around the BIOS settings (including resetting), to no avail. I have tried re-plugging the internal PSU cables (this is a custom-built desktop), yet this has changed nothing. I can boot into a loopback Ubuntu install on the same drive, which works fine, other than the fact that it has issues with some of the USB ports and the network card. This system has worked fine for the past few months, completely stable, and nothing in the configuration has changed before this error started happening. Startup Repair on the Windows recovery CD doesn't find any issues. Unplugging my secondary hard drive or swapping around memory doesn't change anything. The hard drive itself is fine, it hasn't shown any signs of failure and once again, boots my other OS fine. If anyone could help with this, that would be great. I can't seem to find any possible solution to this. If it makes any difference, my system specs are as follows: AMD FX-8320 Gigabyte GA-970A-D3 4GB of DDR3 Radeon HD 6870 550w PSU I'd like to not have to reinstall Windows, for I have more than a terabyte of data that I would have to back up if that becomes the only option. EDIT: I have since tried the following: Tried the solution involving restoring files from RegBackup, which changed nothing. Tried testing everything with Hiren's boot CD, everything comes back as fine. Tried disabling everything unnecessary in the BIOS and unplugging everything unneeded, it still hangs. Tried swapping out every possible combination of RAM, it still has the same result. The RAM is not at fault it seems Tried every GPU I own (which is many!) and it still hangs at the exact same place. Tried minimizing the power consumption as much as possible, even using an old PCI graphics card. It still hangs at the same place in the same way, signifying that it's not the PSU at fault. Tried resetting the BIOS again, still nothing. Tried every possible combination of BIOS options, even downclocking everything, it still hangs in the same spot. Tried upgrading the BIOS from version FB to FD, which changed nothing. Based on this, I would conclude the motherboard to be at fault. Are there any other possibilities? I don't want to spend $150 for a new motherboard. EDIT 2: This is what it gets stuck at when I try to boot into safe mode: Note the slight graphical corruption at the top of the screen. No matter how I set up the system, this seems to be there. In addition, either it has stopped booting into safe mode now, or it takes upwards of 2+ hours, and I haven't left it running for that long.

• need assistance with my.cnf - 1500% CPU usage

  - by Alan Long

  I'm running into a few issues with our new database server. It is a HP G8 with 2 INTEL XEON E5-2650 processors and 32GB of ram. This server is dedicated as a MySQL server (5.1.69) for our intranet portal. I have been having issues with this server staying alive - I notice high CPU usage during certain times of day (8% ~ 1500%+) and see very low memory usage (7 ~ 15%) based on using the 'top' command. When the CPU usage passes 1000%, that is when the app usually dies. I'm trying to see what I'm doing wrong with the config file, hopefully one of the experts can chime in and let me know what they think.

• mySQL Optimization Suggestions

  - by Brian Schroeter

  I'm trying to optimize our mySQL configuration for our large Magento website.

• Connecting PC to TV via HDMI/DVI: Windows XP doesn't allow the appropriate screen resolution

  - by Jørgen

  I have a computer that is connected to the living room TV (a Panasonic) via HDMI. There is no other monitor connected. My problem is that the computer, which is running Windows XP, does not allow me to set the proper resolution for the TV. Both the graphics adapter and the TV should support the 1280x720 resolution, but it cannot be selected - the only available options are 1280x600 and 800x600, both in the "native" Windows dialog box and the custom Intel graphics options dialog box. Do anyone have a suggestion for a solution for this? Things I've thought of: Setting the resolution directly in the registry (where?) Installing some "custom" monitor driver (the TV manufacturer does not appear to provide any, currently the "generic" one is used) Details on the setup: Connection: DVI output on the computer via a passive DVI-HDMI adapter to the HDMI input on the TV, audio is run on a separate link, the TV is able to combine video and audio without any problem, the problem is there regardless of whether or not the audio is connected. The connection is several meters long through some walls, for this reason using a VGA cable instead is not an option. Note that the report explicitly says that the TV supports 1280x720. Still, I am not allowed to select it in Graphics Options, only 1280x600 and 800x600 is available. For 800x600, there's a lot of black around the edges; for 1280x600, the screen is "zoomed" so the edges of the monitor image (like the taskbar) is not visible. Other: The computer is running Windows XP. More recent versions of Windows are not an option (I have no licence). Linux is probably not an option (some of the video streaming sites I plan to use do not support it, I think) I wrote the rest of the details below. Thanks for any help!! TV: Panasonic TX-L32X10Y, European version; a 720p 32" quite "regular" LCD TV. Allowed resolutions according to manual: Signal name: 640x480 @60HZ Horizontal frequency: 31.47 kHz Vertical frequency: 60Hz Signal name: 750/720) /60p Horizontal frequency: 45.00 kHz Vertical frequency: 60Hz Signal name: 1,125 (1,080) / 60p Horizontal frequency: 67.50 kHz Vertical frequency: 60Hz (this is exactly how the manual presents it. PC via D-SUB (VGA cable) and "regular" HDMI have more alternatives.) Messing with the "zoom" settings on the TV does not affect the available resolution options on the computer. Computer: The following is a printout from one of the graphics adapter option pages. I think it covers most of it. The computer is a Dell.

• My 3D Games crashing in these scenarios

  - by desaivv

  I have a situation here which I am unable to solve. I bought a PC last year March, here are my specs: Intel Core i3 550 @ 3GHz 4 GB RAM @400 MHz XFX GeForce 9500 GT graphics card 1GB @550MHz 500 GB HDD Lately as soon as I load my save game of Skyrim, it crashes. I have been playing Skyrim since I joined Gaming.SE site. Crashes as in the entire scene gets red lines. I can not ALT + TAB back or even CTRL + ALT + DEL either. My only recourse is a hard reset via the power button. Can not take a screen shot either. I have the latest Forceware 296.10 drivers also. This has been happening since the last 2 weeks. I always use Driver Sweeper to clean my old drivers, since that is what XFXForce recommends before installing new drivers. I installed MSI Afterburner lately to see my GPU temperature. My GPU is default, never over-clocked it. In MSI's Afterburner, I can not adjust fan speed. It is greyed out. Also in settings there is no fan tab. With normal Internet browsing it stays at 51 C. Ran Memtest86 over night with level 11. Took about 13 hours, but no errors in my RAM. I even re-installed my OS, with just the 296 drivers. The fan for the GPU does come on. I can play Diablo 2. I can not get past Warcraft 3's menu selection. There WAS some dust in my machine, but I always try and keep everything clean, since in my home town dust is an issue. Always keep cool my entire PC cabinet. My friend came with his functioning graphics card, we bought our PCs at the same time with exact same specifications. His card did not work either. Same problem with the scene freezing with red lines. I did do my research before posting here. That is how I was able to learn about MSI Afterburner, Driver Sweeper, SpeedFan etc. I followed posts on Tom's Hardware too regarding people that had similar problems. One person suggested and was followed by worked as well the suggestion to "Bake the card in an oven". Since I bought it, played Diablo 2 for months, Starcraft 2 campaign for months and Skyrim recently for months. Bought ME3 also. I am at my wits end. I do not know what else to do. I can go out and buy a card, but my friend's card did not work either. I can use the machine for Eclipse or VS2010 development just fine. Just not with 3D gaming. I originally posted this question on Gaming.SE But I was directed here. I have browsed the SU database for my problem and found this, this, and this. But none of these cover my question. My machine is only one year old. Can some experienced superuser(s) shed some light on this scenario? Is it a 3D graphics card problem? Will a brand new card work? What else can I try to pin point the problem? Can it be the Motherboard? Thanks.

• Compiling program that uses libpcap on Mac OSX using iPhone 3.1.1 SDK for use on iPhone

  - by Alan

  Hey SOV users, I have a question that I'm hoping some iPhone Developers may be able to help with. I had a look at statically compiling a binary on my Mac and moving it over to the iPhone for execution. I have managed to get this bit of it working by installing the iPhone 3.1.3 SDK on my Mac and setting the architecture to the iPhone in the gcc line as follows; /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -I ~/Downloads/libpcap-1.1.1/pcap-compiled/ -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk -o test test.c I have managed to successfully compile a "Hello World" C program and executed it on the iPhone with success. e.g. include int main() { printf("Hello, World!\n"); return(0); } This worked a charm. I am also using 'ldid' to sign the application (but only if necessary). Anyways, I have been trying to get a program to compile which uses libpcap (http://www.tcpdump.org/) but with little success. I have downloaded and installed libpcap-1.1.1 on my mac and set the configure --prefix to /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/local and build the application. I then saw that the includes actually reside in Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/includes and so moved the Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/local/include files (which contained only the pcap stuff) to the correct location. I then attempted to compile the test program using; /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -I /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk/usr/include/ -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk -o pcap pcap.c -lpcap This worked a lot better than other tests but produces an error; i.e. ld: library not found for -lcrt1.o collect2: ld returned 1 exit status Do you have any ideas as to how I can do this successfully? I've tried a load of different things but none seem to be successful. Basically, I just want to install (or add) some headers to the existing iPhoneOS SDK for use in compiling programs. Any ideas? Cheers, A

• Runge-Kutta (RK4) integration for game physics

  - by Kai

  Gaffer on Games has a great article about using RK4 integration for better game physics. The implementation is straightforward but the math behind it confuses me. I understand derivatives and integrals on a conceptual level but I haven't manipulated equations in a long time. Here's the brunt of Gaffer's implementation: void integrate(State &state, float t, float dt) { Derivative a = evaluate(state, t, 0.0f, Derivative()); Derivative b = evaluate(state, t+dt*0.5f, dt*0.5f, a); Derivative c = evaluate(state, t+dt*0.5f, dt*0.5f, b); Derivative d = evaluate(state, t+dt, dt, c); const float dxdt = 1.0f/6.0f * (a.dx + 2.0f*(b.dx + c.dx) + d.dx); const float dvdt = 1.0f/6.0f * (a.dv + 2.0f*(b.dv + c.dv) + d.dv) state.x = state.x + dxdt * dt; state.v = state.v + dvdt * dt; } Can anybody explain in simple terms how RK4 works? Specifically, why are we averaging the derivatives at 0.0f, 0.5f, 0.5f, and 1.0f? How is averaging derivatives up to the 4th order different from doing a simple euler integration with a smaller timestep? After reading the accepted answer below, and several other articles, I have a grasp on how RK4 works. To answer my own questions: Can anybody explain in simple terms how RK4 works? RK4 takes advantage of the fact that we can get a much better approximation of a function if we use its higher-order derivatives rather than just the first or second derivative. That's why the Taylor series converges much faster than Euler approximations. (take a look at the animation on the right side of that page) Specifically, why are we averaging the derivatives at 0.0f, 0.5f, 0.5f, and 1.0f? The Runge-Kutta method is an approximation of a function that samples derivatives of several points within a timestep, unlike the Taylor series which only samples derivatives of a single point. After sampling these derivatives we need to know how to weigh each sample to get the closest approximation possible. An easy way to do this is to pick constants that coincide with the Taylor series, which is how the constants of a Runge-Kutta equation are determined. This article made it clearer for me: http://web.mit.edu/10.001/Web/Course%5FNotes/Differential%5FEquations%5FNotes/node5.html. Notice how (15) is the Taylor series expansion while (17) is the Runge-Kutta derivation. How is averaging derivatives up to the 4th order different from doing a simple euler integration with a smaller timestep? Mathematically it converges much faster than doing many Euler approximations. Of course, with enough Euler approximations we can gain equal accuracy to RK4, but the computational power needed doesn't justify using Euler.

• Very slow compile times on Visual Studio

  - by johnc

  We are getting very slow compile times, which can take upwards of 20+ minutes on dual core 2GHz, 2G Ram machines. A lot of this is due to the size of our solution which has grown to 70+ projects, as well as VSS which is a bottle neck in itself when you have a lot of files. (swapping out VSS is not an option unfortunately, so I don't want this to descend into a VSS bash) We are looking at combing projects (not nice, as we like the separation of concerns, but is a good opportunity to refactor away some dead wood). We are also looking at having multiple solutions to achieve greater separation of concerns and quicker compile times for each element of the application. This I can see will become a dll hell as we try to keep things in synch. I am interested to know how other teams have dealt with this scaling issue, what do you do when your code base reaches a critical mass that you are wasting half the day watching the status bar deliver compile messages UPDATE Apologies, I neglected to mention this is a C# solution. Thanks for all the cpp suggestions, but it's been a few years since I've had to worry about headers. At a distance I say I miss C++, but I'm not sure I want to go back EDIT: Nice suggestions that have helped so far (not saying there aren't other nice suggestions below, just what has helped) New 3GHz laptop - the power of lost utilization works wonders when whinging to management Disable Anti Virus during compile 'Disconnecting' from VSS (actually the network) during compile - I may get us to remove VS-VSS integration altogether and stick to using the VSS UI Still not rip-snorting through a compile, but every bit helps. Orion did mention in a comment that generics may have a play also. From my tests there does appear to be a minimal performance hit, but not high enough to sure - compile times can be inconsistent due to disc activity. Due to time limitations, my tests didn't include as many Generics, or as much code, as would appear in live system, so that may accumulate. I wouldn't avoid using generics where they are supposed to be used, just for compile time performance WORKAROUND We are testing the practice of building new areas of the application in new solutions, importing in the latest dlls as required, them integrating them into the larger solution when we are happy with them. We may also do them same to existing code by creating temporary solutions that just encapsulate the areas we need to work on, and throwing them away after reintegrating the code. We need to weigh up the time it will take to reintegrate this code against the time we gain by not having Rip Van Winkle like experiences with rapid recompiling during development.
