  • Unexpected results from custom partitioning scheme - Ubuntu preseed unattended install

    - by Mark Renouf
    Hi... I need some help with partman-auto custom recipe in preseed.... it's doing unexpected things, the docs aren't so clear. This is in my preseed file: d-i partman-auto/expert_recipe string \ boot-root-var :: \ 1024 100 1024 ext4 \ $primary{ } $bootable{ } \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext4 } \ mountpoint{ /boot } \ . \ 2048 50 4096 ext4 \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext4 } \ mountpoint{ / } \ . \ 4096 25 100000 ext4 \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext4 } \ mountpoint{ /var } \ . \ 256 75 100% linux-swap \ method{ swap } format{ } \ . Given an 80GB drive. I ended up with these partitions: / 2GB /boot 1GB /var 4GB swap 72GB What went wrong? What I want is: / 2GB /boot 1GB /var 72GB swap 4GB

  • Configuration setting of HttpWebRequest.Timeout value

    - by Michael Freidgeim
    I wanted to set in configuration on client HttpWebRequest.Timeout.I was surprised, that MS doesn’t provide it as a part of .Net configuration.(Answer in http://forums.silverlight.net/post/77818.aspx thread: “Unfortunately specifying the timeout is not supported in current version. We may support it in the future release.”) I added it to appSettings section of app.config and read it in the method of My HttpWebRequestHelper class  //The Method property can be set to any of the HTTP 1.1 protocol verbs: GET, HEAD, POST, PUT, DELETE, TRACE, or OPTIONS.        public static HttpWebRequest PrepareWebRequest(string sUrl, string Method, CookieContainer cntnrCookies)        {            HttpWebRequest webRequest = WebRequest.Create(sUrl) as HttpWebRequest;            webRequest.Method = Method;            webRequest.ContentType = "application/x-www-form-urlencoded";            webRequest.CookieContainer = cntnrCookies; webRequest.Timeout = ConfigurationExtensions.GetAppSetting("HttpWebRequest.Timeout", 100000);//default 100sec-http://blogs.msdn.com/b/buckh/archive/2005/02/01/365127.aspx)            /*                //try to change - from http://www.codeproject.com/csharp/ClientTicket_MSNP9.asp                                  webRequest.AllowAutoRedirect = false;                       webRequest.Pipelined = false;                        webRequest.KeepAlive = false;                        webRequest.ProtocolVersion = new Version(1,0);//protocol 1.0 works better that 1.1 ??            */            //MNF 26/5/2005 Some web servers expect UserAgent to be specified            //so let's say it's IE6            webRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322)";            DebugOutputHelper.PrintHttpWebRequest(webRequest, TraceOutputHelper.LineWithTrace(""));            return webRequest;        }Related link:http://stackoverflow.com/questions/387247/i-need-help-setting-net-httpwebrequest-timeoutv

  • Is it safe to disable nmi_watchdog?

    - by Rayne
    I'm using RHEL 6 (kernel 2.6.32-131) and I'm trying to start oprofile, but I keep getting an error. My oprofile version is 0.9.6-12. I was able to successfully do opcontrol --init But when I did a opcontrol --start --no-vmlinux I got the error Using default event: CPU_CLK_UNHALTED:100000:0:1:1 Error: counter 0 not available nmi_watchdog using this resource ? Try: opcontrol --deinit echo 0 > /proc/sys/kernel/nmi_watchdog I don't know if it's safe for me to do this? For what I googled, it seems that nmi_watchdog is used to reboot the system if it hangs, and that sounds like something I want. Also, grep NMI /proc/interrupts shows a bunch of numbers, which I guess indicates that nmi_watchdog is already running? How can I run both oprofile and nmi_watchdog?

  • Good experiences with bulk rate SMS providers?

    - by jen_h
    We're a pretty popular service, our users are currently sending 100000+ SMS messages (projected 180k this month, and continuing to grow) per month. We're currently using a primary domestic provider that doesn't provide bulk rates and doesn't provide short code access. We're using a few backup providers as well for max redundancy, but aren't thrilled by 'em. We're ideally looking for a service that provides good bulk rates/incentives, good uptime/redundancy/reputation, easy API-integration (including respectable error codes!) ;). Right now, we're looking primarily for a domestic US SMS solution, but aren't averse to using the same provider for both International & US. For those of you using bulk SMS right now - what are your recommendations, experiences, etc. in the bulk SMS domain? It sounds like I'm looking for a golden unicorn here, I know, but any data/recommendations/warnings you've got are helpful!

  • SFML programs fails to debug with glslDevil

    - by Zhen
    I'm testing the glslDevil debugger with a simple (and working) SFML application in Linux + NVidia. But it always fails in the window creation step: W! Program Start | glXGetConfig(0x86a50b0, 0x86acef8, 4, 0xbf8228c4) | glXGetConfig(0x86a50b0, 0x86acef8, 5, 0xbf8228c8) | glXGetConfig(0x86a50b0, 0x86acef8, 8, 0xbf8228cc) | glXGetConfig(0x86a50b0, 0x86acef8, 9, 0xbf8228d0) | glXGetConfig(0x86a50b0, 0x86acef8, 10, 0xbf8228d4) | glXGetConfig(0x86a50b0, 0x86acef8, 11, 0xbf8228d8) | glXGetConfig(0x86a50b0, 0x86acef8, 12, 0xbf8228dc) | glXGetConfig(0x86a50b0, 0x86acef8, 13, 0xbf8228e0) | glXGetConfig(0x86a50b0, 0x86acef8, 100000, 0xbf8228e4) | glXGetConfig(0x86a50b0, 0x86acef8, 100001, 0xbf8228e8) | glXCreateContext(0x86a50b0, 0x86acef8, (nil), 1) E!

  • LM Sensors always returning same (invalid) value for one temp sensor

    - by pkaeding
    I am trying to monitor the temp sensors on a server, and plot them using Cacti. I have lm-sensors installed and working correctly. For example, here is the output from sensors: % sensors acpitz-virtual-0 Adapter: Virtual device temp1: +26.8 C (crit = +100.0 C) temp2: +32.0 C (crit = +60.0 C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +36.0 C (high = +105.0 C, crit = +105.0 C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +42.0 C (high = +105.0 C, crit = +105.0 C) However, when I try to get this data via SNMP, I get only one sensor's temperature correctly, and another one always returns 100.000 C: % snmpwalk -Os -c public -v 1 10.8.0.18 -m ALL lmTempSensors lmTempSensorsIndex.1 = INTEGER: 0 lmTempSensorsIndex.2 = INTEGER: 1 lmTempSensorsDevice.1 = STRING: temp1 lmTempSensorsDevice.2 = STRING: temp1 lmTempSensorsValue.1 = Gauge32: 26800 lmTempSensorsValue.2 = Gauge32: 100000 So, my question is two-fold: Why is the second sensor that is returned by SNMP giving a value of 100 C (when it should be 32 C) Why are my CPU core sensors not being returned by SNMP?

  • Improve performance of bind9 service restart

    - by Jakob
    Hi, I'm setting up a name server hosting DNS for a large number of domains, 50,000 - 100,000 domains. I will be using Bind9 and the service will need to be restarted several times a day. I have made some tests and it seems that restart of the Bind9 service scales very poorly with the number of domains. #domains | restart time ----------------------- 10,000 | 3.1 sec 25,000 | 8.9 sec 50,000 | 50 sec 100,000 | 7:50 min Is there some way to speedup the restart of the service? I have noticed that restart only utilizes one core, is there some way for it to use more cores? The Bind9 version is 9.7.1-P2 with default configuration. The server running Bind9 is a Intel Core 2 Due 2.93 GHz with 4 GB memory and Ubuntu Server 10.10. Any help will be appreciated. Jakob

  • What techniques would you use for a next generation java web application?

    - by jakob
    I'm working at a site similar to Foursquare and Yelp, with approximately 100000 unique requests each week that generates content, growing steadily. We are currently using: Seam as Java web framework. MySQL as DB Hibernate as ORM Hibernate Search as Index EhCache for Caching. Since our site is slowly growing out of the current setup and has a lot of legacy code, it is time for us to start thinking about a major refactoring/changing setup. Web framework We are not ready to change the language but we are leaning towards Spring Web Framework, since: Seam is no more. Almost all of us have worked with Spring and liked it. DB and ORM We have done a little research and we are thinking about MongoDB. Index Do we need to have a separate Index if we use MongoDB? Cache ? So my question is basically: If you take Spring Web Framework and MongoDB into consideration, how would a good setup be for a web application that is growing and handles a lot of logged in users generating input and performing searches?

  • How can I move mysites to a new location

    - by Bob
    I recently restored my content and was instructed to create mysites in a different location than was originally used. Now I have several users mysites in /personal.

  • Estimate of Hits / Visits / Uniques in order to fall within a given Alexa Tier?

    - by Alex C
    I was wondering if anyone could offer up rough estimates that could tell me how many hits a day move you into a given Alexa rank ? Top 5,000 Top 10,000 Top 50,000 Top 100,000 Top 500,000 Top 1,000,000 I know this is incredibly subjective and thus the broad brush strokes with the number ranges... BUT I've got a site currently ranked just over 1.2M worldwide and over 500k in the USA (http://www.alexa.com/siteinfo/fstr.net) Pretty cool for something hand-built on weekends (pat self on back) I was applying to an ad-platform and was told that their program doesn't accept webmasters who have an Alexa rank of greater than 100,000. (Time to take back that pat on the back I guess). I know that my hits in the last 30 days are somewhere on the order of 15,000 uniques and 20,000 pageviews. So I'm wondering how much harder do I have to work to achieve my next "goals"? I'd like to break into the top million, then re-evaluate from there. It'd be nice to know what those targets translate into (very roughly of course). I imagine that alexa ranks and tiers become very much exponential as you move up the ranks, but even hearing annecdotal evidence from other webmasters would be really useful to me. (ie: I have a site that is ranked X and it got Y hits in the last 30 days) Thanks :) - Alex

  • How to automatically resume php-fpm?

    - by alfish
    I am using nginx+php-fpm on Debian Squeeze for a busy server and have had great difficulty to deal with maximum connections being reached. Here the problem is that php processes sometimes just die randomly under high load and leave the server with no php process. Then I need to manually restart php5-fpm service to bring back the server to life. I am wondering how to avoid this to happen, or at least treat the symptoms by restarting the php5-fpm automatically whenever there is not php process left to listen to incoming requests. My relevant configs are: pm = dynamic pm.max_children = 1400 pm.start_servers = 10 pm.max_spare_servers = 20 pm.process_idle_timeout = 1s; #not sure it will be useful when pm=dynamic pm.max_requests = 100000 request_terminate_timeout = 30 I appreciate your suggestions to cope with this nasty problem.

  • Bullet pattern isn't behaving as expected

    - by Fibericon
    I have a boss that's supposed to continuously shoot five streams of bullets, each at a different angle. It starts off just fine, but doesn't seem to want to use its entire array of bullets. No matter how large I set the length of bulletList, the boss simply stops shooting after a couple of seconds, then pick up again shortly. Here's what I'm using to generate the pattern: Vector3 direction = new Vector3(0.5f, -1, 0); for (int r = 0; r < boss.gun.bulletList.Length; r++) { if (!boss.gun.bulletList[r].isActive) { boss.gun.bulletList[r].direction = direction; boss.gun.bulletList[r].speed = boss.gun.BulletSpeedAdjustment; boss.gun.bulletList[r].position = boss.position; boss.gun.bulletList[r].isActive = true; break; } } direction = new Vector3(-0.5f, -1, 0); //Repeat with four similar for loops, to place a bullet in each direction It doesn't seem to matter if the bulletList length is 1000 or 100000. What could be the issue here?

  • Performance improvements of VBulletin by integrating the plugins

    - by reggie
    I have amassed quite a lot of plugins and code that is being hooked into VBulletin's plugin system. There are good uses for this system. But since I am now locked in with the VB 3 branch and it is no longer updated, I wonder what kind of performance improvements I would see if I integrated all the plugins into the vbulletin files and turned the plugin system completely off. My site has about 1.5 mio posts, about 100,000 threads, 100,000 members (of which 10,000 are "active"). I estimate I have about 200 plugins from different products in the plugin manager. Has anybody ever tried this move and could share the experiences?

  • When to use Nginx PHP Fast CGI with a TCP socket instead of a UNIX socket?

    - by user64204
    I've followed this guide to setup PHP in FastCGI mode with Nginx. This guide describes 2 ways of doing it: TCP socket and UNIX socket. I've ran some Apache Benchmark on my locale machine and here are the results: Below tests ran multiple times to get better average statistics: $ ab -c 200 -n 100000 http://.... APACHE: 1800 req/sec NGINX (TCP socket): 2500 req/sec NGINX (UNIX socket): 15000 req/sec As far as I understand, there is overhead with using a TCP socket rather than a UNIX socket, hence the better performance with the latter. However I was not expecting such a performance difference given that the TCP socket is on the localhost, and therefore would like to ask the following question: Q: Given the huge performance gain with using a UNIX socket, what are the configuration scenarios where it would make sense to use a TCP socket instead?

  • Apache CPU usage stays at 100% even when there are no requests

    - by Leirith
    Hi, I've been running the Apache HTTP server benchmarking tool (ab) on my new Apache server to test performance. I noticed that with a command like the following: ab -n 100000 -c 1000 http://www.mysite.com/ The CPU is used 100% by the apache2 processes during the testing. When the test concludes, usually with the following error just before the last requests are made: apr_poll: The timeout specified has expired (70007) Total of 99960 requests completed the CPU usage remains at 100%, and it's all being consumed by apache. I am using the worker MPM with and running PHP with mod_fcgid. Any advice as to why this is or what can be done to stop it would be appreciated.

  • How to copy/paste LARGE amounts of text in Windows

    - by Johnson
    I am not sure if this is more suited for Superuser or Stackoverflow, but here goes... A little bit of background: I'm learning SQL and was trying to make a very large table which I could use for optimization tests. Something generic with random values. I created a little Java program to do just that, and was able to put out a text file with 100,000 lines, each line being an SQL INSERT statement for a new random record. However, with anything much bigger than 100,000 lines, I had problems either opening/using the text file in any text editor, or copying/pasting the text to the windows clipboard and then into SQL Developer so I could execute it as a script. I'm probably overlooking something really obvious, or doing something really stupid. There has got to be a better way to do this, but I couldn't find anything through Google or Stackoverflow or Superuser. Thanks!

    consider a disk with a sector size of 512 bytes, 2000 tracks/surface, 50 sectors/track, 5 doubled sided platters, average seek time is 10 msec. Assume a block size of 1024-byte is selected. Assume a file that contains 100,000 records of 100-byte each is to be stored on the disk, and NONE of the reocd can be spanned 2 blocks. How many blocks are needed to store the entire file?? If the file is arranged sequentially on disk, how many surfaces are required?? Now, i have calculated that 10,000 blocks are needed to store 100,000 records. But i am not sure how to find out the answer of the surfaces required. I only calculated the capacity of track is 25KB and capacity of surface is 50,000 KB But I don't know how to calculate the number of surfaces... Could anyone help me how to get the answer? Thanks a lot!!

  • [C++] Producer/Consumer Implementation -- Feedback Wanted

    - by bobber205
    I'm preparing for an interview in a few weeks and I thougth I would give threads in boost a go, as well as do the simple producer/consumer problem I learned in school. Haven't done it quite awhile so I was curious what you guys think of this? What should I add to make it a better example etc. Thanks for the feedback! :) ////////////////////////////////////////////////////////////////////////// boost::mutex bufferMutex; deque<int> buffer; const int maxBufferSize = 5; ////////////////////////////////////////////////////////////////////////// bool AddToBuffer(int i) { if (buffer.size() < maxBufferSize) { buffer.push_back(i); return true; } else { return false; } } bool GetFromBuffer(int& toReturn) { if (buffer.size() == 0) { return false; } else { toReturn = buffer[buffer.size()-1]; buffer.pop_back(); return true; } } struct Producer { int ID; void operator()() { while (true) { boost::mutex::scoped_lock lock(bufferMutex); int num = dice(); bool result = AddToBuffer(num); lock.unlock(); //safe area done if (result) { cout << "Producer " << this->ID << " Added " << num << endl; } else { cout << "!!Buffer was Full!!" << endl; } //Added //Now wait boost::xtime xt; xtime_get( &xt, boost::TIME_UTC); xt.nsec += 1000000 + 100000 * (rand() % 1000); boost::thread::sleep(xt); } } }; struct Consumer { int ID; void operator()() { while (true) { int returnedInt = 0; boost::mutex::scoped_lock lock(bufferMutex); bool result = GetFromBuffer(returnedInt); lock.unlock(); //safe area done if (result) { cout << "\tConsumer " << this->ID << " Took Out " << returnedInt << endl; } else { cout << "!!Buffer was Empty!!" << endl; } //Added //Now wait boost::xtime xt; xtime_get( &xt, boost::TIME_UTC); xt.nsec += 1000000 + 100000 * (rand() % 1000); boost::thread::sleep(xt); } } }; void main() { Producer p, p2; Consumer c, c2; p.ID = 1; p2.ID = 2; c.ID = 1; c2.ID = 2; boost::thread thread1(boost::ref(p)); boost::thread thread2(boost::ref(c)); boost::thread thread3(boost::ref(p2)); boost::thread thread4(boost::ref(c2)); int x; cin >> x; }
