  • Fastest OS for Java applications

    - by user33408
    Hello I have a multithreaded Java program. I am dealing with certain perfomance problems. I have improved everything. Hardware + Software. Now I think that it's time to move to proper Operating System. I was wondering, what OS is the fastest for Java Virtual machine? I am using Sun Java6. Do you think that Sun Solaris would be the best choice for Java applications? Or FreeBSD? or CentOS (I am using it currently)? Thanks

  • What packages are safe to uninstall to reduce installation size?

    - by mathematician1975
    This question is similar to a previous question I asked How can I turn my desktop Ubuntu 8.04 into a command line only install?. I was wondering if anyone can recommend any other bulky packages from the standard 8.04 installation that can reduce the size on disk of my installation. All I really require is socket functionality, g++ and gcc, some kind of text editor and SSH client and server. Things that I don't require are things like media players, audio packages, and the more "superficial" kind of desktop niceties. Is there anything particularly large in a standard install that is safe for me to remove without compromising my requirements above? I am a bit apprehensive about trying to uninstall items and I am not totally confident about removal of particular things having a negative effect on the functionality of any other things I might need (an example is would it be safe for me to remove everything to do with Perl, or does the system/kernel/other processes require this) ??? Basically I would like to be left with the kind of items that would have been installed in the CLI version of 8.04 (had the alternative iso image not been faulty). Any help/suggestions would be gratefully received.

  • X crashes and GNOME loses all its configuration

    - by Oli
    About every 3 days on my desktop (always on), X crashes, gdm restarts and it dumps me at a login screen. When I log in Gnome appears to have lost a lot of its settings: it plays sounds in weird places, UI elements look like they're from the 90s (GTK+ defaults) and it's generally pretty hideous. Note everything works fine. It's not like my profile doesn't exist because I can browse the internet fine (Firefox knows my bookmarks, history, passwords, etc) and my desktop is unscathed (apart from the icon theme). Manually restarting gdm doesn't fix this. I have to do a full reboot. Now I'm almost certain that this is a nvidia issue causing X to baulk (I've seen similarish threads on nvnews) and I'm happy with that (my fault for running their latest drivers all the time). What I'm concerned about is why Gnome looks so fugly. Is there anything I can do to force it to reload its settings without restarting the whole computer. Restarting is an issue for me as I run several daemons that other computers on the network depend upon. This is what I mean by ugly/fugly... Look at that scroll bar!

  • Is Ruby on Rails supposed to have a steep learning curve or is it just me?

    - by Anita
    I'm a self-taught programmer. I've been learning RoR since October with varying intensity (sometimes all day, sometimes nothing for several weeks). Before that I knew only Java, but knew it pretty well. I've heard so much hype about RoR and how it's supposed to make you happy, productive, etc. So far it's only made me frustrated. I learned it out of the Agile book, and I suspect part of the difficulty might have to do with my not knowing JavaScript and CSS, and having only a shaky grasp of databases and HTML. But apparently it took me much longer to complete the project in the Agile book than other people, and I still don't remember much of it. There are some things about Rails that I just can't seem to get, e.g. when to use symbols and when NOT to, or how dynamic methods are called. Recently I was given a small Rails assignment where I'm asked to make a small change to the interface. It's taken me around 25 hours and although I've made some progress in understanding the code, I still have no idea how to proceed. I can't even ask Stack Overflow because there is so much code I'll have to provide to give context. So my question is in the title: is RoR supposed to take a long time to learn or am I just slow? Can it be that I've been learning from the wrong book? My learning style is such that I either understand nothing or understand everything, if that makes sense. Thanks!

  • Bug: unable to handle kernel NULL pointer dereference at

    - by maria
    I have recently installed new system on my disc, Ubuntu 12.04. Installation proceeded without problems, I started installing additional software and put data from other discs. I had already two times bug report, it was quite long, and I have no idea how to acces to log file (which probably is somewhere saved) and since I had to switch off the computer using the button, anything else was possible, here is just a small part of it (what I've noted on paper) could not write bytes: Broken pipe speach dicpatcher disabled: edit etc/default/speach-dispatcher saned disabled: edit .... and than: BUG: unable to handle kernel NULL pointer dereference at 0000009c I've run Memory test in GRUB, everything is fine. First time it occured when I was using rsync, second time when I was trying to install texlive. Should I install whole system once again? Or can it be hardware problem? Or something else? If there is any hardware details which may be relevant, please ask, since I have no idea what is happening, I don't know what kind of information could be useful. Thanks P.S. dmesg output:

  • Directing Multiple ccTLD's to 1 gTLD with a country specific subdirectory?

    - by Pascal Van Opzeeland
    We have multiple ccTLDomains and are thinking about how to best combine these into one. We want to do this to focus our link building efforts. We are running a website through which we offer a software-as-a-service. Therefore we could potentially sell to any country in the world. However, Germany is our most important market. We currently have a .com, .de, .nl. and .pl domain. All these domains have a high amount of unique content pages. What we are planning is to change everything to .com with language-based subdirectories, so .com/en/, .com/de/, etc. I have two questions concerning this issue: 1) How much of an advantage does a ccTLD have over a gTLD with country specific subdirectories in search rankings? So let’s say .de versus .com/de/? 2) How could we best redirect the visitors of our old ccTLD’s to our gTLD’s subdirectories? We would like to loose as few search engine rankings as possible. Thank you for your help.

  • Crackling sound from microphone recently, in 13.04

    - by Patrig Droumaguet
    I use 13.04 since the release and I use Skype which was working well. But recently I've had remarks saying my voice was "crackling", even if the voice from my interlocutor was perfect. Making a test with Audacity and Cheese, I've seen that every recorded sound (with the front microphone of my laptop or a jack microphone) was crackling. It's not really like saturating, the sound has a lot of annoying pops. I've tried to check the settings, they were still on PulseAudio. I've even tried the extreme solution : re-installing Ubuntu (because initially it was working)… with the same problem. If I boot on Windows (dual-boot) I have no problem (so it's not physical). If anyone could help :) My laptop is a HP dv6-6165sf. The sound card is a "IDT 92HD81B1X5" (with BeatsAudio). Thanks a lot ! New tests - july 6th Hi again, I've tried editing /etc/pulse/default.pa with these three settings : load-module module-udev-detect use_ucm=0 tsched=0 load-module module-udev-detect tsched=0 load-module module-udev-detect use_ucm=0 The three of them don't change anything, except the last one (which was by default) which makes Audacity record without any crackling sound. But in Skype, Cheese and Kazam, the sound is crackling… I've installed again Ubuntu 13.04 (from scratch, deleting everything from /home), and I've updated it. The microphone is still cracking. Thanks for your help !

  • More Tables or More Databases?

    - by BuckWoody
    I got an e-mail from someone that has an interesting situation. He has 15,000 customers, and he asks if he should have a database for their data per customer. Without a LOT more data it’s impossible to say, of course, but there are some general concepts to keep in mind. Whenever you’re segmenting data, it’s all about boundary choices. You have not only boundaries around how big the data will get, but things like how many objects (tables, stored procedures and so on) that will be involved, if there are any cross-sections of data (do they share location or product information) and – very important – what are the security requirements? From the answer to these types of questions, you now have the choice of making multiple tables in a single database, or using multiple databases. A database carries some overhead – it needs a certain amount of memory for locking and so on. But it has a very clean boundary – everything from objects to security can be kept apart. Having multiple users in the same database is possible as well, using things like a Schema. But keeping 15,000 schemas can be challenging as well. My recommendation in complex situations like this is similar to a post on decisions that I did earlier – I lay out the choices on a spreadsheet in rows, and then my requirements at the top in the columns. I  give each choice a number based on how well it meets each requirement. At the end, the highest number wins. And many times it’s a mix – perhaps this person could segment customers into larger regions or districts or products, in a database. Within that database might be multiple schemas for the customers. Of course, he needs to query across all customers, that becomes another requirement. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • How to configure a static wildcard subdomain with dnsmasq.

    - by Prody
    I have a network behind a NAT with a few machines. The machines are: router - NAT, dnsmasq, forwarding - directly connected to the inet server - which runs ssh, www and some other stuff clients - which do stuff on server I also have mydomain.com. server.mydomain.com is pointing to my connection's IP (single IP), which is the router, which forwards ports to server. Server, has a httpd running, which serves different sites based on vhosts. So I have site1.server.mydomain.com, site2.. The problem is that all the traffic is going thru the router, and when I check logs I always see the router's IP for everything (so it's hard to see who is running the script with the while(1)). I would just ServerAlias site1.server.local, but most of the sites have a root URL saved somewhere on top of which other URLs are built, so I can't do that. The solution for me would be telling dnsmasq somehow to answer to *.mydomain.com with server's IP. Is this possible somehow?

  • gtk2/mate apps are choppy on debian testing [migrated]

    - by b0ti
    I have recently upgraded to a core-i7 system and now all the apps from mate (GTK2 based) are very slow. Basically when I switch to a workspace that has a couple mate-terminals open, they are redrawn as if these were sent over the network. GTK3 apps and firefox work properly and are refreshed instantly. I'm running Debian testing. I have tried to reinstall xorg and related packages and everything seems to work fine except for this. Here is my xorg.log. Any hints?

  • XNA 3D coordinates seem off

    - by Peteyslatts
    I'm going through a book, and the example it gave me seems like is should work, but when I try and implement it, it falls short. My Camera class takes three vectors in to generate View and Projection matrices. I'm giving it a position vector of (0,0,5), a target vector of Vector.Zero and a top vector (which way is up) of Vector.Up. My Three vertices are placed at (0,1,0), (-1,-1,0), (1,-1,0). It seems like it should work because the vertices are centered around the origin, and thats where I'm telling the camera to look but when I run the game, the only way to get the camera to see the vertices is to set its position to (0,0,-5) and even then the triangle is skewed. Not sure what's wrong here. Any suggestions would be helpful. Just to make sure I've given you guys everything (I don't think these are important as the problem seems to be related to the coordinates, not the ability of the game to draw them): I'm using a VertexBuffer and a BasicEffect. My render code is as follows: effect.World = Matrix.Identity; effect.View = camera.view; effect.Projection = camera.projection; effect.VertexColorEnabled = true; foreach (EffectPass pass in effect.CurrentTechnique.Passes) { pass.Apply(); GraphicsDevice.DrawUserPrimitives<VertexPositionColor> (PrimitiveType.TriangleStrip, verts, 0, 1); }

  • Got root, now how should I configure my server?

    - by L. De Leo
    I've been a developer for years and by trade I had to know a little bit of server side configuration. But now I find myself needing to manage my own VPS instance (Amazon EC2) and I'm lost. I'd like to know what are the common ways to configure an Apache and MySQL server that is secure and efficient. For example right now I'm doing everything as root but I doubt that's the best way at all. My whole Apache is configured to serve 1 site when I'd like it to be able to serve multiple sites. Where do I start?

  • Cisco: changing VTP mode server/client to transparent

    - by J. Smith
    I have around 40 L2 switches (2960, 3560, 3500, 3750) running in VTP client mode and one L3 switch (6500) running in VTP server mode, all connected together. I would like to switch everything in VTP transparent mode without any interruption of service. I've already test on a poc version with 3 switches (Catalyst 2950, 3560 and 3750). Using serial and SSH connection, it is seems working but i'm not sure it is enough representative compare to the real network. Knowing that the VTP Pruning is enabled, I am wondering what would be the best procedure to proceed the changement. I've read that we could lost connection by keeping it enabled. Should I change the server or clients first? Is it important to change the VTP domain and VTP Pruning parameters?

  • Cygwin file and directory user and group

    - by dvanaria
    I use Cygwin as my main development environment on both my home and work computers. In order to share files between the two computers, I use Dropbox, which is installed in the following folder on both computers: c:\cygwin\home\dvanaria\dropbox Everything works great, except for one thing. When I'm working on my home computer and do an ls -l on any directory, all the files show up as owned by dvanaria of group Users. But when I work from my work computer, an ls -l shows all files as being owned by Administrators and of group Domain Users. I know Cygwin uses some kind of mapping between Windows users and permissions to the /etc/passwd file. But to be honest I have no idea how this file works or how it maps to Windows under Cygwin. Could anyone help figure this out? The main problem is that I can't edit any files when using my work computer, only read them.

  • How to change the download save directory in ktorrent from a remote host

    - by Garethj94
    So I have ktorrent running on a server and I don't have the ability to see the X11 display for the client, and I need to change my download directory since I like to keep everything very organized. So I need a way to change the download directory for the program as a whole, not like decide where to put each and every torrent that I download. This can't be done through the webui preferences so I'm guessing that I'll have to do it through ssh somehow but from what I've read there really isn't a command to use. Also the way that I have the application run is on startup my server runs the command ktorrent, so it will already be running when I want to change the download location so I assume that I will have to restart the program as well. If anyone knows how to do this it would be much appreciated, and I can't think that I'm the only person to want this feature.

  • Windows 7 Pro x64 suffering from insomnia

    - by gemisigo
    My Win 7 Pro x64 is unable to enter sleep mode. Pressing the sleep button results in strange state where the computer starts entering the sleep mode, the display is turned off but then the whole process stops, it does not switch off the hdd, the keyboard still responds to numlock/capslock, but the display does not on anymore. I have to cut power and restart. If I remove everything (wireless mouse, external hdd, usb hub, etc.) it does enter sleep mode, but if there is something left, it does not, though every one of them has "Allow the computer to turn off this device..." checked and "Allow this device to wake the computer" unchecked. Why does it not work? It was working properly in the RC.

  • SSH and Latent Connections (e.g., satellite connections)

    - by user71494
    Most of the week I live in the city where I have a typical broadband connection, but most weekends I'm out of town and only have access to a satellite connection. Trying to work over SSH on a satellite connection, while possible, is hardly desirable due to the high latency ( 1 second). My question is this: Is there any software that will do something like buffering keystrokes on my local machine before they're sent over SSH to help make the lag on individual keystrokes a little bit more transparent? Essentially I'm looking for something that would reduce the effects of the high latency for everything except for commands (e.g., opening files, changing to a new directory, etc.). I've already discovered that vim can open remote files locally and rewrite them remotely, but, while this is a huge help, it is not quite what I'm looking for since it only works when editing files, and requires opening a connection every time a read/write occurs. (For anyone who may not know how to do this and is curious, just use this command: 'vim scp://host/file/path/here)

  • Wireless slow, but very odd

    - by Logman
    I have a HP Pavilion dv6 laptop, internet through the wireless timeouts. Even though it connects fine to the AP/router. The computer had a virus (searchnu?) and I backed up the usual and restored the laptop to factory image. Problem is after the restore the internet through the wireless the same still... and connected via wired and everything worked fine. I was able to update the whole system. Internet worked perfect, speed great. But the wireless still was pitiful. Ping tests with wireless are interesting: Google= 18ms Gmail= 18ms Yahoo= 1023ms 8.8.8.8=30ms Microsoft= Request Timed Out Bing= Request Timed Out msn= Request Timed Out even though I get 18ms with google, the pages take a long time to load. Is this a root kit? is it the wireless card in the laptop?

  • Test JPQL with NetBeans IDE 7.3 Tools

    - by Geertjan
    Since I pretty much messed up this part of the "Unlocking Java EE 6 Platform" demo, which I did together with PrimeFaces lead Çagatay Çivici during JavaOne 2012, I feel obliged to blog about it to clarify what should have happened! In my own defense, I only learned about this feature 15 minutes before the session started. In 7.3 Beta, it works for Java SE projects, while for Maven-based web projects, you need a post 7.3 Beta build, which is what I set up for my demo right before it started. Then I saw that the feature was there, without actually trying it out, which resulted in that part of the demo being a bit messy. And thanks to whoever it was in the audience who shouted out how to use it correctly! Screenshots below show everything related to this new feature, available from 7.3 onwards, which means you can try out your JPQL queries right within the IDE, without deploying the application (you only need to build it since the queries are run on the compiled classes): SQL view: Result view for the above: Here, you see the result of a more specific query, i.e., check that a record with a specific name value is present in the database: Also note that there is code completion within the editor part of the dialog above. I.e., as you press Ctrl-Space, you'll see context-sensitive suggestions for filling out the query. All this is pretty cool stuff! Saves time because now there's no need to deploy the app to check the database connection.

  • VMware player suspends on screensaver

    - by Chad
    I have this problem with my VMWare player. When my host operating system either goes into screen saver or I lock the work station with Windows Key + L. VMWare player pauses or halts everything. So when i come back to the computer and there is a background task working inside the virtual machine it does not progress until i've actualy loged back on. Is there any way to stop this behaviour with VMWare player and keep it running in the background even when the screen saver or the work station is locked? Version of VMWare is: 3.0.0 build-203739

  • Completely formatting a USB flash drive

    - by efcjoe
    I have a Verbatim Store 'n' Go drive which by default comes with software in a partition which password protects the drive. I want to erase this partition, as it only works on Windows (I'm having to look at it now through a virtual machine on my Mac). I've tried using KillDisk to totally wipe the whole thing, but it doesn't seem to work, and this password-protecting partition always remains intact. Is there any program which will completely wipe a flash drive, no questions asked? Or is there a way to do it through the Verbatim software? I have the password and everything, I just can't find a way to fully format it. Cheers.

  • Desktop stops working in Windows 7

    - by Roger
    I'm having an odd problem on one of my Windows 7 machines. At machine startup, explorer.exe is working properly - I can use the Start menu, click on desktop icons, etc. At some later point, though, I lose the ability to interact with desktop icons. I can't double-click to open files on the desktop, and I can't right-click to see the properties window. Oddly enough the Start menu still works properly, and I can still open an Explorer window into my desktop and access everything. I can get around the problem by killing explorer.exe and restarting it using Task Manager, but it's annoying to have to do this over and over. Does anyone have any ideas? I took a look at startup files with msconfig and didn't see any obvious problems. Any suggestions would be appreciated.

  • Compilation of Etherpad fails in an OpenVZ VE

    - by ulf
    Hi everyone. I’m almost giving up, this will be my last try: I try to compile Etherpad on my OpenVZ server. It’s running a Debian 5.0 as the host system, in the VE I’ve got Ubuntu 10.04. I installed Etherpad in this VE with the instructions from the official Ubuntu Wiki: https://wiki.ubuntu.com/Etherpad. Everything runs fine until it comes to compilation. After calling bin/build.sh as described in the wiki the first steps are running fine. But then I’m running into a memory error: java.io.IOException: Cannot run program "cp": java.io.IOException: error=12, Cannot allocate memory Well, I understand the error message but don’t see the cause. The command free tells me that there’s plenty memory left in this VE: total used free shared buffers cached Mem: 2415236 1140872 1274364 0 0 0 -/+ buffers/cache: 1140872 1274364 Swap: 0 0 0 Beautiful. But even repeating the compilation process doesn’t bring me any further. Any help would be appreciated.

  • MAMP - Unable to turn off PHP E_STRICT error reporting

    - by Mark37
    For some reason, MAMP won't allow me to turn off E_STRICT warnings. I've tried everything from changing the value explicitly in php.ini to error_reporting(E_ALL & ~E_STRICT) in my file... to explicitly saying php_ini('error_reporting', E_ALL & ~E_STRICT). I'm entirely confused as to why this is happening, and from what I can tell its specific to MAMP. The version of MAMP I'm running is 5.2.13 - and before you start telling me I shouldn't be ignoring those warnings, lets just be clear that I am using a framework that requires that E_STRICT be ignored. (lame, I know.)

  • Rebooting an EC2 Instance

    - by ABrown
    I'm working on a project involving EC2 and I'm having a difficult time wrapping my head around this concept. With EC2 instances, will non-EBS backed volumes (standard EC2) survive a reboot of the OS? For example, I have an Ubuntu instance. If I type "/sbin/shutdown -r now", will I lose all data on the drive not in the AMI? I understand that if I terminate the instance via the tools or the control panel, I lose everything, but I can't find a concrete answer to the restart issue. An extra gold star goes to anyone who can link to documentation clearly explaining this. ;) Thanks for your time!
