• Web framework able to handle many concurrent users [closed]

  - by Jonas

  Social networking sites needs to handle many concurrent users e.g. for chat functionality. What web frameworks scales well and are able to handle more than 10.000 concurrent users connected with Comet or WebSockets. The server is a Linux VPS with limited memory, e.g. 1GB-8GB. I have been looking for some Java frameworks but they consume much memory per connection. So I'm looking for other alternatives too. Are there any good frameworks that are able to handle more than 10.000 concurrent users with limited memory resources?

• re-point LM to a new vCenter (share same database)

  - by CapiZikus

  1) I'm planning to create a new vCenter server which database point to the same db as current vCenter (the one LM pointing to atm), Then I'm planning to repoint the LM to a new vCenter, ( the new one will see the same esx host, datastore, etc) Is LM will be okay if I do this? 2) The currect VC is a dediated server and a new vCenter will be VM, the current vCenter has database installed on local machine (inc update manager as well) I'm planning to move the local db to cluster db then point the current vCenter to this new cluster and make sure everything is working before promote a new one. Update manager will also has it own VM and point to a new db cluster. Is anythingelse I miss out or need to pay more attention on? thanks

• SLI Artifact issues

  - by sloughk

  When I enable SLI I keep getting artifacts in random games and in Windows Aero sometimes . It doesn't seem to be about over-heating as it happens randomly, and sometimes whole computers just crashes (not blue-screen, just black gone...) My setup: Geforce 8800 GTS 320MB ( http://www.bfgtech.com/bfgr88512gtoce.aspx ) x 2 GIGABYTE EX58-UD4 Windows 7 RC PSU 800W I've got the latest NVIDIA drivers and F5 BIOS update (*SLI update*). When I disable SLI and use the cards separately they are working just fine even in games. Any idea why this might happen?

• Is MediaTemple's (gs) really worth the hassle? [closed]

  - by Andrew

  I have been hosting my sites with Dreamhost for a while, and although none of them are high-trafic atm, I am going to a launch a Rails app this summer and a couple of other stuff, so I need a serious host. Since my plan ends in a couple of days, I have been looking at alternatives, and because MT has such a good reputation in the webdesign world, I have been seriously considering paying the ridiculous 20$/month for its shared hosting services. That was until I actually read some reviews of it, most of which indicated it is slow and overpriced. So now I'm wondering whether switching over to (gs) would really be a good idea, or if I would be better off paying less money for something like a Site5 or Hostgator shared hosting plan. What is your experience with MT, and particularly their Grid Service? Do you think I should even switch to (gs) in the first place, or should I choose something else from its competitors?

• 2D Collision masks for handling slopes

  - by JiminyCricket

  I've been looking at the example at: http://create.msdn.com/en-US/education/catalog/tutorial/collision_2d_perpixel and am trying to figure out how to adjust the sprite once a collision has been detected. As David suggested at XNA 4.0 2D sidescroller variable terrain heightmap for walking/collision, I made a few sensor points (feet, sides, bottom center, etc.) and can easily detect when these points actually collide with non-transparent portions of a second texture (simple slope). I'm having trouble with the algorithm of how I would actually adjust the sprite position based on a collision. Say I detect a collision with the slope at the sprite's right foot. How can I scan the slope texture data to find the Y position to place the sprite's foot so it is no longer inside the slope? The way it is stored as a 1D array in the example is a bit confusing, should I try to store the data as a 2D array instead? For test purposes, I'm thinking of just using the slope texture alpha itself as a primitive and easy collision mask (no grass bits or anything besides a simple non-linear slope). Then, as in the example, I find the coordinates of any collisions between the slope texture and the sprite's sensors and mark these special sensor collisions as having occurred. Finally, in the case of moving up a slope, I would scan for the first transparent pixel above (in the texture's Ys at that X) the right foot collision point and set that as the new height of the sprite. I'm a little unclear also on when I should make these adjustments. Collisions are checked on every game.update() so would I quickly change the position of the sprite before the next update is called? I also noticed several people mention that it's best to separate collision checks horizontally and vertically, why is that exactly? Open to any suggestions if this is an inefficient or inaccurate way of handling this. I wish MSDN had provided an example of something like this, I didn't know it would be so much more complex than NES Mario style pure box platforming!

• Can I use wildcards is puppet package ensure to cover multiple releaseversion

  - by Rob van den Eijnde

  Using puppet I want to update packages on my (CentOS 5 & 6 servers) in a controlled way. Therefore I don't want to use ensure=>latest but rather ensure=>3.0.1-1. Example: class puppet::installation inherits puppet { package { "puppet": ensure => "3.0.1-1", } } The update works alright but puppet agent keeps complaining that there is a difference: /Stage[main]/Puppet::Installation/Package[puppet]/ensure: current_value 3.0.1-1.el6, should be 3.0.1-1 (noop) I can solve this by changing the ensure rule to 3.0.1-1.el6 but than that won't work on CentOS 5. Is there a short/clean way to solve this or do I have to write to seperate, os-releaseversion dependant rules. I have been googling for a solution but didn't find anything pertaining to this particular question. Any suggestion or reference to a relevant example would be appreciated.

• Blogging from Office RT

  - by Dennis Vroegop

  During the last Build conference all attendees were given a brand new sparkling exciting Surface RT device (I love that machine despite its name but that's beside the point). On it came a version of Office 2013 RT, or better: the preview version. Now, I translated that term "Preview" to "Beta". Which is OK, since I've been using a lot of beta products from Microsoft and they all were great. And then I wanted to post a blogposting from Word. I knew I could, I have been doing this for a long time (I prefer Live Writer but that isn't available on Windows 8 RT). So I wrote the entry and hit "Publish". Instead of my blogsite I got a nice non-descriptive error telling me I couldn't post. So I fired up my other (Intel based) Win8 tablet, opened Word RT Preview, it loaded my blogpost (you've got to love the automatic synchronization through Skydrive) and tried from that machine. Same error. So, I installed Live Writer (remember, the other machine is Intel based) and posted from there. That worked like a charm. Apparently, there was something wrong with Word. I gave up and didn't think about it anymore. Yet… what you're reading now is written in Word 2013 RT on my Surface RT. So what did do? Simple: I updated from the Preview version to the final version. That's all there was to it. So…. If you're still on the preview I urge you to upgrade. You need to go to the "classic desktop update" window instead of going through the Windows Store App style update since Office is a desktop system, but once you do that you'll have the full version as well. Happy blogging!

• Cannot see boot options after editing grub background

  - by cipricus

  After solving this problem I managed to get myself into truble again out of nothing by trying to change the display of the dual boot option page in Boot Customizer. I have changed the background, the fonts size (I have increased them) and font style (I have chosen UnDotum). But Boot Customizer gave me an error (I mean a message that the application was closed unexpectedly or smth). I have restarted BootCustomizer and the settings were there. When I rebooted, instead of the normal boot options list, just the background image that I had selected and nothing else. I used Boot Repair to repair grub, it says it did it successfully, but I still get the background image when I try to boot. Any ideas? (Could it be the matter that I chose UnDotum font style? That was installed in Lubuntu - but how could it be accessible in displaying boot options?) The contents of etc/default/grub are: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" I have tried to modify etc/default/grub: GRUB_HIDDEN_TIMEOUT=0 to 10 GRUB_HIDDEN_TIMEOUT_QUIET=true to false and GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to "" but it doesn't help Also, using Shift doesn't make the list visible.

• OpenGL programming vs Blender Software, which is better for custom video creation?

  - by iammilind

  I am learning OpenGL API bit by bit and also develop my own C++ framework library for effectively using them. Recently came across Blender software which is used for graphics creation and is in turn written in OpenGL itself. For my part time hobby of graphics learning, I want to just create small-small movie or video segments; e.g. related to construction engineering, epic stories and so on. There may be very minimal to nil mouse-keyboard interaction for those videos, unlike video games which are highly interactive. I was wondering if learning OpenGL from scratch is worth for it or should I invest my time in learning Blender software? There are quite a few good movie examples are created using Blender and are shown in its website. Other such opensource cross platform alternatives are also welcome, which can serve my aforementioned purpose.

• install PECL JSON in PHP 5.04

  - by Radu Maris

  It's OK (compatible) to install PECL native JSON (from here) in PHP 5.0.4, on a production server running FC4 where unfortunately I cannot update PHP to at least 5.2 ? If there is a good chance to screw up PHP instalation on the server, I will not try to install it, and I will stick to Service JSON ( http ://svn.php.net/viewvc/pear/packages/Services_JSON/trunk/ ) In documentation ( http ://aurore.net/projects/php-json/ ) I have found: A simple ./configure; make; make install should do the trick. Make sure to add an extension=json.so line to your php.ini/php.d. (but I can't find anythink about compatible versions of PHP) Thank you. (Please don't tell me to update the OS and PHP, beacause it's not my decision :( )

• How can I install an Apple Magic Trackpad on a PC without Boot Camp?

  - by rymo

  I have a Apple Magic Trackpad and I'd like to use it with my PC. I have no other Apple hardware besides the Trackpad. I do not have OSX and thus no Boot Camp CD. The Trackpad uses Bluetooth and will pair with Windows 7 without specific drivers (appears as an HID-Compliant Mouse), but all it will do is point and left click (physical click, no touch tap). With Apple's Windows driver update, I should be able to achieve: Tap to click Dragging Drag lock Secondary click Two-finger scrolling Two-finger secondary tap/click But how can I obtain this driver without Boot Camp installed? Apple's Boot Camp update EXE will not install on my PC (non-Apple hardware).

• Indexing File Contents

  - by Rafid K. Abdullah

  People seem to have already asked about indexing file system: What options are there for indexing my filesystem? Alternatives to OS X's Spotlight? but I want to actually just index a certain working directory and be able to do that manually (so that I make sure my search is correct). Basically, I am on working a project and I need be able to search in contents quickly. I already use 'locate' and 'updatedb' commands, but those search for file names only. I am looking for similar commands but file contents. Just in case you are wondering why I don't use tracker also like answered in the two posts, tracker have a set of prespecified folders to search in them, and whenever you make a search, you search in all of them. What I want is to be able to search in every project separately.

• Modernising settings, packages

  - by Sam Brightman

  The update manager (possibly combined with the janitor) does a reasonable job of bringing packages up to date with a new release, removing ones that are replaced by different projects etc. However, I'm left with the lingering feeling that quite a few settings are lingering from old releases. For example, some packages may be left around that I installed myself whereas now the functionality is provided by default. Another example is that my user doesn't get the new theme, and the panel bar is a mess. I can compare against an inactive user on the same system: everything seems tidier. There are also things like the explosion of System Preferences, user groups (inactive user, more recently created, is in groups that the older, active user isn't). In other areas (e.g. default font) I do seem to get given the new defaults. Another example is Spotlight-equivalent search. I remember Beagle and Tracker, I remember removing tracker when it used all system RAM and swap for 2 entire release cycles, but I don't know what I'm "supposed" to be using now. Is there even a default indexing-search installed and exposed? aptitude install ubuntu-desktop doesn't do anything, so the basics are in place package-wise. Is there any way to update my settings to the modern "Ubuntu way" without reinstalling from scratch? Can I do so selectively i.e. show the differences? Most of the time package management on Linux is an absolute joy compared to the alternatives, but if the desktop gets messed up after only a release or two, we're back to reinstalling just like Windows.

• Static IP configuration causing apt-get errors

  - by JPbuntu

  I am getting errors when running apt-get update or when installing new packages. Although this only happens when the server configured for a static IP address. Changing the configuration back to DHCP and restarting networking fixes the problem, although I want a static IP. Once it is working I can change back to my static IP address and restart networking. Although this only works until I restart the server (restarting the router is ok), and then I start getting the same errors and have to switch back to DHCP. Any ideas on what could be causing this or tips on troubleshooting it? Thanks in advance. here is my static IP configuration: auto eth0 iface eth0 inet static address 192.168.2.2 netmask 255.255.255.0 gateway 192.168.2.1 The apt-get update errors go something like this: A few of these Ign http://us.archive.ubuntu.com precise-backports InRelease then a lot of these Err http://security.ubuntu.com precise-security Release.gpg Something wicked happened resolving 'security.ubuntu.com:http' (-5 - No address associated with hostname) and a lot of these W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise-backports/universe/i18n/Translation-en Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname)

• Software design of a browser-based strategic MMO game

  - by Mehran

  I wonder if there are any known tested software designs for Travian-like browser-based strategic MMO games? I mean how would they implement the server of such games or what is stored in database and what is stored in RAM? Is the state of the world stored in one piece or is it distributed among a number of storage? Does anyone know a resource to study the problems and solutions of creating such games? [UPDATE] Suggested in comments, I'm going to give an example how would I design such a project. Even though I'm not sure if I'm proposing the right one. Having stored the world state in a MongoDB, I would implement an event collection in which all the changes to the world will register. Changes that are meant to happen in the future will come with an action date set to the future and those that are to be carried out immediately will be set to now. Having this datastore as the central point of the system, players will issue their actions as events inserted in datastore. At the other end of the system, I'll have a constant-running software taking out events out of the datastore which are due to be carried out and not done yet. Executing an event means apply some update on the world's state and thus the datastore. As scalable as this design sounds, I'm not sure if it will be worth implementing. For one, it is pointless to cache the datastore as most of updates happen once without any follow ups. For instance if you have the growth of resources in your game, you'll be updating the whole world state periodically in which case, having incorporated a cache, you are keeping the whole world in RAM (which most likely is impossible). So can someone come up with a better design?

• 404 Error on a file that exists?

  - by Abs

  Hello all, A script makes a GET request to my URL like so: http://mydomain.com/cgi-bin/uu_ini_status_audios.pl?tmp_sid=b742be1d131c4d32237a9f1fcdca659e&rnd_id=0.2363453360320319 However, I get a 404 returned straight away: The requested URL /cgi-bin/uu_ini_status_audios.pl was not found on this server. But that script exists on my server, I can see the file! It has the correct permissions (I gave it a 777 to be sure). It is also owned by my apache user and its in the group apache. What am I missing?? Thanks for any help on this! Update I thought it would have been a htaccess (rewrite) but I don't think it is anymore. I tried putting a index.php file in there and try to access it via my URL but I can't even do that! I tried this: http://mydoamin.com/cgi-bin/index.php - same 404 error! I get this in myerror log: [Tue Sep 14 14:42:49 2010] [error] [client xx.xxx.xx.xxx] script not found or unable to stat: /var/www/vhosts/mydomain.com/cgi-bin Access_log file: xx.xxx.xx.xxx - - [14/Sep/2010:14:48:25 +0200] "GET /cgi-bin/index.php HTTP/1.1" 404 475 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.9) Gecko/20100824 Firefox/3.6.9 (.NET CLR 3.5.30729)" Update 2 My htaccess file: <IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^blog/ - [L] RewriteCond %{HTTP_HOST} ^www\.mydomain\.com$ [NC] RewriteRule ^(.*)$ http://mydomain.com/$1 [R=301,L] RewriteRule ^search/(.*)/(.*)/(.*)/(.*) /search.php?searchfor=$1&sortby=$2&page=$3&searchterm=$4 RewriteRule ^confirmemail/(.*) /confirmemail.php?code=$1 RewriteRule ^resetpassword/(.*) /resetpassword.php?code=$1 RewriteRule ^resendconfirmation/(.*) /resendconfirmation.php?userid=$1 RewriteRule ^categories/ /categories.php RewriteRule ^([-_~*a-zA-Z0-9]+)(\/)?$ /memberprofile.php?username=$1 RewriteRule ^browse/audios/(.*)/(.*)/(.*)/(.*) /audios.php?sortby=$1&filter=$2&page=$3&title=$4 RewriteRule ^browse/categories/audios/(.*)/(.*)/(.*)/(.*) /categoryaudios.php?sortby=$1&filter=$2&page=$3&title=$4 RewriteRule ^audios/(.*)/(.*) /playaudio.php?audioid=$1&title=$2 RewriteRule ^download/audio/(.*)/(.*) /downloadaudio.php?AUDIOID=$1&title=$2 RewriteRule ^members/audios/(.*)/(.*) /memberaudios.php?pid=$1&username=$2 RewriteRule ^syndicate/audios/(.*)/(.*) /syndicateaudios.php?filter=$1&title=$2 </IfModule> Update 3 [root@smydomain ~]# ls -la /var/www/vhosts/mydoamin.com/httpdocs/cgi-bin/ total 60 drwxr-xr-x 3 apache root 4096 Sep 14 14:37 . drwxr-x--- 20 som psaserv 4096 Sep 14 14:40 .. drwxr-xr-x 2 apache root 4096 Sep 7 03:01 configs -rwxrwxrwx 1 apache root 4 Sep 14 14:37 index.php -rwxrwxrwx 1 apache apache 6520 Sep 7 03:01 uu_ini_status_audios.pl -rwxr-xr-x 1 apache root 3215 Sep 7 03:01 uu_lib_audios.pl -rwxr-xr-x 1 apache root 30249 Sep 7 03:01 uu_upload_audios.pl

• Nagios Woudn't Start, now won't Stop!

  - by Bart B

  I ran an update on a CentOS server running Nagios, after the update, Nagios failed to start. The error in the logs was: Failed to obtain lock on file /var/run/nagios.pid: Permission denied So, I checked and there was no pid file for Nagios in /var/run. I created one and gave it the following permissions: -rwxr--r-- 1 nagios nagios 6 May 31 11:58 nagios.pid Nagios then started and seems to be running normally. The only problem is, it refuses to stop now, so I can't re-start it to add new servers and services to be monitored! When I issue the command "service nagios stop", I get [FAILED], but nothing at all gets outputted to the log, and the service remains up. Any ideas on how I can get the service to stop now? I'm running the RPM version which was installed via yum from the RPMForge repositories. The server is CenotOS 5.5.

• Ubuntu + latest samba version, symlinks no longer work on share mounted in windows

  - by Roy Rico

  I just apt-getted (apt-got?) the latest software for my Ubuntu 9.10 linux box, and I noticed that samba was the included in the update. After the install, the symlinks in my home directory no longer work when mounted as a drive in my linux box. They worked literally seconds before I did the update. All my normal directories work just fine. Viewing the directory listing on the command line, all the files, dirs & links have the exact same permissions, yet this is the error I get: Location is not available L:\LinkDir is not accessible. Access is denied. I looked on the forums, and i saw this option for the smb.conf follow symlinks = yes wide symlinks = yes unix extensions = no I put those in, but they had no effect. Has anyone had this problem yet?

• Checking for orphaned snapshots - ESXi5

  - by Tim Alexander

  So we had some issues with our passive mail node over the weekend doing vmtools updates and to resolve a problem we had to revert to a snapshot and then reseed all the databases across. All in all everything seemed fine, the server works and CCR copy status is running fine. I used the "Delete All" option this morning to remove the snapshot and the process according to vCenter has completed with no errors and no "Needs Consolidation" flag. This all seems fine until I check the Datastore that holds the VM on our SAN and I can clearly see snapshots that are pretty big [see attached image]. These do not seem to be changing size and the data modified is around the time the works were started for the vmtools update. Does this possibly mean that at some stage, possibly during reversion or hard resetting of the VM, that they have become orphaned? Are there any methods to check orphaned status of snapshots? We are running ESXi5.0 Update 1 with storage provide by an EMC SAN. Enterprise plus is the license level.
