To resolve this on a debian host just remove the entries in

/etc/udev/rules.d/70_persistent-net.rules


Actually this line sends a keep-alive packet to the server every 5 seconds. You can change the interval as you like, but for me it works best with 5 seconds.

Alternatively you can also use the parameter when connecting to the remote host. The command looks like this:

ssh -o ServerAliveInterval=10


seems like facebook got hacked

I guess that it has something to do with the latest phishing attacks facebook is facing… or they are just trying out to provide a new service.

Update: Just found a set on Flickr with hacked Twitter accounts

Slashdot, Reddit, delicious, Furl, Newsvine and Digg are direct an enormous amount of user in a short time to very interesting articles. To prevent your server to fail I suggest you to check these things.

Check the mpm_prefork mod

In this module you should focus on the following three values:

• StartServers: Defines how many servers should be created at startup
• MaxClients: Number of servers allowed tobe started
• MaxRequestPerChild: Defines how many requests a server should handle before beeing killed.

Suggestion: Put your StartServers around 32 and keep the MaxClients high. When tweaking here don’t forget to check how many connections your database can handle, you might have to change things there too.

Disable KeepAlive

… make the math. Apache is keeping the connection alive by default for about 15 sec. It supports a max of 256 connections at a time. If you have 800 people requesting your site at a time Apache will serve the max amount of supported connections (256) and let the other 544 people wait. A workaround would be to decrease the KeepAlive to a lower value.

Focus on the PHP settings

You should check if PHP is running in CGI mode, because if that is the case it is damn slow. It should be configured to run as a module (mod-php5), thats the fastest way you can have it.

Benchmarking

To benchmark your site just checkout ab. It normally comes with the default Apache installation.
Run ab -n 10000 -c 100 http://yourhost/index.php

This makes 10k requests split over 100 smiultaneous connections. The results are somehow self speaking.

Installation is easy:

1. Copy the contents of the file to your wp-content/plugins folder
2. Enable the plugin in the admin menu
3. chmod 777 the file in wp-content/plugins/phpids/log.txt

NOTE: check for new Filter releases at phpids to update the filter.

I tried it out this morning and first impression was, “ok now you can see the street”. But if you click on the arrows you can even move along the street and with the other arrows you even can turn around!!

This is awesome. The service is at the moment only available in the US. If you are outside the us just add &gl=us at the end of your URL and you can enjoy this service!

For Example this link shows wandering on the Time Square in NY. You definitely have to check this out!!

• 02.05.2007 Skype for Linux 1.4.0.58
  • Major user interface overhaul.
  • Audio quality has been improved.
  • Calls are now contained in a separate window.
  • Chat history can be loaded in time-specific increments (rather than ‘recent’ and the very slow, ‘all’)
  • File transfers are now grouped in a common window, and similar transfers are also grouped together.
  • Event history now contains chats and other events in addition to calls.
  • Sound files are now located in /usr/share/skype/sounds. This directory will be configurable later, however the sound files from the original Skype 1.4 package should be placed into this directory for now.
  • The top menu bar has been removed. You can access the Main Menu by clicking on the ‘cog wheel’ down the bottom left of the client, or by right-clicking on the system tray icon.
  • Add/Search users can be accessed by clicking on the Green + button in the bottom-left corner.

But there is still no way to make video calls :/ But it is nice how they handled the thing with the menu. I also didn’t find a way yet to make this with a plugin. In the beginning I used Festoon on windows, but this is not available for Linux.

I just found another glinch. In my taskbar they changed the program logo to vector style but they still missed the chat icon.

If you want to get the new version of Skype head over here.
