From several years my home router is Asus WL-520GC. Even manufacturer firmware is good enough for everyday users I did flash the router with DD-WRT firmware. How to do that is well explained in the dd-wrt wiki.

After upgrading my Internet connection speed I’ve noticed that I can reach maximum speed only from wired network and WiFi is maxed at 6Mbs and ping is with 5ms more than wired connection.

Ping increase looks logical since packets are encrypted and traveling over air. What puzzled me was the decrease in speed.
Initially I suspected my laptop (C-60 CPU is not most powerful one), but test results were the same from much more powerful PC.
Next step was to update all Windows drivers – unfortunately without noticeable result. As riding on update wave it was logical to upgrade also dd-wrt firmware from 13084 to latest recommended 14896 (at moment of writing this post). Main reason for that was multiple forum posts that build 13084 had problems. Unfortunately subsequent tests did not show increase in WiFi speed.
So back to reading and testing. Several forum posts suggested changing WiFi advanced setting. To cut long story short here are settings I did have success with:

Advanced Wireless Settings

DD-WRT Advanced Wireless Settings

CTS Protection Mode – > Disable
TX power -> 50
Afterburner -> Auto

In addition I did basic WiFi survey to determine how channels were used in my area and set least used one.

Here is the result:
WiFi speedtest

If you have comments or suggestions on how to improve the speed even more, please share in the comments.

Zerobin service is updated to version 0.19.
As a reminder for those wondering what is this:

ZeroBin is a minimalist, opensource online pastebin/discussion board where the server has zero knowledge of hosted data. Data is encrypted/decrypted in the browser using 256 bits AES.

Here are the updates from previous version (0.18)

  • Corrected XSS security flaw which affected IE<10. Other browsers were not affected.
  • Corrected spacing display in IE<10.

Mute Screamer uses PHPIDS to detect attacks on your WordPress site and react in a way that you choose.
If you have too many intrusions in you Mute Screamer log (v 1.0.7 at time of writing) removing them via Admin (web) interface could be time consuming.

Faster is to do that directly on the database.

Just execute this SQL command (MySQL in this example) on your WorPress database:
TRUNCATE TABLE 'PREFIX_mscr_intrusions'

NOTE: “mscr_intrusions” is default table name and PREFIX is your WordPress prefix you set on installation, please replace with correct value. if you do not have that table you can look for the name at line 53 in mute-screamer.php.

I will be glad to see clean all button in one of next versions.

Since version 2.0 of VLC a lot of changes were made in the code of this popular media player.

Something annoying was the increase of CPU usage when playing audio files. From almost 0% to 10-20%.
On powerful system this increase is almost unnoticeable, but on Intel Atom or AMD C60 you can notice the difference.

The fix is really easy.
Shutdown VLC and just erase/rename following 2 files from VLC folder (in my case C:\Program Files (x86)\VideoLAN\VLC\plugins\codec):

  • libsamplerate_plugin.dll
  • libspeex_resampler_plugin.dll

And this is all. CPU usage is back to normal.
I did not notice any problems for now.

Finally I can use again VLC on all my systems.

New Debian (Wheezy) has just been released. Here you will find how to update quickly.

This post is an update of Debian – upgrade to Squeeze.

Notice: Before you start the upgrade – upgrade your current system and backup your data

Here is the process:

1. Edit sources.list
vi /etc/apt/sources.list>
2. Replace distribution name (Squeeze) with Wheezy.

(press : and type)


Then you execute the upgrade in two easy steps.

apt-get update

apt-get dist-upgrade

Then to finalize the upgrade:

Zerobin service is updated to version 0.18 alpha.
As a reminder for those wondering what is this:

ZeroBin is a minimalist, opensource online pastebin/discussion board where the server has zero knowledge of hosted data. Data is encrypted/decrypted in the browser using 256 bits AES.

Here are the updates from previous version (0.15)

  • FIXED minor php warnings.
  • FIXED: zerobin.js reformated and properly commented.
  • FIXED: Directory structure re-organized.
  • CHANGED: URL shortening button was removed. (It was bad for privacy.)
  • ADDED: Deletion URL.
  • small refactoring.
  • improved regex checks.
  • larger server salt on installation.

  • “Burn after reading” option has been moved out of Expiration combo to a separate checkbox. Reason is: You can prevent a read-once paste to be available ad vitam eternam on the net.

Adding few DNS records from GUI is a breeze, but when you have more than one some automation will help.

Windows provides command line tools to help you with that.

But the trick is that you have to get your hands “dirty” and type some commands in bat file.

In this case I’m using dnscmd tool (from Windows Support Tools).

If you are unsure how to install it check Install Windows Support Tools tutorial from Microsoft

Here is dns.bat:

@echo off

set dnshost=localhost
set domain=

echo “We are reading records from records.txt”
for /F “tokens=1,2,3 delims=,” %%G in (records.txt) do dnscmd %dnshost% /RecordAdd %domain% %%G %%H %%I

It reads records from records.txt formatted in following way:

<hostname>,<record type>,<IP>

First record is hostname (without domain) followed by record type (A, PTR…) and last ip addres

NOTE: there is comma separating all values

How to use it:

1. Put your records in records.txt

2. type dns.bat

3. That it is… (Probably good time to validate 🙂 )

Since version 19 Mozilla Firefox comes with build in PDF viewer.

Generally it does the work and it is really useful when no another PDF reader is installed, but in some cases is not so appropriate and you might be better with external viewer.

Problem I have is that it is Java Script based and even JS is really fast on low power machines it is not as fast as “real” plugin.

In case you need to disable build in viewer do following:

  1. Open Firefox Options
  2. Go to ApplicationsFirefox default PDF viever options
  3. Find PDF in the list and change the action from Preview in Firefox to appropriate one.

That is all…

To control the daemons that are started at boot in Debian simply use following commands.


To enable a daemon:

To disable daemon:

update-rc.d <daemon> disable


NOTE: In above examples <daemon> is the name of the daemon listed in /etc/init.d/
