Samsung Galaxy S2 tip

It seems that Samsung is using by default the fast dormancy, a new technology which tries to save your battery life by turning your phone completely connection less if no activity is detected. This is cool, right? Not really, since in order for this to work, network provider has to support it as well, which makes the completely opposite effect, by draining the phone battery and still make phone disconnected when idle (e.g. no SMSes received).

To disable this (my strong suggestion), do the following:
*#*#9900#*#* and then choose
disable fast dormancy
and then
Exit
.

I have tested this already for 1 month, and it works pretty fine, and battery life is extended definitely by some 20%-30%.

Summary:
- it prolongs/extends the battery life
- it solves the issue of phone being completely disconnected at times

Timeline on Latex

One of nicer looking timeline graphs for Latex is by using the chronology package This is the example: \usepackage{chronology} ... \begin{chronology}[5]{1983}{2010}{3ex}{\textwidth} \event{1984}{one} \event[1985]{1986}{two} \event{\decimaldate{25}{12}{2001}}{three} \end{chronology} source .

Exporting Skype Chat/Skype Contacts to csv file using the shell script and sqlite3 (usually already installed on mac)

Edit: a very first draft version of Skype Exporter have been made and released. https://github.com/renesto/SkypeExportSwift/releases check it, and report any issues to renesto-at-gmail.com I heard there are not so many nice ways to get the chat history from skype, so I came across a page of one guy who shows a way to open the sql chat history database and delete all conversations. I thought to make something more from that idea (as delete chat history is now one of the options in skype) Create a file exportFromSkype.sh place either this text: sqlite3 -batch "$HOME/Library/Application Support/Skype/$1/main.db" < <EOF .mode csv .output $2.csv select * from Messages where dialog_partner = '$2'; .output stdout .exit EOF now make the script executable by running chmod +x exportFromSkype.sh now, when you want to export some chat history from certain person, you can do it by: sh exportFromSkype.sh your_skype_name your_friends_skype_name and i

trim() not supported by IE7 and IE8

Funny fact, trim function is not supported by IE7 and IE8. Ok, it is supported, but through jQuery trim function. So, when you have something like this: jQuery(...).attr().trim() , this trim() function stops having any relation to jQuery, as the attr() would return String type, which method would be then trim(). Since IE7 and IE8 do not support trim() method within String type, you should use instead jQuery.trim(jQuery(...).attr()) or if you don't wanna use jQuery (whyyyy?), you can simply implement the trim function youself. if(typeof String.prototype.trim !== 'function') { String.prototype.trim = function() { return this.replace(/^\s+|\s+$/g, ''); } } http://www.blogger.com/img/blank.gif source 1 source 2
