Chrome of your dream

Each of us has your-own favorite browser, that we're using in our regular life. But sometimes we just need a good solution for a portable browser that we can run from our USB flash-drive (aka disk-on-key). Today I'll tell how to make a portable build of Chrome.

1. We need to download the last available build ( of Chromium. You can find it here:;O=D

2. Create a new folder «Chrome»

3. Unzip to this folder. The path to chrome.exe must be something like «..\Chrome\chrome-win32»

As I told above, we want to build a portable build of browser that could work from USB-drive at any PC. Because Windows doesn't support relative path in shortcuts (LNK-files) we have to create a separate cmd-file with startup options as command line parameters.

Create a task in Windows XP/7 Task Scheduler using batch file

In my current job we needed to automatize some processes by using Windows Task Scheduler; I wrote a batch file, which you may find useful,
especially when you don't have direct/remote access to user's desktop.

The main problem of implementation this task was Windows Vista/7 with its UAC, I had to use powershell to get Admin privileges by popping a window prompt to user directly to accept rather than have the user type the password manually upon the request.

SQL - Update Select (Update a Table Based on Values in another Table)

A simple and quick snippet of SQL to update table values based on the values stored in another table — in other words, UPDATE SELECT. This code has only been tested in MySQL, similar code may be used in MSSQL or other database engines which I will try and add later.


SET    Dest.Address1 = Src.Address1,
       Dest.Address2 = Src.Address2
FROM   SourceTableName Src
JOIN   DestinationTableName Dest ON Dest.PersonID = Src.PersonID


UPDATE DestinationTableName Dest, SourceTableName Src
SET    Dest.Address1 = Src.Address1,
       Dest.Address2 = Src.Address2
WHERE  Dest.PersonID = Src.PersonID

Confluence+Tomcat+HTTPD(handling HTTPS traffic, with Tomcat backstage) - The easiest way to install Confluence with Tomcat and Httpd!

Confluence is the best Enterprise wiki IMHO.
So that's how you can install and run it -


# cp jdk-6u18-linux-x64.bin /srv/
# cd /srv
# sh jdk-6u18-linux-x64.bin
# ln -s jdk1.6.0_18 jdk

# updatedb;locate javac |grep bin
Here /srv/jdk is the actual JAVA_HOME for your machine. Note this as you will need it to run the future commands.

alternatives --install /usr/bin/java java /srv/jdk1.6.0_18/bin/java 100
alternatives --install /usr/bin/jar jar /srv/jdk1.6.0_18/bin/jar 100
alternatives --install /usr/bin/javac javac /srv/jdk1.6.0_18/bin/bin/javac 100

Simple example how-to extend JavaScript built-in methods

Let say you want to replace all spaces in string by dashes,
of course you can implement distinct function that does it:

 function ReplaceByDashes(string){
    return string.replace(/\s/g,'-');

 // run it
 var string = "Hello my beautiful world!";

However, we can add our custom method to string object that already built-in in JavaScript:

  if(typeof String.prototype.rbd==='undefined'){ // we have to check if someone hasn't added it already
     String.prototype.rbd = function(){
        return this.replace(/\s/g,'-');

 // run it

 var string = "Hello my beautiful world!";

Some useful example, capitalize first letter of string

String.prototype.ucFirst = function () {
  return (this.substr(0,1).toUpperCase() + this.substr(1,this.length));
