Tool of the day: Thinkfree

2006-10-06T23:00:00.000-07:00

ThinkFree is an online office product. Though not the best one but a better one than Microsoft's Live. It is one of the PCWorld's Top 100 best products of 2005.I've used ONLY the word document so far. The features that I like and used are..

1. Converting to pdf
Works fine and looks nice. Unfortunately cannot post it to blogs.
2. Post to blog
You can directly post the document you created to blog.s Works fine with blogspot and wordpress blogs.
3. Free and 1GB storage
4. Cross platform

The features that I don't like so far are

1. The PowerEdit is slow as it uses java
2. QuickEdit is very buggy and for some reason removes the '+' character always from the doc

Tip of the day: DOS & Windows Explorer

2006-09-21T14:28:00.000-07:00

You can enter "explorer /e,." (explorer, space, slash, e, comma, period) at the prompt to open Windows Explorer in the folder you're working with in DOS. Handy when you sometimes want to work Windows Explorer GUI while working in DOS command mode..

Topic of the Day: Virtual India

2006-01-21T02:50:00.000-08:00

Apologize. It is out of the topic for this blog but I found that I should share this.

Microsoft is never shy to copy & yet bold to call it their research. In this case they copied Google Earth technology,extended it to be multi-lingual and call it Microsoft Virtual Earth technology. Virtual India is built out of this (copied??) technology with Govt of India. The map is now online & currently supports street level searches for Bangalore city alone. Still in proto-typing phase. Yeah copying without patent violation takes time.

Tip of the Day: New feature of netstat command in XP

2006-01-21T02:07:00.000-08:00

If you have never heard or used netstat command before see here. There is a cool new option to show name of the process associated with the connection or listening port. Here is how to use..

C:>netstat -b

This option will display the executable. If the executable is an host then the components associated with connection or port is displayed. A cool feature of trouble-shooting network related in distributed systems. I previously had to use a seperate application for this purpose.

Tool of the Day: AVG AntiVirus

2006-01-15T01:11:00.000-08:00

A free anti-virus software.VB(Virus Bulletin) has given it 100%, ICSA certified & so thought it should be good. My pc-cilin has expired on my stand-alone home PC and was looking for a good GNU anti-virus software & found this one. My guess was right. It is a good, simple & effective tool. The installation was smooth. The updates & scanning could be done only once during a day in the free edition but could be scheduled. I used it for a week and all of the updates & checks were successful. I tested with couple of viruses & worms (old though) and AVG was quick to catch them :-) Would definetly recommend.

Read & follow the license agreement. AVG free edition is allowed ONLY for stand-alone home PC & is not for commericial or office use.

Tool of the Day: TestDisk (Partition Recovery)

2005-12-26T15:03:00.000-08:00

This is an excellent utility to recover lost paritions. It is an OpenSource software and is licensed under the GNU Public License. I strongly recommend the newbies to run this utility in log/debug mode and send the output to experts or forum for recovery instructions.

Tip of the Day: Improve your screen readability on XP

2005-12-26T02:25:00.000-08:00

Have you ever wondered why you prefer to print and read from papers rather than screen directly?The answer is that the fonts appearing on the screen are not sharp & clear as the printed material. Microsoft has attempted to resolve this pain of customers through ClearType. I think they did really well. See it yourself to believe it. The improvement is very impressive in LCD. I personally don't see much in the CRT. You can enable ClearType on XP using the following web interface.

http://www.microsoft.com/typography/cleartype/tuner/Step1.aspx

Note:
1. Use IE instead of firefox as this enabling is based on ActiveX control.
2. After this, increase your screen resolution and see that now you'll be comfortable with larger resolutions. I use (1400 x 1050) than (1280 x 1024) when ClearType is enabled. Saves lot of scrolling & tabbing.

Topic of the Day: Why functions

2005-12-06T22:17:00.000-08:00

Functions are the basic building blocks of programming either be procedural or object oriented.
We all know to write functions possibly in every language we learn (How?) C,C++,Java,C#,PL/SQL,JavaScript,VBScript,Python etc., There are several different opinions/reasons/views on why use functions. A common notion among most developers are that functions improves reusability (technically speaking it is ability to use in multiple programs) but it is not just that.My introspective view reveals the following (for Why?)

Readability: Simplifies my program by substituting a complex set of commands (instructions or statements) with English words (call instruction - name of function). Eg: Sum(100,200)
Reusability: Eliminates repetitive code (redundancy) within the program. Program becomes smaller.
Testability: Simplifies unit testing.
Stability: Well unit tested functions leads to a stable program.
Extensibility: Easier to add new features as the program is now smaller,readable,testable & stable. This apart from the fact whether the new extension uses the existing functions or not.
Maintainability: Stable & extensible programs are easier to maintain.
Productivity: Easier maintainable programs increases our (Developer's) productivity.
Technicality: Information hiding or better execution (say recursive). This is more of When? to write functions.

So next time you write a bunch of statements (code) think whether writing them as a function solves even any one of the above top 3 reasons & if so then write them as functions.

May be I'll write samples to substantiate this introspection of mine over this week end.

Tool of the Day: PrintKey2000

2005-12-05T20:28:00.000-08:00

A good tool for taking screen shots either entire screen or portion of it. It also allows to save in several different file formats. There are options to edit the picture for size,color,rotation etc., which are very cool of a freeware program. Note: Only PrintKey2000 is free, newer versions are NOT.

Tip of the Day: DOS can also be colorful

2005-12-05T00:45:00.000-08:00

Yeah you read it right. For Windows XP & 2000 users, the DOS windows foreground & background colors can be changed. Please note the following special behavoir: When you specify only one color it is meant for foreground. When you specify 2 colors, first is for background & second is for foreground.

Example: Changing the foreground color to Light Aqua (B). This is my favourite
c:>color B

Example:Changing the background color to Red (4) and background color to Light Aqua (B).
C:>color 4B

Work with some color in life...

Topic of the Day: Hidden powers of copy command

2005-11-22T23:06:00.000-08:00

Though we everyone knows the purpose of copy command there is one more function in it which we overlook. It is the power to append files. This function comes handy in several situations specifically for ad-hoc purposes. Here is how..

Scenario: Append content of file 2 to file 1.
Example: Copy file1+file2
Scenario: Merge two files to form a new file
Example: Copy file1+file2 file3

Note: This above solution could be applied to any files (text,doc,xml etc.,)

Tip of the Day: Display DOS names of file/directories

2005-11-22T20:19:00.000-08:00

Current windows OS versions allow long names for files & directories. Batch file operations which are based on DOS do need 8.3 format file or directory names to work with. To retrieve the short name (aka DOS name)of such files or directories use the following dir command.

C:>DIR /X

Displays the name of the file or directories in 8.3 format.

Tool of the Day: Firefox

2005-11-22T19:16:00.000-08:00

A tool that I use everyday in my life. Here is why with some hows

Free.
Yes its right you don't need to pay for such an safe,secure & efficient browsing tool.
Safe & Secure
When I use the "e" icon on my desktop I get to have the malicious spware & adware from around the world.Some don't go away no matter what you do. Even latest & popular MS AntiSpyware Beta or Spybot can't. Firefox is the only solution for safe & secure browsing.I've been using this tool without even a single spyware infection on my desktop for the past 1-1.5 years.I spearhead this tool's use even among non-developer community.
Usability - Efficient browsing
1. Tabbed Browsing
  View more than one web page in a single window with this time saving feature.Behavior customizable via Tools->Options->Advanced menu.
2. Autocompletion
  Stores the information entered on web-forms & search bar to make fillin g out forms & searching faster.Customizable via Tools->Privacy menu.
3. Password Manager
  Stores the login information so that you don't need to re-enter.You can set master password & also view the saved password.Use this feature only on your desktop.For "e" we need third party tools for this purpose. Its free here.
4. Customizable Search
  You can add search engines to customize the search toolbar behavior. Very useful & time-saving feature. I use wikipedia & encarta dictionary via this.
5. Text Zooming
  To make pages with small text easier to read.Use Ctrl++,Ctrl--
6. Bookmarks
  A powerful feature to add bookmarks to the toolbar. You can group them in a folder. Later you can open all bookmarked site under a folder in tab. Very efficient browsing.
Hassle-Free Downloading
Files you download are saved automatically to the specified directory.Downloads could be paused & continued later.
For Web-Monkey's
Comes with a standard set of developer tools including a powerful JavaScript and CSS error/warning console, and an optional Document Inspector that gives detailed insight about your pages.

Tool of the Day: TextPad

2005-11-21T14:57:00.000-08:00

A tool that I use everyday in my life. Here is why:

Free
Yeah we everyone like this.
Cross-platform:
You can create files for use in PC/UNIX. Comes very handy when you are not dexterous in Unix editing tools.It says it supports Mac but i never used this OS so can't comment on it.
Block Select Mode
You can select portions of the data in the file that you need.
Find-in-files
A very handy feature.Search for a string in files under a particular directory. You can limit the search to particular file type & also extend the search within sub-folders.
Regular/Replacement Expression Support:
A programmer's haven. You can use limited but still extensive regular expressions in your search & replace operations. Combined with Find-in-files this is the most powerful developer's util. A very handy tool for engineers dealing with ad-hoc formatting of data in files.
Use as editor for C/C++/Java
Comes default with document classes & works with compilers of C/C++/Java. A very handy tool for beginners to focus more on learning these languages & its associated concept and avoids getting distracted with learning any new IDE at the same time. I consider this as a Big plus. Like many IDE it also supports workspace. Its worth mentioning the support for HTML too.
Multiple Documents
I consider this as an usability. Work with multiple documents in a single window with each file opened in a tab. Supports file comparisons too.
Performance
The program is very stable & has better performance than conventional editors

Note: This program is accessible via the right-click context menu of a file.

Tip of the Day: Improve the power of Window's Explorer Right Click Context Menu

2005-11-21T14:22:00.000-08:00

Open Command Prompt in Directory

Would'nt it be efficient to open command prompt on right click of a folder?? It's a time saver when I need to run scripts under a particular directory.Here is how:

Windows GUI method (Easy)* Open up windows explorer * Tools -> Folder Options. * File Types Tab * Select the Folder file type * Click Advanced * Click New * For the Action type what ever you want the context menu to display, I used Command Prompt. * For the Application used to perform the action use c:\windows\system32\cmd.exe (note on win2k you will want to specify the winnt directory instead of the windows directory)
Manual method(Caution: This requires editing your registry. If you are not familiar with registry editing, this isn't for you... so use the Windows GUI method above) 1. Open regedit 2. Navigate to HKEY_LOCAL_MACHINE/Software/Classes/Folder/Shell 3. Create a new key called Command Prompt 4. Your default value should be Command Prompt Here 5. Create a new key called Command under the Command Prompt key 6. Your default value should be cmd.exe /k pushd %L

You can use any of these above methods to customize the windows right click context menu associated with folder or file types.
