Posted on in Categories Howto, Linux, programming, Shell scripting, Sys admin, UNIX last updated January 19, 2009

This may come handy while writing cross-platform scripts.

If you don’t want to commit to the idiosyncrasies of a specific shell running on a particular platform, try the Squirrel Shell. The Squirrel Shell provides an advanced, object-oriented scripting language that works equally well on UNIX, Linux, Mac OS X, and Windows systems. Write a script once, and run it anywhere.

Squirrel is a high level imperative/OO programming language, designed to be a light-weight scripting language that fits in the size, memory bandwidth, and real-time requirements of applications like video games.

Mail merge is a software function describing the production of multiple documents from a single template form and a structured data source. This helps to create personalized letters and pre-addressed envelopes or mailing labels for mass mailings from a word processing document which contains fixed text, which will be the same in each output document, and variables, which act as placeholders that are replaced by text from the data source. The data source is typically a spreadsheet or a database which has a field or column matching each variable in the template. When the mail merge is run, the word processing system creates an output document for each row in the database, using the fixed text exactly as it appears in the template, but substituting the data variables in the template with the values from the matching columns.

This technique of merging data to create mailshots gave rise to the term mail merge. OpenOffice.Org has a in built software mail merge feature.

If you haven’t tried OpenOffice.org’s mail merge feature because you find it confusing or difficult to use, you are in luck. Mail Merges in OpenOffice.org and StarOffice provides a detailed description of the mail merge feature from start to finish. Among other things, it shows how you can use the mail merge to create letters, labels, and envelopes.

Nokia To Add LGPL Option For the Qt UI and Application Framework

Posted on in Categories Kde, Linux, Linux desktop, OS X, UNIX, Windows, windows vista, X server last updated January 14, 2009

Good news for all developers! QT will be available under the LGPL starting with version 4.5. The GNU Lesser General Public License (LGPL) is a free software license published by the Free Software Foundation. The LGPL places copyleft restrictions on the program itself but does not apply these restrictions to other software that merely links with the program. There are, however, certain other restrictions on this software. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications, most notably Mozilla and OpenOffice.org.

This option could increase Qt usage and adoption. You may see more cross platform commercial application on the Linux desktop. This is huge news for cross-platform developers.

Google Chrome 2.0 Early Access Version Is Here

Posted on in Categories Linux desktop, Mozilla, News, OS X, UNIX, Windows, windows vista last updated January 9, 2009

Google Chrome is a web browser developed by Google and based on the WebKit layout engine and application framework. On January 08, 2009 Google introduced a new release channels system, and now there are three distinct release channels – Stable channel, Beta channel, and Developer preview channel.

Google has released Chrome 1.0 on Dec – 2008, and now the company is all set to release version 2.0 (pre – beta version) of its web browser. From the release notes:

New version of WebKit. WebKit is the open source code Google Chrome uses to render web pages (HTML and CSS). 1.0.154.36 used basically the same version of WebKit as Safari 3.1, but the WebKit team has made a lot of improvements since that was released. 156.1 uses WebKit version 528.8 or, more precisely, revision 39410 from the WebKit source tree. In addition to fixing bugs and enabling features like full-page zoom and autoscroll, the new version also enables some nifty CSS features.

New network code. Google Chrome now has its own implementation of the HTTP network protocol (we were using the WinHTTP library on Windows, but need common code for Mac and Linux). We fixed a few bugs in HTTP authentication and made Google Chrome more compatible with servers that reply with invalid HTTP responses. We need feedback on anything that’s currently broken, particularly with proxy servers, secure (https) sites, and sites that require log in.

Look like the Mac and Linux versions of Chrome are getting closer. Are you going to switch to Google Chrome under Linux?

Leap Second To Be Added End Of 2008 And Its Impact On Clustered Computers / Network

Posted on in Categories Hardware, High performance computing, Linux, News, Sys admin, Tips, UNIX, Windows server last updated December 31, 2008

Get ready for a minute with 61 seconds. Scientists are delaying the start of 2009 by the first ‘leap second’ a timing tweak meant to make up for changes in the Earth’s rotation.

The aged Earth is slowing down in its daily rotation, at least in the current epoch. So a leap second is added (a one-second adjustment added) to our time. This year will be exactly one second longer.

Precise time measurements are needed for high-speed communications systems among other modern technologies such as clusters, GPS, networks. You need to make sure that you are running updated version of ntpd that support leap second for UNIX and Windows computers.
