PHP Bijoy to Unicode Converter

Habib Ullah Bahar — Sun, 11 Mar 2012 09:46:59 +0000

In our latest project at PROGmaatic, we needed a converter to convert lots of information written in Bangla. Unfortunately everything was in Bijoy (SutonnyMJ) font. But our requirement was Unicode formatted data and language preference was PHP.

I thought, no big deal. There should have been lots of converters available, and most of them might be in PHP. After hours of searching (Yes I don’t like coding when I can find something free ).

Well, I haven’t found a single script which would do what I needed. Two of the following did help me to understand how to develop the converter:

www.repulsivecoder.com/2009/06/04/bijoy-to-unicode-converter/ [Oops! javascript only]
mynul.com/bangla/ [Mr. Mynul was kind enough to send me the source code. Unfortunately it didn't work for me when I included it in my project. Probably because of encoding dependency. Also I didn't like the mapping. But it encouraged me!]

So finally I end up coding one myself. Fork it from my Github account.

In the coding process I have learnt two valuable lessons

1. javascript string method ‘substring‘ is not equivalent to PHP’s string function ‘substr‘ [I spent only 5 hours for this mistake!!!]

2. Nothing is better than step-by-step Debugging!

Future modifications:

1. Make mbstring independent. (I actually figured out the way, but right now I don’t need it since I have mbstring support )

2. Make memory efficient.

Check the code and let me know if you find a better way, find a bug or need some modification. I will be happy to make the changes and give you the credit

How to verify an ISO image in linux before burning

Habib Ullah Bahar — Sat, 17 May 2008 10:24:19 +0000

There is no nice or 100% effective fast way to verify an ISO image of any OS [normally *INX based OS] without installing. But there are several ways one can test the ISO image. If the test(s) are successful, there is a high (to me which is almost 100% ) probability, that the ISO is perfect to be burned in a CD or DVD which one is desirable.

After downlaoding an ISO from any source, you must validate the SH1SUM or MD5SUM which one is required in your case to verify the security and integrity of your ISO.
You can manually mount the ISO image to check its content when you are in Linux using the code
```
su -c 'mount -o loop -t iso9660  
```
You can use VMware Player to boot your ISO image, even you can install it as a virtual OS in Linux. With this free software, you can not only verify the image but you can also test the installation without changing your current installation of Linux. Download it from here.

Fedora 9 (Sulphur) is on earth…grab it!

Habib Ullah Bahar — Thu, 15 May 2008 03:49:02 +0000

So after a long time, Fedora 9 (Sulphur) has been released. The version includes some must need features.

Here is the list..

This release features GNOME 2.22. GNOME now includes a webcam photo and video creation utility called Cheese, improved network filesystem support, a new international clock applet, Google Calendar support and custom email labels in Evolution, a new Remote Desktop Viewer, improved accessibility features, and PolicyKit integration.
KDE 4.0.3 is available with more upgraded features and overall its more stable.
NetworkManager 0.7 provides improved mobile broadband support, including GSM and CDMA devices, and now supports multiple devices and ad-hoc networking for sharing connections. To me its the best feature of Fedora9.
The Fedora installer, Anaconda, now supports partition resizing for ext2/3, NTFS filesystems, creating and installing to encrypted file systems, improved Rescue Mode with FirstAidKit, independent locations for the second stage installer and the software packages.
Live USB images now support persistence, so your data and setting changes will be preserved even after rebooting.
PackageKit, a new set of graphical and console tools, with a framework for cross-distribution software management, has replaced Pirut in this release of Fedora. The PackageKit graphical updater is available instead of Pup. Behind PackageKit, the performance of yum has been significantly improved.
Ext4, the next version of the mature and stable ext3 filesystem is available as a option in this release. Ext4 features better performance, higher storage capacity and several other new features.
This release of Fedora uses Upstart, an event-based replacement for the /sbin/init daemon.
Firefox 3 brings a number of major improvements including a native look and feel, desktop integration, the new Places replacement for bookmarks, and a re-worked address bar.
The completely free and open source Java environment OpenJDK 6 is installed by default.
OpenOffice.org 2.4, with many new features, is available as part of Fedora 9.
Fedora now includes Perl 5.10.0, which features a smaller memory footprint and other improvements.
Fedora now includes TeXLive to replace the older, unmaintained TeX distribution.
Fedora 9 features a 2.6.25 based kernel.
And definitely Fedora 9 is much more stable than Fedora 8.
