Yipee! Got a new job; got a new job! I’ll be in touch with different set of articles,… how could it be like being a JIRA administrator. During last few months I had nothing special to blog. I don’t do politics, rarely gossip, and I’m a tech-blogger. Filed under: blogging, lifestyle, tech Tagged: ආගිය කතා, [...]
Today, I encountered a problem when the edits I made to ‘/etc/hosts’ file on a Linux box didn’t work as expected. In the /etc/hosts file I added the following line, 192.168.50.2 shaakunthala.com And to test, issued the following command, $ ping shaakunthala.com And the result was, PING shaakunthala.com (184.168.221.17) 56(84) bytes of data. That’s not the IP address I wanted ...
As you may have already experienced, Javascript on Chrome works faster than on Firefox. But today I’ve experienced the other way when using them on a virtual machine. It was a virtual machine (VirtualBox) running Windows XP and on that Firefox seemed to be working faster and smootly than Chrome. Especially when browsing sites that have rich Javascript content Chrome ...
It’s cool to see that Ubuntu 10.10 Maverick Meerkat is scheduled to release on 2010.10.10. In every 6 months a new Ubuntu is born. Usually it’s April and October. This time it’s three tens in a row. Yes, it’s 10.10 and I can’t even wait for the experience! Tomorrow I’ll be downloading the RC from SchoolNet. Till ...
As per the documentation provided in the following page, once you query ALL_TAB_COLUMNS, database views and view columns are also included. There’s nowhere specified whether the table is actually a table or a view. http://docs.oracle.com/cd/B19306_01/server.102/b14237/statviews_2094.htm However, with the following SQL it’s easy to exclude views and retrieve table columns only. select table_name, column_name, data_type, data_length, ...
Do you use Two Factor Authentication with your mobile phone? Do you use your phone as a password recovery option? In case if you are wondering what the hell is two factor authentication, let me simplify it like this. Have you coupled your Gmail/ Facebook/ etc. account with your mobile phone in a way that you receive a ‘code’ that ...

This could be a great alternative if you have used TrueCrypt encrypted volumes. I’ve been a TrueCrypt lover for a long time, even after it was allegedly killed. But now I’m starting to think that it’s not a good option for long term safekeeping of my memories. At time point in a future release of Linux if dependencies for TrueCrypt ...
So I’ve been reading more on cryptsetup man page and found this interesting excerpt: If the header of a LUKS volume gets damaged, all data is permanently lost unless you have a header-backup. If a key-slot is damaged, it can only be restored from a header-backup or if another active key-slot with known passphrase is undamaged. Damaging the LUKS header ...
Every time Ubuntu releases a LTS version that’s the time I spend time on a version upgrade. Spending few hours on upgrading and some underhood stuff once every six months is not for me, so I decided to stick to LTS. So, the normal routine would be running ‘sudo do-release-upgrade’. For some reason it doesn’t work for me anymore with ...
If you are into software development, you may have wanted to drop all tables of an Oracle database schema in a single shot. How do you do it? Here’s how I do it with a simple PL/SQL procedure. begin for i in (select * from tabs) loop execute immediate ('drop table ' || i.table_name || ' cascade constraints'); end loop; ...
So I’ve been playing around with one of those recent Facebook features. That’s called “Did You Know?” aka Fun Facts. I kept tapping on “New Question” most of the time because I wasn’t sure what to do with the most. You really need to think more than twice before posting anything on social media these days. Some questions like “A ...
Once installed their app, Facebook thinks they own our mobile devices. At first, there was the peaceful all-purpose Facebook app. And some time later they separated messaging into another app, creating the Messenger. Initially it was at user’s discretion to use Messenger or Facebook app for messaging. Initially it looked polite but lately everyone was gradually forced to install Messenger. Another ...
Yesterday I wrote about How to create an encrypted LUKS disk image. Today I wanted to experiment more with it. I wanted to try resizing a LUKS volume, and after one failed attempt I found a way. If you still have the disk image of yesterday’s example, just follow me. Safety first! Unmount, luksClose and then backup your image file. ...
These days I’m working on a JIRA project which may require working with XML backups and project import tool. The JIRA instance I’m currently working on has over one million issues in thousands of projects (including defunct) – that collectively make the XML backup gigantic. Have you ever come across the situation where you want to delete some of the ...
I have noticed that Google blogger blogs are not accessible with SLTnet if they are configured to use custom domain. For example, http://blog.shaakunthala.com is not accessible with SLTnet at the moment. This is not due to a misconfiguration of DNS, but a technical failure of SLTnet. By default, http://ghs.google.com:80 should provide a ‘Not Found’ page. But with SLTnet connections, you’ll ...
Today I’ve been importing an Oracle database to a test server to copy a JIRA instance. I’m doing this after many years, because, at work what I would normally do is talking to the DBAs. However, in this case, this is a personal database server I maintain for testing purposes, so I’m on my own. I hit a snag when ...
