The SOA Workshop day

Today was “THE Workshop Day” for WSO2 folks, an event organized by WSO2 with an intention to make an awareness of SOA building blocks. I was (proudly 🙂 ) among the audience as a WSO2 crew member, listening to all the tech talks of my collogues. It was a great session we had today, starting from Paul’s introduction to SOA and until Asanka’s talk about enterprise SOA pattern’s. The whole set of talks took me back in time where I was reading about SOA concepts for my bachelor’s thesis. If I had experienced this workshop then, life would have been much easier :P.

Guys,.. cheers !! for a job well done 🙂


Convert from HTML to XML with HTML Tidy

For few days I was involved with WSO2 Mashup Server 2.0 release documentation, giving a hand to the mashup team. Documentation is a painful task, but when comes to open source what matters mostly is documentation :D.
Last night I had to convert a bunch of html files (some Java Api Docs) to xml in-order to port into maven site. Formatting 30+ html files to xml !@#$%^&*@% :D. So I was googleing for a tool to automate the task. With few clicks here and there I found a nice article in Big Blue‘s developer works site, a tool called “Tidy“. When I tried to download and use I figure out that you can straight away apt-get the package and use. So,

sudo apt-get install tidy

and your box is now equiped with the tool, and can be accessed via the shell.

tidy -asxhtml -numeric  index.xml

but who wants to convert file by file when you have such a nice tool, so I spent few minutes in writing a tiny shell script to get the job done, the snippet is,

for file in $(find $1 -type f -iname '*.html'); do
	myf=`echo $file | sed 's/html/xml/g'`
	tidy -asxhtml -numeric  $myf

All looked good, worked fine. However in my Api Docs I had, had few special tags, custom to our Mashup Apis (<imconfig>, <yahoo>, <mail:config>). Tidy gave error for these files since the tags are not recognized.

In such a case you can train Tidy for new tags, by adding few lines to the tidy configuration file. (/etc/tidy.config – You can also give your own config file at the prompt)

new-pre-tags: imconfig, yahoo, msn, aim, icq, jabber, username, password

There are whole bunch of tweeks you can do with tidy, [1], [2] and [3] are some useful links that you can read up when using the tool.

Lesson learnt the hard way

Terminator was running in four segments, top left was a maven build, top right was a svn update, in one of other two an apt-get was running and I was playing on the smaller one left in bottom right. My notebook was running on battery power and I forgot to plug it in to AC, before the box got hibernate. Once I reboot it with AC power my X-Server was gone !! I couldn’t see the log-in screen and it just left me with the console in full screen.

I am not a linux guru, but i tried few commands, “startx / dkpg -reconfigure / nvidia-config / etc”. I had to run to our sys admin since he is considered the guru :D. with few commands at flash speed he got the x-server running again. but it was all broken here and there. couldn’t hear sound, installed apps were not working and above all when I reboot, I had to type “startx” each time to see the display (Which was a pain and made me itchy :P). Chamith’s idea was even if he could get the x-server running in normal mode, some errors that am getting wont be able to fix. so the best option to make all smooth is to re install the OS and he said “No probs ne machan (sinhala way of saying dude / bro 😉 ), ur home is in a different partition right ? so its a matter of ten minutes to restore the root in the other partition.” – OH CRAP NOOO my /home was also in the same partition and I only had one single big partition. 😦

SO yeah I had no other option left, I had to back up 20GB of my /home dir and re-install ubuntu 9.04. (Coping 20GB from here and there is a crappy and a messy job) I was struggling with the fix till today morning and finally got everything smooth again.

SO the lesson from all of this is. keep your /home mounted in a different partition. I learnt the lesson, the hard way.

SL vs NZ T20 | My 1st time among international cricket audience

Its like this, I am not a huge cricket fan, the matches make me bored along the game. One guy balls, another guy slowly hits and 8 people try to send him to bench (but should mention, when the batsmen hits hard or when others send him to bench its always fun 😀 ). Being in Sri Lanka one thing you inherit is the cricket fever, from your grand dad to siblings, they all watch (or maybe play) cricket. The Wills world cup (1996), I just rem from here and there, (I was in grade 5 😀 good times) is one nice memory I have, Sri Lanka winning the big cup and we all were staring at the TV with great joy.

Anyways with all that background story, yesterday I happened to be there at R. Premadasa international cricket stadium to watch the Sri Lanka vs New Zealand T20 match. Folks at work made plans to watch the match for weeks and finally 12 turned up. (This time the numbers were low coz there was a rumor that SL lost the SL vs Pakistan match coz they were there that day) however I took a ticket (Dumindu Threatened me to buy :D) and was there few minutes before the game started.

Dilshan on fire :D

New Zealand batted 1st and the game became fun, with all the cheering, shouting and screaming. The foreigners were good they played 141 for 8 wickets and it was the time for the home players. I was amused, I was not bored in fact I enjoyed it so much and was waiting till our innings start.

The SL inning started after about half an hour with some drops of rain, but it was all good. The fans were shouting.. “Go SRI LANKA”, “Common SANGA / SANA / DILSHAN” and I was among them too. The 1st half of the innings was great, Dilshan played well with a 50 in 23 balls lifting the SL run rate. My hopes were for Jayasuriya coz he was my hero since 96, but he was out with 1 run and it was disappointing. With Sri Lanka’s 3rd wicket (Sangakara) the batsmen kept falling. and there was no one to carry on Dilshan’s run rate. but until the last over we had the chance to win, it was 9 runs with 7 balls, then 8 with 5 and finally 3 with 1. So we lost. 😦

I saw the faces of people around me, all their happy faces are turned dark, and it was sad indeed. But well for me I was happy, (Not for we lost) I enjoyed the match, the time I spent, even the defeat, we gave a good fight. So yeah it was one great experience for a newbie cricket fan.
