The scenario is I want to install Apache (hereafter also known as httpd) on a basic plain-installed Red Hat Enterprise Linux 5.3 (hereafter known as RHEL 5.3). I thought it was quite straight forward but somehow it didn’t. I’m using RHEL 5.3, [root@m020600 ~]# uname -a && cat /etc/redhat-release Linux m020600 2.6.18-128.el5 #1 SMP Wed Dec 17 11:42:39 [...]
Colin Charles: Tracking government spending with regards to economic stimulus funds

Posted: May 6th, 2009, 5:39pm BST

The good news - the website to track economic stimulus funds in Malaysia is now ready. Check out: Rangsangan Ekonomi Malaysia.

Even better news, they used an open source software solution (Joomla!) to make that website happen. So mad props go out to them.

Only thing that irks me? Its all in Bahasa Malaysia, with no translation in English.

Colin Charles: Barry Abrahamson, talks about Wordpress.com technicals

Posted: May 6th, 2009, 11:03am BST

Tags: [edit]

While at the MySQL Conference, I caught up with Barry Abrahamson, the systems wrangler/de-facto DBA behind Wordpress.com (and all other Automattic properties). Watch the video.

You probably already know that Wordpress itself is built on top of MySQL. And despite everything you might have heard about our (MySQL/Sun’s) new founders, Wordpress is MySQL today, and for the foreseeable future. Anyway, I digress.

Wordpress.com has about 70 million tables, and tens of thousands of blogs. Large amount of tables, serve for easy sharding - after all, its based on Wordpress MU, which creates a table for each blog (read does it scale?).

Wordpress.com has a few terabytes of data in MySQL, with over 350 instances. They’re all powered by Debian servers, with MySQL.com binaries.

Of interest to lots of folk, is Wordpress stats (you get them with your own install, thanks to the Stats plugin). There is about 150GB of data for stats, that enter MySQL every month, and the data is queried multiple times a second. Wordpress stats currently are based on a per day basis, but real soon now, you’ll see hourly stats. So you can even switch when your day ends, because chances are, you’re not based in GMT.

Wordpress has about 90%+ reads, so the single master multiple slaves replication methodology works well for them. They’re moving to solid state drives, which is giving them more capacity to their current SAS solutions, since its all many tables, MyISAM, and it fits their workload model really well. Moving to SSDs is interesting - if you weren’t at the MySQL Conference, you should definitely catch the video from Andreas von Bechtolsheim, titled The Solid State Storage Revolution. Andy is a co-founder of Sun Microsystems.

Off camera, Barry also told me that they ran HP hardware, and he gave me the tale of how PollDaddy got a new heart - i.e. they moved from .NET/SQLServer to PHP/MySQL.

So, here, I can’t wait for hourly stats to come to Wordpress. And I’m most interested in seeing what comes out from this (via Matt Mullenweg’s blog post):

There are some new developments in the WordPress world, namely that I think it would be possible to add support for databases other than MySQL without changing every $wpdb call or breaking any plugins or themes. It won’t be easy, but the coolest stuff seldom is.
Danesh Manoharan: Another Malaysian URL shrinker, lynx.my

Previously, I covered xs.my . Today it’s lynx.my , another Malaysian based URL shortening service. Check it out.

However, unlike xs.my, lynx.my does not generate a random URL string for you. Instead, you have to provide your own shortened string. While this is good, I see it coming back to bite it’s users when they discover that their string had already been used. This alone might motivate users to move to other services which automatically generate random URL string.

Danesh Manoharan: P1 WiMAX Signal Strength - May 6th 2009

Posted: May 5th, 2009, 12:39am BST

My P1W1MAX signal strenght. Pretty pethatic!!

RSSI: 63dBm –> Other are getting 30 +- dBm

CINR: 13 dB –> Others are getting 60 +- dB

TX Power: 5+- –> Other are under 10. (Not too important)

Called P1 up, need to call them back soon to carry out some “fine tuning” to improve my signal. Thank god their support speaks English well…. unlike Streamyx!!

Take a look at the signal map below, my house is smack middle in the pocket(below the compass) where there is almost no signal.

It’s weird how the base stations are deployed here. According to P1 more base statioins are coming up soon in the area so hopefully I’ll see some improvements.

Are you on P1 W1MAX too? What’s ya signal strength? Need the modem login?

Yong Yoon Kit: MyNPL ISSC 2009 - Feva Division as 1st Runner up

Posted: May 5th, 2009, 5:30am BST

Tags: [edit]

Having picked up paintball only about 3 months ago, I'd never have thought I'd be involved in a major tournament anytime soon. It all started when my cousin introduced me to a bunch of new but really keen paintballers who practise in a field very close to where I live. They only started late last year, but have since invested significantly in purchasing all the gear AND electronic (meaning: fast) markers ("guns"). They were keen enough for weekly sparring practises which was good for me. Learning the ropes, and how to handle the field.

Our first action as a team was in a mini, unofficial tournament in KKlub Kombat Zone, which is where we normally play in. We played as team "Feva Rookies" and came 3rd: a podium finish, but it has to be told, there were only 4 teams participating. So it really wasnt that amazing a feat. We won a Kombat Zone ceramic mug, and a whole box of 2000 pellets to share. Team Marksman Alpha won the tournament then.

Then I asked if we were going to try out the MyNPL International Super Seven Championship to be held on the 1-3 May. There was general interest, but until the last week of the deadline, the consensus was that we were not ready in using the regularly sized fields. Kombat Zone is approximately half the size.

Surprisingly, I got a call from Gilbert, our team Manager one night to submit our details. He pulled everything together and registered us for the tourney. Not only that, eventually he managed to get "Bro" Ariffin (+6019-312088) from Kombat Zone to sponsor our team! Thus the team "Feva Division" was borne.

So after pouring over the Field layouts which was available online, and a 2 hour team meeting, we thought we were ready for the grueling 3 days of the ISSC.

On the 1st of May, we arrived early in the morning, registering and checking out the area. Because we were mere Division 4 (or "Young Guns" division), we had to share a canopy with two other teams. It was rather cramped. The Division 1 teams were already at each other in Field 1, while the Division 3 teams were at Field 2. We had to wait till 12pm for our first match.

We didn't do too well. But we didn't do too bad either. There were only 10 teams registered in D4, and one didn't turn up. So we only had to beat one team to stay in the competition for the knockout stages starting with the Quarter Finals. We lost 3, won 2, drew 2 and won by default 1. This gave us the preliminary position at #7.

At least we made it to the next day!

Personally, I had a great time at the later part of the day. I was trying things I learnt observing the more experienced teams exploited throughout the tournament. How they waited in the snake, moved back and forth the knuckles avoiding the pellets. I played about 3 games in the snake and was quite comfortable. However I didnt move too much, just around the first and second knuckles only. This position however had access to a large part of the field. The centre back, carwash, spike and hammer was always available for picking off. I also managed to hit someone on the left mid can in one game.

Unfortunately for the Quarter Finals (final 8), we were up against the 2nd best team called "Infidelz". Only started a year ago, they are already "D4 veterans" having competed in two other MyNPL tournaments, reaching podium placements then. They did extremely well in the prelims, and perhaps due to the fatigue at the end of the long day, we managed to draw with them (I took out someone on the break, and traded out with the snake player.)

So for Saturday, the Quarter finals is setup as the best of three. No points, either total elimination or capturing the flag within the time period.

This is when Verat "Conquest", our team captain, architected an ultra high risk and aggressive plan of running down the field and taking the enemies out by surprise. The Ultimate Feva move. So we tried it out on the first game of the Quarter Finals against the technically strong team Infidelz. I ran down the left Dorito side with markers blazing, unfortunately halfway down, my bolt jammed. As I looked down to pull it back, I got hit squarely in the mask. Henry too was out, with similar problems with the mechanical house marker. I was walking back dejectedly to the dead zone, thinking it was the end of the plan. Then I noticed our right flank making great progress with Gilbert "Aquaman" cleaning up the last remnants of Team Infidelz.

We pulled it off! It was really fast, no more than 45 seconds. Super aggressive, Feva style.

The second game was slightly less quick, but aggressive nevertheless. We won that too. With two wins, we managed to knock out the mighty Infidelz!

Unlike the grueling 1st day where we had to play 8 matches, Saturday had only the Quarter Finals scheduled. So, for the Semifinals, we had to wait one more day.

I spent the rest of Saturday sleeping.

On Sunday, we arrived at 7am to get ready for our first match against team "X-O Dust." They did extremely well in the preliminary rounds, and rose as the favourite, amassing 597 points with 6 wins. They did well in the last MyNPL event in Johor reaching the Quarter Finals.

We didn't expect to progress further, but were determined to put up a fight.

I sat out the first game, with Mervyn "Blaze", our import from Team Marksman / Dangerouz Dragonz / Werdna Kids fame, covering the Doritos side. We decided to storm the enemy again, and managed to do it in style: We wiped them out without dropping a player.

The second game I managed to be part of the action. The plan was to push aggressively as well. I made it up to the 50, but got shot out. Fortunately SanRise took my lane and sneaked into the wedge to pick off the players who thought that it was already clear. Then we started dropping players, and it was a brilliant move by the lone Conquest who moved up the snake tape to methodically take out 2 bunkered guys, and finally trading out with their last player. This meant the game ended as a draw!

I was out of the third game as well, and watched on helpless as our team got thrashed. It was XO Dust payback for the first match by wiping us clean with all 5 of their players remaining alive. So with a Win, Draw, Lose scoreline, it only meant the nerve wrecking One-on-one decider!

We chose SanRise to represent the team. He calmly stayed in the center back can while the XO Dust player moved swiftly up the field. He finally settled on the Hammer, and snapshot behind the Dorito. It was a thrilling minute which felt like 30 while team Feva huddled looking on. Then the Marshall's keen eye spotted a small splatter on the XO Dust players lower left leg and shouted "Ouuuttt!" and we cheered!

We were actually through to the Finals!

The time was about 10:30am and the Finals for all divisions would only start at 1pm. This meant a long time to wait out. We had an early A&W lunch and relaxed by the players paddocks. The weather was not as hot as Friday, and we had more room since the other teams who did not make it vacated their spots.

We also had to think about the new field. Field 1 was played by the Div 1 and Div 2 teams. Over three days, this meant that it was literally covered with paintballs. The amount of paintball pellets used is really quite extraordinary. This also makes it very slippery to run on.

We had a look at the field, as the marshalls allowed us to walk it. The snake side was extremely exposed with very few bunkers covering it. This put a damper on any fieldwide aggressive moves.

Our opponents were team "Destructo". They too did not expect to advance this far, and only qualified the prelims one place above us at #6. They were only formed 1 weekend before the tourney. So it was a match up of the underdogs. They however had an excellent snake player who was deft, sneaky and deadly.

So our first game, we played defensive. We bunkered in, forming a rough W. Ultimately with less planning and understanding of the field, we didn't choose the right bunkers and were easily picked off from the sides.

With not much to lose, we decided: its Feva Time. Aggressive play for the second game. Having to cover the snake side, this meant I had to run down a very exposed area of the field. It meant certain death, but it would be a small sacrifice for my other team mates to pick off the distracted and disoriented enemy. It worked, with our last player Aquaman again deftly clearing up the debris. Fortunately for me it didn't hurt too bad.

With the scores even, we could either play aggressive or defensive. We decided to go all out. Unfortunately this time, pulling the same trick twice against a smart team did not work, and we were shot out as fast as the last player ran down the 50 yards. As I turned out of the field crossing the tape, their Left Back player accidentally shot through my mask splattering paint into my right ear. Im still picking out orange paint from my ear.

So it was unfortunate that our aggressive play did not work the last time, but it did provide results for the other times we used against unsuspecting teams. In the long run, nothing beats traditional tactics and building skills in bunkering, snapshooting and team placement. These are skills which we will build up over the weeks and months ahead, but at least we know the fear we can instill in the hearts of our opponents with the Feva aggression.

As a first time tournament, the result of 1st Runner Up (or 2nd place) is really out of this world. It was beyond our grandest targets, and we were truly happy with the result. Not only do we get to get some silver medals, we got some Redz harnesses from Werdna Hol and a team prize of RM1300 cash which really is quite good.
So to my teammates at Feva Division; Mervyn, Gilbert, Verat, Kevin and Henry its been an honour, thanks for the experience and well done!
And thanks to Kombat Zone for the sponsorship. More pics available at Verat's Gallery.

Paintball is fun.
