Google loves Firefox

I’ve been wanting for some time now to help advocate / spread / advertise Firefox, especially on this website.
Previously, I’ve registered my family as donater to Firefox campaign. The Spread Firefox team then was able to purchase a 2-page advertising on New York Times. (click here to download it as PNG/PDF file)
But then I got busy with other things.

Then I noticed that Google has opened up their Firefox referral program to international AdSense publishers.
Wonderful - you get to advocate for your favorite browser, and got paid at the same time.

So, there goes the little Firefox button on top-right side of this blog :)
I noticed that the buttons are pretty small, most are only 2 - 3 kb in size. So I hope it won’t inconvenient you too much.

Right, now, does anyone knows how to make AdSense adverts show up only on English contents…?

Tips beli komputer: pilih power supply yang bagus

Jika Anda ingin membeli komputer baru, jangan lewatkan satu hal: power supply yang bagus.

Kebanyakan orang melupakan power supply ketika membeli komputer, sehingga penjual komputer bisa memasang power supply murahan, sehingga keuntungannya pun jadi meningkat.

Namun, power supply berkualitas rendah sangat berbahaya, karena ketika rusak, maka komponen komputer yang lainnya dapat turut menjadi rusak juga - motherboard, prosesor, memory, hard disk, dst. Karena kesemuanya tersambung ke power supply yang sama !

Idealnya, power supply yang Anda beli bisa mematikan komputer secara otomatis jika rusak.
Masalah yang paling sering menimpa sepertinya adalah tewasnya kipas pendingan power supply. Maka power supply mengalami overheating, sehingga menghasilkan output yang tidak benar.

Masalah power supply ini bahkan juga menimpa Xbox 360, yang baru saja dirilis oleh Microsoft.

Power supply berkualitas bagus kadang hanya berbeda harga sedikit sekali dari yang murahannya, namun dapat melindungi investasi komputer Anda yang bernilai jutaan rupiah.
Jangan lewatkan ini.

Lego Mindstorm: meet FischerTechnik

When I was still in UK, I happened to meet a friend in Sheffield. He impressed me with a lot of things and ideas, but one thing stood out - his kids are messing around with Lego Mindstorm, and it was the first time I encountered it.

I thought I’d buy it for my kids, but it’s rather hard to find. Then I got busy with other things.

Today I read a post on Slashdot.org regarding Mindstorms and lack of its popularity in Lego. Thankfully, a poster told about a (seemingly worthy) competitor - FischerTechnik

When my kids have grown up a bit more, I’d like to buy a few pieces of this, and get them started in (robotics) engineering; and see if they’re interested on it. If not, I can always put the kit available for loan, to whoever could use it.
Heck, it may be a good idea to create a robotic club, so my kids would be more enthusiastic about this (since they’ll be doing it with others).

If you know of other good alternative to Lego Mindstorms, do feel free to comment.
Thanks.

Mesin Diesel: antara mitos dan fakta

Salah satu pertimbangan saya dalam membeli Kia Carens II (yang ternyata sucks itu) adalah karena mobil tersebut menggunakan bensin - bukan solar; dimana saya kira bensin adalah lebih ramah lingkungan daripada solar.

Ternyata, kelihatannya bensin itu justru jauh lebih beracun daripada solar, menurut artikel di Intisari tahun 2000 ini
:(

Sekarang saya sedang berencana untuk mengganti Kia Carens II dengan sebuah mobil diesel, mungkin Panther atau Innova (versi diesel).
Ideas most welcome.

Dulu saya juga pernah menggunakan mobil diesel, yaitu Toyota Previa. Tapi saya selalu berusaha menjaga agar emisinya jauh berada di bawah ambang batas aman. Mobil ini sangat menyenangkan dalam pemakaiannya. Sayang harganya disini jauh lebih mahal daripada di UK.

Mobil diesel jadi semakin menarik saja; lebih ramah lingkungan, irit, bandel, nyaman (terutama yang telah menggunakan teknologi EFI / common rail), dan tetap berperforma tinggi (terutama yang ada turbo-nya).
Saya kira, kalau APV atau Xenia mengeluarkan versi diesel, mobil MPV bensin bisa overstock gila-gilaan karena tidak laku nih :)

Anyway, selamat membaca:

Norton Internet (Useless) Security

Tuesday, November 29th, 2005

My uncle came today with his laptop - he said that he suspect it’s infected with some kind of virus.
Took a quick look, and found Norton Internet Security. I instantly got the hunch that this will take some time to take care of.

Indeed… took me about 4 hours to fully clean the laptop. The laptop was in a very bad condition; it was infected with about 130+ viruses. Norton Internet Security however didn’t give a single warning. Everything is okie-dokie, according to it. Totally useless junk.

The Internet connection was hosed too. Looking around, found on asus.com website that this is caused by doing a system restore. Yes, the virus is messing around with XP’s system restore feature, and while doing it managed to cripple the modem too.
So I downloaded the 10 MB modem driver (no small feat here with Indonesian’s puny internet access), uninstall the modem, and reinstall it again.
Voila - working Internet connection.

Back to Norton Internet Security - I’ve decided to call this piece of junk “NOrton internet Useless SEcurity” (NO-USE).
I uninstalled it completely, then installed AVG anti virus and ZoneAlarm firewall. All free, and all works MUCH better than NO-USE. Shame on you, Symantec - and you call yourself a security company ?

A few years ago I got NO-USE for free from my bank (Barclays) when they first introduced their online banking facility. It was a trash back then - it destroyed my Windows installation so thoroughly, I had to do a clean reinstall.
It has managed to do a bit better now, I didn’t have to reinstall this laptop. However, letting viruses slip past its firewall, and then failed to spot 130+ viruses in the laptop ?
It still sucks, big time.

Stay away from it. You’ll thank me for that.

Addendum:
Here’s another reason why it sucks. Unbelievable.

Sejak beberapa waktu yang lalu saya mulai tertarik untuk mencoba development di Java. Yang pertama-tama saya lakukan adalah mencari IDE (Integrated Development Environment) yang bagus untuk Java, karena ini akan dapat sangat membantu proses belajar saya.
Setelah mencari beberapa waktu, saya menemukan sebuah yang baik, namun harganya sekitar US$ 500. Maka rencana belajar Java saya tunda dulu ketika itu.

Kemudian saya menemukan bahwa ternyata Sun kini sedang menawarkan IDE Java mereka untuk di download tanpa biaya - padahal harga retailnya nyaris mencapai US$ 2000.
Anda dapat mendapatkannya dari link ini: http://developers.sun.com/members/promo/freetools/index.html

Jika Anda belum menjadi anggota SDN (Sun Developer Network), maka Anda akan perlu mendaftar terlebih dahulu sebelum bisa mendapatkan penawaran ini. Pendaftara SDN cepat (hanya mengisi 1 halaman form) dan gratis.

Semoga bermanfaat.

Accident

Friday, November 18th, 2005

On the 15th November 2005, I was involved in a motorcycle accident.

I have finished my work and asked one of my staff to drive me home on the office’s motorcycle. I didn’t expect anything since he’s quite polite and well-mannered.

It started when a bus stopped on our lane. Clearly, this means that there’s another vehicle in front of that bus, most likely will be entering the opposite lane. The bus was giving way to this vehicle.
However, instead of stopping, my driver was pulling the throttle to the max, and he tried to overtook the bus. My heart stopped pounding for a while, and I thought that this would be my last moments on earth.

Thankfully, the vehicle was entering the other lane slowly, and we passed by unharmed. If only that car was going a bit faster, we’d have been dead, or at least severely wounded.

I was just about to shout at this idiot when I saw something else - there’s a girl riding motorbike in front of us, and she’s going to do a right turn.
Unfortunately, my idiot driver, probably still feeling victorious for being able to overtake so many vehicles in one go, again accelerated the bike, and tried to overtake her motorcycle from the RIGHT.

Truly, there’s no limit to human’s stupidity.

I was only able to shout “awas!!” (watch out), and the next thing I know, we were thrown pretty far away from the collision spot.

I was injured on my left arm, left leg, and minor injuries on my right leg.
There are bruises in several places. Also I was unable to use my left leg without feeling sharp pain in it.

Actually, I should suffer worse injuries on my left leg, but I was saved by the PDAir casing that was being used to enclose my Nokia 9500.
The case was badly damaged, many deep scratches and it won’t close anymore. However, my Nokia 9500 escaped the incident with no damage at all. And if it’s not there, then my upper leg would have been torn apart. Thank God.

The girl that he hit was a bit injured. When he was more concerned about my condition, despite me already saying I’m alright, I shouted to him to escort her straight away to the nearest hospital.
Thankfully, she was diagnosed only with minor injuries, and discharged from the hospital before us.

A bit more about this incident later, must rest now.
If you find it hard to contact me this past few days, here’s why. Apologies, hopefully you can understand my current situation.

A few photos:

My injuries : warning, some may find these pictures depressing. Don’t click if you can’t see rather gory images.

Wound on my left arm
Injuries on my left foot
Minor injuries on my right foot

My PDAir case:

The scratches, actually it’s pretty deep. Makes me shudder, when I remember how strong the metal is.
The whole picture
Now it can’t be closed anymore

My left leg took most of the weight when I fell, the trouser was ripped apart. Thankfully, there was the PDAir case behind it, acting like an armor for my leg.

Here’s for PDAir case : Highly recommended !
