Selama beberapa minggu ini saya melakukan komparasi antara berbagai teknologi internet wireless, terutama dari GPRS dan CDMA 2000.

Kesimpulan singkatnya, CDMA 2000, bahkan yang 1x nya, mengalahkan GPRS secara cukup telak.
Sebagai contoh, koneksi Internet via Star One secara rutin mendapatkan kecepatan akses 10 KB/s. Terkadang bisa peak sampai 12-14 KB/s. Kecepatan teoritis maksimum adalah 18 KB/s.

Sebaliknya, kecepatan akses GPRS yang tercepat adalah sekitar 5.6 KB/s.
Ini walaupun sudah menggunakan handphone dengan GPRS Class 10 (Nokia 9500), lokasi cukup dekat dengan BTS.
Secara teoritis, kecepatan download maksimum HP GPRS class 10 adalah sekitar 10 KB/s, tapi, sama seperti pada CDMA 2000 1x, ini belum pernah terjadi.

Menggunakan alat GPRS tipe Class 12 (contoh: berupa card PCMCIA) tidak meningkatkan kecepatan download, tapi bisa meningkatkan kecepatan upload s/d 2 kali lipat.

Kecepatan akses ini sebetulnya masih bisa meningkat jauh lebih tinggi lagi.
Contoh; jika ada provider yang menyediakan fasilitas EDGE di BTS nya, maka Nokia 9500 (EDGE Class 10) bisa mengakses Internet dengan kecepatan maksimal sekitar 30 KB/s.
Untuk CDMA 2000 malah lebih seru lagi, dengan CDMA 2000 EV-DO, maka kita bisa mendapatkan kecepatan maksimal sekitar 387 KB/s ! (= 3.1 Mbps)

Kesimpulan ?
# Paket akses internet Star One 1GB/bln = Rp 200-ribu patut diperhitungkan oleh mereka yang membutuhkan akses Internet berkecepatan tinggi. Ponsel CDMA yang bisa saya rekomendasikan adalah Sanex SC-7090.
# Ada provider yang menyediakan EDGE atau tidak ya di Jakarta… ?

Pagi ini saya membaca Kompas, dan ada sebuah artikel yang mengabarkan bahwa SBY menerima gelar doktor ilmu politik dari Universitas Thammasat. Disitu dikatakan bahwa Universitas Thammasat memberikan gelar tersebut karena, “… dianggap sebagai seorang pemimpin hangat yang memiliki visi dan integritas serta dikenal karena komitmennya dalam memperjuangkan demokrasi dan perdamaian”.

Harapan saya sama seperti Eko, yaitu SBY bisa menyikapi kasus Herman/Priyadi dengan arif, begitu beliau mendapatkan informasi yang lengkap mengenai insiden ini. Membaca artikel tersebut, saya kembali berharap demikian.

Karena itu saya gembira mendapat email dari Carlos Patriawan di milis teknologia@googlegroups.com, yang memberitahukan bahwa SBY tidak marah karena hal ini / foto tersebut. Juga, “… Presiden menganggap tidak perlu dilakukan penyelesain hukum”.

Rasanya kalau demikian, kita bisa menganggap kasus ini selesai dengan baik ya 🙂
Mudah-mudahan saja para aparat pelaksana juga berpendapat demikian.

Congratulations to Herman & Priyadi. Semoga mereka dan keluarganya kini sudah bisa merasa tenang kembali.

Karena kasus Herman Saksono baru-baru ini, tentu saja Roy Suryo jadi banyak berkomentar, sebagai salah satu pihak yang terlibat. Namun, sebagaimana biasanya, ada saja kesalahan yang dilakukannya :

1. Herman Saksono bukan lulusan University of Melbourne
2. Priyadi tidak pernah kuliah di jurusan Teknik Informatika ITB
3. Priyadi tidak diperiksa intensif oleh Polda dan Kominfo, melainkan hanya diundang diskusi oleh Judith MS.
4. Priyadi bukanlah pemilik domain name roysuryowatch.org

Mudah-mudahan di masa depan, media massa bisa mengkutip dari pakar yang lebih teliti, dan tidak sedemikian banyak kesalahannya dalam menyampaikan fakta.

Amazing… I know that there are still people out there who optimize software down to the processor-level, but to actually read the story of one of them really brings back memories.

Back when PC-XT (Intel 8086 / compatible) still rule the world, every processor tick is precious. A tick saved in a loop can be very visible to the end user. Also, there were no drivers – most of us (programmers) access the hardware DIRECTLY.
Feeling the chill down your spine ? Yes, that’s how many of us code back then.

When others busy playing games, I was busy hacking the games. I think I even managed to package a few of those hacks and upload them to a local BBS.
When I coded a Sysinfo-like software for a competition, I found out that the screen benchmark routine was very slow. I changed it to access the video card directly, and it ran way faster afterwards. Also developed other stuff; hard disk auto park TSR (Terminate and Stay Resident), etc.

Let me tell you; it’s great joy to see your creation (software) performs excellently. Even though I was almost alone while doing all of those (no Internet yet at that time, not enough people with similar interest on local BBSs), I still managed to accomplish a few things.

It’s no easy task, however. A small mistake can send you in a goose chase for hours, while you’re trying to spot the error in the assembly language. Turbo Debugger was very helpful, but with limitations. A great help came later when a friend informed me of SoftIce. Way more powerful than Turbo Debugger, it’s also harder to use.
Sometimes I also had to resort to DEBUG, the built-in debugger from DOS. The ultimate pain 🙂 however, in certain situations, it can be quite handy; especially because we can script it in a batch file (.BAT) and it’s available in virtually all PCs (since it’s bundled with DOS).

Then I saw a software package, I forgot what it was called, which let us code by creating the flowchart on its GUI (Graphical User Interface) – instead of coding by hand. It came on 10 (ten) 360KB floppy disks. Took a long time to install, ran very slowly on my PC-XT, cost me a fortune, and ate up almost all available DOS memory.
But once it ran, I realize that this is the future of software development.

Years later, Visual Basic showed up, and pretty much revolutionize software development on PC.

It has been about 10 years since I created code that access the hardware directly. So I’m very touched that there are still people out there doing it, enjoying it, and actually profit from it. Simply amazing.

Regarding the software competition that I mentioned above – I was sent by Al-Azhar (AA) High School as their representative, along with my friend Isa (Istiqfar). Actually, we had to beg so AA will allow us to participate (not sponsoring, mind you) in the contest – the two of us were pretty much the only ones that can work with computer at the moment, and they didn’t have any interest on IT. AA were more interested to sponsoring students on things like basketball, bands, sports, etc.
We were very happy when they allow us to join in the competition (at Kanisius High School). On top of my head, we prepared everything ourselves, with our own money and equipments. AA just allowed us to list ourselves as AA student in the competition.

We were awed when we arrived in the event. Scores of students, mostly from Christian schools, showed up their projects. Most of them work in teams. Many of the projects were multimedia-related; this is amazing considering 8-bit SoundBlaster card costs an arm and a leg at the time, and it’s very hard to find the reference on how to access it (I finally managed to purchase a book on the topic several years later when I visited Singapore). Almost all of them were accompanied by their teachers, and their hardware provided by their school.
In contrast, we brought our own PCs there, no teacher, only 2 of us, and showing up a software (Sysinfo) with no multimedia capability.

I’ve lost my confidence at the time, and quite ashamed by our situation. Then the jury came. I showed the software, and tried to present it as best as I could. Alas, I’m not a good presenter (even now), and it doesn’t help when you’ve lost your confidence.
The presentation was soon over, and not much comment from the jury. Of course, bells and whistles considered, a Sysinfo software is plain uninteresting. It’s just not shiny enough.

However, then he spoke with me, encouraging me to keep on learning.
I was surprised, since I didn’t see him talking like that to the other kids. He wore a name tag, but I couldn’t remember his complete name though. I think it’s “Samaun” or something.

To this day, when I was feeling down, the memory of that event always cheers me up again. It’s because it was my inspiration to develop my career in IT. I’m forever thankful to the jury in that event.

btw; I sure hope AA now has (MUCH) better IT education programme.

Right, back to the topic – I wish I can do direct hardware coding again, but it’s just not feasible at the moment. Perhaps when I have more time, some time…

Ability to utilize Google effectively should be a requirement to any IT employee. This is because it will enable him/her to tap into the massive information/knowledge database, which we call Internet, efficiently.

I’ll let a secret out – in my previous job (at Birmingham City Council), people thought I know everything. The real truth is, I know some stuff, and I work harder that some people; but my ability to use Google helped me significantly to accomplish my missions on / before deadline.

Therefore, the following guide should not be ignored, since this will enable you to do things you may not realize possible .
Print it out, and put it next to your computer. You may just be able to impress your Boss with your sudden “enhanced skill & knowledge”.

Note that this is not spam. This is simply the BEST deal on dedicated servers I ever found.

123-reg.co.uk now offers several dedicated servers packages, and I’m sure many would find the first one very attractive for several reasons:

1. It’s already fully loaded; webserver/database/DNS server/etc, already setup and running.
2. Very easy to use: you control everything listed above via a Control Panel
3. Flexible; you can also request root access should you need it. However, this will make the server to become unmanaged, because otherwise, 123-reg’s staff will take care of the server’s maintenance (updates / upgrades / patching / etc). This brings us to the next point:
4. Managed dedicated server at only 39.99 poundsterling per month is simply unheard of. If you need such kind of service, this is the best of such deal.
5. True unmetered bandwidth; where others said so but in reality have artificial limits and WILL kick you out if you use too much of their (unmetered) bandwidth, 123-reg is able to truly offer it because of their partnership with PIPEX. Also,
6. True unmetered bandwidth at only 39.99 poundsterling per month is simply unheard of. So if you need such service, you can’t go wrong with them.

I’m currently is weighing on whether to move from my current hoster to 123-reg. I don’t need the unmanaged service, in fact I’d rather have full control of the server, so I can learn the nitty-gritty details of maintaining a live server on the Internet.
However, the unmetered bandwidth is VERY tempting.

I’d probably ended up ordering one …

From our favorite technology company, Goo gle, here comes 10 tips on how to get the best out of your skilled employees.

There are excellent ideas there, and managers would do well to consider them.
For example, “hire by committee” is the kind of ideas which would make people goes “why didn’t we think about it”. It just makes sense.

They seem to like Peter Drucker, and do exactly what Drucker said – “cater to their every need”. At their office, you’ll be able to find gyms, laundry, car wash, dry cleaning, shuttle bus, etc. Their staff, even the unmarried ones, can get all (literally) their jobs done at the office. A serious productivity boost, and something that a company as big as them can afford, considering the benefit out of it.
As an engineer myself, I know that sitting all day and pushing your brain to the limit tend to deteriorate your body. I visit a gym regularly to keep me healthy, but having the gym inside my office would really, really help indeed.

“Encourage creativity” – this may sound cliche, but their implementation of it certainly is far from it. It is, shall we say, very creative.

“Data drive decisions” however, might not always be possible. Certainly you’ll need to strive for this, but there WILL be situations when there just isn’t enough data available to make a fully informed decision. Make no mistake, as a manager, you WILL be in this situation.
There will be situations where, for example, there are several options available. To make things worse, taking the wrong decision may harm the company.

This is where another tip comes in – “strive to reach consensus”. You’ll need to involve your people on such important decision. Let them have their say heard.

However, when you fail to reach a consensus, it’s a manager’s job to decide. The buck stops at him, and so he must make the judgement, based on whatever data he has.
The employees must obey AND fully committed to make the decision a success, even if they disagree with it.
This is how a good team works.

This, however, would only be possible with a solid team, where each and every one trusts each other. To accomplish this, you’ll need to “communicate effectively”.
Team members need to be able to communicate freely to build trust. Don’t make it hard for them to do so.

Anyway, go now and read the article. You can’t afford to miss it.

Just returned from a client, yet another internet cafe converted to Linux / LTSP solution. Even after paying my consulting rate, he still saved a LOT of money by doing so, and therefore shortening the time for ROI drastically.

I’ve had a few problems though with Mandriva 2006. But it’s nothing serious, just glitches.
Some are quite strange tho. Like, how the start menu shows the image “KDE free 3.4”, but there’s no KDM in the display manager choices (there are only GDM and XDM ….)
Couldn’t create icons on the desktop – but this is probably a restriction on root account, since we can do that just fine on normal accounts.

Had problems with Compaq machines with ESS Audio drive chip (ES1869F), got around that by using sb module, thanks to this post.
But the strangest is 3Com’s 3C900B-TPO network cards, they just won’t boot to the LTSP server. When replaced by other NIC, the machine boots up normally into the server. We might have to replace these NICs.

The DHCP server doesn’t work properly, workstations are unable to get IP address from it. A friend then suggested that we used older version of dhcpd, to be exact, from Mandriva 2005. It then works without any more problem.

Mandriva 2006 seems to be quite a nice distro. Hopefully it’ll prove itself stable and reliable too for this server role.

God I am so tired. Gotta rest.

Wow… very interesting 🙂 a few articles: how to survive a riot (does happen in Indonesia, so quite relevant), how to stop a car with no brakes, survive a plummeting elevator, etc. There are a few strange ones too – how to foil alien abduction, jump from rooftop to rooftop, etc … ha ha.

All in all, makes for very interesting reading. And who knows, it may save somebody’s life too.

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…?

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.
