My article goes Arabic!

Without further comment, here it is http://arlinux.110mb.com/lgazet/vim-m.php. It's actually an Arabic translation of LG 2 cent tip written by me about couple months ago in 2007. And Happy Idul Adha... regards, Mulyadi

Finding frame rate tester for Linux?

2007-12-24T20:36:00.000-08:00

Breaking from my usual routines on posting Linux internals issues, I post something different right now. Since I am also a (near hardcore) gamer, I always pay attention on recent game releases and development. Well, not so intense like the old days, but I still keep my eyes on it. And for gamers like me, what's the important thing to watch for? Cool GPU? Of course! Feature rich multimedia

Peeking into kernel internals with SystemTap

2007-12-07T20:58:00.000-08:00

Just to remind myself and others who are interested in kernel instrumentation. Long time ago, perhaps we did it via manual code modification followed by kernel recompilation, or...uhm, have you ever done syscall hijacking or something like that (ok, it sounds dirty...) ? Now, here comes SystemTap. Some people call it Dtrace-clone. You can find it here. And here you can read a simple example on

observing kernel variable's content with gdb

2007-07-04T09:39:00.000-07:00

I put it on my blog, so at least some people could have the alternative place instead of digging kernelnewbies archieves. This is a raw summary of discussion between me and Robert P.J. Day. First, an extensive explanation from Robert: ok, here's what i've learned so far, and i have to admit, a little of it surprises me. to explain what i'm doing, i've just started to write a tutorial on

Copy of feedback Jeff Dike gave me...

2007-06-12T01:24:00.000-07:00

Hello everyone. Recently I wrote about GCC on Onlamp and some folks gave me feedback. I believe this will be a valuable piece for everybody, so I put it on my blog. The same comment is also posted in Onlamp, but I screwed up the HTML output. For those who got trouble reading the text there, I put the corect version here. This one I got from Jeff. Sharp criticism... The text written in italic is

The Man named Ulrich Drepper

2007-02-08T11:46:00.000-08:00

You don't know who he is ? Just for intro, he is one the Glibc maintainer. So this guy deals with one of the most wanted component inside Linux. But what I found interesting from Mr. Drepper isn't really about his skill, but how he comments on something. For example, taken from his posting: "If the title promises the latest tactics, why waste time on ancient history? When promising details, why

An enlightenment about shadow page table

2006-12-23T02:10:00.000-08:00

Lately, I got trouble understanding why Virtual Machine Monitor (hypervisors, such as Xen) implement shadow page table. So I entered #osdev in Freenode and got these explanations from these generous gentlemen. Enjoy! (Note: the_hydra is /me) hi could somebody help me understanding what shadow page table really is? from what I read, seems like we do shadow

Dear readers.... I think I read a very good news. I visited del.icio.us and I found this. By the time I read that, my article has been bookmarked by 158 people...and all I can say is "Wow"..

Vini Vidi Vici (participating in local Linux Troubleshooting competition)

2006-11-19T10:01:00.000-08:00

Thursday, November 16th 2006, another normal day for me. OK, that's wrong :) Like any other IT folks nowadays, I spent some part of my free time to browse the Internet. Guess what I found? What? Attending the conference? No no, that just made me feel sleepy and awful. Think again. Yup, I decided to enter the Linux trouble-shooting competition. First thing that came inside my brain was "what the

Someone is watching you (or your work?) :)

2006-11-16T13:33:00.000-08:00

Just a short post... Wandering in WWW, like usual, and I found this blog entry . So, at least I am happy that someone found my work is indeed useful for him/her :) In this paper titled "Distributed Software Platforms for Rehabilitating Obsolete Hardware", my Unix Review's article got cited by some folks from Italy. Hm, this URL is interesting. It's like two ways promotion :) My article

"What does this man do on 1:17 AM"?

2006-04-29T11:15:00.000-07:00

Interesting subject isn't it? Ever think something like that when you work late and you found yourself asking this kind of question? Is it somekind of joke? Irony? Self consciousness over something that hog your life? Everybody has an answer, I believe that and you too gotta believe that you can answer it. So, let's assume someone (or probably me) asks something like that to me... I have many

Jokes from IRC world..... :)

Dear readers :) As you know, anything can be found in IRC. Serious talk, jokes, sex, politics, religion, anything you can spell between A and Z, it's all there :) For me, IRC is like a virtual pub or cafe. I meet new people there, discuss computer stuff, brain storming, or simply just sit and do nothing...hahaha :) two days, I visited #qemu channel on irc.freenode.net. This channel is the

"Batman Begins"...I always love the way it's started.....

2005-06-22T08:03:00.000-07:00

Hello guys, long time no see... Yeah, as you might guess, this is a quick recap about the latest movie I watched this afternoon, Batman Begins. First impression, great ! The producer and director did a brilliant job to give a new style to tell the story about this midnight warrior with dark suit. Previously, I thought that only Joel Schumacher who can do such a job, but I was wrong...as it is

The Road to Sys Admin Magazine......

2005-05-13T05:38:00.000-07:00

Thursday, May 12th 2005.... after 3 months of hard work, my writing about Staircase scheduler was finally finished. Certainly not an easy task, because previously I thought this would be a bit easier than what I had done for IBM DeveloperWorks publication. But it is proved to be totally false..... But let's throw out the "pain side"......here are the "lovely side" 1. Understanding scheduler code

Things I learned from Linux kernel :))

2005-04-12T00:59:00.000-07:00

The title might sounds funny for some people, especially for non "geek" (Hey, I am not a geek, I dig Linux internal for money :) ). usually, when we want to code something into computer "realm", humans bring analogy and perception he has and tranform it into block of codes. But in my case, the reverse happens, looks like I learn several stuffs from Linux kernel (version 2.4.x and 2.6.x). Note:

Iklan dengan sentuhan bela diri

2005-03-25T08:55:00.000-08:00

Ini dia topik omongan paling favorit gw....bela diri ! belakangan gw lihat ada dua iklan yang sangat bagus menampilkan koreografi: 1. Iklan Shampoo Clear 2. Iklan rokok Surya Pro Kebetulan juga, dua duanya ini memakai gerakan-gerakan bela diri asal Brazil, namanya capoeira. Capoeira menurut sejarahnya diciptakan oleh budak-budak di Brazil pada jaman penjajahan Portugis. Karena tangan mereka

"You won't truly know someone until you fight them...."

2005-02-28T12:08:00.000-08:00

The above quote comes from a movie titled Matrix reloaded. For those who don't know what Matrix is or really don't have any clue on what it is, I will explain it a bit. Matrix is a sci-fi movie describing about human race live under computer control. These humans are grown on a very very large field. Yes, grown, not born. And computer (or let's just say robot with superb Artificial Intelligent)

Constantine.....

2005-02-22T04:07:00.000-08:00

No, I am not going to talk about Russian emperor or Russian witch or stuff like that. This is a title of new movie starring Keanu Reeves. here, Keanu reeves plays as Constantine, a supernatural detective who work to "send devil back to the place they belong"...in short...hell :) The interesting things about Constantine are: 1. He was born with unusual gift. He can see devils in their real form

Pemikiran terhadap pernyataan Sekretaris MUI

2005-02-20T18:47:00.001-08:00

Yth Bapak Din Syamsudin dan fungsionaris MUI terkait Sebelum tulisan ini saya lanjutkan, saya himbau pada siapapun yang kebetulan mampir dan membaca tulisan ini agar sejenak berdoa dulu kepada Tuhan YME agar diberi penerangan mata batin dan akal dan dijauhkan dari bisikan setan yang hendak memanipulasi diri kita. Saya sendiri sempat merenung lama dan meminta petunjuk Tuhan agar tulisan saya ini

(Another) Dream come true, IBM DeveloperWorks....

2005-02-02T08:27:00.000-08:00

Whenever I remember how this is started 4 months ago, I always said to myself "Gee, this article is considered to published on IBM DeveloperWorks where top notch writer and scientist share his/her idea. Maybe they are not God but surely they are among the best on earth !" To be honest, the article wasn't planned to shoot for IBM DeveloperWorks. I was targetting to another online publication but.

A (late) new year

2005-01-06T09:26:00.000-08:00

Here we comes folks, year 2005 ! We left behind all the thing we have done, may it be good or bad...all are past, and now...today, we start a new life ! For me 2004 was a great, confusing (or more precisely, frustating), fun and sad year. We call something like this as "gado-gado" or "nano-nano". If you don't understand what I mean, just consider "nano-nano" as a candy with many taste, sweet,

Pengolahan sampah dan kekerasan

2004-11-22T09:42:00.000-08:00

Judul ini sepertinya sama sekali gak nyambung...Apa coba hubungan sampah dan kekerasan? yang satu soal penanganan sesuatu yang merupakan buangan, yang satu suatu tindak emosional pada suatu struktur masyarakat...... Ini dia kejadian yang bikin saya (semakin) geleng2x pada fenomena di negeri ini Masyarakat Cilonjong (salah spell mungkin?) di Bogor, Jawa barat memprotes pemindahan TPA
