If you want to sustain excellence over a long time, you’d better come up with a system that works well. Anyone can sprint for a little while, but you can’t sprint for forty years.

I found interesting pictures in Royal Pingdom website.

It says that CERN’s Large Hadron Collider (LHC) will be producing roughly 15 petabytes of data each year (15,000,000,000,000,000 bytes). In other words, the LHC is not only huge in physical size (filling a 17-mile long underground path), but it will produce enormous amounts of data for researchers to bite into.

Here are some of the pictures(Warning: High-res picture inside)

Apple diberitakan telah menarik kembali adapter untuk iPhone 3G pada hari Jum’at, 19 September kemarin lusa.

Seperti dikutip dari Cnet news, hal ini disebabkan banyaknya laporan bahwa adapter tersebut cacat produksi dan dapat mengakibatkan arus pendek yang dapat menyebabkan kerusakan pada iPhone hingga kebakaran.

Namun Apple sendiri menjamin bahwa penarikan tersebut akan diiringi dengan penggantian adapter baru yang telah disempurnakan tanpa biaya sama sekali.

Hingga berita ini dilansir dari situs resmi Apple, belum ada laporan mengenai adanya korban jiwa karena cacat produksi ini.

Apple mengeluarkan produk inovatifnya iPhone 3G beberapa saat yang lalu sebagai tanda bahwa Apple Corp. tertarik untuk bersaing di pasar mobile phone. Apple mengeluarkan teknologi yang dimilikinya antara lain layar multi-sentuh, kemampuan memainkan musik mp3, hingga kamera built-in resolusi tinggi 2.0 MP di produk mobilenya ini. Meskipun ini produk pertama dari Apple, sambutan pasar sangat luar biasa sekali.

Meskipun cacat produksi, para pengguna yang baru saja membeli iPhone setelah hari Jum’at kemarin. iPhone dengan tanda lingkaran hijau kecil di atas kemasannya menggunakan adapter yang sudah disempurnakan.


Sayangnya produk ini belum ada di Indonesia :p

After three key concept in my previous post. Now I will describe what the others concept to securing information.

4. Authenticity

in computing areas, you have to make sure that people who have access to certain information are eligible to access it. Username and Password are the basic things from this concept.

5. Non-repudiation

This is mean, you can’t denied any transaction written on the computer. For example, if you has bought something from popular E-commerce site, in the future you denied that you ever bought something from there. and this problem goes into the law, the court will ask for the log-file of your transaction as a proof. Log files can be used as a proof <– this is mean of non-repudiation. Nowadays, digital signatures are commonly used as part of non-repudiation.

6. Logical Security

Wider area to securing information. Like username and password before you login to your computer.

8. Physical Security

Commonly use of biometrics for authentication (e.g. Fingerprint reading, Voice Recognition etc..)

Turning Research into Real World Business: A critic to Indonesian Government September 17, 2008

This is the second time Indonesian government have a big failure in research area. Of course research always possible to fail, but this fail is too big since it’s become national issue. Its an ironic the guy who cause the failure is the same guy. We all knows that only donkeys can fall in the hole for twice. What I mean is about Supertoy Rice.

It’s a normal thing if Indonesia wants to solve food problems. You can produce more rice within the same area. But research has a method to follow or your research will be either over budget or totally failed. I’m just a student who trying to give my opinions so this problems will not occur in the future.


Information Security, what to protect? September 16, 2008

For some institution(business, government etc.) they need to secure their information from outside threat. This threat could be from anywhere. It can be from either from outside or inside. They are not trying to protect the hardware. When the hardware is broken or stolen, you still can find its replacement on the market; They also not trying to protect their software, its always can be reinstalled again, even it takes time. It is the information they were trying to protect. Information of their customer, civilian records, financial records. Most of it are stored within popular office format such as Word, Excel, Access or even in database like MySql, PostgreSQL, Oracle or any popular database vendors.

Here I’m trying to describe what is the key concept how to secure this kind of information.

1. Confidentiality

Confidentiality means that you are trying to protect some information from unauthorized access, such as hackers, crackers, and any people/subject that don’t have rights to access sort of information you have.

2. Integrity

Even it’s protected, you have to ensure that your information is not altered by mistake or accidents. So the information need to be authorized first before you can make some changes on it.

3. Availability

It’s useless if you are protected something but that information is not available to you when you need it.


Those key concept are well known as CIA concept. I will adding more key concept in my next post.
