原來 ubuntu server 是這麼一回事
Posted on 2008-06-16 • (0)
之前一直看到自己的 server log 投訴 slocate 找不到 /etc/updatedb.conf，原來大半個月都沒有做 file index。奇怪了一段時間，明明那個檔案本來還在，為甚麼會忽然在升級至新版本時清除了 (→ Hardy)。

Linux Hater
Posted on 2008-06-04 • (0)
很久沒有那種找到知音的感覺了。雖然大多數內容都是諷刺或帶憤世嫉俗的語氣，但的確說出了許多 Linux 用家的心聲。以往也想過自己寫些甚麼的 (事實上也寫了兩篇稿給 LinuxPilot，但角度不同)，但就是沒法谷着那一口烏氣去寫出來，要寫也寫不出那麼辛辣的英文語句。
不過找到臭味相投的人，都是多得 [......]

Recovering photos from camera
Posted on 2008-05-26 • (1)
Some of the photos were secretly deleted from my digital camera by a certain guy few weeks ago. Surely, with valid reason, he didn’t like some of my photos. 
Though I have backup of some of them, other newer photos are not backed up, thus only data recovery can come to my rescue. As a Ubuntu partition is available, I decided to gives the tools mentioned in Ubuntu Data Discovery wiki page some testing, all of which are readily installable with apt-get.
My test points to the following conclusion:
scalpelis utterly useless when discovering digital photos, while other 4 tools (foremost,photorec,magicrescue,recoverjpeg) achieve similar degree of recovery, with photorec edging out the other 3.
Though there was an existing test between scalpel and foremost, it only compares their speed, but gives no comment on whether software works or not. Data discovery software must try to discover as much evidence as possible, speed is just marketing gimmick when tools don’t work at all.

The art of file type identification
Posted on 2008-04-28 • (4)
Recently I’ve been working with maintainer of file(1) to merge in various file magic identification floating around on internet. Though I can’t say this is exciting experience (‘boring’ is the better word to use, involving searching for spec everywhere and searching for files to test, except when many proprietary formats are undocumented), such ongoing work allowed me to more firmly grasp how things can improve.

Games on … (ahem) … Linux

Subscribing to HappyPenguin RSS feed might be an error. I just keep reading the same game descriptions over and over (and yawning). Finally, finding myself so bored, I decided to summarize the game descriptions. These patterns should fit more than half of all games listed in Happypenguin:
