yet another notes to myself

Nokia N9

2011-10-24T10:47:00.002+08:00

Friend of mine loan me this Nokia N9
3.9 inches gorilla display
8 MP, dual LED flash
1GHz Cortex A8 CPU
MeeGo OS

I kind of like that there is no physical button in-front, double tap to activate, swipe down to close application, also dim digital clock when the phone is off. The Camera control is nice, I don't use much camera but I probably will if I own this one.

The way they present multitasking and background task is interesting as you can see from the image above, its really handy for navigating between process, although for the browser I don't like the way it split process for every "tab" since I tend to open a lot of "tab. This will clutter the task manager.

The biggest problem is that there are not enough apps to play around on ovi store, but since MeeGo licensed on GPLv2/v3 I hope it will be growing along side its cousin Android in the future

Cleaning up exim4 junk queue

2006-11-21T12:28:00.000+08:00

Sometimes your exim4 queue full of junk email, you can remove it by this command

exim4 -bpr | more
exim4 -bpr | grep [filter-to-get-the-correct-queue] | awk '/^ *[0-9]+[mhd]/{print "exim4 -Mrm " $3}' | sh

Take a Peek at You Current X Display

2005-06-12T23:36:00.000+08:00

From time to time I found my self a need to peek what's happening on my desktop screen in the office or at home (I left my Desktop turned on most of the time). No it is not everyday need, maybe only once in 2-3 month.

possible scenario:

I left office or home while uploading big file using firefox. I need to know whats exactly happening at the end of the upload.
I left azureus turned on when I left home for work. I want to know the progress and maybe add more download to the queue.

x11vnc and the viewer is the answer, simple and works.

Here's what I usually does:
$ ssh myoffice -L5900:localhost:5900
$ x11vnc

from client side (in this case my home machine)
$ vncviewer -encodings "copyrect tight zrle hextile" localhost:0

Pentium M 725 (1.60GHz, 2MB Cache, 400MHz FSB)
512M (2 pcs)
DVD/CD-RW Combo
8 cell battery
80G HDD
WinXP Home
Bundle with Norton Internet Security (I have to buy something to avoid delivery charges)
1 Year Warranty
Wifi a/b/g
SD slot

Pros:

Cheap (I can not found similar deal from other brand)

dvd/cd-rw built-in, no need to carry arround docking or external drive

Cons:

keyboard is not full size (, . / is smaller than others) and Fn key for page-up page-down.

Guide to install Debian on it: here and here

Conclusion: No regret, cheap and great.

DLINK DI-624+ Intermittent Loss Connection Problems

2005-05-26T23:58:00.000+08:00

Lesson learn when upgrading DI-624+ firmware:

upgrade will delete all existing settings
DWL-2000AP+ (client mode) able to connect to DI-624+ only when DI-624+ broadcast it's SSID

It has been 4 days since the upgrade, and there is no connection problem so far. I think the upgrade fixed DI-624+ Intermittent loss connection problem.
