Slipstreaming Windows/Office with service packs - 9:42 am
Geez...Windows got more bugs than those in my backyard
Computing , Guides - DaRen
I just re-install (again) my windows on the weekend. I borrowed Roxio Creator CD (a burning software) from friend, install it, reboot windows, and realized my windows are screwed up. Windows are running extremely slow, many of the windows services are not running. I gave up... even the System Restore is unable to load up. This is the 2nd time in 2 weeks time I need to reinstall windows on my notebook.
So, it's backup time. Not much things (rubbish) to backup since this is still a pretty "fresh" copy of windows. But hey, the Copy & Paste, Drag & Drop, CTRL+C & CTRL+V ain't working  ... Luckily the command prompt is still working, the good old copy and xcopy command saved the day =)
After going through the pain of windows update to get SP1 upgraded to SP2, I think it's a good idea to Slipstreaming Windows XP with Service Pack 2 (SP2) to save myself some time in future. On top of that, you can Slipstreaming Microsfot Office (2003) with SP2 (or any version of Office you have)
However, you still need to do windows/office update after installation to get HotFixes and optional updates. You can "slipstreaming" HotFixes too, but it's way too complicated, you can search Microsoft's KnowledgeBase for more info or just leave the hard work to Windows Update =)
DNS Propagation - 7:17 pm
uh, my windows is caching the DNS records too!
Computing , Internet , Site Issue , Web Hosting - DaRen
Rawwwrrrrrrrr ~~~~~~~ !! This site is finally up and running again
beh tong nia... I can't believe my lame ISP really took 72hrs to update their cache for DNS records ! Last week, my webhosting company actually planned to do some RAM upgrades for the server. Then in the middle, I'm sort of confused, but I think they moved some of the accounts to another new server/datacenter in US. So new server means new IP address. That also means http://ahkuan.com is pointing to another new IP address. The changes is made effective pretty quick in the top registration database and the webhosting's DNS servers, however, the so called DNS propagation process is causing all the mess around.
Let's go in plain english... You see, every ISP cache the master DNS records and read them locally instead of looking them up on the Internet each time someone wants to view a website. Some ISP fetch a new copy once every 24 hrs. However, some ISP (like the one that I'm using) they fetch a new copy once every 72 hrs... or even longer ! So even though the domain name ahkuan.com is already mapped to a new IP address in the top level domain servers, but your ISP's DNS cache is still pointing to the old IP address ! So there will be chaos... some will be viewing the most updated content on the new server but some will still be visiting the old content on old server. Unless everybody is using pure IP address xxx.xxx.xxx.xxx instead of ahkuan.com, you'll probably have to wait up to 72hrs until your ISP refresh their DNS records cache.
It won't be surprised if you're still having problem to resolve to the correct address even after your ISP updated the cache. The problem might be your operating system is caching its own copy of DNS records. For windows user, go to command prompt, and type the following command:
This will flushes and resets the contents of the DNS client resolver cache. Try /displaydns to display the cache content.

Another Dell notebook on fire - 2:53 pm
Model: Latitude C600 (oh well, 2nd hand)
Computing , Hardware , News - DaRen
 Dell notebook with battery problem Another alert message to all Dell notebook users out there: A family from Leicestershire in England was left in shock after their Dell laptop exploded "like fireworks" and set fire to their carpet and lounge.
According to a story in the Leicester Mercury, Shaun Allen, 39, said the drama experienced by him, his wife and children. The offending laptop was a Dell Latitude C600 bought from a shop in Coventry, about a year before for about £500.
Quote:
"There are six batteries inside a compartment, and they were shooting out like fireworks, like rockets. "
"They even bounced off the ceiling, they went up that high."
"I tried to extinguish the laptop and cover it over with a towel. I tried to carry it outside, but it was still exploding and I let go of it."
"As I dropped it, more batteries came out like fireworks. A couple of them hit the ceiling then bounced on the floor. Another one hit the ceiling and set fire to the carpet. My wife was jumping on it to put it out."
An investigator examined the Allens' laptop.
A Dell spokesman said that although they believed the battery which exploded was not the original supplied by Dell, the company was supplying a new laptop as a gesture of goodwill for the family's co-operation with the investigation.
Last month, Dell formally requested 4.1m customers around the world return batteries shipped with its notebooks sold between 1 April 2004 and 18 July 2006. The recalled lithium-ion batteries were made by Sony, saying that Dell branded batteries with cells manufactured by Sony could, under rare conditions, overheat
After reading this, should I just remove my battery from notebook? I run it on AC power 24/7 and the weather is starting to turn warm now... This worried me because I'm using a Latitude C640 purchased on 2003, although it does not falls under the time period for recall. I really don't wan't fireworks going on in my room, or even got hit by fireworks...also, did I forgot to mention I got 2 batteries... ? OMG ~~~ !

PC turns 25, Happy Birthday ! - 10:54 am
Computing , Gaming , News , Tech n Science - DaRen
 A release photo of the original IBM PC Computer firm IBM made technological history on 12 August 1981 with the announcement of a personal computer - the IBM 5150. Although IBM is not the first that came out with PC or the term "Personal Computer", however the IBM 5150 is the first that successfully gained wide acceptance and this led to global impact on PCs. It's recognised as the ancestor of the modern PC, a crucial step in computers' evolution from expensive geek's play toy to business and home computing. After all these years, PC has significantly changed our lives.
Quote:
Roughly one billion PCs are now in use across the world; many office workers spend more time with their PCs than they do asleep or with their families. But the PC's spread has been uneven: in America there are 70 PCs for every 100 people, compared with 35 in France, 7 in Brazil, and 3 in China.
IBM 5150 came in 3 versions, they cost between $1,565, for a home model, and $4,500, for a machine designed for the office. The $1,565 IMB 5150 had a 4.7Mhz processor, 16K of memory and it comes with keyboard. Disk drives were an optional extra but each 5.25inch disk could hold 160K of data. It included Microsoft's BASIC programming language. The machines could display four different colours of graphics and 24 different colours for text. It also included a built-in mono speaker for music and audio.
 Dig Dug What ?! 4.7Mhz and 16k of memory ?! Most of the terms & conditions, license agreements these days are more than 16k even in pure text, on top of that, a click on "Start" on Windows will certainly crashed the 4.7Mhz processor... hehe...
I still remember the days of playing Dig Dug when I'm a kid ~12 years back, I can't remember what kind of PC is that, but the green console text reminds me of Matrix, and we uses 5.25inch disk to load the game. Then I came across a more modern PC, playing Mortal Combat in friend's house. The first game that I ever played on my Pentium 600Mhz desktop was Command & Conquer in DOS mode (greetings to all C&C fans out there). Loved the Lemmings game too back that time. Those little tiny lemmings with green hair with faces that's not visible... they're all nice nostalgia of mine. Again, if you wonder, the game is in DOS mode as well. Hmm, Doom was fun that time but now my Windows XP can't run Doom 1 and I don't even bother to try playing Doom 3 on my notebook, I don't want my notebook to overheat and catch fire.
Anyway, the cheapest model that used to cost $1,565 would cost around $3,500 today (in 2006 figures), taking 25 years of adjustments in the retail price index into account. That's around $AUD 4,500. What can you do with $AUD 4.5k ? Oh boy, you'll pretty spoiled if you have that much of money to spend on a dekstop PC today. Other than high ends computers, you'll probably looking at buying a small server, get a dedicated line and start hosting service... ^^
Salute to those great people who dedicated their time and bringing this great technology to human. Thanks !
Enable mod_rewrite in Windows - 7:21 pm
Apache's module - mod_rewrite
Computing , Guides - DaRen
A quick tip to enable Apache's module, mod_rewrite, for Windows. You need the extra step 4 & 5 if you're still unable to enable the mod_rewrite in Windows.
- Find the httpd.conf file (usually you will find it in a folder called conf, config or something along those lines)
- Inside the httpd.conf file uncomment the line LoadModule rewrite_module modules/mod_rewrite.so (remove the pound '#' sign from in front of the line)
- Also find the line ClearModuleList is uncommented then find and make sure that the line AddModule mod_rewrite.c is not commented out.
- Then, find the the below section in httpd.conf
DocumentRoot "C:/www/public_html"
#
# Each directory to which Apache has access, can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
#
# First, we configure the "default" to be a very restrictive set of
# permissions.
#
- Now modify the option for AllowOverride to look like this:
<Directory />
Options All
AllowOverride All
</Directory>
Note:
The AllowOverride None in <Directory "C:/www/public_html" > scope will still disable url rewrite even though you got AllowOverride All in the scope of <Directory />. So be sure to check the AllowOverride options for every directory scope.
It's always convenient to use Options All but not a so-good-idea for stricter security. See Apache 2.0 directives for more info.
ps: Just to say "Woohoo ~~" for my weblog to hit over 100 entries =)
Linux filesystem and permissions - 7:50 pm
Owner ? Group ? Who owns who ?
Computing , Security , Site Issue , Web Hosting - DaRen
I'm still having trouble with my new hosting environment. They're using different configuration in some areas and taking me time to do Q&A between me and the support team.
For example, in my new hosting environment, PHP is run under the ownership of "Nobody". That means the folders/files created using PHP script has the group 'Nobody' and owner 'Nobody' in Linux filesystem. That doesn't hurt but it's a pain in the ass when it comes to file manipulation through FTP client. That's because when you login through FTP, you belongs to your username group. Thus making you having no rights to manipulate to those files that are create by PHP script. Sounds stupid eh ? (See here)
But that's not the end of the story. If you upload/create the files through FTP, you can't delete them through PHP script because of the owner/group permission issue! That's really stupid but then the answer/solution I got from the support team is
Quote:You have to first connect to the FTP server from the PHP code in the script . Then with the php script you can create the file/folder. So when you are connected to ftp server and then the file/folder is created then the file/folder has the ownership of the ftp user that you have used in the script. So you will be able to delete this file created from the FTP client.
*Fainted... ... ... ... ... ...*
I suggest them to use suexec or suPHP but I doubt they will ever care about that. Any Linux guru can help me ?
Dell XPS 600 Renegade - 11:59 pm

Been looking at this over and over lately... Dell's XPS 600 Renegade !
However I don't think I'll buy Dell's desktop because it's costing too much if Im getting that XPS 600 Renegade customized. Still prefer to go to cheap but realiable computer shops to get the components.. although the service might not be that good compared to Dell.
Dell is taking gaming seriously as the potential of gaming market is great.
Still have no idea what's a Dell XPS 600 Renegade ?
Hello ?! Quad NVIDIA SLI Technology... you know what that means ?

Mozilla Editor - 4:09 pm
Browser , Computing , Internet , Standards , Website Intro - DaRen
via woeisiong:
It seems that Mozilla is building it's own editor. I suppose that's a WYSIWYG (What You See Is What You Get) web-based editor.
Quote:The Mozilla editor provides HTML and plain text editing functionality in Gecko-based applications.
This is a good thing to FireFox and other gecko-based browser... BUT, what about IE and Opera ?? They aren't gecko-based. Does that means that they will not be able to use it ?? hmm ??
I've seen a few WYSIWYG but most of them are pretty buggy. They all consist of "complicated and sophisticated" things (codes, lol) in it, but they have the problems of cross-browser-compatibility.
Anyway, aren't those WYSIWYG editor and BBCode tags exists solely for one purpose ? To make lazy people's life easier =)
Visit the Mozilla Editor and the live demo (Note: I got a feeling the demo page is out-dated).
