Linksys WRT54GP2 Router with ATA

Thursday, May 26th, 2005

I seldom get a toy like this, so I’m very excited!

Linksys WRT54GP2 with ATA

This is essentially a combination of the WRT54G wireless router and a Sipura 2000. I get to play with this because I had signed up to be a beta tester with engin, with whom I am contracting.

Incidentally, the announcement came today that engin had won the AIIA 2005 award for communications applications. I can’t help but feel proud, though I haven’t been around long enough to claim any credits for it. Congratulations, and kudo’s to all my colleagues.

Time Zones

Sunday, May 8th, 2005

I was confused by the astrological chart generated for me by astro.com, which says that my birth place (Kuala Lumpur) was in the GMT+7:30 time zone. That totally defies my knowledge about time zones. For me, Malaysia and Singapore are in GMT+8:00. Period. We have no Daylight Saving Time, so no complications there.

First thing I did was to do a binary search on astro.com’s atlas query tool, and found that astro.com thinks that on May 1st, 1982, Kuala Lumpur transitioned from +7:30 to +8:00.

So, I did a bit of research and learnt something. I stumbled upon Helmer Aslaksen’s page, which contains very extensive explanation of the history of the time zone and its influences in our region. It turns out that astro.com was right – at the time of my birth, Malaysia was observing +7:30. Now I feel really stupid.

I then remembered that the entire timezones(tz) database is on any UNIX system with glibc installed. To view information about your location, look for the appropriate geographical location under /usr/share/zoneinfo and use ‘zdump -v’ to view the complete history of transitions in your location. For example, to see Singapore’s time zone history:

$ zdump -v Asia/Singapore

Asia/Singapore  Sun Aug  8 16:30:00 1965 UTC = Mon Aug  9 00:00:00 1965 SGT isdst=0 gmtoff=27000
Asia/Singapore  Thu Dec 31 16:29:59 1981 UTC = Thu Dec 31 23:59:59 1981 SGT isdst=0 gmtoff=27000
Asia/Singapore  Thu Dec 31 16:30:00 1981 UTC = Fri Jan  1 00:30:00 1982 SGT isdst=0 gmtoff=28800
Asia/Singapore  Mon Jan 18 03:14:07 2038 UTC = Mon Jan 18 11:14:07 2038 SGT isdst=0 gmtoff=28800
Asia/Singapore  Tue Jan 19 03:14:07 2038 UTC = Tue Jan 19 11:14:07 2038 SGT isdst=0 gmtoff=28800

Notice the cut-off at the end of 1981, when Singapore shifted to GMT+8:00. I can’t seem to find any information on who is right – the tz database or astro.com? Obviously, the tz database thinks that the transition from +7:30 to +8:00 was at Dec 31 16:30:00 1981 UTC.

Does your Windows box have this? (Use the time zone converter if you can’t get your hands on zdump, though you would have to perform a more superior algorithm than binary search to find out the transitions from this tool.)

More Burnt Food

Saturday, May 7th, 2005

What’s with me and burning the food I cook? First, it was the Kebab, now it’s the Sargent’s pie:

Burnt Pie

The thing I don’t understand is, how come the branded part is unaffected?
