Chernobyl disaster - 20 years back

yeah major fuckup by the russians!

"On Saturday April 26, 1986, at 1:23:58 a.m. local time, unit 4 reactor, known as Chernobyl-4, suffered a catastrophic steam explosion that resulted in a fire, a series of additional explosions, and a nuclear meltdown."



The World Health Organisation (WHO) has estimated that the total radioactivity from Chernobyl was 200 times that of the combined releases from the atomic bombs dropped on Hiroshima and Nagasaki.

Bush: government research developed iPod

"
During a speech at Tuskegee University, President (and iPod user) George W. Bush told his audience, “the government funded research in microdrive storage, electrochemistry and signal compression. They did so for one reason: It turned out that those were the key ingredients for the development of the iPod.”

if the us govt contracted microsoft….
- there would be a new copy-cat version of a sony or apple mp3 player every year…
- with service packs every three month…
- a pseudo fire-wall…
- a beta-version of windows media player!
- copied and relabeled open standard media types which would run only on their mp3 player
- every time you add a song to it… it’ll run a virus scan…

"Do not believe,
in what you have heard,
in tradition,
because it is handed down to you from generations past,
in that which is spoken and rumoured of by many,
or simply because it is found in your religious scripture
or has been told unto you on the authority of your teachers and elders.

only when you yourselves know after watchful thought,
that these things are pure, blameless, agree with reason
and leads to benefit, and happiness of one and all,
enter on and abide in them."

Gauthama Buddha, The Kalama Sutta, Anguttara Nikaya, Vol 1, 188-193




From Wikipedia, the free encyclopedia

The Kalama Sutta (Sanskrit: Kalama Sutra) is a Buddhist sutta in the Anguttara Nikaya of the Tipitaka. In this sutta, Gautama Buddha instructs the people of Kesaputta the Kalamas on which basis one should decide which religious teaching to accept as true. The Buddha tells the Kalamas to not just believe religious teachings because they are claimed to be true by various sources or through the application of various methods and techniques. Even Buddha's own teachings are not to be accepted at face value.

The Buddha provides ten specific sources which should not be used to accept a certain teaching as true, without further verification:
1. Oral history
2. Traditional practices
3. News sources
4. Scriptures or other official texts
5. Logical reasoning
6. Philosophical reasoning
7. Common sense
8. One's own opinions
9. Authorities or experts
10. One's own teacher

Instead, he says, only when one has personally verified that a certain teaching is skillful, blameless, praiseworthy, and conducive to happiness, then one should accept it as true and practise it.

However, it should be stressed that the Buddha instructed the Kalamas to pay attention to the teachings of the wise; he did not advocate that individuals can or should decide truth purely by and for themselves. Nevertheless, the emphasis remains on one's personal verification of any teaching, and in particular whether a particular teaching reduces or eliminates the mental defilements of greed, hate and ignorance, or vice versa (in which case it should be rejected).

time (to) change?

this has nothing to do with lorentz transformation or time dilation... you know the whole "time is relative" thing....

sri lanka is back to +0530 UTC time zone - which sux....

and... dont be surprised... there will be a few random power cuts in the evening...

the official government press release

another govt press release
The Director General of Meteorology gets a say in this... his dept has all the meters and gauges so he gets a say in this
(Meteorology is the scientific study of the atmosphere that focuses on weather processes and forecasting)

the rationale behind the time shift in 1996 was to save power... 'cos it saves a considerable amount off the peak electrical power demand....

have a look at this CEB report done on a commercial building in colombo... according to that... lighting amounts to 15% of the peak electrical demand

work ends around 5pm... and according to the old +0600 UTC time zone - solar time would be around 1630... sunset would be around 1800... there is 90 min of valuable sunlight available...

with the +0530 UTC time zone - there will be just 60 min of sunlight from from 5pm till sunset! which means that there would be an additional 30 min of increased lighting... which amounts to a massive amount of electrical energy utilized for lighting during that 30 min... hmmm... and sri lanka has like a power crisis... 15% rate of electrification with a maximum demand close to 2 GW... so we need to add like 300MW to the grid every year... well at least 150MW without exaggeration!!!

read this bbc article
" Some of the country's Buddhist clergy are rejoicing at the prospect of a change because they say Sri Lanka's "old" time fitted better with their rituals."
