So hairyfeet is pillorying RMS for not being Linus? I think we are all guilty of that. But he makes it sound as if there must be some choice between the two - echos of Bush's "with us or against us". Let Linus be the corporate spokesman in a suit and let RMS be the hairy Prophet. We need both idealists and pragmatists.
Do you want a shot at the title?
Hell no, Linus just wants Linux to be great. He is no evangelist.
Ha, that's one kind of crack that can be fixed. Just replace the screen with plastic like Apple should have done in the first place, if Jobs wasn't so obsessed with form over practicality.
Where on earth is that? Port Arthur? Burkina Faso? It it hard enough to keep up with computer acronyms, so I don't really want to learn all the world's postcodes. Please use English translation in the summary where possible. That also applies to "thru"(sic):-)
We pissed away $3 billion dollars and 13 years of time, when we could have waited...
It's pretty obvious that the ability to sequence the genome in a week could only result from techniques developed and information gathered in the original Human Genome project.
But that doesn't mean you needed to spend $13b! Maybe only $1b was spend on the vital R&D, and the other 12b spent on building the massive parallel infrastructure and processes to implement it full-scale. Plus patent lawyers.
This actually suggests that perhaps we should start transmitting into space
In an infinite universe, our DNA already exists out there. Its just a question of how far. Philosophically, there is nothing to be gained by pumping it out to our possible neighbours. It could only be used against us.
The problem is, since I cook for myself, I cannot be sure about the calorie intake.
If you are geek enough to read/. , it can be done. Get some accurate electronic scales. Dealextreme have a nice 3kg one us$17 posted from HK.
Make a list of joules/g from the 'net of your main ingredients. (Don;t worry about the minor bits). Compare original to cooked portion weight, and you will get a reasonable idea. You may get a surprise about where the calories come from when you add it up. then it becomes a game to cut it down, or cook to a calorie budget.
The key is to manage your servings. If you know you served a decent amount, no excuse for seconds. If you still think you are hungry, fill up on water, then eat some carrots or fruit.
I even make joghurt by myself
German yogurt?
If you can't walk up the hills, you should consider a low-geared mountain bike. It will help.
Good luck.
And remember. The obesity epidemic is related to lifestyle changes in society. If you are still very stressed, take action to change that. BTW, why can't you swim or cycle? I can understand no jogging. Many people find that regular aerobic exercise helps in controlling excess eating.
Slashdot is global. Around where I live, BT means Bankers Trust, and BA is bugger all. Please don't use 2-letter local abbreviations in a global forum, at least not on the first mention in a summary. OK?
would seem to say that the generator is doing 5 times the work to deliver the same real power. Is this an incorrect interpretation?
Fortunately, no. Otherwise we'd be billed for VA. Only the losses are increased. With a pf as bad as 0.2, transmission losses could easily be higher than the power delivered. And yes, a pf of 0.7 means double the transmission loss. So 10% overhead (a common figure) becomes 20%. That is still 400% better than an incandescent.
We are only talking about resistive losses so far. It gets more complicated.
I came across this post
He is only talking about linear circuits. CFLs and switch-mode supplies are not so well behaved.
Simply a bad assumption perhaps. VA is not power. You need to add up the instantanous values, not just multiply two RMS averages. The RMS values are averages, and do not convey enough data to determine load. I did study EE long ago, but the wiki explains it better.
Utter nonsense. Lets consider a trivial example. Attach a large (perfect) capacitor to a generator. That will draw a current, lets say 220V and 1A. So VA is 220. But it doesn't get hot, and the generator feels no load. It burns no extra fuel.
The out-of-phase current does not create a mechanical load, save for small resistive losses, magnetic hysteresis, or other imperfections.
That may be true, but when we talk of efficiency, it is normally based on the fuel consumed, not the peak-production capacity.
Fuel use and CO2 emission depends on real power output, not VA. Even with hydro, you are limited by total energy, not VA. Most hydros can't do peak for very long without draining the dam.
Yes, VA is important, and cabling needs to cope with peak current. But not as important as sustained real power consumption.
If needed, its a simple matter to require better CFL design to improve power factor. But trying to get comparable efficiency from an incandescent is impossible.
Thats a lot of links, but the parent doesn't quite seem to grok what power factor is.
Poor power factor means increased current. A factor of 0.5 doubles your transmission losses, but if they are low enough to start with, it doesn't matter much. Obviously its more of a problem in backward countries that run at lower AC voltage, and so higher current.
Say your network has a 10% overhead (a typical number for residential power.).
Then a 100W incandescent will need 110W at the generator. But a 20W floro with 0.5 power factor will use 24W at the generator (20 + 2 x 10% ). Which one is better?
I'll take my 3G phone, which costs 50c/MB roaming on '3' in italy. Good enough for email, and looking up tourist info. I expect you can get a prepaid SIM in Italy that will cover the whole country for a lot less that 5 euro/day. And if you're in Venice, there are better things to do than reading slashdot all day in some wanky tourist cafe on Piazza San Marco. God, I hope it doesn't have a Starbucks now.
Rabies vaccine is a good example. The infection spreads slowly, so you have time to get a vaccine after infection (animal bite) but before symptoms show. Which is good, because rabies is about the only disease with a higher death-rate than AIDS.
but around here, the roads are black bitumen, so trying to paint them with a laser won't work so well, will it? Except when the roads are wet, then it may work _too_ well. Anyway, we have plenty of real bike lanes here, so I don't care.
Not to mention that green lasers are banned imports. Not sure if this will be a good enough reason on my import permit application.
For every storey on obesity, we get this argument. What I have learned:
BMI is extremely useful for statistics, as it is easily measured consistently, and correlates well to body-fat and health.
The ideal measure is percentage body fat, but that is difficult and expensive.
Waist size is a better measure of health risk, but not so easy to measure consistently, so less good for statistics.
An individual evaluating his own health should measure his waist, and just look in the mirror. On a weigh-loss program, monitor your waist, as its the internal abdominal (visceral) fat thats the big problem.
Yes, you can have a BMI of 30, and not be fat. If your waist is less than 94cm (37") for a man, then great. But its unlikely. Lots of people are strong with good aerobic fitness, but still at risk of heart disease etc from too much body fat.
Maemo Mapper is great, but its just a map program, not a navigator. It can download maps as images from Google maps, Virtual Earth, Yahoo, Openstreet,... It's fantastic when you don't have an internet connection. And it's open-source. You need do download routes from elsewhere.

In short, they require the exact same fuel supply
Sorry, you left out the faulty reasoning leading up that erroneous conclusion, so I cannot correct it. W != VA.
VA is the REAL power...
Utter nonsense. Lets consider a trivial example.
Attach a large (perfect) capacitor to a generator. That will draw a current, lets say 220V and 1A. So VA is 220. But it doesn't get hot, and the generator feels no load. It burns no extra fuel.

Which one is better?
Bulbs can easily (but not as cheaply) be made to last for years,
Oh not that again. Long lasting bulbs are less efficient, so cost far more in electricty than they save in bulb replacement.
If you want long-lasting and efficient, get florescent, LED, HID, etc.
At 5 euro/day ?! Screw that.
I'll take my 3G phone, which costs 50c/MB roaming on '3' in italy. Good enough for email, and looking up tourist info.

Phase 1 human trials will check the safety of the vaccine on HIV positive volunteers
Sensible move. They should tested TGN1412on an AIDs patient first.
Rabies vaccine is a good example.
