What's funny is that there is actually people who think like that. Apparently if we just sit around and wait, things will get better. I call this the dark side of the "invisible hand" of the market.. because it is invisible, people forget how it comes about. In order to get improvement in technology you need a market for that technology. And, typically, you need some loss-leader to create the market in the first place. Government funding serves this purpose well.

The sad thing is that this seems to be pretty much par for the course. If only we wait just a little while and skip all those annoying intermediate steps, we will soon have fantastically good rockets / fusion reactors / whatever else without having to pay anything...

Actually, losing weight has little to do with exercise. You exercise to be healthy, you eat fewer calories than you burn to lose weight.

What have geeks come to these days... Ok, in your own words, you eat fewer calories than you burn to lose weight. To lose weight, you can therefore do one of the following three things:

1. Eat fewer calories.

2. BURN MORE CALORIES.

3. All of the above.

The item under number 2, "burn more calories", is best achieved using exercise. Why you state that losing weight has little to do with exercise, and get modded informative for your efforts, is beyond me...

I'm hardly morbidly obese, but I do struggle to keep my weight down. Maybe that means I'll live ten years less than my peers - I'm willing to accept that. I do try to control my diet, but the fact is that unless somebody comes out with some kind of medical advance I'm not going to be average in weight without a huge amount of effort. I'm not sure that effort is really worth it - I'd rather die happy at 70 than suffer until 80. :) And if somebody comes up with better healthy ways to lose weight that don't involve huge amounts of self-deprivation, then that is just a win-win for everybody.

You know, as long as you think of it as suffering, you won't lose weight. Why not think of it as investing in yourself?

Occasionally I have these late-night eating-urges. I find that by ignoring them for ten minutes, and just focusing on something else, they go away. I'm sure that if I sat down and started feeling incredibly sorry for myself for allowing my poor body to starve, I'd be eating a lot more.

The other thing I do, and I find helps really well, is making sure my house is not stocked with snacks in the first place. If I wanted to snack _right now_, I would have to go to the supermarket to buy snacks first. Typically that barrier is enough to stop me from doing it. I do keep fruit around the house though - if the feeling of hunger has not gone away after ten minutes I eat an apple or a banana or something like that.

I've read this whole discussion so far... Including the summary and article that come at the top. Unfortunately, while it mentions that the majority of deaths were obese people, there is nothing to indicate the extra risk that obese people run: is it only a marginally greater risk of death, or do they all die?

In your case, I sincerely wish you best of luck if and when the flu becomes a global pandemic. You probably still have a couple of months to try to lose some weight to prepare - because despite your words, you have a significant chance of losing weight if you want to. On the other hand, you probably don't have much chance of avoiding the swine flu when it really starts. We'll see if you are still posting come spring.

Sure, and taking someones picture will steal their soul as well. And now you can get a camera and a GPS in a single convenient package, so you can both take the souls of the natives _and_ conveniently avoid their local culture at the same time!

Meanwhile, back on planet Earth, my GPS has brought me to more interesting places than I care to count, places I would never have visited without this handy tool pointing the way (or at least helping not to get lost). I'm sure the next generation won't even know what the phrase "getting lost" really means, just as being "out of contact" will have no meaning to them. A map will be about as useful to them as a sextant is to us (what? You sold yours on Ebay years ago? Shameful!). And personally, I wish them all the best with it!

Comment Re:Hear the heads exploding - Java is fastest (Score 2, Informative) 62

Okay so the fastest engine is using Lucerne, a Java search engine, and this is neither tuned nor horizontally scaled (which it can do very well).

C++ and C both fail to deliver the same level of performance as the Java virtual machine.

Oh wait hang on... does this mean that for complex applications the most important performance piece is normally actually the efficiency of the code rather than the efficiency of the base platform and therefore having a language in which it is easier to write efficient code is better than just having the one that is fastest to execute a for loop?

But hell this is Slashdot and Java is Slooooooow...

Actually if you check here, you will find that an implementation of the exact same Lucene done in C++ is about three times faster than Java.

Sorry for spoiling your moment there...

Nothing else to say, really

Really? Am I the only person that found it interesting that Lucene, the only non C/C++ implementation, gave some pretty impressive stats? I mean, it's written in Java and although it has a slower index time its search time, index size and relevancy are impressive.
 

Yes, that's pretty much you yes. Different algorithms, therefore different performance. Reimplement Lucene in C++, then see what the differences are in terms of speed (and if you care, code size, complexity, etc.). Until then the comparison is totally meaningless.

And gee, what's with the defensive attitude...
