If you're question is relatively simple, aimed at the general slashdot crowd, than the answer is that you need to hire someone who knows database implementations

If the question is complex enough for an experienced database implementer, he/she would know where to post that question. And it is not here.

As you can read above. The answer is simple. The problem non-existing for experienced implementers.

Welcome to the 21st century.

Now if you guys could do something about the insationable hunger for credit. You guys already live from the credit of the rest of the world. Sure it stimulates the economy, but in the real world you can only spend a dollar once.

The thicker the crust and the higher the temperature, the more Acrylamide is formed.

One woud think the bright guys at NASA would take this into consideration before exposing their expensive astronauts to this stuff.

Comment: GUI (Score 1) 75

by dr.Flake (#43367111) Attached to: R 3.0.0 Released

Even i have used R in the past for my thesis. My statistician was using S-plus to do magical things that the hospitals SPSS definitely could not do.
However, S-plus was not available to us non-statisticians.
As a complete non-programmer, mediocre statistician, i was able to reproduce en build upon his examples in R.

But what i truly missed was a usable GUI. there were some, and i tried them all at the time, but none were able to do more than the basics. For someone using R daily, a GUI will be more trouble and limited. But for someone like me, a well developed GUI like S-Plus had at the time would have bee more than welcome.

Seeing the headline R 3.0.0, the first thing i was looking for: did they include a GUI by default???

First, i'm Dutch, the northern neighbor of the Belgians, and we like to make jokes of each other.

But why make an island first? One could also transport the energy on shore and do the same trick with an old abandoned mining network for instance. Sounds like the upfront costs are going to be huge.
Also, the North Sea is the most busy shipping route on the planet. Do we really need an extra island in it?

My first thought as well.

Wikipedia's first hit:

"Extraction of a liter of xenon from the atmosphere requires 220 watt-hours of energy.[52] Worldwide production of xenon in 1998 was estimated at 5,000–7,000 m3"

Sounds like we have some scaling issues before this engine puts us on mars on a regular basis.

Supposing this is true, it took this long because everybody thought that dental X-ray was harmless.
(tumor growth in less than 1:4.000.000 images, regardless of the type of tumor.)

Dental X-ray uses less than 0.01 mSv per image.

You absorb 200 times this amount every year, year in, year out. all your life. And if you live in a place with higher background radiation, this number goes up quickly.

So it is hard to prove these tumours are caused by the exams.
Lets wait and see what comes out of this.

Usually these kind of studies have some form of bias thats not adequately corrected for.

Sort of the same for me.

For me the route was also windows -> linux -> OSX.

However, during my linux period i grew accustomed to finding great software doing almost everything i could wish for within a few clicks/google searches.

For OSX its the opposite. For every small task that i want to accomplish, i seem to need to pony up. Every small time programmer tries to make a buck with his little program. Nothing wrong with that, but where are the Free/Libre alternatives?

For now, after long searches i end up installing untrustworthy programs, because i'm used to get it all for "free" (he, i am Dutch). My problem, sure. But a lot of people like me would fall into these kind of traps.

Believe me,

I do not want you to see my "adult projects"

thats something for the privacy of the home, you pervert.

seriously,

what i meant to imply (and you obviously failed to grasp); Slashdot needs to filter away stuff that is far from impressive. If his mirror had had a diameter of 10m, than that would have been newsworthy for a 19-year old. I'm sure younger kids have achieved more impressive results than sticking some glass chips on a 1m metal plate.

also, is 19-years not being an adolescent?

I imagined at least 10x10cm mirrors. Now that would have been "solar power".
