The same fragmentation exists for their conferences. Say, you're convinced that none of the established, reputable data mining conferences have a satisfactory number of hype words in their title, or possibly you couldn't get your paper accepted, and it's time to go to a conference on Big Data instead. Luckily, IEEE has you covered: this year you can attend the IEEE International Conference on Big Data Science and Engineering (BDSE 2014), the IEEE International Congress on Big Data (BigData 2014), and the IEEE International Conference on Big Data (IEEE BigData 2014). In any case, if you expect to meet colleagues at "this year's IEEE conference on Big Data", you better check they're actually going to the same city.
Edsger W. Dijkstra : first ALGOL 60 compiler (with Jaap Zonneveld), the THE operating system, correctness proofs, saving us from unstructured code,... Peter Naur: ALGOL 60 language definition
"Program testing can be used very effectively to show the _presence_ of bugs, but is hopelessly inadequate for showing their _absence_." (an overhead slide by Dijkstra, quoted in The Dawn of Software Engineering, 2012)
LHC pumps 9000 m^3 to ~10^-9 atm to insulate their cryomagnets. That's the volume of a 2.4 km stretch of the passenger-only hyper-loop, at a million times deeper vacuum. Now, that they're doing that at CERN doesn't mean in any way it's easy or cheap. And the hyper-loop is still a volume a few hundreds of times bigger, without any compartmentalization.
Thermal expansion is also interesting. Back-of-the-envelope: 1.5*10-5 (thermal expansion coef stainless steel) * 40K (guesstimate max delta-T day/night) * 563*10^3m = 338m thermal expansion/contraction, or 169m at each end. They'll want to insulate it or at least shield it from direct sunlight -- which the solar panels will partially do.
I live in Belgium, and I am required to pay the tax for the radio...
Move to the North.;-) There's no radio nor TV tax in the Flemish part of the country. Well, not a specific tax anyway, they just pay the public broadcasts from general tax income. Of which there is a lot.
It is basically the same everywhere, let's steal money from people
Right, the motto is: if it moves, tax it. Oh, and did you think about declaring private use of that company laptop in your tax form? That's another ~$100 please... more if it comes with internet access.
Where all the tax money goes? As an illustration: the Parti Socialiste, very powerful in the South, has just decided in the face of evidence that Mr. Daerden is too corrupt to be mayor of a small town... but he can stay as a minister of federal government. Maybe they don't have anyone less corrupt to succeed him. Maybe Happart. Oh, wait...
Large radio stations currently have to pay 2.968% of gross income up to 1.46 euro per head of the population in their broadcast area. Income over that is "taxed" at 1.59%. That tariff includes only FM radio. Anything else, e.g. online streaming, is extra. The rules for small radio stations are somewhat more complicated -- available in Dutch here: http://www.sabam.be/website/data/tariffs/Tarief_webradio.pdf
If we have learned one thing from the.eu sunrise period, it's that relying on trademarks does NOT solve domain name problems.
Companies were started and trademarks were registered in countries where it is cheap to do so, with names like 'a-b-c', just to be able to register domain names like abc.eu.
Sorry, with a helium balloon you're not going to get very high. At most tens of kilometers, and that would require a huge balloon for any sizable payload. You need to get to 35786 km for geosynchronous orbit, so say 20km is hardly a quarter of the distance. Even compared to a low orbit it's not a large percentage, for example the ISS sits at about a low 350km. Furthermore, the proposal for deflation would mean you need energy to isolate all the helium from air only to use it once, so it's not exactly free. (Gradual deflation would be required to let you fly as high as possible with a given balloon volume, since you only need enough helium pressure to keep your balloon from collapsing under the surrounding pressure, which of course decreases the higher you get. Anything more is ballast that prevents you from reaching maximum altitude.)
We are talking about a space elevator here, something that's so far beyond our current capabilities its like Leonardo Da Vinci talking about building an A380. When we have the capability to actually build one of these things, a Eurotunnel or Thalys will be childs play.
A perfect Java distro would maybe drop all the deprecated methods (will Sun ever do that? Java 1.6 is a good opportunity...)
Are you nuts? Do you know how many Java SLOC have been written since JDK 1.0? That code is in production now. Do you want to break it all? Do you think the corporations running these classes, depending on these jars, will be delighted to solve another Y2K problem?
Hint: The prime reason that Windows Vista will undoubtedly sell really well, is that it runs the vast majority of binaries made for Windows XP, 2000, ME, 98 and 95 (and may even 3.x) unmodified, really well, and no other OS on the market does that.
Well... given any fixed (sufficiently complex) formal system, there are true things you can't prove (Gödel), so in a sense you can't explain/understand them, unless you change to another formal system, which will again have other unprovable things.

[...] 274 million ad clicks per month [...] that's $2.74M. Also, don't forget that Google does Cost Per Impressions, or per 1000 ad views. [...] generates another $6.85M/ad displayed.
It's either/or. Either you pay Google for clicks, or you pay for impressions.
[2]. One of products of our company, a HR system, is priced at $600, another one, invoicing+stocks, #330 (Poland, so it's way less than it would be in the US). A glance at Oracle's pricing shows that they start at $5000 for the minimal license. This isn't just "expensive", this is "no business".
That's incorrect, or at least not the whole thruth. First, there's the free Express Edition. Second, Standard Edition One is either $5000 per processor or $150 per user (minimum 5), whichever you choose, which is probably the lowest number. That's list price. If you ship it embedded with your app, you'll pay far less. If you buy lots, you'll also pay quite a bit less per piece. Not that _I_ would consider embedding Oracle in a $600 app unless I was _very_ sure that it would never exceed the limitations of Express...
[3]. If one system needs separate staff for basic operations, and the other just works, which one is better?
I'd agree that PostgreSQL has become quite easy to maintain these days. Autovacuum in particular has been a nice improvement. As for Oracle... sorry, no time to comment on that. Too busy with the Oracle client security updates they recently released...
OTOH, the feature set is still not quite the same. Flashback queries, RAC, feature-complete GUI, etc. (Yes, PostgreSQL has GUIs too, but I've tried most of the free ones, and they are worthless. They crash and burn every five minutes, or generate incorrect SQL, or do not support all data types, or do not generate DDL, or a combination of the above.)
Redhat requires a license for each VM under VMware or Xen
Novell lets you run up to 10 instances of SLES (and maybe their other products too, don't know about them) on the supported hardware without paying one euro extra.
doesn't the process have to be frozen for a full mark-and-sweep?
You can trade CPU cycles on a spare core for much shorter pauzes. Read the docs. However, GC is already quite efficient and typically only takes a small fraction of execution time anyway, plus you lose some efficiency compared to the throughput collector, so hopefully you've got other useful work for that core.
Since you didn't say what kind of server you're building, I'm going to assume: -... - the language is C, C#, or C++, and not Java (process-based servers in Java?)
Standard API package java.nio, serving you since 2002.
Unless you're using Windows, enough DRAM (combined with enough compiler threads) gives you about the same compilation speedup as a hypothetical ultra-fast HDD could give you. That is because the OS can reschedule writes ad libitum. Unlike ACID databases, compilations do not need to issue fsyncs at all.
It seemed that the people who produced the most sweat and breathed the hardest were the most attractive. These features seem to come hand in hand with being overweight but I never really bought the idea that overweight people's blood tasted better. If that were true, all the mosquitoes would have moved to Wisconsin.
If animals would consistently move towards places where food was more tasteful, the human race would long ago have left the US, wouldn't it?
When a specific currency isn't specified on messages in forums such as slashdot, it usually implies either USD or the rough equivalent price in US dollars. In this case the latter since the service was in France.
Come on, so you're saying he took a retail price in Euro, roughly converted it to USD, and came out at USD 29.99?? Sorry, but common sense yells at me that the 29.99 number contains too many nines, so it must be the original retail price, thus in Euro.
If the original poster indeed meant euros despite not mentioning it, then the 29.99 USD would be even cheaper by comparison.
Yes, of course. I certainly hope (but don't think) we'll import the Hong Kong kind of telecom price/performance in Europe soon.
A lot smaller than the impact on the environment of people in third world countries having 12 children per family (especially after a few generations, after exponential growth takes place e.g. in 3 generations: 12^3=1728 vs. 1.3^3=2.197 (approximate average European fertility rate -- children per woman)).
There is no country on the planet with an average of 12 children per family. Not one.
And even if there was, it's numerically incorrect because he doesn't account for only about 1/2 of babies being female.

Well, a volcano 100km away erupted. Crete is still there, I've checked it.

That's not a PC, that's a workstation. It is (was) certainly priced as one.
Not to say that a PC can't do the same. In fact, I have lots of PC's running 24/7 for years, although only infrequently under continuous full load.
