Wow. Has anyone heard about buffered writes ? And does kernel-level page cache ring a bell ? No fsync was ever used in the benchmarks, therefore, it is never actually hitting the disk. The only good thing about this paper is that the Java and Python listings are available at the end, for everyone to identify the basic flaws in this research.

So yeah, it's faster to write directly to MEMORY than to do a copy before writing to MEMORY.

I thought hydroelectricity was not considered clean by the USA, creating a weird situation with Quebec's overproduction exports (among others maybe)...

What's wrong with you? Why the hostility? I even said "I doubt they are getting any discount here, but it is possible". I did not claim to know the details of his arrangement with ETECSA, why are you assuming I know? It is a fact that some government institutions pay in CUP, and Kcho's account with ETECSA is by no means normal (for starters, ETECSA doesn't sell ADSL, or any kind of connection for that matter, to Cubans, and it doesn't allow wifi without tons of paperwork and oversight). Without knowing details of his contract with ETECSA (which I suspect you may know, if you are who I think you are), I can't state anything different than that. It is possible, but unlikely. The situation is already very atypical as it is.

Also, if you have more information, like where is this hotspot, please share. I haven't been able to find that information anywhere and it would be very useful to know.

By that token, that applies to every country on earth. Believe what you will. I come from a family of doctors---Cuban doctors---including, what a coincidence, a neurosurgeon and an oncologist, and I can say from experience that the answer to the question asked is a resolute "yes". Of course, that is anecdotal "evidence" and not hard data, but I didn't see you provide any data either.

Yes.

That said, the actual price Kcho or the artist association is paying has not been disclosed. If the artist association is footing the bill (either directly or as a proxy for Kcho), it may be significantly cheaper than $900. The rates in those tables are "public" rates, but government institutions often get significant discounts, such as being charged partially in CUP instead of CUC (that would be up to 25 times cheaper). I doubt they are getting any discount here, but it is possible.

Here. Look under the header "ADSL". ETECSA charges $890/month for a 2048/256 Kbps link. The article implies that Kcho is paying for that out of pocket. The hotspot is free for the users. Another article I read about it gave me the impression that the artist association could be footing the cost. In either case, the $900 refer to the price of the ADSL link.

$4.50/hour is the price the governent charges in the public internet cafes, not the price at this new hotspot. This hotspot is free. That is the news here, this is the first internet hotspot that is free and open to the public. This is not clear from the article or the summary. Both mention the official cost and that Kcho decided to make it free, but they don't mention whether he succeeded in making it free. He did.

Kcho, whoever he is, is covering the outrageous cost of ADSL. I wonder if there is something we can do to help him.

Those who did specialize in computer science early on, after high school let's say, tend to not understand physics / chemistry / biology / etc. as well, and it shows.

That doesn't mean they are anti-science / anti-global-warming or anything like that, just that the rest depends more on ambiant politic than critical use of scientific knowledge when shown scientific studies...

Well, given that Cubans can leave Cuba, I don't see your point.

We've moved from displaying remote applications from the xlib level over ssh, to the toolkit level over ssh (as parent described). It's Unix moving forward, finally.

Microsoft's proprietary RDP protocol or alternatives such as VNC work differently (and usually pretty slow, since they work similarly to xlib, passing compressed bitmap images over the wire). If you want a remote desktop and your network link is fast enough, that's fine, but for most cases, toolkit-over-ssh is more secure and efficient.

What they really want is white box cryptography, but it seems computationally impractical right now.

Also, http://en.wikipedia.org/wiki/T... did this and was broken!
