That's because the numbers from Compete do not correspond to reality. Compete.com is tracking some preselected panel of people, which in no way could represent the entire site usage. And then they stretch and inflate that data, and call it the "site profile".
I absolutely agree. It feels like an elaborate thought experiment carried out for the sake of experiment, and artificially handicapped by many limitations to the boot. I'm surprised a more sane thing wasn't proposed at the time.
In fact once someone has one of your Bitcoin addresses, they'll be able to see and track all transactions involving that address, including "shuffling" into new addresses. One can even construct a whole graph of transactions starting from some known bitcoin address since the chains of transactions are absolutely transparent for everyone. I guess it's a dream come true for the intelligence and data mining agencies.
And yes, the only way to opt out of that transparency is to use the laundry and mixing services - the chain of transactions ends once you put your sum into the service and retrieve them back - since you (most probably) will get other people's coins. Just be careful not to put too much since you may get back your own coins. Also, such mixing service may not be free.
So the article says 1MW, the author's video shows 1MW, and the youtube page says "it fires an intense 1 MW blast of invisible infrared 1064nm light". And yet a single anonymous comment saying 1kW is more trustworthy.
How's that "News for nerds"? We have many more outfits that are more suited for political news like this. I'm tired of all this recent creep of political garbage over/.
Banker is from Brazil and evidence was seized there. Why FBI was involved? It is not their jurisdiction and they are not encryption experts. Maybe those journalists should learn something about NSA before writing "article" about failed decryption.
Yes, I never understood why so many pay attention to Joel's inflammatory rants.
I don't even want to start on his company's product (Fogbugz). Seriously, ASP/VBScript translated to PHP? And then inventing a new programming language just for a web app with ability to output in several other languages? Ugh.
Sounds familiar: http://seoblackhat.com/2009/07/10/link-pyramids/ By the way, if blackhat SEO's describe this technique in the open, it's either already well known, or its effectiveness has been diminished to the point where hiding the details isn't worth it.
Do you know the cost (salary or consulting) of a MySQL expert? How about the cost of optimizing for that one database, tying yourself down to it with non-standard SQL?
But now they are optimizing for another, even less standard database (Cassandra), tying themselves down to it with non-standard query syntax. What was your point again?
Hardware is generally cheaper than developers -- especially the really rare MySQL wizard that groks the SELECT procedure deeply enough to be able to rewrite them to use fewer disk seeks.
The thing is, the stuff they missed in their SQL queries doesn't even need a MySQL wizard in blue cape to grok. There were no JOINs, no subselects, nothing high SQL magic at all - an average self-taught DBA would spot the suboptimal index usage. They should have totally solved it themselves.
I was just casually browsing this article because I don't know much about DBs, but if you tell me that there's a problem that can be solved by throwing more hardware at the problem or hiring a very skilled optimizing DBA, I would take hardware 19 times out of 20. I'm not disputing the software solution is technically feasible, just that it seems like a risky bet.
The funny thing is that they still can't skip "a very skilled optimizing DBA" step even with the NoSQL solution. They still need a database architect, and they still need to optimize their queries. But this time, finding a good DBA would be much harder since I imagine the number of NoSQL specialists (and in them the number of experts specializing in Cassandra) must be much lower than the number of good MySQL DBAs.
Of course, now that they have a system that supposedly scales with a simple addition of new hardware to the farm, they may get away from optimization for some time - if their DB architecture is good.
So you are right about the NoSQL fashion trend. Looks like for some companies it's easier to throw a pile of cheap commodity hardware driven by some NoSQL BigTable-wannabie at the problem instead of carefully optimizing queries and indexes for the best performance.
But Facebook's PHP is also a webserver, as evident even from this story headline. Hence the question is valid. I'm too wondering how nginx + PHP/FastCGI compares to HipHop as a webserver.

It's not a holiday in a sense that the whole country has a day off. It's just an official nifty name for this particular day. Also a good occasion to praise the work of your friendly programmer in the next cubicle.

Now your turn, eager to hear your "rumors in certain circles".
I have a vague recollection they are now sharing some USA citizens' account information with USA.

For the reference, here's another such Google+ profile, from Alexa, which shows no "dramatic growth" whatsoever:

While demos from that era looked nice, they had the problem of not having to worry about AI, an interface, asynchronous audio and video...

The MIT report cited in the "article" is from 1972. Enough said.
And in his Robots and Empire, the Earth is special because of the relative abundance of the radioactive elements like uranium in the Earth crust.
Hear, hear!

This article discusses transparency and anonymity issues well:

I wish I had the mod points to vote for that comment.
Check his other comments and submissions, he appears to be on a mission.

Steve, is that you?..
It's more like "Gattaca". But you are right, the ups and downs were already considered in the movies, with the emphasis on downs.

As several MySQL experts already noted, Digg isn't even using the indexes that provide maximum performance in the query that they present as problematic for MySQL:
