Microsoft were doing shared-nothing clustering on SQL Server LONG before MySQL types had even coined the word sharding to mean the same thing... Microsoft are heavily invested in SQL Server, so they are biased against MapReduce.

They are different beasts really. It'd be hard to implement something complex, like the PageRank algorithm, in SQL. On the other hand, MapReduce is not designed for tasks such as "SELECT * FROM table WHERE field > 5", which is one of th

You are right in theory. In practice there are already tons of Twitter usernames squatted, and Twitter is not doing anything to manage those. The monetization of user names would only make the practice more popular.

Great! That would just cause a flood of bulk Twitter name registrations.

That's great for creating custom notification sounds for your app.

With all the DiggBar talk I'm surprised no one mentioned Facebook, which does exactly the same when you post a link on your news feed.

About a week ago there were 1.4 billion tweets and 27 million registered users, based on the tweet and user IDs. If anything, that number is slightly more than the real thing, because of deleted tweets and spam. I multiplied the tweets by 2

A quick calculation shows that all of Twitter's tweets come to about 260GB uncompressed (including 40 bytes of metadata for each tweet). The social graph would be about another 200GB. Given that the entire Twitter could fit on a high end la

I guess the real questions is are SSDs good enough to replace data that now sits in RAM? For example, Google keeps their entire search index in RAM. Would they be better off keeping it in SSDs?

Anyone else find it funny that this post coincides with COBOL's 50-year birthday? It's a good PR move, though. By showing that mainframes work for Web 2.0 (even with a faulty argument) they'll probably score a corporate sale or two.

If it's such a big industry how come no one has written something that translates COBOL to a modern language?

Summary: Twitter changed their API, we didn't check properly for duplicate tweets and screwed up our database.

Every cloud computing service let you run your choice of Linux and has an API. It would be trivial to write a library that talks to all APIs. What's the problem? (I'm not including Google AppEngine, because despite their branding, their cur

Agreed, it is not the same, but I'm saying if I needed to resolve a shortened URL, I would do it myself instead of sending an HTTP request to you so that you can send an HTTP request on my behalf. At any rate, using your service would be s

http://php.net/strtotime/ I don't mean to be a troll, but the fact that a simple function that has been available in other languages for years is only now making it to CL is a red flag for people considering learning Lisp.

Summary: 1992 usenet message from the creator of Minix, explaining that Linux is no good because it's monolithic and closely tied to x86. In fairness, Linux evolved so that it's no longer x86-specific, and insmod makes it somewhat non-monol

As part of my college job I had to administer a small Blackboard installation. For one, it did not allow upgrading the Windows server it ran on before the Blackboard code had been adapted for each new Microsoft patch. It was a pain.

Great, except that it's no good for small jobs. Looks like if you want to run a 10-minute job you are charged for a full hour for each instance.

It's quite possible that they got Gigabyte to do a custom design for them, given their volumes. Or, the 5v conversion is done in an extra device between the power supply and the mother board power socket (ATX or whatever it is).

I for one am surprised that those are 2U servers and they haven't gone to 1U to double their space efficiency.
