The people I met, particularly at the second interview were pretty remarkable: smart, driven but also friendly and down-to-earth. It was quite intimidating to spend 5 minutes talking to someone and find out they have a PhD in bio-informatics, a masters in computer science and oh, by the way, they fly acrobatics in their spare time.
Still the whole thing was great fun and I came away pretty impressed with the process (and off course the few who got selected at the end).

Unless you validate the image dimensions as well as the file size it may cause problems, for instance when GD is used to try to resize it exhausted the memory limit.

Somehow my PhD supervisor (who was a professor in astrophysics at the city's university) ended up get a consulting gig to calculate whether or not there was any danger of it focusing light and blinding anyone.
He ended up doing a media interview, where he explained that carefully placed shields would protect anyone at ground level from being at the focal point, but then he made an off-hand remark that "it might fry a few pigeons". Of course that turned out to be the only line that got repeated in the ensuing media frenzy[2].
I'm not sure that's what they had in mind when they hired him to consult for them, but we found it pretty funny.

'stty -iexten' fixed it for me on my Mac.

$ echo one
one
$ echo two
two
$ echo three
three
Then up-arrow back to 'echo one'. Then press Ctrl-o instead of enter it will execute the command and display the following one in your history ('echo two' in this case).Very handy for replaying a series of commands.

All the British stations use a satellite link to the British Antarctic Survey headquarters in Cambridge, UK. The link to the Antarctic is transparent to the outside world so all browsing down on the stations (and ships) appears to come from a Cambridge IP address. I'm sure many of the other Antarctic stations work the same way.
The VoIP phone system works the same way so you can ring the station using a "local" Cambridge number. This often lead to strange conversations when people dialled the wrong number and found out they had accidentally phoned the Antarctic.

Most would agree that they appear to be correlated.
This shows a close up of the increase in CO2 since the industrial revolution (time axis reversed from other plot):

The sudden CO2 increase is consistent with the quantity of CO2 output from human sources.
It is not hard to understand what is happening. I work for the British Antarctic Survey and my girlfriend is an atmospheric chemist. Many of my friends are climate change or environmental scientists. Let me tell you there is as near to complete agreement about what is happening as it is possible to have in science.
Of course it is possible to find some people who disagree. It would be unhealthy if you couldn't. Science works because of debate.
The post is pretty awful, but what really got me was the claim that because 650 is a bigger number than 52 more people are sceptical than support the IPCC. That is laughable:

Some of the techniques could be just what a start-up needs to give it the edge over, "just good enough" web apps.
simoncoggins | 17 years ago | on: Microsoft tries to one-up Google PageRank
The two challenges are gathering the information and interpreting it. Logging which links are clicked is obviously easy but not necessarily a good indicator of interest (for instance I'll often Ctrl-Click a number of links then read them rather than click one at a time until I find what I want).
It sounds like they are using a representative sample of users with a plug in to allow them to collect more advanced information (such as time spent) which is an interesting approach.
I can imagine that there may be false positives though - for instance a site that looks like it should contain the desired information (but actually doesn't) might occupy users for longer than a page with the answer they want right at the top.

My first thought was how it relates to Microsoft as mentioned in this article: http://seekingalpha.com/article/80363-why-microsoft-will-nev... . Their fear of web apps undermining Windows/Office prevented them from taking a lead in the emerging market.
