I'm not sure it matters for most sites that the CAPTCHAs is crackable. Consider that you have some low profile site. Think of a cost benefit analysis for a spammer to write the code to break a non standard captcha, the cost is an hour of time say, the benefit is very low, maybe a few spam message will get through, which are quickly deleated. So basically its just not worth the spammers effort to break your custom capture. This is fine for most small site, it would not work for the likes of microsoft where there is considerable higher benefit. I've done this on my site and no one has bothered to break it.

Excession was one of my favourites, I really liked the idea of the ships as central character, vastly more intelligent than the humans. And the Outside Context Problem experienced by these minds really tickled me.
AdSense is nice as it removes most potential for advertisers influencing content. What WP needs to avoid at all cost is bargaining with advertisers - positive article content in exchange for advertising revenue.
On my site pfaf.org I use a simple Q&A type CAPTCHA plus human moderation. A non-standard captcha means that the cost for a spammer goes up, they have to write a specific code to break the captcha. The human moderation means that they get 0 value for sucess. End result they don't bother. My work is vastly reduced by using the capture as no spam to deal with.
The two proof deletion debates, the other one being Boy's surface Proof AfD are a partially a matter of house keeping, over time some fine proof articles have emerged for instance Proof that 22 over 7 exceeds , others are not to as high a standard. Indeed there are 43 proof articles proof articles of varying quality. Some such as the Boys Surface one are week and lack links to any external sources so lack any means of verification. Its standard practice in mathematics for results to go through peer review and without links there is no evidence of peer review. Yes the proof could be checked by wikipedia editors but this goes against the wikipedia policy of no original research.
But this is not an example of a failure cascade, because the decline is non critical, drops will eventually flatten out. Here we see more sinusoidal fluctuations. Indeed it would be unlikely to see a failure cascade for either of the two main parties as both have very solid core supporters. A smaller party would be more likely to see a failure cascade, here success in getting vote share would become more important strong positive feedback when votes are incressing but when the votes start to drop the feedback spells for rapid declain. Another ingredient in a political party would be an element of ideology/belief, for the core voters this beleif will make them stick to the party no matter how strong the decline.
I ran in to this problem back in the days where 4MB of memory was a lot. My program needed a lot of large objects with a short persistence. The upshot of this was that the program soon ground to a halt due to swapping memory I partially overcame the problem by writing my own allocation algorithm which kept separate lists of blocks of different sizes, hence it managed to recycle much of the memory blocks.
Indeed very dodgy reasoning in the article. For one if you lost a save game and replayed from the start you would problem take less time to get to the same point again, as you know the route. You would also need to factor in the can I be bothered quotient. Also it depends on if you lost all your save games or just one, in the latter case its the time taken from the previous save.
Lie groups and Lie Algebras are different, yes there is an E11 Lie Algebra, but I don't know if there is a corresponding Lie Group. E11 is a very different beast to E8 it being infinite dimensional and it does not have the same correspondence with coxeter groups etc.
As other had said it is not the biggest Lie group, there are two families Ak and Dk of lie groups which are infinite sequences. You can think of Ak as the symmetry of the trianagle, tetrahedron, 4-simplex,..... there one of these for each dimension. Likewise Dk is related to the symetry of the square, cube, hyper-cube and n-dimensional cube. To these are added the so called exceptional groups, sort of like the icoshedron and its four dimensional analogue. It just so happens that these do not for an infinite sequence, higher dimensional spaces kind of get simpeler after a while which don't allow for E_11 to exist.
Open proxies are well know for being used by spammers and other lowlife. Hence a fair few site will restrict access to known open proxie IP's. That's one of the reason why the lists of proxies are held. Wikipedia tends to block open proxies on sight as they are a well know route for persistent vandals.
There are basically two forms of tilling patterns, the periodic patterns which have been known for many years, and aperiodic ones, which have only been recently been discovered. For many years it was thought that only the periodic patterns existed, and in particular there were no patterns with five fold symmetry.
The patterns shown in the article are not true penrose patterns, it exhibits two lines of reflection, horizontal and vertical and the pattern does not repeat indefinitely.
It's amazing to see they're still mistaking road signs for pedestrians.
These sorts of mistakes seem very common in computer vision, the system I used a few years back was forever mistaking trees for people. The problem is that there is a lot of variation in how people can look: what angle you are looking at them from, how their body is positioned and the colour of the clothes they wear. Creating an algorithm which can recognise all this variation can often lead to a system with many false positives.
It looks like they are doing a harder task of analysing static images, things get a bit easier with a video as you can add information from movement. People tend to move road signs tend not to.
No actually, a well though through and considered response about a specifics of UK law relating to the changes in agricultural funding systems. I also got a reply on the issue of software pattents, and my MP asked questions about this of the european commitee on the topic.
If you want to be taken seriously in a democracy you first need to give up your anonominity. MP as our elective represantatives have a certain obligation to respond to members of their constituancies.
The FaxYourMP service by this group is probably a better method to communicate your view than the petitions. I've used it a couple of times and both times got supportive responses from my MP and once got a reply from the secretary of state.
I can see this could be a problem. I run a yahoo group with 18 AOL users on it and have never experienced this sort of problem. There might be an advantage of using a well-known service like yahoo. As yahoo is know to have a strict anti-spam policy theres porbably a higher chance of these messages being labeled as not spam. Just a thought?
It seems like Wales is on a project creation frenzy, it seems like every month theres yet another project launched from Wales and Beesley. Actually I exaggerate but the previous big announcement http://campaigns.wikia.com/ seems to be pretty inactive now. I fear the same will happen for the new search engine. Does jimbo have the time to dedicate to making this happen, or is it vapor-ware?

His example of good habit with mkdir did not convince me
$ cd tmp/a/b/c || mkdir -p tmp/a/b/c
If the directory exists you end up in the directory, if it does not it creates the directory but leaves you where you first started. Hence you don't know which directory you will be in after the command is executed!

As a wikipedia maths editor yes we have been caught short by this. E8 is a pretty obscure topic, out of about 10,000 maths articles kind of low down the priority list. You may find http://en.wikipedia.org/wiki/Coxeter-Dynkin_diagra m, http://en.wikipedia.org/wiki/Circle_group, http://en.wikipedia.org/wiki/Lie_group, and http://en.wikipedia.org/wiki/Root_system to be related articles which may be a little easier to understand.
As with any open source project, if you don't like it fix it. Theres plent of articles which could do with someone taking the time to write in terms more accessable to the layman.

RuneQuest had a system of hit location. It tended to make combat more risky.
If you have firefox and web-dev tool bar you can get rind of the popups by disableing the CSS styles.
