The idea is simple enough — create a crossword style puzzle with regular expressions are the 'clues.' In case you don't know what a regular expression is — it is a way of specifying what characters are allowed using wild-card characters and more. For example a dot matches any single character, an * any number of characters and so on. The regular expression crossword is more a sort of Sudoku puzzle than crossword however because the clues determine the pattern that the entries in a row have to satisfy. It also has to use a hexagonal grid to provide three regular expressions to control each entry. This particular regular expression crossword(pdf) was part of this year's MIT Mystery Hunt. This annual event is crammed with a collection of very difficult problems and the regular expression crossword, created by Dan Gulotta from an idea by Palmer Mebane, was just a small part of the whole — and yes there is a solution."

MojoKid writes "PunkBuster, the anti-cheating service implemented in hundreds of online games, is down. As of the time of writing, the official PunkBuster website is up and down, after having been completely down for the past couple of hours. On Twitter, there are numerous reports of gamers who've been unable to play online in the most popular PunkBuster-backed title of the moment, Battlefield 3. EA has gone as far as to post an interim fix. Applying the fix is a simple matter of extracting an archive and then overwriting a couple of files inside of your Battlefield 3 install folder. While EA has little power over PunkBuster's ability to get things 100% functional again, this issue does highlight the fact that third-party solutions are not always the way to go."
Freshly Exhumed writes "You can't begrudge Nat Brown for claiming some pride in the birth of Microsoft's game console: 'I was a founder of the original xBox project at Microsoft and gave it its name. Almost 14 years after the painful, pointless, and idiotic internal cage-match to get it started and funded, the hard selling of a compelling and lucrative living-room product to Bill (and then Steve as he began to take over), a product that consumers would want and love and demand, I am actually still thrilled to see how far it has come...' But in his recent ILIKE.CODE blog post he is driven to lament that '...as usual, Microsoft has jumped its own shark and is out stomping through the weeds planning and talking about far-flung future strategies in interactive television and original programming partnerships with big dying media companies when their core product, their home town is on fire, their soldiers, their developers, are tired and deserting, and their supply-lines are broken.' Nat goes on to detail a list of Microsoft's past and present strategic Xbox blunders, while tossing some barbs towards Nintendo's and Sony's game console strategies."
