Finding Moonshine: Dara O'Briain's School of Hard Sums
I am co-hosting a mad comedy maths game show with Dara O'Briain on the TV channel Dave. I was away filming for another series last week when an episode was aired that required some calculus. I got lots of tweets and emails about the problem so thought it worth just explaining how you solve it. It's got some great maths in it. Problem: A lifeguard at the beach spots a swimmer in distress in the water. They need to run across the sand to the water and then swim out to rescue the swimmer. Lets suppose the lifeguard's running speed is v1 and swimming speed is v2. We note that v1=2*v2. There is also a cute physical way you could use to solve this puzzle. When you set the differential to 0 and expand it then they will get a quartic polynomial. At school you learn about a formula for solving quadratic equations. Glorious...if you like that kind of thing. Why do we need to do quadratic equations at school? Solving quadratic equations is something we do every time you catch a ball.

New cool list of Linux must-have programs
Update: A new, up-to-date collection is available. Please take a look! It's been approximately two years since I've written the first article, A (cool) list of Linux tools. The article proved quite popular with my audience, as it allowed Linux users, new converts in particular, a quick taste of some of the more useful programs available for Linux platforms, across a range of categories. Since, a lot has changed. Changes from the last time Like the last time, the programs will be sorted by categories. Games I will not be listing games here. Users' recommendations Likewise, there's a users' recommendation sub-section, so you can send me your suggestions and ideas. Table of Contents: Backup software File backup software Unison Unison is a simple, lightweight backup program. TimeVault TimeVault is a snapshot software, which, when activated will create copies of all files and folders that change, retained a detailed archive of all revisions.

The Grey Labyrinth: The Labyrinthians' Exchange
by Kevin J. Lin Two exceptionally quick-witted Labyrinthians were invited to a party in their honor. The party was to be held in a private house in the city of Mathematica. Mathematica, predictably, is laid out in a perfect grid. Every house's address is composed of two positive numbers, indicating its relative position to the Townhall in the southwest corner. Currently Mathematica is one hundred by hundred houses in area. Our two famed puzzlers, let's call them Samantha and Paul, were both given the address weeks in advance. Paul: I'm afraid I've forgotten the address. Paul and Samantha were being perfectly truthful, and no other information was exchanged apart from this dialog. What was the party's address?
Screen, le meilleur ami du geek nomade
[via IRC (merci - t'ain j'me rappelle plus qui... davee ? fuzzix ?)]Je cherchais un moyen sous bash de lancer un programme, le couper (ou le mettre en sommeil), puis de le récupérer pour le relancer... sur un autre bash. Jobs Les premières étapes sont relativement connues. Ce qui vient en italique l'est beaucoup moins.Pour "stopper" un processus, c'est connu, il faut faire Ctrl-Z. On peut continuer à bosser dans ce terminal, le processus gelé reste bloqué en attendant soit de mourir (tué par un logout de la console, ou par la commande kill), soit d'être réactivé.En l'occurrence, dans la liste des processus suspendus, monsieur vi a le numéro 1. Ubiquïté limitée Une des contrainte de la petite manip avec jobs, c'est qu'il ne peut manipuler que les processus dans la console "mère" du processus.Imagine que j'ai gêlé un processus dans la console n°1 :$ jobs[1]+ Stopped vi toto.txt Pleins feux sur screen La doc me dit : Bleh?
