2600: The Hacker Quarterly How to Get Startup Ideas November 2012 The way to get startup ideas is not to try to think of startup ideas. It's to look for problems, preferably problems you have yourself. The very best startup ideas tend to have three things in common: they're something the founders themselves want, that they themselves can build, and that few others realize are worth doing. Problems Why is it so important to work on a problem you have? I made it myself. Why do so many founders build things no one wants? At YC we call these "made-up" or "sitcom" startup ideas. For example, a social network for pet owners. The danger of an idea like this is that when you run it by your friends with pets, they don't say "I would never use this." Well When a startup launches, there have to be at least some users who really need what they're making—not just people who could see themselves using it one day, but who want it urgently. Made-up startup ideas are usually of the first type. Nearly all good startup ideas are of the second type. Self School
codecademy Ruby is a powerful, flexible programming language you can use in web/Internet development, to process text, to create games, and as part of the popular Ruby on Rails web framework. Ruby is: High-level, meaning reading and writing Ruby is really easy—it looks a lot like regular English!Interpreted, meaning you don't need a compiler to write and run Ruby. You can write it here at Codecademy or even on your own computer (many are shipped with the Ruby interpreter built in—we'll get to the interpreter later in this lesson).Object-oriented, meaning it allows users to manipulate data structures called objects in order to build and execute programs. This course assumes no previous knowledge of Ruby in particular or programming/computer science in general. Cain & Abel Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, recovering wireless network keys, revealing password boxes, uncovering cached passwords and analyzing routing protocols. The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort. It covers some security aspects/weakness present in protocol's standards, authentication methods and caching mechanisms; its main purpose is the simplified recovery of passwords and credentials from various sources, however it also ships some "non standard" utilities for Microsoft Windows users. The latest version is faster and contains a lot of new features like APR (Arp Poison Routing) which enables sniffing on switched LANs and Man-in-the-Middle attacks.
My MOOCs - snarkychaser The Scientific American article sat there every time we used the bathroom. I really didn’t have a chance to read it but it involved MOOCs (massive online courses) bringing first rate education to Rwanda. That same summer as we drove all over California to visit colleges for my teenaged daughter, she struggled to find internet access to take her tests from the University of Melbourne MOOC on Epigenetics. My husband and I were fascinated by her dedication to learn and I became sold on the idea of MOOCs. This winter, when my twitter feed posted an article in the Atlantic Monthly about the edX, collaboration with Harvardx and MITx and their MOOC platform, I jumped right in to sign up. · BerkeleyX: ColWri2.2x Principles of Written English (a basic college essay writing class) taught by Dr. · BerkleeX: BCM-MB110x Introduction to the Music Business taught by John P.

Ruby en vingt minutes Introduction Ce court tutoriel ne devrait pas prendre plus de vingt minutes de votre temps. Il part du principe que vous avez déjà installé Ruby ; si ce n’est pas le cas, il vous est chaleureusement conseillé de le faire avant de poursuivre votre lecture. Note: le traducteur a ici considéré qu’il était plus pertinent de conserver l’entièreté du code en anglais, plutôt que de présenter un mélange en « franglais » de mot-clés anglais et noms de variables français. L’usage d’un langage de programmation, quel qu’il soit, nécessite hélas (?) Interactive Ruby Une première approche de Ruby, la plus simple, consiste à utiliser IRB (Interactive Ruby) dans un terminal : si vous utilisez macOS, ouvrez un Terminal et tapez irb, puis appuyez sur [Entrée] ; si vous êtes sous Linux, ouvrez une console et tapez irb, puis appuyez sur [Entrée] ; si enfin, vous utilisez Windows, lancez Interactive Ruby qui se trouve dans la section Ruby du menu Démarrer > Applications. irb(main):001:0> Voilà, IRB est lancé.

and Harvard release working papers on open online courses MIT and Harvard University today announced the release of a series of working papers based on 17 online courses offered on the edX platform. Run in 2012 and 2013, the courses analyzed drew upon diverse topics — from ancient Greek poetry to electromagnetism — and an array of disciplines, from public health to engineering to law. The working paper series features detailed reports about individual courses; these reports reveal differences and commonalities among massive open online courses (MOOCs). In the coming weeks, data sets and interactive visualization tools will also be made available. The papers analyze an average of 20 gigabytes of data per course and draw on interviews with faculty and course teams as well as student metrics. Key takeaways Takeaway 1: Course completion rates, often seen as a bellwether for MOOCs, can be misleading and may at times be counterproductive indicators of the impact and potential of open online courses.

Access to MOOCs could be revolutionary, but US foreign policy is preventing that | Aasis Vinayak Recently, Coursera, the online university course provider, began blocking students from Iran, Cuba and Sudan from using its services. Coursera, which boasts more than 21.5 million student enrolments from 190 countries, is one of the most popular MOOC (Massive Open Online Course) platforms out there. But unlike other MOOCs (like MIT OpenCourseWare or edX), Coursera is a for-profit business, which means it can't serve students in countries against which the US government has imposed economic sanctions. According to the US treasury, trade in "information and informational materials" is permitted between the US and countries like Iran, which is why online newspapers and some search engines can provide content to people living in those countries. In reality, almost all the courses offered by Coursera are free. The export control regulations governing MOOCs are unclear. Another difficulty is with the acronym itself. MOOCs allow users to enrol in a variety of courses with ease.
