SSH tricks

Why SSH? As recently as a 2001, it was not uncommon to log in to a remote Unix system using telnet. Telnet is just above netcat in protocol sophistication, which means that passwords were sent in the clear. As wifi proliferated, telnet went from security nuissance to security disaster. As an undergrad, I remember running ethereal (now wireshark) in the school commons area, snagging about a dozen root passwords in an hour. SSH, which encrypts and authenticates connections, had been in development since 1995, but it seemed to become adopted nearly universally and almost overnight around 2002. It is worth configuring SSH properly: per-user configuration is in ~/.ssh/config; system-wide client configuration is in /etc/ssh/ssh_config. Key-based, passwordless authentication Key-based passwordless authentication makes it less cumbersome for other programs and scripts to piggyback atop SSH, since you won't have to re-enter your password each time. To set this up, first log in to the client machine.

Behance Outfitter :: Products :: Dot Grid Book For too long, Creatives have suffered from inefficiency, disorganization, and careers at the mercy of bureaucracy. Behance aims to organize, connect, and empower creative careers, so the best ideas can see the light of day. Behance’s “Action” and “Dot Grid” product lines have become indispensable utilities for Creatives at work. Back in 2006, when the Behance team was just imagining ways to organize and empower creative people, they knew that they needed to start with themselves. As Scott Belsky and Matias Corea from Behance tell the story, "Brainstorming from our apartments during the hours outside our day jobs, we used our personal Action Pads to capture and complete countless action steps that ultimately pushed Behance from vision to reality. "In 2007, at the insistence of friends who wanted Action Pads of their own, we expanded the line and made it available online and through select stores like the Museum of Modern Art in San Francisco."

La programmation pour les non-programmeurs Comment apprend-t-on à jongler avec les concepts et abstractions des langages informatiques ? Le Monde | • Mis à jour le | Par Rémi Sussan Programmer, c’est difficile : penser logiquement, par étapes, sans en sauter aucune et en envisageant toutes les possibilités de ses actions demande une grande attention, une grande rigueur. Mais à ces complications s’ajoute encore l’apprentissage d’une syntaxe extrêmement ardue, qui ne supporte pas la moindre faute, à la virgule près. Un autre obstacle, peut-être moins évident, est l’absence de résultats immédiatement gratifiants pour les débutants. L’une des premières tâches de simplification consisterait donc à mettre au point des langages sans possibles erreurs de syntaxe. Un des produits phares du genre, Alice, élaboré à l’université de Carnegie Mellon, permet de créer très rapidement des petits films interactifs en 3D. Kay ne renonça pas pour autant à faire du Smalltalk un langage “pour tous”. Etoys est le plus ancien des deux.

SQL Indexing tutorial for MySQL, Oracle, SQL Server, PostgreSQL, … 10 Open Education Resources You May Not Know About (But Should) This week, the OCW Consortium is holding its annual meeting, celebrating 10 years of OpenCourseWare. The movement to make university-level content freely and openly available online began a decade ago, when the faculty at MIT agreed to put the materials from all 2,000 of the university’s courses on the Web. With that gesture, MIT OpenCourseWare helped launch an important educational movement, one that MIT President Susan Hockfield described in her opening remarks at yesterday’s meeting as both the child of technology and of a far more ancient academic tradition: “the tradition of the global intellectual commons.” We have looked here before at how OCW has shaped education in the last ten years, but in many ways much of the content that has been posted online remains very much “Web 1.0.” But as open educational resources and OCW increase in popularity and usage, there are a number of new resources out there that do offer just that.

For Your Script Loading Needs As JavaScript usage has skyrocketed over the last few years, so has the sheer number of scripts that are being loaded in an average web page. With these script tags comes a lot of baggage, such as blocking and lack of dependency management. Today, I'd like to bring your attention to a number of JavaScript loaders, which are mini toolkits that significantly simplify how you add and load scripts. The Problem with Simple Script Tags They Block the Page The page stops 'happening' while the script is downloaded. JavaScript files loaded using the script tag are blocking by nature. No Easy Way to Manage Dependencies Lack of dependency management is a big drawback. Next up comes the issue of handling dependencies. Available Choices The initial idea for this round up was sparked by a post over at Hacker News about making a list of JavaScript script loaders, roughly a month ago. Now that sufficient time has passed, I think that list is going to be quite massive. HeadJS Author: Tero Piirainen Size: 6.3 KB
