Genetic algorithms are useful for solving all kinds of problems and their implementations can be quite mesmerizing to watch. Re-producing Mona Lisa, a human face or bull cave painting. Playing Super Mario, Tetris and more Tetris. Simulating a soccer team, fishes, ant colony or Santa's flight path. A documentary about using genetic algorithms in design, e.g. deciding the optimal antenna placement on a Humvee, creating search and destroy behavior for UAVs and designing more efficient wind turbine blades. Should probably learn how to stand and jump and stand again before driving.
Every programmer knows that debugging is hard. Great debuggers, though, can make the job look simple. " That attitude is illustrated in an anecdote from IBM's Yorktown Heights Research Center. A programmer had recently installed a new workstation. All was fine when he was sitting down, but he couldn't log in to the system when he was standing up. That behavior was one hundred percent repeatable: he could always log in when sitting and never when standing." [more inside]

But like anything, the original Photoshop was a product of its time. Knoll’s foundations grew to support functionality he’d never imagined; as the features piled on, more staff was added. What started as mostly a photography tool turned quickly into a graphic design powerhouse. And when a port to Windows became inevitable, things started to really get messy.
Photoshop is a city for everyone: how Adobe endlessly rebuilds its classic app.

enchantMOON is a "Hypertext Authoring Tablet" featuring hardware design by Yoshitoshi ABe. For CES the company behind the tablet, Ubiquitous Entertainment, created a series of shorts directed by Evangelion veteran Shinji Higuchi. Some more details about the tablet can be found here and on the official Facebook page. Current details about the UI suggest it takes inspiration from Hypercard and Alan Kay's Dynabook. [more inside]

"We worked through every possible disaster situation," Reed said. "We did three actual all-day sessions of destroying everything we had built."

Broken on Purpose: Why Getting It Wrong Pays More Than Getting It Right - 'It doesn’t end with Facebook, either. Being broken pays off, so social media is often deliberately broken. In fact, nearly every major social network, site or app has greedily pursued this logic.' [more inside]
Bret Victor: We often think of a programming environment or language in terms of its features -- this one "has code folding", that one "has type inference". This is like thinking about a book in terms of its words -- this book has a "fortuitous", that one has a "munificent". What matters is not individual words, but how the words together convey a message. Likewise, a well-designed programing system is not simply a bag of features. A good system is designed to encourage particular ways of thinking, with all features carefully and cohesively designed around that purpose.
Khan Academy unveils its new interactive Computer Science learning platform. More coder resources: Free Tech Books, WiBit.net, Google Code University, the W3C's Web Standards Curriculum, a Beginner's Guide to HTML & CSS, and codepen.io, a social sandbox for web design.
The underlying problem here is that most software is not very good. James Kwak writes in The Atlantic about the economic risks of bad software. Angry mob comments.

This is just the top 30, what I consider to be the most likely candidates for actual new programming jargon based on community upvotes, not just "funny thing that another programmer typed on a webpage and I felt compelled to upvote for hilarity". Because that would be Reddit. Coding Horror presents the top 30 Stack Overflow New Programming Jargon entries.

Falsehoods programmers believe about names and time shows how difficult it can be to represent basic concepts in code.
Following a jury finding that Google had not infiringed upon Oracles patents, a development described as a near disaster for the database company, Judge William Aslup has ruled that the Java APIs cannot be copyrighted. That leaves Oracle with only the 9 lines of rangeCheck code and a handfull of decompiled test files to show for the massivecourt case. CEO Larry Ellison remains confident, claiming that the aquisition of Java creator Sun has still paid for itself.
The 2012 Internet Problem Solving Contest will begin in a couple of days. Read the rules if you want to join in or perhaps just enjoy delving into the archive of past years' problems.
Having previously been disappointed by the information available on the topic, this is my attempt at categorizing different ways to implement 2D platform games, list their strengths and weaknesses, and discuss some implementation details.
Architecture of Open Source Programs The Architecture of Open Source Programs is a guide into the functional implemenation of major opensource code bases. Notable Open Source Projects that are included: BASH, CMAKE, LLVM,GDB,Puppet and PyPy among others

In the main link in griphus' post this morning, there was this little aside: "In 1957...a physics student named Don Knuth built a program for the IBM 650 to help the 1958 Case Institute of Technology basketball team win the league championship." Yes, THAT Don Knuth. Here's a young Don with the team and the IBM 650 (capable of making 50,000 calculations a minute!), and here he is talking about it. [more inside]

"Vitamin R goes straight to the head. Ruby will teach you to express your ideas through a computer. You will be writing stories for a machine. The language will become a tool for you to better connect your mind to the world." Slate compiles the mystery of _why. (Previously).
The Kaspersky analysts over at Securelist uncovered some interesting things deep in the bowels of the code of a trojan. The hooks of the trojan are written using standard, well known languages and interfaces (C++, DLLs and such), but the payload, upon analysis, seems to be written using some heretofore unknown programming language. Can you figure out what language the Duqu trojan is written in? (via Lambda the Ultimate Programming Blog)
"Tech’s latest boom has generated a new, more testosterone-fueled breed of coder. Sure, the job still requires enormous brainpower, but today’s engineers are drawn from diverse backgrounds, and many eschew the laboratory intellectualism that prevailed when semiconductors ruled Silicon Valley.... At some startups the pendulum has swung so far in the other direction that it’s given rise to a new 'title': brogrammer."
