I can only hope that they never decide to implement "lolreverts"

Sometimes a one-line text-only description of your git commits just isn't enough. For those types of scenarios there is software called "lolcommits" that is available for Windows, Mac, and Linux that, when enabled, takes a photo with your webcam every time you commit your code via git. Now you can really let your co-workers know how you feel about having to fix their whitespace issues all the time with just a simple facial expression. After the photo is taken, the git message is overlayed on top of the image is a style reminiscent of lolcats. The resulting image files are then stored locally in your home directory. [more inside]

Why I Am Not a Maker

There’s a widespread idea that “People who make things are simply different [read: better] than those who don’t.” [...] It’s not, of course, that there’s anything wrong with making (although it’s not all that clear that the world needs more stuff). The problem is the idea that the alternative to making is usually not doing nothing—it’s almost always doing things for and with other people, from the barista to the Facebook community moderator to the social worker to the surgeon. Describing oneself as a maker—regardless of what one actually or mostly does—is a way of accruing to oneself the gendered, capitalist benefits of being a person who makes products. [more inside]

Computer Scientists Make the Same Salary, Whether Male or Female.

Female Computer Scientists Make the Same Salary as Their Male Counterparts - for a while. Whatever the reasons for the gender disparity in programming, at least to begin with, there's no actual salary difference between female and male programmers. According to a new study by the American Association of University Women, [PDF] there is no statistical difference between female and male programmers salaries one year out of college. The same holds true for women who go into engineering, mathematics and physical sciences" [more inside]

Out of the Tar Pit: Analysis of Software Complexity

Out of the Tar Pit (SL-GitHub to PDF) by Ben Moseley and Peter Marks. Abstract:
Complexity is the single major difficulty in the successful development of large-scale software systems. Following Brooks we distinguish accidental from essential difficulty, but disagree with his premise that most complexity remaining in contemporary systems is essential. We identify common causes of complexity and discuss general approaches which can be taken to eliminate them where they are accidental in nature. To make things more concrete we then give an outline for a potential complexity-minimizing approach based on functional programming and Codd’s relational model of data.

I put my thing down, flip it and reverse it

If you've ever typed anything into a Google Doc, you can now play it back as if it were a movie — like traveling through time to look over your own shoulder as you write.

This is possible because every document written in Google Docs since about May 2010 has a revision history that tracks every change, by every user, with timestamps accurate to the microsecond; these histories are available to anyone with "Edit" permissions; and I have written a piece of software that can find, decode, and rebuild the history for any given document.

How does ('' == [] && this); make programmers feel?

Programming language subreddits and their choice of words presents an interactive chord graph showing how often particular languages are mentioned in other languages' communities. Another chart shows how proportional others' mentions are to the TIOBE Index. And some very elementary sentiment analysis suggests how often each language inspires pure theory, happiness and fun, or cursing. A tongue-in-cheek aside reveals that counting infrequently-mentioned languages yields another happiness/coolness chart that puts Elm at the top, just above other surprises.

girls and technology!

WYNC's Manoush Zomorodi investigates the gender gap in tech and computer science, and finds a number of people working towards bridging that gap, from childhood to university: completely restructuring a required computer science course to make it more welcoming to female university students, celebrating women in computing history (and recognizing that computer science wasn't so male-dominated, and making children's books and toys (even dollhouses!) for kids to explore programming concepts on their own. She also noticed that the majority of female computer science students in the US had grown up overseas - possibly because computer science isn't a common subject in American high schools. This is slated to change: a new AP Computer Science subject is in the works, with efforts to get 10,000 highly-trained computer science teachers in 10,000 high schools across the US.

An excellent programming language for data analysis

"Julia is a high-level, high-performance dynamic programming language for technical computing."

I Can Tell By The Pixels

Visualizing Algorithms shows you how computer algorithms can be represented visually, leading to better understanding of how the algorithms work:

"Have you ever implemented an algorithm based on formal description? It can be hard! Being able to see what your code is doing can boost productivity. Visualization does not supplant the need for tests, but tests are useful primarily for detecting failure and not explaining it. Visualization can also discover unexpected behavior in your implementation, even when the output looks correct."

Eigendemocracy: crowd-sourced deliberative democracy

Scott Aaronson on building a 'PageRank' for (eigen)morality and (eigen)trust - "Now, would those with axes to grind try to subvert such a system the instant it went online? Certainly. For example, I assume that millions of people would rate Conservapedia as a more trustworthy source than Wikipedia—and would rate other people who had done so as, themselves, trustworthy sources, while rating as untrustworthy anyone who called Conservapedia untrustworthy. So there would arise a parallel world of trust and consensus and 'expertise', mutually-reinforcing yet nearly disjoint from the world of the real. But here's the thing: anyone would be able to see, with the click of a mouse, the extent to which this parallel world had diverged from the real one." [more inside]

s/camel/_/

Right now someone who works for Facebook is getting tens of thousands of error messages and frantically trying to find the problem before the whole charade collapses. There's a team at a Google office that hasn't slept in three days. Somewhere there's a database programmer surrounded by empty Mountain Dew bottles whose husband thinks she's dead. And if these people stop, the world burns. Most people don't even know what sysadmins do, but trust me, if they all took a lunch break at the same time they wouldn't make it to the deli before you ran out of bullets protecting your canned goods from roving bands of mutants.

The Wisdom of Crowds

For the past three days, the world of streaming gaming has been riveted by an unlikely phenomenon: Twitch Plays Pokemon. Consisting of a live Twitch.TV chatroom hooked up to a classic Game Boy emulation of Pokémon Red, the program is set to recognize a limited number of commands and execute them in real time, allowing an audience of tens of thousands to collectively control the action as they watch. An astonishing amount of progress has been made, including the dramatic last-second defeat of a third gym leader (GIF) and the solution of a notoriously tricky puzzle on the very first attempt. But all for naught, it seems, as Team Twitch finds itself hilariously stranded on the ledges of Route 19 where, as one viewer explained, "they basically have to walk a small path for about ten spaces without anyone pushing down and jumping Red off the ledge," a grim democratic reality the dedicated subreddit /r/twitchplayspokemon has had all kinds of fun with over the last dozen ludicrous hours.

“We are able to see just a narrow angle, whatever we do."

It was not the first time that Adam Magyar has had to explain his work to mystified observers. Born in Hungary in 1972, Magyar began taking pictures in his late twenties, roaming the streets of Asian cities and capturing images of Indian street vendors, Hindu holy men, and Himalayan students. His work evolved rapidly from conventional documentary photography to surreal, radically experimental imagery that reflects his obsession with finding innovative new uses for digital technology. A self-taught engineer and software designer who assembled his first computer while in his teens, Magyar captures his images using some of the world’s most sophisticated photographic equipment, modified with software he writes himself. Additional code, also of his own design, removes nearly all distortion, or “noise,” from his data, producing images of remarkable clarity.
