- A General Technique for Automating NES Games — software that learns how to play NES games and plays them automatically, using an aesthetically pleasing technique. With video, research paper, and code.
- rietveld — open source tool like Mondrian, Google’s code review tool. Developed by Guido van Rossum, who developed Mondrian. Still being actively developed. (via Nelson Minar)
- KPI Dashboard for Early-Stage SaaS Startups — as Google Docs sheet. Nice.
- Life Without Sleep — interesting critique of Provigil as performance-enhancing drug for information workers. It is very difficult to design a stimulant that offers focus without tunnelling – that is, without losing the ability to relate well to one’s wider environment and therefore make socially nuanced decisions. Irritability and impatience grate on team dynamics and social skills, but such nuances are usually missed in drug studies, where they are usually treated as unreliable self-reported data. These problems were largely ignored in the early enthusiasm for drug-based ways to reduce sleep. [...] Volunteers on the stimulant modafinil omitted these feedback requests, instead providing brusque, non-question instructions, such as: ‘Exit West at the roundabout, then turn left at the park.’ Their dialogues were shorter and they produced less accurate maps than control volunteers. What is more, modafinil causes an overestimation of one’s own performance: those individuals on modafinil not only performed worse, but were less likely to notice that they did. (via Dave Pell)
ENTRIES TAGGED "metrics"
Automating NES Games, Code Review Tool, SaaS KPIs, and No Free Lunch
Open Source Metrics, BitTorrent to TV, Tumblr Value, and Variable Fiction
- Open Source Metrics — Talking about the health of the project based on a single metric is meaningless. It is definitely a waste of time to talk about the health of a project based on metrics like number of software downloads and mailing list activities. Amen!
- BitTorrent To Your TV — The first ever certified BitTorrent Android box goes on sale today, allowing users to stream files downloaded with uTorrent wirelessly to their television. The new set-top box supports playback of all popular video formats and can also download torrents by itself, fully anonymously if needed. (via Andy Baio)
- Tumblr URL Culture — the FOO.tumblr.com namespace is scarce and there’s non-financial speculation. People hoard and trade URLs, whose value is that they say “I’m cool and quirky”. I’m interested because it’s a weird largely-invisible Internet barter economy. Here’s a rant against it. (via Beta Knowledge)
- Design-Fiction Slider Bar of Disbelief (Bruce Sterling) — I love the list as much as the diagram. He lays out a sliding scale from “objective reality” to “holy relics” and positions black propaganda, 419 frauds, design pitches, user feedback, and software code on that scale (among many other things). Bruce is an avuncular Loki, pulling you aside and messing with your head for your own good.
Civil Drones, Fencing the Public Domain, Quantified Spy, and Data Daemons for Fun and Metrics
- Helping Drones Play Nice With Other Aviation — The U.S. airspace is quickly being filled with simultaneously flying drones. To such an extent, unmanned aircraft could soon become a nightmare for the ATC controllers. The ADS-B will improve Predator B’s crew situational awareness making the drone capable to operate more freely and safely in domestic and international airspace in accordance with civilian air traffic and airspace rules and regulations.
- Reclaiming NZ’s Digitised Heritage — Out of a sample of 100 books: 50% of NZ Heritage Books (published before 1890) have been digitised; 90% of digitised texts are fully accessible; 98% of accessible texts are downloadable; Despite all works being in the public domain, only one did not have any licencing restrictions applied to its use. Most groups who digitise then go on to put restrictions around their use. [T]here are also many instances where arbitrary restrictions are being applied to the detriment of the public good.
- Self-Spy (GitHub) — Log everything you do on the computer, for statistics, future reference and all-around fun!
- statsd (GitHub) — Etsy’s data-gathering daemon, written up in an excellent blog post.
Decoding ToS, Impact Factors are Nonsense, Crappy Open Source Code, and Data Mining History
- TOS;DR — terms of service rendered comprehensible. “Make the hard stuff easy” is a great template for good ideas, and this just nails it.
- Sick of Impact Factors — typically only 15% of the papers in a journal account for half the total citations. Therefore only this minority of the articles has more than the average number of citations denoted by the journal impact factor. Take a moment to think about what that means: the vast majority of the journal’s papers — fully 85% — have fewer citations than the average. The impact factor is a statistically indefensible indicator of journal performance; it flatters to deceive, distributing credit that has been earned by only a small fraction of its published papers. (via Sci Blogs)
- A Generation Lost in the Bazaar (ACM) — Today’s Unix/Posix-like operating systems, even including IBM’s z/OS mainframe version, as seen with 1980 eyes are identical; yet the 31,085 lines of configure for libtool still check if and exist, even though the Unixen, which lacked them, had neither sufficient memory to execute libtool nor disks big enough for its 16-MB source code. [...] That is the sorry reality of the bazaar Raymond praised in his book: a pile of old festering hacks, endlessly copied and pasted by a clueless generation of IT “professionals” who wouldn’t recognize sound IT architecture if you hit them over the head with it. It is hard to believe today, but under this embarrassing mess lies the ruins of the beautiful cathedral of Unix, deservedly famous for its simplicity of design, its economy of features, and its elegance of execution. (Sic transit gloria mundi, etc.)
- History as Science (Nature) — Turchin and his allies contend that the time is ripe to revisit general laws, thanks to tools such as nonlinear mathematics, simulations that can model the interactions of thousands or millions of individuals at once, and informatics technologies for gathering and analysing huge databases of historical information.
Why businesses should care about speed.
In this Velocity Podcast, Strangeloop's Joshua Bixby discusses the business of speed and why web performance optimization is an institutional need.
jQuery Video Plugin, Open Source Data View, QR Insanity, and Measuring Citizen Science
- jPlayer — jQuery plugin for audio and video in HTML5. Dual-licensed MIT and GPL.
- QR Code Madness — I recently received an MMS (multimedia text message) with a picture to a QR code. First, it’s bad enough advertising agencies still randomly text people ads. Second, what am I supposed to scan that with? My eyes? But check out the photo for maximum silliness.
- Galaxy Zoo: Crowdsourcing Citizen Scientists (Guardian) — yes, the headline is a collection of buzzwords but the Galaxy Zoo project remains fantastic. My eye was caught by Working 12 hours a day non-stop for a week, [Kevin] Schawinski had managed the not inconsiderable task of detailing the characteristics of 50,000 galaxies. He needed a pint. [... they built Galaxy Zoo in a day of two ...] Within 24 hours of it being announced on Lintott’s website, Galaxy Zoo was receiving 70,000 classifications an hour. They still measure their hit-rate in “Kevin weeks” – a unit of 50,000. “Soon after that we were doing many Kevin weeks per hour,” Schawinski says. (via Roger Dennis)

How metrics-driven decisions can build better software teams.
Don't dismiss "Moneyball" just because it began in the sports world. Many of the system's metrics-based techniques can also apply to software teams.
Lou Rosenfeld on the benefits of parsing and refining site search.
A gold mine is hiding in the data generated by website search engines, yet many site owners pay little attention to the analytics those engines yield. Author Lou Rosenfeld explains why site search is worth your time.
