- ReWalk Robotics Exoskeleton — first exoskeleton for the paralyzed to receive regulatory approval; 66 bought so far, 11 with reimbursement from insurance. The software upgrades for the ReWalk 6.0 provide a smoother walking gait (with less of a soldier-like marching step), an easier stopping mechanism, and a much-improved mode for ascending and descending stairs. The user wears a wristwatch-like controller to switch the suit between sit, stand, walk, and stair modes. How long until a cheaper version hits the market, but you don’t always get to control where it takes you if there’s a sale on featuring brands you love? (via IEEE)
- Bitcoin Trends in First Half of 2015 — 94% increase in monthly transactions over the past year. 47% of Coinbase wallet holders are now from countries outside the U.S.
- Socket.io p2p — an easy and reliable way to set up a WebRTC connection between peers and communicate using the socket.io-protocol.
- 18F Content Guide — communications guide for government content writers that bears in mind the frustrations citizens have with gov-speak websites.
Bio-Writing, Internet Fame, Obama's Tech, and Precog Software
- How to Write a Good Bio (Scott Berkun) — something we all have to do, and rarely do well the first time. Excellent advice.
- Scumbag Steve’s Advice for Annoying Facebook Girl — Some people can’t distinguish the internet from real life. There are people who refuse to believe my name isn’t Steve and that I am not really the scumbag (well not all the time, that is). Just remember who you are. And that you know you’re a decent kid. Blake (the guy whose image was adopted as “Scumbag Steve” by meme-makers) was 21 when he wrote that, and it remains the best advice for anyone dealing with sudden visibility in the public eye.
- The Battle for Obama’s Tech (The Verge) — same old story: the software that got Obama elected won’t be released. Instead it’ll atrophy and have to be rewritten in four years’ time. How do I know this? The morons at the Democratic Party did it with Kerry’s run and again for Obama’s first campaign. It’s a choice the OFA developers warn could not only squander the digital advantage the Democrats now hold, but also severely impact their ability to recruit top tech talent in the future.
- Precog Software (Wired) — researchers assembled a dataset of more than 60,000 crimes, including homicides, then wrote an algorithm to find the people behind the crimes who were more likely to commit murder when paroled or put on probation. Berk claims the software could identify eight future murderers out of 100. The software parses about two dozen variables, including criminal record and geographic location. The type of crime and the age at which it was committed, however, turned out to be two of the most predictive variables. […] The software aims to replace the judgments parole officers already make based on a parolee’s criminal record and is currently being used in Baltimore and Philadelphia. I look forward to the study comparing human judgement from parole officers against algorithmic judgement.
A letter asking for an introduction meets a meditation on self-reliance.
In 1905 Mark Twain wrestled with the sort of request that many readers here have undoubtedly encountered: a new writer with the most tenuous of connections (her uncle was briefly a neighbor in a Nevada mining town) asks Twain to use his influence to get her manuscript published.
It never hurts to carry an introduction from a well-regarded intermediary, as long as your introducer can actually speak to the quality of your work. I think of Twain’s anguished reply every time I’m asked to recommend someone or something I don’t know — or am tempted to ask the same favor of someone else.
Twain’s message is ultimately optimistic: don’t simply try to accumulate influence. Instead, come up with a good idea and sell it on its merits. The world will listen.
Text Analysis Bundle, Scala Probabilistic Modeling, Game Analytics, and Encouraging Writing
- Pattern — a BSD-licensed bundle of Python tools for data retrieval, text analysis, and data visualization. If you were going to get started with accessible data (Twitter, Google), the fundamentals of analysis (entity extraction, clustering), and some basic visualizations of graph relationships, you could do a lot worse than to start here.
- Factorie (Google Code) — Apache-licensed Scala library for a probabilistic modeling technique successfully applied to […] named entity recognition, entity resolution, relation extraction, parsing, schema matching, ontology alignment, latent-variable generative models, including latent Dirichlet allocation. The state-of-the-art big data analysis tools are increasingly open source, presumably because the value lies in their application not in their existence. This is good news for everyone with a new application.
- Playtomic — analytics as a service for gaming companies to learn what players actually do in their games. There aren’t many fields untouched by analytics.
- Write or Die — iPad app for writers where, if you don’t keep writing, it begins to delete what you wrote earlier. Good for production to deadlines; reflective editing and deep thought not included.
Access Over Ownership, Retro Programming, Replaying Writing, and Wearable Sensors
- Steve Case and His Companies (The Atlantic) — Maybe you see three random ideas. Case and his team saw three bets that paid off thanks to a new Web economy that promotes power in numbers and access over ownership. “Access over ownership” is a phrase that resonated. (via Walt Mossberg)
- Back to the Future — teaching kids to program by giving them microcomputers from the 80s. I sat my kids down with a C64 emulator and an Usborne book to work through some BASIC examples. It’s not a panacea, but it solves a lot of bootstrapping problems with teaching kids to program.
- Replaying Writing an Essay — Paul Graham wrote an essay using one of his funded startups, Stypi, and then had them hack it so you could replay the development with the feature that everything that was later deleted is highlighted yellow as it’s written. The result is fascinating to watch. I would like my text editor to show me what I need to delete ;)
- Jawbone Live Up — wristband that sync with iPhone. Interesting wearable product, tied into ability to gather data on ourselves. The product looks physically nice, but the quantified self user experience needs the same experience and smoothness. Intrusive (“and now I’m quantifying myself!”) limits the audience to nerds or the VERY motivated.
