Deleted Transparency, Retro Theme, MPA Suckage, and Ultrasonic Comms
- The Flipside of the Right To Be Forgotten (Business Insider) — deletion requests were granted for a former politician who wanted to remove links to a news article about his behavior when previously in office – so that he can have a clean slate when running for a new position – and a man who was convicted of possessing child sexual abuse imagery.
- BOOTSTRA.386 — gorgeously retro theme for Bootstrap.
- Multi-Process Architectures Suck — detailed and painful look at the computational complexity and costs of multiprocess architectures.
- Chromecast Ultrasonic Comms — In the new system, Chromecast owners first allow support for nearby devices. A nearby device then requests access to the Chromecast, and the Chromecast plays an ultrasonic sound through the connected TV’s speakers. The sound is then picked up by the microphone in the device, which allows it to pair with the TV. (via Greg Linden)
- Mapping the Decentralized Movement (Jon Udell) — the pendulum is about to swing back toward a more distributed Web.
- John Ioannidis: Reproducible Research, True or False? (YouTube) — his talk at Google. (via Paul Kedrosky)
- Docker Misconceptions — This is not impossible and can all be done – several large companies are already using Docker in production, but it’s definitely non-trivial. This will change as the ecosystem around Docker matures (via Flynn, Docker container hosting, etc), but currently if you’re going to attempt using Docker seriously in production, you need to be pretty skilled at systems management and orchestration.
Open Autopilot, Record Robot Sales, NSA Myths Busted, and Informative Errors
- beaglepilot (Github) — open source open hardware autopilot for Beagleboard. (via DIY Drones)
- IFR Robot Sales Charts (PDF) — 2013: all-time high of 179,000 industrial robots sold and growth continues in 2014. (via Robohub)
- The Top 5 Claims That Defenders of the NSA Have to Stop Making to Remain Credible (EFF) — great Mythbusting.
- Netflix’s New Error Message — instead of “buffering”, they point the finger at the carrier between them and the customer who is to blame for slow performance. Genius!
Statistical Sensitivity, Scientific Mining, Data Mining Books, and Two-Sided Smartphones
- Car Alarms and Smoke Alarms (Slideshare) — how to think about and draw the line between sensitivity and specificity.
- 101 Uses for Content Mining — between the list in the post and the comments from readers, it’s a good introduction to some of the value to be obtained from full-text structured and unstructured access to scientific research publications.
- 12 Free-as-in-beer Data Mining Books — for your next flight.
- Dual-Touch Smartphone Concept — brilliant design sketches for interactivity using the back of the phone as a touch-sensitive input device.
Educate Users, Hardware by the Numbers, Humans Beating Computers, Hadoop's Uncomfortable Fit
- How to Educate Users (Luke Wroblewski) — help new users in your app, not in a video.
- Hardware By The Numbers (Renee DiResta) — slides from her keynote at the Solid conference. The mean success rate across all sectors is 19.8%. On average, only 10% of hardware startups raise a second round.
- Humans Beating Computers (Wired) — Newman assembled a small team that became known as the “Air Divers”–the people who would dive deep into the individual complaints and surface with answers. Each was given a couple hundred support tickets connected to a specific issue that the data had identified as a hot-button topic. They would go off and read through each one, then come back and propose a fix. And in the end, this is what turned the situation around. Sometimes it’s easier to put people on the job than try to code the data analysis.
- Hadoop’s Uncomfortable Fit in HPC — Hadoop is being taken seriously only at a subset of supercomputing facilities in the US, and at a finer granularity, only by a subset of professionals within the HPC community.
A software company reaches into the physical world with hardware.
PayPal is a software company, but when I met with Josh Bleecher Snyder, director of software engineering at PayPal, it was to talk about hardware. He’s leading the development of Beacon, PayPal’s new hands-free payment platform. At its heart is a finger-size stick that uses Bluetooth Low Energy to connect with mobile phones and confirm identity.
Paypal’s move into hardware extends its software into the physical world — a key idea behind our Solid Conference. What was once a system confined to screens and keyboards is now part of a new set of interactions in brick-and-mortar stores.
Beacon is part of a vast PayPal stack, and Bleecher Snyder’s team solved problems with a blend of hardware and software thinking — writing code in Go that was efficient enough for Beacon’s processor to be underclocked and avoid overheating, and to anticipate attacks on PayPal’s service that might come from compromised hardware. His entire system hews to PayPal’s “don’t be creepy” mantra by quickly and permanently discarding data that isn’t used in transactions. Read more…
Machine Learning, Deep Learning, Sewing Machines & 3D Printers, and Smart Spoons
- Basics of Machine Learning Course Notes — slides and audio from university course. Watch along on YouTube.
- A Primer on Deep Learning — a very quick catch-up on WTF this is all about.
- 3D Printers Have a Lot to Learn from Sewing Machines — Sewing does not create more waste but, potentially, less, and the process of sewing is filled with opportunities for increasing one’s skills and doing it over as well as doing it yourself. What are quilts, after all, but a clever way to use every last scrap of precious fabric? (via Jenn Webb)
- Liftware — Parkinson’s-correcting spoons.
Hardening Android, Samsung Connivery, Scalable WebSockets, and Hardware Machine Learning
- Hardening Android for Security and Privacy — a brilliant project! prototype of a secure, full-featured, Android telecommunications device with full Tor support, individual application firewalling, true cell network baseband isolation, and optional ZRTP encrypted voice and video support. ZRTP does run over UDP which is not yet possible to send over Tor, but we are able to send SIP account login and call setup over Tor independently.
- The Great Smartphone War (Vanity Fair) — “I represented [the Swedish telecommunications company] Ericsson, and they couldn’t lie if their lives depended on it, and I represented Samsung and they couldn’t tell the truth if their lives depended on it.” That’s the most catching quote, but interesting to see Samsung’s patent strategy described as copying others, delaying the lawsuits, settling before judgement, and in the meanwhile ramping up their own innovation. Perhaps the other glory part is the description of Samsung employee shredding and eating incriminating documents while stalling lawyers out front. An excellent read.
- socketcluster — highly scalable realtime WebSockets based on Engine.io. They have screenshots of 100k messages/second on an 8-core EC2 m3.2xlarge instance.
- Machine Learning on a Board — everything good becomes hardware, whether in GPUs or specialist CPUs. This one has a “Machine Learning Co-Processor”. Interesting idea, to package up inputs and outputs with specialist CPU, but I wonder whether it’s a solution in search of a problem. (via Pete Warden)
Internet Broadband, Open Radio, Excel Formulae in JS, and Block Chains
- Observations of an Internet Middleman — Five of those congested peers are in the United States and one is in Europe. There are none in any other part of the world. All six are large Broadband consumer networks with a dominant or exclusive market share in their local market. In countries or markets where consumers have multiple Broadband choices (like the UK) there are no congested peers. Relevant as competition works for gigabit fibre to consumers.
- Open TX — open source firmware for RC radio transmitters. The firmware is highly configurable and brings much more features than found in traditional radios.
- Minimum Viable Block Chain — The block chain is agnostic to any “currency”. In fact, it can (and will) be adapted to power many other use cases. As a result, it pays to understand the how and the why behind the “minimum viable block chain”.
