Why People With Brain Implants Are Afraid to Go Through Automatic Doors
In 2009, Gary Olhoeft walked into a Best Buy to buy some DVDs. He walked out with his whole body twitching and convulsing. Olhoeft has a brain implant, tiny bits of microelectronic circuitry that deliver electrical impulses to his motor cortex in order to control the debilitating tremors he suffers as a symptom of Parkinson’s disease. It had been working fine. So, what happened when he passed through those double wide doors into consumer electronics paradise? He thinks the theft-prevention system interfered with his implant and turned it off.

Olhoeft’s experience isn’t unique. According to the Food and Drug Administration’s MAUDE database of medical device reports, over the past five years there have been at least 374 cases where electromagnetic interference was reportedly a factor in an injury involving medical devices including neural implants, pacemakers and insulin pumps. In those reports, people detailed experiencing problems with their devices when going through airport security, using massagers or simply being near electrical sources like microwaves, cordless drills or “church sound boards.”

RIPE Atlas Probes
Interesting! We discussed similar ideas in $prevjob, good to see one hitting production globally.
RIPE Atlas probes form the backbone of the RIPE Atlas infrastructure. Volunteers all over the world host these small hardware devices that actively measure Internet connectivity through ping, traceroute, DNS, SSL/TLS, NTP and HTTP measurements. This data is collected and aggregated by the RIPE NCC, which makes the data publicly available. Network operators, engineers, researchers and even home users have used this data for a wide range of purposes, from investigating network outages to DNS anycasting to testing IPv6 connectivity.

Anyone can apply to host a RIPE Atlas probe. If your application is successful (based on your location), we will ship you a probe free of charge. Hosts simply need to plug their probe into their home (or other) network.

Probes are USB-powered and are connected to an Ethernet port on the host’s router or switch. They then automatically and continuously perform active measurements about the Internet’s connectivity, and this data is sent to the RIPE NCC, where it is aggregated and made publicly available. We also use this data to create several Internet maps and data visualisations. [....]

The hardware of the first and second generation probes is a Lantronix XPort Pro module with custom powering and housing built around it. The third generation probe is a modified TP-Link wireless router (model TL-MR 3020) with a small USB thumb drive in it, but this probe does not support WiFi.

AWS Greengrass
AWS Greengrass is software that lets you run local compute, messaging & data caching for connected devices in a secure way. With AWS Greengrass, connected devices can run AWS Lambda functions, keep device data in sync, and communicate with other devices securely – even when not connected to the Internet. Using AWS Lambda, Greengrass ensures your IoT devices can respond quickly to local events, operate with intermittent connections, and minimize the cost of transmitting IoT data to the cloud.

AWS Greengrass seamlessly extends AWS to devices so they can act locally on the data they generate, while still using the cloud for management, analytics, and durable storage. With Greengrass, you can use familiar languages and programming models to create and test your device software in the cloud, and then deploy it to your devices. AWS Greengrass can be programmed to filter device data and only transmit necessary information back to the cloud. AWS Greengrass authenticates and encrypts device data at all points of connection using AWS IoT’s security and access management capabilities. This way data is never exchanged between devices when they communicate with each other and the cloud without proven identity.

mjg59 | Fixing the IoT isn't going to be easy
We can't easily fix the already broken devices, we can't easily stop more broken devices from being shipped and we can't easily guarantee that we can fix future devices that end up broken. The only solution I see working at all is to require ISPs to cut people off, and that's going to involve a great deal of pain. The harsh reality is that this is almost certainly just the tip of the iceberg, and things are going to get much worse before they get any better.

brixsystem
This conceptual collection consists of eight 6:1 scale versions of classic LEGO bricks, each fully functional in one way or the other. Including eight matching photo montages, a homage to the box cover art for the classic "Legoland Space" line. Hultén - "Like most people, I was raised by Lego. For this project, I chose to work with a set of decorated bricks from the iconic 79-87 "Legoland Space" line. These were bricks that would trigger my imagination as a child. 25 years have passed, and they still trigger"

/dev/full - Wikipedia, the free encyclopedia
This is handy!

'In Linux, /dev/full or the always full device[1][2] is a special file that always returns the error code ENOSPC (meaning "No space left on device") on writing, and provides an infinite number of null characters to any process that reads from it (similar to /dev/zero). This device is usually used when testing the behaviour of a program when it encounters a "disk full" error.'

The $12 Gongkai Phone
Welcome to the Galapagos of Chinese “open” source. I call it “gongkai” (公开). Gongkai is the transliteration of “open” as applied to “open source”. I feel it deserves a term of its own, as the phenomenon has grown beyond the so-called “shanzhai” (山寨) and is becoming a self-sustaining innovation ecosystem of its own.

Just as the Galapagos Islands is a unique biological ecosystem evolved in the absence of continental species, gongkai is a unique innovation ecosystem evolved with little western influence, thanks to political, language, and cultural isolation.

Of course, just as the Galapagos was seeded by hardy species that found their way to the islands, gongkai was also seeded by hardy ideas that came from the west. These ideas fell on the fertile minds of the Pearl River delta, took root, and are evolving. Significantly, gongkai isn’t a totally lawless free-for-all. It’s a network of ideas, spread peer-to-peer, with certain rules to enforce sharing and to prevent leeching. It’s very different from Western IP concepts, but I’m trying to have an open mind about it.

Copying block devices between machines
a very hairy hack to perform a block-level rsync-like "send just the changes" algorithm between two very large files (think /dev/sda block devices).  Crazy, but it'd work alright!
