I was looking to learn at least the basics of the ARM processor and found some wondeful references and tutorials to ARM assembly language. The one thing left was how device I/O works. Here’s a simple device driver code project for Linux on ARM in, of course, the Raspberry Pi.
InterPlanetary File System
“IPFS is a distributed file system that seeks to connect all computing devices with the same system of files. In some ways, this is similar to the original aims of the Web, but IPFS is actually more similar to a single bittorrent swarm exchanging git objects.”
Flight Problems
Iain Thomson on “This Week in Tech” listed an amusing flight problem you don’t want to experience: “A reduction in the number of wings.”
Deep Seated Container Vulnerability
“A vulnerability in container operations has been brought to light by Docker and other parties and illustrates why lack of multiple years of experience with containers makes some implementers cautious. A command to execute the RunC part of the Linux kernel under rare but exploitable circumstances can result in a container process getting a chance to inspect file descriptors on the host.”
Danger: Effective Gmail Phishing
“Wide Impact: Highly Effective Gmail Phishing Technique Being Exploited by Mark Maunder”
This is pretty insidious. You get a message from someome you know. It has an attachment. You try to open it but up pops a Gmail login page asking you to enter your password again for security. That Gmail login page is fake and your password is stolen as soon as you type it in.

Flight Gear
I just recently learned from Andy Ihnatko on “Macbreak Weekly” that there is an open source flight simulator called “Flight Gear.” It seems quite capable with many add-ons provided.
USENIX Computing Systems
For many years I received the USENIX “Computing Systems” journal and recently, when doing I search, I discovered the entire archive is on-line.
NASA Made a Fundamental Mistake
On an ISS Power supply.
“The ISS is currently home to…four 14,000-pound payload-holders called ExPRESS Logistics Carriers. Experiments from Earth like the laser-communicator OPALS fly up to Station and Lego-attach to these carriers, which provide them with a place to stay and, just as importantly, the electrical power and data links they need to do their jobs. But since 2013, scientists sending up payloads have had trouble with the on-orbit utility grid.”
