coggs··on My experiment living in a tent in Hong Kong's jungle
I lived and worked on the HKUST campus in the 90's.. Very picturesque. Surrounding coastline very rugged. He picked a good spot. No egress there at the bottom of the hill. Fun fact: He camped just below the historic location of Shaw Studios, who popularized the Kung Fu movie genre

coggs··on Abandoned villages of Hong Kong
I lived in HK in the 90's at the HK University of Science and Technology. It's out in the New Territories, surrounded by small villages and otherwise mostly undeveloped dense, low-lying scrub. We'd hike in the country parks and it could be surreal; Remnants of abandoned villages like in the article. Feral dogs like in the article. We had some Hakka ladies take us on their boat out to I think it was Pak Sha Chau where there was a small pathetic abandoned amusement park. Also there was a larger island with an original refugee camp from the Vietnamese boat people era. Now I think it is a golf course.. Great memories
coggs··on Sudo for Windows
I guess if we were on a conquest for universal adoption we can now say we've succeeded.. <pinches self>
coggs··on The first stable release of a memory safe sudo implementation
Hackaday interviewed me about the origin story - https://www.youtube.com/watch?v=LaAwl3HN5ds&ab_channel=HACKA...
coggs··on The first stable release of a memory safe sudo implementation
As one of the original creators of sudo (https://en.wikipedia.org/wiki/Sudo) I've witnessed it getting nearly totally rewritten and then incrementally bug-fixed over the last 43 years. It must take the prize for the UNIX command most highly-scrutinized for security flaws. Flaws which have been identified and fixed.

Thousands of developers and security experts have gone over it. So part of me wonders - how is it possible for a single dev team to totally reimplement it without unknowingly introducing at least a bug or two? Is there something to this Rust language which magically eliminates all chances of any bug being introduced?

coggs··on Pick-and-place machine
I own a Manncorp MC-400 Pick and Place. Surprised wiki does not mention Manncorp or Autotronic or Quad. Seen many inidie DIY PnP projects come and go. The latest generation of low-end Chinese PnPs like Neoden have seen increased popularity for personal and small batch use.
coggs··on Tell HN: Digikey has 1822 Pi4 8GB and 3793 1GB in stock
I've also switched over to OrangePi. Using the OrangePi Zero LTS in a commercial product. It has FCC emissions compliance. That said, The RasPi community is at least 2 or 3 orders of magnitude larger, so if you get stuck on a weird problem you are more likely to find an answer for a RasPi than an Orange Pi.
coggs··on Raspberry Pi production rate rising to a million a month
In the mean-time there are now more lower cost, in-stock alternatives to the RPi than ever such at the OrangePi.
coggs··on I Made a Wemos D1 Mini Dev Board
WeMos D1 Mini FTW. So many ESP8266 libraries out there now.
coggs··on After self-hosting my email for twenty-three years I have thrown in the towel
After 30 years running my own MTA I also gave up and moved to fastmail.
coggs··on Introduction to I²C and SPI protocols
Good article. There was a recent kickstarter for something called 'i2c and spi education shield' with some great tutorials and hw also..
