unix hackers will get a kick out of this video of two teletype machines from the 1930s. a) /dev/tty means teletype b) control-G is BEL (rings Bell) c) CR and LF are mechanical commands that still exist in DOS. d) blue thyratron tube glow


my twitter stream is/was very local to my city. i dont know how to replicate that with toots. I want to send a message only to those people who live in my city. If I could group followers inside mastodon, that'd be helpful. Or if my followers list itself were a seperate service that I could manage and group and they'd show up anywhere I wanted. Google Circles was ahead of its time and also shot itself in the foot with no API.

I've attempted to explain the details of cross-chain atomic swap in this blog post. donp.org/blog/2018/12/05/atomi

What to expect at Hacker Beach:

* Hacking, not cracking
* FOSS creation and contribution galore (non-programmers explicitly welcome)
* Also get your day job done if you want/must
* Fantastic weather
* Outdoor activity options like e.g. hiking, kayaking, snorkeling, scuba-diving, mountain-biking. (Lots of us learned diving during past editions.)
* Explore the wider region, esp. before/after your time at the official location
* Whatever you want to make it. Hacker Beach is just people.

I finished Shatner's latest autobiography (yes there is more than one but this is the first one I've read). In the book there is a quote from somewhere else that goes its easy to spend too much time trying to be happy instead of being happy. Its stuck with me so far this week.

A QA engineer walks into a bar. Orders a beer. Orders 0 beers. Orders 99999999999 beers. Orders a lizard. Orders -1 beers. Orders a ueicbksjdhd. (from twitter)

One upside of the Google Music interface being not very good for discovering music (and perhaps no platforms are), is that I have to come up with band names myself. I enjoy lots of music but never payed too much attention to having particular music available. For instance, techno podcasts were a big source of music for a while. Now I'm having fun thinking of a band name that is famous but I probably dont know at all and just listen to an album of theirs. Today includes The Ramones.

The Blender project is posting new videos on their instance of peertube and the notices are showing up in my mastodon feed. The fediverse is pretty great.


the bitcoin cash fork happening today has two sides both with many megawatts of hashpower at their disposal. the changes in hashrate on each side is a tug-of-war played with electricity, silicon, and human organization (mining pools).

I recommend The Last Days of Night about the 1850s electrification of New York City and the legal battles between Edison and Westinghouse (and Tesla).


Just did a writeup on getting started with using LIDAR data and the geo-mapgen project to create a voxel world inside minetest.


cellphone based augmented reality is still a great idea. why doesnt a game like this exist?

This trailer for "Shadow Cities" is from *2010* and to my knowledge there isnt a game like it outside of the Niantic franchises.

publiclab.org does amazing work to foster environmental literacy and citizen science.

is there a mastodon/activitypub discovery/search site? the tag explorer site i know of is down. mastodon-tags-explorer.hcxp.co

seems like there is an opportunity for someone to build something interesting in that space.

1. add a query that is fast on your laptop
2. deploy query to production
3. freak out when page loads take 20sec and you dont know why
4. rollback
