HPR2940: Better Social Media 05 - Mastodon
November 08, 2019 00:00 - 6.91 MBAs mentioned earlier, Diaspora was one of the earliest alternative, privacy-respecting social media platforms, but it was focused on being an alternative to Facebook (and it has done this fairly well).

Mastodon is a nice federated alternative to Twitter and a nicer place to be. https://www.zwilnik.com/?page_id=1034 Links: https://joinmastodon.org/ https://en.wikipedia.org/wiki/Identi.ca http://pump.io/ https://en.wikip...

HPR2938: Naming pets in space game
November 06, 2019 00:00 - 10.4 MBIntro In the two previous episodes we built a weighted list and used that to build markov chains. This time we’re going to use them to generate some names based on examples. I’m skipping over a lot of uninteresting code in this episode, concentrating only the parts that deal with names. Idea Person in game might hear scurrying sounds inside walls of their quarters. Then they have option of getting a cat, taming a rat or letting someone else deal with the problem.

October 29, 2019 00:00 - 25.9 MBThis episode is Part 10 of the Stardrifter role-playing game playtest. The series is composed of two playtest sessions, held earlier this year.

Playtesting is not the final step, but rather, just another stage. The construction of an RPG can be convoluted, and feedback from players is absolutely vital. It’s not...

October 25, 2019 00:00 - 7.74 MBI don’t know if Diaspora was the first of the alternatives to come along, but it was certainly the first I was aware of. It got a lot of attention for the college students who first put it together (and remember that Facebook was originally created by a college student, Mark Zuckerberg).

It still wouldn't boot even with the repaired filesystem, but I was able to mount the drive and copy her files to a USB drive. Links Blog post Howto: Repair/Fix MAC HFS+ Partition Using ...

Wikipedia states that “A Markov chain is a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event.” and that they’re named after the Russian mathematician Andrey Markov. Configuration We’re after generic system, hence parametrized data types. First part is Configuration a that lists possible startin...
