media archaeology lab<p>hey, London friends - </p><p><span class="h-card" translate="no"><a href="https://mastodon.social/@anmeisel" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>anmeisel</span></a></span> is getting a London-based <a href="https://post.lurk.org/tags/permacomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>permacomputing</span></a> club going. </p><p>from Ana: </p><p>Here's the event sign-up for the 7th of April with more information: <a href="https://www.eventbrite.co.uk/e/permacomputing-club-tickets-1290371077629?aff=oddtdtcreator" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">eventbrite.co.uk/e/permacomput</span><span class="invisible">ing-club-tickets-1290371077629?aff=oddtdtcreator</span></a></p><p>The first session requires an RSVP to help estimate attendance. For all following sessions, people are welcome to join on a drop-in basis. It'll happen every Monday at SET Social, 6:30 pm.</p>

Mullana<p>Hey <a href="https://chaos.social/tags/permacomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>permacomputing</span></a> people!<br>Would any of you like to share photos of your setups?

I'm sorry to tell you all that they got me.

I am currently rehabbing an old laptop to become a ProxMox server.

Some friends started a #selfhosting club/class facilitated by a former colleague who often works as a SysAdmin.

Realized I had this 2017 HP Laptop that had upgradeable ram and ssd ports. So some new parts make this dinky little laptop into a nice little custom server.

Still not sure how I'll put it to use, but Jellyfin and PhotoPrism for sure!

Via the @ataripodcast: in a 25-minute video, Jean Michel Sellier, Research Assistant Professor at Purdue University, demonstrates the use of an #Atari800XL to train a neural network using a genetic algorithm instead of the memory-hungry technique of gradient descent.

I've had a soft spot for Artificial Life for a long time. During the last AI Winter in the mid 1990s, I was spurred to get back into education and onto a career in commercial software development by Stephen Levy's book "Artificial Life: The Quest for a New Creation". I loved that Artificial Life researchers borrowed well-understood mechanisms from genetics and implemented them in software to converge iteratively on solutions, in contrast to AI research, which was attempting to build models of categories which were not understood at all (and largely still aren't) - intelligence (whatever that is) and perception.

In subsequent years I wondered why I wasn't hearing any hype about Artificial Life; it turns out practitioners have been quietly getting on with solving problems using the technique. Meanwhile, yet again, AI boosters have blustered their way into the consciousness with another round of overcooked hype.

The Stephen Levy book is still worth a read, if you can find it. (IIRC Danny Hillis and the Connection Machine folks get a mention too.)

(I don't know if any of the genetic algorithm folks turned out to be supporters of eugenics, as many of the current crop of AI boosters seem to be.)

Hackaday · Genetic Algorithm Runs On Atari 800 XLFor the last few years or so, the story in the artificial intelligence that was accepted without question was that all of the big names in the field needed more compute, more resources, more energy…

@lumecolca there is a subset of the Internet that likes to keep web pages simple. Whether JavaScript should be used remains a contentious topic, personally I believe anything that won’t run well on a 30-year-old computer is not #permacomputing .
