Send free emails from Heroku Updated +Created
Arghh, why so hard... tested 2021:
  • SendGrid: this one is the first one I got working on free tier!
  • Mailgun: the Heroku add-on creates a free plan. This is smaller than the flex plan and does not allow custom domains, and is not available when signing up on mailgun.com directly: help.mailgun.com/hc/en-us/articles/203068914-What-Are-the-Differences-Between-the-Free-and-Flex-Plans- And without custom domains you cannot send emails to anyone, only to people in the 5 manually whitelisted list, thus making this worthless. Also, gmail is not able to verify the DNS of the sandbox emails, and they go to spam.
    Mailgun does feel good otherwise if you are willing to pay. Their Heroku integration feels great, exposes everything you need on environment variables straight away.
  • CloudMailin: does not feel as well developed as Mailgun. More focus on receiving. Tried adding TXT xxx._domainkey.ourbigbook.com and CNAME mta.ourbigbook.com entires with custom domain to see if it works, took forever to find that page... www.cloudmailin.com/outbound/domains/xxx Domain verification requires a bit of human contact via email.
    They also don't document their Heroku usage well. The envvars generated on Heroku are useless, only to login on their web UI. The send username and password must be obtained on their confusing web ui.
Phaser.js Updated +Created
Likely the best JavaScript 2D game engine as of 2023.Uses Matter.js as a physics engine if enabled. There's also an alternative (in-house?) "arcade" engine: photonstorm.github.io/phaser3-docs/Phaser.Physics.Arcade.ArcadePhysics.html but it appears to be simpler/less robust (but also possibly faster).
TODO any 2D first person examples a bit like Ciro's 2D reinforcement learning games?
The examples are present under:
git clone https://github.com/photonstorm/phaser3-examples
but note that that repo is huge, about 4.5 GiB on local disk, as is has tons of assets.
The demos also include a Monaco-editor based sandbox mode where you can edit code directly on the web and see the game update which is a really sweet addition.

AGI research has become a taboo in the early 21st century Updated +Created
Due to the failures of earlier generations, which believed that would quickly achieve AGI, leading to the AI winters, 21st researchers have been very afraid of even trying it, rather going only for smaller subste problems like better neural network designs, at the risk of being considered a crank.
While there is fundamental value in such subset problems, the general view to the final goal is also very important, we will likely never reach AI without it.
This is voiced for example in Superintelligence by Nick Bostrom (2014) section "Opinions about the future of machine intelligence" which in turn quotes Nils Nilsson:
There may, however, be a residual cultural effect on the AI community of its earlier history that makes many mainstream researchers reluctant to align themselves with over-grand ambition. Thus Nils Nilsson, one of the old-timers in the field, complains that his present-day colleagues lack the boldness of spirit that propelled the pioneers of his own generation:
Concern for "respectability" has had, I think, a stultifying effect on some AI researchers. I hear them saying things like, "AI used to be criticized for its flossiness. Now that we have made solid progress, let us not risk losing our respectability." One result of this conservatism has been increased concentration on "weak AI" - the variety devoted to providing aids to human
thought - and away from "strong AI" - the variety that attempts to mechanize human-level intelligence
Nilsson’s sentiment has been echoed by several others of the founders, including Marvin Minsky, John McCarthy, and Patrick Winston.
Don't be a pussy, AI researchers!!!

Mitochondria have DNA because they need to be controlled individually Updated +Created
Basically, energy supply has to be modulated rather quickly, because we spend a lot sometimes, and very little other times.
Even not turning it off quickly enough is a problem, as it starts to generate free radicals which fuck you up.
If control came from the nucleus, it has no way to address different mitochondria. But it might be that only one of the mitochondria needs the change. If the nucleus tells all mitochondria to stop producing when only one is full, the others are going to say: "nope, I'm not full, continue producing!" and the one that need to stop will have its signal overriden by the others.
