I routinely use "load bearing" in conversations and writing, both seriously and ironically (like a "load bearing just" or "load bearing paint").. maybe I should stop.

The hydrogel textures (not maurten but naak, but close enough), for me, allow while racing to swallow a full 40g gel in half a second without feeling the sugary taste a lot, which is nice. Compared to thick syrup-like gels, it’s a way bette

Re : running relaxed, it is said that the real marathon is the training you put in, and the race itself should feel like a celebration. I am not anywhere near elite level but felt that for a lot of races. The hardships of the training enabl

Hi, I could send you the link but as outlined in the post, this specific mirror was very out of tolerance..

Sure ! Here are a few links : https://stellafane.org/stellafane-main/tm/index.html How to make a telescope, by Jean Texerau, which was the absolute bible of this field : https://rexresearch1.com/As

This one is a bit of a joke with my telescope making friends, but ticks all the boxes of what I consider a real telescope. You can actually buy 76mm entry-level telescopes, but they often have an unstable mount and bad optics. Starting at 1

Small mirrors with a very low F-ratio are also something that you need to grind yourself. I have a 6" f/2.8 telescope and a 8" f/3.5 hyperbolic + ross telescope, and both aren't commercially available while being sm

Absolutely, second hand is the most direct path to getting a telescope.

This is the first time I've seen a build of the ABSDBS in the wild, thanks for sharing ! Sadly an 8" f/4 mirror has a very narrow range of acceptable optical quality :/. It's too bad you ended up with a bad one. May

I will correct the article, I've found great λ/6 or better spheres on Ali, but have yet to get a well corrected mirror. But starting from a λ/6 sphere instead of a flat glass blank saves so much time ! For this specific mirro

There is quite a vibrant community of young people grinding mirrors, it just has displaced to Discord. The "Observational astronomy" discord server has a lot of late-teenagers and young adults grinding. Our french Astro-FR server

We buy pre-dug mirrors on Ali to refigure them, or dig and figure our own all the time. See Ali as a supplier of prepolished blanks :) . The l/6 I mentioned in the post are l/6 spheres, so they also need figuring.

Rik's monolithic Cassegrains are the perfect example of the blend of amateur and high-end professionnal work in astronomical optics, thanks for linking it ! His amateur work is incredible, like this 16" CDK : https://ww

No, but that should be quite straightforward to add with Astro, I will check that. Edit : it seems that I now do have one : https://lucassifoni.info/blog/tag/astronomy/rss.xml I am not an RSS user myself

Your comment brings me back to my first mirror making adventure, I was absolutely overwhelmed by the jargon and acronyms used by the mirror making community... a few years later I internalized it and use it as if it was common knowledge. I

To add to this topic, people who do not know about erlang's hot code loading should watch this talk : https://www.youtube.com/watch?v=pQ0CvjAJXz4 A multi-DC running cluster where parts are progressively swapped at runt

Personal habit, honestly. If I had to re-start I'd probably pick React today, but the Vue switch to a composition API make me like it enough when I was thinking of switching. What I'm truly rooting for is a non-limited Elm.

I'm not using this to update the app itself - which is a docker container that gets updated when I push a new version. I'm simply using the BEAM's code loading capabilities to add client-specific parts to the app while it is

Author here, thanks for sharing ! Happy to answer any questions. I think the article outlines it, but I'm at very low scale, with custom development for every client. I mostly build mini-figmas, collaborative or not, that automate spec

Still working on Alzo [1], my services startup for french architecture companies. These days I spend most of my time writing client-specific apps [2] that are hot loaded on demand into my Elixir monolith. So far I like this architecture a l
