fyhn commented on Launch a Debugging Terminal into GitHub Actions blog.gripdev.xyz/2026/01/... · Posted by u/martinpeck

That the entire ecosystem seems to have moved to GitHub Actions is such a loss for productivity. I remember when CircleCI first launched, and you could "Rebuild with SSH" which gave you a bash command to connect to the running instance whenever you wanted, was such a no-brainer, and I'm sure why many of us ended up using CircleCI for years. Eventually CircleCI became too expensive, but I still thought that if other services learnt anything from CircleCI, it would be this single feature, because of the amount of hours it saved thousands of developers.

Lo and behold, when GitHub Actions first launched, that feature was nowhere to be seen, and I knew from that moment on that betting on GitHub Actions would be a mistake, if they didn't launch with such a table-stakes feature. Seems still Microsoft didn't get their thumb out, and wasting countless developer's time with this, sad state of affairs.

Thank you pbiggar for the time we got with CircleCI :) Here's to hoping we'll have CircleCI.V2 appearing at some point in the future, I just know it involves DAGs and "Rebuild with SSH" somehow :)

I've gotten used to this essential feature too via Semaphore CI, and I just can't stand not being able to SSH into a GitHub Action. Debugging is so slow.

Oh well. The whole thing has already been reverse engineered. Look up Loop or Trio or OpenAPS. Diabetic companies like Insulet have been very lax when it’s come to the hacking of their devices. This isn’t really that big a deal. What we need right now is help REing the Omnipod 5

Not all though, I've been looking at Minimed pump reverse engineering (which would be just reading glucose data, not controlling the pump), and that's not solved yet, at least not for the 780G. But I hope it will be, and perhaps I'll be able to contribute.

I've always wanted to make a two-factor authentication device that has a camera, QR reader, and an e-ink screen for listing the codes that otherwise does nothing else. but ive always been a bit limited because I don't really know where to get started making hardware. but i feel like 2-factor authentication is the number one thing preventing me from getting rid of my smartphone which is kind of silly because why do i need some massive super computer in my pocket (at least from the perspective of the 1980s) to have an alternating cypher to login to websites on my laptop.

Some password managers like 1Password can do the two-factor stuff for you, so you don't have to pull out your phone. On the fully supported pages it'll just autofill your username, main password, and one-time password.

The only app I have that I actually like. It's great.

Those of you who use ROS in production, do y'all use ROS 1 or 2? Do you maintain your own fork? I'm curious how people do this, with the upcoming Noetic deprecation.

I've been fiddling a lot with getting my CGM glucose data on a smartwatch, in a way that I like, recently. I'm in the middle of a small series of posts on my silly blog here: https://fyhn.lol/blog/glucose-watch/

I love the font. Maybe particularly because it's kind of big, so you can see the details. It seems to be EB Garamond: https://en.wikipedia.org/wiki/EB_Garamond

For some background - I'm a T1D working on a search engine and conversational interface for integrating a bunch of new data sources and models into metabolic decision making: https://replica.health. I've also been a user of and worked on various open source artificial pancreas systems through the years, and am currently on Loop.

>I would have thought by now they'd have hacked 2 patch-pump AIDs to work simultaneously.

As you pointed out, the problem is not really hardware. It could technically be done in a straightforward way using two independently controlled insulin pumps, but the complexity and risk of the whole operation goes way up if you are taking way more insulin. Taking a bunch of insulin and glucagon at the same time is not necessarily a great idea either - they don't just annihilate each other without consequence and you could end up with secondary effects like gaining a bunch of weight.

>Because this feels like a holy grail / functional cure

Unfortunately it is not; even dual hormone systems have problems keeping up w/ the kinetics of glucose absorption and to address this there is also research into tri-hormonal systems, w/ amylin as the third hormone. In any case you will still need some a-priori info about meals and planned activities, though less so than with a single hormone system. Integration of exogenous data sources to provide this info to the APS is what we are working on at Replica.

Also, hate to be the bearer of bad news but beta bionics has shelved their dual hormone ambitions for now; their prototype device soon to be released is insulin-only. On the bright side there is a small Dutch company whose tech predates beta-bionics. They sell a dual hormone device and will give it to you for a ton of $ (and probably have you sign a bunch of waivers): https://www.inredadiabetic.nl/en/discover-the-ap/

This is very interesting, and I (T1D) would like to learn more. However, the e-mail signup doesn't work for me. ("Oops! Something went wrong while submitting the form.")

fyhn commented on Ask HN: What brand of laptop do you use? · Posted by u/rhaer

fyhn · 3 years ago

Home: A 13-inch Asus Zenbook from 2014 (UX32LN) now running Ubuntu (MATE) 22.04. It's still good!

Work: A recent 13-inch Dell XPS that shipped with Ubuntu 22.04. It's also great, but the function key row has been replaced with touch buttons which is not good at all (including the escape and delete keys).

Work, previously: A 13-inch Dell Latitude from 2017. I originally ran 16.04 on it, then 18.04 until the above replaced it. Worked very well. Had every port you can wish for, including ethernet. Eventually the battery swelled and the keyboard stopped working.
