fiveg··on Exercise intensity influences body composition in healthy older adults (2025)
One thing that I think gets looked past in studies like this is the “noob gains” effect. These participants are healthy adults but not highly trained. It’s pretty well known, in cycling at least, that hard interval training is super effective for untrained people or people coming back from a break, but the gains plateau relatively quickly, and the stress of doing this kind of work is hard to sustain for long periods. Another notable thing is that they are doing 45 minute sessions regardless of intensity, in the real world it’s common for lower intensity sessions to be longer, and for those sessions to be a foundation on which higher intensity sessions are carefully added.
fiveg··on Ask HN: Are people in tech inside an AI echo chamber?
You might be thinking of Blindsight by Peter Watts. Great book.
fiveg··on Covid Killed the Raspberry Pi
Which one(s) would you suggest for little DIY things like home automation, print servers, etc?

Beautifully sampled in the intro to this mix by Nicholas Jaar: https://www.youtube.com/watch?v=2h1h1JdaWGk
fiveg··on Is Haskell really the language of geniuses and academia? (2019)
This a pretty hot take. I'm in the early stages of learning go. So far I like it a lot, but I come from the perspective of a data person who only knows python. I want to learn a compiled language, what would you suggest instead?
fiveg··on Ask HN: Why are delivery apps so expensive?
Well you're adding two parties to the transaction. If you go to McDonald's you just have to pay McDonald's. If you use a delivery app you also have to pay the delivery person and the app.
fiveg··on Ask HN: What's your note-taking methodology?
I keep my life notes in plain text in a directory called "notes", usually formatted with markdown. I rarely render the markdown but I still find it useful for structuring my notes. I also incorporate a very lean take on getting things done (GTD). I host it on github and sync it between devices with syncthing.

My main requirement is that it should be very easy to start writing the note. This means not many decisions to make first (deeply nested directories or tags), and not being bound to a certain application or having an internet connection.

Plain text is great because it's small, portable, and I like being able to use grep against my note directory to find things.

basic structure:

- One file per year for a basic daily log in (log/2022.md) this is where I do at least half of my notetaking and journaling.

- a few GTD files in the top level, in.md, next.md, somedaymaybe.md

- a projects directory, prj/, which has a sub directory for various projects, these can be small stuff that take weeks, or longer things

- a list directory, lst/, which has lists of thing, example: books to read, groceries to buy, etc.

- a reference directory, ref/, for storing things that I'd like to remember but aren't active projects or notes that I expect to add to often (those should be projects or just go in log/), example: a recipe

I've been doing this for a few months now and I am liking it quite a bit and expect to stick with it. The biggest headache is getting syncthing to work with ios so that I can reliably have my notes on my phone, open to suggestions on that.

fiveg··on Want to start hacking?
I have thought about this actually. It sounds really interesting but at $1500 for 90 days of access I'll need to make sure to find a time when I don't have much on my plate for 90 days. How much time per week do you feel you need to dedicate to it? Are you enjoying the process?
fiveg··on Want to start hacking?
I'm in a very similar position. Right now I'm working on tryhackme.com's junior pentester learning path. It's OK, but I think I'd be more excited to find a project or goal to focus on instead of a shallow overview of lots of topics (even though the context feels valuable). I'll finish the course, but I think I'll be done with tryhackme after that and go back to looking for something more specific the dive in to.
