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.


I've read a looot of physiology studies about running, and the same dynamics hold true there. This is a flaw (IMO) of of the whole "Norwegian 4x4 protocol" you hear parroted around by biohacker/longevity influencer online, of course with 0 nuance or context of the underlying study and its limitations


This study followed everyone for 6 months so they probably got past that factor.


I doubt it. In my experience (at least when it comes to lifting), newbie gains last at least a year. Good chance that if they've been untrained all their life (or the majority of it) that phase is gonna last a real long time.


A year of continuous gains for a 72 year old? I highly doubt it. For a skinnyfat 20 year old, sure.


> I highly doubt it.

Not a very convincing discussion point without some support.


I stand corrected then.

This is 100% experience with both cycling and running, and something I worked out on my own early on, prior to the advent of smartphones and even talking to anyone who knew anything.

I enjoy sprinting, both running and cycling, but it’s mostly something I do to regain my endurance ability after a break. Two two weeks of high intensity interval training, and then I’m able to sustain moderate intensity jogging for 30+ plus again, or an hour cycling.


You might be thinking of Blindsight by Peter Watts. Great book.


Which one(s) would you suggest for little DIY things like home automation, print servers, etc?


If you want a true SoC because it's tiny and cute? Try a TI Sitara (BeagleBone, etc). The new BeaglePlay is really nice for $98.

If you need a home automation/print server? Get a $40 used Xeon workstation on eBay.


I don't know much about RPI alternatives, but those seem to either cost a lot more (BeaglePlay) or they seem to be much larger and with worse power consumption (used Xeon workstation)?


Then you're stuck. If you want to wait for the cheap subsidized part then it might be a while. Maybe forever in the case of the original Broadcom SoC. Beaglebone Black is ~$50 if price is really the problem. What's your objective here?


ESP32-S3-DevKitC-1 v1.1 is excellent. It's got multipurpose GPIO pins that can be used for input, output, ADC, touchscreen, etc., and it's got wi-fi and BLE. Easily programmed with the Arduino IDE. It's an MCU, not a single board computer. If you really need a Linux environment then Orange Pi has a lot of SBC models available. For those I use Armbian, which is optimized for SBC use.

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?


Haskell, Idris or Rust! I share the largely negative opinion of Go.

(my background is mostly python, R, javascript, clojure)


Rust.


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.


Well you’re really adding one party. They raise the price a little on the items, maybe a service fee. Fees. Because the food can’t deliver itself. (This is for the best.) Underhanded approach, but not insane reasoning.

Unfortunately… after baking in some income for the extra party, the delivery service…Well, said party wants to shift the burden of compensating empl… contractors to you. Through a tip! That’s fun. You can show your… appreciation. For them doing their job. Super motivating for drivers. Especially when everyone tips well.

Oh…

They brought the third party. Didn’t have to.

Could it be two parties? Sure. Pizza places, all you have to pay are the pizza place. And the driver they also didn’t wish to compensate fairly. But not all restaurants deliver.


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.


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.


It’s a little expensive but have you checked out the OSCP cert? It’s the only certificate in tech that I think is almost unanimously accepted as a decent one as it’s so practical. That might help give you a goal to keep learning? I’m going through it myself at the moment.


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?


They’ve changed this recently actually, its $799 for 12 months of lab access and some entry level certs. I signed up for this and will pay the extra for the OSCP once I’m ready!
