Yes, I would consider HN as social media/networking site

Is there a name for oft-repeating content/post and the overall discussion on a given topic (dotfile management in this case) on HN?

I am not complaining about the repeat. It’s just that I find it very amusing to see different people kinda-sorta reinventing the wheel (and discussing the nuts and bolts) again.

We’re just looking at the manifestation of one of the hardest problems in software engineering - naming things.

There’s no one good answer. Instead we must design our system to be “soft” i.e. malleable - able to evolve as the world evolves.

Note that the design of the experiment needs to be able to disprove theory. That is to say if the results don’t match calculations then their theory is falsified and we make progress.

All of these incidents remind me of episodes from House MD. I swear they made one on this Antartica where House did a “zoom call”.

The airplane guy had more complications than ruptured lung but apparently he had just came out of scuba diving into the plane.

I don’t understand how an anti-proton can orbit a nucleus without annihilating into pure energy with a proton from the nucleus.

What am I missing here?

Honestly speaking I am really amazed by these researchers ability to separate and then “shove” an anti-proton in a Helium gas.

Don’t forget to commit your changes if you’re going to `reset --hard` later!

Not controversial at all!

Most linux distributions come with python installed. Anything more than invoking a binary and redirecting the output? Just write it in (pure) python I say!

Edit: by pure Python, I mean don’t require any `pip install`s

I get your sentiment but this is really exciting news in the chess community. A win after so many years!!

Vishy Sir during the end game commentary said that the engines say it’ll be a draw.

Where/which move did Ian make the mistake?

Anyways, hats off to everyone involved. Magnus, Ian, commenters, and the chess twitterati. What a game! ~8hrs!!!

New comment by wadkar in "SSH Tunneling Explained"

wadkar — Sun, 10 Oct 2021 18:15:54 +0000

I have read far too many ssh tunneling articles and all of them either forget about the bind address or just pretend that the only host that can be tunneled is localhost.

The fact is that ssh tunnels are bound to an interface on one side and the other can be any (reachable) host:port. So if example.com:1234 isn’t reachable from your host network, you can do a local port forward to example.com:1234 from an intermediary host that can reach example.com:1234

wadkar — Tue, 15 Jun 2021 15:38:22 +0000

I can’t make sense of this. Are you telling me that any Android user with “default” pixel setup will use my SSID for location tracking?

And that if my WiFi shouldn’t be part of Google’s (and Microsoft as well) data collection I need to suffix my SSID with _optout_nomap??

This has to be a joke. Any docs/refs/links?

Heck, even today it’s the polite way to communicate with drivers and maids. Don’t answer the call, but immediately call back and ask them if everything is ok. They won’t call you if it’s not urgent and important.

Personally, I learnt my bash by reading a lot of Gentoo EBUILD scripts and config files. I can recognize other Gentoo users just by how many curly braces and double quotes I see in a simple one liner.

The one resource that I have bookmarked decades ago and would highly recommend to get the ball rolling are the TLDP pages on bash:

https://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html

https://tldp.org/LDP/Bash-Beginners-Guide/html/index.html

https://tldp.org/LDP/abs/html/

Not certain if they’re up to date or error free but I really enjoy the style and tutorial/show by example nature of the TLDP

PoE is probably Power over Ethernet. With that you don’t have to worry about laying down electrical line to power the APs. The APs draw power from the Ethernet line itself

I believe the walrus operator `:=` was introduced in Python 3.8. So keep that it in mind.
