Lambda

Can someone spell this one out for me? I can’t remember any of their names :/

I grew up in Durham region (Bowmanville specifically). This absolutely checks out. Luckily some of Bowmanville is somewhat walkable-ish (about all you can hope for in Durham), probably because of the sizeable Dutch immigrant population of old Bowmanville I’d guess?

I’ve never found a good link, and I’m not certain that I know best, but I can try to explain it to you.

First: an understanding of the Pauli exclusion principle. Often people ask “Why can’t there be 3 electrons in that orbital, there’s plenty of space?” The thing is that the electrons are completely¹ defined by just 4 numbers: spin (±½), shell (positive integer), subshell (integer from 0 to shell-1) and magnetic (integer form -subshell to +subshell). Why there can’t be more than 2 electrons in the 1st shell is that you can chose spin from (±½), shell is 1, subshell has to be 0, magnetic has to be 0. Its like asking “Why can’t there be 3 integers between 0 and 3, there’s plenty of space?” and the answer is that whatever integer you come up with will be one of the 2 already known (1, 2).

Similarly, as I understand it, the fundamental laws of physics don’t distinguish between “things” closer than 1 Planck length apart. That doesn’t necessarily mean that the universe operates on a 1 Planck length grid, just that any two “things” separated by less than a Planck length are indistinguishable from one new “thing” with different properties.

I’m fairly confident in the PEP description, the Planck length one I’m less 100% sure about, but its how I understand it at least.

¹assuming a universe comprised of only a single hydrogen atom, otherwise the states of everything else in the universe can perterb the state functions and things can get messy, but usually not enough to merge shells.

I think self hosting the proxy with the services at hobbyist scale mitigates most of the security risks. The single point of failure risk is another matter. I once had to effectively reverse-hack my services by uploading a Jenkins test job through an existing java project to regain access. Ever since then, I maintain a separate ddns address that’s just used for emergency ssh access.

I’m the bottom, so is my wife. Only difference is she does it DURING the movie. It can be pretty annoying, hard to get used to.

I believe it stands for Free/Libre Open Source Software. I think the idea is to explicitly indicate both free as in beer and free as in speech. However, to me it just sounds like throwing in a romance term for the sake of it. But maybe I’m just ill versed on the whole free/libre divide?

I’m one of the very rare people that have the gene that makes cilantro taste like soap, but likes it. I blame the soap flavoured gum I had as a kid here in Canada.

So maybe save a little soaplantro for those that want it ;)

Thank you. Clear, easily understood explanations of questions I always wondered. 👍🏼

Whenever I see this image I always wonder 2 things:

1. What makes hemoglobin more efficient?
2. Why do we even need these fancy molecules to transport oxygen? Can’t we produce some kind of biological ampule that holds some pure O2 for consumption by the various processes that need it? We have dedicated organelle structures for similar tasks (i.e. mitochondria)

Apparently it’s not even really all that stable, so that whole container would rapidly decompose into probably carbon dioxide (CO2) and a bunch of pure carbon (think charcoal). At least that’s my hunch. There is a Wikipedia article on the stuff, but it’s pretty short, since it’s a pretty unusual chemical (https://en.m.wikipedia.org/wiki/Dicarbon_monoxide ).

CO2 is of course extremely common. I’d love to see what a chemist can describe about a bottle of C2O though!

Ada, hands down. Every time I go to learn Rust I’m disappointed by the lack of safety. I get that it’s miles ahead of C++, but that’s not much. I get that it strikes a much better balance than Ada (it’s not too hard to get it to compile) but it still leaves a lot to be desired in terms of safe interfacing. Plus it’s memory model is more complicated than it needs to be (though Ada’s secondary stack takes some getting used to).

I wonder if any other Ada devs have experience with rust and can make a better comparison?

I use fslint myself. Basically a linter for files :)

Sadly front end, like “High Level” is a very relative term. For example, in compiler design, the bit that parses code is called the “front end” since the “back end” is what emits machine code. I think that’s what they mean here, the “front end” that understands D3D8 code has been added, presumably there is also a “back end” that converts the parsed/analyzed D3D8 code into valid opcodes for consumption by GPU/CPUs.

In the other direction, a UI/UX is sometimes called a “back end” when it is part of a more complex embedded project where physical controls are the “front end”.

I still use Ada daily for my personal projects after having used it at work. I find it compliments my thinking patterns well. My only gripe with it is that they ate too much of their own dog food at AdaCore and now it can be hard to install Ada and gprbuild (due to a circular dependency). Plus gprc stole libgpr and broke some stuff too.

That would be an excellent idea. But I feel like an even broader community should be created. Like a generic book club, but for code bases! Could even have a small handful of different code bases on the go at a time. I’d love to get to know lemmy’s, but also e.g. neovim, or even unciv :)

Maybe one day it could even start tackling Moby Dick!

My question when I see responses like this is: what genuinely useful new safety features have been added since Ada? It’s ancient and has distinct types, borrow checking (via limited types), range types, and even fixed point types. I’ve always wondered what niche Rust is targeting that Ada hasn’t occupied already. It feels like devs decided that safety was important, c/c++ are too unsafe, need a new language; without ever having looked to see if such a language exists?

All praise our lord and saviour git rebase -i!

Answering both: dial image for reference to what the “modes” are, and my dial is gross. Plus that was the best image I could find describing it, but had trouble getting a clean download. Google images can suck that way. If you get me a clean link, I’d update the post.

In case anyone wants the real meanings: I am not a lawyer, read the f***ing manual, bank of america.

Beej’s guides are absolute classics. The networking guide is also amazing. Definitely worth the read.
