Yup it seems crazy to me how deep insights one needs to have to be able to, say, connect the dots between compression and machine learning. And now it looks to me like he has done a lot of the foundational work in these fields. Super cool stuff

Too lazy to check, but is this the Rivest from the RSA algorithm?

Like you said, there's a metric ton of steps involved in the overall process, and our understanding of each of these 'levels' of organization varies quite a bit. Closest to my personal expertise is the sub-cellular and cellular level, for which I would refer you books or papers in developmental biology, developmental genetics, and epigenetics. I can give you a couple bloopers to get you excited though:

When it comes to deciding where different organs will form (again, from a sub-cellular level), it essentially starts from a concentration gradient of certain proteins/chemicals inside the zygotic cell. This gradient then determines the level of activation of other proteins, each level then leading to different biochemical cascades which, once more cells have formed from the zygote, determine which organ systems will come from them. Messing around with this concentration gradient can, thus, dramatically affect an organism's development, leading to, for example, a body with just 'left' organs on both halves, just 'top' organs on both halves, missing an entire organ system (like circulatory system and heart) and so on.

A more or less similar process occurs to determine the shape of organs. As a simple example, when some animals with regenerative capabilities (like axolotls) lose a limb, they are able to regrow the limb to the exact same length as before. Turns out, each cell on the periphery of their limb has a certain concentration of receptor proteins on its surface, which acts as a molecular 'signature' of that cell's position in the limb. These signatures provide information on how far to grow the limb for regeneration, and some chemicals, lile retinol, can even override these signatures and fool the organism's body into regrowing the limb from scratch on top of the place of regeneration.

I hope these examples give you an introduction to the mechanisms involved. There's obviously a lot more involved, so I would again highly recommend textbooks and research papers if you're interested.

Last I checked (which was some time ago), pandoc-bin doesn't require the haskell dependencies. I saved quite some installation time (and screen space during installation) by switching.

As someone who is often unable to even enjoy soda because it immediately starts bubbling up and only remains as a sugary liquid by the time it reaches the esophagus, I guess I can't replicate your observations. Also, I guess I need more water in my mouth before I can let Jesus into it (for a more pleasant experience for both of us)

If only it worked; the mentos would start disintegrating by your saliva and the coke would already form bubbles as soon as it enters your mouth thanks to the rough surface inside 🤓

IIRC it doesn't; that has caused me pain so many times when trying to generate fractional range

[-] goddard_guryon@sopuli.xyz 10 points 10 months ago

That won't work tho, you need to make it sys.maxsize//2 to coerce the output into int form

That may be exactly what I need when searching for some highly technical problem lol

Huh I didn't notice that. That does sound a bit weird :/

This is not an ad BTW, I literally stumbled upon it a few minutes ago. From what I can gather, however, this is a [DIY-ish] search engine that solely searches on text (no other forms of media, such as, ... idk hypertext maybe), which allows users to have more control over queries (like including and excluding terms). I suppose this would prune out most of the modern websites, but I guess some of y'all would prefer that option anyway. Has anyone else tried it out? I'm genuinely curious about more opinions on this

Indeed, an integer is divisible by 3 if and only if the sum of its digits is divisible by 3.

For proof, take the polynomial representation of an integer n = a_0 * 10^k + a_1 * 10^{k-1} + ... + a_k * 1. Note that 10 mod 3 = 1, which means that 10^i mod 3 = (10 mod 3)^i = 1. This makes all powers of 10 = 1 and you're left with n = a_0 + a_1 + ... + a_k. Thus, n is divisible by 3 iff a_0 + a_1 + ... + a_k is. Also note that iff answers your question then; all multiples of 3 have to, by definition, have digits whose sum is a multiple of 3

For Meet, I'd also suggest Jitsi. For Drive, I'd recommend giving cryptpad.fr a shot; that seems to be the closest to Drive's file editing capabilities.

I've been following this community for some time in order to learn about self-hosting and, while I have learnt about a bunch of cool web services to host, I'm still lost on where/how to start. Does anyone have, like, a very beginner guide that is not just "install this distro and click these buttons"? I have an old laptop that runs Arch (btw), but I'm not familiar with networking at all. So anything starting from "you can check your IP address using ip a" would be appreciated.

More specifically, I have a domain that I want to point to an old laptop of mine (I intend to switch to a VPS if/when I feel like the laptop is starting to lose it). How do I expose my laptop to the internet for this to work (ideally without touching my router, because I'll be traveling quite a bit with my laptop and don't mind the occasional downtime). I assume that once I'm able to type my domain name on my mobile and see it open anything from my laptop, I can then setup all the services I want via nginx, but that's step 2. I tried to follow a few online guides but, like I mentioned, they're either too simplistic (no I don't want to move to Ubuntu Server just for this) or too complex (no I don't know how DHCP works).

Thanks in advance

I only saw the app once while scrolling around on f-droid; tried it but it seemed too empty to be useful. The only place I've since seen it even being mentioned is this post, but that's also not specifically about the app. I'm genuinely curious about what exactly the point is of GNU/Jami. Is it just a p2p version of calling and messaging?
