Ditto, on a fresh Arch Linux install I was using once.

There are plenty that have 4K screens and no discrete graphics cards, the X1 Carbon from Lenovo is one, I'm pretty certain Dell, LG, etc have similar models as well.

Yes, it still falls to the same fate. It just has less intervention so it goes to that fate slower which means you can recover more energy from the system. Is the basic idea.

As an undergraduate in physics I was spared from any absurdity like that, but I knew professors got emails and the like for those types of things. However, the most amusing thing that I heard about was that our department (Physics and Astronomy) would get calls inquiring about their horoscope. Which caused us every year to change our name to Department of Psychics and Astrology on Halloween.

I would assume Hong Kong records as Cantonese is the official language (for at least English<->Cantonese), I would also assume the Guangdong province would also be a source of material as well.

I honestly only did it because I was cheap and I wanted to remake a sandwich I had consumed before. I started with a simple foccacia recipe and went from there. But I started baking with my mother years earlier so I had some experience.

I now for better or worse have the Toll House cookie recipe memorized, but I'm terrible at making baked goods look appealing.

As the only left handed member in my family, I'm now curious if I ever did that to my family. Though for tasks of that nature I may actually use either hand, or maybe I just started using the right hand because I was the weirdo (asking my mother she said she never noticed but assumed I probably just adapted and used my right hand).

As a bachelor I virtually make all my own bread so I don't really notice, but I think I do take time to figure out which way to twist before opening so maybe that is a thing.

This is just to say, the things you never think about, and I enjoyed the irony of your situation from the reverse side.

For [0], libinput from what I've seen is supposed to take the place of linux-wacom. However I have only been playing with wacom fairly recently (I got one as a Christmas present) and haven't explored linux-wacom to see what is missing. I know with respect to libinput I have had difficulties getting the extra buttons on my tablet to work and some things have been a bit rough, but I don't know if that is due to me not understanding something or what.

TL;DR Theoretically libinput is a linux-wacom replacement.

Just as a note, GPU supported code just now seems to be coming on line with like Quantum Espresso GPU version getting an alpha in 2019. I think a large part of that is due to the 64 bit precision making the speed up not as great on GPUs (and to a large extent eliminating the usage of consumer level cards which are popular at the classical molecular dynamics software like GROMACS). Plus Guassian, while having support since Kepler days note that earlier cards didn't have the memory requirements (which also is a huge problem for consumer cards) making adoption slower, because of the added costs.

Full disclosure, I don't work on processors but am in a tangentially related field.

However, I don't feel that you need to have an analytical solution to the Schrödinger equation. In fact even in chemistry we don't do analytical solutions instead using fancy basis sets which allow us to do approximations.

Regardless, I don't think even that is particularly necessary, as quantum at that level means you basically have some level of leakage where the electrons can just tunnel through the barrier created by the transistor when off. So if I had to guess most of it is just ways to rectify this leakage so it doesn't effect calculations, probably similar to a form of error correcting.

(This ignores that you may have to do some initial quantum calculations using Density Functional Theorem to get a guess at how much leakage based off the materials you are using, though if I had to guess most of that work was done a while ago.)

Except for in Parler it isn't a soundproof room? It's literally a social media site where the admins (owner of the restaurant) can see what is going on. So it is the audible example I mentioned above.

The sound proof room would be more apt for the later comparison to signal.

Admittedly, I don't know about Telegram. But I would probably guess the distinction is still there because if I had to guess Telegram doesn't advertise those groups, you have to look for them, which decreases the condition of "audibly hearing the discussion." Where as Parler being a social media platform first wants to encourage the network effect and engagement among it's users, thus encouraging this open discussion and connection among potentially dangerous elements.

Again in my non legal estimation of the law (not that I think anything I'm currently suggesting has been tried in court).

I had this exact conversation with some friends yesterday, and here was my response to them edited for clarity:

And the difference between Parler and Signal is that Parler is a social media platform, Signal is a messaging platform. It's the difference of having a group of terrorists[0] in your restaurant everyday audibly planning a terrorist attack versus being the site of a message drop that occurs discreetly. Accessory charges are likely in the former unlikely in the latter.[1]

[0]Replace terrorists with criminals or whatever is palatable to you, it was the example we were using at the time.

[1]Standard disclosure I am not a lawyer/prosecutor/etc.

I'm always glad to see this stuff move forward. I recently got back into photography and was delighted to see the state of OSS software. However, because I could never find a comparison between rawtherapee and darktable I downloaded both to try each, and I just never could understand how darktable really worked[1]. Rawtherapee just seemed instantly more intuitive. For those that have used both, is there anything I'm missing between the two? And does darktable just better mirror lightroom and therefore is better for Adobe converts?

I hope I don't start any flamewars, this is a genuine question. And I remember initially there was some statement that rawtherapee handled x-trans RAW files better but some other people said that because they use the same software it doesn't matter. I intended to write up a blog post on both of these at some point for people in the future who have these questions, but time is what it is I haven't had the time to sink into it to get an intimate understanding of both (I still have a lot of photos I need to go back and process generally).

[1]Admittedly have not put in the work of going through guides or anything it was just kind of fumbling around in the software.

edit: Didn't know asterisks italicized, though I should have... Replaces asterisk with [1] instead...

Thanks! A dataset was one of the things I was dreading searching for/building. (Maybe this was super easily searchable and I'm just a goon, again I'm early stages of passing interest).

I've recently become interested in OCR due to using Kaku on Android for trying to get better at reading Japanese. So thanks Hacker News for showing me a new version. I'd love any comments about other resources that may be good for learning. Especially because for funsies I'd like to try and develop my own.

I inherently believe that this is a U.S.-centric thing as a few commenters mentioned. Specifically a degree in the U.S. is held as a way to advance your career prospects first and it's value is often marketed as a trade off of get X dollars in debt but make Y dollars more in your career on average. So a lot of that attitude becomes I am taking this class to check boxes to get a piece of paper which says I'm worth more in the job market. I am a graduate student but understand the jadedness, especially because I had to retake virtually the same class multiple times because it wasn't "as rigorous" for this specific major as I changed majors a few times (and had to get one of those approved for a different major). But because a lot of people see it as a way for getting a better monetary outcome college in the U.S. is often treated more like a vocational school I feel so the extra "B.S." one has to go through feels like a particular waste of resources.

I enjoyed college but, I very quickly understood that its only purpose wasn't to enhance my education as I sat through multiple classes that were nearly identical to previous all because I had to check a box. And generally I felt classes moved to slow and would have been much happier studying on my own, but courses often forced my attendance. Though I am a bit unique in my ability on that admittedly.

I agree that was quite disappoint as it was one of the large reasons I bought my T470. And for those who are saying hey just use an external, that's great until your internal battery starts dying and replacing it becomes a nightmare (which for less tech savvy people it's much easier just to swap the external than dealing with the internal).

From what I've looked into it, and now I'm a novice is it's build more for illustrations. I think of inkscape more as a graphics designer software for making images and logos and things which you might use for a company logo. Where as Krita is more artistic in nature so like paintings and things (web comics). At least that has been my thoughts from my minimal exposure to both. Though I'm sure you can easily do all in either.

This right here, I am in the exact same boat. Much better than making them in powerpoint. And even though we have a (sort of) lab adobe CS key, all of my computers run linux and we only have like 5 keys which makes the process quite silly.

Now I just need to finish the figures for this paper so I can update to this newest version. But everyone in my lab is quite excited about it.

Thank you for being worth the whole reason I clicked on this link. I could have used this forever ago when I was trying to figure out how to do this to bypass a firewall (now I don't need to but this will be useful in the future).

I remembered attempting to play this game on my Dad's playstation as a kid and always crashing. Glad I can now blame it on the fact the game was "too" realistic and not my poor skills as a young child. (But let's be honest it was definitely the fact I was a young kid who had no clue what I was doing). This was a fun memory to walk down though so thanks for that!

Disclaimer, I am more referencing classical molecular dynamics in the atomic region. And what I am envisioning this type of thing for is not dependent on the mathematical model per se. So specifically my point is towards say GROMACS (or a similar MD simulation engine) where the force fields generally used for that are parameterized for biological/organic systems. Let's say we train our neural network on data fitting to lipids. So maybe a bunch of random data on lipids like their melting temperature, surface temperature, etc. Then we run the neural network simulator to model how these things form into larger structures (something that is for the most part impossible with current all atom approaches). And then we study that data to make an assessment on how certain structures can form etc.

Now if you are aware of the field, what I just described was (ignoring I do not remember the exact fitting data) the parameterization process of the MARTINI force field which is sufficiently good at lipids, kind of okay at proteins, and pretty bad at everything else. But within the bounds that you know the weakness of the system you can still use it to figure out experimental data. (Also as an aside MARTINI only got access to proteins and other things later on, thankfully force fields improve over time.)

I am mainly referring to the all atom molecular dynamics world, because that is where I am aware. But within that domain even the traditional simulators can only truly interpolate within experimental data. This is because the parameters within the simulator are generally only fit to a certain set of experimental data and therefore show poor performance anywhere else. Whether this is novel unseen molecules, different temperature domains, etc. While those parameters have gotten better they are laughably bad in certain areas.

But yes if you are creating a mathematical model from the ground and trying to use the model itself as a method to discover something about the system, then you are correct in that the new mathematical model may be able to tell you new things about the system. However, if you are trying to learn things from the simulations, then the type of simulator you are using matters less as long as it is accurate enough.

The problem with that assumption is that while those solvers are based on a mathematical foundation (though I'd argue that some NN based simulations are too some papers out of Weinan E's lab at Princeton having some decent math to an untrained eye), the parameters that are fed into those are often just fit to some experimental data. And are often only verified in a heuristic manner. So while a neural net based simulator may not be transferable in the same way as a more general simulation engine (though depending on how you write them even they generally have limits), it may be fine in a certain domain which you can show by just checking how well it fits to certain experimental data you already have in existence.

I understand that. However my comment was just a statement that the existence the person above me was implying was useful existence. As in we can all be excited about this new tool, or game, or whatever, but if we never get to use it, its usefulness is moot. So while the language certainly exists we can observe him working on it, and he could even create a game using it that would have some societal impact, the current usefulness of the language to anyone except him is as if it did not exist at all.

Of course you could make the argument that its mere existence and him highlighting certain aspects could have influences on other language designers... and wow am I going down a tangent spiral now...

Anyways: TL;DR reality is objective but words can have complex semantics

But existing for someone else, and existing where I can use it are two different things. I'm sure there are lots of cool tools and things that exist at big companies like Google (or more interestingly say the NSA) but for all my intents and purposes they don't because I can't interact with them.

A reverse corollary to Russell's Teapot? So what if there is a teapot orbiting Jupiter, I can't get it so it allows me no ability to serve tea. Therefore it might as well not exist!

I'm in a similar boat of TCL dislike. But that probably has a lot to do with my first introduction was through installing a program and having all types of difficulties doing so.

Being exposed to a language at first by trying to understand what it is doing in installing software is probably not a great introduction. I did get the software installed but my dislike remained

This was probably further increased by the fact that post that I had bad experiences with my supervisor that just soured everything about it. Even to this day where it would benefit me to use TCL, I try to avoid it in favor of languages like Python.
