It's not about removing a feature, it's about keeping it there but monopolizing access to it. If the feature goes away entirely, that's fine. And then somebody else can come back and implement it themselves.

But if the company gives themselves access to that feature and not anybody else (even with the permission of the device owner), and restricts anyone else from reimplementing it, that creates a monopoly which they would then be abusing by restricting what competing app developers can do.

Security is the owner of the device controlling what runs on it. Monopoly abuse is the manufacturer of the device doing so against the will of the owner of the device.
The paper is available on Sci-hub, but the paper itself is pretty light, referring primarily to the supplemental material[1] for details about the tests. I can't judge about the tests, but their control was "Negative human serum(IgA/IgM/IgG)" according to the supplemental materials, and if I understand correctly this is simply a basic serum that would always test negative and so I think this adds some credence to the idea that it might not be specific enough. Maybe it wasn't possible to get a control with an older coronavirus?

In any case, I agree that it's surprising, because knowing what we do about the virus now, if it was in the population back in September and assuming that the numbers in the general population were a lot higher than 23 in September, I think something would have been noticed earlier, although I guess it's somewhat plausible that it could have been masked by the normal autumn/winter flu hospitalizations. I also think it would have been caught in the research that the Italian NIH did earlier this year when they looked at wastewater[2] and found that it was there in mid-December 2019 but tested from October. Given these, plus this paper being both light on details and being published in what I can tell as a small journal makes me skeptical.

Discover the “Done for You” Japanese Tonic to Melt 3 Pounds Every 3.5 Days
In my professional environment we use python because of the cost, definitely not because we want to post it anywhere.

And this is not an opinion on how companies measure cost or how one language is better than another but maybe trying to explain, and I think underestimate, popularity of Python needs a little bit more insight.
Python is an extremely expressive language, that lets you prototype and experiment very rapidly. In many cases, with some cleanups, refactorings, and calls to C modules like numpy, you can convert those prototypes into sufficiently performant real implementations.

Here's a recent write-up of mine where almost all of the time is spent in C extensions but where it was much faster to develop and code in python: https://www.jefftk.com/p/sharding-the-brigade
Thanks I did and recovered nicely from it through therapy and medication
This is exactly why I believe a dutiful representation of the 1st amendment in the Internet includes anti-botting measures, since bots flood the town-hall with un-measured broadcasting, shuttering out any and all active speech. But beyond anti-botting and one or two other very minor holds, a public forum should have no other restrictions of moderation. There is an exact restriction needed for the moderation to itself not be speech-impacting either by too much or too little of it.
You're thinking in an us-vs-them mentality. Really, we should be working towards a community where people can respect differing opinions, and not just a bunch of isolated sites full of extremists on either side.
I think this is a misunderstanding. Social platform users have little reason to leave one platform for another. Censorship is one of those few reasons. Censorship 8s at a very simple level telling those with different thoughts to go start a tribe somewhere else.

Twitter isn't making good decisions. The killed Vine and gave Musicaly and then TikTok oxygen. Their censorship is giving rise to competitors.
I've always thought about making a shitlist.

Maybe you've just inspired me to actually do it.

What about manual tests? You know, just running the app on your machine and check if it works/how it works.

You're forced to either share the aws resources with other devs or provision separate resources for each dev which is a big PITA.
I think it just delays a bigger problem, kicks the can down the road.

In 2-4 years' time, we'll have an even bigger festering cesspool of self-reinforced beliefs than ever before, and an more difficult time having rational discourse among our society about how to run it.
I know you can scrape only audio from YouTube with YouTubeDL but it’s somewhat annoying
Web/backend programming with Ruby and Ruby on Rails. I quite enjoy writing Ruby code.

I also dabble in Elixir as a hobby but not many places are using it. It's a cool language though.
Apple: Are M1 Macs ready for developers?
Yes, absolutely. And to be honest to get started with it for a software developer which doesn't have any "cloud" experience is pretty rough. Suddenly that developer needs to have a understanding of AWS in general, IAM, CloudFormation and all the services which can be utilized to avoid having to write custom code. It's a steep and long learning curve.
I just installed KDE Plasma on Ubuntu as an experiment.

African Mango for Weight Loss

Easy to reach if you use spot lighting. I counted a bit less than 30 in a (tiny for American standards) 100sqm house.
From reading the article, the main reason seems like having (way) less competition. Especially with cheaper acquisition channels (I've been doing research [1] on this topic for 2+ years and noticed this trend), where you have less businesses advertise on Facebook/Google, bringing CPC costs down.

I wonder if the "law of shitty clickthroughts" [2] applies here as well. What if you have a huge # of founders reading the advice; acting on it and starting new businesses just because Paul Graham told them so? Then starting a startup in a bad economy would no longer be an advantage. Somewhere in May Gumroad founder tweeted that they have record numbers of people signing up, and that may be an early sign that thing sort of thing is already happening.

I think Blender and Figma are good, professional tools. For the rest of them, I'm sure they work fine if you don't need to produce extremely polished stuff at volume— but they're not even close to good for that use case. (which is what my comment was about) I could see a UX Designer who works primarily in wireframes and such things getting by fine with linux, but not someone who works primarily in visuals.
I got that same result from the book Visual Complex Analysis. In retrospect it seems stupid, but until then I actually believed, to the extent I considered it at all, that it was just a happy coincidence that e^x is its own first derivative.

The periodic table is limited. Of all metals, lithium is the lightest. It also has the highest mass-specific conductivity and the highest chemical specific energy of all the metals.

Hydrogen is not a solid or a liquid at room temperature and is also too volumetrically in-dense.
Context is very important because otherwise you can't claim that the money could've been feasibly spent better and can't even distinguish between loss from gross incompetence or just normal fluctuations.

The Norwegian Govt Pension Fund manages $1 trillion of assets. It's value is likely to fluctuate by billions each day. Would you level the same accusations against them?

Size matters tremendously for these things.
You can also argue that a recession is a better time than usual to start a company. Your opportunity cost is a little bit less (due to the job market), customers are a looking to save money are, perhaps, more willing to take on risk to reduce expenses, and finally there is more likely to be talent available at a cost you can pay due to layoffs and a slowdown in hiring among established businesses. Anecdotally there are lots of companies which got started in a recession, FedEx + the tech ones written in a sister comment.
Repositories which will ignore you need to communicate and establish these clear goals in the README:

No Pull Requests: Author(s) will collaborate within a restricted group and do not wish to "politely refuse" your t-shirt contest contributions.
I have no strong opinion on serverless but I’ve used Rails for 13 years now (in massive $multi-million SaaS products as well as hobby projects) and it still makes me happy. I keep thinking about learning Node and React but I just can’t be bothered because Rails lets me get things done so quickly while also being a joy to write Ruby and Rspec.

Regarding hosting, I think this is actually a great time to host Rails apps either via Heroku, via the new Digital Ocean k8s app cluster or – and this is my new favourite tool – using Hatchbox.io to deploy apps to Digital Ocean or AWS. It’s a dream!
Classic projection. Say one thing do another. If that is not an example of hostile company then I don't know what is. At least they don't yet harvest your DNA, make a clone of you and force him or her to work in their factories.
I got my pinephone (Manjaro) last week and tried all OSs there are for it; I really love the idea of having a real Linux device in my pocket (that's why I have the Pandora, Pyra + GPD pocket 1 as well); it is such a difference having full control and being able to change whatever how you work instead of having large corps decide. Also shows, by the 'missing apps' between ecosystems, how much we need replacements for all the proprietary social sites, chat, collaboration etc.

However there is a lot that needs to be done software wise, which made me think that if I want to have a solid Linux device that really fits in my pocket like a phone with actual speech and 4g(5g?) then a lot more people will need to help with this. I don't know how that will happen, but, like I did with the Pandora, with this device I will try to work with the community in reporting and fixing bugs.

For now, this is a device for people who like freedom of their device (well, at least as much as we can get with modern circuits) and who like to tinker. I would recommend it to those people who envision an open source phone in their future; we need to help + stimulate the people trying.

Edit: it is trivial to try all OSs, so whatever you buy, you can switch rather rapidly and take them all for a spin.
The specs say it's 78"x75" (98"x75" for large version) when open. How much space you want beyond that is up to you I presume as it depends on your door position and layout of rest of room. If you just have a couch then that's probably a couple feet around for entrance and 4 feet for the couch. So roughly you'd want a 10' x 11' room.
> I don't think turning issues off is a sign of a serious project that should be used by many people in production

> Above all, such behaviour signals to me that there is only 1 person making commits / merging PRs and they are kind of tired of OSS (which is fine, by the way).

The linux kernel doesn't have an issue page and PRs receive a polite comment on how to send their PRs as patches outside of github.

It would be kinda insane right now for a barista even to handle any customer's cup, let alone put it down on the counters and machines, where it could touch the spouts and pitchers and whatnot. And to be honest, it still makes sense even without a pandemic, even if the stakes aren't as high. E. coli will always be around.
I think you mean “OS X” or “Mac OS X”
Everyone's detectors of this delta seem to have different thresholds of sensitivity... Simply put, some frogs feel small increments of water's temperature and try to warn others, so that they work out the means of escape instead of keeping their pool party going, but for those partying the increments pass as not alarming.

That of course does not mean that less sensitive ones don't feel some uneasiness in the environment. They do, but the cook keeps dressing the heating broth with promises of better future, and lulls the frogs into attributing this uneasiness to depression. Because you see, psychiatry is just another cook's tool among forks, spoons and knives.

Erich Fromm did not use the term 'punitive psychiatry' for no reason.
NiCd is actually more capable than NiMh, but suffers from memory issues (capacity decreases significantly if not carefully discharged and recharged; ie you cannot “top them off” without sacrificing capacity.

Again, speaking from my lived experience, NiCd pushed to the limit resulted in many gnarly fires in high performance RC use, NiMh was never a contender given low output (again low discharge rates). LiPo is king here, both in terms of output and weight/power, but overcharging or excessive discharging results in thermal runaway. Lithium ion is far safer, but less effective.
No "Edition" but Plasma Mobile is supported on PureOS/Librem 5 and it's possible to switch to use that in place of Phosh should you want: https://developer.puri.sm/Librem5/Development_Environment/Bo...

I am not sure how up to date Plasma Mobile is in these repos though. It's been a while since I tried it out.
It's pretty useful as a cheat sheet or concise tutorial when learning a new language.
> Any code which you do not know how to structure within Java's type system can be written with some Objects/Maps/Collections and a bit of runtime logic

Yeah, but that means jumping through hoops because of the lack of the typesystem. And that's what many people don't like, hence the whole thread. For you that might be fine, but please understand that there are other people out that who are not okay with it so easily.

> Java's type system is sufficiently powerful for 99% of real-world use cases

Rather the opposite. Every big project that uses reflection/introspection or annotations or some kind of code generation tooling shows that the typesystem is not sufficient. Yeah, there are some cases where the above techniques were used and could have been avoided (while keeping typesafety), but often they are just required.

And then Java does not even have proper sumtypes or union types (enums only work when the structure is identical and I mean... we could count some strange workarounds with static classes and private constructors that pretty much no one uses due to horrible ergonomics). And these literally appear everywhere.

I diagnose that you are suffering from the famous http://wiki.c2.com/?BlubParadox
For me it's the LCD screen versus an AMOLED that is a big blocker on mobile devices.

But as I understand for now this will probably mostly be used by hackers and developers themselves, not as a daily driver for lambda users who are conscious about freedom and privacy yet, so the hardware choices make sense.
The package names and process names won't change, so this just hides important info.
Your browser hangs, you go into htop, you realize you're not sure what it's called. Same with installing them or uninstalling them. I do not think this is an area where you should dumb things down.
Agriculture PhD plus even modest data science skills is hugely in demand at the giant ag-biotech company where I work. Many of the data engineers I lead are former science PhDs. Literally all of our people strategy discussions in R&D are about how we need more people like you. There are only a handful of big science companies left in ag, but I bet the other ones have similar needs.
Edit: I seriously don't think many people...
Fuck no, get your company to not be dumbasses.

Ask HN: Good resources on robotics for software engineers
I would love to learn about robotics development including
- writing the software
- sourcing and assembly of parta
- (eventually) design.

Are there any good places to find kits/projects/reading material/ directed at my demographic?

For those working in robotics - what's the best path there for someone working as an intermediate back end developer and dabbling as a compiler engineer?
Feynman was asked in a seminar why the individual terms of the pertubation expansion have meaning. Basically he cannot fathom the question and his (correct) answer is only the whole sum has a meaning. From 10:00 onwards, quite interesting, https://www.youtube.com/watch?v=72us6pnbEvE&list=PLYuIDo1vZp...
Of course virtual particles are only present in the individual terms of the pertubation expansion, so their reality is as iffy.
I'm not sure that we can provably say that they LEAD to crimes. I think there's a strong case to be made that people interested in carrying out these crimes find like minded people online and engage in meme culture. You can probably make a good case that things like 8chan encourage copy-cat elements in these attacks.

I'm just not quite sure the case has been convincingly made that internet cess pools generate crime that would't otherwise happen. I could probably be convinced otherwise, but I'm not sure.
There's a lot of things to say but I'm just going to do a non exhaustive lazy comment:

Symbolic AI is a big family:

For datasets babelnet has been a big improvement but is not that much recent.

For symbolic formats the classic OWL/RDF way has been enhanced with SHACL which allow I believe to dynamically create schema that validate the semantic web graph

HyperGraphs and metagraphs are trending (check it out it's a datastructure that is actually more expressive than graphs)

Truth is: Hybrid AI is not original, it is obvious to anyone knowledgeable that you must use sota neural networks for preprocessing tasks such as POS tagging, universal dependency parsing, NER, etc

Those gathered metadata will feed the symbolic engine/DB

The truth is that almost zero hybrid AI systems exists or they have a very limited scope.
Some tasks such as coreference resolution are currently neural only but a symbolic semantic understanding would improve the state of the art, same for word sense disambiguation.

Even the task of semantic parsing is almost only using neural networks, symbolic just isn't funded nowadays or researchers are ashamed of giving a new life to this paradigm which is ridiculous.

On the other hand some researchers are trying too hard to implement logic in neural networks which is to me a by design mismatch.

The only projects worth following that I know are:
Cyc
Wolfram language
And the only "promising" one opencog.
I'm currently researching on how to implement true semantic parsing but I'm not gonna expand on my work until it is ready.
To sum it up: NLU is not ready for primetime and almost nobody is truly working on it (but a lot of people pretend to work on it by just pushing a bit further the illusion of understanding that comes from amalgaming correlation as causation)
Thanks for posting the article :)

The structure of the article was an experiment, and it’s probably too long.
Guard Clauses – How to Clean Up Conditionals
Second this. I’m working on a set of ideas about how best to enable arbitrary learning trajectories through a knowledge graph — partly in an effort to better capture my own learning in mathematical topics. I liked how Quantum Country integrated spaced repetition into its presentation of quantum computing, but I think you could go further and structure all knowledge you wish to communicate in a graph form. There are so many reasons to do this: it’s a graph in your head anyway, and if a machine can track and manage that graph it can better help you navigate it in a learning-optimal way. Just try reading some math on wikipedia and you’ll see where this could really shine. Currently it’s a frustrating experience because there are many slices of information that you might benefit from when you are looking up eg the article on distributive lattices, but the optimal slice to see depends on what examples you’ve encountered, what other topics are fresh in your mind, and what your short term goals are. Of course a textbook is a particular curated walk through this graph, but people are different, and there is no walk that is optimal for all people. A dedicated expert teacher can curate a path specifically for a learner, but almost no one can afford to employ such a teacher for them. If machines can handle the UX aspects of this graph-walking and graph-building for us (there are many simple ideas that fit into this), I believe we could have a real step change in learning efficiency with only modest investments in building such graphs. And the truth is, such graphs are actually fun to build because they are so interactive! It’s very similar to the semantic web, but catering specificity to humans and their idiosyncratic educational needs rather than to more nebulous things about machine reasoning or scripting.
I think we need regulation that any API in the OS cannot be closed and end user should be given all keys. Current situation is untenable.
At some point we'll need to deal with the fact that the clubs self-reinforce any beliefs the tribe wants to put forward, and isolate them further from society, creating true problems for actually running said society.

At some point we'll need to have a psychological nuclear weapon disarmament... the question is when and how, not if.
The iOS Covid-19 app ecosystem has become a privacy minefield
Surely that's one of the many factors. The opposite is also true.

For instance, pre-election, for some niches US FB ads bids were totally out of whack. Or the fact that it's been high ever since the COVID caused eCommerce boom, globally.
In India, that 67 USD is the difference between kids going to school with a full belly, and working menial jobs with empty stomachs.

Have some respect towards struggles of fellow human beings.
I think we’re on the same page here with thinking Python wrapping another language is an alright way to do things.

There might be room for going lower with Python via interpreters like PyPy. Memory usage will still be high but speed will improve and you get the benefit of Python’s ease of use. For some that’s what matters most.

Personally I’m looking for a language that marries Python’s ease of composition and simple package building with typing that speeds up development in an IDE. I haven’t found that language yet. I’d be interested to hear any suggestions you have if you’ve gone down that road.
