Nice idea.

The fact that some of the people have no eyes and a weird sort of eye thing for a nose is confusing.

Also there are too many people in the elevator for the necessary awkward silence between comments.

I can't find the blog post, but I read one once that said, basically: you don't need labels or folders. You need your inbox, the archive, and trash. Once you've tended to an email, either archive it (and just use your search function later), or delete it.

I've tried unsuccessfully to maintain folder/label systems over the years, and I always end up having to search my emails anyway. So why bother with trying to make a consistent folder/label structure? I'm much more likely to remember some key words from an invoice than remember which labels I would've applied.
Ask HN: Which functional programming language should I learn?
I have experience with most of the top languages in the TIOBE Index (OO and imperative, including the functional aspects a lot of these languages provide). I also have experience with native, JVM, CLR and several JS engines, so I'm not partial to a specific runtime.

I don't have a particular side project in mind, but I would like to strengthen my understanding of functional programming concepts through practice. Which language would be a good starting point for this? Thanks in advance :)
Haha don't worry :)

Entropy fuels all chemical reactions. Atoms wouldn't be able to recombine into molecules without the entropy. The Wiki article tries to build some higher abstractions but it is simple as that.

No entropy (absolute zero temperature) leads to the absence of Brownian motion which consequently leads to inability of atoms to recombine and form new matter. All chemical reactions would totally stop at 0 degrees.

Life would not be possible without chemical reactions. Entropy is invisible fuel that powers everything and makes things tick.

OK, let me try again.

I'm the accrediting institution. For my degree in physics, you have to pass this online class on electrodynamics from MIT, because it's the best one there is. And you have to pass this other online class from Caltech on special relativity, because it's the best there is on that. And so on.

The "accrediting institution" doesn't need to own any of the course content. It can take the best of the online courses that are available. And the online stuff that's available tends to be the best of the available lecturers.

That's why it could be less expensive. You don't have to have classrooms. You don't have to pay the lecturers' salaries (though you do have to pay license fees on the video). You have to have a very small amount of administration, and you have to write and administer tests that show whether the student actually knows the material.

Western Governors University already runs on something like this model, except that I believe that they use their own content instead of the best available online content, and they only have a limited set of majors.

And, I didn't say "standardized tests". The tests would probably belong to the accrediting institution. But there need to be tests, so that they can tell that you actually learned something, instead of just sitting through the videos watching something else on your phone.
Huge change of tone from 2 months ago, ok m guessing it's because because they fear that the lab accident theory will gain more traction academically or they fear people will reveal the scale of the damage to the public vs the clearly fabricated stats we have now.

The point is that the droplets persist in the air for a little bit, and the faster you're moving, the greater the likelihood that you're moving through a space that still has suspended droplets in the air. It's like how the faster you drive, the longer your stopping distance. Your safety distance increases the faster you're moving. Six feet is for when you (and everyone else) are stationary.

Still incorrect. And I would urge you to read one of these books you reference - they ALL aim to achieve that agent's action ON ITS OWN - i.e., by learning from its environment, and NOT by being explicitly programmed.

Yes, there are many explicit if-else style programs in Russel & Norvig, & other books - but those are the 'training wheels', until better methods are developed. For actual AI, the training wheels are supposed to come off, and the agent learns and acts on its own.

Anything can be recovered with enough effort, technical knowhow and the right equipment. The distinction is what can be realistically repaired. Generally the term “unbricking” only exists because people overuse the term “bricked” (eg a phone stuck in a boot cycle isn’t a “brick”, it’s just “stuck in a boot cycle”. However if you do manage to fix a device by specialist hardware repairs then yes, I think it’s fair to say you’ve “unbricked” it.

It's more than expressing a thought with more words than necessary: so many articles start with something along the likes of

"it was a sunny May afternoon in the office of Dr. Whoever, where the cobblestones in the entrance glinted the fading sunlight. When Dr. Whoever was a boy, his father would take him out fishing..." ... and rambles on with meaningless details, containing perhaps a handful of passages in the article that are actually relevant to what the title promised me.

Perhaps a clearer example is when you find a recipe online. You will find pages of how the recipe has been in the family for ages, and how the author's family is delighted with it, and the innumerous and unproven health benefits it has, and how it's so easy to make, etc. The actual recipe is half a page.

I don't make a living doing data visualisation but I know a few people who do (Nadieh being one of them).

I don't know their rates or how exactly they've been working with clients recently.

However, there's sizeable demand (and not nearly enough supply) for that kind of high-quality dataviz work. There's also nothing that'd inherently require this work to be done non-remotely. Quite to the contrary, this kind of work particularly lends itself to being done remotely.

Knowing the tech (mostly D3.js and Processing) is only one, small component of a successful career in that field, though.

Having seen quite a few of Nadieh's (and similar data visualisation designers') talks I'd say that design, UX, an understanding of art and a creative imagination are just as important, probably even much more so.

Hi HN

As the Covid-19 pandemic was progressing, it was hard to get my head around the numbers being bandied about—and I work with data daily (LOL!)

Then on March 26, the NYT open-sourced their daily data on case counts in the US and made it available on GitHub. Using the data and a few hours a night, I built an interactive map for the web.

That effort is open source and built with Bootstrap, TypeScript, React, Redux, and Redux Sagas. You can find that here:

https://covid-19-map.leshill.app

The effect was pretty stunning. Just watching the NYC count go up day by day was pretty scary .

After getting similar feedback from others, I added some text for context and made a 1 minute video using iMovie and KeyNote (for the text slides) and posted to YouTube here:

Hope this is at least informative,

All the best and stay healthy,

I'll go ahead and say what I said in that thread again re this article : "Person doing PhD in AI here (Ive seen all of OpenAI's research, been to their office couple times, know some people there) - tbh the piece was a pretty good summary of a lot of quite common somewhat negative takes on OpenAI within research community (such as that they largely do research based on scaling up known ideas, have at times hyped up their work beyond merit, changed their tune to be for profit which is weird given they want to work in the public interest, and that despite calling themselves OpenAI they publish and open source code much less frequently than most labs -- and with profit incentive they will likely publish and open source even less). The original article also presented the positive side (OpenAI is a pretty daring endeavor to try to get AGI by scaling up known techniques as they are, and people there do seem to have their heart in the right place) ."

You can argue this without having to misrepresent or lie about what their proposal says. It hurts your credibility if you do even if you were to have a perfectly valid argument.
As someone who was very skeptical of GDPR (particularly the affect it can have on startups and whether an early business is viable with minimal staff), I think this article makes a great point. My opinion on GDPR has improved a lot after seeing the effects myself. I still don't think it's perfect by any stretch, and I'd love to see improvements, but it does seem important and I'm glad we started somewhere.

I'm not overly optimistic about this, but I do hope we can look at this and GDPR as something with pros and cons, rather than entirely perfect or entirely evil. The real world is rarely black and white, and I think this article demonstrates that nicely.

There's decent evidence that it can be passed through excretion, too. Active viral loads have been found in restrooms far in excess of what could be explained otherwise. The theory is that there's live viral particles in feces, and they get aersolized with the force of flushing. This is also consistent with the finding that diarrhea is a common symptom of coronavirus (I had it) -- there seems to be some kind of GI tract involvement that you don't see with e.g. the flu.

Great question. For starts though, you've just given me a list worth hundreds of trillions of instructions of tests.

If you can actually test on an FPGA (which is usually not possible, and if it is, it's not representative of the actual silicon/analog system you're building anyways), you can get 1T instructions in roughly ~6 hours at 50 MHz. But most hardware emulations are ~1 MHz, so now you're looking at weeks to hit 1T instructions (SPECint alone is 20T).

And what happens when you hit a bug, 2 weeks in? It may not be because you actually wrote new, buggy code, but because a new, higher performance branch predictor uncovered existing bugs. But you'll never know, because the FPGA historically gives you terrible visibility.

But in simulation (where testing is actually done), you're looking at ~1 Hz for a cpu core. Ouch. Obviously a better approach is required (unit-tests against models, formal, etc.), since at the level of detail you can't test much of anything.
> The argument for stationary bandit gangs is not that they're wonderful executives, but that they have less toxic incentives than the roving bandit gangs they displace.

One thing I like to think about is the concept of "home rule". Egypt makes an interesting case study:

By the time we can see the history of Egypt, the ruling class is seen by everyone, including themselves, as natives. (In fact, they are intrusive, but as with the ruling class of India, intrusions get forgotten over time.)

Eventually, a government collapse results in Libyan soldiers taking over the rule of Egypt. This is a disaster for cultural continuity -- this is when most of the pharaohs' tombs get robbed, by the new foreign pharaohs. It also results in formal inscriptions being written in vernacular Egyptian rather than Old Egyptian. After a relatively short run, home rule is reestablished, and formal Old Egyptian returns.[1]

More eventually, Egypt is conquered by Persia. This isn't great; the Persian emperor administers things from far away.

Egypt doesn't manage to throw off the Persians, but Alexander the Great does. Egypt is briefly part of Macedon. But Alexander dies soon afterwards, and his general Ptolemy gets Egypt out of the ensuing civil war.

Egypt is ruled by the Ptolemies for the next few hundred years. They aren't Egyptian and don't see themselves as Egyptian. They don't like the Egyptian masses and the masses don't like them. But! The Ptolemies have no power base outside Egypt. Unlike the Persian emperor, they live there, on location, and a problem for Egypt is directly a problem for them.

Eventually, Egypt is lost to Rome, and it suffers once again under the backwater treatment it got from Persia.

I don't have great information on exactly what the state of affairs was for the common man in these periods. But I strongly suspect that, as your analysis predicts, things were better under the Ptolemies, even though they were self-conceived foreigners who didn't really care for the Egyptians proper, than they were under the Persians and Romans. For Rome, as long as the grain was flowing, malaise and poverty in Egypt could be more of a plus than a minus, keeping Egypt subservient. For the Ptolemies, malaise and poverty meant defeat in war. They were in the process of going native -- Cleopatra was the first Ptolemy to be able to speak Egyptian -- when they lost it all to Rome.

[1] There was, separately, a homegrown Pharaoh who also made inscriptions in vernacular Egyptian as one part of his massive reform efforts. This got rolled back too.

Folders aren't for filing emails after you've read them. Used well, they're for filing incoming messages automatically. I have a heavily email-driven workflow, and I am active on dozens of mailing lists. My email servers filter incoming messages and deliver them directly into folders based on which list they're coming into. Another filter has a list of commerce-associated domains that get filed into folders based on which accounts they're associated with. As a result, the only mail that hits my inbox proper is mail from friends and family (plus the occasional not-filtered-yet work/list mail). Everything else lands in folders, and I prioritize opening those folders and dealing with those messages.

As you mentioned, once a message is 'consumed,' it just gets archived. But the folder system (combined with sieve filters) is what makes dealing with a ton of incoming email extremely pleasant.
