I also wrote a preemptive threaded operating system for AVR atmega 128.

At the start we had threads, pipes between threads, serial io, interrupts.

After we finished the project, I ported the system to standard UNIX system calls. Now I can tinker on it, and get full access to GDB/prints/profilers. I use signals, timers and pipes to simulate interrupts, clock and serial ports respectively.

Because I’m targeting UNIX it’s pretty easy to get started and build little toy experiments. I haven’t gotten it to compile on AVR for 10 years. But I have been maintaining it as a playground for new ideas.

Some recent additions are resumable functions (like python generators), A lisp user space, and a performance regression test suite.

A cardiotoxicity paper from the WHO in 2017 said the following:

"Despite hundreds of millions of doses administered in the treatment of malaria, there have been no reports of sudden unexplained death associated with quinine, chloroquine or amodiaquine, although each drug causes QT/QTcinterval prolongation. Unfortunately, there are relatively few prospective studies of the electrocardiographic effects of these drugs."

Chris Martenson is doing an awesome job staying on top of the science in an apolitical manner.
Yeah but it was more like “Kanye West paying someone to paint his crib” than “‘middle-class couple hiring a local guy to do up their flat”. Rich people were few and far between.
No idea why this would be downvoted, this is absolutely true - there is not just one version of what a successful life looks like. Deciding how you define success is a principle part of forming yourself as a person.

It's not okay to keep solutions for only their citizens, but it would still be in your best interest to share what you know with their citizens so that you have a lower priority of getting infected by their citizens who may travel to your place.

Humans are humans. The virus doesn't care for the politics, it will spread without regard to human-invented political borders, so the preventative measures shouldn't stop at political borders, either. That would be contradictory to the apolitical nature of the virus.

(In any case, if you shared something with them and it is actually useful, there's a good chance you're pretty close to the solution yourself, anyway.)
Saying that scale is irrelevant makes me think you are intentionally obtuse about this. FB picks which newspaper's article to show you just like newspapers choose which journalist's article to show you. And just like newspapers give a tremendous amount of power to one individual (the journalist) compared to another (you), FB can do the same for individual articles and outlets. Except FB has the kind of reach no newspaper ever had or will. They give a podium for others to climb on, they decide who gets the front seats, and they monetize it.

For all intents and purposes they should be responsible for everything that happens on the platform regardless of where the content was picked up from. They should have a responsibility but this comes in conflict with their goal to to drive engagement and profits.

Their algorithm curates what people see, shows specific links, and influences opinions. And when you can influence opinions on such a large scale and monetize it we have a conflict of interest and even a weapon. FB and others have proven this in the past. Why do you think the media is regulated so tightly around election time? FB can take even a blog post and push it so aggressively right before elections that they manage to sway opinions but still claim they were just a platform.
I mean, the data is the least I'm concerned about. It is the app itself and the way it works that it tightly integrated to my workflow.

In the case it shuts down, there's now way I'll spend my time redoing my workflow or grep stuffs over all now already scattered digital documents.
Guerrilla Public Service Redux (2017)
Yeah I am 42 and I thought that was an awesome rant except for the part about hoodies and t-shirts.

I have always preferred hoodies over hats and scarves because they are easier and more effective.

And to me t-shirts are also easier and more comfortable than dress shirts. I am from California so maybe that has something to do with it.
Let’s address the reality of the situation first. I am not interested in playing this stupid game where the private acts of private corporations suddenly become the acts of government.

A private content publisher is allowed to moderate the stuff they publish. Simon and Schuster rejecting my novel is not censorship. This principle includes highly permissive content publishers like Facebook and Twitter. I don’t think anyone here is seriously arguing that the Klan deserves a Facebook group. Obviously it’s well within Facebook’s rights as both an online business and a publicly-accessible service to kick the Klan out. So I am really not seeing what is so authoritarian about removing misinformation about public health - the only way your argument is even remotely defensible is if you wrap it up in a ridiculous thought experiment. And being banned from Facebook for posting conspiracy theories is no more Stalinist than being banned from Chuck-E-Cheese for booing Munich’s Make Believe Band.

To get to your actual point:

Shouting “fire!” in a crowded theater when there is no fire will land you in jail. Lying about the efficacy of your pharmaceutical company’s medications will (or should) land you in jail. And a successful libel/slander lawsuit can ruin you. Some of these legal issues are thorny and I have mixed feelings on them (until recently Canada has highly repressive libel laws). But certainly lying pharma executives who get people killed should go to jail. Certainly the guy who pranked the crowded theater should be held criminally liable for the resulting stampede. Free speech is not and had never been the same thing as freedom from consequences of speech.

If it’s just some guy ranting on the street then yes, congratulations, the state should leave him alone.
>For example, making a button that visually looks like a link but keeps the correct semantics takes over 20 lines of non-trivial CSS, even today.

Can you explain the use-case here? What about "being a button" do you need for the desired functionality? You just want it not to look like a button, while still acting like a button and looking like a link?
Very interesting I'm going to try it out.

What's the app written in? It has a VSCode feel to it (which is great!)... Any chance it's built in typescript like VSCode too? I'd love to write a JavaScript extension or two to customise it in the future if that's the case. Can you share what it's built with and what the future extensions will need to be built with? Thanks!
The best way for me to take notes was to have a leather note taking portfolio with a steno pad inside it. I would take fast notes on the right, and index on the left. Here I would rip out pages if I had to and throw them away.

Then in the pocket would be a college ruled journal. I would take that out and summarize everything each day. This one I kept on my bookshelf.

If I had to do it today, I would use a guillotine cutter to a page feed to a scanner to an OCR system.

Depending on what you're doing, one-time collection may be enough.

Also, many captive portals are provided to businesses by companies whose own business interest is in tracking people, and they'll absolutely correlate the data.

Rather than having to worry about whether the service you're getting internet access from will track you, make it impossible for them to do so.
After a video has been reviewed by a moderator on appeal, why isn't a block on new reports put on it? If, say, they can tell that a video hasn't been altered since the last time it was looked at, why aren't things disabled after initial flagging and review?

"Malicious actors reports, and Youtube bots autoremoved, my video four times" should not be possible.
I'm also a skeptic. Although nothing is forever, we want to get closer to forever than all the other note-taking apps.

We'll likely make a formal guarantee to open source in the case of us shutting down. Didn't realize that was a possibility until today.
The comment is more about splitting it at the undergraduate level. I think most of the medical specialties you listed will have basically the same undergraduate experience, though I could be mistaken.

> We take beautiful art for granted today

Many but not all of us do. Every time I think about all the beauty that was created in the Classical Antiquity or the Renaissance (or any other less Eurocentric moment of widespread creative spark), and how it contrasts with nearly everyone today who is seemingly hellbent on making "critical" pieces for the sake of being critical.

I understand that we need to raise awareness of certain issues, that art is also politics, that a lot "has already been done", that art expresses intent and not only depicts reality (or idealized imagery). I understand all of that, but it seems we've somehow lost track of how art can also be made just... for the sake of beauty

There's a reason hordes of tourists flock to Florence all year long, you know? Let's build more of that unquestionable beauty that transcends generations.
IMO, when I really think about the phrase "days are long, years are short", it seems like what it's saying, or maybe it's a more depressing way to interpret it, is that "you're not doing anything special/memorable in your days" -- hence the days feel long, but after they've passed, it feels short because there wasn't anything in particular that was memorable to the parents. However, do keep in mind that a lot of everyday experience like walks in the parks that are nothing special to the parents, are very special for the kids.

We have a two year old as well, and it certainly feels tough -- it's not like you can travel the world with a toddler (at least, it's out of our abilities range, haha. Some people can do it, I'm sure.), so it's all about living the everyday life (for now, until they're older) and making the most of it. SIP doesn't make it any easier too. Try to at least make the weekends interesting! Park walks are always possible, and a lot of outdoorsy nature type places are possible to go to also, just don't go to the super crowded places.

Elon has fascination for sci-fi aesthetics so no matter what, he is going to shoe horn it in.

Sci-fi UI/UX was developed in a short time under pressure when movies were being made. The authors did not consider literally anything about the implications such as ergonomics, cost, reliability, discoverability, etc. Literally zero research behind it. It was not an engineering project by any stretch of the meaning.

Sci-fi aesthetic is the cancer of our society propelled by big budget films and cultural impact worldwide. It has absolutely no place in space exploration.

All this is decoration and marketing. Personally, I also hate the new space suit design, it looks like a movie set than those badass suits astronauts used to wear. They screamed of technical prowess, not aesthetics. Emerging aesthetics were absolutely badass: https://upload.wikimedia.org/wikipedia/commons/e/e0/Tim_Kopr...

> You don't need to think about graphs or runtimes every day- but that one time each year or so that you do need to know it, it's critical that you do.

I downvoted you because it's unreasonable to expect people to memorize something they use once a year. Learn it, understand it, then look it up again when you need it.

Interviews should reflect the experience and knowledge you expect a candidate to use on a regular basis. Asking comp sci questions they don't need to know to do their job biases your hiring process to new grads rather than experienced industry veterans.

Of course it is worth to explore space. It does not "deserve" to be explored, it just pays off. There is huge amount of knowledge and resources to be had.

Of course robotic missions are better for exploration than manned mission. Manned missions costs so much we could do so many more robotic missions for the same cost. People are absolutely not required in space.

We send people into space because we can and we want. Because we keep separate track of record of things achieved by actual human beings. That's why we list who beat 100m or marathon record even though we have machines to move as around much faster. Because standing a human on a mountain, sea bed, or a piece of rock in space is an important step for us to prove we can command nature around us.

I really appreciate your approach to this argument. You really cut through any strawman fallacies by pointing out that there's a debate along a spectrum about what protecting free speech entails, but that the President needs to have limitations in his power over private companies. I think this final point is not debatable in a legal context; he does not legally have that power.
Genuine question: How is GPU accelerated rendering more prone to crashes than just doing it on the CPU?

Also, on macOS, Apple practically controls the whole stack too. Putting macOS on something that isn’t their hardware is a challenge.

Side note: there’s errata on the Intel CPUs, but I’m sure there’s also some (confidential) errata on the “A” series processors in iDevices. If iOS can work around the errata, why couldn’t macOS?
Jeez, 50$/user/year for commercial use?! That's almost as expensive as G Suite.

In the USA, anything seen from a public space, including the air, the street/sidewalk, even aimed at your yard, is legal. In most cases you can even film on someones private property if there is easement. There are exceptions, but rarely. Privacy was assumed, but never protected here.
And yet I still like the way it looks. That should tell you something.
Feature parity with Amazon Firebase?

Let me assess this, with the tip of my napkin:

1. linkedin 'firebase' + amazon (current employer) -> 695 people.

2. 10% of above = 70 FTE

3. They started (googled): They founded Firebase as a separate company in September 2011 and it launched to the public in April 2012.

1+2+3 = It's impossible you will have feature parity in next 10 years.

BUT it's possible you can achieve pareto parity, leaving off the table most complicated 20%. Good luck :)
It's certainly true that a surprising number of books are poorly written. But even if you want to win me over on the strength of your ideas rather than the prose, you still need to lead with those ideas. If a book doesn't grab me in the first 4 chapters, I'm unlikely to read much further.
This is an excellent read: https://slatestarcodex.com/2014/12/12/beware-the-man-of-one-... -- basically says one has to be very skeptical of trusting a study that suits the narrative, and how studies can be cherry-picked to align with your narrative.

The US kind of has to preserve at least a minimal manned spaceflight capability in case we really need it for something in the future. If we completely lose the infrastructure, supply chains, and institutional knowledge it will become impossible to restart from scratch in a reasonable time frame. Think about it like paying for an insurance policy. It's worth doing even if it eats into the budget for unmanned satellites and probes.
For those who aren't giant space nerds (like me) the very best place to get info on SpaceX and SpaceX launches has always been Reddit's /r/SpaceX[0]. The launch today (like all launches) has a dedicated thread[1] with mods keeping all details up to date, all links that matter organized.

It's 100% not sponsored or run by SpaceX, but honestly it's probably doing a better job than a corporate PR side could manage. Fantastic amount of details on everything in their wiki and posts, and friendly people who answer questions happily.

The difficulty there is you're talking about giving it to a lot of people in an outpatient setting.

This is the worst case in terms of risk trade-offs:

Without being admitted as a patient, you will not be monitored as closely especially for coronary complications.

Since you'll be giving it to people before the onset of severe symptoms, you'll be risking side-effects giving it to people who might have been fine without it (and most people will survive with out it).

You'll be giving it to a lot of people which again just increases the chances of serious side-effects.

(PS I hope you're doing well now).
Wx is native, but you really need to pay attention to what are the defaults on your platform. Wx either doesn't have those, or they don't align that well with other apps in the system, which is where the "off" feeling may come from. If you spend time designing it to look nice, it will look nice - but it doesn't exactly go out of its way to help you. Then ensure the same for each platform you target. (My experience, YMMV)
That's the thing. After this if I'm required to go back to an office I'm forever going to realise I'm only there to entertain these weird people who think work is about being close to people you sort of know but don't really like.
I am not an expert (but neither are you, I am guessing).

>Anybody making the case for variolation without validation would be better off making the case for vaccination with one or several of the 30 vaccine candidates under study for SARS-Cov-2 right now

The advantage variolation has over the 30 vaccine candidates, I am guessing if the question is what to do before the results of testing are available is that most of those 30 candidates will turn out after being tested to fail to confer significant immunity.

I believe that the fate of most vaccine candidates for any disease is that testing reveals that the candidate fails to confer immunity to most or all of the people it is given to. Also I believe that it usually takes at least a year to produce enough of a vaccine to test, then test, then analyze the results of the testing.

Have you seen any OS that is browser-first?
