My question is this- if one were to build a trading bot that bought and sold along with something like this- 1) would it be legal 2) I’m curious about the returns vs the market.
That was a biotech stock. They are very volatile. If he held long term he would've done much better. If you search for FDA catalyst dates, you can find dates when drugs are going to be approved or denied, etc. It's like a coin flip.
git is really meant to show a meaningful log of changes to the codebase. If one wanted to use it as a backup, there's no reason why one couldn't configure their editor to just run git commit -a -m "<current timestamp>" every time they saved, but that wouldn't result in a history that's useful in terms of being able to tell what actually changed and why.
I think what I liked about the TNG-era Star Trek was that, as often that there was an "antagonistic relationship with their superiors in Starfleet and/or the civilian leadership of the Federation", they also as often get along. The Federation was a government that worked. That was the baseline assumption. The show demonstrated it, the characters believed it. They were proud of being a part of it, and not just because of some ill-conceived patriotism.

Related to that is the baseline assumption of competence. Characters in Star Trek, especially ones from the Federation, were always assumed to be extremely competent and good at working together; everyone valued excellence. Sure, they were exceptions, but they were that - exceptions, around which a story or a joke could be built. I miss that world of excellence in other shows.
Covid-19 created a revolution in telemedicine. Will it stick?
I've never personally seen or used mem::forget. I'm sure it happens, of course, and I'm in agreement that the API should be unsafe. I'm just saying it's not clear that they "don't care".
Pretty great.
It let me write this really quickly with minimal effort. There were some quirks and some weird hacks I had to make when it came to working with JS, but that could also be me doing it wrong.

My biggest complaint would be around some latency issues when the connection is bad, but I knew that would be an issue when I chose it. I would definitely choose it again.
As I mentioned above, it's a biotech stock. Those sorts of jumps (and dumps) happen all the time around FDA approval dates.
This sounds like a Google interview question....
Apple's press release seemed to say that much of the functionality will be pushed in the coming months via iOS updates (since the iPhone to iPhone communication isn't exposed normally except for Find my iPhone). It's unlikely that you'll need to install an app except to say you are infected.

Google could do a similar thing via a Google Play Services update (or, you know, use this as the kick-in-the-pants to get manufacturers to start updating Android to protect the public from COVID-19).
> Only 5-20% of the population gets the flu each year.

Only 20% of America is 70,000,000 people. That's staggering. The economic impact of the flu is enormous.

> I've seen most people assuming a mortality around 1%, which is not that far off from these results. In Italy, 1% may well be correct, given how the healthcare system was overwhelmed there.

It may be 1% in Italy because the population of Lombardy was overwhelmingly old, and overwhelmingly sick. The average age of death in Italy was 80.5 and the average number of underlying medical conditions was three.
I've never bought into this idea of microservices. Always wrote high performance native servers and have yet to encounter the situation when well designed monolith running on multicore monster with gobbles of RAM failed to satisfy client. Granted it will not work for Google but what does the world care. Most of the businesses (read potential clients) will never come anywhere close to those scales.

Long time ago when computers were slow I did design some distributed applications myself - reliable IP multicast server, business process servers, map reduce type solutions like bill generation etc where it did make sense. That was long time ago and now most of those at their old scale could run on a single reasonable priced server.

Thanks for that super useful article @pomber! I read it a while ago and attempted to convert it to TypeScript and do a few extensions, here's my attempt: https://github.com/manasb-uoe/didact.
I think it has a flaw: if you find out you are infected mid-day, then if you reveal your key for the day others can impersonate you for the rest of the day, and if you don't those who you had contact with in the first part of the day won't be notified.

So my suggestion for a minimal fix would be to also reveal all advertised rolling IDs for the current day in addition to the keys for the past days.

A better fix would be to generate ID in a hierarchical fashion from the daily keys with power-of-two-length time slots, so that you only need to share O(d + log(n)) values where d is the number of days and n is the number of subdivisions in a day.

Another potential fix is to use public-key cryptography and only reveal the daily public keys; however, this requires twice as large IDs and matching requires to try to decrypt/signature-check all received IDs instead of being able to generate and lookup.
Ask HN: What is the effect of Covid-19 on HN’s traffic?
overlayfs isn't necessary either :)
I would say the main question here is if consumers would be mislead into thinking "Natural Seltan" had the same advantages over meat that artificial seltan has. I don't think they would. In fact, I think they would find that label confusing, and just stay away from it.

And let me add that if meat producers find sales under the traditional label have dropped so low they need to adopt that new one, then they would have already lost the war.

Honest question...If you aren't educated on the topic, how can you tell if there is good analysis or not? (Versus just reading and believing random cranks). Is there any way to test her hypotheses against reality?
Tangential topic.

Are masks of the type worn to protect against covid-19 effective against being identified on camera? Because this seems like an amazing excuse (in terms of a silver lining on a very dark cloud) for facemasks as 'anonymity wear' to become mainstream.
That makes much more sense than they laid out.. then again there was that whole global financial crisis that happened during that time with George W. Bush in the White House, so it seems pretty implausible still? Anyway, I found a much more compelling article that doesn't end with the sentence, "The list of financial "greed" and sleaze on the left is long. What a bunch of hypocrites."

"... the idea that propaganda could be wielded in peacetime..."

That is to say, what is now known as "PR" came from the military, who had trained people how to do this kind of work, e.g., in the role of "press agent".

It may have existed before the First World War^a but its popular use by the private sector may have happened only after more men had been trained in "PR" and had performed this work for the military.

COBOL can be a real pleasure to use.

For instance, it allows programmers to quickly create user interfaces by declaratively describing them, in a so called SCREEN SECTION.

The resulting interfaces are very efficient for text entry, and allow users to quickly get a lot of work done. The interaction is so much more efficient than what we are used to with current technologies that it can barely be described or thought about in today's terms.

Regarding the underlying theme of legacy systems, here is an interesting presentation by Jonathan Blow, citing various examples of earlier civilizations losing access to technologies they once had:

https://www.youtube.com/watch?v=pW-SOdj4Kkk

I think in terms of user interfaces, we are on a downward path in several important ways, and I highly recommend checking out earlier technologies that were in many ways an improvement over what we are working with today.

Thanks, I looked at the code later and confirmed that too. The visual style is very similar to MindNode, but it's rebuilt using d3.
Maybe instead of "utopia" I should've said "as close to utopia as you can get without shattering your suspension of disbelief". The world was designed as a reachable utopia, and in my eyes, the vision didn't decay fast enough when Roddenbery left the scene to be lost by the time of ENT.

> While, as noted above, it's flawed even then, it really doesn't work for DS9, VOY, or ENT.

Compared to what? Relative to pretty much every other show, I think it worked really well. The baseline is still visibly much more idealistic than everything else (including post-ENT Star Trek).
I just saw a netflix documentary, 'operation odessa', where two guys were buying russian helos and even a sub for the Cali cartel. I am not amazed at the resourcefulness of the human animal. Anything we make (including information) gets weaponized for bad actors. And that's only the stuff we know about.

There is no other move. The reason they own that much is because USTs are deep and liquid. There is virtually no other market in the world where you can deploy $1trn (certainly no market outside the US).
I thought about adding a transparent layer so that my daughter and parents can draw on a story. I never thought about it from a therapy point of view, but that is just not an area I am familiar with - interesting though. I would be super happy if this can be used for that.

As far as open sourcing it goes - I have not made it open source ATM, but it is definitely something I am considering.
I've only ever been to 'average schools.' With no data to back up this claim, I'd be willing to bet even the worst students that graduate from top schools are still better than the lower end of average from average schools, because the barrier to entry (and continued attendance) at top schools is higher. I'd also not be surprised if your claim of top school graduates being less honest were true, for the same reasons.

If I were in a position to interview and hire someone, graduating from a top school would at least garner some attention, assuming the degree was relevant, but it's not a 'free pass' through any of the steps of the interview process, and may even earn them a more critical assessment in the implicit 'culture fit/personality' category.

This is just my opinion on the matter, not trying to make any sort of factual claims.
There are a lot of times that it isn't feasible, and they are running a large trial with a control group right now. The drug has a reasonable chance of working so people requested compassionate use, so the company figured they might as well track the compassionate use patients to get some data out of them. It's not like they're using this as a basis for getting FDA approval.
Agreed!

While the developed part of China is gigantic, my understanding is that half the country still lives in the countryside and is relatively underdeveloped, and the government is working to rapidly move them to cities.
I have the same problem, although perhaps not as severe. I feel like they’re falling off and have to adjust them. Also tried all tip sizes and they all test as good fit as well, which is odd. All my previous in-ear felt like they fit better and also seal the noise out better naturally (without any noise cancellation)

But my biggest disappointment is the mic quality with my MacBook. Apparently some limitation in Bluetooth or something? No idea but mic sounds like crap. Works great on the phone but I hardly talk on my phone ...
The German survey showed an actual fatality rate of 0.37% vs the flu at 0.1%. We know herd immunity is in the cards due to the lack of mutation of COVID, and that kicks in at 60-70% of the population.

The German study also suggested up to 15% of people may already have it, so we can further reduce this number (an incremental 45-55% of the population getting infected) -- So, if we run some simple arithmetic, we'll see the number of fatalities will be approximately 60-70K.

This is in line with the number of fatalities in a difficult flu season. The difference is because COVID does not mutate (or has not yet), this will be a one-off, one-time, one-year issue. The flu kills 60,000 each and every year. The Swedes have it right.

We can mitigate this by isolating the vulnerable.

So yes, we are, in fact, overreacting.

[EDIT] I wonder if this is in fact in excess of deaths we'd see anyways. I'd imagine an 80.5 year old with 3 underlying medical conditions (average in Italy of the dead) isn't just as vulnerable to a bad flu as they are to COVID, so if COVID takes them, the flu won't.

If it's really not that bad, I would guess that the panic is because this is the first time we've been able to observe a brand-new cold virus as it spreads around the world. When the general public starts to understand all of the damage that these things do, and how quickly they can spread, it's understandably pretty scary. Plus a whole bunch of other factors.
It's a nice signal, but yeah, theres a reason they're running a large randomized controlled trial right now for FDA approval - they arent likely to get approval just based on this.

hmm i guess ill have to do some reading. I am using sockets.io and from what I read is it does exactly what you said. First http and then sockets (but i could be wrong).
This is anyway been a sideproject of mine to learn about web sockets.
FYI your link is broken.

Agreed, the only mention of using different technology has come up in the current project is in discussions of Typescript vs plain JavaScript. That’s been the only bring-your-own-technology for the most part, since we’ve standardized on React and some shared libraries like Lodash.

We’ve primarily benefitted from the forced feature and team isolation (aka domain boundaries if you would), plus it gives teams more granular control over their deployments. So, pretty much just what you described.

Another benefit has been our ability to build once and share features across different applications, since we have a few of those for reasons. Teams can build out different “views” (roughly) for different use cases on different apps which share the core functionality.
I'm not forgetting. That's my point. The sales are remote, and thus cheaper. No plane flights, no crazy expensive wine at dinner with customer.

And sure, they'll revert back, losing the efficiency gains once the government stops accidentally intervening in sales practices.
(It's currently (among other points) debated how well the tests used for the Gangelt survey can tell SARS-CoV-2 from other coronaviruses, and given how little they've published unclear how they corrected for that. Hopefully they'll release more info soon, but lots of experts are skeptical of this specific study, they might very well have classified a bunch of folks that had a cold as "corona")

Why not simply allow the general population to breathe Covid19 virus particles that have been exposed themselves to UVC light in a 2 meter long tube at slow air flow ? I assume that would sterilize the incoming air, while allowing immunity to build.
Another way to put it: this page not only needs some editorial cleanup, it deserves it.

I had no idea of the politics behind the old-school TV standards -- I'd always assumed that they emerged fully formed from an archaeo-MPEG organization of some sort, where a bunch of industry players cooperated and pooled their patents, and where the regulators got involved only at the rubber-stamp stage.

It was well worth the time needed to plow through the verbiage, but not everybody will give it the same chance I did, which is a bummer.
Ask HN: P2P Bluetooth Bartering Network Ideas?
Something I've been thinking a lot about lately is what we would do in a lockdown situation if the internet went out. We've grown very dependent on the internet for communicating our needs to each other, and if it went out, I worry people would not be able to get their needs met without resorting to the old analog ways that we haven't relied on for a long time.

When the Hong Kong protests started, protesters were using Bridgefy[0] to create an ad-hoc bluetooth mesh network to route messages to one another. I think it might be interesting to apply this idea for bartering.

The idea would be something like: you list items/services that you have/provide and items/services that you want/need. As you navigate out in the world, your phone can connect to people around you via the P2P bluetooth routing network and share your needs as well as exploring your peers needs. Each peer would store your information, and you would store each peers information, for later propagation to other peers.

The end goal would be to be matched up directly with a peer who has something you need, with you having something they need. Or, being matched indirectly with a chain of peers for which the resulting exchanges would lead to the desired outcome.

Is there any merit in this idea?

0. https://www.bridgefy.me/
Yeah, but perhaps he knew in advance that the FDA would approve?

Of course, it could also have been modelling based on public info or simple gambling.
They could have selected withing ventilated patients for patients more likely to survive if they thought compassionate use might be most effective in patients that have a shot. They're running a large controlled trial so we should know more soon enough

my gut tells me demand must be surging for shipping broadly, do we have enough drivers?

Roads are clear right now, are delivery times decreasing?

Fuel prices must be down, that means margins are higher, are drivers being paid more?

Or are the unemployed drivers all suddenly employed due to some getting sick.

The way we use Slack at work, most conversations spin out to threads, and there is no jumbling up. If people in your organization aren't disciplined enough for Slack threads, I can't imagine that those people would be disciplined enough for keeping conversations separate either.

Well there is always at least one competitor as the military could in source the job. I am not surprised at all about the ability to do the job at lower costs.
It's an old, creaky language with a lot of misfeatures and barnacles, but it is widespread and there are a lot of jobs.

Like any chore, the best thing to do is hold your nose and just start working. Focus on short term wins. Knock out each feature and move on to the next. As you knock out features, take some time to learn the libraries and tech in more detail. After a while, you may not like it, but at least it will become tolerable and you'll have a skill people will pay you for.
Without disclosing more this is the situation.

The patents violated expire in 2021 so it is likely they are holding out.
IIRC this idea is the origin of the word “vaccine” - from vache, French for “cow” - people used to intentionally get infected with cow pox 300 years ago, and it would confer protection against smallpox. On phone so hard to check and link.

I have been working on a project and have some experience with DB2/AS400, it is not as old as COBOL. It is not very fun or exciting and stackoverflow lacks much information, a lot of trial and error.

I can't believe how widespread these old systems are. I am surprised nobody has decided to update them, I mean when these old developers die or retire......they will have a hard time migrating to a newer systems.
