I meant python coming into vogue for signal processing/controls, sorry if that was unclear. And that's mostly anecdotal.

There's a lot of internal tooling around MATLAB that would take a lot of work to replace with Python. Like for example, I know a company that has a verilog compiler for their matlab models. That's not going to be rewritten for python.

MATLAB toolchains are also easy to maintain, since they're so damn expensive and locked down. Compared to python, which... isn't always straightforward.

And like I said before, MATLAB is just a fancy and expensive calculator. It's number crunch first, script second, and language third. Julia and python have a different balance, at least to me.

If I'm doing something quick and dirty, reaching for MATLAB is the absolute fastest way for me to do it, and the easiest to record. With python that's not true at all.

PS: I don't think I've ever seen someone use Labview to write and debug a DSP algorithm, so we've probably experienced totally different industries.
The bits about hrtf made me smile : this technology is at least 25 years old. That’s how every single 3D audio over headphone has been done since the beginning.
Add "for iPhone and iPad" to the title please.
Sorry, this is bullshit. Government needs to contract 3m and the like to make as many masks as they can, as fast as they can, ASAP.

They needed to have done this months ago. Instead of running a propaganda campaign that masks are supposedly not effective against coronavirus and that we should not buy them anyway because we need to save them for the hospital workers who really need them. Completely disingenuous.

It’s beyond frustrating to be told to conserve face masks in the face of a pandemic rather than to purchase contracts to ensure companies produce what we need.

China is currently making 200 million masks a day. In addition, China and South Korea attribute much of their success at containment of coronavirus to the use of masks.

Making masks available for all (like South Korea who is giving every citizen and resident an allotment of 2 face masks/week) + a mandate for all to wear face masks would do so much to curb this pandemic. But instead we’re running this crazy experiment of in essence shutting down our economy via mandatory business and company closures. Not thinking through the real long term damage and consequences of such actions. Unemployment. Social unrest. Destruction of business.

Some more food for thought. Jack Ma was able to secure and send 1 million face masks to the US already. If government won’t act, private citizens and foundations (I’m looking at you Bill Gates Foundation) can.
If I remember figures properly, wet market and other exotic animal husbandry industry in China employs close to 10 million. Extrapolate for rest of the world (bushmeat etc). It's not going to get banned, even the one in China I surmise is going to be temporary like SARS, albeit depends on domestic backlash. If anything there will be some actual enforced regulation / intervention to reduced risks. I.e. maybe everyone who works or interacts with the industry will be tracked using technology developed for COVID quarantine.

Also it's important to highlight, there is NO evidence the wet market was the source of COVID, they found older cases back in mid November with no relation to it. The wet market was simply the first hotspot - and seeing how contagious the virus is even in clean environments, the level of squalor wouldn't have made much of a difference. The authorities closed it down because that's where tracing led them, which led to conjecture that inertia-ed into likely cause. Now you still have idiots who thinks it's bat soup. I haven't seen a correction at all since there's more pressing local COVID news. It's like the last ebola outbreak, people were blaming Africans for eating bush meat but patient-0 was traced to a kid playing under a tree where some bats slept in.

Vitamin D Supplementation Could Prevent and Treat Influenza, Coronavirus, etc
Well, if you are resorting to VMWare/VirtualBox -- you might as well use WSL, since it's just a VM optimized for OS integration.

Wine, OTOH, is a runtime, not a VM... and I've personally never been able to get it to work (I'm sure this speaks to my lack of knowledge more than the merits of the project). I've had issues with WSL, but it's not really comparable.

Miracle (noun): an extraordinary and welcome event that is not explicable by natural or scientific laws and is therefore attributed to a divine agency.
Title taken from the last line of the abstract. Below is the abstract in full:

> Low vitamin D status in winter permits viral epidemics. During winter, people who do not take vitamin D supplements are likely to have low serum 25-hydroxyvitamin D [25(OH)D] concentrations. Vitamin D can reduce the risk of viral epidemics and pandemics in several ways. First, higher 25(OH)D concentrations reduce the risk of many chronic diseases, including cancers, cardiovascular disease, chronic respiratory tract infections (RTIs), diabetes mellitus, and hypertension. Patients with chronic diseases have significantly higher risk of death from RTIs than otherwise healthy people. Second, vitamin D reduces risk of RTIs through three mechanisms: maintaining tight junctions, killing enveloped viruses through induction of cathelicidin and defensins, and reducing production of proinflammatory cytokines by the innate immune system, thereby reducing the risk of a cytokine storm leading to pneumonia. Observational and supplementation trials have reported higher 25(OH)D concentrations associated with reduced risk of dengue, hepatitis, herpesvirus, hepatitis B and C viruses, human immunodeficiency virus, influenza, respiratory syncytial virus infections, and pneumonia. Results of a community field trial reported herein indicated that 25(OH)D concentrations above 50 ng/ml (125 nmol/l) vs. <20 ng/ml were associated with a 27% reduction in influenza-like illnesses. From the available evidence, we hypothesize that raising serum 25(OH)D concentrations through vitamin D supplementation could reduce the incidence, severity, and risk of death from influenza, pneumonia, and the current COVID-19 epidemic.

Another off-topic question (using this forum as your author page is quite discouraging about sending you emails ....)

What's the reason for naming cyclog files with the time they were closed? (other than that's how djb did it?), since this information is available easily with 'ls -l'?

I use a logger that opens a $CREATE_TIMESTAMP.u file, and makes "current" a symbolic link to it; and on close renames it to ".s", which I find more intuitive and informative (also provides time between log creation and first message, which is unavailable with cyclog). I was considering changing the ".u"/".s" marking to be an attribute (-w or +i or +t to signify "safely closed") to help repeated rsyncs of log directories, but haven't done that yet.

I'm sure there's some useful aspect of existing cyclog/multilog behaviour that I'm missing, but I haven't been able to figure what it is for the last 10 years ...
From what I understand, it is a very cheap and easy drug to manufacture, having been designed for mass production in a previous era, as well as being a relatively simple chemical formula (some hydrocarbons, amines, a chloride?).

> Eliminating poverty with redistribution and active labor market policies would mean fewer targets.

I think you'd need to prove the direction of causality here to be convincing.

> Making policing an easier job would attract less problematic people.

What are "problematic people"? I find this judgment to be very, very troubling. Is it that "problematic people" are becoming police officers? Or that something about the job is causing problematic behaviors in people like you and I?

> Hiring a lot more cops and banning guns would greatly reduce the stress cops are under.

This seems downright preposterous to me. Guns aren't a significant cause of death for cops. Cars (including their own cars) are a far bigger threat. Moreover, there is no evidence to suggest that places where guns are materially banned enjoy less police corruption. Chicago has has some of the most draconian gun laws in the nation for decades and also has a police department indistinguishable from a criminal cartel by most measures.

> The cops in prosperous, egalitarian places are generally pretty chill, so the idea is to recreate those conditions.

Again, I suspect the causality may run in the other direction.
in 1981 the (west) german government passed a law that over the next 30 years a nationwide fiber net should be established. sadly, in 1982 when helmut kohl (a conservative) became cancelor these plans were scrapped. instead we got cable tv.
one reason was cost of course - cable was 60% cheaper than fiber.
another much darker reason was: the public tv back then was, from a conservative standpoint, very leftish (e.g. shows like "monitor" or "panorama"). the conservative leaders couldn't control public tv, but they could open the gates for a nationwide private tv sector. and they did.

I'm shocked at how modern this bird looks considering it coexisted with dinosaurs. I thought birds looked more like feathered reptiles at that point, but I guess Archaeopteryx is 125 million years ago (putting the new fossil half way between Arch' and us).
I don't think this would be how most people want to live. There are diseases all the time and the world cannot be turned into a clean room for the rest of all times.

It would be better instead to make sure that people have well working immune systems, lead kind of healthy lives and have high living standards. Also Ecosystems should be better enclosed (-> no bush/game meat), so viruses from there don't merge into civilization. It's not unlikely that that's what happened with HIV, Ebola and now Corona...

> Regarding the examples you raised: the liar paradox can be solved

There are various proposed solutions, but they all have drawbacks. You have to compare the drawbacks of the different options. (From my limited memory, your proposed solution is not one of the standard solutions proposed in the literature.)

> As for Russell's paradox, as far as I know this has been solved in ZF theory

ZF theory pays a price – the restriction of the axiom of comprehension. The point is you don't solve Russell's paradox for free, every solution has its price, every solution involves giving up some component of naïve set theory; ZF chooses to partially give up the axiom of comprehension; inconsistent set theory (part of inconsistent mathematics [1]) chooses to partially give up the axiom of non-contradiction instead. If we have to give something up, how do we decide which part to give up? You think that giving up the axiom of comprehension is a smaller price to pay than giving up the axiom of non-contradiction – but is that a subjective value judgement? Or, can it be objectively justified? (And if so, how?)

A good argument for paraconsistent logic is that relevant implication is a more accurate model of natural language than material or strict implication, and relevant implication is paraconsistent. (That said, dialetheism goes beyond mere paraconsistency.)

I'd suggest (if you have the time/inclination) reading Graham Priest's book In Contradiction. It explains the arguments for all this far better than I can from memory. (I read that book 15 years ago.)

I disagree. Both WSL and Wine are immensely useful to use some tools from the other world in your workflow without having to shuffle data between the two or adding overhead for simple tasks. I encounter tools that only exist for one (or are a real hassle to build for the other) often enough for this to be useful.

I wouldn't do development that's primarily for the other platform with them though.
I hadn’t known about the jaguar’s hardware complexity until that article that was on HN a few days ago, it’s really fascinating. I think a lot of the complexity comes from needing to cram what’s essentially a high end gaming PC into a <$500 price point. You can do it by creating specialized hardware and putting developers face to face with the metal, but that comes at a cost of complexity.
I feel the same way. It's probably because I'm 90s kid and nostalgia, but I wish web standards were taken seriously.
Yeah, that's where I knew something was wrong. There are some very genuine and useful conversations that happen in the comments at HN. They aren't universally awesome, but when I see something linked, I frequently jump straight to the comments to see the thoughts of the HN users.
I don’t think any company headquartered outside the US has to comply with those laws. It’s only if they value doing business in the US enough to do so.
I work in this field in Spain. Margins in this sector are slim, deployment is expensive. EVERYONE works with simultaneity rates, it's the only way to have cheap connections.

In fiber connections is actually not that expensive to split a fiber after a CTO, you can actually sort of daisy chain it, but you want to keep everything as standard as possible.

You consider them undesirable, but they are a critical feature for many applications.

Without browser push notifications, there really isn’t a good alternative.

The fact that opt in rates are close to 50% is probably a good thing! It means that browsers aren’t using dark patterns to trick people in to opting into things they don’t want.

I would 100% agree with you if opting out were difficult. But at least Chrome’s implementation makes it very easy to decide which sites I want push notifications from, I really can’t think of any downside given the easy opt out.
Any idea if there's documentation anywhere?

Thank you for the great writeup. It sounds like you took a responsible, valuable, and even economically viable approach, but the market doesn't want to hear it.

Here's me over 2 years ago simply quoting people who worked close to the problem:

Here's my negative scenario: self-driving is "AI-complete"; you can't really hit all the edge cases without solving AI in general, which is more than 30 years away (Kurzweil is the wild optimist and predicts 2045).

You CAN use self-driving in limited circumstances, but those limitations are precisely the ones that make driving yourself around more attractive. The expense doesn't go down as quickly as anticipated because of this. They are a niche technology for DECADES.

This looks about right, and I'm not claiming to be prescient, just basically saying what Chris Urmson and Bill Gurley already said years ago. It's weird to me that there's still so much money chasing this pipe dream.

It was a sign when Google spun out Waymo. If they really believed in the product, it would be called something like "Google Self-Driving Cars", not "Waymo".

Yes we are. I want you to keep this fact in mind: We don't know how many people are infected. We only the number from people who go in to get checked. For all you know there's a ton of people with a slight flu that are now fine. My son and myself had a pretty rough cough and fever Feb 30. Could that have been the chinese virus? We don't know. Extrapolate.

Based on everything I've read there's two schools of thought:

1. Let the virus take hold. Save the economy, let God sort out the vulnerable.

2. Quarantine and contain. Save the vulnerable, life-support the economy until the virus dies out.

US and others are doing #2.

England is doing #1.

We'll see how that plays out.
I wouldn't say 'take this with a grain of salt', but I also wouldn't brush it off as fake either. Yes, the french study wasn't structured perfectly. But such a trial isn't possible in the timeframe we're looking at.

If enough respected virologists (like Didier Raoult) and doctors in China/South Korea see some positive signals, it makes sense to prepare for the event that it does indeed help. Keep in mind, this is already being used as a treatment in the US today. They likely have even better data than we do. Or if they don't, they still feel like it's worth taking a calculated risk on.

The Credential Management API is more like a API in to the browser's password manager. A page can save a username/password/token into secure storage (which the browser can sync to your other devices) and later retrieve it. This is nice because we don't have to rely on autofilling form field heuristics.

I think the reason Mathematica hasn't "caught on" is that it doesn't look like fortran/matlab type programming that scientists/engineers are more traditionally exposed to. I find that if I'm trying to write an explicit loop (as opposed to a map or vector operation) in Mathematica I am most likely doing something wrong.

You'll drive yourself crazy trying to understand subscripts as a beginner, I would advise against getting too fancy with them unless you are fairly advanced. They work reasonably transparently in most cases, but there are a handful of situations where they are really frustrating (e.g. in With/Module/Block constructs). You can actually use them as symbols if you import the Symbolize package and Symbolize them, but then you lose the ability to "do math" to the subscript (e.g. you won't be able to use Table[] won't generate the symbolized variables.)
Deaths / confirmed cases != mortality rate

Confirmed cases make up only a fraction of total cases, without extensive active testing. Estimations say that only 10-20% are known.

Furthermore, there an incubation time from infection to diagnosis, and from diagnosis to (potential) death, so numbers are not that directly comparable.

Given above factors, overall mortality rate might be well below 1% even.
