Ask HN: Y Combinator S20 and Covid-19
Does Y Combinator plan to change approach for S20 batch amid CVOID-19? Like online interviews, as travel ban from Europe will make it hard for many founders to be on them. What about 3 month program?
> why the higher-level syntax has never made its way to lower level ASM has baffled me

Traditionally assembler was both for bootstrap processes and for the older heavily resource constrained systems, so there was a lot of emphasis on making it as simple to parse as possible; opcode first, then arguments, because the opcode is first in the byte stream of almost all variable-instruction length systems.

And of course no support for complex expressions, so no point in building a full mathematic expression parser.

Then there's the question of which add instruction you want. The vast proliferation of instructions in things like AVX gives you "VADDPS" and even "VFMSUBADD132PD", which expands to: https://www.felixcloutier.com/x86/vfmsubadd132pd:vfmsubadd21...

Cool, thank you very much!
I know that they cannot be local. My point of view is "just let them be global, build theories from there", global hidden variables don't interfere with any intuitions about the world for some reason.

This sounds like Spark's register windows https://en.wikipedia.org/wiki/SPARC#Features

I got it from a very reliable source, someone who was involved in evolving that hardware, that this feature caused Sun "an awful lot of pain" (his words, best I can recall).

My understanding is that it greatly destroyed the ability to do out-of-order execution, which was on top of the original designer's failure to understand what the compiler could do with inlining that would largely negate the value of this. From what I've read over the years, the Sparc hardware guys didn't talk to the compiler guys - a trap the designers of the DEC Alpha very carefully did not fall into.

Since this is a teaching project, I'm sure that feature is fine, but just saying.
Yeah, I remember reading something similar years ago. But I suspect with the proliferation of "craft tonic water" there may be some "flavours" that don't contain quinine at all.

And 6L of tonic water is... quite a lot.
Better be an optimist and wrong than a pessimist and be correct or something like that.

For me the interesting part is the unexpected. So if you model the perfect world, a "solar punk world" for all I care, I would expect to be one or two "buts" in there. Nuance has always been a requirement for good literature in my opinion. The reverse is true for cyber punk. I don't know of a single example that just describes the worst dystopia immaginable. There is always the counter balance with something that warrants optimism.

So I would argue it to be the same genre group to be honest.

Still, from the description of solar punk or "post-cyberpunk" sounds just like a template for many horror novells that happen to play in the future.
> They basically assume the number of confirmed infections 14 days ago better represents the real number of infections on that date than the number of confirmed infections today.

No, they assume it better represents the real number of infections present long enough that someone would have died of them if they were going to. Which may also be a problematic assumption, but is a very different assumption from what you describe.
You joke about firefighting but you couldn't have picked a worse example. That is one of the major misconceptions people have about required local services - it's not required.
Decent link, thanks.

It doesn't surprise me that having more visible registers and doing a good job of register allocation in the compiler is a better strategy (i.e., both more efficient and more flexible), but doing so means you are not so close to the metal. From the point of view of an efficiency feature that doesn't ask for complexity in the compiler, I see some appeal to register windows.
I guess I'm lucky enough to know one of these 27 people.

Reminds me of when Delphi was still popular. Lots of UI kits that let you have sleek UIs. Qt attempts to give you this sorta freedom from what I can tell.
You can also have nice dialogs by using dialog/xdialog/zenity. For example, you can use named pipes and get a nice progress bar:

mkfifo progress
cat progress | zenity --progress --text='progress' --percentage=0 &
echo 10 > progress
sleep 10
echo '# Done!' > progress
echo 100 > progress

I agree that sriking the correct middle ground, solution wise, is close to impossible. But isn't it way riskier for a political career to do nothing by now? The public, in my impression, would take it better if measures tended on the heavy-handed side of the spectrum as compared to the oppsite.
The Purpose paragraph you quoted from https://github.com/kickscondor/fraidycat/blob/master/LICENSE... is far from “the only real content”. That paragraph is a statement of intent, not a compression of the details into one sentence. It’s not supposed to be unambiguous. The next seven paragraphs on Acceptance, Copyright, Notices, Excuse, Patent, Reliability, and No Liability are the actual rules of the license.

The Blue Oak Model License aims to be closer to the MIT License than to the Unlicense. The Unlicense releases the software into the public domain, which means, for example, that someone who makes a derivative work could release that work under a proprietary license. In contrast, the Notices section of the Blue Oak Model License, just like the third paragraph of the MIT License, requires derivative works to be released under the same license. I would say the Blue Oak Model License uses the idea of “freedom through self-imposed restrictions” more than both the Unlicense and the MIT License.

I think the biggest difference between the MIT License and the Blue Oak Model License is that the MIT License doesn’t mention patents, which (some lawyers think) could allow authors of MIT-Licensed software to sue users for violating their patents used by the software. The Blue Oak Model License’s Patent section closes that loophole.
You just answered your question. You didn't like the answer and that's the only problem: your problem.
I don't think so. Programmers should be taught what is going on under the hood if they're learning system languages like c/c++/rust
Essentially you go from recovering patient to 20,000 therapeutic doses in 60-90 days.

Note it is not a vaccine - a vaccine is something like part of a virus that then drives an immune response ( body evolves antibodies against it ) - here you are taking an antibody sequence you know works and directly putting that in the body and genetically programming the body to make it.

Here's how:

- find and clone the patients own antibody that allowed them to recover.

- deliver that antibody in nucleic acid form to new patients so they can make the antibody themselves.

The idea is to be able to produce enough doses quickly enough to protect front line staff in the containment phase.

As the antibody has already been discovered by the recovering patient, you can use single cell screening and cloning to retrieve the particular antibody gene.

The second step avoids many many months of building and scaling a protein manufacturing process ( though manufacturing steps still exist ).

It's a new technology and so carries some unknowns - but in the case of pandemic then you could argue these are justified.

There has already been a proof of principal run through and a number of companies were able to deliver proof of concepts within the timescale. The next question is how well these work in people.

> There was a potential problem. However the companies and government departments that were affected had started planning in the early 90s, and they prepared during the decade.

I can point to several huge companies who did nothing until 1998 or even 1999. The media scare helped with that (priority, money) a lot.
Light-induced a-FeOOH coupled with photoreduction yields 25x more H2 than TiO2
That’s less than one bed per million heads, country-wise. I think the militaries of many rich countries can do the same today, scaled for population (they will use containers, but that’s what was used for that Chinese hospital, too)

I also think many countries could do something similar (ignoring technical progress) in 1918, given they had had ample practice in world war 1.
Could it? We often no longer have random factories waiting around, ready to be repurposed. Neither do we have well functioning internal supply chains for the needed raw materials. I don't think people truly understand just how dependent any given country is on global trade (and especially Chinese manufacturing).

Does anyone remember "The Girl Who Was Plugged In" by James Tiptree Jr?

Listen Zombie, believe me. It was a real cyberpunk novel in 1970s.
It was World War I raging at the time, how more densely packed can you be than a bunch of soldiers sitting in a mudded trench?
Also, they have to think systemically, not individually. Basic game theory. It's preferable, from the perspective of the government (and society - i.e. Pareto optimal) to avoid any panic and shut down the country only to the extent necessary, in an organized and orderly fashion, rather than stoke up fears and panic and "each man for himself" mentality. Trump seems to be walking the tight line (intentionally or not) between making bold, highly visible moves - banning flights from China, now EU - and avoiding moves that actually matter - closing borders completely, enforcing isolation in communities - which might help stop the disease but also would definitely crash the economy (the real economy, not just the stock market as now).

Plus, they have very little skin in the game - literally only (re)election... but they have bank accounts in Switzerland & the Caribbean, vacation houses in low-population areas, priority access to medical services, private security & transportation services... they'll be fine, whatever happens.

If you only act when you hit the peak, any measures will be moot. Countries need to act now to reduce that peak and flatten the curve.

But sure, why not letting thousands of Atletico supporters into Liverpool, while Madrid has 1k+ cases. Was it also a "drastic measure" to play a football match behind closed doors?

We don't have resource constrained systems now. I doubt parsing asm ever took up much anyway.

I'm not suggesting we permit complex (ie. general opcode combination) expressions. I deliberately never suggested it.

As to straighforward FMAC-type instructions, that's even clearer in my notation: a += b * c

But As for the proliferation of those add types you linked to, OK, possibly valid, but how much of this are you going to be manually writing compared to the very mundane style non-simd non-packed instructions? My guess is very little as you have relatively few number of such instructions (although they're doing a great deal of work over streams of data, but that's not relevant).
counterpoint: what percentage of the world population has access to that?
Sure. I'm not claiming that msft was wrong to make that attempt. It just illustrates what a failure case looks like, even when it's a good risk.

Correction taken on Android timing.
Python is far more promiscuous with Exceptions than languages like C#; they're not just used for "truly exceptional" conditions (see things like StopIteration or GeneratorExit).

Different languages have different attitudes to this and that's reflected in their APIs. This will naturally affect your choice of language when designing a system, depending on your tolerance for failures, your demands for robustness, or your definition of "exceptional".

Viruses don't live long enough to survive ocean shipping, so as long as the (tiny) crew is kept isolated, ocean shipping is fine. Within a country, it's not hard to disinfect a truck and keep the driver isolated.

Of course, if the originating factory is shut, then you're screwed - but that's true regardless of trade.

Also worth noting: it takes a tiny number of people to produce tons of food (calories). Maybe not true for artisanal salami but for bulk basics.
Not only viral pneumonia though.

According to a professor, specializing in pandemics, I heard interviewed while the outbreak was still focused mainly in Wuhan, many ultimately get killed off by bacterial secondary infection.
Encouraging in some ways, under the horrifying circumstances, with the catch that in many parts of the world that secondary infection will be caused by multiple resistance bacteria.

I'd say this pandemic is going to be by far the biggest single consequence post to date for the antibiotic resistance problem, despite being driven by a pathogen that was never sensitive to the antibiotics.

This is false. Clinical management of the syndrome is purely supportive. There is ongoing work toward a variety of possible treatments - cytokine release syndrome can also result from a garden-variety flu, and as a side effect of some other therapies - but there's nothing outside an early experimental stage thus far.
It never works like this because then it would take hours to set your pincode. What actually happens is the disk or each file is encrypted and the key is protected or unprotected, depending on passcodes.

On iOS the files are encrypted so that some of them become available at boot, some the first time you unlock the device and some only while the device is locked.

On modern devices the key protection is managed by the security chip/Secure Enclave zo it can both attempt to limit attempts to a number of times and prevent people from brute forcing the key because only the chip can run attempts which are purposely made slow.

Typically Cellebrite like tools bypass the lockouts but still have brute forcing limited so it only practically works on short or poor pin or passcodes.

Still, it’s unlikely a device is going to remain safe for 15 years, if the adversary is patient it’ll eventually be unlocked; technology advances and bugs are found in everything.
I do not, unfortunately :(

Non-determinism requires some kind of RNG which is truly random (TRNG), right? So the next value can't be calculated from the previous one. This means all values of truly random RNG just exist as we don't need to iterate all of them in order to calculate what's next? So truly random RNG is just pre-determined instantly from step one and RRNG is as pre-determined as TRNG?

The problem wasn't about the conduct of the Biden's, it was Trump (allegedly) telling the Ukrainian President the Ukraine would only receive already allocated military aid if the Ukraine started investigating the Bidens, supposedly to get Joe Biden into at least political if not legal trouble that Trump could then capitalize on in a re-election bid. Whether or not the Biden's did anything wrong (and so far the have been cleared at least legally, tho I have to admit there is a stink of nepotism in my opinion) wasn't the issue, the problem was if Trump, the sitting president, abused the power of his office for personal gain by threatening to withhold public aid money allocated by congress.

I think that's a little overblown. It's true in the strict sense that general purpose manufacturing capacity was more common and the production of many goods was more distributed, but on the other hand that manufacturing capacity would have been very limited in capacity and scalability. I'm not convinced it would actually make a big difference in practice.

>The economy would collapse because the incentive to outperform would be gone.

You speak as if huge chunks of our society haven't been socialized with great results. You want to re-privatize the fire department, so they have more incentive to put out fires? Privatize the police force, so they have more incentive to stop crimes? It's not so straightforward as "private enterprise = proper incentive structure" - it's possible to engineer incentive structures with better outcomes than the free market.
Yeah, just to be clear, I think there's no chance in the US either. I just saw something that said we actually only have 45k beds, and they're mostly already full anyway. Plus there's no chance we're going to be able to keep this clamped down for months. We'll be overwhelmed in weeks.
Did they test random people or only people with symptoms? If the latter then your distribution is heavily biased and a 10x difference is not an outlier, it's the expected outcome.
I don't think this is correct. There were some indications earlier on that some people can get Covid-19 more than once but the cases appear to have been relapses rather than being infected more than once.
