It is am extremely stark example of the value of maintaining manufacturing capacity in your country. Korea can makes tests, so they have tests.

Seegene, a company that makes Covid-19 testing equipment is in Korea. They just needed approval and to ramp up manufacturing. For most countries, like the US, we don't have the manufacturing ability anymore, so we have to go beg and buy tests while we figure how to make again. Seegene alone has been responsible for 80% of the tests in Korea.
I hope they consider adversarial use cases.

Authoritarian countries may give fake test results to people they don't like in order to find their whereabouts for the past two weeks, for example.

In the end, people should be in control and it should be obviously simple turn it off systemwide (not buried in Settings > Privacy > Location > System Services or whatever).

i would say CL for serious work and scheme for what it teaches you. I would say that the principle of scheme with a few well chosen primitives that compose into efficient abstractions is something I will forever carry with me.

Common lisp is amazing as well. large and full of warts, but incredibly practical and battle-tested. if I were to write a larger project from scratch I would either pick SBCL or chez scheme, even though I myself am a guile weenie.

Ask HN: I got rejected by all the US colleges I applied to. Now what?
- I got a low ACT score (28). Took the test only once.

- I applied to all the Ivy’s plus half a dozen other private undergraduate colleges. Got rejected from all.

- I assumed my ‘other’ credentials will make up for my low ACT score. I guess i was wrong.

- I scored straight A’s in my A Levels.

- I co-founded a company that has been successfully running for 3+ years now.

- I play a very popular sport at the state level.

- I expected to at least get into Babson (for its entrepreneurship program). But nope.

- Not an expert yet, but i can code (python, javascript).

On the plus side, i have saved 100,000+ USD that i can use as seed capital if i launch my company.

I don't know if it would "destroy" Harvard, but it would definitely make prestige more "merit" based (merit being in quotes because its definition is highly contentious). If Harvard were catered to all students with capable ability and/or drive then we'd have a new class of highly paid professionals. The problem as I see it is with funding. Will the state by itself be able to uphold the funding that supports the infrastructure and academic resources researchers and students need to succeed? Those who were admitted to this merit-based system may contribute, but that leaves room for the incentive-based system that we have today

I’ve always thought the distribution issue it’s the largest problem for alternative fuel vehicles.

Driving to Los Angeles from San Francisco is extremely difficult for either a fuel cell or ev vehicle (that’s not a Tesla, and it’s also true for cng vehicles). This is admittedly not a daily use case, but highlights the issues with refueling.

It’s hard to see either technology being our primary transportation mode without solving some of this. EVs have an advantage for fuel availability, but issues around fueling time.

They took a long time to decide it was a national priority. At the point when Korea started heavily ramping up its testing program, most Western countries took roughly the same approach they took during SARS, where they contact traced and tested only the few cases they knew about with the expectation that'd be enough.
If you compare it to MERS/SARS it is actually less harmful (at an individual level) than those. But of course this ends up meaning more harmful at a collective level since it takes a while for people to develop symptoms while still being able to infect other people.

YES

Since the Google Maps 'Allow 24/7 location tracing? Yes/Maybe Later' popping up once every other week, it is pretty clear that at least Google is willing to push surveillance as hard as possible. Once they have GACT built, deployed en masse and somewhat trusted by the public, it is not hard to infer they'll be willing to push any number of dark patterns to make it the de-facto reality for 99% of the population out there.

In summary: Yes, they can push any shit right now on your phone. No, they don't just push it yet because they are afraid of public / internal backlash. Yes, they'll do everything in their power to boil the proverbial frog and gradually reduce the backlash potential, and will eventually push the most invasive surveillance they can possibly conceive. And they are pretty imaginative.

Medium term bet: Within a year, Google will change GACT from opt-in to [de-facto] opt-out. For example by nagging you every two weeks: 'Protect your grandma life? Yes/Maybe Later'.
Perhaps I'm missing it, but the only reason I can find in TFA for using coroutines here is that it's the most intuitive way of writing this FSM class.

Is it really more intuitive than something like:

class FSM:
def __init__(self):
self.current_state = self._start
self.stopped = False

def send(self, char):
self.current_state(char)

def does_match(self):
if self.stopped:
return False
return self.current_state == self._q3

...

def _q2(self, char):
if char == 'b':
return

if char == 'c'
self.current_state = self._q3

self.stopped = True

...

(Using names 'send' etc. from the article just for easier comparison.)

This is basically the same except not using co-routines, and I don't see what advantage using them brings?

Not using them has a clear advantage (IMO) that we don't have to initialise each state (`_create_q2()`) - which just seems strange to read, and a recipe for forgetting ('I just added a state for this, why are we still seeing this error...') since it essentially means a state is 'declared' in init, and defined in a method. But this is Python, and a compiler won't complain. Neither will your linter know^ that you should have called that method in `__init__`.

^(OK, you _might_ have a check that it's used anywhere ever, but there's a lot of good reasons for not having that - library code, abstractions, linter not clever enough to work out you have called things in a non-straightforward way, etc.)
This is the kind of response that comes from, and please excuse my language, someone who doesn't know what the fuck they're talking about.

There is barely a safety net. There is barely any institutional support for innovation. Accessing either is a competitive process that is purposely obfuscated to reduce costs. The downside involved in preparing for and executing on innovative ideas is potentially lethal for the individual, even if it might be incredibly advantageous for society for even one person to be successful.

If you want people to fly high, you start by putting a trampoline under them, not a trap pit of crocodiles. Things are as bad as they are because the people with the means to push us onward do not understand the problem.
Afaik, the shortage in US is mainly of raw materials and commodity items like pipettes. How did Seegene ramp up its raw material pipeline so quickly. Really fascinating success.
Maybe force the lawmakers to include a text explaining the "spirit" of the law, also including indicators to the law effectiveness. For example, a law is implemented to bring down then "car accidents per million" indicator. If one year later car accidents are the same or more then the law is scrapped.

What you propose of robo-lawyers and law as code sounds as the script for a futuristic Kafka's "The Process" as an episode of Black Mirror.

For those who may be unaware: martensitic steels encompass all standard tool steels, e.g the ones used for knives, springs, dies, files etc. martensitic means hardenable.

Being able to 3D print these into arbitrary shapes vs machining them will likely be of the most value for parts that need to be light.

I’m curious that they mention wanting to print low alloy steels, since low alloy steels tend to be relatively easy to machine. I’d have expected more interest in higher performance steels. Can anyone comment why people would want to print in low-alloy martensitic steel?

The article doesn’t address this, but, the martensitic transformation typically changes a part’s volume by ~4%. that can make it difficult to make precision parts unless final finishing happens at full hardness. I wonder if this process results in direct production of martensite, or if the parts still need heat treatment.

To me, this is a very interesting process, but doubly so given the possibilities of generative design. For those who want to visualize why you might want to 3D print steels vs machining them, think more about brackets and support structures than turbines, and take a look at some generative design parts.

At least for higher education, I think it's a little more difficult to scale than this piece makes. Higher education has a very entrenched culture of obsessing with fundraising, accumulation of prestige through factors tangential to education quality, and exploitation of undergrad/grad labor. My state school tried to 'build' enrollments in it's historically competitive STEM majors and I just saw these problematic factors become worse; increased reliance on underpaid student TAs, with additional funding being dumped into band-aids such as tutoring programs fractured between departments and stress relief fairs. For higher education it needs complete cultural or policy reform to focus on educating and eliminate cruft, before we can start building it out.

Here's a guy who thinks of his kids as products. And things he does and they do as features.
Yes, exactly. It's tempting to try to compute coefficients X weeks in, so we can forecast X+26 weeks in the future.

But the coefficients aren't fixed. Coefficients change drastically due to public policy, individual actions in response to news and social media, culture of local communities, degree of compliance with public policy, travel between regions with different rates of infection, etc.

So you're not fitting a curve to the data, you're modeling dynamic human actions which are not nearly as easy to forecast.

Begin asking around in your dev circles.

Keep track of how many you ask, and how many of that value even know of it, and further, how many who know of it regularly utilize it.

Then you'll have some actual factual values with this to reach any conclusions. I predict you'll find that the "knows about" group is, maybe, at best 15% of the total, and the "uses it regularly" group is, maybe, at best 5% of the group that even knows it exists.

Coming to consciousness in a world of people that gets angry with you when your thoughts challenge them too much (and you were just trying to set context), withhold the majority of social experiences and needs from you, and decide you are magic but to be subjected as fantastically exploitable because they have social control is hard. Add that they simply don't know what to do with you, how to support or challenge you, and decide basically that you're not worth the challenge you present. You have to not only survive facing bigger challenges and thoughts without the support and canned solutions most receive but you have to do it largely alone with a smaller set of your needs met.

I suggest you aren't surrounded by idiots but by people that are normal and mostly doing their imperfect best. The idiots are on the far other side of the bell curve and there are fewer of them. Imagine for a bit trying to survive as them with as little understanding as they have and the limited scope of perspective. You'd struggle and develop heuristics and tribes to survive too. I don't expect this to help much but perhaps you can find some grace when you interact. Speaking for myself, the frustration and anger I used to feel on that interface was corrosive to myself and I prefer the increased peace I have now.

But if you want to play civil servant lawyer and argue "any failing part of the British healthcare system isn't really the NHS", go for it. From the international perspective nobody cares. Public Health England is the Department of Health is the NHS is the government. How the government divides up responsibility between variously branded bureaucracies doesn't alter the overall outcomes, nor the reasons for them. The UK centralised all CV testing in a bureaucracy that was quickly overwhelmed, didn't scale up, didn't involve the private sector and didn't react quickly to need. Privately run healthcare systems managed all these things.
It’s really hard to convey tech debt cost. Probably many systems have a ton of problems adding 5% to every feature here, 10% there, bad DB design from early in the project that makes a bunch of actions far riskier than they should be (but until it breaks several times no-one cares and if your devs are putting 3x as much effort into those dangerous operations and know what they’re doing, it won’t), and so on. Communicating that in a way the business folks will care about is hard, and the full costs are difficult to account for.

[edit] hell, communicating that in a way the weaker end of technical managers will care about can be hard, for that matter. If they came up “doing it wrong” and are of a certain mindset, good friggin’ luck.
