I was thinking in a similar direction. What about an adaptive patent law? Where the duration of the protection in a particular area of interest can be set by e.g. a committee (with a strict ruleset and a big time constant of course). So when there is not much progress in a certain area (e.g. cancer or nuclear fusion) the patent protection is increased to incentivise investments.
A problem with this approach are obviously the unknown unknowns, which might prevent this system from incentivising inventions like the transistor. So this approach can probably only help with problem driven areas and not in cases where the tech innovation gives rise to new problems/solutions
It's thought to be much higher than this, I think we're expecting another paper soon that shows it more comparable to pfizer/moderna. But you have to be cautious with comparisons between the trials - the control arm was different, and the follow-up was different (Oxford were swabbing weekly).

The advantage of the Oxford vaccine is it can be stored at room temp. The Pfizer vaccine is largely being rolled out at large teaching hospitals - which means we can't get to the elderly and infirm, without risking exposure to them by bringing them up to the hospital. The Oxford vaccine would allow GP surgeries to give out the vaccine, as well as do home visits.

I'll admit that I don't know the maths behind whether a 60% reduction (which I think would multiply R rate by 0.4) will completely mitigate the increase in R by the new variant (multiply R by 1.74). It's all about a tipping point and getting the R to stay under 1, but as I pointed out above - it's difficult to compare studies using different methodologies.
Some legislation has been proposed in the US Congress to require access to research paid for with tax money (seems pretty reasonable), but so far I don't think it's been able to get past Dr. No.

HackerRank is a platform. You can design and implement your own exercises on HackerRank. We do this at our company; we design real-world problems and even test our own engineers to make sure “we” can pass our own evaluations.

I understand that at many companies, they just use pre-canned questions and all the above criticisms apply. But I don’t think this is the fault of the platform; it’s a conscious choice of the company to do so.
Very cool, thank you for the information!
I have experienced exactly this.

I worked for a company who is highly covered in tech news. The most popular stories and themes knew almost nothing about the reality of we were doing. Maybe one in five voices was correct. It was totally disheartening to the point that I completely stopped reading any related topic. Way off base.

To this day, I am frustrated by misinformation about the work we did. The internet (and general knowledge) is not intelligent.
What I am saying that hydrogen from natural gas has an incomparable economic advantage over electrolyzed hydrogen, and denying it is as silly as denying thermodynamics.

Electricity has to get tens of times cheaper for it to beat steam reforming, and you absolutely can't produce hydrogen cheaper than the energy you put into its production, most of which comes from, surprise, hydrocarbons.

And obviously, you can't produce more hydrogen than the energy equivalent in hydrogen you consume. This completely crushes whatever ignoramuses thinking that you can "use hydrogen to produce more hydrogen"
I concur with you. This debate rages on endlessly. In-person whiteboarding is the worst way to assess candidates' tech abilities... except for all of the other alternatives.
It's a huge leap forward in browser management. Not exactly a replacement for headless browsing/scraping etc, but for personal use, nothing compares. A big contribution to the "personal data management" toolbox.

In the realm of tab management, I use this one liner in console of chrome://inspect every once in a while, then just close all of my tabs:

collection = document.getElementById("pages").getElementsByClassName("subrow"); final_output_tsv = "title\turl\n"; for (let item of collection) {final_output_tsv += `${item.children[0].innerHTML}\t${item.children[1] ? item.children[1].innerHTML : "N/A"}\n`}; copy(final_output_tsv)

Substitute "devices" for "pages" to get android chrome tabs

This way I can backup all my tabs in simple, non-bookmark format and search them using python etc.
I can only speak for myself but as far as the first two the problem is that given the pressure and time constraints your success is generally dependent upon whether or not you’ve churned through similar enough problems in preparation so it’s not as much a test of your coding ability as simply pattern matching ability, which is important on some level, but not nearly as useful as, say, being able to research a solution to a novel problem and having a general sense of where to start. But for some reason we’ve equated the ability to do leet code problems with the ability to do the latter and now I’ve got to spend a significant amount of time churning through a bunch of coding exercises to prove myself instead of proving myself by doing real projects and being able to speak about them. As for take-homes, my main problem with them, other than the risk that you’re doing unpaid work, is that you often just submit your solution to the void without any chance to discuss your solution and the trade-offs you made, improvements you would implement given more time, etc. so you can imagine it quickly becomes an onerous time drain that doesn’t seem like a fair trade of time on your part if every company asks for one.
I’m able to consciously enter dreams from waking state. Basically, lucid dreaming on hard mode. Like going through sleep paralysis on purpose.

Dreams are so close to waking state, I’m always in awe when I successfully transition. Touch, taste, smell, every sense. It’s like waking reality, but with god mode.

That said, vision is really really weird. If you pull your sight into your dream body (hard to explain), then it’s just like you’d expect. It’s like it’s possible to see multiple perspectives at once, and it’s visual, but it’s all like one continuous field of view. Sometimes I don’t even really notice that I’m looking forward, backward, and from above all at once.

When I’m just playing around, I like to smash things and jump so high that I fly above the clouds, feeling the cold air above and the weightlessness at the apex. It’s no more visual primary than waking, IMHO.
I had already bought into the emacs ecosystem- it ran fine on the micros that I had been using previously.

For most work programming I still use emacs 20+ years later but that's because of muscle memory. For hobby projects I use VS Code. It runs just fine on my 32-core, 64GB RAM desktop :)
Let them solve their own problems, do their own chores far before other parents, let them have much more freedom, and stay out of their way.

At age of majority, throw them out in the middle of nowhere with a knife, compass, and fire source.
Sovereignty matters when you can’t trust there won’t be supply disruptions due to war, piracy, or trade intervention.

Post ww2 the US had no reason to be concerned with any of the above in the western world, following the collapse of the USSR this mentality was extended globally with the belief that “we’d reached the end of history”.

As of 2020 I don’t think any major power considers the risk of trade interventions or war to be negligible. The us navy may no longer be capable of ensuring freedom of the seas unilaterally.
It's unclear to me how a PID controller applies to the problem described in the article: having each client choose a subset of backend tasks in a way that will be stable for a long time. PID controllers deal with a scalar setpoint, scalar measured variable, and scalar control output and adjust frequently. How is that helpful at all in choosing this subset? It's certainly not a straightforward application of standard literature that the authors completely ignored, as suggested by siscia's grandparent comment.

> So in this example, it might be that you distribute your requests to servers based on how over or under loaded the servers are.

They had a working approach to distributing requests to servers, described at the beginning of the article. It's sessions (aka connections or channels in Google's literature) they're focusing on.

Responding also to siscia's grandchild comment:

> Or you can spin up more machines. The integral and derivative part will tell you when spinning up more machines or when to tear down the one you already got!

You're describing something like Google's autopilot, which I just linked to in another comment. A PID controller might make sense there, but it's only tangentially related to the problem described in this article.
What’s preventing them from doing this today?
I thought this was well-known? I live in Montréal and there are pretty serious regulations on wood burning stoves [1-2]. I grew up in a wood heated house and I sure love sitting by the stove, but that was in the country with extremely low housing density. I'm not super convinced about indoor air pollution, with the right stove?

Compiling Chapel: Keys to making parallel programming productive at scale (2020)
> It would be nice if leadership skills and confidence correlated with wisdom and capability.

Why? That only seems like it would be nice in a world where leadership skills and confidence are rare, and thus it's a "seller's market" for people with those skills, where people might have to settle for just picking a leader because they are good at leadership, regardless of whether they are wise. (Which is, admittedly, the world we live in now.)

However, in a world/cultural zeitgeist where leadership and confidence are commonly-cultivated attributes (like conscientiousness is in today's world: something inculcated by parents, teachers, media, etc.), most people would have that attribute, making most people potential leaders — and thus there would be a "buyer's market" for leaders. Leadership ability could be taken as pure table-stakes, and leaders would be selected first-and-foremost on their wisdom/capability/etc.

It is exactly the focus of the article, taken forward, that would make such a world come to pass.
Yes. If they didn’t, we would place them in dense grids, separated by only as large a distance to prevent them from colliding with each other when they turn in response to changes in wind direction.

Also, there’s the small matter of conservation of energy. Wind turbines turn kinetic energy from moving air into electricity. That means the moving air must lose kinetic energy. It won’t lose mass, so it has to lose velocity.

If you're 40+ and have dozens of large projects delivered in the real world for both commercial and government clients, Hackerrank and its ilk can still make you look like a beginner just because you couldn't solve one of their toy problems in the ridiculously short time available. Additionally I get annoyed when some toy SMS message problem barfed up by an online coding tester has an incorrect solution when I have a correct one.

I'm slow and methodical. I'm proud of it. My code runs for years in demanding environments without breaking and I'm famous for it, at least within my own network. My code is boring. The tech I choose is boring. The solutions I deliver are predictable.

Hiring an experienced engineer is not difficult. Can the person do the work? Can we see some examples? Will they get on with the team? How quickly can they get up to speed? Will they deliver value to you?
First you're assuming I'm a gold bug : I'm not.

Second, the person who looks like an absolute ass in this video is not who you think.

Third, there are a lot more house sessions where Ron Paul is giving various heads of the fed, including Bernanke, a healthy dose of reality check. They're all really worth watching, thaanks for pointing them out.

Finally: the only point I was trying to make is that fiat currency have been systematically used throughout history by governments to milk their citizenry without them noticing.

The USD and the feds are following a pattern that has existed since the Romans[1]: debasing currency to hide their incompetence at managing budgets.

The actual implementation vary through history, becoming increasingly sophisticated with time: the Romans slowly decreased the amount of silver in their coins hoping no one would notice.

The USG uses quantitative easing, which is much less noticeable by John Does in the street.

I understand that this is how it feels. But the natural history of pandemics is that they end.
I have steen many (near) accidents with cyclists who wanted tot conserve momentum, which really only sporty types do.

Like I said, all problems stem from that misconception. You're right that crossing 5 secs before the light turns green is one of the safest moments, but as I will happily demonstrate if you'd make it to the Netherlands, intersections need not be traffic arenas. Those solutions are halfbaked and still within an ill conceived approach to traffic.

Reducing speeds is essential, increasing predictability too, and naturally cyclists are no exception.
But unless you're already using Bazel, it's impractical to suggest "just use Bazel to distribute your builds" as doing so requires that you first migrate your build to Bazel. distcc, as noted, can be applied to an existing build regardless of the build tool used.
Former Google engineer and technical interviewer here. Google doesn't use Leetcode for interviews (at least as of 2018).

I'd be extremely surprised if Jeff Dean (at any point in his employment) would fail a SWE interview loop at Google. The Google interview is heavily based on data structures and algorithms, and Jeff Dean likely knows them cold.

Sure there's always a degree of luck, and Google errs on the side of false negatives, but there are certain people that are so high above the hiring bar that luck becomes too tiny a factor to be relevant.
My First Year as a CEO
That's a possible reason, but do you have any evidence that it's the real reason beyond it being vaguely plausible while making Apple look as bad as possible. Preventing side-loading improves iOS device security, which is just as plausible as your theory.
No I did not realize that but that said I don’t believe he is anything but a puppet to the left and to the big corporations that gave billions and manipulated what American people were allowed to see so him walking anything back is about as credible as Obama’s if you liked your health insurance plan, you could keep it.
Perhaps, but it's orders of magnitude nicer than many north american cities.
This is pretty similar to a ML Engineering interview question I got once. Basically, you get some mildly obfuscated code implementing a statistical concept and you have to tease out what the code is doing. Then you have to fix a few bugs, the variables names, and make it easier to read.
FWIW, here's an example I wrote in Python "that imitates what “compiled” FSM code might look like in an “unrolled” form. Most FSM code uses a little driver loop and a table datastructure, the code below instead acts like JMP instructions (“jump”, or GOTO in higher-level-but-still-low-level languages) to hard-code the information in the table into a little patch of branches."

Not sure you’ve fully thought this through...

Regarding your first point, in a system as I’ve described pricing for preventative care will be driven down by market forces. Especially with market pressures like price comparisons made available. This kind of care is fairly fixed in cost and has predictable demand so the business risks are much lower. Additionally government could provide tax incentives for things like getting an annual exam for example.

For point #2 you have this backwards. Insurance is meant to guard against risk. When you have situation like the current one where insurance is used to pay for routine or predictable care that whole idea of spreading the risk around with insurance is moot as the risk of costing the plan money is 100% for everyone.

Finally, fully single payer medicine is bad for all kinds of reasons as well. We need balanced solutions not ideologies.
You can use auto tab discard. I've done 1500 tabs on an 8GB windows machine.
Most of the time with countries not directly aligned to the west, the preaching is for us to sell our strategic industries in name of liberalism and "economic openness", usually spreading lies and misinformation about the company's efficiency. When it's the other way around, it's protectionism and good old Keynesian economics: China can't buy that company, their 5g is evil etc.

I know this first-hand because it has happened to my country each and every time an US backed president was elect. It's happening right now, they're attempting to sell our only semiconductor company.

The Soviet Union was destroyed from within much the same way the 2010s arab springs/ukraine and more recently also tried with HK.
You’re phrasing it as if requiring all food delivery platforms to get permission from restaurants is an unintended side effect, but again, it’s the entire point of the law.

As to the problem this solves, there are plenty of links on HN alone detailing the harm that these delivery platforms have done to consumers and restaurants both.
Which benefits?

> The output voltage across the range can vary as much as 1 Volt, but that's fine- your ear won't really be able to tell the difference.

If I understand correctly, the output from the sawtooth has a voltage offset? Can that lead to DC passing through speakers? And would the pulse-width comparator input need an equivalent voltage offset?

This is my favorite because it’s simple, but so powerful. I’ve tried to stick to this advice since I saw that comment. And I think it has made me kinder and much more willing to empathize with others and give chances.

Every time I find myself judging or criticizing others, I keep reminding myself of this comment and almost always end up with a different perspective.
Can't remember the Headline, but it was something regarding Microkernel usage on constrained devices. In case the most stripped down version of linux does not fit.
Figuring out what kind of snake bit you makes for a good plot in tv shows, but at least for North America, there are only two types of venom (vipers and corals) and coral bites are very rare, and can be treated without the anti-venom (it's a paralytic, so the person can be intubated until it wears off and can breathe on their own again).

Last I checked, the coral anti venom isn't even available in America anymore, as it was only getting used something like 3 times a year, out of thousands of doses manufactured.

So basically, generic viper anti-venom is all that is available locally. I don't know the answer to your question, but practically, it's basically irrelevant bc if it doesn't respond to the available viper av, the treatment is just supportive care.

Yeah, I encountered this. Repurposed my Netgear WNR1000 v2 with OpenWrt to act as a bridge to connect wired devices to my network. While it has served this role flawlessly for 5+ years, it's frozen in time running an old kernel. The write-up as to why they had to drop support is a good read. [1]

>But hackerrank/leetcode don't test for those skills. They test your ability to memorize solutions to trivia questions, typically things you'd never be asked to do in the workplace.

That's not really true. Most of them are variations on a relatively small set of techniques. Dynamic programming, back tracking, tree traversal, sliding window, greedy algorithms, and minimal connected tree will solve 90% of them. And those are all techniques that are occasionally useful.

Sure, some of them will have some esoteric math or algorithm that makes the solution trivial if you know it. Or sometimes there will be some confusing wording. But so long as they're not like that it's a pretty fair test.
If this is true, I am sure it's not reflective of the entire company as otherwise they won't be shipping these great products.
This is crazy. UCSF has frontline emergency doctors that have not yet received the vaccine.
> The measurement accuracy is comparable or exeeding [..] gravitational-wave astronomy

A nitpick: You are greatly underestimating the precision in gravitational-wave astronomy.

ASML's atomic scale corrections are approximately one billion times larger than the fraction-of-a-proton's width displacements measured by LIGO.

From https://www.ligo.caltech.edu/page/facts:

> At its most sensitive state, LIGO will be able to detect a change in distance between its mirrors 1/10,000th the width of a proton! This is equivalent to measuring the distance to the nearest star (some 4.2 light years away) to an accuracy smaller than the width of a human hair.
I think the difference is that units like the microKORG will come and go, but new units will often be in Eurorack form or be somehow compatible.

Eurorack can be expensive, but Behringer came out with a line that includes the Model D, Neutron, Pro-1, K-2, Wasp, and CAT—they’re all cheap, they’re all complete synths, and they’re also all Eurorack modules that can be plugged into a larger system.

Moog is also selling synthesizer modules that are actually Eurorack form, but upscale from Behringer.

I don’t have a modular synth, but it’s getting harder to avoid Eurorack.
I realize you're not suggesting this, but it unnerves me that the way to deal with a weak link in a business is to commandeer that business and blow it out of the water. That's the whole "disruption" culture. All it shows is that a weak business can be destroyed, not that a strong one can be built up.

For a restaurant to work, those basic online things have to be coupled to the production and delivery subsystems. The whole machine has to work. This can only be tested by building a working restaurant.
