This podcast episode has an amazing explanation by one of the top researchers in the field: https://www.youtube.com/watch?v=uX5t8EivCaM

The basic idea is that by making the amplitudes of the qubits destructively interfere with each other in certain ways, you can eliminate all of the wrong answers to the question you're trying to answer.
If you want to go deeper and learn a bit more about public shaming (from both sides), I highly recommend Jon Ronson’s book (the audiobook is even better) - ‘And so you’ve been publicly shamed’ which is where a lot for he details in this article are sourced from. https://en.wikipedia.org/wiki/So_You%27ve_Been_Publicly_Sham...
And how was the experince? Some blog, could learn from it?
Could you not have a separate permission based on bluetooth profile? Not all bluetooth devices are location privacy threats to the same degree.
I meant the latter - override the schedule on demand. E.g. if my schedule is 9-6 Mon-Fri, but I want to get focused sometimes when doing a weekend project, I can just click the focus button.
I’ve done my fair share of hackathons, and to me it was a fun social thing. Like a rave for nerds, but, like spending the weekend in a sweaty factory staying up all night, you’re not going to make great choices and they take it out of you. But, if you’re young it’s really damn fun.
What counts as science is results, and Sweden is flattening the curve just as well as the UK and Canada, so the system is working, whatever it is.

I mean, take a look: https://aatishb.com/covidtrends/?location=Canada&location=De...

I'm not sure why people are having such a hard time accepting that what Sweden is doing is in fact working, in the face of a pretty clear graph. Just because it appears counter-intuitive or possibly not in line with their preexisting ideas of what should be done?

There's still 5 US states without any form of lockdown (the Dakotas, Nebraska, Iowa and Arkansas), too, so you could say they're "following the Swedish model." Wyoming, Utah and Oklahoma are only under regional partial lockdowns, too. Of course they only account for about 5% of the population but it remains notable.
Then why is the white man in Iraq, Afghanistan ( bordering just Pakistan ), Somalia, Libya, Yemen, Syria - and those are just boots on the ground.

Even the "living space" that is North America, Australia didn't belong to the White Man.
Big corporations are extremely inefficient. Why does everyone want to copy them?

And why do we use all the bulky tools they produce when there are far simpler, better and more open alternatives available?
Why isn't the MWI another form of hidden variables (a supremely non-parsimonious one at that), where the hidden variable is which of the many worlds you happen to inhabit?
Find colourful substitutes, then. "Clownboat", "absolute biscuit" or similar. Might not be as succinct but they're even more colourful.
My instant thought too, obviously self entertainment, just a bit of fun. I actually can't read it any other way.
Original idea:

"OpenBSD's apparent first use of the term referred to a cryptographic development event held in Calgary on June 4, 1999."

In the current corporate "open" source world the term has been stolen and is little more than a marketing buzzword.
How much of deforestation their food would have resulted in?
It's being downvoted because it doesn't really make sense. Plants lack a central nervous system, so vegans tend to draw the line somewhere there. Regardless if we did find out that plants somehow where conscious and could feel pain we need to feed animals a huge amount of plant matter in order for us to eat them. If vegans are trying to minimise harm done then it'd still make sense to eat them directly than eat animals given there is no alternative.
My god. You're on to something. We don't have to ban gatherings, merely gatherings with particular consonants.

Can anyone answer if it is really possible to learn, make it natural to be more relaxed, more happy in everyday, without taking medicine?

I think I am more anxious than I really need, and can be more relaxed and happy. For example, I study part-time and constantly feel self-inflicted pressure to study properly, making study feel like burden than fun. Or I worry too much about minor issues like broken pump in the garden, finding a kindergarten for my baby, etc.

In reality, I am doing fine: I have a good income, great wife and son, no major health issues, I already have a degree and my studies of maths are more for self-growth with room for failure.

I understand it logically that I do not want to treat my studies as obligation and can enjoy the process, that I want to be more relaxed and resilient to small problems. But plain understanding does not turn me into a more relaxed personality, as it does not pierce deep enough into the brain. Is there a way to re-wire our brains for better attitude and happiness?
ive been enjoying this video series, i especially liked the video where he built his own alternator from scratch, i found it extremely educational.
The 757 was the last bird drawn by hand on vellum, and the last with a wooden mockup. We mostly used calculators on formulae pulled from the Boeing Design Manual (a treasure), or derived formulae as needed. Some of the draftsmen did calculations by drawing geometric shapes and measuring them, which I'm sure is a lost art now.

We were mentored by greybeards who worked on the B-47 and 747, and sometimes would still use a slide rule. I received quite a wonderful education from those guys.

I was the first flight controls engineer, that I could tell, who stole time on a PDP-11 to much more efficiently do my work beyond what was practical with a calculator. (I was called on the carpet for that, the manager of the computer center wanted me censured for it, but my boss's boss's boss went to bat for me and told him to fork off.)
None. For whatever reason, I just don't care for the taste of either coffee or tea.

That isn't a health thing either, I simply csn't understand the appeal of these types of drinks and have never liked the taste of any I've tried.
Yeah this guy is so bad.

Amazon thrived because of the dotcom bust. Not the bubble but the bust, which took out their ~entire deeply uneconomic competition.

There's no better time to create a sensible business than when all the non-economic actors and their VC donors are taken out. Infinite money makes it impossible to do so because you'll be undercut by "blitzscaling" and other creative forms of capital destruction.
Which raises the question for the surviving start-up, with a lean operation, customers and profits, why this company would need and want VC money. Unless, of course, the only measure of success is VC investments.
Yes! How come this isn't higher up in the list? This is one of the best pieces of education I've ever seen. Absolutely wonderful.
Wouldn't one just use coalesce()? e.g. coalesce(Field, 1) = 1?
After reading some of them, it became obvious nationality and the race always creates a funny conflict :)

Google provides a platform for advertisers to use. The sophistication of that usage, however, is up to the marketers actually using it. At a small scale, it's relatively easy to bootstrap the type of integrated infrastructure and execution required for sophisticated campaigns. But at scale, marketing programs require so much people-coordination (between various internal departments and external agencies) that relatively few firms end up in an operationally mature state to attempt to integrate sophisticated technical and data operations as well.

Anecdotally speaking, the morass of font licensing[1] is likely to have an order of magnitude more attention in a typical campaign than something as seemingly critical as the actual ad targeting or frequency caps.

Unfortunately not. DDD is a design concept on how to match the business domain in source code - the design step is language independent and the practical implementation is very business dependent. I'm also keen to find a good practical reference, but can also understand why there might never be one. The book above on F# is very approachable, as F# in the predecessor of TS and the first half of the book is even language independent. Learning some SOA (service oriented architecture) terminology will be of some help as well.

I highly encourage you to not solely stick around JS/TS for patterns. For me, JS/TS is the "most" multi-paradigm language in usage to date, thus is not one of those languages that needs to be written in a certain way. Other languages can give you patterns more clearly and those are for the most parts adaptable to JS/TS. Haskell made it click for me on how to model with types, Elixir has the interesting concurrency/resilience pattern with supervisors etc... There are also good JS libraries whose usage still feels like programming and less "using a framework"-like - RxJS has an interesting approach for events/subscriptions and I feel like redux-saga showed me a very good use case for generators.
Ask HN: Moving into System Engineering
Hi all,

I want to ask for advice regarding getting a career in system programming. I have about 7 years of professional working experience. Last 4 years has been in the area of full-stack development (Typescript, MySQL, AWS, etc). Prior to that, I spent 3 years working on Android OS, but more on the frameworks layer (Java, C++, C), while also having some level of exposures on low-level Android code (i.e. HAL) and Linux kernel programming.

I've been really interested to have a career in a low-level system programming, especially in Linux kernel. But there are some obstacles: (1) Other than hacking as a hobby on the side, I don't have a concrete portfolio in system programming that I can show off to get an interview. (2) I'm currently based in South East Asia (Singapore), and it doesn't seem like there's that many system programming positions here?

I'm very tempted to take a few months off, to focus on building a portfolio around system programming. My questions are: (1) what would be a good project to work on or OSS to contribute to land a system programming job? (2) what career prospect is there for Linux kernel development? (3) what are the recommended system programming language with good career prospects? (4) how hard it is to get a remote system programming job? (5) is it a good idea to get an internship position to get my feet wet vs. just building a side project?

I'd really appreciate it if somebody in the industry can enlighten me :)
There is a tutorial about that https://www.youtube.com/watch?v=UPgxnGC8oBU
> As soon as the author started talking about eradication, he left the scientific concensus.

Something i have read is that there is a split between epidemiologists and public health experts. Epidemiologists accept that we can't eradicate, and so have to manage the outbreak. Public health experts still think in terms of eradication.

My understanding is that this is an inertia thing. Public health experts have spent decades focused on eradicating diseases, so that's the only way they can think. Meanwhile, epidemiologists only study diseases that have escaped containment, so that's the only way they can think!
Unrelated to your comment here but a while back you mentioned you liked some Space Cadet keycaps I had, but they are usually only available via a group buy.

Why on Earth is an interesting question. Why in space might have some reasons though ;)
Very impressive! Callibration took a fair minute or two but I didn't have to do anything complicated like show it all the different poses.

Fun couple of games. I had trouble getting it to recognise down but I think that's because I can't bend my neck forward and keep looking at the screen (glasses) to see the snake moving.

Also I am definitely team: Screen edge should wrap around!
I think only excess mortality makes sense. ICU admissions depends on ICU availabilty and has a ceiling when the system nears saturation so it's not very comparable, a country with very few ICU will have low numbers.
> madhadron doens't know what he's talking about.

Not sure why you're saying this when you end up saying pretty much what madhadron said, i.e.: "To be excruciatingly precise, it's a ray in Hilbert space"

I get that madhadron doesn't explain themselves but still... There's some irony here.
Thanks for asking! but unfortunately I haven't written anything up about it, but informally I can share that it's really benefited our health and even finances. Eating beans and rice every day and not eating out is very cheap. I buy most of our food in bulk online or from local farms - e.g. just got 50kg of chickpeas in the mail and 20kg of string beans from a farm. We also avoid eating oil for health reasons
getting an SDR and learning about RF would be a good start
> This very idea lead to several prominent Stoics to commit suicide, because might as well hasten my eventual ceasing of being?

To put a name to what you speak of, Seneca was forced to commit suicide by the emperor Nero. In letter 58 (titled 'A conversation about Plato'), he posits this view on whether it is appropriate to reject extreme old age (I'm not fully on-board with what he's saying; still forming my views):

"It's the next thing to cowardice when one merely waits in idleness for death to come, just as one must be excessively devoted to wine if he drains every drop from the vat and guzzles even the lees. The question, though is this: is the last part of life really the lees, or is it the finest, purest part? That is, provided the mind is without impairment, the sense intact and of use to the mind, and provided the body is not crippled and moribund before it's time. For it matters a great deal whether one is prolonging life or prolonging death. Yet if the body can no longer perform any service, why should it not be appropriate to release the suffering mind?"

That said, I see where you're coming from; we should indeed not take any of the school's thoughts to senseless extremes. We're lucky in that we can sensibly cherry-pick. But I wouldn't talk in super generalized terms as "The Problem" with X or Y school of thought. Of course they are riddled with their share of problems; we need to adapt them to our present conditions—after all, they were written more than 2000 years ago!
2.2 * 30 + 15 = 81MB

For people with 200MB & 500MB data caps (which is a surprisingly large number of people), this is a significant amount of their data allowance.

These are likely to be people that are still required to go out into the world and work, so are still using their data instead of wifi, and thus higher risk.

It's easy to forget when you're on 10GB+ data plans for years just how many people are not.

I agree, being bootstrapped, and lean, is one huge advantage right now. And being able to live from your own company, without any investors, is more than a lot of unicorns achieved so far.
One need only look at the dismantelling of our strategic stockpiles of respirators following 2002/2003 SARS to find a relevant example today. Stupid choices are inevitable in a political climate that looks at any spending on human life as a costly line item to be eliminated.
I maintain such a project with many dependencies which I also maintain separately. Yes it can be a lot of extra work to publish but this argument is based on the assumption that dependencies need to be changed constantly and this assumption is wrong. There should be pressure to design dependencies in such a way that they are modular and don't need to be changed often - This unpleasantness associated with updating deep dependencies is good and necessary. These should rarely be updated, if they need to be updated often, then they were designed incorrectly.

Many of the dependencies and sub-dependencies which I maintain are several years old. They are small enough and stable enough that they basically never need to change.

If I need to update them (which is rare), I may need to do a cascading update of multiple dependents and this can take a while but if I have to do this big update only once every 6 months, it's totally worth having them in separate repos.
Word on the street is they would be able to kill them properly if the employees were there.
I've been obsessed w/ r/coronavirus and panicking for weeks, I'm starting to feel disassociated from it, like I know it's real but part of me thinks "don't worry, won't happen to me".

Part of that is that I'm in rural utah and we have 40 cases in a huge 3-4 county area w/ 100k+ people. It's not like I'm in NY where I can hear the sirens all day. I'm also getting tired of frozen food and home-cooked dinners. We do order delivery or drive-thru 1-2 times per week, but I'm always paranoid when I do but I feel I'm getting more 'comfortable' and less paranoid, which could bite me in the ass as I'm higher risk (obesity, 40, sleep apnea).

probably part of it is also the longer days make it go so much slower, and even my introverted self wants to get out of the house and do something besides this all day everyday for the next year.
Some dams use this with their generators being situation in the valley below. I see little point to do this unless you are restricted by some other factor, for example if you are a flat country with no access to natural reservoirs or vertical drops.
hmm anyone else get this:

"Sorry, this content is not available in your region."
Very very few things can be properly summed up in 280 characters, and most of them aren't important things. Don't forget that your brain cast its own prejudices and points of view over everything, it's very easy to misinterpret a 280 char long text, not so much when you read a 500 pages book in which the author describes every little bit of his thought process.

There is also a huge issue where people get tricked into thinking familiarity = knowledge. Reading tons of 280 char texts seemingly synthesising complex ideas in "single bite" portions is a problem, it makes you think you know something when in reality you just absorbed 280 characters of "facts" without any context or substance, it doesn't better you. Especially on twitter, which must be the most polarised and polarising medium out there. It is level 0 of knowledge acquisition.

The cosmic inflation. Yes, the universe is smooth but how is that enough to justify this unimaginable expansion? There seem to be no proof or possible experiment yet the scientific community apparently accepted this theory with its abrupt start and abrupt end, only secondary to the big bang itself in its scale and energy.

This is nice. A couple of days back I was thinking of a utility where labels are created automatically. It uses meta information like:

* How many emails I get from a sender

* From mails' subject

* Which similar mails I open or not.
I honestly wish I could have come up with those substitutes. I have a great deal of trouble in independently finding language that sounds like that since no one I listen to/read talks/writes like that. I'll have to jump down the rabbit hole of finding people that use that kind of language for more substitutes.
One of my favourite quirks of English (that obscure language from a small island) is:

"If it were up to me..."

That's the correct grammar for when you have a conditional argument. I know that a lot of Americans don't know this rule at all (especially musicians) but I suspect that it is a regional thing and not strictly US vs. Brit.

Note that if the conditional reflects something that really happened, then you use was as usual.

"If I was wrong by saying that..."
LAX is the port of entry for most of the asian world in the US and LA is doing far better than NYC due to leadership choices alone.
Taking a critical look at one's own meat consumption can be enlightening, because it is something that we often take for granted. Do I eat meat because it is necessary for my health? If not, what are the reasons? How is the meat that I'm eating produced? How long do these animals live compared to their natural life span? What is the environmental cost of animal farming? Etc., Etc.

I did not find convincing answers to these questions, so I stopped buying and eating meat.
Kudos for trying to find a sensible solution, but most of these disputes aren't about determining which geographical area a person and/or their ancestors stem from - that would be relatively simple to resolve with sources which are typically available.

Modern nationality is a highly complex topic related to not only geography, but also politics, language, religion etc. Often a dispute is not about providing information on a historical figure, but about "claiming" important people for your nation so that your collective "historical importance" is increased.

> South Korea, which so far has managed the pandemic better than any other country

Actually, Taiwan has done better. They've had no local cases for 14 days.

https://taipeitimes.com/News/front/archives/2020/04/27/20037...

They did it by ignoring the WHO's advice and locking down early and then aggressively containing all cases, preventing a general outbreak.

They've been pursuing this since December 31st, when they issued a warning to the WHO about what was going on and locked down. The WHO ignored them.

https://www.taipeitimes.com/News/front/archives/2020/04/12/2...

They've taken 4 months to get to no new cases. From a much better starting point. With a much smaller population.

I'm very skeptical about what this guy is advocating.
These are some good points. Yes, the scenario was very optimistic :)
Thanks! This is something to think about.

Intel Graphics Reference Manual (10th gen)
If you look at [3], you'll see that it has been simplified and "manager" isn't required anymore - if you are flexible in your working hours and earn 120k+ (which isn't that much - if you work in tech or at a bank you'll likely earn more) the company can agree with you to not record working hours (there's still legal limits to how much you can work, of course) - this is relatively new, since 2016
