I'm a strong supporter of this sort of research but our lack of fundamental understanding of most life processes does not inspire confidence we'll crack this puzzle soon.

More likely, through use of bioinformatics to customize chronic disease treatments, we'll get another few decades of average life expectancy over the next century.
Nope. My work Google account didn't have my phone number but did have TOTP setup.

I could set up TOTP on my personal account today, again without linking it to a phone number, but I don't because TOTP is less safe than my Security Keys which are already enrolled.
There's a lot to be desired in schools (In the US at least and I assume Canada) but one thing schools do do is bring people from many different backgrounds together for long periods of time.

That in and of itself is educational for the world students will eventually enter. It creates some level of shared experience and social cohesion and underlying social reality. It's not done very well admittedly with a lot of time wasting and poor education and lowest denominator and propaganda flavor of the decade, but the principal still applies.

The thing I'm afraid of with parent and neighbors doing the socializing exclusively is reality bubbles and a fracturing of shared culture.
Then refuse to do it. People complain about the journals, then do free work for a for-profit.
Seems like this whole idea would be easy enough to test. Just compile something like the Linux kernel this way and see if it's actually better.
Yeah. I should have been more clear. I meant as the default. There are all kinds of nice optimizations that can be done with immutable strings compared to mutable ones. Which I probably don't have to tell you, Gustavo :) I have been reading every patch you have made to chez, not understanding half of it but loving every moment.
The internals of App Review’s testing (Twitter thread)
arguing it “emerged from the contentious politics of the 1960s, specifically the civil rights movement and its aftermath

This framing has nothing to do with individual psychology, it’s trying to make a political point.
> And then, once the dust settles, just like after the dotcom bust, you will see a ton of regulations coming down like SOX to “protect” investors when we could have been protected RIGHT NOW, May 2021. It’s utter bullshit.

Absolutely correct. The SEC will make this as another argument for crypto regulations and are waiting for another disaster after this mania ends in tears and lost money designed to 'help' and 'protect' the retail investor.

Then we'll see a 'real' pull back from crypto and a repeat of 2018.

To the late comers buying DOGE from Robinhood, welcome to crypto.
This is the CEO and co-founder of Patreon we're talking about. I highly doubt he cares about his Youtube adsense revenue.

Bitcoin is more international, perhaps? It's certainly easier for many to acquire than a mix of American stocks. Of course, the US is the largest part of the cryptocurrency market and if they thrash about in the pool, it should at least result in some ripples.
Any rationale why he hates unit test ?
Coq is "rooster" in French, keeping with INRIA's tradition of naming programming languages after animals, and pronounced approximately "coke". E.g. "coq au vin" (rooster with wine) is a standard French chicken dish consisting of what it sounds like. Coq (the program) is at least partly named after Thierry and Catarina Coquand, who worked on the Calculus of Constructions (the type theory used in Coq), and maybe also CoC (calculus of constructions, as mentioned).

It gets worse: a standard technique for proving correctness of imperative programs is called Hoare Logic, after C.A.R. Hoare, the inventor of Quicksort. And of course there is an implementation of Hoare logic in Coq.

I was asked a while back to give a talk about this stuff at work. It's maybe a relief that it didn't happen, since I dreaded having to say these names in today's environment. My plan was to put the slides up first (with the names and their origins on them), before saying the names out loud.

I don't think "coq" is slang for penis in French, though my French is at best rudimentary. I'm familiar with "verge" ("rod") and a few similar terms being used that way in French, but the English connotation of Coq's name is coincidental, I think.
There are currently supply chain issues in many different markets that will hopefully mostly resolve by the end of this year.
At least in the US, opportunity costs are likely dwarfed by actual costs in many cases, particularly as you move up the income scale. Despite heavy assortative mating you do usually end up with income disparity between spouses, so you give up less than half of the income for the time(s) that the mother cannot work; when the opportunity cost becomes great enough, then paid child-care starts looking like a win. Lower on the income bracket child-care is often subsidezed.

Then the richer you are, the more it is typical to spend on your kids. I live in an affluent area; my daughter just finished 6th grade and several of her friends are going to middle-schools with tuition in the low $30k range (yes, there is more than one in that price-range in town).
One of the situations I've seen is roughly:
System is up: returns XML or JSON or pretty-format-of-the-week
System is down: It returns a HTML IIS error page.

In the second case, all you might want is to extract the content of the first <h1> tag out of that error page. That's predictable enough of a task that a Regex might be able to handle it, especially if at that point you've already iven up on a full success and you're just salvaging a prettier error message than "system error".
Hi! I've spent the last few weeks developing a visualization of live Bitcoin activity, which shows how new transactions pile up in the mempool before being packaged into blocks.

Whenever I make Bitcoin transactions, I tend to sit mindlessly refreshing a block explorer until they're confirmed. My aim with this project was to come up with something a bit more engaging to watch while waiting for the next block.

The front end is built in Svelte, with the visualization itself rendered in vanilla WebGL. On the back there's an Elixir server which consumes ZeroMQ events emitted by a local Bitcoin node, parses the raw block and transaction data, and forwards it over websockets to any connected clients.

This was my first foray into both Svelte and Elixir/Erlang (coming from a professional background of mostly Vue, Node and Python), so the whole project was a bit of a learning exercise.

Aside from playing with those bits of new tech, I particularly enjoyed the challenge of designing the Mondrian-style online square packing algorithm, and streamlining the graphics pipeline to handle several thousand separately animated squares without hammering the processor or frame rate too hard.

I'd love to hear any feedback or questions!

It's about accessing memory plus an extra conversion step vs. accessing memory in the right order in one step. As an extra, platform-dependent implementations of the accessors could be done, like using the LWL+LWR instruction pair on MIPS.

For reference, check how Linux does it.

Tons of common distributions have infinite support, but the details don't matter for this bit of intuition. If you want to formalize it in a simpler way, just consider it as an arbitrarily large finite number of doors with a uniform distribution.
Yeah it's a little crazy that some 18 year old kid with Robinhood can go 10x long on GameStop but I can't invest in an early seed round startup.
Are you meaning to compare the fallout from 9/11 to cryptocurrency dips?
In fact I just sold my house in SF Bay Area last month for $500k above listing price, all cash no contingencies. We are now renting in hopes that the market cools down but we are worried that this housing mania won’t stop and we will get priced out of the market. But for 500k above list, I couldn’t say no.
Yes! My cello teacher told me “what you can only play slowly, you can eventually play fast; what you can only play wrong, you can’t play at all.”

Keep in mind, this is a man who continued playing as a soloist in concert once after breaking his A string by playing high on his D string. You have to know the rules before you can break them well.
Even if your carrier actually enforces such a policy, the actual implementation is trusted to that part-timer on minimum wage you showed the ID to. They push "OK" on the ID check step, and it's done.

What do you suppose happens when the hot guy in the club who bought them and all their friends a round of drinks says they can make a month's salary in ten minutes if they allow a few of his mates to skip that "annoying" ID check?

And I'm sure that afterwards, once the carrier figures out who was responsible, they'll get fired. But meanwhile your accounts were taken over and leveraged for some scam or (if you own "cool" things like a short Twitter handle or that rare drop in a video game) sold to the highest bidder.
I love this. Pico8's constraints really inspire a lot of creative solutions. I'm surprised they could get Doom running at all.
Haha, kudos for doing exactly what my imagination thinks slightly scifi-esque "autonomous remote farming" looks like! Really neat.

I have some arable land a couple hours away from home so will be following your progress.
I find it a little more intuitive in a visual way with the 100 doors. If the 98 doors that the host subsequently eliminates leaves one in the middle of the pack (e.g. #52), most rational people would look at that door and say "hmm its probably in there rather than in the one i picked, #1"
They only pay out the $100 if the scammers are identified thanks to you, kind of a bullshit offer really.

“People in Japan can now earn $100 for doing the cops work for them.” would be a more accurate headline.
The answer to how is the kernel tested is (historically) mostly manually by a lot of people: https://stackoverflow.com/questions/3177338/how-is-the-linux...

Basically what used to be known as alpha/beta testing. Seems like there's more automated testing these days.

I work on a smaller piece of software with many automated tests that is significantly less reliable. I wonder if there's some lessons there. Another interesting tidbit is that our tests break a lot as well.

In "The Olde Days" many a pieces of complex/reliable software was written without a single unit test or any automated test for that matter. Sure, some of it had bugs, maybe even nasty bugs, but so does most software today. Have we made progress? maybe.
It’s so small because it’s deleting a bad optimization.

No Python on these although I love the TI CAS.
The OPs statement was that more focus needs to be on improving enforcement. I simply pointed out that improving enforcement, by reversing the budget cuts and consequent drop in audit capability within the IRS, was part of the current administration’s policy.

Whether their proposed changes will actually work is another question, but it’s wrong to say there’s no attention there and that the debate is only about raising taxes.

I can’t say I understand the downvotes I received for saying that.
That's fine and dandy... but I've never had an issue with payment processors in Netflix or other subscription services I use. It's nice having it one place but why should Netflix pay 30% to someone who signs up on Apple and then switches to Android? or never uses Netflix on the iPhone other than to signup for the service?

I'm picking on Netflix but the point stands - many companies are able to stand up payment processes. It's not a hard problem and it's not uncommon for companies to have them.

"because apple" isn't a reason to tax a company 30% for things like Netflix that are only tangentally iPhone or when a company can provide a standard level of payment processing.

Apples payment processing isnt THAT good. Definitely not 30% good.
> But "Streusel" is called "strudel" in English

I think you’re confusing two things. Strudel seems to be strudel as well in English, while Streusel is a kind of crumble, it’s not a dish by itself.
It’s really 2 ways to do it, and the defaultdict way (I believe) would have less allocations in a deeply nested loop (since this version has to create a {} and a [] every time).

Also setdefault causes confusion for less experienced users in a way that the defaultdict format does not.
This is my fourth bubble. Bitcoin in 2011 and every one since. It's old hat and quite amusing at this point. I certainly know not to put any money into it I cannot lose.

Do they, though? Even if they know DOGE is a joke, do they have the rest of the knowledge on cryptocurrency to quite understand what they're putting their money into? The risks? The issues of things like time delay and transaction fees which may inhibit pulling funds out quickly? Etc.

The first result on Google for Dogecoin currently auto-completes to "Dogecoin stock". This indicates the degree of ignorance some people are coming into it with.

Large-scale price instability is a general negative. As is lack of wealth among the middle class. For an individual, losing a bunch of wealth on DOGE would just be a silly, or tragic, story. And I tend to agree that fools should be parted from their money...

But if a significant number of ordinary middle class and working class people are vaporizing their savings, that's a social and institutional problem to some degree. It would have ramifications that go beyond those individuals. See when large banks fail. One can wash their hands of it and say they should have chosen a better bank. But you still have mass unemployment and lack of liquidity issues to deal with, from a policymaker's perspective.

And as you say, wealth inequality is a problem. And chances are it's not the 19 year old college student who bought 100,000 of a DOGE a year ago who is cleaning house, on average. Much of this is flowing into investors who have six to eight $ figures locked in DEX exchange contracts raking in fees. For all the democraticizing potential of cryptocurrencies, a lot the wealth is flowing from the gullible to the already-rich.
I don't see how a classical unit test would have catched this, as all other components are mocked away. Regression tests on the other hand can only catch errors that already occurred. I#m not sure that was the case.
It was an analogy. Really going out of your way to create drama where none exists.
There's gcc. Someone ported micropython, but I haven't ever tried it.
COVID freaked out the stock market last year. Then it rebounded due to tech companies bring such a large part of the index. Residential real estate did great dispute COVID in some markets.
I read what you said, I just think you're quite wrong. This (2012) was when they were first having to do damage control for Siri being so awful, and they had the whole series of ads on prime time TV talking about how it was private.

Apple has had privacy and security as a core part of their marketing since forever. They also had a whole set of ads and comments in keynotes about how secure and privacy focused OSX was, taking shots at Windows.
Authors can always privately share their paper.
This is pretty much the gist of the article. People are worried about holding cash right now because they think it’s losing value. We’ve got trillions more about to be injected. All assets are priced high because of it.

If you can get a low interest mortgage right now you’re in a good spot.
>Also there are some IR networking libraries.

They require additional hardware, for IR.

TI-89 does not have an IR interface built in.
Amen.

I'm in the UK which isn't in a hugely different place. I'd quite like to invest my pension fund into residential property run with an ethical approach through a co-op. I was actually laughed at by a financial advisor, who explained that ethics (other than ESG) aren't something he can help with, and that residential property investment is for the big boys - eg, institutional investors.

My bank can invest in property and be morally awful in the process, but I can't do it without losing tax relief on my pension.
Saying that defaults are insecure (which is the case here) is different to the claim there is a backdoor.

A backdoor is a very specific claim that isn't backed up.
Being able to use a controller enables fingerprinting? Producing a laughably restricted browser experience is protection?

"fingerprinting" is one interesting counterpoint to the fact that the browser was highlighted as an alternative to the app store. but that browser is still laughably restricted.

And "because chrome" doesn't change the fact that restricting competition doesn't remove the restrictions put into place largely to force people into an overpriced app store.

lack of competition is a big thing... blocking people from better browsers and not fixing the bad browser in iOS isn't an acceptable answer when the tax for doing so is 30% and a subpar environment.
If you think designer handbags have any relationship to ethics or sustainability, guess again.
The maths is exactly the same, except that the beamforming is at the reception rather than at the emission. But it works based on the same principle.
You accept nastalgy about results of forceful conversion, occupation. It feels awful. I've waited several hours, top comment, tried to write objectively. If anything I've tried to explain how much such "brotherhood" costs, how it is achieved. My bad if it looks like it is against specific state. From my perspective Ukraine occupation is an example of what's happening today. Any nostalgic person may visit it, feel it. People live in fear there.
If anyone is looking for a digital tool to practice Piano I have made a FREE website called Piano Gym!

https://pianogym.com

It's flash cards but for Piano, and works with MIDI Piano connected to your computer.

We use spaced repetition to schedule the flash cards and all you have to do is show up every day and do your reps! The big goal is to remove friction from learning and allow anyone to make their own content if they want to.

I'm hoping in a few weeks to make a show hacker news post, but right now I'm bug fixing and working on getting our curriculum loaded up. Once that's done everything is ready to go! So come check it out if you're looking for a new approach to Piano practice and learning!

And if you're really into this idea, we're on Patreon and appreciate any help making the dream come true!

Did some classical training when younger and I would maybe add one thing about broader strategies of being a musician in general:

Spend up to 1/3 of time with fundamentals (eg scales)

Spend at least 1/3 of time with learning pieces (like this article describes)

Finally spend the rest of the time with just playing and improvising on the piano.
You could try emacs + org-mode + jupyter https://github.com/nnicandro/emacs-jupyter#org-mode-source-b...

It supports moving the current line/region up/down (e.g., using <M-up> in Python mode that is activated for editing jupyter-python cells on <C-c '>).
I think it all depends. I ignore dynamics and fingering when starting out, and I think for the most part, fingering doesn't really matter unless you are trying to play extremely fast sections, which pretty much require repetition to get right.

FWIW, if I was learning Un Sospiro, I would just try get through the whole song. I played it at 1/2 speed and that seemed to be a reasonable attempt.

Sometimes I feel if you have to follow the techniques in the OP, the song may be too challenging for you.
> What I have some trouble getting is the assumption that this has to be managed by a single-vendor platform.

Well the article isn’t saying that the middleware looks after all of your enterprise mapping, it just looks after mapping to/from salesforce.

Salesforce have modularised it, and it is interchangeable - you don’t have to use mulesoft, but it’s another layer in their ecosystem. You want to manually integrate with web APIs? Sure, you have that option.

I don’t get the difference between what you are describing and what mulesoft is in this instance.
The entire world invests in s&p500 and global indices.
Why do you think you would get to keep the fake? The store would want them to take back to their supplier as evidence.
Making a single line is a very bad thing to do in Tetris. You always want to make four lines simultaneously, and there's no easier way to do that than by stacking long pieces.
Absolutely. There is an epic amount of cash floating around which can't be productively invested. So it chases trinkets instead.
Refuse the service to the community that one is embedded in?

I see how one can justify reviewing for certain publishers, e.g. because they publish predatory journals or their shady business practices, but refusing to review any papers would be pretty much freeloading on the scientific community. Sure that's not an option.
Why?

Because it's quite a lot of work to support and provides very limited value over what a graphing calculator app provides especially taking into account the idea that now teachers have to check people's phones somehow.
Those who do not read "Extraordinary Popular Delusions and the Madness of Crowds" by Charles Mackay are doomed to repeat it.
> I'm socially expected to eat, and I'm presented with strange dishes and lots of unwanted attention when I inevitably don't eat.

I'm a very similar way as you wrt food, but not the social pressure part. I don't like eating in professional settings (eating is messy, for one), so I will usually eat alone beforehand and then only order something very small and light (or even just beverages) at the meeting meal. The social pressure thing I find to be easily deflected.

Same goes at bar/drinking events. I don't like drinking alcohol but everyone seems to report perceived pressure to drink alcohol at such things. I haven't found drinking nonalcoholic things to be the big hassle others claim it to be.

I think people build up the expectations more than they actually are in reality. Most other people don't really care that much what you're eating or drinking, if they are eating or drinking what they like.
Intuitively it makes sense it would be half, because there was a 33% chance of winning but now it's 50/50 because 3-1 = 2, but when you read it logically it makes sense.

Yours is the first explanation I 'got', thanks!

Makes sense, although if I think about my personal super market experience, you buy one of two variants: local (grown inside the country borders) or foreign. I assume EU regulation already makes it mandatory to inform consumers of the origins of their product. May be different elsewhere of course.
