2 reasons, I think:

1, I believe Twitter downranks link tweets in the algorithmic feed. If your following is on Twitter, you need to meet them where they are, but you can't meet them with a link. I've seen some people work around this by combining a Twitter thread that summarizes the post with a link at the end of the thread to the actual post, but then you need to write twice (or 1.5x, I guess) the words.

2, thread-tweeting can be lower barrier than blogging. The tech side (hosting a blog and associated yak care) a little, but mostly the writing. Writing a big post all at once is a thing and easy to get discouraged by, where on Twitter, the lack of an edit button forces you to go forward and not second-guess yourself. It's also more ephemeral, less feeling of "this needs to be perfect since it will live on my website forever".

2.5, There's a retro-tech thread tweeter (who I'll avoid naming since they've requested to not be linked from HN due to this recurring complaint) who's said they specifically find it helpful for ADHD since they can tweet out bursts of little updates, work on something else, then come back. Personally I also have ADHD and trying to write a twitter thread is my personal hell, but to each their own :-)
As Elon Musk often says. You have to ask the right question to find the right answers.

If you ask the wrong questions and the optimize to fix the answers to those questions then there is not necessary an improvement.

Car designs is just one aspect of overall road network safety.

And of course even there, the US is also often holding safety back. For example advanced tracking headlights are still illegal for example. And other backwards regulations.
Can you say which books you're talking about, and by which authors? I've also read my fair share of CRT, but mostly papers from the last 10 years rather than books, so I'm curious who you're referencing.
Coupled with a “fountain code” and it’ll be even easier to retrieve the seed phrase.

Fountain code: you take your fixed input block and encode it with the fountain code and it generates an endless stream of output blocks. You only need to pick any N blocks from the stream to decode it.

Using a fountain code means you don’t have to retrieve the output blocks in perfect sequence.
I'm so sorry to hear that. Hope you and the family are ok or as ok as you can be. The numbers are unfathomable and unacceptable.

Very fascinating. Were you at least able to pinpoint a part of the production process that produced different results, or was the difference only visible once the final product was "assembled"?

I referenced only the charge rate. That is, of people who are arrested for certain crimes, how many did Boudin and his team choose to prosecute. This does not include the absolute number of crimes committed. For reference, charge rate for certain crimes like rape went up. He specifically mentioned rape and other crime to media and said he would prosecute these kinds of crimes more, even if the chance of conviction was low. So it wasn't due to a lack of resources. Boudin simply choose to charge certain crimes less, and others more.
It's less of a fingerprint and more of a shibboleth[0].

The benefit of an agency for most companies is that they don't have to keep hiring new freelancers or contractors every few months. They are outsourcing all of that, and the associated overhead, to the agency. Training and managing a team of specialists is not trivial, especially if they are far removed from the focus of the company so nobody really knows how to go about hiring or managing said specialists.
Frugal streaming.

For estimating a median or percentile in a stream, using constant memory.

It's very simple: if the current value is higher than our estimate, then increase our estimate by one. Else decrease by one. It will converge over long enough time.
This is called the Frugal-1U algorithm.

The Frugal-2U is a slightly more advanced version that modifies the step size along the way, plus other optimizations, to converge faster and not oscillate too much.

That didn't happen by accident. It was regulation and threat of enforcement that made hedge funds adopt better practices.

Crypto needs to grow up and accept regulation too if it wants to be taken seriously as an industry.
He just showed that Bitcoin is not mathematically secure.

In fact someone should prove that mathematically secure is a meaningless concept, if your devices are not physically secure.
I have chronic fatigue, but what can go a long way, and what I am doing, is 1. a good diet on the low calorie side of things, 2. a little body-weight strength training each day, 3. do some walking. All of which has the advantage of not taking too much time. But it does require habit building which is tricky.
Wow, this really is pretty amazing (I work in the digital health space and have navigated the absolute chaos associated with wearables integration before). I think that Vital has a lot of potential and can't wait to play with it!

Great term. Occurs to me that a big advantage of good unit tests is you can start muntzing your code until something breaks.
I'm not sure that science as a whole is less useful than it was in 1900, but I'm sure that the average scientist today isn't as useful as Max Planck (but of course he was above average in his own day as well).

This. Roughly a year ago I got interested in efficient immutability for my write-from-scratch-in-C Lisp [0] and started to write a HAMT implementation in C [1], along with a (somewhat hacky, you have been warned) benchmarking suite [2].

The docs are only 70% done (in particular the "putting it all together" part is missing) but it has been a really interesting and enlightening journey so far and can only recommend embarking on this path to everyone.

Ask HN: What tools/services would you use for a data-heavy bootstrapped product?
Specs for this product:

* Will likely store hundreds of millions of rows of financial data of companies

* New data constantly added each day

* Need to aggregate and analyze data to put onto dashboards. Need store results for fast access. Results should be updated whenever need data is added.

* Need to send out email notifications for interesting events after aggregating and analyzing data

This product is bootstrapped - meaning, I have a very low budget.
I unfortunately cannot second this - I went to college with a colleague who went on to work at McKinsey, and who I worked with on a project after he left them.

At this point in his career, 3 years after his PhD, he was unable to do anything except put on cufflinks and produce 120-slide Powerpoint presentations that went 30min overtime like he was working for the DoD.

It was an incredibly saddening sight. I talked to him about this and he was 100% convinced that he was doing his absolute top work by having pointless meeting after pointless meeting talking about nothing at all at great length.

The mindset of charging the maximum number of hours for minimal output is really hard to break out of. You can take the man out of McKinsey, but you can't take McKinsey out of the man.
Journals can still do curation of the stuff that's on preprint archives. Some already do. It's a lot less friction than the current model.
I really love books, but I'm also highly allergic to old ones. Only a few minutes of exposure and my nose will run like a faucet.

Fortunately these days I have my Kindle so I can still collect and read books as I want to.
I always heard the guidance to not put knees beyond toes in the context of kung fu - that it won't hurt you when you are young, but that avoiding it will force you to practice proper stances and gain the correct strength and flexibility when you are young, so that poor technique doesn't become habit and you will remain strong into old age.

I have zero actual science or research behind that guidance - it is just what I was taught. But it does make me wonder if that would be a better way to explain it - not to avoid injury but purely as a marker of proper technique. (And clearly, weight lifting has different markers than kung fu.)
I disagree, the point was to show how object importing scales and he used an extreme example to make the point. He also gives an example of duplicating 10k cubes in Blender (something not out of the ordinary) also sees a massive speed up.

This kind of thing can help understand other bottlenecks in software like Blender as its users and developers get more ambitious as the software grows in capability.

Idealistically wouldn’t one like film makers to be able to work ‘in world’ decoupled from technical limitations?
I have been "reading" Crafting Interpreters for about a year, and implementing variations on what it is teaching. I always try to have one on the go for 10% time or whenever I'm out of original ideas. Got SICP but expect that to take another 3 years at this rate.
The point of a Bloom filter is that it takes constant memory. (The tradeoff is the possibility of false-positives, of course.)

You can have all the reactions available in the drawer, but without "showing why" they are pretty wasted expressions.

I have no idea what that is. A web search did not reveal anything.

> Ignatius Reilly

Not acquainted, sorry.

> feeling seen

No idea what you are trying to say. Who should "feel seen"? In which terms, paranoia? Look: sorry, but I hope you do not consider yourself clear in turn.

> you wear a band t-shirt, you meet people who like the band

Ok, but I do not see how this is relevant to this whole discussion.

> being highly precise and terse

Sure, that is part of the attempt. The burden to interpret, analyze and synthesize etc., remains with the other side. I try to be as precise as possible to facilitate that (meaning: when you analyze something, the "mechanism breaks" if the pieces are "loose", "ill chosen").
This was often my issue. But I remember while learning more Rust I was like: 'now I can go back to my early Rust project to improve it!' and when I did check it: 'oh.. this is actually not bad! How was I able to do it?'
I'll never understand how you can be blind to the fact that most of these "consultancies" can't consult properly because they are hired fresh from uni and never have gotten any real experience and learn on the job. Almost all of them. What's the average number of years a consultant stays in such a company? From my social network I'd say it's around 2-3 years.
I don't understand why people start even a first call without knowing the salary range. As mentioned by others, it's waste of time.
There would be a lot of work to do. The MiSTer project is made for the DE10-Nano, so it is made to work with that FPGA and that set of peripherals. MiSTer, in particular, needs the onboard arm to run support software, so you would have to replace that on this (perhaps with a RISC-V softcore you could build the MiSTer software for but lots of software work to do to make that work).
Any data structure based on skew binary numbers is also fun.
You need to include both the message and the private key in the hash. Since signing the same message twice with the same private key produces the same signature, it doesn't leak any additional information.

I read through the post, is there something about how to make sure this doesn't happen? How to catch yourself falling down that slope?

There doesn't seem to be a way to batch together operations that involve walking through directories and symlinks to do something to a file. This seems to be a major source of complexity.
Potted History: The canning of food
Wow. Another project is doing something similar, but it doesn't have Bluetooth or an OLED display (it uses the same display), so it's not as useful in everyday life, but it's still very impressive work.
one, maybe two? One technical book a month sounds like way too much provided you actually aim to work through the book thoroughly. I recently made my way through SICP because I never finished it when I was studying and that took me like half a year during my free time.
It's intriguing that XFS, which lacks the integrity checks that ZFS or BTRFS offer, is the recommended filesystem for databases, even distributed ones like CochroachDB.

Could you use a WeakMap for this instead?
I had a similar thought when I learned about e-graphs. I'm not sure yet, but I think congruence closure is a slightly different problem from the one Prolog unification solves. In particular, if you tell an e-graph that `f(x) = g(y)`, it will take you at your word -- while Prolog would give a unification error. (An e-graph should also handle `X = f(X)`, while this would fail Prolog's admittedly often-ignored occurs check.)
I don't think the comment you replied to disagreed with that.
Yeah, no. Neither systems thinking nor empathy lead to the position that megacorps should be treated exactly the same way as smaller companies. If anything, the exact opposite is the case.

I was not closely involved with the project. They essentially built the first one to "spec" like "use this kind of steel in the tanks" and the remediation process was essentially tearing those out one by one and "use the steel that we used in the first tank."
Cuckoo filter

"A space-efficient probabilistic data structure that is used to test whether an element is a member of a set, like a Bloom filter does. False positive matches are possible, but false negatives are not – in other words, a query returns either "possibly in set" or "definitely not in set". A cuckoo filter can also delete existing items, which is not supported by Bloom filters. In addition, for applications that store many items and target moderately low false positive rates, cuckoo filters can achieve lower space overhead than space-optimized Bloom filters."

https://en.m.wikipedia.org/wiki/Cuckoo_filter
The point of such an airgapped device is that you can validate its outputs to make sure that it is not using your private key to do shady stuff.

OP's post is that since signatures are not deterministic you have no way to inspect device output and make sure that nothing subvert is going on.

Obviously you should not trust compromised devices, but you cannot know if such a device is compromised.
Most commenters think of this as an honest/dishonest situation on behalf of the agency. A different approach (and the one I'm reading it as) is that 'Isaac' operates as a seller that likes to make 100k per customer or project in any given time.

Not committing to each project, or actually listening, when the customer complains Isaac makes a few adjustments and continues business as usual.

He only cares about that 100k in a few month's time for a project. So now that he got only half of it he probably thinks he did the client a favor.

EDIT: the product is a life-saver for servers, kudos to the developer(s)
A significant flaw of the Pico W is that its idle power draw is too high for battery operation. Rules out a ton of applications that you typically would use a wireless microcontroller like the ESP32 or nRF5x for.
If I put my cynical hat on (who am I kidding, I'm always wearing it), I would ask how useful would it be to prevent Common Knowledge from forming for an autocratic government to stay in power.

Think about the emperor's new clothes, but instead of the kid shouting his message in the town square, the kid privately sent the message to each of the same people. Not the same result, is it?
If this is true, it is beyond fraud. These are crimes against humanity.

My paternal grandfather got diagnosed at around 70, and my father is 62 now, definitely getting more forgetful but normal for 60+... Still, I worry about him regularly. My father is a clinical psychologist, he's helped people all his life.

These news make me so angry I can hardly see straight. I genuinely hope this sociopath waste of skin gets Alzheimers himself, and has to relive every moment of his disgusting crimes as his brain slowly turns to mush and he forgets every person he ever loved(if he is even capable of love...)

It's the age-old battle between investors and entrepreneurs wanting to make crazy money and creative people just trying to make enough to live somewhat comfortably.

It's also happened in the brick and mortar world, when American ideas took over Europe.

Could you elaborate? Seems like there’s a bunch of things that can’t be batched together on an ordinary file, without involving symlinks.
It depends on what I need. If the company gets into some new technology then I read a couple of books on the topic. I try to get generalist books instead of framework x.yy books.

Is every human a net-positive to society? Obviously an objective measure is impossible to establish, but I doubt everyone is a net-gain.

How random are car-related deaths? Is this actually a problem?
As for #2. I'm _really_ jealous for people who can use Twitter as a kind of a blog platform. It's effectively write-only and you can't go and edit things afterwards.

My jumbled up mess of a brain would never allow me to get a coherent 20+ tweet chain out without typing it out first, splitting it to tweet sized chunks, editing, re-editing and then copy&pasting it to a thread manually.
Maybe this is already the best we can hope for? Soon it will be a choice between overlayed captions on Tiktok-Videos, or zero eyeballs.
> Much better advice is found in The Practice of Programming: almost all programs can be written without any data structures but arrays, hash tables, linked lists, and, for things like parsing, symbolic algebra, or filesystems, trees. So just use those if you can.

In general, as much as possible use stuff you already have good libraries for.

Often, you can get away with much simpler data structures with a bit of clever pre-sorting (or sometimes: random shuffling). Relatedly, batching your operations can also often make your data structure needs simpler.
The assumption that the "European" solutions would be the true Paladin of the justice is historically/morally wrong. It cannot be serious and as we can see in this blog post, is just fed by companies fighting for the same market.
This is clearly stated on Apple's EU product pages.

Germany (VAT rate 19%): https://www.apple.com/de/shop/buy-mac/macbook-pro

1.599,00 €

Einschließlich MwSt. und ges. Gebühren i. H. v. ca. 266,00 €.*

Ireland (VAT rate 23%): https://www.apple.com/ie/shop/buy-mac/macbook-pro

€1,629.00

Total Payments for your device include VAT of approx. €305.00.*

From the US store you need to go to the checkout page before you see the tax payable, so assuming San Francisco (sales tax rate 8.625%):

Subtotal $1,299.00

Estimated tax $112.04

CA recycling fee $4.00

Total $1,415.04

Sales tax is lower in the US than VAT is in the EU. Taxes are the price you pay for living in more a civilized society.
From reading online it feels that most important thing is to be first. And prevent anyone else even from potentially moving forward on your topic. The actual scientific progress is secondary.
