I've been playing piano/keyboards for 35 years. I definitely don't play at a "professional" level, but I gig locally, and can play pretty well by ear, and in an ensemble. I'm not an amazing player, but I have enough experience to know something about what you're talking about.

What you're asking about is impossible. Not just difficult. You might be able to learn something about moving your fingers independently with rhythm on a computer keyboard. But at about the time you get to one week of experience, you'll probably be doing at least as much harm as good in terms of learning to play piano music on a computer keyboard. It is too different.

Partial list of problems:

Size of keys
Position of keys
Number of keys
Travel distance of keys
Velocity sensitivity of keys
Sufficiently low latency of audio output (can be solved with pro audio hardware)

To give one quick example of a deal-breaker, on a piano, you can comfortably, and in a neutral hand position, put your thumb and four fingers on 5 consecutive white keys. The layout of a computer keyboard doesn't allow for this at all.
I think a lot of people living at that time would constitute 2% of the current Asian population having had him (or her) as an ancestor.
I am a huge fan of this type of incremental generative approach. Language isn’t precise enough to describe a final product, so generating intermediate steps is very powerful.

I’d also like to see this in music generation. Tools like Suno are cool but I would much rather have something that generates MIDIs and instrument configurations instead.

Maybe this is a good lesson for generative tools. It’s possible to generate something that’s a good starting point. But what people actually want is long tail, so including the capability of precision modification is the difference between a canned demo and a powerful tool.

The examples are quite nice but I have no idea how reproducible they are.
zig compiler does lots of things for speed that would push it well into unsafe rust, or unchecked rust (like using u32 index tags in arrays instead of pointers)
Latin America is very big, I don’t think you can generalise your experience to a whole subcontinent.
I think you've got causality twisted here. People prefer having a job, the higher paying the better. High paying jobs exist mostly in metro areas, so folks move there for work. Preference for the suburbs is just folks exercising their perfectly natural tendency to want as much space/land/house as they can afford while maintaining access to services and proximity to work. I'm quite confident the majority of suburbanites would strongly prefer living on 20 acres if they could still get to work in 20 minutes and the grocery store in 10.
More like it is surrendering on the right to speech, something we need to regulate large tech platforms into respecting in general (like the common carriers and utilities they are). I don’t trust Zuck’s motivation for making this change now, but it is still a very positive change after the long history of censorship and inaccurate/misleading fact checks on Meta owned platforms.
It is interesting that the FDE has a lower salary band than the staff software engineer. Is that role base + commission?
> Device drivers are a huge obstacle for any fledgling OS.

I've wondered if new/hobby OSes would fare better by starting out targeting a popular single board computer like a raspberry pi? A mostly fixed set of hardware to make/get drivers for and test your system on.

>but in most cases that's not going to be believed by a jury.

Is there are least some argument of reasonability? I have an old Runescape account I would love to be able to get back into, but I don't even remember the email it was tied to, much less the password. I was a kid back then so even the card that paid for membership was my parents. Is there some expectation that the prosecutor has to show the account was accessed in the last X years, or is this effectively a backdoor to keep someone in prison indefinitely?
Easier than Elite.
Let me present you with a use case: let's say that the New York Times (55.2 million followers on Twitter) decides to leave Musk's land and that they will fully embrace decentralized social media. Let's pretend that they learned their lesson and that they swore to never rely on someone else's platform to broadcast their own information, so they are looking to do anything they need to own the infra needed to publish all their content and reach anyone who wants to access them.

In our scenario, they don't care where their 55M followers are hosted, but they do care about giving accounts to their ~5k employees and they want to be able to follow any of the newsworthy people and institutions: politicians, entertainment celebrities, athletes, etc.

What would be the requirements and associated costs for the NYT to provide this, and how do these costs change if/when more institutions decide to follow suit?
I know it really doesn't count for much but I suffer from hyper-mobility and have ADHD as well. So hey we have an n of one so far.
It seems like they're entirely different units?

TOPS means Tera Operations Per Second.

Petaflops means Peta Floating Point Operations Per Second.

... which, at least to my uneducated mind here, doesn't sound comparable.

Uhhh... it's fine. I have never once thought to myself: Gosh, I wish those Mozilla folks would overhaul the address bar...

had a bounty. the RSA challenge unexpectly finished in 2007, task is left to the reader to speculate what happened in 2007.
Cool!

A large part of the reason I'm using these other services instead of hosting my own is because of mobile apps + browser extensions.
I think you are confusing "trivializing" with "highlighting".
So fun, feeling inspired for 2025!
Well, in typical use cases RSA usage is very limited (eg some operations during TLS handshake), so the 40-100% boost wouldn’t be across the board, but likely shave some milliseconds per connection.
Loosely related, my HiSense TV has a wifi remote that apparently sends separate key up and down events to the TV. If the wifi happens to go down while you're holding the volume up button, it never sees the "key up" so will just hold whatever button indefinitely, including the volume button, which is how I discovered it.
Last time I asked a question, I put "Thank you for any help, it's much appreciated." A drive by moderator, who did nothing to help me improve the technical content or clarity of the question, edited and removed this. I asked him politely to not change my own words, as it's custom in my culture to thank people. Big in-charge moderator on a power trip's most important mission that day was to inform me that he's in charge, and denied the request.

This is incredibly toxic and stupid, contributes nothing, and as such, it's not worth providing your expertise for free. The site years ago was an amazing resource of like minded people helping each other. The only cure would be to stop community moderation and do professional only, as well as guide the noobs to resources like chatgpt first for "how to I write a hello world", while sorting the quality questions onto the front page.
> what is the alternative exactly?

created by putting in work of equal value, you know, like that one form of money that has lasted for millenia, as opposed to these fiat tokens that always fail.

> like no duh the economy & money system was created out of thin air. we created all this shit out of thin air.

One side of the economy was created out of thin air - the money. The other half - goods and services - were created through work. Sound like a fair system? Or a con trick?

Keep working for the tokens dude, and the banks will keep creating them out of thin air until you realise what they're doing.
> If there was any manipulation of community notes in the last 2 days, how would we know?

You can't know until the data is published. 2 days isn't that long though. Just wait a couple more days for the next data dump, then run the algorithm and compare the results to what the X UI was showing at that time.

> If there’s manipulation of this data before it is published, such as ratings or notes never hitting these data files, how would we know?

That would be a bit more sneaky than just outright removing notes. As you noted, you'd need a user whose ratings or notes were omitted from the dump to notice and come forward. Or perhaps with careful analysis you could prove that the manipulated data could not have resulted in the allegedly removed note being shown and then later not shown, indicating something fishy happened.

Theoretically if X wanted to improve on this system, they could go even further and implement something like certificate transparency (append-only log verified by a publicly distributed merkle tree), or create an independent third party organization that users interact with to submit and rate notes, rather than that happening through X's UI. Given the threat model though, I feel like the UX and complexity trade-offs of that wouldn't be worth it. Open sourcing the data and algorithm as X has is already far more transparency than we get from any competing social media company.
No one, and let me repeat that, no one "gets" linear algebra, differential equations, or frequency domain on the first pass. It takes years to absorb and multiple passes.

See:

Bruner / Spiral Curriculum.

Ebbinghaus / Spacing effect

Hattie / Deep-surface-transfer learning

Chunking ("How People Learn" has a good copy on this)

Etc.

The way you do this is you take a course, and then you take more courses. After a few years, it all connects and makes sense. The first course, I find, is often best short, simplified, and applied. Once you get through that, you can go deeper.

Different angles are nice too. For linear algebra:

- Quantum computing

- Statistics and probability

- Machine learning

- Control theory

- Image processing

- Abstract algebra / groups / etc.

- Computer graphics

All come to mind.

On a mile-high level, this course seems ideal for a first pass. On a detailed level, I'm confused by some licensing issues.
I'm thinking about the motorcycle motor. If they're really lighter than competing motors, I don't see the downside of using them like a traditional motor, taking the weight savings, putting it inside a sealed cavity, and coupling it to a driveshaft. Simplifies some of the other problems with sealing and bearings mentioned elsewhere, avoids unsprung mass.

Meat contains only insignificant amounts of carbs. The human body can convert protein to carbs (glucose specifically) but the rate at which it can do it is limited, and my guess is that if it can't burn glucose, a metabolically-healthy body will burn fat (rather than glucose made from protein) until the diet has been quite deficient in calories for at least 3 days.
Reading the articles below it appears that BMI should be sub-categorized by race and gender categories - healthy weights for [X-race + Y-gender] person to increase its efficacy as a health tool.
First time a 512-bits RSA number (RSA-155) was factored was in 1999!
What it's like creating a simple free website in 2025
Yeah, it's always odd how "the number of raves happening in the world" seems tied to "how connected am I to a group of people who want to push the boundaries of a party".

Sometimes raves are happening every 3 days locally to me, sometimes the world has stopped all together. Very odd and polite that the world can tell when I am not interested in that level of (to be clear, often enjoyable) debauchery.

I presume that they will start up again once I get my warehouse finished on my off-grid property in the desert...
In general, in such situations the senior devs pull the ejection cable, and form a new company without the managerial labor cost overhead.

If they still want product support, than get a quote from SAP first. Ghost ships don't need managers by the way...

Almost every sick division I saw had a 15% budget kickback clause in their contract for unspent resources. =3
None of that really makes money for a hospital. Most of what hospitals do is direct, hands-on patient care. Software improvements can at best deliver some small cost savings or slight reductions in clinical errors. And many hospitals are non-profit or government run, so there's not even a direct management incentive to improve financial performance.

Do you know what makes money for a hospital? Buying a new MRI machine. They can directly charge customers for scans. In budget planning cycles any proposed IT upgrades have to compete against stuff like that.
One can easily see how high real estate prices can translate to all those being more expensive.

Colleges pay rent. Colleges pay salaries to people who pay rent. All those go up with high real estate prices. Further, even if the college owns a land, the money they earn on that land has to compete with what a developer who is willing to tear it down and put up a residential building which now earns higher rent or sale price.

I don’t think all the increase comes down to high real estate costs but it’s clear that high real estate costs can easily raise prices downstream across nearly every area.
Intel 8052AH-BASIC. I loved the manual for that chip! Written with a sense of irreverence that was very unlike Intel.
I've also argued in favor of that; I don't actually like Pis personally, but they're a super common, cheap enough, easy to acquire system and that's huge.
> One thing I would say though is that stating a certain pronunciation is "correct" never sits well with me.

Who cares how it sits with you? There is a "correct" way in every aspect of language - accent, spelling, etc.

> Language is incredibly fluid, and typically when a certain pronunciation is deemed 'correct' it's related to people in power and how they pronounce(d) it.

Probably. But somebody has to set the standard.

> There are of course regional variation where claiming one is more 'correct' than the other doesn't hold up well (north USA vs south USA),

Bad example. There is most definitely a "correct" american pronunciation. It's why much of news/media has a neutral american accent. Most americans, from whatever region, can speak it to some degree or another.

> but even further I'm sure most would take offense at the idea that everyone in the US mispronounces words where they differ from British pronunciation.

Who would take offense? Not me. Not anybody I know. Especially since american english is the dominant form of english and probably will be the standard around the world.

> but you get my point).

You have no point. Just misinformed silly gripes. All languages standardize in some form or another whether it be accents, pronunciation, spelling, script, etc.
> Given the choice of equal pay, most people would pick a cheap suburban 2000sqft house with a garden for 10% the price of a SF condo.

This already happened during Covid, and no country substantially de-urbanized. In fact, urban real estate prices skyrocketed.

The only cities where prices stayed flat or went down were highly over-priced places that people hated living anyway (like the Bay Area).

A lot of private funding at these consultancies actually comes from pet features. Some company says "hmm, we sure do rely on XYZ feature a lot, would be nice if it were faster", they throw some money at a consultancy like Igalia, and then it becomes faster for everyone. No need for a big pot all at once, though I'm sure that'd be really nice.
I agree it's not specific to MS. But MS was probably inducing much more demand and thereby making them eat more fees than they planned to. (I don't have any inside information though.) Adding a premium would make it a little less attractive to MSers.
I do think that for good faith arguments the Internet has been very successful in removing unintentional falsehoods -- there's a lot less of the "Eskimos have 100 words for snow" nonsense than there used to be because people can easily check that that's a myth rather than just repeating something they once heard. But obviously things are different when people are trying to promote a falsehood even (or even especially) one they know to be false.
>You have to have carbs for your brain to run.

The brain can run well on ketone bodies (which the liver makes from fatty acids). In fact, causing the brain to run on ketone bodies is used by doctors to treat illness (and not just epilepsy).

The rise and fall of "fact-checking"
I actually really think that starting with assembly would be a great place for someone to start learning programming. But not x86 and not on a traditional PC. Instead using some microcontroller attached to a breadboard with a few simple peripherals like a keypad, simple LCD (or maybe an 8-segment).

The control-flow is obvious, the syntax is simple enough that novices shouldn't struggle with it, and writing directly to pins to control the peripherals gives immediate concrete feedback.
This is functionally identical to the capacitive approach. Pressing the button charges the cap whose voltage decays when released (starts the timer). If the button is pressed before it decays below the "release" threshold (timer expires), the cap is recharged (timer restarted).
If that’s the argument, don’t you think we would never be able to find greatly rated apps in App Store or videos on YouTube, right ? Am I missing something ?

If someone reaches out to me unless they have a very unique skillset - no “full stack developer” and “I got my last job because I can invert a btree on the white board” are not special skill sets.

I’m going to refer them to the ATS.
I have often watched aluminium casting processes that have a lot of oxidised metal accumulating on the surface and that makes me wonder if they have ever used an Argon or Nitrogen as a blanket because this dross often gets dragged into castings = defects, many of which are hidden? Does Tesla blanket their system with inert gasses? One can even think a whole room could be blanketed, if it was remote operated - or the staff wore air supplies? It would take an assessment to create the minimalist inert system with air, and a remote system = no air needed??
Founder here, thank you for this note we will build a jig to test this out and share results on our docs. One of the things we have done to reduce wear over time is that the spring contact is on the device and we expose a very small contact surface from the housing. Check this - https://ibb.co/xqm3z3W
Neat! I remember contributing the expression parser code for the Knoll et. al 2009 work that you cited in your SIGGRAPH paper. That just rewrote a single user-friendly expression into nested function calls to our IA library in GLSL, without any sort of optimization.

You've clearly taken things waaay farther. Nicely done.
lower value, lower tax. lower value, lower rent.
It’s more of an arts and community festival than a music event. There’s a smattering of respected DJs/producers each year and some good sets, but otherwise there’s a bunch of art cars roaming around thumping generic party music. Absolutely nothing against Donna summers, but I’m not shitting you when I say I heard her around a half a dozen times the first big party night, for instance. There is no curation there like a music festival.

That said, absolutely worth going to at least once, for everything else.

Oh, I wasn't aware of the end of the challenge. But 1024 was definitely not broken by then, at least not by brute force.
Stuffing bytes through a faux serial port with rate limiting, or mangling the result into text? Those actually bother me less; they're kinda ugly, but in my mind they don't compare to cutting through all the nice abstractions and shoving raw bytes down a hardware port on a running Linux system.
Sometimes instead of a complete dump, you might mutually agree on a third party forensic lab to analyze your phone and only provide relevant details to the opposing side. Usually there's a few rounds of review where you can remove some details/records that are not relevant before the distilled records are sent to the opposing counsel.

I'm as anti-RTO as anyone, but I've seen this asserted over and over but have never seen anyone give evidence in favor. As I understand it the claim is something about cities giving tax breaks to companies for having offices? Or is the idea that CEOs have investments in real estate?

Does anyone have a source that actually shows that this was a factor?
Would be nice to have more of a control with non coffee drinkers.
I graduated college in 1987 (when the letter was first published.) I was probably the last generation to bring a typewriter. My freshman year I typed term papers on an old Smith-Corona. By my senior year, I was writing on a Commodore64 and printing on a dot-matrix printer (at the computer lab.) I also bought my first computer (Amiga 500!) that same year. This letter hasn't aged well obviously, but it wasn't a completely unreasonable position at that very brief point in time. Reminds me of the 1998 Paul Krugman quote https://quoteinvestigator.com/2023/10/26/internet-fax/ about how the internet will be as impactful as the fax machine.
I dreaded videos for a few reasons, some of which could have been fixed, but some were human nature.

First, they didn't play in all browsers at the company I worked at. That meant I had to either download it, or use a different browser for that.

But even then, it was a game "guess what the CSR thought was wrong" in the video. Usually after watching a rather long intro sequence before getting to the actual bug.

If the company is trying to replace written bug reports with videos for speed or convenience, it's a nightmare for the devs.

If it's just an add-on to show the specifics, then it might actually be good. I rarely got those.
You know, not everyone tries to profit from everything all the time.
Yeah big cities provide a one stop mall like experience for 'experiences and culture' for people who need that curated for them. To me it's the most boring, non-organic, empty experience, but I've always preferred non-mainstream scenes or to hunt out my own entertainment/style/beauty. I can see the draw for people that doesn't work for though.

It's funny that cities various 'interesting districts' are normally just suburbs that the city absorbed. But yeah, suburbs are just awful places without their own culture or interest (unless absorbed, then they are a distinct interesting district).
I was enjoying this, but then reached a point where the speaker said

> BMI is just nonsense, and not only that, it’s almost certainly racist nonsense […] it has been shown to be healthier in the group they call overweight than the group they call normal

Which makes me doubt the veracity of other claims made, to say the least
