We recently did a proof of concept with P for our system, and the reception was warm enough that I expect adoption within the year. I wouldn’t exactly call us obscure, at least in the sense used above—greenfield big data system with a bog-standard mix of AWS services.

I will say that time to productivity with P is low, and, in my experience, it emphasizes practical applicability more so than traditional modeling languages like TLA+ (this point is perhaps somewhat unsubstantiated, but the specific tooling we used is still internal). That is to say, it is fairly easy to sell to management, and I can see momentum already starting to pick up internally. No Ph.D. in formal methods required.

And re: the hiring bar, I agree that the bulk of the distribution lies a bit further left than one would hope/imagine, but there is a long tail, and it only takes a handful of engineers to spearhead a project like this. For maintainability, we are betting on the approachable learning curve, but time will tell.

Studio Ponoc had Miyazaki's blessing. I doubt the same can be said for OpenAI. OpenAI doing this without even asking might not be illegal, but it comes across like an act of incredible disrespect for the very creators that these memes are masquerading as an homage to.

“When we opened the new studio, Studio Ponoc, I went to report this to Mr. Miyazaki,” he went on, “and he gave his blessing and said, ‘You really need to have the conviction to go create a new film studio and the conviction to show children worthwhile films. And every film you make, you’ll have to realize that has to be a film that is worthy to show to children’.[1]

Just launched my very first app 24h ago — Neuron AI, a fully on-device private AI assistant.

No cloud. No tracking. No data ever leaves your phone.

It’s fast, offline, and designed for 100% privacy and control.

You can instantly transcribe and summarize any audio — from meetings, lectures, voice notes — and chat with your chosen LLM without worrying about anyone else reading your data or it being used for training.

Turn on airplane mode and it still works. That’s how local it is.

So far: 61 active users and $157 in revenue — would love your feedback! You can download it for free! If you want to learn more, here's the website: https://neuron.unumlabs.ai

Switched from notes to Microsofts cloud thing and Lync, notes was better. We also had hundreds of not thousands of small apps in notes. Supposedly Microsofts solution was going to be much cheaper if everyone got off notes, but we were given to time, budget, framework or even guidance when it came to the apps. Several years later they still paid a lot for notes.

I've been working on a documentation system that improves how AI assistants understand project context. The problem I'm solving is that traditional documentation approaches are too fragmented for AI to effectively process.

After struggling with vague outputs from AI coding assistants, I started experimenting with MECE principles (Mutually Exclusive, Collectively Exhaustive) to organize technical documentation hierarchically. Think of it as creating a "mental model" for AI rather than just reference docs.

Some early results: - 40% reduction in back-and-forth iterations with AI assistants - Much more consistent code style and architectural patterns - Better preservation of domain knowledge across the project

Currently refining the metadata structure and creating templates for different project types. The system works especially well with Cursor AI and similar assistants that can process structured context.

If anyone else is exploring this space of "AI-optimized documentation," I'd love to exchange notes.

> you are never graded on whether you did your best and honestly report what you observe. From grade school on, you are graded on whether or not the grading authority likes the results you got. You might hope that there comes some point in your career where that stops being the case, but as near as I can tell, it literally never does. Right on up to professorships, this is how science really works.

This, so much this. I disliked any lab work in my science classes (in HS/College) for this exact reason. I can't tell you how many numbers I fudged because I wasn't getting the "right" results and there was no time/appetite/interest in figuring out why it was wrong, my options were lie and get a good grade or report what I saw and get a bad grade.

And yes, in college specifically, the equipment we were working was rough. There was so much of "let's ask the other 2 groups near us and we will all shave our numbers a bit to match/make sense".

Thanks!

> Split Spanish between Spain and Latin America Will do!

> Add difficulty levels (consider speaking speed and vocabulary used)

I'm working on splitting it up in easy/normal videos. That should be do-able to assess.

> Ability to select which topics I want the videos to be about (e.g. science, celebrity gossip, AI)

I'm thinking about creating a browser plugin where you can tick a box to automatically import it into Fluentsubs. Or create an exercise from an existing video. It will take minutes before it is fully transcribed but it can be a nice way to prep your own content without people blaming me that I serve biased content.

I'm not sure though if people are willing to install browser plugins. I'm always a bit weiry with plugins that are invasive on websites like YouTube.

The Congress providing mere veneer of a republic isn't convincing. It's called Principate, and it's dictatorship.

A republic is an empire of laws, not men.

This executive is insisting he doesn't have to follow laws he doesn't personally like. A retroactive veto. It's contrary to the oath of office, and the duty to uphold the law. It's stated in the text.

This Congress is already merely decoration, serving an emperor, not their state's interests.

We have many examples of dictatorships with functioning courts.

Indeed, it is very easy to forget the struggle when one has sacrificed nothing to achieve it.

At least WWII, unlike those preceding it, has a vast well of literature to draw those lessons from. The trouble, however, is not just getting younger people to sit, read and analyze it, but also to separate the wheat from the chaff, so to speak, with all the propaganda and misinformation to be had these days about the events of WWII, the Holocaust, Hiroshima/Nagasaki and so many other things that would make this list exceptionally long.

Books, are not the same as having lived it, of course. Aleksandr Solzhenitsyn put it best in The Gulag Archipelago.

“If it were possible for any nation to fathom another people's bitter experience through a book, how much easier its future fate would become and how many calamities and mistakes it could avoid. But it is very difficult. There always is this fallacious belief: 'It would not be the same here; here such things are impossible.'

Alas, all the evil of the twentieth century is possible everywhere on earth.”

love it. but that makes me think that development is no longer the bottleneck —distribution and positioning are. and my bet that the ASim fucntionality will find it place in the current media platfrom.

say, if tiktok launches an ai app store, it won’t be for complex software—it’ll start with low-friction, high-retention apps: ai-powered video enhancements (think face-swaps, lip sync, object replacement) or micro-utilities, something like ASim does.

for platforms, it’s obvious—more engagement, higher monetization, and a new vertical.

for creators, it’s a no-brainer—why funnel traffic to some app store when you can keep users inside tiktok, get them to install, and even monetize directly?

even the infamous 30% app store cut could be creatively sidestepped—imagine launching your own meme coin for in-app purchases instead.
Show HN: Zig Topological Sort Library for Parallel Processing
by ww520 | 2025-04-01 17:48:45+00:00
I believe the best way to learn a language is by doing an in-depth project. This is my first Zig project intended for learning the ropes on publishing a Zig package. It turns out to be quite solid and performant. It might be a bit over-engineered.

This little library is packed with the following features:

- Building dependency graph from dependency data. - Performing topological sort on the dependency graph. - Generating dependence-free subsets for parallel processing. - Cycle detection and cycle reporting.

I'm actually using a 1600W PSU. 1400W is my target max draw. This is a dual EPYC (64 core CPU each) system btw. The max draw by the CPU+MB+Drives running at peak 3700MHz without the GPU is 495W! Adding 4x 4090 (underclocked) will quickly get you to 1400W+.

I'm working on the multiplication circuit in the Pentium; I've done a partial writeup: https://www.righto.com/2025/03/pentium-multiplier-adder-reve... The short answer is that multiplication uses a large tree of adders so it can add up all the long-division terms at once. It also uses base-8 for the multiplier to reduce the number of terms. The adders are 4:2 carry-save compressors that take four numbers as inputs and produce two numbers as outputs.

I also wrote about the Pentium's division circuitry and the infamous FDIV bug: https://www.righto.com/2024/12/this-die-photo-of-pentium-sho... The short answer is that the Pentium used base-4 SRT division, similar to long division but generating two bits of result per cycle. It used a lookup table to determine the two quotient bits; an error in this table resulted in the bug.

Awareness and appreciation of the utility of humor increases with age and/or maturity.

Ms. Super-serious "I'm in university now and no longer find fart jokes funny" is liable to enjoy them again in her golden years.

There's no surer way to project a lack of self-assuredness than to be the stiff incapable of chuckling at a harmless prank.

F# is a wonderful language, one that I write as my daily for the second time during my carrier. It _baffles_ me how it isn't more popular than it is because it truly is very very good. And I say this as an experienced and avid functional programmer.

We even do the frontend in it using Fable and Elmish, which is to say: we basically write our frontends in Elm, but the platform is .NET.

While reading AI Engineering[1], I was inspired to take a crack at an idea I've had for a while - diffusion-based LLM. The accessibility of shakespeare.txt[2] and the proliferation of tinyGPT implementations has made vibe-coding LLM research on the brink of possibility. It does help to have a familiarity in the datascience/ML/AI space in order to check and guide appropriately, but it's amazing how well the virtuous cycle is beginning to work.

Apparently everyone gets them but the burden (% of beats being screwed up) is important. A high burden for prolonged periods means damage accumulation.

I had 2 24 hour monitors and one caught 700 eptopic beats in a day. Another couple months later, 15.000 in a day. The second one was a concern for the cardiologist. She ordered a couple more tests, started beta blockers asked for diet changes.

I still have a high burden as I can feel them but whatever..

The question is, what evidence is there that the most simple structures we can call brains are doing something which is fundamentally impossible to do with something other than a brain.

Given that brains are fundamentally governed by the same physical laws as everything else, there shouldn't be anything about them which cannot be replicated in some way by something sufficiently capable of emulation of their processes.

That's not to say it's simple. Just that brains obey the laws of physics, and as long as that's true, they should be able to be replicable.

Unless your contention is that brains are somehow able to operate outside the constraints of the laws of physics, in which case we're going to have a fundamental difference of opinion as to the nature of the universe and whether things with brains are particularly special.

Wow for SDR, 0.75xMRR for each demo? So if your typical MRR is $1000, you'd pay $750 per demo?

My wife used to be SDR and I seem to remember she got paid much less, maybe like 0.1xMRR.

Obviously your economics work & scale, just curious to understand how - is your close rate really high?

If an AE closes an annual deal (worth $12k in this hypothetical), and there were 4 other demos that didn't close, then you are paying $2000 to AE and $3,750 to SDRs, or almost half of your revenue on comp.

This is how I remember my own undergrad physics and chemistry labs: Terrible equipment and no time. The students who turned in faked but plausible data that looked like what the professor expected to see would get A's and the students who actually did the experiments and reported the crap they measured got lower grades. Everyone just learned the wrong lesson: Figure out what the data should look like and fake it.

Construction projects get reasonably accurately estimated every day. Probably because:

1. People have been doing it long enough that estimator is a job description.

2. That it is a job description, means money is spent on estimation.

3. Money is spent on estimation because getting it wrong can cost money.

I think the problem with software estimation is that there is usually no culture of estimation, usually very little direct incentive to get it right, and no regime of formal training for those responsible.

To put it another way, software does not have standard documents for estimating.

Saying "you don't have a right to pass on your property to your family" is the opposite of high trust. I'll grant that the moral answer beyond a certain point is to limit your children's inheritance to what will give them a comfortable life, and then engage in philanthropy a la people like Andrew Carnegie.

But claiming the government has to force people into this is low-trust to the extreme. It's saying "we're going to take these things we already taxed you on, because you can't be trusted to use them responsibly and we can."

You can't regulate your way into everything. Good government can only exist alongside the unwritten rules that made people like Carnegie decide that the right answer was to give their wealth away to the public.

This is true of most of the SF Bay Area on a 100 year timescale too. I grew up in a house on land that was formerly a cherry orchard. Some of the most ideal farm land in world has been converted to residential neighborhoods and is far too expensive to use as farmland, well, except for Walter Cottle Lester.

I had a physics class in my high school. 2014? 2015? Around then.

The teacher had us using a stopwatch on our phones. We would repeat the experiment several times and average the result, because manually doing a stopwatch was terrible- multiple samples kinda helped.

My group figured out we could get things way more accurate if we videoed the experiment in slow-motion with a phone, keeping a digital stopwatch in frame. It took an extra step of math, subtracting out the start time, but in slow motion we could be accurate to 1/120th of a second. Our results were easily the most precise in the class. Equipment can make a huge difference, and slow motion video was considerably more accurate than “Mike trying to time it right”

I was in honors freshman chemistry at university. Tough class, all homework (lots of it) graded rigorously, but only the midterm and final counted toward the course grade. So if you wanted an A you had to get an A on both exams.

After midterm, during every other lecture at least, the professor would sound a refrain: “An orbital is not a house! An electron does not live in a house!”

Final exam had a small number of complex problems to work out with pen and paper, tough stuff, lots of calculus. But the last question ended with “where does the electron live?”

That final problem, if you ignored the end wording, was super easy, something almost trivial to do with Helium iirc. The class had about 25 students in it; about 5 of us independently had the same thought: “this is a trick question, ‘the orbital is not a house in which the electron lives!’” And, independently, that’s how we five answered.

And we got marked wrong, all our course grades dropped to B+/- because of that one damn question.

Over a lunch or whatever, we discovered our shared experience and approached the professor as a group. He listened patiently and said: “Ah, right, I did insist on that idea, it’s understandable why you would think it’s a trick question and answer that way. But I still consider your answers wrong, grades stay as they are.” Some in the group even went to the dean and, to my understanding, he said it’s best to consider it a life lesson and move on.

Thank you for all the kind responses.

I also want to make a similar article, where I calculate an ECG for the simulation, and then make and explain the changes necessary to make the ECG look realistic. A main challenge will be that the depolarization has to happen very fast relative to the repolarization, which may be computationally difficult for a cell-based simulation.

> Most of these VPN services are also trying to get you to do DNS with their DNS servers. Again, a major potential privacy leak problem.

The privacy problem is most people using Google's DNS servers in the first place. A VPN is unlikely to keep your browsing history out of Google's hands when you're sending them a record of every domain you visit, when, and how often.

A VPN service is basically saying "Trust us more than you trust Google/your ISP" and that by necessity means giving them your DNS traffic as well.

> I'd have an inherent mistrust in one that has both a cheap fee and the seemingly endless budget to advertise everywhere on youtube. They are getting money from somewhere and I doubt it's from grandmas signing up for the service.

They make a lot of their money from file sharers (some of which are also grandmas). The VPN will keep your ISP off your back and the MPA/RIAA at bay. I assume most VPNs like that are being monitored (if not outright operated) by the NSA or some other three letter agency. It's fine if you're just using the VPN for regular browsing or to torrent TV shows though because they're not going to spoil their honeypot over something so trivial and the VPN's success at keeping pirates safe builds their reputation as a secure service.

> The average Amazon engineer is not expected to have awareness of CS fundamentals that go beyond LeetCode-y challenges

I find this a bit unsettling. There are dozens of great CS schools in the US. Even non-elite BSc programs in EU sometimes teach formal methods.

There are also some good introductory books now, e.g. [1]. Perhaps its time to interview more on concepts and less on algorithmic tricks favored by LeetCode?

I doubt current undergrads can't go beyond LeetCode-like challenges.
