The irony the deck presents 3 very different presenters to show that you don't need to be Tony Robbins to be passionate.

If you can't be passionate, don't make it a presentation. Passionate doesn't need to mean over-the-top, but it means speaking on the topic effectively and in a way that reflects believing there's a reason for these people to sit there and listen to you.

No one is forcing people to do presentations, but once you put people in a situation where they're expected to give you their undivided attention for a block of time, those are very reasonable table stakes.

There's always blog posts, articles, mailing lists, HN posts, etc. if you don't believe there's a strong need for people to set aside time consume your information in the form of a presentation.

None of this. It's in the blog post in a lot of detail =)

The 5ms write latency is because the backend distributed block storage layer is doing synchronous replication to multiple servers for high availability and durability before ack'ing a write. (And this path has not yet been super-performance-optimized for latency, to be honest.)

I like PlanetScale, but they already have precedent very recently for having a free-tier and then cancelling it for a minimum of $40/month plan, which made many people switch. What's to stop them from doing the same here?

Be wary of building a cheap hobby project on it expecting pricing to stay consistent. If $40+ isn't feasible for you, you may be trying to switch off to a hosted PostgreSQL option, with all the pain MySQL->Postgres entails, soon.

>I don't think anybody is "literally" envisioning things, as in hallucination

I think it's basically exactly like a hallucination for some people, except it's mentally tagged as originating "internally" instead of "externally" (which is what freaks people out about having a hallucination). I think it's basically the same thing with internal monologue vs. auditory hallucinations.

(for the record I have neither internal monologue nor visualization)

> indie software hasn't died because the notion of "purchase and own for life" isn't a sustainable business model

The worst thing is that it can totally be a sustainable business model. Many software giants of today grew to their size by offering "buy to own" products through the 90s and 2000s. Lots of software can still be bought through that model, especially games, and it seems to be going pretty well for the developers.

No, it's not that this model isn't good. It's that it's not enough. For nearly any large business today, the thought of not endlessly maximizing the profit for the immediate next quarter is appalling. The world-leading analysts have done their research, and the results are in: just like you said, brand loyalty doesn't actually matter for anything, and neither does brand perception or consistency. What makes the most money is using any means imaginable to hook people into a recurring payment, so that's what everyone will do once they get big enough. Nothing else actually matters in terms of money.

The Pixel 5 isn't supported anymore. The Pixel 6a still has a little less than 2 years of support left. These have become pretty cheap.

The Pixel 8 and 8a aren't that expensive either. And keep in mind that they are supported until 2030 and 2031 respectively. [1] They not only receive security updates for 7 years, instead of the 5 years for previous Pixel generations, but also have stronger hardware security, by implementing the ARM memory tagging extension.

Kind of telling that

1, the iPhone outsells every other category by 5-7x ratio, and the Mac (which includes everything from Macbooks to Mac Minis to iMacs) barely sells more than the iPad.

2, Services (iCloud, apps, music, TV shows etc.) now bigger than every other category, except the iPhone, combined

Basically 76% of the sales are iPhones and Services

(millions)

iPhone $209,586

Mac $33,708

iPad $28,023

Wearables, Home and Accessories $35,686

Services $109,158

Total $416,161

Next 5 years or so (or even less) both the iPad and the Wearables, Home and Accessories category will overtake the sales of Macs.

If they could answer those questions _before_ making fancy website with claims like "our breakthrough AI algorithms and hardware, which can run generative AI workloads using radically less energy than deep learning algorithms running on GPUs", they would be much better received. But they jumped to bombastic claims right away, so they now cause that scammy feeling. Hence the comments there.

> Short(ish) YouTube videos is simply not the right format for serious work, sensationalism or not.

I disagree. For example SIGGRAPH presentation videos manage to be short, informative, and largely non-sensationalist. You can see some of them in this playlist: https://www.youtube.com/playlist?list=PL1PdIP1lGMJJzRFjlDajK...

There are different levels of "counterfeit".

There's the clearly labeled and advertised GD32F103 style clone which is pin-compatible, supports higher clock speeds than the original STM32F103, but takes much longer to power on and has different analog characteristics, maybe some worse; not a problem.

There's the potential case where somebody sells you a GD32 telling you it's an STM32, either with the proper markings, with the markings sanded off, or with actually fake markings. This still might cause no problems, or might result in a problem that takes you a long time to track down. (Maybe you're unknowingly relying on, say, the hypothetical lower power consumption of a clone, so when you fab a batch with real STM32s, the product's battery life goes to shit.) You can detect this in firmware and may be able to come up with workarounds. Or, if your vendor is FTDI, they may sneak malware into their Microsoft Windows driver and brick your products months or years after you've sold them. They've done it twice.

There's the case where the clone is designed to act as much like the original as possible, so maybe you can't detect the substitution in firmware and can't work around whatever problems the counterfeit is causing.

Then there's the case where you ordered 10,000 STM32s in a QFN-32 and got 10,000 QFN-32s that say "STM32" on them but are actually PICs with a totally different pinout, or SRAM, or something else. These will not probably still work.

>most contracts have a provision about not contradicting the law

But is there an Israeli law that states contracts must be in concordance with foreign law... When the damages of an Israeli contract get evaluated in an Israeli court and they include the loss of Israeli intelligence assets will the costs not be significant? Yes google can pull out of Israel but they literally built datacentres there for these contracts so there are sizeable seizable assets.

And yes google may also get fined for breaking foreign law by foreign courts. The question is if the architecture of the system is set up so the only way data can be "secretly" exfiltrated by other governments is to go through local Israeli employees and they're the one's breaking the foreign law (and they were told explicitly by foreign bosses that they can't share this information wink) is there any punishment for google other than fines dwarfed by the contract and having to fire an employee who is strangely ok with that, who is replaced by a equally helpful local employee.

If you try to make ISPs pay for connecting to you, don't expect your users to have a good time reaching your services. And it's difficult to have a "frictionless" popular service if your websites are the slowest ones around.

To the contrary, the big sites want the opposite: they want all users to have as good connections to them as possible, which they achieve by being nice to ISPs.

MacOSX is a popular choice for dev boxes (if I understand correctly, they provide some pretty good tooling for managing a fleet of machines; more expensive hardware than a Linux dev machine fleet, but less DIY for company-wide administration).

... but Google solves the "A Linux fleet requires investment to maintain" problem by investing. They maintain their own in-house distro.

Modern brain imaging techniques also weigh in on this issue. Mental imagery corresponds to voluntary activation of the visual cortex[1]. The quality of the self-reported imagery corresponds to the degree of activity in the visual cortex[2] while imagining some visual scene. People with aphantasia have little to no visual cortex activity.

You can take once-in-a-lifetime experiences in your 20s and still save for retirement. I went to Burning Man and traveled to Amsterdam in my 20s and that didn't impact my savings.

I should point out that it's cheaper to travel when young: Back then I stayed in a tent in the desert and in a friend's room near Amsterdam. If I did the same trip today, I'd have my family in tow, and would need more comfortable accommodations.

I should also point out that startup equity is not retirement savings. Selling 10% of your equity, investing most of it, and then doing something that you won't be able to do when you're old is a very wise and mature decision.

You are literally uttering nonsense.

No one is blaming PG&E for all wildfires. We are blaming PG&E for the wildfires THAT THEY CAUSED. These fires could have been prevented if THEY BURIED THEIR POWERLINES back in the early 2000s when it was far cheaper and like they promised. They instead decided to ditch that and instead buyback stock and pay lucrative dividends.

Burying powerlines would 100% prevent wildfires which were caused by sparking or broken power equipment, which has been the documented reason why several extremely large and fatal wild fires were caused by.

i can visualize only faint wireframes and blobs, if that makes sense. the closest analog is, my internal monologue can speak, as if i were to physically speak, but i cannot "hear" it with my ears. i can visualize "where" each part of a composite scene should go (e.g., my laptop on a table, with a whiteboard in front of me, and a window to my left), and rotate a representation of the scene, but there is no visual component aside from a very plain outline, if i concentrate.

speaking to people who claim to be able to visualize colorful scenes in 3d, with sound, etc., and truly see the scene before them --- there is probably _some_ variance. i wouldn't say it affects my cognition, but how could i really know? i've never asked my friends, but i imagine the percentage of people who use 3d visualization to reason, e.g., complex math, is small, given the number of people i've seen use the right-hand rule on exams :) (especially given aphantasia is supposedly quite rare).

i attended a talk recently on experience with organic chemistry pedagogy at a university for deaf students. few requisite terms are defined in american sign language, so the professor formed a committee to create 400 or so signs. "tetrahedral" uses four fingers in a tetrahedral formation, "chiral" moves one hand about the other to simulate a mirror, etc. education of stereochemistry wasn't necessarily heavy on visualization, as you can draw the molecule and reason about it without conceptualization in 3d, but i caught that i'd often look at clocks for R/S rotation problems (where clockwise-counterclockwise in 3d was relevant).

There is an interesting reddit community 'CureAphantasia' with resources to develop your ability to visualize mental images. Together there are ca. 25 posts that offer a complete guide that might as well have been a book.

To some extent you’ve answered this yourself: TypeScript (and/or linting) is the way to be warned about this. Aside from the points in sibling comment (also correct), adding these kinds of runtime checks would have performance implications that I don’t think could be taken lightly. But it’s not really necessary: static analysis tools designed for this are already great, you just have to use them!

Trust is key, if you want legitimate whistleblowers.

Anecdote behind thinking a bit about this... I was discussing cofounding a startup that incidentally overlapped a bit with this space. One of the very top concerns was that we needed to be seen as trustworthy, to both employers and workers, and that trust would be a significant part of the value that we brought.

Then my prospective cofounder (a real straight-shooter) pointed out that one possible side effect of that trust (if we achieved it), was that workers might come to us with information about a company that we'd be obligated to report to gov't authorities, against the expectations of the worker. It was one of the many things we'd need to be very clear about, in course of earning and honoring the trust that enabled the good stuff we could do.

So when authors of history-related works criticize or make remarks about bloodlines such as the Hapsburgs or the Medicis or the Colonnas are you equally as outraged as when it involves a bloodline of Jewish people?

If I navigate to - https://en.wikipedia.org/wiki/Genealogy_of_the_Rothschild_fa... - every section of the page mentions the family being involved in banking. Am I stereotyping members of the Rothschild bloodline by saying they're involved in international banking? I don't think so.

I'm equally gobsmacked by people who claim we shouldn't utilize pattern recognition or who want to pretend stereotypes materialize out of thin air.

The good/bad part of modern consumer appliances is that they are largely giant computers with fewer mechanical parts to fail. They can be more reliable but when something breaks, it almost always requires replacing a main board that costs 25-50% of the replacement cost of the entire unit.

I've had two boards die on appliances this year. Fortunately, warranty coverage paid for the parts. So now I have a practically new refrigerator and furnace. At least until they fail again in 3-5 years.

Not parent but I think the link is pretty clear about what they want to say. I haven't got the time to actually watch the full video, but I could tell this is not a great presentation just by randomly clicking at random timestamps. And almost any presentation from Google (technical or not) I watched on YouTube is better than this.

If you really want me to explain it for you, and just one issue:

There are way too many words on your slides.

P.S. You should click that link and go through it again. If you still don't get it, try once more.

Yeah, this article feels like it's very much setting up a ridiculous strawman.

Nobody who knows anything about signal processing has ever suggested that the ear performs a Fourier transform across infinite time.

But the ear does perform something very much akin to the FFT (fast Fourier transform), turning discrete samples into intensities at frequencies -- which is, of course, what any reasonable person means when they say the ear does a Fourier transform.

This article suggests it's accomplished by something between wavelet and Gabor. Which, yes, is not exactly a Fourier transform -- but it's producing something that is about 95-99% the same in the end.

And again, nobody would ever suggest the ear was performing the exact math that the FFT does, down to the last decimal point. But these filters still work essentially the same way as the FFT in terms of how they respond to a given frequency, it's really just how they're windowed.

So if anyone just wants a simple explanation, I would say yes the ear does a Fourier transform. A discrete one with windowing.

Nice to see this passed around on Hacker News. I think the whole concept of lenses is super cool and useful, but suffered from the usual Haskellificiation problems of being presented in an unnecessarily convoluted way.

I think Accessors.jl has a quite nice and usable implementation of lenses, it's something I use a lot even in code where I'm working with a lot of mutable data because it's nice to localize and have exact control over what gets mutated and when (and I often find myself storing some pretty complex immutable data in more 'simple' mutable containers)
by adornKey | 2025-10-30 21:10:01+00:00
Yeah, but not only the frequency is important - the wave-form is very relevant. For example if your wave-form is a triangle, listerners will tell you that it is very noisy compared to a simple sinus. If you use sinus as a base of your vector space triangles really look like a noisy mix. My question is, if the basic elements are really sinus, or if the basic Eigen-Waves of the cochlea are other Wave-Forms (e.g. slightly wider or narrower than sinus, ...). If physics in the ear isn't linear, maybe sinus isn't the purest wave-form for a listener.

Most people in Physics only know sinus and maybe sometimes rectangles as a base for transformations, but mathematically you could use a lot of other things - maybe very similar to sinus, but different.

The fundamental purpose of google is to use the internet(and search for things to use) while viewing their ads. The rest of the google garbage are vanity projects to make people use the internet and look at more ads. The underlying technology that drives internet search is no longer rare (look at yacy or elastisearch) what makes google powerful is vast tomes of information about who buys what. With sufficient data collection any corporation would be capable of serving targeted ad campaigns at their users weakening Google's position. If google were to attempt to exploit ISPs, ISPs would simply use their control over the consumer to drive their traffic another search provider more than willing to service them for free and serve ads.

> People benefit from stuff like this

While I agree that people generally feel better by getting something with little effort, I think that there is a longer-term disservice here.

Once upon a time, it used to be understood that repeated use of a tool would gradually make you better at it - while starting with the basics, you would gradually explore, try more features and gradually become a power user. Many applications would have a "tip of the day" mechanism that encouraged users to learn more each time. But then this "Don't Make me Think" book and mentality[0] started catching on, and we stopped expecting people to learn about the stuff that they're using daily.

We have a high percentage of "digital natives" kids, now reaching adulthood without knowing what a file is [1] or how to type on a keyboard [2]. Attention spans are falling rapidly, and even the median time in front of a particular screen before switching tasks is apparently down from 2.5 minutes in 2004 to 40 seconds in 2023 [3] (I shudder to think what it is now). We as a civilization have been gradually offloading all of our technical competency and agency onto software.

This is of course leading directly to agentic AI, where we (myself included) convince ourselves that the AI is allowing us to work at a higher level, deciding the 'what', while the computer takes care of the 'how' for us, but of course there's no clear delineation between the 'what' and 'how', there's just a ladder of abstraction, and as we offload more and more into software, the only 'what' we'll have left is "keep me fed and entertained".

We are rapidly rolling towards the world of Wall-E, and at this pace, we might live to see the day of AIs asking themselves "can humans think?".

I used to go to office.com to use web versions of Word, Excel, Powerpoint.

Imagine my pleasant surprise (/s) when recently I went there, and the icons for these apps had vanished. Instead there was a giant gaping textbox for Copilot. A minute or so of staring at it, and I noticed a "Create" link on the left. That led to a page that invited me to do various things (e.g. "create a presentation", presumably with the web version of PowerPoint). The icons were still missing though.

Also notable: My work-issued Windows computer has Copilot, and Copilot 365. I have no idea which does what, and what's the difference between the two.

> A repl/notebook thing that is running on a .venv preinstalled with stuff defined in some config file.

So, create a project as a playground, put what you want it to include (including something like Jupyter if you want notebooks) in the pyproject.toml and... use it for that?

What do you want a tool to do for that style of exploration that uv doesn't already do? If you want to extract stuff from that into a new, regular project, that maybe could use some tooling, sure, that would take some new tooling.

Do you need a prepackaged set of things to define the right “bunch of stuff” for the starting point? Because that will vary a lot by what your area of exploration is.

Developers are typically motivated by net revenue which is more dependent on audience size than fees. That is, if you sell an app for $1, would you prefer to earn $0.70 on a million downloads or $0.99 on a thousand? (With the former you can buy a house, with the latter you can buy a laptop.)

And as you've pointed out, implementing support for third party frameworks and funding improvements to webGPU, wasm, etc is expensive. Even recreating the webOS UI would be a considerable undertaking.

> The biggest issue as you said is financing.

Exactly. I agree that it is technically feasible, my point is that it is economically challenging. Not impossible, just extremely unlikely.

> The best bet here would be replacing something like Tizen where a corporation is already investing.

It looks like the last Tizen phone was released eight years ago and the Tizen app store shut down four years ago. Like webOS, it lives on as an OS for TVs, but I am skeptical it can rebuild enough momentum to challenge Android or iOS.
