As someone who has seen this effect before, but was unclear how it was done, this article is very "and now draw the rest of the owl". They define a basic equation, it's about what I expected, but the end shader code doesn't use it in that form, and I found it pretty difficult to parse, I can't say I'm much better off in the end.

Try https://www.shadertoy.com/view/tftfzj

Isolate each of the additive sine functions by commenting out all but one and view the different elements. Sine wave left to right, Sine wave up to down, Sine wave diagonal, Sine wave circular - and then observe the resulting pattern is just the sum of the atomic parts. Play with it to learn.


The article sums up quite well which principles are at play here. The fun part it's suggesting (without words), is either to pick it apart and see what each part does, play around with the constants in there, or start from scratch and roll your own... (all with the Shadertoy linked below the article maybe?)

I would say most interesting texts (articles, books, school, ...) should leave stuff up to the reader's mind to figure out. That's how someone really learns. Versus pre-baked stuff like television etc.

If something does not resonate at first that's pretty normal. You could still take it apart and start investigating words or concepts that ring no bell, for example: waves, interference, demoscene, owls, Feynman.

Enjoy! ;)


What I usually do in 2026 is copy the code and article and have Claude clarify the unclear parts for me. then is ok.

But that's sort of the author's job: if they wish to publish an article on a topic, they should make it both comprehensive and comprehensible.

It’s early February. Have you really read so many articles you couldn’t understand in one month that you have a “usual” way of dealing with it? You should consider whether you would benefit from curating your sources better, or if use of AI as a crutch has already decayed your ability to understand stuff on your own unrecoverably…

Definitely a playground for whatever I find interesting, mainly game-related topics


To be fair, I remember visiting my aunt's house in the mid-2000s, who had a surround sound set up her husband had set up. It required three or four remotes to work and no one but him could ever get it working. I think UX has forgotten a few generations by now.


Has anybody ever been able to program a VCR ?


Although the trope is hilarious I think most people just don't bother since it doesn't matter to them. I never had a problem setting the time on my VCR and using it to automatically record shows while I was at work.


I remember having trouble with mine, often mixing up the various hours (clock time, start time, end time, recording duration). Yes it was not rocket science, but it was used not enough to remember how to do it, and the manual was never ad hand when needed.


Yes it was no more difficult than setting any other digital clock. Even today, my microwave, kitchen radio, and several other devices all read "12:00" because I just don't bother to reset them every time there is a power glitch.


It seems strange now how often the power goes out. I remember back in the '90s I could leave my PlayStation running for two weeks because I didn't have a memory card to save my progress in Syphon Filter or NASCAR Thunder '98. Nowadays I have to set up autosave on everything and make checkpoint safeguards or scheduled backups because the power flickers off and back on at least once a week. This, with much more power efficient devices than that old PlayStation and Panasonic CRT.


This can vary greatly across locations, even within the same city and the same power distribution organization.

Different neighbors, being on different circuits, being on a line that's more likely to have storm damages, can make a lot of difference in quality of power delivery.

I've lived in places where the power practically never went out, never experienced undervolt situations, etc. I've then lived less than a mile away from the same place and experienced seemingly monthly issues of all the clocks being reset at random times when I come home. Living closer to things like hospitals, fire stations, emergency operations centers, etc. seem to give the best indication of power reliability, at least from my personal experiences.


It tends to happen in the area in general where I live. My house, neighbour's house, a house a mile away, all have the same trouble. I live within about six hundred yards of a volunteer fire department and about seven hundred yards from an elementary school, and even they've complained about how often the power goes out. The worst part is it's not like it's off for a few minutes and then it's back on. It's a momentary tenths of a second thing, like someone flicking a light switch down and up once to get people's attention.


Programming a VCR was pretty trivial for me as a kid, but a bit annoying.

But then VideoGuide [1] was released (available from RadioShack). I begged my parents for that and honestly it was the most amazing product and worked flawlessly. I felt like I was living in the future.

I was so happy when we got a VCR+ enabled VCR. Stupid simple to program. Just punch in a few digit code in the TV guide magazine and it would schedule it automatically.

https://en.wikipedia.org/wiki/Video_recorder_scheduling_code

https://www.youtube.com/watch?v=wkXQqVMt6SE

The last couple of VCRs we owned even had automatic time setting. It read extra data in the vertical blanking interval from our local PBS station.


The last short lived generation of VCR we owned had an on screen menu/UI driven by the remote control for setting time and programming a scheduled recording rather than arcane and tedious sequences of button presses.

I was surprised that kind of thing wasn't much more common earlier - it wasn't really any new tech breakthroughs so much as someone just going to the effort of building it.


Sure, but uncle (who drove a truck for a job) sat down with the manual for several hours one night and figured it out. He was probably the only person in the entire town he lived in. Most people could have as well - but it would mean spending several hours of study and most people won't do that unless forced (and rarely even then - see all the tropes about homework...)


I mean that's exaggerating. I did it, it took maybe 10 minutes following the examples in the manual. It was not very intuitive though, so if it wasn't something you set up often you'd always have to go back and read the instructions again the next time.


I'm going from memory (i was a kid and he is dead so no wap to verify) but hours stands out. Remember he was a truck driver not someone used to reading technical documents. We also don't know which vcr's - yours might have been easier than his, or your program simpler).

who is right - no way to know, everyone can make their own judgement.


My grandmother figured it out enough to make sure her favorite soap was always taped. It was a "set it up once and mostly forget it" thing, with the real hard part forcing grandkids to stop using the TV during the hour it taped to avoid accidentally taping the wrong channel. (VCRs at the time had their own tuner for OTA and that shouldn't happen, but her stories were important enough to her she didn't want to risk it, and had risked it in a brief period of having a cable box passed through the VCR.)


In theory, HDMI CEC should solve a lot of those problems. Unfortunately it only introduced another buggy layer.


But that was the niche, "elite" experience. Today, a "smart TV" is the norm.


Reminds me of HitClips from the early 2000s

https://en.wikipedia.org/wiki/HitClips

I remember being quite entranced with one that a neighbor had. It feels like a bit of a silly format now, but perhaps it's time for a resurgence.


It's not quite as stylish as these, but my personal favorite video game site was the Super Smash Bros. Brawl blog site, which had its heyday around 2007 or so.

https://web.archive.org/web/20071001132450/http://www.smashb...

It was the first time I had ever seen pre-release information about a game, and I checked the site religiously. The game director himself wrote all the posts, and it felt like a revolutionary way to get me excited about the game.


That blog definitely established character reveal drip feeds as the way to build hype for a fighting game (or similar genres like hero shooters), even today when it involves stupid things like announcing Ronaldo for the new Saudi-funded Fatal Fury.


It's part of the strange history of Sega. Even back in their heyday, Sega of Japan had a pattern of treating its American and European offices as subordinate, yet the founders of the company just a few decades earlier were Americans


I see this sentiment a lot, but I never agree with it. Sure, some of their projects seem very odd for them to lead, but given that they are completely reliant on their competitor for cash -- a revenue source that has been threatened several times by anti-trust cases against Google -- they should be looking to branch out. Firefox alone won't pay the bills, so they need to try and find some other revenue source. Plus, Chrome has essentially won. Not necessarily for any engineering reason, at least not these days, but from continued momentum of being the market leader. Sitting around quietly isn't going to get people to switch, they do need to find some way to distinguish themselves apart from Chrome, which again leads to these misc features being thrown out there.

The AI inclusion seems like the same reason everyone else is adding AI, they don't want to be left behind if or when it's viewed as an essential feature.


> Chrome has essentially won. Not necessarily for any engineering reason, at least not these days, but from continued momentum of being the market leader.

Ah, how the young forget... Mozilla became popular precisely due to their willingness to challenge the market leader at the time [1], namely, Internet Explorer. Going against the market leader should be in their DNA. The fight is not lost just because there's a market leader. If anything, Mozilla is currently losing the battle because the leadership doesn't believe they can do it again.

I'm fine with Mozilla diversifying their income, but I'm not fine with Mozilla sacrificing their browser (the part we desperately need the most) in the name of a "Digital Rights Foundation" that, at this rate, will lose their seat at the negotiating table.

[1] https://en.wikipedia.org/wiki/Usage_share_of_web_browsers#/m...


They were losing because MS bundled IE with every device. Eventually they MS lost an anti trust case against it and it opened up the market, which is before that graph begins.

Well 30 years later we are back where we started.

Chrome is where it is because it is preloaded on most phones on the planet (the other ecosystem has a different preloaded browser). The other thing is that it was advertised on the most visited page on the internet for 20 years.

Most internet users don't even use desktop/laptops, they use mobile devices and likely have no idea there is any other option than chrome.


Exactly, this is just about the most lucid explanation of the market share graph I've seen on HN. It's baffling to me that the rise of Chrome, distributed via Google, on phones and on Chromebooks, somehow doesn't enter people's explanations of market share change when talking about Mozilla. It probably the biggest single driver of market share change by an order of magnitude.


> They were losing because MS bundled IE with every device.

They weren't losing, they had 10x the market share they have now. MS lost an antitrust case, they weren't forced to do anything even after they lost, and big tech learned (correctly) that there was not ever going to be any serious antitrust enforcement on platforms.

Chrome came out with a heavily marketed browser that some people liked (but was far more marketed than loved.) Firefox then intentionally destroyed its own browser to make it a wonky clone of Chrome, even down to trivial cosmetic features and version numbering. Firefox's strength was its extensions ecosystem, so it took special relish in destroying that, and joy in painting the users that were bothered by this as stochastic terrorists. They claimed that the perpetual complainers just didn't understand the "normal users" of the market while Firefox shrunk from 30% of it to 2.5% of it. Meanwhile, they took to forcing bizarre, unhideable features that should have been extensions, and doing bizarre marketing experiments.

> Most internet users don't even use desktop/laptops, they use mobile devices and likely have no idea there is any other option than chrome.

Firefox gets all of its margin from Google, and is 2.5% of the market. There isn't really another option, no matter what Mehta says. Firefox gets more than all of its margin from Google - Google cash allows it to blow money on goofy money-losing projects that look good on resumes. Meanwhile, Wikipedia has 100x what it needs to run in the bank, entirely from donations, still keeps dishonestly begging, and still keeps collecting.

But Firefox claims that's impossible. It has to be fully dependent on Google because reasons, and those reasons are that it chooses its direction based on Google's desires.

edit: the craziest part of this common argument about Google bundling is that Google doesn't have anything like the monopoly that Microsoft had, Microsoft bound its browser to everything it could figure out how to, and Microsoft was still losing a huge section of the market to Firefox. The idea that Google is some special impossible challenge when Microsoft owned every computer is insane. It's impossible to beat Google when they pay your salary.


It's worth noting that Chrome was just legitimately a good product in a space where the competition wasn't blowing any minds. The people that switched over saw how much better a browser can be and spread the word.


Allowing the user to pull tabs into its own windows and merge them back was magic back then, as was including search and url in a minimalistic bar, when other browsers had 3-row bars at times. Such a simple and elegant product.

How the mighty have fallen.


For sure.

For a couple years Chrome was noticeably faster than IE/FF which is what caused tech oriented people to switch.

FF and even IE closed the gap for a little bit but once Chromes dominance took old I imagine the fact that no one tests things on FF any more has probably caused it to slip performance wise.


It wasn’t challenging the market leader that made them successful. It’s because Firefox was precisely a better browser at the time, and their marketing/activism around open web standards was great. There were lots of “challenging” going back then.

But simply challenging isn’t enough. People like to tell this tale where just being an underdog gets you some benefit. But it doesn’t. Firefox was way leaner, opened faster, had extensions, so on.


> Mozilla is currently losing the battle because the leadership doesn't believe they can do it again.

I do not believe that this is the case. Their #1 revenue source is Google. The moment they start regaining any foothold?

Imagine just collecting that amount from Google as tax, and funding Mozilla publicly.


There is no possible way to compete against a competent trillion dollar organization that knows how to build a good browser, and exploits its global monopoly position in search to advertise their browser.

It doesn't matter if Firefox became better. There is simply not enough differentiation potential in the core browser product to win by being better. Its all marketing.

I just wish Mozilla sold some stickers/themes as proxy donations and became largely independent.


> they should be looking to branch out. Firefox alone won't pay the bills, so they need to try and find some other revenue source

They probably would've achieved enough to sustain Firefox development in perpetuity if they invested most of Google's money in a fund.


They do exactly that! Their endowment is now $1.2 billion and its year to year growth is one of their strongest non-Google revenue streams.


> Plus, Chrome has essentially won. Not necessarily for any engineering reason, at least not these days, but from continued momentum of being the market leader.

s/Chrome/Internet Explorer/g

Nobody has won until the match is over, and history has a very long tail.


> Chrome has essentially won. ... Sitting around quietly isn't going to get people to switch

You hit the nail on the head with this one


I see the point, but them following the leader on this does not seem like a recipe for success. They aren't going to be as good at AI as OpenAI's browser, and their users are going to be less bought into it. I would have hoped they'd have learned their lesson from things like FirefoxOS but I guess not...


The amount of money they get from Google is vastly more than it takes to hire a few dozen people full-time to develop a web browser and email program.

People in the organization are trying to use what's left of the name recognition and all that money to benefit their own initiatives.


> The amount of money they get from Google is vastly more than it takes to hire a few dozen people full-time to develop a web browser and email program.

You under estimated the work to develop a web browser. Vivaldi are 60 people.[1] They produce an unstable Chromium fork and email program. They couldn't commit to keep uBlock Origin working.

[1] https://vivaldi.com/team/


That's a good example. I'm probably significantly underestimating the amount of people needed. $500M can hire a lot of $250k salaried engineers, though.


> $500M can hire a lot of $250k salaried engineers, though.

$250,000 is conservative for the total cost to employ a software engineer in the US. And their expenses are not limited to software engineer salaries of course.

A fair question would be what Google or Apple spend to produce their web browsers. The answers are secrets. $1 billion is a common Chrome development cost estimate in my experience.


What would you say is the most costly initiative that's siphoning money away from core browser development right now?


Good question. Looking at their expenses, though, it seems to be just a plethora of piddly donations. $1M here and there, and it adds up. That does fit with the lack of focus narrative.


"Range" here refers to a range of products, in this case a collection of Matter supported devices


"Products" would have had no such ambiguity.


I really wish ShaderGlass supported Linux. If there's a good(ish) alternative that anyone knows about, I'd love to try it out.


Unless "coal generating station" means something in particular, this isn't true at all, there's around 200 coal power plants in the US


They mean station powering California, not in the US overall.
