pen2l··on WASM Is the New CGI
A better example than Figma is Rive, made with Flutter.

Works well local-first, and syncs with the cloud as needed. Flutter space lends itself very well to making local-first apps that also play well in the cloud.

pen2l··on How I Built My Blog
Safari on MacOS, running on new apple silicon on a fairly souped up MBP, which I use for various computationally intense tasks.

Kind of amazed (and confused) really... that the thing which finally gives it a challenge is a blog homepage.

I'm disappointed. I'd long looked up to Josh for good UI/UX, but like a lot of other UI/UX folks who are left alone to their devices go too deep in their tunnels and at some point lose touch from where the rest of us still stand.

pen2l··on A Word, Please: Coffee-shop prompt stirs ChatGPT to brew up bland copy
I have a mathematician friend who studied mathematics at MIT and then worked in a research team at Google for some time. I caught up with him, and casually half-jokingly told him that I tried to understand some of his papers but I got nothing out of them.

And he replied, in earnest, that some of the papers are needlessly and deliberately complicated and obfuscated for a whole host of reasons (political reasons, career reasons etc).

This jargon-heavy circumlocutious academic speak you find often in papers, it's a gate-barrier... to keep out non-native English speakers, up-and-coming scholars? I don't know, but whatever the case, let's hope the outflow of papers written with LLM assistance takes a blow at the problem, when the corpus of literature is so diluted with all this that corporate-speak and jargon-heavy speak as a differentiator for in-group or whatever has a lesser incentive to exist.

pen2l··on Amazon is trying to trick me into signing up for Prime services
I remember once, what like 15 years ago or something, I got an email from some business that I was subscribed to that I’ve been unsubscribed and refunded some money as they see I’m not using the service I signed up for or maybe forgot about it and that I should reach out to them if I’m still interested.

Can’t even imagine that happening in this day and age. In fact big companies probably covet this demographic (subscribe and forget) and go to great lengths to secure them in their webs.

pen2l··on The Katsuification of Britain
It’s pretty “popular” in United States also, well at least in my group of peers whenever we’re going for sushi one of us will have ordered katsu curry.

My absolute favorite is the curry as it’s made by Yayume sushi in San Ramon.

pen2l··on Show HN: I made an AI image enhancer that boosts images 10x to 12k pixels
AI is gonna introduce new information to input new resolution from nowhere either which way, so we're just priming and massaging and optimizing our input so as to remove any obstructions that might trip up the AI enhancer. But yes you're right, ideally the enhancer should know how to take into account compression artifacts but this one doesn't.
pen2l··on Show HN: I made an AI image enhancer that boosts images 10x to 12k pixels
The original contains artifacts that tend to arise after compression, as the other poster notes (posterization and such). I wonder if you'll get better results if you make the original go through a gaussian to smooth those artifacts, and then feed it to the enhancer.
pen2l··on GitHub Copilot is not infringing your copyright (2021)
Suspend all knowledge of copyright law as it exists today for a moment and approach this hypothetical on first principles: a lot of GPL copyleft data is used in the making of an AI tool, that when asked for it, can itself recreate code similar to what was input... also, the creator of that AI tool will reap in all the profits without giving a single penny or even recognition of the value it guzzled from GPL data it was trained on to creators of original copyleft data. Is this fair? What do your scruples tell you?

No, of course not. We should probably revisit copyright law, given that it was written at a time when no-one foresaw modern AI tools, its capabilities, and its effects on creators and societies.

pen2l··on Rye: A Hassle-Free Python Experience
Given that you guys are in charge of both uv and rye, why keep two alive at the same time? Why not just kill rye now to avoid fragmentation, and confusion that comes with the burden of having to choose between the two?
pen2l··on Rye: A Hassle-Free Python Experience
Worth noting that the uv folks (https://astral.sh/blog/uv) have taken over reins from this Armin project.
pen2l··on Ask HN: what are examples of successful "open-source alternatives"?
DaVinci Resolve is great (I'm partial to all Adobe replacements; Resolve is indeed a great alternative to Premiere, and Pixelmator, Rebelle, Affinity, etc. are great replacements for Photoshop), but none of these are OSS.
pen2l··on First look at the upcoming Starlink Mini
The other disappointing thing (correct me if I'm wrong) is that it's not quite portable in a true sense; if I take the Starlink equipment I bought in United States to.. say, Argentina or Germany, it won't work there. I wish it could work like that, without a lot of hassle, but it doesn't appear to be the case.
pen2l··on Ask HN: Why is nobody manufacturing low tech electric cars in 2024?
Fancy screens are essentially low-tech now though, they've been commodified, Apple and Google will hook up car companies with that and it's not gonna cost them much. Bespoke buttons with soft touch is what is exotic.
pen2l··on Banana giant Chiquita held liable by US court for funding paramilitaries
I want to say something and I promise I say it not as a dig on you... as someone who's followed you for more than 10 years, I am fascinated that despite the many, many changes and revisions in your belief systems over the years, something that never changes is the certainty and conviction and confidence in your tone.

I guess it's a good thing, wish I had it. Makes for persuasive and effective writing, that's for sure.

pen2l··on Show HN: Tiny Chrome extension to disable images to reduce distractions
I've gotta share something -- so, I think I have a bit of an addiction with YouTube and I'd been thinking about how to shake it off. I didn't get round to it for whatever reason (blocks in modem settings maybe), but one day a month or so ago, if I went to YouTube, I saw this screen: https://i.imgur.com/OIL0jSE.png

Not extremely sure why this happens (I reckon it has to do with my use of adguard), but anyway I noticed I would just... move on, there were not icons to entice me that I could immediately click. And then sure enough, I found myself less hungry for it in the coming weeks.

This all happened by accident but boy o' boy, it works. I'm wasting less time on YouTube.

I similarly stopped going to reddit (the comments don't load on mobile, things become unclickable... I imagine this is a change recently made live to force users to login to increase engagement... ironic that it works out backwards to what their intent was).

Reflecting more on this on a weary weekend morning, about how many are unable to shake off these addictions, I am increasingly convinced of the poisonous effects of these distractions and cannot help but think that dire action is needed to curb these addictions with gov't mandated regulations.

I think price increase of tobacco products (with tax costs embedded in the price) were a great deterrent (better than the warning signs on the tobacco), so I suspect deterrents need be incredibly strong. Finding that balance and perspective, of weighing personal freedoms and recognizing the realities of addictions is going to be very hard, but I hope for the good of us we go somewhere with this and recognize the dangers for what they are.

pen2l··on AlphaFold 3 predicts the structure and interactions of life's molecules
The most moneyed and well-coordinated organizations have honed a large hammer, and they are going to use it for everything, and so almost certainly future big findings in the areas you mention, probabilistically inclined models coming from ML will be the new gold standard.

But yet the only thing that can save us from ML will be ML itself because it is ML that has the best chance to be able to extrapolate patterns from these blackbox models to develop human interpretable models. I hope we do dedicate explicit effort to this endeavor, and so continue the human advances and expanse of human knowledge in tandem with human ingenuity with computers at our assistance.

pen2l··on Evaluating M3 Pro CPU Cores: General Performance
Depends. Hardware-based ray tracing is pretty attractive. As soon as renderers start making use of it, you'll see render speeds practically double over the previous equivalent M2 machines and considering low power consumption and other things, for some the M3 quickly becomes a pretty enticing offer.

HN might be missing this part, but I'm pretty happy that product people are still at the helm at Apple. We're talking about cores and this and that, but if you go to, for example, forums for Redshift renderer and hear what users of _tools_ who do things with these cores are saying, they are salivating over the M3.

One of the sneakily genius things Apple seems to be doing is, it goes to developers of some of the most "popular" apps and works with them to make their apps work well. Behind the scenes it's working with Maxon, Autodesk, Adobe etc to make things run well, and the information it gathers from working with them informs direction of further R&D. Which is how we came to have hardware-based ray tracing and other things that will actually play a pivotal part in improving end user experience for power users.

pen2l··on OpenAI board lied about reasons behind Altman's firing

    When the board was asked for details by the team, they said they
    couldn’t provide a specific example because Sam had been so 
    deft—as if he had cast a magic spell on them.
I've read pg et al singing praises about Sam, about the magic he works. I saw the /results/ when he became Reddit's CEO for a few days ('a child's play' for him, by his own admission: https://www.reddit.com/r/AskReddit/comments/3cs78i/comment/c... ). But his magic is done mostly behind-the-scenes and behind closed doors. To be the fly in the room to see the magic spells he casts, see the Sam Altman distortion field...

pen2l··on Insanely Fast Whisper
Transcription speed and accuracy keeps going up and it’s delightful to see the progress, I wish though more effort was dedicated to creating integrated solutions that could accurately transcribe with speaker diarization.
pen2l··on WeWork Goes Bankrupt
I also don't know enough to say much of substance, it appears NYAG was looking at it for a bit but backed off: https://www.reuters.com/article/us-wework-newyork-investigat...

Either way, he is failing upward. With Andreessen Horowitz's blessings this time he's back to rent-seeking schemes, this time it'll be the small people who will experience his flare: https://en.wikipedia.org/wiki/Flow_(real_estate_company)

I expect he'll do it all in the open view, but again the mass land buying-spree he's been on, it can't help but invite disdain for the guy and worry for those who will be in his eye-sight.

pen2l··on WeWork Goes Bankrupt
I find it remarkable that he manages to escape the spotlight that SBF or Elizabeth Holmes received. I guess the guy knows how to play the hustler game better than all of them.
pen2l··on A fourth of U.S. health visits now delivered by non-physicians
Epic very much is poised to take over and every week it appears a new large healthcare center makes the switch to it.

I think the hard lesson everyone must learn eventually is that they have to take control of/become deeply involved with their healthcare as much as possible, because dragons are everywhere. For the average person acute care is not needed when they're thinking of reaching out to the doctor, and they shouldn't because elevating level of intervention can quickly result in shit: got a headache or a hip injury? The doctors will give you a plethora of CT scans and you end up with cancer. Got pain? They'll give you opioids so you end up with crippling addiction.

It's true on a national level: https://www.wesh.com/article/us-health-care-worst-outcomes-h... and at a local level iatrogenesis is seen abound.

Indeed, of paramount importance for us is to learn how to take care of ourselves by going back to the basics (avoid processed diets, increase fibre-intake, etc, exercise (for the strength gains, for the endorphins and cardio/conditioning, for better bone density so that the body can whether through injuries better), cultivate your link to a positive community so it is there for you in your time of need). And download Epic and learn about healthcare/medicines and take charge as much as possible of your own fate. But when faced with a truly acute problem, see a specialist doctor and follow their commands.

pen2l··on A fourth of U.S. health visits now delivered by non-physicians
In a very meaningful way the line between physician and non-physician had been blurring anyway.

There's a software called Epic which is used by virtually all large healthcare centers, and while most know it as a database system to store patient history and health records (problems and conditions they've been diagnosed for, lab work results, medicine they're currently taking or have taken in the past), it also has a little tab where a healthcare worker can put in some keywords, e.g. the symptoms a patient has, and Epic guidelines gives the health-provider an action plan for that patient, as well as guiding them with differential diagnoses for non-simple issues.

Of course for common ailments a nurse practitioner knows as much as a primary care physician anyway and their treatment plans wouldn't differ, but the thing is a physician basically effectively will also only follow one script that the healthcare/insurance system in-place allows for, that Epic will spit out also.

In the same way some of us see the task of building a CRUD app as something fairly unremarkable (owing to existing frameworks, existing 'best practices' etc), a physician's day-to-day work is really not challenging, and a "people-person" non-physician equipped with Epic software could arguably work to deliver equal or if not better healthcare outcomes.

pen2l··on Toyota’s Ammonia Engine
In 2020 Tesla overtook Toyota as the most valuable car company, which is of course ludicrous and stupid. But Toyota probably took a note at that time about the importance of PR puff pieces.

But indulging in PR puff shouldn't be the reason for outright dismissal of the ammonia engine. One thing that's undeniable is that Toyota understands cars, and particularly what kind of cars we really want. It knew EV's short range would be a problem (hence the plug-in hybrids which I think are the real winners -- you can actually get by without ever going to the gas station if you're just commuting for work, but yet you can still go on long trips no problem... there you go, Toyota solved EVs).

Toyota has working prototypes of ammonia engines, they seem to work, they do not emit carbon-based emissions and are highly efficient. It's built a good product and it knows how to scale and I expect it will -- but it also needs a working infrastructure for ammonia supply and needs to do PR work to pave the way for that. Ammonia is a decidedly good and clean energy source compared to current generation of batteries that are made from relatively finite resources, source their electrical power from questionable places depending on where you are, and some small question marks still remain about the accumulation of battery waste as EVs gain popularity. I, for one, am excited to see ammonia-based technologies for energy store and fuel.

pen2l··on Log is the "Pro" in iPhone 15 Pro
The guy in the video is Stu, not only does he have an impressive resume (https://www.imdb.com/name/nm0556179/ known for originality, e.g. he did Sin City's look), he is also the original author of MagicBullet, which is one of the most used software by people in the industry to do easy color work. If there's one person who knows about color work, LUTs in creative work, color encoding systems, etc., it's him so naturally he knows how to present relevant subject matter without nonsense.
pen2l··on Blackmagic Camera for iPhone
More than anything it's about color correction and color grading.

This video explains it nicely I think: https://www.youtube.com/watch?v=pAh83khT1no

If you are starting out with good data (e.g. 32bit exr workflow), you would be amazed how powerfully and easily you can control what you want and what the possibilities are, with tools like MagicBullet (which offer presets to get you the cinema look with just a mouse click). But if you work long enough in this area you can discover your own workflow and pull it off without these tools, e.g. play with hue&sat, white balance adjustments, the curves, introducing an S-curve for example, color wheels, etc.

pen2l··on Never-Ending Learning of User Interfaces
Pardon me that I'm somewhat off-topic but it seems tangentially related, the rant I'm about to go on --

When looking particularly at the evolution of MS Office, I often land on the view that UI peaked around 2010 and promptly shot down in ruins with the advent of flat design. It's flat design which went away from gradient textures on buttons which for preceding years familiarized us with the impression of button states, importance information, and a handful of other subtle things.

The stated reason was simple and understandable, the designs had needed to remain sensibly consistent when switching from small form factors to large ones, when resizing (or rotating e.g. when a tablet goes from horiz. to vertical, etc. But I'm not satisfied with this defense: it seems lazy, the gradient textures could have been retained. It would have required a lot more work by Microsoft/Google UI designers, but they chose not to step up to the plate by just giving it all up to go the easy road. At least Apple has had the courage to not take the easy way out.

pen2l··on Firm regrets taking Facebook moderation work
I get and appreciate what you're saying but I disagree because I think when the veil is a little bit lifted for a community of the mechanisms of moderation it is subject to, it both nullifies a component of chaos in its evolution and I think it hastens the path of progression by allowing a more clear-headed internal deliberation.

I think it is generally true that things get better and better values win when a community is left alone to their devices (pun unintended), what with the long arc of justice in the universe and all.

pen2l··on Firm regrets taking Facebook moderation work
You know who should really be doing the moderation work?

The very people in that very local community!

This is how this is supposed to work in a healthy and well-functioning society/community -- it moderates itself with internal deliberation about what the norms are and with reflection and awareness of how things are changing, with self-assigned community leaders and adults! The moment you outsource that important task outside the community is the moment you doom and cripple that community.

Because when it's some Kenyans far away doing the moderation then we here don't have an awareness of what's going on here and what the social climate is, how norms are changing, what the youth are up to. Forgoing this feedback loop which results in some measure of self-correction can't be good and that lag in cognizance will come to get us before it's too late to do much of the dangers lurking about.
