> That’s not to advocate for unfiltered internet access or anything, just presenting my experience as a data point and food for thought.

This 'food for thought' stands to mental health as McDonalds stands to physical health. You're trying to make the case that limiting teenager access to controlled substances is 'creating a controlled environment of which the person only will become aware when he leaves home'. This is, to put it bluntly, abject nonsense. My 14yo daughter - the 20yo does her own things by now but has managed to evade being caught by the machine, most likely in no small part thanks to her upbringing - knows perfectly well that her access to these 'services' are being limited, she knows why, she knows what the 'services' have to offer having seen her friends and others around her drown in them. She is in no way living in some bubble which she'll only recognise and escape once she leaves home.

Stop apologising for inaction in the face of the 'social' disease, this is like that well-known cartoon of the dog sitting in a burning room while he says 'this is all fine' or something along those lines. Things are not all fine and it is up to parents like us to find a way though the quagmire of lures and incentives because our children are too young and inexperienced to decide for themselves whether these are good ideas. We don't allow children to use drugs like alcohol either before they've reached an appropriate age, we don't feed them porn (although it is quite unlikely for them to have missed than the 'net is full of it so they're probably already exposed), we don't put them behind the wheel of a large automobile (to paraphrase the Talking Heads) and now we don't allow them to feed their developing brains to the machine. This is just another part of parenting the denial or refusal of which is just as bad as the denial or refusal to keep your children from the aforementioned hazards. A time will come when they are free to choose whether they want to partake of this madness but that time is not when they're 14 years old.

> the quality of the room wasn’t noticeably better than other places I’ve stayed

I broadly agree with you on their hotels. But I’d note that Four Seasons doesn’t compete on room quality, but service. If you planned your stay perfectly they shouldn’t outperform. But if you forgot something, or need help with something weird, they have a habit of being halfway legendary. (Colleague left his suit at home. They had one made overnight. Concierge apparently knew a suit maker’s cell.)

I fabbed a couple FreeEEG32 boards [1] recently and have half of a design for my own board put together.

This technology CANNOT effectively move a mouse around on a screen today, much less control robots. If it could, they wouldn't have to implant things in paralyzed patients' brains just for basic computer control.

I do think it's a very interesting field and there's a lot of improvements to be made. It's also extremely sensitive to noise (for best signal you can't be anywhere near mains power), any movement of facial muscles completely drowns out the brain signal, and getting electrodes prepped properly is time consuming and requires skill. And even in optimal conditions the SNR is not amazing.

I'm looking into dry, active electrodes as well as inter-electrode impedance detection to solve electrode prep, and a driven right leg circuit to help SNR. TI ADS1299 (ADC used by this and most other hobbyist EEG boards - directly targeted at EEG thus fairly expensive) has impedance detection and a DRL circuit but best I can tell neither is used by most boards [2]. I'm also interested in pogo pin electrode arrays for increasing spatial resolution.

Honestly most EEG boards seem, to me, more for show and money than anything else. No one even attempts to quantify noise levels, and they have very large margins for basically being breakout boards for ADC chips. (and $300+ for a fabric cap with passive electrodes???) And no one who says "look at all this stuff you can control with EEG!" has any projects of actually controlling anything with EEG, because it's extremely difficult. They just link to old papers where someone put together a control system slightly better than random chance.

Would love to collaborate on something here if anyone has any interesting ideas, I think hobbyist EEG could be done a whole lot better.

[2] This one does implement impedance measurement which is nice.

With plaintext, it's very trivial to add a script that put images in some location and build the link to that.

Markdown is great because you can easily add structure while typing compared to other format which have a more extensive markup format. I prefer org-mode because what Markdown can do, but also more extensive capabilities if you need so, but there's not a lot of editors for it especially on mobile.

I just don’t have any of these worries with Obsidian. I pay for it because it’s great software and needs support. The sync is amazing, totally solid. The data is wherever you want that data to be. It’s just MD files. You can adapt the tool to be whatever you want from a PKM system - massively complex, with some kind of dataview hell, or just some files in a hierarchy. You can use plugins or not use plugins. You can build your own. There’s no lock in. “Migration” isn’t really a thing - it’s some files in a folder system. It’s as future proof as it can be.

I mean go nuts and roll your own if you want, but really, what’s not to like?

John was used by Wikileaks, registered the original Wikileaks domain, was blacklisted by Wikileaks insiders when he started questioning their financial (and "other") irregularities, and ended up cryptome'ing Wikileaks.

His site was not Wikileaks, he operated with morals and integrity. An example of this is how he had questions about how Wikileaks was publicized as a non-profit, when it was a project of The Sunshine Press-- a for-profit Icelandic corporation. Then the Wau Holland audit lies, selective releases, excessive and unaccounted-for spending, and obsession with money and publicity were all targets of his criticism.

John could smell the rot from a thousand miles away.

> Tunkhannock believes it could save upwards of $1 million a year by switching to solar, money that could be used for student initiatives.

> “It was always a financial decision,” Suppon said. “We wanted to be able to offset our energy costs, produce our own energy and only pay distribution [fees] back to the grid.”

> There’s one catch: Tunkhannock’s plan to go solar is contingent upon winning more than $1 million in funding from the state’s Solar for Schools program. Currently in its inaugural year, Solar for Schools was born from a bill that faced an uphill battle in a legislature where environmental bills often die by attrition — a battle that required its creator, progressive Rep. Elizabeth Fiedler (D-Philadelphia) to reach across the aisle and help marry what are often competing interests in the state — labor, education and climate.

If they are really going to save $1M/year on a project that requires $1M, then they can easily issue a bond to cover this.

But those numbers are clearly exaggerated and I bet this entire idea is only going to be worthwhile at this latitude if the bulk of the capital costs are externalized.

Dropping a product recommendation -- my favorite spaced repetition + notetaking + learning app: https://www.remnote.com/

I'm not affiliated, just a big booster. For those familiar with Anki it follows the same conventions. It has an excellent system for managing cards. Adding cards is as easy as writing a bullet point: [front of card] == [back of card]. They got the ergonomics right and clearly know the space very well; it has the right keyboard accessibility and shortcuts and navigation. It supports the basics you'd expect like cloze deletions (fill-in-the-blank), image occlusion (cover up parts of an image). It manages assets like PDFs and images. It uses FSRS (the best SRS scheduling algorithm atm).

It has the best (optional) AI integration into a product I've seen except for the usual code-generation suspects. I'm learning spanish and can type into a bullet point something like "el vaquero ==< [tab]" and have the translation automatically generated for me into a forward and reverse card. I'm learning math and can cloze-delete parts of latex equations; the AI can very frequently generate excellent and accurate latex equations, which I can make small edits to as I'd like. These kinds of bonuses make taking live flashcard-based notes during my spanish tutoring sessions and math-based parts of classes feasible.

It's less low-level configurable than Anki and more "works out of the box" with a smaller extension system. I've had enough of trying to fiddle with Anki. Overall just excellent -- I'm not affiliated in any way. Development is very fast. Release note videos are incredible, minor updates occur ~weekly. I've run into a few bugs, especially when I was traveling overseas where internet isn't strong, but overall very pleased with it.

Kudos to the author for scratching their own itch.

People in a similar position might be interested in Joplin, which is indeed FOSS, and has lots of sync options. I personally use SyncThing, which keeps things free, but you can also use a number of other free cloud providers. You can choose to encrypt your notes to protect your privacy.

This is one of the reasons I ended up writing my own language study system. I haven't used the FSRS thing mentioned above, but I've heard it's much better, and having looked at the algorithm, it seems like it should be better.

The other reason I wrote my own system was to integrate SRS with extensive reading. Basically, my algorithm tracks the difficulty of all the words and grammar concepts, like FSRS; but then it gives you content at the right level for learning (either fewer than 5 new concepts, or an average of 95% known material).

And among the things that fits, it balances reviewing older material and learning newer material, based on what would have the largest impact. (Reviewing something you're about to forget has a bigger impact than learning something new, because the new thing you're going to forget much more quickly. So the balance of new / review and spaced repetition falls out naturally.)

I found out fairly quickly. I had a little argument about what time it was in London. I had supposed that time-zone conversion would not be a problem. However, LLMs are knowledge-bases frozen in time, trained up on a certain corpus of material and then isolated, and it was beyond their competence to actually know the current time-of-day. Sure enough, various answers were given that did not really correlate to anyone's time of day, much less correct time zones.

> Obsidian was a great tool for me personally for a long time. But I felt frustrated when I wanted to access my notes on my phone while on-the-go and saw that I had to pay for this feature.

I'm using Syncthing [0] to sync my vault between devices. On my main PC, Syncthing runs constantly in the background. Say, if I made a change, and want to send those changes to my phone, I open the application on my phone and let it fetch the changes. It's not perfectly smooth, like Obsidian's own integration, but I prefer this instead of setting a Git repository. Also, the files don't stay in a remote server.

> You’re trading votes and not every constituency gives a shit about the same issues.

But this is precisely how democracy fails. You have a bill that nobody wants except a special interest group in e.g. Pennsylvania. It can't pass on its own because it's not worth the candle -- Pennsylvania wouldn't even pass it themselves at the state level. But if the federal representative from Pennsylvania can get that bill funded with federal money then they get reelected in Pennsylvania. And likewise for some other bad bills from Florida and Virginia and Arkansas.

But then instead of all those bills failing as they deserve to, they get combined together and all pass, because the constituents in any given district are paying more attention to whether their boondoggle gets passed than whether their representative can prevent some other one.

What are the child safety considerations to be careful of, with blinds, and with openers?

(I recall seeing warning stickers and design changes on ordinary miniblinds. I suspect that one of the changes involved having multiple pull cords be separate and loose, rather than a fastened together or a single looped cord. But I'd guess that's not the only safety design decision.)
by colinnordin | 2025-05-18 17:52:49+00:00
I’m sure the algorithm can play a huge role in the effectiveness of learning but for me the difficult part was always creating the cards and actually opening the app to practice.

I've built Komihåg [1] to try and combat this: Select any text on your iOS device and a flashcard is automatically created for you, and the app is then showing you the cards on the Home Screen / Lock Screen / Apple Watch Face.

I haven't gotten to implement any sophisticated scheduling algorithm yet but will definitely do that eventually.

The truly scary thing to me is watching them start to believe the anecdotes they've stolen from people and presented as their own stories actually did happen to them, as they lose their marbles.

I've spent much of my life learning to tell when people are making things up, but telling when they genuinely believe something that's completely wrong is a very different skill.

It's especially frustrating when they change the narrative of a real story about something where there were multiple witnesses (e.g., my mom and my siblings), then come to believe the narrative, and then accuse us of conspiring to gaslight them.

On the one hand, I get why that would be disorienting and scary, to have a whole group of people telling you you're wrong about something you're sure you remember. On the other hand...karma?

> Obsidian charges $8 a month to access the same notes across multiple devices.

It's $4 actually, for the normal plan that works perfectly well for most use cases. It's also end to end encrypted, which is great. And it's not just about syncing for me, it's about a backup solution for the notes.

> I started to have concerns about the longevity of the plugins and app itself. Some of you may remember when Evernote aggressively limited free users to 50 notes, many users migrated their notes elsewhere. I was one of those users.

The great thing about Obsidian (in comparison to Evernote), is that everything is just a plain text markdown file on disk. You can open those files in any app. If Obsidian goes away someday, all your notes can continue to be edited in any plain text editor. Sometimes I open notes in VS Code, because there are certain things I just prefer writing there.

A relevant question is: how much effort did you put into retaining the relationships with friends that ended up 'drifting away'?

In my experience, people with kids go into a black hole socially and hardly ever reach out to do something together. Said otherwise: I always have to make an effort to go visit them, they never come visit me.

To a certain extent that is understandable, but to put the moral responsibility on the childless for keeping relationships intact is wrong.

Most people who have kids actively and consciously choose for them and the consequences of having to care for them. In those cases they effectively also choose that over spending time with friends. I would argue that they are then thus more to 'blame' for friendships 'dying' (although I would just say people grow apart by choosing different paths in life, which isn't as antagonistic as using terms as 'true friends').
Show HN: Vaev – A browser engine built from scratch (It renders google.com)
by monax | 2025-05-18 17:54:12+00:00
We’ve been working on Vaev, a minimal web browser engine built from scratch. It supports HTML/XHTML, the CSS cascade, @page rules for pagination, and print-to-PDF rendering. It even handles calc(), var(), and percentage units—and yes, it renders Google.com (mostly).

This is an experimental project focused on learning and exploration. Networking is basic (http:// and file:// only), and grid layouts aren’t supported yet, but we’re making progress fast.

We’d love your thoughts and feedback.

Sometimes it's fun to realize that if we all just decided dollars were worthless, they would be. There'd be nothing the government could do about it.

Crypto ain't it, though. Even the better-scaling blockchains still don't scale very well. I've heard of a few different mesh-network currency projects, and I wonder if any of them could scale by essentially giving each user their own blockchain. However, in a mesh-network currency, you still have to find a conversion path with enough capacity, and pay a fee at each step, so maybe that's not it either.

The word comes from Greek, θησαυρός - "a store, treasure, storehouse, treasury".

> The usage of "thesaurus" in English for a kind of book dates back to the first one by Peter Mark Roget in 1852

To nitpick, though of interest: The usage meaning a book of words organized by their senses indeed dates to Roget's use in 1852, as the parent comment says. An earlier usage is more generally a 'treasury' of knowledge (in book form): there was a Thesaurus Linguæ Romanæ et Britannicæ ... in 1565, a Thesaurus Linguæ Latinæ compendiarius ... in 1736, and John Stuart Mill in 1840 wrote about "A thesaurus of commonplaces for the discussion of questions."

Motor current is a workable, but generally unsatisfactory, proxy for torque when using heavily geared motors. Far better to measure output torque directly if you can, which is what's being done here using what is essentially a series elastic mechanism (itself a very common way of implementing torque sensing).

To elaborate more, current sensing is only "better" in an ease-of-implementation sense, in that a lot of motor drivers already have current sensing built in/easily added. For some applications this is good-enough, but in terms of estimating "real number" torque from current, it can take a lot of work to characterize for geared motors.

First, yes, everything you said is true. And especially when you’re supporting an older application designed around such SPOFs, you need those to be bulletproof. That’s completely reasonable. That said, a fair chunk of my work since the 90s has been in building systems that try to avoid SPOFs in the first place. Can we use sharded databases such that upgrading one doesn’t take the others down? Shared-nothing backend servers? M-to-N meshes so we’re not shoving everything through a single load balancer or switch? Redundant data centers? The list goes on.

I don’t think that approach is inherently better than what you described. Each has its own tradeoffs and there’s a time and place for both of them. I absolutely did see a lot of Big Iron companies marketing their giant boxes as the “real, proven” alternative to a small cluster of LAMP servers, though. I don’t blame them for wanting to be big players in that market, too, but that wasn’t a good reason to use them (unless you already had their stuff installed and wanted to add a web service next to your existing programs).

I wouldn’t run a bank on an EC2 instance, but neither would I ever buy a mainframe to host Wordpress at any scale.

Some examples I'm aware of (mostly in the language learning and especially Japanese learning space)

- subs2srs MPV script: create srs cards from subtitled videos, if you have subtitles tracks for source and target language it will fill them both in (though that sometimes has caveats, different languages may distribute the meaning of a line of dialogue over different subtitle lines)

- asbplayer chrome extension: inject extra subtitle languages into streaming services and create flashcards from them similar to subs2srs

- yomitan: browser dictionary lookup, primarily for bilingual dictionaries for Japanese and Chinese but also has custom dictionary support.

> the OS needs to provide some sort of hook into this capability natively for both maximum adoption and also ease of use (for both developer and end user)

I’m absolutely of this mind, but unfortunately it also depends on developers’ willingness to make use of these hooks, and it’s becoming increasingly uncommon for third party apps to have any integration or automation affordances, especially any specific to any particular platform. It’s become the norm to ship the absolute bare minimum, which is the lowest common denominator “it runs”.
