yes, exactly. Access/modification of a directly addressable byte is much faster than some bit of it.
If I'm not mistaken, on Win32 `BOOL` data type is defined even worse to a 32bit int (this C API was devised way before `bool` has made it's way into C), so 8bits isn't even the worst case scenario :D
It feels like this issue have been (at least in academia) known for a long time. When I try to explain the problem I usually use the slides from ICML 2018 talk by Yisong Yue[1]. And there's already (hard to use in practice) methods such as DAgger to correct for that accumulating error.

Out of the more recent advancements, I think ACT[2]s approach seems like the more interesting direction. Similar to MPC that predict(calculate) not only the next action but predict sequences of actions, discard all the actions except for one, at each loop.

Mapping the input to only the current action seems to be prone to error, while mapping the multiple steps is more robust.

My hunch is that there's probably some pretty fundamental limitations to our current methods (Transformers etc) though, which makes applying it to things such as language when error accumulation is essentially neglible (relatively speaking) fine but, to cars and robots maybe not.

With SMS otp, it's possible to associate 2 phone numbers (or more) to a single account.

That way if my wife and I can use her Amazon account.

Can the same paradigm be grafted to pass-keys/webauthn?

Maybe a useful flow could be

You can log in with any of the following:

a) passkey
b) email and sms and password verification
c) customer service

Its not 100% air tight; but it seems better than the current state of affairs.

This is not "simple". And I'm not even talking about tracking, why is `all.js` a whooping 1 MB of JavaScript? For example, it clearly includes markdown-it but the website has zero Markdown support as far as I can tell. Spell-checking is the only non-trivial component I can imagine and even that can be plausibly replaced with a native `spellcheck` attribute.

I would instead recommend a beautifully golfed, and yet still quite readable and functional notepad app with <100 bytes of JS: https://xem.github.io/postit/

There are some things I don't quite understand with passkeys.

People say it's meant to replace login/password, not act as 2FAs. Yet last I tried on Google having a login/password is mandatory, the passkey is just used as 2FA. So what's the point to convert my 2FA yubikey to a passkey?

Also, my understanding is that passkeys are standalone keys. There doesn't seem to be any support for federation of various keys by having them signed by a master key, as in PGP, so that I can actually prove on service X that I'm also the same user on service Y, thus being able to link or verify accounts easily.
No clue what you mean, browser cache might even clear itself without you doing anything manually. This thing makes no sense.

Nowhere ever did it say Tech Demo anywhere, not in the HN headline, not on the page itself. No, thanks. And even as a tech demo, there is nothing impressive going in.

I'm on a thinkpad x230t from over a decade ago, running Linux. It is a bit less vintage than yours, but I can confirm that for the princely sum of £200 on ebay, I can run a window manager and pretty much any software I want.

It replaced a £1500 starbook, which stopped powering on about a month after the warranty expired.

There was plentiful supply of cheap labor of other immigrants like Slovaks, who were even below Irish in the pecking order and not inclined to establish own businesses.
For me i've felt Samsung flagships have the best hardware, OneUI is very good compared those TouchWiz days. Then you have these bloatwares, first thing i do after getting any Samsung phone is doing `pm uninstall –k ––user 0 <bloatware.apps>` the linked tool does the same in a more user friendly way. One thing which that still blocks is i see you can't still remove some things like samsung account stuff, knox related stuff..etc, unless you flash a custom rom.

Is it something USA-specific?

I'm from Europe, I don't have FB account, but I have (and use) Instagram one.

I didn't seen any viagra, drugs or weed/CBT advertisements once.

I see many legitimate advertisements, and lot of ads of fake outdoor and motorcycle gear (to good to be true, like undestroyable sneakers and tracking boots for 10 euro, suspicious outdoor pants for 5 euros, better-to-avoid motorcycle protective gear, etc). And I'm interested in outdoor and motorcycle gear and equipment, so this ads could be named "well targeted".

Also not-so-often there are ads of AliExpress (and in last year Temu too), of course, but they are not worse than "everything under 10 euros" brick-and-mortars shops, same cheap crap (I don't say all you could buy on Ali is cheap crap, I've bought a lot of good items here, including sometimes unique things which you could not buy locally at all, but ads use very low priced crap mostly). Again, I'm using AliExpress all the time, so these ads are not completely mis-targeted too.

Never any drugs, dietary supplements, etc.

And everybody in this thread say that they experience these obviously illegal ads.

Speaking of which, Dewdney recently passed away on March 9th but I haven't seen any notice of it on HN or other CS-related sites. I know he alienated a lot of people with his unfortunate turn to conspiracy theory after 9/11, but he really contributed a lot to popular interest in CS and recreational mathematics in the 1980s and 1990s through his Scientific American articles and his books.
how exactly do you know this and why come on here and state it as a fact?

its a dubious claim at best, and if it were true would require asking the elephant sized question in the room - why collect my data if you arent going to use/sell it anyway? is collecting ny data just a fun internal project at Apple?
Cache coherence across accelerators lets you pretend you have one large unified memory similar to what apple does. It means you can easily share pointers between CPU and GPU with zero regard for how to move the data around and still be efficient. This is irrelevant for AI since AI does well with primitive DMA. You absolutely need CXL to have a viable OpenCL 2.2 implementation.

The best definition for "unit" in unit testing is the test itself. The test is the unit - as in, each test is testing a unit of code and doesn't interfere with other tests or rely on the external environment.

Too many times have I been told a class or a method in a class is a unit. It makes no sense and is the reason for excessive mocking, because they end up trying to isolate that class as an arbitrary unit.
A bank based in my region, one of the biggest in Europe, uses IBM mainframes and has hundreds of thousands of COBOL programmes. Their availability is disastrous. They need to regularly reboot LPARs (logical partitions of the mainframe) because they're so brittle, resulting in a segment of the clients unable to use online services. And on the other hand, services that need to stay available, like websites or instant settlement, obviously don't run on mainframes. That means that the website is up... but only displays a maintenance message.

As someone who is doing robotics and behavior cloning for a while, it’s incredibly funny to see the self-taught genius rediscover what’s been known in the field for 30 years and can be found by walking in to the first two lectures of any decision making/control theory class.

In practice, deep learning based behavior cloning works when there is enough data for the model to interpolate to the next “frame”, the proof of which is GPT and other LLMs whose primary training objective is practically behavior cloning. However, adding a neural network means there are some hallucinations, which can range for silly (for LLMs) to murderous (for self driving). However, this presents a huge opportunity as well, in that anyone who can solve hallucinations can make headway into not one but two billion dollar problems at once.

How to mess with your roommate (2018)
The article says

`Analysts clash on Supermicro’s ability to hold on to its position longer term. Wedbush analyst Matt Bryson said, historically, no company selling servers has had more than 30% market share.

“There’s not a reason Dell can’t do exactly what they’re doing,” Bryson said.

Others aren’t so sure. Some analysts say that established competitors will have a hard time bringing new products to market so quickly and have larger revenue streams from software and services.

Supermicro is trying to gain further market share by doubling down on AI and continuing to ship its servers out quickly. The company is also keeping prices low to entice new customers: Its gross profit margin totaled around 15% in its latest quarter, down from 17% in the previous one. HPE, by comparison, had gross margins of 36% in its latest quarter.`
Absolutely. I wasn’t suggesting that any of it is illegal. But it is concerning that ad targeting is potentially being used to make people think they need to be on medications that normally they might not seek out.

E.g. I’m not overweight by any means, but I’m also not 5% body fat. Could wegovy help me get ripped abs? According to these ads, yes! I have actually considered trying it just for the hell of it (and out of curiosity for how it works). But it’s definitely not medically necessary (or recommended) for someone like me, but these companies will advertise and prescribe it to me anyway.

Honestly I don’t think open access to these drugs is necessarily a terrible thing, but the advertising aspect I disagree with. I’m fine with anyone using Adderall for example if they seek it out on their own, but it makes me uneasy to think people are getting prescriptions because of the ads rather than because they were seeking it out on their own.

So many students on every level of higher education, probably even starting from high school, are now using chat GPT. Does this make education a crime?
TL;DR:

* Scale the time series data and quantize the floating point values into B bins.

* Each bin becomes a corresponding token id in a vocabulary of B embeddings.

* Train a small LLM to predict the next token id given a sequence of token ids.

* At each time step, the LLM gives you a probability distribution over B bins.

If it's not medically necessary, we won't prescribe (though I'm sure there are businesses who might).

I get your point, I don't like advertising medications either, but there are some specific cases (like testosterone deficiency!) where someone might be tired all the time, irritable, gaining weight, etc and not realize that these symptoms have a common cause. I agree that these cases are few, though.

In PHP, dependencies are just .php files just like your own code, it all works the same.

PHP code is also typically far less complex than Python modules - modern PHP code consists of a single index.php with procedural code, and everything else is just class / function definitions, so there are no side effects.
"No one in their right mind is suggesting Samsung. Heck, similar to Apple, you have swaths of people warning you about Samsung."

Apple and Samsung are the two most popular phone brands in the world, so it's not like "everybody knows not to use them" as you suggest. Actually, it's the complete opposite.
Hashicorp gave away basically everything valuable they had, and charges extortionate prices for the few features they've paywalled. Only way they're going to survive is by becoming a feature of some bigger cloud offering.

We've been leaning into Terraform-based Crossplane providers recently and the out of the box experience is so much better than using terraform cloud once you get crossplane set up, I can't imagine ever going back to vanilla terraform pipelines, and certainly not paying for terraform cloud.
In Canada, Samsung phones sometimes have the Facebook app pre-installed, but that can be disabled, and won't show up again. Besides that, there's no bloatware on my phone other than the default Google apps (Google Meet, Google Pay etc).

This sounds vastly more complex already than following a linked list. You've also ignored the other cost which is getting the stack trace data out of the program. Anyway I'm keen to see your implementation and test how it works in reality.

Just before the section on Moore's Law, it says this about silicon purity:

> Electronic grade silicon (EG-Si): 99.9999999 pure ('nine nines pure') Thats one impurity atom in every 10.000.000 silicon atoms.

I believe that should be 1.000.000.000 (10^9 atoms) to correspond to nine nines pure. Just as one impurity atom in every 100 (10^2) atoms would be 99% (two nines) pure.

Whether imitation works as expected depends on your mental model of what the person/thing you are imitating is doing, otherwise you won't actually be copying.

If you wrongly assume that the person is deriving an absolute steering angle from the image then you will fail.

Yup, no realtime communications of any sort, even texting, with people living in the Mars cities.

> this stuff is hard to explain to end users.

Is it? While I'm a developer I have zero knowledge about passkeys. (haven't even read the linked article. Which is usually not a badge of honour, but in this case ensures that I'm as much an end user as one can be.)

I logged in with some website on my phone. The website asked me if I want to use passkeys and told me that means I can log in using my fingerprint/face id. I clicked yes. Scanned my face as I always use to open my phone. That site is now authenticating with my face.

Didn't feel like it was hard to explain to me. It felt all quite straightforward to be honest.
What about OpenMao?

Ask HN: Knowledge-base site using VSCodium/FOAM/MkDocs
Hello HN -

I'm using VSCodium (open-source VSCode), with the FOAM plugin (similar to Obsidian / ROAM) to create a cross-linked notes/knowledge base. If you haven't tried it out - it's easy to setup, and works great.

It's like Obsidian... but open-source.

The next step I'm doing is to publish those notes as an HTML site. MkDocs-Material is perfect for this. The difficulty with using MkDocs & Markdown files with [[MyTopic]] links, is that MkDocs doesn't know how to automatically link to other pages. Fortunately, there is a MkDocs plugin called RoamLinks, which automatically converts the [[MyTopic]] links into HTML links to other pages - no matter where they are on the filesystem (very cool!!). That "unblocked" me - one struggle I was having when writing, was that I was renaming files & re-organizing - but that resulted in tons of Markdown links being broken - a huge chore that made writing un-fun. Now I can just "bracket bracket" any term that I want to reference/write later, and its good to go. Basically - its working great.

(Approximating the experience of Obsidian Publish)

The problem I'm having now is, when I do NOT have a page written [[MyNewTopic]], MkDocs/ROAMLinks can't link to the (unwritten) page. Instead, it outputs the text quite literally, as "[[MyNewTopic]]", with the brackets. Quite ugly. I'd love to have MkDocs/ROAMLinks NOT generate links for those pages AND hide/suppress the "[[ ]]". - I did a quick search on this (including ChatGPT) and the suggestions were. (1) Write a custom markdown renderer, before being processed by MkDocs, (2) create a custom MkDocs plugin, and (3) HTML post-processing (scraping out the [[ ]]).

One of the benefits of the VSCodium/FOAM/MkDocs/RoamLinks stack is that it basically "just works" - I write, run MkDocs build, get a website, and can `aws s3 sync` it to a AWS bucket, and the site is live. The only "glitch" right now is these dannnng brackets

Can anyone suggest a better way to suppress the [[ ]] for links which don't exist yet?

I'd also love to hear others' thoughts on the "open-source, cross-linked notes, published as a searchable website" stack.

Thanks!
