I used Julia for 4 years. I'm not a moron: I'm familiar with how it works, I've written several packages in it, including some speculative compiler ones.

You claimed:

> Allowing invokation of the compiler at runtime is definitely not something that is done for performance, but for dynamism, to allow some code to run that could not otherwise be run.

I asked:

> why not just compile a static but generic version of the method with branches based on the tags of values? ("Can't figure out the types, wait until runtime and then just branch to the specialized method instances which I do know the types for")

Which can be done completely ahead of time, before runtime, and doesn't rely on re-invoking the compiler, thereby making this whole "ahead of time compilation only works for a subset of Julia code" problem disappear.

Do you understand now?

My original comment:

> The problem (which the author didn't focus on, but which I believe to be the case) that Julia willingly hoisted on itself in the pursuit of maximum performance is _invoking the compiler at runtime_ to specialize methods when type information is finally known.

is NOT a claim about the overall architecture of Julia -- it's a point about this specific problem (Julia's static ahead-of-time compilation) which is currently highly limited.

i get your point, but i have a different experience. i also believe you are missing that once you made friends, switching tracks will only make it slightly more difficult to keep in touch. i didn't make many friends in school, but the friends i did make were not limited to my class and track. i can still see them during breaks, and we still share the same routes to and from school, ad we may still participate in the same extracurricular activities or clubs. those things would not change when switching tracks.

separate physical schools however may mean that i may never see some of these friends ever again. different school routes (even if we live in the same neighborhood). no chance to meet in breaks, etc. that's a whole different world.

I also believe that in order to bootstrap a viable system, start with system 1. The OP is partially sniping at people who creating all kinds of elaborate structures for systems 2-5, without attending to the first order of business, which is system 1. I've been guilty of this myself.

But it's easy to find dysfunctional organizations that focus almost exclusively on System 1, and it looks like grinding, hustle, "doing the thing", being stuck at CMM Level 1, and in my experience, it leads to burnout. So there has to be a balance.

You may certainly make the argument that a sizable guerilla urban force could perform outside their weight class against a federal army. However, it makes no logical sense to assert that most liberals buying guns do so under the theory that they will organize together against their government, nor that they do or should believe that this piece of military wisdom would work out for them.

I.e. it's obviously reasonable to believe that private firearms cannot stand up to the federal government, regardless of whether it is the case under theoretical conditions.

Why would I want you to manage it? Are you making a phone I want to buy?

Just because I'm happy with some corporations having a scan of my driver's license doesn't mean I'm happy with anybody having it.

Are you already storing the details of millions of others, and mine is nothing special? Are you a publicly traded corporation accountable to shareholders? Are you a nation-state with procedures around all these things? Or are you a criminal trying to sign up for credit cards in my name?

Your supposed equivalence isn't an equivalence at all.

RSS hasn't gone anywhere. Every podcast my podcast player downloads is announced to it either via RSS or Atom feeds. It has just fallen by the wayside as the way people become aware of updates to websites with serial publication of content (in general: because most people get that information from peer-to-peer link sharing, like Facebook, Twitter, Mastodon, Fark, Reddit, Slashdot, or even this website).

They're not even removing the ability for the browser to render XML. They're just removing an in-browser formatter for XML (a feature that can be supported by server-side rendering or client-side polyfill).

I see you have done a fair amount of work to document calibration for various scenarios. Have you tried to calibrate to ignore cats? Can you prioritize different algorithms to focus on size rather than speed of movement?

Also, I use an ebay purchased ruckus router designed for commercial settings. Will the stronger signal and beam forming from the router provide better or worse performance, or is that mainly down to the esp32?

At work at the time (I was an intern), in 1993, we ran SCO Unix on a 25 MHz 386sx with 8 MB and another 6 MB on an add-in card on the ISA bus. And while the compilation with Motif was a bear (1 hour for a 1 MB executable), the actual app was reasonably snappy.

I can't imagine how FAST that system would feel with modern hardware.

Historically, information sources with bias have succeeded. Readers Digest is famous for projecting a specific world view, and it lasted many decades.

So much though I want to run with "the truth will make you free" I suspect the size of the chequebook behind this means we're all going to confront Grokpedia as a source of "trusted information" for some considerable time.

I look forward to interesting messages outside of the white supremacist emerging, like weird science takes on genetics, proofs of god, assertions which are demonstrably false to their inputs but persist, doctered photos.

God forbid that there is a significant launch failure on Musk's Mars push but when it comes, Grokpedia will be the last place I look for data on root cause analysis.

> We are nice to people because cooperative societies out performed the non-cooperative ones on the macro level

I.e. biology gets what it wants... We want to survive, mother nature wants us to survive, society wants to survive.

I am absolutely not suggesting that outright jerkish behaviour is acceptable (although to suggest jerks have no social success is probably untrue; plenty of people who are attracted to jerks). I am arguing that if there was no personal advantage whatsoever to being social and nice to people, we wouldn't do it. We'd be lone animals, spread out across the land rather than concentrated in towns and cities. There's a spectrum of selfish behaviour, right? We are somewhere in the middle because it's advantageous to be.

What I don't understand is the pretense of defending Trump at all. I mean, it's clear that even if you watched Trump assault a 13 year old with your own eyes, it wouldn't impact your support for him. Why pretend that there is some moral divide between Bill Clinton and Donald Trump in this when you can just say "I support Donald Trump no matter what, and despite Bill Clinton no matter what"?

Personally I've never been shocked that some of the most powerful people in the world like to go to a private sex-island where they could do as they pleased. That's precisely the incentive to becoming so incredibly powerful in the first place: to be able to pursue personal gain with increasingly less consequences.

openreview (https://openreview.net/forum?id=Wjgq9ISdP0)

I found this paper both really interesting and clear. No one part is very novel, but It composes disparate threads to obtain what looks like strong results in OOD length generalization. Even for the toy task, and using a DSL (vs. being an LM), length-generalizing on simple math >4x is impressive, from what I've read.

This also fits my priors for the key elements of unlocking better OOD compositional generalization: variable recurrence, step-wise curriculum training to build depth-invariant algorithms, discrete bottlenecks. Finally, it's very interesting to compare this to the below recent article arguing for the benefits of continuous latent spaces: Reasoning by Superposition: A Theoretical Perspective on Chain of Continuous Thought (https://arxiv.org/abs/2505.12514)

My take is both papers are right, and that continuous spaces are more expressive and can handle tougher problem spaces (e.g. shortest graph path), whereas discrete spaces will provide a better inductive bias for elegant algorithms that can scale OOD. And I bet the two can be combined / balanced.

> How fast is Ruby, lately?

I did recent testing that showed it to be faster than Python but slower than Lua: Lua, Ruby and Python ran my benchmark in 12, 18 and 25 seconds respectively.

This was measured using the latest versions of each language (5.4, 3.4 and 3.13), using only the interpreters, no JITs.

> I haven't used it in about 10 years

It looks like the relative performance of the three languages hasn't changed much since I did a similar benchmark with Ruby 2.0, about that long ago.

As a veteran of the pharma industry, I've studied some old school medications from the Soviet era. Many are still available from eastern European countries. It's fascinating reading to see the "non-Western" (and far cheaper) approaches. Some probably work in significant performance-enhancing ways, judging from the occasional Olympic athlete disqualification that pops up in the news

The problem with QUIC for these kinds of problems is that it is really multiple protocols stacked in a trenchcoat with no way to get at the individual layers.

QUIC has a connection setup protocol, a stream reconstruction protocol, a stream management protocol, a adaptive channel parameter discovery protocol, a resend protocol, a channel bandwidth distribution protocol, and probably a few more that I can not think of off the top of my head just for normal stream oriented transport.

What you really want in this sort of use case is most things except adaptive channel parameter discovery (i.e. half of congestion control). You should already know the expected channel bandwidth and latency and can instead adapt in-context rather than using totally generic mechanisms designed under the assumption of a “uniform/static” network.

Reminded me of Teenage Engineering's Pocket Operators:

https://teenage.engineering/store/pocket-operators

I have a few of those, and heaps of my friends gat sucked deeply into playing with them at the expense of whatever they actually came over for. "Nah, I'm not hungry. You should all eat without me, I'll just finish tweaking this groove."

They're aimed (as the company name hints) as a little older than 3 year olds.

One hint for the OP, it's so cool how you can plug those toys into each other in a chain, and have them all sync - so the percussion, base, and melody can all be programmed on threee different POs, and automatically play together.

That's already being done at some scale to consumers but the actual monumental shift can happen if it can be done to everybody. People are leaving a lot of money on the table by not gauging the prices for individuals that can pay much much more. If Musk is thirsty and forgot to bring his bottle, it should be possible to sell him a billion dollar bottle of water. Anyone around him can just coordinate and gauge the price to the limit and share the profit. The profits from such a trade will greatly exceed the pay of any PA etc, if the opportunity arises just resign don't give him the water for the optimal deal.

It's not semantics, it's your entire point:

> A merchant a) physically moves wheat to where it’s scarce (and valued more), b) physically moves beans to where it’s scarce (and valued more), c) figures out an exchange rate, and d) takes on risks of spoilage and banditry. For her efforts, the merchant takes a fractional cut.

This is not a middle man, this is logistics! An entire segment of the global economy, and not a small one!

> Ten people want to build a bridge. But they face problems: Who works on the foundation vs. the supports? How do we prevent the left side team from building something incompatible with the right side team? When is the foundation strong enough to start building on top? How do we know if we’re on track or behind schedule?

This is project management, also not a middle man!

Like I get nobody likes being criticized but dude, your entire post is resting on a bad foundation. If you start off an article about cars talking about how jetskis are the future of highway transportation, I'm not gonna take that seriously either, because you fumbled it on the starting line.

I've always hated it when people juggle me and when I notice that I'm getting played. "Normal" people seem to absorb this strategy subconsciously throughout their lives and train themselves to do it too because they notice that it works better. To someone who notices this consciously it seems psychotic because well of course it's always easier to cheat, lie and fake your way to an advantage. You should be choosing not to live this way on purpose. I don't think that the person in the article did it from a bad heart which usually makes all the difference but tons and tons of people do it purely for self gain with no regard for the people getting exploited. Here it was his job to do this and arguably it was for the other person's benefit too to get better service so it was not bad. But we should still be able to name it what it is. This tier of strategy is polluting non-work social environments too. The last thing we need is more people who are getting better at faking being interested or caring.

I'm aware that if such people stop fake caring then they will stop caring altogether. Well good, stop gaming yourself to life advantages please that you shouldn't have. Of course it's harder to actually care about things compared to fake caring. It's harder to be an actually good person vs faking being good and it's probably far less rewarding for most to only be getting what they should be getting in life. Luckily most people are not that good at being fake because like you said, it still takes effort. But people who do it all their life no longer feel that effort and this is how you end up with lifelong fake people.

In general we will never get people to stop faking and lying their way to advantages in life so what decent people are left with is to develop an even harder armor that fake people can't get through with these strategies. It's sad but that's what life seems to be: You have to find people who aren't just here play and beat you like you're a videogame or for a darker analogy play you like you are an asset and they are a CIA agent.

In case anyone else is wondering about practical ways to reproduce these effects, I did some quick searching:

Most chocolate / cocoa products are processed in a way that destroys 80%-90% of the flavanols. You either have to buy specialized high flavanol cocoa powder (what the study used), or you would have to be consuming multiple cups of matcha tea, or squares of dark chocolate ever day. You'd likely also want to add high flavanol foods like blueberries, blackberries, and cherries to your daily diet.

As someone who spends a lot of time sitting, and also has a family history of heart issues, it sounds promising. I'm planning to give it a try.

>For example, if you ask ChatGPT’s Agent to book a travel, it’ll open Chromium on Linux in an Azure container, search the query, visit different websites, navigate each page and book a flight ticket using your saved credentials. An AI Agent tries to mimic a human, and it can perform tasks on your behalf while you sit back and relax.

Big tech has repeatedly shown that they are not good stewards of end users' privacy and agency. You'd have to have been born yesterday to believe they'd build AI systems that truly serve the user's best interests like this.

Have they considered nushell though? It works on both POSIX-like OSes and Windows so it's not platform specific. I'd like to know if it wasn't ready in time (then why not work together instead of starting a new shell, pun not intended) or if there are some technical reasons.

I don't see a single mention of nushell in their readme or mdBook which is a shame.

> purist inventors of nixpkgs structured the policy of what must go into nixpkgs to have this rule

No. Both lib.licenses.unfree and lib.licenses.unfreeRedistributable are accepted into Nixpkgs, but the former marker indicates that the developer has declared it illegal to distribute builds so the official binary cache (sorry, “substituter”) does not.

What Homebrew likely does is fetch the upstream binaries from the upstream download server. Nixpkgs does have a policy against that when buildable source code is available, but that’s mostly because the way Nix achieves isolation (both from the host system and between packages) is by placing almost all shared libraries and data files in hash-decorated places that are emphatically different from what an upstream binary expects. On Linux, it’s possible, if very distasteful, to cram that peg into this hole using mount namespaces and bind mounts (see buildFHSEnv et al.); not sure about Darwin, but the general response to asking Nixpkgs maintainers to keep this sort of fragile mess working is, indeed, pretty much exactly “ain’t nobody got time for that”.

I have 3. I have never regretted a single cent of what I paid. I don't get them out and play often, but even the fun I had when they were new was 10 times better value in the dollars per hour of fun measurement that most other things.

(If you happen to be in Sydney Australia, reach out, I'd happily lend you mine for a few weeks if you want to try them and see if the novelty wears off too quickly to spend the money yourself.)

For me very few movies are interesting. They've become expensive soap operas.

Visionary directors like the cohen brothers, spielberg, scorsese, and the writers of that era have just given way to blandness it seems.

10,20 years ago you had the Matrix and Forrest Gump.

Today you have, for example, Jay Kelly and Die My Dear. Well produced soap operas. These movies are literally just...a run of the mill story.

And Im not cherry picking.

Vanishingly small number of movies today seem to have a unique vision or be compelling..at least to me.

They even managed to turn Star Wars from a space opera into a space soap opera.

I don't want this feature. I have LaTeX documents on my computer containing my personal thoughts. Some of them I want to keep to myself. And some of them contain my own ideas that I find embarrassing. I don't want to hand those documents over to Microsoft servers, nor do I want them used for AI training. I want them to know that these deeply personal thoughts are mine.

I think this depends a lot on the region. I find that forecast quality differs widely from region to region. My guess is that it's a matter of (1) some regions have less advanced models available to them and (2) some regions have fundamentally more complex and unpredictable weather patterns.

Concrete if anecdotal example: weather forecast in SF are fairly accurate but the weather patterns are also simple to predict with the Pacific High and the simpler high level mechanics at play. Weather forecasts in Seoul are quite often completely wrong, but the weather patterns are also much more dynamics at a macro level with competing large systems in China/Gobi desert and the Western Pacific.

I'm not a meteorologist, just a sailor who likes to look at weather.
