As someone who's been on and off various Mastodon servers for the last 5 years, you're absolutely correct. Geeks building this stuff seem to be completely dismissive of the power of network effects towards Facebook and Twitter's dominance, they would rather pretend it's not real and just keep building inside their little bubble. Social media users just want to talk to their friends and meet cool new people, they don't care about dealing with stupid server/moderator drama which there is an absurd amount of in the fediverse. Any exposure to that at all is a huge anti-feature but it's unavoidable on a decentralized system. People attempting to romanticize the old days of usenet and IRC always seem to mysteriously downplay that part. I don't miss that at all, it was truly truly awful.

I have a lot of respect for the founder of Mastodon but I suspect even he knows this is a losing game in the long term.

A related question: Is there a cheap way of splitting USB-C/Thunderbolt port on most Dell laptops to 2 HDMI outputs without buying an expensive hub?
My threat model while hiking in the forest is not that a pitbull or attack dog pops up and goes for the kill. Every time I’ve seen a dog it has been a big, just curious dog that probably has an owner hiking somewhere nearby and its reassuring to have a big stick just in case I need to appear intimidating.
I don't know any company that would allow these terms in an internally visible recognition.

Certainly not the case at every organisation; unions have a strong presence in some long-established private industries and public sector organisations, including general communications.
oh I have a totally different reaction to that line, and I thought this was where you were going at first.

Which is: Apple is really not a business-user focused company. Windows-based PCs have long dominated the business world. And as someone who does use Macs for both personal use and at work, setting up a work computer is always an awkward, sup-par experience. There are so many features (like iMessage, Facetime, and iCloud) that are exclusively designed for personal use, and no good way to e.g. configure which parts of my personal data should be available on my work computer. Or I can use a totally separate apple id on my work computer, but then I can't get access to things like my Apple Music account that I am subscribed to on my personal account.
My point is that the shell would be a much better tool if the language could be expressed with a simple, LR-parsed yacc grammar.

Because the shell needs such an advanced parser, it shows that the language is full of ambiguity and pitfalls.

The slides for the parent presentation have this gem:

Quiz: Which is the command that outputs \\ ?

1 echo "\\\"

2 echo "\\\\"

3 echo "\\\\\\"

The language should be clearer, and less ambiguous.
Last.fm doesn't allow "untitled", "various artists", "track 01" and other titles that may suggest the song is incorrectly tagged. This leads, of course, to edge cases where an artist has a track named "untitled" and it can't be scrobbled.

Moreover, last.fm also has an issue with unicode characters and some artists/albums may have two or more different profiles. It's a mess!
Would that even work? Using the pretrained model, wouldn’t you then be in the “local” optimum?

Although from a transfer learning perspective, chopping off last layers and retraining… You are prob right
>We closed a remarkable bit of that gap in the 19th and 20th centuries - the gaps remaining are getting really difficult to fill. This is the counterargument to innovation will solve all our problems.

When you combine this with birth rates below replacement level that leads society in the direction where it's a) harder to fill those gaps, and b) much less people to fill them. So, having far less bandwidth available to do that discovery/work seems to be in general a trend people don't seem to acknowledge.
I’d like to chime in to highlight how totally underrated the Blackmagic eGPU series Apple collaborated on was.

They are virtually silent, have capable, reliable TB3 hubs. Outside the Mac Pro line, the BM eGPUs offered graphics capability to macs going back years that was only surpassed with the recent ASi MBPs.

They are remarkably stable and ultimately a great value.
> Do I need a new account for each instance being the main question?

This is a very common question, and no you absolutely do not.

The system works like email - you have interoperability and can pass messages along between servers. You don't need to join both gmail.com and hotmail.com to send a message from your gmail address to a hotmail user.
That was one of the reasons I joined the USAF. Dad was in the 99th ID at the Battle of the Bulge (Purple Heart, Bronze Star) and later crossing the Ludendorff Bridge at Remagen. Granddad was a Sergeant Major in the Cheshire Regiment[1] for His Majesty doing secret stuff he never talked about. I was the underachiever of the family - serving in Germany during the Cold War.[0] But I felt compelled to follow in the family tradition, and I'm glad I did as it helped me get my shit together.

Most of the people I served with had some college. There were a couple of guys in Basic with Bachelor's degrees, and we wondered why they went enlisted instead of officer. But each to their own.

>"As long as you have funding, quantum gravity is basic research at its finest. If not, it’s pretty much useless knowledge"

the issue of the public seeing basic research as useless has always bothered me.
and I'm not sure if basic research is truly useless because of its innate nature or if basic researchers themselves make it look useless on purpose because they like it to be secluded from "real life" or maybe it's too exhausting to try to explain to people while it's still ongoing.

reading Rutherford's own notes and biography was truly enlightening and refreshing, there is more to physics than the purely theoretical part.he didn't think he was too good to work with his hands.

Engineering physics / applied physics / medical physics are all interesting interdisciplinary fields where you can see physics come to life.
DisplayLink is proprietary crap. There are apparently drivers for Mac, Windows, and ChromeOS, and a (open?) driver for the old, outdated 1.0 version. It won't work at all for anything recent.

Despite the similarity in name, it has _nothing_ to do with DisplayPort. AFAICT, does a compressed image thing over USB, like VNC. But proprietary, of course. I was also tricked into buying one by the name and was surprised when it didn't work with Linux.

Linux users should buy something that uses DisplayPort, _not_ DisplayLink. See https://www.dell.com/community/Laptops-General-Read-Only/Dem... for details on how USB/thunderbolt and DisplayPort when together.

From Amazon? What are the odds that they were actually Satechi?
No, at this point they probably can't. It's locked down the way it is to specifically prevent that sort of thing.

It should be removed from enrollment, the IT dept doesn't want that on there any more than OP does.
Always a pleasant surprise to be scrolling through HN and seeing one of my articles on the front page!

For anyone interested in how that code would get zero memory safety overhead without the classic borrow checker, a big part of it is because of the "region borrow checker" [0]. There are some other factors (iso regions, hybrid-generational-memory, etc.) but region borrow checking is the big one.

You could also have a continuously variable gearbox, which is still hugely problematic, but would waste less energy.
>This is the lesson that we already learned in the 1800s with monopolies; they distort reality. It’s useless to argue “if you don’t want to work for them, don’t” because they often pay just better than your local alternatives, but by virtue of their economy bending power, they will exert an insane amount of control and influence until they are either regulated or there is no competition left and I don’t even have the fruit packing warehouse anymore, but the Amazon Oranges Fulfillment Center.

Amazon is nowhere near a monopoly (or monopsony), at least when it comes to employers.

EVs Are Not Close To Being As Cheap As Gas Cars, Mercedes Says
The electric vehicle industry has seen a massive transformation over the last decade, in no small part thanks to massive reductions in the cost of large lithium-ion battery packs.

EVs may not get much cheaper at all over the next few years.

Reaching so-called "Price parity," Schäfer said, just isn't possible with any current commercially available battery technology.

The kind of affordable, high-density batteries required to make it possible either don't exist or only exist in tightly-controlled lab settings.

While we wait for a breakthrough, Schäfer says they can't promise that EVs will get any cheaper in the near term.

While increasing demand for large battery packs has helped through manufacturing advancements and economies of scale, it's this scale that is now posing a large challenge.

Thanks to both the increasing popularity of EVs and continued growth in consumer electronics, the demand for lithium batteries is on pace to far outstrip the capacity of current rare-earth metal mines.
Funny - same thing happened to me late night at the train station in Chicago.

And it still costs as much as a computer.
Nim feels like it would be a great option for interoperability with the existing ecosystem of OSes, LwIP, USB stacks, etc.

OTOH, my experience of those libraries has been decidedly mixed, with it being relatively easy to get things apparently-working only to later sink dozens of hours into debugging that occasional weird crash.
>I think we are plenty as is, and as for why bother to make the universe do our bidding - because there's great pleasure satisfaction and fulfillment in bending cold indifferent nature to our will...

We're starting to wake up to the reality that all we're really doing is bending it out of shape and when we push it beyond the yield strength it will snap.
with a very unappealing name… sorry.
That's the first time I heard about someone rejecting the theoretical basis of compilers on a conspiratorial basis, are you sure that person was rejecting your suggestions out of literally disbelieving in the theory, and not, for example, doing it from the "this 10-line regex is better than any fancy parsing technique out there" angle?

It just seems weird to me for somebody to know what a "compiler" is yet refuse to believe the fundamentals. Compilers are pretty niche, there is no glory or mainstream pop science around them.
>But you essentially can't overcome the network effects. There's no way to gradually build a social network when everyone is already on a different one.

How did Facebook overtake Myspace then?

I'm not really convinced that the thing holding back Mastodon and other efforts like it is merely incumbency inertia. I think even if you started from zero again, Twitter would take off and Mastodon wouldn't. The Mastodon experience does not strike me as better than the Twitter experience for most users. Most people don't really care if if something is open-source or federated/decentralized. Those are not features that draw users.
What are your favorite Go books?
You can create custom build configurations to set the optimizations and add debug info. Or just add instrumentation code (print debugging) which is more useful for debugging heavy numerical stuff most of the time anyway.

Running anything through valgrind or cachegrind will have several orders of magnitude slowdown - that's inherent to how the tools work.

To your last point, just add -g to your compile flags and see how far you get.
The only problem with this dualism is that it really isn't so.

The way mathematics is developed is the same way it should be learned and applied. Your geometry class today does not start with Euclid's axioms, but instead by developing intuition for concepts in the simplest way possible (2D plane, 1D lines), playing around with them, and then formalizing them (which means defining them rigorously to the very last detail, to ensure eg. your concept of a straight line is always a straight line), and generalizing what you learned about them (stating it as theorems). The same is with numbers: I've yet to hear of people starting their arithmetic training with Peano's axioms, yet it's common to teach numbers by pointing at one object and moving another one next to it, and claiming that's now a "two"; adding another one to that gives you a "three" (successor() function, right?).

Sure, most primary education skips this playing around with concepts, and fails to demonstrate failings of not being precise enough, but they are all trivial to demonstrate.

But all of those are what is exactly used in formal/pure math development, and exactly the same processes are used when applying mathematical insights anywhere else. There is no difference at all!

The level of rote memorization and combinatorial explosion rises as you go into more advanced math with more abstract concepts to deal with (which is what I think people really struggle with, since it's a different language, and then intelligence does come into play as well as you start dealing with bigger complexity), but I like to say that math is the simplest form of expression of the human brain, but no simpler. It has well-defined boundaries of our comprehension too (we need to assume some things are true without proving them, aka axioms and base terms).

The biggest problem of all math instruction today is that it's mostly performed by those not understanding the simplicity of it, and thus the only thing they can do is transfer their misunderstanding on to their students. This includes parents who teach their kids basic concepts like basic geometric shapes or numbers.

Another big problem is that people simply fail to realize how much of rote memorization is required for understanding mathematics. Being a different language, you have to learn all the "new" words and grammar to be able to effectively apply it, and people usually discount that as not important, and how only understanding mathematics is hard because of the abstract nature.
Look at the first box being lifted and dropped… the box rotates in what appears to be 3D space.

I’m not certain as the rest of the shot looks like really nice 2D parallax, so this could just be really good 2D animation.
Micropython is actually great on ESP32 despite having GC and unless heavy number crunching / camera stuff happening, it feels to be the a really good tool for the job.
I'm honored.
It definitely seems like they do: https://docs.joinmastodon.org/user/posting/
It's increasingly popular in the UK too, though most people still just use Facebook.
That just seems like poor discipline.

But not like creating a typesetting system to use to write your book.

It seems like it is shaping up to a pretty nice language. But writing the compiler in itself is very 20th-century. Just add a parser to LLVM or Gcc and call it good.

But don't make the mistake C, C++, and Rust did, using a prefix dereference operator. Pascal got that one right.

BTW: "get" in a pure function name is code smell. More generally, transitive verbs in pure function names are code smell.
AMD is joining Intel in having Thunderbolt4/usb4 ports on their upcoming mobile chips. Would be great to have an io up alterntive part that has 4, 5, 6 or more ports.
Credibility isn't a thing that opinions have, is it? We each choose how to define "disaster" for ourselves.

But you seem to be ignoring the (alleged) facts supporting the opinion.

It's being reported that Trump never sent another "truth" after a short introductory one quite a while ago.

Either that's true or it isn't. If it's false, then how hard can it be to find proof?

The reporting gives them credibility, which of course could be rebutted by showing they falsified it.
Wind turbines have frequency converters. They are semiconductor devices. In one 3 MW turbine I visited, it was at the base of the tower.

The blade angle is adjusted to get optimum power extraction. Rotor RPM is completely independent of produced power frequency.

> "DC power is significantly more energy efficient than AC power." -> the examples go on to specify end points for electrical energy but we already use DC there, AC is mainly used in transmission, so the claimed advantages of DC are irrelevant.

DC is more efficient for transmission too.

The reason the grid uses AC is that high voltage is always[1] more efficient for transmission than low voltage--regardless of whether you're talking about AC or DC--and in 1900 the only way to step voltages up or down was to use transformers, and transformers require AC. That's unfortunate because for a given voltage, it's more efficient to transmit it as DC than AC.

But today we have power electronics which can step DC voltages up or down, which means we are free to convert the grid to DC.

[1] The single exception is superconducting cables which can transmit low voltage power just as efficiently as high voltage power. But they are not yet cheap enough to be practical except over short distances.
That's too bad. Until these kinds of things are tried, we won't know if they work. And they'll continue to be used as a eternally fake promise by politicians.
Yes, on OOP, once I got into a big battle: We had developed an OOP repository (cache, scoreboard, etc.), then along came CMIS/CMIP, and I was asked to modify our repository to handle CMIS/CMIP.

So, off I went, got copies of as many of the CMIS/CMIP documents as I could, read and studied, learned about the registration hierarchy, etc. Finally I concluded the CMIS/CMIP OOP was just for data definitions and was not programming at all. E.g., a CMIS/CMIP object could not do even 1 + 2 = 3, if-then-else, read, write, do while, etc. So, just for storing CMIS/CMIP data, and data is all it was about, the repository we had was already up to the task.

So, CMIS/CMIP was OOP only in the sense of inheriting definitions of data. So could define an object for a computer, i.e., list all the data were going to keep on a computer, and then inherit (borrow, copy) from that definition to define a laptop computer.

You're right. Chinese products do have questionable reputation.

> Not so much for the Germans or the Swiss.

Since the Germans are known for cars, let's talk cars.

I drive a W212 Mercedes-Benz E250 CDI which I bought new a few years ago. My impression of German products is forever tainted.

It's lovely to drive when everything works, but everything doesn't always work.

It's designed in a complicated way that things are prone to failure, and when it does fail you'll have to take apart the whole car to fix it thereby increasing the labour cost to work on it.

It's been a money pit.

The ride and handling is pretty good though if ignore the weird suspension noises.

-----------

Now, I don't own VWs myself, but you should look into transmission problems with their DSG dual-clutch transmission. Just Google "DSG mechatronic failure".

It's a lovely gearbox, but it's guaranteed to fail at some point. And VW knows it. Yet they still continue to fit it in VW and Skoda cars (amongst others). The rest of the car is relatively fine though. Skoda especially makes superb products (pun intended) — too bad they don't sell in USA.

I hope you still remember the whole dieselgate scam of European car manufacturers.

You might want to rethink your perception of German engineering.

(Note that this is not a reflection of German people or anything. The few Germans that I personally know, and the many more that I've interacted with indirectly are wonderful people.)

Some people don't really have a choice; that extra dollar each hour might mean housing or food security. And, say, a parent in a household might think that's the trade off they have to make: they're horrifyingly miserable, but their spouse and kids get to be better off.

But that's a trade off no one should have to make: it's messed up that we as a society allow this state of affairs to exist in the first place.

And yet here I am, not canceling my Prime membership, because I suck. But hell, if Prime cost 2x what it currently does, and that got the workers involved good working conditions, I would still pay it. Not sure how many people would, though.
If the supply of houses were not artificially constrained, their price would not go up like crazy, and Blackrock would simply not invest. They don't like to invest in things that don't appreciate in value. The fact that their buying drives the price up could be superficially perceived as a win-win for them. In reality, whenever someone is large enough so that their buying of a thing drives up the price of said thing, a roundtrip (first buy, then sell) generally leaves them poorer overall.
I think the real issue here is with the training speed. Presumably a GPU is required to run the game, but is it restricted to just NVIDIA GPUs/a subset of those?

I don’t know of any such libraries offhand and my guess would be that’s because the size of the library generally matters less if there’s a requirement to have a powerful GPU.
