GCs have not come far enough if you care about performance.

A modern "fast" GC has latencies similar to disk I/O on modern storage. We don't make a habit of randomly dropping a blocking disk I/O in the middle of a performance critical path, and disk I/O is less likely to pollute your CPU cache as a side effect than a GC. Given that performance-optimized code is routinely designed to eliminate the overhead of even context switches (e.g. thread-per-core architectures) to great benefit and GC pauses are much more expensive than a context switch even when "fast", it is difficult to develop a theory of how a GC does not have an adverse impact on performance.

You could try to make the argument that most people writing Rust don't care about performance so it doesn't matter, but that is likely to be controversial at the least.
I don't believe only turing machines are capable of executing other turing machines... Surely lambda calculus can do the same? I was under the impression, lambda calculus can indeed execute itself with even less code than turing machines

There's several very dubious claims that are stated way too confidently like this in the article, like "Yep, virus scanners are almost completely useless"
Right, definitely wouldn't want that. But do we just have to accept the negative impact the internet can have on children as a necessary evil then?
If the business/utility/people who bought the smart meters did not specify a port where they can be read by wire (and therefore a new wireless module can be installed) then they get what they deserve.

Sure, they could be. The evidence doesn’t bear that out as a primary cause, but it’s possible to the best of my knowledge.

> But in industry, there are no reviewers serving as adversarial gatekeepers. You may present analyses to a skeptical audience, but if they disagreed with your model priors you would work with them to come up with a mutually agreeable model because you're all on the same team.

This experience may not be representative. The web is absolutely filled with anecdotes of gatekeeping and obstructionism within engineering orgs. The phrase "internal politics" comes immediately to mind.

Last week the Android App Store finally approved my GopherGeyser app! It's used to control our sprinkler controller (over MQTT) to turn your outdoor living space into an animal-themed Bellagio water fountain show / splash pad to entertain kids/dogs in the warm months! :)

It's still pretty basic, but I'm pretty proud of it. Even though it doesn't use AI, I used AI to write the app, generate copy, and generate the image assets, as I didn't care to learn Flutter just for this one app and have no artistic ability.

With regard to software, I've long since accepted that HP, Brother, Canon et al can't write drivers to save their lives - and shouldn't have to - in a world where AirPrint, Chrome OS Printing, Windows IPP, or Direct IP printing exist.

It's long past time for printing to be treated as an OS service, where 3rd parties write the smallest possible shim to plug into available devices.
Yeah I'm guessing just replacing the bridge will cost a lot more than the bumpers would have, even without counting the broader impacts.
Are you really nitpicking semantics here?
>a pretty good source of protein.

Unlike many things that are referred to as a "good source of protein," mushrooms have a really great macronutrient profile:

100g of common button mushrooms = 3g protein, 3.3g carb, .3g fat

Compared to Lentils (which are the best of the standard foods labeled as "good source of protein") 100g = 9g protein, 20g carb,.4g fat.

The problem with lentils is that you have to eat a lot of carbs to get protein. The ratios are terrible for most other legumes, soybeans and nuts.
I don't think you can really generalize this attitude. I, for one, want to have a good manager. A good manager makes my work more pleasant and makes me more able to produce quality. Having a manager is not anathema to me, or most of the devs I've worked with, at all.

This essay seems to confuse "engineering manager" with "bad manager". Nobody, in any field, needs a bad manager. A good manager is worth their weight in gold.

You can do subpixel rendering with fixed-point math https://www.copetti.org/writings/consoles/playstation/#tab-5...

I thought the problem was that it only had 12 or 16-bit precision for vertex coords, which is not enough no matter whether you encode it as fixed-point or floating-point. Floats aren't magic.

Yes, the lambda calculus can. They are equivalent.

But Turing's machines gave us the model to think that way. In my opinion.
If you don’t live somewhere with famous/major bridges it’s really easy. I doubt I could name ten bridges period that aren’t in my mid-sized city (and I can only give the correct name for two of the ones here, neither of which is famous). I can only identify maybe four by sight from outside my city—I can name a few that I couldn’t pick out of a lineup of photos.
Just for fun, I'm writing an internet forum software from scratch, strongly inspired by phpBB and the likes.

It is split into an Angular UI, C# ASP.NET Core RESTful API and postgres database.
I aimed to let EF Core handle the data model in the database and am pleasantly surprised by how well it works.
Also updating the database is a breeze with its migrations.

The features of a forum seem easy enough, but I find it difficult to detail it out into the data model at times.

Laid off last fall, and while looking for a new role I've been working on an old idea I had for a MIDI sequencing app. It's meant for live electronic music production, so it's not a full DAW for composing and editing tracks or anything like that. It just records notes for different MIDI devices/channels and loops them back over a selected number of beats. There are some other features as well, like an arpeggiator, but it's pretty basic so far. I've been meaning to record a demo video with real audio, but I'm not actually a musician myself so I haven't come up with anything presentable yet.

I’m working on a nutrition tracking app for iOS called FitBee (https://fitbee.app). There’s been a huge number of “AI” based products in this space but they’ve all been relatively bad in terms of accuracy and reliability (eg the Humane AI pin demo). At some point I’m sure I’ll introduce some AI based features into the product, but for now I’m focused on making it the fastest and most convenient way of tracking your nutrition.
Hope it's okay that I just reply to everyone

Wiggling is down to lack of precision and lack of subpixel rendering, unrelated to Z buffering. Z buffers are for hidden surface removal, if you see wiggling on a single triangle floating in a void, it's not a Z buffer problem.

When you see models clipping through themselves because the triangles can't hide each other, that's the lack of Z buffer.
It sounds like a very difficult social challenge though.
> When did having a website become something exclusively for old people?

It's more that having a website never became a thing for many businesses in the first place. 30 years ago they might have had a listing in the phone book. Nowadays that kind of business might have a facebook page, or more recently an instagram account. Creating a website (even with something like wix) requires a level of skill and effort above that.
Much has been made of Shanahan's Silicon Valley connections, but interestingly she's barely been mentioned on HN or by TechCrunch. Despite that, she does seem like the most stereotypically Silicon Valley person ever:

At this point in the journey, they were cleared of the docks but not the channel. There wouldn't be a docking pilot on board nor would there be any tugs. It was cleared and under it's own propulsion until it wasn't.

My sailors guess from the footage and the reports is diesel generator failure(s) resulting in loss of power, restoration of power, then loss of power again. Bypassing the diesel generator (which provides power to hydraulics too) and manually throwing the engines in reverse. The billow of black smoke. This could have possibly burned out an engine, blowing the camshaft or propshaft or transmission.

The reverse was too late as the ship was already heading for the bridge pylon. Even at full reverse, you couldn't slow it down fast enough. Tragic.
So, to gather anecdata, a question to you: do you wear corrective lenses or contacts in your day-to-day life?

I never said I couldn't tell the difference between my corrected vision and the vision pro. But it's probably close to as clear as my uncorrected vision, which is how I experience life the majority of time. In a very real way, it is lifelike. My reaction to the cover coming off is "oh, I don't have my glasses on" not "oh, I'm looking at a screen". In no world would I have the same reaction to the passthrough on any other VR headset I own.

The latency, lack of screen door, minimization of warping artifacts, and yes, even the resolution, are at a place where someone who doesn't have the privilege of 24/7 perfect vision could easily mistake it at first glance. There's lots of places to improve (mostly the blur when moving your head), but we're at the point where "not literally indistinguishable" is the point of contention.

Also, keep in mind "lifelike" has never even meant "literally undisguisable" in the first place. People have been using it to describe graphics since the PS1, so I think it's fair to use to describe something that looks more like life than the majority of even present-day "realistic" 3D games.
Yes! Part of my disdain for Spotify recently is because they removed lyrics about six years ago and when you clicked the button, it started saying "lyrics will be back soon". Then that button disappeared for like five years...
Anyone know about backup steering power on these vessels? I know they typically keep emergency generators, but does this provide adequate steering power?
I think when nanodevice engineers talk about 2D problems, they are talking about devices in which the interesting physics happen in 2D.

The actual devices actually exist in the 3 spatial dimensions of course, and evolve in the time dimension. They just have physics that involve very flat sheets of things, or all of the interesting stuff happens on the surface of something.

The big deal stuff about time and space both being dimensions is more of a relativity thing I think. IIRC in quantum physics time is really annoying and everybody hates it.
The sheet piling didn't need to be 50 years old.

In 1977 (and in 1972, when construction began), vessels of this size did not exist, and certainly were not allowed in the harbor[1]. But over time, they were given authorization, despite the fact that they could collapse the unprotected bridge like a load of toothpicks.

The real crime here is that there was no retrofit to protect the pylons. It was almost certainly considered and rejected due to cost.

> Minimalism here doesn't mean "not many notes" it means deliberately restricting the range of harmonic and rhythmic materials available to the composer

This is not necessarily what minimalism means. Minimalism is just an abstraction for certain kinds of art, possibly with various incompatible techniques. For some artists (not just musicians, but also painters, poets etc) minimalism means "repetition"-ism i.e. art with excessive amount of repetition to the point that you'd normally expect it to be "boring" but it somehow uses it to its favor with rhythmic, harmonic, or formal techniques. Philip Glass is the pioneer of this idea in music, and I personally consider him one of the most creative and groundbreaking artists ever lived. His music is very tonal, "simple" and repetitive in his oeuvre (i.e. repetition not just in one work, but repetition among his body of works like minimalist painters Mondrian and Rothko) which makes him a very very controversial musician, some critics considering him a charlatan. To me, he's a Schoenbergian figure who is making a bombastic and over-the-top artistic statement by going against the current of his artistic tradition while remaining firmly in it. Similarly, Schoenberg was also considered a charlatan during his life, especially early on.

For those interested, I recommend this composition: https://www.youtube.com/watch?v=TKJoQ8BfQhw
(full on spotify, sorry)

Oh also if you ever think "classical music doesn't have a cultural force anymore" please pay attention to contemporary film music that's not neo-romanticist. You'll see that there is tons of minimalist influence from Glass, Reich, Andriessen, Richter etc...

You should be able to use the app. The Chinese Communist Party should not be able to control the app's content and access all the data that it generates.
How do you imagine that will be enforced? Perhaps by... ID?

Yes. If you hack stuff together, you need much less support than if you try to do engineering.

The role exists for a reason, but the reasons aren't true for every situation, nor is the exact shape of the role the same across teams. These nuances matters very much when you're trying to decide if it should exist or it shouldn't.

The idea is that you have a "framework" that you can change for what you want the music generator to produce. You can download the MIDI files it produces as well.
> Californians, for example, don’t use the plural contraction. You have to say “there’s many options” instead of “there are many options”. Otherwise you sound like a weirdo.

Don't extrapolate too far from a small sample. I don't think anyone would recognize you as a non-Californian just for saying "there are".

Now, if you refer to highways US-101 or I-5 as anything other than "The 101" or "The 5", then you're clearly not from here!

Wikipedia does not back me up on this, however. Apparently the "The" names are SoCal-indicative. This has not been my experience here in NorCal.

FWIW, I learned the meaning of "based" once, but I found the explanation dissatisfying and promptly forgot it. :)

> Everyone being surprised at the bridge collapsing needs to reconcile with the amount of force that struck the bridge ... I am also a bit surprised at how many people don't grasp this or grasp engineering, magnitude of forces and design principles.

A spokesman for CalTrans claimed today that Bay Bridge could have taken the same hit without damage, thanks to fenders that protects all pylons for all bridges in the San Francisco Bay Area (1). Cargo ships are heavy, yes, but it appears we have the technology to prevent bridge collapses due to these sorts of collisions today.

1. "The Bay Bridge’s fenders insulated the span during the 2007 incident, so that the Cosco Busan ship struck a bumper, never hitting the bridge itself, Ney said. He noted that fenders on Bay Area bridges should be able to handle a ship traveling at 8 knots, the velocity at which the ship hit the Francis Scott Key span."

I'm kind of confused how a President can promise something like that. He doesn't have any power to appropriate money, and given his party's lack of control of Congress, I'd argue he can't promise anything.

Not to mention that one can scarcely find a "bluer" area than Baltimore -- I would assume that the most proudly right-wing politicians would be more than happy to let Baltimore suffer to score points with their polarized supporters. I hope it doesn't come to that, but they tried to block Hurricane Sandy relief, despite every hurricane in the South being an automatic 'non-partisan' emergency.

This hit me a a bit ago - you can't really tell how big ships are if you just see pictures of them on sea. I recently hit this in real life. Yeah it's a ship. Oh. It's like 3 - 4 times as tall as I am above water. And it goes 2-3 stories down. And holy hell, a crows nest 30 meters up is... really high up?

And we got the good tour, because we had a severe storm warning as we visited that ship - the kinda storm in which gusts stop you in your tracks and forces you to lean into it to not fall over. Was a great experience. I wouldn't want to be up there with that kinda wind.

And this was a medium sized clipper, somewhat on the small size.

And based off of that, I kind of want to see a retired battleship or an aircraft carrier. Because now I have an idea of how dumbfounded I'll be at those kinda dimensions. It just doesn't appear that big on photos!
