Debian dash is a minimal POSIX shell that also is able to implement "set -o vi" (as suggested by POSIX.2).

http://gondor.apana.org.au/~herbert/dash/

The dash shell doesn't use GNU Readline to implement "set -o vi" but instead uses "libedit":

https://thrysoee.dk/editline/

Debian does not appear to link dash with libedit, so command line editing is disabled.

They should consider doing so, and offering dash as an interactive shell. This would give people fewer bashisms to unlearn when they need to write portable scripts for the POSIX shell.

The dash shell is actually reasonably pleasant for interactive use when compiled with libedit.
This is an interesting article, but as a Swift language designer, I'd really appreciate it if people didn't randomly throw out wildly inaccurate information like "Basically everything in swift is an Arc<Mutex<T>>".
I get prototypes for features [0].

For me, the sweet spot is simple but time consuming tasks where the execution is very clear, or the result is very clear but I have to first read a ton of d3.js docs before implementing it. This stuff LLMs do faster than me typing it. Anything more involved where I myself don't know the final result yet, it's faster to figure out the problem while coding instead of trying to figure it out by describing to an LLM.

That truly sucks for your friend. But the phrasing isn't inaccurate, and the source of their trauma is probably that they were responsible for operating the machine that killed someone regardless of their intent or caution, and not the phrasing of around it. They are well aware that they, as a driver, killed someone.

Traffic safety advocates have fought hard for reporters to avoid the passive voice, or using phrasing that avoids the involvement of the driver. Too many people were reported as 'having died in a traffic accident' or have been 'hit by a car'.

It probably bothers the family and friends of dead pedestrians when reckless drivers are reported to have been in an 'accident', or that their car killed someone and not the driver.
The cognitive dissonance involved to say that nuclear needs public subsidies to pay for themselves when wind and solar need the same is pretty wild. And again - wind and solar, with all those subsidies, continues to fail to displace fossil fuels in the grid because the costs continue to ignore the batteries required to supplant baseload (or argue that baseload is an archaic concept with the alternative being a completely different grid which would require a massive replacement). By comparison, France which went all nuclear in the 60s is completely off fossil fuels for their grid whereas companies that continue to go the renewables-only approach continue to see fossil fuel usage continue to grow even if the percentages remain flat.
I live in downtown Dallas and run nearly every day, typically leaving my house at 5 AM, usually for one to four hours. My own observations of the situation from the point of view of a frequent pedestrian:

- Construction has gone haywire. The Dallas Observer has had a running series of articles entitled "Dallas hates pedestrians" for years now because of the number of sidewalks that are chronically closed or simply never existed in the first place. Crews make no effort to create pedestrian corridors and pedestrians are forced into the streets because of it. Sidewalks remain closed for weeks and even months after the work is done. Signs block the sidewalks effectively forever because the crews don't bother to remove them even when work is done.

- Drivers absolutely do not give a shit and pay no attention to pedestrians. I stare these people in the face as I'm approaching on a sidewalk and they do not see me because they're not looking. They only look for oncoming vehicle traffic, not pedestrians. Frankly, I'm probably going to get hit at some point. I've been within inches several times in the past year even when I had the clear right of way crossing in a crosswalk on a green light.

- Highway offramps are in terrible places. Vehicles are being asked to go from highway speeds to downtown speeds in the span of a few hundred meters and they don't because they'd have to be slamming on their brakes to do it. I intentionally avoid roads that are near the highways because of this. Drivers there will be flying off the highway and it won't make any difference if they see you or not.

- Dallas (and presumably a lot of other US cities) has a huge problem with chronically homeless people living in the downtown area. These aren't the "can't afford housing" uptick in homelessness people. These are the randomly wandering into the streets at all hours of the day and night screaming at ghosts because they are clearly severely mentally ill and have been homeless for years if not decades because of it. Little to no services exist to do anything for these people, and as encampments get shut down, unless they're just going to die, they don't really have any choice but to take to the more trafficked streets.

- Presumably because of increased reliance on mobile phone map apps giving directions, increasingly many drivers clearly don't know the area and get lost and confused very easily, often going the wrong way down a one-way street or frequently stopping and starting because they don't know if they're at an intersection they're looking for or if it's the next one. People seem to be increasingly driving through neighborhoods they are not familiar with, including neighborhoods that previously saw virtually no vehicle traffic except for people who actually live there. In addition to apps trying to route you around congestion, this is probably also a symptom of the fact that so much housing has become short-term rentals and even the people occupying housing in the neighborhood don't actually live there or know the neighborhood.
Go read the science a bit better maybe. Nobody's predicting the extinction of humanity or even sophisticated civilization through human-caused climate change in the next century or any remotely prediction-tolerant time span. This kind of nihilistic fatalism is not only disconnected from any scientific evidence or plausible scenarios, it also pushes away anyone on the fence for an assortment of reasons.
Second this, because I'm no mathematician myself and it doesn't look like there are much layman-available material out there. "Point-free" is also another name for tacit programming (i. e. without assigning names to variables, like Forth or bash pipelines), but I can't find any reference on if it is just named for superficial similarity or is there some deeper theoretical connection between point-free topology and point-free programming.

I mostly agree with you, but there's something to be said for keeping the poverty away from city centres, which is some of the most economically productive land per unit area. American poverty seems to congregate in cities, presumably because the cities can afford it, but that seems precisely the wrong perspective.

Even if there is some sort of difference, all it does is reinforce the impression that you need money to maintain relationships with those in politics.

Then again, if I had gone to Yale or Harvard like most of the SCOTUS justices in the majority, I'd see that as part-and-parcel of existence.

It wasn't luck. There is always space between cars during stop-and-go traffic as cars take time to accelerate.

A skilled driver always makes the smooth transition into those gaps. I know most HNers are goody-rule-followers and can never appreciate the skill required to make that maneuver consistently. But, this is a clear example of separation of intelligence / skill and I'm happy with the bet that these are signals of intelligence

> this is a wild microcosm example of how the web breaks in ways we don't expect.

I think the performance characteristics of the web are subject to change over time, especially to allow increased security and privacy.

https is another example of increased security+privacy at the cost of being slightly slower than non-https connections because of an extra round trip or two to create the connection.

The lesson I take from it is: don't use complicated optimization techniques that might get out of date over time. Keep it simple instead of chasing every last bit of theoretical performance.

For example, there used to be a good practice of using "Domain Sharding" to allow browsers to download more files in parallel, but was made obsolete with HTTP/2, and domain sharding now has a net negative effect, especially with https.

https://developer.mozilla.org/en-US/docs/Glossary/Domain_sha...

Now they're realizing that HTTP/2's multiplexing of a single TCP connection can have negative effects on wireless connections, so they're working on HTTP/3 to solve that.

Also don't use polyfills. If your supported browsers don't support the feature then don't use the feature, or implement the fallback yourself. Use the features that are actually available to you.

> to an American eye, barbed wire on top of a wall codes as "this neighborhood is unsafe". To a South African it codes as "this home is protected and safe" -- very different reactions

If the neighborhood is safe, the barbed wire would be unnecessary to make the home protected and safe. Not really sure why the distinction is necessary. In your South African's take, what happens when you leave the protected and safe property. To me that means you are stepping into an unsafe neighborhood.

If the model can reflect the existing documentation that well, w.r.t. changes in code, you may as well use the LLM as the documentation by fine tuning it with boilerplate/initial docs and have it generate the future documentation based on a context of just the code.

My attempts at this (DDD) involve choosing system components or protocol/API layer dependencies such that they can generate the documentation when they generate the client-lib and server interface code. Isn't always possible, and doesn't cover everything. Having a comment-doc pipeline also helps but sometimes that just adds more trees to occlude the forest. This way the documentation doesn't lead the code too much (I'd rather see deprecated warnings than Not Yet Implemented errors).

Good team communication and a solid codelab for new members can go a really long way, too.
I suspect radar like this needs only a tiny time slices to do its work. Say for example that it's only necessary to get updates about the moving object 100 times per second: every 10 ms. The radar pulse durations necessary to do the job can probably be measured in microseconds, though. A 10 ms separation between pulses measured in microseconds is a large amount of empty space.
I honestly don't understand pretending that there was any value in this project. The founders have a history of grifting, and the product itself betrays the advertising and the software itself appears held together with shoestrings and bubblegum.

As the founders beg for a buyout even as the product has completely failed, it can't be any more clear that this was a get-rich-quick scheme by the founders, and never a serious venture.

"Experimenting with form factors" is a cop-out for what they actually did.

"I feel uneasy about design patterns. On the one hand, my university class on design patterns revived my interest in programming. On the other hand, I find most patterns in the Gang of Four book to be irrelevant to my daily work; they solve problems that a choice of programming language or paradigm creates."

My relationship with design patterns changed when I stopped viewing them as prescriptive and started viewing them as descriptive.

This is what you said:

> An archive very clearly means something very specific

What you perhaps meant to say was:

"An archive that infringes US copyright laws should not be afforded protections under US law"

Most people, myself included, took issue with the way you dismissed IA as not being an archive altogether; it clearly is an archive and whether or not it infringes US copyright law does not change that fact.

Whether it should be protected by law is a different matter.

async/await is just syntax. There's nothing saying that two async calls can't run fully in parallel. "Blocking" is subjective too; in a way even JS is doing some parallelism.
Honestly that was one of my first thoughts when I saw this, someone is going to draw one of those. People love trying to be offensive in something that barely allows communication. I remember seeing some MMORPG that had no chat where players would log in and just stand in the shape of a swastika.

I think the following is a valid question. At least I hope it isn’t completely stupid.

So much frustration here :-/
My take is that there is no such thing. This is not because there aren't tools now that do "similar things" to what HyperCard did, but there is simply no longer a personal computing environment in which such a tool fits so instrumentally and seamlessly.

HyperCard came about in an era where personal computer users were still being inculcated into what using a computer even meant. That was the moment to let end-user programming and malleable systems like HyperCard take over. (A somewhat similar thing might be said of OpenDoc, but that's a bit different)

From a corporate perspective, what even was HyperCard? A way computer users could just make their own basic applications? How do you continuously make money? What about your computer's dev community? Because of these and other commercial concerns, both the way users today engage with personal computing _and_ the tools we have to manipulate our computing environments are strongly determined by a consumption model -- and there exists a strong bifurcation between users and programmers.

We have no true HyperCard equivalent today because personal computing went in a different direction.
What do you propose to measure it more accurately?

In the tacit programming case, I'm pretty sure it's for (a) superficial resemblance, and (b) the excuse to call one's favoured technique "pointless programming".

(there's probably something interesting to be gotten at by considering how much violence a particular function does to structure in the input space —thinking of compositions of homomorphisms being homomorphisms of compositions, or how mapping a monotonic function over keys allows one to avoid reindexing— but I'm pretty sure that's mostly orthogonal to whether one binds parameter names or not)

You have to incorporate county and state debt per taxpayer if you are comparing a locale in different governments.

Connecticut has a very high (multiple standard deviation above the norm) retiree benefit debt, due to decades of underfunding. But these numbers are not easily comparable because there are no strict rules around how taxpayer funded DB and retiree healthcare debt is calculated.

It just shows up as a bigger and bigger proportion of government expenses.
Between the Autopian, Defector, 404Media, and about a dozen other sites, it's fascinating how much good writing, interesting content, and genuinely great internet was apparently being held back by whatever combination of VC, private equity, and just general herb-ish "media executives" over the last decade.
