I haven't built anything in Electron, but I've been writing Qt/QML cross-platform (focus on desktop) apps for a few years and I've found it to be a very productive and fast framework. You could easily write the entire app in JavaScript and QML and never touch C++ if you want.

Not sure it's overfitting if this what exactly what I hypothesized would happen when Tesla started cutting prices aggressively. I'm sure I wasn't the only person to see this as their strategy.

Enjoy the Civic — I bought one new when they were revamped in 2006. Loved that thing (and the 40 MPG highway that it delivered, even back then)!
IME there's usually a paid option where demand for parking exists where there are no/few free options.

Your complaint is usually implicitly about a lack of free parking. Folks who insist on bringing their cars to town for dinner can foot the storage bill at a lot/garage down the street IMHO.
A land value tax is one way to achieve that goal with its own tradeoffs. Building more housing close to the jobs is an independent problem with an independent goal.
Merely eliminating a lot of the black heat sinks (i.e. parking lots) and replacing them with native grasses would do a lot to help keep city temperatures a touch more reasonable.

Asphalt both absorbs and radiates heat like mad.
Macros achieve a limited version of a fexpr with much more complicated semantics. Hygienic macros take that a step further - you get implicit renaming of variables which is generally convenient - in exchange for even more complicated semantics.

The abstraction leaks as well. `(reduce and (list #t #t #f))` is probably an error. Calling a macro and calling a function looks the same and sometimes is the same and sometimes falls over.

Macros are sacrosanct to lisp. Hygienic macros are a crown jewel of scheme. They're still the wrong thing though.

In the beginning there was dynamic scope, possibly by accident. There were also fexpr - pass the unevaluated data and the environment, instead of passing evaluated data, which were also dynamically scoped. Sometimes called nlambda. That was difficult to program with and very difficult to compile.

Macros are easier to use than dynamically scoped fexpr. They're much easier to compile and lisp was getting a bit of a kicking for being too slow. There were some papers written, macros were the better choice, and here we are.

Lexical scoping turned up a little while after macros won the fight. Lexically scoped fexpr with first class environments are the right thing. Simpler and more capable than macros. First class environments being another thing sacrificed on the alter of performance decades ago.

Shutt noticed this and wrote about it at length. It's slightly subtle that a non-hygienic macro is a subset of fexpr. Force inline it at the caller, refuse to run various calls (e.g. pass it to functions), wrap the return value in an eval in the caller environment. A hygienic macro has to do reflective symbol renaming stuff which is also expressible as a fexpr by implementing the symbol renaming rules of scheme, which thus far I don't have the patience for.

Qualified as minor, in that the wrong thing we have is still very useful.

Disaster in the sense that we could have fexpr if history had happened in a slightly different sequence.

Opportunity in that lisp can be better. First class environments and first class macros can be done. The performance constraints of the past have been removed by hardware progress and to a lesser extent by progress in compiler design.
To my understanding, the main difficulties are:

1. The investment needed for a real "free" Wi-Fi chip is much higher than most people's (FPGA, DIY, enthusiast and garage guys) imagination. I won't go through all the complications (not only design, but also tool chain, cell libs, etc.) here. Just one hint: think how many thousands pages are there in the Wi-Fi standard pdf, and how many test cases/vectors would be extracted from that before the actual tape out.

2. The chip business is purely the game of volume – if we want to not just burn money, but actually make it successful from the business point of view. We discussed with some businessman, investors and big companies in the chip/Wi-Fi industry regarding the "free" Wi-Fi chip business opportunities and failed to convince any of them. In other words, so far, no serious man actually believes that the "free" Wi-Fi chip could be financially successful.

(Keep in mind the game of volume). A key question to you: Will you buy a Wi-Fi dongle (with free Wi-Fi chip) with higher price and lower performance/functionalities (This is the result of low investment and low volume compared to those big players: Qualcomm, Broadcom, Mediatek, Realtek, etc.)? Even if you say you will, could you estimate how many people are there like you in this world? For chip: NO volume == NO business.

This is Xianju who created the opensource Wi-Fi chip project openwifi: https://github.com/open-sdr

It is still in FPGA status, not a real chip yet. We have been working on this for 7 years (starting from the time project setup internally).
It's probably a pretty favorable comparison anyway. Asphalt is almost 100% recyclable. The demolition often just involves a single bobcat and a dump truck that hauls it to the recycling plant. A commonly used number is 10kg/tree/year for the first 20 years of a tree's growth so a plot with 25 trees would remove ~250kg/year. A gallon of gas releases about 10kg of CO2, so in that 20 year period, the little plot would capture about 5,000kg of CO2 or ~500 gallons equivalent.
So they track this down to some guy in Russia. Then what? Tracking down these types of criminals is probably the least effective things law enforcement could be doing because it's quite time-consuming and a lot of the time it gives you no concrete result.
Ya, usually paired with significant political capital as well. Ranchers in the west make up a mess of state legislatures, are strong conservation advocates (although in an indirect/slightly selfish way), and so on. If I had the money to plan for and survive the land-value tax issue, I'd probably buy a mess of land and hand it back over to an operator.
I almost bought a tesla until I read the github site on how to inspect your tesla before accepting it (I live close to the factory). Because I don't want to spend 2 hours inspecting my car for basic fit and finish and other problems, I found out instead that Toyota makes a RAV4 plug-in hybrid and I bought that- they were nearly unobtanium but with some effort I found one for a not-unreasonable price.

I don't drive much and when I do drive, I typically stay within the hybrid's battery limits and recharge right after. I refill with gas about every 3 months. It's a rock-solid toyota that I expect to drive for another 5-10 years and then resell.

I can see folks with all-electric struggling with long drives- one guy found that nearly all the rechargers in tahoe ski resort parking lots were broken or in continuous use. The plug-in hybrid seems to be perfect for my use case.

For me it’s movies. But the fact that Netflix and Amazon haven’t updated their Quest apps in years — nor has Meta bothered building its own movie streaming solution (e.g. making the Quest Browser compatible with streaming services) leads me to think that the active user base might be slim.

A decade ago I worked on the first version of the (current generation of the) main touch screen in John Deere equipment. I haven't watched the full video, but you can see it in some of the clips. Neat to think that some code I wrote a decade ago is likely still running on these things.
Nice. Here are two passages that remind me of "history repeats itself".

> Looking back it seems such a simple idea to replace the hierarchical structures used to build databases with tables of rows and columns

> First of all, XML structures are fundamentally hierarchic; thus, all of the intrinsic difficulties with hierarchies that we experienced all those years ago-with IBM’s IMS product in particular-are rearing their ugly head again.

What I mean: the relational model has replaced existing hierarchical models. Isn't that proof by practice that the underlying mathematical model (set theory, predicate logic) is extraordinarily well suited to cover data structuring and information modeling in computer science. And, yes, hierarchies are also first-class citizens in relational models and can scale beautiful.

Even the developments, yes, "hypes" of recent years and decades such as NoSQL or knowledge graphs and graph databases have not fundamentally shaken this, but we are increasingly seeing a return to the proven relational model. Hence "history repeating".
> Animals are hard work and I don't understand why any small time farmer still does it.

I guess it depends on the animal, and how many. I work sometimes on a hobby farm with around 30 pineywoods cattle and they're almost maintenance free. The hay is more work than those cattle and basically all we do for that is drive tractors around for a few days, a few times a year.
You don't need to homestead. There is relatively inexpensive housing in many areas and even some entertainment and dining options. Heck, I'm within range of going into Boston for an evening/night and I'm pretty sure where I live is much cheaper than in the city or immediately outside. (And when I moved here, there wasn't even much tech in the city proper.)

- [Benevolence to fellow competitors] Did they not want to takeover the existing market of virtualized VR desktops?
That investment was done to a degree that upkeep is to expensive nowadays.
I don't think there's a good one-size-fits-all rule. A 3 bedroom unit could be 3 couples living together and splitting the rent, or it could be 1 family, or it could just be 1 person who wants an office and a gym. The rule should probably be "1 space for car owned", like when you go to buy a car, you have to prove that you have a place to park it.

> having more places to walk, bike, and explore that aren’t just cookie-cutter boilerplate-esque suburbs and freeways would be really nice.

We're at a critical juncture here in the Twin Cities. The state DOT needs to re-build the interstate that cuts right through the entire metro area (I-94) for the first time since it was first built 50 years ago. There is a serious proposal to remove the interstate entirely and replace it with a street. This would be amazing, the area around I-94 is, as you'd expect, quite unpleasant to be in. It's noisy, dirty, and dangerous. The interstate is infamous for being one of those roads that was planned to run through and destroy working class and Black neighborhoods in the 50s and 60s[1], and removing it would go some way to regaining what had been room for people to live. I think it's a bit of a longshot, but dang, I would love to see the cities recover that space for the people who actually live here, not just those who are driving through it. It's a once-in-a-lifetime opportunity and I'm really hoping we don't blow it by just rebuilding the stupid thing.

Major European cities with no such minimum parking requirements do fine. They have public transport and bike infrastructure, so many people in dense urban areas don't need cars.

Anecdotally this seems to be true, if only because companies that aren't actively doing layoffs are at least restricting hiring.

Unemployment can be low statistically, but for those 10s of thousands who find themselves unemployed it seems like a rough job market.
That is what I do. But we'll lose the office or downsize if enough people commit to hybrid or WFH, and I'd probably have look for another job with a firm that has committed to RTO.

I'm hoping these things self-select to a happy equilibrium. I'll fill in the folks that left due to RTO, and they can fill in for my company that has a hard time finding talent in a 2nd or 3rd tier city?
Picolisp is excellent.
I feel like this is a gut-level response based on history with the iPad, but doesn't translate to the Vision Pro.

I think it's meant to be used with a Mac for most productivity use cases. That's how I intend to use mine: VSCode, terminals, compiling all happening on my nearby laptop with the Vision Pro as "just" a 4K monitor, and then extra apps like Slack, Zoom, Safari, Mail, music, etc, floating around as native visionOS windows.

In addition, it can be used as an iPad-like media consumption device, e.g., on an airplane, but I see that as an additional (and for me only supplementary) use case.

>and increased risk of identity fraud that we endure.

The problem is even worse than that. The whole framing of the issue of identity theft as a thing that happens to a person rather than a bank is problematic. That the bank issued credit in my name to someone other than me really should be entirely their problem, not one that probably messes up my life for years.

The FT pushing the natalist agenda again. Obviously that suits most business circles.

However, while Korea's birth rate is perhaps too low, indeed, we should aim at, and embrace, population decrease. That really is the best way to ensure both quality of life and environmental sustainability.

It may also be worth noting that a population of 24 million in 2100 would still be higher than it was in 1953. Perhaps in 1000 years historians will study the population blip that occurred in the 20th-21st century...

There's a bunch of VR games/apps that are notable for fitness. Beat Saber is the most well known one that's explicitly a game, Supernatural is maybe the most famous one that's framed as more of a fitness app/service.

But other notable ones include Synth Riders, FitXR, OhShape, Pistol Whip, Thrill of the Fight, and (maybe) Gorilla Tag. And this list is far from exhaustive.

VR is pretty good for fitness just because it can make exercising more interesting, comparable to sports without the need to coordinate with other people (and it's easy to do inside your house, if you have at least a 2m x 2m open space). Major downsides would be having that space available and sweat inside the headset.
Indeed. The biggest hospital where I live (Trondheim, Norway) is still running at reduced capacity and over budget a year after moving to an Epic derivative. Doctors and nurses are burning out, many talking about moving elsewhere. Being recently retired, I am concerned that this may not be a safe place to grow old, if the hospital (by all accounts an excellent one) is dragged down by this horror of a system.
The thing I don't get about spacial computing is: why?

I feel like being able to see everything open at once would be incredibly distracting. I like how I can swipe between app screens on my desktop so that I'm only focusing on one app at a time.

Of course I imagine there are some applications where it's useful, but to me it just feels like the Apple Vision Pro is just a very large screen and they haven't quite figured out what to do with it.

The tolt gait is shared by a couple other breeds and is identical in beat to the rack gait of the American Saddlebred horse, but differs in appearance.

There are six gait categories. Walk, trot, amble, canter, gallop, and pace. The tolt is a form of amble and the flying pace is a pace.

Many breeds of cart horse have a pace gait, the Icelandic is unique in having a pace gait that you can ride, most/all others have too much side to side motion to ride.

Horses from non "gaited" (having more than the four primary gaits) breeds can be taught other gaits, notably the Morgan is very good at picking up a pace.

> If someone is clearly informed and they still don't care, that's totally fine.

Let's be honest here, how many people are "clearly informed?" That's fuzzy definition. I'll give a personal example here[0]. Certainly the implications here are operating through fairly abstract and indirect mechanisms (it's even called "metadata") and most people are not trained to operate within these types of frameworks.

FWIW, no one seems happy with the situation but feel that they have no choice in the matter. It's said that you can choose not to use said service, but often the implication of that means no phone, no internet, no computer (at least non-linux), no bank, etc. There may be a literal choice available, but not a reasonable choice. I think we need to have a clear distinction between these two, because the literal choice is often used to justify something that would have major impacts. I think it is difficult to argue that one could create a reasonable and relatively average modern life with no access to phone, internet, or computer. It also then clearly becomes "well I'm forced to share with x people, so I guess I'll share with y" and often x is "the government" (even if it isn't).

[0] I've on several occasions had conversations with my family where they've been convinced that their phone is listening to every conversation they have (this dates back to 2010 btw but continues today) because they were served ads for something they were talking to about with a friend, in person. They are convinced that is the only way that such an inference could be made rather than through knowledge that the friend made the purchase (recently), that the companies know these two people are standing right next to one another for an extended period of time, and have a decent knowledge of their interests to infer that this product would be likely discussed by these two people. Ironically the recording is more complex, but it appears simpler. Sure, setting is different in 2023+ but we know the compute costs to process every conversation and energy requirements to be always recording and that this would kill phones of the 2010's.

Did you consult with any Iwi about this?
You say that and the first thing I'm thinking is, surely revolvers must be safe to use without these adapters then? They eject gas around the cylinder and are cycled mechanically.

And yet, the Alec Baldwin fiasco:

> Dave Halls, assistant director on the movie, told investigators he failed to inspect every round in every chamber of every gun on set. In his affidavit, Souza said the gun went off during rehearsal of a scene in which Baldwin, seated on a church pew, pulls his firearm from its holster and aims directly “towards the camera lens.”

> According to the Los Angeles Times, half a dozen union camera-crew workers had walked off set in protest of working conditions just hours before Hutchins was shot. There had been three misfires of the prop gun before the one that killed Hutchins. “There were no safety meetings,” an unnamed crew member said. “There was no assurance that it wouldn’t happen again. All they wanted to do was rush, rush, rush.” The Times reported that someone texted the production manager, “We’ve now had three accidental discharges. This is super unsafe.”

> But a huge cache of documents the bureau released after the report suggest Gutierrez-Reed may have known live rounds had been detected on set ahead of the fatal shooting. In published text messages, Rust’s prop master tells Gutierrez-Reed she found “bad ones” in the box of ammunition. “Hannah advised she thought it meant possibly one or two rounds from the box, but Sarah told her it was more than half of the box,” the summary reportedly read.

Lesson learned: if you want to engineer an on-set firearm accident, use faulty revolvers, heavily contaminate the supply of blanks with live ammunition, and make sure everyone is rushing through everything at all times so crew is conditioned to ignore warning signs and nobody knows who to blame when tragedy occurs.

Well played, Alec. Next time just do Springtime for Hitler.
