"transition" is signal changing, from high to low or from low to high.

As described in the page, there are multiple signals changing when operating floppy ("track 0", "write gate", "data", etc..). Of them the fastest one is "data", so that's what I am going to focus on.

The 2nd page of writeup [0] says:

A short transition (S) will nominally have 2us between bits, and represents 0b10
A medium transition (M) will nominally have 3us between bits, and represents 0b100
A long transition (L) will nominally have 4us between bits, and represents 0b1000

So we are looking at 3, 4 or 5 microseconds between bits. To get this in CPU cycles, you multiply this by clock frequency - google can help you with units, searching for "2 microseconds * 600 megahertz" [1] shows the answer, 1200, right away. I've rounded this down to 1000, as there are two transitions per pulse and it is all very approximate anyway.

And then you use your embedded knowledge to assign meaning to the number: the CPU is ARM, so 1 instruction/cycle is a good approximation (it could be more due to dual-issue or less due to jumps). So you have like 1000 instructions. Each function call in language like C or C++ might be a 5-20 instructions overhead, and you probably want to read that pin at least 10 times to detect both transitions. The tightest loop is also going to be a dozen instructions or less (read gpio, mask, compare, maybe jump out, increase, compare timeout, loop)

So.. you can do it in C/C++ easily if your main loop involves no function calls (and you have no interrupts). If you use functions to read, your timing is going to be tight and those functions are better be super-optimized, you will be asking your compiler for a lot. Higher level languages like lua/micropython are out of the question (at least for that loop). And as I learned from reading this, rust is also out of the question, although I wonder if there are some unsafe primitives which do not do any checking.

(and yes, there are transistors changing in the background all the time throughout the process, but I really don't care much about them, they are on too low of the abstraction level)

It’s called a recall because that’s the name of the legal mechanism used by the NHTSA to make sure a manufacturer tracks all of their vehicles’ remediation. If this bothers you, contact your congressional representatives asking them to force it to use a more marketing-friendly name.
Very debatable, if both are done right.
> To the contrary, the lineage that underpins modern computing traces directly back to Apollo and the work that supported the program.

No, that was mostly the USAF, not NASA. At one point, the USAF was the largest buyer of transistors. There were transistorized computers as early as 1953.
The USAF had a transistorized computer in a plane by 1955. DEC was founded in 1957. The Minuteman missile (1962) had a digital computer onboard.

And no, NASA did not develop Velcro, Teflon, or Tang, either.
Agreed and I want to highlight this comment. Skip everything else and go straight to the Lorraine Motel / National Civil Rights Museum. It's basically the opposite of a waste of time. For those that don't know this is where MLK was murdered and is now a museum / memorial.
Does that makes bureaucracies weirdly whacky-resiliant in exchange for more bullshit and red tape on the edges?

I'm genuinely asking, your comment triggered the thought.
This will not help. Humans are fundamentally incapable of babysitting repeptitive boring tasks that require interaction only in failure cases. Expecting humans to do so is expecting superhuman capabilities and no amount of threatening the drivers with legal consequencces will change the outcome. All you'll achieve is punishing the poor sobs that trusted teslas marketing stunt.
If you want this to change, make Tesla liable and they'll quickly fix this, one way or another.
A regulator-forced over-the-air update is still a safety recall.

The important part is "they were required to change something", not where the maintenance physically occurs.
Just hope they aren't using Xerox to digitize those documents. That glyph substitution bug from a few years ago made quite a few would be digital archivists rather unhappy.
That would require a complete revamp of US law and culture. As it is now, you are not a criminal if you stop paying attention and run someone over. Your actions have to rise to a much higher level of wanton criminality before you are ever at risk of a criminal charge. People kill people on sidewalks, in cross-walks, in their living-rooms (!!!) and face nothing more than a $1000 fine for failure to yield.

This kind of change isn't impossible. Drunk driving was once in this same category -- I.e. considered an unfortunate accident rather than a crime. Then Mothers Against Drunk Driving (MADD) ran a 30 year campaign to change the law, change enforcement, change prosecution, and finally (partially) the culture.

But I guarantee the NHTSA has neither the mandate nor the capacity to lead that change.
> A lot of the debate is very sincerely ...

I suspect a lot of the debate is very insincerely arguing that.
ROFL.

I'm better at simulating NPC behaviour than I thought.
You guys are trying to discredit the statistics here, but anyone in the Bay Area knows this is true. I wish there were stats on “near accidents” because Tesla drivers would be leading that too.
How many homeless people do you interact with daily? Because I'm forced to interact with many of them on a daily basis to simply go about my life in the Bay Area. And almost all of them, with very very few exceptions are both mentally ill and drug addicts. I used to think like you, but being forced to deal with them in real life on a daily basis has a way of killing preconceived convenient notions.

Polar opposite of what I want to be.
It's crazy to me that we use the word "recall" to mean "mandatory software update". I have no problem with NHTSA (or whatever) requiring car companies to do updates for faulty software, but the word "recall" is completely inappropriate for this process. A recall should mean that I have to drive it to the dealership to fix/replace some defective hardware component. If I don't even know it happens because the car downloaded a software update overnight, it's not a fucking recall.
The fact is that there are different sorts of people. Some people know what it's like to do deep, sometimes difficult, independent work on their own. These people have all been ICs in some field. There are also people who have been ICs who have never known such a feeling. And then there are people who have only ever been managers, who also have never known such a feeling.

According to the article:

"Those who got the stipend were less likely to be unsheltered after six months and able to meet more of their basic needs than a control group that got no money, and half as likely as the control group to have an episode of being unsheltered."

Thats what my chess teacher used to put me in their local chess club tournaments, in order to get a FIDE Elo, i would have need to go (on that time 1995~1999) to official tournaments and that was expensive for a rural area...

M not saying m on the level of masters but definitely not a newbie... either way i don't need proof just go to chesscom, open a new free account and start grinding... you are gonna see fast the pattern on how the platform gets you engaged but you need to look careful, it entices you with free wins before going hard on you, having three to five games a day was the eureka moment to get good ratings... either go slow or pay premium to get an edge on the game and preferred match making.

I haven’t used JavaFx so I can’t answer that part of your question but XAML has been cross platform with Xamarin on macOS and Android and now everywhere with MAUI. I also mentioned Uno which lets you develop for web/electron with XAML.

Language wise, it has been largely C# or other .NET like VB.NET, F#, or managed C++ though I think Noesis lets you use it from C++ and other languages directly.

C# itself is completely uncoupled from Windows ever since .NET Core and now with later .NET versions like .NET 8 all Windows-specific bits have been torn out altogether. Microsoft probably uses C# on Linux more than they do on Windows these days.
The special-casing of Blocks irks me, including the fact that you can only have 1 of them in a single method call. I understand the justification, but it’s syntactically inconsistent and doesn’t sit right with me.

I really like the way Swift introduced closures as regular parameters, but lets you have the Ruby-like “trailing closure syntax” for the last one in the list. It’s very best-of-both worldsy: if you need just one closure, it can be trailing, and if you need multiple, they can both look the same.

I'm not sure about the history of these words, but astronomy also uses the noun form: "occultation" [1], for which there's not an obvious equivalent for "occlude."

> Did occult mean what it does now when they started?

A word can have more than one meaning. The first definition on merriam-webster.com covers the definition used in astronomy:

occult (v.): to shut off from view or exposure: cover, eclipse [2]

The adjective form might be a source of derivation for the meaning you're alluding to:

occult (adj.): (1) not revealed: secret; (2) not easily apprehended or understood: abstruse, mysterious; (3) hidden from view: concealed [2]

And finally, the paranormal meaning that people are more familiar with today:

occult (n): matters regarded as involving the action or influence of supernatural or supernormal powers or some secret knowledge of them -> used with the [2]

Again, I don't know the history of these words. If I had to hazard a guess, I'd bet that the noun form, "the occult", is derived from the adjective form since "the occult" refers to supernatural phenomena, which is naturally hidden from view, concealed, not revealed, secret, not easily apprehended or understood, etc (because it's not real).

Edit: Another guess. If you think about the history of astronomy, it was originally intertwined with religion and astrology. Perhaps these words date back to a time when "the occult" and astronomy weren't entirely separate. Anyways, I agree. Language is strange.

> But you literally cannot possibly test that assertion for all x.

Hence why he states it is formal verification for the "unwashed masses". The "washed" will use a language with a type system that is advanced enough to express a formal proof, but most people can't hack it, and thus use languages with incomplete type systems and use testing to try and fill in the gaps.
Selection bias is a strong effect here.

The first rule of real-time computer graphics has essentially always been "Cheat as much as you can get away with (and usually, even if you can't)." Also, it doesn't even have to look right, it just has to look cool! =)

Weird, I do. I live within a minute's walk of three separate encampments of homeless people, most of whom seem reasonably sane when I talk to them, and if they have drug problems they certainly aren't more apparent than those of my coworkers on average
GIMP hasn't even migrated to GTK3 yet. The upcoming GIMP 3 will finally use GTK3 and is slated for release in a few months, but this is years after almost everyone else. Certainly in the case of GIMP I think "lack of resources" can be substantiated pretty easily. IIRC GIMP 3 will also get Wayland support – I'd have to check to be sure.

I'm less sure about XFCE or Enlightenment. Judging from [1] the XFCE people have been working on it since Feb 2021 (when that page was created), but real issues still remain, and I'm not surprised that "let's do a substantial rewrite of much of our codebase from something that works perfectly fine to ... something else that works perfectly fine" is not hugely top priority for a fairly small project like this. Call that "people being roadblocks" if you will, but that doesn't strike me as fair. Neither of us get to decide where these people spend their time.

If the main selling point is that it's non-rewritable, it seems like this could be accomplished with existing storage tech. For example why not have a spinning rust disk with a physical interlock switch to prevent writing? Then the disk could still be manually wiped and reused. For important textual data, burning DVDs should be totally sufficient.
WORM tech is ancient though so it's not as if it's a big advancement against ransomware IMO.
Ironically, the article leads with a parable of some dork being overly tendentious about word definitions.

Maybe you could give it another chance.
There is no analysis done to be included in the S&P500. It's 100% rules based. It's extremely unlikely that a stock like NKLA would ever qualify for the S&P500 but it was included in the Russel 2000 (also rules based), and by definition in any total stock market index fund.
When I first started learning about stock markets I got a lot of insight from one comment a friend (who had gone into finance) made to me: the stock market is not a vending machine.

There is no set price to buy shares. If you just want to buy 100 shares at the current ask, it'll probably go through (but even that is no guarantee), but the next 100 shares might well not be available at that price anymore.
> I think these usb-c pd (and other) issues were corrected in the oled switches and the docks that come with them but the fixes might not have been total.

I have the OLED model, and the accompanying dock refuses every single non-Nintendo charger I've tried. It literally tells me so on the screen.

> My theory has been that not all usb-c chargers are compatible with all voltages [...].

Correct. Both devices present eachother with a list of supported modes, and negotiate the optimal one. If you try a fancy charger/powerbank with a screen, it will even present per-port current/voltage stats. Fun to observe the changing power draw on different devices.

Also if you plug another device to the same charger, it will trigger a re-negotiation, possibly end up in a different mode. LTT had a whole video on modding ancient consoles to use USB-PD, and the possible resulting issues.

Ask HN: What companies offer maternity/paternity leave immediately?
I have observed that most companies don't offer their leave benefits until you have a year of service at the company. Also, companies don't really advertise the specifics of their policies publicly.

What are some companies that offer leave before you hit that year tenure for both maternity and paternity?

I don't think I ever got a stable disk above 1.6MB. Which was just enough for a few things but generally not worth it.

The motors in the disk drives could be controlled directly, and you could pack the tracks tighter by stepping the motor just a little bit less than you were supposed to. And in theory if you did it right, other disk drives could read it.

'In theory' is carrying a lot there. I tended to find 1.5something to 1.6something worked and anything higher rarely ever did.
I'd add that our current workflow is to complete our webapp designs using code components and deploy via Vercel as a prototype. Later we aim to publish production directly from Plasmic. These little steps are addressing cultural issues mostly, a the idea of a design team publishing the FE touching a lot of cultural issues and fears like reporting lines, processes, job loss - change is scary.
The fact that you call all homeless people "mentally ill drug addicts" is very telling. Do some basic research. I hope you find some empathy in your heart.
The problem with CISSP and similar is that the US government wants certifications, the 'software industry' is totally disinterested in such a thing, so the 'certification professionals' have moved in and set up shop. It's hardly the same level as a Professional Engineer or similar accreditation that is required before you're allowed to sign off on 'real engineering' projects.
Whats the difference between this and Builder.io? both no/low code apps with a CMS as its base. Drag and drop for UI, auto-code generation and plug into back end of choice.
I think there are trade-offs. Small local media is vitally important, but the problem implicit there is that biasing towards small, local media also means diverting funding to small teams that may or may not be high quality. For every Indiegraf, Tyee, or even small town papers like the Flin Flon Reminder, there is a Rebel Media that is just a microcosm of everything wrong with the media.

We wanted to support tight integration with people's existing codebase, so that it is easy to use your React components directly in Plasmic, or to read data from your React contexts provided from outside of Plasmic, or to have your code components communicate with each other via React contexts when they're used within Plasmic, etc. There's power in being in "one React tree" with your existing app.

I imagine it's possible to achieve this with other frameworks too, though the integrations would be deep and bespoke for each framework. We've just decided to focus on React first.
