It would've been cray-cray to boot them from a single board with extra flash via SWD. Does anyone know how fast the RP2040 SWD clock can be driven on a Pico soldered to a central board? How many DMA channels and PIO state machines would be required to build an even faster remote memory access interface? Can a central 9th RP2040 serve as fast RDMA router for 8 other Pico boards? So many unanswered questions ;-).

One way the RP2040 really punches above his price class is internal bandwidth. It has four AHB-Lite bus masters (two M0+ cores with one read-write port, and the DMA engine with a read and a write port) connected a full crossbar switch. There are six SRAM banks of which the four largest are commonly used word interleaved, but can if you want full control over memory timing and bandwidth you can use the uninterleaved alias instead. Most chips priced around a RP2040 (and the SPI flash to go with it) have only a single small SRAM bank. I've found the DMA engine surprisingly pleasant to work with (easy to understand, no fixed request routing to fight, but still very flexible which can save a lot of interrupts). Whoever designed the combination of the PIO channel I/O coprocessors and this DMA engine had a clever tinkers mind. I have to stop myself from wasting time looking for ways to save CPU cycles with trickery that only makes the code hardware to maintain.
I believe that current car racing trends will paint a picture of the future of automobiles.

The hybrid area is among us, and the technology used is so well thought out and advanced.

Hybrid as in “go incredibly fast”, and not “save gas” like as with a Prius.

Currently in F1 and the new prototype classes, they are using electrification in conjunction with the internal combustion engine to create more instantly available horsepower.

They are using twin turbo 6 cylinder engines, and anything that has large rotational mass has been electrified with motors. The turbos, crankshaft, and camshafts all have hybrid electric assist motors built into them to combat inertia. They then have incredibly engineered heat recovery systems built into the brakes and turbos. They collect the heat and convert it into electric to recharge the battery. Additionally, when the electric assist motors aren’t providing power to their components, their function is reversed and they become generators that also feed to the battery.

I don’t believe the streets have ever really even seen electric assist turbos and crankshafts lol. Ford only recently realized that you could make more fuel efficient and reliable power with less displacement using forced induction.
I think the article incorrectly summarizes the judge's order. The order makes clear that it was a lawyer telling the plaintiff that the _US state_ barred the action.

I don't want an independent userspace implementation, I want the verifier the kernel uses. I'm was looking into this and I'm not sure why it can't be pulled out. I guess depending on what you're plugging the eBPF into the environment (functions, etc) may be tightly coupled to the kernel, but surely the loop analysis and stuff could?

It basically forces you to program on a live system. No CI, no static analysis, no editor help, etc.

These are just packaging issues, typically (but not only) on Linux. Dedicated developers know what to do to avoid all of that.

As for the style - again, depending on developer choices, they can actually be the most consistent with the platform they run on. Unfortunately that was a selling point for the original QtWidgets more than QML - QML does things "the web way" and just doesn't give a crap about desktop styles.

Things like "lack of padding" sound funny to me, because on that side Qt is definitely superior to the overpadded monstrosities of GTK or web-like frameworks, who waste screen real estate for fun. Qt simply uses desktop conventions, which are "just right" in QtWidgets with minimal attention to layouts.

Now you're just being silly. Everyone does it - Apple with NS etc.
Good. It’s unethical to profit off of helping other people cheat.
> I found a tourist planning site that said the average tourist in SF spends $32/day on meals

That can’t be right. A burrito or sandwich costs $18-$20 after tax, health mandate etc, and that’s at a walk up and buy kind of place.

If you get fries with that, it’s another $6-$8.

A sit down meal? Probably 50% more. I don’t see how $32 is a reasonable estimate.

I’d guess closer to $50

> Because it's evil Russia attacked poor innocent Ukraine in 2014

The poor innocent Ukrainian government did pass a bill to prohibit official use of minority languages on the eastern part of the country (dominated by Russian-speaking population) on a Sunday morning of February 23, 2014. It happened a day after their president had to flee the country. It was clearly a period of political crisis and no one was supposed to work and enact any legislation on that weekend day in the first place. No one was supposed to pass a bill of that significance without extended debates and a referendum specifically. But the coup leaders decided to move forward with it nonetheless. Russian troops legally stationed in Crimea took over the peninsula 4 days after that punitive act of the Ukraine government against its own russian-speaking population of the eastern part of the country. The reinforcement from Russia were only sent 6 days after the event, as the Kiyv regime decided to escalate.
Both Seattle and Portland are basically homeless junkie camps.

I lived in Seattle for 12 years and left in 2010. I went back a few years later to visit and it looked like the homeless population had doubled in the time since. It's honestly gross how bad it is. The city has so many problems and no idea whatsoever how to solve them.
Kenyans are super cheap. With an average yearly income of roughly $2500 USD, that’s not even more than a single paycheck for a typical software developer.

IMO, it doesn’t make sense to purchase expensive licensing to use GPT, when you could easily hire a living, breathing Kenyan to actually write stuff for you.

With a bit of training, Kenyans can become well suited for general purpose organic workloads and open ended tasks requiring high degree of intelligence and subjective analytical skills. Horizontal scaling is relatively straightforward and Kenyans will cooperate with each other with very little configuration required. Kenyans also do not require nearly as much prompting as GPT due to their innate intuitive abilities and superior comprehension skills. They possess great capacity for novel creative thought without extra input stimulus.

The typical downsides of organic computation pipelines still exist: Unlike an AI, Kenyans can suffer from burnout or have inconsistent performance metrics, they are also much slower to produce outputs. There is a high degree of variability between Kenyans due to poor quality control, nonetheless it is easy to replace a Kenyan with a new one.

Consider Kenyans.
Ah yes, but the war Russia (as Russia, and not the USSR) lost was fought on Russian soil.
Correct. But for all practical purposes they were lisp machines, you turned them on and got a lisp prompt, not a basic prompt which was the more common language to boot into back then.

Wikipedia says the Cray-1 was capable of 160 MFLOPS.

As a rule of thumb, modern scalar pipelines can sustain one ALU op per cycle, and you see nearly all Linux-capable CPUs quoted in GHz. So we should expect gigaflops, minimum. And indeed [1] suggests that the Pi 4 is capable of 13.5GFLOP, so about 84 Cray 1's. (The further speedups come from the fact that ARM also has NEON vector instructions, and from multiple cores.)

The Pi Pico, on the other hand, does not have a floating point unit. So it emulates it in software (soft float). The C SDK docs [2] suggest 13.8kHz (!) operation for single-precision add. I'll be generous and suggest that the 2x cores could double this performance. So then, it'd achieve 0.0086% of the Cray-1's performance. Oof.

If you're willing to do integer arithmetic, things look much better for the Pico, of course - it runs at 125MHz and the above scalar rule of thumb applies.

Because BMI doesn't distinguish between Arnold Schwarzenegger and The Whale. If you're overweight for your height, even if it's solid muscle, it's all the same to BMI.

Different body fat percentages for men and women is likely how they already do it.
It's a necessary idea. The pool of people willing to join and fit enough to get through boot camp has shrunk enough that the military has been missing their recruiting goals.
I wish they would copy-paste Blender's UI, shortcuts, and some of the logic. Things like edit mode in Blender versus node edit in Inkscape, so I don't accidentally click on another path. There are several operations that don't have hotkeys, like layer/path visibility... They've sorta moved in the UI direction with modifiers in the dev build.

As it's currently tooled it can't be set up to align with Blender, really at all, which is really annoying. The box zoom for example frequently trips me up, but that's inconveniently my muscle-memory for panning.
Incidentally, having listened to a few clips of the language, it sounds like it has a slight Arabic tinge in some words. And otherwise reminds me of Russian, and sometimes Hangul.

You can argue that about anything.

Economies are too complex to judge any one person’s choice of how they participate in them. If starting a business (or being a journalist or writing a novel) was a better idea, perhaps some of those Kenyans would have done that. But writing college essay brings (brought?) new money into Kenya that can be reinvested in new businesses, journalists, and novels. In the absence of non-corrupt foreign investment in Kenya I think this could be a big booster for their productive economy.

Or maybe not. But who are we to judge?

BMI among fit individuals and athletes, is a terrible indicator of overall health. There's no distinction between a 250lb 6' man whose weight is predominately muscle vs a 250lb 6' man whose weight is predominately fat.

Having a high BMI and a low body fat percentage means that you are likely composed of a lot of muscle weight. I would think that this would correlate highly with physical strength, which I would also think is something we would want for our fighting forces.
Testing a 96-Core Ampere Altra Developer Platform
I found it interesting that they talk about body fat % when that’s notoriously difficult to measure. AFAIK only an MRI is accurate.

Then trying to Google what the actual test is, there’s a lot of advice about how to manipulate water weight to cut enough to pass. So this change is probably way better for those borderline people who were doing unsustainable stuff to pass.
Isn’t there already some sort of path to citizenship via military service? I suppose that you’d probably have to at least be a resident though.
You're being downvoted, but you're not wrong. I was in Portland for a week each in 2017 and 2018. Sure there were a lot of homeless on the streets, marijuana smoke was in the air, but the downtown area was still very nice.

I went back in March 2022 and it was completely different.

I hadn't seen shit on the sidewalk my first two trips -- it was on every other block this time.

Dozens of stores still boarded up, most of which I imagine had closed during the 2020 protests. Graffiti everywhere.

I won't be making a trip back.
Either way, a smart move by REI.
BMI doesn't distinguish between weight by fat or weight by muscle mass. Someone with a lot of muscles and not a lot of fat can still have a high BMI
It’s more or less the same thing because if your fuel price doubles you’re going to scrap that car and buy an electric.

Nobody is forcing you to do so, it just doesn’t make much sense to keep driving that ICE. When everybody is making that decision parts and maintenance will be more expensive and harder to come by too - accelerating the transition.
I imagine that some roles that used to depend on height and weight requirements are shifting due to remote piloting.

The article has this interesting note:

>Whatever their body composition when they join, new airmen will be subjected to the same annual fitness tests and standards as everyone else.

Which I guess means the Air Force thinks they can get folks who would otherwise not qualify into shape.

If you've ever done woodworking, you'd appreciate the imperial system, especially when working with kerf size and whatnot. The imperial system was literally made for that kind of application. Rather, not made, but it emerged.

The imperial system emerged piecemeal as a series of domain-specific measurements, where each unit conveyed deeper meaning beyond rote volume, distance, etc. For example, an acre means much more than 43,560 feet squared. It means "roughly the amount of land that a pair of oxen can plow in a day". A nice domain-specific measurement that communicates something useful to the experts of that domain, in this case, plowmen, farmers, and lords of the manor.

With inches, an inch is about the length of your thumb. Imagine doing woodworking and measuring in thumbs - it's right there in front of you, easy to conceptualize and work with, an intuitive "bite-size" unit of measurement. Fractional centimeters aren't as intuitive to work with and conceptualize. 6+3/4 inches is a lot more workable than 17.14cm.

> you are building home equity.

The interest portion is the price you pay to be able to purchase that equity. Compare how much does get thrown away, and the value of that tiny slice of equity relative to other investments. Maybe Big city real estate is really that good (it seems better to me than anywhere else).

Furthermore a 30 year mortgage in the Bay Area locks you into a high earning life style These are somewhat stressful jobs with market ups and downs. It almost becomes impossible to pursue an alternative, like a career change.

What about selling and moving out? You can, but if you're forced to that situation is also where you incur the most real estate risk (high transaction costs, forced to sell underwater, etc).

The recruiting goals are inflated due to low retention, retention is low due to low morale but also because of high employment rates. When it's easy to get a civilian gig less people stay in, especially among technical rates/MOS's.

Hub and spoke is primarily used to fill large planes. If you have 10-20 passenger electric planes you'd land at some random county airport, eat a hamburger or a taco while the plane recharges, then get back on the same plane and finish the trip. So you'd have a layover like hub and spoke but all the concerns about missing connections go away.
Whatever prompt the Kenyans in this scenario are receiving can just be entered directly into ChatGPT
In a retirement home $50 a month is a bargain to be able to walk through and relive all of your life.

It will be an MMO fine-tuned on your cloud data such as videos and photos. Surviving family members across the country and co-prescense with you to relive that Grand Canyon rafting trip.

The edges will contain infinite generated content that rhymes with your lived experience.
One of my main use of AI right now is using it to answer legacy questions. Searching for old AngularJS (not Angular) question online is painful, yet ChatGPT is able to come up with explanations, code snippets and even outright provide code based on prompts.
It’s funny to see how defensive people are about their body fat %/bmi etc. It is objectively bad for you beyond a certain point and if that “personally offends” you it is more of a you problem than a problem with the person pointing it out.

Data integrity is maintained through FK, unique indexes, proper modeling, etc.

Also, an RMDBS is hard to scale horizontally, so the more CPU tasks you put on it, the sooner you will hit a bottleneck that is not easy to get out of. A application layer, if designed properly can scale a lot more.

>The app will be gone long before the data.

When this ever happens, it happens rarely, and the situation is the data enters a read-only state in my experience and happens during sunsetting. Most of the time, if a new system is required, a migration occurs to a new schema that the new app supports.

I do not find that BMI would be a good indicator, since (based on my own experience), people in the military are pretty muscular.

How viable is your business idea? (interactive calculator)
Jason Cohen (founder of WP Engine, among others) recently wrote a super interesting blog post "Excuse me, is there a problem" [1].

In his post, he explains why even identifying an actual problem and solving that problem isn't usually enough to create a viable business.

Further down in the post, he also comes up with a scoring system to rate business ideas (with all obvious caveats and exceptions of such a calculation).

One cool aspect of this is that you can simulate how your positioning (e.g. higher pricing, combined with narrower target audience) may change your chances of survival as a business.

Being a Google Sheets noob, I created an interactive version of the calculator and linked it above. Hope you find it interesting :)

This sorta reminds me... whenever I have a bit of free time and I'm tired of commenting on HN, I daydream about what the next generation of Atari or Commodore 8-bit machines would be like (not STs or Amigas, but something still mostly 8 bit.)

I was thinking you might get a windowing system where each window held a "Virtual 800XL" so you could run multiple apps simultaneously, and an OS that shared peripheral access to real devices. Definitely a faster SIO port. Maybe something like FujiNet to communicate between virtual XLs (and other, real XLs.) If I made such a beast today, it would definitely have a built-in SD Card reader. Maybe a built-in trac-ball and no mouse buttons since you could use the select and start buttons.
