A post about an obscure C++ feature on Hacker News? Comments are going to be a dumpster-fire as usual.

https://en.cppreference.com/w/cpp/utility/launder

"template <class T>
[[nodiscard]] constexpr T* launder (T* p) noexcept;

Provenance fence with respect to p. Returns a pointer to the same memory that p points to, but where the referent object is assumed to have a distinct lifetime and dynamic type."

It's a function for the compiler for low-level memory management and lifetime management code (i.e. code almost no C++ "end-user" writes) to turn off compile-time tracking and optimisations that might not be correct. Typically only used if you're starting the lifetime of one object over or inside another. Essentially, when you want the compiler to be dumb you launder the pointer to make the compiler intentionally forget the complex compile-time state tracking that compilers do and make the compiler pretend that pointer is actually a brand new object it knew nothing about.

Someone brought up the volatile keyword: volatile is for turning off compiler assumptions about what a value might be at run-time. For example, if you read from a regular int twice in a row with no write in between, then the compiler would likely remove the second read and reuse the first value (better code-gen) as it knows the value could not have changed. The volatile keyword is how you tell the compiler that it cannot reliably observe all changes to the variable so every read must be performed (same for writes).

launder and volatile are similar in so much that they exist to tell the compiler not to make assumptions about the values/objects, but that's about it. They are not interchangeable.

But let's all pretend this function is something everyone using C++ needs to use to farm some internet points.
But then the vendors would not be able to differentiate (ie, markup) their products.

They currently charge thousands more for adding $75 of memory.
Fascinating! Thanks for the insight. :)
For me the "transformative" aspect of personal robotics is... maintenance

Why does every store have self opening doors, but no houses do? I think it's because paying ~$500/year to get it running again when it breaks feels like a waste to almost any home owner. The same with other random innovations, like a car stacker to push your car into the garage roof when not in use so you can use the garage (the hydraulics would break), fans and pumps to move heat in or out of the house or water around the garden, they're a pain because they break, it's only worth it if you're running a commercial operation.

So homes end up with the absolute minimum number of things that could break. Calling out trades for the few things people must have requires smart people who are physically able, that have their ticket in a protected industry (in many countries). But a robot could have the same knowledge and physicality - at a fixed yearly cost.

If that were to happen, homes would transform as all sorts of things that require very occasional maintenance would start to appear. If something breaks even a very weak robot could diagnose it, find the parts online, have them delivered and probably install them.
Direct I/O from and to user space, no serialization. There are significant size and performance limits when using virtual memory to give objects a consistent address, hence why it is sometimes avoided.
I haven’t had any issues with it or needed to revert to UiKit, but I’m still fairly new to developing for the Apple ecosystem, so your mileage may vary.

For C++, you would be wrong. You can use it for variables that your code won’t change (hence const), but that can change due to outside events and hence can’t be cached in a register (hence volatile)

See https://www.embedded.com/combining-cs-volatile-and-const-key... for examples, https://en.cppreference.com/w/cpp/language/cv for a more formal description.
UL has, or had, a whole house in Fremont (maybe Milpitas) associated with their Fremont lab location for testing Wi-Fi/Bluetooth/etc interoperability in a "real-world" setting. They're not the only test lab to do something like that, either.

It would not surprise me at all if Apple had a similar facility for themselves, especially for internal demos, user testing, and sanity checks.
Yes, it does: “the purported firm needed him to ‘add a credit to our client immediately’ through a link to Tech4Gods”.
Perhaps I am being too cynical, but how do you protect this scheme against hostile actors?

Bits don't have color after all (see https://ansuz.sooke.bc.ca/entry/23 if you don't get this reference) and it would be fairly trivial to manually alter such media types to anything you want. For example if someone posts a `ai_edited(human_created(photo))` online, it would be straightforward to take the pixels of the photo and re-publish them as a "new" image with only the `human_created(photo)` tags. You could also randomly start adding `ai_edited` tags to things you want discredited, etc.

Not sure when the people you know were jumping but I've heard a few older (non-military) guys at drop zones complain about shoulder, back and hip issues from harder openings with the rigs they used in the '90s and early '00s.

Parachutes are typically sized according to weight to manage rate of descent, so the extra weight shouldn't be an issue. Given the context I wonder if the military just calibrates around faster rate of descent because it's risky to stay in the air too long.
> Office is much superior to any open source and even paid alternatives, and we must remember that most people using the software don't have a degree in CS.

Germany is investing in improving free software, see https://www.sovereigntechfund.de/. Though not sure if this is linked to that state switching.

I think LibreOffice is riddled with loads of small "paper cuts". Basically loads of small issues that make it annoying to use. I hope that they understand it shouldn't be about cost, it should be about being sovereign. So hopefully the investment (ensuring additional developers, UI/UX people, etc) increases as they use more free software,

Yes, but most people share the world view that a state lottery should not generate unsolicited lewd images of their customers.

This suggests there is a large, and perfectly reasonable demand for censored models that adhere to broadly ‘SFW’ cultural norms.

So why are people upset that commercially available models generally try to cater to that obvious need?

Depending on what your main competitor gives you is a bad pattern. If it gets adopted enough, or somewhat Google see it as a threat, conditions will change, maybe for everyone.

Think in what Reddit did when seemed that ChatGPT was trained on Reddit content, they put a price to such 3rd party requests, ended a market of good frontend alternatives for it, some tools and bots stopped working, etc.

Google could do something similar, or poison/watermark the results sent to them or even put Gemini to be creative enough with the way it send back results to make very hard to parse to send an unified answer.

It is what is available now, and it may work, but it may stop doing so because things happening outside their control.
Oh absolutely, it just has the advantage of being a well know and relatively simple machine (the vacuum), that is expected to roll across the floor, and is expected to avoid household objects instead of interacting with them.

Almost all other tasks either operate at human-hands level (significantly bigger robot) or need intimate understanding of you and your home (eg picking things up off the floor) or need a ton of dexterity (folding clothes). Or all three.
Since the labor market is competitive, they will be paid more in jobs where they are on call in the evenings, other things being equal. They can trade free evenings for higher pay.
Yeah, I mean for AM5 platform for example, it would have been awesome if some motherboards took x4 PCIe 5.0 lanes and turned them into x16 PCIe 3.0 lanes or something like that. That would benefit me way more than the current AM5 motherboards out there.

Of course, as you note, the reason we don't see this is likely because the PCIe switch chips cost more than the rest of the motherboard.

I have no doubt that more bandwidth will change how games are made, but 5v5 shooters (and pretty much all existing multiplayer styles) are here to stay for a lot longer than that, in some form or another.

Caprock Canyons Trailway in Texas [0] follows an old FW&DC (Fort Worth and Denver City Railway) track for about 64 miles across the landscape. It goes from relatively flat terrain around Estelline through some nice, scenic canyons towards South Plains, passing through the Quitaque (pronounced kit-uh-kway) area where you can find what is I think the only surviving railroad tunnel in the state. There used to be two of them but one collapsed I think in the late 1970's or early 1980's due to the steady vibrations of trains passing along the track. That's what I heard anyway. The other tunnel is still there on the new trailway and is nesting ground for a bunch of Mexican free-tail bats.

Zoom out a little since that is focused on Caprock Canyon State Park just north of the Rails-to-Trails section of trailway.

Back in the 1980's before it was abandoned by the Burlington Northern Railroad who owned it at the time, my Dad ran trains along that route bringing grain from farms at the south end all the way back to the main line at Wichita Falls where it could be routed south to Houston or Galveston for export or distribution.

It passes through some beautiful country. I have been planning to visit that park and walk that trail for a long time. Maybe this will be the year.
I remember school as a constant source of anxiety and depression. Something like Roblox where my creativity was rewarded would've been amazing for my self confidence.

I haven't actually tried playing Roblox or researching it, so I don't know about the percentages, but I'm mainly speaking about the idea of using creativity, to create fun games you enjoy creating and the end results being:

a) other people are playing what you created

b) you get paid (even if in small amounts) for what you created

Would have been amazing for my otherwise low self esteem childhood.
I suppose I'll keep holding folks hands...

So, Google's results only seem interested on showing the articles about the NTSB's ultimate findings, not the ones that were originally reported immediately after the crash. I then assumed that some of the articles I had linked in that post would probably link back to their own previous articles about it, and figured I'd just start by going through that list from the top down.

Sure enough, the second one I linked, from CBS News, linked to their older article on it, entitled, "No one was driving Tesla before fiery crash that killed 2 passengers in Texas, authorities say".

https://www.cbsnews.com/news/tesla-crash-texas-no-one-dirvin...

Edit:

>The assertion had two parts and these stories only reflect the latter.

They don't, actually. Take this line from the Ars piece (though Ars isn't the only one that says something like this - most of them do! :D), for instance:

>The possible involvement of Autopilot was suggested in the wake of initial reports that one of the two occupants—specifically the driver—was found in the back seat of the car.

If you click the Ars link, you'll notice that the phrase "initial reports" also links to their own article written immediately after the event, titled, "Cops 'almost 99.9% sure' Tesla had no one at the wheel before deadly crash".

I also am getting value from Kagi and think their AI/Summarize is really good. The search lenses are also very cool, actually its like Google was before they silently deprecated all useful operators. Honestly I hope they make it as it really is a better way to do the web.

edit: So I pay 20 bucks a month and get the "early adopter" package which is all the AI stuff in beta and its amazing. I think it completely makes Kagi much more desirable. Its a lot of money but I don't use any streaming services anymore and honestly just learn stuff and mess with LLM's to kill time when before I was watching something. I guess its not for everyone but I am surprised its not an instant buy for [more people in the industry.
I don't know, it feels like it's more driven by investors than anything. Everything is free money, there cannot be any downside type thinking. Like the Fed is going to cut rates without that also implying a slowdown in the economy. And the delusion about the April rate cut when inflation was above 3%.
This is a 10-line example. In real-world code you will get a segfault and then have to hunt through the codebase with a debugging session to figure out where it triggered.
the people going here are actively jumping out of an airplane. they chose to do this and are well aware of the risks. is it dumb? possibly. is this some mad profiteering stealing money from millions and casually ignoring people dying left and right in some cold-hearted money-making scheme? absolutely not. disclaimer: i'm one of those dumb ppl who jumped at this place - quite enjoyed it. slow news day i guess.

Bullshit. The only reason to use Microsoft Office is compatibility with Microsoft Office files. What improvements have been made in the last 10 years in Outlook and Word? Nothing. There are some new bugs that didn't exist before, but no advancements. That's what lack of competition gives you.

The more people use free software, the more it will become cost effective to improve it using government funding.

There can be enormous net savings (zero license fees), which is fantastic for the taxpayer.
It's going to be really fascinating to see this applied instead of chain of thought and other kinds of reasoning approaches, because it's generic. It should in principle work on every kind of LLM.
Though this comparison is really only relevant for a couple of machines. Beyond that, at this cost, if you pay AWS list prices "at scale" you're doing something very wrong.

Don't get me wrong - I've frequently argued that AWS is price gouging and relying on peoples lack of understanding of how the devops costs of running your own works out, but it doesn't take a huge budget before this calculation will look very different (still cheaper to own your own, though).
Keeping it short: "Not even wrong", in the Pauli sense.

- People hear "mixture of experts" and they think "N specialists" - but ex. think how much know you need to know to autocomplete "Two plus two is "

- Fundamental thing of ML is you define functions and give it data, and the more data you give it to the better. Once youre at "I will simply give it the training data needed to be good enough at the task and wall off that part of the implementation" you're outside ML and have a chicken and egg problem

- We don't know GPT-4 is MoE

- MoE in practice is fundamentally about trading off runtime vs. static size properties to gain inference speed. I.e. 7x8 stored and picking 7x2 at runtime means youre somewhere between 7x2 and 7x3 in quality, inference at 7x2 speed, and have to train and store and load 7x8. You don't reach for it to increase quality, you reach for it to increase inference speed at the expense of inference ram and total model size.

I’m skeptical that established automakers even felt threatened. For one thing, manufacturers seemed to overestimate present demand for high-end, expensive EVs (no way Apple was going to build a lower-tier “economy” car). Also, companies just entering the automotive industry (Tesla, Rivian etc.) seem to face loads of challenges that long-lived ICE manufacturers have solved a long time ago.

Piratebay may not work as smoothly.

Content doesn’t appear effortlessly on all your devices. Some subtitle languages may be missing. Less mainstream content may be of low quality, slow to download or missing too. Plus, you have to plan ahead or wait for the download to finish. At this point I would double check the streaming plan price (as long as there is an ad free tier).
Hmm, well – Objective-C holds a place in my heart. It's not for everyone, but it's really where I got my start and I think it's a beautiful language and had an incredibly unique community around it that started with all the NeXT folks.

I'd be curious why Objective-C now? Still has its place for some things. It's interoperability with C++ for instance, especially if you're dealing with things like Metal or certain real time audio libraries.

It's also probably a niche in terms of maintaining legacy stuff. Like being a Fortran developer and having your pick of contracts because nobody remembers it anymore and some crucial piece of infra relies on it.

But, Big Nerd Ranch guid is how I learned! And again, by doing projects. Just pick something you want to build with it and see it through to the end. Like writing, it's best to plough through and just get SOMETHING that works end to end, knowing that it'll be your first draft and you'll get it better on the second Tim around.

Good luck!
No thanks, I’m just gonna go to the grocery store down the street where they don’t make me do linear algebra just to buy a box of Froot Loops.

Sequoia put out a PR piece about SBF [1] a few months before it all blew up, and it's pretty amazing, and has made it a lot easier for me to believe that VC partners are maybe not necessarily that smart:

> [Sequoia partner Michelle] Bailhe remembers it the same way: “We had a great meeting with Sam, but the last question, which I remember Alfred asking, was, ‘So, everything you’re building is great, but what is your long-term vision for FTX?’”
That’s when SBF told Sequoia about the so-called super-app: “I want FTX to be a place where you can do anything you want with your next dollar. You can buy bitcoin. You can send money in whatever currency to any friend anywhere in the world. You can buy a banana. You can do anything you want with your money from inside FTX.” Suddenly, the chat window on Sequoia’s side of the Zoom lights up with partners freaking out. “I LOVE THIS FOUNDER,” typed one partner. “I am a 10 out of 10,” pinged another. “YES!!!” exclaimed a third. What Sequoia was reacting to was the scale of SBF’s vision. It wasn’t a story about how we might use fintech in the future, or crypto, or a new kind of bank. It was a vision about the future of money itself—with a total addressable market of every person on the entire planet. “I sit ten feet from him, and I walked over, thinking, Oh, shit, that was really good,” remembers Arora. “And it turns out that that fucker was playing League of Legends through the entire meeting.” “We were incredibly impressed,” Bailhe says. “It was one of those your-hair-is-blown-back type of meetings.”

There's plenty of other stuff in there. It's not just pumping up a promising bet that went bad, it's hagiography on a scale that is almost impossible to believe, approved by an organization that is really supposed to know better.

This is what tools are.

Cheap digital tablets have done away with the need for expensive consumables. You can just download a different brush style instead of learning a physical technique. No waiting for paint to dry or smudged pencils. The barrier to entry for painting has dropped to a one time investment of like a hundred bucks. Almost nobody mixes their own paint, nor stretches their own canvas. Those skills aren't needed anymore.

It's possible to build very precise machine parts by hand. It's very difficult and requires great skill, so nobody does that. Some do and are admired for it, but everybody else uses precise machines to make precise parts with nearly no effort.

It's just a tool. Only difference is that we had assumed art would never be automatable.

Objectively, I don't think this is a bad thing. It doesn't change the subjective value of art any more than the average cartoonist devalues the Mona Lisa. It's just a new form of art, there will always be people mixing their own paints and stretching their own canvas, just as there always has been.

It's only a problem because in our society you either have a job or you starve. No one can afford to be an artist. Those that do tend to grind out as many pieces as fast as they can so they can pay the goddamn rent. If not for that, these AI tools would be pretty cool.
