Let's say you are committed to AR/VR research. It's expensive. Let's say your research has generated tech that can be built into $2500 headset. You still have a long road to get better tech into a lower price range.

Then somebody proposes that you sell 100,000 of what you have right now for $3500. This provides $100 million dollars of profit to offset your research costs. In the end, you manufacture 80,000 and sell 60,000 of them. So you net $10 million plus 60,000 free testers (well, 1000 after everyone stops using them at all) plus 20,000 surplus units to use in various research.

Gizmodo can paint this as a commercial failure. Apple could sell the 20,000 unsold units for $100 each. That would generate another $2 million of profit even at a $2400 marginal loss per unit. They would fly off the shelves and Gizmodo would paint this as a huge commercial success. Even though Apple still wouldn't hit their 100,000 unit target. It would create panic in Apple's competitors even though they actually make a profit on $500 headsets.

So read this however you want. It's a commercial failure because it only netted $10 million dollars and might only net $1 million/year going forward. Or it's a successful funding round on the road to cheaper and more capable future products.

I'm not particularly an Apple fan, but I think it's silly to portray this in such a bad light. Would somebody like SimulaVR love to experience such a "failure"?

(All numbers above except the 100,000 target units and the $3500 price are hypothetical.)
For sure it did make me healthier and know my body better

In order to run your MC simulation, you'd need a model for your start-up's success. I have no idea how to do it, maybe there's something you could do with the funding part (simulate interest rates and something like that), but in the end you'd end up with a model that probably would not say much about reality. Then you'd run the simulations and get results that at best would be worthless and at worst harmful.

I don't know if VCs do it, but I'd hate to have the funding for my company blocked by some shitty model that I would have had to game in order to get the dollarybucks.

Then it won’t be a success for another ten years. You can call them unrealistic expectations if you’d like but I’ll drop thousands on a laptop because I use it day in day out. There’s simply no chance I’ll be doing the same with a Vision so the price I’m willing to pay is adjusted accordingly.
Right, $3500 is a really clear signal that Apple knows what it's doing, that this is not even an attempt to be a mainstream product yet.

Who knows if they'll succeed in the end, but this is just the beginning of a long term project.
My understanding is the root weave is a pattern designed to be hard on your monitor(a crt when it was designed). It is ugly as sin but that tight flip from black to white was intended to expose any weakness in the driving beam, ether from misconfiguration or components failing. Where another pattern may obscure the problem. I think it is also rough on lcd's where a misbehaving one really sparkles on the weave.

I am not sure why it was the default, I suspect it was to give you a chance to see how your monitor was behaving on a fresh install and you were expected to set the background to something else.. I still run the root weave on my desktop, it is obsd with their xenocera where it is still the default. but I also run a tiling window manager so only actually see the root window once in a blue moon.
> Yes, I think it has some good uses for health/fitness. I can't bring myself to think it is the driver for people buying it.

I think you're just mistaken, then. Health and fitness absolutely is the driver.

They tried to market it as a fashion purchase in v1, and then gave up on that. It can still be fun with different straps, but I don't know of anyone who considers it a fashion purchase.

That’s algorithmic complexity/“difficulty”, and somewhat assumes that we only care about computers solving the maze.

Since solving mazes is however (also) something to be enjoyed by humans, it’s possible that perceived maze difficulty could be dependent on factors that wouldn’t really matter for a straightforward algorithm. For example, a very “jagged” maze could feel more difficult for humans because it’s harder to follow with your gaze, while an optimal maze solution finding algorithm wouldn’t be impacted.

In cases like this, formulating difficulty can be more of an art than an optimization problem.

EDIT: See also andrew_eu’s reply (which I only saw now), where multiple “interesting” notions of “difficulty” are proposed.

EDIT: Relatedly, humans use heuristics a lot. And there are many NP-hard problems where we can solve lots of “reasonable” points in the problem space in reasonable time (computers or humans alike), at the risk of having to time out, maybe try with another approach, and eventually just give up. Traveling salesmen are actually traveling the country after all. So worst case is not always a good measure for games. But I see you mentioned that already.
Are we sure "OS" here meant "open source"? I read the comment you are replying to as "operating system"--particularly within the context that the project being discussed is Mbed OS--and when I started reading your reply I had to do a double-take as I found the wording "if it's [Operating System]" extremely confusing.
It is certainly possible that this particular improvement isn't hugely relevant to you. However this is well beyond "it's nicer" -- it has been a game-changer for me, and the core ideas Jujutsu is built out of result in many such improvements across all kinds of workflows. And I want to emphasize again that this is not contrived; it is how I actually did some work recently.

But also, tools shape our behaviors. Your current workflows are influenced by how Git works, and it's quite possible with Jujutsu you'll change your workflows. Maybe in a direction that you'll like more in the end.

Honestly we should just abandon all that bullshit and just use TAI for internal representation. Would probably save billions.
With modern security measures that’s definitely a thing of the past. If Apple intentionally adds bugs it will be mostly used to make spyware so they can’t do that anymore
Map_shared and RSS/SHR
Recently our team at Databento was debugging a memory leak on an experimental debugging branch. For context, this is on a Rust application that distributes billions of market data messages per day and we're using shared memory/mmap queues for interprocess communication. It turned out to be a false alarm due to adding tokio-console to a component.
The second half of the article deals with the evolution from a 1964 mainframe game to a simplified version that fit into 4k of FOCAL on a PDP-8, and then to the BASIC version found in David Ahl's well-known "BASIC Computer Games" books under the name "Hamurabi" (with one M).
It's a shame that we entered the era of precision a century or so before we got some good science.

We could have chosen so many different, cooler distance units than "one ten-millionth the distance between the North Pole and the equator, on a line passing through Paris". We could have chosen 1 nano-lightsecond! We could have chosen the wavelength of the hydrogen line! We had options, but we didn't even know them in 1800.

Avogadro's number is about 3% off from 24!. Instead of defining our mole as the number of carbon-12 atoms equal in weight to 12 cubes of water each one-billionth the distance between the North Pole and the equator, on a line passing through Paris, on a side, we could have defined it as 4!!! Imagine telling that to aliens when explaining our standard units, they'd be so jealous they'd convert on the spot.
Wow, it sounds like the quality of employees at the Apple Store has really taken a nose dive. I could never imagine anyone who worked there saying something like that in the past.
She details what happens.

> I lost count of how many people were harassed for following me on Instagram and reported unfollowing me out of fear. They even looked up followers’ employers on LinkedIn. I had to delete all the online photos where I appeared with friends. Pages replicated my name with the adjectives transphobic, racist, and even Nazi. Death threats flooded my inbox, always graphic, with much hatred directed at my vagina and my mouth, calling it “dirty pussy” and worse, threatening to “cut your tongue, take out your teeth”. The profile of the gallery that represents my artwork was sent countless messages, with artists asking for my work to be burned or at least for the gallery to stop representing me. They flooded my daughter’s Instagram profile too.

> People threatened others via inbox if they had anyone among their followers who still followed me. Curators threatened artists, artists threatened curators, and negotiated curatorial and art texts written as payment for the heresy of having given me a supportive “like”.

Then she lists some of the consequences of this harassment:

> While I don’t receive as many threats today, the invitations for projects have dried up. Jobs in the art world are rare, if not non-existent, and associating with me seems to be considered criminal. I keep trying to hold my head high, but it’s increasingly difficult.

> After everything I’ve given to art, I now find myself unable to invest in my daughter’s education, the one thing my family did for me. It breaks my heart. It hurts even more to know that, for her safety, she denies being my daughter when asked on the street.
I think I remember reading somewhere that electric planes would have a much lower energy density than liquid fuel, making its utility minimal. How does hydrogen-powered flight compare regarding energy density?

Yeah, I don't get it. Ads are apparently quite expensive if you're a legitimate author -- but there's an ocean of total nonsense ads for books that I can't even find via a regular Amazon.com search.

Could it be that they're filler generated by Amazon to make your ads more expensive? What other explanation even makes sense?

Slightly off topic -- I just saw people saying how Mac's unified memory makes it a strength to train models on Macs: https://www.macrumors.com/2024/07/10/apple-leads-global-pc-g..., and how energy efficient they are etc. But what I am seeing is that people don't often even touch Macs at all -- they write code with CUDA and that's it. I find this kind of conversation fascinating.

AVP is incredibly expensive but Meta makes a consumer friendly budget option for $500 and that’s not selling crazy well either.
Is it crowd noise or just a gap? I'm also interested to see one of these skipable crowd noise CDs.
$500 is what a new gaming console costs. If Apple wants to compete for the attention of people with better gaming/entertainment experiences then their price needs to come down.

I think it's unrealistic of Apple to expect sales for more than $500, and the market has proven that to be correct.

They did not. There was all sorts of speculation and enough circumstantial evidence to implicate either Russia or Ukraine or the US depending on what your threshold is.
The author of Syncthing-fork has actually said they've had similar problems with Google and believe it's only a matter of time before their app is locked in a similar way - so much so that they are planning to surrender their Play developer account:

I think it's pretty optimistic to expect either of those will be realized in a couple of years. If Apple does release a v3 in that time (big if), I'm doubtful it will amount to more than a minor iteration on the first gen model. I think Apple is probably happy to let this stay a niche product with a very slow release cadence.

After all, why would they release a v2 next year? What significant improvements could they make in that time that would entice new customers - or entice existing customers to upgrade?

The MacBook is a work device used by many professionals and can easily be justified as a recurring business expense. The iPhone is a relatively cheap device whose sales are bolstered by affordable payment plans offered by US carriers. These devices sell in huge volumes and it makes sense for people upgrade them often, so there's a lot of money to be had in frequent iterative releases. That's just not the case with the Vision Pro.

If Apple releases a new Vision Pro, it will need to be a big upgrade - or a cost-down model with a more accessible price point.
Zero mention of what a RAG is on the README. No clue, here.
> Are you sure?

Absolutely.

Current LLMs have insufficient world state. Imagine a game like Stardew Valley. It's got a town with 30 NPCs or some such. They all have personalities and the player builds a relationship with them over time. Current LLMs can't do that. They hallucinate waaaaaaay too much. You can't reliably define and evolve relationships. Amongst many other short comings.

I'm super pro AI and use ChatGPT all the time for programming. So I'm not being an AI hater. But I am a gamedev and I can say that what exists today simply isn't good enough.

Good! Instead of using bulky and slow web frameworks, it's time to build native applications again.
Does this work my running LLM such as Llama directly on the database server? If so, does that mean that your database and the LLM are competing for the same CPU and memory resources?

Yea ~10ms is my experience using localhost TCP, using a Unix socket would probably be faster.
Then you know how crazy expensive it is to have to mount one or more monitors above you, hanging from some kind of support.

And like I said, isolation while working is actually kind of a feature, when you're deep in productive work. Just think of all the people who wear noise-cancelling headphones in offices to tune out the distracting environment.

I don't want to use it for video calls or while multitasking, but for serious work I want to be isolated -- that's a feature not a bug. And passthru is a kind of nice in-between mode.

I used to work in game dev ~9 years ago. iPhone is where the users are, so naturally that's your main target. But your game will accomplish success only if you're featured in the app store (I don't own apple so this might have changed drastically). But in order to get featured...

Haptic feedback in the newest iphone? You need to support it in order to be featured.

You can play games on apple watch? If you support it, a guaranteed feature.

New localisation guidelines? Featured only if you support all of them.

So back then (not sure how it is right now) you needed to implement useless or at the very least something unnecessary in order to be featured on iPhone and make a buck. Otherwise apple wasn't able to sell their new technologies.

If nothing has changed, people will try to port their games to apple vr so they are more likely to be featured on iPhone.

All our games (6, iirc), were featured.

Arena-Learning: Build Data Flywheel for LLMs Post-Training
I'm interested, but am waiting for v2 or v3. At this point it's already been out for 6 months, so what's another 6 months in hopes of a smaller/lighter version with a slightly lower price point, not to mention more apps and content. Reviews haven't been strong enough to make me think I'm missing out on much with the v1.
You’re formulating the problem with a lot of implicit assumptions. That is ignoring a lot about how human visual perception works.

Look at a very simple maze, you will likely “intuitively” solve it immediately without performing an actual DFS. Implementing that as an actual computer algorithm would be insane since your algorithm would now rely on the computational needs of a human perception system, which decreases algorithmic efficiency by many orders of magnitude. But humans with their weird squishy brains have what they already have, and on the flip side are simply not optimized for algorithms on all but the smallest data structures. (You can very easily read even distorted text, but you have an extremely hard time balancing a simple red-black-tree in your head or even on paper.)

EDIT: Relatedly, humans use heuristics a lot. And there are many NP-hard problems where we can solve lots of “reasonable” points in the problem space in reasonable time (computers or humans alike), at the risk of having to time out, maybe try with another approach, and eventually just give up. Traveling salesmen are actually traveling the country after all. So worst case is not always a good measure for games.

You could maybe pull this off in a game like Borderlands where the loot is basically just the same dozen guns but with different numbers and effects. But as is, the LLM text isn't going to be much different than a sufficiently large AdLib system.

I think there is value to be gained in having LLMs as part of the development process, maybe even the game itself, but I think conventional methods are about as sufficient for quests.
may I ask if you have any career advice?

If you'd like to hold CNN accountable for saying false things, then you should also want people to hold you accountable for saying false things. CNN never claimed knowing it was Russia, feel free to source that claim. Therefore, every time you post something related to the media online, people should pop in to say jasonvorhe was wrong about what CNN said and isn't neutral, right?

Personally, I understand that serious media orgs may get things wrong sometimes, but are generally criticized and held accountable for their errors, while any criticizer and alternative media can spew falsehood after falsehood and no one bats an eye on their future claims.
Thats so great to hear, glad that you got out of that toxic environment.
