I wouldn't count on it. Nvidia's been cleaning up shop, but their best option for expanding right now is through parallelization (bigger clusters, basically). Now that Blackwell is on TSMC, Nvidia is alongside Apple waiting for new and denser nodes to upgrade to. A real "generational leap" in training cost is going to require some form of efficiency gain that we're not seeing right now. It's possible that Nvidia has something up their sleeve, but I'm not holding my breath.

> What I think will be interesting is when commodity hardware can run cheap inference from very capable, specialized models.

What's funny is, you basically already can. The problem is becoming integration, and in the case of video games, giving the AI a meaningful role to fill. With today's finest technology, you can enjoy an AI-generated roguelike that is nigh-incomprehensible: https://store.steampowered.com/app/1889620/AI_Roguelite/

As time goes on, I really think developers are just going to not use AI for video games. Maybe I'm missing the "minecraft moment" for procedurally-generated stories here, but the sort of constraints needed to tell a story of create an interactive experience don't exist within LLMs. It's a stochastic nightmare of potential softlocks, contradictions or outright offensive requests. The majority of places I've seen AI applied today isn't for content creation, but instead automated moderation.
I don't think the price itself is the root problem. I mean don't get me wrong if it were $350 it'd sell a lot more than $3,500 but the point is it still wouldn't sell well anyways so why only ever talk about how it costs a lot.

To me the problem with the Vision line is it doesn't give any compelling reason to want it now or in the imminent future, even if it were priced similarly to lower end headsets, to really drive large numbers of sales on yet another VR walled garden. There is no killer app you'll spend hundreds of hours in, it's not going to actually replace/upgrade using your traditional apps, VR gaming is already relatively niche in established and open marketplaces but this has a brand new walled garden marketplace, and it offers nothing particularly "revolutionary" people haven't been promised 100 times about VR/AR to be disappointed with already. If it offered something meaningful against all of these points then it'd still sell decent numbers even at $3,500 but the problem is it's just lame despite being so high end.

curious why you think this?
How does the tobacco industry spread those anecdotes exactly? I find it a bit difficult to believe, seems like smokers would be able to spread them on their own just as well, as they provide stories to relate to when you can't quit.

I mean the actual AR experience, every other headset i've used is so janky and can't persist objects enough to actually immerse you. AVP windows I've actually attempted to avoid while walking because my brain forgets they aren't real after a little bit
JWST is a taxpayer funded science mission, and the science run on the observatory isn't a pay-per-use model. I don't think a second JWST available for hire would see anywhere near the demand JWST currently fields.
Yes, and it pays way more and is remote.
Apple is extending the monitor capabilities in their next software update, which at least to me is a good sign that they plan to keep expanding support for that mode.

I'm in the same camp as you – my main objective for a headset would be infinite portable monitor space. I really hope we get there in the next few years.
Run Functions in Another Stack with Zig
Every program compiled with a reasonable compiler runs putting some of its data in the so called stack. It’s fairly easy: when you call a function, the function puts its data on top of the stack; when the function returns the data is removed so that the stacks now exposes the data of the caller function. In this post we mess with this mechanism, but substituting the default area of memory for the stack with a freshly allocated one.

The hubris of Apple thinking people would buy a $3500 USD VR/AR headset.
Oof, no. I'm well aware of the advice and I don't agree with it.

I expect GME to crash and burn. I was going to change jobs at some point, in which case my traditional 401K funds will just disappear because they are not vested. If I happen to win the blue moon GME lottery I'll just stay a bit longer to vest the winnings. In my specific situation it's essentially buying memes with someone else's money at zero downside.

As for BTC, I don't use Roth 401K/IRAs as a retirement vehicle. I use it as legal tax avoidance on a very specific high-risk part of my portfolio that is tax-inefficient if it wins. Given the shitty 401K dollar limits I'm not going to put a cent of it toward stuff that's already tax-efficient if I have tax-inefficient stuff outside that can be swapped in.

The vast majority of my net worth is {municipal bonds, index funds, stocks} are all held in a normal brokerage account because they are not taxed as much to begin with. That's my actual stably-growing retirement fund, and much, much larger than my 401K.

This isn't investment advice, but if you are in a job where you are maxing out your 401K but saving much more outside the 401K than inside it, I'd encourage you to consider the math of doing all your index funds outside 401K and whatever high risk plays inside 401K/IRA. You may find the math works out better that way, like I do.

Heh, basically the opposite for me.

I switched to linux in 2008, Ubuntu on an HP laptop. For the most part it "just worked" and I never really needed to edit the X configs, but I do remember fiddling with them occasionally for some reason. I think it was for some peripheral or other (like a mouse, when I usually used the touchpad).

Generally at the time I'd only see this backround if I was experimenting with my window manager and it crashed. Ubuntu was using Metacity at the time, and I'd switched to Beryl and was going wild with customizations. And when the window manager crashed and all I had was that and windows I couldn't move, I had no idea how to recover and had to hard boot.

I'm fairly sure Ubuntu was hiding this on startup already at that time, if not very shortly afterwards.

I doubt developer relations have anything to do with this at all.

There's no users, no plan to scale to lots of users, and therefore no developers.

It might be partially because of the size of the VR/AR market, but Apple's approach with Vision Pro was never to try to capture all of it. It seemed mostly to gain experience in manufacturing and start to see if anything actually materialized.

In many ways it's a very anti-Apple product launch in that it didn't have a very clear use for the common person from day 1, which has been the mantra for everything from the iPhone to AirPods.
> For example, video game space has already been trying to create AI-powered NPCs, world generation and story-telling (e.g. Inworld AI).

Current AI isn't even close to good enough for video game NPCs and related. We're several breakthroughs away from that being possible at any cost. Those breakthroughs might happen in 3 years, or they might not happen in 10. Hard to predict.

I am utterly impressed by the logic of this argument.
> Once in orbit, I start accelerating until my clock ticked faster

Note that this is wrong: you don't have to accelerate to make your clock tick faster. You just have to be in orbit at a high enough altitude for the speedup due to altitude to outweigh the slowdown due to your free-fall orbital speed.
> Are you serious? This should be 1, max 2 instructions, with no branches and no memory use.

Sure. ---> One could add two fixnums and get a bignum.

CL-USER 31 > (fixnump (+ MOST-POSITIVE-FIXNUM MOST-POSITIVE-FIXNUM))
NIL

As you see here, adding two fixnums can have a result which is not a fixnum.

Yes, Common Lisp does by default determine whether to return a bignum or fixnum.

The machine code you've shown takes care of that.

Let's see what the SBCL file compiler says:

CL-USER> (compile-file "/tmp/test.lisp")
; compiling file "/tmp/test.lisp" (written 11 JUL 2024 10:02:04 PM):

; file: /tmp/test.lisp

; (DEFUN FX-ADD (X Y)
; (DECLARE (OPTIMIZE (SPEED 3) (SAFETY 0) (DEBUG 0))
; (TYPE FIXNUM X Y))
; (+ X Y))
; --> SB-IMPL::%DEFUN SB-IMPL::%DEFUN SB-INT:NAMED-LAMBDA
; ==>
; #'(SB-INT:NAMED-LAMBDA FX-ADD
; (X Y)
; (DECLARE (SB-C::TOP-LEVEL-FORM))
; (DECLARE (OPTIMIZE (SPEED 3) (SAFETY 0) (DEBUG 0))
; (TYPE FIXNUM X Y))
; (BLOCK FX-ADD (+ X Y)))
;

;
; compilation unit finished
; printed 1 note

; wrote /tmp/test.fasl
; compilation finished in 0:00:00.031
#P"/private/tmp/test.fasl"
NIL
NIL

Well, the SBCL compiler does tell us that it can't optimize that. Isn't that nice?!

If you want a fixnum to fixnum addition, then you need to tell the compiler that the result should be a fixnum.

(the fixnum (+ x y))

Adding above and now the compiler no longer gives that efficiency hint:

CL-USER> (compile-file "/tmp/test.lisp")
; compiling file "/tmp/test.lisp" (written 11 JUL 2024 10:03:11 PM):

I'm not sure that's right. Apple launched the watch thinking "apps like iphone"

A few versions in, they settled on "watches are for health and fitness"

Ben Thompson discusses the AVP as an immersive iPad, and that's kind of the problem. It's too locked down to be my productivity device (something that could justifiably command a premium price), and my entertainment budget isn't that high for one person (I already have a tv in that price range - cheaper tbh - that's really really good)

Anyone that has been following VR/AR headsets for the last 30 years was already expecting this.

How come does Apple come to a market that was already going down, pretending that Quest and HoloLens never did developer sessions showing exactly the same kind of content, a decade ago?

To make matters worse, their current attitude that developers should feel grateful and blessed to even be able to touch their SDKs, means that very few feel like targeting a device that costs as much as it does.
Mental health research feels silly to me. When humans are put to live in small apartments and pushed their entire lives to obey the BUY and VOTE commands, they will of course go insane. It's questionable whether anything can be done about this but those who live in the illusion that there was no complete behavioural control of the average homo sapiens and use false models of the causes of the mental issue problems, that somehow do not go after the socio-political root causes IE judge the abusers, not only betray themselves but those who they seek to help the most.

To englighten: Smartphone could be the most useful cognitively beneficial, amazing tool a children can have. Your own photography, recordings, books, and all your friends available to call on a single device is plain wonderful. But the smartphone, the PDA, has been made a tool of surveillance and manipulation. The average parent does not comprehend the problem or have any technical capability. Children usually are directed to fitting in socially. If nothing else, the children will watch Youtube videos on their friends phone and soon start to idealize them, else you will not know what the other children even speak about, when they have been manipulated to worship a brand or to support some political agenda indirectly. They will not be able to cut all the harms out of it.

World has three classes: owners, hermits and pets. Because majority homo sapiens belongs to the lowest class, the species tolerates most animal abuse out of primates.

Apple has definitely, definitely soured their relationships with third party developers— but I think the far larger issue is the install base. There isn’t enough AVPs sold to ever recoup the cost of developing a VisionOS native application.

There are also effectively 0 well qualified developers for VisionOS — it’s so new that no one outside Apple has a significant amount of experience. So even beyond pure build hours alone, getting an application launched on the platform is a non-trivial amount of developer training.
I don't see what is so appealing about backwards compatibility. The database is an implementation detail and its specifics should not block anything.

Seeing several comments like yours is puzzling to me because I find myself unable to understand what are the devs preaching for it gaining from SQLite's extremely conservative backwards compatibility policy.

For example, PostgreSQL has `pg_upgrade`. You run that after you upgrade its major version and it's a bulletproof and easy transition 99% of the time.
One downside of rolling it into an IRA is that you'll pay more in taxes to do backdoor roth IRA conversions every year. I think it's better to leave it in 401k if the fund options / fees are acceptable.

I didn't like it because I hated getting interrupted after 25 minutes. It kept breaking my focus.

What I found worked well for me instead was "count up" pomodoro.

- Start a stop watch or simple wrist watch and leave it on your desk.
- If you glance at it and it is less than 25 minutes, keep going.
- Else if it is over 25 minutes, take a break if you feel like it. Write down how much time you worked. At the end of day, add up your time.

Although it is probably good to set a timer when taking a break because you do want to be interrupted in that case.

No surprise here. Labor costs in CA, NYC, and other HCoL areas are driving this trend. It started with self-checkout and ordering kiosks, and this was obviously where it was going to end up.

I wonder what this will do to fast-food and fast-casual prices in the medium- and long-term. Will it ever result in price drops, as the technology is commoditized and rolled out at scale? Or will it only slow the rate of increase, as machines are swapped in as a substitute for the least economical human labor?

Apple’s issues with the EU/etc have nothing to do with it.

Apple has a hard core base market. That said, the Vision Pro/headset market is small and Apple is only really going to get the Apple fanboy portion of that.

I've got a Quest 3 and I have to say I thought the Vision Pro interface was about 100x better. Windows stay concretely fixed in place (instead of skittering and jittering about), and the interaction paradigm required no training and worked flawlessly for me. Every time I pick up my Quest now, I feel the disappointment of having to use a controller or the terrible hand tracking.

> Truthfully, you're probably just doing it wrong if you can't derive actionable metrics from logs

I have ~200 services, each composed of many sub services, each made up of a number of processes. something like 150k processes.

Now, we are going to ship all those logs, where every transaction emits something like 500-2000 bytes of data. Storing that is easy, evne storing it in a structured way is easy. making sure we don'y leak PII is a lot harder, so we have to have fairly strict ACLs.

now, I want process them to generate metrics and then display them. But that takes a lot of horse power. Moreover when I want to have metrics for more than a week or so, the amount of data I have to process grows linearly. I also need to back up that data, and derived metrics. We are looking at a large cluster just for processing.

Now, if we make sure that our services emit metrics for all useful things, the infra for recording, processing and displaying that is much smaller, maybe two/three instances. Not only that but custom queries are way quicker, and much more resistant to PII leaking. Just like structured logging, it does require some dev effort.

At no point is it _impossible_ to use logs as the data store/transport, its just either fucking expensive, fragile, or dogshit slow.

or to put it another way:

old system == >£1million in licenses and servers (yearly)

metric system == £100k in licenses and servers + £12k for the metrics servers (yearly)
It's more that VR/AR is a high-cost solution still in search of a problem that makes it profitable.

So far the only market for VR is niche entertainment. VRC is fun, but VR games have been arounds for decades and never gotten past novelty.

AR has value as an accessibility tool because it can get around the high cost of some infrastructure changes. But like all accessibility tools, profit-focused eyeballs see it as a small, low-margin market. Enabling human rights is not considered profit.
