Because if memory is a big array of bytes and pointers are indices into that big array, that should be numerically valid. And indeed, if instead of making xs and ys separate arrays, one writes:

int zs[20] = {0};
int *xs = &zs[0], *ys = &zs[10];

then no perplexing behavior is observed.

Of course, any veteran C programmer will point at that being UB, but the big-array-of-bytes (with holes) model is what one sees in userspace assembly, and what I assume most systems programmers think about most of the time, rather than the C memory model.

I wouldn't recommend that someone trying to learn systems programming (as opposed to C or C++ as languages) spend, like, any time whatsoever memorizing the list of C UBs (and then learning about pointer provenance, exposed addresses, etc., I suppose?). Assembly, Forth, safe Go, and safe Rust don't have the same kind of UB, and (Linux) kernel C has a different set of UBs than userspace/spec-compliant C.

The physical experience is not the same, and the software experience is also not the same, a dedicated device would give proper signal to game developpers to make/target/re-release their premium games, rather than designing games to be played for few minutes on a touch screen

That kind of accessories usually map physical buttons to touch inputs on screen, not idea

Similar to movies, that's not because you can watch movies on your phone that you'll want to watch all your movies on your phone, a dedicated device is often what you want

As an adult this is me and my friends, I don't see a problem with it. It's not like we're ignoring each other. I'm not sure why everyone is so hostile to kids having internet. I grew up watching YouTube and browsing Reddit on my phone too, that hasn't hurt me any.

For the past 5 years or so, it has gone in spurts for me: no time in VR for months (sometimes even a year or more at a time), then nearly all my gaming time is in VR for a couple months or so.

Since the PSVR2's release, when I hang out with one of my friends, I play one of his VR games almost every time I'm there. That undoubtedly won't last forever, but it definitely has the best launch library of any headset so far IMO.

Maybe I'm just a really picky gamer, but for any given console generation, there are only a handful of games I truly love, but it's easier to enjoy a fine but not incredible game on a flat screen than it is in VR. A really good VR game makes you forget about everything else and gives you an experience unachievable outside of VR. If you're immersed in a story, a song, or intense gameplay, you forget about any discomfort coming from the headset being on your face. But if you're not enjoying it then you're going to get annoyed a lot faster than you would sitting on the couch looking at a TV.

That said, the PSVR 2 is looking to have the best library of VR games yet. Previously, you'd have incredible one-off titles such as Half-Life: Alyx release on Steam but then nothing for months or years, but Sony seems really committed to providing a large number of high-quality AAA experiences on the headset. It also has a ton of great games from smaller studios (most of which were already on Steam or the Quest, but with such big libraries on both of those platforms, they were kind of tough to find throughout all the mediocre titles: this isn't an argument in favor of stronger curation, just an observation.)

Nonetheless, I don't expect it to make up the majority of time someone would play video games anytime soon, and there are two reasons:

1. Most people don't have VR headsets yet, so even if I personally prefer Pavlov to other FPSs, only two of my friends have VR headsets, so it's not replacing those flat screen games. Maybe one day, but currently the most popular games run on nearly everything: Fortnite, Minecraft, Apex, Overwatch, CS:GO, LoL, DOTA2, Valorant, Rocket League, etc. I doubt those games' popularity stems entirely from the fact they're on tons of platforms OR have very low PC requirements (or are free to play, minus Minecraft), but it likely helps.

2. Nearly all VR gamers play flat screen games, but the majority of flat screen gamers do not have VR headsets. The Quest 2 may have sold around 20 million units, but nearly all of those owners likely have a Switch, PlayStation, Xbox or gaming PC. Medium-sized studios certainly are incentivized to create VR games due to less competition (getting a game released for PSVR2 nearly guarantees at least some sales, unlike releasing on flat screen), but large studios with huge marketing budgets looking to make a ton of money can make more by selling flat screen games. Maybe they'd get some additional sales by releasing it for VR, but it's not guaranteed (hopefully it becomes more profitable to port to VR as the number of users increases though.)
I sit on a reclining desk chair, about 4 feet back from a 46" TV. I have a lap desk with a bluetooth keyboard and trackpad. Love it! I'm interested in trying this out, to be able to have a bigger screen, and to be able to take it anywhere.
Qualcomm's processors aren't really comparable to the Apple Silicon ones. They haven't made anything like an M2 Pro/Ultra.

I'd also say that Microsoft isn't "pushing" for Windows on ARM. Rather, they're adding support for Windows on ARM with very little weight behind it.

This is where things get into a chicken-or-egg problem. There's no reason to buy a Qualcomm/Windows ARM laptop given that an Intel laptop will perform a lot better, have better compatibility, and not have to emulate x86/64 for all the apps that developers won't port to ARM. Given that there's little reason for someone to buy an ARM laptop and only 1 of those reasons is under Qualcomm's control (making a better laptop processor), there's little reason for Qualcomm to make a better laptop processor. Given all that, over the medium-term (say, 2-5 years), there's little reason for Microsoft to devote a lot of effort to Windows on ARM.

When Apple introduced M1, they gave users a chip that was way better than what Intel was offering. It was night and day. Everyone knew that there wouldn't be Intel Macs in a few years so we all bought ARM Macs and developers ported things to ARM (as users knew they would). By contrast, no one in the Windows world is betting that ARM is the future of Windows - not users when buying, not developers when compiling, and not chip makers when making processors. Without commitment, there's little chance for success and no one is willing to truly commit.

If you want Linux on ARM, you can go out and buy a Pinebook. The problem is that you aren't getting a flagship CPU. You're getting mediocre 2016 hardware. Even if you got a Qualcomm 8cx Gen 3 meant for laptops, it's half the speed of an M2 (regular, not Pro or Ultra) and slower than what Intel will be selling you.

The problem is that the options for non-Apple ARM laptops are just poor. Even if you could get the best Qualcomm has to offer, you wouldn't buy it because you could get a better Intel machine - and not have to deal with compatibility issues and emulation. Sure, Windows on ARM can run x86/64 code, but there are always things that don't quite work or work very slowly or chew through RAM or battery because you're on Windows/ARM and no one is expecting that.

You can run Linux on ARM today, but there just aren't ARM machines that are compelling to use that aren't coming from Apple (save for some stuff like the Raspberry Pi).
That's quite embarrassing. I personally am happy that my favored candidate has won in the end.

People need to stop using this horrible tool. I have watched people doing things in Excel in seconds for stuff that would take me multiple minutes. Main difference is me checking if results after each transformation are plausible. I wonder how often such "Excel-Errors" led to wrong decisions.
Because it is a non-argument. The implication is that engineers are incompetent and will never gain competence. There's much more detailed arguments to be made, but I'll give you two things to consider that will give you context and help you track down those arguments if you are interested

1) RBMK reactors (like Chernobyl) have a positive void coefficient, which leads to an increase in radiation as steam pressure increases. At the time of the of the disaster, this was generally considered "not a good idea" due to the ability for these reactors to explode and release high amounts of radiation. This was even known by Soviet Scientists and was even a plotline in the HBO miniseries (people seemed to miss this, but maybe a priori knowledge made it more significant to me).

2) Concerning Fukushima, the region was hit with the largest tsunami ever seen in recorded history for the area and one of the largest ever recorded anywhere. Meaning the largest to hit Japan in at least 1000 year. With the reactor being built in a time where scientific knowledge did not know that this magnitude of an earthquake was possible in such a fault. The comment implies that such lack of knowledge, and thus potential for danger, will always exist. But the knowledge even advanced before the quake happened, but was still relatively new at the time (btw, this also applies to the Cascadia subduction zone off of Washington and Oregon).

These were due to two completely different causes, with 25 years of experience between them, and with the latter being caused by an extremely rare natural disaster. It is improper to characterize risk by black swan events (or gray swan events, which may be more accurate concerning Fukushima). Additionally, the results and causes are not even remotely similar. The connections are simply that both involve nuclear power. It is literally comparing apples to oranges, which both happen to be round fruit that grow on trees. The argument is setting an impossible standard and using a false narrative. It is posting with high confidence but low expertise. In the end, it only confuses and makes it more difficult for anyone reading to acquire accurate knowledge about the events and actual risks of nuclear energy.

I had closed eye visuals on 2C-E where I saw microscopic fractal machinery that made up the universe. This was over a decade ago, so don't really remember the details. Should have wrote a trip report.
I have used a quest 2. It was… fine. It’s pretty charitable of you to say those screens aren’t a problem anymore, though. Still had screen door. Still made me feel a little unwell. Did it even do pass through? I seem to remember some awful grainy video feed.

We all have different standards though. Some people are already saying the Apple Vision screen isn’t high enough resolution either. Granted, none of them have gone hands on so I’m not sure what they’re basing that on.
You can equip 24GB RAM now, no?

Apple already outclasses everyone in throughput & throughput/watt especially. In case it wasn't already crystal clear, I was talking about everyone else finding ways to get their throughput up to more competitive levels, such as by supporting GDDR.
I wouldn't read that deep into it, they used the same types of homes in the same announcement video for the Apple TV ($100) section. It just looks nicer to the marketing folks.
This is not a VR headset. AR means you can seamlessly interact with your local environment without taking off the headset.

Even though I have two kinds of cons cells (regular and lazy) as well as the ability of objects to implement car and cdr and then work with those functions, I'm still fairly reluctant.

I wouldn't want source code to use objects, but real cons cells. Objects are heavier-weight. Each object is a cons-cell sized object, plus something in dynamic heap.

There are print-read consistency issues. Lazy conses and regular conses are indistinguishable in print. If you print some lazy conses, and read that back, you get regular conses. Of course, an infinite list made using lazy conses will not print in a readable way, so we can sweep that under the rug.

Objects implementing car and cdr have arbitrary print methods too. They won't print as lists. Those programmed to print as lists won't have print-read consistency.

It's priced just like Microsoft's Hololens and aimed at the same target audience that the first version of Hololens was: developers and early adopters.

The cheaper mass market consumer version comes later. They've been iterating for years now on something in a thick framed glasses form factor, and haven't gotten anything they think is worth shipping so far.

Apple has never always been about what only Apple can do, but asking like "What could the world be?" So the vision pro is maybe the first exciting VR product to come out in years, in that it's not just a headset, but an entire computing platform as well. We'll see whether they fixed the screen door effect as well as the nausea.

Does anyone else remember when apple released a 640x480 digital camera?

https://en.wikipedia.org/wiki/Apple_QuickTake

It was shortly overshadowed by the Canon D30 and the Nikon 70D. Both camera systems pretty much went on to dominate the digital camera world just a few years later.

But for the time being, I hope the Tilt5 still does well.
I could get behind this, but only if my kids had open access to the internet via some other device. Phones are addicting and can be harmful (esp to younger teens), but it is crucial that young people have access to the resources the web can offer. It opens up opportunities and allows teens to find support resources when their family/school isn’t enough (LGBTQ+ kids in states like Florida come to mind).

The biggest reason I have found success in my career field is because I had such a head start on those I went to college with. I got into software development in middle school, and was in frequent communication with other people building software (who were significantly older than me). Most parents probably would have shut this down. My parents let this activity continue, and it turned into my career. The relationships I built then and the lessons I learned have been invaluable. This experience was only possible because I had unrestricted access to the web. My kids, once they are mature enough to handle that responsibility, will enjoy those same freedoms.
> Do you participate in either or both of those markets?

My wife is a big 4 consultant (international tax). She has worked in almost all of them - E.Y, KPMG etc. Same structure everywhere - a couple of 35-45ish (sometimes 50ish) partners and a bunch of young managers and seniors who do all the work. My wife is now an old 36 manager there. So it seems like you either move up or move out in big 4.

> I myself would vastly prefer age and experience in a lawyer to the billable hour vigor of youth.

I have no argument with you there. I also tend to prefer older devs but it's a personal preference. Anyway we should try to move from an anecdotal discussion.

"According to the SRA, only 8% working at larger law firms are aged 55 to 64, and while the current war for talent has meant law firms have focused on attracting and retaining lawyers early on in their careers, we rarely hear about efforts to recruit and retain older lawyers."

> If you are actively preventing evidence of your actions from being created, that is itself evidence of consciousness of wrongdoing.

Government people are humans too, not just nameless bureaucrats. Imagine working somewhere that you would never be able to make a joke, speculate on a topic, ask a question, because it could be taken out of context due to everything being documented/written down.

It is fine to desire that, but realize that there needs to be a significant pay increase and/or a significant realignment of expectations, since nobody would want to independently take responsibility or action on anything. I have worked in a culture like that and let me tell you, it was extremely difficult to have every move under a microscope 24/7 and I would never do it again.
Not sure where you've worked but in my experience based on established finance firms, a scale-up and FAANGs, layoff-rounds - especially early ones - have a high mix of low and borderline performers.

Being in that cohort obviously hurts you - though obviously nothing is guaranteed.
Which has the really annoying side effect that now you actually need to produce a worse query to get decent results.

A few years back I used to scoff at people who wrote searches in the form of literal questions instead of boiling things down to key terms, e.g. the "how do i..., what is the largest..." type searches.

Nowadays I not only need to write stupid searches like this to get better results but quite literally find that my brain has adapted the pattern and my past skill at crafting salient key term, operator driven queries is eroding.
I mean it's not skimping, it's right at the limits of our technological capability. VR is weird in that once you cross a certain pixel density, no further improvements will matter because the eye won't be able to resolve the image better. But until you get there, it's much more limited.

The cross-over point AFAIK is about a 16K screen resolution (per eye) - i.e. at that point a screen in a VR helmet is "retina" and you won't see pixels no matter what.

It's just that's an enormous number of pixels, in a tiny surface area, and a colossal amount of data to move.
I'm sure the same was true for Digg, but those posts were all lost anyway. That's the danger of using a centralized, for-profit corporation's message forum service. By contrast, we can still look up posts from decades ago on USENET.
> At USD$3500, who is it for?

Everyone. It's a laptop replacement.

Realistically this "Pro" version is for early adopters. There will surely be a regular/SE/Lite version in a couple of years for the price of a MacBook Air.

> And who will develop software for something with such a small user base?

Everyone will, if they're smart. Being first to market on a new platform is huge, even if it will take a few years to have significant market penetration.

Angry Birds became a multi-billion dollar franchise for being one of the first iPhone games. Who knows what the equivalent will be for XR.

Once Computer Shopper became huge phone-book-sized things I quit buying them because I just didn't have the room or the time - fortunately our college library subscribed and I could peruse it there, but generally I'd read Byte, Creative Computing or Dr. Dobb's Journal instead. I recall when CS was kind of a newspaper prior to being a bound magazine format.
I don't even like wearing over-ear headphones because they make me feel too hot. Assuming the worst for a large headset is not a stretch at all.

The fact that the whistleblower is going public at a somewhat unknown network "NewsNation" either throws shade over the story or perhaps is a sign that no one believes the whistleblower.

Well that’s the problem then. You could say your problem has more to do with the relevancy of the results than the exact match operator (I personally don’t mind in this case since for the few times I’ve had to write python I’ve found the official docs not as useful as I’d expect).

As I said, I use that operator all the time and it works. I’d be the first to complain when it doesn’t. For instance, the - operator stopped working in YouTube a while ago, unfortunately.
