> Is the whole thing just so that the file is DRM-ed to hard that nothing else except expensive equipment can play it?

Could be the case. However, one of the quirks about Digital Cinema Packages (DCPs) is that they don’t use video codecs like H.264/AVC or H.265/HEVC. Instead, to maintain maximum quality, every single frame is individually compressed and stored with JPEG 2000, and they are played through like a slideshow, just at 24 frames per second. Needless to say this adds compute and especially storage concerns. Storing every frame of a movie individually quickly hits hundreds of gigabytes if not terabytes; and you need to decode and have every frame ready in less than 41 milliseconds, which is shockingly difficult even on high-end hardware. Even a modern Core i9 would have to be parallel and have multiple frames ready at a time because doing it a single frame at a time would be too slow (and thus, most projectors almost certainly use custom chips or FPGA-based decoders but that's really, really expensive). Do I need to mention read speeds and network traffic? If every frame is, say, just 5MB, that is over 960 Megabits per second, saturating a Gigabit link.

Another thing to consider is the multitude of speakers. Dolby Atmos is object-based, meaning there aren’t specific audio streams for specific speakers like in the past. Every speaker’s location is individually stored in the playback device varying between theaters, and the sound is calculated and mixed for that specific theater’s audio setup at the time the movie is played. When you are calculating audio in real-time for 30 or more speakers, the compute costs add up, potentially into custom hardware / FPGA territory. Also that "saturating a Gigabit connection" doesn't include the amount of data that the audio uses, and considering it's 24-bit PCM without any compression for dozens of streams for the objects, that's also pretty substantial. Just 2 streams of 16-bit PCM for ~70 minutes on a CD takes about 700MB.

So, just for one movie, with every frame taking 5MB (possibly more or less, we don't know how big they actually are) and audio taking whatever it takes, you would need a 2.5Gig Ethernet link to be safe, and storage that can deliver that (which is also why an external hard drive is out of the question for actual playback, only very recently do we have built-in NVMe SSDs that can deliver that kind of speed, but we still don't have any external SSDs that can deliver anywhere close; it just has to be RAID on multiple storage devices). Now consider what you need for a theater with 12-20 screens at a time. The storage amount and speed requirements is substantial. Now consider this has been standard for over a decade and think about how expensive this would've been to implement in, say, 2013. Oh, and that storage had better not fail, ever, or your entire theater is down, and there's a lot of refund requests and unsold tickets until it's running again.
> This just isn't true. I had regular power outages when I lived in the US

And I have never had an outage in the 20+ years I've lived in SF (except for the one time they were doing maintenance and had announced the outage days in advance).

See? Anecdotes prove nothing. Remember: I wrote "rarely". I would say 99.9999% availability (for me) is pretty good.
Better products and competition is good for the consumer.
For me as well. And when my stochastic probability professor posed this question to the class by way of hands, it was nearly unanimous in favor of the 0/100% end behavior.
Yes, Wikipedia is under a license allowing others to publish the content, and others have over the years.

> if you're really worried about it, you as a parent should be the one to do something about it, not the government, because you'll reach a point in time where they are the ones saying how you should and shouldn't raise your kids

I suspect part of the reason policies like these have popular support is the twisted idea that I should be able to dictate how you raise your kids...
Actually I think the financial system doesn't function as a rigid categorization structure. I think it's more like a negotiation of resource management. Things like leverage and political power apply here in ways that cause the rules to become far more flexible. A powerful government like the United States commands far more favorable (good faith) experiences with finance than, say, a person who is late on paying rent due to the same checking error.
I'm not an Apple follower, what innovation have they produced in the last 5+ years that the sibling comments deride Google for? I would argue the TPU is far more interesting than the M1, other than that, is it not just marginal improvements on existing products?
The post-pandemic economic environment is toxic.

Everyone seems to have come out of the pandemic convinced that they need to tighten whatever screws they have to get theirs. And that triggers other people to do the same thing. Cheating enters the realm of possibility because people (correctly and incorrectly) believe others are doing the same thing.

It's gross and feeds on itself. I'm not sure what will help it get better.
However when recording a good amount of data is being shuffled through ram, the cpu has to encode the wavestream, if stored the flash memory will have to do it's thing, if transmitted, the radios will have to wake up and run through all the data as well. The microphone does not exist in isolation.

I'm curious what the legal ramifications of adding "this code is not to be used for any ML algorithms, failure to adhere to this will result in a fine of at least one million dollars" (in smarter writing) to a software license would be. Seems like a dumb idea/not enforcable but maybe someone with software licensing knowledge can chime in.

I read these comments not as a defense of cheating, but as resignation that "This is just how the world is." Your view is right at home in a Star Trek The Next Generation world where everyone's needs are met and people act ethically, with good intentions and are in return treated fairly. A civilized, meritocratic world that doesn't exist. Like it or not, we live in a zero-sum dog-eat-dog world that pits neighbors against each other for the scraps left over after an elite few take 95% of the world's value. For every fraction of a percent you can grab, that's a fraction of a percent that some ethical moron can't grab. If you try to follow the Star Trek rules in this world, you're not going to get very far.

Look at this "personality type" as you call it: People who bullshit their way through life, self-promote, swindle, grift, fake it til they make it, hustle, exploit people's good intentions, take credit for the work of others, and so on... They aren't weirdo sociopaths who simply go get an MBA. They're CEOs, SVPs, business and political leaders, the ultrarich. They're Presidents and Senators. They are the elite, the few who our society is set up to most highly reward. Of course people who want to get ahead are going to emulate this behavior. It's practical. It works in the world that we have set up.

I'd love to live in the Star Trek world. I'm one of those naive suckers who thinks hard work in the trenches should be rewarded. At work I often sit there doing the dirty gritty work that needs to get done, while peers write bullshit presentations and get face-time with the execs, and schmooze their way to promotion after promotion, and it sucks. If I was younger and had a lot more ahead of me, I'd probably cheat and grift like the rest of em, and if I could send a message back decades to 20-year-old me it would probably be "lose the ethical spine and take whatever you can."

We don't take bit flips seriously enough, practically every consumer device uses non ECC memory, very few folks use filesystems (e.g. ZFS) that can detect corrupt blocks. Even when using those things together it's still not perfect.

I like hearing about your pre-"upgrade" local theater. We had one like that around here even eight years ago that did second-run screenings in addition to loads of foreign films or rescreenings of films from decades ago. Great experience, super cheap. Unfortunately there was basically a hostile takeover of it by a guy who bought into the big seat vision.
All of the examples cited use a repudiation of the backing of currency or bonds with gold or silver. I don't think I'd call that a default. I know that there is a political minority that still thinks that breaking away from the gold standard was a mistake, but that's not the same thing as straight up refusing to pay back holders of government debt.

That's not "twisted idea," unless you think it's OK for parents to beat their kids.

Have you ever troubleshot an outage with a whole team? I am strongly in the belief that any more than two people working on an outage makes it last longer.
The hire-slow, fire-fast paradigm might be an employers dream, but it is _terrible_ for employees. In the worst-case situation you end up quitting your job and maybe even moving to be let go with little warning? That's rough. I think if the employer wants to fire someone, they _should_ be paying for severance.
Tinkerbell: Provision and manage bare metal, anywhere
What happens if the code gets pre-empted between free_foo(whatever) and the if-statement, memory allocation gets changed, and subsequently dereferencing the pointer to read whatever->did_something causes a page fault?

I am making assumptions here: That pre-emption is possible (at least some interrupts are enabled), that "whatever" points to virtual memory (some architectures have non-mappable physical memory pointers), and that a page fault at this point is actually harmful.

However I do want to point out that the reasoning why your example is not exploitable isn't as easy as it first seems.
Hi! I just stumbled upon this and was very surprised by his comments on the amount of waste heat - 100% waste of energy for residential and commercial use, 70% for industry and 75% for transport.

I'm not a climate scientist and would love for someone to comment on his comments on greenhouse gas - I don't know what I think of that, he's pretty scathing.

And please notice there was a correction and an update to the paper.

Edit: Waste heat is two orders of magnitude less energy than the energy retained by Greenhouse gases - while it is a cause of warming, it's less than 1%!

I'm still of the opinion that just swapping current phone assistants with LLMs is naive and bad. For one thing, they need to make sure they don't break current functionality, like for setting timers and reminders, and and doing math calculations (which LLMs are not good at unless you get it to pass the query off to a dedicated calculator like Wolfram Alpha), etc. But more importantly, when you use something like ChatGPT through the web interface there's a bunch of warning labels all over to remind you "this thing will make up information."

For something with such an easily-accessible interface that's baked-in at an OS level, I think a fail state of "sorry, I don't know how to help with that" is better than stating a bunch of false information as fact.
Ya very odd claim by OP. Looking at the history, while not great, it certainly isn't every day nor has any type of pattern.
I feel the same way, after 1.5 yrs in Mexico.

Too much:

- Noise

- Lawless culture & government corruption

- Pollution & its related "who cares" culture around trash & toxic chemicals

To little:

- Infrastructure

- Education

- Respect for nature & concern for reducing the impact of pollution

- Enforcement of health & environmental regulation

That said, there are ardent environmentalists & industrious, educated people. They're just at a low concentration due to the human development itself-- it takes time for societies to develop to high levels of living standards and human achievement.
You'd be surprised how prevelant the direct intervention of state is in all aspects of life, even in the "democratic" EU - nobody sees this dictation a problem, but it's especially more acute being Western - especially when looking at central, eastern and Baltic states.
Have you ever looked at a successful founder and thought, “Wow, they must have just gotten lucky”? It’s easy to assume that someone had overnight success, but the truth is often much different. It’s also easy to use this as an excuse why you won’t build your own project.

In fact, most builders and makers have many failed projects before they finally hit on the one that takes off. These failures are often the result of years of hard work and determination, and they are just as important as the success that eventually follows. This post is inspired by Pieter Levels’ tweet on how only 4 out of hit 70+ projects ever made money, and 95% of everything he made failed.

> You're storing all of a user's post history on their own device in the case of an immediate outage. That's equivalent to Gmail storing all of your emails on your device in case you want to immediately pack up and move to another email provider.

In the world I currently live in, all my emails are stored locally on my devices. Also, text files take up little to no storage, so why does it matter?

I've only ever had to hire one person to work beneath me, but that sounds like how I ran the interview.

We were hiring students for a temp position. We're a Controls Engineering company, but my department is dealing with more traditional languages for supporting applications and needed extra help for a bigger project. I know the tech we use isn't standard in the university so the interview was asking students about how they approached their major projects and their methodology for learning new tools/languages.

The first guy who straight up said "I already know enough of C++ and Java, I suppose I'd just google how to do x in c# and branch from there" got the job. Because...yeah, that's about it.

These two part course rearranged my brain about what really programming is about. It is about working with data and the way the data is arranged determines how most of the program/functionality (pun intended) is written.

Programming is not a series of instructions to be executed by the computer. That was when assembly language programming was the main stay of programming computers. Not now.

Hello, author here. Happy to answer any questions about the post if you have them.
The biggest influence on Marquez, according to Marquez himself, was Juan Rulfo's Pedro Páramo (1955), which is a masterpiece. Borges considered it one of his favourite books, but it's still almost forgotten in the English-speaking world. Highly recommended to anyone who likes magical realism.
