> The Playstation 5. 8 CPUs at 3.2GHz each, 24GB of RAM, 14 teraflops of GPU, and a big solid state disk. That's a lot of compute engine for $400. Somebody will probably make supercomputers out of rooms full of those. Mmm, this sounds like exactly what people said at the time the PS3 was going to be released, and I can only recall of one example where the PS3 was ever used in a cluster and that probably was not that…

Most of that power came from the Cell processor, which was awesome but supposedly hard to develop for. I assume they’ve learned that lesson.

If by “learned” you mean changed focus from making it (uniquely) awesome and instead making it easier to develop for: yes.

And if by “learned”, you also mean “were convinced by Mark Cerny“ (who is still leading design of the PS5), then also yes.

Rust. It's an extremely interesting language for me, I'm trying to learn bits of it every few years and while I still don't have any real tasks, I just love its development. May be it'll be the last and only programming language that everyone will use for the foreseeable future.

1. Cloudflare Workers, I don't have the bandwidth to experiment with it right now but it interests me greatly. https://workers.cloudflare.com/ 2. Rust - definitely will be the next language I learn. Sadly the coronavirus cancelled a series of meetings in Michigan promising to give a gentle introduction to Rust. https://www.rust-lang.org/learn

I've done a couple neat (IMO) things with CF workers. - I use imgix to manipulate images in my app, but some of my users don't want anyone to be able to discover (and steal) the source images. Imgix can't do this natively; all image manipulation instructions are in the URL. So I put a CF worker in front of imgix; my app encrypts the url, the worker decrypts it and proxies. - A year ago, intercom.io didn't support per…

It’s pretty incredible. You can put it over any site and build your own A/B testing or targeting based on the user or the link used to get to your site.

can you explain why you think that?

Things like "It is the programmer's responsibility to ensure that std::string_view does not outlive the pointed-to character array." "string_view" is a borrow of a slice of a string. Since C++ doesn't have a borrow checker, it's possible to have a dangling string_view if the string_view outlives the underlying string. This is a memory safety error. Rust has educated people to recognize this situation. Now it's standa…

Rust hasn’t "educated people" about "borrowing".

Lifetime management has always been there for any developer dealing with resources in any language. Over the years, languages and specialized extensions and tools have offered different solutions to help with that problem.

What Rust has brought is a system that checks explicit tracking embedded into a mainstream language.

Self-driving cars. Now that the hype is over and the fake-it-til-you-make-it crowd has tanked, there's progress. Slowly, the LIDARs get cheaper, the radars get more resolution, and the software improves. UE5's rendering approach. They finally figured out how to use the GPU to do level of detail. Games can now climb out of the Uncanny Valley. The Playstation 5. 8 CPUs at 3.2GHz each, 24GB of RAM, 14 teraflops of GPU,…

> C++ getting serious about safety. Buffer overflows and bad pointers should have been eliminated decades ago. We've known how for a long time.

The crowd that use C++ needs raw pointers sometimes, and you can't really prevent bad pointers and buffer overflows when they are used. There is a reason why Rust, which goal is to be a safer C/C++, supports unsafe code.

Smart pointers is a very good thing to have in the C++ toolbox, but they are not for every programmer. Game programmers, if I am not mistaken, tend to avoid them, as well as other features that make things happen between the lines, like RAII and exceptions.

The good thing about that messiness that is modern C++ is that everything is here, but you can pick what you want. If you write C++ code that looks like C, it will run like C, but if you don't want to see a single pointer, you have that option too.

Sony is selling them with little to no profit as they expect to earn on games. Guess why their capabale and cheap hardware is locked down to avoid using it for anything except playing bought games ;) Anyway you can jailbreak ps4 to 5.0.5 firmware and there are unpublished exploits in existence that are waiting for ps5 to be released.

Looks like I found that "home server" to replace my over-use of cloud resources that I've been looking for!

Well, let me recomend something else, check asrock mini-itx motherboards with on-board cpu. You can get those for ~150 euros, throw in some ram (~60 euros) and some disk (100euro) + some chasis (Phenom mini-itx for instance, ~100euros). For home server this will work great :)

I am running home server (100% self hosted including emails) with J1900-itx motherboard with 20Tb of disk space (zraid) for years. No need to bother with ps4/5.

Humans don’t need LiDAR to recognize billboards

Self driving cars can't rapidly move their cameras in multiple spatial directions like humans do on a continuous basis. Also we have a pattern and object detection computer behind our eyes that nothing on this planet even remotely comes close to.

Humans have about 2° field of sharp vision. Computers with wide angle lenses don't have to oscillate like the eyes do.

Libresilicon [1]. Extremely important to our freedoms from corporate and state tyranny to make chip manufacturing libre. > We develop a free (as in freedom, not as in free of charge) and open source semiconductor manufacturing process standard, including a full mixed signal PDK, and provide a quick, easy and inexpensive way for manufacturing. No NDAs will be required anywhere to get started, making it possible to bui…

This is really really exciting. Thanks

It is. They are down to 1 um, so they need to make a bit more than an order of magnitude improvement to become performance competitive - 100 nm is early 2000s technology, Raspberry Pi is 40 nm size.

Humans are underrated.

You are right, for example, humans don't need anywhere near the amount of training data that AIs need.

It seems to me that humans require and get orders of magnitude more training data than any existing machine learning system. High "frame rate", high resolution, wide angle, stereo, HDR input with key details focused on in the moment by a mobile and curious agent, automatically processed by neural networks developed by millions of years of evolution, every waking second for years on end, with everything important labelled and explained by already-trained systems. No collection of images can come close.

Web Assembly It's interesting in a bunch of ways, and I think it might end up having a wider impact than anyone has really realized yet. It's an ISA that looks set to be adopted in a pretty wide range of applications, web browsers, sandboxed and cross platform applications, embedded (into other programs) scripting, cryptocurrencies, and so on. It looks like it's going to enable a wider variety of languages on the web…

I want to believe... I always thought WebAssembly had a lot of potential, however, in practice it doesn't seem to have turned out that way. I remember the first Unity demos appearing on these orange pages at least 4 or 5 years ago, and promptly blowing me away. But, after an eternity in JavaScript years, I still dont know what the killer app is, technically or business wise. (Side note - I encourage people to prove m…
