#362I wasn't impressed with the engineering and JS client-side bundles on Integromat.

#363Self-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,…
I never really paid attention to consoles (not a gamer in any way) but the ps5 sounds impressive. Shame Sony have a very Apple-like approach to their products and lock everything up. If they bundled up that hardware with linux support, sales would go through the roof and into orbit. I'd personally get a bunch of these and build myself a cluster.

> 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…
Ps3 was used as Debian clusters in my university and would be in larger scale if not for a) huge cost in my country at start b) medium availability c) "other systems" fiasco.
There was significant interest in grid scholar community.

#3651. 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 permissions on their KB articles system. I like intercom's articles but (at the time) wanted to restrict them to actual customers. So I put a CF worker in front that gates based on a cookie set by my app.
These are both trivial, stateless 5-line scripts. I like that I can use CF workers to fundamentally change the behavior of hosted services I rely on. It's almost like being able to edit their code.
Of course, this only works for hosted services that work with custom domains.

#366Earlier quoted context omitted.
string_view, span and ranges are not conductive to safety, quite the opposite.
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 standard terminology to refer to this as a borrow, which helps. Attempting to retrofit Rust concepts to C++ is helping, but often they're cosmetic, because they say the right thing, but aren't checked. However, saying the right thing makes it possible to do more and more static checking.

#367I’m a little surprised that there aren’t any mentions of Obsidian, while there are at least two mentions of Roam. To all Roam lovers, and to all intellectuals in general, I’d recommend you to check out Obsidian [1] from the makers of Dynalist. It’s also a tool made mainly for Zettelkasten, but it is offline and local by default. It’s not an outliner like Roam, but rather a free-form text editor. I feel that Obsidian’…

Just remember that not everyone is in your little concern-bubble, and one or two explanatory sentences would be very welcome.

Maybe they sell the H/W at a loss (especially considering R&D + Marketing spend) - and the real strategy is to turn a profit on PSPlus, licensing and taking a cut out of game distribution. If that's the case... you or me building a linux cluster will actually hurt them =)

But surely it's a step towards more safety. Compare to passing char * around or ref/ptr to string.
Sure C++ doesnt have a borrow checker but these types encourage the idea of "reifying" lack of ownership rather than keeping it ad hoc
