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,…

Nice post. I think the PS5 read might be a little off though. The pro edition is likely to be 600ish USD and come in a little lower than 14 of the tflops.

I think you've vastly understating current hardware prices. An 8 core 2nd generation Zen chip appears to retail for $290. The PS5 reportedly has a custom GPU design, but for comparison a Radeon 5000 series card with equivalent CU count (36) currently retails for $270 minimum. Also, that GPU only has 6GB GDDR6 (other variants have 8GB) but the PS5 is supposed to have 16GB. And we still haven't gotten to the SSD, PSU,…

Ryzen 2nd-gen 2700 is out of stock currently, but it used to go for as low as $135-150, it's absolutely not a $290 CPU (perhaps you're looking at 3rd gen ryzen? 3700x?). I haven't looked at what a GPU equivalent would be, but by the time PS5 hits the market, I doubt going to be anywhere near 270$. As long as there aren't any supply chain disruptions (as there are now). It appears that the real killer is the hardware-…

Zen2 = Ryzen 3rd, not 2nd.

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 b…

I recently bought an Ivy Bridge CPU low power CPU + motherboard for $35 and 8 GiB of ram for $25. No need to buy new hardware if you can do away with old.

Thanks for ZeroTier! Managed to convert a few friends from using Hamachi for LAN games, which was always a pain to setup previously. It simply just works for my needs.

ooh! so it could replace Hamachi. I think this is one use case (without using the product name) that can be listed in a uses-cases page. Hope other Zerotier users would chime in with more use cases.

ZeroTier emulates a L2 Ethernet switch over any network, so anything you can do with Ethernet basically.

You make networks, add stuff to them, and any protocol you want just works: games, ssh, sftp, http, drive mounts (though they can be slow over the Internet), video chat, VoIP, even stuff like BGP or old protocols like IPX work.

1. https://www.starlink.com/ Finally, truly global and low latency satellite internet. 2. Generative models for video games - https://aidungeon.io/ is barely scratching the surface. Story, art, animation, music, gameplay, it will all be generated by models in the future. 3.

Would love to read up on the advancements in NLP. Can you share some links?

Especially if it allows more people to write systems programs. WASM - Mostly as a compile target for Rust, but I think this changes the way software might be deployed.

Just checked out the website, how is it any different from Dynalist or Workflowy?

I'm obviously talking about matching human performance and this is the hard problem

There is also an easy solution of just staying put. I have driven in snow a few times that I was not sure I was even on the road. Or the only way I knew I was going the right direction was because I could vaguely see the break lights of the car going 15mph in front of me through snow. That is an easy problem to solve though because I simply should not have been driving in that.

> Seconded that dipping a toe in to Rust has changed how I think about C++ and object ownership. Loose pointers and copy constructors now make me feel un-clean! Move ftw. It's funny, because while it's certainly become more influential lately, that subculture existed as a niche in the C++ world before Rust and before C++11. So much so that when I first heard about Rust I thought "these are C++ people."

The original (and long dead) Rust irc channel used to be full of C++ people chatting with OCaml people. Those were the days :)

That entirely matches my idea of how Rust came to be, some sort of pragmatic co-development across two different philosophical camps. In many ways, Rust is a spiritual successor to both languages, if only it was easier to integrate with C++.

Different use cases. Go was designed to be easy to use for un-demanding problems. People mostly switch to Go from Ruby, Python, or Java; or from C in places where C was an unfortunate choice to begin with. Rust is gunning for C++ territory, in places where the greater expressiveness of C++ is not needed or, in cases, not welcome. They would like to displace C (and the world would be a better place if that happened) b…

So you’re saying it should have better performance than go?

I am mainly saying it is suitable for solving harder problems than Go. Most problems are not hard; Go is good enough for them, and easier to learn and use well.

All these languages are Turing-complete. The difference is in how much work it is to design and write the program, and in whether it can satisfy performance needs.

C++ wins here by being more expressive, making it better able to implement libraries that can be used in all cases. Rust is less capable, but stronger than other mainstream languages.

An example I can give: I use WebAssembly for a few cross-platform plugins. E.g. An AR 3D rendering engine in C++ and OpenGL. With very little effort it is working in browser. No bespoke code, same business logic, etc. Saved a lot of time vs creating a new renderer for our web app. For me it allows a suite of curated plugins which work cross-platform. The web experience is nearly just as nice as the native mobile and…

I build a slower version of something with the same idea 13-14 years ago in Flash for http://www.makeoversolutions.com which most of these makeup companies licensed back then. I moved on from that a decade ago but it was a neat project at the time. But I deployed my first integration of WASM about a month ago for PaperlessPost.com. It is a custom h264 video decoder that renders into a canvas that manages timing relat…

I feel like I am looking in a mirror!

Ten years ago I did the same but in Java and JOGL (before Apple banned OpenGL graphics within Java Applets embedded within a webpage). Was used for AR Watch try on within https://www.watchwarehouse.com and Ebay. The pain of Flash and Applets still wake me up at night.

I'm also building something very similar but with the ability for custom codecs (https://www.v-nova.com/ is very good). Probably the same issues too! Could I know more about your solution?
