I’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’…

Solid state batteries. The tech is tantalizingly close, although not perfected yet. If and when they become available, these batteries will have a far higher energy density and degrade at a far lower rate than existing batteries.

I agree. Is there any chance this is what Tesla’s battery day could include?

So I learnt very recently that the PS5 has a cool approach where all memory is shared directly between the CPU and the GPU (if this is wrong someone please correct me). I would be really interesting to see how well the GPU in this could handle DL specific workloads, and if necessary, could it be tweaked to do so?

Because if so, that could be an absolute weapon or a DL workstation. If it does turn out to be feasible, I think it could be very easily justifiable to buy a few of those (for less than it would cost you to buy a major cloud provider GPU equipped instance for a couple of months) and have a pretty capable cluster. Machines get outdated or cloud provider cost comes down? Take them home and use them as actual gaming consoles. Win win.

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

Self-driving cars could work more like a hive mind. Humans can share ideas, but not reflexes and motor memory. So we practice individually, and we're great at recognizing moving stuff, but we never get very good at avoiding problems that rarely happen to us . And we know we shouldn't drive tired or angry or intoxicated but obviously it still happens.

Exactly. The way to improve performance on a lot of AI problems is to get past the human tendency to individualistic AI, where every AI implementation has to deal with reality all on its own.

As soon as you get experience-sharing - culture, as humans call it, but updateable in real time as fast as data networks allow - you can build an AI mesh that is aware of local driving conditions and learns all the specific local "map" features it experiences. And then generalises from those.

So instead of point-and-hope rule inference you get local learning of global invariants, modified by specific local exceptions which change in real time.

Sidewalk delivery robots. The problem is a lot easier that driverless cars (everything is slower and a remote human can take over in hard places) and huge potential to shake up the short-to-medium distance delivery business. It's the sort of tech that could quickly explode into 100s of cities worldwide like escooters did a couple of years ago. Starship Technologies is the best known company in the area and furthest a…

It seems like if they get popular they're going to run into problems with sidewalk availability. We're already using them for walking. You can add a few robots and not have any blowback, but once the novelty wears off, having to navigate around slowpoke robots on your walk is going to get old.

Svelte Flutter Zig, Nim & Crystal programming languages Please.build (bazel clone in Go) GraalVM's native image and CoreRT for .NET (though not much is heard about progress on CoreRT)

I've wanted to try mobile programming for a while (I am a web dev). Is Flutter a good choice for a mobile beginner like me, who hasn't done any mobile programming at all?

> UV light treatment of blood. What? No... No don't do this. This is a discarded idea from the era before molecular biology, and it was discarded for very good reason.

Opportunity can come from ideas that are correct but not generally accepted as correct. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4783265/ If it were to work it would be a useful new modality. I am not promoting it, but it's on my "watch list" due to efforts by AYTU at Cedars Sinai.

In my experience the commonest current mainstream use of this is for Sezary Syndrome / mycosis fungoides (cutaneous T-cell lymphoma). See for example:

This exactly. The PS5 and Xbox One X are commodity PC hardware, optimized for gaming, packaged with a curated App Store. Sony also won’t just sell you hundreds or thousands of them for some kind of groundbreakingly cheap cluster. They will say no, unless you’re GameStop or Walmart. Everyone with a high-mid-range PC already has more horsepower than a PS5 and it’s not doing anything particularly innovative or groundbre…

The fact that it can stream 5.5gb/s from disk to RAM says otherwise. Commodity hardware, even high end m.2 drives can’t match that.

* it’s my understanding that it directly shares RAM between the CPU and the GPU which means way less latency and more throughput.

This is how APUs (which is what the PS4/PS5/Xbox) use memory, the RAM is shared between the graphics and compute units. This can be an advantage since memory is quickly shared between the two (for example loading textures, etc).

This is also useful in computers since adding more RAM also adds more VRAM

I guess I'm much more conservative than other folks, but I think we've scratched only 10% of the surface of the benefits that things like Kubernetes, Consul, Vault and Terraform should/will provide. So they're on the list. I feel like at my job I'm pushing at the edges (as far as running large scale, stable production) and we've still got miles left. Also Bazel. I guess this is a boring answer.

Is there anything like "terraform provider for bare metal"? Would be soo convenient to just go from full nuke and pave to functional dev machine with a single config repo.
