Nvidia has more money than God. Worst case they'll buy the competition.

The question is whether robotics will look like a some number of platforms with little development to adapt to different scenarios, or a million types of machines that are highly fit for purpose.

Because the first situation won't create that many jobs. The second one might.

Is there a possibility to create a wireless point-to-point link ?

This is interesting, for sure.

Thinking about this, I think what happens if we take it to the extreme - a system that lets a single user enter his route to work - and compare how various transportation systems, including innovative ones, would impact his day to day.

It's really hard to build such tool, and if it's done well and made appealing to users, it could be the base of a political tool for people to pressure their representatives to implement new and better systems and improve voters lives.

About integrated memory: Gemini says that between 85%-90% of PCs and laptops never upgrade their memory.

On the other hand, multi-die integration can greatly increase memory bandwidth.

So it's a reasonable move to integrate memory.

It's probably possible to develop analog adsl chips in 1990 semi tech. But pretty difficult.

As someone that is sensitive to displays, one of the best features of XFCE, unlike others desktops, is that it doesn't cause eye strain, probably because it doesn't play tricks - a pixel at a certain color is stable, and not dithered(if you choose) and higher level primitives are also stable and don't play time/frequency based games.

I hope XFCE preserves this, it is a killer feature in today's world.

On that same note,of reducing the barriers for Linux usage.

Would it be possible to create a Zorin OS USB drive that after inserting it into the USB drive of a laptop:

The user would get a running Linux, with the UX they know(win 10/11), with full speed and full capabilities - without installation ?

New comment by petra in "Qualcomm to acquire Arduino"

petra — Tue, 07 Oct 2025 16:44:23 +0000

I agree. The Arduino brand isn't for professionals.

But let's say tomorrow they come together with bundle/partnerships to create a new, great dev environment, very easy, that a mechanical engineer can prototype a great robot for a niche use case,and continue to use that chip and code, with some changes in V1 production ?

Is there value to the Arduino brand and community than ?

Zorin OS is very similar to windows, regular users just use it, without learning anything new.

But still, marketing this must be brutal.

//And the ability to speak English natively is already in high demand throughout most the world, meaning if you ever get tired of online work and want some people time, you can have a job in like 5 minutes, particularly if you look decent and have a college degree.

What typed of jobs is this referring to, besides teaching English ?

A proper solution ?

I have ideas, but their value is mostly in making me sound smart.

In reality I don't have realistic, implementable ideas on how to get out of this mess. Just wishes.

There's a potential for 100x+ lower cost of chips/energy for inference with compute-in-memory technology.

So they'll probably find a reasonable cost/value ratio.

Interesting link, thank you!.

One other possible immune system link is the relationahip between the parasite toximoplasis gondii to schizophrenia.

If I'm not mistaken that's the paper about that:

//If an application takes off, it is eventually cheaper and more performant to switch to ASICs,

That's part of the FPGA business model - they have an automated way to take an FPGA design and turn it into a validated semi-custom ASIC, at low NRE, at silicon nodes(10nm?) you wouldn't have access to otherwise.

And all of that at a much lower risk. This is a strong rational but also emotional appeal. And people are highly influenced by that.

Z-Library has a keyword search. Personally i didn't find it too useful, especially given Google Books exists. It's not easy to create a quality book search engine.
