Your container does not have GPU drivers installed
So, how does PyTorch inside it actually use the host's GPU?

Let me explain 🧵

If you're building AI agents, read this twice:

There’s a new invisible OS being written for the autonomous future. It’s built on two emerging protocols:

• Model Context Protocol (MCP)
• Agent-to-Agent Protocol (A2A)

Here’s why they’re a big deal—and why you need to care:

The zero-to-project speed of @dhh is impressive.

I'm grateful to see my simple shell script, resonating with others in the developer community! Reaching 16 stars on GitHub is a small milestone, but it motivates me to continue learning and creating useful projects.

Think Assembly code is useless to learn?

Age of Empires I+II used ~13,000 lines of x86 32-bit assembly code.

"The use of assembly in the drawing core resulting in a ~10x sprite drawing speed improvement over the C++ reference implementations, and AoE's drawing core was notably faster than competitors like StarCraft"

- Matt Pritchard, Lead Developer of AoE I+II

Compilers of that area did not take advantage of things like the cache architecture and UV pipes of the first Pentium processors, so they had to be hand written in assembly.

Another speedup came via hand-managing register usage carefully, to avoid "register starvation", which was even a problem with C++

Holy shit @elnardu actually got “use c” working 😳

One month since switching from Lambda to EC2. Cost savings are hundreds of thousands of dollars on annual basis.

We haven't used reserved instances yet, and I'm convinced that by moving a few more endpoints from PHP to Go, we could reduce the number of instances to half.

I recently released version 1.4.0 of the Pritunl Client GitHub Action.
