What if you're formatting your own SD cards for Raspberry Pi, and need control over the partition layout, filesystem, etc. Surely there are some best practices that this tool embodies, which one can follow to achieve the same level of

The latest Pi OS writes all logs to RAM, which might change your experience.

They decided to use the silicon space for other things. The Pi5 CPU is powerful enough to decode most h264 streams in software. The Pi5 has an h265 hardware decoder.

You need active cooling if you want to extract all the performance out of it. The standard cooling kits sold by Raspberry Pi are neat and cheap though, so not a problem in my experience. They have two options: A case with a fan on top, and

It's interesting that the standard "K" (number of elements with a shared scale) is 32. That seems to imply that the neural network will somehow learn to group weights at those 32-element boundaries. Does anybody understand ho

The short answer is: Yes, you must disable CPU frequency scaling in your BIOS if you're doing this kind of work (i.e. building cryptographic primitives that don't leak information via timing). See https://timing.attacks

TL;DR: The December 5th experiment was about proving to ourselves and our adversaries that we still understand how to build and validate nuclear weapons, despite the ban on testing.

It's conceivable that within a year or two, Copilot will be good enough to make the pain of the CMake language much more bearable.

This is an extremely accessible blog post, and very interesting, even if you're not deep into transformers.

Yes, this would definitely work, so long as the two cameras have sufficient overlap. If you were to use OpenCV's stitching code, then you could run the first few phases of that on your initial photo pair, which determine the camera ang

I'm convinced after the work I did on panoramas that one shouldn't need to involve user input. Maybe for very strange situations... but generally it shouldn't be necessary. This is especially true if you have access to the IM

I started from the OpenCV stitching_detailed example, and worked from there. That example runs pretty much out of the box on Android.

A panorama is built by stitching together many images taken from the same viewpoint. The 1st critical thing you need to know, is that the camera may not move. It may only rotate. If the camera moves a tiny bit, that's generally OK, but

Microsoft seems to have discontinued ICE a long time ago. As far as I know, the state of the art in panorama stitching is PTGui. I was working on mobile panorama stitching last year, and one of my datasets had a kitchen wall that was almost

Nice feature: You can adjust brightness of multiple monitors simultaneously. Every night I set brightness of both monitors to 15, and every morning I raise it back to 30. I've been hoping for a tool like this for years.

I love PEGs, but their error messages are usually vague, because it will backtrack out of a deep tree (where it should have discovered the actual error), and then presents an error much higher up ("computer says no"). Is there a m

I've tried to setup a 4K and a 2K monitor side-by-side, with one at 200% and the other at 100%.

How exactly do you make this work? Whenever I try and use different scaling on my different monitors, the OS (Ubuntu 20.04) ends up setting them both to the same setting.. or something else weird happens. I have tried a lot, and never man

I'm actually about to embark on exactly such a project. My plan is to use OpenCV's "stitching_detailed.cpp" example, and improve it from there. OpenCV's stitching is quite good out of the box, but I think I can impr

A toy illustrative example, summing two arrays: CUDA c[i] = a[i] + b[i] i += 1 Triton c[i:i+16] = a[i:i+16] + b[i:i+16] i += 16 The 16 in this example is the "block size", and could be anything. But this

This sits BELOW the automatic differentiation layer.

No, this is a DSL that allows people who normally write CUDA, to do so with less lines of code, and end up with a faster kernel. By embedding it inside Python you don't need to write your own lexer/parser.
