Imagine this: it's Sunday afternoon at 1pm, and you want to watch some live content. But you don't have a TV subscription. So you do a little Googling, and eventually you find yourself on a sketchy website where you can watch the content you're looking for. But while the website has a video player, it's surrounded by advertisements, and probably a cryptominer too. You don't want this website eating your CPU for 2 hours while you're watching your favorite Sunday afternoon content.

Wouldn't it be nice if you could watch that video in VLC instead? Then you can close the sketchy website and still watch your content. It's like having your cake and taking a bite of it too!

Here's how you do it:

1. Capture the m3u8 request in dev tools. Open the site (or just the iframe, if possible) in DevTools and click "play." Search the network tab for m3u8 and grab the first request.

2. Run VLC with command line flags to set the User Agent and Referrer. From the request body, you need to copy the requested URL,

I often find myself getting frustrated with code—be it code written by me or by others. This, I find, is because that particular code disregards readability.

This frustration of mine often bubbles up in the form of colorfully disparaging commit messages. I decided that it would be more productive to instead type-down what I feel are some decent coding practices.

I've added examples where applicable and tried to explain the why behind the practices.

This document is prone to recency bias. The practices here come to mind because

Crippling Facebook

Facebook works with advertisers to target you. These instructions are one of the many ways to begin crippling that relationship. When AI targeting is crippled, your psychosecurity improves :)

2. Maximize the browser window
3. Press F12 and click on the Console tab
4. Select the code below, copy it, paste it upon the Console line (The area next to the > character in the Console window), and press enter:

This worked on 14/May/23. The instructions will probably require updating in the future.

llama is a text prediction model similar to GPT-2, and the version of GPT-3 that has not been fine tuned yet. It is also possible to run fine tuned versions (like alpaca or vicuna with this. I think. Those versions are more focused on answering questions)

Note: I have been told that this does not support multiple GPUs. It can only use a single GPU.

It is possible to run LLama 13B with a 6GB graphics card now! (e.g. a RTX 2060). Thanks to the amazing work involved in llama.cpp. The latest change is CUDA/cuBLAS which allows you pick an arbitrary number of the transformer layers to be run on the GPU. This is perfect for low VRAM.

• Clone llama.cpp from git, I am on commit 08737ef720f0510c7ec2aa84d7f70c691073c35d.

Because cross-compiling binaries for Windows is easier than building natively

I want Microsoft to do better, want Windows to be a decent development platform-and yet, I constantly see Microsoft playing the open source game: advertising how open-source and developer friendly they are - only to crush developers under the heel of the corporate behemoth's boot.

The people who work at Microsoft are amazing, kind, talented individuals. This is aimed at the company's leadership, who I feel has on many occassions crushed myself and other developers under. It's a plea for help.

The source of truth for the 'open source' C#, C++, Rust, and other Windows SDKs is proprietary

You probably haven't heard of it before, but if you've ever used win32 API bindings in C#, C++, Rust, or other languages, odds are they were generated from a repository called microsoft/win32metadata.

In the olden days, HTML was prepared by the server, and JavaScript was little more than a garnish, considered by some to have a soapy taste.

After a fashion, it was decided that sometimes our HTML is best rendered by JavaScript, running in a user's browser. While some would decry this new-found intimacy, the age of interactivity had begun.

But all was not right in the world. Somewhere along the way, we had slipped. Our pages went uncrawled by Bing, time to first meaningful paint grew faster than npm, and it became clear: something must be done.

And so it was decided that the applications first forged for the browser would also run on the server. We would render our HTML using the same logic on the server and the browser, and reap the advantages of both worlds. In a confusing series of events a name for this approach was agreed upon: Server-side rendering. What could go wrong?

In dark rooms, in hushed tones, we speak of colours.
