If you use a Mac and want to upgrade the firmware of your Feker IK65 keyboard to get VIA support, this guide is for you. I will just list the high level steps to take. I will assume that the keyboard is connected over USB.

Where to get the firmware

At the time of writing, you get it from [Epomaker's website][1]. If this link doesn't work, search for "feker" on their website. I noticed that the link to the firmware calls it an lk65 (lowercase L vs uppercase I), which explains why I found it so difficult to find this software on search engines.

How to run StarCoderBase 1B SFT on a MacBook Pro with Apple Silicon

These are notes on how I managed to get StarCoderBase-1B-SFT model compiled into a quantized version such that it can run locally on my MBP M1 Pro and be queryable through an OpenAI API-compatible server. [StarCoderBase][1] is a model trained/tuned for programming tasks. The [1B parameters SFT model][2] I am using in this article is a version of the model that has had supervised fine tuning applied to it. I am just going to call this "StarCoder" in the rest of this article for the sake of simplicity. Number of parameters that a model has is going to impact resource usage, so a smaller version of the model makes it more

Delete multiple Git branches with a UI

This assumes you have installed [fzf][1].

$ git branch --no-color | fzf -m | xargs -I {} git branch -D '{}'

Press tab to mark a branch, shift-tab to unmark. Press enter and all marked branches will be deleted.

Genshin Impact: Albedo vs Mona crafting talent, who is better?

In Genshin Impact, you can craft materials of a given rank from three materials of the rank just below, eg. you can craft one gold book from three blue books.

Albedo has a talent where crafting a weapon ascension material has a 10% chance of giving double the output. Mona has a talent where crafting a weapon ascension material has a 25% chance of refunding a portion of the input materials.

Setting session variables in an RSpec Rails request spec

You are writing a spec with type: :request, i.e. an integration spec instead of a controller spec. Integration specs are wrappers around Rails' ActionDispatch::IntegrationTest class. I usually write controller tests using this instead of type: :controller, mainly because it exercises more of the request and response handling stack. So instead of writing something like get :index to start the request, you would write get books_path or similar.

One of the issues with using type: :request is that you lose the ability to

Installing mysql2 gem

This is always an annoying process, especially when you are setting up a new computer. I assume you are using macOS + homebrew. I also assume that you want to run an older version of MySQL (although the instructions should be adaptable).
