Weekly Coding • 2026-01-18
It's time for my weekly diary.
-= LeetCode =-
This week I solved 13 problems:
- 188. Best Time to Buy and Sell Stock IV 📘 TypeScript
- 189. Rotate Array 📘 TypeScript
- 190. Reverse Bits 📘 TypeScript
- 191. Number of 1 Bits 📘 TypeScript
- 192. Word Frequency 🐧 BASH
- 193. Valid Phone Numbers 🐧 BASH
- 194. Transpose File 🐧 BASH
- 195. Tenth Line 🐧 BASH
- 196. Delete Duplicate Emails 🔰 SQL
- 197. Rising Temperature 🔰 SQL
- 198. House Robber 📘 TypeScript
- 199. Binary Tree Right Side View 📘 TypeScript
- 200. Number of Islands 📘 TypeScript
It turns out, LeetCode has little tasks that need to be done in programming languages like BASH 🧐 This was a surprise for me.
-= AI =-
I keep generating different things for myself but I'm not sharing them. Some time ago, I learned about quantization for AI models. It appears that using the original model version is not always necessary. If you look online, you can find various versions compiled with a specific number of bits:
- fp16, fp8
- Q8, Q6, Q4, Q3, Q2
The number indicates the number of bits, and many models can be used in version Q4 with almost no quality loss, while this version is half the size of fp8 and four times smaller than fp16 😏 The only inconvenience is that you need to search for these versions on file dump sites like Huggingface and CivitAI; and hope that some kind user has collected and uploaded the desired build in a preferred format. From my experience, it's always better to get a powerful Q4 model than a weak one in Q8 or fp16. However, at levels Q3 and below, artifacts and hallucinations start to appear 🥵
