함수형 프로그래밍 커리큘럼

함수형 프로그래밍에 중점을 둔 스칼라 책들은 훌륭한게 많지만 초심자부터 전문가까지 단계별로 가이드할 수 있는 커리큘럼을 추천하려고한다.

1. 초보자거나 스칼라 입문이라면:

• 데이브 거넬과 노엘 웰시의 크리에이티브 스칼라(무료). 스칼라를 배우려는 입문자들을 위한 책이고 재미있다.
• 노엘 웰시와 데이브 거널의 에센셜 스칼라(무료). 견고하고 성능좋고 스칼라다운 코드를 짜도록 도와준다. 다른 언어의 경험이 있는 개발자들을 대상

2. 더 심도있는 개념을 원하면:

• 폴 키우사노와 루나르 비아르드나손의 스칼라로 배우는 함수형 프로그래밍($36, 2.8만). 객체지향의 디자인패턴처럼 함수형 프로그래밍에서 자주 쓰이는 패턴인 데이터와 타입클래스들이 어떤 개념인지 직접 구현해보는 책. 스칼라 문법 정도는 익힌 개발자 대상.

Getting started with Linux kernel development

Prerequisites

The Linux kernel is written in C, so you should have at least a basic understanding of C before diving into kernel work. You don't need expert level C knowledge, since you can always pick some things up underway, but it certainly helps to know the language and to have written some userspace C programs already.

It will also help to be a Linux user. If you have never used Linux before, it's probably a good idea to download a distro and get comfortable with it before you start doing kernel work.

Lastly, knowing git is not actually required, but can really help you (since you can dig through changelogs and search for information you'll need). At a minimum you should probably be able to clone the git repository to a local directory.

Use apt to install the necessary packages:

sudo apt install -y slurm-wlm slurm-wlm-doc

Load file:///usr/share/doc/slurm-wlm/html/configurator.html in a browser (or file://wsl%24/Ubuntu/usr/share/doc/slurm-wlm/html/configurator.html on WSL2), and:

1. Set your machine's hostname in SlurmctldHost and NodeName.
2. Set CPUs as appropriate, and optionally Sockets, CoresPerSocket, and ThreadsPerCore. Use command lscpu to find what you have.
3. Set RealMemory to the number of megabytes you want to allocate to Slurm jobs,
4. Set StateSaveLocation to /var/spool/slurm-llnl.
5. Set ProctrackType to linuxproc because processes are less likely to escape Slurm control on a single machine config.

Install OpenCV 4.10 with CUDA 12.6 and CUDNN 8.9 in Ubuntu 24.04

First of all install update and upgrade your system:

    $ sudo apt update
    $ sudo apt upgrade

Then, install required libraries:

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

// Then open the channel you wish to delete all of the messages (could be a DM) and click the three dots on the far right.
// Click "Copy ID" and paste that instead of LAST_MESSAGE_ID.
// Copy / paste the below script into the JavaScript console.
// If you're in a DM you will receive a 403 error for every message the other user sent (you don't have permission to delete their messages).
