Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:

RTFM.
Dựng và chạy hệ thống với các settings được recommend trong doc. Ví dụ Redis sẽ có sentinel hoặc Redis cluster hoặc standalone.
Explore tất cả các feature của system hoặc tất cả interface của library, nhất là những feature nào có vẻ fancy.
Build from source. Chạy lại bằng build object được sinh ra. Ngó thử xem hệ thống có bao nhiêu components, dependencies.
Đọc thử design doc nếu có
Debug thử xem giữa các component liên hệ với nhau như thế nào. Thông thường các hệ thống đều có doc.
Pick một flow đơn giản nhất, Tìm thử entrypoint trong code. Đặt debugger xem thử chạy ra sao.
Change thử một feature nho nhỏ xem thê nào

Lenovo ThinkPad W541

The W541 is a workstation laptop based on the Intel Haswell architecture which has an Nvidia GK106GLM (Quadro K2100M) discrete card configured via Optimus.

This architecture poses some challenges within Linux. In the Windows world Nvidia handles all complexities of both adapters, in Linux the herculean effort of the Bumblebee project allows you to tackle the complex topology and have a usable system.

WSL 2 Cisco AnyConnect Networking Workaround

Overview

WSL 2 uses a Hyper-V Virtual Network adapter. Network connectivity works without any issue when a VPN is not in use. However when a Cisco AnyConnect VPN session is established Firewall Rules and Routes are added which breaks connectivity within the WSL 2 VM. This issue is tracked WSL/issues/4277

Below outline steps to automatically configure the Interface metric on VPN connect and update DNS settings (/etc/resolv.conf) on connect/disconnect.
