Writing an apt proxy conf file /etc/apt/apt.conf.d/proxy.conf as below.

Acquire::http::Proxy "socks5h://127.0.0.1:1080";

Permanent WSL DNS Fix (WSL 2.2.1+)

If you're encountering ping github.com failing inside WSL with a Temporary failure in name resolution, you're not alone — this has been a long-standing issue, especially when using VPNs or corporate networks.

This issue is now fixed robustly with DNS tunneling, which preserves dynamic DNS behavior and avoids limitations like WSL’s former hard cap of 3 DNS servers in /etc/resolv.conf.

Firing up LaTex on macOS 🔥

As I'm writing this small tutorial, I assume you've read my previous one about setting up macOS, so if for any tool I'll use without explanation, look to that other article.

MacTex

The full version IS NOT MANDATORY, as in the tutorial that follows I installed the smaller version of MacTeX and proceded installing every needed dependency. Installing the complete package is about ~3.5GB of download and ~5GB on disk, the smaller one is just about 80MBs.

Click here to download the complete version or here to download the smaller version.
