## 简介

Julia Evans is back this week with a brand new zine about networking. It’ll be posted publicly in a couple weeks, but until then, you can get your own shiny copy just by donating to the ACLU (who have been doing a ton of awesome work!). Great idea, Julia!

# New zine: "Networking! ACK!"

HI FRIENDS. In December, I started writing a zine about computer
networking! In it, I explain everything that happens when you download
[this image](http://jvns.ca/cat.png) from the internet, in as much
detail as I can fit in 24 pages.

Have you been seeing cool drawings about networking concepts on Twitter from me, and wondering “Julia, I really want to have all of these in one place, how can I get that??”? This is what I was working on!

Here’s the (amazing) cover, by rad programmer [Lee Baillie](https://twitter.com/_lbaillie).

This zine explains:

- how packets are put together
- all the steps to download a cat: DNS, sockets, TCP connections, HTTP, and TLS
- networking notation
- networking layers
- what even is a “port”
- and more!

I’m really excited about this – I spent a really long time being confused about how any of this networking stuff worked AT ALL, and I’m hoping this zine will help some people understand a few more things.

Also I am worried about what is happening in the world this week, and I wanted to do a small thing to help.
