The title of this post speaks for itself: “What every developer should know about TCP”. Nothing mind-blowing, just a nice reminder.

What every developer should know about TCP
Why do you need to place your servers geographically close to your users? One of the reasons is to achieve lower latencies. That makes a lot of sense when you are sending short bursts of data that should be delivered as quickly as possible. But what about…
HTTP is old, and over the ages lots of strange and interesting things had found it’s way into protocol. You’ll find more details in this post. Teaser:
- no-cache header actually means do cache
- What are the 1XX codes used for?
- Every websocket depends on the same UUID 258EAFA5-E914-47DA-95CA-C5AB0DC85B11. What?

A bunch of links about DNS have piled up, let's start with them. The 1st one - a talk on what's DNS, how it works, how to poke it, and what the request and response look like.

And here you'll find a step-by-step guide to implementing your own toy DNS resolver in python. Exercises at the end are entertaining too!

And the last one: why it's hard to debug DNS issues, a bit of rant on hardly human-readable output of some tools, and advice on how to approach such tasks.

The original idea behind Proof-of-Work was to fight email spam. Small computation puzzle is barely noticeable when you want to send a single message, it becomes rather slow and expensive in case of mass email. It's nice to see that Tor now uses adaptive PoW defence to fight DoS attacks.
