Better Dev Link

Issue 66 - Sep 10, 2018

This issue may a bit Go heavy because the GopherConf just finished. I have pick some of topics that I think will boost your knowledge regardless you are writing Go or not.

Select Star SQL

This is an interactive book which aims to be the best place on the internet for learning SQL. It is free of charge, free of ads and doesn’t require registration or downloads. It helps you learn by running queries against a real-world dataset to complete projects of consequence. It is not a mere reference page — it conveys a mental model for writing SQL.

Repeat yourself, do more than one thing, and rewrite everything

Splitting things up into simple units can lead to awkward composition and struggling to coordinate cross cutting changes. Avoiding rewrites means they’re often left so late that they have no chance of succeeding.

Cryptography 101: How a Symmetric Key Exchange Works (Basically)

Applying Seccomp Filters at Runtime for Go Binaries

Seccomp is a feature provided by the Linux kernel and is used to control the syscalls made by a process. Seccomp has been implemented by numerous projects such as Docker, Android, OpenSSH and Firefox. In this blog post, I am going to show you how you can implement your own seccomp filters, at runtime, for a Go binary on your Dyno.

Implementing a Network Protocol in Go

You will learn a lot about network as well

Interactive Calculus via LaTeX

This is a very cool project. They use this Tool to build interactive math course from latex. This paritcular course use this Source. You can also checkout other Linear algebra. Time to dust off some math.

Who left open the cookie jar?

A comprehensive evaluation of third-party cookie policies. Testing across 7 browsers and 46 browser extensions, the authors find that for virtually every browser and extension combination there is a way to bypass the defense mechanisms built into browsers that seek to protect against user tracking and cross-site attacks.

Tuning PostgreSQL Database Parameters to Optimize Performance

Percona has been focus on MySQL before but started to contribute lots of PostgreSQL knowledge. Checkout Tune Linux Kernel Parameters too.
