Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

A quick guide on how to setup X11 forwarding on macOS when using docker containers requiring a DISPLAY. Works on both Intel and M1 macs!
This guide was tested on:
- macOS Catalina 10.15.4
- docker desktop 2.2.0.5 (43884) - stable release
- XQuartz 2.7.11 (xorg-server 1.18.4)
- Macbook Pro (Intel)
Using newer compiler versions and the optimizer gives gas optimizations and additional safety checks for free!
The advantages of versions 0.8.*
over <0.8.0
are:
- Safemath by default from
0.8.0
(can be more gas efficient than some library based safemath). - Low level inliner from
0.8.2
, leads to cheaper runtime gas. Especially relevant when the contract has small functions. For
L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns
Compress 1K bytes with Zippy ............. 3,000 ns = 3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns = 20 µs
SSD random read ........................ 150,000 ns = 150 µs
Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
/!\ Be very carrefull in your setup : any misconfiguration make all the git config to fail silently ! Go trought this guide step by step and it should be fine 😉
- Generate your SSH keys as per your git provider documentation.
- Add each public SSH keys to your git providers acounts.
- In your
~/.ssh/config
, set each ssh key for each repository as in this exemple:
These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.
