How to Sell Elixir AGAIN (2023)

Presented by Evadne Wu at Code BEAM Lite in Stockholm, Sweden on 12 May 2023

Synopsis

We have celebrated 10 years of Elixir and also nearly 25 years of Erlang since the open source release in December 1998.

Most of the libraries that were needed to make the ecosystem viable have been built, talks given, books written, conferences held and training sessions provided. A new generation of companies have been built on top of the Elixir / Erlang ecosystem. In all measures, we have achieved further reach and maturity than 5 years ago.

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

Legend:

• ➖ poor (impossible or very hard to achieve)
• ➕ good (possible but requires some dancing)
• ✔️ excellent (very easy to achieve/have)

PC stands for parser combinators and PG — parser generators.

Property	Generators	Combinators	Description
Power	✔️ LALR	➕ LL(∞)	PC can't handle left-recursive grammars (though, there's some article¹...).

Source: andOTP/andOTP#66

Hello, congratulations on such a nice OTP app. It has everything I want in an app, so I migrated my codes from FreeOTP to andOTP. I wrote a short script to do this.

To run the script, get the tokens.xml file from the FreeOTP directory on the phone, run the script with the filename as a parameter (./freeotp_migrate.py tokens.xml), and the script will output an andOTP-compatible plaintext JSON file. Just restore that and you're done.

Here's the script, released under the MIT license:

# This bash script converts every .xm .mod .it files to mp3 using VLC Media player
# Basically it supports every media format that VLC supports, and converts it to mp3
# if you comment out the file type checking line below.
# Usage:

// Example testing sketch for various DHT humidity/temperature sensors
// Written by ladyada, public domain

#include "DHT.h"

#define DHTPIN D7     // what digital pin we're connected to

// Uncomment whatever type you're using!
//#define DHTTYPE DHT11   // DHT 11
#define DHTTYPE DHT22   // DHT 22  (AM2302), AM2321

echo  "$items"|while read -r rem # I pipe the list because otherwise the loop will treat blank space as delimiter

    rm_time=$(($(date +%s --date "`echo $rem | sed -n 's/^\([0-9][0-9]:[0-9][0-9]\)-.*/\1:00/p'`") - 600)) # this command extracts the starting time of the event, and convert it to EPOCH, and subtract 10 minutes from it.
    rm_time=`date +%H:%M --date @$rm_time` # This converts EPOCH back to human readble form
