Welcome to another issue of Haskell Weekly! Haskell is a safe, purely functional programming language with a fast, concurrent runtime. This is a weekly summary of what’s going on in its community.
Take the Developer Nation survey and share your views about the most important coding skills, tools, and platforms for 2022. You will get a virtual goody bag with free resources, plus a chance to win an iPhone 13, a Nintendo Switch, licenses, Amazon vouchers and more.
Databass, Part 2: Inserting into the database by Joseph Morag

A Christmas Story by Moritz Angermann
The following is a story about me, stumbling around ghc, fileformats, libc’s, linking and debuggers and overcoming challenges and finding bugs, trying to get the bare minmum of an iOS and Android toolchain to work for compiling Haskell code into libraries to be used on aarch64 mobile devices.
Scoped effect resources for Polysemy by Torsten Schmits

We are making a secure, open-source messenger and video conferencing app. Our backend is one of the oldest commercial Haskell code bases around, but we are constantly modernizing it and have recently adopted libraries like servant and polysemy. Plus we’re really nice people! :) If you feel your seniority lies in Software development, but not in Haskell specifically, we’d still like to look at your application. We have an office in Berlin, but also many remote team members.
