    For a good default config of zsh I highly recommend oh-my-zsh[0]. I've been using it for years and it's amazing.

    I think that in the context of this question, https://github.com/mui-org/material-ui is a more relevant answer :)

    A curated list of awesome Go frameworks, libraries and software

    Latest mention: A curated list of awesome Go frameworks, libraries and software | reddit.com/r/golang | 2021-01-27

    Nice list, but honestly you should have put the link for the original repo https://github.com/avelino/awesome-go instead of a forked and outdated repo.

  • Flask

    The Python micro framework for building web applications.

    Latest mention: Project Directory - Is there a reason not to use Blueprints? | reddit.com/r/flask | 2021-01-24

    You should take a look at Flaskr, it's the official tutorial of Flask, and it uses some blueprints.

  • Apollo-11

    Original Apollo 11 Guidance Computer (AGC) source code for the command and lunar modules.

    Interestingly enough Ansible doesn't use json when parsing the output of lscpu: https://github.com/ansible/ansible/blob/13d08d232c8b692ec79dba81c9eb83887ee554a2/lib/ansible/module_utils/facts/virtual/linux.py#L266

  • meteor

    Meteor, the JavaScript App Platform

    Latest mention: What to expect in Q1 2021 for Meteor ☄ | dev.to | 2021-01-05

    Meteor 2.0 is in works and after the winter breaks we can expect the work to pick back up, though there is still a few major things to be resolved before the final release. Also its release will most likely coincide with the release of Meteor Cloud. Most notably we this release will include tree shaking, hot module reload and upgrade to Node v14. Other things like updated logging packages MongoDB bulk insert and other smaller things are also being worked on.

  • neovim

    Vim-fork focused on extensibility and usability

    Latest mention: Is it just me or some options don't work in Lua yet? | reddit.com/r/neovim | 2021-01-27

    Every option in (neo)vim has a scope, either global, window-local, or buffer-local. vim.o only sets options in global scope, not window-local vim.wo or buffer-local vim.bo. There is a PR to add a higher level vim.opt that transparently setting the appropriate scopes: https://github.com/neovim/neovim/pull/13479

  • Scrapy

    Scrapy, a fast high-level web crawling & scraping framework for Python.

    Latest mention: Does anyone know good resources to build a web crawler? | reddit.com/r/computerscience | 2021-01-26

    I'd strongly recommend Scrapy over Selenium if OP cares about performance. It uses built-in concurrency and async operations while Selenium basically runs entire Chrome instances in the background (or FF, IIRC).

  • Home Assistant

    :house_with_garden: Open source home automation that puts local control and privacy first

    Latest mention: Zigbee Network Is Down | reddit.com/r/homeassistant | 2021-01-27

  • Grafana

    The open and composable observability and data visualization platform. Visualize metrics, logs, and traces from multiple sources like Prometheus, Loki, Elasticsearch, InfluxDB, Postgres and many more.

    Latest mention: Where is my grafana.ini (Docker) kept? | reddit.com/r/grafana | 2021-01-27

    I think you can just put your own grafana.ini file in there for grafana to pick up when you start the container. Here is a sample confit file.

  • tesseract-ocr

    Tesseract Open Source OCR Engine (main repository)

    Latest mention: How do i use matlab ocr to recognize math equations? | reddit.com/r/matlab | 2021-01-16

    The code looks fine, I think for whatever reason the 'MathEquations' network just does a poor job of recognizing the equations. The support package that includes the language is based on this open-source tessaract repo which seems to struggle with math equation recognition (at least based on this issue).

  • app-ideas

    A Collection of application ideas which can be used to improve your coding skills.

    Latest mention: Hur mår du? | reddit.com/r/sweden | 2021-01-25

    Om du vill fortsätta på app/frontend spåret och lärt dig Flutter och dart är inte steget långt till att göra en liten app. Publicera den och ha med den på cv't. En simpel app från https://github.com/florinpop17/app-ideas kan göra stor skillnad då det visar på att du har driv och vet hur man "gör klart" ett projekt.

  • Git

    Latest mention: Where is the Git repository for Git itself? | reddit.com/r/git | 2021-01-24
  • prometheus

    The Prometheus monitoring system and time series database.

    Latest mention: Troubleshooting the right way | dev.to | 2021-01-25

    It worked! Stopping Prometheus broke the active connection that Prometheus previously had with NewRelic. I wasn't aware that remote_write keeps an active connection; I was sure it just sends the data and closes the connection. Apparently, it is documented in the official changelog of Prometheus - 1.8.0 / 2017-10-06 - "..Remote storage connections use HTTP keep-alive..
