Hello and welcome to the Julia community!

This is a good place for beginners to start. Feel free to read about common words we use in our glossary, how to make a PR, and much more.

Happy Hacking!


Hello, I have started this document as a handy glossary to point to for beginners. Generally intended for English as a Second Language Speakers or new users of online forums and the Julia Community in general.

Terms Meaning
foo / bar / bazz These terms are used to give an example of what is being discussed, and the names don't actually mater. For example, foo(bar.txt) means that there is some function that will be called on a text file, but the names don't really matter at the moment.
AFAIK As Far As I Know
MWE Minimum Working Example. A piece of code to reproduce your problem on someone else's machine .
LGTM Looks Good To Me
YMMV Your Mileage May Vary, an abbrevaited way to say "Your experience may be different than mine".
IIUC If I Understand Correctly
AFAIK As Far As I Know
IANAL I Am Not A Lawyer
PR Pull Request (see Git)
REPL Read Evaluate Print Loop, also known as that terminal / dark window when you open up Julia for the first time. Very useful for experimenting with you Julia codes.
TIL Today I Learned
GC Garbage Collector. An algorithm that helps manage the memory needed for Julia to run.
LLVM Julia's compiler. As a beginner, its enough to know that a compiler takes code, transforms it, and ideally makes it faster.
GSOC Google Summer of Code. Happens once a year in June - August. Google pays students to code in Julia
COC Julia's Code of Conduct.
Slack An online chatting forum that permits talking in different #channels, with emojis and some code formatting. Messages get auto deleted after a while.
Discourse Usually suited towards longer form discussions.
Zulip An online chatting forum like Slack, but open source, and permanent history.
GitHub / issue tags A web page where most of Julia codes are freely hosted. People usually discuss code designs and submit Pull Requests here.
Meetups When Julians meet each other in person. Usually location based with some scheduling. See the calendar for your local ones
Triage A call with Julia devs who focus on internal issues of how Julia works. Open to all, heavy technical knowledge.
Community Calendar A place where meetups, calls, conventions and other Julia-related events are announced. Link is here
JuliaCon A once a year conference that happens somewhere in the world. People present posters, presentations and share their code. Almost all material is easily accessible on youtube.
Ship it! A phrase to publish some code, usually with some bravery.
#general A chatting channel on Slack/Zulip where things of general Julia interest are discussed.
#random A chatting channel on Slack/Zulip where things are more casual and people post about random things, like the latest computer chips or a cool new video gets shared
#helpdesk A place where you can ask even the most basic questions about working with Julia and volunteers will try to help. Very useful to read how to get help before. Also consider that people do this for free, so please be kind.
#community A channel to coordinate community events like meetups, conferences, etc.
#diversity A place to discuss efforts towards the inclusion of marginalized people within the Julia community
Moderator Moderator here on Discourse. People who help keep spam away and interactions friendly and productive.
Steward Julia long time community members who take actions about faults with the CoC by community members. Not their day job, not their favorite job, not a thankful job, but rewarding for the community at large since this almost all online communities need to enforce some rules.
bump (an issue) To recomment on a github issue or topic so that it gains attention again. Usually well intentioned if someone committed to working on the code and hasn't reported back in a while and it would be useful to know the current status of it.
ping To mention someone like @this so that they get a notification.
necroposting To find a post in a forum like Discourse that hasn't been touched upon in quite a while and try to restart the conversation. Usually not seen in a positive light, some topics need to be moved on from.
