Hi Elixir friends, After 3 years on Hologram full-time (transpiles Elixir to the browser), I'm at a crossroads. 60+ hr weeks balancing contracts & dev isn't sustainable. Where we are & how you can help: hologram.page/blog/seeking... Even sharing helps 💜 #Hologram #Elixir #ElixirLang #BEAM #WebDev

What do we call an #ElixirLang wizard? I know a lot of people use alchemist, but lately I’ve been wondering if macromancer is the way to go…

I don’t know who needs to hear this, but don’t pull an SDK to integrate with those 3-4 third party REST endpoints. It’s not worth it. Just use an HTTP client.

Just pushed a couple changes to hex.pm/packages/kin... - Loading/success/failure states - Added a workaround for when the #Livebook is running in a non-secure context (not localhost or HTTPS) Take it for a spin and let me know if you have any issues! #ElixirLang

Note to self: always check for audio in screen captures 🤦‍♂️

Just published a small Kino component for programmatically adding copying content to the clipboard: hex.pm/packages/kin... It is truly amazing how well Livebook supports prototyping these components 🤯

Me avoiding Advent of Code solutions for days 5 and 6 until I have some time to work on them

For some reason I thought it was a great idea to solve Advent of Code Day 4 using #ElixirLang Nx and convolutions.

Elixir code parsing the puzzle input into a Nx tensor

Elixir code using the parsed input to solve Part 1 using convolutions to find the all the occurrences of XMAS.

Elixir code using the parsed input to solve Part 2 using convolutions to find the all the occurrences of MAS in an X-like pattern.

The homepage example from Bumblebee on using BERT is now running on EMLX! We should hopefully be releasing the library in the next few days. We're just missing a really small set of Nx.Backend calbacks and some housekeeping stuff

Looking for my next job! - Based in Berlin 🇩🇪, but also open to remote. - I've been most excited about #ElixirLang lately, but also open to other tech stacks(I've worked with Clojure, Rust, JS/TS) Some stuff I've worked on recently below👇. (And I'd appreciate a repost :))

Raphael Costa @costaraphael.bsky.social · 2y ago

I’m very pumped by this! #ElixirLang

folder gotchas (in the terminal) wizardzines.com/comics/folde...

panel 1: ls .. and cd .. refer to different folders if you `cd` to a symlinked folder

~/Dropbox -> ~/Library/CloudStorage/Dropbox

```
cd ~
cd Dropbox
ls ..
cd ..
```

* ls .. lists ~/Library/CloudStorage
* cd .. moves to ~

this is because `ls` is a program and `cd` is run by the shell.

The shell handles `..` differently from other programs.

`ls ~/Dropbox` will list the contents of the folder

this is annoying if you just want to look at its permissions, or where it links to

to fix this:

ls -d ~/Dropbox

panel 2: deleting a folder and recreating it with the exact same name makes everything weird

everything you do in the folder will fail with weird errors like:

$ touch newfile
touch: newfile: no such file
or directory

how to fix it:

```
cd .
```

panel 3: on Mac OS, these are not the same:

cp -R a/ b

cp -R a b

* `cp -R a/ b` merges the contents of `a` into `b`
* `cp -R a b` copies the whole folder into `b/a`

panel 4: tip: `cd -` switches to the folder you were previously in

panel 5: notes on `mv file.txt dest~

* if dest is a file: renames `file.txt`
* if dest is a folder: moves `file.txt` to that folder

Any #ElixirLang devs based in Dublin (or nearby Dublin)? Been thinking of starting a meetup… A recruiter told me I was probably the only one with Elixir experience in the area and I’m dying to prove them wrong!
