I’m reading this book Machine learning in Elixir so I tested elixir livebook on my macos using the .dmg installer , and it’s running smoothly. I decided to install it locally on my computer to know what is happening behind the scenes, so it’s straightforward; only need to run these commands: # install or update rebar and hex mix do local.rebar --force, local.hex --force # install as executable livebook mix escript....
In my current work, I’m using (abusing) of the ruby safe operator &, which is a native implementation of the null pattern, for example, in a chain of messages: user.billings.first.cost It could be thrown an error when for example the billings of a user is empty and first returns a nil object and then nil.cost creates an Exception. With the safe operator & this avoids the error: user.billings.first&.cost # => 5....
Ignoring files or directories in dropbox is a hard thing, I thought it has like git, a .gitignore to config that, but no, we need to do a command for each file/dir, for example to ignore the files that creates a lightroom catalog (.lrcat) we need to do: xattr -w com.dropbox.ignored 1 /Users/username/Dropbox/lightroom/2021-v10\ Previews.lrdata xattr -w com.dropbox.ignored 1 /Users/username/Dropbox/lightroom/2021-v10\ Previews.lrdata xattr -w com.dropbox.ignored 1 /Users/username/Dropbox/lightroom/2021-v10\ Helper.lrdata and to not longer ignore files we need this command:...

Recently I started to work with Docker in a project, and I ever use vim-test to run test using vim, now to integrate in current docker workflow we need to configure vim-test. For example to configure to run rspec test inside app: let test#ruby#rspec#executable = 'docker-compose exec -e RAILS_ENV=test app rspec' to run inside to already running app docker container. It is very important to add -e RAILS_ENV=test to send envinroment variables and set test env inside the rails app....
In a project I had troubles triying to install mysql2 gem with a older version of mariadb installed via homebrew. the solution is to send the path of the installation. gem install mysql2 -- --with-mysql-config=$(brew --prefix mariadb@10.2)/bin/mysql_config
The idea of this post is to configure correctly the support of python3 on neovim, let’s start. first this configuration is using macOS, by default python3 is installed on macOS and the default route of the executables are: which python3 # => /usr/bin/python3 which pip3 # => /usr/bin/pip3 And that’s it! but normally if you are using homebrew you also installed the python3 using a formula, personally I do not to recomend that but it will work....
The problem is with RVM and renv and not with asdf, so my first suggestion is to change to asdf if you keep with RVM: install older versions of ruby <2.3 with support for openssl 1.0x you can follow these instructions: # before you install command line tools and gcc xcode-select --install brew install gcc # installation procedure cd /usr/local/src curl -O https://www.openssl.org/source/openssl-1.0.2t.tar.gz tar xzf openssl-1.0.2t.tar.gz cd openssl-1.0.2t ./Configure darwin64-x86_64-cc make sudo make install export LDFLAGS=“-L/usr/local/ssl/lib” export CPPFLAGS=“-I/usr/local/ssl/include” export PKG_CONFIG_PATH=“/usr/local/ssl/lib/pkgconfig” rvm reinstall 2....
Context The idea is to develop the same requirement as devise describe in their guide: The project is using the admin_user approach and sets the default setup included on activeadmin. (NOTE) One other recommended solution is to migrate the admin_user model to user and configure devise normally as a separate engine. Guide If you haven’t already, enable the confirmable module If you haven’t already, follow the Devise instructions for configuring views, install in app/views/active_admin/devise...
