6 min readTo enforce a "no spaces in filenames" policy in Git, you can configure a git hook that runs checks on file names before they are committed to the repository. This can be done by creating a pre-commit hook script that uses regular expressions to check for spaces in file names and prevent the commit if any are found. The script can also provide a helpful error message to the user indicating that spaces are not allowed in file names.

This can include removing old logs, caches, and temporary files that are taking up space. Additionally, uninstalling unnecessary software or packages can help decrease the overall size of the VM image.Another way to reduce the size of the Vagrant VM image is to compact the disk. This can be done by zeroing out unused space on the disk and then shrinking the disk image.

6 min readTo stream into a file in Elixir, you can use the IO.binwrite/2 function from the File module. This function can be used to stream data into a file by continuously writing chunks of data. Here is an example code snippet that demonstrates how to stream data into a file in Elixir: {:ok, file} = File.open("output.txt", [:write]) Enum.each(1..100, fn num -> IO.binwrite(file, to_string(num) <> "\n") end) File.
