A friend asked me for a way to batch-convert images into PDFs. Instead of using online converters, here's a command-line solution using ImageMagick that works on both Mac and Linux. It converts all images in a folder to individual PDFs and optionally merges them into one file.
I've been using Git for a few years now, and while it's an amazing tool, the command-line workflow can be tedious. How many times have you done this?
$ git status
# On branch master
# Changes not staged for commit:
# modified: app/controllers/users_controller.rb
# modified: app/views/users/show.html.erb
# modified: config/routes.rb
$ git add app/controllers/users_controller.rb
$ git add app/views/users/show.html.erbAll that typing! Especially when you have deeply nested file paths. I recently discovered a tool called SCM Breeze that solves this problem elegantly.
Every developer needs a good text editor. TextMate on Mac, Notepad++ on Windows, gedit on Linux – there are plenty of choices. But there's one editor that stands out: Vim.
Vim (Vi IMproved) is everywhere. It's on every Unix system, every Linux server, every Mac. SSH into a server and Vim is there. It's fast, powerful, and once you learn it, incredibly productive.
