Slate is a great code documentation setup based on Middleman. I’ve been playing with it a bit and like it a lot since it’s based on Padrino and very easily extended. However, I had this problem that every page reload would take roughly five seconds. It turned out the problem is the CSS compilation happening… Continue reading Make Slate/Middleman recompile CSS faster
A valuable debate arose from my last post about extending inherited. Matz suggested using an anonymous class generated by a method from which the actual class inherits. This is a common pattern found in many gems, even my own. As a reminder, the behavior I want is as follows. Note that the whole point of… Continue reading Dear Ruby (2): The Functional Inherited Hook
With most of my code becoming more and more stateless and functional, I haven’t given up leveraging Ruby’s excellent way of defining declarative APIs and DSL. Ruby is just too good at that. However, I am missing a crucial tool in Ruby: being able to pass dynamic arguments to the inheritance, exactly the way I… Continue reading Dear Ruby (1): What about Arguments when Inheriting?
I was playing with the omniauth-github gem in a Trailblazer/Sinatra application with the basic setup as described per README. When hitting /auth/github manually, something happened, but then I’d get an exception on my side saying the following. ERROR — omniauth: (github) Authentication failure! csrf_detected: OmniAuth::Strategies::OAuth2::CallbackError, csrf_detected | CSRF detected E, [2017-12-10T19:09:08.951604 #9111] ERROR — omniauth: (github)… Continue reading Solved: omniauth-github fails to authenticate
Audacious in Ubuntu doesn’t have the “Global Hotkeys” plugin activated per default. If you enable it, the play/pause key on Apple keyboards (probably on others, too) will start the song, but then restart it when tapped again. The solution is to set the XF86AudioPlay button to “Pause/Resume”.
Data backups are important. USB sticks with 256GB or more have become affordable, and are a good way for backups. I wanted mine to be encrypted. Since I usually dump my entire home directory to the backup medium (my new USB drive), indiscreet, or, let’s call it sensitive data like passwords and SSH keys will… Continue reading Hard-drive Backups to USB drives using Encryption, on Ubuntu
Brand-new SD cards sometimes need to be formatted to VFAT to work properly on Linux. sudo fdisk /dev/mmcblk0 > t select “b” for FAT32 > w This will convert the first partition to FAT32 and write the new partition table to the SD card. Make sure to select the top-level disk with fdisk, and not one… Continue reading Formatting an SD Card to VFAT on Linux
