Fzf To Clipboard On Windows

Been using the great fzf CLI utility lately. Here's a neat trick to copy the search result to the Windows clipboard:

fzf | clip

The resulting copied text tends to include a carriage return however. To remove it, either add the --print0 option to the fzf command or permanently make it a default option using the FZF_DEFAULT_OPTS environment variable.

The use-case for this trick is to quickly find a file within a project, copy the path …

Installing HospitalRun On Arch Linux

Date Tags software

I recently installed HospitalRun on Arch Linux using the official instructions available here. Everything went well except for step 5 involving script/bootstrap which required the following changes:

Changelog Structure

I recently changed my preferred structure for changelog files. Examples of the old structure are shown in the Qprompt changelog while the new structure is shown in the PopPage changelog.

The new structure is based on suggestions from Keep A Changelog. Liking the clarity and brevity of this style, I updated the changelog section in the Unified Style Guide to incorporate their suggestions.

While I don't plan to update old changelogs, new changelogs will definitely …

As of PopPage 0.3.1, there …

DevLog - Qprompt

Qprompt is a simple CLI library for Python that I have slowly working on for about two years now. It provides basic typed prompts and menus in a CLI environment along with some additional convenience functions. Recently, I added a feature that allows prompt inputs to be automatically entered via stdin; I have found this feature to be enormously helpful. Let's look at an example use case.

Question Drilldown - Kalman Filter

The Topic

For this drilldown, we will take a very high-level look at a technique used in robotics, control systems, and any other applications involving sensors: the Kalman Filter.

NOTE: No math will be covered in this article. There are plenty of great resources for learning the math behind the Kalman Filter. Think of this article as a primer.

The Q&A

What is a Kalman Filter (KF)?

The KF is an algorithm used to …

Question Drilldown - Processes, Threads

This is the first post using a format that I have been wanting to try out for a long time. The idea is to catalog the questions that might be asked when first learning about a topic. By reviewing these questions, hopefully newcomers can learn a great deal and the more experienced can brush up a bit. The goal is not to exhaustively review every detail on the topic but rather provide just enough information …
