Ripgrep is a fast search tool like grep. It's mostly a drop-in replacement for ag, also know as the Silver Searcher.
helm-ag is a fantastic package for Emacs that allows you to display search results in a buffer.
You can also jump to locations of matches. Despite the name, helm-ag works with ripgrep (rg) as well
as with ag.
The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.
In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.
This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.
How to use:

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.
The correct way of creating a private frok by duplicating the repo is documented here.
For this assignment the commands are:
git clone --bare [email protected]:usi-systems/easytrace.git
FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
| local usbWatcher = nil | |
| -- This is our usbWatcher function | |
| -- lock when yubikey is removed | |
| function usbDeviceCallback(data) | |
| -- this line will let you know the name of each usb device you connect, useful for the string match below | |
| hs.notify.show("USB", "You just connected", data["productName"]) | |
| -- Replace "Yubikey" with the name of the usb device you want to use. | |
| if string.match(data["productName"], "Yubikey") then | |
| if (data["eventType"] == "added") then |
