Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.

Flamegraph of your asciidoc books

I wrote a very primitive script to produce a flamegraph out of a number of asciidoc files. See this blog post for some idea of the result.

WARNING: It's heavily taylored to my own setup, so not sure it'll work directly with yours, or you might have some customization to do. (If there's enough interest I could do a more general script / Dockerfile.)

How to play ASCII-Art Star Wars offline

Following will teach you how to play the "easter-egg" (which actually isn't, but many people describe this as an easter egg) of ASCII-Art Star Wars (or Star Wars in terminal/telnet, whatever), the one you normally starts like this:

$ telnet towel.blinkenlights.nl
  1. Before you start, ensure Node.js is installed.
  2. Navigate to www.asciimation.co.nz, the original home of that ASCII-Art Star Wars.
  3. Press F12 to open developer tools.

'Users hate change'

This week NN Group released a video by Jakob Nielsen in which he attempts to help designers deal with the problem of customers being resistant to their new site/product redesign. The argument goes thusly:

  1. Humans naturally resist change
  2. Your change is for the better
  3. Customers should just get used to it and stop complaining

There's slightly more to it than that, he caveats his argument with requiring you to have of course followed their best practices on product design, and allows for a period of customers being able to elect to continue to use the old site, although he says this is obviously only a temporary solution as you don't want to support both.

statement on event-stream compromise

Hey everyone - this is not just a one off thing, there are likely to be many other modules in your dependency trees that are now a burden to their authors. I didn't create this code for altruistic motivations, I created it for fun. I was learning, and learning is fun. I gave it away because it was easy to do so, and because sharing helps learning too. I think most of the small modules on npm were created for reasons like this. However, that was a long time ago. I've since moved on from this module and moved on from that thing too and in the process of moving on from that as well. I've written way better modules than this, the internet just hasn't fully caught up.

@broros

otherwise why would he hand over a popular package to a stranger?

If it's not fun anymore, you get literally nothing from maintaining a popular package.
