Mark GitHub notifications as read

I've needed to do this several times to combat "ghost" notifications. These occur when a discussion is created and then deleted (e.g. for spam) before the notofication is read. You may see something like "1-0 of 4" at the bottom of the notifications page.

You can use the GitHub API client to show these notifications:

gh api notifications

To mark all notifications as read, send the API request below with curl. (Update the last_read date as needed.)

Using Jemalloc 5 with Ruby.md

For years, people have been using jemalloc with ruby. There were various benchmarks and discussions. Legend had it that Jemalloc 5 didn't work as well as Jemalloc 3.

Then, one day, hope appeared on the horizon. @wjordan offered a config for Jemalloc 5.
