Some things on Prometheus's new feature to keep alerts firing for a while

=> ↺ Some things on Prometheus's new feature to keep alerts firing for a while

The obvious use of 'keep_firing_for' is to avoid having your alerts flap too much. If you set it to some non-zero value, say a minute, then if the alert condition temporarily goes away only to come back within a minute, you won't potentially wind up notifying people that the alert went away then notify them again that it came back. I say 'potentially', because when you can get notified about an alert going away is normally quantized by your Alertmanager group_interval setting. This simple alert rule setting can replace more complex methods of avoiding flapping alerts, and so there are various people who will likely use it.

Wordsmith on the Linux command line with dict

=> ↺ Wordsmith on the Linux command line with dict

As a writer, I frequently need to determine the correct spelling or definition of words. I also need to use a thesaurus to find alternate words that may have a somewhat different connotation than the one I might otherwise use. Because I frequently use the Linux command line and text-mode tools to do much of my work, it makes sense to use a command line dictionary.
I really like using the command line for a number of reasons, the primary one being that it is more efficient for me. It is also far more comprehensive than any one or multiple physical paper dictionaries, could ever be. I have been using the Linux dict command for many years and I have come to depend on it.
