My saga with tmux

3 May 2020 13:34


What I do with this I commonly set up tmux sessions when I first log onto a system, and set up some sub-terminals tied to useful tasks such as: Command sessions – I’ll always have some terminals ready to run commands Log tails – if I am debugging something, I will set up a tail …

lm – list manual pages

24 Apr 2020 09:32


I have wanted this for… probably half of my life? lm (see https://woozle.org/papers/plan9.html) apparently existed in Plan 9 many years ago; it wraps apropos (and is similar to man -k) so that instead of just listing names and sections of manual pages, it sets up the line to have the man section whatever command at …

CFEngine Alternatives

21 Apr 2020 22:24


I have been using CFEngine 2 (which is substantially different from version 3) for a great many years to manage various aspects of my home system environments, making use of such things as: Copying files, to do simplistic backups where that works Editing files to have particular content such as SSH keys, cron jobs Restarting …

PostgreSQL URIs versus Unix Domain Sockets

30 Mar 2020 15:46


I recently saw https://mydbanotebook.org/post/cant-connect/g/post/cant-connect/ which presents a nice little flowchart for debugging why you might not be able to connect to your PostgreSQL database. I was recently struggling with setting database connections inside the context of Gitlab CI, where my regression test needed to connect to a “sidecar” PostgreSQL instance. (See the repo… https://gitlab.com/cbbrowne/mahout/-/blob/master/.gitlab-ci.yml) I …

fasd – a smarter cd

22 Mar 2020 20:45


Once upon a time I used to use https://github.com/wting/autojump as a way for my systems to help me quickly navigate to my favorite Directories Of Interest. Basically, it did (and similar tools also do) the following: cd is instrumented to capture directory locations each time one visits a new directory, and store them in a …

Warring with My Tasks

8 Feb 2020 10:47


The local LUG had a talk recently about Task Warrior, which inspired me to give the tool a poke. I have had excessively fragmentary handlings of outstanding ToDo items, where I have assortedly used: Index cards to note things, but this is really ephemeral; I tend to turf them quickly, and only the most immediate …

A wee jot about Mosh

28 Jan 2020 13:41


I have been using Mosh for quite a number of years now; it is a notionally “mobile” shell that nicely supports devices with intermittent connectivity. On occasion, I have used it as an alternative protocol to ssh when using my laptops/tablets/phones to connect to shell sessions. Its main merits (to me) are that: Sessions can …
