Search for a command to run...
I have over 40 years of programming experience using a variety of languages over the course of my career to develop real-time solutions for real-world problems.
Keyboards connect us to the world and, as a keyboard enthusiast, I am searching for the ideal keyboard.

Looking at an article for the book “Gist of Go: Concurrency,” I also stumbled across a reference to “High-precision date/time in SQLite” written by the same author, Anton Zhiyanov. I use SQLite in man

Modern Fortran: Tricks of the Software Engineering Trade by Damian Rouson Sometimes I think I'm one of the few programmers routinely using Fortran long after my Engineering studies too many years ago. As such, I'm pleasantly surprised when a new book...
Make GIT a Habit
I have Ubuntu Linux 22.04 installed on my Windows machine. I was working through an example from a book that required running the "time" command. However, the syntax was wrong. Since time is not a command I use frequently, I wanted to understand the available options and why the syntax failed.
The terminal command session and outputs below are self-explanatory:
$ type -a time
time is a shell keyword
time is /usr/bin/time
time is /bin/time
$ /usr/bin/time
Usage: /usr/bin/time [-apvV] [-f format] [-o file] [--append] [--verbose]
[--portability] [--format=format] [--output=file] [--version]
[--quiet] [--help] command [arg...]
$ /usr/bin/time --version
GNU time 1.7
$ /bin/time
Usage: /bin/time [-apvV] [-f format] [-o file] [--append] [--verbose]
[--portability] [--format=format] [--output=file] [--version]
[--quiet] [--help] command [arg...]
$ /bin/time --version
GNU time 1.7
I can only attribute the syntax error to an "errata" moment in the book, as only two options begin with a single - and -- must precede all the remaining options.
Almost every book published refers to the "errata" page to report or review known errors. Unfortunately, discovering them as you work through a book introduces unexpected and often time-consuming frustration.
Perhaps it's time for a different kind of eBook - one that has a "version control" mechanism that triggers an "Upgrade Available" that automatically notifies readers of changes to the text or code.
If we can do it with code, there must be a way with plain text!
