TTT Part 38 of n – TMUX (A Screen Alternative)
Filed Under Computers & Tech on July 11, 2020 | Leave a Comment
Since we covered the screen command in instalment 36, it has been deprecated in Red Enterprise Linux 8, and the official advice from Red Hat is to transition to the tmux command. Having been a fan of screen for years, I was skeptical, but I shouldn’t have been — tmux can do everything screen can, it can arguably do it better, and, it can do much more than screen ever could!

Generating SSH Keys on Windows with PuTTYgen
Filed Under Computers & Tech, Security, System Administration on February 26, 2020 | 1 Comment
In instalment 30 of the Taming the Terminal series I showed how SSH keys can be used to more securely and conveniently connect to servers. The instructions in that instalment are for Linux-like OSes (including MacOS) where the standard OpenSSH tools are available.
Windows doesn’t ship with OpenSSH (or indeed any SSH implementation), so Windows users who want to SSH need to install some kind of additional software. With Windows 10 there is the obvious option of installing the Windows Subsystem for Linux, but people may prefer a GUI experience. The obvious choice for Windows users is the venerable free and open source PuTTY suite of tools.
The PuTTY SSH client itself is easy to use, and if you install the full suite of apps via the MSI installer (available on their download page) you’ll also get a GUI for generating SSH keys named PuTTYgen.

PBS Tidbit 1 of Y — Display Values are not Data!
Filed Under Computers & Tech, Software Development on February 8, 2020 | 2 Comments
Listener @lbutlr pointed out on Twitter that the sample solution to the challenge set in PBS 88 as I originally posted it in PBS 89 had a bug — it sometimes got its maths spectacularly wrong!
It’s important to note that the bug did not affect all currencies, just some currencies.
The line of code for doing the currency conversion is supremely simple:
|
1 |
const convAmount = baseAmount * rate; |
How on earth can there be a bug that is something so simple that only manifests for some currencies but not for others?
