BLM – Black Lines Matter


Oct 16

I’m getting old — 50 earlier this year — and my eyesight is failing. Seriously, I bought some of those old man reading glasses from Walmart. You know the ones, the “old people” ones! 🙂   Five bucks for a little old Victorian style pair of readers that perch on the end of your nose and and let us old programmers read comfortably for a change (without squinting or holding things out at arms length)…. but I digress…

Last week I was grinding away writing some RPG OA Screen handlers. Kind of new territory for me, lots of reading web pages, scrimping code samples, editing, refactoring and many hours of nose to screen, typing and coding. I had a slight head ache at end of a couple of days.

“Must be from squinting” I think “perhaps a darker desktop will be more relaxing on my eyes?” I decide

So, I decided to switch my desktop into a dark mode and make the fonts slightly bigger. It’s taken me a couple of days to get used to it but I like it.

If you fancy doing the same thing, you can make Windows Dark like this:

Enable Dark Mode for Windows 10 Settings and Apps

To enable the dark theme, head to Settings > Personalization > Colors.

Scroll down and select “Dark” under “Choose your app mode”.

The Settings application itself will immediately turn dark, as will many other “Universal Windows Platform” applications. However, it’s up to each developer to support the dark theme, and some applications will continue using their normal colors.


Make your IBM i Teminal Emulator Dark

Head to Edit > Preferences > Appearance > Colors (or just click the COLOR button on the toolbar)

I change the BACKGROUND color setting to Black. But it looked a little to dark so I used custom color button to set it a few clicks lighter – now its a comfortable dark grey. I also set the GREEN to use a foreground color of a white/yellow which I like the look of:

Make your Rational Developer Code Editor Dark

Take RDi to the Dark Side

First, set the main theme to dark in Window > Appearance > General > Appearance and set THEME to DARK

This will make the RDi main tool all dark but to put the code editing BODY (the LPEX editor) you also need to tweak Window > Appearance > LPEX EDITOR > Appearance and choose BLACK as the Pallette

That’s all she wrote.

Having said that I prefer a slightly lighter code entry window so I choose a light grey for my preferred colour:

Just goes to prove that #BLM really does matter 🙂
