My new laptop has a 4K monitor and my tool of choice for writing my Arduino books, Lyx, always displayed the toolbar icons as “so very tiny, it is hard to see the damned things!” After much experimenting with the monitor’s scaling, fractional scaling and such like, I found QT_AUTO_SCREEN_SCALE_FACTOR which should fix things. I tested: 1 2 export QT_AUTO_SCREEN_SCALE_FACTOR=1 lyx & and yes, the icons were now usable. Hooray. I just need to make this permanent.

So, after many years of happy blogging – some years more often than others – I’ve finally run out of hosting space with my cheap and cheerful hosting provider. I thought about just paying for more storage, but with retirement and the closing of my – and by “my” I mean, “mine and MrsD’s” IT Company – I decided that a full Wordpress website wasn’t really necessary, what with its need for a database such as MySQL and PHP.
