DevToys is like a Swiss Army knife for software and web developers to help with everyday development tasks such as comparing and converting text and images, testing RegEx, formatting JSON and XML data, compressing images, etc.
It’s now late October, the clocks have gone back an hour to GMT. In Scotland the nights are fair drawin’ in—it is getting dark earlier. All the more important then to make sure I look after my sleep hygiene.
For the last 14 years I have been working mostly sitting in front of a PC. I’m also a bit of a geek so I find myself sitting in front of a PC even when I’m not being paid to do so.
For years I found it hard to get to sleep at night. It turns out that staring at computer monitor for hours is not great for your sleep. The blue light emitted by a screen affects our attention, reaction times and mood (Source) and, crucially, our sleep.
In 2009, I discovered an application called F.lux that detects where you are in the world and automatically adjusts the screen colour temperature to gradually remove the blue as the sun is setting.
