I'm a huge fan of the US Braille Institute's Atkinson Hyperlegible font. This blog is typeset in it, and I think it looks gorgeous. It's also specifically designed to be readable to people with visual impairments: Atkinson Hyperlegible differentiates common misinterpreted letters and numbers using various design techniques: There's only one problem, the font was released a few years ago and…

Yesterday, I revealed my disappointment in being unable to print a bookcase. Today I revel in my cleverness at coming up with a solution! I decided to create a photo-mosaic of a nice photo of me and my wife - using all our book covers. The Result Close Up The image was printed on high-quality canvas - which gives it a pleasing texture and isn't too glossy. Zoomed in, this is what it looks…

I'm using an old Android phone as a webcam. The camera lens is great, the DroidCam software is nifty, but the Android OS behind it is old and dying. My phone often needs rebooting. Which means that the app also needs restarting. The phone's screen faces away from me, so I can't interact with it. This is a quick guide (mostly notes to myself) about rebooting and starting an app from the command…

I've moved to s a standing desk. So now, obviously, I need something useful to do with my feet! It's time for a USB powered set of foot pedals!

The switches have little tactile nubs on them and are well sprung. These aren't Cherry MX quality s…

So when a pal was selling theirs cheap, I leapt at the chance to play with one. I've tried to love it - I really have - but it makes too many compromises, in my opinion.

They already got your money, so fuck you for expecting any further updates. Here's their message: We express a sincere gratitude for your patronage to LG 360 CAM Manager Service. Due to changes in our operation policies, LG 360 CAM Manager…

(Mostly notes to myself.) If you have a lot of images in a directory, and want to quickly make an image montage, here's how to do it on Linux using ImageMagick. First up, this command finds all JPG file, then resizes them so they fit in a maximum box of 256x256, then sets the quality to 75%, then saves them as JPGs: find ./ -type f -iname "*.jpg" -exec mogrify -verbose -format jpg -layers…

How do you quickly insert a 💩 emoji when using your laptop? I just type ScrLck, p, o, o! What is this 🧙♀️ craft? In your keyboard settings, you should see an option like this: You can set the "Compose" key to be anything you like. Personally, I use the otherwise-useless Scroll Lock button.
