Time to get those animations working. Ever since SwiftUI came out I’ve been a big fan. Finally no more storyboards, no more duplicate nonsense of half building in code and half in a GUI. But animations lately reminded me that there’s still a lot of less than obvious tricks you…

Easily choose parameters for convolution layers in neural networks. The goal is to help you design convolution layers, in case you are like me and can’t think about things without a pretty picture. Here you can find the calculator online: Convolution calculator for CNNs Easily design convolution layers for neural networks.www.oliver-ernst.com You can also embed it on your website — it’s…

Clean up your teeming reading list. Here is the GitHub repo. with the script. If you are like me, your reading list is overflowing. Mine is over 1000+ entries. I use it daily to quickly remind myself of useful websites I’ve found, but I never bother to clean it up…

Take away the ugliness of expectations for dealing with completions using async-like helpers and lambda functions. I wish async were ready in Swift. OK, it’s ready as of Swift 5.5! But only for iOS 15 (at the time of writing), which doesn’t really help much for most app development, since…

Extensions I keep coming back to. Enums are great. In many languages enums arise when we don’t have a binary (boolean) option, but rather one of many. In Swift they simplify even binary events by letting you make otherwise optional variables as non-optional. But one of the coolest parts about…

Finally, something that works. Maybe it’s Raspberry Pi OS or maybe its Raspbian or maybe its NOOBS. You flashed it onto a 32GB SD card without thinking, and now you want to clone it onto another card. Only, your other card is only 16GB. This should work if your card…

Gaussian graphical models are defined by the structure of the precision matrix. From a fixed structure, how we estimate the values of the precision matrix? I will show you two slightly different problems using TensorFlow. You can see the GitHub repo for this project here. The corresponding package can also…

The awesomeness of CI is that docs and tests run automatically. Requiring that tests pass on merges is probably the most critical CI feature to large projects. The pain of CI for Swift is that for simple things like generating documentation, we have to build the entire package/app, which usually…
