The Sound Of Software

tl;dr: “Sound is an outcast in Software Design. We may embrace the aesthetics of animation and visuals, but sound is different. It’s intrusive. Unlike visuals on a screen, you can’t look away or ignore it... If you haven’t worked with sound before, it may be difficult to know where to start. When should you use it? How do you create it? How do you shape it? How do you even talk about it? Let's get in it.”

In Loving Memory Of Square Checkbox

- Nikita Prokopov tl;dr: "But despite all this chaos and temptation, operating system vendors knew better. To this day, they follow The convention: checkboxes are square, radio buttons are round. Maybe it was part of their internal training. Maybe they had experienced art directors. Maybe it was just luck. I don’t know, it doesn’t really matter but somehow they managed to stick to the convention. Until this day."

Communicate Design Tradeoffs Visually

- Tim Lyakhovetskiy tl;dr: “A goal of any written design or project proposal is to present and evaluate alternatives. However, documents that include multiple solutions can be difficult to read when the qualities of each solution are not clearly expressed. A common approach to simplifying proposals is to use “pros and cons” for each alternative, but this leads to biased writing since the pros and cons may be weighed differently depending on the reader’s priorities.” Tim shows us how to color code these tradeoffs to make it easier for readers to parse ideas.

Hey, Computer, Make Me A Font

- Sergey Tselovalnikov tl;dr: “This is a story of my journey learning to build generative ML models from scratch and teaching a computer to create fonts in the process.” FontoGen is a generative ML model project that crafts type fonts based on user descriptions. The author delves into the complexities of text-to-SVG generation and the intricacies of maintaining stylistic uniformity across glyphs. Drawing inspiration from the IconShop paper, a sequence-to-sequence model was employed, using text embeddings from BERT and font embeddings from tokenized glyph shapes.

Everything That Uses Configuration Files Should Report Where They're Located

- Chris Siebenmann tl;dr: Chris regularly interacts with various programs, each of which has its configuration files in different locations, sometimes system-wide, other times user-specific. Given the variability and their infrequent interaction with some programs, they struggle to remember the configuration file locations, which can lead to time-consuming searches through manuals or documentation. Their proposed solution is for programs to offer an easy method, preferably via command line, to report the location of their configuration files.
