I continue to stay analog in the digital world, mainly using pen and paper. Besides pencils, I also like to use fountain pens (as well as other types of roller pens). I have tried many inks so far, and Parker Blue-Black QUINK Ink ( Amazon Link) is the best in terms of color, smoothness, and price tag. The deep, rich tone of blue-black provides an elegance that enhances my writing, making even the most everyday notes and draft ideas special.

I always thought punch cards were used solely for programming early computers, but I recently discovered that this is not the case. During my visit to the National Museum of Scotland, I encountered the Jacquard loom, invented by French weaver Joseph-Marie Jacquard in 1804. I learned that this production of patterned textiles was automated using punch cards, demonstrating their use as far back as the 1800s. I was surprised to find out about this historical application of punch cards.

I have been using MATLAB for a long time and was quite happy until switching to the first Apple Silicon M1. Matlab’s full adoption took way longer than I expected. Finally, the R2025a version starts fast, runs fast on Apple Sicions (I only tested M4 Max), and is less laggy.

I think the transition from Java is completed since no Java version is detected on the version.

bench(3) returns incredible results (below). I hope Matlab will support it natively on other platforms that use Arm CPUs.
