This blog post will be slightly different than the usual Mathematics/CompSci focused posting.

When I used to study architecture, because I didn’t own a computer that had Windows installed on it, I would do many of the drawings required for the courses by hand. There I learned the absolute value there is in using tools which were made specifically for a single task. For example, I started out using drawing pencils (the ones that come in different hardness) to do the drawings. You’ll notice eventually that although the hardness is very important for drawing, the thickness with which the lines get made is equally if not more important. This meant that using regular wooden drawing pencils wouldn’t cut it, they would get blunt and thicken too fast. This is where mechanical drawing pencils came in. To this day, mechanical drawing pencils are my go-to when writing things down because of their versatility and resilience. Something else I’ve noticed about owning a single one of these pencils for the past 8 years is: this pencil might be plastic in some places and metal in others, but the used look of it looks very nice.
