We released another new app: QR Friend.

I was using an older Android phone for a while, without access to Google Lens. That meant I needed to get an app for reading QR codes. But I couldn’t find a decent one on Google Play. They were either outdated, or riddled with ads and unnecessary features. So we built one ourselves.

It is not uncommon, for example, to hear “teachers” make statements such as, “Oh, I taught them that, but they didn’t learn it.” There is no utterance made in the Teachers’ Room more extraordinary than this. From our point of view, it is on the same level as a salesman’s remarking, “I sold it to him, but he didn’t buy it”—which is to say, it makes no sense. It seems to mean that “teaching” is what a “teacher” does, which, in turn, may or may not bear any relationship to what those being “taught” do.

Writing code faster or working longer hours is not the fastest way to get a project done because you can only linearly scale up how fast one can program. On the flip side, there’s nonlinear savings that can be had by reducing the amount of work you need to do in the first place. Thus, you should write less code rather than trying to write code faster.

We (Bloco) have done a major update of the Caderno Android app, 12 years after its release. It includes a new icon, a big redesign, and new features like search, backup and dark mode. Plus we’re finally testing revenue models for the app.
