Background: Computer speakers can play high-frequency sounds that a dog can hear, but a human cannot. (This will be important later.) The Issue: People often wish they spent less time casually browsing / “doom scrolling” on the Internet. Unfortunately, it’s a hard habit to break! Proposal: This solution is very simple: an operating system can…

Background: In the year 2023, machine learning based chatbots finally became superior to the average human*. One interesting feature of these chatbots is that they provide the ability for the user to regenerate an answer. Here’s how the ChatGPT system handles answer regeneration: Not bad at all!

Background: In the early 2020s, the appeal of short (< 1 minute) videos became widespread, with TikTok, YouTube Shorts, Instagram Reels, and other services vying for market share. (Surprisingly, the earliest major entrant into this genre, Vine (https://en.wikipedia.org/wiki/Vine_(service)), completely failed and was shut down in 2017). The Issue: Unfortunately, the popularity of “bite-sized” videos has…

Background: It’s easily possible to receive an overwhelming number of phone notifications these days. Typically, this is a mix of emails, text messages, multiple messaging apps, and the occasional demanding apps spamming you with notifications that “you earned 10% off your next order!” The Issue: It’s possible to silence some of these alerts, but sometimes…

Background: Generally, the more letters / symbols your alphabet has, the more hassle it is to type on a keyboard. There are ways to mitigate this issue (e.g. Japanese and Chinese manage), but it’s a lot more straightforward if you can just cut down the number of symbols entirely. English, with 26 letters plus a…

Background: Hundreds of years ago, a cool looking numeric system was invented for writing numbers from 0–9999 in a single cryptic rune: https://en.wikipedia.org/wiki/Cistercian_numerals. In Figure 1, we see how two such symbols could represent a phone number. Proposal: By making use of these strange-looking numbers, ”boring“ mundane activities—like dialing a phone number—can become more exciting…

Background: When reading the news, people should ideally form opinions of the events in question based on the actual merits being reported. However, a frequent approach is: “Is this something that my nation or my political party did?
