Even though our computers are now better than 15 years ago, they still malfunction 11%–20% of the time, a new study from the University of Copenhagen and Roskilde University concludes. The researchers behind the study therefore find that there are major gains to be achieved for society by rethinking the systems and involving users more in their development.
At least 10 percent of my time sitting in a classroom in college was waiting for the prof to get the projector to work with their laptop.
So far I am lucky enough to have not had any classes that have had the issue of a professor not being able to get their projector or computer to work.
Closest I had was the Linux VMs we were using for a Linux fundamentals class were having troubles because someone gave them too much resources by accident (I think it was memory but I don’t fully remember), causing them to sometimes just stop working because there wasn’t enough for every VM. Somehow persisted pretty much the whole quarter before being figured out.
