Great idea, I would use something like this. Would be helpful to add tags/categories with grade level/difficulty if students want to use this for studying at their level.


categories for all problems are already available. is that not what you are looking for?

difficulty of problems will be out soon. though, not in a way where users will be able to assign the difficulty on their own.

thank you for the feedback!


Very clever. I would love to re-create this, we have the same issue with our cat.


I like the reviews at https://www.notebookcheck.net/ because they do measure fan noise.


The fan noise and laptop hot zones are two of the reasons I always check that site. Many laptops will serve as an adequate substitute for long term birth control if you actually use it on your lap.


Or a replacement for room heater. Proud owner of HP Pavilion DV5-1106AX which got me through winters of 2008-12 when I was broke.


Could be elaborated but this is 1000x better than nothing. The reader can look up what's unusual with enough hints from this comment.


Fascinating. Would love to see a "digital energy twin" product for residential properties.


Would love to hear what you're thinking! We've prioritized commercial office as it's great bang-for-buck for our business, but we'd love to expand to other verticals in the future.


Essentially, provide a way to build a digital "twin" version of my house, and get advice about improving heating/cooling efficiency.


This is my understanding too. Evolution didn't work of a master plan with clear divisions between systems..just whatever happened to work at the time.


I will still enjoy programming at 50 and will still want to it for money. But will the ageism in this industry permit that to happen? It feels like the tech culture must change to accept that there are good programmers who aren't in their 20s.


This might be the most insightful comment I've read on HN. I think this is the point people either miss or don't bother to address when claiming that they can just search for "arcane" facts instead of memorizing them.


Maybe people who get around to publishing articles in the WSJ aren't really procrastinators.


Yeah, the universality of certain experiences can tempt people to think they're afflicted with something when they just have a normal human allotment of it. Things like procrastination and anxiety may not be (or may be) distributed according to a perfect bell curve, but they are distributed on a continuous distribution. Advice from one part of the continuum isn't necessarily helpful on to people on other parts.

The most helpful and self-aware non-advice I ever got was in Little League. I asked an older kid how to remain calm when batting in a crucial situation. He said, "Just think of all the home runs you've hit, and how good people think you are. They don't think that for nothing. Think of how nervous the pitcher must be to be pitching to you. If he's scared, why should you be?" He was a wise-ass, but he had a point. Why should I expect him to have answers that were applicable to my (very different) situation?


Interesting. Was it the pairing per se or the people you were paired up with that didn't work for you?
