  • Smaller process means less energy. Less energy means less heat. Less heat can mean faster operation. So without changing any of the layout or logic of the chip itself to make it more efficient, just shrinking the process alone will give you a speed boost.

    But it goes further than that. Chips are cut from a wafer. The cost to make that wafer is (for the most part) constant. So if you can only make 20 or if you can make 2000 chips from that one wafer, it ultimately costs the same. But then that means the more CPUs that can be made per wafer, the per-CPU cost drops.

    So you get a more power efficient, cooler, faster and cheaper chip when you shrink the process. The entire semiconductor industry is so dependent on this idea that it invests billions into it every year because it is so vitally important.


  • Yes, it is infuriating, but getting mad at the situation only makes things worse. It isn’t like they will change or “get better” - you (hopefully) get better from a cold or illness. You don’t exactly “get better” from old age.

    If they listen to you at all, consider that a win. If they are financially in decent condition, that’s also a massive win. If you can convince them to improve their health that has the potential to help the situation - eat better, maybe go for walks around the neighborhood.

    I am going to assume that you don’t live with them, so one thing that has helped my mother tremendously is getting her an iPad. Both parents (who are older than OP’s parents by quite a bit) are not tech savvy in the slightest bit (I can not stress enough how NOT techie they are), plus their native language is not English, so communication for them has always been a little difficult. But getting my mother an iPad and installing Facebook on it was easily the best gift ever. She is able to communicate with relatives she hasn’t seen in decades. She can video chat with people 1/2 way around the world. It really is pretty amazing, especially since before the iPad, she’s never used a computer or had an email address or anything like that. Facebook gets a lot of well-deserved hate, but set it up for them, block whatever you can block and just make the it as streamlined as possible for them to use it. The large screen size on the iPad works infinitely better than a small phone screen.







  • I’ve made a few logos. One of them I used to make a stamping die that deformed some sheet metal. Worked shockingly well.

    I’ve also made a simple phone mount and a lens for the glovebox. My ultimate plan is to make the housing for new headlights, but lack of time and wanting to scan rather than measure the sheetmetal opening has slowed me down on that project.
