In the thermal runaway video, you have steel bars holding the battery down. Is there risk of the battery casing blowing apart without that steel holding it down?

Lots of my bike tools I have will take over a decade to get my money back on my stuff alone. But I get to do something I mostly enjoy. I can also help out friends/acquaintances when they need it. The same goes for this.
- Bikes will last decades with good maintenance. An iPhone wont, even if the device hardware was somewhat kept alive most standard software functionalities will be lost.
- Bikes don't mandate fancy tools for regular maintenance. Regular people won't need your super pricey tools to replace brakes or tires. You can use them if you want to, but that's your hobby, not what the maker mandates.
You can enjoy nice tools, but that's orthogonal to the issue here IMHO.
> Bikes don't mandate fancy tools for regular maintenance.
Phone batteries need replacing every few years. The kind of maintenance that a bike used daily will need on that schedule is absolutely stuff that requires fancy tools.
Current iPhone batteries are rated 1000 cycles. That's many years if you mostly leave your phone in standby, that will be less than a year before it significantly degrades if you're using it daily and not just for web/SNS browsing.
That's my home's experience, if you listen to The Vergecast that's the hosts' experiences as well.

That's... a bit surprising. Maybe one or two I could see, like a truing stand or some one-off equally proprietary thing for one brand of part, but what else?
Edit: nvm, there seems to be plenty of Park Tools brand niche reamers and so on that are many hundreds of dollars. I would think they'd remain viable for much longer than a battery replacement press though, since you'd adapt it to a particular bike's repair needs with different bits.
Sorry to hear your experience hasn’t been great. I’ve been using it from NZ for the last six months and haven’t noticed any speed differences. Just did trips to Canada and the US recently and I didn’t notice any difference in performance.
With the exception of losing weight (already a 22 BMI) I tried pretty all of this to no avail. Turns out I had a deviated septum and surgery fixed the problem. As a bonus, I can easily breathe through my nose now.
Septoplasty and tubinate reduction surgery was one of the best choices of my life. Lifelong allergy sufferer, being able to truly breathe was profound.
I've read horror stories about that. Apparently a lot of the problems could be solved by teaching kids how to breathe (no mouth breathing), having a proper diet (chewing), &c. of course once you're fucked you're fucked and you have to go to these extremes to get your life back. It's like our lifestyle is slowly evolving us out of this planet
I have a deviated septum, but the doctors in the US doesn't think its medically necessary to do Septoplasty and I also have a sleep apnea, come to think I should get this done.
Not sure on the accuracy or if it applies to you, but prior to getting the septoplasty my ENT did mention it might not make a big difference if overweight or obese and so often doesn’t recommend it in those cases.
For comparison, I used some of those nasal strips before surgery and the post-surgery were very comparable, so that might be an inexpensive option to try? I also recall someone mentioning some sort of nose plug thing from Amazon you could get that does the same thing.
When I first learned two's complement I sort of accepted it as something to memorise for a test and didn't really understand (or care) why it worked.
What really made it click for me was thinking of it as modular arithmetic. If you consider 8-bit integers, they range from 0-255 and you're actually working modulo 256. So you can think of 0-127 as your non-negative numbers. The numbers from 128-255 behave as negatives modulo 256 (e.g. -1 mod 256 = 255).
I’m curious why you think mathematics doesn’t need to be covered here. Immediately after covering the maths background, the author jumps into elliptic curves and I can’t think of how to understand that without understanding a little bit finite fields and groups. The maths covered seems essential for almost the entire last third of the book.
