Comment Re:so many gadgets have built-in batteries (Score 1) 114

According to my notes, I have here:

9v: 13
AA: 13
AAA: 17
AAAA: 1
C: 8
D: 2
coin: about 30
SLA/FLA: 5
LIFE: 4
lipo/nimh pouch and pack: 25
lipo cell: 9
nicd/nimh cells: 20
sealed plug-in charged: 16
sealed usb-charged: 27
uncommon disposable: 3

Those are not battery cells, those are devices. So for example, 16 of my AA devices use six AAs. (I have a crap-ton of NiMH AA, well over 100) and all of my C devices use at least three cells. So, sadly for me, there's a huge amount to keep an eye on. I realize I'm somewhat of an edge-case here, but that also makes me a good "how bad can it really get?" case study.

Comment so many gadgets have built-in batteries (Score 1) 114

I reviewed all the gadgets in my house that have batteries. Not just non-replaceable or rechargeable, but ALL batteries. I'm a bit tech-heavy here so I was expecting there to be a lot, but the final count still surprised me. (and I'm still finding stragglers from time to time)

The "biggest offenders" I have are flashlights. I've got a few cheap "webcam" lights, as well as several house flashlights that all use built-in lipo pouches, which I can replace, but not the average consumer. And I've had to replace my car GPS batteries several times over the years. I'd bet 98% of these are thrown away as soon as their battery gets marginal. I like to maintain and repair my stuff, and it "grinds my gears" to see these made to be thrown away.

The other thing that annoys me is that most of these gadgets have almost no "battery management". When you plug them in, they charge to full, and hold at full charge if left plugged in, which will inflate a lipo pouch in a few months at most. And many of the others will allow their battery to deep-discharge to the point of battery damage or even placing the device in an unrecoverable loop. My Garmin GPSs are terrible that way. If they get too low, they'd be bricked for most people because they always boot up when their dead battery gets a little bit of a charge in it, which isn't enough to boot the device, and then the boot process crashes, draining the battery faster than it can charge. Recovering that requires removing the battery and manually charging it, which most users can't do since the battery isn't "user" removable.

And then I have the related problem of dozens of infrequently used devices that I could easily go a year between uses on, and when I get them out their battery is dead and probably slightly deeply-discharged. And I can't leave it on charge because it'll cook off the battery by the next time I need it. Which again is really frustrating.

Then there's the "big ticket items like the exploding (pun intended?) market on rechargeable yard maintenance. Be it a hedge trimmer or a mower. Nobody knows how to take care of their batteries, they don't tell you in the manual, and few have management, so they leave them on charge over the winter and the battery is half cooked by spring. Then after another winter on charge the battery is totally cooked and they have to replace a $40-$150 battery. It's quite the scam! Along with removable batteries, built-in management needs to be legally required for batteries over a certain price. Even my quad (DJI Spark)'s batteries are smart and will self-discharge to 65% if not used for 10 days straight - so it's not difficult to do even for smaller batteries, they just refuse to do it because they want to sell you new batteries regularly instead of making the batteries last.

Comment it's not about power (Score 5, Insightful) 123

POTS lines use very little power nowadays. Decades ago they still used very little power, except when ringing. Those electromagnets hitting big bells did take some juice, but the actual power required once you lifted the receiver is very low. Modern (transistor-based, with piezo tweeters for ringing) are much more efficient, all the time.

This is about them having to continue to keep tabs on and maintain equipment that they've been maintaining for decades. This isn't about additional costs, it's about them wanting to cut costs by ditching gear that's expensive to maintain and gets far less use than it was designed for. (it's efficient at scale, and the scale has gone)

I can't say I blame them. Imagine your old house got central air a decade ago, and you still have a window air conditioner in the living room, and you'd like to get rid of it, but the city is saying you can't remove it, and have to keep it maintained and working, and pay for annual inspections.

The only reason we still see around 4% landline usage is simply inertia. Old people don't want to give it up because they don't like change or learning something new, younger people that have it don't have a reason to get rid of it and see it as a cheap "just-in-case" backup, and there's a really small percentage of people (I'd venture a guess at under a tenth of a percent) that have a good reason to keep it.

So the question is "at what point do we tell that tenth of a percent to look elsewhere?" There's tons of other good examples, how about leaded gas? or R34 freon coolant? or businesses accepting cheques? or something closer to home on the issue - pay phones on many street corners? Technology moves on, and the longer you wait to move on once the writing is on the wall, the bigger of a personal hassle it's going to be. (I see this all the time with computers, upgrade people! get rid of that ten year old doorstop! I don't care if "it still works", you need to modernize!)

so the TL;DR of my rant is "it's not about the power use, but the telco doesn't want to come right out and call you a hold-out that needs to get with the times so we can all move on." Power savings looks like something that's "good for everyone" instead of pointing fingers at the stubborn few.

I hope nobody's complaining that it got publicly disclosed because "they only had two and a half years to fix it but hadn't gotten around to it yet"

IMO, "responsible disclosure" taps out after six months. Anything that happens after that is entirely on the devs for not bothering to plug holes that they were privately notified about.

does anyone (govt etc) have back-door access to it?

It seems that lately governments are "insisting" on back-doors into user-encryption, going so far as to bar sales of products to their citizens that they can't just look at anytime they feel like it.

Yes a bit OT but I remember the one-liner contests the magazines would have. You had to not use any unnecessary spaces, single-letter variables, use any command shortening method (like "?" instead of "print") and other tricks to get as much function as possible out of the ~253 bytes of line space available. Amazing what some people could squeeze onto one line of BASIC! (games were the most popular, though graphics displays were frequently featured)

It was pretty normal for those "one-liners" to take up a third of the screen or more when LIST'ed

Back in the day most of the computer magazines had one of those. I think it was Nibble magazine that published several programs for the Apple ][.

IIRC you'd start the program in the background and it would watch what line your cursor was on and display a two digit checksum in the upper right corner of the screen that would update as you typed. Just make sure that number matched the check on the end of the line in the magazine and you were clear to hit Return to save the line.

A different magazine had a similar method, but I believe it provided line-by-line checksums after you were done entering the program, and would also generate a "program checksum" at the end that would match if all lines were correct.

I also remember several occasions where there was a printing problem in the magazine and everyone's checksum was wrong, they'd publish a correction in next month's edition and everyone would cry "THAT'S why I couldn't get it right!" (probably after receiving hundreds of letters in the mail complaining about hours of frustration trying to key it in!) This was frequently due to the magazine omitting a line of code. (all the line checksums matched, but not the total at the bottom)

ahh the good ol days of Human OCR....

Side mirrors almost always leave a large blind spot directly behind and close to the vehicle. There's a reason that when firefighters are reversing their appliances they always have at least one of the crew physically get out and watch the area behind the vehicle.

Even a rear window and rear view mirror almost always leave a significant blind spot low and close behind the vehicle, which is why reversing cameras became a thing. When they're done well, they really are significantly safer, as well as sometimes making it a lot more reliable for most people to park the vehicle in difficult spaces.

One of the modern innovations I really would like to have is full AR on my windscreen. I want unexpected hazards highlighted in real time, particularly those that are more easily detectable by non-visual sensors, like big potholes or animals obscured by vegetation near the side of a country road. I want the actual driving line I need to take to follow my planned route through complex junctions overlaid slightly on my view of the road ahead. I want light amplification for night driving, ideally combined with some other technology that can reduce the glare from oncoming headlights to prevent dazzle.

Although I only want all of this if (a) it's implemented well and (b) any additional data it uses is reliably up-to-date and (c) there's an emergency shut-off that instantly clears everything off the windscreen in case anything goes wrong.

We don't need tech to replace something that works better than the tech.

Oh, don't be silly. Next you'll be making even more absurd claims, like that car theft was already a solved problem 20 years ago thanks to immobilisers, or that having separate physical controls for essential functions that you can find and use without taking your eyes off the road for several seconds to mess around with a touchscreen is safer, or that no-one ever hacked 100,000 cars at once from 1,000 miles away back when they didn't have always-on remote connectivity and allow OTA updates to their essential control systems.
