Probably not international in context. Most IR receivers go behind a special semi-transparent plastic. That's also the cheapest place to put an LED. I think there are films you can get to block non IR light. Some tvs also have a connection to add an external ir receiver.
I'm a guy who has disassembled and reverse engineered a standard Jazzy power chair, and what I noticed was the attention to detail regarding failures. The chair is thoroughly designed to shut down at the slightest bit of trouble. There's some redundancy in things like the controller, where it used redundant hall effect sensors that were identical to the others, but ran in an inverted power profile, to detect any weirdness in the sensor outputs.
I ended up adding a long range remote control to it. A remote control power chair is fun to drive around. People do get a little concerned when they see a chair rolling around without a driver
My mum recently had a curbside crash while she was riding an e-bike. This resulted in her breaking bones in both her hands, which resulted in a surgery in her left hand and various problems (tcl fracture related) with her right hand.
This makes me actually appreciate reliability in e-vehicles motor cutoffs etc.
I keep thinking if this could have been avoided with a better quality e-bike or if actually it would be even worst with a cheaper one.
Which makes one think, how often a wheelchair with cheap e-scooter parts would crash people into staris, cars etc
I know public use devices have their own problems with reliability, but I did almost cause a traffic accident a couple times over the years. Every time, the scooter's accelerator lever got "sticky" due to repetitive (mis)use, and would sometimes not go all the way to 0 when released. Stuck at ~10%, the scooter would brake normally and remain at halt under my weight, but the moment I stepped off it, it would suddenly launch itself at the cross traffic.
It's these little things that get you. The scooters all have some kind of debounce logic, disabling the accelerator until you're moving sufficiently fast - but the logic doesn't kick in when you stop without releasing the lever. A little bit of redundancy would've helped here.
A friend has an e-unicycle (I think the category devices has some other name as well..) and he wanted to try out how it behaves in a track.
He sort of knew, but didn't expect it, that when the roll of the device exceeds a certain threshold, the device will shutdown. Even if you're on a curve going with some speed. Broke his wrist. Since then he's also wearing wrist protectors that keep the hand straight.
Actually it was a bit unexpected that it would have known to do that; it must have used its complete IMU data to even know it was rolled, as plain accelerometer would have been pointing "down" as usual.
I'm an embedded software engineer with past experience developing robotics and motor control drivers.
Those e-unicycles terrify me. No way I'd trust my life to one. Once you're at speed, every failure mode results in instant passenger ejection. I see people flying through traffic on those things - they're just one sensor glitch or integer overflow away from serious injury.
> Actually it was a bit unexpected that it would have known to do that; it must have used its complete IMU data to even know it was rolled, as plain accelerometer would have been pointing "down" as usual.
That actually feels like overengineering based on well-intentioned, but wrong specs. You probably want to just use sideways acceleration for "falling over" detection, instead of roll.
The safety with ebikes does vary a bit although I'm not sure it's down to price. My one is quite a cheap one but has quite a lot of safety features - will only go if you pedal it, motor cut if you touch the breaks, 14 mph speed limiter etc. But I guess you can come off any two wheeled vehicle.
I get that a lot with default terminal colors - on black background, dark blue and dark red look shifted in opposite directions relative to baseline (white/light colors); when both colors are used in close proximity, it gives me a strong and quite distracting 3D effect.
I always thought this is specific to that color combination (red and blue on black) and LCDs, thus is perceivable by anyone, and could be used to create intentional 3D effects; I never considered glasses may be a factor too.
Are you seriously arguing that Microsoft is intentionally trying to "extinguish" it's own IP? I realize that "Embrace, extend, extinguish" is a hopelessly tired and outdated meme, but trying to freshen it up by arguing they've now reached a level where they are intentionally trying to kill their OWN products as part of some grand and 30-year-in-the-past EEE "plan" is simply absurd.
I don't follow Minecraft or this issue closely, this is pure speculation, but MS could be trying to extinguish self hosted servers and would prefer all players playing on official Mincraft servers.
Yes, self-hosted servers, hypixel, etc, and java edition are clearly the target.
It was bad enough having to pay twice for the same game (java edition, then bedrock edition, as some of their friends could only play the microsoft edition on their Nintendo Switches, etc).
But if microsoft cause the 3rd party ecosystem of servers and mods to close down forcing everyone onto microsoft servers, I will ban my kids from playing at all. Quite sad, they and their friends have grown up with minecraft, it's almost the lego of our times, with a dose of capture-the-flag, though my kids also have lego and play skirmish irl.
I support your decision to ban it in your household under that circumstance. If Microsoft gets to carpet-ban us and our kids from the game, we can carpet-ban them from us and our kids. Take your responsibility as a parent seriously, spend time and engage and take care of your kids, don't depend on big centralized computer systems to keep your children safe. Teach them why it's important, and they'll grow up to value individual freedoms.
They are perfectly happy playing in the current open ecosystem, why should they be forced to change?
I'm maybe being a bit dramatic by saying I'll ban them, but they will certainly be given a lesson on taking a stand, and if necessary making sacrifices, to defend freedoms and not give in to coercion.
It's not at all 'microsoft bad', except in this case, it seems they are.
Precisely, it's a teaching opportunity. My parents denied me certain things, and while I "hated" them for it sometimes, I have grown to understand why. It did have the very real cost of making socializing more difficult, and yet precisely that prepared me for this kind of sacrifice. Long term, I'm grateful for that, they were real, actual parents.
If Microsoft wanted to extinguish self-hosted servers, all they would have to do is stop releasing the server jars and/or turn off authentication for non-Microsoft servers. They wouldn't spend so much time and energy pushing a controversial chat monitoring feature.
Java doesn't make them money outside of an initial purchase. Subscriptions to realms do. So, yes, EEE to an offering that was free to play after initial purchase.
This doesn't make sense. They bought Minecraft 8 years ago, and it's grown by an order of magnitude since then. It's a huge cash cow for them. In what way is that consistent with the "embrace, extend, extinguish" strategy from 26 years ago, when they had an entirely different leadership team and business model? How is this not just a dumb move on their part, and actually part of some master plan to ... what... lose money?
Nah, this take it just conflating unrelated historical talking points about Microsoft without regard to how specific things actually happen. A better question is: what incentive does Microsoft have to alienate its playerbase this way?
The answer is much more mundane corporate decision making dynamics: an online game played by children is ripe for abuse by predators, and someone representing PR or Legal won the argument that this functionality is necessary. It would have been great if someone representing Community, UX or Engineering could have won the argument, but sadly those arguments are harder to make in today's political climate, so that's where they landed.
> A better question is: what incentive does Microsoft have to alienate its playerbase this way?
It does continue to condition the peasant-consumer class, especially the young ones, that the products they pay for can be taken from them on the whims of their corporate overlords. That they should expect to censor themselves and each other to appease their betters. Xbox users learned this already (https://www.ign.com/articles/2018/03/27/microsoft-can-now-ba...), now minecraft users will lean their lesson, and tomorrow it will be Windows users (and therefore 80% of the worlds computer users) who will learn to obey Microsoft's will. Software is a Service and no matter what you paid or how long you've used it, that Service is still only a privilege. Displease your masters and that privilege can and will be taken from you.
Okay, that is an exaggeration, but not nearly as much of one as I'd like.
I'm not endorsing the decision, I'm just saying this is how things happen in the corporate world. It has nothing to do with embrace/extend strategy, and it's not a product of Microsoft acquisition per se, it's just the way corporate decisions are made.
Keep in mind the people involved are no less smart than you or me, but they are responsible for single concerns, and the winning concern will be the one with the best narrative and metrics to back it up, because the tie-breaking executive will not have bandwidth to understand either side deeply. If we want to effect change, we first must understand this dynamic.
Anecdotal, the last "unsmart" TV I found was hobbled to the point of not even having a power indicator LED.
It wasn't used much until putting a "good smart" device behind it...in this case a Roku.
Orwellian prophecy in real life, the Roku sends data back to the company about anything you watch using that device.
The only difference between this setup and a "plus good smart" TV is that anything else displayed on the TV(pc, pirated movies, photos, playstation/xbox/nintendo consoles, etc) will be fingerprinted and sent back to the company analytical department.
My opinion is it is none of their business.
This is all acceptable because manipulation via marketing/advertising is considered a necessary evil, and, the device is easy to use.
Popular or not, there is a lot of merit to that view. After all a lot of the emissions are driven by manufacturing of goods for export to the West, thus it makes sense for us to take some responsability for them
Cover the light, I thought!
...the annoying light is adjacent to the IR receiver.
Cover the light, no remote.
Is this intentional?
