Put the ground on the tip and the +5v on the outer ring so it makes contact last. No accidental power on a data line nor can bus-powered devices be in a "running but unable to communicate" state due to a loose cord.

I don't know, I can imagine some pretty amazing sequences of events that would be best described as "Rube Goldberg Final Destination directed by Michael Bay" but I'd be willing to bet that in reality "accelerate a person into traffic" is as bad as it'd ever get, and even that would assume the person somehow never thought to let go of the scooter. Everything else that's actually likely basically amounts to "make scooter rider fall down".

That seems more like something for Lua, or even Python, rather than Javascript. I definitely see Lua as the embedded scripting language in a lot of modern apps, particularly games, so there's something to that.

The HDCP hardware is part of hardware you already have to trust not to do things like that.

Chrome extensions have been pretty much this for years. The user's never prompted to accept the key initially, but updates don't run unless the key matches. If you want to install a non-matching update you have to uninstall the old one first.

I think that's a reasonable way to do it. The only time anyone other than the developer has to think about keys is if the developer loses control of their key.

Xbox supports a keyboard just fine in the non-game UI, but they intentionally disable keyboard usage in games because too many console FPS players are gamepad whiners who know they'll get their asses handed to them if people were allowed to use proper controls.

Console devs need to just tell those idiots to get a keyboard/mouse themselves and STFU.

High-end SSDs these days, including anything deserving of the description "enterprise grade", have supercapacitors for the specific purpose of allowing writes to complete in the event of power loss.

USB drives generally don't have something like that. I'm sure some might, but most don't.

No, definitely the first one. Apt > yum by a long shot.

Notice how he uses the words "breach of contract" in the post. You can't have a breach if there was no contract.

Either Shuttlesworth is being VERY loose with legal terminology, which would generally be a bad idea for public statements from a former CEO and still public face of the company, or there was some agreement in place.

That's just Hyundai. Even my Ford with the widely hated MyFordTouch (aka Sync 2) system doesn't have that problem, nor did my previous Kia (which shares corporate overlords with Hyundai, but strangely they don't share infotainment systems even in their platform-sharing models like Optima/Sonata.

You don't. The way Iridium handles it is having some of the satellites in orbit allocated as spares and not in active service. They have 66 active birds plus six spares. The spares run in a different orbit which circles the earth faster than the active constellation but can still easily transfer to the correct orbit, minimizing fuel needs for activating one in exchange for a longer time spent waiting for the orbits to sync up properly for the transfer.

Basically you set things up like a large "cloud" host where there's enough spare capacity that individual device failures just aren't really a priority and you can replace the failed hardware in bulk every so often rather than having to do something one-off immediately.

No, encrypting the password database with a master password that's not saved means it can no longer be read directly, significantly raising the bar for capturing passwords.

Depending on user privileges this may not be possible, and would only gather one at a time.

No shit that wouldn't have helped, as long as the drive's mounted the file is plaintext as far as the malware is concerned.

Clearly you're not capable of thinking through security yourself.

Let's say I'm shithoused and inadvertently run some kind of malware that wants to steal my FTP passwords. I realize what I've done almost immediately after and shut down to restore from backups. If they're stored unencrypted, that malware could have already sent my full stored password list to wherever. If they're encrypted with a master password, the malware gets absolutely nothing. Even if I don't catch it immediately the malware still can't get it no matter what until I actually go to use those passwords.

If you can't see how huge of a difference that is I don't know what to say.

My objection is about it taking more power to keep them clear than they could generate.

If they generate 48 watts per panel, but are drawing 150 watts to run the heating elements, they're losing 102 watts the whole time the heating elements are on.

Maybe they have figured out some way to require far less power per square foot to melt snow/ice on a flat surface than the roof heating systems I looked at for reference, but they'd have to be down below 10 watts per square foot to break even under ideal conditions. That is not much heat at all, and as others have pointed out in the sort of conditions where you'd need the heaters running the weather tends to not be anywhere close to ideal for solar so the chances you'd even get 48 watts are slim.

According to all the articles and press releases power generation is the primary purpose of these panels. They claim they'll have enough surplus to offset the energy usage of the entire town square. If they are consuming more power in an hour than they could generate in three, just to keep them able to generate power, that doesn't make a bit of sense.

Now if they were hyping this as an interactive LED sidewalk that's heated to stay clear on its own in winter, and it also happens to generate some solar power, that'd be an entirely different thing. That's not what they're doing though.

My thoughts exactly. This installation has 30 tiles over 150 square feet, so five square feet per tile, with each tile generating 48 watts total under ideal conditions. Let's be nice and round it to 10 watts per square foot.

Looking at a variety of heated driveway and heated roof systems it seems that most use somewhere between 30 and 60 watts per square foot to effectively combat snow and ice. That's 3-6 times the best-case power generation of these panels.
