Take your cellphone, use the camera app and turn on the flashlight, then slowly look around the room. Cameras will show up reflecting the flashlight in your phone's camera, but not to the naked eye without backlighting. So if you see a pinprick of light through your phones camera and not elsewhere, there's a camera watching - Feel free to put a piece of blutack over it, or unplug it.

Walking around in public you have no right to privacy. You, just like criminals and the police, are in a public place with no reasonable expectation of privacy from anyone around. Anyone can, and will, be able to record you, both for their safety and your own. If you don't want to be caught doing something illegal on camera, maybe don't do something illegal. And despite the prevailing paranoia around, you are not interesting enough for nefarious people/"duh gubmint" to go to the trouble of subpoenaing every possible camera within the radius of you and processing all that video to track your activities.

This speculative presentation was made at the latest in 2019. It was speculative at the time, and not an indicator of firm plans. And in the 4 years since, things change, especially considering the pandini has pushed back what little plans they already had.

I remember seeing "Hissing Sid" on Tomorrows World, reporting that domestic robots were only 10 years away. That was 1987. Or maybe "Mabel the Robot Housemaid" is more your style. Again, 10 years away, this time back in 1966.

No, but "redundant communication capabilities" means they have a backup communication system (likely cellular or similar). This is why you have redundancies.

Yes, the higher the number the better. But there comes a point where you're running into diminishing returns. The 3-2-1 system, while not perfect, is reasonably cheap and easy to implement, and gives the best "Bang for your buck". If something has happened where all 3 copies are unusable, despite being on 2 different media types and with one backup stored offsite, you have a much larger problem than data loss.

Hard-Drives and SSDs don't require power to move either, I'm not sure what your point is there. And while LTO tapes are (comparatively) cheap, the drives, libraries and storage robot systems for anytime on-line access are most definitely not. It's also part of the 3-2-1 typical backup strategy: at least 3 copies in at least 2 formats, at least 1 off-site.

They're a cloud backup company, which means they need lots of storage, but don't particularly need high-speed. They're not a CDN, or a cloud computing provider. Their data is moving at internet speeds, not LAN speeds, and any inherent slowness is taken care of by the RAIDing of the drives together. At the moment, spinning hard-drives are still at least 5x cheaper per terabyte than flash-based SSDs (Seagate Exos X16 14TB HDD Enterprise @ $20/TB vs. SAMSUNG 870 QVO-Series 4TB SSD @ $110/TB).

Electric cars and there ilk still make noise at low speeds, it's just their dinosaur-burning brethren that make a LOT more noise and thus drown them out. But even if they didn't, there's this handy device attached to ALL cars since the 1900's that will solve this problem: It's called a Horn.

The problem with Fracking isn't the drilling, it's forcing an uncompressible fluid into the hole you've drilled, sealed at high pressure, to fracture (hence "Frack") the layers of strata apart to give the methane trapped within a place to escape to.

Geothermal injects water at low pressure, and allows the resulting steam to release to generate power. The drilled hole is (typically) lined so it doesn't fracture and cause problems

Personally, I have it rebound (thanks SwiftKey) to F13, which is then used to trigger "Push to mute" in Discord/OBS/Voicemeeter. This is real handy for an anti-cough/privacy button when streaming and the like. I'm sure there are a lot of other uses, but that one means I don't have to alt-tab out of an active application/game/whatever.

Using Amazon.com for pricing (summarized by the fantastic https://diskprices.com/ ):
HDDs are currently available at $15.33 per Terabyte (https://www.amazon.com/Hitachi-HUA723030ALA640-UltraStar-7K3000-7200RPM/dp/B005QTSDDQ)
SSDs are currently available at $93.74 per Terabyte (https://www.amazon.com/ADATA-SU655-960GB-Internal-ASU655SS-960GT-C/dp/B07K1NB8XN)

That means that SSDs are currently 6.11x more expensive than HDDs. And when you're using multiple devices in RAID, especially as BackBlaze are for backup storage, speed is not essential.

This is Newsweek. Not exactly a tech-heavy publication. So rather than going into the weeds, they kept the article simple for the non technically minded.

Just because you can't "See" a player, doesn't mean they're undetectable. Footsteps and reloading sounds (for instance) need to be sent to the client to give the player an idea of where a hidden enemy might be, and that data can be hijacked and displayed in a visual manner to give X-Ray like abilities. And while this isn't what was happening in this case (In this case, they were using a second account, logged in through a VPN to hide the duplicate IP, and playing as a spectator, with the spectator data being relayed to an overlay on their playfield) it's another example of how difficult these things can be to detect.

Yup. The PC was modular. And so was the Amiga. Sidecar expansion, trapdoor expansion, and clockport expansions were all available for the A500. Or you'd buy a big box Amiga (the A1000, A1500 or A2000), which took both ISA (just like a PC) and Zorro cards, could have an x86 co-processor for running DOS or Windows.
