Solar panel efficiency degrades over time, eventually you need to replace the worn out panels. They end up in a landfill instead of being recycled. The panels contain toxic materials and the costs to recycle them are not worth the investment. Wind turbine blades are similarly difficult and expensive to recycle. A recycling center will go out of business if they tried it. So they keep piling up with no end in sight.

Another interesting factoid... If everyone is driving an EV the existing power grid (even one heavily using green energy) would not be up to the challenge of charging everyone's EV. Not by a long shot. We are talking orders of magnitude of additional power being required. Add in business EV use and it gets far worse. A warehouse with say 100 tractor trailers and fork lifts all EVs could not actually be permitted because the power draw would cause problems to the local grid. The amount of wattage required is mind blowing. The business would need to run their own power plant. Companies that have been doing that for decades would include Pratt & Whitney who run their plants on generators powered by jet engines on the ground. They are a defense contractor and needed to ensure they could keep running even if the grid went down. They push what electricity they don't use back to the grid. But were they to take only from the grid; the grid would be incapable of supplying that much power.

What is the solution? We need to start constructing new nuclear reactors using modern designs which are many times safer than the ones we built 50 years ago. It is impossible for these new designs to experience a core meltdown. They can be far smaller and more efficient. They can use a variety of isotope fuels including nuclear waste. You can still take the holistic approach adding in multiple forms of power including green energy. The two main fusion designs are nowhere near practical. Using either high energy plasma contained in a magnetic torus (donut) or many lasers focused on a isotope target are not practical. I believe they recently reached an ever so slight increase in efficiency above breaking even. A UK design is more promising. They fire an isotope pellet into an isotope target, producing a brief fusion reaction which heats solid lithium that melts and generates the heat to create steam. It stops seconds after each firing. So they just fire another pellet every few seconds. This design is inexpensive and can scale and can be turned off near instantly. It has almost no waste byproducts. The problem? It needs to compete against designs that have spent billions perhaps trillions of dollars and such a simple design makes them obsolete. So they have been trying to suppress this new design from reaching fruition.

It's not like some normal worker, he's an executive. They are hired with a legal contract. Don't cry for him and certainly don't take glee in his termination.. He is laughing all he way to the bank. He's worked for Apple for 22 years. He has stock options and a huge salary and one heck of a golden parachute severance package. They might even pay out the remainder of his contract. He didn't resign he was forced to resign and will still get his severance package. Plus keep all the stock he's accumulated much of it when it was very cheap. Apple just wants the bad PR to go away, half the executives likely got the Arthur movie reference and chuckled. It was truly funny.

If the man decides to retire, he's certainly got the funds to do so. Or he might take the rest of the year off and seek another job. He's a tough negotiator who has saved Apple a billion or more of the years. His job is to negotiate a deal. He once sent a certified letter via FedEx to UPS when negotiating a deal with UPS. He's negotiated with Corning for the glass used in the Apple Campus and Apple Stores.

There are newer designs that are more efficient and extremely safe where a runaway meltdown scenario is impossible. Molten Salt is one such example. More fuel options including the use of traditional reactor spent fuel. Far less waste. There's also a new breakthrough fusion design using a high speed projectile pulsed reactor. Every 30 seconds you fire another projectile which causes an instantaneous fusion reaction which heats molten lithium and you exchange the heat to water turning it to steam to spin turbines. It's extremely cheap to manufacture, incredibly safe and far better than fission reactors. It's takes much less energy to operate and avoids all the problems of laser fusion and magnetic bottle plasma fusion designs. It is the most promising fusion design to date.

Mainframes and Sun Microsystems Solaris had A/B upgrade systems for decades. It's not a new concept. Different disks / partitions / slices would be toggled as bootable. PC's had GoBack which kept a disk cache of all system changes and you could roll back in time including the OS as well as all your data. Windows copied this with System Restore in a somewhat limited fashion. Apple has Time Machine. Linux can revert back to a prior kernel release by editing the boot loader. But only for the kernel. Apple's latest macOS and Apple Silicon Macs have an immutable System volume that is protected by SIP (System Integrity Protection), read only System volume, and finally snapshot to the APFS filesystem, signed, sealed and then macOS boots from the snapshot. They invented firm-links which are in-between hard-links and soft-links to mount the User volume directories and make it look like a single disk. They recently added an "Erase all Settings and Content" option which is the same as an iPhone allowing a user to quickly factory reset a Mac. The encryption keys are tossed and the startup wizard re-runs to create the initial user. This was done mostly for security reasons. You can actually dual boot a Mac by creating a new volume within the existing APFS container and both volumes do not need to be sized, they will share the free space dynamically. This allows one to try out a beta, etc. However if APFS is upgraded there might be some issues. It would be a nice touch for Apple to add A/B functionality for the System Volume to enable rollback. But with a Time Machine or clone backup you can recover. Unfortunately, Apple decided to remove the Internet Recovery option from the new Apple Silicon (M1) Macs. If you brick your Mac you'll need a second Mac and a thunderbolt cable with Apple Configurator 2 available in the App Store. That will allow you to revive / restore your operating system. You cannot boot an Apple Silicon Mac from a flash drive installer if the internal drive is wiped. You need to boot strap it with a second Mac and Apple Configurator to restore the specialized partitions and Recovery volume as well as install the OS. Apple may or may not re-address this issue in new releases.

Sure, let's have a secure Linux A/B solution. I am all for it. For decades you did this by hand. Remember all the elaborate partition schemes for Linux? Well one reason for that was to allow one to rollback a failed upgrade. But it was also useful for re-allocating storage as you can move partitions between disks. You would have the root partition a /usr partition a /usr/local and/or /opt partition as well as the /home partition which could be on different disks. Heck with NFS you might only have the bootstrap on a workstation and mount the remaining OS files from the network and all workstations would effectively run the same OS updates and configurations that could be globally changed for all. The workstations also network booted so you could upgrade the OS for all workstations all at once from the server level then replace the workstation boot image. The workstations would network boot the new image the next morning. If something went wrong the SysAdmins would roll things back.

There is absolutely nothing wrong with a hardware manufacturer and Linux distribution company creating their own desktop shell as an option and perhaps a default. Providing you have the freedom to change to Gnome, KDE, or even eliminate a desktop environment in favor of a custom environment.

A Rust based desktop shell with accompanying file manager and desktop icons along with virtual desktops, etc. Would potentially be very reliable and fast. If they pull off the necessary attention of detail to all the little things that plague every other Desktop Linux user interface. A multi-threaded file manager that doesn't sequentially copy one file at a time, etc. It could raise the bar by creating some competition. Typical developer communities working on Gnome / KDE are not performing focus groups and evaluating real world non-skilled user feedback. Dropping into the Terminal to accomplish something is a matter of course for developers. However, an end user should never need to do that to accomplish something in the GUI.

I find Pop_OS! to be highly refined above and beyond most other Linux Desktop distributions. I would be very curious to see what they do with a rust based Desktop Shell / File Manager.

Teach the robot KungFu and let it beat the snot out of the mob of unruly youts.

Plenty of corporate applications require a server or external login account (Netflix, etc, etc, etc). Does Apple prevent new startups from doing the same?

Why not install the app for free and require the user setup an account with the vendor's website like Netflix does? Apple won't let you explain it on the iOS app to the user and you have to be careful to dance around their restrictions on directing the user to your sign up / login page.

You don't have to use the subscription API's in your App. But you do have to play by the rules however crazy they may be. Make your website easy to find and easy to sign up. Sure it's not as simple as clicking a subscribe button or in-app-purchase with Apple's walled garden App Store.

"A foot and their money are soon parted."

"There's a sucker born every minute." ...

Fact is Sebastian was taken in by greed. A common lure used by scammers. Sebastian thought he would become immensely rich but he was taken for a fool. He didn't take a step back and question what he was seeing and in the blink of an eye, his Bitcoins were gone. Ever since money has existed there have been those who trick and steal from others taking advantage of their naivety. It was the combination of greed and a countdown timer to instill a sense of urgency. Both tricks are used frequently. Always be suspicious in any scenario where it looks too good to be true and there is a sense of urgency. They also managed to make the Tweet appear legit as they used a blue checked account but altered the display name. You've really got to look at the actual @name and perhaps review the Tweet history. Their website looked legit as well which is quite easy to pull off. Fortunately, most scammers are terrible and it's all too obvious they are running a scam. But you get someone well organized with a great deal of attention to detail and you'll fool a lot more people. This is big money we are talking about but even the lame scammers are pulling hundreds of millions from the USA alone. The organized crime syndicates dabbling in these scams can acquire far greater wealth.

Except the weapons have a very short lifespan and once you use them. The jig is up, the cat is out of the bag, etc. The security exploits are fixed. You have to come up with new exploits which is far from easy.

Plausible deniability is key. You just do it and you don't brag about it. Broadcasting it ahead of time is remarkably dumb. It also invites retaliation and escalation. Information Technology is full of security holes that are constantly being discovered and fixed. Some date back decades. Nationstate Cyber warfare is all about zero-day exploits which you don't want to waste. If you are holding a royal flush of security exploits you don't use them for fear of tipping the hand of the enemy to your capabilities. You save those for when you really need them during a serious conflict.

Starting a cyberwar is very bad for all involved globally.

Can't Homebrew already compile a package when a bottle isn't available? At least mine does that with Intel binaries when the bottle download is blocked by say a corporate proxy / firewall, etc. So what if you have to recompile open source binaries, I bet most of them would work with no effort.

It's all about human error, introducing bugs and security flaws. Large code bases plus complex languages means the developers might not have their heads wrapped around all the things they need to know. Coding secure C++ is difficult and it gives developers the absolute freedom to shoot themselves in the foot. Rust is a new C++ language with robust compiler that catches most of these mistakes and it's highly opinionated forcing the developer to comply with it's demands before it produces a binary. This helps ensure proper code and will not only offer better performance but better security as well. You can still write bugs in Rust but the really dangerous scenarios are greatly reduced.

I hope to see other languages take up the concepts utilized in Rust. It would benefit everyone.

Patiently waiting for the new EPYC / Threadrippers. Could are diddly-squat about gaming. I need more cores than the gaming 5000 Ryzen provides. I want to see the replacement to the 3990 64 core and the 3970 32 core Threadrippers and if they will require new motherboards or not.

So we still had HP LaserJet II's in full operation. When parallel ports went the way of the Dodo, we bought USB to Centronics cables and those little desktop lasers would whistle and squeak and they weren't terribly fast but they kept chugging along for 30 years. They simply will not die. This was the first desktop sized laser printer. I believe we got rid of the last ones just this year prior to the pandemic because we couldn't get them to work with Win10 reliably.

I miss the days when printers have their own CPU and the drivers consisted of half a dozen files that could fit on a single floppy. Now it is quite common to see 300MB+ installers with a bunch of junk software added on. Always look for the basic drivers or even better, IT based drivers.

Lemons abound across all printer brands. Some HP models are spectacular and others are to be avoided at all costs. Same with Lexmark, Brother, Xerox, etc. HP realized their mistake, they made their LaserJets far too well and they didn't break down and therefore they weren't replaced often enough.

The trouble with Google is people do not realize that these services they provide are not the product. YOU THE USER are the product. Google is a marketing company and always has been. It is how it funds itself. By selling advertisements and collecting massive amounts of data and metadata about it's product which is YOU!
