Asymmetry
So it takes ns to write a '1' but writing a zero means waiting many minutes for memory to fade away? That's crap for traditional storage but maybe good for analog AI computations where it's advantageous to have unused paths fade away.

Most vehicles must slowly charge until the grid is updated. I don't see this as a problem other than perception. Most cars will be parked 20+ hours a day.
National holidays will be the big loads for vehicle charging, but then there aren't many commercial loads those days either. Worst case scenario is December when there's little solar, hydro, or wind power but two travel holidays.
I think bigger problem is electrifying parking spaces. It's going to require huge quantities of miscellaneous hardware that factories aren't ready for. We also need far simpler and cheaper chargers. The gas-station style chargers don't scale - too much copper, too much power, too complex, too much to break.
I complained to Salesforce/Heroku about a prolific SMS scammer with a wide-open database of personal data. I gave them one complaint per SMS. Salesforce blocked my emails.
The customer is still there and I still get the SMS spams. If you've seen scams with 'pingmeta2' in the URL, that's them. Scan the phone number query parameter to download everything.
It's important to note that there's a scalability factor for programming languages. People start with Python because it has very little ramp-up overhead. It's great for small projects. As it grows, it hits scalability limits common to dynamically typed languages. It's harder to find implementations, references, and mismatched object fields.
This is where statically typed languages win. You may curse the build and dependency tools but refactoring is a few mouse clicks no matter how big the code has grown.
Only one camera needs to be compromised to bring down the whole system. You're thinking of filling up the storage device? No, that might trigger monitoring alarms before recording stops.
If you bought Hikvision cameras to save money, it's a good bet that the storage system is cheap too. All a compromised camera needs to do is write one large file (a few TB) to storage then delete it. All but the best NAS will become unresponsive during the delete. Within seconds, all the Hikvision cameras will crash from buffer overflow. Video from the past is lost before any monitors raise an alarm.
I'm selling a 1500 MPH supercar. Now, 1500 MPH isn't street legal but we can gang up the seats to provide the throughput of 1500 MPH into a single vehicle traveling at 30 to 60 MPH. To ensure greater access to this supervehicle, rides will use a subscription model rather than up-front payments. Rates start at $1.75 for a two hour pass or $6.50 for a full day.
It's amusing when somebody screams about Spamhaus being a corrupt shadowy net traffic overlord conspiracy because they're blocked without ANY spam being sent, but they're outsourcing e-mail to a 3rd party. Quoted Tweeter #1 is outsourcing mail to the global king of phishing, Google. Tweeter #2 is complaining about Spamhaus without being listed on Spamhaus so I'm not sure what the actual complaint is.
Spamhaus is an opt-in feature on the receiving end. It's used because people like it.
Car batteries are huge compared to home hookups. The same limitation that prevents fast charging at home means you're not loosing much if the flow is reversed for a bit. If they drain your 100 kWh battery to 80% you'd get $35 to $40 out of it, depending on your cost to recharge it.
At least for the home battery systems, you choose how much PG&E may take.
I personally don't feel like doing any favors for PG&E. I'd only participate if it was really easy and made real money. Give me a monthly participation payment. I only export power from Spring to Fall but I'm being charged a customer hookup fee like a consumer.
Residential peak rate is about $0.25/kWh and rising. This offer is good for SolarEdge and maybe some other batteries too. As I understand it, it's used for testing and emergencies only.
I didn't sign up because the invitation is indistinguishable from a phishing email. There's literally nothing official about it, no references from official sites, and nobody at PG&E or SolarEdge replied when I asked if it was real.
It doesn't have to reach the arithmetic level. Conquer-and-divide libraries are getting easier to use. Java's ForkJoin system is a complete clusterfck for I/O but it works well for maximizing multi-core efficiency with minimal coding.
I'd rank bad code and bad configuration as still being the #1 limit to performance. Those giant staffing/contractor pools have their own special coding style that performs 10x to 10000x slower than it should while being completely obfuscated to normal humans. When somebody with more security checkboxes than security knowledge touches a system you can count on it losing another 20% to 90% of its performance on top of that.
Google always had excellent inbound filters and zero outbound filters. It's an anti-competitive behavior that the Feds never caught on to. When Google says they're going to allow floods of inbound spam, I smell fresh evil. It might be a feature that lets users keep score on annoying politicians and political parties. It might be teaching AI what is and isn't successful deceit. It might be training AI how to more effectively manipulate politics.
Put them all together and Google can use perfectly legal campaign contributions rather than filtering. For the party you don't like? $20 million worth of e-mail advertising donated to their most annoying candidate. The candidate you like best? A donation of $5 million worth of e-mail advertising plus $15 million worth of social engineering and targeting. Each side received $20M so it's fair. Oh, and there's a big tax write-off too.
Less jerky: Two weights spinning at end of the arm on its axis, with the two spinning synchronized in opposite directions to cause cyclical swinging of the arm. Two weights spinning on the axis of the arm close to its pivot, opposite of each other in the same direction so that they only change the angular momentum of the arm.
This needs three servos moving at a nearly constant speed, other than phase adjustment.
Not sure if it would prove anything, but it would have less noisy data..
For all the horrible things that Google has done to break cellphone features, I'd only take steps to remove their software. Google wants a walled garden like Apple despite that being beyond their skills and against what everyone without iOS wants.
Did Flex incapacitate your internal storage? That's Google's favorite feature of Android 11 and 12.
Google's self driving search-bar cars are so far away that I don't see Google recovering investment costs. The first to profit will probably be facade companies that can sell promoted routes, kill some people, then vanish overnight. Even if Google exists long enough for self-driving cars to be common, they'll won't have a monopoly to pay their investments off.
Meanwhile, Amazon gets mobile inside houses with cameras, sensors, and centralized computing for maybe $2 billion total.
The locations are chosen by culture more than anything else. You need staff with technical education and you need a town with a reasonably cosmopolitan attitude.
Ok, I'll just say it. Some parts of America are terrifying stupid and hateful. Even the police will offer advice like, "I didn't see it - maybe you had it comin," "Boys will be boys," "Nobody died," or "Things were fine until you showed up." You tech team isn't moving into the middle of nowhere just because you promise jobs.
Google has a nearly infinite codebase being managed by a nearly infinite team of employees, all working towards accomplishing tasks that upper management considers experimental. Much of the architecture is a cloud version of old mainframe designs. Programming languages have strictly prohibited features that have them frozen to a point in the past where that was feasible. There's constant clashing between the ideals of code reuse versus depreciation and replacement. People can reject your pull requests for nonfunctional reasons.
It's amazing that they haven't imploded yet. Sisyphus would quit to spend more time with his rock.
Namecheap, Cloudflare, Amazon, Heroku, Google, OVH, BuyVM and friends will host crime gangs for months before kicking them off. Once that's done, the criminals run a script and they're back up again.
Salesforce/Heroku is a newcomer wanting a slice of the cake. There's a crime gang sending daily SMS phishing links for real estate and various gift cards. The click-through tracker on Heroku is trivially exploitable to view all customer data by querying phone numbers. When I reported the spams and vulnerability, Salesforce responded by blocking me from their abuse contact. Classy.
The Apple II series was horrible to code for, but remember that every single logic gate between chips consumed well over 1 square centimeter of PCB space (DIP chip, traces, caps). Somewhere the Internet has articles calculating the cost and space saved by each hack and they add up to a show-stopper amount.
Remember all those chips in the Apple ][ floppy disk and its controller? All of that was address selectors, a 256 byte ROM of 6502 driver, a 256 byte ROM of state machine, and a one byte shift register. Head positioning, sector positioning, and the actual bits on the r/w head were all done by the main CPU. "D5 AA 96"
The same goes for the video. An analog hack from RAM to NTSC video was brilliant, cheap, and tiny.
Woz's mistake was too much emotional attachment to his past work. The chips got better but he enjoyed the tricks of making old stuff work better than it should.

Google aggressively monitors everything you do until you're trying to report criminal uses of GCP, then it's all bots and forms and can't process your complaint.
The amount of Google IP address space in various blocklists would alarm anyone out shopping for hosting. Google is probably single handedly responsible for all the blocklists adding IPv6 support.
