Compound that 'remembers' phase transitions could have uses in computer memory

Kevin McMurtrie Silver badge

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.

California to phase out internal combustion vehicles by 2035

Kevin McMurtrie Silver badge

Re: Not going to happen

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.

Heroku to delete inactive accounts, shut down free tier

Kevin McMurtrie Silver badge

Paying abusers are OK

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.

Deals are being 'inspected by higher levels of management,' says Salesforce

Python tops programming love list – but if you want a job, learn SQL

Kevin McMurtrie Silver badge

Re: Python--

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.

80,000 internet-connected cameras still vulnerable after critical patch offered

Kevin McMurtrie Silver badge

Cheap now, expensive later

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.

Lawsuit accuses Oracle of facilitating sales of 'billions' of folks' personal data

It sounds like Oracle is accused of illegally trading personal data rather than illegally gathering it directly like Google does. It's a mix of crime and laziness that I could believe Oracle is doing.

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.

Network congestion algorithms have design flaw, says MIT

Duh

Google blocks third record-breaking DDoS attack in as many months

Distraction?

My own computers have been blocking lots of SSH attacks from Google's 34.x.x.x and 35.x.x.x networks since August 16th. I'm not sure if that's from account take-over attacks hidden under the DDoS or if Google is just taking the next step to their Yahoo-like demise.

NASA selects 'full force' for probe into UFOs

Email should never disappear. That's a serious configuration error.

Mine refuses to accept delivery of spam. If any email to me vanishes, it's the sender's fault. I'm looking at you, SendGrid.

Kevin McMurtrie Silver badge
Facepalm

IT much?

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.

Tesla expands Powerwall-to-grid program to cover most of California

Re: A good start... but V2G is better...

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.

Kevin McMurtrie Silver badge

Re: $2/kwh is a lot of money

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.

Intel finally takes the hint on software optimization

Kevin McMurtrie Silver badge

Re: Wake me up when they repeal Amdah's law

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 gets the green light to flood US Gmail inboxes with political spam

Kevin McMurtrie Silver badge

What's the catch?

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.

Scientists unveil a physics-defying curved space robot

Kevin McMurtrie Silver badge

Weird setup

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..

Google's ChromeOS Flex turned my old MacBook into new frustrations

No thanks

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.

Amazon to buy Roomba maker iRobot for $1.7b

Kevin McMurtrie Silver badge

Smug Amazon

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.

Re: Eggs in one basket

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.

Pot and kettle

Taiwan's and China's networks have been a toxic mess since they came online, even if it's for different reasons. It's just political to call out all the attacks now. There are any other number of countries that could be accused of the same - Korea, Russia, and definitely the US.

Google asks workers for ideas on being 'more focused and efficient' in internal survey

Kevin McMurtrie Silver badge

∞ / ∞ = Not a Nice place to work

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.

Decentralized IPFS networks forming the 'hotbed of phishing'

Kevin McMurtrie Silver badge

Why bother with tricks?

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.

Apple-1 prototype hand-soldered by Woz up for auction, bids expected to reach $500k

Kevin McMurtrie Silver badge

Re: Open source?

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.
