Re:Pimping My Casio: Part Deux on Saturday July 19, 2025 @10:43PM (#44621524)
I may have gotten a dud, but the sensor watch pro board Unused had a _really_ bad crystal oscillator. Like, slow by over 30 seconds a day. There is the oscillator fine tune complication but the oscillator I had was way beyond the max adjustment range (32k ppm). Maybe it was just luck of the draw and I should give it another shot but having a clock that needed to be adjusted every few days was unusable.
I really like those graphics, does anyone know the tool was used to create them?
Re:Tesla seeks to guard crash data from public disclosure on Thursday June 05, 2025 @05:44PM (#44196084)
Question to anyone, how does autonomy align with Tesla's goal to accelerate the advent of sustainable transport? How are autonomous vehicles more "sustainable"?

As long as processing one event does not affect any of the other events in the batch. E.g. events are file IO, and processing one event causes another event's descriptor to get closed before that event can be processed.

EV charging also uses HomePlug. When Ethernet needed to be added to an existing signal line on the EV connector, HomePlug was chosen as the way to do it. Every EV consequentially will need a HomePlug modem to communicate to a charger, so, the world will have HomePlug around for quite some time.
Re:My favourite animation trick: exponential smoothing on Friday March 08, 2024 @11:27AM (#39642665)
This is just proportional control. https://en.wikipedia.org/wiki/Proportional_control
You could either 1. itemize the charging bill on their monthly rent, if that parking spot is reserved for one tenant. Really should be no difference from the rest of their electricity use. 2. Charge a flat fee on their rent, and then give them charging for free between off-peak hours. Some utilities offer very cheap off peak rates for EV charging, 3. integrate a credit card reader or bill acceptor for cash payment. Option 3 seems hard if you are trying to cost optimize the charger hardware.

I am bearish on universal PnC being practical to implement. Every EV manufacturer has to make agreements with every EVSE operator to use the same root CAs and same billing system. If you think of an EVSE like a vending machine, there really is no interoperability precedent for this kind of payment. Tesla is special case because they operate both the cars and charging network. But if Pepsi owned and operated all of their vending machines, we probably would have seen the same walled garden.

Sounds like we need a (inverse) finfluencer index to prevent overexposure to Cramer.

"Managers will be judged", meaning if an employee does not want to relocate, it is their direct manager's problem. Sounds like a great way to ruin a working dev-boss relationship.

Now that's what I'm talking about. Very cool, thank you.
Re:AMD Announces 7950X3D, 7900X3D Upto 128MB L3 Cache on Thursday January 05, 2023 @10:58AM (#34261608)
I'm hoping someday there will be an embedded Linux processor with this much cache. 128MB on-die SRAM means the PCB would no longer need separate DRAM. The complexity of the board routing would also go down. That much RAM ought to be enough for a lot of embedded applications.

Is there a way to use Google Pay with LineageOS? I remember having an unlocked bootloader causing issues with that.

A lot of ICE cars won't even start at 40 below. Those cases should count as zero mile range
Re:Ask HN: What's your proudest hack? on Tuesday December 13, 2022 @01:08AM (#33965409)
A few jobs ago I was working on printer firmware. There was some bug where after so many pages were printed the colors would start to band. Anyways, the fix ended up changing a == to a <=. I looked up an ascii table and it was literally a 1-bit change. I like to brag about that one on occasion but it also put things into perspective how the difference between something working or not can literally come down to a single bit.
Re:Highway EV charging will soon need a ton of power on Sunday December 11, 2022 @10:44AM (#33944096)
I'm gonna lean into newtons third law here. When you pass a magnet through a coil the coil also pushes back on the magnet. So magnets in the ground would essentially be brakes and not a source of "free energy" for the car. That's basically what regen braking is anyways.
Re:Ask HN: Where’s the best place to be in tech? on Tuesday November 15, 2022 @05:01AM (#33607265)
This has been my idea for starting a business too. Glad to hear there's a way to make a living out of it. It always seemed to me that the used video game market was tough to get into; lots of competition, easy to enter, have to deal with theft and other costs of maintaining physical (and in some case decaying) product. I've seen enough stores go out of business to scare me away from quitting my day job for it.

Even more impressive then.
I guess that assumes that the moon's starting point was the surface of the Earth and then started floating upward very slowly to where it is now.
