This reminds me of something about 5-6 years ago.
Apparently, you claim that Python broke compatibility thrice between 2012 and 2015, including 'print'. Could you be more specific? The great incompatibility (including new print syntax) that people complain about was with Python 3.0, which came out in 2008.
A link would have been helpful. I can't find anything like that by searching for "stockfish" on chessbase.com, via google.
A better door lock is cheap. More secure software is expensive.
A billion better door locks cost more than a billion copies of more secure software. I agree with the rest of your post, though.
Also; real hikers prepare their route before going on a hike.
Watch out, you're about to make a No true Scotsman argument.
A dishwasher is only more economical with water and energy for things like plates, cups, and utensils. Compared to most people's style of washing up; you can beat the 20 liters of a dishwasher by hand, but it's not easy.
It's not so clear-cut for cooking pots and pans and big items like serving bowls because you can't fit those efficiently and especially cooking pots/pans need a program that runs hotter and uses more water.
Horizontal drawers already solve the problem of cold air dropping out of the freezer or fridge when you open the door. My freezer compartment actually has such drawers (EU market). From browsing Best Buy, it seems that upright freezers in the US usually have shelves. That's a stupid design indeed.
As for upright fridges; I. guess the energy benefit is not that big. A HE fridge needs 15 W to counter the heat leaks through the walls. With a CoP of 5, that's 5 MJ of heat power day. Opening the door (150 L air) represents 3 kJ of heat. Cooling down 1 kg of room-temperature food costs 70 kJ. However, for a freezer, the CoP is lower, the temperature difference is larger, and you have ice deposits on the heat exchanger.
That provider is OBVIOUSLY notsometing the content. It has to come from somewhere.
Netflix actually has content servers located at the ISP's datacenters. The ISP only pays for the electricity and saves a lot of upstream bandwidth.
I had to explain to her that, through trial and error, I could assure her that it would take less time to get down to my setpoint than the amount of time the AC would run while I wasn't home. I think a lot of people have a false perception of that.
It isn't about the time the AC runs, but about the cumulative energy use: time times power. The power draw of a heat pump is in a complicated way dependent on the temperature difference and air flow rate. Your AC will run at maximum power and - possibly - lower* CoP during a short time, while your mom's AC runs for a long time at a lower power draw. It's likely thst your strategy uses less energy, but you can't know that for sure without actually measuring the power consumption.
* The CoP is thermodynamically higher at a smaller temperature difference (hot indoors), but typically the CoP goes down when the heat pump is moving a lot of heat.
The second thing they need to get over is tying infotainment and critical systems to the same comms bus. These should be totally separate. If infotainment needs drivetrain info, the communication should be one way only - drivetrain ---> infotainment. No handshaking and no acks - it shouldn't be possible for infotainment to even query the drivetrain or critical safety systems, nor anything that affects their operation.
That might be a lot harder in practice than in theory. How do you implement that? Nonstop broadcasting all data that might be needed, just in case the user pushes the button "status report"? Which system can talk to the door locks? They must be unlocked with low latency in case of a crash. How do you install firmware updates? How do you handle the video feed for speed limits, collision avoidance, lane assist? The user may need to change settings related to those or may wish to review them as dashcam footage, but they're obviously also connected to safety-critical systems.
We're still trying to play catch-up after the Ever Given container ship caused a huge backlog when it got stuck and blocked the Suez Canal.
Apart from that, the Ever Given and the 20,000 containers on it are still in Egypt, only to be released when the damages are settled. Must really suck if your small company has a one of a kind shipment of some custom made product sitting on that ship.
This isn't about Linus's opinion on vaccines, it's about his very efficient smackdown of an idiot trying to pollute an important technical mailing list with political bullshit. The story here is that the Linux kernel list is for discussing the Linux kernel.
The thread was actually about organizing the 2021 Linux kernel summit event, given restrictions on travel and large events that vary between US states. From that topic, it is a very small step to politics.
CPUs do have issues with cosmic rays, but shielding can prevent that (at some cost).
Cosmic rays were able to pass through the atmosphere, which has an areal density of 1 kg/cm2, roughly equivalent to a 10 m water column. I don't think that adding significant shielding is trivial, unless you think of moving data centers underground.
About TFA, the way you get a 8-minute charge time for a cell phone is you install a 12,000mAh battery, but you tell everyone it's a 8000mAh battery. Then when the phone is "fully charged" it's actually only 70% charged. That's the typical way to get a "100% charge" in an 8-minute charge time while still having relatively cool charging, good cycle life, etc. this is legitimate engineering practice and the "100%" level is always a de-rates value based on the design intent and end use.
That would be good engineering, but I wouldn't be too sure about it. My OnePlus phone has a proprietary 65 W charging system, which charges at a 3C rate up to 40% and then tapers down to 1.3C (50%-90+%), switching to constant voltage when it reaches 4.45 V. The 100% level is when the charge current drops to 0.2C or so at 4.45 V but it will keep charging until the current is near-zero). The numbers suggest that you'd need to de-rate this type of Li-Po cells by at least a factor 2.5 to work with ultrahigh charge currents; that is, assuming that OnePlus didn't compromise badly on battery wear. Would Xiaomi really put in a 10 Ah battery de-rated to 4 Ah? That would be a bulky phone.
Apparently the OnePlus battery is spec'ed for 4.45 V; pictures of the original battery show 8.9 V as maximum charge voltage (two cells in series). But 4.45 V is really high. Not so long ago, 4.2 V was considered the maximum voltage for Li-Po batteries. And I hope that the balancing circuit works well so that it's not one cell being charged at 4.5 V and the other at 4.4 V, because that would definitely kill the battery quickly.
If I charge this phone from a standard USB-PD laptop power supply, it charges initially at 1.4C (-50%) tapering down to 0.45C (70%-90+%) and finishing with 4.45 V constant voltage. For some reason, the charge current is 0.45C even though the electronics are capable of 1.4C. Is it to make the proprietary charger look better? Or is it to offer the user a way to extend the battery life?
I for one don't use the OEM charger anymore. USB-PD and unplugging the cable at 80%. From my previous phone I know that charging to 100% and trying to keep it topped up during the day will wear out the battery within a year.
CO2 freezing temperature is -79 C for pure CO2 at atmospheric pressure. Just like water doesn't spontaneously condense out of ambient air below 100 C, that wouldn't happen with CO2 either.
You'd need to compress air (0.04% CO2) a factor 2500 for the CO2 to freeze at -79 C or lower the temperature down to -150 C, both of which cost a lot of energy.
In Europe, they use steel cans which can be sorted magnetically. In the US, they're aluminum which has to be separated manually.
Aluminum pop cans are pretty common in Europe, at least the parts of Europe that I know of. Aluminum can be separated from nonmetals and steel very easily, using eddy current separators. For example here: https://youtu.be/2yRWCanU0kM at 1:30.
