With this prices it is cheaper to make fuel from coal, the break even price was about 80-90 USD/barrel. And if this continues for months this will pushes wind and solar and electrical cars making natural gas and oil much less relevant.

For Toyota a spare tyre became on optional extra in Europe even on ICE models. They charge 200-300 Euro for having it.

Latest FPV drones in Ukraine became much more resistant to electronic countermeasures. Plus other drones are used as retranslators.

FPV drones cannot have powerful GPU yet to enable truly autonomous flight. And the issue is not only weight/energy restrictions, but also cost.

One non-trivial problem with async in Rust is that it leads to code that allocates on one CPU and free memory on another. That kills a lot of optimizations that system allocators try to do with CPU local caching and harms performance badly

There is absolutely enough coal to make liquid fuel for the current civilization. But if oil/gas would not exist, then electrical cars would be on the road much earlier as burning coal to produce electricity is much more efficient then

Soviet Union built one in Crimea. It worked. And nothing special was used that could not be built 200 years ago. But it was rather inefficient and in presence of cheap coal there were no point to continue with it after the collapse of Sovie

Thermal solar can be built 200 years ago. Although coal is very useful for production of steel, it is not essential as wood can be used instead.

Casualties from Mongol invasion are very likely much less than what was given in Wikipedia. There are good arguments that in fact probability of being killed has not changed throughout the history. It just in modern times wars are less freq

Mills using water as a source of energy are known for thousands of years. If oil, natural gas or even coal would not exist, that and wind energy would be used on much bigger scale. Then a solar power station using thermal solar could be bui

One does need carbohydrates for industrial bootstrap. Germans during WWII produced liquid fuel from coal. Modern version of this process becomes competitive with oil-base fuel around 80 USD/barrel. Yes, this process is very energy inte

They use the datasenter for model training, not to serve online users. Presumably even if it will be offline for a week or even a month it will not be a total disaster as long as they have, for example, offsite tape backups.

With that setup on boot or after a long sleep one first must log in into an account with longer password. Then one logs out of that and switches to the primary account with a short password.

You can setup a separated account with a long password on MacOS and remove your user account from accounts that can unlock FileVault. Then you can change your account to use a short password. You can also change various settings regarding h

If one kilogram of stuff consumes just 100Wt, then in one month it consumes about 300 MJ. So as long as things works for a year or more energy cost to put them into orbit becomes irrelevant. To keep things in orbit ion thrusters work nicely

I have found that using Cursor to write in Rust what I previously would write as a shell or Python or jq script was rather helpful. The datasets are big and having the scripts written in the performant language to process them saves non-tri

I lived in a building in Norway that had phone lines from like 1924. As it was declared as historic it was very difficult to dig newer cables. So ISP tried to use the old cables. At best one can get 10 MBit/s with a lot of packet loss.

There are stories about bodies of Christian monks that did not decompose for a log time after the dearth. Modern take on it attributes it to the climate in caves where the body was put after the dearth. But another important part was diet.

There are a lot of places where solar panels can increase yield for specific plants by providing a shade. They also can generate electricity to run electrical pumps for targeted irrigation saving a lot of water.

There was an article that described that in UK one needs 1 megawhat-hour battery over the winter to be grid independent. Judging by current trends in few years that will be below 40K USD. While this is indeed very expensive in most of US du
