  • Like someone on lobste.rs says:

    Or an unrelated point: who do you believe, this data or your lying eyes? Java and Perl are not similar in their verbosity!

    How in the world does Ruby have a lower DRYness than Java? This person’s code just does not work. And Java is almost as high as Kotlin? I’ve done conversion of millions of lines of Java to Kotlin. Just a direct conversion alone will save you 20% of your lines, and that’s without even bothering to switch to Kotlin code style, so that’s with Streams and massive if statements rather than pattern matching.

    LaTeX only has 67% uniqueness? Huh???

    This article has major problems.













  • There are lots of claims going around, but the physics just isn’t there. Battery storage density isn’t high enough currently (and doesn’t look to be close) to support large planes. It’s the same problem as with 18 wheelers. The larger the vehicle, the battery size increases superlinearly, not linearly. Because adding in battery storage increases the weight required to carry the vehicle, thus increasing the battery storage needs, thus … and so on. With liquid fuel, the weight is variable based on the passengers, and the weight drops as the flight continues, thus increasing fuel efficiency the more weight is lost.






  • The efficiency doesn’t matter (to a point of manufacturing solar cells, or wind turbines, or whatever your equipment is for your renewable energy source). If all of the gasoline is generated from the air using renewable energy, it could take 100x the energy and still be completely carbon neutral. Carbon neutrality is based on the amount of excess carbon added to the air. If no carbon is added then by definition it’s carbon neutral.

    Porsche already has a factory in Chile that is doing this exact same thing at a much larger scale.
