For performance you want to reduce context switches between processes including the kernel. With kernel bypass you do everything in one process in the user space, but you are also losing out on features like sharing hardware resources betwe

It's not a hack. Virtual address spaces and process isolation were built exactly for misbehaving code.

A common thing seems to be that the reasoning behind the rule is missing. I have personally seen single return recommended for C# code, when the original reasoning for it is manual memory management.

It’s weird to me to reduce safety to numbers of deaths. If a kitchen machine chops of a lot of fingers of users I wouldn’t call it safe. I think the risk that you have to evade everyone in a circle of several kilometers has to be taken into

Money supply increases don’t necessarily lead to inflation. They only do when there’s more consumer spending on products. In the recent low interest rate period, that didn’t really happen. Money instead went into an asset price bubble. What

The key words in your comment are 3 cars (plural) and 15 years. 15 years is a typical lifespan for one car. And the thing most commonly limiting that lifetime is the engine breaking, totaling the car. My guess is that this will be happening

There seems to be some movement in putting PV on the roof of cars. With that you can get a significant part of the needed electricity of everyday driving (average is between 30-50km, if you remove long distance trips you end up with much lo

I guess it’s more that what is developed is lead by product people and those don’t know how to plan for performance issues and instead inadvertently push for more features in a shorter time.

The question is wether you really need to be literate. As a software developer I cannot write correct assembler code ( with aligning rules, red zone and what not), but at least I can read it. I would guess most programmers cannot do even th

Energy is just one factor, that played a huge role because we come from a world where lack of energy was limiting a lot of things. The easiest counterpoint is energy efficiency. Often it reduces energy use while even increasing wealth. The

Just wait a few years when photovoltaic roofs will become the standard. Cars seem to get driven 10000km/year on average in Spain, which is around 27km/day which is doable with solar car roofs. I guess especially for people living

Making houses less draughty is just one point (convective heat transfer) another point is making walls conduct heat less to reduce conductive heat transfer. Uninsulated houses often has higher risk to mold because of cold walls. Warmer air

Heating with air is less efficient in transporting heat with water. So you either need to move more air or heat it up to a higher temperature. The first one is obvious why it’s a bad idea, the second is a bad idea as at a certain point the
