The point is that there is no need to tweak GR. For example, [1] shows how properly accounting for GR and using rather detailed data about Milky Way allows to explain the rotational curves. But GR is complex enough to allow very differen

We cannot simulate evolution of galaxies using equations of General Relativity. So at best the simulations are done using Newton mechanics with minimal corrections like accounting for finite speed of light. And often it is not even done us

VLAs are unsafe in the worst kind of way as it is not possible to query when it is safe to use them. alloca() at least in theory can return null stack overflow, but there is no such provision with VLA.

With Python one never knows when a particular feature code depends on will be removed. With PHP code written 15 years ago still works.

The laptop has 32 GB and the amount of RAM is not a limit here. With sufficiently fast SSD the storage is not a limiting factor either. Even RAM speed is not a big factor, it is still single thread performance that affects compilation spee

My favorite hypothesis is that it is big refrigerators at home and perhaps widespread use of preservatives that made people fat as it provided uninterrupted access to high calorie food like meat, cookies etc.

I tried the potato diet. I consider myself a lean guy, but I wanted to try it for a month before recommending it to my overweight relatives. I stopped after two weeks mostly because the stomach became rather bloated. There was no weight cha

The answer for the war is coal and this is exactly what Germany is doing. It is simpler and cheaper to run the existing coal plants at the full capacity or even increase it than try to maintain the nuclear plants long past the original desi

If water tank holds water above 70C, it’s safety requirements make it significantly more expensive. Plus water close to the boiling temperature is rather corrosive. So I cannot rule out that even for small scale sand setup will be cheaper.

It is hard to expect a different answer from a person who works for a company heavily invested into hybrid cars. What he does not mention and what the war in Ukraine has shown again is that dependence on foreign oil is just bad. Any engine

With trucks etc. there are still independent companies that can fix those and transitioning to a new provider is straightforward. With IT in cloud there is a strong vendor lock-in.

String in Rust is very similar to std::string in C++, while str is std::string_view except it is safe to use. StringBuffer in Java is not like String in Rust. In particular, one cannot pass StringBuffer in Java to a function taking String,

If one wants a blog with self-hosted comments, then there not so many options and those that exist are not particularly simple. For example, standalone Wordpress can do that, but setting it up and running with all relevant plugins requires

Indeed. The author just wrote yelling. Given the Russian culture I suspect he was yelling in chats about the situation, not blaming a particular person or team. Something like “Why the hell have we stuck?” perhaps even with f-words. Boss ex

In Norway until recently the electricity was cheap. So many apartments and even houses in suburbs use resistive heating as installing heat pumps was not profitable. But then in winter one can just mine crypto coins on GPU for free to heat t

I have done multiple times both refactoring of untyping JS and JS fully typed with Flow. With the latter after the Flow compiler stopped complaining one can expect things to work. With the former despite extensive tests sometimes it took we

For me the biggest advantage of static typing is that it allows to safely refactor code. Without it even with extensive unit test coverage refactoring often is just not an option.

The gasoline prices in US have little to do with price of oil. In 2008 oil was 140 USD while gasoline was much cheaper. The real problem is underutilization of refineries . Some of them reduced output during Covid and was not able to restor

Another important difference from the actor model is that the library uses a future interface with blocking wait to get the results. With actors there is no wait as the results are posted to the message queue of the caller. But waiting make

Chromium uses actor model extensively. Yet in Safari Apple moves into the direction of multiple fine-grain locks for performance reasons I presume. So it unclear which model will dominate the industry. Locks allow for better performance, bu

When Spectre came it turned out that it was very straightforward to implement the relevant attacks in JS. A script can use workers with shared memory access to monitor execution and get a timer with less than 100ns resolution. As the result
