Anecdotally the worst leg injury during hiking I heard off was from a guy in a very expensive hiking boots. Basically he slipped and his foot stuck between two stones while the body continued to move resulting in a broken bone. If he would

Sodium batteries will have any effect only in a few years. So this is mostly the case of increased production in anticipation of stronger demand that has not realized. The latter is not necessary an indication of a less demand for batteries

Meat and dairy from modern factory farms that feed animals with grain is very different from farms from, say, 19th century, when cows was feed mostly grass without antibiotics and were spending a lot of time outside. So the reasons for safe

40% diesel efficiency is for optimal conditions, like steady cruise on a motorway. For practical driving it is less than 25%. What is also missing here is that it takes 20-30% of energy to refine diesel or gasoline plus there is oil extract

What is not considered in the article is to replace pointers to pages and patterns with handles that are tagged indexes into internal arrays. The big plus is the index tag allows to detect use after free and other memory safety bugs in wast

Single executable is useful for end-user. It is not very relevant on servers or for development. On the other hand portability and debugging experience with jars are vastly better. Just consider a developer on Mac with Apple silicon cannot

The problem with natural gas turbine is the energy cost of fuel. One looses a lot extracting it from Earth. And then there are unknown, and, as such, potentially catastrophic, consequences of pumping more and more CO2 into the atmosphere. F

That just restricts A to implement Allocator trait and will allow to pass any instance of Allocator when calling methods of MyVect. This is unsafe. What is required for safety is to state that all methods of MyVec that receives the allocato

The article assumes that storing an allocator together with a container inevitably bloats the container by 1-2 CPU words. This is not necessary so. One can require that it should be possible to get the allocator from a pointer it allocates.

by _0w8t 4y ago
A Zig-style allocator that is passed as arguments requires to introduce a dependency of the type of the container on the instance of the allocator. Perhaps it is possible to specialize for that case a generic prover, but I am sceptical that

by _0w8t 4y ago
Zig approach essentially parametrizes instances of containers on the instance of the allocator. To properly support that in the type system one needs dependent types. In theory that can be done, but the consequences for the compilation time

By definition timing benchmarks cannot be Gaussian since the time cannot be negative. For anything that has such bound on one side log-normal is a safer default choice and the usage of the normal distribution must be justified.

But then who among Ancient Greek philosophers was good at physics? They only tried to explain, that is, tell stories about how things worked. They did not try to make predictions and verify that they matched the reality.

Just based on statistics it is very easy to make such generalizations. During the civil war in Lebanon in eighties it was safer there than in modern US.

This may result in poor CPU cache access pattern. For tasks that are often human-bound like source files or UI data structures using a sorted array can be a good option.

Itanic was a flop due to AMD releasing 64bit CPU. And I still think Intel learned a lot from its failure if not from the technology but business-wise. Just stick to improving the existing architecture while keeping backward-compatibility.

Native code can use a wrong abstraction as well. Around 1996 I tested on Linux a Java app that rendered everything in Java using IFC from Netscape. The speed of its UI was on pair with a native app using Motif toolkit despite the usage of i

Erlang also has reference counters for things like strings that are immutable and can be shared between threads (processes in Erlang). Overall this is a good model. Use GC for small per green thread heaps. Then use reference counters for sh

A modern natural gas power plant has over 60% efficiency of electricity generation. 40% is for rather old ones or those used for peak, not base load. But even those are improving. Moreover, using natural gas at home for heating is not 100%

By the same reasoning factory farms that feed cows with grain, not grass, should be banned, as it very significantly alter meat nutrition.
