Look at recent Microsoft releases: we don't fix old features, but accrete new ones. New features help much more at review time than improvements to old ones. (That's literally the explanation for PowerShell. Many of us wanted to improve cmd.exe, but couldn't.)

In this article, author talks about how to improve the accuracy of software development effort estimations. He suggests to use relevant historical data improve estimation accuracy and to avoid early estimates based on incomplete information. He also discusses how to measure and predict productivity in software projects.

the translated strings are stored on the heap, where the garbage collector must scan over the objects on every run (at least in the case of Ruby MRI). For a mature process with all the translations loaded, this is almost 1 million objects! Second, each process has its own copy of the strings.

Reasoning is important. This course will teach you how to do it well. You will learn how to understand and assess arguments by other people and how to construct good arguments of your own about whatever matters to you.

Matz is experimenting with three concepts that may or may not be included in Ruby 3.0. 1. Man-machine collaboration through a static analyzer (e.g. rubocop or ruby-lint) that uses soft typing (i.e. inferred typing) to determine if a program will crash or not. 2. Performance enhancements through JIT compilation, but preliminary implementations have shown to increase memory consumption as a side effect. 3. Concurrency improvements through better abstractions like streams and pipelines. When used, the running program would place itself inside an event loop, disable the GIL, and force objects to be immutable. Matz calls it Rube Goldberg Programming.

Mozilla has done a study of image formats and concluded that WebP and JPEG XR are not a big-enough improvement over well-optimized JPEG. In the study only HEVC (H.265) was significantly better, but it's a patent-encumbered format, so it can't be used freely ( shhhh!) -- ked tak pozeram, co to dokaze s textom a komixovymi obrazkami, mozno by to vedelo priniest zvysenie kvality aj nasim obrazkom ukladanym v JPEGu
