Right ;-)
> Python is really not slower on modern computers than fortran on old ones - what an idea. And if Fortran would be better, people would not have switched to Python because of all its enormous development speed benefits.
Changing the comparison from runtime speed to "development speed", is not a compelling argument that Fortran is slower. Try again to explain why Python is more popular. It's really not that hard to figure out.
For scientific applications where speed matters, python libraries such as NumPy, SciPy, petsc4py, dolfin from FEniCS and PyClaw are typically being used, with a self implemented FORTRAN application, it would be remarkable to come close performance wise to these heavily performance optimised libraries.
> Obviously virtualisation is important - in the non-embedded market - but nobody runs 3 levels; and no - containerisation is not virtualisation, idiot!
Running JVM on Docker on AWS. Your hubris is laughable.
What an idiotic remark from this Anonymous Coward. Can't you read? Containerisation is not virtualisation. When running a JVM, instructions are translated from bytecode into native code; so yes that counts. But Docker, nah. AWS sure, VMWare counts too. So yeah 2 levels are often applicable. 3 levels? Nah, that's just marketing, misrepresentation and stupidity. Java remains important, obviously, but it isn't a large "growth language", applicable to the last 5 years evolution.
> Not a lot of people develop on macs - and as Apple fumbles to get things right and their margins reach astronomical heights and MacOS becomes less appealing, their value proposition becomes less and less interesting.
Macs have been a standard developer platform starting ~2009 on the west coast of the USA. Even today, if you work at a brand-name recognized company (Walmart, JPMorganChase, etc) you'll probably be using a Mac. Same with any funded startup. There are exceptions, but those companies are universally doomed or are MSFT.
As I pointed out before; this post reads like it's from 2015, ignoring the fact that its 2020. Obviously we still see a lot of Macs, but the developer tendency is to move away from those as the value proposition declines: higher prices, not enough performance for the buck and since Catalina, MacOS has become much more frustrating. Many startups and new purchases are looking elsewhere. Welcome to 2020!
