I stand corrected, and I think I've figured it out. Even without burning fuel, in a frictionless system, the decelerating piston would be putting its energy back into the crankshaft? So it draws energy then puts it back every 180 degre

by vegabook 11y ago
well burning more fuel certainly increases output, but isn't it the case that the forcing the compression takes energy? That must be found from somewhere? Supercharged engines are generally less efficient than turbocharged engines, as

It's interesting how at the high end the piston engine increasingly looks like a jet turbine. In the 919 we essentially have more than half the energy created by a rotating set of turbos, capturing a part of the huge energies usually e

I have been using Python for a decade, and intensively for 7 years. I am a domain expert (finance) but I do also have 4 years of CS so consider myself non-idiotic, if not haskell-genius, on programming languages. I adopted Python (before it

There is a very clear cost for many new projects: infinite... for the simple reason that some key libraries still do not do Python 3 at all. Let's be clear. Cassandra is the best large ingest nosql database out there. Python 2 only o

Then why do we have an official concurrency module? If there is "no single solution fully addressing every use case", why do we have one official solution? Which the main post criticises? If you are correct that there is no single

What is the point of this comment? How am I incorrect? My points are: 1) Python 2.7 is still, 6 years later, much more popular than Python 3.x. 2) Python 3.x now has 5 versions, none of which has features which are strong enough to cause mi

A community which changes its mind every few years is a community which does not have effective leadership. Python's leadership is ineffective because 3.x has erased its credibility. You have maximum one opportunity to change a languag

Amen buddy. I hack in Python. I discover in Python. I script, and I pre-production in Python. Then I do C or Java or even JS. But none of my pro-code would have been possible without all the learning I accumulated about the problem in good

So we're in 3.5 already, and one of its central features, async, is flawed, you say. So not only do we not have a killer feature, but even one of the nice-to-haves is a dog. Timeout. This project needs new leadership. The competition (

I know it's not easy to graft multicore onto Python. So why pretend? If you're serious about web programming you're not using Python anyway. You're using JS or Golang. And if you insist on python, we have plenty of optio

In other words, a lost opportunity. Asyncio and this new syntax is both hard for beginners and experienced python coders alike, and still doesn't do multicore! . We're clocking up 3.x version numbers as if this will magically pro

Point taken on the total system power, but it's still 165 watt TDP. Agreed for "burst" workflows it'll be fine. But how many people have "burst" workflows that need a mobile 980? This thing is for gamers and

This thing guzzles up to 300 watts under load. There is no way this chip is not going to be throttled to death in a laptop form factor, unless the laptop itself makes more fan speed than a 747. I personally own a Gigabyte Brix Pro i7 and

I am intrigued by Nim. Does it have a REPL though? I think an official REPL (not a third party hack) is mandatory for scientific/numerical computing. Ocaml is the only compiled language I can think of which has a credible REPL, officia

Cython, Numpy, Numba (and others) are what make me skeptical that any of the numerical computing competitors to Python (Julia, or to a lesser extent Lua/JS/Clojure even compiled Scala etc) can displace it at. Why would you abando

yes. The constant threat of a big dominating presence of the authorities in the market, causes two-way flows to decline. You cannot rely on your macro skill set anymore to analyze the market direction, as anything you do is subject to polic

But your original post went to some length trying to show that this "news story" was a fake. If you were right, then the author of the story was expressing a bias, an opinion, an attempt to influence, a "message". Gees -

Because moving a pointer around and clicking on stuff is essentially quite a low-dimensional interaction. There are a bunch of things on screen and each is either clicked or not (okay, maybe hovered), at a fairly slow pace. The typical 87-k
