> Venezuela? But do they even have electricity for running servers? Venezuela isn't a third world country. Yes, they have electricity (and it is very cheap, hence a lot of BTC mining there).

Similarly, in CPython function-local variables are faster to access than class or module attributes (with the usual bunch of exceptions you always have in Python). This probably applies to similar languages (like Ruby) as well.

> Cython I wonder why everyone in this thread thinks that Cython works with CPython-incompatible implementations (like MicroPython or Zerynth)?

Python has a large performance disadvantage compared to C/C++. However, it is much faster to develop even by less skilled workers, thus quicker time to market and lower cost of development.

Cython is not an implementation of Python. Cython is a weird and difficult to use mix of C and Python, where most Pythonic constructs are translated to CPython API calls that are essentially the same API calls that the Python VM would do fo

GPU servers nowadays use proprietary form factors for GPUs anyway (like SXM2).

The Python REPL notoriously uses >>>/... like in the screenshot, ẃith the effect that e.g. IPython has a special paste-from-repl magic just to remove these.

That point of view seems rather uninformed, because industrial and residential pricing of electricity, gas etc. are virtually unrelated, and the former doesn't include new extra taxes for renewables in any country I know.

Sometimes I wonder whether actual optimization (as a craft, if you like) has been poisoned by scripting languages (Python etc.) and frameworks. For one thing they completely changed how the speed of computers is perceived, e.g. it is actua

Bloom filters don't seem useful as the primary means of deduplication for an actual data storage system to me. - False positives means marking data as duplicate when it's not. - Bloom filters are not associative. So unless the a

There is a funny mode on ARM processors (turned on in some images, by default) which causes unaligned reads to silently return bogus data (just increasing a kernel counter). PowerPC, and really, most non-x86 architectures, do this one way o

Kinda. Modern (newer than ~10 years) modern controllers are quite flexible, so you can pretty much populate any number of DIMMs in any slots (apart from wrong ordering, though this is not a IMC restriction, rather firmware, for stability).

Standard office computer here is a quad core (AMD APU), and it actually makes quite a bunch of stuff faster (e.g. conversion of scanned documents) compared to the previous-generation dual cores.

This is a HEDT processor that comes in the package of their server processors (up to four dice and eight memory channels, over 4000 pins total). These are large, because there's a lot in them ;) The desktop series has a more usual size

Operating systems were written in high(er) level languages a number of years before C, or UNIX, were invented.

These are "just" some free symbols (o, I, L) used with overloaded operators (!, |, --). The rest is pretty formatting with whitespace which isn't relevant to functionality.
