What Haskell representation is recommended for 2D, unboxed pixel arrays with millions of pixels?
...duction). The cost of array construction often out-weights the benefits of faster random access, to the point that a list-based representation is faster in some of my use cases.
STUArray could have helped me, but I didn't like fighting with cryptic type errors and efforts necessary to write polymor...
MongoDB or CouchDB - fit for production? [closed]
... replication from a master-db to several clients with different documents.
Fast pre-calculated data like "how many parts do I have with this attribute and that filter, fitting to those conditions"

Our shops are now running much faster than with MySQL (and mysql-database needed additional...
Why are primes important in cryptography?
...) every possible number between 2 and that large prime number. Even on the fastest computers, it will take years (even centuries) to factor the kinds of prime numbers used in cryptography.
It is the fact that we don't know how to efficiently factor a large number that gives cryptographic algorithms...
What is the proper way to use the node.js postgresql module?
... connected to your
backend your entire app is bottleknecked based on how fast postgres
can respond to queries. It literally will line everything up, queuing
each query. Yeah, it's async and so that's alright...but wouldn't you
rather multiply your throughput by 10x? Use pg.connect set th...
How can I concatenate two arrays in Java?
...jects and use System.arraycopy() to ensure that copying large arrays is as fast as possible.
For two arrays it looks like this:
public static <T> T[] concat(T[] first, T[] second) {
T[] result = Arrays.copyOf(first, first.length + second.length);
System.arraycopy(second, 0, result, first...
Difference between CLOCK_REALTIME and CLOCK_MONOTONIC?
...Garvin for some value of "better", perhaps — CLOCK_MONOTONIC_RAW may run fast or slow of real time by several (or several hundred) parts per million, and its rate might vary due to environmental conditions like temperature or voltage (or steal time on virtual machines). On a properly-working machi...
why is plotting with Matplotlib so slow?
...netheless, there is a gui-neutral way of doing it that is still reasonably fast.
import matplotlib.pyplot as plt
import numpy as np
import time
x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)
fig, axes = plt.subplots(nrows=6)
fig.show()
# We need to draw the canvas before we start animating...

Best way to remove from NSMutableArray while iterating?
...:
It's been noted in other answers that the inverse formulation should be faster. i.e. If you iterate through the array and compose a new array of objects to keep, instead of objects to discard. That may be true (although what about the memory and processing cost of allocating a new array, and di...
What's the best way to set a single pixel in an HTML5 canvas?
...ers you care about for maximum speed. As of July 2017, fillRect() is 5-6× faster on Firefox v54 and Chrome v59 (Win7x64).
Other, sillier alternatives are:
using getImageData()/putImageData() on the entire canvas; this is about 100× slower than other options.
