Are HLists nothing more than a convoluted way of writing tuples?
...tation which could accept arguments of these two very different shapes and transform them in a type safe way.
The ability to abstract over arity is likely to be of interest anywhere that fixed arities are involved: as well as tuples, as above, that includes method/function parameter lists, and case...
Why are floating point numbers inaccurate?
...for more detail, see: 675539944105574 / 4503599627370496.)
Now that we've transformed the third component into a fractional number, adding 1 gives the true mantissa.
Recapping the Components
Sign (first component): 0 for positive, 1 for negative
Exponent (middle component): Subtract 2(# of bits)...
O(nlogn) Algorithm - Find three evenly spaced ones within binary string
...x8). This step is O(n).
Find the polynomial q = p2, using the Fast Fourier Transform. For the example above, we get the polynomial q(x) = x16 + 2x13 + 2x12 + 3x10 + 4x9 + x8 + 2x7 + 4x6 + 2x5 + x4 + 2x3 + x2. This step is O(n log n).
Ignore all terms except those corresponding to x2k for some k in L...
How to pass parameters correctly?
...t needs to store a copy of that object (possibly to return the result of a transformation of the input without altering the input), then you could consider taking by value:
void foo(my_class obj) // One copy or one move here, but not working on
// the original object...

Select the values of one property on all objects of an array in PowerShell
...ter is syntactically simpler).
The script-block variant, allows arbitrary transformations; it is a faster - all-in-memory-at-once - alternative to the pipeline-based ForEach-Object cmdlet (%).
Comparing the performance of the various approaches
Here are sample timings for the various approaches,...
What's “P=NP?”, and why is it such a famous question? [closed]
... non-deterministic Turing-machine to a deterministic one, we can, however, transform non-deterministic finite automatons (like the regex parser) into deterministic ones (well, you can, but the run-time of the machine will take long). That is, we have to try every possible path (usually smart CS prof...
Why is processing a sorted array faster than processing an unsorted array?
...something when a condition is satisfied. This type of branch can be easily transformed into a conditional move statement, which would be compiled into a conditional move instruction: cmovl, in an x86 system. The branch and thus the potential branch prediction penalty is removed.
In C, thus C++, the...
How do you detect where two line segments intersect? [closed]
...l dot to zero with E. That vector I called P above, and I did the obvious transformation of E.
You now have:
A*P = C*P + F*P*h
(A-C)*P = (F*P)*h
( (A-C)*P ) / (F*P) = h

What is the difference between LR, SLR, and LALR parsers?
...t for me is an enormously useful fact. I build program analyzers and code transformers and parsers are necessary but "uninteresting"; the interesting work is what you do with the parsed result and so the focus is on doing the post-parsing work. Using GLR means I can relatively easily build working...
