Dynamically changing font size of UILabel
...
Single line:
factLabel.numberOfLines = 1;
factLabel.minimumFontSize = 8;
factLabel.adjustsFontSizeToFitWidth = YES;
The above code will adjust your text's font size down to (for example) 8 trying to fit your text within the label.
numberOfLines = 1 is mandatory.
Multiple l...
Are there any O(1/n) algorithms?
...east until some limit, enforced by the hardware (precision of the numbers, minimum of time that sleep can wait, time to process arguments etc.): this limit would then be a constant lower bound so in fact the above function still has runtime O(1).
But there are in fact real-world algorithms where th...
How to use timeit module
...l, but it's equivalent) for 1000 inputs; then repeat 7 times, and take the minimum. You need the averaging over 1000 inputs because you want the average (not best-case) algorithm complexity. You need the minimum for precisely the reason you gave. I thought I can improve your approach by choosing one...
Is there such a thing as min-font-size and max-font-size?
...
No, there is no CSS property for minimum or maximum font size. Browsers often have a setting for minimum font size, but that’s under the control of the user, not an author.
You can use @media queries to make some CSS settings depending on things like scre...

...en accurate sleeps within several milliseconds of that time when above the minimum 10-13ms.
Update:
Like mentioned in the docs cited below, it's common to do the sleep in a loop that will make sure to go back to sleep if it wakes you up early.
I should also mention that if you are running Ubuntu y...

How many threads is too many?
...he following features (which I believe are essential for performance):
a minimum number of active threads.
a maximum number of threads.
shutting down threads that haven't been used for a while.
The first sets a baseline for minimum performance in terms of the thread pool client (this number of t...
Minimizing NExpectation for a custom distribution in Mathematica
...e takes a long time to compute, even for a single evaluation. Now, the FindMinimum or similar functions try to find a minimum to the function. Finding a minimum requires either to set the first derivative of the function zero and solve for a solution. Since your function is quite complicated (and pr...
Should I impose a maximum length on passwords?
I can understand that imposing a minimum length on passwords makes a lot of sense (to save users from themselves), but my bank has a requirement that passwords are between 6 and 8 characters long, and I started wondering...
