I believe it’s the ANSI standard. EDIT: Actually, I think it’s the SQL-92 standard. A later version of the standard appears to optionally allow for 128 character names, but Oracle doesn’t yet support this (or has partial support for it, insofar as it allows 30 characters. Hmmm.) Search for “F391, Long identifiers” on this page… … Read more
numpy.random.randint accepts a third argument (size) , in which you can specify the size of the output array. You can use this to create your DataFrame – df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list(‘ABCD’)) Here – np.random.randint(0,100,size=(100, 4)) – creates an output array of size (100,4) with random integer elements between [0,100) . Demo – import numpy … Read more
With the mouse, you can drag the window sizes around. Click anywhere on the mode line that is not otherwise ‘active’ (the buffer name is safe, or any unused area to the right hand side), and you can drag up or down. Side-to-side dragging requires a very precise click on the spot where the two … Read more
What you probably want to measure is the impact a package has if you were to add it to your app bundle. Most of the other answers will estimate the size of the source files only, which maybe inaccurate due to inline comments, long var names etc. There is a small utility I made that’ll … Read more

Here is how I would do it with jQuery (demo): CSS .container { width: … Read more
In my case I was calling the setState method before the build method had completed the process of building the widgets. You can face this error if you are showing a snackBar or an alertDialog before the completion of the build method, as well as in many other cases. So, in such cases you should … Read more
To get the width and height of the viewport: var viewportWidth = $(window).width(); var viewportHeight = $(window).height(); resize event of the page: $(window).resize(function() { });
As per the documentation, these are just synonyms. size() is there to be consistent with other STL containers (like vector, map, etc.) and length() is to be consistent with most peoples’ intuitive notion of character strings. People usually talk about a word, sentence or paragraph’s length, not its size, so length() is there to make … Read more
You need to seek to the end of the file and then ask for the position: fseek(fp, 0L, SEEK_END); sz = ftell(fp); You can then seek back, e.g.: fseek(fp, 0L, SEEK_SET); or (if seeking to go to the beginning) rewind(fp);
You can set an individual font size for the legend by adjusting the prop keyword. plot.legend(loc=2, prop={‘size’: 6}) This takes a dictionary of keywords corresponding to matplotlib.font_manager.FontProperties properties. See the documentation for legend: Keyword arguments: prop: [ None | FontProperties | dict ] A matplotlib.font_manager.FontProperties instance. If prop is a dictionary, a new instance will … Read more
