I'm trying to implement an algorithm able to search for multiple keys through ten huge files in Python (16 million of rows each one). I've got a sorted file with 62 million of keys, and I'm trying to scan each ten file in dataset to look for a key and its value.
Sorted file key:
a
b
c
d

What is better practice in big projects? Have all the flow in the main or functions which call to others functions?
I show better with two examples (in a invented language to be more legible).
Example 1 (all the flow in main):
function menu1
{
print "Select an option."
print "1. Cake."...

In the new design there was a change to the CSS that determines the fonts used for posts. This is what it is using now, based on my research:
font-family:'Helvetica Neue',Helvetica,Arial,sans-serif!important;
Overall I think it looks great, but there is a bit og an eyesore (in my opinion) w...
How to write a CSS font style for the following text decoration:
font-family: Comic Sans MS CSS rule doesn't work.

As the following image shows the font size of mathematical text and bolded text are larger than the ordinary text, at least in my browser (Chrome v47 on Mac osX):
The image is snapped from this answer. Could you please look into whether this is something which might be corrected, and/or is a p...
I've come across a user that I've seen on several occasions offer to assist others via TeamViewer. He will ask them to provide their ID and password. It appears that the user is positively trying to help and not attempting anything nefarious, but I have some concerns about this:

The Edit Review queue is notorious for people making mistakes in the process. The problem is almost entirely related to the fact that answer edits are much rarer than question edits.
Code Review has unfortunately got a lot of robo-reviewers in this queue, people who see a code edit - and auto-re...
Overall, your code is quite good. But there's always room for improvement:
Syntax & Spelling
Your question is tagged as python-2.7 so use print as a statement rather than as a function, or from __future__ import print_function.
Indexing with magic numbers, such as coords[1], is ugly. Prefer se...
LogToolWindowLoader.java
Constant or user property
Thread.sleep(1000);
This is a nice example of magic number.
It's better that you create at least a private static final int for it, but even better could be the possibility to change that value by a property file, with a default of 1000 if th...

I was pondering the close reason today and I can't think of an instance where a question that is on-topic for Code Review is too broad.
When is a question too broad? How could a too-broad question be edited to be acceptable?
