  • Detect *target* file size using JavaScript

    - by noblethrasher
    Hi, Would like to write a script to detect the file size of the target of a link on a web page. Right now I have a function that finds all links to PDF files (i.e. the href ends with '.pdf') and appends the string '[pdf]' to the innerText. I would like to extend it so that I can also append some text advising the user that the target is a large file (e.g. greater than 1MB). Thanks

    - by Chris
    I have a Windows CE console application that's entry point looks like this int _tmain(int argc, _TCHAR* argv[]) I want to check the contents of argv[1] for "-s" convert argv[2] into an integer. I am having trouble narrowing the arguments or accessing them to test. I initially tried the following with little success if (argv[1] == L"-s") I also tried using the narrow function of wostringstream on each character but this crashed the application.

  • Printing Variable names and contents as debugging tool; looking for emacs/Python shortcut

    - by Schof
    I find myself adding debugging "print" statements quite often -- stuff like this: print("a_variable_name: %s" % a_variable_name) How do you all do that? Am I being neurotic in trying to find a way to optimize this? I may be working on a function and put in a half-dozen or so of those lines, figure out why it's not working, and then cut them out again. Have you developed an efficient way of doing that? I'm coding Python in Emacs.

  • Exercise 7.9 in "How to Think Like a Computer Scientist (python)" measuring occurrences of a character in a string

    - by Abie
    The question is how to write a program that measures how many times a character appears in a string in a generalizable way in python. The code that I wrote: def countLetters(str, ch): count=0 index=0 for ch in str: if ch==str[index]: count=count+1 index=index+1 print count when I use this function, it measures the length of the string instead of how many times the character occurs in the string. What did I do wrong? What is the right way to write this code?

  • Basic LaTeX questions

    - by bpc89
    Two (hopefully quick) questions about LaTeX: How do you number select functions? I'm working in a documentclass{article}, if that matters. I want to have certain functions numbered such as function1 function2 (1) function3 function4 (2) How do you make a sign to evaluate an integral? I know how to do brackets, but is it possible to only make one straight light to the right of the function with the bounds of integration? I can't figure out how to do that.

  • When would isSearchable return false for an Oracle JDBC column?

    - by Ian Varley
    In what cases would a call to java.sql.ResultSetMetaData.isSearchable(int col) return false for an Oracle database? The documentation for the method doesn't really answer the question: "Indicates whether the designated column can be used in a where clause." I can think of only one case - when the column is the result of an aggregate function (in which case it would have to be part of a HAVING filter, not a WHERE filter). Are there any other cases?
