For educational purposes I've tried to implement a simple algebraic OOP example using CLOS. The functionality is as far as I can say as it is supposed to be.

This is for an instrumentation tool using the ASM tree api. This method assigns a handler to a field, which is used in instrumented methods.

Assume a 2D [n][n] matrix of 1's and 0's. All the 1's in any row should come before 0's. The number of 1's in any row I should be at least the number of 1's row (i+1). Find a method and write a C program to count the number of 1's in a 2D matrix. The complexity of the algorithm should be order n.

I wrote a program that generates a set of 1D cellular automaton. Basically, it generates this (rule 150):
...and rotates it to form this:
I then introduced an element of randomness to it, so it could form images like this:
I was hoping I could get reviews for the code I have, focusing around how to optimize it and i... |
I just created this during a live screencast. The people who were on there were very critical of almost every line of code. They say I am a horrible coder and know nothing. Looking at this tax calculator, would you say I'm an OK coder?

So I'm writing an abstraction layer that wraps a telephony RESTful service for sending text messages and making phone calls. I should build this in such a way that the low-level provider, in this case Twilio, can be easily swapped without having to re-code the higher level interactions.
I'm using a package that is pre-... |
I needed a class where I could store an instance of any type. The goal was an interface as follows:
class TypeMap {
template<typename T>
T& get();
};
Such that:
Iff &m1 == &m2 then &m1.get<T>() == &m2.get<T>().
The first call to m.get<T> for all m, T combinations returns a reference to a default-constructe... |
This is the existing code. Clearly way too much is going on in this index method and furthermore it's untested (and hard to test in its current form).
def index
# @s = ""
# @now=DateTime.now
@from = params[:from]? ('01/01/'+params[:from]).to_date : '01/01/1991'.to_date
@to = params[:to]? params[:to]+'/... |
This is used to change a Cyrillic word with a stress marker into the same Cyrillic word but with the stress marker separately represented as a number. As I want to return two values I pass two parameters by reference. I assume there is at most only one stress marker per word.
What could I improve here?

(!empty($student->former_name) ? print $student->former_name : '');
I only want to print out the former name if it is not empty, nothing else.
I imagine I do not need the else part of it, but I do not know how to do it like that without the else.
I want to shorthand this:
if(!empty($student->former_name))

I have just finished another page of my project and everything is working just great with the following code example.
My first concern is whether you could recommend something to make my code look more beautiful or probably more secure? As I have no user input, I suppose this code can not be SQL injected? For connecti... |
Here's my solution to Project Euler problem 40.
import operator
import math
def levels(n):
return 9 * n * 10 ** (n - 1)
def face_value(i):
def level_filler(i):
n = 1
yield 1
while i > levels(n):
yield int(levels(n)/n * 1.0)
i -= levels(n)
n += 1

Very simple requirements here:
connect to web service
check if account number exists
if it exists update it
if it does not exist create the account
I have accomplished this with the code below I am wondering if this is efficient and secondly if there is a better way of doing this.
