Here’s a Python script which renders some Penrose tiling. Yes, this is valid Python code:_ =\ """if! 1:"e,V=100 0,(0j-1)**-.2; v,S=.5/ V.real, [(0,0,4 *e,4*e* V)];w=1 -v"def! E(T,A, B,C):P ,Q,R=B*w+ A*v,B*w+C *v,A*w+B*v;retur n[(1,Q,C,A),(1,P ,Q,B),(0,Q,P,A)]*T+[(0,C ,R,B),(1,R,C,A...

I’ve been getting some emails from young developers wanting to “level up” as programmers. I’m definitely not the first to write about this topic, so I’m not sure how much I have to add. Still, for what it’s worth here are a few points off the top of my head:Work with other developers. We are at a wonderful time in the history of technology when for the first time, it doesn’t really matter where you are or who you are working for. So long as you have a decent internet connection, you can pair up with another developer anywhere in the world and work...

Last week I got to take interviews to hire senior java developers with around 5 years of experience. But after the interview process is over I felt like the frameworks makes developers life easier but at the same time making them dumb.Everyone puts almost all the new frameworks on their resume claiming they have "Strong, working experience on Spring, Hibernate, Web Services etc".Here is how the interviews went on.Me: You have used Spring in your latest project. What are the advantages of using Spring?Interviewee: We can configure beans in XML and it will take care of instan...

Within our industry we use a huge range of terminology.  Unfortunately we don’t all agree on what individual terms actually mean.  I so often hear people misuse the term “Refactoring” which has come to make the business in many organisations recoil in fear.  The reason for this fear I’ve observed is because of what people often mean when misusing this term.I feel we are holding back our industry by not being disciplined in our use of terminology.  If one chemist said to another chemist “we are about to perform titration”, both woul...

I wrote a post about how to install MySQL++ and I thought I will write a quick tutorial on how to use it too.This is a very basic MySQL++ program and it’s very self explanatory:#include <mysql++.h>#include <stdlib.h> using namespace std;using namespace mysqlpp; int main() { try { Connection conn(false); conn.connect("DB NAME", "DB HOST probably localhost", "DB USER", "DB PASS"); Query query = conn.query(); } catch (BadQuery er) { // handle any connection or // query errors that may come up cerr << "Error: " << er...

A function is a group of related statements that accomplish a specific task. Understanding functions is a crucial step to programming in C++, as Brian Overland explains in this chapter from his book.The most fundamental building block in the programming toolkit is the function—often known as procedure or subroutinein other languages. A function is a group of related statements that accomplish a specific task. Once you define a function, you can execute it whenever you need to do so.Understanding functions is a crucial step to programming in C++: Without functions, it woul...

In this interview, co-author of Sams Teach Yourself C++ in 24 Hours, 5th Edition Rogers Cadenhead discusses moving from Java to C++, what brought him to C++, and the best tactics for learning C++.Danny Kalev: For how long were you a Java programmer? Can you tell us a bit about the nature of the projects in which you took part at that time?Rogers Cadenhead: I've been a Java programmer since the language was launched by Sun Microsystems in 1995. I was doing website development, and Java applets were the first available platform for creating interactive programs that ran ...

Brian Overland, long-time Microsoft veteran and author of C++ Without Fear: A Beginner's Guide That Makes You Feel Smart, 2nd Edition, shares 10 of his most hard-earned, time-saving insights from decades of writing and debugging C++ code.My first introduction to the C family of languages was decades ago (yes, I know this dates me horribly). Later I learned C++. I wish someone back then had steered me around the most obvious potholes; it might have saved me hundreds of frustrating hours.I can give you at least a few of those much-needed (excuse the term) pointers. This isn’t a tutor...
