  Currying in Python

What is Currying? Currying is like a kind of incremental binding of function arguments. Let’s define a simple function which takes 5 arguments: 1def f(a, b, c, d, e):2    print(a, b, c, d, e) In a language where currying is supported, f is a function which takes one argument (a) and returns a function which takes 4 arguments. This means that f(5) is the following function: 1def g(b, c, d, e):2    f(5, b, c, d, e) We could emulate this behavior the...

  10 Web Design Elements that You Shouldn’t Overlook

When it comes to designing and building websites, it never seems to happen fast enough.Given this fast pace, many small details that are eventually required to build the website are often left out of the design process. While these details might be minor, they are what take a website from nice to truly awesome.These details are often easy to miss because they don’t drive the overall look and feel of the website. The problem is that as your development team works through the design, it wil...

  The trap of the performance sweet spot

This post is about JavaScript performance but I would like to start it by telling a story that might seem unrelated to JS. Please bear with me if you don’t like C.A story of a C programmer writing JavaScriptMr. C. is a C programmer as you can probably guess from his name. Today he was asked by his boss to write a very simple function: given an array of numbered 2d points calculate vector sum of all even numbered points... He opens his favorite text editor and quickly types somet...

  #46 – Why software sucks

No one makes bad software on purpose. No benevolent programmer has ever sat down, planning out weeks of work, with the intention of frustrating people and making them cry. Bad software, or bad anything, happens because making things is hard, making good things doubly so. The three things that make it difficult are: Possessing the diverse skills needed not to suck.Understanding who you’re making the thing for.Orchestrating the interplay of skills, egos and constraints over the course of...

  Comparing Floating Point Numbers, 2012 Edition

We’ve finally reached the point in this series that I’ve been waiting for. In this post I am going to share the most crucial piece of floating-point math knowledge that I have. Here it is:[Floating-point] math is hard.You just won’t believe how vastly, hugely, mind-bogglingly hard it is. I mean, you may think it’s difficult to calculate when trains from Chicago and Los Angeles will collide, but that’s just peanuts to floating-point math.Seriously. Each ti...

  Coding tricks of game developers

If you've got any real world programming experience then no doubt at some point you've had to resort to some quick and dirty fix to get a problem solved or a feature implemented while a deadline loomed large. Game developers often experience a horrific "crunch" (also known as a "death march"), which happens in the last few months of a project leading up to the game's release date. Failing to meet the deadline can often mean the project gets cancelled or even worse, you lose your job. So w...

  Thoughts on Python 3

I spent the last couple of days thinking about Python 3's current state a lot. While it might not appear to be the case, I do love Python as a language and especially the direction it's heading in. Python has been not only part of my life for the last couple of five years, it has been the largest part by far. Let there be a warning upfront: this is a very personal post. I counted a hundred instances of a certain capital letter in this text. That's because I am very grateful for all the opport...

  4 deployment modes of Redis

As a high-performance in-memory database, Redis is widely used in current mainstream distributed architecture systems. To improve system fault tolerance, using multiple instances of Redis is also inevitable, but the complexity is much higher than that of a single instance. This article mainly introduces the four deployment modes of Redis and their advantages and disadvantages.
