All of this mounting technical debt could easily be avoided by giving each loop its own count variable. Having them recycle the same one creates a compile-time dependency of what’s going on in each loop with what happened in the loop before, even though there are no other similar dependencies in evidence. In other words, recycling this local variable is the only thing that’s creating a coupling in your code–there’s no logical reason to do it. Return it. Get the deposit back. Then buy yourself a new local variable.

Recently I was intrigued by Joe Kunk's On VB column about commenting code. I especially liked Kunk's comment that: "It's important to communicate what the code should be doing." I thought that was the best description of what comments should do that I'd read in a very long time. I also think it's the only thing comments should do. Comments should explain the "why" of the code and stop there. An age-old topic: what do you think comments should do?
|
|
|
|
|
That depends. On production code I expect only things that aren't obvious to be documented.
Yet, stupid comments like:
i++;
Are excelent comments if your purpose is to create a real beginner's tutorial.

|
|
|
|
I always comments code shortly every few lines of code, typically a block of code, and always during the code writing.
The goal is to arrive to read directly the comments while you review the code for any reason.
IMHO this is the best and most useful and productive approach.

You might be familiar with the triangular numbers: the number of objects that form equilateral triangles.... But what about the hollow triangular numbers? The ones where you take the middle blobs out of the triangles and just leave the border. The pattern there is very simple. They are all multiples of three. Then, shalt thou count to three. No more. No less. Three shalt be the number thou shalt count.

As much as I enjoy the math articles here, this is really dumbed down for non-CPians. It's divisible by 3 because there are three equal sides. Any empty polygon of n sides and k balls per side is a multiple of n or n * (k - 1). The first comment in there nails it.

Freeze Panes has been our most requested feature for quite a while, and we now support viewing workbooks that contain freeze panes. That means you can see all of those column headings at the top of your sheet all the time, as opposed to scrolling up and down as you've done in the past. That's just one of the improvements the Excel team rolled out to the web. Read on for more.

I’m not ashamed to admit that I’ve been using spreadsheet software since the 80′s (props to my dad and brother for turning me ontoVisiCalc during the Apple IIe days). I’ve also been in love with the predominant spreadsheet software, Microsoft Excel, more or less since its inception.... And yet I don’t have Excel on my personal computer. Why? Because while Excel is certainly a very powerful software application with a wide range built-in functionality as well as a plethora of outstanding bells and whistles, my experiences over the past few years has suggested to me that Excel is simply incapable of handling the immense data sets that are fast becoming the norm in today’s (and tomorrow’s) enterprise business landscape. Software engineering and data science offer more flexible rows, columns and functions.

Before Sid Meier was Sid Meier—the iconic video game designer whose name is stamped on classic titles like Pirates! and Civilization—he was just another computer hacker.... Meier, who had graduated with a degree in computer science before there was a personal computer in every home, spent his spare time reading hacker magazines, fiddling with code on his Atari, and building his own versions of arcade games like Space Invaders and Pac-Man. At one point he made a space game and put it up on his office network; it hooked so many employees that his bosses forced him to take it down. From Hellcat Ace to Ace Patrol, a walk through the games that made Sid great.

This is one of the most complete collection of things a developer should do and things he/she should avoid.
Must read for all software developers and technical leads.

You already know that we have been working on ReSharper 8 for quite a while, improving navigation, extending the scope of XAML support and introducing a project dependency viewer, among a plethora of other improvements. We’re setting our sights beyond the immediate 8.0 release though: for several months now, a part of the team has been working on something entirely new yet requested for a couple of years already: support for C++ in Visual Studio. C++ is not an easy language to write a parser for. Here's why.

MineAssemble is a tiny bootable Minecraft clone written partly in x86 assembly. I made it first and foremost because a university assignment required me to implement a game in assembly for a computer systems course. Because I had never implemented anything more complex than a "Hello World" bootloader before, I decided I wanted to learn about writing my own kernel code at the same time. Building better worlds... one instruction at a time.

Modern web browsers can leverage the ubiquitous graphics processing unit (GPU), both in mobile and desktop, to accelerate page rendering. This is particularly suitable for popular CSS features such as animation, transition, opacity, transformation, and many others. Web developers however need to ensure that all the bits and pieces work well to achieve the ideal 60 frames per second. Lights! Camera! Stylesheets!

Starting 3D programming is not an easy task to accomplish. There are a lot of new things that come into play, and they vary from choosing a programming language to selecting the correct 3D modeling software. These 10 goals are the things that when they are done, no matter in what language and with what rendering engine, you can consider yourself a semi-expert on this matter. Begin by doping the pure silicon for your transistors...

The Priceonomics blog is one of my favorites so when I saw that they had a programming puzzle up I decided to have some fun with it. And what’s more fun than hacking around with a quirky, esoteric programming language? I remember having fond memories of playing around with Prolog in middle school so decided to dig it up again in an attempt to solve this puzzle. Define a set of equations and tell Prolog to “solve for X”.

To be honest, 3-D printing technology just isn’t there yet for consumers. It’s expensive. It’s relatively lousy. And it takes a slew of skills--from technical to artistic--to produce anything worth printing in the first place. So specialists, like designers and engineers, can enjoy its rapid fabrication, and everyone else is left behind. Today, Microsoft announced a crucial step to empower the next wave of 3-D printer adoption. Windows 8.1 will be the first OS to support 3-D printing natively on desktops and tablets.

Late last month, Microsoft announced a raft of interface changes that Windows 8.1 would introduce. We've been giving them a spin. As you might guess from the name, Windows 8.1 is an update to (and improvement on) Windows 8. The new user interface introduced in that operating system—the Start screen, touch-friendly "Modern" apps, the charms bar—is retained in Windows 8.1. What we see is a refinement and streamlining of these concepts. Were you right to wait for the point release?

We all use the internet almost every day and share the likes of photos, new work and personal information. Taking matters of privacy into his own hands, an internet user by the name of Sang Mun has developed a font which cannot be read by computers. Entitled 'ZXX' the font has been designed in such a way that computers with Optical Character Recognition (OCR) will not be able to recognise it. You might also be interested in our "Left-handed Cursive" and "Captcha" fonts.

The program uses a simple genetic algorithm to evolve random two-wheeled shapes into cars over generations. Loosely based on BoxCar2D, but written from scratch, only using the same physics engine (box2d). The last of the V8 Interceptors... a piece of history! (Works best with shiny Chrome.)

Petition to Pardon Snowden to Receive White House Response.
With two weeks to go, they already have 119,000 signatures (well over the 100,000 requirement). Apparently, they can give a non-response response for ongoing investigations. Given the amount of attention this story has received, hopefully they will give a worthwhile response.
