"I Don't Want To Maintain Their Code"

The reaction from one of the developers was simply: “I don’t want to maintain their code.” The worst code is always other people’s code. I recently heard of a situation where a team needs to hire someone since they’re understaffed. I understand this mentality. For most developers, this is simply fact. What is also fact is that very little software of significance gets built by the lone wolf. Building software is a difficult endeavour

Code Reviews Are Awesome. Sometimes

Professor Beekums

Code reviews are seen as an essential part of software development. It makes a lot of sense to say that a programmer should have their work reviewed by another programmer. Authors and journalists have their work reviewed by an editor after all. Humans make mistakes and creators especially get a little tunnel vision when they are focused on making their creations. Having someone else look at it can catch many errors

Coloring Flame Graphs: Code Hues

Brendan Gregg

I recently improved flame graph code coloring. Code-type coloring was a regex hack that took five minutes. My hack was the following eight lines of code: if (defined $type and $type eq "java") { if ($name =~ /::/) { # C++ $type = "yellow"; } elsif ($name =~ m:/:) { # Java (match "/" in path) $type = "green" } else { # system $type = "red"; }. And that's what I coded. I had similar issues with JIT'd code for Node.js.

Comments on timing short code sections on Intel processors

John McCalpin

I usually precede the code that I want to test with a “warm-up” loop consisting of at least a few seconds of execution of instructions using the same SIMD width as the code that I want to test. This is even more confusing when you consider vectorization and loop unrolling, which the compiler may change significantly from one compilation to the next as you fiddle with your code. For simple loops, you can look at the assembly code and count instructions.

More Manageable, Efficient Code Through 5S

Sometimes code turns ugly. We add quick fixes or enhancements and our code starts to become a big tangle of functions that aren’t laid out in any sort of organized fashion.

By using the system applied to coding, we can make our code more efficient and much easier to maintain.
