Who writes code? The obvious answer is that developers write code. Who makes sure the code works? Many companies have separate QA departments that are responsible for making sure code works. The answer to this question also seems obvious. MORE
We are explicit about our dependencies, so we know what code we need to run to run a specific component. Lazy-loading and bundle splitting can have a huge impact on page performance: less code requested, parsed, and executed. You can see a demo here (check the code source ). MORE
There was something gratifying in taking a code that takes minutes to run and make it run in a handful seconds. Normally the team decides how well to cover and test the code, and it’s important that all developers in a team know how to write tests. MORE
The first step towards this goal is the recently announced move of the HammerDB source code to the TPC-Council GitHub repository.

Developers sometimes give a cold shoulder to developers whose code is not up to par. Particularly in an industry as fast moving as the web development industry is, you cannot afford to wait until you are an “expert” to code. You have to code using the best ways you know how, and continue to learn. Yes, they will use the knowledge they have to get the job done, which results in some unseemly coding at times. MORE

Programmers want to write good code. High quality software includes many things, one of which is making code easy to modify/maintainable. There are always new versions with new features which obviously means that there is more code written. It makes sense. MORE

I recently improved flame graph code coloring. Code-type coloring was a regex hack that took five minutes.

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
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. Over time, our code becomes bloated, difficult to maintain and what should be simple little fixes can quickly turn into long walks through messy syntax. By using the system applied to coding, we can make our code more efficient and much easier to maintain. MORE

In concrete terms, here is the C code to compute the remainder of the division by some fixed divisor d : uint32_t d =. ; // your divisor > 0. A line of code like (n % d) = 0 is typically compiled to the computation of the remainder ( (n % d) ) and a test to see whether it is zero. I make my benchmarking code available. Not all instructions on modern processors cost the same. MORE
I expect that the compiler will turn this code into a sequence of instructions over 32-bit registers: uint32_t compilermod32 ( uint32_t a ) {. My source code is available. In software, compilers can often optimize away integer divisions, and replace them with cheaper instructions, especially when the divisor is a constant. I recently wrote about some work on faster remainders when the divisor is a constant. MORE
That’s because all code is technical debt. Developers often try to minimize the amount of technical debt they take on when building software. Many will even try to have “zero” technical debt. It sounds like a worthwhile goal. MORE
