When optimising code, never guess, always measure
This page has been Tagged As Software This is a truism that lots of people quote, but it can be hard to remember, especially in the heat of battle (as it were). Rather fortunately it came to mind just when needed, as I found something completely unexpected.

A guide to better embedded C++
Disclaimer: this, by no means, is not a definitive description of the whole embedded-specific development. This is just a small good practice about interaction with hardware.

Copying objects in JavaScript
In this article we will look at the various ways an object can be copied in Javascript. We will take a look at both shallow and deep copying.

Writing C for Curl
It is a somewhat common question to me: how do we write C in curl to make it safe and secure for billions of installations? Some precautions we take and decisions we make. There is no silver bullet, just guidelines. As I think you can see for yourself below they are also neither strange nor … Continue reading Writing…

Rare Greek Variables
I scrape Arxiv to find underused Greek variables which can add some diversity to math; the top 10 underused letters are ϰ, ς, υ, ϖ, Υ, Ξ, ι, ϱ, ϑ, & Π. Avoid overused letters like λ, and spice up your next paper with some memorable variables!

Firewalling your code
When writing code, you can call any function as long as it’s public, and similarly, you can access any object’s public properties or methods. Usually, access to code is all or none – a piece of code can be either public or private. Lately, I’ve been thinking about ways to implement more fine-grained access controls…

The Next Big Language
Dylan? C# 3? Perl 6? Does it have deterministic destructors, even as blocks like Python 2.5? Generics? A powerful macro system? Even as described it sounds like magic, but not a moment too soon.

Even faster asin() was staring right at me
I don't normally do follow-ups and never this quick. After posting that last article, it was fun to read the comments on Reddit and Hacker News as they rolled in. I even found other discussions . I couldn't help wonder, "Could I have made it even more performant?" . After heading home I decided to take another look.

The Sad State of the Backbone Ecosystem
For the past 2 years, ~90% of my coding time has been spent working on a large scale Backbone.js app. In February 2014, the Backbone community was in a fairly good place. The core library had reached 1.0 the previous year and had a strong team around it. Marionette had emerged as a de-facto standard for web…

Escaping strings faster with AVX-512
When programming, we often have to 'escape' strings. A standard way to do it is to insert the backslash character (\) before some characters such as the double quote. For example, the string my title is "La vie" becomes my title is \"La vie\" A simple routine in C++ to escape a string might look … Continue reading…
