Here at Malwarebytes we are experiencing phenomenal growth, and since I have joined the company over 1 year ago in the Silicon Valley, one my main responsibilities has been to architect and develop several systems to power a fast-growing security company and all the needed infrastructure to support a product that is…
React is very popular at the moment, and I can see why: its developer ergonomics are very attractive. JSX and vDOM are really nice to work with, and it certainly enables composability. But, being the performance-minded person that I am, I wanted to test the claims that it's default-fast.
The size of binaries in the Nim programming language seems to be a popular topic recently . Nim’s slogan is expressive, efficient, elegant , so let’s examine the efficient part in this post by exploring a few ways to reduce the size of a simple Nim Hello World binary on Linux. Along the way we will:
If you just want to get in touch, you can talk to me in an emailwardly fashion here .
With the recent release of Ubuntu 15.04, aka “Vivid Vervet”, the Ubuntu community has also unveiled an early release of LXD (pronounced “lex-dee”), a new project aimed at revitalizing the use of LXC and LXC-based containers in the face of application container efforts such as Docker and rkt. In this post, I’ll provide…
The Go runtime, in addition to providing the usual services of garbage collection, goroutine scheduling, timers, network polling and so forth, contains facilities to enable extra debugging output and even alter the behaviour of the runtime itself.
Update: Two years later, I wrote a more detailed version of this article: My favorite bug: segfaults in Java (redux) .
Random code snippets, projects and musings about software from Eric Kidd, a developer and occasional entrepreneur.
Earlier this week, someone who goes by slipstream (“pulling data out of DPRK’s ass since 2014!”) posted a torrent of North Korea’s Red Star 3.0 installer. My first instinct was to download and run it, because installing software from North Korea, what could possibly go wrong?
Let's start by looking at a simple C function to be compiled as position-independent code (i.e. -fPIC , for use in a shared library):
In this post I explore the Amazon ECS architecture and what this architecture enables.
(This is the first of a series of technical posts I intend to write, and my goal is to help other engineers learn from the experience of…
First, no, I don't do every thing in assembly. I use other languages too. Assembly language does have its place though. Second, a few of my points may not apply to highly complex processors; for example, self-modifying code may not work on a processor with an instruction cache .
As a PSA (public service announcement), I'm reporting here that updating your Yosemite system to 10.10.3 is incredibly toxic if you use WiFi...
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
So, Windows 10 has just been released, and with it Ahead Of Time (AOT) compilation feature .NET native . Google also just recently introduc...
TL;DR: The JVM by default exports statistics by mmap -ing a file in /tmp (hsperfdata). On Linux, modifying a memory mapped file can block until disk I/O completes, which can be hundreds of milliseconds. Since the JVM modifies these statistics during garbage collection and safepoints, this causes pauses that are…
I’m often surprised how long software can keep trying to use compatibility features ages after their best-by date. Now that GCC 4.8 builds on Tige...
I think that all other considerations are of the extrinsic real-world kind – domain modeling, usability, schedules, platforms, etc. I also think that I can show how any "good" programming practice is mainly aimed at minimizing redundancy, dependencies, or both. I even think that you can tell a "good" programmer from a…
Yet another proprietary tech titan turns to the free OpenBSD operating system as their source of innovation in the networking and security ...
