FreeBSD/EC2 on C5 instances
Ever since the first EC2 instances launched — the ones which were retrospectively named "m1.small" — Amazon has relied on the Xen hypervisor. No longer: C5 instances use KVM. This sounds like it would be a problem, but in fact that change didn't bother FreeBSD at all: Now that everything uses hardware-based paging…

A Deep Dive into HandBrake and Video Transcoding
An obvious interest area of mine is in ripping (and watching) movies using my Mac. I've talked about everything from installing the tools I use to how I rip to how to make sure I update the ripping tools . And though I've included some comparison pictures in the how-I-rip article, I've never done a deep dive into the…

Debugging macOS Kernel Using VirtualBox
Update: In the HN discussion, awalton mentioned you can set CPUID flags in VMWare. Simply adding cpuid.7.ebx = "-----------0--------------------" to the vmx file will disable SMAP. Late last year, I upgraded my old MBP to the 2016 model with a Skylake processor. As I was debugging a kernel exploit, it turned out that…

Realizing Hackett, a metaprogrammable Haskell
Almost five months ago, I wrote a blog post about my new programming language, Hackett , a fanciful sketch of a programming language from a far-off land with Haskell’s type system and Racket’s macros. At that point in time, I had a little prototype that barely worked, that I barely understood, and was a little bit of…

Is Semantic Versioning an Anti-Pattern?
The classic X.Y.Z style of software numbering, sometimes known as Semantic Versioning, may be hurting more than it helps. Semver.org has codified how these numbers should be used for some cases, describing what is meant by the major and minor version numbers, when to change them, what

China is catching up to the USA, while Japan is being left behind

Why TDD isn't crap
After my recent vitriol about unit testing, a couple of people sent me Why TDD is Crap as a thorough debunking of TDD and unit testing. As someone very interested in software correctness, I ended up writing a debunking of his debunking. Transcriptions will be in quotes, my responses below. Some important notes: From…
