GCC and C vs C++ Speed, Measured
With the imminent release of gcc 4.8, GCC has finally switched to C++ as the implementation language. As usual, LWN has excellent coverage. Those with long memories will remember Linux trying to use g++ back in 1992 and retreating in horror at the larger, slower code. The main benefit was stricter typechecking…

Familiarity is the enemy: On why Enterprise systems have failed for 60 years
My thoughts on why enterprise knowledge systems have failed for sixty years, and what might finally replace them. A couple of weeks ago I demoed one part of what I have been building to a senior exec at a global enterprise - someone who had been asked to lead and guide

Linux CVEs, more than you ever wanted to know
It’s been almost 2 full years since Linux became a CNA (Certificate Numbering Authority) which meant that we (i.e. the kernel.org community) are now responsible for issuing all CVEs for the Linux kernel. During this time, we’ve become one of the largest creators of CVEs by quantity, going from nothing to number 3 in…

Notes on concurrency bugs
Do concurrency bugs matter? From the literature, we know that most reported bugs in distributed systems have really simple causes and can be caught by trivial tests, even when we only look at bugs that cause really bad failures, like loss of a cluster or data corruption. The filesystem literature echos this result …

Upgrading a motherboard’s BIOS/UEFI (the hard way)
A couple of weeks ago I found a really good deal on a Socket AM4 motherboard that supports the newest AMD Ryzen CPUs. The motherboard is an ASRock A520M/ac . It’s a very basic motherboard which doesn’t appear to be sold by any of the usual retailers anymore, but I couldn’t pass up on the deal, especially with the…

Bump Allocation: Up or Down?
Back in 2019, Nick Fitzgerald published always bump downwards, an article making the case that for bump allocators, bumping “down” (towards lower addresses) is better than bumping up. The biggest reasons for this are bumping up requires 3 branches vs 2 for bumping down and rounding down requires fewer instructions…

I’ve invested in a new odometer to help my car go faster. Accountability is important, and as a driver I believe the most important thing I can do is set measurable, achievable and inspiring goals for the people pushing my car down the road.

Demystifying programs that create programs, part 1: A disassembler
People appear to enjoy the blog posts about me porting different compilers to OpenBSD . What I would like to do for the next couple of posts beginning with this one is to take a step back and de-complexify these programs. Both the D compiler and the GNU Modula-2 compiler are highly complex pieces of software. But at…
