The NASA/ESA Hubble Space Telescope has captured the most detailed image yet of a close neighbour of the Milky Way — the Triangulum Galaxy, a spiral galaxy located at a distance of only three million light-years. This panoramic survey of the third-largest galaxy in our Local Group of galaxies provides a mesmerising…
My job involves a lot of staring at large numbers, mostly latencies in nanoseconds, and picking out magnitudes like microseconds. I noticed myself constantly...

This is a story about how I lost my data when trying to prevent it by backing it up.
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…
It seems like it was just six months ago that we announced Fedora 29, and here we are again. Today, we announce our next operating system release. Even though it went so quickly, a lot has happened in the last half year, and you’ll see the results in Fedora 30. If you’re impatient, go to […]
Ruby apps can use a lot of memory. But why? Various people in the community attribute it to memory fragmentation, and provide two “hacky” solutions. Dissatisfied by the current explanations and provided solutions, I set out on a journey to discover the deeper truth and to find better solutions.
Amazon is so new, and so dramatic in its speed and scale and aggression, that we can easily forget how many of the things it’s doing are actually very old.
By bert hubert / bert@hubertnet.nl This post is an excerpt of a far longer post on Galileo, its structures and the cause of the outage. Here we’ll only focus on the outage - the potential underlying reasons behind it are described in the full article. Since the week-long outage in July I’ve been fascinated by Galileo…

The first time Vayu Maini Rekdal manipulated microbes, he made a decent sourdough bread. At the time, young Maini Rekdal, and most people who head to the kitchen to whip up a salad dressing, pop popcorn, ferment vegetables, or caramelize onions, did not consider the crucial chemical reactions behind these concoctions.
Long ago as an undergraduate, I found myself back home on a break from school, bored and with eyes wandering idly across a family bookshelf. At school, I had started to find a calling in computing systems, and now in the den, an old book suddenly caught my eye: Tracy Kidder’s The Soul of a New Machine . Taking it off…
Mitchell J. Feigenbaum , a mathematical physicist whose groundbreaking work on deterministic chaos influenced fields ranging from cardiology to cartography, died in New York City on June 30 at the age of 74. Feigenbaum was the Toyota Professor and director of the Center for Studies in Physics and Biology at…
For the first “real” post in this blog, we’ll build an x86 assembler in less than 256 lines of C code. Obviously, it won’t implement every x86 instruction, but it will implement a surprisingly useful subset: data movement, control flow, integer arithmetic, bitwise operations, and function calls. We won’t be able to…
The essence of constraint is projection.
Three more fundamental algorithms in the series. Today, recursive permutations, subsets of the given set and variations with repetitions. Th...
Over the summer, I described preparing for my next expedition. I’m thrilled to announce that the expedition is now plotted, the funds are raised, and the bags are packed: together with Steve Tuck and Jess Frazelle , we have started Oxide Computer Company .
I have long wanted to create my own desktop operating system targeting the Raspberry Pi. I believe we should have a hackable desktop environment that is both powerful and lightweight, similar to BeOS and the Amiga. To build this desktop we really need full control over how apps draw to the screen, but still have…
In a previous post I outlined why programmers should strive to be good at one thing rather than everything. In this post I discuss how to ...
(Please be sure to read the addendum at the end of this post.) A week ago last Friday, I spoke to Joi Ito about the release of documents that accuse Media Lab co-founder Marvin Minsky of involvement in Jeffrey Epstein’s horrific crimes.* Joi told me that evening that the Media Lab’s ties to Epstein went… Read More »On…
