Call me maybe: Aerospike
Previously, on Jepsen, we reviewed Elasticsearch’s progress in addressing data-loss bugs during network partitions. Today, we’ll see Aerospike 3.5.4, an “ACID database”, react violently to a basic partition.

Call me maybe: Elasticsearch 1.5.0
Previously, on Jepsen , we demonstrated stale and dirty reads in MongoDB . In this post, we return to Elasticsearch, which loses data when the network fails, nodes pause, or processes crash.

The compiler flag that time forgot

Nim binary size from 160 KB to 150 Bytes
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.

Falling Into The Pit of Success
Eric Lippert notes the perils of programming in C++: I often think of C++ as my own personal Pit of Despair Programming Language. Unmanaged C++ makes it so easy to fall into traps. Think buffer overruns, memory leaks, double frees, mismatch between allocator and deallocator, using freed memory, umpteen dozen

Do Not Disclose Your Salary to Recruiters
Recruiters are not my most favorite people in the tech eco-system. They’re the people that will contact you on behalf of some client (the company that pays them) in order to try to find new employees. They typically get paid a fairly hefty sum per employee found and if ever there was a moment when the ‘you are the…

Energy Is Not Conserved (2010)
I’ve been meaning to link to this post at the arXiv blog , which is a great source of quirky and interesting new papers. In this case they are pointing to a speculative but interesting paper by Martin Perl and Holger Mueller, which suggests an experimental search for gradients in dark energy by way of atom…

I was underpaid for years and I didn't know it
The recent hashtag #talkpay on Twitter reminded me of a situation I found myself in at a former job. I contracted with a local startup during my last few years of college, and they gave me a job offer the winter before I graduated. The $40,000/year offer would expire in a week, and I wasn''t prepared to try to get…

Porting a NES Emulator from Go to Nim
Let me get this straight. We have an emulator for 1985 hardware that was written in a pretty new language (Go), ported to a language that isn’t even 1.0 (Nim), compiled to C, then compiled to JavaScript? And the damn thing actually works? That’s kind of amazing.

My Apple Watch After 5 Days
Having known about the Apple Watch for some time and knowing lots of my friends were planning to buy one, I was sceptical as my needs are quite different to that of those of the sighted and hearing. I have to rely on specific accessible features. However, I was curious as Apple products have b...

Four MLs (and a Python)
I wrote a small command-line text processing program in four different ML-derived languages, to try to get a feel for how they compare in terms of syntax, library, and build-run cycles. ML is a fam…

There are now at least eight Chromium-based Android default browsers
Google Chrome is not the default browser on Android 4.3+. There are now at least eight Chromium-based Android default browsers, and they are all subtly, though not wildly, different.
