Golden Rule of Dependency Management
There’s a huge amount of complaining and problem solving for various dependency management solutions (particularly maven, but ivy and friends certainly aren’t immune). Problems range from having optional dependencies unnecessarily included to having duplicate classes or class conflicts and the solutions tend to be complex and involve a lot of trade offs. All these problems […]

Raspberry Pi forever – getting the SD card(s) to work along with some numbers and graphs
I have finally got my hands on the awesome Raspberry Pi board with a vicious plan of running a hardened Gentoo on it of course ;] But before that could happen, I had to get a decent SD card for it, which turned out to be not that obvious. There’s a wiki page with a […]

Minimise Configuration
Having configuration differences between development and production is largely unavoidable, but it’s important to keep the number of differences to a minimum to avoid unexpected bugs appearing in production that don’t occur in development mode. More than that though, it’s important to minimise configuration. Configuration is Code Often things are put in configuration files so […]

Default MPROTECT restriction for Firefox and Thunderbird on Gentoo Hardened
Good news! The Firefox and Thunderbird ebuilds in the portage tree disable JIT by default, using the two configuration options I’ve posted about before. Instead of using the pax_kernel USE flag, they incorporate the jit flag, which is by default disabled on the hardened profile. So, to make the long story short – if you […]

Passing a Torch
It is hard to let things go sometimes. Porting Linux to the VAX architecture taught me a lot about the detail of how Linux works, as well as how computer hardware and operating systems interact. It both removed the air of mystery about the kernel, and opened my eyes to the complexity of the GCC […]

Default to Development Settings
Most systems have multiple configuration profiles – one for production, one for development and often other profiles for staging, testing etc. Minimising differences between these configurations is critical but there are inevitably some things that just have to be different. This then leaves the question, what should the default settings be? There are three main […]

Juries and Complex Subjects
There is a lot of discussion at the moment about the Oracle v Google trial today, mostly centring around how impossible it is for the jury to understand the very technical concepts involved in the case. As Daring Fireball puts it: How could a randomly-selected jury possibly decide this? No knock intended against the jurors themselves — […]

Joho the Blog » Will tablets always make us non-social consumers?
I thus think (= hope) that it’s a mistake to extrapolate from today’s crappy input systems on tablets to a future of tablet-based couch potatoes still watching Hollywood crap. We’re one innovation away from lowering the creativity hurdle on tablets. Maybe it’ll be a truly responsive keyboard. Or something that translates sub-vocalizations into text (because […]

Go Faster By Not Working
We all know by now that continuous integration is part of good software development – check in regularly and have a suite of automated tests run to confirm that everything is working as expected. If a test fails, jump on it quickly and get the build back to green. Simple right? But what happens when […]
