Donation to Jupiter Broadcasting

Chris Fisher’s Jupiter Broadcasting pod/vodcasting started 8 years ago with the Linux Action Show: still their flagship show, and how I discovered them 3 years ago.  Shows like this give access to FOSS to those outside the LWN-reading crowd; community building can be a thankless task, and as a small shop Chris has had ups […]

BTC->BPAY gateway (for Australians)

I tested out livingroomofsatoshi.com, which lets you pay any BPAY bill (see explanation from reddit).  Since I’d never heard of the developer, I wasn’t going to send anything large through it, but it worked flawlessly.  At least the exposure is limited to the time between sending the BTC and seeing the BPAY receipt.  Exchange rate […]

Legal Questions About Localbitcoins.com and Australia

As my previous post documented, I’ve experimented with localbitcoins.com.  Following the arrest of two Miami men for trading on localbitcoins, I decided to seek legal advice on the sitation in Australia. Online research led me to Nick Karagiannis of Kelly and Co, who was already familiar with Bitcoin: I guess it’s a rare opportunity for […]

Pettycoin and working with limited visibility.

At linux.conf.au I gave a last-minute talk previewing my work on pettycoin (video, slides), an experiment to shard a bitcoin-like network.  The idea is to trade off some security and robustness in return for scale, but use it only for small amounts where fraud is less worthwhile.  On the bitcoin network today this is already […]

linux.conf.au 2014: Rusty’s Must See List

Delightedly finished reading through the linux.conf.au program.  Some nasty clashes have me still arguing with myself, but here are my personal compulsory attendance talks.  Your preferences will no-doubt differ, so I’ve tried to explain my reasons:   Tridgell: Open Hardware Differential GPS – I spoke to Tridge about this, and the abstract completely undersells it. […]

Git prompt for bash

I don’t know who wrote this originally, but this is from my .bashrc.  Tridge’s is simpler, but has colour! Before this, I avoided git branches in favour of multiple copies of repositories because I use my prompt to provide location.  This provided the missing piece… # Git me harder! __git_ps1 () {     local g=”$(git […]

On Linux-Kernel Mailing List Behavior

As raised recently by Sarah Sharp, the Linux Kernel mailing list (lkml) has a reputation as an intimidating place.  The context (covered so well by LWN) was that Greg Kroah-Hartman, the stable maintainer, is seen as a soft touch who accepts patches Linus wouldn’t. There’s been much uninformed discussion from those outside lkml, so let’s […]
