I have reached the point in my life where I needed to write my first program in golang. I pondered for a disturbingly long time what exactly to write, but then it came to me…
Back in the day Google had an internal short URL service (think bit.ly, but for internal things). It was called “go” and lived at http://go. So what should I write as my first golang program? go of course.
The implementation is on github, and I am sure it isn’t perfect. Remember, it was a learning exercise. I mostly learned that golang syntax is a bit bonkers, and that etcd hates me.
This code stores short URLs in etcd, and redirects you to the right place if it knows about the short code you used. If you just ask for the root URL, you get a list of the currently defined short codes, as well as a form to create new ones. Not bad for a few hours hacking I think.
The pyconau call for proposals is now open, and runs until 28 May. I took my teenagers to pyconau last year and they greatly enjoyed it. I hadn’t been to a pyconau in ages, and ended up really enjoying thinking about things from topic areas I don’t normally need to think about. I think expanding one’s horizons is generally a good idea.
Should I propose something for this year? I am unsure. Some random ideas that immediately spring to mind:
something about privsep: I think a generalised way to make privileged calls in unprivileged code is quite interesting, especially in a language which is often used for systems management and integration tasks. That said, perhaps its too OpenStacky given how disinterested in OpenStack talks most python people seem to be.
nova-warts: for a long time my hobby has been cleaning up historical mistakes made in OpenStack Nova that wont ever rate as a major feature change. What lessons can other projects learn from a well funded and heavily staffed project that still thought that exec() was a great way to do important work? There’s definitely an overlap with the privsep talk above, but this would be more general.
a talk about how I had to manage some code which only worked in python2, and some other code that only worked in python3 and in the end gave up on venvs and decided that Docker containers are like the ultimate venvs. That said, I suspect this is old hat and was obvious to everyone except me.
something else I haven’t though of.
Anyways, I’m undecided. Comments welcome.
Also, here’s an image for this post. Its the stone henge we found at Guerilla Bay last weekend. I assume its in frequent use for tiny tiny druids.
This is the second book in the Leviathan Wakes series by James SA Corey. Just as good as the first, this is a story about how much a father loves his daughter, moral choices, and politics — just as much as it is the continuation of the story arc around the alien visitor. I haven’t seen this far in the Netflix series, but I sure hope they get this right, because its a very good story so far.

For someone who didn't intend to wreck the solar system's fragile balance of power, Jim Holden did a pretty good job of it. While Earth and Mars have stopped shooting each other, the core alliance is shattered. The outer planets and the Belt are uncertain in their new - possibly temporary - autonomy. Then, on one of Jupiter's moons, a single super-soldier attacks, slaughtering soldiers of Earth and Mars indiscriminately and reigniting the war. The race is on to discover whether this is the vanguard of an alien army, or if the danger lies closer to home.
I registered for city2surf this morning, which will be the third time I’ve run in the event. In 2016 my employer sponsored a bunch of us to enter, and I ran the course in 86 minutes and 54 seconds. 2017 was a bit more exciting, because in hindsight I did the final part of my training and the race itself with a torn achilles tendon. Regardless, I finished the course in 79 minutes and 39 seconds — a 7 minute and 16 second improvement despite the injury.
This year I’ve done a few things differently — I’ve started training much earlier, mostly as a side effect to recovering from the achilles injury; and secondly I’ve decided to try and raise some money for charity during the run.
Specifically, I’m raising money for the Black Dog Institute. They were selected because I’ve struggled with depression on and off over my adult life, and that’s especially true for the last twelve months or so. I figure that raising money for a resource that I’ve found personally useful makes a lot of sense.
Aptira is in an interesting position in the Open Source market, because we don’t usually sell software. Instead, our customers come to us seeking assistance with deciding which OpenStack to use, or how to embed ONAP into their nationwide networks, or how to move their legacy networks to the software defined future. Therefore, our most common role is as a trusted advisor to help our customers decide which Open Source products to buy.
(My boss would insist that I point out here that we do customisation of Open Source for our customers, and have assisted many in the past with deploying pure upstream solutions. Basically, we do what is the right fit for the customer, and aren’t obsessed with fitting customers into pre-defined moulds that suit our partners.)
That makes it important that we recommend products from companies that are well engaged with their upstream Open Source communities. That might be OpenStack, or ONAP, or even something like Open Daylight. This raises the obvious question – what makes a company well engaged with an upstream project?
I’ve been running my personal blog on a very hacked version of blosxom for a hilariously long time, and its time to escape. I’ve therefore started converting all of the content to wordpress here, and will eventually redirect the old domain to here as well.
Why blogging when its so 2000? I’m increasingly disinterested in social media like Facebook and Twitter. I figure if I’m going to note something down that looks like it might be useful to others I’ll put it on ye olde blog instead.
I’m sure the conversion isn’t perfect, and I’ve decided not to migrate very old content that simply not interesting any more (linux kernel patches from 2004 for example). If you find a post which has converted badly, just comment on it and I’ll do something about it. I am very sure that pretty much no one will do that thing however.
