This blog is 10

Mon 02 July 2018 by Jim Purbrick

Just over ten years ago I set up The Creation Engine No. 2 after previously blogging on the original Linden Lab hosted Creation Engine and before that on Terra Nova. So, while I’ve been blogging for almost 14 years, 10 years of The Creation Engine No. 2 seems like a good excuse to look back at the last decade of blogging.

Behind the scenes the technology behind The Creation Engine No. 2 has changed a lot. Originally hosted as a Django site on Byteflow, I converted the blog to a static site generated by Pelican and hosted by github almost exactly 5 years ago. I wrote a post at the time detailing the move, which I finally published on its 5th birthday after rediscovering it today. Despite the big changes behind the scenes, github’s support for custom domains and Pelican’s support for RSS import meant that the only externally visible changes to The Creation Engine No. 2 were cosmetic. All the RSS feeds and links to the site were unaffected, which is great because Cool URIs don’t change.

While the technology has changed a lot, the content continues to mostly be a hack diary describing the various contributions I’ve made to projects like the EVE CREST API, nailgun, buck, infer and ReactVR. I write these posts as documentation in case I have to solve similar problems in future, but it’s also great when they’re useful to others, so I’m very happy to see that my recent set of posts about using ReactVR with Redux have been my most popular posts to date.

I don’t attend as many conferences now as I did while I was working at Linden Lab, but the various conference write up posts serve a similar purpose: reminding me about the talks and speakers I’ve seen and hopefully also pointing others to useful information. Social media is now more effective for letting people know about future events, so I rarely use The Creation Engine to announce upcoming events, but still think its a useful place to collect longform thoughts about past events and links to recordings.

One post which doesn’t fit in to the above catatories is my review of Now We Are 40 and thoughts on growing up with the web. Part of the reason I posted it here is because I could. I don’t need someone to speak for me or my generation, I can do it myself. I’m very grateful that I’ve been able to share my thoughts with the world for the last decade and very happy that a lot of people have found them useful.

Happy birthday to The Creation Engine No. 2. Here’s to the next 10.


Replicated Redux: The Movie

The recording of my recent React Europe talk about Replicated Redux is now online and I’ve written several other posts describing designing, testing and generalising the library if you would like to ...

Replaying Replicated Redux

Fri 10 November 2017 by Jim Purbrick

While property based tests proved to be a powerful tool for finding and fixing problems with ReactVR pairs, the limitations of the simplistic clientPredictionConstistenty mechanism remained.

It’s easy to think of applications where one order of a sequence of actions is valid, but another order is invalid. Imagine an ...

Building Safety in to Social VR

Thu 26 October 2017 by Jim Purbrick

Last year I hosted a panel on creating a safe environment for people in VR with Tony Sheng and Darshan Shankar at OC3. I commented at the time that the discussion reminded me of the story of LambdaMOO becoming a self-governing community told by Julian Dibbell in My Tiny Life ...

Testing Replicated Redux

Mon 31 July 2017 by Jim Purbrick

Opening a couple of browser windows and clicking around was more than sufficient for testing the initial version of ReactVR pairs. Implementing a simple middleware to log actions took advantage of the Redux approach of reifying events to allow a glance at the console to reveal precisely which sequence of ...

ReactVR Redux Revisited

Tue 04 July 2017 by Jim Purbrick

There were a couple of aspects of my previous experiments building networked ReactVR experiences with Redux that were unsatisfactory: there wasn’t a clean separation between the application logic and network code and, while the example exploited idempotency to reduce latency for some actions, actions which could generate conflicts used ...

2² Decades

Thu 20 April 2017 by Jim Purbrick

Several years ago when we were in 100 robots together, Max was celebrating his 40th birthday. When I said that mine would be in 2017, it felt like an impossibly far future date, but, after what feels like the blink of an eye, here we are.

Along with many other ...

VR Redux

Wed 04 January 2017 by Jim Purbrick

Mike and I have been talking about how to easily build simple networked social applications with ReactVR for a while, so I spent some time hacking over the Christmas break to see if I could build a ReactVR version of the pairs game in Oculus Rooms. Pairs is simple and ...

Creating A Safe Environment For People In VR

Mon 31 October 2016 by Jim Purbrick

I was very happy that Oculus found time at OC3 to host a panel on creating a safe environment for people in VR. As social VR becomes more popular over the next few years it will quickly have to learn how to keep people safe together in shared environments. Some ...

At the 3rd Party Dev State of the Union at EVE Fanfest 2016 earlier this year, CCP FoxFour drew my attention to a limitation of the current approach used by crestmatic to generate CREST documentation: it only discovers resources always reachable from the API root from the perspective of the ...

Strange Tales From Other Worlds

Tue 10 May 2016 by Jim Purbrick

At the end of last year, Michael Brunton-Spall and Jon Topper asked me if I would like to give the opening keynote at Scale Summit as I had “lots of experience scaling weird things”, by which they meant Second Life and EVE Online. I immediately thought of The Corn Field ...

Towards A Generic Media Type System

Sun 17 April 2016 by Jim Purbrick

The early days of RESTful hypermedia API design tends to involve lots of homogeneous collections. In the case of CREST vnd.ccp.eve.Api-v1 pointed to the logged in vnd.ccp.eve.ccp.Capsuleer-v1 which pointed to a vnd.eve.ccp.CharacterCollection-v1 of contacts which pointed to many vnd.ccp ...

I love record shops. Whenever I had pocket money it would go on Metallica and Nirvana CDs bought from Our Price or black t-shirts to match. When I lived in Nottingham I bought Boards Of Canada CDs from the same Selectadisc that my Dad bought a rare Fairport Convention single ...

crestmatic

Sun 03 January 2016 by Jim Purbrick

A year ago I gave a talk at EVE Vegas about building RESTful CREST applications. My #1 recommendation was to specify representations in requests, but that’s hard to do when there is little documentation on which representations are available and what they contain.

Fortunately CREST is self describing: send ...

Free Tests For Everyone!

Thu 11 June 2015 by Jim Purbrick

Modern software development is sometimes colourfully described as being similar to firing tracer bullets at a target. Rather than spending time doing a lot of research, design and specification up front, the smallest, simplest version of the software is built and the feedback gathered from its use is used to ...

Investing In Testing

Droidcon London

Last year I was talking to an engineer at Droidcon London who was working on an Android app with 100% test coverage. I immediately asked whether he thought 100% test coverage was worthwhile: many software engineering teams strive to achieve 100% test coverage, but few succeed because it’s an ...

As well as being fast, Buck gains a lot of power and flexibility by ...

Organisational Structures

Thu 20 March 2014 by Jim Purbrick

There have been a number of blog posts recently about exciting new organisational structures. As Cory points out “Every early stage company thinks it has reinvented management”: a very dangerous belief when betting on a new organisational structure can be much riskier than betting on the wrong product.

It starts ...
