I am generally a big fan of Julien’s work and I’m very excited for the future of OpenStack Ceilometer of which he is the current PTL. However, in this case I think his views are understandably biased towards review workflows on very large projects like OpenStack, and I found the length of the rant slightly disproportionate to the actual substance of the points made within it. Somewhat ironically, AFAICS his blog’s own review process could use some improvement due to comments currently being disabled 😉 So here are my thoughts.
Disclaimer: currently I use GitHub for reviews more regularly than Gerrit, so my views are likely to be biased at least as much as Julien’s, but in the opposite direction 😉
UPDATE 26/02/2013: Daniel has replied to this post, and I have replied to his reply.
As George Santayana famously said, “those who cannot remember the past are condemned to repeat it”. In light of recent news regarding music notation software, I would add with some disappointment and frustration that those who choose to ignore the past are also condemned to repeat it.
For those of you who don’t already know, Sibelius is a proprietary software product for music notation which has for many years been one of the most popular choices for professional musicians and composers. For many of the more experienced customers in the technology industry who have already been burned in the past, a heavy reliance on a single technology is enough to trigger alarm bells – what if the company providing that technology goes bust, or decides to change direction and cease work on it, or simply does an awful job (*cough* Microsoft *cough*) of maintaining and supporting that technology? Then you’re up a certain creek without the proverbial paddle.
In the IT industry, this is a well-known phenomenon called vendor lock-in. A powerful movement based on Free Software was born in the early eighties to free computer users from this lock-in, and is now used on billions of devices world-wide. You may have never heard of Free Software, but if you own an Android phone or a “broadband” router, or have ever used the Firefox browser or Google Chrome, you have already used it. The vast majority of the largest companies in the world all run Free Software in their datacentres around the world; for example, every time you access Google or Facebook you are (indirectly) using Free Software.
In the summer of 2011, I quit my job to resume full-time music studies. During the summer semester at the Berkeley Jazzschool in California, I started learning John Coltrane’s solo on the title track of his famous album Blue Train. It was really tough going, but addictive – I was getting my arse handed to me on a plate on a daily basis by a dead person, but I felt like I was way off the well-trodden path and that was really satisfying!
Sometime later, I discovered a John McLaughlin video on YouTube (sadly no longer available) which had an awesome animated transcription at the bottom – a really cool glimpse inside the craft of a master musician. Then it occurred to me that I could do the same kind of thing with my video, and publish it in case there are any other jazz cellists out there who would be interested in it. I put a lot of effort into notating and fingering it, so it seemed a waste to just let it rot and never see the light of day. After all, I already had the source files and a video, so it was just a simple matter of combining the two, right? How hard could it be?
Very very hard, it turns out. I had to write two new pieces of software, completely overhaul a third, and fix some obscure bugs hidden deep inside a fourth. But I didn’t discover that until I’d reached the point of no return …
I’ll probably blog more at some point about the software engineering hoops I had to jump through in order to make this all work. Email me if you’re interested.
In the mean time, hope you enjoy the video! (You can also view it on YouTube.)
It continually astonishes me how often I see facebook status updates / group invites / tweets / emails from friends and acquaintances saying something to the effect of “ARGH my iPhone / Blackberry / Nokia phone has been stolen / lost / eaten by my pet donkey and I lost everyone’s numbers, please can you all send me your numbers!!”
People, it’s 2011 already! Whilst technology is still far from perfect, it landed a man on the moon 42 years ago way before mobile phones existed, and certainly solved this particular problem of disappearing phones several years ago.  So for those of you who still haven’t figured this out, without further ado I will outline a solution which should only cost 10 minutes of your life and ensure you never have to broadcast a panicked message cursing your pet donkey and asking everyone to send you their numbers.
Ouch. Arrived back home to a nice letter from Orange:
Great news. Every year we invite an exclusive group of customers to join our Premier Service for 12 months – and this year you’re one of them.
It went on to offer me a dedicated customer services and a USB dongle providing 3 months’ free mobile broadband, then 2p per MB after that. Amazingly generous, no? Then I realised why they’re being so nice to me:
