Development : The Cathedral & The Bazaar

Recently I had to explain to a none-developer how we had been working on a project, that is to say he and I.  I explained that our common boss worked very much in terms of the Cathedral, everything is big, grand, old, with set sources for supplies and almost dogmatic adherence to their ways of working.  Whilst he and I had been working, with extraordinary success, in a much more agile manner, in the manner of the Bazaar. Anyone could bring items to us, he could filter some queries, I could filter some others, between us we then worked in an Agile manner to achieve a result. I myself ran the development, and I pushed builds, lots of builds, releasing at least twice daily.  Any problem was picked up, worked on, solved and the next build had it, leaving a train of progressively better builds step by step, until we sit today with a fully functional system and we await input from multiple other sources. The main source for things we are awaiting is the Cathedral, we have ...

Server Admin : How Good is your Backup?

How robust is your back up solution?  Go on, be honest with yourself, how good is it?... Because I've seen a whole host of them and, at this very moment, this is the screen up on one of my servers.... Yes, my raid 5, just a test raid 5 with three really bad recycled SAS drives in it has failed; this doesn't surprise me, but it does delay me because I now have to rebuild the data... However, I know my data is good.... Lets see how good my back up is. This back up is coming from a DD created raw image of the virtual disk, stored to and soon lifted from my NFS accessible ZFS mirrored back up server. Therefore you would be right to ask, why are you rebuilding the virtual RAID disk in the above screen shot?  Well, I'm going to test my back up strategy! I popped the known bad disk and the good disks out, replaced all three and I'm able to test a restore to a new virtual disk set, I have a USB boot drive ready, this is a test. This kind of test, a real live restore, is sorely ...

Computing Education 2017

Here in the UK there have been several waves of trying to educate new generations as to the art of compute science, this started when I was a boy with the BBC Computer Literacy project and concluded soon after with a drought of interest from non-technical educators and politicians a like through until fairly recently. The BBC reports that there has been a low amount of uptake of new Computer Science GCSE studies. And I can believe this, however the neither the BBC nor government seems to even point as to why this is, they talk about pupil disengagement or lack of interest. I however contend that the government and educators and indeed the BBC completely fail to spot the elephant in the room, kids study not for jobs or skills, however they do study what is emphasised, IT has always been an "also ran" topic, it's not Maths, nor English nor seemingly as important in appearance as any other topic out there. In my day this was the case because few understood computing, today ...
