For those of you in northern climes, here’s some tips on safer summer reading, and for once I have nothing to add. :)
As I had to throw together an example checklist for a course I’m running, here it is. I’ve also given a little bit of a commentary on the use, advantages and disadvantages of checklists as well. Enjoy. :)
There’s a very interesting site, run by a couple of Australian lads, called Text is Beautiful that provides some free tools that allow you to visually represent the relationships within a text. No this isn’t the same as Wordle, these guys have gone beyond that to develop what they call a Concept cloud, colours in the Concept Cloud are indicative of distinct themes and themes themselves represent rough groupings of related concepts. What’s a concept? Well a concept is made up of several words, with each concept having it’s own unique thesaurus that is statistically derived from the text.
So without further ado I took the Fundamentals of System Safety course that I teach and dropped it in the hopper, the results as you might guess are above. Very neat to look at and it also gives an interesting insight into how the concepts that the course teaches interrelate. Enjoy. :)
The DEF STAN 00-55 monster is back!!
That’s right, moves are afoot to reboot the cancelled UK MOD standard for software safety, DEF STAN 00-55. See the UK SCSC’s Event Diary for an opportunity to meet and greet the writers. They’ll have the standard up for an initial look on-line sometime in July as we well, so stay posted.
The final ATSB report, sloppy and flawed
The ATSB has released it’s final report into the Cleveland street overrun and it’s disappointing, at least when it comes to how and why a buffer stop that actually materially contributed to an overrun came to be installed at Cleveland street station. I wasn’t greatly impressed by their preliminary report and asked some questions of the ATSB at the time (their response was polite but not terribly forthcoming) so I decided to see what the final report was like before sitting in judgement.
The limits of rational-legal authority
One of the underlying and unquestioned aspects of modern western society is that the power of the state is derived from a rational-legal authority, that is in the Weberian sense of a purposive or instrumental rationality in pursuing some end. But what if it isn’t? What if the decisions of the state are more based on belief in how people ought to behave and how things ought to be rather than reality? What, in other words, if the lunatics really are running the asylum?
