I just spent several hours catching up on the last week. I hadn't finished, but I decided to publish anyway, and was just proof-reading it all before sending it in. I was only part way through when I left for a few minutes for a snack. When I got back I had a very attractive screen telling me that I had to reboot. I've rarely seen this on my Mac before, and on each occasion the notebook was extremely hot to touch. Perhaps a chip failed through heat? There's not a lot than an operating system can do about that.
So I've just lost a couple of thousand words. I'm a little frustrated. I haven't experienced this in years, as modern applications regularly save their position. However, the proliferation of web interfaces has led to a reversion in technology. I'm now thinking that I should do all of my editing in a text pad (that will auto save) and just use a web browser at the last moment in order to publish.
Hmm, maybe I should learn Firefox, just so I can put in a patch that will autosave text fields (particularly large ones), and re-load them on the next execution. The file can then be deleted as soon as a page is submitted.
On the other hand, I have so much to do at the moment, learning a new system just doesn't seem like an option.
Just so I don't forget, the things I wrote about were:
- The problems with determining OWL cardinality in the open world model, with consideration given to
- Speculation on some specific cases with
- Difficulties in performing the subtraction operation, including some suggestions for making it possible to compare different
- The problems where
sort(Tuples)does not skip the operation when sorting is needed. This needs to be fixed, and when it is the join and subtract operations will both be improved.
I also need to write about bugs with variable predicates in the transitive function, the new insert/select bug, and a proposal for a simple open source semantic extractor (an important component that seems to be missing in the open source world - why is that?)
Anyway, I've been at this for hours, and I need a break. I'll work on it later.
