Condic" strongly typed: >It looks interesting. Does this mean that development on AdaOS is ramping >up? I'm not sure about "ramping up"! Maybe stepping up a gear. I can only hope that as people see the vast technical superiority (and I'm not being ironic, for once) of AdaOS, they will be attracted. But that will surely be a slow process for the next few years. >Here's one thing I think is an excellent hook: The fact that you are >aiming to make it a distributed system. ... That's something kind of unique. Yes, I think it is. I am not very familiar with Andrew, but my impression is that in fact no-one has produced a truly distributed OS yet (that can shuffle processes between workstations arbitrarily, without any major restrictions). >Perhaps the more it aims at distribution and load balancing the more of a >niche it will find in industry. If it makes scaling up a system easy by >just plugging in more inexpensive computers, it could really catch on. I believe AdaOS really will make it easy to just add on computers. But this is not the only potential hook. It seems AdaOS may be the first general OS to offer proper security facilities (TCSEC B1 or B2). Do any others offer full dual labelling? >Especially to the extent that it can exploit Ada tasking as a distribution >mechanism ... I'm glad you have seen that point. I think it is a very significant one. There is currently a hot market in Internet servers, for e-business and many other purposes. These still all work on software that is very primitive (e.g. vulnerable to buffer overrun vulnerabilities), and I see this as one potential ouvre for AdaOS. >BTW: What theme is driving the naming scheme? Some of the names are old, and have simply stuck. For example, the program named "Avarus" (Latin for "miser") was named long before it became the object system manager, and was instead responsible for storage compaction. Some are new, and I have endeavoured to choose names that are original but which have some relevance. "Bachar" is the Gaelic for "acorn", which seemed appropriate for a microkernel. "Belenus" was a Celtic god of light and fire (and he was also associated with the forge and metalworking), and so seemed quite appropriate for a windowing program. "Carrot" is the name of a character, from the Discworld series of books by Terry Pratchett, who is phenomenal at remembering people's names (quite unlike myself ;-). Suggestions for program names are always welcome! -- Nick Roberts
