Komodo doesn't "own" the code written with it. It's just an IDE!

These kinds of restrictions are(IMO) silly to the point of counterproductive -- we want people to beproductive programmers and have no fear using our tools, we don't wantto own your work!> Avoiding lock-in needn't prevent a software company from gaining> revenue from the sale-value of their software; a time-deleyed oepn> source license allows both criteria to sit comfortably.

However, I think it's important to note a key difference-- Komodo is not necessary for doing anything. It's not like Komodo isa key piece of IT infrastructure which you (the customer) would ever bein a position to rely on to the point of being locked in. This is(again, speaking for myself) the key factor which drives whether whatActiveState does is Open Source or not -- technology which is 'keyinfrastructure' should be Open Source because it lets people andcompanies build the systems they want to build with no lock-in. HencePyXPCOM is Open Source -- we think it's really really cool technology,and we're proud of it, and it cost us a fair bit of money to develop,but we think it belongs in the 'key IT technology' category, so we don'ttry to extract revenue from it. The same need is not as present fortechnologies and products which simply make people more productive, makea process more efficient, or otherwise 'enhance' a process orprocedure. We think it fair to get some revenue from the latter. It isalways up to the customer to decide whether the benefit is worth thecost.Cheers,--David AscherPS: If people have concerns about corporate licensing policies, theyshould feel free to express them, of course. Typically, however, suchfeedback is more likely to be effective if it's directed to thecompanies directly instead of posted on a newsgroup. Now, I have noproblem with having this particular discussion out in the open [*], butI can assure you that companies react more favorably to constructiveemails sent to the appropriate people than to what some perceive as'attacks' out in the public. It's just how companies operate, forbetter or worse.[*] I do have a very small issue with conversations about ancienttheories of cognitive science going under the heading "ActiveState goingthe wrong way", but that's Usenet and I live with it =).PS: My own take on the recall/storage/reading/lookup/encoding/memorytopic is that after getting a PhD in cognitive science and seeingtheories come and go and reading through dozens of experimental reportsand suffering through my fair share of experiments, I'll stick withConan Doyle, William James, and the like. They wrote much better thanmodern scientists typically do, and their intuitions are much moreentertaining than most data. =)PPS: Andrew, you should mine James for quotations if you haven'talready. My PhD advisor has an collection, although I don't think he'sindexed it. See for example "The Principles of Psychology" nicelyavailable at:http://www.emory.edu/EDUCATION/mfp/james.html. The manfigured out most of cognitve science and cognitive neuroscience ahundred years ago =).
