Thank goodness all three will still be able to participate.

Sometimes in this free-speech forum people bring up secondary points. This one was relevant only insofar as it addressed how someone chose to communicate in a post to a Java discussion forum. Had the post been to a C# forum it would have been less relevant to a Java discussion. Much as Roedy will encourage people to avoid the lazy and, to him, offensive use of "wanna" for "want to", I sometimes find lazy, stupid and questionable English usage grating. This does not apply to those doing their best to express themselves in a foreign language, but simple things like spelling "Java" correctly, or spelling "you" instead of "u" or "because" instead of "cuz" just represent a habit of diligence and completeness that spills over into code. If someone is too lazy and illiterate to spell "because" or risk misunderstanding because "cuz" really abbreviates for "cousin", then perhaps they are careless with Javadocs, or logging, or unit tests, or covering all possible inputs to a method. OTOH, in the OP's case I am quite sure it was not laziness or stupidity, but I thought the facts about the word were interesting enough to post. Furthermore, I anticipated that mentioning those facts would stimulate discussion and give me the opportunity to put in a pitch for professionalism and a habit of diligence. -- Lew

Don't get all sanctimonious with me. It looked suspiciously to me like an off-topic criticism of another poster, and its motive was therefore probably pretty base. > I sometimes find lazy, stupid and questionable English usage grating. Fine. But it's not the topic of this newsgroup, and on at least some points of English usage, opinions are liable to differ. > If someone is too lazy and illiterate to spell "because" or risk > misunderstanding because "cuz" really abbreviates for "cousin", then > perhaps they are careless with Javadocs, or logging, or unit tests, or > covering all possible inputs to a method. This seems like quite a stretch. Fine effort at rationalization, though, and at trying to shoehorn it in as tangentially on topic. :) > OTOH, in the OP's case I am quite sure it was not laziness or > stupidity, but I thought the facts about the word were interesting > enough to post. Furthermore, I anticipated that mentioning those facts > would stimulate discussion Well, that it certainly did -- off-topic discussion. Congratulations on lowering the SNR of this once-fine newsgroup slightly. :) Now I shall probably endeavor to avoid making it any worse by dropping this. Unless of course a particularly egregious response gets posted.

Like I've said elsewhere, the least fragile approach is to actually parse the string and re-create it. Regex hacks might work, but they might fail in unexpected ways. -- Daniel Pitts' Tech Blog: <http://virtualinfinity.net/wordpress/> |
