Same thing that happens if you ping 127.1 or 127.0.0.1 or 12.1 or 0xc.1 or 0x7c.0xf1 or ... ping translates it as x.0.0.y and runs the query. I would say that this is a bug in ping, that it would allow x.y to be evaluated as a complete ip address. But what is going on is that ping is calculating the address based on the first and last dot numbers and fills in the blanks with zeros. if you want the RFC explanation for it, I'd have to look it up. I don'ty keep that kind of trivia in my head, hell I have a hard enough time keeping in the important stuff. ;') Brian D. __________________________________________________ Do You Yahoo!?

Does not make it not a bug. I still consider it a bug. Here's my reasoning, if a program does an interpretation of the user input that the user might not have intended then ... it might be a bug. If a program behaves in an irrational way to input then ... it might be a bug. If a program fills in missing information then ... it might be a bug. It's certainly a nice little l33t trick for those in the know to use for short-cutting, etc. But, it's still is translating what might have been an accidental <CR>. I might want to ping 12.1.0.5, but if my hand slips and I hit return after 12.1 or 12.1.0 then I wind up pinging the wrong address (12.0.0.1 or 12.1.0.0). But even bugs have uses, whether they are intentional or not. ;') Thanks for the trivia, Gerald. Brian D. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

RE: database
by Leo Mauler 04 May '05

Another question regarding databases. I'd prefer using ANSI SQL or even SQLite, but the issue has come up that the local newspaper managers might want the database output into Microsoft Access. Is that easier to convert from Access to SQL or easier from SQL to Access? (I think I know the answer, I just want to hear it from someone who does this professionally) Also, is it easier (or better for that matter) to use an SQL database when putting it on the Internet? In other words, if I'm forced into Access should I create a side copy in SQL just for the Web? --- Leo Mauler <webgiant(a)yahoo.com> wrote: > Here's an interesting question: if one uses SQLite > and suddenly needs MySQL or something else more > complex than SQLite, how complex will the > conversion be? > > --- "Timothy A.

Yes, it was a script first and book later, as far as I know. The first 2 episodes didn't have to be boring, he let them be. What is next in the Dune series after Children of Dune?

Not sure why, but try pinging 127.1 does the samething, 7f is 127 so adding .1 just makes it work. Weird though. Seems like 127.1.*.* are all able to be pinged and get a response from 127.0.0.1.

The learning curve for MySQL is going to be probably not much more than SQLite (I also haven't seen SQLite). Plus, if you ever need to do some powerful SQL stuff or ever want to play around with doing powerful SQL stuff, then you'll just be able to do them with MySQL. If you go with SQLite, and then you need to do some tricky types of stuff with the data, you'll probably have to port everything over to another DB. From what I understand of SQLite, that is. I hear it is sort of like MySQL in the early days. Lastly, with MySQL you'll be garaunteed to be able to speak to any important database.

Just noticed it when I was reading messages, that now I've got a 1GB mail storage limit. I'm only using 2% of it, but its a big change anyway. :) __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
