^ Ruby 1.8 vs 1.9
374232 [peter.pincus] how much longer will Ruby 1.8(.7) be maintained ? Is it advisable to
+ 374241 [cremes.devli] I believe the guys at EngineYard are in charge of backporting fixes to the 1.8.7 branch. I also heard there was a 1.8.8 coming at some point to be the final release in the 1.8 series.
| + 374242 [ryand-ruby z] would say the biggest reason to use it is to get a performance boost. =
| | + 374243 [phil pricom.] Who do I talk to get 1.9 RPMs produced for Fedora?
| | | + 374244 [ryand-ruby z] Beats me.
| | | | 374248 [aaron tender] My uncle Carl is really good at IT.
| | | + 374245 [cmdjackryan ] Just a guess: The Ruby (or Programming/Script language) maintainers of

| | + 374250 [cremes.devli] Definitely true. That's why I was careful to say "My code sees a 2-5x speedup..." because I have seen a few instances where 1.9 is a tad pokier. But clearly 1.9 is the future so sticking with 1.8 seems like a bad long-term bet.
| + 374260 [b.candler po] And just to give some balance: the biggest reason not to use 1.9 is
|   + 374263 [spam.entfern] Sounds great. ;-) Can somebody else confirm this?
|   | 374267 [m.fellinger ] iota ~ % echo =CA=98 | LC_ALL=3Dja_JP.UTF8 ruby -pe '$_[1,0] =3D "=CA=98"'
|   | 374269 [spam.entfern] So working with strings in ruby v1.9 is not supported, right?
|   + 374264 [m.fellinger ] And that's why I use and love 1.9.
|   | 374274 [b.candler po] Y'know, I wouldn't mind so much if it *always* raised an exception.
|   | 374278 [cmdjackryan ] Convert your strings to UTF-8 at all times, and you are done. You have

|   | | 374460 [drosihn gmai] to stay out of it these days. =A0However, his arguments always strike me as=
|   | + 374281 [b.candler po] But that basically is my point. In order to make your program

|   |   | 374293 [josh.cheek g] Its wrongness is an interpretation (I would also prefer that it just break,

|   |   | + 374310 [e148759 bsno] This is not even wrong.
|   |   |   374335 [cmdjackryan ] For certain values of "definitive", anyway.
|   |   |   374362 [yuri.tzara g] What psychological anomaly causes creationists keep saying that there
|   |   |   + 374364 [manuel kiess] Dear Yuri,
|   |   |   + 374365 [cmdjackryan ] I'm quite aware that IEEE 754 defines the result of x_0/0 as infinity.
|   |   |     + 374369 [spam.entfern] The point is that you can't guarantee that you has a 0 with floiting
|   |   |     | 374374 [cmdjackryan ] You can. In mathematics. The problem is, as you pointed out, that a 32
|   |   |     + 374373 [yuri.tzara g] Yes, it is. The creationist analogy continues, I see. Even when given
|   |   |       374376 [cmdjackryan ] "Unlike most mathematical models of the intuitive concept of 'number',
|   |   |       374383 [yuri.tzara g] Phillip, regarding defining 1/0 you said,

|   |   |       + 374386 [jos catnook.] This discussion has little to do with Ruby at this point. Maybe you folks
|   |   |       + 374414 [yuri.tzara g] The big picture is that IEEE floating point is solidly grounded in

|   |     | |   + 374388 [no spam.plea] To add to this, Unicode 3 uses the codespace from 0 to 0x10FFFF (not 0xFFFFFFFF),

|   |     | + 374356 [james grayso] I believe you are referring to the complaints the Asian cultures =
|   |     | | 374357 [shortcutter ] s raise against Unicode. =A0If so, I'll try to recap the issues, as I under=
|   |     | + 374366 [spam.entfern] Yes this is correct. Many people don't get the difference between a
|   |     |   374370 [shortcutter ] Btw, this happens all the time: for example, people often do not grasp
|   |     |   374389 [no spam.plea] ... on a particular relativistic trajectory ;-) Seriously though,
|   |     + 374457 [b.candler po] But that's not what Ruby does!.
|   + 374292 [ninja slapha] In 1.8, if those strings aren't in the same encoding, it will blindly=20
|     374313 [Ruby GoogleM] Actually, it's not. It's simply mathematically impossible, given that

|     | 374372 [Ruby GoogleM] .. and zero-width characters and different representations of the same
|     + 374394 [ninja slapha] Whoops, my mistake. I guess now I'm confused as to why they went with UTF-1=
|       + 374406 [cmdjackryan ] Because that's how the other applications written on the mainframe the

|       | 374444 [cmdjackryan ] You don't expect anyone to throw their older mainframes away, do you? ;)
|       | 374448 [ninja slapha] I suppose I expected people to be developing modern Linux apps that just
|       | 374452 [cmdjackryan ] Linux is usually not the OS the vendor supports. Keep in mind, a day
|       | 374462 [ninja slapha] In other words, you need someone who will support it, and maybe someone who=
|       | 374470 [cmdjackryan ] Both, and the Linux variant you use has to be certified by the
|       | 374472 [ninja slapha] Must be some specific legacy systems, because IBM does seem to be supporting,
|       | 374475 [cmdjackryan ] Oh, they do. But it's this specific Linux, and you get locked into it.
|       | 374488 [ninja slapha] When I hear "mainframe", I think of a combination of hardware and software
|       | 374490 [cmdjackryan ] Since it is, technically, a standardized language, with defined
|       | 374521 [ninja slapha] Sounds like we don't actually disagree.

|       | | 374629 [b.candler po] But rewriting COBOL in Perl may be a bad idea :-) Even rewriting it in
