Re: how to use curly brackets vs. 'end' in Ruby

I certainly cannot disagree with that!

:-)

bad-hungarian is when you prefix a variable name with type information
eg:

  fWidth = fSize

the 'f' simply means float.  you can see you have type compatibilty on both
sides, but it doesn't say anything about semantic compatibility. fWidth
could be used as a measure in metres, whereas fSize is expressed in feet!

good-hungarian is when you prefix a variable name with semantic information

   metric_width = feet_size

you can see immediately that there is a problem there.  both variables are
of the same type (Float), yet they have a different meaning.

I would argue that in ruby -using duck typing- we use good hungarian quite a
lot.

So I got a binary file...

Sorry for being such a NEWB. I'm a pretty prolific PHP writer however 
I'm new to RUBY and want to expand my horizons.

I have a big-endian binary file and want to convert it to ascii so I see 
what's in it.
Is there an easy way to accomplish this?

Thanks
Robert

Not sure what you mean.  Do you want an ASCII hex dump of the
file?  (like `od -x`)  Or just strip the binary characters, and print any
ASCII sequences found (like `strings`) ?

I think you may have mis-understood my question (or I didn't explain
properly), what I was asking was more a design question than a general "I'm
building yet another editor what do you think" question. As you took the
time to write a response I'll answer you though (check bottom where I
re-phase my query):

Both, I'm very interested in editors and find myself downloading new ones as
they arrive and playing with them (though I'm an avid Vim user).

Well, the idea is to write the base of the editor in C and have the API
almost completely available to Ruby. So, theoretically, it could be as
full-featured as Emacs or as simple as Notepad. ;)

Amen to that.

What's "new" in drb?

What's "new" in distributed Ruby? And by "new" I mean
less than five years old.   ;)

Possible Bug in mysql-ruby 2.7


I am trying to store very small gzipped files in my mysql database. The storage works great, but when I
retreive the data some
fields are interpolated.

  Examples:
      \010  becomes \007
      \012  becomes \032

There may be others, but those are what I have noticed thus far. I am using the Mysql.quote method to store my
data. I am runnng:
  ruby 1.8.4 (2005-12-24) [i486-linux]
  mysql 5.0.20-1
  mysql-ruby 2.7

Thanks,

Zach

This does not appear to be a bug in mysql-ruby... appears to be some of my code...

Well, I don't know anything about Python and not a whole heck of a lot
about Ruby. I've been using Perl for fairly complex "scripts" for almost
ten years now. Like another poster on this thread, I got tired of trying
to manage large "awk" scripts and wanted a language that made it at
least possible to write structured readable programs. That turned out to
be Perl 4.

If I were starting this project or set of projects today, I'd use Ruby.
It's much better designed for objects than what's been tacked on to
Perl. I don't have any pressing need to rewrite my few thousand lines of
Perl into Ruby (or Python), and what I don't do in Perl is usually
number crunching that I do in R.

So questions for you:

1. Do you just want to learn a new language, or is there something
