How can I display the content of a folder after some time of its creation, in order to see the newly added files? Any script with File.readlines? any help? James Gray wrote: On Mar 1, 2006, at 1:43 PM, misiek wrote: I can not find nothing about files in google, how to create"m... 30 Jul 2010 09:40

Compiling Ruby through JRuby?
Hi! I'm currently building a program which will be mostly standalone, and use little libraries, if at all. If I want to use the project as a library within a Java program, would it be possible to compile it through JRuby? -- Thank you for your brain. -MrZombie ... 4 Aug 2010 01:42
leak tracking x64
Have easily reproducable memory leaks, need to find them. I'm running Ruby 1.8.6 on an windows7 x64 machine. I checked out memprof, bleak_house et al. I can't find anything compatible with my architecture / ruby version and prefer not to patch VM. would it be worthwhile trying to walk the GC or is there some... 4 Aug 2010 01:42
.any?{} Behavior
David A. Black wrote: As I see it, all? and any? make sense in terms of each other. If array.all? is true for a condition, that means that array.any? is false for the opposite of the condition: array.all? {|e| cond(e) } == !(array.any? {|e| !cond(e) }) I think that always holds.

binary encode 7 ([7].pack("C")) as "\007" instead of "\a"

.all?{} and [].any?{} Behavior
The docs pretty clear... If the block is not given, Ruby adds an implicit block of{|obj| obj} (that is all? <Enumerable.html#M003131>  will return true only if none of the collection members are false or nil.) Its an assumption is always true unless the block tells it something different.. Assuimng Happy unle... 1 Aug 2010 08:19
[].all?{} and [].any?{} Behavior
I find the following behavior interesting (so interesting that I modified it), and I would like to hear others' thoughts on the subject: [3].all? {|element| element == 3 } # => true [3].all? {|element| element != 3 } # => false (sanity checks) [].all? {|element| element == 3 } # => true [].all? {|element| ... 29 Jul 2010 18:29
Problem with a lambda not executing immediately
Hi, I'm using the paperclip plugin for one of my rails app, but my problem is pure Ruby. I'm not good enough with Ruby and lambdas so I need your advice.
