create an object from a string?
I''m trying to dynamically create an instance of an object at runtime, from a
String. I have a method that returns one of a number of Strings ("Car",
"Motorcycle", "Bicycle"), and when I receive the String, I then want to
instantiate one of those objects.
Seems like there should be a way to do it in Ruby, but maybe I''ve been up
too long -- can''t find it. In Java, I''d be doing something like this:

The result of this calculation is:

36.54109 36.54109 36.54109 36.54109
But this doesn't give the same result as the dplyr method which is:

samba4.2.0 crashes on connection attempt with an internal samba error...
...nstalled.
(maybe a better idea would be to copy it... it was my first
attempt with KVM, but it seems to work OK). I will keep notes
and report, on how I got it running (or failed to do so).
Best regards

PS: But first of all I am going to do a little tour with my bike

How is the overhead different whether your code checks it or Xapian does?

Rails 1.1.5: Mandatory security patch (and other tidbits)
.... We''ve made sure that Rails 1.1.5 is
fully drop-in compatible with 1.1.4. It only includes a handful of bug
fixes and no new features.
For the third time: This is not like "sure, I should be flossing my
teeth". This is "yes, I will wear my helmet as I try to go 100mph on a
motorcycle through downtown in rush hour". It''s not a suggestion, it''s
a prescription. So get to it!
As always, the trick is to do "gem install rails" and then either

Switching databases in Rails v1.0 app
Hello, I need some guidance. I have a need to:
a) Login, validating against a "system-level" user database - no big
deal, then
b) Depending upon the login, select a customer database for processing.
For instance, assume that my login profile lists an area of interest:
cars, motorcycles or boats. Each of these has a database, with identical
table formats. If my login shows my area of interest to be boats, then I
want to disconnect from the system-level database, and establish a
connection to the boats database. At this point in time only the
system-level database appears in t...
