Decoding Unicode URLs Properly
Please help,
I have an application I switched over to UTF-8, but I am unable to
decode URLs with unicode characters in them properly. For instance, if
I have "item=Pur%E9ed" as a parameter in my url, when it''s decoded by
rails, it returns "Pur?ed" and not "Pur?ed".
Is there an easy way to fix my controller to accept these characters
properly?

'nls' and its arguments
Dear R experts!
I'd to fit data by 'nls' with me-supplied function 'fcn'.
1) I'd like 'fcn' to accept arbitrary arguments, i.e. I defined it
as f(...) {<body>}. (Ok, that's not actually impotant).
2) Second, I would NOT like to supply every parameter in the formula.
To illustrate this, let's look at the last example of 'nls' help

How to eliminate for next loops in this script
I needed to compute a complicated cross tabulation to show weighted means
and standard deviations and the only method I could get that worked uses a
series of nested for next loops. I know that there must be a better way to
do so, but could use some assistance pointing the way.
Here is my working, but inefficient script:
library(Hmisc)
rm(list=ls())
load('NHTS.Rdata')

update.formula and backticked colons
I just noticed the following in update.formula and I'm wondering if
this behavior is the intention of the developers. Here's an example:
update(`a: b` ~ x, ~ . + y)
Note now that the response has no backticks and is interpreted as a:b
(i.e. ":" is now an operator). This is because in update.formula the
call to terms.formula uses simplify = TRUE. I'm working with data that

Backtick Hickup
I'm using Michel Fortin's MDTest cases to rewrite my html2text.php script.
Just now I stumbled upon this bug (in PHP Markdown at least):
# Input:
Backtick: ``\```
# Output:
<p>Backtick: `````</p>
# Should-Be Output:
<p>Backtick: <code>`</code></p>
If you (Michel) are already aware of this, just ignore me ;-)

Lazy Samba (that'd make it Waltz)
Funny thing happening with an NT Client: it sees all the files in a
public Samba share, but when I make any change (like renaming a file or
dropping files into it) the change doesn't show up in the window until I
press F5 (Refresh). Is it some config in Samba whichs defaults to "lazy"
behavior which I'm failing to see?
Thanx 4All,

Can't get simple link_to_remote to work
AFAICT, this is all I need to do to get a simple example working:
the <head> should have this:
<%= javascript_include_tag :defaults %>
My test page view should have a div with an id and the ERB like this:
<%= link_to_remote ''Click Me'',
:url => {:action => ''show_time'',
:update => ''time_box''} %>

Talking to Java APIs
I''m trying to figure out how Ruby in general, and/or anything extra
Rails may have, can talk to Java APIs of third party server apps.
After quite a few search attempts net-wide and on ruby forums, and
with "Programming Ruby" in hand, I''m coming up with zilch. Either I''m
not finding it, or I''m not recognizing it.
I''m assuming there has

backticks
I noticed just now that
package.skeleton() produces R files in which
the function names are escaped with backticks.
?Quotes says that "The preferred quote is the backtick (`)",
but I don't understand _why_ this is preferred.
?formula gives some clues but points out that there
are no guarantees that formulae using non-syntactic names such as
`like this` will be accepted.

Newbie: undefined method (backtick)body(quote) equals error
I have set up a simple test of a questionnaire; I have a set of
questions which have a many to many relationship with a set of possible
responses. I have it working so a user can set the range of responses
for a given question, but when trying any of the CRUD operations on the
responses side, I get a cryptic error, to which I see no reference to
online.
Thanks for any tips that may clear

How show validation errors in form_remote_tag?
I suspect this has been asked 400 times, but Google yields 2-3 rather
complex gymnastics in blogs (and possibly dated), and searching list
archives on ruby-forum proves kinda useless.
Using standard forms, it''s fairly easy to use
@object.errors[:field_name] in the form to embed an error message right
next to the field that has the invalid entry. The controller uses a
simple conditional

Escaping inside code blocks?
I am doing unit-tests for Maruku and every once in a while I run into
some doubts.
I am posting a lot to the list, but all of these messages should be
in-topic (tell me if not).
Consider the input:
---
`There is a literal backtick (\`) here.`
`There is a literal backtick (\\`) here.`
``There is a literal backtick (`) here.``
---
The documentation says that line 2 and 3 are equivalent.

Robust nonlinear regression - sin(x)/x?
You reall have only one parameter in your model, c = a/b. You can't
identify both a and b from your model, therefore, you should fit the
linear model: lm(z ~ c* sin(x)/x)

R 3.5.0 fails its regression test suite on Linux/x86_64
Hi,
I just tried to upgrade Nixpkgs to R 3.5.0, but unfortunately the new
version fails its regression test suite. We configure the build using
the flags "--without-recommended-packages", in case that's relevant. You
can see a complete build log with all relevant information at [1].
Anyway, the test failures look like this:

Strange: Repeatedly lose domain functionality
Hello All
Since several weeks, we face a very strange problem with a samba pdc and ldapsam.
It repeatedly seems to loose its pdc functionality. This brings very strange behaviours.
The server is then already accessable (shares and browsing works as expected),
but the windows machines cannot make a domain logon anymore (has then a priori no effect because
they use their cached password),

Markup for commands
Hi,
I just edited http://wiki.centos.org/de/TipsAndTricks/BecomingRoot and
formatted all the commands in section 1.1 as `monospace`. Since the main
font and the monospace font look quite similar, it is sometimes
difficult to see where one ends and the other starts.
Therefore I propose to add the following CSS rule to the whole CentOS wiki:
#page tt.backtick {
background-color: #eee;
