I need your suggestions for the following. I am still learning RoR and
pardon my ignorance.

students addresses based on their id, is the only option is to get the
id from students controller method list

Running scripts in hadoop
R-help group,
I'm looking for some assistance on using an R-script to read STDIN from
hadoop.
Example, say I have two tables. One is a student table, the other is a class
roster table (tables join on student_id). Student SAT score is in the
student table, whether the student passed or not is in the roster table.
So to determine if a student passed or failed based on their SAT score, I'd

names separated by a space, or the student id number into a single search

Prioritizing VOIP traffic without sacrificing throughput
Hi,
I would like to prioritize VOIP traffic when we use the phone, but other
times not do traffic shaping at all.
Right now I have my openwrt router set up with htb to do shaping. In
order to get it to work well I had to set my upload and download speeds
much lower than my line speed. With these settings, I get good VOIP
reception even while surfing the net and doing a long download.
However,

Flattening a list of data frames
Hello all,
Simple version of my problem:
I've got a list of data frames, where each data frame has the same
number of columns and the same column names. I'd like to flatten the
list into one large data frame. Is there an easy way to do this?
Quick example code:
a <- data.frame(x=c(1,2,3),y=c(5,7,9)
b <- data.frame(x=c(2,4,7,9),y=c(2,3,5,4))
z <- list(a,b)

An object that initializes multiple objects?
Hi,
Something that I have noticed is that every class that inherits from
ActiveRecord::Base has a database table of its own.
However what if I don''t want a class to have its own table, but to
actually serve as a proxy to initialize other entries?
For instance as an example, let''s have a form with the fields for
"student name", "student id number",

[RFC PATCH 0/3] x86/paravirt: Get rid of paravirt patching
This is a small series getting rid of paravirt patching by switching
completely to alternative patching for the same functionality.
The basic idea is to add the capability to switch from indirect to
direct calls via a special alternative patching option.
This removes _some_ of the paravirt macro maze, but most of it needs
to stay due to the need of hiding the call instructions from the
