I want to define a function replicate to replicate a list of numbers by its value using only list comprehension, for example:
replicate [5,1,3,2,8,1,2]
output: [5,5,5,5,5,1,3,3,3,2,2,8,8,8,8,8,8,8,8,1,2,2]
I know this would be easy to use the 'replicate' built in function but only list comprehension is allow, how can I do this?
THANKS!

Hi! I'm using MySQL with PHP. This is like my table: (I'm using 3 values, but there are more)
id | 1 | 2 | 3
1 | 3 |12 |-29
2 | 5 |8 |8
3 | 99|7 |NULL
I need to get the greatest value in a certain row. If should get: (id - output) (1 - 2), (2-2), (3-1). Is there any queries for this? I've been trying, but I can't get it to work right.

Hi,
I have a javascript function that writes the value of input box to a cookie, then it tells the page to refresh. The page must be refreshed to the server side can reconstruct the page based on the values of the cookies. Output the correct data on the page.
However I do not want the user to lose the value they type on the input box unless they erase it.
what can i do?
(Context: running autohotkey scripts to try and automate some tests. The plan is to take screenshots and then compare them to 'standard' screenshots to detect if output has changed).
Is there a 'clever' way to check if two png images are different?
By clever I mean other than comparing them byte by byte? (after having compared their size, obviously)
I have a string which is converted from date to string and the data looks like this "6/2/2010 4:30:00 PM6/2/2010 4:45:00 PM" and I need output like this 04:30PM could u pls help.. thanx :-)
I am trying to subtract one variable from another, and use that output. but when I subtract them, the outcome is just the second variable negative!
int distance = pointX-pointXTwo;
NSLog(@"%d", distance);
Anytime I use 'script table as' - 'Insert To' (or other command), the script generated automatically places the database name in the script. Such as:
INSERT INTO [DatabaseName].[dbo].[tblToBeInserted] ...
While not a huge problem to just delete it, it has slipped by a few times and the script breaks if run on a different server with a different database name but has the same schema. (Such as running on [DatabaseName.Test])
Is there an option I can change, or can I modify the output in any way to remove this?
I have written an R script that pulls some data from a database, performs several operations on it and post the output to a new database.
I would like this script to run every day at a specific time but I can not find any way to do this effectively.
Can anyone recommend a resource I could look at to solve this issue? I am running this script on a Windows machine.
Using Java have the source code of a webpage stored in a string. I want to extract all the urls in the source code and output them. I am awful with regex and the like and have no idea how to even approach this. Any help would be greatly appreciated.
I'm trying to pass in both the field and the value in a find call:
@employee = Employee.find(:all,
:conditions => [ '? = ?', params[:key], params[:value].to_i)
The output is
SELECT * FROM `employees` WHERE ('is_manager' = 1)
Which returns no results, however when I try this directly in mysqsl using the same call without the '' around is_manager, it works fine. How do I convert my params[:key] value to a symbol so that the resulting SQL call looks like:
SELECT * FROM `employees` WHERE (is_manager = 1)
Thanks,

var Dog = function() {
var _instance = 'hello world';
return function() {
console.log(this._instance);
}
} (); //note that it is self invoking function
var l = new Dog(); //#> undefined
In the above case I was expecting output of 'hello world'.
Why this._instance is not accessing the the varible which should be accessible by virtue of closure. I tested this in FF and am getting undefined.
Hi!
I want to create a small code in C++ with the same functionality as "tail-f": watch for new lines in a text file and show them in the standard output.
The idea is to have a thread that monitors the file
Is there an easy way to do it without opening and closing the file each time?
In a perl script, I'm trying to accept input without blocking and without echoing the characters entered (The script is producing output and I want to have 'hotkeys' to alter its behaviour).
I got as far as using
use Term::ReadKey;
ReadMode( "cbreak", STDIN );
if($input = ReadKey($pause_time, STDIN)){
#process input
}
But once the user types anything then the script stops until a newline is entered. I'd like the input to be processed per-character, without waiting for a newline.
Hello guys, anyone know how to get the age based on a date(birthdate)
im thinking of something like this
string age = DateTime.Now.GetAccurateAge();
and the output will be some thing like 20Years 5Months 20Days
How can I access the first value from
object t = (object) wsf.LinEst(y.ToArray(), x.ToArray(), false, true);
The output is
object[1..5, 1..2]}
[1, 1]: 0.17134831460674155
[1, 2]: 0.0
[2, 1]: 0.019612696690686725
[2, 2]: -2146826246
[3, 1]: 0.95020429009193053
[3, 2]: 0.82746057986828336
[4, 1]: 76.328205128205056
[4, 2]: 4.0
[5, 1]: 52.261235955056179
[5, 2]: 2.7387640449438226
I need to get only [1,1] 's value i.e. 0.17134831460674155
How to get that.
The linEst return an object only.
I am using C#3.0
Thanks

I have a log file that is constantly growing, how can I watch and parse it via a ruby script. The script will parse each new line as it is written to the file and output something to the screen when the new line contains the string 'ERROR'
I'd like for my app to be able to tell if an image hasn't been viewed in the last 30 days and remove it (along with data in the DB associated with it). I know you can have PHP read and output the image dynamically but I've heard its quite taxing on the system. Is there a way to for me to track these hits even when the image is viewed directly? (would htaccess be able to do this?) Thanks in advance.
I have a large data file that is creatd from a shell script. Next script processes it by sorting and reading several times, that takes more than 14 hours, it is not viable.
I want to replace this long running script with a program, probably in JAVA, C, or COBOl, that can run on windows or on sun solaris. I have to read a group of records everytime, sort and process and write to the output sort file and at the same time insert into db2/sql tables.
import os
dictionaryfile = "/root/john.txt"
pgpencryptedfile = "helloworld.txt.gpg"
array = open(dictionaryfile).readlines()
for x in array:
x = x.rstrip('\n')
newstring = "echo " + x + " | gpg --passphrase-fd 0 " + pgpencryptedfile
os.popen(newstring)
I need to create something inside the for loop that will read gpg's output. When gpg outputs this string gpg: WARNING: message was not integrity protected, I need the loop to close and print Success!
How can I do this, and what is the reasoning behind it?
Thanks Everyone!
