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.
Hello,
I have written a webservice which is taking URL as an input and producing a JSON respone. My problem is that now I have list of 1000 URLs and want to execute maximum threads of Webapplications to get output. Like I want to execute 100 instances of webservice at a time to get response.Please can anybody give some guidance how can I do it using java.
Thank you in advance
Input integer array:
a[8] = { a1, a2, a3, a4, b1, b2, b3, b4 }
Output array:
a[8] = { a1, b1, a2, b2, a3, b3, a4, b4 }
Forget all corner cases, make sure your solution works for any int array of size 2n. You can use one or two temp variables for looping or anything, but you shouldn't use any temp arrays/stacks/queues etc to store entire array or part of array.
I'm able to get answer in O(n*log n), but I'm looking for better solution.
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

Is there any efficient way in python to count the times an array of numbers is between certain intervals? the number of intervals i will be using may get quite large
like:
mylist = [4,4,1,18,2,15,6,14,2,16,2,17,12,3,12,4,15,5,17]
some function(mylist, startpoints):
# startpoints = [0,10,20]
count values in range [0,9]
count values in range [10-19]
output = [9,10]
I have an array of entries I would like to print.
Being arr the array, I used just to write:
puts arr
Then I needed to use the DOS format end-of-line: \r\n, so I wrote:
arr.each { |e| print "#{e}\r\n" }
This works correctly, but I would like to know if there is a way to specify what end-of-line format to use so that I could write something like:
$eol = "\r\n"
puts arr
UPDATE
I know that puts will use the correct line-endings depending on the platform it is run on, but I need this because I will write the output to a file.
I believe Adobe tools like CS5 have ways to output as an iPhone app, but what about a regular AS3 or Flex project? Are there any tools to auto-port, or AS3/Flex iPhone implementations out there?
Out of interest, how does the CS5 thing work? Is it a totally different code-path or something less drastic? For instance Flash supports Shapes and Timelines, etc... do they in fact provide an iPhone Flash runtime of some sort?
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 :-)
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'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,

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.
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.
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.
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'
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 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);
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?
Open App.Path & "\Folder\" & str(0) For Output
Seems to get a path not found however if directly before that I do
MsgBox App.Path & "\Folder\" & str(0)
It Provides the correct directory/filename that I want
and if I replace that string with the direct path in quotes it works fine however that won't be very good for other users of my app :( Anyone know why this doesn't work?
I am having string called '200_CFL_2010'. I wish to get the characters between _'s. I want the output as 'CFL'. I have to achieve it through SQL. Any idea please?
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.
Hello,
I am tryin to Replace the start of line with a "(". However when i use replace all i'm not able to do so.
For eg:
432425\n
4254645\n
w4546746\n
46457367\n
4765756\n
I want the output as using Replace All
So i use the ^ symbol with Regular Expression Selected and Replace All.
Using only Replace works fine.
(432425\n
(4254645\n
(w4546746\n
(46457367\n
(4765756\n
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.
If i have a function api that expects a 14 digit input and returns a 6 digit output. I basically define the input as a const char *. would that be the correct and safe thing to do?
also why would I not want to just do char * which I could but it seems more prudent to use const char * in that case especially since its an api that i am providing. so for different input values I generate 6 digit codes.
