If I make a list in Python and want to write a function that would return only odd numbers from a range 1 to x how would I do that?
For example, if I have list [1, 2, 3, 4] from 1 to 4 (4 ix my x), I want to return [1, 3].
Say you had a timestamp function and then wanted to create a new function to combine your timestamp and Console.WriteLine(), e.g.
public static void Write(string msg)
{
WriteTimeStamp();
Console.WriteLine( msg );
}
But the WriteLine() method has 18 or so overloads, which will not be reflected in the signature of the wrapper function. How would you have the wrapper take non-strings and pass them on to WriteLine()?
Is there anything like Beanshell, which exposes CLR classes instead of Java classes, and lets you write scripts in C# or VB.Net (or any .Net language for that matter)
Should come in handy to test one-liner code snippets
Hi Guys,
a bit of a naive question, but nonetheless. I am trying to break up a for loop in which a 2d Matrix is being read. I would like to write a callback function to consume row-wise/col-wise chunks per row/col iteration. Any hints on how to tie up the callback function with iteration?
Hello, This is quite probably a very silly question but I need to be sure. I've been given a class declaration in a header file eg.
#ifndef file_H
#define file_H
class ex{
private:
public:
};
#endif
and I've been required to write the method definitions in the same file, which I have done, my question is does the "#endif" stay where it is just after the class declaration or does it go at the end of my file after the class method definitions?.
Is this equivalent to a LEFT JOIN?
SELECT DISTINCT a.name, b.name
FROM tableA a,
(SELECT DISTINCT name FROM tableB) as b
It seems as though there is no link between the two tables.
Is there an easier / more efficient way to write this?
i have interest rate and amount in a table where interest rate are ranged in different values
like 4.5,4.6,5.2,5.6 etc.
i want to get sum of amounts classified by interest rate where interest rate will be separated
by .25.
for example all amount having interest rate 1.25,1.3,1.4 will be in one group
and 1.5,1.67,1.9 will be in another group
how can i write the query?
I've set up a view which combines all the data across several tables. Is there a way to write this so that only columns which contain non-null data are displayed, and those columns which contain all NULL values are not included?
I have a file containing the following content 1000 line in the following format:
abc def ghi gkl
how to write perl script to convert it into :
abc ghi
??
Is there anything wrong with the code? It's not working.
<script>
t=document.getElementById('good');
document.write(t.value);
</script>
HTML:
Type-here: <input id='good' type='text' value="my value is high">
I'm trying to write a function :
Input:
Source range, Source value, output range, curve type (Linear, smooth)
Output:
The output is the "source value" converted into the "output range"
according to the curve type.
I hope I am making sense here...
Any ideas ?
Thanks.

I've got some experience with Bash, which I don't mind, but now that I'm doing a lot of Windows development I'm needing to do basic stuff/write basic scripts using
the Windows command-line language. For some reason said language really irritates me, so I was considering learning Python and using that instead.
Is Python suitable for such things? Moving files around, creating scripts to do things like unzipping a backup and restoring a SQL database, etc.
I've got an image generator written in C. Now I want to pass those images to x264 to encode them and write it to a file.
Every 100th image should be a key frame in order to save the video to disk every 100th frame.
The image generator calls onImageGenerated() after each image.
I'd appreciate any pointers on how to set up x264 in this way.
Is there a simple way to invert a WPF GridView so that items are bound to columns instead of rows? Or would it be necessary to write a custom view mode?
There are more and more programming languages (Scala, Clojure,...) coming out that are made for the Java VM and are therefore compatible with the Java Byte-Code.
I'm beginning to ask myself: Why the Java VM?
What makes it so powerful or popular that there are new programming languages, which seem gaining popularity too, created for it?
Why don't they write a new VM for a new language?
I need to get all characters between '(' and ')' chars.
var str = "dfgdgdfg (aaa.bbb) sfd (c) fdsdfg ( ,ddd (eee) )";
In this example, I need to get 3 strings:
(aaa.bbb)
(c)
( ,ddd (eee) )
What pattern I have to write? Please, help.
I need to track the completion of tasks for users.
I started by having a row called "first_login", "profile_complete", "other_thing_complete", etc...
I'd like to combine these all into one row "activity_state".
I just don't know how to properly store data in this field, and how to retrieve it.
What kind of field should it be, and how should I read/write to it?
Models:
* Person
* Club
Relationships
* Membership
* Committee
People should be able to join a club (Membership)
People should be able to be on the board of a club (Committee)
For my application these involve vastly different features, so I would prefer not to use a flag to set (is_board_member) or similar.
I find myself wanting to write:
People
has_many :clubs :through = :membership # :as = :member? :foreign_key = :member_id?
has_many :clubs :through = :committee # as (above)
but I'm not really sure how to stitch this together
I am using codeigniter. I want to know how to set up a cron job to check a table for expiring users and insert data in to another table with the list of expiring users. How to do that.
When i tried to write a script with controller and model to insert the table
:
Content-type: text/html
Fatal error: Class 'Controller' not found in /home/content/html/test/live/application/controllers/cron.php on line 2
I have:
tXML = "<type p_type=\"All\"/>";
if I do
Response.Write(tXML);
I get a blank space.
Is there anyway to output this string so I know it is being created?
I asked a question earlier about ESBs written in Erlang or Java, and there didn't seem to be anything in Erlang, and only products in Java.
http://stackoverflow.com/questions/2453641/what-would-be-the-best-language-in-which-to-write-an-esb/2453683#2453683
I guess I find it difficult to understand why a language like Erlang has no such middleware products, especially seeing as it should be ideally suited to the job.
