in R , when i use "print", i can see all the values, but how can i save this as a vector
for example, in for loop,
for (i in 1:10), i want the value of A , when i= 1,2,3,4..... but if i use the x=A, it only have the final value of A which is the value when i = 10. so , how can i save the vaule in print(A)
Hello there, I have a div with id kGrowl and inside that div I have a select element with name = mover. I try to use this selector:
$('#kGrowl:contains([name=mover])').length
But it is currently returning 0. How is my selector wrong?
Thanks.
Hello, is there a good regex expression that would be able to compare two dates
like 3/27/2010 to 3/8/2010 to tell if the first date is greater then the second date?
I'd like to compare using javascript
I've seen this all over the web
javascript:__doPostBack('ctl00$ContentPlaceHolder1$lnk2','')
Checking headers of the last place I saw it didn't reveal a server side language.
What server side language and/or framework encourages this style of link?

Greetings.
I am querying tables from Microsoft SQL 2008 which have date split across 3 columns: day, month and year. Unfortunately, I do not have control over this because data is coming in to the database daily from a 3rd party source in that format.
I need to add between to a where clause so user can pull records within a range. Would be easy enough if date was in a single column but finding it nearly impossible when its split across three columns.
To display the date, I am doing a
CAST(
CAST(year as varchar(4)) + '-' +
CAST(month as varchar(2)) + '-' +
CAST(day as varchar(2))
as date) AS "date"`
in a select. I tried to put it as a parameter for datediff function or just the regular between but get no results.
Thanks for any help.
Suppose I have this:
<select id="myselect">
<option rel="a">1</option>
<option rel="b">2</option>
<select>
How do I use JQuery so that onchange $("#myselect"), I alert the "rel" part of the option (not 1 or 2)
With a long but plain html document opened on a mobile device (webkit), how do I ensure that text doesn't crop vertically when scrolling?
I think this should be possible by either adjusting line spacing or adding extra padding.
TIA.
Hi Folks,
Trying to debug something that basically .trim()'s, .val()'s and .length's a textarea input as HTML below (truncated):
<form id="Kontaktanfrage" method="post" action="tests/testform/">
...
<textarea cols="50" rows="8" id="el_12" name="FORM[Kontaktanfrage][el_12]" title="Ihre Nachricht: *" class="textarea required"></textarea>
...
</form>
JavaScript:
function validateField(formId, fieldId) {
if (fieldId) {
var element = "form#"+formId+" input#"+fieldId;
var fieldValue = jQuery.trim(jQuery(element).val());
var fieldLength = fieldValue.length;
var fieldError = "";
if ($(element).is('.textarea.required') && fieldLength == 0) {
fieldError = "error message";
}
}
}
The above if check is never true.
Using JQuery: 1.4.1.
Having seen other examples online, I can't see what the difference should be. Feel free to test it in FireBug at (http://www.initiat.de/tests/testform/). Any help appreciated, can't see what I'm doing wrong.
I have a search engine that searches albums.
For each music album, I have a page.
So, the work flow goes like this:
People search for music titles
The search engine displays a list of albums.
People click on an album to go to a details page.
I want google to index my front page and the details page. I want the details page to be highly ranked. How can I build a sitemap for this?
By the way, I have about 5 million albums (but I want the top 1000 ones to be highly ranked on google)
I am writing an abstract matrix class (and some concrete subclasses) for use on very differing hardwares/architectures, etc. and I want to write a row and column type that provides a transparent reference to the rows and columns of the matrix.
However, I want to tune for performance, so I'd like this class to be essentially a compiler construct. In other words, I'm willing to sacrifice some dev time to making the overhead of these classes as small as possible.
I assume all (small) methods would want to be virtual? Keep the structure small? Any other suggestions?
I wonder if this possible with Zend_Db, but I am looking for something like SQL query logging similar to how Hibernate does it, where it shows you what SQL it generates in the log file.
Suppose I have a datetime column in MySQL.
How do I select all that have a datetime within 2500 seconds of the current datetime?
SELECT ALL where current_datetime - that_datetime < 2500 ...
sorry, im sure this is asked a bunch, but i couldnt find it.
in myModule.py:
from myModule.subModule import myClass
i am working on myClass, and want to stay in my ipython session and test it. reload(myModule) doesnt re-compile myClass.

I have noticed that the quality of the images produced by the JPEGEncoder does not match that of other encoders available (i.e. php's built in image compression functions from the gd library)
Any explanation ? or hints/workarounds for improving the quality of compressed images by JPEGEncoder ??
| random_code | varchar(200) | YES | UNI | NULL | |
MyTable.objects.filter(random_code = None)
Is this correct? Will this SELECT where there is no random code set? Above is my table.
d3 = dict(d1, **d2)
I understand that this merges the dictionary. But, is it unique? What if d1 has the same key as d2 but different value? I would like d1 and d2 to be merged, but d1 has priority if there is duplicate key.
I know there are many settings for a language for a table and a database.
I already created the database. I believe when I created it, it was default/LATIN. I want to change everything-I mean...both the table and the database, to UTF-8.
How can I do that? thanks.
Is there a simple :) and efficient way or reading very large number of rows sequentially using Zend_Db?
Basically I need to process entire table, row by row. Table is large, primary key sequence is not guaranteed(i.e. not an autoincrement, but is UNSIGNED INT).
What's the best way to approach this?
Environment: PHP 5.2, Zend Framework 1.10, MySQL 5.1
