I need to find the amount of updated rows
UPDATE Table SET value=2 WHERE value2=1
declare @aaa int
set @aaa = @@ROWCOUNT
It doesn't work. How can I do that?
In R, what is the most efficient way to count the length between 2 values. for example, i have vector x , which are all randomly choose from 1 to 100, how can i find out the length between the first"2" and first"40",
x=(1,2,3,4,5,6,7,40,1,2,3,21,4,1,23,4,43,23,4,12,3,43,5,36,3,45,12,31,3,4,23,41,23,5,53,45,3,7,6,36)
for this vector, the answer should be 5 and 6
The title explains it well. I have set up Notepad++ to open the python script in the command prompt when I press F8 but all Swedish characters looks messed up when opening in CMD but perfectly fine in e.g IDLE.
This simple example code:
#!/usr/bin/env python
#-*- coding: UTF-8 -*-
print "åäö"
Looks like this.
As you can see the output of the bath file I use to open Python in cmd below shows the characthers correctly but not the python script above it. How do i fic this?
I've just noticed when loading my client's page (http://habbopfm.com/) in Firefox, that it renders what looks like a rectangle is pushed down a few pixels.
It's difficult to describe, but imagine you took a screenshot of the page, opened it in Photoshop, selected a rectangle and moved it down a bit.
IE and Safari don't appear to do this - I'm assuming this is a browser glitch, not a problem with the code. Can anyone confirm what causes this?
Below is a screenshot taken of the issue:

One other thing is that it only does this once the page has finished loading. While it is loading, it looks fine.
I'm writing some C code to parse IEEE 802.11 frames, but I'm stuck trying to create a new variable whose length depends on the size of the frame itself.
Here's the code I currently have:
int frame_body_len = pkt_hdr->len - radio_hdr->len - wifi_hdr_len - 4;
u_char *frame_body = (u_char *) (packet + radio_hdr->len + wifi_hdr_len);
Basically, the frame consists of a header, a body, and a checksum at the end. I can calculate the length of the frame body by taking the length of the packet and subtracting the length of the two headers that appear before it (radio_hdr->len and wifi_hdr_len respectively), plus 4 bytes at the end for the checksum.
However, how can I create the frame_body variable without the trailing checksum? Right now, I'm initializing it with the contents of the packet starting at the position after the two headers, but is there some way to start at that position and end 4 bytes before the end of packet? packet is a pointer to a u_char, if it helps.
I'm a new C programmer, so any and all advice about my code you can give me would be much appreciated. Thanks!
This is just a hypothetical scenario to illustrate my question. Suppose that there are two threads and one TVar shared between them. In one thread there is an atomically block that reads the TVar and takes 10s to complete. In another thread is an atomically block that modifies the TVar every second. Will the first atomically block ever complete? Surely it will just keep going back to the beginning, because the log is in an inconsistent state?
I'm trying to replace a bunch of Linux shell scripts with Scala scripts.
One of the remaining challenges is how to scan an entire directory of JARs and place them into the classpath. Currently this is done in the shell script prior to invoking the scala JVM. I'd like to eliminate the shell script completely.
Is there an elegant scala idiom for this?
I have found this other question but in Java it seems hardly worthwhile to mess with it:

Suppose I have a span:
<span class="myspan"></span>
.myspan{
background: url(image.png) top left no-repeat;
}
How do I make it so that when people hover my span, it shows "image_hover.png"?
I'm trying to use Simple Savant within my application, to use SimpleDB
I currently have (for example)
public class Person
{
public Guid Id { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public DateTime DateOfBirth { get; set; }
}
To use this with Simple Savant, i'd have to put attributes above the class declaration, and property - [DomainName("Person")] above the class, and [ItemName] above the Id property.
I have all my entities in a seperate assembly.
I also have my Data access classes an a seperate assembly, and a class factory selects, based on config, the IRepository (in this case, IRepository
I want to be able to use my existing simple class - without having attributes on the properties etc..
In case I switch out of simple db, to something else - then I only need to create a different implementation of IRepository.
Should I create a "DTO" type class to map the two together?
Is there a better way?
MYMESSAGE = "<div>Hello</div><p></p>Hello"
send_mail("testing",MYMESSAGE,"[email protected]",['[email protected]'],fail_silently=False)
However, this message doesn't get the HTML mime type when it is sent. In my outlook, I see the code...
Hi all, would the following Jquery selector get all of the 4th td elements of all the tables on the current page, and return their text as an array?:
var isbn = $.makeArray($("table tr td:nth-child(4)").text());
I have a very big table with a lot of rows, every row has stats for every user for certain days. And obviously I don't have any stats for future. So to update the stats I use
UPDATE Stats SET Visits=@val WHERE ... a lot of conditions ... AND Date=@Today
But what if the row doesn't exist? I'd have to use
INSERT INTO Stats (...) VALUES (Visits=@val, ..., Date=@Today)
How can I check if the row exists or not? Is there any way different from doing the COUNT(*)?
If I fill the table with empty cells, it'd take hundreds of thousands of rows taking megabytes and storing no data.
I'm having problem loading a json resource from a local rails app with jQuery 1.4.4
The json is valid (based on jsonlint.com) and I can download it properly if I'm requesting it from other sources.
In webkit (Safari), I got this error:
Failed to load resource: cancelled
Response Header on Firebug:
Content-Type application/json; charset=utf-8
Set-Cookie geoloc=toulouse; path=/;
Connection close
Server thin 1.2.7 codename No Hup
jQuery code to load json:
$.getJSON("http://127.0.0.1/search_agenda",
{'edition': edition,
'categories': categories},
function(data){
console.log(data);
}
});
I am running my junit tests via ant and they are running substantially slower than via the IDE. My ant call is:
<junit fork="yes" forkmode="once" printsummary="off">
<classpath refid="test.classpath"/>
<formatter type="brief" usefile="false"/>
<batchtest todir="${test.results.dir}/xml">
<formatter type="xml"/>
<fileset dir="src" includes="**/*Test.java" />
</batchtest>
</junit>
The same test that runs in near instantaneously in my IDE (0.067s) takes 4.632s when run through Ant. In the past, I've been able to speed up test problems like this by using the junit fork parameter but this doesn't seem to be helping in this case. What properties or parameters can I look at to speed up these tests?
More info:
I am using the reported time from the IDE vs. the time that the junit task outputs. This is not the sum total time reported at the end of the ant run.
So, bizarrely, this problem has resolved itself. What could have caused this problem? The system runs on a local disk so that is not the problem.
I'd like to get the latest NHibernate build or build it by my own. The build available at SourceForge is dated by Nov 2009, although I see there was a lot of activity later, especially related to LINQ development.
So what is the best option? I can:
Get the latest source code and try to build it. Are there any instructions for this?
Get one of latest builds shared by someone else. Are there any people maintaining such builds?
Please note, that I'm not interested in 8-month old builds - I need the latest code for tests (LINQ, performance).
I know there is a similar question, but it looks like top answers there are outdated.
Suppose I have some output from a command (such as ls -1):
a
b
c
d
e
...
I want to apply a command (say echo) to each one, in turn. E.g.
echo a
echo b
echo c
echo d
echo e
...
What's the easiest way to do that in bash?

I've deployed a SSIS package to my SQL server.
I can run the package fine by connecting to Integration Services in SSMS and right clicking on it and choosing "Run Package"
However, if I schedule the package, it fails.
It tells me to check the logs for information on why, but there is nothing in there...
Any ideas?
(this is my first SSIS package by the way)
I know that the android plattform is open source. What I am interested in is the share of open source Android apps, thus developers that realease their own apps under a open source license.
Does anybody have an idea, how to get this information?
I am using the Kohana 3 framework, and am using the native session driver.
For some reason, occasionally the sessions fail to write to their file.
Warning: session_start() [function.session-start]: open(/tmp/sess_*****, O_RDWR) failed: Permission denied (13) in /home/site/public_html/system/classes/kohana/session/native.php on line 27
I am pretty sure Kohana has its own in built error handler, but it is not triggered with this error (i.e. it shows up like a normal PHP error, not the Kohana error).
Anyone that has ever used Kohana will notice this seems to have bypassed Kohana's error handling (perhaps set with set_error_handler()).
Is there anyway to stop this error from appearing without switching from the native session (i.e. file based) driver?
Should I just give good practice the boot and append an @ error suppressor to session_start() in the core code of Kohana? Should I relax the error_reporting()?
Thanks
