I'd like to do the equivalent of the following in LINQ, but I can't figure out how:
IEnumerable<Item> items = GetItems();
items.ForEach(i => i.DoStuff());
What is the real syntax?
I would like to install an Apache server into a folder like c:\anything\???\anything2\ under windows.
When I try to start the service it sais that:
httpd: Syntax error on line xx of C:/anything/\xe6\x80\x98\xe6\x80\x99\e6\80\9a/anything2/apache/conf/httpd.conf: ServerRoot must be a valid directory
Does anyone have a solution?
Among the C-syntax family of languages (C, C++, Java, C#, ObjC, JS, AS, ...), which have a preprocessor compatible (to whatever extent) with the C preprocessor?
I want to add an additional value into an array before passing it to json_encode function,
but I can't get the syntax right.
$result = db_query($query);
// $row is a database query result resource
while ($row = db_fetch_object($result)) {
$stack[] = $row;
// I am trying to 'inject' array element here
$stack[]['x'] = "test";
}
echo json_encode($stack);
I have the following dictionary:
sites = {
'stackoverflow': 1,
'superuser': 2,
'meta': 3,
'serverfault': 4,
'mathoverflow': 5
}
To check if there are more than one key available in the above dictionary, I will do something like:
'stackoverflow' in sites and 'serverfault' in sites
The above is maintainable with only 2 key lookups. Is there a better way to handle checking a large number of keys in a very big dictionary?
I could do an endless timer checking IsInetOffline(), but I would prefer a hook callback that tells me when I plug/unplug the ethernet network cable or connect to wireless internet. Is there such a thing in the Windows API?
I have a python script that'll be checking a queue and performing an action on each item:
# checkqueue.py
while True:
check_queue()
do_something()
How do I write a bash script that will check if it's running, and if not, start it. Roughly the following pseudo code (or maybe it should do something like ps | grep?):
# keepalivescript.sh
if processidfile exists:
if processid is running:
exit, all ok
run checkqueue.py
write processid to processidfile
I'll call that from a crontab:
# crontab
*/5 * * * * /path/to/keepalivescript.sh
Thanks in advance.
What am I doing wrong here?

Guys,
I was hoping that someone can shed some light on why I am getting this error:
Parse error: syntax error, unexpected '{' in /homepages/22/d223624283/htdocs/drupal_new/includes/install.core.inc on line 74
Could it be something that I missed as far as D& configurations?
Thanks,
Matt
I am looking for the syntax to add node fields to the body of an email. Examples I looked at indicate the the format is:
[content_type:content_type_title]
However my email arrives with just the string :
[content_type:content_type_title]
Even better would be a PHP snippet that loads the node and dumps filed title and filed value into the body of the message.
I've checked out the man pages and did some searching but can't find info on ways to have rsync skip files greater than a certain size. We're doing rsync to an offline location and when someone puts a hug video file, the rsync jobs run into work hours.
I've looked at the 'exclude' syntax and didn't see anything for excluding based on file size.
Can I do it with rsync or should I look for other offline synching alternatives?
I hear a lot of Emacs users have their init file under git version control and sync the git repository over Dropbox, when they run Emacs on multiple systems.
Why would you use git in this situation exactly?
Usually checking which system you're on and which things to load and set depending on that can happen in one and the same init file for all systems, right?
So, isn't it simply enough to put your init file in a Dropbox directory and load that one directly from Emacs then?
I'm doing a bit more statistical analysis on some things lately, and I'm curious if there are any programming languages that are particularly good for this purpose. I know about R, but I'd kind of prefer something a bit more general-purpose (or is R pretty general-purpose?).
What suggestions do you guys have? Are there any languages out there whose syntax/semantics are particularly oriented towards this? Or are there any languages that have exceptionally good libraries?
I am in need of some help with trying to figure out how to go about checking the users session and seeing if they are still logged in or not.
The problem being is because i have a static page that pretty much loads everything into "tabs" using jquery. So when the user navigates the page, it really never leaves that same page they started out on. Hints my problem in trying to determine if they are still logged in or not when they click on update their information on their profile or whatnot.
i have one image background of table with following syntax

I'm having trouble with the following collections initalization:
private Dictionary<string, string> mydictionary = new Dictionary<string, string>()
{
{"key", "value"}
, {"key2", "value2"}
, {"key3", "value3"}
};
I keep getting various compiler errors about the syntax. From what I have googled this should be perfectly valid C# 3.0 code.
The first error that pops up is:
Error 102 ; expecte
What am I doing wrong?
Im trying to think of the best way to handle real time search for a website. The only solution I can come up with is to keep checking the server every few seconds for something new in the database, but that does not seem very practical to me.
I want to use case in sql statement where clause but I have a problem as I want to create a where clause condition on the basis of some value and I want to set a not in clause values on the basis of it
here is the query where am facing an issue
WHERE CODE = 'x' and
ID not in (
case
when 'app'='A' then '570','592'
when 'Q' then ID 592,90
else 592,90
END
but its not syntax
we have a situation where we log visits and visitors on page hits and bots are clogging up our database. We can't use captcha or other techniques like that because this is before we even ask for human input, basically we are logging page hits and we would like to only log page hits by humans.
Is there a list of known bot IP out there? Does checking known bot user-agents work?
I need to get counts to populate charts in Silverlight 4 and I am having a bit of trouble getting data back from my Domain Service mostly because I am not sure how to use aggregate query syntax. Has anyone had any luck populating charts in Silverlight 4 using aggregate (SUM, COUNT, etc) linq queries?
I am looking for any tool or good solution for handling spell check in the RichTextBox for Silverlight 4. Does anyone know of an existing solution or a good way to implement spell checking support for this control?
