The man page of epoll_ctl() says about EPOLLPRI:
There is urgent data available for
read(2) operations.
How exactly is "urgent data" defined and who decides which data has priority?
What characters are allowed in linux environment variable names? My cursory search of man pages and the web did only produce information about how to work with variables, but not which names are allowed.
I have a Java program that requires an defined environment variable containing a dot, like com.example.fancyproperty. With Windows I can set that variable, but I had no luck setting it in linux (tried in SuSE and Ubuntu). Is that variable name even allowed?
I've been trying to do SEO friendly urls, and managed to get it work, but when I call index action on blogs, I get a weird "undefined method `parameterize' for nil:NilClass." The method works when using show method.
def to_s
title
end
def to_param
"#{id}-#{to_s.parameterize}"
end
What are cons if we do not care about validation of XHTML and CSS?
In terms of development time,
Code debugging,
Cross browser compatibility,
website maintainability,
Future changes in website,
SEO ranking
Accessibility (Does validity increase
accessibility)
I have to explain a client that Code validation is not just Fashion, it is beneficial for his site.
I would like to create a predicate to search for a specific letter at the start of each word in a string of words e.g. all words starting with A in @"The man ate apples", would return ate and apples. Is it possible to create such a predicate? Thank you.
If I make a simple diff in git with e.g.:
git diff origin/master
where can I find good references on how to read the output of git. The man page on git-diff is rather long, and explains many cases which are maybe not necessary for a start.
I'm looking for cheap SSL certs for running a personal website over https without triggering Firefox's "you may be facing a man-in-the-middle-attack" response that self signed certs provoke. Nothing particularly fancy, no EV, etc. Any recommendations/where do you get your certificates from?
i saw this phrase in python 2.6 man:
class threading.Thread(group=None, target=None, name=None, args=(), kwargs={})
.
.
.
If the subclass overrides the constructor, it must make sure to invoke the base class constructor (Thread.__init__()) before doing anything else to the thread.
i just wanna know why?
In Solaris, gcc gives me
implicit declaration of function `getopt'
when compiling
#include <unistd.h>
#include <stdlib.h>
int main(int argc, char *argv[]) {
getopt(1,argv,"");
return 0;
}
The man page for getopt says something about including unistd.h or stdio.h, however even though I'm inluding both I still get this warning. Is this normal? Is using functions that aren't explicitly declared common in Unix development?
HI,
I used to have PHP websites and using url rewriting on picture to have SEO friendly urls,
On php I had links like
/image/blablablabla-1234-blablabla
rewriting to:
/image/1234.jpg
by using a url rewrite rule on apache .htaccess file.
Now I totally switched to ruby on rails and I would like to know what is the best way to do that on RoR? I am hosting websites on apache with passenger.
Thanks in advance
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?
We are going to publish API documentation on our web site.
The documentation is generated by Doxygen from sources.
The problem is that Doxygen generate weird file names (which is no so good for SEO).
For example, for source file RO4_Languages.h Doxygen generate _r_o4___languages_8h.htm.
Is it possible to change name of generated files?
PS: I know that it possible to change output using 3rd party tools/scripts (awk/sed/perl/etc).

I had to compile a small little C program using the following;
gcc sine.c -o sine -lm
I needed the "-lm" because the program included the math.h.
In looking this up under compiler commands man shows it a either -llibrary or -l library.
I could not find any information on what other libraries. Apparently -lm is needed for math.h
what other library commands might be needed.
Thanks
GNU xargs has option '-x'. The man page says:
-x Exit if the size (see the -s option) is exceeded.
But xargs seems to not care if -x is set or not. I have been unable to make an example in which the -x has any effect at all.
Please provide two examples in which the only difference is an added -x and that produce different output.
We use a fucking ridiculous amount of goddamn bandwith man. It really pisses me off because now I have to fucking upgrade my goddamn account and my site doesn't make jack shit for money.
So how the fuck can I automatically reduce the whitespace and shit? I'm GZipping the output already.
I need to add one parameter to the default REST route for the show action for SEO purposes:
resources :neighborhoods, :only => [:index, :show]
neighborhood_url(neighborhood) # => /neighborhoods/lower-east-side
I want something like the following:
neighborhood_url(city, neighborhood) # => /neighborhoods/manhattan/lower-east-side
What would be the easiest way to do this without using nested routes and without breaking Rails REST conventions?
Question: epoll man page has some pointers when using epoll with an 'event cache'. But, why would you need to maintain an event cahce at all - Isn't this the same as what epoll is supposed to be doing?
Is it to avoid making multiple epoll_wait calls which might be slower than managing the events in user space?
Is it to implement a custom 'priority' scheme over the cached events?
Background: I'm trying to understand the strengths/shortcomings of epoll and its applicability to different situations
The man says that case statements use "filename expansion pattern matching".
I usually want to have short names for some parameters, so I go:
case $1 in
req|reqs|requirements) TASK="Functional Requirements";;
met|meet|meetings) TASK="Meetings with the client";;
esac
logTimeSpentIn "$TASK"
I tried patterns like "req*" or "me{e,}t" which I understand would expand correctly to match those values in the context of filename expansion, but it doesn't work.
Thanks.
I have some code that I am porting from an SGI system using the MIPS compiler. It has functions that are declared to have double return type. If the function can't find the right double, those functions return "NULL"
The intel C compiler does not like this, but I was trying to see if there is a compiler option to enable this "feature" so that I can compile without changing code. I checked the man page, and can't seem to find it.
Thanks
What is the best tested way to hide any text from sighted user but not from popular screen readers?
and without affecting SEO.
for example if i adding any hidden text only for screen-reader users then that text should not be crawl by search engine when search engine will crawl that page.
I have an existing domain which has some hosting, I recently purchased a new domain which is for a seperate site. Is it possible to host my new site in a subfolder on the existing hosting? I know you can use web forwarding but doesn't that have negative SEO implications?
I'm converting some URLs from a web application using ASP.NET 4.0 friendly SEO Urls:
From
<a href="profile.aspx" ></a>
To
<a href="<%= Page.GetRouteUrl("Profile", null) %>" ></a>
The problem is before conversion when I try to hit profile.aspx it would fire the application_authenticaterequest but after conversion when I try to hit Page.GetRouteUrl it would not fire the application_authenticaterequest.
Thanks
