Huge firefox CSS issues
Huge firefox CSS issues
I made the following site: http://like-minded.us
to view it you'll have to log in from http://like-minded.us/wp-admin with
the credentials
username: stackoverflow pw: hellothere
then you will be taken to the dashboard - try to go to like-minded while
logged in and you'll be able to view it. The thing basically doesn't
render on firefox, and there is a problem in Safari that appears like it
didn't load a script or hit an error. I would love help with making it
compatible for both, but I am currently focused on Mozilla. I can't seem
to figure out how to find out where the problems in CSS are, and which
ones are the main ones preventing the site from rendering. I also am not
sure if the problem is in CSS in the first place. Can anybody point me in
the right direction? Sorry if there are not enough details, I tried to
cover everything I could think of. The site displays perfectly in Chrome.

Upload multiple files with jquery and coldfusion cffile
Upload multiple files with jquery and coldfusion cffile
Not really a question... Just wanted to post this somewhere because I
couldnt find it elsewhere. Now that I've cobbled together a working demo I
thought i would share. This works equally well on Coldfusion and Railo
CFML servers.
The problem is that for CFML developers is that CFFILE doesn't work with
<input type="file" multiple> ... traditionally if you wanted to upload 3
files and use CFFILE on the back end you would have to include 3 separate
file inputs on your calling page.
Here is my solution shaved down for simplicity. It uses Jquery $.ajax to
make several calls to CFFILE and returns the results to a div on the
calling page. Im sure there is a better way to do this and my code is
probably a complete hack but the below example works. Hope this helps
someone.

Can someone explain why f(n) + o(f(n)) = theta(f(n))?
Can someone explain why f(n) + o(f(n)) = theta(f(n))?
According to this page:
http://math.stackexchange.com/questions/195935/proof-that-a-function-plus-a-lower-growth-function-is-theta-the-first-function
The statement: f(n) + o(f(n)) = theta(f(n)) appears to be true. Where: o =
little-O, theta = big theta
This does not make intuitive sense to me. We know that o(f(n)) grows
asymptotically faster than f(n). How, then could it be upper bounded by
f(n) as is implied by big theta?
Here is a counter-example:
let f(n) = n, o(f(n)) = n^2. n + n^2 is NOT in theta(n)
It seems to me that the answer in the previously linked stackexchange
answer is wrong. Specifically, the statement below seems as if the poster
is confusing little-o with little-omega.
Since g(n) is o(f(n)), we know that for each ϵ>0 there is an
nϵ such that |g(n)|<ϵ|f(n)| whenever n¡Ýnϵ
Thank you.

Major differences between mod_fastcgi and mod_proxy_fcgi
Major differences between mod_fastcgi and mod_proxy_fcgi
I noticed there are a couple of modules for Apache that provide FastCGI
support. The two most popular seem to be mod_fastcgi and mod_proxy_fcgi.
There seem to be other ones as well.
My questions are:
Which of these module are the most popular?
Which of them are considered obsolete.
The reason I am asking is that I'm writing FastCGI support for a certain
scripting language and I wonder which setups I should primarily test with.
Granted, FastCGI is a standard so, in theory everything should be
portable. On the other hand, there seem to be certain differences
concerning application server start-up, etc. I would also like to write
some "how-to's" once I'm finished, so I would like to know which options
to cover primarily.
Hope this is not an open-ended question.

2 calculations with one populate button
2 calculations with one populate button
I have a simple worksheet that auto populates hours based on key values.
This all works fine. The problem I have now is that I need to add some
form of a contingency column which is a percentage figure of the total
hours used up to this column. Add the contingency figures to the sheet and
carry on with the populate.
Is there anyway i can do the first populate up to the contingency column.
Stop. Get the current value (for total hours) then do some calculations
and then carry on with the auto populate?
I don't really have any code I can share, but any pointers in the right
direction would be extremely useful.
Thankyou for your time.

Why is Internet traffic being blocked for .NET programs ONLY?
Why is Internet traffic being blocked for .NET programs ONLY?
We have a POS-based application in Windows Forms written in VB.NET, which
we're rolling out to franchise stores - 70, so far.
The application replicates data by means of a connection to a head office
server: all communication is by means of Web Services (upload & download).
All is working really well, except - you knew it was coming - on literally
a handful of stores we cannot connect to the web services, although we
know that the Internet service is good!
Here's a bullet-point summary of the situation:
in this handful of stores, ALL .NET (only) internet traffic fails on this
POS computer.
primarily this traffic is using port 80 to connect to web services, using
SOAP (standard)
BUT they can successfully use a browser in the POS to see web pages; also,
a test program I created in Clarion (straight Win 32) also connects to the
web service ok.
In addition, an associated data conversion app (again in VB.NET) also
fails when trying to connect to MS SQL at HQ (and only for this handful of
stores). Note: this uses a standard ADO connection, thus a completely
different protocol to the above.
So it's just all .NET Internet that fails... different apps, different
protocol. The error message in all cases is "The operation has timed out"
Note: timeout is set to 15 seconds - ample time for simple web service,
esp. as the initial method is just a time-check.
Take a POS that's failing to connect and move to a different site: all good
Take a POS that's failing to connect and change the router: all good
But the routers in failing stores are not all the same
It looks as if the .NET setup on the POS pc is somehow being 'blocked'.
Too weird - what am I missing here?
Grateful for pointers... I'm stumped! Steve.

Grateful for pointers... I'm stumped! Steve.
Google Chrome Extensions as standalone application
Google Chrome Extensions as standalone application
Is it possible to run a Google Chrome extensions outside of Chrome? For
instance, there is an add-on called TLDR which summarizes text on a web
page. Is it possible to write a program that can somehow "tap" into it's
summarization capabilities?

How to load a column generated by awk into a python list
How to load a column generated by awk into a python list
With awk it is very easy to extract a column of data in the bash terminal
using.
awk '{print $1}'
I am doing this inside a python script where i use a bash sequence to
extract the data i'm interested in
os.system(" qstat | awk '{print $1}' ")
If i call this in a certain context I get a column of numbers. I would
like to load all of those numbers into a python list. Can this be done
easily?

How do I approach this program?
How do I approach this program?
I need to fill in the code for this program. It is supposed to read
integer scores from a file and print out their average. We are supposed to
account for files that do not contain any integer values. The output is
just a simple print line displaying the averaged out scores.
he gives us a hint:"if input is a Scanner object associated with a file,
input.hasNextInt() returns true if there is an integer value left unread
in the file; otherwise it returns false."
import java.io.*;
import java.util.Scanner;
public class GradeAvg
{
public static void main(String[] args)
{
Scanner input = null;
double average=0.0;
try
{
input = new Scanner(new File("scores.dat"));
}
catch (FileNotFoundException e)
{
System.out.println("*** Can't open scores.dat ***");
System.exit(1);
}
System.out.println("The average of the test scores in the file are: ");
}
}

Turn off vibration inside my app
Turn off vibration inside my app
I'm developing an app and need to completely turn off vibration alerts
when my app is running. For example if an call comes in while my app is
open I don't want to have the vibration alert, the same with emails and
anyother notification.
So I've been googling around for a while and found this:
AudioManager amanager=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
amanager.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER,AudioManager.VIBRATE_SETTING_OFF);
The problem is that this method is deprecated. And I can't find an other
way of doing this.
The minSdkVersion = 9 and targetSdkVersion = 17.
Any idea?
Thanks!!
