Is there a Maven plugin to fetch an rpm
Is there a Maven plugin to fetch an rpm
Folks,
As part of my current procedure,I have to do a Linux package fetch,
followed by a Maven build.
Is there a Maven plugin to fetch a Linux package ( rpm -i xxx or apt-get
install xxx )
maven-exec-plugin enables this. but is there a more specialized plugin
that wraps data on top?
Note : - maven-rpm-plugin and maven-apt-plugin seem to allow you to create
rpm packages, not to fetch them
Thanks, - Ranjan

Can mysql import a csv or other txt file into one column?
Can mysql import a csv or other txt file into one column?
In mysql we can import data files -
load data infile 'file.txt'
into table `text`
fields terminated ' '
lines terminated '\n'
My question is can we import a file with unknown columns all into one
column? Or possibly can we create columns that we need on the fly?

Using a rails scope query in a controller
Using a rails scope query in a controller
I'm working on my first rails project, and I'm having trouble getting my
query to work correctly. My overall goal is to setup a collection of
scopes to create some long queries with multiple options. However, to
start with, I'm just trying to set up a single scope, to query a single
column from a single model. Here is my model:
class Drawing < ActiveRecord::Base
has_many :revisions
scope :by_description, lambda { |description| where(description:
description) unless description.nil? }
end
Here is the index action of my controller:
def index
@drawings = Drawing.by_description(params[:description]).all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @drawings }
end
end
And the view is the default index view for rails.
When I enter an input into the search field, for example "Case", the
submit button works and directs me to the index view, but all of the
"Drawings" are listed, instead of just the ones that have "Case" as their
description. Thanks so much for your help.

PHP Issue in Twitter API Caching Script
PHP Issue in Twitter API Caching Script
I admit I am a level below functional retardation when it comes to code
development of any sort. I'm trying to create a script that calls the
Twitter API and caches responses. I can call the API and get data without
issue, I can write it to a file too, and I can call the file to display
the info.
However, every time this piece of code is called, it results in a hit to
Twitter's API gateway. I can tell by reading the responses from a shell
window; this is on a busy site and I see the number of available
transactions decrease quickly when the script is made live.
Why isn't it delivering just info from the file, and running $tweets
everytime?

Golang/App Engine - securely hashing a user's password
I have typically used the bcrypt library to do password hashing, but am

java regex what the heck? am I misreading the regex docs completey?
java regex what the heck? am I misreading the regex docs completey?
System.out.println("a".matches("^[A-Za-z]+"));
System.out.println("a ".matches("^[A-Za-z]+"));
This gives me:
true
false
What the heck is up? As far as I am reading it, "[A-Za-z]" includes "a",
and "+" means one or more, so this seems like it would work, at least in
this universe....
Details are:
Mac OS X 10.8.4
$ java -version
java version "1.6.0_51"
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-457-11M4509)
Java HotSpot(TM) 64-Bit Server VM (build 20.51-b01-457, mixed mode)
Maybe I have been writing perl too long and java's regex system is kind of
like it but not? No idea.

Comparing strings to a dictionary in groups of multiples of 3
Comparing strings to a dictionary in groups of multiples of 3
I am writing a program which reads in a number of DNA characters (which is
always divisible by 3) and checks if they correspond to the same amino
acid. For example AAT and AAC both correspond to N so my program should
print "It's the same". It does this fine but i just don't know how to
compare 6/9/12/any multiple of 3 and see if the definitions are the same.
For example:
AAAAACAAG
AAAAACAAA
Should return me It's the same as they are both KNK.
This is my code:
sequence = {}
d = 0
for line in open('codon_amino.txt'):
pattern, character = line.split()
sequence[pattern] = character
a = input('Enter original DNA: ')
b = input('Enter patient DNA: ')
for i in range(len(a)):
if sequence[a] == sequence[b]:
d = d + 0
else:
d = d + 1
if d == 0:
print('It\'s the same')
else:
print('Mutated!')
And the structure of my codon_amino.txt is structured like:
AAA K
AAC N
AAG K
AAT N
ACA T
ACC T
ACG T
ACT T
How do i compare the DNA structures in patters of 3? I have it working for
strings which are 3 letters long but it returns an error for anything
more.
EDIT:
If i knew how to split a and b into a list which was in intervals of three
that might help so like:
a2 = a.split(SPLITINTOINTERVALSOFTHREE)
then i could easily use a for loop to iterate through them, but how do i
split them in the first place?

Is it possible to group Plone portlet fields into fieldsets?
Is it possible to group Plone portlet fields into fieldsets?
I have a very long portlet edit screen so I'd like to group its fields

Is this possible with zope.formlib?

Embedded YouTube videos without hidden controls until clicking on the video
Embedded YouTube videos without hidden controls until clicking on the video
I'd like to display embedded YouTube videos with the controls hidden by
default, and when the user clicks on the video, controls appear. Just as
the videos on this page.
In Google documentation pages I found how to hide controls altogether, but
not in this way. And using Firebug while visiting this page I can't see
any options used in the iframe code that relates to controls.
So how to do that?

Increase load test over time
Increase load test over time
I would like to test the load of my App Engine App.
From the load test google recommendation. Query per second should increase
gradually.
So I would like to add 1 connection every second to my load test. How can
I do that? I search for AB (Apache Benchmark) and JMeter without success.
Maybe my question is very basic, but as I'm not use to load testing I
don't google it properly.
Thanks.

Heroku RoR 3.2 ignoring http put request
Hello all I built a website with RoR 3.2 and hosted it for free on heroku
:)! This website receives http put request from client side applications
that update the database every 60 seconds. I am seeing an issue where the
first few(2-10) http put request come through to heroku just fine but then
they randomly stop. I have checked my client app and it is still sending
the http put requests but I no longer see them in the heroku logs of the
application. I was wondering if maybe heroku has doesn't like me sending
put request so frequently and is blocking me? Thanks for the help!

gets.chomp method excercise in learn to program book
gets.chomp method excercise in learn to program book
I'm new to programming/Ruby. I am doing excercise 5.6 out of "Learn to
Program" for a class. I have the following:
puts 'What\'s your first name?'
first = gets.chomp
puts 'What\'s your middle name?'
middle = gets.chomp
puts 'What\'s your last name?'
last = gets.chomp
puts 'Hello, Nice to meet you first middle last'
And I have tried the following:

first = gets.chomp
puts 'What is your middle name?'
middle = gets.chomp
puts 'What is your last name?'
last = gets.chomp
puts 'Hello, Nice to meet you #{first} #{middle} #{last}'
When I get the last "puts" it won't get the first, middle and last name
that I wrote in. It says, "Hello, nice to meet you first, middle,
last....Instead of Joe John Smith for example. What am I doing wrong?
Thank you so much for your help! I really appreciate it!

Boot-repair doesn't work
Boot-repair doesn't work
I am a new user, and I may have completely screwed up my computer trying
to install Ubuntu 13.04. I'm working from a liveUSB, and I'm pretty sure I
accidentally uninstalled Windows 8 (which is what my computer came with -
now the computer doesn't recognize any boot device without the USB
inserted), and now the computer simply won't boot. When I start the
computer with the liveUSB inserted, I am taken to a page headed "GNU GRUB
version 2.00-13ubuntu3", which allows me to select "Try Ubuntu without
installing" or "Install Ubuntu," and I've already installed it - if I try
to install again, it gives me the option of installing alongside Ubuntu
13.04 or replacing it, so I am pretty sure it installed the first time but
it just won't boot. I then used Try Ubuntu and followed the instructions
under 2nd Option on this page:
https://help.ubuntu.com/community/Boot-Repair
I tried rebooting, and it didn't work - I just went back to the "GNU GRUB
version 2.00-13ubuntu3" menu once again. The url from my boot-repair
attempt is http://paste.ubuntu.com/6030961
I know this is very chaotic, and I am in way over my head, so any
help/advice would be much appreciated!

How to include php-generated javascript?
How to include php-generated javascript?
I've looked around and have found no great solution so far: I would like
to add customized javascript from a widget using wp_enqueue_script, but
Wordpress seems to be limiting scope to the javascript file I load in, as
my javascript file says:
Uncaught TypeError: Object [object Object] has no method 'photogallery'
Here is the output I would like to load in, as if it were its own script
via wp_enqueue_script:
<script type = "text/javascript">
(function ($) {
"use strict";
$(function () {
var $gallery = $("#gallery").photogallery(
"a",
{
thumbs: <?php echo
setBool($instance["hasThumbs"]); ?>,
history: <?php echo
setBool($instance["historyEnabled"]); ?>,
time: <?php echo
($instance["transitionTime"] * 1000); ?>,
autoplay: <?php echo
setBool($instance["autoplayEnabled"]); ?>,
loop: <?php echo
setBool($instance["isLooped"]); ?>,
counter: <?php echo
setBool($instance["hasCounter"]); ?>,
zoomable: <?php echo
setBool($instance["zoomable"]); ?>,
hideFlash: <?php echo
setBool($instance["hideFlash"]); ?>
}
);
});
}(jQuery));
</script>
I know that manually coding the default values in to another js file, and
using enqueue_script will work fine, but how do I do this properly, with
custom widget values, and not load the required js file twice? I am not
interested in complex ajax requests unless it is my only option, as
mentioned here.
Thanks in advance.

What exactly defines a Main Loop and a Secondary Loop?
What exactly defines a Main Loop and a Secondary Loop?
My assumption is that the main loop is always the first loop and you're
always supposed to use query_post? Is this correct? Then whenever you you
need to feed in some arguments to get a different set or order of posts
you use WP_Query or get_posts. These would both be secondary loops? I just
feel I'm hardly interacting with the Main Loop at all so I have this
feeling, whilst everything works, I'm just not doing things properly.

JAVASCRIPT: OK button proceed to another .php form
JAVASCRIPT: OK button proceed to another .php form
I have a basic javascript code for my saving entry.
Scenario:
I have two forms, the first form,[view_netbldg.php], is for my data entry
then when the user click the "ADD" button it will proceed to the next form
[save_netbldg.php]. So in my save_netbldg.php form there is a if else
condition where the code will know first if the variable of $bldgName or
$netName are empty. Everything is okay, but my concern is this when the
code detect either of the two variables are empty the code below I'm using
will be executed.
Here's my code:
if($bldgName == "" || $netName == "")
{
echo "<script type='text/javascript'>\n";
echo "alert('Please complete the fields for Building Name or Network
Name');\n";
echo "</script>";
header("location:view_netbdlg.php");
}
*The result of the program is, its not displaying the alert instead it
will jump to the header
The correct way is, if the $bldgName == "" || $netName == "" == true** an
alert will display and when the user click the ok button it will proceed
to the next form which is "view_netbdlg.php". I don't need a confirmation
message here because its only an error message something like that.
Advance thank you.
I have a basic javascript code for my saving entry.
Scenario:
I have two forms, the first form,[view_netbldg.php], is for my data entry
then when the user click the "ADD" button it will proceed to the next form
[save_netbldg.php]. So in my save_netbldg.php form there is a if else
condition where the code will know first if the variable of $bldgName or
$netName are empty. Everything is okay, but my concern is this when the
code detect either of the two variables are empty the code below I'm using
will be executed.
Here's my code:
if($bldgName == "" || $netName == "")
{
echo "<script type='text/javascript'>\n";

what's the best library to display 3d stuff in C#?
Say I have an array of point coordinates in a 3d space, like
point1 x=5, y=10, z=15
point2 x=1, y=25, z=3
... and so on.
And I need to show them in a sort of a 3d environment, where the user
would be able to zoom in, pan and rotate, in a winform.
I haven't done 3d in c# before, so I wanted to ask what's the
method/library of choice for that?
Thanks

A simple way to "bundle" .htm files containing x-jquery-tmpl templates?
A simple way to "bundle" .htm files containing x-jquery-tmpl templates?
My application performs a $.get of a half-dozen .htm files containing
x-jquery-tmpl templates. I organized those .htm files based on areas of
responsibility, which saved me from any scrolling-induced carpal tunnel
during development.
I'm wondering if there's a way to "bundle" these .htm files at compile
time, similar to the script/CSS bundling in MVC, such that it's only one
HTTP request at runtime but still convenient for me to manage them?

Full Width - Normal Height BG Img
So I have been over and over all the pages on google looking for some code
that will help me fix my stretch width background image. I'm looking to
make my background image fit all browser resolutions width, the height
must remain the height it is on the image.
So far my code has given me a full width background but didn't stretch the
image so its full width but the image didn't budge.

Why does frozen spinach have so much less iron than fresh spinach?
Why does frozen spinach have so much less iron than fresh spinach?
I have been trying to increase my iron intake and was dismayed to learn
that my frozen spinach only has 2% of my daily iron needs while fresh
cooked spinach has about 20%. I have been under the impression that
freezing vegetables preserves their nutrients from the moment they are
picked/frozen and that transporting fresh vegetables across the country
depletes the nutrients.
There was a whole about this some time ago either on TV or the internet or
someplace.
So when I read the back of my frozen spinach container I was really
surprised to find that it only has 2% of what I need.
Why is this? Is there a difference between the kinds of spinach that are
grown for canning/fresh/frozen? Does freezing break something in the case
of spinach? Does this happen with all fresh green leafy vegetables?
Thank you for your time.

Multidimensional Array structure to PHP HTML output?
Multidimensional Array structure to PHP HTML output?
I have repeated sections in my web site.
I'm trying to decrease them,
My approach is one time i will create a html schema (predefined as array),
via this schema my function undestranding that what kind of output user
needs and outputs results according to my variables..
My problem is I could not find a way to complete situation..
Input variables might be (infinitive)
$vals = array('Country Name' => 'USA', 'Country Name' => 'Canada',
'Country Name' => 'Mexico');
$vals = array('Country Name' => 'USA', 'Country Name' => 'Canada');
$vals = array('Country Name' => 'USA');
Expected outputs are in order
<div class="lines">
<div><span>Country Name</span>USA</div>
<div><span>Country Name</span>Canada</div>
<div><span>Country Name</span>Mexico</div>
</div>
<div class="lines">
<div><span>Country Name</span>USA</div>
<div><span>Country Name</span>Canada</div>
</div>
<div class="lines">
<div><span>Country Name</span>USA</div>
</div>
Schema is the variables that is totally suitable with html
$schema = array(
array(
'tag' => 'div',
'class' => 'lines',
array(
'tag' => 'div',
array(
'tag' => 'span',
'key' => '$key'
),
'key' => '$key'
),
)
);
My function creates outputs from this schema. (Schema might be expand
accordings to user need.)
function get_output($schema, $vals, $t = -1){
$t++;
$tag = "";
$atts = array();
$keys = array();
$code = array();
foreach($schema as $k => $v){
if(is_array($v)){
$keys[] = get_output($v, $vals, $t);
} else {
switch($k){
case "tag": $tag = $v; break;
case "key": break;
case "type": break;
default: $atts[$k] = $v; break;
}
}
}
//echo $t;
//$code[] = str_repeat("\t", $t);
if($tag){
$code[] = "<$tag"; foreach($atts as $k=>$v){ $code[] = '

if($tag){
//$code[] = "\n".str_repeat("\t", $t);
$code[] = '</'.$tag.'>';
}
//print_r($code);
return implode("", $code);
}
After all this process I will just call my function with the variables.,
Schema predefined once.
$vals = array('Country Name' => 'USA', 'Country Name' => 'Canada',

How to manage pair- programming code check in user identification?
How to manage pair- programming code check in user identification?
How do you identify users when a programming pair checks in code? I heard
a complaint that, often a junior dev will be at the keyboard, using
his/her account, but is not going to be the best person to ask questions
about the code being checked in (the more senior dev is likely to have the
best answer).
Is this really a problem? Seems like a programming team could think of
some way to identify pairs and get the necessary information in their
version control software.
I also think they're not benefiting from this process if both programmers
don't know what their code does.

(Russia) Diophantine equation involving prime numbers
(Russia) Diophantine equation involving prime numbers
Find all pairs of prime nummbers $p,q$ such that $p^3 - q^5 = (p+q)^2$.
It's obvious that $p>q$ and $q=2$ doesn't work, then both $p,q$ are odd.
Assuming $p = q + 2k$ we conclude, by the equation, that $k|q^3 - q - 4$
because $\gcd(k,q)=1$ (else $p$ is not prime) and $k=1$ has no solution.
I also tried to use some modules, but I couldn't.

Autofill with variable number of rows
Autofill with variable number of rows
I am trying to automate a monthly report where the final autofill is based
on variable number of rows that change monthly with the change in # of
clients. For example: if this month I have 25 clients, I could easily
hardcode that I want to create 25 rows of my report. But in the next month
when I have 30 clients, my code still would say 25 and therefore would
miss five clients.
If anyone has any insight that would be very helpful as I feel like there
should be a way to accomplish this that I am just completely missing on my
own.
Thanks.

Best Package for Sparse Matrix Multiplication
Best Package for Sparse Matrix Multiplication
I am looking for the best package for sparse matrix multiplication on
single core solution. I am not looking for CUDA, MPI or OpenMP solutions.
My preference for languages in decreasing order : Matlab, Python, C/C++.
Matlab has its own matrix multiplication function which can be used for
sparse matrix multiplication. But are there any better package(s)
available ?

((((((((((((( __ READ __ BEFORE ___ DELETED ___ BY ___ MODS ___
))))))))))))))
You are about to be provided with information to
start your own Google.
Some people posted comments and said this can not
be done because google has 1 million servers and we do not.
The truth is, google has those many servers for trolling
purposes (e.g. google +, google finance, youtube the bandwidth consuming
no-profit making web site, etc ).
all for trolling purposes.
if you wanted to start your own search engine...
you need to know few things.
1 : you need to know how beautiful mysql is.
2: you need to not listen to people that tell you to use a framework
with python, and simply use mod-wsgi.
3: you need to cache popular searches when your search engine is running.
3: you need to connect numbers to words. maybe even something like..
numbers to numbers to words.
in other words let's say in the past 24 hours people searched for
some phrases over and over again.. you cache those and assign numbers
to them, this way you are matching numbers with numbers in mysql.
not words with words.
in other words let's say google uses 1/2 their servers for trolling
and 1/2 for search engine.
we need technology and ideas so that you can run a search engine
on 1 or 2 dedicated servers that cost no more than $100/month each.
once you make money, you can begin buying more and more servers.
after you make lots of money.. you probably gonna turn into a troll
too like google inc.
because god is brutal.
god is void-state
it keeps singing you songs when you are sleeping and says
"nothing matters, there is simply no meaning"
but of course to start this search engine, you need a jump start.
if you notice google constantly links to other web sites with a
trackable way when people click on search results.
this means google knows which web sites are becoming popular
are popular, etc. they can see what is rising before it rises.
it's like being able to see the future.
the computer tells them " you better get in touch with this guy
before he becomes rich and becomes un-stopable "
sometimes they send cops onto people. etc.
AMAZON INC however..
will provide you with the top 1 million web sites in the world.
updated daily in a cvs file.
downloadable at alexa.com
simply click on 'top sites' and then you will see the downloadable
file on the right side.
everyday they update it. and it is being given away for free.
google would never do this.
amazon does this.
this list you can use to ensure you show the top sites first in your
search engine .
this makes your search engine look 'credible'
in other words as you start making money, you first display things
in a "Generic" way but at the same time not in a "questionable" way
by displaying them based on "rank"
of course amazon only gives you URLS of the web sites.
you need to grab the title and etc from the web sites.
the truth is, to get started you do not need everything from web sites.
a title and some tags is all you need.
simple.
basic.
functional
will get peoples attention.
i always ask questions on SO but most questions get deleted. here's
something that did not get deleted..
How do I ensure that re.findall() stops at the right place?
use python, skrew php, php is no good.
do not use python frameworks, it's all lies and b.s. use mod-wsgi
use memcache to cache the templates and thus no need for a template engine.
always look at russian dedicated servers, and so on.
do not put your trust in america.
it has all turned into a mafia.
google can file a report, fbi can send cops onto you, and next thing you know
they frame you as a criminal, thug, mentally ill, bipolar, peadophile, and
so on.
all you can do is bleed to death behind bars.
do not give into the lies of AMERICA.
find russian dedicated servers.
i tried signing up with pw-service.com but i couldn't do it due to
restrictions with their russian payment systems and so on..
again, amazon's web site alexa.com provides you with downloadable
top 1 mil web sites in the form of a cvs file.
use it.
again, do not give into python programmers suggesting frameworks for python.
it's all b.s. use mod_wsgi with memcache.
again, american corporations can ruin you with lies and all you can do is
bleed to death behind bars
again, a basic search engine needs : url, title, tags, and popular searches
can be "cached" and words can be connected to "numbers" within the mysql.
mysql has capabilities to cache things as well.
cache once, cache twice, and you will not need 1 million servers in order
to troll.
if you need some xdotool commands to deal with people calling you a troll
here it is;
xdotool key ctrl+c
xdotool key Tab Tab Tab Return
xdotool type '@'
xdotool key ctrl+v
xdotool type --clearmodifiers ', there can not be such thing as a `troll`

You are about to be provided with information to
start your own Google.
Some people posted comments and said this can not
be done because google has 1 million servers and we do not.
The truth is, google has those many servers for trolling
purposes (e.g. google +, google finance, youtube the bandwidth consuming
no-profit making web site, etc ).
all for trolling purposes.
if you wanted to start your own search engine...
you need to know few things.
1 : you need to know how beautiful mysql is.
2: you need to not listen to people that tell you to use a framework
with python, and simply use mod-wsgi.
3: you need to cache popular searches when your search engine is running.
3: you need to connect numbers to words. maybe even something like..
numbers to numbers to words.
in other words let's say in the past 24 hours people searched for
some phrases over and over again.. you cache those and assign numbers
to them, this way you are matching numbers with numbers in mysql.
not words with words.
in other words let's say google uses 1/2 their servers for trolling
and 1/2 for search engine.
we need technology and ideas so that you can run a search engine
on 1 or 2 dedicated servers that cost no more than $100/month each.
once you make money, you can begin buying more and more servers.
after you make lots of money.. you probably gonna turn into a troll
too like google inc.
because god is brutal.
god is void-state
it keeps singing you songs when you are sleeping and says
"nothing matters, there is simply no meaning"
but of course to start this search engine, you need a jump start.
if you notice google constantly links to other web sites with a
trackable way when people click on search results.
this means google knows which web sites are becoming popular
are popular, etc. they can see what is rising before it rises.
it's like being able to see the future.
the computer tells them " you better get in touch with this guy
before he becomes rich and becomes un-stopable "
sometimes they send cops onto people. etc.
AMAZON INC however..
will provide you with the top 1 million web sites in the world.
updated daily in a cvs file.
downloadable at alexa.com
simply click on 'top sites' and then you will see the downloadable
file on the right side.
everyday they update it. and it is being given away for free.
google would never do this.
amazon does this.
this list you can use to ensure you show the top sites first in your
search engine .
this makes your search engine look 'credible'
in other words as you start making money, you first display things
in a "Generic" way but at the same time not in a "questionable" way
by displaying them based on "rank"
of course amazon only gives you URLS of the web sites.
you need to grab the title and etc from the web sites.
the truth is, to get started you do not need everything from web sites.
a title and some tags is all you need.
simple.
basic.
functional
will get peoples attention.
i always ask questions on SO but most questions get deleted. here's
something that did not get deleted..
How do I ensure that re.findall() stops at the right place?
use python, skrew php, php is no good.
do not use python frameworks, it's all lies and b.s. use mod-wsgi
use memcache to cache the templates and thus no need for a template engine.
always look at russian dedicated servers, and so on.
do not put your trust in america.
it has all turned into a mafia.
google can file a report, fbi can send cops onto you, and next thing you know
they frame you as a criminal, thug, mentally ill, bipolar, peadophile, and
so on.
all you can do is bleed to death behind bars.
do not give into the lies of AMERICA.
find russian dedicated servers.
i tried signing up with pw-service.com but i couldn't do it due to
restrictions with their russian payment systems and so on..
again, amazon's web site alexa.com provides you with downloadable
top 1 mil web sites in the form of a cvs file.
use it.
again, do not give into python programmers suggesting frameworks for python.
it's all b.s. use mod_wsgi with memcache.
again, american corporations can ruin you with lies and all you can do is
bleed to death behind bars
again, a basic search engine needs : url, title, tags, and popular searches
can be "cached" and words can be connected to "numbers" within the mysql.
mysql has capabilities to cache things as well.
cache once, cache twice, and you will not need 1 million servers in order
to troll.
if you need some xdotool commands to deal with people calling you a troll
here it is;
xdotool key ctrl+c
xdotool key Tab Tab Tab Return
xdotool type '@'
xdotool key ctrl+v
xdotool type --clearmodifiers ', there can not be such thing as a `troll`
unless compared to a stationary point, if you are complaining, you are not
stationary. which means you are the one that is trolling.'
xdotool key Tab Return
create an application launcher on your gnome-panel, and then select the
username in the comments section that called you a 'troll' and click the
shortcut on the gnome-panel.

Calculating seconds to millisecond NSTimer
Calculating seconds to millisecond NSTimer
Trying to work out where I have screwed up with trying to create a count
down timer which displays seconds and milliseconds. The idea is the timer
displays the count down time to an NSString which updates a UILable.
The code I currently have is
-(void)timerRun {
if (self.timerPageView.startCountdown) {
NSLog(@"%i",self.timerPageView.xtime);
self.timerPageView.sec = self.timerPageView.sec - 1;
seconds = (self.timerPageView.sec % 60) % 60 ;
milliseconds = (self.timerPageView.sec % 60) % 1000;
NSString *timerOutput = [NSString stringWithFormat:@"%i:%i", seconds,
milliseconds];
self.timerPageView.timerText.text = timerOutput;
if (self.timerPageView.resetTimer == YES) {
[self setTimer];
}
}
else {
}
}
-(void)setTimer{
if (self.timerPageView.xtime == 0) {
self.timerPageView.xtime = 60000;
}
self.timerPageView.sec = self.timerPageView.xtime;
self.timerPageView.countdownTimer = [NSTimer
scheduledTimerWithTimeInterval:0.01 target:self
selector:@selector(timerRun) userInfo:Nil repeats:YES];
self.timerPageView.resetTimer = NO;
}
Anyone got any ideas what I am doing wrong?

MAC crashed - Installing Ubuntu as single boot
MAC crashed - Installing Ubuntu as single boot
My new mac book pro crashed. Yes, I have the warranty & apple guys will
replace the hdd but I do not want this crappy apple now. I am rather
considering setting up ubuntu on this hardware.
I've taken out mac book's original hdd (that crashed) and got a new
external disk. I intend to use this new hdd with ubuntu install in my Mac.
There is no working copy of mac os in the original mac disk now.
I've seen several posts suggesting I can install ubuntu on the disk & I
have already done the install on my new ext disk.
The problem I am facing at the moment is once I take out the Ubuntu
install CD and try to boot the MAC with the new hdd (ubuntu), it doesn't
start up. This new hdd is connected as external disk only (via a usb
connector).
Should I put it inside the MAC instead.?
Are there any issues using Ubuntu as single boot on MAC?
What about MAC firmware updates?
Any points / inputs will be helpful.

CSS/SCSS only works as an inline style in the div, and does not work if I
use a class or an id
I have many imported SCSS files for third party plugins which could be the
problem, but essentially if I directly use the style attribute (inline
style) in the div the intended behavior works. But, if I create a class or
even an ID it does not apply to it.
Any suggestions on what to look into or immediate corrections would be
greatly appreciated.
<div class="box" style="margin-left: 50px; margin-right: 50px">
<div class="padded" >

However, when I change the above code to below, and add class to

Chaining jQuery promises/deferreds
Chaining jQuery promises/deferreds
I have a process where I have to send an ajax request to the server, but
need to stop a scheduler before the ajax request begins, then restart the
scheduler when the request is done.
I have got this working using the following code:
scheduler.stop()
.done(function () {
setQuestionStatus().done(scheduler.start);
});
But it seems that there should be a simpler way to write this, such as:
scheduler.stop().then(setQuestionStatus).then(scheduler.start);
My problem is that when written this way, setQuestionStatus and
scheduler.start are both called as soon as scheduler.stop has resolved,
rather than after each item in the chain has resolved.
Can anyone tell me what I'm doing wrong in the second example?
For your information, both scheduler.stop and setQuestionStatus return a
promise using the pattern:
var setQuestionStatus = function(){
return $.Deferred(function (def) {
// Do stuff
def.resolve();
}).promise();
}

Besides these, is there any way to open ctrl-p menu on the

desires.
I would appreciate your helps.

Using Math Symbols Stored in an Array as a String
Using Math Symbols Stored in an Array as a String
I'm very new to Ruby and I'm trying to use math symbols that are stored in
an array as strings to perform math. This is for a Reverse Polish Notation
calculator I'm working on. For example:
var = ['1','2','+']
I've puzzled through enough regular expressions to figure out how to
differentiate numbers from non-numbers in an if statement, but I'm trying
to figure out how I could make the following work to produce -1.
var[0] var[2] var[1] #=> 1 - 2
Does anyone know how to change the string '-' back into the math symbol?

Everything was fine until there was a BSOD on my computer for unknown

Is there any reason why this happens and how can I possibly fix this issue ?

contents it just creates another one (similarilly named) and does not do
anything with the targeted folder.
I'm using this command: rm -rf "$MINECRAFT_PATH/server.log backups/*"
This command is executed in a bash script.
The variable $MINECRAFT_PATH does contain the correct path. The folder
created has this name: server.log.backups (Note the dot between log and
backups). But the targeted folder has this name: server.log backups. This
folder does exist and this is not the problem.
I'm currently writing a start script for a minecraft game server. In this
script I included a backup script.
This backup script works almost perfect but instead of deleting a folders
contents it just creates another one (similarilly named) and does not do
anything with the targeted folder.

ng-repeat a single element over nested objects
ng-repeat a single element over nested objects
Say I have an object with keys corresponding to products and values
corresponding to objects which in turn have keys corresponding to price
points at which those products have sold, and values corresponding to
amount sold.
For example, if I sold 10 widgets at $1 and 5 widgets at $2, I'd have the
data structure:
{ 'widget': {'1': 10, '2': 5} }
I'd like to loop over this structure and generate rows in a table such as
this one:
thing price amount
---------------------
widget $1 10
widget $2 5
In Python it's possible to nest list comprehensions to traverse lists data
structures like this. Would such a thing be possible using ng-repeat?

Java Netty Client Channel Closing
Java Netty Client Channel Closing
I'm building a server and client to support multiple connections from
different people. I have done the decoders and encoders. I use ByteBuffer
and convert that into ChannelBuffer to send data. During a session, if
correct session credentials are met, then client opens up the Login
JFrame. After the JFrame is opened, the channel connected to server is
closed automatically. I'm assuming it was because the client isnt
receiving or sending any data or has nothing to do. So how can I make the
client keep checking for incoming data while during the JFrame stage?

A local repository to update games?
A local repository to update games?
I have a computer cafe. Updating and maintaining files (particularly
games) has been a hassle for me and my employees. In addition, I am not
willing to pay for something like G-Cafe Management Program. I am familiar
with programming languages like C, PHP, JAVA, but I am neither aware of
what logic and algorithm I would use for my objective nor familiar with
networking
My friend suggested I use a local repository, so I researched topics
regarding the same matter. But it turns out that I have a question that
was not answered by discussions I've read.
This is how I view how my update was going to work:
I plan on updating games through this flow: [(Internet -> Server) ->
(Server -> Client]. If there are game updates, the local server will
download it through the internet; then, the client will copy or download
these files from the local server.
Seeing that games have autoupdaters, I plan on placing all of the games
inside the repository (in the server) and the client stations will connect
to that repository. But then again, SVN works with revisions, am I right?
Are there any suggestions or ideas whether how will I be able to update
client games through SVN / Git (of course from the server)? Or if there
are any other ways?
I was playing too dumb.. :(

Generating non-random data according to an already existing dataset and applying it to another dataset
Generating non-random data according to an already existing dataset and
applying it to another dataset
I am looking for a package in R or a tool that could help me generate data.
I have 1 dataset that has only one element and then I have a second
dataset that has approx. 450 elements. I obviously can't perform a T-test
with what I have, therefore I have to generate "artificial" data in my
first dataset in accordance with the elements from my second dataset.
Background: The first dataset with the one element corresponds to the
expression of a mutated gene for one patient and the second dataset
corresponds to the expression of the same gene that has not been mutated
for several patients.
I tried searching for solutions but I only found options for resampling
already existing data or creating new random data, which I do not want to
do.
Thank you for your help!

Android monitor won't recognize my Android (Galaxy S2) on Windows 8
Android monitor won't recognize my Android (Galaxy S2) on Windows 8
I'm trying to build and run a cordova project on my Galaxy S2. I'm having
trouble getting my windows 8 HP Pavilion intel core i5 laptop to recognize
the phone. Here's the two things that have worked for me:
A. I've gone through the whole process easily on my windows 7 desktop, so
it isn't my phone's settings
B. I can transfer files from my phone on the windows 8 machine (ie its
icon appears in My Computer), so its not a simple connection issue
I've followed these instructions, which look pretty identical to the
official windows 7 instruction for some reason. The result was that my
computer told me "Windows was unable to install your SAMSUNG_Android".
Going to the android monitor never shows my phone when i plug it in. I
also tried installing directly from
sdk/extras/google/usb_driver/android_winusb.inf (it tells me "The
operation completed successfully"), then restarted the computer. No Dice.
So what gives? How do I do this? Help!

Is it ok to send login details over GET request using SSL
Is it ok to send login details over GET request using SSL
I'm restricted to using JSONP for API requests from a javascript app.
The entire javascript app will be hosted over SSL.
As we are limited to GET requests when using JSONP is it ok to send login
credentials (username/password) to the API using a GET request?
I presume it wouldn't be if we weren't using SSL but it is ok because we
are. Correct?
Thanks!

Doctrine 2 base entities like those in doctrine 1?
Doctrine 2 base entities like those in doctrine 1?
I'm starting a new project with Symfony2/Doctrine2 and I generated my
entities from the DB with the mapping:convert and mapping:import commands.
My entities are fine, but I only have the generated entities. Back in
Doctrine1/Symfony1, you had your entities generated twice : once in the
doctrine folder, an almost empty class just extending the second one in
doctrine/base folder where all the doctrine internals were
(getters/setters, fields...) This way, you could add your own methods in
the first file where they remained untouched even if you generated again
the entities (only the doctrine/base files were modified by the
generator).
Am I missing something ?

Add Rows/Columns to a Grid dynamically
Add Rows/Columns to a Grid dynamically
I have a child userControl comprising of multiple textboxes, labels. I
need to populate these controls in Parent User control which has a Grid.
Number of child user controls that need to be populated in the parent user
control are determined at run time and can change. Basically the number
depends on the search result. So it can be from 0 to n. How can I populate
my child user control in parent control?
Is there a better alternate to using a GRID? Any help will be much
appreciated. Thanks

Maximum related to Nonnegative Matrix
Maximum related to Nonnegative Matrix
Suppose $A$ is a fixed nonnegative $n\times n$ matrix (i.e. $A_{ij}\geq0$
for all $i,j$). Then for any arbitrary $n$ positive numbers
$x_1,\ldots,x_n$, we denote:
$$F(x_1,\ldots,x_n)=\min_i\frac{1}{x_i}\sum_{j=1}^n x_jA_{ij}$$ Frobenius
Theorem tells us that there's always an inequality
$$F(x_1,\ldots,x_n)\leq\rho(A)$$ where $\rho(A)$ is the spectral radius of
$A$.
Here my question is, what is the maximum of $F(x_1,\ldots,x_n)$ ? Is it
just $\rho(A)$ ? Or there's no maximum but a supremum? Thanks a lot for
your help.

For example
You have textbox1 and textbox2 and want to have a - in hte middle

I have tried this

Cassandra: choosing a Partition Key
Cassandra: choosing a Partition Key
I'm undecided whether it's better, performance-wise, to use a very
commonly shared column value (like Country) as partition key for a
compound primary key or a rather unique column value (like Last_Name).
Looking at Cassandra 1.2's documentation about indexes I get this:
"When to use an index Cassandra's built-in indexes are best on a table
having many rows that contain the indexed value. The more unique values
that exist in a particular column, the more overhead you will have, on
average, to query and maintain the index. For example, suppose you had a

"When not to use an index
Do not use an index to query a huge volume of records for a small number
of results. For example, if you create an index on a column that has many
distinct values, a query between the fields will incur many seeks for very
few results. In the table with a billion users, looking up users by their
email address (a value that is typically unique for each user) instead of
by their state, is likely to be very inefficient. It would probably be
more efficient to manually maintain the table as a form of an index
instead of using the Cassandra built-in index. For columns containing
unique data, it is sometimes fine performance-wise to use an index for
convenience, as long as the query volume to the table having an indexed
column is moderate and not under constant load."
Looking at the examples from CQL's SELECT for
"Querying compound primary keys and sorting results", I see something like
a UUID being used as partition key... which would indicate that it's
preferable to use something rather unique?
I'm undecided whether it's better, performance-wise, to use a very
commonly shared column value (like Country) as partition key for a
compound primary key or a rather unique column value (like Last_Name).
Looking at Cassandra 1.2's documentation about indexes I get this:
"When to use an index Cassandra's built-in indexes are best on a table
having many rows that contain the indexed value. The more unique values
that exist in a particular column, the more overhead you will have, on
average, to query and maintain the index. For example, suppose you had a
user table with a billion users and wanted to look up users by the state
they lived in. Many users will share the same column value for state (such
as CA, NY, TX, etc.). This would be a good candidate for an index."

If $\cos^4 \theta −\sin^4 \theta = x$. Find $\cos^6 \theta − \sin^6 \theta $ in terms of $x$.
If $\cos^4 \theta −\sin^4 \theta = x$. Find $\cos^6 \theta −
\sin^6 \theta $ in terms of $x$.
Given $\cos^4 \theta −\sin^4 \theta = x$ , I've to find the value of
$\cos^6 \theta − \sin^6 \theta $ .
Here is what I did: $\cos^4 \theta −\sin^4 \theta = x$.
($\cos^2 \theta −\sin^2 \theta)(\cos^2 \theta +\sin^2 \theta) = x$
Thus ($\cos^2 \theta −\sin^2 \theta)=x$ , so $\cos 2\theta=x$ .
Now $x^3=(\cos^2 \theta −\sin^2 \theta)^3=\cos^6 \theta-\sin^6
\theta +3 \sin^4 \theta \cos^2 \theta -3 \sin^2 \theta \cos^4 \theta $
So if I can find the value of $3 \sin^4 \theta \cos^2 \theta -3 \sin^2
\theta \cos^4 \theta $ in terms of $x$ , the question is solved. But how
to do that ?

Android billing - purchase subscription code does not do anythnig
I have this code that executes when the user presses a button to buy a
subscription
Button support_us = (Button)findViewById(R.id.support_us);
support_us.setOnClickListener(new Button.OnClickListener()
{
public void onClick(View v)
{
// GETS THIS FAR
ArrayList skuList = new ArrayList();
skuList.add("basicsubscription");
Bundle querySkus = new Bundle();
querySkus.putStringArrayList("basicsubscription", skuList);
try
{
Bundle skuDetails = mService.getSkuDetails(3,
getPackageName(), "subs", querySkus);
int response = skuDetails.getInt("RESPONSE_CODE");
if (response == 0)
{
ArrayList<String> responseList
= skuDetails.getStringArrayList("DETAILS_LIST");
for (String thisResponse : responseList)
{
JSONObject object = new JSONObject(thisResponse);
String sku = object.getString("basicsubscription");
String price = object.getString("price");
if (sku.equals("premiumUpgrade"))
{
//mPremiumUpgradePrice = price;
}
else
if (sku.equals("gas"))
{
//mGasPrice = price;
}
}
}
else
{
}
Bundle buyIntentBundle = mService.getBuyIntent(3,
getPackageName(),
"basicsubscription", "subs",
"bGoa+V7g/yqDXvKRqq+JTFn4uQZbPiQJo4pf9RzJ");
PendingIntent pendingIntent =
buyIntentBundle.getParcelable("BUY_INTENT");
startIntentSenderForResult(pendingIntent.getIntentSender(),
1001, new Intent(), Integer.valueOf(0),
Integer.valueOf(0),
Integer.valueOf(0));
}
catch ( Exception e )
{
}
}
});
But it doesn't seem to do anything. Would anyone know what may be wrong
with it?
Thanks!
