EC2 instances - more than one startup mode (maintenance / production)
It is my understanding that in order to make use of EC2 spot instances,
the AMI for the instances must be configured to start doing whatever it's
supposed to do immediately upon bootup, and continue doing it until it's
done or the instance is terminated.
That's not a problem in itself, but I will be needing periodically to
update the AMI with new software and/or configuration scripts, so I'll
occasionally need to bring up a regular instance that I can ssh into and
tinker, which won't play nice with boot scripts that immediately start
trying to Do Stuff (for instance, while I am updating the AMI for a bunch
of compute workers, the associated control server will probably be down).
Is there a way to configure two (or more) boot modes for the same AMI?
Sort of like good old-fashioned SysV run levels ... which would work fine
for this application, in fact, except I don't see any way to control the
kernel command line from the EC2 web or CLI interfaces.
(Operating system inside the AMI is Linux, if that matters.)

Coupon collector's problem worst case time?
Coupon collector's problem worst case time?
The expected time is $n Hn$. So for 9 coupons we get ~26 trials. But what
is the probability that all coupons have been collected after 26 trials?
How do we know the number of trials required to collect all with arbitrary
certainty?

JPA - Optional columns
JPA - Optional columns
We have many customers data in separate databases per customer which
should have the same schema/table structures. However there is a table
that has extra columns in some databases compared to others.
For example for customer A there is a table X with columns a, b, c, d. For
customer B there is a table X with columns a, c, d. I need to capture b if
it exists but can ignore it if not.
Is there a way to tell JPA to ignore those columns if they don't exist?
@Basic(optional=true) reads exactly like what I want but the documentation
indicates it is for another purpose.
Currently I get, as expected, Unknown column 'table.field' in 'field list'
P.S. I can't just add the columns to the databases that don't have them
unfortunately.

Optimize multiple JOINs in MySQL
Optimize multiple JOINs in MySQL
I have this MySQL which should be correct syntax:

missing something here, how can I increase the efficiency? My goal here

Getting rows from a data frame which satisfy a condition in pandas
Getting rows from a data frame which satisfy a condition in pandas
I have a data frame and I have a range of numbers. I want to find the rows
where values in a particular column lie in that range.
This seems like a trivial job. I tried with the techniques given here -
http://pandas.pydata.org/pandas-docs/dev/indexing.html#indexing-boolean
I took a simple example:
In [6]: df_s
Out[6]:
time value
0 1 3
1 2 4
2 3 3
3 4 4
4 5 3
5 6 2
6 7 2
7 8 3
8 9 3
In [7]: df_s[df_s.time.isin(range(1,8))]
Out[7]:
time value
0 1 3
1 2 4
2 3 3
3 4 4
4 5 3
5 6 2
6 7 2
Then, I tried with a sample from the data set I am working with which has
timestamp and value as columns:
In [8]: df_s = pd.DataFrame({'time': range(1379945743841,1379945743850),
'value': [3,4,3,4,3,2,2,3,3]})
In [9]: df_s
Out[9]:
time value
0 1379945743841 3
1 1379945743842 4
2 1379945743843 3
3 1379945743844 4
4 1379945743845 3
5 1379945743846 2
6 1379945743847 2
7 1379945743848 3
8 1379945743849 3
In [10]: df_s[df_s.time.isin(range(1379945743843,1379945743845))]
Out[10]:
Empty DataFrame
Columns: [time, value]
Index: []
Why doesn't the same technique work in this case? What am I doing wrong?
I tried another approach:
In [11]: df_s[df_s.time >= 1379945743843 and df_s.time <=1379945743845]
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)
<ipython-input-11-45c44def41b4> in <module>()
----> 1 df_s[df_s.time >= 1379945743843 and df_s.time <=1379945743845]
ValueError: The truth value of an array with more than one element is
ambiguous. Use a.any() or a.all()
Then, I tried with a bit more complex approach:
In [13]: df_s.ix[[idx for idx in df_s.index if df_s.ix[idx]['time'] in
range(1379945743843, 1379945743845)]]
Out[13]:
time value
2 1379945743843 3
3 1379945743844 4
This gives the desired result but it takes way too much time to give any
result on my original data set. It has 209920 rows and it is expected that
the number of rows will increase when I actually put my code to test.
Can anyone direct to me towards the right approach?
I am using python 2.7.3 and pandas 0.12.0
Update:
Jeff's answer worked.
But I find the isin approach more simple, intuitive and less cluttered.
Please comment if anyone has any idea why it failed.
Thanks!

In PHP would this be deemed correct?
I already wrote a post about an issue I had before about this but I had
that issue taken care of. Like my last post I have a form, text-box and a
button. I have everything done with this including Printing the original
word, Printing the number of characters in the word, Printing the word in
all caps and Printing the word in reverse order. My only issue I'm having
is trying to get whatever text I enter and then click the button to output
to Print the first letter of the word and Print the last letter of the
word. I've been doing a lot of looking around of PHP.net and I found that
substr is used to return a part of a string that I could use. The only
issue is when I write the code for it and try to execute my program it
errors out on that specific line. I'm not looking for the answer but could
someone just take a look and see what I'm doing wrong because I understand
everything completely but this is the only thing I'm hung up on.
$first = substr($_POST['entertext']);
echo "The first letter of the word is " . $first. "<br />\n";
$last = substr($_POST['entertext']);
echo "The first letter of the word is " . $last. "<br />\n";

How to select nested UL element without class in JavaScript
How to select nested UL element without class in JavaScript
In my Joomla template I've created a vertical menu including a dropdown
which should "push" the elements below away when opening a submenu
onclick. Somehow I don't get it to work..
I am trying to grab the UL inside an LI, but how can I do this in
JavaScript without the UL's having a class or ID.
I've come to this yet:
function getElements(){
var listitems = {};
for(var i = 0; i< arguments.length; i++){
var id = arguments[i];
var item = content.getElementsByTagName("li");
if (item == null)
throw new Error ("No list items found.");
listitems[id] = item;
}
return listitems;
}
Now I should get something like: (I now the following code is impossible,
but it describes what I am trying)
var nav = document.getElementById("navigation");
var nestedList = nav ul li ul.onclick(nav ul li ul.style = "display:
block";);
Thanks!

How to make last page in ViewPager completely inaccessible
How to make last page in ViewPager completely inaccessible
In an App that I am working on, I implement a ViewPager. At some point, I
want to make the last page in the ViewPager completely inaccessible. To do
that I set up the getCount() method in my SectionsPagerAdapter like this:
@Override
public int getCount() {
return mPageCount;
}
When I want to make the last page inaccessible, I just subtract 1 from
mPageCount (which is a global variable) and the user can't access it
anymore. This works but the problem is that the user still can see the
last page if he flings the ViewPager in the second-to-last page. The
ViewPager will bounce back, so he can't stay at the last page, but he can
see it. Also there is no edge effect. Basically my question is: "How do I
remove the last page from the ViewPager such that it is COMPLETELY gone
(it should appear as if that is the end of the ViewPager)?"

Grab specific data using C++ with MySQL

I am trying to grab specific information from a MySQL database in C++.
Lets assume I can connect and have my MySQL package working just fine. The
below picture is a database. I want to retrieve the name LISA and insert
it into a variable to be used later. Anyone have any idea how to do so?
The below code works too.
DATABASE:
ID NAME
1 Rico
2 John
6 Lisa
7 Max
This is my current output with the below code. I just want LISA and be
able to place in a variable.
Input id: 6
name:
6Lisa
CODE:
string id_query;
string outstr;
string str8 = "Select * From users WHERE id=";
cout << "Input id: ";
cin >> id_query;
outstr = str8.c_str() + id_query;
if (mysql_query(conn, outstr.c_str()))
{
cerr << mysql_error(conn) << endl;
cout << "Press any key to continue. . . ";
cin.get();
exit(1);

How to help Scalaz with type inference and 2 type parameters
How to help Scalaz with type inference and 2 type parameters
I have something called a Generator:
trait Generator[A, B] { def generate(in: Seq[A]): Seq[B] }
I can provide a Bind instance for this generator:
object Generator {
implicit def generatorBind[T]: Bind[({type l[B] = Generator[T, B]})#l] =
new Bind[({type l[B] = Generator[T, B]})#l] {
def map[A, B](generator: Generator[T, A])(f: A => B): Generator[T, B]
= new Generator[T, B] {
def generate(in: Seq[T]): Seq[B] = generator.generate(in).map(f)
}
def bind[A, B](generator: Generator[T, A])(f: A =>Generator[T, B]):
Generator[T, B] = new Generator[T, B] {
def generate(in: Seq[T]): Seq[B] = generator.generate(in).flatMap(v
=> f(v).generate(in))
}
}
}
Unfortunately, type inference is completely lost if I try to use my
generators as applicative instances:
val g1 = new Generator[Int, Int] { def generate(seq: Seq[Int]) = seq.map(_
+ 1) }
val g2 = new Generator[Int, Int] { def generate(seq: Seq[Int]) = seq.map(_
+ 10) }
// doesn't compile
// can make it compile with ugly type annotations
val g3 = ^(g1, g2)(_ / _)
My only workaround for now has been to add a specialised method to the
Generator object:
def ^[T, A, B, C](g1: Generator[T, A], g2: Generator[T, B])(f: (A, B) => C) =
generatorBind[T].apply2(g1, g2)(f)
Then this compiles:
val g4 = Generator.^(g1, g2)(_ / _)
Is there a workaround for this problem? I suppose there is because using
State[S, A] as a Monad poses the same kind of issue (but in Scalaz there
seems to be a special treatment for State).

What is a simple way I can position images in html5
What is a simple way I can position images in html5
Hey I have been trying to use the
style="position:absolute;TOP;55px right;170px"
format to position images but it does not seem to be working.
This is my code
I was wondering if anyone who could tell me a simple way to position it on
the screen. It is preferred no css but if there is I think I could handle
it.
Cheers

Bootstrap and Reveal.js
Bootstrap and Reveal.js
I'm using Bootstrap and Reveal.js to create a slide style web page for a
small portfolio. Everything is working well together but what I'm noticing
is that when my navbar collapses and I click the navbar toggle button, my
webpape/slide show will scroll back to the top while the menu expands.
So what I'm guessing is that the javascript that controls the navbar
collapse and expand is conflicting with Reveal.js. So what I want to know
is if someone has come across anything like this and how they resolved it.
What I thinking is that somewhere in bootstraps javascript is that there
is a bit to set the scroll (0,0) Is this true or is the problem with
Reveal.js?
Any help is appreciated

Error in connecting with mysql using android
Error in connecting with mysql using android
I'm developing an app which will retrieve some data from mysql database. I
needed to connect my app with mysql directly to do this. I know, that i
have to use an ip address instead of localhost in getconnection method.
here is the code :
Class.forName("com.mysql.jdbc.Driver");
Log.i("output","class");
con =
DriverManager.getConnection("jdbc:mysql://192.168.1.1:3306/outsidelaundry",
"root", "");
Log.i("output","connection");
Statement stmt = con.createStatement();
String query = "select Name from nonmember";
ResultSet rs = stmt.executeQuery(query);
while(rs.next())
{
val = val + rs.getString(1) + "\n";

To be honest i don't know what is the ip address i want to use to get

too. Please help me with this.

Maven - activate profile based on project property
Maven - activate profile based on project property
Hi I am trying to achieve something like this:
In a parent pom, I have
<profile>
<activation>
<property>
<name>Compile</name>
<value>${project.artifactId}</value>
...
so that if I run mvn -DCompile=mod1 install under the parent pom, it will
only apply the profile settings to module 1, but not the others.
Similarly, if I have
<profile>
<activation>
<property>
<name>Compile</name>
<value>${project.packaging}</value>
...
then running mvn -DCompile=war install under the parent pom, it will only
apply the profile settings to those to be packed as war but not jar nor
pom.
I tried but it didnt work as expected. Did I miss anything? Please help.
P.S. no need to suggest workarounds as I am only interested on this
method. Simply answer it is not possible with reason if thats the case.
Thank you

Amazon RDS instance in EBS: Access Denied when trying from Java application in Tomcat
Amazon RDS instance in EBS: Access Denied when trying from Java
application in Tomcat
I created an EBS instance including the RDS instance based on MySQL.
I have access to the EC2 instance using SSH via PuTTY and using the MySQL
Workbench I've got access to the RDS instance as well and I can create
tables and insert data in them.
I developed a Java application using Netbeans 7.3.1 and when I run the
application locally while connecting to the MySQL instance on RDS the
application shows the same problem although I can connect to MySQL from
within Netbeans without a problem, ie I can connect to the database. But
as soon as I deploy my simple application onto EBS and run the same
application I get the error "Access denied for user ''@'' (using password:
YES)"
I added the IP to the Security Group of my RDS instance as well as the EBS
instance. Just to be sure.
Still I got the Access Denied error. The JDBC_CONNECTION_STRING
environment variable I've set up is
"jdbc:mysql://.cdydcnmtkkhw.us-west-1.rds.amazonaws.com:3306/ebdb?user=&password="
When I use any of the tools to connect to this database with that
information all works, when I try to connect from my Java application
running in Tomcat, I get the Access Denied message.
The Java call I'm using is:
private java.sql.Connection connect =
DriverManager.getConnection(jdbcConnect);
Any help would be appreciated as I'm totally stuck here.

How to transpose a small file with text spread over multiple lines in java?
How to transpose a small file with text spread over multiple lines in java?
for ex: From:
ab ch as asd lk
ere lk oi qw
weq aa q uro ppp lkj
To:
ab ere weq
ch lk aa
as oi q
asd qw uro
lk - ppp
- - lkj
assuming a - for missing items, for ex: (5,2) place
I have recently started with java and wanted to know what would be the
best way to manage such transpose conversion in java? Should I use an
Arraylist of arraylist, keeping in mind varying length of each line?
I have seen some of the existing questions on in-situ transposition, but,
as I will be working on small files, if someone could help me with an
easier to understand and implement solution, that would be really helpful.

Where max-wiidth (@media) css come from?
Where max-wiidth (@media) css come from?
I have this problem, there are 2 pages, that some part of the code is
repeated, to this part of code, I apply this css:
@media (max-width: 767px){
.sliderContent{
width:100%;
}
}
When I check one page in iphone, it loads this css, but when I check the
other does not use this style.
I have added an alert with the screen size in both pages, and both have
the same width.
Do you know where the max-width is taken? that could be making the
difference between the two pages?
Can the html somehow affect the size of the min-width??
Thanks in advance

C# variable contents altered when using a debugger
C# variable contents altered when using a debugger
In my C# program, I parse an XML file, which has been created before with
XSLT. When I normally run the program, variable extraClasses contains 3
nodes. The problem is that the selector I am using must return 2 nodes
when applied to this specific XML.
Trying to find the bug in my code, I used a debugger. When I examined the
value of variable extraClasses, the node count was 2, and the result was
the expected. When the variable is not examined, node count is 3 and the
results are wrong.
Furthermore, when I add an if statement to check if the extraClasses count
is more than 2, after the assignment, my program works fine
(extraClasses.Count = 2).
Why is this happening? Why the value examination alters the contents of
the variable? I am using C# and .NET Framework 4.
var extraClasses = xml.SelectNodes("//Class[@level='2']");
foreach (XmlElement extraClass in extraClasses) {
/* create some new nodes and append to the xml */
}

how to secure data in sharepoint custom list
how to secure data in sharepoint custom list
I have stored database connection string in a column of SharePoint custom
list. Through c# code i used to fetch the value from that column and my

string is visible to everyone having access to the list. How we can
encrypt that value so that it cannot be visible to everyone but my
application can be connected to the database with minimum or no change in
code?

Issue with collecting AspectJ pointcut context and avoiding mentioning all arguments of the advised method
Issue with collecting AspectJ pointcut context and avoiding mentioning all
arguments of the advised method
I use AspectJ in order to check whether an object does belong to the
current user. The advised method is actually a Spring MVC controller
method. I use an annotation placed on that controller method in order to
apply the crosscutting security advice.
The issue I have is that the controller method has quite a few arguments.
I would like to avoid mentioning all arguments in the aspectJ source
because those can change (argument name, type, etc.) but I still have to
collect the pointcut context.
To sum up of the N arguments present in the method, I only need to use two
(member and advertisementId). How can I avoid mentioning the N arguments?
My pointcut:
public pointcut
advertisementBelongsToMemberControllerCheck(FamilyAdvertisementInfo
familyAdvertisementInfo, long advertisementId, Model model, Member member)
: execution(@AdvertisementExistsAndBelongsToMemberCheck * * (..))
&& args(familyAdvertisementInfo,advertisementId, model, member);
My advice:
before(FamilyAdvertisementInfo familyAdvertisementInfo, long
advertisementId, Model model, Member member) :
advertisementBelongsToMemberControllerCheck(familyAdvertisementInfo,advertisementId,
model, member) {
if
(!advertisementService.advertisementExistsAndBelongsToMember(advertisementId,
member)) {
throw new AccessDeniedException("Advertisement does not belong
to member!");
}
}
The annotation:
@Retention(RetentionPolicy.RUNTIME)
public @interface AdvertisementExistsAndBelongsToMemberCheck {
}
And finally, the advised controller method:
@RequestMapping(value = "/family/edit/{advertisementId}", method =
RequestMethod.GET, produces = "text/html")
@AdvertisementExistsAndBelongsToMemberCheck
public String editFamilyAdvertisementForm(@ModelAttribute
FamilyAdvertisementInfo familyAdvertisementInfo, @PathVariable long
advertisementId, Model model, @CurrentMember Member member/* the currently
logged in user */) {
FamilyAdvertisement advertisement =
advertisementService.findFamilyAdvertisement(advertisementId);
familyAdvertisementInfo.setFamilyAdvertisement(advertisement);
populateFamilyAdvertisementModel(model, familyAdvertisementInfo,
member);
return "advertisement/family/edit";
}

it innitiates my main menu. and from the main menu i want to innitiate
another class named ViewTeamStatistics
this is the actionperformed. this is what is supposed to tell the program
to open the frame after i press the button
private void vtsActionPerformed(java.awt.event.ActionEvent evt) {

Like dereferencing, then getting the address of the expression. Is there a

on Wordpress my post shows up on my Facebook business page.
I noticed that the featured image is not being displayed on my Facebook
page. Can someone explain to why I am not seeing the featured Wordpress
post image in the Facebook post?
Please take a look at my Facebook site:
http://www.facebook.com/awesomelowcarb
See the first post which is a recipe. The image that I would expect is not
displayed.
I have seen others who have experienced similar problems but haven't seen
any solutions that are applicable to me.
Let me know if you need more info.
Thanks in advance, Andrew

C# getting "string length can not be zero" inside dialog InitializeComponent
C# getting "string length can not be zero" inside dialog InitializeComponent
I moved few dialog froms from one class library to another (drag and drop)
in the same solution (Both are c# class librarians) Then at run time I
start getting get the error inside the InitializeComponent method of
myform.Designer.cs of moved and previously exists forms in that target dll
at line similar to
this.pictureBox1.Image = global::mydll.Properties.Resources.Webster;
The exception is "string length can not be zero".
Sometimes the form will load correctly the first time but not after that.
Do you ever have issues moving forms from one project to another?
I did updated all namespaces to use the target dll namespace.
Thank you for your help.

ASP.NET Export - Response not ending?
ASP.NET Export - Response not ending?
I'm trying to export some text to a text file, and that part works fine.
The trouble is that the text files get a bunch of HTML/.NET output at the
bottom of them... In other words, it's like the response isn't ending and
the page is trying to write the rest of the page. Here's the code:
Private Sub WriteData(ByRef Context As System.Web.HttpContext,
Data As List(of String), fileName as String)
With Context.Response
.Clear()
.ClearHeaders()
.ClearContent()
.AddHeader("content-disposition", String.Format("attachment;
filename={0}", fileName))
.ContentType = contentType
End With
For Each curValue in Data
Context.Response.Write(curValue)
Context.Response.Write(Environment.NewLine)
Next
Context.ApplicationInstance.CompleteRequest()
Context.Response.End()
End Sub
To call this, I just pass the HttpContext.Current and a list of data.
Does anybody know why this might happen? I'm not sure how to interpret it,
and I've looked all over without much luck. My assumption was that the
response wasn't actually ending with "Response.End()"...
Thanks,
Mike

Google Apps Script - How To Publish / Install A Container-Bound Script
I have a document container-bound script, that I would like to publish, I
would like to make it available to people in my google apps organization.
I know the script gallery is only available to spreadsheet apps, so how do
I publish it. Or, more specifically, currently the script is bound to one
document, how do I make it run on all documents? My user base is fairly
small, about 300 people, and I can have each one of them install it if
need be.

I am trying to do some arithmetic operations with arrays. such as array
[1,2,3] + [1,2,3] should return [2,4,6]. However when I tried to do the
next arithmetic [1,2,3] * [1,2,3] = it returns [4,16,36] instead of

permanently updated to the result of the first arithmetic operation.
Please help a bit deeper than conceptual support, such as providing me
some alternative coding suggestions, since I am learning C++ and this has
been the toughest chapter that I encountered. Thank you very much.

random file by inode number, is that possible?

Let's say I have the following text:
Steps toward this goal include: Increasing efficiency of mobile networks,
data centers, data transmission, and spectrum allocation Reducing the
amount of data apps have to pull from networks through caching,
compression, and futuristic technologies like peer-to-peer data transfer
Making investments in accessibility profitable by educating people about
the uses of data, creating business models that thrive when free data
access is offered initially, and building out credit card infrastructure
so carriers can move from pre-paid to post-paid models that facilitate
investment If the plan works, mobile operators will gain more customers
and invest more in accessibility; phone makers will see people wanting
better devices; Internet providers will get to connect more people; and
people will receive affordable Internet so they can join the knowledge
economy and connect with the people they care about.
As you can tell by reading the text, these are multiple sentences (a list
of points). How can I split this text into sentences? I've tried using
python NLTK but no luck. Checking for uppercase letters won't work either,
as it isn't very reliable.
Any ideas on how to solve this problem?
Thanks.

How to avoid checking for empty value in Haskell?
How to avoid checking for empty value in Haskell?
I'm trying to grasp how Haskell programs can avoid testing for "empty
value". I am struggling to get rid of case expression in this program:
main = do url:outputPath:[] <- getArgs
let maybeUri = parseURI url
case maybeUri of
Just uri -> download uri outputPath
Nothing -> return ()
My very rough understanding is that I should use monad transformer so that
I can use single mappend on Maybe value within IO monad and 'do' syntax
should be able to support it. How can I achieve this?

I'm writing a program that basically creates a list of items. It first
stores all the item numbers in a List of strings. After that, after each
item, I want the program to store multiple lines of descriptions. Is there
a way to add new data between two pre-existing points of data in the List
without destroying any pre-existing data? I know in C++ you could push
back a Vector, but I'm not sure if you can or how to do the same in C#.

Twig - Automatically insert templatename as html comment
Twig - Automatically insert templatename as html comment
I am working on a php project and using twig as template engine and
wondering if there is a possibility to automatically add the used template
filename/path into a twig template as html-comment?
That would be great for debugging, since I could have a look at the html
code and find out, in which twig file I have to look, if I want to change
something.
For example, the result should look like this:
<!-- start tpl/layout.twig -->
<html>
<head></head>
<body>
<!-- start tpl/header.twig -->
<header>My header</header>
<!-- end tpl/layout.twig -->
<!-- start tpl/content.twig -->
<section>
<!-- start tpl/article.twig -->
<article>blabla1</article>
<!-- end tpl/article.twig -->
<!-- start tpl/article.twig -->
<article>xyz</article>
<!-- end tpl/article.twig -->

jQuery Facebox restrict closing
jQuery Facebox restrict closing
I am using jQuery Facebox to show a list of possible currencies a user can
customise the site to however Facebox allows closing when clicking outside
the popup (dark area). I would like to force the user to select a currency
and click a button and then close facebox so my question is, is there a
way to stop the default close actions (click outside and the cross) so I
force the user to click an 'OK' (or whatever) button?
I can then close Facebox programatically (which I already know how).

How do I open/close ports in iptables based on a network service status?
How do I open/close ports in iptables based on a network service status?
I would like to have iptables dynamically open ports as a network service
is enabled and close ports as they are disabled.
Is there an established way to do this? Should I be mucking around with
iptables, /etc/init.d/* files, or clobber together my own ./script?
I don't think it provides much in added security, but it would be useful
for deployments where a full iptables configuration can be copied over for
many services, exposing ports only as those services are configured and
activated.
I am specifically using CentOS 6.2 on a Linode VPS, but I would also like
to be able to use this on an Ubuntu Server VM (12.04 LTS) or another other
Debian variant.

iptables, /etc/init.d/* files, or clobber together my own ./script?
I don't think it provides much in added security, but it would be useful
for deployments where a full iptables configuration can be copied over for
many services, exposing ports only as those services are configured and
activated.
I am specifically using CentOS 6.2 on a Linode VPS, but I would also like
to be able to use this on an Ubuntu Server VM (12.04 LTS) or another other
Debian variant.
Responsive table design by cell
Responsive table design by cell
I have this table with three cells in the first row. I'm trying to create
a design that will bring down the last cell if there is no space. So
something like 2 on top, 1 below. And as the window gets even small 1 on
each row. I'm having trouble finding anything like this.
I was able to get a responsive design to stack all cells on top of each
other depending on size but if I could find a better solution that would
be nicer.

Get added/removed/changes key=>value pairs between two arrays
Get added/removed/changes key=>value pairs between two arrays
I have two multidimensional arrays called $old and $new. I want to compare
the two arrays and see what k=>v's were added, removed, or changed between
the two.
These are the arrays:
$old = array(
'ONE' => array('a' => 1, 'b' => 2, 'c' => 3),
'TWO' => array('a' => 4, 'b' => 5, 'c' => 6),
'THREE' => array('a' => 7, 'b' => 8, 'c' => 9)
);
$new = array(
'TWO' => array('a' => 5, 'b' => 5, 'c' => 6),
'THREE' => array('a' => 7, 'b' => 8, 'c' => 9),
'FOUR' => array('a' => 1, 'b' => 2, 'c' => 3)
);
Notice that in the $new array I have removed 'ONE', added 'FOUR', and
changed the value of 'TWO'=>'a' from 4 to 5.
This is my current (working) solution, but I feel that I don't need to
write this much code and I'm unsure if it will be slow on much larger
arrays.
$added = array();
$removed = array();
$changed = array();
foreach ($old as $old_key => $old_value) {
if (!in_array($old_key, array_keys($new))) {
$removed[] = $old_value;
unset($old[$old_key]);
}
}
foreach ($new as $new_key => $new_value) {
if (!in_array($new_key, array_keys($old))) {
$added[] = $new_value;
unset($new[$new_key]);
}
}
$changed = array_udiff($new, $old, create_function(
'$a,$b',
'return strcmp(implode("", $a), implode("", $b));'
));

I am building a website where a login and register link is displayed. If
the user logs in the login link changes to a logout link which will unset
a variable. I am wondering if there is a better way to do this then

relatively new to this is why I ask I want to make sure my code is safe,
effective and efficient. Any insight on this would be greatly appreciated.

The interesting (or not) about this is that the same code runs fine
deploying at Windows in mostly cases, occuring rarely.
If instead of send a update for entirely form sent only for some
components someones of its don't stay consitently. Don't show or hide, the
values stay wrong.
It is a very weird behavior and only occurs on this page, on this component.

The interesting (or not) about this is that the same code runs fine
deploying at Windows in mostly cases, occuring rarely.
If instead of send a update for entirely form sent only for some
components someones of its don't stay consitently. Don't show or hide, the
values stay wrong.
It is a very weird behavior and only occurs on this page, on this component.
Java literals, really constants?
Java literals, really constants?
I see/hear people talking about literals as constants, but are they really
constants?
I think of final as a constant:
final constantNumber = 10;
E.g. in the literal below, I am able to change the value.
int testNumber = 10;
System.out.println(testNumber);
testNumber = 20;
System.out.println(testNumber);

Options for working with two databases in C#
Options for working with two databases in C#
Ok I`m new to C# and new to Programing. I have taken on a small task(goal)
for writing my own program for work.
Basically this program will take two databases. One data base will be
update weekly (lets call this doctor list) and the other data base will be
updated as needed (lets call this employee).
Basically I want to make my program compare the two databases and look for
any matching employees on this list doctor list.
I can figure out the code for the searching and basic stuff.. But I have
no clue where to begin with databases.
I'm ok with SQL but my problem is that my doctor list comes in a dbf file.
I've looked up converting to access and sql but this program needs to be
easy to use for are hr department.
Is there away to write the conversion? (again new to this)
What kind of options do I have with just working with programing it to
read off an excel sheet?
If I do go the access or sql router do the computers this program run off
of need to have access or sql loaded?
I`m not looking for someone to write me the code.. just point me in a good
directions and answer some questions...

Is a given graph a k-plex? (similiar to clique)
Is a given graph a k-plex? (similiar to clique)
My problem is the following:
I need to find an algorithm or at least an idea, how to find out in
efficient time if a given graph is a k-plex.
(Quote: "A k-plex is a maximal subgraph with the following property: each
vertex of the induced subgraph is connected to at least n-k other
vertices, where n is the number of vertices in the induced
subgraph."[http://www.analytictech.com/ucinet/help/1pdb_fw.htm])
Is there anything better than just checking if each node is connected to
n-k other nodes?
I would appreciate any help. Thanks in advance.

Using Python-requests
Using Python-requests
I was trying to access an API using Python-requests.
When I try this:
url = "http://domain.com"
data = {'field': 'project_id', 'op' : 'eq', 'value' : 'some value'}
r = r.requests(url, params=data)
I could get an API response with the project id specified.
But if I try to pass parameters with the same parameters name with
different value, it cancelled out the first params (project_id):
data = {
'field': 'project_id', 'op' : 'eq', 'value' : 'some value',
'field': 'event_type', 'op' : 'eq', 'value' : 'some event_type'
}
I could get an API response with specified event_type only.
API accepts multi-parameters name, but i just dont know how to do it in
python requests.
I would like to know if I am able to do it using python requests or should
I use different one.

Django 1.4: prefect_related with custom model manager and order_by?
Django 1.4: prefect_related with custom model manager and order_by?
This is a long shot question (doesn't seem like it is possible from the
Django docs, but thought I'd ask just to see if anyone has any ideas).
Note: I'm using Django 1.4.
I want to use a custom model manager on a prefetch_related() query. Then,
on top of that, I want to order the prefetched results in a certain way.
To put it in simplified code, I have the following models (note:
Participant model excluded from code because it is irrelevant):
class GoalParticipant(models.Model):
"""Many-to-many model between Goal and Participant models."""
participant = models.ForeignKey(
'Participant', related_name='goal_participants')
goal = models.ForeignKey('Goal', related_name='goal_participants')
active = models.BooleanField(default=True)
class Goal(models.Model):
name = models.CharField(max_length=50)
progress = models.IntegerField()
active = models.BooleanField(default=True)
class Milestone(models.Model):
name = models.CharField(max_length=50)
progress = models.IntegerField()
goal = models.ForeignKey('Goal', related_name='milestones')
active = models.BooleanField(default=True)
From here, my page controller gets a GoalParticipant Id value (called,
say, pid). I want to display all of the goals and milestones for that ID.
So something like this would work normally:
GoalParticipant.objects.filter(participant=pid).select_related(
).prefetch_related('goal__milestones')
Here are the two wrinkles:
1: Custom Model Manager
All of my classes have custom model managers, like this:
objects = ActiveManager()
all_objects = models.Manager()
The ActiveManager runs .filter(active=True) on the queryset. This is for
convenience, so that I can easily just say .objects by default and have
the active filter thrown in. Occasionally, though, I need to display all
of the objects, not just active ones. So I tried this:
GoalParticipant.all_objects.filter(participant=pid).select_related(
).prefetch_related('goal__milestones')
This gives me all of the goal_participants and all of the goals, but still
restricts to only active milestones. Is there a way to force
prefetch_related to use the all_objects model manager?
2: Custom Ordering for Milestones
Users can actually order the goals / milestones by either name or progress
in the UI, and the ordering should be consistent. For example, if the
goals are ordered by progress, the milestones should also be ordered by
progress. So, say I have a var called ordering with the correct ordering,
I could do this:
GoalParticipant.objects.filter(participant=pid).select_related(
).order_by(ordering).prefetch_related('goal__milestones')
This orders the goals correctly, but there does not seem to be any way to
force the milestones to order in the same way. Is there a way to do this?
Thanks in advance for your help and let me know if I can clarify anything.

Jquery.rating.js validate issue on rails
Jquery.rating.js validate issue on rails
Hi there iam making a form in rails that uses jquery.rating.js , im also
using jquery validation plugin .. I just need to make the stars rating
mandatory (10groups of stars from 1 to 5 stars) .. I search on this cause
i thougth there will be tons of topics, but i just could found 1 with my
issue, and it is not marked as correct answer .. Validation for a required
element, jQuery Star Rating
Also i dont think to "ignore" is the best way to validate a field. Im
using this one http://www.fyneworks.com/jquery/star-rating/
Ok in the application_helper.rb i have this
def rate(player, attribute, disabled=false)
rating = ''
rating = rating + label_tag(:attribute,
t("activerecord.attributes.player.#{attribute}") )
for i in 1..5
rating = rating + radio_button_tag("player[#{attribute}]", i,
player.send(attribute) == i ? true : false, :class => "star",
:disabled => disabled)
end
rating = rating
rating.html_safe
end
My Code wich is validating other stuff (i do not now how to set this to
validate he has rated each one of the questions)
Im using Jquery Validate.

Hi there iam making a form in rails that uses jquery.rating.js , im also
using jquery validation plugin .. I just need to make the stars rating
mandatory (10groups of stars from 1 to 5 stars) .. I search on this cause
i thougth there will be tons of topics, but i just could found 1 with my
issue, and it is not marked as correct answer .. Validation for a required
element, jQuery Star Rating
Also i dont think to "ignore" is the best way to validate a field. Im
using this one http://www.fyneworks.com/jquery/star-rating/
Ok in the application_helper.rb i have this
def rate(player, attribute, disabled=false)
rating = ''
rating = rating + label_tag(:attribute,
t("activerecord.attributes.player.#{attribute}") )
for i in 1..5
rating = rating + radio_button_tag("player[#{attribute}]", i,
player.send(attribute) == i ? true : false, :class => "star",
:disabled => disabled)
end
rating = rating
rating.html_safe
end
My Code wich is validating other stuff (i do not now how to set this to
validate he has rated each one of the questions)
Im using Jquery Validate.
<%= javascript_tag do %>
window.onload = function() {
// validate signup form on keyup and submit
$(".edit_player").validate({ // initialize the plugin
errorElement: 'div'});
$("#player_name").rules("add", { required: true, minlength:2, messages: {
required: "<%= t('generales.camporequerido') %>", minlength: "Mínimo 2
caracteres"}});
$("#player_lastname").rules("add", { required: true, minlength:2,
messages: { required: "<%= t('generales.camporequerido') %>", minlength:
"uh minlength?"}});
$("#player_birthday_1i").rules("add", { required: true, messages: {
required: "<%= t('generales.camporequerido') %>"}});

$("#files").rules("add", { required: true, messages: { required: "<%=

};
