setcontext always starts from function line
I am implementing a userthread library. When I try to swap the context
when the yield is called, the swapped function is always starting from the
first line. The program counter is not updated I guess. For Example,
consider there are two Threads, say
T1: {
printf("Inside T1. Yielding to Other \n");
ThreadYield();
MyThreadExit();
}
T2: {
ThreadCreate(t1, 0);
printf("Inside T2. Yielding to Other \n");
ThreadYield();
}
In this case, when I use the setcontext/swapcontext, always the thread
starts from the line 1. So many threads are created and it goes to a
infinite loop. Can anyone tell me what is going wrong

Java Comparator compareToIgnoreCase
Java Comparator compareToIgnoreCase
I am trying to sort an array of strings using compareToIgnoreCase.
The string contain names ex: Billy Jean
When I try to compare them I get a null pointer exception. I think this is
because of the space between the first and last name. How can I compare
whole name?
Thanks
class CompareStudentNames implements Comparator{
//Sorts the students by name ignoring case.
@Override
public int compare(Object o1, Object o2) {
String name1 = ((Student)o1).getName();
String name2 = ((Student)o2).getName();
return (name1.compareToIgnoreCase(name2));
}
}

Generating a dynamic 3D matrix
Generating a dynamic 3D matrix
I need to generate dynamically a 3D matrix like this:
float vCube[8][3] = {
{1.0f, -1.0f, -1.0f}, {1.0f, -1.0f, 1.0f},
{-1.0f, -1.0f, 1.0f}, {-1.0f, -1.0f, -1.0f},
{1.0f, -1.0f, -1.0f}, {1.0f, 1.0f, 1.0f},
{-1.0f, 1.0f, 1.0f}, {-1.0f, 1.0f, -1.0f}
};
I mean, to take a value and put it inside the matrix on running time. I
tried to make a pointer to float, then adding 3D elements by new, but the
results were not what I want.
Note that I don't want to use STL like vector and so on, just a plane matrix.

I'm working on a Python Autocomplete/Code-complete system. I'm already
able to parse my own source files with import ast to access my own defined
classes + functions.
Now I'd like to know, how to access the signatures of system-classes,
functions, constants etc..
How am I able to access this information? Is it also possible with
python's ast module?

I have a WebView that I want to add my own back button to, The webview is
one that has been set up specifically for viewing pdfs in app. I have
added the button and it works but I am unable to resize it or move it
around the screen, and as a result the pdf controls are underneath the
button and unusable. The button layout parameters seem to be something
along these lines (this is not in the code anywhere this is just what it
appears to be )

android:layout_height="wrap_content"
android:layout_alignParentTop="true"

As you can see; the ad, play button, seekbar are all pushed up along with

WP8 check SQL Azure values and perform task
I have a plan to set up a SQL Azure database and then let my windows phone
application check some values and then if the values are good the perform
a task in the application.
My thought is that I have a database containing firstname, lastname,
signature, code1 and code2. In my application I sign in with
first,lastname and signature. Here I am thinking that the app will check
the database for first and last name and signature.
Then if firstname, lastname and a signature is a match then it get the
code1 and code2 and save it in isolated storage to be used on some needed
places in the app.

Readable row key cassandra
Readable row key cassandra
We are investigating migrating a system from a RDBMS to Cassandra and are
having trouble finding a way to convert auto-increment column to
Cassandra. We actually have no need for this to be sequential at all, it
can even contain characters, but it must be short (ideally under 8 chars)
and globally unique. Ideal value would look something like
AB123456
First part of the question is should we be generating this key in
application code or in Cassandra?
Second part: If Cassandra, how?
If Application code, is it an acceptable pattern to generate a candidate
code then attempt an insert, if collision occurs then regenerate key
candidate and retry?

InputStreamReader don't limit returned length
InputStreamReader don't limit returned length
I am working on learning Java and am going through the examples on the
Android website. I am getting remote contents of an XML file. I am able to
get the contents of the file, but then I need to convert the InputStream
into a String.
public String readIt(InputStream stream, int len) throws IOException,
UnsupportedEncodingException {
InputStreamReader reader = null;
reader = new InputStreamReader(stream, "UTF-8");
char[] buffer = new char[len];
reader.read(buffer);
return new String(buffer);
}
The issue I am having is I don't want the string to be limited by the len
var. But, I don't know java well enough to know how to change this.
How can I create the char without a length?

Collection property not properly added to parent on save
Collection property not properly added to parent on save
Look at the following code example.
What it does:
Iterates a bunch of customers. If it already knows the customer, it
retrieves the existing database object for that customer (this is the
problem-ridden part). Otherwise, it creates a new object (this works
fine).
All loans where the social security number matches (CPR) will be added to
the new or existing customer.
The problem: it works for new customer objects, but when I retrieve an
existing customer object, the loans lose their relation to the customer
when saved (CustomerID = null). They are still saved to the database.
Any ideas?

Look at the following code example.
What it does:
Iterates a bunch of customers. If it already knows the customer, it
retrieves the existing database object for that customer (this is the
problem-ridden part). Otherwise, it creates a new object (this works
fine).
All loans where the social security number matches (CPR) will be added to
the new or existing customer.
The problem: it works for new customer objects, but when I retrieve an
existing customer object, the loans lose their relation to the customer
when saved (CustomerID = null). They are still saved to the database.
Any ideas?

Console.WriteLine(" Starting the customer build.");

var numbersToProcess = distincts.Count();
Console.WriteLine(" Identified " + numbersToProcess + " customers. "
+ (DateTime.Now - sTime).TotalSeconds);
foreach (var item in distincts)
{
var loans = from c in db.IntermediaryRkos
where c.CPR == item
select c;
var existing = db.Customers.Where(x => x.CPR ==
item).FirstOrDefault();
if (existing != null)
{
this.GenerateLoanListFor(existing, loans);
db.Entry(existing).State = System.Data.EntityState.Modified;
}
else

var customer = new Customer
{
CPR = item,
};

db.Customers.Add(customer);

Combo box binding in mvvm
Combo box binding in mvvm
I am not able to find out Why is combo box binding not working?
I have a view model which looks like (2 properties)
public ProcessMaintenanceDataObject CurrentProcess
{
get
{
return _CurrentProcess;
}
set
{
_CurrentProcess = value;
OnPropertyChanged("CurrentProcess");
}
}
public ProcessMaintenanceCollection Processes
{
get
{
return _Processes;
}
set
{
_Processes = value;
OnPropertyChanged("Processes");
}
}
public FolderCollection Folders
{
get
{
return _folders;
}
set
{
_folders = value;
OnPropertyChanged("Folders");
}
}
The following is the ProcessMaintenanceDataObject definition
[DataMember]
public string ProcessName
{
get
{
return _ProcessName;
}
set
{
_ProcessName = value;
OnPropertyChanged("ProcessName");
}
}
[DataMember]
public string Id
{
get
{
return _Id;
}
set
{
_Id = value;
OnPropertyChanged("Id");
}
}
[DataMember]
public string FolderId
{
get
{
return _FolderId;
}
set
{
_FolderId = value;
OnPropertyChanged("FolderId");
}
}
[DataMember]
public FolderInfo Folder
{
get
{
return _Folder;
}
set
{
_Folder = value;
if (_Folder != null)
FolderId = _Folder.FolderId;
OnPropertyChanged("Folder");
}
}
The FolderInfo class has FolderName and FolderId Property.
I have a method in viewmodel which fills the Processes. In my view I have
structure something like, I have a treeview which will be bound to
Processes and while selecting any of the item from the treeview, i need to
allow user to edit that entity.
I the view the combo box binding is as:
<ComboBox ItemsSource="{Binding Path=Folders, Mode=OneWay}"
DisplayMemberPath="FolderName"
SelectedItem="{Binding Source={StaticResource viewModel},
Path=CurrentProcess.Folder, Mode=TwoWay}">
...
This binding doesn't work I mean when I select any object from the tree it
fills other information like ProcesName in the textBox but it doesn't make
the Folder object as the selected item in combobox, however the combo box
will be filled.
Any suggestion.

Specific URL If statement in PHP
Specific URL If statement in PHP
I'm trying to add an if statement that only executes the mobile redirect
in this wordpress plugin if the url equals a certain location. I assume it
would be placed in the location that determines whether or not the browser
is mobile or not. I've tried a few different pieces of code with no
success. Any help would be much appreciated.

Capture rate issue and video rendering of silent audio frames
Capture rate issue and video rendering of silent audio frames
I'm new to video processing and I'm having a hard time with it. In my
application, an animation that lasts 8 seconds (more precisely, the video
contains 262 frames) should be mixed frame by frame (via OpenCV) with a
video recorded by the user (code snippets below).
The animation runs at 30 frames per second (the FrameGrabber for the
animation has a frame rate of 29.97002997002997 fps). Both the
MediaRecorder (that records the user video) and the FFmpegFrameRecorder
(that composes the animation with the user video) are set to run at 30fps
(MediaRecorder.setCaptureRate(30), FFmpegFrameRecorder.setFrameRate(30)).
As investigated by a call to
Camera.getParameters().getSupportedPreviewFpsRange(), the front camera of
my Samsung Galaxy S3 supports a range of 5-31 fps.
After the user video is ready, I check the frame rate of the FrameGrabber
for that recording (FrameGrabber.getFrameRate()), which returns 30. But
the MediaRecorder seems to work at around 15 fps: at least twice as much
time has to be recorded so as to keep the audio from the animation running
as expected, without being silenced at the end of the resulting video.
Because my MediaRecorder setting is not working and the Camera does not
support 60 fps, a workaround was inserted in the recording phase: now the
user has to record at least 16 seconds to produce around the same amount
of frames contained in the animation file. That works, but I feel there is
something wrong with this. I wonder if Camera resolution has a role in all
this, too (the animation will always be 720x480), and I have printed some
values about picture sizes supported, dimension setting for pictures and
preview pictures, info about preview size. I tried to dynamically change
resolution, but it didn't work out well, few configuration options from
CamcorderProfile, used to set the MediaRecorder (nothing exactly like
720x480, the best was to do:
MediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_720P))
).
The big problem is to discover how to include silent audio frames in the
beginning of the user video, because that animation will have to start not
in the beginning of the final video, but a few seconds later. I see
FFmpegFrameRecorder does not record a null Frame, not trivial.
I will appreciate any clue. Thank you!

finding sequences from small length sequences
finding sequences from small length sequences
I want to generate a space by using some events in a specific format. Let
me explain the problem on a small example.
Assume that I have the events a,b,c,d,e,f. I will have 3-length sequences
as an input consisting of these events. From these sequences I want to
generate 6-length (number of events) sequences and there will be no
repeated elements in the sequence, i.e. every event will be used exactly
once. 6-length sequences need to satisfy some rules.(explained on example)
Example:
Input:
list1:['a','b','c']
list2:['c','d','e']
list3:['b','c','d']
list4:['a','c','g']
list5:['f','g','e']
List1 describes that, b and c will come after a, and c will come after b
in the 6-length sequence, i.e, when the order changes sequence also
changes. In the same manner List2 describes that d and e will come after
c, and e will come after d. All of the lists will be taken and rules are
recorded. After all rules extracted from these sequences, I need to
generate 6-length sequence that obeys rules. As an example;
Lets say in our case(for simplicity) inputs are List1,List2 and List3
Input:
list1:['a','b','c']
list2:['c','d','e']
list3:['b','c','d']
Then some results for these lists are;
['a','b','c','d','e']: it obeys all of the rules from extracted these 3
lists, like b and c comes after a, d and e comes after c, c and d comes
after b. Ýmportant note from here, if c needs to come after a, they do not
need to be adjacent in the output sequence(6-length)
It is not guaranteed that 6-length sequence will always exist. Firstly, it
needs to be checked that there is at least one such sequence. If not,
algorithm should return false. As an example; lets assume our inputs are
Lis1, Lis2, Lis3, Lis4 and Lis5.
Input:
list1:['a','b','c']
list2:['c','d','e']
list3:['b','c','d']
list4:['a','c','g']
list5:['e','g','b']
a => b => c => g => b it is not possible since b can not come after itself.
I need an algorithm to generate these sequences in Python. I do not have
any code for now, because so far I could not think any efficient
algorithm. It needs to be very efficient in finding longer length
sequences, too.
If the question is not clear, please let me now.

profiling tools for mvc app with very high cpu
profiling tools for mvc app with very high cpu
I am currently running an asp.net mvc application and under high load I am
seeing the site maxing out at 100%. This should not be the case and I
believe there may be an issue with the application that is degrading
performance. This application communicates directly to wcf services layer
which communicates to a sql server database. Neither the wcf layer or
database layer have any performance issues as the 100% CPU can be directly
apportioned to the MVC app.
Therefore I am looking at profiling where the issue may be in the MVC app
- preferably without changing any code. The server is a windows server
2008 R2 with IIS 7.5.
What tools are available to be to assist with this? For starters I have
been looking setting some performance counters.

Stay on the same page after edit
Stay on the same page after edit
I'm trying to follow the RailsTutorial guide, but by doing my own
application instead. I have trouble with section 7, with the forms.
My controller :
def update
d = Deck.find(params[:id])
d.title = params[:deck][:title]
d.slug = params[:deck][:slug]
d.category = params[:deck][:category]
if d.save
redirect_to deck_path(d), notice: "Deck saved successfully"
else
render :edit
end
end
I know it's very, very far from good code, but I will refactor it later
(if you have a suggestion I'm all ears, but I use Rails 3, so I guess the
strong parameters of Rails 4 are out).
The problem is when the d.save does not work (due to validation), with the
render :edit.
Right now, when I enter invalid data, it tries to redirect to the show
action, and crashes because it does not have any data to display.
If I add @deck = d above the render, it works, but the url still is the
show action.
If my validation fail, how can I stay on the same URL and display my error
messages ? Is the "change URL but render the same page" behavior accepted
as valid ?
Thanks !

How to connect MySQL with C# 2008?
How to connect MySQL with C# 2008?
I have Visual studio 2008 express edition and MySQL server 5.5 installed
on my machine. When I try to connect MySQL using server explorer, I could
not get MySQL database in list of datasource. Then I installed MySQL
connector. Now I am getting Oracle listed as a datasource. But when I
connect using Oracle as a data source, I get an error saying : 8.1.7 or
higher version of Oracle client required. Do I need to install MySQL
workbench as well?
Please let me know if any way is available to connect MySQL with C# 2008 ?

Returning count of child in json.rabl
Returning count of child in json.rabl
I have a Location model that I render in json format using Rabl. My
index.json.rabl looks that way :
object false
collection @locations
attributes :id, :name, :address, :rating
:rating is an integer calculated from records in the Rating model (a
Location has_many Rating, a Rating belongs_to a Location). But now I would
like to retrieve also in the Rabl file the number of line of the Rating
model used to calculate this value.
I tried :
child :ratings do
attributes :count
end
and
node(:ratings_count) { |m| @ratings.count }
But obviously it doesn't work... Could anyone help me there ?
Thanks !

Logic challenge: sorting arrays alphabetically in C
Logic challenge: sorting arrays alphabetically in C
I'm new to programming, currently learning C. I've been working at this
problem for a week now, and I just can't seem to get the logic straight.
This is straight from the book I'm using:
Build a program that uses an array of strings to store the following names:
- "Florida" - "Oregon" - "Califoria" - "Georgia"
Using the preceding array of strings, write your own sort() function to
display each state's name in alphabetical order using the strcmp()
function.
Should I do nested for loops, like strcmp(string[x], string[y])...? I've
hacked and hacked away. I just can't wrap my head around the algorithm
required to solve this even somewhat efficiently. Help MUCH appreciated!!!

Pentaho Report with Kettle as Data source
Pentaho Report with Kettle as Data source
I am trying to call a kettle transformation using a pentaho report. My
transformation will retrieve a resultset from table based on a command
line argument. The report generates the correct output if i remove the
command line argument from the ktr and run the hard coded SELECT sql. but
it retrieves empty when we pass command line arguments/parameters.
The report works good when i click preview with arguments, but not working
after i publish it.
My parameters are not getting passed to the kettle transformation.
Report Parameter: ondate Kettle Named parameter: ONDATE (I have mapped
both in my report)
did i miss something?

Multi-monitor: spaces thumbnails on external monitor missing
Multi-monitor: spaces thumbnails on external monitor missing
I've been having the following issue since about two weeks:
My external monitor, containing the OS X title bar, does not show the
thumbnails for my three spaces when in mission control. My retina's
monitor (secondary) does show them as before.
[ Nice, this question need a screenshot, but I don't have enough
reputation. :( ]
External (primary) monitor:
No grey border in mission control. The outermost bg is the wallpaper for
that space on the Retina display. It will change as well when moving to
another space using ^left/^right
I can still move an app to another space by drag 'n dropping them to the
place where the thumbnail should be. So it's not that they're gone;
they're just invisible!
Retina display (secondary)
As it should be in mission control: Zoomed out bg image, grey border
containing three thumbnails for the three spaces I have.
Has anyone experienced these symptoms as well?

Titanium SDK: The Google Play services resources were not found
Titanium SDK: The Google Play services resources were not found
I'm currently working on getting an old Titanium SDK 1.x app working in
the modern era on Titanium SDK 3.1.2. One of the challenges I've managed
to find myself stuck on is after upgrading from Google Android Maps API v1
to v2 I'm consistently getting this error:
The Google Play services resources were not found. Check your project
configuration to ensure that the resources are included.
I have installed in the ADK the 18.0.1 build tools as well as the required
Google Play Services extras package. Uninstalling/reinstalling does
nothing useful, and as far as I can tell there's no way to manually
include the Play Store Services library in Titanium.
For reference I followed the instructions here to set up the Maps API v2
in the app. The following is what is in my tiapp.xml file (I replaced the
actual package names):
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

stability of a linear system
stability of a linear system
The linear system:
$y''(t)+4y'(t)=4(\lambda -1)y(t)+z(t)$
$z'(t)=(\lambda -3)z(t)$
Determine the stability of the system as a function of the parameter
$\lambda\in\mathbb{R}$.
How do i get started on this exercise? I am not asking for the solution,
just anything that can help me on my way?
Should i rewrite the system as a system of first order equations? If so,
how can i do this?

LINQ GroupBy() only if true
LINQ GroupBy() only if true
I need to group data using a custom condition, which returns true or
false. The complexity is, I need to group only the items which return true
and do not group the others.
If I use:
var result = data.GroupBy(d => new { Condition = d.SomeValue > 1 });
all the items get grouped by true/false.
Now I have this statement that works:
var result = data.GroupBy(d => new { Condition = d.SomeValue > 1 ? "true"
: FunctionToGetUniqueString() });
UPDATE: Note, the other items (which are false) must also be in the
grouping, but go separately (one per group).
But I think it is a bit dirty solution, so I though that maybe there is
something more elegant?

I'm working on a a swing application, to handle the data I chose Hibernate
because of its performance. now that I did 80% of the work. I found out
that the application is too slow, like forever waiting. I googled it and
found that if there are many data Hibernate is not the best choice. I
didn't know that and the problem is that my database is complicated many
associations, joins , sets ... I don't have the time to start all over
again ! Help please

Taining LIBSVM with time series data
Taining LIBSVM with time series data
I am working time series problem for several months and still unable to
figure it. Here is the question. I have data collected for 6 days, and the
collection starts from 8:00 am to 11:00. So the data looks something like
this
var1 | var2 | var3
1 2.2 UT1
2 3 UT2
3 1.2 UT3
1 2.2 UT4
2 3 UT5
3 1.2 UT6
1 2.2 UT7
2 3 UT8
3 1.2 UT9
UT represents unixtimestamp. So I converted the var3 into tow columns day
and time. So now the table looks like this
var1 | var2 | var3 | var4
1 2.2 12 8.0
2 3 12 8.25
3 1.2 12 8.5
1 2.2 13 8.0
2 3 13 8.25
3 1.2 13 8.5
1 2.2 14 8.0
2 3 14 8.25
3 1.2 14 8.5
var3 is the day of the month I collected the data and I collected the data
for 6days from 12 to 17. and var4 is time which I collected starting from
8:00 to 11:00 AM for every 20 minutes. The output I am having is a
dependent variable on these variables. So if I need to perform regression
using LIBSVM how can I do that with these?? Do I need to input var3 and
var4 differently? or how does LIBSVM treat this data? DO I need to
normalize the data? I would really appreciate your help.

How to select a TabItem based off of it's Header
How to select a TabItem based off of it's Header
In my program I have a tabItem that gets selected when a TreeViewItem with
an equivalent header is selected.
This is what I currently have (It works):
(parent_TreeViewItem.Items.Contains(SelectedItem))
{
tabControl1.SelectedItem = tabControl1.Items //Changes tab
according to TreeView
.OfType<TabItem>().SingleOrDefault(n =>
n.Header.ToString() == SelectedItem.Header.ToString());
}
The difference with what I'm doing this time is that the tabItem's header
that I'm selecting is composed of a string and an integer.
For example: The TreeViewItem selected will always have a header named
"Arrival", but the tabItem's header will have a form like "Arrival" +
integer. The integer value will come from the parent node's header.
For this process I'm thinking that I'll first need to get the header value
of the parent node, since it contains that integer value I need. Then I'll
need to modify my code above in someway to query for a node with a header
like, "Arrival" + parentHeader.
How would I do something like this?
Thank you.

$("#table").load("tablerefresh");
});
My problem is that when I check/uncheck a box, the table will refresh only

everywhere and can't seem to find a solution. Any ideas?

i want to download a file using extjs 4.1.
The file name is "wsnDataModel.xml".
I've tryed with all things suggested in other posts:
//function invoked clicking a button
DwDataModel : function(th, h, items) {
//direct method that build in file in the location calculated below
with "certurl" (I've verified)
Utility.GetDataModel(function(e, z, x) {
if (z.message) {
//the server method should give an error message
Ext.create('AM.view.notification.toast', {
title : 'Error',
html : z.message,
isError : true
}).show();
} else {
// navigate to get data
var certurl = 'http://' + window.location.host
+ '/AdminConsole3/' + e;
Ext.Ajax.request({
method : 'GET',
url : 'http://' + window.location.host
+ '/AdminConsole3/' + e,
success : function(response, opts) {
//the following navigate and openthe file in the current browser page.
//I don't want to change the current browser page
//window.location.href = certurl;
//the same behaviour with
//document.location = certurl;
//and this don't work at all
window.open(certurl,'download');
},
failure : function(response, opts) {
console
.log('server-side failure with status
code '
+ response.status);
console.log('tried to fetch ' + url);

Is it Better practice to Declare individual objects or loop Annonymous objects into ArrayList?
Is it Better practice to Declare individual objects or loop Annonymous
objects into ArrayList?
I am learning programming with Java through a textbook. A programming
exercise asks you to:
(Swing common features) Display a frame that contains six labels. Set the
background of the labels to white. Set the foreground of the labels to
black, blue, cyan, green, magenta, and orange, respectively, as shown in
Figure 12.28a. Set the border of each label to a line border with the
color yellow. Set the font of each label to Times Roman, bold, and 20
pixels. Set the text and tool tip text of each label to the name of its
foreground color.
I have two answers to the problem. My answer and the books answer. Both
answers work fine.
I use an Array and populate it with anonymous objects by using a loop (as
shown in class Sixlabels extends JFrame{}):
import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;
public class TWELVE_point_8 {
public static void main(String[] args) {
JFrame frame = new SixLabels();
frame.setTitle("Six Labels");
frame.setSize(300, 200);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
class SixLabels extends JFrame {
public SixLabels() {
setLayout(new GridLayout(2, 3));
JLabel[] list = {
new JLabel("Black"),
new JLabel("Blue"),
new JLabel("Cyan"),
new JLabel("Green"),
new JLabel("Magenta"),
new JLabel("Orange")};
// set foreground colors
list[0].setForeground(Color.black);
list[1].setForeground(Color.blue);
list[2].setForeground(Color.cyan);
list[3].setForeground(Color.green);
list[4].setForeground(Color.magenta);
list[5].setForeground(Color.orange);
// set background colors
for (int i = 0; i < list.length; i++)
list[i].setBackground(Color.white);
// set fonts
Font font = new Font("TimesRoman", Font.BOLD, 20);
for (int i = 0; i < list.length; i++)
list[i].setFont(font);
// set borders
Border lineBorder = new LineBorder(Color.yellow, 1);
for (int i = 0; i < list.length; i++)
list[i].setBorder(lineBorder);
// set tooltip
for (int i = 0; i < list.length; i++)
list[i].setToolTipText(list[i].getText());
// add all labels to container
for (int i = 0; i < list.length; i++)
add(list[i]);
}
}
And the book answer does not use an array list (as shown in public
Exercise12_8 extends JFrame{});:
import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;
public class Exercise12_8 extends JFrame {
private JLabel jlblBlack = new JLabel("black");

}
My question is: is it better practice to declare the JLabel object
individually (as the book has) or to populate the Array (or ArrayList)
annonymously as I have? The only benefit I see in doing it the book's way
is readability and having a variable name (which may be used in future
programs, but not in this particular one).

Fastest way to determine the lowest available key in JAVA HashMap?
Fastest way to determine the lowest available key in JAVA HashMap?
Imagine a situation like this: I have a HashMap<Integer, String>, in which
I store the connected clients. It is HashMap, because the order does not
matter and I need speed. It looks like this:
{
3: "John",
528: "Bob",
712: "Sue"
}
Most of the clients disconnected, so this is why I have the large gap. If
I want to add a new client, I need a key and obviously the usage of
_map.size() to get a key is incorrect.
So, currently I use this function to get he lowest available key:
private int lowestAvailableKey(HashMap<?, ?> _map) {
if (_map.isEmpty() == false) {
for (int i = 0; i <= _map.size(); i++) {
if (_map.containsKey(i) == false) {
return i;
}
}
}
return 0;
}
In some cases, this is really slow. Is there any faster or more
professional way to get the lowest free key of a HashMap?

C# How to Keep User From leaving Program in Windows
I'm writing a full-screen program for children (using C# and WinForms),
and it is important that they (the users) are not able to move the mouse
around and end up in another program in Windows or on the desktop -- in
other words, once the teacher puts this program on the screen, the
children must remain there, and the teacher can only exit the program
using a password).
Is there any way to do this?

im making a simple game on Xcode and i decided to use a nstimer in my .m
xcode found 3 problems with my code it says Assigning to 'CGPoint' (aka
'struct CGPoint') from in compatable 'int' twice and it says use of
undeclared game loop. Any help is great
enter code here

Debugging jQuery Animation
Debugging jQuery Animation
I am using a page flipping plugin called "bookblock" (demo can be found
here).
I have put images on each page, which I am adding dynamically. The problem
is when I flip the page, the previous and next divs are suddenly squished
together on each side of the book. The following screenshot is taken
mid-animation of a page flip.
As you can see each page in the book is "item1", "item2", etc. All of the
display properties are set to "none", but for some reason they can be
seen.
A live version of this site can be found here. I have tried adding
$(".bb-item").hide();
Right before the animation sequence, which appears to begin on line 259 of
js/jquery.bookblock.js, but no luck. How else could I go about debugging
this problem?
UPDATE: I am very sorry, I should have mentioned that you can access the
flipbook by clicking on the "expand" icon, in the bottom right of each
div.

How do I track who uses my Excel spreadsheet?
How do I track who uses my Excel spreadsheet?
I created an Excel spreadsheet that my boss wants to put on the company's
internal website. The spreadsheet contains some seldom-used, esoteric, but
handy functions that only certain employees within the company will find
really useful.
The problem is that I don't know who the future users are, and my boss
wants me to identify who uses my spreadsheet.
He asked that I password-protect the Excel spreadsheet in such a way that
one password does NOT unlock all of the copies that people can download
from the site. For example, I can't just make the password "stackoverflow"
because once a user legitimately gets the password from me, and is shared
with other people, it can be used by anyone within the company to unlock
all subsequently downloaded spreadsheets. I will never be able to
ascertain who is using the spreadsheet. Also, I cannot modify the website,
so I hope to achieve this tracking of users through Excel and email.
Is there a way to have Excel randomly generate a string, which the user
emails me, and then I respond with the appropriate password that will
unlock the file (based off the generated string)? This requires the user
to check in with me before using the spreadsheet (the ideal situation).
Is such an arrangement possible in Excel 2010 Professional Plus?

Pull from Heroku to my computer (mac)
Pull from Heroku to my computer (mac)
I am very new to Rails, Heroku, Github and all the other stuff. My problem
is that locally on my Mac and unfortunately on Github i do have a "bad"
version of the application. Luckily i didn´t push it to Heroku. So on
Heroku i do have a good version of my application. Since i spend days
trying to find a bug in my application and got very upset, i want to go
the easy way and download the Heroku version to my Mac and replace the bad
one. And afterwards push it to Github. So that somehow possible? Already
tried $ git pull heroku master and got this error Your key with
fingerprint .... is not authorized to access myapp.
Getting really upset here. Haha. Thanks for the help in advance.

is that locally on my Mac and unfortunately on Github i do have a "bad"
version of the application. Luckily i didn´t push it to Heroku. So on
Heroku i do have a good version of my application. Since i spend days
trying to find a bug in my application and got very upset, i want to go
the easy way and download the Heroku version to my Mac and replace the bad
one. And afterwards push it to Github. So that somehow possible? Already
tried $ git pull heroku master and got this error Your key with
fingerprint .... is not authorized to access myapp.
Getting really upset here. Haha. Thanks for the help in advance.
Qt 5 - How to send data back from child dialog in real time
Qt 5 - How to send data back from child dialog in real time
I have a settings dialog that has some settings that require another
dialog to fully configure. My window shows a preview of the data as it's
being tweaked by these settings. Upon clicking on the configuration button
I launch another modal dialog with some knobs to twist to fine tune the
particular setting.
I wish to send the result of the twisting of the knobs on the child dialog
back to the parent dialog so that it can show the new preview data as the
knobs on the child are being played with. The way I imagine it is I have a
"refresh preview" function in the parent that is called after modification
of it's data preview member variables. The question is, how do I do this?
How can I access getters/setters from the parent dialog as a modal child
dialog? If I do access them will the preview change or will it be blocked
because of the modality of the child?
Thank you!

CORS XMLHTTPRequest not working in Chromium 28
CORS XMLHTTPRequest not working in Chromium 28
I am trying to send CORS Ajax requests but it seems to fail :
var xhr = new XMLHttpRequest();
xhr.open("GET", "http://enable-cors.org");
xhr.addEventListener("load", function() { console.log(this.response); });
xhr.withCredentials = true;
xhr.send();
I am making this request from the console, while browsing html5rocks.com.
I get this error message :
XMLHttpRequest cannot load http://enable-cors.org/. Origin
http://www.html5rocks.com is not allowed by Access-Control-Allow-Origin.
I believe enable-cors.org should send back correct
Access-Control-Allow-Origin headers :) But this holds true for any other
website. Also the console tells me an Origin header has been properly sent
in my request. What do I do wrong ?

Auto Increment Id in stored procedure not working
Auto Increment Id in stored procedure not working
I am trying to get company id like "Cp-00001". If data exists in table
then the id should be "Cp-00001" + 1 = "Cp=00002" and do on...
Here's what I have so far:
CREATE PROCEDURE [dbo].[sp_AutoGenerateCustomerCode]
AS
DECLARE @id VARCHAR(10)
BEGIN
SELECT @id = 'Cp-' + CAST(MAX(CAST(SUBSTRING(CompanyCode,4,5) AS
INTEGER))+1 AS VARCHAR) FROM [Beauty Saloon
Project].[dbo].[tbl_Company];
IF @id IS NULL
BEGIN
SET @id = 'Cp-00001';
END
RETURN @id;
END
but when i call it here
datatable DT = new datatable
DT = ExecuteSpDataTable("sp_AutoGenerateCustomerCode");
This returns null.
If I don't have data then it should return Cp-00001, but I have one data
row in which company code is saloon is it the reason for null ???

Unix: how to read line's original content from file
Unix: how to read line's original content from file
I have a data file, the content is as follows:
department: customer service section: A
department: marketing section: A
department: finance section: A
When I read each line, I would extract the department name using cut
command. Unfortunately, the program will automatically trim all redundant
space and thus I cut the department name incorrectly.
cat dept.dat | while read line
do
echo $line
echo $line | cut -c 12-29
done
e.g. the original line is:
department: marketing section: A
While the program treats this line as:
department: marketing section: A
How can I read the line without trimming all the redundant space?

ContentProvider, multi-tables and the correct OOP code (good practice)
ContentProvider, multi-tables and the correct OOP code (good practice)
I thought much time wondering how to constract ContentProvider class to be
convenient working with many tables (about 10 tables and 60
methods:delete, query, insert..) because I didn't want to have them all in
1 method (delete, query, insert) with 1 switch clause. So I use this
patern, for example:
in ContentProvider class:
public int delete(Uri uri, String where, String[] whereArgs) {
switch (sUriMatcher.match(uri)) {
SQLiteDatabase db = mOpenHelper.getWritableDatabase();
...
switch (sUriMatcher.match(uri)) {
...
case EXAMPLE_ID:
id = Integer.parseInt(uri.getPathSegments().get(1));
count = tblExample.deleteRaw(db, id);
break;
default:
throw new IllegalArgumentException("Unknown URI " + uri);
}
getContext().getContentResolver().notifyChange(uri, null);
return count;
}
I constract 1 class for each table, where I wrote static methods, which I
call from ContentProvider class, they are like this (each method much more
complex in reality):
public class tblExample {
public static final Uri CONTENT_URI = Uri.parse("content://" +
DBContentProvider.AUTHORITY + "/example");
public static final String KEY_ROWID = "_id";
public static final String ROW_ID_EXAMPLE = "id_example";
...
public static int deleteRaw(SQLiteDatabase mDb, int id_example) {
return mDb.delete("tblExample", tblExample.ROW_ID_EXAMPLE +
" = "+ id_example, null);
}
...
}
I see that this is convenient to use my pattern, but the question is ...
is this not a very ugly code from the point of oop or memory management?
