Photo storage / sort
I'm wondering what the best practice is for photo storage. I'm in the
business of storing photos with a user. Each user can have up to 35 photos
and we currently have around a 100k users. I currently reference the
photo's from a database.
My proposed solution is a hash of the photo name like so.
f56c0de1c61fdb926e79e8a0a65bd12930c9.jpg
broke out into directories like so
Photo 1
f5/6c/0d/e1c61fdb926e79e8a0a65bd12930c9.jpg
f5/6c/0d/e1c61fdb926e79e8a0a65bd12930c9_thumb.jpg
Photo2
ec/1c/55/bfb660548a6770238668c4b117d92f.jpg
ec/1c/55/bfb660548a6770238668c4b117d92f_thumb.jpg
database Stored in the database as a comma separated array like so for
sort ordering.
ec1c55bfb660548a6770238668c4b117d92f,ec1c55bfb660548a6770238668c4b117d92f
Is this the most efficient way to do this? and is it scalable? I'm not
sure if the photo hash is to large and I'm also not sure if the directory
size is correct.
I created a more detailed post over on stackoverflow, just not sure where
this question belongs.

Making XMonad redetect two monitors [migrated]
Making XMonad redetect two monitors [migrated]
I accidentally pressed Meta-Q and xmonad restarted. Now, it has mirrored
the same thing on both of my monitors. How do I get it go back to treating
them as two separate screens?
Things I have tried: - Pressing Meta-Q again - Turning one of the monitors
off and back on
This has happened before, and logging out and back in again worked. But I
don't want to do that every time I accidentally press Meta-Q. This has
started happening since I started using dmenu_run to launch apps.
Previously, Meta-Q would restart xmonad harmlessly (without going into
mirrored mode).

Here is the fiddle, http://jsfiddle.net/zPNk3/5/. The problem is when I
click first time on .pick element the '.palette' element is shown
properly. But when I click next time the same is not working.

How to get a TextView at the bottom of the screen under a listview?
How to get a TextView at the bottom of the screen under a listview?
I'm making a settings screen in my android app. This list of course has a
pre defined set of options (notifications/colors/log out/etc.). So I
decided to create the list statically in xml. Because the list should
equally well display if it has more content than the screen I nested my
LinearLayout within a ScrollView (couldn't use a ListView because I want
to statically define the items in it).
This works fine with the following code now:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/black" >
<TextView
android:layout_width="fill_parent"
android:layout_height="80dp"
android:paddingTop="30dp"
android:text="@string/account_notifications"
android:background="@color/white"
android:layout_marginBottom="1dp"/>
<TextView
android:layout_width="fill_parent"
android:layout_height="80dp"
android:text="@string/colors"
android:background="@color/white"
android:layout_marginBottom="1dp" />
<TextView
android:layout_width="fill_parent"
android:layout_height="80dp"
android:text="@string/log_out"
android:background="@color/white"
android:layout_marginBottom="1dp" />
</LinearLayout>
</ScrollView>
As you can see I set the background of the LinearLayout to black and the
items to white, with a marginBottom of 1dp, so that there is a separator
between the list items. I now want the logout TextView always at the
bottom of the screen. In case there are more items than the screen can
hold, the Logout should simply be situated at the end of the list.
To get the logout to the bottom of the screen I found some solutions in
this SO question. I first use the first suggestion like so:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/black" >
<TextView
android:layout_width="fill_parent"
android:layout_height="@dimen/list_item_height"
android:text="@string/account_notifications"
android:background="@color/white"
android:layout_marginBottom="1dp"/>
<TextView
android:layout_width="fill_parent"
android:layout_height="@dimen/list_item_height"
android:text="@string/colors"
android:background="@color/white"
android:layout_marginBottom="1dp" />
</LinearLayout>
<TextView
android:layout_width="fill_parent"
android:layout_height="@dimen/list_item_height"
android:text="@string/log_out"
android:background="@color/white"
android:layout_marginBottom="1dp"
android:layout_alignParentBottom="true" />
</RelativeLayout>
</ScrollView>
This surprisingly makes the logout TextView totally disappear. So I tried
the second suggestion like so:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/black" >
<TextView
android:layout_width="fill_parent"
android:layout_height="@dimen/list_item_height"
android:layout_weight="1"
android:text="@string/account_notifications"
android:background="@color/white"
android:layout_marginBottom="1dp"/>
<TextView
android:layout_width="fill_parent"
android:layout_height="@dimen/list_item_height"
android:layout_weight="1"
android:text="@string/colors"
android:background="@color/white"
android:layout_marginBottom="1dp" />
<TextView
android:layout_width="fill_parent"
android:layout_height="@dimen/list_item_height"
android:text="@string/log_out"
android:background="@color/white"
android:layout_marginBottom="1dp" />
</LinearLayout>
</ScrollView>
But this unfortunately doesn't do anything either. No clue why not.
So my question, does anybody know how I can get my logout to the bottom of
the screen, or in case the list is to long for the screen, to the bottom
of the list.
All tips are welcome!

Store the line break from textarea , store to database and show on frontend?
Store the line break from textarea , store to database and show on frontend?
Currently I am working on storing textarea paragraph
<textarea rows="10"></textarea>
I can save the whole content but the problem is it does not include line
breaks. I wonder what is the best practice of storing the space/line break
from the textarea to database. Also, I need to prevent the user from
inserting the inside the textarea.
Is it good parctice ?
e.g.
text=replace(text,"/n","<br>")
text=replace(text," "," ")
text=replace(text,"<script>","")
text=replace(text,"</script>","")
Thanks

Boolean value is set to true from the start
Boolean value is set to true from the start
Hey i have been trying to make this work, but i can't figure out what the
problem is.
I want the stopValue to be false when i start the app, and then it is
gonna be set by my actions in the app. I have found out boolean values are
false from the start and therefore my start intent is set to false.
This is not my only problem, when i have entered the start kilometers and
my stop kilometers it give me the stop kilometers only. and the result
should have been start - stop kilometers.
I don't know if these problems have a connection. Maybe i don't get the
sharedpreferences part right or maybe it's the putextra or getIntent part.
Thanks for your time.

Apache: redirect if host doesn't start with www or cdn
Apache: redirect if host doesn't start with www or cdn
My goal is to redirect to domain with www. if both these conditions are met:
current host is not www.example.com
current host is not cdn.example.com
I'm using a .htaccess file with this code, but the second condition is not
honoured:
RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
RewriteCond %{HTTP_HOST} !^cdn\.example\.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
Thank you

PHP using iconv to convert large files
PHP using iconv to convert large files
I need to convert text files' character encodings without hogging the
server's memory, while the input file is user configured and its size
isn't limited.
Would it be more efficient to wrap an unix's iconv command using exec()
(which I'd rather avoid, although I already use it in the application for
other file operations), or should I read the file line by line and output
it into another file?
I'm thinking working this way:
$in = fopen("in.txt", "r");
$out = fopen("out.txt", "w+");
while(($line = fgets($in, 4096)) !== false) {
$converted = iconv($charset["in"], $charset["out"], $line);
fwrite($out, $converted);
}
rename("out.txt", "in.txt");
Is there any better approach to convert the file fast and efficiently? I'm
thinking this might be rather CPU intensive, but then I believe iconv
itself is an expensive task so I'm not sure if I can make it actually not
eat the server much at all.
Thanks!

list of english sentences?
list of english sentences?
I'm making a very weak python ai where the user inputs a sentence and the
computer answers, just a proof of concept type idea, using the Stanford
POST tagger, and I'd like a txt file of a bunch of random sentences to
test it. Random lines from books, wikipedia, etc. it doesn't really
matter, but preferably grammatically correct and sentences that people
actually use.
If anyone knows of such a file that would be awesome.

Implementing CSS in jQuery
Implementing CSS in jQuery
Assuming that one is developing a web application which is sufficiently
non-intensive that overhead is not a concern. Is it reasonable to
implement CSS solely in Javascript/jQuery and completely abandon external
css files?
$('<div/>').attr({'id':'special_box'}).addClass('little_box').appendTo('body')
$('<div/>').addClass('little_box').appendTo('body')
$('<div/>').addClass('little_box').appendTo('body')
...
$('.little_box').css({'color':'red'})
$('#special_box').css({'color':'blue'})
Is there anybody advocating this complete conflation? Is there anything
that completely prevents it or makes it evidently unreasonable?

Capacity of textarea
Capacity of textarea
What is the maximum capacity of a textarea that it can accept some
text.The html page is working fine when the text limits to about 130-140
words.But when the text exceeds that limit it doesn't do anything(just
hangs). This text is passed through javascript for some manipulations and
displayed in another textarea. If there is a limit how to make it accept
large amount of text?

is this linkedlist code a good practice?
is this linkedlist code a good practice?
Hi everyone I am a newbie in C and trying to learn it. I have a simple
query regarding this linkedlist implementation which I found at many
places:
void addNode(node **listhead, int data, int pos){
if(pos<=0 || pos > length(*listhead)+1){
printf("Invalid position provided, there are currently %d
nodes in the list \n", length(*listhead));
return;
}else{
node *current = *listhead;
node *newNode = (node*)malloc(sizeof(node));
if(newNode == NULL){
printf("Memory allocation error\n");
return;
}
newNode->data = data;
newNode->next = NULL;
if (current == NULL){
*listhead = newNode;
return;
}else{
int i = 0;
while(current->next != NULL && i < pos-1){
++i;
current = current->next;
}
if(current->next == NULL){
current->next = newNode;
}
if(i == pos-1){
newNode->next = current->next;
current->next = newNode;
}
}
}
}
int main(){
node *head = NULL;
node **headref = &head;
addNode(headref, 1, 1);
addNode(headref, 2, 2);
addNode(headref, 3, 3);
printList(head);
return 0;
}
my query is here we are creating a pointer to a pointer which is pointing
to NULL. This code works, however I wanted to know if this is a good
practice. If it is not, how should I create my head pointer and pass its
reference to the addNode function.
Hi everyone I am a newbie in C and trying to learn it. I have a simple
query regarding this linkedlist implementation which I found at many
places:
void addNode(node **listhead, int data, int pos){
if(pos<=0 || pos > length(*listhead)+1){
printf("Invalid position provided, there are currently %d
nodes in the list \n", length(*listhead));
return;
}else{
node *current = *listhead;
node *newNode = (node*)malloc(sizeof(node));
if(newNode == NULL){
printf("Memory allocation error\n");
return;
}
newNode->data = data;
newNode->next = NULL;
if (current == NULL){
*listhead = newNode;
return;
}else{
int i = 0;
while(current->next != NULL && i < pos-1){
++i;
current = current->next;
}
if(current->next == NULL){
current->next = newNode;
}
if(i == pos-1){
newNode->next = current->next;
current->next = newNode;
}
}
}
}
int main(){
node *head = NULL;
node **headref = &head;
addNode(headref, 1, 1);
addNode(headref, 2, 2);
addNode(headref, 3, 3);
printList(head);
return 0;
}
my query is here we are creating a pointer to a pointer which is pointing
to NULL. This code works, however I wanted to know if this is a good
practice. If it is not, how should I create my head pointer and pass its
reference to the addNode function.

Python script to copy data from an external drive
Python script to copy data from an external drive
I am in the process of writing a a python program to move user profile
data from an externally attached HD to a new computer. I am currently
having trouble getting the python script to recognize the external drive.
The file path seems accurate, but I am getting an error:
Traceback (most recent call last):
File "C:\Users\Eric\Documents\KoelCopy\KoelCopy.py", line 9, in <module>
distutils.dir_util.copy_tree(source, destination)
File "C:\Python33\lib\distutils\dir_util.py", line 124, in copy_tree
"cannot copy tree '%s': not a directory" % src)
distutils.errors.DistutilsFileError: cannot copy tree 'F:\Users\Nick\My
Documents': not a directory
My code is as follows:
import distutils.core
input_source = input('Enter User Name: ')
source_drive = input('Enter source drive letter: ')
directories = ["\\My Documents", "\\Favorites", "\\Desktop"]
for directory in directories:
source = source_drive + ':\\Users\\' + input_source + directory
destination = 'C:\\Users\\' + input_source + directory
distutils.dir_util.copy_tree(source, destination)
I have also noticed if I get this to work coping from the C drive to C
drive I am getting access denied errors. Would this be caused by windows
security or should I be using a different copy command? I also noticed
when I tested just copying the Desktop is was getting an access denied
error on just the desktop.ini file. How would I exclude such files? I know
I have a lot of questions, I appreciate your time.
Thanks!

How to wrap the jQuery function
How to wrap the jQuery function
Question
I'd like to know the best way I can wrap the jQuery function while
retaining all functionality. Essentially I want to call $('#someId') but
have it operate as $('#' + id + 'someId') by wrapping the function,
modifying the arguments, and passing it through to the original jQuery
function.
Motivation
I have a section of JS that will reuse the same variable winId which is
concatenated and passed to jQuery. Instead of writing
$('#' + winId + 'someId').html();
$('#' + winId + 'someOtherId').css();
...
$('#' + winId + 'someThirdId').text();
throughout the whole file, I want to wrap the jQuery function so I can
just call
$('#someId').html();
$('#someOtherId').css();
...
$('#someThirdId').text();
and and have winId added in before passing through to $.
My attempt
Here's what I'm thinking as a wrapper:
(function(){
var fn = $;
return $ = function(){
for(var i = 0; i < arguments.length; i++){
if(typeof arguments[i] == 'string'){
arguments[i] = /* code to add in winId, omitted */
}
}
return fn.apply(this, arguments);
}
})();
This works great, except that obviously none of the methods like $.ajax
are available:
Uncaught TypeError: Object function (){
for(var i = 0; i < arguments.length; i++){
if(typeof arguments[i] == 'string'){
arguments[i] = /* code to add in winId, omitted */
}
}
return fn.apply(this, arguments);
} has no method 'ajax'
Note: I know I could copy the object over using jQuery.extend($, jQuery),
but I'm interested in a more elegant solution than that if possible.

How to fill an ArrayList from a file while formatting the information at the same time? [on hold]
How to fill an ArrayList from a file while formatting the information at
the same time? [on hold]
I am working on this project here for school and I really am stuck at this
point. Basically I have to take this trivia.txt file that he supplied and
fill an ArrayList with it, that i have somewhat of a clue how to do. But
then I have to format the output so that my program will recognize the
different categories and be able to output them correctly. Here is what he
has written,
"In this assignment you will write an application that simulates a trivia
game. You will be given a text file that contains a set of questions and
answers in six different categories. Your program will select a random
question from each category to be answered by the player. The score will
be displayed at the end of each run.
Input data format: The input file contains questions and answers in
different categories. For each category, the first line indicates the name
of the category. This line will be followed by a number of pairs of lines.
The first line of the pair is the question, and the second line is its
corresponding answer. A blank line separates the categories. Technical
requirements:
„h Create a class called TriviaQuestion that represents a typical question
object.
„h After reading the data, store the information inside ArrayList(s).
„h Be user friendly in your input/output. Ignore cases. Accept partially
correct answers if possible."
Right now as my code will show I am stuck on how to add the info to the
ArrayList in the format that he has specified. I don't want anyone to do
my work for me. I just need nudged in the proper direction. I dont know if
I need many arraylists for each category and if I do, do I need them to be
in seperate classes? This is only my second semester so I'm still pretty
perplexed by these things. There are other jave trivia games online and on
this forum but I can't find any that work in this fashion. Anyway, here is
the code and the text file afterwards....
import java.io.File;

reinitialize an app after reopen it
reinitialize an app after reopen it
I am wondering for a background running app, is there a way to
reinitialize the app (like terminate the app and start the app from the
beginning) when I reopen the app after a long time of suspension? I think
the OS would kill the app when the device is out of memory, so can I do
this manually?

For each rol I get extra queries. I still dont get how hibernate works.
How can I avoid this??
I have a many to many relation with extra columns:
rol 0..* -------- 1..* permission
This are my models:
Rol:
@Table(name = "rol", uniqueConstraints = { @UniqueConstraint(columnNames =
"nombre") })
public class Rol implements Serializable{
@Id
@Column(name = "_id")
private String id;
@Column(name = "nombre")
@NotEmpty
private String nombre;
@Column(name = "descripcion")
private String descripcion;
@Column(name = "status")
private String status;
@NotEmpty
@OneToMany(fetch= FetchType.LAZY, mappedBy = "rolPermiso_pk.rol",
orphanRemoval = true, cascade=CascadeType.ALL)
private Set<Rol_Permiso> permisos = new HashSet<Rol_Permiso>(0);
Permiso:
@Entity
@Table(name = "permiso", uniqueConstraints = {
@UniqueConstraint(columnNames = "nombre") })
public class Permiso implements Serializable {
@Id
@Column(name = "_id")
private String id;
@Column(name = "nombre")
@NotNull
private String nombre;
@Column(name = "descripcion")
private String descripcion;
@Column(name = "status")
private String status;
@OneToMany(fetch = FetchType.LAZY, mappedBy =
"rolPermiso_pk.permiso", cascade = CascadeType.ALL)
private Set<Rol_Permiso> roles = new HashSet<Rol_Permiso>(0);
Rol_Permiso:
@Entity
@Table(name = "rol_permiso")
@AssociationOverrides({
@AssociationOverride(name = "rolPermiso_pk.rol", joinColumns =
@JoinColumn(name = "idRol")),
@AssociationOverride(name = "rolPermiso_pk.permiso", joinColumns =
@JoinColumn(name = "idPermiso"))
})
public class Rol_Permiso implements Serializable{
@EmbeddedId
private Rol_PermisoId rolPermiso_pk = new Rol_PermisoId();
@Column(name = "status")
private String status;
Rol_PermisoId:
@Embeddable
public class Rol_PermisoId implements Serializable{
@ManyToOne
private Rol rol;
@ManyToOne
private Permiso permiso;
Im trying to show a list of roles with their permissions. So I create this
query:
public List<Rol> findAllWithPermissions() {
return mySessionFactory.getCurrentSession().createQuery("select
distinct r from Rol r left join fetch r.permisos").list();
}
And this works, but extra queries are made:

Highcharts - the third line is not displayed properly (jsfiddle included)
Highcharts - the third line is not displayed properly (jsfiddle included)
I have a Highcharts graph that consist of 3 lines - [fiddle here][1]. The
problem is, that the third line (the black one - New York) is not
displayed properly - the points with 0 value are not shown into the graph.
But the zero-points for those 2 previous lines are displayed properly.
Am I missing something or why is the third line incomplete?
Thanks

Interview type questions
Interview type questions
I have an interview coming up, and I was just wondering the easiest way to
explain the following questions:
What is object oriented programming? What is the difference between an
abstract and interface class? Describe an application lifecycle:
I know the "book" definitions, but not like a short interview type answer.
Any help would be appreciated!

Video Overlay for SMPTE 292m
Video Overlay for SMPTE 292m
I'm trying to find a way to add an overlay to SMPTE 292 video as it is
being transmitted.
I've never really worked with video so I'm trying to avoid making
assumptions that will ruin my day in the future.
The system is essentially like this:
A device(let's say a laptop) generates the video and sends it out on a
wire. Another device is connected at the end(a monitor) that shows the
video. The device I'm looking at making will cut into that wire and
attempt to add an overlay to the video. To be clear, I don't have access
to the source device or the receiving device, so I'll just be playing man
in the middle and manipulating the video after it has been sent out.
Now, in my mind the easiest way to do this would be to read in one frame
of the video, add on the overlay, and send the frame out.
Is this an overly naive approach? The things I've read so far seem to
indicate that video is more complicated than that, and I can understand
that on the lowest levels that it can be more complicated, but are there
software libraries that can be used to accomplish this? I'd prefer
libraries for any high level language like C++, Java, C#, etc but it
doesn't really make a difference.
Also, is there better terminology that I can use to learn more about this?
My only search terms right now are video and overlay which are pretty
ambiguous.

assumptions that will ruin my day in the future.
The system is essentially like this:
A device(let's say a laptop) generates the video and sends it out on a
wire. Another device is connected at the end(a monitor) that shows the
video. The device I'm looking at making will cut into that wire and
attempt to add an overlay to the video. To be clear, I don't have access
to the source device or the receiving device, so I'll just be playing man
in the middle and manipulating the video after it has been sent out.
Now, in my mind the easiest way to do this would be to read in one frame
of the video, add on the overlay, and send the frame out.
Is this an overly naive approach? The things I've read so far seem to
indicate that video is more complicated than that, and I can understand
that on the lowest levels that it can be more complicated, but are there
software libraries that can be used to accomplish this? I'd prefer
libraries for any high level language like C++, Java, C#, etc but it
doesn't really make a difference.
Also, is there better terminology that I can use to learn more about this?
My only search terms right now are video and overlay which are pretty
ambiguous.

access 2000, sql server not in dropdown when linking
I have a windows 7 machine with access 2000 installed to support legacy
apps. When I try to link a table "SQL Server" is not shown in the
dropdown. I tried to link through code but the driver isn't present. I
forgot how to fix this. I did a fresh install of Office 2000 selecting
only access. Please help. Thanks

Sleeping thread when using Mono Evaluator
Sleeping thread when using Mono Evaluator
I'm doing on the fly compilation using Mono Evaluator, almost everything
is ok but I'm having an issue with Sleep in side evaluated code.
here is piece of sample code:
public class TestClass
{
public static void TestMethod()
{
System.Threading.Thread.Sleep(5000);
Console.WriteLine("Test finish."));
}
}
and here is the code I'm using to execute C# on the fly using Mono Evaluator:
var reportWriter = new StringWriter();
var consoleReport = new ConsoleReportPrinter(reportWriter);
var context = new CompilerContext(new CompilerSettings(), consoleReport);
var eval = new Evaluator(context);
eval.Run(code);
eval.Run(@"
var output = new System.IO.StringWriter();
Console.SetOut(output);
TestClass.TestMethod();");
Then doing:
string result = (string)eval.Evaluate("output.ToString();");
i'm having in "result" the return of executed code. If I dont use Sleep()
inside executed code, everything is ok. But when I do Sleep() then the
line to get "result" is executed without waiting the 5000 miliseconds.
I'm expecting that the code passed to Evaluator.Run sleep as it is
sleeping inside. why it is not happening ?
How can I achive the wait for executed code finish before evaluate result ??
thanks a lot

I currently have an object with various fields (mostly date fields) as
shown from the console log below. There are more fields than this but all
are similar. Also I am aware that they are all 1970 this is how we set
them on the .net side.

I have a view with a form in holding all the date fields etc etc..
{
xtype: 'datefield',
labelWidth: 50,
name: 'ngDomesticPipework',
fieldLabel: 'NG'
},
All fields have identical names in the model, view and data object but
will not load into my form ready for editing. I am simply getting the form
element with a component query setting the data to be the object I want to
load and calling load record.
var data = record.get('engineer').gasSafeCard;
gasSafeFormCmp.loadRecord(data);
Thanks folks massive help as always.

Prism How to bind Module View to app wide property
Prism How to bind Module View to app wide property
I know this may seem silly but, what is the best way to bind to
Application Wide properties using MVVM and Prism?
Problem: ConnectionStatus Status {...} (Implements INotifyPropertyChanged
etc..)
How do I go about accessing this property in specific modules? I want to
be able to use the Status property across different modules?
What is the best way of getting this data across different modules?
Solutions
Currently I am leaning towards having the following view model in the
infrastructure project (shared across modules)
namespace Project.Infrastructure
{
public class AppViewModel
{
public ConnectionStatus Status {...}
}
}
And in IoC define AppViewModel as Singleton, and pass this in the
constructor of ModuleViewModel
namespace Project.ModuleA
{
AppViewModel _appViewModel;
public class ModuleViewModel
{
public ModuleViewModele(AppViewModel appViewModel)
{
....
}
}
}
Question
Is this the best way to do this or is there a better way of doing this?
E.g.
Using EventAggregator and ConnectionStatusChangeEvent to subscribe and
publish to changes in the connection? But in this case if someone
subscribes to the event after it got pubblished (such as online) they will
not get any starting value, so a IStatusService could be used at the
start?
Using RegionContext and binding that to the Status property in the Shell?
But this seems to defeat the purpose of Shell not knowing what the Modules
use etc..
Or is there something that I have completely missed?
I have read the whole Prism(v4) documentation and just not 100% sure of
which is the best way of implementing this.

How do I apply a function in R to certain columns of a data frame grouped by another column?
How do I apply a function in R to certain columns of a data frame grouped
by another column?
I've been looking at the help page for tapply and by and I'm not sure if
they are the right tool for this. For example, if I have a dataframe where
the columns are Name,Value1,Value2 and I want to apply a function, say
function f(x,y) { do_something } to Value1 and Value2 grouped by Name and
get as a result a dataframe with the columns Name,f(Value1,Value2) how
should I go about that?
I can get tapply to work in a simple case like this:
tapply(df$Name, df$value1, mean)
but what if my function takes as input df$value2 as well? and is not as
simple as mean? In other words, pseudo-notation for what I'm trying to do
would be:
tapply(df$Name, c(df$value1,df$value2), function f(x,y) { x+y+bla...})
by another column?

C++ string/char and accents
C++ string/char and accents
I'm writing a text writer in C++, which I'll have a string of a phrase and
display the appropriate bitmap font for each char value.
For now, it's working for the regular characters, but I'm getting weird
values for accents and other characters such as À, Á, Â, Ã, etc
I'm doing this:
int charToPrint = 'a';
//use this value to figure which bitmap font to display
The bitmap font does have these characters, but on this line I'm not
getting the values I'm supposed to get, such as: 195 for Ã, 199 for Ç,
etc...
I tried changing my project's character set from Multi Byte to Unicode,
but I don't think that does anything for the char->int conversion...
How can I get this conversion with chars?

Confusion about ActiveRecord associations and foreign keys (Ruby/Rails)
In the below example, do I have to create "employee_id" in the office

class Office < ActiveRecord::Base
belongs_to :employee # foreign key - employee_id
end
Sorry, feels like I'm missing something fundamental. I'm trying to get a

of objects from the one side. Are there any good basic tuts explaining how
this works?
I had to create "_id"s in all the models where I wanted this to work, but
it doesn't seem right from examples I've looked at.
In the below example, do I have to create "employee_id" in the office
model, or is it created automatically by db:migrate?
class Employee < ActiveRecord::Base
has_one :office
end
class Office < ActiveRecord::Base
belongs_to :employee # foreign key - employee_id
end

Generic class type with dictionary in C#
Generic class type with dictionary in C#
I have a dictionary and I would like the key to be able to be different
classes. Right now I'm using:
public Dictionary<dynamic,int> CbList = new Dictionary<dynamic,int>();
This works but I lose the compile-time checking. Is there a better way?
EDIT:
Basically I was wondering if there was a way to have different classes in
a dictionary without losing compile-time checking....
The key classes are related in that they have the same contructors...

check whether all elements of a list are in equal in R
check whether all elements of a list are in equal in R
I have a list of several vectors. I would like to check whether all
vectors in the list are equal. There's identical which only works for
pairwise comparison. So I wrote the following function which looks ugly to
me. Still I did not find a better solution. Here's my RE:
test_true <- list(a=c(1,2,3),b=c(1,2,3),d=c(1,2,3))
test_false <- list(a=c(1,2,3),b=c(1,2,3),d=c(1,32,13))
compareList <- function(li){
stopifnot(length(li) > 1)
l <- length(li)
res <- lapply(li[-1],function(X,x) identical(X,x),x=li[[1]])
res <- all(unlist(res))
res
}
compareList(test_true)
compareList(test_false)
Any suggestions? Are there any native checks for identical for more than
just pairwise comparison?

Understanding overall database design
Understanding overall database design
I have an interest in understanding database design, but I am unsure of
where to start or what I should be paying attention to.
For instance, if I am creating an application, let's use a blog for
simplicity, I know that I will need data. I know that the data I will need
is posts, comments, users, categories, images, etc. I know this "data"
will come in the form of models or tables.
What I have a hard time understanding is when I need a separate table vs.
adding another column in an existing table.
For instance, my Posts table may look like:
ID
Title
Author
Category
Image
Body
However, I want to manage the Categories, so I think I should have another
table just for Categories. What about Images? Should that be a separate
table?
I don't know when to break it out, or keep it together.
Can someone point more to some documentation that would help me learn this
concept? Some guidelines or rules per say.
Thanks!

Difference between these CSS reset methods
Difference between these CSS reset methods
I would like to know if there is any difference between these two methods.
body,ul,li,p,h1,h2,h3,h4,h5{padding:0; margin:0; list-style-type:none;}
and
body,ul,p,h1,h2,h3,h4,h5{padding:0; margin:0;}
li{list-style-type:none;}
without the need to use the global selector * The real issue here is that,
I have mentioned list-style-type:none; in the first example, even though
this attribute applies to the li tag on. But, I find myself something in
need to group all elements and just give them values , even if some values
don't apply to some elements.
So, is there a negative side to that aside from clarity issues?

How can text be so sharp & clear in Xfce4 compared to other desktops and window managers?
How can text be so sharp & clear in Xfce4 compared to other desktops and
window managers?
In the past 1 week i installed different window managers
and desktop environments.
out of these, gnome did not have text as clear and as
sharp as Xfce
but neither did anything else.
text is simply too clear in Xfce4
what is the secret behind this desktop environment ?
is it using special fonts ? or is it using a special setting
to achieve this much precision ?
i want to switch to OpenBox but i am stuck in Xfce due to
clear text , regardless if it is within firefox or outside of
firefox. text is always sharp and clear that it is extremely
easy to read.

Beginner's C++ program for a class
Beginner's C++ program for a class
the assignment is the basic "cin a full name" and then "retrieve First
Middle Last" bit, where you create a program that asks the user to type in
their full first name into a single string and the programs picks apart
the name and outputs it organized seperately. this is what i wrote:
#include <iostream>
#include <string>
using namespace std;
int main()
{
string name;
int index;
index = name.find(' ');
cin >> name;
cout << "First name: " << name.substr(0, index) << endl;
name = name.substr(index+1, name.length()-1);
index = name.find(' ');
cout << "Middle Name: " << name.substr(1, index) << endl;
name = name.substr(index+1, name.length()-1);
cout << "Last name: " << name;
return 0;
}
the code just wont seperate them right, and will not redefine 'name'
correctly. It always just bounces back to the beginning of the string. any
help for a newbie? here's an example output: Teenage Wonder Land First
name: Teenage Middle Name: eenag Last name: Teena Process returned 0 (0x0)
execution time : 7.942 s Press any key to continue.

In the code above if I had the values of

minValue will return as 10 and maxvalue will return as 9. My guess is
because it's treated as a string even though every value is an int. Is
there a way around this?

I would like to know from someone who has already experienced studying
from UK, like How much savings can be made from PhD funding or Research
assistant-ships ? And How does things work there?
I am Masters student in Computer Sciences here in Germany, though I'm
non-European, but still I find German universities to be good enough where
International Students don't need to pay any amount and can get like
1800-2200 Euros a month during PhD positions ! I don't know anything about
UK, can someone guide me through ?

How can I pagination when I use solr facet stats?
I have select all records from solr by solr facet stats, but I can't
pagination them, How can I pagination by the pageSize and pageNum?

How to calculate the frame of a modal view on iPad?
How to calculate the frame of a modal view on iPad?
When a user taps a UITextField, the keyboard will come up. I scroll up the
UITextField to sit just above the keyboard. This is working fine on
iPhone:
- (void) someWhere
{
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(onKeyboardShow:)
name:UIKeyboardWillShowNotification
object:nil];
}
- (void) onKeyboardShow:(NSNotification *)notification
{
CGRect keyboardRect = [[[notification userInfo]
objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue
];
if (keyboardRect.size.height >= IPAD_KEYBOARD_PORTRAIT_HEIGHT) {
self.containerView.y = self.containerView.y -
keyboardRect.size.width;
} else {
self.containerView.y = self.containerView.y -
keyboardRect.size.height;
}
}
However, it is broken on iPad. On iPad, modal view controllers can be
presented as a sheet that takes up only a portion of the screen. You can
see that there is a gap between the last UITextField and the keyboard on
iPad.
UINavigationController* nav = [[UINavigationController alloc]
initWithRootViewController:someRootViewController];
nav.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController:nav animated:YES completion:nil];
I need to detect the offset of the modal view from the bottom of the
screen and add that to the Y coordinate of the UITextField. This will make
the UITextField flush with the top of the keyboard. I attempted to get the
frame of the modal view by doing this:
- (void) viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
// describe is a category function on UIView that prints out the frame
[self.viewController.view.superview.superview.superview.superview
describe];
}
I did indeed get the frame:
x: 114.000000,
y: 192.000000,
w: 540.000000,
h: 620.000000
But as you can see from my code, it is extremely fragile. Since the view
hierarchy of modal view controllers on iPad is not documented, I had to
reverse engineer the hierarchy by slower traversing up the tree to see
which would be the right one. Is there are less fragile way to get the
frame that I actually care about?
