How to fix scrolling issues with liquid layout image 100% width and height?
How to fix scrolling issues with liquid layout image 100% width and height?
I am using a liquid layout on my site. The background is a an image (
slideshow ) and it works how I want. The photo stretches and resizes with
the size of the browser.
However, I just noticed that when I move my browser window as thin or
narrow as it goes, the image is still there but when I scroll to the right
the image cuts off into the background. But full size works fine.
basically I want it to be 100% width and height at all times and never
scroll horizontally or ever exposing the body.
Please let me know what else you need to know to help. Here is the html
and css. thanks

Dispatching GestureEvent (TouchEvent) to View in Viewpager
Dispatching GestureEvent (TouchEvent) to View in Viewpager
I have a ViewPager with a SectionPagerAdapter handling Fragments.
The Fragment has the following Layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="match_parent" >

<ListView
android:id="@+id/transactionlist"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_alignParentBottom="true"

<TextView

</RelativeLayout>
</RelativeLayout>
I'm trying to catch a swipe gesture (left or right) on the TextView
tvMonth but I have absolutely no idea how to dispatch the Event from the
ViewPager down to the TextView itself. The Fragments just keep on
scrolling and thats it.
I can attach an OnTouchListener to the TextView and the recognition works
pretty fine but the tabs are changing anyway.
How can i solve this problem?

MySQL Precison Issues in DECIMAL NUMERIC data type
MySQL Precison Issues in DECIMAL NUMERIC data type
In writing a function for scientific application, I ran into issues. I
traced it back to MySQL's lack of precison.
Here is the page from the official documentation which claims that The
maximum number of digits for DECIMAL is 65 -
http://dev.mysql.com/doc/refman/5.6/en/fixed-point-types.html . It also
describes how the value will be rounded if it exceeds the specified
precison.
Here is reproducible code (a mysql stored function) to test it -
DELIMITER $$
DROP FUNCTION IF EXISTS test$$
CREATE FUNCTION test
(xx DECIMAL(30,25)
)
RETURNS DECIMAL(30,25)
DETERMINISTIC
BEGIN
DECLARE result DECIMAL(30,25);
SET result = 0.339946499848118887e-4;
RETURN(result);
END$$
DELIMITER ;
If you save the code above in a file called test.sql, you can run it by
executing the following in mysql prompt -
source test.sql;
select test(0);
It produces the output -
+-----------------------------+
| test(0) |
+-----------------------------+
| 0.0000339946499848118900000 |
+-----------------------------+
1 row in set (0.00 sec)
As you can see, the number is getting rounded at the 20th digit, and then
five zeroes are being added to it to get to the required/specified
precison. That is cheating.
Am I mistaken, or is the documentation wrong?

Timer not starting in vb.net
Timer not starting in vb.net
net program that uses excel as a datasource. I then fill a datagridview
with this datasource and make changes to the dataset via the datagridview.
I'm trying to find a way to refresh this dataset via a button that will
update the values after a change. My only problem is that I'm trying to
set up a timer in my refresh method but it never initializes/starts. I
can't figure out why, from what I've found online the way to start a timer
in vb.net is to set the timer variable to enabled = true. I've stepped
into my debugger and found that the timer never starts. Here is my code
below, if there is anyone who can figure out why this timer isn't starting
I would greatly appreciate your help!

How to solve these two Queries help please
How to solve these two Queries help please
I am new to SQL and I have a homework assignment. I did all questions
right but still unable to figure out this two queries so please help if
you can. I appreciate you in advance.
I have FOUR tables:
EMPLOYEE which conatin the attributes (Fname, Minit, Lname, Ssn, Bdate,
Address, Sex, Salary, Super_ssn, Dno)
Table DEPARTMENT have the columns ( Dname, Dnumber, Mgr_ssn, Mgr_start_date)
Table PROJECT have the columns ( Pname, Pnumber, Plocation, Dnum)
Table DEPENDENT (Essn, Dependent_name, Sex, Bdate, Relationship)
Q1. For the department that controls the most number of projects, list its
name? I came up with this query but still it just gives me each Department
how many Projects it control but can not get it to work as giving me just
the one that has the most :(
SELECT Dname, COUNT(distinct Pnumber) as NumberOfProjects
FROM Department, Project
WHERE Dnum = Dnumber
GROUP BY Dname;
Q2. Retrieve the names and Ssn of employee who have more dependents than
any other employees?
I came up with this but idk why it does not work. I keep on getting an error
SELECT Fname, Lname, Ssn
FROM Employee
WHERE max((SELECT COUNT(*)
FROM Dependent
WHERE Ssn = Essn));
BTW I am using MySql WorkBench 5.2 and The language is just SQL allowed to
be used

Best practice for appending all Backbone Collection elements to a view?
Best practice for appending all Backbone Collection elements to a view?
For example I have a gallery model that renders a view. That model also
creates a collection of slides. Each slide has it's own view and I would
like to append all these collection views ( the slides ) to the main
gallery view. I can think of a few ways to do this but I'm not sure which
is best. I'm new to backbone so any suggestions are much appreciated.
Thanks in advance!

How do I give all list items a max-width without having all of them fill that width
How do I give all list items a max-width without having all of them fill
that width
http://cdpn.io/gsDHK
Link to Codepen ^
I have a problem with this list. I need to break the words at a certain
point on all of these, but I am unable to change the HTML within the list
items.
I set a max-width of 72px on each list item. But Now they are all 72px
wide. They should be auto width with a max width of 72px. The white space
on either side of each list item has to be even. As you can see on the
Learning Center link, there is more white space than on the others.

ios - View is pixelated when scaled down
ios - View is pixelated when scaled down
I have a UIView that is composed of two UIImageViews. They are concentric
circle shapes. When I scale this view down like this:
CABasicAnimation *resizeAnimation = [CABasicAnimation
animationWithKeyPath:@"transform.scale"];
resizeAnimation.fromValue = [NSNumber numberWithDouble:1.0];
resizeAnimation.toValue = [NSNumber numberWithDouble:0.25];
resizeAnimation.fillMode = kCAFillModeForwards;
resizeAnimation.removedOnCompletion = NO;
The edges of the images get rough and pixelated when scaled down. Is there
anything I can do to prevent this or at least minimize it?

Create HTML elements with php
I have a image heavy wordpress site.
To help with loading I'm using lazy loading.
The lazyload plugin requires the img url in a 'data-original' attribute.
I'm changing the img element using the function to add the image url to
'data-original' and the placeholder to the 'src'
function add_lazyload($content) {
$dom = new DOMDocument();
@$dom->loadHTML($content);
foreach ($dom->getElementsByTagName('img') as $node) {

}
$newHtml = $dom->saveHtml();

Joomla 3.1.4 please help me
Joomla 3.1.4 please help me
I am experimenting with Joomla 3.1.4. Whenever I add a new module the
template does not show at all in the front-end. The site is blank. On
disabling the new module it starts showing properly again. Even a basic
hello world type of module does not seem to work and nor does a third
party extension I have tried. I can see them in the extension manager and
in the module manager and they have installed successfully. Frustrated
with all this I decided to install a new 3.1 template which too installed
successfully. However this template does not show anything in the
front-end either with my module enabled. It almost seems that there is
some sort of security restriction which is disabling the template from
rendering whenever any change is made to the basic installation. Can
someone please give pointers to resolving this odd behaviour.

I serialize a JTree with Xstream but all Nodenames in the xml-file are
lost. The Nodes are custom objects with a toString methode. In my programm
the Tree works fine. I tested the serialization and serialisation with
nodes of the type string, no problems.
How can i serialize a JTree object with custom object nodes to xml?
This is how my tree is build:
JTree tree = new JTree();
tree.setRootVisible(false);
tree.setExpandsSelectedPaths(true);

iOS,getting magnetic field values in milli gauss
iOS,getting magnetic field values in milli gauss
I am using tesla meter sample code by apple to detect magnetic field in my
app,it is giving readings in micro tesla,its values are normally between
25-60 micro tesla,but i want readings in milli gauss,i want to convert
these values in milli gauss using expression 1 microtesla = 10 milli
gauss.but the problem is my values gets very high like 400-800 milli gauss
normally,But the other EMF DETECTORs(K-2 EMF DETECTOR)shows value vary low
in milli gauss i.e 1.5-10 milli gauss.Am i doing anything wrong.any help
would be appreciable.

Contstruct url to router another controller in module
Contstruct url to router another controller in module
I am new to ZF2. I have question for url('route-name', $urlParams,
$urlOptions); ?>
What should I construct $urlParams and $urlOptions when multiple
controller in module?
I rename Album module as Shop and it has two controllers: indexController
and VendorController. In the View>Shop>Vendor>index.phtml, I add:
<p><a href="<?php echo $this->url('shop', array('action'=>'add')); ?>">
Add new vendor</a></p>
aiming this link would links to localhost/shop/vendor/add. But the page
shows the link is: localhost/shop
while what i want is localhost/shop/vendor/add
My understanding is that I should set $urlOPtions field, could anyone give
me example? Thanks all Below is module.config.php:

How can I make this query better?
How can I make this query better?
I'm learning SQL through GALAXQL http://sol.gfxile.net/galaxql.html
Im on lesson 17 - GROUP BY/HAVING
Here is the scenario:
Let's look at couple of SELECT operations we haven't covered yet, namely
GROUP BY and HAVING.
The syntax for these operations looks like this:
SELECT columns FROM table GROUP BY column HAVING expression
The GROUP BY command in a SELECT causes several output rows to be combined
into a single row. This can be very useful if, for example, we wish to
generate new statistical data as a table.
For example, to find out the highest intensities from stars for each
class, we would do:
Select Class, Max(Intensity) As Brightness From Stars Group By Class Order
By Brightness Desc
The HAVING operator works pretty much the same way as WHERE, except that
it is applied after the grouping has been done. Thus, we could calculate
the sum of brightnesses per class, and crop out the classes where the sum
is higher than, say, 150.
SELECT class, SUM(intensity) AS brightness FROM stars GROUP BY class
HAVING brightness < 150 ORDER BY brightness DESC
We could refer to columns that are not selected in the HAVING clause, but
the results might be difficult to understand. You should be able to use
the aggregate functions in the HAVING clause (for example, brightness <
MAX(brightness)*0.5, but this seems to crash the current version of
SQLite.
When combined with joins, GROUP BY becomes rather handy. To find out the
number of planets per star, we can do:
SELECT stars.starid AS starid, COUNT(planets.planetid) AS planet_count
FROM planets, stars WHERE stars.starid=planets.starid GROUP BY
stars.starid
Hilight the star with most orbitals (combined planets and moons). (Note
that the validation query is somewhat heavy, so be patient after pressing
"Ok, I'm done..").
Here was my answer
SELECT stars.starid AS HighStar,
(COUNT(planets.planetid) + COUNT(moons.moonid)) AS OrbitalsTotal
FROM stars
LEFT OUTER JOIN planets
ON stars.starid = planets.starid
LEFT OUTER JOIN moons
ON planets.planetid = moons.planetid
GROUP BY stars.starid
ORDER BY OrbitalsTotal DESC;
This query showed me that the star with the most oribtals has 170 orbitals
So then:
INSERT INTO hilight SELECT result.HighStar
FROM result
INNER JOIN stars
ON result.HighStar = stars.starid
WHERE result.OrbitalsTotal = 170
My question to you is how can I make this query better? I don't want to
have to hard code the 170 orbitals and I dont want to have to create a
second query to insert the data.

struggling in converting the varchar into decimal.
I have tried following CAST( @TempPercent1 AS DECIMAL(28, 16))
Problem is that data also has some values in exponential notation,
example: 1.61022e-016. The sql query is throwing error on encountering
such value. The error is Error converting data type varchar to numeric.
I need to know how to handle exponential notation values during varchar to
decimal conversion?

Update MKMapView when app is in background
Update MKMapView when app is in background
I have code in my iOS app that uses MKMapView to run certain code when the
user moves:
- (void)mapView:(MKMapView *)mapView
didUpdateUserLocation:
(MKUserLocation *)userLocation
{
// The code I want to run
}
I was wondering if it was possible to keep updating even if the app was in
the background, or if not, how to replicate this code in
CLLocationManager.

Better way to re-order Django form errors?
Better way to re-order Django form errors?
Is there a better, more "Django-istic", way to put Django form error
messages in a particular order than the technique shown below? I have a
form with ten fields in it. If the user doesn't fill out a required field
or if they enter invalid data, I iterate through the form's error fields
which I've put in a custom error list by displaying a red "x" and the
error message(s) at the top and a red "x" next to the invalid field(s)
below:
{# template.html #}
<form method="post" action=".">
{% csrf_token %}
{# Non-field errors removed for clarity #}
{# Iterate through error messages in custom ordered error list #}
{% for error_message in ordered_error_list %}
<img src='/static/img/red_x.png' alt='Error'></img>
{{ error_message }}<br>
{% endfor %}
<br>
{% for field in form.visible_fields %}
<div>
{{ field.label_tag }}<br />
{{ field }}
{% if field.errors %}
<img src='/static/img/red_x.png' alt='Error'></img>
{% endif %}
</div>
{% endfor %}
{# Hidden fields removed for clarity #}
<p><input type="submit" value="Continue" /></p>
</form>
Here's my view and helper function:
# views.py
def create_member_profile(request):
if request.method == "POST":
form = CreateMemberProfileForm(request.POST)
if form.is_valid():
# Process form data and redirect to next page...
return HttpResponseRedirect(reverse('review-member-profile'))
# Before I re-POST the form and display the errors, I'll put the
errors in order
else:
ordered_error_list = put_member_profile_errors_in_order(form)
else:
form = CreateMemberProfileForm()
return render_to_response(template, locals(),
context_instance=RequestContext(request))
def put_member_profile_errors_in_order(form):
errors_in_order = [] # List
for error in form['field_1'].errors:
errors_in_order.append(error)
for error in form['field_2'].errors:
errors_in_order.append(error)
for error in form['field_3'].errors:
errors_in_order.append(error)
# ...
for error in form['field_10'].errors:
errors_in_order.append(error)
return errors_in_order
The reason this all seems necessary is that form.errors is a dictionary
and Python dictionaries, by definition, are unordered. However, as I said,
I want any error messages at the top to be displayed in the same order as
the form fields they refer to. I couldn't find any form.errors attributes
that would allow me to re-order the form errors. I don't like the "for
error in form[]" blocks but they seem to be required if I want to strip
the HTML tag from the beginning of each error. Also note that I'm not
checking for errors by putting each "for" loop inside an "if
form['field'].errors" block because omitting this doesn't make a
difference and I want this code to run as fast as possible.
Is there a better way to do this? Thanks!

Choosing authentication method to work with ISA proxy
Choosing authentication method to work with ISA proxy
Given: 1. Client application supports only Basic authentication 2. When
client application runs from machine in the same domain with the ISA -
it's Ok. 3. When client application runs from machine that not belongs to
the ISA server's domain - client cant access to internet.
I know that ISA server can be configured to authenticate only with
integrated authentication method(I cant change this) But why it's work in
case 2 ?
Which method to choose to solve the problem with ISA proxy: 1) add NTLM
method to client or 2) add Kerberos method to client? I hope it will work
with ISA. It is portable. What are cons?

RTMFP and peer-to-peer ports/firewalls
RTMFP and peer-to-peer ports/firewalls
Trying to implement RTMFP for video/audio conferencing app.
The developers have cited this issue:
RTMFP and firewall/NAT traversal options
We have openRTMFP (cumulus) server up and running. We could have this sat
inside or outside the company network (outside for the "cloud" service,
inside for the "local instance" service). But this firewall/NAT issue
looks a show stopper.
Has anybody over come this ?

Changing default line discipline at kernel level/ any way other than( user space) IOCTL TCIOCSETD
Changing default line discipline at kernel level/ any way other than( user
space) IOCTL TCIOCSETD
I am implementing a custom line discipline in order to communicate with
the peripheral connected to the serial port. So during kernel boot itself
i want to assign the custom line discipline to serial port which is
connected to the peripheral. When i walk through the kernel source, i come
to know that by default all the serial port will be assigned n_tty line
discipline with this function tty_ldisc_init(struct tty_struct *tty). Now
how can i identify the particular serial port and assign custom line
discipline? I searched a lot , i am getting all the refernce from user
spcae. I have a dependency, because two component will be using this line
discipline. i component can access from user space while the other is in
kernel space. So if user space component is not up, kernel space module
cannot communicate

Web service registration patterns (proxy with multiple client services)
Web service registration patterns (proxy with multiple client services)
I'm in a bit of an architectural bind. I need to build a high speed cross
web service communication architecture that collocates registrations for
the same user type on a single servicing web service, but at the same time
can scale in the future to handle multiple user types.
Here are the main points:
Just a few users of a single user type
Right now just a few user types … but in the future I expect the number of
user types to grow significantly
All users of the same user type must to be registered on the same web
service (they are going to information share within that single service –
ie use that single service as a hub to share data). Due to the nature of
the data they cannot route it through the proxy after the initial
registration.
As users register they will need to initially connect to a single well
known external point (proxy) which will then farm them out to the correct
service for the day. (ie users won't have any pre-knowledge of what single
service will be servicing them that day … they will have to register with
a proxy first and that proxy will direct them to the correct service for
them)
The 2 possible architectures that I'm debating over:
When the user first contacts the "well known external point" it could
simply respond with "your service is XXX … go contact him directly." Then
the user would be responsible for registering with the service that was
supplied.
When the user first contacts the "well known external point" it could
forward the registration information onto the service and that service
could essentially "reverse register" with the client.
In general architecture 2 feels more complicated, but might have some
merit because we're not depending on the user to "do the right thing".
Thoughts on which approach is better? Alternate thoughts?
See the image for a graphical depiction of the two architectures.
I'd post an image but !stack! wont let me reference it because I don't
have a 10+ reputation!

VB.NET JSON data from website
VB.NET JSON data from website
I'm currently using VB .NET 2010. I'm trying to read data from a JSON
request from the website
https://tradingpost-live.ncplatform.net/ws/search.json (Guild Wars 2
site).
The website requires you to be logged in via the forums. Even having this
in my vb app via a webbrowser object, I am still receiving a 401
Unauthorized error. I assume some sort of cookie is needed???
The biggest issue I have is trying to run the larger search @
https://tradingpost-live.ncplatform.net/ws/search.json?text=&levelmin=0&levelmax=80&count=0
This gives me the error "Unable to download search.json from
tradingpost-live.ncplatform.net. Unable to open this Internet site. The
requested site is either unavailable or cannot be found. Please try again
later.
By using Firefox, I can login and view each of these 2 sites without any
issues. Any chance I can get a pointer in the right direction? So far I've
installed JSON.NET but have no clue how to use it or if I should be doing
something else...... almost midnight and my brain is fried!

LINQ to Entities : "select new" expression tree throws System.NotSupportedException
LINQ to Entities : "select new" expression tree throws
System.NotSupportedException
I'm trying to build an Expression Tree that reflects a "select new" query.
I'm using Ethan's answer to this question. It works great for common lists
but with LINQ to Entities I get this exception:
System.NotSupportedException: Unable to create a constant value of type X.
Only primitive types or enumeration types are supported in this context.
Where X is the Entity I'm querying.
Using the debugger this is the IQueryable with the expression tree:
SELECT [Extent1].[Id] AS [Id], [Extent1].[Nombre] AS [Nombre],
[Extent1].[Apellido] AS [Apellido]FROM [dbo].[Empleadoes] AS
[Extent1].Select(t => new Nombre;String;() {Nombre = t.Nombre})
And this is the IQueryable using normal linq notation (not actually the
same query but to get the point - they are different)
SELECT [Extent1].[Dni] AS [Dni], [Extent1].[Nombre] + N' ' +
[Extent1].[Apellido] AS [C1]FROM [dbo].[Empleadoes] AS [Extent1]
Any help appreciated. Thanks.

Watch Fulham vs Arsenal Live Stream Online Free English Premier League
08/24/2013 How Giroud's debut campaign with Arsenal is viewed depends
completely on expectations. Those who hoped he would completely revitalize
the Gunners' attack were left disappointed, but the French international
put together a solid term.
======>>> http://bit.ly/Ztttjg
======>>> http://bit.ly/Ztttjg
He finished the season with 17 goals across all competitions and also had
double-digit assists. When you consider it was the striker's first foray
into the Premier League, there's no reason to believe he can't take
another step forward in his second season with the club.
Giroud is off to a great start. He scored inside the first 10 minutes of
the opener before Aston Villa turned the match around, and also netted a
penalty against Fenerbahce. The Gunners hope he can maintain that early
momentum against Fulham.

When I use grep to find some texts which I need, it will display lines

For example,
# grep -r ".*Linux" *
path0/output.txt:I hope you enjoyed working on Linux.
path1/output1.txt:Welcome to Linux.
path2/output2.txt:I hope you will have fun with Linux.
then, I want to edit the path2/output2.txt, hence, I type vim

But, I think it doesn't a effective way.

Sizes of arrays declared with pointers
Sizes of arrays declared with pointers
char c[] = "Hello";
char *p = "Hello";
printf("%i", sizeof(c)); \\Prints 6
printf("%i", sizeof(p)); \\Prints 4
My question is, why do these print different results? Doesn't c[] also
declare a pointer that points to the first character of the array (and
therefore should have size 4, since it's a pointer)?

On their pricing page, under full details, every plan has MongoDB and
Redis listed as having 10mb RAM. Does this mean I cannot exceed 10mb worth

that's available in my plan?

Creating variable pagebreaks
Creating variable pagebreaks
Is it possible to procedurally generate page breaks by measuring text/page
space? I am having a problem which you can see here:
There are two problems in this picture. First, the heading should overflow
to the next page because it doesn't fit...but more importantly, and more
annoyingly, the heading should be forced to the next page because its
content does not fit on the same page.
I am procedurally generating my latex from javascript, so it is sort of
hard to post code snippets, but I can show you the function/environment I
am using...it is the second code block in the accepted answer here
Any ideas or tips for measuring the text?

Issue with is_copy_constructible
Issue with is_copy_constructible
Should the type trait be able to handle cases such as std::vector <
std::unique_ptr <int> > and detect that it's not copy constructible?
Here's an example at https://ideone.com/gbcRUa (running g++ 4.8.1)
#include <type_traits>
#include <vector>
#include <iostream>
#include <memory>
int main()
{
// This prints 1, implying that it's copy constructible.
std::cout << std::is_copy_constructible<
std::vector<std::unique_ptr<int> > >::value << std::endl;
return 0;
}
If this is the correct behavior for is_copy_constructible, is there a way
to detect that the copy construction is ill formed? Well, beyond just
having it fail to compile.

How to parse color (saved data) from one controller class to another controller class?
How to parse color (saved data) from one controller class to another
controller class?
I'm practically new in IOS dev.
I would like to ask, let's say if i have a controllerA.m and I have a
@property (nonatomic, weak) UIColor *savedColor;
How can I parse the savedColor from controllerA.m to controllerB.m whereby
i wish to set the background color of an UIImageView *mainImage same as
the savedColor?

Why is the destructor called?
Why is the destructor called?
I wrote a simple vector class which overloads assignment and addition
operators. The code adds two vectors and prints vectors before and after
the addition. Surprisingly destructor ~MyVector() is being called after
the line c=a+b. I do not see the reason why is it so, as neither of
objects a,b and c gets out of scope. Do you understand the reason for
invocation of the destructor?

What are the the most used algorithms for NER? I know the answer sequence
labelling algorithms like HMM, MEMM, CRF, are mostly used but I want
justification why is that???
Why other classification algorithms (SVM , naive bayes etc..) are now
working well and not frequently used in NER task?
Thanks in advance!

intellij plugin com.intellij failed to initialized
intellij plugin com.intellij failed to initialized
everyone, here I encounter a problem after the installation of Intellij
IDEA 12.1.3 on my WINDOWS XP sp2 System.
Here, I just describe it as follows: After the second time installation,
the startup of Intellij encounts that "plugin com.intellij failed to
initialized and will be disabled: Unknown macro:$ROOT_CONFIG$ in storage
spec : $ROOT_CONFIG$/keymaps please restart Intellij IDEA"
PS: this problem only happened for the second and so on installation of
the Intellij IDEA on my system.

Is there a way to change FlowDirection only for a specific Grid RowDefinition in WPF?
Is there a way to change FlowDirection only for a specific Grid
RowDefinition in WPF?
I have an existing UI design and i would like to add RTL support with
minimal changes in existing XAMLs. Currently, most screens are 3x3 Grids
of the following form:
row 0: [ Title - 2 columns ] [ Quit - 1 column ]
row 1: [ Content - 3 column ]
row 2: [ Back - 1 column ] [ empty ] [ Next - 1 ]
I would like to add RTL support only for Row 0 and Row 2. Is that
possible? I couldn't find FlowDirection property for it. I dont mind
overriding the Grid control and implementing this myself i just couldn't
find how... Any ideas?

Storage for Disaster Recovery
Storage for Disaster Recovery
We have a few PostgreSQL servers which add up to 1 TB. We want to do a
PostgreSQL Point-In-Time-Recovery which needs in turn for us to store the
base of each database in a secure location should any disaster hit. I'm
looking at the storage options. I looked at AWS Glacier but the pricing
needs a Math PhD or something. AWS S3 is another option. So I was
wondering if you have used something that can make it even easier. Here
are the requirements I have in mind: 1 - Not so pricey. At 1 TB, AWS S3
will cost less than $100. I guess we could drag the budget to maximum $150
if there's a justification. 2 - We use Linux so something with a Linux
client (lovely if it's available on Debian repos) would be really nice. 3
- We don't really care about deduplication since every time we have a new
version we will basically wipe out the old one. Any hint is appreciated.

How does energy loss work in Redstone Energy Conduits
How does energy loss work in Redstone Energy Conduits
In this situation you see I have my conduits linearly running along the
line of engines. It says on the wiki that the conduits have a 5% energy
loss, implemented at points where energy enters the line. Does this mean
that with 5 entry points linearly spread (like I have here) that by the
time the energy reaches me I've lost 25% of my energy, or still just 5%?

Add .pm file to CakePHP
Add .pm file to CakePHP
I have a .pm file with a 30+ subs. The functionality in those subs needs
to be called from my CakePHP pages. What is the Cake way to include the
.pm file in a CakePHP project so I can call the subs from a View or
Controller?
Where should I put the .pm file? How should I include the file into the
CakePHP project? How do I call the subs in the .pm file?
I can't find anything in the CakePHP documentation. The place that it
seems it should be is in the App, but I can't find anything to do what I
want to do.

Timing - chart is shown too late
Timing - chart is shown too late
My chart is ready now and you can see here an example:
http://www.ariva.de/gold-kurs/push-chart?boerse_id=36
There is one problem left: As we have a lot of advertising on our page,
the chart renders only after all is ready, so sometimes the user has to
wait some seconds. I think, Highcharts waits for document.ready?
Is there a possibility to control the order of the Javascript functions
and show the chart earlier?

How to increase opacity of an image when scrolling?
How to increase opacity of an image when scrolling?
I have a fixed top bar / nav bar on my website and in the center I have a
logo. I want this logo to start off as hidden when a user comes to the
page. As the user scrolls down (around 200 pixels), I want this logo to
fade in. When they scroll back up to the top, I want the logo to fade back
out.
Here is the script I'm using right now:
<script>
$(document).ready(function(){
$(window).scroll(function(){
if($(this).scrollTop() > 100){
$('#logo').fadeIn(1000);
}
});
});
</script>
There are two problems:
1) The nav-bar to the right of the logo is also starting off as invisible
and fading in, though I don't want it to (it doesn't have id=logo). I'm
not sure why this is happening.
2) The logo is not fading out when I scroll back up. I know I need to use
the fadeOut function but when I tried basically reversing the fadeIn
function, I got some funky results.
Here is my site url: http://bestdressedghetto.com/displayPosts.php
And here is a snippet of the relevant topBar code (it is a php file that
is included in all the pages that should have a top-bar....the javascript
code above is in displayPosts.php):
<header>
<center><a href="displayPosts.php" id="logo">
<img class="img-responsive" src="images/bdg-logo-floral.png" />

I am using the mav jetty:run in the command line. I do not know where I am

ActionMailer body string interpolation not printing value of variables, is printing exact string
ActionMailer body string interpolation not printing value of variables, is
printing exact string
I have a mailer that looks like (@user and @foo are passed to the
containing method):
mail(to: @user.email, subject: 'Foo is expired',
body: 'Your Foo reservation for #{@foo.bar.name} in position
#{@foo.position}
has expired. Please recreate the reservation if necessary')
I'm testing it with some puts, puts mail.body looks like:
'Your Foo reservation for #{@foo.bar.name} in position #{@foo.position}
has expired. Please recreate the reservation if necessary'
Am I just mistaken on how I'm doing interpolation? Has it something to do
with ActionMailer, or outputting text to console?
Thanks.

I have tried everything possible to my understand and also calling the

seem to get status bar displayed and it doesn't launch in fullscreen.
I have user the code below in my webpage tag.
<script type="text/javascript">

// close InAppBrowser after 5 seconds
setTimeout(function() {
ref.close();
}, 5000);
}
</script>
Used the

possible with my config.xml and please find code below

I need to get ONLY what between the

I tried :
public string LinkPicCorrect(string path)

string pattern = @"\<img>([^\]]+)\\/>";
string result = Regex.Replace(path, pattern, m =>

// do something with url here
// return the replace value
return @"<img src=""" + url + @""" border=""0"" />";

result = "<img src='" + result + "'/>";
return result;
}
But I've got a parsing error :

dunno though if my code is the right path...

SFML Side Collisions
SFML Side Collisions
I have been playing around with gravity stuff in SFML and I am beginning
to implement collisions to stop upward movement. However I need to be able
to see what side of an object I am hitting so that I can know if it just
restricts left or right movement, upward movement, or downward movement. I
would imagine that there is already a class in SFML that allows you to do
that, but it's not in the SFML 2.1 resource tutorials. Thanks!

Inject Object on deployed REST service
Inject Object on deployed REST service
I'm developing a REST API in an Osgi bundle. I'm using Jersey to deploy
the services into a jetty container with a javax servlet for each class
with REST services.
Each class has an attribute like this
Private DBInterface dbInterface;
With setters and getters, and I need to inject the object from another
bundle once the service is deploy (in runtime). So anyone know a way to do
it?
Thanks in advance.
PD: I'd like to do it without declaring the service as singleton so every
REST request is answered from another instance of the service (actual
stateless REST)

Whats wrong with my Strongly typed DataSet
Whats wrong with my Strongly typed DataSet
I created a dataSet in a solution then added 4 table adapter's to it, all
worked fine. Now after few days I am trying to add another table adapter
and it's not showing it in intellisense. This is how it looks like,
I looked at other xsd in solution and they either don't have "...cs" file
and only have designer.cs file.
for privacy reson cant show code sorry.

Assigning variables from inputs in FOR loop in python
Assigning variables from inputs in FOR loop in python
For my university python course I have an assignment which asks:
Create a change-counting game that gets the user to enter the number of
coins necessary to make exactly two dollars. Design an algorithm, express
it in pseudocode, and then use it to implement a Python program that
prompts the user to enter a number of 5c coins, 10c coins, 20c coins, 50c
coins, $1 coins and $2 coins. If the total value of those coins entered is
equal to two dollars, then the program should congratulate the user for
winning the game. Otherwise the program should display a message advising
that the total was NOT exactly two dollars, and showing how much the value
was above or below two dollars.
I understand how to implement the program but im having trouble trying to
apply a variable to the user inputs without repetition.
I would like to use a FOR loop like so:
def main():
for coin in ['5c','10c','20c','50c','$1','$2']:
int(input("Enter the number of " + coin + " coins you wish use: "))
#Call the main funtion
main()
But how do I assign a new variable to each user input every time it loops?
For my university python course I have an assignment which asks:
Create a change-counting game that gets the user to enter the number of
coins necessary to make exactly two dollars. Design an algorithm, express
it in pseudocode, and then use it to implement a Python program that
prompts the user to enter a number of 5c coins, 10c coins, 20c coins, 50c
coins, $1 coins and $2 coins. If the total value of those coins entered is
equal to two dollars, then the program should congratulate the user for
winning the game. Otherwise the program should display a message advising
that the total was NOT exactly two dollars, and showing how much the value
was above or below two dollars.
I understand how to implement the program but im having trouble trying to
apply a variable to the user inputs without repetition.
I would like to use a FOR loop like so:
def main():
for coin in ['5c','10c','20c','50c','$1','$2']:
int(input("Enter the number of " + coin + " coins you wish use: "))
#Call the main funtion
main()
But how do I assign a new variable to each user input every time it loops?
Stored UIImage pixel data into c array, unable to determine array's element count
Stored UIImage pixel data into c array, unable to determine array's
element count
I initialized the array like so
CGImageRef imageRef = CGImageCreateWithImageInRect(image.CGImage, bounds);
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
NSUInteger width = CGImageGetWidth(imageRef);
NSUInteger height = CGImageGetHeight(imageRef);
unsigned char *rawData = malloc(height * width * 4);
NSUInteger bytesPerPixel = 4;
NSUInteger bytesPerRow = bytesPerPixel * width;
NSUInteger bitsPerComponent = 8;
CGContextRef context = CGBitmapContextCreate(rawData, width, height,
bitsPerComponent, bytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast
| kCGBitmapByteOrder32Big);
However, when I tried checking the count through an NSLog, I always get 4
(4/1, specifically).
int count = sizeof(rawData)/sizeof(rawData[0]);
NSLog(@"%d", count);
Yet when I NSLog the value of individual elements, it returns non zero
values.
ex.
CGFloat f1 = rawData[15];
CGFloat f2 = rawData[n], where n is image width*height*4;
//I wasn't expecting this to work since the last element should be n-1
Finally, I tried
int n = lipBorder.size.width *lipBorder.size.height*4*2; //lipBorder holds
the image's dimensions, I tried multiplying by 2 because there are 2
pixels for every CGPoint in retina
CGFloat f = rawData[n];
This would return different values each time for the same image, (ex.
0.000, 115.000, 38.000).
How do I determine the count / how are the values being stored into the
array?
