Centering items using CSS
Centering items using CSS
I'm having trouble centering things, I've tried table cell and the line
height trick but can't get things to work.
Here's my HTML
<li class="image-item gallery-image-item">
<i class="icon-remove"></i>
<i class="btn-comment icon-comment"></i>
<i class="btn-youtube icon-youtube-play"></i>
</li>
I'm trying to get icon-remove to sit top right in the li.
btn-comment and btn-youtube should be centered in the li, vertically and
horizontally.
The problem I am having is that the icon-remove icon is causing the
centering of the other two items to shift.

Clone closest row from a href
Clone closest row from a href
I have a code that is supposed to duplicate the row that I specify. My
table is made dynamically so I am not able to define an id. I want to be
able to click a button on the specified row and find the closest tr to
duplicate.
The code that is supposed to duplicate is:
function cloneRow()
{
var row = $(this).closest('tr'); // find row to copy
var table = document.getElementById("ScannedItems");
var clone = row.cloneNode(true); // copy children too
clone.id = "newID";
table.appendChild(clone);
}
I am needing to change var row = $(this).closest('tr'); to something else
but I don't know what to change it to so I can get the closest tr from the
a href that is clicked.
Or just duplicate the same row that the a is clicked on.
The a href looks like this
<a onclick='cloneRow();'><span class='glyphicon glyphicon-plus'
style='padding-right:15px;'>

Single thread per request asp.net
Single thread per request asp.net
Is anyone aware of any setting in IIS 7 that will force it to use a single
thread per request, and not allow it to switch threads during a request?
Or go back to a legacy thread model?
Our problem is the entire request, beginning to end uses multiple
connections to different databases and we want to guarantee data integrity
by using TransactionScope (which starts as a light weight transaction,
then is promoted to a distributed transaction, once a second connection is
established).
The reason we need a single thread per request, is when you attempt to
dispose a transaction on a thread different than the thread that started
it, it throws an exception stating it must be disposed on the same thread
that started it. Then the transaction leaks, and nothing gets committed,
and it slowly brings the machine to a grinding halt.

Returning value
Returning value
I have some difficulties with understanding what is really done behind
returning values in C++.
Let's have following code:
class MyClass {
public:
int id;
MyClass(int id) {
this->id = id;
cout << "[" << id << "] MyClass::ctor\n";
}
MyClass(const MyClass& other) {
cout << "[" << id << "] MyClass::ctor&\n";
}
~MyClass() {
cout << "[" << id << "] MyClass::dtor\n";
}
MyClass& operator=(const MyClass& r) {
cout << "[" << id << "] MyClass::operator=\n";
return *this;
}
};
MyClass foo() {
MyClass c(111);
return c;
}
MyClass& bar() {
MyClass c(222);
return c;
}
MyClass* baz() {
MyClass* c = new MyClass(333);
return c;
}
I use gcc 4.7.3.
Case 1
When I call:
MyClass c1 = foo();
cout << c1.id << endl;
The output is:
[111] MyClass::ctor
111
[111] MyClass::dtor
My understanding is that in foo object is created on the stack and then
destroyed upon return statement because it's end of a scope. Returning is
done by object copying (copy constructor) which is later assigned to c1 in
main (assignment operator). If I'm right why there is no output from copy
constructor nor assignment operator? Is this because of RVO?
Case 2
When I call:
MyClass c2 = bar();
cout << c2.id << endl;
The output is:
[222] MyClass::ctor
[222] MyClass::dtor
[4197488] MyClass::ctor&
4197488
[4197488] MyClass::dtor
What is going on here? I create variable then return it and variable is
destroyed because it is end of a scope. Compiler is trying copy that
variable by copy constructor but It is already destroyed and that's why I
have random value? So what is actually in c2 in main?
Case 3
When I call:
MyClass* c3 = baz();
cout << c3->id << endl;
The output is:
[333] MyClass::ctor
333
This is the simplest case? I return a dynamically created pointer which
lies on heap, so memmory is allocated and not automatically freed. This is
the case when destructor isn't called and I have memory leak. Am I right?

Cannot Change TextView Value Inside Fragment From FragmentActivity
Cannot Change TextView Value Inside Fragment From FragmentActivity
I'm developing a simple app based on viewPager. I'm trying to change the
text in a textView inside a fragment from the mainActivity. I tried to
call textV.setText(String) right after the init() method(where the
fragment is instantiated), but the OnCreateView is executed much later, so
the reference to textV is null in that moment. The textV textView is
placed in tab0layout.xml, and become != null when the layout file is
inflated, and it is referenced inside OnCreateView method of Fragment0.
How can I get a valid reference of textV inside my MainActivity? Setting
the text from within the OnCreateView works fine, but I need it available

Order_by in sqlalchemy with outer join
Order_by in sqlalchemy with outer join
I have the following sqlalchemy queries:
score = Scores.query.group_by(Scores.email).order_by(Scores.date).subquery()
students = db.session.query(Students,
score.c.id).filter_by(archive=0).order_by(Students.exam_date).outerjoin(score,
Students.email == score.c.email)
And then I render the things with:
return render_template('students.html', students=students.all())
Now, the issue is that I want the last score for a student to be
displayed, as there are many of them corresponding to each user. But the
first one seems to be returned. I tried some sortings and order_by on the
first query, score, but without success.
How can I affect and pick only one latest result from the "score" to be
paired with the corresponding row in "students"?
Thanks!

The problem is that if I click on a tag to write some other text in it,
the data appear at the end of the array. But I want that the data will be
replaced at the same position in the array. As you can see I also tried to
work with splice(). But I don't know how to push the new data at the
position where the deleted text was living. Have you any idea for that?

first of all I am new in jQuery and my English is not the best.
I try to create a Tagging-System like Stackoverflow and I already found
some useful code. For better understanding here is the current system.
HTML:
<div class="holder">
<span class="test targetLeft" style="background: red;"></span>
<input class="test taggingSystem" type="text" />
<span class="test targetRight"></span>
</div>
jQuery:
$(document).ready(function() {
tags = [];
$(".taggingSystem").keyup(function (e) {
if ($(".taggingSystem").val().substring(0, 1) == " ") {
$('.taggingSystem').val('');
return false;
}
// GET THE VALUE OF THE INPUT FIELD
var value = $('.taggingSystem').val().replace(/\s/g,"");
// IF USER IS HITTING THE BACKSPACE KEY
if (e.which === 8 && value === "") {
var text = $('.targetLeft .tagHolder:last-child
.tagValue').text();
$('.targetLeft .tagHolder:last-child').remove();
$(this).val(text);
}
// IF USER IS HITTING THE SPACE KEY
if (e.which === 32 && value != "") {
$(".targetLeft").append('<span class="test tagHolder"><span
class="test tagValue">' + value + '</span><span class="test
cross">X</span></span>');
tags.push(this.value);
this.value = "";
}
});
$(document).on('click','.targetLeft .tagHolder',function() {
var clickedValue =
$(this).prev('.tagHolder').find('.tagValue').text();
tags.splice(clickedValue, 1);
var value = $('.taggingSystem').val();
if ($(".taggingSystem").val().substring(0, 1) != "") {
$(".targetRight").prepend('<span class="test tagHolder"><span
class="test tagValue">' + value + '</span><span class="test

}
var text = $(this).find('.tagValue').text();
var following = $(this).nextAll();

$('.taggingSystem').val(text);
});

As you can see i've mentioned 3 processes and 3 threads in daemon mode.
Now, when i send 1000's of request after serving some set of requests,
apache should kill the interpreter and reinitiate a new one. Apache tries
to do this, however the killed processes stays back in the memory as
subprocesses of init(PID-1). Thus occupying memory. Eventually number of
processes increases and system crashes due to lack of memory.
So, what can be done to avoid this ? Am i doing anything wrong in

KineticJS layer.get() finds non existent shapes
KineticJS layer.get() finds non existent shapes
I'm experiencing some troubles with KinectJS when I try to get a rectangle
using its id. Take a look at my code here:
var obj = null;
obj = myLayer.get("#asd");
if (obj != null) {
console.log(obj);
}
There are no shapes with #asd - but obj still isn't null. When I log it in
the console i get:
[each: function, toArray: function, on: function, off: function, remove:
function…]
What I want is to check if it found the shape with id #asd. How can I do
that?

Unload a device
Unload a device
I made a device driver. But my system crashed at the moment when it was
deleting the device object. I think the symbolic link was deleted and it
crashed after it was trying to delete the device as I can't see the
symbolic link in the Global. How do I delete this device now. It also
gives me a error popup(system cannot find the file specified
Device\Mydriver) when I try to open the listed Mydriver under devices from
Winobj.
I tried starting the driver's service again. I do get a handle back when
opening the service. But it wont start now. giving the error value of
Cannot find the file specified. I was working fine, i mean starting the
driver before this crash.
I am a beginner with drivers and doing this to learn, please guide.

Setting input value with javascript nullifies PHP post
Setting input value with javascript nullifies PHP post
I have PHP form where I collect a bunch of values from text inputs, but
for one input I have the input filled in via javascript (user selects a
date from a calendar, that date then populates a text input). The way the
form basically works (radically simplified) is this:
<?php
$email = $_POST['email'];
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="text" id="email" name="email" value="<?php echo
$_POST['email']; ?>" />
</form>
And then in jQuery or pure JS I do one of these:
$('#email').val('newValue');
or
document.getElementById('newValue').value = 'newValue';
Both of the above seem to work. They populate the input with the value I
want. But when I submit the form, the PHP variable that's supposed to
collect that value is null. Every other input in the form works, and if I
remove the javascript and manually enter the exact same text that I had
set with JavaScript into the input it works as well.
Any idea what's going on here? I've spent hours puzzling over this to no
avail.

I add here all sample classes i create for showing what i mean. The line
with ((AbstractGenericClass) Activator.CreateInstance(typeof(T))).Host();
crash the program because of InvalidCastException. It must be possible to
call the Host method but i have no idea how i could this, if this dont
operates.
Have you any other idea how this could operate? Or is this totally wrong
what i try?

Replace result from awk
Replace result from awk
Basically, what I want to do is replacing a result parsed from awk with
something else. I have the following awk command :

Which returns :
/var/www/
What I want to do is replace the /var/www/ (of course, it can be anything
and not /var/www/ in particular) in the file. I tried to pipe a sed
command, but I can't figure out how to do it...
Anyone can help ?

It might be problem due to inner join? Actually I want data on the basis
of limit but how I dont know?

Python , vairiable doesnt accumlate over time?
Okay well i'm new to python, and im taking a class in school for this, and
im a bit confused this. We are writing a program/script to calculate
transactions from buying and selling shares. and for some reason i cant
get the "balance" variable to accumulate over time and be subtracted from
and added to from buying and selling the shares. Here's the code, any
input would be amazing ^.^
def main():
#Below is the variables used in the context
balance = float(input("Starting cash amount? "))
numtrades = int(input("Number of trades for today?"))
print('You do not own any shares, but have', balance, 'in cash')
buy = 0
sell = 0
price_per_share = 0
transaction_amount = 0
transaction_amount_buy = 0
transaction_amount_sell = 0
#Below is the prompt for the first transaction, which requires a buy
num_shares = int(input('Number of shares to buy?'))
price_per_share = float(input('Price per share?'))
print(num_shares, "shares for $",price_per_share, "per share cost
$",price_per_share * num_shares)
buy = buy + num_shares
transaction_amount_buy = transaction_amount_buy + (num_shares *
price_per_share)
print("Currently holding", buy, "and have $", balance -
transaction_amount_buy , "in cash")
if balance < transaction_amount :
print('You do not have sufficient funds to purchase', num_shares,

Okay well i'm new to python, and im taking a class in school for this, and
im a bit confused this. We are writing a program/script to calculate
transactions from buying and selling shares. and for some reason i cant
get the "balance" variable to accumulate over time and be subtracted from
and added to from buying and selling the shares. Here's the code, any
input would be amazing ^.^

C++, How do get this function to delete the string stored in the array?
I have a delete function that is supposed to delete a string in an array
by writing over it with the previous strings. The look function see's that
Overide matches and should be deleted. But the code i wrote for the loop
in Delete is not removing that first spot in the array that Overide has
taken up, and the output remains unchanged. Also each phrase after + is
being added into the array so four spots are taken in the array, and sorry
i could not make that part look better the formatting screwed it up.

Can google datastore manage lots of continous write operations?
Can google datastore manage lots of continous write operations?
I'm using google app engine to read data from a google cloud sql database
and write some of its data and some derived data in google datastore, the
database right now doesn't have lots of entries per day, but it's
estimated to have around 200-300 entries per day on the future. I'm
testing to write all the data from the whole databse that now has a number
aproximately equal to these entries in it doesn't work properly, first of
all not all entries are being taken and derived data is sometimes properly
written and other times not, the result changes everytime I do a reading
from the database, so I guess that at least partially google datastore has
something that is related to the problem.
Don't know if google datastore could fall into race conditions or
something like that, although it would be sort of strange, but I'd like to
know if someone has had problems similar to mine and if how he was able to
solve it if he could.
Thanks.

I've a map displayed to the user, and he/she has the ability to plot on
the map his/her location and the google map marker appears, now how do I
fetch programatically the location plotted by the user on the google map.
I will be using this data and storing it in my database, which I can
handle on my own, but I'm unsure of how to fetch the data plotted by the
user.
Someone has already implemented it or has a link or tutorials to it,
please share.

MySQL Order By alternate values
MySQL Order By alternate values
Im having trouble in MySQL query Order By.
First I have a table(tbl_records) that contains 10000+ records. This table
has a primary key called rec_id and a foreign key rec_f_id.
rec_f_id has only two kinds of value (555, 666).
Now my problem is how can I gather the records on the table that orders in
alternate value of rec_f_id.
Eg
SELECT * FROM tbl_records ORDER BY FIELD(rec_f_id, 555, 666) LIMIT 100;
The above query only returns record with rec_f_id = 555. What I want to
have is
| rec_id | rec_f_id |
|1 |555 |
|2 |666 |
|3 |555 |
|4 |666 |
|5 |555 |
|6 |666 |
|7 |555 |

How to perfectly combine Scrum and Kanban
How to perfectly combine Scrum and Kanban
I understand the philosophies of both Scrum and Kanban. I've seen some
articles saying they can be combined together to achieve better efficiency
than using only one of them. Can someone share some experience of running
a scrum team by combining Scrum and Kanban together? Any thoughts are
appreciated.

stop R process without closing console?
stop R process without closing console?
I've accidentally initiated a long process in R without saving what I need
from the workspace I'm using in the R console. I would like to stop the
current process without closing the console. But, what always happens in
an intensive process is that the R Console will not respond. I will then
either have to wait or exit out of the console. I am running 64 bit R
2.15.0 and my OS is Windows & 64-bit. Is there some way to kill R
processes outside the R environment and not close the console?

dot42/xamarin Android programming and applying AlertDialog's
SetOnCancelListener method
I try to 'develop' an Android application with C# (VS2010 + dot42/mono)
which shows lots od messages, gets users' input, and creates AlertDialogs.
The questions are: 1. Do you know how to catch OnCancel Event returned
from Android AlertDialog(s)? 2. How to detect which exactly AlertDialog
sent it?
To be more clear, I am trying to get the AlertDialog.Builder
SetOnCancelListener(IDialogInterface_IOnCancelListener onCancelListener)
to work.
I have created a method which displays a simple message box, and I try to
catch somehow (but it is all wrong so far) the onCancel event. Please see
below. Can you help me?

{
AlertDialog.Builder a_builder = new AlertDialog.Builder(this);
a_builder.SetMessage("Is this all?");
a_builder.SetTitle("Question");

Comparing Multiple Items
Comparing Multiple Items
I apologize for my ignorance, but I've gone through stackoverflow array
element comparison topics, but none of them really have what I need.
I'm programming in java.
My problem is that I need to compare multiple items in an ArrayList,
however I can't seem to figure out how to draw images where the ArrayItem
is.
Like I have an Item in arraylist with an x and y, and in my main activity
class, I try to do
g.getImage(picturename, ArrayItem.x, ArrayItem.y, this);
It asks me to change the items x and y to static.
If someone could point me in the correct way, thanks.

How to get total possible result set from a pagination type query?
How to get total possible result set from a pagination type query?
I'm using SQLLite in AS3 AIR, and am paginating like in the following
example query (100 results per page):
SELECT * FROM table1 WHERE col1 LIKE "%my keywords here%" LIMIT 100 OFFSET 0
It works fine - I change the offset when the user hits a next or previous
button. So the next button's subsequent query is:
SELECT * FROM table1 WHERE col1 LIKE "%my keywords here%" LIMIT 100 OFFSET
100
Just wondering if it's possible to get the total number of possible
results, so I can dsiplay 'page 3 of 12' etc? Or do I have to do two
queries - the first a count(*) without the LIMIT and OFFSET so I get the
result total, and then the above query to get the actual page result?
Thanks for your time and help.

Iterating an array
Iterating an array
I have framed an array like below
iArray = [true, true, false, false, false, false, false, false, true,
true, true, false,
true, false, false, false, false, true]
Condtional check: If anyone of the value in this array is false I will be
showing an error message else if everything is true I will be showing
success message.
var boolIteration = iArray.split(',');
var i;
for (i = 0; i < boolIteration.length; ++i) {
//conditional check
}
I'm struggling to iterate the array using the above condition.
Can anyone point me in the right direction with an efficient solution.

How to prove Restful Web service is a web service?
Yesterday I had an interview and I faced an interesting question where I
got stuck. The Question "How can you say Restful web service is a web
service?". I was trying to explain all the possible ways to prove. But all
the answers were blocked by the question "Servlets can do the same. So
Servlets are restful web service?"
Can anyone share your thoughts?

Angular.js dynamic field generation
Angular.js dynamic field generation
What I'm trying to do is make a number of dynamic radio/checkbox fields
based on data that is passed to me. Unfortunately I don't have control
over the format of this data but it should be ok to get the job done.
This is as far as I have got: http://plnkr.co/edit/LKwueHUzSrC5JpeBY9So
The format of the data I need to end up with in the end is a simple array
like this:
"school_type": [
"Government/State",
"International",
"Co-educational"
]
This data could come from a radio box, or a checkbox if it's selected.
Checkboxes are displayed if there is only one option, radios if more than
one.
So I can get the fields displaying, but the issues I have are:
The name properties on the radio buttons don't seem to work for each set.
I can't work out how to get the value of the checkbox/radio selected...
back to the controller and into the array I need. I thought the easiest
way would be to use the ng-change property available and pass a function
to this but I keep getting errors every way I try.
Any help would be appreciated.

to get in Column D all the corresponding values from column B (1,3,5). If
I input "b", I get 2, 6, so on. Thanks.

Where can I find an authoritative comparison of computer languages?
Where can I find an authoritative comparison of computer languages?
I've reached a point in my career where I want to consider myself less "an
{x} engineer" where {x} is a specific programming language, and I want to
be more of a language-agnostic software engineer.
The obvious next step is to start learning as many languages as possible
to build experience, but there's only so many hours in the day and I'd
rather go about this in a more efficient way. Also, my end goal is not to
be practically proficient in 20 languages, but rather to understand more
deeply the variation among programming languages and what tradeoffs and
design choices they made and why.
I tend to learn better when I can see an overview of the topical landscape
first, before diving into the details. Is there a good, long-form (i.e.,
not a blog post) work on comparative language analysis that does a good
job exploring the variations in programming language features? Or maybe,
alternately, a good coverage text on programming language design?

Adding ' at the start of each row of a table through sql
I have a column called "product-code". These are all populated. I am
wanting to do a query that will insert a ' at the start of each field and
then another query to add a ' at the end of the field.
So for example at the moment a product code might be fmx-2, after the
query I would want it to look like 'fmx-22'
I am looking to do this for all the data sets within the table. I am using
Microsoft Access
Thanks

Csvhelper - read / get a single column of all rows?
Csvhelper - read / get a single column of all rows?
Hi I'm using csvHelper to read in a csv files with a variable number of
columns. The first row always contains a header row. The number of columns
is unknown at first, sometimes there are three columns and sometimes there
are 30+. The number of rows can be large. I can read in the csv file, but
how do I address each column of data. I need to do some basic stats on the
data (e.g. min, max, stddev), then write them out in a non csv format.
Here is my code so far...
try{
using (var fileReader = File.OpenText(inFile))
using (var csvResult = new CsvHelper.CsvReader(fileReader))
{
// read the header line
csvResult.Read();
// read the whole file
dynamic recs = csvResult.GetRecords<dynamic>().ToList();
/* now how do I get a whole column ???
* recs.getColumn ???
* recs.getColumn['hadername'] ???
*/
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original
error: " + ex.Message);
}
Thanks

What are the points I should take care of to choose the struts version

MySQL Trigger for Aging
MySQL Trigger for Aging
I'm trying to create a trigger that will automatically increase the year
column by 1 when the month column is 12, and then empty the month column.
But I don't understand triggers that well and I'm confusing myself in my
attempts, so I was hoping someone could look over this code to see if it
would work or suggest improvements:
CREATE TRIGGER aging BEFORE UPDATE ON dogs
FOR EACH ROW
DELETE FROM dogs WHERE month = 12;
UPDATE year SET year = year+1;
Thanks!

Chrome Zoom issue: absolute Div top position changed while zoom ( Ctrl + )
Chrome Zoom issue: absolute Div top position changed while zoom ( Ctrl + )
I have problem with absolute positioning DIV over the table element. I
have a DIV that's set the position absolute and set the top position to
display the exact place. Now what happened in chrome browser while zooming
(ctrl +) the DIV position has been changed at zoom level 125, 150, 175 ...
etc. But Zoom level 100,200, 300… (Multiple of 100) it's displayed the
same position. The problem was other than the multiple of 100 zoom level
the DIV position changed. How can I fix this issue ?
I have created the sample page in jsfiddle . please run the page in chrome
browser and zoom the browser ( ctrl + ) the red color DIV position will be
change, this is the issue. I really hope some one find a solution for
this.

I have problem with absolute positioning DIV over the table element. I
have a DIV that's set the position absolute and set the top position to
display the exact place. Now what happened in chrome browser while zooming
(ctrl +) the DIV position has been changed at zoom level 125, 150, 175 ...
etc. But Zoom level 100,200, 300… (Multiple of 100) it's displayed the
same position. The problem was other than the multiple of 100 zoom level
the DIV position changed. How can I fix this issue ?
I have created the sample page in jsfiddle . please run the page in chrome
browser and zoom the browser ( ctrl + ) the red color DIV position will be
change, this is the issue. I really hope some one find a solution for
this.
