performing normal. But when i use fileTransfer.onprogress then it seem
download more size of file( my file 20Mb and it download 40Mb more than
2x).
fileTransfer.onprogress = function(progressEvent) {
if (progressEvent.lengthComputable) {
var percent = progressEvent.loaded/progressEvent.total;
//percent allways equal 2, than more 2x size of real file
console.log(percent);
}
};
Else FileTransfer() upload working well.
I don't known why? Can anyone help and explain for me. Thank you so much.

Bootstrap 3 - Invisible Dropdown on IE9 Bug. Fix?
Bootstrap 3 - Invisible Dropdown on IE9 Bug. Fix?
Someone pointed out a bug on the site package I've created using Bootstrap
3. ( http://getbootstrap.com/ )
Notice on my website (using Internet Explorer 9) that the dropdown menus
show shadows, but no content. ie, they are boxes holding invisible
content. (http://www.clipartillustration.com/)
I've searched and found some similar issues but they don't seem to fix the
one I'm stating.

I know this should remove any characters from string and keep only numbers

but I wish to remove any special characters and keep any letter of any

mmenu and sticky nav in android
mmenu and sticky nav in android
I'm using a mmenu with a sticky header and have utilized 2 fly-out menus
each with an absolutely positioned icon on each side of the header. It
seems to work perfectly in IOS but on my old-school android, it doesn't.
When the header isn't sticky it works perfectly in Android however.
But when the header is sticky the div isn't moving like the rest of the
content to the right or left to make room for the menu fly-out.
Anyone else experience this issue? Any thoughts?

Querying on Date in Mongo
Querying on Date in Mongo
I'm inserting a Mongo doc with the following time-stamp:
val format = new java.text.SimpleDateFormat("yyyyMMddHHmmss")
format.format(new Date()).toLong
Here's what the sectiolooks like from Mongo's shell:
"{Timestamp" : NumberLong("20130919161948")}"
Based on a few tests, it appears to me that I can simply compare 2
documents by Timestamp by simply checking > or < for the yyyyMMddHHmmss
format.
Please let me know if this time-stamp is OK for Mongo. Will I be able to
query with it?

getting id in context menu
getting id in context menu
I have seen multiple posts regarding this but after all those solutions I
stiil have this weird issue. I have implemented the following
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item
.getMenuInfo();
int index = info.position;
Log.i(TAG,"onContextItemSelected id:"+String.valueOf(index));
}
I still get id as 0,1,2,.. and not the actual database row id. I am
implementing list item click listener as well and here I get the correct
row id based on the row. Is there something that I am missing.

(mod) Rewriting Out of Order Parameters
(mod) Rewriting Out of Order Parameters
Is it possible to re-write parameters that are not always in the same
order in a URL?
For example, we might have a url like
/products/type/animal/id/123456
But it could also appear as:
/products/id/ab123456/type/animal
Using a mod rewrite statement like
/products[.html?]?(?:/id/([^/])?)/?(?:/type/([^/])?)/?
"products.html?id=$1&type=$2" [L, NC]
works fine for the the first example but of course fails for the second.
Is there anyway around this?

No space between buttons 'on next the line'
No space between buttons 'on next the line'
I trying to create buttons with round corner to simulate menus tabs. If

My issue is that there is no spacing between the buttons on the first line
and those on the following lines:
I am trying to replicate this issue in JSFiddle, but it does not happen
there:
My HTML is:

<span class="menuButton">Button I Button I Button I</span>
<span class="menuButton">Button II Button II Button II</span>

Create output file in matlab containing numeric and string cells
Create output file in matlab containing numeric and string cells
I am currently working on a project where I have to program the same tool
both in Matlab and R and compare both software options. I started in R and
now I am translating the code to Matlab but I am now stuck at the most
important part. The output file that the tool creates after doing the
analysis. Basically, my tool makes an analysis that loops n times, and
after each loop I get many variables that go into an output table. So, to
be more clear, after each loop I get variables:
A = 123
B = 456
C = 'string1'
D = 'string2'
E = 789
The values in each variable change after each loop, I just want to make
clear that the variables are both numeric and string values since this is
what causes my problem.
In R what I do after each loop is:
outp <- cbind(A,B,C,D,E)
and create a data frame containing each variable in one cell arranged
horizontally to afterwards add the result of each loop vertically in a new
data frame:
outp2 <- rbind(outp2,outp)
so in the end I get a data frame (outp2) with A,B,C,D,E columns and n rows
containing the values of each variable after each loop. So at the end of
the looping process I can use write.csv function and create an output file
of outp2 that contains both numeric and string columns.
I tried to do this in Matlab but I cannot find a function that can join
the data in the same way I am doing it in R because using brackets '[]'
only allows me to join numeric kind of variables. So basically my question
is: How can I replicate what I am doing in R in Matlab?
I hope I was clear enough, I found it a bit hard to explain.

sql removing multiple records with mutltiple date values
I have the following sample data that I need to clean the records by
specific date. For this example, lets use anything older than march 2012
will need to be removed along with other related records.
Author Book date
-------------------------------------
Smith Bk1 01/01/2012
Smith Bk2 02/01/2012
Smith Bk3 02/25/2012
Johnson Bk1 06/01/2011

Jones BK2 01/01/2002
Jones BK3 01/01/2009
Jones BK4 08/01/2013
Above is the data set. So if the Author has a book in the table that is
older than 03/01/2013, then All of the records need to be removed. If they
have at least one Book newer than the date specified then All records are
kept. In this scenario, the Jones records are the only ones to be kept in
the table data set.
Thanks for any help, I appreciate it.

Why is cornerRadii parameter of CGSize type in -[UIBezierPath bezierPathWithRoundedRect:byRoundingCorners:cornerRadii:]?
Why is cornerRadii parameter of CGSize type in -[UIBezierPath
bezierPathWithRoundedRect:byRoundingCorners:cornerRadii:]?
I can't figure this out... I'm playing with
-[UIBezierPath bezierPathWithRoundedRect:byRoundingCorners:cornerRadii:]
as such:
bezierPath = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(10, 10,
80, 80)
byRoundingCorners:(UIRectCornerBottomLeft)
cornerRadii:CGSizeMake(20, 20)];
And it works as expected. But if I replace cornerRadii:CGSizeMake(20, 20)
with, say, cornerRadii:CGSizeMake(20, 5) or CGSizeMake(20, 40), there's no
difference.
Why is cornerRadii CGSize and not CGFloat then? What is CGSize.height for?
Any ideas and advice will be greatly appreciated :)

-[UIBezierPath bezierPathWithRoundedRect:byRoundingCorners:cornerRadii:]
as such:
bezierPath = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(10, 10,
80, 80)
byRoundingCorners:(UIRectCornerBottomLeft)
cornerRadii:CGSizeMake(20, 20)];
And it works as expected. But if I replace cornerRadii:CGSizeMake(20, 20)
with, say, cornerRadii:CGSizeMake(20, 5) or CGSizeMake(20, 40), there's no
difference.
Why is cornerRadii CGSize and not CGFloat then? What is CGSize.height for?
Any ideas and advice will be greatly appreciated :)

Get the current store -Ext JS
Get the current store -Ext JS
Simple question here,
I have a grid in my application that can hold one of any 3 given stores
(utlizes bindStore() function).
Is there a function to retrieve the current store? Something like:
Ext.getStore(grid.currentStore());
Cheers!

Composite C1 console edit button available for non translated data
Composite C1 console edit button available for non translated data
We are using Composite C1 version 2.1.1 with static C# data. This data is
localizable (ILocalizedControlled) and is shown on top of the data tree
(TreeDefinitions\GlobalData.xml). Users are able to translate the data to
their selected language, but somehow it is possible to "Edit" the data
before translating it. This means that when they do it wrong (i.e. in
stead of first choosing "Translate Data" and then "Edit", choose "Edit"
directly) translated data will appear on the source language site. Which
is very annoying because the source data is lost as well. Seems that when
choosing a data item only "Translate Data" should be possible, but now
four buttons are shown (Translate Data, Edit, Add and Delete). So I would
like to be able to change this behavior, but can't seem to find where or
how to influence this.
Hope anyone can help.

How to query a restful webservice using Python
How to query a restful webservice using Python
Writing a Python script that uses Requests lib to fire off a request to a

As you can see, there is this weird variable 'response_length' that i need
to pass to the response object (optional argument) to be able to read the
content. This variable has to be set to a numeric value that is equal to
length of the 'content'. This obviously means that i need to know the
response-content-length before hand, which is unreasonable.
If i don't pass that variable or set it to a value greater than the
content length, I get the following error:

How to create an error message box for an empty text box: VB 2010 Express
How to create an error message box for an empty text box: VB 2010 Express
I am taking VB this semester, and while it is not required for this
particular assignment, I am curious how I can create a MessageBox error if
a text box is left empty.
We just covered using the Try/Catch statement, and I have successfully
created MessageBoxes for text boxes whose text is only numeric. For
example, a user must enter a name, and two numeric amounts. I am trying to
create an error if the Name text box is left empty, stop the program from
calculating the two amounts and return the insertion point to the Name
text box.
Is there an easier way to do this? The If/Then statement I currently have
does not stop the program from calculating (I am just starting out so go
easy on me):
Private Sub CalculateButton_Click(sender As System.Object, e As
System.EventArgs) Handles CalculateButton.Click
'Declare Variables
Dim SellingPrice, CostValue, Commission As Decimal
'Test to see if a name was provided the NameTextBox
If NameTextBox.Text = "" Then
MessageBox.Show("Please enter a Salesperson's name", "No entry",
MessageBoxButtons.OK, MessageBoxIcon.Error)
With NameTextBox
.Focus()
.SelectAll()
End With
End If
'Test if Numerical data was entered for SellingPriceTextBox
Try
'Convert Selling Price
SellingPrice = Decimal.Parse(SellingPriceTextBox.Text)
'Test if Numerical data was entered for CostValueTextBox
Try
'Convert Cost Value
CostValue = Decimal.Parse(CostValueTextBox.Text)
'Calculate the Commission earned
Commission = Decimal.Round(COMMISSION_RATE * (SellingPrice
- CostValue), 2)
'Format and display results
TotalCommissionLabel.Text = Commission.ToString("C")
Catch CostValueException As FormatException
'Handle a Cost Value exception
MessageBox.Show("Value must be a numeric value.", "Invalid
Input",
MessageBoxButtons.OK, MessageBoxIcon.Exclamation)

Are there any way to skip the next activity using JS
Are there any way to skip the next activity using JS
For example, I have an action like this:
Run external JS => Save file => Run External Bat
The problem is , are there any way in the JS to skip the save file acvitiy ?
What I would like to do in the JS is :
if (some condition) { //Skip the save file activity }
Is it possible or any workaround can achieve the same result? Thanks

} else if (testScore >= 0){

}

studentGrade.inputScore(); //get score from user and assign it to the

studentGrade.assignLetter(); //assign a letter grade based on the

studentGrade.printResult(); //display the letter grade
}
}
}
Neither will compile. I can't seem to figure out why. Also I am used to
using the relational operator "::" in c++ which references the driver code
to the classes in the other code. I was wondering how to do that in java.

I'm looking for a while to make it works.
This is my last try.
I have this html :
<td>
<input type="text" value="" class="typeahead" style="width: 310px"
autocomplete="off" data-provide="typeahead" />
<input type="hidden" value="" class="delivery" name="delivery[]" />
</td>
And on JS side, I have this :
$(".typeahead").on("create", function() {
$(this).typeahead({
limit : 20,
remote : {
url: '/ajax/places/?query=',
replace: function(url, encodedUrl) {
return url + encodedUrl + '&categorySon=5';
},
filter: function (result) {
var list = [];
result.aaData.map(function (item) {
list.push({
value: item.name + ' (' + item.code + ')',
id: item.id
});
});
return list;
}
}
}).bind('typeahead:selected', function (obj, datum) {
$(this).parent().parent().find("input[type='hidden']").val(datum.id);
});
});
So, when I add dynamycly an other input typeahead it doesn't works (even
on the one create on loading of the page, it works fine with basic
$(".typeahead).typeahead...)
thanks a lot for your help !

Optimizing the load of numerous images
Optimizing the load of numerous images
I have a website that displays about 30 fairly small color gif files on
the main page. When looking into optimizing the site, I ran Google's
PageSpeed Analyzer. It suggests that I create a CSS sprite for them. The
problem that I'm running into is that the main page does not show the same
30 images per user and/or per page load. Also, the images are replaced
about once a month.
I was thinking maybe a dynamic generation of a CSS sprite or a CSS sprite
that contains all possible images. I am looking for the most efficient way
of accomplishing this.So my question is, What can I do to reduce the
requests or optimize this aspect while allowing for the change described?

How to read the input and replace the character as required?
How to read the input and replace the character as required?
The code below shows a part of my program. I am trying to create an atbash
encryption for a small challenge (atbash is an encryption method; example,
I type in 'hello' and the program will output 'svool'. It reverses the
letter order. More here: http://en.wikipedia.org/wiki/Atbash)
The program works...sort-of, when i type 'abcdef' the program outputs
'zyxwvu'. However, say i wanted to type an actual word. The program won't
cycle through the array and will just output "test" (which it's NOT
supposed to do). How do I fix this?
char letter1 [] = new char []
{'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'};
char letter2 [] = new char []
{'z','y','x','w','v','u','t','s','r','q','p','o','n','m','l','k','j','i','h','g','f','e','d','c','b','a'};
for (int i = 0 ; i < input.length() ; i++)
{
if(i == input.length()) {
break;
}
if (input.charAt(i) == letter1[i]) {
input.setCharAt(i, letter2[i]);
System.out.println (input);
}
else if (input.charAt(i) != letter1[i]){
System.out.println ("test");
}

Onsite image cropping functionality with a fixed ratio with RoR, Paperclip, S3 setup
Onsite image cropping functionality with a fixed ratio with RoR,
Paperclip, S3 setup
I am looking for a way to provide a onsite image cropping functionality to
the user. However, I would only like to allow them to crop their image
with a given respect ratio. The idea is similar to the square protrait
cropper for some social website when you upload an avatar. Can anyone
suggest a solution for this? Thank you.

Multiple ObjectStateManager errors when attempting to update an Entity in Entity Framework
Multiple ObjectStateManager errors when attempting to update an Entity in
Entity Framework
This is a problem that has been cropping up for months and is proving to
be extremely frustrating.
I have an entity ... StorageContract ... which inherits from Contract;
created from a TPT (Table per Type) relationship (I am not sure if that
makes a difference). When I attempt to update an existing StorageContract
by passing an updated definition of the contract to the Update method ...
public StorageContract UpdateStorageContract(StorageContract contract)
{
Context.ObjectContext.ApplyCurrentValues("Contracts", contract);
Context.SaveChanges();
return contract;
}
... I get the error ...
"An object with a key that matches the key of the supplied object could
not be found in the ObjectStateManager"
I found the following post ... "An object with a key that matches the key
of the supplied object could not be found in the ObjectStateManager" ...
which led me to try "attaching" the contract parameter.
public StorageContract UpdateStorageContract(StorageContract contract)
{
Context.ObjectContext.AttachTo("Contracts", contract);
Context.SaveChanges();
return contract;
}
... Which results in an error that seems to be confusingly quite the
opposite of the previous error ...
"An object with the same key already exists in the ObjectStateManager. The
ObjectStateManager cannot track multiple objects with the same key"
The first error indicated that the entity could not be updated because it
could NOT be found ... where as this one seems to suggest that it cannot
be updated because it already exists(??). Anyway that led me to the
following post ... "An object with the same key already exists in the
ObjectStateManager. The ObjectStateManager cannot track multiple objects
with the same key". SO I reworked the code again based on that ...
public StorageContract UpdateStorageContract(StorageContract contract)
{
var origEntry = Context.Entry<StorageContract>(contract);
if (origEntry.State == System.Data.EntityState.Detached)
{
var set = Context.Set<StorageContract>();
StorageContract attachedEntity = set.Find(contract.Id);
if (attachedEntity != null)
{
var attachedEntry = Context.Entry(attachedEntity);
attachedEntry.CurrentValues.SetValues(contract);
}
else
{
origEntry.State = System.Data.EntityState.Modified;
}
}
Context.SaveChanges();
return contract;
}
Which results in the same error ...
"An object with the same key already exists in the ObjectStateManager. The
ObjectStateManager cannot track multiple objects with the same key"
I am chasing this down a rabbit hole that caves in at every turn! I am
desperate for help with this!!
Thanks!

Nested for loop Java text output
Nested for loop Java text output
I have been trying to write a method called printDesigns that uses nested
for loops to output this:
-----1-----
----333----
---55555---
--7777777--
-999999999-
The dashes decrease by one on each side, I know its hard to see.

Function arguments passed by value
Function arguments passed by value
I'm reading that in JavaScript, a common point of confusion arises because
variables of primitives are passed by value, and variables of objects are
passed by reference, while in function arguments, both primitives and
references are passed by value.
In the course of my tinkering, I've made up the following code, but am
having trouble wrapping my head around it.
> function setName2(obj) {
... obj.name="matt";
... obj = new Object();
... obj.name="obama";
... }
If I set
var person = new Object();
person.name = "michelle";
Then run
> setName2(person);
I get
> person.name;
'matt'
Which makes sense because the new object created is a pointer to a local
object, hence not affecting the property of the global 'person'.
However, what if I first set
var obj = new Object();
obj.name = "michelle";
Then run
> setName2(obj);
?
I get the same outcome. Does this mean that the compiler recognizes the
two variables of the same name (obj global and obj local) as references to
different locations within the heap, each having some different pointer
association, or is there a different explanation for this phenomenon?

Prevent title from appearing on mouseover
Prevent title from appearing on mouseover
I couldn't find anything that solved my problem in previous posts, so
here's my question:
I'm working with fancybox image gallery and when I mouse-over the
thumbnails on the main page, they're picking up the title from the first
big image in each of the the sets that pop up in the lightbox. I don't
want that to happen, I don't want anything appearing on mouse-over of the
thumbnails.
Is there anyway to keep that from happening?
Thanks,
Kirk

Advantages of a VM
Advantages of a VM
The majority of languages I have come across utilise a VM, or virtual
machine. Languages such as Java (the JVM), Python, Ruby, PHP (the HHVM),
etc.
Then there are languages such as C, C++, Haskell, etc. which compile
directly to native.
My question is, what is the advantage of using a VM (outside of
OS-independence)? Isn't using a VM just creating an extra interpretation
step, by going [source code -> bytecode -> native] instead of just [source
code -> native]?
Why use a VM when you can compile directly?
EDIT
My understanding is that Python, Ruby, et al. use something akin to a VM,
if not exactly fitting under such a definition, where scripts are compiled
to an intermediate representation (for Python, e.g. .pyc files).
EDIT 2
Yep. Looked it up. Python, Ruby and PHP all use intermediate
representations, but are simply not stored in seperate files but executed
by the VM directly. See question : Java "Virtual Machine" vs. Python
"Interpreter" parlance?
" Even though Python uses a virtual machine under the covers, from a
user's perspective, one can ignore this detail most of the time. "

Swing clients, Java Server
Swing clients, Java Server
My goal ist to develop an application which is used to set up a
videoconference between two seminar rooms. I have a MySQL database
containing the room and user informations and a java server polling the
room states (=connection state of videoconference). With a desktop
application, a user should be able to log himself in (user info in db) and
start a connection between two videoconference systems by selecting the
rooms he wants to connect (room info, vid-conf info ind db).
I figure I need the following parts in order to this
A service which polls the videoconference systems
A database service providing room and user informations
A desktop client application
I played around to test how I can do this and programmed a Java server
which polls the videoconference systems and stores this info. A swing
client can open a socket to the server and ask for a room state. Reading
db information is also programmed in the client with hibernate. Now this
works but it is far from a good style and I'd like to redesign the whole
thing.
So let's say, I begin from scratch. I really am having difficulties on how
to start to come to a clean programmed result. I know the following
questions are not very specific but I hope one of you can give me
directions on how to proceed or which technology/framework to use.
First a few requirements:
The server runs on a windows machine. It currently is installed as windows
service (and does only provide the room states).
The clients have to be desktop applications, less than 20 clients are
expected to run simultaneously.
The clients are used in a university network where also the server and the
videoconference systems reside.
And a few questions:
How do I design the server? I am sure I do not have to reinvent the
wheel... The server should be capable of providing database objects and
store/provide the current state of each room.
Would you store the current room state in the database? I also need to
keep track of current connections (which room is connected to which).
Currently I store the basic room info (room name, videoconference ip and
such) in the database, the room state (ready/ occupied, sending/receiving)
is handled seperately by the server.
How to access said server with a (Swing-)Client? Currently I use hibernate
to acces the db (yes I know, not a good idea with multiple clients for the
same db) and sockets with a clear text protocoll to access the room
states.
How can I implement a chain of actions like this one: The user selects two
rooms to connect. The clients sends this request to the server. The server
sends the request to the videoconference systems, both videoconference
systems start, when started they provide a feedback, the feedback should
be made available to all clients so everyone is informed that a conference
is in progress.
I do of course not expect detailed solutions to my problem but every hint,
link, etc. in the right direction will be appreciated. Thanks.

Would you store the current room state in the database? I also need to
keep track of current connections (which room is connected to which).
Currently I store the basic room info (room name, videoconference ip and
such) in the database, the room state (ready/ occupied, sending/receiving)
is handled seperately by the server.
How to access said server with a (Swing-)Client? Currently I use hibernate
to acces the db (yes I know, not a good idea with multiple clients for the
same db) and sockets with a clear text protocoll to access the room
states.
How can I implement a chain of actions like this one: The user selects two
rooms to connect. The clients sends this request to the server. The server
sends the request to the videoconference systems, both videoconference
systems start, when started they provide a feedback, the feedback should
be made available to all clients so everyone is informed that a conference
is in progress.
I do of course not expect detailed solutions to my problem but every hint,
link, etc. in the right direction will be appreciated. Thanks.

Generic class and new() with interfaces
Generic class and new() with interfaces
Is there a way to use a generic class passing an interface as T and still
have the new() constraint?
Class Thing<T> where T : new()
new Thing<ISomething>()
I did not want Thing to be constrained by ISomething but I guess the idea
is just to keep adding interfaces to Thing?
Thanks

Non-exact Vlookup with multiple search criteria - Microsoft Excel
Non-exact Vlookup with multiple search criteria - Microsoft Excel
I'm having a problem extracting some date from a table in Excel. The data
is in the format shown in the diagram below:
Name---------------------------First Name------------------- Surname
Billy Peter Hunt---------------Tim---------------------------Smith
Chris Paul Smith---------------Brad--------------------------Johnson
Dave Colin Jones---------------Karen-------------------------Perry
Dr James Clyde Watt------------Dave--------------------------Jones
John Phil Cross----------------Chris-------------------------Smith
Kelly Holmes-------------------Hector------------------------Baxter
Norman Bryce-West--------------Billy-------------------------Hunt
For each person listed in the First Name and Surname columns (e.g. "Tim
Smith", "Brad Johnson" etc) I want to be able to search through the Name
column, for the first cell that contains both the First Name AND Surname
of the person being searched for, and output the results into a new
column.
As there are lots of middle names, titles and double-barreled surnames in
the Name column, I can't use an exact match search. I need to search the
contents of each cell to see if they have any matching sub-strings.
I've found that I can use Vlookup with wildcards to search based on either
the First Name OR Surname columns, but I can't figure out how to use both
columns simultaneously as search criteria.
Any help with this would be much appreciated. I've been typing all sorts
into Google and making lots of frustrated grunts to no avail.

TListBox sync with TStringList
TListBox sync with TStringList
I've got a background thread sending messages to the main thread which, in
turn, adds the messages to a TListBox like a log.
Thing is, this background thread is really fast and I dont really need to
update the log that fast. I'd like to add the messages to a TStringList
and set a timer to update the TListBox every second or so.
I've tried using:
listBox1.Items := StringList1;
or
listBox1.Items.Assign(StringList1);
in the OnTimer event and it works. Thing is, it never let's the user
really scroll or click the listbox, because it refreshes every second.
I'm using Delphi XE4
Is there a more elegant way to sync the contents of the listbox with this
background StringList (or any other list if necessary)? Thank you in
advance!

Positive integer from Python hash() function
Positive integer from Python hash() function
I want to use the Python hash() function to get integer hashes from
objects. But built-in hash() can give negative values, and I want only
positive. And I want it to work sensibly on both 32-bit and 64-bit
platforms.
I.e. on 32-bit Python, hash() can return an integer in the range -2**31 to
2**31 - 1. On 64-bit systems, hash() can return an integer in the range
-2**63 to 2**63 - 1.
But I want a hash in the range 0 to 2**32-1 on 32-bit systems, and 0 to
2**64-1 on 64-bit systems.
What is the best way to convert the hash value to its equivalent positive
value within the range of the 32- or 64-bit target platform?
(Context: I'm trying to make a new random.Random style class. According to
the random.Random.seed() docs, the seed "optional argument x can be any
hashable object." So I'd like to duplicate that functionality, except that
my seed algorithm can't handle negative integer values, only positive.)

in Oracle, how can i read a large blob as a text document
in Oracle, how can i read a large blob as a text document
I have a BLOB which actually contains text from a few hundreds chars to
20K+ chars. I am given this (I know it should be a CLOB, but not my
choice). I need to be able to get the entire text document. The closest
I've come is this:
select utl_raw.cast_to_varchar2(dbms_lob.substr(blob_data,2000,1)) from
my_table where id = 'id_value'; --get up to 2000
I can't get past 2000 at a time, though I guess I can get the size (using
dbms_lob.getlength) and get 2000 at a time and put it together. Seems like
there should be a better answer. Does anyone have a better way?

Is there really a resource leak if I close the inner stream?
Is there really a resource leak if I close the inner stream?
I ran a dynamic code analysis tool on one of our programs and this pattern
was identified as a resource leak:
...
FileInputStream fileInputStream = new FileInputStream(file);
try {
data = someMethod(new BufferedInputStream(fileInputStream));
// Assume that someMethod(InputStream) internally reads the stream
// until BufferedInputStream.read() returns -1.
...
}
finally {
...
try {
fileInputStream.close();
} catch (IOException e) {
...
}
}
Specifically, the analysis tool marked the new BufferedInputStream(...)
call as a resource leak because it is never closed. In this pattern,
however, the underlying stream fileInputStream is closed and the
BufferedInputStream goes out of scope.
Given this situation, is this actually a resource leak?

Why the standard explicate allow C-style cast to convert derived object to inaccessible base sub-object?
Why the standard explicate allow C-style cast to convert derived object to
inaccessible base sub-object?
I just get the information from this cool blog that we can cast the
derived object to inaccessible base class sub-object. On the other hand,
the static_cast cannot be used to do that.
class Base {};
class Derived: private Base {};
void main()
{
Derived d;
Base* b = (Base*)&d; // compile passed.
Base* b = static_cast<B*>(&d); // compile error.
}
Cast the object to private base sub-object will break the private keyword
mean, it make the private object accessible to caller. I assume there is
some reason why C++ standard explicit allow this, and the reason
"compliant to C language" doesn't work to me because there doesn't have
inheriate in C language even you can simulate it, which is unrelated to
this problem.
Can anyone share some thought on this?

c++ : dynamic number of nested for loops (without recursion)
c++ : dynamic number of nested for loops (without recursion)
I'm writing a code segment that iterates through every permutation of n
digits. So for example, if n = 3, I would want to iterate through each of
the following elements:
0, 0, 0
0, 0, 0
...
0, 1, 0
...
1, 0, 0
...
2, 3, 4
...
9, 9, 9
You get the idea. This is very easy to code using nested for loops:
for(digit1 0 to 9)
for(digit2 0 to 9)
for(digit3 0 to 9)
But I want to generalize this to n digits. If for example n = 10 I now
need 10 nested for loops.
I've thought about this and realized that the problem can be solved using
recursion (depth first search through a tree, with each node having 10
children, 0 to 10, and stopping at depth n). But I'm aiming for high
performance so I don't want to use recursion due to the overhead. What
other alternatives do I have?

Fail to inherit from QMainWindow
Fail to inherit from QMainWindow
I currently have a UI form which contains many layouts(Horizontal and
Vertical) and then the form itself has a horizontal layout the form is
currently inheriting from QDialog. Now when I try to replace QDialog with
QMainWindow. So that I could add a toolbar to it. It seems that the
QTDesigner does not like my change and when I open the form up in
QTDEsigner it says that the form still inherits from QWidget. Any
suggestion on what I might be doing wrong ? Could this be because of the
presence of multiple layouts already present on the form

{
public List<Card> cards;
public Deck(string[] values, string[] suits)
{...}
...
}
and a derived class EuchreDeck:
public class EuchreDeck : Deck
{
string[] values = new string[] { "9", "10", "J", "Q", "K", "A" };
string[] suits = new string[] { "clubs", "spades", "hearts", "diamonds" };
public EuchreDeck() : base(values, suits) // Error.
{}
...
}
I want the ability to instantiate EuchreDeck and have the two string
arrays passed to the base class, i.e. var gameDeck = new EuchreDeck();.
Currently I'm getting the error: "An object reference is required for the
non-static field, method, or property EuchreDeck.values."
Is this possible, or will calling the derived default constructor always
call the base default constructor?

Good Coding Practice with Databases: One connection / query vs one connection / all queries
Good Coding Practice with Databases: One connection / query vs one
connection / all queries
So I am finding myself struggling which is the best practice. This is my
first time coding C# and first time coding anything in like a decade. Back
when I worked as a php / sql programmer, we usually frowned on the idea of
opening a new connection for every query, but the more I research this
question on google today, specifically with C# and sqlite, the more it
seems many recommend doing the polar opposite.
So, I was hoping the put this question out for some of you guys, who have
obviously been doing this a lot more than eye. Here is the general setup
of my database class:
class DatabaseController
{
static private SQLiteConnection _sqlconn;
static private string _uri;
public static SQLiteConnection Sqlconn
{
get { return DatabaseController._sqlconn; }
set { DatabaseController._sqlconn = value; }
}
public static string Uri
{
get { return DatabaseController._uri; }
set { DatabaseController._uri = value; }
}
}
The second class, which is the main Database class, which deals with
actually running queries and such. The reason I have the
DatabaseController class is because I can store the open connection handle
to the static member _sqlconn and so the connection is only ever opened
once, and Database objects simply use the same handle, even though the
program can and will create many Database objects.
But again, is this actually necessary? Should I simply be opening a new
connection within the main Database class, every time an object is
created? There was another site and thread I found that apparently, what
the .NET Framework does is even though you maintains a connection pool for
you, so even though you might be opening and disposing of several
connections, they aren't truly closed. Is this truly so, and does that
apply to both desktop and windows 8 apps?

Backbone google map suggestions on implementing markers
Backbone google map suggestions on implementing markers
Hello stackoverflow community,
I am trying to get may hands dirty with google maps and backbone together.
All is going very well with both. I just have one slight issue I am
slightly stumped on. I have a backbone view for my map, which looks like
this:
var MapWidget = Backbone.View.extend({
el: '.map-widget',
model: new Model,
center: function (e) {
},
addMarker: function () {
},
render: function() {
this.map = new google.maps.Map(this.el, this.model.attributes);
this.bindings();
console.log('Map Widget Rendered');
return this;
},
initialize: function() {
console.log('Map Widget initialized');
}
});
here is the model:
var MapWidget = Backbone.Model.extend({
defaults: {
zoom: 8,
center: new google.maps.LatLng(39.23036, -94.48182),
mapTypeId: google.maps.MapTypeId.ROADMAP,
disableDefaultUI: true
},
initialize: function(){
}
});
As you can see all the maps options are pulled from the maps model. What i
am struggled to figure out(or organize) is, if I start to add markers to
my map should the markers be stored in the same map model or should the
markers have their own collection? If i should have a collection of
markers, would it make more sense then to have a markerLoader view that
added the markers to the map from its own marker collection?
I hope all that make sense, just looking for some advice from some
seasoned backbone guys or anyone looking to add there two cents.let me
know if i need to explain more. Thank you stackoverflow community

Django fails to find R when loading RPy2 under virtualenv
Django fails to find R when loading RPy2 under virtualenv
This is kind of confusing, apologies in advance. I am configuring a new
(temporary) internal production web server with the following specs:
OSX 10.8.4 (Mountain Lion), Apache 2.2.25, PostgreSQL 9.2, Python 2.7.5,
Django 1.5.2, R 3.0.1, RPy2 2.3.7, virtualenv 1.10.4, virtualenvwrapper
4.1.1, mod_wsgi 3.4
This was set up on a new machine using Homebrew and pip. I removed
original, Apple-installed versions of Apache and Postgres before doing the
installs. Both Apache and mod_wsgi work. mod_wsgi is installed to run as
daemon process.
Virtual hosts is configured in Apache to access django via mod_wsgi and
the wsgi.py file contains the following lines:
import os,sys,site
site.addsitedir('/Users/kaiju/.virtualenvs/nauru_dev/lib/python2.7/site-packages')
# Activate the virtual environment
# Taken from
http://thecodeship.com/deployment/deploy-django-apache-virtualenv-and-mod_wsgi/
activate_env =
os.path.expanduser('/Users/kaiju/.virtualenvs/nauru_dev/bin/activate_this.py')
execfile(activate_env,dict(__file__=activate_env))
All python packages (including django and RPy2) have been installed using
the virtual environment's python site-packages.
R was installed using Homebrew and works fine from the command line or
from python interpreter when invoked within the virtual env (most of the
time, more later).
homebrew.mxcl.httpd.plist has been added to /Library/LaunchDaemons instead
of ~/Library/LaunchAgents so that it would automatically start when the
machine is rebooted. homebrew.mxcl.postgres.plist has been added to
~/Library/LaunchAgents (probably should also move it to
/Library/LaunchDaemons).
So here is the problem. When everything was installed, it worked together
fine. To verify everything was cool, I restarted the machine and tested
the django application. Apache is running, as is django, but now I get the
following error:
