Ranking a vector containing ties – mathematica.stackexchange.com
How can I rank a vector such that the ties are replaced by their middle
ranks. For example, {1, 2, 2, 3}. I want to rank this vector but the ties
must be replaced by their mid-rank; i.e., given {1, 2, …

Showing that the preimage of a continuous function on R is a รณ-algebra
Showing that the preimage of a continuous function on R is a ó-algebra
Let $f$ be a continuous function on $\mathbb{R}$. Define
$\mathcal{A}=\left \{ E\subseteq \mathbb{R} : f^{-1}(E)\in
\mathcal{B}(\mathbb{R})\right \}$.
I want to show that $\mathcal{A}$ is a $\sigma$-algebra.
I think I'm just being silly, but this exercise almost seems trivial to
me. I mean since $f$ is continuous, then for every open $E\subseteq
\mathbb{R}$ we know that $f^{-1}(E)$ is open in $\mathbb{R}$. Then
wouldn't $\emptyset, E^c \in \mathcal{A}$ if $E\in \mathcal{A}$, and that
$\mathcal{A}$ is closed under countable unions automatically follow? What
am I missing here?

Ambiguous error in inherite class c++
so i will give a small example of what is my problem,can someone help me
resolve this:
class A

can someone help me in this ambiguous problem,because i want to use the
function show() in all classes,and i didn't quite understand how to solve
this

Destroying controller in angular
Destroying controller in angular
I have a function like this, in an AngularJS controller
$timeout($scope.loadPosts, 5000); // pull every 5 seconds
When I navigate away from the controller (to another view), how can I stop
the timeout and eventually destroy the controller so it is not running
anymore?

How to design constructors?
How to design constructors?
Lets assume a class Foo with 2 instance variables, int x and int y. The
use case demands I can construct the class with either none, single or all
params.
input X input Y
0 0 no constuctor
0 1 public Foo(int x);
1 0 public Foo(int y);
1 1 public Foo(int x, int y);
Now whats the convention/best practices in this case. Do I need to add all
the permutations of constructors ? If yes, the it would result in
exponential growth. If No, then whats solution ?

I'm having a lot of difficulty with this problem and was hoping someone

Most popular, extensible wiki?
Most popular, extensible wiki?
I am trying to find a wiki, preferably open source, that I can easily
extend programmatically. xwiki (though Java/groovy based) seems a bit
clumsy to me. Just discovered twiki and love it (though Perl is not my
language of choice).
Problem is, I looked up a bunch of wikis on google trends and it seems
that twiki is way past its popularity peak. Something must have "stolen"
its market share, but what? Confluence has risen, but it's commercial and
a paid product. Anything else?

Path aliasing for static resources in Spring dispatcher servlet
I have a Spring Web app where the dispatcher servlet is only used for
static files. There also is a Jersey servlet for API calls from
JavaScript, mapped on another URL pattern, not too relevant to my problem.
At the moment my entire dispatcher configuration looks like this:
@Configuration
@EnableWebMvc
public class DispatcherConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/**").addResourceLocations(
"classpath:/www/");
}
}
There is a main.html file right under www in my classpath. If a request
comes in for /main.html, the file is served correctly. Great.
Now, I would like this same file to be returned for requests on /, /part
and a bunch other paths. Basically, I want some kind of path aliasing
here, or direct mapping from path to file. How can I achieve it?

OpenFileDialog - Check if has not been selected
OpenFileDialog - Check if has not been selected
I am working on a procedure to Open a file from Excel. I want to insert a
check, if the user presses Open without selecting a file, then have a
message box pop warning.
Here is a portion of my code where I want to insert the check. I tried
using Is Nothing, but it did not work for me.
If GetOpenFileName.ShowDialog() =
System.Windows.Forms.DialogResult.OK Then
fileStream = GetOpenFileName.OpenFile()
If (fileStream Is Nothing) Then 'I tried checking here,
but it does not fire.
vmbContinue = MsgBox(strAlert, MsgBoxStyle.RetryCancel
+ MsgBoxStyle.Critical, "No Workbook Seletected")
If vmbContinue = MsgBoxResult.Cancel Then
xlWB.Close(SaveChanges:=False)
Exit Sub

Approach to Incrementally Index Database Data from Multi-Table Join in Lucene with No Unique Key
Approach to Incrementally Index Database Data from Multi-Table Join in
Lucene with No Unique Key
I have a particular SQL join such that:
select DISTINCT ... 100 columns
from ... 10 tabes, some left joins
Currently I export the result of this query to XML using Toad (I'll query
it straight from Java later). I use Java to parse the XML file, and I use
Lucene (Java) to index it and to search the Lucene index. This works
great: I get results 6-10 times faster than querying it from the database.
I need to think of a way to incrementally update this index when the data
in the database changes.
Because I am joining tables (especially left joins) I'm not sure I can get
a unique business key combination to do an incremental update. On the
other hand, because I am using DISTINCT, I know that every single field is
a unique combination. Given this information, I thought I could put the
hashCode of a document as a field of the document, and call updateDocument
on the IndexWriter like this:
public static void addDoc(IndexWriter w, Row row) throws IOException {
//Row is simply a java representation of a single row from the above
query
Document document = new Document();
document.add(new StringField("fieldA", row.fieldA, Field.Store.YES));
...
String hashCode = String.valueOf(document.hashCode());
document.add(new StringField("HASH", hashCode, Field.Store.YES));
w.updateDocument(new Term("HASH", hashCode), document);
}
Then I realized that updateDocument was actually deleting the document
with the matching hash code and adding the identical document again, so
this wasn't of any use.
What is the way to approach this?

How can I speed up this SQL view?
I'm a beginner at this so hope you can help. I'm working in SQL server
2008R2 and have a view that is comprised from four tables all joined
together:
SELECT DISTINCT ad.award_id,
bl.funding_id,
bl.budget_line,
dd4.monthnumberofyear AS month,
dd4.yearcalendar AS year,
CASE
WHEN frb.full_value IS NULL THEN '0'
ELSE frb.full_value
END AS Expenditure_value,
bl.budget_id,
frb.accode,
'Actual' AS Type
FROM dw.dbo.dimdate5 AS dd4
LEFT OUTER JOIN dbo.award_data AS ad
ON dd4.fulldate BETWEEN ad.usethisstartdate AND
ad.usethisenddate
LEFT OUTER JOIN dbo.budget_line AS bl
ON bl.award_id = ad.award_id
LEFT OUTER JOIN dw.dbo.fctresearchbalances AS frb
ON frb.el3 = bl.award_id
AND frb.element4groupidnew = bl.budget_line
AND dd4.yearfiscal = frb.yr
AND dd4.monthnumberfiscal = frb.period
The view has 9 columns and 1.5 million rows and growing. A select * from
this view was taking 20 minutes for all the rows. I added indexes on the
fields in the tables that are joined on and that improved it to 10
minutes. My question is what else could I do to get the select to run
faster?
Many thanks, Violet.

Get UTC date of last commit
Get UTC date of last commit
I'm trying to put together a bash/sh script that gets the UTC time of the
last commit from a svn repo (the other VCSs are easy) I understand that i
can just do svn propget --revprop -rHEAD svn:date and get it rather
easily, but there is no guarantee that the svn checkout will be online, so
I'd prefer an offline version, if possible.
Maybe something to do with getting the UTC time from svn info? (by
screwing with the timezones)

MeasureString length is different from CSS Width
MeasureString length is different from CSS Width
I have a program that let's users create a canvas and drag/drop/resize
text onto that canvas using jquery ui. I submit the CSS & DOM details via
JSON to the server to draw these out and return a pdf. I also scale up the
size of the canvas and all related elements to draw them at higher
resolution using the GDI in .NET.
This all works great, except around line-height. This is defined in the
CSS as the same as the font-size in px. So, when I draw text, I split the
text string and draw word by assembling a line and then moving to the next
one by the font size. I do this word by word and measure the string
against the text's parent div's width. 99% this works, but occasionally
there is a difference when the word is wrapped in my calculation and what
is in the browser (screenshot below).
I've added a 1% buffer to the width in .NET to catch these, but there is
always a slight discrepancy that seems to change depending on the font.
Is there a way I can preserve the same wrap in browser in .NET? Is there a
better way to draw out text than what I am doing? Can I change CSS to act
more like .NET in the word wrap detection? This seems like a minor
problem, but clients expect parity between what they create and what gets
generated, so I'm going nuts here trying to find a good solution. I'm open
to anything, thanks!
Example Pic: The word 'pick' wraps onto the next line when I draw it in
.NET. The right side is the editor in the browser, while the rendered
result is on the left.

I have a program that let's users create a canvas and drag/drop/resize
text onto that canvas using jquery ui. I submit the CSS & DOM details via
JSON to the server to draw these out and return a pdf. I also scale up the
size of the canvas and all related elements to draw them at higher
resolution using the GDI in .NET.
This all works great, except around line-height. This is defined in the
CSS as the same as the font-size in px. So, when I draw text, I split the
text string and draw word by assembling a line and then moving to the next
one by the font size. I do this word by word and measure the string
against the text's parent div's width. 99% this works, but occasionally
there is a difference when the word is wrapped in my calculation and what
is in the browser (screenshot below).
I've added a 1% buffer to the width in .NET to catch these, but there is
always a slight discrepancy that seems to change depending on the font.
Is there a way I can preserve the same wrap in browser in .NET? Is there a
better way to draw out text than what I am doing? Can I change CSS to act
more like .NET in the word wrap detection? This seems like a minor
problem, but clients expect parity between what they create and what gets
generated, so I'm going nuts here trying to find a good solution. I'm open
to anything, thanks!
Example Pic: The word 'pick' wraps onto the next line when I draw it in
.NET. The right side is the editor in the browser, while the rendered
result is on the left.
.NET code:

How to get Openid for google account
How to get Openid for google account
I am developing a Spring MVC webapp that has Spring security enabled. I am
trying to use OpenID to use gmail login for access to the webapp given
instructions here.
I want only a specific set of users to have access to webapp. For this, I
would be required to add all the users and their ID's to tag. (Later will
implement a DB access for this)
My question is: How can I find the OpenID for my gmail account that will
be used to access the webapp?
I understand that the OpenID is unique for each account and can be used
for local authorization. Please correct me if I am wrong.

mssql - select from another table if no results from the first table
mssql - select from another table if no results from the first table
I have to run a query to find a price. I have multiple price lists, each
in their own table. customer_price, default_price and minimum_price.
not all price lists have all the products and at times a product might not
appear on any price list and then the price needs to return 0 for the
price.
so I want to:
select price from customer_price where customer='walmart' and
product='whitebread'
if this returns a result then all is well. if the result is 0,NULL or the
query returns no rows I want this to run:
select price from default_price where customer='walmart' and
product='whitebread'
if this returns a result then all is well. if the result is 0,NULL or the
query returns no rows I want to simply return 0.
I am not sure how to proceed. I tried a case statement but the case
statement fails if no row is found in the results. how can I do this or
say if 0 results then
thanks in advance, as always.

Feed a stream into Uri
Feed a stream into Uri
I am using the MJpegDecoder from Coding4Fun to decompress a motion-jpeg
stream in a windows runtime based app.
For a project I need to compare TCP- with UDP-transmission. The decoder
expects a URI to the mjpeg source (for TCP streams it is http:// IpAdress
: PORT). now with message based UDP I was thinking about providing a
stream in which I write the single messages.
Question is:
Is it possible to get the Uri to an in-memory stream, without writing it
to a temporary file before?

Why does simplex noise seem to have *more* artifacts than classic Perlin noise?
Why does simplex noise seem to have *more* artifacts than classic Perlin
noise?
I read Stefan Gustavson's excellent paper on simplex noise, in which I was
promised that:
Simplex noise has no noticeable directional artifacts
in contrast with "classic" Perlin noise. I excitedly implemented it to
find out that the opposite appeared to be true. I do see artifacts in
classic noise, but I see at least as many artifacts in simplex noise,
aligned at 45 degrees to the main axes. They're especially noticeable when
you map the noise to a step function.
To ensure it wasn't a problem with my implementation, I used someone
else's JavaScript implementation. Compare some images:
Classic noise vs simplex noise
Classic noise step vs simplex noise step
And here's a gallery with all of them. In that last image, look for
borders that are aligned at 45 degrees from horizontal/vertical. They're
all over the place. I can highlight some of them if need be, but they seem
really obvious to me. (And again, I see them in the classic noise image as
well.)
Is this a problem with the simplex noise algorithm? Is it something that
can be fixed? Or am I the only one who sees this as a problem?

Why does TextReader.Read return an int, not a char?
Why does TextReader.Read return an int, not a char?
Consider the following code ( .Dump() in LinqPad simply writes to the
console):
var s = "��"; //3 byte code point. 4 byte UTF32 encoded
s.Dump();
s.Length.Dump(); // 2
TextReader sr = new StringReader("��");
int i;
while((i = sr.Read()) >= 0)
{
// notice here we are yielded two
// 2 byte values, but as ints
i.ToString("X").Dump(); // D852, DF62
}
Given the outcome above, why does TextReader.Read() return an int and not
a char. Under what circumstances might it read a value greater than 2
bytes?

how to configure mysql to accept local queries
how to configure mysql to accept local queries
Hi have a c++ application that makes queries to mysql database, I need to
run LOAD DATA LOCAL INFILE but if I do this from c++ it does not work...
right now I have it set using the username in my.cnf which is on default
(mysql)
#define USER "mysql"
#define PASSWD "jdhfa"
#define URL "tcp://10.3.21.49:3306"
if I use 127.0.0.1 in the url it will throw an error
Can't connect to MySQL server on '127.0.0.1' (111) (MySQL error code:
2003, SQLState: HY000 )
Server waiting for connections
In my.cnf I changed bind address to my IP becasue I need to access the
database from other places, but I still need to use it from my c++
program, I tried to add two bind-address statement
bind-address 10.3.21.49
bind-address 127.0.0.1
and this did not work.
I am not sure what else to do here??

How do I return a list of joined hibernate entities?
How do I return a list of joined hibernate entities?
Suppose I have a MySQL table, and entity tag in hibernate, where a tag is
a row in the following
id (primary key), tag, entity id
1, food, 77
2, shop, 98
3, food, 32
...
I'd like to return the total counts of the same tag sorted in decreasing
number of entries. Aka,
tag, count
food, 2
shop, 1
...
I was told to do something like
SELECT tag, COUNT(*) `count`
FROM table1
GROUP BY tag
ORDER BY `count` DESC
Output:
| TAG | COUNT |
|------|-------|
| food | 2 |
| shop | 1 |
However, how do I read this newly created list of entities out from
Hibernate? Do I need to somehow define a new object to read this list out?
The same question goes for say reading an entity (row) that is defined,
but just joined with another entity as part of a query. How do I read out
the result?
Thanks!

Facebook feed dialog - feed dialog not working as expected
Facebook feed dialog - feed dialog not working as expected
I have been trying this for the past couple of days but I couldn't get it
worked. I am trying to post on a users wall using feed dialog when he
enters an app for the first time using javascript SDK. Below is the code:
<div id="fb-root"></div>
<script type="text/javascript">
(function() {
var e = document.createElement('script');
e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
window.fbAsyncInit = function() {
FB._https = (window.location.protocol == "https:");
FB.init({
appId: '<?php echo $config["apikey"]; ?>',
frictionlessRequests : true,
status: true,
cookie: true,
oauth: true,
xfbml: true
});
FB.Event.subscribe('edge.create', function(href, widget) {
// Do something, e.g. track the click on the "Like" button here
addChipsLike();
});
};
var ffuname = '';
var lluname = '';
function post_to_wall()
{
FB.api('/me', function(response)
{
ffuname = response.first_name;
lluname = response.last_name;
});
//alert('inside');
FB.ui({
method: 'feed',
link: 'somelink',
picture: 'somepicture.png',
name: 'Name of the link',
caption: 'CaptDescription'
}, doitnow);
}
</script>
I check whether the user is new or not and if he is a new user I call the
post_to_wall() function inside php code.
The Problem is sometimes the feed dialog is loading but i couldn't get the
username, and sometimes the feed dialog is loading but "An error occurred.
Please try again later" in it and, sometimes the feed dialog is not at all
loading with an error in console, say "FB is not defined" in the line
FB.api.
Could anybody please help me to fix this issue? Thanks in advance...

is it possible to declare two application in AndroidManifest
is it possible to declare two application in AndroidManifest
the manifest is like this:
<manifest
<application
android:name=".MyApplication1" >
<MainActivity
...
</application>
<application
android:name=".MyApplication2" >
<MyService
android:process=":remote" />
</application>
actually, i want to fix a issue like this: if I declare service MyService,
which runs in a private process, whthin MyApplication1, then two instances
of MyApplication1 will be created, which means the initialization in
MyApplication1 will be done twice. So, i wanna to init a separate
application when MyService is to be launched by declaring MyService in a
separate application MyApplication2 as shown above in the manifest. But
unfortunately, it doesn't work as i think: MyService can not start at all.
have i omitted something, or made a fundamental mistake to try doing so?

JQuery Mobile and Firefox don't play well together?
JQuery Mobile and Firefox don't play well together?
Having some teething issues with jQuery Mobile. Was wondering if anybody
else is experiencing a smattering of errors when they're using Firefox
(desktop) and have the jQuery Mobile script includes in their <head> like
so:
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script
src="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.js"></script>
In both Chrome and Firefox I get a host of CSS errors, which I presume are
negligible. But in Firefox I get a couple of JS errors on top of that,
which also seems to break my page (responsive elements not rendering like
they would when I remove the jQuery Mobile script).
The JS errors:
Empty string passed to getElementById(). @
http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.js:11100
Use of getPreventDefault() is deprecated. Use defaultPrevented instead. @
http://code.jquery.com/jquery-1.9.1.js:3346
I know the errors seem pretty verbose, but I'm not familiar with bloaty
javascript plugins and their policy on graceful degradation. Anyone else
having this issue?

Icon little issue
Icon little issue
Finally the hour has come, the release folder is not empty now, the last
touches are done. I've noticed this behavior and was wondering if someone
else had this problem and how to solve it:
Ok here.
Ok here.
Not okey here.
The icon comes with a variety of sizes, and it is set as resource in VS
solution.
It's not very important but it gives a very poor image of the app. Is
there any easy solution?

parse byte count in ftp log
parse byte count in ftp log
I'm running on an arm architecture. Should be a bash script. I would like
to graph total bytes coming and out of my ftp server.
I parse the ftp.log file with this command to get this output:
`cat ftp.log | grep loaded`
the interesting lines are in this format:
Sep 14 18:46:00 sharecenter pure-ftpd: (doc@omega) [NOTICE]
/mnt/HD/HD_a2//SAVE/backupffp.sh downloaded (423 bytes, 0.78KB/sec) Sep 15
22:06:47 sharecenter pure-ftpd: (doc@omega) [NOTICE]
/mnt/HD/HD_a2//SAVE/ffp-2013-09-14.tar.bz2 downloaded (904753213 bytes,
1928.17KB/sec) Sep 15 22:32:26 sharecenter pure-ftpd: (doc@omega) [NOTICE]
/mnt/HD/HD_a2//SAVE/test.avi uploaded (576711530 bytes, 1465.80KB/sec)
Now I need to get the values after the "(" and before the word "bytes" and
add them.
Example:
--> downloaded 423+904753213=904753636 => returned value: 904753636
--> uploaded 576711530 => returned value: 576711530
Now the script will run every 5 minutes, so the result has to take into
account only the numbers between the last 5 minutes. Example: At 22:05
script runs and adds all bytes. When script runs again at 22:10 only the
transfered bytes between 22:05 to 22:10 should be added.
For rrd you need a simple output, 2 variables "dowloaded" and "uploaded".
So I will need those 2 values in those 2 variables.
I hope I am clear enough, if not don't hesitate to ask for more information.
Many thanks for your help.

Multiple Web Sites/Roles on Azure, Impact of staging server
Multiple Web Sites/Roles on Azure, Impact of staging server
I'm looking to set up two web roles or websites on my Azure Cloud Service.
The websites need to share the same database schema. I use NHibernate ORM,
so I have to make sure that both projects are always using the same data
model, or else it will cause major problems.
I've researched setting up multiple websites on a single web role (which
seems odd to me, can't I just run multiple web roles, each with a single
site)?
http://msdn.microsoft.com/en-us/library/windowsazure/gg433110.aspx
Like any good developer, I use a staging server. If I have to manually set
the domain name is configuration files, how will azure know not to be
sending people who visit that domain to the staging server?! I.E. If they
visit blah.foo.com and I have two deployments (staging and production), is
IIS going to be able to know only to send people to the production
environment?
Please advise on the best way to go about doing this.

C++: Reading data from a memory mapped file
C++: Reading data from a memory mapped file
I have used MapVirtualFile to map a file under Window using C++ VS2010.
I would now like to fill a structure with the data.
I have been using
void clsMapping::FeedPitchmarksFromMap(udtPitchmarks &uAudioInfo,unsigned
long int uByteStart)
{
unsigned long int iCountPM;
memcpy(&iCountPM, &((char*)(m_pVoiceData))[uBytePos],sizeof(int));
uAudioInfo.Pitchmarks.resize(iCountPM);
for (unsigned long int i=0;i<iCountPM;i++)
{
iBytePos+=sizeof(int);
unsigned long int iByteStart;
memcpy(&iByteStart, &((char*)(m_pVoiceData))[iBytePos],4);
iBytePos+=sizeof(int);
unsigned long int iByteCount;
memcpy(&iByteCount, &((char*)(m_pVoiceData))[iBytePos],4);
iBytePos+=sizeof(int);
unsigned int iF0;
memcpy(&iF0, &((char*)(m_pVoiceData))[iBytePos],4);
uAudioInfo.Pitchmarks[i].ByteStart =iByteStart;
uAudioInfo.Pitchmarks[i].ByteCount =iByteCount;
uAudioInfo.Pitchmarks[i].F0 =iF0;
}
}
As one can see, I am currently using memcpy to get the data. Is there a
faster way to do "get my data over"?

How to create separate model for each user type in Laravel
How to create separate model for each user type in Laravel
I have the basic User model that deals with the users table, I have two
types of users, each type has different attributes and reads those
attributes form a different database.
User: name, email, type (x,y)
type_x: gender, age
type_y: color, location
So I have the user table, the type_x table, and the type_y table.
How can I create three different models, User, Typex, and Typey so that I
can retrieve the data of each model in a different way and dealing with a
different table?

Get only random 20% of consecutive inputs
Get only random 20% of consecutive inputs
I have a system that constantly gathers items from a rss feed.
I want to take only a certain percentage, say 20%, of those items, randomly.
My approach is that for each item I "throw a dice" using rand(0,100) and
accept the item only if the result of this statement is < 20.
Is it a good approach?

I am trying to retrieve image paths from SQLite database and display
corresponding images on the ImageView. The problem is, helper class is not

The queries are working fine, when I test them on SQLite browser I don't
have any problem with queries. I have checked the database file in
/data/data/com.example.myappname/databases/ folder. I have the required
photos in /storage/sdcard/DCIM/Camera/SAMPLE IMAGES/.
The path this function is returning is, /storage/sdcard/DCIM/Camera/SAMPLE

/storage/sdcard/DCIM/Camera/SAMPLE IMAGES/xxx.png
The string "xxx.png" is stored in database and with the query GET_SD, I am
retrieving the name of the image.
I have checked many questions and tutorials on this, but didn't get
solution for this.Please suggest me some solution. Thanks in advance.

For example, the description of /lib/ is that it contents shared library

What exactly is a library? Are we talking about library files similarly to

they used for?
What relation does it have to a .dll

How to avoid this error?
Kernel Level Event Detection
Kernel Level Event Detection
Is it possible to detect an event occurring in an application on Kernel
level?
For example, I have a very simple program that takes two input numbers,
adds them and displays the result. I wish to build another program which
detects when the addition in the first program is complete - This is an
event detection in some sense. (it does not wish the result, just needs to
know when the additon is done).
Now I do not wish to modify my first application to "send" some kind of
response when it is done adding. Is there some way I can contact the
kernel to notify me, when this particular application performs an
"addition", and I use this as proof that the addition has occured ?
(This may not be the best example, but I hope you get the idea. Another
example could be that I wish to detect when a browser (Chrome for e.g.)
has finished downloading a file, so I can sync it to my dropbox. Assume
that chrome fires no event on download complete and that I want to do it
without modifying the Chrome source code.)
Also, I wish to do it on Kernel Level because I wish the event detection
to be language independent. However, if there is any such feature in any
particular language, I would be interested in knowing it as well.
Any response would be appreciated. Thanks.

WP7 Map Application with Multiple TileSources
WP7 Map Application with Multiple TileSources
I'm developing a C# map application for Windows Phone 7 using custom
MapTileSources. I'm wondering if I can have multiple map layers, so that
each of them binds to a different MapTileSource. The idea is that the
first layer contains the ground map and the layers above that would
represents routes and other information on top of the ground map. The
layers above should be partially transparent. Is this possible and any
ideas how this could be done?

How do I tell sbt to publish a zip instead of a jar?
How do I tell sbt to publish a zip instead of a jar?
SBT docs describe how to publish to a maven repo:
http://www.scala-sbt.org/release/docs/Detailed-Topics/Publishing
I want to publish just the contents of the src/main/resources folder and I
want to publish a zip instead of a jar.
Can I do this without adding an sbt plugin?

Post http python
Post http python
The below python script, when run, produces an HTML file. When the user
clicks on "submit your request", the big textarea below it is filled with
parameters that I want to send to another python script. Currently the
only way I can get it to work is to paste the textarea to the textbox at
the bottom, and press Enter.
I would like to kill the bottom texbox, and get the "submit your request"
to send the content of the area box.
Please help, I have spent countless hours today and its driving me crazy.

Windows Service starting/stopping another service
Windows Service starting/stopping another service
I have a slight problem with a service I have written in C++. The service
itself functions correctly and is running under the SYSTEM account. During
one point of execution, I have to start or stop another service. This,
however, is not working. The call to OpenService() returns error code 5,
which is "Access denied".
To give a little bit more detail: I have to start an own time provider
service that tries to open port 123 on a network adapter, and this port is
often already opened by the win32time Service from Windows. What I try to
do is to give the user the option to automatically stop this service when
my service is starting, and starting it again when it stops.
This service can only be accessed with elevated user privileges on systems
that are UAC-capable, I know that, but I always thought that the SYSTEM
account would be able to perform this action by default, but apparently I
am wrong.
Is it possible somehow to elevate my service (maybe by adapting the
privilege level in the manifest to 'requireAdministrator' or something
similar)? I haven't tried this yet to be honest, since I fear that the UAC
prompt will be stuck in session 0 or things the like. Or is there another
way to grant my service running under SYSTEM the privileges to control
another service's status?
Any suggestions are very much appreciates, thanks!
EDIT
Okay, here's the code, and I feel a little bit stupid now... I have
totally forgotten to check the API thoroughly, because I thought that the
last parameter of OpenService() can be zero to request all privileges by
default, but I have to pass SC_MANAGER_ALL_ACCESS. Sorry for bothering
everybody. I will try this tomorrow and close this question when I have
the results.
SC_HANDLE scm = OpenSCManager(nullptr, nullptr, SC_MANAGER_CREATE_SERVICE) ;

I have checked my table that if I am committing any errors in the
uppercase and lowercase thing but its perfectly fine cos I have stored all
the information in the table after converting it into lowercase. Has it
got something to do with the function retrieve()? PS: I will change the
functions to mysqli() once this script works Thanks in advance
I have this piece of code, which should retrieve the value from the
database and then print in on the page, I have created links that will
pass value to the page and then I retrieve the value from GET and the
result should be printed, but is it happening? NO!, I am not getting any
errors on the page, rather I am getting nothing on the result page cos its
a blank page.

Table parameters or xml data type
Table parameters or xml data type
I have a store procedure with 50 parameters and may be increased in future.
I know I can pass less parameter if I use a string xml or table parameter.
And I'm confusing .Should I use xml or table parameters ?
Anybody , Please help me choose the best solution. Thank you.

selectOneMenu not populating another selectOneMenu using ajax listener
selectOneMenu not populating another selectOneMenu using ajax listener
I am using two selectOneMenu. Selection of first one should populates the
second one by providing the selected value as a parameter. I have gone
through a lot of online stuff but still not find a way to resolve it. The
listener method is getting called on dropdown value change. Someone please
help me out.
<p:selectOneMenu value="#{myBean.mGroup}" id="mGroup" style="width:130px;" >
<f:selectItem itemLabel="Environment" itemValue="E"></f:selectItem>
<f:selectItem itemLabel="Health" itemValue="H"></f:selectItem>
<f:selectItem itemLabel="Physical" itemValue="P"></f:selectItem>
<p:ajax update="mClass" listener="#{myBean.mGroupChangedListener}" />
</p:selectOneMenu>
<p:selectOneMenu id="mClass" style="width: 130px;" value="#{myBean.mClass}">
<!-- <f:selectItem itemLabel="Temp1" itemValue="Temp1" /> if i
remove comment from this line, it works -->
<f:selectItems value="#{smyBean.mClassList}" var="clas"
itemLabel="#{clas.mClassDesc}" itemValue="#{clas.mClassId}" />
</p:selectOneMenu>
// listener method
public void mGroupChangedListener(AjaxBehaviorEvent event) {
List<MClass> mClassList =
service.getMClass(event.getComponent().getAttributes().get("value").toString());
myBean.setMClassList(mClassList);
}
