Update to the database error when enter more than 1 value
i have a problem, the program just read the first entered Quantity value
in the program and apply it to all rows in database and the value of first
and second row are same, even though in the beginning, first and second
row value are different.
Note: The Database 1 until 1.3 and Program 1 until 1.2 are working
properly, i just want to show you to not confuse you later. My problem is
on Database 1.5 and Program 1.4 , Database 1.6 are just wanted to show
you, the Database supposed to be like that.
First of all, my database is like this:
Product Code || Quantity (Database 1)
0001 100
0002 150
And when i run the program and entered the first "Product Code" in first
row and want to change the first Quantity value to 25, so i just enter 75
in Quantity in the program at the first row like this:
Product Code || Quantity (Program 1, 0001 is at the **first row**)
0001 75
And when i click update, the database changed to this (it works fine):
Product Code || Quantity (Database 1.1)
0001 25
0002 150
When i change the first "Product Code" in first row to second "Product
Code" in first row and want to change the second Quantity value to 100, so
i just enter 50 in Quantity in the program in the first row like this:
Product Code || Quantity (Program 1.2, 0002 still at the **first row**)
0002 50
And when i click update, the database changed to this (it works fine):
Product Code || Quantity (Database 1.3)
0001 25
0002 100
But, when i enter the first "Product Code" in first row and second
"Product code in second row in my program like this:
Product Code || Quantity (Program 1.4, 0001 at **first row** and 0002 at
**second row**)
0001 10
0002 25
And when i click update, the database changed to this (it supposed to be
like Database below):
Product Code || Quantity (Database 1.6)
0001 15
0002 85
But instead of the Database above, it changed to this (it is not working
like i want):
Product Code || Quantity (Database 1.5)
0001 15
0002 15
So, it is like the second row at the database are being ignored and
changed to the same value like in the first row, when i enter both value
at the same time in the program.
Here is the code:
private void UpdateQuantity()
{
int codeValue = 0;
int index = 0;
List<int> integers = new List<int>();
foreach (var tb in textBoxCodeContainer)
{
if (int.TryParse(tb.Text, out codeValue))
{
integers.Add(codeValue);
}
}
using (OleDbConnection conn = new
OleDbConnection(connectionString))
{
conn.Open();
string commandSelect = "SELECT [Quantity], [Description],
[Price] FROM [Seranne] WHERE [Code] = @Code";
string commandUpdate = "UPDATE [Seranne] SET [Quantity] =
@Quantity WHERE [Code] IN(" + string.Join(", ", integers)
+ ")";
using (OleDbCommand cmdSelect = new
OleDbCommand(commandSelect, conn))
using (OleDbCommand cmdUpdate = new
OleDbCommand(commandUpdate, conn))
{
cmdSelect.Parameters.Add("Code",
System.Data.OleDb.OleDbType.Integer);
cmdSelect.Parameters["Code"].Value =
this.textBoxCodeContainer[index].Text;
cmdUpdate.Parameters.Add("Quantity",
System.Data.OleDb.OleDbType.Integer);
using (OleDbDataReader dReader =
cmdSelect.ExecuteReader())
{
while (dReader.Read())
{
if (textBoxQuantityContainer[index].Value != 0)
{
newVal =
Convert.ToInt32(dReader["Quantity"].ToString())
- textBoxQuantityContainer[index].Value;
cmdUpdate.Parameters["Quantity"].Value =
newVal;
int numberOfRows =
cmdUpdate.ExecuteNonQuery();
}
index += 1;
}
dReader.Close();
}
}
conn.Close();
}
}
Could you guys please help me? Thanks.

Arithmetic expression grammar in prefix notation (Java Cup)
Arithmetic expression grammar in prefix notation (Java Cup)
I'm writting a grammar for arithmetic expression in prefix notation.
However I have an issue when parsing negative numbers or substraction.
Grammar example is this:
precedence right +, -;
precedence right *, /;
precedence right uminus;
E ::= + E E
| - E E
| * E E
| / E E
| ( E )
| - E %prec uminus
| id
| digit
;
But if my input is - 5 4, it reduces 5 as E, next it reduces - E
(negative) and then parser gives me a syntax error at 4. The correct one
should be 5 as E, next 4 as E and then - E E as E. How can I solve this
problem using associativity? or do I need to rewrite my grammar?

JavaScript->CSS: display="";?
JavaScript->CSS: display="";?
In JavaScript, one can set the default display of an element by using the
following code outline:
whateverElement.style.display="";
If whateverElement's display was "none" when this code was run, it will
now be whatever it would be naturally, according to the browser's default
rendering.
If whateverElement was a DIV with no previous matched CSS rules that
define its display, when it's JavaScript display property is set to ""
(blank), its display would be defaulted to its natural, which is "block".
My problem is that I wish to use CSS3 animations by assigning a class to
them through JavaScript, some animations that make it necessary to know
the natural display of the element.
In Google Chrome Canary, I'm noticing that the display property "auto" is
non-existent.
Is there another way in which I can create CSS3 animations where I set the
display property to the "default" or "auto" display of an element?
Some examples...
div{display:inline;} //all divs to be displayed "inline"
div#specific{display:auto;} //#specific to be displayed BLOCK,
disregarding the previous CSS rule.

Miniprofiler gem generating a lot of 404 errors
The Miniprofiler gem for rails is very handy. (github, railscast)
However, I am getting a lot of 404 errors in my application:
In the chrome console, tab network:
Failed to load resource: the server responded with a status of 404 (Not
Found) http://localhost.mysite.com/mini-profiler-resources/results
This page returns the following response: Request not found: - user 127.0.0.1
On every page, I have 9 of those requests. (so it clogs my logs, and it's
annoying). And 9 more show up every time I trigger an ajax request.
It seems that mini profiler is trying to evaluate the time of a request
that doesn't happen... How can I troubleshoot this situation ?

Minimum height by css in html
Minimum height by css in html
I'm creating web site layout.
This is label3 css :
background-color:#c4efd5;
min-height:368px;
height:100%;
I want to set minimum height of lable3 to 368px even it does not contain
any data. And when I insert image height = 450px, label3 will be re-size
height to 450px.
I'm using min-height to do that, but it did not display as I expected.
Any answer will be appreciate. Thanks you.

Database operation in one go (one transcation)

I am working on a driver-booking management system. What I want to do is
that I need to add a driver in booking table (which means assigning a
booking to driver). Before that I need to check whether or not booking
record has driver record associated with or not (booking is assigned or
not), If yes then do nothing.
It works fine with one user doing this. But issue comes with multiple
users doing this on same record, same time.
How to handle this situation. I know about @transactional annotation. Is
that the right solution? Should I apply this on single method rather than
on my booking Assigning Service?
Using sync block would slow down processing alot, so currently I am
against this option

Perl regex: string literal containing metacharacters as variable for match expression
Perl regex: string literal containing metacharacters as variable for match
expression
I need to define a string literal as a variable which will be later used
as a match expression.
I want my variable $regex_op to match the string alt_id: ID: as well as
the string id: ID:.
my $regex_op = "(id|alt_id):\sID:";
my $searchword = "4";
Later on, I'm joining the variables in a regular expression:
/^($regex_op)($searchword)/m
Unfortunately, the whitespace wildcard \s is an "Unrecognized escape \s
passed through". The problem apparently consists in the string literal
containing backslashes (which are needed as part of the regex later on!).
Any ideas how to solve this?

Make vectors of unequal length equal in length by reducing the size of the largest ones
Make vectors of unequal length equal in length by reducing the size of the
largest ones
I am reading 6 columns from a .txt file to 6 vectors.
Sometimes some vectors are one element larger than others, so I need to
check if they are all of equal length, and if not, I have to find which
ones are the largest and delete their last element. I think I should be
able to do this without loops. I was originally thinking of using find in
combination with isequal but isequal only returns a logical, and does not
provide any information on which vectors are the largest.

I'm using preg_replace function to remove a list of stop words. Currently,
I have an array containing a lst of stop words. As the parameter for
preg_replace I use this as the first argument (i.e,
preg_replace(^$stopwordlist$, '',$string) As you can see I'm also using ^$
as I need to match word exactly.However I'm getting the following error
syntax error, unexpected '^', expecting ')' in
Thanks

Powershell Regular Expression?
Powershell Regular Expression?
So i have a log files that contains list of file that was copied from 1
folder to another folder.
For example,
12 Aug 17:23:51 C:\Users\Folder_1\File1.exe move to
D:\Users\Folder_1\File1.exe 12 Aug 17:24:33 C:\Users\Folder_2\File2.xml
move to D:\Users\Folder_1\File2.xml
so i wanted to to extract the 2 paths in the above line and write out into
another text file.
For example,
C:\Users\Folder_1\File1.exe D:\Users\Folder_1\File1.exe
I'm not sure how do i write the regular expression here. What i wanted to
achieve in the regex pattern is say C Drive, ignore the length of the
path, and exe files only. Tried something like "(C:\)(.exe)" , doesn't
work.
I would appreciate also if any1 can provide me with a list of special
characters for regex and their uses. For example /d means decimal /D not
Decimal etc. I still can't quite figure out what /< /> /b ? ! character
means though i still saw post of people using it.

Framework + DB + Server + Hardware?
Framework + DB + Server + Hardware?
I notice that I used the google translator for this question.
I have a project in mind. Perhaps not very large, but in order to learn.
I would like to create a social network, twitter style. People could post
and comment on it, change your profile picture, etc.
For a few weeks, I implemented a part with Symfony2 (PHP) + Bootstrap
(CSS) + MongoDB.
I used several symfony bundles such as FOS, but hey noticed that on many
occasions I had to reinvent the wheel (maybe for my ignorance) ...
I was reading about Ruby on Rails, and I was in love. In view is very
similar to twig, and models is easier than doctrine (which is not
difficult).
Going to the point.
What do you recommend to develop?
Ruby is a good candidate? What database do you recommend? (I think NoSQL)
Speaking in terms of hardware / server:
Debian 7 or CentOS? (Never used CentOS)
Tale with little money, and I'm the only effort in this project.
Eh just purchased the RAM (haha), but the following features are the ones
that I have in mind.
Intel Ivy Bridge Core i3 3220 2GB 1600Mhz Ram (for now) 1TB SATA3
(recommend SSD?) Asus P8B75-V Gen3

Distinct Clause in an SQL Query
Distinct Clause in an SQL Query
I have a table named MediaGenT in my SQL Database that has 425000 records.
However the column name mg_medianum has duplicate entries. For example
mg_medianum = '858' has 10 different records but I am only interested in
the most recent record which can be ordered by mg_createdate.
When I do this I get 425000 records:
Select * from MediaGenT
Order By mg_createdate;
When I do this I get 89000 records (correct but only shows one column):
Select distinct mg_medianum from MediaGenT
Order by mg_createdate;
To sum up what I need is one query that shows every column of the 89000
records only displaying the most recent distinct mg_medianum based ordered
by mg_createdate. I'm having trouble coming up with the syntax for that
kind of query.

Use variable to refer to contents of hash table
Use variable to refer to contents of hash table
I'm trying to refer to a hash table by name that is passed in via a
parameter.
Ex.
TestScript.Ps1 -specify TestDomain1,TestDomain2
param(
[string[]]$specify
)
$TestDomain = @{"Name" : "Test1", "Hour" : 1}
$TestDomain = @{"Name" : "Test2", "Hour" : 2}
foreach($a in $specify)
{
write-host $($a).Name
#This is where I would expect it to return the Name value contained in
the respective
# hash table. However when I do this, nothing is being returned
}
Is there another way to be doing this to get these values? Is there a
better method rather than using the hash tables? Any help would be
appreciated.

This happens when I embed it as an image as well as when I access it

but where is the use of DATABASE since the information will not be

are liked in a database. There will not be any tables.So, exactly How can

very clear but if someone can understand then please answer my question
its very urgent) Thank You.

and I wanted to have "Main Video" play with a picture in picture effect
with boxes of videos playing in the top left, top right and top mid. Each

Ransack search not working if there is 'space' in search term
Ransack search not working if there is 'space' in search term
I am using ransack for search in my rails 3.2 application using postgres
as database.
I have a Invoice model and every invoice belongs_to a buyer. Below is my
search form in index page.
views/invoices/index.html.erb
<%= search_form_for @search do |f| %>
<%= f.text_field :buyer_name_cont %>
<%= f.submit "Search"%>
<% end %>
And here is my controller code.
controllers/invoices_controller.rb
def index
@search = Invoice.search(params[:q])
@invoices=@search.result(:distinct => true).paginate(:page =>
params[:page], :per_page => GlobalConstants::PER_PAGE )
respond_to do |format|
format.html # index.html.erb
format.json { render json: @invoices }
end
end
Let's say a invoice is there of a buyer having name "Bat Man".
If I search "Bat", I get the invoice in results. Again if I search "Man",
I get the invoice in results. But if I search "Bat Man", I don't get the
invoice in results.
I know it might be something trivial but I am not able to resolve.
Please help.
Thanks.

HTTPS .htaccess Rewrite for parked domain
HTTPS .htaccess Rewrite for parked domain
I have two domain 'domain.in' and 'domain.com'. The domain.in is parked to
domain.com. I have SSL for domain.com So what I need is
1) If the user visit www.domain.com it should redirect to
https://www.domain.com
2) If the user visit www.domain.in it should use http.
I know this can done through '.htaccess' file.
Can any one help me for this issue ?

Load image from website
Load image from website
I am trying to add some chemical structure images to some plots I have
created. I am using the ACToR database to access the chemical structures.
For example:
http://actor.epa.gov/actor/image?format=png%3Aw250%2Ch250&casrn=80-05-7
The nice thing about this site is you can change the size and the chemical
within the url, so I can automate grabbing the images. My hope was to
store an object containing CAS numbers, then iterate through the CAS
numbers to make the plots.
For example:
library(png)
casnums <- ("80-05-7","77-40-7","1478-61-1")
image.list <- list()
for(cas in casnums){
image.list[[cas]] <-
readPNG(paste0("http://actor.epa.gov/actor/image?format=png%3Aw1000%2Ch1000&casrn=",cas))
}
I have tried using readPNG from the png package, and tried to use the
rgdal package as well. Unfortunately, as far as I can tell, ACToR will
only generate the images in a png or jpeg format - so I cannot use the
grImport package for reading vector images.
I am really hoping to find a solution where I do not have to manually
download each image - there are a lot of them. I would be open to a
solution where R goes and dowloads the images to a folder, then I could
use something like the png package, or the rgdal package to load the image
and plot them.

Breaking down a complex story at project start
Breaking down a complex story at project start
I'm trying to get to grips with agile project management (with Pivotal
Tracker) but keep finding myself running into walls when trying to define
the first few stories of a project. Take for example this very simple
story:
"A user should be able to tag a product"
Assuming I've already defined "product" elsewhere, this story would
possibly involve writing a polymorphic tagging system under the hood, on
completion of that system id be able to finally add the ability to tag a
product.
My problem is with the amount of work hidden in this story. I can define
tasks to get the story done but stories as a whole are supposed to be 1-2
days work? I don't feel right about the story just revealing the tip of
the iceberg but that's the only part that relates to the User.
How do you overcome this kind of thing? What are the best practices?

Qt PushButton Hover/Pressed icons
Qt PushButton Hover/Pressed icons
I'm beginning in Qt, and I want to set a QPushButton to a different icon
whenever somebody hovers the mouse over it. Here's my code so far:
#include <QPushButton>
QPushButton *button = new QPushButton(mainWindow);
button->setIcon(QIcon(":/icons/button.png"));
button->setIconSize(QSize(128,56);
button->setGeometry(0,0,128,56);
I've heard something about stylesheets, but I have no clue how to use them
and all the documentation is very confusing for me. Could somebody explain
how I can set the icon to ":/icons/button-hover.png" whenever the mouse
hovers on the button? Also, unless it's like exactly the same for when
it's pressed, it would be great if you could show me that too.
Thanks in advance :)

Use Star (*) with mysql inner join?
Use Star (*) with mysql inner join?
I have always done inner joins that look like this
SELECT Orders.OrderID, Customers.CustomerName, Orders.OrderDate
FROM Orders
INNER JOIN Customers
ON Orders.CustomerID=Customers.CustomerID;
Where you specify each row you want. I am currently working with a table
that has 50 rows however and I don't want to type all these SQL joins with
all the rows, is there a way to say "select * from Orders, then give me
Customers.CustomerName join on ...." instead of specifying every row from
the first table?

Exception instead of Compiler Error
Exception instead of Compiler Error
I expected this program to give me Compile error but it compiled
successfully and I got a runtime exception while running it.
class substr11
{
public static void main(String args[])
{
String s = "abcde";
System.out.println(s.substring(1,-1));
}
}
The compiler error should be able to parse (string is initialized in the
body itself) and find out that this string operation would result in
compile error right ?. Can someone tell me why it did not throw compile
error ?

Gwt - EditTextCell to look exactly like TextInputCell
Gwt - EditTextCell to look exactly like TextInputCell
I have cellTable (GWT) which uses TextInputCell to allow the user to Edit
cells. When a user first selects a textbox,it receives focus and the user
can edit the data. When the user then tries to select another textbox, the
previous textbox loses focus but the newly selected textbox does not
receive focus. Clicking on the box again gives it focus. EditTextCell does
the same functionality, it allows us to edit the cell in 1 click, but it
is difficult to identify the cell as editableuntil or unless you click on
it.
As shown in the showcase, Can we modify the existing EditTextCell to look
exactly like TextInputCell? Can somebody help me in modifying it?

How to make CFLAGS work with the dash shell?
How to make CFLAGS work with the dash shell?
My impression is that while setting the CFLAGS variable is effective when
bash is the default shell, it doesn't make an effect with dash (the Debian
Almquist shell).
First of all please correct me if my observation is wrong.
Secondly (if my observation is right), how can I get a global CFLAGS
variable effectively go through dash?
I've set the variable in ~/.profile like this:
export CFLAGS=-march=native

Python and Scheduling Computation
Python and Scheduling Computation
I wish to schedule a computation to occur after my current computation in
python is finished.
For example I am currently running:
>>> for i in range(2, 5):
... tn.TweetNetwork.create_subnetworks(i)
...
I made a simple mistake and meant to type range(1,5). This has been
running for at least 4 hours and should run for another few. That being
said I do not want to re-execute the loop with the correction and lose all
that has been computed.
As I am not by the computer 24/7, how can I schedule python to execute the
function `tn.TweetNetwork.create_subnetworks(1)?
I use emacs 24.3 and ubuntu 12.04 LTS, let me know if you need more
information. All help is greatly appreciated!

Performing a global lock in a Python web application?
Performing a global lock in a Python web application?
Basically, I have the following problem. There is a order processing
system which handles payments. In very rare circumstances, we end up with
double orders because while we query the credit card handler via the API,
if the user refreshes the page really quickly, the credit card processor
sometimes responds to both requests as "success" and we get two successful
"paid" events in the system.
So my idea was to implement a lock around the payment stuff (per order)
and if the lock is locked, tell the customer off (which would happen if
the customer refreshes the page very quickly - I think in our case it was
actually intentional).
So I thought about doing it with Redis and came up with this:
def _PaymentInterlock(object):
def __init__(self, pp):
self.key = GlobalKey('pay_ilk_%s'%pp._ident)
def lock(self):
self.key(1)
def unlock(self):
self.key.delete()
def try_lock(self):
result = self.key()
if result == 1:
return False
self.lock()
return True
The only problem with this is that the try_lock operation would not be
atomic (as opposed to a real compare and store operation), so technically,
two WSGI workers could get a key miss and then both lock the "lock"
causing the same sort of problem.
Are the any suggestions on how I would tackle this sort of a problem?

it could cost me loss of important data which is stored in home/username/

but it is showing that you don't have permissions to copy that. now my
problem could have multiple solutions such as-
1.>i can reinstall nvidia or integrated intel graphics driver so that i
can continue with my previous installation and data.
2.>i can copy the data to an external harddisk through commands (which i
don't know) and reinstall ubuntu(which i know :))
3.>i can copy the data though live ubuntu run through usb-stick to

similiar problems but none had worked yet.

I am looking for some solution for this: I need something like this:

Basically same effect like this: http://jsfiddle.net/RM3yr/2/
I can not JS, so I m looking for ready-made solution.
Thanks a lot

IIS Installation broken (reboot pending)
IIS Installation broken (reboot pending)
Every time i want to Install the IIS role on a server it reports the
following:
The request to add or remove features on the specific server failed.
The operation cannot be completed, because the server that you specified
requires a restart.
After a reboot the game starts again.
The IIS role WAS already installed on this server and got removed after
some configuration issues, I could not get rid of. No I am unable to
reinstall it again... Other roles on this Servers are: Domain Controller,
DNS, DHCP, NAP.
The ISS is used to invoke a DNS/DHCP Update Script from a web page to keep
DHCP and DNS entries on all servers up to date, and manage static entries
ect... (DHCP will be replaced soon by Microsoft own feature)
There are not entries in the eventlog regarding this error at all or which
could provide any useful data.
Any Ideas?
PS: (I Exported the configuration settings, but I relay have no Idea how
to use that XML file afterwards :)
EDIT: This Waring shows up 3 Times in the eventlog.
A provider, WebAdministrationProvider, has been registered in the Windows
Management Instrumentation namespace Root\WebAdministration to use the
LocalSystem account. This account is privileged and the provider may cause
a security violation if it does not correctly impersonate user requests.
And i just found this Logfile C:\Windows\Logs\CBS\CBS.log (it's a bit to
big for Pastebin, so i need to improvise) Part 2 Part 3 Part 4
Maybe this is helpful?

understanding this VB code
understanding this VB code
Can someone try wrap their brain around this one? I thought it was simply
ensuring there were 2 bytes in hex byte and ensuring the values were
between 0 -9 and A-F but no.
A snippet of a program that is for an infrared controller/blaster. This
subroutine will send the actual signals (or other codes) out the serial
port to the controller for it to finish the job.
Sample call:
SendCode ("04241001")
The VB6 code says:
Public Sub SendCode(ByVal strOut As String)
' ****************************
' This sub sends the hex codes
' ****************************
Dim numb1 As Integer, numb2 As Integer
Dim strRS As String
Dim i As Long
Dim newline(200) As String, outline(200) As String
Debug.Print "Sending IR - " & strOut
strRS = vbNullString
For i = 1 To Len(strOut)
newline(i) = Mid(strOut, i, 1)
Next
For i = 1 To Len(strOut) Step 2
If Asc(newline(i)) < 64 Then
numb1 = (Asc(newline(i)) - 48) * 16
strRS = strRS + Format(Hex(numb1 / 16), "0")
Else
numb1 = (Asc(newline(i)) - 55) * 16
strRS = strRS + Format(Hex(numb1 / 16), "0")
End If
If Asc(newline(i + 1)) < 64 Then
numb2 = (Asc(newline(i + 1)) - 48)
strRS = strRS + Format(Hex(numb2), "0")
Else
numb2 = (Asc(newline(i + 1)) - 55)
strRS = strRS + Format(Hex(numb2), "0")
End If
numb1 = numb1 + numb2
outline((i + 1) \ 2) = CByte(numb1)
strRS = strRS + " "
Next
With MSComm1
.RTSEnable = True
Sleep (20)
.OutBufferCount = 0
For i = 1 To (Len(strOut) / 2)
.Output = Chr(outline(i))
Next
Sleep (20)
.RTSEnable = False
End With
End Sub
The question is based around the second For/Next loop with Step 2 and the
embedded IF statements.

SQL Update a DateRange table from a SUM query of another table
SQL Update a DateRange table from a SUM query of another table
Table DateRangeTab (Fromdate, Todate, TotalValue) has data such as:
2010-01-01, 2011-01-01, 0
2010-01-01, 2012-01-01, 0
etc (i.e lots of date ranges all with 0 in the TotalValue column)
I also have table ValueTab (DateofValue, Value) which has data such as:
2010-01-02, £25
2011-01-01, £45
2011-05-04, £65
etc (i.e. lots of different rows with dates and a value for each date)
I need to update DateRangeTab TotalValue column with SUM of Value from
ValueTab table where the DateofValue falls in the range FromDate - Todate.
I tried something like the following :
Update DateRangeTab set TotalValue = a.Value from ( select sum(value) as
Value from ValueTab VT join DateRangeTab DT on VT.DateofValue between
DT.startdate and DT.ToDate) a
But it puts same total in each row of the DateRangeTab. Hope someone can
help or direct me to another post with a related answer.
Thanks

Operator precedence odd behaviour
Operator precedence odd behaviour
The reference I'm using for Ruby operators:
http://phrogz.net/programmingruby/language.html#table_18.4
According to this reference (and others I've seen), equality operators
take presendence over logical AND (&&, not Ruby's and).
So if we have the following:
foo = nil
foo < 5 # NoMethodError: undefined method `<' for nil:NilClass
# So to check for foo we do:
foo && (foo < 5) # Note the parenthesis
# But this works
foo && foo < 5 # why does this work??
In the last example foo && foo < 5, foo < 5 should happen first thus
resulting in an error before the AND can even be evaluated.
Am I missing something?

changes have been made. So my main question at hand is, how do I get this
to fully work without that mysql error message? Any help would be much
appreciated!

I have it working where a user is able to change/update their password,
however, when they click the Change button on the form, they are directed
to that error message I posted above, and if they click the refresh
button, only then they are redirected back to their profile and the
changes have been made. So my main question at hand is, how do I get this
to fully work without that mysql error message? Any help would be much
appreciated!

CGRectIntersectsRect() to detect first interseption
CGRectIntersectsRect() to detect first interseption
I use CGRectIntersectsRect()to see whenever a CCSprite collides with
another CCSprite:
- (void)update3
{
for (CCSprite *sprite in _monsters)
{
if (CGRectIntersectsRect(_rocket.boundingBox, sprite.boundingBox))
{
NSLog(@"Collide");
}
}
}
This fires the log as long as the sprites touches each other, I just want
to detect the first touch. Is this possible?

Fastest way to upload streaming points, and removing occasionally
Fastest way to upload streaming points, and removing occasionally
So i have a system (using OpenGL 4.x) where i am receiving a stream of
points (potentially with color and/or normal), from an external source.
And I need to draw these points as GL_POINTS, running custom switchable
shaders for coloring (color could be procedurally generated, or come from
vertex color or normal direction).
The stream consists of receiving a group of points (with or without normal
or color) of an arbitrary count (typical from 1k to 70k points) at a
fairly regular interval (4 to 10 hz), I need to add these points to my
current points and draw all the points so far received points.
I am guaranteed that my vertex type will not change, I am told at the
beginning of the streaming which to expect, so i am either using an
interleaved vertex with: pos+normal+color, pos+normal, pos+color, or just
pos.
My current solution is to allocate interleaved vertex VBOs (with
surrounding VAOs) of the appropriate vertex type at a config file
specified max vertex count (allocated with the DYNAMIC hint).
As new points come in i fill up my current non filled VBO via
glBufferSubData. I keep a count (activePoints) of how many vertices the
current frontier VBO has in it so far, and use glBufferSubData to fill in
a range starting with activePoints, if my current update group has more
vertices than can fit in my frontier buffer (since i limit the vertex
count per VBO), then i allocate a new VBO and fill the range starting at 0
and ending with the number of points left in my update group (not added to
the last buffer), if I still have points left I do this again and again.
It is rare that an update group straddles more than 2 buffers.
When rendering i render all my VBOs (-1) with a
glDrawArrays(m_DrawMode,0,numVertices), where numVertices is equal to max
buffer allowed size, and my frontier buffer with a
glDrawArrays(m_DrawMode,startElem,numElems) to account for it not being
completely filled with valid vertices.
Of course at some point I will have more points than I can draw
interactively, so i have an LRU mechanism that deallocates the oldest
(according to the LRU alg) sets of VBOs as needed.
Is there a more optimal method for doing this? Buffer orphaning? Streaming
hint? Map vs SubData? Something else?
The second issue is that i am now asked to removed points (at irregular
intervals), ranging from 10 to 2000 at a time. But these points are
irregularly spaced within the order I received them initially. I can find
out what offsets in which buffers they currently exit in, but its more of
a scattering than a range. I have been "removing them" by finding their
offsets into the right buffers and one by one calling glBufferSubData with
a range of 1 (its rare that they are beside each other in a buffer), and
changing there pos to be somewhere far off where they will never be seen.
Eventually i guess buffers should be deleted from these remove request
adding up, but I don't currently do that.
What would be a better way to handle that?
Thanks for any input.

Notification message tray?
Notification message tray?
Cinnamon desktop environment has a rather nifty idea of a tray in the
systray that holds all notification messages till their read and cleared,
and then becomes empty. How can I have the same thing in fluxbox please? I
think it needs to be done via a bash script but I haven't the faintest
idea where to start! This would be used on a debian testing machine under
fluxbox desktop environment, but would hopefully be usable under ones like
razor-qt as well.

I can read the line as a string but need to input the values into an

What is the splash range for throwing urine and milk?
The wiki doesn't seem to have much on the two splash weapons in game, Mad
Milk and Jarate, in terms of splash radius.
What's the splash radius on these two weapons in terms of units? Is the
splash radius effected by anything else, including height thrown from, or
the position landed? Is it a circular radius, or a spherical radius?

unable to boot chromiumos "vanilla" from hard drive
unable to boot chromiumos "vanilla" from hard drive
I'm at the end of my teather here.
I have a Thinkpad X220 (last year's model) which boots with EFI, and I'm
trying to install Chromium OS on it. Hexxeh's Vanilla usb image boots from
USB fine, and EVERYTHING works, even suspend.
I follow the instructions to install it to disk via the chrosh command
"install", everything goes ok. I reboot and am faced with the grub 1.97
sh.grub> prompt. all the text is orange rather than white, if it matters.
Typing ls yields just (hd0), no partitions (even though gparted says there
are all 12).
No messing around with grub works, because it doesn't recognise any
partitions, just the one disk, hd0.
The same USB image succsessfully installs chromiumos on an old non-efi
laptop I have lying around. I can only assume it is grub 1.97 not
supporting efi?
I would really like to know what's up, thanks in advance!

I've got a strange one. I'm using Django (version 1.5.2) and have my app

I keep getting emails about an unhandled exception from the following
user-agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; InfoPath.1;

The exception is caused by whatever that browser is adding trailing

For example I have an <img> tag in the body of my document, with src of

However, whatever browser that is adds up to three trailing slashes to
that URL, so the request is actually

Notice the three slashes in the URL. This causes an unhandled exception.
This app has its fair share of users, and it seems to only be this user

I'm wondering if this is a bug in the browser, or if it's something I'm
doing, and if anyone has seen this issue before.

Find nodes of the same height when a binary tree node is given?
Find nodes of the same height when a binary tree node is given?
I want to know if there is any other optimal solution than this.
Problem: Given a Node in a binary tree, I need to write a program to find
out all the nodes that are of the same level as the given node
(inclusive). Example: If the given node is of the level 2 then program
should return a collection of all the nodes with height 2.
My Solution : I had two methods, one to find out the root of the given
node and return the root(this method also finds out the height (bheight in
my code) from the node to the root) and this root is fed to the second
method to do a breadth first search and keep updating heights of the nodes
as I traverse and if the height of the first element in the queue equals
to the height that I calculated in the root method, then I return the
queue.
My Code:
import java.util.LinkedList;
import java.util.Queue;
public class binaryTree {
int value;
binaryTree left;
binaryTree right;
binaryTree parent;
int height;
static int bheight;
Queue<binaryTree> que = new LinkedList<binaryTree>();
public binaryTree(int v) {
value = v;
}
//This method returns a Queue of all the nodes that are on the same level
as the supplied node b.
public Queue<binaryTree> BFS(binaryTree b) {
b = root(b);
que.clear();
b.height=0;
que.add(b);
while (!que.isEmpty()) {
binaryTree node = que.remove();
if (node.left != null) {
node.left.height=(node.left.parent.height)+1;
System.out.println(node.left.value+" Root is
"+node.left.parent.value+" and its height is " +
node.left.height);
que.add(node.left);
}
if (node.right != null) {
node.right.height=(node.right.parent.height)+1;
System.out.println(node.right.value+" Root is
"+node.right.parent.value+" and its height is " +
node.left.height);
que.add(node.right);
}
if(que.peek().height==bheight)
{
break;
}
}
return que;
}
//Finds out the root of the given node and returns the root node

if (t.parent == null) {
return t;
} else {
bheight++;
return root(t.parent);
}
