(using Pagedown AKA WMD Editor) | I'm experiencing a really odd error in Pagedown (AKA WMD Editor, the open-source version of the markdown editor used here on StackOverflow), but I think someone with the proper JS experience could help me without actual knowledge of Pagedown.
The "insert link" and "insert image" buttons put a shaded background over the page when they are clicked. This is then removed by code `background.parentNode.removeChild(background);` where `background` is a variable that was set earlier, and references the `div` that holds the background.
At times, when the background is obviously visible in the page, the code above fails, and the browser console says `Uncaught TypeError: Cannot read property 'parentNode' of null` except that I have verified that `background` at that exact time is NOT null.
Note that when I say "at times", it is actually always the second time clicking the button. (i.e. click insert button, cancel, click insert button again, try canceling again........instant failure.)
Can anyone take a guess as to how/why this is happening? I don't have any "hacks" in place that could be causing this, but I am using the "hooks" feature which I'd guess is not often used. | javascript | wmd | null | null | null | null | open | Why is parentNode sometimes null?

static char* KCmdA = "commandA"
static char* KCmdB = "commandB"
static char* KCmdC = "commandC"
In C I can compare two strings with strcmp(A, B) for example but as I only refer those command via their static string identifier it's faster to only check for pointer inequality since I know my unknowCMD can only be a pointer to one of my static strings.
switch(unknowCMD)
{
case KCmdA:
...
case KCmdB:
...
}
I guess in Java the equivalent to strcmp would be the method equals:
unknowCMD.equals(KCmdA)
Is there an equivalent of the pointer equality in Java ? I know Java uses only references. Is it possible to use those references for equality test without actually comparing the strings ?
Sorry if this is obvious I've check the doc but did not find any definitive answer.

The child model has an attribute which is manipulated in logic as an array, but is serialized to a YAML string using the Rails built-in serialize method.
Within the form, I display each individual member of the array so that the user can selectively delete members.
The problem happens when the user destroys all members. The form will not pass any value for the param to the Rails controller and when the UPDATE action is called, it ignores the attribute since there is no key for it in the forms params hash. This is of course a known problem with things like checkboxes, so Rails automatically puts 2 checkbox HTML elements for each checkbox, one hidden that only processes if the checkbox is checked off.
I'm not dealing with checkboxes here but rather hidden input text fields.
The solution I've implemented is to manipulate the params hash directly in the UPDATE action of the controller, like this:
params[:series][:time_slots_attributes].each { |k,v| v[:exdates] ||= [] }
Is this considered code smell?
Should I instead add an extra hidden field that is disabled and only gets enabled when the user removes the last member? This solution works as well, but it seems clunky to me. | html | ruby-on-rails | ruby-on-rails-3 | forms | null | null | open | Is directly manipulating the Rails form params hash considered code smell?

Could someone please clarify some questions for the below scenario. Excuse me if it is very basic
1. I'm writing a proprietary software in which i plan to use some open source libraries. I will also need glibc and a C compiler, but did not want to use the default gcc toolchain from my OS, so built my own using crosstools-ng
2. Now in ct-ng, i guess the glibc library gets linked statically. If that is the case, given that glibc is LGPL, and that i can link it to my proprietary software, will this static linking cause any issues to me wrt licensing? Can my software still be close sourced? or do i have to release the compiled objects. If that is the case, if i rebuild the toolchain to make link glibc link dynamically i wouldn't have to release my compiled objects?

the links do appear on the bottom of the page where i place the function that calls the pagination.
when clicked, the page does nothing.
Ive found countless similar questions on the web (many here on SO ) but when i try to implement
those posts resolutions, the same thing happens. ALL the different pagination methods,loops,functions....and EVEN plugins that i try WORK in that they **appear** on the page but when clicked, the url changes accordingly but the page content doesn't change.
So as an example, im using this loop that i found in an "accepted answer" from someone elses question here on SO
function pagination($pages = '', $range = 3){
$showitems = ($range * 2)+1;
global $paged; if(empty($paged)) $paged = 1;
if($pages == '') {
global $wp_query; $pages = $wp_query->max_num_pages; if(!$pages)

}
if(1 != $pages) { echo "<div class='pagination'><span>Page ".$paged." of ".$pages."</span>";
if($paged > 2 && $paged > $range+1 && $showitems < $pages) {

if ($paged < $pages-1 && $paged+$range-1 < $pages && $showitems < $pages) echo "<a href='".get_pagenum_link($pages)."'>Last »</a>";
echo "</div>n"; }
}
and applied the function call to the bottom of my post loop under the endwhile//if so that it doesnt repeat through each post shown on the page, and again, it shows (just like all the others)
but the page itself doesnt do anything.
My question is, with this type of a problem where the links are showing up and all types of different versions ive tried, **do** appear on the page but when clicked, go nowhere, what is it i could be missing???
do i need to enable pagination somewhere like the way one enables widgets or..or do my pages have to have any type of hook or ..... like when one inserts "**<?php wp_head(); ?>**" etc...
im at a loss.

print $command."\n";
$result = `$command`;
print "->".$result."\n";
For this I get

I want to do a script to automate this since a lot of this has to be done. However, a very special set of environment variables among other things are setup to make 'wpj'. If I call wpj with backquotes from Perl, the call fails. You can see the code below
$command = "wpj add library path\\to\\file.wpj \\path\\to\\add";
print $command."\n";
$result = `$command`;
print "->".$result."\n";
For this I get
wpj: not found
However, the same call from the shell succeeds. Something is not correctly exported, could you please give me suggestions on how to export the calling enviroment into the subshell created by backquoutes? thank you.

Let me try to explain:
I have an object called Task, the task can be done either by a user and a group of users.
so I have the tables: tasks, users, groups and taskowners.
The taskowners has these fields: id_task, id_owner, typeofowner(which is 1 for groups and 2 for users).
Could you give me an example of how to construct this model in cakephp?
I am kinda new to it.
Or should I create tasks, users, groups, taskgroups and taskusers? Theorically, the task can be owned only by these two, but I don't know if there will be more in the future, thats why the generic connection table.
Thanks,

===
I am new to javascript and Raphael.js so bare with me please. I am working on a project that requires a circular user interface. The interface will be created using Raphael.js to create rings(donut chart style) with each section being a menu item. When selected the a new ring will be generated with the number of selections needed for the next task.
So the problem I have is creating the actual javascript class to do this. As separate functions it works great but it's not very efficient. How do I call the new object and get the ring to show up on the screen? here is the code i am using:
var paper = Raphael('paper', 600, 600);
function RingObj(centerX, centerY, innerR, outerR, startAngle, endAngle, sections) {
this.centerX = centerX;
this.centerY = centerY;
this.innerR = innerR;
this.outerR = outerR;
this.startAngle = startAngle;
this.endAngle = endAngle;
this.sections = sections;
this.donutRing = function(){
this.endAngle = 360 / this.sections;
this.endAng = this.endAngle;
paper.setStart();
for (i = 1; i <= this.sections; i++){
this.arc = function(){
radians = Math.PI / 180,
largeArc = +(this.endAngle - this.startAngle > 180);
outerX1 = this.centerX + this.outerR * Math.cos((this.startAngle-90) * radians),
outerY1 = this.centerY + this.outerR * Math.sin((this.startAngle-90) * radians),
outerX2 = this.centerX + this.outerR * Math.cos((this.endAngle-90) * radians),
outerY2 = this.centerY + this.outerR * Math.sin((this.endAngle-90) * radians),
innerX1 = this.centerX + this.innerR * Math.cos((this.endAngle-90) * radians),
innerY1 = this.centerY + this.innerR * Math.sin((this.endAngle-90) * radians),
innerX2 = this.centerX + this.innerR * Math.cos((this.startAngle-90) * radians),
innerY2 = this.centerY + this.innerR * Math.sin((this.startAngle-90) * radians);
// build the path array
this.path = [
["M", outerX1, outerY1], //move to the start point
["A", outerR, outerR, 0, largeArc, 1, outerX2, outerY2],
["L", innerX1, innerY1],
["A", innerR, innerR, 0, largeArc, 0, innerX2, innerY2],

];
return this.path;
};
this.ringpath = paper.path(this.arc);
this.startAngle = this.endAngle;
this.endAngle = this.endAngle + this.endAng;
}

I have delayed tasks that slurp data from the web and create records in a PostgreSQL database. They seem to be working okay, but they start at vmemsize=100M and within ten minutes bulk up to vmemsize=500M and just keeps growing. My MacBook Pro with 8G of RAM starts thrashing when the VM runs out.
How can I find where the memory is going?
Before you refer me to other SO posts on the topic:
I've added the following to my #after(job) method:
def after(job)
clss = [Object, String, Array, Hash, ActiveRecord::Base, ActiveRecord::Relation]
clss.each {|cls| object_report(cls, " pre-gc")}
ObjectSpace.each_object(ActiveRecord::Relation).each(&:reset)
GC.start
clss.each {|cls| object_report(cls, "post-gc")}
end
def object_report(cls, msg)
log(sprintf("%s: %9d %s", msg, ObjectSpace.each_object(cls).count, cls))
end
It reports usage on the fundamental classes, explicitly resets ActiveRecord::Relation objects (suggested by [this SO post](http://stackoverflow.com/questions/11149837)), explicitly does a GC (as suggested by [this SO post](http://stackoverflow.com/questions/7278454)), and reports on how many Objects / Strings / Arrays / Hashes, etc there are (as suggested by [this SO post](http://stackoverflow.com/questions/3839262/)). For what it's worth, none of those classes are growing significantly. (Are there other classes I should be looking at? But wouldn't that be reflected in the number of Objects anyway?)
I can't use [memprof](https://github.com/ice799/memprof) because I'm running Ruby 1.9.
And there are other tools that I'd consider if I were running on Linux, but I'm on OS X.

class Tvshow(models.Model):
pass
class Season(models.Model):
tvshow = models.ForeignKey(Tvshow)
class Episode(models.Model):
season = models.ForeignKey(Season)
A tvshow has seasons, and a season has episodes. I left all other info out for simplicity.
My detail view for any of these objects can now handle any model by using DetailView. But I would also like to display the relations for an object, either parents or children. Let's say you are viewing a tvshow. I can't call on tvshow.season_set.all() to display this information because my template doesn't know it's dealing with a tvshow (nor that tvshows have seasons). Instead, I would like to be able to do this:
object.children_set.all().
That way I can feed my view any of these 3 models, and it will work. Is this possible?
p.s. I know the object. part works, but will the children part work also? There is one ugly hack I was able to come up with: use the relation_name property to name all relations children. I suppose it would work but it is not a direction I want to take.

===
I am trying to rewrite my Django code to make it as generic as possible on all levels. Say I have the following models:
class Tvshow(models.Model):
pass
class Season(models.Model):
tvshow = models.ForeignKey(Tvshow)
class Episode(models.Model):
season = models.ForeignKey(Season)
A tvshow has seasons, and a season has episodes. I left all other info out for simplicity.
My detail view for any of these objects can now handle any model by using DetailView. But I would also like to display the relations for an object, either parents or children. Let's say you are viewing a tvshow. I can't call on tvshow.season_set.all() to display this information because my template doesn't know it's dealing with a tvshow (nor that tvshows have seasons). Instead, I would like to be able to do this:
object.children_set.all().
That way I can feed my view any of these 3 models, and it will work. Is this possible?
p.s. I know the object. part works, but will the children part work also? There is one ugly hack I was able to come up with: use the relation_name property to name all relations children. I suppose it would work but it is not a direction I want to take.
views.py:
from django.views.generic.detail import DetailView
class ObjectDetailView(DetailView):
template_name = "detail.html"
urls.py
from tvshows.views import ObjectDetailView
from tvshows.models import Tvshow
urlpatterns = patterns('tvshows.views',
url(r'^(?P<pk>\d+)/$', ObjectDetailView.as_view(model = Tvshow), name='detail'),

| c | visual-studio | null | null | null | null | open | error in compiling a C code for householder reduction algorithm
===
I wrote a C code for householder reduction (convert a matrix to a tridiagonal matrix), but for compiling it gives the following error:
First-chance exception at 0x0139399d in eig3.exe: 0xC0000005: Access violation reading location 0x001ac240.
Unhandled exception at 0x0139399d in eig3.exe: 0xC0000005: Access violation reading location 0x001ac240.
I don't know what the cause of this error is and how to handle it.
Thanks for any help.

I have been toying around with the app by adding extra features such as Photo uploads, Twitter-user sign-in etc etc. I was wondering whether there are in another Rails resources out there that use Hartl's project-based approach towards learning.
I was directed towards `Rails for Zombies` and found it to be very limited and big step back after Hartl. I was suggested `Rails 3 in Action by Ryan Bigg and Yehuda Katz.`
Would be grateful if you any of you could provide me with some `project-based learning` resources for Rails.

d <- data.frame(v1 = c("A","A","A","B","B","B","C","C","C"),
v2 = c(1:9), stringsAsFactors = FALSE)
What I want is to compare the values of A against values of B. Also values of A against values of B and as a last comparison the values of B against the values of C
I constructed 2 for loops to iterate over v1 to extract the groups to compare. However, the for-loops give me all possible combinations like:
A vs. A
A vs. B
A vs. C
B vs. A
B vs. B
B vs. C
C vs. A and so on...
Here are my for-loops:
for(i in unique(d$v1)) {
for(j in unique(d$v1)) {
cat("i = ", i, "j = ", j, "\n")
group1 <- d[which(d$v1 == i), ]
group2 <- d[which(d$v1 == j), ]
print(group1)
print(group2)
cat("---------------------\n\n")
}
}
How can I manage to only iterate over data frame `d` so that in the first iteration group1 contains the values of A and group2 contains the values of B. In the second iteration group1 contains the values of A and group2 the values of C. And as a last comparisons group1 contains values of B and group2 contains values of C.
I am somehow totally stuck with that problem and hoping to find an answer here.
Cheers!

So that's the code and I'm just wondering why it produces that pop-up box. I can't see any logic errors in the code itself.
P.S. I have modified the URLs so you can't see where they actually go. Project is very hush hush ;)![The Pop Up Error message when I click a button][1]

===
I'm fairly new to this android stuff but I'm building a small app that when you press a button you can go to a specific URL (goes to an optimized version of a website). I've encountered a problem however. The application complies and loads onto the AVD but the only button which provides any response is the first one and the response it produces is a pop-up error message saying (Unfortunately, MyApplication has stopped.) and closes the application. The other buttons do not respond to a click. See code below.

I am using MVVMLight with a WP7 app. I have created a Main view connected to a viewmodel. This main view has a number of of custom controls that i created. Now from my understanding each usercontrol must have its own individual viewmodel.
SO i have my main view datacontext connected to its viewmodel and every usercontrol's datacontext pointing to its own viewmodel.
Problem is, how do i get access to my viewmodel data from my custom controls in my viewmodel for my main view.
I am a little confused.
I could use the messenger but this sounds way too much work just to get the viewmodels communication.
If anyone can lend a hand it would be really helpful or if anyone has any examples.

It works as expected for the most part, but recently I've had 2 overseas orders come through that haven't been charged shipping (one to Germany and one to Sweden).
When viewing the orders in the backend, Magento seems to think that shipping was charged, but when PayPal is checked, it confirms that no shipping was charged. Obviously, the figure charged in PayPal is the Magento figure minus the shipping figure.
I have absolutely no idea why this is happening, but my client is worried about it understandably. This question has been [asked before][1] but there were no replies.

Being able to do this will allow us to make much fewer calls the the DB, but I'm not sure how to fill the returned type I've created. Here's a poorly designed table structure that demonstrates what I'm trying to accomplish.
create table emp_group (
gid number,
gname varchar2(10)
);
create table emp (
empID number,
gid number,
empname varchar2(10)
);
create or replace type t_emp as table of emp%rowtype;
create or replace type t_group_emp
(
gid emp_group.gid%type,
gname emp_group.gname%type,
g_emps t_emp
);
We have two tables, one a list of employees and one a list of employee groups. Ignore the fact that there should be a join table between emp_group and emp so that an employee can belong to more than one group... demo code. 8)
I would like to return all of the employees for a given group ID, along with the groups row, in a single returned type. The returned type is t_group_emp, which has a table of emp rows.
I do get a compilation warning on the creation of the t_emp type. I'll edit the code if I sort that out.
1) Is this possible?
2) How would I structure the select statement to fill the returned type? Is 'bulk collect' the correct method here? I found [this page][1] to be a good starting point.
3) How poorly will this perform? I can run my own numbers once I get the syntax sorted, but overall, is this a good approach to returning data from multiple tables with a 1-N relationship?
It will be easy to code the application to consume the returned type, so I'm not worried about that.
edit: we're using Oracle 10.3.something...
Thanks

(The format of a key is directly linded to the type of object stored in the map - hence the map is of <String, Object>)
Three different actions are possible on the map : add, get, remove.
I secured the access to the map by using a public entry point method (no intense access) :
public Object doAction(String actionType, String key, Object data){
Object myObj = null;
if (actionType.equalsIgnorecase("ADD"){
addDataToMyMap(key,data);
} else if (actionType.equalsIgnorecase("GET"){
myObj = getDataFromMyMap(key);
} else if (actionType.equalsIgnorecase("REM"){
removeDataFromMyMap(key);
}
return myObj;
}
Do you confirm it is thread safe for concurrent access to the map since there is no other way to use map but through that method ?
If it is safge for a Map, I guess this principle could be applied to any other kind of shared ressource.
Many thanks in advance for your answers.

It contains roughly 3500 rows and 10 columns and takes over a minute to display the contents. Everything points the the fact that it is not doing UI virtualization of the data. However, I can't figure out why that is the case.
I am not using grouping.
I have made sure the grid's height is contained by placing it in a panel with a fixed height.
I have set all the virtualization properties on the DataGrid.
I have checked in snoop and these properties are set. However, snoop also shows that after loading there are several thousand datagridrows in the visual tree. Whether this is something that is caused by using snoop I have no idea.
I have tried using AQTime to find out what is going on. The slowdown does not appear to be in our code but in system code. However, I can't find a way of easily seeing what WPF is up to.
I have stripped down the grid and have tried both the .Net 4 DataGrid and the toolkit DataGrid. Both are unacceptably slow to show the initial data.
I have tried fixing the row height and column widths. This also makes no difference.
How can I confirm that virtualisation is on and if is is off why it is off?
How can I debug what is happening outside of our code? Is there any way of seeing what WPF is up to? (I've tried using the WPF Performance suite, but for some reason it does not give any output for our application).
I'm running out of ideas. It should not be this slow, when only 10 rows are visible in the UI.
Can anyone help?
