I started reading about IP after I finished and apparently I narrowly escaped some trouble. I did some freelance work for which I signed a restrictive contract that would've required me to fork over any rights to any software I wrote. I didn't develop any new code for the work, I only used code I already had, so I didn't have an issue. However, it got me thinking and kind of scares me out of doing any future work.
In my case, the code of my own I used was Python, so I think the issue of ownership would be relatively clear cut. But it got my thinking how IP would work for Javascript, which (for the most part) is intended to be downloaded and executed on every computer that wants to use the script. In terms of other copyrightables, I can't think of anything to compare this to. It'd be like Coke selling their products with the recipe printed on the bottle, but even more difficult, since at least in that case you'd have the physical evidence of who came up with it first. Due to the rapidity of propagation on the Internet, it seems like it'd be much harder to make the claim of originality, unless you went through the trouble of registering your copyright (or however that works).
So my question is how the copyright on client-side code can possibly be enforced. What if you developed such code for a client, who now holds the right to it but uses it on a public website, and you want to use pieces of it in a future project for your own purposes or for another client? Would it be illegal to use it without licensing it back from your former client? I doubt most bits of Javascript are worth worrying about, but I can imagine such an issue arising if you develop a neat jQuery plugin for a stingy client.
(Also, has anyone actually been forced to license their own code from a former client? Does that even make sense? I mean, you can't pretend you can't do something you've already done, so what prevents you from rewriting some code you've already come up with, even if you don't copy it verbatim?)
Sorry if my understanding of IP is naive and incomplete! Coding's my hobby not my job, and unless I hear some positive responses about this subject, I think it'll stay that way.
(Ps, I read some related questions on this forum, where many people replied "Don't rely on us for legal advice!" I wouldn't and won't and don't want to. I don't need legal advice, at least not yet. I'm trying to get the perspective of programmers with experience working with these issues, in case I decide to do more paid work in the future.) | javascript | copyright | null | null | null | 04/14/2012 00:18:32 | off topic | Clarification of copyright law on javascript code (enforceability, &c)

When a option is picked up from the drop down "marketingProgramArticleId", an onchange event is called which calls the managed bean method manageMarketingProgramsBean.populateMarketingProgramData which will populate some more form data in the same portlet and reloads the same portlet program.xhtml. When the portlet tries to reload as a result of selecting an option I am getting the following exception:

But when the portlet is loaded for the first time, everything works fine. The issue is after the onChange event on the drop down which the causes the portlet to be reloaded.

Here is my portlet named program.xhtml:

jQuery(document).ready(function()

var formID = clientId + '\\:associateMarketingProgramForm';
var formIDToFind = '#' + formID;
jQuery(formIDToFind+"\\:marketingProgramArticleId").change(function()

jQuery(formIDToFind+"\\:getMarketingProgramAssoc").click();

When a option is picked up from the drop down "marketingProgramArticleId", an onchange event is called which calls the managed bean method manageMarketingProgramsBean.populateMarketingProgramData which will populate some more form data in the same portlet and reloads the same portlet program.xhtml. When the portlet tries to reload as a result of selecting an option I am getting the following exception:

And the second group will then merge the changes into the NBT release as well.
Allegedly, this is to help the NBT team better plan the NBT - by having their developers not being distracted by customers, planning how much of their attention can be paid to the NBT product is theoretically easier. It also is supposed to help customers by having developers specialise in supporting customers.
What are your thoughts/experiences on such a split? Would you prefer this model? Would it cause you to look for further employment elsewhere? What are the pros and cons?
In my experience so far, I'm finding that:

===
At $work, we've recently (as in three or four years ago now) split our development organisation in two (but not half): one group to develop the Next Big Thing (NBT), and the other group to handle customer-reported problems, diagnose them, and check in the fixes for the regularly-scheduled patches (development support, or DS). And the second group will then merge the changes into the NBT release as well.
Allegedly, this is to help the NBT team better plan the NBT - by having their developers not being distracted by customers, planning how much of their attention can be paid to the NBT product is theoretically easier. It also is supposed to help customers by having developers specialise in supporting customers.
What are your thoughts/experiences on such a split? Would you prefer this model? Would it cause you to look for further employment elsewhere? What are the pros and cons?
In my experience so far, I'm finding that:
* some people have quit (or, rather, forced their manager to lay them off) Others seem to prefer this (I'm not sure why)
* the NBT group is further removed from customers resulting in:
* less understanding of what pain points customers really have

(assuming, the bullet will fire at 0 degree)
I did a lot of research and already dove into the physics laws of newton etc.
Basic applyforce does not seem to do the job accurate enough.
I also found the formula which calculates the needed velocity for an object to stay in orbit, and I managed to make this happen within box2d. However, if I want to stop the bullet, the bullet will not fall on earth again. (apply force is used for radial gravity and the second apply force is used to move the bullet to the "right" ) It will stay in orbit. Only if I add damping, the bullet will fall back to earth, but this seems wrong to me. When the bullet collides with something else, it also will damp.
i tought that the main issue here is to modify the velocity for the bullet. The bullet takes an x amount of time to land on lets say: 180 degree. How further away the bullet is from earth surface, the more velocity it takes to land on 180 degree the same amount of time. I think that velocity is the key to make true accurate radial gravity, but my question is; is this true, what do you guys think, does anyone have a similar scenario??
How does one control speed in the most proper way, without using damping and setlinearvelocity??
I also want to be able to control the speed needed to let the bullet orbit, escape or land back on earth. This should be possible, since there is also a formula that calculates the orbit velocity.
E.g. When it goes wrong, the bullet is moving too fast, will escape from earth, but will move back, because earth gravity will modify the path of the bullet.
Btw: i did search a lot on internet, but cannot really link that stuff to practical box2d code, so i hope, someone can point me the right direction.
Kind regards!

When i rotate my phone, the label of the button changes to "@23232324" which is the number of the resource.

Essentially, I would like to provide a service to "my" users that would let them easily create a site that includes blogging and some other specialized functionality while allowing them to maintain their own users. The best analogy is that I'd like to create a site similar to WordPress.com (the service, not the software), TypePad, or Blogger but way simpler (I'm only one guy after all!) and designed for users in a very specific niche.
Which brings me to my question: **what tools exist to help develop multi-tenant, multi-user web applications?** I would personally prefer something open source and written in .NET, but for the benefit of everyone else I think non-open source and/or non-.NET systems would also prove valuable. My first thought was to look for open source CMS systems that support multi-tenancy and have a robust extension mechanism. The most promising that I've found so far is [Orchard][1]. Has anyone used it (or something similar) for this kind of purpose?
My main requirements are (and these are general enough that I think many folks with similar host-type web application ideas may benefit from an answer):
- Multi-site/multi-tenant
- Allow the creation of multiple sites that are fully customizable (such as themes) but that share a common set of overall features and functionality.
- User management
- Support for "master" users that can configure the entire ecosystem.
- Support for "administrators" that have control over their own site and users, but not those of others.
- Support for "users" that are tied to an individual site, possibly with multiple access levels or types (as defined by the site's administrator).
- Extensibility
- Since the whole point is to provide a hosting application for individual sites in a specific niche, the setup has to be highly extensible to support additional features, changes to the platform, etc.
(I asked this over at Web Applications, but got closed as off-topic. Hopefully SO is the right site this time. Forgive me if not - it can be difficult to determine the appropriate SE site sometimes).

Xaml code is included 1:1 into the binary toolkit dll. It means it must be parsed at run-time.
Why to hell must every WP7 user again and again wait for parsing of meaningless white space? Just because of stupid formatting MS programmers use.
If these programmers read another [MS article][1] they would understand the amount of unnecessary work caused by inapropriate formatting. Plus there are articles on the web that prove that xml white-space parsing has non-negligible impact.
Sorry, had to write this as I daily see inefficient programming on the MS side. But nobody cares, so I decided to pick up a tiny water-proof example.
Wouldn't be bad to see the reaction of the toolkit authors.

Here is a tiny part of WP7 toolkit xaml code (copy-pasted):
<ColorAnimation
Storyboard.TargetName="SwitchBottom"
Storyboard.TargetProperty="(Grid.Background).(SolidColorBrush.Color)"
Duration="0"
To="{StaticResource PhoneForegroundColor}"/>
Here is the same code formatted differently:
<ColorAnimation Storyboard.TargetName="SwitchBottom" Storyboard.TargetProperty="(Grid.Background).(SolidColorBrush.Color)" Duration="0" To="{StaticResource PhoneForegroundColor}"/>
First code takes 402 By, the second is more than 2x smaller - 182 By. (If you wanted to properly format it, it would be stil 2x smaller.)

I have a UIViewController, viewControllerBrowse, with two TableViewController, Designations & Types, I call a second UIViewController, viewControllerSelectLibrary, that makes some SOLite operations and fills two arrays from where the first two TableView feed.
When I'm going to call back viewControllerBrowse, I perform inside a NSThread:
> Blockquote
[appDelegate.viewControllerBrowse.tvcTypes.tableView reloadData];
[appDelegate.viewControllerBrowse.tvcTypes.tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:YES scrollPosition:UITableViewScrollPositionTop];
[appDelegate.viewControllerBrowse.tvcDesignations.tableView reloadData];
[appDelegate.viewControllerBrowse.tvcDesignations.tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:YES scrollPosition:UITableViewScrollPositionTop];
What TRUUUULY puzzles me is that on tvcTypes case, its tableView gets its first row selected and scrolled to the top
BUT, for tvcDesignations, its tableView get ITS FIRST ROW SELECTED BUT IT DOES NOT SCROLL TO THE TOP
the fact that the first row is selected tells me that it's not a problem of reference in the appDelegate, it's as if only half the method is working/??????????????
anyone hit this one before??????

I am testing a server and client i made on my webspace.
when i try to call a simple "testServer" function defined in a ServerMap class, I get
"Looks like we got no XML document"
..?
I called getFunctions on the client and testServer is a valid function. I tried catching all exceptions and then calling __getLastResponseHeaders() and __getLastResponse.

static int A[3][2] = { { 1, 2 }, { 3, 4 }, { 5, 6 } };
That's fine and I can access all the members of it. However I have several problems passing it to a function, e.g.:
void print_matrix(int **a, int r, int c)
{
int x, y;
for(x = 0; x < r; x++)
{
printf("Row %02d = %#x = ", x, a[x]);
for(y = 0; y < c; y++)
{
printf("%s%d", (0 == y) ? "" : ", ", a[x][y]);
}
printf("\n");
}
}
Firstly I can't simply pass `A` to the function, I need to cast it to (int **). Since `char *` is synonymous to `char []`, I was a little surprised at this. Secondly, it crashes and when I check in the debugger, within the sub-function, `a[0]` is reported as `1` and not a pointer to an array of integers.
I know there is compiler/C language arcane magic happening here. But it is all a little confusing. If I try to initialise as:
static int *A[3] = { { 1, 2 }, { 3, 4 }, { 5, 6 } };
I get a ton of warnings. How does this differ to:
static char *S[3] = { "hello". "there", "stackoverflow" };
-----
Apart from the question of arcane C magic, which somehow I have never learnt despite over a decade of C programming :(, I would like to know how to generate my array so I can successfully pass it as an `int **` without having to go through all the fag of for loops or copying the statically allocated array to a dynamically allocated one.
Would the following work?
int *A0 = { 1, 2 };
int *A1 = { 3, 4 };
int *A2 = { 5, 6 };
int **A = { A0, A1, A2 };
Is there a nicer way than this of doing it?
Thanks, all.
P.s. I know that in real life we would read values from a DB or file into dynamically allocated arrays and avoid all this stuff.

I had to make an application and got an application ID and secret from that.

Is it that I must have been the person who "created" the community page or what?

The trouble is that each image load takes up a http request and most browsers have a limit on how many requests can be made to one hostname in parallel.
What this means is after typing the first letter into search the script will immediately fetch 20 images (for example), but this exceeds the parallel http requests limit which means an immediate subsequent letter press does not carry out the ajax instantly. Instead it waits in queue until the previous images have loaded. Only then will the search update.
This is very frustrating for the user, especially considering that the images I'm using are quite large in file size.
The only way I have found to overcome this is to place the javascript on a separate sub domain to the images, then JS loads instantly without waiting for images to load. However this is not a solution I can use in this project.

I seem to have an issue wich i cannot resolve.
Example;
I have a div with a gradient from white to gray. In this div there is a image with a outerglow (css). This image needs his right top corner 'cut off' with an angle of 45 degr.
Not a big issue one might think. Put a transparant image with a colored corner over it, or use css3. But the problem is the gradient. At the bottom there's the gray color. If you use the image with a colored corner, the colors won't match anymore. I can't use the css3 border radius because of IE/older browsers.
Is there a way to 'physically' cut off the corner with jQuery? The website is in ASP.NET C# so csharp solution would also work.
