Granted, GDI+ is still THE technology to handle Images in Windows, but it is also unmanaged code (obviously). Now, after discovering that GDI+ is actually not supported on ASP.net¹, I just wonder: Is it actually feasible to have Image Manipulation Libraries that run completely in Managed Code? XNA does it if i remember correctly, albeit it uses the graphics card for it.
Is there maybe even any .net Image Library that implements a sort of managed GDI+?
¹ [Source][1], also Microsoft just offered [something][2] for ASP.net that uses GDI+.

The value of code reuse is widely touted, and for good reason, but it does not come for free. Joel's <A href="http://www.joelonsoftware.com/articles/fog0000000007.html">In Defense of Not-Invented-Here Syndrome</a> makes the point that you don't always want to be at the mercy of outside entities.
I work in big science. Most projects have a few custom software tools (DAQ systems, analyzers, simulations, etc.) which are generally built using pretty well organized processes and decent coding practices. They also come with a raft of little tools, which are often banged up by one scientist, and put into productions with little of no processes at all.
Each of these tools need to do some of:
* Process options
* Read configuration files
* Extract metadata from other files
* ...etc...etc...etc...
This is a diverse and non-standardized hardware and software environment, and a coder can't make many assumptions about what tool/libraries/compilers a colleague will have (much less what version of each), so adding a dependency is fraught with danger and portability costs.
But rolling your own takes time, risks introducing untold numbers of bugs, and guarantees no one else will understand the tool.
So what goes into this decision?

During the course of my career, I have come across application that were heavily written in the database using stored procedures whereas a lot of application just had only a few basic stored procedures (to read, insert, edit and delete entity records) for each entity.
I have seen people argue saying that if you have paid for an enterprise database use its features extensively. Whereas a lot of "object oriented architects" told me its absolute crime to put anything more than necessary in the database and you should be able to drive the application using the methods on those classes?
Where do you think is the balance?

One of the things I implemented was a routing system. I used Apache's mod_rewrite to send all requests to index.php, and then parsed the URI to extract information and route the request.
I'm dabbling in ASP.NET now, and I'm wondering if/how I might perform something similar. Is there a way to route all requests (similar to the way WordPress does it) to one page where central route processing is performed? I'm aware of the MVC framework for ASP.NET, but I'd like to take a stab at this myself as I'm tinkering around and learning.

Even still, there are times I need to pick up a language relatively quickly for a new project I am working on. The point of this post is to document some of the best tutorials on the web for these languages. I will start the list with the best I can find, but hope you guys out there can help with better suggestions/new languages. Here is what I found:
C: [This][1] tutorial seems to pretty consise and thourough, looked over the material and seems to be pretty good. Not sure how friendly it would be to new programmers though.
C++: The tutorial on [cplusplus.com][2] seems to be the most complete. I found another tutorial [here][3] but it doesn't include topics like polymorphism, which I believe is essential. If you are coming from C, [this][4] tutorial might be the best for you.
Java: The official [Java tutorial][5] pages seem thourogh, but I am not a java expert. You guys know of any better ones?
Python: Don't know if there is anything better than the tutorials on the offical [python page]. If there are, please let me know.
Perl: I personally just used the perldoc perl and followed all the suggestions there, and I don't think you will be able to beat that. The best I found is [here][6].
Ruby: Found [this][7] site which gives a good description of 12 different ruby tutorials. Don't think I can do better than that.
Visual Basic: Found [this][8] site which seems to devote itself to visual basic tutorials. Not sure how good they are though.
php: Found a [simple tutorial][9] on the main php site. Each page allows for user comments, which I really like.
javascript: Found a decent tutorial [here][10] geared toward non-programmers. Found another more advanced one [here][11].
C#: The only decent one I could dig up was [this][12] one, but I am not a C# guy, so hopefully somone else has a better one.
What about you guys? I am totally off on some of there? Did I leave out your favorite language? I will take the best comments and modify the question with the suggestions.

I've defined my message class accordingly:

end
And everything seems to be working according to plan, but when trying to execute to show unread messages in my message view, I'm running into problems.
Their example: (I've changed underscores to hyphens due to formatting issues)
bob = User.find-by-name("bob")
bob.readings # => []
Post.find-unread-by(bob) # => [<Post 1>,<Post 2>,<Post 3>...]
Post.find-read-by(bob) # => []

But to no avail. I always seem to get stuck on the simple view issues after everything's set.

When the form loads, the text boxes are populated from a database. The user can change the populated values, and when they submit the form, I take the values posted to the server and conditionally save them (determined by some business logic). All but 1 of the text boxes work as intended.
The odd box out, upon postback, does not contain the updated value that the user typed into the box. When debugging the application, it is clear that **myTextBox.Text** reflects the old, pre-populated value, not the new, user-supplied value. Every other box properly shows their respective user-supplied values.
I did find a workaround. My solution was to basically extract the text box's value out of the Request.Form object: **Request.Form[myTextBox.UniqueID]**, which does contain the user-supplied value.
What could be going on, here? As I mentioned, the other text boxes receive the user-supplied values just fine, and this particular problematic text box doesn't have any logic associated to it -- it just takes the value and saves it. The maindifference between this text box and the others is that this is a multi-line box (for inputting notes), which I believe is rendered as an HTML "textarea" tag instead of an "input" tag in ASP.NET. | c# | asp.net | null | null | null | null | open | Form post doesn't contain textbox data [ASP.NET C#]

On one hand are those wordy documents which given to a programmer are likely to cause him/her missing a few things. I personally dread the word documents spec...I think its because of my reading style...I am always speed reading things which I think will cause me to miss out on key points.
On the other hand, I have seen this innovative specs written in Excel by one of our clients. The way he used to write the spec was kind of create a mock application in Excel and use some VBA to mock it. He would do things like on button click where should the form go or what action should it perform (in comments).
On data form, he would display a form in cells and on each data entry cell he would comment on what valid values are, what validation should it perform etc.
I think that using this technique, it was less likely to miss out on things that needed to be done. Also, it was much easier to unit test it for the developer. The tester too had a better understanding of the system as it 'performed' before actually being written.
Visio is another tool to do screen desing but I still think Excel has a better edge over it considering its VBA support and its functions.
Do you think this should become a more popular way of writing spec? I know it involves a bit of extra work on part of project manager(or whoever is writing the spec) but the payoff is huge...I myself could see a lot of productivity gain from using it. And if there are any better formats of specs that would actually help programmer.

"collapse" the "stacks" of dimension 1 down to a single 4 x 1 array:
_ _ _ _ _ _ _ _ _ _ _ _ _
|_ 1 _|_ 3 _|_ 2 _|_ 8 _|
This can then be summed, or have any operation performed.
I need to do this with an array of 'n' dimensions, which could feasibly be 20. Also, I need to be able to do this, caring about certain dimensions, and collapsing the rest. I am having an especially hard time with this because I cant visualize 20 dimensions :p . If anyone could help me set up some c/c++ code to do this, I would be very very grateful.

===
This may be a silly question, but I was curious how other people use the **this** keyword. I tend to use it in constructors but may also use it throughout the class in other methods. Some examples:
In Constructor:
public Light(Vector v)
{
this.dir = new Vector(v);
}
Elsewhere
public void SomeMethod()
{
Vector vec = new Vector();
double d = (vec * vec) - (this.radius * this.radius);
}

I'm designing the security side of our project, to allow us to have different versions of the program for different costs and also to allow Manager-type users to grant or deny access to parts of the program.
I'm using a simple Allow or Deny option for each 'Resource' or screen.
We're going to have a large number of resources, and the user will be able to set up many different groups to put users in to control access.
I've got two approaches to this in mind, and was curious which would be better for the SQL server
**Option A**
The presence of an entry in the table means access is allowed. This will not need a column in the database to store information. If no results are returned, then access is denied.
I think this will mean a smaller table, but would queries search the whole table to determine there is no match?
**Option B**
A bit column is included in the database that controls the Allow/Deny. This will mean there is always a result to be found, and makes for a larger table.

I'm using the FLVPlayback component to control the video inside of my program. While running memory checks using System.totalMemory I've noticed that whenever a video is loaded, it will eat up a chunk of memory and even when I remove all the event listeners from it(they are all weakly referenced), remove the component from its parent, stop the video and null the component instance, it still will not give that memory back.
This has been bothering me since I started working on this project because of the huge amount of video a user can potentially instantiate and load. Currently every video is loaded into a new FLVPlayback instance whenever it is required, but I have read that perhaps the best way to go about this problem is to simply have a global FLVPlayback instance and just reload the new video into the old instance, that way there would only be one FLVPlayback component in the application's memory.

The code is quite messy (partly because I have left out some spaghetti logic already) and I am trying to refactor it. Some more background info:
- As far as I know, the `oldSet` and `newSet` are actually backed by `ArrayList`
- Each set contains less than 100 items, most likely max out at 20
- This code is called frequently (measured in millions/day), although the sets seldom differ
My questions:
- If I convert `oldSet` and `newSet` into `HashMap<Foo>` (order is not of concern here), with the IDs as keys, would it made the code easier to read and easier to compare? How much of time & memory performance is loss on the conversion?
- Would iterating the two sets and perform the appropriate operation be more efficient and concise?

After I installed my required applications VS2005/2008, Sql Server editions client tools, Adobe CS3, and source control clients: **I am wondering what list of “must haves” developer tools that are out there these days?** I’m a big fan of Fiddler and LinqPad, but I am wondering what I am missing? | 4 |

Anyone have any ideas on how to fix this?

However, I have never come across a solution that searched for content within audio files. <br>
**For example:** Let us assume that I have about 200 podcasts downloaded to my PC in the form of mp3, wav and ogg files. They are all named generically say podcast1.mp3, podcast2.mp3, etc. So, it is not possible to know what the content is, without actually hearing them. Lets say that, I am interested in finding out, which the podcasts talk about 'game programming'. I want the results to be shown as:
* Podcast1.mp3 - 3 result(s) at time index(es) - 0:16:21, 0:43:45, 1:12:31
* Podcast21.ogg - 1 result(s) at time index(es) - 0:12:01
**So my questions:**
* How could one approach this problem?
* Are there are suitable algorithms developed to do something like this?
One idea the cropped up in my mind was that, one could use a 'speech-to-text' software to get transcripts along with time indexes for each of the audio files, then parse the transcript to get the output.
I was considering this as one of my hobby projects.
