me: What is the long term future of javafx.ext.swing.* classes in JavaFX’s
technological roadmap? Are new Node-based ui classes in-the-works to supercede this?
Joshua Marinacci: We plan to keep the swing classes but they will only be in the desktop profile. New gui classes based on nodes are in the works. These new gui components will be [...]

I was having a play with custom renderers in Java Swing, and comparing them with the effort required in .NET. I find that in this case, the Swing approaches the problem at a higher level of abstraction (less effort), at the expense of a lot of new objects being created, while .NET goes for a [...]

Python developers are probably already familiar with List Comprehensions, and lambda expressions. The interesting twist with LINQ is these expressions are translated into SQL and executed on the RDBMS instead of being done on the client side. There was a pretty clever Python project that achieved this in Python through dissassembly of python bytecodes, but [...]

I’ve been listening to MIX’08 talking about new uses for mobile phones and I came across this piece of news:

Jomo Fisher demonstrates how tail call works in CLR using mutual recursion in F# as an example:

Now, I don’t really know what this means. Does it mean that MS is going to guarantee some kind of backwards compatibility and offer official stable/supported releases?

Yang Xing reports:
Developer [sic] should avoid encoding Space into “+” or double encoded into “%2b”. It is recommended that when encode [sic] URL use “System.Uri.EscapeDataString”, when decode URL use “HttpUtility.UrlDecode”
Sigh. There are days when one just wishes one’s back in Python-land.
Contrast with the following Python-equivalent:

>>> urllib.quote(‘255 m’)
‘255%20m’
>>> urllib.quote_plus(‘255 m’)
‘255+m’
>>> urllib.unquote(‘255%20m’)
‘255 m’
>>> urllib.unquote_plus(‘255%20m’)
‘255 m’
>>> urllib.unquote_plus(‘255+m’)
‘255 m’

Zef writes in Ajax Reality Check that

Does anybody realize where we came from and that these “web 2.0 technologies” aren’t great at all, but just the best we could do — in the browser?

However, I assert that desktop apps do have something to learn from the browser¹, and it’s not ajax.

Can AJAX be used to strengthen REST-style programming? Yes! Here are some common scenarios where AJAX is better than standard HTML.
User authentication
Display authentication dialog on the URL where access is attempted, instead of redirecting to a logon screen, and then redirecting back.
Dialogs
Present dialogs using DHTML instead of popping up windows. URLs should be permanent if [...]

Alexander Jung has a post outlining how ASP.net 2.0 data binding is implemented using code generation. A more detailed look at ASP.net 2.0 databinding internals is available at DotNetDan. Looking at the generated code, it surprised me that the Bind() method doesn’t even appear in the final generated code. Makes one wish that the ASP.net [...]

There’s a live discussion over at sogrady’s blog whether RIA’s will ever gain a foothold on the web. Stephen points out that HTML had been adequate for most online tasks people wish to do today – webmail, search, banking, and that AJAX is useful in filling in the gaps.
On the other hand, David (who works [...]

Anyone exposed to ASP.net syntax will come to realize
ASP.net is not XML
Here is a page example that contains typical tags (sorry about the space between < and tag names, :

<%@ Page Language=”VB” %>

    <%– Server Side Comment –%>
    <script runat=”server”
      language=”VB”>

       Function MyFunction() As String

Issuing an Insert command on an ObjectDataSource typically requires two database calls:
1) INSERT INTO mytable ….
2) SELECT @@IDENTITY
If you are prototyping against Access databases, one problem that becomes quickly apparent is that OleDb providers do not support multiple SQL statements. So you can’t do set the following commandtext in a DataTableAdapter method:
INSERT INTO mytable ….;
SELECT [...]

You have to read the story behind this quote about developing software on top of the .Net 3.0 framework:

“I want to develop for the .NET 3.0 framework”
I don’t think you could find a smaller market segment if you tried. Perhaps writing software for Bulgarian asparagus farmers?

TIP:
If you bind controls to data using BindingSource, make sure you call
bindingSource1.EndEdit()
before you serialize to your data store. It’ll save a few red-faces.

Once in a while, it is gratifying to see how Microsoft’s embrace and extend comes back and bite them in the a***. Take Microsoft’s Internet Explorer, back when MS was defending their Windows OS turf against Netscape’s Browser OS. Microsoft, in their infinite wisdom, decided to extend the browser to include ActiveX applets. Now there is already a large base of ActiveX components on the Windows platform, so naturally, adding ActiveX components to web browsers would help entrench Microsoft’s dominance on the client side right?

As history has turned out, the answer is a resounding NO.

When dealing with Strongly Typed datasets on the ASP.net GridView 2.0, I found myself writing one too many lines of code like this:

<asp:TemplateField HeaderText="Category">
<ItemTemplate>
<%# DataBinder.Eval(
((System.Data.DataRowView) Container.DataItem).Row,
"CategoryRow.CategoryName") %>
</ItemTemplate>
<asp:TemplateField>

Solution?

<asp:TemplateField HeaderText="Category">
<ItemTemplate>
<%# EvalEx(Container.DataItem, "CategoryRow.CategoryName") %>
</ItemTemplate>
<asp:TemplateField>

protected object EvalEx(object DataItem, string [...]
