The result is [BowlSK][1]. However, as it has grown, and features have been added, it has gotten really difficult to keep things organized - mainly due to the fact that this is my first python project, and I didn't know anything about it until I started working.
What I have:
- Main Level contains:
- all .py files (didn't know how to make packages work)
- all .html templates for main level pages
- Subdirectories:
- separate folders for css, images, js, etc.
- folders that hold .html templates for subdirecty-type urls
Example:<br/>
http://www.bowlsk.com/ maps to HomePage (default package), template at "index.html"<br/>
http://www.bowlsk.com/games/view-series.html?series=7130 maps to ViewSeriesPage (again, default package), template at "games/view-series.html"
It's nasty. How do I restructure? I had 2 ideas:
- Main Folder containing: appdef, indexes, main.py?
- Subfolder for code. Does this have to be my first package?
- Subfolder for templates. Folder heirarchy would match package heirarchy
- Individual subfolders for css, images, js, etc.
- Main Folder containing appdef, indexes, main.py?
- Subfolder for code + templates. This way I have the handler class right next to the template, because in this stage, I'm adding lots of features, so modifications to one mean modifications to the other. Again, do I have to have this folder name be the first package name for my classes? I'd like the folder to be "src", but I don't want my classes to be "src.WhateverPage"
Is there a best practice? With Django 1.0 on the horizon, is there something I can do now to improve my ability to integrate with it when it becomes the official GAE templating engine? I would simply start trying these things, and seeing which seems better, but pyDev's refactoring support doesn't seem to handle package moves very well, so it will likely be a non-trivial task to get all of this working again.
Thanks.

> Visual Studio .NET macros

> To stop the macro from running, double-click the spinning cassette.

I have trouble clicking the balloon because my macro runs so quickly.
Is this controllable by some dialog box option?

* creating/writing items may be slower to enable quick lookup/reading
Ideally, the lookup of all items that are tagged with (at least) a set of n given tags should be done using a single SQL statement. Since the number of tags to search for as well as the number of tags on any item are unknown and may be high, using JOINs is impractical.

I have been given the oppurtunity to "dabble" in asp.net as well as other things such as Informatica. But everything has to fit in within the scope of my current duties. I would say that actual development work takes up about 70% of my time while the rest is dealing with internal customers and other business related issues.
I tinker with .net at home but that is a far cry from the environment at work which consists of a n-tier framework in.net 1.1 to WCF applications in 3.0.
My problem is making the transition from "legacy" to Enterprise .net application developemnt as well as modern development practices. Im not a dummy but the learning curve seems straight up with a limited amount of time that I have to work on it. Any advice would be appreciated.

Previous editions of this course were just 1 or 2 half-day sessions and covered topics including:
* new language features, e.g.
* header vs. implementation
* pointers and references
* memory management
* operator overloading
* templates
* the standard libraries, e.g.
* the C library headers
* basic iostreams
* basic STL
* using libraries (headers, linking)
* they'll be using Linux, so
* basic Linux console commands
* gcc and how to interpret its error messages
* Makefiles and autotools
* basic debugger commands
* any topic they ask about
During the course each person individually writes, compiles, runs, and debugs simple programs using the newly introduced features. Is this the best way to learn?
Which topics do you consider most crucial?
Which topics should be added or removed?

I would like to compress the HTML, CSS and Javascript that is delivered to the browser. The host has disabled mod_deflate and mod_gzip, so these options are out. I do have PHP 5 at my disposal, though, so I could use the gzip component of that.
I am currently placing the following in my .htaccess file:
> php_value output_handler ob_gzhandler
However, this only compresses the HTML and leaves out the CSS and JS.
Is there a reliable way of transparently compressing the output of the CSS and JS without having to change every page? I have searched Google and a number of solutions are presented, but I've yet to get one to work. If anyone could suggest a solution that they know to work, that would be very gratefully received.
Note, **Method 2** in **[The Definitive Post on Gzipping your CSS][1]** looks like a good solution, but I couldn't get it working. Has anyone else succeeded using this method?

I have a few sites on a shared host that is running Apache 2. I would like to compress the HTML, CSS and Javascript that is delivered to the browser. The host has disabled mod_deflate and mod_gzip, so these options are out. I do have PHP 5 at my disposal, though, so I could use the gzip component of that.
I am currently placing the following in my .htaccess file:
> php_value output_handler ob_gzhandler
However, this only compresses the HTML and leaves out the CSS and JS.
Is there a reliable way of transparently compressing the output of the CSS and JS without having to change every page? I have searched Google and a number of solutions are presented, but I've yet to get one to work. If anyone could suggest a solution that they know to work, that would be very gratefully received.
Note, **Method 2** in **[The Definitive Post on Gzipping your CSS][1]** looks like a good solution, but I couldn't get it working. Has anyone else succeeded using this method?

You create a socket, bind it to an interface and an IP address and get it to listen. I found a couple of web resources on that, and understood it fine. In particular, I found an article [Network programming under Unix systems][1] to be very informative.
What confuses me is the timing of data arriving on the socket.
How can you tell when packets arrive, and how big the packet is, do you have to do all the heavy lifting yourself? My basic assumption here is that packets can be of variable length, so once binary data starts appearing down the socket, how do you begin to construct packets from that?

$('#foo').data('oldhoverout',???);

PUT -> /ressource/ID/json

or
PUT -> /ressource/ID?format=json
So what is the best way to specify a format indicator?
If I specify the format with an query parameter and want to do a **PUT** how can I do this with curl?
curl -T test/data.json -d "format=json" http://localhost:5000/ressource/33
does not work.
curl -T test/data.json http://localhost:5000/update?format=json
works, but I would rather let curl build the query parameters instead of adding them by myself.

/* Inside TestController, route to this action is 'test-route' */
public ActionResult TestAction(String param)
{
/* ... */
}
The URL that leads to this action looks like this:
TestController.mvc/TestAction/param
In the view this action redirects to I would like to have a form that can submit to this action different values for 'param'. I.e. the action should be:
TestController.mvc/TestAction
I have tried a few things, but if I recall correctly they all use a common method in the framework that prefills parameters where possible. Here is what I have tried:
<form method="get" action="<%=Url.Action("TestAction")%>">
and
<form method="get" action="<%=Url.RouteUrl("test-route")%>">
and
<% using (Html.Form("TestController", "TestAction", FormMethod.Get)) { %>
However, because param is already included in the URL for the page all of the rendered forms for these calls have an 'action' of TestController.mvc/TestAction/param.
Can someone please let me know what I'm missing :-) | c# | asp.net-mvc | forms | routing | null | null | open | ASP.NET MVC Preview 4 - Stop Url.RouteUrl() etc. using existing parameters

This application uses the Win32 CryptoAPI to generate a TripleDES session key for encrypting/decrypting data. We're using the [exponent of one trick][1] to export the session key out as a blob, which allows the blob to be stored somewhere in a decrypted format.
The question is how can we use this in our .NET application (C#). The framework encapsulates/wraps much of what the CryptoAPI is doing. Part of the problem is the CryptAPI states that the TripleDES algorithm for the [Microsoft Enhanced Cryptographic Provider][2] is 168 bits (3 keys of 56 bits). However, the .NET framework states their keys are 192 bits (3 keys of 64 bits). Apparently, the 3 extra bytes in the .NET framework is for parity?
Anyway, we need to read the key portion out of the blob and somehow be able to use that in our .NET application. Currently we are not getting the expected results when attempting to use the key in .NET. The decryption is failing miserably. Any help would be greatly appreciated.

PBEWithMD5AndDES or PBEWithSHA1AndDESede which provides encryption upto 56 bit and 80 bit (http://en.wikipedia.org/wiki/Desede).
I referred other guys posts but those are mainly using RSA and in my understanding RSA is generally suitable for encrypting the communication data (with private-public key pair). My need is different, I just want to store the data and retrieve it back by decrypting it. Therefore I don't need any private-public key pairs.
Please let me know if you have any idea about this.
Thanks in advance.
