While I knew that there are some documents named "Patterns and Practices" from Microsoft, I didn't know that there is a section for XML Performance. Sadly, I was scarcely satisfied by that document. The checklist is so insufficient, and some of them are missing the points (and some are even worse for performance). So here I put the "true" checklists to save misinformed .NET XML developers.

Enjoy mental workouts?
Use maths occasionally?
Like numerical brainteasers?
Revel in intellectual challenges?
Dabble in computer programming?

Answer "yes" to any of the above, and you've come to the right place!

What is a Puzzlet?

A mathematical problem which will almost always require the use of a simple computer program to solve.

You will need at least a rudimentary knowledge of maths to solve it, and occasionally more. You can use this skill to understand the problem, derive a formula to resolve it if necessary, and define the range within which the answer should fall.

At this stage, you will usually be unable to derive an exact answer, and will have to resort to a simple computer program to go further. You'll have to develop an algorithm, write the code, debug it, and get it to run.

Finally, you need to test your answer for accuracy and completeness. Many Puzzlets have several answers, and part of the challenge is to be sure you've found them all. That, then, is the complete Puzzlet experience!

One might think that computing the size of a directory would be a simple matter of adding up the sizes of all the files in it.

Oh if it were only that simple.

Windows File System Tunneling

Windows NT Contains File System Tunneling Capabilities:

When a name is removed from a directory (rename or delete), its short/long name pair and creation time are saved in a cache, keyed by the name that was removed. When a name is added to a directory (rename or create), the cache is searched to see if there is information to restore. The cache is effective per instance of a directory. If a directory is deleted, the cache for it is removed.

These paired operations can cause tunneling on "name".
- delete(name)/create(name)
- delete(name)/rename(source, name)
- rename(name, newname)/create(name)
- rename(name, newname)/rename(source, name)

The idea is to mimic the behavior MS-DOS programs expect when they use the safe save method. They copy the modified data to a temporary file, delete the original and rename the temporary to the original. This should seem to be the original file when complete. Windows performs tunneling on both FAT and NTFS file systems to ensure long/short file names are retained when 16-bit applications perform this safe save operation.
...
Tunneling cache time can be adjusted from the default time of 15 seconds, or if tunneling capabilities are undesirable, it can be disabled by adding a value in the Windows Registry.

A fenti cikk innen van:
Raymond Chen: The apocryphal history of file system tunnelling

O ezt irja meg:

As another example of the importance of tunneling, consider that file "File with long name.txt", whose short name is say "FILEWI~1.TXT". You load this file into a program that is not long-filename-aware and save it. It deletes the old "FILEWI~1.TXT" and creates a new one with the same name. Without tunnelling, the associated long name of the file would be lost. Instead of a friendly long name, the file name got corrupted into this thing with squiggly marks. Not good.

Justin Rogers: Understanding and Solving Internet Explorer Leak Patterns

In the past, memory leaks haven't posed huge problems for Web developers. Pages were kept relatively simple and navigation between different locations within a site was a great way to clean up any loose memory. If there was a leak, it was most likely small enough to go unnoticed.

New Web applications live up to higher standards. A page might run for hours without being navigated and retrieve updated information dynamically through Web services. Language features are pushed to the breaking point by combining complex event schemes, object-oriented JScript, and closures to produce entire applications. With these and other changes, certain memory leak patterns are becoming more prominent, especially those previously hidden by navigation.

The good news is that memory leak patterns can be easily spotted if you know what to look for. Most of the troublesome patterns you might face have known workarounds requiring only a small amount of extra work on your behalf. While some pages might still fall prey to small memory leaks, the most noticeable ones can be easily removed.

The following sections will discuss patterns of memory leaks and point out some common examples of each pattern.:

Circular References — When mutual references are counted between Internet Explorer's COM infrastructure and any scripting engine, objects can leak memory. This is the broadest pattern.

Closures — Closures are a specific form of circular reference that pose the largest pattern to existing Web application architectures. Closures are easy to spot because they rely on a specific language keyword and can be searched for generically. Eric Lippert, one of the developers of the scripting engines, has a great post on closures in general.

Cross-Page Leaks — Cross-page leaks are often very small leaks of internal book-keeping objects as you move from site to site. We'll examine the DOM Insertion Order issue, along with a workaround that shows how small changes to your code can prevent the creation of these book-keeping objects.

Pseudo-Leaks — These aren't really leaks, but can be extremely annoying if you don't understand where your memory is going. We'll examine the script element rewriting and how it appears to leak quite a bit of memory, when it is really performing as required.

In the interest of patterns and design I highly recommend Scott's short blog entry because it demonstrates a general purpose example of removing all closure-based leaks.

malicious web sites to spoof dialog boxes

Secunia Research has discovered a vulnerability in various browsers, which can be exploited by malicious web sites to spoof dialog boxes.

The problem is that JavaScript dialog boxes do not display or include their origin, which allows a new window to open e.g. a prompt dialog box, which appears to be from a trusted site.



The vulnerability has been confirmed in Mozilla 1.7.8, FireFox 1.04, and Camino 0.8.4. Prior versions may also be affected.

Solution:
Do not browse untrusted web sites while browsing trusted sites.

Connected Files

Az MSDN-ben ezt irjak a SHFileOperation Function alatt:

Connecting Files

With Microsoft Windows 2000 or later, it is possible to connect an HTML file with a folder that contains related files such as Graphics Interchange Format (GIF) images or style sheets. If file connection is enabled, when you move or copy the HTML file, the folder and all of its files are moved or copied as well. Conversely, if you move the folder with the related files, the HTML file is also moved.

The HTML file must have a .htm or .html extension. You create the connection to the related files by placing the folder that contains them into the same folder as the HTML file. The name of the folder that contains the connected files must be the same as the name of the HTML file followed by "_files" or ".files" (this is case sensitive; for example, ".Files" does not work). An example is given here.

1. Create a file named Test.htm in the C:\Files directory (C:\Files\Test.htm).
2. Create a new folder named Test.files in the C:\Files directory (C:\Files\Text.files).
3. Populate the folder with a few files. Any file placed in this folder is connected to Test.htm.
4. Move or copy the Test.htm file to the C:\Files2 directory.
5. Note that the Test.files directory is now found in the C:\Files2 directory as well.

File connection is enabled by default. It can be disabled by adding a REG_DWORD value, NoFileFolderConnection, to this registry key.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\NoFileFolderConnection

Setting NoFileFolderConnection to 1 disables file connection. If the value is set to zero or is missing, file connection is enabled.

Irtam nekik, hogy a peldajuk masodik pontjaban a "C:\Files\Text.files" reszt javitsak ki "C:\Files\Test.files"-re. Majd meglatjuk mi lesz.

CELEBRATE is a 30-month, € 5m Information Society Technology project supported by the European Commission. The main task is to create an innovative approach to teaching using eLearning technologies, based on a vision of what electronic content (resources, services and communication tools) may look like in the future.

A key aim of the project is to investigate how LOs can be handled by a new generation of Learning Content Management Systems (LCMS) from a variety of different vendors and to test the interoperability of these systems in a real-life demonstrator. It is intended that CELEBRATE will act as a catalyst for the European eLearning content industry (the entire value-chain including content owners, publishers, broadcasters, national school networks and technology platform vendors).

The project's evaluation activities particularly analyse the extent to which new, more flexible forms of content development and distribution (based on reusable LOs) impact upon the learning process and support a new pedagogy for eLearning in schools based on constructivist learning models. In particular, the project will assess how the use of LOs encourages the development of key ‘digital-age’ skills such as collaborative working, creativity, inter-disciplinary awareness, adaptiveness, intercultural communication and problem-solving.

Scott Mitchell: Enter and the Button Click Event

Of particular interest to ASP.NET developers, though, is that when creating an ASP.NET Web Form hitting Enter to submit the form seemingly sometimes causes the page's Button Web control's Click event to fire, and other times not. In this short article we'll see under what conditions a Button Web control's Click event might not fire when the user submits the page hitting Enter; furthermore, we'll look at a workaround.

A lenyeg:
The issue centers around the way that Internet Explorer posts back the form's controls when hitting enter in a form with only one single-line textbox. Specifically, Internet Explorer does not include the submit button's name/value pair in the post body. Since the submit button's name/value pair is not sent back, the ASP.NET engine cannot determine what induced the postback and therefore can't raise the appropriate Button Web control's Click event.
...
Without the information as to what button caused the postback, the ASP.NET engine cannot raise the corresponding button's Click event. Hence, if you have a Web Form with just one single-line text input (even if there are additional input fields, like CheckBoxLists, RadioButtonLists, DropDownLists, and so on), hitting enter in the text input will not cause the Button Web control's Click event to fire when using Internet Explorer - other browsers, such as FireFox, always send back the button's name/value pair, even if there is only one text input.

For additional information about Enter and form submission, as well as JavaScript techniques for disabling submissions via Enter and ensuring submissions via Enter (for older browsers), be sure to check out the following articles:

Greg Wilson: Top Ten Data Crunching Tips and Tricks

Every day, all over the world, programmers have to recycle legacy data, translate from one vendor's proprietary format into another's, check configuration files, and yank data out of web server logs. This kind of programming is usually called data crunching, and while it's not glamorous, knowing how to do it with the least amount of effort can make the difference between meeting a deadline and making another pot of coffee. These ten tips will take the headache out of crunching data.

1. Master the Classic Tools
2. Separate Input, Processing, and Output
3. Store Format Information in the Data Itself
4. Understand International Character Sets
5. Use Reluctant Matches and Graphical Tools
6. Nest and Subtract to Negate
7. Check for Holes
8. Use XSLT (with Caveats)
9. Use XPath Without Using XSLT
10. Check Your Work
