Rob Glazebroook post a new articleshoing how CSS can help in SEO. He writes:

«We all know the overt benefits of using CSS by now – being able to centrally locate all of our presentation, the ability to replicate design changes instantly over an entire website, and so on. But not everyone is sold on such details. These days, a lot of people are more interested in SEO (Search Engine Optimization, or making your pages look good in search engines) than anything else. So what happens if you have a client or an employer whose mantra is more along the lines of, “SEO at any cost, CSS be damned”?

Well, I have some good news for you! Using CSS (and its trusty sidekick, XHTML) is actually very beneficial to your SEO standings. Below, I’ve outlined four different ways that using CSS can help you improve your search engine optimization. Some of them happen automatically, while others require you make decisions.»

Andrew Tetlaw post a new article about event delegation in JavaScript. He write:

«If you’re into adding a little JavaScript interactivity to your web pages you may have heard of JavaScript event delegation and thought it was one of those convoluted design patterns only hardcore JavaScript programmers worry about. The truth is, if you already know how to add JavaScript event handlers, it’s a snap to implement.

JavaScript events are the bedrock of all interactivity on web pages (I mean serious interactivity, not those dinky CSS drop-down menus). In traditional event handling you add or remove event handlers from each element as needed. However, event handlers can potentially cause of memory leaks and performance degradation — the more you have, the greater the risk. JavaScript event delegation is a simple technique by which you add a single event handler to a parent element in order to avoid having to add event handlers to multiple child elements»

Kathleen Dollard post an article in which she gave some advices to C# developers who needs to write some codeee in VB.NET. Here'd small excerpt from this article:

«I just had an e-mail exchange with someone looking for a VB lead in Colorado Springs. I think they are going to have trouble filling it with an existing VB expert, and it occurred to me that someone who had led a successful VB 6 -> C# project could fit the bill, if they knew some key things about VB. I told the recruiter I thought the right person with a C# background and the right (respectful) attitude could be a good fit with two weeks work. But in the back of my mind I’m thinking “what resource could she possibly access during those two weeks.”

I am sold on the concept of polyglot programming and think every C# coder should know enough VB to do Office, late binding, and XML work in VB. That’s not what I’m talking about. Those should be wrappers and really the quality of code doesn’t matter.

I’m talking about embracing the language enough to lead a team, and I'm assuming there's honesty on all sides so the C# coder is admitting they are growing and learning. The framework is so core to what we do that it doesn't make sense to demand one language or another. But it does make sense if your crossing over in either direction to embrace the elegance of the language you’re going to work in. »

Bipin Joshi posst the second part of article about using LINQ in ASP.NET. He writes;»

«In the Part 1 of this series I discussed the basic operations of LINQ to SQL. By default when you use LINQ to SQL queries as shown earlier, they internally use SQL statements i.e. INSERT, UPDATE, DELETE and SELECT. In many real world applications you use stored procedures. Luckily, LINQ to SQL has a way to call stored procedures from your application. It involves bit of a work as compared to almost automated way discussed earlier. In this article I will explain how stored procedures can be consumed using LINQ to SQL.»

«Hot on the heels of the recent ASP.NET AJAX roadmap, Bertrand and team have released a limited preview of the new AJAX functionality coming in ASP.NET 4.0.

To see how the new functionality stacks up, I decided to recreate my recent jTemplates example, using only ASP.NET AJAX and its new templating features. Eventually, I settled on using the DataView class, which offers more advanced, repeater-like functionality.»

Kilian Valkhof writes about creating your own lightboxes. He writes the following:

«A lightbox is a way of showing an image, a movie or an entire web page as an overlay on a website. It is often used in gallery style websites and for portfolio’s. This article will look into the basics of building your own lightbox for images.

Part 2, published next week, will look into some of the cooler stuff:

• Loading in pages instead of images

• Adding a loading animation

• Adding a nice close button

• Using cool different animations

• Send some text along with an image and display it next to it

• Display multiple lightboxes on top of each other

• Combining all the above »

Stoyan Stefanov post an article in which he tells about non-blocking loading JavaScript source files. He writes:

«Let’s first take a look at what the problem is with the script downloads. The thing is that before fully downloading and parsing a script, the browser can’t tell what’s in it. It may contain document.write() calls which modify the DOM tree or it may even contain location.href and send the user to a whole new page. If that happens, any components downloaded from the previous page may never be needed. In order to avoid potentially useless downloads, browsers first download, parse and execute each script before moving on with the queue of other components waiting to be downloaded. As a result, any script on your page blocks the download process and that has a negative impact on your page loading speed.

Here’s how the timeline looks like when downloading a slow JavaScript file (exaggerated to take 1 second). The script download (the third row in the image) blocks the two-by-two parallel downloads of the images that follow after the script:»

Scott Mitchell post the next article from the series about ASP.NET Membership. This time he shows how to apply user- and role-based authorization rules to methods and classes. He writes:

«Several of the earlier installments in this article series examined how to apply authorization rules in order to prohibit particular users, roles, or classes of users from accessing particular resources. For instance, Part 2 how to define URL-based authorization rules in web.config for roles. With just a bit of XML markup, it is possible to block particular users or roles from visiting certain web pages. Just installments also looked at using the LoginView control, which displays different markup based on whether the user is authenticated or not (and can also be used to display different markup based on the currently logged in user's role). There are also programmatic techniques you can use to determine the identity of the currently logged on user and what roles she belongs to.

The URL-based authorization, LoginView control, and programmatic techniques can be used in tandem to ensure that a user does not visit a page or perform some operation if she is not authorized. But what if you forget to implement one of these safeguards? For example, imagine that you have a web page that includes a button that, when clicked, perform some task that is only intended for administrators. You could put this button in a LoginView control or you could use programmatic techniques to ensure that only users in the appropriate role (say, Admin) saw the button. But what if sometime later you, or another developer, removed this check by accident? The net result would be that any user visiting the page could perform the administrator-only operation! »
