Like years past, I/O will feature over 90 in-depth sessions and the opportunity to meet and learn from other developers, including those from the more than 160 companies that will demo in the Developer Sandbox. For those unable to attend, video recordings of technical sessions will be available on YouTube following the conference.

From now until May, we’ll continue to list new speakers, new sessions, and new Sandbox participants on the Google I/O website. To keep up with the latest event info and details, follow us on Twitter.

You may have already noticed the newest additions to the dashboard, which we rolled out over the last week. Developers can now subscribe to their gadget’s directory comments with their favorite RSS reader, so it’s easy to stay current with your user’s concerns and desires. If you’re a developer with a lot of gadgets, we’ve added sorting options so you can keep gadgets ordered in the most useful way. Finally and for the first time, developers can easily submit and withdraw gadgets from the iGoogle directory, giving them even greater control over their presence on iGoogle.

We’re firm believers in the principle that empowering our developers is the best way to bring a great iGoogle experience to our users, so we’ll be listening to our developer community about the tools and data they need the most and the dashboard will continue to improve. In the meantime, you can play with the new version at: http://code.google.com/igoogle/dashboard/

These types of errors are much more common in languages like Arabic, where most of the letters are cursive. That means that the shapes of the letters change, based on the position of the letter in the word (initial, middle, final or isolated). Moreover, some Arabic letters are considered word breaks, meaning that the following letter must be in an “initial” shape. In other words, if the last letter of one word is a word break, the following word may not be separated with a space.

For example, the queries [وزارةالتعليم] and [وزارة التعليم] have an identical meaning (Ministry of Education) and they’re both written in a common form for Arabic documents. But they have different, albeit correct, formats — the first query is written as a single word, while the second is written as two. Google needs to understand that while they’re written differently, they mean the same thing and should yield the exact same search results. In this example, both queries were written correctly, just in different formats. But sometimes people just make errors — like repeating the same letter twice. For example, you might write [راائعة الجماال], repeating the letter “ا” twice in both query words. In this case the correct spelling should be [رائعة الجمال]. It’s important that Google search recognizes your query — despite spelling errors.

To address issues like this, we recently developed a search ranking improvement that targets certain Arabic queries. Our algorithm employs rules of Arabic spelling and grammar along with signals from historical search data to decide when to leave out spaces between words or when to remove unnecessarily repeated letters. Now, when you type a query leaving out spaces or repeating a letter, we’ll return better results based not only on what you typed, but also on what our algorithm understands is the “correct” query. For example, here’s what happens when you type [قصيدة راائعةالجماال] ([amazingly beautiful poem] in Arabic) with repeated letters and dropped spaces between words.

As you can see, the Google results contain the corrected query, the terms قصيدة رائعة الجمال, in bold.

For most people, this might seem like a small enhancement. But for us, it’s a big change. Our tests show we’ve improved search for 10% of Arabic language queries. Which, when you think about it, is a lot of people.

Working in the Method Scope with Static Variables in PHP 5 Classes
Despite their name, static properties can help in a wide variety of situations. If you’re not using them currently, and you regularly implement design patterns in your code, after reading this series you’ll wonder how you ever did without them.

PHP mistakes, misconceptions, bad practices and blatant no nos.
Go to any PHP help forum and you’ll be sure to see many bad practises, innocent misconceptions and blatant no nos. None of us are perfect and none of us started off writing great code. We have all had that moment where we looked back on a script that we wrote years ago and thought “what the hell was I thinking?”. But it is a process. You make mistakes, you learn from those mistakes and then you move on.

Practical Php Patterns: Composite
One of the most important structural patterns is the Composite one: its goal is managing a hierarchy of objects where both leaf objects and composition of other objects conform to a common interface. This hierarchy is usually constituted by part-whole relationships (often composition in the strict sense or aggregation), and it can be viewed as a tree.

Relationships between objects

Implementing Factory Methods in PHP 5
If you’ve ever developed desktop applications using mature object-oriented languages like C++ and Java, then it’s possible that you’ve found yourself saying a few funny phrases such as “I need to implement a factory method within this class,” or in the worst case: “this class needs to implement a factory method, but I don’t have a single clue about how to do that.” Surprisingly, you can implement these factory methods pretty quickly and easily in PHP 5.

A list for all seasons. Developers have the wp-hackers mailing list to discuss core and plugin code. Sometimes UI/UX stuff comes up and gets discussed there, but there is a whole universe of discussion around navigation labels, gradients, button styling, layouts, alignment, etc. that would be clutter on wp-hackers. Designers need a list to call their own, and now we have one. You can sign up for the wp-ui list to discuss ways to improve the interface or user experience of WordPress, and to discuss progress on design-related projects for the open source project, like the design challenges we’re going to have.

Design Challenges. We learned a lot from the icon design and header refresh contests, and we want to do these kind of open design challenges on a regular basis to give UI/UX designers who want to contribute to the WordPress open source project more opportunities to do so. If we could do one per month, that would be ideal, keeping the challenges relatively bite-sized to allow potential contributors an easy way to get involved at first. As each challenge is posted, people can use the list to bounce ideas off each other and work toward optimal solutions. I’m hoping the design challenges will evolve to be less contest and more collaboration. We’ll announce the first one before the end of January, so if you’re interested, please sign up for the list! (Hint: one will likely be a touch up to the Right Now dashboard module, to improve the information design, and there will be a couple of screen layout challenges coming up as well.)

Distributed Usability Testing. We started to try this out last year, and several dozen usability professionals volunteered to help get the program going, but a combination of scheduling and infrastructure issues combined to stall the progress. Having the “UI/UX contributor team” infrastructure in place, starting with the mailing list, will make it much easier to get this project going again.

Chit-chat. The weekly developer chats in IRC at #wordpress-dev have been very productive. We’ve created an IRC room at #wordpress-ui on irc.freenode.com so that we can have the same kind of “water cooler” for UI/UX contributors as for core code contributors. In addition to being a place where you can drop in and discuss core UI/UX (note: this room will not be a place to discuss the design of blog themes, it’s to discuss the design of the WordPress application itself), we’ll set up a weekly chat. Choosing a day and time for the chats will probably be the first discussion on the mailing list.

A blog of our own. Once again, taking a page from the code contributor infrastructure, we’ll set up a blog for UI/UX updates, announcements, progress reports, etc. This will be on WordPress.org in the nearish future, and will be announced to the mailing list when it is live.

So, if you want to become a contributor to core WordPress by using your design skills, join the wp-ui mailing list and get ready for a fun year!
