Two week ago, I have the pleasure to take part in HTML5Fest Israel and give the keynote. It was a great event that the Israeli office of the W3C organize. If you wish to read some of the main points check out this blog post. It was a short talk because I thought I had 30min but in the end of the day… It was shorter.
Nevertheless, I had great time having interesting conversations with lead developers in the crowds for the rest of the day. I can’t wait for next year event…
Last night, I gave this talk to Google Developer Group Tallinn about the new APIs that we have today in HTML5 and CSS3. It was (another) great hangout where you can ‘touch’ people that are quite far from your location and speak with them about mutual interest.
Some of the topics that I covered during the talk where: Continue reading
Last week, I’ve went to live person HQ to give a talk in ILTechTalks on HTML5 and how you can use some of its new APIs in order to build you next web app. Today, web apps like: gmail, maps, google docs etc’ are consider to be modern web apps. They are rich, interactive applications that users spend long hours with them. There are few features that distinguish modern (or great) web apps from sites: Continue reading
Today I’ve spoke on GDL-IL (=Google Developer Live Israel) with Ron Reiter on his work at Any.Do and how he leverage backbone.js to create this useful chrome extension. The main points we covered during our talk:
Enjoy and feel free to join us every week on WED 14:00 Israel time at https://developers.google.com/live/
Here is a short webcast that shows how to build “IndexedDB in a jQueryMobile app”. If you thought about building a modern web application with offline capabilities, it will be a good 101 session for you. For the full code you can read “How to use indexedDB” and here is a live demo of this mobile web app. It seems that with the JavaScript shim that I’m using this is a nice solution for developers that wish to target both Android and iOS as it should work in both Chrome for android and mobile safari. Moreover, soon when IE10 will be in the ‘wild’ web, indexedDB API will be available in Chrome, FF and IE, nice ahh?
Btw, one of the reader of the blog point me to another open source IndexedDB API wrapper library – From browsing it, it’s looking good!
In the last Java Posse Roundup (=the best unconference you can attend) we had many very interesting meetings. In this one hour conversation we were talking about modern great web apps and what does it means to different developers. Some of the topics we spoke about where around new JavaScript MV* frameworks (ember, backbone, spine, angular etc’). What we used to do 35 years ago (main frames days!) and what is similar (or not) today. Thanks to @joelneely for correcting me with the title by making a great point on replacing the word ‘modern’ with ‘great’. Some of the topics that were discussed:
Since we had no-snow and free time, we did few ‘rolling’ hackathons in the afternoons. You can browse the coding projects on GitHub JavaPosseRoundup. Checkout, some cool Scala, Android, HTML5 apps that are there. Lastly, I also gave a talk about this topic before the conference at a Google developer meetup. Here are the “Modern Web Apps slides from my talk that contain more good information about the subject.
In the past few months, I’ve saw many developers that use local storage for ‘big data’ on the client side. Local storage is a powerful API that let developer save key-value data on the browser. However, it’s got some limitation like: synchronize operation that make it less efficient when it’s heavily used. Moreover, it should replace simple cases (e.g. saving the user state) and not in scenarios where you wish to save lots of data and then have the ability to ‘slide and dice’ it base on your needs with effiency. For that, we used to have WebSQL (which as you know is deprecated from 2010) and the new cool kid in town – IndexedDB. Here I will try to give you a short example that will run nicly both on IE10, Firefox (that match the spec) and Chrome (which need to tune a bit the setVersion update to call onupgrade). IE10 will support IndexedDB as well – so it’s great news to web developers in terms of ‘wild’ support for this important API in browsers. I wish we will see soon Safari (specially, on the mobile) match Chrome for android and give us the ability to leverage indexedDB both on Android and iOS.
Ok, as Linus said: “talking is cheap, show me some code”… Let’s go over the example code. In this example we will save todos to keep things simple. Classic, no? In the end of the post, I will also give two other examples of a ‘todo app’ the use indexedDB, WebSQL and jQueryMobile.
A short discussion with the team that built the first SubDroid that sink in Sedot Yam!
Some good topics on Android, Hackathons and design aspects for successful GeekCon project.
As always, if you have 20-25min on WED at 14:00 Israel time… mark your calendars and join us live on GDL-IL!
Yesterday I had the pleasure to do another webcast with O’rielly. This time the subject was “Modern web apps & HTML5 New APIs“. The webcast covered new (and old) techniques for building modern web apps and how to utilize the latest HTML5 APIs to create a new class of web apps that will delight and amaze your users. Some of the main topics were:

Here is some of the feedback I got on Google+
Be strong.
Since the first days of Chrome extensions it was clear that they are very powerful way to extend your browser and make it do stuff you care about. However, while it was good, we knew that it can get better… and this is why we have in dev channel the ‘Event Pages’. Let’s start by defining what are those pages:
It seems that with Event Pages our Chrome will be able to reduce the memory foot print that is used by some idle extensions. It’s an important evolution from the state of background pages that run all the time. An event page only runs when it is handling events. Once an event page becomes idle, it is unloaded, freeing memory until the next time it’s needed. To help event pages support some important use cases, we’re also have new APIs.
