After the keynote, I gave another talk on HTML5 and big data (with google cloud services). Overall, it was a great experience and the organizer did a great job. I hope to be able to make it again next year…
In this Google Developer Live episode I covered some of the new elements you wish to pay attention when you are starting to develop your Google Chrome Extension. If you don’t know what is an extension and why it’s great way to improve Chrome, try this true 101 tutorial first. As you (might) know, there is a new version for the manifest file that include few improvements. The first basic change is to add this simple declaration:
manifest_version: 2
This is a mandatory and if you have a current extension in the Chrome web store I suggest you update it to include it. The second bold change in the manifest file is the ability to make it more secure. For this we have to define what is our extension’s Contact Security Policy. In the demo case that I’ve showed, it will look like that: Continue reading
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/
It is a busy week (and we are only on TUE). First, we had the opportunity to host four founders from around the world (Sweden, Moscow and Israel) on GDL-IL. It was in a special episode about: Sartups, VCs, Angles and how to improve your pitch. I had the pleasure to host Eze Vidra, Head of Google Campus London who gave important feedback after each pitch. The structure of the show was like that: each founder got 3 minutes to pitch his startup and then we gave them feedback and asked more questions in order to understand the strengths better. I liked the fact that each founder choose a different way to pass his message. It was very interesting to hear the progress and learn about the key accomplishments that each of them made. I will write a more detailed summary of this conversation but for now you can enjoy it over here:
Second, last night, fresh from the oven a new podcast in hebrew on HTML5 and CSS3 New & Cool Stuff saw life. I had the honor to be a guest (again) on reversim.com and talk about new web technologies that I’m passion about. If you are a developer that wish to hear quality content in hebrew on subjects that relate to your profesional life. Give it a try, today they have more then 150 episodes that cover A LOT of topics. You can download the mp3 file from here.
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.
