Two talks in one day…

That’s what I did yesterday for Google Developer Group (GDG) Athens, Greece. It was a great opportunity to talk about the new cool aspects of google cloud platform (Yep, checkout things like: NodeJS on Compute Engine, App engine new support for technologies, Monte Carlo Simulations with App Script, Cloud storage, Big Query and many more). We talked for the first 25min on the new aspects of developing mobile web sites (and/or mobile web apps). In one word – go check out yeoman.io. Of course, there are many more aspects that are in the slides, so feel free to browse them and please let me know if I’ve missed something important that you are using in your mobile web project.

Raspberry Pi And Google Coder #socool

The Web is awesome and this week I had the pleasure to play with a new ‘face’ of the web platform. It’s built for Raspberry Pi and you can take it as far as your imagination will let you.

Coder

Coder is a very cool project that aim to be a simple way to make web stuff on Raspberry Pi. Short and sweet. It is also an experiment for Raspberry Pi that give you a free piece of software that turns a Raspberry Pi into a simple, personal web server and web-based development environment. Basically, all that you need, for crafting HTML5, CSS, and JavaScript.  Plus, it’s an open-source project so you could fork it and learn from the source on http://googlecreativelab.github.io/coder/ Continue reading →

Mobile Web App – Real Life Example

App scriptThis week in Google Developers Live Israel, we showed a live example of a mobile web app that is built in two ways. One we used jQueryMobile as our UI framework and for cases where we need to support IE we used bootstrap. All the code can be found on github. The nice aspect in this real demo is that we used google sheets are our ‘server side’ and since its got a cool way to publish their content to the web as RSS, ATOM, XML, JSON feeds we could work with them from the web/mobile apps. The three main elements we used are: Continue reading →

Install NodeJS On Compute Engine

NodeJS

In the past, I’ve showed how to run a NodeJS application in Compute Engine. It’s a good case where you wish to test ideas with App Script but when you move them to ‘production’ – NodeJS is the answer. After the Google Developer Live show we had at the end of August, I got few questions on how to install NodeJS inside Compute Engine instance.

Here are the (easy) steps I did before the show in order to save us time: Continue reading →

Debug NodeJS Like A Pro

NodeJS Debugging with Chrome

NodeJS Debugging with Chrome

Anyone who is building an application find out that, what is starting as ‘small project’, becoming very quickly bigger and bigger monster. You can use console.log on small projects but as they are growing you will need better tools. In the arena of “JavaScript on the server” there weren’t many tools to debug your code effectively. However, with the power of open-source projects like: Node, Blink and others there are few powerful ways to debug you code like a pro.

First, for the one that are a bit confuse about NodeJS. Well, it’s not a “JavaScript web server” but an environment to run JavaScript on the server. It is using V8 engine so the performances are very compelling. After using NodeJS inside Compute engine I got few questions about the debugging options. In the past, developers needed to use console.log and similar ‘printing’ commands in order to understand what is going under the hood of their script. But as we mention, when you get out of the area of 100 lines script and your application contain different modules and many more lines of code. You need a debugger (and hopefully other tools like profiler) in your hands. Luckily, we can use Chrome (=Blink) dev tools for your NodeJS applications.
Here are the main steps and the ways to leverage your new ‘hammer’. Continue reading →

Yahoo Finance API With NodeJS

nodejs logoIn the past I’ve wrote this post on the different options you can use with Yahoo Finance API. It is time (4 years later!) to a followup post on how to gain more data but this time with NodeJS.
The first idea was to be able to gain information by using different parameters and downloading csv files from Yahoo finance. Something like this GET request will do the magic:

http://finance.yahoo.com/d/quotes.csv?s=NFLX&f=snd1l1yr and from there you can work with the data.

However, there are cases, where you wish to have information that is not part of this set of arguments. Here are two quick examples for such cases: Continue reading →

WebRTC Updates

webrtc logoIn this week show on Google Developers live Israel we hosted Sam Dutton in order to hear what’s new in the land of WebRTC. What? Well, Web Real-Time Communication (WebRTC) is a collection of standards, protocols, and JavaScript APIs that enables peer-to-peer audio, video, and data sharing between browsers. We covered (with demos) the three primary APIs:

  • MediaStream: acquisition of audio and video streams
  • RTCPeerConnection: communication of audio and video data
  • RTCDataChannel: communication of arbitrary application data

It was a fun 20min talk with some very impressive demos. Here are few demos that show the power of getUserMedia API: Continue reading →

Chromebook For Developers And Hackers

If you are a Linux hacker and/or a developer with a new Chromebook, Chromebox, Pixel or an old laptop with ChromeOS… You might want to have the ability to have a dual-boot option that will let you enjoy the power of your ChromeOS but on the same time be able to boot your laptop with Linux and enjoy C, C++, Java and the fun technologies. It might be hard on other platforms to ‘hack’ them, but since the chromium project is open-source, I guess, they wanted to be hackable by design (e.g. you have a keyboard shortcuts in Pixel that let you enter this mode). Here are the few steps you need to follow in order to enjoy hacking ChromeOS. Continue reading →

Google Cloud Platform – App Engine and Beyond

Screen Shot 2013-07-11 at 2.43.33 PMFew minutes ago we finish a great event in Campus TLV. We had the pleasure to have Dr Peter Magnusson (Director of Engineering for App Engine at Google) and Greg DeMichillie (Director Product Management, Cloud Platform at Google). For the ones, that do not know what is GAE: Google App Engine is a complete development stack that uses familiar technologies to build and host applications on the same infrastructure used at Google. It is used by some of the world most successful and demanding global applications such as SnapChat and Khan Academy. We also cover Google Compute Engine which allows everyone to Run large-scale computing workloads on Linux virtual machines hosted on Google’s infrastructure. I’ve spoke about Google Cloud Endpoint and you can watch the full talk on my project’s site.

Ido talking in the campus on cloud

This is the raw recording form the event of all three talks. I hope to have an edited version soon…
