Arduino and Processing Workshop

What is Arduino?

     Arduino, an Italian name meaning "strong friend", is a popular "open-source electronics prototyping platform based around a micro-controller. It accepts inputs, such as signals from sensors (light, temperature, moisture, etc.) or data from the Internet or wireless devices, and sends output signals to devices, such as LED, motors, speakers, MIDI sequencers, computers, and so on."

     In simpler terms: It is a ready-to-use creative platform, designed to provide interactivity between humans, smartphones, PCs, sensors and the physical world. It is especially a boon for creative people who don't have a technical background and want to translate their wildest techno-ideas to reality in a snap.

What Arduino can do?

     Arduino,is made to be hooked up to sensors which feed it physical information. These can be as simple as pressing a button, or as complex as using ultrasound to detect distance, or in the above example, monitoring the current flowing between two nails in soil: when the soil gets dry, the current drops and the Arduino carries out instructions: In this case it talks to a Zigbee internet-connected radio and posts a Twitter message, but you could just as easily have it talk to a robot which would water the plant for you.

Who can Attend?

     The workshop is especially meant for those who are enthusiastic to get started with creative projects in new technology and people those who do not have prior experience in electronics, interfacing and all hack talk. This Workshop help you to have a general understanding of instructional programming languages, but this shouldn't be a problem for starts as you will pick it up as we go along. Besides, we are super-friendly and will assist participants to demystify code.

By 2020, you could have an exascale speed-of-light optical computer on your desk

Optalysys, a UK technology company, says it’s on-target to demonstrate a novel optical computer, which performs calculations at the speed of light, in January 2015. If all goes to plan, Optalysys says its tech — which is really unlike anything you’ve ever heard of before — can put an exascale supercomputer on your desk by 2020.

When we talk about optical computing, we’re actually referring to a fairly large number of different and competing technologies. At its most basic, optical computing refers to computing that uses light instead of electricity. When we’ve previously written about optical computing, we’re usually referring to chips and computers that have replaced their internal wiring with optical waveguides, and some kind of optical transistor that is controlled by photons instead of electrons. There are also optoelectronic devices, which use a mix of the two (usually optical interconnects and electronic transistors).

In the case of Optalysys, optical computing is something else entirely. At this point, because the Optalysys tech is rather complex, you should probably watch the video embedded below — not only will it probably do a better job than me at explaining it, but it’s also narrated by the adorable Heinz Wolff. If you can’t watch the video, read on and I’ll try my best.

It goes something like this. You start with a low-power laser. This laser is then directed through a massive liquid crystal grid. This grid works in much the same way as a liquid crystal display. By applying electricity to each “pixel,” the laser light passing through it is affected. Complex calculations would turn hundreds or thousands of these pixels on or off. After the laser has passed through this grid, the beam is picked up by a receiver. By analyzing the beam’s diffraction and Fourier optics, matrix multiplication and Fourier transforms can be combined to perform complex maths. You can also have multiple pixel grids in sequence or parallel, significantly boosting the complexity and parallelism of the optical computer. There’s a little more technical info on the Optalysys website, but not much.

Moving away from the technical nitty-gritty, Optalysys’s optical computer is exciting for two main reasons: It consumes very little power, and there’s essentially no limit on how parallel you can make it. There’s no direct analogy to transistor-based logic, but you could almost think of every liquid-crystal pixel as a tiny processing core (or at least a tiny transistor). In a normal computer chip, while there is some parallelism, most things happen very sequentially, with each core (and each transistor) working mostly in serial. In an Optalysis optical computer, the laser beam hits every single pixel at the same time — it essentially performs hundreds or thousands (or millions?) of small computations in parallel, at the speed of light.

New Nexus 9 leak points to 64-bit Nvidia Tegra K1, 4GB of RAM, and 2560×1600 screen

Google has been setting the tone ofAndroid devices with its Nexus program since 2010 when the HTC-built Nexus One was announced. Now over four years later, HTC is rumored to be coming back to the Nexus program in true style, building its first tablet in years. Leaked documents and specs for the Nexus 9 (codename Volantis) have been appearing for weeks, and the newest cache of information offers up a few more tantalizing details. If you’re in the market for a tablet, this might be the one to wait for.

Nexus phones and tablets usually include a few hardware compromises to come in at a competitive price point. The Nexus 9 (or maybe Nexus 8, depending on Google’s final naming decision) will be bringing some serious specs to the table, including the debut of Nvidia’s 64-bit Tegra K1 ARM processor paired with 4GB of RAM. That would be a jump from current high-end Android devices, which top out at 3GB.

The choice of processor is consistent across the leaks, so it’s probably one of the more solid aspects. That’s a good thing too — even the 32-bit K1 is crazy-fast. Nvidia previously said the 64-bit K1 based on its custom Denver CPU core was due out late in 2014, which also lines up with an alleged release date for the Nexus 9. This chip will only have two cores, as opposed to the 32-bit K1 with its four Cortex-A15 ARM cores. However, the move to the ARMv8 instruction set and Nvidia’s highly optimized architecture could mean the dual-core 64-bit chip vastly outperforms the quad-core variant. The new chip will have the same Kepler desktop-like GPU as the current 32-bit K1, making it great for gaming.

The screen leaks for the Nexus 9 are a little inconsistent, but the newest round of rumors points to a 2560×1600 resolution display at 8.9-inches. That would put it at 339 pixels per inch, significantly higher than most other tablets, but still behind phones with 1080p screens. Some past leaks pointed to a square screen ratio like an iPad, but even then the rumored resolutions didn’t match up. 2560×1600 would likely make the Nexus 9 a widescreen device — it’s the same resolution as the nearly two-year-old Nexus 10.

The budget approach to the two Asus-built Nexus 7s certainly attracted price-conscious consumers, but they didn’t serve as great showcases for Android. The original Nexus 7 had that nasty storage controller issue that caused it to grind to a halt after a few months of use, and the 2013 N7 had a variety of touchscreen issues. These weren’t bad devices, but they didn’t have the kind of performance or reliability you’d expect from a premium device. With Google’s big Android L release fast approaching, premium is where it needs to be, and the Nexus 9 is rumored to start north of $300.

Android L is without a doubt the most significant update the platform has seen since at least 4.0 back in 2011. Google is rethinking the design guidelines, the colors, the lock screen, and even the notification shade (which has been sacrosanct for years). All the leaks say the Nexus 9 is going to be a launch device for Android L, so now is not the time to skimp on hardware. Google needs to make this one splashy, even if that means a slightly higher price. If the hardware leaks so far are accurate, this is going to be one fastest tablets ever built. That would be a great way to kick off a new era for Android.

Local notifications iOS example

Notifications: Notifications are similar to reminders or alerts. iOS supports this feature. there are two type of notifications.

• Push notifications
• Local notifications

Push Notifications: iOS supports push notifications(APNS) from iOS3.0. iPhone requires internet connectivity to work this.  As notifications will be coming from remote server.
Local Notifications: iOS supports Local notifications from iOS4.0. As the name says, these notifications are local to the iPhone and it doesn’t require any internet  connection.

Lets see more on local notifications iOS example and how can we implement these local notifications in iPhone.
We will create a simple app which fires a local notification after 10 secs of a button click. Lets a create a button and
add below code on the button click event.

How it looks on the Device:

To send the local notification, we need to set the fire date of when to fire/send the notification to the application.
we need to set time, message to the notification. there are some optional properties to set for the notification.

first we need to create the UILocalNotification instance by using alloc and init as given above. Once allocation is success, we need to
set the fireDate, message and timezone properties.

Properties need to set for the local Notifications:
fireDate: When exactly you want fire/send the notification. There are many ways to set this. Here I am using very simple
way to set alert to send 10 sec from current time.
AlertBody: When sending the notification, we need to set some meaningful message related the remainder like ‘Its time to wake up’ ;-).
timeZone: This field is optional, but its good practice to set the timezone as there are different timezones.

After setting the properties, we need to link or add this local notification to the application. If we miss this step,
application don’t know about the notification details. So we need to add this to the application.

Now we are fine with creating local notification and sending to the application. When the application receives this,
how to display or inform. there are two scenarios

Application running on Background:This is the default option for the most of the cases. if you specify the message,
that message will be shown as a alert banner at the top of the home screen.
Application running on Foreground: If the application is in the foreground or currently running, most of the local notifications
ignored by default. If we want to show some alert message, didReceiveLocalNotification delegate method we need to add in appDelegate.m file

Technicolor-PostWorks completes 'Hundred-Foot Journey'

NEW YORK — Mark Gethin, the creative director of color at MPC USA, recently spent several weeks in New York City, providing final color for the new DreamWorks feature The Hundred-Foot Journey. The film — produced by Steven Spielberg and Oprah Winfrey — is set in the south of France, where the proprietress (Helen Mirren) of a celebrated French restaurant sees competition from the Kadam family, who open a new restaurant directly across the street. The film also stars Om Puri, Manish Dayal, and Charlotte Le Bon.

Gethin, who is based out of MPC in Santa Monica, specializes in commercial work, and it was his working relationship with the film’s director of photography Linus Sandgren that brought him into this project. Gethin says he’s been working with Sandgren on spots for at least 10 years, and the two also collaborated on the 2012 feature Promised Land.

For The Hundred-Foot Journey, Gethin spent three weeks in New York City, working out of Technicolor-PostWorks New York, where he performed the DI using a Baselight system. The feature, says Gethin, was shot in France and India, and was captured primarily on 35mm anamorphic film, with additional material shot using an Arri Alexa.  

“Linus and director [Lasse Hallström] wanted to give it a mood that it was a sweet and happy film, but they didn’t want to do a generic happy and sweet look,” he recalls. “A lot of it was about the mood and how far we could take it. It was really about the atmosphere of the movie. The color, especially the stuff that was shot in India, looks fantastic anyway, so it was really about getting the right mood for it.”

Film work, says Gethin, is much different than the commercial work he typically sees, where he can spent hours on just :30 of material. “You don’t have that time,” he states of feature work. For The Hundred-Foot Journey, Gethin spent the first two weeks going through the film and making changes to get it “in a good place,” he explains.
