Whatsapp : The most popular messenger

WhatsApp is the most popular messaging application worldwide and that has enormous potential as a long-term business. The recent elimination of the annual fee is an interesting business movement that is directly related to a change in the ecosystem of WhatsApp, which also jump right into the business world, you want to create its own social environment, an ecosystem of more than 1,000 million user.
Two years ago Facebook purchased WhatsApp 19,000 million dollars, an amount which, in its time, was considered crazy. With the inclusion of the annual fee of about a dollar to reapply 2,300 million users would be required to capitalize on service purchase, unthinkable and would not achieve. For this the company has dispensed with an annual fee not lead anywhere, and he did run a risk that many users will end up moving to other messaging applications like free or WeChat Telegram.

Along with the announcement of the abolition of the quota, a strategic change was made to approach the business world. However, the idea had long since WhatsApp plans, and the idea is that every company has invoked the application to facilitate contact between companies with their customers, avoiding the annoying call centers. This business service will be available later this year, and is only an intermediate step towards the future of WhatsApp: become a community, a platform for social content.

The messaging app concept has hardly evolved in WhatsApp or Facebook Messenger, but in its Asian rivals like Line or WeChat. These platforms are not just a messaging app, is itself a portal where they can access their own application store, exclusive games and services and make an appointment with your doctor or see the traffic, with certain surcharges to users.

Android tricks

The autonomy of the mobile terminals is a real headache for users. There are many ways that seek to achieve increasing, such as the use of specific applications, but there are some simple tips that if followed can save power without excessive complications

Lollipop brought Android 5.0, finally, a long-awaited feature, a way "do not disturb" series, but removed something all users used, complete silence. That is, not even the vibration is eliminated. To bring it back there are two applications. A fuller, called SoundHUD, which replaces the panel Lollipop volume and presents one classic extended (with volume control alarm, music, notification ...) and True Silent Mode, which is nothing more than a widget that allows you to set from the home screen mode volume we want, and the silence between them is no vibration.

Stop background apps

With indefinitely to run in the background, we can install wonders as Fliktu, TapPath or Clipper. The first, as we saw, we can replace the Android share menu and sharing links with different gestures and the clipboard contents. With the second set functions as the numbers of taps we make on the links, and the third, monitoring the clipboard contents, not porder nothing.

How to block contacts on your iPhone 6

The easiest way to block a contact on an iPhone passes than directly from the native function that incorporates mobile. All iPhone have a section that allows you to block a contact from the phonebook, and the procedure to block a contact in particular is as simple as following these steps:
First, we enter the phone application, which is represented by an icon of green with a picture of a phone inside.
Then we select in the bottom of the tab "Contacts" screen, and click on the contact you want to block. In the event that the number you want to block is not on our agenda, since this same section click on the icon "+" you will see in the upper right of the screen, enter the number block and assign it to a new contact.
Once we open the contact card, we seek an option with the name "Block this contact" and click on it.
Finally, the phone will warn us with a popup that by taking this action, we will do is block calls from a contact, also including your messages and contacts through the application FaceTime. Click on the option "Block contact" and the lock is immediately applied to this contact.

Evothings DYI Beacon app

You remember the movie Minority Report, where marquees ads acknowledged that passed near them to show ads to you? Well that exists and is called iBeacon, sensors are used to position an object indoors. This tutorial is for advanced level and you need several special devices that are not found at home, but that if you've created a modern tool that thanks to mobile application can detect you and send you to the mobile screen personalized information.

Raspberry pi turned into autonomous remote-controlled car

A developer named Wang Sheng wanted to join the progress that exist in the autonomous car segment but from a point of view more fun: instead of developing a project to convert a regular car into an autonomous car, wanted to see if I could do something similar with a remote control car through the Raspberry Pi.Said and done: its unique small-scale vehicle was able to follow a road, in addition to detect, understand and respond to the stop signs and traffic lights, and even avoid collisions. It is a limited version of what the Google autonomous car, and although there are obviously many differences-and not only in size-, the idea is fantastic.Many technology in very little spaceTo achieve Wang hit the official camera of the Raspberry Pi this mini PC, and all this was compounded by an ultrasonic sensor. From there two programs that were running on the Raspberry Pi allowed to manage the information received and transmitted by the low resolution video (320 x 240) camera captured another computer via WiFi.

The $5 computer : Raspberry pi zero

Model B Raspberry Pi tiny computer 2, which went on sale last February, costs about 32 euros; those of the first version are a bit cheaper: you can get the A + for about 20 euros. But now the foundation for educational purposes have been overcome: its latest development, dubbed Zero plate, worth just over four and a half euros (five US dollars).
Its creators announced the launch in late November and as promotion premiere, even given away with the magazine they publish because "the only thing better than a five-dollar computer is free one."
The objective of minimizing the cost is to reach a wider audience. He explains to Teknautas Eben Upton, one of the initiators of the Raspberry Foundation: "We want the price is not a barrier for young people to start in computing." They have done, no doubt, but how they have managed to remove 20 euros for the bill?
The first was to consider what were the minimum requirements for your product could be considered a "real computer". From them, they thought an initial outline of his physical appearance and began designing prototypes (two generations).
"We gave a final turn to reorganize some connectors and add an analog TV output. Then we started production, "describes Upton, computer and technical director of the communications company Broadcom.
"The biggest challenge has been getting high quality components at a reasonable cost," he continues. To apply the low cost philosophy have turned on the one hand, the economy of scale. In your opinion, it is simple: "If you buy a larger volume, you get better prices."
On the other hand, they played with design details. "We removed everything that was not essential," continues Upton. They have dispensed with some pieces related to power control via USB, analog audio output and connections for monitor and camera.

The aim was to reduce the price, even at the cost of other attributes. While Raspberry Pi 2 B has optimize performance oriented design, Zero is slower. It has the same processor (Broadcom BCM2835) and the same RAM (512 MB) than its predecessors, the Raspberry Pi 1.
Based on the technical specifications and an initial BOM, Sony has manufactured the devices in Wales (UK). The technology company has bought semiconductors, connectors, PCB or PCB (of printed circuit board) and other components from different suppliers. It has also proposed some changes accepted by the foundation provided that the alternative was justified.
Although Broadcom employee admits it's been a challenge, he says they have it easier than someone starting from scratch. "We can make cheaper devices because we have great engineers and good relations with suppliers and distributors," he says.
One of the professionals involved in the project is Mike Stimson, part of the team only since early this year. Stimson explains that took three months to go from the first production schemes. Also he worked at Broadcom, where did the BCM283x chips that carry Raspberry Pi.

"I've never participated in a design of low budget," admits Stimson. The hardest thing, in his opinion, has been to maintain the small size of the PCB despite using low cost technology, but is satisfied with the result: "Working for a charity I think is very positive and always foundation projects are a challenge, "he says.
For Upton, the real prize (while incentive) is the response of the people. "The letters we receive from parents showing how their children learn computer technology using Raspberry Pi" he confesses, "is what keeps us ahead in the worst of times".
