Despite the popularity of such services as messagers, skype, voip, emails, etc. good old-fashioned phone calls remain one of the best and the most popular form of communication for billions of people all over the world. Full Stack Python had prepared a tutorial for you about how to make and receive phone calls from any application with just a few lines of Python code plus a web application programming interface

In the tutorial, example calls will say a snippet of text and put all incoming callers into a recorded conference call.

Requirements:

  • Python 2 or 3
  • pip and virtualenv to handle application dependencies
  • A free Twilio account to use their phone calling web API
  • Twilio's Python helper library, version 5.7.0, which is available on PyPI

Twilio is a web application programming interface (API) that software developers can use to add communications such as phone calling, messaging, video and two-factor authentication into their Python applications.

Created app will use the Twilio Python helper library to create an HTTP POST request to Twilio's API.

Ethereum Scaling Solution Raiden to Launch Last Testnet

As noted by the developers, after implementing the new solution, the Ethereum network will be able to provide more than a million transactions per second

On Thursday, July 19, at the Dappcon developer conference in Berlin, the last test network of Raiden for the Ethereum blockchain was launched, CoinDesk reports.

The release includes a minimal implementation of the scaling solution, which will allow the transfer of Ethereum tokens outside of the main blockchain. This is the last test phase before the introduction of technology into the core network of Ethereum.

It's the first step towards going to the mainnet. We really want people to really test this so we have a user interface, we have an API and we've created an open Github for everything they could find, so if we go hopefully bug-free on the mainnet.
 

Lefteris Karapetsas

Core Developer, Raiden

According to him, the new release represents an early implementation for the core network and contains a new rewritten code of smart contracts and payment channels that can be restored in case of unintended closure.

Also, Karapetsas urged developers to join the test network to help detect possible bugs, adding that a bounty program will be launched to encourage this activity.

The release date for the main network has not yet been assigned, but the developers intend to follow this earlier promise and launch Raiden this summer.

Karapetsas also promised to publish regular updates and code optimizations after the full release, adding that Raiden will complement other Ethereum scaling solutions that are currently being developed.

Raiden is essentially the payment channel network for ethereum, it's supposed to help us scale token transfers. The long term goal would be to have people use Raiden from a mobile device and be able to make off-chain token transfers just from their phone. That would be the long term vision, it would probably work in combination with various scaling solutions, sharding, plasma, a sort of hybrid.

Raiden is developing from the 2015 and is written mostly on Python. The project is much like the Lightning Network. As noted by the developers, after implementing the new solution, the Ethereum network will be able to provide more than a million transactions per second.
