Full Stack Journey 029: The Ballerina Programming Language With Anjana Fernando

Today's Full Stack Journey podcast dances with Ballerina, a cloud-native programming language introduced by WSO2. My guest is Anjana Fernando, who has been involved in Ballerina since its inception. We discuss use cases and compare Ballerina to languages such as Java and Golang.

The tradeoff is that users’ credentials are then centrally stored and managed, typically protected by a single master password to unlock a password manager data store. With the rising popularity of password manager use it is safe to assume that adversarial activity will target the growing user base of these password managers. Table 1, below, outlines the number of individual users and business entities for each of the password managers we examine in this paper.

Imagine that you’re about to give a presentation in front of your entire organization. If you have ever been anxious in a situation where the stakes are high, you’ve probably received well-meaning advice: Calm down. Take deep breaths. Think positively, and you will nail this. —Barry Brownstein

“Photographs furnish evidence,” wrote Susan Sontag in On Photography. “A photograph passes for incontrovertible proof that a given thing happened.” Sontag went on to write of how photographs can misrepresent situations. But do they even have to show real objects? —Ben Sixsmith

Scammers tend to be skilled at finding the most vulnerable individuals and turning them into victims. Case in point: Researchers at Proofpoint have been tracking campaigns that prey on those looking for work. The payoff Continue reading

Connecting RasPBX via SIP Trunk

The previous tutorial has covered RasPBX installation on Raspberry Pi 3 board. At the end of the tutorial we have tested local calls between chan_sip extensions 1010 and 1020 that are registered to RasPBX. This time we will go further and connect RasPBX with another FreePBX VOIP system via PJSIP trunk. The FreePBX is running on VirtualBox and it is in version 14 with Asterisk 13. As the last step of the tutorial, we will test VOIP calls  between RasPBX with FreePBX that are interconnected by PJSIP trunk.

As we have mentioned, a complete RasPBX and Zoiper softphones installation and configuration is covered in a previous tutorial (except the SIP trunk).  Also, the tutorial does not cover installation of FreePBX on VirtualBox VM. So far, our inventory contains RasPBX and FreePBX with the following components.

RasPBX - Asterisk on Raspberry PI board:
- Asterisk 13.22.0
- FreeBPX 14.0.3.13
- Zoiper softphone on Ubuntu 18.0.4, IP 172.17.100.2/16, ext. 1010
- Zoiper softphone on Android 5.1, IP 172.17.100.5/16, ext. 1020

FreePBX - Installed  on VirtualBox VM
- Asterisk 13.19.1
- FreeBPX 14.0.3.13

Deploying Workers with GitHub Actions + Serverless

Deploying Workers with GitHub Actions + Serverless

If you weren’t aware, Cloudflare Workers, our serverless programming platform, allows you to deploy code onto our 165 data centers around the world.

Want to automatically deploy Workers directly from a GitHub repository? Now you can with our official GitHub Action. This Action is an extension of our existing integration with the Serverless Framework. It runs in a containerized GitHub environment and automatically deploys your Worker to Cloudflare. We chose to utilize the Serverless Framework within our GitHub Action to raise awareness of their awesome work and to enable even more serverless applications to be built with Cloudflare Workers. This Action can be used to deploy individual Worker scripts as well; the Serverless Framework is being used in the background as the deployment mechanism.

Before going into the details, we’ll quickly go over what GitHub Actions are.

GitHub Actions

GitHub Actions allow you to trigger commands in reaction to GitHub events. These commands run in containers and can receive environment variables. Actions could trigger build, test, or deployment commands across a variety of providers. They can also be linked and run sequentially (i.e. ‘if the build passes, deploy the app’). Similar to many CI/CD tools, these commands run Continue reading

The Open Compute Project is quickly gaining ground

Eight years ago, Facebook launched the Open Compute Project (OCP), an open-source hardware initiative to design the most energy-efficient server gear for massive, hyperscale data centers. The promise was flexibility of hardware and software and designs for greater power efficiency.Very quickly, Intel, Rackspace, Goldman Sachs and Sun Microsystems' co-founder Andy Bechtolsheim joined with Facebook to launch the OCP project, with Microsoft joining in 2014.The project has hummed along quietly with no sales figures until now, thanks to supply chain market research specialists IHS Markit. It surveyed both Facebook, Microsoft, and Rackspace, as founding partners, and looked at sales to customers beyond those three.To read this article in full, please click here
