In corporate finance and investment banking, risk analysis is a crucial job. To assess risk, analysts review research, monitor economic and social conditions, stay informed of regulations, and create models for the investment climate. In short, the inputs into an analysis make for a highly complex and dynamic calculation, one that requires enormous computing power. The vast number of calculations and the way the math is structured typically allows for high degrees of parallelization across many separate processes. To satisfy such a need, grid computing employs any number of machines working together to execute a set of parallelized tasks — which is perfect for risk analysis. By using a networked group of computers that work together as a virtual supercomputer, you can assemble and use vast computer grids for specific time periods and purposes, paying, only for what you use. Also, by splitting tasks over multiple machines, processing time is significantly reduced to increase efficiency and minimize wasted resources.

The Azure Industry Experiences team has recently authored two documents to help those involved in banking scenarios. We show how to implement a risk assessment solution that takes advantage of cloud grid computing technologies.

The first document is a short overview for technical decision makers, especially those considering a burst-to-cloud scenario. The second is a solution guide. It is aimed at solution architects, lead developers and others who want a deeper technical illumination of the strategy and technology.

Today, we are happy to introduce support for the Web Authentication specification in Microsoft Edge, enabling better, more secure user experiences and a passwordless experience on the web.

With Web Authentication, Microsoft Edge users can sign in with their face, fingerprint, PIN, or portable FIDO2 devices, leveraging strong public-key credentials instead of passwords.

Staying secure on the web is more important than ever. We trust web sites to process credit card numbers, save addresses and personal information, and even to handle sensitive records like medical information. All this data is protected by an ancient security model—the password. But passwords are difficult to remember, and are fundamentally insecure—often re-used, and vulnerable to phishing and cracking.

For these reasons, Microsoft has been leading the charge towards a world without passwords, with innovations like Windows Hello biometrics and pioneering work with the FIDO Alliance to create an open standard for passwordless authentication – Web Authentication.

We started this journey in 2016, when we shipped the industry’s first preview implementation of the Web Authentication API in Microsoft Edge. Since then, we have been updating our implementation to as we worked with other vendors and the FIDO alliance to develop the standard. In March, the FIDO Alliance announced that the Web Authentication APIs have reached Candidate Recommendation (CR) status in the W3C, a major milestone for the maturity and interoperability of the specification.

Beginning with build 17723, Microsoft Edge supports the CR version of Web Authentication. Our implementation provides the most complete support for Web Authentication to date, with support for a wider variety of authenticators than other browsers.

Windows Hello allows users to authenticate without a password on any Windows 10 device, using biometrics—face and fingerprint recognition—or a PIN number to sign in to web sites. With Windows Hello face recognition, users can log in to sites that support Web Authentication in seconds, with just a glance.

Users can also use external FIDO2 security keys to authenticate with a removable device and your biometrics or PIN. For websites that are not ready to move to a completely passwordless model, backwards compatibility with FIDO U2F devices can provide a strong second factor in addition to a password.

We’re working with industry partners on lighting up the first passwordless experiences around the web. At RSA 2018, we shared a sneak peak of how these APIs could be used to approve a payment on the web with your face. Passwordless authentication experiences like this are the foundation of a world without passwords.

We’re excited to get implementation into the hands of more developers to see what you build. To get started with Web Authentication in Microsoft Edge, check out more information on our implementation in the Web Authentication dev guide, or install Windows Insider Preview build 17723 or higher to try it out for yourself!

Visual Studio Code, or VS Code, is an open source code editor that also includes tools for building and debugging an application. With the Python extension enabled, vscode becomes a great working environment for any Python developer. This article shows you which extensions are useful, and how to configure VS Code to get the most out of it.

If you don’t have it installed, check out our previous article, Using Visual Studio Code on Fedora:

Using Visual Studio Code on Fedora

Install the VS Code Python extension

First, to make VS Code Python friendly, install the Python extension from the marketplace.

Once the Python extension installed, you can now configure the Python extension.

VS Code manages its configuration inside JSON files. Two files are used:

• One for the global settings that applies to all projects
• One for project specific settings

Press Ctrl+, (comma) to open the global settings.

Setup the Python Path

You can configure VS Code to automatically select the best Python interpreter for each of your projects. To do this, configure the python.pythonPath key in the global settings.

// Place your settings in this file to overwrite default and user settings. { "python.pythonPath":"${workspaceRoot}/.venv/bin/python", }

This sets VS Code to use the Python interpreter located in the project root directory under the .venv virtual environment directory.

Use environment variables

By default, VS Code uses environment variables defined in the project root directory in a .env file. This is useful to set environment variables like:

PYTHONWARNINGS="once"

That setting ensures that warnings are displayed when your program is running.

To change this default, set the python.envFile configuration key as follows:

"python.envFile": "${workspaceFolder}/.env",

Code Linting

The Python extension also supports different code linters (pep8, flake8, pylint). To enable your favorite linter, or the one used by the project you’re working on, you need to set a few configuration items.

By default pylint is enabled. But for this example, configure flake8:

"python.linting.pylintEnabled": false, "python.linting.flake8Path": "${workspaceRoot}/.venv/bin/flake8", "python.linting.flake8Enabled": true, "python.linting.flake8Args": ["--max-line-length=90"],

After enabling the linter, your code is underlined to show where it doesn’t meet criteria enforced by the linter. Note that for this example to work, you need to install flake8 in the virtual environment of the project.

Code Formatting

VS Code also lets you configure automatic code formatting. The extension currently supports autopep8, black and yapf. Here’s how to configure black.

"python.formatting.provider": "black", "python.formatting.blackPath": "${workspaceRoot}/.venv/bin/black" "python.formatting.blackArgs": ["--line-length=90"], "editor.formatOnSave": true,

If you don’t want the editor to format your file on save,  set the option to false and use Ctrl+Shift+I to format the current document. Note that for this example to work, you need to install black in the virtual environment of the project.

Running Tasks

Another great feature of VS Code is that it can run tasks. These tasks are also defined in a JSON file saved in the project root directory.

Run a development flask server

In this example, you’ll create a task to run a Flask development server. Create a new Build using the basic template that can run an external command:

Edit the tasks.json file as follows to create a new task that runs the Flask development server:

{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "label": "Run Debug Server", "type": "shell", "command": "${workspaceRoot}/.venv/bin/flask run -h 0.0.0.0 -p 5000", "group": { "kind": "build", "isDefault": true } } ] }

The Flask development server uses an environment variable to get the entrypoint of the application. Use the .env file to declare these variables. For example:

FLASK_APP=wsgi.py FLASK_DEBUG=True

Now you can execute the task using Ctrl+Shift+B.

Unit tests

VS Code also has the unit test runners pytest, unittest, and nosetest integrated out of the box. After you enable a test runner, VS Code discovers the unit tests and letsyou to run them individually, by test suite, or simply all the tests.

For example, to enable pytest:

"python.unitTest.pyTestEnabled": true, "python.unitTest.pyTestPath": "${workspaceRoot}/.venv/bin/pytest",

Note that for this example to work, you need to install pytest in the virtual environment of the project.

As global economies move ever closer to a digital future, companies and organizations in every industry vertical are grappling with how to further integrate and deploy technology throughout their business and operations. While Enterprise IT largely led the way, the advantages and lessons learned are now starting to be applied across the board. While the national unemployment rate stands at 4.1%, the overall unemployment rate for tech professionals hit 1.9% in April and the future for open source jobs looks particularly bright. I work in the open source networking space and the innovations and opportunities I’m witnessing are transforming the way the world communicates.

Once a slower moving industry, the networking ecosystem of today — made up of network operators, vendors, systems integrators, and developers — is now embracing open source software and is shifting significantly towards virtualization and software defined networks running on commodity hardware. In fact, nearly 70% of global mobile subscribers are represented by network operator members of LF Networking, an initiative working to harmonize projects that makes up the open networking stack and adjacent technologies.  

Demand for Skills

Developers and sysadmins working in this space are embracing cloud native and DevOps approaches and methods to develop new use cases and tackle the most pressing industry challenges. Focus areas like containers and edge computing are red hot and the demand for developers and sysadmins who can integrate, collaborate, and innovate in this space is exploding.

Open source and Linux makes this all possible, and per the recently published 2018 Open Source Jobs Report, fully 80% of hiring managers are looking for people with Linux skills while 46% are looking to recruit in the networking area and a roughly equal equal percentage cite “Networking” as a technology most affecting their hiring decisions.

Developers are the most sought-after position, with 72% of hiring managers looking for them, followed by DevOps skills (59%), engineers (57%) and sysadmins (49%). The report also measures the incredible growth in demand for containers skills which matches what we’re seeing in the networking space with the creation of cloud native virtual functions (CNFs) and the proliferation of Continuous Integration / Continuous Deployment approaches such as the XCI initiative in the OPNFV.

Get Started

The good news for job seekers in that there are plenty of onramps into open source including the free Introduction to Linux course. Multiple certifications are mandatory for the top jobs so I encourage you to explore the range of training opportunities out there. Specific to networking, check out these new training courses in the OPNFV and ONAP projects, as well as this introduction to open source networking technologies.
