When restructuring our online courses we decided to make the video content that was previously part of Ansible online course available with Standard ipSpace.net Subscription.
If you haven’t enrolled into our automation online course (which always included the extra bits) you’ll find the following additional content in our Ansible for Networking Engineers webinar:
Is the inclusion of specialized matrix engines in general-purpose processors truly motivated and merited, or is the silicon better invested in other parts?
What’s Really Motivating the Matrix Engine Movement in HPC? was written by Nicole Hemsoth at The Next Platform.
This is guest a post by Preetam Jinka, Senior Infrastructure Engineer at ShiftLeft. Originally published here.
ShiftLeft NextGen Static Analysis (NG SAST) is a software-as-a-service static analysis solution that allows developers to scan every pull request for security issues. Earlier this year we released Secrets, Security Insights, and a v4 API. Secrets and Security Insights are two new types of results we extract from code analysis, and the V4 API is a brand new RESTful JSON API with an OpenAPI/Swagger specification that you can use to access all of your results. Read more about these features in our announcement post.
NG SAST was initially designed only for vulnerabilities. In order to implement Secrets and Security Insights, we either had to retrofit these new result types into our existing implementation or significantly refactor our back-end to support their unique characteristics. Even though it would take longer and be more difficult to implement, we decided to do the latter. We rewrote almost all of the storage used for storing code analysis results while maintaining backwards compatibility and without any outages. The analogy is that it’s like changing the engine on an airplane in flight without the passengers noticing.
We could’ve saved Continue reading
About a month ago we talked about how we planned to make Docker Desktop more first class as part of our Pro and Team subscriptions. Today we are pleased to announce that with the latest release of Docker Desktop we are launching support for Docker Desktop for Pro and Team users. This means that customers on Pro plans or team members on Team plans will be able to get support outside of the community support in our Github repository, this will include installation support, issues in running Desktop and of course the existing support for Docker Hub.
Along with this, we have our first Pro feature available in Docker Desktop! For Pro and Team users who have scanning enabled in Docker Hub, you will be able to see your scan results directly in the Docker Dashboard.
This is the first step in releasing unique features for Pro and Team users on Docker Desktop.
Along with this we are pleased to announce that in Docker Desktop 2.5 we have the GA release of the docker scan CLI powered by Snyk! To find out more about scanning images locally have a read of Marina’s blog post.

Getting hit from both sides: Executives from Google, Twitter, and Facebook faced criticism from all sides when testifying in the U.S. Senate recently, the Washington Post reports. Democratic senators told the companies they should do a better job with moderating their sites for fake news and conspiracy theories, while Republicans called on the companies to take a more hands-off role with political speech.
Your money, or else: A wave of ransomware attacks have hit nearly two dozen hospitals and healthcare organizations in recent weeks, Wired.com reports. Even after those attacks, the U.S. Cybersecurity and Infrastructure Security Agency, Federal Bureau of Investigation, and Department of Health and Human Services warned that more may be coming, with an “increased and imminent cybercrime threat” to hospitals and healthcare providers.
Safer Zooming: Videoconferencing provider Zoom has added encryption to free accounts, although the new protections come with a catch, TechCrunch says. With end-to-end encryption enabled for every user joining the call, some other features won’t be available. Users on encrypted calls won’t be able to use features like cloud recording and live transcription, and they won’t be able to chat one on one. Also, the encryption feature will only work with the Continue reading
Private Automation Hub is now available as part of Red Hat Ansible Automation Platform release 1.2, providing an easier way for our customers to manage their Ansible content. Whether they produce private content, access trusted and supported content from Red Hat or obtain content from third party or other community sources, an internally controlled capability is essential to support the continued growth of automation. As automation becomes critical to managing IT activities, so too becomes the need to have a focal point where collaboration can be encouraged, content shared and trust reinforced.
Private Automation Hub is a self-hosted Ansible content management system. Organizations can host private hubs on their own infrastructure and manage it themselves. Similar to how Red Hat Satellite enables Red Hat Enterprise Linux customers to manage operating system content, private Automation Hub enables automation teams to manage Ansible automation content. Private Automation Hub allows curation and distribution of Ansible content as close as possible to Ansible Automation Platform clusters. Private Automation Hub is included in the Red Hat Ansible Automation Platform subscription.
Ansible content can be broken up into three main categories:
On a good day, there are different people around. The way we converse with them and communicate is completely different. There are ways we talk to those we are older than us, those younger than we are, those we respect, those who lose our respect with time, and it goes on and on. This article aims to talk about the elements of effective communication.
Elements of Effective Communication includes the following:
Whenever we converse with people and we say something, we are simply speaking knowledge we already possess. But whenever we listen to others, most times we get the chance to absorb and learn something new.
Speaking and listening work together. As you communicate with other people, these roles are completely fluid. The speaker might not be talking the entire time. One of these important elements of communication is for each of us as speakers to listen with attention.
These elements of Simplicity and Clarity are also two beans in a pod. But these aspects cannot be used synonymously. What one means by clarity is that you shouldn’t have any doubt about what you’re talking about. Speaking with confidence Continue reading
Helios: hyperscale indexing for the cloud & edge, Potharaju et al., PVLDB’20
Last time out we looked at the motivations for a new reference blueprint for large-scale data processing, as embodied by Helios. Today we’re going to dive into the details of Helios itself. As a reminder:
Helios is a distributed, highly-scalable system used at Microsoft for flexible ingestion, indexing, and aggregation of large streams of real-time data that is designed to plug into relationals engines. The system collects close to a quadrillion events indexing approximately 16 trillion search keys per day from hundreds of thousands of machines across tens of data centres around the world.
As an ingestion and indexing system, Helios separates ingestion and indexing and introduces a novel bottoms-up index construction algorithm. It exposes tables and secondary indices for use by relational query engines through standard access path selection mechanisms during query optimisation. As a reference blueprint, Helios’ main feature is the ability to move computation to the edge.
Helios is designed to ingest, index, and aggregate large streams of real-time data (tens of petabytes a day). For example, the log data generated by Azure Cosmos. It supports key use cases such as finding Continue reading
This short article documents how I run Isso, the commenting system used by this blog, inside a Docker container on NixOS, a Linux distribution built on top of Nix. Nix is a declarative package manager for Linux and other Unix systems.
While NixOS 20.09 includes a derivation for Isso, it is unfortunately broken and relies on Python 2. As I am also using a fork of Isso, I have built my own derivation, heavily inspired by the one in master:1
issoPackage = with pkgs.python3Packages; buildPythonPackage rec { pname = "isso"; version = "custom"; src = pkgs.fetchFromGitHub { # Use my fork owner = "vincentbernat"; repo = pname; rev = "vbe/master"; sha256 = "0vkkvjcvcjcdzdj73qig32hqgjly8n3ln2djzmhshc04i6g9z07j"; }; propagatedBuildInputs = [ itsdangerous jinja2 misaka html5lib werkzeug bleach flask-caching ]; buildInputs = [ cffi ]; checkInputs = [ nose ]; checkPhase = '' ${python.interpreter} setup.py nosetests ''; };
I want to run Isso through Gunicorn. To this effect, I build an
environment combining Isso and Gunicorn. Then, I can invoke the latter
with "${issoEnv}/bin/gunicorn".
issoEnv = pkgs.python3.buildEnv.override { extraLibs = [ issoPackage pkgs.python3Packages. Continue reading
As some of you know – Im a big believer that we all learn differently. You may read something the first time and immediately grasp the topic whereas I may read it and miss the point entirely. For me, decorators have been one of those things that I felt like I was always close to understanding but still not quite getting it. Sure – some of the examples I read made sense but then I’d find another one that didn’t. In my quest to understand them, I spent a lot of time reviewing a lot of examples and asking a lot of very patient friends for help. At this point, I feel like I know enough to try and explain the topic in a manner that might hopefully help someone else who was having a hard time with the concept. With my learning philosophy out of the way, let’s jump right in….
I want to jump right into a real (albeit not super useful) example of decorators using the full decorator (or shorthand) syntax. Let’s start with this…
def a_decorator(a_function):
print("You've been decorated!")
return a_function
@a_decorator
def print_name_string(your_name):
name_string = "Your name is: " + your_name
return name_string
print(print_your_name("Jon"))
