How to Add Approval Steps to Ansible Tower Workflows

Suppose you have a workflow set up in Red Hat Ansible Tower with several steps and needed another user to view and approve some or all of the nodes in the workflow.  Or maybe a job is running inside of a workflow but it should be viewed and approved within a specific time limit, or else get canceled automatically?  Perhaps it would be useful to be able to see how a job failed before something like a cleanup task gets set off?  It is now possible to insert a step in between any job template or workflow within that workflow in order to achieve these objectives.

Worth Reading: Apple II Had the Lowest Input Latency Ever

It's amazing how heaping layers of complexity (see also: SDN or intent-based whatever) manages to destroy performance faster than Moore's law delivers it. The computer with lowest keyboard-to-screen latency was (supposedly) Apple II built in 1983, with modern Linux having keyboard-to-screen RTT matching the transatlantic links.

No surprise there: Linux has been getting slower with every kernel release and it takes an enormous effort to fine-tune it (assuming you know what to tune). Keep that in mind the next time someone with a hefty PPT slide deck will tell you to build a "provider cloud" with packet forwarding done on Linux VMs. You can make that work, and smart people made that work, but you might not have the resources to replicate their feat.

BrandPost: How to Deliver Affordable and Optimized Application Access Worldwide with SASE

Global expansion is a common goal for many enterprises. In some verticals, like manufacturing, running production lines globally is an established practice. However, deploying international sales, service, and engineering teams is becoming the norm for many other sectors including high tech, finance, retail, and more.A global enterprise footprint creates a unique set of challenges that do not occur in regional businesses. Users in a remote office will need to securely access data-center applications, cloud applications, or both. Depending on the distance between the remote location and the application—and the sensitivity of the application to high latency, packet loss, and jitter—an expensive set of technologies and capabilities will be needed to optimize the user experience.To read this article in full, please click here

PostgreSQL Connection Pooling: Part 2 – PgBouncer

When it comes to connection pooling in the PostgreSQL world, PgBouncer is probably the most popular option. It’s a very simple utility that does exactly one thing – it sits between the database and the clients and speaks the PostgreSQL protocol, emulating a PostgreSQL server. A client connects to PgBouncer with the exact same syntax it would use when connecting directly to PostgreSQL – PgBouncer is essentially invisible.

Accelerating UDP packet transmission for QUIC

This was originally published on Perf Planet's 2019 Web Performance Calendar.

QUIC, the new Internet transport protocol designed to accelerate HTTP traffic, is delivered on top of UDP datagrams, to ease deployment and avoid interference from network appliances that drop packets from unknown protocols. This also allows QUIC implementations to live in user-space, so that, for example, browsers will be able to implement new protocol features and ship them to their users without having to wait for operating systems updates.

But while a lot of work has gone into optimizing TCP implementations as much as possible over the years, including building offloading capabilities in both software (like in operating systems) and hardware (like in network interfaces), UDP hasn't received quite as much attention as TCP, which puts QUIC at a disadvantage. In this post we'll look at a few tricks that help mitigate this disadvantage for UDP, and by association QUIC.

For the purpose of this blog post we will only be concentrating on measuring throughput of QUIC connections, which, while necessary, is not enough to paint an accurate overall picture of the performance of the QUIC protocol (or its implementations) as a whole.

Indian Community Making the Right Connections

In the lead up to last month’s Internet Engineering Task Force meeting in Singapore, IETF 106, the India Internet Engineering Society (IIESoc) held its third annual Connections conference in Kolkata, India.

This pre-IETF event aims to increase participation in IETF discussions from the Asia-Pacific region, specifically India.

Like the years before it, this edition of Connections had four technology tracks across two days; the themes of which – IoT, security, routing, and research – were chosen with the audience and location in mind, given Kolkata is a major research hub in India. As such, there was record participation, with a large number of local students attending the event, many of whom were excited to learn about, discuss and contribute to the work being considered in the IETF and how they can contribute to this group.

The Importance of Being Involved

A feature of past Connections events has been the participation of IETF working group chairs and RFC contributors attending en route to the impending IETF conference. This year was no different and we were grateful to have former IETF chair, Fred Baker, who presented the keynote and shared his journey at the IETF during the meet and greet session.

Synology Running Out Of Space? Empty The Recycle Bin.

While performing end-of-year clean up on lab infrastructure, I discovered my 8 disk Synology array with about 22TB of usable storage was almost out of space. Really? What had I filled all that space with?

After a lot of digging around, I found that I had enabled the Recycle Bin on one or more Shared Folders, but had NOT created a Recycle Bin emptying schedule.

This means that over several years of shoving lots of data through the array, the various Recycle Bins attached to various Shared Folders had loaded up with cruft. I figured this out running a Storage Analyzer report.

To get my space back, the solution was to empty the Recycle Bin. One way to do that is to edit the properties of a Shared Folder and click “Empty Recycle Bin”. You’ll get a sense of relief as Storage Manager shows available space growing as the Synology removes however many million files you’ve been composting for however long.

However, I like to solve problems permanently. No one has time to manually empty recycle bins on a disk array in a distant rack. Manually. Like a savage. Yuck.

Automating a recycle bin task on a Synology box is Continue reading

How AppArmor can protect your Linux system

AppArmor is a useful Linux security module that can restrict the file-system paths used by an application.It works differently than Security-Enhanced Linux (SELinux) and cannot run on at the same time on the same system with SELinux, which comes installed on some Linux distributions.The question is when to use AppArmor and what it can do to protect your system.This 2-Minute Linux Tip video below is an introduction to AppArmor and how to get starting using it.

We’re Back

It’s been a while but we’re back and it feels great. In this episode I talk about the status of the show, where the heck I’ve been, and where we are headed. I also share my personal story on burnout and some of the lessons I learned along the way.

In the episode I mention the fantastic Denise Fishburn and a video she did on burnout that helped me realize what I was dealing with. That video is embedded below.

Prototyping optimizations with Cloudflare Workers and WebPageTest

This article was originally published as part of  Perf Planet's 2019 Web Performance Calendar.

Have you ever wanted to quickly test a new performance idea, or see if the latest performance wisdom is beneficial to your site? As web performance appears to be a stochastic process, it is really important to be able to iterate quickly and review the effects of different experiments. The challenge is to be able to arbitrarily change requests and responses without the overhead of setting up another internet facing server. This can be straightforward to implement by combining two of my favourite technologies : WebPageTest and Cloudflare Workers. Pat Meenan sums this up with the following slide from a recent getting the most of WebPageTest presentation:

So what is Cloudflare Workers and why is it ideally suited to easy prototyping of optimizations?

Cloudflare Workers

From the documentation :

Cloudflare Workers provides a lightweight JavaScript execution environment that allows developers to augment existing applications or create entirely new ones without configuring or maintaining infrastructure.A Cloudflare Worker is a programmable proxy which brings the simplicity and flexibility of the Service Workers event-based fetch API from the browser to the edge. This allows a worker to Continue reading
