The Art of Saying “No”

No.

It’s the shortest sentence in the English language. It requires no other parts of speech. It’s an answer, a statement, and a command all at once. It’s a phrase that some people have zero issues saying over and over again. And yet, some others have an extremely difficult time answering anything in the negative.

I had a fun discussion on twitter yesterday with some friends about the idea behind saying “no” to people. It started with this tweet:

Coincidentally, I tweeted something very similar to what Bob Plankers had tweeted just hours before:

The gist is the same though. Crazy features and other things that have been included in software and hardware because someone couldn’t tell another person “no”. Sadly, it’s something Continue reading

Ten challenges for making automation a ‘team player’ in joint human-agent activity

Ten challenges for making automation a ‘team player’ in joint human-agent activity, Klein et al., IEEE Computer Nov/Dec 2004

With thanks to Thomas Depierre for the paper suggestion.

Last time out we looked at some of the difficulties inherit in automating control systems. However much we automate, we’re always ultimately dealing with some kind of human/machine collaboraton. Today’s choice looks at what it takes for machines to participate productively in collaborations with humans. Written in 2004, the ideas remind me very much of Mark Burgess’ promise theory, which was also initially developed around the same time.

Let’s work together

If a group of people (or people and machines) are going to coordinate with each other to achieve a set of shared ends then there are four basic requirements that must be met to underpin their joint activity:

  1. They must agree to work together (the authors call this agreement a Basic Compact).
  2. They must be mutually predictable in their actions
  3. They must be mutually directable.
  4. They must maintain common ground.

A basic compact is…

… an agreement (often tacit) to facilitate coordination, work toward shared goals, and prevent breakdowns in team coordination. This Compact involves a commitment Continue reading

DIY communications networks to trend in 2020, says major telco

Communications networks without a centralized infrastructure will become more popular this year as folks become increasingly aware of data collection from governments and tech companies, says telecommunications provider Telenor Group.The company refers to fully encrypted mesh and peer-to-peer apps as the technology that will enable these consumer-level “off-the-grid, build-it-yourself” links. Mesh apps will also be useful in disasters where traditional networks fail.[Get regularly scheduled insights by signing up for Network World newsletters.] “Communicating without a central coordinating network is appealing to people for many reasons, and in 2020, we expect to see more go that route, especially in conflict situations, to mobilize for protests, and simply to stay below the radar,” the company says on its website.To read this article in full, please click here

Aruba reinforces SD-Branch with security, management upgrades

Aruba has taken steps to bolster the security and manageability of its branch-office networking package for customers with lots of branch sites.The HPE company enhanced its SD-Branch software with identity-based attack detection and intrusion prevention, and improvements to its SD-WAN Orchestrator to make it easier to deploy security features on a large scale.See predictions about what's big in IT tech for the coming year. Aruba’s SD-Branch software runs on its branch gateways and includes a variety of integrated features like a firewall that support LAN, WAN, Wi-Fi networks, and segmentation as well integration with the company’s ClearPass policy-management software and its cloud-based package Aruba Central.

IPv6 Buzz 042: Why Wireless Is A Smart Place To Start With IPv6

If you're looking for a way to bring IPv6 into your environment, the WLAN may be your best bet. Find out why in the latest episode of IPv6 Buzz with guest Jeffry Handal. Jeffry cut his teeth with an early v6 deployment on the wireless network of Louisiana State University (LSU). This WLAN serves 40,000 users and over 100,000 devices. He shares his experiences and talks about how vendor adoption of v6 had advanced since that deployment.

Strong Encryption Is Central to Good Security – India’s Proposed Intermediary Rules Puts It at Risk

Security and encryption experts from around the world are calling on the Indian Ministry of Electronics and Information Technology (MeiTy) to reconsider proposed amendments to intermediary liability rules that could weaken security and limit the use of strong encryption on the Internet. Coordinated by the Internet Society, nearly thirty computer security and cryptography experts from around the world signed “Open Letter: Concerns with Amendments to India’s Information Technology (Intermediaries Guidelines) Rules under the Information Technology Act.”

MeiTy is revising proposed amendments to the Information Technology (Intermediaries Guidelines) Rules. The proposed amendments would require intermediaries, like content platforms, Internet service providers, cybercafés, and others, to abide by strict, onerous requirements in order to not be held liable for the content sent or posted by their users. Freedom from intermediary liability is an important aspect of communications over the Internet. Without it, people cannot build and maintain platforms and services that have the ability to easily handle to billions of people.

The letter highlights concerns with these new rules, specifically requirements that intermediaries monitor and filter their users’ content. As these security experts state, “by tying intermediaries’ protection from liability to their ability to monitor communications being sent across their platforms or systems, the amendments would limit Continue reading

How to Add Approval Steps to Ansible Tower Workflows

Blog_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
