Worth Reading: AI Does Not Help Programmers

On the Communications of the ACM web site, Bertrand Meyer argues that (contrary to the exploding hype) AI Does Not Help Programmers:

As a programmer, I know where to go to solve a problem. But I am fallible; I would love to have an assistant who keeps me in check, alerting me to pitfalls and correcting me when I err. A effective pair-programmer. But that is not what I get. Instead, I have the equivalent of a cocky graduate student, smart and widely read, also polite and quick to apologize, but thoroughly, invariably, sloppy and unreliable. I have little use for such supposed help.

Not surprisingly, my experience is pretty close to what he’s describing. AI is the way to go if you want something that looks reasonable (at a first glance), but not if you want to get something right. Unfortunately, there’s a bit of a difference between marketing and engineering: networks that are configured 90% correctly sometimes fail to do what you expect them to do.

AskJJX: Help! Office Wi-Fi is So Bad An Intern Is Following The CEO Around With An AP

AskJJX: How do you set up and configure Wi-Fi for a two-level office in a crowded office building area (downtown San Francisco across from Moscone Center) with concrete poles all over the place? It was a nightmare. APs were dropping traffic like flies. We were at the point of almost having an intern follow the […]

Enterprises can use multiple DNS providers to serve their zone. This increases the reliability of the service and will likely help them to keep their zone available if one provider is suffering from a critical failure.


According to the Astrix Security Research Group, mid size organizations already have, on average, 54 Generative-AI integrations to core systems like Slack, GitHub and Google Workspace and this number is only expected to grow.


With browser fingerprinting, many pieces of data can be collected about a user’s web browser and device, such as screen resolution, location, language, and operating system. When you stitch these pieces together, they reveal a unique combination of information that forms every user’s visitor ID or “digital fingerprint.

Cisco urges stop using weak crypto algorithms with OSPF

To reduce the risk of service problems, Cisco is making it harder for organizations to use weak cryptographic algorithms when setting up authentication for OSPF packets on certain Catalyst Edge Platforms and Integrated Services Routers (ISR).Newer versions of Cisco’s IOS XE software (Release 17.11.1 and later) no longer support those algorithms—DES, 3DES, and MD5—by default, Cisco stated in a field Notice.Specifically, the algorithms are no longer default options for the open shortest path first v 3 (OSPFv3) protocol, which uses the IPsec secure socket API to add authentication to OSPFv3 packets that distribute routing information.To read this article in full, please click here

Is The OSI Model Good For Understanding How Networks Work? Not Really

Looking back at my career in network engineering, beyond some basic concepts and naming conventions, I cannot remember using the OSI model once. Not for troubleshooting, not for protocol design. I have used the concept of layering, but never the OSI model specifically.

VMware picks up partners for open-source confidential computing development

Virtualization technology provider VMware has announced that it is partnering with AMD, Samsung, and members of the RISC-V keystone community for the development and operations of confidential computing applications.RISC-V is a hardware standards organization that is designing low-power processors; the Keystone Enclave is an open source project for building customizable trusted execution environments (TEEs).The aim of the new partnership among VMware, AMD, Samsung and RISC-V participants is to collaborate to contribute to the open-source Certifier Framework project for confidential computing. The Certifier Framework is an open-source project started by VMware in 2022 to tackle the key barriers in the development of confidential computing applications.To read this article in full, please click here

Hedge 184: Open Source Value, Fake Agile, Cloud & Skills

It’s roundtable time at the Hedge! This month, Tom, Eyvonne, and Russ kick off the conversation talking about the value (and some dangers) of open source software. Fake Agile is up next—what does it really mean to be agile, and can organizations use agile tools without being truly agile? Finally, cloud computing, vendors, and skills come to the fore.

Kubernetes Unpacked 029: Kubernetes And Certifications For Product Managers

In this episode, Michael catches up with Anton Smith, Head Of Product at Spectro Cloud. This episode goes outside of the standard engineering conversation and into a conversation of why it makes sense for Technical Product Managers (TPMs) to not only get a certification like the Certified Kubernetes Administrator (CKA), but why staying technical as a TPM in the Kubernetes space helps you with your job.

Book Review: Model-Driven DevOps

Earlier this month at Cisco Live in Las Vegas, I attended a presentation by Steven Carter and Jason King titled Model-Driven DevOps: The Enterprise Automation Framework You've Been Looking For! They discussed the importance of robustly modeling your network data — a quality very dear to me, as you might expect — and having a clear strategy for automating changes, and shared an example automation architecture for reference. It was a refreshing take on introducing network engineers to DevOps methodologies, and the first time I've seen anyone clearly map software development practices to network automation.

Interested to dive deeper into the material than a 45-minute session would allow, I was pleased to learn that their talk derived from a book of the same name that they co-authored. Coupled with the lingering geeky high from Cisco Live, it made for an excellent read on the flight back home.

The book's content is broken into seven easily digestible chapters, each dedicated to a particular step along a path toward network automation:

  • Chapter 1: A Lightbulb Goes Off
  • Chapter 2: A Better Way
  • Chapter 3: Consumable Infrastructure
  • Chapter 4: Infrastructure as Code
  • Chapter 5: Continuous Integration/Continuous Deployment
  • Chapter 6: Implementation
  • Chapter 7: Human Continue reading

Hasura Launches New Data Network for APIs Only

Data networks are generally used for file sharing, application operations or internet access, but what about a network strictly for distributing application programming interfaces? After all, an API is pretty esoteric, given that it is not standard data but a set of rules that define how two pieces of software can interact with each other. Well, that out-of-the-ordinary system now exists, and it’s designed to do a ton of heavy lifting behind the scenes that developers will appreciate. Bangalore- and San Francisco-based Hasura DDN, a new edge network using Graph Query Language and designed for transporting real-time, streaming and analytical data. It enables developers to run low-latency/high-performance data APIs at a global scale, with no additional effort and no additional fees, according to the company. Hasura CEO and co-founder

Cisco firewall upgrade boosts visibility into encrypted traffic

The software that runs Cisco’s new Firewall 4200 Series now includes the ability to see into encrypted traffic without decrypting it, which the vendor says will allow enterprise customers to better protect hybrid and multicloud applications.The enhanced Cisco Encrypted Visibility Engine (EVE) is part of the 7.4 version of the Secure Firewall operating system. Version 7.4 also includes zero-trust capabilities and improved application access control. The 4200 Series’ operating system also helps improve overall firewall performance – it’s twice as fast as previous high-end Cisco firewalls, the company says.EVE, which has been available since version 7.2 of the software, takes things further than traditional firewalls because it now lets customers detect the client application within an encrypted tunnel, according to Rick Miles, vice president of product management, cloud and network security in Cisco’s security business group.To read this article in full, please click here
