Vini Motta decided to use AI on ipSpace.net content to find what it would recommend as the projects to work on in order to become employable in 2025. Here are the results he sent me; my comments are inline on a gray background.
While the hyperscalers and big cloud builders all are racing as fast as they can to build the biggest – and presumably the best – models, or collections of models, to win the AI race and become the Microsoft or Red Hat of commercial-grade models, the acquisition of AI hardware and envelope pushing on AI model architecture is not indicative of the adoption of AI by enterprises. …

Hewlett Packard Enterprise last summer introduced the first of its Gen12 ProLiant systems, packed with Nvidia’s latest GPU accelerators and aimed squarely at the rapidly expanding AI space that in less than two years went from prompt-and-respond chatbots to AI agents that can reason, plan, and collaborate on their own. …

In the previous blog post, I described the usual mechanisms used to connect virtual machines or containers in a virtual lab, and the drawbacks of using Linux bridges to connect virtual network devices.
In this blog post, we’ll see how KVM/QEMU/libvirt/Vagrant use UDP tunnels to connect virtual machines, and how containerlab creates point-to-point vEth links between Linux containers.
Nvidia may be shipping its “Blackwell” B100, B200, and GB200 compute engines, but not in enough volumes for server maker Supermicro to meet its revenue expectations in the quarter ended in December. …

Now that 2025 has been here for a few weeks and 2024 has closed with a variety of year-end traditions — from Christmas and Hanukkah celebrations to New Year’s Eve (NYE) countdowns, as well as celebrations of Orthodox Christmas, and Lunar/Chinese New Year — let’s examine how these events have shaped online behavior across continents and cultures. Reflecting on Christmas and NYE 2024 provides insights into how these trends compared with those of the previous year, as detailed in an earlier blog.
One notable finding is the remarkable consistency in human online patterns from one year to the next, a trend that persists despite cultural differences among countries. Data from over 50 countries reveal how people celebrated in 2024–2025, offering a timely reminder of typical holiday trends. While Christmas remains a dominant influence in many regions, other cultural and religious events — such as Hanukkah and local festivities — also shape online habits where Western traditions hold less sway.
In regions where Christmas is deeply rooted, Internet traffic dips significantly during Christmas Eve dinners, midnight masses, morning gift exchanges, and Christmas Day lunches, a pattern evident in both our previous and current analyses.

Despite many advantages of Segment Routing, some networks still prefer to use RSVP for traffic engineering – and they can have good reasons for this. Is there any value of SDN controller with RSVP-TE, compared to configuring policies on each …
It all started with a netlab issue describing different interpretations of VLAN 1 in a trunk. While Cumulus NVUE (the way the netlab configuration template configures it) assumes that the VLAN 1 in a trunk is tagged, Arista EOS assumes it’s the native VLAN.
At that point, I should have said, “that’s crazy, we shouldn’t allow that” and enforce the “VLAN 1 has to be used as a native VLAN” rule. Alas, 20/20 hindsight never helped anyone.
TL&DR: Do not use VLAN 1 in VLAN trunks; if you have to, use it as a native VLAN.
Have you ever wondered how to navigate the complexities of managing Kubernetes clusters effectively? Observability is the key, and Elasticsearch plays a pivotal role in storing and analyzing the critical data that keeps your systems running smoothly.
In this blog post, we will delve into the essential aspects of observability within Kubernetes clusters powered by Calico eBPF data plane, highlighting the significance of Elasticsearch in this ecosystem. We’ll explore how Calico leverages Elasticsearch to enhance both observability and security, providing a comprehensive guide to common issues, best practices, and troubleshooting tips. You will understand the value of observability on a Kubernetes cluster and how to keep Elasticsearch healthy by storing and making observability data available. By the end, you’ll be equipped with the knowledge to maintain a robust and efficient Elasticsearch setup, ensuring optimal performance and security for your Kubernetes cluster powered by Calico eBPF data plane.
We will discuss what Elasticsearch is, why it matters, and how Calico Enterprise utilizes it to provide unparalleled observability. Whether you’re dealing with common issues or looking to implement best practices, this guide will serve as your reference guide to maintain a healthy Elasticsearch setup.
After only a little more than a year of running Intel’s Data Center and AI group – which is probably about as much fun right now as falling down the stairs – Justin Hotard has departed the chip maker to become the next chief executive officer of Nokia, which interestingly enough has a renewed interest in building cloud networks and making money at that. …

Cloudflare was recently contacted by a group of anonymous security researchers who discovered a broadcast amplification vulnerability through their QUIC Internet measurement research. Our team collaborated with these researchers through our Public Bug Bounty program, and worked to fully patch a dangerous vulnerability that affected our infrastructure.
Since being notified about the vulnerability, we've implemented a mitigation to help secure our infrastructure. According to our analysis, we have fully patched this vulnerability and the amplification vector no longer exists.
QUIC is an Internet transport protocol that is encrypted by default. It offers equivalent features to TCP (Transmission Control Protocol) and TLS (Transport Layer Security), while using a shorter handshake sequence that helps reduce connection establishment times. QUIC runs over UDP (User Datagram Protocol).
The researchers found that a single client QUIC Initial packet targeting a broadcast IP destination address could trigger a large response of initial packets. This manifested as both a server CPU amplification attack and a reflection amplification attack.
When using TCP and TLS there are two handshake interactions. First, is the TCP 3-way transport handshake. A client sends a SYN packet to a server, it responds with Continue reading

We know that in Palo Alto, or in any NGFW, we can allow or block various URL categories. Speaking specifically about the Palo Alto firewall, let's say you have a strict URL filtering policy and decide to block the 'Shareware and Freeware' category.
When you do this, you'll likely have frustrated users complaining that they can't access sites like GitHub, for example.
So, what did I do now to cause another network issue? Well, Palo Alto categorizes github.com as 'Shareware and Freeware', so the firewall simply blocks it. There’s a high chance that many other useful sites will get blocked too.
A quick fix is to create a Custom URL Category and add the GitHub URL to it. However, this isn’t a scalable solution.
For instance, if I start with *.github.com, the firewall may block github.com. Then, if I add github.com, the firewall might block URLs like www.github.githubassets.com. To address this, I’d need to use a different wildcard, but we can’t keep doing this for every affected site.
Instead of managing each URL individually like before, we Continue reading
