Mastodon Needs More Brand Support

As much as I want to move over to Mastodon full time, there’s one thing I feel that is massively holding it back. Yes, you can laud the big things about federations and freedom as much as you want. However, one thing I’ve seen hanging out in the fringes of the Fediverse that will ultimately hold Mastodon back is the hostility toward brands.

Welcoming The Crowd

If you’re already up in arms because of that opening, ask yourself why. What is it about a brand that has you upset? Don’t they have the same right to share on the platform as the rest of us? I will admit that not every person on Mastodon has this outward hostility toward companies. However I can also sense this feeling that brands don’t belong.

It reminds me a lot of the thinly veiled distaste for companies that some Linux proponents have. The “get your dirty binary drivers out of my pristine kernel” crowd. The ones that want the brands to bend to their will and only do things the way they want. If you can’t provide us the drivers and software for free with full code support for us to hack as much Continue reading

Bosch to acquire TSI Semiconductor, invest $1.5 B post acquisition

German engineering and technology firm Bosch has announced its intent to acquire US-based chipmaker TSI Semiconductors and invest $1.5 billion over the next few years to tap the rising demand for chips globally, especially in the automotive and electronics sector.“With the acquisition of TSI Semiconductors, we are establishing manufacturing capacity for silicon carbide (SiC) chips in an important sales market while also increasing our semiconductor manufacturing, globally,” Stefan Hartung, chairman of the Bosch board of management, said in a statement.Neither of the companies disclosed the cost of acquisition or the terms.Silicon carbide semiconductors can operate at higher temperatures, voltages, and frequencies compared to other semiconductors, making them more efficient for use across solar-powered devices, electric vehicles, aerospace applications, and other applications such as 5G.To read this article in full, please click here

Why Is OSPF (and BGP) More Complex than STP?

I got this question from one of my readers:

Why are OSPF and BGP are more complex than STP from a designer or administrator point of view? I tried everything to come to a conclusion but I couldn’t find a concluded answer, ChatGPT gave a circular loop answer.

There are numerous reasons why a protocol, a technology or a solution might be more complex than another seemingly similar one (or as Russ White would have said, “if you haven’t found the tradeoffs, you haven’t looked hard enough”):

Your decommissioned routers could be a security disaster

Here's bad news: It's easy to buy used enterprise routers that haven’t been decommissioned properly and that still contain data about the organizations they were once connected to, including IPsec credentials, application lists, and cryptographic keys.“This leaves critical and sensitive configuration data from the original owner or operatoraccessible to the purchaser and open to abuse,” according to a white paper by Cameron Camp, security researcher, and Tony Anscombe, chief security evangelist, for security firm Eset (See: Discarded, not destroyed: Old routers reveal corporate secrets).To read this article in full, please click here

The Pure Unification Of Block And File Storage

Companies have been working for years to pull together block, file, and object storage under a single umbrella, giving enterprises that are at times dealing with petabytes of data spread across datacenters, the cloud, and the edge a simpler way to manage, organize, and access all that information. …

Keeping Large Language Models From Running Off The Rails

The heady, exciting days of ChatGPT and other generative AI and large-language models (LLMs) is beginning to give way to the understanding that enterprises will need to get a tight grasp on how these models are being used in their operations or they will risk privacy, security, legal, and other problems down the road. …

Calico’s 3.26.0 update unlocks high density vertical scaling in Kubernetes

Kubernetes is a highly popular and widely used container orchestration platform designed to deploy and manage containerized applications at a scale, with strong horizontal scaling capabilities that can support up to 5,000 nodes; the only limit in adding nodes to your cluster is your budget. However, its vertical scaling is restricted by its default configurations, with a cap of 110 pods per node. To maximize the use of hardware resources and minimize the need for costly horizontal scaling, users can adjust the kubelet maximum pod configuration to increase this limit allowing more pods to run concurrently on a single node.

To avoid network performance issues and achieve efficient horizontal scaling in a Kubernetes cluster that is tasked to run a large number of pods, high-speed links and switches are essential. A reliable and flexible Software Defined Networking (SDN) solution, such as Calico, is also important for managing network traffic efficiently. Calico has been tested and proven by numerous companies for horizontal scaling, but in this post, we will discuss recent improvements made to help vertical scaling of containerized applications to just work.

For example, the following chart illustrates the efficiency achieved with the improvements of vertical scaling in Calico 3. Continue reading

Day Two Cloud 192: OpenTelemetry – Getting From Visibility To Observability With Ben Hall

OpenTelemetry is an open-source project that brings together tools, SDKs, and APIs for collecting telemetry--that is, logs, metrics, and traces---in a standardized way. The goal of the project is to help developers and operators instrument highly distributed applications and services to understand dependencies, monitor performance, and quickly troubleshoot problems. On today's Day Two Cloud podcast we explore OpenTelemetry and how it works. We also discuss the difference between visibility and observability, and why this matters. Our guest is Ben Hall.

Is Dynamic MAC Learning Better Than EVPN?

One of my readers worried about the control-plane-induced MAC learning lag in EVPN-based networks:

In all discussions about the advantages/disadvantages of VXLAN/EVPN, I can’t find any regarding the lag in learning new macs when you use the control plane for mac learning.

EVPN is definitely slower than data plane-based dynamic MAC learning (regardless of whether it’s done in hardware or software), but so is MLAG.
