I’ve encountered two basic philosophies for responding to requests to join a project. One philosophy I’ll describe as “Default Yes”. The argument goes, “If someone brings you a request, say yes! You only grow with challenges and if you say no too much, people will stop asking.” The second philosophy could be called “Default No.” […]

Take a Network Break! This week we cover new cloud networking capabilities from Prosimo, discuss Broadcom's latest version of the Jericho ASIC which is being positioned for network fabrics for AI workloads, and explore the latest version of the open-source Dent network OS. We also cover financial results from F5, Starlink price cuts, and more tech news.

Today, we are thrilled to announce VMware Secure App IX, a new offering designed to help cloud IT and Cloud Center of Excellence (CCoE) teams achieve borderless governance and compliance by securely connecting applications in multi-cloud environments and application teams and lines of business (LOB) by accelerating their digital transformation initiatives.
Enterprises are increasingly running applications in the cloud to drive innovation, agility, and growth. As organizations adopt multi-cloud strategies to leverage the strengths of different cloud providers, they face new challenges with ensuring secure and compliant application connectivity across clouds and platforms.
In their drive to innovate and compete, enterprises have embraced multiple cloud environments. Multi-cloud adoption has increased the need for seamless and secure application connectivity across disparate clouds, app workloads, data services, and application architectures.
Cloud IT and Cloud Center of Excellence (CCoE) teams must address many complex requirements when providing secure connectivity for applications running in the cloud. Let’s look at some of these requirements in more detail.
Enterprise application modernization is an ongoing process rather than a one-time event. As new technologies emerge and business needs evolve, enterprises must continually update and modernize their Continue reading
The perimeter of networks is changing and collapsing. In a zero trust network, no one and no thing is trusted from inside or outside of the enterprise network without verification or network access control (NAC). However, for years, organizations have been saddled with bolt-on NAC technologies that deliver cost complexity while failing to be effective. Instead, security-conscious organizations are shifting to a “microperimeter” enterprise that embeds security into the network infrastructure as the proactive way to defend today’s wider attack surface.
Anne Baretta decided to use netlab to test a proposed DMVPN topology. As netlab doesn’t support DMVPN (and probably never will), he decided to use netlab capabilities to start the lab topology and perform initial configuration, adding DMVPN configuration commands as custom configurations. Here’s how he described the process:
In this case I used netlab as a quick way to get a topology up and running, and then add the DMVPN configuration by hand.

glibc is annoyingly eager to break userspace. You can’t just build something that only depends on libc and expect it to work on all linux systems of that architecture.
I don’t know why Linus Torvalds keeps insisting “we do not break userspace” as a policy for the kernel when libc seems to make that exact thing a hobby. And either way the userspace programs break.
Compiling static (including libc) is frowed upon, and has even had known breakages left unaddressed.
E.g. setlocale() had a strange bug where for new threads you had to
first set the locale to the wrong locale, and then call it again to
set it to the right one. Otherwise the new thread would be in a weird
state where the local is wrong, but it thought it’s right, so won’t
allow you to change it to what it thought it already was.
I can’t find the bug now (I ran into this around 2004-2005), but the official response was basically “well don’t compile statically, then”.
And DNS can be broken with static glibc. “a statically linked glibc can’t use NSS (Name Service Switch) modules from a different glibc version, so if you statically link Continue reading
Once upon a time it was popular to put a counter on your web page, to show how many people had visited the site before you. I thought it be more fun, and less bragging about how long the page has existed, if it just showed who’s reading it now.
As I mentioned in a previous post, I’m learning Rust. My teaching project has been to make this web widget that shows the current number of browsers that that have the page open.
You see this counter here on the blog in the top right.
The idea is pretty simple. Have some javascript open a websocket to a server, and stream down messages with the current count, as it changes. When a client connects or disconnects, inform all other clients of the new total.
This does mean that it needs to keep one TCP connection open per client, which may be too costly for some sites. Especially since I’m putting it behind an nginx, so the machine needs to keep 3x the state.
I’m not logging anything to disk, nor sharing anything between the clients except for the current count. It’s just an amusing publicly visible presence counter.
Actually, because Continue reading
A new report from analyst firm Omdia suggests operators’ best chance of growth in the consumer market comes from partnering with Big Tech.
s like for a traditional media outlet to go up against the vast agglomeration of economic and digital power known as Big Tech—and to do so without the benefit of what economist John Kenneth Galbraith defined as countervailing power.
