Use powercli to connect to vCloudDirector in ISE (2025-04-30)

Recently my script stopped working to connect to vCloudDirector. I consume vCloudDirector from a managed service company and sometimes the version changes without me knowing or having a simple way to check it. Just now this happened to me again, usually this then means my PowerCLI script starts failing.

I regularly need to consume the latest user agents. I was looking for an API but couldn’t find anything dependable. I came across a self-updating list of the latest and most common user agents seen on the web across all device types, operating systems, and browsers. The data is mostly fresh, theoretically updating weekly.

Tailscale mesh VPN

I’m a big fan of Tailscale ever since I heard about it. I connect my devices, but I always had an issue with not being able to route traffic for specific domains through the exit node. Something like split tunneling via the exit node. The main problem was that I just couldn’t find this feature, and LLMs sent me on a wild goose chase trying to achieve this with network hacks. None of them worked.

What I didn’t know is that this feature has existed for a while and is called App Connectors.

This year, from Tuesday, May 13th to Saturday, May 17th, 2025, the Eurovision Song Contest will take place in Basel. This is also an event that has the potential to attract DDoS actors. I will be keeping a close eye on Noname057(16) activity as this is something that is possible. Additionally, follow the news to see if we can see signs of activity.

News articles from past years indicate that DDoS attacks around the Eurovision Song Contest were a more or less common occurrence.

It’s official: the CA/Browser Forum has voted to approve Ballot SC-081v3, which will significantly reduce TLS certificate lifespans over the next few years. This is a major shift in the web security landscape that will affect millions of website operators.

This is also a show-and-tell of options on how to use and play with Ollama. I tend to use my Ollama as a headless system sending requests via VPN for remote processing on my Ollama macOS.

I’ll help you create a persistent configuration for OLLAMA_HOST on macOS. The most reliable way to do this is to create a LaunchAgent plist file.

Cloudflare as seen by Dall-E

Cloudflare is a global technology company that provides a wide range of internet services and security solutions. Their core offerings include:

Content Delivery Network (CDN) services that help websites load faster by distributing content across a global network of data centers
DDoS (Distributed Denial of Service) protection to defend websites against malicious attacks
Web security features including a Web Application Firewall (WAF), SSL/TLS encryption, and bot management
DNS (Domain Name System) services that help route internet traffic efficiently
Zero Trust security solutions that help organizations secure their networks and applications

Cloudflare has great offerings, a strong API, and many tools. I’m not super familiar with all of Cloudflare’s offerings because I am a free user who has been using it for many years, but I was never much involved in business or enterprise deployments.
