So recently I had to play with BGP after a very long time. I have a router that connects to external via an eBGP session. It gets default route from there and it advertises the originating prefixes. All worked great until I wanted to advertise a new /24 subnet. The problem was that I have this subnet split into many /27s on different SVIs, and even though I’ve included it in the prefix-list to be advertised over the BGP session, this would not come up. ...

In this one I will show you how I improved the performance of a WordPress site using CloudFlare Caching and PHP FPM pool settings. But a bit of context. I have 2 WP websites running on the same VPS behind nginx, with 2 different conf file. Pretty standard deployment so far. On this VPS I have root access, so I’m able to play a bit more with other stuff, not just standard cPanel settings. ...

For context, there’s a setup with 3 identical environments on the customer side and a local lab that was recently replaced. I’ve deployed a new Openshift cluster (version 4.14. will become important later) to replace another lab environment in a different location. ...

First I’ve connected to https://copilot.microsoft.com with both a personal account and a work account. I’ve tested the announcement of this by asking it directly: What we can see quickly is that my company-linked account has to update to latest Copilot because it still uses GPT4 as a LLM. While the official Copilot uses the latest model. Even though it doesn’t respond directly like its previous model. ...
