No,it is not to isolate malicious devices! It is because you have lots of “old” device that does not handle and will not connect to your main combined WiFi 5/6 network. You need a 2.4 Ghz network. I have only managed to get a stable connection to Raspbery Pi Zero on the 2.4 Ghz only network.
Exploring deployment options for a web app with a focus on cost, speed, and learning.
I use GitHub Copilot (Pro) and Google Gemini CLI1. Do coding assistants help me develop faster, improve code, or cause other effects? Disclaimer: The way we use AI assisted development will continue to evolve and these are my thoughts and experiences with coding assistants as of November 2025. I expect to look back on this post and feel embarrassed - but that’s part of the journey. I use AI coding assistants in different ways, each with its own impact. ...
This is how I manage my SSH private keys. I think this is a good balance between security and usability, but this setup is for me. Your situation may be different so read this as potential inspiration, not as a blueprint. I have a “master” key that gives access to all the clouds, linux machines and Git/GitHub. This gives lots of access so it must be protected. But I also use it often, so it must be easy to use. The way I solve this is using 1Password. It allows the keys to be used on multiple devices while keeping them secure through biometric authentication. ...
A long time ago my employer needed to sign a shrink-wrapped software package using Authenticode. This was my first experience with code signing. Below I summarize what code signing is, why it matters, the 2023 HSM requirements, and practical options for signing in local and CI environments. I have used Azure Key Vault for HSM-backed signing. What is code signing and why use it? A digital signature is an encrypted checksum of a file. It can be verified with the public key to ensure the file was not modified after signing and that the signer controls the corresponding private key. ...
