I wanted to flash a Sonoff NSPanel the other day and my FTDI started doing weird things, brownouts and garbage on the line. Rather than digging through the drawer for a better one, plan B : the NodeMCU sitting right there.
Read MoreIn this guide we’ll walk through setting up Tailscale’s experimental Identity Provider (tsidp) inside a lightweight Debian Proxmox container. We’ll create the container, install Go, build the binary, configure systemd with environment variables, and run tsidp as a dedicated user.
This is a very raw howto, copy paste ready, based on my attempts, target audience is homelaber. Comments welcome !
Read MoreI run an Intel NUC Gen 8 boxes (NUC8BEB, NVMe + HDD, 32 GB RAM) in my Proxmox 8 cluster (Issue is the same on PVE9).
I randomly hangs — sometimes in 15 min, sometimes after a few hours. No ping, no display, useless logs.
Recently migrated my homelab ESXi to Proxmox VE, and while things mostly went smoothly, one node would randomly hang (mostly during large transfers or under sustained network load but sometimes when idling...).
I plugged in a monitor to check logs and... confirmed the cause with a quick dmesg:
e1000e: Detected Hardware Unit Hang
Turns out this has been a known issue for years with Intel e1000e NICs (like I217-LM, I219-V, 82574L, etc.). These "aging" chips choke when offload features are enabled under modern workloads.
Read MoreJust discovered something pretty cool while working on email workflows for BookSea that doesn't seem to be widely documented anywhere. You can use "+" signs in test emails !
(Updated 2025 July 30 - Now they use the + signs as normal)
Read MoreSynology DSM won't let you use an SSD plugged into an eSATA port as a cache drive. A single bitmask in the system config decides which ports count as eSATA, and changing it lifts the restriction.
Read MoreWhile troubleshooting a malfunctioning radar system, I wanted to inspect its firmware for diagnostic tools (couldn't find any). The firmware was stored in a Btrfs image, which isn't straightforward to handle on macOS without spending some quality time with FUSE.
To "extract" its contents, I instead used a Docker container with the necessary tools, because it's quite easy to do on plain linux. Here's how.
Read MoreOut of curiosity I'm testing Cursor AI ( and I'm actually enjoying it more that I should ), but I quickly noticed my laptop's battery draining at an alarming rate - faster than playing Factorio. After investigation, the root cause was clear: the Import Cost VS Code extension was triggering excessive CPU usage through repeated recalculations (for no reason?!).
Edit: No reason might seem excessive. It's a TypeScript project and I was working on components that got imported everywhere so I might understand why the sizes needed to be updated, but it's not a BIG project, it still doesn't make sense to eat all the CPU.
Read MoreHere's a straightforward docker-compose setup for running WordPress locally on my M1 Macbook, with persistent data, mapped plugins directory, and custom PHP upload settings. I use it as a Dev environnement but should work for prod with minor changes.
Read MoreHave you ever wished you could send messages where there’s no cell service or when roaming fees are sky-high? Meshtastic makes it possible. This open-source project lets anyone create a mesh network using affordable LoRa radio modules.
It's like setting up a mini-internet that works anywhere. Whether you're hiking in remote areas, attending a packed festival where networks are overloaded, or like us spending time off-grid on a remote island, Meshtastic has you covered.
At its core, Meshtastic combines two technologies: LoRa (Long Range) radio for communication and Protocol Buffers (protobuf) for efficient data packaging. Together, they create a system that sends messages over several kilometers while using minimal power.
In this post, we'll explore how Meshtastic works behind the scenes—how it cleverly routes messages, manages power use, and what makes its mesh networking approach unique. By the end, you'll understand what makes this technology tick, even if you're new to radio communications.
