Visual Inspection Perform a thorough visual inspection of the PCB for any obvious signs of damage, such as burn marks, solder bridges, or excessive flux residue. Missing Components Consult your system’s documentation, maybe a component is missing? For the Raspberry Pi Pico, you can find the datasheet here. Pro Tip Raspberry Pi keeps their documentation in here. Damaged Components A reliable diagnostic method is to use a multimeter to measure the resistance between specific nodes, mainly those on the power rails. ...

If you are dealing with data containing numerous duplicates, I highly recommend checking out rdfind. This utility replaces duplicates with symlinks or removes them entirely. If you are looking for deduplication specifically for backups, I suggest addressing the root cause by using BorgBackup. BorgBackup natively handles deduplication, compression, and encryption. My Workflow Consolidate potentially duplicated files into a single location. (Extract all archives first!). Run updatedb to ensure fast indexing with locate. Manually review and remove files that are definitely safe to delete (calculating checksums is time consuming). Note ...

This configuration is doable at the dnsmasq level, which Pi-hole utilizes as its internal DNS. Enable Custom Configuration Ensure your Pi-hole environment is permitted to process custom configuration files in the web panel. Set Environment Variables Set the FTLCONF_misc_etc_dnsmasq_d environment variable to true. For a Docker Compose setup, simply add: environment: ... FTLCONF_misc_etc_dnsmasq_d: true Configure volumes Map your custom configuration into /etc/dnsmasq.d. Using a named volume is the recommended approach: volumes: ... - 'pihole_etc_dnsmasqd:/etc/dnsmasq.d' You can also use a bind mount to map a specific host directory instead of a named volume. ...

I advise against using Winbox, there are issues with it, and that’s not just my personal theory. On the MikroTik download page, a Netinstall tool is available in CLI form. You can use it to install a new RouterOS image, apply a configuration script, and enable SSH immediately. Preparation From MikroTik Download, download Netinstall (CLI Linux) and the Main package (note: the RB750Gr3 uses MMIPS). Set a static IP on your computer (e.g., 192.168.88.x, where x is not 1) and set the default gateway to 192.168.88.1. Running Netinstall In the directory containing your downloaded files, run: ...

The first post on my blog I hope it won’t be the last one. The site you are looking at is a rewrite of my previous portfolio. This site isn’t intended to be just a portfolio, it’s a blog, which serves as an archive of the interesting projects and technical challenges I’ve worked on. I am publishing them with the hope that they might be of use to someone else.
