Woman Alarmed When Her Trusted Therapist Starts Recording Her With AI — Where Is Her Voice Going?

2026-05-302026-05-30 Danie
Two people seated facing each other, one holding a pen and notebook, suggesting a counseling or therapy session.

Don’t get me wrong, I think AI has very many useful things it can be used for. It can also be cloud based or self-hosted. But medical records, personal discussions, and most especially therapy sessions, […]

List of SAR Templates with icons for Found Person, Fire Location, Staging Area, and Object Found, each marked as default.

2026-05-242026-05-24 Danie
Wi-Fi router with three antennas positioned in a homemade reflector made of aluminum foil to boost signal strength.

“The trick sounds like something from a frugal grandparent: put aluminium foil behind your Wi-Fi router to make the signal stronger. For years, tech experts said don’t bother. Then in 2017, researchers at Dartmouth College […]

A LEGO figure with a white shirt and blue pants stands next to stacked blue and gray LEGO bricks on a wooden surface.

“LEGO and 3D printing may seem like a perfect combination, but there’s more to it than first meets the eye. While you can 3D print LEGO blocks, tight tolerances can produce disappointing results if you […]

MeshCore radio network in Cape Town for off-grid communications

2026-05-172026-05-17 Danie
A visually engaging illustration showing a meshcore network connection across an urban landscape. The image is a composite of a photograph and an architectural model, with light-beam graphics connecting key components. A man in the foreground uses a smartphone, labeled "USER NODE (A)." A small circuit board on a balcony next to him is labeled "ESP32 MESHCORE RADIO NODE." A large, dramatic light beam, representing the radio connection, originates from the man's radio node and projects up a nearby mountain to a large communications repeater, which is labeled "MOUNTAIN REPEATER (B)." Another light beam originates from the same mountain repeater and projects into the distance towards another communication node across a large city, labeled "CITY NODE (C)." An illustrative overlay on a table in front of the user displays a simplified tactical map, with lines and letters showing the connections from "A" to "B" to "C." In an inset in the bottom-right corner, another person, with their back to the camera, is shown using an iPad, labeled "TABLET WITH MESHCORE APP." A small radio node with an antenna is positioned next to them. The text "MESHCORE NETWORK CONNECTION" is prominent at the bottom of the graphic, clearly identifying the subject matter.

Many may be familiar with the Meshtastic network which uses cheap LoRa radios (usually linked to a mobile phone app) to send direct text messages or post text messages to a public or private group. […]
