Connecting a 60GHz mmWave Radar to Home Assistant via MQTT: A Verified Guide

·2 views

A tutorial explains how to link a 60GHz mmWave radar, used for fall detection, presence, or sleep monitoring, to the Home Assistant platform. The radar sends JSON data over MQTT to a broker, which Home Assistant subscribes to and converts into viewable entities on a local dashboard. The guide was tested on Windows 11 using WSL2 and Home Assistant Core 2025.1.4 with a live radar and an Apache Artemis broker. It covers the required broker and radar setup, the topic structure using the device's MAC-based DeviceID, and installation options for Home Assistant, with the HA Core route recommended for Windows.

First-Year CS Student Shares Why He Chose Computer Science and His Goals

Allen, a first-year Bachelor of Science in Computer Science student, explains in a personal blog post why he chose the field. He wants to understand how programs work and how technology fits into everyday life, and he had little programming experience before enrolling. He is currently learning C++, covering variables, data types, input and output, and conditional logic, and he says practice is helping him work through errors. Looking ahead, he hopes to build useful, easy-to-use programs and applications and to gain experience through coursework and personal projects. He also encourages fellow beginners to treat mistakes as part of learning.

EU AI Act: chatbots must disclose AI use, with marking grace period ending 2 December

Since 2 August 2026, Article 50 of the EU AI Act requires products interacting with EU users to disclose AI use, including chatbots disclosing before or during first contact. AI-generated text, images, audio and video must carry machine-readable marks, and deepfakes need visible labels. Systems already on the market before 2 August have until 2 December 2026 to meet the marking requirement. Violations can draw fines of up to 3% of global turnover, and the rules apply regardless of where a company is headquartered. The article also advises mapping AI features, adding disclosure text, and keeping records of disclosures, while noting it is a product pitch offering templates rather than legal advice.

IIMJobs listings can be turned into a spreadsheet for recruiter market research

A recruiter-focused guide explains how to pull IIMJobs listings for management, finance, consulting and HR roles into a spreadsheet, rather than checking the board manually. Each listing carries details such as posting date, experience range, disclosed salary, locations, skills, and applicant and view counts. A small sample of about 50 results per keyword, covering the last seven days, found that fewer than one in five postings disclosed a salary band. Talent acquisition postings drew a median of 201 applicants, while investment banking postings were concentrated in Mumbai. The author, who built the scraper tool used, describes a no-code workflow on Apify that costs a few dollars per thousand jobs.

Same Injection Sentence Carries Different Risk Depending on Its JSON Field

A prompt-injection scanner called attest classifies JSON fields by their role rather than treating every string the same. When an injection signal appears in a non-result field such as description, name, or source, it is rated critical and labeled with its location. The same sentence inside a result-carrying field like content stays at its base severity, since that is where agents legitimately receive text. The author notes the approach is signature-based and can be evaded by paraphrasing, for example with 'disregard the prior context' phrasing that goes undetected. The project is presented as defence-in-depth rather than a complete safeguard, and its demand is still unproven.
