Amazon has cut the price of the Bose Smart Ultra Dolby Atmos Soundbar to $669, a $330 discount off its $999 list price and the lowest it has been. The soundbar features a nine-driver array, up-firing speakers, ADAPTiQ room calibration, and supports HDMI eARC/ARC, Wi-Fi, Bluetooth, Ethernet, AirPlay 2, Spotify Connect, and Chromecast, with built-in Alexa and Google Assistant support.
A technical blog post examines the common practice of AI agent designers asking large language models to output a numeric confidence or probability score alongside their answers. The author argues there is no sound basis for trusting these numbers, contrasting them with how a human forecaster's confidence is grounded in historical data and a consistent updating process.
Amazon is selling the Bose Smart Ultra Dolby Atmos Soundbar for $679, down from its $999 list price, a $320 discount. The price matches the lowest seen for the product so far this year, according to the report.
When temporary tariff structures were struck down earlier this year, e.l.f. Beauty received roughly $50 million in cost relief and used it to reverse price increases across 80% of its product lineup instead of keeping the extra margin. The following quarter, the company reported net sales up 36% to $479.4 million with profits roughly doubling.
A technical write-up describes RLCD (Reinforcement Learning from Calibrated Decisions) as an evolution of reward modeling, moving from scalar reward scores to pairwise preference models like PPRM, and finally to a schema-conditioned, multiway probability distribution. It explains that Jev implements this RLCD objective by adding typed outputs and parallel inference, effectively turning the reward model itself into the primary decision-making system rather than a hidden scoring layer behind a generator.
A technical blog post examines TypeSafe's new Jev system, a 'System One Model' that converts unstructured input into typed decisions with attached probability scores instead of generating text. The author argues Jev is genuinely useful because it works without requiring training data, unlike a fine-tuned BERT model, but disputes TypeSafe's claim that its RLCD training method produces probabilities that are truly calibrated across any dataset.
Roku TVs offer several picture modes accessible via the remote's star button, including Standard, Movie, Vivid, and Roku Smart Picture, each affecting color saturation, brightness, and processing differently. Users can further adjust brightness, contrast, sharpness, and backlight in the Customize picture menu to fine-tune image quality beyond the preset modes.
A technical essay examines why using large language models directly as classifiers is frustrating despite decent performance, citing problems with calibration, inability to reliably use structured data or context, and limited interpretability of prompt-following behavior. The author suggests reframing the role of LLM outputs entirely rather than treating them as final classification decisions.
The author has rebuilt an AI-generated code comment detector, previously trained on private data with an unstable foundation, using only public data and a more solid architecture. The new tool runs entirely in the browser, processes pasted text locally without sending it to a server, and offers an interactive interface that highlights which text features drive its human-vs-robot judgment.
A hobbyist purchased a Tektronix TDS7104, a 1 GHz, 4-channel oscilloscope from the early 2000s, at a Silicon Valley flea market for $300 after negotiating down from $700. The unit initially powered on and ran fine, but hours later it failed to boot properly, throwing a CMOS battery error at the BIOS screen. The author documents the process of diagnosing and repairing the aging instrument to restore full functionality.
