Doing a more extensive SI/PI workup on the switch line card in preparation for a) a blog update on the switch project and b) getting all my I's dotted and T's crossed before spending a lot of money stuffing three more boards and ordering the logic board.
Here's the 2.5V rail, putting out a bit over 2A at 2.5V. Ripple is dominated by ~300 kHz switching noise plus some harmonics of the 125 MHz PHY symbol rate (which makes sense this rail is driving the PHY PAM5 transceivers a…

ngscopeclient screenshot showing FFT and time domain views of a nominally 2.5V power rail that's actually closer to 2.48. There's some very slight switching spikes and the FFT shows harmonics of the PHY clock but they're at < -70 dBm

Join Kevin Liang at this year's Berlin Buzzwords, where he will discuss how Apache Solr/Lucene builds dense vector indexes and talk about how he and his team optimised their dense vector setup, sharing the challenges they faced and the best practices they learned along the way.

Session title: Performance Tuning Apache Solr for Dense Vectors

Performance Tuning Apache Solr for Dense Vectors
With the recent boom in AI, many organizations are in the process of building semantic search stacks from scratch powered by Apache Solr and dense vectors. What many quickly learn when dealing with dense vectors is just how heavy the compute requirements are for vector search compared with lexical search. If not well-tuned, vector search query latency can quickly skyrocket, even with an otherwise reasonably sized dataset. We experienced this pain firsthand when we started vectorizing a 100M+ do…

A few months ago I got a Ting through State Farm Insurance. It monitor's my home's electrical system for micro-arcs and precursor events of electrical fires, and is supposed to alert me (and Ting) if it detects anything dangerous.
You can check the status with a phone app, and they also send weekly reports by email.

A small device (approximately 4" by 2") plugged into an electrical outlet. A small green light appears at the bottom under the label "ting".
A screenshot of the ting phone app showing "No Hazards Detected." The current voltage is 121.21 V with a range of 115.3 V to 123.1 V. It also says the closest outage is 122 miles away in Omaha.

An #infosec drama, in two screenshots.

The image is a screenshot of a Twitter post by a user named Quackity, featuring a promotional tweet about a product called DABABEL. The tweet reads: "INTRODUCING DABABEL. THE UNIVERSAL REAL TIME TEXT AND VOICE TRANSLATION TOOL. SPEAK ANY LANGUAGE, WITH ANYBODY, ANYWHERE. AVAILABLE RIGHT NOW." Below the text, there is an image of two men sitting on stools, with one holding a smartphone. The man on the right is wearing a black t-shirt with the text "CAMPO REAL SOCCER" on it. The background is wh…
The image displays a mobile phone screen showing a subscription plan selection interface. The background is black, and the text is primarily white with some red and blue accents. At the top, the time is 7:04, and the battery is at 33%, with 5G connectivity indicated. The interface features several subscription plans: Pro Plan: Highlighted as "Popular," priced at $17.99 weekly, offering 10,000 credits, suitable for regular travelers and those who work, learn, and create across borders. …
