“You should have used a 555” has become a bit of a meme around these parts lately, and for good reason. There seems to be little that these ubiquitous chips …read more Continue reading Should Have Used a Vacuum Tube 555
Younger readers may not recall the days when every mall had a music store — not the kind where tapes and LPs were sold, but the kind where you could buy instruments. These places inevitably had an employee belting out …read more
Join us on Wednesday, December 9th at noon Pacific for the Vacuum Tube Logic Hack Chat with David Lovett!
For most of us, circuits based on vacuum tubes are remnants of a technological history that is rapidly fading from our collective memory. To be sure, there are still applications for …read more
You’d think that the 8086 microprocessor, a 40-year-old chip with a mere 29,000 transistors on board that kicked off the 16-bit PC revolution, would have no more tales left to tell. But as [Ken Shirriff] discovered, reverse engineering the chip from die photos reveals some hidden depths.
The focus of …read more
A host of unpatched security bugs that allow BIAS attacks affects Bluetooth chips from Apple, Intel, Qualcomm, Samsung and others. Continue reading Bluetooth Bugs Allow Impersonation Attacks on Legions of Devices
A tool from the White House invites those who suspect political bias in social media censorship to “share their story with President Trump.” Continue reading Trump seeks tales of social media bias – and your phone number
IBM has launched a software service that scans AI systems as they work in order to detect bias and provide explanations for the automated decisions being made — a degree of transparency that may be necessary for compliance purposes not just a company’s own due diligence. The new trust and transparency system runs on the […] Continue reading IBM launches cloud tool to detect AI bias and explain automated decisions
Clorama Dorvilias wants to remove shame and guilt from diversity and inclusion training. Continue reading This VR Founder Wants to Gamify Empathy to Reduce Racial Bias
Do you need a bias tee? If you want to put a DC voltage on top of an RF signal, chances are that you do. But what exactly are bias tees, and how do they work?
If that’s your question, [W2AEW] has an answer for you with this informative video on the basics of bias tees. A bias tee allows a DC bias to be laid over an RF signal, and while that sounds like a simple job, theory and practice often deviate in the RF world. The simplest bias tee would have a capacitor in series with the RF …read more
It’s thought to be the first in the country to push for open sourcing of the algorithms used by courts, police and city agencies Continue reading New York to crack open its code, looking for bias
