Just a PSA for folks here in the US because tax season is coming up and some of you may be using H&R Block Business 2025. I discovered that the software installs a root CA named "W…

I signed up for Comcast Xfinity using a brand new “hide my email” address and three months later I started receiving phishing emails at that address. (I’ve gotten over half a dozen…

I have a blog hosted on GH Pages generated with Jekyll. I got this email from the researcher: > To Whom It May Concern: > > My name is Tom Harris, and I am a resident of Sacramento…

Yeah it’s 2021 and Chinese manufactured are more reliable and higher quality than anything American made. As an anecdote I build PCBs for a hobby and I’ve purchased PCBs and chips …

Smells fishy. High tech product at a super low price. $1 reservation. “1337 people have reserved.” Creator name is “Stone” Li. Uses some website called “viralmarketing”. My guess i…

Instead of complaining about the quality of the article, I’m thinking about the open question at the end. What would be a higher level abstraction for FPGA development? Is it possi…

Great app but the ability to remap caps lock to Esc on an external iPad keyboard is why I went with Blink shell instead.

The article is garbage so I skimmed the paper. Here's what I gleaned (apologizes for any mistakes). So they created a modified RISC-V architecture and added a tagging infrastructur…

If P=BPP as we suspect, what advantage does this give us?
