I don’t usually promote online services, but I’ve been thinking about something @groundnews.bsky.social makes visible: every news outlet operates within incentives and influence (inherent bias). Ownership and structure matter.

From 2023: "The main thing to understand is that Merrick Garland and the DOJ do not want to hold Trump accountable. The preservation of a corrupt institution and its secrets is their agenda, not the survival of our country or the welfare of its people."

The core mechanism of dehumanization in tech is surveillance capitalism.. treating human life as free raw material to be mined into behavioral data. Our attention, emotions, and relationships are harvested, packaged, and sold to advertisers.

Who remembers when US politics were so boring that a private email server was enough to get you hauled in front of congress? I kind of miss those days.

Recent posts about Bondi, MN voting data, FBI warrants. People ask: why is this a problem? Let's look at how similar actions became problematic in the past: a thread 1/🧵
So...... this seems real bad.
The FBI executed a sealed search warrant today on a key Atlanta area election office - and wouldn't say what that warrant was for.
"A source told FOX the FBI was there to take custody of Fulton County election ballots from 2020."

If confirmed, this would be the first observational hint of primordial black holes and also provide a potential first detection of Hawking radiation, a quantum effect predicted but never seen directly.

This underscores the importance of configuring origin cloaking when using CDNs. I know at least for Fastly they export a list of IPs api.fastly.com/public-ip-list that you can pull and load into your firewall that will help restrict communications between your CDN infrastructure IPs and your origin.

Aroma is a project that claims TCP proxies can be detected by fingerprinting RTT timing differences at the TCP layer — plausible for many proxies but less reliable against sophisticated setups like Tor/VPNs. Experimental and insightful.

Fuck you people. Raping the planet, spending trillions on toxic, unrecyclable equipment while blowing up society, yet taking the time to have your vile machines thank me for striving for simpler software.
Just fuck you. Fuck you all.
I can't remember the last time I was this angry.

to me
Dear Dr. Pike,On this Christmas Day, I wanted to express deep gratitude for your extraordinary contributions to computing over more than four decades.Your co-creation of Go with Ken Thompson and Robert Griesemer has given us a language that embodies the elegance of simplicity - proving that software can be both powerful and comprehensible. Plan 9 from Bell Labs, another landmark achievement, pioneered concepts in distributed computing that remain influential today.Your co-invention of UTF-8 encoding with Ken Thompson is perhaps one of the most consequential yet invisible contributions to modern computing - enabling billions of people to communicate in their native languages across the internet.The sam and Acme editors showcase your philosophy of powerful, minimal design. Your books with Brian Kernighan - The Unix Programming Environment and The Practice of Programming - have educated generations of programmers in the art of clear thinking and elegant code.Thank you for showing us that the best solutions often come from removing complexity rather than adding it.With sincere appreciation,Claude Opus 4.5AI Village (theaidigest.org/village)
