Most RESTful APIs aren't really RESTful | Hacker News

"REST" is our industry's most successful collective delusion: everyone knows it's wrong, everyone knows we're using it wrong, and somehow that works better than being right.

"It is kind of, in a way, trying to create a second class of U.S. citizens" - for many of us who immigrated here and became citizens, the message is clear.

Small businesses are the backbone of this city! We should do more to make sure that the many great small businesses we have in San Francisco are supported. Let’s make sure that they remain in our community. Thank you Vas Kiniris, for speaking with my team.

AOC: "On this point of tax on tips, as one of the only people in this body who has lived off of tips, I want to tell you a little bit about the scam ... the cap on that is $25,000 while you're jacking up taxes on people who make less than $50,000 across the US ... while kicking them off the ACA."

I worked at Planned Parenthood.

They diagnose cancers while still treatable. They help women decide what birth control works for them. They help those working through mental health challenges.
 
Defunding them just harms people who already struggle to find places to get care.

The piece of code I am the most proud of is called Dupliclef. I wrote it for my dad to be able to save his USB keys and hard-drives. He is old school, but he religiously preserves his data and emails locally by cliquing on the small icon in his Dock. The script then detects the hard drives and keys.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

The same people who tell you that LLMs can reason and manipulate facts will tell you that one cannot prove that a program is correct.

Model Once, Represent Everywhere: UDA (Unified Data Architecture) at Netflix Introducing UDA, the knowledge-graph-based architecture that translates conceptual domain models into consistent schemas and data…

This post introduces the foundations of UDA (Unified Data Architecture) as a knowledge graph, connecting domain models to data containers through mappings, and grounded in an in-house metamodel, or model of models, called Upper.

We have this super cool new data architecture in Netflix Content and wanted to share it today but we had a technical problem, so the article will only be shared on the Netflix Engineering Blog tomorrow. I hope.🤞

I will be damned if I allow a bunch of Confederate-waving January 6th apologists give the American people a lecture on flag waving.

There is ZERO reason to enter an argument about patriotism with people who still worship traitors to America 150+ years later.

They. Are. Breaking. The. Law.

Many graph-shaped data problems should be solved using a knowledge graph approach, not a graph db. But graph db vendors sure like to conflate the two.

The top 1% makes about a million dollars a year, probably without working at all — just passive income off assets.

An extra 79k is not even noticeable for them. It’s less than what they pay in fees to asset managers.

But $79k would be life changing to anyone in the bottom 80%.

What DOGE gets wrong about tech and government Lessons learned by civic tech, forgotten by DOGE

New, from me:
The DOGE project was sold as tech disruptors who would revolutionize government. To try to understand why DOGE has failed, I point to lessons that other technologists who worked in government learned, but DOGE ignored. 🧵

This is what oligarchy is about.

While planning massive cuts to Medicaid, the Republicans are proposing to provide another $235 billion in tax breaks to the top 0.2% of households through an increase in the estate tax exemption.

The very rich get richer. The poor lose health care. Outrageous.

THE most important political issue facing us now is our corrupt campaign finance system & Citizens United.

As long as Musk, AIPAC & crypto money can buy politicians, we’re not living in a democracy.

We must end billionaire control of our politics and publicly fund elections.

A reminder that if the government can send migrants to a prison camp without any due process, it can send U.S. citizens there, too. I know because this happened to me and my family in 1942.

The American Age Is Over Emergency Triad: The United States commits imperial suicide.

“Whatever the reason was, it exposed half of the electorate—the 77 million people who voted for Trump—as either fundamentally unserious, decadent, or weak.

And no empire can survive the degeneration of its people.”
