If you know me, you know my line: LLMs lie. A lot.

In 2025, Columbia's Tow Center proved AI search engines botch citations.

I re-ran their test in 2026: 800 answers, and I clicked every link. About 70% wrong, and half the links broken or fake.

My addition: a checkpoint that clicks every link before an answer reaches you, checks the quote is on the page, the site, the date. Fabricated links reaching the reader fell to zero. Wrong answers fell from about 7 in 10 to about 1 in 8.

The engines lie just as much; the lies just can't get through.

The receipts, case by case: https://t.co/i2ZQLyjph1

I ran this 800x across 4 AI search engines on 200 real news excerpts.

Wrong ~7 in 10. Over half the cited links broken, dead, or not the source.

The fix isn't a smarter model. It's refusing to take its word for it.

An AI search engine told me a story came from the LA Times. Gave me the link: https://t.co/aVk7ynecPV

It doesn't exist. The LA Times never ran it. Real source: Entertainment Weekly.

It invented a source, borrowed a real paper's name, and faked a URL to make it checkable.

[Dr. Larry Gray @LarryGray]

The fix isn't a better employee. It's a checkpoint: nothing's marked done until something independent checks it against what was ordered.

I ran it on AI citations. Alone, engines were wrong 7 in 10. Through the checkpoint, 0 fabrications reached anyone.

Ordered dinner on the Sonic app. It said "delivered." Half of it wasn't in the bag.

Nobody lied. Every step reported success. The food still wasn't there.

That's the exact problem I just spent a month measuring in AI. 🧵

🐍💼 Did you know in Python, functions are like VIPs at a concert? 🎤🌟 They're called first-class functions! Why? Because in Python, functions get the red-carpet treatment.

👉 Here's what makes them 'first-class':

You can pass them around like party invites 💌 - assign them to variables, or pass them as arguments to other functions.
They can return from other functions like a boomerang comes back to you
You can modify them on the fly, just like adding a filter to your favorite selfie
* Example Time: Let's say we have a function print_greeting that says "Hello!". We can pass this function to another function greet_twice to double the fun!

def print_greeting():
print("Hello!")

def greet_twice(func):
func()
func()

greet_twice(print_greeting)

Output:
Hello!
Hello!

This flexibility makes Python super versatile. It's like having a Swiss Army Knife in your toolkit!

Next time you code in Python, remember - functions are not just lines of code, they're the stars of the show!

🌐 "Exploring Dual Thread Pools in Python for Optimal Performance" by Itamar Turner-Trauring 🚀

🤔 Ever wondered why you need different thread pools for efficient data processing in Python? Let's dive in! 🐍

1️⃣ CPU-bound tasks: Maximize your CPU! If you have 8 cores, use 8 threads to fully utilize them. More than that? You might face slowdowns due to context switching. 🖥️

2️⃣ Network-bound tasks: Here, CPU cores aren't the focus. It's all about handling multiple network operations concurrently. Async loops like asyncio work well, but sometimes threads are needed. Think requests to a server! 🌍

🔁 Mixing CPU and Network-bound tasks? Don't stick to just one thread pool. Have one for CPU tasks (sized by core number) and another for network tasks (sized by concurrency level). This approach prevents resource limit hits and ensures efficiency. 🔄

🧐 Remember, each application has unique needs. Use these insights as a starting point for optimizing your Python data processing jobs. 💡

Happy coding! 👨‍💻
