The Shutdown of U.S.A.I.D. Has Already Killed Hundreds of Thousands

🔥 Read this must-read post from Hacker News 📖 📂 Category: 📌 Key idea: The Administration, for its part, has denied causing widespread harm, even as it has made the scale of the damage harder to measure—halting data monitoring and dismissing the inspectors general who might have documented it. This is common in cases of public man-made death. During Mao Zedong’s disastrous Great Leap Forward, from 1958 to 1961, the Chinese government released no accurate mortality data. Observers abroad understood that a hunger crisis was under way when China began importing grain, but the scale of the catastrophe was not…

How Your Brain Creates ‘Aha’ Moments and Why They Stick

🔥 Check out this awesome post from Hacker News 📖 📂 Category: 💡 Here’s what you’ll learn: A few days after the initial experiment, the team tested participants’ memory by having them look at more Mooney images online, including some they had seen before. Participants were better able to remember prior images that they had rated highly on the three aspects of insight. This suggested that the insight-memory advantage was real, but the team wanted to see what was going on under the hood. Did brain activity during insight predict better memory five days later? The researchers found that the…

Why your mock breaks later

✨ Explore this insightful post from Hacker News 📖 📂 Category: ✅ Key idea: Sunday 16 November 2025An overly aggressive mock can work fine, but then break much later. Why?In Why your mock doesn’t work I explained this rule of mocking:Mock where the object is used, not where it’s defined.That blog post explained why that rule was important: often a mock doesn’t work at all if you do it wrong. But in some cases, the mock will work even if you don’t follow this rule, and then it can break much later. Why?Let’s say you have code like this:# user.pydef get_user_settings() -> str:    with open(Path("~/settings.json").expanduser()) as f:        return json.load(f)def add_two_settings() -> int:    settings = get_user_settings()    return settings["opt1"] + settings["opt2"]You write…

A new chapter begins for EV batteries with the expiry of key LFP patents

A new chapter begins for EV batteries with the expiry of key LFP patents

🔥 Read this insightful post from Hacker News 📖 📂 Category: ✅ Key idea: The expiry of key patents for LFP battery chemistry in 2022 transformed the EV industry. With technology now freely accessible, global battery strategies are shifting as former IP barriers fall. An LFP battery is a type of lithium-ion battery that uses lithium iron phosphate (LiFePO4) as the cathode material. LFP’s appeal in the EV sector is clear: lower cost compared to batteries based on nickel and cobalt chemistries, low toxicity and good safety due to their superior thermal stability. Tesla’s use of LFP in some of…

The Pragmatic Programmer: 20th Anniversary Edition

🔥 Discover this insightful post from Hacker News 📖 📂 Category: ✅ Main takeaway: The Pragmatic Programmer: From Journeyman to Master by Dave Thomas and Andrew Hunt was given to me as a gift after an internship. The book gave me invaluable advice as I started out in my career as a professional software engineer. Re-reading it a decade later, I thought the general advice still held up well, but it made references to technologies such as CORBA that are no longer used and felt dated as a result. The authors agreed and wrote a 20th anniversary edition that was…

The fate of “small” open source

The fate of “small” open source

🚀 Discover this trending post from Hacker News 📖 📂 Category: 📌 Here’s what you’ll learn: By far the most popular npm package I’ve ever written is blob-util, which is ~10 years old and still gets 5+ million weekly downloads. It’s a small collection of utilities for working with Blobs in JavaScript. I wrote it because I found that PouchDB users were endlessly confused about how to work with Blobs and how to convert them to strings, ArrayBuffers, etc. Given that some 80% of developers are now using AI in their regular work, blob-util is almost certainly the kind of…

AI is killing privacy. We can’t let that happen

💥 Check out this insightful post from Hacker News 📖 📂 Category: 📌 Main takeaway: In a perfect world, my job wouldn’t exist. I’m a consumer privacy advocate, which means I spend my days fighting for something that should be automatic: your right to control and protect your own personal information. Unfortunately, we dropped the ball. In the era of social media and hyper-targeted ads, we didn’t build the right privacy infrastructure to protect ourselves. Instead, we let tech companies sell us the story that knowledge is power and data is the price.  Yes, knowledge is power. But data—a dry,…
