And weekly is the right cadence for seeing the bigger picture for news too.

There are legitimate reasons to get help from LLMs when writing, including being an ESL. The comment has substance.

Hear hear. And like many other aspects of accessibility, it will help a huge number of people who may not have any severe issues. e.g. non-native English speakers using LLM-powered edits.

Mea culpa.

Without the proper knowledge or measurement equipment, I observed that the audio would fade out after a 30 cm distance. Combined with running it for mere seconds to test and record a demo, I assumed to be in the clear with the spirit of the regulations. Appreciate the reminder to be responsible with RF.

Highly recommend his Pico-based microcontroller course: https://www.youtube.com/playlist?list=PLDqMkB5cbBA4GisLzRSqw...

The PWM-based modulation is interesting, but as an amateur, I couldn't fully understand it or trust that the radio receiver reliably picks up the duty cycle as amplitude.

> We're not the world police.

That has been the bargain since WWII though. Pax Americana meant the US owned and enforced a global order, in return international trade and finance ran on its platform. Most Americans can't fathom how bad the alternative is to not being the world police.

I'm surprised and impressed that this works. I would've guessed phones have enough RF shielding and low-pass filters in the audio path to prevent this.

New comment by pesfandiar in "Starting a startup at 25, 35, or 45 is not the same decision"

The financial gains from starting a startup have a wildly varied distribution. The analysis won't be very practical if we assume any meaningful exit at any age. Not sure how a "weak exit" is considered the most common outcome.

New comment by pesfandiar in "Ask HN: Is it just me or techno-optimism died in the past few years?"

pesfandiar — Sun, 07 Dec 2025 18:57:30 +0000

The signs of techno-feudalism have always been around in fragments (platform/cloud landlords, rent-seeking, gig work, ...), but the promise of hitting gold, the idea of democratized innovation, and the reliance on mass tech labour fueled the techno-optimism. Now, the heavily power-centralizing nature of AI and the shrinking reliance on tech labour have diminished the optimism.

That might change if geopolitical tensions fragment the global supply chains.

As a parent, I found "The Anxious Generation" by Jonathan Haidt insightful and eye-opening.

It's wrong to assume the owners will share the productivity gains with everyone, especially when reliance on labour will be at its lowest, and the power structure of a data/AI economy is more concentrated than anything we've seen before. IMO, the assumption that some form of basic income or social welfare system will be funded voluntarily is as delusional as thinking communism would work.

Do you mean the bubble in the financial markets, or disillusionment of capital assuming they get to lay off half the employees for the same output?

New comment by pesfandiar in "Ask HN: Anyone switched from software to physical world engineering?"

pesfandiar — Thu, 25 Sep 2025 16:13:42 +0000

For sure. The engineering jobs typically have a lower pay and you'd have to start out as a junior, so higher income won't be a reason for the switch.
