I have a recommendation to help bring some sanity to this whole AI doomerism situation that is appropriately exploding today. If any reporter can get one of the "true believers" to sit for a real interview (if they can't, that is an important tell), they should use a technique known as the "Five Whys" https://t.co/RqKrn4TNLa. The "five" number is arbitrary, but the point is to drill down into the details and steps required to get to the catastrophic end-point. You can't take down all of humanity without a few intermediate steps. Let's talk through each of those. It's quite a useful exercise.… Related

Author of The 4-Hour Workweek and Tools of Titans, and host of The Tim Ferriss Show podcast.
I get a lot of questions about "marketing," and people usually ask a granular technical question, but I think they usually miss the forest for the trees. Perhaps "What exactly is 'marketing'?" is the question I don't get asked. My answer: "Marketing" is knowing exactly who your reader or customer is, and making a product exactly for them. Kevin Kelly's "1,000 True Fans" is a great read that helps this type of thinking. People should spend 80% of their time on product, and the so-called "marketing" largely takes care of itself later.

Computer science professor who works on fast data processing; co-author of the simdjson parser and a weekly blogger about software performance since 2004.
One very visible effect of AI this summer has been a large influx of bug fixes. In some sense, it is the opposite of AI slop. I manage widely deployed libraries and, in some cases, the number of pull requests has been doubled. In the simdjson library, I merged 92 pull requests in 2024, I am at 134 thus far. In many instances, AI found long standing well hidden bugs. It makes me happy because I dislike bugs. But this puts stress on people packaging and distributing these libraries. Sadly, I have also never received so many pull requests that I have not merged. For simdjson, I received 219 pull… Related

My biggest takeaways from Grok @Bot product lead @RomanUgarte_: 1. Two key early product decisions made Grok Bot the success it has become. First, everything runs in the cloud. This means bots can be kicked off from a phone and run while the user sleeps. Second, each bot has access to its own computer. This allows it to operate on tools that have no API because they can simply use the computer the way a human would. 2. “Unshipping” is a big opportunity in product right now.

You work your ass off to get a lot of money. But what is that money actually for? Money has no intrinsic value—it only matters if you have a clear purpose behind it. Will it get you better friends, a better marriage, or a better relationship with your kids? You better answer that question first. To me, real success isn’t about the money. Success is knowing your nature, finding the best path through that nature, and being able to look back and say, "That was the life I wanted to have."

Even if an AI did exactly what I told it to do, precisely and without error, I would still work hard as an engineer.

And design is ridiculously difficult. You need to decide what you will build and how you will build it. Of course, you can outsource the design to the AI. But that's assuming t… Related

My personal recommend is: try to understand 40% of what is, then try to build it, and continues learning from there. Quoting @ycombinator Harnesses often get dismissed as just scaffolding, just prompt engineering, and not real research. But that couldn't be farther from the truth. The same model weights that score 30% on ARC-AGI score 95% with a better harness. So we gathered a group of researchers and founders working at the frontie… Related

It is fine to repeat your words. In fact, it is fine to repeat words not only “in the same section,” but in the very next sentence. Successful rhetoric is a story of variation—but that does not mean you should vary constantly. Constant variance is simply noise; a distinctive voice is made less, not more distinctive by background static. The goal is to set expectations, then break them. Long sentences are broken by short ones. Latinate terms are broken by Saxon ones. You repeat a cadence, or a figure, or a word—and then you break the pattern you have set. This keeps readers interested. It also… Quoting @tomieinlove There's a soft rule in English prose: you shouldn't repeat the same word in a section.

Nothing matches. Show everything
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
