> This post didn't age well – 3 weeks later Substack announced a $100m fundraise at $1.1b valuation.

From the article: Newcomer says Substack is “pitching investors on a round between $50M and $100M that would value it above its roughly $700M last round price.”

Also: And if Substack does manage to raise that $100M they’re looking for now? Things will get worse.

The central problem seems to be that the people who are in a position to benefit from claiming something is fake that's actually real are the same ones you have to trust to determine whether it's fake, since the viewer can't determine that (even if they provide a black-box program that supposedly checks this, you can't know what it really does so the same trust problem exists). Maybe this would be useful for a while in an organization to be sure employees aren't using editing and tools on video.

They do work that way. Lots of studies show gains in muscle mass even with no excercise when people are on steroids. Consider average men who never excercise vs average women who never excercise. The men will have more muscle. That's what testosterone does, among other things.

That's part of why steroids were and sometimes still are used medically for people with cancer and other wasting diseases. It makes them eat more (they're usually strongly appetite inducing) but they also just help develop muscles even if sedentary.

(Of course it would be far more effective to also engage in high intensity resistance training.)

> despite the clear preferences of younger people

But the assertion was not that young people have a 'clear preference' not to have children, it was that they just have a clear preference to engage in a behaviour that, as a side-effect, lowers birth rates.

> we both understand

I'm assuming that you're not doing this intentionally, but by asserting that I "understand" the commenter is trying to 'coerce [me] into having a more positive "positive" birth rate', a notion that I still disagree with, you're suggesting that I'm being intentionally obtuse. Please don't do that.

The same criticism was leveled at social media, mostly Facebook. Then at mobile phones. Before that, it was aimed at television. In between, it was aimed at games.

The big change is that we've solved boredom. More entertainment content is instantly available than anyone can consume. Humanity has solved "timepass". (That term is used mostly in India [1], but is generally applicable.) A sizable fraction of the population walks around looking at their phone. Once AR glasses catch on, that will get worse.

If you're not bored, you can be lonely, but it doesn't matter as much.

It might be that a person with roommates is more likely to be introduced to more people and therefore more likely to find someone to marry, than a person without roommates. No idea if there is any data on that.

My own experience is that when I had roommates they would invite people over or invite me to activities where I'd meet new people with very little effort on my part. Vs when I've lived alone it felt less far less likely to meet new people without more effort.

I still don’t believe this suggests intelligence is inevitable. Case in point there are very few species out of all species that show intelligence. A fraction so small it rounds out to 0% of earths species showing intelligence. Seems if anything the data suggests that intelligence is not a needed adaption for life to proliferate.

Adaption depends on context to find success. We see intelligent life more or less operating on the edge cases of ecological niches, taking us back to prehistorical times for this example when our numbers were fewer until agriculture increases carrying capacity of the land. In all cases intelligent life did not dominate, it exists at the edge of some ecological niche scraping together what few resources an intelligent species can gleam from the environment. Indeed the oceans are not dominated by octopus, the skies not dominated by corvids, and for most of human history our numbers were quite small until agriculture. Even today we don’t dominate the planet, only really the most ideal habitable zones for our species.

Flight is far more widely distributed shared among most birds, bats, some reptiles, and many thousands of insects. And that only worked because everything was just right for it. Temperature and oxygen content happened to select for organism sizes capable of flight in our particular atmosphere and overcoming our gravity with sufficient lifting forces. If any of these variables were changed its possible flight would have never happened on this planet.

To put something into a formula based on its rate of emergence on earth is therefore based on a lot of assumptions about latent variables involved.
Show HN: Repocks – Local RAG from In-Repo Markdown Docs
by boke0 | 2025-08-02 18:42:20+00:00
I built CLI tool "Repocks", a local RAG server that indexes Markdown docs under your project directory and answers questions via MCP Server.

- Uses Ollama (LLM + embeddings) and DuckDB

- No API keys, fully offline

- One server per project (runs via stdio), so no data mixing

- Ideal for replacing bloated instruction files (like CLAUDE.md)

You can install via npm: https://www.npmjs.com/package/repocks

Oh not my joy, back during Covid I must’ve done this dozens of times over the course of a year so I could hang out with my friends. However I’m pretty sure we only got away with it because cops just weren’t looking at all since aside from us, the park was fully empty.

On the whole I would not use the term “reasonable” to describe police. They’re power tripping infants who love to lord authority over people, and to the extent we get away with things it’s because they’re also lazy.

It's difficult to overstate how much better my life has become after starting tirzepatide, consequently losing weight, and steadily increasing exercise as I've gotten lighter. If I were the richest guy in the world, I'd negotiate with Eli Lilly to make tirzepatide (or maybe the forthcoming orforglipron) basically free for anyone who wants it.

If you don't manipulate the visual part, lip movements wouldn't match up to what's said. If you do manipulate it that now has to respect the super special light. I don't think it'd be impossible, but it'd be far harder than a regular deepfake. And even if you succeed (or someone writes good software that can do it) the white house can still point to the original video to show that the two were presumably taken at the same time, so one of them must be fake.

It'd agree that it's a lot of effort for very marginal gain

You may be thinking of butterfly keyboard switches, which aren't what is being discussed here. The Thinkpad "butterfly keyboard" was a design which moved pieces of the keyboard around to make a keyboard wider than the laptop pop out when the laptop was opened. This video has a demonstration:

https://www.youtube.com/watch?v=sVrpRgKS2x4

The purpose of this design was to allow a small laptop, with a small screen, to have a near full-size keyboard. Once larger screens forced laptops to become larger as well, this design was no longer needed.

MidWest metro.

More than half of the office buildings downtown are empty, and the ones that do have something only have a business in a handful of offices on a handful of floors.

Because of that, people started moving away because of lack of nearby jobs.

As people moved away, rents increased in both commercial and residential spaces to cover losses.

Library attendance and checkouts are way down.

Public transportation use is down.

Tax revenue in the city is down, which means less support for public services.

It's fucking awful.

I rode motorcycles most of my life. I stopped during the pandemic and I'm sort of thinking of maybe getting another bike. Trying to balance the fun with the realities of riding.

Anecdotally, I've been to the funeral of a fighter jet pilot years ago who died on a motorcycle after a bus cut him off, in the city. This would be someone at the top 1% of skill, attitude and experience. The reality of riding a motorcycle is that you are completely exposed/unprotected (leather vs. a metal box) and there are many situations you can't predict/control.

I've had a few crashes myself, including a high speed one, possibly some I could have avoided but for whatever reason didn't. People make mistakes, have poor judgement, and can't always be 100%. My worst crash was when someone T-boned me in the city doing an illegal left turn across three lanes. If I had been paying more attention I could have predicted/avoided/seen it but I didn't. I even had my visor open and got the handlebar in my face. I walked/drove away from that one just like all my other crashes with some minor injuries.

I've been looking for that Paradox Photoshop CS2 one for years. Great nostalgic memories.

I've always been in slight awe of these kind of teams/releases. Cracking (mostly) for the raw intellectual challenge and bundling it with demoscene-ish artistic expression - usually a unique UI and obviously a great chiptune. I've always wondered why that behaviour emerged..

This is specifically about long distance running, where basically no animal can keep up.

A key hunan advantage was persistence hunting - track and run after a deer (or similar) prey. Tgey can burst outrun the human, burt hemshe keeps on running, eventually, often after double-digit kilometers, the human can just trot up to the exhausted nimal and kill it. That's what the tendons and evaporative cooling do.

There's a famous Uktramarathon race, iirc, the Western States 100, 100 miles in the Sierra mountains that was a horse race, until some people started running without the horse, and winning.

This. It helps to tell it to plan and to then interrogate it about that plan, change it to specification etc. Think of it as a refinement session before a pairing session. The results are considerably better if you do it this way. I've written kubernetes operators, flask applications, Kivy applications, and a transparent ssh proxy with Claude in the last two months, all outside of work.

It also helps to tell it to write tests first: I lean towards integration tests for most things but it is decent at writing good unit tests etc too. Obviously, review is paramount if TDD is going to work.

This would be a really cool idea for municipal swimming pools or large residential developments. It blows my mind that people pay to heat up all these data centers and then pay again to get rid of the heat. Data centers could rent space by paying in kWh of heat.

I would set something like this up in my house if there was some kind of decentralized processing company I could register with.

It doesn't help that a lot of skeptics are also dishonest. A few days ago someone here tried to claim that inserting verbose debug logging, something Claude Code would be very good at, is "actually programming" and it's important work for humans to do.

No, Claude can create logs all across my codebase with much better formatting far faster than I can, so I can focus on actual problem solving. It's frustrating, but par for the course for this forum.

Edit: Dishonest isn't correct, I should have said I just disagree with their statements. I do apologize.

"Why take the risk?"

You end up on video for drunkenness with police, and assuming they don't shoot you or beat the fuck out of you, the video still ends up on the internet.

The next day at work, you quickly get called in to talk to your manager and HR, and now you have to find a new job.

Time to find a new job! And in this market? Not worth the risk. Now companies are searching for New Hires on social media, and guess what? Your video pops up.

This is why people stay at home. Nobody trusts one another, or most of the institutions.

Your second paragraph sounds like you're describing Avalonia. Avalonia has AOT, compile-time binding errors and cross-platform support. Maybe there have been some updates since you last tried it? I'm not very familiar with Avalonia or WPF though so maybe there's more to it than that.

I've been using Claude code 12-16 hours a day since I first got it running two weeks ago. Here's the tips I've discovered:

1. Immediately change to sonnet (the cli defaults to opus for max users). I tested coding with opus extensively and it never matches the quality of sonnet.

2. Compacting often ends progress - it's difficult to get back to the same quality of code after compacting.

3. First prompt is very important and sets the vibe. If your instance of Claude seems hesitant, doubtful, sometimes even rude, it's always better to end the session and start again.

4. There are phrases that make it more effective. Try, "I'm so sorry if this is a bad suggestion, but I want to implement x and y." For whatever reason it makes Claude more eager to help.

5. Monolithic with docker orchestration: I essentially 10x'd when I started letting Claude itself manage docker containers, check their logs for errors, rm them, rebuild them, etc. Now I can get an entirely new service online in a docker container, from zero to operational, in one Claude prompt.

Also punch the guy that allows Google Maps navigation to flip back to a route that's been specifically rejected.

Earlier this week Google prompted me with "your route may be affected by tsunami warning". Indeed, so I chose the longer, inland route rather than the coast roads.

15 minutes later I realise it's rerouted me "due to traffic conditions" -- obviously the coast road isn't as busy!

(This has happened many times before, but this was the first time I had a safety reason not to take the faster route.)

They aren’t as different as you might expect. They both use nucleic acids and polymerase activity. That is probably what gp means by life having one form here and it is right, all life uses genetic material like this.

Virus is only considered not “alive” because it uses a host for its life cycle but that is more or less an opportunistic adaption like we see all over life in different situations, even humans in terms of some of the amino acids that must be sourced from the environment: why make everything you need yourself when you can instead steal that thing from your neighbor?

I love the fantastic designs and form factors popping up in mini-EV truck/SUV space. My worry is for the business feasibility for these. Why isn’t Tesla making these? They have the supply chain and expertise to easily pull it off and they’d be such a big hit. People switching to them for light cargo would be a REAL contribution in cutting use of carbon.

I can think of one possibility. At Tesla’s scale, production becomes feasible only if they can produce X million units. This is because setting up production tooling, supply chain channels, and other associated costs is prohibitively expensive. Additionally, the demand for these vehicles will be relatively low until influential YouTubers in the construction, farming, and rural sectors become advocates and start promoting them.

In my opinion, electric vehicles (EVs) are perfectly suited for this task. They are ideal for transporting heavy items between nearby destinations, such as moving Home Depot supplies to a construction site or Costco products to a restaurant or store. A range of even 200 miles is practical for this use-case and keeps the cost low (MT1 is a beast by my standard).

For clarification, I am all for more competition. But I am also selfish and I really want this segment to become wildly successful . In any case, I really and truly hope they can make the business case work and be profitable/sustainable.

The people successfully using Claude Code for big projects aren’t letting it get to the point where they don’t understand what it wrote.

The best results come from working iteratively with it. I reject about 1/3 of edits to request some changes or a change of direction.

If you just try to have it jam on code until the end result appears to work then you will be disappointed. But that’s operator error.

> I think it's amazing what has happened in the open-source space with Rust-based UI frameworks (iced, egui, slint) and COSMIC

Do you mean it is amazing how poor is an experience and how many features, widgets and controls they lack when compared with something like FPC/Lazarus and Qt?

The article was published in 2016, and the authors extrapolated from 7 data points (!) over about 7 years of progress in the world record. This is obviously insufficient to project 30 years into the future.

https://pubmed.ncbi.nlm.nih.gov/27446911/#&gid=article-figur...

That record progressed

2008 18.58 2015 15.71

2.87 seconds over 7 years. https://en.wikipedia.org/wiki/Kenichi_Ito_(athlete)

If we check in on more recent progress since then, we find the current record is 15.66 set in 2022. https://web.archive.org/web/20241222175947/https://www.guinn...

Another 7 years, for an improvement of 0.05 seconds, or about 850 years of linear improvement to reach Bolt's 9.58 seconds.

I'm not willing to preorder an unproven brand, but I am excited about this. I'm a Toyota RAV4 owner, and I'd like something (much) more fuel efficient, or a fairly affordable EV, but I don't want to lose moderate hauling capacity for equipment, tools, parts for home, etc. I would seriously consider a very small/compact car but I do need to fit a car seat and I do occasionally move things.

I hope this makes it to market because if I was buying a car today, and this was available today, I'd pick this.

Pretty much the worst thing you can do exercising is an ACL tear or an Achilles tendon rupture. Both of these are absolutely awful injuries to pick up (whoever designed the human body really phoned it in at the knee joint IMO). Both are usually solved with surgery, and will massively impact your life for 9-12 months. But the real fix to those injuries is to get back exercising again. If Tom Brady can play NFL football after an ACL tear and surgery, you can probably go back running with the right advice.

The only way to avoid injury is to not use your body at all but your muscles will atrophy and you’ll end up injured _anyway_ that way.

This especially. I've never worked at a place that didn't skimp on tests or tech debt due to limited resources. Now you can get a decent test suite just from saying you want it.

On one hand I agree. It makes me sad but I'm skeptical they are going to make it.

On the other hand, electric cars seem to be relatively "easy" to build. Sure, Fisker went bankrupt, but Rivian seems to do sort of fine. Xiaomi even managed to build a car, and I actually saw one of them by chance charging next to me today.

Seems to me like a lot more newcomers succeed in getting cars built, than was and is the case with ICE cars.

Gas is at worst 6 bucks a gallon, which gets you 30 miles on a bad car. That’s enough for like 5 hikes; if you can’t afford a single dollar split across all your friends for multiple hours of entertainment and exercise then I do concede that you are in a bad spot; but I think most of us are not quite so destitute. (Also, my friends and I do the same hikes all the time.)

Pickleball courts do not cost money, they are freely provided by the state. I go to free pickleball courts every week in SF, and I bike there for free. You can buy 4 paddles for $20 at sports basement and get literally hundreds if not thousands of hours of entertainment just on that.

I dunno, I don’t have a lot of sympathy for this perspective. Almost everything I do with friends isn’t particularly expensive - if you can’t find cheap things to do you just aren’t even looking.

I am glad to see EV companies doing something different, aesthetically. In this particular case I do not like it -- at all -- but I much prefer a high-variance aesthetic distribution to the genetic every-car-looks-the-same world we have now, sans a tiny few exceptions.

The side compartment under the bed / in front of the rear wheel is pretty cool too.
