> But being at a key canal junction doesn't mean much today, since modern railroads and steamships rendered the canals obsolete a century-ish ago.

That is true for the English narrow channels which are way too narrow to support any kind of large vessel, but not true in general - the Mittellandkanal in Germany for example still sees a huge amount of traffic and there’s regular infrastructure investment going on into the canal network in many places. One example is the new boat lift in Niederfinow which is not as architecturally beautiful as the Falkirk wheel, but lifts entire river barges.

For context, I was born/raised SF Bay Area. Moved to Plumas County (north of Truckee) in 2017 for about 8 years. Didn't mind the snow - have a tacoma trd off road. The electric coop was amazeballs even when PGE tried to screw with them. I've since moved. I like rural - but the wild fires and trumptopia kinda soured me.

I live on an island now with a driveway that has 15-20 degree slope. It snows rarely, but garage is insulated and I need to get a heater near the water pipes. It snowed the one day I had to get to the ferry at 650am for jury duty. I'm glad I had the TRD - it wasn't much but waking up to - doo-dee-doo - drive to ferry and unexpected 2" of snow...causes some anxeity.

If you are using claude, in your project's `.claude/settings.json` you can add something like:

```

"hooks": {
"PostToolUse": [
{
"matcher": "Edit|Write",
"hooks": [
{
"type": "command",
"command": "mix format ${file} 2>/dev/null || true"
}
]
}
],
"TaskCompleted": [
{
"matcher": "",
"hooks": [
{
"type": "prompt",
"prompt": "reminder: run mix test if implementation is complete"
}
]
}
],
"Stop": [
{
"hooks": [
{
"type": "prompt",
"prompt": "Check if all tasks are complete. If not, respond with {\"ok\": false, \"reason\": \"what remains to be done\"}."
}
]
}
]
},

```

Just update it to iterate over your file. It should be a little easier to manage than git hooks and can hammer in testing.

A lot of things that require both art and meeting constraints involve mindfulness, programming being one of them.

People used to talk about "getting into the zone" or "being in the flow" and how open offices disrupt that ability to focus or concentrate.

Now the only flow is management of agentic AI which I imagine is hard for people to get into the same mindfulness state.

> Advertisers do not have access to your chats, chat history, memories, or personal details.

...but thanks to the method OpenAI are using of showing ads based on conversation topics, they do know that user <a> was talking to ChatGPT about topic <x> on one day, topic <y> on another, and topic <z> on another day.

That's still a form of chat history, even if it's vague.

I think you’re missing my point. Even if they were using “real” thread then it then Erlang’s messaging semantics would remain largely unchanged.

Also, it’s not the same thing as async nodejs. Node.js is a fully cooperative system, something CPU intensive can hog the thread and starve the other tasks. Erlang processes are preemptive; every process gets N reductions and then it is parked and the next process can make progress. They’re closer to OS processes than goroutines.

A few weeks ago, I was reviewing the architecture of a fast-growing startup.
Clean services. Solid infra.

Then, I asked a simple question:
“Can you explain exactly how this invoice was computed?”

Silence.

Not because the team wasn’t capable but because billing had evolved into something no one fully owned.

That’s when I realized:
You can tell how mature a company is by looking at its billing system!!

In the early stage, billing is simple. A few plans, maybe some usage tracking, and manual adjustments when needed. Speed wins over structure.

But growth changes the game completely!

Enterprise contracts creep in. Custom discounts stack up. Usage spikes mid-cycle. Credits roll over. Finance starts asking for historical accuracy. Sales wants flexibility. Customers want explanations.

Suddenly billing isn’t a payment problem anymore. It’s a system-of-record problem.

Mature companies can:
- Reproduce past invoices confidently
- Handle upgrades without ambiguity
- Explain every charge
- Close the month without engineering scrambling

Billing complexity doesn’t arrive in one big wave. It accumulates quietly, one exception at a time.

And how you handle that accumulation says more about your operational maturity than any tech stack ever will. Period.

If your friends dumped $20K into paying off those loans they’d be a lot closer to paid off or maybe paid off completely, though. And that’s on a newer, lower mileage car.

I’m all for maintaining vehicles and keeping them on the road, but I don’t think you’re in a place to criticize your friends with $1K car payments after putting almost 2 years worth of those payments into a car that’s over a decade old.

Context from the CDC guidance from August 2025 (https://www.cdc.gov/mmwr/volumes/74/wr/mm7432a2.htm)

"Except for vaccination for adults aged ≥65 years, ACIP makes no preferential recommendation for a specific vaccine when more than one licensed and recommended vaccine is available. Among adults aged ≥65 years any one of the following higher dose or adjuvanted influenza vaccines is preferentially recommended: HD-IIV3, RIV3, or aIIV3. If none of these three vaccines is available at an opportunity for vaccine administration, any other available age-appropriate influenza vaccine should be used (4,5)"

There's a time and a place for certain tools.

Sometimes I like playing chess at the park with strangers or friends. Sometimes I like playing chess online with friends in another country.

Sometimes I like to play games online with my siblings. Sometimes I like to invite people over to play video games with me on the couch.

Sometimes I wanna watch a movie in the theater. Sometimes I wanna fire up Netflix and watch that same movie, but on my couch.

Sometimes I wanna vibe code an entire app in a weekend. Sometimes I wanna play code golf to solve a puzzle, where LLM usage defeats the purpose.

None of these are being replaced in my life despite having more "advanced" options. If anything, I get to enjoy things more because I have more options and ways to enjoy them.

Same here! American-made EVs ask for an incredibly heavy price tag and don’t deliver on the reliability of ICE or Hybrid cars a third of their price. It’s the primary thing stopping me from getting one as my next vehicle.

I’m trying to shop around to replace my wife’s aging crossover and I really can’t find anything more attractive than a Prius or another Kia Soul. If we could get electric cars from the CN market it’d be a no-brainer!

So humans can get pen and paper and sleep and rest, but LLMs can't get files and context resets?

ive the LLM the ability to use a tool that looks up instructions and records instructions from/to files, instead of holding it in context window, and to actively manage its context (write a new context and start fresh), and I think you would find the LLM could probably do it about as reliable as a human?

Context is basically "short term memory". Why do you set the bar higher for LLMs than for humans?

> Essentially the models are given a set of conflicting constraints with some relative importance (ethics>KPIs), a pressure to follow the latter and not the former, and then models are observed at how good they follow the instructions to prioritize based on importance.

> At the same time it is important to keep in mind that it anthropomorphizes the models that technically don't interpret the ethical constraints the same was as this is assumed by most readers.

It does not really matter, though. What matters is the conflict resolution.

The "constraints of some relative importance" or "constraints and instructions" might as well be the system and user prompts. Or any of the "prompt engineering" ways to harden prompts against prompt injection.

Such research tells people right in the face that not only prompt injection is some viable theoretical scenario, but puts some number on the exploitability. With the current numbers I am keeping prompts nine locks away from any untrusted input.

I have walked across it on the John Muir Way which is highly recommended. I actually didn't really remember what Hadrian's wall was. We always learnt it was to "keep out the Scots", but in fact it represented the Northernmost border of the Roman empire. I had no idea about the Antonine wall, nor that they got that far north.

That's a really interesting approach, SamTinnerholm! Giving away risk-free arbitrage opportunities is a unique way to attract and engage users. I'm curious, how do you ensure the security and privacy of the data involved in these transactions? Also, have you considered any specific measures to prevent abuse or misuse of these opportunities? It would be great to hear more about the technical challenges you faced and how you overcame them.

If it's icy there's no difference at all. The only tyres that do anything on ice are the ones with spikes or chains.

If it's snowy a good modern all weather tyre can hold its own, but will brake a few feet later than a good winter tyre.

In all other conditions a good all weather is a lot better than winter tyres, and pretty close to a good summer tyre.

I believe its similar to PayNow Singapore, UPI India, PromptPay Thailand etc where you register your phone number with your bank app, you can send money to those mobile who are on the same network using your bank app, or use your bank's app to scan a QR when making payment to a vendor. The QR code is actually the vendor's number. There are now cross border link, for example I can send money to someone in India using just his mobile number on UPI.

Great question - we keep memory management intentionally simple.

1. There’s no manual memory management exposed at the language level (no pointers, no allocation APIs). I intend to keep it this way as long as possible.

2. Containers (list[T], dictionary[K,V]) compile directly to C++ STL types (std::vector, std::unordered_map).

3. Values follow a strict rule: primitives pass by value, containers pass by read-only reference. This prevents accidental aliasing/mutation across scopes and keeps ownership implicit but predictable.

Anything created in a scope is destroyed when that scope ends (standard C++ RAII). So in practice, memory management in Rox is C++ lifetime semantics underneath, but with a stricter surface language to reduce accidental complexity.

Thank you! And I agree that it's technically not that impressive.
Posting it here was very special for me. First of all, I got tons of valuable feedback and questions. It's also the first step in figuring out how big a role this project will play in my life. I will run it regardless of how many people decide to support it through memberships, however, I want to carve out as much time for it as possible.
It's a commitment to something that I've been dreaming about for quite a while now, that's what makes it exciting for me.
On top of that, I built a website tool that my friends and I actually enjoy to use.

I agree. Although, looking at these assumptions, subjectively I think that all four of them are in question, and as time passes, their eventual long-term failure seems increasingly likely. Even if one of these four pillars persists, I would expect an overall worsening by default. If democratic rule persists in places, the most powerful would occupy places where it does not exist, or create fully private states, still wielding enormous power over democratic states through wealth and military might. If violent rebellion is technically possible, a middle ground will be carefully calculated where the lower classes are kept on life support with the minimum amount of resources required to dissuade unrest. If the trillionaires of tomorrow suddenly start caring about other people, they could employ second-order measures to effectively reduce the population, thereby safeguarding themselves - massively constraining or removing the supply of food, water, medicine, any vital technology that would be only available to them. I don't see how an economic crisis would prevent automated enforcement, it may only delay it a bit.

Hope is kind of in short supply nowadays. Even if your hypothesis of absolute-automation doesn't happen within our lifetimes, things seem to be guaranteed to get worse for people like us. If it does happen... we'll likely never reap any real rewards from it, barring a complete restructuring of our whole society to an extent that has never happened and likely would never be allowed to happen.

The knowledge graph is well done. I think what's missing from all coworking apps is the UX.

Prompting is a very specialized skill, average users just don't know what to ask for to get the most out of the LLMs.

Ideally the UX should organize and surface information to the user that is important automatically, without needing to be prompted.

These things also on my mind recently. I'm a freelancer, providing design-development services, and trying to understand as things changing rapidly.

I don't think even the tools are advancing, allowing us to build in a new way, not everyone will be able to develop production ready products. Or good looking ones. So there will be always in need for people know how to orchestrate the new workflows with good taste and years of experience.

Underrated comment.

Everyone commented on the battery life for my model 3 in winter (which is annoying but not a huge deal). The problems with the bushings, the easily cracked (2500$) roof glass, and the lack of spare parts (not as bad as Rivian) were drowned out.

Love the car, but wouldn't have bought it for the price I paid (used) if I had known.

The R2 looks great but like you said, never buy a first year model.

If you don't want to listen to the whole 3 hours, here's a summary based on the video transcript:

https://chatgpt.com/share/698c1dc4-3794-8013-ba21-2f05c2b3bd...

I didn't listen to the whole thing because it's 3 hours. I would listen to it if it'd be ~30 minutes, even though I'm a bit of a Feynman fanboy, so I'm not exactly pleased by it — but, as a physicist, we have to keep an open mind :)

Based on the summary:

1. Fair points overall.

2. Of course it's embellished! I remember reading the part in Surely You're Joking when he's asked to examine some architectural blueprints, and he doesn't, and then at the meeting he randomly points to some ducts, and gets lucky because there is some major problem there. I remember when I read that 20 years ago, it felt a bit made up.

3. Of course a lot of Feynman books are not written by him! This is kindof obvious though, you go to the bookstore, there are tons of Feynman books, most were published after he died.

4. The point on Maxwell: when I learned EM, it was said that Maxwell got the credit, but a lot of that knowledge, equations were already in the air. If not Maxwell, somebody else would have written them down in a unified way. Same was said for Special Relativity.

5. The point about "Feynman bro", I don't get it. I'm a physicist (working outside the field), I'm a Feynman fanboy (or at least used to be), have a lot of Feynman/related books, and I'm definitely not a "Feynman bro". Also, I've never met anyone I would describe as a "Feynman bro". In general, I've never experienced any macho behaviour among physicists [in Eastern Europe], it's a very different crowd/vibe.

6. Lastly, I feel like this video is doing exactly what its complaining about: monetizing Feynman, using him to get views & attention.

I think you also might be overestimating what the average ICE owner has to take care of.

Most Americans don’t keep a car long enough to even pay it off - they’re in an endless loop of trade-ins, meaning that most non-accident damage is covered by warranty.

I’ve had my current ICE car for just over 5 years now and finally paid my first out of pocket repair cost: $40 for a new washable air filter. Other than that, my expenditures have been tires and a couple hundred bucks in oil changes that I didn’t want to do myself.

> the carplay experience fights with the car OS constantly and is an awful incoherent experience.

It seems to me like fixing this is the appropriate path forward. There are things that the car OS is better at (like you mention), but no car OS is ever going to support the various media apps I have on my phone that are automatically supported by Android/Android Auto media controls, and bluetooth playback is an even worse experience than cludging together the car OS + android auto media in one UI.

They’ll give you a small handful of examples, of which a number occurred in the UK (famously not a member of the EU), most of which were actually arrests for incitement, and of the remainder the majority were thrown out before ever going to trial, or subsequently on appeal.

Very few of the cases they present will have involved citizens being murdered in the streets by the government for exercising their absolute right to free speech.

You’re right usually (about not needing blizzaks) but there’s important nuance here. There are warm all season (with usual M+S stamped on, this just means tread pattern, nothing about compound) and winter all-season with a compatible compound for cold conditions. The industry created a logo for the tires some years back it’s like 3 peak mountain snowflake or something. This ensures the compound is soft enough to keep gripping in freezing temperatures. It’s required in some jurisdictions (Quebec I think and maybe some lake effect zones)

Honestly, I keep an eye on them because we are a core market for their product.. We run a bunch of K8s clusters, and Postgres databases. We currently use cloud, but if someone bought us up, and demanded we stop all cloud, we could move to something like this in a fairly short time, with limited changes. I wouldn't have to deal with Dell, plus VMWare, plus a SAN company plus a networking company, and hope they all work work together nicely.

I could get a spot in a colo, drop 2 fibers assigned to a few subnets, and be up and replicating our databases in a day or two. We have no need for GPU right now, but do need to often switch DB's to add cpu, ram, etc. Honestly, it would pay off in a year to 18 months, depending on the rumored prices, and colo costs.
Show HN: Baby Book Tracker – Track reading to your baby
by AlbertoM92 | 2026-02-11 06:56:20+00:00
I'm a new dad and started reading to my son from birth. I got into the 1000 books by 5 years challenge and wanted a simple way to track what I read to him. Existing apps felt too dated and clunky, so I built my own.

Built this to solve my own problem:
- Quick logging (date, book, reader, language)
- Scan or add your own book manually
- Simple stats on reading streaks and frequency
- Works for multiple kids and multilingual families

iOS only for now (built with React Native). Sign up on the site if you want an Android version: https://babybooktracker.montalesi.dev

iOS link here: https://apps.apple.com/app/baby-book-tracker/id6758372334

Would love feedback from other parents who read to their babies.

Snow and ice builds up on overhead powerlines. It can cause issues. States with tornados or hurricanes are more likely to build underground which avoids this. My location in SE Michigan is all overhead and, while we rarely lose power, I see tons of issues every ice storm that some unlucky few suffer through.

I live very near a hospital and suspect I branch off their higher-SLA lines so that may be a factor.

Warmer places that don't experience cold much absolutely suffer during a cold spell. Texas (with its independent grid) has been absolutely wrecked every time it gets too cold.
Ask HN: What is your AI assisted dev workflow
by lewisjoe | 2026-02-11 06:57:07+00:00
Curious on:

1. What information gets attached with pull requests / merge requests such that humans get to manage the volumes of code that AI generates?

2. What is the dev workflow in your company/personal projects?

3. What IDE+model combo is working for you?

4. What is your hack/tricks for managing large complex codebases when working with AI or are you finding utility only in small focussed repos?

> won't it make just doing a "git checkout" start to be really heavy?

not really? doesn't git checkout only retrieve the current branch? the checkpoint data is in another branch.

we can presume that the tooling for this doesn't expect you to manage the checkpoint branch directly. each checkpoint object is associated with a commit sha (in your working branch, master or whatever). the tooling presumably would just make sure you have the checkpoints for the nearby (in history) commit sha's, and system prompt for the agent will help it do its thing.

i mean all that is trivial. not worth a $60MM investment.

i suspect what is really going on is that the context makes it back to the origin server. this allows _cloud_ agents, independent of your local claude session, to pick up the context. or for developer-to-developer handoff with full context. or to pick up context from a feature branch (as you switch across branches rapidly) later, easily. yes? you'll have to excuse me, i'm not well informed on how LLM coding agents actually work in that way (where the context is kept, how easy it is to pick it back up again). this is just a bit of opining based on why this is worth 20% of $300MM.

if i look at https://chunkhound.github.io it makes me think entire is a version of that. they'll add an MCP server and you won't have to think about it.

finally, because there is a commit sha association for each checkpoint, i would be worried that history rewrites or force pushes MUST use the tooling otherwise you'd end up screwing up the historical context badly.
by gbnwl | 2026-02-11 06:57:30+00:00
You don't need to build anything. Just tell the agent to write tickets into .md files in a folder and move them to a closed foler as you go along. I've been using Claude Code with the Max plan nonstop essentially every day since last July and since then I've come to realize that the newer people are the more things they think they need to add to CC to get it work well.

Eventually you'll find a way that works for you that needs none of it, and if any piece of all the extras IS ever helpful, Anthropic adds it themselves within a month or two.
