Let me ask a random note-taking question.

I am a heavy user of Roam ( before that workflowy, before that org mode). I have daily checklists, but also some extensive notes on specific topics and some large projects I'm tracking.

But I'm so heavily using LLMs now to help with researching topics. And I haven't found a good way to bring my LLM usage to my note taking.

I'd love to be able to go over some things with an LLM and then tell it to add a summary of this to document X on topic Y.

Does anyone have a workflow that combines LLMs and Deep Research with a note-taking system? I'm wondering about just using Obsidian with Windsurf to make changes to it in an agent type manner.
Well, I don't have a choice anyway. I'm latino and I don't look like an approved American. It is literally dangerous for me to go.

In the early development phase, you'd compile the OS on a big non-RISCV desktop PC and target those little SBC boards, then flash it onto them and boot and test. In the prototype phase, you get the real hardware, but will probably still compile from something else. By the time the real hardware is ready to be released to the public, the OS for it will probably already be finished and ship with it.

> You do realize we all know it's impossible to have any degree of certainty in asserting the non-existence of something, right?

I love condescension that is so petty it's laughable. As the commenters said below there are very well-understood precedents/principles that allow me to conclude "no" here eg

https://en.m.wikipedia.org/wiki/Russell%27s_teapot

So no it's not "impossible to have any degree of certainty in asserting the non-existence of something", we actually have a whole branch of mathematics dedicated to exactly that (it's called probability and statistics).
This isn't quite what "bad search" means, but that search gives me a full page of ads, and I have to scroll down to even see the first actual result.
> There's a good reason for this: _it is the only way_ to run a business where the needs of customers and management changes on a constant basis.

(Emphasis mine)

And yet there are businesses which run on Haskell.
I prefer thinking from the first principles, and not according to the current computer architecture fashion.

And BTW that ID system was used in the system processing PBs of data in realtime per day back in the early 2000s, so it’s not that it was super-inefficient.
This is overly simplistic. I don’t fault you for it, but it shows a lack of understanding how a business functions.

There is a lot of overhead that goes into running a business, as others have mentioned. Taxes. Rent. Utilities. Licenses. Certifications. HR, testers, project managers, product managers, people managers, directors, marketing, customer service, sales, C suite, and on and on.

I know right now you might be saying “those people don’t even do anything! Developers are the only people making the damn product!”. Again, a business is kind of like a product of its own. It takes many moving parts to take a usable product and get it to market, fight off competition, work with government for regulations (or keep from getting regulated), find and get customers, etc.

Once you try and “go it alone” you will realize that creating the product is only one small part of making a functional and profitable business.

I run a small business. I don’t use half of those roles I mentioned and there is still a lot of overhead. It is very easy to underestimate the amount of extra work involved.
I am not affiliated with the strikers, but I think the idea is that, for now, the companies still want to use at least some human voice acting. So if they want to hire them, they either have to negotiate with the guild or try to find an individual scab willing to cross the picket line and get hired despite the strike. In some industries, there's enough non-union workers that finding replacement workers is easy enough. I guess the voice actors are sufficiently unionized that it's not so easy there, and it seems to have caused some delays in production and also some games being shipped without all their voice lines.

But as you surmise, this is at best a stalling tactic. Once the tech gets good enough, fewer companies will want to pay for human voice acting labor. Unions can help powerless individuals negotiate better through collective bargaining, but they can't altogether stop technological change. Jobs, theirs and ours, eventually become obsolete...

I don't necessarily think we should artificially protect jobs against technology, but I sure wish we had a better social safety net and retraining and placement programs for people needing to change careers due to factors outside their control.
Eddy Cue did an amazing job with the original Apple.com online store in the late 90s, the first version of the iTunes Music Store, and the early App Store. Interestingly these were all big WebObjects apps.

I wonder if there’s some interesting server-side technology culture story here and how it trickles down to the way services operate for consumers on the client side. Just pure speculation.
While I agree with you, this is a huge issue with the term "security" and what it means to "provide security" as a government, because at some point almost everything can be labeled as a "national security threat" if it happens to be against the political desiderata of any one controlling said governments at a certain moment in time.

I feel like this sort of "security reflex" only got worst after 9/11, it was already there before even before that point but starting with Bush jr. it cascading into lots and lots of non-military related areas.
> If you are not already deeply familiar with the subject matter, it is going to be hard to appreciate why particular names have caught on

and if you're introducing a niche term to a broader audience who might lack that context, in an asynchronous or static medium like an HN post or repo README, providing a definition that describes it in more widely used terms is a low-effort way to help unfamiliar people learn about it without forcing them to ask

Market prices are based on whatever number the investor decides to make up.

Whether it be another investor or a website telling them to do so. There is no basis in reality.

The "housing shortage" is really an "affordable housing shortage". Don't get the 2 confused. One is based on reality...one is based on speculation.
Sure it is.

This discrepancy appears in physics too. It's common to use 1,2,3 for spatial indices, but when you reach enlightenment and think in terms of spacetime you add a zero index and not a four.

Funny, how we're all suddenly privy to highly classified information.

Yesterday, if you'd have publicly shared this one substation is enough to take down Heathrow for an entire day, you'd have been disappeared by the British spooks for sharing extremely sensitive information threatening national security and you'd probably end up behind bars for over a decade.

I'm surprised how often Freudian ideas like projection are accepted uncritically despite what seems to be weak evidence for them.

Does that count only the actual airport? It doesn't count the potential business travellers contributing to the economy in different ways. Like if half of the financial sector were due to arrive at Heathrow, where would that be in the analysis?

Just to downplay the importance of Heathrow through numbers is a bit absurd.

Hey Hacker News,
I’m excited to share LangManus, an open-source project that’s all about community-driven AI automation. Built on the shoulders of amazing open-source work, LangManus combines language models with specialized tools to tackle tasks like web search, crawling, and Python code execution—while giving back to the community that inspires it.
At its core, LangManus uses a hierarchical multi-agent system, where a supervisor coordinates a team of specialized agents to handle complex workflows. It integrates with LLMs like Qwen and powers up with tools like Tavily for search and Jina for crawling. Plus, it comes with Docker support and a web UI to make interaction a breeze.
Want to see it in action? Check out the demo video: https://youtu.be/sZCHqrQBUGk. In it, LangManus calculates the influence index of DeepSeek R1 on HuggingFace using a fully automated plan—think web searches, data retrieval, and Python code crunching, all seamlessly tied together.
Here’s what makes LangManus stand out:
Multi-Agent Magic: A supervisor delegates tasks to agents like Researcher, Coder, and Browser for efficient execution.

Tool Integration: Web search with Tavily, neural search with Jina, and Python REPL for coding on the fly.

Ease of Use: Docker-ready and a web UI for quick setup and control.

If you’re into AI automation, multi-agent systems, or just love contributing to open-source projects, swing by the GitHub repo: https://github.com/langmanus/langmanus. Dive into the code, play with the demo, or drop some feedback—we’d love to hear from you.
Join the community and let’s build something awesome together!
The patent for the PET soda bottle was granted to one of the Wyeth brothers!

https://patents.google.com/patent/US3733309A/en

The patent says they are good to 100 psi for regular operation and people pump them up to 2x that when they shoot them up as rockets.

It's fun to make a "chemical pressure bomb" out of that kind of bottle, the classiest way to do that is to use liquid nitrogen, the second classiest way is to put in a pellet of dry ice, if you have no class at all you put in some aluminum foil and either a strong acid ("The Works" drain cleaner) or a strong base (Lye/Sodium Hydroxide) which in either case will evolve hydrogen. [1]

The dry ice version goes off in 30-45 minutes if you put in just the pellet, if you add some hot water it works like a hand grenade and will explode less than a minute, cold water is intermediate. These are dangerous at point blank range

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

but in my experience harmless 10 feet away. [2] [3] When I was in college my friends and I made a bunch of them and threw them into a vacant lot at night and thought 30 minutes later that we'd failed, but soon we heard a series of loud explosions which caused the neighbors to call the police. The cops drove by and shined a spotlight into the area and we were worried that the last one would go off when he was there but it exploded just after he drove off.

[1] ... and spray dangerous chemicals. Don't do it.

[2] had one blow the bottom out of a small plastic waste basket though and read a report which I couldn't find this time about a high school chemistry teacher who tried this in class and it blew up in a student's hand, blinding him

[3] usually the bottle is torn up such that most of the plastic is in one big piece with jagged edges, today people would worry about microplastic generation

No, those policies only matter, definitionally, in so far as they actually affect the elasticity of supply. The elasticity of supply is what they measured and found it does not matter, ergo those policies (and all related hypothetical supply-elasticity-affecting forces) effectively do not matter relative to other factors (well, one factor in particular: income).
Punishment's main goal is to discourage the behavior. If old one doesn't cut it anymore they usually make it worse, no matter the times we live in, or subject. That's how it goes, anything to stop bad behavior.

> The smart thing would have been just saying he wanted the iPhone to be smaller, money and resources is no object and we're willing to dedicate time/people to this project to get proposals put together.

That's just bland business-speak. Jobs had a knack for illustrating things in unexpected ways and this was it. I have no doubt that whoever saw the fish tank thing had the same takeaway as if Jobs simply said he wanted the iPhone to be smaller and there would be resources dedicated to it.

That's very strange to me that they do it everyday. I thought training runs took months. Do they throw away the vast majority of their training attempts (e.g. one had suboptimal hyperparameters, etc)?
> You say you learn of them through your friends. How do they learn of the products?

I don't know, but it's possible that they could do it the same way I do: as a result of actively researching solutions to a problem I'm facing. Or maybe they see ads. However it enters their awareness isn't important to me.

Ads aren't important to me for product discovery. When I need a product, I go looking for it. I don't need them to come looking for me.

> How do you feel about that as a middle ground?

In order to target ads to me, someone needs to be tracking me. Whether it's the advertisers directly or a middleman is not an important distinction for me. In order for me to get paid, someone will have to know my identity and how to pay me, and records will be kept about what ads I've paid attention to and what ads I haven't. I personally find that unacceptable. Is your system able to avoid that?

See https://waterockets.com/ for commercial kits for making really fancy pressurized water rockets, even 3-stage rockets! You can get many many uses out of a bottle.

In Larry Niven's Known Space books, rockets are launched from earth using some kind of super-compressed material encased in tanks made of some unobtanium, a vastly improved version of those water rockets.

I can't wait to read that blog post. I know you're an expert in this and respect your views.

One thing I think that is missing in the discussion about shared data (and maybe you can correct me) is that there are two ways of looking at the problem:
* The "math/engineering" way, where once state is identical you are done!
* The "product manager" way where you have reasonable-sounding requests like "I was typing in the middle of a paragraph, then someone deleted that paragraph, and my text was gone! It should be its own new paragraph in the same place."

Literally having identical state (or even identical state that adheres to a schema) is hard enough, but I'm not aware of techniques to ensure 1) identical state 2) adhering to a schema 3) that anyone on the team can easily modify in response to "PM-like" demands without being a sync expert.
I worked at IBM for 7 years and I worked with mainframe and AS/400 systems while I was there.

If you want to learn Mainframe and COBOL for fun I say do it. I did enjoy working with those technologies and you probably will too.

However if you want to do it because you think you'll make lots of money, unfortunately that is not the case. Yes I know you hear all the time about how COBOL programmers make bank. That is not quite true. They are not looking for people that know COBOL or Mainframe. They are looking for people that know their big ball of mud. If you know their big ball of mud they'll pay you a lot. However if you just know COBOL and they have to train you on their big ball of mud. Well they would rather send that work offshore to pay the lower wages. Any work done onshore is paid at low rates.

I haven't touched those systems since I left IBM 15 years ago. In fact I don't even have it on my resume anymore. Cloud technologies pay so much more and the jobs are easier to get.
Probably because of easier access to qualified workforce.
Show HN: I made "specloop" – O1 prompts to codegen
Hello HN,

I made a local nextjs app that walks you step by step through ideation, specification, and implementation planning for a fresh dev project. It's a utility that pieces together prompts so that o1 can do the heavy lifting.

Ideally you would use the prompts from https://www.jointakeoff.com/prompts ( no affiliation ) or craft your own if you have inclination. You the put the prompts into the app and run through the steps.

Warning! It works really well if you have a good project scaffold already to feed into it. I'd be great to collect a bunch of excellent starter templates for this purpose.

Dispatch could correlate it with the jet stream to see if they are getting good fuel consumption. If it's inefficient, subsequent aircraft might plan a different route.

Several years ago I saw a story about the a new record set for fastest Atlantic crossing by a subsonic civilian flight. And due to wind conditions it flew across the US instead of the polar route (it was like LAX to LHW). Basically they just flew with the jet stream and had such a good tailwind they had a supersonic ground speed. 6 or maybe even 700 mph. Their route was much longer than polar but was more efficient because they had a 150 mph tailwind.
The specificity reason is interesting as it relates to what feels like an assumption in software that all software components are neatly shaped boxes that a) perfectly encapsulate an area of functionality and b) can be placed into neatly shaped holes of 'required functionality', neither of which ever seem to be true.

The boxes are always weirdly shaped with odd edges, and the holes they have to fill are always oddly shaped. The code written to join the two is at minimum glue that seals the two edges, but also usually involves converting one shape to another.

I will ask a dumb question as someone who knows nothing about this stuff (since you already have good questions by smart people):

How close is something like this to being competitive with ray-tracing (as featured in video game engines, or as featured in something like Blender)? I guess, since it is using Torch it should be… surprisingly performant, right? You get some hardware acceleration at least.
