At the moment the measures taken are:

- Full content analysis by Primary LLM (Default is Gemini 2.5 Pro) with link hard-coded alongside each piece of content with structured output for better parsing. - Temperature right down (0.2), strict instructions to synthesize, precise prompts to attribute links exactly and without modification.

What I hope to introduce:

- Hard-coded parsing of links mentioned in final report to verify with the link map created throughout the research journey - Optional, "double-checking" LLM review of synthesized content to ensure no drift. - RAG enhancements for token-efficient verification and subsequent user questions (post-research)

Do you have any further suggestions?

Right now I hope to strike the delicate balance between token efficiency, with enhanced grounding as optional settings in the future. I have a big task list of things, and this is one of them. I will ensure to re-prioritize alongside user requests for the different features.

Of course, being open source, contributions are highly welcome. I would love to see large community involvement. Collaboration benefits everyone.

P.s. I have spent hundreds of dollars in tests. I'd say for every 1 hour of building, about 3 hours of testing have gone into this, debugging, optimizing quality, ensuring guard-rails are in place.

If you go to the repo, also check out the config/prompts.py file - it will give you a little more insight into what is going on (there are code checks as well, but generally it gives you an idea).

I've spent the last three years building a game engine specifically to do this, and currently finishing the final draft for the game story I've created to go alongside it.

Happy to share anything you'd find helpful. The big takeaway for me has been, you're going to want to graph out the impact of choices before you write the story. If you know the flow of decisions, then that gives a much clearer structure than trying to write the story first and then create branches off it. I think the reason is that it sets a much tighter scope for the writing doing it that way, whereas if you write the story and then find ways to branch it, the scope for that is functionally infinite.

Got any specific questions?

I've thought that recently there are things I'm willing to build, things I'm willing to sell, and things I'm willing to support. My desire for each is not in equal measure. There are vastly more things I will build for myself then I can sell, and there are a lot of things I like selling but I hate supporting. Only when I feel the trifecta do I release it to the public. The rest I tell myself I can just enjoy the process of building and throwing it away if I want, it doesn't matter.

Socialism is defined by social ownership of the means of production. But in those countries, the society did not really have a say in managing the means of production, everything was in the hands of the 'avantgarde party' which inevitably led to centralization of power in the hands of a small clique.

Total socialism is of course unworkable anyway, but this was no socialism.
Why are there many startups founded by ex 8200 units (Israel)?

I'm genuinely curious why

Port.io founders are ex-8200 unit.

The co-founders of Wiz—Yinon Costica, Assaf Rappaport, Ami Luttwak, and Roy Reznik—are all veterans of Unit 8200

I agree, LLMs have biases. It was my primary desire to build this tool and put the weight on the LLMs to synthesize rather than think about and interpret the subjects. It's actually the main goal of this tool - maybe I don't articulate that as well as I could be - I'm open to suggestions here!

I agree to first figuring out which research is most important and reliable. There is a planning stage, to consider the sources and which ones hold credibility.

In addition, the user has full control over the sources the tool uses, and even add their own (MCP tools).

In addition, being open source, you have full control over the flow/prompts/source methods/etc and as a result can optimize this yourself and even contribute improvements to ensure this benefits research as a whole.

I welcome your feedback, and any code amendments you propose to improve the tool. You clearly understand what makes good research and your contributions will be highly valued by all of us.

If you force every SWE to go to legal for every technical decision, or ask for permission, it's not scalable, yes. On the other hand, if the team is in the long haul of developing this kind of regulated applications, the knowledge will get accumulated over time, and it'll trickle down from product managers to seniors to juniors.

This is the kind of tribal knowledge you want to spread among a development team, and if a collaborative document of "Why it's done this way" can be propped up with pointers to relevant sections of the regulation, it'd be a very good thing.

Not unlike NASA's global Lessons Learnt document.

Just as mutually assured destruction brought lasting peace on the international scale, widespread civilian ownership of military weapons has also been a remarkably effective deterrent and safeguard against would-be tyrants across history. If both Karl Marx and the US founding fathers agreed that a well-armed public is important for a lasting civil peace, it's probably a good idea to listen.

I started experimenting and I think this builds out pretty neat estimations from jira tickets/other descriptions. When I was sitting in the CTO role, I spent a ton of time talking with people about how long/short various projects would be. When I was a developer, I hated the estimation piece because it felt like it was both keeping me from building and was almost never done with enough context to get really accurate results.

I was playing with the OpenAI API and I noticed that they can actually return a set of probability x next tokens and I thought that it might actually give you kind of cool ways to see the distribution of potential outcomes. (You can see an example here: https://universalestimator.com/estimates/c68db45b-7622-4bab-... that looks at a detailed ticket for implementing filtering on a dashboard.)

At 20mph in a well-designed street, there’s still a lot of opportunity for people to keep themselves safe. Not so much with guns.

On badly designed streets and with bad and/or speeding drivers, on the other hand.

And don’t get me started on the dangers of cars with high hoods. We’ve known for years that to keep pedestrians and cyclists safe, they need to go on top of the car, instead of under it.

> 2. Work visa conditions if harsh enough are akin to slavery. You have Indians on H1B visas for over a decade with no chance of getting a green card. They have bought houses and raised families here. And can be kicked out in 3 months if they are out of a job. They are stuck.

Sounds very stressful. Is there no way for them to replace the H1B visa with something more permanent? Kinda like a middle step to green card?

Indeed.

Which is why these coupons and deals aren't "McDonalds is actually still cheap!". Their non-coupon pricing has risen to absurd levels, and part of what made them tenable was their speed. They used to be basically instant, I'd drive through, or go in and have food in 2 minutes. (20 years ago)

And thus their coupon pricing is just as high, comparatively.

One should also bear in mind that a soda costs them under a penny, the straw costs more. And a bunch of cut up potatoes are barely pennies.

And now it can take 15 minutes to get food at some McDonalds, which is pure dumb. For their prices, I can get food in a real restaurant, and with their speed, a real burger just as fast now.

They are literally insanely expensive compared to 10/20 years ago, with much slower service, and less customer service.

Have you ever lived with or helped a person with AD? It's not cellular senescence. What you're talking about is fine and well, but AD is a devastating disease that has very particular symptoms. We may not know all of the causes, but reversing cellular senescence isn't going to solve this.

Researching and curing AD is not barking up the wrong tree. There is a horrible deadly monster in that tree that needs defeating. I hope people also get scientific funding for other age-related issues.

Well I ran a bunch of tests and it turns out that the performance wasn't actually impacted very much after all. So the changes are official. I also made some other adjustments to the default behaviour; if no pattern is specified then it just matches everything. In other words, "path -f" prints every regular file in the filesystem (starting in the current one). Anyway, thanks for the suggestion, otherwise I may not gone down that (decidedly satisfying) rabbit-hole!

I have come across the same 'explanation' multiple times but do not find it satisfactory.

>> This "battle of the infinities" cannot be won by either side, so a compromise is reached in which theory tells us that the fall in potential energy is just twice the kinetic energy, and the electron dances at an average distance that corresponds to the Bohr radius.

This "cannot be won by either side" isn't a good explanation of the problem. By saying "a compromise is reached in which theory tells us ...", the article seems going around the answer instead of actually telling the answer to the question.

Assuming relativity is not invoked and given a finite size of the nucleus, what is actually bringing this situation of compromise? What is pushing the electron (or its probability cloud) outwards to counter-balance?

Agreed. I’m getting close to a video to put on the landing page, probably some time next week.

The first time user experience is really bad, but the app itself makes a lot of sense once you see it in action. Feel free to get in touch with me (there are several methods listed when you log in) and I can give you a personal introduction!

If not then check back in a few weeks for a cool video :)

Non-violent communication (NVC). The name is a bit wonky, but the principles are sound. I'd personally rather call it empathic communication. Especially using NVC towards myself was an eye opener, to the point where I do see some intersection with personal philosophy/spirituality there. But I mostly use it to tease out what needs I and my conversation partner have. I normally get trapped into focusing on the content of a discussion, NVC helps me to stay out of that trap and allow me to shift focus on feelings, needs and solutions to meeting them when it is appropriate.

Ah so nobody called for the death of JK Rowling, but terfs in general, which she happens to be? A death threat by nonintrinsic affiliation if you will? Seems pretty stupid if you ask me.

Perhaps she could not make it her whole identity so that when people say "death to this specific type of bigotry", random people on the internet don't immediately make the logical leap to think people wish for her death specifically?

In all seriousness, being able to pinpoint what is causing the possible stress / load and making choices to get rid of that is pretty amazing, props!

Though as for the job market, I’m sure the AI hype will blow over but I don’t think it’ll remain silent for long, there’ll be another nonsensical trend within reach.

Tech needs to keep innovating to keep investors happy and keep investing. That’s why it’s going this AI bubble route. Cause they don’t have any groundbreaking innovations at the moment but want to keep the investors they got when the web was newer and was worthy of the real hype.

A pentagonal geospatial indexing system: https://a5geo.org/

If you’ve used H3 or S2 it should be familiar, the major difference (apart from the fact it uses pentagons) is that the cell areas are practically uniform, whereas alternative systems have a variance of around 2 between the largest and smallest cells, making them less useful for aggregation. The site has many visual demos, e.g. https://a5geo.org/examples/area

The code is open source: https://github.com/felixpalmer/a5
by throwaway13337 | 2025-04-28 09:06:44+00:00
Agreed!

When I was learning to drive, I was afraid of hitting the curb. It made me a bad driver. My driver's ed guy told me the common sense advice of 'don't pay attention to the curb - watch the road'. When I internalized that, I drove much better.

It was so simple.

We cannot even conceive of a good future today. We have no vision of what the better future looks like. We need positive fiction to help paint the picture.

Paying attention to the negative just gives you more negative.

The hard question is why it is so hard to imagine a good future. Maybe because we no longer understand our own core problems deeply.

The world waits for the new story.

This is my perspective as a U.S. citizen. I think several things are happening:

* Border news and ICE detentions are a hot topic right now, so some of the stories you see were (unfortunately) business as usual. Border agents can be assholes.

* The number of people in ICE detention hasn't actually increased under Trump from the data I have. It was increased substantially under Biden.

* I would love data on the rate of detentions at the border, but I suspect it is in the upper hundreds per day. I heard that we turn away about 800 people per day at the border. It's a risk, but not a very big one unless there is some factor that makes you high risk.

* I suspect that Trump is either pressuring ICE to increase border apprehensions or at least allowing dubious ones to go forward, unfortunately. That said, an airport only has so many cells. They still need a reason, even if it is quite flimsy.

* If I were a green card or visa holder and had no criminal past, no controversial social media presence, I'd still take the risk of traveling, but I'd be very cautious about following the rules on imports (no food, no cash, strictly in financial limits). Consider having the number of an immigration attorney.

* If I had even a minor criminal past, have travelled to countries considered problematic, are a journalist/activist, plan to stay out of the country for many months, or anything else that might make me high risk, I'd just cancel any optional travel.

If you are a small to mid-sized team, moving to Bazel is massively painful and basically requires up to one full-time position to provide your team with a good experience.

Grog on the other hand let's you keep your existing build setup while just parallelizing and caching it. It's not a full replacement, but it's more than enough for most mid-sized teams that want to have fast mono-repo builds.

At least for me, I enjoy trying to solve problems using code. Kind of like how some people enjoy solving cross-words, math problems, and what have you.

As for the larger things that could potentially lead to a business, those types of problems usually come from something I encounter at work. If I'm stuck using software that sucks, identify some obvious demand, etc.
by raverbashing | 2025-04-28 09:10:39+00:00
Yeah

For the specific purpose of what the article presents, I feel something simpler like 10%/50%/90% times can be better (two systems that have times as 0.1/1/10 or 0.9/1/1.1 will have "the same average" but where one might be adequate the other one might not)

This could be helpful even for people who already have internet access. The internet is full of distractions, and we often end up seeing ads instead of actually learning something. It would be great to create personal collections of useful websites and have a powerful search tool to explore them—without relying on Google and getting sidetracked.

Right now, Kiwix’s search function is quite basic and doesn’t work well with large amounts of content. It might be worth exploring the use of a generative language model or embedding model to improve its accuracy and usefulness.

[EDIT: people downvoting this, how about you explain what you object to in it]

> It's really a bummer to see this marketed as 'AI Discovers Something New'.

The headline doesn't suggest that. It's "AI Helps Unravel", and that seems a fair and accurate claim.

And that's true for the body of the article, too.
Show HN: I just launched Frames, a note app for Analog Photographers
by ydstmw | 2025-04-28 09:11:56+00:00
Frames is a simple app for analog film photographers to log shot details like camera, lens, film stock, exposure settings, and notes while shooting. Later, it can embed this metadata into scanned JPEGs to keep the technical and creative context of each frame.

The iPhone app lets you record notes in the field, and the companion Mac app helps attach metadata to your digital scans. There's no cloud storage — everything stays local. The iPhone app is free, and the Mac app has a 7-day trial.

I built Frames because I wanted a lightweight, privacy-first tool to bridge the gap between analog shooting and digital archiving. It's designed for anyone shooting 35mm, medium format, or large format film who wants to organize and preserve their work better.

More info: https://withframes.com

Happy to hear feedback!

Because you framed it as a Technical Partner needing a 'Business Guy' and approached someone from the post-2000 Cohort who uses the Wozniak/Gates power-dynamic as a best-practice case study (or RIM's example of Mike Lazaridis/Jim Balsillie).

The fact that you spent months refining the idea and building out prototypes is irrelevant or even detrimental to your position. In fact it may have represented a delivery anti-pattern depending on how far along you were to realising your value proposition as a product. Engineers to build MVPs are a dime a dozen. Why were you wasting time as an individual contributor when positioning yourself as a (co)-founder? Why would a prospective C-Level Business Strategy Leader see you as anything other than an Engineer with a MVP and no GTM, previous exits aside?

This is a common scenario for those who frame themselves as 'Technical Founders' - they end up being perceived as a cost-centre incapable of realising any sort of a GTM strategy, and as such are equity-weighted accordingly.

I am working on an app for rhythm training for dancing. The first step is beat detection in music - here is my code for generating videos with beat counting: https://github.com/zby/beat_counter (vibe coding warning). Beat detection seems to work OK, downbeats are a bit more tricky and I have found not good solutions for further structuring of music (for dancing they usually count to 8 - that is two 4 beat measures - or 6 - two 3 beat measures for Waltz for example, I am not sure about 2/2 measures and other). Seeing all the LLMs generating music I thought there should also be LLMs interpreting music - but so far I have found no such model the available algos seem to be from a previous decade.

My current plan is to test the counting with people with good rhythm sense and once I find a good algo for beat detection I'll proceed with writing the app.

Ok, so lots of sources that don’t show what was originally claimed (i.e. someone holding a placard at a recent protest in London calling for the death of JK Rowling).

I don’t know why it irks you so much that people would fact check this particular claim. I agree that it’s not central to the original poster’s overall point, but it’s not ok to invent facts just because your argument could probably get by without them.

An uneducated populace is generally easier to control - the easier it is to threaten their livelihood, the harder it is for them to rise up. Further, there's a clear correlation with education and what political ideologies you're likely to vote for. And, of course, if you long for the "good old days" when society was run by white christian men, then why would you want to help anyone else?

I was wrong about absolute numbers, still if you subtract suicides and gang infightings reckless driving kills and hurts way more people.

>>Gun utility: small Car utility: large

It's not about cars but speeding in cars. You can eliminate one without the other. This is not the case with guns. Utility of speeding is negative even if you never kill anyone.
