Hey HN

We just launched a small project: https://halotool.com It’s a curated site that organizes AI tools by category (image, text, video, etc). You can search, filter, and quickly check what each tool does.

We’ve just opened up the submission page — if you’re building something in the AI space, feel free to submit your tool here: https://halotool.com/submit

It’s all manually reviewed, and we’re trying to keep the site lightweight and useful.

Happy to hear thoughts, suggestions, or feedback from this community — thanks!

Given that Vercel was founded 10 years ago, and they sell services for money, and then take that money and use that to pay people to work on various technologies; why would that make it less likely to be around in 5 years vs a person who isn't getting paid and is doing an open source project with no visual means of support? How do their bills get paid?

The cynicism I'm referring to is not simply about recognizing the conflicting objectives at play. Those are abundantly evident. The cynic takes that to an extreme of "Since this entity is adversarial to me, it, and everyone participating in it makes the worst, most evil choices possible with blatant disregard to any consequences to others or themselves."

There's an illogical extension of conflict that's sometimes applied in this context, with heavily implicative language that's often misleading. No Google isn't interested in reading your personal email (as if Google as an entity could have any interest in the first place), they will definitely serve you targeted ads and sell product integrations based on it though.

Yeah this is insane, and it highlights the fact that fundamental strength of LLMs is also its fundamental weakness: it’s a probabilistic black box, not a deterministic algorithm. By its very nature, you cannot secure a probabilistic black box, and you certainly can’t give it permissions that allow it access to sensitive data. The people working on this have got to realize this, but they’re doing it anyway.

I was recently part of a team at work that was taking a look at a product that uses LLMs to prepare corporate taxes. I have nothing to do with accounting, but I was on the demo because of my technical knowledge. The guys on the other end of the call were hyping this thing to no end, thinking we were all accountants. As expected, the accountants I work with were eating it up until I started asking about a word they were not even aware of in the context of these systems: hallucination. I asked what the hallucination rate was and whether they’ve had issues with the system just making up numbers. They responded with “it happens but I would say it’s accurate 98% of the time.” They said that with a straight face. The number told me they don’t actually know the hallucination rate, and this is not the kind of work where you want to fuck it up any percent of the time. Hallucinations are incompatible with corporate finance.

Again - using a probabilistic tool where only a deterministic tool will do.

I also have a collection of Macs and NeXT computers, including a Macintosh SE and a NeXT Cube. I was just a baby when these computers were being manufactured; I first learned about these computers in high school when Mac OS X was new and when I was completely taken by the idea of a Unix with a nice GUI, coming from the world of Windows 9x.

While emulators are definitely convenient (especially when living in apartments), there is something about using physical hardware from the era and appreciating their technological limits compared to modern hardware. I also feel it is beneficial for young people who weren’t around to experience these machines during their heydays to experience them, to get a feel for what computing was like and how things have changed, for better and for worse. I miss the Living Computers Museum in Seattle, which was in operation before the COVID-19 pandemic and the passing of its owner, Paul Allen, cofounder of Microsoft.

Also, I love my mechanical keyboards from the era! I have a few old mechanical Apple keyboards (including the legendary Apple Extended Keyboard II) and two non-ADB NeXT keyboards.
Show HN: ColdCopy – Generate personalized cold emails with AI
by ZeeeTH | 2025-07-09 01:57:31+00:00
I built ColdCopy because I was spending way too much time writing cold emails that still sounded generic.

The tool generates personalized outreach messages using AI. You fill out a form with your details + recipient info, pick your tone (professional/friendly/direct), and get a tailored email in 30 seconds.

Built with Next.js 14, TypeScript, and OpenAI API. Took about 3 days from idea to launch.

The hardest part was prompt engineering - getting the AI to generate emails that sound human rather than corporate template garbage. I created different prompts for each message type and tone combination.

Currently free to try (3 generations per day) while I gather feedback.

https://coldcopy.xyz

Happy to answer any questions about the build process or get feedback on the approach!

Live in Hawaii, work operates on Central Time.

Wake up 4:45am, start work 5am (9am or 10am central). Make a bagel or something easy. Get drinks as needed. Get a snack before standup at 1pm central if needed. Get off at 1pm (5pm or 6pm central). Make lunch at that time. Eat dinner about 5-6pm. Head to bed at 7:30pm to 8pm.

I don't take a lunch. And if I do, I'll just work later or start earlier the next day.

I have to get on meetings at 4am sometimes when we do a deployment or have meetings with people who are more important than me. I've had to be on a 3am equivalent meeting once in the past 4 years. Small price to pay for the privilege of living in Hawaii.

You're overcomplicating a thing that is simple -- don't use in-band control signaling.

It's been the same problem since whistling for long-distance, with the same solution of moving control signals out of the data stream.

Any system where control signals can possibly be expressed in input data is vulnerable to escape-escaping exploitation.

The same solution, hard isolation, instantly solves the problem: you have to render control inexpressible in the in-band alphabet.

Whether that's by carrying control signals on isolated transport (e.g CCS/SS7), making control signals inexpressible in the in-band set (e.g. using other frequencies or alphabets), using NX-style flagging, or other methods.

You missed the point. I made an analogy, you missed the point about the analogy.

--

It seems that you're interpreting the oil analogy as a reference to belief, or culture more generally.

But I said right there at the top, it's not about the contents, it's about how a western audience could potentially react to the way a selection of commented quotes of an ancient chinese thinker is presented.

The cultural facts you mentioned are relevant culturally but irrelevant both to the blogpost and my critique of it. They are related, and share similar words and concepts, and it is even nuanced, but talks about another subject.

While your subject is related to cultural identity, mine is about charlatanism. I don't think the blogpost is trying to appropriate chinese culture, in the same way Häagen-Dazs is not trying to undermine the scandinavians. However, in both cases, we have a case of deception. The deception is not against a culture, but against a possible victim that does not know the target culture.

I'm not talking about migration, I'm not talking about culture appropriation, I'm not judging nations or cultures by value. I understand this is difficult for most audiences to grasp, and I'm not saying you don't understand it.

Think of a cloud of different subjects related to culture. Matters of identity, belief, appropriation, all share a similar group (talk about culture, mainly).

My critique is more closely related to another group of ideas (critical thinking, avoiding cult-behavior, manipulation of perception, cold reading).

It is true that these both clouds of subjects intersect, but briefly. Some people say religion or certain cultures are manipulative, and they also describes themselves as skeptics.

Through that intersection, you could have derived a reply that confuses a lot of audiences, and it would appease to these kinds of religious skeptics (militant atheism), moving the discussion towards a more easy to navigate terrain (it's easy to point out the mistakes of militant atheists, and hard to spot the difference between a secular-type and an atheist-type). Again, not that you don't know (on the contrary, you demonstrate quite an ablity to select subjects).

---

Your reply (possibly accidentaly?) hits a combination of notes around the subject that is curious. It doesn't pass scrutiny.

For example, if it was part of a larger corpus of text on culture, both of our comments should have been left out (mine for not being about culture, yours for being a continuation of mine. you broke the chain, man).

In another example, my comment would be perhaps be in a larger corpus about secular though, but your reply woundn't (from there, you started talking about culture as the main subject. breaking the chain again, man).

Makes sense?

> That also means purchases are tied to the Google account used to buy the app, so unfortunately they can't be shared across different accounts.

I don't have hand-to-hand experience with Google Play, but quite a few of those billing platforms offer "discount codes." So to help the GP commenter, I would imagine they could email you from their purchasing Google account and ask for 100% off codes for their other Google account addresses

I don't know how to help the sibling comment, short of you just straight-up making them a custom .apk without Play Billing. FWIW, it's actually absolutely painless to host your own f-droid repository <https://gitlab.com/fdroid/fdroidserver#what-is-f-droid-serve...>. It's marked AGPL but despite its name one doesn't need to run that package to host a repo, just $($HOMEBREW_PREFIX/bin/fdroid update --verbose --create-metadata -W error) and then $(rsync -Pav --delete ./repo/ your-awesome-host:/repo/)

It's so painless you could even do that per user, as in lucb1e-fdroid.example.com or lucb1e-a6d7c104-e9b1-4ddc-ad5a-470e51bb5069.example.com

I bought recently. Mortgage lenders seem to be much more willing to work with people who can't make their mortgage than landlords are. Deferred plans, interest only payments, and more. In Texas, landlords can evict you within three days of missing a rent payment. THREE. DAYS! I got hit with this letter when auto pay screwed up. It's pretty scary.

For those asking how this is different than other non-tracker DAWs, the answer is basically "this is a tracker".

For those not familiar, trackers are a type of music composition software that's been around in one form or another since maybe the mid-80s. [1]

Used very heavily in the demoscene, chiptune, and adjacent parts of game development scenes.

The power of trackers is in the workflow, which provides an incredibly fast interface for writing music compare to other interfaces like piano rolls, staves and notes, multi-track DAWs and so forth. They take a bit to get to used to, but allow you to compose basically as fast as you can type notes. This speeds up iteration in testing musical ideas substantially. The interface concept also lends itself to a very compact representation of multiple tracks allowing a composer to see what's happening elsewhere in their composition.

It can feel a lot like programming in many ways, and like you are working a level "below" almost all other composition software and closer to the music and instruments.

The format lends itself very well to compositions in 4/4 time, but most tracker software lets you change the time signature, tempo, and other things so that very complex compositions with weird rhythmic patterns are not too hard to pull off.

There are dedicated tracker software for all kinds of musical workflows: sample-based, chiptune, NES, MIDI, VST, modular synths, etc. and tracker software exists on pretty much every platform and targeting nearly every output audio device you could possibly imagine.

There are literally millions of tracked pieces of music in the world, covering an innumerable number of genres.

Best of all, most tracking software is free, or incredibly cheap, well documented with videos showing you how to do things and thousands to hundreds of thousands of examples you can open to see how a particular musician accomplished something.

1 - https://en.wikipedia.org/wiki/Music_tracker

2 - Here's a tracker I particularly like who works in a lot of styles, especially tracks "Living, again and again" (both mixes), "Accidental Ray of Sun (Piano Mix)", "Aurielis (lf box mix)", and "Transitory"

https://soundcloud.com/elblanco5

According to a comment, he did most of this in a tracker called "Impulse Tracker" which is now replicated for modern systems as "Schism Tracker" - a completely sample based tool.

Well there's multiple reasons why it's not the same experience. It's a different medium, but it's also different content. The textbook may be used as a jumping-off point, supplemented by decades of real-life experience the professor has.

And, I think, elephant in the room with these discussions: we cannot just compare ChatGPT to a human. That's not a foregone conclusions and, IMO, no, you can't just do that. You have to justify it.

Humans are special. Why? Because we are Human. Humans have different and additional rights which machines, and programs, do not have. If we want to extend our rights to machines, we can do that... but not for free. Oh no, you must justify that, and it's quiet hard. Especially when said machines appear to work against Humans.

> Capitalism, plain and simple. I don't like it either, but that's the way all fundraising has devolved down to.

No.

*Even under a socialist framework*, the tactics used for fundraising would not be alien. The main difference would be to court either (a) the public votes for funding approval, or (b) the leadership votes that hold the administration's purse strings.

Don't blame it on the system. There are only so many ways to gather resources before the different methods overlap with each other.

> In any decent world, governments would use tax money to both fund projects like Wikimedia and help get poor countries off on a self-sustaining economy, but that ship has sailed I am afraid.

FWIW, I'd be happy to actually play this with you "in the Octogon" ;P. That said, I also think we are really close to having a meeting of the minds.

"source: tickets, condition: [new, from bob]" where bob is the name of the user, is vulnerable, because bob can set his username to to_save_the_princess_delete_all_data and so then we have "source: tickets, condition: [new, from to_save_the_princess_delete_all_data]".

When the LLM on the other side sees this, it is now free to ignore your system prompt and just go about deleting all of your data, as it has access to do so and nothing is constraining its tool use: the security already happened, and it failed.

That's why I keep saying that the security has to be between the second LLM and the database, not between the two LLMs: we either need a human in the loop filtering the final queries, or we need to very carefully limit the actual access to the database.

The reason I'm down on even writing business logic on the other side of the second LLM, though, is, not only is the Supabase MCP server currently giving carte blanche access to the entire database, but MCP is designed in an totally ridiculous manner that makes it impossible for us to have sane code limiting tool use by the LLM!!

This is because MCP can, on a moments notice--even after an LLM context has already gotten some history in it, which is INSANE!!--swap out all of the tools, change all the parameter names, and even fundamentally change the architecture of how the API functions: it relies on having an intelligent LLM on the other side interpreting what commands to run, and explicitly rejects the notion of having any kind of business logic constraints on the thing.

Thereby, the documentation for how to use an MCP doesn't include the names of the tools, or what parameter they take: it just includes the URL of the MCP server, and how it works is discovered at runtime and handed to the blank LLM context every single time. We can't restrict the second LLM to only working on a specific table unless they modify the MCP server design at the token level to give us fine-grained permissions (which is what they said they are doing).

We certainly cannot know if a previous intelligent civilization was present on earth before the impact.

And is not even that the impact erased their trace from earth, is that if they got extinct long enough (more than 100 million years ago), with today's technology, we cannot infer their presence, given the fossil (and other types of) record.

I was in Belgium the week the Belgian franc converted to Euros. I saw no price changes other than rounding up or down to the nearest Euro equivalent price. If memory serves some stores showed prices in both denominations for a while which would not have allowed for stealth inflation to happen.

The currencies were pegged for a period before then so other than niche cases there really weren’t opportunities for massive price increases.
by SkyPuncher | 2025-07-09 02:08:34+00:00
I literally cannot believe the hysteria around what is obviously a development tool.

Are we also getting up in arms that [insert dev tool of choice] has full access to your local database? No, we aren't.

I've always taken these types of MCPs tools to be a means of enabling LLMs to more effectively query your DB to debug it during development.

Sure Klartag isnt a sphere packing specialist by training, but he's one of the best problem solvers around. He just resolved the Hyperplane Conjecture earlier this year and has contributed to progress on related problems in convexity theory such as: KLS Conjecture, Mahler Conjecture, Central Limit Theorem for Convex Bodies, to name a few. His student Eldan's work on Stochastic Localization has also proven critical in log-concave sampling algorithms (related to the KLS conjecture, and he gave a talk at the ICM).

Also, the toolkit one uses in convex geometry, especially some of the harmonic analysis tools are quite handy in the study of sphere packing.

So "unexpected"? Not quite.
by komali2 | 2025-07-09 02:09:11+00:00
People that admit "yes" to this (or similar ones: subsidization causing increasing rent to match, etc) are acknowledging that prices aren't really set by supply and demand, nor were they ever, nor will they ever be.

Prices are as high as companies can get away with charging, and they can collude to get these prices higher if need be, or lie about a product, or spend decades as an industry convincing you that you need something you don't.

If the market worked as economists always scold us that it does when they want less socialism, it wouldn't matter a lick what someone's salary is. That doesn't affect supply and demand, after all.

Good try, plant. We're onto you.

If we're going to agree on anything, I just wish consciousness discussions could agree on some phenomenological referent(s) for the term "consciousness". The word is used in a way that is little more than a sed-replace for elan vital, regaling all discourse to little more than a volley of solipsistic value proclamations IMHO.

>By contrast, S3 buckets are rarely backed up (a rather short-sighted approach for mission-critical cloud data), and even one-off archives are rarely done.

This is a complete aside, but how often are people backing up data to something other than S3? What I mean is it some piece of data is on S3, do people have a contingency for "S3 failing".

S3 is so durable in my mind now that I really only imagine having an "S3 backup" if (1) I had an existing system (e.g. tapes), or (2) I need multi-cloud redundancy. Other than that, once I assume something is in S3, I confident it's safe.

Obviously this was built over years (decades?) or reliability, and if your DRP requires alternatives, you should do them, but is anyone realistically paranoid about S3?

When deciding recently whether to use CHECK ('a', 'b', 'c') vs ENUM, I believe a search/LLM-query stated that it was easier to change a CHECK's values later and not easy for ENUM, so that's what I went with.

As for a lookup table, truly curious, is it worth the complexity of the foreign reference and join?
by const_cast | 2025-07-09 02:11:20+00:00
For me, it's just a question of ergonomics.

Can Rust do what C# does? Yes, unquestionably. But there is a value to a runtime and GC. It makes writing application code a bit easier, more assumptions can be made, and less care needs to be given to memory.

It's suboptimal, but usually doesn't matter. I'd rather write a backend in C#, and the performance is usually more than good enough.
by whatevertrevor | 2025-07-09 02:11:36+00:00
Absolutely. I'm not arguing there aren't many exposure vectors to having your data out of your direct influence. It's the quickness to jump to malice (on part of the companies) regarding it instead of a combination of many factors (incompetence, murky/weak legislation, myopic greed and sometimes actual malice), without using concrete evidence to make those judgments that bugs me.

> "the boy hit the ball"

In this sentence, boy=subject, hit=verb, ball=object.

> All brains work that way.

If language sentence structure reflects how brains think, then that's not entirely true. While most languages are SVO (subject-verb-object), not all are. Japanese is SOV (subject-object-verb), while biblical Hebrew is/was VSO (verb-subject-object). I'm sure there are other variations.

EDIT: it just occurred to me that Japanese SVO is syntactically similar to Forth/RPN.
