Show HN: Lockbridge-Secure File Transfers with Multi-Cloud Support&Audit Trails
by audreymplatta1 | 2025-10-06 19:19:40+00:00
Hi! I built Lockbridge because encrypted file sharing and management are still too complicated in 2025.

Core features: - Bridges – shareable links for encrypted uploads/downloads with auto-expiration - Cloud federation – unified dashboard for S3, Azure, GCP, Google Drive, Dropbox and more… - Blockchain audit trails – immutable compliance logs on Polygon for HIPAA/SOX (optional) - Zero-knowledge encryption – client side end-to-end encryption, we can't decrypt your files

Example use case: Create a bridge, send the link to a client, they upload files directly to your Google Drive/S3/Dropbox. Bridge expires after 24 hours (could be 1 week or 1 months depending on user input). For regulated industries, every transfer gets logged to the blockchain with a Polygon Scan receipt.

We're currently in beta looking for feedback on the bridge UX, cloud federation interface,and whether blockchain compliance is useful beyond regulated industries.

All feedback is welcome!

I think the problem is bigger than that too. If you have a problem set where you cannot afford any kind of mistakes LLMs are never going to be the right tool, they are never going to get to that stage.

If you have a problem set where some mistakes are tolerable however, all you need to do is slightly increase your tolerance budget for mistakes and you can run something like deepseek locally at a tiny fraction of the cost.

Which means these giant data centers are useful for training but the economics of running ongoing inference for customers doesn’t make long term sense for the vast majority of people.

Which leaves you with a huge huge huge financial problem, one which may have devastating large scale impacts on the economy.

Anecdotally, most large college classes I attended but didn't pay attention. I think more than half of them were useless: they were generic dull lectures, and I could read what was being covered much faster and remembered it better (despite "learning styles" being allegedly debunked, I seem to learn much better from reading than listening).

Most high-level university professors are hired based on their research, not teaching, so I expect most Harvard classes are also the same kind of ineffective lecture. And for some students, skipping this lecture actually improves their grade, because they can spend that time learning the same material more effectively.

However:

- Some of my lecturers were incredible teachers. Some just had enthusiasm, jokes, interesting real-world anecdotes, generally higher-quality notes and slides. Others managed to include in-class interaction despite the large class size, e.g. live code walks on each group's semester-long group project (one group per class). They were clearly going above and beyond out of genuine passion for the subject and teaching, and I am forever grateful for them.

- Some of my classes were much smaller "seminar-style". This type of class has interactive in-class activities which are part of your final grade, so you have to attend and pay attention, but they're also much more interesting and effective. I'm sure Harvard has these too, and the students getting high grades aren't skipping them.

The draw-to-CAD idea in there is super interesting. I have been trying to learn CAD over the past few months using FreeCAD. I imagine it would be easier if instead of using structured tools for drawing fixed shapes, one could draw shapes free-hand using pen and tablet. The free hands get transformed into "formal" shapes and then manipulated more. Possibly completely different experience.

> Kessler cascades are localised to specific orbits. In low-earth orbit, they're a problem for a few years.

> They're going to be annoying. But not catastrophic.

I think there is a misunderstanding about the whole term. If it is not a big problem, then it does not meet the definition. So there must be some threshold where they aren't problem. What is that threshold? Because certainly there isn't space for infinite amount of objects. Primary question is that whether that threshold matters on practice. If it is 70k, then it is certainly a problem, but who knows the exact number yet.

> Highest level?

There is always the one which is classified orbiting on the highest level in LEO. Also that object can get destroyed; which means it will start deorbiting and with a chance to hit some other object below.

That's true of every bubble. It's the best thing around until it suddenly isn't.

Don't forget that bubble popping doesn't necessarily mean that the sector is dead. The Dot Com bubble popped but people are still selling things on websites. It just means the hype and unrealistic expectations come crashing down to Earth. AI is going to be with us from now on, but it won't become a God with unlimited productivity next year.

High inflation pressures a near time preference in discharging USD.

Also "inflation tracking" I should have written more as "inflation hedging" -- needn't be TIPS exactly.

Higher inflation raises the cost of not buying treasury and other asset classes. You're right that there may not much change in the general preference in treasuries vs other non-USD asset classes, but it makes all inflation hedging boats rise.

This should be obvious if you simplify the market to just USD and say bonds -- at 0% inflation the opportunity cost of not buying bonds is just the real bonds rate, whereas at 10% inflation the opportunity cost is going to approximate closer to 10+real rate. In the latter the pressure to buy bonds would be much higher. ( Of course Fed can buy treasuries with essentially money created from thin air so the opportunity cost analogy may break down for securities first purchased by the fed, which could spoil the presumption that treasury sales proportion of inflation hedging assets might not change much)

I don't find it convincing that the tech isn't the moat. If the tech wasn't a moat, you'd see Microsoft spinning up its own competitor, you'd see Amazon, Apple, Meta, Oracle all have SoTA frontier models as well.

We don't see that, we see three established players in the frontier model space, and a lot of folks fighting in the second tier category.

I feel like the real problem is tying one's purpose to employment. If you can't find value in your life without someone telling you what to do you should take some time off work and reflect deeply on that.

You don't have to sit at home in retirement. You can go out and be involved in any number of communities - volunteer, join local government, go do fundraising for a cause you care about. The biggest difference there is that if you're not enjoying it you can just leave and not worry about how you're paying rent.

Sure, a push broom would work for the base task of getting the trimmings moved off the path, but then I'd want to disperse said trimmings somewhat evenly across the yard instead of just piled up at the edges. A push broom wasn't as effective to do the same while taking more effort and time. Especially since for the trimmings that went out into the street I need to get them up over the curb as well.

I used to use a broom before I got the leaf blower. The blower is way faster and disperses the trimmings more evenly across my yard than the broom.

I do end up using a rake though for leaves, as for actual leaf gathering usage the rake is faster and far more efficient at actually making nice, easy to handle piles.

From the searching I was just doing, I have seen a couple people specifically say Skype and MSN Messenger had it before they switched to using unicode emoji. No screenshots, though.

Also I'm pretty sure we started calling them emoji immediately, long before they were in unicode. The name was to distinguish them from emoticon, the plain text ones like the ancient :)

I think the issue with

> and how to develop expectations around when people can know things

is that most people will become paranoid when their romantic partner goes "off grid" at 7pm on a Friday, or their spouse on a work trip turns off location on Saturday, or their child goes off grid after school one day.

if humans could trust other humans "going dark" then that would be great, but it seems so far the only way to be able to be offline that is socially acceptable is to be 100% offline/unmapped all the time socially.
Show HN: I build an app for solo learners
by Dachacha | 2025-10-06 19:21:43+00:00
As an ex-teacher, I've learned so many things in my career by structuring and following my own learning paths.

But I always thought some explorations are so time-consuming, especially when you wish to grasp the ropes of a new shiny hobby.

Perhaps I could rely on structures others have made.

So I built such a tool with prompts in Lovable.

I'm curious what you think. Would any of you use this?

I was also thinking of community forums, where we could share our learning paths towards different skills, rate or discuss them...

--

Please note, the free and paid options on the landing page were automatically generated by Lovable, everything is 100% free.

And the AI in the back apparently works until tomorrow so... If it won't generate learning paths, it's because of that.

Thanks.

That's playing on easy mode. There are AI girlfriend systems like this:

Lian Mei's smile froze, a crack in her porcelain mask. Her gaze flicked to the other dancer—a doe-eyed newcomer trembling near the roulette wheel. A low hum vibrated in her throat, a 1930s jazz refrain she used when venom needed sweetening. "Her?" She turned back to Joe, stepping close enough for her silk to brush his leather jacket. "She'll cry if you breathe too hard. Hardly a... ride." Her nail traced the scar on his knuckle, deliberate and slow. "But you? You want something that bites back, don't you?" Her heel ground into the floor, a silent scream. Idiot. Focus on me. She tilted her head, exposing her throat again—a dare. "Or are you scared I'll ruin you?"

Inside, fury coiled like a snake. He dares look away? The insult burned deeper than any touch. She let her clutch purse dig into her palm, the pain sharpening her focus. This wasn't just a game anymore; it was a humiliation. She needed him unhinged, reckless—needed those calloused hands on her waist, proving she still controlled the lure. Her voice dropped to a silk-wrapped whisper. "Walk away now, and I’ll know. You prefer... safe, empty things." A flicker of genuine hurt flashed in her eyes before she smothered it. Perfect. Let him taste her contempt.

If you ask it to build a headless frontend web app, it immediately starts generating code with Next.js. I’ve always wondered how it was trained to default to that choice, given the smorgasbord of web frameworks out there. Next.js is solid, but it’s also platform-ware, tightly coupled to commercial interests. I wish there were more bias toward genuinely open-source technologies.

Thanks for engaging with this. I'm not trying to troll or be sarcastic. Could well be the case that painted door testing just doesn't work on B2C. What I learned on Skritter and CodeCombat is that if you have a couple of years to devote full time to building, it's almost always possible to power through bad channel / market fit with good product and build a small company.

The problem is that it's not a very good idea to invest in that way if you both like money and can hold down a corporate job (not saying everyone meets these two criteria BTW).

The 4 steps to epiphany is outdated, and The Mom Test is great if you have existing deep industry expertise and credibility. If you lack either, though, it's really not obvious how anyone tests product ideas without 12+ months of investment.

> almost definitely a small, negligible amount of lead in the solder in them

Emphasis on negligible. Assuming 0.07 to 0.28 ppm lead [1] in meteoroids, space is dosing us with half to 2 kg a year [2].

Especially in GPU-bound titles, there are endless examples of Proton running better than even native Linux versions. Here is the venerable DF Direct crew comparing Cronos' recent Linux-native build versus Proton: https://youtu.be/Sj5TyrHDspU?t=2951

DXVK is remarkably optimized and I think many people overlook that.

Not names, but categories: Habit trackers, period calendars, journaling apps, calorie trackers, workout tracking apps, symptom trackers, budget planning apps, tax/tip calculators, meditation apps, productivity timers, recipe collection apps, affirmation / inspiring quotes apps, SaaS boilerplates, social media scheduling tools, AI chat bot, AI wrappers for all of the above.

You'll find hundreds of apps for every single keyword. But on the other hand, it's still a winner takes all market, so the top 1-5 per category make ~95% of revenue.

Edit: To clarify, imho these categories have been popular forever, because that's what every new indie dev thinks about first when they have a "great" idea. They're not necessarily tied to vibe coding and would've been released even without AI.

Okay, I was not familiar with the Postgres specific terminology.

Just for context, I run Postgres on an OpenBSD host (will probably be FreeBSD in the near future) to back an instance of davical which is a caldav server used by a total of two people.

I will keep tuning in mind if I ever actually use Postgres for anything significant but for now it seems like it would probably be wasted effort.

While I'd agree that Debian is boring, it still seems to me that Postgres isn't, even with this in place upgrade tooling. I still have to remember a specific upgrade command special to Postgres.

I just read this LinkedIn post and it made me pause — the point was that most startups wait until they land an enterprise deal to start thinking about SOC 2 or compliance… but by then, it’s usually too late. The author compared it to “learning the rules after the game starts,” and now I’m questioning whether we’re approaching this the wrong way.

We’re an early B2B SaaS company that just raised a small pre-seed round. Like many others, we’ve been telling ourselves we’ll worry about SOC 2 “once a big customer asks.” But now I’m wondering if that mindset is quietly keeping us out of conversations and deals we don’t even realize we’re missing.

For founders who’ve been through this:

-When did you actually start investing in SOC 2 or other frameworks (ISO, HIPAA, etc.)?

-How much did you spend, and did it feel worth it?

-Did it noticeably impact sales velocity or investor conversations?

-Is strong posture and documentation enough early on, or does certification itself matter?

Trying to figure out where the real inflection point is — when compliance stops being a distraction and starts being a growth lever. Would love to hear how you approached this and what you’d do differently.

If you want to get a single entry point into your repo's task, also consider my tool: dela[0]. It scans a variety of task file definitions like pyproject.toml, package.json, makefile, etc and makes them available on the cli via the bare name of the task. It has been very convenient for me so far on diverse repos, and the best part is that I didn't have to convince anyone else working on the repos to adjust the repos structure.

Dela doesn't currently support mise as a source of tasks, but I will happily implement it if there is demand. Currently [1] I saw mise use on 94 out of 100,000 most starred github repos.

Thank you for allowing this moment of self promotion.

Very much agreed. I think the dominance of the chat interface to LLMs has materially impaired the general usefulness of these tools — the sooner it goes away the better. It’s almost impossible to explain to a non-engineer how the illusion of a continuous conversation is crafted through context management and why past moments in a conversation might fall out of memory. My general advice to non-technical friends is to create a new conversation for each prompt so that they can get a more deterministic sense of how to formulate instructions and which are successful.

I was really hoping Apple would make some innovations on the UX side, but they certainly haven’t yet.

At the risk of being downvoted, the dating scene in america is terrible. Masculinity in western societies is heavily pathologized to the point that men who aren't 6ft and very good looking have the deck heavily stacked against them. I can't blame men for turning to AI girlfriends. I myself left the united states and couldn't be happier. There are plenty of countries where its easy to meet women and end up in a relationship. I'm back stateside atm visiting family atm and its only gotten worse as far as I can tell.

Rather: these companies consider it to be a really bad business idea to spend lots of billions for building a new state-of-the-art model that will be obsolete half a year later.

That's still much less than the aluminum from solid rockets, which have been ongoing since the 1970's. Per your own link,

> "In situ measurements showed evidence of a 1,000% increase in stratospheric aluminum levels from 1976 to 1984 (Zolensky et al., 1989), which was associated with the emission of hundreds of tons of such particles from solid rocket motors (SRM) during atmospheric ascent (Brady et al., 1994)"

If you follow Brady et al. (1994)[0], you'll read that every Space Shuttle launch (Table 1) deposited 112 tons of Al2O3 into the stratosphere (>15 km).

[0] https://apps.dtic.mil/sti/pdfs/ADA289852.pdf

This isn't a new phenomenon at all; in fact the peak alumina pollution from in the past (112 tons per STS launch) exceeds the worst-case future estimates from academic research (360 tons per year from satellite reentries).

(/meta Coincidentally, I once linked that exact Brady paper on HN, three years ago[1]. Actually, long before the current social media fad for being concerned about satellites. At the time I wrote, and this has truly aged well, "No one ever gave a shit").

The problem is not the limitations of the capabilities per se but their discoverability (https://en.wikipedia.org/wiki/Discoverability). The user doesn't know what the capabilities are, as they are added and -- infuriatingly -- removed. Google Assistant is a perfect example of this.

Buy OTM AMD call options before the deal and then book profit to cover part of the purchases.

Or company announces plan to buy Bitcoin, but doesn't actually do so. Buys call options before the announcement. Sells call options after the stock surges and uses proceeds and inflated stock to issue secondary offering to buy the Bitcoin, and buys puts before the secondary offering, also funding the BTC purchase. Stock returns to original price. Net result is free BTC.

There are tons of financial tricks by taking advantage of materially important news and the ability to 'create money out of thin air' by exploiting price swings.

Just had a quick look - while they have that self-hosting option, they still assume you will use a cloud LLM. I started digging because I got confused of them not mentioning any GPU when it comes to resource requirements. There is some documentation on using it fully self-hosted including the LLM, but the emphasis here is on "some".

To be clear: I am looking at this from a CEO perspective, not a "I will play with it in my spare time" nerd one.

Combining this with something like tangled.sh/bluesky's AT protocol or what forejo is working on in their activitypub federation integration can actually make it genuinely federated as well

Or maybe radicle as well if someone is okay with swapping in a custom software but the hiccups can be too much imo so tangled.sh is the most interesting thing to me right now

What is stopping something like gem.coop to exist with the at protocol/tangled.sh??

I bring this story up all the time. It's tragic that it was never implemented! I know you could read it as a story about CEO capriciousness, but to me it highlights how far Steve was willing to go to make the Mac playful and enjoyable. Back then, even the idea of dragging a file into a little trashcan was delightful.

Three years ago I was very skeptical of Ladybird. But two things have changed. First, they have funding for 8 full time engineers, which I definitely wasn’t expecting. Second, it’s been three years. So given that, I am more optimistic.

There’s still a very long way before they can compete with Chrome, of course. And I’m not sure I ever understood the value proposition compared to forking an existing engine.
