Resume: https://www.linkedin.com/in/francis-stephens/
Email: francisstephens@gmail.com

I work primarily on backend systems, with a strong focus on performance and system stability/resilience. I worked as a performance engineer at the mobile add-attribution company Adjust.

Some interesting open-source projects include

https://github.com/fmstephe/memorymanager
An exploratory manual memory allocator for building large in-memory data structures with near zero GC cost.

https://github.com/fmstephe/matching_engine
A financial trading matching engine with a somewhat novel red+black tree implementation.

https://github.com/fmstephe/flib
A set of packages primarily in support of a lock-free single-producer single-consumer queue.

My ideal position would be working on backend systems primarily in Go.

I'm talking about the modern rationale, not the historical one.

It's not like we forgot to change back. It's that we decided we really liked the longer usable daylight in the summer. There have been tons of adjustments to DST since WWII, reflecting the fact that we like it in the summer, and have variously adjusted which months it covers.

The point is, it is literally described as saving daylight, which is what I explained. Saving it from the morning to use in the evening.

krea.ai | Senior Backend Engineer | San Francisco, CA | ONSITE | https://www.krea.ai

krea does AI research & builds AI tools for image generation, video generation, node-based workflows, LoRA training, and more. Small, mostly in-person team with a view of Alcatraz from the office window. Our users range from hobbyists all the way to professional designers at Apple or architects at firms behind The World Trade Center or Burj Khalifa.

We're looking for senior backend engineers. You'd work across our SvelteKit app (Postgres, Redis, Docker, ClickHouse), Python ML inference on GPU clusters, and k8s clusters across multiple cloud and GPU providers.

Some recent projects:

- building canary deploys with cookie-sticky traffic splitting
- implementing durable execution for long-running workflows
- designing our public API with OpenAPI docs auto-generated from Zod schemas
- implementing enterprise-grade authentication, authorization, and permissions
- optimizing ML inference for our hosted image generation models

We care way more about first-principles and core engineering skills rather than specific shenanigans around programming languages or particular tooling—knowing a lot about old UNIX principles is a plus though.

You should be comfortable owning things end-to-end. Experience with GPU infra is a plus. Many of us have some kind of creative background, it helps when building tools for creatives but is not a requirement by any means.

To apply, email d+hn@krea.ai (use the +hn suffix to make sure your email is prioritized!)

I know half the point of OpenClaw is to let it run wild on your personal data so it can do anything, but, if you're looking for a secure but still capable AI agent/assistant, I built one I really like:

https://github.com/skorokithakis/stavrobot

Everything is sandboxed and plugins have fine-grained permissions, so you can tweak the security/usability tradeoff to your liking. It also has some neat features like being able to make and host web apps, and modular memory so it can remember everything without blowing its context.

100s of donors were stiffed of greater than half the money they put into their crowdfunding for the phones, and the jolla folks were all like 'be happy we gave you any back' and then went on to pour the investors' money into other failed projects.

I really want to make a fake PSA that suggests anyone wearing the Meta glasses is probably a pervert and should be proactively avoided/shunned.

This product cannot be allowed to exist in the type of world I want to live in.

The power structure wants these to succeed in the market for so many horrific reasons and it will require some serious societal muscle to reject them.

"A computer that was so simple and so predictable."

This is what cachyOS + KDE is giving me at the moment. Ok, so it's not totally simple and there are A LOT of updates. But it's by and large predictable. I never had a 1980-90s Mac, but I had an Apple IIe and an Amiga 500. While cachyOS is so much more powerful it doesn't abuse that power like Windows and OSX with so many background processes and telemetry. I have a Mac laptop and I dual boot my PC with Windows + Linux. I don't have hate OSX but CachyOS + KDE is by far my favourite as it's customisable to the extent I want and it just gets out of my way. Highly recommend it if that wasn't obvious!

You're right that most of these signals are spoofable in isolation. FCaptcha doesn't make pass/fail decisions on any single signal. It's weighted ensemble scoring across ~50 signals, where the cost of spoofing all of them simultaneously is the actual defense.

Addressing a few specific ones:

PoW CPU cost: Difficulty is adaptive — 4 for residential IPs, 6+ for datacenter. On modern hardware that's ~200-800ms. For 1M users/day that's ~55-220 CPU-hours total, distributed across clients. It's comparable to what Cloudflare Turnstile does.

Keyboard-only users: Already handled. If keyEvents >= 2 and totalPoints === 0 (tabbed + Enter/Space), all mouse-based detections are skipped. No false positives on keyboard users.

"Can be recorded/replayed": signals are SHA-256 hashed and bound into the PoW input before solving. You can't solve PoW first then attach recorded signals... the hash won't match. Replaying old signal sets also fails because each challenge has a unique nonce.

Micro-tremor at 125Hz: Fair point... low polling rate mice produce less granular data. It's weighted low and only contributes when data is available. Not a gatekeeper.

CDP userGesture: true: Good catch. We detect CDP-specific artifacts (Runtime.evaluate residue, protocol binding flags), but you're right that a custom Chromium build sidesteps this entirely.

The honest answer: a sufficiently motivated attacker with a custom Chromium build can beat this. The goal is to make that cost high enough that it's cheaper to just solve the CAPTCHA legitimately or move to an easier target. Same tradeoff Cloudflare makes, but open source and privacy first.

Where I think the real gap is: server-side signals (IP reputation, TLS fingerprinting, rate patterns) and that's really what our paid bot detection is for. https://webdecoy.com

I dived into a niche world of small phones recently while looking for replacement to malfunctioning Pixel 4a (which is apparently now considered compact phone). There's a few small manufacturers in China making some, with 4 inch or 5 inch screen, like Aiphor or Unihertz. And by "small" I mean "they use kickstarter to fund their R&D" small.

Other than that... Nobody's really bothering with compact phones anymore, in the US or in the rest of the world. Bummer.

I'm convinced that this is the fate of all successful software companies. It's not a result of arrogance or hubris or anything else like that. It's the result of turnover.

Take your favourite rock band and turn over all the musicians until no one is left from the original band. Should we expect the band to continue cranking out chart-topping hits?

There's one further factor that makes the situation even worse than the "Rock Band of Theseus." That's the fact that young software engineers are not interested in stewardship. They want to build their own projects, not fix bugs in someone else's. Across the software industry we see this lead to a continual churn, rewrites and redesigns no one wants, and a huge amount of wasted effort reinventing the wheel (and often making a worse wheel).

I hired some people to come do some work at my house. One of them was wearing Meta glasses. He said he got them so he could keep both his hands free while crawling around in an attic or wherever, and getting video of what they were inspecting to document the work to be done.

It’s possible that even if all your friends/family would stay far away, they could still end up in your proximity.

No argument from me about opera. The music is often fabulous but the “acting” is histrionic, the plots are generally overwrought, and the singing is like watching the 400th lap of the Indy 500. First two laps were kind of cool but now we’re in the fourth act and why can’t this tenor stop yelling?

But I don’t have any guilt about my displeasure. I’m a snob about some things, a reverse snob about other things, and some things I just like or dislike for whatever reason.

Some people wrap a lot of their social identity up in passing an invisible bar in the level or type of interests they hold.

This is brain damage levels of decision-making.

If you live in a portion of the US that has severe weather, a NOAA weather radio with the EAS alerting function is a mandatory addition to your home. It could be the difference between life or death. See: first five minutes of Twister.

Inexpensive, AC powered with battery backup and it always works. No internet, no cell tower needed, which was likely just trashed by the storm you're trying to shelter from.

Fun fact these radios can warn you about more than weather. "Radiological Hazard Warning" and "Volcano Warning" to name a few.

Many more people died in decades past from severe weather and natural disasters precisely because of inadequate advance warning.

So naturally they would migrate people to...a replacement orders of magnitude more unreliable.
Show HN: A Crop Value Calculator for Garden Horizons
by kristoff0601 | 2026-03-03 03:10:51+00:00
Hi HN — I built something that’s been genuinely useful for myself and other Garden Horizons players, and I’d love to get feedback.

Website: https://gardenhorizonscalculator.co/

Garden Horizons (a popular Roblox farming game) has a deceptively complex economy — crops have weight-scaled pricing, ripening multipliers, color variants, and mutation effects from weather. Figuring out the actual sell value of a harvest has historically required spreadsheets or manual math to estimate.

What I needed was a tool to instantly compute the sell value and profit for any crop setup before I actually sell, so I built one.

What it does

Takes crop type, weight, ripeness state, variant, and weather mutation data

Calculates exact sell price in Shillings

Helps optimize when to harvest and which crops to plant for best profit

Runs entirely in the browser — no sign-ups, no tracking

The goal was not just a lookup chart, but an interactive calculator that helps you compare scenarios quickly without manual spreadsheets.

Looking for feedback

I’m curious about:

Whether others find this useful

Any edge cases I haven’t covered

Suggestions for UI or expanded functionality

Happy to answer questions. Thanks!
Show HN: CSV Analyzer – drag-and-drop data analysis with AI insights
by atdl | 2026-03-03 03:11:51+00:00
I shipped my first product yesterday after years of not finishing anything

I'll be honest — I've been wanting to build something of my own for years. I'm a senior manager in analytics, and I've never shipped a single side project.

Yesterday I sat down and didn't get up until something was live. I built a CSV analyzer — you upload a CSV file and it instantly gives you statistics, interactive charts, and AI-powered insights that explain your data in plain English.

Stack: Next.js, Anthropic API, Stripe, Vercel.

Pricing: Free for files under 500 rows. $2.99 one-time for a single AI analysis. $9/mo for unlimited.

It's not perfect. But it's live and that's a first for me.

I'd love feedback from this community. What's missing? What would you change about the pricing? How did you get your first users?

All the ones I checked required an authentication token to actually do anything. Which makes me feel a bit better about this site.

Is it typical or even possible to configure OpenClaw in another way? Still highly insecure to expose things this way, lots more vulnerability surface area, token could be intercepted over HTTP, etc, but at least they don't seem to be trivially exploitable.
by fc417fc802 | 2026-03-03 03:12:14+00:00
I'd caution not to lump all fans together as a single group. The internet in general (or perhaps more accurately the world as a whole) has plenty of absolutely awful people with seemingly nothing better to do than pointlessly harass others.

Anime fans can be a bit ridiculous but at the same time some of them accomplish impressive things. They've pushed AV1 (and other) encoders forward substantially. A number of older shows that were never going to get a remaster have been made much more pleasant to watch thanks to downright obsessive restoration efforts. They've also salvaged at least a few horrendous remasters that would otherwise have never been fixed.

Amusingly they're responsible for the propagation of the leaked DCP versions of several titles despite the fact that even most fairly high end devices aren't capable of playing such videos back due to the hardware being insufficient.

I still find it hilarious that of all things people pirating cartoons in their free time ended up driving a significant amount of codec tooling development. I wonder how you'd calculate the broader net economic impact of such an outcome.
by beloch | 2026-03-03 03:12:36+00:00
The breakdown probably varies according to the time of day. In the middle of the night (for North America) I'd expect to see a higher proportion of international users, although I'd also expect the numbers aren't quite so high since HN is U.S.-centric and predominantly English only.

The number of Canadians is relatively easy to estimate though, since the geographic distribution is similar and the majority do speak English. I'd expect a roughly 8.5:1 ratio of Americans to Canadians based solely on population.

I'm puzzled by this conversation, because Amazon did get on the agent bandwagon with Alexa Plus (I have it, it's buggier than regular Alexa and it's all making me throw my Echos away since they can't even play Spotify reliably).

Also, my Alexa does advertise stuff to me when I talk to it. It's not Budweiser, but it'll try to upsell me on Amazon services all the time.

My plan for this in my current toy language project is to allow things like 'import * from Foo', but save a package.lock esque file somewhere on first build - after that you need to run some kind of '--update' command to bring in totally new names.

The problem I'm trying to solve is more around ensuring that purely additive changes in libraries aren't technically breaking due to the risk of name clashes than general discoverability though.

Sometimes I just want to open a project quickly and take a look without getting all dependencies installed and the lsp working and so on. Sometimes I want to look at another team’s project even though it’s in another language than my team works in, but I don’t want to set up that language in my environment.

This is particularly true with cpp projects, where wrestling with cmake and co just isn’t how i want to spend my time to answer a question about why something is slow or what a serialized object shape should be under various circumstances.
by v_CodeSentinal | 2026-03-03 03:14:18+00:00
Nothing super fancy.
For me “proof” just means the agent has to make its intent explicit in a way I can check before running it.

For example:
1) If it wants to delete a file, it has to output the exact path it thinks it’s deleting. I normalize it and make sure it’s inside the project root. If not, I block it.
2) If it proposes a big change, I require a diff first instead of letting it execute directly.
3) After code changes, I run tests or at least a lint/type check before accepting it.

So it’s less about formal proofs and more about forcing the agent to surface assumptions in a structured way, then verifying those assumptions mechanically.

Still hacky, but it reduced the “creative workaround” behavior a lot.

Tablets will need to become a great deal lighter than they currently are before the awkwardness you describe will dissipate. Maybe after some kind of breakthrough in battery tech that allows for a much lighter and thinner battery?

Until then, I would agree that the old 12" MacBook still has a big leg up over an iPad + keyboard due to its clamshell form factor. It's so much less fussy for any use case where a keyboard matters.
Show HN: Paranoid Qrypto Offline/air-gapped/encryption(Argon2id+AES-256-GCM)
by ParanoidQrypto | 2026-03-03 03:15:21+00:00
Built an offline encryption tool for people who don't trust cloud services or hardware wallets.

Paranoid Qrypto runs completely offline (air-gapped). You type your seed phrase on an offline device, and it encrypts it using Argon2id + AES-256-GCM. The encrypted file can be stored anywhere USB, cloud, printed as QR code without exposing your keys.

Why this was build:
Hardware wallets cost $100-200 and are single points of failure
* Cloud solutions require trusting a third party
* Paper backups have no protection if found

Technical details:
* Runs in browser with no server calls
* All encryption happens locally
* Open source tools on GitHub: integrity-auditor, airgap-bridges (BTC/ETH/XRP)
* Three tiers: Essential ($99), Advanced ($199), Ultimate ($299)

Seeking Advice on Crypto Recovery Through Digital Asset Forensics
by Mikechristian | 2026-03-03 03:15:21+00:00
Hello everyone,

I hope you’re all doing well.

I’m reaching out to ask for guidance regarding a crypto recovery situation my family and I are currently facing. We are exploring the possibility of using digital asset forensics to help trace and recover crypto funds that were unfortunately lost/transferred under unclear circumstances.

A few specifics:

The transactions were made on Ethereum/Binance Smart Chain (or insert relevant chains)

We do have the wallet addresses and transaction history

We do not have direct access to the private keys

We are not entirely sure where the funds ended up

Before committing to any service, I wanted to gather insights from this community on:

What reputable digital asset forensics providers are trusted by members here?

Any recommendations on what documentation they usually require?

What red flags to watch out for in crypto recovery services?

Realistic expectations on timeline and success rates?

I’m aware that recovery isn’t guaranteed, but I want to ensure I pursue this in the most informed and safe way possible, avoiding scammers and false promises.

Any feedback, experience, or resources you can share would be greatly appreciated.

Thank you!

When was the last time you walked into Best Buy, had a real question, and immediately found someone who could help you make the right decision?

Exactly...

Shopping for tech today usually means standing in the aisle researching on your phone, opening 12 tabs, reading endless reviews, maybe going home, watching comparison videos, and still wondering if you missed something or overpaid. So I built Rectangle.

Rectangle is an AI shopping agent for consumer electronics. It compares prices across multiple retailers, recommends hardware based on your actual needs, answers compatibility questions, and most powerfully lets you check out from multiple retailers in just ONE cart.

No guessing. No tab hopping. No multiple checkouts. No endless review reading. Just clarity before you buy.

Everything in one cart, and one checkout.

If you are planning to purchase tech soon, I would genuinely value your feedback. If you just want to play around with it, its free to use. I am building this in public and refining it based on real users. You can contact me directly for any questions/concerns.

I think you're arguing with a point I didn't make. I'm not excusing anyone. I'm describing a mechanism in response to "I cannot comprehend why." Here, why people stay in situations they might privately find distasteful. That's a different project than assigning moral grades.

"They have a choice" is of course literally true. It's also not very interesting? Everyone always has a choice in the tautological sense. The question the parent raised was how do people live with it, and the answer is: the same way people live with all kinds of things. Incrementally, surrounded by context that makes it feel normal, with stakes that feel high relative to their baseline, not yours.

Your 99.9999% stat kind of makes my point for me. Those people also didn't get a $400k offer from Meta. The trap isn't marriage+kids, it's young + don't know better + land there + marriage + kids+a lifestyle calibrated to a specific income, plus the identity that comes with it. The golden handcuffs thing is a cliché because it's real.

None of this is a defense of working on things you find unconscionable. It's just that "they could simply choose not to" has never once in history been a sufficient explanation of human behavior.
