0xferruccio··on Playgrnd – tiny tools for making weird, beautiful things
this looks really good, very fun to play with too
0xferruccio··on Theranos.World
this site is so slick great job! love how the email in the iphone works
0xferruccio··on How Bluesky draws its logo on screenshots
To be fair this is useful for discovering bluesky from screenshots getting posted on other platforms.

Their product UI kind of looks like X, so it's helpful to know the source of a post

0xferruccio··on The zero-cost fallacy: open-source software in the agentic era
The irony of this article is that it reads with the annoying robotic cadence that makes me not want to read slop blogs

Sentences like "The licensing paradox: From freedom to exploitation" are starting to burn my eyes

0xferruccio··on Postgres rewritten in Rust, now passing 100% of the Postgres regression tests
Super impressive! Remember talking with Michael about his experience with Citus at Heap and reading his blog posts on Postgres

Super cool to see him working on this now, almost 10 years later

0xferruccio··on DuckDB Internals: Why Is DuckDB Fast? (Part 1)
We have a hook that runs on session start and session end that sends data to a lambda with a hard coded JWT token that we ship in the code

We added that to the managed settings for our Claude instance as a “base” plugin and provision it to all machines using JAMF

A non-enterprises version of that would be to add this hook in your main repository’s .claude folder

0xferruccio··on DuckDB Internals Part 1
DuckDB is amazing for any sort of fast data analysis when the data is small enough that it can fit on your laptop

Recently at work I've been using it to analyse the Claude code sessions of every engineer at our company (that we upload to S3) and it's been extremely helpful to help us find gaps in devex and have clear metrics to back up the impact of fixing them

Another thing it's been really useful for has been getting metrics on Claude skills usage and then dive into use-cases by looking at the transcripts

Other engineers that had never touched DuckDB were so impressed with how easy it is for AI agents to write queries on our dataset

0xferruccio··on Show HN: FablePool – pool money behind a prompt, and Fable builds it in public
This is a genius idea, I love it!!
0xferruccio··on Show HN: Superlog (YC P26) – Observability that installs itself and fixes bugs
Congrats on the launch, this looks very promising. I hadn't seen any installation that uses a URL to point to a skill, seems like an evolution of wizard scripts

That been said for more complex setups like on kubernetes where you need a collector and an operator I found OTEL to be super painful to setup a couple of years ago. Has it gotten any easier now?

0xferruccio··on Cursor Camp
Incredibly well done by Neal as usual!! Always has new fun experiments that are always completely new concepts
0xferruccio··on My eighth year as a bootstrapped founder
Great article as usual, got a flashback to reading your first post on here 8 years ago. At the time I was starting my career in tech by building small projects for fun and launching them on Product Hunt. Great to see you’re still going at it!
0xferruccio··on OpenAI's In-House Data Agent
At Amplitude we built Moda which is super similar to this.

Our chief engineer Wade gave an awesome demo to Claire Vo some months back here: https://www.youtube.com/watch?v=9Q9Yrj2RTkg

I use this basically every day asking all sorts of questions

0xferruccio··on Benchmarking OpenTelemetry: Can AI trace your failed login?
To be fair I remember spending almost two weeks implementing OTel at my startup, the infrastructure as code setup of getting collectors running within a kubernetes cluster using terraform was a nightmare two years ago.

I just kept running into issues, the docs were really poor and the configuration had endless options

0xferruccio··on New YC homepage
some of the design interactions are really polished. the section written with the quotes from founders is really cool. the hover effect with the before and after of the YC partners is a great touch too!
0xferruccio··on I was banned from Claude for scaffolding a Claude.md file?
to be fair at least half of the software engineers i know are facing some level of existential crisis when seeing how well claude code works, and what it means for their job in the long term

and these are people are not junior developers working on trivial apps

0xferruccio··on Superhuman AI Exfiltrates Emails
The primary exfiltration vector for LLMs is making network requests via images with sensitive data as parameters.

As Claude Code increasingly uses browser tools, we may need to move away from .env files to something encrypted, kind of like rails credentials, but without the secret key in the .env

0xferruccio··on Exe.dev
The clone idea sounds awesome! It’s kind of like what Devin does for setting up new machines for each task
0xferruccio··on Exe.dev
i tried this and it's pretty cool, that being said for my use case of spinning up many agents working on my app I'd need a way to specify the docker images that get started with each new VM

i cannot find a way in the docs to start new VMs with a bootstrap script that starts a bunch of services for me and runs a specific docker image

my use-case is that I want a full developer environment for every branch of my project, so i can vibe code on many VMs at a time

EDIT: Just realised there's an image one can pass to the new command. Still it's not clear to me whether private images would be supported and what registry this is using:

exe.dev ▶ help new

Command: new

Create a new VM

Options: --command container command: auto, none, or a custom command --env environment variable in KEY=VALUE format (can be specified multiple times) --image container image --json output in JSON format --name VM name (auto-generated if not specified) --no-email do not send email notification --prompt initial prompt to send to Shelley after VM creation (requires exeuntu image)

0xferruccio··on Launch HN: Phind 3 (YC S22) – Every answer is a mini-app
Congrats on the launch I love the idea! Super exciting to see these generative UIs

I tried to make it generate an explainer page and it created an unrelated page: https://www.phind.com/search/explain-to-me-how-dom-66e58f3f-...

0xferruccio··on Show HN: Free Geo (SEO for LLM)
Our core product is an analytics product that lives on people's website, so we're able to tell what are the main pages that people are reaching with LLMs

For our in-app AI visibility product we use that information for finding prompts at topics that are being used to reach those pages

For this public tool instead we do a best guess of what are reasonable queries companies would want to show up for and run them against Google and ChatGPT

0xferruccio··on Show HN: Free Geo (SEO for LLM)
Hey there Ferruccio here, I worked on this launch for the past month since joining Amplitude

We built this tool because we’re seeing that LLMs are becoming the main way people compare brands when making buying decisions, even before visiting your site

I’d love to get feedback from the HN community on this.

If you want to skip the video explainer you can generate a report directly by typing in your brand here: https://amplitude.com/try-ai-visibility (no email required, it just takes 5 minutes to generate)

0xferruccio··on SQLite offline sync for Android quick start
Looks really cool! Congrats on the launch
0xferruccio··on Sidekick: Local-first native macOS LLM app
Really cool! I hope they'll roll out MCP support so that we can add support for it in our MCP app store (https://github.com/fleuristes/fleur)

Right now only code editors and Claude support MCPs, but we'd love to see more clients like Sidekick

0xferruccio··on Show HN: Open-source app store for Claude
One of the makers here - it was really fun to build this

While things seem to be still very early and each tool call needs to be manually approved in Claude, using these MCPs for some of our non developer friends was mind blowing

I think while it's still unclear what the winning way to build these integrations between apps and LLMs will be we need early experiments like this one for people to understand what's possible

0xferruccio··on Ghostwriter – use the reMarkable2 as an interface to vision-LLMs
IMO the easiest way to play around is to use the reverse engineered APIs

https://github.com/erikbrinkman/rmapi-js

0xferruccio··on Ghostwriter – use the reMarkable2 as an interface to vision-LLMs
I think the thing I really didn't like was the lack of an OAuth like flow with fine-grained permissions

Basically authentication with devices is "all-access" or "no-access". I would've liked it if a "write-only" or "add-only" api permission scope existed

0xferruccio··on Ghostwriter – use the reMarkable2 as an interface to vision-LLMs
This is so cool! I love to see people hacking together apps for the reMarkable tablet

I made a little app for reMarkable too and I shared it here some time back: https://digest.ferrucc.io/

0xferruccio··on Using 2 Editors Because Xcode Is Dumb
XCode is so bad - Makes me not want to build iOS apps. If Apple swallowed some of their pride and just focused on providing a great developer experience via extensions for the editors people already use like VS Code and Vim IMO every developer would be thankful
0xferruccio··on Bun 1.2 Is Released
I love the direction, especially including s3 and Postgres support natively - it makes a ton of sense for this to exist as an alternative to the “build your own framework” status quo

This is the standard in every web framework like Rails and Laravel, and the JS ecosystem will really benefit from this. The next steps are migration and schema management and a better out of the box testing story (w/ nice way to setup factories)

0xferruccio··on Show HN: A daily digest for reMarkable
Thanks for the kind words! I completely understand your concerns about data security - it's exactly the kind of thoughtful consideration I was hoping users would have.

I'm actually considering open sourcing the entire project, which would allow security-conscious users like yourself to self-host the service. Alternatively I could also build a "self-hostable reMarkable gateway" that could issue write-only tokens, though this would require some architectural changes.

Regarding the browser extensions - unfortunately those wouldn't work for my use case since they require the user's browser to be running to execute any actions. The service needs to be able to run on its own schedule.

I don't have a Patreon set up, but your offer of support means a lot! The best way to help right now would be to probably support the development of building a more privacy focused integration once I open source the app sometime over the weekend
