this site is a hoot
sentrysapper··on Show HN: Make your bookmarks smarter with AI
I don't understand who this is for.

From the screenshots, it's almost as if it was designed to keep someone inside an echo chamber and not come up with any original ideas about what they've read or bookmarked.

sentrysapper··on Ask HN: What are you working on? (March 2025)
I started building a MtG competitor inspired by Altered and Netrunner. As weird as it sounds, I started with some bash scripts to see how the meta would play out to make sure the card values/strategies were balanced.

I would love to compare game development notes if you're interested in discussing this sometime.

sentrysapper··on Ask HN: What are you working on? (March 2025)
Email Sanitization Service based on Dangerzone.

1. User on allow list forwards suspicious email to service directly from their inbox. 2. The email is parsed, opened, and sanitized in a sandbox environment. Attachments are scanned into raw pixel data and then converted to PDF. 3. Reply email with sanitized content is sent back to original sender. 4. Server is rebuilt, forgetting all previous jobs to protect privacy.

sentrysapper··on 'Hey Number 17 '
I wonder if Kushal Mohta and Vivaan Baid have ever read the story of the Brazen Bull.
sentrysapper··on Anyone can push updates to the doge.gov website
in Seeds Of Terror by Gretchen Peters points out those subsidies helped farmers NOT farm opium for the Taliban. If you think of it from an Afghani farmer's perspective: why would you farm any other crop that pays significantly less per yield when you have a family to feed?
sentrysapper··on Ask HN: Where to Work After 40?
Business coaching. I'm sure you learned a lot in your startup journey. You could help others avoid the pitfalls you experienced.
sentrysapper··on Denmark will plant 1B trees and convert 10% of farmland into forest
IIRC in Ministry for the Future it was 50% of all land was reserved. 10% is a good start though for conservation efforts.
sentrysapper··on Ask HN: Who is pretending to be hiring?
I'm not affiliated with them but ghostjobs.io is doing awesome work tracking companies that do this.

For the job seekers on HN, avoid companies that engage in this behavior.

sentrysapper··on Medieval
I'm not sure you can get a functional Nord Piano for $300
sentrysapper··on Unconditional Cash Study: first findings available
I'd say that's intrinsically good. What is the alternative to not being able to afford the cost of living?
sentrysapper··on Security is not part of most people's jobs
Huh, never really thought about it this way. There really is no carrot to implementing secure solutions, only the stick when there is an incident.
sentrysapper··on Spotify won't open-source Car Thing, but starts refund process
As someone that doesn't own, but rents cars for errands, the Car Thing made perfect sense. Instead of spending several minutes trying to find a good station or pair my phone, which wasn't always an option, I could pop that in a vent and start jamming.
sentrysapper··on NSA Ghidra open-source reverse engineering framework
Perhaps, I've just never seen Ghidra used like this. For me, the clever part was putting together that the password generator method used time. Then putting together a wrapper app to batch produce passwords from the timeframe the client would have generated the passwords.
sentrysapper··on NSA Ghidra open-source reverse engineering framework
Joe Grand's latest video shows a clever usage of Ghidra to understand insecure password generator methods and recover lost BTC. https://youtu.be/o5IySpAkThg?si=EGhF7Jf01G6nQPL9
sentrysapper··on NSA Ghidra open-source reverse engineering framework
Yesterday Joe Grand put up a video explaining how he used Ghidra to find the password generator pattern and helped someone recover 43 BTC. For some folks, that was probably their first time seeing Ghidra in action and I imagine it sparked the curiosity flame again.
sentrysapper··on The Curse of Monkey Island
I loved this game growing up, but never got around to finishing it. I've been going back and playing point & click adventures like Grim Fandango and Broke Age. IMO that genre didn't age well. So many interactions are counterintuitive and I inevitably feel like I have to read a guide in order to proceed with the narrative.
sentrysapper··on What is Webb observing now?
This is amazing. I navigated back to some previous targets and saw what looks like some kind of astronomical event, blue clusters lining up to some kind of explosion. Can anyone explain what Webb is seeing to the left of its target here?

sentrysapper··on An open source initiative to share and compare heat pump performance data
Can I ask what model did you get and what part of Canada are you in?

More to the point, I'm looking for a recommendation for a smaller unit to heat 750 sq ft. in Quebec.

sentrysapper··on AI-generated sad girl with piano performs the text of the MIT License
I chuckled at gone "live", but otherwise that was pretty good code poetry. Thanks for that.
sentrysapper··on Deadweight Loss as a Service
I hadn't noticed that before but you're right, YT has ruined Rickrolling.
sentrysapper··on Starship Integrated Flight Test 2 at 7 Am Central Time
"The super booster experienced a rapid unscheduled disassembly".

Neat phrase for the booster explosion in the mesosphere.

sentrysapper··on Show HN: Scorecard.gg – minimalist scoring tool for your favorite board games
I like minimalist utility sites like this. Will try this out on my next game of Parks.

FYI looks like icons for first player and season bonus aren't available on the Parks scorecard. https://scorecard.gg/games/parks/

sentrysapper··on Track HN: Survival Rate of Show HN Stories
https://harvestsignal.com/ is also still alive, but the site certificate expired.
sentrysapper··on Lessons from Washington State’s New Capital Gains Tax
It's only 7% and for gains above $250K. I shouldn't be, but I'm shocked they had to defend this initiative.

For contrast, in Canada, capital gains tax rate is 50%, regardless of the amount.

sentrysapper··on Using ChatGPT to generate a GPT project end-to-end
Why the random forgetfulness?
sentrysapper··on Baker's Math (2009)
As in it goes against the designed usage (where total is 100%), but it still works.

The total ingredients being 170% can be found confusing initially. I'm glad the author provided more context and the example of a 500g flour recipe.

sentrysapper··on Ask HN: Have you taken action regarding the Uber hack?
HN thread on the latest Uber hack for those in need of context: https://news.ycombinator.com/item?id=32860728
sentrysapper··on San Francisco decriminalizes psychedelics
While a bit dry at times, there is a fascinating history on the use and misuse of LSD and psychedelics in Michael Pollan's "How To Change Your Mind."

In it he describes how Sandoz knew LSD had potential, they just couldn't figure out how to best apply it to human psychology. So they would literally give it out to anyone who asked for it.

Would recommend it to those looking to learn more about how it got criminalized in the first place. None of the comments I've read so far capture the full picture.
