An AI slop pattern so widespread it’s now referred to as “it’s not pee pee it’s poo poo”.

Show HN: `seven up` is `vagrant up` made of sprite (Fly.io) for safe vibe-coding

mtremsal — Fri, 06 Feb 2026 14:42:18 +0000

Agentic coding (CC/Codex/Cursor/etc.) works best when the assistant can autonomously "close the loop", i.e. with shell access, a browser skill and full permissions (e.g. --dangerously-skip-permissions).

The naive approach of running it locally creates massive risk, both adversarial ("lethal trifecta") and accidental (rm -fr ~/). Since the agent needs to run dependencies and Docker-in-Docker remains a nightmare, it's natural to consider the decade-old `vagrant up` workflow based on local VMs for isolation and disk snapshots. See for example Emil Burzo's "Running Claude Code dangerously (safely)", on HN not even a month ago. However in 2026 paying the overhead of local VMs, especially on ARM CPUs, feels terrible.

Enter fly.io's sprite backend: https://docs.sprites.dev/. In my (admittedly short) experience, sprites give me the best of all worlds — hardware‑isolated microVMs with fast startup, persistent disks, and checkpoint/restore — so I can keep a Vagrant‑style workflow without the VM overhead. As an added benefit, reduced latency to inference APIs makes the whole experience feel snappier.

This CLI tool provides me with a familiar command: `seven up` mirrors the old‑school `vagrant up` workflow, but is "made of sprite". Get it?

Thank you, this was excellent! From McMansions, to F1, to eroticism the author has quite the range!

If you mean the "consumer ecosystem", then Gemini 3 should be available as an API through Google's AI Vertex platform. If you don't even want a Google Cloud account, then I think the answer is no unless they announce a partnership with an inference cloud like cerebras.

Then white plays 1 stone, capturing all the black stones at once, essentially resetting the game with a 360 points lead.

(black goes first, white has Komi, so really a 260+komi points lead)

I was wrong. They’re attaching the fee to the lottery, somehow.

IIRC technically there's no such thing as a "renewal". It's just a new application that bypasses the lottery. So given the low level of thought that goes into these EOs, the answer is almost certainly "yes"...

New comment by mtremsal in "The European public DNS that makes your Internet safer"

mtremsal — Fri, 13 Jun 2025 13:19:47 +0000

This is neat. I wonder what the delta is between this and NextDNS (who funds/powers the non-profit). I imagine NextDNS blocks a superset of the baseline of dangerous domains blocked by dns0.eu? Is the main addition primarily advertising and analytics related?

edit: another key addition by NextDNS is a global infra footprint, rather than just in the EU. Oh it looks like there’s no anycast with the non-profit as well? And you have to pick your local resolver. I guess that makes sense because the main value prop of NextDNS (to me) is when I’m traveling and a local pi-hole won’t suffice.

Comment from `amanchanda`, i.e. the OP.

Nice hustle writing an Ask HN post to then plug your own product, but you have to make sure to respond to questions with your _other_ account `nicooo`. ;)

Many EU countries have done the same in recent weeks. This is less about putting diplomatic pressure, and more about warning people to avoid traveling to the US due to real danger.

New comment by mtremsal in "The Road Not Taken Is Guaranteed Minimum Income"

mtremsal — Fri, 21 Mar 2025 15:53:33 +0000

IIRC Piketty's book also made a similar suggestion of having the government as an employer of last resort, i.e. offering an unlimited number of jobs at a guaranteed minimum income. It's seen as a more "palatable" policy by many, as it's "just a job" and we've already tried something similar during the New Deal. For people who take these jobs, there's also a lot less stigma than "taking social security".

New comment by mtremsal in "There Was a Texas Lottery Arbitrage"

mtremsal — Wed, 05 Mar 2025 19:32:30 +0000

IIRC the remaining risk lies in multiple people winning or attempting arbitrage simultaneously, thus dividing the expected revenue by the number of winners. So not a free lunch.

Good news, you now have time to pick up The Bazaar instead! (joke aside, it's quite fun, a lot more chill, and not nearly as exploitative as Hearthstone)

My first thought exactly! I have never heard of Malört outside of the cryptography/security industry, where offering it is seemingly used as a hazing ritual.

Would you mind expanding on how SerDes become a bottleneck? I’m not familiar and reading the Wikipedia article wasn’t enough to connect the dots.

It has become more popular as a result of Google Search algorithm changes in December 2023. Search results now tend to showcase relevant Reddit posts regardless of subreddit size or post popularity, so it’s an efficient way to beat the SEO game. There’s value in owning the subreddit itself, such as to be able to display sidemenu links of your choosing.

> Anyone know why a business would choose to only accept credit not debit cards?

Maybe they want to place a temporary charge to verify the card's valid? I don't believe you can do so with a debit card.

New comment by mtremsal in "Workbook for Technical B2B Products"

mtremsal — Tue, 16 Jul 2024 17:59:32 +0000

I use this workbook as part of my product and GTM advisory work with technical founders working on B2B products (e.g. devtools, infra, security).

There's something unique about deeply technical products, and startups founded by engineers, that often lead them to similar challenges. There's also a unique requirement that engineers must shape the product at least as much as PMs, however technical they might be. While there's no silver bullet in my doc, there's some opinionated advice to avoid common pitfalls at various stages.

I'm not looking for new customers; I just figured that some technical founders or PMs out there might find the doc useful while navigating their own 0-to-1 journey. Cheers!
