zan··on How to Write with an LLM
Thank you for writing this.

This is gold

> Rule Number One: You may not use a single word an LLM suggests to you.

Over the last week-ish I turned around 2 product announcement blogposts within ~24hrs. Both written manually by someone who doesn't do product marketing for a living. It actually felt incredibly satisfying to focus and smash something out that was 100% human (despite praising the benefits of agentic systems, oh the irony).

My flow has been: Go for a walk, record all of the thoughts on the topic with speech to text, and have LLM organise my thoughts into what I call "facts" - simple sentences of fact, and point out open questions and inconsistencies ("you are a product marketing expert helping me organise the content for an upcoming feature announcement" ...).

After some back and forth of inconsistency bashing I have a large pile of short sentences in the vein of "Feature X is for Y because Z", that I use to manually build a narrative with headings, and then write the actual copy covering a subset of them.

I also agree that light style LLM edits are fine, and that I don't let LLM do anything other than ordering and filler words removal and provide structural comments.

zan··on Show HN: Geo Racers – Race from London to Tokyo on a single bus pass
I spent way too much time on this yesterday! Love it but it's super tricky. I'd love a (realistic) "cheat" that lets me see the departure boards without being at the station - that way you can plan the journey at least a little upfront. I'd do that on my phone anyway
zan··on Ask HN: What are you working on? (February 2026)
I'm a solo dev founder working on Potniq (https://potniq.com) - a business travel tool that tells you exactly when to leave based on your entire itinerary.

I used to work in devrel, and traveled a lot for events, and I always struggled skipping things like workouts, looking at the time on the last day of a conference trying to check whether it's time to leave yet - so this gives me the opportunity to build a tool I would have loved to use.

Currently I'm working on a LLM-powered booking email parser, that ingests forwarded booking confirmations and adds flights, hotels, etc. to your itinerary.

zan··on Ask HN: What Are You Working On? (December 2025)
https://potniq.com

It's a travel tool for business travelers that figures out your suggested departure times for your entire itinerary based on predicted traffic patterns. Think Flighty but for all the non-flight parts of your trip.

You first build a travel itinerary with your legs - flights, activities, hotels (and hotel returns) and it tells you things like "leave your hotel at 7:40am" before your 8:30 meeting - in a single itinerary, no need to do the google maps acrobatics for every two items in your itinerary. While it's aimed at frequent business travellers I personally use it for all family leisure travel and daily itineraries around town as well - "do I have time for lunch at home after my son's class or should we bring packed lunch". I built it as during my time working in developer relations I traveled a lot, and always built unnecessary buffers and kept nervously glancing at my watch or phone to see if my planned time to leave still holds.

Tech-wise, currently it's Remix web app with a NodeJS/Fastify backend and Supabase for storage, and relying on google maps for route duration calculations. I want to expand it to native mobile clients in the future as well.

I am using it as playground on product thinking, ruthless prioritisation based on user benefit, figuring out unit pricing and economics, sensible architectural design, and exploring how including AI-enhanced features here and there can help make the product better, not just include them for their own sake.

zan··on Looking for some developers to help user test our ML platform
The TL;DR; is in the next few days, 1 hour session, going through the docs & guides, and giving your experience. Conducted over Zoom and recorded.

We can offer a $50 Amazon gift card as a thank you.

Happy to also answer any questions.

This is great, thank you for sharing.

I recently created this one to help with my particular GitHub workflow - instantly diff any commit with the current master branch: https://gist.github.com/zmarkan/503789d31acf385e44f13b0b3c3c...

zan··on Technology that changed air travel
Just the level of airplane nerdery one needs right now. Also probably the best explanation of EDIFACT artifacts I've seen.

I just have one remark - how on earth does a 737 fly from SFO to LHR without stopping as in the example?

I love the ASCII arty Clippy for tool tips!

Hey everyone, I'm Zan - the person being interviewed. Any questions about the survey, let me know :)
zan··on The dots do matter: how to scam a Gmail user
There are more ways to resolve this.

- Netflix shouldn't charge cards without verifying email addresses. Security should be an integral part of UX, and not subservient to it.

- Individual email address canonicalisation/resolve _could_ actually be a standard. I'm not sure whether it is or not, but if we can agree on emoji we could also maybe agree on something that binds the internet together. Email is infrastructure, Netflix is not.

- There is still a potential issue by having configured catch-all email addresses on some domains, but we should in that case optimise for the hundreds of millions of gmail.

zan··on EU wants to require platforms to filter uploaded content, including code
Frankly this title is worthy of the Daily Mail. I expected more of GitHub. It merely describes one individual proposal currently going through the process of consultation before being debated in the parliament, nothing else.

There's also brave, which is supposed to be blocking ads as well. (haven't tried it personally though) https://play.google.com/store/apps/details?id=com.linkbubble...

Thanks guys, I'll collect these thoughts and add them to the blogpost. After all, I want this to be available to all and every one of us!
zan··on Know Your Tools – Terminal and Bash
knowing my demographic, that's what they prefer. If anyone wants to use vim, I point them to the vim person.

haha exactly! :)
zan··on Supersonic: New UI Hybrid Framework – Ionic, AngularJS, Cordova
"FUTURE-PROOFED FOR IOS & ANDROID When you use Supersonic, you can be sure you are using the most up-to-date visual and functional paradigms of both platforms. That means iOS8 and Android KitKat today, and future-proofed for the next generations."

Like Lollipop never happened.

zan··on Ask HN: Learning about Type Systems
For me it was just the experience with both. Coming from Java background it was exactly the opposite when I was first dynamic languages, but it got easier eventually (quickly).

I guess you just have to try out different approaches (and mixed ones, Dart and ActionScript come to mind) and gradually understand benefits of each way.

Thanks! Got 2 invites now!

Came to London from Slovenia about a year ago. Quite an exodus these days.

On a completely unrelated note - has anyone noticed the numbers actually form a palindrome?
