justhw··on SynthID Detector
I tested about 8 pictures. All 8 were made with OpenAI and Google. 2 were altered by and had text and picture overlays. The 6 didn't and SynthID caught them. The 2 altered passed. Interesting!
justhw··on Too AI; Didn't Read
The irony is it's ai generated. It has codex's markings all over it. That lime green look is a dead giveaway.
justhw··on Ask HN: What are you working on? (May 2026)
I've been working on https://thumbnail.ai/ full time for a year now. It lets you make thumbnails for your social media and youtube videos with preset templates. Going great so far. I'm looking for a marketer/content creator to grow it.
justhw··on We ran over 600 image generations to compare AI image models
I came to the same conclusion as the authors after generating 1000s of thumbnails[1]. OpenAI alters faces too much and smoothes out details by default. NanoBanana is the best but lacks high fidelity option. SeeDream is catching up to NanoBanana and sometimes is better. It's been too long since OpenAI's gpt-img-1 came out, hope they launch a better model soon.

[1] = https://thumbnail.ai/

justhw··on Ask HN: What Are You Working On? (Nov 2025)
I've working on an AI Thumbnail Generator for making YouTube thumbnails and social media images the last few months. https://thumbnail.ai/
justhw··on Cursor 1.7
Since finding out a Claude Code extension to run on VS Code/cursor, I use it less and less. With git and Claude Code, rolling back and forth is a breeze. Cursor is cooked, as the cool kids say now days. They need to adapt and find a moat.
justhw··on Ask HN: What are you working on? (September 2025)
I'm working on an AI thumbnail/graphics maker using the various image models.

https://thumbnail.ai/

You just upload a picture and pick a design type and it generates a thumbnail for you. Got good feedback last time I posted, steadily and slowly growing now.

An Ai Thumbnail maker https://thumbnail.ai/

I'm working on an AI thumbnail maker. You just upload a picture and pick a design type and it generates a thumbnail for you. It's still v1 and would appreciate feed back.

By 'programmers' you mean like playlist owners, channel owners etc... right?

justhw··on Show HN: Dropflow, a CSS layout engine for node or <canvas>
This looks great. I've been using html2canvas but it doesn't support the 'filter' property yet. This will be an awesome alternative.

I didn't need/have either but some people that had said it helped.

Definitely do bring a mask and glasses. The volcanic acid is no joke. Everything else would be provided by the company. They usually have camels to carry your stuff as well. Check out a group called Ethio Hiking Community on Telegram. They go roughly once a month.

Oh wow! I visited the Afar region in 2018. It's an incredible place. Pictures don't do it justice. Go if you can. Feels like being on Mars (not that we know). There are plenty of tour and travel groups that still go there. You will also get to sleep next to an active volcano (Ertale) on night 2. Be ready to hike. AMA if you're curious.
justhw··on Show HN: Aldi Price Map
Most vegetable/fruit prices seems cheaper on the west coast. I assume because most are produced and in California and don't have the added transportation costs?

justhw··on Google no longer offers new domain registrations
I wrote this 9 years go > The last thing I trust Google with is my domains. They can outright ban or disable you just like with any of their products and not offer support or explanation.

Google will eventually kill all products that do not help them sell ads. Keep that in mind.

justhw··on 1k True Fans (2008)
What genre if you don't mind? I'm curious if we can hear your mix.
justhw··on Could you be a web designer?
Way too hard. Not a lot of people can tell the difference between a border-radius 3px 5px & 7px with their bare eyes.
justhw··on Banned from Google AdSense – 70k gone, no explanation
They took $10k from us a while back for similar reasons.

We just signed up with a completely different account (with vpn) and fixed the concerns and made 10x more.

You gotta play the game with Google.

justhw··on Ask HN: Is having a personal blog/brand worth it for you?
Good to see you still check out HN :) What happened to the old username?

Very cool. Are you getting the images manually? I built something similar a while back but never took off.

I bring back about 10 kilos of enset powder (kocho) every time I go to Ethiopia. It’s an incredibly healthy food.
