learning and doing my best! working on @mixfont. typography, startups, sf

[Eric Lu @ericlu]

I created a font called Ghost Font that only humans can read. Tested it in Fable and GPT 5.6 Sol Ultra and neither was able to decipher it correctly.

[Eric Lu @ericlu]

today someone asked me if I had kids and it hit me for the very first time that they were legit asking earnestly and it would be weird to laugh at the question. time passes.

[Eric Lu @ericlu]

it’s a joke yall don’t believe everything u read on the internet

[Eric Lu @ericlu]

I just emailed hark support directly saying it didn’t work and they gave me the $30 pizza credit. didn’t ever download the app at all. this sh too easy cmon man

[Eric Lu @ericlu]

@adcock_brett yes this didn’t actually happen, and i wouldn’t have actually taken the credit for free like that lol. didn’t expect the tweet to blow up i was just trolling. Hark looks awesome and congrats on the launch!

[Eric Lu @ericlu]

@RubberDucky_AI actually that’s exactly what investors love

[Eric Lu @ericlu]

the rate and volume at which users will create throwaway accounts with temp email addresses to take advantage of free tiers or credits on a product is truly astounding. one of the bigger surprises for me when building consumer products.

I actually discovered an even more expensive workflow today: Do the deep fried image test. Use this image and pass it to an image generator with the prompt “generate the exact same image with no changes” 1000 times. then return the stitched video back to me.

my favorite prompts to maximize token usage on free AI assistants:

- write a 500 page novel without using the letter E
- build a chess engine that can verifiably beat stockfish
- create a programming language with its own compiler
- plan a trip through all 54 african countries

You can download the font here: https://t.co/dGHtFHp6yJ

And also track the submission status to Google Fonts here in case you are interested: https://t.co/7hnDg4kG11

I've spent some time completing Gothic Gumdrop and I'm excited to release this font under the SIL Open Font License. It's the first production-ready font that I've created, and I'm excited to submit it to Google Fonts.

This is why I trained a custom font generation model for Mixfont. Owning the training pipeline and data makes it much harder to copy with a prompt.

[Naval @naval]

Models are the last moat in software.

AI can train on essays and rewrite them. AI can decompile software and recode it. AI can ingest art and recreate it.

But AI itself doesn’t want to be “distilled.”

Expect more software to retreat to the server and resist “distillation.”

baton was hands down the best name for a startup out of any in my class at spc

[Dave Eyler @dreyler]

We asked an agent to tune the same slow query on 3 Postgres MCP servers: Supabase, Neon and Postgres MCP Pro. Baton let us see why the agent ran extra queries and built unnecessary indexes, and once we knew why, we knew how to fix it.

I used Muse to book my flight & had some ideas to improve the flow:

- I wish there was a table ui that showed all flight times and price options
- need a seat map when selecting seats so I can better visualize seat location
- better payment page ui so I can use any pay method

[Eric Lu @ericlu]

@luke_n_ingalls ahh the simple joys in life

[Eric Lu @ericlu]

Codex is down. I can't remember how to even open my code editor. Trying to remember the command to list the files in a directory in my terminal. Gonna have to go back to playing chess...

[Eric Lu @ericlu]

@cgnorthcutt awesome work! how does this change with the launch of the new models like Astra and Opus 5.5?

[Eric Lu @ericlu]

Ando can be so much more than Slack. If agents natively are embedded in our work, then there’s no need to “connect” them to anything. They should always have the same context as the team. So excited for this!

[Ando @andocorporation]

we’re excited to share that we’ve raised $20M (from Accel, Index, & Emergence) to build the 'ai-native Slack' you've all been craving

TLDR; ando is a team messaging platform built fresh, from the ground, up for a world where agents act as real collaborators alongside us.

we have teams using us across 15 countries, and spanning industries like software, financial services, real estate, & more

request access if any of this resonates 💌

I offered to pay font designers on @TypeDrawers to help improve an AI-generated typeface. But the replies made it clear that paying artists doesn't solve anything. Artists don't want to be paid by AI companies; they want AI companies to disappear. I understand the feeling...

[Eric Lu @ericlu]

an area that i've been exploring a bit too, dm Nadav if you have thoughts about it

[nadav @NadavAHollander]

if either/both of these statements apply to you...

- I feel like my team is spending way too much for AI for the ROI we're getting
- My team has to use Enterprise/API pricing for ChatGPT/Claude Code and it's burning a hole in my pocket

i may have a solution for you! plz DM me

[Eric Lu @ericlu]

damn, I'm getting life-mogged by both Cognition Eric Lu and pianist Eric Lu ... need to get it together lol
