@JackRhysider @signalapp Matrix is to rescue. What’s your take on it?

[Halil Kaşkavalcı @hkaskavalci]

@fatih how do you take such beautiful screenshots?

[Halil Kaşkavalcı @hkaskavalci]

@GergelyOrosz I never use gemini models within cursor because antigravity offers generous rates already. Why would anyone pay cursor to use google models where they can get it for free from the source?

Cursor's data is not the authority on usage. However, I agree that google is behind.

Gotta be careful when prompting AI. It asked me to choose a path, I picked the safer one, but didn’t restate the prompt. 27 mins and 200k tokens later, it accidentally executed a completely different pending task.

Low-priority tech debt fixed at @HelloMinifil! 😅

[Halil Kaşkavalcı @hkaskavalci]

Using multi agent to preserve context and each milestone in plan is committed. 16k lines added and 14k removed. No dead code remains.

Recently, I've moved from subscription model to credit based model. This not only means a massive refactor but also changing e2e tests and manual tests to ensure everything works well. I scrapped all tiers of subscriptions. 🧵

[Halil Kaşkavalcı @hkaskavalci]

Now, only using best frontier models to create images and charge a flat fee. Refactor went well with Codex planning + Cursor auto for implementation and integration tests. Manual tests with stripe cli. I'm impressed how AI did this in one go!

[Halil Kaşkavalcı @hkaskavalci]

In the end, I went with the simplest, static option for now just to get it live.

For the internationalization crowd out there: what's your go-to way to dynamically handle localized OG images without tearing your hair out? #buildinpublic

[Halil Kaşkavalcı @hkaskavalci]

I love solving complex engineering challenges, but now the real test begins: SEO and frontend. Currently optimizing Open Graph cards so @HelloMinifil looks right on every platform. Shoutout to https://t.co/CieWwhPNQl for making the image tuning easy! 👇

[Halil Kaşkavalcı @hkaskavalci]

The second attempt with the logo looked much better.

Next, it suggested using Satori to dynamically generate images. Perfect for a multilingual site like https://t.co/eNlwf3xIL4. Sadly, the rendering results were pretty disappointing. Maybe it just needs more love. 🤷‍♂️

[Halil Kaşkavalcı @hkaskavalci]

Let's jump on the #buildinpublic bandwagon.

I’ve been working on this off and on for a year but kept it quiet. From now on, I’ll post more about @HelloMinifil, my app for parents of toddlers. Built to solve my own problems, now live!

[Halil Kaşkavalcı @hkaskavalci]

@levelsio would be nice to see historical changes to the indicators as currently it simply screams "sell".

[Halil Kaşkavalcı @hkaskavalci]

@levelsio You can’t compare human babies with pets! They basically eat and sleep. Toddlers, maybe.

[Halil Kaşkavalcı @hkaskavalci]

This is the logo of Utrecht water board. I'm not even mad that I need to pay €1100 tax anymore. Take my money.

[Halil Kaşkavalcı @hkaskavalci]

it blows my mind that a paper from 1888 is behind a paywall.

[Halil Kaşkavalcı @hkaskavalci]

@ahbap derneginin 2018 bagimsiz raporu 2024'te gelir mi acaba?

[Halil Kaşkavalcı @hkaskavalci]

@GergelyOrosz CGM / lifestyle products. One from EU: https://t.co/wUAkAgt9cV

[Halil Kaşkavalcı @hkaskavalci]

Pegasus tan damping. Sana özel %50 indirim €0.48😁

Her seferinde bakayım gerçekten indirim var mı diye her seferinde yanılıyorum.

[Halil Kaşkavalcı @hkaskavalci]

@EngGuidebook Looking forward! A link to the Amazon would have been nice :)
