I think Russel will get his way ahead of Gasly (probably not in turn 1) eventually. Then eventually the Ferrari cars will also make their way passed Gasly.

Antonelli will make his way through the field, fight the McLarens and Verstappen a little bit and then eventually make his way through passed Gasly.

Given how much McLaren and Verstappen are struggling this weekend, I think Gasly will hang on to P5. I could even imagine Alpine using Colapinto to mess up those guys chasing since he's starting up in P7.

Hey guys, My wife is pregnant and the baby is due in September, her baby shower is this weekend. I thought I'd just share my experience of vibe coding a fun app idea and how smooth the process went for me.

For background, I'm a Frontend Software Engineer with over a decade of experience so I had some favourite technologies to work with during this process. Regarding my tools that I used, I just used what I already have for my various side projects, nothing new.

About two weeks ago, I thought it might be cool to build a simple web app where people can guess when the baby will be born (down to the minute). We're planning a natural birth so this makes the birth day and time quite variable.

I kept the scope super specific:

• Mobile first, make sure that experience is excellent.
• Baby blue theme , everyone already knows we're having a boy.
• Capture user emails, so we can email them a link to the app when the baby is born, also serves as their unique ID if they want to come back and edit their guess. This also means I don't have to setup auth.
• Users submit their name, birth date and time.
• Show where other people have guessed.
• Show a little hero section showing a picture of my pregnant wife, with some blurbs and a "≈X days to go" card.
• Email users a confirmation, with a link back to update their guesses.

I made it my goal to build this as quick as possible and I managed to get it all done in a day last week. It was a normal work day where I did about 1-2 hours in the morning before main job work, 1 hour during lunch time, and then 2-3 hours after main job work. This pattern actually worked quite nicely given 5 hour limits for some of my tech choices.

AI technologies used:

• T3Chat: I just have this $8 a month subscription that both my wife and I share for general day to day AI chats. For me it's usually coding ideas, she uses it to generate pics for home decor usually haha.
• Claude Code: $20/month (annual subscription used though) for Opus (Fable was removed from the subscription plans when I built this)
• Codex: $20/month for GPT 5.6 Sol (use on slow mode).
• Cursor: $20/month (also on annual plan) just for my IDE, I didn't actually use the AI features inside Cursor during this project, but I do really like it for other projects.

I basically used my T3Chat sub to prompt Fable to get a plan out (I knew which technologies I wanted to use upfront from personal preference). Then I started the project. If I remember correctly, I used Codex (GPT 5.6 Sol) to tackle the main work and just asked it to keep my documentation up to date in case I wanted to hand off to other agents. Then I'd just use Claude (Opus 4.8) to do random side tasks outside of the main work to polish what Codex did as I went. The workflow was very much just switching between terminals and looking at the outcome and tweaking from there as the main thread hit milestones that it defined by itself.

Tech Stack:

• NextJS framework hosted with Vercel. I sometimes use TanStack Start for personal projects, but figured it'd been a while since I worked with NextJS).
• Convex for database and serverless functions, the fun thing about this is everything is realtime by default, so at the baby shower, people can see the guesses flowing in without needing to refresh.
• Resend for emails.
• Even though I didn't care about code quality that much for this short lived project, I still setup oxlint and oxfmt haha. Although I didn't bother with setting up CI steps aside from auto deploying Vercel and convex together (this is all done via Vercel though).

SEO wasn't important to me at all, but there were certain quality of life things I did add regarding that including making a solid effort on having good a11y. Things like page titles etc, where useful to make that mobile experience better. I even made a really nice OG image for sharing the link on WhatsApp. The friend organizing my wife's baby shower is going to print a fat QR code that people can scan at the event to make their guesses from there.

I did do some setup to lock the predictions 3 weeks before the baby's actual due date, by then we would have done all the pre birth celebration vibes with friends and family so everyones votes should be in. Then the app will work as is, just without the submission form visible.

There is some boilerplate setup for after the baby is born where we will share details of his birth, like his name, time of birth, weight, picture etc. And then I'll redeploy the site as a nice landing page for people to see how they ranked with their guess on a leaderboard. When I do this I'll also send them a nice email version with their personalized rank on how their guess was, so the email capturing doubles up as a way to announce the birth.

All in all, I've shared it with my close friends and family and even my very non-technical mother-in-law made her guess without requiring any assistance from us which I feel is a great win! We even added a donation button in the footer that pops up our banking details (direct link also opens it) for the family that have been asking how they can contribute.

Why am I sharing this?

I just thought this was a really fun project that might inspire others to go build fun minimal scoped projects. People really can just come up with their own little personal hackathons and have a jam and end up with something fun to share.

If I could do this in day, I'm sure plenty of other people can also come up with things like this to do over a weekend, or casually over a month.

This idea kind of stemmed out of my my public project GrandPrixPicks.com that my friends and family use (but we're keen to get others to join us) to make guesses on Formula 1 results :)

Keep learning, keep having fun, and enjoy!
