Show HN: Scrimm AI - System design interview practice with AI

https://scrimm.ai

While interviewing for different companies and find Leetcode-like platforms to practice system design, there really isn't any good tools to practice that grill me like an interviewer. I built Scrimm.ai to solve a personal pain point: practicing System Design interviews alone is impossible and expensive (if you want to find a real person). You can read books, but you can’t simulate the pressure...

Re:AI for Erotica on Wednesday October 15, 2025 @02:11AM (#45588627)
As Sam Altman just announced ChatGPT can now write erotica, we are ready to announce our AI-powered erotica platform.

Most of us here use tools like ChatGPT for everything from coding to drafting emails. But this creates a problem of "context collapse." Your work queries, personal questions, and more sensitive creative explorations all end up in the same, permanent history. OpenAI (and Grok!) are able to learn about your work and your sexual desires based on your usage on their platforms.

We believe you need a separate, dedicated space for this kind of creativity—a private journal, not a public square.

That’s why we built Sylvaine AI.

Sylvaine is an AI-powered platform designed for writing fiction, with privacy as its foundation, not an afterthought.

The goal is to give creators a sanctuary where they can explore their imagination without looking over their shoulder.

I’m here all day to answer any questions you have about our tech stack, our privacy policy, or the challenges of building a privacy-first AI product.

for companies who hired him and let him go, you should be reviewing your interview system. it looks like we are going back to old argument "coders who are good at interviews (most likely leetcode), but terrible at delivering actual work."
meanwhile, I'm saving the company 7-digit/year from Google.

In other words, companies can replace consultants with GPT-4.

For me, my ears response faster than my eyes in some cases. I think someone else pointed out that when there's a bicycle ringing their bells on your side, your ears will catch it first then you use your vision to confirm it.

Show HN: DashMap – A dash cam navigation app

https://apps.apple.com/us/app/dashmap/id1638360259

Hi HN,The other day I was stuck in traffic, and I looked around and couldn't help myself notice the following. The cars next to me all have the same things -- dash cam and phone for navigation. I thought, why not just one of them?Introducing DashMap, a dash cam app with turn-by-turn navigation. No more pulling out micro SD card or connecting to the dash cam's wifi when there's an accident....

It is unfortunately because of API cost from Mapbox. In Google's use case, they can obviously do it for free (for being Google and not integrated with navigation within the app). The 1 week tier is aimed for rental car users, for normal users, I'd recommend 1 month.

the biggest cost for me is the navigation, mapbox charges quite a lot...on a per trip basis, but you guys can use the promo code HACKERNEWS for 1 month free trial
Hey guys, I noticed that there's a post on HN regarding Pixel's upcoming dashcam function. I find it odd that while we can post things about big tech's new products, we can't post our own work.

So here is mine, I too made my own dashcam app called DashMap. But unlike Google's implementation, DashMap integrates dashcam with turn-by-turn navigation so that you don't have to switch between apps, it automatically starts recording as soon as you start navigation, or if you're just on a short trip, you can just choose to record without navigation.

You can use the promo code HACKERNEWS within the app to use the app for free for a month.

The app may look barebone, but we have a lot of excited new features coming up. Stay tuned :)

not sure if you're using iOS, but I already made one for iPhone.

No need to wait for another two years, I already made an exact app you're talking about. it's not only a dash cam, but also comes with turn by turn navigation as well.

maybe I can claim it to be revolutionary :)
