Show HN: The CTO Game – Scale your infra in real-time, under pressure

https://thectogame.com/

I made this game because I didn't like how unrealistic System Design can be in interviews. You're incentivized to make your design as elaborate and fancy as possible so you can show how smart your are and there is a slight negative bias towards "simplest solution that meets the needs"Therefore, I made this game to help me practice my real intuition for what decisions makes sense given a...

Re:Ripple, a puzzle game about 2nd and 3rd order effects on Sunday January 04, 2026 @04:56PM (#46492702)
Cool concept! However, the fact that it's on a timer and you can only try the next even in 1m is a killer feature (in a not-good way). Same for not being able to view the leaderboard

Historically this has never flown.

There's only 1 billionaire for every what, 10M people, 100M ? They are outnumbered. At some point the underclass may band together and kick off a revolution to overthrow the ruling class.

Kings have gotten their heads chopped off when the people had enough.

I can see a version of history where the end of capitalism was AI and the AI-owning class with their robots and capital essentially dispose of the majority of the society. Society decides this system is screwed and decides to overthrow capitalism and we invent a new system.

After all, at some point, smart people came up with capitalism to solve the previous system's problems. We may not go to socialism but invent something new entirely to address the flaws of late stage capitalism.

Yea it ends on that date. I cashed out with $622K

I do get answers. The ones who typically said can't disclose are you full of shit. Crack teams know they're cracked and they will tell you.

"I'm a MIT-trained security engineer; I'm an ex-VP at Paypal, etc..."

Damn. Now I understand VC's a little better.

Some deals I saw "damn the traction is off the chart" and I didn't even care to ask any question I just threw money at them. I saw one startup named Salesforce, a CRM. I guess hindsight is 20/20 on that one lol. Didn't even read the pitch.

This game is awesome

Re:Show HN: A game where you invest into startups from history on Thursday November 20, 2025 @03:58PM (#45997627)
Fun game! My investing strategy is to flush out quickly who's the team, what's the traction, what's unique insight into the market.

Bullshitters have trash or no answers. Killer companies have one of those 3 that is usually very compelling.

OP here. I should've added that clarification but it was to say as someone with the "most to gain" financially or professionally from AI becoming more important, I'm still against this content trend and find it is unproductive.
The ideas submitted still go through you where you approve/reject.
Good platform. A similar one was made I used to use back in ~2020 but eventually I think it died.

The best addition would be to have a simple form where people can submit ideas for questions. It'll keep your site from being stale and fading out of relevance like the last one.

Ask HN: Mamdani is poised to become new mayor of New York. How do locals feel?

Title says it all. I've been watching the story from afar. He's dynamic but his agenda to me comes as off as too idealistic and not grounded in the practical reality of how government really operates in terms of inertia and lack of incentive for long-term improvement.But I digress. What I think doesn't matter. I'm curious to hear what locals make of this? Do you generally agree with his...

Re:Meta is axing 600 roles across its AI division on Wednesday October 22, 2025 @03:37PM (#45674105)
You are looking at it wrong. Meta is a business. You know what they sell? Ads.

In fact, they are the #1 or #2 place in the world to sell an ad depending on who you ask. If the future turns out to be LLM-driven, all that ad-money is going to go to OpenAI or worse to Google; leaving Zuck with no revenue.

So why are they after AI? Because they are in the business of selling eyeballs placement and LLM becoming the defacto platform would eat into their margins.

Hey OP here. You're not wrong! Leaving aside the philosophical debate (isn't all form of capitalist participation selfishly motivated?), the main motivator was to help me and my friends with a problem we struggled with.

Many solo Entrepreneurs you see on Twitter with large audiences are busy people so they have hired cheap labor from India / Philippines to be the social media manager. They often take on the task of keeping up with the niches and drafting post ideas. The big issue is that the variance in quality of who you hire is very high, and it's also a mental and energy toll to manage an employee who works on the other side of earth.

So the AI helps to scours "here is what all the tech bros are talking about since 3 days ago" and then drafts 3-5 posts and shows them to me so I can curate. I get to keep my page and audience engaged while protecting my time from actual deep work instead of scrolling the feed all day.

Re: on Tuesday October 21, 2025 @10:13AM (#45656078)
Hey OP here. The use-case is to give an Agent the ability to post on my behalf. It can use these class labels to figure out "what are my common niches" and then come up with keyword search terms to find what's happening in those spaces and then draft up some responses that I can curate, edit and post.

This is the kind of work you typically hire cheap social managers overseas to do through Fiverr. However, the variance in quality is very high and the burden of managing people on the other side of the world can be a lot of solo Entrepreneurs.

Re: on Tuesday October 21, 2025 @10:08AM (#45656011)
OP here. I agree! I should've called out why I did _not_ follow that approach as many others have commented the same.

The main reason why is that I needed the classification to be ongoing. My system pulled over thousands of tweets per day and they all needed to be classified as they came for some downstream tasks.

Thus, I couldn't embed all tweets, then cluster, then ...

Re: on Tuesday October 21, 2025 @08:56AM (#45655167)
OP here. We embed both the label AND the tweet. So if tweet A is "I love burgers" and tweet B is "I love cheeseburgers", we ask in our vector DB if we have seen a tweet before that is very similar to B? If yes, we skip LLM altogether (cache hit) and just take the class label that A has.
Re: on Tuesday October 21, 2025 @06:24AM (#45654253)
OP here. I agree with you. For production use we use VoyageAI which is usually 2x faster than OpenAI at similar quality levels (p90 is < 200ms) but we're looking at spinning up a local embedding in our cloud environment, that would make p95 < 100ms and make cost negligible as well.
Re: on Monday October 20, 2025 @07:42PM (#45650812)
Op here. Yes that's right. We do also insert the current text embedding on misses to expand the boundaries of the cluster.

For instance: I love McDonalds (1). I love burgers. (0.99) I love cheeseburgers with ketchup (?).

This is a bad example but in this case the last text could end up right at the boundary of the similarity to that 1st label if we did not store the 2nd, which could cause a cluster miss we don't want.

We only store the text on cache misses, though you could do both. I had not considered that idea but it make sense. I'm not very concerned about the dataset size because vector storage is generally cheap (~ $2/mo for 1M vectors) and the savings in $$$ not spend generating tokens covers for that expense generously.

Re: on Monday October 20, 2025 @07:32PM (#45650733)
OP here. Yes that works too and get you to the same result. Remove risks for bias but the trade-off is higher marginal cost and latency.

The idea is also that this would be a classification system used in production whereby you classify data as it comes, so the "rolling labels" problem still exists there.

In my experience though, you can dramatically reduce unwanted bias by tuning your cosine similarity filter.
