Show HN: Raise Animals – Find every "Raise a ___" game, codes, and updates
by aishu001 | 2025-10-26 07:38:23+00:00
I built Raise Animals , a simple fan-made website for people who love “Raise a ___” Roblox games — like Raise a Floppa, Raise a Peter, Raise a Bingus, etc.

I noticed that game codes, updates, and tips were scattered across Reddit, Discord, and YouTube comments. So I decided to gather everything into one clean, ad-free site that’s easy to search and navigate.

The site automatically updates new game versions, redeem codes, and guides as they appear.

It’s fully static (built with React + Vercel), no trackers, no monetization — just a useful resource for fans.

Would love any feedback or feature ideas!

Rate matters. 6.2Sv in a single hour is fatal. 6.2Sv in a single year is probably less than average for a human from background radiation. The measurement units for ionizing radiation are very complicated and confusing. That's why people are told to not try to compute this stuff yourself. I have code that computes these units and conversions, its not simple. Here is a brief and simplified explanation of how you calculate this stuff.

There are 4 types of ionizing radiation: alpha, beta, gamma/x-rays and neutron flux. Each one has a different rate it is blocked by different materials (water, air, etc). Each one has a different risk to people. You have to compute counts per unit time emitted from a point source for each of the different types of radiation. Then you have to compute the amount of "arc" the person is in. Then you have counts being absorbed and you next multiply each count by a fixed factor depending on the type of radiation. This final number gives you total Greys per unit time, then you then have to divide by the mass of the person. Then you multiple that number by the total amount of time and that gives you total Greys absorbed. That's the number you use to assess risk to the person. For reference, this guy probably got less than 1 Grey. Someone getting radiation treatment for cancer might get 75 Greys.

So please stop trying to calculate this stuff yourself. I'm pretty sure you are doing it wrong. This guy will be fine.

PS Sieverts are a physical measure, Greys are a measure of biological "harm".

The use of RC is orthogonal to the memory safety guarantees of Rust. The use of RC and safety checking of it is handled at compile time, and only the refcounting aspect is runtime.

RC is a form of declaring shared use and is a parallel to shared_ptr in C++.

And yes there are escape hatches for safety that you can explicitly put yourself in. MTE would catch those at runtime , but you would still have prevented a ton at compile time.

There are also escapes you can find yourself in with memory tagging too.

Also, did you really just create a new account (with an inflammatory name) to crap on Rust while still not being able to address the points in my comment?

Yeah, this is an odd word choice. Even as someone only born in that decade, I've heard at least one case from someone directly about their advocacy from before that year; a history professor I had in college once told an anecdote during a lecture about a time he briefed the elder President Bush, who was apparently considering whether to try to pressure Israel to halt settlements on the West Bank (which the professor told us was an example of how much more attention to detail he perceived in the elder compared to his younger one when he became president). I'm sure there are plenty of people around who can recall things much earlier than this.

I think the bigger story here is that there are many talented people who are drawn to California because of the opportunity but would rather live elsewhere. Some people in tech have the benefit of working from home and can be digital nomads but there are many of us who have to live where we work and often that’s not where we really want to be. If he had the same rights and cost of living as Idahoans do I’m sure he’d he’d live in the Bay Area. I would rather live in Seattle and so would my coworker, I know a very talented engineer who sits across from me who commutes every weekend from Los Angeles to Bellevue because he doesn’t want to live here. My boss is looking for land in Spokane to settle down and another coworker lives in Nevada but commutes to work here and stays in hotels. When I lived in Portland the police and firefighters did nothing about the tents and RVs that caught fire next to where I lived. Having lived in Los Angeles the firefighters here do nothing about tents which become molten plastic fissures in the ground so I think they need to get their priorities straight since they have finite time and resources.

Unless you're at a very small company, CTOs set technical vision, choose high level tooling strategy and outline engineering culture in broad strokes, but the nitty gritty of process will be from an engineering director or other role below the CTO. The CTO will probably provide feedback if needed, but they're not in the weeds and won't be able to see problems unless they're raised.
Show HN: MicroDiagram Prototype
by xlii | 2025-10-26 07:42:10+00:00
Hey y'all,

this is something I've been thinking of for a while - a micro DSL framework for diagrams with one implementation. I'll have a write-up about technology soonish, but in short - this prototype written with Haskell, no database, everything server-side rendered, frontend with Unpoly (pulled from CDN), HTML generated manually. Deployed as Cloudflare container with single request taking approx. 0.8ms time.

Note: because it's using naive load balancing there might be some jank as containers wake up.

No data gathering whatsoever outside of requests and also some debug output from parser.

Ah ok, I misunderstood what the doors did. I'd assumed that there were floors because the shrine messages talked about blessings lasting for the current floor.

I think it would help the agency if you had the ability to walk around to rooms of your choice (n-w-s-e and the like). Maybe have the ability to listen at doors to help guess as to what might be inside the next room...

Also, if you can go back to rooms you've already cleared, you can rest up and heal your wounds or whatever.

You could also make it so that after awhile, rooms you had cleared are no longer clear anymore as wandering monsters have arrived - or maybe there's a small chance that a monster arrived right as soon as you left the room. Probably easiest to just calculate a small chance of repop of cleared rooms after every player move.

When you flee, you are panicking and go in a random direction (or maybe you fail to flee). So fleeing could bring you back to an already cleared room, or run you into another room with an even worse monster...

Perhaps some "elite" monsters can sometimes follow you when you flee? So then you have to keep fleeing until they (maybe) give up the chase...

You could also add an ability for a "knight" class called "retreat", whereby you can choose the direction you flee (with a low but random chance that you panic)...

I didn't see any way to level up your companion, or any special abilities other than attacking along with you. Giving them abilities that they use semi-randomly might help add a new dynamic to the game. Maybe some companions are clumsy, or they are usually powerful allies but sometimes play tricks on you. Or they abandon you if you panic, and you must go find them.

You could add stamina dynamics. For example: a knight has heavy equipment, so he tires a lot and must rest. A rogue, on the other hand, is light on his feet and can go long distances without rest.

So they keep extra file metadata god-knows-where to flag internet downloaded files, to disable their preview because their preview sucks and is insecure? How about they make their preview, I don't know, just render local documents without following URLs?

What a shit OS. I can't believe there are still so many tech oriented people willing to put up with this crap just to keep their habits.

What is the purpose of those animations? If I could use them in a presentation where I click through a diagram adding things as i click and their connections being animated for highlight then sure. I don’t really like the example where the text changes in you link, the whole diagram jumping around just because a text changes seems like something that would be annoying. So I guess you would need to render everything and keep some things hidden until activated?!

As a side not, I would love a proper Swimlane-diagram. I think you have all the building blocks with your ability to nest things in flowcharts, just need to force-align some boxes in different swimlanes and align the lanes themselves (and probably a lot more behind the scenes).

As you say, dams are a net positive, and while failures do happen, these days we tend to be wiser about where we put PHES in particular.

I guess I’m surprised it isn’t more of an option for California - the U.K. uses Snowdonia as a giant battery, and afaik there’s been one failure of a dam that wiped half of trefriw off the map a century ago - which wasn’t hard as it’s a speck of a place. Since then the lakes have pretty reliably and safely provided somewhere to stick excess energy, and now are largely pumped by the offshore wind arrays nearby.

California has big mountains, but I’m not sure if the geology or terrain is right for PHES.

While I think CTOs should take steps back from pushing to production systems because there's a lot of I dotting and T crossing that needs to happen with production systems that CTOs don't reasonably have time for, if a CTO wasn't writing experiments and building test systems to determine technical direction, or at least getting their hands dirty with said systems produced by their top principles, I wouldn't trust their judgment to set direction.

I want to move a project I work in over from tsc to tsdown this week at some point, also with the unbundled mode.

Currently we're using tsc with the new build mode to build everything at once, but the result is incredibly brittle and requires a lot of unnecessary extra configuration all over the place that tends to confuse people when they need to add extra packages or make changes somewhere. It's also very slow (hopefully something that will be fixed by tsgo, eventually).

My initial plan was to have a separate tsdown config in each package and use pnpm to build the entire monorepo (or at least, the parts necessary for each sub-application) in parallel. But your config also looks like a useful approach, I'll explore that as well. Thanks for sharing!

Are you sure you need such a device? If this is to occasionally manage that headless system, wouldn’t a Remote Desktop connection work fine?

You’re mentioning a Mac Mini and a MacBook elsewhere, so https://support.apple.com/en-gb/guide/remote-desktop/apdf49e... might be sufficient for your needs.

I'm not saying AI is living up to the "hype" or "expectations" - it would largely depend on how you quantify the hype or expectations. Most rational would be to consider how much money is funneled into vs how much ROI would it have within some time range in the future, e.g. 10 years. A wise investor would look ahead 10 years, balance benefits, potential and risks. By that metric it could be too early to say if it's paying off even if it's objectively clearly bringing 10x more expense than income.

But the metrics or facts without context or deeper explanations also don't mean much in that article.

> 95% of AI pilots didn’t increase a company’s profit or productivity

If 5% do that could very well be enough to justify it, depending on for which reasons and after how much time the pilots are failing. It's widely touted that only 5% of start ups succeed, yet start ups overall have brought immense technological and productivity gains to the World. You could live in a hut and be happy, and argue none of it is needed, but none the less the gains by some metrics are here, despite 95% failing.

The article throws out numbers to make a point that it wanted to make, but fails to account for any nuance.

If there's a promising new tech, it makes sense that there will be many failed attempts to make use of it, and it makes sense a lot of money will be thrown in. If 5% succeed, it takes 1 million to do 1 attempt, but the potential is 1 billion if it succeeds, it's already 50x return.

In my personal experience, if used correctly it increases my own productivity a lot and I've been using AI daily ever since GPT 3.5 release. I would say I use it during most of what I do.

> AI Pullback Has Officially Started

So I'm personally not seeing this at all, based on how much I personally pay for AI, how much I use it, and how I see it iteratively improving, while it's already so useful for me.

We are building and seeing things that weren't realistic or feasible before now.

Copying the abstract here, just in case anybody don't have access:

Emily Austin, Hilary S. Myron, Richard K. Summerbell, Constance A. Mackenzie, Acute renal injury cause by confirmed Psilocybe cubensis mushroom ingestion,

Medical Mycology Case Reports, Volume 23, 2019, Pages 55-57, ISSN 2211-7539,

https://doi.org/10.1016/j.mmcr.2018.12.007. (https://www.sciencedirect.com/science/article/pii/S221175391...)

Abstract: Psilocybe mushrooms are consumed for their hallucinogenic properties. Fortunately, there are relatively few adverse effects associated with their consumption. This is the first reported case of acute kidney injury (AKI) secondary to confirmed ingestion of Psilocybe cubensis mushroom. A 15-year-old male developed symptomatic AKI 36 h post-ingestion of Psilocybe cubensis mushrooms. He was admitted to hospital with hypertension, nausea and abdominal pain and a creatinine of 450 mmol/L. A sample of the crop of mushrooms was confirmed by mass spectrometry to contain psilocin. On day 5 post-admission, he was discharged home. Outpatient follow-up confirmed complete resolution of his renal function.

Keywords: Psilocybe; Nephrotoxicity; Mushrooms; Kidney injury

Hell yeah. I was honestly pretty surprised by this reaction here. On one hand, I can agree with the argument about focusing on strategy rather than coding — it makes sense. But on the other hand, I’m personally so tired of all this management bullshit out there, where the higher-ups have no idea about even the high-level technical abstractions of what’s going on under the hood in the projects they’re leading. Just imagine the level of incompetence when a Staff Engineer can mislead a Project Owner about the complexity of implementing simple pagination — and the POs and PMs are totally fine with it, like, “let’s just postpone it.” Hell yeah.

You are correct, my post was more for the situation where the CTO is also the engineering director but in larger orgs that is not usually so.

I do think, however, that the coding CTO is not the way to go about to change the process. If it's too cumbersome, the CTO should talk with engineering director to find a way to make it less so, not just bypass the process.

Doubtful. They've already tapped out the white-collar classroom market with iPads, and macOS isn't getting good enough to convert Windows diehards. Frankly I think Cook is making the right decision here, the A-series Macbook is basically guaranteed to be a loss-leader compared to other hardware so you might as well drive current customers to more expensive (eg. redesigned Air) models instead.
by hunterpayne | 2025-10-26 07:55:07+00:00
You need a device that can measure the different types of radiation. Then you have to do a bunch of calculations to estimate absorption. Only then can you calculate Greys which is the measurement that matters.

PS 300 CPM is nothing. There are places where people live where the natural background radiation is higher than that. Also, background radiation is mostly Gamma rays which is more dangerous than what comes off of fission products or nuclear fuel.

I see that you're back to your old self, Stefan, after for a moment it almost looked like you've dropped it and moved on.

Will you ever move on? You do know that what you want is for me to stop being me and that is something I simply cannot do, right? This can't be fulfilling, especially given it's a reaction to once being part of the in-group.

As a fellow adult, I would really wish for you to somehow make peace with this fundamental incompatibility.

It is probably me. I am incompatible with the world how it is now. You're okay the way you are.

What else can I do other than putting up many, many warning signs?

__

Anyway.

Lie is a very strong word you're using there. What is true is that I'm certainly not providing a high-speed instant path to achieve that, but just because there isn't a large neon arrow pointing at a high-speed industrial conveyor belt, doesn't mean that there wouldn't be a set of stairs close by.

Finding those stairs and bothering to walk up is in itself another filter in the spirit of the CoC and the appeal process. Essentially, selecting for caring and bothering instead of "needing to fix this one thing to get back on track".

Sorry, I should've been more specific, I can explain.

> My local utility is well aware of that, applications for permits to net meter have to be made, and only a fraction (something like 15%) of properties in each area can net meter.

Okay, that changes things. The way it worked here is that anyone in the country could install solar and get grandfathered into net metering (perpetually), and then at a certain point they decided to cut it off completely. So you have people from before with who have net metering, and anyone installing it later doesn't have it.

People would install 10-20kW worth of solar, overproduced massive amounts of energy in the summer and then in coldest part of winter (with heat pump COP dropping below 2), people expected to draw 4-10kW of power for heating and pay close to nothing all year round.

The government decided that this was unsustainable so they changed the distribution rates. In effect anyone who doesn't have solar pays roughly the same as they did before, but anyone who has net metering pays substantially more than they thought they would when they signed up.

Ultimately I think this is fair but many people felt cheated by this change. I'm assuming the same could happen elsewhere so I wanted to warn others who might be looking at net-metering deals that look "too good to be true".

We should expect pullbacks, fuckups, plans failing, and rollouts getting canned. It's part of how humans do things. Its actually a pretty effective optimization algorithm.

I'd bet that some sort of exponentiate the learning rate until shit goes haywire then rollback the weights is actually probably a fairly decent algorithm (something like backtracking line search).

It's really not that crazy. You log onto a server, the server communicates your skins to the other clients. Counter strike itself literally did this in the 2000s, it was removed. Modders for other games working for free figured it out. Games used to automatically download maps and skins in a bunch of Valve games as well as other games.

I would also consider building comments into a webpage pretty trivial, it was like the second thing I did when teaching myself web applications years ago.

I bet it's harder in modern frameworks than it used to be, but that doesn't make it a hard problem, we just surrounded an easy problem with more difficult but unrelated problems.

Quickdraw was revolutionary, it had all the optimizations, and then all the code was in assembly. Things like classic arcade games were very much possible. I had a lunar lander game with side scrolling landscape, a dig dug clone, a variation on donkey kong, and a variant of Robotron. Apple thought that would attract the wrong impression, they wanted the design and typography crowd. Can't say they were wrong, to be honest.

Operating Systems are more stable compared to early nineties, but not 2010. I was using NT4 in the late nineties, and it was rock solid. I had a Sun Ultra 1 at home at the time, and that was rock solid too.

Stability got good in the mid-late nineties for most Operating Systems, it's mostly plateaued since then, because it's not like you can be more than 100% reliable. My Sun Ultra 1 never once crashed in the time I owned it, same for my NT4 machine at work.

For people who are unfamiliar, k-means is a partitioning algorithm that aims to group observations into a specific number (k) of clusters in such a way that each observation ends up in the cluster with the “nearest” mean. So say you want 5 groups, it will make five groups so that every observation is in the group where it’s nearest to the mean.

And so that raises the question of what “nearest” means, and here this allows you to replace Euclidian distance with things like Kullback-Leibler divergence (that’s the KL below) which make more sense than Euclidian distance if you’re trying to measure how close two probability distributions are to each other.

I get the feeling that you don't know how complicated calculating radiation exposure is. There are plenty of interest in fear mongering against nuclear. Almost all the people talking about how much radiation 300 CPM is have absolutely no idea what they are talking about. Some confuse total measurement units for rates; others are using just the wrong units; still others are talking about levels that are 1000x or 1000000x higher than 300 CPM.

Or to put it another way, 300 CPM (which is a rate) is less than how much radiation you get when on a flight, or how much radiation you get at higher elevations. Even giving a simple explanation of how to calculate Greys (the actual measure you are looking for) takes up the better part of a page. Hell, your bones are radioactive. Yet there are plenty of people posting that somehow the risk to this guy is radioactivity. In reality, his biggest problem is probably going to be finding a new job.

Consistency and predictability could also be considered a sign of maturity. Maturity is something to be observed, not declared.

It also depends where you draw the line. For example, is dependency injection a matter of taste or a fundamental design decision for a project? What about "defensive" coding practices, like `0 == x` over `x == 0` in C?

I saw the Asimo demonstration at the Miraikan in Tokyo (it's not still on but the rest of the museum is great if you are nearby) and I still look back fondly on it today. I saw it too late (2017 and 2019) for it to feel like the future but there was something lovely about how it had a personality and a charm that some of the other robots there.
