Show HN: Linux CLI game, quiz, cheatsheet and map from my mind mapping app
by max002 | 2025-10-28 16:26:56+00:00
Im working on a mind mapping app that would allow for integration of gamification features and be nicer and easier to remember. I was missing more advanced graphics from apps and being able to treat it as my note taking and learning tool.

i.e. how (and why?) should I remember a mind map if it looks the same like all other maps and all i can do is pick couple of shapes and dashed/dotted lines?

this simply doesnt work with my brain so i decided to create something better :) map on page is a preview of this, but im curious about the quiz, typing games and cheatsheet, would love some feedback (and ideas) on such training modes!

Another thing i'd love is some comments about any features that you miss in existing mm's soft. If you're mind mapping enthusiast and interested in beta testing checkout contact form :)

p.s. last week i posted simple map, but i didnt realize i can use SHOWN HN for stuff that ive made and that lets you play with something. It just vanished down the pages so ive added new commands, modified all bad answers to be more realistic, and added some features for quiz and typing game and reposting to get proper feedback and hopefully some testers!

as well, if you're not ready to take lengthy quiz [nearly 180 questions] pick a smaller random generated subset to play with it!

Same exact experience here and also with the left AirPod. Everything goes well until the AirPods get just a little bit wet or greasy (say, in the rain, after a run, or a few hours into wearing them) — then the seal loosens and I get a painful high-pitched hum when trying to put it back in it is place. I wonder how safe that sound is bc its pretty uncomfortable.

The seal also changes with any significant jaw movement (which I also do a lot in-flight normally) — noticeable degradation of noise cancellation, which then goes away (not sure if its the foam or anc adjusting).

Tried to use my AirPods Pro 2 earhooks, which partially solved it - although at the cost of that crispy sound. Found best to just wipe the AirPods dry/gently blow around the grills before adjusting (which makes them unusable for running unless you’re willing to stop all the time).

Such a shame every APP iteration has some noticeable flaw. And especially when they solved a similar problem between the first and the second gen.

While I find your comment enjoyably pithy, in the case of vitamin D, many humans are currently living at latitudes which they are not suited to (skin being too dark to generate enough vitamin D given the insolation), and eating diets which do not provide them with sufficient amounts of it (the carnivore diets of Inuits and similar groups being a good contrast).

"These are not government. "

Every country is more than its government. The original assertion was that America doesn't pretend to care about the poor.

Apparently, the assertion should have been "America doesn't care about the poor as much as I feel they should and no evidence you bring contrariwise will change my mind".

It reminds me of the houses in the gated communities with "no borders" signs in the manicured lawns.

Not all pigs and chickens are "factory farmed" but most are. And unlike cows, the term is relatively meaningful and descriptive when applied to the way those are raised. Bro heard about how pigs and chickens get raised in tiny cages never seeing the light of day then assumed that's how it works for cows too, which he now realizes isn't the case because I shamed him into looking it up.

Yawning alters the conformation of the external auditory canal by displacing the mandible, which articulates with the tympanic plate of the temporal bone adjacent to the canal.

The seal might be so good that a small pressure differential happens as cabin pressure drops, which causes some issue with the microphone or speaker. Yawning might break that seal, or otherwise cause pressure equalization. Why only the left one? Apple might put some kind of special signal diagnostics or sensors in that side that bugs out under those conditions, or maybe human anatomy on the left side is consistently subtley different in a set of people.

Because this doesn't happen to everybody it could be some kind of "instrument effect" where the particular shape of someone's ear canal, and the interaction with their ear drum and the speakers and sensors in the app creates this tone, likely assisted by the constant driving signal of air cabin white noise.

This resonates. I do the same - use free tools, only pay when forced.

You nailed it: 'If people aren't upgrading, the free version might be enough.' That's exactly my problem. Level 177 user completes 800+ habits/month on free tier.

So I either:

1. Lock core features - risk losing the 9 power users 2. Keep it generous - accept it won't monetize 3. Shut down

Question: on your website, did you experiment with limiting free usage? Or accept it's a free tool with optional donations?

Tbf, he's kinda on point.

The EU Parlament has it's issues, and it's atrocious how corrupt politicians like e.g. von der Laien fail upwards into leadership roles there, but they're both massively exaggerating the issues to a degree that it's hard to call the stated opinions anything but unhinged.

Its kinda like calling a Chihuahua "apex predator". completely out of touch with reality.

That’s a fair point - the old-school shorteners were just utilities. What’s interesting is how link shortening evolved into something closer to analytics and brand management. Today, a short link isn’t only about saving characters - it’s about tracking engagement, A/B testing, QR integrations, branded domains, and data insights. Tools like Cuttly are trying to push it further - more like a small marketing hub than a URL compressor.
Show HN: ICESight – Computer Vision Tool for Detecting and Mapping ICE Activity
by visekr | 2025-10-28 16:28:41+00:00
Hi HN, I built this after seeing ICEBlock get removed from the App Store.

ICESight is a photo-based tool that uses AI to handle moderation and verification, with human users acting as verifiers. When someone uploads a photo of an ICE sighting, it runs through an object detection model to find possible agents or vehicles. Each detected area is then sent to another AI service that checks if the scene looks authentic.

If it passes those checks, the system saves visual embeddings for each agent in a database and compares them against future uploads. Verified photos are added to a public map where other users can review and confirm sightings.

I hope this can become a useful public dataset that helps improve transparency and public safety. Feedback very welcome!

I've often called people on the phone and stuff. It depends somewhat on what's at stake. Authenticating users with SSH passwords puts much more at stake than using public keys, since an attacker who can get you to send your unencrypted password to a malicious server once can steal your account; deploying PAKE algorithms (successors to SRP, see https://eprint.iacr.org/2021/1492.pdf) could mitigate that, but I don't think any shipped SSH version has ever supported a PAKE algorithm.

Double billing is an insanely common problem. How it’s gone for me in the past is like this:

Provider wants to do procedure. You need it right away, or the procedure allows pre approval with the assumption insurance won’t haggle or deny payment

insurance company denies payment

provider bills you

what i learned is, often, the provider will eventually be paid. do they tell you? not usually. oh woops. I haven’t very successfully fought these other than just hours of phone calls with both companies chasing down what actually got paid and when, and they on purpose make it difficult. If you find yourself in this situation do NOT pay the hospital until the last possible moment it will go to collections. often, you’ll find it mysteriously disappears. it also doesnt hurt your credit very much anyway if it does.

There’s no real defense of these practices or of the industry in general as it exists in the USA.

anything <$500 now by CA law cant show up on credit report so I basically stopped paying those. unethical? sure. will it affect the quality of my care? probably. sometimes though being a deliberate pain in the ass feels better than letting the system fuck you over and over.

My counter argument is that the entire web exists because of Postel's law. HTML would just be another obsolete boring document format from the 1980s.

I agree that there are better ways to design flexibility into protocols but that requires effort, forethought, and most of all imagination. You might not imagine that your little scientific document format would eventually become the world's largest application platform and plan accordingly.

I had a fit issue with Airpods Pro 2 in my left ear. It would always pop out after 20 minutes of rowing. I tried different ear tips, but none of them really worked. ANC is only medium-important to me, so I'm using Airpods 4 with ANC.

Concurring with sibling, AZLA does make good aftermarket tips. I have my Airpods Pro 2 in my work bag and still use their "crystal" tips.
by jerlam | 2025-10-28 16:29:59+00:00
I'm surprised of the general positivity of the previous version, also $250. When the Airpods Pro 2 had been out, it seemed like there was non-stop complaining about how every firmware update made the ANC worse, the sound quality was worse than Sony, continual clicks and rattles, and how they were designed for battery failure.

Just goes to show how negative opinions travel fast.

I experimented with taking 10,000 IU a day for about a year. I had my D levels checked with my normal yearly blood test (lipids, etc) and it put me into the high normal range. I still take 5000 IU daily and have for years with no ill effects.

I should note that I live in a place that sees little sun for five or so months a year.

For reference, the details about how the LLMs are queried:

"How the players work

All players use the same system prompt Each time it's their turn, or after a hand ends (to write a note), we query the LLM At each decision point, the LLM sees: General hand info — player positions, stacks, hero's cards Player stats across the tournament (VPIP, PFR, 3bet, etc.) Notes hero has written about other players in past hands From the LLM, we expect: Reasoning about the decision The action to take (executed in the poker engine) A reasoning summary for the live viewer interface Models have a maximum token limit for reasoning If there's a problem with the response (timeout, invalid output), the fallback action is fold"

The fact the models are given stats about the other models is rather disappointing to me, makes it less interesting. Would be curious how this would go if the models had to only use notes/context would be more interesting. Maybe it's a way to save on costs, this could get expensive...

Wikipedia was the greatest long ago. Then anonymous partisans setup a 'source blacklist' which essentially curates all of wiki for a specific ideology. They acknowledge their systemic bias and have done nothing to fix it. Wiki deserves to give us an apology.

In reality no apology needed from wiki, we just move on to what's better. Grokipedia v0.1 is out and from what I've seen it's shockingly better. Tons of improvements are still to come no doubt. Ive found inaccuracies in articles that I look forward to having grok remedy.

Soon we will get APIs which will slot into searxng well. The plan is to have grok be the only editor. You have to convince grok to edit a page.

Grokipedia's AI editor point of view will thus eliminate the human/ideological abuse of wikipedia.

> I've spotted surprising amounts of confidently-stated nonsense

I find this to be the most annoying aspect of AI. The initial Google AI results were especially bad. It is getting better, but still spout info I know is false without any warning.

Like, I find blowhards tiring enough in RL. Don't really want to deal with artificial blowhards when I'm trying to solve a problem.

> the most powerful new form of knowledge representation since the written word

1. the LLM model is a representation of language, not knowledge. The two may be highly correlated, but they are probably not coterminant and they are certainly not equivalent.

2. the final "product" is still the written word

3. whether LLM's are or are not the most powerful new form of knowledge representation or not, their output is so consistently inconsistent in its accuracy that it makes that power difficult to utilize, at best.

By "standard PKI which is deployed everywhere" do you mean SSL certificates? That would make you vulnerable to dozens of poorly secured CAs throughout the world; any attacker who could penetrate one of them could then use that access to MITM any SSH connection in the world (if they could additionally spoof DNS).

SSL certificates are probably the best we can do for the "talk to a server you've never heard of" scenario, but we can do enormously better for the scenario where you're SSHing into a server you already have a pre-existing trust relationship with.

What you describe is not a contrast to chess. Current LLMs also do not play chess well. Generally they play at the 1000-1300 ELO level.

Playing specific games well requires specialized game-specific skills. A general purpose LLM generally lacks those. Future LLMs may be slightly better. But for the foreseeable future, the real increase of playing strength is having an LLM that knows when to call out to external tools, such as a specialized game engine. Which means that you're basically playing that game engine.

But if you allow an LLM to do that, there already are poker bots that can play at a professional level.

Depends on how you define AGI - if you define it as an AI that can learn to perform generalist tasks - then yes, transformers like GPT 5 (or 3) are AGI as the same model can be trained to do every task and it will perform reasonably well.

But I guess what most people would consider AGI would be something capable of on-line learning and self improvement.

I don't get the 2035 prediction though (or any other prediction like this) - it implies that we'll have some magical breakthrough in the next couple years be it in hardware and/or software - this might happen tomorrow, or not any time soon.

If AGI can be achieved using scaling current techniques and hardware, then the 2035 date makes sense - moores law dictates that we'll have about 64x the compute in hardware (let's add another 4x due to algorithmic improvements) - that means that 250x the compute will give us AGI - I think with ARC-AGI 2 this was the kind of compute budget they spent to get their models to perform on a human-ish level.

Also perf/W and perf/$ scaling has been slowing in the past decade, I think we got like 6x-8x perf/W compared to a decade ago, which is a far cry than what I wrote here.

Imo it might turn out that we discover 'AGI' in the sense that we find an algorithm that can turn FLOPS to IQ that scales indefinitely, but is very likely so expensive to run, that biological intelligences will have a huge competitive edge for a very long time, in fact it might be that biology is astronomically more efficient in turning Watts to IQ than transistors will ever be.

>Then I checked Russo-Georgian War articles, this time at least the century and war was correct in Elonopedia. But again, right from the start it is incredibly biased towards Russia. Elonopedia completely omits the initial attack make bu Russian forces at 01 Aug 2008, skip a week and presents war as if it was initiated by Georgians, following Kremlin propaganda line.

The EU isn't exactly known for being Kremlin propagandists. Here is the link to the 700-page international fact-finding report they published in 2009: https://www.echr.coe.int/documents/d/echr/hudoc_38263_08_Ann...

This Radio Free Europe article is a decent summary of the report: https://www.rferl.org/a/EU_Report_On_2008_War_Tilts_Against_...

Why do you think the international team of Europeans would leave out something like an August 1st attack by Russian forces? Why would the US-funded media outlet for Europe (RFE/RFL) parrot the report's position that the conflict was overwhelmingly Georgia's fault?

"The Mission is not in a position to consider as sufficiently substantiated the Georgian claim concerning a large-scale Russian military incursion into South Ossetia before 8 August 2008."

Can you share the evidence you have that supports your position that Russia attacked on 01 August? The EU concluded that was unsubstantiated.

While grant process in EU isn't fun, I think Levels has bit of an ego issues. He mentioned that if he had issues like that on eg X, he would see Elon himself in the replies.

While he is great at converting his influencer status to income in his micro-SaaS projects, I don't think running ad-fueled browser games on state-sponsored super computer should be really aim of these grant programs.

Other than direct calls for violence (which in a book, really doesn't work that way, since any call to violence would be indirect in a sense), yes, you can publish anything. Any viewpoint at least. You cannot publish certain pornographic pictures (children, bestiality), but you are allowed to publish a book embracing both. Similarly, you are allowed to advocate for the violent overthrow of the American government. It is certainly legal, and many books have been published doing exactly this. I can't imagine anyone wanting to stop it; that's dumb.

I mean, here's a book that not only advocated for the violent overthrow of the US government but gave explicit instructions on how to do it: https://en.wikipedia.org/wiki/The_Anarchist_Cookbook

It is legal (and easily available in the United States), but not legal in many countries, which is dumb. While the FBI investigated the author and the book itself, they concluded that it falls well under the 1st amendment rights of Americans. Again, and I'm not sure how many times I need to point this out, America is really the only free country in the world.

Hi HN!

I've been working on Context Sync (https://github.com/Intina47/context-sync) - an MCP server that gives AI coding assistants persistent memory across platforms and sessions.

Today I'm excited to share v0.6.0, which adds VS Code/GitHub Copilot support and major performance optimizations.

## The Problem We've all been there: you're deep into a coding session with Claude, hit the context limit, start a new chat, and suddenly Claude has forgotten your entire project architecture. You spend 30 minutes re-explaining the same context. Every. Single. Day.

## The Solution Context Sync gives AI assistants persistent memory. Start a project Monday in Cursor, continue Tuesday in Claude Desktop, debug Wednesday in VS Code - the AI remembers everything.

## What's New in v0.6.0 • *VS Code + GitHub Copilot support* - Now works across all major AI coding platforms • *2-5x faster database operations* - Prepared statement caching • *File size safety limits* - Prevents OOM crashes with 5MB max file size • *Real-time cache invalidation* - File watchers automatically update caches • *Async file operations* - Non-blocking I/O for better performance

## Technical Details Built as an MCP (Model Context Protocol) server in TypeScript with SQLite. Local-first, no cloud sync required. Uses intelligent caching, file watching with chokidar, and async/await throughout.

The performance optimizations were crucial - we were seeing memory issues with large codebases, so v0.6.0 adds file size limits, async operations, and much smarter caching.

## Try It ```bash

npm install -g @context-sync/server

For all my constant freak-outs about AI in general, it turned out to be a godsend last year when my wife’s mom was hospitalized (and later passed away a few weeks afterward). Multimodal ChatGPT had just become available on mobile, so being able to feed it photos of her vital sign monitors to figure out what was going on, have it translate what the doctors were telling us in real time, and explain things clearly made an incredible difference. I even used it to interpret legal documents and compare them with what the attorneys were telling us — again, super helpful.

And when the bills started coming in, it helped there too. Hard to say if we actually saved anything — but it certainly didn’t hurt.

They don’t have room for another building the size of the data center to store batteries in and thousands of acres of land for solar panels (wild ass guesses on battery building footprint and solar field footprint)

Critical loads require generators, batteries don’t cut it. Data centers want the most reliable backup power they can with the longest runtime. Battery storage density is not high enough to back up a 500MW+ data center for any length of time without a comical amount of batteries.

When the NEC allows critical, equipment, and life safety branch at hospitals to be backed up with batteries and solar panels, battery storage will be at a point where battery backup of data centers is feasible. Right now it isn’t.

They report benchmarks on the huggingface page (https://huggingface.co/utter-project/EuroLLM-9B)

They almost exclusively compare their model to prior models from 2024 or older and brag about "results comparable to Gemma-2-9B". I'm not sure what I expected. The eurollm.io homepage states "EuroLLM outperforms similar-sized models", which just seems like a lie for all practical purposes

An overly charitable interpretation is that EuroLLM isn't a reasoning model and has minimal post-training, so they sought out comparisons to such models (they're still ignoring reasoning models that have non-reasoning modes)

> which is really similar to what LLM's are doing now, though minus the occasional hallucination.

"Really similar" kinda betrays the fact that it is not similar at all in how it works just in how it appears.

It would be like saying a cloud that kinda looks like a dog is really similar to the labrador you grew up with.

this and many other grants were singled out because of words used in their description. you seem quite certain that 'diversity' here isn't referring to the degree to which the genome of these animals is similar to different to other of their species, but instead a leftist dogwhistle hiding racist intent, and this researcher lost their position because they are really a secret racist and deserves to be 'blowtorched'.

you celebrate the ruin of the career of a highly trained person, frankly a national resource, because they used a word to describe their work that you think has evil connotations.

we are so screwed
