Not shade, and it's a small thing, but why do you list your investors as social proof here?

Isn't the target persona someone who'd be at best indifferent, and at worst distrustful, of a tech product that leads with how many people invested in it? Especially vs the explanation and actual testimonials you're pushing below the fold to show that?

> Terminology-wise, does this read like a better title instead?:

Generates does not convey any info on the nature of the process used to create the output. In this context, extrapolates or predicts or explores sound more suitable.

But nitpicking over these words is pointless and represents going off on a tangent. The use of the term "hallucination" reffers to the specific mechanism used to generate this type of output. Just like prompting a model to transcode a document and thus generating an output that doesn't match any established format.

I would really appreciate it if the Bay area got real congestion pricing and also enforcement. We have lots of HOT lanes here, but they are basically unenforced so everyone sets their ez-pass to “3” and gets the free HOV pricing, which rapidly becomes economical at the rate of enforcement in the Bay.

Frankly, if they let me citizen report - I could likely cover my entire tax burden in 2-3 days. At $490/ticket, the ROI for enforcement seems obviously there.

Author here. I started this project after reading the earlier threads on DeepSeek-OCR [1][2]. I got really excited about "vision for context compression," but after reading their paper, a couple things were bugging me.

They show good OCR results (image → text), but the pitch is context compression (text → image → text). They never actually test that pipeline. So I implemented it: render text, compress to vision tokens, reconstruct. Then I compared against just compressing the text embeddings directly. Mean pooling (averaging embeddings in a sliding window) nearly matched DeepSeek-OCR. A small conv encoder crushed both.

Ok so fine, maybe vision isn't special for reconstruction. But maybe the path matters more than the destination. Do the representations learned through vision work better for language modeling? I finetuned the checkpoints from the reconstruction experiments for next-token prediction. Vision and mean pooling couldn't beat truncation, but the conv encoder could. I didn't do any architecture search. It just worked.

That said, this is preliminary work. I just wanted to answer the obvious next questions. So far, the findings don't support the "vision for context compression" narrative.

Happy to answer questions.

Hardware acceleration has been a thing since...forever. Video in general is a balancing act between storage, bandwidth, and quality. Video playback on computers is a balancing act between storage, bandwidth, power, and cost.

Video is naturally large. You've got all the pixels in a frame, tens of frames every second, and however many bits per pixel. All those frames need to be decoded and displayed in order and within fixed time constraints. If you drop frames or deliver them slowly no one is happy watching the video.

If at any point you stick to video that can be effectively decoded on a general purpose CPU with no acceleration you're never going to keep up with the demands of actual users. It's also going to use a lot more power than an ASIC that is purpose-built to decode the video. If you decide to use the beefiest CPU in order to handle higher quality video under some power envelope your costs are going to increase making the whole venture untenable.

I'm the author of this tool that evaluates effective AWS access locally. AWS launched ABAC support for S3 buckets (https://aws.amazon.com/blogs/aws/introducing-attribute-based...). In this new model you have to turn on ABAC per bucket.

This post shows you can use iam-lens to preview the effects of turning on S3 ABAC locally before actually enabling it on a bucket.

> though diesel engines spit out a bunch of bad stuff.

Exactly. The noxious tailpipe emissions in a city are usually from diesel trucks, small vehicles like motorcycles (small or absent catalytic converters), modified vehicles (catalytic converter removed or diesel reprogrammed to smoke), but not modern gasoline ICE vehicles.

The love for diesel engines in many European countries was always confusing to me.

PM2.5 is also a broad category of particulates that come from many sources. The PM2.5 levels in the air depend on many sources, with wind being a major factor in changing PM2.5 levels. It’s hard to draw conclusions when a number depends on the weather and a lot of other inputs.

It's a war, you know. People die. Sometimes in perfectly legal and justified strikes, sometimes in attacks that contravene the laws of war. And given that Hamas uses the civilians under their control as both a sword and a shield, and that Egypt simply refuses their obligation under IHL to allow refugees to flee, collateral damage is an unfortunate inevitability.

Lumping together all civilians killed by Israel in the course of war is overly reductive: Some were killed in unlawful intentional acts, some were unfortunate collateral damage of lawful acts, and some were intentional victims of Hamas brutality, sacrificed at the altar of making Israel look bad.

Because that’s not true. Cars are expensive compared to transit everywhere, but especially so in NYC. This was studied a lot before congestion pricing was implemented and only something like 2% of poor people were going to pay congestion charges. This did not stop a bunch of rich suburbanites from using them as a prop to demand that the city subsidize their lifestyle at the expense of NYC taxpayers, of course.

Show HN: Grok-CLI-MCP – MCP server wrapping Grok CLI (alternative to direct API)
by changxu | 2025-12-10 16:28:45+00:00
I built an MCP (Model Context Protocol) server that wraps the Grok CLI instead of calling the API directly. It provides three tools for Claude Code and other MCP clients: simple queries, multi-turn chat, and code generation. This allows me to use Grok models in Claude Code.

Why wrap the CLI instead of using the API?

The CLI wrapper approach has some interesting benefits:

• Future-proof: When xAI adds OAuth to the CLI, this gets it automatically without code changes • Pricing flexibility: If xAI introduces fixed monthly pricing for CLI usage (like OpenAI's $20/month for Codex), you benefit immediately rather than paying per token • Simpler maintenance: ~400 lines vs 1500+ for a full API client. No tracking API versioning or breaking changes. • Org-friendly: Some teams prefer audited CLI tools over API libraries for security/compliance

Honest tradeoffs:

• Performance overhead: ~50-200ms extra latency from process spawning • CLI dependency: Requires Grok CLI installed • Limited control: Can't access features not exposed by CLI

The sweet spot is development tools, prototyping, and internal automation where convenience matters more than milliseconds. For high-throughput production (>1000 req/min), direct API makes more sense.

Built with FastMCP, fully open source (MIT), and published to PyPI.

GitHub: https://github.com/BasisSetVentures/grok-cli-mcp

Curious to hear if others have taken similar "wrapper over direct integration" approaches for other AI CLIs.

Why wouldn't it happen? America's new direction is that Europe is the enemy, and massive resources will be poured into propelling the already popular right wing parties, which are Russian puppets, into power. They don't need boots on the ground to conquer the continent, they just need a cynical population that doesn't see the difference between good and bad, just like in the US.
by mindslight | 2025-12-10 16:28:54+00:00
Have you seen anything that the current regime is doing? Making the country repulsive for longstanding allies and individual visitors, paramilitary gangs assaulting American cities rifling through homes, hefty import taxes to kill what's left of our distributed industry, demanding fealty from longstanding independent institutions. And the list goes on.

The left's criticism generally comes out of a place of wanting to improve our country, however misguided some of their ideas end up being. Meanwhile Trumpism is basically one never ending litany of grievances against the modern United States, in favor of some imagined rosy past based around religious fundamentalism and corporate authoritarianism.

Since this is generating revenue for NYC, you can't consider whether this tax is good or bad in a vacuum though. The alternatives are a different tax with its own effects, or more debt, or less spending. (In this case, the revenue goes to the MTA.) Any opportunity costs due to less traffic are at least partially offset by opportunity costs you aren't having to pay somewhere else.

TLDR regenerative braking reduces this significantly, nut getting the raw numbers is always fraught with today's horrific AI-addled search engines.

Also seems like a wonderful opportunity for the materials science people to print money coming up with better brake materials here. And if anyone here who can say "clean coal" with a straight face disagrees, point and laugh at them.

Great questions. We’re working on a more formal public benchmark and will share results as our dataset grows. Today, we typically catch coordination issues like conflicting dimensions, missing callouts, building code and clearance violations that humans often miss in large sheet sets. Behind the scenes it’s a multimodal workflow: OCR + geometry parsing + cross-sheet callout graph + constraint checks vs. code/spec requirements.

> Getting medical info from LLMs is great and can save your life.

No its not - LLMs are not medical experts. Nor are they experts for pretty much anything. They just extrapolate statistically the next token. If you fed them anti-vaxer information, theyd start recommending you to not get vaccinated so as to not obtain autism or something like that. We should not use them as experts on anything, much less so for medical information.

On the other hand, if you want to use them to generate large amounts of text and images, sure go do that. They can do that I guess.

They could still get HDR working right end-to-end. I was reading about HDR in the early 2000s and really excited about it but when I looked into the specific tone mapping systems that are used today my impression is: "Great, they're going to screw up both the SDR and the extra HDR data" and it seems that's exactly what happened. Similarly, the net effect of wide gamut on color accuracy in the wild is not necessarily an improvement.

I suspect that this is due to the elimination of toll shopping/avoidance. Per [0] and [1], the only way to avoid a toll entirely is to drive from the West Side Highway or FDR Drive to the Brooklyn Bridge, but commercial vehicles are prohibited on FDR Drive and the Brooklyn Bridge has weight restrictions [2], so heavy trucks don't have a legal way to dodge the tolls anymore.

If you need to reach Long Island, the incentive to avoid the (tolled) Throgs Neck, Whitestone, Verrazzano, and RFK bridges are gone; now you're paying for the privilege of sitting in Manhattan traffic.

Practical argument for vibe coding in C: the training corpus is probably much higher quality.

C code that survives in the wild tends to be written by experienced devs who care about correctness. The JS corpus includes mountains of tutorial code, Stack Overflow copypasta, and npm packages with 3 downloads. In my experience, generated C is noticeably better—and this might be why.

Yeah, those were different times.

On one of my first flights alone, 16-year-old me had forgotten I had a knife in my backpack. X-ray guy took it with him to a back room, measured the blade to be shorter than, idk, 12 cm or so, and just handed it back.

Another time I found a long wood screw on the floor at school, and out of boredom during class, I just drove it sideways into my boot's heel. Months later it gave the metal detector guys at the airport a bit of a pause. They asked me to remove the boots, x-rayed them, came together to admire my long-forgotten idle work, scratched their heads and had me proceed.

Cool, but a little more thought on the content rather than the presentation would improve it. For example starting with an arbitrary segment of DNA double helix and saying how "tall" this arbitrary segment is, is just silly.

Instead, it should show how _wide_ it is. And for extra coolness, keep it in frame, coiling longer and longer as you go, and eventually have the same strand, which has been with us all the time, as a specific example (e.g. human chromosome 7 or some such) by _length_

I think that's exactly the kind of things that make people hate AI.

Author's example for internal help channel has a rule: "NPM related: recommend reading the Fullstack onboarding guide...". So no comprehension, no contextual response. But hey, it's using AI bot for something that could have been a simple FAQ document!

At the same time, the author is clearly proud of the effort and does not seem to be discouraged by the negative experience... I was wondering about this disconnect, until I went to their page and found out they are the CTO. I guess the old quote was right: "It is difficult to get a man to understand something, when his salary depends on his not understanding it."

I've tried generating some dingbat puzzles with Gemini, they are comically bad most of the time with no subtlety. Even for existing dingbat phrases it didn't make good ones, which I would have expected it to have been able to just copy prior examples.

Same with cryptic crosswords, not very good. Sure there's some strategy that would work like providing some tactics to use.

Show HN: Git-scope – Blazing TUI to manage 50 Git repos without CD-ing dirs
by iam_pbk | 2025-12-10 16:33:18+00:00
Hi HN! As a solo dev juggling 20+ microservices locally, I was tired of context-switching hell: `cd` into folders, `git status`, repeat endlessly. No bloated Electron app—built *git-scope*, a Go + Bubble Tea TUI that recursively discovers repos, fuzzy-searches by name/status, and jumps to editors in 10ms.

Key wins: • Filters dirty/unpushed repos instantly (`/` fuzzy find) • Vim keys (`j/k/h/l`), `Enter` opens in VSCode/iTerm • Caches state for sub-10ms launches • brew tap Bharath-code/tap brew install git-scope or go install github.com/Bharath-code/git-scope/cmd/git-scope@latest

It seems to be like some of the scales slightly off?

If you are looking at the ladybird (ladybug) with the amoeba to the left, the amoeba isn't an order of the magnitude smaller - it would actually be visible by the human eye (bigger than a grain of sand)? Indeed, the amoeba seems the same size as the ladybird's foot?

Similarly, this makes the bumblebee appear smaller than a human finger (the in the adjacent picture), which isn't the case?

"relatively clean" means 85% of PM2.5 is from non-exhaust sources, and 15% is from exhaust after catalytic conversion. In New York EV and ICE are pretty much on par when it comes to this category of pollution, as the additional weight increases non exhaust sources. Source: https://www.sciencedirect.com/science/article/abs/pii/S13522...

It is different in Africa, where catalytic converters are harvested for precious metals and cars are driven without them.

For whatever it's worth, Mike Godwin, of Godwin's Law, has called the comparison of Trump to Hitler "apt". https://www.politico.com/news/magazine/2023/12/19/godwins-la...

Editing to add:

> On the other hand, a liberal did kill Charlie Kirk in cold blood because the killer had a trans girlfriend and was mad about Kirk‘a opinions. So, maybe some people should be afraid of violence.

My friend, this is a clownshoes-ass take. First, the motives of this dude are still unknown. His entire family are Trump-supporters. Dude grew up shooting guns and being a good ol' boy (hence the reason he, y'know, had access to, and knowledge of how to shoot and kill someone from such a distance at the age of 22). Second, literally on the same day Kirk was killed, there was a school shooting by a literal Neo-Nazi. And a couple months prior to Kirk's killing, a Trump-voting, anti-abortion nutcase literally assassinated the leader of the Minnesota State House and her husband, shot and nearly killed a member of the State Senate and his wife, and had a list of 70 other, all democratic politicians, he'd apparently intended to assassinate. And here you are still focused on the one time you could shoehorn some cherry-pickin' ass example of an alleged "leftist" being violent into this conversation. For 30 years, right-wing extremist political violence has been far more common and far more deadly than their left-wing extremist counterparts. https://ccjls.scholasticahq.com/article/26973-far-left-versu...

The irony here is, you're simultaneously claiming it's ridiculous to suggest Trump wants to "round-up" liberals, while using the same bullshit guilt-by-extremely-stretched-association rhetoric about Kirk's assassination to paint "liberals" as violent that he's currently using to justify treating his critics as "terrorists". Read through this bad-boy, and with a straight face tell anyone Trump's not interested in "rounding up" his dissidents https://www.whitehouse.gov/presidential-actions/2025/09/coun... Would he be successful in trying this? Probably not. But I sure as hell don't feel one bit certain that people like you would move a muscle to stop it, being so easily convinced of such contemptible nonsense.

It's a tough area, honestly, and will be until public charging is better. You need a bigger battery to get the range that people need (want?) to be able to reach the next charging station. Realistically, though, most people don't really venture far from home but they don't like the idea that they can't venture far from home without finding a place to charge.

EV charging availability has drastically improved over the last few years, so maybe there is hope for smaller EVs.
