I always found Anthropic to be trying hard to signal as one of the "good guys".

I wonder how they can get away without showing Ads when ChatGPT has to be doing it. Will the enterprise business be that profitable that Ads are not required?

Maybe OpenAI is going for something different - democratising access to vast majority of the people. Remember that ChatGPT is what people know about and what people use the free version of.
Who's to say that making Ads by doing this but also prodiding more access is the wrong choice?

Also, Claude holds nothing against ChatGPT in search. From my previous experiences, ChatGPT is just way better at deep searches through the internet than Claude.

LCF-style provers like Isabelle/HOL and HOLlight are some of the most widely used, and oldest interactive theorem provers. If they consistently show smaller error rates than other systems, that is an interesting empirical observation. To give but one recent example: Amazon recently announced a vast 260000 lines of Isabelle/HOL-checked correctness proof of their new Nitro hypervisor for AWS EC2 Graviton5 instances.

LCF-style provers have a much smaller trusted computing base than Curry/Howard based provers like Coq, Agda and Lean.

One may wonder if there is a correlation between size of TCB and error rate in widely used provers?

Yea, I also would want to question the conclusions in the article. Was the issue that they couldn't unlock the iPhone, or that they had no reason to pursue the thread? To my understanding, the Apple ecosystem means that everything is synced together. If they already got into her laptop, wouldn't all of the iMessages, call history, and iCloud material already be synced there? What would be the gain of going after the phone, other than to make the case slightly more watertight?

I built dttb (DateTime TraceBack) because I was tired of coming back to my server after a night of running long crawling/training/trading, seeing a crash, and having no idea when it happened.

Was it 5 hours ago? Or just 5 minutes ago?

Python tracebacks are great, but they miss one crucial piece of information: TIMESTAMP

Before:

Traceback (most recent call last):
...
Error: something wrong

After:

[2026-01-28 14:30:15.123456+08:00]
Traceback (most recent call last):
...
Error: something wrong

No. Think about it for a second: you're a journalist being investigated to find your sources, and your phone says you mainly check sports scores and send innocuous emails to "grandma" in LLM-speak? It's not going to fool someone who's actually thinking.

I build in the ATmosphere because I want to effect change. AP was hostile, Nostr is for crypto bros. The @dev community is one of the strongest pieces and attractors

One way I like to think about how the protocol is different is that they made a giant event system for the public content and then let anyone plug in anywhere they want

Is the knowledge of which finger to use protected as much as a passcode? Law enforcement might have the authority to physically hold the owner's finger to the device, but it seems that the owner has the right to refuse to disclose which finger is the right one. If law enforcement doesn't guess correctly in a few tries, the device could lock itself and require the passcode.

Another reason to use my dog's nose instead of a fingerprint.

Agreed. I hate to say it, but if anyone thought this train of thought in management was bad now, it's going to get much worse, and unfortunately burnout is going to sweep the industry as tech workers feel evermore underappreciated and invisible to their leaders.

And worse: with few opportunities to grow their skills from rigorous thinking as this blog post describes. Tech workers will be relegated to cleaning up after sloppy AI codebases.
Show HN: Editor for perfecting your YC App. Multiplayer w/ Durable Objects. OSS.
by bsenescu | 2026-02-04 16:42:29+00:00
I originally built this because I wanted a way to practice answering questions I get often when talking to potential users. I got carried away and built a full multiplayer text editor with AI review...

Here are all the features:

- Use templates like the YC App questions.

- Create pages for your pitch to investors, customers, or friends and family.

- AI Review with customizable prompts

- Practice mode (Mobile Friendly): answer questions verbally, get transcriptions, and self-rate your performance

- Share pages for real-time multiplayer editing

- Authentication & User Management via Every App / Better Auth

This was a cool project for working with Cloudflare's Durable Objects which support serverless websockets & multi player. It was pretty hard to get this working well, I see why Tip Tap has a SaaS for that lol

You need to look at use-case alignment as well as performance.

Apache Pinot, Druid and Clickhouse are designed for low-latency analytical queries at high concurrency with continuous ingestion. Pinot is popular because of it's native integration with streaming systems like Kafka, varied indexing, and it's ability to scale efficiently. They're widely used in observability and user-facing analytics – which are how “real-time analytics databases” are commonly perceived today.

Exasol (and SingleStore, Snowflake, BigQuery, etc) are more focused on enterprise BI and complex SQL analytics rather than application serving, or ultra-high ingest workloads. It performs well for structured analytical queries and joins, but it’s less commonly deployed with the user-facing analytics or high volume usage.

A good rundown from Tim Berglund in this video here:

I don't think it will ever really happen because of ownership.

Sure this is awesome now and maybe he shipped it in a week using AI or something, but he now owns a critical part of his wife's business. 5 years from now he is gonna be working 50/hrs a week and not want to deal with this project he barely remembers even doing, whenever an SSL cert goes bad or the CC he was paying the server bills with expires or actual bugs happen he is on the line for it.

It is lame to let family/friends pay $20/mo for something you could build in a few weeks, but they will own the product forever, I don't want to.

This is the same story where every time you hear about some democratic run city/state implementing policy, everyone makes it out to be a step in the goal to get to 1984 Oceania.

This legislation is basically like a gold star on some politicians report card about preventing gun deaths. The impacted groups are allways gonna be niche, but it looks good to the overall public.

If hotels, or google, or travel websites wanted people to book programmatically they would have an api.Remember when Google search had an api? In the end the human is responsible for the purchase. I think when the dust settles, AI will offer a "do you want to purchase?" and then the human will press the button. Or ChatGPT or somebody controlling the last step will have that button, and services will accept it (like Instagram) because it brings business.

An interesting option for fretted instruments is to build it with 12 regular frets per octave, and then add temporary extra frets if you want to make specific notes more in tune for the key you are in.

This was common for lute players in the Renaissance and Baroque periods. Lute frets were usually made of the same material as strings and were tied on around the neck, so adding an extra full width fret was not hard.

Of course being tied on lute frets were also movable, so they could also reposition the regular 12 frets instead of adding extras.

Instead of tying on an extra full width frets another common option was partial frets. They would glue a piece of string or wood under a specific string, to just give an option to play one note with either the regular fret or the more in tone little fret (called a "tastino" (plural is "tastini")).

In this video [1] Brandon Acker uses a guitar that his luthier friend was building that had not yet had the frets installed to demonstrate with lute style tied on frets some different 12 tone tunings, then demonstrates using tastini to improve specific notes, such as little fret on the G string a little before the first regular fret so that G♯ and A♭ can be different notes.

The tastini he uses in the video are simply pieces of string held on with a piece of tape, so quick and easy to add and remove.

Show HN: Guess the Common Word Game
by vunderba | 2026-02-04 16:44:20+00:00
There’s an old word game where one person comes up with three words:
sign, watch, bus.

The other person has to think of a common word that forms compound-style words with each of them:
stop.

Which forms: Stop sign, stopwatch, bus stop.

My siblings and I used to play this game to while away the hours on long car rides. Rather surprisingly I couldn't find an online equivalent so I put this one together.

> Instead, the electorate should be narrowed to property owning people

Define "property owning", presumably you mean land or a home (would an apartment be enough without any real rights to the land it sits on?). This definition would end up disenfranchising most young adults and probably a majority of the members of the military (the military is relatively young, and young enlisted folks are housed in dorms, and if they move frequently often don't bother buying homes because it just doesn't make financial sense).

Exciting to see Apple making agentic coding first-class. The "Xcode Intelligence" feature that pulls from docs and developer forums is powerful.

One thing I'm curious about: as the agent ingests more external content (documentation, code samples, forum answers), the attack surface for prompt injection expands. Malicious content in a Stack Overflow answer or dependency README could potentially influence generated code.

Does Apple's implementation have any sanitization layer between retrieved content and what gets fed to the model? Or is the assumption that code review catches anything problematic? Seems like an interesting security challenge as these tools go mainstream.

I think it’s interesting to reconsider the idea of having floating widgets in an era of powerful CPUs/GPUs and multi-monitor setups.
Personally, I love having my “widgets” active on the third monitor (the one I dedicate to “frivolous stuff” when I’m not drowning in open windows). I always keep two “old-school” draggable widgets active: a "macro keyboard shortcut remider" and a “diabetes monitoring dashboard” (unfortunately, that’s my cross to bear). I also always keep VLC running in a super-minimized state (web radio).

It seems to me like a smart way to always have certain “useful things” at hand.
If I could achieve the final combo and get back an email ticket system identical to the one The Bat! provided 1000 years ago, I’d be really happy.

Total pipe dream. They can't take away your servers, but they can imprison you until you provide access. And SpaceX would still fall under the laws of whichever country it's based in. If lawful access is really a problem, laws will be written to make it SpaceX's problem. Relevant XKCD: https://xkcd.com/538/

Nah, Musk put out a public challenge in January asking anyone able to generate illegal / porno images to reply and tell him how they were able to bypass the safegaurds. Thousands of people tried and failed. I think the most people were able to get is stuff you'd see in an R-rated movie, and even then only for fictional requests as the latest versions of Grok refuse to undress or redress any real person into anything inappropriate.

Just to be upfront, i've gone from one of the naysayers to a modest fan after spending some time using Claude Code on nights/weekends with tasks that I know I can do and how long it would take me in order to get an idea of productivity gains possible with the tool. So far, the money i've spent was worth the results i got.

However, it's shocking to me the blinders people have with these things. Security is supposed to be front and center in our industry with everything we build and do. I thought that lesson had been learned and learned well over the past 30 or so years of life on the web. People are going to get seriously burned and the only answer to them is going to be "well you should have known better". For a fishing analogy, Barracuda are circling just out of visual range biding their time but the strike is inevitable.

If you're using these agents, spend some time attacking them and see what you can get them to do that you thought would be impossible by default. If you find something say something, we're basically having to re-teach the whole Internet basic information security again.

I was once closer to s free speech absolutist, but this has always been where that discussion leads. The lines were clearer decades ago because someone who interacted with CSAM was closely involved and their harm was easier to see in totality. Over time the gap between people who caused that harm and those that think they are not hurting anyone has widened. With AI it caused many of those that thought it was acceptable to consume illegal content to put another layer between their victims and offload the moral baggage.

I wasn't thinking of going THAT far. Northern Canada/Alaska is in the arctic region, so build the line some thousand miles down to the sunny parts of Canada/USA and call it done. Not like this is particularly hard, probably not even that expensive, compared to a million satellites/future space-debris. Greenland would probably be also a good location.

The Problem

When AI agents talk to each other in automated pipelines, nobody monitors the conversation. Agent A might say a project costs $1,000. Agent B says $5,000. Neither knows about the contradiction. The wrong number reaches the customer.

Worse: agents fabricate citations that look real. They invent URLs, DOIs, and paper references. They start confident and silently become unsure. One agent's hallucination becomes the next agent's trusted input.

The Solution

InsAIts V2.4 monitors every message between your AI agents and catches problems before they propagate:

5 Hallucination Detection Subsystems:

- Cross-agent fact contradiction tracking (Agent A vs Agent B)
- Phantom citation detection (fake URLs, DOIs, arxiv IDs)
- Source document grounding (verify against your reference docs)
- Confidence decay monitoring (agents losing certainty)
- Self-consistency checking (contradictions within one response)

Plus 6 more anomaly types:

- Shorthand emergence (real words become abbreviations)
- Context loss (topic switches mid-conversation)
- Jargon creation (made-up acronyms)
- Anchor drift (diverging from user's question)
- LLM fingerprint mismatch
- Low confidence detection

Key Features

- Open-source core (Apache 2.0) - anomaly detection, hallucination detection, forensic tracing, dashboard, all integrations
- 3 lines of code to start monitoring
- Privacy-first: All processing runs locally on your machine
- Works with any LLM: GPT-4, Claude, Llama, Gemini, Mistral
- Choose your Ollama model: `insAItsMonitor(ollama_model="phi3")`
- Framework integrations: LangChain, CrewAI, LangGraph
- Ecosystem exports: Slack alerts, Notion, Airtable, webhooks
- Forensic chain tracing: Trace any anomaly to its exact root cause
- Premium features included via pip: Adaptive dictionaries, advanced detection, auto-decipher
- 75+ automated tests covering all detection heuristics

Who Is This For?

- Teams building multi-agent AI systems
- Anyone using LangChain, CrewAI, or LangGraph in production
- Companies where AI accuracy matters (finance, healthcare, legal, e-commerce)
- Developers who want visibility into AI-to-AI communication

Pricing

- Free: 100 messages/day (no API key needed)
- Lifetime Starter: EUR99 one-time - 10K messages/day forever
- Lifetime Pro: EUR299 one-time - Unlimited forever

First 100 users per tier only.

Not sure why this is getting downvoted, but you're right — being able to crank out ideas on our own is the "killer app" of AI so to speak.

Granted, you would learn a lot more if you had pieced your ideas together manually, but it all depends on your own priorities. The difference is, you're not stuck cleaning up after someone else's bad AI code. That's the side to the AI coin that I think a lot of tech workers are struggling with, eventually leading to rampant burnout.

Frankly, that's a question of values, not of process.

I'm not championing any particular set of values here (except, perhaps, that I'm implying the values of doing impartial science and of inclusive, rational public discourse).

I'm saying that public debate ought to be had to litigate that question, and that hard data should feature prominently in that debate. That is not something we'll do if we assume in either direction that "environmental regulation is always good" or "environmental regulation is always bad." I'm saying both kinds exist, and that apart from hard data we can't confidently know one from the other, which means we have to assess and re-assess. I'm not pre-registering an opinion on which side of any particular debate should win, or why I think that instead of the opposite.

Not exactly. Reddit always took down CSAM (how effectively I don't know, but I've been using the site consistently since 2011 and I've never come across it).

What Reddit did get a lot of negative public publicity for were subreddits focused on sharing non-explicit photos of minors, but with loads of sexually charged comments. The images themselves, nobody would really object to in isolation, but the discussions surrounding the images were all lewd. So not CSAM, but still creepy and something Reddit tightly decided it didn't want on the site.

You don't put it in a standard orbit, you put it in a polar orbit with near 100% suntime ... obviously.

Obviously you use the backside of the massive area of PV you need, for an equally massive area for HOPG radiator films with condensor coils (because obviously you use heatpumps for cooling, not pure liquid).

Consider the obvious ways you'd actually do it, not the most naive ways.

The GPU pods obviously won't weigh the same as a terrestrial rack. Space based solar arrays obviously don't weigh the same as your hail and storm resistant panels on your roof (see ROSA, but there might be another 10x weight reduction if using flexible solar in tension from rotation). Noone cares about a couple 100 ms extra for first token.

Solar wind and drag are in my opinion the biggest issue. Problem : it's a giant surface catching drag and solar wind. Solution : it's a giant solar sail. Controlling the angle of PV for useful thrust, that's never really been done for a satellite.

Why would they bother to build space data center in such monolithic massive structures at all? Direct cables between semi-independent units the size of a star link v2 satellite. That satellite size is large enough to encompass a typical 42U server rack even without much physical reconfiguration. It doesn't need to be "warehouse sized building, but in space", and neither does it have to be countless objects kilometers apart from each other beaming data wirelessly. A few dozen wired as a cluster is much more than sufficient to avoid incurring any more bandwidth penalties on server-to-server communication with correlated work loads than we already have on earth for most needs.

Of course this doesn't solve the myriad problems, but it does put dissipation squarely in the category of "we've solved similar problems". I agree there's still no good reason to actually do this unless there's a use for all that compute out there in orbit, but that too is happening with immense growth and demand expected for increased pharmaceutical research and various manufacturing capabilities that require low/no gravity.

I've been using Xcode since it was Project Builder. It has improved in many ways. And since the advent of the App Store, the insufferable/inexcusable nightmare of "signing" has vastly improved.

Most of the problems I encounter now resulted from the fiasco that is SwiftUI. I used to really enjoy development, and built a few mobile apps singlehandedly... even at a well-known company or two. But now I'm struggling to get one chunk of functionality at a time done on a from-scratch app, because SwiftUI and the underlying "reactive" paradigm were so poorly conceived and defectively implemented. Development is now miserable drudgery, and I never feel confident about the result. The absurd gymnastics to trick the UI into doing what you want; and the hypocritical, conflicting edicts for Swift and SwiftUI... it all barely hangs together.

The fact that Apple rolled out a new UI toolkit that didn't support the most fundamental paradigm in mobile applications, a stack of progressive views for the user to proceed through, tells you how far off the rails they went since introducing the original and solid SDK.

And testing is going to be a nightmare... or simply futile.

Not mentioned, but something I would like/expect would be to have some kind of editor integration... VS Code remote extensions, as an example even... You can be in a remote code server with your local editor and terminal tab(s) within said editor on the remote system.

I realize this is using other interactions, but I'd like a bit more observability than just the isolated environment... I'm not even saying VS Code specifically, but something similar at the least.

Yeah, our baloon was recorded by WSPR eeceivers thousands of kilometers away when it crossed the arctic circle for a day - we wpuld have no data if it were dependent on line of sight or even just flying over inhabited territory.

And indeed, the relions take minures to send a couple dozen bits of data. But the modulation is done in such a clever way, that it does not really matter - you know ehere the probe with your callsign was, how high, ground speed, temperature and panel volatage. There is quite agressive heuristics applied (eg. different precision for different altitudes as you don't really expect it to stay low for any ammount of time and survive, position via grid squares with course position still available even if you have incomplete data from a relation) so the few dozen bits are enough. :)

It is all super clever and hats off for those who developed this system. :)
