Oh, this attack would be a useful tool for e.g., identifying whistleblowers that travel a lot (e.g., in academia, military). If you know their Signal ID, you could send them images from time to time and then compare their coarse locations with travel information for a number of suspects.
Well, let's imagine an object that has some Platonic motion of 0.2c directly away from us, but it's so far away that spatial expansion boosts its velocity to 1.1c.

At time 0 it emits a photon toward us. One year later, it's 1.1 light years farther away. The amount of newly-created distance between us is 0.9 light years. Some of that was created behind the photon, but I'll ignore that and just assume that all of the new space got in the photon's way.

Over that one year, the photon has traveled 1 light year towards us, and only 0.9 light years of that distance was new. So it's gotten closer to us by (a little more than) 0.1 light years. This rate will accelerate over time.

The object is still visible at the point where it emitted that photon, even though its velocity exceeds the speed of light.

I think it will ultimately become invisible, though.
TikTok Emerges from Shutdown Without ByteDance's US CDN
You’d be surprised at how adept the younger generation can be, especially those who’ve grown up with technology. As tech evolves, so do they. There are kids who genuinely apply themselves, and because they’ve been immersed in this environment, it’s practically second nature to them. I remember the late 1990s: I was young, but more than anything, I was curious about how things worked, I had the luxury of time, and access to technology to explore it. I started coding in C++ when I was around 13, and honestly, I still feel like I started too late.
Could you recommend a tiny language model I could try out locally?
Ask HN: Is the training material the new AI moat?
DeepSeek R1 claims to be trained with 14.8T high quality tokens, without further info on the contents. Meta claims 15T tokens from public sources with undisclosed filters.

Are such datasets needed to train these models accessible to any company? If one wants to get such dataset, let's say in some non-AI hotspot country, like India or Brazil, would it be possible in the first place? Or is special corporate access needed, as these datasets seem to be kept private and undisclosed for all new models?

NFC tags cost about 20 cents and they are easy to use, tied to a place, etc.

I've done a lot of thinking about cyberphysical art that used to look like

Notably with the QR code on the back I found people didn't understand the branding of the card and had to flip it over to know the affordances it offers which didn't work when the card was stuck to the wall, as in

https://bsky.app/profile/up-8.bsky.social/post/3lbftgz6kok2c

I researched NFC tags as an option here and bought a 100 pack and a Sony FeliCa reader but found the problem of "communicating the affordance is available" was much worse, there's no standard logo (except one that belongs to the banks that they wouldn't give me permission to use) and not much awareness. I was irritated that NFC support is limited in iPads, for instance. So I stuck with QR codes that people understand.
Well you've disproven my point. Good work.
I love alpine. They make a great base for small and efficient docker containers.
It’s a pretty interesting point.

If a large fraction of the population can’t even hold five complex ideas in their head simultaneously, without confusing them after a few seconds, are they literate in the sense of e.g. reading Plato?
I mean "then they figure out how" and "make a new account" are each doing quite a bit of the heavy lifting here.

Using Activision as the example, when they do a mass ban after you've been cheating for 4 months straight how exactly are you going to figure out how it happened?

Isn't the whole point of the ban that it's not as simple as just "make a new account?" Isn't it tied to the PS+ / XBox Gold membership, or even the physical hardware?

Ask HN: ”Incognito Mode" for Your Terminal?
As an example, here’s a recent write up on how to build a tiny bootable Linux:
https://blinry.org/tiny-linux/

Like many of us here, I sometimes want to try out a tutorial like this briefly and then forget about it.

But just like the Author of the example story, you often end up installing additional packages and libraries to your system that become useless the second you close the browser window.

In the web, when you want a temporary browsing session, you fire up Incognito mode and then just close the window to clear history and cache.

In that Incognito window one can still use old bookmarks, stored passwords, access history etc. (Maybe this is a Safari Private Browsing thing only?).

Anyways, it has some conveniences from your base browser setp so that makes usage and alternarive logins in the Incognito window are a bit easier.

What I’d like, is to take this Incognito window concept and bring it to my terminal:

Open a terminal window into my current system, have all the access rights and history my normal shell has, but any installed packages and system file changes from the shells in that window will ”undo” / rollback on terminal close.

I would use it in this article example to:

- start a new Incognito window

- create a project directory under home

- install random packages to build kernel

- install qemu to run it

- try to get the kernel working in qemu

- might have multiple shells open in the terminal window, all share the temporary environment

- finally finish up and close window

After the session, the project folder in my home directory would stay intact but changes to my system files would be ”removed”.

My question is:
How you’d you achieve this now, without special shell/terminal software support?

Note that the convenience of sharing my current system environment as the basis is the key here, so just creating a separate preconfigured VM is not the goal.
Sure, there's obviously a scale.

I'm not about to divide 54,432 by 7.6, even though I was taught how to. I'll pull out my phone.

On the other end, I'm not going to pull out my phone to figure out I owe you $0.35.

I think the point I was trying to make still stands.

Show HN: Couples therapy with AI and Therapists – all in the same chat room
We build this feature that’s a first in the mental health space: Couples Therapy in a shared chat room with AI and a Licensed Therapist.

Here’s how it works:
* Three participants in one chat room: You, your partner, and an AI therapist assistant.
* Therapist oversight: Licensed therapists regularly review the chat, guide the AI, and update therapy plans to ensure real progress.

Why we built this:
A user wrote to us:

"Hi

I want to use the website for couples therapy and go for the £80 a month sessions. I was curious to know if there will be a way or method so me and husband can use the chat at the same time and have our own labels such as names, so whenever we have a session the ai can distinguish which message is from who without having to specify it each and every time. I hope it makes sense.

Kind regards
"

We build this feature in 2 days (awful lot of refactoring to accommodate additional user in the chat room) and we have this user as paid user.

While many people have used ChatGPT for individual therapy, this concept of couples therapy as a shared experience is entirely new.

How Cutthroat Should Founders Be?
We’ve seen multiple cases of founder break-up or board/founder conflict due to one side being a “slave-drive” vs the others “not pulling the weight” (in their own words).

It’s not a debate about low-performing companies or those that overemphasize vanity goals or metrics. I’m also not
debating 30 hour vs 100 hour work weeks. It’s a trade-off between employees working 50 hours work weeks, vs pushing for 80-100 hour work weeks with mandatory bottom quartile employees fired at every review. Both approaches can create exceptional companies.

1. The Cutthroat Culture: “Dominate”
At its extreme, the cutthroat approach prioritizes performance over everything else.
High-Performing Examples: Uber under Travis Kalanick, Elon Musk’s Companies such as Tesla and SpaceX, and TEMU’s
meteoric rise: In just three years, TEMU achieved a $34 billion IPO. Its employees work 350+ hours per month, operating in an environment where team
battles determine survival—winners are rewarded, losers are fired. This relentless approach has led to unparalleled speed and efficiency
These companies don’t just survive—they dominate.

2. The Nurturing Culture: “Building People to Build the Company”
In contrast, some companies prioritize loyalty, stability, and growth when they drive company performance, even if it
means slower progress in the short term. They believe investing in people creates lasting success.

High-Performing Examples:
Dropbox: the early days of Dropbox are full of the smartest people from MIT, self-motivated to do their best work. They are also served with the best meals and a coach for each executive for their growth. Not many people are managed out and given most people are very smart, they generally can grow into a better self. Costco: This retail giant pays its employees above market rates and fosters a culture of respect and stability. The employee base is long-tenured employees and company consistently profitable.

The Core Trade-Off: Domination vs. Stable growth

Both approaches come with inherent risks, for every employee burning out for type #1 companies, probably just as many are checked out under #2.
The critical question is: Which error is more acceptable? A higher percentage of employees burning out because they are pushed too hard, or a higher
percentage of employees checking out because they are not pushed hard enough? At early stage, would we rather have a shot at $100b company knowing it might explode to zero on the way or a stable $1b company that’s almost a sure bet? Both are likely the top 1% but if you have the luxury of making a pick, which would you rather pick?

We’ve invested in companies under each model. But founders have only one shot. Which one do you choose?
The real attack is that a law enforcement agency can trivially subpoena CloudFlare with the attachment URL they will hand over the IP address of the recipient of the image along with whatever other requests they made through the CDN which can pretty precisely and rapidly de-anonymize you.
Right — I totally understand why things are the way they are using the tech industry startup model. But using that model is relatively new, and adopting it not a prerequisite to starting a tech business, even if that’s the only way people do it these days, generally. Becoming a monopoly immediately in some market is the goal of someone that wants to become the monopoly immediately in some market. It’s neither a requirement of, nor mutually exclusive of having a good idea that you want to turn into a business. That business goal might be easier in technical businesses, but it doesn’t seem to make better or more sustainable companies. “That’s the way it is done” is usually the worst reason for doing something. It doesn’t mean it’s bad, per se, but it definitely doesn’t mean it’s good.

these things take time -- first, industry specific tools leveraging LLMs have to be created and take root; then companies slowly implement those by freezing new hires and not filling positions that empty, reducing their costs and leaving the rest of the employees to pick up the slack because they are now "more productive" thanks to AI

I can just give the logins to someone else. My current setup is a workable, optimal, but not clean solution to the problem.
I seem to be going in the opposite order lol—I've been getting my facial hair removed for almost a year now, but am only barely starting to become comfortable with the idea of actually transitioning. And if I did transition, I think I'd likely only come out socially to a very small group of people until I'd also transitioned hormonally! Perhaps my priorities are all backwards...

I read your linked post and enjoyed it—I've heard vaguely similar sentiments expressed before by some of my trans friends. It's like that RuPaul quote: "We're all born naked, and the rest is drag."

I hope you have a nice day, and thank you for the well-wishes :)
You know… when I took the SATs I surprised myself by scoring higher on verbal than math. But it has explained so much about my subsequent interactions with my fellow nerds. So many people don’t realize prose is part of their job description and it shows. Doubly so for mathematicians. I feel like I’m taking crazy pills until I have to talk to customers or consumers and I see how they think we are all collectively nuts. They’re not wrong.

In software, restating the problem or the bullshit plainly is usually the first step to eliminating or mitigating it. George Carlin and his rants about softening words until they mean nothing comes to mind all too often.
I used to work for a company that bought off cuts from this plant and the static that comes off of these rolls is scary. I heard this story years ago and no one in our plant had a doubt about it being true because 3M ran enormous rolls.

I also hate the games they play with labeling such as "no sugar added." Bought a cherry pie from a local market labeled "no sugar added" thinking it was going to be extra tart only to take it home and taste sugar. Reading the label it listed sugar alcohol which I learned can cause gas and bloating in some people, which I soon found out. Once slice had me doubled over with gas pains a whole night and shit my brains out the next day. I got my money back for that piece of garbage pie. I want to punch whoever thought no sugar added means fuck all...
Yes. It's a Windows application for engineers. Price is a few hundred dollars per seat. The support load is pretty stable. People often have a few issues at first or when trying to do something novel, then they're fine. They have to update it themselves and occasionally I'll hear from a customer still using a 10 year old version but usually when they ask for help, they're already on the latest version, somehow. Nobody has complained that it doesn't auto-update or nag them. I make about the same money as a regular job.

All my customers are extremely pleasant to deal with. You hear horror stories about angry or entitled customers but mine are always polite and respectful. When something doesn't work right, they often act like it's their own fault. Even when they want a refund because they don't like it, they ask nicely. I suppose they know I'm a one-man-band so their expectations are a bit lower than for a giant company. But also, engineers don't seem to be dickheads generally, at least not when they're at work.
They dismiss it for the same reason people dismiss disruptive new technology - they are uncomfortable with it. It's a signal (ha) that the threat is very real.

First dismiss it and see if the problem is still there in the morning. Hope that before then, someone finds a reason it's not a problem. Anyone?
you sound like me, I was a little younger though ... aimbots, wallhacks, esp, textures, radar, it was all intriguing and I hated encountering cheaters in CS 1.4 and 1.5. I also began dabbling in writing bots around this time, as POD Bot was awesome!

php had also been a thing of mine, I spent many months in DALnet and EFnet #php. Primarily around the time of v3 prior to v4's big launch...
There's something magical about ChatGPT giving you a mostly-wrong answer.
IMO the stress is different. In startups you own things a lot more personally, and depending on how you handle stress that can be more challenging than the stress at big tech.

Hours can very much depend on the big tech and startup individually, but big tech is certainly moving in the wrong direction here, and in the typically big corporation/enterprisey worst way possible (increased employee monitoring, shallow and manipulable KPI's that act more as perverse incentives than actually improve anything and that increasingly show the disconnect between upper management and engineers)

> And the work is much narrower and boring. The system is designed to make people into commodities and make you do work in the way that most benefits managers senior to yourself. Solve this narrow piece of a problem using this specific method alongside 5 other people doing other narrow pieces, versus a startup where you can just own the whole thing and iterate it faster.

I agree and its my primary complaint/dislike for my job. I would love to, and probably will change to a startup or other job with a company I actually care about and a role I find valuable, but I expect the pay to be a significant drop when I do. Until then I'm leaning on the salary to reduce the amount of time I need to work overall significantly and putting in my time so to speak.

For now big tech is winning, but if startups and employee equity start having the potential payoffs they used to then it changes the balance of the above equation by quite a bit.
Proxmox Datacenter Manager
Building a Github-specific CI pipeline similarly transfer it into a set of executable steps.

The only difference is that you are now tied to a vendor for executing that logic, and the issue is really that this tooling is proprietary software (otherwise, you could just take their theoretical open source runner system and run it locally).

To me, this is mostly a question of using non-open-source development tools or not.
> In reality, the individuals that compose one side are different from the individuals that compose the other side in predictable and problematic ways.

Predictable is where we disagree strongly.

I think there's more diversity than unanimity at the individual level in both parties.

In the sense of what people say they believe around a dinner table, not what they passively nod their heads to at a rally or while watching partisan news.

Which is ironic, given it's increasingly a trope on both sides that the other is sadly monolithic and all marching in lockstop to their leader's tune.

Republicans complain about Democrats being like this; Democrats complain about Republicans being like this.

PS: "Problematic" is a terrible non-word. Surely there's a more descriptive adjective to be used?
I mean right now just seems to be one of those business that one pays to put a logo of a nice green checkmark or a tree to make your product seem more legit and ethical

Sure it’s nice to push bunch of nice UI patterns but I imagine most of the “certified” products weren’t going to be attention hogs anyways. A positive outcome from something like this would be if governments started requiring these kind of certifications like they do for accessibility.
A percentage of them are.
> My guess is that this happens in nearly all large-scale production systems but goes mostly unobserved.

Not unobserved. Unremarked maybe? It's expected behavior that leads us into personification of systems e.g. calling ships 'she' or talking about temperament between similar machines on a line.

the only thing that I've seen growing that I hope is pushed back is the growing number of jokers. I see people posting here like it's reddit or slashdot. it's not, and that's part of what makes it valuable. every joke comment is a loss of signal in the forum.

jokes are great, but unless it's a joke that has some truth squirreled away in it that's worth knowing and well transmitted by the joke, it shouldn't be here. especially on its own. little joke at the end of a long relevant anecdote? great. just replying because you had a moment of wit you'd like to share? think twice and don't, please.

there are plenty of places to be a comedian. I enjoy it myself on more than a few. but I would prefer it not be here.
Context: To curb endless link spam, there has been a longtime rule that Twitter is the only social network users could link to when reporting news from NFL insiders.

Even before the election, the transition from Twitter to X has been creating problems. First, the insiders have begun moving away from X and onto other networks. And more importantly, you now have to have an X account to see anything on X. So its usefulness as a link is pretty dead.

> less low hanging fruit on the product side. Any given opportunity is more likely to have other, well-resourced, folks chasing it hard.

I think this is the biggest factor that actually affects the fundamentals of selling tech. To my eye, every other aspect is some form of Gordon Gecko business insanity and/or VC people looking to stoke egos by making people with good ideas feel like big shot executives while figuring out how soon they can throw it all in a juicer and extract a bunch of cash.
I believe DeepSeek models do split numbers up into digits, and this provides a large boost to ability to do arithmetic. I would hope that it's the standard now.
