Show HN: I built an app to help vibe coders get users
by bytet3ch | 2026-01-29 16:29:50+00:00
For most of us, getting users still takes real work.

Short form content on TikTok and Reels can be one of the fastest ways to get real users, but DM’ing content creators on IG or TikTok barely works. Low response rates and a lot of manual work.

So I built Collab Only, a matching app where vibe coders and content creators match by niche and goals, then chat instantly to collaborate.

I launched a few days ago, and it has already helped me connect with content creators faster than cold DMs.

I'm looking for feedback from this community.

Have you tried working with content creators to get users? What other approaches have worked for you?

Brightness down, LAN card disabled (the media sense on RTL cards sucks about 1.5W with no cable plugged in, wtf? Thats more than the Wifi needs)

And powertop (great piece of software, thanks Intel) tuned to the max + powersave scheduler.
All that on Windows or KDE results in about 4-5h of battery though. So fbdev must be somehow really frugal.
Ask HN: How are you preventing AI-driven "brain-softening"?
by _aleph2c_ | 2026-01-29 16:30:05+00:00
I’ve noticed a trade-off in my daily workflow. An LLM is basically a "Senior Dev in my pocket" for almost any technical niche. It’s an amazing resource for clearing blockers, but I’m worried about the long-term cognitive cost.

There is a fundamental difference between having a senior dev tell you the answer and "drilling" the keystone-concepts yourself until they become muscle memory. One gets the things done in a hurry; the other builds self-sufficiency.

I’m starting to feel the "brain-softening" effect where I reach for the prompt before I’ve even tried to orient myself in the problem.

How are you guys handling this? What are your personal guardrails, disciplines, or "hard-mode" rules to ensure you’re using AI as an accelerant rather than a crutch that rots out your technical intuition?

> But even if that was the case, is there any value for a receiver to be receiving those?

Yes, radio propagation is an entire academic field to be studied :)

In addition, if you have enough receivers you can use that to run something called MLAT [1] to also pick up GA aircraft that just have a transponder but no GPS. The more the merrier.

Any chance you can prevent the left hand navigation floating widget of 10 bubbles (no idea what it's called) from rendering on top of the actual content? It obscures the text that I want to read, very irritating. [Edit: I see, it works at 100%. But my default zoom is 110% or 120%. Zooming seems to break your layout.]

To add on this, ethnic heterogeneity (and ethnic enclaves) is one of the shallowest forms of diversity. If you examine the diversity regarding district characteristics and architecture, shopping options, subcultures, etc, many homogenous cities like Tokyo or Hong Kong are far greater and accommodating than London in diversity.

And I would say that one reason for that is the elements I mention is something an individual can take seriously and integrate into their own world, while enclaves stay perpetually from the vantage of exoticism rather than integration.

Eh, you're overselling it. Even in a hypothetical world with a 12 hour train trip, it still loses to an 8 hour plane trip.

You're losing an entire day on the train. You still have to deal with luggage pains, now you're eating on the transportation which will be inferior, and will have similar problems with last mile transportation.

Flying is currently not a great 8 hour experience, but it beats losing an entire day. I can do LA to NY for a weekend trip. (I personally wouldn't but there are some that would for sure)

Trains can and do make sense even in the US, and we do ourselves great harm by underinvesting in them, but there will always be a place for plane travel.

Back in the 80's and 90's he was pretty well known for noting that if you owe a bank enough money, it is in the bank's interest not to let you fail.

My guess is that it also helps to owe lots of money to lots of banks at the same time. That way when one goes after you, the others will help you out or risk losing their money, too.

Completely agree, I'm looking at pretty much all software this way nowadays.

We've all been around long enough to know that "free" VC-backed software always means "free... until it's in our interest to charge for it". And yet users will still complain about the rugpull in 2026, no matter how many times they've been through it. "Fool me once, shame on you"

Hand-picked by Noem, so yeah.

https://en.wikipedia.org/wiki/Madhu_Gottumukkala

> In April 2025, secretary of homeland security Kristi Noem named Gottumukkala as the deputy director of the Cybersecurity and Infrastructure Security Agency; he began serving in the position on May 16. That month, Gottumukkala told personnel at the agency that much of its leadership was resigning and that he would serve as its acting director beginning on May 30.

I don't have as much experience as some. Just 4 years leading RevOps in B2B Enterprise Sales. But this is an issue that comes up over and over. Methodologies like MEDDPICC can help, but the eagerness to close the deal sometimes takes over. Even when you know you're not talking with the right person, you just keep going.

We've reached a good point where AEs do their best to involve the decision-maker in the sales process ASAP, but it’s still happening.

I recently spent several evenings re-working all of my colours across all of my computers and screens; terminals, IDEs, etc. Ultimately, despite using the same tools, and always dark mode, across all of my machines, the setup for each was different.

I think it's safe to set a standard colour-set so that it's immediately usable, but beyond that, a user should be customising to their requirements.

Perception differs among people; many of the colours OP listed as unreadable, were barely an issue, bright yellow being the only one I could unequivocally agree on. Perhaps display type, configuration and colour calibration is an important factor, as well as individual perception, ambient conditions, brightness levels, contrast, and perhaps even more variables have a significant effect.

I've also learned, since adding an OLED Monitor to my desk alongside the IPS ones, that it's possible to have too much contrast; brightly coloured text alongside pixels that are literally off can be just as problematic to read at times, as low-contrast.

Again, those are just assumptions you make without further understanding of a great number of things.

If you looked at US infrastructure and based the population we should have on how a developing nations population works, then you'd come up with a number like 750 million to a billion people... because 6 to 10 people live in a house, right? FYI, average US household is 2.5 people.

Simply put you cannot make any of your assumptions without more knowledge.
by whynotminot | 2026-01-29 16:33:17+00:00
I would wager the main reason for this is the same reason it’s also hard to teach these skills to people: there’s not a lot of high quality training for distributed debugging of complex production issues. Competence comes from years of experience fighting fires.

Very few people start their careers as SREs, it’s generally something they migrate into after enjoying it and showing aptitude for it.

With that said, I wouldn’t expect this wall to hold up for too long. There has been a lot of low hanging fruit teaching models how to code. When that is saturated, the frontier companies will likely turn their attention to honing training environments for SRE style debug.

They're not aiming at replacing SQLite-in-C with SQLite-in-Rust, they're doing this so they can implement more additional functionality faster than with C's chainsaw-juggling-act semantics and the inability to access the proprietary SQLite test suite.

> So like idk how that would make sense for them to be the same range of population when China seems way more overcrowded.

Different population distributions. In particular, the population of China is concentrated in the eastern half of the country, with very few people living in the western half. Contrast to Europe, which from what I understand is more evenly spread out.

Exactly

And then neo nazis go around telling susceptible people "Look, Hitler's detractors think he had 12 fingers, just look at any picture of him, he clearly only has 10. You're gonna trust people that stupid to be honest about him? To know anything about him?"

Disinformation feels good in the moment, but is immensely damaging overall. Even the people who believed he had 12 fingers will feel betrayed and question everything else when they one day learn he actually had 10.

More like by the moon.
No landing.
Not even orbiting.
Party like it's 1966.

If you feel the 'by' vs 'to' distinction is pedantic,
consider the following thought experiment.
A friend of yours invites you to go with them to another friend's house.
A bit later, sitting in the passenger seat of their car,
you see your friend's house come into view as you turn down their street.
What's your reaction as you're sitting there and instead of stopping and parking,
your friend continues past the house and starts heading back to your house?

I bought an E-Bike two years ago and it’s changed my life. I want to ride my bike all the time, and am counting down the days to spring. During the warmer months I run all the errands I possibly can with my bike instead of driving, and ride for pleasure often, going on multi hour bike rides. It’s just such a blissful feeling, and as I’ve gotten more fit I’ve been able to turn down the bike assist and built a lot of leg muscles.

Sometimes the root problem is that your neurochemistry is FUBAR and no amount of counseling with overcome a biological cause.

Frankly, I see this as similar to telling diabetics that they should use just enough insulin to get them to learn to stop being diabetic. That’s possible for a few type 2 diabetics who could make lifestyle changes that got them back into good ranges. It’s completely useless for type 1 diabetics, or type 2 who can no longer go back.

I’m neither diabetic nor depressed. I don’t have a dog in this hunt. I’m just always astonished at “have you tried not being depressed?” Some people can “snap out of it”. Many times that number of people cannot.
by Fnoord | 2026-01-29 16:35:50+00:00
Well, that depends on your use-cases. Your profession, hobby, etc.

If you perform pentests or red teaming, a mobile device with CLI access is very useful (whether a smartphone is suffice I leave up to the reader). If you are using the device non-mobile, you could attach an external screen and keyboard to it (and perhaps pointer device, I like the Apple Magic Trackpad, even on Linux it works well these days). That way, you could for example write your pentest report on the machine while not fscking up your eyes. Also remember: if you got WLAN or 5G you can get access to more horsepower. It is not as if you were going to run hashcat on these devices locally. You can also run SSHd (and even remote desktop, I guess) on the machine and admin it like that from a fully blown computer. You could also use it with SDR, or for example for reverse engineering (which you could do in a VM as well, if you prefer).

Personally, I think this device would be pretty cool for a kid to learn Linux on (better than the Hackberry Pi CM5 which I got). The UI is neat, there's a CLI, and they can game on as well as explore on it. Pretty good deal a ~250 EUR machine to learn Linux on, as well as game. Remember: if it is ARM, it can run all the Android apps via Waydroid. No emulation or x86-64 Android versions necessary. I see it as a successor to Clockwork Pi GameShell [1] in that regard, as even the 2 GB RAM version is more powerful. That device had only 1 GB RAM, and:

> Introducing new Clockwork OS, based on Debian 9 ARMhf and Linux mainline Kernel 4.1x. You can run PICO 8, LOVE2D, PyGame, Phaser.io, Libretro, and many other game engines smoothly.

There's the Clockwork uConsole [2] as well, and you can put a RPi CM 3 or 4 in it. The A-04 variant specifically seems akin to the Mecha Comet i.MX 8 variant.

> A-04 ARM64-bit Quad-core Cortex-A53 1.8GHZ 4 Mali-T720 2GB DDR3

The RISC-V variant only has 1 GB RAM, the other variants got 4 GB DDR4.

Both the uConsole and the Mecha Comet are candybar format. Compared to Clockwork Pi's Devterm and GPD Pocket series which are clamshell. The Mecha Comet however allows you to easily swap the keyboard with a gamepad. The Clockwork devices don't allow this; they're tailored for either keyboard candybar, keyboard clamshell, or gamepad (candybar).

It's more performant than other similar libraries such as the Owner and cfg4j which no longer seems to be actively developed at this point and others such as Spring's Environment and MicroProfile config implementations

See benchmarks here: https://github.com/joel-jeremy/java-config-library-benchmark...

Aside from the performance, the strongest reason to use this config library I would say is how it makes testing easier and how easy it is to integrate with your dependency injection frameworks of choise.
by pigon1002 | 2026-01-29 16:36:13+00:00
I feel the same way. AI coding skills seem to sit somewhere between intermediate and advanced. Unless you’re working in a space where you’ve thought very deeply and developed your own solutions—those “gotcha, you didn’t know this” kinds of problems—it doesn’t really feel like AI falls short.

So far, I’ve been reading through almost 100% of the code AI writes because of the traps and edge cases it can introduce. But now, it feels less like “AI code is full of pitfalls” and more like we need to focus on how to use AI properly.

Do you want the control systems of the subway to get modified by a malicious actor? What about damn releases? Heat pumps in apartment buildings? Robotaxis? Payroll systems? Banks?

Amutability is a huge security feature, with tons of real world applications for good.

The fact that mega corps can abuse consumers is a separate issue. We should solve that with regulation. Don't forsake all the good that this tech can do just because Asus or Google want to infringe on your software freedoms. Frankly, these mega corps are going to infringe on your rights regardlessly, whether or not Amutable exists as a business.

Don't throw the baby out with the bath water.

I've ridden the Wolverine, it isn't half bad.

I 100% agree trains might be underfunded in the US. The LA to NY flight will stay preferred to a hypothetical high speed train due to time. It is unlikely ever to be less than 10 hours.

For train rides under 4 hours, and if you can get trains running smoothly (less stops), the time spent on the train and the overall integration of trains is a lot better as a mode of transportation.

Along that line I would rather all the parts be identical for all years of a make/model of a vehicle. Simplify EV's to be just slightly more complex than a golf cart and this should be doable. Or for that matter make all parts for all cars identical and the only difference could be the comfy part of the interior. I'm just trying to make Edward Bernays roll over in his grave so that his uncle Sigmund Freud can giggle in his grave.

If we can not support a car for 20+ years then the car must not cost more than $1599.99 and that price must not increase until the year 2150. What should set cars apart now should be how fast they can fly.

This strategy seems inspired by TikTok's approach for retaining new uploaders.

TikTok used to give new uploaders a visibility boost (i.e., an inflated number of likes and comments) on their first couple of uploads, to get them hooked on the the service.

In Anthropic/Claude's case, the strategy is (allegedly) to give new users access to the premium models on sign-up, and then increasingly cut the product with output from cheaper models.

> Does suffering matter if death follows eventually? The dead cares about nothing, because it remembers nothing

Yes it matters. Causing suffering to a consciousness that can experience pain is inhumane.

Now, reasonable people can disagree how far to extend our circle of empathy. Some would exclude animals or even other humans (eg criminals or someone of a different ethnicity), while other people would go so far as to include ants, plants, or rocks. I think both extremes are wrong.

Perhaps more poignantly to you question, what if you ask yourself:

- does your answer change considering humans are also animals?

- regardless of target, what does it say to the character of a person who chooses to be cruel when they don’t have to

Of course, your suggestion (better service for users who know how to speak Proper English) would be the cherry on top of this strategy.

From what I've seen on HackerNews, Anthropic is all-in on social media manipulation and social engineering, so I suspect that your assumption holds water.

Immediately hitting the brakes when a child suddenly appears in front of you, instead of waiting 500ms like a human, and thereby hitting the child at a speed of 6 instead of 14 is a success.

Lemonade doesn't support your claim that FSD is a safer driver than you are. It just says that, most charitably, they believe FSD and a human operator are safer than just a human operator (The co-founder said exactly this to Reuters [0]). Further, the program has only been around for a week and their marketing copy specifically cites "Tesla's data" as the source for the 50% reduction rather than any sort of independent analysis.

Show HN: Measuring runtime strain in autonomous AI systems
by PapaShack45 | 2026-01-29 16:39:07+00:00
This is a small runtime safety primitive I’ve been working on.

It computes a bounded “GV” signal from live agent behavior (token velocity, tool calls, errors, recursion, repetition) and emits:
green / yellow / red → continue / slow / halt.

The goal is runtime survivability rather than training-time alignment.
No model introspection, deterministic scoring, and designed to be embedded directly into agent loops.

There’s a short demo script in the repo that simulates an agent going unstable.
Feedback welcome.
