Hi Hacker news,

I’m Peace, co-founder of rivva.

Like many ambitious people, I built a reputation for getting a lot done. Over time, that ability to push through became both my strength and my weakness. By 29, I had burned out twice.

That forced me to rethink productivity. I started studying how cognitive energy works and how much it is shaped by sleep, context, and timing.

I reached one clear conclusion: productivity is not about squeezing more out of time; it is about managing energy. Focus, creativity, and judgement rise and fall through the day, and our best work happens when effort matches that rhythm.

That is why we built rivva.

rivva brings your email, tasks, and calendar into one system, then schedules work based on your energy patterns and real availability. The aim is simple: help you get important work done without overload.

What rivva does:

- Task management: Capture, organise, and schedule tasks in one place.

- Inbox: Extracts tasks from email, including meeting notes, Jira issues, and Notion comments.

- Energy insights: Connect your wearable and see when you are naturally sharpest.

- AI scheduling: Plans work around availability and energy patterns.

- Nia (AI chat): Create tasks, plan your week, set up meetings, or ask for guidance.

- Planner: Multi-calendar view with time-blocking and planning.

We built rivva for founders, executives, and high-output professionals who already work hard and want a system that respects how the mind actually works.

I would genuinely love to hear what you think. Try it out and tell us what feels useful, confusing, or missing.

This is generally true, volume and low cost situations exacerbate it, but it’s not limited to Chinese manufacturing. You see it everywhere. As a completely unrelated example: home remodeling. The guy I contracted did wonderful work and charged a completely fair price, but there were many parts that I hand waved at “he knows best” “he’ll pick the most sensible approach that matches the quality of the rest of project”. Wrong. Cheapest, fastest thing, isn’t materials on hand if possible every time. The economics are obvious and it doesn’t matter to him insofar as I don’t notice or acquiesce. Why should it be any different for low cost mass manufacturing?
by tfehring | 2026-02-04 14:54:34+00:00
I don’t think that statement was missing the point. As you point out, what matters is the total cost of ownership of the system. The cost of launching mass into space today isn’t the only reason terrestrial data centers are more cost effective today, but it’s the main one. If you make it cheap enough to send giant solar arrays and radiators to space, the other costs of operating in space may start to look like a small price to pay to eliminate the need for inputs like land and batteries.

It seems unfortunate that enhanced protection against physically attached devices requires enabling a mode that is much broader, and sounds like it has a noticeable impact on device functionality.

I never attach my iPhone to anything that's not a power source. I would totally enable an "enhanced protection for external accessories" mode. But I'm not going to enable a general "Lockdown mode" that Apple tells me means my "device won’t function like it typically does"
Show HN: ClawSimple – One-click OpenClaw assistant(s) you can deploy in minutes
by jinzheio | 2026-02-04 14:54:40+00:00
Hi HN, I’ve been following the OpenClaw project and noticed frictions for non-expert users: most discussions and docs are too nerdy... Installing OpenClaw costs lots of brain cells. Uninstalling costs even more! Besides, security/privacy risks exist for non-technical users.

So I built ClawSimple, a tool that make deploy and run your own OpenClaw-based assistant easier.

With ClawSimple you can:

- Spin up one or multiple OpenClaw robots in a few minutes;

- Focus on using the assistant instead of wrestling with deployment details.

For people who don’t want to pay for a managed service, I also provide a free, self-hosted option: the same deployment logic packaged as a one-line install script that you can run on your own cloud server.

Because this is handling personal conversations, I designed the server-side with a zero-access approach: deployment uses one-time credentials so that I, as the developer of the site, cannot access your content or conversations. -- I’d especially love feedback on this part from people who care about security and privacy.

If you’re interested in OpenClaw but have been put off by the complexity of installation and cleanup, I’d be grateful if you could try this and tell me:

- Is the setup flow actually simple enough?

- Does the “few minutes to first conversation” promise hold for you?

- What would make you trust (or distrust) the zero-access design?

Happy to answer any questions about the implementation details or tradeoffs in the thread.

I soft-launched this on ProductHunt and got some early users, but I'm interesting in feedback from HN on the 'deployment model' and security assumptions.

That is again a claim with no backing that can be applied to anything without actual data to back it up.

For example. I can just as equally state with the same data to back me up (ie: none as it stands right now) that you are a US government plant posting propaganda to encourage people to not use safer technologies and as a result make their data easier to spy on.
by theyregr8 | 2026-02-04 14:54:52+00:00
Yeah you can't predict anything with 100% certainty either

By repeating propaganda at you though desperate financiers can hack your brains innate prediction loop to convince you you're knocking on the door of infamy.

Look, I get you. You're trying to fill the hole created when father never came back with cigarettes. Mom always blamed you for his leaving. But little Warboy screaming "Witness me make line go up !" everyone else is a self selecting meat suit too working unintentionally (simply distracted by their own lives needs they never encounter your pitch) and in some instances intentionally (fomenting economic and political instability) against you to support themselves.

FWIW, when a problem truly is weird, AI & vibe coding tends to not be able to solve it. Maybe you can use AI to help you spend more time working on the weird problems.

When I play sudoku with an app, I like to turn on auto-fill numbers, and auto-erase numbers, and highlighting of the current number. This is so that I can go directly to the crux of the puzzle and work on that. It helps me practice working on the hard part without having to slog through the stuff I know how to do, and generally speaking it helps me do harder puzzles than I was doing before. BTW, I’ve only found one good app so far that does this really well.

With AI it’s easier to see there are a lot of problems that I don’t know how to solve, but others do. The question is whether it’s wasteful to spend time independently solving that problem. Personally I think it’s good for me to do it, and bad for my employer (at least in the short term). But I can completely understand the desire for higher-ups to get rid of 90% of wheel re-invention, and I do think many programmers spend a lot of time doing exactly that; independently solving problems that have already been solved.

Optical switches are great but they suffer from one problem that will annoy anyone that spent a ton of money on one: They don't last forever.

The reason is that the optical components are all plastic and that plastic degrades (yellows) over time due to exposure to UV light (which is all around us). They should last about 10 years in a normal office environment but I've heard reports that they're really only lasting about ~5 years.

Admittedly, five to ten years is probably fine. Just the gunk buildup in a normal keyboard is enough that most people would rather just buy a new keyboard than deal with cleaning it out. Even if the switches are hot-swappable! It really is a tedious thing that requires a lot of time and special tools (to do it right). Some keyboards and switches can only be hot-swapped a few times before they start to become wobbly/loose anyway.

I designed my Void Switches (https://github.com/riskable/void_switch) because I was sick of replacing keyboards so often (my fingers are like salt-water-drenched hammers, apparently). I also wanted a keyboard that was super easy to clean! Check it out:

https://imgur.com/pqGf0se

Every few weeks I take the top of my keyboard off and clean it out in sink with soap and water (and a scrub brush made for dishes). Been typing on this AHEK-95 for just over three years now so I've probably washed it at least 50 times and it's still working great!

NOTE: This is NOT patented technology! Logitech, Wooting, and all other keyboard manufacturers: WTF are you even doing‽ Copy my design already! I'll even help you do it! Make a keyboard that lets end users 3D print replacement switches/parts and you'll OWN THE MARKET (until others hop on board). What are you waiting for‽

This makes a lot of sense to me.

I've heard Codex CLI called a scalpel, and this resonates. You wouldn't use a scalpel for a major carving project.

To come back to my earlier comment, though, my main approach makes sense in this context. I let Opus do the abstract thinking, and then OpenAI's models handle the fine details.

On a side note, I've also spent a fair amount of time messing around around in Codex CLI as I have a Pro subscription. It rapidly becomes apparent that it does exactly what you tell it even if an obvious improvement is trivial. Opus is on the other end of the spectrum here. you have to be fairly explicit with Opus intructing it to not add spurious improvements.

I think you have to get in early to understand the opportunities and limitations.

I feel lucky to have experienced early Facebook and Twitter. My friends and I figured out how to avoid stupidity when the stakes were low. Oversharing, getting "hacked", recognizing engagement-bait. And we saw the potential back when the goal was social networking, not making money. Our parents were late. Lambs for the slaughter by the time the technology got so popular and the algorithms got so good and users were conditioned to accept all the ads and privacy invasiveness as table stakes.

I think AI is similar. Lower the stakes, then make mistakes faster than everyone else so you learn quickly.

As a long time marijuana user, these pro weed articles always crack me up. Sure it has some limited legitimate medical usages for pain or other applications. Vast majority of users are just addicts in denial, myself included for the longest time. Anthropologists in the future will be studying the effects of drastically increased marijuana consumption on society for decades in the future. I do wonder when the general populace will wake up to the propaganda, for example, how it’s clearly a gateway drug and clearly addictive on some level.
by tash_2s | 2026-02-04 14:56:16+00:00
Totally. I think this kind of thing sits right on that line: it can help someone (hands-free guidance, training, accessibility, staying in flow), and it can also slide into a pretty dystopian "score the worker" surveillance HUD. My intent here is the former: personal "real-world speedrun" / practice tooling, not a manager dashboard or productivity policing.
by danparsonson | 2026-02-04 14:56:31+00:00
You're very close to following that line of enquiry to its logical conclusion, which is that our nationalities tell us little of any real value except what our home culture was like where and when we grew up. Personally I've come to regard identifying as any nationality as silly except for legal purposes.

We're humans, and humans have always and always mixed between cultural groups, except in rare instances of total isolation; such people are not 'pure' anything, but they would likely be inbred. There is no 'pure' genetic strain of any race or indeed any organism. Whatever divisions there are between us are extremely blurry and constantly changing.

> I think just as hard, I type less. I specify precisely and I review.

Even if you "think just as hard" the act of physically writing things down is known to improve recall, so you're skipping a crucial step in understanding.

And when I review code, it's a different process than writing code.

These tradeoffs may be worth it, because we can ask the tools to analyze things for us just as easily as we can ask them to create things for us, but your own knowledge and understanding of the system is absolutely being degraded when working this way.

I recently needed to extract a sites content + track any new content.

I didn’t like the current tools, so I built meter. It syncs a website and fires webhooks whenever content changes.

To start, you just need to plug a site URL in. It will find any APIs or fallback to HTML if needed for the data.

Site here: https://meter.sh

Capitalism and socialism is a false ideological dichotomy. Mr. Beat has a good video on this. We live in a mixed economy.

Not to fall into the "communism is when free stuff" trope, but...

Most people like public schools, public roads, public transit, public parks, and public libraries.

The benefits of public goods are well known. This is the whole field of public finance economics.

Market failures are also well-known. Negative externalities, moral hazard, adverse selection etc. Hence carbon taxes, congestion charges, and universal healthcare.

In other words, sometimes free trade capitalism works, other times it doesn't, and it's not a mystery when. Marx's whole spiel about contradictions is wrong and largely throws the baby out with the bath water, so to speak.

I think they just meant to point out the petition was already available in several languages and tsak was just using one such English link, not to imply that using the main German link also solves mschild's notes.

I.e. it's one thing for a petition to not be on an official government platform/process but it's a completely different type of claim to say it's not even in the country's official language when it, of course, is.
by mcny | 2026-02-04 14:57:54+00:00
But none of those are usable, right? It will take decades of work at least to get a commercial grade mining operation going and even then the iron, titanium, aluminum would need to be fashioned...

Ah, I see the idea now. It is to get people to talk about robotics and how robots will be able to do all this on the moon or wherever.

Instantly pumps Tesla stock here now on earth!

Wow, 2.5% failure rates for customer CPUs?

I just... I dunno, I just mentally binned CPUs (as a solid state object, and one of the highest value add components to a system) to have failure rates in the ~1% range.

I know the effort it takes to get asymptotically closer to 0% failure rate, and so this is more of a misread (on my part) on what the market tolerates and the vendor's pricing/value strategy.

Cool!

It's definitely not a major threat, but many/most finance people are clueless about what is and isn't possible with LLMs.

Again, unless Anthropic are taking on liability for their legal tools, this is not going to impact TR.

That being said, there probably is a potential company here that's gonna be built soon/is currently being built, but it definitely won't just be a wrapper around Claude as the recall will be way too low for these systems unaided.

> The people that started in 3d printing when they had to assemble the whole machine by hand are now sad to see their hobby replaced by something too easy, it feels like cheating.

I have a 10 year old kit-built prusa I3 sitting next to me. Its brother is in the basement next to a kossel. It's been years since they have seen action, there is a litany of small bits of work they need.

I unboxed an A1 Mini and it's been like an epiphany. I've been printing almost nonstop. It's so much FUN. I just send from my phone and it just works. Everything has been nearly flawless until last night where half a batch of mini utility knife frames started to spaghetti, probably my fault for not fully cleaning the build plate in a bit.

Beats the hell out of glue stick or blue tape, fussing with slicer params, babysitting the first layers, etc etc. Fuck that, gimme the cheat.

Some background info on lockdown mode for those like me who didn't know:

Lockdown Mode is an optional, extreme protection that’s designed for the very few individuals who, because of who they are or what they do, might be personally targeted by some of the most sophisticated digital threats. Most people are never targeted by attacks of this nature.

Yeah; in Windows 3.1, Ctrl+Alt+Del took you to a blue screen that allowed you to kill an unresponsive task (but didn't display a list of tasks; the Task List was launched with Ctrl+Esc), or told you there was no such task to kill if there wasn't.

Before Windows 3.1 it just rebooted the machine as you described.

Launching Task Manager was the 95 to XP behaviour, but NT behaved differently -- even Windows NT 4.0 (developed alongside Windows 95) took you to the security screen with Ctrl+Alt+Del (something that would later be ported to Vista), where launching Task Manager was one of its options. These OSes weren't used residentially though, until Windows 2000 attempted to merge their lineages and Windows XP finally cemented the deal.

You missed the point.

Nobody describes a satellite by specifying the amount of heat that it produces, but by the amount of electrical energy that it consumes.

In a communication satellite, a large fraction of the consumed electrical energy goes into the radio transmitter. Radio transmitters are very efficient and most of the consumed power is emitted as radio waves and only a very small part is converted into heat, which must be handled by the cooling system.

So in any communication satellite, a significant fraction of the consumed energy does not become heat.

My impression was that Europe had a lot of old money. A lot of traditional and family banks that were only willing to risk it on "a sure thing." The startups I did work at were the founders did a stint in SV after being recruited from Europe. Came back with the knowledge and culture of startups. Tried to replicate it there and ultimately couldn't climb out the bureaucracy.

The capital is locked up in traditional large multinationals. I've watched them launch one boondoggle after another.

Every time something like this happens I assume it is a covert marketing campaign.

If the government wants to get in they’re going to get in. They can also hold you in contempt until you do.

Don’t get me wrong, it’s a good thing that law enforcement cant easily access this on their own. Just feels like the government is working with Apple here to help move some phones.
by hypfer | 2026-02-04 15:01:51+00:00
This (I think) refers not to the people securing their devices against third parties but the vendors "securing" the devices against loss of profits.

Essentially, the question referenced here is that of ownership. Is it your device, or did you rent it from Apple/Samsung/etc.
If it is locked down so that you can't do anything you want with it, then you might not actually be its owner.

___

_Ideally_ you wouldn't need to trust Apple as a corp to do the right thing.
Of course, as this example shows, they seem to actually have done one right thing, but you do not know if they will always do.

That's why a lot of people believe that the idea of such tight vendor control is fundamentally flawed, even though in this specific instance it yielded positive results.

For completeness, No, I do not know either how this could be implemented differently.

> Yeah of course it's a craze, without scare quotes.

This is a simplistic opinion to hold. You'd be better complaining that some people enjoy things. Form factor is important, also tactile response and sound. Features like embedding USB hubs or touchpads are essentially a given in laptops. Not being forced to throw a keyboard to the trashbin just because a key failed.

Is this a craze?

Ask yourself this: why are there people paying good money for gaming keyboards? Or Apple's magic keyboard. Is it a craze?

Or are you just complaining that other people enjoy things?

Think about it.

> So, not saying that it’s easy or feasible, but saying that cooling then seems “just” as difficult as power, not insurmountably more difficult

This is with an ideal radiator and perfect pointing so it receives no incident light, so in practice you need a bigger one than this.

However, if you think launching a solar panel that is the size of 10 NYC city blocks is "manageable," then why not throw in a radiator that is about 15 city blocks in size?

It'll work in this area of the country (Connecticut, Massachusetts,) because this is a known scam and relators and attorneys know to keep an eye out for this.

The problem is that a 4x8 plywood sign will weather very fast in New England weather. You're better off following the article's suggestion of flagging the property with the court.

BTW: When these scams happen, you can sue for the irreplaceable value of trees removed, especially if you planned on keeping the lot wooded: https://law.justia.com/cases/massachusetts/court-of-appeals/...

Freedom of one starts where it confirms freedom of others.

Of course everybody is going to find a point when freedom of speech have to be limited. Otherwise, anyone can justify that cutting the head of their neighbour with a katana while dancing is part of an artistic performance, and absolute free speech is only possible if all artistic expression is given complete license. Those who pretend otherwise will have no ground to defend themselves on legal basis from being wiped out of existence by the very same logic.

Space is a vacuum and yet here we are on a rock floating in space warmed by the sun and the temperate is actually pretty comfortable. Indeed, without the greenhouse effect it would be positively chilly. An important part of a thermos is that you have to use high albedo materials in the vacuum chamber or else it would lose heat too quickly to radiation.

A satellite as a whole will come to thermal equilibrium with space at a fairly reasonable temperature, the problematic part is that the properties of electricity make it easy to concentrate a good part of the incoming energy in a small area where the GPU is. Heat is harder to move than electricity and getting that heat back out to the solar panels or radiators requires either heavy heat pipes or complex coolant pumps.
