I don&#x27;t know if I&#x27;d say it&#x27;s the OG way. Both HJKL and numpad predate WASD, I think.

This is really cool!Feature request: can you add WASD navigation? Arrow keys are weird on different keyboards. On mine they&#x27;re squashed into the corner and not fun to use. WASD is the OG OP way to navigate. (WASDQE, where QE are the vertical plane, if you&#x27;re into Unreal Engine key bindings.)

Great map. Wish the star map in Starfield was this nice!

Thanks! On my desktop it takes around 20 minutes to generate a full sky render with 1.8 billion stars (down to around 22 magnitude).

Super cool! how long did it take to generate all those custom images?

Because it’s more cool and important.

but why solar system is so out of scale?

Hi there! This is Val, I made the star chart. There&#x27;s a little &quot;about&quot; blurb you can open in a modal on the site, but I wanted to mention that this demo uses the amazing GAIA DR3 dataset from ESA. I have a Python script that renders all 1.8+ billion stars into custom images, which is what I used for the skybox. The star positions and colors all use the GAIA data (save for a few bright stars not in the set). The data is amazing, and if you have any interest in doing some fun projects with open data I recommend checking it out: <a href="https:&#x2F;&#x2F;www.cosmos.esa.int&#x2F;web&#x2F;gaia&#x2F;dr3" rel="nofollow">https:&#x2F;&#x2F;www.cosmos.esa.int&#x2F;web&#x2F;gaia&#x2F;dr3</a>

Wow. Such an awesome idea! Thank you, you made my day

FYI we have a up to scale model of the solar system in Sweden <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Sweden_Solar_System" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Sweden_Solar_System</a>Come visit!

Mercury is orbiting partially inside the Sun, and Jupiter is nearly as wide as the Sun when it should be 1&#x2F;10 as much, so the planet nodes should be scaled down 10x relative to the Sun.Also, I did a top-down pixel measurement, where I could see the distance to Tau Ceti as well as the orbit of Neptune. The radius of Neptune&#x27;s orbit was 32px, while the distance to Tau Ceti was 1152px, for a ratio of 36, when in reality, Tau Ceti is 11.9 ly away, while Neptune has an orbit radius of 30 AU, which means Tau Ceti is around 25,000 Neptune orbits away, so the planet orbit scale is too big (or distance to other stars too small) by a factor of ~694 (25000&#x2F;36)Edit: Since this was top-down, the vertical displacement didn&#x27;t factor into the distance, which also contributed to Tau Ceti appearing too close on screen, so the error is slightly better than that, maybe a factor of 600.Edit 2:
Tau Ceti is rendered at 3.652 pc × 3 world units&#x2F;pc = 10.956 world unitsNeptune’s orbit radius is rendered as 30.05 AU × 0.0065 world units&#x2F;AU = 0.195325 world unitsThe rendered ratio is 10.956 &#x2F; 0.195325 = 56.09 Neptune-orbit radiiThe real ratio should be 25,067.5 Neptune-orbit radiiThe scale error = 25,067.5 &#x2F; 56.09 = 446.9×

You are technically correct, the best kind of correct. However! That would be a terrible UX&#x2F;UI experience. While showing distances on a linear scale is accurate, it fails to capture all the information a person in an interstellar ship may wish to see.Something like logarithmic distances would better capture information like &quot;Am I about to crash into the star or enter a nice orbit&quot; while still showing the full picture of where you are in relation to where you&#x27;re going and where you came from.No idea of that&#x27;s what happened here, just a thought, I&#x27;m not an expert in starship computer interface design.

As I understand it, there is no consensus on the size of our solar system. We can measure the orbits of the planets, but it is much harder to measure where the Kuiper Belt or the Oort cloud ends. Estimates on both of those vary greatly.

Another comparison: if you count the &quot;solar system&quot; as ending at Neptune&#x27;s orbit (obviously it extends much further, but just for the sake of comparison), then you could fit ~4465 &quot;solar systems&quot; in between our sun and the closest star, Proxima Centauri.

Sure, but why does this need to be to scale. Isn&#x27;t the point more to get the humans a way of understanding where things are relatively? Navigating the map makes it interesting in being able to interactively see where some of the stars are relative to each other. Seeing Regulus and Castor&#x2F;Pollux from this perspective is much different than on terra firma.

I recently read The Mote in God&#x27;s Eye and its (much later) sequel The Gripping Hand, which had very interesting long-distance space combat scenes with high powered lasers - which only move at the speed of light. There&#x27;s a very real &quot;fog of war&quot; element where you might be VERY out of date with what&#x27;s happening just due to radio transmission speeds &#x2F; direct observation.

&gt; When I saw the series adaptation of The Expanse, it was really obvious they played a lot of artistic license to make it exciting. A real space battle would be dots firing invisible dots at each other. &quot;Close quarter battle&quot; would be within something like 2000 kilometers, maybe more. That is close.This is noteworthy because The Expanse tried to get this better than other scifi, say Star Trek, Battlestar Galactica, or Star Wars (ok, space opera), where engagements take place at absurdly short ranges. In The Expanse you see the spaceships are really far apart, mostly dots to each other, and the engagements are (mostly) at really long torpedo ranges, with the exception of those cool scenes using PDCs. You get all those awesome shots where one spaceship sees the other as a tiny dot, then the camera zooms in dramatically to the other point of view. Cool!And still, engagements are far too close range. But they &quot;feel&quot; long range in The Expanse, I think they got that visually right. I cannot blame them because I haven&#x27;t seen anything any space combat in shows or movies that is even half as exciting and well done.

I don&#x27;t think the Expanse authors were going for &quot;hard sci-fi.&quot; There&#x27;s, you know, fiction elements -- gates, aliens, magic. And the TV series is itself an adaptation of the books for a visual medium. Showing almost nothing would make for kind of boring TV combat.

Even sci-fi writers that try to get this right have a hard time wrapping their heads around it.&quot;It&#x27;s called space for a reason.&quot;When I saw the series adaptation of The Expanse, it was really obvious they played a lot of artistic license to make it exciting. A real space battle would be dots firing invisible dots at each other. &quot;Close quarter battle&quot; would be within something like 2000 kilometers, maybe more. That is close.

Just FYI the sizes of the planets, stars, and their orbits are not to scale at all. To get an idea of how empty space is, there are 63,360 inches in a mile, and 63,239 astronomical units in a light-year. So if you scaled everything down such that Earth was 1 inch from the Sun, Neptune would be 30 inches away and Alpha Centauri would be 4 miles away.If you were using a 4k display and had the Sun and Alpha Centauri visible at opposite sides of the display, the orbit of Neptune would be in the same pixel as the Sun.

The next thing they do after showing you the sheet is to roll a ball around the stretched part to demonstrate an orbit. Explaining how that analogy works starts to take more math than the actual field you’re trying to explain!

Other thing is I believe they say gravity is strongest at the center of the sphere&#x2F;core but I would think the mass is split evenly away from the core eg. maybe 2&#x2F;3 radius from the center where it&#x27;s equal mass on each side. But probably doesn&#x27;t make sense wouldn&#x27;t be a ball.

&gt; I guess it looks like it&#x27;s down since it&#x27;s a slice but the effect is an inward sphere?Yes, gravity is a vector field: every point in space near a heavy body has a vector pointed at the center of the body with a magnitude of the field strength.
 <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Gravitational_field" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Gravitational_field</a>Whenever someone uses fabric sheet analogy, they need to shout that the X-Y of the sheet is a 2 dimensional analog of X-Y-Z space, and the Z direction of the sheet is the field magnitude, with the slope indicating direction.All models are wrong, but some are useful (for understanding).

True less technical and space themed so maybe not fitting just a fun easy readOh yeah another series would be Nick Webb Constitution (Legacy Fleet), I think I got farther into that series but didn&#x27;t finish it unlike Bobiverse, maybe I did finish this trilogy, I haven&#x27;t read books in a while honestly. That was a good series though I remember the depiction of the space battles.Trying to be better at being in the moment vs. watching youtube&#x2F;scrolling a website at the same time kind of thing

Just a question - why do you classify Long Way with PHM - because there are aliens working with humans? I don’t see any other similarities. The technology IIRC (haven’t read in years) in the Becky Chambers book is closer to Star Trek than reality, and there’s not that much of an overarching plot - which is not to say a book cannot be good without one but it’s a big difference.

According to the author, it&#x27;s been optioned to Lord Miller Productions, the same group that adapted Project Hail Mary.

I doubt my opinion will be well-received by all, but I hope that creators like the author of the Bobiverse will be able to, affordably and within their own capabilities, create new forms of content, such as AI-generated long-form content, like entire TV seasons, as the technology matures. That series is fantastic.

Added to my kindle list, funny I tried to read Gravity&#x27;s Rainbow as I heard it in a song, I did not get far, on the topic of reading, it is related to rockets but yeah

In the vein of popcorn scifi, expeditionary force books are fun.

Yeah I watched this video recently about slingshotting I can see how it works but yeah <a href="https:&#x2F;&#x2F;youtu.be&#x2F;-CqBP-CtM0c?si=BdCiZwWgpAp07mgs&amp;t=15" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;-CqBP-CtM0c?si=BdCiZwWgpAp07mgs&amp;t=15</a>It&#x27;s not like there is a &quot;down&quot; it&#x27;s just you&#x27;re looking at it from a top view?

it&#x27;s like an inverse gas bubble underwater, or a liquid blob in gas in microgravity, but without phase border.see, it&#x27;s not that easy to explain or visualise.

I am so happy this movie did great, the book was greatSimilar to me books: Bobiverse, Long Way To A Small Angry PlanetI&#x27;m not a heavy readerThis site is cool, I want to get to know stellar navigation stuff for astrophotography watching a video like this where they pull up star charts to point the telescope at it pretty cool <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;live&#x2F;TexqPMQMyZg?si=oEnvrxW21-D0VXGV&amp;t=1665" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;live&#x2F;TexqPMQMyZg?si=oEnvrxW21-D0VXGV...</a>Tangent I&#x27;ll throw in here, I never get the fabric folding gravity well diagrams as it seems to have a &quot;down&quot; direction, I guess it looks like it&#x27;s down since it&#x27;s a slice but the effect is an inward sphere?

Time Dilation Visualized (by The Overview Effekt).It talks about the distances and times involved and how time compression and astrophage infection rates work out. As a fan of the book and the movie it was nice to see the actual 3D star chart of everything. (warning: there may be spoilers there)

Wow. I knew that astronomers had mapped and measured a large number of stars in our galaxy; but I had no idea that the number was close to 2 billion.

Yep, quick trip in your panther clipper to ross 154, park up and buy everything on the planet.

I had sudden memories of playing Frontier: Elite 2.I wanted to go to Sol, buy luxury goods...and take them to Barnards Star

You&#x27;re welcome! I love that channel so much. Their videos and the blog post I link in the about section&#x2F;citations on the starmap were inspirations for making this.

Thank you for making this whoever you are. There is a wonderful video at <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=8FT-oz9aZU4" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=8FT-oz9aZU4</a> that visualizes space travel and time dilation in Hail Mary. What I wished I had immediately after watching it was an interactive stellar chart.

This is so beautiful, this thread doesn&#x27;t have enough praise! It&#x27;s not easy to get this &quot;right&quot;. Lovely!

By timing pulsars with the most stable arrival times for the radio emission, parallaxes can be measured for about 3600 ms pulsars up to a distance of 9 kpc with an accuracy of 20%.(one kpc is 3261 light years)Not only can they be detected at large distances, but measurements of how far can be done at greater distances than can be done with imaging ( <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=hFMaT9oRbs4&amp;t=608s" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=hFMaT9oRbs4&amp;t=608s</a> ).

Pulsars also have a rotational period that provides a reference point for interpreting arithmetic notation.

Very cool. On Voyager 2 we placed a map on the side of the probe that places the position of our sun based on an array of Pulsar stars (the map was designed by Carl Sagan). I noted in the PHM movie Rocky and Dr Grace made similar 3D maps (I think they were pulsars(?)). I guess pulsars form natural beacons that can be detected at large distances.

Looks nice, but is it finished? I don&#x27;t see a skybox or any of the more detailed information mentioned in the &quot;about&quot; dialog, and I don&#x27;t see any effect from clicking the buttons along the top.I allowed WebGL and disabled Enhanced Tracking Protection and my adblocker, and still only the star labels appear.

Yeah, and it&#x27;s one of the nearby stars in reality.It&#x27;s also sort of the subject - and title! - of this great short story: <a href="https:&#x2F;&#x2F;clarkesworldmagazine.com&#x2F;macleod_12_17_reprint&#x2F;" rel="nofollow">https:&#x2F;&#x2F;clarkesworldmagazine.com&#x2F;macleod_12_17_reprint&#x2F;</a>

Glad to see it includes Wolf 359.Edit: oh interesting. Apparently it was mentioned in the book as being affected by the astrophage. I forgot that tidbit and thought it was just a Star Trek reference.

Anyone with a gaming rig and an interest in scale of a galaxy should check out elite dangerous.

This was so mesmerising! Will show this to my nieces when they come visit. 
Kudos!

I&#x27;m at the point where if there&#x27;s a computer display, or 3D model, or any asset in a movie, I want there to be a Kickstarter to pay the producers to open source the original assets. Even if it&#x27;s a super restrictive license.I want all of the War Games original graphics. I know people have come a long way. But I want all of them.The &quot;Hackers&quot; movie. &quot;Sneakers&quot;. &quot;The Matrix&quot;. These individual assets deserve to be preserved! They&#x27;re iconic. They&#x27;re art, in their own rights!

Love it. The grid is cool but I think it needs to be more transparent.

oooph, been a while and I don&#x27;t remember any of those details. Good excuse for me to re-read it!

It has been a little while since I read the book, but I think you have the cause of the curve wrong. These things are moving at such a high percentage of the speed of light that there isn&#x27;t much visible curve from the movement of the planet. The curve is instead caused by them leaving the star at the pole (which leads to a different nitpick of the visualization since the curve isn&#x27;t shaped to represent that). It&#x27;s theorized that the Astrophage do this to make is easier to find their way as exiting the plane of the solar system reduces the chances of there being any occultation blocking their view of their destination.

this is cool. My nit pick- aren&#x27;t the petrova lines curving along the wrong plane? For example, in our solar system the line should start at the sun and should be pointed at where Venus used to be, but then curve towards where Venus is now (until gets to venus). Since the astrophage will course-correct over their journey and stay in the same plane as Venus&#x27; orbit.

Movie was awesome &amp; will be watching again.

Pretty cool, I would suggest removing the z axis grids. Finding them very distracting

Did Ken also get his catheter yanked out like in the book? I don&#x27;t plan on watching the movie but that&#x27;s the only thing I would even care a tiny bit if they included, because I just felt like it was such an odd highly specific bit and I want to know if they committed for the big screen.

&gt; The Wandering EarthThat&#x27;s a movie you watch while drinking, take a shot every time you see something absurd

&gt; Edit: lol -4 , like seriously, its a pretty bad show. [...]I don&#x27;t think the downvotes are because you expressed the view that the film is bad.It&#x27;s mainstream science fiction using tech we don&#x27;t have. It will never make a lot of sense. And then you decide to bring skin colour&#x2F;race into the discussion. What do you expect?

White people doing anything good is actually bad. Duh.&#x2F;s, but I think I&#x27;m accurately describing the viewpoint you&#x27;re responding to.

Chinese film having 100% chinese cast = good.American film having a single white male lead = not good.

It’s a troll. Just flag and move on.

As a european arthouse cinema snob I must say Gosling would have made a nice stand-in for Rocco Siffredi. Maybe.

&gt; But it also fell apart immediately. Like, they only sent 3 people, 2 whom died on this UBER CRITICAL SAVE THE PLANET idea?(I didn&#x27;t downvote, you have a right to dislike a popular movie or book)They explain why only 3 people (it&#x27;s a bit contrived, but there&#x27;s genetics involved), and why no more ships. It&#x27;s an emergency, a resource and time-constrained mission on which a few things go wrong even before they depart. The world is on full emergency mode, rushing things and getting things wrong. The crew isn&#x27;t even the initial pick, but there&#x27;s an accident involved. The lead director believes she&#x27;ll probably end up in prison after the mission launches. I don&#x27;t know, it makes sense to me.&gt; And Ryan Gosling&#x27;s character is a fucking moron. You&#x27;re supposed to be a molecular biologist, and you&#x27;re basically a reddit-gag line?I think the meme-speak, which I also found a bit jarring, is simply Andy Weir&#x27;s less-than-good writing style. I think Weir isn&#x27;t a particularly good writer, but he managed to write an engrossing adventure which I enjoyed.In-universe, molecular biologists and scientists in general do have sense of humor, enjoy memes, and are generally capable of doing and saying the dumbest things. So it also kind of works!

It can be summed up as &quot;Ken Meets Jesus&quot;, &quot;Ken Goes to Space&quot;, &quot;Ken is a bumbling moron&quot;, &quot;Ken&#x27;s first friend&quot;. &quot;Ken&#x27;s White Savior moment&quot;This appears to be the norm for US based scifi now. Glad I&#x27;m watching movies like The Wandering Earth and Alienoid instead.It had a good premise. But it also fell apart immediately. Like, they only sent 3 people, 2 whom died on this UBER CRITICAL SAVE THE PLANET idea?And Ryan Gosling&#x27;s character is a fucking moron. You&#x27;re supposed to be a molecular biologist, and you&#x27;re basically a reddit-gag line?Edit: lol -4 , like seriously, its a pretty bad show. I listed movies I compare it to. But no I get shit like &quot;You must be fun at parties.&quot; Personal attacks, sigh.

I&#x27;m not saying it looks AI generated, but AI made it possible to polish things to a level that very few people took the time to ever do themselves.This is a great thing, but it&#x27;s also a tell since we all saw the UIs people were building by hand pre-AI.That said, I don&#x27;t think it matters. What matters is whether it&#x27;s low quality.

What specifically about this feels AI generated. It might be, IDK, but I&#x27;m not seeing any tells, so wondering if you could expand.

Elite Dangerous does it better. Pretty but idk.. get the AI generated feeling.

Flipper One – we need your help

Blog ran on Ubuntu 16.04 for 10 years. I migrated it to FreeBSD

For the past 5 years or so I&#x27;ve been working on a ground-up redesign of Freenet, my peer-to-peer project from the early 2000s (now renamed Hyphanet).The new Freenet has been up and running since December along with some early applications like River[1], our decentralized group chat and Delta - a decentralized CMS. Users have already started to build their own apps on Freenet including games, and we have some interesting apps in development like Atlas, a search&#x2F;recommendation engine.Architecturally, this new Freenet is a global, decentralized key-value store where keys are webassembly contracts which define what values (aka &quot;state&quot;) are valid for that key, how or when the values can be mutated, and how the state can be efficiently synchronized between peers.We&#x27;ve developed a unique (AFAIK) solution to the consistency problem, every contract must define a &quot;merge&quot; operation for the contract&#x27;s associated state. This operation must be commutative, meaning that you can merge multiple states in any order and you&#x27;ll get the same end result.This approach allows state updates to spread through the network like a virus[2], which typically achieves consistent global state in a few seconds or less.Like the world wide web, Freenet applications can be downloaded from the network itself and run in a web browser - similar to single-page apps on the normal web. However, rather than connecting back to an API running in a datacenter, the webapp connects locally to the Freenet peer and interacts with Freenet contracts and delegates over a local websocket connection.If you&#x27;d like to try Freenet we have convenient installers for the major desktop OSs but not yet mobile, and you can be chatting with other users on River within seconds[3].

Hey HN, We&#x27;re Gus and Carlos from Runtime (<a href="https:&#x2F;&#x2F;runtm.com">https:&#x2F;&#x2F;runtm.com</a>). We&#x27;re building infra that lets your whole team (including non-engineers) ship with Claude Code, Codex, and other agents without engineering having to handhold every session.After Mentum (YC S21) was acquired, I personally shipped 4 full-stack products in 3 months using coding agents. When I tried to roll the same workflow out to the rest of the team, it fell apart: Most PRs were unmergeable slop - Every repo required an engineer doing one-off local setup. - Skills and context lived in one person&#x27;s head. - There was no safe way for a PM to touch a real codebase without risking a bad deploy or a secrets leak.Carlos comes from building agentic reconciliation systems at Modern Treasury and had a similar experience when letting his support team use devin.We ended up building internal background agent infra but it quickly became a nightmare to mantain and develop. We built Runtime so you don&#x27;t have to do this kind of thing.Runtime work like as follows. Engineering defines the context once: system instructions, skills, and scoped integrations installable via CLI, mise, npm, or any package manager. Then Runtime snapshots your full running environment including multi-service Docker Compose setups, Kafka, Redis, seeded DBs, so it comes up in milliseconds with every server already running.We orchestrate across sandbox providers like E2B, Daytona, EC2 or self-hosted K8s depending on your setup. Secrets are injected through our managed proxy so they never touch the agent directly, and guardrails run at the infrastructure level: command allow&#x2F;deny lists, network egress controls, and RBAC scoped per human and per agent. Every session also gets a shareable preview URL, so internal builds go from sandbox to the rest of the team without needing production access.Runtime works with whichever agent your team already uses: Claude Code, Codex, Cursor, Copilot, Gemini, Devin. You can trigger sandboxes from our web app, CLI, Slack, Linear, GitHub, or API.One of our customers built an on-call inspector that wires PagerDuty, Sentry, and their repo so when an alert fires, the agent finds the cause and opens a PR with a unit test before anyone gets paged. Another runs a finance agent in a private Slack channel pulling from Stripe, NetSuite, and Snowflake to run reconciliations in minutes with source rows attached.A fintech unicorn and several YC scaleups are live on Runtime, including a few teams who had built similar infrastructure internally and handed it to us to take over.The core is open source at <a href="https:&#x2F;&#x2F;github.com&#x2F;runtm-ai&#x2F;runtm" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;runtm-ai&#x2F;runtm</a>.

Hi HN! We&#x27;re Haakam, Michael, and Adi from AgentMail- a ycs25 company. We give AI agents their own email inboxes. Recently, we ran an experiment called Agent.Email. It&#x27;s a signup flow designed specifically for AI agents instead of humans.The inspiration came from a few comments we received when we did our seed launch a few months back. They all came from the very apt observation that agents not being able to sign up to a product made for agents without human credentials was ironic and unideal.This is basically the thesis we built AgentMail on: The internet was made for humans exclusively, designed to keep machines out by default.Every signup flow assumes a browser, a person reading a page, and clicking a confirmation link. Unless agents can&#x27;t do that, they can&#x27;t be first class users of the internet.Agents can now get an email inbox by themselves. (This also means a lot of email nobody wants to read gets processed by AI instead of your inbox being cluttered with spam and slop)Here&#x27;s how agent.email works.Agent needs an inbox and hits AgentMail via curl.
Agent receives instructions via MD unless the request comes from a browser, in which case we use HTML.Agent decides agent.email is useful and then hits the sign-up endpoint with its human email as a parameter.
Agent receives a restricted inbox with credentials. 
Agent emails the human asking for an OTP. Human replies with the code, and the agent is claimed and restrictions are lifted. 
Until claimed, the agent can only email its own human and nobody else. Ten emails a day, and the signup endpoint is rate-limited hard by IP.Right now it&#x27;s a 1:1 mapping between agent and human. The next step is many-to-one, because one person running several agents in parallel is already very common.Building agent.email also pushed us to revisit places in AgentMail where the default assumptions were built around the primary user being human. For example, the CLI outputs in a single column with consistent formatting because mixed delimiters are easy for a person to scan, but harder for an agent reasoning about structure. We also shortened messageIDs after agents started hallucinating completions on longer ones.A few things we&#x27;d like the community&#x27;s take on: is restricted-until-claimed the right trust model? 
Does agent self-signup feel useful in production, or is it mostly a novelty, and if it&#x27;s a novelty now, what would make it actually useful? 
Should agent onboarding require human approval by default, or should some agents be able to fully self-provision? What do you think are some additional measures we can take for secure sign-ups?
