dominicdoty commented on Ask HN: Where are the good Markdown to PDF tools (that meet these requirements)?    · Posted by u/SamCoding

Whoa this is weird timing - just this weekend I did a little exploration of using Svelte to create documents and eventually PDFs.

Its really just a proof of concept at this point, but it might be of interest to you (and others).

Code: https://github.com/dominicdoty/sveltedoc

Rendered: https://sveltedoc.pages.dev/

Writeup: https://www.dominicdoty.com/2025/03/02/sveltedoc/

TLDR - I've been using Asciidoc a lot at work recently and was dissatisfied with it. This was an attempt at using Svelte to generate a document as a webpage that formats well when printed (or printed to PDF). All the power of HTML+CSS+JS when you want it, but the ease of use to just write markdown when you don't.

Watched several times, amazing stuff.

Had flashbacks to playing Jupiter Landing on the C64!

Edit: SpaceX should create a simple 'catch' the rocket game. Play in browser style. Just for kicks and marketing.

Shameless plug for my own project with a similar bent - write your own lunar lander autopilot in browser

>"The Architecture Astronauts will say things like: “Can you imagine a program like Napster where you can download anything, not just songs?”"

Yes, and that is how things like VPNs, Tor, BitTorrent (but more broadly, P2P file sharing/downloading), Bitcoin (but more broadly, cryptocurrency/blockchain) and (more recently) Decentralized (aka "anti Big Tech censorship") Video/Content Sharing -- were all invented...

dominicdoty · a year ago
I think the counter to this would be that if you focused on the "listen to a song I want right away" problem - you would have invented Spotify. From a business perspective inventing Spotify is probably better than inventing bittorrent. Elegant solutions are lovely, but often miss the problem people wanted to solve. Sometimes a useful product is built on top of an elegant solution e.g. WireGuard vs Tailscale. Seems similar to academic research vs engineering. Both useful, different goals/outcomes.

Power assist lets you turn a wheel with one finger at any ratio the manufacturer chooses... at most you'll get a lag in the assist but not in the mechanical movement (and I'd be amazed if that is perceptible with electric assist let alone hydraulic)

There isn't really any excuse for this.

It's hardly a performance car so perhaps it's not a big issue, but it really should not the there and should be fixed.

Because the steering ratio is variable, the movement shown in the video is about the equivalent of two full turns of a normal steering wheel. I tend to agree with the parent, it'd be hard for a human to equal this performance.

I don't think I've seen anyone else suggest it- the Comma Body might be an interesting platform for this. No manipulator unfortunately but a decent place to start.

the only difference between before is that we are much much better at handling nature and the climate. We are so good at it that we reduced death from climate related catastrophees by 95% the last 100 years.

Unfortunately the youth is being lied and manipulated thinking the opposite. Its become a religion worshipping nature and politicians and the media is our days priesthood, promising salvation if we repent.

The most dangerous thing humanity can do is to not believe in the future. If you dont believe in tomorrow you wont invest into it. Its the principles of a death-cult.

It is so sad to see the youth wasting their years on pessimism when life is mostly positive even if you are not rich.

And now we see the new contender based on the same defaist attitude in the AI doomers using same speculative frameworks to claim the end of the world without a single thread of evidence

The "95% reduction in the last 100 years" feels like a misguided argument since our improved abilities to handle weather events will not hold if the weather patterns we've gotten so good at handling, change. If you exceed design conditions, your 95% reduction can quickly turn into a Texas blackout.

I agree that optimism is critical to keep moving forward. However I do disagree with your implication that young people believe that we cannot handle nature and the climate. The view I (anecdotally) encounter most is not the belief that we are incapable of handling it, but that we will refuse to handle it till it's too late.

Couldn't cloudflare show a page to the next handful of http requests from an IP informing the user that "something on your network is participating in DDoS attacks".

All the big providers could do this, just inject a little turnstile like page in front of the next cloudflare site you visit.

I would love to know if there's a compromised device on my network, and I don't have any real monitoring set up to detect it.

It's not a full solution, but at least informing users there is a problem is a good start.

dominicdoty commented on Ask HN: What are some hobby tech projects for a tech-savvy teenager?    · Posted by u/ParallelThread

If they're interested in software and hardware, robotics is a fun place to start.

Line following, object avoidance, maze solving, all sorts of cool options.

A relatively cheap option would be the micro:bit [1] and a chassis [2]. The micro:bit can run CircuitPython [3] which is an simplified version of Python that can run on embedded systems.

This setup offers lots of room for growth from graphical programming, to circuitpython, and then on to C programming.

This is very cool, I like the increasing complexity levels.

I actually made a similar thing based on writing your own autopilot for a Lunar Lander [1]. It's hard to make the difficulty increase linearly though. I like the use of different scenarios in this one.

this is what life on earth does. it's not some kind of wacky googly eyes rube goldberg machine, it's what plants and animals have been doing for hundreds of millions of years. carbon capture's job is to refine and accelerate the plant side of the equation
dominicdoty · 2 years ago
From an engineering perspective life is an incredibly sensitive rube goldberg machine.

We have yet to find another world that has the right combination of googly eyes and string and tape to sustain relatively stable complex life. We struggle to understand the far reaching effects that even simple changes have on our planets systems and ecosystems. We have evidence of the system throwing itself so far out of whack that huge portions of life have died off.
