fsloth··on Sixty percent of US consumers say 'AI' in brand messaging is a turnoff
I guess they can say "Made in China, designed by Apple in California" in the packaging but at least they still take pride in the design. With AI it sounds you are disavowing also the authorship of the design.
fsloth··on The founder's playbook: Building an AI-native startup
"Founding cannot be a commodity. If it is, you have no moat or point, meaning you instantly collapse again, because you are an interchangeable commodity."

IMHO you still need to find the product and PMF

There are bunch of books startup world recommends which sort of all start from the principle of product, users, traction.

This is sort of scaffolding around that. It's not entirely insane to try to formalize this process - there already are books that do this (Bill Aulet, Disciplined entrepreneurship).

"nor does it make sense for society to have people founding businesses at a scale"

Maybe not at scale of moving lawns but I'm pretty sure the world is full of nichces that still lack specific software offering or where options of software offerings are limited.

This is like "Uber for logging" or "time reservation system for cat dentists" level of "take existing product category and apply to a domain you know".

So not every cat dentist needs to found a cat dentist time reservation app but I'm sure there are niches withing niches with business opportunities awaiting.

fsloth··on WASI 0.3.0 Released
This! The only way to get to a stable system at least with c/c++ source, where you can hunt bugs, is to have a fairly large unit test coverage. When something fails - add that as test case; run ctest - pray that this is discoverable with tests.

So wasm is a really strange compilation target for systems programming languages.

I mean there _are_ ways to debug it in a browser but they sort of suck.

fsloth··on Why AI hasn't replaced software engineers, and won't
"has already replaced several software engineers. "

I think this is incorrect, unless your friends employed software engineers, or would have employed software engineers.

fsloth··on I'm Eric Ries, author of "The Lean Startup" and new book "Incorruptible" – AMA
"I think most of us are happy to believe that most companies simply have bad leadership"

I don't believe this for a second.

I don't know if this makes me the minority or not though!

It trivializes forces influencing large public companies.

Yes - there can be good and bad leadership - and bad leadership is just bad.

But good leadership can be totally helpless in a public company.

Not recognizing this is a huge gap.

The other forces that incluence a company:

- Board

- Shareholders (via board)

- Banks. Lots of companies have loans. The banks generally have the companies by the balls and can dictate many things when things go south - either due to leaderhip or just prevailing market winds

As an example of shareholder/board direct and rapid influence: an activist purchases shares. Installs board member. Causes rapid change in one or more aspects of business structure or strategy to support _their_ portfolio strategy (of course aligned with interests of other shareholders).

etc.

fsloth··on Bricks and Minifigs Stole a Man's $200k Lego Collection
I wish it was so as well but

"When McKinsey Comes To Town" by Bogdanich and Forsythe

documents exactly standard tactics such as these in e.g. insurance.

fsloth··on Bricks and Minifigs Stole a Man's $200k Lego Collection
"the crazy part to me is how blatant the executives of bricks and minifigs are in saying go ahead and try to sue us, we’ll drag this out "

To my experience this is a common strategy in disputes when the corporate party has people who operate as uncivilized brutes. I think it's part of the McKinseyfication of companies - profits at all cost - and here's the playbook.

My personal experience is from private parking control. Rather than be professional about my reclamation, their first response was "only criminals dispute these and we win all the court cases".

So I think trying to be imposing and villanous to scare the other non-corporate party to back off is a common global corporate playbook in situations in matters where companies enter contractual complex space with individuals.

fsloth··on Uber’s COO says it’s getting harder to justify money spent on tokenmaxxing

Would love to know what things!

fsloth··on Read Programming as Theory Building
In my mind design and theory are inseparable. Design is the accumulation of many design decisions. Theory explains what influenced those decisions.

Design needs theory to be intentional. It can of course be accidental (”seems to work, I guess”) or intuitive (”i know in my guts this is right but cant explain it”).

While both can end up with functional systems, if you cant vocalize the design journey the system is not very maintainable in the industrial sense (hence - theory is the vocalization of the design and the forces that influenced it).

fsloth··on Specsmaxxing – On overcoming AI psychosis, and why I write specs in YAML
Agree!

Another point of view is that LLM:s perform to an extent on the same level as outsourcing does. This interface requires a bit more contract mass than doing everything within single team.

fsloth··on Show HN: AI CAD Harness
Having worked in CAD for over a decade previously, I think the users want a product surface, and the people paying for the engineers time want a reliable trainable solution that will exist exactly as it is today in five years. They are happy to pay for it in monthly installments.

This is a separate dimension to alternative high quality modeling solutions alone.

Now, some of the users especially are _proud_ of their product specific skill set. They don't _want_ to switch a package.

And - it's much easier to get professional engineers to use extensions to packages their engineering office already uses.

And this comes before any technical side-by-side feature comparison.

fsloth··on The West forgot how to make things, now it’s forgetting how to code
"McKinsey comes to town".

Basically same shaped taylorism-derived industrial management has imposed itself as the "default dogma" in private and public administration.

fsloth··on ChatGPT Images 2.0
Do note the images will be sterilized and safe.

"Hey give me a comic of how to create a rocket engine i can build at home"

Unlimited creativity will be shackled by safety.

Still pretty amazing.

fsloth··on A Tour of Oodi
Really nice building and space.

The article summarizes the functional parts so well. What is very hard to communicate is the feeling of space, especially in the top floor with the books. It's sort of unique, and recommend a visit anyone traveling nearby.

I worked at the company that developed the software used to design the construction of Oodi (Trimble/ Tekla Structures). It's so awesome to walk through a building you know the tool you helped to build, helped to build :D

fsloth··on France to ditch Windows for Linux to reduce reliance on US tech
> I'm not convinced that replacing one proprietary OS with another is the solution.

Consumer don't care if the OS is proprietary, as long as it works and there is a responsible party they can trust to serve them the offering.

fsloth··on Moving from WordPress to Jekyll (and static site generators in general)
This is super interesting! Thanks for sharing. I’m wondering myself how to put up a site with usual product stuff, blog and manual.

The blog is running already on hugo on full llm automation but I had though it would not work for documentation (this is for non-techies so want something more product-manual -like and less SDK-docs flavour) or landing page that well.

So this is you company’s site and it’s on Hugo? https://formationxyz.com/

fsloth··on Ask HN: What are you building that's not AI related?
https://www.adashape.com/ - a humanistic CAD for 3D printing. Early but has profile editor, extrusions, booleans, and imports STL, STEP, SVG and bunch of visual mesh formats.
fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
Yes - supporting full manufacturing intelligence is part of the larger vision (in practice quite far off).

I don't think there is need to unseat anyone. 3D modeling market is expanding and the intent is to serve people for who are not users of current market leading tools. There are tons of plausible UX paradigms that have not been explored. This is one such exploration :)

"like could you make it aware of the fdm limits and help me avoid them while im building "

That's part of the long term vision. First solve modeling, then solve manufacturing of the models reliably.

The modeling already follows this principle - you can't model things the rest of the operations can't support.

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
Yeah, a typed tree structure is definitely what we want here.

I guess you mean https://github.com/oxc-project ?

Are there benefits compared to using, say, protobuf?

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
Export of the parametric model would fit well with the user respecting philosophy underpinning the whole project.

While https://xkcd.com/927/ is something to be avoided there really isn’t an existing format I would be aware off that fits the bill.

I’ll add this to the roadmap.

But to do this right it really needs to be a properly specified schema, with conformance test suite and versioning.

I appreciate your use case, but for users coming out of context, parsing underspecified XML files would be more of a curse than blessing :)

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
Thanks for the input testing!

I agree supporting ”pointy” input modalities - pens and touchscreens is valuable.

I don’t think there will an android port in the near future but appreciate the sentiment.

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
Ah, ok, so do I understand correctly you would sort of like a visual preprocessor for programmatic model data?

And specifically ”whatever xml”, not, say STEP, or , openscad code, python code (via using cadquery) or anything like that?

Do you know your final output format?

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
I've been using as low end testing machine my Thinkpad T14 Gen2 i5. I think you have the same iGPU (Iris XE) but the resolution in the Thinkpad is 1920x1080 while I think you have 2880 x 1800 screen (guessing, please verify :) ) .

If you are inclined to continue testing dropping the resolution or making the window smaller _might_ help. Also it's expected the user has a SSD.

My other testing platforms are a desktop rig with 4k screen/ 3080 GPU and Windows Sandbox (the latter being super sluggish). I've not tested on igpu with WQHD+ resolution - will definetly add this to my test matrix in the future. But don't know if I can help you right now.

This is great feedback btw. for alpha version regardless to whatever conclusions you come on the applicability.

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
Theoretically, yes, but in practice a structured XML description of a parametric model is not useful in the general case without standardized format.

STEP XML would be probably the closest here.

To be realistic, I might wrap a CLI to AdaShape first, then the user could query the model and have their LLM backport the model tree to something like CadQuery :D

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
Nice references!

The output resolution as such can be made "arbitrarily" precise if the model geometry is authored within AdaShape. So the facets in your image would not result from the limitation of the generated mesh (https://www.cnccookbook.com/wp-content/uploads/2017/08/facet...).

There resolution is currently fixed to presets for usability (see p. 28 of the changelog for the tolerance values - https://github.com/AdaShape/adashape-open-testing/releases/d...). I did not have CAM/CNC expert to consult on the details so those may be out of whack (but I'm happy to adjust them or add a user configuration).

"if it's a good fit, maybe I can take the manual off your hands?"

Would redistribution under CC BY 4.0 suit you?

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
Thanks!

I will definitely keep plugging at this :)

(Nothing against Mac as such, let's see if I will have bandwidth for a port at some point).

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
This is really good feedback.

The data model supports solving dependencies like this on the data level.

TBH I don't know at the moment how to make something like this accessible but will definitely keep it in mind.

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
Much appreciate the feedback!

> As a person who has crashed and burned with every. single. traditional 3D CAD tool

I hear you, there are reasons for depth and complexity but not every program needs to be like that.

>if this is a good fit, will gladly pitch in using this for 3D.

I notice you are discussing specifically CAD/CAM for CNC routers. I don't know if this is applicable for your use case or not. Would be very interested to hear your opinion!

The output is a tessellated 3MF mesh. The tessellation accuracy can be tweaked to be as precise as needed, so if that's the only constraint this may be applicable.

Thank's for raising the manual! I'll have to invest more time into it :)

fsloth··on Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11
Thank you!

The CAD kernel is written by me apart from the boolean solver for the meshes which is the superb https://github.com/elalish/manifold

To explain a bit more as "do your own kernel" is usually considered more mad than mad-science - this is not done on a whim. I spent over a decade doing CAD at Trimble, developing base tech and CAD offerings (including Tekla Structures and SketchUp). Happy to discuss the architecture more.

OpenCASCADE is included as part of STEP importer though.

Solvespace is a nice reference! One can already use it as prestep to modeling - just export the output as STL or SVG and import it :).
