Sorry, why wouldn’t I write in the native language?

It doesn’t make any sense that you’d need tongs to make tongs; just hold the workpiece. Maybe you cant draw out the reins quite so much on your first one. (Ok im a modern blacksmith that assumes the existence of rolled bar as a source material)

But a hammer! How do you make a hammer without a hammer?

I’m so glad to hear you say that, i was carrying it around while slogging through it and everyone else who saw exclaimed how good they’d heard it was. I do think the sequel is better, I can suspend my disbelief more and found parts of it honestly thrilling

Did your sense of taste change after your surgery? My sister is considering a similar procedure and is concerned that everything could start tasting like hot garbage.

The Nim compiler used ropes internally for years, until recently[0] because removing them reduced memory consumption and decreased compile times, so ymmv

The ecosystem is smaller than some, but wrapping libraries is mostly automatable, and there is tooling to assist interop with python, c, and c++

yes, Nim has move semantics, but takes care of you more than c++ does. for example, if you use an object that was previously moved, you dont get garbage, the compiler turns the first move into a copy (and tells you)

the relevant docs are here: https://nim-lang.org/docs/destructors.html

they should be able to. same physics applies, right? poles dont have to be as thick or as deep to resist the same torque, and if you could somehow make the pales curvy/corrugated, they could be thinner, too.

It may not come as a complete surprise that the economics of metals are more complex.

Aluminium, was so expensive until the Hall/(that other guy) process was developed, that it was used for jewellery [1].

Even today it's expensive and difficult to reduce Al ore to metal, which is a supply side problem.

I came here to share that the importance of using contemporaneous materials, if not methods, was highlighted for me when I worked on Bath cathedral and saw how the victorian 'improvements' of using iron rather than wood to fix the stonework caused much damage a century later; iron expands when it rusts and causes cracking.

Then I see linked in that article that Notre Dame was a very early example of using iron staples! I can only think that they were used away from water, unlike Bath, where the repairs were on the window fixings.

Not any kind of chemist, but I'm seeing molybdenum disulfide plus (metal) coated on alumina support used as a catalyst, as well as magnetic Al/Fe composite nanoparticles used for same. Usually the metal is something more punk rock, like platinum, cobalt, or ruthenium, but copper is an obvious choice on the poisonous/cheap axis

Metallic aluminium is insanely reactive and any Aluminium exposure will always be in the form of oxides or hydroxides. It's disingenuous to suggest that it is inert in this form, especially given that the point of the exercise is active, complex, catalysed photochemistry.

> If you have children or a significant other, think how much time you spend with them. Do you get burnt out from it?

New daughter. Love her immensely. So happy. Burnt out? YES.

Olive oil absolutely degrades in light. Even in dark bottles. Really high quality olive oil is sold in opaque ceramic containers.

You can get third party rp2040 modules or just the raw chip, easily. Not with the (proprietary licensed?) Wifi stuff, and definitely not official.

Reading the manual it looks like it automatically pulls the electrode back away from the workpiece after the arc is struck.

Correct. In a stick welder I care about: working all day, in the rain, up a ladder, at 130A. For ease/quality of the weld, I pay for quality welding rods, not more settings.

No it's not, there's no spool. It's tungsten electrode, inert gas. Feed wire and electrode diameters are, like, 0.3mm

Not fundamentally different, technically, just optimized for that low end. I think this model maxes out at 13A. And you're looking at your weld *through a microscope*.

That process is called /decarburization/

I grew up in a family of classical musicians, got a degree in music, and was briefly a professional classical musician myself. So my advice may be very out of touch with the experience of someone learning for the first time, but my experiences learning beyond European classical music theory left me feeling insulted.

The basics of music theory are presented as though they are the foundations upon which all subsequent music is derived. In fact, teaching scales and chords is like teaching that the electron orbits the nucleus - a 'simplification'. There _are_ real psychoacoustic truths, alongside equally fascinating historical forces, that underpin music theory.

Learn the language and idioms of music theory, by all means, but don't think of it as being in any way true. Its a syncretist cargo cult of hacks and rules of thumb handed down by centuries of men with dubious motives.

I recommend Adam Neely on YouTube, he illustrates music theory concepts clearly, engagingly, and with an appropriate skepticism for received wisdom.

Here's his discussion of some more political criticisms of music theory: https://youtu.be/Kr3quGh7pJA

I recommend Sethares' _Tuning, Timbre, Spectrum, Scale_ to anyone interested in the underpinnings of why some notes sound good together and others don't.

While it saddens me to hear what you're saying, I literally left my career as a blacksmith for embedded because even the interesting bespoke projects are all going to CNC. I'd be interested in your project, sounds like it's a rare intersection of my domains of interest

Ok this changed my mind about this tech. Tig welding really takes thousands of hours to learn, you do get limited by how much material you can burn through

... They sit down and wait for Beckett to show up.

I agree, I prefer Nim's alternate syntax for this sort of stuff:

    var signal*: (cint,(cint)->void) -> (cint)->void

I couldn't agree with you more.

I work with artists who build great teetering cathedrals on top of Arduino(and Processing), and it's really difficult to incrementally move to a more serious solution once things have reached a certain level

Specifically the things it does that bake in bad habits are:

- Encouraging globals

- Everything in one namespace

- Arduino is not C++

- not needing pre-definitions(mostly) and spamming all .pdes into the same file leads to tangled code that's really hard to pull apart into modules, even if it's separated in tabs in the Arduino editor

- delay: not composable!

- for esp specifically: Thinking in terms of a single loop function Vs multiple rtos threads

- the ide is terrible, and encourages a copy-paste workflow because that's how best to work within it

I've seen an 8kph limit on inland waterways. But it was very unusual to see
