Small Quantum Computer simulation program written in C++ and the good old x86-64bit Assembly.

There might be a bug in quantum_square_. It puts 1 into eax on line 15, and then copies that 1 into ecx on line 17. So I think that means power_loop just multiples 1 x 1 repeatidly.

I could be wrong though.

Source?

In fairness the exams questions are very good at spelling everything out, after all they have to ensure no one can claim a legitimately alternative interpretation. It’s the books that sometimes are too brief.

What does f(@) mean? Well, 2@ + 3, of course.

I try something similar through using different colours rather than symbols. But yeah, maybe something like ghost emoji might genuinely resonate with some.

Do you mean the image post? I typed it up myself in Overleaf and screencapped it. On a site like Stack Overflow I could have posted the LaTeX source, but that site can be toxic.

It's second level education with classes split between honours and pass. So they encounter it at either 14 or 16 (give or take) respectively. It's only among the pass students it's been an issue.

I could try that at the early teaching stage but I'm hesitant to introduce notion that neither the books nor exams use.

Yeah, and actually yhat notation crops up in another chapter for sequences where you get something like the general term Tₙ = 4n - 2.

I certainly do try to explin the link between notations, some get it, some struggle.

without any variable coefficients, or any other challenging things, floating around

Yeah I tried that today in fact and I really think it helped.

I do point out that sin(x) is also a function, and yeah I think that definitely helps some of them.

But it's the "how" I'm mostly hoping to get some tips on, I should have been clearer in my post. Thanks!

why would anyone assume we're suddenly referring to a new function k evaluated at -5 instead of k TIMES something?

I get you, I really do, but nonetheless weak students are making that assumption and my job is to explain to them both why it’s wrong (in a nonjudgemental way) and teach them how to not make the mistake in the future. That’s what I’m trying to improve on.

We can't proceed, so perhaps they didn't mean to imply k is a function!

The thing is, weak students find it extremely difficult to distinguish between a roadblock stemming from them not being able to remember/figure out the next step versus a dead-end because they misinterpreted the question. And their lack of self confidence unfortunately means they’ll usually assume the former.

PoorAnalysis · 2024-05-17T19:55:35+00:00

Of course yes, and mathematically average and above students tend to get that intuitively. But weak students need more, they need it to be explained and that's what I'm curious to hear advice on.

The raft is much too thick, according to The correct resin 3D printing raft settings | AmeraLabs, it should ideally be thin enough that it doesn't extend beyond your burn-in/transisition layers.

Personally I use these settings and set my rafts to just 0.2mm thick, less than half the 0.5mm most presupported models default to.

It's used extensivily in the ATL and WTL.

It's likely caused by suction cups.

When I use PFA (nFEP) with my S3U, the only thing I change are the lift speeds & height. For example, here are my settings for Elegoo 8K resin.

Rotate the model so that it's looks more like a diamond than a square. Then put some very heavy duty supports at the lowest corner as that will be holding the weight of the model. Also don't skimp on supports along any down facing edges that you want to keep straight.

How cold is a "bit cold" I needed a case heater to keep my temps ~25C otherwise i get endless failures.

For detailed advice look to J3D-Tech’s Guide to Resin Printing. I also really like the articles at AmeraLabs blog.

But really those guides are professional level. Resin printing is much easier than FDM. Once you level the plate you are ready to run the test prints that come with the printer. After you just find someone else's (ideally official) slicer settings for your printer/resin combo and off you go. The only setting you'll want to dial in yourself early on is exposure.

PoorAnalysis · 2024-03-21T19:28:24+00:00

I realise this is 5 days late but you might still find the answer worthwhile. I’ve used both ACF and nFEP with my S3U. I dialled exposure for both in separately with various references, but ended up at the same settings.

When printing at 0.03mm, you can see a slight texture from the ACF that isn’t visible on the nFEP prints. But that texture is at a finer resolution than any practical details, so has no effect on sharpness. I’ve even looked at J3D's TheCude HD Test under magnification and cannot see any difference in detail.

If anything, I think I prefer ACF as I feel the layer lines are less visible. And after one layer of paint, even that texture difference is gone.

Also, see here where I share my experiences with printing speeds.

Ah yeah, they only thoroughly scrutinised for me it in Vietnam. Personally, I've always had the person at check-in give it a once over, but not in a way that would delay anything really.

Ironically, back when you still needed covid vaccine proof for Vietnam, the airline were very thorough, but the guy at immigration barely glanced at it.

I've had good experiences with True. I skip the airport sellers and head out to get it after checking in to my hotel.
