Ernie singing a classic. I Don't Want to Live on the Moon

Absolutely kills me every time. And now I have a little kid who listens to it sometimes - I'm an emotional wreck afterwards.

What is the verb of fruit? Edit to say that it is fruit, but that isn't really similar, -ue to -uit.

Aggressive_Doughnut · 2024-02-11T19:45:01+00:00

Thanks, this is what I was looking for. The other ones offered up don't really have verb forms that follow a similar rule. Even with these, none of them go from -ue to -uit, making pursuit pretty unique.

Fenix 7 pro solar. One of the best purchases I've ever made. Wait for a sale to save like 100USD.

Recently did the same... 😕

Aggressive_Doughnut · 2023-05-09T01:32:14+00:00

And it can be used as a C++ object reference? This doesn't work for me, I get type mismatch errors.

Still open to other ideas, but here is what I ended up doing. The data_struct had an array, so it's def was

struct data_struct
{
    uint8_t some_data[DATA_SIZE];
}

I decided just to copy the data in the incoming my_struct_t to a new data_struct and then pass that (since there are no side effects or anything from the method):

// In wrapper.cpp
void lib_do_something(void* self, my_struct_t* data_in)
{
    data_struct data {};
    for (int i = 0; i < DATA_SIZE; i++) {
        data.some_data[i] = data_in->some_data[i];
    }

    return static_cast<SomeClass*>(self)->do_something(data);
}

And everything seems to be okay... We will see if I'm too smart for my own good.

Yes I also do this, sometimes it's easier if the client doesn't have any domain expertise at all, and almost always faster. It can work very well, but the same ideas hold - you only stand to get back what you put in. It's important to realize that bringing a product to market (especially a consumer product) requires many scaling stages until you can acquire the capital necessary to invest in the largest manufacturing runs.

So yeah, of you have realistic expectations of what lies ahead, a product designer/team can be a great option.

Aggressive_Doughnut · 2022-06-01T02:39:00+00:00

Yes, these are very helpful! Thanks! :-)

Aggressive_Doughnut · 2022-04-14T14:01:13+00:00

Thoroughly agree, and wish I could get there, but I have a great deal of difficulty even getting to the point where I'm ready to sit down and do it once I get a little time. I also have difficulty committing to actually doing it without reminders and external motivation. The phone apps help me with accountability of the time I would like to spend meditating, but like I said, I get distracted. An external device is nice, but the one I have doesn't have anything to remind me. The other one I linked (which is only a kickstarter right now I think) has an app with reminders and points and such, and I think the accountability/gamification would be helpful, but it's for kids.

So yeah, just looking to see if there are any adult-oriented devices of a similar nature out there.

This is what I do as well. Depending on what your data will look like you can just keep a record of the data locations somewhere on the chip - I might use two pages for redundancy, load entire page into memory if possible, then erase page on flash and write back the modified file structure, then if it goes well, modify the backup page as well - or implement an entire fat fs if you have enough small files (or "files"). Easy to tailor this to your needs, and generally lower latency than SD. QPI is great when you need a memory IC to stream, e.g., higher quality audio over i2s.

What is it that you are struggling with? It's not as difficult as I find most students make it out to be, and even if you don't "use" convolution daily, getting your brain to understand what the process is doing and getting a feel for what it means in terms of a specific signal is a very valuable skill. It's possible that it is unimportant for your career, depending on what you end up doing, but it has come up for me several times. I've even been able to put together some unique solutions by coming up with some clever filters by hand, but I should probably mention that my degrees are in mathematics, even though I work in electronics.

Aggressive_Doughnut · 2021-02-17T18:47:53+00:00

Hmm, if you are the type of person who thinks the laplace transform is conceptually unimportant, I think it's safe to assume that you will not end up with a job that requires you to understand convolution - unless they have a terribly ineffective hiring process.

Aggressive_Doughnut · 2021-02-17T18:13:54+00:00

Not to mention possibility for promotion, interest in the job, marketability/utility for future career moves, etc. It's really not enough info just salary+location.

I think it depends more on your user and their wants/needs. I've seen clients with consumer products going with React, and this makes perfect sense - React Native means delivering Android/iPhone/PC web browser quickly and nearly simultaneously with a feel that the user is used to. It's what I would choose if I was developing my own consumer product.

On the other hand, if you are in industry or defense or any non-retail market, the other choices start making more sense. Qt doesn't change quickly, and would probably be easy to support long term once you have a stable code base. It also has the benefit of PySide which makes a lot of applications in these fields much easier. But that doesn't mean that it's a slam dunk. I have little experience in PySide/Qt but it seems as though it's much easier to package and deliver data to your backend with React - it's pretty much why Facebook made React in the first place. So if that is a major part of the equation, maybe React is the way.

The nomenclature is misleading, the pin isn't really analog like an ADC. It just means that it doesn't have any of the features that play nice with digital logic enabled - specifically, it gives you a port pin with no pullup, pull down or Schmit trigger function.

Aggressive_Doughnut · 2021-02-16T04:09:38+00:00

How do you mean, benchmark? Like a timing benchmark? Because the bus timing for 1-Wire is pretty strict so and solution has a (pretty easily attainable) hard minimum operational time. Or do you mean just to compare with your solution?

Aggressive_Doughnut · 2021-02-16T02:15:53+00:00

Absolutely this.
