QUESTION
Situation: I am working with a crypto library called embedded disco, I have a demo working on my PC but when porting it over to the MCU I get a hard fault when executing a library procedure. In the faulting code, the library is trying to simply copy the content of one strobe_s struct into another strobe_s. This is done twice: once for s1 and once for s2. For s1, the library simply assigns the dest. struct to the source struct. For s2 however, such an assign gave a hard fault. As the Cortex-M ISA requires aligned memory accesses, I reckoned that replacing the assignment with a memcpy should fix the problem. Nevertheless, simply stepping into memcpy using the debugger results in a hard fault! I.e. I have a breakpoint at the line with the memcpy and when stepping inside the fault handler is called! I have used memcpy to fix misaligned memory accesses in other parts of the code just fine...
MCU: STM32L552ZET6QU
Faulting code:
The code below is my modification of the original library code where the assignment to *s2 was replaced by a memcpy. The original code from the library's github was:

I'm trying to time the execution of a function but it always returns 0ns, which is hard to believe. Added a 1ns sleep in between but it does strange things (when uncommented). Here is the code:
ANSWER
Answered 2021-Jun-08 at 13:43The effective precision of the time package is not that great. Even though the value goes to "nanosecond precision", that doesn't mean the time actually updates every nanosecond. From my own testing, the resolution of the current time is effectively 100 nanoseconds and only updates about every 0.5 milliseconds. This will most likely vary depending on your OS, hardware, and other factors.
If you want to time things the right way, read about benchmarks in the testing package. Benchmarks offer better precision because they run your code multiple times in a loop, to get the average execution time. This allows you to measure times which would be too small when not aggregated (like in your case).
QUESTION
what i need to do is to connect two jradiobuttongroups and a combobox to a jbutton and when i click the jbutton the total of all the options appear in a textfield.
****(edit)by total i meant to say that you add up the chosen options(one for each category). You connect them to the calcular importe jbutton and in the ver dialogo jbutton you create a dialog window that shows you the microprosessor you selected and the final price ***

...ANSWER
Answered 2021-May-23 at 08:59What you would want to do is exactly what you did with the JTextField...declare all pertinent Swing components as class member variables so that they can be accessed anywhere within the scope of the Ventapc class. Once this is done then you can create a method to verify that all required fields have a selection, maintain a sum from those selections, and insert the total price into the available JTextField (textField). Something like this:

I use my custom dataset class to convert audio files to mel-Spectrogram images. the shape will be padded to (128,1024). I have 10 classes. after a while of training in the first epoch, my network will be crashed inside the hidden layer in GRU shapes due to this error:
...ANSWER
Answered 2021-May-11 at 02:58Errors like this are usually due to your data changing in some unexpected way, as the model is fixed and (as you said) working until a point. I think your error comes from this line in your model.forward() call:

QUESTION
I'd like to know how to do 2 execution plans: "traditional" execution plan joins (A with B) and then C. The "new" plan joins (A with B) then (A with C) and then joins the result of those joins so there would be 3 joins. How would I code the traditional and new plan in Oracle SQLPlus given the code below? I also need to measure the time complexity of both methods to show that the new plan takes less time, which I believe I just do with set timer on; The joins can be on whatever attributes work. Same with select statements. I made a artist, b album, c track, and d played.
Here's the database:
...ANSWER
Answered 2021-Apr-18 at 06:13Your question doesn't make a lot of sense, because it's imposing bizarre restrictions that we can't really assess, but I don't mind telling you how to join two joins
You already know how to join three tables in the normal/traditional/sensible sense. Here's how to join them as you ask:
QUESTION
I've a stacklayout in a qt5-python program with 3 pages. I change the page by clicking on three icons and it works perfectly.
...ANSWER
Answered 2021-Apr-09 at 17:38QStackedLayout works with "pages" which are reusable, just like a "tabbed" interface does (in fact, QTabWidget uses a private QStackedWidget, which is based on QStackedLayout).
Considering the fact that pages are reusable, your issue is that you're not actually switching to the pages, but you're continuously adding a new page every time.
While dynamic creation of pages is obviously possible, even for optimization purposes, in your case you don't need that since you only have 3 pages.
Since those 3 pages will probably have their own "static" layout, a better solution is to create separate subclasses for each page, which allows creating specific function to update the data whenever required. This is a far better approach than creating single functions that do almost the same thing when creating/switching pages, and you can have a single interface to access/set the data from and to each page.
This is a possible implementation:

If users rate items directly, this is known as explicit feedback. Fit the recommender with:. IDs can be integers, strings, or any other data type. If users don’t rate items directly (for instance, they’re purchasing items or reading posts), this is known as implicit feedback. Leave out the rating. Get user-based recommendations - “users like you also liked”. Get item-based recommendations - “users who liked this item also liked”. Use the count option to specify the number of recommendations (default is 5). Get predicted ratings for specific users and items.
