kandi X-RAY | r8 Summary
Laravel has always been missing a package like this, that supports dynamic rating with multiple Rating Types (ex. Like in Amazon or any e-commerce platform, Quality Rating, Customer Service Experience Ratings, etc.) with Integrated Reviews and Recommend Functionality. The main Ideology behind this package is to make it easily adaptable for everyone's use case. Reviews & Ratings system for Laravel 7. You can rate any of your models.

Today AS 4.2 hit stable. I updated my gradle distribution url to 6.7.1 like I was told, and Android Gradle Plugin to 4.2.0. If I update the AGP, my app no longer builds.
I don't understand the error or know where to look. Here is the stacktrace:

Answered 2021-May-05 at 14:39First thought: Probably mixed up index number with number of elements?
But to be certain I have to see the actual code where the exception is thrown.

QUESTION
I'm trying to get the values of the assembly registers rdi, rsi, rdx, rcx, r8, but I'm getting the wrong value, so I don't know if what I'm doing is taking those values or telling the compiler to write on these registers, and if that's the case how could I achieve what I'm trying to do (Put the value of assembly registers in C variables)?
When this code compiles (with gcc -S test.c)
ANSWER
Answered 2021-Jun-07 at 01:19Your code didn't work because Specifying Registers for Local Variables explicitly tells you not to do what you did:
The only supported use for this feature is to specify registers for input and output operands when calling Extended
asm(see Extended Asm).
Other than when invoking the Extended
asm, the contents of the specified register are not guaranteed. For this reason, the following uses are explicitly not supported. If they appear to work, it is only happenstance, and may stop working as intended due to (seemingly) unrelated changes in surrounding code, or even minor changes in the optimization of a future version of gcc:
- Passing parameters to or from Basic
asm- Passing parameters to or from Extended
asmwithout using input or output operands.- Passing parameters to or from routines written in assembler (or other languages) using non-standard calling conventions.
To put the value of registers in variables, you can use Extended asm, like this:

I have a simple fasm program, in this program I get some zeroed memory from windows through VirtualAlloc. I then have a procedure where I simply set up the parameters and make a call to StretchDIBits passing a pointer to the empty memory buffer. I therefore expect the screen should be drawn black. This however is not the case, and I can't for the life of me figure out why.
Below is the code.

QUESTION
I try to put Apache Arrow vector in Ignite, this is working fine when I turn off native persistence, but after I turn on native persistence, JVM is crashed every time. I create IntVector first then put it in Ignite:
...ANSWER
Answered 2021-Jun-01 at 11:11Apache Arrow utilizes a pretty similar idea of Java off-heap storage as Apache Ignite does. For Apache Arrow it means that objects like IntVector don't actually store data in their on-heap layout. They just store a reference to a buffer containing an off-heap address of a physical representation. Technically it's a long offset pointing to a chunk of memory within JVM address space.
When you restart your JVM, address space changes. But in your Apache Ignite native persistence there's a record holding an old pointer. It leads to a SIGSEGV because it's not in the JVM address anymore (in fact it doesn't even exist after a restart).
You could use Apache Arrow serialization machinery to store data permanently in Apache Ignite or even somewhere else. But in fact after that you're going to lose Apache Arrow preciousness as a fast in-memory columnar store. It was initially designed to share off-heap data across multiple data-processing solutions.
Therefore I believe that technically it could be possible to leverage Apache Ignite binary storage format. In that case a custom BinarySerializer should be implemented. After that it would be possible to use it with the Apache Arrow vector classes.
QUESTION
I was trying to make an auto clicker using Mouse and keyboard modules and tkinter as the gui and wrote this code
...ANSWER
Answered 2021-May-30 at 16:36The reason why GUI does not show up is that before the code hits mainloop() it goes into a infinite loop(while loop) and it cannot reach mainloop and hence window does not show up and events are not processed. So what you should do is get rid of while. One way is to use after() method to emulate while.

QUESTION
I am having difficulty with reverse engineering this assembly code to deduce the values of the array's dimensions.
I am given
...ANSWER
Answered 2021-May-28 at 19:16Indexing a 2D array has to scale the first index by sizeof(struct vec3[A]): array1 is an array of arrays, and each smaller array has A elements. So you look at the asm and see what it's multiplying by.
Given, struct vec3 array1[2][A];,
array1[i1][j1].x is the same address math as for a flat 1D array: array1[ (i1*A) + j1 ].x. And in C, we index by element not bytes, so the asm also has to scale by sizeof(struct vec3). That's clearly what the sal $4, %reg instructions are doing, because after padding for alignment the struct size is 16 bytes.
Notice that the leading dimension [2] doesn't come into the calculation at all; that just tells you how much total space you have. It's the later dimensions that set the geometry; the stride between the the same column in different rows.
If you don't already see how that C would compile for different A and B values, try it with some sample ones and see what changes when you increase A or B by 1. https://godbolt.org/ is ideal for playing around with stuff like that.
e.g. https://godbolt.org/z/zrecTcqMs uses prime numbers 3 and 7 for A and B, so even without changing the numbers, you can see which are multiples of which.
Except GCC is too clever for it to be that simple: it's multiplying using one or two LEA, e.g. RCX + RCX*2 = RCX*3, not using imul $3, %rcx, %rdx for example. If you use large non-simple numbers like 12345 for A and B, you'll see actual imul. https://godbolt.org/z/4G3qc5d5E.
I used gcc -fpie to make it use position-independent code: a RIP-relative LEA to get array addresses into registers, instead of addressing modes like array1(%rcx, %rdx, 2) which require the array address (in the .data or .bss section) to fit in a 32-bit sign-extended disp32 in the machine code.
I also used __attribute__((ms_abi)) to use the Windows x64 calling convention like your code does, since GCC on the Godbolt compiler explorer is targeting Linux. (MSVC is the only compiler on Godbolt that targets Windows by default, but it won't output in AT&T syntax.)
