In his paper Generics for the Masses Hinze reviews encoding of data type.
Starting from Nat
ANSWER
Answered 2022-Mar-14 at 18:05The difference is the category. Nat
is an initial algebra in the category of types. Rep
is an initial algebra in the category of indexed types. The category of indexed types has as objects type constructors of kind * -> *
, and as morphisms from f ~> g
, functions of type forall t. f t -> g t
.
Then Rep
is the initial algebra for the functor RepF
defined as follows:

Answered 2021-Aug-28 at 15:09According to the java doc of PriorityQueue(PriorityQueue)
Creates a PriorityQueue containing the elements in the specified priority queue. This priority queue will be ordered according to the same ordering as the given priority queue.
So we can extend PriorityQueue
as CustomComparatorPriorityQueue
to hold the desired comparator and the Collection we need to heapify. Then call new PriorityQueue(PriorityQueue)
with an instance of CustomComparatorPriorityQueue
.
Below is tested to work in Java 15.

I want to download/scrape 50 million log records from a site. Instead of downloading 50 million in one go, I was trying to download it in parts like 10 million at a time using the following code but it's only handling 20,000 at a time (more than that throws an error) so it becomes time-consuming to download that much data. Currently, it takes 3-4 mins to download 20,000 records with the speed of 100%|██████████| 20000/20000 [03:48<00:00, 87.41it/s]
so how to speed it up?
ANSWER
Answered 2022-Feb-27 at 14:37If it's not the bandwidth that limits you (but I cannot check this), there is a solution less complicated than the celery and rabbitmq but it is not as scalable as the celery and rabbitmq, it will be limited by your number of CPU.
Instead of splitting calls on celery workers, you split them on multiple processes.

QUESTION
I've been putting together my own disassembler for Sega Mega Drive ROMs, basing my initial work on the MOTOROLA M68000 FAMILY Programmer’s Reference Manual. Having disassembled a considerable chunk of the ROM, I've attempted to reassemble this disassembled output, using VASM as it can accept the Motorola assembly syntax, using its mot
syntax module.
Now, for the vast majority of the reassembly, this has worked well, however there is one wrinkle with operations that have effective addresses defined by the "Program Counter Indirect with Index (8-Bit Displacement) Mode". Given that I'm only now learning Motorola 68000 assembly, I wanted to confirm my understanding and to ask: what is the proper syntax for these operations?

QUESTION
I would like to be able to robustly stop a video when the video arrives on some specified frames in order to do oral presentations based on videos made with Blender, Manim...
I'm aware of this question, but the problem is that the video does not stops exactly at the good frame. Sometimes it continues forward for one frame and when I force it to come back to the initial frame we see the video going backward, which is weird. Even worse, if the next frame is completely different (different background...) this will be very visible.
To illustrate my issues, I created a demo project here (just click "next" and see that when the video stops, sometimes it goes backward). The full code is here.
The important part of the code I'm using is:

Answered 2022-Jan-21 at 19:18The video has frame rate of 25fps, and not 24fps:
After putting the correct value it works ok: demo
The VideoFrame api heavily relies on FPS provided by you. You can find FPS of your videos offline and send as metadata along with stop frames from server.
The site videoplayer.handmadeproductions.de uses window.requestAnimationFrame() to get the callback.
There is a new better alternative to requestAnimationFrame. The requestVideoFrameCallback(), allows us to do per-video-frame operations on video.
The same functionality, you domed in OP, can be achieved like this:
QUESTION
I'm parsing a language that doesn't have statement terminators like ;
. Expressions are defined as the longest sequence of tokens, so 5-5
has to be parsed as a subtraction, not as two statements (literal 5
followed by a unary negated -5
).
I'm using LALRPOP as the parser generator (despite the name, it is LR(1) instead of LALR, afaik). LALRPOP doesn't have precedence attributes and doesn't prefer shift over reduce by default like yacc would do. I think I understand how regular operator precedence is encoded in an LR grammar by building a "chain" of rules, but I don't know how to apply that to this issue.
The expected parses would be (individual statements in brackets):
...ANSWER
Answered 2022-Jan-04 at 06:17The issue you're going to have to confront is how to deal with function calls. I can't really give you any concrete advice based on your question, because the grammar you provide lacks any indication of the intended syntax of functions calls, but the hint that print(5)
is a valid statement makes it clear that there are two distinct situations, which need to be handled separately.

QUESTION
I am looking for a way to detect if the device I am using can support Dolby Atmos sounds.
After searching around I found this call.
https://github.com/w3c/media-capabilities/blob/main/explainer.md#spatial-audio
...ANSWER
Answered 2021-Dec-24 at 06:57Detecting the codec doesn't necessarily detect whether the system can support Dolby Atmos
Correct.
What reliable way is there to detect if your system will truly support Dolby Atmos whether its with a receiver or a Dolby Atmos compliant sound bar.
Unfortunately, this undetectable from the browser.
The browser itself and even the OS doesn't always know what is downstream. Sorry for the bad news!
QUESTION
I am trying to find a more efficient solution to a combinatorics problem than the solution I have already found.
Suppose I have a set of N objects (indexed 0..N-1) and wish to consider each subset of size K (0<=K<=N). There are S=C(N,K) (i.e., "N choose K") such subsets. I wish to map (or "encode") each such subset to a unique integer in the range 0..S-1.
Using N=7 (i.e., indexes are 0..6) and K=4 (S=35) as an example, the following mapping is the goal:
0 1 2 3 --> 0
0 1 2 4 --> 1
...
2 4 5 6 --> 33
3 4 5 6 --> 34
N and K were chosen small for the purposes of illustration. However, in my actual application, C(N,K) is far too large to obtain these mappings from a lookup table. They must be computed on-the-fly.
In the code that follows, combinations_table
is a pre-computed two-dimensional array for fast lookup of C(N,K) values.
All code given is compliant with the C++14 standard.
If the objects in a subset are ordered by increasing order of their indexes, the following code will compute that subset's encoding:
...ANSWER
Answered 2021-Oct-21 at 02:18Take a look at the recursive formula for combinations:
Suppose you have a combination space C(n,k)
. You can divide that space into two subspaces:
C(n-1,k-1)
all combinations, where the first element of the original set (of lengthn
) is presentC(n-1, k)
where first element is not preset
If you have an index X that corresponds to a combination from C(n,k)
, you can identify whether the first element of your original set belongs to the subset (which corresponds to X
), if you check whether X
belongs to either subspace:
X < C(n-1, k-1)
: belongsX >= C(n-1, k-1)
: doesn't belong
Then you can recursively apply the same approach for C(n-1, ...)
and so on, until you've found the answer for all n
elements of the original set.
Python code to illustrate this approach:

ANSWER
Answered 2021-Nov-17 at 05:12Only a few specific GPR instructions have VEX encodings, primarily the BMI1/BMI2 instructions that were added after AVX already existed. See the list in Table 2-28, which has ANDN, BEXTR, BLSI, BLSMSK, BLSR, BZHI, MULX, PDEP, PEXT, RORX, SARX, SHLX, SHRX
, as well as the same list in 5.1.16.1. For example, andn
's manual entry lists only a VEX encoding, and
's manual entry doesn't list any.
So Intel (unfortunately) didn't introduce a brand new three-operand alternate encoding for the entire instruction set. They just introduced a few specific instructions that take three operands and use VEX for it. In some cases these have similar or equivalent functionality to an existing instruction, e.g. SHLX
for SHL
with a variable count, and so effectively provide a three-operand version of the previous two-operand instruction, but only in those special cases. There are not equivalent instructions across the board.
The "old style" two-operand form remains the only version of the add
instruction. However, as fuz points out in comments, lea
can be a good way to add two registers and write the result to a third, subject to some restrictions on operand size.
See Using LEA on values that aren't addresses / pointers? for more general things LEA can do, like copy-and-add a constant to a register, or shift-and-add. Compilers already know this and will use lea
where appropriate, any time it saves instructions. (Or with some tune options like -mtune=atom
for old in-order Atom, will use lea
even when they could have used add
.)
If more flexible encodings of common integer instructions other than add existed, like and
/xor
/sub
, gcc -O3 -march=skylake
would already be using them in its own asm output, without needing inline asm. Or if alternative instructions could get the job done, like lea
for add
, would be doing that, so it makes sense to look at compiler output to see what tricks it knows. Trying it yourself would make more sense as something to play around with in a stand-alone .s
file that just makes an exit system call, or just to single-step, removing the complexity of using inline asm. (GAS by default doesn't restrict instruction-sets. gcc -march=skylake
doesn't pass that on to the assembler, as
.)
In your inline asm, your c
operand should be to output-only: =r
instead of +r
. The old value is overwritten, so there's no need to tell the compiler to produce it as an input. (Like you said, you want c = a+b
not c += a+b
.)
Using a single lea
as the asm template means you don't need a =&r
early-clobber output, because your asm will read all its inputs before writing that output. In your case, having it as an input/output was probably stopping the compiler from choosing the same register as one of the inputs, which could have broken with mov; add
.
