QUESTION
First time actually using anything to do with swing - sorry for the poor code and crude visuals!
Using swing for a massively over-complicated password checker school project, and when I came to loading in a JMenuBar, it doesn't render properly the first time. Once I run through one of the options first, it reloads correctly, but the first time it comes out like this:
First render attempt
But after I run one of the methods, either by clicking one of the buttons that I added to check if it was just the JFrame that was broken or using one of the broken menu options, it reloads correctly, but has a little grey bar above where the JMenuBar actually renders: Post-method render
The code for the visuals is as follows:

I am currently trying to write some ECS in C++. Inside my ECS (Entity component system), I have a set of entities which all have a set of components. Like a position, rotation, etc.. What I want to do is implement a function which returns an iterator to iterate over the entities which fullfill a few requirements. These requirements are grouped into the following categories:
- required
- requires_one
- excludes
Ideally, I would call the function like this:

I am trying to make a popup for messages such as "Action completed" and I want a button on it to close the popup (A simple OK which quits only the popup). It also sometimes moves behind the window which is annoying. I have some code for the button but it has an issue with the geometry of the shape since the shape isn't exactly defined as it is variable through the size of font and text length.

I want to create a .wasm
file which still has the function names exported when compiled.
ANSWER
Answered 2021-Jun-15 at 09:04If you plan to write a lot of WASM in Go, you might want to consider compiling with TinyGo, which is a Go compiler for embedded and WASM.
TinyGo supports a //export
or alias //go:export
comment directive that does what you're looking for.
I'm copy-pasting the very first example from TinyGo WASM docs:

QUESTION
One can use _mm256_packs_epi32. as follows: __m256i e = _mm256_packs_epi32 ( ai, bi);
In the debugger, I see the value of ai: m256i_i32 = {0, 1, 0, 1, 1, 1, 0, 1}
. I also see the value of bi: m256i_i32 = {1, 1, 1, 1, 0, 0, 0, 1}
. The packing gave me e: m256i_i16 = {0, 1, 0, 1, 1, 1, 1, 1, 1, 1, 0, 1, 0, 0, 0, 1}
. The packing is interleaved. So we have in e first four numbers in ai, first four numbers in bi, last four numbers in ai, last four numbers in bi in that order.
I am wondering if there is an instruction that just packs ai and bi side by side without the interleaving.
vpermq after packing would work, but I'm wondering if there's a single instruction to achieve this.
...ANSWER
Answered 2021-Jun-15 at 08:28No sequential-across-lanes pack until AVX-512, unfortunately. (And even then only for 1 register, or not with saturation.)
The in-lane behaviour of shuffles like vpacksswd
and vpalignr
is one of the major warts of AVX2 that make the 256-bit versions of those shuffles less useful than their __m128i
versions. But on Intel, and Zen2 CPUs, it is often still best to use __m256i
vectors with a vpermq
at the end, if you need the elements in a specific order. (Or vpermd
with a vector constant after 2 levels of packing: How do I efficiently reorder bytes of a __m256i vector (convert int32_t to uint8_t)?)
If your 32-bit elements came from unpacking narrower elements, and you don't care about order of the wider elements, you can widen with in-lane unpacks, which sets you up to pack back into the original order.
This is cheap for zero-extending unpacks: _mm256_unpacklo/hi_epi16
(with _mm256_setzero_si256()
). That's as cheap as vpmovzxwd
(_mm256_cvtepu16_epi32
), and is actually better because you can do 256-bit loads of your source data and unpack two ways, instead of narrow loads to feed vpmovzx...
which only works on data at the bottom of an input register. (And memory-source vpmovzx... ymm, [mem]
can't micro-fuse the load with a YMM destination, only for the 128-bit XMM version, on Intel CPUs, so the front-end cost is the same as separate load and shuffle instructions.)
But that trick doesn't work work quite as nicely for data you need to sign-extend. vpcmpgtw
to get high halves for vpunpckl/hwd
does work, but vpermq
when re-packing is about as good, just different execution-port pressure. So vpmovsxwd
is simpler there.
Slicing up your data into odd/even instead of low/high can also work, e.g. to get 16 bit elements zero-extended into 32-bit elements:
QUESTION
I'm trying to make a string that will write itself letter by letter until completing the sentence, and the speed of appearing each letter is based on an input that varies from 1 to 10. At the end of the string, it will blink for 5 seconds until that an alien will appear. My idea was to create a setInterval to add the letters and when the counter added the array size it would return the final animation of the loop with the new setInterval call, and before it was called again it had already been cleared, and called again in a recursion by setTimout callback to maintain the infinite loop. But it's not reaching setTimout, why?

Another branch was created on the upstream repo. Let's call it features/demo. Three branches now exist, Master, Develop and features/demo.
My forked repo only has Master and Develop. The forked repo is set as the origin and is my local cloned copy.
How do I pull the upstream branch into my local? Every time I try it wants to merge into Develop or Master because that's what any new branch I make is checked out from.

That's the definition of pull as delivered (with factory-default options): fetch and merge.
You just want to fetch. At the factory default settings,
