Hi, you wrote that you are already using a parameter pack in the function rgbpixel::channel. Where would that be? Please post the signature(s) of rgbpixel::channel. Is your code somewhere so I could have a look?

Sure
gfx/include/gfx_pixel.hpp at master · codewitch-honey-crisis/gfx · GitHub[^]
Pixel is at line 504
template<typename... ChannelTraits>
struct pixel {
...
This parameter pack is effectively passed through to each of the metadata query templates, as well as any function that access pixel data, like the implementation of channel<>()

Are you going to post the reddit solution?

Similarly, when I was still working, every once in a while I'd leave a comment like:
//Seems like there should be a better way to do this, but I couldn't think of it.
//< explanation of what the code is trying to do >

Yes, absolutely. Some days I am just not inspired. On those days, I just crank out something and hope I can come back later to fix it. I often find that the next time around, I have a much better solution. The problem is, this only works if your employer is understanding enough to let you run your own show. Such employers are rare, of course.

I asked him if he could explain the gaps in his resume.
He said "yeah, they are spaces and you type them using the space bar."
I hired him on the spot!

As a Charles Bukowski character once said when an interviewer asked about
the gaps in his resume, "Anybody can work all the time!"

I like to imagine I would have merely replied "Yes."

At football tournament's England should be represented by it's media, it would be an all star team.

I sometimes think the media should form the next government; they clearly have all the answers....

That's true wherever you are in the world, too.

Even that's open to debate these days, sadly. There are some fearsome reputations from groups other than the English followers.

I see no reason to reward laziness.

Especially doing front end applications that interface with large databases ?
Dealing with large SQL requests ?
Anything related to UI/UX ?

Hopefully the back-end API's support pagination and sophisticated searching. (That's a UI/UX clue as well.)
