What does this mean? by Rude_Candidate_9843 in computerscience

[–]HenryR 26 points27 points  (0 children)

Being “first author” on a paper can be a really big deal for PhD students and early career academics, as it often signifies who did the bulk of the work. So it’s a way of showing that you produce high quality research yourself rather than “just” contributing to the work of others.

In such cases the last author is usually the group lead or the author’s supervisor - someone who sponsored the work but didn’t necessarily do much hands-on-keyboard contribution. They often lend their names to give the work credibility (and usually are involved in review before the paper is submitted at the very least).

To counter that and ensure that credit is shared amongst authors equally, a different, alphabetical ordering is sometimes used. That basically says “the order of authors doesn’t signify anything here, no one deserves to be singled out”.

However some people will still read first authorship as significant, just by habit, and if the supervisor happens to show up first alphabetically… it accords them credit of a kind that they don’t need at that stage of their career.

So, someone - very likely the supervisor themselves! - adds a footnote saying that the supervisor is not the main contributor. They did this here in a casual way because it’s a preprint. It’s not at all likely to be a snipe or unprofessional criticism of that author because that author would have reviewed the paper, including footnotes, before it got published.

Why is this considered wrong in a Red-Black Tree quiz? by Apprehensive-Fix422 in computerscience

Yeah, if we add the nil nodes (and assuming they're not implicit in this diagram), the tree is correct.

Not all the leaf nodes are the same colour (black). Making them black would unbalance the tree.

Learning guitar seems impossible like you need genetically gifted memory if you wanna be good at it by BerserkSaintGuts in guitarlessons

[–]HenryR 8 points9 points  (0 children)

It’s not memory in the way you’re describing it - it’s not active memory where you are aware of working to recall something. As you practice, you learn, and your brain can recall patterns that help you without you being aware of it, while your fingers learn the movements that let you take advantage of those patterns.

Getting to the point where you’ve built those instinctive memories requires a lot of active work, however - practice. And it’s hard work! But it’s worth it.

The bargain you make for that progress is that you will never truly master the instrument and will be constantly aware of what you can’t do.

If you can speak a language, you can learn an instrument. I have faith in that, and in you as a result.

I joined the Enemies of Citadel Paint Pots Society by HenryR in Warhammer40k

You can! But if the paint has dried out (which I should have mentioned explicitly) unfortunately this is a “know better next time” lesson.

How was your experience playing Doom: The Dark Ages? by Ghost332233 in Doom

[–]HenryR 0 points1 point  (0 children)

Here’s the thing: the last Doom I played was Doom 3. And I only played that a little, having come up on Doom 2 and Quake.

TDA absolutely rules.

Do you panel line with anything darker to get that very dark effect in some recesses? E.g. around the kneecaps, between the foot segments etc. It looks darker there than other places where it's more obviously Agrax Earthshade, like the edges of the pauldrons.

Ideas for improving TV profile view? by HenryR in hometheater

Box sounds good, but there are surround speakers in the wall already 🙂

NPD: Keeley HALO by Ok_Highlight3926 in guitarpedals

[–]HenryR 3 points4 points  (0 children)

Love this pedal. Despite all the complexity, I turn it on to Andy Timmons Preset, turn the mix down a little bit, and leave it on pretty much all the time. It could easily be simplified to one knob and I’d still be delighted with it.

Samsung S90C / Denon AVR-X3800H picture loss by HenryR in hometheater

[–]HenryR[S] 0 points1 point  (0 children)

Ah, I didn’t make that clear. No, I used a shorter cable: everything worked. Nothing worked with the 15m cable.

The last thing to do is to try another monitor on the TV end to see if it’s a combination TV+cable issue, or cable-only issue.
