This insightful blog post seems to refer to this article. I hope the article is an isolated case. Although it's undeniable that scientific illiteracy is spreading.

There's an old youtube channel by "Avamogal" (apparently "a mom to 7 boys. 10 grandkids 8 boys, 2 girls") which is full of great collages of Buster clips, with interesting music backgrounds. Recommended.

Sadly it seems the channel hasn't been active for 6 years or so...

I have read the FAQ of KDE Neon: it is well made and answers ground questions like "Is it a distro?" or "Can I turn Kubuntu into KDE Neon?"

...And yet I'm confused, because I'm just a newbie in the Linux world. For instance, when they say "on top of a stable base" I don't know what's meant as a "base".

I think I understand that it isn't a distro, but it fascinates me that it's meant to be installed from an ISO or similar, just like a distro.

I wonder if any of you can explain:

• What is it, in different words?
• Why is it "implemented" as it is?
• Are there any other "quasi-distros" like KDE Neon out there?
• Do you use it? how has your experience with it been?

Cheers!

If I want to link to a community X on a Lemmy instance Y.zzz, I know I should use the link /c/X@Y.zzz, which will redirect to the copy of the instance on the server where the user has the account.

What is the analogous way to link to a post? For example this post has address lemmy.ca/post/1866360 but what link should I give to users on another instance, so that they can see the post in their instance?

The article introduces a dynamic cosmological constant in the current ΛCDM cosmological model to account for some data from the James Webb telescope. The new model would have the age of the universe at ~27 billion years.

This is interesting. Unfortunately some popular science magazines are already presenting it as a fact...

Some large datasets are pushing memory and some functions I'm writing to the limit. I wanted to ask some questions about subsetting, of matrices and arrays in particular:

1. Does defining a variable as a subset of another lead to copy? For instance

x <- matrix(rnorm(20*30), nrow=20, ncol=30)
y <- x[, 1:10]

Some exploration with object_size from pryr seems to indicate that a copy is made when y is created, but I'd like to be sure.

2. If I enter a subset of a matrix/array as argument to a function, does it get copied before the function is started? For instance in

x <- matrix(rnorm(20*30), nrow=20, ncol=30)
y <- dnorm(0, mean=x[,1:10], sd=1)

I wonder if the data in x[,1:10] are copied and then given as input to dnorm.

I've heard that data.table allows one to work with subsets without copies being made (unless necessary), but it seems that one is constrained to two dimensions only – no arrays – that way.

Cheers!

There are two kinds of colours that appear in each torrent entry in Nyaa's listings:

• One for the rectangle in the "Category" column. I see many different colours there: purple, red, dark and light grey, green, orange, dark and light yellow...

• One for the whole row. Here I've only seen three different colours so far: white, green, red.

Do these colours, especially the second, mean anything?

Nyaa's Help page mentions the meaning of four "torrent colours": green, red, orange, grey. But they don't say where these colours appear. If they mean the row colour, then I've never seen an orange or grey one. So I'm very confused. Maybe the Help page is outdated?

OK, not a life-or-death matter, but I've been curious about this for a long time...
