dm319··on Doubts creep in about wisdom of ‘no-kids zones’ in South Korea
Anyone who is child free still has a vested interest in the future generation.
dm319··on Why isn't Titan classed? (2019)
Do you know in what way it was 'acoustic'? I.e. was it listening for sounds, or was it more like sonar?

When I heard Cameron speaking about this recently, I thought he was referring to two different materials being used, rather than the carbon fibre per se.

Ballast tanks don't work at these depths because of the extreme pressure, which is why all these deep sea vehicles are submersibles rather than submarines. In fact I think if a submarine goes below a certain depth then it can't adjust its buoyancy to return to the surface again, but I am also not a sub nerd.

It's funny you should bring up the shuttle, I don't know if you've seen the documentary on the challenger disaster? Yet another case of managers not heeding the concerns of engineers.

Boeing max, theranos..

dm319··on The rule says, “No vehicles in the park”
The majority of comments and people participating in a forum generally both have common sense and are good actors. It's the borderline cases that are difficult, and of course there are boundary pushers of all sorts persuasions. Some are right, some are bad actors.
dm319··on Windows NT on 600MHz machine opens apps instantly. What happened?
I was just reading this week about someone trying to get their UHK keyboard to launch an application on Windows by producing a sequence of keys starting with the Windows key. They needed to put in a delay to get this to work, and it reminded me of my frustrations launching programs in Windows as the start menu takes its sweet and variable time. Not least because I know the technology has been focused on getting adverts into the start menu.
dm319··on Plain text journaling in Vim
I like this. I use vimwiki for my notes, but I'm struggling to get any sort of todo list working these days.

For a while I had some scripts that converted my vimwiki files to html and saved them to Google drive, and it would also find and extract pending todos.

As people have mentioned it requires a laptop with linux and vim on it, which is not very compatible with my work (windows machines) or my phone.

I wonder if buying something like a GPD pocket will solve this.

dm319··on Reddit Strike Has Started
I think we have to stop chasing growth like this. It's destructive to many things.
dm319··on Reddark: Website to watch subreddits going dark
It's a shame because of all the social media platforms, reddit is one of the best. There isn't so much grandstanding (I couldn't tell you a single username on reddit), and the ability to rapidly create special-interest subreddits means that discussion revolves around the topic, on the whole.

I left facebook because it became a place where people I knew spent their time curating a false virtual identity of themselves and seemed to become a place to establish social status rather than any meaningful conversation. I've avoided instagram for the same reason. Twitter seemed a good platform for open discussion, but now it looks like a pit of misery.

Mastodon is pleasant and friendly, but I find it hard to talk about the topics I am interested in. Like twitter it is more person-focused. What would be nice is if there is a way to cut across it easily in a more topic-focused way. Hashtags are present, but they don't have the feel of a forum. For positive or negative, there isn't any 'algorithm' on mastodon other than reverse chronology, and I think that does miss out on highlighting interesting topics and replies. Also there is no moderation or guidelines for hashtags, a feature which helped guide people to the right discussions in reddit.

The number is deliberately close but not the same as pi/2.

See here: https://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv017.c...

And you can compare to wolfram alphas result.

The answer to Cos(1.57079632) (in radians) will give you a clue as to how your calculator does it.

dm319··on Free42 – An HP-42S Calculator Simulator
I've used the free42 (and newer plus42) app on my phone for nearly a decade now. In the UK, RPN calculators were pretty much not seen in the school place. We had Casios, Sharps, and those really into maths tended to get TI graphing calculators.

The beauty of RPN is that you can get the data into the calculator before you figure out how you're going to calculate the thing you want to know. The roll and x<>y help you to manipulate the data, and once you get the hang of it, algebraic notation feels slow and unintuitive (back pedalling through notation to get brackets in place for example).

You also get intermediate results to sense-check as you're going along.

I recently got a DM42 from swissmicros, which is a real life calculator running free42. It is beautifully made, and it makes me happy that I have it. But my job isn't in one place, so I still probably use the phone app more.

dm319··on The Legend of Zelda: Tears of the Kingdom Release
That's a weird comment because botw seemed huge to me, and this uses the same map.

Either way, picking it up today!

dm319··on Termux is an Android terminal emulator and Linux environment app
Ah ok, looks like I've been doing it wrong but that's great to know.

Reading around on Nix, I'm starting to wonder if I should use a functional package manager for a functional language...

One issue I've had with analysis projects is that when my R system upgrades I find old project code for previous analyses don't run anymore. Would Nix allow me to specify/run different R and R package versions for projects in different locations/folders?

dm319··on Vim Keybindings Everywhere – The Ultimate List
Yes, I came across a similar experience. My UHK keyboard has by default, movement mapped to ijkl. I remapped it to hjkl because I figured I'd find that easier, but it turns out there isn't a space in my brain for 'navigating just using hjkl and not the other vim keybindings'. It was easily solved by reverting it back to the default.
dm319··on Termux is an Android terminal emulator and Linux environment app
Ah thanks. Wish I'd seen this before I embarked on things! I muddled my way through doing things like:

nix-env -iA nixpkgs.rPackages.tidyr

This seemed to work fine for things like R and Vim and some dependencies, but didn't work so well for R packages which I think all needed to be compiled and installed from R.

I'm very pleased to have a working set up now, with neovim/nvimR/R/git etc. remarkably similar to my regular set up, so many thanks for these tips!

dm319··on Termux is an Android terminal emulator and Linux environment app
I love that someone here knows a work around for this! Thank you, giving it a try now. I keep hearing about Nix, but I feel like it is something I don't and won't fundamentally get the concept of. I put it in a box along with things like 'multiple dispatch' and 'immutable operating systems'.
dm319··on The curious side effects of medical transparency
Particularly so if you're trying to treat a patient with limited insight.
dm319··on Termux is an Android terminal emulator and Linux environment app
I loved using termux to run bits of my R code in it. With git and my text editor/IDE, it actually felt pretty good.

Sadly I can't seem to get R to work on it these days.

So I'm quite happy not being on platforms like this.

Gotta say I'm not especially impressed with my Google assistant on my pixel either. The hit rate makes it worthwhile only when I have to use it.

dm319··on One decade later, GNOME still sucks
I really floundered when Ubuntu 10.04 got to end of life. My personal issue with Gnome 3 was that the way I worked involved one workspace with lots of open PDFs.

Because they all looked similar on a thumbnail, I tended to use their filenames to identify them. The 2D workspace unfortunately shuffled them around as they moved between rows, and it preferred thumbnail over filename.

Basically I needed the 1D taskbar with filenames and that's what worked for me.

I floundered via Unity, Fedora, eventually settling on crunchbang for a while. I tried gnome fallback and flashback but they were deficient.

One day MATE appeared, and I have never appreciated a well-honed DE so much.
