The Nineteenth Byte

9:34 AM

Shared Letters in consecutive numbers Inspired by this puzzling question. It turns out that, in English, every pair of consecutive integers (e.g. 0,1, 1,2, etc.) shares at least one letter when spelled out (e.g. zErO, OnE (or NOught, ONe); One, twO, etc). Input Any two positive integers (all ...

@NewMainPosts This would be more interesting if you had to create an algorithm that outputs a password given a seed and your score is the number of bits of entropy

To the power of 1/your source length? Or something like that

Although I guess most solutions would be something like "".join(str(random.choice(0,1))for i in range(9e9)) or the equivalent

@James What happened to your user name‽

I changed it

But, but…

@Adám I had a similar feeling when I discovered this:)

@James I'll tell one of the mods that your user name is offensive! I'll Tell DJ… oh.

Random question: I'm having some lag issue with vim, and it still happens with .vimrc & .vim is removed, but does not happen with -u NONE. What should I do?

(ask on vi.se?)

@user202729 Do you have plugins? Does it lag always or after a specific key?

Reproduction: run vim -c ':call feedkeys("i1\<cr>2\<cr>3\<cr>4\<up>\<up>\<c-o>Vjj")', then press >.

Arch Linux.

Tried removing .vim folder.

The CPU isn't used. Just that the screen takes a long time to refresh.

4:33 PM

Does :xnoremap > give anything?

No.(also read through the whole output of xnoremap, none of them start with >)

(can you reproduce that?)

Well, I do have an xmap for >, but that shouldn't have any affect on why you're getting lag

The status line (3 lines >ed 1 time) is printed, but the rest of the screen is not refreshed.

Wait a second, I take it back

When I xunmap > I get the same thing, it takes a few seconds to update. Huh

@user202729 Is that the only thing that hangs? Idk why that problem happens in the first place, but I have this in my .vimrc and for some reason that prevents it:

xnoremap > >gv
xnoremap < <gv

Except that it doesn't do what normal > does.

4:41 PM

Ah fair. I find that behavior more useful, but you could do this instead:

xnoremap > ><c-l> does work, but feel like a hack.

xnoremap > ><C-l>
xnoremap < <<C-l>

On a side note, I've always used xnoremap but there's probably no good reason for it since I basically never use s mode

(but why does it work? Should the c-l be executed in insert mode? Because the original mode is (insert) visual mode)

I decided to use the gv option.

@James what plugins do you use?

Plug 'tpope/vim-abolish'
Plug 'tpope/vim-surround'
Plug 'tpope/vim-repeat'
Plug 'tpope/vim-endwise'
Plug 'tpope/vim-speeddating'
Plug 'mattn/gist-vim'
Plug 'mattn/webapi-vim'
Plug 'tommcdo/vim-exchange'

Lol, I have never ever used julia

4:49 PM

you got a plugin from @AlexA. and from @Doorknob?

I'm thinking about getting surround

Surround is one of my favorites of those.

@James maybe Julia used you

@flawr Yes, but I don't really use either haha

If I could only pick a few of those, I'd say abolish, surround, exchange, nerdtree, and colorschemes

OUCH that hotdog hurts my eyes

^ {is that a vim bug? Anyone want to report that?}

4:53 PM

You know what's weird? This is one of the few times that something works better when compatible is set

@James I don' think you explicitly need to have the word nerd in anything related to vim.

@James the exchange seems to be neat, but isn't there an easy way to do the same with default vim?

Ehh, kinda.

(I was actually also wondeirng why surround is not in the default vim.)

viwywviwpbviwp isn't exactly "easy"

Hello @Doorknob, we were just discussing 'KeyboardFire/hotdog.vim'

Yes we were in the middle of a civil and objective discussion about the design and use of this plugin of yours.
