Writing a novel around one scene I envisioned somewhere in the middle is a bitch...
Especially when it requires a vampire character. So many questions, so many contradicting answers...

Testing the chess thingie..
Waiting to get my arse served to me on a tablet...
Still not a chess player...

Your move [? for help]:
Wrote a small chess-over-gab client in bash, as a break from my (now daily) "toiling" at my editor's development.
And no, I don't play chess...
Re: @monolalia Thu 24 Nov 2022 16:23 UTC
What about linking your notes to the projects and not moving/copying into them?
I usually write "stuff" down, then tag it. It's either in my lab or in my notes.
People from Bell Labs often tell the story of the 'pipe orgy' happening after Ken Thompson finally gave in and implemented pipes, as imagined by McIlroy.
I guess spending a day extending my toy project with external macros day after I added support for them, comes pretty close.
Except it's not the Pantheon of Unix gods playing with awesome shit...
Adding custom keybindings to my editor took exactly *ba-dummm-tsss* 3 lines...
Added named buffers to my editor, so now I have a choice between pushing and popping the yanked lines from stack or using the session-persistent named buffers.
My day job is awesome, but there are days I seriously doubt my life choices...
"Learn, son, or you'll have to work at weird times..."
The subtle line diving the state "why tf can't I figure out why it isn't working" and "Oh, that's a minor bug, I'll fix it tomorrow" -- priceless.
Last night I could execute a statement defined outside of the main program, in it's profile file - it feel like I am slowly getting somewhere with the little project.
It made me think though - to make custom keyboard shortcuts possible I'll probably have to:
- move some code I wrote directly in the "keyboard handler" into small utility expressions;
- rewrite or extend the keyboard handler to use an assoc with keybindings;
- add more helpers to make programming of the extensions easier;
- ... and -- gods help me -- document it.
It looks as if my little project didn't move a bit, but after today's session I have:
- a reliably working scrolling
- faster display
- a quite solid list browser in Slope I can re-use (soon, hopefully) when writing a client for my chat.
Yay! The !@#$ing scrollin works now. I created also a keyhole into the interpreter (like "ex-mode" in vi, except it gives access to the interpreter beneath the editor.
40 years ago some sad fuck thought making Lisp accessible from his editor is a brilliant idea... Everybody knows what happened later :D
+31 lines added, 30 lines removed later scrolling works, finally (wonky, but stable).
Things like that make me thing: is it the reason Bill Joy stopped using `vi`, while Ken Thompson is still a fan of `ed`?
Because honestly, if you only programmed with ncurses -- you don't know shit :D
(Storing for later) Two African recipes from yesterday's feed:
Both can be done without meat.
Never underestimate readline-type libraries. One day you're mucking around with one editable line, the next day you're falling down the rabbit hole, thinking about the right way to add syntax highlighting to your text editor...
A normal person: How many IDs between 'aa' and 'zz'? 🤔.... 26 * 26 = 676
Me, the shell junkie 🧐:
$ echo {a..z}{a..z} | wc -w
676
"I'm too lazy, I'll rather write a program than do it by hand"
Exhibit A:
(list->string (map bytes->string (range 26 65))) "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
Setting my EDITOR environment variable to `xi` was probably the most brain-dead idea I had this week (let us hope it was).
As a consequence of the _obviously self-inflicted_ drama I am stumbling all the time ("if you wanted vi - why didn't you code it that way?"), but it certainly helps me lint the issues.
Like: I didn't notice how much I rely on range operations (hard to do anything "range" in a line-oriented editor without the concept of "global") or ability to read-in a block of text from an external file.
I didn't set a roadmap for the little project, but I think - if I keep using it, of course - the project will show me where I should go next.
Sometimes I think `nano` is not a text editor but a symptom of a rather specific, closed, and quite disagreeable mindset.
(not all nano users are incompetent wankers, but it certainly helps...)
Thinking about some low-cost (computationally speaking) HTML to annotated text conversion...
Somehow old school - cut the irrelevant parts off, strip html tags to their meanings (<h3 style="big"> becomes .h3, for example), break the remaining text on spaces, decide what to do with the markup, concatenate the words back into lines intertwined with markup, fold.
It could reduce all the fuss to something malleable and easily manageable through pipes. Gopher, Gemini, Spartan and shlogs, as text-based media, are much easier to handle, so I am already "there" - building my own "retrievers" and piping them through various filters.
HTML? Not so much yet, output from text-based browsers is okayish, but still incomplete (I'd like some formatting and functioning links, but the blanket here is definitely too short...)
Vertical systems' redundancy sucks.
It's maybe nice to test something in a lower tier before bringing it into production, but making a trivial update of one system in the production tier a "measurable risk", because its (theoretical) redundancy does other jobs is kind of meh.
Getting the scrolling and vertical cursor movement right is such a pain in...
Upgrade to tinylog.slo - "readline" support (thanks to Sloum's "line-edit" module).
No more retyping of lines (and I typo a lot...)
Kind of reduced tic-tac-toe to one regex: \(\([XO]\).\{0,3}\)\1\2
My little chat project reached 130 (server) + 70 (client) lines of Slope code.
It's going to be less, at least on the server side, after I move some of the "/utilities" into the separate bot/utility program...
I'll have to write some summary of development goals, as people who tested it kind of assume I'm going to replace the IRC.
I am not (what a surprise) - I simply want a chatroom I can spin up when working on some project, to move from the kind of working, but cumbersome email+gab communication to something more realtime...
Does a "slow internet" site like RTC need a realtime chat? I don't know, but now we have one...
It's amazing how easy(-ish, juggling with ANSI seqs almost killed me :D...) it was to write in Slope.
"Slope has net-listen now" -- well, and I have a chat server in ~100[1] lines of Slope code now...
[1] under 60 without '/' functions (they are not crucial for the functioning of the server)
Yay, Slope has net-listen now :)
The editor I "discovered" a few days ago - `sim` performs - against my expectations, quite well.
Especially when I have to make some small, localised changes in one or three files while I'm connected over ConnectBot from my phone.
The "all editing happens in the middle line" is really comfortable in a terminal constantly changing its geometry depending on the visibility of the soft-keyboard.
Unless I hack the code it's rather improbable it will replace `vim` or virtually any other editor I frequently use, but... But I am keeping it, I guess - for all the emergency INI file edits while I'm commuting.
Yesterday I've noticed that `recent++` reactions became a little sluggish ("a little" being going from ~400ms to +3 seconds).
NGL, it made me think about the future of the tool. What if the pubnix I am on grows? There's no caching, and traversals over more and more files *will* take more time.
Well, then the reboot came, and now we're back at <400ms. But I'll keep thinking about possible optimisations. So far I run it on 3 systems outside of my "$HOME's home pubnix" -- some with well over 500 users logged in all the time and generating content, and the "lag" is still acceptable. We will see.
My interaction with Gemini is 95-98% limited to two little scripts I wrote a while ago in a Scheme dialect. One is basically `cat gemini://url`, the other I use rn for "patching" my fresh tinylog entries between the header and my older ramblings.
I tried a few browsers (Linux, Windows, Android apps) and honestly - I don't care. None of them came even close to my ideas of aesthetic or ergonomy. And you know what? I cannot write a functional browser for 2020's web, but I pretty much can do this for Gemini. To get the content I want, where I want, and in exactly the form I want.
Lol, I didn't remember, but my tinylog reader is just this:
tl () {
gemini.slo gemini://tinylogs.gmi.bacardi55.io/ \
| sed -e 's!_\([^_]\+\)_!\x1b[4m\1\x1b[0m!g
s!\(\(gemini\|https*\)://[-~a-zA-Z0-9\.\/]\+\)!\x1b[32;4m\1\x1b[0m!
s/^##[^#].*$/\x1b[33m&\x1b[0m/g'
}
Discovered a whole bunch of modal editors: neatvi, nextvi (apparently improvement on neatvi), and sim.
While the first two are simply rather lean clones of the original vi with some interesting additions like bi-directional entry (the author of `neatvi` is Persian, I guess) `sim` is where the gonzo zone begins...
I can't see (yet) the alleged Plan9 `sam` inspiration, but the idea of editing your text with the cursor line staying firmly in the middle of the screen, with the text moving up and down instead is quite nice. A little like writing on a typewriter. Or in `wordgrinder`.
For some reasons the default keybindings (defined suckless-style, in config.h) didn't include "^". A strange omission for a) an editor inspired by `vi`, that b) has StartLine function implemented already. One edit later it worked.

...instead of what they could or should understand?”

The problem aren't people who use `nano` or any other "small" editor, but the people who aren't using enough of it.
[rant]Doesn't make any difference when you're changing 1 to 0 in a short INI file, but wastes your and your co-workers' time when you're applying the same approach when making critical changes to multiple unformatted XML files all over your filesystem..[/rant]
Watching "Oral History of Guido van Rossum" on YT and reading about the "ABC" language.
Lots of recycling when it comes to syntax, ngl.
But GvD doesn't make a secret out of it.
Reading the original Bill Joy's "screen editing with vi" manual.
One thing learnt - <Esc> and <Enter> are equivalent after "ex/:" commands (only the original vi honours it, though)
One thing re-learnt (`` and '' can be used to jump back after a cursor moving operation - I used it a lot... and then I stopped - I blame vim's `v`)
Considering rewriting the "displaying" parts as wrappers for `.g`lobal.
Added `.s`ubstitute and it was quite fun. The bemacs' command language is quite verbose already:
what would be simply a `,s/Foo/Bar/g` in other editors becomes `.s Foo Bar g` in bemacs, but `1,10s/Foo/Bar/g` is `.s Foo Bar g 1 10`...
Well, that's actually not much longer -- maybe the order of parameters is what throws me off.
Anyway, at some point I might write a simple wrapper around the functions - pretty much nullifying the "editing without leaving the shell" effect.
Extended `.a`ppend and `.i`nsert commands in bemacs.sh to mimic their `ed` equivalents.
Is writing a text editor in Bash a sign of spiralling down into madness?
By 'an editor in Bash' I don't mean a program written in bash and stored in an .sh file with a proper shebang line.
It's literally a set of macros modifying a file in a buffer straight from the shell prompt's level.
I added search `.q`(uery) today, and the nice side effect was Bash match operator actually understanding regexes.
And a pipe-out/shell-out function `.!` -- at this stage I am actually able to write and run programs without actually storing them anywhere on the filesystem.
Can it be usable? Idk. On a read-only $HOME, perhaps. The more functionality I put into it, the more closely it resembles Smalltalk VMs (of the past? Does anyone still use ST?)
Chicken and egg problem: I want to install a newer version of an interpreter I use on my local system, but compiling a new binary requires some preprocessing done in the language itself.
The version installed on the remote system is too old and the translation breaks. I cannot upload a newer version, because I am on Linux and the remote system is OpenBSD...
Well... Ended up mounting the remote install dir via sshfs, starting the compilation on Linux, switching to BSD, removing object and binary files and restarting. Compiler happily used the intermediate files generated on my local system, voila - a fresh version...
I fucking love "Lunix"
The meek will inherit the Earth, but the lazy will rule the IT.
My work-related pet peeves: people using characters outside of the ASCII subset on old systems.
It's 2022 and you may take UTF-8 for granted, buttercup, but we're working with dozens of early 2000's machines here...
I think being nostalgic in IT comes easier when you weren't actually working with the old crap.
Well formatted and reasonably well documented `ed(1)` subset written in Snobol4?
Why not? So far it took 82 lines of code (including command description and a shebang)...
Writing a small script for every little, mundane thing I might want to do again some time.
Side note: really getting into line-oriented editors rn. It's not that they're new, to me, or in general, but the nearly distraction-free workflow when writing stuff in `ed`, `sam`, `ex`, `qed` or even `edlin` is a real therapy after workweek spent on shuffling information in dozens of windows and panes.
My work-related pet peeves: people who refuse to follow ANY, no matter how basic, but *consistent* formatting when preparing documentation. Also - the ones who say: "I am a system administrator, not an artist" (the fuck, that's why you should keep documentation consistent and easily readable).
My work-related pet peeves: people who use lists created weeks ago to handle dynamically changing processes.
My work-related pet peeves: people who don't use editor's own copy/paste function but rely completely on mouse selection. People who insist on using context menu to do copy/paste.
My work-related pet peeves: people who scroll through shell history instead of using the reverse search function.
My work-related pet peeves: people using nano or notepad for serious text editing.
It seems when it comes to software and operating systems there's a wide gap between what I'd consider a "household item" and a "tool".
My customisations are restricted to "household item" programs ($HOME, get it? :irritating_chuckle:) -- I modify my local/at-home configuration, my .vimrc has chapters and my .bashrc uses a big-ass library of small scripts. I compile my editors from source, I write utility scripts in all shades of exotic scripting languages.
Then, there are tools. Things I use everywhere, things that I expect to work (more or less) the same way everywhere. So, unless there's `exa` installed by default on the oldest Solaris I have to manage -- tough luck. Besides, the "added functionality" is as useful as sequins on jeans...

What about "Nothi me non tere"?
(My sole contact with Latin are mariachi bands :D)
If life gives you lemons -- that's a nicer alternative to scurvy...
I read Brian Kernighan's UNIX memoir a while ago. I guess that's how a successful life looks like -- you're so busy writing about awesome people you worked with that in the end your "memoir" is barely about yourself.
I am especially glad BWK wrote a lot about AWK and Doug McIlroy -- I am pretty sure UNIX wouldn't be such a great system without those two. A small language that could, and a largely unsung genius who invented the Unix pipeline.
@deerbard: check your _local_ vim: `vim --version |grep xterm_clip`... if it says something like '+xterm_clipboard' the "+y will work... If not (or if you're on a remote system) -- you'll have to use your mouse (or the copy/paste functionality of your screen/tmux/dvtm)
`vim` on the console can only use its own clipboard (copy-paste buffer. Actually something like 28 of them. Named.)
If you are using it in an xterm (or whatever people use these days) window, and you want to use your mouse to copy stuff from/into Vim: press and hold Shift while selecting. Then paste it elsewhere, as usual.
You might use the '+' buffer in Gvim (that's mapped to system clipboard IIRC) --> "+y
Reading an old manual file for a Lisp Machine (dated June 8th, 1984) . Just stumbled upon `with-open-file` working exactly the way the the similar statement works in Python.

How to water your plant "without" a Gemini client:

`slope` can be compiled now -- ~sloum wrote a nice compiler/linker - it resembles slightly the way the old DOS BASIC compiler worked - by embedding the source and the interpreter in a single executable file.
It might not be the most storage-efficient way, but giving someone a file/link to the file is much easiert than asking them to install all dependencies.
I'm kind of having a Hannibal Smith moment right now: "I love it when a plan comes together"
Except - it never was a "plan". It started with a shocking (not anymore) discovery, that the system I'm on doesn't have the `bc` calculator.
After looking around and finding some, not so suitable, tools a normal person would just find the source package, compile bc and move on.
Well, not me, obviously - I decided to write an RPN calculator in bash... Then the way assemblylanguage routines should handle the stack made me rework the stack of my calc.
Then I wanted to see it... Then it wasn't a calculator anymore -- it turned into a set of command-line macros that allowed me basically write and run ASM programs in Bash ("in", as in mixing bash and assembly commands and sharing the screen and variables.
And now I am just translating the lines into Javascript to make it less 1970's-chic.

1. You can have more than one SSH key. Just give it a different name than id_rsa*
2. As they are all by default located in your ~/.ssh directory you can simply backup them as any other file on the system.
3. Restoring them is easy too -- just copy them back into ~/.ssh.
4. Guestbook for the capsule would require a CGI script, but it's doable.
Honestly, there's a separate circle in hell for people who defined keyboard shortcuts in `nano`

At the moment I'm just trying to water my plant on astrobotany (ngl it would wilt without @deerbard's help, thanks, buddy!) and keep the software I wrote and made public running and patched.
Writing anything new? No, not yet.

You can consider me the last person who wouldn't like to try something new, but `fish` is an eleven-foot pole case for me (that's a pole I keep for touching things I wouldn't touch with a ten-foot pole).
I tried to use it, years ago, and I am still slightly appaled.

No, it's *years* since I played chess last time. I kind of lost interest, I guess having to "think ahead" at work all the time doesn't help. And -- I should actually begin with that -- I never was a good player.

I guess it's time to stop calling chess a 'strategy game'. It's tactics. You win a battle in chess, not a war. And I guess all the generals that declared any war in the last century a win -- played chess. If chess was a war game the playing should continue after the 'king is defeated' (checkmate). The whites won? Great. Now the whites help blacks rebuild their society. How is the chessboard divided now? Is is still 32 fields for each side? Can a kingless bunch of rooks, lead by a bishop, still try to assasinate the white king?🤔
I can see some variations of the game:
- "German chess" - the losing side divides their side of the board in two, has a small checkers minigame;
- "Polish chess" - after the opening a third side appears on the board and works together with blacks or whites. The losing side never accepts the 'checkmate', at once a king reappears in the different part of the chessboard...;
- "Russian chess" - for every rook killed two new appear, no piece is allowed to retreat;
- "Japanese chess" - there's no particular strategy, all pieces move at once, sacrificing a rook isn't actually optional;
- ... and so on, and so on...

I might have patched the problem 'lace' has with incorrectly formatted dates (or at least I found a good place to do so).
People 'sent' almost 500 messages via gab in the course of the last two weeks. Seeing how much 'life' everybody gets in spite of if -- maybe it's not 'social network' that ruins your lives, but the notifications? ;) [I doubt anyone expects an instant reply in 'gab'...]
Slope has the 'file-append-to', I added a few lines of code to have 'file-read-from' -- for symmetry. To do - 'file-prepend-to' and probably 'file-prepend-at-tag' or something like that for tinylog type files (where all the new content goes between the header and the latest entry)

I had a rather lengthy exchange about the rather inadequate support for Unicode characters on Linux console. What works perfectly in a 'text' terminal emulator gets mangled and partially replaced with white squares on the console. Even in FB mode, with the proper encoding and font loaded -- there's still lots of _actually not so weird shit_ that just can't be displayed properly. Okay, meanwhile, Russian or Polish people are not fucked anyymore when trying to read or write on the console. But I pity you if you're trying to write math formulas. I guess only 2² gets displayed properly, all the rest is simply a square.
"I hope it will get better..." said my interlocutor. I'm thinking and thinking and I just cannot see it. Everybody drifted into the world of graphical interfaces, plus the text console does what it was intended to do -- gives you access to the system on a very close, very basic level. Will we ever see emojis in kernel messages? Well, I hope not, because they won't be properly displayed...
Ever noticed how you grow when something you need isn't available? I guess lack of something is a good impulse to kick our butts out off the consumption circle. And every temporary need creates a permanent value.

Woke up to a new time/data functions specification ;-) Format of the timestamp changed slightly, hopefully it doesn't break anything...

Being "thrown into deep water" at the very beginning of a new job has its advantages.

Keeps you on your toes. If I only had so much fun learning back then, at school ;)
Changed the date format in tinylog.slo. Let's see how it works. Thanks @deerbard for pointing it out (I didn't know I'm under surveillance now ;-) )...
In case someone needs to fold text after 60th column ;-) ->
(for-each (lambda (line) (display line)(newline)) (regex-find ".\{60}[^ ]* *|.*$" Long))
<- Yes. That's pretty much all. 'Long' is a variable holding the long text line you want to fold...
Gemini client in six-ish lines of code? nice :) #slope
Yessss! It definitely did!
Will the other entry land where I expected it to appear?
So, it happened. I didn't expect the first slope script I _might_ use regularly would be a tinylog updater. The gab client (gaby) is already at a quite advanced development stage (minus a necessary rewrite to replace my /etc/passwd hack with a much more standard and efficient fileglob), but wrapping a oneliner I already had in some file updating logic wasn't particularly complex. So here we are. An update from inside a slope script...
After years of avoiding?/neglecting?/not finding use for? Scheme I took a deep dive into a "locally developed" Scheme's dialect - 'slope'. It's really refreshing to take a different approach to solving problems. I am actually amazed how deep has the basic syntax of the language embossed itself in my mind. I must admit -- every time I start a new project in Python -- I have a moment of hesitation -- "how exactly am I going to make it run?". Nothing like that with Scheme. For example - I've noticed slope has a for-each expression, and (I tested it at some point) it works exactly as your intuition tells you, but doing a "loop" using recursion felt so natural. Why is it so? And why am I "at home" with Scheme, but somehow cannot stand Lisp? Questions ;)
Slope is a 'for fun' project. You didn't believe the world needs another language? Another interpreted language? Another interpreted language with lots of parens? Good. That would be a weird assumption. Sloum writes it for fun, because he can. And, kind of as a side effect -- a working, slick and fast tool was created. I did some timing, comparing a standard program running here (written in Python) with my less-than-masterfully crafted bootleg version of it.
$ time ./gab.slo -c test >/dev/null >>> real 0m0.012s|user 0m0.001s|sys 0m0.011s $ time gab -c test > /dev/null >>> real 0m0.066s|user 0m0.054s|sys 0m0.010s
Not bad for a 'toy' language, huh?
I talked with a stranger. Why do people hesitate so much? Postpone stuff indefinitely. Don't call, don't text. Don't outline that story or essay, don't fill the gaps. Don't learn that song, don't lookup that information. When did everybody become so apathetic?

Harvested my first astrobotany plant. Farewell, Abigail! Hello, Abigail. Now growing at 1.2x speed.
I kind of love-hate the simplicity of Plan9 editors. From one point of view they're strictly following the tenets of Unix - "one job, but well done". An editor isn't a mail client, web browser, file manager... They're not syntax highlighter either... They're heavily depending on mouse. Or mouse chordings, combined with keyboad operations. They probably work great with mouse held in right hand (what I, as a lefty, don't do).
Still prefer the "impure" versions:
A great set of patches bringing acme into XXI century. A must have in my opinion.
[1]It looks great and I would love to use it, but for some reasons it refuses to react to my mouse-clicks.
Started a new project:
A personal assistant for the RTC shell
I must admit, some pieces of code I (re-)write make me proud, even if it's basically just snipping on the existing code.

Added -t (user template) to poll. Now everyone can create their own polls/questionnaires.
Freshly created linkulator files of a new user caused a false positive, because linkulator change detection used simple mtime check. It's fixed now. Because the script has to read the last line of the linkulator.data file the timing slightly increased (~260-270ish now).
Changed the checking method for all 'folder based' services: recent.py dives (one level so far) into them and returns mtime of the newest file (was the folder itself before).
That was quick, approximately 30 minutes from a vague idea to implementation. And it's simple - just a text file with an obvious markup, extendable and completely under control of the user (as it should be on RTC).
$ poll -l editor What editors do you use? geek4hire Programmer, looking for project os What's your primary operating system? sodapop Pepsi or Coke?
So far only a couple of polls, and not-yet-decentralised (I'm working on it), but already usable. Due to the methodology behind it (files in users' HOMEs) not really a democracy tool (voting is far from anonymous), but I hope it'll find some use here. Or not...

A weirdo as myself cannot just do the stuff in awk(1) and move on...
Both oneliners:
+ filter out the "comment lines" beginning with "##"
+ create an entry for every first word of remaining lines in an associative array/hash
+ output a list of unique usernames
tmp $ time awk '!/^##/{a[$1]++}END{for(u in a){print u}}' online.log | sort > online.a
