This text is a mess… just a starting brainstorm… it needs some time… be patient… please 🕉mmmmmm with me…

2 Some dates

2.1 20200214

2.1.1 New in irc.tilde.chat

more or less stealthy starting to acclimatise in irc.tilde.chat.

2.2 20200223

2.2.1 New at tilde.institute

login yeti
ssh key yeti@kumari
ssh key yeti@cubietruck1

2.2.2 screen autostart @reboot

see crontab and ~/.screenrc.cron-autostart

crontab -l | fgrep screen 
@reboot		./bin/screen -c ~/.screenrc.cron-autostart -O -U -dmS `hostname`

I do it in a similar way @home on lots of systems but on tilde.institute the reboot still needs a test… ;-)

2.2.3 tilde IRC channels

joined tilde IRC channels as seen in default ~/.weechat/irc.conf with weechat@home

2.2.4 ~/.kshrc ^= PS1   kshrc tramp

	PS1="`whoami`@`hostname` \$ "

(\u@$HOST:$LYN)\w\$ ' is just classic ksh stuff.

\[\ek(\u@$HOST:$LYN)\w\$ _\e\134\] sets screen's buffer (window?) title to look like the current shell prompt.

N.b.: \\ needed to be transliterated to \134.

Then screen's buffer (window?) (type: ctrl-a ") looks like follows (empty lines at the end omitted):

Num Name                                                                  Flags

An other example from @home:

2.6.1 Nah! I'm not an artist! (I)   layout org

Chiselled a bit to kind of give this org file a readable layout and colouring.

More in Nah! I'm not an artist! (II).

2.6.2 Read a bit…

2.7 20200228

2.7.1 pad.tildeverse.org

Noticed. Maybe it'll be of use somewhen but generally I prefer doing my stuff in an XTerm…

2.7.2 pocket-tilde

https://tildegit.org/Dataforge/pocket-tilde A private, go anywhere pocket tilde running on a Raspberry Pi Zero W! Host a tilde party, or use it for other interesting purposes

… might overlap with my ideas of lots of connected (meshed?) mini nixens (see tilde2tilde). I'll keep an eye on pocket-tilde.

2.7.3 tilde2tilde, t2t

In a different text I'm fermenting some ideas for a network of tildes. Central focus shall be communication in this community and who prefers it shall be able to run a t2t node only reachable in I2P, tor's onion space or other transports. Communication with the normal internet shall be optional.

The idea to call it tilde2tilde or short t2t is new today.

2.9.1 TildeNet ( aka ~Net)

2.9.2 Plan9 and/or 9Front Tilde?

An interesting OS, an unbearable UI.

Maybe some Plan9 and 9Front tildes would be the right place to collecively moarn this contrast?

Or do they already exist?

The tildeverse surprises me nearly every day with already existing stuff.

2.12.1 New Pi test run

Works! \o/

Today no time for more. :-(

This one (Pi1-5) will join "the house of RasPIan" with the other newcomer (Pi1-4) still wating for the final OS install.

Their job is keeping me in touch with RasPIan on ARMEL and occasionally doing some tasks where low power is more important than a big oomph like (outdoor) distance tests with some transceivers (HC-12, LoRa, …) as soon as the weather is nicer again.

2.13 20200305

2.13.1 RasPIan-ised pi1-4 and pi1-5

Both got 2020-02-13-raspbian-buster-lite.

Some colours don't fit this scheme and probably never will. Like red and green for TODO and DONE and the red background FIXME block.

The colours probably will change again, so here a snapshot:

2.19 20200311 - Fukushima Day

2.19.1 ⌛ …thinking in progress… (I)   org wiki

For my stuff (in most cases notes about programming languages) currently done in nearly 100% plain org/babel a more networked representation or navigaion would be nice but I fear losing the org/babel features when switching to a classic wiki.

Lookig at org-brain the lack of exports repells me.

Should I switch from plain org/babel to org-wiki?

I still need more input to decide this.

Maybe I can do more with plain org/babel macros like turning a list of targets (e.g. properties⟶related) into a navigation line below a section heading? Diving deeper in plain org/babel sure will not be lost time.

🕉mmmmmm…

2.19.2 DATA URI in org/babel (I)   org

2.20.1 The Joy Of Ebay?

Ordered a flux pen weeks ago. Seller and shop claimed to be in Paris. Paris to Germany would be fast, I thought. The pen did not arive within the claimed time, so I got a refund. A week later the pen arives. Coming from mainland China!

If he'd been honest about the long distance, I'd have bought it nearer to home.

2.22.1 Pi Day … aaaaaand … ???

Whats new in the Pi universe this Pi day?
What do I miss?
I dont see new stuff or anounces.

2.22.3 The next Pi1-B+ arrived

This Pi1-B+ was replaced by a Pi4 somewhere else and so was looking for a new home, tasks and friends.

Here it shall get a case with a 480x320 touchscreen. I hope, they'll like each other.

If halfway useable for that task, they shall help playing with various transceivers.

I thought, 700MHz will be enough for something mobile with a small display, while more uuumph won't help there and just would drain the battery faster.

It'll get it's welcome party tomorrow…

2.23 20200315

Continuation from Nah! I'm not an artist! (II).

I removed font-variant:small-caps from headings. Maybe I'll somewhen ditch using different sizes too.

The colours stay unchanged for now but I'm starting to question the current set of colours because the darker tones of this amber look a bit brownish. Maybe plain greyscale would be less distracting?

2.26.1 Welcome Pi1-a

So far my Pis just are used to follow some OSes. They are numbered pi{1..3}-{0..$X} where the 1st component is the Pi's board type and the 2nd component kind of codes the OS.

Two Pis per arch and OS. They are kind of software lab guinea pigs.

Name OS Comment(s)
pi{1,2,3}-{0,1} Devuan 1=1B+, 3=3B
pi{1,2,3}-{2,3} Debian 1=1B+, 3=3B+
pi{1,2}-{4,5} Raspbian 1=1B+

The Pi1 newcomer shall be used for hardware tinkering istead of feeding my OS curiousity and that doesn't fit the scheme above. I decided to name it pi1-a for now. Maybe I'll get a better idea later.

pi1-a got Raspbian/Buster today, will get a 480x320 touchscreen later, and one of its 1st jobs will be help with experimenting with transceivers.

2.27.1 eshell alias for rmail.el?   emacs eshell rmail

Welcome to the Emacs shell

~ $ which rmail
rmail is an interactive autoloaded compiled Lisp function in ‘rmail.el’.
~ $ rmail
usage: rmail [-T] [-D domain] user ...

Looks like despite rmail.el exists OpenBSD's rmail is preferred.

~ $ (rmail)

That way rmail.el launches.

First I thought I'd need an alias for rshell but I think I'll delay that until I made up my mind which of the MUAs in Emacs I'll use for longer.

2.28 20200320

2.28.1 #+OPTIONS: ...   org

  • num:nil

    Setting this looks better with headings that already look like numbers or dates. But not all headings do. So I removed it again.

    I'll stop thinking about this until I made up my mind about switching to org-wiki or org-brain and that decission sure still will take some time.

  • html-postamble:nil

    … may stay to get rid of the footer.

2.29.1 Updated org & installed org-brain   org brain

The current org-brain doesn't run on org-9.1.9, so I added ("org" . "https://orgmode.org/elpa/") to get a newer org-20200316 and org-brain-20200319.949.

Curiousity kills the cat?

I need to get an idea how to use this. Means: How to organise my stuff and when to use different brains for different topics and how to export stuff. Maybe glueing some brain files together via include directives would make a useful way to get a linear text from a bag of notes?

Some hours later…

Ok, still mostly needing to write linear texts about one topic I should explore plain Orgmode more before switching. Playing with Org-brain already may be a good idea but converting my current oldstyle linear texts to Org-brain should definitely wait a while.

2.30 20200322

Added to ~/.emacs:

See https://www.emacswiki.org/emacs/SaveHist.

2.30.3 Back to org-9.1.9?   org

The newer org (starting with 9.2) kills e.g. the structure template expansion.

The cure: Enabling tempo in org-modules reactivates it.

{
        const char hw[] = "Hello, World!\n";
        write(1, hw, sizeof hw);
        return 0;
}
$ make -B
clang -emit-llvm helloworld.c -c -o helloworld
chmod +x helloworld
./helloworld
Hello, World!
$ █

Thanks to binfmt_misc llvm bytecode(?) is directly executable on Debian10.

The same binary transferred to OpenBSD-6.5:

$ ls -l helloworld

Should I read all the changelogs and release notes since 2.5 now?

Ok! Took a jet for the fly over.

🕉mmmmmmmmm… o;-)

2.34.3 Devuan3 Netinstall / Devuan4   devuan

I test installed devuan3 via its beta netinstall images on an amd64 VM and an i386 VM and then instantly upgraded the result to devuan4.

Just for throwing an eye on the installer's and devuan4's progress.

Win-Win!

2.34.4 DATA URI in org/babel (II)   org

Continuation of DATA URI in org/babel (I).

@@html:<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot" height="32" width="100%"/>@@

Yields:

Red dot

I had no luck with relative units like 2ex or 20pt. Maybe wrapping it in a div of a given size is the way to pass the outer dimensions by using percentages of them in img.

2.34.5 2019-nCoV Data (III)   2019ncov

Continuation from 2019-nCoV Data (II).

Live(?) data for Germany:

2.35.1 Document Navigation   layout org

Added more "Continuation of …" and "More in …" lines/links.

These should be macros but as long as swithing to org-brain or org-wiki still is on my wishlist, I'll add those links manually. If not switching to org-brain or org-wiki I'll chisel some macros.

2.35.2 The Covid Curve (II)   2019ncov

Automagically add all these updates to a summary table in an own section or node using orgmode magic.

2.36.2 Nah! I'm not an artist! (IV)   colours org

Continuation from Nah! I'm not an artist! (III).

Ok. Amber CRTs are a nice nostalgy but I think mainly using a greyscale needs a chance too.

It's all in flux, so here again a snapshot:

2.36.3 Nah! I'm not an artist! (V)   colours org

Continuation from Nah! I'm not an artist! (IV).

Textcolour #eeeeee was a bit too bright. Using #cccccc now.

It's all in flux, so here again a snapshot:

2.37.1 Lazy today?

3 TODO somewhen… mayhaps…

3.1 find a layout with nice 72 CpL & 80 CpL coexistence   layout org

Find a layout with 72 CpL for text but 80 CpL for code like in ye olden days with text in pica, code in elite on 8" wide (A4) paper.

IIRC pica had 10 CpI making it nice on A4 with 4+4 or 8+0 chars (left/right) border still giving 72 CpL.

IIRC elite had 12 CpI, so 96 CpL on A4 width. Centered 80 CpL code boxes should fit nicely between 72 CpL lines in pica.

Maybe it is as simple as making normal text 120% of text for code.

Maybe it isn't really worth it. I need 80 CpL for code and typical hackers' eyes will be used to this width and will have no problems with 80 CpL for normal text. I've written lots of stuff in this all monospaced and all 80 CpL look and nobody complained.

3.2 play with tor and mapaddress   tor

not urgent

3.3 HC-12 and LoRa433 range tests   hc12 lora433

  • How far can they reach.
  • How much bandwidth will remain at which distance?
  • What protocol would make sense?
    • Pure serial?
      • Unencrypted probably is not a good idea.
    • SLIP?
    • PPP?
    • VPN?

3.4 dvisvgm - A fast DVI to SVG converter   org svg tex

Quoting https://dvisvgm.de:

The command-line utility dvisvgm is a tool for TEX/LaTEX users. It converts DVI, EPS, and PDF files to the XML-based vector graphics format SVG. In contrast to bitmap graphics, vector graphics are arbitrarily scalable without loss of quality. All modern web browsers support a large amount of the current SVG standard 1.1. Furthermore, SVG files can also be displayed with the Java-based Squiggle SVG browser which is part of the Apache Batik project, and the free vector graphics editor Inkscape.

I think I read rumours that newer Org releases support it.

3.5 more modifiers via add on keyboard?

Can an added keyboard be used to get more modifier keys? It would be easy even with an Attiny85!

3.6 net2o — reinventing the Internet   chat forth net

I need to try it.

3.7 Orgify Emacs Startup   org

(c'est la z) Using Emacs - 10 - org init files looks like a good start. \o/

3.8 Banana Pi R1

Got two of them. Installing Debian and Devuan failed. The install images ignore the keyboard. Maybe I'm expected to do it using the serial console? A test run with OpenWrt-18.06(.4?) succeeded but I want a Debian sibling or a BSD on them.

Retry later…
