@mcc dicts are a relatively recent addition, arrays were in Tcl from early on. A dict is a single value, which can be assigned to a variable, passed around etc.. An array is more like a collection of variables.
I tried to capture what's distinctive about Tcl in a blog post a while back - colin-macleod.blogspot.com/202

Tcl/Tk

Tcl is often used in science, mostly behind the scenes. Here's a very recent article in the journal 'software' by Arjen Markus and Lenore Mullin:

"Implementing Mathematics of Arrays in Modern Fortran: Efficiency and Efficacy"

mdpi.com/2674-113X/3/4/26

It used the Tcl package 'plotchart' to produce the graphs in the paper. This is the package: core.tcl-lang.org/tklib/doc/tr

MDPIImplementing Mathematics of Arrays in Modern Fortran: Efficiency and EfficacyMathematics of Arrays (MoA) concerns the formal description of algorithms working on arrays of data and their efficient and effective implementation in software and hardware. Since (multidimensional) arrays are one of the most important data structures in Fortran, as witnessed by their native support in its language and the numerous operations and functions that take arrays as inputs and outputs, it is natural to examine how Fortran can be used as an implementation language for MoA. This article presents the first results, both in terms of code and of performance, regarding this union. It may serve as a basis for further research, both with respect to the formal theory of MoA and to improving the practical implementation of array-based algorithms.

A pauta sobre easter eggs da #SegundaFicha cobre apenas jogos? Como um usuário #Linux da velha guarda, gostaria de resgatar o easter egg das antigas versões do Red Hat (incluindo o #Conectiva Red Hat Linux), que exibiam um chapéu giratório se uma determinada região do `timetool` (aplicativo para ajuste de data e hora) era clicada. Não achei captura de tela, então, precisei eu mesmo fazer uma (emulador PCem, distribuição Conectiva Red Hat Linux Marumbi).

🏷️ Etiquetas adicionais: #retrocomputing #redhat #fvwm #fvwm2 #anotherlevel #tcltk #emulacao #emulation

A captura de tela exibe, da esquerda para a direita, do topo para o rodapé: - duas barras de ferramentas do módulo FvwmButtons em tom cinza-escuro (o mesmo da janela-raiz, como tecnicamente chamamos o "fundo da tela" no X Window System) com ícones coloridos, lado a lado, sendo a primeira barra voltada a utilitários de sistema e a segunda a operações de manipulação de janelas. - uma janela do nxterm exibindo a saída dos comandos `uname -a`, `cat /proc/cpuinfo` e `free -m`, na qual pode ser evidenciada a versão 2.0.34 do núcleo, compilada em 25/06/1998, num computador baseado na arquitetura x86 com processador 486 DX-4 e cerca de 30 megabytes de memória RAM, dos quais 9 MB estavam em uso. - uma janela do control-panel exibindo 5 ícones, entre os quais, o ícone do `timetool`, baseado numa agenda com o número 1 na página esquerda e o número 2 na página direita, com um relógio analógico de bordas quadradas. - um terminal com o usuário da raiz do sistema (root) autenticado e executando o comando `control-panel`, com fundo branco, aberto pelo primeiro ícone da primeira barra de ferramentas. - a janela do `timetool`, com o título "Time Machine", exibindo uma cartola vermelha giratória após um clique no indicador "PM", em alusão ao nome Red Hat, que significa "chapéu vermelho" em tradução literal para o português.

Tcl/Tk 9.0 Release Announcement - tcl-lang.org/software/tcltk/9.
The first major release in 27 years. 64-bit internal structures, so data can be huge. Full unicode with all the funky new emojis. Zip filesystems, etc., etc.

There's lots of new stuff, and some old cruft has been dumped, so some programs may need a few updates, but there's still a high level of compatibility. The page above links to release notes with details of what's in and what's out.

@mlnn I had a similar problem a while back (not with Teams but with a company-imposed screensaver that would mess up the screen-switching setup I was using when it kicked in). Since I use Tcl/Tk I was able to prevent this with a one-liner in wish:

while 1 { tk inactive reset; after 60000 }

See docs at tcl-lang.org/man/tcl/TkCmd/tk. .
I imagine you could do the same thing from Python via Tkinter.

What's the best logo for Tcl/Tk 9.0, which will be released soon? Please select one, or suggest a better option as a followup. Polls don't allow images, so the images are in the post which this is a followup to.

@konstantin Others have recommended Tk - tkdocs.com/ - personally I would use Tcl/Tk directly, not via Python. It's still being developed but backward compatibility is taken very seriously so 20-year-old programs still work fine or with minor adjustments.

Tcl/Tk runs natively on windows, macos, linux and most other unix varieties and there is an android port. For web delivery, take a look at CloudTk - you can see some examples at wiki.tcl-lang.org/page/Showcas .
