In a much simpler case, it seems to work:

\setuphead[section]
[style=\ss\tfa, after={\hrule\blank[samepage,big]}]
%~ [style=\ss\tfa, after={\hrule\blank[big]}]

\setuphead[subsection]
[style=\ss, after={\hrule\blank[samepage,medium]}]
%~ [style=\ss, after={\hrule\blank[medium]}]

\starttext
\dorecurse{10}{\section{Section}
\input knuth
\subsection{Subsection}
\input zapf}
\stoptext

Do you really need headings to be inside framed texts?

A good idea but it can be improved.

\definevspace[sectionrule][3mm]

\setuphead
  [section]
  [   width=0.8\textwidth,
   commandafter={\vspace[sectionrule]\hrule},
 before={\blank[0.5cm]},
  after={\blank[1cm]}]

\starttext

\section{\input ward }

\subject{\input ward }

\stoptext

Hi,

I am trying to typeset some strings in {\tt ...}, but they turn out to be 
pretty wide. So, I would like to compress those bits of text a little. Any 
hints on how I could do that locally, that is without adjusting the entire font.


\starttext
   \definecharacterkerning[tight][factor=-.5]

   test {\tt \setcharacterkerning[tight]tight} test

\stoptext

(Btw, there is a narrow monospaced lm font)


I implemented it by redefining \tt:
  \definecharacterkerning[tight][factor=-.075]
  \let\oldtt=\tt
  \def\tt{\setcharacterkerning[tight]\oldtt}

However, I find this a bit of a kludge. But opinions may differ, of course.
Can this be done in a more general way? For example by setting some font 
feature?


no, becasue it is independent of font features (and also less efficient 
that using a narrow tt font)

Re: [NTG-context] Buffered metapost function freezes random numbers

For educational purposes I try to simulate a ammeter for reading practice.
I would like create six or more ammeter with different readings, but i'm
not able to do that because metapost create the same random number every

How can I fix that?

Sorry, I know, but I didn’t know to reproduce the situation.

look likes it solves all the problems! I really have no idea of what’s going on 
here. Luckily this mailing list is super friendly.
Manuals are cool, but I always miss the big picture that would allow me to 
generalise over a problem!


Thanks

Best
