Re: Connecting a Raspberry Pi Sense HAT with a ribbon cable

Dave P — Sat, 10 Aug 2019 09:27:23 -0000

rpi 4 and Sense hat.
I've (just) mounted a fan, then the sense hat.
Using a male - female 40 w ribbon, I'm connecting as you have (with a m-m) coupler adaptor. So far failing, the ribbon is not making with the pins, but same idea as yours.
Thanks.

Macro lens, close focus and wind? Ever use a stake and clips to keep a flower steady?

All the cameras I've used have been shadows Left, Highlights Right?

Re: GraalVM UTF-8 Validation

Dave P — Mon, 08 Oct 2018 05:09:08 -0000

Ant task
<target name="ck-utf-8" depends="xinclude">
<echo>Validate encoding</echo>
<property name="ckutf8" location="/data/installation/xslt/utf8/bin/validate.sh"/>
<exec executable="${ckutf8}" failonerror="true">
<arg value="${main_expanded}"/>
</exec>
</target>

requires shell to be named in validate script (validate.sh).
#!/bin/bash
Guessing bash most common shell script?
Works nicely, thank you

One of the bugbears of working across systems. XSLT baulks at bad characters (Saxon) but is mostly unhelpful at saying which characters are the problem. I'll give it a try Adam, thanks.

Re: 7 Tips for Doing Crystal Ball Refraction Photography

Dave P — Sat, 12 May 2018 02:31:44 -0000

Two points seem to come out.
1. The need for close focus (macro?)
2. How to hold the ball?
I'm looking at a small platform to sit on a tripod to hold the ball,
though I think a tripod will be needed for the camera too with the fine focus needed.

Where is focus? on the ball, or the image through the ball?

Thanks Xah. Now working
;; docbook section, dated id, marks up title
(defun dbs ( a b c)
" Insert docbook section, with date given as prompted value, mark up title"
(interactive
(let ((string (read-string "date: " )))
(list (region-beginning) (region-end) string)))
(goto-char (region-end))
(insert "</title>\n")
(goto-char (region-beginning))

Re: Emacs Lisp: Interactive Form

Trying to use interactive with region and prompted response?
How to access three values, and what args should be passed to the function please?
(defun dbs ( )
(interactive
(let ((string (read-string "date: " )))
(list (region-beginning) (region-end) string)))
(insert string)
)
is failing, wrong number of arguments?
Suggestions please Xah?

Simpler question. Is this good for producing (say) html with hand drawn graphics? Same app?
