Re: Arduino on Mageia linux

[Shlomo Solomon]

As I already wrote, it turned out to be a bad USB cable. I should have
checked that first. My bad.

Re: Arduino on Mageia linux

[borissh1983]

Hi , 

I had a similar issue when I checked the wrong board in the IDE (few years ago 
things may have changed). 

Unplug the device , close the IDE , plug it in again and : 

dmesg
ls /dev/serial/by-*

start the IDE again and make sure you choose the correct board.

I just did a series of tests, and it doesn't seem to be a big deal.

1] In debian, install package 'fontforge'.

2] Create folder ~/.fonts

3] Copy a font's file to your home folder (I chose
/usr/share/fonts/X11/Type1/DorianCLM-Book.*)

4] Follow the instructions at ref[1], but before saving, for the
purpose of the test, go to menu 'element > font info' and change the
name of the font in all fields to something new and unique and
original, like ''.

5] When saving the font per the instructions at ref[1], select your
~/.fonts folder, and for the purpose of the test, name the saved font
file ''.

6] From the command line 'fc-list ' should return the path to your
new font.

7] Open libreoffice and test the font.

8] What about running in batch mode? Whoa, Google tells me that
'fontforge' supports python scripting[2], and the "simple example"[2]
is none other than converting a Type1 PostScript font (a pfb/afm
combination) into a TrueType font! I didn't play with that.

Re: [LibreOffice 5.3/Ubuntu 17.04] Culmus Fonts not detected

[Dov Grobgeld]

It should be quite trivial to do the conversion with the open source
package FontForge. Note that converting Type1 fonts to otf is a lossless
conversion, as OpenType is a superset of Type1 and TrueType. Type1 and
TrueType store the font paths differently as Type1 uses Bézier curves,
wheras TrueType uses quadratic B-splines.

See:

It's not as bad as it sounds, only some of the fonts are only packaged
as Type1 (culmus-fancy is Type1 only) the rest either ships as
OpenType or TrueType.
There are also quite a few other Hebrew fonts out there part of the
different distros.

It seems to be a trivial conversion, I did it using the Adobe Font Dev
Kit but it should also be possible using fontmagic and other OSS
tools.
The fonts seem to work fine and look the same as they used to.
The conversion tool did give me some errors/warnings so I don't know
100% if they are OK.

Wow...
So I'm lucky that Fedora 25 which I use still uses LibreOffice 5.2.
Someone (TM) really needs to fix this issue, because I'm not aware of
any alternative quality Hebrew fonts on Linux...

What does it take to "convert" a Type 1 font into OpenType or TrueType?
Is it just a trivial format conversion issue, or something more
involved? Is something lost in this conversion - precision, ability to
edit, or anything else?

On https://bugs.documentfoundation.org/show_bug.cgi?id=104701
someone states (I have no idea if this statement is correct):
  " ... PS Type 1 font conversion is trivial, and most Adobe PS Type 1
was converted years ago and is distributed as TTF/OTF already."


Maxim, are you still on this list? It's been ages since I've been here
myself.
