[gentoo-user] convert - color picker
I'm trying to convert color on a PDF file but it works partially. convert -density 300 document.pdf -fuzz 10% -channel rgba -fill none -opaque "#dbdbdb" -opaque "#b8b8b8" daily_appointment.pdf It converts only one color but I have a hard time to selecting grey color to white. I've tried "color picker" in GIMP, it doesn't work. -- Thelma

Evince is not masked in the gentoo repo, but the 44.1 version is keyworded with the ~amd64 keyword.

What if qtwebengine's (many) dependencies also need to be updated first? I think trying to outsmart the dependency graphing in portage is inviting frustration.
[gentoo-user] Question about gentoo accessibility.
Good afternoon all, This question might be better sooted for the accessibility list, but seeing that I don't seem to be getting help there I thought I would bring it up here. First off, I am an orca user in the gui, but use espeakup in or fenrir in the concel. I find that booting the officael iso, there is no easy way to boot up with speech. For example, in debian, at the boot prompt, pressing S will bring up the installer with speech and you can follow the prompts in the text installer which uses espeakup. Could something simlar be done for gentoo? My work around has been to use another linux distro iso. I.E ubuntu to do the install following the wiki, but seening there is no way to get speech after, that is whare I fall short. The other problem is that if trying to install accessibility packages like orca, there seems to be alot of problems with conflicks with flags and dependencies. For example, when installikng orca, it complans that espeak and espeak-ng can not be installed at the same time. What is strange is that espeak is not even installed at this point. Installing espeak-ng installs without a problem. Perhaps this is a bug that perhaps is unreported. Perhaps an accessibility profile could be created for this. Thanks and hope that this is something that can be looked at. The wiki doesn't have much in the way of accessibility in particular installing. Thanks again. Matthew

[gentoo-user] Load average revisited
Afternoon all, It seems that portage's self-protection from overload is incomplete - or so I've been led to believe by some pretty odd goings-on. Injudicious fiddling with -j, --jobs and --load-average can easily cause miscompilation of packages without causing an OOM or any other sign of problems. For some time, I had those values set to take advantage of the 24 threads and 64GB of RAM in this machine (not to mention 8 + 50GB swap, little of which appears ever to be used), resulting in the load average rising into three digits at times - over 200, even. But no sign of difficulty was shown and all appeared to have gone to plan. Until I ran the system, when odd errors would show. One example I remember is Firefox having a bizarre colour scheme (the window frame, not the page display) and missing the three upper-right buttons. That wasn't corrected by recompiling Firefox, so I assume the problem was lower down. I think I have some safe values now (time will tell), but it's worrying that compilation errors can go undetected. Of course I don't know where to start looking for the problem; I just hope someone else does. Meanwhile, is it possible to set things up so that, say, qtwebengine is never compiled at the same time as anything else? I don't want to rely on my noticing and intervening, and besides, it isn't always possible just to --exclude it. -- Regards, Peter.
