And it's a standard autoconf macro, namely AC_PROG_CC that results in
the error and the stuff before that is also standard. And as no
autoreconf is called, autotools versions should not matter.

I use gcc 11.3.0 here as well, and have no problem. Check for the

/var/tmp/portage/dev-libs/libofx-0.10.7/temp/environment.

From my tests with a swapfile (which matches what I remember from real
FSen), I think '-T largefile' vs. default frees up around 1.6% of the
capacity, so for 9.1T it'd be around 150G which might be worthwhile
_iff_ you are sure about what kind of files will go on that FS.

FWIW, in a pinch if you run out of Inodes, you can create an image
file on that fs, taking just 1 Inode, format that image differently,
loop-mount it and put ton's of files inside the image. It'll eat a bit
of performance though.

And about the average filesize in a dir: Just find out the size (e.g.: 
 du -msx /foo
) and the number of used inodes (e.g.:
find /foo -xdev | wc -l
[1]) and then just divide:
summed_size_in_unit / number_of_files = avg_size_in_unit
for FSen, just divide used space by used inodes.

Also, if you're using ext2/3/4, there's the preset, i.e. if you're
rather sure about what kind of data is going to be on there, you
can tune it so that it reserves more or less place for metadata like
inodes, which can be another bit.

I made some experiments with a temp-repurposed swapfile of 2051M size:

Output of 'df -m':
1M-blocks  Used Available   Inodes   mke2fs-options used
201667  1847131072-j -t ext4
201667  1949131072-j -t ext4 -m 0
204867  18782048  -j -t ext4 -T largefile
204867  19812048  -j -t ext4 -T largefile -m 0

So, defaults uses about 1.7% of the space for metadata, and -T
largefile only about 0.15% of the space. Of course, there are rather
few inodes with '-T largefile'. But if you want to put basically only
some big videos on there, 2048 inodes seems a lot for a mere 2G of
space ;) This should scale linearly (in steps) for bigger devices and
can amount to quite some more space.

Anyway, see /etc/mke2fs.conf, 'man mke2fs' and 'man mke2fs.conf for
details.

I've done this in the past and got bitten by too few inodes, but you
can get around that for "inode-hogs" like news-spools etc. by using a
loop-filesystem with different parameters or a different fs. Just
beware: reiserfs on reiserfs is a recipie for desaster.

FWIW:

For one: why not filter the iptables messages into a seperate logfile?

E.g. for syslog-ng (you'll need to add the filter to other
filters/log, having them in the filters you can use those
more intuitively):


filter f_iptables   { facility(kern) and message("IN=") and message("OUT="); };
filter f_console{ ... and not filter(f_iptables); }
filter f_messages   { ... and not filter(f_iptables); };
filter f_warn   { ... and not filter(f_iptables); };
[..]
log { source(src); source(chroots); filter(f_messages); destination(messages); 
};

# Firewall (iptables) messages in one file:
destination firewall { file("/var/log/firewall" suppress(30)); };
log { source(src); source(chroots); filter(f_iptables); destination(firewall); 
};


You might be logging more specifically, so you could add more specific
filters. That's what those filters (and log-prefixes in iptables) are
for after all :)

Also add a matching logrotate entry:


/var/log/firewall {
delaycompress
missingok
notifempty
size +4096k
sharedscripts
postrotate
/etc/init.d/syslog-ng reload > /dev/null 2>&1 || true
endscript
}


or some such as /etc/logrotate.d/firewall (or however you name you
iptables-logfile.

And second, how about setting up a local dnsmasq to send all fb-crap
to NXDOMAIN on the DNS-level?

 dnsmasq.conf or e.g. /etc/dnsmasq.d/blocklist.conf [1] 
address=/fb.com/
address=/fb.me/
address=/facebook.net/
address=/facebook.de/
address=/facebook.fr/
address=/facebook.co.uk/
address=/facebook.com/
address=/fbcdn.net/
address=/instagram.com/
address=/instagram.de/
address=/whatsapp.de/
address=/whatsapp.com/
address=/whatsapp.net/


That has the effect that all (sub-)domains with those names give
NXDOMAIN, i.e. are non-existant. Compare to:

$ nslookup there.is.no.such.domain.invalid

Depending on what sites you visit, you might add more domains like
e.g. facebook.ca, facebook.mx, facebook.es or whatever fb-domains
sites that you visit include...

Just as ideas,
-dnh

[1] you'll need a matching conf-dir or conf-file directive, preferably
at the end of the main /etc/dnsmasq.conf then, I use:

conf-dir=/etc/dnsmasq.d,*.conf

which includes all *.conf files from /etc/dnsmasq.d/ (and ignores
other files there like *.conf~ or Makefile or whatnot, so you can
be creative and e.g. generate your blocklist from a simple list of
domains ;) E.g.:
 /etc/dnsmasq.d/Makefile
all: blocklist.conf
blocklist.conf: blocklist.conf.in
sort -u $< | sed 's@\(.*\)@address=/&/@' > $@

Check with 'eix dev-python/pyyaml' or 'equery uses dev-python/pyyaml'
for what python versions that module is actually installed for and
compare that with the default python3 version (check 'python3 --version')

You probably need to re-emerge dev-python/pyyaml if PYTHON_TARGETS has
changed. You probably have it installed just for one target (which is
not your current default python3).

I needs just to be recompiled, I think. With '-std=c++11' or later. 
Search for
'undefined reference to std::__cxx11::basic_'
(no quotes) on your least untrusted search engine, or better, if your
search-engine supports the 'site:' parameter, for 
'undefined reference to std::__cxx11::basic_ site:gentoo.org'

AFAIR, there were both at least one news item and tons of
mails/forum-posts about this issue with 'std::__cxx11::basic.*string'
stuff. It's that C++ ABI change for all that string related stuff. It
all basically boils down to just recompile all your C++ libs using
some form of (basic_)string (and all stuff depending on those) using
the new cxx11 ABI. ISTR that was rather well communicated in the news
items and on this ML. And there's stuff on the wiki, e.g.:
https://wiki.gentoo.org/wiki/Upgrading_GCC

ISTR there's more specific stuff, but that's the gist of it. Rebuild
what depends on libstdc++. IIRC:

$ revdep-rebuild -v -p --library  /usr/lib/libstdc++.so.5

(change /usr/lib/ to whatever matches your platform and don't forget
/usr/lib32 if you do multilib ;)

It's much easier to use the '-o' option of ps, i.e.:

$ ps -eo pid,cmd

That gives you a much easier format to work with. There's a lot more
fields to use, e.g. tname or tty, args or cmd, comm, and many more see
'man ps' under "STANDARD FORMAT SPECIFIERS".

The following script does:

Yes. That's why I quoted the comment that the FQDN has to be first.

You can check with:

$ hostname
$ hostname -f

The former must give the short name ("syscon3"), the second one the FQDN
("syscon3.domain.tld").

I could download that file just fine just now[1]. Try running 'wget'
with the '-S' option. Oh and:

[..]
WARNING: cannot verify files.ontario.ca's certificate, issued by

If you sent stderr to /dev/null ...

So, try:

wget -S --no-check-certificate -U 'Mozilla/5.0 ...' \
https://files.ontario.ca/moh-covid-19-report-en-2021-01-14.pdf

BTW: you know that you can let date format that URL? e.g.:

wget -S --no-check-certificate -U 'Mozilla/5.0 ...' \
  "$(date '+https://files.ontario.ca/moh-covid-19-report-en-%Y-%m-%d.pdf')"

There just are no unescaped '%' allowed besides the format strings for
the date/time. So if an URL contains one, you need to escape those
with another '%', as in e.g.
$(date '+foo%%20bar-%Y-%m-%d.pdf')
^^ this fella

In your case, the URL is clean ;)

I already got one. Yes, I'd pitch MoBo w/many SATA vs. MoBo w/fewer
SATA plus AddIn, but PCI(e) slots are also limited and >=2 port cards
get expensive rather quick, say a card with >= 4 internal and
_extra_[0] 1-2 eSATA ... So, I'll rather have a MoBo with lots of SATA
+ addin than MoBo plus tons of addin cards...

My MoBo has the AMD 710 "Southbridge" with 6 int. SATA2/3G [1] ports,
a MV9128 with 2 int. SATA3/6G ports and a JMB362 with 2 ext. eSATA2/3G
ports. Try to find _anything_ even remotely resembling that (with any
SATA rev) ;) My guess is, with most MoBos you'd need two 4-port addin
cards even for that. And my MoBo was not even expensive, just ~80 EUR
in 04/2010. BTW: GA-770TA-UD3, hosting a AMD Athlon II X2 250 for then
~65 EUR :) Still running as champs :))

Again: find me a MoBo + Addin Card(s) Combo with: >= 9 internal SATA
ports, >=1 eSATA ports (dedicated, not switched with one of the
internal ones!). An IDE port would be a nice extra.

Were it not for gentoo and large stuff needing 6+ hours to compile,
the occasional reencoding of a video[3], and some fucking websites
which take ages to load (which was one reason for me to update 10
years ago from my then Athlon 500[2])... *ELIDED* those *ELIDED*

you can fit in 1 KB :).

Meh. I'm running an Athlon II X2 250, 65W TDP, i.e. same CPU family

over 10 years, I'd like to upgrade again a bit, Ryzen 5000 4-8core

Beware: I use a lot of disks and I tried running it with then 8 (or 9? 
or 10? Lots!) HDDs with a 500W (or even 550W) PSU. System wouldn't
reliably boot up. Replaced with a 650W PSU and it's running since
(which is, those 10+ years now :) Currently I have a SSD and 7 HDDs
(and 2 DVD[1]) ;)

Typical spinning rust drives are (or at least were) specced to take up
to about 30W while spinning up, ~10-12W-ish on access, ~5-7W-ish while
idle. For me, that then was ~240-300W alone for all the drives at
power-on. Too much obviously for the 500W PSU along with all the rest
of the box also starting ;)

I've got a nice Seasonic PSU from Corsair (TX650 v2) (the v1 was some
other stuff), only drawback is that it has gotten a bit clogged up
with dust and gotten loud and there's no easy way to clean it out (at
least without taking it apart) *sigh*...

Also, that Phenom X6 w/ 125W TDP is plenty powerhungry, even at idle
(ISTR 50W-ish, while modern stuff can take only 20-10W for the system,
aside from the HDDs in both cases).

No idea, but I'd go for a different case. And probably, depending on
budget vs. power-consumption (cost) for a different CPU+MoBo+RAM,
something like a AMD Ryzen 3 3200G or maybe a x86 Celeron/Pentium/i3...

I don't know urlview, but FWIW, I use the mouse or cursor in e.g. 
emacs to select the URL (or just a part) as usual and then
Ctrl+"8th-Button" (actually lower thumb button, use xev / evtest to
find the right button number) to call the browser, done via xbindkeys:

# call browser with selected text as URL
"/home/dh/bin/browser $(xsel -o)"
Control + b:8

You can use pretty much any unused key-combination with or without the
mouse as trigger.

(that ~/bin/browser is just my little wrapper-shellscript adding e.g. 
a profile option, a '-new-tab' if the browser is already running or
calling another unliked, but needed for some specific pages, browser...)

You seem to have a stray config file ;) I checked with the exact same
version as you and your config file and it gives me:

$ youtube-dl --config-location /tmp/test-ytconf
[..]
[debug] User config: []
[debug] Custom config: ['--format',

[debug] youtube-dl version 2020.06.16.1

(I use the seperate config to not overwrite mine, but I tested it with
my config and it also gives me:

[debug] User config: [ ...  '--format', 'best[height ...]

So, you seem to have some user config file which contains:

ytdl-format=bestvideo[height<=?1280]+bestaudio/best

instead of '--format[space]some_specs'. To find it the easiest, try:

$ strace -eopen youtube-dl SOMEURL 2>&1 | grep /home/

Is that one or two lines? It think it should be one! I.e.:

--format foo

Try:

--format 
'bestvideo[ext=webm][width<=?1280]+bestaudio/bestvideo[ext=mp4][width<=?1280]+bestaudio/best'

Looks good, but snd-hda-codec-hdmi might still get loaded, so try with:

options snd cards_limit=2

(or even more)...

Try:

before tackling FF etc. And check alsamixer etc. for it might have

Simliar here, but it'd be interesting, what actual device is that

This works here:

CONFIG_SND=y
CONFIG_SND_TIMER=y
CONFIG_SND_PCM=y
CONFIG_SND_HWDEP=m
CONFIG_SND_DRIVERS=y
CONFIG_SND_PCI=y

CONFIG_SND_HDA=m

CONFIG_SND_HDA_RECONFIG=y
CONFIG_SND_HDA_CODEC_REALTEK=m
CONFIG_SND_HDA_GENERIC=m
CONFIG_SND_HDA_CORE=m
CONFIG_SND_SPI=y

Not sure if CONFIG_SND_SPI and CONFIG_SND_HDA_GENERIC are needed, but
the other ones seem crucial.

Oh, the above is for a 4.14 kernel, but has been the same for a looong

Yes. Or put 'ones' in /root/bin/ or even /usr/local/bin. Depending on
if you expect to use the program later on. But if it's just for this
once it's fine in /root/ alongside the sourcecode.

I've wondered that too. So I just hacked one up just now.

 ones.c 
#include 
#include 
#include 
static unsigned int buf[BUFSIZ];
int main(void) {
unsigned int i;
for(i = 0; i < BUFSIZ; i++) { buf[i] = (unsigned int)-1; }
while( write(STDOUT_FILENO, buf, sizeof(buf)) );
exit(0);
}


Compile with:
gcc $CFLAGS -o ones ones.c
or
gcc $(portageq envvar CFLAGS) -o ones ones.c

and use/test e.g. like

./ones | dd of=/dev/null bs=8M count=1000 iflag=fullblock

Here, it's about as fast as

cat /dev/zero | dd of=/dev/null bs=8M count=1000 iflag=fullblock

(but only about ~25% as fast as 
dd if=/dev/zero of=/dev/null bs=8M count=1000 iflag=fullblock
for whatever reason ever, but the implementation of /dev/zero is
non-trivial ...)

You need 'media-sound/sox' and then use the silence effect. Note that
it is _one_ command on _one_line in that answer on stackexchange

I just remembered, that I tested back on 5.14.2[1], but, I just
re-emerged qtcore-5.15, qtwidgets-5.15 and qtgui-5.15 (which is all
cadence needs) and qtsvg-5.15 (for qt5ct that is called when running

I think something similar was on this list a couple of days ago, it's
a missing include (that wasn't neccessary before Qt5.15), there's 21
similar bugs filed already c.f.[1].

A quick and easy fix for this problem should be this:

1. create a file /etc/portage/env/missing-qpainterpath-flags and insert
  this line:


CXXFLAGS="${CXXFLAGS} -include QPainterPath"


2. add the line


=media-sound/cadence-0.9.0-r4   missing-qpainterpath-flags


to /etc/portage/package.env (or /e/p/package.env/qpainterpath.env or
some such if you've "directoryfied" your package.env (can you?) ;)

[add more lines for specific package versions and revs for the same
problem, see [1] for candidates]

Yes, that is *quite an ugly hack*, but could be handy while stuff get's
patched to work with that specific change of Qt5.15...

FWIW: that includes that QPainterPath header in _all_ C++ sources, but
what the hey, compilers are so good today, that they throw away
anything unused, so it should not matter. It'll slow down the compile
a bit...

Once e.g. media-sound/cadence is fixed and revbumped/versionbumped,
delete that line from package.env.

It works here for a quick:

WD Red WD*EFRX are PMR.
WD Red WD*EFAX are SMR (AFAIK, could be, that some are PMR).

ISTR, that the "Red Pro" are all PMR (so far).

ATA-8 is the current spec. Though practically unused. The used spec is
ATA-7 in virtually all drives for IIRC the last 10ish years or so.

Did you mean SATA specs? Well, then there's only SATA-1 (1.5GBit/s),
SATA-2, (3.0GBit/s) and SATA-3 (6.0GBit/s), and of the latter SATA
revision 3.1 introduced TRIM[2]. Oh, and rev. 3.3 introduced some
extras for SMR [3].

Beautifully summarized Rich! But I'd like to add two little aspects:

First of all: "physical write blocks" in the physical flash are 128kB
or something in that size range, not 4kB or even 512B ... Haven't
read, but looking enticing neither

https://en.wikipedia.org/wiki/Write_amplification

nor

https://en.wikipedia.org/wiki/Trim_(computing)

I hope they cover it ;)

Anyway, a write to a single (used) logical 512B block
involves:

1. read existing data of the phy-block-group (e.g. 128KB)
2. write data of logical block to the right spot of in-mem block-group
3. write in-mem block-group to (a different, unused) phy-block-group
4. update all logical block pointers to new phy-block-group as needed
5. mark old phy-block-group as unused

And whatnot.

And second: fstrim just makes the OS (via the Filesystem driver via
the SATA/NVME/SCSI driver through some hoops), or the Filesystem when
mounted with 'discard' via the drivers, tell the SSD one simple thing
about logical blocks that a deleted file used to use (in the TRIM
ATA/SCSI/SATA/NVME command, wikipedite for where TRIM is specced ;):

"Hey, SSD, here's a list of LBAs (logical blocks) I no longer need.
You may hencewith treat them as empty/unused."

Without it, the SSD has no idea about those blocks being unneeded and
treats blocks, once written to, as used blocks, doing the _tedious_
Copy-on-Write when a write hits one of those logical blocks, even if
those were deleted on the filesystem level years ago... see above WP
articles. Without TRIM, the SSD only gets to know the fact, when the
driver (the FS) writes again to the same logical block ...

With TRIM, the SSD-Controller knows what logical blocks it can treat
as unused, and do much better wear-leveling. So, it's sort of a
"trickle down 'unlink()' to the SSD"-feature. On the logical-block
level, mind you. But for the SSD, that can be quite a "relief"
regarding space for wear-leveling.

And what takes time when doing a "large" TRIM is transmitting a
_large_ list of blocks to the SSD via the TRIM command. That's why
e.g. those ~6-7GiB trims I did just before (see my other mail) took a
couple of seconds for 13GiB ~ 25M LBAs ~ a whole effin bunch of TRIM
commands (no idea... wait, 1-4kB per TRIM and 4B/LBA is max. 1k
LBAs/TRIM and for 25M LBAs you'll need minimum 25-100k TRIM
commands... go figure ;) no wonder it takes a second or few ;)

Oh, and yes, on rotating rust, all that does not matter. You'd just
let the data rot and write at 512B (or now 4kB) granularity. Well,
those 4k-but-512Bemulated drives (which is about all new ones by now I
think) have to do something like SSDs. But only on the 4kB level. Plus
the SMR shingling stuff of course. When will those implement TRIM?

Observe your use pattern a bit and use 'fstrim -v' when you think it's
worth it, as it basically boils down to how much you delete *when*. If
you e.g.:

- constantly use the drive as a fast cache for video-editing etc.,
  writing large files to the drive and later deleting them again

-> run fstrim daily or even mount with 'discard'-option

- write/delete somewhat regularly, e.g. as a system-drive and running
  updates or emerge @world (esp. if you build on the SSD) e.g. weekly
  they effectively are a write operation and a bunch of deletions. Or
  if you do whatever other deletions somewhat regularly

-> run fstrim after each one or three such deletions, e.g. via
   a weekly cronjob

- mostly write (if anything), rarely delete anything

-> run fstrim manually a few days after $some deletions have
   accumulated or any other convenient time you can remember to
   and are sure all deleted files can be gone, be it bi-weekly,
   monthly, tri-montly, yearly, completly irregularly, whenever ;)

Choose anything in the range that fits _your_ use-pattern best,
considering capacity, free-space (no matter if on a partition or
unallocated) and what size was trimmed when running 'fstrim -v'...

Running that weekly (I'd suggest bi-weekly) 'fstrim' cronjob is not a
bad suggestion as a default I guess, but observe your use and choose
to deviate or not :)

My gut says to run fstrim if:

- it'd trim more than 5% (-ish) capacity
- it'd trim more than 20% (-ish) of the remaining "free" space
  (including unallocated)
- it'd trim more than $n GiB (where $n may be anything ;)

whichever comes first (and the two latter can only be determined by
observation). No need to run fstrim after deleting just 1kiB. Or 1MiB.

Not that me lazybag adheres to that, read on if you will... ;)

FWIW:
I run fstrim a few times a year when I think of it and guesstimate I
did delete quite a bit in the meantime (much like I run fsck ;) ...
This usually trims a few GiB on my 128G drive:

# fdisk -u -l /dev/sda
Disk /dev/sda: 119.2 GiB, 128035676160 bytes, 250069680 sectors
Disk model: SAMSUNG SSD 830 
[..]
Device Boot Start   End   Sectors Size Id Type
/dev/sda12048 109053951 109051904  52G 83 Linux
/dev/sda2   109053952 218105855 109051904  52G 83 Linux

(I did leave ~15GiB unpartitioned, and was too lazy to rectify that
yet, at the time I partitioned in 2012, for many (cheaper?) SSDs that
overprovisioning was still a good thing and 'duh intarweb' was quite
worse than today regarding the problem)...

So while I'm about it, I guess it's time to run fstrim (for the first
time this year IIRC) ...

# fstrim -v /sda1 ; fstrim -v /sda2 ## mountpoints mangled
/sda1: 7563407360 bytes were trimmed
/sda2: 6842478592 bytes were trimmed

# calc 'x=config("display",1); 7563407360/2^30; 6842478592/2^30'
~7.0
~6.4

So, my typical few GiB or about 12.8% disk capacity (summed) were
trimmed (oddly enough, it's always been in this 4-8GiB/partition
range). I probably should run fstrim a bit more often though, but then
again I've still got those unallocated 15G, so I guess I'm fine. And
that's with quite a large Gentoo system on /dev/sda2 and all its at
times large (like libreoffice, firefox, seamonkey, icedtea, etc.)
updates:

# df -h /
Filesystem  Size  Used Avail Use% Mounted on
/dev/sda252G   45G  3.8G  93% /

PORTAGE_TMPDIR, PORTDIR, (and distfiles and packages) are on other
HDDs though, so building stuff does not affect the SSD, only the
actual install (merge) and whatever else. But I've got /var/log/ on
the SSD on both systems (sda1/sda2).

The patch spqr-1.2.3-autotools.patch is broken, it includes two

Did you reemerge x11-drivers/nvidia-drivers? If so your profile might
have switched if off and then read on ;)

>...because I am on a 64bit-only system???

Possibly, I'm not firm about all that profile stuff. If you've
selected a no-multilib profile (e.g. 
default/linux/amd64/17.1/no-multilib), I guess that -multilib might be
switched off by the profile, even overriding your useflag in
package.use[0].

In that case, try this (create dirs/files as neccessary):

 /etc/portage/profile/package.use.force ===
x11-drivers/nvidia-drivers  multilib


If that does not work, try:

 /etc/portage/profile/package.use.mask ===
x11-drivers/nvidia-drivers  -multilib


(it's a matter of how it's switched off via the profile, AFAIK).

BTW: you do not have to emerge the package to see the effect of those
edits, an 'emerge --pretend ...' will show you if the 'multilib' flag
will be honored or not.

Looking at the ebuild, it seems that it only installs libnvoptix when
multilib enabled is *and* if it's on amd64:

 x11-drivers/nvidia-drivers/nvidia-drivers-440.64.ebuild 
if use kernel_linux && has_multilib_profile && [[ ${ABI} == 
"amd64" ]];
then
NV_GLX_LIBRARIES+=(
"libnvidia-cbl.so.${NV_SOVER}"
"libnvidia-rtcore.so.${NV_SOVER}"
"libnvoptix.so.${NV_SOVER}"
)
fi


And that's the only occurrence of optix in the ebuild. In driver,
there's only a 64-bit libnvoptix.so.440.64 included, it's missing from
the ./32 subfolder, so I guess that optix stuff it's 64bit only.
But that dep on has_multilib_profile seems buggish to me. Test /
workaround: Just add 'multilib' to your package.use flags of
x11-drivers/nvidia-drivers (and _do not set_ e.g. abi_x86_32), just
switch on the 'multilib'. If that works and libnvoptix.so is then
installed and Blender works with it, I'd say it's a bug that those
libs should only be installed with multilib on. My guess is, that the
intent and/or right way would be to just omit that multilib dep. Apart
from other useflags that could be used. I.e. it should be:


if use kernel_linux && [[ ${ABI} == "amd64" ]];
then
NV_GLX_LIBRARIES+=(
"libnvidia-cbl.so.${NV_SOVER}"

If you mean TBW by "lifetime": All above factor 2, best: over 18. Ok,
those were the "brand models" (1 Crucial, 1 OCZ (Toshiba), 2 Samsung
and 2 Sandisk, and 2 drives of each model)...

Fun fact: one of the test PCs died and killed two of the 3 remaining
SSDs, the second Sandisk Extreme Pro (the first had died already) and
the first Samsung 850 Pro. The remaining second Samsung 850 Pro in the
other Test-PC was still being hammered 4.5 months later with 8 PeBi
written (all drives were 240/256 GB), but showing first "Uncorrectable
Errors" via SMART.

The test also included the failure mode as well, e.g. "dead as a
brick" in a moment, warning signs via SMART, failure to write but
still readable etc.

The mag followed that up with a test of el-cheapo SSDs ... which I'll
include in my summary.

I guess Intel did (still does?) that too, but you'll have to check
that, ISTR that Intel now sells SSDs with non-Intel controllers and/or
non-Intel/"IM-Flash" flash-chips... Oh, wait, yes, Intel still does,
but those "pure Intel" SSDs come with a *very* hefty price (like 4
times as much) and all the "normal" priced ones are those with either
and/or non Intel flash-chips and/or -controllers... But please go
check that yourselves though!

The second thing I remembered: the german "c't"[2] magazine did a
torture test in late 2018 (IIRC), basically grabbing a few then
current SSDs and run their own testtool[1] on them until they died. Or
so was the plan. That was a "write till it dies" test.

First of all: all SSD exceeded their specs, some IIRC just barely. The
bulk by a factor of 2 or more. ISTR some of those "just barely", but
wont name them without digging out the actual results, which I'll do
upon requests.

The test had one problem though: a (IIRC) Samsung 850 Pro just refused
to die ;) They aborted the test after something like over 4 months
(all other drives had died inside of about a month) of _continous_
writes (or write-verify cycles) to that one remaining SSD, which was
still happily chugging along...

I do remember though, that even the Samsung EVO came out at the top of
the bunch

(Note: c't does not award a "test-winner" or anything. Just data and
an conclusion aka "Fazit", the reader has to digest the data and make
up his own mind for _her/his_ own usecase).

All IIRC, I can dig out and translate the details though! (and it's

And they produce and use their own controllers, so they additionally
know the ins and outs of those, i.e. they can easily optimize the
whole SSD from Flash-Chip over controller up to the firmware...

Dunno if the same is true for Micron+Intel (IM Flash) / Crucial. Seems
no, as e.g. the Crucial MX500 uses a Silicon Motion controller, even
though Micron does (or did) produce controllers. Nor does WD, it seems.

AFAIgathered, Samsung is the only one producing the whole product.
Albeit, I heard rumours, that the various divisions of Samsung could
as well be different manufacturers[1], but how far apart the

First of all, decode that C++ symbol with c++filt:

$ echo 
_ZN3fmt2v68internal14sprintf_formatIeEEPcT_RNS1_6bufferIcEENS1_13sprintf_specsE 
| c++filt 
char* fmt::v6::internal::sprintf_format(long double, 
fmt::v6::internal::buffer&, fmt::v6::internal::sprintf_specs)

Now, with a bit of guesswork and tabbing, 
$ grep -r sprintf_format /usr/include/fmt/
/usr/include/fmt/format.h:void sprintf_format(Double, internal::buffer &, 
core_format_specs);
/usr/include/fmt/format.h:internal::sprintf_format(value, buffer, 
normalized_spec);
/usr/include/fmt/format-inl.h:void sprintf_format(Double value, 
internal::buffer &buf,

It looks like the middle one, from /usr/include/fmt/format.h, i.e.
internal::sprintf_format is the culprit. And

$ qfile  /usr/include/fmt/format.h
dev-libs/libfmt: /usr/include/fmt/format.h

gives us the package it belongs to. Guessing from the symbol name,
kodi wants v6 of that library. I've got dev-libs/libfmt-5.3.0:0/5
installed, and on a hunch, running "symgrep"[1] (or nm | grep) on the lib
itself gives:

$ symgrep internal::sprintf_format /usr/lib64/libfmt.so
   275: 000108a0   283 FUNCWEAK   DEFAULT   11 void

$ nm /usr/lib64/libfmt.so | c++filt | grep sprintf_format
000108a0 W void fmt::v5::internal::sprintf_format(double,

000109c0 W void fmt::v5::internal::sprintf_format(long 
double, fmt::v5::internal::basic_buffer&, fmt::v5::core_format_specs)

Ahhaa, we've got fmt::v5::* and not fmt::v6::*! And yes, on this box it's:

$ ls -l /usr/lib64/libfmt.so* 
lrwxrwxrwx 1 [..] /usr/lib64/libfmt.so -> libfmt.so.5
lrwxrwxrwx 1 [..] /usr/lib64/libfmt.so.5 -> libfmt.so.5.3.0
-rwxr-xr-x 1 [..] /usr/lib64/libfmt.so.5.3.0

So, you should rebuild kodi. So it gets linked to your installed
libfmt. And/or update your libfmt to v6.

Oh, and BTW, if you don't have the depended on package installed,
searching for the missing symbol online usually gives some hints of
where it comes from.

With an '<' in front of it (and it has), it means that
inkscape-1.0_beta1 needs imagemagick <= 7 i.e. some 6.x version ... 

Basically it means you should mask that inkscape beta. Add e.g.

=media-gfx/inkscape-1.0_beta1

to /etc/portage/package.mask[/*].

Or (better) un-keyword ~amd64 inkscape, then you should stay at the
(now) stable 0.92.4.

Have you moved your /usr/lib* stuff to the new layout yet? I.e.
is /usr/lib a symlink to /usr/lib64 or is it a directory containing

Why not use 'genkernel'? The default-config should work in your case,

the BOOTLOADER variable. Then 'cd' to your kernel-sources-dir and run

The screensaver has to get _and keep_ the lock on input.

The sad thing is, people do needless rewrites and get it wrong again
and again and again, despite jwz' xscreensaver code from 1991 on,
setting an example on how to do it right... Cue gnome-screensaver, the
kde stuff, apparently also i3lock etc.pp. ad nauseam, all repeating
the very bugs jwz wrote about in 2004 (the toolkits.html)...

VT Switching is just a little subclass of the underlying problems of
those "lock screen" programs that don't lock your screen.

 https://www.jwz.org/xscreensaver/toolkits.html / Epilogue 
I wrote this document in 2004, explaining the approach to privilege
separation that xscreensaver has taken since 1991. Of course, the
people doing needless rewrites of xscreensaver have ignored it for
that whole time, and have then gone on to introduce exactly the bug
that I described in this document as a hypothetical strawman! And --
this would be hilarious if it weren't so sad -- have introduced it
multiple times. As I said in 2015:

If you are not running xscreensaver on Linux, then it is safe to
assume that your screen does not lock. Once is happenstance. Twice
is coincidence. Three times is enemy action. Four times is
Official GNOME Policy.

(read the whole thing linked document!). Also:

https://www.jwz.org/xscreensaver/man1.html#8
https://www.jwz.org/blog/2014/04/the-awful-thing-about-getting-it-right-the-first-time-is-that-nobody-realizes-how-hard-it-was/
https://www.jwz.org/blog/2015/04/i-told-you-so-again/
(also follow the "previous" links ;)

So the solution is to just use "xscreensaver" by jwz. Which can be
configured to just blank the screen etc. as wanted by the op. See also
the FAQ: https://www.jwz.org/xscreensaver/faq.html

Your term looks rather low contrast with that rather bright dark

You can also adjust the colours see 'man 5 color.map' and
/etc/portage/color.map.

And/or even patch emerge's output routines (I think there's some stuff
that has no variable in color.map, and which is hard to read on
grey5). I use this:

>man pages in color are the other most important problem right now. I will
>check out your suggestion.

AFAIK that mostly depends on what you use as pager for man, e.g. less.


   Controlling formatted output
   -P pager, --pager=pager
  Specify  which  output  pager to use.  By default, man uses less
  -s.  This option overrides the $MANPAGER  environment  variable,
  which  in turn overrides the $PAGER environment variable.  It is
  not used in conjunction with -f or -k.


So, have a look at the MANPAGER and PAGER variables if they're set. If
they are, have a look at the config of that pager, else at that of
'less(1)'. Oh, and have a look at your terminal options. E.g. use
'xterm -cm' instead of 'xterm'... (or set the according Xresource) and
all you get is black & white ;)

Not quite.

[[:digit:]]+ == [0-9][0-9]*

Not too, that [:digit:] respects locale. Don't know where locale
applies though. Probably Devanagari or such. I just made myself to use
classes rather than char-ranges. See man 7 regex for more classes.

Nah, cpupower seems to be even older that gkfreq, but that is also at
least from 2010 ;) IIRC I found it linked from the gkrellm homepage.

You can configure it! But cpupower seems to take at least a
line/CPU-Core. BTW it seems you have to restart gkrellm to have
cpupower update it's config, unlike most other plugins (e.g. gkfreq ;)

>Thanks for the tip tho.  I'm going to check into the other plugins that

gkfreq can be configured that it just shows one line (e.g. "Max",
which is how I have it), and which suits me. Oh and with that slower
update-rate in my other follow-up with the patch.

Check both out. You can use both cpupower and gkfreq for testing and
keep whichever you like better ;)

I miss my Matrox Mystique (first model w/170MHz RAMDAC!) with a
whopping 4 MB SGRAM, and not even a heatsink, just the plain naked
chip, much less a fan, and it ran in a PCI slot, at about ~4.5W (or
was it 5W?) theoretical max usage...

https://en.wikipedia.org/wiki/Matrox_Mystique
https://en.wikipedia.org/wiki/File:MatroxMystique2MBcard.jpg

I only replaced that ~10yearish ago because my new screen had a
whopping 1280x1024 on 17", which those 4MB just won't do at decent
bit-depth... *sigh* For 1152x864 on the CRT it was still good, but
that screen just got too dark to see anything at all, so I had to
replace it. Got a nice (expensiveish) PVA-TFT. Still very nice after
~10 years, even with CCFL it has darkend only minimally[1] :) And yes,
I'm still fine with 1280x1024 on 17", TYVM :) I could even set up the
spare monitor (same size/res) alongside, but I just don't need it.

Now, I've got (again) a passive GPU for PCIe (max. 75W) w/o extra
power. Main reason: the latest had a fan, which started to scream. As
in almost not running. Cleaning did not help. So... No fan, no sound,
and cleaning a heatsink is easy, as opposed to cleaning a fan +
heatsink combo. And besides, a downward-facing heatsink does not
tend to clog up as one that has a fan blowing onto it...

Just updated the one in the tree in my local overlay, see attached
indilib-1.7.5.ebuild.

Oh, and I updated sci-astronomy/kstars to 2.9.8 there too, see also
attached inside a tarball with patches... Oh, a note on that, I've
added the knewstuff IUSE as I like to disable that generally, but as
it's a '+'ed, you should be fine. Not sure what the qtdatavis3d

Are you using a kernel <3.15?

Found this at :
"Qt 5.10 uses the renameat2 system call which is only available
since kernel 3.15."

No wonder. The error was e.g.:

Check with

Use 'pgrep [-u UID/USERNAME] pattern' or adjust ps output to only
display what interests you, e.g.:

$ ps -eo pid,cmd
$ ps -eo pid,cmd | awk '$2 ~ /pattern/ { print $1; }'
$ ps -eo pid,cmd | awk '$2 == "string" { print $1; }'

etc.

Or try 'pidof' (which needs the exact command-name and might return
mismatches).

First of all, I've seen quite a big boost just by using '-O3'!

My speeding-up-relevant flags (for a Athlon II X2 250 "Regor") are:

-O3 -march=native -mtune=native -mfpmath=sse -msse4a \
-funwind-tables -fasynchronous-unwind-tables

You'll have to adjust -march=/-mtune= for the Atom and -m* for both,
crosscheck with e.g. 

$ grep ^flags /proc/cpuinfo |tr ' ' '\n' |grep sse | sort -u
misalignsse
sse
sse2
sse4a

or app-portage/cpuid2cpuflags.

And/or setup some wrappers/shell-functions, that setup flags like:

 emerge-atom ===
#!/bin/sh
FEATURES="buildpkg"
PKGDIR="${PORTDIR}/laptop_binpkg_dir"
export CFLAGS="..."
export CXXFLAGS="..."
...
emerge "$@"


and then use 'emerge ' for the desktop and 'emerge-atom' for the
laptop. Or something along those lines.

On the other paw, one could run some benchmarks, comparing both native
flags vs. the "common demnominator" (and -O2 vs -O3 ;)...

In the meantime, put the attached patch into
/etc/portage/patches/dev-libs/appstream-0.11.5/
e.g. as appstream-0.11.5-po_meson_build.patch

We've got a rare case of "over-escaping" in the meson.build for once,
as meson seems to replace '\\' even in commands by '/', so we end up
with '/n' instead of '\n', i.e. "find -printf '%f/n'" instead of
the correct "find -printf '%f\n'". The single '\n' get replaced by
meson by an actual linebreak, so that works too.

Upstream has fixed it in .8 by putting that stuff into an extra script
see 
https://github.com/ximion/appstream/blob/master/contrib/meson/update-linguas.sh

Nope. You need microcode_amd.bin, if any. Go into the git-repo for
