Oops, I missed a step: `jekyll new myblog && cd $_ && bundle exec jekyll

I got jekyll installed via portage by adding:

dev-ruby/* ~amd64
www-apps/jekyll ~amd64
www-apps/jekyll-* ~amd64

to package.accept_keywords, and then running `emerge www-apps/jekyll'. This is 
on stable, with a tree that is a couple weeks old for what it's worth. Then 
`jekyll new testsite && bundle exec jekyll serve' works for me.

You could also try using jekyll outside of portage:

mkdir mysite && cd mysite
bundle init
bundle config set path 'vendor/bundle'
bundle add jekyll
bundle exec jekyll new --force .
rm Gemfile.lock
rm -rf ./vendor/bundle
bundle config set path 'vendor/bundle'
bundle install
bundle exec jekyll serve

And then continue following other jekyll instructions as needed. You'll have to 
use `bundle exec jekyll ...' to run jekyll - you won't be able to run jekyll 
directly.

Hope this helps,

Depending what desktop environment/terminal emulator, there are a few options. 
You could use a terminal like gnome-terminal, konsole, etc. which have scroll 
so you can run `emerge -ca' and scroll to view the results. I run urxvt in i3 
(not sure whether it scrolls or not), and I always run emerge inside of a tmux 
and use tmux's scroll to view all the output before making a decision, so you 
could also use tmux or screen.

Hope this helps,

Generally, I just `sudo ebuild  clean install merge'
and test that it works directly on my system. I only proxy-maintain 1 package,
though, so others will probably have much better workflows.

If it's so easy, why don't you implement it? /s

Sorry for being a little glib but every couple months I go through this thought 
process:

1. Wow, portage is slow
2. I can make this faster, it can't be that hard
3. ...wow, nevermind, it is really hard
4. Thank you portage maintainers!

I don't think it's O(log n). Roughly, for 1 package portage has to make the 
full dep
tree, solve all the constraints to resolve to actual packages that can be 
installed,
and order and merge the tree into a single branch of packages to install. I'm
probably missing some steps and obviously that's not a rigorous explanation but
it's at least O(n) where n is the total number of dependencies.

Cycles make it even more complicated, and I'm not up on the latest algorithms
to resolve these and know how fast they are.

Speeding up portage would be a fun project but it's less important
that portage being correct.

I use urxvt and I've always done Ctrl+Alt+V for paste. If you try that, what

My understanding is that it reports running processes and other info about your 
machine back to Zoom. Don't know why. As soon as I'm done with a meeting, I 
stop it so it's not running all the time.

That's why I would move it to a VM - libvirt/KVM/spice seems to have pretty 
phenomenal support for cameras, mics, and other "advanced" features these days.

I've been using Zoom for a few months with the flatpak from flathub 
(https://flathub.org/apps/details/us.zoom.Zoom). Flatpak makes it very easy, 
handles updates, etc. which is why I started running it that way.

Given all the stuff I've heard about Zoom in the past week related to how much 
info it takes from your machine while it's running, I may be moving it into a 
VM pretty soon.

Probably the easiest way would be to download the gentoo boot CD or the LiveCD 
of another Linux distro, boot the computer w/ the LiveCD, mount the hard drive, 
and see if there's anything you need that way.

Once you're booted from a LiveCD, you could also chroot into your Gentoo 
install and prevent MySQL starting on boot with OpenRC/systemd if you wanted to 
reboot from Gentoo and look at your files from Gentoo.

I just don't know what I'm doing - I can switch virtual consoles too. I

Based on a cursory look[1] I'd guess this would be something that
i3lock has to implement. Or just workaround by using tmux or screen
instead of virtual consoles as someone else suggested.

Which init are you using, what display manager, and how are you
launching it? I'm using systemd and sddm, and when I run `i3lock', I
cannot switch to different virtual consoles.

Not sure whether any of that stuff matters, but that was the first thing

That's a good rule but not necessarily always true. My old machine was an 
i7-3930K (6 cores, 12 threads) w/ 32G RAM. I had /var/tmp on tmpfs. I 
benchmarked firefox, chromium, and some other big projects once and -j13 was 
consistently the fastest on that box.

As that blog post says:

Depends on available RAM, how fast your disk is, etc.

They work pretty well for me. I have an RX 570 (and a Ryzen 5 1600), works 
great for the most part but in all honesty it did take me a while to find a

All I play is CS:GO, which runs very well. I've played a bit of Rust too, which

I do the same thing, except mine are printed off and in the safe. IMO it
boils down to what you're trying to defend against; if someone cracks
your safe passwords are probably the last thing to worry about. I'd
imagine by getting into someone's safe you could get enough documents

Of course all my passwords that are stored on my computer are encrypted

IMO that's totally fine. I just built a new rig to use for programming

I have used `gpg' to do this before:

# Encrypt with a passphrase
gpg -c 

# Decrypt
gpg -d .gpg

I do have some files I keep encrypted locally that I use `gpg' to
encrypt/decrypt, but with my personal key pair. For that, I use a vim
plugin[1] that transparently decrypts to `/tmp', lets me edit, and then
saves back to the original file. This prevents the decrypted contents
from ever being on my hard drive, as I have `/tmp' mounted as tmpfs.

I see this at the top of gdb-7.12.1.build:

PYTHON_COMPAT=( python{2_7,3_4,3_5} )

For the mean time, you can either accept the breakage, set
PYTHON_SINGLE_TARGET="python3_5" in /etc/portage/make.conf for now, or run an
unstable gdb.

How about `emerge --info | grep PYTHON_SINGLE_TARGET'? The problem looks
to be:

At least one PYTHON_SINGLE_TARGET needs to be set. I'd guess that
PYTHON_SINGLE_TARGET got updated to 3.6, leaving GDB in its dust.

Yes, after every world update. I'm not sure why python-3.5 was removed.

Before you set PYTHON_TARGETS in make.conf, had you run an `emerge
--sync' in a while? It's possible the default PYTHON_TARGETS from your
profile did not include python-3.5, so --depclean would have removed it.

No, you shouldn't need any dev-lang/python entries in the world file. I

Instead of running Gentoo with VirtualBox and backing up the image, I'd
recommend storing your configurations in a git repo and using ansible[1]
or salt[2] to deploy them when you need to.

Also, if you ever expand to more than 1 server, these tools make even
more sense. I use salt for my personal setup, which is 1 server and 1
laptop (I have 2-3 more servers that I need to get set up someday...),
but salt is simpler and no less powerful.

Hope this helps,

I remember in college some interesting work in security-related stuff

Potentially that could be useful, as you could record the waveforms
going into your power supply while rendering a PDF, but it sure sounds
complicated.

Even if you could talk to these, taking periodic measurements of
current and voltage, then integrating over time would probably give
results with large errors.

Due to modern processors having things like pipelines and all of the

not easy to measure this with any degree of accuracy.

I'm not sure; I always use new-use. If you haven't synced and updated recently,
you may have issues as the default profiles still had ruby-2.1 listed in
them.

Yes, that should be fine. I rarely look at portage output and just run

As Hans also mentioned, the upgrade itself will not automatically run

I don't believe that will be enough. You should update RUBY_TARGETS in

are still getting this error, that's a bug and should be filed on b.g.o. 
I have a custom RUBY_TARGETS as I do some ruby development, so I don't 
have a vanilla system to test this on.


Also, you'll have to run a slightly different command to update (since 
RUBY_TARGETS, PYTHON_TARGETS, etc. are USE flags underneath):


emerge --update --newuse --deep @world

You shouldn't have to 'eselect ruby' either - portage will do this for 
you while updating.

I'm not Rich but I'm sure that's what he means. I have an SSD, and using
a tmpfs for building speeds up builds significantly - probably 10-15%.

This will mean that you'll need a significant amount of memory allocated
to the VM. Mounting a tmpfs defaults to half of the memory available to
the machine, which seems like a decent rule of thumb. If you give the VM
8GB of memory, the tmpfs will have 4GB of space.

Hmm, okay. I have noticed some slowness when baloo is running, as
Fernando mentioned. I turned off file indexing, which does not seem to
have actually done anything.

Anyways, other than that, KDE for me runs very smoothly. Most of the
time, even when baloo is running full out, KDE itself is very
responsive. Qt Creator currently segfaults when I try to create a new
project or open a project, but other than that is generally responsive.

Which version of Qt Creator are you running?

Just double checking; what is the value of these config keys in your

That sounds cool. `emerge -uDN --with-bdeps=y @world' should do
approximately the same thing, though.

1. Write some sql scripts that compute the data you need and output CSV,
then import to Gnumeric and do the plots.

2. Write python script(s) that run SQL commands and plot the data with
matplotlib.
3. Write a webapp so you don't have to run scripts by hand - the plots
are generated by opening a web page.

4. Write it all in C++ :)

Something I could use (and others):
A simple PHP page which I can feed:
- connection parameters to a database
- select-query
- which result-field to use for the horizontal axis
and then plots the remaining fields for the vertical axis.

I haven't checked with google yet, so if there is a decent example, I'd be

Google gave me nothing. I have not written PHP for a long time, and I'm 
so unfamiliar with deploying/running PHP that it would take me a long

Another option is R - I just did some searching, and it supports pulling 
data from a database. R's basic plotting functions are real nice. I 
imagine a script could do some basic queries + plotting in 20-30 lines.

   Why I want postgresql... I've been keeping a bunch of data in a
spreadsheet, and it's gotten too large.  The spreadsheet locks up my
system when I try to update it.  I've used "top" and watched as
gnumeric's memory consumption grows to eat all available ram.  It locks
up the system so I can't even ssh in.  This is on an X86_64 with 8 gigs
of RAM!  Fortunately, "magic-sysrq" allows a relatively clean shutdown.
While we're at it, is there a way for gnumeric to pull in data directly
from postgresql?  ODBC?  I'm aware of copying from postgresql to a CSV
file and importing that, but it's rather clunky.


`equery use gnumeric' gives the `libgda' flag, which should pull in 
database support. I've never used it, so I don't know whether or not it

PYTHON_SINGLE_TARGET sets the version of python for a package that can
only be installed with a single python. PYTHON_TARGETS sets the versions
of python a python package will be installed to/with for packages that
can be installed to multiple python versions.

You have PYTHON_SINGLE_TARGET=python3_4, but PYTHON_TARGETS does *not*
contain python3_4. This is bad.

You almost certainly want this to be:

emerge --update --verbose --oneshot portage

"--oneshot" will prevent portage from being added to your @world set.

Add "--oneshot", same reasoning as above.

add "--ignore" to ignore any cached files and fully examine the system.

Apparently it does not. I know it does that for individual packages, so

app-office/libreoffice-5.1.0.3 requires PYTHON_SINGLE_TARGET to be
python3_4 or python3_5. That's the only problem. I would recommend

Until the new version gets added to the tree, I would run docker-compose

Sadly, I won't be a whole lot of help. I am experiencing the same thing,

In general (someone else, correct me if I'm wrong) this list would much
rather have you attach a compressed build.log when you mail in the
problem. That way, there is no chance of permissions problems, and years
from now, the logs will still be here for posterity.

The problem is a python script that runs in the build process has a
KeyError. I did notice that for you, that python script is running on
files in `/usr/local/share/xcb', while it runs on files in
`/usr/share/xcb' on mine. These are a part of the `x11-proto/xcb-proto'
package. Do you have a version of xcb-proto installed in /usr/local? It
is possible that the libxcb configure script is picking an old version
of xcb-proto that is installed in `/usr/local' over the correct version
installed in `/usr'.

I would recommend removing `/usr/local/share/xcb' and trying to install
libxcb again.

I am not extremely familiar with how sound works, to be honest. I do
have the 'alsa' USE flag set on pulseaudio. Here are the modules I have
loaded in /etc/pulse/default.pa:

module-always-sink
module-augment-properties

Sorry, I misled you. I do not have any software configured to use ALSA
as far as I know, but pulseaudio is configured with the 'alsa' USE flag
as I mentioned above.

Almost. Here is an equal example: I am an admin on an HPC cluster. We
have a shared Lustre filesystem that people store work files in while
they are running jobs. It has around 1PB of capacity. As strange as this
may sound, this filesystem is overcommitted (we have 20,000 cores,
that's only 52GB per core, not even close to enough for more than half a
year of data accumulation).  Unused data is deleted after 90 days, which
is why it can be overcommitted.

Extending this to a more realistic example without automatic data
deletion is trivial. Imagine you are a web hosting provider. You allow
each client unlimited disk space, so you're automatically overcommitted.
In the aggregate, even though one client may increase their usage
extremely quickly, total usage rises slowly, giving you more than enough
time to increase the storage capacity of whatever backing filesystem is
hosting their files.

Yup, seems pretty good. Probably doable with a very simple ebuild, since
all its dependencies are already in the portage tree.

Well, the heroku client seems to be moving in the same direction as
vagrant[1], although hasn't gone nearly as far yet. In the heroku
gemspec, there is a post install message that warns gem install is
deprecated. I'm not terribly familiar with ruby, but it looks like it
should still be installable from source.

I can. Ruby is not nearly as well supported in Gentoo as python is. An
average ruby developer wanting to use the heroku client would most
likely already be using either rbenv or rvm already, and would probably
run `gem install heroku' without even looking if an ebuild exists. My
roommate certainly would do this; he runs Gentoo, but solely uses
bundler and rbenv to manage ruby stuff (except for installing the
interpreter itself).

Alec

[1] vagrant used to be installable as a gem (and therefore not terrible
to package), but then the authors decided that it would be way to
difficult to support all these people with all these versions of
different libraries, so they would make it difficult to manually package
and only ship installers with bundled deps.

Have you looked at dmesg and/or any ALSA logs to see why ALSA-related
stuff can't be initialized? Intel hardware and drivers have always
treated me well, so this is strange.

Alec

P.S. Is there a particular reason you are using pulseaudio as a layer
above ALSA? If not, you might just use PA in my opinion.

Depends on how the load is. Right now I have a 500GB HDD at work. I use
VirtualBox and vagrant for testing various software. Every VM in
VirtualBox gets a 50GB hard disk, and I generally have 7 or 8 at a time.
Add in all the other stuff on my system, which includes a 200GB dataset,
and the disk is overcommitted. Of course, none of the VirtualBox disks
use anywhere near 50GB.

All Joost is saying is that most resources can be overcommitted, since
all the users will not be using all their resources at the same time.

Use a configuration management tool like puppet or ansible. It will take

Or in other words, if you own example.com and an auth server for

The name server doesn't know what domains it's supposed to give answers

If you have a DNS server that is serving DNS info for example.com, it 
*does* know that. However,
what Alan is saying is that none of the resolvers (not even the resolver 
running on your
example.com DNS server) knows which DNS server serves records for 
example.com without

a few more queries.

Assume a resolver (for example, the resolver in glibc) that has no 
cached knowledge. To
look up www.example.com, it first queries for '.com' from the root DNS 
servers. Next, it
queries for 'example' from the '.com' DNS servers. Finally, from the 
'example.com' DNS

server, it can get the IP for www.example.com.




DNS was designed to need a network connection because most of the DNS is
out there somewhere else

Then how do you solve the problem of being unable to even resolve the
names of hosts on the LAN when the connection goes down?


Ideally, your caching name server has cached the record for your domain 
by the time

your connection goes down.

That makes sense. In my apartment I have a dedicated Netgear router and a
dedicated TP-LINK AP. The AP was around $20, and has fantastic range.
Having a dedicated AP sounds way easier to me than trying to do a
dual-stack thing.

Now that I think a bit more about it, having a wireless AP and a
wireless client on the same chip doesn't sound good, since one MAC
address would be doing two functions. That said, I am not even close to
a networking guru; I hope someone else can chime in.

I can't help but think you are approaching this from the wrong perspective.

Why exactly are you using compile times as your sole criterion? Are you
building a compile farm for Ubuntu? Running continuous integration tests
for LibreOffice [on a $600 budget in a cardboard box :-) ]?

Or do you want emerge world to get it over with quicker?

If the latter, you better rethink your priorities. In computing terms,
compilation is a rare event; launching apps is a common event; and
writing to the disk happens all the time. Optimize for the common case.


In addition, upgrades are something that can be done overnight, or 
really any time you are not using the machine.




A CPU never works in isolation, it is always part of a much larger
system, like disks, RAM and all possible kinds of I/O. The best CPU on
the market plugged into a POS motherboard will perform on emerge world
like a piece of shit - it will follow the weakest link.


This; I have an i7-3930K, which has 6 physical cores at 3.8GHz. I also 
have 32GB of RAM and an SSD. There was a large speedup[1] moving 
portage's workdir from SSD to tmpfs. Compiling is a really balanced 
workload, stressing the disk (multiple small reads), memory, and CPU. 
For fast compilation, emphasize RAM first (compile in tmpfs if 
possible), then CPU, then disk. Like Alan said, though, you should 
really optimize for the average case on not worry about the speed of 
compiling stuff.

What desktop environment are you using? OpenRC or systemd? Lastly, do
you have support for suspending to RAM compiled into the kernel?

If you are using a desktop environment, it should have the suspend
functionality built into it. If you are using systemd, it should be as
simple as a `systemctl suspend`.

I seem to recall the list having a discussion about gentoo-sources vs.
vanilla-sources a while ago, and I believe Rich doesn't use the gentoo
patches. It doesn't seem like he does, since just above he mentions that
he builds and runs kernels from a checkout of a git repo from
kernel.org.

The stable tree is
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git.
Only X.Y tags go into Linus' git repo, not X.Y.Z. When they switched
from version 2 to version 3, the numbering scheme changed a bit. Any
kernel version with a third version number is either stable or long
term, and if the last number in the version is more than 8 or 10, it is
probably going to be a long term kernel.

This is pretty much the rationale that I use for updating - as soon as a
kernel version higher than the one I'm currently running has the last
number in the version hit 8 or 10, I upgrade.

Actually, I think modern versions of ffmpeg probably do not benefit as
much anymore. The `cpudetection' USE flag makes me think ffmpeg uses
the CPUID instruction to determine which x86 extensions are available,
and loads the appropriate code. This would enable Ubuntu et. al. to
build ffmpeg with all the high performance code compiled, and still be
compatible with all CPUs. I do not know if that is 100% true, but having
a `cpudetection' USE flag makes me assume that's how it works. More on
this here, which is the top of list when I searched "ffmpeg cpu
detection" [1].

For plenty of packages, such as fftw, this is a huge benefit. fftw does
not have a `cpudetection' USE flag, so I would assume that sse, avx,
etc. must be determined at build time and can't be changed at runtime.

I am running 4.1.8 on all my machines without any problems. Without
seeing the stack trace and/or other output from the kernel panic, I
would have no idea how to figure out what the problem was. I am also not

I have been using all the system-* flags as long as I can remember. I
can't remember the last time that I rebuilt firefox for a reason other
than a version update or I had directly changed its USE flags. I usually
update weekly, so I see firefox rebuilds probably once a month or a

As far as I can tell, the same tarball is downloaded no matter which
system-* USE flags you set. The ebuild tells the build system to use the
system stuff.

Enabling the use of system libraries could make Firefox unstable, since
the FF developers may have patched the bundled libs. It will also save
compile time, although compared to FF itself, most of the libs that can
be prevented from bundling have short compile times.

For me, personally, disabling those USE flags and using bundled libs
represents some sort of idealogical loss since I view bundling libraries
as a cop out solution. This may or may not matter to you.

Someone (I can't remember who, probably Rich Freeman or some other dev)
described a problem with the general process of fixing the portage
output a while ago. I believe the steps went something like this:

1. Think the portage output sucks
2. Learn what the output means
3. Lose all motivation to improve the output because it is no longer
   necessary for you

The portage output is not as good as it could be, but everyone with the
knowledge to fix it doesn't because they neither care (because they
understand it) *nor* are they being paid.

In my opinion, the portage output is not that bad, in the same way that
gcc's error messages are not that bad. They can be difficult to get used
to and some of them are absolutely ridiculous, but after using gcc for a
while they almost always make sense and are precise.

Like all good language authors, the ghc authors wrote a lot of the

There is a 'ghcbootstrap' USE flag that you can set to use your locally

Unfortunately, the right way with nodejs/ruby web stuff is to use the
tooling specific to the language. If this[1] is what you're trying to
deploy, I feel sorry.

If I was serious about deploying this, I would:

1. Fork the repo and add a remote on my own server
2. Add your custom configuration
3. Write a small shell script that
  1. Runs `git pull` from your own infrastructure
  2. Installs perl/node deps locally
  3. Runs the gulp build
  4. Runs plackup
4. Add an init script that runs that start script

This sucks, but it seems to be the way a lot of web stuff is deployed
these days.

Hope this helps,

I am the same way; I do not like shell scripts. Anything longer than 15
lines or so is written in Ruby, other than my firewall setup script.

I'm not proud of myself for suggesting what I did; just trying to
minimize your pain. Another option could be something along the lines
of:

1. ebuild installs files to `/var/musicbrainz` or wherever
2. Add a small shell script to `/var/musicbrainz` or wherever that:
  1. Installs perl/node deps locally
  2. Runs the gulp build
  3. Runs plackup
3. Add an init script that runs that start script

I guess, since you're not developing musicbrainz thingy, that the git
repo was a bit of overkill.

All these dynamic languages suffer from the fun problem that developers
that don't write enough tests have essentially no guarantee that their
code actually parses. I can't count how many times I've run Ruby,
Python, or Bash scripts only to have 'variable not found' or type
errors; all of the things that compilers do really well[1].

One of the things that results from this (IMO) is that they bundle
deps/enforce strict versions on stuff because they have to just to run
stuff. For example, a while ago www-apps/jekyll was broken because a gem
it depended on happened to be a newer version and changed the API enough
that jekyll broke. To be fair to the Gentoo developers, jekyll is
~amd64, so I didn't really care.

Alec

[1] For example, below are two *valid* files; one Python, one Ruby. Both

  puts 'hey'
end

if False:

Hmm... I don't keep up with LibreOffice development, but I have been

Not necessarily - dev-libs/check is for unit testing. It's not a direct

This might be a bad suggestion, but if you have a lot of time, it might
be easier to uninstall audacity and any other packages that have been
giving you problems, then `emerge -uDN --with-bdeps=y @world`, then
`emerge --depclean', and then install all the stuff you need.

I believe someone else mentioned checking /var/lib/portage/world and
making sure that it doesn't contain any virtuals - it might also be good
to remove from it any software that you do not directly need.

OK. Maybe we all got off on the wrong foot here. When you ask for help,

It looks like you're running Gentoo Hardened. It looks like (from a
cursory read of https://wiki.gentoo.org/wiki/Hardened/PaX_Quickstart)
that your filesystem may not support extended attributes. What type of
filesystem is /var/tmp mounted on?

Other info like the output of `emerge --info', what kernel you're
running, and what profile you're on would be helpful.

I personally do not run Hardened, so take this with a grain of salt.

This means that it installs /bin/poweroff, /bin/reboot, etc. and the
relevant manpages. I'm pretty sure that's all it does.

It is not needed at all, as long as you don't mind typing `systemctl
poweroff' instead of `poweroff', and so on and so forth. I guess the
/bin/init symlink would be helpful so that you don't have to add
`init=/usr/lib/systemd/systemd' to the kernel commandline, but whatever.

 What is it looking for?

It looks like webapp-config is not compatible with python 3.4. As far as
I can tell, here's what's going on:

 sys-apps/portage[python_targets_python2_7(-)?,python_targets_python3_3(-)?,-python_single_target_python2_7(-),-python_single_target_python3_3(-)]
 required by (app-admin/webapp-config-1.52-r1:0/0::gentoo, installed)

The above shows that webapp-config is pulling in portage built for
python 2.7 and 3.3.

 sys-apps/portage[python_targets_python2_7(-)?,python_targets_python3_3(-)?,python_targets_python3_4(-)?,python_targets_pypy(-)?,-python_single_target_python2_7(-),-python_single_target_python3_3(-),-python_single_target_python3_4(-),-python_single_target_pypy(-)]
 required by (app-portage/gentoolkit-0.3.0.9-r2:0/0::gentoo, installed)

This snippet shows that gentoolkit is pulling in portage built for
python 2.7, 3.3, and 3.4.

Since PYTHON_TARGETS is handled as USE flags, the incompatible sets of
USE flags collide. There are a couple of solutions:

* Set PYTHON_TARGETS=python2_7 python3_3
* Unset PYTHON_TARGETS and let it have its default value (which is the
  above
* Uninstall webapp-config or upgrade to the unstable version, which
  appears to support python 3.4

This is not a problem related to ncurses - just warnings that gcc
printed during the compile process that developers should actually pay
attention to and fix.
