Re: [gentoo-user] USB mouse disconnecting

[R0b0t1]

The most likely cause is a poor electrical connection. How quickly
they wear depends on the types of devices you buy as well as your
ports.

The reason it seems like an electrical problem is the descriptor read
errors. If it was power management the device should cleanly cycle.

[gentoo-user] Re: Thank you for your insight.

[R0b0t1]

Thank you for the response, though I feel you don't address my
question. Happily though, I spoke with an acquaintance and it was
determined that the subservience to the license (i.e. agreeing to be
bound by the GPL2) could not be offered as consideration as its
restrictions were not the licensee's to offer at the time of
acceptance of the license. The licensee had no rights to offer as part
of the contract, as the contract had not yet given them any rights to
give up. The terms put forth by the GPL2 are only restrictions that
are part of the license.

Furthermore, as stated above, it should seem quite self referential -
I can't offer my acceptance of a license as consideration, because it
is what I am trying to accept.

As I am sure you are aware, under US law there is no contract if both
sides have not provided consideration. This leaves us in the strange
place of gratis licenses being suggestions.

Apologize for the follow up:

Not being able to rescind the license is like saying someone who was
lent a lawnmower gets to keep it indefinitely with no contest because
the person who lent it can't rescind the grant to the lawnmower.

This was cross posted so many places I have to preface: I got here
from the Gentoo list. If this only makes it to the crossposter forward
or follow up on the information as you see fit.

The post is crass but still has technical merit. More importantly he
seems to be right, the idea that the grantees can't rescind their
grant is pretty strange. I'm allowed to change my mind, and you have
no claim to my labor if you didn't pay for it, nor can you make me
work for free.

There is one thing you get for free (that you probably had anyway):

I was seeing whether or not the disclaimer of liability in most FOSS
licenses was valid. They may not be, *especially* in those United
States which require a guarantee of merchantability or suitability for
a particular purpose.

Read: You made it, you claim it does something, and if someone uses it
and it *doesn't* do that thing explosively it's still your fault even
if it was free. The amount of damages are definitely tempered by the
fact it was free. Depending on the license, state, and judge, you
could have given consideration even though you did not pay money.

I think it is important to clarify that it can be requested you stop
distributing the work or stop using it for some commercial purpose,
but there is no way you could e.g. be forced to delete copies of it
you already have.

Also: Consideration can be nonmonetary, can you speak to this?

It depends why it is up for removal. Fix that issue and submit a pull
requests via GitHub or via email to gentoo-dev. If using gentoo-dev
there is the possibility that it will never be allowed through the
filter, so perhaps ask about it on IRC as well.

In the rare chance that the package is just being removed because it's
old, making gentoo-dev aware that you use it should be enough.
Otherwise bump the version.

Plasma has some rough patches but the code quality is a lot better
than previous KDE frameworks. It improves regularly, so please keep
complaints current.

I do understand though - it has gotten a bit less stable since I last
tried it, but I think it is time to try it again. For my daily driver
I tend to use i3 though.

I suspect why he posted it is at least a few developers do not want
this to happen. Other large projects have had similar turmoil, but
there is usually no remedy if you disagree.

E.g. Django(?) had a large patch committed that changed the names of
master/slave to something else as the terms were considered abusive by
what looks to be a minority.

If you had not heard of it elsewhere the Linux code of conduct was
amended. It makes the CoC similar to those of other projects where
there are a number of (usually nontechnical) contributors who identify
as a champion of social justice.

The second link is not horrible, but I think is badly formatted. Here
is a picture for you:
https://4bds6hergc-flywheel.netdna-ssl.com/wp-content/uploads/2018/09/croraline-meritocracy.jpg.

The last link is actually very informative. I would recommend reading
it. Some contributors have apparently threatened to revoke the license
to their code which is now in Linux.

My personal opinion is that generally these CoC documents do not do
what they set out to do. Even without a contributor agreement people
can be and are ejected from projects for any reason. However, the
particular entourage that follows these CoCs can be harmful for a
community due to the regularity they find offense with other people.
You find under the "SJW" label people who think a man accused of rape
has no legal rights, etc... So CoC violations tend to devolve into
witchhunts.


My personal experience was that I was not really able to go to school
because of my gender. I am male. I had female classmates with worse
grades than I did that had school completely paid for due to
scholarships. If I tried to say this to some people they would blow up
in my face because of my race and gender, but would claim they are not
racist or sexist.

It is fine to say not everyone is like that, but trying to divorce a
movement from its most vocal subgroups is the

This is where it gets a bit weird... It seems there are multiple
custom remote debug implementations.

Microsoft uses https://github.com/Microsoft/ptvsd. Visual Studio Code
is actually quite good and should run on Gentoo - it is open source,
as is their remote python debugger. I had forgotten about it but if

Yes. For all interested there is a .jar going around that has been
modified to avoid the license check that is as far as I can tell safe;
it does not require a network connection.

There is also PyDev, based on Eclipse. Remote debug (which entails
running) can be found documented at
http://www.pydev.org/manual_adv_remote_debugger.html.

Usually what I see is either sftp or rsync (over ssh) to the remote
computer, then ssh to run the updated files. Alternatively you can ssh
to the remote host and run vim within that session.

Re: [gentoo-user] Anyone using gentoo on POWER?

[R0b0t1]

Availability is okay. As long as you're not trying to run a prefix
installation from AIX a almost everything should work out of the box.
Programs that are heavily optimized may fail due to lack of code paths for
POWER8/9 but that is fairly rare.

Toolchain problems are most common.

You might mess with the below. Is there a seconds field? It doesn't
quite work, potentially due to the missing info. It still seems too
far off. Run with list as first argument.

EXIF data may work, but I'd be worried the same mistake was made,
assuming the people who wrote the camera software messed with the
drivers.

The high order bits are incrementing too quickly. I will check in a

Can you not run Steam in a VM or container? Distributed binaries on
Linux being pinned to old library versions has always been an issue.
There was a period of time roughly 1.5yr ago where people were
claiming Valve/Steam/developers had learned better (I attribute this
instead to Ubuntu starting to maintain more recent libraries) but it
seems like everything is broken again.

It looks like the errors you posted are exactly this issue, and this
is the one way to fix it forever. In my case I wouldn't trust Steam on
my main system anyway and would have to run it in a VM.

I experienced these lockups using Plasma without Nouveau (in a VM,

Have a look at GNOME/Ubuntu's onboard. It seems to have gotten some

You can also try adjusting the display properties of the different

What are you trying to do? Find the command being run and run it
manually while specifying --keyserver. Also file a bug report.

I posted my last reply after pgp.mit.edu also failed. The URL you give
is obviously a key server pool, but it looks like MIT's may be also
(without inspecting it). I retried on MIT's URL until the request went
through. If you can't change the URL then keep trying.

The issue is, I think, that the pool will give you servers that don't
support HKP, but I have had this issue when contacting keyservers
directly.

I'm getting the same thing. Also with pgp.mit.edu. Is there any fix?
The webrsync-gpg keys have expired, and the documentation says that
`gpg --homedir /var/lib/gentoo/gkeys/keyrings/gentoo/release

How did you install the bootloader? Is your board switched to legacy
mode if that is what you are using? If using UEFI do you have both
BIOS and UEFI boot flags set?

The error you gave is what the motherboard firmware would display if
it can't find any bootable drives. Some firmware (like Apple's) will
only boot a UEFI partition if the enclosing protective MBR also has
the partition marked as bootable.

It is my understanding release engineering maintains separate keys
explicitly to prevent situations like this from getting worse.

But, the same machine which was compromised (if a machine was
compromised) likely had commit signing keys. Considering the size of
Gentoo I think GitHub would respond to a request for information on
who added the malicious account to the project if that information is
not already available.


Considering what was done it could be assumed that no access to the
master repository was available. If so, any change pushed to the
mirror might have been far easier to notice and the attacker could
have considered their GitHub access worthless.

I'm not sure the above is a reasonable assessment; someone likely just
burned access easily worth multiple millions of dollars in CPU time.
Other infrastructure should be under scrutiny for past exploitation.

Can you SSH into it at all via some other interface? Can you ping it?
Try g_multi so that you can have a serial terminal to log in with. If
possible switch to using g_ffs. I have included a script at the end of
my message which will create both CM and ACM (serial) endpoints.


On the device, bring up the interface and give a fixed static IP to
the interface. A route should be created but if not route everything
on that subnet through the gadget ethernet device.

On the host, bring up the interface and give a fixed static IP to the
interface. A route should be created but if not route everything on
that subnet through the gadget ethernet device.

It may be necessary to bring up the device first.

> What modules do I need loaded exactlu on the PC

If usbX shows up and is renamed then you have the proper driver
loaded. There should be a message labelled "cdc_XXX." By default
g_ether should use CDC ECM (Ethernet control model), but it is also
possible to use CDC EEM (Ethernet emulation model), CDC NCM (network
control model), or RNDIS (remote network driver interface
specification, Windows).

Of the protocols ECM is the simplest, and in theory should have the
worst throughput do to inefficiency when wrapping Ethernet frames.
However in my tests it had the highest throughput by a few Mb/s
(~90Mbit). EEM and NCM were tied (88Mbit) though NCM is the newest and
may eventually surpass the others. RNDIS was slower by 10-15Mb/s
(70Mbit) and a full specification does not exist. However, it may be
necessary if you wish to easily use your device with Windows machines.

You need to run it on the computer you wish to connect to.

Note that if you think RDPWrap is illegal then using the remote
assistance tool in this way would *also* be illegal.

What did you expect it to do? Did you read the README? I recommend the
zip file. From it you need to run install.bat. A window will pop up
and should say the install has completed properly. Afterwards you can
connect multiple times to your computer over RDP.

If you think there was an error take a picture. I've never used the
MSI. If you used the MSI it may have silently succeeded.

There are three ways I could see solving this, in order of ease of use:

1) Use RDPWrap.[1] You click some buttons and then connecting via RDP
with multiple users will not kick out your previously logged in
session.[2] To make things easier to manage I'd recommend creating a
separate account to run your VMs so that you can leave it on in the
background. However, there is a setting in the RDPWrap configuration
tool to allow multilogon with one user which you can try.

2) Use X2Go. Use the "suspend session" and "reconnect to session"
features. To use this you need to connect via X2Go to create a session
and then disconnect while leaving it active. You can later reconnect
at any time. This can be a little strange when accessing the session
locally, as you need to log in and then reconnect to the session on
the same computer.

3) Use X11 forwarding. This is likely to do what you have requested
but requires some minimal application support. If you launch a
forwarded application it will exit once it is closed on your desktop.
However, any daemonized programs you are running will stay active, and
the application you launch with Xming could be e.g. a managment
interface to that server.

4) Use VNC. This is probably the worst option but will do *exactly*
what you have requested. It will fight the user for the mouse if they
were sitting in front of the computer.

Can you comment on your evaluation of the suitability of some of the
other options?

Cheers,
 R0b0t1


[1]: Most users do not consider RDPWrap to be against Microsoft's
terms of use. I would feel comfortable using it in a corporate setting
(there is in fact a company that sells a product nearly identical to
RDPWrap). An in-depth discussion can be seen at
https://github.com/stascorp/rdpwrap/issues/26.

Perhaps the most limiting interpretation of the license that is still
reasonable allows you, the licensed user, to connect as many times as
you want to a single licensed installation:

Section 2.d(ⅴ): “Remote access. No more than once every 90 days, you
may designate a single user who physically uses the licensed device as
the licensed user. The licensed user may access the licensed device
from another device using remote access technologies.”

And in fact this is what I expected a Windows 8.1 Pro license to grant
me the ability to do out of the box, yet it does not without minor
modification.


Note the Windows license has some patently ridiculous things in it and
may not be valid. Taken at face value you are likely already violating
it. For example:

"Section 2.c: “[…] this license does not give you any right to, and
you may not:” and Section 2.c(ⅳ): “work around any technical
restrictions or limitations in the software;”

Ergo, "[...] using the file search utility FileLocator to work around
the restrictions Windows puts in place to limit your ability to find
files on the system is strictly speaking a violation of the Windows
license as written."


[2]: Depending on the settings you pass to RDPWrap connecting as your
user remotely while you are logged in locally will forcefully close
the local view to the sesion. This is probably what you want.

What do you mean by shadow?

There are a few options:
1) Have VirtualBox run a remote desktop server. You would connect to
VirtualBox, not the guest system.
2) RDPWrap (https://github.com/stascorp/rdpwrap) - This would allow
you to log in multiple times via Terminal Services to your local
machine. You could run VirtualBox on another account or on another
session of your normal account.
3) X2Go - This is really the best option I have used recently.
4) FreeNX - This may be defunct now, and may still depend on the
proprietary parts of NxMachine.
5) XRDP (http://www.xrdp.org/) - This is an open source Terminal
Services compatible server.
6) X forwarding - There are X servers for Windows and OSX.

I'd strongly recommend against #1. It is easy to set up at first but
becomes hard to integrate your experience between remote and local
systems. If you can spare the time I would recommend trying #4, RDP,
save its security, is actually a fairly feature-complete protocol,
supporting things like tunneling local devices to the remote machine.

Use crossdev to generate an x86_64-pc-linux-gnu (or x86) toolchain.
You can specify something in place of "pc" to identify the system and
be fairly compliant, or you can invent your own naming and specify the
architecture manually. This will create a root in /usr with the name
given that will have a make.conf in /usr/${name}/etc/portage and
generated packages in /usr/${name}/usr/portage/packages.

My apologies, sir. Sometimes I forget that the United States is not

AMD is an American company based out of California. However rereading
the post I notice he is using Euros, in which case there are likely
even stronger guarantees of fitness for a particular purpose. I
suppose it doesn't help that the seller seems to have gone bankrupt.

If at all possible avoid doing the RMA. It seems to take over a month,
time which you are not compensated for.

Federal law implies a warranty of fitness for a particular purpose*
from the seller, not the manufacturer. You can take it up with them.
The statute of limitations is 4 years. Make them deal with AMD.

If it increases with load the regulator is working properly. The
higher voltage is needed to induce a higher current slew rate, i.e.
how fast the electrons accelerate, i.e. chip frequency.

Yes - screen *can* hold everything until you hit enter and allow you
to edit the line and do wrapping clientside. Screen also handles
control codes properly.

I just tried to find the exact settings but drew a blank. It doesn't
do local line editing by default. Local editing should be okay with a
normal device but it will not work well if your board runs Linux.

It does have vim bindings. That is nice. In any case, issue persists

How do I fix this? I found
https://wiki.archlinux.org/index.php/Home_and_End_keys_not_working,
but the provided /etc/inputrc settings are on all systems. Connections
are made via ssh (network) and screen (serial). The issue seems to

connection.

The issue may be screen. If it is, what different thing do I do?

[gentoo-user] Maintaining Configurations for Many SBCs

[R0b0t1]

I know of a few deployment automation solutions. I feel partial to Rex.

The main alternative that springs to mind is doing it all in either
bash or Python.

Has anyone given thought to a problem like this? I want to avoid doing
something like Android does, where I have repositories for each board,
and then a huge repository of repositories, and everything slowly
turns into molasses.

I need to keep:
  *) U-boot configuration.
  *) Kernel configuration.
  *) Root file system or stage 3.
  *) Stage 3 configuration, a.k.a. stage 4.

I need to be able to:
  *) Compile u-boot automatically.
  *) Compile the kernel automatically.
  *) Compile the stage 3.
  *) Generate the stage 4.
  *) Generate a bootable image.
  *) Maintain the stage 4 configuration as easily as possible.

Some of these are almost entirely covered by crossdev, others are
trivial scripting tasks. The hard part is finding something that has
tied most of this together in a way that is passable already.

[gentoo-user] Globally Disable Prompt Formatting, In All Programs Everywhere For All Time

[R0b0t1]

Hello,

This has come up on this list a few times in slightly more restricted
forms. Today, I feel the need to ask about how to Globally Disable
Prompt Formatting, In All Programs Everywhere For All Time.

The issue is that over some transports, e.g. a debug serial link, with
an actual serial port, the receiving program may not be able to
interpret escape codes. Typically this is an issue when on Windows,
though PuTTY exists. On Gentoo screen will work nicely, but is a bit
heavy.

Is the only way to find every program that generates escape sequences
and disable it? What about kernel messages during boot?

A hidden service listens to connections from a Tor daemon. The
recommended setup has both on the same machine, so the web service is
only accepting connections from the machine it is run on. It does not
need to be outwardly accessible.

Tor will work even if you are behind NAT, assuming you do not run it
in a mode where it accepts Tor to Tor connections or Internet to Tor
connections.


Running a hidden service on a VPS, assuming you are not breaking the
laws in your jurisdiction, is likely the better idea. It will have
higher bandwidth and if an attacker succeeds in resolving its location
(which is possible to do and rather easy) they will get a datacenter,
not your neighborhood.

If you are breaking laws in your jurisdiction of residence I would
highly recommend moving. Whether or not it is a better idea to
self-host in this case is a tossup. On one hand, if you self-host and
the authorities resolve your hidden service's location, they get you,
but you may have a chance to destroy evidence. On the other hand, if
you VPS-host and the authorities resolve your hidden service's
location, they may subpoena the datacenter and get your details and
also the information on the server.

As far as I know it has always been like this. It may be why it was
hardly used before it came into my care. Looking at the server I could
blame poor design; the inside is rather cramped, despite the care
taken with the internal baffles. They may not have run a good flow
simulation.

Mr. Bird's observation seems to support this.

The internals are custom made to fit the motherboard, cards, and drive
slots. It may work better if I move it to another tower but it will be
a while before I can find one. I will look at the interface between
the heatsink and processor again, but it looked fine.


How concerned should I be about overheating machine check errors? I
used to think that it was best to avoid them, as the threshold was
high enough that very small parts of the die could overshoot and fail,
but I was informed that is not the case. Besides the throttling (which
is fairly bad) I am not sure if there are any drawbacks to the
overheating.

I am wondering what the point of 32 threads is if you can't use them at 100%.

The system is a few years old at this point. Old enough that the

[gentoo-user] Dell Precision Workstation Overheating

[R0b0t1]

I was compiling Gentoo, as is custom, but found my old new server to
be thermal cycling wildly. The fans will turn on full blast and
machine check errors will be generated if I use approximately more
than one third to half of the cores. The cores then throttle
themselves, only to immediately overheat once the throttle lifts. This
seems to persist on Windows, though Windows seems to be much more
conservative in its CPU usage, and triggers MCEs less.

Any suggestions? I repasted the CPU and heatsink interface, and the
machine is not loaded with dust. It was hardly ever used. The MCEs
seem to be a "normal" part of operation, though less normal on
Windows.

Is there a way to at least mimic the conservative CPU usage that
Windows exhibits?

You need to find a light color theme that works well. You should edit
your .Xdefaults (older documentation references .Xresources, which
does not seem to be parsed by some modern utilities or X11 servers) to
use that colorscheme. See the "export" tab on https://terminal.sexy/.

Pretty much every terminal should honor .Xdefaults, but if not, you
will need to change the colors in a menu.

If portage uses 256-color codes to specify an absolute color then that
should be changed, it makes the program unthemable via the standard
interface. It would also be an issue if portage used the less common
RGB color escapes.

But there is a specific HID type for "boot keyboard" which is what the
EFI or BIOS firmware looks for when starting. The report is structured
so that the firmware does not need to implement the full USB standard.
Some board firmware is not implemented properly and does not parse the
reports properly, which means some keyboards do not work with all
motherboards.

The other reason I bring this up is because reading about EFI, it
seems the system can demand boot devices are present. I have no idea
why, but what OP is seeing may be intended behavior.

[gentoo-user] [OT?] Cheap Chinese Pen Tablet (UC-Logic Derivative) Problems

[R0b0t1]

Hello list,

I can plug in a Huion H420 I recently purchased. It registers, but the
lower portion of the screen (~150px) is not able to be navigated to by
the pen. I've tried looking for bugs (some are mentioned on Ubuntu
forums) but can't figure out if any are applicable to my device or
even what they are. Enabling or disabling the proper driver doesn't
seem to change the operation of the pen tablet.

Perhaps more problematic, the tablet registers as a mouse. I don't
want it to be a mouse. Shouldn't it register as a unique HID class?
Can anyone explain how pen input works on Linux? On Windows, the pen
can do mouse actions, but it is unique and separate.

Companies which need user management tend to just set up an intranet and
provide VPN access to it which is likely not going to be a Microsoft
technology. There is no benefit to integrating OS authentication with your
transport security. If you contacted a Windows-focused business for your
administration they may set such a system up, but only because they don't
know any better.

Evaluating Microsoft software should be done extremely carefully. It is
very easy to waste time, ignoring other concerns. You may get something
working but it will not be easy to administrate or scale.

Microsoft's current revenue may be largely from customers using the sunk
cost fallacy.

You mean the same horribly insecure ciphers? The built in options are
so weak that I am not aware of anyone seriously using them; most
setups tunnel Windows technologies like RDP (which may sometimes
insist on being set up with encryption) over Linux based technologies.

I'm not sure this makes sense. Firstly, in the case of OpenVPN at
least, there is a Windows client and associated signed fake network
device drivers. Perhaps if using Wireguard you might want to connect
through a VM to your VPN; I am not sure if there is a Windows client.

Secondly - you need the VPN server to be running on a computer which
is globally accessible. If your friend is in the US or some parts of
Europe their home line may not be behind NAT, and would work if set up
properly. In general most networks you connect to will not work. You
will always need one computer which is not behind NAT.

The x86 parts are slowly going out of stock to the point where they
are expensive *when* I have found them. The TALOS 2 is the cheapest
POWER system available, but is still many thousands of dollars more
than a consumer computer (though much higher performance). ARM based
computers are not comparable in performance to common consumer
systems. Self hosting on a performant ARM processor is not a
reasonable proposition. High dollar ARM servers have closed
motherboard firmware.

Sure, if you devote all of a good salary's disposable income to a
mostly open hardware computer you can buy one. Most people don't make
that much. The bigger issue than that is all main manufacturers do not
want to remove their backdoors, and so ever so slowly, there will come
to be absolutely no choice at all, even for inordinate amounts of
money.

If it supports SR-IOV you can pass it to a guest with VFIO. If it did
not support SR-IOV it would not support VFIO.

I can't find it again, but there was a neat writeup investigating the
TCP over TCP "tunnel collapse" phenomena. When two layers are doing
the same thing, there is a tendency for both to behave poorly. I'm not
sure any deeper explanation was or can be offered, but it is something
that holds true not only for network traffic, but disk IO and
databases as well.

If I remember right it makes a huge difference in raw IO speed, but
one of the most noticeable benefits is that there are no delays as
filesystem cache is flushed to service VM IO operations (which would
be noticed outside of the VM as well).

You can pass a block device directly to QEMU, and this is recommended
for performance reasons. I have a Windows 10 VM that was passed an
entire SSD; it runs fine, and you can take the disk and plug it into
other computers. Passing a partition is a little different, if you
wish to load it directly, you would need to chainload it with GRUB, as
the MBR/GPT information would be duplicated.

All OP needs to do is pass something like "-drive
file=/dev/block,if=virtio". There should be more options, such as AIO
implementation, but you likely won't need to mess with them.

If you pass a block device the MBR/GPT information will be stored
there. In the case of passing a partition, this means you can't boot
it "directly" because the BIOS/EFI firmware can't read it.

QEMU should, by default, emulate the host processor exactly if your
machine has VT-x. The VM runs directly on the processor and all
instructions are available except the virtualization ones, but you can
enable nested VT-x or the AMD equivalent.

Hello,

I strongly recommend a Brother laser/thermal printer. They can do
color now. You can alternatively buy reservoirs for ink based
printers.

Color lasers are usually "business" instead of "home" but I would not
buy a home printer if I could afford it. The savings will be quite a
bit. A business printer will last a decade or more, and is not that
much more expensive. Someone mentioned laser getting better, I would
agree.

I haven't been able to use Gentoo directly, but I have used Linux on
Power on GCC's servers. There's nothing terribly abnormal, though
there's a lot of interesting FPU modes.

You should use ppc64le. This complicates things when compiling, and is
a minor issue for some other compilers, who do not support multilib in
a way that makes it possible to build a ppc64le toolchain from a ppc64
toolchain. You may need to set up tools on a computer of another
architecture, or get prebuilt tools from GCC.

It's a good tip, but the report seems to be a bit optimistic. Firefox
claims there are 5 processes using ~500MB each, yet if I close Firefox
10G is suddenly free. Regardless of whether or not Firefox thinks it
is using the memory, the kernel thinks it is, because OOM killer

[gentoo-user] Firefox Using 10G of RAM

Hello List,

This isn't normal. Is it due to the new process model? I think I read

unsuitable for use. Firefox will require its threads be OOM killed if
not closely monitored.

If it can be fixed - can anyone explain?

Re: [gentoo-user] Boot Gentoo live iso from grub

[R0b0t1]

I take it you have read
https://forums.gentoo.org/viewtopic-t-790015-highlight-grub2+iso.html.
This did not work for me either, and it would leave me in the same
place: the root filesystem would not be uncompressed and pivoted to.

I can't remember exactly what the change was, but I think I retrieved
the answer from that thread. Try the entry at
https://forums.gentoo.org/viewtopic-p-6348023.html#6348023, which is:

menuentry "Gentoo Linux minimal install" {
  loopback loop /boot/iso/install-amd64-minimal-20100408.iso
  linux (loop)/isolinux/gentoo root=/dev/ram0 init=/linuxrc dokeymap
looptype=squashfs loop=/image.squashfs cdroot initrd=gentoo.igz
isoboot=/boot/iso/install-amd64-minimal-20100408.iso
  initrd (loop)/isolinux/gentoo.igz
}

The difference being a change in parameter name. isoloop is now
isoboot. If that fails look at
https://forums.gentoo.org/viewtopic-p-7719674.html#7719674, but it
seems to contain the same changes.

Having read all of that again this does seem like the fix. If that
*still* doesn't work, recursively grep the unpacked ISO file for
either isoloop or isoboot to find the location in the script you
should be looking at.

You should return it, most of those components are decoupling
capacitors. Quickly switching power produces high frequency noise that
can migrate to other parts of the circuit and cause spurious logic
errors.

Pick the desktop profile with no DE. Install kde-plasma/plasma-meta
and gnome-base/gnome. There should be a drop down in your display
manager that will allow you to select which DE to launch. If your
desktop manager is associated with a DE this may be harder to find. I

Usually this will be cheaper and give you better performance. Low
quality drives are typically binned for USBHDD usage. This is changing
with the speed increase of USB3, but seems to not have entirely gone
away.

They sell SATA to USB3 *converters* that do not fully enclose the
drive. You can buy cases for the bare 2.5" HDDs if you want. You could
also look at 3.5" drives for higher storage density, though 2.5"
drives are catching up.

Just use the first result on Amazon or Newegg, or the cheapest thing
you can find at a physical store (a common brand is Startech).

I was under the impression that disabling SMP on single core systems
could lead to a performance increase, but wasn't necessary.

Is the deciding factor actually processor family? And - there are GCC
versions or distributions that have already dropped support for x86_64
processors? I'd only read about 32 bit families being dropped.

As I found explained elsewhere, what can be done with microcode
updates is actually very limited. It was claimed that most often Intel
would use updates to disable features, permanently, and could not do
much more with microcode. This agrees with my understanding of
electronics, though I originally did think that slightly more was
possible. Perhaps they could disable some cache functionality or
speculative execution, but you would still be left with the
performance penalties of most of the code-based fixes.

In any case, using my original expectations, I would not expect them
to be able to modify the behavior of the execution units in such a
fundamental way. If great changes are possible with microcode then
Intel's processors are actually closer to FPGAs, which I do not think
is likely, as FPGAs are very power and space inefficient.

What I think is missing is the full details of the cache behavior,

very bad indeed. I'll see if I can find the explanation involving only
