What kind of latency are you expecting to get with Gentoo running on CoreOS? A process inside a container is no different from a process outside a container as far as anything other than access/visibility goes. They're just processes as far as the kernel is concerned. Sure, it isn't quite booting with init=myscieneapp but it is about as close as you'll get to that. I'm not planning on running gentoo on CoreOS; so apologies if that is confusing. I'm intending on running a stripped and optimized gentoo OS and linux kernel as close to bare metal as I can. gcc5 is targeted at both system, GPU and distributed resource compiling (RDMA). Mesos + spark + tachyon + storm + RDMA + GCC-5.x is a killer platform for clustering. It supports some traditional and well as radical frameworks. Mesos is exploding with new Frameworks and is planning on support for many languages. There is a bgo on apache-spark that needs a really talented Java Hack to solve. There is also an upcoming mesos conference in Ireland [1] that any Euro_hack interested in Clustering should attend. Many companies are hiring talent and paying a 50% premium, particularly if you can admin, code and compile and know a bit of basic clustering.

When gcc segfaults, it is always suspicious mostly because the compiler is an app where we know the devs take extraordinary measures to prevent it. The most common cause is faulty hardware (most often memory) as gcc tends to use all of it in ways no other app does. The usual procedure at this point is to run memtest for an extended period - say 48 hours, or even 72 for an older slow machine. That is definitely good advice. I've run into this situation several times. A machine had bad RAM that didn't seem to cause any problems under normal operation. But, when trying to compile something large like gcc, I would see non-repeatable segfaults (it wouldn't always segfault at the exact same point). In those cases, I could often run memtest for several passes and not see an error. But, _eventually_ ramtest would catch it. Run memtest for a few days. Really. -- Grant Edwards grant.b.edwardsYow!

So this is to create a installer then? Someone built a installer a long time ago and it didn't work well. Heck, I never could get the thing to even complete the install and that was IF it would boot at all to even start the process. It would hang somewhere and then sit there doing nothing. After that, I found a installer to be useless and a waste of time. I wasn't alone on that point either. Not long after that, the installer project died. The current handbook, it works. Funny. I just recently took the old 2008 version and installed on old vintage hardware and it worked like a charm. ymmv. This is the issue as I see it. A few people want a installer to make Gentoo easier to install. Well, why? After you install Gentoo, you have to update, maintain and maybe repair that install. A installer isn't going to do that unless you wait for a new version of the installer and re-install/update sort of like windoze does. Basically, you are going to need what is learned during the install to maintain/repair your system and that is just the start of it. It's that simple. I look at your argument here as mono-dimensional as there are a plethora of 'gentoo' systems one can end up with now; a lot has changed. Embedded, tablet, gentoo-cell phone, efi, mbr not to mention what the final target is (server, security-appliance, terminal server, CI, vm or container host etc etc). One install semantic does not fit all current nor future needs. Besides, if I want to deploy 50 systems for a cluster, one at a time in parallel what do you recommend? via handbook? The modern diversity of hardware options has rendered the gentoo handbook, dysfunctional, at best, imho. ymmv. Another issue with having an installer. People install Gentoo with the installer, if it works, and are basically completely clueless about Gentoo and the effort it takes to run it. I'd be surprised if even a small percentage that used the last installer are still using Gentoo. I am; that's at least one. People use the installer, find out that Gentoo isn't a point n click distro, get pissed because they actually have to work at it and then they switch to something else. Does that benefit Gentoo? Not likely. So we split off the install support to another group so the good-folks on gentoo-user do not have to be bothered with these sort of installer-folks. My bet is this *attitude* is bullshit and these problems, with an automated install system will be quite manageable by the gentoo-noob-community directly. ymmv. We'll see, won't we? Either way, your participate will be optional; so don't stress out about it. Gentoo can be a pain and most people don't want that because they don't want to put any real effort into their OS. When I install Linux for someone else, I put some sort of Ubuntu or something that they can handle. Putting Gentoo on a system and expecting them to handle updates would be . . . well . . . silly. It would be a setup for failure. If someone wanted to run Gentoo on their puter, I'd sit with them while they went through the install, with them doing the work and learning. Dale, kids, old folk and such blue collar folks run gentoo. I know I have set up probably hundreds of gentoo systems for folks over the years. Many haver gone on to study computer science or EE in school, other keep busting wrenches for a living. The mystic that gentoo is only for the compiler genies of the world is absolutely bullshit, so get that out of your brain, or at least stop spewing that venom as gospel. You have no statistical proof, only one at a time experiences. YES some behave that way. But countless others do not and have not behave that way in the past and currently; and they would appreciate a simple semi-automated install pathway, if not many such options for unattended installs of gentoo. To me, gentoo is an emancipation of one's ablity, to both run and optimize software on hardware or virtual; and I run into lots of folks, including recent college grads that just love it. Gentoo is NOT DIFFICULT, once the basic install is accomplished, in my experiences. A frustrating gentoo install does not even come close to learing everything one needs to know about gentoo to manipulated the gentoo system going forward. Nor is it the only pathway to a happy gentoo install. Embedded software developers that have little *nix experience readily take to gentoo, because of it's sourcecode nature. There are many of those folks being force into linux in the past and currently. Many of them are older and some have lots of experience with assembler codes. All that I have dealt with are bit agry that somebody did not tell them about

A windows user??? Well, let's see. It's not like Nepomuk and the concept of a semantic desktop wasn't a university research project sponsored by the European Union, and the researchers chose KDE to implement it on (presumably because OSS is an excellent fit for exactly that kind of thing). It's not like there aren't many web pages out there that fully describe the origins of Nepomuk and what the purpose of the research was, and that Google can't find all of those issues for you in mere seconds. Nope, it wasn't like that at all. The purpose and goal of Nepomuk is not in doubt, not even slightly. The first implementation though, turns out to have been less than ideal, particularly the backing store. So Nepomuk was eventually considered a flawed prototype that demonstrated what not to do (this is the *real* purpose of prototypes - ask any successful engineer), and Baloo written instead. The intent is to get the benefits of a semantic desktop without having to use all available resources to do it.

I have mixed feelings on this one.
YES. We all do. I just think the time has come for gentoo to offer
a variety of installation semantics. The hand book is valid. An installer
is valid. Using Ansible and such is valid. Clonezilla is valid [1].
Using scp or dd HD to HD is valid. There are no limits to valid
pathways. We should just get on with 'diversity of gentoo installs' and
be done with it. If the handbook is 95% of the new installs, so be it.
MY prediction is with other viable options, the handbook we be actively
used as a reference, but we'll quickly experience an increase in usage
of new install semantics. Pentoo is one well kept secret, as you know.[2]
zchaos is a titan, imho, and his work deserves accolades as well as exposure
in the greater gentoo community. I certainly appreciate pentoo
more and more every day.
After reading some accounts in a completely different list I can see a
lot of the value of just being able to click a few buttons and have
gentoo running, and then having the luxury of tailoring it later.
This was the driver to drop the stage1 installs in favor of stage3 in
the first place.
We can all interpret the past via a variety of lenses. As always your
perspectives have a causal effect on my mind, so go easy with me? I do not
have all of this worked out, but, I am very passionate about this paradigm
shift.
Bootstrapping, from a micro processor point of view, has a myriad of
semantics, all valid and millions of embedded products use bootstrapping
semantics mostly uniquely created by the coders of those individual
products. Semiconductor companies usually provide the stub code, registers,
details of ram, rom, eeprom mmc, flash, etc etc and the coders write unique
code to package the boot-loader so as to be 'license free'. WE do not have
to go to that level, but surely encouraging and creating a plethora of
pathways to install gentoo is a good thing.
Then folk can think of a variety of ways (catalyst, profile, world_file,
ansible etc etc) of how to put collections of packages and configa onto the
recent installs in an unattended fashion. This will prepare us (gentoo) to
champion the future of VM, Containers and clusters is a very logical and
extensible way. NOBODY is bridging the divide between physical (actual HD)
semantics and those ethereal {vm, container, remote hosted etc) so that it
is one large, but logical endeavour. imho. This is where I believe gentoo
can dominate. Compiling from 100% sources, the gentoo way, is a killer
advantage and gentoo is very well positioned on that. You should read up on
what D.Berk wrote some years ago about clusters and look at the who's
who list of research and commercial folks that used gentoo for clusters;
if you have not already done so. I have notice some of those docs
disappearing, but they are all at legacy archives..
Tuning clusters/Clouds is all about managing sources, keeping the
source-trees (gitignore) pristine and keeping the OS pristine. Likewise the
same thing need to happen to the underlying kernel. Like it or not the
Kernel_bloat is at an all time high and that is a separate but parallel
need. Gentoo supporting both OpenRC and systemd is allowing this distro to
morph into something unmatched in the linux world, imho. It's a very good
thing for Gentoo and I believe this will only benefit Gentoo, linux and the
open source communities. Like it or not, Gentoo is a power player. Folks
just try to keep it a secret, commercially. It's gonna explode everywhere,
once it is easy to install. Systemd has dis-lodged many linux users
and that is a wonderfui but time limited opportunity for Gentoo (a window in
time, if you like).
Combined efficiently (virtual and real), will allow the distro to prosper
beyond it's competition. Those non-rolling distros are at a huge
disadvantage on performance, security and maintainability imho. Look at
Suse's recent moves. All we lack is raw speed/simplicity in the installation
semantic(s). imho.
Still, if I were actually deploying on a cluster I don't think any of
this is the way I'd probably do it. On a cluster I'd be more
concerned with integration with a configuration management system.
I'd be thinking more of things like openstack and coreos for the
initial install, and then Gentoo is just something that goes on top
(or in the case of coreos, underneath). It is a bit like sticking
your filesystem on top of lvm - it just makes things easier down the
road with almost zero cost.
Those distros that currently offer quickie installs of clusters,
are mostly pathetic at what's needed to run different, tuned or stripped
kernsl underneath. Kernel tuning supremacy for those 'cluster distros'

After reading some accounts in a completely different list I can see a lot of the value of just being able to click a few buttons and have gentoo running, and then having the luxury of tailoring it later. This was the driver to drop the stage1 installs in favor of stage3 in the first place. Still, if I were actually deploying on a cluster I don't think any of this is the way I'd probably do it. On a cluster I'd be more concerned with integration with a configuration management system. I'd be thinking more of things like openstack and coreos for the initial install, and then Gentoo is just something that goes on top (or in the case of coreos, underneath). It is a bit like sticking your filesystem on top of lvm - it just makes things easier down the road with almost zero cost. -- Rich

If just one thing, just one tiny bit, is not working correctly, you get bad data. With computers, one bit of bad data means something doesn't work be it hard drives or memory or even the CPU. You may can live with it on widoze but not Linux. Linus maximizes the use of memory more so than windoze. I have 16Gbs of ram here. Even if I don't compile anything, eventually all my memory will be used by cache if nothing else. Once that cache hits a bad spot, there is trouble.

Re: [gentoo-user] Anyone using xfce4 with compositing turned off?
walt w41...@gmail.com wrote: I'm seeing horrible performance from the xfce window manager (xfwm4) on my main, everyday machine, but not on an older backup machine or on any of the linux virtual machines I run on virtualbox. The symptoms: moving a window with the mouse is so slow as to be painful, and the CPU usage (on one of four CPUs) jumps to 100% almost immediately (xfwm4 is the culprit, see below). I'm using XFCE as DE and xfwm4 as WM. Since I bought a new GPU (Radeon R7 250), I don't use compositing any more because it causes tearing when I watch videos in fullscreen with 3840x2160. With this GPU I also had some random freezes when compositing was enabled. Beside this, performance is very good, regardless compositing is enabled or disabled. Scrolling text or moving windows around is a bit faster and smoother with compositing enabled, especially when other windows are in the foreground. With my old GPU (Radeon HD4550) I always had compositing enabled. Everything was smoother and I saw absolutely no glitches, but performance was also good with compositing disabled, just not quite as smooth as with compositing enabled. If I open an xterm and run (for example) /usr/bin/marco --replace, this sluggish behavior returns to normal immediately. After wasting hours on google I finally noticed that I had compiled x11-wm/xfwm4 with the xcomposite useflag disabled, so I enabled it and re-emerged xfwm4. Now I can get decent performance from xfwm4, but only if first I turn on compositing by running xfwm4-tweaks-settings. (No, not by running the puny and feeble xfwm4-settings app: I need to invoke a tweak to make xfce4 an acceptable Desktop Environment on my main desktop machine. As long as I use XFCE (many years) xfwm4-tweaks-settings is the program to toggle compositing. It's just a name, what is the problem? :-) Or do you mean, that you must enable compositing every time you start XFCE? official rant mode I remember going through this same frustration with gnome3, which was (and is) unusable without installing the gnome-tweak-tool package and using it to customize settings that I still don't understand. (That's why I finally gave up on gnome3, and I may yet give up on xfce4 and go back to mate.) Note that I'm not turning off official rant mode yet, but I should mention that this machine is ~amd64 with ati-drivers-15.7 and vanilla kernel 3.14.51. (Same problem with gentoo-sources-3.18.19, BTW.) I'm using stable xf86-video-ati and stable hardened-sources. I never used ati-drivers because I don't like to have proprietary software on my gentoo box. For me xf86-video-ati works well and has a sufficient 2D and 3D performance. -- Regards wabe

It's perfectly reasonable. If it's under warranty, return it. And get a different brand cause it sounds like what you got is crap. If it's not under warranty and after running the test for an extended period as adviced you're sure that it's only a single bad bit at the highest end you can boot with the mem= option.

I used to use Kmail until all this mess started. I think the last I used Kmail was back in KDE3. When I saw all this mess coming, I switched to Seamonkey. Seamonkey does all my email stuff and I'm happy with it. I do wish the sound notification thingy would work tho. Maybe I just need to sit down one day and try to figure out why it doesn't work. Sound works everywhere else. Still, it does what I really need without to much bloat. I installed KDE with the kde-meta. It basically installs everything but the kitchen sink. To be honest tho, I could likely install it in a better way that leaves out TONS of stuff I never use. This file indexer thingy is one of the ones I have never had a need for. If I want to find some file, locate, find and etc works for those rare occasions. It is rare since I'm fairly well organized with my stuff. Well, computer files at least. My closet and shop is a different matter tho. lol My point was that this can be disabled IF it is not needed. If it is needed, then fixing it is the solution. If it is not, disable it and shove the problem into the trash can. ;-) Dale :-) :-)

The `emerge --info` helps, but you haven't listed an explicit build
