Re: [gentoo-user] Anyone using xfce4 with compositing turned off?

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.

BS needs all resources solving and supporting a single problem, with as low of latency as possible. 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). Don't get me wrong - I appreciate the desire for bare-metal performance in the high-performance computing world. I've heard stories/rumors of Gentoo getting attention elsewhere in this domain, and we have a disproportionate number of physical scientists and such in the community (including probably half of the Council - we joke about it). I've even heard of Gentoo used in high-throughput trading, though a lot of that has moved on to ASICs and such and nobody talks openly about what they're doing. I was just trying to point out that containers are very different from VMs, while generally trying to solve the same sorts of problems. VMs create continuous execution overhead and are memory-expensive. Containers have zero execution overhead and are very memory-efficient. Of course, if you throw 5x as many running processes on the same PC you're still going to consume more RAM and CPU, but 5 containers running on 1 PC tend to be pretty close to the CPU+RAM requirements of linux hosts running on 5 PCs. If you're just using containers for configuration-management/etc and just run one container on a node, then you're going to be very close to the same performance you'd get running it on bare metal. From the kernel's perspective every linux system uses containers. They just tend to use a single container. The kernel doesn't do anything differently when a process spawns in a container. When that process looks out at the world the kernel shows it everything within its namespaces. That is true whether you have one set of namespaces on the system or 50. As far as I'm aware the system calls all take just as long to run either way. Containers really are just about adding one more field to the keys in various kernel objects like processes/tasks. -- Rich

If say the 5V rail is dodgy, then the output will still be a solid 5V. What's happening is that the PSU regulator circuitry can't keep up so the output averages 5V (that's what the transformer gives out) with large amounts of high-frequency ripple superimposed. Your multimeter average's that out and displays ... 5V! When things get really bad the output may dip momentarily when load is drawn, but by that stage the PSU has been struggling for a long time already. Use an oscilloscope instead, and you see immediately what condition the output is in. /nitpick Few IT techs just happen to have an expensive oscilloscope just lying around, so a good recommendation is to replace the PSU anyway every 2 years or so - more if the thing runs hot.

[gentoo-user] 69.99 != 69.99
Hi,
I have the following in a perl script:
if ($a != $b) {
print e: '$a', t: '$b'\n;
}
That will print:
e: '69.99', t: '69.99'
When I replace != with ne (if ($a ne $a) {), it doesn't print.
Is that a bug or a feature? And if it's a feature, what's the explanation?
And how do you deal with comparisions of variables when you get randomly
either correct results or wrong ones? It's randomly because this
statement checks multiple values in the script, and 69.99 is the only
number showing up yet which isn't numerically equal to itself (but equal
to itself when compared as strings).

You can use app-text/recode as follows: # echo 'ü' | recode utf8...html uuml; Or just use the codes from: http://www.lsa.umich.edu/german/hmr/schreiben/umlaute/umlaute_ASCII_html.html Thanks, I could patch the message template accordingly, that would solve the problem :)

And how do you deal with comparisions of variables when you get randomly
either correct results or wrong ones? It's randomly because this
statement checks multiple values in the script, and 69.99 is the only
number showing up yet which isn't numerically equal to itself (but equal
to itself when compared as strings).
Computer languages have a much more exact idea of what equality means
than you do. In your head (because you are human, not silicon) you are
completely comfortable with taking 69.99 and treat8ing it as a string,
or a number, or a mostly-rounded-off floating point number.
The computer does not do it like that. To a computer, the same must be
exactly the same. Two things a little bit different are completely
different (or not equal). And perl has two different operators for
(in)equality:
!= does a numerical comparison. More on this below
ne does a string comparison. When viewed as a bunch of characters, 69.99
and 69.99 are identical.
Now, your comparisons are NOT random. They are entirely predictable, as
long as you know what is going on; you are running into floating point
numbers. And as it turns out, computers never represent these things
exactly (they are NOT integers). Even though they look identical
on-screen, in RAM they will not be (this must be so for perl to do the
print). Maybe they actually resolve to 69.99001 and 69.9900. You
see them as close-as-dammit equal, perl sees them as entirely different.
This is such as huge IT problem that many solutions have been proposed.
You get classes like BigFloat that represent a floating point as an
integer so that equality works, you can round the floats off before
comparing them, or just make the things integers.
The last one is nice: don't represent money as dollars and cents,
represent it as cents or decicents and only divide by 100 (or 1000) when
you finally get to display it.
So how to fix your problem: you are doing what you shouldn't do - trying
equality on floats. Turn them into integers, or round them off, or use
=/= instead of !=

That would add quite a lot of complexity, and the problem should either
be handled transparently, or the value should be printed as the
software/computer sees it. It is a recipe for disaster when you tell
your computer to print something but it prints something else instead.
So how to fix your problem: you are doing what you shouldn't do - trying

The underlaying storage backend for Nepomuk aka Virtuoso DB has a lot of unsolved upstream issues[2], therefore we will remove it. This means packages with build options on the old stack will drop them. Other packages which hard requiring it will be removed. If you are still using Nepomuk you can switch to Baloo by globally enable semantic-desktop and disabling nepomuk use flag in /etc/portage/make.conf or using one of the kde desktop profiles.

KDEPIM needs the semantic-desktop USE flag, or it won't work fully. As long as you only want the KMail component of KDEPim you can get away without semantic-desktop.

You can see the machine's settings in the photo clearly enough. The waveform is fairly constant, it stays in this mode most of the time but sometimes goes into a low ripple mode where the ripple falls to +/- 20mv and holds tight. The scaling indicates the upward spikes are around 0.120 volts and the downward spikes are about 0.22 volts. This __SHOULD__ be within the input tolerances of the motherboard's regulators. Regulators don't filter noise, they introduce it. Capacitors do that as somebody pointed on the other thread. So if you're on a tight budget and you have an electronics surplus store nearby you can replace all the capacitors on your mobo and PSU (except the big bulky ones on the PSU) for about $3. I would call this PSU marginal, it absolutely does power the machine but it's noise output is a bit larger than what I would prefer.

This example does not use floating point for that use negative exponents 2^-0 + 2^-1 + ... + 2^-100 != 2^-100 + ... + 2^-1 + 2^-0 In general for adding many positive floating point numbers, it is better to add the small numbers first. One more example. Assume a DECIMAL floating point machine with two digits of mantissa and say 20 digits of exponent. This machine cannot express 101 since that requires 3 digits of mantissa. Then 100 + 1 + 1 + ... + 1 (100 1s) = 100 1 + 1 + ... + 1 + 100 (100 1s) = 200 allan

I guess you can just set it to a short interval, wait for it to run, then reboot and see what happens (and let us know the result :). If you use OnCalendar with Persistent=true it should run no more than once a day though, but it'll run right away on boot if you miss it one day. If you just want to replace cron my advice is install systemd-cron, it has the advantage that it'll satisfy any dependencies on cron. If you don't want to install it you can still download it and see how they did it. -- Fernando Rodriguez

You can see the machine's settings in the photo clearly enough. The waveform is fairly constant, it stays in this mode most of the time but sometimes goes into a low ripple mode where the ripple falls to +/- 20mv and holds tight. The scaling indicates the upward spikes are around 0.120 volts and the downward spikes are about 0.22 volts. This __SHOULD__ be within the input tolerances of the motherboard's regulators. I would call this PSU marginal, it absolutely does power the machine but it's noise output is a bit larger than what I would prefer. I would call that PSU on it's last legs, and highly likely to be the root cause for the recent difficulties you've posted about and possibly more too. +100mV/-200mV is excessive Given that i'm flat on my ass broke with a foreclosure over my head, I am powerfully inclined to continue to live with the PSU the way it is now until it is no longer possible to do so. Well now you put it that way, you don't have many options other than use what you've got.

When I replace != with ne (if ($a ne $a) {), it doesn't print.
Is that a bug or a feature? And if it's a feature, what's the

!= does a numerical comparison. More on this below
ne does a string comparison. When viewed as a bunch of
characters, 69.99
and 69.99 are identical.
Now, your comparisons are NOT random. They are entirely
predictable, as
long as you know what is going on; you are running into floating
point
numbers. And as it turns out, computers never represent these
things
exactly (they are NOT integers). Even though they look identical
on-screen, in RAM they will not be (this must be so for perl to do the
print). Maybe they actually resolve to 69.99001 and
69.9900. You
see them as close-as-dammit equal, perl sees them as entirely
different.
Why can't it print the number as it is, or at least as it is compared,
like it should? If it would, one could see at once what the problem is.
Your print values are coming from the original variables. The numeric
comparison does an internal conversion to two temporary variables,
and compares those, WITHOUT affecting the original data.
This string to float conversion appears not to be deterministic, if it
converts two identical strings into two different float values, but I don't
know enough about the internals to comment any further.

That noise could be what the problem was. Just a example. A fan's bearings starts making noise. Eventually, the bearings lock up and the noise stops. Guess what, the fan has stopped too. Of course, the noise is gone now but that doesn't mean the problem is gone does it? Odds are, some component was making noise because it was under pressure or age was catching up or whatever. When the noise stopped, it had likely stopped working at all. This sounds like a capacitor to me. They will make weird noises sometimes before they fail. I used to work on TVs a lot years ago, you know, the old tube type stuff. Anyway, those caps did all sorts of weird things. Some would swell up until they were shaped like a hot air balloon or something. Some would blow out the bottom and maybe even stink real bad. I've even seen some that blew the metal can completely off and the TV is full of that sticky paper stuff, which also stinks, and the foil part. Some just smoke and make a hissing sound, then all heck breaks out in the TV. Usually it stops filtering and the rest of the TV is now getting a unfiltered DC which is about like A/C. Some components like those tubes don't like that much. They tend to revolt. FET type components, when they go, they usually go quick, with a bit of stink or smoke. Usually. Yea, I'd be looking for a new power supply. Some of those on that last link I posted aren't that expensive. Just calculate up what power you need. I tend to add at least 50% to that, for future expansion and start up power. Doubling it wouldn't hurt. It just means your P/S is running at half power most of the time. On my current P/S, it is a 650 watt unit. According to my UPS, my entire computer system pulls about 150 watts idle and about 160 to 170 when compiling the crap out of something like GCC, Libreoffice etc. Now that includes my monitor, router, modem and speakers. If I were to guess, the puter itself only pulls around 100 to 120 watts. My power supply has some overkill issues for sure. I could likely easily use a 300 watt unit but would likely replace with a 400 watt since they are more available. Technically, I could use a 200 watt if the power supply was a well built model. As it is, my power supply likely never even gets warm. Add in that it is in a Cooler Master HAF-932 case and I'm sure the fan gets bored. The key thing on power supplies. If you are going to buy cheap, buy big. Cheapos tend to overrate themselves, sometimes a LOT. If you buy a well known and well tested brand, it will likely deliver what it claims and you can pick closer to your actual ratings. Of course, that cheapo P/S will likely fail you at some point. That means risking losing a lot more than just the P/S too. It could mean a new CPU, mobo, memory and whatever else it takes with it. When cutting costs, protection is one place to do it and by the time you realize it, it's to late. I've bought cases with P/Ss built in. They get removed and disassembled for little junky projects. I mostly get heat sinks and such since most of the components aren't reliable anyway. Hope you get this fixed soon. Dale :-) :-)

And how do you deal with comparisions of variables when you get randomly
either correct results or wrong ones? It's randomly because this
statement checks multiple values in the script, and 69.99 is the only
number showing up yet which isn't numerically equal to itself (but equal
to itself when compared as strings).
Computer languages have a much more exact idea of what equality means
than you do. In your head (because you are human, not silicon) you are
completely comfortable with taking 69.99 and treat8ing it as a string,
or a number, or a mostly-rounded-off floating point number.
The computer does not do it like that. To a computer, the same must be
exactly the same. Two things a little bit different are completely
different (or not equal). And perl has two different operators for
(in)equality:
!= does a numerical comparison. More on this below
ne does a string comparison. When viewed as a bunch of characters, 69.99
and 69.99 are identical.
When the value is numerically not 69.99 but something like 69.99001,
then printing the value should print 69.99001 rather than 69.99.
perl -e 'print 1/3 . \n;' prints 0.333
perl -e 'printf(%34.32f\n, 1/3);' prints
0.1482961625624739
perl -e 'print (((1/3 == 0.333) ? equal : not equal) .

perl -e 'print (((1/3 == 0.0.1482961625624739) ? equal
: not equal) . \n);' prints Integer overflow in decimal number at

This is random, may it be predictable or not, and what's the integer here?
Now, your comparisons are NOT random. They are entirely predictable, as
long as you know what is going on; you are running into floating point
numbers. And as it turns out, computers never represent these things
exactly (they are NOT integers). Even though they look identical
on-screen, in RAM they will not be (this must be so for perl to do the
print). Maybe they actually resolve to 69.99001 and 69.9900. You
see them as close-as-dammit equal, perl sees them as entirely different.
Why can't it print the number as it is, or at least as it is compared,
like it should? If it would, one could see at once what the problem is.
I can't see your code and I don't know how you get values assigned to
those variables so I can't really give you an answer.
I can tell you that equality comparisons on floats are problematic, and
always will be due to how they are stored (double-precision floats,
inhernetly inexact). This is not a problem per se, it's a systemic
side effect of how our computers represent floats i.e. you can't fix
it as there is nothing to fix
Rob0t1's suggestion was the best, I'd forgotten that neat trick:
replace
if ($a != $b)
with
if ($a - $b = $t)
where $t is an acceptable tolerance (0.001 in your case should be OK)
This is such as huge IT problem that many solutions have been proposed.
You get classes like BigFloat that represent a floating point as an
integer so that equality works, you can round the floats off before
comparing them, or just make the things integers.
The last one is nice: don't represent money as dollars and cents,
represent it as cents or decicents and only divide by 100 (or 1000) when
you finally get to display it.
That would add quite a lot of complexity, and the problem should either
be handled transparently, or the value should be printed as the
software/computer sees it. It is a recipe for disaster when you tell
your computer to print something but it prints something else instead.
So how to fix your problem: you are doing what you shouldn't do - trying
equality on floats. Turn them into integers, or round them off, or use
=/= instead of !=
'=/=' is not an operator in perl?

(1). Use sprintf to format the numbers to a certain number of decimal

A good way to demonstrate just how problematic floats can be is to point
out that floats are banned in the linux kernel for exactly this reason.
Integers only.

The underlaying storage backend for Nepomuk aka Virtuoso DB has a lot of unsolved upstream issues[2], therefore we will remove it. This means packages with build options on the old stack will drop them. Other packages which hard requiring it will be removed. If you are still using Nepomuk you can switch to Baloo by globally enable semantic-desktop and disabling nepomuk use flag in /etc/portage/make.conf or using one of the kde desktop profiles. [1] https://www.kde.org/announcements/4.13/ [2] https://bugs.gentoo.org/buglist.cgi?quicksearch=virtuoso Therefore, I think that the nepomuk USE flag is no longer valid, although semantic-desktop is still being used. KDEPIM needs the semantic-desktop USE flag, or it won't work fully. As long as you only want the KMail component of KDEPim you can get away without semantic-desktop. So far. :-) I think that migration of data will fail, address book searches won't work, etc. I haven't looked into it at any depth TBH, but enabled USE=nepomuk semantic-desktop as it was back then for this reason.

I've heard stories/rumors of Gentoo getting attention elsewhere in this domain, and we have a disproportionate number of physical scientists and such in the community (including probably half of the Council - we joke about it). I've even heard of Gentoo used in high-throughput trading, though a lot of that has moved on to ASICs and such and nobody talks openly about what they're doing. Yep; lots of folks are putting their *nix expertise into FPGAs these days as a way to protect their Intellectual Property. Here's a prime example in the drug discovery world [1]. Trading with Gentoo:: Yep. I was hustle via a NYC head_hunter for several projects, some years back, but they would never disclose the companies. One was some wealthy individual. They wanted to emcumber me before they told me anything; not a good sign, besides I'm not too fond of NYC. The more bad stuff I told the HH about myself, the more they liked me as candidate. The pay scale was way to high for my abilities anyway... Yep:: nobody talks. lots of real wise guys in NYC. I was just trying to point out that containers are very different from VMs, while generally trying to solve the same sorts of problems. VMs create continuous execution overhead and are memory-expensive. Containers have zero execution overhead and are very memory-efficient. Of course, if you throw 5x as many running processes on the same PC you're still going to consume more RAM and CPU, but 5 containers running on 1 PC tend to be pretty close to the CPU+RAM requirements of linux hosts running on 5 PCs. If you're just using containers for configuration-management/etc and just run one container on a node, then you're going to be very close to the same performance you'd get running it on bare metal. VM are obsolete compared to containers, when you start looking closely at timing and latencies which then effects throughput. That's pretty much accepted mathematically by virtually all of the clustering devs I interact with. It does not mean VMs are dead or not useful, but they are not in the competition any more on performance driven needs. Look Rich. Believe me, when you say things I listen. It's on my to do list to evaluate CoreOS vs bare metal. Not to beat a dead horse but I do need a fully unattended install semantic to do the regression testing for routine cluster needs and my half baked ideas I do not believe regression test results in vm or container setups. Maybe the first or second digit of accuracy. I'm old school and I have to isolate things on hardware. That's just how I roll:: I guess it's the EE in me. Trust but verify.. So yes at some point I intend to vet the CoreOS thing, as it is very close to gentoo with ebuilds and such I think I'm the one that pointed coreos out on the gentoo user list; some time ago, as a derivative or rip-off of gentoo. Folks said ChromeOS was from Gentoo and CoreOS was from ChromeOS (ring any bells?). From the kernel's perspective every linux system uses containers. They just tend to use a single container. The kernel doesn't do anything differently when a process spawns in a container. When that process looks out at the world the kernel shows it everything within its namespaces. That is true whether you have one set of namespaces on the system or 50. As far as I'm aware the system calls all take just as long to run either way. Containers really are just about adding one more field to the keys in various kernel objects like processes/tasks. WE have kernel shark (via trace-cmd) now and heaptrack too. Those (2) tools alone should let you gather actual data on what you have stated above and publish it. If you want a bunch of links to kernel shark info and examples just let me know. What would be keen (and is on my todo list) is to take kernelshark and use it for some deep analysis work on gentoo. Then publish a gentoo wiki page on KernelShark so the community can see a cool example on Gentoo. Kernelshark bridges that kernel/OS barrier and can quantify the actual timing and latencies and problems in a full stack or particular layer of the stack. It is addicting and can consume days of your time, just so you know (in advance). On another note:: What I'm missing (and it's definitely new learning material to me) is a robust, flexible DAG tool(s). What do you know about for DAG and such tools/codes?

OP, maybe you should give this site a look see: http://www.jonnyguru.com/modules.php?name=NDReviewsop=Review_Catrecatnum=13 This one just reviewed had a perfect score, if it has enough power for what you are running. http://www.jonnyguru.com/modules.php?name=NDReviewsop=Review_Catrecatnum=13 This site below lists them by wattage. They test them pretty hard too. If it isn't a well built unit, they'll find the problem. http://www.overclockers.com/forums/showthread.php/589708-Recommended-PSU-s-True-Tested Hope one of those helps or maybe all of them.
