Yup. The biggest attraction to Gentoo is that you can configure every aspect of your software builds to fit your hardware and needs.

Sure, Gentoo is incredibly malleable and a running Gentoo machine can fly through compute-intensive workloads thanks to CPU-specific optimizations not otherwise possible (ever wanted every app to use AVX instructions?) but it's too complicated for me to manage. My servers run openSUSE.

WHATEVER Dave

you can do that with every distro

esp if you're a cli guy like me

arda

@bwDraco in that case, ubuntu it is.

Journeyman Geek

@djsmiley2k I used linux entirely for ages

bwDraco

Sure, but Gentoo provides automation for compiling and updating packages.

WHATEVER Dave

you dont learn anything that way draco

in fact, having default configuration files installed for everything just spells a huge mess

brb conf call

lol

djsmiley2k

You don't need to tho

it just helps in those weird edge cases

WHATEVER Dave

id rather ./configure --prefix /usr --whatever

djsmiley2k

I use gentoo, to learn what I'm doing

WHATEVER Dave

and make make install

djsmiley2k

ubuntu goes 'oh this works, if it doesn't use sudo'

djsmiley2k

that's not learning, you might as well run everything as root.

WHATEVER Dave

^^^^

bwDraco

I've compiled programs from source on both Linux and Windows.

djsmiley2k

If you want to learn and control every little detail, LSF.

err LFS

Journeyman Geek

@djsmiley2k @WHATEVERDave I disagree

bwDraco

2:04 PM

Tried that; unexpected technical issues got in the way. Never really got to trying again.

WHATEVER Dave

sigh

i understand the dependency madness when you're wanting to patch existing services that may use specific vulnerable libraries that need to be updated

Journeyman Geek

I tend to prefer non source based distros cause its a lot easier to have consistant builds

which is why they're used

WHATEVER Dave

but thats why you keep your sources and their state in a /usrc/src

and which is why that src folder exists

incase if u were wondering

djsmiley2k

@JourneymanGeek but you can't even build debian, on debian...

hardly consistant.

/me shrugs

Unless you mean something else...

Journeyman Geek

@djsmiley2k sure you can, but why would you want to?

2016-10-26 15:08:58 Server unexpectedly closed network connection

Journeyman Geek

I can take a debian install, install the same packages, and it works the same way

djsmiley2k

@JourneymanGeek because you need some package that debian doesn't provide?

Journeyman Geek

@djsmiley2k which is relatively rare

and you can build just what you need

djsmiley2k

It takes me about 2 hours to get a gentoo build up and running...

I get a fully working toolchain, built on my current system, that lets me build anything

Anyway, I prefer gentoo, that's all.

SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.1 << :O i got this far

Journeyman Geek

that's fine

but I don't see "source based" and "package based" intrinsically better or worse

> worst

:P

Coworker/trainee/minion-of-sorts is complaining about lack of kerning on markdown.

Designers... Sigh ;p

markdown is not a layout language

Updating this answer:

A: In Prime95, why do small FFTs generate the most heat, despite CPU at 100% for all options?

Vectorized code, especially AVX, naturally increases CPU heat output because more of the processor must be used at a time to quickly produce a result. Small FFTs demand less memory than the blend mode, so the processor spends more time processing data and less time waiting for data. The x86-64 ...

So, it seems I may not be completely correct.

Apparently, a Vcore boost is needed for AVX instructions. Why?

XKCD

That's actually the original Japanese version of A Million Random Digits, which is much better than the American remake the book was based on.

bwDraco

> Intel AVX is designed to achieve higher throughput for certain integer and floating-point operations. Using these instructions may cause processors to operate at less than the marked TDP frequency. These reductions in frequency occur because high-power AVX instructions require additional voltage and electrical current.

New ticket asking for IE support on our (ugh) "portal".

They had asked it already one year ago, but it got postponed ~~because our dev team is basically one man and occasinally two~~ for a lack of resources.

I showed them gs statistics for Brazil, they countered with analytics stats.

Apparently 6% IE9 usage was a big enough number.

Now they want IE11. I'll present current gs stats (1.64%, srsly?)

And I know for a fact they lost access to google analytics ("wait, who has the password for that again? what was the account? is it on the shared excel spreadsheet?")
