[gentoo-user] www-client/chromium-63.0.3239.132

[victor romanchuk]

just noticed new use flag in recent stable chromium ebuild:

$ quse -D jumbo-build
 local:jumbo-build:www-client/chromium: Combine source files to speed up build 
process.

setting that significantly speeds up emerge time (tried it twice; the second 
attempt had the flag set)

$ qlop -gHv -d `date +%Y-%m-%d` chromium
chromium-63.0.3239.132: Fri Jan 19 03:15:43 2018: 1 hour, 47 minutes, 28 seconds
chromium-63.0.3239.132: Fri Jan 19 06:11:06 2018: 1 hour, 16 minutes, 14 seconds
chromium: 2 times

not sure if it matters in that context, but I'm using distcc and do not have 
ccache though

Good to hear.
Thanks for letting us know.

The sed line is identical in operation to the awk one:
(1). Delete anything that's not in the range of lines from /foo/ to /bar/;
(2). Print the lines that match the range specified;
(3). Quit processing further lines of input on finding the first
occurrence of /bar/;

Switching to to "pinentry-gtk-2" solved the problem.

I always get one of those with a fan but they are getting hard to come
by.  Its vital to have enough cooling with a spinning drive.  I have
some Startech's with fans, but they seem to have discontinued them.

I got one of those (a Rosewill).  First thing I noted was it got
_really_ hot after a few minutes of use.  Hot as in highly unpleasant to
touch.  Nonetheless I kept using it, but it stopped working as USB3
after a month or two.  Still works fine as USB2, doesn't get so hot

The drive itself wasn't new, so maybe it just wasn't made for that speed?

Re: [gentoo-user] Re: USB3 external storage HD's

[mad.scientist.at.large]

just remember 3.5" drives, particularly the higher perfomance/enterprise drives 
can require well thought out cooling, this is a primary reason you just don't 
see 10k drives in desktops any more (had one in a mac, factory in 2001), in 
most machines they'll fail in months, they just need more cooling than most 
cases provide or can provide.  i have a slower 3 tera hgst(7500/7800 or there 
abouts) (now made by one of my least favorite vendor who bought the tech from 
hitachi) and in my warm apartement (health problems, it hurts less when it's 
very warm) have mild difficulty keeping it bellow 100 deg F.  the drive is in a 
cage directly behind a fan mounted to the front.  if you take old machines 
apart you'll notice some vendors putting the drive right behind a grill on the 
front, positioned vertically to expose maximum area to air flow, these are 
slower drives but still benefit from more cooling than is "traditional", i.e. 
unchanged since the 90's.

External cases rarely have significant cooling (even those with fans), the old 
usb2 externals will all cook your' drive rapidly if you do large datatransfers, 
they are only passable if doing small writes, like backing up single files, not 
large portions of another drive (or restoring either).  The "advantage" of 
laptop drives, and the reason they have become popular in servers is that they 
are designed to be low power, and to function in a difficult thermal enviroment 
(it's hard to cool a laptop).  they dissipate less power per byte stored, and 
are of course slower which may or may not matter particularly in a raid setup 
or if most of you're drives can spin down most of the time, they also usually 
pause them selves at a preset temperature until they cool down and constantly 
park.  if you boot off a laptop drive it will take a long time, or if you try 
to move lots of files.  for archiving media it's probably not a problem, for 
development work or engineering use it may drive you nuts and waste you're 
time. 

 if you're going with external drives use laptop drives, or build a JBOD with 
good cooling.  in any case, monitor drive temperatures, in my experiance 
anything above 100F is asking for a short life, bellow or at 100F drives new 
and old are happy for over a decade which seems like a long time, but most of 
us have data on older machines with older drives somewhere in the house and 
most don't back that up or back it up often enough.  also note that most usb 
adapters don't even allow smart access, so the only way to see if the drive's 
hot is to feel the enclosure which is not terribly accurate or usefull.  it's 
also really nice to be able to run smart diagnostics and have the os monitor 
the smart status which most versions of linux will do, don't know about 
winblows, haven't run that since xp.

Buy a SATA to USB3 enclosure and a 2.5" laptop drive separately.
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).

Good to know! Thanks.

For Spectre, GCC 7.3 is needed, which isn't released yet, but AFAIK is 
being fast-tracked for release by upstream. There's plans to backport to 
GCC 6 as well.

Thanks for reply.
I've already figure it out.  The configuration file in ccd/ directory on
a server is linked to a key generated for the client during setup on
server:
./easyrsa build-client-full syscon7 nopass   (this is client key pair)

So the file in ccd/ (on server) has to be called "syscon7" and the
client computer will take IP from this file (that you assign).

Two things to check:

First, the client configuration directory needs to be specified in the
server configuration file with the "client-config-dir" directive. In
your case, it looks like you need

  client-config-dir ccd

but try an absolute path if that doesn't work for you.

The second is the naming convention for the client configuration files
themselves. The files in "ccd" need to match the common names on the
certificates of your clients exactly, IIRC. So instead of "client.file",
you probably want just "client".
