<Fallenou>
whitequark: were there a lot of assholes like me who did the log2 ? :)
<whitequark>
Fallenou: two, currently
<Fallenou>
sorry about that =)
<Fallenou>
so you are happy with your asus laptop ?
<Fallenou>
I bought the UX31A for my mother, she likes it, but she's not a developer/hacker
<whitequark>
Fallenou: I am
<whitequark>
high-DPI display is amazing, 18G of RAM and nice i7 are good for compilation
<Fallenou>
I imagine you hesitated (or at least thought about) with Lenovo stuff?
<Fallenou>
yes the screen is really good :)
<Fallenou>
IPS full HD
<whitequark>
yup
<whitequark>
I only have mostly one complaint
<whitequark>
the ACPI is really damn bad
<Fallenou>
oh
<whitequark>
race conditions, unsupported features, etc.
<Fallenou>
What OS are you using?
<whitequark>
(races) for example, if you unplug the laptop while it's in S3 and then wake it up, it wakes up and immediately receives another "lid closed" event
<Fallenou>
aouch
<whitequark>
Debian with recent kernels
<whitequark>
3.8-rc currently
<Fallenou>
ok
<whitequark>
however power saving doesn't suffer and discrete GPU works really well
<whitequark>
so it's still worth the fuss
<Fallenou>
is the switch between Intel GPU and NVIDIA one working with Linux?
<whitequark>
the controller used to not wake up when there was no AC power
<Fallenou>
wait, you were saying, yours has 18 GB of RAM??
<whitequark>
echo on >/sys/bus/pci/devices/0000:00:14.0/power/control
<whitequark>
Fallenou: yes
<Fallenou>
I didn't know they had this kind of choice :)
<whitequark>
oh, not 18
<whitequark>
10
<whitequark>
18 is theoretical maximum
<Fallenou>
10 GB, that's rare in customer market
<whitequark>
when there will be 16GB on a single board
<whitequark>
Fallenou: it wasn't out of the box
<Fallenou>
oh ok
<whitequark>
they have 2GB soldered on the MB
<Fallenou>
arg
<whitequark>
and another 2GB (I think) on a board
<whitequark>
or 4GB
<Fallenou>
on UX31A it's soldered as well
<whitequark>
I installed 8GB
<Fallenou>
is the dual channel still working well?
<Fallenou>
sorry for all the questions, but currently I have a macbookpro and I may in maybe one year buy another laptop, I wonder if it will be a Lenovo or Asus or maybe something else
<whitequark>
how do I check?
<whitequark>
well, it boots :)
<Fallenou>
I don't really know how to check
<whitequark>
I never really understood the dual-channel thingy
<Fallenou>
but I just know that if a few requirements are not OK dual channel is not working and you lose in memory bandwidth
<whitequark>
plus, I don't think any of my workloads have memory bandwidth as a bottleneck
<Fallenou>
like "not having the same amount of ram in the two channels"
<Fallenou>
etc
<whitequark>
either CPU or I/O
<Fallenou>
yes its usually blury to understand what are the REAL requirements of dual channel
<whitequark>
youre going to try *really* hard to bump into memory bandwidth, no?
<Fallenou>
no I'm just asking, I have no plan or precise use case
<Fallenou>
usual use cases for me are checking emails, IRC, twitter, compiling toolchains and kernels
<Fallenou>
and sometimes FPGA synthesis

I think you're fine with UX32VD for all of the above
<whitequark>
with maybe 8GB stick for Xilinx ISE
<whitequark>
it should also get cheaper now...
<Fallenou>
my desktop computer handles well Xilinx ISE stuff with 8 GB
