ideas about how to reduce RAM & improve speed in trying to use lapply(strsplit())
hi all,
I'm full of questions today :). Thanks in advance for your help!
Here's the problem:
x <- c('18x.6','12x.9','302x.3')
I want to get a vector that is c('18x','12x','302x')
This is easily done using this code:
unlist(lapply(strsplit(x,".",fixed=TRUE),function(x) x[1]))
So far so good. The problem is that x is a vector of length 132e6.
When I run the abov...

Dear All,
I just implemented a (6x(4+2)) DISTRIBUTED DISPERSED gluster (v.3.10) volume based on the following hardware:

Now, we need to add 3 new servers with the same hardware configuration respecting the current volume topology.
If I'm right, we will obtain a DITRIBUTED DISPERSED gluster volume with 12 subvolumes, each volume will contain (4+2) bricks, that is a [12x(4+2)] volume.
My question is: in the current volume configuration, only 2 bricks per subvolume or one host could be down without losing data. What it will happen in the next configuration? How many hosts could be down without losing data?
Thank you very much.

More than 2TB RAID...
Hi,
I just received a new server (HP DL180G5) with 12x 1TB HDs and I bumped into fdisks 2TB limits...
Since this is an entry level server, I can't use the classic HP bootable utilities to create smaller volumes et can only create a big RAID6.
I found out that: using parted, labelling it gpt and creating the partitions would do the trick.
But, what...

CentOS 8 partiitioning for reliability
I was just given a Dell R720xd with 160 GB memory and 12x 900 GB drives
that I plan to deploy as my home mail/file/backup server to replace an
aging Supermicro server running CentOS 7. Yeah, it's gross overkill for
that and I expect to tuck most of the drives away for spares.
How should I RAID and partition this beast for maximum reliability?

So, you?re already 12x higher than his budget, and it?ll be going up 20% in early April.
On top of that, there?s certainly a transfer rate limit. I couldn?t find a reliable source saying what that limit is, but I found a related limit for G Suite here:

[PATCH] added key bindings for window raise/lower
Hi all,
Did a pretty simple patch to allow raising/lowering window using key
bindings, which I personally use a lot in other window managers.
As simple as it is, it changes the size of the _CompDisplay so we
probably need to bump up the abi version if this is accepted?
Thanks.

[LLVMdev] Performance vs other VMs
...ron and I have published the results here:
http://flyingfrogblog.blogspot.com/2009/01/mono-22.html
The LLVM results were generated using llvm-gcc 4.2.1 on the C version of
SciMark2 with the following command-line options:
llvm-gcc -Wall -lm -O2 -funroll-loops *.c -o scimark2
Mono was up to 12x slower than LLVM before and is now only 2.2x slower on
average. Interestingly, the JVM scores slightly higher than LLVM on this
benchmark on average and beats LLVM on two of the five individual tests.
The individual scores are particularly enlightening. Specifically:

The end result I'm trying to get to is encoding a single 16kHz 16-bit LPCM
channel to fit into ~60kbps, and I'd like to encode in real-time or
better. The opus_demo compression with default setting is fantastic on my
test audio - more than 12x, where I only need about 4x. Hopefully that
means I have plenty of room to tweak so I can fit it in my limited
resources.

Simplifying similiar sip trunks
...sip trunks that are very similiar, like extension 412 below.
Is there any way to have a single variable in [general] that contains
the 7 lines after 'username=412'? This would reduce clutter in sip.conf.
I don't want to put these common lines in [general].
What I have now repeated 12x:
[412]
username=412

canreinvite=no
nat=no
I'd like something in [general] like:

Many thanks in advance.

P.S. The performance improvement is amazing - anywhere from 2X to 12X
depending on what metrics you are looking at. It isn't an apples to
apples comparison since we upgraded the servers as well but the "old"
servers are pretty powerful beasts.

15% or more.
