I'm working with Xen for the first time, using Alpine Linux as Dom0.
I'm following the Alpine Linux guide to set up a PV guest in Xen, and I'm receiving the following error:
alpine-xen:~# xl create -f /etc/xen/a1.cfg -c
libxl: error: libxl_mem.c:202:libxl_set_memory_target: unable to retrieve domain configuration: No such file or directory
failed to free memory for the domain
I could not find any details about this error online. Could someone help me out with this?
Below are my outputs for xl list and xl info:

looks like you forgot to restrict the memory for dom0 on boot.
Depending on our hardware we need 256M up to 2048M for dom0.
you need to set it in these two files:
/boot/extlinux.conf
...
LABEL xen-vanilla
MENU LABEL Xen + Linux vanilla
COM32 mboot.c32
APPEND xen.gz dom0_mem=256M --- vmlinuz-vanilla root=...
...
and
/etc/update-extlinux.conf
...
xen_opts=dom0_mem=256M
...

I'm trying to use the torch/rnn toolkit to run RNNs on my nVidia graphics card. I've got an Ubuntu 16.04 VM with the nVidia driver, CUDA toolkit, Torch, and cuDNN working. I can run the mnistCUDNN example and nvidia-smi shows it using the graphics card. In Torch, I can require('cunn'); and it loads happily.
BUT when I dofile('./rnn/examples/recurrent-visual-attention.lua' ); inside Torch, I get
{

cuda : false

trainsize : -1
transfer : "ReLU"
uniform : 0.1

}
and since cuda:false, it runs using just the CPU.
Any ideas how to work out what I've missed? Thanks.
I'm an idiot. When I finally worked up the courage to read the source code, I discovered that it doesn't automatically try to use CUDA. There's a -cuda flag to ask it to.
In my defence, the examples are undocumented...
I was trying to print a document for one of my games but the page viewer couldn't see the printer so I checked the print spooler service

And tried to start it, then this happened

Ok so I checked the dependencies

OK seeing it stopped I tried to start it again
C:\WINDOWS\system32>net start http
System error 1009 has occurred.
The configuration registry database is corrupt.

So I run SFC to try and fix this BUT...
C:\WINDOWS\system32>sfc /scannow
Beginning system scan. This process will take some time.
Beginning verification phase of system scan.

Windows Resource Protection did not find any integrity violations.

A fat lot of help this is, it can't even fix something so inherently wrong...
So this is where I ask the community for help, I don't know what to do past this point. Help is very much appreciated.
In my case, I had a sub-key under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\SslBindingInfo that was missing information. i.e. all the keys such as 0.0.0.0:40015 have values like "AppId","DefaultFlags", etc.
I had one that had no values under this key. I deleted that "empty" key and HTTP was able to start up.
I've been trying to implement a artifact cleanup process based on https://www.jfrog.com/blog/advanced-cleanup-using-artifactory-query-language-aql/ ... but found that the AQL is really slow. i've seen queries still running after 24 hours with the server pinned at 100% cpu.
Using simple curl :
time curl -vv -u user:password -d "${query}" "http://server:8081/artifactory/api/search/aql"
I've measured :
items.find({"repo" : "ep-snapshots", "#milestone.keep": {"$ne" : "true"}, "#milestone.complete": {"$ne" : "true"}, "created": {"$before" : "3d"}}).limit(100)
33 minutes
items.find({"repo" : "ep-snapshots", "#milestone.keep": {"$ne" : "true"}, "#milestone.complete": {"$ne" : "true"}}).limit(100)
42 minutes
items.find({"repo" : "ep-snapshots", "#milestone.keep": {"$ne" : "true"}, "#milestone.complete": "false"}).limit(100)
574 minutes
Are there any techniques to investigate the performance of AQL ? Anything obviously broken with the above ?
Thanks,
Pete
I'm trying to use MediaInfo CLI (v0.7.77 on Mac OS X 10.9.5) to grab the first-frame timecode of QuickTime files using this Inform= syntax:
mediainfo --Inform="Other;%TimeCode_FirstFrame%" FILENAME.MOV
But it seems that MediaInfo ignores the existence of the "Other" section of the MediaInfo dump. It just outputs all of the file's metadata, as if I didn't enter an Inform= option at all.
However if I do something like this...
mediainfo --Inform="Video;%ColorSpace%" FILENAME.MOV
It simply returns "YUV", as expected, with no extraneous information.
So why won't my example using the Other; option work?
Here's an example of what I get when I do a language=raw dump of a typical source file:

This is a MediaInfo bug, will be corrected soon.
Jérôme, developer of MediaInfo.
For some reason my custom variables are not showing up in my Google Analytics reports (Visitors > Custom Variables > "There is no data for this view") even after 24 hours.
Anybody see what I'm missing?
I downloaded the Google Analytics Debugger (by Google) Chrome Extension and got the following report.

It works, apparently it takes a little longer for Custom Variables to show up in the reports. Thanks #yahelc
