linux streaming music server

Criteria:
Be able to stream music, but be controlled via a webpage or android application.

mpd – great linux server that has a massive following
- great tutorial and examples

Premade 3d Printers

So far this one looks to be the most economical.

UP! costs around $1500

MakerBot costs a little more at $1749.00, but has been around and is a tried and true machine.

PrintBot is still the cheapest at $499

Centos 6 Kickstart

Compiling handbrake on centos

Reference pulled from Ben’s Journal.

The fix turned out to be as follows. I edited the file:

 ./contrib/libvorbis/module.defs

and changed:

 LIBVORBIS.CONFIGURE.bootstrap = rm -fr aclocal.m4 autom4te.cache configure; autoreconf -I m4 -fiv;

to:

LIBVORBIS.CONFIGURE.bootstrap = rm -fr aclocal.m4 autom4te.cache configure; sh autogen.sh;

(and yes, that trailing ‘;’ is necessary)

This is the specs for my current gaming rig, and I’ve been very happy with it for about 2 years now. There have been some updates like the graphics card, but for the most part it’s been static. I tend to do more than one things at a time, more like 6-10 things at a time. Most of them include playing BF3 on one screen while running a windows vm on the other screen that is installing 3 servers remotely. No.. my demands aren’t high at all for my desktop, but I honestly can see my demands increasing. I also do video editing/encoding while I’m doing these things as well, so the more cores I can put on a system the better.

Creating a bootable Windows Installation USB

You can use the application attached to this post to allow drag/drop creation of a bootable usb stick. Download here. I like the solution, but I want to be able to boot form iso images placed on the stick, not just create bootable directories from the iso.

Grub, the morning after
