Juju and Charms for all Operating Systems | Openstack | Ubuntu Cloud

The latest development for Ubuntu Cloud services, tools and technologies is creatively called "Juju." It provides instant cloud solutions to build, integrate and scale services on any cloud in just seconds according to recent promotional texts. Probably the coolest feature of Juju is that it utilizes "Charms" to define applications as services. Currently there are 100's of Charms that have already been created by experts to help define infrastructure. Additionally users can easily create their own Charms to meet necessary infrastructure needs and requirements.

A few of the essential Charms to help you accomplish everything you need to include; WordPress, Hadoop, Cassandra, Ceph, MongoDB and MySQL.

With Apache Hadoop processing of large datasets can easily be spread out across a cluster of computers to accomplish that task much faster. MySQL is a fast and stable mulit-threaded SQL database server. By packaging these in Charm format they are highly scalable and can even be customized later.
Amazingly Juju is available for nearly any platform including; Ubuntu, Mac OS X, and Windows. To install on Mac OS X Homebrew is required. Juju has been packaged natively to install on Microsoft Windows 7 and 8.

Is there software like Logic Pro for Mac available for Ubuntu?



Most avid hobbyist musicians out there have likely heard of, or used, Logic Pro for Mac. This is one of many industry standard application for music creation; in fact it is even required by some college music programs. So you may be wondering, Is there anything like this for Ubuntu?

Well, yes, and a huge, resounding No! There are various Linux applications for music production but, nothing comes close to matching Logic Pro.

Digital Audio Workstation (DAW) Alternatives for Logic Pro, Cubase, or ProTools for Ubuntu:

OS X 10.8.4 | i5 3570k | Gigabyte Z77-DS3H | 8 GB RAM | NVIDIA GT620 HDMI DVI VGA Working

Are you looking for a cheap, effective and most importantly, OS X compatible Hackintosh system build? Choosing a motherboard can be one of the most difficult tasks, as this is the most critical component that must be compatible with OS X. Arguably the best motherboards for building a Hackintosh are made by Gigabyte; having almost complete driver compatibility with OS X.

NZXT Source 210 ELITE Midtower Case


For this build the Gigabyte Intel Z77 LGA 1155 Dual UEFI BIOS ATX Motherboard GA-Z77-DS3H was used. Installation of OS X 10.8.3 (later 10.8.4) is nearly as simple as installing a Windows operating system. Changing SATA mode in bios to AHCI is the only bios preference that needs to be changed before beginning the installation.

i5 motherboard gigabyteWhen combined with an Intel Core i5-3570K Quad-Core Processor this machine boasts phenomenal geek bench scores, handling many intense operations with ease. To further improve on this build without needing to modify the installation method an Intel Core i7-3770K Quad-Core Processor could be substituted for the 3570K. Both of these processor options permit the use of Intel HD4000 integrated graphics, however this is not recommended if you would like use of a VGA port, still common on many monitors.

Gigabyte GeForce GT 620 1GB DDR3 PCI Express 2.0 DVI-I/D-SUB/HDMI Low Profile Graphics Card GV-N620D3-1GL
All of the Nvidia GT 600 series graphics cards should be fully compatible out of the box; OS X already has these drivers! For a cost effective and balanced graphics card, the Gigabyte GeForce GT 620 1GB DDR3 PCI Express 2.0 Graphics Cardis an excellent choice ($55.00). This card would not be recommended for transcoding/editing video, but it is a great choice for the everyday user or music production center. 

Corsair Vengeance 16GB (2x8GB) DDR3 1600 MHz (PC3 12800) Desktop Memory (CMZ16GX3M2A1600C10)
To harness the power of the i5 3570K or i7 3770K at least a Corsair Vengeance 8 GB ( 2 x 4 GB ) DDR3 1600 MHz Memory Kit or for Logic Pro X users, a Corsair Vengeance  16GB (2x8GB)  DDR3 1600 MHz Desktop Memory Kit should be used to provide ample room for loading large virtual instruments or intense multi tasking.

Corsair CX Series 750 Watt ATX/EPS Modular 80 PLUS Bronze ATX12V/EPS12V 744 Power Supply CX750MWe're almost done with this build except for a power supply. When choosing a power supply you want to be sure you think ahead for future expansions. Sure, 4 SATA power ports and one 6-Pin PCI may be enough now, but not when you want to add a few more hard drives or optical drives or maybe even two graphics cards bridged via SLI. It may seem like a waste of money to purchase a high end power supply but it will save you from many headaches in the future. I have found that some of the lower end power supplies do not even have a long enough CPU power cable to reach the motherboard if the case requires bottom mounting of the power supply (like this NZXT Case). Also an efficient power supply can drastically reduce system temperatures, mainly by reducing case temperatures, maintaining a cooler environment can be critical to prolonging system life and pushing a higher over-clock. 

This Corsair CX Series 750 Watt ATX/EPS Modular 80 PLUS Bronze Power Supply is an excellent choice. It provides 2 PCI-E, 6 SATA, and 4 4-Pin peripheral connectors, all while being rated 80+ Bronze efficiency. Also the modular cabling system allows you to connect only the cables you need so as not to interfere with airflow and reducing clutter inside the case.

Multibeast Settings:




After completing the MultiBeast installation, while booting, the Apple boot screen would not go away, and the progress indicator would spin indefinitely. At this time I was using a VGA display which is not supported by the Apple HD4000 kernel extension. After switching to an HDMI display I was no longer haunted by the eternal Apple boot screen, but rather an astoundingly quick boot followed by a complete loss of signal to the HDMI display. After trying the go to troubleshooting technique of unplugging and re-inserting the HDMI cable in the motherboard to no avail, I realized that the computer had booted completely but left me with no video signal.

Using boot flag PCIRootUID=1, the system would boot completely, but the HD4000 graphics were not functioning as they should, and appeared to be using only basic generic drivers/kexts rendering the graphics flickering and laggy. I thought, at least now I will be able to test the audio, NOPE! No audio output or input options were available in System Preferences>>Audio.

After installing, uninstalling, and reinstalling various drivers for Intel HDA with only partial successes, cracking and popping, but now with available inputs and outputs displayed in Audio preferences, I reinstalled OS X Combo Update 10.8.4 to reset all audio kexts I had messed with. This time booting with PCIRootUID=0 and using a GeForce 8400 GS graphics card I was able to boot flawlessly  into OS X Mountain Lion 10.8.4 with adequate graphics performance and crystal clear audio!

It would seem to me that the Intel HD 4000 graphics may not be fully or properly supported on the Gigabyte Z77-DS3H motherboard or within OS X. For those considering a similar build I recommend ditching the integrated graphics and spending a few bucks on a well supported Nvidia graphics card. This will surely save you much head banging while installing your build.
