It is actually an update for Neutron on Kilo of original blog entry http://techbackground.blogspot.ie/2013/06/metadata-via-quant... considering Quantum implementation on Grizzly. From my standpoint understanding of core architecture of Neutron openstack flow in regards of nova-api metadata service access (and getting proper response from nova-api service) by VMs launching via nova causes a lot of problems due to leak of understanding of core concepts.

It looks like some very poor accounting is to blame

The Ubuntu Community Council has made a rather troublesome discovery regarding the accounting of $143,000 in donations. From the looks of it, no one knows how this money was spent.

Many of the changes in Fedora 22 come in the Cloud and Server versions, though one change stands out across the board. DNF, an updated package manager that has been around in development since Fedora 18, finally makes its debut here, replacing Yum. DNF provides faster installs and updates while keeping the Yum command-line interface compatibility — but instead of “yum” you’ll be typing “dnf” on the command line. Pretty simple, no?

In my previous article, 8 Linux file managers to try, I compared a number of file managers, but there was not enough space to go into detail about any of the several file managers that I mentioned briefly. This article will delve a bit further into Midnight Commander, and I plan to write more to cover some of the other file managers in more detail. read more

No matter what desktop environment you choose to work with, or if you prefer playful docks to classic menus, your system's main repository of applications will always lie on your main menu, found on a corner of your screen or on the center of it in the case that you are using GNOME Shell. One easy way to modify your main menu entries is to use the Alacarte menu editor, another way is to use the FileManager.

LG and Sony (of Rockstar Consortium) follow Samsung and Dell in Microsoft’s campaign to turn Android into ‘Microsoft Android’ using patents-induced pressure/leverage

By now, you’ve probably met the donate page on Ubuntu, the one you see when you go to download an Ubuntu ISO. This donation page has led to a schism between the Ubuntu Community Council and Jonathan Riddell, the ‘leader’ of the Kubuntu project. All stemming from a perceived lack of transparency regarding donations made to Canonical.

Fedora 22 was released yesterday... so I updated the Fedora 22 OpenVZ OS Template I created to be current and submitted it to contrib. For the fun of it I made a screencast that shows making a Fedora 22 container and then installing the MATE desktop environment along with a handful of common desktop applications and how to access everything via x2go.

"Developed many years before by some high-strung, compulsive assistant, the Bulletin was simply a Word document that lived in a shared folder both Emily and I could access. Only one of us could open it at a time and add a new message, thought, or question to the itemized list. Then we'd print out the...

The Supreme Court issued a ruling today in Commil USA v. Cisco Systems, one of two patent cases it heard this term. On one key issue, the opinion favors Commil, a "patent troll" that won a $64 million jury verdict against Cisco. But other findings mean that the non-practicing entity won't be getting a payday any time soon—and a final section of the opinion is wholly dedicated to reminding judges to sanction misbehaving patent plaintiffs, something that didn't even come up in this case.

Xfce's Power Manager was getting behind the times, but it has been updated and ported to GTK+ 3.14. As you can imagine, this is an important update, and it packs other changes as well.

The UK government has decided, as foreshadowedby The Reg, that it can do without extended support for Windows XP.

A worm that targets cable and DSL modems, home routers, and other embedded computers is turning those devices into a proxy network for launching armies of fraudulent Instagram, Twitter, and Vine accounts as well as fake accounts on other social networks. The new worm can also hijack routers' DNS service to route requests to a malicious server, steal unencrypted social media cookies such as those used by Instagram, and then use those cookies to add "follows" to fraudulent accounts. This allows the worm to spread itself to embedded systems on the local network that use Linux-based operating systems.

Solus is not new, but its concept kind of is. The story of Solus starts a few years ago, back in 2012, when Intel employee Ikey Doherty announced the first ever version of his distro, called SolusOS, based on Debian GNU/Linux and built around the GNOME 2 desktop environment.
