nVidia Fixes Linux Bug
Nvidia has fixed an ancient problem in Ubuntu systems which turned the screen into 40 shades of black.
The problem has been around for years and is common for anyone using Nvidia gear on Ubuntu systems.
When opening the window of a new application, the screen would go black or become transparent. As it turns out, this is actually an old problem and there are bug reports dating back from Ubuntu 12.10 times.
However to be fair it was not Nvidia’s fault. The problem was caused by Compiz, which had some leftover code from a port. Nvidia found it and proposed a fix.
“Our interpretation of the specification is that creating two GLX pixmaps pointing at the same drawable is not allowed, because it can lead to poorly defined behavior if the properties of both GLX drawables don’t match. Our driver prevents this, but Compiz appears to try to do this,” wrote NVIDIA’s Arthur Huillet.
Soon after that, a patch has been issued for Compiz and it’s been approved. The patch would be pushed in Ubuntu 15.04 and is likely to be backported to Ubuntu 14.04 LTS.
RHEL Finally Available On IBM’s Power8
Comments Off on RHEL Finally Available On IBM’s Power8
IBM has made the Power8 version of the latest Red Hat Enterprise Linux (RHEL) beta available through its Power Development Platform (PDP) as the firm continues to build support for its Power systems.
IBM and Red Hat announced in December that RHEL 7.1 was adding support for the Power8 processor in little endian instruction format, as the beta release was made available for testers to download.
This version is available for developers and testers to download from today through the IBM PDP and at IBM Innovation Centres and Client Centres worldwide, IBM announced on its Smarter Computing blog.
“IBM and Red Hat’s collaboration to produce open source innovation demonstrates our commitment to developing solutions that efficiently solve IT challenges while empowering our clients to make their data centres as simple as possible so they can focus on core business functions and future opportunities,” said Doug Balog, general manager for Power Systems at IBM’s Systems & Technology Group.
The little endian support is significant because IBM’s Power architecture processors are capable of supporting little endian and big endian instruction formats. These simply reflect the order in which bytes are stored in memory.
The Power platform has long had Linux distributions and applications that operate in big endian mode, but the much larger Linux ecosystem for x86 systems uses little endian mode, and supporting this in Red Hat makes it much easier to port applications from x86 to Power.
Suse Linux Enterprise Server 12 launched last year with little endian support for the Power8 processor, as did Canonical’s Ubuntu 14.04 LTS.
However, Red Hat and Suse are understood to be continuing to support their existing big endian releases on Power for their full product lifecycles.
IBM sold off its x86 server business to Lenovo last year, and has focused instead on the higher value Power Systems and z Systems mainframes.
In particular, the firm has touted the Power Systems as more suitable for mission critical workloads in scale-out environments like the cloud than x86 servers, and has been forging partnerships with firms such as Red Hat through its OpenPower Foundation.
Is China Spying?
Security experts claim that a Chinese manufacturer has been installing malware in its hand-held scanners that steals supply chain data.
TrapX says infected scanners made by an unnamed Chinese manufacturer located in Shandong province have been sold to eight unnamed firms including a large robotics company. The manufacturer denied knowledge that its scanners and website-hosted software were infected.
Sixteen of the 48 scanners deployed at one firm were infected, TrapX found. They all successfully sought out and compromised host names containing the word finance and siphoning off the logistical and financial data. The report Anatomy of the Attack: Zombie Zero said:
“Exfiltration of all financial data and ERP data was achieved, providing the attacker complete situational awareness and visibility into the logistic/shipping company’s worldwide operations,”.
TrapX suspected the attacks dubbed Zombie Zero were backed by the Chinese government and were a bid to gain intelligence on either logistics firms or their customers.
Is RedHat Being Open?
Red Hat has responded to claims that its implementation of Openstack isn’t as open as it should be.
A report at the Wall Street Journal this week suggested that Red Hat was blocking customers from using alternatives to the bespoke version of Openstack that it offers.
Red Hat provides Openstack with extended support by the company, however in spirit of open source, users should be entitled to use another vendor’s Openstack software, the generic Openstack, or create their own fork.
In reality though, the Wall Street Journal report suggests that Red Hat customers have been advised that Red Hat will not support mixed vendor software, that it has claimed it would cost the company too much to support multiple Openstack distributions and that Red Hat Linux and Red Hat Openstack are too closely intertwined to be separated.
Openstack’s open character is part of what makes it what it is, it’s embedded in the name, and Red Hat has been quick to distance itself from the report, though it does hedge a bit.
In a blog post, Paul Cormier, president of the company’s Products and Technologies division said, “Red Hat believes the entire cloud should be open with no lock-in to proprietary code. Period. No exceptions. Lock-in is the antithesis of open source, and it goes against everything Red Hat stands for.”
However, he went on to warn, “[Red Hat Enterprise Linux OpenStack Platform] requires tight feature and fix alignment between the kernel, the hypervisor, and Openstack services. We have run into this in actual customer support situations many times.”
In other words, its advice to customers is seemingly ‘of course you can do it, but you’d have to be a bit daft’.
He went on to explain, “Enterprise-class open source requires quality assurance. It requires standards. It requires security. Openstack is no different. To cavalierly ‘compile and ship’ untested Openstack offerings would be reckless. It would not deliver open source products that are ready for mission critical operations and we would never put our customers in that position or at risk.”
Which suggests that Red Hat will let you use your own version, unless it’s not happy with it, in which case it won’t.
In a swipe at HP, Cormier concluded by attacking its rival, saying, “We would celebrate and welcome competitors like HP showing commitment to true open source by open sourcing their entire software portfolio.”
HP, which recently launched its HP Helion brand for Openstack, would probably argue that it has already done this, so the war of words might just be beginning.
Can Plastic Replace Silicon?
Can plastic materials morph into computers? A research breakthrough recently published brings such a possibility closer to reality.
Researchers are looking at the possibility of making low-power, flexible and inexpensive computers out of plastic materials. Plastic is not normally a good conductive material. However, researchers said this week that they have solved a problem related to reading data.
The research, which involved converting electricity from magnetic film to optics so data could be read through plastic material, was conducted by researchers at the University of Iowa and New York University. A paper on the research was published in this week’s Nature Communications journal.
More research is needed before plastic computers become practical, acknowledged Michael Flatte, professor of physics and astronomy at the University of Iowa. Problems related to writing and processing data need to be solved before plastic computers can be commercially viable.
Plastic computers, however, could conceivably be used in smartphones, sensors, wearable products, small electronics or solar cells, Flatte said.
The computers would have basic processing, data gathering and transmission capabilities but won’t replace silicon used in the fastest computers today. However, the plastic material could be cheaper to produce as it wouldn’t require silicon fab plants, and possibly could supplement faster silicon components in mobile devices or sensors.
“The initial types of inexpensive computers envisioned are things like RFID, but with much more computing power and information storage, or distributed sensors,” Flatte said. One such implementation might be a large agricultural field with independent temperature sensors made from these devices, distributed at hundreds of places around the field, he said.
The research breakthrough this week is an important step in giving plastic computers the sensor-like ability to store data, locally process the information and report data back to a central computer.
Mobile phones, which demand more computing power than sensors, will require more advances because communication requires microwave emissions usually produced by higher-speed transistors than have been made with plastic.
It’s difficult for plastic to compete in the electronics area because silicon is such an effective technology, Flatte acknowledged. But there are applications where the flexibility of plastic could be advantageous, he said, raising the possibility of plastic computers being information processors in refrigerators or other common home electronics.
“This won’t be faster or smaller, but it will be cheaper and lower power, we hope,” Flatte said.
Dell RedHat Join Forces
The Dell Red Hat Cloud solution, a co-engineered, enterprise grade private cloud, was unveiled at the Red Hat Summit on Thursday.
The Openstack-based service also includes an extension of the Red Hat partnership into the Dell Openshift Platform as a Service (PaaS) and Linux Container products.
Dell and Redhat said their cloud partnership is intended to “address enterprise customer demand for more flexible, elastic and dynamic IT services to support and host non-business critical applications”.
The integration of Openshift with Redhat Linux is a move towards container enhancements from Redhat’s Docker platform, which the companies said will enable a write-once culture, making programs portable across public, private and hybrid cloud environments.
Paul Cormier, president of Products and Technologies at Red Hat said, “Cloud innovation is happening first in open source, and what we’re seeing from global customers is growing demand for open hybrid cloud solutions that meet a wide variety of requirements.”
Sam Greenblatt, VP of Enterprise Solutions Group Technology Strategy at Dell, added, “Dell is a long-time supporter of Openstack and this important extension of our commitment to the community now will include work for Openshift and Docker. We are building on our long history with open source and will apply that expertise to our new cloud solutions and co-engineering work with Red Hat.”
Dell Red Hat Cloud Solutions are available from today, with support for platform architects available from Dell Cloud Services.
Earlier this week, Red Hat announced Atomic Host, a new fork of Red Hat Enterprise Linux (RHEL) specifically tailored for containers. Last year, the company broke bad with its Fedora Linux distribution, codenamed Heisenbug.

Facebook Goes Ten

Comments Off on Facebook Goes Ten
Facebook plans on celebrating its 10th birthday today, an occasion likely to spur an outpouring of reflection on its past and speculation about its future.
Mark Zuckerberg launched “Thefacebook” from his dorm room at Harvard University on Feb. 4, 2004. The site was conceived as a way to connect students, and let them build an online identity for themselves.
It has since expanded to cover a large swath of the planet, with more than 1.2 billion people — one-seventh of the world’s population — using its site on a monthly basis, according to the company’s own recent figures.
Zuckerberg reflected on the 10-year milestone at an industry conference in Silicon Valley this week. Not surprisingly, at the start he never envisioned Facebook becoming so large or influential. After launching the initial version, “it was awesome to have this utility and community at our school,” he said at the Open Compute Project Summit.
He figured at the time that someone, someday would build such a site for the world. “It didn’t even occur to me that it could be us,” he said.
Since then, Facebook’s site and its business, now a public company, have changed dramatically. There are now more than a trillion status updates, text posts and other pieces of content stored within its walls — the company is trying to index them as part of its Graph Search search engine.
The company was slow to react to the important mobile market, and when it went public in 2012 investors were skeptical it would be able to monetize its service on smaller screens. But this week it reported that more than half its ad revenue now comes from mobile devices.
All the while, Facebook is making its ad business smarter, using targeting tools to show ads it deems most relevant.
The company is also experimenting with new ways to present content. Next week it will release Paper, an iPhone app that provides a new way to share photos and published articles.
It’s part of a larger effort Facebook hinted at this week to release a variety of standalone apps for different tasks.
The company is also trying to bring the Internet to more people in the world, an effort that’s part philanthropy and part business sense as Facebook aims to reach its next billion users. Asked this week why he launched the project, called Internet.org, Zuckerberg suggested he feels a weight of responsibility.
“There aren’t that many companies in the world that have the resources and the reach that Facebook has at this point,” he said.
Red Hat Releases Fedora 19
Red Hat has released Fedora 19, codenamed Schrödinger’s Cat, which has support for 3D printing and is the first to use MariaDB as its default SQL database instead of Oracle’s MySQL.
Red Hat’s Fedora Linux distribution is the testing ground for the firm’s hugely successful Enterprise Linux (RHEL) distribution, and for that reason it heralds what will appear in future releases of RHEL. The firm’s Fedora 19 release brings support for 3D printing through OpenSCAD, Skeinforge, SFACT, Printrun and Repetierhost, and it is the first release to make MariaDB the default SQL database server implementation in place of Oracle’s MySQL.
The Fedora Project was criticised for delaying its Fedora 18 release, however Fedora 19 appeared on time. Fedora’s latest release includes Gnome 3.8 and the capability to enable Gnome Classic, a Gnome 2 type user interface, along with KDE Plasma 4.10 and Mate 1.6, with other window managers such as Xfce and Lxde available in different spins.
As Red Hat sponsors the Fedora Project it is not surprising to see Fedora include Openshift, the firm’s platform as a service infrastructure. Fedora 19 also includes node.js and Ruby 2.0, but arguably its biggest move is away from Oracle’s MySQL to the community maintained MariaDB fork, which suggests that eventually RHEL will make MariaDB its default SQL database implementation.
The Fedora Project has said that work on Fedora 20 has been in active development for several months and it plans to release that in November.
Fedora 19 is available for download from regional mirrors and users can also use Fed Up to upgrade from previous versions of the distribution.
Anonymous Goes After North Korea
Anonymous has restarted its attack against North Korea and once again is using a North Korean Twitter account to announce website scalps.
The Twitter account @uriminzok was the scene of announcements about the hacked websites during the last stage of Op North Korea, and reports have tipped up there again.
The first wave of attacks saw a stream of websites defaced or altered with messages or images that were very much not in favour of the latest North Korean hereditary leader, Kim Jong-un.
They were supported by a Pastebin message signed by Anonymous that called for some calming of relations between North Korea and the US, and warned of cyber attacks in retaliation.
“Citizens of North Korea, South Korea, USA, and the world. Don’t allow your governments to separate you. We are all one. We are the people. Our enemies are the dictators and regimes, our goals are freedom and peace and democracy,” read the statement. “United as one, divided by zero, we can never be defeated!”
Before the attacks restarted, the last Twitter message promised that more was to come. It said, “OpNorthKorea is still to come. Another round of attack on N.Korea will begin soon.” Anonymous began delivering on that threat in the early hours this morning.
More of North Korean websites are in our hand. They will be brought down.

We’ve counted nine websites downed, defacements and hacks, and judging by the stream of confirmations they happened over a two hour period. No new statement has been released other than the above.

Downed websites include the glorious uriminzokkiri.com, a North Korean news destination. However, when we tried it we had intermittent access.
Last time around the Anonymous hackers had taken control of North Korea’s Flickr account. This week we found the message, “This member is no longer active on Flickr.”
Red Hat Outs Fedora 17
Red Hat has released its Fedora 17 ‘Beefy Miracle’ distribution just over a month after Canonical released its Ubuntu 12.04 distribution.
The Red Hat sponsored Fedora project serves as the proving ground for new features that eventually end up in the firm’s Red Hat Enterprise Linux (RHEL) operating system. Now Red Hat has announced that it has released Fedora 17 including updates to Gnome, Eclipse, GIMP and Openstack along with numerous patches.
Canonical’s Ubuntu Linux distribution might have shunned Gnome 3 in favour of its Unity desktop interface but Red Hat continues to stick with Gnome in Fedora, shipping Gnome 3.4 as its default window manager. Fedora 17 also includes GIMP 2.8 and Openstack Essex, while developers who like to live on the edge can run Eclipse Juno, the full release of which is expected later this year.
Fedora project leader Robyn Bergeron said, “I am extremely proud of the Fedora 17 release. The addition of projects such as Ovirt [virtual machine management] and JBoss Application Server 7, enhancements in Openstack, and continued support for fresh releases of desktop environments demonstrate the Fedora Project’s commitment to deliver rich features and capabilities. This, combined with our leading-edge innovations at the operating-system level, truly makes Fedora 17 a comprehensive and robust operating system for all types of users.”
