A flaw in the RFC 5961 specification the Internet Engineering Task Force developed to protect TCP against blind in-window attacks could threaten Android smartphones, as well as every Linux computer on the planet. The flaw is described in a paper a team of researchers presented at the 25th Usenix Security Symposium, ongoing in Austin, Texas, through Friday.

Linux-operated botnet Distributed Denial of Service attacks surged in this year's second quarter, due to growing interest in targeting Chinese servers, according to a Kaspersky Lab report released this week. South Korea kept its top ranking for having the most command-and-control servers. Brazil, Italy and Israel ranked among the leaders behind South Korea for hosting C&C servers, according to Kaspersky Lab.

I joined a bunch of analysts in discussing Hewlett Packard Enterprise's next move at a secret conclave last week. The company had just announced the sale of its IT services, which basically undid much of Mark Hurd's work as CEO. It already had sold off PCs and printers, more than undoing Carly Fiorina's earlier efforts. Granted, HPE spun it like it was an acquisition.

Canonical on Thursday launched Ubuntu 16.04, aka "Xenial Xerus," an upgrade that will be supported for the next five years. The latest version for all desktop, server and cloud editions will be available for download starting Thursday. Ubuntu 16.04 includes four major technology advancements geared toward multiplatform uses. Xenial Xerus is the sixth Long Term Support release for Ubuntu.

Following Apple's latest announcements, I noticed a number of reports on how disappointed customers were that there was nothing they wanted to wait in line for hours to buy. I personally thought they should have been excited about that, because I hate to stand in lines. I've never really figured out an Apple fanatic's penchant for pain. Still, it is very clear that today's Apple is very different.

Microsoft on Tuesday announced plans to release a version of SQL Server 2016 for Linux. "Bringing SQL Server to Linux is another way we are making our products and new innovations more accessible to a broader set of users," said Microsoft's Scott Guthrie. SQL Server will be able to deliver a consistent data platform across Windows Server and Linux, in the cloud and on-premises.

A report released Tuesday on the DROWN vulnerability raises concerns about possible attacks that could expose encrypted communications. DROWN is a serious vulnerability that affects HTTPS and other services using SSL version 2, according to the team of security researchers who compiled the report. The protocols affected are some of the essential cryptographic protocols for Internet security.

Suse Linux has announced a partnership to extend support for 64-bit ARM server processors. The goal is to give Suse Linux Enterprise 12 users greater flexibility and cost efficiencies with respect to their infrastructures. This expansion makes available to seven partners a version of Suse Linux Enterprise 12 that lets them develop, test and deliver products to the market using 64-bit ARM chips.

Linbit on Tuesday announced the release of DRBD9, its new distributed replicated block device product. DRBD9 provides enterprise Linux users with synchronous server storage replication including support for native remote direct memory access and OpenStack integration. "It was six years of work and an 80 percent code rewrite to make it happen," said Linbit Business Development Manager Greg Eckert.

It was a little over a year ago that the Heartbleed bug shocked the Internet with its potential for mischief. Now another flaw in open source code has sent network administrators into damage control mode. The bug, called "Venom" for "Virtualized Environment Neglected Operations Manipulation," allows an intruder to jump out of a virtual machine and execute malicious code on its host.

Crowdstrike on Wednesday made public its discovery of yet another long-buried Linux vulnerability. "Venom," as it has been dubbed, was unearthed by the firm's senior security researcher, Jason Geffner. It is listed as vulnerability CVE-2015-3456. Venom exists in the virtual floppy drive code used by virtualization platforms based on QEMU, or quick emulator. It has been around since 2004.

Patches for GHOST, a critical vulnerability in glibc, the Linux GNU C Library, now are available through vendor communities for a variety of Linux server and desktop distributions. Qualys earlier this week reported its discovery of GHOST, a vulnerability that allows attackers to remotely take control of an entire system without having any prior knowledge of system credentials.

IBM launched its newest mainframe, the z13, last week in New York City. Built for the mobile economy, the z13 can process 2.5 billion transactions daily. It enables real-time encryption on all mobile transactions at scale, and it includes embedded analytics that provide real-time transactions faster and cheaper than the competition, the company said.

Banks and businesses toiled over the weekend to crush a bug in a widely used open source operating system. The flaw has been in Unix for some 25 years, but it was revealed just last week. If exploited, the vulnerability could be used to inject malicious code or take command of a system or device. Dubbed "Shellshock," it requires patching systems and devices running Apple's OS X, Linux and Unix.

Fires may be easy to start, but putting them out is a different matter. Case in point: the Systemd inferno. What started a few weeks ago as a relatively straightforward controversy over an oft-debated technology Visit the VMware Tech Center has now virtually blown up in Linux fans' faces. The latest flareup? None other than the suggestion that Linux be split in two.

Fedora is perhaps one of the hallmark Linux distributions. It is sponsored by Red Hat, the commercial developer of RHEL. Red Hat's investment in the Fedora community is collaborative. Fedora Linux releases often provide RHEL developers with a field test environment that incubates innovative open source software technologies. Red Hat Linux 1.0 was released in late 1994 as Red Hat Commercial Linux.

IBM's new Flex System compute node solutions -- the x280 X6, x480 X6 and x880 X6 -- don't qualify as anything new, some might say. After all, they utilize solutions announced months ago -- IBM's X6 in mid-January and Intel's Xeon E7v2 a month later -- which means they simply have been upgraded with the respective vendors' latest and greatest technologies.

A fire that erupted at the data center of Samsung SDS in Gwacheon, South Korea, reportedly took out services to Samsung smartphones, tablets and smart TVs for several hours. The company reportedly stopped all services offered through its website and smartphone apps, and said consumers could not use its online payment services or receive text message confirmations of payments made.

Like most small, inbred communities, Silicon Valley encourages and thrives on gossip, even when it's of little substance. In popular-speak, Valley gossip has a "low signal to noise ratio," but the rumor mill is vibrantly alive despite that shortcoming -- partly due to venture capitalists, whose efforts parallel the day-to-day business of technology.

During the heyday of the dot-com boom, then-HP CEO Carly Fiorina espoused "good enough" computing. Despite significant performance differences between x86 servers and Unix and other enterprise-class systems, the dramatically lower cost of x86-based products would cause organizations to rethink their computing priorities and adopt, buy and deploy x86 whenever and wherever possible, she maintained.

The open source business model has an inherent ability to bring software rivals together. This approach to developing and distributing software keeps expanding the usefulness and success of the Linux operating system as well. Linux has not yet come close to replacing Windows on the desktop, but open source is much more than Linux. Its "co-opetitive" nature is spreading through the enterprise.

Linux on the desktop may have missed its adoption time line, but Linux in the cloud is a win-win proposition for the post-PC movement. Microsoft's Azure may be the only real threat to Linux cloud dominance -- all other major cloud software platforms are based on Linux and open source software. Some enterprise Linux distros are showing up as cloud-based offerings.

Lenovo Group's $2.3 billion deal to purchase IBM's low-end, commodity x86 Server portfolios, related resources and operations is an all-around win for everyone involved. The sale of the IBM x86 servers has been rumored for well over a year, as Big Blue grappled with continuing pressure on its low-margin x86 servers. In its most recent quarter, IBM's revenue dropped 5.5 percent to $27.7 billion.

In case you missed last week's announcement that Lenovo would be acquiring IBM's System x x86 server business -- rumors had been making the rounds for months -- here are some of the details: Lenovo is acquiring IBM's x86 server hardware business for $2.3 billion, approximately $2 billion of which will be paid in cash and the balance in Lenovo stock.

Lenovo has struck a deal to acquire IBM's x86 server business. The deal, jointly announced Thursday, covers System x; BladeCenter and Flex System blade servers and switches; x86-based Flex integrated systems; NeXtScale and iDataPlex servers and related software; blade networking; and maintenance operations. Lenovo is paying around $2.3 billion for the business.

Mentioning virtualization technology to typical computer users in a work environment will get you a puzzled look. Despite the apparent obscurity of this IT trend, virtualization is making an increasingly large impact on SMBs. Some type of virtualization was reported in place by 77 percent of firms with 500 or fewer employees who responded to a recent survey.

The popularity of cloud storage is growing rapidly, and few would deny that open source technology is driving individual and business users to the clouds in droves. Yet enterprise adoption decisions are often hindered by competing technologies for public and private clouds. Often, it is less a question of open or closed source and more an issue of service and cost.

IBM's recent Enterprise 2013 conference in Orlando, Fla., was the Systems and Technology Group's inaugural event focusing on high-end business solutions. So it was no surprise that the CIOs, partners and IT practitioners -- data center admins and managers -- who work with IBM's System z mainframe and Power Systems platforms were thick on the ground.

Discuss the merits of the many competing desktop Linux distributions out there, and you could fill several hours with heated debate. Turn the conversation to enterprise server distros, however, and the room can become quiet very quickly. The fact is, those on the hunt for the best or easiest or cheapest enterprise Linux distro have far fewer choices.

Russia's Pirate Party wrote a letter to NASA offering to host the agency's website, which is currently out of commission because of the government shutdown. The Pirate Party -- a minority political movement in many European countries predicated on privacy and transparency -- informed NASA that it could use the party's dedicated servers until the U.S. government got off the ground.
