  • What’s new in SSHGuard 2.0

    SSHGuard is an intrusion prevention utility that parses logs and automatically blocks misbehaving IP addresses with the system firewall. It’s less configurable than the better-known Fail2Ban but has a smaller resource footprint and ships with full IPv6 support. The newly released SSHGuard version 2.0 have been made easier to configure for new users. It also gained support for FirewallD, ipset, and ipfilter firewall backends on Linux; as well as Capsicum sandboxing support on *BSD.

    While we’re still waiting for the next release of Fail2Ban with IPv6 support, I took a look around at some of the alternatives and found an interesting option in SSHGuard. I had to address some Linux compatibility issues when getting started with SSHGuard as the development team was mostly focused on FreeBSD. I submitted patches for those issues and got more involved in the development and release of SSHGuard 2.0 in the process.

    Today we are going to discuss the same topic once again but the method is completely different. I mean, i will show you, how to hide sensitive data inside image and audio files using steghide utility.

  • 3 Emacs extensions for getting organized

    In the colophon to his book, Just a Geek, actor and writer Wil Wheaton wrote that he wanted to use Emacs to write the book but "couldn't find the text editor." Wheaton was joking, of course, but he highlighted an important point about Emacs: it's gone way beyond its roots as a tool for editing text.

    Thanks to its many modes (extensions that change the way the editor behaves), you can use Emacs for just about anything: browsing the web, reading and sending email, publishing blog posts and books, managing databases, learning with flashcards, and much more.

  • Openlab: what it is and why it matters
    Six months on from its announcement at Openstack Summit Sydney in late 2017, community testing project OpenLab is in full swing. OpenLab was initially formed by Intel, Huawei and the OpenStack foundation as a community-led project for improving SDK support and also introducing other platforms like Kubernetes and Cloud Foundry to the Openstack environment. Ultimately the idea is to improve usability in hybrid and multi-cloud environments. Melvin Hillsman sits on the governance board along with Dr Yih Leong Sun of Intel and Chris Hoge from the Foundation. Hillsman moved from Rackspace to Huawei to work specifically on the project. "The reason we think Openlab is important is, basically, Openstack for some time has been very specific about testing and integration for Openstack services, focusing only on the projects started at Openstack," Hillsman tellsComputerworld UK at the Openstack Vancouver Summit. "It's been working very well, it's a robust system. But for me as a person in the user community - my getting involved in Openstack was more on the operator-user side.
  • Open source innovation tips for the customer-driven economy
    New technologies, ranging from big data and blockchain to 3D printing, are giving rise to new opportunities and challenges for companies today. To stay competitive, organizations need to become more intelligent, customer-centric, and increasingly agile to cope with changing business demands. The worry for many companies which are trying to innovate is that while the speed and scope of applications are expanding rapidly, the variety and complexity of technology is increasing simultaneously, putting pressure on their IT infrastructure. Speaking at the SUSE Expert Days 2018 held in Singapore recently, Dr Gerald Pfeifer, VP of Products and Technology Program, SUSE, told attendees that these prevailing trends have come together to make Open Source the primary engine for business innovation.
  • Qualcomm is able to release the Snapdragon 845 source code in 6 weeks
    Qualcomm‘s latest high-end system-on-chip, the Qualcomm Snapdragon 845, was announced at the Snapdragon Tech Summit back in December. The chipset offers 4 Kryo 385 (A75 “performance”) and 4 Kryo 385 (A55 “efficiency”) CPU cores, the latest Adreno 630 GPU, the Spectra 280 ISP, the Hexagon 685 DSP, the Snapdragon X20 LTE modem, and a new Secure Processing Unit (SPU). The Snapdragon 845 SoC is a powerhouse in benchmarks and it is already available in devices like the Samsung Galaxy S9/S9+, Xiaomi Mi Mix 2S, and the OnePlus 6. Developers on our forums have been itching to get their hands on a device with Qualcomm’s latest and greatest, but there’s just one thing that has made some developers worry about the future of development on the platform: The lack of publicly available source code for the kernel, HALs, framework branches, and more on the CodeAurora Forums.
  • Kata Containers 1.0 Released, Formerly Intel Clear Containers
    Back in December was the announcement of Intel's Clear Containers being spun into a new project called Kata Containers in collaboration with other organizations. Kata Containers has now reached their version 1.0 milestone. Kata Containers 1.0 is now available for this container technology designed for offering a secure and scalable container experience built atop Intel VT technology.
  • What's new in OpenStack?
    As OpenStack Foundation Chief Operating Officer Mark Collier referenced in his opening keynote, the uses which OpenStack is seeing today expand far beyond what most who were involved in the early days of the project could have ever imagined. While OpenStack started out primarily in the traditional data center and found many large-scale users, particularly in the telecommunications industry, who were using it to manage huge installations of traditional x86 server hardware, the flexibility of OpenStack has today allowed it to thrive in many other environments and use cases. Today, we see OpenStack powering everything from academic and research projects to media and gaming services, from online retail and e-commerce to manufacturing and industrial applications, and from finance to healthcare. OpenStack is found in all of these different places not just because it is cheaper than using the public cloud, not just because it makes compliance with various regulations easier, but because its open source code makes it flexible to all sort of different situations.
  • Should Red Hat Buy or Build a Database?
    For a decade, at least, observers of the company have speculated about whether Red Hat would or should enter the database market. The primary argument, one made in this space eight years ago, has historically been that Red Hat is de facto leaving potential dollars on the table by limiting itself to operating platform and immediately adjacent markets. In a more recent piece, analyst Krishnan Subramanian adds that Red Hat is at risk because databases represent a control point, one that the company is effectively ceding to competitors such as AWS or Microsoft.
  • Tidelift Raises $15M Series A From General Catalyst, Foundry, & Others
    This morning Tidelift, a startup focused on helping developers work with open source technology, announced that it has closed a $15 million Series A round of funding co-led by General Catalyst, Foundry, and Matthew Szulik, the former CEO of Red Hat, a public open source-centered technology company. The subscription-powered startup has an interesting business model which we’ll dive into shortly, but it’s worth noting that the open source space as a whole is quite active. It’s something that Crunchbase News covered last year, describing how startups working with open source software have enjoyed a dramatic rise in investor interest. That puts Tidelift in the midst of a trend.
  • Tidelift lands $15M to deliver professional open-source support
    Tidelift Inc. is raising $15 million as it looks to boost its unique open-source software model that sees companies pay for professional support of their favorite projects, allowing those that maintain them to get compensated too. The Series A round was led by the investment firms General Catalyst and Foundry Group, as well as former Red Hat Inc. Chairman and Chief Executive Matthew Szulik. The company was able to attract the investment after coming up with a novel idea for maintaining the most popular open-source software projects in a way that benefits both the users and those who help to create them. It works like this: Companies pay a subscription fee that entitles them to professional-grade support, similar to the kind of commercial subscriptions offered by firms such as Red Hat, Cloudera Inc. and Docker Inc. A part of these fees are then used to pay the developers who maintain the software. The net result, at least in theory, is that everyone is happy, as companies enjoy the benefits of professional support at lower rates than they might expect from an established firm, and the developers of the software are finally rewarded for their efforts.

  • Ubuntu's Shuttleworth Creates Controversy with OpenStack Summit Vancouver Keynote
    The OpenStack Foundation is facing a bit of drama and controversy as it deals with issues related to a keynote delivered by Ubuntu Linux founder, Mark Shuttleworth at the OpenStack Summit here on May 21. Typically the OpenStack Foundation posts videos of all its session online within 24 hours, but with the Shuttleworth keynote, the video was apparently posted and then promptly removed. During his keynote, Shuttleworth took direct aim at his OpenStack competitor Red Hat, which apparently made some people in the OpenStack Summit community uncomfortable.
