OpenBSD Is Getting Its Own Native Hypervisor

Filed under
BSD

The OpenBSD Foundation has been funding work on a project to provide OpenBSD with its own, native hypervisor.

The hypervisor's VMM is so far able to launch a kernel and ask for a root file-system, but beyond that, it's been laying most of the hypervisor foundation up to this point.

The Death of Ubuntu's Software Center

Filed under
Ubuntu

Over the past few weeks, the fate of Ubuntu's Software Center has received a lot of press. There have been ample ravings about how the Software Center is about to vanish from the face of the Earth. In reality, it's not going anywhere yet. What is changing, however, will be the ability to submit new applications or updates to existing applications. In this article, I'll explain what this means and where things will likely go from here.

Exclusive Interview: Michael Miller of SUSE Talks About Transition and Contributing to Open Source

Filed under
Interviews
SUSE

SUSE is one of the Linux trinity -- which comprises Red Hat, SUSE, and Canonical. SUSE is also one of the leading contributors to many open source projects, including the kernel itself. However, the company went through challenging times as it was acquired by one company after another. It seems that things have stabilized with the Micro Focus acquisition, so I sat down with Michael Miller, SUSE’s Vice President of Global Alliances & Marketing at LinuxCon and talked about topics ranging from acquisition to future plans.

Linux firewalls: What you need to know about iptables and firewalld

A firewall is a set of rules. When a data packet moves into or out of a protected network space, its contents (in particular, information about its origin, target, and the protocol it plans to use) are tested against the firewall rules to see if it should be allowed through. Here’s a simple example... Read more

Mozilla: Firefox GCC/LLVM Clang Dilemma, September 2018 CA Communication and CfP

  • Fedora Firefox – GCC/CLANG dilemma
    After reading Mike’s blog post about official Mozilla Firefox switch to LLVM Clang, I was wondering if we should also use that setup for official Fedora Firefox binaries. The numbers look strong but as Honza Hubicka mentioned, Mozilla uses pretty ancient GCC6 to create binaries and it’s not very fair to compare it with up-to date LLVM Clang 6. Also if I’m reading the mozilla bug correctly the PGO/LTO is not yet enabled for Linux, only plain optimized builds are used for now…which means the transition at Mozilla is not so far than I expected.
  • September 2018 CA Communication
    Mozilla has sent a CA Communication to inform Certification Authorities (CAs) who have root certificates included in Mozilla’s program about current events relevant to their membership in our program and to remind them of upcoming deadlines. This CA Communication has been emailed to the Primary Point of Contact (POC) and an email alias for each CA in Mozilla’s program, and they have been asked to respond to the following 7 action items:
  • Emily Dunham: CFP tricks 1
    Some strategies I’ve recommended in the past for dealing with this include looking at the conference’s marketing materials to imagine who they would interest, and examining the abstracts of past years’ talks.

Security: Quantum Computing and Cryptography, Time to Rebuild Alpine Linux Docker Container

  • Quantum Computing and Cryptography
    Quantum computing is a new way of computing -- one that could allow humankind to perform computations that are simply impossible using today's computing technologies. It allows for very fast searching, something that would break some of the encryption algorithms we use today. And it allows us to easily factor large numbers, something that would break the RSA cryptosystem for any key length. This is why cryptographers are hard at work designing and analyzing "quantum-resistant" public-key algorithms. Currently, quantum computing is too nascent for cryptographers to be sure of what is secure and what isn't. But even assuming aliens have developed the technology to its full potential, quantum computing doesn't spell the end of the world for cryptography. Symmetric cryptography is easy to make quantum-resistant, and we're working on quantum-resistant public-key algorithms. If public-key cryptography ends up being a temporary anomaly based on our mathematical knowledge and computational ability, we'll still survive. And if some inconceivable alien technology can break all of cryptography, we still can have secrecy based on information theory -- albeit with significant loss of capability. At its core, cryptography relies on the mathematical quirk that some things are easier to do than to undo. Just as it's easier to smash a plate than to glue all the pieces back together, it's much easier to multiply two prime numbers together to obtain one large number than it is to factor that large number back into two prime numbers. Asymmetries of this kind -- one-way functions and trap-door one-way functions -- underlie all of cryptography.
