Interview: Mesosphere’s Ben Hindman on the Need for a Data Center OS

One of the most interesting new companies leveraging an open source Apache project has to be Mesosphere, which OStatic covered in a recent post. The company offers a “data center operating system” (DCOS) built on the open source Apache Mesos project, and has announced a recent round of $36M in Series B funding. New investor Khosla Ventures led the round, with additional investments from Andreessen Horowitz, Fuel Capital, SV Angel and others.

According to Mesosphere’s leaders, the tech industry now needs a new type of operating system to automate the various tools used in the agile IT era.  They argure that developers and operators don’t need to focus on individual virtual or physical machines but can easily build and deploy applications and services that span entire datacenters.

Local MirageOS Development With Xen and Virtualbox

MirageOS is a library operating system. An application written for MirageOS is compiled to an operating system kernel that only contains the specific functionality required by the application – a unikernel. The MirageOS unikernels can be compiled for different targets, including standalone VMs that run under Xen. The Xen unikernels can be deployed directly to common cloud services such as Amazon EC2 and Linode.

I have done a lot of MirageOS development for Xen lately and it can be inconvenient to have to rely on an external server or service to be able to run and debug the unikernel. As an alternative I have set up a VM in Virtualbox with a Xen server. The MirageOS unikernels then run as VMs in Xen, which itself runs in a VM in Virtualbox. With the “Host-only networking” feature in Virtualbox the unikernels are accessible from the host operating system, which can be very useful for testing client/server applications. A unikernel that hosts a web page can for example be tested in a web browser in the host OS. I am hoping that this setup may be useful to others so I am documenting it in this blog post.

Manjaro Xfce 0.9.0 Pre1 Shows How Open Source Collaboration Works

Manjaro Xfce 0.9.0 Pre1, a Linux distribution based on well-tested snapshots of the Arch Linux repositories and 100% compatible with Arch, is now ready for testing and download.

The Manjaro developers have announced a while ago that they were working on the next version in the series, although it looks like they are not ready to take the big step towards the dreaded version 1.0. The latest stable version is now 0.8.11 and the one after that was 0.8.10, so we can consider this to be an evoluti… (read more)

Unzip Vulnerability Closed in Ubuntu OSes

Canonical has announced that an unzip exploit has been found and fixed for Ubuntu 14.10, Ubuntu 14.04 LTS, Ubuntu 12.04 LTS, and Ubuntu 10.04 LTS operating systems.

As the name suggests, the unzip library is the one that ensures users can decompress zip files, and finding exploits and vulnerabilities for it is rather unusual. Nonetheless, such vulnerability was found and it’s now OK, a patch later. The devs were saying that unzip could have been made to crash or run programs, if the user were… (read more)

Cinnamon 2.6 to Get Systemd Support

The Linux Mint developers are not only working on the next iteration of the operating system, they are also trying to improve upon the Cinnamon desktop environment, which is also built by them.

The Linux Mint Cinnamon edition is the most used flavor for this distro, although the MATE follows close behind. The fact that the Linux Mint team is also making the desktop environment means that users will probably get the best integration of this software stack into an operating system. On the other… (read more)

Linus Torvalds Releases Linux Kernel 3.19 RC5, Says Go Forth and Test

Linus Torvalds has released yet another update for the Linux kernel 3.19 branch and this is the fifth Release Candidate in the series. The development cycle is getting closer to its end and that can be observed from the changelog.

The Linux development cycle is never this calm, but it looks like the 3.19 branch turned out to be pretty uneventful. This seldom happens and Linus is making the best of it by providing updates pretty fast. If nothing changes in the meantime, the next iteration of t… (read more)
