Panamax taught me a lot about Docker, and caused me to publish my first two images to the Docker registry, which is more than I expected to gain from trying it out. I’m not sure I’m the target audience – I don’t think I’d want to run production Docker apps under it on a headless server (at least until it’s more stable), which suggests that its main use is as an easy way to experiment with the development of containerized systems. But the friction introduced by the extra CoreOS host seems too great for it to be an awesome development platform for me. I think it’s a solvable problem – if the team can find a way to make the network port forwarding and the filesystem NFS sharing be automatic, rather than manual, and to work with ecryptfs on Ubuntu, it would make a massive difference.
I am impressed with the newfound ability to help someone launch a database-backed Django app without using any terminal commands, even if they’re on Windows and have no kind of dev environment, and would consider recommending Panamax for someone in that situation. Ultimately, maybe what I’ll get out of Panamax is a demystification of Docker’s orchestration concepts. That’s still a pretty useful experience to have.
The full power of digital photography lies in knowing how to manipulate RAW images. When you shoot RAW you get the highest-quality images, and the most editing headroom for repairs and enhancements. Raw Therapee is a wonderful cross-platform RAW image processor. Use it for noise reduction, pulling details out of shadows, fine-grained sharpening, color adjustment, color management, contrast, luminance, brightness, gamma, and hue corrections, convert to black and white, exposure corrections, distortion, chromatic aberration, and vignetting repairs, apply lens correction profiles, and about a skillion more features.
If you are a Fedora Eclipse user, then you're probably saddened since the release of Eclipse Luna (4.4) because you are still using Eclipse Kepler (4.3) on Fedora 20.
Well, be saddened no longer because Eclipse Luna is now available for Fedora 20 as a software collection!
A software collection is simply a set of RPMs whose contents are isolated from the rest of your system such that they do not modify, overwrite or otherwise conflict with anything in the main Fedora repositories. This allows you install multiple versions of a software stack side-by-side, without them interfering with one another. More can be read about this mechanism on the software collections website.
The Eclipse Luna software collection lives in a separate yum repository, which must be configured by clicking on this link to install the release package.
The product, called ExaGear Desktop, runs x86 operating systems on top of hardware devices using ARMv7 CPUs. That's significant because x86 software, which is the kind that runs natively on most computing platforms today, does not generally work on ARM hardware unless software developers undertake the considerable effort of porting it. Since few are likely to do that, having a way to run x86 applications on ARM devices is likely to become increasingly important as more ARM-based tablets and portable computers come to market.
That said, the ExaGear Desktop, which Eltechs plans to make available next month, currently has some steep limitations. First, it only supports Ubuntu Linux. And while Eltechs said support for additional Linux distributions is forthcoming, there's no indication the product will be able to run x86 builds of Windows on ARM hardware, a feat that is likely to be in much greater demand than Linux compatibility.
