Linux Mint vs. Ubuntu: the Best Option? For the last few years, there has been something of a popularity contest between two well-known Linux distros: Linux Mint and Ubuntu. Both of these distributions share the same code base, as Ubuntu is based on Debian and Linux Mint is based on Ubuntu. In both instances, the distributions took the foundation that Debian built, then added their own flavor to make it more user friendly. The similarities between the two distributions go even further, in that Ubuntu packages work flawlessly on Linux Mint, just as Ubuntu PPAs work well on Linux Mint. When Linux Mint was first being developed, the degree of separation from Ubuntu was very minimal. For this article, I’ll tap into my own experiences with both distributions over the years. Easy isn't a dirty word All too often, I hear the word "easy" being tossed around as if it's a bad word when describing Linux distributions. In recent years, I've actually found the two distributions shift further apart than ever before.
Cafe Arcane » Blog Archive » Vargo Titanium Wood Stove Anyone that has seen my gear list know that I’m a pretty satisfied user of ultralight canister stoves. The combination of cleanliness, control and convenience usually meets my needs 9 times out of 10 when hiking and camping. I do have a strong admiration for the weight, design and ingenuity of many of the other stove concepts used in hiking; in particularly the alcohol stoves and traditional fuel stoves (which used foraged combustibles). While perusing the goodies over at Go Fast and Light, I came across an offering by Vargo. One of the drawbacks of traditional materials stove is that they tend to be large. Vargo’s Titanium Wood Stove addresses this issue with an ingenious folding and locking design that makes the stove as flat as a piece of cardboard when not in use. The item appears to be enjoying significant popularity and is regularly sold out but they do accept back orders.
Valve: Linux More Viable Than Windows 8 for Gaming In a presentation at Ubuntu Developer Summit currently going on in Denmark, Drew Bliss from Valve said that Linux is becoming more viable platform as an alternative to Windows 8. Windows 8 ships with its own app store and it is moving away from an open platform model. Some other points from the talk: Steam client is running nicely on Ubuntu and many developers have approached them with good game products.Cooperation with Canonical has been good.Ubuntu is preferred platform as it has a large user base and good community support with a strong company like Canonical behind it. Linux has everything they need: good OpenGL, pulseaudio, OpenAL and input support.New Source engine games will be available for Linux.No firm time frame for Steam Linux release, but soon.Copy protection is up to the game publishers. Drew announced that anyone with a Launchpad account attending UDS will be given Steam access through a beta key.
