Linux on amd64

Filed under

You'll probably find that linux is probably the OS with the most native amd64 (x86_64) users. BSD variants and Windows mostly have poor to no amd64 support and/or a smaller user base any way. However, there are still a few drawbacks compared to linux on 32-bit x86.

Drawbacks ? Where ? Why ?

Nowadays, there is a lot of software linux users are accustomed to use that is available in binary form for the intel x86 platform only. There are big commercial applications like VMWare or games like Doom III. But there are also small freeware pieces of software, the most common probably being Java and the Macromedia Flash plugin. Using x86-only plugins on amd64 linux natively is impossible since the web browser and plugin must link directly. There are workarounds forkonqueror, but not everyone wants to use konqueror for every day web browsing. Many people also like watching videos in new wmv formats, which is currently only possible with the binary-only w32codecs. Some open source programs do not work in 64-bit space either; the most notable being

So why do people use it then ?

One word: speed. People like it and linux applications can often give you more of it when they are given 64-bit memory access - more even when, as usual in gentoo amd64, they are optimized for the specific processor you are running. Since the amd64 processor can run 32bit x86 code, there are also workarounds that allow you to run all the applications above on amd64 linux, although sometimes with minor tradeoffs. In the setup described below, I can run firefox and comes up in a x86 flash-capable firefox. This article is ment to explain how I did it.

So, how ?

    An Indigogo campaign was recently launched for the Turis Omnia, promising backers a high-security, high-performance, open-source router. “With powerful hardware, Turris Omnia can handle gigabit traffic and still be able to do much more,” the company said. “You can use it as a home server, NAS, printserver, and it even has a virtual server built-in.”

  • PuppetLabs Introduces Application Orchestration
    Everybody loves Puppet! Or at the very least, an awful lot of people USE Puppet and in the IT world, “love” is often best expressed by the opening of one’s wallet. I know, in the FOSS world wallets are unnecessary, and Puppet does indeed have an Open Source version. However, once one gets to enterprise-level computing, a tool designed for enterprise scale is preferable and usually there is a cost associated. Puppet was originally started as an open source project by Luke Kanies in 2005, essentially out of frustration with the other configuration management products available at the time. Their first commercial product was released in 2011, and today it is the most widely used configuration management tool in the world with about 30,000 companies running it. According to our own surveys, better than 60% of Linux Journal readers use some form of Puppet already and you must like it too as it regularly finishes at or near the top in Readers’ Choice awards.

Ubuntu 16.04 LTS Continues To Focus On The Linux 4.4 Kernel

Ubuntu's kernel team continues to be focused on having Linux 4.4 for Ubuntu 16.04. Linux 4.4 is their target for the "Xenial Xerus" since Ubuntu 16.04 is to be a Long-Term Support release and the upstream 4.4 kernel is also being maintained as a long-term release too. Additionally, Linux 4.5 would come too close to the April debut of Ubuntu 16.04 that the developers wouldn't feel comfortable, particularly for an LTS release. Read more

Will Steam Machine Solve Linux’s Gaming Woes?

The Steam machine is now publicly on sale as of last week, but it’s not off to the best start. A couple of weeks ago, Ars Technica compared the performance of games when running on Valve’s Linux based SteamOS and Windows 10. Six Valve games were tested on a single machine and results showed a 21 to 58 percent frame rate drop when running on Linux. While only six games were tested out of an entire collection of around 1,800 available titles, the games used Valve’s own Source engine, which is designed for Linux and SteamOS. Valve had previously stated that Steam games run faster on Linux, so it was expected that any of Valve’s own Source engine games would run smoothly. Read more
