Runs Linux

• Soda Can Solar Collector

The SolarAir is a solar heat collector made DIY, with very low cost materials, mainly Soda Cans.
The hot air is used to to heat the house, everyday when there is some sun, even if it is freezing outside, thus lowering utility bills, and lowering CO2 footprint.

Weekly Spotlight

• Password Generation on Linux

apg generates several random passwords. It uses several password generation algorithms (currently two) and a built-in pseudo random number generator.
Default algorithm is pronounceable password generation algorithm designed by Morrie Gasser and described in A Random Word Generator For Pronounceable Passwords National Technical Information Service (NTIS) AD-A-017676. The original paper is very old and had never been put online, so I have to use NIST implementation described in FIPS-181.

Microsoft Is Buying Mobile Cross-Platform Development Company Xamarin

Microsoft announced today that it has acquired Xamarin, a company that allows developers to build fully native apps across several platforms from a single shared code base.

Linux users campaign after Microsoft ‘neglects’ Skype with a week of downtime-

The _open letter to Microsoft_said: “It was a shitty move to not update the client for three years, which resulted in this, mostly. It was annoying that you ignored almost every tweet to @SkypeSupport about issues with Skype for Linux. But it is absolutely disgraceful that you dropped the Linux client BEFORE any alternatives are available and without telling your users.”

GPL Violations Related to Combining ZFS and Linux

However, our conclusion is simple: Conservancy and the Linux copyright
holders in the GPL Compliance Project for
Linux Developers believe that distribution of ZFS binaries is a GPL
violation and infringes Linux’s copyright. We are also concerned that it may
infringe Oracle’s copyrights in ZFS. As such, we again ask Oracle to respect
community norms against license proliferation and simply relicense its
copyrights in ZFS under a GPLv2-compatible license.

TechSNAP Take on SFC ZFS Finding

• Canonical accused of violating GPL with ZFS-in-Ubuntu 16.04 plan

Canonical’s counter-argument is that “The CDDL cannot apply to the Linux kernel because zfs.ko is a self-contained file system module — the kernel itself is quite obviously not a derivative work of this new file system.”

• Report from the VMware GPL court hearing | LaForge’s home page

• VMware is using parts of the Linux kernel in their proprietary ESXi
  product, including the entire SCSI mid-layer, USB support, radix tree
  and many, many device drivers.
  • as is generally known, Linux is licensed under GNU GPLv2, a
    copyleft-style license.
  • VMware has modified all the code they took from the Linux kernel and
    integrated them into something they call vmklinux.
  • VMware has modified their proprietary virtualization OS kernel
    vmkernel with specific API/symbol to interact with vmklinux
  • at least in earlier versions of ESXi, virtually any block device
    access has to go through vmklinux and thus the portions of Linux
    they took
  • vmklinux and vmkernel are dynamically linked object files that are
    linked together at run-time
  • the Linux code they took runs in the same execution context (address
    space, stack, control flow) like the vmkernel.

• The Linux Kernel, CDDL and Related Issues – Software Freedom Law Center

When, in this mode of employment, the CDDL-licensed code implementing the filesystem is combined with the module-specific translation layer and the result is then statically or dynamically linked into the Linux kernel, the resulting binary is licensed to all users under the terms of GPLv2, and only GPLv2, as the license requires. This happens because CDDL gives permission for binary forms of the code it licenses to be released under any license, and the license terms in effect are those of GPLv2. The making of the binary itself does not result in infringement of the kernel copyrights, or a violation of GPLv2’s terms.

• Debian Devs Realized They Were Shipping Pre-Built Nvidia Module, Breaking GPL

“The Nvidia-graphics-modules provides pre-compiled non-free kernel modules. Several lawyers and people believe this to be a violation of the GPL license used by the kernel. This interpretation is consistent with our position on ZFS modules, which we also ship in source code only. As such, the work is not distributable and should be removed from the archive in all suites, ASAP,” Julian Andres Klode said.

Parse Shutdown Savings

If the Parse platform is still appropriate or your app, then the migration process is very doable and something we’d be happy to help with. In fact we are running a promotion from now until April 15th, 2016 to migrate your app for iOS and/or Android to a Parse-powered server for a flat one time fee of $500.

Headlines

FreeBSD foundation\’s 2013 fundraising results

• The FreeBSD foundation finally counted all the money they made in 2013
• $768,562 from 1659 donors
• Nice little blog post from the team with a giant beastie picture
• \”We have already started our 2014 fundraising efforts. As of the end of January we are just under $40,000. Our goal is to raise $1,000,000. We are currently finalizing our 2014 budget. We plan to publish both our 2013 financial report and our 2014 budget soon.\”
• A special thanks to all the BSD Now listeners that contributed, the foundation was really glad that we sent some people their way (and they mentioned us on Facebook)

OpenSSH 6.5 released

• We mentioned the CFT last week, and it\’s finally here!
• New key exchange using elliptic-curve Diffie Hellman in Daniel Bernstein\’s Curve25519 (now the default when both clients support it)
• Ed25519 public keys are now available for host keys and user keys, considered more secure than DSA and ECDSA
• Funny side effect: if you ONLY enable ed25519 host keys, all the compromised Linux boxes can\’t even attempt to login
• New bcrypt private key type, 500,000,000 times harder to brute force
• Chacha20-poly1305 transport cipher that builds an encrypted and authenticated stream in one
• Portable version already in FreeBSD -CURRENT, and ports
• Lots more bugfixes and features, see the full release note or our interview with Damien
• Work has already started on 6.6, which can be used without OpenSSL!

Crazed Ferrets in a Berkeley Shower

• In 2000, MWL wrote an essay for linux.com about why he uses the BSD license: \”It’s actually stood up fairly well to the test of time, but it’s fourteen years old now.\”
• This is basically an updated version about why he uses the BSD license, in response to recent idiocy from Richard Stallman
• Very nice post that gives some history about Berkeley, the basics of the BSD-style licenses and their contrast to the GNU GPL
• Check out the full post if you\’re one of those people that gets into license arguments
• The takeaway is \”BSD is about making the world a better place. For everyone.\”

OpenBSD on BeagleBone Black

• Beaglebone Blacks are cheap little ARM devices similar to a Raspberry Pi
• A blog post about installing OpenBSD on a BBB from.. our guest for today!
• He describes it as \”everything I wish I knew before installing the newly renamed armv7 port on a BeagleBone Black\”
• It goes through the whole process, details different storage options and some workarounds
• Could be a really fun weekend project if you\’re interested in small or embedded devices
