Smart Gimp Tricks

The Quickmask for adjusting selections: I’m a born-again Quickmask evangelist, because I went so long without realizing that it was there, and it makes selections so much easier.

Decomposing an image and using the components as a mask to select part of an image—that’s an easy way to select skies and get rid of a drab overcast sky, or to change or enhance the color of the sky.

Using the Dodge/Burn tool to make a background really white, for when you want an object to stand out and make the background go away. It can be a lot easier than selecting or erasing.

Noah Hit Something on the Head

“I wish Ubuntu would just use GNOME, and go back to trying to contribute useful bits.”

Now, I have a few extensions installed, but the way I use GNOME isn’t much different from how someone would use Unity; I keep the Dash up at all times, I have those pesky tray apps up in the corner, and so on. This is so close to how I used to work in Unity, OS X, etc., that I’m puzzled at why GNOME gets treated like the red-headed stepchild sometimes.

Now, I know that once in a while the GNOME dev team decides to go off the deep end (Let’s make the filemanager work like old-school Finder and do that by default! Hell, let’s override users’ pre-existing settings, that’s how good it is!) but overall GNOME just keeps getting better.

Windows Secureboot Causes a Mess

I just made a potentially costly mistake: we nuked and repaved my friend’s brand new Lenovo Yoga 500 with Linux… without booting into Windows to disable SecureBoot explicitly. He didn’t want to accept the EULA; and we successfully booted into USB key (Ubuntu MATE 15.10, Ubuntu w/Unity 15.04) so we thought we would just go ahead.

I thought Ubuntu would have been candidate, but apparently not. Is this the correct way? Which distros would work? We tried installing and booting into Ubuntu Unity 15.04 (which is supposed to have the appropriate signature) but after install and reboot, we get the above. Given that Windows has been obliterated at this point, what options do I have?

Unfortunately, he’s leaving in just over a week, so if the conclusion ends up being “install Windows to do this” I’ll take it….. but I’d rather not!

Ever Heard of FriendOS?

I heard yesterday about Friendos. It looks like this: https://youtu.be/Y5n0f5DSbSM?t=16m14s , so it’s like Amiga Workbench in the browser powered by a Linux backend. They releasing public beta as open source this week.It will be able to run both thml5 and native applications. Their website is a little enigmatic right now:

Numbers don’t lie—it’s time to build your own router

I’ve noticed a trend lately. Rather than replacing a router when it literally stops working, I’ve needed to act earlier—swapping in new gear because an old router could no longer keep up with increasing Internet speeds available in the area. (Note, I am duly thankful for this problem.) As the latest example, a whole bunch of Netgear ProSafe 318G routers failed me for the last time as small businesses have upgraded from 1.5-9mbps traditional T1 connections to 50mbps coax (cable).

A lot of you are probably muttering, “right, pfSense, sure.” Some of you might even be thinking about smoothwall or untangle NG. I played with most of the firewall distros out there, but I decided to go more basic, more old school: a plain, CLI-only install of Ubuntu Server and a few iptables rules.

Admittedly, this likely isn’t the most practical approach for every reader, but it made sense for me. I have quite a bit of experience finessing iptables and the Linux kernel itself for high throughput at Internet scale, and the fewer shiny features and graphics and clicky things that are put between me and the firewall table, the less fluff I have to get out of the way and the fewer new not-applicable-in-the-rest-of-my-work things I have to learn. Any rule I already know how to create in iptables to manage access to my servers, I also know how to apply to my firewall—if my firewall’s running the same distro as my servers are.

Cumulus Networks

Cumulus Networks is a system software company founded with the principle of enabling high capacity networks that are easy to deploy and affordable. Led by networking experts and innovators from Cisco and VMware, we provide great networking for layer 2, layer 3 and overlay architectures supported by improved economics and a robust ecosystem — a modern alternative to proprietary vendor-locked stacks that constrain IT innovation.

Gnome Core Apps

It would appear that the GNOME developers are currently in the process of revisiting the desktop environment’s moduleset and defining a clear set of core apps, which should form the default user experience in upcoming releases of the GNOME desktop (most probably starting with GNOME 3.20, which should be available in spring 2016).

At the moment of writing this article, the GNOME developers have only managed to announce that the Cheese webcam viewer app has been integrated as a core GNOME app as it is required by the GNOME Control Center, GNOME Initial Setup and GNOME Contacts components. They are also in talks with the developers of the Gedit text editor to make it a core app too.

Furthermore, the GNOME Color Manager component will also be pushed to the core apps moduleset, as the GNOME Control Center software requires it. However, the GNOME developers will also define a set of non-core apps, which they don’t recommend GNU/Linux OS vendors to include in their distributions when using the GNOME desktop environment by default.

Phoenix OS

Google Android may have been developed as a smartphone operating system (and later ported to tablets, TVs, watches, and other platforms), but over the past few years we’ve seen a number of attempts to turn it into a desktop operating system.

One of the most successful has been Remix OS, which gives Android a taskbar, start menu, and an excellent window management system. The Remix OS team has also generated a lot of buzz over the past year, and this week the operating system gained a lot of new alpha testers thanks to a downloadable version of Remix OS that you can run on many recent desktop or notebook computers.

But Remix OS isn’t the only game in town. Phoenix OS is another Android-as-desktop operating system, and while it’s still pretty rough around the edges, there are a few features that could make it a better option for some testers.

Headlines

New PAE support in OpenBSD

OpenBSD has just added Physical Address Extention support to the i386 architecture, but it’s probably not what you’d think of when you hear the term
In most operating systems, PAE’s main advantage is to partially circumvent the 4GB memory limit on 32 bit platforms – this version isn’t for that
Instead, this change specifically allows the system to use the No-eXecute Bit of the processor for the userland, further hardening the in-place memory protections
Other operating systems enable the CPU feature without doing anything to the page table entries, so they do get the available memory expansion, but don’t get the potential security benefit
As we discussed in a previous episode, the AMD64 platform already saw some major W^X kernel and userland improvements – the i386 kernel reworking will begin shortly
Not all CPUs support this feature, but, if yours supports NX, this will improve upon the previous version of W^X that was already there
The AMD64 improvements will be in 5.7, due out in just a couple days as of when we’re recording this, but the i386 improvements will likely be in 5.8

Booting Windows in bhyve

Work on FreeBSD’s bhyve continues, and a big addition is on the way
Thus far, bhyve has only been able to boot operating systems with a serial console – no VGA, no graphics, no Windows
This is finally changing, and a teasing screenshot of Windows Server was recently posted on Twitter
Graphics emulation is still in the works; this image was taken by booting headless and using RDP
A lot of the needed code is being committed to -CURRENT now, but the UEFI portion of it requires a bit more development (and the aim for that is around the time of BSDCan)
Not a lot of details on the matter currently, but we’ll be sure to bring you more info as it comes out
Are you more interested in bhyve or Xen on FreeBSD? Email us your thoughts

MidnightBSD 0.6 released

MidnightBSD is a smaller project we’ve not covered a lot on the show before
It’s an operating system that was forked from FreeBSD back in the 6.1 days, and their focus seems to be on ease-of-use
They also have their own, smaller version of FreeBSD ports, called “mports”
If you’re already using it, this new version is mainly a security and bugfix release
It syncs up with the most recent FreeBSD security patches and gets a lot of their ports closer to the latest versions
You can check their site for more information about the project
We’re trying to get the lead developer to come on for an interview, but haven’t heard anything back yet

OpenBSD rewrites the file utility

We’re all probably familiar with the traditional file command – it’s been around since the 1970s
For anyone who doesn’t know, it’s used to determine what type of file something actually is
This tool doesn’t see a lot of development these days, and it’s had its share of security issues as well
Some of those security issues remain unfixed in various BSDs even today, despite being publicly known for a while
It’s not uncommon for people to run file on random things they download from the internet, maybe even as root, and some of the previous bugs have allowed file to overwrite other files or execute code as the user running it
When you think about it, file was technically designed to be used on untrusted files
OpenBSD developer Nicholas Marriott, who also happens to be the author of tmux, decided it was time to do a complete rewrite – this time with modern coding practices and the usual OpenBSD scrutiny
This new version will, by default, run as an unprivileged user with no shell, and in a systrace sandbox, strictly limiting what system calls can be made
With these two things combined, it should drastically reduce the damage a malicious file could potentially do
Ian Darwin, the original author of the utility, saw the commit and replied, in what may be a moment in BSD history to remember
It’ll be interesting to see if the other BSDs, OS X, Linux or other UNIXes consider adopting this implementation in the future – someone’s already thrown together an unofficial portable version
Coincidentally, the lead developer and current maintainer of file just happens to be our guest today…

News Roundup

GSoC-accepted BSD projects

The Google Summer of Code people have published a list of all the projects that got accepted this year, and both FreeBSD and OpenBSD are on that list
FreeBSD’s list includes: NE2000 device model in userspace for bhyve, updating Ficl in the bootloader, type-aware kernel virtual memory access for utilities, JIT compilation for firewalls, test cluster automation, Linux packages for pkgng, an mtree parsing and manipulation library, porting bhyve to ARM-based platforms, CD-ROM emulation in CTL, libc security extensions, gptzfsboot support for dynamically discovering BEs during startup, CubieBoard support, a bhyve version of the netmap virtual passthrough for VMs, PXE support for FreeBSD guests in bhyve and finally.. memory compression and deduplication
OpenBSD’s list includes: asynchronous USB transfer submission from userland, ARM SD/MMC & controller driver in libsa, improving USB userland tools and ioctl, automating module porting, implementing a KMS driver to the kernel and, wait for it… porting HAMMER FS to OpenBSD
We’ll be sure to keep you up to date on developments from both projects
Hopefully the other BSDs will make the cut too next year

FreeBSD on the Gumstix Duovero

If you’re not familiar with the Gumstix Duovero, it’s an dual core ARM-based computer-on-module
They actually look more like a stick of RAM than a mini-computer
This article shows you how to build a FreeBSD -CURRENT image to run on them, using crochet-freebsd
If anyone has any interesting devices like this that they use BSD on, write up something about it and send it to us

EU study recommends OpenBSD

A recent study by the European Parliament was published, explaining that more funding should go into critical open source projects and tools
This is especially important, in all countries, after the mass surveillance documents came out
“[…] the use of open source computer operating systems and applications reduces the risk of privacy intrusion by mass surveillance. Open source software is not error free, or less prone to errors than proprietary software, the experts write. But proprietary software does not allow constant inspection and scrutiny by a large community of experts.”
The report goes on to mention users becoming more and more security and privacy-aware, installing additional software to help protect themselves and their traffic from being spied on
Alongside Qubes, a Linux distro focused on containment and isolation, OpenBSD got a special mention: “Proactive security and cryptography are two of the features highlighted in the product together with portability, standardisation and correctness. Its built-in cryptography and packet filter make OpenBSD suitable for use in the security industry, for example on firewalls, intrusion-detection systems and VPN gateways”
Reddit, Undeadly and Hacker News also had some discussion, particularly about corporations giving back to the BSDs that they make use of in their infrastructure – something we’ve discussed with Voxer and M:Tier before

FreeBSD workflow with Git

If you’re interested in contributing to FreeBSD, but aren’t a big fan of SVN, they have a Github mirror too
This mailing list post talks about interacting between the official source repository and the Git mirror
This makes it easy to get pull requests merged into the official tree, and encourages more developers to get involved

Freya on a Mac

Your Mac must not have a Core 2 duo or Solo (or older) processor – only the past couple years of Macs, which have 64-bit EFI, are supported.

Dual Boot Arch and Mac OS X

This tutorial is pretty specific to my latest configuration, but it seems like there might be some people out there who could benefit from my experience. If you have a [1] Macbook Pro 8,2 (the 8,3 model should work as well), with [2] two internal hard drives, and want to [3] dual boot OS X and Arch Linux, utilizing [4] whole disk encryption in both systems… you’re in the right place!

There won’t be much explanation here because most of the in depth explanation has already been described in previous posts. They are linked below in case you get lost for reference to provide additional direction in case you get lost.

The rEFInd Boot Manager

This page describes rEFInd, my fork of the rEFIt boot manager for computers based on the Extensible Firmware Interface (EFI) and Unified EFI (UEFI). Like rEFIt, rEFInd is a boot manager, meaning that it presents a menu of options to the user when the computer first starts up, as shown below.

rEFInd – ArchWiki

rEFInd is a UEFI boot manager. It is a fork of the no-longer-maintained rEFIt and fixes many issues with respect to non-Mac UEFI booting. It is designed to be platform-neutral and to simplify booting multiple OSes.

gummiboot

gummiboot is a simple UEFI boot manager which executes configured EFI images. The default entry is selected by a configured pattern (glob) or an on-screen menu.

TimeShift

TimeShift for Linux is a application that provides functionality similar to the System Restore feature in Windows and the Time Machine tool in Mac OS. TimeShift protects your system by taking incremental snapshots of the file system at regular intervals. These snapshots can be restored later to bring your system to the exact state it was in at the time when the snapshot was taken.

Snapshots are taken using rsync and hard-links. Common files are shared between snapshots which saves disk space. Each snapshot is a full system backup that can be browsed with a file manager.

It’s an open-source world: 78 percent of companies run open-source software

2015 Future of Open Source Survey Results from Black Duck Software

78 percent of respondents said their companies run part or all of its operations on OSS and 66 percent said their company creates software for customers built on open source. This statistic has nearly doubled since 2010, when 42 percent of respondents in the Future of Open Source survey five years ago said that they used open source in the running of their business or their IT environments. This is an all-time high.

93 percent said their organization’s use of open source increased or remained the same in the past year.

64 percent of companies currently participate in open source projects – up from 50 percent in 2014. Over the next 2-3 years, 88 percent are expected to increase contributions to open source projects.

Open source has become the default approach for software with more than 66 percent of respondents saying they consider OSS before other options.

Chrome Starts Pushing Java off the Web

Chrome 42, released to the stable channel today, will take a big step toward pushing old browser plugins, including Java and Silverlight, off the Web. Those plugins use a 1990s-era API called NPAPI (“Netscape Plugin API”) to extend the browser, and with Chrome 42, that API is now off by default.

ZFS may be officially included in Debian

Libdvdcss and ZFS soon in Debian?

We received legal advice from Software Freedom Law Center about the
inclusion of libdvdcss and ZFS in Debian, which should unblock the
situation in both cases and enable us to ship them in Debian soon.

Unfortunately they\’re only for subscribers, so you\’ll have to wait until next month when we have Chris on the show to talk about pfSense!

FreeBSD on Google Compute Engine

Recently we mentioned some posts about getting OpenBSD to run on GCE, here\’s the FreeBSD version
Nice big fat warning: \”The team has put together a best-effort posting that will get most, if not all, of you up and running. That being said, we need to remind you that FreeBSD is being supported on Google Compute Engine by the community. The instructions are being provided as-is and without warranty.\”
Their instructions are a little too Linuxy (assuming wget, etc.) for our taste, someone should probably get it updated!
Other than that it\’s a pretty good set of instructions on how to get up and running
