We start from a town that has no internet and reflect on how quickly the last 8 years of progress feel very distant, then discuss the recent extreme examples of companies challenging Net Neutrality. Ballmer says Windows Phones should run Android apps & maybe he’s right?

Google’s Chromebooks make up half of US classroom devices. As parents, are we comfortable with Google having a lifetime of history on our kids?

Headlines

Enabling FreeBSD on AArch64

One of the things the FreeBSD foundation has been dumping money into lately is ARM64 support, but we haven’t heard too much about it – this article should change that
Since it’s on a mainstream ARM site, the article begins with a bit of FreeBSD history, leading up to the current work on ARM64
There’s also a summary of some of the ARM work done at this year’s BSDCan, including details about running it on the Cavium ThunderX platform (which has 48 cores)
As of just a couple months ago, dtrace is even working on this new architecture
Come 11.0-RELEASE, the plan is for ARM64 to get the same “tier 1” treatment as X86, which would imply binary updates for base and ports – something Raspberry Pi users often complain about not having

OpenBSD’s tcpdump detailed

Most people are probably familiar with tcpdump, a very useful packet sniffing and capturing utility that’s included in all the main BSD base systems
This video guide is specifically about the version in OpenBSD, which has gone through some major changes (it’s pretty much a fork with no version number anymore)
Unlike on the other platforms, OpenBSD’s tcpdump will always run in a chroot as an unprivileged user – this has saved it from a number of high-profile exploits
It also has support for the “pf.os” system, allowing you to filter out operating system fingerprints in the packet captures
There’s also PF (and pflog) integration, letting you see which line in your ruleset triggered a specific match
Being able to run tcpdump directly on your router is pretty awesome for troubleshooting

More FreeBSD foundation at BSDCan

The FreeBSD foundation has another round of trip reports from this year’s BSDCan
First up is Kamil Czekirda, who gives a good summary of some of the devsummit, FreeBSD-related presentations, some tutorials, getting freebsd-update bugs fixed and of course eating cake
A second post from Christian Brueffer, who cleverly planned ahead to avoid jetlag, details how he got some things done during the FreeBSD devsummit
Their third report is from our buddy Warren Block, who (unsurprisingly) worked on a lot of documentation-related things, including getting more people involved with writing them
In true doc team style, his report is the most well-written of the bunch, including lots of links and a clear separation of topics (doc lounge, contributing to the wiki, presentations…)
Finally, the fourth one comes to us from Shonali Balakrishna, who also gives an outline of some of the talks
“Not only does a BSD conference have way too many very smart people in one room, but also some of the nicest.”

DragonFly on the Chromebook C720

If you’ve got one of the Chromebook laptops and weren’t happy with the OS it came with, DragonFlyBSD might be worth a go
This article is a “mini-report” on how DragonFly functions on the device as a desktop, and
While the 2GB of RAM proved to be a bit limiting, most of the hardware is well-supported
DragonFly’s wiki has a full guide on getting set up on one of these devices as well

Introducing LiteBSD

We definitely don’t talk about 4.4BSD a lot on the show
LiteBSD is “a variant of [the] 4.4BSD operating system adapted for microcontrollers”
If you’ve got really, really old hardware (or are working in the embedded space) then this might be an interesting hobby project to look info

HardenedBSD announces ASLR completion

HardenedBSD, now officially a full-on fork of FreeBSD, has declared their ASLR patchset to be complete
The latest and last addition to the work was VDSO (Virtual Dynamic Shared Object) randomization, which is now configurable with a sysctl
This post gives a summary of the six main features they’ve added since the beginning
Only a few small things are left to do – man page cleanups, possibly shared object load order improvements

Unlock the reaper

In the ongoing quest to make more of OpenBSD SMP-friendly, a new patch was posted that unlocks the reaper in the kernel
When there’s a zombie process causing a resource leak, it’s the reaper’s job to deallocate their resources (and yes we’re still talking about computers, not horror movies)
Initial testing has yielded positive results and no regressions
They’re looking for testers, so you can install a -current snapshot and get it automatically
An updated version of the patch is coming soon too
A hackathon is going on right now, so you can expect more SMP improvements in the near future

The importance of mentoring

Adrian Chadd has a blog post up about mentoring new users, and it tells the story of how he originally got into FreeBSD
He tells the story of, at age 11, meeting someone else who knew about making crystal sets that became his role model
Eventually we get to his first FreeBSD 1.1 installation (which he temporarily abandoned for Linux, since it didn’t have a color “ls” command) and how he started using the OS
Nowadays, there’s a formal mentoring system in FreeBSD
While he talks about FreeBSD in the post, a lot of the concepts apply to all the BSDs (or even just life in general)

Feedback/Questions

Send questions, comments, show ideas/topics, or stories you want mentioned on the show to feedback@bsdnow.tv
If you’re in or around the Calgary, Alberta area in Canada, there’s an OpenBSD developer speaking event at the Southern Alberta Institute of Technology on July 20th
It’s right after the hackathon, and they’ll be discussing some of the work that was done (maybe with a Q&A session)
We’re looking for some new interviews – get in touch if you’re doing anything cool with BSD that you’d like to talk about (or want to suggest someone else)

A New Tool Against Cyber Threats — Medium

It’s one of the great paradoxes of our Information Age — the very technologies that empower us to do great good can also be used by adversaries to inflict great harm. The same technologies that help keep our military strong are used by hackers in China and Russia to target our defense contractors and systems that support our troops. Networks that control much of our critical infrastructure — including our financial systems and power grids — are probed for vulnerabilities by foreign governments and criminals.

Cyber intrusions and attacks — many of them originating overseas — are targeting our businesses, stealing trade secrets, and costing American jobs. Iranian hackers have targeted American banks. The North Korean cyber attack on Sony Pictures destroyed data and disabled thousands of computers. In other recent breaches that have made headlines, more than 100 million Americans had their personal data compromised, including credit card and medical information.

Living life on the S6 Edge | The Verge

The Galaxy S6 Edge also doesn’t play too nicely with Google’s Material Design. Samsung has my eternal appreciation for following Google’s lead in moving to a cleaner, more minimalist interface, but Material Design emphasizes flatness and geometric regularity, which the Edge’s warping side screens disturb. They create a sort of vignette effect on white pages and are a hindrance rather than a help when editing photos.

Meet the Asus Chromebook Flip, a $249 Chrome OS tablet with a 360-degree hinge | PCWorld

The Chromebook Flip squeezed an adequate supply of connectivity into its slender profile. On one side, you’ll see two USB 2.0 ports, an SD card slot, HDMI, and an audio jack. On the other, you’ll see power and volume buttons, plus the DC power port.

Under the hood you’ll find 2GB of RAM and the Rockchip 3288 CPU. Rockchip, a new partner for Google, brings less expensive, more power-efficient CPUs to the Chromebook lineup. Google also announced new Chromebooks from Haier and Hisense with the same chip. Benchmarks from our hands-on with the new Hisense Chromebook indicate that this processor holds up well compared to older ARM chips.

To that end, one of Google’s newest additions to the lineup of devices, the Chomebit, hawks Chrome OS without even trying to sell a Chromebook laptop.

RadioShack co-branding of stores with Sprint wins court approval | Reuters

The stores are what survived of more than 4,000 outlets after RadioShack went bankrupt in February. Founded in 1921, the chain was a go-to retailer for electronics before becoming increasingly irrelevant in the digital age.

Howto Install Linux on Chromebook

Suggest: ‘Linux on Chromebook how to’ LAS episode

Acer C720 Chromebook – ArchWiki

The Acer C720 Chromebook (and newer Chromebooks in general) features a “legacy boot” mode that makes it easy to boot Linux and other operating systems. The legacy boot mode is provided by the SeaBIOS payload of coreboot. SeaBIOS behaves like a traditional BIOS that boots into the MBR of a disk, and from there into your standard bootloaders like Syslinux and GRUB.

How to run DotA 2 on a Chromebook

Accessing the superuser shell with Chrome OS installed

If you have configured Chrome OS already:

Open a crosh window with Ctrl + Alt + T.
Open a bash shell with the shell command.
Become superuser with sudo bash

Enabling the pre-installed version of SeaBIOS

This method will allow you to access the pre-installed version of SeaBIOS through the Developer Mode screen in coreboot.

Inside your superuser shell enter:
crossystem dev_boot_usb=1 dev_boot_legacy=1
Reboot the machine.

You can now start SeaBIOS by pressing Ctrl + L at the white boot splash screen.

Remove the write-protect screw to Perma-Disable the boot message warning

By removing the bottom panel of the laptop by removing the 12 visible screws and another one underneath the warranty sticker, then separating the plastic starting at the back

Finally completely remove the write-protect screw from the motherboard, which is labelled as #7 in this picture

Setsuna666/elementaryos-chromebook · GitHub

ChromeeOS will install elementary OS (with ChrUbuntu) and apply automatically all the necessary fixes to run elementary OS on Chromebooks. You will be able to boot in ChromeOS or elementary OS on your Chromebook.

Troubleshooting

Legacy Boot Doesn’t Work

Sometimes it’s possible to break the SeaBIOS install in the flash (sometimes doing innocuous things like tweaking the GBB flags). If you do get into such a situation:

Check that dev_boot_legacy is set to 1 when you run crossystem
- If it isn’t, then see the normal Legacy Boot section above
- if it is, then see below

You can safely reset the copy of SeaBIOS in your flash by running (as root):

# chromeos-firmwareupdate --sb_extract /tmp
# flashrom -w /tmp/bios.bin -i RW_LEGACY

Chromebook Acer C720 Running Linux Review:

Brought to you by: System76

Whatever the reason, you may find the paltry offering of a 16GB SSD on the Acer C720 Chromebook to be lacking for some use cases out there. You can pick up a C720P model with 32GB of internal storage — and a touchscreen — for $50 more than the regular C720, but what if you already have one or need more than 32GB? Well, it turns out it’s extremely simple to replace the SSD in the Acer C720, and we’re going to show you how to do it.

Installing Arch Linux on the C720

A longstanding GnuTLS certificate validation botch

Perhaps the biggest irony is that the fix changes a handful of “goto cleanup;” lines to “goto fail;”. It also made other changes to the code (including adding a “fail” label), but the resemblance to the Apple bug is too obvious to ignore. While the two bugs are actually not that similar, other than both being in the certificate validation logic, the timing and look of the new bug does give one pause.

The problem boils down to incorrect return values from a function when there are errors in the certificate.

It is hard to say how far back this bug goes, as the code has been restructured several times over the years, but the GnuTLS advisory warns that all versions are affected.

Emacs, wget, NetworkManager, VLC, Git, and others.

Fedora 20 system, attempting to remove GnuTLS results in Yum wanting to remove 309 dependent packages, including all of KDE, Gnucash, Calligra, LibreOffice, libvirt, QEMU, Wine, and more.

It was a code audit done by GnuTLS founder Nikos Mavrogiannopoulos (at the request of Red Hat, his employer) that discovered the bug.

Critical crypto bug leaves Linux, hundreds of apps open to eavesdropping

Video Acceleration Takes The Backseat On Chrome For Linux

Due to notorious Linux graphics drivers, Google developers working on Chrome/Chromium aren’t looking to enable hardware video acceleration by default anytime soon. The problem ultimately comes down to poor Linux graphics drivers.

Ami Fischman explained in a bug comment yesterday, “There is a history of users disabling the blacklist (entirely) because they want a feature that is disabled. That destabilizes the entire browser, and users frequently forget about this action (and waste time trying to re-stabilize their browser later). If this landed I expect that sooner or later we’d get a rash of blog posts explaining how to get HW decode on linux ‘for free’ (by disabling the GPU blacklist) and the overall result for our Linux userbase would be a worse experience (because the blacklist will never be consulted on their system), not better (b/c they’ll have HW acceleration of h.264 decode). This is a judgement call and I can certainly see how reasonable people can disagree, but this is my personal judgement.”

Ami went on to imply that the VA-API Linux support will never be in good enough shape for Chrome, “We don’t ship code we consider to be permanently ‘experimental’ or ‘beta’, only code we expect to be stable/production-quality eventually, if not at landing. This feature will never graduate to that status, so this CL is effectively shipping a feature that is known to be mostly-broken on most Linux installations.”

Chrome developer Jorge Lucangeli Obes also commented on this report, “Supporting GPU features on Linux is a nightmare (I know from dealing with the GPU sandbox). Enabling this feature should come after thinking how we can make it available without making Chrome on Linux less stable.”

Fedora To Have a “Don’t Ask, Don’t Tell” For Contributors

"The Fedora Project is now going to enforce a “Don’t Ask, Don’t Tell” policy for contributors. What the project’s engineering committee is asking their members to conceal is a contributor’s nationality, country of origin, or area of residence. There’s growing concern about software development contributions coming from export restricted countries by the US (Cuba, Iran, North Korea, Sudan, and Syria) with Red Hat being based out of North Carolina

Developers from Cuba, Iran, North Korea, Sudan & Syria can’t contribute to US based open source projects?

Krita 2.8.0 Released

Some major updates in Calligra office suite are:

The word processor, Words received support for comments
Sheets has better support for pivot tables
Kexi now runs on Windows and about 30 major issues has been fixed in this visual database application.
Flow now supports SVG based stencils.
A thumbnail sketch of Krita 2.8

The 2.8 release marks the debut of several new under-the-hood changes in Krita. The first is a major refactoring of the application’s OpenGL canvas code.

For 2.8 the OpenGL support was brought up to OpenGL 3.1 and OpenGL ES 2.0 compliance (the latter of which enables the tablet-centric “Krita Sketch” variant to run on embedded hardware).

Along the way, Krita’s Windows builds gained OpenGL support as well; 2.8 marks the first version of Krita to be declared stable on Windows

The more interesting improvement for Linux users is an entirely new OpenGL scaling algorithm that offers better quality than the default OpenGL scaling options. The upshot is smoother rendering, especially when zooming in on the canvas.

The new rendering code was written by Kazakov, whose time on the project is funded by the Krita Foundation. Kazakov also undertook the other major piece of plumbing to debut in version 2.8: native support for pressure-sensitive graphics tablets.

OpenBSD automatic installation

A CFT (call for testing) was posted for OpenBSD’s new automatic installer process
Using this new system, you can spin up fully-configured OpenBSD installs very quickly
Allows you to PXE boot the system and load the answer file via HTTP by each machines MAC address, with fallback to a default config file
It will answer all the questions for you and can put files into place and start services
Great for large deployments, help test it and report your findings

FreeNAS install guide and blog posts

A multipart series on YouTube about installing FreeNAS
In part 1, the guy (who is possibly Dracula, with his very Transylvanian accent..) builds his new file server and shows off the hardware
In part 2, he shows how to install and configure FreeNAS, uses IPMI, sets up his pools
He pronounces gigabytes as jiggabytes and it’s hilarious
We’ve also got an unrelated blog post about a very satisfied FreeNAS user who details his setup
As well as another blog post from our old pal Devin Teske about his recent foray into the FreeNAS development world

FreeBSD 10.0-RC5 is out

Another, unexpected RC is out for 10.0
Includes an ABI change, you must recompile/reinstall all ports/packages if you are upgrading from a previous 10.0-RC
Minor fixes included, please help test and report any bugs
You can update via freebsd-update or from source
Hopefully this will be the last one before 10.0-RELEASE, which has tons of new features we’ll talk about
It’s been tagged -RELEASE in SVN already too!

OpenBSD 5.5-beta is out

Theo updated the branch status to 5.5-beta
A list of changes is available
Help test and report any bugs you find
Lots of rapid development with signify (which we mentioned last week), the beta includes some “test keys”
Does that mean it’ll be part of the final release? We’ll find out in May.. or when we interview Ted (soon)

This episode was brought to you by

iX doesn’t just make big servers for work, they also make little servers for home. The FreeNAS Mini is a compact little rig that will take up to 4 drives and makes a great home storage server.

Blog post from our friend Damien Miller
This new feature allows clients to canonicalize unqualified domain names
SSH will know if you typed “ssh bsdnow” you meant “ssh bsdnow.tv” with new config options
This will help clean up some ssh configs, especially if you have many hosts
Should make it into OpenSSH 6.5, which is “due really soon”

Cron Overview and Tricks:

Brought to you by: System76

Cron is a daemon that executes scheduled commands. Cron searches its spool area (/var/spool/cron/crontabs) for crontab files.

Note that crontabs in this directory should not be accessed directly – the crontab command should be used to access and update them.
