Xorg – Jupiter Broadcasting

Electron is simply an accessible open-source app development framework. It lets web developers create desktop apps using the technologies they’re already familiar with, like JavaScript, HTML, and CSS.

This angle — low barrier to entry — is why Electron is proving so popular, and so quickly. Developers who might never have made a desktop app can now push the envelope, get creative, and bring their ideas to life using existing skills.

Screen sharing in Plasma wayland session

One of the important missing features in Plasma wayland session is without a doubt possibility to share your screen or record you screen. To support this you need help of the compositor and somehow deliver all needed information to the client (application), in ideal way something what can be used by all DEs, such as Gnome. Luckily, this has been one of the primary goals of Pipewire, together with support for Flatpak.

Using this API, applications can now have access to your screen content on Wayland sessions or in case they are running in sandbox. With various backend implementation, like xdg-desktop-portal-kde or xdg-desktop-portal-gtk, they just need to support one API to target all desktops.

the client first needs to create a session between him and xdp (xdg-desktop-portal) backend implementation, user then gets a dialog with a screen he would like to share and starts screen sharing.

Should allow for support of OBS
Should support multiple displays

Ubuntu 18.04 – No GTK Theme

As many of you know, the “CommuniTheme” (as it’s currently known) is shaping up to be something pretty special. A canny crop of community creators have carefully adapted the ditched designs of the Unity 8 desktop into an attractive, real, and pretty reliable working theme.
But alas their work will not be part of Ubuntu 18.04 LTS, due for release on April 26, 2018.
The decision is a sad one, but it means the Ambiance GTK theme will continue to live on until 2023, having been first introduced back in 2010.

Notepadqq

It helps developers by providing all you can expect from a general purpose text editor, such as syntax highlighting for more than 100 different languages, code folding, color schemes, file monitoring, multiple selection and much more.
You can search text using the power of regular expressions. You can organize documents side by side. You can use real-time highlighting to find near identifiers in no time

Simon

Simon is an open source speech recognition program that can replace your mouse and keyboard. The system is designed to be as flexible as possible and will work with any language or dialect.

ThinkPad Community

We often see people funneling their passion into keeping beloved devices in operation long past their manufacturer’s intent. These replacement Thinkpad motherboards (translated) bring old (yet beloved) Thinkpads a much desired processor upgrade. This is the work of the user [HOPE] on the enthusiast forum 51nb. The hack exemplifies what happens when that passion for legendary gear hits deep electrical expertise and available manufacturing. This isn’t your regular laptop refurbishment, [HOPE] is building something new.

The end result looks like it could have come out of a Lenovo factory just before Spring Festival. If you look closely at the image at the top of this article, you might notice they even included an improved “Intel Inside” sticker on the palm rest and a model number label at the lower left of the display!

MeetBSD 2014 is approaching

The MeetBSD conference is coming up, and will be held on November 1st and 2nd in San Jose, California
MeetBSD has an “unconference” format, which means there will be both planned talks and community events
All the extra details will be on their site soon
It also has hotels and various other bits of useful information – hopefully with more info on the talks to come
Of course, EuroBSDCon is coming up before then

First experiences with OpenBSD

A new blog post that leads off with “tired of the sluggishness of Windows on my laptop and interested in experimenting with a Unix-like that I haven’t tried before”
The author read the famous “BSD for Linux users” series (that most of us have surely seen) and decided to give BSD a try
He details his different OS and distro history, concluding with how he “eventually became annoyed at the poor quality of Linux userland software”
From there, it talks about how he used the OpenBSD USB image and got a fully-working system
He especially liked the simplicity of OpenBSD’s “hostname.if” system for network configuration
Finally, he gets Xorg working and imports all his usual configuration files – seems to be a happy new user!

NetBSD rump kernels on bare metal (and Kansai OSC report)

When you’re developing a new OS or a very specialized custom solution, working drivers become one of the hardest things to get right
However, NetBSD’s rump kernels – a very unique concept – make this process a lot easier
This blog post talks about the process of starting with just a rump kernel and expanding into an internet-ready system in just a week
Also have a look back at episode 8 for our interview about rump kernels and what exactly they do
While on the topic of NetBSD, there were also a couple of very detailed reports (with lots of pictures!) of the various NetBSD-themed booths at the 2014 Kansai Open Source Conference that we wanted to highlight

OpenSSL and LibreSSL updates

OpenSSL pushed out a few new versions, fixing multiple vulnerabilities (nine to be precise!)
Security concerns include leaking memory, possible denial of service, crashing clients, memory exhaustion, TLS downgrades and more
LibreSSL released a new version to address most of the vulnerabilities, but wasn’t affected by some of them
Whichever version of whatever SSL you use, make sure it’s patched for these issues
DragonFly and OpenBSD are patched as of the time of this recording but, even after a week, FreeBSD (outside of -CURRENT) and NetBSD are not

Interview – Robert Watson – rwatson@freebsd.org

FreeBSD architecture, security research techniques, exploit mitigation

News Roundup

A FreeBSD-based CGit server

If you use git (like a certain host of this show) then you’ve probably considered setting up your own server
This article takes you through the process of setting up a jailed git server, complete with a fancy web frontend
It even shows you how to set up multiple repos with key-based user separation and other cool things
The author of the post is also a listener of the show, thanks for sending it in!

Backup devices for small businesses

In this article, different methods of data storage and backup are compared
After weighing the various options, the author comes to an obvious conclusion: FreeNAS is the answer
He praises FreeNAS and the FreeNAS Mini for their tight integration, rock solid FreeBSD base and the great ZFS featureset that it offers
It also goes over some of the hardware specifics in the FreeNAS Mini

A new Xenocara interview

As a follow up to last week’s OpenSMTPD interview, this Russian blog interviews Matthieu Herrb about Xenocara
If you’re not familiar with Xenocara, it’s OpenBSD’s version of Xorg with some custom patches
In this interview, he discusses how large and complex the upstream X11 development is, how different components are worked on by different people, how they test code (including a new framework) and security auditing
Matthieu is both a developer of upstream Xorg and an OpenBSD developer, so it’s natural for him to do a lot of the maintainership work there

Building a high performance FreeBSD samba server

If you’ve got to PXE boot several hundred Windows boxes to upgrade from XP to 7, what’s the best solution?
FreeBSD, ZFS and Samba obviously!
The master image and related files clock in at over 20GB, and will be accessed at the same time by all of those clients
This article documents that process, highlighting some specific configuration tweaks to maximize performance (including NIC bonding)
It doesn’t even require the newest or best hardware with the right changes, pretty cool

64bit time in OpenBSD

Many operating systems face an upcoming challenge, similar to (but more complicated than) Y2K: Y2038. All of the BSDs and most other operating systems track time by counting the seconds since Jan 1st, 1970. In 2038 this value will reach the maximum value of a signed 32 bit integer.
Simply changing to a 64 bit counter may not be the best solution, because there may still be 32 bit systems in use for embedded applications
Theo will be giving the keynote at EuroBSDCon on the subject, explaining how OpenBSD has implemented the solution
No other BSDs have it yet
ABI incompatibility. Updating to this kernel requires extra work or you won\’t be able to login: install a snapshot instead. Upgrading by source is for the insane only.

AESNI pipelining gets a speed boost

AES-NI is a new processor instruction available on modern Intel and AMD chips that provides hardware acceleration for AES encryption and decryption. This feature is especially useful for encrypted disks, because it removes most of the performance penalty traditionally associated with encryption
The new commit has the instructions pipelined, so there is no latency between the instructions
Uses SSE2 instructions for calculating XTS tweak factor for further increased performance
GELI based disk encryption performance increased by 3x on capable CPUs
Should affect PEFS and other AES backed encryption schemes as well
Full disk encryption should be more or less transparent now

OpenBSD 5.4 Preorders

Every 6 months there is a new OpenBSD version
They include a fun song and nicely-packaged CD set
The proceeds from sale of these products is the primary funding of the OpenBSD project
The official ISOs will be uploaded on November 1st

GCC no longer built by default on FreeBSD -CURRENT

On platforms where clang is the default compiler, don\’t build gcc or libstdc++
GCC is still enabled on PC98, because the PC98 bootloader requires GCC to build
While the base FreeBSD system has been built by clang for a long time, this change also covers the ports tree

Patch to update Xorg and Mesa on FreeBSD

Updates xorg drivers
Expected to be committed in about 2 weeks
Adds option to use devd instead of HAL for X configuration
Updates the MESA stack (9.1.6), libGL, DRI, etc
Enables KMS for AMD/ATI cards
Call for Testing
OpenBSD has recently upgraded to Mesa 9.2 for their stable version of Xorg

News Roundup

NetBSD gets basic support for the cubieboard 1 & 2

Very preliminary support for cubieboard 1 & 2 based on the Allwinner A10 & A20 SoCs
Many drivers are stubs with autoconf glue
Contributed by Matt Thomas

Rayservers ditches Linux for BSD

Used them all, Windows, Mac, OpenBSD, Linux
Needed PF, ZFS, disk encryption, lots of networking features, better security
In Linux, \”The new cgroups based memory management ran out of memory – on a 256 GB RAM system whilst it was not using more than 40.\”
BSD now protects the privacy of their email users

HPN for OpenSSH 6.2

High Performance Networking is an SSH patchset to improve transfer speeds by removing the fixed window size and take better advantage of TCP
Maintained as a patchset separate from OpenSSH
First integrated into FreeBSD base as of 9.0
Updated to support 6.2 (available in the ports tree as security/openssh-portable)
The HPN patch set also includes threaded AES-CTR support to increase performance and take advantage of multiple CPU cores for encryption. In this latest patch, threaded AES-CTR now works in all situations (it failed in some specific situations previously). Expected performance increase is ~50%
NONE cipher is now separate from the main patch set. The NONE cipher allows tools like scp and sftp to switch off the encryption for file transfers (when specifically told to do so) to keep encryption from bottlenecking performance and wasting CPU time

Call for testing: OpenSSH-6.3

Mostly a bugfix release
SFTP now supports resuming partially-downloaded or uploaded transfers
More logging features
Six weeks after the initial email, still no release. des@ is not pleased.

pkgsrc gets signing

pkgsrc is used on NetBSD, DragonflyBSD and other OSes
Comes from an EdgeBSD developer
Uses GPG for signing package files
Currently just a patch on github and in its infancy
Provides a short howto

FreeBSD vs. Linux: 10 points of superiority

New FreeBSD user, ex-Linux user writes about his experience
Mentions consistency, documentation, security, filesystems, updates, jails, community
Really long post, definitely worth a read

[Feedback/Questions]

We received TONS of email. We’ll get to a few of the questions, but a lot of them will be answered in future episodes.
hoopla writes in: “I\’m looking to install PCBSD on my laptop and was wondering if there was support for encryption of the root folder in the installer. For my arch linux install I ended up setting up an encrypted lvm by hand and it was hell but if it\’s built into the installer it\’d make the transition to BSD much simpler.”
Juergen writes in: \”hi guys, I want to listen to the new BSD podcast but I couldn\’t find the RSS feed. Can you publish the feed?\”
Due to the way publishing happens at JupiterBroadcasting, there were no RSS feeds until the first episode was published. The feeds for MP3, OGG, SD and HD Video and Torrent are now in the top right corner of the BSDNow.tv page. The episodes will also be published on iTunes once the show is approved by Apple.
Sam write in with two questions: “I want a few simple python web apps. What is the best \”FreeBSD way\” to deploy this? Nginx + uWSGI? It is surprisingly hard to find a usable nginx.conf that I can throw in a jail and run a python app. Is uWSGI even the right tool?”
“The PCBSD tools are great, but the tool versions that are in the ports tree are always out of date compared to what ships with PC-BSD. Why is this? Same with FreeNAS, why is the Warden more up to date in FreeNAS than PC-BSD.. then there\’s yet a 3rd version in ports?”
Frank writes in with a long question: “My company is a major CA. We run virtualized RHEL 6 virtualized on KVM, about 3000 nodes serving different purposes on about 350 pizza boxes also running RHEL/KVM. We have kind of a sale issue. To have both TLS 1.2 support and ECC ciphers available we have to recompile both OpenSSL and NGINX and a few other system packages. I\’ve built RPM\’s, but there still are issues on a default install, relating to other not to be disclosed core business software choughJava based cachough. However, compiling it all on each machine does work.

Now I\’ve got this working on FreeBSD kvm virtual machines, which both provide better performance (almost 30% less resource usage than the RHEL nodes) and also work with our configuration management stack (puppet + homegrown). It also would allow us to drop a lot of virtual nodes because less BSD boxes can handle the same amount as the CentOS ones. And of course the lack of security issues, less software by default on a fresh install and such.

My team also likes it, has knowledge, supports a migration, and the metrics support it, however management is not happy and does not want to do such a big \”migration\”. (Not knowing that about 100 VM\’s are already FreeBSD and working). Also, they don\’t like that they\’ve got a 10 year contract with Red Hat and have paid for that… But, in the end the cost would go down because of the migration.

Any tips to get support from them?”
+ The first thing that comes to mind is to see what other people have done in the past. There was a presentation at BSDCan 2013 in May of this year on this specific topic: Case study: Switching from Linux to FreeBSD
