openSUSE: much more than Linux distributions (osc16)

Sun, 26 Jun 2016 00:00:00 +0200

The openSUSE project was born to ensure the existence and independence of a free (as in free speech) Linux distribution. But there is something you can take for granted if you create a community of technology enthusiasts - at some point they will start to create cool new things. Thus, openSUSE has become the home of many open source projects like OSEM, Portus, Jangouts, Machinery or zypper-docker. Not to mention tools used to build the distribution that have evolved into generic solutions with a lot of presence outside the openSUSE scope, like the Open Build Service or openQA. This talk will try to provide a good overview of the many cool projects living under the openSUSE umbrella, explaining their goals and current status. about this event: https://c3voc.de

SSSD: More than an LDAP client (osc16)

Sun, 26 Jun 2016 00:00:00 +0200

The SSSD project started as a deamon that allows to resolve users and groups in LDAP, but is gaining more features over time. In this talk, I would like to give an overview of the features SSSD has, with focus on what was introduced into the project in the last couple of years or the features we are working on now. In particular, I would like to show how SSSD allows the administrator to easily enroll a client into an Active Directory domain including access control with Group Policies, the options SSSD has for Smart Card authentication or the possibilities to manage secrets with SSSD. In future, we would like SSSD to also manage the local users, traditionally stored in /etc/passwd, which is another topic the talk would outline, at least to show what we are planning. The talk would also include live demo. No previous knowledge about SSSD is required. The presentation would be aimed at administrators and to some degree also Linux distribution or program developers. about this event: https://c3voc.de

Sun, 26 Jun 2016 00:00:00 +0200

openSUSE recently attended the National School Board Conference in Boston, Mass., with a focus of introducing and challenging school districts, teachers and administrators to implement the use and teaching open source software in schools within the United States. Find out the results of this effort and see what openSUSE can do to increase participating in open-source projects at schools in the United States. about this event: https://c3voc.de

GNOME 3.20 - Five years after 3.0 (osc16)

Sun, 26 Jun 2016 00:00:00 +0200

GNOME 3.20 has just been released on 21st of March. With that release, many visible improvements will be delivered to users around the world. While many people already excitedly use GNOME 3 with the new user experience, some features of the new and elegant desktop like LibreOffice integration or editing photos with non-destructive GEGL operations are not yet wildly known. We also did many things on the plumbing layer such as allowing GNOME to run Wayland. The talk will introduce to some of the design philosophies inherent in GNOME 3 as well as the main changes brought to users and developers. Also, since GNOME 3.20 is another step of a long lasting incrementally improved user experience, the future of GNOME's development will be speculated on. about this event: https://c3voc.de

Introduction to performance analysis on openSUSE using Perf (osc16)

Sat, 25 Jun 2016 00:00:00 +0200

The perf tool was introduced with kernel version 2.6.31 but several major releases later, knowing which of its many features to use when and how to interpret the results is still challenging for many users. In this talk I will present a brief overview of the performance counters provided by modern x86 hardware followed by a discussion of the various monitoring capabilities offered by perf, when to use which and how to begin to interpret the results. This is intended as an introductory talk for those with no significant experience using perf or undertaking performance analysis. An understanding of programming and architecture basics will be helpful. [This talk could be extended to an hour if required, it could also be presented instead as a workshop or as a talk plus an associated workshop] about this event: https://c3voc.de

Orchestrating Docker containers (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

As more and more users are starting to consider Docker in production environments, people have realized that having Docker alone is not enough. Instead, the community is gearing towards orchestration solutions: tools, frameworks and practices that deal with how containers are deployed on production and how administrators can monitor all this without going crazy. In this talk we are going to describe and detail the orchestration solution that we decided to support in SUSE, why we did it and how our users will benefit from it. about this event: https://c3voc.de

openSUSE Maintenance (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

While openSUSE has a rolling release, which is constantly integrating new versions and bugfixes, we also have releases where the main codebase is frozen and we release bugfix and security updates via online updates. This process has been established for a while and is coordinated by the openSUSE Maintenance Team. Also, last year a new release came with new and changed update origins, openSUSE Leap 42.1. This release inherits some parts of its updates from SUSE Linux Enterprise 12, which might be confusing at times. This talk will offer a refresher on the maintenance processes and also some details you as packager needs to observe, also especially in regards to Leap. about this event: https://c3voc.de

Ceph and Storage Management with openATTIC (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

openATTIC is an Open Source Storage Management System, sponsored by it-novum. Over the last five years, it has matured into a flexible and robust framework to address today's storage management requirements. Using openATTIC, one can easily manage storage resources like NFS/CIFS shares as well as iSCSI and FibreChannel targets via a modern web interface. Moreover, openATTIC supports a wide range of file systems including Btrfs and ZFS, as well as automatic data replication using DRBD®, the distributed replicated block device and automatic monitoring of shares and volumes using a built-in Nagios/Icinga instance. With version 2.0 which is currently under development, the openATTIC developers have made some significant changes. In addition to replacing the existing XML-RPC API with a RESTful API, the entire Web UI has been rebuilt from scratch using modern web technologies. In addition to traditional storage, openATTIC 2 will also support managing the Ceph distributed object store and file system. This talk will give an overview about openATTIC, it's current state of development as well as an insight into the collaboration with SUSE on porting openATTIC to the SUSE Linux distribution and the ongoing development of additional Ceph management features. about this event: https://c3voc.de

Infrastructure-as-Code and CI Infrastructure at OpenStack (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

Let's look how another open source project administrates their community infrastructure and have setup their testing of software. I want to give an overview how development, documentation, and system administration at OpenStack follow the same workflow, what kind of infrastructure OpenStack uses for testing the changes and what major design decisions have been done. Also, I like to explain how system administration of the community servers is done.

My Last talk - what's that distribution? (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

I assume this will be the last talk I ever give, because after this every one, every single distribution's community will be out to kill me. Ladies and Gentlemen, bring your hatchets! I have collected quotes, sentences and assumptions that speak for themselves. While I am only showing one sentence each slide, the audience will have to guess the distribution that is meant. Be prepared to discuss: Who is the "Microsoft of open source?" Who thinks they own open source? Who was bought twice, while both buyers don't exist anymore? Who has hired a Gentoo guy as head of package management? Who is still compiling Libre Office and can't open a document therefore? What's that distribution with three, four, five names, constantly changeing? Add your own, this Lightning talk is open source, and a call for your ideas and discussion. about this event: https://c3voc.de

Security and openSUSE (osc16)

Wed, 22 Jun 2016 00:00:00 +0200

SUSE employs a security team which has as main duty keeping SUSE and openSUSE secure. With openSUSE and SUSE Linux Enterprise being close and deriving from each other, taking care of security in openSUSE development is also benefitial for SUSE Linux Enterprise Development. The talk will give an introduction on what the SUSE Security Team does and how it works, especially in light in cooperating with openSUSE. about this event: https://c3voc.de

ceph: a gentle introduction (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

Unlike many storage systems ceph storage is here to stay, this talk will explain how this storage solution is winning friends with its simplicity, stability, scalability and performance. This talk will show the elegance of ceph rather than the dirty details, but you can always ask questions. about this event: https://c3voc.de

OpenDOC: Automating Documentation (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

A suggestion for a new approach to documenation. "Breaking the perception that a rolling release cannot be documented" Forums, mailing lists, wikis, release notes, Git commit comments, QA tools like Open QA and many more: A vast abundance of resources offer indicators for documentation. However the data is neither collected nor structured nor viewed at all, mostly because everybody thinks it's a tedious work. But modern knowledge management tools can collect the data, structure it, add semantic analysis and put it into a format that a community can benefit from - with minimal human input. Imagine a website like Stackoverflow or Reddit, but (open source and company-independent) with automated input, but ranked by interest (views), helpfulness and discussion thread length. The input triggers could become an open project, like Open QA's tests. A "Doc Gardener" could then pick up the most important tasks and move them to openSUSE wiki or Enterprise Documentation, at the same time helping the community and spotting pain points of the community. about this event: https://c3voc.de

Enforcement of a system-wide crypto policy (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

Currently each and every shipped application in distributions enforces its own policy on the allowed cryptographic algorithms/protocols. While for some this is a desirable property, for most non-UI applications and libraries in an operating system it creates an uncertainty on the available security level. The purpose of this talk is to describe the approach we've taken in Fedora to counter the issue, by enforcing system-wide policies, discuss the current outcome, lessons learned, and invite OpenSuse maintainers to participate.

BitTorrent Peer-to-peer controlled by Salt (osc16)

Wed, 22 Jun 2016 00:00:00 +0200

Our task is to distribute software to Windows clients. Our network contains slow links and relay-servers, which must be staged up. Our goals are 1) reduce WAN traffic, 2) allow unlimited size, 3) allow unlimited number of clients in one rollout, and 4) start rollout without delay. Idea :: BitTorrent Peer-to-peer (P2P) reduces WAN traffic because if prefers local content over remote content. Beneficially for the concept, all clients are centrally configured: no peer can be a leach. Clients act as a storage resource for other clients, eliminating the need for relay servers. Realization :: We found that Salt manages a BitTorrent agent nicely with Salt-states. Experience/Result :: We have continuously distributed 2 GB per day to up to 50 Minions for over 2 months. Clients and network are undisturbed, while a Salt-Master on a regular desktop administers 50 Minions effortlessly. We fully meet all of our goals. We observe an increasing and by now high reliability with P2P and Salt (in this order), but glitches still occur in both domains. Live Demo :: How to distribute 500 MB, present at 4 clients, to 8 more clients? During transmission, we will stop the P2P service on some of these 8 clients via salt and then start it again, to simulate clients going temporarily offline. Next Steps :: Making Minions 'more active'. Activating and deactivating the P2P service on demand. about this event: https://c3voc.de

Getting Geeko some cross-compilers (osc16)

Sat, 25 Jun 2016 00:00:00 +0200

openSUSE relies on native compilation today, resorting to QEMU linux-user emulation for non-native build targets. Here's a brief update of where we are with building real cross-compilers, including for non-Linux targets such as microcontrollers, from our SUSE-maintained GCC packages. about this event: https://c3voc.de

Config Files API (osc16)

Sat, 25 Jun 2016 00:00:00 +0200

YaST has been trying to find a solution to work with configuration files in a way that is easy and reusable, while ensuring the consistency of the resulting configuration. The response is Config Files API (CFA), a generic framework to work with configuration files in Ruby. Although currently is only used in the yast2-bootloader module, CFA will become one of the key components of YaST in the near future. Its design and foundation look beyond YaST, making it a useful resource in any environment needing programatic and semantic management of configuration files. The talk will provide an overall overview of CFA's architecture and down to earth examples on how CFA can be used and extended. about this event: https://c3voc.de

Porting openSUSE to MIPS (osc16)

Sat, 25 Jun 2016 00:00:00 +0200

OBS and the real cool stuff (osc16)

Sat, 25 Jun 2016 00:00:00 +0200

OBS (Open Build Service) is an awesome piece of software which is yet unmatched by other available software suites. This talk shows how Kopano approached the change in their build system, and how they integrated fully fledged build requirements into OBS. From adding real custom distributions such as Collax (just using DEB, without bootstrapping at all) to integrating with Atlassian Stash - All this is possible with OBS and much more. How did we make OBS accessible for Windows users (using osc), how did we make sure we can make a sane structure based on build-time requirements for packages and not just include everything for distribution in the end? Where can I use curl requests, and how are they structured. And did you know there are authentication tokens? This talk delivers the answers to these questions. This talk will include a QA session in the end with the chance to give an answer on many (unfortunately also undocumented) features. about this event: https://c3voc.de

Sat, 25 Jun 2016 00:00:00 +0200

The first openSUSE.Asia was awesome in Beijing, China, and this time we also made it great in Taipei , Taiwan. We designed some event made it different, and connected with local community to do more sharing and promotion for openSUSE. Just like last year said , we would like to continue this event in the future, so we will take this opportunity to introduce 2nd summit what it different, and what did we miss. This talk is quite flexible, we invite you to share your local openSUSE community, openSUSE events and openSUSE promotion in brainstorm. Or give your suggestion or advice about openSUSE promotion. Overall, anything about openSUSE promotion is welcome. about this event: https://c3voc.de

Distribute or Die - Arguing against Additional Repositories. (osc16)

Sat, 25 Jun 2016 00:00:00 +0200

openSUSE has a wonderful platform with OBS, and tools like software.opensuse.org and 1-Click installs make it very easy for users to get additional software on their machines. This talk will discuss how this is quite often a very bad thing, leading to problems for users as well as extra work for maintainers in both the short and long term. It will discuss the benefits of putting software packages in both of openSUSE's distributions (Leap & Tumbleweed) and propose concrete steps which users and responsible package maintainers can take to ensure everything is put together and working as smoothly as possible. Finally, the session will accept the reality that putting absolutely everything in a distribution is infeasible and discuss possible criteria and guidelines for sensibly defined, maintainable additional repositories that avoid the issues raised earlier in the session. about this event: https://c3voc.de

Testing complex software in CI (osc16)

Fri, 24 Jun 2016 00:00:00 +0200

This talk will show stories from the trenches of developing tests for SSSD and Samba. How we developed complete integration tests that exercise all the capabilities of our software and run in environments without a real network access, without requiring root or sudo or touching the important OS interfaces. The authors of this talk work on SSSD, Samba and libssh - software that communicates over the network, often requires root access and communicates through OS interfaces. In this talk, we will show how we developed complete integration tests that exercise all the capabilities of our software and run in environments without a real network access, without requiring root or sudo or touching the important OS interfaces. In addition, our goal was that the tests must be easy to develop and must run both locally on developer's machine as well as inside popular CI engines of today, like Travis or Semaphore. To meet these goals, we had to leverage existing testing tools, but also build new ones such as pam_wrapper or libpamtest to be able to test OS-level PAM authentication and authorization. This talk will be useful for developers who write tests for software that is normally not easy to test -- attending the talk will show you how to test complex software systems in isolation. about this event: https://c3voc.de

Hacking Salt for fun and profit (osc16)

Wed, 22 Jun 2016 00:00:00 +0200

After the SUSE Manager team had chosen Salt as the future engine behind SUSE Manager, Joachim "Joe" Werner, the product manager for SUSE Manager, spent some time to learn the project hands-on. This is a very personal report about that experience, from extending Salt with code to manage WIFI-controlled LED lamps for a demo at the SUSECon conference to first experiments with writing a Salt module for Snapper. This talk is for you if you don't just want to know about using Salt for configuration management, but are more interested in contributing to it or hacking it for your own needs. Basic Python skills recommended to make sense of the example code. ;-) about this event: https://c3voc.de

What do we mean, biblical? 40 years of darkness, earthquakes, volcanos, human sacrifice, mass hysteria, dogs and cats living together... and on that note, did you know that openQA is used by both openSUSE and Fedora? What is so awesome about this tool that traditional distribution enemies are now working together? openQA is an automated testing tool, capable of full system, console, and graphical application testing. This session will give an introduction to openQA's capabilities, share how it is used by openSUSE for the testing of Tumbleweed and Leap, and suggest ideas to attendees as how it could be used for testing their software, operating systems, or virtual machine images. about this event: https://c3voc.de

A Guided Tour of Machinery (osc16)

Fri, 24 Jun 2016 00:00:00 +0200

As a Linux system administrator you are constantly working on tasks like: - Cloning a system from an existing one - Migrating a system to new hardware, a virtual environment or a different distribution - Debugging a broken system - Upgrading a system - Integrating your systems into a configuration management tool Determining and comparing the state of a system in order to work on these tasks is not a trivial thing. You have to know about services, packages, configuration files, etc. This proves to be even harder if one or more of your systems differ in version and/or distribution. You can use Machinery to inspect your Linux systems and use the generated descriptions to be interpreted in an off-line fashion, giving you the ability to compare a system at different points in time or against another system. Peace of mind will be the result of knowing that you can ensure the resulting state of your system and many other types of analysis based on your system descriptions. In this guided tour you will explore the basics of Machinery and see some examples in the wild. All from the safety of your seat. The focus will be on openSUSE systems but stay open to the use of any other distributions. Should you have any questions about Machinery your guide will be there for you at all times. about this event: https://c3voc.de

Managing VMware infrastructure using salt-cloud (osc16)

Wed, 22 Jun 2016 00:00:00 +0200

Want to learn how to deploy VM's on the fly in your VMware infrastructure using the orchestration power of salt-cloud? Attendees will walk away from this workshop/presentation with the tools, skills and knowledge to deploy and manage VM’s in their VMware environment in a reproducible, maintainable and a manageable way using salt and salt-cloud. We will be explaining how VM's can be created and destroyed across multiple vCenters, how they can be easily queried and how various tasks can be performed on vCenters. We will also show you how you can perform simple tasks such as creating/removing snapshots of VM’s, starting/stopping/suspending/resuming VM's, querying VM's for information etc using salt-cloud! This workshop/presentation is a great use case on how Clemson University has used SaltStack Software (salt, salt-cloud) to automate it's VMware environment and the day to day routine tasks performed by the VMware administrators and made it simpler for people with no prior VMware knowledge to easily deploy and manage the VM's in their environment.

Let openQA test you own stuff (osc16)

Fri, 24 Jun 2016 00:00:00 +0200

OpenQA is openSUSE's powerful installation testing environment. It normally tests whole ISO images that need to be mastered first it is not very straightforward to check single packages within the development process of new features or bug fixes. I'll show you how we managed to test our stuff as early as possible without mastering whole ISOs and how we enabled our developers to easily adapt existing openQA tests to changes in YaST's behaviour and user interface to be able to deliver updated openQA tests along with updated YaST versions. about this event: https://c3voc.de

uEFI grub2 on Raspberry Pi (osc16)

Fri, 24 Jun 2016 00:00:00 +0200

Booting is hard. Booting in the ARM world is even harder. State of the art are a dozen different boot loaders that may or may not deserve that name. Each gets configured differently and each has its own pros and cons. As a distribution this is a nightmare. Configuring each and every one of them complicates code that really should be very simple. To solve the problem, we can just add another layer of abstraction (grub2) on top of another layer of abstraction (uEFI) on top of another layer of abstraction (u-boot). Follow me on a journey on how all those layers can make life easier for the distribution and how much fun uEFI really is. After this talk, you will know how ARM systems boot, what uEFI really means, how uEFI binaries interact with firmware and how we are going to move to uEFI based boot on openSUSE for ARM. about this event: https://c3voc.de

An Embedded USB Cloud Storage Gateway with Tumbleweed (osc16)

Fri, 24 Jun 2016 00:00:00 +0200

Scale-out block storage offerings, such as Ceph RADOS Block Devices, offer a number of desirable features including fault tolerance, thin-provisioning, online resize and snapshots. Exposing such storage for access via an embedded USB storage gadget can solve a number of factors limiting adoption, namely: - Interoperability + Cloud storage can now be consumed by almost any system with a USB port - Ease of use + Configure once, then plug and play anywhere - Security + Encryption can be performed on the USB device itself, reducing reliance on cloud storage providers This presentation will introduce and demonstrate a USB cloud storage gateway prototype developed during SUSE Hack Week, running on an ARM board with openSUSE Tumbleweed. about this event: https://c3voc.de

SaltStack is more than just configuration management (osc16)

Wed, 22 Jun 2016 00:00:00 +0200

In this presentation, Thomas Hatch, SaltStack CTO and technical founder, will provide a quick overview of the evolution of IT automation and describe his motivations for creating the Salt open source project. Thomas will also define how SaltStack is different than other systems management tools and is the first to deliver a single platform for remote execution, configuration management, cloud control and event-driven automation. Specifically Thomas will provide a glimpse at the future of event-driven automation and how it will change the way IT operations and DevOps teams deploy, control and secure data center infrastructure and application components. Thomas will be joined on stage by Joe Werner, SUSE product management, and Dave Boucha, SaltStack engineering. Joe will highlight how the newest version of SUSE Manager leverages Salt and why Salt was the SUSE automation platform of choice. While Dave will provide a demonstration of SaltStack event-driven automation. about this event: https://c3voc.de

The state of ARM - a 64bit view of what does/doesn't work (osc16)

Fri, 24 Jun 2016 00:00:00 +0200

The AArch64 port is now in pretty good shape with most things ported and built. However we know that there is plenty of software that is not optimised and some may not actually work at all. Please come along and moan about anything you have found which doesn't work as well on AArch64 as it does on x86. We (Linaro, ARM and openSUSE) want your feedback on where to direct effort next. This talk will cover the current status of the port with both and upstream and openSUSE specific view, and crucially hardware availability. Only a few things are completely missing, but we know that a lot of software is using the basic 'fallback support' where other architectures have specific optimisations. Some stuff is probably building, but not actually working right. We are keen to fix things that are actively getting in the way of using AArch64 in real systems, but to do that we need feedback from users on what to look at next as we move from mostly enablement to mostly optimisation. GCC, OpenJDK, & LLVM are known to be in good shape, but there is a pile of other stuff that probably isn't. It's very hard to test 'all the software in the world', so please tell us about stuff you've noticed not working well, or incredibly slowly, or that you suspect might be a problem and need work. about this event: https://c3voc.de

AppArmor Crash Course (osc16)

Fri, 24 Jun 2016 00:00:00 +0200

AppArmor is an effective and easy-to-use Linux application security system. AppArmor proactively protects the operating system and applications from external or internal threats, even zero-day attacks, by enforcing good behavior and preventing even unknown application flaws from being exploited. AppArmor security policies, called profiles, completely define what system resources individual applications can access, and with what privileges. A number of default profiles are included with AppArmor, and using a combination of advanced static analysis and learning-based tools, AppArmor profiles for even very complex applications can be deployed successfully in a matter of hours.

This talk gives an introduction to AppArmor. I'll show the AppArmor tools to create and update profiles and also explain the profile syntax so that you can understand and manually edit profiles. I'll also show some advanced usage - securing a typical webserver, setting up read-only root access to do backups and how to (ab)use AppArmor for debugging. about this event: https://c3voc.de

We'll look at the motivation behind KDE Neon, the involved technologies and services, and it's place within the KDE community as well as the ecosystem at large. about this event: https://c3voc.de

Deliver personalization, remain legally compliant, AND respect privacy with open source! (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

What good is a website when you don’t have the faintest idea who’s visiting it, where they come from, where they go, and what they want? And how can you find out all that whilst respecting your users' privacy and still complying with myriad, pesky national privacy laws and regulations? My answer is simple: go open source! Go Piwik! Piwik is a great, open source web statistics application, similar to Google Analytics, that integrates very well with numerous platforms including Drupal. This has been a hot topic for a few years and the talk has gone through a couple of iterations for some major conferences (like DrupalCon 2013 in Prague and openSUSE Conference 2012 in Thessaloniki and Observe Hack Make in 2013). It is frequently updated to reflect the current legal and regulatory situation, which is still changing and developing (almost daily, it seems). [takeaways] In this talk, the audience will learn: The current state-of-play regarding privacy laws, especially in Europe. How well Drupal and Piwik compliment each other. How to deliver “fair-play” personalization. about this event: https://c3voc.de

Reproducible builds everywhere and beyond (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

The presentation will describe how the Debian reproducible builds team made 85% of the Debian archive reproducible, what steps are left to reach 100% and what steps are needed beyond reproducible builds, so that every user can easily and meaningful benefit from them. While the presentation will be largely about the Debian work on the area, it will also portray many other projects collaborative work on reproducible builds, as our goal is to make reproducible builds the norm for free software: "It's not free software if it's not reproducible." https://reproducible-builds.org about this event: https://c3voc.de

openSUSE and SUSE Linux Enterprise (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

Content: Leap and the SUSE Linux Enterprise products share a lot of things in common. At the same time, they vary in a lot of aspects. Some of them are caused by fundamental differences in the philosophy and the basic properties of the projects. With the upcoming SP2 of CODE 12 of SUSE Linux Enterprise it's time to look at those differences and similarities, as the codebases will be getting closer again. about this event: https://c3voc.de

reproducible builds and openSUSE (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

Linux distributions like openSUSE ship binaries and because it is all free/open source software, users also can get the source code, but often it is not possible to verify that the shipped binary was really produced from this source (e.g. without added backdoors) This talk intends to inform about the https://reproducible-builds.org/ initiative in general and openSUSE's progress in that direction in particular. about this event: https://c3voc.de

Introduction to the Linux Block I/O Layer (osc16)

Wed, 22 Jun 2016 00:00:00 +0200

In the last years the kernel's block I/O layer has been subject to quite some substantial changes. Ever increasing IOPS rates delivered by Flash based storage and high end SAN infrastructures demanded a refactoring of the I/O layer towards a lockless, multicore utilizing design. This talk will give a short introduction to both, the classic block layer and the so called multi queue block layer. about this event: https://c3voc.de

Static Code Analysis for All Languages - coala! (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

coala provides a common command-line interface for linting and fixing all your code, regardless of the programming languages you use. It supports way over 30 languages in addition to language independent routines. So, instead of building new analysis tools from scratch you can now build logic only and let coala deal with the user. This talk features a short introduction into the thoughts behind coala, it's ability to speed up research as well as increase productivity. about this event: https://c3voc.de

MySQL Firewall (osc16)

Thu, 23 Jun 2016 00:00:00 +0200

MySQL Firewall is an application level firewall filter that intercepts incoming queries and validates them against a database of normalized "safe" queries. As an integral part of the server it takes advantage of the parsing and normalization that is done anyway so it has minimal impact on normal operations. The firewall has multiple modes. In learning mode it collects the incoming query normalization in a scratchpad that can be persisted to disk. In alert mode it will just alert the DBA for an unknown query but still let it pass. And in protecting mode it will reject all unknown queries. The firewall can be used to limit SQL injection or as a complement to the privilege system to support only particular front end applications. We will go through all of the stages of installing, training and arming the MySQL firewall with understandable examples. about this event: https://c3voc.de

Bridging openSUSE and SLE gap (osc16)

Wed, 22 Jun 2016 00:00:00 +0200

Starting with (upcoming) Leap 42.2 and SLE 12 SP2, a lot of cooperation has been done to bridge gaps between the two distributions. We'll talk of one specific example, GNOME desktop, where openSUSE and SLE teams worked together on improving our common work and how it helped both teams. This is still a work in progress at the time of this writing, we'll be sharing what we achieved, how we did it, what failed (if it did) and how we can improve. about this event: https://c3voc.de

openSUSE in Numbers 2016 (osc16)

Wed, 22 Jun 2016 00:00:00 +0200

During 2013 we provided some data about numbers of users and downloads of openSUSE. Now in 2016 we have a different scenario: Tumbleweed is the a new kind of rolling distribution that base the quality on automatic tests (openQA) and a better development process. Leap is also a new kind of stable distribution, a chimeric approach that mix the head of a enterprise product (SLE) and the heard of Factory. Those changes are so deep that 2016 deserve an update of the analysis done in 2013 about openSUSE users and downloads! about this event: https://c3voc.de
