Are you new to the open source community? Or you are not even sure if it could be something for you? I will tell you how I started as an open source contributor and what from my experience makes open source and openSUSE such as interesting option.

I will provide some tips to give your first steps in the open source world. In this line, I will speak about mentoring programs, focusing on GSoC (Google Summer of Code), in which openSUSE participates and in which I personally have participated as a student, mentor and organisation admin. I will explain what this program is about and why it is important for openSUSE. I will show projects from last years and for everybody interested in participating I will cover who can apply and how to do so. Last but not least, I'll present examples of ideal projects to start contributing to, both inside and outside openSUSE.

Working (in the field of graphic design) with open source applications is sometimes still a scary thing. This is because the use of proprietary products on the market is quite dominant. This often makes non mainstream applications such as Inkscape, Gimp, Krita, Synfig, etc. which incidentally is open source application underestimated. In fact, these applications are highly qualified and powerful to meet the needs of graphic design both general and specific.
In this session, I will describe my experiences during using these applications to create designs in openSUSE. In addition, I will also tell you about the design community in Indonesia that has been fully using open source applications as the main application to create graphic design work. This community is named Gimpscape ID.
Finally, I will describe what I have done to contribute to an open source project through this graphic design. Hopefully after this session, users of open source design applications are more confident and willing to contribute as well.

What is necessary for the next input method framework

Fuminobu TAKEYAMA

IB201

08/11 10:30 - 11:00

English

Skilled / 中階

Input method framework is a software that has been used to input complex characters (e.g., Chinese characters, Hiragana, Hangul). Strictly speaking, the role of input method framework is bridging desktop applications and input method engines, which translate typed keys into complex characters. During this two decades, several input method frameworks including Kinput2, SCIM, UIM, Gcin, Fcitx, and IBus have been developed.

The situation surrounding text input method is changing. Firstly, new approaches such as software keyboard for touch screen and speech to text input are available on platforms other than Linux desktop.

Another change is the integration of input method into desktop application platforms. For example, IBus is now a part of GNOME desktop environment; Not only GNOME, Qt also include IBus support. Furthermore, Flatpack also uses a subset of IBus D-Bus interface for applications in Flatpack sandbox to communicate with an input method running on its host desktop.

Some people might think IBus is the defacto standard input method framework. However, quite many people prefer Fcitx or else due to the design issues of IBus. The latter people might think they are losing their freedom to select input method framework.

Now the speaker thinks that it is time to discuss the variety of input method frameworks is really necessary for the future Linux desktop environment. An input method framework itself does not provide much experience for users because its primary role is usually invisible to users. Thereby, how about bringing the war of input method framework and using our effort to improve input method engine, implementing the new approaches mentioned above, and supporting newer application platforms like Wayland?

In this talk, we would like to discuss what is necessary for the future input method framework by reviewing the design issues of IBus. The topics will be as the followings:

  • Thin and high-level protocol with libraries avoiding code duplication
  • The separation of responsibility between IBus daemon and plugins
  • Importance of opened community

Note that the speaker is neither a developer of IBus nor GNOME. The attendees from GNOME community are welcome to improve this discussion.

openSUSE has released a new distribution Leap 15 on openSUSE Conference 2018. openSUSE Leap 15 shares a common core with SUSE Linux Enterprise (SLE) 15 sources and has thousands of community packages on top to meet the needs of professional and semi-professional users and their workloads.
For the first time, SUSE will support migration from Leap to SLE, which gives system integrator developing on Leap the possibility of moving to an enterprise version for certifications, mass deployments and/or extended Long Term Support. openSUSE Leap 15 brings plenty of community packages built on top of a core from SUSE Linux Enterprise (SLE) 15 sources, which is the first time the two major releases were built from the beginning in parallel.
As a tester of this new feature, I wish I could communicate with you about this feature, and share with you how to perform the migration from Leap to SLE on openSUSE.Asia Summit.

Aksara Nusantara is a variety of script or writing that is used in the archipelago to specifically write a particular regional language. Although the Arabic alphabet and Latin alphabet are also often used to write regional languages, the term Aksara Nusantara is often associated with the letters of inculturation of Indian culture. Various kinds of writing media and stationery are used to write the script of the archipelago. Writing media for inscriptions include stone, wood, animal horns, gold plates, silver plates, copper temples, and bronze plates; writing made with chiseled stationery. Writing media for manuscripts include palm leaves, nipah leaf, coconut leaf, bamboo blades, bark, local paper, imported paper, and fabrics; writing made with stationery in the form of a knife or a pen and ink.
Aksara Nusantara is a unicode script located on the cluster of islands in Indonesia, Java, sunda, rejang, bugis, balinese which is the legacy of tribal characters in indonesia.
here I present how to write with Java input method, bali input methodist, rejang input metode, bugis input methode, batak input mothode at operating system Open Suse.
Unicode archipelago is a project developed by indonesian developers who are now in suspended animation, for that in this event hopefully can revive the archipelago unicode, so as can be an inheritance and can be used in education.

The EFI boot services variable can only be accessed by signed EFI execution when secure boot is enabled by user. We can use the mechanism to store a random number in boot services variable as a root key. The root key can be sused to encrypt and authenticate other keys in key retention service in Linux kernel. It can be a new key type.

This talk introduces the EFI key:

  • EFI key:
  • A new master key type to key retention service.
  • It can be a new option beyond trusted key(TPM) and user key.
  • ERK (EFI Root Key)
  • EFI stub generates a random key and stores in EFI boot services variable.
  • The ERK is secure when secure boot enabled.
  • User must aware and enable secure boot by themself if they want.
  • ERK can be a secret to encrypt a random number for generate a EFI key
  • The EFI key can be used by hibernation encryption/authentication.
  • The EFI key can be a master key to generate a encrypted key for EVM.
  • Rescue mechanism for ERK.

Recently, public clouds are getting to a majority of
infrastructures. For example, using containers, Docker, Kubernetes,
Web applications, etc. Of course, public clouds are very convenient
because they are very easy to use and cheap comparing to using
physical machines. However, it's sometimes a bit boring for some
people who want to know/manage the whole of the things such as physical network,
storage, machines, etc. And also, an experience of building a tiny
cloud with physical machines could be a very good opportunity to
understand computer technologies. Moreover, it's fun for such people
like me.

I had built a my own tiny private cloud with openSUSE and OpenStack on
my own physical machines. And I'm now using it for some of purposes
such as evaluating new Linux distributions, containers, Kubernetes,
etc. I had allocated the budget around only 50k JPY (500USD) for
building it. It's quite a cheap to build a cloud system, actually.
However, it can be done with open source software and some tricks.

In this talk, attendees will get to know about the tiny private
cloud
how to build, issues/challenges, benefit and the potential
capabilities of openSUSE.

openSUSE project, a community program sponsored by SUSE in order to promoting the use of Linux everywhere. This program aims to provides free, easy access to the world's most usable Linux distribution (openSUSE).

openSUSE has been a community-driven project that, despite sponsorship from SUSE, is relatively independent. About two years ago, openSUSE decided to move the base of openSUSE Leap to SUSE Linux Enterprise (SLE), which SLE is a tightly controlled enterprise ship that runs on mission critical systems. The fact is that moving to SLE source code would solve many problems for both SLE and openSUSE via creating a symbiotic relationship in which they can pull the content from each other.

At the end, openSUSE project restructured its distributions and created two distributions: Leap and Tumbleweed.

Tumbleweed, the fully-tested rolling release, became upstream for SLE; whereas Leap is based on SLE and inching itself towards full compatibility with SLE.

I came in to Jogja, March 2009 for Bachelor Degree of Computer Engineering at UIN Sunan Kalijaga and became GNU/Linux user 6 month later since release of Ubuntu 9.10 Karmic Koala.

After 10.04 Release, I am only use GNU/Linux as my operating system on my study, although not many course use GNU/Linux on procces. Latter, I joined GNU/Linux Study Club on my campus, and start learn deeper on GNU/Linux.

Jogja is known as a center of education (City of Students) because almost 20% of its productive population is students. The city is colored by the various background of students that came from various regions in Indonesia. Jogja has private and public/state universities. Jogja have more than 16 universities which have computer related majors. Each campus have similar GNU/Linux Study club. And each month all GNU/Linux study club held regular meeting. Each meeting will talk about GNU/Linux technical or non technical related and held on different location.

From this background, education about GNU/Linux on University become common things. Students start using GNU/Linux base what their need for their study. Many campus often have GNU/Linux Repository, event ther GNU/Linux derivative distribution. Each campus have different fan of distribution too. I join this community until I graduated from my Campus at 2014.

This habit they keep up to the next office. Why? Because now, Jogja move from city of education to city of startup. Because more than 10 big startup create Developer Office on Jogja. And many new startup born everyday.

2018, GNU/Linux community in Jogja did not have bigger fans like ten years ago. But every startup still using GNU/Linux for their development and service what their made, even using all open source tools in development tools.

In this talk, I will present what keys point to make GNU/Linux became common things on Jogja. How it feasible to implement on other city or other country?

A brief introduction to Self Encryption Disk (SED), a hardware based full disk encryption (FDE), which is implemented by hard disk vendors confining to the OPAL storage specification developed by the Trusted Computing Group (TCG).

The SED is not rare or expensive, in contrast, it is relatively easy to find on the market of Solid State Drive (SSD) and is also inexpensive. The feature comes with almost no extra cost (money for real), so why not jump on the boat of encrypting your data through most fancy technology. The talk will let you know about how to identify it.

Second, since it is about Security, the talk will cover the security concerns, and also comparison with Software based encryption on Linux (LUKS).

Third, the majority of the talk is to give you an idea how to set it up in openSUSE, centered around the tool sedutil and will provide you the information of how to use it to accomplish most common tasks (80/20).

Last, it has always been tricky to boot from encrypted device, as we are not only facing trypical chicken-and-egg situation but also different firmware could impose different constraints. We will talk about the solution provided by SED/OPAL spec and also how to use tools in openSUSE to craft that.

LibreOffice is a feature-rich, open-sourced office productive suite and is one of the critical parts of Linux desktop like openSUSE.

Consumer products, like LibreOffice, have to keep continuous evolve to catch end-users' desire than server-side software which is preferred to be more stable than features added. Thus, LibreOffice takes time-based release policy of performing major release with functional additions every six months.

Sometimes you may want to use newer LibreOffice (includes daily build or beta/RC testing build) than pre-packaged version shipped with openSUSE Leap 15 (Leap 15 provides latest "Fresh" LibreOffice 6.0 at the moment (June), but 6.1 will be released August). Of course, you can use TDF build RPM package instead of openSUSE package, but you can do this quickly with modern packaging systems, like Flatpak, AppImage or Snap. Additionally, you can also use several versions parallelly with them.

In this talk, I would like to introduce these ways and pros/cons of the packaging systems on openSUSE Leap 15.

XDP: Unleash The Power of Network Card

08/12 10:00 - 10:30

Mandarin

Skilled / 中階

In the recent years, eBPF is extended across several other fields besides networking in Linux kernel, such as tracing, security, and error injection, and eXpress Data Path (XDP) leads the attention back to networking. Previously, eBPF is used in the generic network stack, and XDP goes further to integrate eBPF into the network drivers. With XDP, it's possible to dynamically inspect the packets right after harvesting them from the network cards. This is especially useful when dealing with the DDoS attack because the packets from the attackers are useless to the whole system, and it's better to drop them as early as possible to save the processing power. Furthermore, the newly merged AF_XDP patch set allows the user to do the zero-copy access to the packets, and this could bring more performance improvement to the userspace program. In this talk, I'll introduce the concept of XDP, the related mechanisms, and the recent updates in Linux upstream.

Nextcloud is a suite of client-server software for creating and using file hosting services. It is functionally similar to Dropbox, although Nextcloud is free and open-source, allowing anyone to install and operate it on a private server.
In contrast to proprietary services like Dropbox, the open architecture allows adding functionality to the server in form of applications and enables users to have full control of their data.
The original ownCloud developer Frank Karlitschek forked ownCloud and created Nextcloud, which continues to be actively developed by Karlitschek and other members of the original ownCloud team.

in the case of this time, I use openSUSE Leap 15.0 to build nextcloud on it, and I will explain briefly how I can build it and installing nextcloud steps above openSUSE Leap 15.0, which turns out to build nextcloud on your own computer is not too difficult, easy even for beginners though.

so we can build their own cloud file hosting, and that too is free to obtain and is an open source

This talk explains HA cluster used by DRBD.
DRBD is block device replication software developed by LINBIT and licensed by GPLv3.
HA cluster is usually an expensive fee for device and controller software.
DRBD can make HA cluster low cost because it is opensource and can use general devices.

Volumes can become the single point of failure. but DRBD can cover it.
and we can use it by manage controllers like drbdmanage or LINSTOR.
LINSTOR has not been yet supported in openSUSE. but, LINBIT quitted development of drbdmanage. and announced developing LINSTOR.
so I explain LINSTOR to provision HA cluster. I wish openSUSE will support LINSTOR. and I think basic philosophy is same.

HA cluster used by DRBD is more usable. DRBD can use with pacemaker and Corosync, with kubernetes. and more. this talk introduces them.
pacemaker and Corosync can manage clusters. pacemaker and Corosync change active node when detecting a failure.
DRBD support kubernetes by Kubernetes Flex Volume plugin.

I remark easy step to setup HA cluster with DRBD. so attendee can learn how to setup HA cluster with easy way and HA cluster background philosophy.

In deploying the server, especially in large quantities, it takes a long time, because the deployment must be done on each server one by one, deployment must also be done in detail so that each server is identical to each other in a group.
If this is done then there is the possibility of one or more of the servers not being identical to the other servers in a group.
So we need a tool to simplify the work, and then we use Ansible to do more deployment in the future. What is Ansible? Ansible is an open-source IT automation engine which can remove drudgery from your work life, and will also dramatically improve the scalability, consistency, and reliability of your IT environment.
We use ansible to deploy web servers, database servers with galera clusters, and session storage servers with master-slave mode. With the use of this tool can reduce the time required in deployment servers, and unidentical server in a group can be avoided

People come and go, but there always someone who willing to maintain and continue the breath of this community. So we have to maintain the good spirit to keep us alive and fun :-)

In the earlier year we always do a monthly or bi-monthly offline meeting, at that time the internet connection still not massive like it is right now. It was important to meet in person to maintain the cohesiveness of the community. While it was good, but that offline meeting only effective in certain area mainly in Jakarta metropolitan area. Right now, the communication means using internet connection, like website, facebook and telegram are more effective.
Off course we still do offline meeting/class but not as many as the earlier year.

As of May 2018, our facebook group have around 4200 member and around 1100 member are active user. Telegram group member are around 370 as of May 2018. Our web site https://opensuse.id is accessed around 51 hits per day.

This is about openSUSE community progress in our country and examining it in the last 3 years, we're on the right track.

The LibreOffice project is an aimed at multilingualism, as stated in The Document Foundation's"Our Values"of"Our Next Decade Manifesto" that anyone can translate so that everyone can use it in their mother tongue.
However, LibreOffice developers are mostly in Europe, and in order to use them conveniently in other languages, those who understand those languages ​​need to solve the problem. LibreOffice 's CJK and problems unique to the Japanese environment are various such as vertical writing, external characters, phonetic, currency and date notation.
Sometimes CJK regression bugs occur in the LibreOffice project. It is important to strengthen user's feedback loop approach. However, I would like to find regression bugs by testing.
In last year's talk, I organized mainly examples of concrete CJK bugs. In this year's talk, As the first, I will analyze the bug database and introduce the trend. Secondly, I will organize major CJK bug cases. Thirdly, I will discuss how to test CJK functionality to find bugs before release.

This will not be a ceph or openATTIC focus talk, even we use it as the example of showing how everything work together. Instead we will look into openATTIC to see how each project work with each other. Mainly focus on Grafana and Prometheus, they are not only very useful for ceph and openATTIC but also equally powerful for monitoring your clusters, vm or cloud / container status.

Both Grafana and Prometheus are very easy to extend, which allow user or administrator to build the dashboard which fit their own need. Even the presentation example will be base on ceph / storage. Participants can use the same idea to monitor any system status they wanted after understand how they work.

For establishing a digital world, the first and foremost requirement is the availability of resources. We used to suffer from electricity blackout for 16 hours per day one year ago. In such a situation, we cannot expect to digitize the area. Now, the situation is not the same. Slowly, the internet facility is expanding in major cities.
Students in college are provided with the knowledge of the open source nowadays. The youths are now becoming aware of the advantages of open source. There are several small opensource communities in Nepal. As an effort to help people familiarize with opensource and to fit the computing behaviour of Nepalese, they have also developed a Linux distro ie. chitwanix. OpenStreet map was widely used for the rescue during the massive earthquake in Nepal. Open Learning Exchange (OLE) Nepal and the One Laptop Per Child (OLPC) are other few initiatives in large scale to digitize Nepal.
Thus, it is our responsibility to spread the knowledge of open source in developing countries like Nepal and it takes time.

This proposal is a continuation of my previous topic on last summit "Flatpak & AppImage Usage on openSUSE. Which One Suitable for openSUSE Users?" (https://events.opensuse.org/conference/summitasia17/program/proposal/1502) that i'm rely on Flatpak on openSUSE Leap since 42.x until 15.0.

Using Flatpak on openSUSE is such a great way that people can use latest application through Flatpak on stable system with openSUSE Leap. Sometimes, people also can try nightly build apps with Flatpak without dependencies hell or break the system and install the same apps with multiple versions. Flatpak (formerly xdg-app) is a software utility for software deployment, package management, and application virtualization for Linux desktop computers. It provides a sandbox environment in which users can run applications in isolation from the rest of the system. Applications using Flatpak need permission from the user to control hardware devices or access the user's files.

On this proposal, I will tell my experience that i am encounter in daily use on last two years on using Flatpak with openSUSE Leap. The audience are Linux user, begineer or advanced. Attendees can expect a how Flatpak use on openSUSE Leap in a great way. This proposal will help users to know how to install with software packages without being confused with dependencies.

During my daily works, I need to create a python package with C language. it is a challenge to finish this in a short time, I read some guide, met some troubles, try my best to fix it and finally have got some tips. if you know how to program in C. such extension modules can do two things that can't be done directly in Python: they can implement new built-in object types, and they can call C library functions and system calls. To support extensions, the Python API (Application Programmers Interface) defines a set of functions, macros, and variables that provide access to most aspects of the Python run-time system. The Python API is incorporated in a C source file by including the header"Python.h". The compilation of an extension module depends on its intended use as well as on your system setup; details are given in the talk. I hope to share it with other people in our community. Thanks!

Portus is an open source authorization service and user interface for the next generation Docker Registry.

Secure:

Implements the new authorization scheme defined by the latest version of the Docker registry. It allows for fine grained control over all of your images. You decide which users and teams are allowed to push or pull images.
Map your company organization inside of Portus, define as many teams as you want and add and remove users from them.

Easily manage users with teams:

Teams have three different types of users to allow full granularity:

  • Viewers: can only pull images.
  • Contributors: can push and pull images.
  • Owners: like contrinutors, but can also add and remove users from the team

Portus provides an intuitive overview of the contents of your private registry. It also features a search capability to find images even faster.

Search:
User privileges are constantly taken into account, even when browsing the contents of the repository or when performing searches.

The Docker Registry on the market is very varied. Do you still have a headache to choose?
Can try Portus, this is a OpenSource tool, but also provides beautiful UI operation
The heart is better to learn immediately

Opensource for better India

India spent around $7.8 billion in IT Sectors in 2017 and the expenditure is expected to reach $8.5 billion in 2018, this is a huge amount. In a country like India, where people living below the poverty lines is more than 22% of the countries 1.3 billion population, money is a scarce resource.

A great portion of this money could be saved by using open source alternatives to proprietary softwares that do the same work at almost no extra cost, and be used elsewhere for better causes.

Government of India has introduced various goals and schemes to develop and bring up the computer literacy to everyone in the country, digital India initiative is one such. OpenForge is an open platform that is aimed at organizing policies aimed at open-source by the Govt. of India.

On 8th November 2016, the government of India announced the demonetisation of all 500 and 1000 rupee bank notes. The whole nation had to suffer in this duration of the cash shortage. The people to suffer most were the ones who had little to no access and knowledge to digital technologies, elderly, low income and less educated were affected the worst. There were even reported deaths due to this.

One of the major barriers in introducing technology to these people is the language. India has more than 880 languages and dialects spoken across the nation. English is still poorly understood, and this is a huge challenge. It is not possible for a single organisation to support most of those languages in the translations. This is where opensource community and contributors come in, without help from the localization communities, significant amount of translations for the utility apps for at least the official languages wouldn't be possible.

Unlike other Linux distros, what people like about openSUSE is its stability, a huge repository of softwares and the ease of installing them. If a person can install an app from appstore, one can definitely install softwares on openSUSE. This is one of the major reason why so many of friends and I love openSUSE.

This is what makes it ideal for the FOSS initiatives for humanity that we have currently started to undertake.
Moreover, unlike Windows and Mac, developing softwares in Linux is much lighter on the system. Making it is ideal for people with less hardware resources to bring their ideas-to-life.

openSUSE is one-of-a-kind tool that has the potential to lead our journey to make and achieve something great for the people. Over the past few years openSUSE user group in India hasn't seen much of the growth. This maybe because of the fame of Ubuntu in the country. Much of the people still don't know that there isn't one but many distributions of Linux to choose from. Free and open source softwares are all about the freedom of choice, and without making people know about the choices they have, freedom can't fully be achieved.

Various initiatives have been taken to by colleges and communities in India, including ours.

Pinyin input method is the most popular input method in China. There are many kinds of Pinyin input methods on ibus, such as ibus-pinyin, ibus-libpinyin and ibus-sunpinyin. All of them need search words from local table dictionary.
What is ibus? The full name of ibus is Input Bus Introduction. It is the default input method framework in SUSE Linux Enterprise and openSUSE GNOME Desktop. ibus-pinyin and ibus-libpinyin work on ibus. ibus and its input method are very important to Asia users of SUSE Linux Enterprise and openSUSE.
The cloud computing is the new feature in some commercial input methods in China. They can search and get words from cloud server. Cloud computing can greatly improve the accuracy of the input method.
This project is integrating cloud computing in ibus-pinyin or ibus-libpinyin. Many cloud pinyin input methods have apis can be used, Such as baidupinyin and googlepinyin.And Fcitx have finished this work, but it was just a extension on fcitx (fcitx-cloudpinyin).

K Desktop Environment or KDE is one of the most popular in Linux. Many features provided by KDE. This is my favorite desktop environment that I use everyday with openSUSE.

On this session I will talk about one of the cool features of KDE, namely Plasmoid, a simple script for the plasma engine. I am focusing on writing QML (Qt Modeling Language) script to create a Plasmoid. QML is a user interface markup language. It is a declarative language for designing user interface–centric applications. Inline JavaScript code handles imperative aspects.

On this talk I will explain how to create plasmoid as RSS feed reader, for example fetching RSS feed of openSUSE.id blog. This feed will be displayed on desktop if the blog was updated. Plasmoid will send a notification on desktop.

I will explain how to write QML code using Qt libraries, compile the plasmoid, install it on the desktop, and also give tips and tricks using QML to create other Plasmoid.
