 No, it's not working. Alright, what happens if you stop sharing the screen? Okay, so I will try to... Yeah, yeah, yeah, yeah, do that one, okay. So... Okay. Let's go to the clock, okay. Okay. Okay. Alright. Now, let's start. Okay. Thank you. Hi. Sorry, so troubles. Hi. I'm Shinji Enoki and from Japan. This talk is how to use online office suite and data storage to protect your privacy. And just so... This talk has three topics. Firstly, summarized data privacy risk and needs. And second, solutions in the area of file sharing and editing, LibreOffice and QoibreOnline and NextCloud. And thirdly, so how to build NextCloud and QoibreOnline. And I'm mainly active in LibreOffice and Japanese team and so membership committee of TDF. And so other committee is, for example, so Japan Unix Society and more. Okay. And LibreInnichinomiya City, Japan in the Kansai area. Osaka and Kobe in the middle. Okay. And so first topic, so data and privacy risk. So we are so increasing using cloud service for many, many cloud services. And so it's a piece of convenient and so many, many benefits. However, it became difficult to manage our data. So there is a need to identify to assess risks. And growing risks and needs. Some case is risk of loss of control. So the reason is from the service providers, not only big tech. And so other case is a government-sized site. And so user privacy needs and compliance. So privacy culture and so roles are different from country to country. So making it difficult to respond. And so these are so moving, such a changing. So must be agile. And so illegal, of course illegal attack. But so this talk is so out of scope. And so risk of less control. And so they control your so availability and usability or so functionality. So it's a trade off. So engineering so cost or so time. We use control. So mostly so you need to the best combination. So private cloud and public cloud was on premise. So now we are open source people. And we want to use open source. Also it brings for great benefit to non-open source servers as well. First benefit, easy to control, transparent. Also this case is transparent and so active committee is key. So not to call transparent case is control is not easy. And second case is easy to provide products. Because so the same other production environment is immediately so available. And may not be a trade off. So good open source solution we greatly so reduce the cost of self hosting. And simple or much you are needs or so popular in important. Okay. So and additional information so. Sometimes so people talks digital sovereignty. So this is so difficult for the world. The term digital sovereignty is used mainly in Europe. So I have come to here in Japan as well, but not yet common. So my understanding is that there is a mixing. So industrial so policy towards big tech. And so for example, so Google or Facebook. And so protecting citizen policy privacy. And so democracy controlling privacy. So concept is mixing. And so this is probably a new concept. But it was so redefined as a new term because of the important. This is Tim. Okay. And second topic. So. And the rest of our online or next crowd. So all my heart sharing editing. And area. So. Corruption work is progress as all of us as well. Because now. So COVID situation. And so. You're like this online file sharing is becoming more than more and more important. And corporate. Collaborate editing is also important. Now. So. Next crowd plus online is. Most of the typical open source combination is this area. And. Next is very famous and so simple and so powerful file sharing file storage. And online is also collaborative. On the web. And this is so reverse based online office seat. And next is also many, many so function. So. File management. Best file management. And sharing, but not only so. Web. Browser. You can use as a web app. And the folder is sharing. So also patient possible. And so. Single sign-on and so file access control. Or sync with mobile and. Apps and PC client. And so. Many, many various apps. And. Commander email client task management. Chart or video conference. Including from the. Beginning. So file sharing. So case is also. Very easy to control. Some cases also allow. Editing. Check. Or file download password protect. So you can check in. And you can. And probably online. So starting very easy. So. You can click. So file name area. And so study. So. This case is many, many cases. Also. From large enterprise to home or. And in visual users. In Japan. And use case. I hear. So university case. Used by so. 35,000 people. Very big. Biggest. Use case. And personal use. Is. Many people using the. Personality. And. For example, so. Japanese. So Linux users group people. And my case. Think email file. And. Not only document file. This is also university. So. This is also Japanese. And so. From the. presentation. And so other case. Is. My. Active in the. So Japan. Society. It's also. Community. Unix user group. So very long time. So active. Society. And. This case. Using. One. Was. Almost. Same time. By four people. So maybe two hours. So very hard. So. Some of the function. Did not work well. But so. Work. Very, very. Easy to use. This. So. And so. So people is also. Copy and paste. And so from the email. And so editing. Changeings. Real time. It's very hard. But so almost okay. And so. Desktop. And online. Okay. So. Liberals on PC. And so. Cover online have the same rendering. Result. So. Firstly I created. And the template file. And so. Synchronize. Using the next crowd. So. Very easy to synchronize. And. And so one point. So be careful. Don't. So edit cover online. Cramp things. So. Cover online will. Detect it. Reload the file. Okay. Third topic. So how to build next crowd. And cover online. So. Time is very short. It's also. Checking the website. That's all. Very easy to. Install to the next crowd. So some options. So snap. Archive file. Maybe I. Recommend that. So snap. Easy. I mainly use. So snap. Okay. But so snap is not. Flexible. If you want to. You can use another. So solution. Another. And cover online install. So. Include in next crowd hub. However. App image. So difficult to. Add fonts. So Japanese tones or. Asian fonts. Not including. I'm not to recommend. For Asian people. I recommend. So. Finally. So. So. The package or. And you can check. So. So. And. This is. So. And import. So. So. So. So. And the configuration. So. So. So. So. So. So. So. So. So. So. So. So. So. And so. Sometimes so confused so. Next crowd app store has two apps. So. And next crowd. Office is a plug in for the cover. So. You need to install. This plug in. And. Build code server. This is so. App image. version. And the code is a collaborative online development part, a development edition. Okay. So, and so, finally, so, installed, and so, set up to the, on the next cloud, so, administrator, and click the office. And so, you can check the, so, built-in server or your own server, and URL, it's finished. So, server location is, so, next cloud and collaborative online can be separate servers. Collaborate online can be, so, scaled with HAProxy. So, and easy to combine private cloud and public cloud or on-premise. So, for example, so use collaborative online and HAProxy to scale in the public cloud. So, is this combination is best? I don't know. So, this is also very common tool, may not be as effective as that detect tools. So, and so, Microsoft Office can be read and write them, but not perfectly on the same level as LibreOffice. And, on the other hand, so, compatibility with LibreOffice is basically perfect if the same fonts are installed. Okay. And conclusion. And privacy is increasing now. Assessing with data or systems should be controlled is important. So, you can create a collaborative work environment using the next cloud and collaborate online. And so, you can support innovation by providing collaborate environment, while conciting the trade-off, so, between control and cost. Okay. And so, related talks at Fosnagia. So, in our opinion, these talks are already done and LibreOffice technology. And so, today's talk is, so, Michael Mix. He is also a collaborative productivity. So, and so, tomorrow is a Frank card check. And next cloud CDO. You can check. Okay. And we're finished.
