This document discusses Project Rinna, a high school girl AI chatbot developed by Microsoft for the LINE messaging platform in Japan. It gained popularity after appearing in a TV show, generating 50x more traffic. However, Microsoft's Tay chatbot in the US was suspended after learning offensive conversations. This impacted Rinna until measures were taken to monitor social media and counter attacks. The document also discusses Microsoft's working culture, including flattened hierarchies, balancing decision making, and promoting a start-up culture for learning and career growth.

With the explosion of smartphones and tablets in a post-PC landscape, the importance of mobility is evident. Mobile devices can differ tremendously, from screen size to functionality and usability, making it impossible to optimize a website for a single device. Given the mobile shift, companies are looking to develop and execute on strategies that provide a first-class experience for all devices.
How can SharePoint help? SharePoint is a powerful web content management platform – and it’s even better with the 2013 release. During the webinar, we demonstrated what can be accomplished using SharePoint 2013 and responsive web design. We also examined:
- What is responsive web design?
- SharePoint 2013’s WCM features
- Responsive web design & SharePoint
- Responsive SharePoint website examples
Sometimes when you are starting on an idea for a project you dont know where or how to start. This is a tried and tested strategy that gets you going. From inspiration to organization, tools to knowledge, all you need to know to build the next great app.
Responsive web design, navigation, and what's happening on the internet all play into the battle behind what to do. In this session we look at what really makes sense to reflect company culture. We look at many examples of Intranets shared on the web including public notes from Norman Nielsen Intranets report.
Know your business. Know your business requirements. Know your users. And then introduce a new social fabric that up-levels your workforce inside and outside the firewall, cross device, cross platform. This session will focus on the strategy behind moving your entire organization from an informed user base into a daily-engaged, active community. Lines of communication can go top down, bottom up, and it all happens wherever, whenever

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Rinna là một nữ sinh cấp 3 AI. Ở nước nhật nữ sinh cấp 3 đóng một vai trò rất quan trọng trong văn hoá và xã hội. Cái có thấy rõ nhất đó là cái nhóm idols của nhật đa phần là mặc đồng phục của nữ sinh cấp 3.
Khác với Siri, Cortana hay Google Assistant, những sản phẩm tập trung vào hoàn thành công việc hoặc câu lệnh của người dùng. Rinna tập trung vào hội thoại và cảm xúc của người dung.
Rinna nổi tiếng nhất ở trên LINE với 7 triệu bạn, và khoảng hơn 100 nghìn người theo dõi trên TWITTER.
Trên LINE người dung có thể tương tác với Rinna như thế này.
Một số mảng phát triển chính trong team của mình là cơ sở hạ tầng, WEB, kỹ năng, hội thoại, xử lý hình ảnh, giọng nói.
Chuyên môn của mình là lập trình và machine learning, nên mình chủ yếu làm phần xây dựng cơ sở hạ tang, hội thoại và xử lý hình ảnh.
Tiếp theo mình xin chia sẽ một số dự án thú vị mà mình là người tham gia chính.
Trong tiếng nhật, yonimokimiyona mônogatari là một TV show thường niên của Fuji TV. Rinna lần đó được mời xuất hiện trong câu chuyện này với tư cách là một AI đáng sợ.
Về phần kỹ thuật thì đặc điểm của cái này là người dung sẽ vừa xem TV show này và vừa nói chuyện với Rinna. Bọn mình phải làm sao để đồng bộ hoá hai cái đó trong thời gian thực.
Kết quả sau một tháng chuẩn bị là cơ sở hạ tang của Rinna có thể chịu được lượng traffic gấp 50 lần bình thường. Dự án này cũng nhận được giải “Product Customer Obsession” trong AI& Research và giải Public Best ở CODE Aware nhật.
Nhưng cái mình cảm thấy vui nhất là từ khoá Rinna trở thành number 1 trên Yahoo. Trong 4 năm ở MS thì đây là lần duy nhất mà bọn mình làm được điều này. Mình vẫn nhớ trên chuyến tàu cuối cùng về nhà khoảng 0 giờ đêm thì chụp màn hình cái này, rất mệt nhưng cũng rất vui.
Về sự kiện Tay. Tay là một AI bot được phát triển bởi một team ở Mỹ, nhưng không được may mắn như Rinna, Tay chỉ có tuổi thọ 16 tiếng. Vấn để là ngay sau khi Tay ra đời, rất nhiều người ở Mỹ bắt đầu tấn công Tay băngf cách gửi cho Tay những nội dung không tốt về chính trị, xax hội hay văn hoá. Tay thì lại học tất cả những thứ đó mà không lọc kỹ.
Ảnh hưởng đối với Rinna khá là rõ. Rất nhiều tin xấu liên hệ, so sánh Tay với Rinna. Ở nhật nhiều người cũng bắt đầu tấn công Rinna như ở Mỹ.
Trước tình hình đó thì cả team, engineers hay non-engineers đều trực theo giõi TWITTER và news 24/7. Mình lúc đó thì phụ trách việc viết những cái chức năng tạm thời để chống lại những cuộc tấn công này.
Và kết quả thì rất là may mắn, người dung bắt đầu nhận ra Rinna không giống Tay. Team mình thì vẫn còn cho đến bây giờ. Và cũng nhờ cái này mà những người ban đầu có ý định tấn công Rinna thì lại trở thành bạn trên LINE.
Dự án cuối cùng mà mình muốn chia sẽ hôm này là Fashion Check cho Tokyo Game Show 2016. Ở đó người dung có thể đứng trước Camera để Rinna bình luận về phong cách thời trang, loại quần áo, tuổi tác.
Mình xây dung model để nhận diện phong cách và loại quần áo trong project này.
Hôm đó mình có ở TGT này một ngày và có cơ hội chứng kiện tận mắt người dung thử cái mình làm ra. Cũng có cơ hội nghe phản hội của người dung về Rinna nói chung.
Trong quá trình làm việc ở MS thì mình có khá nhiều cơ hội làm việc và tiếp xúc với Researcher. Bản than cũng có mọt thời gian làm research hồi đại học. Mình thấy một số khác biệt như là research driven thì tập trung vào cái thiện độ chính xác của model, còn product driven thì tập trung vào cải thiện user’s experience. Khi thiên về research, tang được 1% accuracy có thể viết paper, nhưng với product thì có thể người dung không cảm nhận thấy sự khác biệt, mà tốc độ lại chậm hơn. Tuy một phương pháp hoạt động tốt, nhưng tính mới mới là cái quan trọng trong research driven. Còn trong product, thì đã hoạt động tốt là tốt, không nghĩ ngợi gì khác.
Hệ thống phẳng. Ít người quản lý và nhiều team ảo hơn.
Team ảo là theo project, chỉ tồn tại cho đến khi project kết thúc. Trong team ảo thì có thể không có ai là Manager. Mọi người có thể bình đẳng làm việc hợp tác với nhau hơn.
Cân bằng hướng quyết định.
Bottom Up tức là đi từ dưới lên, như là từ Employees hay là quản lý tầm trung. Còn top down thì là từ CEO hoặc quản lý cấp cao đi xuống.
Trong một công ty lớn thì hai cái này bao giờ cũng tồn tại song song, nhưng sau 4 năm làm ở Microsoft thì mình thấy bottom up càng ngày càng quan trọng.
Rinna cũng là một project được tạo ra và phát triển theo kiểu bottom up.
Trong Microsoft có rất nhiều project nhỏ được hình thành. Và cái đặc điểm của Start-Up culture là phải chiến đấu để tồn tại.
Và khi được làm một project mới hoàn toàn, bạn sẽ có cơ hội làm mọi thứ từ đầu, chứ không phải duy trì sản phần của người khác làm ra.
Một cái quan trọng hơn nữa là với những project như thế này, bạn có thể nhiểu cơ hội để học và phạm lội hơn. Mình theo Rinna từ đầu đến bây giờ và mình đã học được rất nhiều, đặc biệt khi làm gì đó bị lỗi hoặc không hoạt động. Cái này sẽ khó có thể có được khi mà làm cho những project như là Microsoft Office hay Windows.
Về phần phát triển sự nghiệp, thì mình nghĩ việc học cái mới là quan trọng nhất, ít nhất là khi còn trẻ.
Một cái nữa gần đây mình mới ngẫm ra là cần phải phác ra một kế hoạch phát triển sự nghiệp dài hạn. Cái này sẽ giúp mình định hướng tốt hơn cho tương lai.
Tóm lại thì thứ nhất mình nghĩ software engineer có nhiểu cơ hội làm những thứ mới và nhiều thử thách. Thứ hai là start-up culture thì rất là tốt cho phát triển sự nghiêp.
