ITEC summer dinner at Lake Wörthersee as a highlight of the academic year 🎉🤩😂

People seated at long tables on a covered lakeside terrace, enjoying lunch and conversation during a social gathering. The terrace overlooks the turquoise waters of Lake Wörthersee, with forested hills and mountains in the background, creating a relaxed setting for networking and informal discussions.

Major issues/bottlenecks during online video streaming and why we need analytics (ad: bitmovin.com/video-observ...)

Illustration of the “blame game” in video streaming quality problems. A circular diagram shows four stakeholders pointing responsibility at one another: the OS vendor blames the internet connection, the service provider blames the video/CDN provider, the video/CDN provider blames the user’s home network, and the consumer blames the device or app. In turn, the device/app vendor blames the operating system. At the center, two people point fingers at each other, highlighting the challenge of identifying the true cause of poor video streaming performance.

Happy National Streaming Day! (btw. why "national"?) en.wikipedia.org/wiki/Nationa...

Figure and ALT text created by ChatGPT based on link to Wikipedia URL.

A dark blue themed infographic celebrating National Streaming Day on May 20. Large bold text on the left reads “National Streaming Day” with a subtitle describing it as a day to celebrate shows, movies, and creators that entertain and connect people anywhere. On the right, a modern living room scene shows a large TV displaying a streaming interface with categories such as adventure, drama, sci-fi, comedy, and thriller. A bowl of popcorn, a remote control, and a coffee mug sit on a table in front of the TV.

Below, three information panels summarize key facts:

* “The Basics” panel lists the date (May 20), observed in the United States, established in 2021, and founded by National Day Calendar.
* “Streaming by the Numbers” panel highlights statistics about streaming adoption and viewing habits.
* “Ways to Celebrate” panel suggests binge-watching a favorite series, discovering something new, streaming together, and supporting creators.

The bottom banner encourages viewers to “Press Play” and celebrate stories that move them. The overall design uses glowing cyan and purple accents, streaming icons, and a sleek modern entertainment aesthetic.
