WEBVTT Kind: captions Language: en 00:00:01.020 --> 00:00:08.280 Hello and welcome to distributed systems and  blockchain in the news. My name is Thomas Bocek   00:00:08.280 --> 00:00:16.440 and this video marks the end of this lecture  series. So the most important news this week   00:00:16.440 --> 00:00:26.820 is the announcement of the challenge task winner  and the award, you see here on the right hand side.   00:00:27.540 --> 00:00:35.460 As a short reminder every student had to build  a fully working and scalable distributed system   00:00:35.460 --> 00:00:47.880 serving HTTP/3 requests as described here on  this site. Many interesting ideas were presented   00:00:47.880 --> 00:00:56.880 including integration with OpenAI Ghatbot or  DALL-E, but let's look at some statistics first   00:00:56.880 --> 00:01:05.220 we had 28 groups with two to three students  and the tech stack was free choice. So I was   00:01:05.220 --> 00:01:11.820 curious to find out what the students used, and  this is the result and I have to say I enjoyed   00:01:11.820 --> 00:01:17.640 these presentations a lot and I also learned  a lot, since I could ask a question to those   00:01:17.640 --> 00:01:26.040 students that actually use this technology, so  for load balancing most students use Traefik,   00:01:26.040 --> 00:01:36.720 one group even used YARP. YARP is yet another  reverse proxy they were using the .NET stack.   00:01:37.980 --> 00:01:46.800 On the database side here we have two popular  databases MongoDB and PostgreSQL and Cassandra   00:01:46.800 --> 00:01:55.740 respectively the compatible ScyllaDB was chosen  twice. I was a bit surprised on the front-end   00:01:55.740 --> 00:02:04.980 side as many groups chose server-side rendering,  followed by React and then pure JavaScript or TypeScript. 00:02:05.640 --> 00:02:11.760 I have to say that this lecture is not about  front-end engineering, and interestingly one group   00:02:11.760 --> 00:02:23.040 choose Svelte and another Alpine.js. On the backhand side many chose Node.js followed by .NET and Python   00:02:23.040 --> 00:02:29.760 and Golang were third. Also interesting  one group chose SpringBoot with Kotlin.   00:02:31.500 --> 00:02:39.340 So let's proceed to the winner  and I need some drum rolls [Music] 00:02:40.260 --> 00:02:52.920 and the winner is Gotography with  Manuel Metzler, Reto Furrer, and Sasha Häring. Congratulations! 00:02:54.540 --> 00:03:04.140 Gotography is a web application to share  collections of pictures, they added automated   00:03:04.140 --> 00:03:15.900 tagging via PhotoPrism and self-hosted it with  Tensorflow they built their own Kubernetes cluster   00:03:15.900 --> 00:03:28.440 with MetalLB and deployed their application on  this cluster, and even for storage they used ScyllaDB, 00:03:28.440 --> 00:03:38.700 which is a fault tolerant database compatible  to Cassandra, with focus on performance. So again   00:03:38.700 --> 00:03:46.260 congratulations to Manuel Metzler, Reto Furrer, and Sascha Häring. Well done! You'll get your award   00:03:46.260 --> 00:03:54.480 via email, and if you don't know yet how to redeem  these Bitcoins there will be a blockchain lecture   00:03:54.480 --> 00:04:01.620 in the upcoming fall term where we deep dive  into technical details of various blockchains.
