I/O Extended 2024 Incheon Review

I/O Extended 2024 Incheon Developer Conference was held.

It took place at "Songdo Convensia" with a total of 42 sessions from 13:00 to 19:00 on a large scale.

First, I received a T-shirt along with check-in and was able to choose and take a sticker.

Among the session areas of AI/ML, Web, Flutter, Server, Android, OpenSource, General, and ETC, I attended 5 sessions: 3 Web sessions and one each from OpenSource and ETC.

It seemed to be prepared at a level that would help developer trainees or juniors, and since it was expected, I wasn't too disappointed. There were quite a few takeaways from the practical experiences and examples shared.

[Web] Exploring Modern Web JavaScript Frameworks Together (Lim Seong-ho)
- 😌 I was relieved as many parts were familiar, thinking "I'm keeping up with the trends."
- 😮 I hadn't paid attention to remix because of NextJS and React, but I became a bit interested upon learning about View Transition.
- 😮 I only knew SolidJS existed, but I found it very similar to React, and it showed parts that offered even better DX, which was intriguing since it doesn't use Virtual DOM.
- 😲 He shared a quote from Amazon's CTO during a speech, which was an impressive statement. (Details at the bottom)
[Web] There's a Smart Component on the Other Side of the Sea (Kim Jin-seok)
- 😅 I was surprised as it unexpectedly dealt with .NET and Microsoft, but the speaker was witty, making the session fresh and fun.
- 😲 He presented the concept of Smart Components in Introducing .NET Smart Components – AI-powered UI controls, which might be difficult to implement in practice, but provided insight.
[Web] Sharing E2E & API Test Automation Cases in Web Application Service (Shin Hye-yeon)
- 😮 It was a good session as she detailed the examples used in practice and the problems encountered. I learned what to be careful about when adding tests to Lambda in the future.
- 🥲 I empathized with the reality that relying on human effort for final E2E tests is practical.
[OpenSource] Creating a Culture of Open Source Contribution and Sharing Together - A Story of Helping 100 Developers to Create Over 100 Open Source PRs and Change the World (Kim In-je)
- 🥲 The main point that contributing to open source isn't difficult is known, but it’s not easy...
[ETC] Monitoring Everything Happening in Applications Using Datadog (Yoon Chang-hyun)
- 🤩 Almost all monitoring seems possible, and it appears to have all the necessary business features like user funnel analysis, so I could integrate everything I was previously using like Sentry, Hotjar, and Amplitude into Datadog.
- 🤩 There are many features, and it doesn't feel lacking. In fact, many aspects seem even better.
- 🥲 It's hard to utilize the free version; due to costs, it would be difficult to apply to personal projects...
