My Sharing about JavaFX

Attending JManc, an unconference organised by Manchester Java Community and hosted at Auto Trader's offices, was an exciting experience. This unique event demonstrating the essence of participant-driven learning and collaboration, set the stage for a series of engaging and enlightening sessions.

Propose and vote for topics

In the morning, we proposed topics using sticky notes. Afterward, we voted on these topics with dots, shaping the day's agenda based on collective interest. This process itself was a testament to the community's diverse interests and expertise.

Breakfast

Keynote by Helen Scott

Keynote by Helen Scott

The unconference kicked off with a keynote by Helen Scott from JetBrains. Helen's talk centered on AI, a topic so crucial and timely that, as she humorously noted, audience would have thrown her out of the window if she did not speak of AI. Her insights into AI's impact on development and the future of programming set a thought-provoking tone for the day.

New Features

The next session delved into the latest features in Java, highlighting enhancements that developers can leverage to improve their productivity. We explored the new switch syntax, Records, new Collections APIs, Java Modularity, and the Java Native Interface. Each feature was dissected to understand its benefits and potential use cases.

Troubleshooting Applications in Containers

Troubleshoot in Containers

This session focused on the challenges and solutions for troubleshooting Java applications running in containers. We covered stress testing with JMeter, analysing heap dumps, configuring Garbage Collection, and the division of labor between image building and container deployment. The practical insights shared were invaluable for anyone working with containerised Java applications.

Lunch

JavaFX, Home Automation and Stable Diffusion

JavaFX

After lunch, I had the pleasure of partnering with Neil Smith and Swapnil Gaikwad for a session on JavaFX. We discussed a range of applications, from home automation and image recognition to Java and Python integration, text-to-image generative AI, and game development. The collaborative nature of this session highlighted the versatility of JavaFX and its potential in various domains.

Java vs Other Programming Languages

In this session, we compared Java's capabilities with those of other popular programming languages like Kotlin and Python. We discussed Java's unique advantages, such as its robustness, extensive ecosystem, and long-term stability, as well as factors influencing its popularity.

Tiered Compilation

The final session of the day tackled Java's Tiered Compilation, an advanced topic that delved into the intricacies of the Java compiler. We explored how developers can fine-tune their applications for optimal performance by understanding the secrets of Java's compilation process.

Fault Injection - another interesting topic

JManc was a resounding success. Every participant brought their ideas, experiences, and knowledge, contributing to a vibrant and dynamic setup. The unconference format allowed for deep dives into a wide range of topics, fostering both learning and collaboration. A big thanks to the organisers and every helper who made this event possible. JManc was a fruitful activity that everyone is definitely looking forward to it next year.

Tales from Earthsea

Recommendation: please read the original novel series Earthsea before you watch the movie (Japanese: ゲド戦記, meaning the Story of Ged's Battles), otherwise you'd sleep very well in the cinema. I left some comment about this movie in other blogs , here is its English translation: I don't think that the problem of the movie is the fault of the plot, because the director Goro Miyazaki (Japanese: 宮崎吾朗) is not the author of the novel and the novel is an award-winning piece. The problem is that he selected a wrong media to express his own vision. First of all, the novel is not popular in Chinese society. Few people would spend hours to finish the books before watching the movie. The director selected to start the movie by the third book of the series, however. It would make audiences lose their way. This is because much background information has been described in previous book, say Tenar's experience in The Tombs of Atuan. Unlike his father Hayao Miyazaki (Japanese: 宮崎駿) as t

I am a HIP (hidden, inactive and passive) member. I had looked for any suitable activity, so I attended the gathering last Saturday. There were three guests to talk about investment in personnal opinions instead of standard words. This is the irreplaceable value of a private gathering. The first guest was a broker. He began with introduction of investment theories. In his opinion, investing in stock is like multi-level marketing. When a stock releases, an investor buys and introduces it to another. The second investors buys it and the stock price increases. And so on, until no following investor buys it to support the stock price and the price drops. This figure simply explained the relationship between the cash flow of the market and the stock price. The second guest was a reporter. Being a reporter, he has experienced many issues under table. He identified unstated relationships amongst various parties such as the authories, the academics, mass media, institutional investors and smal
