“If we march into that village and we start trying to persecute people for using poison, something that's very illegal, nobody's going to talk to us. We're not going to find out where the poison came from. We're not going to be able to shut anything down. We should take the approach that people are using poison because they're desperate, because they see no other alternative.” – Andrew Stein Andrew Stein is a wildlife ecologist who spent the past 25 years studying human carnivore conflict from African wild dogs and lions in Kenya and Botswana to leopards and hyenas in Namibia. His work has long focused on finding ways for people and predators to coexist. He is the founder of CLAWS , an organization based in Botswana that's working at the intersection of cutting-edge wildlife research and community driven conservation. Since its start in 2014 and official launch as an NGO in 2020, CLAWS has been pioneering science-based, tech-forward strategies to reduce conflict between people and carnivores. By collaborating closely with local communities, especially traditional cattle herders, CLAWS supports both species conservation and rural livelihoods—making coexistence not just possible, but sustainable.…

Writing a book. Does it make you rich and famous? (#67) 1:15:28

hace 8 weeks1:15:28

1:15:28

Let me share a personal story. I started experimenting with Java on a Raspberry Pi about five years ago and blogged a few articles about it. But the more I experimented, the more I wrote down, and eventually, I had written a book… I worked on it for six months in a row, every evening and a lot of weekends. But the moment I received the box with my author copies was an incredible feeling. Holding a paper book with your name is a special moment. Fast forward to now. The 1000 paper copies are sold out. I have the last 10 copies in case you still want one ;-) But as I self-published the ebook, it's still for sale on Leanpub, and I keep updating it. That's one of the first significant differences between publishing a paper book and an ebook…. As an author, I got about 2 euros per paper book from the publisher, and LeanPub pays 80% royalties. Don't forget that I have to pay taxes on what I earn. So, if you do the math, you'll understand that the book didn't make me rich. But yes, it helped me in my career and was one of the reasons I became a Java Champion. So, we can argue about the "becoming famous". But that's only my story. I invited several guests to share their knowledge about book writing: Marián Varga is finishing a book and tells about publishing a book with a publisher. Wim Deblauwe wrote a few books and has much experience with self-publishing. Len Epp is the co-founder of Leanpub, so he can tell us a lot about ebooks. And we start with Trisha Gee, who wrote a lot of books!

How do we keep our Java applications up to date and secure (#63) 43:12

hace 18 weeks43:12

Last month, I published a Foojay blog post about the risks in systems that are stuck on old or outdated Java versions and got a lot of feedback from developers. Most of them want to move on but get stuck on management decisions, outdated production environments, or one of the many other reasons that keep systems stuck on old Java versions and dependencies... Do you want to bring your system from Java 8 to 23? Did you know that Java 17 already got 13 security releases? And that you can use tools like OpenRewrite to help you update your code?

AI, LLMs, ChatGPT—these are just a few of the buzzwords of the massive revolution unfolding right now. These tools are reshaping how we work, but they come with a catch: while they help us work faster and smarter, we need to be careful about placing too much trust in them.

38:04

Foojay Podcast published in November 2024 All info, show notes, and links: https://foojay.io/today/category/podcast/ At Devoxx and JFall, we talked with Georgios Diamantopoulos, Lutske de Leeuw, Tom Cools, Jessica Siewert, and Rijo Sam about staying physically and mentally healthy as software developers.

This is part 4 of the JCON interviews. In this episode, we have 5 new guests for you. We start with garbage collectors and Intelligence Cloud, a tool created by Azul to find out which of your code is actually used in production and which dependencies are known to have vulnerabilities. My colleague Gerrit Grunwald was at JCON to give a talk about these subjects. With Balkrishna Rawool we dove into Virtual Threads, a very interesting topic as concurrency and threads can be challenging... Piotr Przybyl came to JCON to give a talk about Test Containers and how to test your application in an environment that is similar to your production environment. Another important topic related to testing is Flaky Tests. How do you handle tests that only fail from time to time and make your whole test report unreliable? François Martin had a talk about this subject, and he came to the conference together with Annelore Egger, who was one of the many volunteers.
