Welcoem to posts!!
in the future - u will be able to do some more stuff here,,,!! like pat catgirl- i mean um yeah... for now u can only see others's posts :c
I am working on a video about "Designing for Scalability vs. Designing for Performance" - which I hope I will be able to publish within the next 2 weeks. It is not so much about the actual techniques, but more about how these two approaches will affect the product, your scaling costs, and your team skills.
Do you have anything questions or input?

My next video will be about Java Generics (unless something unexpected happens). It will probably take a week or so before I can release it - depending on how much free time I can find to finish the recording, code examples etc. - but it's coming :-)
I am also working on a few other videos at various stages. I will talk more about those once they are getting closer to ready :-)

To those of you that are into P2P networks, my P2P book is available on LeanPub.com - payment optional :-)
It's still under 50% finished, but there is enough to for a reader to start understanding the basics of the P2P topologies that exist today.

My Java Concurrency video playlist now contains 26 videos covering various aspects of Java multithreading and concurrency - including virtual threads 😊

Are there still some topics missing, you think?
#Java #JavaConcurrency #JavaMultithreading #Parallelism

My next video will be about the Java ForkJoinPool - as I have received quite a few requests for making a video about this topic 😊
Parallelism is the trick to harness the growing power of modern CPUs - and GPUs , as the CPUs themselves do not advance as fast in clock speed anymore.
In the same category we have exciting projects like TornadoVM and Project Babylon which are bringing GPU compute to the Java platform. 😊 #Java

There is a lot more to be said about peer-to-peer (P2P) networks than what I have mentioned in my now 12 years old P2P Basic Algorithms video.
I have discovered more topologies that I did not know existed when I made the first video.
Also, a good bit has happened since then. Among other things, I have designed my own P2P network topology - which I believe is a good alternative to the existing topologies.
I am currently making notes for several new videos about P2P networks, which will go into more detail about this topic. I hope you will find them interesting :-)

A few weeks ago I was interviewed on the Smart Cherry's Thoughts YouTube channel - about my work history, about AWS and other things. Sai asked me a lot of questions and I tried to answer them as well as I could :-) The interview is here:

Hey - I consider doing some "ask me anything" style videos - answering your questions if you have some good questions :-) Would that be interesting? If yes, you can ask some questions in the comments below, then I will see if I can answer them, and if yes, I might turn them into videos (or simply answer them in the comments below if the answer is short ;-) )
P.S. I am still working on the first video in the software design series. I think I've got the slides figured out, but I have to double check that the "theory" holds (doesn't have holes, or is unclear etc.).
24 - 15
In my poll from 3 months ago, I asked if you are interested in the topic of Design Patterns etc.
95% of respondents answered "Yes". Therefore, I am currently working on the first video in a series in this area. However, rather than merely repeat what you can find in other books and videos, I will share my own approach to software design and design thinking - and explain how that relates to other well-known design principles. Feel free to share your feedback with me as the videos are published :-)
98 - 12
Are anyone here interested in the topic of Design Patterns and Compositional OOP ?
I am thinking about which larger topic to tackle next, as there are not that many Java Concurrency topics left to do (still 5-10 possible - but not much more).
21 - 24
Hi, I make videos about software development related topics like Java, web development etc. Occassionally I'll drop a video or two about career related issues too. Oh, I also run the tutorial website tutorials.jenkov.com .
I try to cover each topic in reasonable depth. My own experience has been, that the deeper my understanding of topics within software development is - the better and faster a developer I become.
I started programming around 1987 (around age 12) on the C128 - in C128 Basic - then on the Amiga 500 in AMOS and Assembler, then later PC and C. I started working with software as job from 1998 as web dev, and from 1999 as Java + web dev, so I've been in the game a long time :-)
From around 2000 and forward I have mostly been working as a freelance, onsite consultant with Java, web and distributed systems deelopment. I love being self employed - but it's a lot of work.
