  • Performance Limitations
    While sufficient for most use cases, Regex101 may struggle with very large datasets or extremely complex regular expressions, causing performance issues.

  • How can I learn Java Backend development
    IDK if his Udemy course ("Spring Boot E-Commerce Ultimate Course") is relevant to what you are trying to learn, but I want to commend Nam Ha Minh as someone who has answered every question I asked about the course material within 24 hours. There aren't many teachers like that, it seems, so it seems worth praising those that do this. Maybe other teachers will feel more encouraged to follow suit if they see the...

  • Self study using book
    From what I read, there are examples to work though, so you will get hands-on coding experience. Even more important, one review refers to the author replying to a reader with a question about one of the examples. Finding teachers that actually respond is rare, in my experience. I've only found one with such a commitment to his students, to date: Nam Ha Minh of the codejava website and author of a few udemy... Source: over 4 years ago
  • Spring Core
    Of the various tutorial sites, I have found the content at codejava.net to be reliable and well written. The author doesn't just regurgitate documentation specs and examples, but puts time into creating additional, original examples that help clarify things. He has many tutorials that are Spring based. I don't know what books to recommend--I've been learning Spring most via tutorials and Udemy classes. Source: over 4 years ago
  • java.lang.ClassNotFoundException
    But after formation of my jar file, it is not running. I know that this is silly application but I am not getting why my application is not running. So can you look at my code and can give where I am making mistake. I am making some mistake in making jar file. I have taken part of code from codejava.net and so package name is I kept net.codejava.networking. Source: about 5 years ago

  • What Happened to WebAssembly
    To add to the authors list of examples, the regex test site Regex 101 (http://regex101.com/) relies on WebAssembly. To verify this in Firefox, you can set javascript.options.wasm to false, and you will be instructed to use a browser supporting WebAssembly. If you're willing to risk some safety guarantees, then you can use SQLite in Go without cgo if you rely on wasm builds of SQLite. In particular, this package... - Source: Hacker News / 6 months ago
