Java features and specs

  • Platform Independence
    Java is known for its portability across multiple platforms via the Java Virtual Machine (JVM). This means you can write code once and run it anywhere.
  • Large Standard Library
    Java boasts a comprehensive standard library, which facilitates development by providing pre-built solutions for a wide array of programming tasks.
  • Robust and Secure
    Java emphasizes strong memory management and has built-in security features, making it a reliable choice for applications requiring high levels of security.
  • Community Support
    With a vast and active community, ample resources are available for learning and troubleshooting. Numerous libraries and frameworks are available due to its long-standing presence.
  • Performance
    Modern Java versions offer performance that is generally very good for many applications, particularly server-side applications where the Just-In-Time (JIT) compiler can significantly optimize runtime performance.

Possible disadvantages of Java

  • Verbosity
    Java's syntax can be verbose compared to newer languages, requiring more lines of code to accomplish the same tasks, which may reduce readability.
  • Memory Consumption
    Java applications can be memory-intensive due to their reliance on the JVM, which can be a downside for resource-constrained environments.
  • Performance Overhead
    Despite its generally good performance, Java's reliance on the JVM introduces some overhead compared to languages that compile to native machine code, such as C++.
  • No Low-Level Programming
    Java abstracts away from the hardware, making it less suitable for low-level programming tasks that require direct hardware manipulation, such as embedded systems programming.
  • Slow Startup Time
    Java applications can have slower startup times due to the overhead of JVM initialization, which can be a drawback for desktop applications or command-line tools that are frequently started and stopped.

Pharo features and specs

  • Integrated Development Environment
    Pharo offers a highly integrated development environment with powerful tools like the inspector, debugger, and playgrounds, enhancing the overall development experience.
  • Live Code Changes
    Pharo supports live coding, allowing developers to make changes and see the effects immediately without the need to stop and restart the application.
  • Rich Libraries
    Pharo comes with a comprehensive set of libraries and frameworks, reducing the need to search for external dependencies and allowing for rapid development.
  • Object-Oriented Language
    Pharo is a true object-oriented language, which makes it natural for modeling real-world scenarios and leveraging the power of polymorphism and inheritance.
  • Community and Support
    Pharo has an active and supportive community that contributes to continuous improvements, tutorials, documentation, and libraries.

Possible disadvantages of Pharo

  • Niche Ecosystem
    Pharo's ecosystem is relatively small compared to more mainstream programming languages, which might make it harder to find libraries, tools, and examples for specific needs.
  • Learning Curve
    Pharo can have a steep learning curve, especially for developers not familiar with Smalltalk or the unique aspects of its environment.
  • Limited Job Market
    Compared to more popular languages like JavaScript or Python, the job market for Pharo developers is limited, potentially making it less attractive for career-oriented developers.
  • Performance Constraints
    While suitable for many kinds of applications, Pharo’s performance might not be on par with languages specifically optimized for high-performance computing or low-level system programming.
  • Documentation
    Although improving, Pharo's documentation may not be as extensive or as easy to navigate as that of more widely-used programming languages, which can be challenging for new users.

  • Can someone help with port forwarding?
    You can use UPnP PortMapper. Source code/Download. All you need is Java and that's it. Hope this helps. Source: about 3 years ago
  • PolyGlot 3.5 Release
    I would definitely suggest installing Java for this one, and the error should have asked you to do so. I'll have to look into why that was not popping properly for you and address it in a bug fix. In the mean time, you can address the issue by going here to install Java: https://java.com/en/.

    Https://java.com/en/ Is this the java you're using to install optifine. When I first got optifine I thought java meant Minecraft and not java. Source: over 3 years ago
  • I keep getting this error when I try to install Worldpainter
    I had this problem before just go to https://java.com/en/ and download the java then you will have to install the actual java, then after its installed go to This PC then Windows then Program Files then Java then go to the file name file name that show I think when you downloaded it then go into bin and you will find a java.exe file then click it and World Painter will install and that's who I solved king problem...

  • _M2dir: Treating mails as files without going crazy
    Pharo/SmallTalk seem to also explore the ideas akin to this. (https://pharo.org/) to be fair the current state of affairs is similar enough with file extensions + mime info if you squint hard enough and pretend that app and systems folders files don't exist but it's held with pinky promises. - Source: Hacker News / 12 months ago
  • Enlightenmentware
    Smalltalk and as a particular case Pharo is an example of this for me. (https://pharo.org/). When I was in uni a paper that I always came back to was Licklider's 1960s paper on human-computer symbiosis (https://worrydream.com/refs/Licklider_1960_-_Man-Computer_Symbiosis.pdf) "[...]to enable men and computers to cooperate in making decisions and controlling complex situations without inflexible dependence on... - Source: Hacker News / 12 months ago
  • Why don't schools teach debugging, or, more fundamentally, fundamentals?
    I think in part it's because the idea that programming is text and math-based is too ingrained in society. For example, we talk about programming languages. But IMO there are also programming systems such as Smalltalk [1]. I've programmed 2 years professionally in it, currently looking for an engagement in a different language (a curiosity thing, also a resume thing). I think Smalltalk has a lot to offer by... - Source: Hacker News / over 1 year ago
  • Ask HN: What perfect software did you discover of recent?
    Glamorous Toolkit (https://gtoolkit.com/) and the underlying Pharo (https://pharo.org/). Writing Pharo code (a modern implementation of Smalltalk) in the GT environment is the most fun I've had programming in years. - Source: Hacker News / over 1 year ago
