    Compare PDFs Visually
    https://hackaday.com/2022/08/06/compare-pdfs-visually/

    Sometimes a problem seems hard, but the right insight can make it easy. If you were asked to write a program to compare two PDF files and show the differences, how hard do you think that would be? If you are [serhack], you’ll make it much easier than you might guess.

    Of course, sometimes making something simple depends on making simplifying assumptions. If you are expecting a “diff-like” utility that shows insertion and deletions, that’s not what’s going on here. Instead, you’ll see an image of the PDF with changes highlighted with a red box. This is easy because the program uses available utilities to render the PDFs as images and then simply compares pixels in the resulting images, drawing red boxes over the parts that don’t match.

    The best thing we can do today to JavaScript is to retire it,’ says JSON creator Douglas Crockford
    By Tim Anderson -August 4, 2022

    Crockford made this assertion in an interview last month:

    “The best thing we can do today to JavaScript is to retire it. Twenty years ago, I was one of the few advocates for JavaScript. Its cobbling together of nested functions and dynamic objects was brilliant. I spent a decade trying to correct its flaws. I had a minor success with ES5. But since then, there has been strong interest in further bloating the language instead of making it better. So JavaScript, like the other dinosaur languages, has become a barrier to progress. We should be focused on the next language, which should look more like E than like JavaScript.”

    JavaScript is the world’s most popular programming language according to most surveys
    According to a StackOverflow survey earlier this year, JavaScript is used by over 65% of developers, way ahead of second placed Python at 48 percent (ignoring HTML, CSS and SQL which are not general purpose languages). It is an unlikely achievement considering its origins.

    Brendan Eich invented the language for Netscape in 1995, apparently in just 10 days. “In May I did 10 days of hard work, I didn’t sleep much,” Eich told the dot.JS conference in 2018.

    Eich called the work “a rush job” but also said that “I knew there would be mistakes, there would be gaps, so I made it very malleable as a language. That has enabled web developers to make it be what they want it to be.”

    Why has JavaScript been such a wild success?

    There are multiple reasons, including Eich’s foresight, ease of learning, and tolerance of code that would be mistakes in many languages, like comparing strings to numbers and getting a common-sense result – though Eich later called this “a big regret, because that breaks an important mathematical property.”

    Another big factor is that Google’s determination to make browser-based applications competitive with the desktop gave the world the V8 engine (2008), which along with Mozilla’s SpiderMonkey and Apple’s JavaScript Core gave the language amazing JIT-compiled performance. In 2009, Ryan Dahl came up with Node.js, enabling V8 to run outside the browser. Dahl had server applications in mind, but today Node.js and NPM (Node Package Manager) are also essential to the development process for most web applications.

    Development process? Part of the problem referenced by Crockford is that along with increased capability JavaScript has acquired lots of complexity, and a typical application today includes a build process using WebPack, Rollup or some other bundler, a long way from Eich’s original concept.

    Should we call Rust a Failed Programming Language?
    Rust has been ranked as the most liked language by its users for two years in surveys but programmers say otherwise

    GOOGLE’S CARBON CAN DO WHAT RUST CAN’T! OUTPERFORMING C++ IN PROGRAMMING
    https://www.analyticsinsight.net/googles-carbon-can-do-what-rust-cant-outperforming-c-in-programming/

    The latest programming language of Google, named Carbon will bring back the glory days of C++
    Google Principal Software Engineer Chandler Carruth introduced Carbon this week at the “CPP North” C++ conference in Toronto. The purpose of this new work-in-progress programming language is to convert the C++ codebases in a better way than Rust. According to experts, Rust doesn’t have the same bi-directional interoperability as other tools, which introduces a type of language barrier when translating between different programming languages.

    Now, What makes Carbon Better than Others?
    What makes Carbon better suitable than Rust is its introducer keywords and simple grammar. Carbon’s unction input parameters are read-only values and the pointers provide indirect access & mutation. The writer can use expressions to name types and the package is the root namespace. The user can also import APIs through their package name. For Carbon, the explicit object parameter declares a method and it has a single inheritance. There are further benefits that extend beyond Carbon’s language, including ethical motives like the accessibility and inclusivity of the project’s culture.
