#Clojure programming

[vanilla-voyeur]

Very amused every time someone discovers the ultimate way to do OOP in its truest, most polymorphic, most object-oriented form and its just immutable classes with public instance variables and no methods and no inheritance being transformed through singleton classes with no instance variables and one side-effect-free method, potentially taking a function as a parameter or returning another single method class. Brother you just reinvented functional programming.

I'm back

Oh wow, it's been 5 years since last post.

This time I plan to use this little corner of mine on Tumblr to share about LISP programming languages (be it Racket, Clojure, Common Lisp etc)

[not-toivo]

So, a month ago I finally got a job as a frontend dev, so, hooray,🥳, I now get to enjoy ✨Vue✨ and ✨Nuxt✨ 5 days a week and get paid for that. But since I've been unemployed for a very long time, this sudden change means that I'm even more tired to learn new things in my spare time, and also that there isn't much spare time now. I haven't posted much here before and so it seems I'm unlikely to be more active here in the future. Sad.

I did, though, try to read the 1st book on the list from the website Teach Yourself Computer Science, the one called Structure and Interpretation of Computer Programs (the reason for me to do that is because I don't have any STEM background, and, I guess, if I want to continue a career in a sphere rapidly encroached by AI, it's good to have some fundamental knowledge). I read about a ⅕ of the book, finally understood what it means for Haskell to be called a "lazy" language, but the exercises at the end of the chapters are too hard and math-heavy for me. Also, sad.

The book uses a programming language from the LISP family, called Scheme. I thought I could get by by installing Clojure instead, but that journey ended with the VS Code extension for Clojure, called Calva slowing down and then completely corrupting (?) WSL connection, so that I had then to reinstall my WSL "instance". (Yes, I use Windows, because I'm not a programmer). Which is sad, because the extension looked good and feature-heavy, it just couldn't function well in WSL environment for some reason…

After that, I installed Racket (another LISP) on the freshly reinstalled WSL distro, but then I couldn't pick up the book again and continue learning for, like, a week and a half, which is where I am at now. (Racket allows to define arbitrary syntax/semantics for the compiler, which in turn allows developers to create new domain specific languages distributed simply as Racket packages, with one of those packages being the dialect of Scheme used by SICP, the book mentioned earlier).

There is also the PureScript book, Functional Programming Made Easier by Charles Scalfani, which I'm unlikely to finish ever. The language is neat (it's very similar to Haskell, but compiles to JavaScript), but a bit overcomplicated for a simple goal of making interfaces. I do think, however, that I might try learning Elm at some point: the amount of time I've spent at work, trying to understand, why and at what point the state of some component mutated in a Nuxt app is, honestly, impressive, and I want to try something built around the idea of immutability.

im a full time lisp lover. between clojure for services, common lisp for low-level stuff, and janet for scripting i basically don't have to touch a language with significant commas for any personal project. but between you and me everyone who constantly talks about how great and mindblowing lisp is is a total moron. i just like expressions! and prefix notation! literally every advantage other than those two is now spread through like every new programming language. oh lisp is homoiconic? that blows your little mind? i have great news about EVERY LANGUAGE WITH MACROS. FUCKING RUST HAS MACROS. most people think writing the ast themselves is not a positive! the reason you think it's a positive is because you like that syntax, just like i do! you know what's a crazy new paradigm for someone? prolog. smalltalk. hell even haskell has some genuine differences from almost all other languages. basically every lisp is a totally normal dynamic language

clojure? they named a programming language after the mechanic girl from arknights???

Brazil’s Digital Banking Platform Nubank to Support Research Initiatives at Local Universities

Nubank (NYSE:NU), which claims to be one of the largest digital financial services platforms, announces NuFuturo, an ecosystem developed in partnership with Federal Universities in Brazil to accelerate careers in technology and foster innovation.

The initiative encourages the development of research “related to the fields of technology and finance in the academic environment and the impact they can have on society.”

Currently, NuFuturo is available in the Federal Universities of Campina Grande (UFCG) and Bahia (UFBA and IFBA), with projects that started in January this year.

After approximately 300 applications, “over 40 undergraduate and postgraduate students from Campina Grande (UFCG) and Salvador, Eunápolis, Vitória da Conquista, Feira de Santana, and Santo Amaro (UFBA/IFBA) were selected by specialists of the universities and are undergoing an intensive 18-month program to develop research projects and technological skills, based on systems and technologies used by Nubank, such as Clojure programming and data analysis methodologies.”

Sprongloxide is the obvious choice. If you're afraid of using pre 1.0 software then you haven't been programming in enough Clojure.

every software is like. your mission-critical app requires you to use the scrimble protocol to squeeb some snorble files for sprongle expressions. do you use:

libsnorble-2-dev, a C library that the author only distributes as source code and therefore must be compiled from source using CMake

Squeeb.js, which sort of has most of the features you want, but requires about a gigabyte of Node dependencies and has only been in development for eight months and has 4.7k open issues on Github

Squeeh.js, a typosquatting trojan that uses your GPU to mine crypto if you install it by mistake

Sprongloxide, a Rust crate beloved by its fanatical userbase, which has been in version 0.9.* for about four years, and is actually just a thin wrapper for libsnorble-2-dev

GNU Scrimble, a GPLv3-licensed command-line tool maintained by the Free Software Foundation, which has over a hundred different flags, and also comes with an integrated Lisp interpreter for scripting, and also a TUI-based Pong implementation as an "easter egg", and also supports CSV, XML, JSON, PDF, XLSX, and even HTML files, but does not actually come with support for squeebing snorble files for ideological reasons. it does have a boomeresque drawing of a grinning meerkat as its logo, though

Microsoft Scrimble Framework Core, a .NET library that has all the features you need and more, but costs $399 anually and comes with a proprietary licensing agreement that grants Microsoft the right to tattoo advertisements on the inside of your eyelids

snorblite, a full-featured Perl module which is entirely developed and maintained by a single guy who is completely insane and constantly makes blog posts about how much he hates the ATF and the "woke mind-virus", but everyone uses it because it has all the features you need and is distributed under the MIT license

Why Hire a Clojure Developer? Key Benefits of Using Clojure for Your Next Project

For a web or enterprise application, Clojure may not be the first language that springs to mind. However, it's a strong option for projects that demand simplicity, scalability, and great performance. Hiring Clojure engineers is becoming increasingly popular as more tech businesses look for code that is concurrent, tidy, and maintainable.

Clojure, which is based on the Java Virtual Machine (JVM), combines the flexibility and brevity of a contemporary Lisp with the strength and reliability of Java. Clojure might be just what you need if you are developing a new reactive application, data processing system, or backend. 

Modern Performance, Functional Reliability, and Simplicity in One Elegant Language

Clojure is a dynamic, functional language that prioritizes concurrency, simplicity, and immutability. Clojure, in contrast to conventional object-oriented languages, enables programmers to create reliable systems with less complexity and fewer side effects.

Hiring Clojure developers gives you access to a philosophy that prioritizes dependable logic, clear abstractions, and performance under pressure. Clojure's emphasis on pure functions and immutable data structures results in fewer errors and simpler testing.

Top Reasons to Use Clojure in Your Next Project

Immutable by default

Code that is immutable is more predictable. Writing functions that don't change state is encouraged by Clojure, which lowers problems and facilitates debugging and scaling applications.

Seamless Java interoperability

Clojure has complete access to Java libraries and operates on the JVM. This implies that you can write new logic in a more expressive language while utilizing pre-existing Java code.

Concurrency simplified

Concurrency was considered in the design of Clojure. Developers can construct concurrent code without the drawbacks of conventional multithreading by utilizing built-in features such as software transactional memory and agents.

REPL-Driven development

The REPL (Read-Eval-Print Loop) is a tool used by Clojure developers for interactive code writing and testing. Faster feedback loops and more fruitful development sessions are the outcomes of this.

These characteristics are strategic advantages for software organizations that prioritize agility and long-term maintainability.

Finding and Hiring the Right Developer

Hiring Clojure developers with practical experience and a solid foundation in functional programming is crucial because Clojure is a more specialized language than other languages.

They ought to feel at ease collaborating with:

The environment of JVM

Patterns of function and recursion

Frameworks for websites such as Luminus

Data libraries such as ClojureScript (for frontend) or core.async

Be ready to hire remote talent because many highly qualified Clojure professionals prefer working remotely. This broadens your search to include engineers from around the globe who are used to working asynchronously and are frequently involved in open-source groups.

Use an IT Staffing Agency to Simplify the Search

It can be challenging to locate Clojure talent on conventional job boards. Reaching pre-screened developers with the necessary experience might be facilitated by collaborating with an IT staffing agency. 

In addition to streamlining the employment process, agencies guarantee that technical proficiency, communication requirements, and cultural fit are fulfilled. This can significantly shorten time-to-hire and boost long-term placement success rates for expanding IT organizations.

Final Thoughts

Clojure is a strategic choice for contemporary, scalable, and maintainable applications; it’s not only a specialized language. Hiring experienced Clojure developers will result in agile development, cleaner code, and long-term dependability.

Clojure provides a sophisticated and practical answer to challenging problems for tech companies willing to look outside the box.
