Excellent Haskell Coders, Specialists for Hire in Ukraine

Haskell is standardized, exceptionally functional programming language with non-stringent semantics. The most important implementations are the Glasgow Haskell Compiler (GHC) compiler and the GHCJS compiler based on it, which compiles the JavaScript code into the script in JavaScript. Pugs are the implementation of the long-awaited Perl 6 programming language with the interpreter and compiler, GHC is often used as a test bench for advanced features of functional programming and optimizations. Darcs is a version control system that has several innovative features. Haskell is used by Linspire GNU / Linux with the aim to develop system utilities, at the same time xmonad is a window manager for the X Window System, written entirely in Haskell language. Haskell is a purely functional programming language. Functions have no side effects. This means that for the same values of the input parameters, the same results of the calculations will always be returned. Functional programming languages differ from imperative programming languages by the fact that the programmer should not determine the order of the calculation of functions. The developer should only describe the relationship between the data, and the translator alone determines the order of computing on the imperative computing device.

Questions and Answers related to Haskell Development

What do you use Haskell for at work?

“I work on supply chain optimization at Target, and our core system is written entirely in Haskell. I’m on the data science team that’s building the entire optimization system from scratch, replacing a complex legacy system running on an honest-to-goodness IBM mainframe. The effort is part of Target’s enterprise-wide supply chain transformation…”

What are some good strategies for writing Haskell under time pressure?

“It depends a bit on the length of the time frame and the type of coding. The main observation I make is that because Haskell’s type system is so strong and so expressive, the fastest way to understand what’s going on is to understand the types involved. The best way I’ve found to do this is to go through code very incrementally, and use compiler errors to guide your understanding of what’s working and not working with your approach…”

What are some use cases for which it would be beneficial to use Haskell in data science?

“Haskell is so much better as a language—more expressive, faster, safer. Haskell the language is great; Haskell the ecosystem is lacking. Haskell has not traditionally been used for data science so the library selection is limited. Integration with traditional “big data” tools is limited. While core pieces—like Spark bindings—exist, they are rarely as well-supported as in more popular data science languages. The same is true of statistical libraries and data visualization…”

How does garbage collection work in Haskell?

“GHC has a stop-the-world, parallel, generational, copying collector. It also has an in-place compaction collector for the old generation that can optionally be enabled. This paper describes it in more detail: Parallel Generational-Copying Garbage Collection with a Block-Structured Heap. There is also an experimental version of the collector that collects the young generation independently on each processor, although this version was never merged into the mainline GHC branch due to concerns about complexity and patchy performance…”
