On hiring Haskellers

Recently I noticed the number of the same two questions being asked again and again on different Haskell resources. The questions were “How to get a Haskell job” and “Why is it so hard to find Haskellers?” Although these two are coming from the opposite sides of the hiring process, the answer is really just one. There is a single reason, a single core problem that causes difficulties of hiring and being hired in the Haskell community, and we should clearly articulate this problem if we want to increase the Haskell adoption.

We all know that there are many people wishing to get a Haskell job. And a visible increase of Haskell jobs looks like there should be a high demand for Haskellers. The Haskell community has also grown like crazy past years. But still, why is it so difficult to hire and to be hired? Why can’t companies just hire any single person who demonstrates a deep knowledge of Haskell in blog posts, in chats, on forums, and in talks? And why do Haskell companies avoid hirin

Grouping results and removing unwanted ones

Here we want to scrape product name, price and rating from ebay product pages:

url = 'https://www.ebay.com/itm/Sony-PlayStation-4-PS4-Pro-1TB-4K-Console-Black/203084236670' 

wanted_list = ['Sony PlayStation 4 PS4 Pro 1TB 4K Console - Black', 'US $349.99', '4.8'] 

scraper.build(url, wanted_list)

At the beginning of 2030, I found this essay in my archives. From what I know today, I think it was very insightful at the moment of writing. And I feel it should be published because it can teach us, Rust developers, how to prevent that sad story from happening again.

What killed Haskell, could kill Rust, too

What killed Haskell, could kill Rust, too. Why would I even mention Haskell in this context? Well, Haskell and Rust are deeply related. Not because Rust is Haskell without HKTs. (Some of you know what that means, and the rest of you will wonder for a very long time). Much of the style of Rust is similar in many ways to the style of Haskell. In some sense Rust is a reincarnation of Haskell, with a little bit of C-ish like syntax, a very small amount.

Is Haskell dead?

Design patterns in Haskell

This is a list of patterns. I'm collecting this list with an idea to write a book similar to the GoF book.

My patterns:

Typed / Untyped pattern
Typed Avatar pattern (see Hydra and Node)
- Typed Options pattern (see EulerHS)
Control Structure pattern (see CLI control structure in Hydra and similar in Node)
