Resolve also has a premium Studio offering with some features that are particularly appealing to professional users. I assume that helps cover some of their costs.

I got one so that I could make copies of my apartment keyfob; I live alone and having a spare keycard that goes inside my phone case has saved me from locking myself out of my building multiple times. For me it's already paid for itself by ensuring my peace of mind. I've also used it to copy my gym tag (NFC), my parents' apartment keyfob (also NFC surprisingly), and multiple office access cards.

This article doesn't touch on what I consider to be the central feature of Haskell: it is lazily (more precisely non-strictly) evaluated. A lot of the other aspects of it, such as monadic IO, follow from that decision.

Have you worked with Nix much?

Why not `git clone --bare`?

I hope there's at least one chapter on compact data structures!

I wrote about these too: https://vaibhavsagar.com/blog/2018/07/29/hamts-from-scratch/! Unfortunately it's in Haskell which probably makes it less approachable than it would be otherwise.

I personally use Vim, but Emacs alone is IMO the strongest counterexample to your claim about Lisp interpreters (followed by all the programs scriptable with Guile).

I also have my own implementation of packfiles [1], which I implemented as part of a toy Git implementation in Haskell [2]. I personally found the packfile format underdocumented, e.g. the official reference for the packfile generation strategy is an IRC transcript [3].

What if Haskell is my favourite language?

This is why I do all of mine in Haskell.

New comment by vaibhavsagar in "Understanding Bloom filters by building one"

vaibhavsagar — Sun, 29 May 2022 04:25:33 +0000

Doing a hashmap lookup is already very much like using a bloom filter: for any addressing scheme, if an element exists at a particular location, then either the key exists or it's a false positive. If no element exists, then there's no way the key exists. Adding an extra bloom filter would then come down to trading off space usage against a different probability of false positives, in addition to an extra lookup, and I think one would have to contrive an extremely unlikely scenario for it to make sense.

New comment by vaibhavsagar in "Ask HN: Why would anyone choose Haskell to develop applications?"

vaibhavsagar — Sun, 06 Mar 2022 23:39:55 +0000

At my last job, we had a Python codebase that had grown large and unwieldy. We wanted a language with stronger compile-time guarantees and better concurrency support. After evaluating several options the team at the time settled on Haskell and it's still used on all our kiosks to perform tasks including interfacing with the credit card reader: https://www.youtube.com/watch?v=O-z8hDXIQSg

New comment by vaibhavsagar in "Ask HN: Anyone working remotely for a US company internationally?"

vaibhavsagar — Fri, 22 Oct 2021 17:51:06 +0000

Yup, I'm doing this. I was living in the US when I interviewed in Feb 2020 but as an Australian citizen on an E-3 visa I had to leave the country to get a new one and then the pandemic happened. So far my employer has been happy to have me work remotely but the timezone offset has been pretty brutal and I'm only doing this because I hope to move back at some point early next year.
