Re: Reduce + merge-with error on lazy sequence of maps

There are a couple of errors in your code: 1. You have no initial value for the reduce, yet your output seems different to your input 2. prioritized-courses returns a seq, but merge-demand expects a map My guess is that you only get the error when you hit data in your input sequence with the same

Reduce + merge-with error on lazy sequence of maps

Hi all, I've had a case where reduce with merging operations throws errors on lazy sequences. I thought I should check in for insight before logging a bug. Maybe using maps as keys has something to do with it. too (I've since refactored) (reduce merge-student-demand everybody) Throws: Il

ANN: Suchwow 5.0.0

Suchwow is my grab-bag library of Clojure functions. 5.0.0 is a major version bump because I dropped support of Clojure 1.5. Otherwise, it adds a few new functions plus one potentially significant new namespace. In two jobs, I've wanted to slurp in tabular data (CSV or relational queries) an

I haven't, but definitely will look into macaroon for ideas. On Thursday, February 11, 2016 at 11:44:42 AM UTC-8, Ghadi Shayban wrote: > > Btw, ever looked at Macaroons? Apparently Google uses them internally. > > http://research.google.com/pubs/pub41892.html > http://hackingdistributed.com/2014

Re: [ANN] Ticket - an encrypted ticket/cookie library

Thanks! Yes I looked at JWE, but it just seemed a bit heavy for the need to only store a simple identifier. Interoperability isn't a concern, as tickets rarely if ever shared. I just wanted a simple self contained and easy to use way to package and retrieve identifiers with appropriately chosen

“compiling” stacktrace error

I'm learning Clojure, and I find difficult to understand *where* a specific compiler error happens: java.lang.ClassCastException: java.lang.Long cannot be cast to clojure.lang.IPersistentCollection, compiling:(fwpd/core.clj:100:1) Line 100 is just: (fib-seq3 5) So it says nothing, becau
