I'm a CS major with more interests than time or energy and an unhealthy addiction to parenthesis. I hack clojure and C for fun and dream of a saner operating system and desktop environment.

Author here.

Oh. HN frontpage. That's cool I guess.

Well I have plans for today, so I'm sorry that I won't be sitting here defending my article.

However if you hit me up on twitter at the link at the bottom or email me at my listed email address I'd be more than happy to respond and debate this piece in due time.

Cheers! Reid

Author here. Holy cow. Thanks for all the kind words guys! I'm primarily a back end dev interested in hardware, compilers and operating systems. As a long time HN reader I can't begin to express how amazing it is that a my first "real" web service which I started less than a week ago made the front page.

I hope that for those Clojure users among you Grimoire proves a useful resource and I welcome any feedback or other commentary you may have on the site and its usability. Stay tuned, there's plenty more in the works from me and I'm reading the feedback with interest.

Author here. After maintaining a blog built around a "real" CMS, and a "real" CMS that I built myself, I'll say that my existing blog is built atop Jekyll and Git, the same stack I chose for Grimoire. It's simply the most basic thing that could possibly work, and it doesn't demand that I run a JVM on my inexpensive DigitalOcean instance. For all that I enjoy using Clojure, a "real" Ring server with a "real" database backend simply doesn't add anything to this project beyond complicating it further. As such I don't expect that a database rewrite of Grimoire is on the cards for some time to come.

To "how you build such a site in Clojure" the answer is that the entire Clojure ecosystem shies away from monolithic web frameworks and prepackaged solutions ala rails. Instead, Clojure libraries tend to pick a single feature or some small set of fetures, cover them well, expose a simple API and make composition trivial rather than trying to solve all possible problems.

Dash integration... Dash only makese sense for languages for which the documentation isn't trivially introspected such as Java. Clojure has the clojure.repl library (http://grimoire.arrdem.com/1.6.0/clojure.repl/) which is designed to solve this problem by exposing Clojure documentation to users in their interactive development (REPL) sessions. As I explain at some length in the Grimoire announcement post (http://arrdem.com/2014/07/12/of_mages_and_grimoires/) Grimoire seeks to fill a fumdimentally different niche than Dash. Clojure already has docs, and those docs are already handy for users aware of clojure.repl. Grimoire seeks to solve the problem of documenting the various ins and outs of the standard library which do _not_ appear in the official Clojure docs and which are currently spread out across any number of other low PageRank score community sites.

Author here. I'm definitely aware that there are many pitfalls to Clojure than just the standard library docs. There's an open issue for adding a syntax guide and a macro guide, I'd be delighted to add a destructuring guide.

Author here: It's funny that you say this because as of right now there is only one example on Grimoire that isn't on Clojuredocs :P

I'm sure that adding a small disk with the source code to the warhead would be an acceptable and valued solution.

When the risk of of obtaining content by illegal means is not outweighed by the cost of doing so by legal means. If I can pay USD 1 or Ɖ1500 or some other small amount to watch a movie not listed on Netflix instantly I would gladly do so. The risk of getting a "friendly reminder" from the RIAA or some other entity that $UNIVERSITY is required to disclose who I am and that I've been a bad boy completely outweighs such a low cost. However if it costs me $5 or $10 or I run Linux (which I do) and can't even use any of the legal services then it becomes worth my time, effort and risk to find three proxy services which I halfway trust and run a Torrent client over some combination of them.

Correct, however if this "exact runtime bound" is what you are going for, then please use the correct notation. T(N) = 2N would be legitimate, as would \Theta(N) = 2N. Saying that O(F(N)) = 2N is misleading because the definition of the big-o notation explicitly discards all constant factors and constant annends.

Totally agreed, unfortuantely however this introduces significant constraints in the parent/child/sibling insertion and navigation model.

No. That would defeat the entire user model, which is purpsoefully derived from Bitcoin's anonymity structure.

"designed two processors". No. We had working A0 production runs of two chips, with a the A0 of the third generation in the post when we closed. Leaner? Not really. Sales team was three people more the executives, everyone else was engineering. Meaner? Who on earth pulls off two working A0 runs?
