Web Application Development with Clojure – Part 3 (via @hisaitami) — This one covers getting data from the database and rendering via templates.
Now available online @ O’Reilly: the *final* draft of Clojure Programming by @cemerick, @briancarper, & @cgrand (via @ClojureBook) — 600+ pages of pure and unadulterated Clojure, all in one package!
My new blog is up! First post: Monads are design patterns for DSL’s. (via @jimduey) — This post explains monads by using them in building a DSL.
clj (0.0.1): Like json, but with clojure sexps. (via @rubygems) — Oooo, now you can exchange cloure sexps back and forth with Ruby!
Good blog posting – Java and Clojure – How data structures influence language usage (via @staypufd) — You might have experienced this too, the ease in which you can work with complex data structures in Clojure changes the way you code, more so if you come from a low-level imperative language.

Emblogginated: Clojure Conj 2011 – Learning more pt.1 (via @fogus) — Yesterday Clojure/Conj released the first videos of the last conference. This post augments those talks by adding pointers to possible follow-up topics.
Flog: “Some thoughts about classes after 18 months of Clojure” (via @jasonrudolph) — This is a 30 min presentation about how to rethink OO in Ruby by taking the perspective of Clojure and separating data, typing and methods.
Bunch of people in #clojure are digging @trptcolin’s reply (alternative REPL frontend)…coming soon to leiningen? (via @cemerick) — Cool, so now we have too of such initiatives going on. Definitely the barebones REPL frontend needed some love!

and we are live! EuroClojure 2012 “the first 2-day, full-blown conference in Europe for the Clojure community.” (via @EuroClojure) — Niiiice! Did you want to go to London but didn’t have a valid excuse to do so? Now you have one: two days of Clojure talks, with a very interesting talk selection method. Now, where can I find a cheap flight?
First Conj 2011 Videos Available (via @clojure_conj) — Speaking of Conferences. If you were to slow snagging a ticket for last year’s Clojure/conj, you can pretend you did go by watching these very well produced videos of the talks. This is the first batch, more to come.
The first public demo of the @LonoCloud OS implementing a multi-cloud federated mobile health application in #Clojure (via @0×1B) — Flashy! Doesn’t show any Clojure code though…

A sweet blog on the challenges of developing games with Clojure (via @swannodette) — Not many people think of Clojure when deciding to write a computer game, but some do, and this article summarizes where Clojure falls short in as a gaming platform.
Solving Pell’s equations with the Chakravala method and Clojure (via @hnfirehose) — Apparently solving some of the Project Euler problems is not a trivial task, and in this case it needed implementing an algorithm that is over 1000 years old. Older than LISP! Bonus: more clojure solutions for Project Euler problems.
Just pushed the Swank Clojure 1.4.0 release with a stable CDT debugger and improved stack traces. Thanks to @tavisrudd and @georgejahad (via @technomancy) — What this means is that Emacs gains an even better debugger if you’re using swank-clojure (you probably are).
clojure and leiningen – using a git repository as dependency (via @tobyhede) — Now that’s one little gem hidden in the goldmine that ClojureScript One is: declare git repos (and even the actual commit) as project dependencies. Why use a Maven repo when you can go straight to the source?!!?
Announcing the new Clojure/West “Friend of Attendee” program! You could get a discount or refund! (via @ClojureWest) — That’s right, refer a friend to Clojure/West (or any other human I believe) and get a discount or a refund if you have already paid (as long as your ‘friend’ buys a ticket too)
- So far the company with the most developers attending Clojure/West is… Apple. Surprised? (via @ClojureWest) — I am not going to lie: yes, surprised.
“The Reasoned Scheduler” (via @cgrand) — “tl;dr How I realized that core.logic (or miniKanren) is essentially a scheduler.”

[InfoQ]Presentation: Event-Driven Programming in Clojure (via @skrlatica) — This is the video of Zach Tellman’s excellent talk on working asynchronously in Clojure.
Creating a custom map type in Clojure (via @david_mcneil) — This is very interesting. This gist shows you how you can build typed maps in clojure, including building them from literals (in Clojure 1.3).
Wrote a bit about project automation and the poison of nondeterminism in Leiningen (via @technomancy) — This is an excellent write-up about what makes build automation sometimes unreliable, listing the worst offender parts of this automations, the reason why they make the process unreliable and ways to solve this issue in leiningen.
Clojure sparks LISP usage in the enterprise. Am I right? Wrong? Comments, please (via @JWVerity) — It is interesting to see how Clojure is permeating the Enterprise, to the point that IT magazines are picking up the trend. This article is for IT Software Community, and it explains the many ways Clojure is used in Enterprise settings.

Finite State Machines in Clojure core.logic (via @P_E) — Title says it all. But beware, it’s not preambled with an introduction to core.logic!
Use CouchDB like a Clojure collection: Clutch 0.3.1 SNAPSHOTs now available (via @cemerick) — This was talked about some time ago, so now it seems there is an implementation: when using these collections, you’ll be interacting with CouchDB (Search for “Experimental” in the linked page). Some of the examples in the github README are hard to read due to github not properly rendering ascii code blocks, so use this as a guideline (the REPL demo part).
New version of ClojureScript One is out. http://clojurescriptone.com No more scripts! Everything works through Leiningen. (via @brentonashworth) — No more scripts is a good thing.

Searching for functions you can’t quite remember w/ #clojure’s apropos (via @sritchie09) — This is one of those very useful but often forgotten functions in clojure. Now, if someone could come up with a similar function that knows what I mean and not what I say…
Done! @ClojureBook is complete, and is now “in production”. Safari Rough Cuts update coming soon, action on clojurebook.com &c. :-D (via @cemerick) — Congrats!!!

outlet a new lisp like language compiles to js, inspired by scheme and #clojure (via @wmacgyver) — It’s borrowing the data structure literals from Clojure, amongst other things. WIP. Worth checking it out.
Jars for ClojureScript on Maven Central!??!?! Nice way to start the weekend, no? (via @disclojure) — Oh yeah. That is a gigantic step for all those developing applications using ClojureScript. This makes the building process saner (did I just put ’sane’ and ‘build process’ in the same sentence?!)
A #clojure macro I wrote recently can be expressed much more elegantly as a clojure monad (via @sritchie09) — A nice example of the usefulness of Monads.
A roughly three-hour screencast of me building http://typkov.stevelosh.com with Clojure/Noir/Vim (via @stevelosh) — Needless to say, I watched the whole movie! I think we’re a tad far from the “Build a website in 5 minutes” demos that the Rails guys used to do…

Want a better Clojure REPL? Check out IClojure, inspired by IPython (via @offbytwo) — If you’re using the command line REPL in Clojure, you might find this project very exciting. Tab completion, better Ctr-C handling and other goodies. About time somebody took a look at this area if you ask me!
Posted the Clojure/West schedule in a grid (via @ClojureWest) — Don’t forget about the training options!
Web Application Development with Clojure – Part 2 (via @condotti) — This is a very detailed tutorial on writing webapps with Clojure and the latest and greatest stack.
Porting effort for Clojure contrib libs (to #clojureclr) (via @dmiller7218) — This post announces an effort to port the most ‘popular’ contrib libraries to ClojureCLR. The comments section is full of good stuff, including news about ClojureVS, a MS Visual Studio plugin for Clojure.

ClojureScript One screencast (@stuartsierra) — Ooooo! ClojureScript One now comes with a nifty screencast! Look’s like we’ve come a long way in terms of tooling for ClojureScript, which is a very very good thing in my book. Be careful though, since watching this video may result in sleepless nights of coding…
Using Hadoop and HBase with Clojure (via @hnfirehose) — This tweet has a high buzzword/word ratio, and for a good reason: it explains how to build a log analyzer that can quickly deal with gigabytes of logs, all in Clojure.

Clojure on CloudFoundry (via @Sunng) — “As you may know, CloudFoundry is an opensource PaaS backed by VMWare. Java, Ruby and Nodejs are officially supported. As a JVM language, clojure is born to be also available on this platform, although it’s not listed.” Clojure everywhere!
Clojure/West early bird registration ends in 1 week (via @puredanger) — Get on it! Take a look at the scheduled talks, in case you’re not yet convinced.
Netz – Clojure Neural Network Library. (via @nickewing) — It’s not enough that Rich Hickey is asking all of us to think. It’s time to make computers think too!
What makes #clojure different? (via @chlalanne) — I know, I know, preaching to the choir. But maybe forward it to those friends looking for a language to broaden their minds?
#clojure 1.4 alpha 4 released. (pmbauer) — Good time to remind everyone that Clojure keeps chugging along.
wow, clojure is tiny compared to jruby and jython! (via @killerswan) — Just to clarify, this tweet refers to the size of the language implementation, not any other attribute. The tl;dr version? Clojure has 50,095 loc, and JRuby 196,762

Great interview with @samaaron about Overtone (via @sofra) — I think we should proclaim Sam Aaron Clojure’s musician in residence, yes? I am assuming he’ll be putting a big show for Clojure/West too! ;)
Interesting infographic based on #code2011 Twitter meme. #clojure has a decent showing. (via @seancorfield) — Yes, and surprisingly, not one single complaint about parentheses!
Using Clojure’s core.logic with custom data structures (via @sznyelveszet) — One of the most interesting part of this article is what doesn’t appear in title: with custom data structures means, with custom *Java* data structures. Now this is 10 times more awesome, amirite?

Clojure/West early bird registration $450 ends January 20th (via @ClojureWest) — Today is Clojure/West day, since the speakers-to-be have been notified about the acceptance (or refusal) of their abstracts, so twitter seemed full of happy clojurians (the unhappy ones must have kept their ire private). Now it is a good time to register before the conference gets more expensive.
Where my Clojure plays with protocols, multimethods and the SICP (via @yueliufeeds) — Implementing the OO ideas in SICP using Protocols and then using those objects via higher-order functions.
Intro to Clojure-clr: Creating a UI with Windows.Forms. (via @rippinrobr) — Quite detailed article on how to build GUIs with Clojure-clr and .NET. Keep them coming, the CLR needs some Clojure love!
ClojureScript One (via @fogus) — From the left field comes this awesome project set to make ClojureScript, in one fell swoop, much more approachable. A set of tools, libraries, working code and comprehensive wiki. You should be all set to start coding. Go check it out!

Creating a Clojure CLI’s (via @capotribu) — A very approachable article about writing Command Line applications in Clojure.
Working on a CouchDB type for #Clojure (via @cemeric) — This is very interesting: trying to make working with CouchDB documents similar to working with Clojure maps.
multimethod.js – a Clojure-inspired multimethod library for JavaScript (via @hnfirehose) — At this point, shouldn’t you just move on to ClojureScript? In any case, more evidence of how ductile JavaScript is: Scheme in Java disguise.
awesome use of core.logic by @holy_chao (via @swannodette) — And an interesting project in itself: “Monotony is a solution to the problem of how to schedule things in a way that humans find intuitive.”
What’s List Comprehension and Why is It Harmful? (via @xah_lee) — They are deemed harmful?!?!? If so, then some of my codes should be considered weapons of mass destruction. The article makes a good point, which is that functional languages already have the primitives to build the functionality.
The reason why I chose to use Java instead of Scala or Clojure. Why Use Inferior Tools (via @orfjackal) — See, the main threat to Clojure adoption is not that developers will chose to move to another JVM language, but that they’ll decide to stay in Java. Tooling matters, much.
Writing Elegant Clojure Code Using Higher-Order Functions (via @planetclojure) — If you are new to Clojure and you wonder why some people are so ga-ga over Higher Order Functions (HOFs) then this is for you. And if you’re seasoned, it won’t hurt to read it, just in case. If you come from Haskell and the likes, don’t bother. An introduction to the use of HOFs in Clojure.
I’ve prettied up swank-clojure stack traces a LOT. Here’s a taste of what they look like now (via @dmansen) — Ooooo! Pretty!!!!
Not-So-Private #Clojure Functions Short and to the point! That’s the kind of article I like the most. (via @jaceklaskowski) — How to get around the ‘private’ restriction in defn- functions (for testing, of course!)
Nice post by @schleyfox on testing Storm topologies in Clojure (via @nathanmarz) — In Storm (the real time, fault-tolerant, distributed computation thingie) you can describe the topology of the setup via Clojure. This article is about testing those topologies. Can you count the level of abstractions over basic coding? Yeah, me neither.

Phew! That was a long post. Keep it up guys!

/me adds “mastering Clojure” to it’s todo list…(via @ToJans) — “The Sapir-Whorf hypothesis tells us that our view of the world is strongly affected by the languages we use.” With this concept, Bob Martin theorizes that we will (have to) move on from programming languages that are closely tied to computers to more abstract languages–like Clojure: “It’s a different mode of expression, and it makes you see concepts that are difficult, if not impossible, to conceive of in Java, or C”. Interesting and thought provoking read. Must.
Emblogginated “(take 6 carin-meier)” (via @fogus) — Interview with Carin Meier, both a rubyist and a clojurian and quite involved with the community, she offers some insights on the differences and similarities of both communities, and a new programming paradigm: “coding moccasins”
This is the #Clojure documentation I’ve always wanted #typed-clojure (via @ambrosebs) — As @fogus said: “It’s not that Clojure programmers denounced static typing. It’s just that no one had written the library yet.”. Indeed. This is a draft of what an initial typing system would look for Clojure.

Converted Common Lisp and Java code for my SAAS to 100% Clojure. Some info: (via @mark_l_watson) — Known author Mark Watson decided to ditch a Common Lisp + Java implementation of a NLP+AI+SemWeb service and rewrite it instead in Clojure. I here encourage (demand?) the author to blog about the experience.
Ring 1.0.0 Released (via @planetclojure) — This is bigger than when GMail went out of beta. Congrats Mark and James!
A Leiningen dependency-tree “hello world” (via @cemerick) — A lot of changes are going into Leiningen 2.0 these days, furious development it seems. What we can see here is the kernel of a feature to see all the dependency tree of a project from Leiningen itself without having to drop to Maven (ugh!), although this code is using aether, which is part of Maven.
Rich Hickey will be speaking at Clojure/West (via @ClojureWest) — Very very nice!
introducing knockbox (via @reiddraper) — “It’s a library meant to make dealing with conflict-resolution in eventually-consistent databases easier. If you’re not familiar with eventual-consistency, I’d suggest this article by Amazon CTO Werner Vogels [...] Distributed databases like Riak let you trade consistency for availability.” This is actually one of the main pain points of highly scalable databases, no?

Just pushed Clementine gem. This is for ClojureScript for Rails asset pipeline. Though, preliminary implementation so far (via @yokolet) — It would seem like this will only work for JRuby, and it allows to use cljs as an asset in Rails.

Want to learn Clojure, online? (via @cfbloggers) — If you want to properly learn Clojure, Amit Rathore, the author of Clojure in Action is running a 6-week online course at CodeLesson.
It’s impressive to see how the @Clojure community is fighting NIH. And doing so with consideration and rigor. (via @soyrochus) — The tweet doesn’t give away too much, but this is about Cake and Leiningen merging into Leiningen 2.0. So you get to have your Cake and eat it too!
Emacs configuration for Clojure development (via @FlorianScheel) — Nice to see how easy has it gotten to get Emacs working with Clojure these days. In my days we had to code some elisp!
Clojure/West Overview (12/1/11) – slides from @puredanger from last night’s Bay Area #Clojure meetup (via @seancorfield) — The conference is shaping pretty nicely and some info about keynotes and workshops is already published. (disclosure: I’ll be helping with the logistics — I sooooo wanted this to conference to happen — and also teaching in the Pallet workshop)
I have this working now: A single #Clojure test case running in the browser and on the server. (via @brentonashworth) — I wonder if this kind of experiment will end up bending the universe and providing some time travel opportunities… Some laws should not be broken, no?

Clojure & Complexity (via @planet_lisp) — Yesterday it was Scala that got a private-turned-public beating, and today it’s Clojure-bashing day, it seems. A decent summary would be “Clojure is not Common Lisp” and “we don’t need Clojure, we can do everything in Common Lisp”.
Hey I made a thing to make configuration of functions easier, try messing around with it (via @holy_chao) — Fidjet is the name of the project, and “If you write a core API where functions accept some config parameter as their first argument, you can then create a parallel namespace where those same functions can be used in a with-config block.”

Relative growth: functional languages are growing more than anything! #FP is the future (via @diego_pacheco) — We’ve seen this graph before. Clojure keeps going strong in adoption (job openings), so are Scala and Erlang.
Pattern matching in #clojure core.logic no longer needs ? prefix to introduce variables. Even more declarative, sweet! (via @ambrosebs) — It looks like all the variables named ?something won’t be needed anymore in core.logic.
Just blogged “Scheme as an embedded DSL in Clojure” at http://martinsprogrammingblog.blogspot.com/ (via @ martintrojer) — Just in case you came to Clojure from Scheme, now you can get both, together.
[ANN] Avout: Distributed State in Clojure (via @liebke) — Distributed STM, in clojure, with distributed versions of Atom and Ref. Asynchronous communication across systems clojure-style.
Yammer moving off of Scala… maybe an opportunity for some #clojure? (via @mi_camp) — This was an email that was supposed to be private but that somehow got leaked, in which one of the engineers at Yammer explains to both the CEO of TypeSafe, and Martin Odersky the creator of Scala, the reasons why Yammer is back to Java after years of using Scala. A good exercise is to carefully read this email, understand the pains the engineer is referring to, and then think about where Clojure is inflicting similar pains. And no, it doesn’t look like they’re moving to Clojure either.
