Hi!
I have some frustration with current official jdbc wrapper for clojure and
I have worked in one alternative mainly because of:
- Lack of documentation.
- Philosophical differences of how things should be done.

Hi Marcin,
Why did you choose to group LESS compilations, CoffeeScript minification,
caching and resource minification in one middleware function? Why not have
a separate middleware function for each?
For example, instead of:
(compiled-assets-loader
precompiled
:lesscss-list
When i run this:
(clojure.java.shell/sh chat -Vs ' ' 'ATi' 'OK' ' '
/dev/ttyUSB0 /dev/ttyUSB0)
I get this:
{:exit 2, :out , :err Can't get terminal parameters: Inappropriate ioctl
for device\n}
When i run the command directly on the shell, it works. What is causing the
error? any options i
Well, I made sure you can do it:). I created the grouped middleware
functions for convenience's sake and I intend to add more.
Something like that will work:
(let [loader (resource-loader /precompiled)]
(-

Good job, Andrey. It's important
Clojure = 1.5 was built with Java 1.5. Clojure 1.6 is built with Java 1.6.
Neither uses anything special from Java 1.7 or 1.8. The changes are just making
sure that Clojure will work with Java 1.8.

Cornet works on lower layer and does not use ring-spec or HTTP. All the
functions and middleware in Cornet take path as String and return
java.net.URL (either file:/... or jar:file:/) [as a side note: at some
point I want it to be able to return data as InputStream or String instead
of urls. ]
Hi all,
I've just published the first working version of a Ring middleware that
some of you might find useful. It's designed for web apps where, if
you're overloaded, it's better to serve some requests quickly and fail
the others than to try and serve all the requests and do it slowly. (My

Doesn't this approach risk unnecessary repetition?
I am not sure if I catch your drift... What I wanted to have is a direct
replacement for clojure.java.io/resource function - so if at some layer you
come down to using this function, you can just replace it with cornet
generated handler -
I can think of very few web apps where this would be a desirable approach.
A user getting a spurious error in response to a URL that they *know* is
valid is just going to hammer on the reload button until they get a
correct response from the server. So the server will end up even more
congested

It may be useful for certain web services. If the server gets overloaded by
a temporary spike, the clients could pick a random sleep time before trying
again.

I've use many services within apps that are json or xml results served over
HTTP. This is a common way to integrate third party data or functionality
into an app (especailly webapps or mobile apps).

I guess that could be considered as part of the deployment process, done

Hi,
I'm trying to understand the design of Clojure's collections and one
thing that I find odd is the return of functions operating on sequences.
Like for instance a call such as this will return a lazy-seq and not a
vector:
(drop 2 [1 2 3 4])
The reason why I find it odd is that

That sounds like picking a random sleep time before trying again to me :-)

I don't know if it is idiomatic, but it certainly looks like a good way to
achieve the desired effect.
If you chained together calls to several functions like your example
only-evens, it would not be lazy, and it would build up a separate instance
of collections of the original type at each step
d'oh! Answering my own question: Just compose the unify functions a la
(unify (unify a v1 (:v1 r) v2 (:v2 r))
I have a feeling there is a library function/macro that would make this
less messy but I can't find it from the cheatsheet.

This efficiency is why built-in functions to map, filter, etc. vectors to

Andrey, this looks interesting. It seems to be based on a really old
version of clojure.java.jdbc, though. Is there a reason for this? Since it
is a fork, it seems like it would be best to base it on a recent version,
to aid those who may want to try switching to it. Also, does it require JDK
FWIW, Netflix uses a sorta similar approach but the overload detection
lives on the client-side since different clients may have varying
definitions of slow, may want finer grained control of fallback behavior,
