I hope this is the right place to ask this question. I have a Haskell app
running on Cedar, and I am having some trouble with logging. When I print
to stdout and run my app locally, I can see the output; but it does not
appear in `heroku logs`. In fact, `heroku logs --source app` is quite
empty
I get the same problem and I believe it is because the Heroku/Eclipse

Hi all,
I've packaged up a new gem for serving the .gz files that are created by
the Rail's asset precompiler.

Usually these gzipped files are served by something like nginx. Since nginx
isn't available on Cedar, you can use this gem inste

What problem are you trying to solve? If you're worried about slow clients,
using a webserver like thin should be sufficient.

NewRelic can do some of this with End User Monitoring. Google Analytics is a

My recommendation: switch to bamboo-ree-1.8.7 and specify all your gems in
your .gems file, including rails (and pg), regardless of which version of
Rails you're using. This should solve the Rails dependency issues since
bamboo doesn't rely on installed gems. While installed gems seemed

I don't believe implicit casting is possible in any version of Postgres -
Postgres doesn't try to act like MySQL, it tries to be ANSI SQL compliant
(it's like Internet Explorer versus Firefox).

In Postgres, you can only do string searches on string columns. Your options
are thusly:
1. Stop doing this. Do you really want to be searching an integer like a
string?
2. Convert ID to a string column. You shouldn't do this either, unless "id"
was just an example.
3. Tell Postgres to cast it to
You can add MX records to the Zerigo DNS or, of course, your own DNS host. I
