The `paused` flag is stored on LocalCollection, but two places in minimongo looked for it on the `query` object (which represents an active observeChanges call). In both cases, the bug had no correctness impact but could have a performance impact. Bug 1: `_recomputeResults` (used to calculate changes to skip and limit queries) tried to avoid calculating the diff if the collection had been paused (by pauseObservers as part of latency compensation), but it looked for the `paused` flag in the wrong place and always ran the diff. This didn't have an effect on correctness (because the wrapped callbacks on `query` are no-ops when `paused` is set) but did waste time on unnecessary diffs. Bug 2: In `update`, we tried to avoid saving original results for skip/limit queries if the collection was paused, because we don't actually run the diff for paused queries. (Well, except for the fact that Bug 1 made us run the diffs anyway...) But since we checked `query.paused` instead of `self.paused`, we wasted time cloning the results even if we were paused.

Meteor
Meteor is an ultra-simple environment for building modern web applications.
With Meteor you write apps:
- in pure JavaScript
- that send data over the wire, rather than HTML
- using your choice of popular open-source libraries
Documentation is available at http://docs.meteor.com/
Quick Start
Install Meteor:
curl https://install.meteor.com | /bin/sh
Create a project:
meteor create try-meteor
Run it:
cd try-meteor
meteor
Deploy it to the world, for free:
meteor deploy try-meteor.meteor.com
Slow Start (for developers)
If you want to run on the bleeding edge, or help develop Meteor, you can run Meteor directly from a git checkout.
git clone git://github.com/meteor/meteor.git
cd meteor
If you're the sort of person who likes to build everything from scratch, you can build all the Meteor dependencies (node.js, npm, mongodb, etc) with the provided script. This requires git, a C and C++ compiler, autotools, and scons. If you do not run this script, Meteor will automatically download pre-compiled binaries when you first run it.
# OPTIONAL
./scripts/generate-dev-bundle.sh
Now you can run meteor directly from the checkout (if you did not build the dependency bundle above, this will take a few moments to download a pre-build version).
./meteor --help
From your checkout, you can read the docs locally. The /docs directory is a
meteor application, so simply change into the /docs directory and launch
the app:
cd docs/
../meteor
You'll then be able to read the docs locally in your browser at
http://localhost:3000/.
Note that if you run Meteor from a git checkout, you cannot pin apps to specific
Meteor releases or run using different Meteor releases using --release.
Uninstalling Meteor
Aside from a short launcher shell script, Meteor installs itself inside your home directory. To uninstall Meteor, run:
rm -rf ~/.meteor/
sudo rm /usr/local/bin/meteor
