Mongorito (License: MIT, npm: mongorito) by Vadim Demedes is a new MongoDB ODM with some interesting features: it has built-in caching using Memcacher (another module by the same author), and a small codebase by building on Mongolian. Automatic caching can even be set up, simply by setting a Memcached host using Mongorito.cache.

Mongorito has a model class, and the author gives examples in both JavaScript and CoffeeScript:

var Post = (function(){
  function Post() {
    Post.__super__.constructor.call(this, 'posts');
  }
  Post.prototype.validateTitle = function(callback) {
    if (!this.title) {
      callback(false);
    } else {
      callback(true);
    }
  }
})();
Post = Mongorito.bake(Post);
Post.find(function(err, posts){
  var length = posts.length;
  for (var i = 0; i < length; i++) {
    // posts[i] is an instance of the Post class
    posts[i].remove(function() {
    });
  }
});

The model definitions offer an alternative to Mongoose, and may appeal to those working on CoffeeScript-based projects:

class Post
  constructor: ->
    super 'posts'
Post = Mongorito.bake Post
post = new Post
post.title = 'About Mongorito'
post.save (err) ->
  # saved!

Despite being a new library, the author says the code is being used in production software, and he’s written some Mocha unit tests.

Memcacher

Memcacher (License: MIT, npm: memcacher) also by Vadim Demedes adds additional functionality to the Memcached module by Arnout Kazemier, in the form of tags and chainable methods:

Client
  .set('test-key', 'value', 2592000, ['some-tag'])
  .get('test-key', function(err, value) {
    // This callback intentionally left blank
  });

It’s a small but significant addition that should help those working with Memcached.

Restify

Restify (GitHub: mcavage / node-restify, License: MIT, npm: restify) by Mark Cavage is a new Express-inspired framework for building REST APIs. It includes both client and server support, so it’ll consume REST services as well as serve them.

Creating a basic server and setting up middleware looks just like Express:

var server = restify.createServer({
  name: 'myapp',
  version: '1.0.0'
});
server.listen(8080, function() {
  console.log('%s listening at %s', server.name, server.url);
});

It made me wonder if it’s Connect middleware compatible, because setting up routes looks the same as Express as well:

server.get('/echo/:name', function(req, res, next) {
  res.send(req.params);
  return next();
});

There are a healthy amount of unit tests (built with the tap module), detailed documentation, and a demo app.

Versionator

Versionator (GitHub: serby / versionator, License: New BSD, npm: versionator) by Paul Serby is Connect middleware for managing static asset caching. The basic middleware allows a global application version to be set, and adds an extra path to asset URLs so they’ll effectively be expired when the app version changes:

app.version = '0.1.0';
var basic = require('versionator').createBasic(app.version);
app.configure(function() {
  app.use(basic.middleware('v' + app.version))
    .use(express.static(__dirname + '/public', { maxAge: 2592000000 }));
});

Assuming a client-side script is at /js/app.js, it’ll now be available from /js/v0.1.0/app.js. There’s a Jade helper so the original URL can be referenced in templates.

There’s also ‘mapped’ middleware, which will only change resource locations when the files have changed.

FeedSub

FeedSub (License: MIT, npm: feedsub) by Roly Fentanes is an event-based feed downloader, that works the way a Node developer would expect:

var FeedSub = require('feedsub');
reader = new FeedSub('http://feeds.feedburner.com/dailyjs', {
  interval: 10 // check feed every 10 minutes
});
reader.on('item', function(item) {
  console.log('Got item!');
  console.dir(item);
});
reader.start();

It’ll also do a conditional GET based on the last modified headers:

// check headers for conditional get
if (res.headers['last-modified']) {
  self.getOpts['If-Modified-Since'] = res.headers['last-modified'];
}
if (res.headers.etag) {
  self.getOpts['If-None-Match'] = res.headers.etag;
}

To reproduce this:

• Create a folder on your Desktop named ‘test.’
• Create a file in that folder also named ‘test.’
• Move the file from the folder onto your Desktop.
• Click ‘Replace.’

Result: Both the folder and the file are deleted.

Do the same sequence, except choose ‘Keep Both Files.’ Same result.

[crarko adds: Okay, this one half worked when I tried it in 10.7.3. With ‘Replace,’ both file and folder were indeed deleted. I also tried it with other items remaining inside the folder, and in that case everything inside the folder was also deleted. A potential disaster.

In the ‘Keep Both Files’ case, the folder was untouched and the file was renamed to ‘test copy’ when I moved it and ‘test 2′ when I copied it.

Here are two quick and easy shortcuts to keep in mind for use in most text editing applications. Don’t bother with these in Word, they don’t apply. Try them in TextEdit instead.

The first you probably already know. It lets you open the font selection window. It’s Command+T.

The second you may not know, but it usually works in applications where the first one works. It’s Command+Shift+C and it opens the Mac Color Picker window. Two quick tips about this window:

1) If you click the magnifying glass icon, you can choose any color available on your Mac’s screen, and

2) you can drag a color from any point inside the rectangle near the top of the window into one of the squares at the bottom to store it there for future reference. Try dragging the bottom right corner of the window (and/or the right edge, if you’ …
