Avoid jQuery When Possible

jQuery does good jobs when you're dealing with browser compatibility. But we're living in an age that fewer and fewer people use old-school browsers such as IE <= 7. With the growing of DOM APIs in modern browsers (including IE 8), most functions that jQuery provides are built-in natively.

When targeting only modern browsers, it is better to avoid using jQuery's backward-compatible features. Instead, use the native DOM API, which will make your web page run much faster than you might think (native C / C++ implementaion v.s. JavaScript).

If you're making a web page for iOS (e.g. UIWebView), you should use native DOM APIs because mobile Safari is not that old-school web browser; it supports lots of native DOM APIs.

If you're making a Chrome Extension, you should always use native APIs, not only because Chrome has almost the latest DOM APIs available, but this can also avoid performance issue and unnecessary memory occupation (each jQuery-driven extension needs a separate

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

Performance of Flask, Tornado, GEvent, and their combinations

Wensheng Wang, 10/1/11

Source: http://blog.wensheng.org/2011/10/performance-of-flask-tornado-gevent-and.html

When choosing a web framework, I pretty much have eyes set on Tornado. But I heard good things about Flask and Gevent. So I tested the performance of each and combinations of the three. I chose something just a little more advanced than a "Hello World" program to write - one that use templates. Here are the codes:

1, Pure Flask (pure_flask.py)

def get_last_run(task_name):
    task = db.scheduled_tasks.find_one({'name': task_name})
    if task is None:
        last_run = time.time()
        # race condition possible, but this only happens at first run
        db.scheduled_tasks.update(
            {
                'name': task_name
            },
