I find those posts more like Ads within the site. They all seem to be Y Combinator sponsored jobs. It's in no way different than how twitter, facebook and instagram post ads in between content.
For CSS architecture I thought SMACSS [https://smacss.com/] by Jonathan Snook has really good design patterns that have been proven to be good throughout his many projects.
I'm curious to know how the author managed to take a screenshot of the site? I know there were methods to actually recreate the DOM via some 3rd party library. Not sure if things have changed with HTML5 or others means of doing it.
I know certain websites like google buy domain names which can easily be misspelled and redirect them back to google.com. For typos like gogle.com, or adding extra 'o' gooogle.com
I agree this does look sweet, however this is not a replacement for alert. window.alert() is a blocking function, it prevents further code to be interpreted while the alert or prompt is open.
Well, it's also not a simple as you describe. You might have objects within the canvas that might also need to be resized, images, text, bg images, bounding borders, etc. All these things will need to be taken into consideration when being scaled or resized.
I was eager to learn about HTML5 Canvas, so I created a small project and learned a great deal while developing a lightweight canvas library, which hopefully others will also find helpful. https://github.com/vladakilov/imagine
I've been working on something similar, it's a lightweight HTML5 Canvas library, easily add/remove objects on the canvas. It also has event handling for the objects. http://vladakilov.github.io/imagine/
For those of you who want a more developer friendly way of working with sprites, I would like to introduce you to Compass (http://compass-style.org/help/tutorials/spriting/) Spriting. Along with using SASS, it will make creating and maintaining sprites a lot easier.
I'll agree with many of the guidelines, but some are just personal taste. For instance, I like to indent my JS with 4 spaces and so does Douglas Crockford (http://javascript.crockford.com/code.html)
I was looking for something like this a while back and found a useful firefox plugin called Poster (https://addons.mozilla.org/en-us/firefox/addon/poster/). It's useful for testing a RESTful api without creating any front-end code to handle the requests. Or anything you can do with cURL just simpler.
Seems like a good app to get beginners started with learning to code. What stack is this built on? What language are you teaching with, is it javascript?
It's not just for the chrome browser because it's built on HTML5 and JavaScript and can be used on any modern browser. I'm currently using firefox to view this "app" which is just a regular site, well it's actually a very clean & impressive design and great UI features. Some of the so-called apps in the chrome store are merely bookmarked links that go directly to the page, for instance the gmail "app". I'm having a really hard time to accept these as "apps"
