Get Started With the Yahoo HTTP Geocoder API

Since the major search engines have opened up their mapping tools to programmers, geocoding has become an essential step in the process of building many a mashup.

Geocoding is the process of converting human-readable place data — a city name, ZIP code, or address — to latitude and longitude points that can be easily plotted on a map.

Yahoo’s HTTP Geocoder API is easy to use, and its output is easy to incorporate into your applications. This article will describe its features and show some examples of how to access the results.

YouTube Tutorial Lesson 1 – The Player API

Dozens of video sharing sites may offer streaming video that plays back in higher quality than YouTube, but if you want eyeballs (and millions of them), then Google’s monstrously popular YouTube is the place to be.

For a long time, all you could do with YouTube as a web publisher was embed its hosted videos on your site. But thanks to a recent overhaul to the YouTube API, you can now do much more.

YouTube recently unveiled a new and improved Player API that allows developers to do things like re-skin the video player or create their own custom controls. In fact, if your scripting chops are up for it, you could build your own uploading interface for YouTube and then simultaneously post videos to YouTube and your site with one click of the mouse.

There are actually two different YouTube APIs — there’s the aforementioned Player API for skinning your embedded players and adding custom controls, plus the Data API for grabbing information about movies. Each API has a number of different functions.

We’re going to take a look at both the Data API and Player API on Webmonkey in this tutorial, but we’ll start with the Player API since it’s a little bit simpler to interact with.

RSS for Beginnners

Have you ever noticed those inviting orange buttons on some web pages, or spotted the odd link pitching an “RSS feed”? If you’ve ever clicked one out of curiosity, and then scratched your head at the unformatted gobbledygook in your web browser, you’ve seen an RSS file.


What is it really for, anyway?

Two things: RSS (Really Simple Syndication) and Atom are two specialized formats that create what’s commonly called a news feed, or just feed. A feed is an easy way for sites to share headlines and stories so that you can read them without having to visit two dozen different web pages everyday.

In other words, web builders use feeds to dish out fresh news and content from their websites and web surfers can use feed applications to collect custom-tailored selections of their favorite websites to be read at their leisure.

Use Camera RAW in Photoshop

This year, camera raw is the new black.

Everyone and their grandmother are shooting digital images. A lot of professional film photographers are leading the pack by taking the leap to the camera raw format. Even some mid-range, consumer-level digital cameras offer a raw format setting these days.

So what’s all the hype about? In terms of dimensions, digital photos shot in the camera raw format aren’t any larger than the highest JPEG setting on a camera, but the files themselves are over twice the size. What’s taking up all that space? The easiest way to explain it is to examine the differences between JPEG and raw.

When you take a picture that is saved in JPEG format, your camera is automatically making adjustments to your image and compressing the data down on the fly. Ever wonder what all those fancy settings on your camera really do? When you spin the little dial on your camera to access portrait, action shot, night scene or macro settings, you are unwittingly changing your ISO setting, picking a white point and applying certain exposure settings. Your camera then squishes all this information down into a compressed JPEG file. The original image that was captured by your camera’s sensors has been manipulated and adjusted; the original data ends up being lost forever in a jumble of settings and compression algorithms. The sad thing about this is that you have probably lost information within your image, especially in the highlight and shadow areas, and you’ll never get it back.

How Many Users Are on Your Site Right Now

Hello, readers. You seem to be sending me a lot of e-mail lately. Fortunately, my spam sorter takes care of most of it, but a substantial stream of questions and comments keeps pouring in, inscrutable character sets and all. I wish they were all as eloquent as this one:

Paul Loved your articel! I have a few question. 1 How to setup? thanks.. derek meatburp

…but lately there have been more than a couple asking how to implement what’s apparently a very desirable feature — a little display of how many users are currently accessing a site. Of course there are dozens of pre-packaged scripts to do this, but, just because I love you all, let’s take a walk through a couple of ways to build this sort of feature from scratch. We’ll use PHP, the popular and friendly scripting language, for our examples.
