From small-business support company Grasshopper comes Chargify, a billing and subscription system for web 2.0 and SaaS companies that eliminates the need to build bespoke applications.

Their RESTful API and hosted payment solution permit simple integration into any website, allowing businesses to charge customers on a recurring basis, manage subscriptions, achieve PCI compliance, and gain real-time business intelligence from their billing.

In addition to processing one-time and recurring transactions, Chargify handles free trial periods, promotions, refunds, receipts, and reminders.

Also, their pay-as-you-grow pricing seems ideal for small businesses and startups. The first 50 customers are free and range up to $1,500 for 15,000 customers or $2,500 for an unlimited number of customers. Chargify does not charge individual transaction fees.

Take a look at this demo video from the Chargify team:

The API accepts method calls via HTTP and returns responses as JSON or XML, allowing companies to keep the customer purchase flow on their own sites and authenticate users while passing the billing information to Chargify for processing.

Interested parties can sign up for the service, still in beta, at the Chargify website.

Now, it goes without saying that Chargify is far from the first billing software for small- and medium-sized businesses; competitors such as FreshBooks are fast becoming well-known heavy hitters in the space. We also found a couple billing services that offer an API – the Dutch MoneyBird, and two English-language services, Zuora and Vindicia. What – if anything – makes Chargify truly competitive in this increasingly crowded space?

Now that we have online office suites like Google Docs, Zoho, and even Adobe’s Acrobat.com, you may not have much desire to go and check out yet another would-be Microsoft Office killer. However, Shutterborg, a new online word processor does one thing really well which makes it a unique tool in this space: it lets you open any URL on the internet and edit it like an Office document.

Sponsor

When you first visit Shutterborg, available online at http://shutterb.org, you’re presented with three options: New Document, Open from Disk (coming soon), and Open from Web. The first option – starting a new document – will take you right into Shutterborg, where you can then begin to type.

The word processor itself is rather rudimentary. There are some basic options for formatting your text, aligning it, highlighting it, etc. You can also choose to insert photos and links from the “Insert” menu or create bulleted and numbered lists. Beyond that, the tool doesn’t do much in terms of word processing. Also, at the moment, the files you create can only be saved in .HTML format. Other formats like .TXT, .ODT, and .DOC will arrive in later, says the company.

If basic word processing was all that Shutterborg did, it probably wouldn’t be worth a mention just yet. However, the “Open from Web” option that is presented to you upon launch is a pretty clever invention. Here, you can enter in any URL on the internet to open an exact replica of that web page, with the CSS and images intact. You can then edit it as you desire which could obviously lead to some humorous creations.

That feature alone makes Shutterborg worth a look simply because it's so easy to use. Although the resulting HTML file won't look like much if opened outside of the Shutterborg processor, it's easy enough to grab a screenshot of your mocked up creation while you have Shutterborg open. The potential for creating hilarious edits to well-known sites will certainly appeal to the creative types out there. We can't wait to see what they come up with. 

Shutterborg is a creation of developIT, a small business in Waterloo, Ontario, Canada whose focus is on developing web sites and Rich Internet Applications (RIAs) for businesses of all sizes.

When it comes to Web design and development, one thing trumps the latest technology and cool features: usability. Why? Because all of the features and functions in the world are completely worthless if a human user is unable to figure out how to use them. But testing against human factors, creating use cases, and observing focus groups can prove to be a costly endeavor for even the largest of companies.

Now, there’s a cost-effective means of seeing how usable your pages are: Userfly, a simple way to test your site’s usability for free – with one line of code.

Sponsor

Simply add the Userfly code to your site, and you’ll soon be a fly-on-the-wall as users walk through your pages. That one line of code allows Userfly to record a screencast of your users’ behavior, providing some very interesting feedback on how they are interacting with your site, from simple mouse tracking to complex interactions with AJAX elements.

The user behavior is recorded for the entire site visit, following the user from page to page. Once the user leaves the site, the capture ends.

Reviewing the walkthroughs is just as easy. Userfly provides information on the user’s browser, each page visited, and time spent on each page. Clicking on a particular page plays back the interaction, showing where the user moved his or her mouse and where he or she clicked. Once you’re finished watching, you’re prompted to rate the usefulness of the capture. Then, you can decide to keep it or discard it.

Even during a short test, I found Userfly incredibly helpful – given that a number of users stopped by as I was testing the app. In fact, the only complaint I had was that the walkthrough fails to automatically pan as the user scrolls. Meaning? Meaning you have to manually scroll to keep up with the mouse movements – which I found to be nearly impossible on lengthy posts.

When the user didn’t scroll, however, I found myself replaying the walkthroughs over and over. It was invaluable to see how other users see and use the pages that I find so familiar. Suffice it to say, I immediately noticed areas for improvement.

Userfly will allow you to record 10 users per hour, monitoring basic events for free. Those who are interested in more users per hour and more advanced events can contact Userfly for a quote.

How are people using your site? Wouldn’t you like to know? Grab the code at Userfly and take a look at your site through someone else’s eyes.

Just about half a year ago, Google announced a limited beta of Friend Connect, which allows site owners to display OpenSocial based gadgets on their sites and site visitors to sign in to these social gadgets with their OpenID, AIM, Yahoo, or Google accounts.

Amit Agarwal has been keeping a close eye on Friend Connect since it was announced and he assumes that the service could go live pretty soon. Just last week, Google published a new YouTube video geared towards users and now the support site for Friend Connect is available as well.

Sponsor

Some of the gadgets Google currently supplies are a comment wall and a ratings gadget. Friend Connect will also work with third-party applications built by the OpenSocial developer community. To enable these gadgets, all a site owner has to do is to copy and paste some code snippets into their site’s HTML.

Google Profiles Meets MyBlogLog

Lately, Google has started to put a lot more emphasis on its own user profiles, and Friend Connect makes good use of them. Once you join a Friend Connect enabled site, other users will be able to see information from your profile, though you can set your privacy settings to disallow others from seeing your profile pages as well. In many ways, this is quite similar to MyBlogLog.

It’s Social, But is it Open?

When Friend Connect was first announced, we were concerned about the direction Google was taking with this implementation of the OpenSocial standards. Also, as we noted in our earlier posts, the Friend Connect apps are displayed in an iframe, which is basically a separate web page inside another web page. Because of this, these apps are black boxes that live on your site, but don’t allow the site owners to really leverage the data from these apps on their own sites.

It is interesting to note that the latest Google video about Friend Connect still prominently features Facebook as a supported service, even though Facebook has decided to eschew OpenSocial in favor of its own platform. The help pages for Friend Connect don’t feature a list of supported services yet.

Benefits

There are, however, also some clear benefits to using Friend Connect. Through this service, a site owner might be able to create more user loyalty and enthusiastic readers can evangelize your site by publishing their activity on it to their own social network. Visitors will also be able to invite their friends on social networks to join your site.

In an early press release about Friend Connect, Google stated that this initiative was about helping the 'long tail' of sites to become more social. While we might worry about  some of the details of Google's implementation, this by itself is a worthy cause, and it will be interesting to see how site owners will implement Friend Connect once it becomes publically available.

Yahoo’s Exceptional Performance Team just released an interesting tool that optimizes images for publishing on the web. Smush.it is completely cloud-based and you can choose to upload your images directly to the service, provide Smush.it with a URL, or use a Firefox plugin that analyzes a whole page at once. Smush.it provides a one-stop shop for compressing images and works with JPGs, PNGs, GIFs, and animated GIF files.

Sponsor

As Yahoo points out, there are already many image editing tools on the market that perform similar functions. Smush.it, however, automates this process and works for a variety of popular file formats, taking a lot of the hassle out of the process.

Crunching Numbers and Stripping Out Metadata

Smush.it works on two different levels. First, it strips all the metadata out of the file. For small files like logos or buttons, this data can make up a large part of their size and very few users will ever care what editor you used to create a button. After this, Smush.it applies a number of non-lossy, open-source image optimization algorithms to the image. Smush.it will also transform GIFs into more efficient PNG files when necessary and optimize PNGs and animated GIFs.

For most web pages we tested, Smush.it reduced the total image size by anywhere from 10 to 45%. For most sites, logos, buttons, and icons saw the largest improvements (often close to 90%), though we also noticed a lot of sites that did not optimize their screenshots and other images, which Smush.it was usually able to compress by anywhere between 10 to 30%. If you are a web developer or publisher, using Smush.it could potentially reduce your bandwidth bill significantly.

We only wish that Yahoo had picked a slightly less unfortunate URL for the service…

RSS is magic and the things we do online are often beautiful – so why are all the interfaces for displaying the feeds of our activities so ugly? Enter Swurl, a visually stunning system for displaying a timeline of your activities on various sites around the web.

Developer Ryan Sit specializes in leveraging the visual to create new interfaces for data, his ListPic application lets users browse Craigslist by images. Just like Listpic creates a whole new experience for Craigslist, Sit hopes that Swurl will make interacting with lifestream data a much more visually enjoyable experience.

How it Works

The most important part of Swurl is the timeline view, where all the messages, bookmarks, album covers and photos you’ve saved in various services are organized in a calendar view. It’s a great way to look back at days gone by – we’ve found already that it can’t help but put your experiences into a different perspective.

In addition to the timeline view, Swurl also publishes your activities in a blog-type format. Each person’s blog is highly customizable. If you’ve hesitated to send the URL to your crazy-chaotic FriendFeed page to your grandma, maybe you should send her to a Swurl page instead.

Inside of each item you’ll find all kinds of visual treats, like a nice slideshow viewer, song lyrics displayed below the Flash audio player for each song in your time line and elegant captions on your photos. There are lots of nice little touches here and we hope it will only continue to improve.

One of the areas the app could really use improvement is in viewing your friends’ activities. You probably don’t want to use it for that, unless it’s very casual. Swurl discovers your friends on various services but displays their activities in a boring list that’s spotty and hours behind.

The big picture here for us is that RSS feeds and lifestream data in particular can really look great when displayed nicely and mashedup with various sources of data. By grouping your activities into a calendar view, Swurl really facilitates a change in perspective. We think you’ll enjoy this app and we are excited to see where it goes in the future.

If you’re a developer who loves to build mashups – especially map mashups – then you have to check out the library provided by Mapstaction. (And if you’re end user, wait until you see the demos!) Mapstraction is library that provides a common API for various mapping APIs already in existence. This allows developers to use the Mapstraction API to build a mashup that supports nine of the major mapping providers including Google Maps, Microsoft’s Virtual Earth, Yahoo Maps, and more.

There are several reasons why a developer might want to use the Mapstraction library to build a mashup. For one, they would only need to code their apps once and then they could switch the mapping provider as necessary when their project’s needs changed. A ProgrammableWeb post points to another possibility, which is that Mapstraction allows for building a map where the end user could select which mapping provider’s base they want to see.

In addition, Mapstraction “fills some holes each provider’s current offerings” – meaning if a certain mapping provider doesn’t offer a particular feature that another one does, Mapstraction turns to open source solutions (for the most part) to provide the feature needed.

Those are the technical details, but what’s really impressive about Mapstraction are the demos. Take, for example, this demo, a single page showing several maps. As you move around in one map, the other three also move simultaneously to reflect the changes that take place in the map you’re using. This is a great way to view comparisons of the different mapping systems side-by-side.

Another feature of Mapstraction allows for tile layer support. This feature lets you toggle different overlays on top of a mapping provider’s map, like this one. Clicking the links below this map let you toggle different overlays on top of the Google Map to see maps from 1950, 1912, and 1877.

This demo takes you to a full screen map where you can switch from mapping provider to mapping provider by selecting the name in the box displayed in the bottom-left corner. (Note: to exit the demo, you’ll need to know your browser’s keyboard shortcut to go “back”).

Mapstraction isn’t exactly new, having debuted back in 2006. It’s currently in use in places like the UK’s Nestoria, Mapufacture, Reuters Labs, and even powers a WordPress and MT plugin called GeoPress, which adds geo-tagging to your posts and pages.  However, we would like to see some more Mapstraction mashups – so if you've built one, let us know in the comments.

Soulseek, which was creted by former Napster programmer Nir Arbel and visibly resembles early versions of Napster, is not one of the most popular filesharing apps. It doesn’t have the mainstream appeal of Kazaa or Limewire, nor does it garner the press attention of BitTorrent. And that’s all probably fine with its users, who tend to gravitate toward more independent musical fare. But Soulseek has done something the others haven’t — made the jump to the iPhone.

Developer Errrick created iSlsk, a new filesharing client for jailbroken iPhones that works with the Soulseek network, by basing it on open source versions of the client for the Mac. “I saw all the capabilities this little gadget had and then thought ‘why didn’t someone already do something like this?’” he told TorrentFreak.

iSlsk lets iPhone users search for and download files directly on their phone. The software also imports downloaded files to the iPod music database so that they can be played with native iPhone controls.

This is not an application you'll ever see in the upcoming official iPhone application database. Apple certainly won't let applications that a) potentially facilitate illegal file sharing and b) cut into their iTunes Store revenue into their official app distribution channels. If iSlsk and other music and video sharing applications catch on, will we continue to see jailbroken iPods even after the release of the official app store? Even if Apple starts selling phones that aren't tied to AT&T?

A video of the of the app in action is below:

Sometimes you stumble across something that really makes you say “wow” and reminds you that there’s so much more to this internet thing than just the latest web app. Case in point is this article describing some of the visual resources available on the web. The deep web. These images won’t show up in search engines’ image searches or on Flickr (save one exception), but instead can only be accessed via the links below.

The images are a part of online collections created by institutions in the U.S. Some of the images may be a part of the public domain, but many will require permission or accreditation in order to use. So, no, these aren’t necessarily images you can use in your next blog post, but that doesn’t mean they’re not useful. Instead, if given permission, these images could be used in the classroom, in private study, or even included in a media project or publication.
