10 Top Web Apps

Computer Comments Off

Online apps let you become more productive on the move, doing away with software installation entirely.

Thanks to the ubiquity of internet access, web-based applications are taking off like never before. Beyond the realms of Twitter and Facebook lurks a fresh and vibrant world of online software that’s designed to run anywhere on our connected planet.

As the distinction between computers, mobile devices and the internet continues to blur, web applications are coming into their own, becoming globally important services. These are sites that do one useful thing and do it well.

But sites promoting applications have been around for donkey’s years, you might say. What’s the difference between a web app and an application that’s available for download on the web? Well, web apps are applications that run over the internet. So unlike the free utilities hosted on Sourceforge or similar, there’s no download, installation or configuration to carry out, nor hours of frustration to endure while you try to find the right libraries to compile them. Just point your browser at the relevant website and it will do the rest.

Outside of the box

Freed from the restrictions of an operating system’s windowing subsystem, software designers can allow their imaginations to run riot. Interfaces that owe more to high-tech thrillers than to Windows, Linux or Mac OS X are beginning to appear. Also emerging are more intuitive drag-and-drop interfaces that require at most a few seconds of exploration to get you going. Software use is slowly evolving and becoming as much about discovery and experimentation as it used to be about reading manuals and clicking options.

In this special roundup, we bring you 10 cool web apps that all share these traits. It’s a diverse bunch, ranging from future essentials to those that you’ll need infrequently. They all exhibit the sort of rich functionality that is beginning to appear through the medium of web browsers, and remove the need to download and install an application suite. If you want something, it’s probably already been written, and so we’ve also included a site that will help you to find other incredible web applications. Happy browsing!

Newsmap

Newsmap is a global news aggregator site like no other, and it’s almost guaranteed to get people peering over your shoulder as you use it. The app presents a page covered in blocks of different sizes. Each represents a story, coloured by subject. Newsmap takes input from news feeds and then gives the stories that are more prominent bigger boxes on-screen, a little like a tag cloud. Simply move your mouse over a story to see its details and a link to the original article.

Instapaper

Instapaper is a way of bookmarking long web pages so that you can read them when you have time later on. The URLs are stored in Instapaper’s central database, so you can access them from anywhere. A range of iPhone apps support it, as does the Kindle, making it flexible and a great way of keeping hold of interesting things to read on long journeys. To use Instapaper, drag and drop the ‘Read Later’ icon onto your toolbar. When you subsequently find a page you want to save, just click the icon.

Lovely Charts

There are plenty of times when you need access to some good chart-drawing software for just half an hour. However, it’s usually supplied as part of a far larger application. Lovely Charts is different. It’s a free web app that creates some very lovely charts indeed. After signing up and creating a new document, you simply drag and drop symbols and connectors from a range of predefined types to create the chart you want – anything from a simple flowchart to a complex route map.

Bing Visual Search

Bing’s Visual Search capability is still in beta, but it’s already showing promise as a new way to search the expanding universe of information out there. On the main Bing page, click the ‘Visual Search’ link. Search categories are organised into galleries, and everything is point-and-click. Instead of typing in your search term, you simply click the relevant picture. The list of galleries is still small, but it’s an interesting glimpse of what could be to come.

Fonolo

Calling Fonolo a work of genius is perhaps a little strong, but if you’re heartily sick of wading through phone menus to talk to a human being then it probably comes close. Fonolo walks you through company phone systems to find a human voice. If a company isn’t listed, you can add your own, and test the service by calling special test hardware set up by the developers. Ideal for Skype users, Fonolo’s is also available for the iPhone, which should see its popularity rise further.

Netvibes

Netvibes allows you to create what it calls a dashboard for your interests. Unlike a simple RSS feed reader, the app has a large number of widgets that present feeds from your favourite sites in a highly editable form, making it very customisable. Netvibes is also partly a social-networking service. People can follow you and read your public page if their interests are the same as yours. For the sake of privacy, you can also set up a private page with feeds that only you can see.

Floor Planner

People are crazy about home improvement at the moment, but good, free planning software is hard to find. The free version of Floor Planner allows you to create a plan, make specific rooms and then decide where to place the windows, doors and any of a large number of items of furniture. You can inspect your work in 3D from any angle to see exactly how your ideal home would look. You can then save your work and send it straight to your architect – easy peasy!

Wakoopa

The brainchild of Dutch founders Wouter Broekhof and Robert Gaal, Wakoopa is a social-networking site that is designed to help its users discover new web apps and other software they might enjoy. It does so by first searching for people that use the same apps and installed software as you do. It then finds the software they use but you don’t, and which they rate highly. These it recommends to you. But how does Wakoopa know what software you and others use? A downloadable tracker monitors the sites you visit and the installed applications you use.

Every 15 minutes, it sends this information to your Wakoopa profile for those on your contacts list to take a look at. When your contacts search for new apps, this information is cross-matched with their own to generate a selection of software recommendations picked especially for them.

It’s a simple idea, and one that lets you explore an ever-expanding universe of web apps and installable applications and utilities without ever having to spend hours scouring the web for information – plus you know that none of the programs will turn out to be malware.

Explore and amaze

Once the tracker is installed, right-clicking on the Wakoopa icon in the system tray enables you to suggest a new application that others may like to try. To keep the underlying database free of spam, any suggestions you make that aren’t either installed apps or something that runs in your browser will not be accepted.

When you find a particularly intriguing application in Wakoopa that you’ve never heard of before, clicking on its symbol opens a page giving its details, alternatives that you might like to try and – perhaps most importantly – both good and bad comments from its existing users. This enables you to quickly make decisions about whether to use the app without the frustration of downloading and installing it, only to later discover that it’s not for you.

As well as relying on custom recommendations generated via your contacts list, you can also use the Wakoopa search box to simply enter an application field, making software experimentation as easy and hassle-free as it could ever possibly be.

RescueTime

You’re in the middle of writing an important email but the right words won’t come, so you decide to spend a couple of minutes reading your friends’ statuses on Facebook to clear your head. By the time you’re finished, you fancy having a look at what the celebrities on Twitter are up to. News doesn’t read itself, so it’s off to the RSS feeds next, stopping on the way back to drop by a hobby forum. Armed with more coffee after posting a detailed rebuttal of another forum member’s argument, it’s time to check Facebook again for any replies, and perhaps to glance at Twitter again to make sure that Stephen Fry hasn’t unexpectedly returned. What began as a break to clear your head has somehow blossomed into over an hour of wasted time.

With so many cool new web apps appearing, distractions can only get worse. Some are great for getting things done, but without that vital pinch of self-control, we risk becoming ever busier while paradoxically achieving far less. RescueTime promises to show you how you spend your time online, and also to help you develop the increasingly important skill of self-control.

After installing a Data Collector plug-in, you tell RescueTime the three most distracting and three most productive things you do online. Data Collector then logs the time you spend using your local apps as well as the websites you visit, and can even monitor which of your browser tabs is active. You can also tell it to ignore the time you spend away from the PC so that you get an accurate view of your working day.

Once the Data Collector plug-in has gathered enough data, you can go to your RescueTime account and view detailed reports containing information on everything from the sites you visit to how efficiently you use your time based on how you categorise your activities.

The personal Solo Lite version of the service is free. The paid-for Solo Pro edition ($6 to $9 a month) allows you to block unproductive websites when you visit them too much, and alerts you when Data Collector notices you’re spending too much time dodging work. But you don’t need to splash out: the free service provides a fascinating insight, and helps you to learn a skill that will surely become as essential as using a search engine.

In May-July of this year I did a talk on Building Scalable and Usable Web Applications in
Indianapolis, Downers Grove, Milwaukee, Chicago and Appleton for our ArcReady series
that we run in about 18 cities in the Central United States.  One of the items
I mentioned as a good reference for learning about the ins and outs of web site scalability
was the book Building
Scalable Web Sites
by Cal Henderson,
the chief architect of Flickr.

Quick Review

This is a great book for someone who wants to understand the issues with creating
a truly Internet Scale application.  The title of this book is a little misleading,
because it is about much more than just scaling out your web site.  With chapters
on Internationalization / localization and other important topics, it really should
be called something like “Handbook for creating an Internet application”.  If
you are a Flickr fan, it is also a very interesting peak into how some of the features
of the site are implemented.  This is one of the few technology books that I
have read more than once, it is that valuable of a resource.  It is also a great
book to keep on the shelf and revisit specific topics as you work on creating your
next great Internet web site.

Street Credibility

I suppose that anyone could write a book on building scalable web applications, but
there are a select few sites on the Internet that have achieved true Internet Scale. 
Internet Scale is a term that gets thrown around a lot, but to cut through the clutter
I would just say that if you are in the top 100 traffic sites, you are pretty much
there.  And the fact that Flickr is a photo sharing site adds a lot to his discussions
on scaling web applications.  The fact that literally hundreds of people are
uploading multi-megabyte photos to the site every minute, 24 hours a day is a real
testament to the scalability of the site. 

Standing the test of time

One of the hallmarks of a good technology book is that it stands the test of time
(for at least a few years).  You can go to any used books store and find lots
of copies of Visual Basic .NET 1.1 books that are less than 5 years old that are collecting
dust, because they were too wired into the specific features of the technology from
that slice in time.  They may have been great books at the time, but their shelf
life (pun intended) was as long as the technology was new and hot, once Visual Basic
.NET 2.0 came out, the 1.1 books were yesterday’s news.  The Henderson book does
a good job of focusing on the architecture and fundamental development issues around
large scale web sites, as opposed to focusing on specific features in any platform,
language, tool or technology.  A good example of this is the fact that Flickr
is not written on Microsoft technologies (most of it is PHP), but I got a lot out
of it, even though I primarily work with the Microsoft web stack.

A word of caution

If you are currently experiencing a scalability problem with your web application,
this book will not necessarily solve the problem for you.  You will not turn
to page 10 and see the list of common scalability issues, see that you are experiencing
number 8 on the list and then turn to page 101 for the answer to that problem. 
This book does make you think about the root causes of the scalability issues in your
application, and more importantly it is a great guide to follow as you start to add
new features to your application.

[After a few not so technological posts, getting back to tech…]
When planning a (web) application, everyone fantasize on the tons of users that would use this ‘amazing app’. It’s great to dream but what happens if the dream comes true :-) Assuming the architecture is scalable and was designed for large amount of users, you would still need the computing power for that (CPU, memory, DB, network…). And what happens until you reach millions of users and ‘just’ have dozens of thousands of users – how can you stretch your infrastructure to support it?
For that you need flexible scalability… I gave a try to two leading solutions:
Google App Engine – “Enables you to build web applications on the same scalable systems that power Google applications”
Amazon Elastic Compute Cloud (EC2) “A web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.”

My intermediate impression after working with both solutions for a short time is:

Google App Engine is relatively simple to use. You just need to have Google account and after a short registration you have your engine setup and free for usage until you reach ~5 million monthly page views (did not manage to test that…). It contains an ‘offline’ SDK that allows you to develop and test the application locally and then to upload it to their environment which makes it easy. The main drawback (for me) is that it is designed for running web applications using a specific engine based on the Python programming language which requires learning a bit but by using the tutorial it is still easy to use.

Amazon EC2 is actually part of a bunch of web services that allow using Amazon scalable platform for building apps by consuming processing power, storage, etc’. It’s not free and you pay for the usage (CPU time, storage, network traffic and some other parameters).Basically it allows to choose a machine image with relevant applications and to run number of instances based on the need. However although it allows using variety of machine images, containing different types of applications, it is not completely straightforward (flexibility has its cost). As it’s not free – I had to pay for my tests – up till now only 50 cents, but on the other hand, I managed only to run an existing image and even did not manage to get a proper web page shown.

Hope next time I will have more impressive results…
