Google’s G1: First Impressions

noreply@blogger.com (Arvind Panwar) — Fri, 26 Sep 2008 06:24:00 +0000

Google’s new G1 phone announced today is the first real competitor to the iPhone. Like Apple’s product, it’s a serious handheld computer with a powerful new operating system (called Android) and a clever touch-based user interface. Like the iPhone, it’s likely to be a major new platform for third-party software. But it’s also very different, and may appeal to different buyers.
The phone, expected to be the first of many to use the Android operating system, was largely designed by Google, and was built by HTC of Taiwan. It will be sold in the U.S. starting next month by T-Mobile, for $179 with a two-year contract.
Here are some first impressions of the G1, based on some experience with a prototype. This isn’t a full review; that will come later, when I’ve had a chance to use a more finished device.
Most importantly, the G1 complements its touch screen with a physical keyboard, the lack of which has made the iPhone a non-starter for some users. The G1’s keyboard is revealed when you slide open its screen. The keys are a bit flat, and you have to reach your right thumb around a bulging portion of the phone’s body to type, but it’s a real keyboard. And there’s also a BlackBerry-like trackball that supplements the touch screen navigation. I found typing on this keyboard to be OK, but not great.
A second big feature, or limitation, of the G1 — depending on your point of view — is that it is tightly tied to Google’s web-based email, contacts and calendar programs. In fact, you must have a Google (GOOG) account to use the phone, and can only synchronize the phone’s calendar and address book with Google online services. Unlike the iPhone, it doesn’t work with Microsoft Exchange, and it can’t physically be synced with a PC-based calendar or contacts program, like Microsoft Outlook.

Are you using Google Docs (mean sharing)

noreply@blogger.com (Arvind Panwar) — Wed, 17 Sep 2008 08:13:00 +0000

Google Docs mean sharing: "Google Docs is all about being able to share and collaborate, and now we're taking the idea of sharing a step further with a new Google Docs Community Channel. This is a place to watch videos from regular folks all about Google Docs, connect with others, and pick up smart tips about all the ways to use the application."

Insight into YouTube videos

noreply@blogger.com (Arvind Panwar) — Wed, 17 Sep 2008 08:12:00 +0000

Insight into YouTube videos: "I remember the first time a video I posted to YouTube cracked 100 views. I wasn't so much surprised as curious: Who were these people? How did they find this video? Where did they come from?

Today we're taking our first step towards answering these questions with YouTube Insight, a free tool that enables anyone with a YouTube account -- users, partners, and advertisers -- to view detailed statistics about the videos that they upload. For example, uploaders can see how often their videos are viewed in different geographic regions, as well as how popular they are relative to all videos in that market over a given period of time. You can also delve deeper into the lifecycle of your videos, like how long it takes for a video to become popular, and what happens to video views as popularity peaks. For now, you can find currently available metrics by clicking under the 'About this Video' button under My account > Videos, Favorites, Playlists > Manage my Videos."

AdSense for video now in beta

noreply@blogger.com (Arvind Panwar) — Wed, 17 Sep 2008 08:11:00 +0000

AdSense for video now in beta: "In a very short time, watching videos online has become a common pastime, and the imagination of artists and other content owners continues to fuel this trend. Meanwhile, across the industry, advertisers and video publishers continue to look for the best solution that balances the needs of video fans with the need for video sites to generate the revenue that enables them to continue to be creative as they grow"

Video-sharing goes to work

noreply@blogger.com (Arvind Panwar) — Wed, 17 Sep 2008 08:08:00 +0000

Video-sharing goes to work

Ten years ago the world of online video was little more than an idea. It was used mostly by professionals like doctors or lawyers in limited and closed settings. Connections were slow, bandwidth was limited, and video gear was expensive and bulky. There were many false starts and outlandish promises over the years about the emergence of online video. It was really the dynamic growth of the Internet (in terms of adoption, speed and ubiquity) that helped to spur the idea that online video - millions of people around the world shooting it, uploading it, viewing it via broadband - was even possible

How to Chat with Gmail contacts on the iPhone

noreply@blogger.com (Arvind Panwar) — Mon, 14 Jul 2008 10:39:00 +0000

Last week, Google launched a new version of Google Talk designed specifically for the iPhone. It works right in your Safaribrowser, so there's no need to download or install anything -- just go to talk.google.com and sign in.*

Because this version of Talk is designed to run in your browser, you'll be automatically signed out of Talk when you navigate to a different browser window or iPhone app. So while it's not a traditional "always-on" instant message client, it's useful for changing your status message on the go or checking in to see if someone's online and sending them a quick chat. It's equally nice for killing time at the airport.

*Google Apps users: visit http://talkgadget.google.com/a/your-domain.com/talkgadget/m from your iPhone's browser, but be sure to replace 'your-domain.com' with your actual domain name.

How to optimize Google Adsense

noreply@blogger.com (Arvind Panwar) — Wed, 09 Jul 2008 08:03:00 +0000

Following on the five tips on AdSense for content optimization our Sydney team presented a couple weeks back, now let's turn to AdSense for search. As you may know, we recently integrated Custom Search Engine into AdSense for search to provide additional customization options and improved targeting. Whether you've already implemented an AdSense for search box on your site or you're just getting started with this feature, we recommend these five optimization tips:

Place your search boxes in visible locations.

Integrate your search boxes in easy-to-find locations, such as under the header or in your left navigation. Also, keep the placement of your search boxes consistent on all your pages, so users will know where to look if they need help finding something.
Add two search boxes to content-rich pages.

For pages with a lot of content or which require scrolling, try placing one search box at the top of the page and another at the bottom. A box at the top of the page will allow users to perform a search immediately, and a box at the bottom will provide a search option to users who've just finished reading your content. You can also track and compare the performance of each search box by creating custom channels.
Host your search results on your own site.

To keep users on your pages, you can host your search results and ads within your own pages. If your users don't find what they're looking for in the search results or ads, they'll still be able to to navigate to other sections of your site using your site's template. In addition, you can further integrate your search results into your site by customizing the colors of the results page.
Add a search box to your search results pages.

Similar to #3, try placing a search box on your search results pages so users can perform additional searches from your site.
Customize your ad locations.

Place ads at the top and right sidebar of your search results pages. This layout offers added visibility, and our tests have shown that these ad locations can improve monetization.

How to use Google Reader with I Phone

noreply@blogger.com (Arvind Panwar) — Wed, 09 Jul 2008 07:54:00 +0000

Mobile web browsers have come a long way since we first introduced an XHTML version of Reader back in 2006. For example, iPhone and iPod Touch owners know how powerful having a full-featured browser is. We on the Reader team are heavy mobile Safari users. Sometimes we use it to kill time, other times for answering important questions that come up during brunch: What is Tyrol's first name? How is maple butter made? How do you sweeten rhubarb for sangria? What is John Gruber saying now? For questions like the last one, we of course use Reader to keep up with our subscriptions.
To make our (and your) Reader iPhone experience better, we wanted to really take advantage of the iPhone's capabilities. Today we're releasing a new beta version of Reader designed for the iPhone and other mobile phones with advanced browsers. You can use it by visiting http://www.google.com/reader/i/ on your phone.
This new version is designed to offer many of the same features as the desktop, while making it quick and easy to act on items. If you've used list view, then it should be familiar to you. Scan the titles for an item that interests you, tap and it expands in place. Starring, sharing, and keeping unread are done in place, so you never have to leave the list view or refresh the page. We think it's a very fast way to power through your reading list

How to check who has access to my Gmail account

noreply@blogger.com (Arvind Panwar) — Tue, 08 Jul 2008 14:39:00 +0000

Your email account can contain a lot of personal information, from bank alerts to love letters. Email that, I'm sure, you don't always want other people to see. We understand how important your Gmail accounts are to you, so we're adding a new layer of information and control. With this new feature, you can now track your recent sessions and you can also sign yourself out remotely.

If you are anything like me, you probably sign in to Gmail from multiple computers. I, for example, occasionally sign into my Gmail account from a friend's house when I need to check an important email. Usually I remember to sign out, but every once in a while I wonder if I really did. Now I no longer have to wonder.

At the bottom of your inbox, you'll see information about the time of the last activity on your account and whether it's still open in another location:

What is SnapShot

noreply@blogger.com (Arvind Panwar) — Wed, 25 Jun 2008 11:53:00 +0000

A snapshot represents a frozen image of a volume. The source of a snapshot is called an "original." When a snapshot is created, it looks exactly like the original at that point in time. As changes are made to the original, the snapshot remains the same and looks exactly like the original at the time the snapshot was created.

The snapshot feature is very useful for performing data backups. In order to perform a consistent backup, the volume that is being backed up should not change while the backup is running. This often means the volume must be taken offline during the backup, which can be a significant inconvenience to users. With snapshots, the volume can be kept online. A snapshot of the volume is created and the backup is taken from the snapshot, while the original remains in active use.

What are Different Types of Mashup

noreply@blogger.com (Arvind Panwar) — Sat, 17 May 2008 12:42:00 +0000

Mashups currently come in three general flavors: consumer mashups, data mashups, and business mashups.

The best known type is the consumer mashup, best exemplified by the many Google Maps applications. Consumer mashups combine data elements from multiple sources, hiding this behind a simple unified graphical interface.

Other common types are "data mashups" and "enterprise mashups". A data mashup mixes data of similar types from different sources (see Yahoo Pipes), as for example combining the data from multiple RSS feeds into a single feed with a graphical front end. An enterprise mashup (see Denodo Technologies and JackBe), usually integrates data from internal and external sources - for example, it could create a market share report by combining an external list of all houses sold in the last week with internal data about which houses one agency sold.

A business mashup is a combination of all the above, focusing on both data aggregation and presentation, and additionally adding collaborative functionality, making the end result suitable for use as a business application.

Mashups within mashups are known as 'monster mashups'.

Examples

Mashups can be divided into four main categories, mapping, video & photo, search & shopping and news.

Some examples of each are:

Mapping

Chicago Crime

The Chicago Police Department has a mashup which integrates the department’s database of reported crimes with Google Maps in order to help stop crime in areas and warn citizens of areas where the crime rate is high.

Video and Photo

Flickr

Flickr is an image storage site that allows users to organise their collection of images and share them. Through the use of its Application Programming Interface (API) the content can be used by other sites to create a mashup. Flickrvision is an example of a mashup made using Flickr's API.

Search and Shopping

Travature

Travature is a travel portal which has integrated airfare meta search engines, wiki travel guides, hotel reviews. It also allows the user to share photos and discuss experiences with other travellers.

News

Digg

Mashup of various news websites controlled almost entirely by the users of the website.

mashups

A "telecom mashup" is a telecommunications service where service elements come from more than one source and are combined into an integrated experience. For example, one could get the base service from company A, a ringback tone from company B, a voicemail service from company C, etc. Microsoft's Connected Services Sandbox is an example of a "service development environment" (also referred to as a "service development platform" or a "service development framework") that enables developers to more easily create telecom mashups.

Nested, embedded, sequential or recursive telecom mashups, where a large number of services are used, are considered risky or "over-the-top" (OTT) by network operators. Because of their complexity, such mashed up services can be difficult to control and charge, and therefore may cause operators to lose revenues. In addition, operators are subject to government fines or customer litigation from lax or overzealous conformance to Lawfully Authorized Electronic Surveillance (LAES) in the management of OTT mashups.

The following example of an over-the-top mashup is found in the online version of Pipeline magazine: "an address book lookup gives a name which is used to find a person’s location which brings up a map of reasonable trip routing, resulting in a call, once connected, linking in web co-browsing, with a location, type search to find for a restaurant along the trip route, clicking the restaurant’s advertisement, resulting in a reservation, and a message to social-network shared friends to met [sic] them with directions inserted from that person’s location."

Mashups versus portals

Mashups and portals are both content aggregation technologies. Portals are an older technology designed as an extension to traditional dynamic web applications, in which the process of converting data content into marked-up web pages is split into two phases - generation of markup "fragments" and aggregation of the fragments into pages. Each of these markup fragments is generated by a "portlet", and the portal combines them into a single web page. Portlets may be hosted locally on the portal server or remotely on another server.

Portal technology defines a complete event model covering reads and updates. A request for an aggregate page on a portal is translated into individual read operations on all the portlets that form the page ("render" operations on local, JSR 168 portlets or "getMarkup" operations on remote, WSRP portlets). If a submit button is pressed on any portlet on a portal page, that is translated into a single update operation on that portlet alone ("processAction" on a local, JSR 168 portlet or "performBlockingInteraction" on a remote, WSRP portlet). The update is then immediately followed by a read on all portlets on the page.

Portal technology is about server-side, presentation-tier aggregation. It cannot be used to drive more robust forms of application integration such as the one using Two-phase_commit.

Mashups differ from portals in the following respects:
Portal Mashup
Classification Older technology, extension to traditional web server model using well defined approach Using newer "Web 2.0" techniques
Philosophy/Approach Approaches aggregation by splitting role of web server into two phases - markup generation and aggregation of markup fragments Uses APIs provided by different content sites to aggregate and reuse the contents in another way
Content dependencies Aggregates presentation-oriented markup fragments (HTML, WML, VoiceXML, etc.) Can operate on pure XML content and also on presentation-oriented content (e.g., HTML)
Location dependencies Traditionally content aggregation takes place on the server Content aggregation can take place either on the server or on the client
Aggregation style "Salad bar" style - Aggregated content is presented 'side-by-side' without overlaps "Melting Pot" style - Individual content may be combined in any manner, resulting in arbitrarily structured hybrid content
Event model Read and update event models are defined through a specific portlet API CRUD operations are based on REST architectural principles, but no formal API exists
Relevant standards Portlet behaviour is governed by standards JSR 168, JSR 286 and WSRP, although portal page layout and portal functionality are undefined and vendor-specific Base standard is XML Data Interchange with REST semantics. RSS and Atom are commonly used. More specific mashup standards are expected to emerge.

The portal model has been around longer and has seen greater investment and product research. The technology is therefore more standardised and mature. In 2-3 years, increasing maturity and standardisation of mashup technology may propel it beyond portal technology in popularity. Alternatively, the two technologies may converge, with newer versions of current portal products resembling mashup servers using mashup techniques while still supporting legacy portlet applications.

In a business environment

Mashups can have a big role in the business environment. This section will discuss a few of the practical uses that could be made of this technology; with specific reference to, the end-user desire for personalised information services, addressing information overload issues, and the need for technology integration.

Mashups create new services for consumers which allow them to create a lot of new possibilities. It is becoming more straightforward for end-users to create mashup sites regardless of their technical skill level by using a site’s Application Programming Interface (API). This provides a simple way to implement mashups and new consumers can create a mashup easily. With all APIs available, enterprises can easily build applications that are cheaper, more reusable and more maintainable. The web 2.0 is all about the personalisation of information. In that context, mashups can grow faster since every mashup can offer new features from existing websites, in fact Emory M. Craig (2007) states that on Programmableweb.com around three new mashup sites are added every day. It’s easy to imagine how you can create a personalised information service when you have the ability to add features with mashups. As they are a part of the web 2.0, mashups increase the level of personalization of the Internet. Many people are convinced in the power of mashups and view mashups as the future of the web.

Information overload is a problem that many companies face, whether it’s within the company itself or when presenting information to users. Mashups can help overcome this problem by allowing one company to display detailed concise information derived from a wide variety of sources. For example, prior to mashup sites, users that wanted to find images of a particular type (e.g. animals) would first have to search for websites and then trawl through them trying to find suitable images. There are obviously a vast number of web sites that could potentially have suitable images on them; therefore the user would be presented with an overload of information. To help solve this problem, a mashup site could be created that pulls in the images from the other sites and categorises them. This would enable the user to easily search in one location for what they want, and even allow them to see all possible images within a particular category in a few clicks.

Mashups are a form of technology integration as they can be adapted to join together many technologies and use many types of implementation languages. Some mash-ups can be as simple as mixing together some JavaScript code with XML to create a new and innovative web-based service. Other larger mashups which are the main focus of their respective website will take advantage of services such as Google Maps and a database which uses street addresses to link the two together and project information onto the map.

Architectural aspects of mashups

For all appearances it would seem that a mashup is an example of a Facade pattern ( see Design Patterns: Elements of Resuable Object-Oriented Software (ISBN 0-201-63361-2) by the GoF, Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides ). I.e. It is a software engineering design pattern that provides a simplified interface to a larger body of code (in this case the code to aggregate the different feeds with different API's).
