  • What do you do with coder's block?

    - by Garet Claborn
    Lately it has been a bit rough. I basically know all the things I need and all the avenues to get there for work. There's been no real issue of a problem with too high complexity, and performance is good. Still, after three major projects this year, my mind is behaving a little strange. It's like I'm used to working in O(1+log(N-neatTricks)) but for some reason it processes in O(N^2)! I've experienced a sort of burnout after long deadlines and drudging projects before, but when it turns into a longer experience, I haven't found the usual suspects to be helpful. Take more walks Work on other code Overdesign everything until I feel intensely driven to just make it (sorta works) How can a programmer recoup from the specific hole in your head programming leaves after being mentally ransacked by these bloody corporations and their fancy money? Hopefully some of you have some better ideas, because I could really use another round of being looted and pillaged.I've often wondered if there are special puzzles or some kind of activity that would de-stress the tangled balance of left and right braininess programmers often deal with. Do any special techniques, activities, anything seem to help with the developer's mindset especially?

  • Thunderbird compact is taking forever

    - by mulllhausen
    One day I came in to work and found that our development server - a Ubuntu box had a full hard disk. I did a bit of investigation using the du command and it seems like mozilla thunderbird is the major culprit. After burning off some backups, the disk was left at 94%: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 895G 791G 59G 94% / none 4.0G 300K 4.0G 1% /dev none 4.0G 1.4M 4.0G 1% /dev/shm none 4.0G 140K 4.0G 1% /var/run none 4.0G 0 4.0G 0% /var/lock none 4.0G 0 4.0G 0% /lib/init/rw $ cd $ du -ch | grep [0-9]G 666G ./.thunderbird/ccsmcruu.default/ImapMail/mail.adofms.com.au 666G ./.thunderbird/ccsmcruu.default/ImapMail 667G ./.thunderbird/ccsmcruu.default 667G ./.thunderbird 2.2G ./.VirtualBox/Machines/iBike/Snapshots 2.2G ./.VirtualBox/Machines/iBike 2.2G ./.VirtualBox/Machines 2.2G ./.VirtualBox 670G . 670G total I did some reading and found that Mozilla Thunderbird does not compact files by default - i.e. all of the old emails that were sent to trash are still kept. One of the mailboxes used to get a lot of spam so I guess this accounts for the 667GB. I opened up Thunderbird to see how much space the inbox actually takes up and it turns out to be approximately 500MB - over 1000 times less than the stuff that has not been compacted over the years. So i right clicked on the inbox directory in the tree on the left of Thunderbird and selected 'compact'. I left it for about 12hours but even after that it still said 'compacting folder' on the status bar. I don't use Thunderbird on this PC - it belonged to a colleague who has left the company, however I do occasionally need to look through the inbox for references to the project I am working on, so deleting all traces of Thunderbird is not an option. My question is - is there any way I can monitor the progress of Thunderbird's compacting function? I would really like to know how long it is going to take. Also is there any way I can speed up the compacting process?

  • So Singletons are bad, then what?

    - by Bobby Tables
    There has been a lot of discussion lately about the problems with using (and overusing) Singletons. I've been one of those people earlier in my career too. I can see what the problem is now, and yet, there are still many cases where I can't see a nice alternative - and not many of the anti-Singleton discussions really provide one. Here is a real example from a major recent project I was involved in: The application was a thick client with many separate screens and components which uses huge amounts of data from a server state which isn't updated too often. This data was basically cached in a Singleton "manager" object - the dreaded "global state". The idea was to have this one place in the app which keeps the data stored and synced, and then any new screens that are opened can just query most of what they need from there, without making repetitive requests for various supporting data from the server. Constantly requesting to the server would take too much bandwidth - and I'm talking thousands of dollars extra Internet bills per week, so that was unacceptable. Is there any other approach that could be appropriate here than basically having this kind of global data manager cache object? This object doesn't officially have to be a "Singleton" of course, but it does conceptually make sense to be one. What is a nice clean alternative here?

  • Now Available: Visual Studio 2010 Release Candidate Virtual Machines with Sample Data and Hands-on-L

    - by John Alexander
    From a message from Brian Keller: “Back in December we posted a set of virtual machines pre-configured with Visual Studio 2010 Beta 2, Visual Studio Team Foundation Server 2010 Beta 2, and 7 hands-on-labs. I am pleased to announce that today we have shipped an updated virtual machine using the Visual Studio 2010 Release Candidate bits, a brand new sample application, and 9 hands-on-labs. This VM is customer-ready and includes everything you need to learn and/or deliver demonstrations of many of my favorite application lifecycle management (ALM) capabilities in Visual Studio 2010. This VM is available in the virtualization platform of your choice (Hyper-V, Virtual PC 2007 SP1, and Windows [7] Virtual PC). Hyper-V is highly recommended because of the performance benefits and snapshotting capabilities. Tailspin Toys The sample application we are using in this virtual machine is a simple ASP.NET MVC 2 storefront called Tailspin Toys. Tailspin Toys sells model airplanes and relies on the application lifecycle management capabilities of Visual Studio 2010 to help them build, test, and maintain their storefront. Major kudos go to Dan Massey for building out this great application for us. Hands-on-Labs / Demo Scripts The 9 hands-on-labs / demo scripts which accompany this virtual machine cover several of the core capabilities of conducting application lifecycle management with Visual Studio 2010. Each document can be used by an individual in a hands-on-lab capacity, to learn how to perform a given set of tasks, or used by a presenter to deliver a demonstration or classroom-style training. Unlike the beta 2 release, 100% of these labs target Tailspin Toys to help ensure a consistent storytelling experience. Software quality: Authoring and Running Manual Tests using Microsoft Test Manager 2010 Introduction to Test Case Management with Microsoft Test Manager 2010 Introduction to Coded UI Tests with Visual Studio 2010 Ultimate Debugging with IntelliTrace using Visual Studio 2010 Ultimate Software architecture: Code Discovery using the architecture tools in Visual Studio 2010 Ultimate Understanding Class Coupling with Visual Studio 2010 Ultimate Using the Architecture Explore in Visual Studio 2010 Ultimate to Analyze Your Code Software Configuration Management: Planning your Projects with Team Foundation Server 2010 Branching and Merging Visualization with Team Foundation Server 2010 “ Check out Brian’s Post for more info including download instructions…

  • Installation procedure RAC One Node

    - by rene.kundersma
    Okay, In order to test RAC One Node, on my Oracle VM Laptop, I just: - installed Oracle VM 2.2 - Created two OEL 5.3 images The two images are fully prepared for Oracle 11gr2 Grid Infrastructure and 11gr2 RAC including four shared disks for ASM and private nics. After installation of the Oracle 11gr2 Grid Infrastructure and a "software only installation" of 11gr2 RAC, I installed patch 9004119 as you can see with the opatch lsinv output: This patch has the scripts required to administer RAC One Node, you will see them later. At the moment we have them available for Linux and Solaris. After installation of the patch, I created a RAC database with an instance on one node. Please note that the "Global Database Name" has to be the same as the SID prefix and should be less then or equal to 8 characters: When the database creation is done, first I create a service. This is because RAC One Node needs to be "initialized" each time you add a service: The service configuration details are: After creating the service, a script called raconeinit needs to run from $RDBMS_HOME/bin. This is a script supplied by the patch. I can imagine the next major patch set of 11gr2 has this scripts available by default. The script will configure the database to run on other nodes: After initialization, when you would run raconeinit again, you would see: So, now the configuration is ready and we are ready to run 'Omotion' and move the service around from one node to the other (yes, vm competitor: this is service is available during the migration, nice right ?) . Omotion is started by running Omotion. With Omotion -v you get verbose output: So, during the migration you will see the two instance active: And, after the migration, there is only one instance left on the new node:

  • Upgrading from 2005 to R2

    - by DavidWimbush
    We're about to take the plunge and upgrade our servers from SQL 2005 to SQL 2008 R2. Real world accounts of people upgrading to R2 are a bit hard to find so I thought it might be useful to blog what happens. (I don't count marketing 'case studies' that just say stuff like "The process was effortless and the upgrade will pay for itself by the end the week.") We're using the database engine, Analysis Services and Reporting Services so upgrading by a major version number was looking a bit daunting. I wasn't expecting much trouble on the engine side of things but, as most of the action in 2008 and R2 appears to have been on the Reporting and BI front, I expected to have quite a bit of work to do. But our testing so far has been one nice surprise after another: The 2005 backups restore cleanly onto R2. R2's BI Studio upgraded the Reporting and Analysis Services solutions without any issues. The cubes all deployed and processed just fine. R2 BI Studio interacts fine with TFS 2008 version control. I'll blog some more as things develop.

  • How do I completely self study computer science?

    - by Optimus
    Being a completely self taught programmer I would like it if I could better myself by self-learning computer science course taught to a typical CS grad. Finding different resources on internet has been easy, there is of course MIT open course ware, and there are Coursera courses from Stanford and other universities. There are numerous other open resources scattered around the Internet and some good books that are repeatedly recommended. I have been learning a lot but my study is heavily fragmented, which really bugs me, I would love If somewhere I could find a path I should follow and a stack I should limit myself to so that I can be sure about what essential parts of computer science I have studied and systematically approach those I haven't. The problem with Wikipedia is it doesn't tell you whats essential but insists on being a complete reference. MIT open course ware for Computer science and Electrical Engg. has a huge list of courses also not telling you what courses are essential and what optional as per person's interest/requirement. I found no mention of an order in which one should study different subjects. What I would love is to create a list that I can follow like this dummy one SUBJECTS DONE Introduction to Computer Science * Introduction to Algorithms * Discrete Mathematics Adv. Discrete Mathematics Data structures * Adv. Algorithms ... As you can clearly see I have little idea of what specific subjects computer science consists of. It would be hugely helpful even if some one pointed out essential courses from MIT Course ware ( + essential subjects not present at MIT OCW) in a recommended order of study. I'll list the Posts I already went through (and I didn't get what I was looking for there) Computer science curriculum for non-CS major? - top answer says it isn't worth studying cse How can a self-taught programmer learn more about Computer Science? - points to MIT OCW Studying computer science - what am I getting myself into? Overview of computer science, programming

  • Bingbot seems to be adding "ForceRecrawl: 0" to URLs when crawling my sites

    - by Louis Somers
    I'm seeing this in the iis-logs of two websites that I maintain: GET /an/existing/page/on/my/site+ForceRecrawl:+0 - 80 - 207.46.195.105 HTTP/1.1 Mozilla/5.0+(compatible;+bingbot/2.0;++http://www.bing.com/bingbot.htm) I get about one or two of these per day from these IP addresses: 207.46.195.105, 65.52.110.190.. an more, all belonging to msnbot-ip.search.msn.com Probably Microsoft has a bug in their crawler? Any way, doing a search on "ForceRecrawl: 0" in major search engines comes up with a bunch of random sites. Doing the search on StackOverflow or here gave no results (to my amazement). Am I the only one seeing this? I first noticed these on the 9th of this month, and I'm seeing them pass almost daily since... Another thing that I think is crazy, is that the URL http://www.bing.com/bingbot.htm redirects to mail.live.com (hotmail). Currently I'm returning 404's but I'm considering to catch these, strip the trailing " ForceRecrawl: 0" and process as if it were a legitimate url. Could anyone shed some light on this? Could it have to do with some configuration or so in Bing's Webmaster Tools?

  • Code Bubbles: Disruption comes to the IDE

    - by andrewbrust
    If you’re like me, you might see the open source Eclipse IDE as a copy or, more generously, a port of the Microsoft’s Visual Studio for the non-.NET world.  It’s not that Microsoft invented the IDE (I would credit Borland with that), but they really took the idea and ran with it for the first version of Visual Studio .NET in 2002.  The question is whether someone outside of Microsoft could take the modern IDE yet another major step forward in both principle and productivity. I think that has actually happened already, and I think the innovator in question is a second-year Computer Science PhD student at Brown, named Andrew Bragdon.  His project, which he calls Code Bubbles, is an IDE that allows for editing, debugging and exploration of code in “bubbles” which remind me a little bit of the discrete note tiles on OneNote…but they’re much more than that.  Bubbles actually allow for call stack traversal, saved debug sessions, sophisticated breakpoint and value watch behaviors and more.  And because bubbles, unlike windows, are borderless, and focus on code fragments rather than whole files, the de-cluttering effect is unbelievably liberating.  The best way to understand what Code Bubbles does is to watch the screencast video:     Code Bubbles is an IDE for Java development.  Why didn’t Microsoft come up with something like this for .NET devs?  Between the existing features in Visual Studio 2010, its WPF code editor, and the fact that OneNote’s UI bears some affinity to Code Bubbles’, it’s interesting that Microsoft still has not thought outside of its own “box” to get us something like this. Heck, that’s easy for me to say.  But it’s easy for you to say that you’d like something like this in Visual Studio sometime soon.  That’s because the ASP.NET site within UserVoice is taking votes on this very issue.  Just click this link and vote! Thanks to my fellow Microsoft Regional Director Sondre Bjellås for making me aware of Code Bubbles, and to RD Steve Smith for creating the UserVoice voting option.

  • Does OSB has any database dependency?

    - by Manoj Neelapu
    Major functionality of OSB is database independent. Most of the internal data-structures that re required by OSB are stored in-memory.Reporting functionality of OSB requires DB tables be accessible.http://download.oracle.com/docs/cd/E14571_01/doc.1111/e15017/before.htm#BABCJHDJ It should hover be noted that we can still run OSB with out creating any tables on database.In such cases the reporting functionality cannot be used where as other functions in OSB will work just as fine.We also see few errors in the log file indicating the absence of these tables which we can ignore.  If reporting function is required we will have to install few tables. http://download.oracle.com/docs/cd/E14571_01/doc.1111/e15017/before.htm#BABBBEHD indicates running RCU recommended. OSB reporting tables are bundled along with SOA schema in RCU. OSB requires two simple tables for reporting functionality and installing complete SOA schema is little far fetched. SOA schema contains lot of tables which OSB doesn't require at all. More over OSB tables are too simple to require a tool like an RCU.Solution to it would be to manually create those tables required for OSB. To make  life easier the definition of tables is available in dbscripts folder under OSB_HOME.eg. D:\Oracle\Middleware\osb\11gPS2\Oracle_OSB1\dbscripts. $OSB_HOME=D:\Oracle\Middleware\osb\11gPS2\Oracle_OSB1If you are not planning to use reporting feature in OSB, then we can also delete the JDBC data sources that comes along with standard OSB domain.WLST script to delete cgDataSources from OSB domain . OSB will work fine with out DB tables and JDBC Datasource.

  • Using an Apt Repository for Paid Software Updates

    - by Scott Warren
    I'm trying to determine a way to distribute software updates for a hosted/on-site web application that may have weekly and/or monthly updates. I don't want the customers who use the on-site product to have to worry about updating it manually I just want it to download and install automatically ala Google Chrome. I'm planning on providing an OVF file with Ubuntu and the software installed and configured. My first thought on how to distributed software is to create six Apt repositories/channels (not sure which would be better at this point) that will be accessed through SSH using keys so if a customer doesn't renew their subscription we can disable their account: Beta - Used internally on test data to check the package for major defects. Internal - Used internally on live data to check the package for defects (dog fooding stage). External 1 - Deployed to 1% of our user base (randomly selected) to check for defects. External 9 - Deployed to 9% of our user base (ramdonly selected) to check for defects. External 90 - Deployed to the remaining 90% of users. Hosted - Deployed to the hosted environment. It will take a sign off at each stage to move into the next repository in case problems are reported. My questions to the community are: Has anyone tried something like this before? Can anyone see a downside to this type of a procedure? Is there a better way?

  • What free Remote Desktop (server) solutions are there?

    - by Tao
    I know Ubuntu comes with a "Remote Desktop" option that appears to be a straightforward VNC server, and I'm trying to understand the alternatives. Here are the possibilities I've heard about so far: VNC VNC + SSH Tunnelling NX Server, free edition FreeNX NeatX X2Go X11 Forwarding over SSH xrdp I'm coming at this from a Windows user's perspective: To the best of my experience, RDP (aka Terminal Services) is a reasonably secure (barring mitm/server spoofing), efficient desktop sharing protocol with well-supported clients, that can be exposed to the internet when necessary without major fears of intrusion. To the best of my knowledge straight VNC is none of those things, which is where I get confused - why wouldn't a better desktop sharing technology be developed or used in the open-source world? I know VNC can be wrapped with SSH, but that seems beyond the reach of a casual user. X11 forwarding over SSH may be more or less efficient, I have no idea, but is definitely even more complicated, and doesn't (as far as I know) give you access to already-running stuff (no desktop sharing as such, just remote application running). So, I'd like any feedback/preferences amongst these or any other "Free" desktop sharing options, using these criteria and/or any others: Security (esp. for access across internet) Efficiency (bandwidth usage, responsiveness, etc) Free-ness, as in Speech (not sure where RDP or FreeNX lie for this) Free-ness, as in Beer (are there any commercial solutions with usable dependable free offerings?) Ease of use (server and client side) Cross-OS Client availability Cross-OS Server availability Support for independent sessions and shared (and/or "Console") sessions Ongoing support/maintenance/development Thanks!

  • TFS Build 2010: BuildNumber and DropLocation

    - by javarg
    Automatic Builds for Application Release is a current practice in every major development factory nowadays. Using Team Foundation Server Build 2010 to accomplish this offers many opportunities to improve quality of your releases. The following approach allow us to generate build drop folders including the BuildNumber and the Changeset or Label provided. Using this procedure we can quickly identify the generated binaries in the Drop Server with the corresponding Version. Branch the DefaultTemplate.xaml and renamed it with CustomDefaultTemplate.xaml Open it for edit (check out) Go to the Set Drop Location Activity and edit the DropLocation property. Write the following expression: BuildDetail.DropLocationRoot + "\" + BuildDetail.BuildDefinition.Name + "\" + If(String.IsNullOrWhiteSpace(GetVersion), BuildDetail.SourceGetVersion, GetVersion) + "_" + BuildDetail.BuildNumber Check in the branched template. Now create a build definition named TestBuildForDev using the new template. The previous expression sets the DropLocation with the following format: (ChangesetNumber|LabelName)_BuildName_BuildNumber The first part of the folder name will be the changeset number or the label name (if triggered using labels). Folder names will be generated as following: C1850_TestBuildForDev_20111117.1 (changesets start with letter C) LLabelname_TestBuildForDev_20111117.1 (labels start with letter L) Try launching a build from a Changeset and from a Label. You can specify a Label in the GetVersion parameter in the Queue new Build Wizard, going to the Parameters tab (for labels add the “L” prefix):

  • New Year's Resolutions and Keeping in Touch in 2011

    - by Brian Dayton
    The run-up to Oracle OpenWorld 2010 San Francisco--and the launch of Fusion Applications--was a busy time for many of us working on the applications business at Oracle. The great news was that the Oracle Applications general sessions, sessions, demogrounds and other programs were very well attended and well received. Unfortunately, for this blog, the work wasn't done there. Yes, there haven't been many additional blog entries since the previous one, which one industry analyst told us "That's a good post!" That being said, our New Year's Resolution is to blog more frequently about what's been keeping us busy since Oracle OpenWorld San Francisco. A quick summary: - A 4-part webcast series covering major elements of Oracle's Applications strategy - Oracle OpenWorld Brazil - Oracle OpenWorld China - A stellar fiscal Q2 for Oracle and our applications business - Engagement with many Oracle Fusion Applications Early Adopter customers (more on this in the coming year) Objectives for the Coming Year Looking forward at 2011 there are many ways in which we hope to continue making connections with our valued customers and partners, sharing information about where Oracle Applications are headed, and answering questions about how to manage your Oracle Applications roadmap.

  • Visual WebGui launches a CompanionKit for enhanced developers experience

    - by Webgui
    Visual WebGui launched a new major live demo of the platform's concepts, features and controls and the code behind them. The new Developer CompanionKit is a hige leap forward in the developer experience by allowing developers a hands-on exploration of Visual WebGui which should provide better understanding of the system and the ability to utilize the great advantages of Visual WebGui in order to develop better performing rich web applications. The CompanionKit is available online at companionkit.visualwebgui.com/main.wgx We invite you to Explore Visual WebGui via the new CompanionKit and to watch the CompanionKit Intro video. Below is a screenshot taken from the live CompanionKit which allows developers to see how applying an alternate style to the appearance of a DataGridView is done and how it looks running live and its code (C# or VB.NET). You can access the different Controls (within the Controls section) from the left navigation bar or perform a free text search which shows the relevant results from all the sections - additional sections such as a Concept section are expected to be added in the near future.   In addition, the New Developer CompanionKit which was built with Visual WebGui showcases the enhanced UI design capabilities of building more engaing, modern Web 2.0 applications. The CompanionKit will also be available for download in the next few days as part of the media for 6.4 beta 2 SDK (.NET 2.0 or .NET 3.5) under "Help and Documentation".

  • Google CDN or Akamai

    - by AlienWebguy
    We combine and minify our JS with Minify - the combined JS is then cached on Akamai. I'm suggesting to my supervisor that we put JQuery and JQueryUI on Google CDN and take it out of our combined JS. The benefits I see are parallel downloads, significantly smaller Akamai cache hit, and the high potential the user will have JQuery from Google CDN cached in his/her browser when he/she visits our site so no download will be required at all. I also pointed out how pointing to the major version CDN URL //ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js will eliminate the need for us to micro-manage our JQuery version control, and that if a new release introduces a bug, we simply point the CDN URL to a stable minor version of our choice until the issue is resolved. My supervisor disagrees and thinks keeping it on Akamai is the way to go. Any insight as to which is going to be faster here? I looked for some benchmarks and references online but they are either out-dated or merely talk about Google wanting to acquire Akamai. EDIT: Some further research has pointed me to an article mentioning how 'latest version' CDN URL's use short expires headers so it might be more optimal to use /jquery/1.7/. I'm fine with this - the general question still remains.

  • Bit by bit comparison of using Java or Python for unit testing frameworks and Selenium

    - by Anirudh
    Currently we are in the process of finalizing which language out of Java, Python should be used for Automation using selenium webdriver and a suitable unit testing frameworks. I have made use of Junit, TestNG and webdriver while using with Java and have designed frameworks without much fuss before. I am new to python though I came across pyhton's unit testing frameworks like unittest, pyunit, nose e.t.c but I have doubts if they would be as successful as testNG or Java. I would like to analyze point by point when used with selenium webdriver as below: 1)I have read that as Python is an interpreted language hence it's execution is slower, so say if I have to run 1000 test cases which take about 6 hours to run in Java, would python take considerably longer time for the same test cases like 8 hours? 2)Can the Python unit testing framework be as flexible as a Java unit testing framework like testNG in terms or Grouping the tests, parallel execution, skipping test. e.t.c 3)Also one point that I think of is that Python with selenium webdriver doeasn't have as big or learned community as we have for Java with webdriver, say if I run into trouble with something I am more likely to find an answer for Java as compared to python? 4)Somewhat related to point 3, is it safe to rely on tools, plugins or even webderiver's python's binding as a continuously well maintained? 5)One major drawback as I see while using python's unit testing framework is lack of boilerplate code or libraries for nicely illustrative HTML reports preferably historical reports with Pie charts, bar graphs and timelines as we have in case of Java like Allure, TestNG's default reports, reportNG or Junit reports with the help of ANT as shown below Allure Reports Junit Historical reports Also I would like to emphasize on the fact if there is a way for one to write the framework in java and make libraries or utilities according to out application in webdriver which can easily be called or integrated in with python code or modules? That would actually solve the problem for us as the client would be able to use the code we write in Java and make use of the same or call it from their python modules?

  • 3 Key Trends For Mobile Commerce – Location, Location, Location

    - by Michael Hylton
    This past weekend I was at a major bookstore chain and looking for a particular book.  Rather than ask the clerk, I went to my smartphone and went online to find the book title, author, and competing price.  I know I’m not alone in this effort and more and more individuals (and businesses) will use the power of mobility to tilt the scale in their favor. Armed with a mobile device – smartphone or tablet – folks will use them to research, compare, and ultimately purchase.  A recent PayPal survey found that 46% of respondents plan to use a mobile device this holiday season to make a purchase.   An astounding 27% of consumers in an e-tailing group survey commissioned by Oracle, use a tablet device daily or several times a week to research products and services. Beyond researching or making purchases, 35% of consumers use their smartphone to receive offers and coupons, and 32% access coupons and redeem them at their local retail store.  And with GPS capabilities in smartphones and tablet (and with user’s approval), retailers will start pushing coupons and offers directly to phone users based on their proximity to their store (or their competitors). Security is one concern that both shoppers, companies and phone manufacturers will have to deal with in the coming years.  In that same Oracle-sponsored e-tailing group consumer survey, 32% of consumers were concerned about giving their credit card information via a smartphone. You can gain further insight into the mind of today’s consumer by reading the e-tailing group white paper, titled “the connected consumer”.
