  • The Retail Week Conference 2012 - Interview with Paul Dickson

    - by user801960
    Recently we attended the Retail Week Conference at the Hilton London Metropole Hotel in London. The conference proves to be an inspirational meeting of retail minds and the insight gained from both the speakers and the other delegates is invaluable. In particular we enjoyed hearing from Charlie Mayfield, Chairman at John Lewis Partnership, about understanding how the consumer is viewing the ever changing world of retail; a session on how to encourage brand-loyal multichannel activities from Robin Terrell of House of Fraser with Alan White of the N Brown Group, Vince Russell from The Cloud and Lucy Neville-Rolfe from Tesco; and a fascinating session from Tim Steiner, Chief Executive of Ocado, about how the business makes it as easy as possible for consumers to shop on their various platforms, which included some surprising usage statistics. Oracle's own Vice President of Retail, Paul Dickson, also held a session with Richard Pennycook, Group Finance Director at Morrisons, about the role of technology in accelerating and supporting the business strategy. Morrisons' 'Evolve' programme takes a litte-and-often approach to updating its technology infrastructure to spread cost and keep the adoption process gentle for staff, and the session explored how the process works and how Oracle's technology underpins the programme to optimise their operations using actionable insight. We had a quick chat with Paul Dickson at the session to get his thoughts on the programme - the video is below. We also filmed the whole presentation, so keep checking back on this blog if you're interested in seeing it.

  • connecting two routers

    - by lee
    I have two routers, both wireless, that i wish to connect together. As it stands Router A is connected via a micro filter into the phone line which i access the web wirelessly. What I want to achieve is to connect Router B to A so I can hardwire My TV and Sky (cable) Box into B and simultaneously browse the web wirelessly via router A. Is this possible? If so I'd appreciate the help on this one to save me running 50ft cable under the carpet!!! PS I'm using Mac OS.

  • Program to set time on local computer using GPS data

    - by dmkerr
    I have a laptop running Windows XP that does not connect to the Internet and I would like to use a USB GPS receiver as a time source to set the clock. Generally, the laptop will not have access to the open sky so getting a strong, multi-satellite connection is not likely. Ideally, I would like to be able to have the program detect the GPS receiver and set the clock without intervention from the user. Is what I'm seeking even feasible?

    - by Jenni
    My laptop connects via a wire into the modem fine and it works without any problems but it wont connect to it wirelessly, when I've taken it out places it connects fine in wifi area's!

  • How do I watch youtube on my TV using a netbook?

    - by couchpotato
    I'm based in the UK. I'd like to watch iplayer, 4od, youtube etc on my TV. I've looked at the Roku box, but as far as I can gather this doesn't support youtube or 4od. I don't have cable in my area and don't want to go with Sky. What options do I have, if any? UPDATE My TV has an HDMI connection. If a netbook is the best or only way to do this, which one would you recommend for connecting to my TV?

  • WYSIHAT 'resonds_to_parent" undefined method - Ruby on Rails

    - by bgadoci
    I just successfully installed WysiHat in my rails blog. Seems that the 'add a picture' feature is not working. It successfully allows me to find and select a picture from my desktop but upon clicking save, it does nothing. I also have Paperclip successfully installed and can attach images to records outside the WYSIHAT form field. Any ideas? (let me know if I need to post any code). Also, WysiHat-engine uses facebox, not sure if that is relevant. UPDATE: Added Server Log, looks like paperclip is saving it so not sure what else is going wrong.

  • jQuery tabs error when used with jTemplates

    - by tessa
    I am using jTemplates to format data returned from a json query. I am trying to transform the div with the id "fundingDialogTabs" into jQuery tabs after the template is processed. It renders the tab buttons, but both fragment1 and fragment2 divs are showing at the same time. I get the error "jQuery UI Tabs: Mismatching fragment identifier" when clicking on the fragment2 tab. I tested the jQuery tabs code outside of the template and it works fine. Here is the template (saved in .tpl file). {#template MAIN} <div style="width:500px"> <table border="0" cellpadding="0" cellspacing="0" id="fundingDialogTitle"> <tr> <td class="fundingDialogTitle">Funding Breakout</td> <td style="text-align:right"><img src="../../images/fscaClose.gif" onclick="CloseFundingDialog()" style="cursor:hand; width:25px; height:25px;"></td> </tr> </table> </div> <div style="padding:10px 10px 10px 10px; width:500px"> <div id="fundingDialogTabs"> <ul> <li><a href="#fragment1"><span>Source</span></a></li> <li><a href="#fragment2"><span>Line Item</span></a></li> </ul> <div id="fragment1"> <table border="0" cellpadding="0" cellspacing="0" id="fundingDialog"> <tr> <th>Funding Source</th> <th>Amount</th> </tr> {#foreach $T.d as fundingList} {#include ROW root=$T.fundingList} {#/for} </table> </div> <div id="fragment2"> Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.

  • Need help choosing between Grails and Yii Framework

    - by user530207
    I recently started on developing in PHP with the Yii Framework. I recently came across the Grails Framework and I'm pretty impressed by the sites they make, bigger companies seem to use Grails for their web development. When looking at yii, not many big companies are using it. I'm just starting out with the Yii framework and I don't want to turn back halfway when in the middle of learning Yii, so I hope someone can give me some comparison about the 2 in terms of power. Does Grails make things much easier and benefit me in the long run? I only have C++ background for now. It boils down to this. I want a powerful framework which will serve me for a very long time and by looking at the number of big companies using Grails, I feel discouraged to take the Yii path. Thank you! Some sites by Grails: http://video.sky.com/ http://espn.go.com/ http://www.atlassian.com/ http://www.linkedin.com/

  • Camera changes view when controller connected

    - by ChocoMan
    I have a weird situation. I have a model set to 0 for X,Y and Z. My camera's position is set to: 0 (X-value, but updates when the model moves around) the model's height + 20f (about the same level as the model's shoulders) 25f (behind the model) Without the controller plugged in, everything looks fine as I want it. But as soon as I plug the controller in, the camera aims to the sky! But when I unplug the controller, the camera is back to what it should be. Does anyone have any insight as to what may cause this from plugging a controller in?

  • The best tile based level design [on hold]

    - by ReallyGoodPie
    My current method for tile based levels is to put everything in an array like the following: grass = g sky = s house = h ... """ ["SSSSSSSSSSSSSSSSSSSSSSSSSSSSSS"], ["SSSSSSSSSSSSSSSSSSSSSSSSSSSSSS"], ["HHHHHHHHHHHHHHSSSSSSSSSSSSSSSS"], ["GGGGGGGGGGGGGGGGGGGGGGGGGGGGGG"], """ I would then run a for loop to pass these on to a sprite class, bliting the images to the screen. This is what I'd generally do in pygame when I am creating levels for a tile based RPG's. However, as I've gone on, I have added allot more sprites and image and it is seriously becoming more and more confusing to work with this and allot of mistakes are being made. What is the best alternative or other methods for doing this?

  • How to move Objects smoothly like swimming arround

    - by philipp
    I have a Box2D project that is about to create a view where the user looks from the Sky onto Water. Or perhaps on a bathtub filled with water or something like this. The Object which holds the fluid actually does not matter, what matters is the movement of the bodies, because they should move like drops of grease on a soup, or wood on water, I can even imagine the the fluid is mercurial, extreme heavy and "lazy". How can I manipulate the bodies (every frame or time by time) to make them move like this? I started with randomly manipulation their linear velocity, but I turned out that this not very smooth and looks quite hard. Is it a better idea to check their velocity and apply impulses? Is there any example? Greetings philipp

  • Variable declaration versus assignment syntax

    - by rwallace
    Working on a statically typed language with type inference and streamlined syntax, and need to make final decision about syntax for variable declaration versus assignment. Specifically I'm trying to choose between: // Option 1. Create new local variable with :=, assign with = foo := 1 foo = 2 // Option 2. Create new local variable with =, assign with := foo = 1 foo := 2 Creating functions will use = regardless: // Indentation delimits blocks square x = x * x And assignment to compound objects will do likewise: sky.color = blue a[i] = 0 Which of options 1 or 2 would people find most convenient/least surprising/otherwise best?

  • 3D BSP rendering for maps made in 2d platform style

    - by Dev Joy
    I wish to render a 3D map which is always seen from top, camera is in sky and always looking at earth. Sample of a floor layout: I don't think I need complex structures like BSP trees to render them. I mean I can divide the map in grids and render them like done in 2D platform games. I just want to know if this is a good idea and what may go wrong if I don't choose a BSP tree rendering here. Please also mention is any better known rendering techniques are available for such situations.

    Facebook est désormais valorisé à 50 milliards de dollars, et dépasse Yahoo, eBay et Time Warner La valeur de Facebook vient de faire un grand bond en avant, malgré que la firme ne soit toujours pas présente en bourse du fait des réticences de son fondateur.

  • OpenGL ES 2. How do I Create a Basic Fading Streak Effect?

    - by dugla
    For the iPad app I am writing using OpenGL ES 2 I have a single quad - shaded using GLSL - that is dragged around the screen. Very basic. This works fine. But is rather boring. I want to increase the coolness a bit in the following way: when the user drags the quad it leaves a streak behind that fades over time. Continuous dragging would be a bit like a streaking comet across the night sky. What is the simplest way to implement this? Thanks.

    I have a cron job which runs a script to unrar all files in a certain directory (/rared for argument's sake) and place the expanded files in /unrared. I would like to change this script so that it deletes the original rar archives from /rared only if they successfully extracted. This does not mean that unrar has reported that they have been fully extracted, because I have had data corruption during decompression before. Ideally (pie-in-the-sky, just to give you an idea of what I'm shooting for,) the unrar program would include this functionality, comparing an expected md5sum value with the actual md5sum value and only deleting the archive if they match. I don't mind scripting this entire process if I have to, but there must be a better way than unraring twice and comparing md5sums.
