• excel rows,find if include,low and high

  - by Malin Pedersen

  Link to full-size image For what is marked in orange: As mentioned in the example in the picture it says "headphones". I would like it to search through all the lines in column A, to find something that has that name in it, then it should count the number of people, and come out with the number (in how many) the "middle price" I want it to take the price of B (depending on where it found it called headphones) and take the average price of it. In secured, as I would like it to count how many of them (from the number, or from the beginning) that have "secured" as "no" and "yes." I would like to use this on several things. For what is marked in pink: Where would I find the average price of all the goods, and what the name of the particular item is? Same with the highest and lowest price. How can I do this?

• Microeconomical simulation: coordination/planning between self-interested trading agents

  - by Milton Manfried

  In a typical perfect-information strategy game like Chess, an agent can calculate its best move by searching the state tree for the best possible move, while assuming that the opponent will also make the best possible move (i.e. Mini-max). I would like to use this approach in a "game" modeling economic activity, where the possible "moves" would be to buy or sell for a given price, and the goal, rather than a specific class of states (e.g. Checkmate), would be to maximize some function F of the agent's state (e.g. F(money, widget) = 10*money + widget). How to handle buy/sell actions that require coordination between both parties, at the very least agreement upon a price? The cheap way out would be to set the price beforehand, maybe based upon the current supply -- but the idea of this simulation is to examine how prices emerge when freely determined by "perfectly rational" agents. A great example of what I do not want is the trading algorithm in SugarScape -- paraphrasing from Growing Artificial Societies p101-102: when a pair of agents interact to trade, they each compute their internal valuations of the goods, then a bargaining process is conducted and a price is agreed to. If this price makes both agents better off, they complete the transaction The protocol itself is beautiful, but what it cannot capture (as far as I can tell) is the ability for an agent to pay more than it might otherwise for a good, because it knows that it can sell it for even more at a later date -- what appears to be called "strategic thinking" in this pape at Google Books Multi-Agent-Based Simulation III: 4th International Workshop, MABS 2003... to get realistic behavior like that, it seems one would either (1) have to build an outrageously-complex internal valuation system which could at best only cover situations that were planned for at compile-time, or otherwise (2) have some mechanism to search the state tree... which would require some way of planning future trades. Note: The chess analogy only works as far as the state-space search goes; the simulation isn't intended to be "zero sum", so a literal mini-max search wouldn't be appropriate -- and ideally, it should work with more than two agents.

• Showrooming: What's the big deal?

  - by David Dorf

  There's been lots of chatter recently on how retailers will combat showrooming this holiday season.  Best Buy and Target, for example, plan to price-match certain online sites.  But from my perspective, the whole showrooming concept is overblown.  Yes, mobile phones make is easier to comparison-shop, but consumers have been doing that all along.  Retailers have to work hard to merchandise their stores with the right products at the right price with the right promotions.  Its Retail 101. Yeah ok, many websites don't have to charge tax so they have an advantage, but they also have to cover shipping costs. Brick-and-mortar stores have the opportunity to provide expertise, fit, and instant gratification all of which are pretty big advantages. I see lots of studies that claim a large percentage of shoppers are showrooming.  Now I don't do much shopping, but when I do I rarely see anyone scanning UPC codes in the aisles.  If you dig into those studies, the question is usually something like, "have you used your mobile phone to price compare while shopping in the last year."  Well yeah, I did it once -- out of the 20 shopping trips.  And by the way, the in-store price was close enough to just buy the item.  Based on casual observation and informal surveys of friends, showrooming is not the modus-operandi for today's busy shoppers. I never see people showrooming in grocery stores, and most people don't bother for fashion.  For big purchases like appliances and furniture, I bet most people do their research online before entering the store.  The cases where I've done it was to see if a promotion was in fact a good deal.  Or even to make sure the in-store price is the same as the online price for the same brand. So, if you think you're a victim of showrooming, I suggest you look at the bigger picture.  Are you providing an engaging store experience?  Are you allowing customers to shop the way they want to shop, using various touchpoints?  Are you monitoring the competition to ensure prices are competitive?  Are your promotions attracting the right customers? Hubert Jolly, CEO of Best Buy, recently commented that showrooming might just get more people into his stores. "Once customers are in our stores, they're ours to lose."

• PASS Summit 2011: Save Money Now

  - by Bill Graziano

  Register by March 31st and save $200.  On April 1st we increase the price.  On July 1st we increase it again.  We have regular price bumps all the way through to the Summit.  You can save yourself $200 if you register by Thursday. In two years of marketing for PASS and a year of finance I’ve learned a fair bit about our pricing, why we do this and how you react to it.  Let me help you save some money! Price bumps drive registrations.  We see big spikes in the two weeks prior to a price increase.  Having a deadline with a cost attached is a great motivator to get people to take action. Registering early helps you and it helps PASS.  You get the exact same Summit at a cheaper rate.  PASS gets smoother cash flow and a better idea of how many people to expect.  We also get people that are already registered that will tell their friends about the conference. This tiered pricing lets us serve those that are very price conscious.  They can register early and take advantage of these discounts.  I know there are people that pay for this conference out of their own pockets.  This is a great way for those people to reduce the cost of the conference.  (And remember for next year that our cheapest pricing starts right after the Summit and usually goes up around the first of the year.) We also get big price bumps after we announce the program and the pre-conference sessions.  If you wrote down the 50 or so best known speakers in the SQL Server community I’m guessing we’ll have nearly all of them at the conference.  We did last year.  I expect we will this year too.  We’re going to have good sessions.  Why wait?  Register today. If you want to attend a pre-conference session you can always add it to your registration later.  Pre-con prices don’t change.  It’s very easy to update your registration and add a pre-conference session later. I want as many people as possible to attend the Summit.  It’s been a great experience for me and I hope it will be for you.  And if you are going to go, do yourself a favor and save some money.  Register today!

• How to make a dropdown list such that... (see details)

  - by daysandtimes

  I want to plot the stock prices of certain companies VS the S&P500. I have all the price data downloaded in my excel sheet already. I want to create a line graph in Excel. One line is fixed and that would be the S&P500, and the other would be the company I select. I know how to use data validation to create a dropdown list, but how could I make it in such a way that when I select company A, I would only see company A's price data but not company B, C, etc. Then when I select company B, I would only see company B's price data & the S&P price data. And so on. The S&P line will be visible all the time, but the various company's price line will only appear if it is selected. Is there any easy way to normalize all sets of data in a way such that the starting point is always 100?

• Difference between Global and Local SEO

  - by user29660

  I have been reading up on SEO techniques in an effort to learn how to do it thoroughly so I can charge my client for the service. To guage my price I have checked out competitor prices and noticed that theres a fair price difference when it comes to guarenteeing a page 1 ranking with global keywords compared to local keywords. So what is the difference in terms of work load and techniques used to justify this price difference? just to clarify, i am looking for technical differences in programming , methodology etc.

• Magento MAGMI: Product attributes (custom options) not showing up in import

  - by Rodgers and Hammertime

  When importing a CSV into Magento with the MAGMI importing tool, I am unable to import Custom Options (as in size: smalee/medium/large). The import manages to put in the basic products, but the Custom Options don't transfer accross. By custom options I mean the fields Title, Input Type, Is Required, Sort Order Title, Price, Price Type, SKU, Sort Order Title, Price, Price Type, SKU, Sort Order Title, Price, Price Type, SKU, Sort Order and so on ... Found in the custom options menu... Even using the example CSV from the MAGMI SourceForge Wiki: sku,name,description,price,Size:drop_down:1 T-Shirt1,T-Shirt,A T-Shirt,5.00,Small|Medium|Large T-Shirt2,T-Shirt2,Another T-Shirt,6.00,XS|S|M|L|XL ...it fails to import the attributes. So i'm simply using MAGMI with the supplied example data from SourceForge on a blank magento product list, and it doesn't transfer properly. Can anyone shed any light on what might be wrong? I am using Magento ver. 1.6.1.0 if that changes anything. Thanks.

• How to test if raising an event results in a method being called conditional on value of parameters

  - by MattC

  I'm trying to write a unit test that will raise an event on a mock object which my test class is bound to. What I'm keen to test though is that when my test class gets it's eventhandler called it should only call a method on certain values of the eventhandlers parameters. My test seems to pass even if I comment the code that calls ProcessPriceUpdate(price); I'm in VS2005 so no lambdas please :( So... public delegate void PriceUpdateEventHandler(decimal price); public interface IPriceInterface{ event PriceUpdateEventHandler PriceUpdate; } public class TestClass { IPriceInterface priceInterface = null; TestClass(IPriceInterface priceInterface) { this.priceInterface = priceInterface; } public void Init() { priceInterface.PriceUpdate += OnPriceUpdate; } public void OnPriceUpdate(decimal price) { if(price > 0) ProcessPriceUpdate(price); } public void ProcessPriceUpdate(decimal price) { //do something with price } } And my test so far :s public void PriceUpdateEvent() { MockRepository mock = new MockRepository(); IPriceInterface pi = mock.DynamicMock<IPriceInterface>(); TestClass test = new TestClass(pi); decimal prc = 1M; IEventRaiser raiser; using (mock.Record()) { pi.PriceUpdate += null; raiser = LastCall.IgnoreArguments().GetEventRaiser(); Expect.Call(delegate { test.ProcessPriceUpdate(prc); }).Repeat.Once(); } using (mock.Playback()) { test.Init(); raiser.Raise(prc); } }

• Avoiding seasonality assumption for stl() or decompose() in R

  - by user303922

  Hello everybody, I have high frequency commodity price data that I need to analyze. My objective is to not assume any seasonal component and just identify a trend. Here is where I run into problems with R. There are two main functions that I know of to analyze this time series: decompose() and stl(). The problem is that they both take a ts object type with a frequency parameter greater than or equal to 2. Is there some way I can assume a frequency of 1 per unit time and still analyze this time series using R? I'm afraid that if I assume frequency greater than 1 per unit time, and seasonality is calculated using the frequency parameter, then my forecasts are going to depend on that assumption. names(crude.data)=c('Date','Time','Price') names(crude.data) freq = 2 win.graph() plot(crude.data$Time,crude.data$Price, type="l") crude.data$Price = ts(crude.data$Price,frequency=freq) I want frequency to be 1 per unit time but then decompose() and stl() don't work! dim(crude.data$Price) decom = decompose(crude.data$Price) win.graph() plot(decom$random[2:200],type="line") acf(decom$random[freq:length(decom$random-freq)]) Thank you.

• How to order search results by multiple fields?

  - by JustinRoR

  I am using Sunspot and Will_paginate for search in my application and don't how to have my search results start out with certain ordering conditions. The model I am searching is the UserPrice model and want my :price and :purchase_date in descending order or lowest price to highest and present date to past: class UserPrice < ActiveRecord::Base attr_accessible :price, :product_name, :purchase_date belongs_to :product # Sunspot configuration searchable do text :product_name do product.name end end end class SearchController < ApplicationController def index @search = UserPrice.search do fulltext params[:search] paginate(:per_page => 5, :page => params[:page]) end @user_prices = @search.results end end Even though I don't know how, I'm not sure if I would use Sunspot or Will_paginate to sort by order of price and purchase date. How would I achieve this though? Thank you. UPDATE I try to use the order_by method but not sure how the model would look now. class SearchController < ApplicationController def index @search = UserPrice.search do fulltext params[:search] paginate(:per_page => 5, :page => params[:page]) facet(:business_retail_store_id) facet(:business_online_store_id) order_by :price, :desc order_by :purchase_date, :desc end @user_prices = @search.results end end Not sure why having the following in my controller: order_by :price, :desc order_by :purchase_date, :desc I get the error: Sunspot::UnrecognizedFieldError in SearchController#index No field configured for UserPrice with name 'price' This doesn't make sense to me since I do have these fields inside of my UserPrice model and in my database. How do I fix this?

• mysql query not running correctly from inside the application

  - by Mala

  I am completely stumped. Here is my php (CodeIgniter) code: function mod() { $uid = $this->session->userdata('uid'); $pid = $this->input->post('pid'); if ($this->_verify($uid,$pid)) { $name = $this->input->post('name'); $price = $this->input->post('price'); $curr = $this->input->post('curr'); $url = $this->input->post('url'); $query = $this->db->query("UPDATE items SET name=".$this->db->escape($name).", price=".$this->db->escape($price).", currency=".$this->db->escape($curr),", url=".$this->db->escape($url)." WHERE pid=".$this->db->escape($pid)." LIMIT 1"); } header('location: '.$this->session->userdata('current')); } The purpose of this code is to modify the properties (name, price, currency, url) of a row in the 'items' table (priary key is pid). However, for some reason, allowing this function to run once modifies the name, price, currency and url of ALL entries in the table, regardless of their pid and of the LIMIT 1 thing I tacked on the end of the query. It's as if the last line of the query is being completely ignored. As if this wasn't strance enough, I replaced "$query = $this->db->query(" with an "echo" to see the SQL query being run, and it outputs a query much like I would expect: UPDATE items SET name='newname', price='newprice', currency='newcurrency', url='newurl' WHERE pid='10' LIMIT 1 Copy-pasting this into a MySQL window acts exactly as I want: it modifies the row with the selected pid. What is going on here???

• Copy existing XML, duplicate element and modify

  - by Robert

  Hi, I have a tricky XSL problem at the moment. I need to copy the existing XML, copy a certain element (plus its child elements) and modify the value of two child-elements. The modifications are: divide value of the 'value' element by 110 and edit the value of the 'type' element from 'normal' to 'discount'. This is currently what I have: Current XML: <dataset> <data> <prices> <price> <value>50.00</value> <type>normal</type> </price> </prices> </data> </dataset> Expected result <dataset> <data> <prices> <price> <value>50.00</value> <type>normal</type> </price> <price> <value>45.00</value> <type>discount</type> </price> </prices> </data> </dataset> Any takers? I've gotten as far as copying the desired 'price' element using copy-of, but I'm stuck as to how to modify it next.

• How do I compare 2 fields and return the lowest value of each record?

  - by BigRob

  I'm slowly learning access to make a database of products and suppliers for my parents' business. What i've got is a table of products indexed by our product reference and 2 more tables for 2 different suppliers that contains the suppliers product reference and price that links with our reference. I've made a query that performs a left outer join such that it returns a table of our products with each supplier's reference and price, i.e: Ref | Product Name | Supplier 1 Ref | Supplier 1 Price | Supplier 2 Ref | Supplier 2 Price Here's the query I used: SELECT Catalog.Ref, Catalog.[Product Name], Catalog.Price, [D Products].[Supplier Ref], [D Products].Cost, [GS Products].[Supplier Ref], [GS Products].Cost FROM ([Catalog] LEFT JOIN [D Products] ON Catalog.Ref = [D Products].Ref) LEFT JOIN [GS Products] ON Catalog.Ref = [GS Products].Ref; Not all products are available from both suppliers, hence the outer join. What I want to do (with a query?) is to take the table produced by the query above and simply show the product reference, cheapest supplier reference and cheapest supplier price, i.e: Ref | Cheapest Suppplier Ref | Cheapest Supplier Price Unfortunately my SQL knowledge isn't quite good enough to figure this out, but if anyone can help i'd really appreciate it. Thanks, Rob

• JavaOne Tutorial Report - JavaFX 2 – A Java Developer’s Guide

  - by Janice J. Heiss

  Oracle Java Technology Evangelist Stephen Chin and Independent Consultant Peter Pilgrim presented a tutorial session intended to help developers get a handle on JavaFX 2. Stephen Chin, a Java Champion, is co-author of the Pro JavaFX Platform 2, while Java Champion Peter Pilgrim is an independent consultant who works out of London.NightHacking with Stephen ChinBefore discussing the tutorial, a note about Chin’s “NightHacking Tour,” wherein from 10/29/12 to 11/11/12, he will be traveling across Europe via motorcycle stopping at JUGs and interviewing Java developers and offering live video streaming of the journey. As he says, “Along the way, I will visit user groups, interviewing interesting folks, and hack on open source projects. The last stop will be the Devoxx conference in Belgium.”It’s a dirty job but someone’s got to do it. His trip will take him from the UK through the Netherlands, Germany, Switzerland, Italy, France, and finally to Devoxx in Belgium. He has interviews lined up with Ben Evans, Trisha Gee, Stephen Coulebourne, Martijn Verburg, Simon Ritter, Bert Ertman, Tony Epple, Adam Bien, Michael Hutterman, Sven Reimers, Andres Almiray, Gerrit Grunewald, Bertrand Boetzmann, Luc Duponcheel, Stephen Janssen, Cheryl Miller, and Andrew Phillips. If you expect to be in Chin’s vicinity at the end of October and in early November, by all means get in touch with him at his site and add your perspective. The more the merrier! Taking the JavaFX PlungeNow to the business at hand. The “JavaFX 2 – A Java Developer’s Guide” tutorial introduced Java developers to the JavaFX 2 platform from the perspective of seasoned Java developers. It demonstrated the breadth of the JavaFX APIs through examples that are built out in the course of the session in an effort to present the basic requirements in using JavaFX to build rich internet applications. Chin began with a quote from Oracle’s Christopher Oliver, the creator of F3, the original version of JavaFX, on the importance of GUIs:“At the end of the day, on the one hand we have computer systems, and on the other, people. Connecting them together, and allowing people to interact with computer systems in a compelling way, requires graphical user interfaces.”Chin explained that JavaFX is about producing an immersive application experience that involves cross-platform animation, video and charting. It can integrate Java, JavaScript and HTML in the same application. The new graphics stack takes advantage of hardware acceleration for 2D and 3D applications. In addition, we can integrate Swing applications using JFXPanel.He reminded attendees that they were building JavaFX apps using pure Java APIs that included builders for declarative construction; in addition, alternative languages can be used for simpler UI creation. In addition, developers can call upon alternative languages such as GroovyFX, ScalaFX and Visage, if they want simpler UI creation. He presented the fundamentals of JavaFX 2.0: properties, lists and binding and then explored primitive, object and FX list collection properties. Properties in JavaFX are observable, lazy and type safe. He then provided an example of property declaration in code.  Pilgrim and Chin explained the architectural structure of JavaFX 2 and its basic properties:JavaFX 2.0 properties – Primitive, Object, and FX List Collection properties. * Primitive Properties* Object Properties* FX List Collection Properties* Properties are:– Observable– Lazy– Type SafeChin and Pilgrim then took attendees through several participatory demos and got deep into the weeds of the code for the two-hour session. At the end, everyone knew a lot more about the inner workings of JavaFX 2.0.

• Oracle: Addressing Information Overload in Factory Automation

  - by [email protected]

   ORACLE's Stephen Slade has written about addressing information overload on the factory floor.  According to Slade, today's automated processes create large amounts of valuable data, but only a small percentage remains actionable.Oracle claims information overload can cost financially, as companies struggle to store and collect reams of data needed to identify embedded trends, while producing manual reports to meet quality standards, regulatory requirements and general reporting goals.Increasing scrutiny of new requirements and standards add to the need to find new ways to process data. Many companies are now using analytical engines to contextualise data into 'actionable information'. Oracle claims factories need to seriously address their data collection, audit trail and records retention processes. By organising their data, factories can maximise outcomes from excellence and contuinuous improvement programs, and gain visibility into costs int the supply chain.Analytics tools and technologies such as Business Intelligence (BI), Enterprise Manufacturing Intelligence (EMI) and Manufacturing Operations Centers (MOC) can help consolidate, contextual and distribute information.   FULL ARICLE:  http://www.myfen.com.au/news/oracle--addressing-information-overload-in-factory

• Why does my cursor jump when typing in ubuntu 11.10

  - by Stephen Myall

  When typing in Ubuntu my cursor jumps around and its not application specific. It doesn't matter or Im filing in a web form, writing an e-mail or using LibreOffice or Lyx. Im using a Sony Vaio 64bit machine. i read a previous question (link below) on this subject which indicates it may have something to do with the touchpad settings. as this has occurred in previous Ubuntu distros Im guess it is somekind of hardware issue. How do you turn of the touchpad when typing to avoid the cursor jumping around? I'd be grateful if anyone can make this stop Stephen

• Insert <div> outside every three <li>

  Hello.

I know that this is not semantic and not right, but this is only for example. (Basically if I will figure put how to do this, I will replace li's on spans and that div that i need outside li's on li). Will be very glad if someone will help me. Because code that I have is already too much for me.

• Why do AWS spot-instance prices spike above the "on demand" pricing?

  - by Laykes

  Amazon Pricing on Spot Instance Inconsistencies This is something which will be best explained through screenshots of a historical chart of instance pricings. If you look at a lot of the instance prices for spot instances, you will notice regular patterns of spikes. See here: As you can see, the price for this compute medium instance, regularly spikes above the on demand price. A c1.medium instance (on demand), would only cost $0.186 per hour. But for a period of a few weeks, in zone B, the price would regularly spike to $1.20. This is some 6 times the actual on demand price. It's also not isolated. If you look at zone-b again for small instances, there is a similar, spike frequently. Which goes 4x the on demand pricing. Does anyone know why this happens? Here are a few suggestions Someone entered $1.2 instead of $0.12 (I would discount this since it happened 20 times over the space of 3 weeks). Amazon regularly artifically inflate their prices by bidding on their own instances to get the most bang for their buck. (I would discount this since it would be ridiculous and bad business) Some company launched 1000 servers at once, and wants to make sure that they all launch. (I would discount this since they would presumably launch them at a price which would be below the minimum on demand price. Why would you pay above on demand for a single server?). It's a bug in their reporting?

• Pages load in brower fine, but 404 not found reported for the page during the GET on all pages except index

  - by user885983

  I believe this question is more suited to serverfault (please correct me if not). This issue appears very similar to this question (except there are no 301 Moved Permanently for any pages). The domain is yorkshirebadges.co.uk. For example, loading yorkshirebadges.co.uk or yorkshirebadges.co.uk/index.php reports no 404s during network inspection. But every other page (/contact.php, /products.php) report a not found. Mod_rewrite is being used on the site, I checked this out but didn't see any obvious errors. It's included below for reference: RewriteEngine on RewriteRule ^store/material/([^/\.]+)/price/?([^/\.]+)?$ products.php?prodType=$1&price=$2 RewriteRule ^store/price/?([^/\.]+)?$ products.php?price=$1; RewriteRule ^store/material/?([^/\.]+)?$ products.php?prodType=$1 RewriteRule ^store/([^/\.]+)/?$ products.php?prodCat=$1 RewriteRule ^store/([^/\.]+)/price/([^/\.]+)$ products.php?prodCat=$1&price=$2 RewriteRule ^store/Type/?([^/\.]+) products.php?prodType=$1 RewriteRule ^store/([^/\.]+)/?([^/\.]+)?$ view-product-details.php?cat=$1&prodName=$2 RewriteRule ^store/([^/\.]+)/material/?([^/\.]+)?$ products.php?prodCat=$1&prodType=$2 RewriteRule analytics http://www.google.com/analytics <IfModule mod_suphp.c> suPHP_ConfigPath /home/yorkshir <Files php.ini> order allow,deny deny from all </Files> </IfModule> Chrome Network Inspection (and firebug on firefox) report 404s on all pages except the index, the server is apache2. Really scratching my head on this one!

• How to prevent 2D camera rotation if it would violate the bounds of the camera?

  - by Andrew Price

  I'm working on a Camera class and I have a rectangle field named Bounds that determines the bounds of the camera. I have it working for zooming and moving the camera so that the camera cannot exit its bounds. However, I'm a bit confused on how to do the same for rotation. Currently I allow rotating of the camera's Z-axis. However, if sufficiently zoomed out, upon rotating the camera, areas of the screen outside the camera's bounds can be shown. I'd like to deny the rotation assuming it meant that the newly rotated camera would expose areas outside the camera's bounds, but I'm not quite sure how. I'm still new to Matrix and Vector math and I'm not quite sure how to model if the newly rotated camera sees outside of its bounds, undo the rotation. Here's an image showing the problem: http://i.stack.imgur.com/NqprC.png The red is out of bounds and as a result, the camera should never be allowed to rotate itself like this. This seems like it would be a problem with all rotated values, but this is not the case when the camera is zoomed in enough. Here are the current member variables for the Camera class: private Vector2 _position = Vector2.Zero; private Vector2 _origin = Vector2.Zero; private Rectangle? _bounds = Rectangle.Empty; private float _rotation = 0.0f; private float _zoom = 1.0f; Is this possible to do? If so, could someone give me some guidance on how to accomplish this? Thanks. EDIT: I forgot to mention I am using a transformation matrix style camera that I input in to SpriteBatch.Begin. I am using the same transformation matrix from this tutorial.
