  • Android Layout + Programming

    - by MD
    I'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now. The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application. Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through. I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful. Thanks in advance.

I want to create simple console application. It turns out to be a problem. I have simple standard hello world project. I have created it using New Project - Empty project. I added main.cpp that contains this: #include <iostream> using namespace std; int main() { cout << "howdy\n"; } I added new configuration to the project by clicking on Config Manager and added x64 config. Compiled and it compiles. Tried running it and cmd.exe shoots up with following error: "The application has failed to start because its side-by-side configuration is in correct.

  • stored procedure issue, has to do with my where clause and if statement

    - by MyHeadHurts
    right now my stored procedure is returning 2 different result sets one for @booked and the other for @booked1 if you look closely my query is doing the same thing for each @booked and @booked but one is for a user selected year and the other for the current year. I don't want two different result sets, i want to join the selected year and the current year side by side by SDESCR(which is a column that they have in common) another hurdle i am facing is i am use @mode to decide whether the user wants netsales, sales... so on. I know i need sometype of join but, it isnt working because i have a where statement that says where dyyyy= @yeartoget which won't allow the current year data to work ALTER PROCEDURE [dbo].[test1] @mode varchar(20), @YearToGet int AS SET NOCOUNT ON Declare @Booked Int Set @Booked = CONVERT(int,DateAdd(year, @YearToGet - Year(getdate() + 1), DateAdd(day, DateDiff(day, 1, getdate()), 1) ) ) Declare @Booked1 Int Set @Booked1 = CONVERT(int,DateAdd(year, (year( getdate() )) - Year(getdate() + 1), DateAdd(day, DateDiff(day, 1, getdate()), 1) ) ) If @mode = 'Sales' Select Division, SDESCR, DYYYY, Sum(Case When Booked <= @Booked Then NetAmount End) ASofNetSales, SUM(NetAmount) AS YENetSales, Sum(Case When Booked <= @Booked Then PARTY End) AS ASofPAX, SUM(PARTY) AS YEPAX From dbo.B101BookingsDetails Where DYYYY = @YearToGet Group By SDESCR, DYYYY, Division Order By Division, SDESCR, DYYYY else if @mode = 'netsales' Select Division, SDESCR, DYYYY, Sum(Case When Booked <= @Booked Then NetAmount End) ASofNetSales, SUM(NetAmount) AS YENetSales, Sum(Case When Booked <= @Booked Then PARTY End) AS ASofPAX, SUM(PARTY) AS YEPAX From dbo.B101BookingsDetails Where DYYYY = @YearToGet Group By SDESCR, DYYYY, Division Order By Division, SDESCR, DYYYY If @mode = 'Sales' Select Division, SDESCR, DYYYY, Sum(Case When Booked <= @Booked1 Then NetAmount End) currentNetSales, Sum(Case When Booked <= @Booked1 Then PARTY End) AS currentPAX From dbo.B101BookingsDetails Where DYYYY = (year( getdate() )) Group By SDESCR, DYYYY, Division Order By Division, SDESCR, DYYYY else if @mode = 'netsales' Select Division, SDESCR, DYYYY, Sum(Case When Booked <= @Booked1 Then NetAmount End) currentNetSales, Sum(Case When Booked <= @Booked1 Then PARTY End) AS currentPAX From dbo.B101BookingsDetails Where DYYYY = (year( getdate() )) Group By SDESCR, DYYYY, Division Order By Division, SDESCR, DYYYY Else if @mode = 'Inssales' Select Division, SDESCR, DYYYY, Sum(Case When Booked <= @Booked1 Then InsAmount End) currentInsSales, Sum(Case When Booked <= @Booked1 Then PARTY End) AS currentPAX From dbo.B101BookingsDetails Where DYYYY = (year( getdate() )) Group By SDESCR, DYYYY, Division Order By Division, SDESCR, DYYYY

  • Strange JPA one-to-many behavior when trying to set the "many" on the "one" entity

    - by errr
    I've mapped two entities using JPA (specifically Hibernate). Those entities have a one-to-many relationship (I've simplified for presentation): @Entity public class A { @ManyToOne public B getB() { return b; } } @Entity public Class B { @OneToMany(mappedBy="b") public Set<A> getAs() { return as; } } Now, I'm trying to create a relationship between two instances of these entities by using the setter of the one-side/not-owner-side of the relationship (i.e the table being referenced to): em.getTransaction().begin(); A a = new A(); B b = new B(); Set<A> as = new HashSet<A>(); as.add(a); b.setAs(as); em.persist(a); em.persist(b); em.getTransaction().commit(); But then, the relationship isn't persisted to the DB (the row created for entity A isn't referencing the row created for entity B). Why is it so? I'd excpect it to work. Also, if I remove the "mappedBy" property from the @OneToMany annotation it will work. Again - why is it so? and what are the possible effects for removing the "mappedBy" property?

  • How do I produce a screenshot of a flash swf on the server?

    - by indignant
    I'm writing a flash app using the open source tools. I would like to load a data file in to the app and capture a screenshot of the stage on the server. The only part that seems mysterious is running the app on the server. In fact, I don't even care if it's the same app running on the server and in the browser--if I can use the flash stage and drawing routines to produce an image server-side, I'm happy. If I have to delve in to flex, fine. Right now I'm having problems finding any starting point at all. I gather Adobe has some commercial products that may fit the bill, but I'd like to stick with open source, apache, and linux. I know this is probably possible with haxe/neko, but I'd like to use more mainstream tools if possible. Am I asking too much? EDIT/CLARIFICATION: Many thanks for the responses so far, but I think I've been a bit muddy in my description. I've already written the actual stage-grabbing stuff using the same PNGEncoder class as was suggested. The problem is in actually running the swf on the server side. I don't want to let the client take the screen shot itself, because this opens up the possibility of the client maliciously submitting a screenshot which does not correspond to what is on the stage, that is, I don't want users uploading porn. If I could run the the actionscript code on the server, then I could generate the screenshot from my data files and be sure that the screenshot matches the data, but I have no idea how to run the actionscript or swf on the server.

  • JQuery: how to store records id for data from ajax query in dynamicly created html elements

    - by grapkulec
    Probably question title is rather cryptic but I will try to explain myself here so please bare with me :) Let's assume this configuration: server-side is PHP application responding for requests with data (list of items, single item details, etc.) in json format client-side is JQuery application sending ajax request to that PHP app and creating html content corresponding with received data So, for example: client requests "list of all animals with names staring with 'A'", gets the json response from server, and for every "animal" creates some html gizmo like div with animal description or something like that. It doesn't really matter what html element it will be but it has to point exactly to specific record by "containing" id of that record. And here is my dilemma: is it good solution to use "id" property for that? So it would be like: <div id="10" class="animal"> <p> This is animal of very mysterious kind... </p> </div> <div id="11" class="animal"> <p> And this one is very common to our country... </p> </div> where id="10" is of course indication that this is representation of record with id = 10. Or maybe I should store this record id in some custom made tag like <record_id>10</record_id> and leave an "id" strictly for what it was meant to be (css selector)? I need that record id for further stuff like updating database with some user input or deleting some of "animals" or creating new ones or anything that will be needed. All manipulations will be done with JQuery and ajax requests and responses will be visualized also with dynamic creation of html interface. I'm sure that somebody had to deal with that kind of stuff before so I would be grateful for some tips on that topic.

  • algorithm - How to sort a 0/1 array with 2n/3 comparisons?

    - by Jackson Tale
    In Algorithm Design Manual, there is such an excise 4-26 Consider the problem of sorting a sequence of n 0’s and 1’s using comparisons. For each comparison of two values x and y, the algorithm learns which of x < y, x = y, or x y holds. (a) Give an algorithm to sort in n - 1 comparisons in the worst case. Show that your algorithm is optimal. (b) Give an algorithm to sort in 2n/3 comparisons in the average case (assuming each of the n inputs is 0 or 1 with equal probability). Show that your algorithm is optimal. For (a), I think it is fairly easy. I can choose a[n-1] as pivot, then do something like in quicksort partition, scan 0 to n - 2, find the middle point where left side is all 0 and right side is all 1, this take n - 1 comparisons. But for (b), I can't get a clue. It says "each of the n inputs is 0 or 1 with equal probability", so I guess I can assume the numbers of 0 and 1 equal? But how can I get a result which is related to 1/3? divide the whole array into 3 groups? Thanks

  • Creating DOM elements on the fly - check if the data is not harmful

    - by user313353
    I already posted a question closely related to the this one. I watched the Mix10 video with P. Haacked and S. Hanselman. I am building an AJAX-powered site whose input forms are created on the fly. All the code to accomplish this is done within a script tag or a javascript file. For example the following DOM elements are created when the page loads and are wrapped into an existing div defined in a view: $('#myform').append('); $('#myform').append(''); When I click the submit button I need to get the values of the input form whose id is 'Name': $("#Name").val() and then I return a Json object: { Name: name }; For this kind of scenario there is no way to use Html.Encode() or AntiXss.HtmlEncode() on the client-side. The only way to check if the input is not harmful is done on the server-side (via a service layer). This seems a limitation. All is fine if and only if a view has a set of predefined inputs. When it is time to create them on the fly, the situation is different. Have you thought of that situation guys? Thanks for the attention you have put on this. Roland Brussels, Belgium

  • Passing javascript object to webservice via Jquery ajax

    - by kralco626
    I have a webservice that returns an object [WebMethod] public List<User> ContractorApprovals() I also have a webservice that accepcts an object [WebMethod] public bool SaveContractor(Object u) When I make my webservice calls via Jquery: function ServiceCall(method, parameters, onSucess, onFailure) { var parms = "{" + (($.isArray(parameters)) ? parameters.join(',') : parameters) + "}"; // to json $.ajax({ type: "POST", url: "services/"+method, data: parms, contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { if (typeof onSucess == 'function' || typeof onSucess == 'object') onSucess(msg.d); }, error: function(msg, err) { $("#dialog-error").dialog('open');} }); I can call the first one just fine. My onSucess function gets passed a javascript object exactly structured like my User object on the service. However, I am now having trouble getting the object back to the server. I'm accepting Object as a parameter on the server side so I can't inagine there is an issue there. So I'm thinking something is wrong with the parms on the client side but i'm not sure what... I am doing something to the effect ServiceCall("AuthorizationManagerWorkManagement.asmx/ContractorApprovals", "", function(data,args){$("#div").data('user',data[0])}, null) then ServiceCall("AuthorizationManagerWorkManagement.asmx/SaveContractor", $("#div").data('user'), //These also do not work: "{'u': ' + $("#div").data("user") + '}", NOR JSON.stringify({u: userObject}) function(data,args){(alert(data)}, null) I know the first service call works, I can get the data. The second one is causing the "onFailure" method to execute rather then "OnSuccess". Any ideas?

  • How to properly load HTML data from third party website using MVC+AJAX?

    - by Dmitry
    I'm building ASP.NET MVC2 website that lets users store and analyze data about goods found on various online trade sites. When user is filling a form to create or edit an item, he should have a button "Import data" that automatically fills some fields based on data from third party website. The question is: what should this button do under the hood? I see at least 2 possible solutions. First. Do the import on client side using AJAX+jQuery load method. I tried it in IE8 and received browser warning popup about insecure script actions. Of course, it is completely unacceptable. Second. Add method ImportData(string URL) to ItemController class. It is called via AJAX, does the import + data processing server-side and returns JSON-d result to client. I tried it and received server exception (503) Server unavailable when loading HTML data into XMLDocument. Also I have a feeling that dealing with not well-formed HTML (missing closing tags, etc.) will be a huge pain. Any ideas how to parse such HTML documents?

  • What Getters and Setters should and shouldn't do.

    - by cyclotis04
    I've run into a lot of differing opinions on Getters and Setters lately, so I figured I should make it into it's own question. A previous question of mine received an immediate comment (later deleted) that stated setters shouldn't have any side effects, and a SetProperty method would be a better choice. Indeed, this seems to be Microsoft's opinion as well. However, their properties often raise events, such as Resized when a form's Width or Height property is set. OwenP also states "you shouldn't let a property throw exceptions, properties shouldn't have side effects, order shouldn't matter, and properties should return relatively quickly." Yet Michael Stum states that exceptions should be thrown while validating data within a setter. If your setter doesn't throw an exception, how could you effectively validate data, as so many of the answers to this question suggest? What about when you need to raise an event, like nearly all of Microsoft's Control's do? Aren't you then at the mercy of whomever subscribed to your event? If their handler performs a massive amount of information, or throws an error itself, what happens to your setter? Finally, what about lazy loading within the getter? This too could violate the previous guidelines. What is acceptable to place in a getter or setter, and what should be kept in only accessor methods?

  • How to develop Online Shopping Portal Application using PHP ?

    - by Sarang
    I do not know PHP & I have to develop a Shopping Portal with following Definition : Scenario: Online Shopping Portal XYZ.com wants to create an online shopping portal for managing its registered customers and their shopping. The customers need to register themselves first before they do shopping using the shopping portal. However, everyone, whether registered or not, can view the various products along with the prices listed in the portal. The registered customers, after logging in, are allowed to place order for one or more products from the products listed in the portal. Once the order is placed, the customer gets a reference order number and the order status should be “order in process”. The customers can track their order using the given reference number. The management of XYZ.com should be able to modify the order status of a particular reference order number to “shipped” once the products are shipped to the shipping address entered by the customer at the time of placing the order. The Functionalities required are : Create the interface for the XYZ.com shopping portal using HTML/XHTML and CSS. Implement the client side validations using JavaScript. Create the tables using MySQL. Implement the functionality using the server side scripting language, PHP. Integrate all the above tasks and make the XYZ.com shopping portal functional. How do I develop this application with following proper steps of development ?

  • Where are the network boundaries in the Java Connector Architecture (JCA)?

    - by Laird Nelson
    I am writing a JCA resource adapter. I'm also, as I go, trying to fully understand the connection management portion of the JCA specification. As a thought experiment, pretend that the only client of this adapter will be a Swing Java Application Client located on a different machine. Also assume that the resource adapter will communicate with its "enterprise information system" (EIS) over the network as well. As I understand the JCA specification, the .rar file is deployed to the application server. The application server creates the .rar file's implementation of the ManagedConnectionFactory interface. It then asks it to produce a connection factory, which is the opaque object that is deployed to JNDI for the user to use to obtain a connection to the resource. (In the case of JDBC, the connection factory is a javax.sql.DataSource.) It is a requirement that the connection factory retain a reference to the application-server-supplied ConnectionManager, which, in turn, is required to be Serializable. This makes sense--in order for the connection factory to be stored in JNDI, it must be serializable, and in order for it to keep a reference to the ConnectionManager, the ConnectionManager must also be serializable. So fine, this little object graph gets installed in the application client's JNDI tree. This is where I start to get queasy. Is the ConnectionManager--the piece supplied by the application server that is supposed to handle connection management, sharing, pooling, etc.--wholly present on the client at this point? One of its jobs is to create ManagedConnection instances, and a ManagedConnection is not required to be Serializable, and the user connection handles it vends are also not required to be Serializable. That suggests to me that the whole connection pooling machinery is shipped wholesale to the application client and stuffed into its JNDI tree. Does this all mean that JCA interactions from the client side bypass the server-side componentry of the application server? Where are the network boundaries in the JCA API?

  • About Interview structure for test automation lab developers

    - by Ikaso
    Hi, I am interviewing new applicants for a team that is doing test automation on our company product(s). The team is composed of junior software developers and a team leader. The product runs on windows and has both managed and unmanaged parts. The test automation is done on both client side (user mode and kernel mode) and server side (IIS, Windows Services, backend). We are doing mainly intergration tests and black box tests. I am trying to figure out how to organize my interview. My overall idea is to ask about a project they have done, then ask some technical questions (multithreading, GC, design patterns) and one programming question. Please note that there is another interview done before me with 2 programming questions. My programming question is rather simple (for example: reversing a singly-linked linked list). My coworkers think that my questions will not find good developers since my questions are rather simple and well known, but so far most of the applicants fail those questions. My questions are: Should I change the structure of my interview for this kind of job? What questions do you ask to figure our if the applicant is test oriented? (Maybe I should provide a buggy implementation of a problem and let them find the bugs and then ask them about what tests they would have done) Regards,

  • Is going for a BCS the right move for me?

    - by Michel Carroll
    I'm at a fork in the road. I need somebody to give me some advice from their personal journey in IT. At the moment, I have a college diploma (2 years) in Computer Programmer, and about 2 years of professional experience in the field of software. I'm currently freelancing my programming skills to the public, and am enjoying a nice income, and the rewards of flexibly working on a variety of projects with different cool people. I'm young (21 years old), passionate about software, technology, the internet, and also business. I know if I ever want to dwell deeper into the software industry, I might have a hard time doing so without a Bachelors in Computer Science. On one side, I think I'm better off getting my BCS while I'm still young and malleable. Also, the thought of learning even more stuff in my field is really exciting to me. On the flip side, it means another 3-4 years of studying, and jeopardizing my chances of going on vacation and accumulating wealth for a long time. Considering that I'm already pretty successful with my college diploma, do you think it's a good idea for me to go get my BCS? Will it open up many more doors in the future?

  • Creating C++ client app for some abstract windows server - how to manage TCP connection to server speed?

    - by Kabumbus
    So we have some server with some address port and ip. we are developing that server so we can implement on it what ever we need for help. What are standard/best practices for data transfer speed management between C++ windows client app and server (C++)? My main point is in how to get how much data can be uploaded/downloaded from/to client via his low speed network to my relatively super fast server. (I need it for set up of his live stream Audio/Video bit rate) My try on explaining number 3. We do not care how fast is our server. It is always faster than needed. We care about client tyring to stream out to our server his media. he streams encoded (via ffmpeg) live video data to our server. But he has say ADSL with 500kb/s of outgoing traffic. Also he uses some ICQ or what so ever so he has less than 500 kb/s per second. And he wants to stream live video! So we need to set up our ffmpeg to encode video with respect to the bit rate user can provide. We develop server side and client side. We need a way of finding out how much user can upload per second currently (so value can change dynamically over time)

  • Telerik RadGrid: grid clientside pagination

    - by ram
    I have a web service which returns me some data,I am massaging this data and using this as datasource for my radgrid (telerik). The datasource is quite large, and would like to paginate it. I found couple of problems when I paginate it in the server side I have to bind the grid again for pagination, which essentially means I have to make a call to WS again to get the data. This is an expensive call for me. I would rather forgo the benefits of pagination and would display all the results in the same page, except for it would be a bit clumsy During the postback RadGrid1.Items.Count happens to be the number of items getting paginated (25- in my case) which is expected as all the items in the datasource are not getting bound. This of course is not an issue. The real issue is that we have some checkboxes which get checked based on some business condition. We add this to our business object/DB later. So if the user has not navigated all the pages, these "checked" items do not get added as pagination limits the "Items" in the grid to those which get bound for that particular page index. My Thoughts: I would rather have some sort of client side pagination, where we can hide/show contents than going to the server and doing a databind every time. Though it will return all the results, the UI will not be clumsy and the grid would have "all the items" during postback Is there a way to do it ? If it were a regular asp.net gridView, can someone point me to a good article which would serve my purpose Ram PS: who else think radgrid is crazy ? (unfortunately I did not make this choice)

  • Visual Studio C++ Solution in Maven2

    - by graham.reeds
    A new project is coming up that will require interaction between Java and C++. It's been decided that the project will be built via Maven2. Unfortunately I don't know anything about Maven and the Java guys don't know anything about C++. They have their build chain all set up with various reports being emitted for each part related to CheckStyle, Findbugs, Corbortura(?) etc. and they want the same to be done with the C++ side. Currently we have 4 apps that need building: 2 services, a tray app and a simple dialog based application. I've been told I need to have a pom for each and configure each to output to a target directory, have the tool chain produce the reports - the most particular being the code coverage which the client wants 100%. I have sourced the tools - Bullseye and QA-C++ and requested eval copies - but I am dismayed to find there is very little information on C++ & Maven, and what little there is seems to be horror stories. Does anyone on SO have a good story about it (or have link to blog post)? Is there a simple explanation anywhere for configuring a Visual Studio solution (preferably C++) to be Mavenized? I am expecting pain but I am getting increasingly wary of this venture - but unfortunately the project manager is Java side and seems hell-bent on Mavenizing it.

  • IIS doesn't send two responses to the same client at the same time (only for ASP)

    - by dr. evil
    I've got 2 ASP pages. I do a request to the first page from Firefox (which takes 30 seconds to process on server-side), and during the execution of 30 seconds I do another request from Firefox to the second page (takes less than 1 second in server-side), but it does come after 31 second. Because it waits first requests to finish. When I request to the first page from Firefox and then request the second page from IE it's just instant. So basically ASP - IIS 6 somehow limiting every client to one request (long processing request) at a time. I need to get around this problem in my .NET client application. This is tested in 3 different systems. If you want to test you can try the ASP scripts at the end. This behaviour is same in a long SQL execution or just in a time consuming ASP operation. Note: It's not about HTTP Keep Alive It's not about persistent connection limit (we tried to increase this in firefox and in .NET with Net.ServicePointManager.DefaultConnectionLimit) It's not about User Agent This doesn't happen in ASP.NET so I assume it's something to the with ASP.dll I'm trying to solve this on the client not the server. I don't have direct control over the server it's a 3rd party solution. Is there any way to get around this? Sample ASP Code: First ASP: <% Set cnn = Server.CreateObject("Adodb.Connection") cnn.Open "Provider=sqloledb;Data Source=.;Initial Catalog=master;User Id=sa;Password=;" cnn.Execute("WAITFOR DELAY '0:0:30'") cnn.Close %> Second ASP: <% Response.Write "bla bla" %>

When building the site, I often used hidden form fields to pass data back to the server so that I know which record to update. an example might be: <input type="hidden" name="id" value="132" /> <input type="text" name="total_price" value="15.02" /> When the form is submitted, these values get passed to the server and I update the records based on the data passed (i.e. the price of record 132 would get changed to 15.02). I recently found out that you can change the attributes and values via something as simple as firebug. So...I open firebug and change the id value to "155" and the price value to "0.00" and then submit the form. Viola! I view product number 155 on the site and it now says that it's $0.00. This concerns me. How can I know which record to update without either a query string (easily modified) or a hidden input element passing the id to the server? And if there's no better way (I've seen literally thousands of websites that pass the data this way), then how would I make it so that if a user changes these values, the data on the server side is not executed (or something similar to solve the issue)? I've thought about encrypting the id and then decrypting it on the other side, but that still doesn't protect me from someone changing it and just happening to get something that matches another id in the database. I've also thought about cookies, but I've heard that those can be manipulated as well. Any ideas? This seems like a HUGE security risk to me.

  • Telerik chart not loading correctly in new window (ajax issue?)

    - by Phillip Schmidt
    I have a page which contains user controls with Telerik Charts (grids also, but they work fine). From this page, the user can click on a button to be redirected to a "Printer-Friendly Version" type page, which opens a new window via javascript and goes through a slightly different view (for formatting and stuff), but the telerik code is all the same. The problem is, my Chart displays just fine in the original window, but the new window displays basically an empty chart with no data. This bug is only present in IE, and only applies to Charts. Grids work fine, for whatever reason. I'm thinking this is due to differences in script caching between browsers -- correct me if I'm wrong, I'm semi-new to client-directed web development. Anyway I read somewhere that Telerik has issues with loading data and/or js files when loaded via ajax, so maybe that's the problem? If so, how could I get around this? And if not, any ideas on what could be causing this issue? It's causing me a great deal of frustration, since a print preview page seems like it should be the easiest of jobs. Edit: The charts are being rendered as html (if somebody can explain how to render them as images, that would be awesome). And dev tools shows basically the same thing between chrome and IE. Whenever my web service goes back up ill WinMerge them and look for any peculiarities/differences between them. In the mean time, though, the "render as an image" concept sounds promising. That way I could just save the image from the first page, and insert it right into the print preview page, right?. And since it's a print-preview page, it's not going to need to be interactive or anything, so that'd work out nicely. Another (important) Edit: These are probably the culprit... And here is a little more detail on that: And here is a side-by-side of it working(in chrome) and not working (in IE):

  • Statistical analysis on large data set to be published on the web

    - by dassouki
    I have a non-computer related data logger, that collects data from the field. This data is stored as text files, and I manually lump the files together and organize them. The current format is through a csv file per year per logger. Each file is around 4,000,000 lines x 7 loggers x 5 years = a lot of data. some of the data is organized as bins item_type, item_class, item_dimension_class, and other data is more unique, such as item_weight, item_color, date_collected, and so on ... Currently, I do statistical analysis on the data using a python/numpy/matplotlib program I wrote. It works fine, but the problem is, I'm the only one who can use it, since it and the data live on my computer. I'd like to publish the data on the web using a postgres db; however, I need to find or implement a statistical tool that'll take a large postgres table, and return statistical results within an adequate time frame. I'm not familiar with python for the web; however, I'm proficient with PHP on the web side, and python on the offline side. users should be allowed to create their own histograms, data analysis. For example, a user can search for all items that are blue shipped between week x and week y, while another user can search for sort the weight distribution of all items by hour for all year long. I was thinking of creating and indexing my own statistical tools, or automate the process somehow to emulate most queries. This seemed inefficient. I'm looking forward to hearing your ideas Thanks

  • How to handle duplicate values in d3.js

    - by Mario
    First I'm a d3.js noob :) How you can see from the title I've got a problem with duplicated data and aggregate the values is no option, because the name represent different bus stops. In this example maybe the stops are on the fron side and the back side of a building. And of course I like to show the names on the x-axis. If i created an example and the result is a bloody mess, see jsFiddel. x = index name = bus stop name n = value I've got a json e.g.: [{ "x": 0, "name": "Corniche St / Abu Dhabi Police GHQ", "n": 113 }, { "x": 1, "name": "Corniche St / Nation Towers", "n": 116 }, { "x": 2, "name": "Zayed 1st St / Al Khalidiya Public Garden", "n": 146 }, ... { "x": 49, "name": "Hamdan St / Tariq Bin Zeyad Mosque", "n": 55 }] The problem: It is possible that the name could appear more then once e.g. { "x": 1, "name": "Corniche St / Nation Towers", "n": 116 } and { "x": 4, "name": "Corniche St / Nation Towers", "n": 105 } I like to know is there a way to tell d3.js not to use distinct names and instead just show all names in sequence with their values. Any ideas or suggestions are very welcome :) If you need more information let me know. Thanks in advanced Mario
