  • Is there anyway of making json data readable by a Google spider?

    - by leeand00
    Is it possible to make JSON data readable by a Google spider? Say for instance that I have a JSON feed that contains the data for an e-commerce site. This JSON data is used to populate a human-readable page in the users browser. (I.E. The translation from JSON data to human displayed page is done inside the users browser; not my choice, just what I've been given to work with, its an old legacy CGI application and not an actual server-side scripting language.) My concern here is that, the google spiders will not be able to pickup/directly link to the item in question when a user clicks on it in google, being presented with an index page full of all the items, rather than being linked directly to the item they clicked on. Is there anyway of "informing" the google spider in the JSON that what they should feed the user a different link?

  • Python OOP and lists

    - by Mikk
    Hi, I'm new to Python and it's OOP stuff and can't get it to work. Here's my code: class Tree: root = None; data = []; def __init__(self, equation): self.root = equation; def appendLeft(self, data): self.data.insert(0, data); def appendRight(self, data): self.data.append(data); def calculateLeft(self): result = []; for item in (self.getLeft()): if (type(item) == type(self)): data = item.calculateLeft(); else: data = item; result.append(item); return result; def getLeft(self): return self.data; def getRight(self): data = self.data; data.reverse(); return data; tree2 = Tree("*"); tree2.appendRight(44); tree2.appendLeft(20); tree = Tree("+"); tree.appendRight(4); tree.appendLeft(10); tree.appendLeft(tree2); print(tree.calculateLeft()); It looks like tree2 and tree are sharing list "data"? At the moment I'd like it to output something like [[20,44], 10, 4], but when I tree.appendLeft(tree2) I get RuntimeError: maximum recursion depth exceeded, and when i even won't appendLeft(tree2) it outputs [10, 20, 44, 4] (!!!). What am I missing here? I'm using Portable Python 3.0.1. Thank you

  • How do I insert data from a Python dictionary to MySQL?

    - by NJTechie
    I manipulated some data from MySQL and the resulting dictionary "data" (print data) displays something like this : {'1': ['1', 'K', abc, 'xyz', None, None, datetime.date(2009, 6, 18)], '2': ['2', 'K', efg, 'xyz', None, None, None, None], '3': ['3', 'K', ijk, 'xyz', None, None, None, datetime.date(2010, 2, 5, 16, 31, 2)]} How do I create a table and insert these values in a MySQL table? In other words, how do I dump them to MySQL or CSV? Not sure how to deal with datetime.date and None values. Any help is appreciated.

  • Using jquery to make a POST, how to properly supply 'data' parameter?

    - by user246114
    Hi, I'd like to make an ajax call as a POST, it's going to go to my servlet. I want to send parameterized data, like the following: var mydata = 'param0=some_text&param1=some_more_text'; I supply this as the 'data' parameter of my jquery ajax() call. So this should be inserted in the body of the POST, right? (I mean, not appended to my 'mysite/save' url?): $.ajax({ url: 'mysite/save', type: 'POST', data: mydata }); it appears to work correctly. In my servlet, I am just dumping all received parameters, and I see them all come through nicely: private void printParams(HttpServletRequest req) { Enumeration paramNames = req.getParameterNames(); while (paramNames.hasMoreElements()) { // print each param key/val here. } } also, I should url encode my data string manually before use, right? Like: var mydata = 'param0=' + urlencode('hi there!'); mydata += '&param1=' + urlencode('blah blah'); mydata += '%param2=' + urlencode('we get it'); Thanks!

  • In MVC2, how do I validate fields that aren't in my data model?

    - by Andy Evans
    I am playing with MVC2 in VS 2010 and am really getting to like it. In a sandbox application that I've started from scratch, my database is represented in an ADO.NET entity data model and have done much of the validation for fields in my data model using Scott Guthrie's "buddy class" approach which has worked very well. However, in a user registration form that I have designed and am experimenting with, I'd like to add a 'confirm email address' or a 'confirm password' field. Since these fields obviously wouldn't exist in my data model, how would I validate these fields client side and server side? I would like to implement something like 'Html.ValidationMessageFor', but these fields don't exist in the data model. Any help would be greatly appreciated.

  • Cascading S3 Sink Tap not being deleted with SinkMode.REPLACE

    - by Eric Charles
    We are running Cascading with a Sink Tap being configured to store in Amazon S3 and were facing some FileAlreadyExistsException (see [1]). This was only from time to time (1 time on around 100) and was not reproducable. Digging into the Cascading codem, we discovered the Hfs.deleteResource() is called (among others) by the BaseFlow.deleteSinksIfNotUpdate(). Btw, we were quite intrigued with the silent NPE (with comment "hack to get around npe thrown when fs reaches root directory"). From there, we extended the Hfs tap with our own Tap to add more action in the deleteResource() method (see [2]) with a retry mechanism calling directly the getFileSystem(conf).delete. The retry mechanism seemed to bring improvement, but we are still sometimes facing failures (see example in [3]): it sounds like HDFS returns isDeleted=true, but asking directly after if the folder exists, we receive exists=true, which should not happen. Logs also shows randomly isDeleted true or false when the flow succeeds, which sounds like the returned value is irrelevant or not to be trusted. Can anybody bring his own S3 experience with such a behavior: "folder should be deleted, but it is not"? We suspect a S3 issue, but could it also be in Cascading or HDFS? We run on Hadoop Cloudera-cdh3u5 and Cascading 2.0.1-wip-dev.

  • PHP Uploadprogress extension function always returning null, with no upload data.

    - by abhinavlal
    I am using php 5.3.2 with uploadprogress extension to get a progressbar during upload using zend framework. Even the demo provided with zend is not working. code in zend example - if (isset($_GET['uploadId'])) { set_include_path(realpath(dirname(__FILE__) . '/../../../library') . PATH_SEPARATOR . get_include_path()); require_once 'Zend/ProgressBar.php'; require_once 'Zend/ProgressBar/Adapter/JsPull.php'; require_once 'Zend/Session/Namespace.php'; $data = uploadprogress_get_info($_GET['uploadId']); $bytesTotal = ($data === null ? 0 : $data['bytes_total']); $bytesUploaded = ($data === null ? 0 : $data['bytes_uploaded']); $adapter = new Zend_ProgressBar_Adapter_JsPull(); $progressBar = new Zend_ProgressBar($adapter, 0, $bytesTotal, 'uploadProgress'); if ($bytesTotal === $bytesUploaded) { $progressBar->finish(); } else { $progressBar->update($bytesUploaded); } } uploadprogress_get_info always returns null. I thought something is wrong with my code so i downloaded the working sample available at http://labs.liip.ch/uploadprogresssimple/index.php but even in that case in uploadprogress_get_info always return null. My uploadprogress config values uploadprogress support enabled Version 1.0.1 uploadprogress.file.contents_template /tmp/upload_contents_%s uploadprogress.file.filename_template /tmp/upt_%s.txt uploadprogress.get_contents 1 While googling around i found uploadprogress extension has some issue with Suhosin Patch < 0.9.26 but i am using Suhosin Patch 0.9.9.1

  • Is it good to use .settings for storing controls text data?

    - by Zenya
    In my WinForms applications I often put the controls text data (form title, labels texts, button captions, etc.) into a .settings (feature automatically generated by Visual Studio - based on the ApplicationSettingsBase class). In particular, Add a form or a control. In Solution Explorer add a new string item into the application scope of the settings file. Bind the control text property with the corresponding item of the settings file (through the property binding). Good point of this is that all my text data is collected in one place and easy to check and edit. Also it is convenient when I want to use the same text for several controls. However, I haven't heard that somebody uses the .settings such way. In tutorials for creating multilingual applications, for example, it is recommended to enter texts directly into the control property. So, is it good practice to use .settings for storing controls text data? Brief conclusion from the answers: Storing controls text data in the .settings is not common practice.

  • How can you toggle between two sets of values per data series in flot?

    - by Jedidja
    flot has built-in support for multiple data series (sample code) and also dual-axis (sample code). Assuming multiple data series (water, electricity, etc) that each have an amount (usage) and a dollar value (charge for that usage), what would the best way be to to use flot to display either the amount or dollar values for all the data series, while still supporting toggling display for each individual series? The idea is to send down all the data in one GET request and then let the client take care of everything else in Javascript. Ideally we could use triplets somehow {date, amount, charge}, and then possibly split that into two arrays for flot.

  • mysql - how do I load data from a different configuration...

    - by Ronedog
    I'm not sure if this will make sense, but I'll give it a shot. My hard drive went down and I had to reinstall the os along with all my webserver configuration,etc. I kept a backup of the mysql database, but it doesn't contain all the tables...I added a couple tables after my last backup. I have access to the hard drive and the directory where the mysql data files are stored from the failed hard drive, but I don't know how to retrieve the data into my new mysql database. Is it even possible to get the raw data files from mysql and load them into a different instance? I'd even be happy if there was some way for phpmyadmin to show the data files, then I could dump out to a backup txt file, and reload them into my new configuration. Any help will be appreciated. thanks.

  • How can I access data that's stored in my App Delegate from my various view controllers?

    - by BeachRunnerJoe
    This question is similar to this other post, but I'm new to iPhone development and I'm getting used to the good practices for organizing my data throughout my app. I understand the ApplicationDelegate object to be the best place to manage data that is global to my app, correct? If so, how can I access data that's stored in my App Delegate from various view controllers? Specifically, I have an array of table section titles for my root table view controller created as such... appdelegate.m sectionTitles = [[NSArray alloc] initWithObjects: @"Title1", @"Title2", @"Title3", nil]; rootViewController.appDelegate = self; and I need to access it throughout the different views of my app, like such... rootviewcontroller.m NSUInteger numSections = [self.appDelegate.sectionTitles count]; Is this the best way to do it or are there any reasons I should organize my data a better way? Thanks so much in advance for your help!

  • What can be the reason for Windows error ERROR_DISK_FULL (112) when opening a NTFS alternate data st

    - by ur
    My application writes some bytes of data to an alternate data stream. This works fine on all but one machine (Windows Server 2003 SP2). Instead, CreateFile returns ERROR_DISK_FULL when I try to create an alternate data stream (on the root directory). I don't find the reason for this result, because... There's plenty of space on that drive. The drive is NTFS formatted (due to GetVolumeInformation). The drive supports altenate data streams (due to GetVolumeInformation). Edit: I can provide some more information about what the reason not is: I added many streams on a test system which didn't show the error and wondered if the error might occur. It didn't. Instead after about 2000 Streams with long file names another error occurred and persisted: 1450 (ERROR_NO_SYSTEM_RESOURCES). EDIT: Here is an example for one of the used file names: char szStreamFileName[] = "C:\\:abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnoqrstuvwxyz012345"; EDIT: Our customer uses some corporate antivirus software from Avira on this server. Maybe this is the reason (Alternate data streams can be abused by malware).

  • Should I use DTOs as my data models in MVVM?

    - by JonC
    I'm currently working on what will be my first real foray into using MVVM and have been reading various articles on how best to implement it. My current thoughts are to use my data models effectively as data transfer objects, make them serializable and have them exist on both the client and server sides. It seems like a logical step given that both object types are really just collections of property getters and setters and another layer in between seems like complete overkill. Obviously there would be issues with INotifyPropertyChanged not working correctly on the server side as there is no ViewModel to which to communicate, but as long as we are careful about constructing our proper domain model objects from data models in the service layer and not dealing the the data models on the server side I don't think it should be a big issue. I haven't found too much info about this approach in my reading, so I would like to know if this is a pretty standard thing, is this just assumed to be the de facto way of doing MVVM in a multi-tier environment? If I've got completely the wrong idea about things then thoughts on other approaches would be appreciated too.

  • php : is this if condition correct?

    I have the following if condition statement if ( (strlen($data[70])>0) || ( (remove19((trim($data[29])) == '7135556666')) && isLongDistance($data[8])) ) where $data is a recordset from a database. My goal is to include all rows where $data[70] isn't blank, and also include rows where $data[29] = 713555666 && $data[8] isLongDistance = TRUE My question is, if isLongDistance($data[8]) returns false, will it still return the row since $data[70] is not blank? thanks in advance

  • How can you tell the source of the data when using the Stream.BeginRead Method?

    - by xarzu
    When using the Stream.BeginRead Method, and you are reading from a stream into a memory, how is it determined where you are reading the data from? See: http://msdn.microsoft.com/en-us/library/system.io.stream.beginread.aspx In the list of parameters, I do not see one that tells where the data is being read from: Parameters buffer Type: System.Byte[] The buffer to read the data into. offset Type: System.Int32 The byte offset in buffer at which to begin writing data read from the stream. count Type: System.Int32 The maximum number of bytes to read. callback Type: System.AsyncCallback An optional asynchronous callback, to be called when the read is complete. state Type: System.Object A user-provided object that distinguishes this particular asynchronous read request from other requests.

  • How to manage data access / preloading efficiently using web services in C# ?

    - by Amadeus45
    Hello all, Ok, this is very "generic" question. We currently have a SQL Server database for which we need to develop an application in ASP.NET with will contain all the business logic in C# Web Services. The thing is that, architecturally speaking, I'm not sure how to design the web service and the data management. There are many things to consider : We need have very rapid access to data. Right now, we have over a million "sales" and "purchases" record from which we need to often calculate and load the current stock for a given day according to a serie of parameter. I'm not sure how we should preload the data and keep the data in the Web Service. Doing a stock calculation within a SQL query will be very lengthy. They currently have a stock calculation application that preloads all sales and purchases for the day and afterwards calculate the stock on the code-side. We want to develop powerful reporting tools. We want to implement a "pivot table" but not sure how to implement it and have good performances. For the reasons above, I'm not sure how to design the data model. Anybody can give me any guidelines on how to start, or from their personnal experiences (what have you done in the past ?) I'm not sure if it's possible to make a bounty even though the question is new (I'd put 300 rep on it, since I really need something). If you know how, let me know. Thanks
