  • Scraping with multiple IP, in java.

    - by Titi Wangsa bin Damhore
    Well basically I have a scraping application. It scrapes around n items per minute. currently i have only one IP. The site i'm scraping allows me 3 connections per IP. I'm thinking about getting another IP. so i'll be able to get 6 connections. in theory i should be able to get n items in 40 seconds, more or less. currently i'm using java (commons-httpcore) to get the job done. I'm not sure if this is java question or an OS question. my machine has IP 1 and IP 2 how do i connect to, say, www.microsoft.com, using IP 1 and using IP2? how can i specify, which ip i want to use to do a connection?

  • Java SWT - dissolve (fade) from one image to the next.

    - by carillonator
    I'm pretty new to Java and SWT, hoping to have one image dissolve into the next. I have one image now in a Label (relevant code): Device dev = shell.getDisplay(); try { Image photo = new Image(dev, "photo.jpg"); } catch(Exception e) { } Label label = new Label(shell, SWT.IMAGE_JPEG); label.setImage(photo); Now I'd like photo to fade into a different image at a speed that I specify. Is this possible as set up here, or do I need to delve more into the org.eclipse.swt.graphics api? Also, this will be a slide show that may contain hundreds of photos, only ever moving forward (never back to a previous image)---considering this, is there something I explicitly need to do in order to remove the old images from memory? Thanks!!

  • fields_for to stop pluralizing.

    - by Dmitriy Likhten
    I have a fields_for tag, where I specify the prefix (lets say for some good reasons), and this is supposed to represent a one-to-one relationship. I am trying to represent a relationship widget has_many thingamagigs thingamagig has_one whatchamacallit The field_for code is: fields_for "widgt[thingamagigs_attributes][][whatchamacallit_attributes]", thingamagig.whatchamacallit do |x| which generates names (wrongly): widget[thingamagigs_attributes][][whatchamacallit_attributes][][value] The better solution would be t.fields_for :whatchamacallit do |x| where t = fields_for the thingamagig... However if I do that, the following names are generated widgt[thingamagigs_attributes][whatchamacallit_attributes][] which is completely wrong as all other fields for a thingamagig is... widgt[thingamagigs_attributes][][name] So in all cases I am screwed. The original field_for using a string cannot be used with accepts_nested_attributes_for :whatchamacallit since whatchamacallit is a singular relationship and an object is expected not an array. The second fields_for will simply not work because rails cannot parse the params object correctly. Is there a way to tell the first forms_for to not add the [] after [whatchamacallit_attributes] in all field names?

  • Multiple WCF Services implementing same Service Contract interface

    - by andrewczwu
    Is it possible for multiple wcf services to implement the same service contract interface? What I want to do is allow for a test service to be interchangeable for the real service, and to specify which service to be used in the configuration file. For example: [ServiceContract] public interface IUselessService { [OperationContract] string GetData(int value); } Test implementation public class TestService : IUselessService { public string GetData(int value) { return "This is a test"; } } Real class public class RealService : IUselessService { public string GetData(int value) { return string.Format("You entered: {0}", value); } }

  • RFC822 Timezone Parsing in Java

    - by Jamen
    Hi, I have a JS date that is being converted by Dojo into RFC822 format. The function call - dojo.date.toRfc3339(jsDate), generates the following date - 2007-02-26T20:15:00+02:00. I have an application that uses a Java date SimpleDateFormat to parse in the dates generated above. I am having problems parsing this date format due to the timezone. I have attempted to use yyyy-mm-DD'T'hh:mm:ssZ This fails as the 'Z' for timezone doesn't expect a ':' character. Does anyone know how I would specify a pattern to handle a RFC822 date with the ':'? Thanks Jamen

  • inputMismatchException Java reading doubles from plain text file

    - by user939287
    Using double variable = inputFile.nextDouble(); Gives the mismatch error and I can't figure out why... Anyone know what's up? The input file is just a bunch of doubles like 5.0... Okay here is the code snippet String fileName; Scanner scanner = new Scanner(System.in); System.out.println("\nEnter file name that contains the matrix and vector: "); fileName = scanner.nextLine(); Scanner inputFile = new Scanner(fileName); double a1 = inputFile.nextDouble(); the input file is a plain text document .txt in this format 5.0 4.0 -3.0 4.0 2.0 5.0 6.0 5.0 -2.0 -13.0 4.0 12.0 I don't understand why it wouldn't take those as doubles... As far as what its expecting the format of the file to be... I suppose binary? isn't that the default? I didn't specify in the code...

  • c# project cannot find c++ .dll?

    - by flavour404
    I have a working c++ dll that works in one c# project that I am calling via the interop service. I have created another c# project and am trying to call the same .dll but keep getting a generic error message stating that the .dll cannot be found, both project are .net 2.0. What folder, and where do I specify in the project, should I put the .dll file in so that the project can find it? Think of it as a reminder for me... In the previous project I did not have a reference to it, I just had it in the /bin folder and doing the same thing for this project does not work. Thanks R.

  • using different string files in android

    - by boreas
    I'm porting my iPhone app to android and I'm having a problem with the string files now. The app is a translation tool and users can switch the languages, so all the localized strings are in both languages and they are independent from what locale the OS is running. For iOS version I have different files like de.strings, en.strings and fr.strings and so on. For every target with specified language pair I read the strings from the string tables, e.g. for de-fr I will include de.strings and fr.strings in project and set the name of the string tables in the info-list file and read strings from them. In the end I have one project containing different targets (with different info-list files) and all are well configured. I'm intending to do the same on android platform, but Is only one strings.xml allowed per project? How do I set different build target? How do I specify per target which strings.xml it should read?

  • Setting the size of a silverlight window at runtime automatically?

    - by dilbert789
    I need to be able to change the size of my Silverlight object at run time because I have content that changes in size dramatically between pages, and I'd rather not show a Silverlight scroll bar inside the browser scroll bar. I was able to do the following to get it to work: In the aspx page hosting the silverlight control: - Set your Div to the starting size you need it to be - Set the Silverlight Obejct to width=”100%” height=”100%” In your Main page add this: public static void ChangeSize(string height) { var myDiv = HtmlPage.Plugin.Parent; while (myDiv.TagName != "div") myDiv = myDiv.Parent; myDiv.SetStyleAttribute("height", height); } Anywhere you want to now change the size of the page do this: string newHeight = (App.Current.Host.Content.ActualHeight + 75).ToString(); MainPage.ChangeSize(newHeight + "px"); //App.Current.Host.Content.ActualHeight will get the current actual height of the object Is there a way that I can set this to re-size automatically so that I do not have to specify the amount to change? Currently using SL 2, interested in if there is another way in a different version though.

  • Loading multiple embedded flash apps onto an HTML page- problem with ordering

    - by shudson250
    We need to load an embedded version of a site written in Flash, and not originally designed to load multiple instances of itself, on a HTML page. The specific issue is how to get them to load in order when embedded, given that they are all being opened by the same instance of the flash player. It's a complicated mapping application, and at the moment, the maps and data get intermixed as the session variables are overwritten by another instance starting to load before the previous one has finished. We need a way to have them load sequentially, one finishing before another starts to load. The most we can specify in the URL is an &order=1 or similar. We have PHP and SQL on the backend. Edit: The embedded versions are being loaded in an iFrame of a parent site. One php file loads one swf, as many times as the parent site desires.

  • VS JavaScript intellisense with paramaters

    - by TonyB
    here is some sample javascript: SomeObjectType = function() { } SomeObjectType.prototype = { field1: null, field2: null } SomeOtherObject = function() { } SomeOtherObject.prototype = { doSomething: function(val) { /// <param name="val" type="SomeObjectType"></param> var val2 = new SomeObjectType(); //val2. shows intellisense correctly //val1. does NOT } } Shouldn't visual studio be giving me intellisence when i do "val." inside the "doSomething" function? I would expect it to give me field1 and field2 as options, but it doesn't. I DO get field1 and field2 if I type "val2." so intellisence works when I create a new object of the same type that I specify in the param comment. Any ideas what I am doing wrong or is this just not supported?

  • PHP --> SQL Server + Excel file upload from a specific row

    - by lucky
    I have a requirement in which, i need to upload an excel file into SQL Server database. It is working well till this point. But sometimes i am getting excel file in such a way, that the first 2 rows and columns are empty rows. That is not even fixed every time. so the format of the table after upload is not as expected. It is assigning F1, F2 as column names for the table in SQL Server. It varies from file to file. I want to program it in such away so that the user can enter the row number and the column number from where the actual data is starting. So that while upload it should from line 3 and column 2. I don't know how to specify that row and column while uploading. Please help me to solve the same.

  • defaults for to_json in Rails with :include

    - by prateekdayal
    Let us say I have a model Post which belongs to a User. To convert to json, I do something like this @reply.to_json(:include => {:user => {:only => [:email, :id]}, :only => [:title, :id]) However, I want to set some defaults for this so I don't have to specify :only everytime. I am trying to override as_json to accomplish this. When I add as_json in User model, it is called when I do @user.to_json but when user is included in @reply.to_json, my overriden as_json for User is ignored. How do I make this work? Thanks

  • Does specifying image size in CSS allow the browser to do layout before download is complete?

    - by eaolson
    I've always tried to specify the height and width attributes for img tags in HTML. Not for style reasons, but because the browser then expects the size of the image and can do page layout even before the image has finished downloading. From the HTML spec: The height and width attributes give user agents an idea of the size of an image or object so that they may reserve space for it and continue rendering the document while waiting for the image data. I don't know why this has never occurred to me, but does specifying height and width in CSS, rather than inside the img tag, do the same thing?

  • How to find text in images with the browser control+F

    - by Riga
    Have HTML pages with many sections and each section has a section title displayed as an image (to use nice font). The problem is that even if I specify an 'alt' and 'title' text on each image/title the Ctrl+F browser functionality does not find the text. Thought two possible solutions but not very happy about them 1) Use embed fonts. Problem: Can not find the font required by client to use and not sure about copyrights. 2) Have the text in the image in DIV near the image but hidden from user view. Problem: Can search engines consider this keyword stuffing? Will browser find text if display:none Does anybody has a better solution? Thanks Riga

  • Persisting Serializable Objects in Hibernate

    - by VeeArr
    I am attempting to persist objects that contain some large Serializable types. I want Hibernate to automatically generate my DDL (using Hibernate annotations). For the most part, this works, but the default database column type used by Hibernate when persisting these types is tinyblob. Unfortunately, this causes crashes when attempting to persist my class, because these types will not fit within the length of tinyblob. However, if I manually set the type (using @Column(columnDefinition="longblob")), it works fine. Is there any way to make the default binary type longblob instead of tinyblob, so that I don't need to manually specify the @Column annotation on each field?

  • ArrayIndexOutOfBound exception even though I check for array length!

    - by xtracto
    I have the following code in some app: int lowRange=50; int[] ageRangeIndividual = {6, 10, 18, 25, 45, 65, 90}; int index=0; for (; index<ageRangeIndividual.length-1 && ageRangeIndividual[index]<=lowRange;index++); I am getting an "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 7" in the for line! even though I explicitly specify to break the cycle if index < last indexable item in the array! This does not happen always, but after some time of running said program (lowRange varies each time the function is called) What am I not seeing?

  • aov define F values computation

    - by essopapas
    Greetings to all This is my model: aov.fit<-aov(Y~A+B+C+D+E+A:C+A:E, data=dat) In summary(aov.fit) all F values are comptuted by eg MS(A)/MS(Residuals). This is not correct (or what I want), except for F(B) and F(A:E). I suppose P values are not correct either. Can I specify how the F computations will be done? I 'd like them to be like this: F(A)=MS(A)/MS(E), F(C)=MS(C)/MS(E), F(D)=MS(D)/MS(E), F(E)=MS(E)/MS(A:E), F(A:C)=MS(A:C)/MS(A:E) thanks

  • Creating a file path in C#

    - by Jason
    So I'm trying to create a path in C#. I use Environment.Machinename and store it a variable serverName. Then I create another string variable and have some other path extension in there. Here is my code so far: string serverName = Environment.MachineName; string folderName = "\\AlarmLogger"; No matter what I do I can't seem to obtain only one backslash prior to AlarmLogger. Any ideas how I can specify a path in C#? Edit: I'm wondering if my code doesn't seem to want to paste correctly. Anyways when i paste it I only see one backslash but my code has two. Because of the escape character sequence. But something like string test = @"\" + serverName + folderName doesn't seem to want to work for me.

  • Serialization of a TChan String

    - by J Fritsch
    I have declared the following type KEY = (IPv4, Integer) type TPSQ = TVar (PSQ.PSQ KEY POSIXTime) type TMap = TVar (Map.Map KEY [String]) data Qcfg = Qcfg { qthresh :: Int, tdelay :: Rational, cwpsq :: TPSQ, cwmap :: TMap, cw chan :: TChan String } deriving (Show) and would like this to be serializable in a sense that Qcfg can either be written to disk or be sent over the network. When I compile this I get the error No instances for (Show TMap, Show TPSQ, Show (TChan String)) arising from the 'deriving' clause of a data type declaration Possible fix: add instance declarations for (Show TMap, Show TPSQ, Show (TChan String)) or use a standalone 'deriving instance' declaration, so you can specify the instance context yourself When deriving the instance for (Show Qcfg) I am now not quite sure whether there is a chance at all to serialize my TChan although all individual nodes in it are members of the show class. For TMap and TPSQ I wonder whether there are ways to show the values in the TVar directly (because it does not get changed, so there should no need to lock it) without having to declare an instance that does a readTVar ?

  • Matplotlib Contour Clabel Location

    - by jotimaz
    I would like to control the location of matplotlib clabels on a contour plot, but without utilizing the manual=True flag in clabel. For example, I would like to specify an x-coordinate, and have labels created at the points that pass through this line. I see that you can get the location of the individual labels using get_position(), but I am stuck at that. Any help would be greatly appreciated. Thanks! EDIT: The above image is an example plot that I would like to apply this method to. The default label positions are inconvenient -- the flat areas between Day 2 and Day 4 would be more visually appealing.

  • Wordpress php: Way to test if pages are children of a parent page?

    - by Erykan
    Hi - Working on my first Wordpress site so I'm sure this is a really basic question. I'm struggling to write a conditional php statement that performs a certain action when a page is a child of a parent page. For example, rather than just specifying one page, as below, I'd like to specify all pages that have the 'About Us' page as a parent: <?php if (is_page('About Us')) echo 'Hello World!'; ?> I've tried the "child_of" function but it wasn't as straightforward as I'd hoped. When I use the below, I get a syntax error - probably just me not knowing how to use the function: <?php if (child_of('About Us')) echo 'Hello World!'; ?> Any suggestions? Thanks!!

  • Annotation retention policy: what real benefit is there in declaring `SOURCE` or `CLASS`?

    - by watery
    I know there are three retention policies for Java annotations: CLASS: Annotations are to be recorded in the class file by the compiler but need not be retained by the VM at run time. RUNTIME: Annotations are to be recorded in the class file by the compiler and retained by the VM at run time, so they may be read reflectively. SOURCE: Annotations are to be discarded by the compiler. And although I understand their usage scenarios, I don't get why it is such an important thing to specify the retention policy that retention policies exist at all. I mean, why aren't all the annotations just kept at runtime? Do they generate so much bytecode / occupy so much memory that stripping those undeclared as RUNTIME does make that much difference?
