  • validating an XML schema with empty attributes

    - by AdRock
    I am having trouble validating my xml schema. I get these errors on the schema 113: 18 s4s-elt-invalid-content.1: The content of '#AnonType_user' is invalid. 164: 17 s4s-elt-invalid-content.1: The content of '#AnonType_festival' is invalid. Element 'sequence' is invalid, misplaced, or occurs too often. and becuase of those 2 errors, i am getting loads of the same error. This is becuase the attribute id of the festival tag may be empty becuase there is not data for that festival cvc-datatype-valid.1.2.1: '' is not a valid value for 'integer'. cvc-attribute.3: The value '' of attribute 'id' on element 'festival' is not valid with respect to its type, 'integer'.

  • Finding the lowest average Hamming distance when the order of the strings matter

    - by user1049697
    I have a sequence of binary strings that I want to find a match for among a set of longer sequences of binary strings. A match means that the compared sequence gives the lowest average Hamming distance when all elements in the shorter sequence have been matched against a sequence in one of the longer sets. Let me try to explain with an example. I have a set of video frames that have been hashed using a perceptual hashing algorithm so that the video frames that look the same has roughly the same hash. I want to match a short video clip against a set of longer videos, to see if the clip is contained in one of these. This means that I need to find out where the sequence of the hashed frames in the short video has the lowest average Hamming distance when compared with the long videos. The short video is the sub strings Sub1, Sub2 and Sub3, and I want to match them against the hashes of the long videos in Src. The clue here is that the strings need to match in the specific order that they are given in, e.g. that Sub1 always has to match the element before Sub2, and Sub2 always has to match the element before Sub3. In this example it would map thusly: Sub1-Src3, Sub2-Src4 and Sub3-Src5. So the question is this: is there an algorithm for finding the lowest average Hamming distance when the order of the elements compared matter? The naïve approach to compare the substring sequence to every source string won't cut it of course, so I need something that preferably can match a (much) shorter sub string to a set of million of elements. I have looked at MVP-trees, BK-trees and similar, but everything seems to only take into account one binary string and not a sequence of them. Sub1: 100111011111011101 Sub2: 110111000010010100 Sub3: 111111010110101101 Src1: 001011010001010110 Src2: 010111101000111001 Src3: 101111001110011101 Src4: 010111100011010101 Src5: 001111010110111101 Src6: 101011111111010101 I have added a calculation of the examples below. (The Hamming distances aren't correct, but it doesn't matter) **Run 1.** dist(Sub1, Src1) = 8 dist(Sub2, Src2) = 10 dist(Sub3, Src3) = 12 average = 10 **Run 2.** dist(Sub1, Src2) = 10 dist(Sub2, Src3) = 12 dist(Sub3, Src4) = 10 average = 11 **Run 3.** dist(Sub1, Src3) = 7 dist(Sub2, Src4) = 6 dist(Sub3, Src5) = 10 average = 8 **Run 4.** dist(Sub1, Src3) = 10 dist(Sub2, Src4) = 4 dist(Sub3, Src5) = 2 average = 5 So the winner here is sequence 4 with an average distance of 5.

  • How to set up an insert to a grails created file with next sequence number?

    - by Jack BeNimble
    I'm using a JMS queue to read from and insert data into a postgres table created by grails. The problem is obtaining the next sequence value. I thought I had found the solution with the following statement (by putting "DEFAULT" where the ID should go), but it's no longer working. I must have changed something, because I needed to recreate the table. What's the best way to get around this problem? ps = c.prepareStatement("INSERT INTO xml_test (id, version, xml_text) VALUES (DEFAULT, 0, ?)"); UPDATE: In response to the suggested solution, I did the following: Added this to the the domain: class XmlTest { String xmlText static constraints = { id generator:'sequence', params:[name:'xmltest_sequence'] } } And changed the insert statement to the following: ps = c.prepareStatement("INSERT INTO xml_test (id, version, xml_text) VALUES (nextval('xmltest_sequence'), 0, ?)"); However, when I run the statement, I get the following error: [java] 1 org.postgresql.util.PSQLException: ERROR: relation "xmltest_sequence" does not exist Any thoughts?

  • What is the use of Method Overloading in Java when it is achieved by changing the sequence of parameters in the argument list?

    - by MediumOne
    I was reading a Java training manual and it said that Method Overloading in Java can be achieved by having a different argument list. It also said that the argument list could differ in (i). Number of parameters (ii). Datatype of parameters (iii). Sequence of parameters My concern is about (iii). What is the use of trying to overload a method just by changing the sequence of parameters? I am unable to think of any benefits by this way.

  • Is a server an infinite loop running as a background process?

    - by Tony
    Is a server essentially a background process running an infinite loop listening on a port? For example: while(1){ command = read(127.0.0.1:xxxx); if(command){ execute(command); } } When I say server, I obviously am not referring to a physical server (computer). I am referring to a MySQL server, or Apache, etc. Full disclosure - I haven't had time to poke through any source code. Actual code examples would be great!

  • Grouping parent node based on child elements values and sequence number.

    - by Mahir
    Hi, I need to transform XML using xslt. Logic: Split the parent if the parent having different child address and append the sequence number with parent name. Also need line number for the child. Here we may have number of parent nodes and each parent node may have more number of child nodes. I have tried numerous ways to achieve this and I am stuck with generating sequence number in the foreach. So can any one try and give a solution for this. Source XML as below: P1 CName1 Address1 CName2 Address2 CName3 Address1 P2 CName1 Address1 The target XML should as below: P1_1 CName1 Address1 1 CName2 Address2 2 CName3 Address1 P1_2 1 CName2 Address2 P2_1 1 CName1 Address1

  • Can I control Caption sequence numbering from styles other than "Heading "?

    - by Carl Witthoft
    Similar question to Wrong caption using 'Appendix' header style , so the answer may well be "I can't." I created a style called "Appendix" which is based on "Heading 1" , is at "level 1" , and is numbered A,B,C... . I use the standard "Insert Caption" to get Figure or Table captions. I then modded the first field code to be STYLEREF "Appendix" \s and that properly displays the Appendix letter sequence. However, the second field code, SEQ \s 1 refers to the last "Heading 1" . I've tried things like SEQ \s "Appendix" to no avail. Is there any way around this? Should I generate a new "Appendix caption"-ish style which is a "numbered list" and manually set the 'restart at 1' counting in each Appendix?

  • using xml type attribute for derived complex types

    - by David Michel
    Hi All, I'm trying to get derived complex types from a base type in an xsd schema. it works well when I do this (inspired by this): xml file: <person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Employee"> <name>John</name> <height>59</height> <jobDescription>manager</jobDescription> </person> xsd file: <xs:element name="person" type="Person"/> <xs:complexType name="Person" abstract="true"> <xs:sequence> <xs:element name= "name" type="xs:string"/> <xs:element name= "height" type="xs:double" /> </xs:sequence> </xs:complexType> <xs:complexType name="Employee"> <xs:complexContent> <xs:extension base="Person"> <xs:sequence> <xs:element name="jobDescription" type="xs:string" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> However, if I want to have the person element inside, for example, a sequence of another complex type, it doesn't work anymore: xml: <staffRecord> <company>mycompany</company> <dpt>sales</dpt> <person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Employee"> <name>John</name> <height>59</height> <jobDescription>manager</jobDescription> </person> </staffRecord> xsd file: <xs:element name="staffRecord"> <xs:complexType> <xs:sequence> <xs:element name="company" type="xs:string"/> <xs:element name="dpt" type="xs:string"/> <xs:element name="person" type="Person"/> <xs:complexType name="Person" abstract="true"> <xs:sequence> <xs:element name= "name" type="xs:string"/> <xs:element name= "height" type="xs:double" /> </xs:sequence> </xs:complexType> <xs:complexType name="Employee"> <xs:complexContent> <xs:extension base="Person"> <xs:sequence> <xs:element name="jobDescription" type="xs:string" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> </xs:sequence> </xs:complexType> </xs:element> When validating the xml with that schema with xmllint (under linux), I get this error message then: config.xsd:12: element complexType: Schemas parser error : Element '{http://www.w3.org/2001/XMLSchema}sequence': The content is not valid.

  • Should I create a unique clustered index, or non-unique clustered index on this SQL 2005 table?

    - by Bremer
    I have a table storing millions of rows. It looks something like this: Table_Docs ID, Bigint (Identity col) OutputFileID, int Sequence, int …(many other fields) We find ourselves in a situation where the developer who designed it made the OutputFileID the clustered index. It is not unique. There can be thousands of records with this ID. It has no benefit to any processes using this table, so we plan to remove it. The question, is what to change it to… I have two candidates, the ID identity column is a natural choice. However, we have a process which does a lot of update commands on this table, and it uses the Sequence to do so. The Sequence is non-unique. Most records only contain one, but about 20% can have two or more records with the same Sequence. The INSERT app is a VB6 piece of crud throwing thousands insert commands at the table. The Inserted values are never in any particular order. So the Sequence of one insert may be 12345, and the next could be 12245. I know that this could cause SQL to move a lot of data to keep the clustered index in order. However, the Sequence of the inserts are generally close to being in order. All inserts would take place at the end of the clustered table. Eg: I have 5 million records with Sequence spanning 1 to 5 million. The INSERT app will be inserting sequence’s at the end of that range at any given time. Reordering of the data should be minimal (tens of thousands of records at most). Now, the UPDATE app is our .NET star. It does all UPDATES on the Sequence column. “Update Table_Docs Set Feild1=This, Field2=That…WHERE Sequence =12345” – hundreds of thousands of these a day. The UPDATES are completely and totally, random, touching all points of the table. All other processes are simply doing SELECT’s on this (Web pages). Regular indexes cover those. So my question is, what’s better….a unique clustered index on the ID column, benefiting the INSERT app, or a non-unique clustered index on the Sequence, benefiting the UPDATE app?

  • Burn bootable iso image to USB stick using dd: Won't boot (despite USB first in boot sequence)

    - by Nicolas Raoul
    I have installed Ubuntu on a Lenovo Thinkpad R500 2732, and I must update the BIOS. On the Lenovo website, I am offered this: BIOS Update Bootable CD for Windows 7 (32-bit, 64-bit), Vista (32-bit, 64-bit), XP - ThinkPad R500 I guess a bootable CD that would do a BIOS update is indeed what I need. (still wondering why it says "Windows" though... if it is bootable should not it be OS-agnostic?) Not wanting to waste a CD, I copied the image to my USB stick: sudo dd if=/home/nico/7yuj40uc.iso of=/dev/sdb1 bs=1M And rebooted, after making sure USB is first in the boot sequence. PROBLEM: It does not boot. Did I forget one step? Details about the iso image (readme): ls -lh 7yuj40uc.iso 25M file 7yuj40uc.iso /home/nico/7yuj40uc.iso: # ISO 9660 CD-ROM filesystem data '7YUJ40US ' (bootable) (Scroll to the right: it says "bootable") UNetbootin does not work because it is not a Linux image. Some people on the Internet advise to copy the content of the ISO and do other steps. This ISO has zero ISO content so it would not work. If I mount the ISO, I can see it contains zero files.

  • UIScrollView. Any thoughts on implementing "infinite" scroll/zoom?

    - by dugla
    So, UITableView supports essentially "infinite" scrolling. There' may be a limit but that sucker can scroll for a looonnnggg time. I would like to mimic this behavior with a UIScrollView but there are two fundamental impediments: 1) scrollView.contentSize is fixed at creation time. 2) zooming can blow any lazy-loading scheme all to hell since it can cause infinte data explosion. Have others out there pondered this idea? Yah, I know, we are essentially talking about re-creating Google Maps here. Any insights would be much appreciated. Cheers, Doug

  • How do I avoid an infinite loop when overriding a virtual property?

    - by cbsch
    Is it possible to ignore set and get when I'm assigning to or retrieving a value? In specific, I'm inheriting from a class that has a property declared like this: virtual public Int32 Value { get; set; } What I'd like to do is to override it and do something useful in those set and get's. The problem appears when I override it, I also have to manually assign, or return the value from the property. If I do something like this: override public Int32 Value { get { return this.Value; } set { this.Value = value; // do something useful } Then I'm creating an infinite loop. Is there a way to set or get the value without invoking the code in set and get, or do I have to make a separate name for the actual variable?

  • Pass potentially infinite number of arguments to array except a single numeric variable in a PHP com

    - by tehalive
    I'm trying to make a PHP script that will take a potentially infinite number of URLs from the command line as arguments. I also need to pass an argument that only has a single numeric value possible (to specify timeout), e.g.: ./urltest.php 60 url1.com url2.com url3.com I'm not exactly sure how to specify argv[1] to be a single numeric variable while at the same time the rest of the arguments (i.e. the list of urls) go into an array. Maybe something like: $timeout = $argv[1]; $args = func_get_args(); function numfilter($num) { return !is_numeric($num); } $urls = array_filters($args, 'numfilter'); ? Thanks in advance!

  • Why doesn't infinite recursion hit a stack overflow exception in F#?

    - by Amazingant
    I know this is somewhat the reverse of the issue people are having when they ask about a stack overflow issue, but if I create a function and call it as follows, I never receive any errors, and the application simply grinds up a core of my CPU until I force-quit it: let rec recursionTest x = recursionTest x recursionTest 1 Of course I can change this out so it actually does something like this: let rec recursionTest (x: uint64) = recursionTest (x + 1UL) recursionTest 0UL This way I can occasionally put a breakpoint in my code and see the value of x is going up rather quickly, but it still doesn't complain. Does F# not mind infinite recursion?

  • How do I simulate the usage of a sequence of web pages?

    - by Rory Becker
    I have a simple sequence of web pages written in ASP.Net 3.5 SP1. Page1 - A Logon Form.... txtUsername, txtPassword and cmdLogon Page2 - A Menu (created using DevExpress ASP.Net controls) Page3 - The page redirected to by the server in the event that the user picks the right menu option in Page2 I would like to create a threaded program to simulate many users trying to use this sequence of pages. I have managed to create a host Winforms app which Launches a new thread for each "User" I have further managed to work out the basics of WebRequest enough to perform a request which retrieves the Logon page itself. Dim Request As HttpWebRequest = TryCast(WebRequest.Create("http://MyURL/Logon.aspx"), HttpWebRequest) Dim Response As HttpWebResponse = TryCast(Request.GetResponse(), HttpWebResponse) Dim ResponseStream As StreamReader = New StreamReader(Response.GetResponseStream(), Encoding.GetEncoding(1252)) Dim HTMLResponse As String = ResponseStream.ReadToEnd() Response.Close() ResponseStream.Close() Next I need to simulate the user having entered information into the 2 TextBoxes and pressing logon.... I have a hunch this requires me to add the right sort of "PostData" to the request. before submitting. However I'm also concerned that "ViewState" may be an issue. Am I correct regarding the PostData? How do I add the postData to the request? Do I need to be concerned about Viewstate? Update: While I appreciate that Selenium or similar products are useful for acceptance testing , I find that they are rather clumsy for what amounts to load testing. I would prefer not to load 100 instances of Firefox or IE in order to simulate 100 users hitting my site. This was the reason I was hoping to take the ASPNet HttpWebRequest route.

  • iphone - keeping the last frame of a frame animation visible

    - by Mike
    I have this code UIImageView *sequence = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"balao_surge0.png"]]; NSMutableArray *array = [[NSMutableArray alloc] init] ; for (int i=0; i<30; i++) { UIImage *oneImage = [UIImage imageNamed:[NSString stringWithFormat:@"balao_surge%d.png",i]]; [array addObject:oneImage]; } sequence.animationImages = array; sequence.animationDuration = 2.0; sequence.animationRepeatCount = 1; [umaVista addSubview:sequence]; [sequence release]; sequence.startAnimating; The animation plays fine, but after the last frame is shown, it vanishes. I would like to make it stay visible, that is, make the animation stop on the last frame. Is there any way to do that? thanks for any help.

  • Python structure mistake

    - by jaddy123
    I'm writing a program in which I can Reverse the sequence and Replace all As with Ts, all Cs with Gs, all Gs with Cs, and all Ts with As. the program is to read a sequence of bases and output the reverse complement sequence. I am having trouble to do it so can anyone please help me with this by having a look on my code: word = raw_input("Enter sequence: ") a = word.replace('A', 'T') b = word.replace('C', 'G') c = word.replace('G', 'C') d = word.replace('T', 'A') if a == word and b == word and c == word and d == word: print "Reverse complement sequence: ", word And I want this sort of output: Enter sequence: CGGTGATGCAAGG Reverse complement sequence: CCTTGCATCACCG Regards

  • Why does this javascript code have an infinite loop?

    - by asdas
    optionElements is a 2d array. Each element has an array of length 2. These are an integer number and an element. I have a select list called linkbox, and i want to add all of the elements to the select list. The order I want them to go in is important, and is determined by the number each element has. It should be smallest to highest. So think of it like this: optionElements is: [ [5, <option>], [3, <option], [4, <option], [1, <option], [2, <option]] and it would add them to link box in order of those numbers. BUT that is not what happens. It is an infinite loop after the first time. I added the x constraint just to stop it from freezing my browser but you can ignore it. var b; var smallest; var samllestIndex; var x = 0; while(optionElements.length > 0 && ++x < 100) { smallestIndex = 0; smallest = optionElements[0][0]; b = 0; while( ++b < optionElements.length) { if(optionElements[b][0] > smallest) { smallestIndex = b; smallest = optionElements[b][0]; } } linkbox.appendChild(optionElements[smallestIndex][1]); optionElements.unshift(optionElements[smallestIndex]); } can someone point out to me where my problem is?

  • How to stop a infinite running process(ztail) started by a ssh session after that session is closed

    - by Sanath Adiga
    I have a peculiar problem. My server supports multiple ssh session simultaneously, so that multiple admins can manage it simultaneously. We have a command which calls ztail to show the compressed log files and when the current ssh session is closed (without pressing ctrlc, to stop the tail command), the command should ideally stop working. But what I observed when I start a new ssh session is that the process ztail is still running in the background and consuming CPU, even though the previous session was closed. How can I determine when the session is closed, so that I can use that variable/flag to close/stop any commands initiated by that previously closed session?

  • Is this method pure?

    - by Thomas Levesque
    I have the following extension method: public static IEnumerable<T> Apply<T>( [NotNull] this IEnumerable<T> source, [NotNull] Action<T> action) where T : class { source.CheckArgumentNull("source"); action.CheckArgumentNull("action"); return source.ApplyIterator(action); } private static IEnumerable<T> ApplyIterator<T>(this IEnumerable<T> source, Action<T> action) where T : class { foreach (var item in source) { action(item); yield return item; } } It just applies an action to each item of the sequence before returning it. I was wondering if I should apply the Pure attribute (from Resharper annotations) to this method, and I can see arguments for and against it. Pros: strictly speaking, it is pure; just calling it on a sequence doesn't alter the sequence (it returns a new sequence) or make any observable state change calling it without using the result is clearly a mistake, since it has no effect unless the sequence is enumerated, so I'd like Resharper to warn me if I do that. Cons: even though the Apply method itself is pure, enumerating the resulting sequence will make observable state changes (which is the point of the method). For instance, items.Apply(i => i.Count++) will change the values of the items every time it's enumerated. So applying the Pure attribute is probably misleading... What do you think? Should I apply the attribute or not?
