  • DB2 load partitioned data in parallel

    - by Erik Paulson
    I have a 10-node DB2 9.5 database, with raw data on each machine (ie node1:/scratch/data/dataset.1 node2:/scratch/data/dataset.2 ... node10:/scratch/data/dataset.10 There is no shared NFS mount - none of my machines could handle all of the datasets combined. each line of a dataset file is a long string of text, column delimited. The first column is the key. I don't know the hash function that DB2 will use, so dataset is not pre-partitioned. Short of renaming all of my files, is there any way to get DB2 to load them all in parallel? I'm trying to do something like load from '/scratch/data/dataset' of del modified by coldel| fastparse messages /dev/null replace into TESTDB.data_table part_file_location '/scratch/data'; but I have no idea how to suggest to db2 that it should look for dataset.1 on the first node, etc.

  • Is there a bash shortcut for traversing similar directory structures?

    - by Steve Weet
    The Korn shell used to have a very useful option to cd for traversing similar directory structures e.g. given the following directorys /home/sweet/dev/projects/trunk/projecta/app/models /home/andy/dev/projects/trunk/projecta/app/models Then if you were in the /home/sweet.... directory then you could change to the equivalent directory in andy's structure by typing cd sweet andy So if ksh saw 2 arguments then it would scan the current directory path for the first value, replace it with the second and cd there. Is anyone aware of similar functionality in bash. EDIT 1 Following on from Michal's excellent answer I have now created the following bash function called scd (For Sideways cd) function scd { cd "${PWD/$1/$2}" } EDIT 2 Thanks to @digitalross I can now reproduce the ksh functionality exactly with the code from below (With the addition of a pwd to tell you where you have changed to) cd () { if [ "x$2" != x ]; then builtin cd ${PWD/$1/$2} pwd else builtin cd "$@" fi }

  • How is your mac setup for windows development?

    - by Matt Brailsford
    Hi Guys, I'm looking at buying a MacBook Pro to replace my tiring laptop. My day to day job is as a .NET web developer so I am looking to use VMWare Fusion to run VS and SQL server etc. As I've not run my dev environment in a VM before, I would like to know how others are setup. What apps to you have installed? In which environment? Where do you store your files? Within each environment, or some shared drive? Are there any gotchas? Or essentials I should know. Many thanks Matt

  • How do you change the subdocument location in a Word 2007 master document programmatically?

    - by boost
    We have had the unenviable happen: various master documents refer to sub-documents that are no longer where they used to be due to a directory renaming. Is there a programmatic way of tweaking the HYPERLINK field without losing the master/sub-document relationship? I've got this far ... Sub FixyaLinks() Dim s 'As String Dim i As Long Dim bTrackRevFlag As Boolean Dim bShowRevFlag As Boolean bTrackRevFlag = ActiveDocument.TrackRevisions bShowRevFlag = ActiveDocument.ShowRevisions ActiveDocument.TrackRevisions = False ActiveDocument.ShowRevisions = False For i = 1 To ActiveDocument.Fields.Count s = ActiveDocument.Fields.Item(i).Code.Text If InStr(s, "CURRICULUM\\NEW") Then s = Replace(s, "NEW Foundation Units-in developing", "Foundation Programme Units") ActiveDocument.Fields.Item(i).Code.Text = s End If Next ActiveDocument.TrackRevisions = bTrackRevFlag ActiveDocument.ShowRevisions = bShowRevFlag End Sub It bombs on ActiveDocument.Fields.Item(i).Code.Text = s, with an error 5686 ("The operation cannot be completed because the Track Changes option in the master document does not match the option the the subdocument. Make the Track Changes option the same in the master document and subdocument.") However, I'm not entirely sure what that means. Ideas anyone?

  • Compilers behave differently with a null parameter of a generic method

    - by Eyal Schneider
    The following code compiles perfectly with Eclipse, but fails to compile with javac: public class HowBizarre { public static <P extends Number, T extends P> void doIt(P value) { } public static void main(String[] args) { doIt(null); } } I simplified the code, so T is not used at all now. Still, I don't see a reason for the error. For some reason javac decides that T stands for Object, and then complains that Object does not conform to the bounds of T (which is true): HowBizarre.java:6: incompatible types; inferred type argument(s) java.lang.Number,java.lang.Object do not conform to bounds of type variable (s) P,T found : <P,T>void required: void doIt(null); ^ Note that if I replace the null parameter with a non-null value, it compiles fine. Which of the compilers behaves correctly and why? Is this a bug of one of them?

  • Write a function that returns the longest palindrome in a given string. e.g "ccddcc" in the string "

    - by Learner
    I thought of a solution but it runs in O(n^2) time Algo 1: Steps: Its a brute force method Have 2 for loops for i = 1 to i less than array.length -1 for j=i+1 to j less than array.length This way you can get substring of every possible combination from the array Have a palindrome function which checks if a string is palindrome so for every substring (i,j) call this function, if it is a palindrome store it in a string variable If you find next palindrome substring and if it is greater than the current one, replace it with current one. Finally your string variable will have the answer Issues: 1. This algo runs in O(n^2) time. Algo 2: Reverse the string and store it in diferent array Now find the largest matching substring between both the array But this too runs in O(n^2) time Can you guys think of an algo which runs in a better time. If possible O(n) time

  • ASP MVC 2 : Custom display of a required form element based on ModelMetaData

    - by Nigel
    I have an MVC 2 application that utilises forms. The required fields within the form are set using attributes that update the model metadata. The form fields are created using the MVC HtmlHelper method : Html.EditorFor. This works fine so far as validation is concerned, but it seems that by default the required fields are not displayed to the user (for example by appending a * to the control). If I wanted to provide some custom means of displaying this fact to the user (lets immagine I want to change the background colour of the edit control for example), where is the best place to do it. Would I need to create a custom html helper to replace EditorFor? I tried but it seemed difficult to gain access to the metadata for the correct property. I already have a custom ModelMetaDataProvider so there is no problem adding it there if that is the correct place.

  • php Set a anonymous function in an instance

    - by geekay
    I am just starting out with PHP, and I am wondering if there is a way to add an anonymous function to a class instance. For instance, lets say... class A{ public B; } $c = new A(); //This is where I am getting a little confused... //The following wont work $c->B = function(){echo('HelloWorld');}; $c->B(); What I am hoping to do is reuse the same spit of code in a great number of different applications, and make it so that I can just 'swap-out' and replace functions in specific instances. I am using php5.3 (so anonymous functions should work, just not in the way that I am using them). Thanks so very much for your time!! -GK

  • How do I make a specific word (variable) in a message box bold in Java?

    - by typoknig
    Hi all, I'm trying to make one word (variable) of a message box bold in my Java program. Here is my code: int n = messageBox.showConfirmDialog(frame, "The File "+ file +" already exists." + "\n" + "Do you want to replace it?", "File Already Exists!", messageBox.YES_NO_OPTION); I want to make the variable "file" appear in bold text in my message box. So far I have only been able to get the entire message box to appear in bold, or none of it at all. How do I do this?

  • Converting HTML special characters into their value using Python

    - by tipu
    I have a file that's littered with these: http://www.utexas.edu/learn/html/spchar.html That link just displays all sorts of HTML entities, such as – &ndash; — &mdash; ¡ &iexcl; and so on. Is it possible in Python to natively convert these characters back into their values so any occurrences of &ndash; will appear as – instead? My current approach was just to make a dict of key html entities and their utf-8 values and do search and replace, but I was wondering if there are any libraries that can take care of this for me.

  • Unsuccessful error detection of improperly declared method in GCC 4.2 compiler

    - by sam
    I am using C++ compiler GCC 4.2 in XCode 3.2.2. I have noted that the compiler will successfully compile a method foo even though there are no ellipses. The header and method are properly declared as foo(), but when I do a find and replace either by file or by program-wide it will miss approximately 2-3% of the changes [foo to foo(). This would not be critical if the compiler did not give an erroneous successful build. I have not found that this to occur with: foo(any parameter). Does anyone have any solution? Thank you.

  • Stack allocation fails and heap allocation succeeds!! Is it possible??

    - by Prabhu
    Hello All, I have the following piece of snippet Class Sample { Obj_Class1 o1; Obj_Class2 o2;}; But the size of Obj_Class1 and Obj_Class2 is huge so that the compiler shows a warning "Consider moving some space to heap". I was asked to replace Obj_Class1 o1 with Obj_Class1* o1 = new Obj_Class1(); But I feel that there is no use of making this change as heap allocation will also fail if stack allocation fails. Am I correct? Or does it make sense to make this change ( other than suppressing the compiler warning ).

  • Regex for url formatting (www.domain.tld to anchors)

    - by Kristaps
    Hi. I'm currently developing a little browser-based Twitter widget. Currently, I'm stuck with getting the URLs to work. I'm kinda newbie, when it comes to regex (I know, how to get parts of a string, but this one – tough one). So, I need a regex that would search/replace www.domain.tld -> <a href="http://www.domain.tld">http://www.domain.tld</a> With/without http://, preferably. Any advice is welcome. Thanks.

  • Fade effect onclick (jQuery)

    - by Nimbuz
    I have this very basic tabbed block: $('.tabbed-section .panel').hide(); $('.tabbed-section .panel:first').show(); $('.tabbed-section .tabs li:first').addClass('active'); $('.tabbed-section .tabs li a').click(function () { $('.tabbed-section .tabs li').removeClass('active'); $(this).parent().addClass('active'); var currentTab = $(this).attr('href'); var tab_id = $(this).attr('href'); $(this).closest('#hero').attr('class', 'clear ' + tab_id.replace('#', '')); $('.tabbed-section .panel').hide(); $(currentTab).show(); return false; }); .. it works great, but can I add fade effect when the active tab changes? I think there's a plugin (innerfade) for it but I want to avoid using another plugin if possible. Also, can the jQuery above be compacted further? Thanks for your help!

  • How to call angular javascript directive methods from the global scope

    - by user1659278
    I have a directive like the one of the examples from AngularJS, shown below. How can I call the toggle method from the global scope? I want to be able to toggle the zippy from some legacy code. myApp.directive('zippy', function(){ return { restrict: 'E', replace: true, transclude: true, scope: { title:'bind' }, template: '<div class="zippy">' + '<div class="title">{{title}}</div>' + '<div class="body" ng-transclude></div>' + '</div>', link: function(scope, element, attrs) { var title = angular.element(element.children()[0]), opened = true; title.bind('click', toggle); function toggle() { opened = !opened; element.removeClass(opened ? 'closed' : 'opened'); element.addClass(opened ? 'opened' : 'closed'); } toggle(); } } });

  • jQuery, drop image on overlaping target

    - by Cinaird
    I am using jQuery to detect drop on target, the target in question is a image. If i drag one image upon another, and then drop it, it shall replace the target source with the dropped source. This works fine until two images lies upon each other. Some of the images lies next to each other and some times the target images overlap. if i drop, both the visible image and the image beneath is replaced with the dragged image. I hope the problem is clear and their is any good solution

  • Should I trust Redis for data integrity?

    - by Jiaji
    In my current project, I have PostgreSQL as my master DB, and Redis as kind of a slave, e.g., when some user adds another as a friend, first the relationship will be stored in PostgreSQL and then a friend list in Redis will be updated. When some user's friend list is requested, it will be pulled out of Redis instead of PostgreSQL. The question is: when I update the friend list in Redis, should I get a fresh copy outof PostgreSQL, and replace the old list in Redis with the new one or should I keep the old list and simply SADD the userid into the list? The latter is of course best for performance, but intuitively the former does a better job in keep the data integrity? And if something like Celery is used, is the second method worth the risk?

  • Double-Escaped Unicode Javascript Issue

    - by Jeffrey Winter
    I am having a problem displaying a Javascript string with embedded Unicode character escape sequences (\uXXXX) where the initial "\" character is itself escaped as "&#92;" What do I need to do to transform the string so that it properly evaluates the escape sequences and produces output with the correct Unicode character? For example, I am dealing with input such as: "this is a &#92;u201ctest&#92;u201d"; attempting to decode the "&#92;" using a regex expression, e.g.: var out = text.replace('/&#92;/g','\'); results in the output text: "this is a \u201ctest\u201d"; that is, the Unicode escape sequences are displayed as actual escape sequences, not the double quote characters I would like.

  • Eidetic memory: What magic numbers you still remember?

    - by Hao
    Long before you practice writing readable code, what "magic numbers" you still remember up to this day? here's some of my list: 72 80 75 77 13 32 27 - up down left right enter space escape 1 2 4 128 - blue green red blink 67h 33h 17h - interrupt for EMS, mouse, printer function AH 9, interrupt 21 alt+219 for block ASCII alt+164 ñ 90 NOP 13 10 carriage return, line feed ascii 1 and 2 face, ascii 3 heart. no not this heart: <3 :-) debug -o72,10 -o71,12 clears the BIOS password. I don't know what those numbers mean, it's like a trade secret that gets shared with each other during college days. ascii 7 sounds a beep P.S. Somehow, remembering some of these magic numbers can help you in some tech problems, your keyboard is broken, the office pal's keyboard doesn't have accented characters. An anecdote, during college, one of my friend asked me how to remove the newlines in his Word document. Not having used Word so much then, I somehow "intuitively" guessed to find ^013 and replace it with blank. Well it works :-)

  • Injecting an XML fragment into the current document from an external file

    - by makenai
    I'm currently parsing an XML file using REXML and trying to come up with a way of inserting an XML fragment from an internal file. Currently, I'm using some logic like the following: doc.elements.each('//include') do |element| handleInclude( element ) end def handleInclude( element ) if filename = element.attributes['file'] data = File.open( filename ).read doc = REXML::Document.new( data ) element.parent.replace_child( element, doc ) end end Where my XML looks like the following: <include file="test.xml" /> But this seems a little bit clunky, and I'm worried that REXML might not always parse XML fragments correctly due to absence of a proper root node in some cases. Is there a better way of doing this? Concern #2: REXML seems not to pick up my changes after I replace elements. For example, after making a change: doc.elements.each('rootNode/*') do |element| end ..picks up neither the original element I replaced, nor the one I replaced it with. Is there some trick to getting REXML to rescan its' tree?

  • MySQL: updating a row and deleting the original in case it becomes a duplicate

    - by Silvio Donnini
    I have a simple table made up of two columns: col_A and col_B. The primary key is defined over both. I need to update some rows and assign to col_A values that may generate duplicates, for example: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 This statement sometimes yields a duplicate key error. I don't want to simply ignore the error with UPDATE IGNORE, because then the rows that generate the error would remain unchanged. Instead, I want them to be deleted when they would conflict with another row after they have been updated I'd like to write something like: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 ON DUPLICATE KEY REPLACE which unfortunately isn't legal in SQL, so I need help finding another way around. Also, I'm using PHP and could consider a hybrid solution (i.e. part query part php code), but keep in mind that I have to perform this updating operation many millions of times. thanks for your attention, Silvio Reminder: UPDATE's syntax has problems with joins with the same table that is being updated

  • How to update individual files in a war file

    - by ziggy
    Hi guys, I am doing some research in the way i can deploy an application efficiently using a war file. What i currently do is i deliver the war file everytime there is a release. This means everytime there is a change no matter how small the change is i have to build and deliver all files that make up the application. I am thinking that maybe this is not the correct way to do this. For example if there is a change to a css file i have to rebuild the war file which will include all file. This includes recompiling all *.java files as well. In the above example, is it possible to build a war file with just the css file and deploy it to the tomcat server and have Tomcat just replace the css file and leave everything else as is?
