• Exclude nodes based on attribute wildcard in XSL node selection

  - by C A

  Using cruisecontrol for continuous integration, I have some annoyances with Weblogic Ant tasks and how they think that server debug information are warnings rather than debug, so are shown in my build report emails. The XML output from cruise is similar to: <cruisecontrol> <build> <target name="compile-xxx"> <task name="xxx" /> </target> <target name="xxx.weblogic"> <task name="wldeploy"> <message priority="warn">Message which isn't really a warning"</message> </task> </target> </build> </cruisecontrol> In the cruisecontrol XSL template the current selection for the task list is: <xsl:variable name="tasklist" select="/cruisecontrol/build//target/task"/> What I would like is something which selects the tasklist in the same way, but doesn't include any target nodes which have the attribute name="*weblogic" where * is a wildcard. I have tried <xsl:variable name="tasklist" select="/cruisecontrol/build//target[@name!='*weblogic']/task"/> but this doesn't seem to have worked. I'm not an expert with XSLT, and just want to get this fixed so I can carry on the real development of the project. Any help is much appreciated.

• Simple stream read/write question in java

  - by Marius

  Hi, I'm trying to upload a file via URLConnection, but i need to read/write it as a binary file without any encoding changes. So i've tried to read byte[] array from FileInputStream, but now i have an issue. The PrintWriter object i use for outputing to the server does not allow me to do writer.write(content) (where content is of type byte[]). How can i fix this? Or is there another way to quickly copy binary data from a FileInputStream to a PrintWriter? Thank you

• T-SQL Specific Syntax problem (Simple no doubt)

  - by Yoda

  Hi guys, I have an issue with a query I'm trying to run on some data, I guess the place to start is to describe the data. Ok so I have a list of email addresses, each email address has a unique ID and an account ID Also in my tables I have a set number which auto incrememnts, this will allow me to target duplicate email addresses What I need to do is something like this. Insert into duplicates (EMAIL,ACCOUNTID,ID) SELECT Email,AccountID,ID FROM EmailAddresses Group by Email,AccountID Having Count(email)>1 Order by AccountID, Email So essentially I want to select all duplicate email addresses and insert them (and their relative fields) into a new table broken down by accountID so I can run some further querys on it. I have been battling with this for way too long and could just use a fresh perspective. Cheers in advance

• matlab: simple matrix filtering - group size

  - by Art

  I have a huuuge matrix storing information about X and Y coordinates of multiple particle trajectories , which in simplified version looks like that: col 1- track number; col 2- frame number; col 2- coordinate X; col 3- coordinate Y for example: A = 1 1 5.14832 3.36128 1 2 5.02768 3.60944 1 3 4.85856 3.81616 1 4 5.17424 4.08384 2 1 2.02928 18.47536 2 2 2.064 18.5464 3 1 8.19648 5.31056 3 2 8.04848 5.33568 3 3 7.82016 5.29088 3 4 7.80464 5.31632 3 5 7.68256 5.4624 3 6 7.62592 5.572 Now I want to filter out trajectories shorter than lets say 2 and keep remaining stuff like (note renumbering of trajectories): B = 1 1 5.14832 3.36128 1 2 5.02768 3.60944 1 3 4.85856 3.81616 1 4 5.17424 4.08384 2 1 8.19648 5.31056 2 2 8.04848 5.33568 2 3 7.82016 5.29088 2 4 7.80464 5.31632 2 5 7.68256 5.4624 2 6 7.62592 5.572 How to do it efficiently? I can think about some ideas using for loop and vertcat, but its the slowest solution ever :/ Thanks!

• Writing a simple incrementer counter in rails

  - by Trip

  For every Card, I would like to attach a special number to them that increments by one. I assume I can do this all in the controller. def create @card = Card.new(params[:card]) @card.SpecNum = @card.SpecNum ++ ... end Or. I can be blatantly retarded. And maybe the best bet is to add an auto-incremement table to mysql. The problem is the number has to start at a specific number, 1020. Any ideas?

• Simple logic in javascript

  - by Saurabh

  I have four variables of type integer - var tip_1, tip_2, tip_3, tip_4; The value of these variables are getting fill by some other logic which is always between 1 to 10. I need to maintain a hash with variable name as "key" and value as "value" by following these rules - The variable with MAX value should be the first element in the hash and so on. e.g. if tip_1 = 4, tip_2 = 1, tip_3 = 2, tip_4 = 10 then hash should be something like, Hash = {tip_4, 10} {tip_1, 4} {tip_3, 2} {tip_1, 1} In case of tie following order should be considered - tip_1 tip_2 tip_3 tip_4;

• How to make a simple Wine-based installer for Windows application

  - by zarawesome

  My Windows application runs under Wine, but the installation is a bit of a headache for laymen, and the wrappers I've seen online (PlayOnLinux, Wine Doors) require even more packages to be installed. Is there a way to make a package that will install Wine if the user needs it to be installed, install the application and shortcuts, all with minimal user hassle?

• Simple graphics import and manipulation

  - by gnuboi

  What do I need to do something like this? User builds a diagram and tags certain boxes and circles with text. User imports diagram into my program. My program processes the tagged boxes and circles and fills them with different colors. My program exports color-filled diagram. So the questions are... What graphics format supports tag-able boxes and circles? What existing application should I recommend users to use to produce diagrams in the above format? Would this graphics format be very easily readable in code to do things like reading tags and coloring in the associated boxes and circles? Free / open source libraries and apps are desired as this would be for academic use. Thank you!

• simple method that checks text is email with regular expression

  - by user223863

  Can't believe how difficult this seems to be all I want to is to validate a user inout using javascript to make sure that it is an email address. But can't get it to work: I am using: //validates a regulaer expression Utilities2.prototype.validateEmail = function(stringToValidateArg) { alert('about to check regexp'); var regExpPattern = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/; alert(regExpPattern.test(stringToValidateArg)); } But this always returns false, any ideas why is it because of the regular expression?

  - by Kyle Noland

• C program giving incorrect output for simple math!

  - by DuffDuff

  (all are declared as ints, none are initialized to anything beforehand. I have included math.h and am compiling with -lm) cachesize = atoi(argv[1]); blocksize = atoi(argv[3]); setnumber = (cachesize/blocksize); printf("setnumber: %d\n", setnumber); setbits = (log(setnumber))/(log(2)); printf("sbits: %d\n", setbits); when given cachesize as 1024 and blocksize as 16 the output is as follows: setnumber: 64 sbits: 5 but log(64)/log(2) = 6 ! It works correctly when given cachesize 512 and blocksize 32. I can't seem to win. I'm really hoping that it's a stupid mistake on my part, and I'd be grateful if anyone could point out what it is! Thank you! PS: I posted this in Yahoo Answers first but that was probably silly. Won't be doing that again.

  Hi. Can anyone point out how to check if a select query returns non empty result set? For example I have next query: SELECT * FROM service s WHERE s.service_id = ?; Should I do something like next: ISNULL(SELECT * FROM service s WHERE s.service_id = ?) to test if result set is not empty?

• Looking for a mobile platform to view vector data and use it like a simple map

  - by Orchestrator

  I would like to develop or use an existing platform that will allow me to view custom vector data and use it as a map on mobile phones such as Android/IPhone (Maybe even WP7). I'm hoping that there's already a good infrastructure for what I need so I would not need to develop a whole infrastructure by myself. In Conclusion - Is there any existing platform that may answer my needs? If not, how would you guys suggest I should begin? How should I save my vector data? How could I read it? Should I view it with a graphics engine like OpenGL? Is there any chance this solution could be cross-platform? I know that it's possible since it was already done with apps like Waze. And it works the same on iOS and Android. Thanks!

• Simple PHP query question: LIKE

  - by pg

  When I replace $ordering = "apples, bananas, cranberries, grapes"; with $ordering = "apples, bananas, grapes"; I no longer want cranberries to be returned by my query, which I've written out like this: $query = "SELECT * from dbname where FruitName LIKE '$ordering'"; Of Course this doesn't work, because I used LIKE wrong. I've read through various manuals that describe how to use LIKE and it doesn't quite make sense to me. If I change the end of the db to "LIKE "apples"" that works for limiting it to just apples. Do I have to explode the ordering on the ", " or is there a way to do this in the query?

• What type of data store should I use for my ios app?

  - by mwiederrecht

  I am pretty new to ios and using servers so forgive me. I am building an ios app for research. I need to monitor things that the user does and then push it up to a server for analysis (yes, with user and IRB permission). On the client's side I need to keep quite a bit of data that won't really change except in the case of pulling an updated version from the server, and then a minimal amount of user-specific data. Most of the data I will collect needs to be pushed to a server for analysis and then can be deleted from the client side. I am struggling to figure out what kind of data store I need to use, especially since I am not quite sure how the pushing and pulling from the server process works yet. Does it make sense to use Core Data? XML? SQLite? I like the Core Data idea, but I am not sure what kind of problems I will run into when I need to send large amounts of data to it and from it from the server. I imagine I might need to send data in a different form than it is probably stored in on either end - so what kind of overhead am I likely to run into in the process of converting that data? Is there a good format to save stuff in that would work well for me on both ends AND for sending the data? As you can probably tell, I could use some advice. Thanks!
