  • gwt seperate modules with no code sharing

    - by Code freak
    Hi, I have to make a web application using GWT. The project has a core module that'll expose a set of apis to be used by other apps; each of these app are unrelated. Each shall be loaded in a separate iframe. My idea was to compile core into core.js and each app shall have its own app1.js app2.js and so on... App1 script type="text/javascript" src="core.js" ></script> script type="text/javascript" src="app1.js" ></script> with this design, due to browser caching, each app laod only the app.js which should be smaller ~20kb in size. Making a core module is straightforward but the apps are problematic. The reason being after compilation, each app contains the entire GWT library - this substantially increases the download size of the complete webapp. Can anyone suggest a way to get aroung this problem ? I've checked similar questions on SO, but failed to find a simple working answer fr the problem. Thanks for any help.

  • Python script names in tasklist

    - by Richard
    I am wondering, is there a way to change the name of a script so that it is not called "python.exe" in the tasklist. The reason I am asking is that I am trying to make a batch file that run's a python script. I want the batch file to check to see if the script is already running. if the script is already running then the batch file will do nothing. Thanks

  • Linux file names & file globbing

    - by John Lelos
    I have a list of files named: file000 file001 file002 file003 ... file1100 How can I match all files that have a number greater than 800 but less than 1000 ? I am using linux bash Thank you Edit Actually, my files are named like: ab869.enc cp936.enc g122345.enc x2022.enc abc8859-14.enc aax5601.enc cp936-1.enc so the first solution dont match the correct files :( How can I match files that have number between 800-999 ?

  • Adding file names to an array list in java

    - by Chris G
    Hi I am currently needing to load the contents of a folders filenames to an arraylist I have but I am unsure as how to do this. To put it into perspective I have a folder with One.txt, Two.txt, Three.txt etc. I want to be able to load this list into an arraylist so that if I was to check the arraylist its contents would be : arraylist[0] = One arraylist[1] = Two arraylist[3] = Three If anyone could give me any insight into this it would be much appreciated.

  • Python: replace urls with title names from a string

    - by Hellnar
    Hello I would like to remove urls from a string replace them with their titles of the original contents. For example: mystring = "Ah I like this site: http://www.stackoverflow.com. Also I must say I like http://www.digg.com" sanitize(mystring) # it becomes "Ah I like this site: Stack Overflow. Also I must say I like Digg - The Latest News Headlines, Videos and Images" For replacing url to the title, I have written this snipplet: #get_title: string -> string def get_title(url): """Returns the title of the input URL""" output = BeautifulSoup.BeautifulSoup(urllib.urlopen(url)) return output.title.string

  • postgresql duplicate table names best practice

    - by veilig
    My company has a handful of apps that we deploy in the websites we build. Recently a very old app needed to be included along side a newer app and there was a conflict w/ a duplicate table name needed to be used by both apps. We are now in the process of updating an old app and there will be some DB updates. I'm curious what people consider best practice (or how do you do it) to help ensure these name collisions don't happen. I've looked at schema's but not sure if thats the right path we want to take. As the documentation prescribes, I don't want to "wire" a particular schema name into an application and if I add schema's to the user search path how would it know which table I was referring to if two schema's have the same table name. although, maybe I'm reading to much into this. Any insights or words of wisdom would be greatly appreciated!

  • Is there a website to lookup already common code functions?

    - by pinnacler
    I'm sitting here writing a function that I'm positive has been written before, somewhere on earth. It's just too common to have not been attempted, and I'm wondering why I can't just go to a website and search for a function that I can then copy and paste into my project in 2 seconds, instead of wasting my day reinventing the wheel. Sure there are certain libraries you can use, but where do you find these libraries and when they are absent, is there a site like I'm describing?

  • Compromising design & code quality to integrate with existing modules

    - by filip-fku
    Greetings! I inherited a C#.NET application I have been extending and improving for a while now. Overall it was obviously a rush-job (or whoever wrote it was seemingly less competent than myself). The app pulls some data from an embedded device & displays and manipulates it. At the core is a communications thread in the main application form which executes a 600+ lines of code method which calls functions all over the place, implementing a state machine - lots of if-state-then-do type code. Interaction with the device is done by setting the state/mode globally and letting the thread do it's thing. (This is just one example of the badness of the code - overall it is not very OO-like, it reminds of the style of embedded C code the device firmware is written in). My problem is that this piece of code is central to the application. The software, communications protocol or device firmware are not documented at all. Obviously to carry on with my work I have to interact with this code. What I would like some guidance on, is whether it is worth scrapping this code & trying to piece together something more reasonable from the information I can reverse engineer? I can't decide! The reason I don't want to refactor is because the code already works, and changing it will surely be a long, laborious and unpleasant task. On the flip side, not refactoring means I have to sometimes compromise the design of other modules so that I may call my code from this state machine! I've heard of "If it ain't broke don't fix it!", so I am wondering if it should apply when "it" is influencing the design of future code! Any advice would be appreciated! Thanks!

  • CXF code first service, WSDL generation; soap:address changes?

    - by jcalvert
    I have a simple Java interface/implementation I am exposing via CXF. I have a jaxws element in my Spring configuration file like this: <jaxws:endpoint id="managementServiceJaxws" implementor="#managementService" address="/jaxws/ManagementService" > </jaxws:endpoint> It generates the WSDL from my annotated interface and exposes the service. Then when I hit http://myhostname/cxf/jaxws/ManagementService?wsdl I get a lovely WSDL. At the bottom in the wsdl:service element, I'll see <soap:address location="http://myhostname/cxf/jaxws/ManagementService"/> However, some time a day or so later, with no application restart, hitting that same url produces: This causes a number of problems, but what I really want is to fix it. Right now, there's a particular client to the webservice that sets the endpoint to localhost; because it runs on the same machine. Is it possible the wsdl is getting regenerated and cached and then exposing the 'localhost' version? In part I don't know the exact mechanism by which one goes from a ?wsdl request in CXF to the response. It seems almost certain that it's retrieving some cached version, given that it's supposed to be determining the address by asking the servletcontainer (Jetty). For reference I know a stopgap solution is using the hostname on the client and making sure an alias in place so that it goes over the loopback. EDIT: For reference, I confirmed that if I bring my application up and first hit it over localhost, then querying for the wsdl via the hostname shows the address as localhost. Conversely, first hitting it over the hostname causes localhost requests to show the hostname. So obviously something is getting cached here.

  • Python code, extracting extensions

    - by user1434001
    import os path = '/Users/Marjan/Documents/Nothing/Costco' print path names = os.listdir(path) print len(names) for name in names: print name Here is the code I've been using, it lists all the names in this category in terminal. There are a few filenames in this file (Costco) that don't have .html and _files. I need to pick them out, the only issue is that it has over 2,500 filenames. Need help on a code that will search through this path and pick out all the filenames that don't end with .html or _files. Thanks guys

  • How to write different implicit rules for different file names for GNU Make

    - by anupamsr
    Hi! I have a directory in which I keep adding different C++ source files, and generic Makefile to compile them. This is the content of the Makefile: .PHONY: all clean CXXFLAGS = -pipe -Wall -Wextra -Weffc++ -pedantic -ggdb SRCS = $(wildcard *.cxx) OBJS = $(patsubst %.cxx,%.out,$(SRCS)) all: $(OBJS) clean: rm -fv $(OBJS) %.out: %.cxx $(CXX) $(CXXFLAGS) $^ -o $@ NOTE: As is obvious from above, I am using *.out for executable file extensions (and not for object file). Also, there are some files which are compiled together: g++ file_main.cxx file.cxx -o file_main.out To compile such files, until now I have been adding explicit rules in the Makefile: file_main.out: file_main.cxx file.cxx file.out: file_main.out @echo "Skipping $@" But now my Makefile has a lot of explicit rules, and I would like to replace them with a simpler implicit rule. Any idea how to do it?

  • linux bash script: set date/time variable to auto-update (for inclusion in file names)

    - by user1859492
    Essentially, I have a standard format for file naming conventions. It breaks down to this: target_dateUTC_timeUTC_tool So, for instance, if I run tcpdump on a target of 'foo', then the file would be foo_dateUTC_timeUTC_tcpdump. Simple enough, but a pain for everyone to constantly (and consistently) enter... so I've tried to create a bash script which sets system variables like so: FILENAME=$TARGET\_$UTCTIME\_$TOOL Then, I can just call the variable at runtime, like so: tcpdump -w $FILENAME.lpc All of this works like a champ. I've got a menu-driven .sh which gives the user the options of viewing the current variables as well as setting them... file generation is a breeze. Unfortunately, by setting the date/time variable, it is locked to the value at the time of creation (naturally). I set the variable like so: UTCTIME=$(/bin/date --utc +"%Y%m%d_%H%M%Z") What I really need is either a way to create a variable which updates at runtime, or (more likely) another way to skin this cat. While scouring for solutions, I came across a similar issues... like this. But, to be honest, I'm stumped on how to marry the two approaches and create a simple, distributable solution. I can post the entire .sh if anyone cares to review (about 120 lines)

  • XCode - Multiple targets, Multiple *internationalized* names?

    - by Kris Jenkins
    I've got an internationalized iPhone project. In the various ${lang}.lproj/InfoPlist.strings files I've got a single key, CFBundleName = "My App Name". That's working fine for a single target, but I can't make it work for multiple targets. I'd like to have several translated InfoPlistMyApp.strings files for the main target, plus several InfoPlistMyApp*Lite*.strings files for the lite version. But I can't figure out how to set it up. The InfoPlist.strings name seems to be set in stone, so I can't replace it dynamically. Any ideas?

  • Dynamic where clause in LINQ - with column names available at runtime

    - by sandesh247
    Disclaimer: I've solved the problem using Expressions from System.Linq.Expressions, but I'm still looking for a better/easier way. Consider the following situation : var query = from c in db.Customers where (c.ContactFirstName.Contains("BlackListed") || c.ContactLastName.Contains("BlackListed") || c.Address.Contains("BlackListed")) select c; The columns/attributes that need to be checked against the blacklisted term are only available to me at runtime. How do I generate this dynamic where clause? An additional complication is that the Queryable collection (db.Customers above) is typed to a Queryable of the base class of 'Customer' (say 'Person'), and therefore writing c.Address as above is not an option.

  • Producing dynamically generated range names in Excel using c#

    - by Matey
    What is the best way to produce several tables of unknown size on the same worksheet? Values will be pulled from an oracle database and are used as values on several tables. Is it possible to create dynamic named ranges or is some other method desirable? I have some experience with c# but do not have access to VSTO 2005. Any help or suggestions would be greatly appreciated. I am willing to explain the problem further if requested.

  • REST Rails 2 nested routes without resource names?

    - by mrbrdo
    I'm using Rails 2. I have resources nested like this: - university_categories - universities - studies - professors - comments I wish to use RESTful routes, but I don't want all that clutter in my URL. For example instead of: /universities/:university_id/studies/:study_id/professors/:professor_id I want: /professors/:university_id/:study_id/:professor_id (I don't map professors seperately so there shouldn't be a confusion between this and /professors/:professor_id since that route shouldn't exist). Again, I want to use RESTful resources/routes... Also note, I am using slugs instead of IDs. Slugs for studies are NOT unique, while other are. Also, there are no many-to-many relationships (so if I know the slug of a professor, which is unique, I also know which study and university and category it belongs to, however I still wish this information to be in the URI if possible for SEO, and also it is necessary when adding a new professor). I do however want to use shallow nesting for "administrator" URIs like edit, destroy (note the problem here with Study since it's slug is not unique, though)... I would also like some tips on how to use the url helpers so that I don't have too much to fix if I change the routes in the future... Thank you.

  • Code blocks not linking extension SDL Libraries

    CodeBlocks is not linking extension SDL Libraries like SDL_mixer and SDL_image? I followed Lazy Foo's tutorial for SDL 1.2 but I am compiling my program in SDL 2.0. The compiler is showing an error with the linking of the libraries though without the mixer library it is working. My linker setting look like this. //This is working -lmingw32 -lSDL2main -lSDL2 //But with the additional mixer library it is not working -lmingw32 -lSDL2main -lSDL2 -lSDL_mixer Please help!

  • Package names - impl v internal

    - by Ben J
    In my time of digging around Java APIs I have come across both impl and internal packages. Up until now I never really thought about the difference - as with all enterprisey Java apps, I figured they just meant that "actual implementation in here; you (API user) should be really using the interface. Go away." A little bit of digging around Stack Overflow seems to suggest that the internal package at least can have some security placed around it. So, what is the difference? I don't think it is a matter of taste because I have seen APIs with both.

  • Why does local variable names take precedence over function names in JavaScripts?

    - by fredrik
    In JavaScript you can define function in a bunch of different ways: function BatmanController () { } var BatmanController = function () { } // If you want to be EVIL eval("function BatmanController () {}"); // If you are fancy (function () { function BatmanController () { } }()); By accident I ran across a unexpected behaviour today. When declaring a local variable (in the fancy way) with the same name as function the local variable takes presence inside the local scope. For example: (function () { "use strict"; function BatmanController () { } console.log(typeof BatmanController); // outputs "function" var RobinController = function () { } console.log(typeof RobinController); // outputs "function" var JokerController = 1; function JokerController () { } console.log(typeof JokerController); // outputs "number", Ehm what? }()); Anyone know why var JokerController isn't overwritten by function JokerController? I tested this in Chrome, Safari, Canary, Firefox. I would guess it's due to some "look ahead" JavaScript optimizing done in the V8 and JägerMonkey engines. But is there any technical explanation to explain this behaviour?

  • JList with JScrollPane and prototype cell value wraps element names (replaces with dots instead of s

    - by Tom
    I've got a Jlist inside a JScrollPane and I've set a prototype value so that it doesn't have to calculate the width for big lists, but just uses this default width. Now, the problem is that the Jlist is for some reason replacing the end of an element with dots (...) so that a horizontal scrollbar will never be shown. How do I disable with "wrapping"? So that long elements are not being replaced with dots if they are wider than the Jlist's width? I've reproduced the issue in a small example application. Please run it if you don't understand what I mean: import javax.swing.*; import java.awt.*; public class Test { //window private static final int windowWidth = 450; private static final int windowHeight = 500; //components private JFrame frame; private JList classesList; private DefaultListModel classesListModel; public Test() { load(); } private void load() { //create window frame = new JFrame("Test"); frame.setSize(windowWidth, windowHeight); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setUndecorated(true); frame.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG); //classes list classesListModel = new DefaultListModel(); classesList = new JList(classesListModel); classesList.setPrototypeCellValue("prototype value"); classesList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); classesList.setVisibleRowCount(20); JScrollPane scrollClasses = new JScrollPane(classesList, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED); for (int i = 0; i < 200; i++) { classesListModel.addElement("this is a long string, does not fit in width"); } //panel JPanel drawingArea = new JPanel(); drawingArea.setBackground(Color.white); drawingArea.add(scrollClasses); frame.add(drawingArea); //set visible frame.setVisible(true); } } Even if you force horizontal scrollbar, you still won't be able to scroll because the element is actually not wider than the width because of the dot (...) wrapping. Thanks in advance.
