  • Maximum Uri Length in Silverlight

    - by Kris Erickson
    Does anyone know what the Maximum URL length is in Silverlight (version 4 if it matters)? I know it is 2048 and basically infinite for Firefox (the two environments I have tested in), but Image requests fail for long Uri's. Anyone know the magic number (is it 256 the max filepath length?) It is considerably shorter than the 2048 for IE...

  • Implementing a continuous "revert-buffer" aka Textpad

    - by vedang
    One of my colleagues uses TextPad, and one feature I found really useful is the Auto-Reload. (The feature has been described in this SO quesion: http://stackoverflow.com/questions/1246083/alternative-to-textpads-prompt-to-reload-file). Basically, it keeps reloading the file without any prompt from the user, which is really helpful when monitoring log files that are updated in real-time. Is there something similar available for Emacs? If not, can anyone whip up the required elisp magic?

  • tmpfile and gzip combination problem

    - by Vojtech R.
    I have problem with this code: file = tempfile.TemporaryFile(mode='wrb') file.write(base64.b64decode(data)) file.flush() os.fsync(file) # file.seek(0) f = gzip.GzipFile(mode='rb', fileobj=file) print f.read() I dont know why it doesn't print out anything. If I uncomment file.seek then error occurs: File "/usr/lib/python2.5/gzip.py", line 263, in _read self._read_gzip_header() File "/usr/lib/python2.5/gzip.py", line 162, in _read_gzip_header magic = self.fileobj.read(2) IOError: [Errno 9] Bad file descriptor Just for information this version works fine: x = open("test.gzip", 'wb') x.write(base64.b64decode(data)) x.close() f = gzip.GzipFile('test.gzip', 'rb') print f.read()

  • Loading SQL dump before running Django tests

    - by knutin
    I have a fairly complex Django project which makes it hard/impossible to use fixtures for loading data. What I would like to do is to load a database dump from the production database server after all tables has bene created by the testrunner and before the actual tests start running. I've tried various "magic" in MyTestCase.setUp(), but with no luck. Any suggestions would be most welcome. Thanks.

  • Managing Java dependencies in a Grails application?

    - by Stefan Kendall
    I'm trying to adopt my development from Spring/Maven2/Tomcat -> Grails, and I'm wondering if there's an easy way to manage dependencies in grails separate from maven. Maven does a lot of the magic that grails is doing automatically (unit testing/building/etc.), so I wonder if there's a need for maven at all in grails projects. So, then, how do Grails users generally manage java dependencies? I've become accustomed to central repository dependency management, and I can't turn back at this point.

  • Help getting started with MEF

    - by SteveCl
    Hi, I was reading somewhere that with MEF I can simply drop a dll into a directory and my application (with some MEF magic) will be able to read it and execute the code in it? Hopefully only classes that implement an interface that I define?? Can someone help me to get going, with some links maybe for my problem. I've looked through some of the docs, but nothing seems to be what I'm after and its tricky when I don't know exactly what to search on... Thx S

  • Is there a boolean literal in SQLite?

    - by Benjamin Oakes
    I know about the boolean column type, but is there a boolean literal in SQLite? In other languages, this might be true or false. Obviously, I can use 0 and 1, but I tend to avoid so-called "magic numbers" where possible. From this list, it seems like it might exist in other SQL implementations, but not SQLite. (I'm using SQLite 3.6.10, for what it's worth.)

  • Any good source of explanatory documentation on ColorMatrix?

    - by mackenir
    I'd like to try using ColorMatrix, but am only able to find examples that convert an image to grayscale. And even then, they tend to be presented as a chunk of 'magic numbers' code with no explanation. Does anyone know of a 'tutorial' on how to use ColorMatrix? For example I'd be interested in converting a grayscale image to a color image, where white == transparent, and black = a solid color, with gray pixels somewhere in between. Could ColorMatrix do that?

  • How do I tell which element a jquery click occurred on?

    - by Colen
    Hi, I am handling a click on a list item with jquery: $("#some_list li").click(function(event) { // magic happens here } The list items look like: <li><input type='checkbox'>Some text<span class='info'>(?)</span></li> I want to have different behaviours depending on whether the user clicks within the (?), or anywhere else in the list. How can I detect which element the user clicked on?

  • How to check if a file is a DLL?

    - by PierreBdR
    Given a file, I want to check if this is a DLL, or a shared object (Linux) or a dylib (Mac OS X), or something different. My main interest is differentiating executable and DLL on Linux and Mac OS X. For windows, the extension should be enough for my problem. I already checked that the magic number technique doesn't work for Linux as executable and shared objects both have the same number.

  • getting around circular references in Delphi

    - by Tom
    Is there a way of getting around circular unit references in Delphi? Maybe a newer version of delphi or some magic hack or something? My delphi project has 100 000+ lines of code mostly based on singleton classes. I need to refactor this, but that would mean several months of "circular reference" hell :)

  • Where does the tomcat axis file server-config.wsdd come from?

    - by David Sykes
    Part of our system provides a web service through apache tomcat, the service is referenced in the server-config.wsdd file. Unfortunately nobody can remember how it got in there. The apache set up has changed, and I need to update the system for the new configuration. What magic keywords can I google for to help me work out how and why it got into the existing server-config.wsdd, and how it might fit into the new server-config.wsdd

  • Good suggestions for learning OOP PHP

    - by Doug
    I've been trying to learn PHP OOP and have looked at multiple articles, but have yet to find a good resource for learning. I want to learn from the user of setters and getters, $this-, constructors, and so on...! Can anyone please suggest me something? I noticed MOST teachings leave out the explanation of $this-. I want to learn magic methods, decorators, encapsulation, etc... Feel free to suggest something that I haven't explicitly listed.

    I've used this official tutorial to setup my machine so it could detect my Android devices.

I've tried googling for a solution but I've found nothing.

  • How to access static members in a Velocity template?

    - by matt b
    I'm not sure if there is a way to do this in Velocity or not: I have a User POJO which a property named Status, which looks like an enum (but it is not, since I am stuck on Java 1.4), the definition looks something like this: public class User { // default status to User private Status status = Status.USER; public void setStatus(Status status) { this.status = status; } public Status getStatus() { return status; } And Status is a static inner class: public static final class Status { private String statusString; private Status(String statusString) { this.statusString = statusString; } public final static Status USER = new Status("user"); public final static Status ADMIN = new Status("admin"); public final static Status STATUS_X = new Status("blah"); //.equals() and .hashCode() implemented as well } With this pattern, a user status can easily be tested in a conditional such as if(User.Status.ADMIN.equals(user.getStatus())) ... ... without having to reference any constants for the status ID, any magic numbers, etc. However, I can't figure out how to test these conditionals in my Velocity template with VTL. I'd like to just print a simple string based upon the user's status, such as: Welcome <b>${user.name}</b>! <br/> <br/> #if($user.status == com.company.blah.User.Status.USER) You are a regular user #elseif($user.status == com.company.blah.User.Status.ADMIN) You are an administrator #etc... #end But this throws an Exception that looks like org.apache.velocity.exception.ParseErrorException: Encountered "User" at webpages/include/dashboard.inc[line 10, column 21] Was expecting one of: "[" ... From the VTL User Guide, there is no mention of accessing a Java class/static member directly in VTL, it appears that the right hand side (RHS) of a conditional can only be a number literal, string literal, property reference, or method reference. So is there any way that I can access static Java properties/references in a Velocity template? I'm aware that as a workaround, I could embed the status ID or some other identifier as a reference in my controller (this is a web MVC application using Velocity as the View technology), but I strongly do not want to embed any magic numbers or constants in the view layer.

  • golang closure variable scope

    - by waaadim
    I'm reading 'CreateSpace An Introduction to Programming in Go 2012' and on page 86 I found this evil magic func makeEvenGenerator() func() uint { i := uint(0) return func() (ret uint) { ret = i i += 2 return } } // here's how it's called nextEven := makeEvenGenerator() fmt.Println(nextEven()) fmt.Println(nextEven()) fmt.Println(nextEven()) 1) Why is i not resetting ? 2) is nextEven() returning and uint or is Println so smart that it can work with everything ?

  • How to get custom form fields from controller -- a.k.a. how to not use date helpers in form

    - by 99miles
    I created a form with scaffold that includes two datetime fields. I replaced them with a datepicker, and now I'm trying to grab the date from within the controller. Instead of having ruby do all the magic work with the datefields, I instead just have to fields, start_date and stop_date that I want to use, but I can't figure out how to grab them from within my controller. Hints? Thanks!

  • Is there a way to identify which web framework is used in a site?

    - by ragu.pattabi
    Whenever I come across a cute website, I am always curious to know which web framework was used by its developers? Being a novice in web development, a look at the page source doesn't give any clue. Any way(s) to get this information? If possible, may be with a bit of Ruby magic, I can figure out things like: which is the most/least used framework for my favorite sites, audio/video heavy sites, etc.
