  • How can I detect the Android emulator?

    - by Joe Ludwig
    I would like to have my code run slightly differently when running on the emulator than when running on a device. (For example, using 10.0.2.2 instead of a public URL to run against a development server automatically.) What is the best way to detect when an Android application is running in the emulator?

  • Django admin.py missing field error

    - by user782400
    When I include 'caption', I get an error saying EntryAdmin.fieldsets[1][1]['fields']' refers to field 'caption' that is missing from the form In the admin.py; I have imported the classes from joe.models import Entry,Image Is that because my class from models.py is not getting imported properly ? Need help in resolving this issue. Thanks. models.py class Image(models.Model): image = models.ImageField(upload_to='joe') caption = models.CharField(max_length=200) imageSrc = models.URLField(max_length=200) user = models.CharField(max_length=20) class Entry(models.Model): image = models.ForeignKey(Image) mimeType = models.CharField(max_length=20) name = models.CharField(max_length=200) password = models.URLField(max_length=50) admin.py class EntryAdmin(admin.ModelAdmin): fieldsets = [ ('File info', {'fields': ['name','password']}), ('Upload image', {'fields': ['image','caption']})] list_display = ('name', 'mimeType', 'password') admin.site.register(Entry, EntryAdmin) admin.site.register(Image)

  • Is NSPasteboard thread-safe?

    - by Joe
    Is it safe to write data to an NSPasteboard object from a background thread? I can't seem to find a definitive answer anywhere. I think the assumption is that the data will be written to the pasteboard before the drag begins. Background: I have an application that is fetching data from Evernote. When the application first loads, it gets the meta data for each note, but not the note content. The note stubs are then listed in an outline view. When the user starts to drag a note, the notes are passed to the background thread that handles getting the note content from Evernote. Having the main thread block until the data is gotten results in a significant delay and a poor user experience, so I have the [outlineView:writeItems:toPasteboard:] function return YES while the background thread processes the data and invokes the main thread to write the data to the pasteboard object. If the note content gets transferred before the user drops the note somewhere, everything works perfectly. If the user drops the note somewhere before the data has been processed... well, everything blocks forever. Is it safe to just have the background thread write the data to the pasteboard?

  • Django admin causes high load for one model...

    - by Joe
    In my Django admin, when I try to view/edit objects from one particular model class the memory usage and CPU rockets up and I have to restart the server. I can view the list of objects fine, but the problem comes when I click on one of the objects. Other models are fine. Working with the object in code (i.e. creating and displaying) is ok, the problem only arises when I try to view an object with the admin interface. The class isn't even particularly exotic: class Comment(models.Model): user = models.ForeignKey(User) thing = models.ForeignKey(Thing) date = models.DateTimeField(auto_now_add=True) content = models.TextField(blank=True, null=True) approved = models.BooleanField(default=True) class Meta: ordering = ['-date'] Any ideas? I'm stumped. The only reason I could think of might be that the thing is quite a large object (a few kb), but as I understand it, it wouldn't get loaded until it was needed (correct?).

  • regex to match postgresql bytea

    - by filiprem
    In PostgreSQL, there is a BLOB datatype called bytea. It's just an array of bytes. bytea literals are output in the following way: '\\037\\213\\010\\010\\005`Us\\000\\0001.fp3\'\\223\\222%' See PostgreSQL docs for full definition of the format. I'm trying to construct a Perl regular expression which will match any such string. It should also match standard ANSI SQL string literals, like 'Joe', 'Joe''s Mom', 'Fish Called ''Wendy''' It should also match backslash-escaped variant: 'Joe\'s Mom', . First aproach (shown below) works only for some bytea representations. s{ ' # Opening apostrophe (?: # Start group [^\\\'] # Anything but a backslash or an apostrophe | # or \\ . # Backslash and anything | # or \'\' # Double apostrophe )* # End of group ' # Closing apostrophe }{LITERAL_REPLACED}xgo; For other (longer ones, with many escaped apostrophes, Perl gives such warning: Complex regular subexpression recursion limit (32766) exceeded at ./sqa.pl line 33, < line 1. So I am looking for a better (but still regex-based) solution, it probably requires some regex alchemy (avoiding backreferences and all).

  • AOL Contact API and AIM Buddy API

    - by Joe Davis
    I've searched the AOL Developer network and found a Contacts API page that says "coming soon" and is dated last year. I've checked the SDK and APIs and found some AIM Buddy references... I'm looking for documentation on retrieving contact email addresses on behalf of users based on their AOL email login. Am I missing something or is the documentation really difficult to find? Does someone have a useful link?

  • internal ToMVCHmlString in TagBuilder

    - by Joe
    I am looking to write a few helpers in my own assembly modeled after the helpers in System.web.mvc. My problem is that I cannot use the call to Tagbuilder.ToMvcHtlString since it is internal. So if I return a string it wont be ready for asp.net 4 when it comes. I dont want to add anything to system.web.mvc as that is a given dll.

  • How to achieve a palette effect on iPhone using OpenGL

    - by Joe
    I'm porting a 2d retro game to iPhone that has the following properties: targets OpenGL ES 1.1 entire screen is filled with tiles (textured triangle strip tile textured using a single 256x256 RGBA texture image the texture is passed to OpenGL once at the start of the game only 4 displayed colours are used one of the displayed colours is black The original game flashed the screen when time starts to run out by toggling the black pixels to white using an indexed palette. What is the best (i.e. most efficient) way to achieve this in OpenGL ES 1.1? My thoughts so far: Generate an alternative texture with white instead of black pixels, and pass to OpenGL when the screen is flashing Render a white poly underneath the background and render the texture with alpha on to display it Try and render a poly on top with some blending that achieves the effect (not sure this is possible) I'm fairly new to OpenGL so I'm not sure what the performance drawbacks of each of these are, or if there's a better way of doing this.

  • How to add my program to the OS X system menu bar?

    - by Joe
    I have created a volume controller for iTunes but I would like this app to place an icon on the OS X system menu bar and have my slider controller drop down. I created this because I have to switch to iTunes to change the volume of the music because I am using the digital-out audio and the keyboard keys do not work in digital-out mode. Any guidance would be greatly appreciated.

  • How do I set the current point in a CG graphics context?

    - by Joe
    When running the code below in the iphone simulator I get the error : CGContextClosePath: no current point. Why is the current point not being set? Or is the context not set to the correct state? CGContextBeginPath(ctx); CGMutablePathRef pathHolder; pathHolder = CGPathCreateMutable(); //move to point for the initial point NSLog(@"Drawing a state point %f, %f", [[holder.points objectAtIndex:0] floatValue], [[holder.points objectAtIndex:1] floatValue]); CGPathMoveToPoint(pathHolder, NULL, [[holder.points objectAtIndex:0] floatValue], [[holder.points objectAtIndex:1] floatValue]); for(int x = 2; x < [holder.points count] - 1; x += 2) { NSLog(@"Drawing a state point %f, %f", [[holder.points objectAtIndex:x] floatValue], [[holder.points objectAtIndex:(x+1)] floatValue]); CGPathAddLineToPoint(pathHolder, NULL, [[holder.points objectAtIndex:x] floatValue], [[holder.points objectAtIndex:(x+1)] floatValue]); } CGContextClosePath(ctx); CGContextFillPath(ctx);

  • Webdav -- GET on a directory

    - by Joe Cannatti
    I am beginning to build a tool that uses WebDAV. I am having trouble wrapping my head around something here. I think I am missing something conceptual. I can use PUT's to add files to the server. I can use GET's to read files from the server, but when I try to use GET on a directory I get a 403:Forbidden. I am using basic authentication. My code in MacRuby is as follows Net::HTTP.start('localhost') do |http| res = Net::HTTP::Get.new('http://localhost/webdav/') res.basic_auth 'jcannatti', 'webdav' http.request res end this returns <Net::HTTPForbidden 403 Forbidden readbody=true> however this Net::HTTP.start('localhost') do |http| res = Net::HTTP::Put.new('http://localhost/webdav/gorilla.txt') res.body = "testetsetest" res.basic_auth 'jcannatti', 'webdav' http.request res end returns <Net::HTTPCreated 201 Created readbody=true> What should happen when calling a GET on a WebDAV directory when everything is working correctly? thanks

  • Iterating Over Params Hash

    - by Joe Clark
    I'm having an extremely frustrating time getting some images to upload. They are obviously being uploaded as rack/multipart but the way that I'm iterating over my params hash must be causing the problem. I could REALLY use some help, so I can stop pulling out my hair. So I've got a params hash that looks like this: Parameters: {"commit"=>"Submit", "sighting_report"=>[{"number_seen"=>"1", "picture"=>#<File:/var/folders/IX/IXXrbzpCHkq68OuyY-yoI++++TI/-Tmp-/RackMultipart.85991.5>, "species_id"=>"2"}], "authenticity_token"=>"u0eN5MAfvGWtfEzrqBt4qfrL54VJ9SGX0jFLZCJ8iRM=", "sighting"=>{"sighting_date(2i)"=>"6", "name"=>"", "sighting_date(3i)"=>"5", "county"=>"0", "notes"=>"", "location"=>"", "sighting_date(1i)"=>"2010", "email"=>""}} My form can have multiple sighting reports with multiple pictures in each sighting report. Here's my controller code: def create_multiple @report = Report.new @report.name = params[:sighting]["name"] @report.sighting_date = Date.civil(params[:sighting][:"sighting_date(1i)"].to_i, params[:sighting][:"sighting_date(2i)"].to_i, params[:sighting][:"sighting_date(3i)"].to_i) @report.county_id = params[:sighting][:county] @report.location = params[:sighting][:location] @report.notes = params[:sighting][:notes] @report.email = params[:sighting][:email] @report.save! @report.reload for sr in params[:sighting_report] do sighting = SightingReport.new sighting.report_id = @report.id sighting.species_id = sr[:species_id] sighting.number_seen = sr[:number_seen] sighting.save if sr[:picture] sighting.reload for pic in sr[:picture] do p = SpeciesPic.new p.uploaded_picture = pic p.species_id = sighting.species_id p.report_id = @report.id p.save! end end end redirect_to :action => 'new_multiple' end

  • C++ Ambiguous call to Overloaded Function (const variety)

    - by Joe
    After researching this online, I've only found solutions that don't apply to my problem, so please bear with me. Code snippet: typedef my_map_t<int const *, float> _test; my_map_t::const_iterator not_found = my_map_t::end(); if (_test.find(&iKeyValue) == not_found) { _test[iKeyValue] = 4 + 5; // not the actual code, but here for simplicity } The compiler complains that there's an ambiguous call to my_map_t::end(). This makes sense, because the only difference is the return type. Output: error C2668: 'std::_Tree<_Traits>::end' : ambiguous call to overloaded function Normally you can disambiguate the call by casting the parameters, but end() has no parameters. Any ideas?

  • Managing string resources in a Java application - singleton?

    - by Joe Attardi
    I seek a solution to the age-old problem of managing string resources. My current implementation seems to work well, but it depends on using singletons, and I know how often singletons can be maligned. The resource manager class has a singleton instance that handles lookups in the ResourceBundle, and you use it like so: MessageResources mr = MessageResources.getMessageResources(); // returns singleton instance ... JLabel helloLabel = new JLabel(mr.getString("label.hello")); Is this an appropriate use of a singleton? Is there some better, more universally used approach that I'm not aware of? I understand that this is probably a bit subjective, but any feedback I can get would be appreciated. I'd rather find out early on that I'm doing it wrong than later on in the process. Thanks!

  • Insert Comment Reply Form Into Page Using Jquery

    - by Joe
    I have been making a threaded comment system as a way to learn php and javascript/jquery properly. Ive done bits and bobs in the past but ive made a new years resolution to learn it properly. Im having trouble inserting a reply form into the comment tree below the comment being replied to. I know this is probably pretty basic but how do you insert html into a page when someone clicks a link. This code wasn't working for me: $(document).ready(function(){ $(function() { $('a#reply').click(function() { $(this).append("the html blah"); }); }); }); Anyone see where im going wrong?

  • [PHP] access array element by value

    - by Brandon
    array( [0] name => 'joe' size => 'large' [1] name => 'bill' size => 'small' ) I think i'm being thick, but to get the attributes of an array element if I know the value of one of the keys, I'm first looping through the elements to find the right one. foreach($array as $item){ if ($item['name'] == 'joe'){ #operations on $item } } I'm aware that this is probably very poor, but I am fairly new and am looking for a way to access this element directly by value. Or do I need the key? Thanks, Brandon

  • Memory leak - debugger and memory analyzer disagreeing

    - by Joe
    There is a memory leak in my android game - I've managed to narrow it down to a certain object, which has a list of objects to render on a texture. This object clears the list every time it draws though - so I can't work out how its managed to get thousands of elements in the list. I checked in the debugger and it doesn't have all these thousands of elements - usually about 2-20 which is what I'd expect... The game definitely slows down progressively only if I have rendering to texturing on. Here is a picture of Memory Analyzer showing 6,111 items: Memory Analyzer Here is a picture of the debugger showing 2: Debugger Can anyone help me find out whats wrong?

  • How do I use a shared library (in this case JsonCpp) in my C++ program on Linux?

    - by Not Joe Bloggs
    I'm a new-ish C++ programmer, and I'm doing my first program on my own using C++. I decided I would like to use JSON to store some of the data I'm going to be using, and I've found a library to handle JSON, JsonCpp. I've installed the library using my Linux system's package manager, and in my C++ code, I've used in my source code file #include <json> and compiled it using g++ and it's -ljson and -L/usr/lib options (libjson.so is located in /usr/lib). However, the first usage of Json::Value, an object provided by the library, gives a compilation error of "Json has not declared". I'm sure my mistake is something simple, so could someone explain what I'm doing wrong? None of the books I had mention how to use shared libraries, so I've had to google to find this much.

  • Modify EXE to stop launching firefox

    - by Random Joe
    I'm using a wireless modem program from my ISP. This program automatically disconnect when it detects the line is idle. It does so in 2-5 minutes of idle time. Whenever I reconnect, It will automatically fire up my default browser to the ISP portal. I DID NOT pay them to shove their web portal in my face 50 times a day. The ISP provides no options for disabling this behavior. Can someone please show me how to hex edit the EXE program to stop it from annoying the hell out of me?

  • Query Concatenated Field (using SubSonic)

    - by jwynveen
    Is there a way to query against a concatenated field using MS SQL? For instance, what I want to do is something like: Select FirstName+' '+LastName as FullName from Attendees where FullName like '%Joe Schmoe%' The above doesn't work. What I have found works is: Select * from Attendee where FirstName+' '+LastName like '%Joe Schmoe%' but I can't figure out how to do that using a SubSonic SqlQuery. I have a number of joins and OR statements added dynamically that I don't want to have to write out the sql manually. Any help/ideas?

  • Convert Form to UserControl

    - by Joe
    I have a 3rd party code library that I'm using; part of this library is a winforms application for editing the configuration files used by this library. I would like to embed their configuration editor app into my application. I have the source code to their library and the configuration editor is (as far as I can tell) a straight forward Winforms app using standard controls. I'm trying to convert the app's main form into a UserControl so that I can host it inside my application which is WPF (WPF's WindowsFormsHost won't host a Form object, I get an exception). I changed the form object to inherit from UserControl instead of Form and fixed all the compiler errors (there weren't many, just property initializations that don't exist on UserControls) but what's happening is my newly converted control is just blank. When I run my test app I don't see any of the controls that make up the original form, just a blank page. Any ideas? I really don't want to have to re-implement their app from scratch, that would suck. Edit: I forgot to mention I'm testing this in a WinForms application, not WPF, to just get the control working before trying to use it from WPF.

  • Is it too early to start designing for Task Parallel Library?

    - by Joe Erickson
    I have been following the development of the .NET Task Parallel Library (TPL) with great interest since Microsoft first announced it. There is no doubt in my mind that we will eventually take advantage of TPL. What I am questioning is whether it makes sense to start taking advantage of TPL when Visual Studio 2010 and .NET 4.0 are released, or whether it makes sense to wait a while longer. Why Start Now? The .NET 4.0 Task Parallel Library appears to be well designed and some relatively simple tests demonstrate that it works well on today's multi-core CPUs. I have been very interested in the potential advantages of using multiple lightweight threads to speed up our software since buying my first quad processor Dell Poweredge 6400 about seven years ago. Experiments at that time indicated that it was not worth the effort, which I attributed largely to the overhead of moving data between each CPU's cache (there was no shared cache back then) and RAM. Competitive advantage - some of our customers can never get enough performance and there is no doubt that we can build a faster product using TPL today. It sounds fun. Yes, I realize that some developers would rather poke themselves in the eye with a sharp stick, but we really enjoy maximizing performance. Why Wait? Are today's Intel Nehalem CPUs representative of where we are going as multi-core support matures? You can purchase a Nehalem CPU with 4 cores which share a single level 3 cache today, and most likely a 6 core CPU sharing a single level 3 cache by the time Visual Studio 2010 / .NET 4.0 are released. Obviously, the number of cores will go up over time, but what about the architecture? As the number of cores goes up, will they still share a cache? One issue with Nehalem is the fact that, even though there is a very fast interconnect between the cores, they have non-uniform memory access (NUMA) which can lead to lower performance and less predictable results. Will future multi-core architectures be able to do away with NUMA? Similarly, will the .NET Task Parallel Library change as it matures, requiring modifications to code to fully take advantage of it? Limitations Our core engine is 100% C# and has to run without full trust, so we are limited to using .NET APIs.
