  • 3D Texture mapping

    - by Joe Cannatti
    In an .obj, file it is possible to specify 3 values for a vt line. vt 0.769645 0.729072 0.00000000 The .obj spec says its for "depth". What does this actually do and when is it useful?

  • Why did the upgrade from 11.10 to 12.04 ruin my system?

    - by Jared
    After upgrading from Ubuntu 11.10 to 12.04, when I log in, everything is ruined. It's all black, blank white icons, blank black icons on the start menu, and well, nothing works. If I open up Chromium, it looks as though it's in high contrast mode. Is this a bug? Any ideas what could have happened? Can I get 11.10 back? Some photos (can't connect to network in Ubuntu so I had to take pictures with phone): http://i.stack.imgur.com/2dwKl.jpg http://i.stack.imgur.com/N4nA3.jpg http://i.stack.imgur.com/LNFje.jpg

  • Getting Argument Names In Ruby Reflection

    - by Joe Soul-bringer
    I would like to do some fairly heavy-duty reflection in the Ruby programming language. I would like to create a function which would return the names of the arguments of various calling functions higher up the call stack (just one higher would be enough but why stop there?). I could use Kernel.caller go to the file and parse the argument list but that would be ugly and unreliable. The function that I would like would work in the following way: module A def method1( tuti, fruity) foo end def method2(bim, bam, boom) foo end def foo print caller_args[1].join(",") #the "1" mean one step up the call stack end end A.method1 #prints "tuti,fruity" A.method2 #prints "bim, bam, boom" I would not mind using ParseTree or some similar tool for this task but looking at Parsetree, it is not obvious how to use it for this purpose. Creating a C extension like this is another possibility but it would be nice if someone had already done it for me. Edit2: I can see that I'll probably need some kind of C extension. I suppose that means my question is what combination of C extension would work most easily. I don't think caller+ParseTree would be enough by themselves. As far as why I would like to do this goes, rather than saying "automatic debugging", perhaps I should say that I would like to use this functionality to do automatic checking of the calling and return conditions of functions. Say def add x, y check_positive return x + y end Where check_positive would throw an exception if x and y weren't positive (obviously, there would be more to it than that but hopefully this gives enough motivation)

  • USB3 boot device disappears post-grub

    - by JoBu1324
    I have an installation of Ubuntu 12.10 on a USB3 device, and it occasionally disappears during boot, dropping me into busybox. This is what I've been able to figure out so far: During a single boot, the following happened: At the grub2 menu, I typed c and dropped to the grub> prompt I typed ls -l and got a list of all the devices, including partitions and UUIDs - the USB3 partitions were available I escaped back to the boot select menu, selected the default item (ubuntu) and hit enter The screen went black for a second before turning into the purple Ubuntu boot screen with the dots (which usually indicates that the boot will fail. When all is well I don't get the black screen) The boot dropped into BusyBox v1.19.3 with the message `ALERT! /dev/disk/by-uuid/[uuid] does not exist blkid displays all of the partitions except those of the USB3 device, as does ls /dev/disk/by-uuid or any of the alternatives.

    Possible Duplicate: My computer boots to a black screen, what options do I have to fix it? i tried to install Ubuntu 12.04 64Bit, 12.10 32 and 64Bit, but it doesn't work.

  • 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

    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 ?

  • 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?).

  • 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?

  • Multiple problems while installing Ubuntu 13.04 on LENOVO G500 laptop

    - by Balazs Kiss
    Dear Community, I encountered several problems when installing Ubuntu on my new Lenovo G500 laptop. First I bumped in the problem (also reported by many other) of the black screen after booting Ubuntu. This problem I recould solve by changing the "quiet splash" record of GRUB to "nomodeset". Ubuntu install was successful then. After the installation, I had a black screen again when booting up for the first time. I booted up again with "nomodeset", and enabled the external AMD driver at Hardware Drivers. Booting still do not worked (only with nomodeset), and when I log in, the system gives me a "System program problem detected" message, and the system (desktop) does not load in. Please, can you advise me what to do? Shall I re-install Ubuntu? What are the steps to make my ubuntu work with this harver? Hardware: LENOVO G500 with IntelCore i5-3230M 3,2Ghz processor and AMD Radeon HD8570 integrated chip Thank you for your help in advance!

  • 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).

    - 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.

  • 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

  • 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

  • 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?

  • Problem implementing Blinn–Phong shading model

    - by Joe Hopfgartner
    I did this very simple, perfectly working, implementation of Phong Relflection Model (There is no ambience implemented yet, but that doesn't bother me for now). The functions should be self explaining. /** * Implements the classic Phong illumination Model using a reflected light * vector. */ public class PhongIllumination implements IlluminationModel { @RGBParam(r = 0, g = 0, b = 0) public Vec3 ambient; @RGBParam(r = 1, g = 1, b = 1) public Vec3 diffuse; @RGBParam(r = 1, g = 1, b = 1) public Vec3 specular; @FloatParam(value = 20, min = 1, max = 200.0f) public float shininess; /* * Calculate the intensity of light reflected to the viewer . * * @param P = The surface position expressed in world coordinates. * * @param V = Normalized viewing vector from surface to eye in world * coordinates. * * @param N = Normalized normal vector at surface point in world * coordinates. * * @param surfaceColor = surfaceColor Color of the surface at the current * position. * * @param lights = The active light sources in the scene. * * @return Reflected light intensity I. */ public Vec3 shade(Vec3 P, Vec3 V, Vec3 N, Vec3 surfaceColor, Light lights[]) { Vec3 surfaceColordiffused = Vec3.mul(surfaceColor, diffuse); Vec3 totalintensity = new Vec3(0, 0, 0); for (int i = 0; i < lights.length; i++) { Vec3 L = lights[i].calcDirection(P); N = N.normalize(); V = V.normalize(); Vec3 R = Vec3.reflect(L, N); // reflection vector float diffuseLight = Vec3.dot(N, L); float specularLight = Vec3.dot(V, R); if (diffuseLight > 0) { totalintensity = Vec3.add(Vec3.mul(Vec3.mul( surfaceColordiffused, lights[i].calcIntensity(P)), diffuseLight), totalintensity); if (specularLight > 0) { Vec3 Il = lights[i].calcIntensity(P); Vec3 Ilincident = Vec3.mul(Il, Math.max(0.0f, Vec3 .dot(N, L))); Vec3 intensity = Vec3.mul(Vec3.mul(specular, Ilincident), (float) Math.pow(specularLight, shininess)); totalintensity = Vec3.add(totalintensity, intensity); } } } return totalintensity; } } Now i need to adapt it to become a Blinn-Phong illumination model I used the formulas from hearn and baker, followed pseudocodes and tried to implement it multiple times according to wikipedia articles in several languages but it never worked. I just get no specular reflections or they are so weak and/or are at the wrong place and/or have the wrong color. From the numerous wrong implementations I post some little code that already seems to be wrong. So I calculate my Half Way vector and my new specular light like so: Vec3 H = Vec3.mul(Vec3.add(L.normalize(), V), Vec3.add(L.normalize(), V).length()); float specularLight = Vec3.dot(H, N); With theese little changes it should already work (maby not with correct intensity but basically it should be correct). But the result is wrong. Here are two images. Left how it should render correctly and right how it renders. If i lower the shininess factor you can see a little specular light at the top right: Altough I understand the concept of Phong illumination and also the simplified more performant adaptaion of blinn phong I am trying around for days and just cant get it to work. Any help is appriciated. Edit: I was made aware of an error by this answer, that i am mutiplying by |L+V| instead of dividing by it when calculating H. I changed to deviding doing so: Vec3 H = Vec3.mul(Vec3.add(L.normalize(), V), 1/Vec3.add(L.normalize(), V).length()); Unfortunately this doesnt change much. The results look like this: and if I rise the specular constant and lower the shininess You can see the effects more clearly in a smilar wrong way: However this division just the normalisation. I think I am missing one step. Because the formulas like this just dont make sense to me. If you look at this picture: http://en.wikipedia.org/wiki/File:Blinn-Phong_vectors.svg The projection of H to N is far less than V to R. And if you imagine changing the vector V in the picture the angle is the same when the viewing vector is "on the left side". and becomes more and more different when going to the right. I pesonally would multiply the whole projection by two to become something similiar (and the hole point is to avoid the calculation of R). Altough I didnt read anythinga bout that anywehre i am gonna try this out... Result: The intension of the specular light is far too much (white areas) and the position is still wrong. I think I am messing something else up because teh reflection are just at the wrong place. But what? Edit: Now I read on wikipedia in the notes that the angle of N/H is in fact approximalty half or V/R. To compensate that i should multiply my shineness exponent by 4 rather than my projection. If i do that I end up with this: Far to intense but still one thing. The projection is at the wrong place. Where could i mess up my vectors?

  • 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?
