  • How to programatically set drawableLeft on Android button?

    - by Frank LoVecchio
    I'm dynamically creating buttons. I styled them using XML first, and I'm trying to take the XML below and make it programattic. <Button android:id="@+id/buttonIdDoesntMatter" android:layout_height="wrap_content" android:layout_width="fill_parent" android:text="buttonName" android:drawableLeft="@drawable/imageWillChange" android:onClick="listener" android:layout_width="fill_parent"> </Button> This is what I have so far. I can do everything but the drawable. linear = (LinearLayout) findViewById(R.id.LinearView); Button button = new Button(this); button.setText("Button"); button.setOnClickListener(listener); button.setLayoutParams( new LayoutParams( android.view.ViewGroup.LayoutParams.FILL_PARENT, android.view.ViewGroup.LayoutParams.WRAP_CONTENT ) ); linear.addView(button);

  • Using CSS gradient instead of images

    - by Wiika
    Using CSS for creating gradients instead of images, does it have any negativity? For example the following code: #gradient { color: #fff; height: 100px; padding: 10px; /* For WebKit (Safari, Google Chrome etc) */ background: -webkit-gradient(linear, left top, left bottom, from(#00f), to(#fff)); /* For Mozilla/Gecko (Firefox etc) */ background: -moz-linear-gradient(top, #00f, #fff); /* For Internet Explorer 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#FF0000FF, endColorstr=#FFFFFFFF); /* For Internet Explorer 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#FF0000FF, endColorstr=#FFFFFFFF)"; } Thanks.

  • How do I make matlab legends match the colour of the graphs?

    - by Alex Gosselin
    Here is the code I used: x = linspace(0,2); e = exp(1); lin = e; quad = e-e.*x.*x/2; cub = e-e.*x.*x/2; quart = e-e.*x.*x/2+e.*x.*x.*x.*x/24; act = e.^cos(x); mplot = plot(x,act,x,lin,x,quad,x,cub,x,quart); legend('actual','linear','quadratic','cubic','quartic') This produces a legend matching the right colors to actual and linear, then after that it seems to skip over red on the graph, but not on the legend, i.e. the legend says quadratic should be red, but the graph shows it as green, the legend says cubic should be green, but the graph shows it as purple etc. Any help is appreciated.

  • JSON, Ajax login and signup form problem, critique

    - by user552828
    Here is my problem; indexdeneme2.php has two forms Sign up and Login form, and there is validation.js and login.js which are handling the AJAX and JSON response, there are validate.php and login.php which are my scripts for validating and login. When you sign up, it sends the data to validate.php perfectly and validate.php response with JSON perfectly, validate.js must show the error in #error div. validation.js works perfectly if it is working alone. I use same kind of script for login form. Login.php also works perfectly it responses with JSON and login.js shows the errors are appear in #errorlogin div. But this works when login.js works alone. When I try to work login.js and validate.js together, it is not working. validate.php and login.php works perfectly but login.js and validation.js are not working together. They can't handle the responses coming from php scripts. It is not showing the errors in #errorlogin and #error div. They intercept each other I guess. By the way if you can critique my login.php and validate.php I will be really appreciated. Thank you all. this is indexdeneme2.php <?php include('functions.php')?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html;

  • Neural Network problems

    - by Betamoo
    I am using an external library for Artificial Neural Networks in my project.. While testing the ANN, It gave me output of all NaN (not a number in C#) The ANN has 8 input , 5 hidden , 5 hidden , 2 output, and all activation layers are of Linear type , and it uses back-propagation, with learning rate 0.65 I used one testcase for training { -2.2, 1.3, 0.4, 0.5, 0.1, 5, 3, -5 } ,{ -0.3, 0.2 } for 1000 epoch And I tested it on { 0.2, -0.2, 5.3, 0.4, 0.5, 0, 35, 0.0 } which gave { NaN , NaN} Note: this is one example of many that produces same case... I am trying to discover whether it is a bug in the library, or an illogical configuration.. The reasons I could think of for illogical configuration: All layers should not be linear Can not have descending size layers, i.e 8-5-5-2 is bad.. Only one testcase ? Values must be in range [0,1] or [-1,1] Is any of the above reasons could be the cause of error, or there are some constraints/rules that I do not know in ANN designing..? Note: I am newbie in ANN

  • HLSL tex2d sampler seemingly returning incorrect values; why?

    - by BlueNovember
    Hello all, I have code that needs to render regions of my object differently depending on their location. I am trying to use a colour map to define these regions, then get a value (0-14) representing this region by sampling the texture. The problem is when I sample from my colour map, I get collisions. Ie, two regions with different colours in the colourmap get the same value returned from the sampler. I've tried various formats of my colour map. I set the colours for each region to be "5" apart in each case; Indexed colour RGB, RGBA: region 1 will have RGB 5,5,5. region 2 will have RGB 10,10,10 and so on. HSV Greyscale: region 1 will have HSV 0,0,5. region 2 will have HSV 0,0,10 and so on. The tex2D sampler returns a value [0..1]. To get the "region number" I multiply this by 100 and divide by 5, expecting a number [0..20]. (But currently only using 0-14) I am using Shader Model 2 and FX Composer. //Colour map texture gColourmapTexture < string ResourceName = "Globe_Colourmap_Regions_Greyscale.png"; string ResourceType = "2D"; >; sampler2D gColourmapSampler : register(s1) = sampler_state { Texture = <gColourmapTexture>; #if DIRECT3D_VERSION >= 0xa00 Filter = MIN_MAG_MIP_LINEAR; #else /* DIRECT3D_VERSION < 0xa00 */ MinFilter = Linear; MipFilter = Linear; MagFilter = Linear; #endif /* DIRECT3D_VERSION */ AddressU = Clamp; AddressV = Clamp; }; ... //Then later, in a method float region = tex2D(gColourmapSampler,In.UV).x; //at this point I do not think it matters which of xyz components I pick; even in HSV they're all the same for my image. region *= 100; //Now in range [0..100] region /= 5; //Now in range [0..20] float3 levels[21]; //*Code populating "levels" array with what is essentially colour information * levels[1] = ... levels[2] = ... //Chose which level this region has, by looking up its region number float3 Level = levels[region];

  • Calculation route length

    - by Paul Peelen
    Hi, I have a map with about 80 annotations. I would like to do 3 things. 1) From my current location, I would like to know the actual route distance to that position. Not the linear distance. 2) I want to be able to show a list of all the annotations, but for every annotation (having lon/lat) I would like to know the actual route distance from my position to that position. 3) I would like to know the closest annotation to my possition using route distance. Not linear distance. I think the answer to all these three points will be the same. But please keep in mind that I don't want to create a route, I just want to know the distance to the annotation. I hope someone can help me. Best regards, Paul Peelen

  • Running log operation in Http Modules?

    - by Niranjan
    Hi, I have a simple requirement in which I want to execute a long running application program on server (e.g. DTSX) I want to make an HTTP module for this, But I have a question whether the DTSX will run even if the user closes the page and browser. In my case user hits the handler with a query string but what if the user closes the browser immediately? How is the behavior different from simple linear page processing? I want my DTSX package to finish once its started no matter how much time it takes and also dont want to halt the user that is why I am using http modules in place of linear asp page processing. Reagrds, Niranjan

  • Eta/Eta-squared routines in R

    - by aL3xa
    Apart from graphical estimation of linearity (gaze-at-scatterplot method), which is utilized before applying some technique from GLM family, there are several ways to do this estimation arithmetically (i.e. without graphs). Right now, I'll focus on Fisher's eta-squared - correlation ratio: arithmetically, it's equal to squared Pearson's r (coef. of determination: R2) if relationship between two variables is linear. Hence, you can compare values of eta and r and make an assessment about type of relation (linear or not). It provides an information about percent of variance in the dependent variable explained (linearly or not) by the independent variable. Therefore, you can apply it when linearity assumptions are not met. Simply stated: is there a routine for eta/eta-squared in R?

  • analysis Big Oh notation psuedocode

    - by tesshu
    I'm having trouble getting my head around algorithm analysis. I seem to be okay identifying linear or squared algorithms but am totally lost with nlogn or logn algorithms, these seem to stem mainly from while loops? Heres an example I was looking at: Algorithm Calculate(A,n) Input: Array A of size n t?0 for i?0 to n-1 do if A[i] is an odd number then Q.enqueue(A[i]) else while Q is not empty do t?t+Q.dequeue() while Q is not empty do t?t+Q.dequeue() return t My best guess is the for loop is executed n times, its nested while loop q times making NQ and the final while loop also Q times resulting in O(NQ +Q) which is linear? I am probably totally wrong. Any help would be much appreciated. thanks

  • Pruning data for better viewing on loglog graph - Matlab

    - by Geodesic
    Hi Guys, just wondering if anyone has any ideas about an issue I'm having. I have a fair amount of data that needs to be displayed on one graph. Two theoretical lines that are bold and solid are displayed on top, then 10 experimental data sets that converge to these lines are graphed, each using a different identifier (eg the + or o or a square etc). These graphs are on a log scale that goes up to 1e6. The first few decades of the graph (< 1e3) look fine, but as all the datasets converge ( 1e3) it's really difficult to see what data is what. There's over 1000 data points points per decade which I can prune linearly to an extent, but if I do this too much the lower end of the graph will suffer in resolution. What I'd like to do is prune logarithmically, strongest at the high end, working back to 0. My question is: how can I get a logarithmically scaled index vector rather than a linear one? My initial assumption was that as my data is lenear I could just use a linear index to prune, which lead to something like this (but for all decades): //%grab indicies per decade ind12 = find(y >= 1e1 & y <= 1e2); indlow = find(y < 1e2); indhigh = find(y > 1e4); ind23 = find(y >+ 1e2 & y <= 1e3); ind34 = find(y >+ 1e3 & y <= 1e4); //%We want ind12 indexes in this decade, find spacing tot23 = round(length(ind23)/length(ind12)); tot34 = round(length(ind34)/length(ind12)); //%grab ones to keep ind23keep = ind23(1):tot23:ind23(end); ind34keep = ind34(1):tot34:ind34(end); indnew = [indlow' ind23keep ind34keep indhigh']; loglog(x(indnew), y(indnew)); But this causes the prune to behave in a jumpy fashion obviously. Each decade has the number of points that I'd like, but as it's a linear distribution, the points tend to be clumped at the high end of the decade on the log scale. Any ideas on how I can do this?

  • HLSL tex2d sampler seemingly using inconsistent rounding; why?

    - by RJFalconer
    Hello all, I have code that needs to render regions of my object differently depending on their location. I am trying to use a colour map to define these regions. The problem is when I sample from my colour map, I get collisions. Ie, two regions with different colours in the colourmap get the same value returned from the sampler. I've tried various formats of my colour map. I set the colours for each region to be "5" apart in each case; Indexed colour RGB, RGBA: region 1 will have RGB 5%,5%,5%. region 2 will have RGB 10%,10%,10% and so on. HSV Greyscale: region 1 will have HSV 0,0,5%. region 2 will have HSV 0,0,10% and so on. (Values selected in The Gimp) The tex2D sampler returns a value [0..1]. [ I then intend to derive an int array index from region. Code to do with that is unrelated, so has been removed from the question ] float region = tex2D(gColourmapSampler,In.UV).x; Sampling the "5%" colour gave a "region" of 0.05098 in hlsl. From this I assume the 5% represents 5/100*255, or 12.75, which is rounded to 13 when stored in the texture OR when sampled by the sampler; can't tell which. (Reasoning: 0.05098 * 255 ~= 13) By this logic, the 50% should be stored as 127.5. Sampled, I get 0.50196 which implies it was stored as 128. the 70% should be stored as 178.5. Sampled, I get 0.698039, which implies it was stored as 178. What rounding is going on here? (127.5 becomes 128, 178.5 becomes 178 ?!) Edit: OK, http://en.wikipedia.org/wiki/Bankers_rounding#Round_half_to_even Apparently this is "banker's rounding". Is this really what HLSL samplers use? I am using Shader Model 2 and FX Composer. This is my sampler declaration; //Colour map texture gColourmapTexture < string ResourceName = "Globe_Colourmap_Regions_Greyscale.png"; string ResourceType = "2D"; >; sampler2D gColourmapSampler : register(s1) = sampler_state { Texture = <gColourmapTexture>; #if DIRECT3D_VERSION >= 0xa00 Filter = MIN_MAG_MIP_LINEAR; #else /* DIRECT3D_VERSION < 0xa00 */ MinFilter = Linear; MipFilter = Linear; MagFilter = Linear; #endif /* DIRECT3D_VERSION */ AddressU = Clamp; AddressV = Clamp; };

  • How to get orientation of android from gyrsocope sensor events ?

    - by Pritam
    I am using android 2.3 on Nexus S and want to get orientation from gyroscope sensor events. As gyro gives angular velocity how to use this for getting device orientation ? Also is there any way we can get pure linear accelerations on phone's axis, without gravity vector. I expected this from Linear acceleration sensor event but just found a post and referred android source as well for Sensor which currently uses only accelerometer. So what's the best way to combine the readings from both hardware to get pure accelerations without gravity inclusions ? Thanks.

  • How can I call some javascript functions but, waiting for the previous has finished?

    - by texai
    I want to call some functions but waiting for the previous one has finished. I know jQuery provides a callback argument in several functions, but I want to learn how implement this behaviour in my own jQuery plugin. So this is the case: After read answers from my previous question I wrote this: (function(callback){ $('#art1').animate({'width':'1000px'},1000); callback(); })((function(callback2){ $('#art2').animate({'width':'1000px'},1000); callback2(); })(function(){ $('#art3').animate({'width':'1000px'},1000); })); But still not working. Three animates still starting at same time. I want they were called one after other. But without using: $('#art1').animate({'width':'1000px'},1000,'linear',function(){ $('#art2').animate({'width':'1000px'},1000,'linear',function(){ $('#art3').animate({'width':'1000px'},1000); }); });

  • Animate function jQuery

    - by Antonio Pitasi
    I'm new here and I have a problem the jQuery's function "animate" function myFunction(newpage) { $('#loader').animate({opacity: 0.0}, 400, 'linear', function(){ // callback of fadeOut() $(this).load(newpage + ".php #toload", function(){ // callback of load() $('#loader').animate({opacity: 100.0}, 400, 'linear', function(){ //callback of fadeIn() // (not relevant for my problem, I think) $.getScript("js/test.js"); }); }); }); } My problem is: the first "animate" works like a charm but the second load the new content correctly, without the animation (a simple fadeIn). Anyone can help me? Thanks in advice! P.S. Sorry for my english

  • .NET Ascertaining mouse is on line drawn between two arbitrary points

    - by johnc
    I have an arrow drawn between two objects on a Winform. What would be the simplest way to determine that my mouse is currently hovering over, or near, this line. I have considered testing whether the mouse point intersects a square defined and extrapolated by the two points, however this would only be feasible if the two points had very similar x or y values. I am thinking, also, this problem is probably more in the realms of linear algebra rather than simple trigonometry, and whilst I do remember the simpler aspects of matrices, this problem is beyond my knowledge of linear algebra. On the other hand, if a .NET library can cope with the function, even better.

  • Algorithm Question.. Linked List..

    - by AGeek
    Hi, Scenario is as follows:- I want to reverse the direction of the singly linked list, In other words, after the reversal all pointers should now point backwards.. Well the algorithm should take linear time. The solution that i have thought of using another datastructure A Stack.. With the help of which the singly linked list would be easily reversed, with all pointers pointing backwards.. But i am in doubt, that whether the following implementation yeild linear time complexity.. Please comment on this.. And if any other efficient algorithm is in place, then please discuss.. Thanks.

  • Fast image coordinate lookup in Numpy

    - by victor
    I've got a big numpy array full of coordinates (about 400): [[102, 234], [304, 104], .... ] And a numpy 2d array my_map of size 800x800. What's the fastest way to look up the coordinates given in that array? I tried things like paletting as described in this post: http://opencvpython.blogspot.com/2012/06/fast-array-manipulation-in-numpy.html but couldn't get it to work. I was also thinking about turning each coordinate into a linear index of the map and then piping it straight into my_map like so: my_map[linearized_coords] but I couldn't get vectorize to properly translate the coordinates into a linear fashion. Any ideas?

  • Reason for different segments in Linux on x86

    - by anjruu
    Hey all, So, I know that Linux uses four default segments for an x86 processor (kernel code, kernel data, user code, user data), but they all have the same base and limit (0x00000000 and 0xfffff), meaning each segment maps to the same set of linear addresses. Given this, why even have user/kernel segments? I understand why there should be separate segments for code and data (just due to how the x86 processor deals with the cs and ds registers), but why not have a single code segment and a single data segment? Memory protection is done through paging, and the user and kernel segments map to the same linear addresses anyway. Thanks! anjruu

  • glTexParameter and filtering in OpenGL and GLSL?

    - by sharoz
    I have a couple questions about glTexParameter and filtering 1) What is the scope when applying a glTexParameter (specifically the filtering)? Here's a scenario: Bind a texture. Set the filters to LINEAR Set the texture to "Sampler1" of a shader Bind another texture. Set its filters to NEAREST Set that texture to "Sampler2" of a shader Draw When I use the textures in a shader, will one be linear and the other be nearest? Or will they both be nearest because it was called last? 2) Is it possible to set the filtering method in GLSL? Thanks in advance!

  • Performance of pixel shaders vs. SpriteBatch: XNA

    - by ashes999
    Precondition: I read this question/answer about using shaders, or spritebatch, to render and mark a sprite. I need to do something like that. I also have a 2D lighting PoC which I need to write. The way it will work will basically be something like: Draw all the sprites Draw lighting gradients to create a lighting texture Multiply/add the lighting texture to achieve different effects (I use multiple passes of add/multiply the lighting texture to achieve different effects.) My question is really about a generalization: can I say with certainty that pixel shaders are always faster than adding/multiplying textures to the SpriteBatch? Or that adding/multiplying is always faster? Or if it's not generalizable, how do I decide which approach to take, given that I can probably code either of them? (If it matters, I'm using MonoGame 3.0 beta for Windows games)
