• How to take a partial screen capture using Ruby?

  - by Jason

  Hi, I need to run a ruby client that wakes up every 10 minutes, takes a screen-shot (ss) of a users screen, crops part of the (ss) out and use's OCR to check for a matching word....its basically a program to make sure remote employees are actually working by checking that they have a specific application open & the case numbers shown change. Not sure where to even start when it comes to taking a screen-shot and cropping it, has anyone done any kind of screen capture work using Ruby? The app will run on OSX using Ruby 1.9 Thanks!

• Keep focus on blur event

  - by Jim

  I am using jquery to keep the focus on a text box when you click on a specific div. It works well in Internet Explorer but not in Firefox. Any suggestions? var clickedDiv = false; $('input').blur(function() { if (clickedDiv) { $('input').focus(); } }); $('div').mousedown(function() { clickedDiv = true; }) .mouseup(function() { clickedDiv = false }); If you need anymore specifics let me know.

• Ruby on rails - Radrails IDE - mysql issues.

  - by ThomasReggi

  I have been trying to get Ruby on Rails to migrate a database for the good part of today, the problems all seem to result with this issue, can someone please help! If its a radrails specific problem I guess Ill take this to their forums. Something is telling me this is an easy fix. >rake db:migrate (in C:/Users/Thomas/My Documents/Aptana RadRails Workspace/rp) !!! The bundled mysql.rb driver has been removed from Rails 2.2.

• Index was outside the bounds of the array. IndexOutOfRangeException in LINQ to SQL

  - by gtas

  Im getting this exception in the protected virtual void SendPropertyChanged(String propertyName) { if ((this.PropertyChanged != null)) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); <---- HERE !!! } } of one recently table association i created, there lots of same associations around the database, and this happened in the 4 specific tables i added. Its 1...* relationship and association is Primary Table - Id (identity auto generated) Foreign PId column int not null. I just dont get it....Im using SqlMetal for generation, i regenerated the schema, rebuild, same. This is causing while inserting row in DevExpress XtraGrid, but i dont think this should be issue, same control with same functionality but for different tables works ok. I use grid's event for append value in a property when the entity creating. I disabled this but same again. Recreated the association. No change, exception occurs. Any ideas?

• USB Serial cable with CDC support

  - by Harsha

  Hi All, I bought a USB to Serial cable which claims to be CDC compliant. But the bInterfaceClass value in interface descriptor is 0xFF(which is vendor specific). I was expecting it to be 0x02 (Communications and CDC control). In the device manager, i found that the drivers being loaded are ser2pl.sys and serenum.sys. I had learnt usbser.sys is the windows CDC driver, but it was not loaded for my cable. I am pretty much new to this CDC, so i have following questions 1.Does this indicate that the cable is not CDC compliant 2.Can i make this cable CDC compliant (since CDC is a driver functionality), by loading usbser.sys. If yes how?

• Deferred rendering with VSM - Scaling light depth loses moments

  - by user1423893

  I'm calculating my shadow term using a VSM method. This works correctly when using forward rendered lights but fails with deferred lights. // Shadow term (1 = no shadow) float shadow = 1; // [Light Space -> Shadow Map Space] // Transform the surface into light space and project // NB: Could be done in the vertex shader, but doing it here keeps the // "light shader" abstraction and doesn't limit the number of shadowed lights float4x4 LightViewProjection = mul(LightView, LightProjection); float4 surf_tex = mul(position, LightViewProjection); // Re-homogenize // 'w' component is not used in later calculations so no need to homogenize (it will equal '1' if homogenized) surf_tex.xyz /= surf_tex.w; // Rescale viewport to be [0,1] (texture coordinate system) float2 shadow_tex; shadow_tex.x = surf_tex.x * 0.5f + 0.5f; shadow_tex.y = -surf_tex.y * 0.5f + 0.5f; // Half texel offset //shadow_tex += (0.5 / 512); // Scaled distance to light (instead of 'surf_tex.z') float rescaled_dist_to_light = dist_to_light / LightAttenuation.y; //float rescaled_dist_to_light = surf_tex.z; // [Variance Shadow Map Depth Calculation] // No filtering float2 moments = tex2D(ShadowSampler, shadow_tex).xy; // Flip the moments values to bring them back to their original values moments.x = 1.0 - moments.x; moments.y = 1.0 - moments.y; // Compute variance float E_x2 = moments.y; float Ex_2 = moments.x * moments.x; float variance = E_x2 - Ex_2; variance = max(variance, Bias.y); // Surface is fully lit if the current pixel is before the light occluder (lit_factor == 1) // One-tailed inequality valid if float lit_factor = (rescaled_dist_to_light <= moments.x - Bias.x); // Compute probabilistic upper bound (mean distance) float m_d = moments.x - rescaled_dist_to_light; // Chebychev's inequality float p = variance / (variance + m_d * m_d); p = ReduceLightBleeding(p, Bias.z); // Adjust the light color based on the shadow attenuation shadow *= max(lit_factor, p); This is what I know for certain so far: The lighting is correct if I do not try and calculate the shadow term. (No shadows) The shadow term is correct when calculated using forward rendered lighting. (VSM works with forward rendered lights) With the current rescaled light distance (lightAttenuation.y is the far plane value): float rescaled_dist_to_light = dist_to_light / LightAttenuation.y; The light is correct and the shadow appears to be zoomed in and misses the blurring: When I do not rescale the light and use the homogenized 'surf_tex': float rescaled_dist_to_light = surf_tex.z; the shadows are blurred correctly but the lighting is incorrect and the cube model is no longer lit Why is scaling by the far plane value (LightAttenuation.y) zooming in too far? The only other factor involved is my world pixel position, which is calculated as follows: // [Position] float4 position; // [Screen Position] position.xy = input.PositionClone.xy; // Use 'x' and 'y' components already homogenized for uv coordinates above position.z = tex2D(DepthSampler, texCoord).r; // No need to homogenize 'z' component position.z = 1.0 - position.z; position.w = 1.0; // 1.0 = position.w / position.w // [World Position] position = mul(position, CameraViewProjectionInverse); // Re-homogenize position (xyz AND w, otherwise shadows will bend when camera is close) position.xyz /= position.w; position.w = 1.0; Using the inverse matrix of the camera's view x projection matrix does work for lighting but maybe it is incorrect for shadow calculation? EDIT: Light calculations for shadow including 'dist_to_light' // Work out the light position and direction in world space float3 light_position = float3(LightViewInverse._41, LightViewInverse._42, LightViewInverse._43); // Direction might need to be negated float3 light_direction = float3(-LightViewInverse._31, -LightViewInverse._32, -LightViewInverse._33); // Unnormalized light vector float3 dir_to_light = light_position - position; // Direction from vertex float dist_to_light = length(dir_to_light); // Normalise 'toLight' vector for lighting calculations dir_to_light = normalize(dir_to_light); EDIT2: These are the calculations for the moments (depth) //============================================= //---[Vertex Shaders]-------------------------- //============================================= DepthVSOutput depth_VS( float4 Position : POSITION, uniform float4x4 shadow_view, uniform float4x4 shadow_view_projection) { DepthVSOutput output = (DepthVSOutput)0; // First transform position into world space float4 position_world = mul(Position, World); output.position_screen = mul(position_world, shadow_view_projection); output.light_vec = mul(position_world, shadow_view).xyz; return output; } //============================================= //---[Pixel Shaders]--------------------------- //============================================= DepthPSOutput depth_PS(DepthVSOutput input) { DepthPSOutput output = (DepthPSOutput)0; // Work out the depth of this fragment from the light, normalized to [0, 1] float2 depth; depth.x = length(input.light_vec) / FarPlane; depth.y = depth.x * depth.x; // Flip depth values to avoid floating point inaccuracies depth.x = 1.0f - depth.x; depth.y = 1.0f - depth.y; output.depth = depth.xyxy; return output; } EDIT 3: I have tried the folloiwng: float4 pp; pp.xy = input.PositionClone.xy; // Use 'x' and 'y' components already homogenized for uv coordinates above pp.z = tex2D(DepthSampler, texCoord).r; // No need to homogenize 'z' component pp.z = 1.0 - pp.z; pp.w = 1.0; // 1.0 = position.w / position.w // Determine the depth of the pixel with respect to the light float4x4 LightViewProjection = mul(LightView, LightProjection); float4x4 matViewToLightViewProj = mul(CameraViewProjectionInverse, LightViewProjection); float4 vPositionLightCS = mul(pp, matViewToLightViewProj); float fLightDepth = vPositionLightCS.z / vPositionLightCS.w; // Transform from light space to shadow map texture space. float2 vShadowTexCoord = 0.5 * vPositionLightCS.xy / vPositionLightCS.w + float2(0.5f, 0.5f); vShadowTexCoord.y = 1.0f - vShadowTexCoord.y; // Offset the coordinate by half a texel so we sample it correctly vShadowTexCoord += (0.5f / 512); //g_vShadowMapSize This suffers the same problem as the second picture. I have tried storing the depth based on the view x projection matrix: output.position_screen = mul(position_world, shadow_view_projection); //output.light_vec = mul(position_world, shadow_view); output.light_vec = output.position_screen; depth.x = input.light_vec.z / input.light_vec.w; This gives a shadow that has lots surface acne due to horrible floating point precision errors. Everything is lit correctly though. EDIT 4: Found an OpenGL based tutorial here I have followed it to the letter and it would seem that the uv coordinates for looking up the shadow map are incorrect. The source uses a scaled matrix to get the uv coordinates for the shadow map sampler /// <summary> /// The scale matrix is used to push the projected vertex into the 0.0 - 1.0 region. /// Similar in role to a * 0.5 + 0.5, where -1.0 < a < 1.0. /// <summary> const float4x4 ScaleMatrix = float4x4 ( 0.5, 0.0, 0.0, 0.0, 0.0, -0.5, 0.0, 0.0, 0.0, 0.0, 0.5, 0.0, 0.5, 0.5, 0.5, 1.0 ); I had to negate the 0.5 for the y scaling (M22) in order for it to work but the shadowing is still not correct. Is this really the correct way to scale? float2 shadow_tex; shadow_tex.x = surf_tex.x * 0.5f + 0.5f; shadow_tex.y = surf_tex.y * -0.5f + 0.5f; The depth calculations are exactly the same as the source code yet they still do not work, which makes me believe something about the uv calculation above is incorrect.

• IE7 left:%; bug

  - by YuriKolovsky

  I'm working on a project, I use the latest IETester, and I bumped into a IE7 specific alignment bug. view this in IE7 and then in any other browser, for example Firefox, IE8 and even IE6. Notice how the little "|" between the lower links is not visible in IE7, yet it looks fine in the other browsers. Removing the left:-100%; from on line 61 fixes the bug as seen here, but i need this "left" for positioning. Any help on what is causing this bug, or potential ideas on how to fix it much needed.

• What's the best JSF implementation?

  - by Jeff

  Hey everyone, I currently have a medium size Java web application sitting on top of Spring MVC. As much as I like (no sarcasm) coding straight HTML, CSS and JS, it's not possible for me to develop as fast as I'd like. I'm looking at different RAD frameworks to speed up my development. I'm looking at JSF implementations and component libraries, Flex, GWT and a few others. As of now, Apache MyFaces (with ICEFaces) seems to be the front runner in my mind, but I'm curious to find out what you all think of that specific implementation and if the Sun implementation is any better? What's important to me is something that is stable, has an active community and that it doesn't look like there is another technology in the near future that is going to eclipse JSF (which would drive me to use a different RAD framework). Thanks in advance for the responses.

  To be more specific and less subjective: In what language are video games like Halo 3/COD 4/ mario cart written? Microsoft word for windows? for mac? The animation software used by big movie studios to make movies like toystory and monsters inc? The software that helps pilots control the F22 raptor? The software that watches the stock market? The software in the computer in my car? The software that makes the internet work? (this one is a bit vague, if more specificness is needed then google specifically) robots?

• Method signature Vs function prototype

  - by Maroloccio

  A formal definition of the two? Current Wiki articles denote their different contexts and applications, such as internal type signature "strings" in Java VMs (1) and C/C++ function prototypes informing compilers of upcoming method definitions (2) but... 1) http://en.wikipedia.org/wiki/Type_signature 2) http://en.wikipedia.org/wiki/Function_prototype ... where to look for a definition which clearly and formally distinguished one from the other? There is literature using the words prototype and signature almost interchangeably yet other uses appear strict and consistent, if language-specific. Background: I am writing documentation for a sample compiler written for a University project.

• Use ISAPI filter to trace and time a WCF call?

  - by Andrew Burke

  I'm building a web application using WCF that will be consumed by other applications as a service. Our app will be installed on a farm of web services and load balanced for scalability purposes. Occasionally we run into problems specific to one web server and we'd like to be able to determine from the response which web server the request was processed by and possibly timing information as well. For example, this request was processed by WebServer01 and the request took 200ms to finish. The first solution that came to mind was to build an ISAPI filter to add an HTTP header that stores this information in the response. This strikes me as the kind of thing somebody must have done before. Is there a better way to do this or an off-the-shelf ISAPI filter that I can use for this? Thanks in advance

• Get seconds since epoch in any POSIX compliant shell

  - by mattbh

  I'd like to know if there's a way to get the number of seconds since the UNIX epoch in any POSIX compliant shell, without resorting to non-POSIX languages like perl, or using non-POSIX extensions like GNU awk's strftime function. Here are some solutions I've already ruled out... date +%s // Doesn't work on Solaris I've seen some shell scripts suggested before, which parse the output of date then derive seconds from the formatted gregorian calendar date, but they don't seem to take details like leap seconds into account. GNU awk has the strftime function, but this isn't available in standard awk. I could write a small C program which calls the time function, but the binary would be specific to a particular architecture. Is there a cross platform way to do this using only POSIX compliant tools? I'm tempted to give up and accept a dependency on perl, which is at least widely deployed. perl -e 'print time' // Cheating (non-POSIX), but should work on most platforms

• How to turn off particular monitor with .NET?

  - by Boris

  OK, I know there are quite a few posts on this topic. However, none of them provide the solution to my issue: I don't want just to turn off my monitor(s), I wish my code to turn off a specific monitor. The URL the most people refer to, http://fci-h.blogspot.com/2007/03/turn-off-your-monitor-via-code-c.html, doesn't help here, as it turns off all the displays. So, I have my laptop screen and an additional external monitor. While I'm watching movies, I switch the display to the external monitor and my laptop screen goes black, however, it's still on and glowing in the dark. I wish to turn it off. Could anyone help please?

• IBM WebSphere vs Oracle Fusion

  - by Hal

  I have been asked to research the advantages/disadvantages the two application servers, but am new to the space and am having a terrible time finding an unbiased comparison of the two platforms. I understand that this is a broad question and I hate that I can't give a very specific use case (other than it will be an implementation in an organization with out a full time admin dedicated to management and it will be running in a mixed environment against JD Edwards/Oracle and SQLServer). Does anyone know of any (recently published) content that does a reasonable comparison or can any offer any insight into which might be the better choice and why. Any help would be greatly appreciated. Best regards, Hal

• The subscription model behind CSS selectors?

  - by Martin Kristiansen

  With CSS selectors a query string body > h1.span subscribes to a specific type of nodes in the tree. Does anyone know how this is done? Selectors for transformations, how does the browser select the result set? And is there a trick to making it efficient? I imagine there being some sort of hierarchical type-tree for the entire structure to which the nodes subscribe and which is what is used when doing the selector queries — but this is only a guess. Does anyone know the real answer? Or even more interesting, what would be the best way to do dynamic lookups on a tree based on jQuery/CSS search queries?

• Does RVM "failover" to another ruby instance on error?

  - by JohnMetta

  Have a strange problem in that I have a Rake task that seems to be using multiple versions of Ruby. When one fails, it seems to try another one. Details MacBook running 10.6.5 rvm 1.1.0 Rubies: 1.8.7-p302, ree-1.8.7-2010.02, ruby-1.9.2-p0 Rake 0.8.7 Gem 1.3.7 Veewee (provisioning Virtual Machines using Opcode.com, Vagrant and Chef) I'm not entirely sure the specific details of the error matter, but since it might be an issue with Veewee itself. So, what I'm trying to do is build a new box base on a veewee definition. The command fails with an error about a missing method- but what's interesting is how it fails. Errors I managed to figure out that if I only have one Ruby installed with RVM, it just fails. If I have more than one Ruby install, it fails at the same place, but execution seems to continue in another interpreter. Here are two different clipped console outputs. I've clipped them for size. The full outputs of each error are available as a gist. One Ruby version installed Here is the command run when I only have a single version of Ruby (1.8.7) available in RVM boudica:veewee john$ rvm rake build['mettabox'] --trace rvm 1.1.0 by Wayne E.

Prior to doing this, I used "rvm use 1.8.7." Again, I don't know how important the details of the specific errors are- what's interesting to me is that there are three separate errors- each with it's own stacktrace- and each in a different Ruby interpreter. Look at the bottom of each stacktrace and you'll see that they are all sourced from different interpreter locations- First ree-1.8.7, then ruby-1.8.7, then ruby-1.9.2: boudica:veewee john$ rvm rake build['mettabox'] --trace rvm 1.1.0 by Wayne E.

It seems strange to me that the first exception would not halt execution as it did with one interpreter, but I wonder if there are things happening when RVM is installed that we Ruby developers are not considering.

• Face recognition Library

  - by Janusz

  I'm looking for a free face recognition library for a university project. I'm not looking for face detection. I'm looking for actual recognition. That means finding images that contain specified faces or libraries that calculate distances between specific faces. I'm using OpenCV for detecting the faces and a rough Eigenfaces Algorithm for the recognition now. But I thought there should be something out there with a better performance then a self written Eigenfaces Algorithm. I don't talk about speed as performance I'm looking for a library with better results as an simple Eigenfaces approach I took a look at faint but it seems the library is not very reusable for my own applications. I'm happy with a library in Python, Java, C++, C or something like that. The best thing would be if it can be run on a Windowsmachine

• using WP_Query with custom SQL in wordpress

  - by Matt Facer

  Hi. I am writing a plugin for wordpress and I want to create my own search. I have tried to alter the wordpress search, but what I am doing is very specific with the SQL query. I am comparing lat and long coordinates and getting posts based on that. I can display posts by using the standard wpdb query, but then I don't get the other features like paging. I'd like to be able to use my SQL statement with the WP_Query function. If I'm right in thinking, I should then be able to use the paging and other features which come from the $posts global variable. Is this right?? I've googled for hours but can't find anything for plugins outside of using args to select categories etc. I simply need to send a complete SQL command - nothing else. Many thanks....

• Mobile phone - configuration via SMS

  - by vpdn

  In Germany, mobile carriers often provide a simple way to configure your mobile phone for MMS and GPRS: After keying in your phone number and device model on the carrier's website, you get a "configuration sms" sent to you. I'm trying to understand how that works from a technical standpoint. I have scanned through 3GPP TS 03.40 (http://www.3gpp.org/ftp/Specs/html-info/0340.htm), but haven't been able to find much. Also, the fact that one has to provide the phone model indicates that it is a provider specific thing and not standardized? Does anyone have any pointers for me? Also I'd be interested how the "internet-enabling" process looks like in other countries. Anyone care to share?

• Entity Framework Vote of No Confidence - relevant in .NET 4?

  - by Asaf R

  Hi, I'm deciding on an ORM for a big project and was determined to go for ADO.NET Entity Framework, specifically its new version that ships with .NET 4. During my search for information on EF I stumbled upon ADO .NET Entity Framework Vote of No Confidence which I'm not sure how to take. The Vote of No Confidence was written sometime in 2008 to convince Microsoft to listen to specific criticism for EF v1. It's not clear whether the claims made in the Vote of No Confidence are still valid (in .NET 4) and if they're serious enough to use other solutions. NHibernate is a mature alternative, but I don't know what problems it brings. I'm generally more inclined towards a Ms solution, mainly because I can count on integration with VS and on their developer support. I would appreciate examples of how the problems mentioned in the Vote of No Confidence affect in real world projects. More importantly, are the claims made there still relevant in EF for .NET 4? Thanks, Asaf

• JavaScript: 'textarea.value' not working in IE?

  - by pete

  Hi! A few hours ago, I was instructed how to style a specific textarea with JS. The following piece of code (thanks again, Mario Menger) works like a charm in Firefox but unfortunately nothing happens in Internet Explorer (7 tested only so far). var foo = document.getElementById('HCB_textarea'); var defaultText = 'Your message here'; foo.value = defaultText; foo.style.color = '#888'; foo.onfocus = function(){ foo.style.color = '#000'; if ( foo.value == defaultText ) { foo.value = ''; } }; foo.onblur = function(){ foo.style.color = '#888'; if ( foo.value == '' ) { foo.value = defaultText; } }; I've already tried to replace 'value' by 'innerHTML' (for IE only) but to no effect. Any suggestions? TIA
