• Contractor - Mispaid again - Walked out

  - by MeshMan

  Hi all, I'm wondering whether or not I've done the right thing as a contractor. Basically I'm in to my 3rd month, and my current client messed up the payment in the first month, and I just found out that they are again late in paying me for my 2nd month. It wouldn't be so bad if I wasn't in a bit of a financial situation due to this being my first contract experience. But as a matter of principal, I walked out on them and will be telling them that I will not be going back in until they resolve the pay. Part of me feels as though this was not a very professional thing to do, but I also don't feel that it was very professional for them to mess my payments up, twice in a row. Did I make the right decision? I still want to work for these guys and enjoy the job, but I have a life to attend to that requires finances and I can't afford to keep getting messed up with pay like this. I attempted to phrase the question to be oriented around contractors behaviour around clients that mis-treat them, and as some of the answers that have been posted so far, it's a good discussion. The answers coming in are great around different subjective situations.

• How can I create an orthographic display that handles different screen dimensions?

  - by Piku

  I'm trying to create an iPad/iPhone game using GLES2.0 that contains a 3D scene with a heads-up-display/GUI overlaid on the top. However, this problem would also apply if I were to port my game to a computer and run the game in a resizable window, or allow the user to change screen resolutions... When trying to make the 2D GUI/HUD work I've made the assumption that all I'm really doing is drawing a load of 2D textured 'quads' on the screen and am trying to treat the orthographic projection as an old-style 2D display with 0,0 in the upper left and screenWidth,ScreenHeight in the lower right. This causes me all sorts of confusion when I rotate my ipad into Landscape mode since I can't work out what to put into my projection and modelview matrices to turn everything around the right way. It also gets messy if I want to support the iPad's large screen, an iPhone or a Retina display since I have to then draw three sets of textures for everything and work out which ones to use. Should I be trying to map the 2D OpenGL co-ords 1:1 with the screen? While typing out this question it occurs to me that I could keep my origin in the centre, still running -1/+1 along the axes. This would let me scale my 2D content appropriately on the different screen sizes, but wouldn't I end up with the textures being scaled and possibly losing quality? I'm using OpenGLES 2.0 and have a matrix library that has equivalents to the GLES1.1 glOrthof() and glFrustrum() calls.

• Make Gameobject Stand On Surface Facing Certain Direction

  - by Julian

  I want to make a biped character stand on any surface I click on. Surfaces have up vectors of any of positive or negative X,Y,Z. So imagine a cube with each face being a gameobject whose up vector pointing directly away from the cube. If my character is facing "forward" and I click on a surface which is to the left or right of me ( left or right walls), I want my character to now be standing on that surface but still be facing in the direction he initially was. If I click on a wall which is in the forward path of my character i want him to now be standing on that surface and his forward to now be what was once "up" relative to my character. Here is the code I am working with now. void Update() { if (Input.GetMouseButtonUp (0)) { RaycastHit hit; var ray = Camera.main.ScreenPointToRay(Input.mousePosition); if (Physics.Raycast(ray, out hit)) { Vector3 upVectBefore = transform.up; Vector3 forwardVectBefore = transform.forward; Quaternion rotationVectBefore = transform.rotation; Vector3 hitPosition = hit.transform.position; transform.position = hitPosition; float lookDifference = Vector3.Distance(hit.transform.up, forwardVectBefore); if(Vector3.Distance(hit.transform.up, upVectBefore) < .23) //Same normal { transform.rotation = rotationVectBefore; } else if(lookDifference > 1.412 && lookDifference <= 1.70607) //side wall { transform.up = hit.transform.up; transform.forward = forwardVectBefore; } else //head on wall { transform.up = hit.transform.up; transform.forward = upVectBefore; } } } } The first case "Same normal" works fine, however the other two do not work as I would like them to. Sometimes my character is laying down on the surface or on the wrong side of the surface. Does anyone know nice way of solving this problem?

• Google is displaying "Translate this page" based on a previously registered domain inbound links

  - by crnm

  I recently started a new project with a newly registered generic tld domain. As soon as Google started indexing the page, it displayed a "translate this page" in SERP's, which tries to translate the page to the language of a small Eastern European country from the language that the site actually uses. I tried everything to prevent this: language meta headers and attributes, localisation through Google Webmaster Tools...all to no avail - nothing helped. After a couple of weeks I spotted dozens of inbound links popping up in Google Webmaster Tools all coming from that small Eastern European country, from sub-pages that are not active anymore (either sending out 404's or 301's to the main page), and also had been written in that other language. So the domain had been registered before and as it looks, it did got a lot of possibly spam links in that language. I can't even ask the sites where those links should have been to remove them as they are not active anymore physically, just in Google Webmaster Tools and/or internal data masses... Now I'm at a loss about what to do? As my site is pretty new, it does not have many links pointing towards it in my targeted language. So those are probably not enough to convince Google of attaching the right language to it as Google ignores all other signals about the page language. I'm also unsure if I should use the "disavow" tool, or a reconsideration request...or what else to do about this miserable state. I never used these tools before so I don't have any experience with them. Somehow I have to convince Google about the right language of the page and also to not count/apply/whatever all those historical links from the previous owner. (The domain had been deleted without any traces in Google before I registered it) Has anyone here ever dealt with a similar "Translate this page" problem? (I've also looked at this thread: How can I prevent Google mistakenly offering to translate a page? but didn't find a solution there)

• JEditorPane on Steroids with Nashorn

  - by Geertjan

  Continuing from Embedded Nashorn in JEditorPane, here is the same JEditorPane on steroids with Nashorn, in the context of some kind of CMS backend system: Above, you see heavy reusage of NetBeans IDE editor infrastructure. Parts of it are with thanks to Steven Yi, who has done some great research in this area. Code completion, right-click popup menu, line numbering, editor toolbar, find/replace features, block selection, comment/uncomment features, etc, etc, etc, all the rich editor features from NetBeans IDE are there, within a plain old JEditorPane. And everything is externally extensible, e.g., new actions can be registered by external modules into the right-click popup menu or the editor toolbar or the sidebar, etc. For example, here's code completion (Ctrl-Space): It even has the cool new feature where if you select a closing brace and the opening brace isn't in the visible area, a rectangular popup appears at the top of the editor, to show how the current piece of code begins: The only thing I am missing is code folding! I wish that would work too, still figuring it out. What's also cool is that this is a Maven project.

• Should I make up my own HTTP status codes? (a la Twitter 420: Enhance Your Calm)

  - by Max Bucknell

  I'm currently implementing an HTTP API, my first ever. I've been spending a lot of time looking at the Wikipedia page for HTTP status codes, because I'm determined to implement the right codes for the right situations. Listed on that page is a code with number 420, which is a custom code that Twitter used to use for rate limiting. There is already a code for rate limiting, though. It's 429. This led me to wonder why they would set a custom one, when there is already a use case. Is that just being cute? And if so, then which circumstances would make it acceptable to return a different status code, and what, if any problems may clients have with it? I read somewhere that Mozilla doesn't implement the joke 418: I’m a teapot response, which makes me think that clients choose which status codes they implement. If that's true, then I can imagine Twitter's funny little enhance your calm code being problematic. Unless I'm mistaken, and we can appropriate any code number to mean whatever we like, and that only convention dictates that 404 means not found, and 429 means take it easy.

• F# Application Entry Point

  - by MarkPearl

  Up to now I have been looking at F# for modular solutions, but have never considered writing an end to end application. Today I was wondering how one would even start to write an end to end application and realized that I didn’t even know where the entry point is for an F# application. After browsing MSDN a bit I got a basic example of a F# application with an entry point [<EntryPoint>] let main args = printfn "Arguments passed to function : %A" args // Return 0. This indicates success. 0 Pretty simple stuff… but what happens when you have a few modules in a program – so I created a F# project with two modules and a main module as illustrated in the image below… When I try to compile my program I get a build error… A function labeled with the 'EntryPointAttribute' attribute must be the last declaration in the last file in the compilation sequence, and can only be used when compiling to a .exe… What does this mean? After some more reading I discovered that the Program.fs needs to be the last file in the F# application – the order of the files in a F# solution are important. How do I move a source file up or down? I tried dragging the Program.fs file below ModuleB.fs but it wouldn’t allow me to. Then I thought to right click on a source file and got the following menu.   Wala… to move the source file to the bottom of the solution you can select the “Move Up” or “Move Down” option. Now that I got this right I decided to put some code in ModuleA & ModuleB and I have the start of a basic application structure. ModuleA Code namespace MyApp module ModuleA = let PrintModuleA = printf "hello a \n" ()   ModuleB Code namespace MyApp module ModuleB = let PrintModuleB = printf "hello b \n" ()   Program Code // Learn more about F# at http://fsharp.net #light namespace MyApp module Main = open System [<EntryPoint>] let main args = ModuleA.PrintModuleA let endofapp = Console.ReadKey() 0

• When NOT to use a framework

  - by Chris

  Today, one can find a framework for just about any language, to suit just about any project. Most modern frameworks are fairly robust (generally speaking), with hour upon hour of testing, peer reviewed code, and great extensibility. However, I think there is a downside to ANY framework in that programmers, as a community, may become so reliant upon their chosen frameworks that they no longer understand the underlying workings, or in the case of newer programmers, never learn the underlying workings to begin with. It is easy to become specialized to a degree that you are no longer a 'PHP programmer' (for example), but a "Drupal programmer", to the exclusion of anything else. Who cares, right? We have the framework! We don't need to know how to "do it by hand"! Right? The result of this loss of basic skills (sometimes to the extent that programmers who don't use frameworks are viewed as "outdated") is that it becomes common practice to use a framework where it is not required or appropriate. The features the framework facilitates wind up confused with what the base language is capable of. Developers start using frameworks to accomplish even the most basic of tasks, so that what once was considered a rudimentary process now involves large libraries with their own quirks, bugs, and dependencies. What was once accomplished in 20 lines is now accomplished by including a 20,000 line framework AND writing 20 lines to use the framework. Conversely, one does not want to reinvent the wheel. If I'm writing code to accomplish some basic, common little task, I might feel like I am wasting my time when I know that framework XYZ offers all the features I am after, and a whole lot more. The "whole lot more" part still has me worried, but it doesn't seem that many even consider it anymore. There has to be a good metric to determine when it is appropriate to use a framework. What do you consider the threshold to be, how do you decide when to use a framework, or, when not.

• Point an external domain to a shared hosting website

  - by dailgez004

  I bought a domain from a seller (GoDaddy), and wish to point it at a shared hosting website (ASmallOrange). Googling tells me it's fairly straightforward: Step 1: On the external domain's DNS, configure two NS records for the two nameservers of the hosting service. Step 2: Wait 2-48 hours. I'm puzzled because it can't be that simple. I've told the DNS where to look, but since it's shared hosting, the hosting service needs to know what site to point the domain to. And indeed, after I've performed the above steps, visiting the domain leads me to a generic message from the shared hosting service. Okay, so I have to configure the DNS on the hosting service, right? The service I use (ASmallOrange) uses cPanel. What I tried is to set up a Parked Domain for the externally bought domain; when I go into the Advanced DNS Zone Editor, sure enough, the DNS for the external domain shows up as something I can configure. Yet, visiting the externally registered domain still points me to the generic shared server page. I'm convinced I'm doing something wrong. Could someone debug my thought process? Or perhaps offer alternate solutions? Right now, I'm considering trying to set up a CNAME record on the external domain to point to the domain I registered through the shared host -- but I have a vague impression that this is bad practice.

• Drawing Grid in 3D view - Mathematically calculate points and draw line between them (Not working)

  - by Deukalion

  I'm trying to draw a simple grid from a starting point and expand it to a size. Doing this mathematically and drawing the lines between each point, but since the "DrawPrimitives(LineList)" doesn't work the way it should work, And this method can't even draw lines between four points to create a simple Rectangle, so how does this method work exactly? Some sort of coordinate system: [ ][ ][ ][ ][ ][ ][ ] [ ][2.2][ ][0.2][ ][2.2][ ] [ ][2.1][1.1][ ][1.1][2.1][ ] [ ][2.0][ ][0.0][ ][2.0][ ] [ ][2.1][1.1][ ][1.1][2.1][ ] [ ][2.2][ ][0.2][ ][2.2][ ] [ ][ ][ ][ ][ ][ ][ ] I've checked with my method and it's working as it should. It calculates all the points to form a grid. This way I should be able to create Points where to draw line right? This way, if I supply the method with Size = 2 it starts at 0,0 and works it through all the corners (2,2) on each side. So, I have the positions of each point. How do I draw lines between these? VerticeCount = must be number of Points in this case, right? So, tell me, if I can't supply this method with Point A, Point B, Point C, Point D to draw a four vertice rectangle (Point A - B - C - D) - how do I do it? How do I even begin to understand it? As far as I'm concered, that's a "Line list" or a list of points where to draw lines. Can anyone explain what I'm missing? I wish to do this mathematically so I can create a a custom grid that can be altered.

• Dealing with numerous, simultaneous sounds in unity

  - by luxchar

  I've written a custom class that creates a fixed number of audio sources. When a new sound is played, it goes through the class, which creates a queue of sounds that will be played during that frame. The sounds that are closer to the camera are given preference. If new sounds arrive in the next frame, I have a complex set of rules that determines how to replace the old ones. Ideally, "big" or "important" sounds should not be replaced by small ones. Sound replacement is necessary since the game can be fast-paced at times, and should try to play new sounds by replacing old ones. Otherwise, there can be "silent" moments when an old sound is about to stop playing and isn't replaced right away by a new sound. The drawback of replacing old sounds right away is that there is a harsh transition from the old sound clip to the new one. But I wonder if I could just remove that management logic altogether, and create audio sources on the fly for new sounds. I could give "important" sounds more priority (closer to 0 in the corresponding property) as opposed to less important ones, and let Unity take care of culling out sound effects that exceed the channel limit. The only drawback is that it requires many heap allocations. I wonder what strategy people use here?

• C# XNA 2D Multiple boxes collision detection and movement

  - by zini

  Hi, I've been making simple game where you shoot boxes that are coming towards you. All game objects are simple rectangles. Now I have problem with collision detection; how to check where the collision comes so I can change the coordinates right? I have this kind of situation: http://imgur.com/8yjfW Imagine that all of those blocks are moving towards you (green box). If those orange boxes collide with each other, they should "avoid" themselves and not go through each other. I have class Enemy which has properties x, y and such. Now I'm doing the collision like this: // os.Count is an amount of other enemies colliding with this enemy if (os.Count == 0) { // If enemy doesn't collide with other enemy lasty = y; lastx = x; slope = (x - player.x) / (y - player.y); x += slope * l; // l is "movement speed" of enemy (float) if (y > player.y) { y = lasty; } else if (y < player.y) { y += l; } } else { foreach(Enemy b in os) { if (b.y > this.y) { // If some colliding enemy is closer player than this enemy, that closer one will be moved towards the player b.lasty = b.y; if (!BiggestY(os)) { // BiggestY returns true if this enemy has the biggest Y b.y += b.l; } b.x = b.lastx; } } } But this is very, very bad way to do this. I know it, but I just can't figure out other way. And as a matter in fact, this method doesn't even work pretty good; if multiple enemies are colliding same enemy they go through each other. I explained this pretty badly, but I hope that you understand this. And to sum up, as I said: How to check where the collision comes so I can change the coordinates right?

• iOS - UISlider - How to make a slider to auto-move [closed]

  - by drodri420

  its me again. Coming back with another noobish question: This time its , can you make a UISlider move by itself??? I've implemented this on the .m ///This right here makes a slider move 1point from 1 to 100, once it reaches 100 it goes backwards and so on... - (IBAction)moveSlider:(UISlider *)sender { int flag=0, counter=1; while(flag == 0) { counter = counter + (.25 * round); if(counter == 100) { flag = 1; } if(counter < 100 && counter > 1) { slider.value = counter; } } while(flag == 1) { counter = counter - (.25 * round); if(counter == 1) { flag = 0; } if(counter < 100 && counter > 1) { slider.value = counter; } } } And Implemented this on another action: -(void)startNewRound { round+=1; targetValue = 1 + (arc4random() % 100); self.slider.value = currentValue; [self moveSlider:slider]; } I think I lost it along the way and Im just typing pure nonsense but If anyone could point me in the right direction on to which is it that Im doing wrong??

• Working with Google Webmaster Tools

  - by com

  My first question is about Crawl errors in Google Webmaster Tools. Crawl errors is devided into few sections. One of them is HTTP. I assume that all broken links in HTTP was somehow found by crawler, this is not the links from sitemap. If this was found by scanning all sitemap pages for links, why it doesn't mention what was the source page, like in sitemap section with column Linked From. And what the meaning of Linked From, I thought if the name of section is sitemap, therefore all URLs should be taken from sitemap, so why there is Linked From? The second question, what is the best way to trreat searching on the site. How come the searching result page are getting indexed? Because of the fact that all searching result page are getting indexed, I have to many page in Linked From. What's the right practice? Question three: In order to improve response time in WMT, can I redirect all crawler's requests to designated free web server? Is this good practice? Question four: How should I treat Google Analytics Code (with parameters PageView, PageLoadTime), in the case user request non existing page, should I render Google code or not? Right now I use Google Analytics Code on the common template page, such that every page, also non existing page with error message contains Google Analytics Code, it seems like it has influence on WMT.

• How to ask developers to think about high resolution screens

  - by WhiteWind

  I just got a ASUS N56VZ laptop, and it`s all good, but the screen resolution 1920x1080px. I am not asking, how to scale ui elements. If someone is interested I have found some tricks: increase font size in system settings increase unity dock size in MyUnity or system settings in modern Ubuntu versions. tweak userChrome.js of FireFox to make buttons|panels|icons larger add DefaultZoomLevel extension to FireFox to make it zoom pages initially. But all of it is miserable, because there are some big bugs: window decoration elements are way too small to pick them with mouse. I can't scale window easily and I can't position my cursor fast on the close|maximize buttons. Tuning lines like in sound volume dialog are hardly clickable at all. Unity top panel (status panel & tray) hardly can contain the bigger font, so it looks ugly, but icons are still the same. Sometimes I can`t read text, as it is cropped (and I cant scale some dialogs as it has fixed size) Chromium is not usable at all (ok, it's not Ubuntu problem, but the problem still exists) JAVA applications are not scalable (same as above) In FF I am able to get descent results in most cases, but multiplication of system font increase and browser font increase makes system controls (combobox, lists, drop down lists) extremely big, so I cant even control the zoom level on the page. IMHO, we should post a bug report (but what kind of bug?) and vote for it! The problem is even deeper, but at least we should ask developers to think about it. So my question is: how can I post a report (the right words and right place) and how can we (who already has that problem, or who want it to be solved before hardware upgrade) vote for faster solution. Any ideas?

• What is causing this behavior with the movement of Pong Ball in 2D? [closed]

  - by thegermanpole

  //edit after running it through the debugger it turned out i had the display function set to x,x...TIL how to use a debugger I've been trying to teach myself C++ SDL with the lazyfoo tutorial and seem to have run into a roadblock. The code below is the movement function of my Dot class, which controls the ball. The ball seems to ignore yvel and moves with xvel to the bottom right. The code should be pretty readable, the rest of the relevant facts are: All variables are names Constants are in caps dotrad is the radius of my dot yvel and xvel are set to 5 in the constructor The dot is created at x and y equal to 100 When I comment out the x movement block it doesn't move, but if i comment out the y movement block, it keeps on going down to the right. void Dot::move() { if(((y+yvel+dotrad) <= SCREEN_HEIGHT) && (0 <= (y-dotrad+yvel))) { y+=yvel; } else { yvel = -1*yvel; } if(((x+xvel+dotrad) <= SCREEN_WIDTH) && (0 <= (x-dotrad+xvel))) { x +=xvel; } else { xvel = -1*xvel; } }

• Is there a way how to customize my keyboard layout in Xubuntu in a graphical way (by clicking)?

  - by Honza Javorek

  Possible duplicate, but I really couldn't find a solution. I would like to adjust my US keyboard layout, e.g. to add possibility to type some special characters on combination of right Alt + another character, etc. Moreover, my arrow up is dead, so until I buy another keyboard, I'd like to use my right shift as my arrow up, ASAP. However, there seems to be no way how to edit my keyboard layout easily in Xubuntu :( I found no editor and I really don't want to spend years in some configuration files and terminal (not that I can't, but I really really don't want). KLE - the only editor I could find, but no installation guide, no package, no PPA, no idea how to make it working (and uninstallable if not needed one day) Editor in Ubuntu - apparently not present in Xubuntu I found several tutorials how to change the layout, but they all seems to be complicated and not easy to follow. I don't want to spend a weekend in terminal or so, I am looking for an app to launch, make some clicking, finish my work by hitting Save button and - done! Please, is there such solution? For humans?

• How to modify partitions after install?

  - by ChocoDeveloper

  I wanted to have Ubuntu with full disk encryption on one big partition, and Windows on a small one. In 12.04, only the Server Edition installer has full disk encryption, so I used that and then installed ubuntu-desktop. When it asked for the size, I reduced it from ~999GB to ~750gb. Now after the install, on both gparted and disk utility I see /dev/sda2 taking ~931GB, and nothing unallocated, so I can't create a partition for windows. I got the size right, because when I right-click inside a folder, then hit 'properties', I see Free space: ~690GB (I don't know why it's not ~750GB, but at least it's not 900). The command df -h shows the same. So what can I do? Normally I would just resize a partition with gparted to create unallocated space, then create the partition. But here I have two problems: gparted does not seem to be showing the correct values, and also it says it does not support LUKS so I'm afraid it will mess things up. Any thoughts?

• menu not showing in apps when maximized 12.10

  - by chazdg

  I have removed the Global App Menu as I prefer to have the minimize, maximize, close buttons on the right side of each app. I did this with no problem in 12.04. I did an upgrade to 12.10 and noticed that Chrome, Chromium and Firefox all use the Global Menu. I have done the following: sudo apt-get autoremove appmenu-gtk appmenu-gtk3 appmenu-qt I have disabled the Firefox extension. I removed the corresponding Firefox package but still only have a global menu. I tried Gconf but apparently that does not work in 12.10. I then tried Dconf and found this fix on Google: org gnome desktop wm preferences, look for "button_layout" on the right panel. Here is the problem, after desktop, I do not have wm. I reset Unity and got a message saying something about wm is missing. I rebooted and opened Chrome and still no fix. I then clicked maximize and once Chrome was not maximized anymore, the minimize, maximize, close buttons show up in Chrome. Same with Firefox! Any ideas? I am truly stumped. Firefox and Chrome work fine in KDE Plasma and Gnome when maximized.

• 3d point cloud render from x,y,z 2d array with texture

  - by user1733628

  Need some direction on 3d point cloud display using OpenGL in c++ (vs2008). I am brand new to OpenGL and trying to do a 3d point cloud display with a texture. I have 3 2D arrays (each same size 1024x512) representing x,y,z of each point. I think I am on the right track with glBegin(GL_POLYGON); for(int i=0; i<1024; i++) { for(int j=0; j<512; j++) { glVertex3f(x[i][j], y[i][j], z[i][j]); } } glEnd(); Now this loads all the vertices in the buffer (I think) but from here I am not sure how to proceed. Or I am completely wrong here. Then I have another 2D array (same size) that contains color data (values from 0-255) that I want to use as texture on the 3D point cloud and display. I understand that this maybe a very basic OpenGL implementation for some but for me this is a huge learning curve. So any pointers, nudge or kick in the right direction will be appreciated.

• How do I daemonify my daemon?

  - by jonobacon

  As part of the Ubuntu Accomplishments system I have a daemon that runs as well as a client that connects to it. The daemon is written in Python (using Twisted) and provides a dbus service and a means of processing requests from the clients. Right now the daemon is just a program I run before I run the client and it sets up the dbus service and provides an API that can be used by the clients. I want to transform this into something that can be installed and run as a system service for the user's session (e.g. starting on boot) and providing a means to start and stop it etc. The problem is, I am not sure what I need to do to properly daemonify it so it can run as this service. I wanted to ask if others can provide some guidance. Some things I need to ask: How can I treat it as a service that is run for the current user service (not a system service right now)? How do I ensure I can start, stop, and restart this session service? When packaging this, how do I ensure that it installs it as a service for the user's session and is started on login etc? In responding, if you can point me to specific examples or solutions I need to implement, that would be helpful. :-) Thanks! Jono

• Rendering multiple squares fast?

  - by Sam

  so I'm doing my first steps with openGL development on android and I'm kinda stuck at some serious performance issues... What I'm trying to do is render a whole grid of single colored squares on to the screen and I'm getting framerates of ~7FPS. The squares are 9px in size right now with one pixel border in between, so I get a few thousand of them. I have a class "Square" and the Renderer iterates over all Squares every frame and calls the draw() method of each (just the iteration is fast enough, with no openGL code the whole thing runs smootlhy at 60FPS). Right now the draw() method looks like this: // Prepare the square coordinate data GLES20.glVertexAttribPointer(mPositionHandle, COORDS_PER_VERTEX, GLES20.GL_FLOAT, false, vertexStride, vertexBuffer); // Set color for drawing the square GLES20.glUniform4fv(mColorHandle, 1, color, 0); // Draw the square GLES20.glDrawElements(GLES20.GL_TRIANGLES, drawOrder.length, GLES20.GL_UNSIGNED_SHORT, drawListBuffer); So its actually only 3 openGL calls. Everything else (loading shaders, filling buffers, getting appropriate handles, etc.) is done in the Constructor and things like the Program and the handles are also static attributes. What am I missing here, why is it rendering so slow? I've also tried loading the buffer data into VBOs, but this is actually slower... Maybe I did something wrong though. Any help greatly appreciated! :)

• Incremental search in Visual Studio

  - by Jalpesh P. Vadgama

  Visual studio is a Great IDE and there are still lots of feature that not known to developers. Incremental search is one of them. This is a amazing feature to find code in particular document and its available from Visual Studio 2010 and carried over in Visual Studio 2012. Incremental search allows developers to search in document without blocking UI and allow to search as they type. Interesting!! right.. So let’s open visual studio and see how it works. Once you open Visual Studio and press Ctrl + I and type something it will find the string without blocking your visual studio UI. Just like following. In the above code you can see that, I have typed Cons and You can see that whole console word is highlighted. Even you can see that find dialog box on top right corner of visual studio 2012 like following. Same way if you see the footer in visual studio where it is finding cons in current document like following. Isn’t that great now we find things very easily and we don’t have to remember whole word like Console. Hope you like it. Stay tuned for more updates.

• Google Chrome with strange behavior

  - by user72274

  I'm former Chromium-browser user, but after not upgrading the PPA for 2 months, I switched to Google Chrome browser yesterday. Everything is okay, except some strange behavior on some pages and crashing after loading "chrome://" configuration pages. The best known website with strange behavior is youtube, there is a picture what I see: When I open user menu in top right corner, it crashes that way and even after closing the menu, some parts of menu stay display. You may say it's Youtube problem, no, I have this problem at least on three other websites, here it is on Imgur: The problem isn't for the whole side, sometimes it happens from the middle of the screen. The interesting part is that it happens everytime in the same distance from the right border. When I check the DOM elements with the Developer tool, the overlay which shows element's position is rendered how it should be. What is more, if there is anchor after the crashed area, it works after clicking on it. Selecting text in crashed page is impossible. I hope there is enough information to give me an advice, thanks in advance. :) EDIT: Here is what the browser posted in "chrome://gpu-internals/": Graphics Feature Status Canvas: Software only, hardware acceleration unavailable Compositing: Hardware accelerated 3D CSS: Hardware accelerated CSS Animation: Software animated. WebGL: Hardware accelerated WebGL multisampling: Hardware accelerated Problems Detected Accelerated CSS animation has been disabled at the command line.
