VBO and shaders confusion, what's their connection?

- by Jeffrey

Considering OpenGL 2.1 VBOs and 1.20 GLSL shaders: When creating an entity like "Zombie", is it good to initialize just the VBO buffer with the data once and do N glDrawArrays() calls per each N zombies? Is there a more efficient way? (With a single call we cannot pass different uniforms to the shader to calculate an offset, see point 3) When dealing with logical object (player, tree, cube etc), should I always use the same shader or should I customize (or be able to customize) the shaders per each object? Considering an entity class, should I create and define the shader at object initialization? When having a movable object such as a human, is there any more powerful way to deal with its coordinates than to initialize its VBO object at 0,0 and define an uniform offset to pass to the shader to calculate its real position? Could you make an example of the Data Oriented Design on creating a generic zombie class? Is the following good? Zombielist class: class ZombieList { GLuint vbo; // generic zombie vertex model std::vector<color>; // object default color std::vector<texture>; // objects textures std::vector<vector3D>; // objects positions public: unsigned int create(); // return object id void move(unsigned int objId, vector3D offset); void rotate(unsigned int objId, float angle); void setColor(unsigned int objId, color c); void setPosition(unsigned int objId, color c); void setTexture(unsigned int, unsigned int); ... void update(Player*); // move towards player, attack if near } Example: Player p; Zombielist zl; unsigned int first = zl.create(); zl.setPosition(first, vector3D(50, 50)); zl.setTexture(first, texture("zombie1.png")); ... while (running) { // main loop ... zl.update(&p); zl.draw(); // draw every zombie }

Implement Budget Allocation in DAX for Power Pivot and Tabular #powerpivot #tabular #ssas #dax

- by Marco Russo (SQLBI)

Comparing sales and budget, or costs and budget, is a very common operation. However, it is often the case that you have different granularities for different tables containing budget and the data to compare with. There are two ways to do that: you can limit the comparison to the granularity that is common to the two tables, or you can allocate the budget where it’s not defined. For example, if you have a budget defined by quarter and category, you might want to allocate it by month and product. In this way, you will do the comparison as you had a more granular definition of the budget, without actually having to do the manual job of allocating data (usually in an Excel worksheet!). If you want to do budget allocation in DAX, you can use the Budget Patterns we published on DAX Patterns. If you come from and MDX/OLAP background, at first you might find it hard to solve the problem of not having attribute hierarchies that helps you in propagating the budget values to lower hierarchical levels. However, I think that once you get used to DAX, you will find the behavior very predictable and easy to “debug” also for more complex allocation formula. You just have to be careful in writing the DAX formula, but probably the pattern we wrote should help you designing the right data model, without creating physical relationships to the budget table! This pattern is also based on the Handling Different Granularities scenario I discussed a couple of weeks ago.

Ignore Partial Upgrade -- Google Earth Dependencies

- by pyraz

I'm running a 64-bit install of Xubuntu 12.04. It took me a little while to get Google Earth working. The 64-bit Google earth package requires some 32-bit gtk libraries provided by ia32-libs. However, when I ran a simulation to install ia32-libs and it's dependencies, it wanted to remove a ton of programs, including the xubuntu-desktop meta-package. As a work-around, I used getlibs to get the 32-bit libraries I needed, and then installed Google Earth with the deb package and the --ignore-depend option to dpkg. Awesome, Google Earth is installed and is working great! Now, however, Update Manager keeps complaining about a "Partial Upgrade", and apt-get won't let me install any new applications. It wants me to do a fix-broken install, but when I do a simulation of apt-get -f install I get some very bad news, they want to uninstall the Google Earth I just worked so hard to install! $> apt-get -f -s install Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies... Done The following packages will be REMOVED: googleearth 0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded. Remv googleearth [6.0.3.2197+0.7.0-1] TL;DR The --ignore-depends passed to dpkg is not propagating to apt-get, so now I can't install any new applications until I uninstall Google Earth, because of it's missing dependencies (even though it works fine without them). How can I fix this?

White box testing with Google Test

- by Daemin

I've been trying out using GoogleTest for my C++ hobby project, and I need to test the internals of a component (hence white box testing). At my previous work we just made the test classes friends of the class being tested. But with Google Test that doesn't work as each test is given its own unique class, derived from the fixture class if specified, and friend-ness doesn't transfer to derived classes. Initially I created a test proxy class that is friends with the tested class. It contains a pointer to an instance of the tested class and provides methods for the required, but hidden, members. This worked for a simple class, but now I'm up to testing a tree class with an internal private node class, of which I need to access and mess with. I'm just wondering if anyone using the GoogleTest library has done any white box testing and if they have any hints or helpful constructs that would make this easier. Ok, I've found the FRIEND_TEST macro defined in the documentation, as well as some hints on how to test private code in the advanced guide. But apart from having a huge amount of friend declerations (i.e. one FRIEND_TEST for each test), is there an easier idion to use, or should I abandon using GoogleTest and move to a different test framework?

Reinstalled Ubuntu 12.04 and now I cannot change preferences like theme, wallpaper, and nautilus preferences

- by krishnab

So I just down-rev'd ubuntu from 13.04 back to 12.04 LTS desktop 64 (Precise). I am using Unity. I just reformatted the Ubuntu partition, but kept my home directory intact, and everything seemed to reconnect just fine. No data was lost. However, I found that I cannot seem to change my preferences. So I cannot seem to change my desktop background, no matter how many ways I try--Ubuntu Tweak, Gnome Tweak, system settings. I also cannot change the system GTK+ theme, though apparently I am able to change the windows border theme. Further, I cannot seem to change my Nautilus preferences--so I cannot seem the make the default view a list view, and I cannot make the "single-click" behavior the default. I even went into the nautilus org.gnome.nautilus settings to manually change things, but no luck. I thought it was a permissions issue, so I did a chown on the home folder and on the .gvfs folder. Still no luck. So somewhere there seems to be a permission that I am not catching. Does anyone have any suggestions? Thanks.

Which algorithms/data structures should I "recognize" and know by name?

- by Earlz

I'd like to consider myself a fairly experienced programmer. I've been programming for over 5 years now. My weak point though is terminology. I'm self-taught, so while I know how to program, I don't know some of the more formal aspects of computer science. So, what are practical algorithms/data structures that I could recognize and know by name? Note, I'm not asking for a book recommendation about implementing algorithms. I don't care about implementing them, I just want to be able to recognize when an algorithm/data structure would be a good solution to a problem. I'm asking more for a list of algorithms/data structures that I should "recognize". For instance, I know the solution to a problem like this: You manage a set of lockers labeled 0-999. People come to you to rent the locker and then come back to return the locker key. How would you build a piece of software to manage knowing which lockers are free and which are in used? The solution, would be a queue or stack. What I'm looking for are things like "in what situation should a B-Tree be used -- What search algorithm should be used here" etc. And maybe a quick introduction of how the more complex(but commonly used) data structures/algorithms work. I tried looking at Wikipedia's list of data structures and algorithms but I think that's a bit overkill. So I'm looking more for what are the essential things I should recognize?

Turn off Windows Defender on your builds

- by george_v_reilly

I've spent some time this evening profiling a Python application on Windows, trying to find out why it was so much slower than on Mac or Linux. The application is an in-house build tool which reads a number of config files, then writes some output files. Using the RunSnakeRun Python profile viewer on Windows, two things immediately leapt out at me: we were running os.stat a lot and file.close was really expensive. A quick test convinced me that we were stat-ing the same files over and over. It was a combination of explicit checks and implicit code, like os.walk calling os.path.isdir. I wrote a little cache that memoizes the results, which brought the cost of the os.stats down from 1.5 seconds to 0.6. Figuring out why closing files was so expensive was harder. I was writing 77 files, totaling just over 1MB, and it was taking 3.5 seconds. It turned out that it wasn't the UTF-8 codec or newline translation. It was simply that closing those files took far longer than it should have. I decided to try a different profiler, hoping to learn more. I downloaded the Windows Performance Toolkit. I recorded a couple of traces of my application running, then I looked at them in the Windows Performance Analyzer, whereupon I saw that in each case, the CPU spike of my app was followed by a CPU spike in MsMpEng.exe. What's MsMpEng.exe? It's Microsoft's antimalware engine, at the heart of Windows Defender. I added my build tree to the list of excluded locations, and my runtime halved. The 3.5 seconds of file closing dropped to 60 milliseconds, a 98% reduction. The moral of this story is: don't let your virus checker run on your builds.

To my lola

Originally posted on: http://geekswithblogs.net/Erik/archive/2013/06/29/153290.aspx I've been staring at the computer for a few minutes now and I honestly don't know what to write. First I thought of writing about myself, where I was born, where I studied, where I am now... but that seems shallow. Now that I thought about it. I'd rather not talk about who I am because it seems irrelevant right now. What I really want to say is..I'm sad. Been like this for quite some time now.Nobody knows I'm sad.I tried telling my wife but I guess she didn't think it was serious. We were having a fight when I told her so she probably thought I was just making up an excuse for my behavior. And besides, she's not the kind of person who'd put my interests before hers especially when she's got lots of things on her mind.I'm not sad every single day. Some days I'm perfectly fine. I actually have no idea when I'd feel sad. It just happens. I'd wake up cheerful and then before I go to bed I already feel depressed. I have no idea what triggers it. On the bed, I'd turn my back to my wife, curl up into a fetal position and start sobbing silently. Awful. Maybe you're wondering now what's the cause of all this.My grandma passed away and I haven't completely come to terms with that fact. I long to see her, talk to her and hold her... but I can't do that anymore because she's gone. I will never be able to hear her voice and feel her touch again. To make matters worse, the only person whom I wish would stay beside me whenever I'm feeling miserable and dejected is never around. She's either working late or out with her friends. Such is my life at the moment. I doubt it will improve anytime soon.

Can't install Apache 2.2.22 on Ubuntu 13.10

My work environment requires Apache 2.2.22 instead of the latest version of 2.4. My machine is currently running Ubuntu 13.10. When I use Synaptic or apt-get it will not allow me to choose an older version of Apache than 2.4. So my question is, how can I force an install of Apache 2.2.22 on Ubuntu 13.10 using Synaptic or apt-get.

Loading the Cache from the Business Application Server

- by ACShorten

By default, the Web Application server will directly connect to the Database to load its cache at startup time. Customers, who implement the product installation in distributed mode, where the Web Application Server and Business Application Server are deployed separately, may wish to prevent the Web Application Server to connect to the database directly. Installation of the product in distributed mode was introduced in Oracle Utilities Application Framework V2.2. In the Advanced Web Application Server configuration, it is possible to set the Create Simple Web Application Context (WEBAPPCONTEXT) to true to force the Web Application Server to load its cache via the Business Application rather than direct loading. The value of false will retain the default behavior of allowing the Web Application Server to connect directly to the database at startup time to load the cache. The value of true will load the cache data via direct calls to the Business Application Server, which can cause a slight delay in the startup process to cater for the architecture load rather than the direct load. The impact of the settings is illustrated in the figure below: When setting this value to true, the following properties files should be manually removed prior to executing the product: $SPLEBASE/etc/conf/root/WEB-INF/classes/hibernate.properties $SPLEBASE/splapp/applications/root/WEB-INF/classes/hibernate.properties Note: For customers who are using a local installation, where the Web Application Server and Business Application Server are combined in the deployed server, it is recommended to set this parameter to false, the default, unless otherwise required. This facility is available for Oracle Utilities Application Framework V4.1 in Group Fix 3 (via Patch 11900153) and Patch 13538242 available from My Oracle Support.

unity, seeing all instances of same open application windows on all virtual desktop

- by Nasser M. Abbasi

I noticed this strange issue with unity. I am using 12.04. The desktop has 4 virtual desktops, which I can switch between using the 'workspace switcher' which is very nice. But I noticed the following: When I have 2 instances of the same app (say 2 different firefox windows, or 2 different terminal windows), in 2 different virtual desktops, then I click on the icon for that application located on the launcher panel (the left long strip with icons on it), then I see the application comes into focus. Then when I click again right away (on the same icon on the launcher), then now all instances of this application that are open come into ONE view (may be on was on desktop 1, and the other was on desktop 3 for example) and then I can now click on the one instance window that I want to select to use. This is all very nice actually. But this does NOT work for all applications! I just tried it, and it worked for firefox, and for gedit and for the gnome terminal. I have one firefox window open in virtual desktop 1, and another window open in virtual desktop 2. I clicked once on the firefox icon, then again, and both windows came into the main desktop and I was able to select which one to use. When I tried the same thing on dolphin file manager, which I also had 2 windows (instances) of it open in 2 different virtual desktops, this behavior did not happen. I clicked again, and nothing happened. Only one remained in focus. So I had to fo look for the second dolphin window the hard way. It looks like some apps are supported by this feature and some are not. How does one make it so that all applications are supported like this? This is a very handy feature. Is it a configuration item somewhere? thanks

sending php mail from localhost

- by SimplySimon

I have installed php, mySQL, postfix and sendmail and have set up a simple email script on my local host server. mail() returns 1 (TRUE) when I send an e-mail, however the email does not arrive at the destination. Installation The mail functions are part of the PHP core. There is no installation needed to use these functions. Requirements For the mail functions to be available, PHP requires an installed and working email system. The program to be used is defined by the configuration settings in the php.ini file. Runtime Configuration The behavior of the mail functions is affected by settings in the php.ini file. Mail configuration options: Name Default Description Changeable sendmail_path NULL Unix systems only: Specifies where the sendmail program can be found (usually /usr/sbin/sendmail or /usr/lib/sendmail) PHP_INI_SYSTEM I found it at /usr/lib/sendmail however, I can not find the configuration file, which is where I assume my problem is, as I have not told anything which server I am using to send my mail through. If anyone can help me I would be grateful.

Commands don't have permission when using absolute path

- by Markos

I have folders set up this way: /srv/samba/video getfacl /srv/samba/video # file: srv/samba/video # owner: root # group: nogroup user::rwx group::--- group:sambaclients:rwx group:deluge:rwx mask::rwx other::--- default:user::rwx default:group::--- default:group:sambaclients:rwx default:group:deluge:rwx default:mask::rwx default:other::--- That means, user deluge has rwx to folder /srv/samba/video. However, when running command as user deluge, I am getting weird permission errors. When in folder /srv/samba/video: sudo -u deluge mkdir foo works flawlessly. But when using absolute path: sudo -u deluge mkdir /srv/samba/video/foo I am getting permission denied. When running sudo -u deluge id, I get output uid=113(deluge) gid=124(deluge) skupiny=124(deluge) which shows that user deluge is indeed in group deluge. Also, the behavior was the same when I gave the permissions also to user deluge not just group deluge. When executing as non-system user, it does work. The reason that I want to use absolute paths is that I am using automatically triggered post-download script which extracts some files into the folder. I have spent way too many hours to solve this problem myself. mkdir isn't the only command that fails, touch is doing the same thing, so I suspect that it's not mkdir's fault. If you need more info, I will try to put it in here, just ask. Thanx in advance. Edit: It seems that the root of the problem is acl set on perent folder /srv/samba, which indeed does not grant permissions to deluge (but neither denies it). getfacl /srv/samba # file: srv/samba # owner: root # group: nogroup user::rwx group::--- group:sambaclients:rwx mask::rwx other::--- default:user::rwx default:group::--- default:group:sambaclients:rwx default:mask::rwx default:other::--- If I grant the permission also to this folder, it suddenly starts to work so I believe that the acl on /srv/samba is somehow denying the permissions to deluge. So the question is: how do I set acl to both /srv/samba and /srv/samba/video so that sambaclients have access to whole /srv/samba and subdirectories and deluge has access only to /srv/samba/video and subdirectories?

python Velocity control of the player, why doesn't this work?

- by Dominic Grenier

I have the following code inside a while True loop: if abs(playerx) < MAXSPEED: if moveLeft: playerx -= 1 if moveRight: playerx += 1 if abs(playery) < MAXSPEED: if moveDown: playery += 1 if moveUp: playery -= 1 if moveLeft == False and abs(playerx) > 0: playerx += 1 if moveRight == False and abs(playerx) > 0: playerx -= 1 if moveUp == False and abs(playery) > 0: playery += 1 if moveDown == False and abs(playery) > 0: playery -= 1 player.x += playerx player.y += playery if player.left < 0 or player.right > 1000: player.x -= playerx if player.top < 0 or player.bottom > 600: player.y -= playery The intended result is that while an arrow key is pressed, playerx or y increments by one at every loop until it reaches MAXSPEED and stays at MAXSPEED. And that when the player stops pressing that arrow key, his speed decreases. Until it reaches 0. To me, this code explicitly says that... But what actually happens is that playerx or y keeps incrementing regardless of MAXSPEED and continues moving even after the player stops pressing the arrow key. I keep rereading but I'm completely baffled by this weird behavior. Any insights? Thanks.

REST and redirecting the response

- by Duane Gran

I'm developing a RESTful service. Here is a map of the current feature set: POST /api/document/file.jpg (creates the resource) GET /api/document/file.jpg (retrieves the resource) DELETE /api/document/file.jpg (removes the resource) So far, it does everything you might expect. I have a particular use case where I need to set up the browser to send a POST request using the multipart/form-data encoding for the document upload but when it is completed I want to redirect them back to the form. I know how to do a redirect, but I'm not certain about how the client and server should negotiate this behavior. Two approaches I'm considering: On the server check for the multipart/form-data encoding and, if present, redirect to the referrer when the request is complete. Add a service URI of /api/document/file.jpg/redirect to redirect to the referrer when the request is complete. I looked into setting an X header (X-myapp-redirect) but you can't tell the browser which headers to use like this. I manage the code for both the client and the server side so I'm flexible on solutions here. Is there a best practice to follow here?
