• Scrolling background with changing textures

  - by Simran kaur

  I have the 2 cubic structures that are my tracks and are scrolling basically to give effect of movement on object. In my OnBecameInvisible() method, I have changed their Tiling using mainTextureScale void OnBecameInvisible() { renderer.material.mainTextureScale = new Vector2(1, numberOfLanes); this.transform.position = new Vector3(this.transform.position.x, this.transform.position.y, 20.0f); } The tiling works fine. But the alternative tracks have their Tiling set to 0 which is giving an undesirable effect. Requirement: I want to be able to set the Tiling of every track that is visible on the screen. How do I do it?

• Deleted files not increasing available free space on Ubuntu (as reported by df -h)

  - by Homunculus Reticulli

  I am writing data munging scripts (python and bash), to munge data and import large quantities of text files into a database. I am currently in the test phase, so I am generating several K's of files and deleting them (the files consume about 20G of space). After a test run, I delete the files (sometimes without having imported into the database). I notice that there is a steady decrease in the amount of free space on my disk (as reported by df -h). I don't understand this, as I use rm * (in the data directory), and in the cases where I use Nautilus, I empty the Trash bin as well. Similarly, I notice that when I import the data into the (postgresql) database, and then delete the data from the tables using DELETE FROM tablename;, the size consumed in the postgresql data directory does not go down either. Currently, I have lost approximately 200G from hard drive, and I need to reclaim that - but don't know what to do to reclaim it - any ideas?. I am running Ubuntu 10.0.4 LTS + postgresql 8.4

• Civilization 4: time in own scenario runs up too quickly.

  - by oKtosiTe

  In Civilization 4 (Beyond the Sword) I started making a scenario that focuses on the colonization of North America. For added realism, I set the StartYear=1780. Everytime I run the scenario, the time runs up far too quickly–probably because I set Era=ERA_ANCIENT and GameTurn=0–so that after just twenty turns the clock nears present day. I'm not really sure how to go fix this, other than by playing an actual marathon game from the start up to the year 1780 and copy over the values. Is there any way to calculate/know the right values for my scenario?

• C# Collision Math Help

  - by user36037

  I am making my own collision detection in MonoGame. I have a PolyLine class That has a property to return the normal of that PolyLine instance. I have a ConvexPolySprite class that has a List LineSegments. I hav a CircleSprite class that has a Center Property and a Radius Property. I am using a static class for the collision detection method. I am testing it on a single line segment. Vector2(200,0) = Vector2(300, 200) The problem is it detects the collision anywhere along the path of line out into space. I cannot figure out why. Thanks in advance; public class PolyLine { //--------------------------------------------------------------------------------------------------------------------------- // Class Properties /// <summary> /// Property for the upper left-hand corner of the owner of this instance /// </summary> public Vector2 ParentPosition { get; set; } /// <summary> /// Relative start point of the line segment /// </summary> public Vector2 RelativeStartPoint { get; set; } /// <summary> /// Relative end point of the line segment /// </summary> public Vector2 RelativeEndPoint { get; set; } /// <summary> /// Property that gets the absolute position of the starting point of the line segment /// </summary> public Vector2 AbsoluteStartPoint { get { return ParentPosition + RelativeStartPoint; } }//end of AbsoluteStartPoint /// <summary> /// Gets the absolute position of the end point of the line segment /// </summary> public Vector2 AbsoluteEndPoint { get { return ParentPosition + RelativeEndPoint; } }//end of AbsoluteEndPoint public Vector2 NormalizedLeftNormal { get { Vector2 P = AbsoluteEndPoint - AbsoluteStartPoint; P.Normalize(); float x = P.X; float y = P.Y; return new Vector2(-y, x); } }//end of NormalizedLeftNormal //--------------------------------------------------------------------------------------------------------------------------- // Class Constructors /// <summary> /// Sole ctor /// </summary> /// <param name="parentPosition"></param> /// <param name="relStart"></param> /// <param name="relEnd"></param> public PolyLine(Vector2 parentPosition, Vector2 relStart, Vector2 relEnd) { ParentPosition = parentPosition; RelativeEndPoint = relEnd; RelativeStartPoint = relStart; }//end of ctor }//end of PolyLine class public static bool Collided(CircleSprite circle, ConvexPolygonSprite poly) { var distance = Vector2.Dot(circle.Position - poly.LineSegments[0].AbsoluteEndPoint, poly.LineSegments[0].NormalizedLeftNormal) + circle.Radius; if (distance <= 0) { return false; } else { return true; } }//end of collided

• How can I get Gnome3 to remember my session?

  - by user60381

  I am running Gnome3, but I had the same problem with Unity, on Ubuntu 12.04. I have a fairly elaborate setup I enjoy using day-to-day. A LibreOffice spreadsheet with everyone's extension numbers; a window with reference data I use regularly; two mulit-tabbed Konsole/Terminal windows with several remote systems sessions, firefox with a set of open tabs, and so on. But whenever I log out, when I return, I must set up everything from scratch. I remember the good 'ol days, when I rebooted, I'd re-log in, and all my windows came back up in the same places as they were when I logged out, and my Konsole/Term would come up with the same remote logins as before.... I'd have to re -setup some of my programs, but that's better than having to move every win into place, and resize them, etc. How do I get this functionality back?

• Samba user does not have folder read permission

  - by user289455

  I have set up a special user for read only samba shares. I set him up in Samba and as a system user. I shared a couple of folders but that user cannot access them. I know samba is working because I also shared them with the main user of the system which is an admin account and it works fine. How can I allow this user to have read permissions on all the directories I want to share without changing anything for any other users of the system? For example, I don't want to give him ownership of any of the files/directories. Just ongoing recursive read access. ongoing recursive is important. If someone adds a file or directory, I still want him to automatically be able to read it.

• Wordpress does not create directories?

  - by Marcappuccino

  First I will just tell you how my wordpress hierarchy looks like: /var/www has all of the wordpress files, which is different from how it is normally set up as /var/www/wordpress (symlinked to /usr/share/wordpress). So var/www contains all of the files that /usr/share/wordpress would have, and /usr/share/wordpress is symlinked to /var/www, with an extra /var/www/wordpress symlinked to /var/www to prevent possible compatibility issues. When uploading a file like a favicon or a .zip-ped theme, everything works fine, and when checking if the theme/favicon is uploaded, wordpress shows that it is, and points to a directory that it thinks that it had created, like http:/localhost/wp-content/uploads/2012/..., which it had not, because the uploads folder is empty! And so there is a broken link on the internet and the theme is displayed but it has just plain text (because it had reverted to a plain theme I think) Please help! I am sorry for such a long post but this is really quite a troublesome problem. I have chowned /var/www and /usr/share/wordpress to www-data.

• Can't open Minecraft with java

  - by Shingaling

  I know this has been asked here before, but none of the solutions have worked for me. I have a fresh install of Ubuntu 12.04 on my system and I installed Open Java 7 and I downloaded Minecraft. I right clicked Minecraft went to properties and set it as an executable and then went to open with and Java is no where to be found in the list. I made a new Java desktop file in /usr/share/applications and now when I go to the list Java is there and I set Minecraft to open with it by default but when I open it nothing at all happens. Now how am I supposed to get Minecraft to work?

• Trust External Surround Soundcard SC-5500p not working

  - by Ederico

  I got the following external sound card to make some awesome noise with my speaker set. It should be plug and play, but it so happens that when I plug it in and hook everything up, there's no sound at all. The speaker set I have works if I plug it in the laptop directly (or rather, if I plug the front speakers cable as I can't plug anything else). http://www.trust.com/products/product.aspx?artnr=14134 Would anyone know how I can workaround this problem and make full use of this external sound card on my Ubuntu 12.04 system?

• How to automatically mount a Windows shared folder on every boot up?

  - by Zabba

  I am able to access Windows' shared folder from Ubuntu 10.10 Nautilus like so: Type into the Location Bar : smb://box/projects Now, I can see the folder in Nautilus, create/read files in it. Also, on desktop I get a folder called "projects on box". But, that folder on the desktop goes away when I reboot. So, I thought that I can automount the Windows' shared projects folder by adding this to my fstab: //box/Projects /home/base/Projects smbfs rw,user,username=jack,password=www222,fmask=666,dmask=777 0 0 (base is my user name on Ubuntu) Now, I get a folder called "Projects" in my home folder after boot up, but it is empty (cannot see the same files that I can see in Nautilus). What's am I doing wrong? Some more detail: This is what I see of the Projects folder when I do ls -l in my home folder: ... drwxr-xr-x 2 root root 4096 2011-01-01 10:22 Projects drwxr-xr-x 2 base base 4096 2011-01-01 09:06 Public ... Note the two "roots". Is that somehow the problem?

• What command are my volume keys running?

  - by user2787904

  In Unity I use my ThinkPad hot keys to change the volume. I need to know the command that these keys run so that I can bind it in my window manager. I have tried using amixer but could not change the volume through command line amixer set Master 10%- amixer: Unable to find simple control 'Master',0 amixer scontrols: Simple mixer control 'IEC958',0 amixer set 'IEC958' 50%- amixer: Invalid command! So obviously this is not what Unity is running. I have tried changing the default sound card as well but that didn't help.

• 12.04 hangs on shutdown/reboot

  - by Wharf Rat

  I'm having the same problem noted here, and when I tried the first fix I found that my /etc/default/grub was empty. I'm willing to try this solution, but I don't know how to remove those drivers. In addition, I'd like my graphics card to be running at optimum efficiency. For now, sudo reboot and sudo shutdown -h nowseem to be working (others have reported that they may only work temporarily), but I don't wish to open a terminal and type my password every time I want to turn my laptop off. What to do?

• BleachBit: How to Completely Clear URL History in Firefox?

  - by tSquirrel

  14.04 / Firefox 29.0 I've been using Bleachbit to clear usage/file history, and for the most part it works great. However, it doesn't seem to clear the website hostnames out of the URL, at all. These addresses are not bookmarked. Also, the total URL isn't preserved, just the hostname. Visit site http://www.bluesnews.com/some_random_URL_string Exit Firefox Run Bleachbit, with ALL Firefox options selected Restart Firefox Check history: completely empty, other than bookmarked sites. www.bluesnews is NOT bookmarked Type "blue" which is Firefox automatically completes as "http://www.bluesnews.com/" Alternate Step #3: Use Firefox's built-in "Clear History" and select ALL entries with a time frame of "Everything". Same result as above. My inquiry in BB forums hasn't been responded to. I found Dan's proposed solution, however changing autocomplete in about:config only turns off the function, it doesn't actually stop storing URLs.

• How to pass information across domains to ask for newsletter only once?

  - by Michal Stefanow

  Lets assume following scenario, I have two sites: example1.com example2.com When user visits 1 there is a prompt "please signup to a newsletter". Same thing happens when user visits 2. However when navigating from 1 to 2 I don't want signup form to be shown. My first thought were 3rd-party cookies, but it seems that they are blocked / not working: http://stackoverflow.com/questions/4701922/how-does-facebook-set-cross-domain-cookies-for-iframes-on-canvas-pages?rq=1 http://stackoverflow.com/questions/172223/how-do-i-set-cookies-from-outside-domains-inside-iframes-in-safari?rq=1 Another thought is to append #noshow for each URL but that would require some work - for instance a script that would intercept click / tap events and modify URL structure depending on the address. (but that seems hacky) I wonder if you know a robust well-established solution to this issue? Thanks

• Processing a stream. Must layers be violated?

  - by Lord Tydus

  Theoretical situation: One trillion foobars are stored in a text file (no fancy databases). Each foobar must have some business logic executed on it. A set of 1 trillion will not fit in memory so the data layer cannot return a big set to the business layer. Instead they are to be streamed in 1 foobar at a time, and have business logic execute on 1 foobar at a time. The stream must be closed when finished. In order for the stream to be closed the business layer must close the stream (a data operation detail), thus violating the separation of concerns. Is it possible to incrementally process data without violating layers?

• Is there a way to forward emails associated with a domain without a mail server?

  - by MeltingDog

  A client owns example1.com but wants to also purchase example2.com and have it point to their original site at example1.com. No problem there. But they also want any emails going to example2.com to be forwarded to their counter parts at example1.com Eg: if someone emails [email protected] it will be forwarded to [email protected] They only way I can think of doing this at the moment is to set up host for example2.com and then set up mail forwarders in cpanel. But this seems a bit excessive and costly. Does anyone know another, cheaper way of doing this?

• Is this a pattern? Should it be?

  - by Arkadiy

  The following is more of a statement than a question - it describes something that may be a pattern. The question is: is this a known pattern? Or, if it's not, should it be? I've had a situation where I had to iterate over two dissimilar multi-layer data structures and copy information from one to the other. Depending on particular use case, I had around eight different kinds of layers, combined in about eight different combinations: A-B-C B-C A-C D-E A-D-E and so on After a few unsuccessful attempts to factor out the repetition of per-layer iteration code, I realized that the key difficulty in this refactoring was the fact that the bottom level needed access to data gathered at higher levels. To explicitly accommodate this requirement, I introduced IterationContext class with a number of get() and set() methods for accumulating the necessary information. In the end, I had the following class structure: class Iterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const = 0; }; class RecursingIterator : public Iterator { RecursingIterator(const Iterator &below); }; class IterateOverA : public RecursingIterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // Iterate over members in dataStructure1 // locate corresponding item in dataStructure2 (passed via context) // and set it in the context // invoke the sub-iterator }; class IterateOverB : public RecursingIterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // iterate over members dataStructure2 (form context) // set dataStructure2's item in the context // locate corresponding item in dataStructure2 (passed via context) // invoke the sub-iterator }; void main() { class FinalCopy : public Iterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // copy data from structure 1 to structure 2 in the context, // using some data from higher levels as needed } } IterationContext ctx(dateStructure2); IterateOverA(IterateOverB(FinalCopy())).iterate(dataStructure1, ctx); } It so happens that dataStructure1 is a uniform data structure, similar to XML DOM in that respect, while dataStructure2 is a legacy data structure made of various structs and arrays. This allows me to pass dataStructure1 outside of the context for convenience. In general, either side of the iteration or both sides may be passed via context, as convenient. The key situation points are: complicated code that needs to be invoked in "layers", with multiple combinations of layer types possible at the bottom layer, the information from top layers needs to be visible. The key implementation points are: use of context class to access the data from all levels of iteration complicated iteration code encapsulated in implementation of pure virtual function two interfaces - one aware of underlying iterator, one not aware of it. use of const & to simplify the usage syntax.

• SSRS optional parameters settings

  - by Natasa Gavrilovic

  Recently I had to create couple SQL Server Reports (SSRS) with optional parameters built in. It took me a while to refresh memory how this can be done. It was very simple to create reports and processes behind, but connecting these two were are little bit challenging – stored procedure was tested and worked fine, but when the report was passing optional parameters it didn’t returned expected results. After tweaking SQL stored procedures and reports parameter options, the following approach turn to be the winning one. 1) Defining report parameters: From Menu bar select ‘View’ and ‘Report Data’ Newly open window should have ‘Parameters’ folder display Right click on this folder and select ‘Add new parameter...’                             Default values need to be added from a query                 A query values need to include ‘’ (empty string) – as highlighted                   2) SQL stored procedure should have CASE statements inside WHERE and it was the only way that a report was getting correct results back.

• How to build completely modular web applications

  - by Webnet

  In the coming months we're going to begin a project where we take a system we've built for a client (v1) and rebuild it from scratch. Our goal with v2 is to make it modular, so that this specific client will have their own set of modules they use, then another client may use a different set of modules altogether. The trick here is that Company A might have a series of checkout and user modules that change how that system works. Company B might stick with the standard checkout procedure but customize how products are browsed. What are some good approaches to application architecture when you're building an application from scratch that you want to have a Core that's shared among all clients while still maintaining the flexability for anything to be modified specifically for a client? I've seen CodeIgniter's hooks and don't think that's a good solution as we could end up with 250 hooks and it's still not flexible enough. What are some other solutions? Ideally we won't need to draw a line in the sand.

• EF Doesn't Like Same Named Tables

  - by Anthony Trudeau

  Originally posted on: http://geekswithblogs.net/tonyt/archive/2013/07/02/153327.aspxIt's another week and another restriction imposed by the Entity Framework (EF). Don't get me wrong. I like EF, but I don't like how it restricts you in different ways. At this point you may be asking yourself the question: how can you have more than one table with the same name?The answer is to have tables in different schemas. I do this to partition the data based on the area of concern. It allows security to be assigned conveniently. A lot of people don't use schemas. I love them. But this article isn't about schemas.In the situation I have two tables:Contact.PersonEmployee.PersonThe first contains the basic, more public information such as the name. The second contains mostly HR specific information. I then mapped these tables to two classes. I stuck to a Table per Class (TPC) mapping, because of problems I've had in the past implementing inheritance with EF. The following code gives you the basic contents of the classes.[Table("Person", Schema = "Employee")]public class Employee {   ...   public int PersonId { get; set; }   [ForeignKey("PersonId")]   public virtual Person Person { get; set; }}[Table("Person", Schema = "Contact")]public class Person {   [Key]   public int Id { get; set; }   ...}This seemingly simple scenario just doesn't work. The problem occurs when you try to add a Person to the DbContext. You get an InvalidOperationException with the following text:The entity types 'Employee' and 'Person' cannot share table 'People' because they are not in the same type hierarchy or do not have a valid one to one foreign key relationship with matching primary keys between them..This is interesting for a couple of reasons. First, there is no People table in my database. Second, I have used the SetInitializer method to stop a database from being created, so it shouldn't be thinking about new tables.The solution to my problem was to change the name of my Employee.Person table. I decided to name it Employee.Employee. It's not ideal, but it gets me past the EF limitation. I hope that this article will help someone else that has the same problem.
