• Which Git-based MIS to track workflow like Trac/Redmine but on console minimastically?

  - by hhh

  Definitions MIS = management information system Some list about console based solutions here and some GUI-hacks here. Been fed up to install all those dependencies and no make -files with GUI -things so which console-based MIS would you suggest for a game-development team with graphical -repo, animation -repo, code -repo, stories -repo, etc ? P.s. I do use Git -submodules and the reason for repo -fragmentation is due to roles and size, certain repos such as graphic -repos tend to be quite large so better to keep them separate. Perhaps useful to readers interested about this http://stackoverflow.com/questions/5881578/trac-vs-redmine https://github.com/jchris/sofa

• Scammers on the lose pretending to be Microsoft

  - by John Paul Cook

  Minutes ago I received a phone call that the caller ID listed as “Out of area”, which I knew was a bad sign. It was difficult to understand the caller because of his very thick accent. He told me that he was from Microsoft and that my computer was throwing a large number of errors and he was calling to help me. He directed me to use Windows R to open a run dialog box, type eventvwr and then look at the Event Viewer. Within Event Viewer, he instructed me to open Custom Views and then open Administrative...(read more)

• when should a database table be broken into multiple tables with relations?

  - by GSto

  I have an application that needs to store client data, and part of that is some data about their employer as well. Assuming that a client can only have one employer, and that the chance of people having identical employer data is slim to none, which schema would make more sense to use? Schema 1 Client Table: ------------------- id int name varchar(255), email varchar(255), address varchar(255), city varchar(255), state char(2), zip varchar(16), employer_name varchar(255), employer_phone varchar(255), employer_address varchar(255), employer_city varchar(255), employer_state char(2), employer_zip varchar(16) **Schema 2** Client Table ------------------ id int name varchar(255), email varchar(255), address varchar(255), city varchar(255), state char(2), zip varchar(16), Employer Table --------------------- id int name varchar(255), phone varchar(255), address varchar(255), city varchar(255), state char(2), zip varchar(16) patient_id int Part of me thinks that since are clearly two different 'objects' in the real world, seperating them out into two different tables makes sense. However, since a client will always have an employer, I'm also not seeing any real benefits to seperating them out, and it would make querying data about clients more complex. Is there any benefit / reason for creating two tables in a situation like this one instead of one?

• Portal View/Projection Matrix near plane

  - by melak47

  For RenderToTexture/Camera based portal rendering, the basics seems simple enough. However, with a free camera, most of the time it is going to be looking at such portals at an angle: Now a regular near clipping plane will not always work here, it will either intersect with the wall the portal is sitting on, or possibly with objects in front of the wall. The desired near clipping plane would be aligned like the portal, producing a view volume more like this: or this in 3D: So here is my question: How does one construct or "truncate" a view/projection matrix to achieve such an off-camera-normal (near) clipping plane?

• ClearTrace Supports SQL Server 2008 R2

  - by Bill Graziano

  It was a long time coming and I hope worth the wait.  If you have SQL Server 2008 R2 installed on the same box as ClearTrace and you download the latest ClearTrace build (36) you’ll be able to read SQL Server 2008 R2 traces.  I also fixed a bug handling very, very large SQL statements.  I encountered an INSERT statement that was 12MB in size.  It was storing XML in a database.  ClearTrace uses regular expressions to clean up the SQL it finds.  Running two dozen regular expressions over this 12MB string caused the application to crash.  In this build I’m just skipping any statement over 1MB.  I’ll do something a little nicer in the next build. (And if you don’t want to download ClearTrace you can test the online version at www.TraceTune.com)

• Threading iPhone

  - by bobobobo

  Say I have a group of large meshes that I have to intersect rays against. Assume also, for whatever reason, I cannot further simplify/reduce poly check count by spatial subdivisioning. I can do this in parallel: bool intersects( list of meshes ) // a mesh is a group of triangles { create n threads foreach mesh in meshes assign to a thread in threads wait until ( threads.run() ) ; // run asynchronously // when they're all done // pull out intersected triangles // from per-thread context data } Can you do this in ios for games? Or is the overhead of thread creation and mutex waiting going to beat-out the benefit of multithreading?

• What Part of Your Project Should be in Source Code Control?

  - by muffinista

  A fellow developer has started work on a new Drupal project, and the sysadmin has suggested that they should only put the sites/default subdirectory in source control, because it "will make updates easily scriptable." Setting aside that somewhat dubious claim, it raises another question -- what files should be under source control? And is there a situation where some large chunk of files should be excluded? My opinion is that the entire tree for the project should be under control, and this would be true for a Drupal project, rails, or anything else. This seems like a no-brainer -- you clearly need versioning for your framework as much as you do for any custom code you write. That said, I would love to get other opinions on this. Are there any arguments for not having everything under control? Is this sysadmin a BOFH?

• OutOfBounds Exception when creating a PolygonShape using jbox2d

  - by B3nGr33ni3r

  So here's the deal, i'm parsing a file that contains the vertices for a polygon, that i want to create in box2d. I create a new PolygonShape() and then call .set() giving it a defined array of Vec, and that defined array's .length property. I expected this to work, since the documentation for jbox2d says this method takes a Vec array, and the count of Vec objects in that array. However, it errors out, and it seems to be unrelated to my code. The error i get is Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 8 at org.jbox2d.collision.shapes.PolygonShape.set(PolygonShape.java:174) and, upon looking at that line in the jbox2d svn repository, i still cannot figure out the issue. Any help is appreciated!

• Retrieve data from an ASP.Net application using ADO.Net 2.0 connected model

  - by nikolaosk

  I have been teaching Entity Framework,LINQ to SQL,LINQ to objects,LINQ to XML for some time now. I am huge fan of LINQ to Entities and I am using Entity Framework as my main data access technology. Entity framework is in the second version right now and I can accomplish most of the things I need. I am sure the guys in the ADO.Net team will implement many more features in the future. I am a strong believer that you cannot really understand the benefits of LINQ to SQL or LINQ to Entities unless you...(read more)

• How do you track Production tasks.

  - by M.C

  I manage a team of coders (5people) that maintain a few modules in a large project. On top of doing coding, we also do production operational tasks (like doing server housekeeping, batch backlog tracking) These tasks are done daily, done by 1 person, and is rotated weekly The problem is this: These tasks are routine, but there I cant think of a practical way of ensuring the person does what he is supposed to do. I thought of using spreadsheets to track, or to the extent of doing a paper checklist, which the person on duty will have to physically sign off. I just want the guy on duty to remember and execute every daily item. What works on your project?

• Several classes need to access the same data, where should the data be declared?

  - by Juicy

  I have a basic 2D tower defense game in C++. Each map is a separate class which inherits from GameState. The map delegates the logic and drawing code to each object in the game and sets data such as the map path. In pseudo-code the logic section might look something like this: update(): for each creep in creeps: creep.update() for each tower in towers: tower.update() for each missile in missiles: missile.update() The objects (creeps, towers and missiles) are stored in vector-of-pointers. The towers must have access to the vector-of-creeps and the vector-of-missiles to create new missiles and identify targets. The question is: where do I declare the vectors? Should they be members of the Map class, and passed as arguments to the tower.update() function? Or declared globally? Or are there other solutions I'm missing entirely?

• Upgrade MySQL to 5.5 on Lucid, upgrade server to Precise or switch to Percona?

  - by xref

  Looking into upgrading mysql on our development server to which is running 10.04 so is stuck at MySQL 5.1, as it appears there is no apt-get support for upgrading to 5.5 except by certain 3rd party PPAs. So I'm looking for which route to take and what other people have done: a) Follow a couple year old guide to manually install MySQL 5.5 and then invest ongoing time into manually downloading and installing security updates every month or two? b) Upgrade 10.04 to 12.04, and from other peoples experience I work with spend several days working out the kinks of that large upgrade, then I'll have access to mysql 5.5 and easy apt-get installation of future security updates? c) Switch from MySQL to Percona Server 5.5 and get all the benefits of that version of mysql, plus easy apt-get updates with their PPA? d) Something else?

• Randomization of biomes

  - by user24527

  You know how in Minecraft, the World is ever-expanding and all the biomes are randomized? My generalized question is: In relation to a space simulation that is also ever-expanding as the player moves about the world, how would one go about programming this randomization in Java? My real question is: Could I get a simplified example broken down into these example classes: astroids (This would include how many astroids there are, their positioning in space, their size, how often the larger astroids occur, how close they are to each other, the limitations of how many of the large asteroids can be in one field, how often astroid fields are generated, etc.) star-types (size, color, type, how often they occur, where hey occur, etc.) inhabitable-planets (size, positioning, how often they're generated, where they are generated, etc.) This would be very helpful currently since I wish to make a simplified version of such a program.

  The first step in migrating to the cloud is the set up phase. This phase includes: 1. Plan Cloud Setup - Create a project plan. 2. Set up infrastructure - The IaaS and PaaS environments need to be installed and configured. This includes databases, network, hardware, disk and application servers. 3. Set up shared components - Are applications, database objects or other components going to be made accessible in the cloud ? These shared components need to be configured and made accessible. 4. Set up self-service portal - Customer self service provisioning, management and monitoring.

• Huge company wants my domain name

  - by Charles Marsh

  Not sure if this is the right place to ask but I'll give it a go. I simply require a little advice; A very large hosted e-commerce platform emailed me a while back and basically asked me to transfer my domain name to them. They made no offer but simply said 'why not change your domain to xx - xx instaead of xxxx' Not they own all the equivalent names in .com, .org all of them apart from my .co.uk I am a registered partner of theirs and my website is a portfolio of all my themes but I also get a lot of enquires through it. I had heard rumors this company is opening an office in the UK! I'm right in thinking I shouldn't just roll over right? I've put some much effort in to SEO and building my reputation... I can't just give it up surly?

• How often do CPUs make calculation errors?

  - by veryfoolish

  In Dijkstra's Notes on Structured Programming he talks a lot about the provability of computer programs as abstract entities. As a corollary, he remarks how testing isn't enough. E.g., he points out the fact that it would be impossible to test a multiplication function f(x,y) = x*y for any large values of x and y across the entire ranges of x and y. My question concerns his misc. remarks on "lousy hardware". I know the essay was written in the 1970s when computer hardware was less reliable, but computers still aren't perfect, so they must make calculation mistakes sometimes. Does anybody know how often this happens or if there are any statistics on this?

• Who created that user?

  - by AaronBertrand

  Twitter has provided some great fodder for blog content lately. And twice this week, I've found an excuse to take advantage of the default trace. Tonight @meltondba asked: I'm trying to find who created a user act in a DB It is true, SQL Server doesn't really keep track of who created objects, such as user accounts in a database. You can get some of this information from the default trace, though, since it tracks EventClass 109 (Audit Add DB User). If you run this code: USE [master] ; GO CREATE LOGIN...(read more)

• 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

• A correct way for JAVA age calculation? [closed]

  - by Jhonnytunes

  I have already a Java calculation of age method. I have a Person Class where I have the method and I need to ask the current time each time the method is called. All I could do is make age a static field of person class, so all person classes use the same time now. Im worring about the Calendar.get() creating Calendar objects every time method is called. Am I doing it wrong? Can I make it better? public short getAge(){ now = Calendar.getInstance(); return (short) ( (now.getTimeInMillis() - birthDate.getTimeInMillis())/ 31536000000L); }

• What is this called?

  - by robertlewis2001

  I'm hoping there's a book or something out there for me to get... If I have a class that has Collection as an instance variable, what is that method of coding called? A design pattern? If so, where can I find more information on it? As I've been working with this mentor, he's really helped me understand my programming weakness and that weakness is thinking in terms of collections or relationships between objects. It just seems so difficult for me right now and I need to read to become smarter. My mentor is a great guy, but he gets frustrated when I start asking lots of questions, so I'm starting to feel like I need to learn more on my own. public class Evaluation { private List<Criterion> criterion = null; public Evaluation() { criterion = new List<Criterion>(); } }

• Box2Dweb very slow on node.js

  - by Peteris

  I'm using Box2Dweb on node.js. I have a rotated box object that I apply an impulse to move around. The timestep is set at 50ms, however, it bumps up to 100ms and even 200ms as soon as I add any more edges or boxes. Here are the edges I would like to use as bounds around the playing area: // Computing the corners var upLeft = new b2Vec2(0, 0), lowLeft = new b2Vec2(0, height), lowRight = new b2Vec2(width, height), upRight = new b2Vec2(width, 0) // Edges bounding the visible game area var edgeFixDef = new b2FixtureDef edgeFixDef.friction = 0.5 edgeFixDef.restitution = 0.2 edgeFixDef.shape = new b2PolygonShape var edgeBodyDef = new b2BodyDef; edgeBodyDef.type = b2Body.b2_staticBody edgeFixDef.shape.SetAsEdge(upLeft, lowLeft) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(lowLeft, lowRight) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(lowRight, upRight) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(upRight, upLeft) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) Can box2d really become this slow for even two bodies or is there some pitfall? It would be very surprising given all the demos which successfully use tens of objects.
