• What are some good questions (and good/bad answers) to ask at an interview to gauge the competency of the company/team?

  - by Wayne M

  I'm already familiar with the Joel Test, but it's been my experience that some of the questions there have the answers "massaged" to make the company seem better than it is. I've had several jobs in the past that, for instance, claimed they had a QA process and did unit testing, and what they really meant is "The programmers test the app, and test with the debugger and via trial-and-error."; they said they used SVN but they just lumped everything into one giant repository and had no concept of branching/merging or anything more complicated than updating and committing; said they can build in one step and what they really mean is it's "one step" to copy dozens of files by hand from the programmer's PC to the live server. How do you go about properly gauging a company's environment to make sure that it's a well-evolved company and not stuck on doing things a certain way because they've done it for years and they're ignorant of change? You can almost never ask to see their source code, so you're stuck trying to figure out if the interviewer's answer is accurate or BS to make the company seem good. Besides the Joel Test what are some other good questions to get the proper feel for a company, and more importantly what are some good and bad answers that could indicate a good or bad company? I mean something like (take at face value, please, it's all I could think of at short notice): Question: How does the software team apply the SOLID principles and Inversion of Control to their code? Good Answer: We adhere to SOLID wherever possible; we use TDD so it kind of forces us to write abstract, testable code. We use Ninject for our IoC container because it's fairly easy to configure - it was that or StructureMap but I find Ninject a bit more intuitive, and who doesn't like ninjas? You're not a pirate, are you? Bad Answer: Our code is pretty secure, yeah. And what's this Inversion of Control thing? I've never heard of it before. You see what I did there. The "good" answer uses facts to back it up and has a bit of "in crowd" humor; the bad answer shows complete ignorance of the question - not necessarily a bad thing if you are interviewing for a manger/director position, but a terrible answer and a huge red flag if you're interviewing as a developer and talking to a senior developer or manager! My biggest problem at the moment is being able to take a generic response and gauge whether it's the good or bad answer; more often than not it's the bad kind and I find myself frustrated almost from day one at the new job. I suppose I could name drop if I ask about specific things (e.g. "Do you write unit tests?" and if the answer is yes, ask if they use NUnit, MbUnit or something else; if they mention data access ask if they use a clean ORM like NHibernate or something more coupled like EF or Linq) but is there another way short of being resolute to actually call the interview on things (which will almost certainly result in not getting the job, but if they are skirting the question it's probably not a job I want).

• Convience of mySQL over xml

  - by Bonechilla

  Currently I use XML to store specific information to correctly load a few things such as a list of specfied characters, scenes and music, Once more I use JAXB in combination with standard compression/decompression(ZIP) functionality to store a list of extrenous data. This data is called to add functionality to the character, somewhat like Skills in an RPG. Each skill is seperated into its own XML file with a grandlist which contains the names of each file with their extensions omitted and zipped in folder that gets encrypted. At first using xml was working fine however as the skill list grow i worry about its stability. I was wondering if I should begin storing the data in mySQL. Originally I planned to simply convert everything to JSON over xml but i think possibly mySQL would be a better move. Can anyone inform me of the key difference and pros and cons of each I guess i'm looking for the best way to store the data more conviently and would be easier to operate on. The data is mostly primatives and strings and the only arraylist of values i have i can just concat into a single field and parse later

• 2D animations frames vs 3D animation for small indie project: timing considerations

  - by mm24

  pretty lame question but was wondering.. I am developing a 2D game using Cocos2D for iOS. The art work till now is all 2D (is a shooter game) but some of the characters would benefit of complex animations (eg. 20 frames). I feel a bit stupid because I came across only now that there is the chance to do 3D to 2D frames exporting and then to use them in Cocos2D. The thing that put me off on 3D gaming at first was that it takes more than one person in a team to do so properly (Illustrator, 3D modeller, 3D animator and programmer). Now I feel a bit stupid because having a 3D model I could do and modify the poses whenever I wanted (I should ask to the 3D animator which I guess would be time expensive). Instead now is me and two illustrators (as I require many frames per character). Is my impression that it would have been much longer right or not? Are there any other project management considerations that can be done on this? Sorry if for some this might be trivial but is my first "indie game developer experience".

• RPi and Java Embedded GPIO: Big Data and Java Technology

  - by hinkmond

  Java Embedded and Big Data go hand-in-hand, especially as demonstrated by prototyping on a Raspberry Pi to show how well the Java Embedded platform can perform on a small embedded device which then becomes the proof-of-concept for industrial controllers, medical equipment, networking gear or any type of sensor-connected device generating large amounts of data. The key is a fast and reliable way to access that data using Java technology. In the previous blog posts you've seen the integration of a static electricity sensor and the Raspberry Pi through the GPIO port, then accessing that data through Java Embedded code. It's important to point out how this works and why it works well with Java code. First, the version of Linux (Debian Wheezy/Raspian) that is found on the RPi has a very convenient way to access the GPIO ports through the use of Linux OS managed file handles. This is key in avoiding terrible and complex coding using register manipulation in C code, or having to program in a less elegant and clumsy procedural scripting language such as python. Instead, using Java Embedded, allows a fast way to access those GPIO ports through those same Linux file handles. Java already has a very easy to program way to access file handles with a high degree of performance that matches direct access of those file handles with the Linux OS. Using the Java API java.io.FileWriter lets us open the same file handles that the Linux OS has for accessing the GPIO ports. Then, by first resetting the ports using the unexport and export file handles, we can initialize them for easy use in a Java app. // Open file handles to GPIO port unexport and export controls FileWriter unexportFile = new FileWriter("/sys/class/gpio/unexport"); FileWriter exportFile = new FileWriter("/sys/class/gpio/export"); ... // Reset the port unexportFile.write(gpioChannel); unexportFile.flush(); // Set the port for use exportFile.write(gpioChannel); exportFile.flush(); Then, another set of file handles can be used by the Java app to control the direction of the GPIO port by writing either "in" or "out" to the direction file handle. // Open file handle to input/output direction control of port FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio" + gpioChannel + "/direction"); // Set port for input directionFile.write("in"); // Or, use "out" for output directionFile.flush(); And, finally, a RandomAccessFile handle can be used with a high degree of performance on par with native C code (only milliseconds to read in data and write out data) with low overhead (unlike python) to manipulate the data going in and out on the GPIO port, while the object-oriented nature of Java programming allows for an easy way to construct complex analytic software around that data access functionality to the external world. RandomAccessFile[] raf = new RandomAccessFile[GpioChannels.length]; ... // Reset file seek pointer to read latest value of GPIO port raf[channum].seek(0); raf[channum].read(inBytes); inLine = new String(inBytes); It's Big Data from sensors and industrial/medical/networking equipment meeting complex analytical software on a small constraint device (like a Linux/ARM RPi) where Java Embedded allows you to shine as an Embedded Device Software Designer.

• What You Can Learn from the NFL Referee Lockout

  - by Christina McKeon

  American football is a lot like religion. The fans are devoted followers that take brand loyalty to a whole new level. These fans that worship their teams each week showed that they are powerful customers whose voice has an impact. Yesterday, these fans proved that their opinion could force the hand of a large and powerful institution. With a three-month NFL referee lockout that seemed like it was nowhere close to resolution, the Green Bay Packers and the Seattle Seahawks competed last Monday night. For those of you that might have been out of the news cycle the past few days, Green Bay lost the game due to a controversial call that many experts and analysts agree should have resulted in Green Bay winning the game. Outrage ensued. The NFL had pulled replacement referees from the high school ranks, and these replacements did not have the knowledge and experience to handle high intensity NFL games. Fans protested about their customer experience. Their anger-filled rants were heard in social media, in the headlines of newspapers, on radio, and on national TV. Suddenly, the NFL was moved to reach an agreement with the referees. That agreement was reached late in the night on Wednesday with many believing that the referees had the upper hand forcing the owners into submission. Some might argue that the referees benefited, not the fans. Since the fans wanted qualified and competent referees, I would say the fans did benefit. The referees are scheduled to return to the field this Sunday, so the fans got what they wanted. What can you learn from this negative customer experience? Customers are in control. NFL owners thought they were controlling this situation with the upper hand over referees. The owners figured out they weren’t in control when their fans reacted negatively. Customers can make or break you more now than ever before, which is why it is more important to connect with them, engage them in a personal manner, and create rewarding relationships. Protect your brand. Whether knowingly or unknowingly, the NFL put their brand and each team’s brand at risk with replacement referees. Think about each business decision you make, and how it may impact your brand at different points in time. A decision that results in a gain today could result in a larger loss down the road. Customer experience matters. The NFL likely foresaw declining revenues in ticket sales, merchandising, advertising, and other areas if the lockout continued. While fans primarily spoke with their minds in the days following the Green Bay debacle, their wallets would be the next things to speak. Customer experience directly affects your success and is one of the few areas where you can differentiate your business. What would you do if your brand got such negative attention? Would you be prepared to navigate such stormy waters? Would you be able to prevent such a fiasco? If you don’t have a good answer to these questions, consider joining us October 3-5, 2012 at the Oracle Customer Experience Summit in San Francisco. You’ll have the opportunity to learn even more about customer experience from industry experts such as best-selling author Seth Godin, Paul Hagen and Kerry Bodine from Forrester Research, Inc., George Kembel from the Stanford d.School, Bruce Temkin of The Temkin Group, and Gene Alvarez from Gartner Inc.. There will also be plenty of your peers and customer experience experts available for networking and discussions.

• MVC and individual elements of the model under a common base class

  - by Stewart

  Admittedly my experience of using the MVC pattern is limited. It might be argued that I don't really separate the V from the C, though I keep the M separate from the VC to the extent I can manage. I'm considering the scenario in which the application's model includes a number of elements that have a common base class. For example, enemy characters in a video game, or shape types in a vector graphics app. The view wants to render these elements. Of course, the different subclasses call for different rendering. The problem is that the elements are part of the model. Rendering them is conceptually part of the view. But how they are to be rendered depends on parameters of both: Attributes and state of the element are parameters of the model User settings are parameters of the view - and to support multiple platforms and/or view modes, different views may be used What's your preferred way of dealing with this? Put the rendering code in the model classes, passing in any view parameters? Put the rendering code in the view, using a switch or similar to select the right rendering for the model element type? Have some intermediate classes as a model-view interface, of which the model will create objects on demand and the view will then render them? Something else?

• Ad-hoc String Manipulation With Visual Studio

  - by Liam McLennan

  Visual studio supports relatively advanced string manipulation via the ‘Quick Replace’ dialog. Today I had a requirement to modify some html, replacing line breaks with unordered list items. For example, I need to convert: Infrastructure<br/> Energy<br/> Industrial development<br/> Urban growth<br/> Water<br/> Food security<br/> to: <li>Infrastructure</li> <li>Energy</li> <li>Industrial development</li> <li>Urban growth</li> <li>Water</li> <li>Food security</li> This cannot be done with a simple search-and-replace but it can be done using the Quick Replace regular expression support. To use regular expressions expand ‘Find Options’, check ‘Use:’ and select ‘Regular Expressions’ Typically, Visual Studio regular expressions use a different syntax to every other regular expression engine. We need to use a capturing group to grab the text of each line so that it can be included in the replacement. The syntax for a capturing group is to replace the part of the expression to be captured with { and }. So my regular expression: {.*}\<br/\> means capture all the characters before <br/>. Note that < and > have to be escaped with \. In the replacement expression we can use \1 to insert the previously captured text. If the search expression had a second capturing group then its text would be available in \2 and so on. Visual Studio’s quick replace feature can be scoped to a selection, the current document, all open documents or every document in the current solution.

• How do you properly organize a commercial game?

  - by Reactorcore

  For the past months I've been studying programming and I've finally learned how to code, but one thing that is confusing me is how to properly organize the design of a game project - code wise. The game I'm building is a pretty standard commercial game. It has the basic components of a normal game: A world, characters and items interacting with each other and all of this is run by game manager. Basically you play as a hero in a world and do stuff. Fight, explore and interact. Think of your standard adventure game that starts off with an intro, goes to the menu system, then gets into the game and back to the menu. Pretty much like 99% of any commercial game or otherwise serious game projects. Thats what I'm aiming at. The problem is: How do you properly code a commercial game architecture? How do you organize it? How do you make it not become unmaintainable spaghetti code? What specific things to keep in mind when building this, codewise? How you can help me: a) Please tell how do you code your own game projects. What is your thought-process when designing the architecture? b) Recommend books, blogs, tutorials, videos or anything else on how to organize a commercial video game. c) Give hints and tips on do's/don'ts when building a game, codewise. Please help!

• Are there plans for handwriting recognition?

  - by Patrick

  This is a big feature when it comes to putting Ubuntu onto tablets. Currently, Netbook edition works great for that purpose and the pen digitiser is perfect, but the handwriting would be a real dealmaker (especially for my business - we could actually move to Linux) to compete with the Windows one. CellWriter exists, but that only handles character and keyboard input (but I don't know about multitouch on the keyboard). It also needs to handle print and cursive, because character mode can be slow and uncomfortable (unless you're writing passwords). Lastly, CellWriter needs to have some default letter shapes rather than having to be trained from the start. There is a software package called MyScript (by Vision Objects) that handles all four modes (keyboard, character, print, cursive) plus calculator and fullscreen, but it's only free as a trial. Still, it would be nice to see it in the For Purchase section and the trial in the free section of the Software Centre. The only other ones are for Chinese/Japanese/Korean characters. What would really make a difference for us is the integration of some formal API with the OS that can automatically activate when running on a tablet to pass ink data to whatever recognition system is installed, and have something available (however rudimentary) to use it.

• Games development with a game loop that's abstracted away

  - by Davy8

  Most game development happens with a main game loop. Are there any good articles/blog posts/discussions about games without a game loop? I imagine they'd mostly be web games, but I'd be interested in hearing otherwise. (As a side note, I think it's really interesting that the concept is almost exclusively used in gaming as far as I'm aware, perhaps that may be another question.) Edit: I realize there's probably a redraw loop somewhere. I guess what I really mean is a loop that is hidden to you. Frames are something you as the developer are not concerned with as you're working on a higher level of abstraction. E.g. someLootItem.moveTo(inventory, someAnimatationType) and that will move from the loot box to your inventory using the specified animation type without the game developer having to worry about the implementation details of that animation. Maybe that's how "real" games end up working, but from reading most tutorials they seem to imply a much more granular level of control is used, but that might just be an artifact of being a tutorial. Edit2: I think most people are misunderstanding what I'm trying to ask, likely because I'm having trouble describing exactly what I'm trying to ask. After some more thinking perhaps what I'm referring to is more along the lines of what I believe is referred to as "scripting" where you're working at a very high level and having some game engine take care of the low level details. For example, take custom maps in Starcraft II or Warcraft III. Many of the "maps" have gameplay that deviates enough from the primary game that they could be considered a separate game written on the same engine. What I'm referring to then is along those lines. I may be wrong because I only dabbed in the Warcraft III editor, but as far as I remember no where in the map editor do you control the game loop, and yet you can create many different games out of it. In my mind, these are games in their own right. If you're playing DotA you don't say you're playing Warcraft III, you say you're playing DotA because that's the actual game you're playing. Such a system may impose limitations that don't exist if you're creating a game from scratch, but it greatly reduces development time because much of the "hard" work has already been done for you. Hopefully that clarifies what I'm asking. Another example of what is I mean, is when you write a web app, of course it communicates through sockets and TCP. But does the average web developer doesn't explicitly write code for connecting sockets. They just need to know about receiving a request and sending a response. There are unique scenarios where you do occasionally need to use raw sockets, but it's generally rare in web development. In a similar fashion, it's very possible to write a game without directly using the game loop, even though one is used behind the scenes. Probably not a AAA title, but there must be hundreds of smaller scale games that can and possibly are written this way. Are there any good resources on writing these "simpler" games?

• What follows after lexical analysis?

  - by madflame991

  I'm working on a toy compiler (for some simple language like PL/0) and I have my lexer up and running. At this point I should start working on building the parse tree, but before I start I was wondering: How much information can one gather from just the string of tokens? Here's what I gathered so far: One can already do syntax highlighting having only the list of tokens. Numbers and operators get coloured accordingly and keywords also. Autoformatting (indenting) should also be possible. How? Specify for each token type how many white spaces or new line characters should follow it. Also when you print tokens modify an alignment variable (when the code printer reads "{" increment the alignment variable by 1, and decrement by 1 for "}". Whenever it starts printing on a new line the code printer will align according to this alignment variable) In languages without nested subroutines one can get a complete list of subroutines and their signature. How? Just read what follows after the "procedure" or "function" keyword until you hit the first ")" (this should work fine in a Pascal language with no nested subroutines) In languages like Pascal you can even determine local variables and their types, as they are declared in a special place (ok, you can't handle initialization as well, but you can parse sequences like: "var a, b, c: integer") Detection of recursive functions may also be possible, or even a graph representation of which subroutine calls who. If one can identify the body of a function then one can also search if there are any mentions of other function's names. Gathering statistics about the code, like number of lines, instructions, subroutines EDIT: I clarified why I think some processes are possible. As I read comments and responses I realise that the answer depends very much on the language that I'm parsing.

• Running multiple box2D world objects on a server

  - by CharbelAbdo

  I'm creating a multiplayer game using LibGdx (with Box2d) and Kryonet. Since this is the first time I work on multiplayer games, I read a bit about server - client implementations, and it turns out that the server should handle important tasks like collision detection, hits, characters dying etc... Based on some articles (like the excellent Gabriel Gambetta Fast paced multiplayer series), I also know that the client should work in parallel to avoid the lag while the server responds to commands. Physics wise, each game will have 2 players, and any projectiles fired. What I'm thinking of doing is the following: Create a physics world on the client When the game is signaled to start, I create the same physics world on the server (without any rendering obviously). Whenever the player issues a command (move or fire), I send the command to the server and immediately start processing it on the client. When the server receives the command, it applies it on the server's world (set velocity etc...) Each 100ms, the server sends the new state to the client which corrects what was calculated locally. Any critical action (hit, death, level up) is calculated only on the server and sent to the client. Essentially, I would have a Box2d World object running on the server for each game in progress, in sync with the worlds running on the clients. The alternative would be to do my own calculations on the server instead of relying on Box2D to do them for me, but I'm trying to avoid that. My question is: Is it wise to have, for example, 1000 instances of the World object running and executing steps on the server? Tomcat used around 750 MBytes of memory when trying it without any object added to the world. Anybody tried that before? If not, is there any alternative? Google did not help me, are there any guidelines to use when you want to have physics on both the client and the server? Thanks for any help.

• How do I create a third Person View using DXUTCamera in DX10?

  - by David

  I am creating a 3d flying game and using DXUTCamera for my view. I can get the camera to take on the characters position, But I would like to view my character in the 3rd person. Here is my code for first person view: //Put the camera on the object. D3DXVECTOR3 viewerPos; D3DXVECTOR3 lookAtThis; D3DXVECTOR3 up ( 5.0f, 1.0f, 0.0f ); D3DXVECTOR3 newUp; D3DXMATRIX matView; //Set the viewer's position to the position of the thing. viewerPos.x = character->x; viewerPos.y = character->y; viewerPos.z = character->z; // Create a new vector for the direction for the viewer to look character->setUpWorldMatrix(); D3DXVECTOR3 newDir, lookAtPoint; D3DXVec3TransformCoord(&newDir, &character->initVecDir, &character->matAllRotations); // set lookatpoint D3DXVec3Normalize(&lookAtPoint, &newDir); lookAtPoint.x += viewerPos.x; lookAtPoint.y += viewerPos.y; lookAtPoint.z += viewerPos.z; g_Camera.SetViewParams(&viewerPos, &lookAtPoint); So does anyone have an ideas how I can move the camera to the third person view? preferably timed so there is a smooth action in the camera movement. (I'm hoping I can just edit this code instead of bringing in another camera class)

• Can't shutdown Ubuntu (Wubi Installation)

  - by zsgre3nd3s7

  I downloaded Ubuntu 12.04 using Wubi. The installation went correctly and everything was working fine until I tried to shutdown. I clicked shutdown and then Ubuntu started shutdown, but as soon as I saw the Ubuntu logo with blank dots under, it froze. I had to perform a hard shutdown. After booting my computer back and going into Ubuntu, I tried shutting it down again but this time it took me on a black page with lots and lots of log writing on the screen and after a little while, it stopped writing stuff. I was able to input characters using the keyboard and everything, but it never shutdown. I had to perform a hard shutdown again. Now it always gives me a Ubuntu logo and freezes. What should I do? I know hard shutdowns are bad and want to avoid them. Is there anyway to make shutdowns work? I tried a reboot and it also froze on the Ubuntu logo. Sony VAIO Model E SVE17115FDB Laptop. Graphic card - AMD RADEON HD 7650M (and it installed correctly in Ubuntu). BIOS - H2O Bios. Processor - Intel i7-3612QM. Edit: I only installed the AMD/ATI proprietary drivers FGLRX, not the AMD/ATI post release drivers because they keep showing an error message. Here is jockey.log. Edit 2: Here is the log that i mentioned before that appeared on my screen, it appeared after i tried reinstalling my AMD driver but failed so i reinstalled the other one. Sorry for the quality i took those pictures with my phone.

• How to tell your boss that his programming style is really bad?

  - by Roflcoptr

  I'm a student and in my spare time I'm working for a big enterprise as Java developer. The job is good, but the problem is, my boss is writing very strange code. I don't want to complain, but some issues are in my opinion really strange. For example: he doesn't know any booleans. All boolean conditions are Strings called "YesOrNo" and then in the condition he uses if (YesOrNo == "Yes") there are a lot of very strange characters in method names and variables like é õ ô or è all loops are infinite loops in the style of for(;;). Then at the end of the loop the condition is tested and if the conditions is fulfilled break; is called. I don't now if I should tell him that I think this isn't a good practice, since he is my boss and decides how and what to do. On the other hand some of this examples are really very weird. Any hints how to cope with? And is this only me who thinks that's bad style?

• Ubiquitous BIP

  - by Tim Dexter

  The last number I heard from Mike and the PM team was that BIP is now embedded in more than 40 oracle products. That's a lot of products to keep track of and to help out with new releases, etc. Its interesting to see how internal Oracle product groups have integrated BIP into their products. Just as you might integrate BIP they have had to make a choice about how to integrate. 1. Library level - BIP is a pure java app and at the bottom of the architecture are a group of java libraries that expose APIs that you can use. they fall into three main areas, data extraction, template processing and formatting and delivery. There are post processing capabilities but those APIs are embedded withing the template processing libraries. Taking this integration route you are going to need to manage templates, data extraction and processing. You'll have your own UI to allow users to control all of this for themselves. Ultimate control but some effort to build and maintain. I have been trawling some of the products during a coffee break. I found a great post on the reporting capabilities provided by BIP in the records management product within WebCenter Content 11g. This integration falls into the first category, content manager looks after the report artifacts itself and provides you the UI to manage and run the reports. 2. Web Service level - further up in the stack is the web service layer. This is sitting on the BI Publisher server as a set of services, runReport and scheduleReport are the main protagonists. However, you can also manage the reports and users (locally managed) on the server and the catalog itself via the services layer.Taking this route, you still need to provide the user interface to choose reports and run them but the creation and management of the reports is all handled by the Publisher server. I have worked with a few customer on this approach. The web services provide the ability to retrieve a list of reports the user can access; then the parameters and LOVs for the selected report and finally a service to submit the report on the server. 3. Embedded BIP server UI- the final level is not so well supported yet. You can currently embed a report and its various levels of surrounding  'chrome' inside another html based application using a URL. Check the docs here. The look and feel can be customized but again, not easy, nor documented. I have messed with running the server pages inside an IFRAME, not bad, but not great. Taking this path should present the least amount of effort on your part to get BIP integrated but there are a few gotchas you need to get around. So a reasonable amount of choices with varying amounts of effort involved. There is another option coming soon for all you ADF developers out there, the ability to drop a BIP report into your application pages. But that's for another post.

• How to solve conflicts with another programmer..

  - by Tio

  Hi all.. I've read this question, but I think it doesn't really applies in my case.. I started to work at new company about 2 months ago with the position of senior web developer, there was already one programmer there, my position is above his, but I'm not his boss.. I don't tell him what to do.. Since the day I started to work at the company, I managed to implement a kind of a test server which he refuses to use, implemented a project management tool which he refuses to use also, and I'm in the process of implementing version control using mercurial ( damn Mercurial that's giving me so much headaches ), which he is going to use.. He is a nice guy, but just the other day we had a big discussion about "best practices", and "coding standards".. for me it's absolutely necessary to have this two things, at the place I'm currently working... otherwise it's not going to work.. This discussion, basically revolved about using short tags and the echo shortcut, and how we shouldn't use it anymore ( because I sometimes use short tags ).. this went for about 15 minutes, until I finally dropped the subject because I had work to do.. and of course he didn't budge even a millimeter, he's continuing to use short tags, and the echo shortcut and he not even cares about what I think.. When I mentioned that we are a team, he told me: "We are not a team, you work on your projects and I work on mine".. Let's just say, that the switch in my brain flipped, I raised my voice, and I told him that he was going nuts.. this was the most improper way to deal it with, I know, but there are certain things that can't be said to me.. The question here, is how do I deal with this? I want, to implement more changes on our work workflow, and I know that it's going to be a pain, with him always complaining and saying things like this.. Our boss is going to intervene in a few days, I talked to him today, the other programmer send him an email the day we had the discussion complaining.. Just to clarify, when I talk about implementing changes, I just don't appear at work, the next day with a sheet of paper, and say: "This is our we are doing things from now on! And there is no discussion.." For example, when I was trying to implement the project management tool, I took the time to talk to everybody that was going to be involved in it, to see what they think about it.. everyone was positive except him, he responded that it was just a mean to control us even more.. Does anyone has any idea on how to deal with this? PS: Truth to be told, I didn't start the best way with him, in the 4º day of work at the company, I found a really bad piece of code on our custom CMS, one of those things that I only expect to find in code produced by a programmer that has only 1 month of training in programming, and I talked to my boss about it... he showed up at the time I saw that piece of code, he saw my face and asked about it, so I told him.. I know the worst thing that can be said to a programmer is saying that their code is awful, but I've already learned that my code isn't the best of the world, so I take criticism in a completely different way now.. maybe he doesn't..

• "previousMode": Controling the Pin Action of a TopComponent

  - by Geertjan

  An excellent thing I learned today is that you, as a developer of a NetBeans module or NetBeans Platform application, can control the pin button. Up until today, whenever I had a TopComponent defined to appear in "rightSlidingSide" mode and then I clicked the "pin" button, as shown here... ...the TopComponent would then find itself pinned in the "explorer" mode. Would make more sense if it would be pinned in the "properties" mode, which is the docked mode closest to the "rightSlidingSide" mode. Not being able to control the "pin" button has been a recurring question (including in my own head) over several years. But the NetBeans Team's window system guru Stan Aubrecht informed me today that a "previousMode" attribute exists in the "tc-ref" file of the TopComponent. Since a few releases, that file is generated via the annotations in the TopComponent. However, "previousMode" is currently not one of the attributes exposed by the @TopComponent.Registration annotation. Therefore, what I did was this: Set "rightSlidingSide" in the "mode" attribute of the @TopComponent.Registration. Build the module. Find the "generated-layer.xml" (in the Files window) and move the layer registration of the TopComponent, including its action and menu item for opening the TopComponent, into my own manual layer within the module. Then remove all the TopComponent annotations from the TopComponent, though you can keep @ConvertAsProperties and @Messages. Then add the "previousMode" attribute, as highlighted below, into my own layer file, i.e., within the tags copied from the "generated-layer.xml": <folder name="Modes"> <folder name="rightSlidingSide"> <file name="ComparatorTopComponent.wstcref"> <![CDATA[<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE tc-ref PUBLIC "-//NetBeans//DTD Top Component in Mode Properties 2.0//EN" "http://www.netbeans.org/dtds/tc-ref2_0.dtd"> <tc-ref version="2.0"> <tc-id id="ComparatorTopComponent"/> <state opened="false"/> <previousMode name="properties" index="0" /> </tc-ref> ]]> </file> </folder> </folder> Now when you run the application and pin the specific TopComponent defined above, i.e., in the above case, named "ComparatorTopComponent", you will find it is pinned into the "properties" mode! That's pretty cool and if you agree, then you're a pretty cool NetBeans Platform developer, and I'd love to find out more about the application/s you're creating on the NetBeans Platform! Meanwhile, I'm going to create an issue for exposing the "previousMode" attribute in the @TopComponent.Registration annotation.

• Strange spam posts not making sense

  - by Paaland

  I'm running a web site with a forum where one small part is open for posting from unregistered users. The site uses captcha, but still some spam posts get through every day. Here is the thing. All of the messages follow the same pattern, but all also come from different IP's. That makes me thing this is some sort of automated scripted "attack" from a botnet of some sorts. The strange thing is that all the messages start with six random characters and contains a couple of links. The words have no meaning and the domains in the links does not even exist. Why would anyone use time and resources spreading these things? Below you can see two of these messages: A5Zfs6 exrzvrbspntz, [url=http://nktqoqllnuab.com/]nktqoqllnuab[/url], [link=http://wtrenldadvsy.com/]wtrenldadvsy[/link], [http://rnlrqfgdvdot.com/] O2oLpL nqeffxhryfdk, [url=http://jutyurbpfxow.com/]jutyurbpfxow[/url], [link=http://jpcdtmdalpow.com/]jpcdtmdalpow[/link], [http://qopqwqxwjdjx.com/] Since all the messages come from different IP's I can't see blocking those will help much. For now I'm considering just dropping all messages following this pattern since it's quite easy to match with a regexp. Have anyone else seen these kinds of messages or know the point of posting them?

This variation is evident in one of the key misunderstandings about the Oracle Database Cloud Service. People could be forgiven for thinking that the Database Cloud Service was a Database-as-a-Service (DBaaS), but this is actually not true. The Database Cloud Service is a Platform-as-a-Service, which presents a different user and developer interface and has a different set of qualities. A good way to think about the difference between these two varieties of Cloud offerings is that you, the customer, have to deal with things at the level of the offering, but not for anything below it. In practice, this means that you do not have to deal with hardware or system software, including installation and maintenance, for DBaaS. You also do not have much control over configuration of these options. For PaaS, you don’t have to deal with hardware, system software, or database software – and also do not have control over these levels in the stack. So you cannot modify configuration parameters for the database with the Database Cloud Service – your interface is through SQL and PL/SQL, with Application Express, included in the Database Cloud Service, or through JDBC for Java apps running in the Java Cloud Service, or through RESTful Web Services. You will notice what is not mentioned there – SQL*Net. You cannot access your Oracle Database Cloud Service by changing an entry in the TNSNames file and using SQL*Net. So the effort involved in migrating an existing Oracle Database in your data center to the Database Cloud Service may be prohibitive. The good news is that Application Express and the RESTful Web Services wizard in the Database Cloud Service allow you to develop new applications very quickly, and, of course, the provisioning of the entire Database Cloud Service takes only minutes.

• Is using the student version of 3DS Max and Unity3d legal?

  - by SubZeron

  I am developing an indie game together with my friend using Unity3D engine. I bought "Silo 3D" for modeling two month ago and for texturing I use 3D coat. We plan to sell our game in the future. For the animations I work with 3DS max (only animation part). My question is, can I work with a students license? The license for the original version is too expensive for me. I am still at the university and I can not buy the 3DS Max license which costs 4000 €. As an alternative I have the choice beetween Blender (can´t work with this software and don't have time to invest for learning a new program) and Truespace (can´t export fbx animation and specially with bones) so for me, 3DS Max is the best choice to be effective and quick. Is it possible to prove it when I export my fbx characters from 3DS Max to Unity3D? I mean can they find out that I have used the students license of 3DS Max for the animations after the release of the game? Maybe with help of DRM? Can I solve that problem when I export the fbx from 3DS Max to Blender and after that export the same fbx to Unity3D?

• RPi and Java Embedded GPIO: Hooking Up Your Wires for Java

  - by hinkmond

  So, you bought your blue jumper wires, your LEDs, your resistors, your breadboard, and your fill of Fry's for the day. How do you hook this cool stuff up to write Java code to blink them LEDs? I'll step you through it. First look at that pinout diagram of the GPIO header that's on your RPi. Find the pins in the corner of your RPi board and make sure to orient it the right way. The upper left corner pin should have the characters "P1" next to it on the board. That pin next to "P1" is your Pin #1 (in the diagram). Then, you can start counting left, right, next row, left, right, next row, left, right, and so on: Pins # 1, 2, next row, 3, 4, next row, 5, 6, and so on. Take one blue jumper wire and connect to Pin # 3 (GPIO0). Connect the other end to a resistor and then the other end of the resistor into the breadboard. Each row of grouped-together holes on a breadboard are connected, so plug in the short-end of a common cathode LED (long-end of a common anode LED) into a hole that is in the same grouping as where the resistor is plugged in. Then, connect the other end of the LED back to Pin # 6 (GND) on the RPi GPIO header. Now you have your first LED connected ready for you to write some Java code to turn it on and off. (As, extra credit you can connect 7 other LEDs the same way to with one lead to Pins # 5, 7, 11, 13, 15, 19 & 21). Whew! That wasn't so bad, was it? Next blog post on this thread will have some Java source code for you to try... Hinkmond

• What is causing these visual artifacts on my OpenGL sprites?

  - by Amplify91

  What could be the cause of the defects in my characters sprite? I am using OpenGL ES 2.0. I draw my sprites in a sprite batch that uses UV coordinates from one large texture atlas. If you look around the character' edges, you'll see two noticeable problems: The invisible alpha background is not invisible, but shows a strange static-like background. There are unwanted streaks where the character nears the edge of the frame (but only in some frames of the animation, this happened to be one of them). Any idea what could be causing these? I will provide related code if asked for, but I'll try to avoid just dumping the entire project and expecting someone to look through it all. EDIT: Here's a bit of code: This is how I generate my UV coordinates: private float[] createFrameUV(int frameWidth, int frameHeight, int x, int y){ float[] uv = new float[4]; if(numberOfFrames>1){ float width = (float)frameWidth / (float)mBitmap.getWidth(); float height = (float)frameHeight / (float)mBitmap.getHeight(); float u = (float)x / (float)mBitmap.getWidth(); float v = (float)y / (float)mBitmap.getHeight(); uv[0] = u; uv[1] = v; uv[2] = u + width; uv[3] = v + height; }else{ uv[0] = 0f; uv[1] = 0f; uv[2] = 1f; uv[3] = 1f; } return uv; } These are some OpenGL settings: GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MIN_FILTER, GLES20.GL_LINEAR); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MAG_FILTER, GLES20.GL_LINEAR); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_WRAP_S, GLES20.GL_CLAMP_TO_EDGE); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_WRAP_T, GLES20.GL_CLAMP_TO_EDGE);
