• How can I change the color of this part of Nautilus for my Ambiance theme modification?

  - by WarriorIng64

  I am currently messing around with Ambiance, trying to give Nautilus a dark sidebar (because I think it looks much better that way, especially with the current look having the dark-colored breadcrumbs clashing horribly with the light-colored sidebar). I have zero experience and knowledge of how to create GTK+ themes, and I couldn't find any documentation online, so I just made a copy of the folder for Ambiance under /usr/share/themes, renamed it "Ambiance Dark Sidebar" and just started messing with color values. As shown below, I found the value in nautilus.css needed to be tweaked to create the dark sidebar, but there is still one part that stubbornly stays light gray that I want to change so it matches the rest better (I'm not sure what the proper terminology is here, so I just provided a picture and marked it in red). Does anyone know what I need to do to change the color of this part so it matches the rest of the sidebar better? I already know from seeing themes like Adwaita Dark that this should be possible, but even after poking around in that I didn't find anything that seemed to help. Here are the contents of the files I modified in the theme folder Ambiance Dark Sidebar, stored alongside Ambiance in /usr/share/themes: index.theme gtk-3.0/apps/nautilus.css

• Dynamic filter expressions in an OpenAccess LINQ query

  We had some support questions recently where our customers had the need to combine multiple smaller predicate expressions with either an OR or an AND  logical operators (these will be the || and && operators if you are using C#). And because the code from the answer that we sent to these customers is very interesting, and can easily be refactorred into something reusable, we decided to write this blog post. The key thing that one must know is that if you want your predicate to be translated by OpenAccess ORM to SQL and executed on the server you must have a LINQ Expression that is not compiled. So, let’s say that you have these smaller predicate expressions: Expression<Func<Customer, bool>> filter1 = c => c.City.StartsWith("S");Expression<Func<Customer, bool>> filter2 = c => c.City.StartsWith("M");Expression<Func<Customer, bool>> filter3 = c => c.ContactTitle == "Owner"; And ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Multiple instances of Intellitrace.exe process

  - by Vincent Grondin

  Not so long ago I was confronted with a very bizarre problem… I was using visual studio 2010 and whenever I opened up the Test Impact view I would suddenly see my pc perf go down drastically…  Investigating this problem, I found out that hundreds of “Intellitrace.exe” processes had been started on my system and I could not close them as they would re-start as soon as I would close one.  That was very weird.  So I knew it had something to do with the Test Impact but how can this feature and Intellitrace.exe going crazy be related?  After a bit of thinking I remembered that a teammate (Etienne Tremblay, ALM MVP) had told me once that he had seen this issue before just after installing a MOCKING FRAMEWORK that uses the .NET Profiler API…  Apparently there’s a conflict between the test impact features of Visual Studio and some mocking products using the .NET profiler API…  Maybe because VS 2010 also uses this feature for Test Impact purposes, I don’t know… Anyways, here’s the fix…  Go to your VS 2010 and click the “Test” menu.  Then go to the “Edit Test Settings” and choose EACH test setting file applying the following actions (normally 2 files being “Local” and TraceAndTestImpact”: -          Select the Data And Diagnostic option on the left -          Make sure that the ASP.NET Client Proxy for Intellitrace and Test Impact option is NOT SELECTED -          Make sure that the Test Impact option is NOT SELECTED -          Save and close   Edit Test Settings   Problem solved…  For me having to choose between the “Test Impact” features and the “Mocking Framework” was a no brainer, bye bye test impact…  I did not investigate much on this subject but I feel there might be a way to have them both working by enabling one after the other in a precise sequence…  Feel free to leave a comment if you know how to make them both work at the same time!   Hope this helps someone out there !

• Cocos2d/Cocos2d-x Attaching an arrow (sprite) to another body sprite (person)

  - by Satchmo Brown

  I am trying to set up a simple bow and arrow game. When the arrow hits the enemy body, the arrow's body is deleted and the arrow sprite continues to update, keeping the position correct in relation to the enemy it hit. Picture an arrow sticking into a body and that body still rotating and moving. My problem is that the rotation is completely wrong when the enemy rotates. I know how to do this in 3d with matrix transformation but I can't seem to figure it out in 2d with Cocos. Here is my method. I save offset at which the arrow hit the enemy. Every frame, I make the rotation of the sprite match the rotation of the enemy. Then, I apply the offset I took initially which is where the arrow hit the enemy. When they rotate, they rotate about their respective anchors and I am wondering if I need to set the anchor of the arrow to the center of the sprite. Does anyone know of an easy way to do this. If not, I will try to create an algorithm where the anchor is set to the offset divided by the width and height of the sprite image hopefully giving me the correct anchor values. Then I assume I need to reposition the sprite. Does anyone have a simpler way to do this?

• What is Mark Shuttleworth's "Easter eggs" blog a reference to? [closed]

  - by fluteflute

  I saw this blog post today, and I was wondering if there's some meaning within the Ubuntu community that I've missed? (I know what an easter egg is in a computer context.) One of our ducks has started dropping eggs in random locations in the garden. I don’t know which duck, but I assume it’s one of the new females we took in from the SPCA, who hasn’t figured out “nesting” yet. I do love ‘em but they’re not African Grey’s in the IQ department. Anyhow, I think I finally understand why people hide eggs in the garden at Easter. Because ducks used to do it for them! I suppose, for millennia, this has been the season to go hunting for eggs. Now we just substitute chocolate ones instead. For the moment, I’ve kept them in a cool shady spot while I keep an eye out for an actual nest. If a polecat doesn’t find them first, I may be able to slip them onto the nest in time for them to get hatched along with some cousins.

• Problem with sound driver

  - by JiminP

  I had problem that sound had lag in Flash. (Other than that, there was no problem.) On the internet, I found that installing OSS4 might help me. So I installed OSS4, but there was some problems (no sound on Flash, and couldn't use function key on the laptop - which is quite annoying), so I try to remove OSS4 and re-installing sound modules. After some mess-up, the whole sound was gone. I used Ubuntu for a year, but I don't know how to use the terminal well (All I know is basic commands like sudo, ls, or apt-get).. Now I'm trying to recover by following instructions at this page, but I have some problems... :( When I try to follow instructions: sudo aplay -l finds no sound drivers. find /lib/modules/'uname -r' | grep snd (backtick changed to ' due to code markup) returns nothing. When I try to do sudo apt-get install linux-restricted-modules-'uname -r' linux-generic, it says that it can't find linux-restricted-modules-3.0.0-13-generic package. lspci -v | grep -A7 -i "audio" returns this, which doesn't contain anything about the name of the driver. Writing sudo modprobe sn and pressing tab twice only returns sudo modprobe sn9c102. sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-'uname -r' linux-ubuntu-modules-'uname -r' libasound2 returns this, and didn't change non of above. sudo apt-get install linux-alsa-driver-modules-$(uname -r) fails because it can't find the package linux-alsa-driver-modules-3.0.0-13-generic. Compiling ALSA driver doesn't work. When I try to make, it says that /lib/modules/3.0.0-13-generic/build/include/linux/modversions.h doesn't exist. I'm using Ubuntu 11.10. Can anyone help me? I can re-install Ubuntu, but I don't want to....

• Automate #include refactoring in C++ [on hold]

  - by Mikhail

  I have a big project with hundreds of files. And as it often happens to C++ projects, #include directives are in messed up. I want to refactor them to increase clarity, decrease compilation time and simplify analysis. For each .h file I want to make sure that: It have #include directives only for types it is using But it have only forward declarations of types that are used as T* or T& For each .cpp file I want to make sure that: It have #include directives only for types it is using and not already included by another headers (no indirect includes when possible) I'm looking for a tool which will help me to automate this refactoring. For now I only know of tools that helps to remove redundant includes, they are many: PC-lint include-what-you-use cppclean ProFactor IncludeManager But I know of no tools to help me to move necessary includes in .h files or replace includes with forward declarations. Any ideas? Tools for Windows and Visual Studio are preferred. Update. Considered to be off-topic. Please, follow the link on Software Recommendations http://softwarerecs.stackexchange.com/q/4461/3331

• Perth's ADF Community Event now an open invite

  - by Chris Muir

  Yesterday saw the next ADF Community Event in Perth, and as promised we grew from 15 to 25 attendees (which is going to cause a bit of a problem soon if we keep growing as we're going to run out of powerpoints for laptops). This bimonthly enjoyed presentations from Matthew Carrigy from the Dept of Finance WA on the ADF UI Shell, a small presentation from me about how Fusion Apps uses ADF, and a hands on based on programatically extending ADF BC to call external web services.  For Matt, his first presentation to a user group, with two live demos, all kudos to him for making it look smooth (for the record I hate live demos, I always break something) - thank you Matt! We've already lined up our speakers for the next event in November, and will be inviting yet more customers to this event.  However the event will now move to an open invite, so if you'd like your staff to attend please let me know by emailing chris DOT muir AT oracle DOT com. Alternatively I've had a fair few requests now for an "Intro to ADF" 1 day session so I'll consider this soon.  Certainly if you're interested let me know as this will help organize the event earlier rather than later.

• C# and Unity - Learning to Develop a game by developing the game I want to develop

  - by 97s

  So I am pretty new to C#, I have some python and javascript experience, but nothing substantial. I have read a lot about C# and Unity and I know they are the tools I want to use. My question is: Should I be reading books about C# or should I just start hacking in unity and piecing the game together part by part? Right now I am going through the book, HeadFirst C#, and it is very good, but I taught myself web design and javascript by just creating and hacking until I got the results I wanted then looked at other code to see ways they did it and improved my code. The issue is that with the browser I got immediate results and it was all under one roof, where developing games is a completely different monster. I am just wondering if my time would be better spent buying a book that uses C# to teach you unity, and doing that instead, or if the time spent in HeadFirst book is going to be valuable. Thanks a ton, I am having difficulties using my time, and I just want to maximize it as I don't have a lot of free time. Edit: Hopefully this isn't to broad? If it is, I will delete and go elsewhere just let me know. Thanks.

• Stuck With grub rescue> console

  - by rej santos

  Here is the background of my issue: I just recently installed the latest version of Ubuntu along side with Windows 8 Enterprise. However upon checking the disk size, it seems that some of the portions of the hd memory were gone so I decided to check the disk partition and have seen that is was being used by another file system. Thinking that the Ubuntu takes it boots stuff from my drive C: , I deleted that partition and formated so I can use it to store some movies, music etc. Now, as I switch on my machine, I am stucked with: error: unknown filesystem grub rescue> I googled a lot and saw the following command which seems no to me like sudo, chainloader etc, all of these command only returns unknown command in the console. What I just wanted is to boot from my Windows 8 OS. Just to add, I can't open the BIOS menu so I could choose what media to boot. As I open my machine it automatically takes me to grub rescue console. Here are the thing I already have: Ubuntu Installation Disk Windows 8 System repair Disk I just don't know how to boot into these things. Let me know what to do.

• apt-get doesnt download files from NFS location

  - by Pravesh

  I have switched to unix from last 3 months and trying to understand install process and in particular apt-get. I am able to successfully install and download the packages when I configure my repository on http location in /etc/apt/sources.list file. e.g. deb http://web.myspqce.com/u/eng/rose/debian-mirror-squeeze-amd64/mirror/ftp.us.debian.org/debian/ squeeze main contrib non-free This command will download(/var/cache/apt/archive) and install the package when i use apt-get install When I change the source location to file instead of http(nfs mount point), the package is getting installed but NOT getting downloaded in /var/cache/apt/archive. deb file:/deb_repository/debian-mirror-squeeze-amd64/mirror/ftp.us.debian.org/debian/ squeeze main contrib non-free Please let me know if there is any configuration or settings that i have to make to let apt-get to both download and install package when i use (nfs)file:/ instead of http:/ in sources.list. To achieve this, I can use apt-get --downlaod-only and then use apt-get install for both download and install in two separate calls, but I want to know why package is not getting downloaded with apt-get install but only getting installed when used with file:/ in sources.list

• Diablo 3 "freezes" periodically

  - by Shauna

  I'm running Diablo 3 (start edition, digital download) on the following: Ubuntu 12.04 64-bit (stock Unity, Gnome, etc; kernel version 3.2.0-29-generic) Wine version 1.5.11 (base, from Wine's PPA, game started with setarch i386 -3) Intel i7 920 CPU nVidia GTX260 with driver version 295.49 ("post-release updates" entry within the proprietary drivers tool), dual monitors 6GB RAM Every so often (and what appears to be at random), the game video will freeze up. I can still move the mouse, and it reacts to ctrl+alt+f2 to drop into text mode, but I can't get back to the desktop (which means I can check terminal to see what's going on after launching from terminal, especially since even in windowed mode, the secondary screen gets shut off by the game), and I can't continue to play the game. In order to get it running again, I have to restart lightdm, then relaunch the game (or, in a couple of rare cases, I had to restart the computer entirely, because running sudo service lightdmn [stop/start] doesn't appear to react). Turning down the video settings seems to have helped in some cases, but not all of them. Times it's frozen on me: The beginning of The Fallen Start quest part 6 - kill the Wretched Mother, right as you walk out of New Tristram and engage in the monsters on the northern path (repeatedly froze here until I adjusted the graphics down) Within the cinematic/event upon finding Deckard Cain While fighting the skeletons to protect Deckard Cain When about to enter Leoric's passage after Cain sends you back to where you found him That's as far as I've gotten through the game so far. Additionally, this doesn't happen on other games I play and seems to only occur with Diablo 3. Has anyone else run into this issue and know a possible cause or fix, or at least know where I can look (and what to look for) to figure out why this is happening?

• Accessing a Web Service: Learning Resource needed

  - by abel

  I have been searching for resources to learn (Java) Web Services. Although I have found a lot of resources and tutorials on JWS, I am confused with the version numbers, the abbreviations and Metro. Plus the last update to Metro was in 2008. Is it a worthwile thing to learn? I wanted to learn how to access Web Services, since an upcoming project is about accessing one. I have some experience with OAuth on Twitter(using code available). Things I know about the project: I have to access a Web Service. Java is the preferred platform to use(Although I know I can use any). Axis can be used to access the Web Service(I have never used Axis) I have a meeting scheduled to learn more, but I sure don't want to look silly since I am no Java expert, have never created or accessed Web Services using Java. My Questions: 1.Can someone point me to a tutorial which will help me learn how to access a already running Web Service (Preferably SOAP(?), not REST. It's XML based) 2. Will you recommend using PHP or Python to do the work of accessing the web service? I am expecting a lot of nay saying, but I hope I get some answers too. I will clarify things if needed.

• What is the best way to check if there is overlap between player and static, non-collidable items in bullet physic engine

  - by tigrou

  I'd like to add non collidable objects (eg: power ups, items, ...) in a game world using Bullet Physics Engine and to know if there is collision between player and them. Some info : there is a lot of items ( 1000), all are box shapes and they don't overlap. Here is things i have tried : btDbvt* bvtItems = new btDbvt(); //btDbvt is a hierachical AABB tree, used by Bullet foreach(var item ...) { btDbvtVolume volume = ... //compute item AABB; bvtItems->insert(volume, (void*)someExtraData); } Then, to find collisions between items and player : playerRigidBody->getAabb(min, max); btDbvtVolume playervolume = ... //compute player AABB bvtItems->collideTV(bvtItems->m_root, playervolume, *someCollisionHandler); This works fairly well (and its very fast), however, there is a problem : it only check items AABB against player AABB. That loss of precision is acceptable for items but not for player which is not a box. It would actually need another check to make sure player really collide with item but i don't know how to do this in Bullet. It would have been nice to have a function like this : playerRigidBody->checkCollisionWithAABB(); After doing trying that, I discovered that a btGhostObject exist and seems to have been made for that. I changed my code like this : foreach(var item...) { btCollisionObject* ghostObject = new btGhostObject(); ghostObject->setCollisionShape(boxShape); ghostObject->setCollisionFlags(ghostObject->getCollisionFlags() | btCollisionObject::CF_NO_CONTACT_RESPONSE); startTransform.setOrigin(...); //item position ghostObject->setWorldTransform(startTransform); dynamicsWorld->addCollisionObject(ghostObject, btBroadphaseProxy::SensorTrigger, btBroadphaseProxy:: CharacterFilter); } It also works ok, but there is a huge fps drop (almost ten times slower) which is not acceptable. Maybe there is something missing (forget set a flag) and Bullet is doing extra job for nothing or maybe all that ghostObjects are polluting broad phase and ghostObject is not the right thing for that. Any help would be appreciated.

• C# vector class - Interpolation design decision

  - by Benjamin

  Currently I'm working on a vector class in C# and now I'm coming to the point, where I've to figure out, how i want to implement the functions for interpolation between two vectors. At first I came up with implementing the functions directly into the vector class... public class Vector3D { public static Vector3D LinearInterpolate(Vector3D vector1, Vector3D vector2, double factor) { ... } public Vector3D LinearInterpolate(Vector3D other, double factor { ... } } (I always offer both: a static method with two vectors as parameters and one non-static, with only one vector as parameter) ...but then I got the idea to use extension methods (defined in a seperate class called "Interpolation" for example), since interpolation isn't really a thing only available for vectors. So this could be another solution: public class Vector3D { ... } public static class Interpolation { public static Vector3D LinearInterpolate(this Vector3D vector, Vector3D other, double factor) { ... } } So here an example how you'd use the different possibilities: { var vec1 = new Vector3D(5, 3, 1); var vec2 = new Vector3D(4, 2, 0); Vector3D vec3; vec3 = vec1.LinearInterpolate(vec2, 0.5); //1 vec3 = Vector3D.LinearInterpolate(vec1, vec2, 0.5); //2 //or with extension-methods vec3 = vec1.LinearInterpolate(vec2, 0.5); //3 (same as 1) vec3 = Interpolation.LinearInterpolation(vec1, vec2, 0.5); //4 } So I really don't know which design is better. Also I don't know if there's an ultimate rule for things like this or if it's just about what someone personally prefers. But I really would like to hear your opinions, what's better (and if possible why ).

• how to choose a web framework and javascript library?

  - by Trylks

  I've been procrastinating learning some framework for web apps w/ some library for AJAX, something like django with prototype, or turbogears with mootools, or zeta components with dojo, grok, jquery, symfony... The point is to spend some of my spare time, have "fun" and create cool stuff that hopefully is some useful. I think maybe I wouldn't like something like GWT or pyjamas because I wouldn't like to "get married" with some technology, I want to keep my freedom to add another javascript library, and so on. I didn't decide even the language yet, but I think I'd prefer python. PHP could be fine if there is some framework that is nice enough. Besides that, I don't even know where to start. I don't feel like learning a framework to then realize there is something that I cannot comfortably do, switch to another framework then find that a third framework has something really cool, etc. And the same goes for javascript libraries. So, some guidance would be really appreciated. I don't really know why are so many options available and what do they aim for, I guess some of them focus on some aspects and some on others, but I just want to make cool and nice apps that I can easily maintain, without spending too much time on coding or learning and avoiding the "trapped in the framework" feeling, when doing something is awfully complicated (or even impossible) with compared with the rest of things or doing that same thing on a different framework. I guess in the end I'll go for django and jquery since they are the most widely used options, afaik, but if I was going for the most widely used options I guess I should choose Java or PHP (I don't really like Java for my spare time, but php is not so bad), so I preferred to ask first. I think the question has to consider both, framework and library, since sometimes they are coupled. I think this is the place to ask this kind of things, sorry if not, and thank you.

• One of my most frequently used commands

  - by Kevin Smith

  On a Linux or UNIX server this is one of my most frequently used commands. find . -name "*.htm" -exec grep -iH "alter session" {} \; It is an easy way to find a string you know is in a group of files, but don't know or can't remember which file it is in. For the example above, I knew that WebCenter Content sends a bunch of alter session commands to the database when it opens a new database connection. I wanted to find where these were defined and what all the alter session commands were. So, I ran these commands: cd /opt/oracle/middleware/Oracle_ECM1/ucm/idc/resources/core find . -name "*.htm" -exec grep -iH "alter session" {} \; And the results were: ./tables/query.htm: ALTER SESSION SET optimizer_mode = ?./tables/query.htm: ALTER SESSION SET NLS_LENGTH_SEMANTICS = ?./tables/query.htm: ALTER SESSION SET NLS_SORT = ?./tables/query.htm: ALTER SESSION SET NLS_COMP = ?./tables/query.htm: ALTER SESSION SET CURSOR_SHARING = ?./tables/query.htm: ALTER SESSION SET EVENTS '30579 trace name context forever, level 2'./tables/query.htm: ALTER SESSION SET NLS_DATE_FORMAT = ?./tables/query.htm: alter session set events '30579 trace name context forever, level 2' I could then go edit the query.htm file and find the include that contained all the ALTER SESSION commands.

• Returning Value of Radio Button Jquery [migrated]

  I am trying to figure out why, when I run this code, I am getting undefined for my correct answers. $(document).ready (function () { // var answers = [["Fee","Fi","Fo"], ["La","Dee","Da"]], questions = ["Fee-ing?", "La-ing?"], corAns = ["Fee", "La"]; var counter = 0; var $facts = $('#main_ .facts_div'), $question = $facts.find('.question'), $ul = $facts.find('ul'), $btn = $('.myBtn'); $btn.on('click', function() { if (counter < questions.length) { $question.text(questions[counter]); var ansstring = $.map(answers[counter], function(value) { return '<li><input type="radio" name="ans" value="0"/>' + value + '</li>'}).join(''); $ul.html(ansstring); var currentAnswers = $('input[name="ans"]:checked').map(function() { return this.val(); }).get(); var correct = 0; if (currentAnswers[counter]==corAns[counter]) { correct++; } } else { $facts.text('You are done with the quiz ' + correct); $(this).hide(); } counter++; }); // }); It is quite long and I'm sorry about that, but I don't really know how tostrip it down. I also realize this isn't the most elegant way to do this, but I just want to know why I can't seem to get my radio values. I will add the markup as well if anyone wants.

• What kind of website or coding is suitable and safe for an artist's website

  - by Dan S

  I have a web design project that is related to a singer, and I used Joomla for my previous project and designed good music websites. But for this project I cannot find a suitable template to edit and use. As the website is so simple and does not have any special functionality, I'm thinking about creating a website with just simple CSS, html and jQuery. I'm Good at them and can make a perfect look but I am not sure about the security. In Joomla I use different security plugins but do not know about a client-side scripting. So generally I need your ideas, about the following questions: - Is Joomla and generally CMS a good option for a music website? - How famous artists' website is base on? CMS or Client-side scripting? - Do you recommend to create it manually without using and CMS or template? - An do you suggest WordPress for this type of websites? (The website will have these pages: Biography, News, Music (with a music player), Photos, videos and contacts). That's it! Thank you for all your responds, I had a look at Joomla and the only template I chose is This One which seems very simple, and I am worry about module position, because it seems does not have any module position at all. I tried to contact the provider but did not get any respond. Does anyone know about its module position, I mean is there any way to find them? An is it possible to create a 2-3 module positions? Also I had a look at ThemeForest's WordPress templates and it has such a great template. I think WordPress is more active in creating artistic templates. But is it secure and professional to use this CMS for a singer who is kinda famous it his country? I am talking about a template like this. Share your opinions guys.

• Procedural world generation oriented on gameplay features

  In large procedural landscape games, the land seems dull, but that's probably because the real world is largely dull, with only limited places where the scenery is dramatic or tactical. Looking at world generation from this point of view, a landscape generator for a game (that is, not for the sake of scenery, but for the sake of gameplay) needs to not follow the rules of landscaping, but instead some rules married to the expectations of the gamer. For example, there could be a choke point / route generator that creates hills ravines, rivers and mountains between cities, rather than the natural way cities arise, scattered on the land based on resources or conditions generated by the mountains and rainfall patterns. Is there any existing work being done like this? Start with cities or population centres and then add in terrain afterwards? The reason I'm asking is that I'd previously pondered taking existing maps from fantasy fiction (my own and others), putting the information into the system as a base point, and then generating a good world to play in from it. This seems covered by existing technology, that is, where the designer puts in all the necessary information such as the city populations, resources, biomes, road networks and rivers, then allows the PCG fill in the gaps. But now I'm wondering if it may be possible to have a content generator generate also the overall design. Generate the cities and population centres, balancing them so that there is a natural seeming need of commerce, then generate the positions and connectivity, then from the type of city produce the list of necessary resources that must be nearby, and only then, maybe given some rules on how to make the journey between cities both believable and interesting, generate the final content including the roads, the choke points, the bridges and tunnels, ferries and the terrain including the biomes and coastline necessary. If this has been done before, I'd like to know, and would like to know what went wrong, and what went right.

• Difference between bug, defect and flaw

  - by Hossein

  I was reading "Software Security: Building Security In" and in the first chapter I faced with 3 terms: bug, defect and flaw. The author gave a definition for each of them but I couldn't completely understand these. Can someone give me some examples for each term? What is a defect and what is a flaw? I think I know what bug is, a bug is a malfunction of a part of system which produces undesirable result, be it crashing on a wrong input or miscalculating a series of computations. Can someone elaborate more and correct me if I am wrong in this? UPDATE To be more precise in the book I mentioned above, they (the words) are presented in a way to make a distinction, that's why I am asking to know more. In that book there are some examples denoting which sample belongs to what and which category. For example: Buffer overflow is said to be a bug and issues in method overriding (subclassing issues) is being related to flaw category. Again race condition handling issues are considered bugs and Error-handling problems (fails open) are told to be flaws! I want more elaboration on these regards.

• Materialized View vs POJO View based on Objects representing Oracle tables

  - by Zack Macomber

  I have about 12 Oracle tables that represent data that's being integrated from an external system into my web application. This data is going to be used in an informational and comparative manner for the clients using my web application. On one particular page of my web application, I need to combine data from 3 - 5 Oracle tables for display as an HTML table on the page. We are NOT currently using a framework (Apache Struts for instance) and we're not in a position to move this Java web application into one at this moment (I'm trying to get us there...). I am certainly not an architect, but I see one of two ways that I can effectively build this page (I know there are other ways, but these seem like they would be good ones...): 1. Create an Oracle Materialized View that represents what the HTML table should look like and then create a POJO based on the View that I can then integrate into my JSP. 2. Create POJOs that represent the Oracle tables themselves and then create another POJO that is the View used for the HTML table and then integrate that POJO into my JSP. To me, it seems the Materialized View would possibly offer quicker results which is always what we strive for in web applications. But, if I just create 12 POJOs that represent the Oracle tables and then build POJO Views off of those, I have the advantage of keeping all the code in one place for this and possibility for creating any number of different views and reusable components in my web application. Any thoughts on which one might be the better route? Or, maybe you know of an even better one?

• Advice: How to convince my newly annointed team lead against writing the code base from scratch

  - by shan23

  I work in a pretty reknowned MNC, and the module that I work in has been assigned to a new "lead". The code base is pretty huge (~130K or more, with inter dependencies on other modules) , but stable - some parts have grown ugly over the years, but its provably in working state. (Our products are running for years on them, even new ones). The problem is, our lead wants to rewrite the code from scratch, to encompass "finer granularity and a proactive design". I know in my guts thats not a very good idea, but how do I convince him/the rest of the team(who are pretty much more senior than me in terms of years of exp), without sounding too pedantic myself (Thou shalt not rewrite , as Joel et al have clear articles prohibiting it)? I have a good working relation with the person concerned, and don't want to ruin it, but neither do I want to be party to a decision which would surely plague us for years to come !! Any suggestions for a milder,yet effective approach ? Even accounts of how you have tackled such a situation to your liking would help me a lot! EDIT: The code base I'm talking about is not a product/GUI, but at kernel level with all the critical functionalities for our product. I hope now you know why i sound so apprehensive !!
