• What is the role of traditional issue tracker when Scrum / Kanban board is used?

  - by Borek

  From a very high level view, to me it seems there are generally 2 types of Project Management tools: Traditional issue trackers like Fogbugz, JIRA, BugZilla, Trac, Redmine etc. Virtual card boards / agile project management tools like Pivotal Tracker, GreenHopper, AgileZen, Trello etc. Sure, they overlap in one way or another, e.g. Pivotal Tracker tasks can be imported to JIRA, GreenHopper itself is implemented on top of JIRA issue base etc. but I think one can still see the difference in orientation between those two types of tools. Traditional issue tracker seems to be used even in companies otherwise doing agile project management. My question is, why do they do that? I also feel that we should use an issue tracker in my company but when I'm thinking about it, I'm not actually sure why should we need it. For example, Trello development seems to be managed by using Trello itself (see this virtual wall) even though they have access to Fogbugz, one of the best issue trackers around. So maybe we don't need traditional issue tracker when we'll be doing 100% of our work in an agile manner using one of the agile PM tools?

• What makes a person contribute to opensource? [duplicate]

  - by Jibin

  This question already has an answer here: Why develop free, open source programs? [closed] 14 answers I know this is controversial, but.. There are many great projects like Apache Webserver or Hadoop provided by the OpenSource Community. I often feel that the people that actually benefit (financially), from these projects are developers like me, sitting in India, working for MNCs, who has never contributed anything to any opensource project so far, but earn handsomely due to my basic googling skills & the community provided documentation. Is it fair ? I mean no other industry in the world face such dilemma.Those who work get paid. I mean I almost am starting to feel guilty of taking such advantage of some thing that I contribute nothing to. I had to do projects every semester in college (we could choose projects) & I used to enjoy coding then. I want to contribute. But contributing to opensource is not a task [unlike college or office work]. And life is so busy .. Are all these opensource contributors really jobless ?[just kidding..] Could someone please share some personal experiences on how you guys started contributing or any advice on why I should contribute or what attitude in life makes you keep aside time or is it that you just crazly love writing code or is it that you just love to see your name in the contributors list or do you have a local coding group you hang out with ? Do you feel I am destined to do this ? This is my part of contributing back to the world ? Whats that basic mentality that make you guys want to contribute, while I just want to finish my work and go home. What makes you guys tick ?

• JUnit Testing in Multithread Application

  - by e2bady

  This is a problem me and my team faces in almost all of the projects. Testing certain parts of the application with JUnit is not easy and you need to start early and to stick to it, but that's not the question I'm asking. The actual problem is that with n-Threads, locking, possible exceptions within the threads and shared objects the task of testing is not as simple as testing the class, but testing them under endless possible situations within threading. To be more precise, let me tell you about the design of one of our applications: When a user makes a request several threads are started that each analyse a part of the data to complete the analysis, these threads run a certain time depending on the size of the chunk of data (which are endless and of uncertain quality) to analyse, or they may fail if the data was insufficient/lacking quality. After each completed its analysis they call upon a handler which decides after each thread terminates if the collected analysis-data is sufficient to deliver an answer to the request. All of these analysers share certain parts of the applications (some parts because the instances are very big and only a certain number can be loaded into memory and those instances are reusable, some parts because they have a standing connection, where connecting takes time, ex.gr. sql connections) so locking is very common (done with reentrant-locks). While the applications runs very efficient and fast, it's not very easy to test it under real-world conditions. What we do right now is test each class and it's predefined conditions, but there are no automated tests for interlocking and synchronization, which in my opionion is not very good for quality insurances. Given this example how would you handle testing the threading, interlocking and synchronization?

• Usage of repository between EF model and code consumer

  - by jim

  I have binary data in my database that I'll have to convert to bitmap at some point. I was thinking whether or not it's appropriate to use a repository and do it there. My consumer, which is a presentation layer, will use this repository. For example: // This is a class I created for modeling the item as is. public class RealItem { public string Name { get; set; } public Bitmap Image { get; set; } } public abstract class BaseRepository { //using Unity (http://unity.codeplex.com) to inject the dependancy of entity context. [Dependency] public Context { get; set; } } public calss ItemRepository : BaseRepository { public List<Items> Select() { IEnumerable<Items> items = from item in Context.Items select item; List<RealItem> lst = new List<RealItem>(); foreach(itm in items) { MemoryStream stream = new MemoryStream(itm.Image); Bitmap image = (Bitmap)Image.FromStream(stream); RealItem ritem = new RealItem{ Name=item.Name, Image=image }; lst.Add(ritem); } return lst; } } Is this a correct way to use the repository pattern? I'm learning this pattern and I've seen a lot of examples online that are using a repository but when I looked at their source code... for example: public IQueryable<object> Select { return from q in base.Context select q; } as you can see no behavior is added to the system by their approach, so I was confused that maybe repository is something else and I got it all wrong. At the end there should be extra benifits of using them right?

• How to Enable User-Specific Wireless Networks in Windows 7

  - by The Geek

  Wireless network settings in Windows 7 are global across all users, but there’s a little-known option that lets you switch them to per-user, so each user has access to only the networks they are allowed to connect to. Here’s how it all works. How is this useful? Maybe you want to prevent a particular user from accessing the internet—if you don’t give them the wireless password, they won’t be able to get online. This could be very useful if you’ve got mini-people playing games on the family PC, but you don’t want them getting online Latest Features How-To Geek ETC How to Enable User-Specific Wireless Networks in Windows 7 How to Use Google Chrome as Your Default PDF Reader (the Easy Way) How To Remove People and Objects From Photographs In Photoshop Ask How-To Geek: How Can I Monitor My Bandwidth Usage?

• How can I call a URL as a cron job in Webmin?

  - by EmmyS

  (Possibly this belongs on stackoverflow, although it's not really a programming issue since the code works when run directly. If it needs to be moved, though, no problem.) I have a PHP file (which consumers a National Weather Service web service via SOAP, if it matters) that I need to run on a scheduled basis. I'm trying to set up a cron job in Webmin. If I use an absolute path to the file in the Command field, when I run it I get some strange errors: /var/www/html/mysite.com/test/ndfdXMLclient.php: line 1: ?php: No such file or directory /var/www/html/mysite.com/test/ndfdXMLclient.php: line 2: //: is a directory /var/www/html/mysite.com/test/ndfdXMLclient.php: line 3: //DOCUMENTATION: No such file or directory /var/www/html/mysite.com/test/ndfdXMLclient.php: line 4: //: is a directory /var/www/html/mysite.com/test/ndfdXMLclient.php: line 5: syntax error near unexpected token `"running client code",' /var/www/html/mysite.com/test/ndfdXMLclient.php: line 5: `error_log("running client code", 1, "[email protected]");' The actual code in my file for those 5 lines looks like this: <?php // *************************************************************************** //DOCUMENTATION FROM WEATHER.GOV ALL STORED IN xmlClientComments.txt // *************************************************************************** error_log("running client code", 1, "[email protected]"); The code runs perfectly fine when I run it directly in my browser, so why doesn't webmin recognize it as code? (The same thing happens if I enter the actual URL in the command field - http://mysite.com/test/ndfdXMLclient.php.) I've never worked with webmin before; most of our hosts' cron control panels allow cron jobs to run PHP files like this with no issue. Is there some trick to getting webmin to read php as actual php?

• HTG Explains: What Are Computer Algorithms and How Do They Work?

  - by YatriTrivedi

    Unless you’re into math or programming, the word “algorithm” might be Greek to you, but it’s one of the building blocks of everything you’re using to read this article. Here’s a quick explanation of what they are, and how they work. Disclaimer: I’m not a math or computer science teacher, so not all of the terms I use are technical. That’s because I’m trying to explain everything in plain English for people aren’t quite comfortable with math. That being said, there is some math involved, and that’s unavoidable. Math geeks, feel free to correct or better explain in the comments, but please, keep it simple for the mathematically disinclined among us.

• How is"cloud computing"different from "client-server"?

  - by BellevueBob

  Watching a CEO for a new "cloud computing" company describe his company on a finance TV program today, he said something like "Cloud computing is superior to old-fashioned client-server computing". Now I'm confused. Can someone please explain what "cloud computing" means in contrast to client-server? As far as I understand it, cloud computing is more of a network services model, such that I do not own or maintain the physical hardware. The "cloud" is all the back-end stuff. But I still might have an application that communicates with that "cloud" environment. And if I run a web site presents a form that a user fills out, pushes a button on the page, and returns some report that was generated by the web server, isn't that the same as "cloud" computing? And would you not consider my web browser as the "client"? Please note my question is specific to the concept of "cloud computing" with respect to "client-server". Sorry if this is an inappropriate question for this site; it's the one closest in the Stack universe and this is my first time here. I'm an old timer, programming since mainframe days in the late 70's.

• Is micro-optimisation important when coding?

  - by BozKay

  I recently asked a question on stackoverflow.com to find out why isset() was faster than strlen() in php. This raised questions around the importance of readable code and whether performance improvements of micro-seconds in code were worth even considering. My father is a retired programmer, I showed him the responses and he was absolutely certain that if a coder does not consider performance in their code even at the micro level, they are not good programmers. I'm not so sure - perhaps the increase in computing power means we no longer have to consider these kind of micro-performance improvements? Perhaps this kind of considering is up to the people who write the actual language code? (of php in the above case). The environmental factors could be important - the internet consumes 10% of the worlds energy, I wonder how wasteful a few micro-seconds of code is when replicated trillions of times on millions of websites? I'd like to know answers preferably based on facts about programming. Is micro-optimisation important when coding? EDIT : My personal summary of 25 answers, thanks to all. Sometimes we need to really worry about micro-optimisations, but only in very rare circumstances. Reliability and readability are far more important in the majority of cases. However, considering micro-optimisation from time to time doesn't hurt. A basic understanding can help us not to make obvious bad choices when coding such as if (expensiveFunction() && counter < X) Should be if (counter < X && expensiveFunction()) (example from @zidarsk8) This could be an inexpensive function and therefore changing the code would be micro-optimisation. But, with a basic understanding, you would not have to because you would write it correctly in the first place.

• 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.

• Starting to Program C++ and Java

  - by user0321

  So as the title states, I'm trying to start programming in C++ and Java. I took C++ and Java courses in high school and I'm trying to get back into it. Of course all I want to get working now is a simple "Hello World" program. Couple of things: I want to use an IDE. I've decided on Eclipse. I'm just confused about how I go about downloading/using it. For Java: I get stuck right on their download page. They show Eclipse Classic, Eclipse IDE for Java developers and Eclipse IDE for Java EE Developers. I only programmed in Notepad and compiled in command prompt. Question 1: Which version of Eclipse should I download? Question 2: Do I need to install the Java JDK or does it come built into Eclipse? For C++: I guess I download the separate Eclipse IDE for C/C++ developers? I'm not too sure. I remember using Microsoft Visual for C++. I remember it being weird though. Anyways Question 3: Which version of Eclipse should I download? Question 4: Does C++ have a Development Kit or does it come built into Eclipse?

• 12.04 wired network doesn't work RTL8111/8168B

  - by laket

  its a fresh 12.04 install 64bits. wifi works fine, wired stays off with cable connected and network-manager shows as if cable is disconnected. Turning off networking lights up my network-cards leds, turning networking on shuts off the leds and no communication is possible. I already tried, turning off the network-manager (sudo service network-manager stop) and setting up my eth0 manually, as soon as I switch off the network-manager my leds light up, but after setting up manually eth0 (sudo ifconfig eth0 10.2.10.114 netmask 255.255.0.0 up) the leds turn off again. I am still dual booting with 10.04 where I have no issues at all, leaving the cable connected all time to my notebook and a switch.

• Algorithm for dynamically calculating a level based on experience points?

  - by George

  One of the struggles I've always had in game development is deciding how to implement experience points attributed to gaining a level. There doesn't seem to be a pattern to gaining a level in many of the games I've played, so I assume they have a static dictionary table which contains experience points vs. the level. e.g. Experience Level 0 1 100 2 175 3 280 4 800 5 ...There isn't a rhyme or reason why 280 points is equal to level 4, it just is. I'm not sure how those levels are decided, but it certainly wouldn't be dynamic. I've also thought about the possibility of exponential levels, as not to have to keep a separate lookup table, e.g. Experience Level 0 1 100 2 200 3 400 4 800 5 1600 6 3200 7 6400 8 ...but that seems like it would grow out of control rather quickly, as towards the upper levels, the enemies in the game would have to provide a whopping amount of experience to level -- and that would be to difficult to control. Leveling would become an impossible task. Does anyone have any pointers, or methods they use to decide how to level a character based on experience? I want to be fair in leveling and I want to stay ahead of the players as not to worry about constantly adding new experience/level lookups.

• A new mission statement for my school's algorithms class

  - by Eric Fode

  The teacher at Eastern Washington University that is now teaching the algorithms course is new to eastern and as a result the course has changed drastically mostly in the right direction. That being said I feel that the class could use a more specific, and industry oriented (since that is where most students will go, though suggestions for an academia oriented class are also welcome) direction, having only worked in industry for 2 years I would like the community's (a wider and much more collectively experienced and in the end plausibly more credible) opinion on the quality of this as a statement for the purpose an algorithms class, and if I am completely off target your suggestion for the purpose of a required Jr. level Algorithms class that is standalone (so no other classes focusing specifically on algorithms are required). The statement is as follows: The purpose of the algorithms class is to do three things: Primarily, to teach how to learn, do basic analysis, and implement a given algorithm found outside of the class. Secondly, to teach the student how to model a problem in their mind so that they can find a an existing algorithm or have a direction to start the development of a new algorithm. Third, to overview a variety of algorithms that exist and to deeply understand and analyze one algorithm in each of the basic algorithmic design strategies: Divide and Conquer, Reduce and Conquer, Transform and Conquer, Greedy, Brute Force, Iterative Improvement and Dynamic Programming. The Question in short is: do you agree with this statement of the purpose of an algorithms course, so that it would be useful in the real world, if not what would you suggest?

• Heading to GTC 2010

  - by Daniel Moth

  Next week the GPU Technology Conference (GTC) 2010 takes place in San Jose, CA and I am lucky enough to be attending the entire week. It has been an extremely long time (in fact, I can't remember the last time) where I am registered as an attendee at a conference (full pass/access) without being a speaker *and* without having any booth duty! Having said that, we (our team at Microsoft) will be running GPU debugging UX studies throughout the entire week (similar to what I had previously advertised). If you are attending GTC 2010 and you are interested, look for the related flyer in your conference bag. The conference is an excellent opportunity to connect in-person with various individuals that I have only met virtually. From an educational perspective there is a very long and interesting session list, with multiple concurrent slots, making it very hard to choose between them, but I have managed to create my (packed) schedule. I am most looking forward to sessions on the programming languages and tools, both from Microsoft and MS partners. For full conference details, visit the GTC 2010 official page. Comments about this post welcome at the original blog.

• MapReduce

  - by kaleidoscope

  MapReduce is a programming model and an associated implementation for processing and generating large data sets. Users specify a map function that processes a key/value pair to generate a set of  intermediate key/value pairs, and a reduce function that merges all intermediate values associated with the same intermediate key. Many real world tasks are expressible in this model, as shown in the paper. Programs written in this functional style are automatically parallelized and executed on a large cluster of commodity machines. The run-time system takes care of the details of partitioning the input data,  scheduling the program's execution across a set of machines, handling machine failures, and managing the required inter-machine communication. This allows programmers without any experience with parallel and distributed systems to easily utilize the resources of a large distributed system. Example: A process to count the appearances of each different word in a set of documents void map(String name, String document):   // name: document name   // document: document contents   for each word w in document:     EmitIntermediate(w, 1); void reduce(String word, Iterator partialCounts):   // word: a word   // partialCounts: a list of aggregated partial counts   int result = 0;   for each pc in partialCounts:     result += ParseInt(pc);   Emit(result); Here, each document is split in words, and each word is counted initially with a "1" value by the Map function, using the word as the result key. The framework puts together all the pairs with the same key and feeds them to the same call to Reduce, thus this function just needs to sum all of its input values to find the total appearances of that word.   Sarang, K

• Turn-based JRPG battle system architecture resources

  - by BenoitRen

  The past months I've been busy programming a 2D JRPG (Japanese-style RPG) in C++ using the SDL library. The exploration mode is more or less done. Now I'm tackling the battle mode. I have been unable to find any resources about how a classic turn-based JRPG battle system is structured. All I find are discussions about damage formula. I've tried googling, searching gamedev.net's message board, and crawling through C++-related questions here on Stack Exchange. I've also tried reading source code of existing open source RPGs, but without a guide of some sort it's like trying to find a needle in a haystack. I'm not looking for a set of rules like D&D or anything similar. I'm talking purely about code and object structure design. A battle system asks the player for input using menus. Next the battle turn is executed as the heroes and the enemies execute their actions. Can anyone point me in the right direction? Thanks in advance.

• Rendering a big game universe - bitmaps or vector graphics?

  - by user1641923

  I am new to an Android development, though I have much experience with Java, C++, PHP programming and a bit experience with vector graphics too (basic 3d Studio Max, Flash, etc). I am starting to work on an Android game. It is going to be a 2D space shooter/RPG, and I am not going to use any game engines and any 3D party libs. I really want to create a very large game universe, or even pseudo-infinite (without visible borders, as if it were a 2D projection of a sphere). It should include 10-12 clusters of 7-8 planets/other space objects and random amount of single asteroids/comets, which player can interact with and also not interactive background. I am looking for a least complicated aproach to create such a universe. My current ideas are: Simply create bitmaps with space scenery background so that they can be tiled seamlessly repeated and construct my 2D universe of this tiles, then place interactive objects (planets, other spaceships) on it. Using vector graphics. I would have a solid color background, some random background objects and gradients here and there. My problems here: Lack of knowledge of how well vector graphics is integrated in Android. Performance? Memory usage? Does Android manage big bitmaps well? Do all of the bitmaps have to be in memory during all game process? I am interested in technical details regarding each of the ideas and a suggestion, which I should go with.

• Mobile cross-platform SDK for computationally intensive apps

  - by K.Steff

  I am aware of the PhoneGap toolkit for creating mobile applications for virtually all mobile platforms with a significant market share. However, the code in PhoneGap that is shared between the different platforms is written in JavaScript. While I like JS, I think it's hardly appropriate for computationally intensive tasks. The situation with Titanium is pretty much the same. So, is there any way that I can create a cross-platform mobile app that has the computationally intensive code shared between the platforms? Some context: Obviously, I don't want to implement the time consuming algorithm in many different languages, since this violates DRY, increases the chance for bugs slipping in at least one version and require boilerplate code to work. I've looked at Xamarin's MonoTouch and Mono for Android tools, but while they cover iOS and Android, they're not nearly as versatile for deployment as PhoneGap. On the other hand, (IMO) the statically typed nature of C# is more suited for intense computation than JS. Are there any other SDK/tools appropriate for the task that I don't know about or a point about the mentioned above that I've missed? Also, uploading data to a web service for processing is not an option, because of the traffic required.

• OUM is Flexible and Scalable

  - by user535886

  Flexible and Scalable Traditionally, projects have been focused on satisfying the contents of a requirements document or rigorously conforming to an existing set of work products. Often, especially where iterative and incremental techniques have not been employed, these requirements may be inaccurate, the previous deliverables may be flawed, or the business needs may have changed since the start of the project. Fitness for business purpose, derived from the Dynamic Systems Development Method (DSDM) framework, refers to the focus of delivering necessary functionality within a required timebox. The solution can be more rigorously engineered later, if such an approach is acceptable. Our collective experience shows that applying fit-for-purpose criteria, rather than tight adherence to requirements specifications, results in an information system that more closely meets the needs of the business. In OUM, this principle is extended to refer to the execution of the method processes themselves. Project managers and practitioners are encouraged to scale OUM to be fit-for-purpose for a given situation. It is rarely appropriate to execute every activity within OUM. OUM provides guidance for determining the core set of activities to be executed, the level of detail targeted in those activities and their associated tasks, and the frequency and type of end user deliverables. The project workplan should be developed from this core. The plan should then be scaled up, rather than tailored down, to the level of discipline appropriate to the identified risks and requirements. Even at the task level, models and work products should be completed only to the level of detail required for them to be fit-for-purpose within the current iteration or, at the project level, to suit the business needs of the enterprise and to meet the contractual obligations that govern the project. OUM provides well defined templates for many of its tasks. Use of these templates is optional as determined by the context of the project. Work products can easily be a model in a repository, a prototype, a checklist, a set of application code, or, in situations where a high degree of agility is warranted, simply the tacit knowledge contained in the brain of an analyst or practitioner. For further reading on agility, see Balancing Agility and Discipline: A guide fro the Perplexed.

• Procedural world generation oriented on gameplay features

  - by Richard Fabian

  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.
