• Why C# does not support multiple inheritance?

  - by Jalpesh P. Vadgama

  Yesterday, One of my friend Dharmendra ask me that why C# does not support multiple inheritance. This is question most of the people ask every time. So I thought it will be good to write a blog post about it. So why it does not support multiple inheritance? I tried to dig into the problem and I have found the some of good links from C# team from Microsoft for why it’s not supported in it. Following is a link for it. http://blogs.msdn.com/b/csharpfaq/archive/2004/03/07/85562.aspx Also, I was giving some of the example to my friend Dharmendra where multiple inheritance can be a problem.The problem is called the diamond problem. Let me explain a bit. If you have class that is inherited from the more then one classes and If two classes have same signature function then for child class object, It is impossible to call specific parent class method. Here is the link that explains more about diamond problem. http://en.wikipedia.org/wiki/Diamond_problem Now of some of people could ask me then why its supporting same implementation with the interfaces. But for interface you can call that method explicitly that this is the method for the first interface and this the method for second interface. This is not possible with multiple inheritance. Following is a example how we can implement the multiple interface to a class and call the explicit method for particular interface. Multiple Inheritance in C# That’s it. Hope you like it. Stay tuned for more update..Till then happy programming.

• Advice on a good comeback strategy after years of java abstinence

  - by simou

  It's almost 5 yrs since I left the java IT-project/enterprise business. Before I was a highly skilled enterprise developer / OO architect with more than 10 years experience in the business. I was proficient in many of those enterprise related technologies, including DWHing. Since then I haven't been doing any large scale programming, a little bit of C, Python, some dips into Scala, hacking a small java-plugin framework, opengl, but only as fun projects. Now I want to re-enter the java stage again, i.e. I'm looking for job opportunities as a developer. But I fear I might have lost much of my former punching strength, e.g. I would have to give my SQL knowledge a deep refreshing breath, re-visit basic stuff like design patterns, enterprise architectures, etc. and probably learn the new stuff like EJB3.1, JEE 6 too. I also missed the whole scrum craze. So from your own experience, what subject should I tackle first? Like technology (which ones?) or design skills (uml..)? But what I'm also wondering is since the basic design / architectural principles haven't changed much by now, what would be the chance on the job market for someone like me who left the java-world at a time where everything was less fragmented and EJB2.1 and XDoclet were de-facto standards? And how could I convince a potential employer that I'm still an effective on-the-job learner? Should I rather aim for "junior positions" ? Lots of questions but I'd be really glad if you could share your (encouraging :) thoughts with me. cheers! (btw I'm based in Austria)

• Restful Java based web services in json + html5 and javascript no templates (jsp/jsf/freemarker) aka fat/thick client

  - by Ismail Marmoush

  I have this idea of building a website which service JSON data through restful services framework. And will not use any template engines like jsp/jsf/freemarker. Just pure html5 and Javascript libs. What do you think of the pros and cons of such design ? Just for elaboration and brain storming a friend of mine argued with the following concerns: sounds like gwt this way you won't have any control over you service api for example say you wanna charge the user per request how will you handle it? how will you control your design and themes? what about the 1st request the browser make? not easy with this all of the user's requests will come with "Accept" header "application/json" how will you separate browser from abuser? this way all of your public apis will be used by third party apps abusively and you won't be able to lock it since you won't be able to block the normal user browser We won't use compiled html anyway but may be something like freemarker and in that case you won't expose any of your json resources to the unauthorized user but you will expose all the html since any browser can access them all the well known 1st class services do this can you send me links to what you've read? keep in mind the DOM based XSS it will be a nightmare ofc, if what you say is applicable.

• [Dear Recruiter] I developed in Mo'Fusion

  - by refuctored

  Forward: Sometimes I really feel like technology recruiters have no experience or knowledge of the field they are recruting for.  A warning to those companies hiring technical recruiters -- ensure that the technical recruiters you hire to fill a position are actually technical.  Here's proof below, where I make up completely ridiculous technologies, but still have interest from the recruiter for an interview. Letter to me: Hello - Your name came up as a possible match for a long term contract Cold Fusion Developer role I have in Bothell, WA.  This role requires you to be onsite in Bothell, WA. This is  a tough role to fill so I was hoping you might have someone you can recommend? Unfortunately no telecommute. Thank you! Sincerly, Mindy Recruiter My response: Mindy -- Wow I'm super-excited that you took the time to contact me about this position!  Let me tell you, you won't be disappointed with my skill set! Firstly, I've been developing in ColdFusion since 1993 before it was owned by Adobe and it was operating under code name, "Hot-Jack".  Recently I started developing under the Domain-View-Driven-Domain-Model (DVDDM), integrating client-side CF on Moobuntu.  Not only do I have a boat load of ColdFusion EXP,  I also have a ton of experience in the open source communities lesser known derivative of CF, Mo'Fusion (MF).  I've also invested thousands of hours of my time learning esoteric programming languages. Look forward to working with you! George And her response: Hi George – just left you a message. Give me a call at your convenience.  The role does require someone to be onsite here.. are you able to relocate yourself? Mindy [Sigh]

• Platformer Enemy AI

  - by hayer

  I'm currently developing a platformer shooter. The game is multiplayer and while my net code could use some real work I have put that off for the time, so currently I'm trying to implement the AI. The game is pretty simple; Players run around on a map filled with a X amount of zombies that try to eat their brains, classic and overused I know. Weapons spawn at random intervals around the map. The problem is that the zombies, when they find their pray the have to follow it for some while.. And here is the problem, running the AI navcode seems to take for ever. So here is the ideas I have come up with so far Have the AI update at different intervals with a maximum of Y ms with no updates. Have the zombies assigned to groups of zombies. One is appointed the leader of the group who finds the way to the player - the rest just follows the leader. If the leader dies another one of the zombies in the group is appointed president of the zombie swarm. If there is less than five zombies in a group they try to meet up with other zombies.(Aka they are assigned to a different group and therefor a new leader) Multi-threading option one or two? For navigation I have some kinda navmesh(since the game is not tile-based) that tells the zombies where they can walk etc. If anyone else got some ideas on how to do navigation I would love some input. For LoS(zombie - player) I have split the map into grids. If the players grid is connected to the zombies grid(if I go with option two I would only need to check if leader zombies grid is connected to player, aka less checks) - if they are connected and there is more than 250ms since last check do a raytrace.. This is my first time programming AI so input on any field is appreciated.

• In the days of modern computing, in 'typical business apps' - why does performance matter?

  - by Prog

  This may seem like an odd question to some of you. I'm a hobbyist Java programmer. I have developed several games, an AI program that creates music, another program for painting, and similar stuff. This is to tell you that I have an experience in programming, but not in professional development of business applications. I see a lot of talk on this site about performance. People often debate what would be the most efficient algorithm in C# to perform a task, or why Python is slow and Java is faster, etc. What I'm trying to understand is: why does this matter? There are specific areas of computing where I see why performance matters: games, where tens of thousands of computations are happening every second in a constant-update loop, or low level systems which other programs rely on, such as OSs and VMs, etc. But for the normal, typical high-level business app, why does performance matter? I can understand why it used to matter, decades ago. Computers were much slower and had much less memory, so you had to think carefully about these things. But today, we have so much memory to spare and computers are so fast: does it actually matter if a particular Java algorithm is O(n^2)? Will it actually make a difference for the end users of this typical business app? When you press a GUI button in a typical business app, and behind the scenes it invokes an O(n^2) algorithm, in these days of modern computing - do you actually feel the inefficiency? My question is split in two: In practice, today does performance matter in a typical normal business program? If it does, please give me real-world examples of places in such an application, where performance and optimizations are important.

• Get Smarter Just By Listening

  - by mark.wilcox

  Occasionally my friends ask me what do I listen/read to keep informed. So I thought I would like to post an update. First - there is an entirely new network being launched by Jason Calacanis called "ThisWeekIn". They have weekly shows on variety of topics including Startups, Android, Twitter, Cloud Computing, Venture Capital and now the iPad. If you want to keep ahead (and really get motivated) - I totally recommend listening to at least This Week in Startups. I also find Cloud Computing helpful. I also like listening to the Android show so that I can see how it's progressing. Because while I love my iPhone/iPad - it's  important to keep the competition in the game up to improve everything. I'm also not opposed to switching to Android if something becomes as nice experience - but so far - my take on Android devices are  - 10 years ago, I would have jumped all over them because of their hackability. But now, I'm in a phase, where I just want these devices to work and most of my creation is in non-programming areas - I find the i* experience better. Second - In terms of general entertaining tech news - I'm a big fan of This Week in Tech. Finally - For a non-geek but very informative show - The Kevin Pollack Show on ThisWeekIn network gets my highest rating. It's basically two-hours of in-depth interview with a wide variety of well-known comedian and movie stars. -- Posted via email from Virtual Identity Dialogue

• How to handle wildly varying rendering hardware / getting baseline

  - by edA-qa mort-ora-y

  I've recently started with mobile programming (cross-platform, also with desktop) and am encountering wildly differing hardware performance, in particular with OpenGL and the GPU. I know I'll basically have to adjust my rendering code but I'm uncertain of how to detect performance and what reasonable default settings are. I notice that certain shader functions are basically free in a desktop implemenation but can be unusable in a mobile device. The problem is I have no way of knowing what features will cause what performance issues on all the devices. So my first issue is that even if I allow configuring options I'm uncertain of which options I have to make configurable. I'm wondering also wheher one just writes one very configurable pipeline, or whether I should have 2 distinct options (high/low). I'm also unsure of where to set the default. If I set to the poorest performer the graphics will be so minimal that any user with a modern device would dismiss the game. If I set them even at some moderate point, the low end devices will basically become a slide-show. I was thinking perhaps that I just run some benchmarks when the user first installs and randomly guess what works, but I've not see a game do this before.

• Web to Print system - which client side technology should I use

  - by mr null

  I'm getting started to develop Web to Print system. My main concern is which client-side techology should I use: jQuery/CSS Flex/ActionScript or something else? For now, idea is that user/customer choose Product eg: Business card Attributes: Dimensions,Paper type, ... etc Template or blank Adjust product (editor) Preview & order Output should be PDF 300dpi. My main issue is: adding/adjusting text in editor. (font size, font family...). Because application should be cross browser. And I think that 10px Arial can't be the same in Firefox 5 and IE 8. It must be pixel perfect in every browser. If somebody order $100 of business cards, and text is different that he/she saw when ordering - that is a big problem. So, Flash platform should be the answer. But, as I see it's dying technology, 2012 is here - HTML5 is replacing Flash rapidly. I hope that you understand me, so every guideline or few smart words would be very appreciating.

• Why do programmers write applications and then make them free?

  - by Ken

  As an entrepreneur/programmer who makes a good living from writing and selling software, I'm dumbfounded as to why developers write applications and then put them up on the Internet for free. You've found yourself in one of the most lucrative fields in the world. A business with 99% profit margin, where you have no physical product but can name your price; a business where you can ship a buggy product and the customer will still buy it. Occasionally some of our software will get a free competitor, and I think, this guy is crazy. He could be making a good living off of this but instead chose to make it free. Do you not like giant piles of money? Are you not confident that people would pay for it? Are you afraid of having to support it? It's bad for the business of programming because now customers expect to be able to find a free solution to every problem. (I see tweets like "is there any good FREE software for XYZ? or do I need to pay $20 for that".) It's also bad for customers because the free solutions eventually break (because of a new OS or what have you) and since it's free, the developer has no reason to fix it. Customers end up with free but stale software that no longer works and never gets updated. Customer cries. Developer still working day job cries in their cubical. What gives? PS: I'm not looking to start an open-source/software should be free kind of debate. I'm talking about when developers make a closed source application and make it free.

• Whats the greatest most impressive programing feat you ever witnessed? [closed]

  - by David Reis

  Everyone knows of the old adage that the best programmers can be orders of magnitude better than the average. I've personally seen good code and programmers, but never something so absurd. So the questions is, what is the most impressive feat of programming you ever witnessed or heard of? You can define impressive by: The scope of the task at hand e.g. John single handedly developed the framework for his company, a work comparable in scope to what the other 200 employed were doing combined. Speed e.g. Stu programmed an entire real time multi-tasking app OS on an weekened including its own C compiler and shell command line tools Complexity e.g. Jane rearchitected our entire 10 millon LOC app to work in a cluster of servers. And she did it in an afternoon. Quality e.g. Charles's code had a rate of defects per LOC 100 times lesser than the company average. Furthermore he code was clean and understandable by all. Obviously, the more of these characteristics combined, and the more extreme each of them, the more impressive is the feat. So, let me have it. What's the most absurd feat you can recount? Please provide as much detail as possible and try to avoid urban legends or exaggerations. Post only what you can actually vouch for. Bonus questions: Was the herculean task a one-of, or did the individual regularly amazed people? How do you explain such impressive performance? How was the programmer recognized for such awesome work?

• The Case of the Invisible Training Resource

  - by GGBlogger

  I’ve been at this programming business longer than I would like to admit. For that reason I am always looking for new training resources as anyone in this business knows all too well. I’ve looked at AppDev (way too expensive for my meager budget), LearnVisualStudio (I have a lifetime subscription), and several others. What appears to be a new version of AppDev called LearnDevNow has some good material and so it goes. So what does all this have to do with the title? I’ve been using Adobe’s Flex Builder 3 and now their latest Flash Builder 4 (a renaming of the Adobe Flex development environment). One of the offered perks on registering was a month’s subscription to Lynda.com. My first reaction was “What the heck is Lynda.com?” but I chose it and signed up. What a surprise I was in for. I’d never heard of them before but discovered one of the most comprehensive training resources I’ve ever seen – and all for $ 34.95 a month in the version that offers Exercise files. They do have a heavy focus on Adobe products but also cover a lot of Microsoft material. What bothered me is that in the time I’ve been in this business I’d never heard of them! ; Thus the allusion to “The Invisible Training Resource.” Not only do they offer beginner and in depth training but the syllabus and the instructors are some of the best I’ve seen in the industry. So I just feel that more folks need to know about this organization. If you need training in the venues they offer I can attest to the fact that they offer some of the best training available in this industry in my humble opinion. You really owe it to yourself to check out Lynda.com.

• How to visualize the design of a program in order to communicate it to others

  - by Joris Meys

  I am (re-)designing some packages for R, and I am currently working out the necessary functions, objects, both internal and for the interface with the user. I have documented the individual functions and objects. So I have the description of all the little parts. Now I need to give an overview of how the parts fit together. The scheme of the motor so to say. I've started with making some flowchart-like graphs in Visio, but that quickly became a clumsy and useless collection of boxes, arrrows and-what-not. So hence the question: Is there specific software you can use for vizualizing the design of your program If so, care to share some tips on how to do this most efficiently If not, how do other designers create the scheme of their programs and communicate that to others? Edit: I am NOT asking how to explain complex processes to somebody, nor asking how to illustrate programming logic. I am asking how to communicate the design of a program/package, i.e.: the objects (with key features and representation if possible) the related functions (with arguments and function if possible) the interrelation between the functions at the interface and the internal functions (I'm talking about an extension package for a scripting language, keep that in mind) So something like this : But better. This is (part of) the interrelations between functions in the old package that I'm now redesigning for obvious reasons :-) PS : I made that graph myself, using code extraction tools on the source and feeding the interrelation matrix to yEd Graph Editor.

• Game Trees Conceptual Question

  - by Chris Corbin

  I am struggling to conceptually understand a question in a programming assignment for an algorithms class. The problem is dealing with a fictitious 2 player game, named Easy. The rules of the game are simple; each player may chose one of 4 integers {0-3} after which that integer is not available for the other player. The catch is, a player picks {0} it means they quit. The objective is for Player 1 to get {1} and Player 2 to get {2}, in which case they may win, however if both or neither succeed, then the game ends in a draw. I have been asked to draw the game tree for Easy, showing all nodes, which they explained as 4! = 24. Labeling the edges, which represent moves (selecting a number) and the leaves with who won (1 means Player 1 won, -1 means Player 2 won, and 0 means a tie). I have drawn out a game tree, which I believe is correct, however I am not 100% certain hence I am asking the question. My game tree only has 16 leaves. I am thinking that when a player picks {0}, and then quits, the game tree stops there? I don't see how it is possible to get to 24 leaves? Any help would be greatly appreciate, and if you need more information I would be happy to provide it. Thanks

• Comparing the Performance of Visual Studio's Web Reference to a Custom Class

  As developers, we all make assumptions when programming. Perhaps the biggest assumption we make is that those libraries and tools that ship with the .NET Framework are the best way to accomplish a given task. For example, most developers assume that using ASP.NET's Membership system is the best way to manage user accounts in a website (rather than rolling your own user account store). Similarly, creating a Web Reference to communicate with a web service generates markup that auto-creates a proxy class, which handles the low-level details of invoking the web service, serializing parameters, and so on. Recently a client made us question one of our fundamental assumptions about the .NET Framework and Web Services by asking, "Why should we use proxy class created by Visual Studio to connect to a web service?" In this particular project we were calling a web service to retrieve data, which was then sorted, formatted slightly and displayed in a web page. The client hypothesized that it would be more efficient to invoke the web service directly via the HttpWebRequest class, retrieve the XML output, populate an XmlDocument object, then use XSLT to output the result to HTML. Surely that would be faster than using Visual Studio's auto-generated proxy class, right? Prior to this request, we had never considered rolling our own proxy class; we had always taken advantage of the proxy classes Visual Studio auto-generated for us. Could these auto-generated proxy classes be inefficient? Would retrieving and parsing the web service's XML directly be more efficient? The only way to know for sure was to test my client's hypothesis. Read More >

• installing ubuntu on SSD

  - by kunal

  Going to install Ubuntu 10.10 on new intel x25M 80GB SSD. It will be fresh install. I have been googling for past few days and getting overwhelming articles/blogs/Q&As. One particularly very useful being: Optimize for SSD (I could not post other links as i dont have enough credits) But with so many suggestions and differences of opinions (on different links) this simple OS install process seems to be daunting task to me and I really want to stick with ubuntu (although have used for very short period of time). Can someone help me by answering few questions (yes they are repeated as i couldnt comprehend the answers elsewhere) which file system (ext2/3/4 or something else)? (consider SSD life) can it be changed after installation? should i partition the disk? (as we do in traditional HDD) for now, no plan of dual booting. Only ubuntu will live on scarce space of 80GB SSD. i have 2 GB RAM, should i still allocate swap space (if i dont allocate swap space, can i still hibernate the machine)? will swap space impact SSD life? should i consider putting additional 1GB RAM to avoid swap space? Linux experience - absolute novice intended usage - heavy browsing, programming, regular video/music and some other non-CPU/RAM-intensive programs. will backup big files to an external hard drive. laptop config - 3 yr old vaio, core2 duo, 2GB RAM Please pardon the repetition and i really appreciate anyone helping me getting started with ubuntu.

• Example of persisting an inheritance relationship using ORM

  - by Schemer

  I have some experience with OOP and RDBs, but very little exposure to web programming. I am trying to understand what non-trivial types of problems are solved by ORM. Of course, I am familiar with the need for data persistence, but I have never encountered a need for persisting relationships between objects, a situation which is indicated in many online articles about ORM. I am not asking about the process of persisting a POJO to a database and restoring it later. Nor am I asking about why ORM frameworks are useful -- or a pain in the butt -- for doing so. I am particularly interested in how the need arises to persist and restore relationships between objects. In various documentation, I have seen many examples of persisting POJOs to a database, but the examples have all been for only very simple objects that are essentially nothing more than records anyway: a constructor, some private fields, and getter/setter methods. The motivation for persisting such an "object-record" seems obvious and trivial. This example: Hibernate ORM Tutorial offers such an example, but goes on to discuss mismatch issues of granularity, inheritance, identity, associations, and navigation that are not motivated by the example. If someone could offer a toy example of an instance where, say, the need arises to persist an inheritance relationship, I would be grateful. This might be blindingly obvious for anyone who has already encountered this situation but I have not and a great deal of searching and reading have not turned up any examples.

• Code maintenance: keeping a bad pattern when extending new code for being consistent or not ?

  - by Guillaume

  I have to extend an existing module of a project. I don't like the way it has been done (lots of anti-pattern involved, like copy/pasted code). I don't want to perform a complete refactor. Should I: create new methods using existing convention, even if I feel it wrong, to avoid confusion for the next maintainer and being consistent with the code base? or try to use what I feel better even if it is introducing another pattern in the code ? Precison edited after first answers: The existing code is not a mess. It is easy to follow and understand. BUT it is introducing lots of boilerplate code that can be avoided with good design (resulting code might become harder to follow then). In my current case it's a good old JDBC (spring template inboard) DAO module, but I have already encounter this dilemma and I'm seeking for other dev feedback. I don't want to refactor because I don't have time. And even with time it will be hard to justify that a whole perfectly working module needs refactoring. Refactoring cost will be heavier than its benefits. Remember: code is not messy or over-complex. I can not extract few methods there and introduce an abstract class here. It is more a flaw in the design (result of extreme 'Keep It Stupid Simple' I think) So the question can also be asked like that: You, as developer, do you prefer to maintain easy stupid boring code OR to have some helpers that will do the stupid boring code at your place ? Downside of the last possibility being that you'll have to learn some stuff and maybe you will have to maintain the easy stupid boring code too until a full refactoring is done)
