  • Open source level editor for HTML5 platform game?

    - by Lai Yu-Hsuan
    A natty GUI editor is very helpful to create level map. I want to use some open-source choices rather than build my own from scratch. I found Tiled Map Editor but it doesn't work for what I want. Though I'm building HTML5 game, I don't have to use a HTML5 level editor as long as it can output well-formatted map files which my javascript can read. Edit: Sorry for the confusion. Tiled does not work for me because to make the player perform a 'tricky' jump, sometimes I want to set the distance between two platforms to, say, 7/3 or 8/3 tiles. But in Tiled I get only 2 or 3. If Tiled can do this, please teach me.

  • WCF service and security

    - by Gaz83
    Been building a WP7 app and now I need it to communicate to a WCF service I made to make changes to an SQL database. I am a little concerned about security as the user name and password for accessing the SQL database is in the App.Config. I have read in places that you can encrypt the user name and password in the config file. As the username and password is never exposed to the clients connected to the WCF service, would security in my situation be much of a problem? Just in case anyone suggests a method of security, I do not have SSL on my web server.

  • How do you develop web applications? [closed]

    - by ck3g
    How do you and/or your team develop your web applications? Language, framework or platform doesn't matter. I would like to know about the structure of your environment. For example: Using IDE on workstation and project files on remote host accessing via sftp. Files are saved instantly on remote host; All files are local and are uploaded on remote host during saving; Files are local, web server is running on local computer and is tested at local host. etc. You could write down also about the benefits of your approach, this will be useful for me. Thanks upd: Here must be a question and here it is: which is the best approach by your opinion?

  • Using WebStorm for Razor Syntax MVC

    - by Jay Stevens
    I am building a lot of client-side heavy SPA-like apps with VS2010 and MVC3/4. VS2010 Javascript/HTML/CSS editing (mostly javascript) is interminably slow and sluggish. I'd love to use something like JetBrains' WebStorm to edit my .CSHTML files (with embedded javascript, etc. because I am using RAzor to pop in URL names, etc.) WebStorm seems to have all of the things I want.. better language recognition ("intellisense") and the ability to integrate additional outside libraries into this (I'm using Kendo), etc. Is this possible? How do you get WebStorm to recognize the @"" invoked Razor language inserts? Any help or suggestions would be appreciated.

  • Great Presentation to the Israel Dot Net Developers User Group (IDNDUG)

    I continue to be impressed with the quality of .NET Developers in Israel.. we had a full house last night for a 2+ hour presentation on building business applications with Silverlight and RIA Services.   The audience was very engaged and had lots of good, relevant questions which created a really good conversation.    Check out the slides and demo. I started off by demoing the Right-to-Left text support for Hebrew that is baked in as part of Silverlight 4.   ...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.

  • Advice on starting a new job

    - by Sisiutl
    In a week I will start a new job at a manufacturing company managing the development of a new eCommerce site. The company scores about a 3 on the "Joel" test. I will inherit 3 programmers who developed the company web site and do general IT programming. I have the grey hair and credentials to have their initial respect but I'm an engineer, not a manager. I'm looking for practical advise - particularly for the first 90 days - on how to establish myself, keep the team together, and move forward.

  • Online training modules / programs for best software engineering practices?

    - by Steve
    We're taking over a team in a foreign country and the programming standards there aren't up to par with US standards. Folks there lack the formal training and basic understanding of computing concepts of databases, how computers work, what good software engineering practices are. Short of sending these ppl to college again, are there good online courses available that we can enroll them into so that they can upgrade their skills? I am specifically looking for online training courses, but recommendations for books are also welcome. This is language-agnostic.

  • *Code owner* system: is it an efficient way?

    - by sergzach
    There is a new developer in our team. An agile methodology is in use at our company. But the developer has another experience: he considers that particular parts of the code must be assigned to particular developers. So if one developer had created a program procedure or module it would be considered normal that all changes of the procedure/module would be made by him only. On the plus side, supposedly with the proposed approach we save common development time, because each developer knows his part of the code well and makes fixes fast. The downside is that developers don't know the system entirely. Do you think the approach will work well for a medium size system (development of a social network site)?

  • Week 17: Specialization Flashback

    - by sandra.haan
    Remember when E.T. phoned home and Ferris had a day off? Or when Michael Jackson did the moonwalk and Madonna was the Material Girl? That's what we call an 80's flashback. Remember when we offered you 11 specializations? That's what we call a Specialization flashback considering we now have over 35 Specializations available. A lot has changed since we rolled-out OPN Specialized last year. Listen in as Nick Kritikos talks about the latest specializations available. Now get out of that DeLorean and take a look at the Specialization Guide to determine how your company can get Specialized. Until next time, The OPN Communications Team

  • Are libc versions tied to kernel versions?

    - by mathematician1975
    After reading the answers to my previous question I have come to the conclusion that an answer to the following question is what I was actually looking for: Does a particular version of the kernel require a particular version of libc to run properly? Basically my problem stems from building an application on my 12.04 ubuntu and trying to run it on 8.04. I have since learned from this and other stackexchange forums that it is backward compatibility of libc that causes these problems. Therefore what I am perhaps naively trying to do is build the same version of libc that exists on my target and then link against that on my host when I build the application. Then in an ideal world when I copy this to the host, having been linked to the "correct" libc it should work (in my head at least). I have been totally unable to find a way to install an older libc on my system, and wondered if each version is tightly bound to a kernel version, hence the above question.

  • Is "no installation" software a good thing?

    - by Yaron Naveh
    I am building an application that will, hopefully, be used by developers. To be appealing to developers I want it to be lightweight, small in size, and with no installation (e.g. xcopy). I trust more an application without installation to not put garbage in my registry, to be lightweight etc. My friend thinks the opposite: An installer puts shortcuts on the desktop / menu for me, it ensures cleanup via the uninstaller, and seems more official. I'm curious - what is everyone's take on this?

  • Multi-lingual error messages and error numbers

    - by Jon Hopkins
    So we're looking at the possibility of porting our software to support multiple languages and one of the areas we're going to have to deal with is error messages and other notifications. These obviously have to be reported to the users in their own language. Our team (largely) only speak English and even if we were all multi-lingual we're looking at selling to a wide range of countries and could never expect to have a reasonable number of people speaking all languages (we're a small company). The obvious way to get round the language issue when errors or other messages we may get asked about which are being reported is error numbers which would be consistent across language. While these are going to exist in the backend (if only as key on the error message), I'd really rather not throw them at users if we don't have to but I don't have any other solution. Anyone have any useful suggestions for alternatives?

  • Design patterns and multiple programming languages

    - by Eduard Florinescu
    I am referring here to the design patterns found in the GOF book. First, how I see it, there are a few peculiarities to design pattern and knowing multiple languages, for example in Java you really need a singleton but in Python you can do without it you write a module, I saw somewhere a wiki trying to write all GOF patterns for JavaScript and all the entries were empty, I guess because it might be a daunting task to do that adaptation. If there is someone who is using design patterns and is programming multiple languages supporting the OOP paradigm and can give me a hint on how should I approach design patterns. An approach that might help me in all languages I use(Java, JavaScript, Python, Ruby): Can I write good application without knowing exactly the GOF design patterns or I might need just some of them which might be crucial and if yes which one, are there alternatives to GOF for specific languages, and should a programmer or a team make their own design patterns set?

  • How can a student programmer improve his teamwork skill?

    - by xiao
    I am a student right now. Recently, I am working in a project as a leader with three other students. Due to the lack of experience, our project is progressing slowly and our members are frustrated. They do not feel sense of accomplishment in the project. I am pressured and frustrated, too. But as a team leader, I think I need to push them. But I do not know how to do. Do I help them solve coding problem or just encouragement? But if I pay too much attention on it, it would slow down my own progress. It is a not technical question, but it is very common in software development. I hope veteran programmers would give me some suggestions. Thanks!

  • C# return variables

    - by pb01
    In a debate regarding return variables, some members of the team prefer a method to return the result directly to the caller, whereas others prefer to declare a return variable that is then returned to the caller (see code examples below) The argument for the latter is that it allows a developer that is debugging the code to find the return value of the method before it returns to the caller thereby making the code easier to understand: This is especially true where method calls are daisy-chained. Are there any guidelines as to which is the most efficient and/or are there any other reasons why we should adopt one style over another? Thanks private bool Is2(int a) { return a == 2; } private bool Is3(int a) { var result = a == 3; return result; }

  • detecting when you are going to reach your hit limit for Google Analytics free account

    - by crmpicco
    I am a user of a free Google Analytics account and i'm slightly concerned that I may be approaching the 10,000,000 hit (Pageviews, Events etc) per month. Google state in their documentation: These limits apply to the Web Property / Property / Tracking ID. 10 million hits per month per property If you go over this limit, the Google Analytics team might contact you and ask you upgrade to Premium or implement client sampling to reduce the amount of data being sent to Google Analytics. However, I note that there is nothing to say that you can review or check up on your current usage for the month. I have administrator access to the Google Analytics account, but I see no feature that lets me check up on my monthly usage. I don't know if Google offer this, either by means of the admin interface or via their support channels - but it would certainly be a useful feature. Is there anyway for a free GA user to obtain this information?

  • Should my colleagues review each others code from source control system?

    - by Daniel Excinsky
    Hi everybody. So that's my story: one of my colleagues uses to review all the code, hosted to revision system. I'm not speaking about adequate review of changes in parts that he belongs to. He watches the code file to file, line to line. Every new file and every modified. I feel just like being spied on! My guess is that if code was already hosted to control system, you should trust it as workable at least. My question is, maybe I'm just too paranoiac and practice of reviewing each others code is good? P.S: We're team of only three developers, and I fear that if there will be more of us, colleague just won't have time to review all the the code we'll write.

  • Should all new web projects build their backend based on xml/json result sets?

    - by Blankman
    If you were building a new Saas project, would it make sense to start with all of the backend services returning xml/json? Because these days you need to build for both the web and mobile devices, and having a backend that is build from the start to return xml and json, you are ready to go mobile (all services have the business logic, so you won't be repeating anything). Now the web would be MVC, so the controller would just be routing the request to your service backend, and converting the json or xml to html. The obviousl downside is that you have to build a backend, and then another web project that calls your backend. But this also goes to you favor as it forces you to seperate your concerns, and not leak business logic in your controller/view layer. Thoughts?

  • Highlights from the Oracle Customer Experience Summit @ OpenWorld

    - by Kathryn Perry
    A guest post by David Vap, Group Vice President, Oracle Applications Product Development The Oracle Customer Experience Summit was the first-ever event covering the full breadth of Oracle's CX portfolio -- Marketing, Sales, Commerce, and Service. The purpose of the Summit was to articulate the customer experience imperative and to showcase the suite of Oracle products that can help our customers create the best possible customer experience. This topic has always been a very important one, but now that there are so many alternative companies to do business with and because people have such public ways to voice their displeasure, it's necessary for vendors to have multiple listening posts in place to gauge consumer sentiment. They need to know what is going on in real time and be able to react quickly to turn negative situations into positive ones. Those can then be shared in a social manner to enhance the brand and turn the customer into a repeat customer. The Summit was focused on Oracle's portfolio of products and entirely dedicated to customers who are committed to building great customer experiences within their businesses. Rather than DBAs, the attendees were business people looking to collaborate with other like-minded experts and find out how Oracle can help in terms of technology, best practices, and expertise. The event was at the Westin St. Francis Hotel in San Francisco as part of Oracle OpenWorld. We had eight hundred people attend, which was great for the first year. Next year, there's no doubt in my mind, we can raise that number to 5,000. Alignment and Logic Oracle's Customer Experience portfolio is made up of a combination of acquired and organic products owned by many people who are new to Oracle. We include homegrown Fusion CRM, as well as RightNow, Inquira, OPA, Vitrue, ATG, Endeca, and many others. The attendees knew of the acquisitions, so naturally they wanted to see how the products all fit together and hear the logic behind the portfolio. To tell them about our alignment, we needed to be aligned. To accomplish that, a cross functional team at Oracle agreed on the messaging so that every single Oracle presenter could cover the big picture before going deep into a product or topic. Talking about the full suite of products in one session produced overflow value for other products. And even though this internal coordination was a huge effort, everyone saw the value for our customers and for our long-term cooperation and success. Keynotes, Workshops, and Tents of Innovation We scored by having Seth Godin as our keynote speaker ? always provocative and popular. The opening keynote was a session orchestrated by Mark Hurd, Anthony Lye, and me. Mark set the stage by giving real-world examples of bad customer experiences, Anthony clearly articulated the business imperative for addressing these experiences, and I brought it all to life by taking the audience around the Customer Lifecycle and showing demos and videos, with partners included at each of the stops around the lifecycle. Brian Curran, a VP for RightNow Product Strategy, presented a session that was in high demand called The Economics of Customer Experience. People loved hearing how to build a business case and justify the cost of building a better customer experience. John Kembel, another VP for RightNow Product Strategy, held a workshop that customers raved about. It was based on the journey mapping methodology he created, which is a way to talk to customers about where they want to make improvements to their customers' experiences. He divided the audience into groups led by facilitators. Each person had the opportunity to engage with experts and peers and construct some real takeaways. From left to right: Brian Curran, John Kembel, Seth Godin, and George Kembel The conference hotel was across from Union Square so we used that space to set up Innovation Tents. During the day we served lunch in the tents and partners showed their different innovative ideas. It was very interesting to see all the technologies and advancements. It also gave people a place to mix and mingle and to think about the fringe of where we could all take these ideas. Product Portfolio Plus Thought Leadership Of course there is always room for improvement, but the feedback on the format of the conference was positive. Ninety percent of the sessions had either a partner or a customer teamed with an Oracle presenter. The presentations weren't dry, one-way information dumps, but more interactive. I just followed up with a CEO who attended the conference with his Head of Marketing. He told me that they are using John Kembel's journey mapping methodology across the organization to pull people together. This sort of thought leadership in these highly competitive areas gives Oracle permission to engage around the technology. We have to differentiate ourselves and it's harder to do on the product side because everyone looks the same on paper. But on thought leadership ? we can, and did, take some really big steps.
