  • Legal question.

    - by Kjow
    Hi all, a question bounces in my head from some time. Copyright laws are different by nation to nation, but generally which is the border line to break a copyright? Suppose to make a game that is very similar to an other come out in the past, e.g. a Pacman clone or a Space Invaders clone, but nothing from original titles are grabbed and maybe they're not made in 2d, but in 3d. The titles aren't "Pacman clone - the return" or "Space Invaders - they did it again", and not also "Pocman" or "Space Evaders" (maybe this last could be fun for some "creative financers" that need to escape from earth :D). Finally suppose to call these some thing like "Popcorn, fruit and ghosts" (or the acronym: "PFG") and "Kill all enemy" (or the acronym: "KAE"). In this case (not grab- all self-made) and no references to original titles, but with a game that feels very similar to "ispiration ones"... they could be sold to somewhere like "Valve's Steam"? Regards, Kjow

  • Do I need to match hardware on a Mac to my PC to get the same user experience?

    - by Darth
    I've been playing around with the thought of moving from a PC to a Mac. if you don't want to read this, skip to the "upgrade options" My current setup Most of my time I spent moving back and forth between Linux and Windows. During the last upgrade to Vista, I got myself pc with Core 2 Quad, 8GB of RAM and GeForce 9800GTX+. Currently I'm running dual boot between Ubuntu 10.04 and Windows Vista x64. Most of my work, around 80%, I can do on Ubuntu, which is mostly Ruby/Java programming. If that was all I needed, Ubuntu would be really great. However, I also do quite a lot of Photography and Design, which forces me to use Adobe software (not only Photoshop). I also work with Wacom Intuos4 tablet, which doesn't really have great support on Linux machines. I've tried virtualization both ways (Linux in Win and Win in Linux), but neither was anywhere near satisfying. These are those of many many reasons I want to move to OS X. Upgrade options This is how I see my upgrade options: Mac Mini - cheapest solution, but worst performance iMac - more expensive, better performing with second LCD for free Mac Pro - could match my current PC performance, currently outside of the price range When I compare the Mac hardware vs my current PC, it will be always worse, unless I decide to pump in a lot of money. The question that comes to my head, do I need to match my current PC hardware to get the same user experience with a Mac? If I look at it from the Vista point of view, 2GB RAM is as low as it gets, 4GB is usable ... and the 8GB runs very smoothly. PC HW != Mac HW? If I bought the Mac Mini for roughly the same price I paid for my PC (Core 2 Quad with 8GB RAM), I'd get Core 2 Duo with 4GB RAM. But I don't want to run Vista on it, so I can't compare the hardware directly. Say that I want to do the same things on the Mac Mini as I do on my PC, eg. open up 50 tabs in Google Chrome and start working with a large PSD in Photoshop (couple hundred MB), would running on Mac OS X compensate for the lower hardware performance? My point is, that if I'm about to upgrade, I wouldn't like to upgrade to hardware that runs a lot slower. Good analogy for this is Vista vs Ubuntu, where you can run Ubuntu smoothly on a low end laptop, but in Vista, you'd be happy to open a browser. Does the same principle apply to OS X?

  • Avoid Memory Leaks in SharePoint2010 Development

    - by ybbest
    When you develop SharePoint solution using code, you need to Dispose SPWeb appropriately to avoid memory Leaks. The general guideline for this are: Dispose Not to dispose OpenWebEnumerating Webs or AllWebs ParentWebRootWeb SPWeb from SPContext There are more rules than the one list above and as a smart SharePoint developer, you do not have to memories all the rules .There is a tool called SharePoint Dispose Checker which can help you to find potential memory leak. To use SPDisposeChecker in you solution, you need to download the tool from MSDN Code Gallery and install it in your development machine as follow. 1. Run the installer with elevated privilege. 2. Accept the agreement and click next. 3. Select those two options and click next. 4. Select Everyone and click Next. 5. Go to Toolsà SharePoint Dispose Check to Configure the SPDisposeCheck. 6. You can change the Treat problems as Errors to Warnings. 7. after clicking Save, you are all set to use the tool.Recompile my project , I can get the result below. References: SharePoint 2007/2010 “Do Not Dispose Guidance” + SPDisposeCheck

  • Can LittleBigPlanet2's engine be used for other ?

    - by Bill
    LittleBigPlanet2 just came out. I've worked with the original LBP level editor a bit and really enjoyed it. I've read that LBP2's featureset in the game is much richer; is it possible to use these advanced features to create different sorts of game other than just a regular platformer? I imagine that something along the lines of a Breakout clone would definitely be manageable, but I'm interested in hearing more about the capabilities of the platform.

  • Get Python to raise MemoryError instead of eating all my disk space

    - by asmeurer
    If I run a Python program with a memory leak, I would normally expect the program to eventually die with MemoryError. But instead, what happens is that all the virtual memory is used until my disk runs out of space. I am running Mac OS X 10.8 on a retina MacBook Pro. My computer generally has between 10GB to 20GB free. Mac OS X is smart enough to not die completely when the disk runs out of space (rather, it gives me a dialog letting me force quit my GUI programs). Is there a way to make Python just die when it runs out of real memory, or some reasonable amount of virtual memory? This is what happens on Linux, as far as I can tell. I guess Mac OS X is more generous than Linux with virtual memory (the fact that I have an SSD might be part of this; I don't know just how smart OS X is with this stuff). Maybe there's a way to tell the Mac OS X kernel to never use so much virtual memory that leaves less than, say, 5 GB free on the hard drive?

  • Silverlight 4 and Windows Phone Development

    - by Bobby Diaz
    There were a lot of announcements made during the keynote at MIX10 today, most notable were the releases of Silverlight 4 RC, Silverlight 4 Tools for Visual Studio 2010, Expression Blend 4 Beta and the Windows Phone 7 Developer Tools.  I was glad to see that developers will be able to use Silverlight to create awesome applications for Windows Phone 7 so we can reuse our WPF and Silverlight skills to target mobile devices! With so much information coming out of this conference, I wanted to be sure to save a list of links that I can quickly reference as I learn about these exciting new technologies: Silverlight 4 A guide to what has changed in the Silverlight 4 RC Silverlight 4 Beta – A guide to the new features WCF RIA Services Silverlight 4 Information Silverlight Toolkit  March 2010 Release  was still showing Nov09 at time of posting… Windows Phone 7 Getting Started with Silverlight and Windows Phone 7 Development Building your first Silverlight for Windows Phone Application Silverlight for Windows Phone Windows Phone for Developers Developing for Windows Phone 7 Series Whew, and that’s just from day 1!  Can’t wait to see what else comes out tomorrow.  Hopefully these links will give you a good starting point for Silverlight 4 and Windows Phone 7 information.

  • finite state machine used in mario like platform game

    - by juakob
    I dont understand how to use a finite state machine with the entity controlled by the player. For example i have a mario(2d platform) i can jump,run,walk,take damage,swim,etc so my first thought was to use this actions as states. But what happen when you are running when you take damage? or jumping taking damage and shooting at the same time? I just want to add functionalities(actions) to the player in a clean way(not using ifs for all the actions in the entity update)

  • PHP remote development workflow: git, symfony and hudson

    - by user2022
    I'm looking to develop a website and all the work will be done remotely (no local dev server). The reason for this is that my shared hosting company a2hosting has a specific configuration (symfony,mysql,git) that I don't want to spend time duplicating when I can just ssh and develop remotely or through netbeans remote editing features. My question is how can I use git to separate my site into three areas: live, staging and dev. Here's my initial thought: public_html (live site and git repo) testing: a mirror of the site used for visual tests (full git repo) dev/ticket# : git branches of public_html used for features and bug fixes (full git repo) Version Control with git: Initial setup: cd public_html git init git add * git commit -m ‘initial commit of the site’ cd .. git clone public_html testing mkdir dev Development: cd /dev git clone ../testing ticket# all work is done in ./dev/ticket#, then visit www.domain.com/dev/ticket# to visually test make granular commits as necessary until dev is done git push origin master:ticket# if the above fails: merge latest testing state into current dev work: git merge origin/master then try the push again mark ticket# as ready for integration integration and deployment process: cd ../../testing git merge ticket# -m "integration test for ticket# --no-ff (check for conflicts ) run hudson tests visit www.domain.com/testing for visual test if all tests pass: if this ticket marks the end of a big dev sprint: make a snapshot with git tag git push --tags origin else git push origin cd ../public_html git checkout -f (live site should have the latest dev from ticket#) else: revert the merge: git checkout master~1; git commit -m "reverting ticket#" update ticket# that testing failed with the failure details Snapshots: Each major deployment sprint should have a standard name and should be tracked. Method: git tag Naming convention: TBD Reverting site to previous state If something goes wrong, then revert to previous snapshot and debug the issue in dev with a new ticket#. Once the bug is fixed, follow the deployment process again. My questions: Does this workflow make sense, if not, any recommendations Is my approach for reverting correct or is there a better way to say 'revert to before x commit'

  • How to achieve highly accurate car physics such as Liveforspeed?

    - by Kim Jong Woo
    Liveforspeed is a racing simulator, there is amazing amount of realistic physics. for example, tires get warm, tire actually deforms when you turn corners. You need to play this game with a mouse at the minimum because it almost drives like the real thing. Anyhow, how does one achieve that level of physics simulation? Are there off-the-shelf solutions out there? If not, how does one start with simulating real world physics as close as possible. I would love to be able to work on an opensource car physics focused game. Imagine, more passionate developers, it could keep things going.

  • Step by Step screencasts to do Behavior Driven Development on WCF and UI using xUnit

    - by oazabir
    I am trying to encourage my team to get into Behavior Driven Development (BDD). So, I made two quick video tutorials to show how BDD can be done from early requirement collection stage to late integration tests. It explains breaking user stories into behaviors, and then developers and test engineers taking the behavior specs and writing a WCF service and unit test for it, in parallel, and then eventually integrating the WCF service and doing the integration tests. It introduces how mocking is done using the Moq library. Moreover, it shows a way how you can write test once and do both unit and integration tests at the flip of a config setting. Watch the screencast here: Doing BDD with xUnit, Subspec and on a WCF Service  Warning: you might hear some noise in the audio in some places. Something wrong with audio bit rate. I suggest you let the video download for a while and then play it. If you still get noise, go back couple of seconds earlier and then resume play. It eliminates the noise.  The next video tutorial is about doing BDD to do automated UI tests. It shows how test engineers can take behaviors and then write tests that tests a prototype UI in isolation (just like Service Contract) in order to ensure the prototype conforms to the expected behaviors, while developers can write the real code and build the real product in parallel. When the real stuff is done, the same test can test the real stuff and ensure the agreed behaviors are satisfied. I have used WatiN to automate UI and test UI for expected behaviors. Doing BDD with xUnit and WatiN on a ASP.NET webform Hope you like it!

  • Microsoft MVP Award &ndash; Data Platform Development

    - by Dane Morgridge
    For those who don't already know, yesterday I received my first Microsoft MVP Award in Data Platform Development.  With less than 5,000 MVPs in the world overall and about 20 in the Data Platform category, saying I am honored would be an understatement.  From the first time I spoke at a code camp, I was totally hooked and have had a blast travelling around the east coast speaking at code camps and users groups.  I'd like to take the time to thank Dani Diaz (@danidiaz) for the nomination and everyone who supported me, especially my wife Lisa for letting me travel and speak as much as I have and putting up with me for late nights and such.  Roska Digital, my employer, also deserves a shout out for supporting me and giving me the necessary time off to get to speaking engagements.  With any luck, the next year will be at least as fun if not more than the last one has.  I hope to see you at a code camp or user group meeting soon! I would also like to send a congratulations to the other new Philly Area MVPs: John Angelini (@johnangelini) & Ned Ames (@nedames) You can find out more about the Microsoft MVP Award at https://mvp.support.microsoft.com/

  • Windows Azure Database (SQL Azure) Development Tip

    - by BuckWoody
    When you create something in the cloud, it's real, and you're charged for it. There are free offerings, and you even get free resources with your Microsoft Developer Network (MSDN) subscription, but there are limits within those. Creating a 1 GB database - even with nothing in it - is a 1 GB Database. If you create it, drop it, and create it again 2 minutes later, that's 2 GB of space you've used for the month. Wait - how do I develop in this kind of situation? With Windows Azure, you can simply install the free Software Development Kit (SDK) and develop your entire application for free - you need never even log in to Windows Azure to code. Once you're done, you simply deploy the app and you start making money from the application as you're paying for it. Windows Azure Databases (The Artist Formerly Known As SQL Azure) is a bit different. It's not emulated in the SDK - because it doesn't have to be. It's just SQL Server, with some differences in feature set. To develop in this environment, you can use SQL Server, any edition. Be aware of the feature differences, of course, but just develop away - even in the free "Express" or LocalDB flavors - and then right-click in SQL Server Management Studio to script objects. Script the database, but change the "Advanced" selection to the Engine Type of "SQL Azure". Bing. Although most all T-SQL ports directly, one thing to keep in mind is that you need a Clustered Index on every table. Often the Primary Key (PK) is a good choice for that.

  • Is unit testing development or testing?

    - by Rubio
    I had a discussion with a testing manager about the role of unit and integration testing. She requested that developers report what they have unit and integration tested and how. My perspective is that unit and integration testing are part of the development process, not the testing process. Beyond semantics what I mean is that unit and integration tests should not be included in the testing reports and systems testers should not be concerned about them. My reasoning is based on two things. Unit and integration tests are planned and performed against an interface and a contract, always. Regardless of whether you use formalized contracts you still test what e.g. a method is supposed to do, i.e. a contract. In integration testing you test the interface between two distinct modules. The interface and the contract determine when the test passes. But you always test a limited part of the whole system. Systems testing on the other hand is planned and performed against the system specifications. The spec determines when the test passes. I don't see any value in communicating the breadth and depth of unit and integration tests to the (systems) tester. Suppose I write a report that lists what kind of unit tests are performed on a particular business layer class. What is he/she supposed to take away from that? Judging what should and shouldn't be tested from that is a false conclusion because the system may still not function the way the specs require even though all unit and integration tests pass. This might seem like useless academic discussion but if you work in a strictly formal environment as I do, it's actually important in determining how we do things. Anyway, am I totally wrong? (Sorry for the long post.)

  • Android threads trouble wrapping my head around design

    - by semajhan
    I am having trouble wrapping my head around game design. On the android platform, I have an activity and set its content view with a custom surface view. The custom surface view acts as my panel and I create instances of all classes and do all the drawing and calculation in there. Question: Should I instead create the instances of other classes in my activity? Now I create a custom thread class that handles the game loop. Question: How do I use this one class in all my activities? Or do I have to create a separate instance of the extended thread class each time? In my previous game, I had multiple levels that had to create an instance of the thread class and in the thread class I had to set constructor methods for each separate level and in the loop use a switch statement to check which level it needs to render and update. Sorry if that sounds confusing. I just want to know if the method I am using is inefficient (which it probably is) and how to go about designing it the correct way. I have read many tutorials out there and I am still having lots of trouble with this particular topic. Maybe a link to a some tutorials that explain this? Thanks.

  • difference between Casini [IIS express] and VS Development server or Expression web

    - by anirudha
    MVC3 project can be run within Expression web and Visual studio as opened like a website not a project. they work same even if you open blogengine.net project in VS they take a time when you have more theme but expression web debug them in a second. well because theme design not matter for code. Expression web is a good because they save time for compile the code. even changes we make a little in design nothing in backend code.   i found a little difference between Casini and VS development server that if image putted in wrong way like <img src=”//img.png”/> instead of <img src=”/img.png”/> the error we make // instead of / that’s not worked in Expression web or Visual studio debugging but in Cassini it’s work fine.   Well i found that debug Blogengine.net in Expression web is a great thing because in VS they take a time like a minute to debug when you trying to debug first time. Expression Web save a time when we design themes within them and that’s much good option because web is also maked for design.   Well if you want to debug application faster then use casini but Expression web debugging is a good option when they take a long time to debug in Visual studio and EW debug them in a seconds.

  • Enable FTP on OS X 10.8 Mountain Lion Server

    - by Oleg Trakhman
    There is a LAN comprising several mac machines (iMac, Mac Pro, macbook etc.), Airport Express router and Mac Mini Server running OS X Server 10.8 (Mountain Lion Server). I need to share a folder on Mac Mini Server by FTP. What did I try so far: Made special partition for FTP Access, call it "Reports" So shared folder would be "/Volumes/Reports" Gave access every user and group in system, and also enabled guest access. I checked posix acl, which is "rwxrwxrwx", I checked sharing settings in "Preferences.app" and "Server.app" Checked that users have access to FTP service Enabled FTP in Server.app I tried access to shared folder (by FTP): via Cyberduck via Finder via shell: ftp server.local And what I got: $ ftp [email protected] Trying 10.0.2.2... Connected to server.local. 220 10.0.2.2 FTP server (tnftpd 20100324+GSSAPI) ready. 331 User ftpuser accepted, provide password. Password: 530 User ftpuser may not use FTP. and $ ftp [email protected] Trying 10.0.2.2... Connected to server.local. 220 10.0.2.2 FTP server (tnftpd 20100324+GSSAPI) ready. 331 User admin accepted, provide password.

  • Feasability of mobile 2D multiplayer RPG game with interactive bitmap background

    - by user2827214
    I'm looking to develop a 2D multiplayer RPG game for Android, with a bird's eye view similar to that of zelda/pokemon. The game is very simple in all ways since my intent is for thousands of players to occupy the same world which I imagine requires good performance. However, I am unsure about the performance requirements of two properties: the tile map that is used as a background is dynamic (interactive). For example, a player steps in the water, and the water turns black. Every tile in the game does this. the tile map is the same object used for all players, but it is displayed differently on each user's mobile device, even though the players exist in the same world. For example, the water that turned black is displayed as red on all other players' screens. I have knowledge of java, but almost none regarding game dev. tools. Is there a best process for these requirements? Should I develop in pure java, or use some tool like Slick2D etc.? How performance intensive are these properties, if even possible? Edit: There are no collisions in the game or difficult animations, I am imagining simply changing the colors of the tiles (like in the examples), and a client-server architecture

  • Development teams do not scale

    - by Matt Watson
    Recently I have been thinking about how development teams don't scale very well. The bigger a team and the product get, the more time the team spends fixing software bugs. This means they spend more time doing troubleshooting and debugging as the grow. The problem is that since developers don't typically have access to production servers, there is a bottleneck in the process when doing production troubleshooting.For a team that has 10 developers, I would guess than 0-2 of them have access to production servers. If that team grows to 20 people, it is probably the same 0-2 people that have production access still. This means that those 2 key people are a bottleneck and the team does not scale correctly as you add more resources. All those new developers want is to help track down and fix software bugs, but they don't have the visibility to do it. So they end up being less productive and frustrated because they really want to fix the problems. The people who do have production access end up spending too much of their time doing troubleshooting instead of working on new projects.The solution is to remove the bottlenecks and get those people working on more important tasks. Stackify can solve this problem by giving all the developers read only access to production servers. This allows them to access the information they need to do troubleshooting on their own.

  • Is the development of CLI apps considered "backward"?

    - by user61852
    I am a DBA fledgling with a lot of experience in programming. I have developed several CLI, non interactive apps that solve some daily repetitive tasks or eliminate the human error from more complex albeit not so daily tasks. These tools are now part of our tool box. I find CLI apps are great because you can include them in an automated workflow. Also the Unix philosophy of doing a single thing but doing it well, and letting the output of a process be the input of another, is a great way of building a set of tools than would consolidate into an strategic advantage. My boss recently commented that developing CLI tools is "backward", or constitutes a "regression". I told him I disagreed, because most CLI tools that exist now are not legacy but are live projects with improved versions being released all the time. Is this kind of development considered "backwards" in the market? Does it look bad on a rèsumè? I also considered all solutions whether they are web or desktop, should have command line, non-interactive options. Some people consider this a waste of programming resources. Is this goal a worthy one in a software project?

  • any online service and/or application to develop a story line for an adventure game?

    - by Gajet
    I with a bunch of friend were talking about an adventure game. there will be too many possibilities in the game and the player can pick from wide varity of choices at each stage to do somthing. there will be consequences for each decision and they may or may not end the story. the result would be somthing like (picture from flashforward series S01E17)or if any of you watched hereos season 1 there is also similar time lines represented as strings in isaac mandez workshop. sorry for bad quality examples but right now I can't think of any better one. do you know any website or application which we can use to create the timeline? these features the least required ones: the ability to represent events as boxes. the ability to connect distant events to each other. the ability to move events on a scene freely the ability to expand the scene easily there should be some color options for the lines representing connections between events easily shareing the idea with one another it's much more better to have a WYSIWYG editor easily explore in the large scene of events in the end if you know any application which could let me create a board just like the one in my sample picture and share it whith other freinds it could help us a lot.

  • Clean Code Development & Flexible work environment - MSCC 26.10.2013

    Finally, some spare time to summarize my impressions and experiences of the recent meetup of Mauritius Software Craftsmanship Community. I already posted my comment on the event and on our social media networks: Professional - It's getting better with our meetups and I really appreciated that 'seniors' and 'juniors' were present today. Despite running a little bit out of time it was really great to see more students coming to the gathering. This time we changed location for our Saturday meetup and it worked out very well. A big thank you to Ebene Accelerator, namely Mrs Poonum, for the ability to use their meeting rooms for our community get-together. Already some weeks ago I had a very pleasant conversation with her about the MSCC aims, 'mission' and how we organise things. Additionally, I think that an environment like the Ebene Accelerator is a good choice as it acts as an incubator for young developers and start-ups. Reactions from other craftsmen Before I put my thoughts about our recent meeting down, I'd like to mention and cross-link to some of the other craftsmen that were present: "MSCC meet up is a massive knowledge gaining strategies for students, future entrepreneurs, or for geeks all around. Knowledge sharing becomes a fun. For those who have not been able to made it do subscribe on our MSCC meet up group at meetup.com." -- Nitin on Learning is fun with #MSCC #Ebene Accelerator "We then talked about the IT industry in Mauritius, salary issues in various field like system administration, software development etc. We analysed the reasons why people tend to hop from one company to another. That was a fun debate." -- Ish on MSCC meetup - Gang of Geeks "Flexible Learning Environment was quite interesting since these lines struck cords : "You're not a secretary....9 to 5 shouldn't suit you"....This allowed reflection...deep reflection....especially regarding the local mindset...which should be changed in a way which would promote creativity rather than choking it till death..." -- Yannick on 2nd MSCC Monthly Meet-up And others on Facebook... ;-) Visual impressions are available on our Meetup event page. More first time attendees We great pleasure I noticed that we have once again more first time visitors. A quick overlook showed that we had a majority of UoM students in first, second or last year. Some of them are already participating in the UoM Computer Club or are nominated as members of the Microsoft Student Partner (MSP) programme. Personally, I really appreciate the fact that the MSCC is able to gather such a broad audience. And as I wrote initially, the MSCC is technology-agnostic; we want IT people from any segment of this business. Of course, students which are about to delve into the 'real world' of working are highly welcome, and I hope that they might get one or other glimpse of experience or advice from employees. Sticking to the schedule? No, not really... And honestly, it was a good choice to go a little bit of the beaten tracks. I mean, yes we have a 'rough' agenda of topics that we would like to talk about or having a presentation about. But we keep it 'agile'. Due to the high number of new faces, we initiated another quick round of introductions and I gave a really brief overview of the MSCC. Next, we started to reflect on the Clean Code Developer (CCD) - Red Grade which we introduced on the last meetup. Nirvan was the lucky one and he did a good job on summarizing the various abbreviations of the first level of being a CCD. Actually, more interesting, we exchanged experience about the principles and practices of Red Grade, and it was very informative to get to know that Yann actually 'interviewed' a couple of friends, other students, local guys working in IT companies as well as some IT friends from India in order to counter-check on what he learned first-hand about Clean Code. Currently, he is reading the book of Robert C. Martin on that topic and I'm looking forward to his review soon. More output generates more input What seems to be like a personal mantra is working out pretty well for me since the beginning of this year. Being more active on social media networks, writing more article on my blog, starting the Mauritius Software Craftsmanship Community, and contributing more to other online communities has helped me to receive more project requests, job offers and possibilities to expand my business at IOS Indian Ocean Software Ltd. Actually, it is not a coincidence that one of the questions new craftsmen should answer during registration asks about having a personal blog. Whether you are just curious about IT, right in the middle of your Computer Studies, or already working in software development or system administration since a while you should consider to advertise and market yourself online. Easiest way to resolve this are to have online profiles on professional social media networks like LinkedIn, Xing, Twitter, and Google+ (no Facebook should be considered for private only), and considering to have a personal blog. Why? -- Be yourself, be proud of your work, and let other people know that you're passionate about your profession. Trust me, this is going to open up opportunities you might not have dreamt about... Exchanging ideas about having a professional online presence - MSCC meetup on the 26th October 2013 Furthermore, consider to put your Curriculum Vitae online, too. There are quite a number of service providers like 1ClickCV, Stack Overflow Careers 2.0, etc. which give you the ability to have an up to date CV online. At least put it on your site, next to your personal blog. Similar to what you would be able to see on my site here. Cyber Island Mauritius - are we there? A couple of weeks ago I got a 'cold' message on LinkedIn from someone living in the U.S. asking about the circumstances and conditions of the IT world of Mauritius. He has a great business idea, venture capital and is currently looking for a team of software developers (mainly mobile - iOS) for a new startup here in Mauritius. Since then we exchanged quite some details through private messages and Skype conversations, and I suggested that it might be a good chance to join our meetup through a conference call and see for yourself about potential candidates. During approximately 30 to 40 minutes the brief idea of the new startup was presented - very promising state-of-the-art technology aspects and integration of various public APIs -, and we had a good Q&A session about it. Also thanks to the excellent bandwidth provided by the Ebene Accelerator the video conference between three parties went absolutely well. Clean Code Developer - Orange Grade Hahaha - nice one... Being at the Orange Tower at Ebene and then talking about an Orange Grade as CCD. Well, once again I provided an overview of the principles and practices in that rank of Clean Code, and similar to our last meetup we discussed on the various aspect of each principle, whether someone already got in touch with it during studies or work, and how it could affect their future view on their source code. Following are the principles and practices of Clean Code Developer - Orange Grade: CCD Orange Grade - Principles Single Level of Abstraction (SLA) Single Responsibility Principle (SRP) Separation of Concerns (SoC) Source Code conventions CCD Orange Grade - Practices Issue Tracking Automated Integration Tests Reading, Reading, Reading Reviews Especially the part on reading technical books got some extra attention. We quickly gathered our views on that and came up with a result that ranges between Zero (0) and up to Fifteen (15) book titles per year. Personally, I'm keeping my progress between Six (6) and Eight (8) titles per year, but at least One (1) per quarter of a year. Which is also connected to the fact that I'm participating in the O'Reilly Reader Review Program and have a another benefit to get access to free books only by writing and publishing a review afterwards. We also had a good exchange on the extended topic of 'Reviews' - which to my opinion is abnormal difficult here in Mauritius for various reasons. As far as I can tell from my experience working with Mauritian software developers, either as colleagues, employees or during consulting services there are unfortunately two dominant pattern on that topic: Keeping quiet Running away Honestly, I have no evidence about why these are the two 'solutions' on reviews but that's the situation that I had to face over the last couple of years. Sitting together and talking about problematic issues, tackling down root causes of de-motivational activities and working on general improvements doesn't seem to have a ground within the IT world of Mauritius. Are you a typist or a creative software craftsman? - MSCC meetup on the 26th October 2013 One very good example that we talked about was the fact of 'job hoppers' as you can easily observe it on someone's CV - those people change job every single year; for no obvious reason! Frankly speaking, I wouldn't even consider an IT person like to for an interview. As a company you're investing money and effort into the abilities of your employees. Hiring someone that won't stay for a longer period is out of question. And sorry to say, these kind of IT guys smell fishy about their capabilities and more likely to cause problems than actually produce productive results. One of the reasons why there is a probation period on an employment contract is to give you the liberty to leave as early as possible in case that you don't like your new position. Don't fool yourself or waste other people's time and money by hanging around a full year only to snatch off the bonus payment... Future outlook: Developer's Conference Even though it is not official yet I already mentioned it several times during our weekly Code & Coffee sessions. The MSCC is looking forward to be able to organise or to contribute to an upcoming IT event. Currently, the rough schedule is set for April 2014 but this mainly depends on availability of location(s), a decent time frame for preparations, and the underlying procedures with public bodies to have it approved and so on. As soon as the information about date and location has been fixed there will be a 'Call for Papers' period in order to attract local IT enthusiasts to apply for a session slot and talk about their field of work and their passion in IT. More to come for sure... My resume of the day It was a great gathering and I am very pleased about the fact that we had another 15 craftsmen (plus 2 businessmen on conference call plus 2 young apprentices) in the same room, talking about IT related topics and sharing their experience as employees and students. Personally, I really appreciated the feedback from the students about their current view on their future career, and I really hope that some of them are going to pursue their dreams. Start promoting yourself and it will happen... Looking forward to your blogs! And last but not least our numbers on Meetup and Facebook have been increased as a direct consequence of this meetup. Please, spread the word about the MSCC and get your friends and colleagues to join our official site. The higher the number of craftsmen we have the better chances we have t achieve something great! Thanks!

  • Is the development of CLI apps considered "backwards"?

    - by user61852
    I am a DBA fledgling with a lot of experience in programming. I have developed several CLI, non interactive apps that solve some daily repetitive tasks or eliminate the human error from more complex albeit not so daily tasks. These tools are now part of our tool box. I find CLI apps are great because you can include them in an automated workflow. Also the Unix philosophy of doing a single thing but doing it well, and letting the output of a process be the input of another, is a great way of building a set of tools than would consolidate into an strategic advantage. My boss recently commented that developing CLI tools is "backwards", or constitutes a "regression". I told him I disagreed, because most CLI tools that exist now are not legacy but are live projects with improved versions being released all the time. Is this kind of development considered "backwards" in the market? Does it look bad on a rèsumè? I also considered all solutions whether they are web or desktop, should have command line, non-interactive options. Some people consider this a waste of programming resources. Is this goal a worthy one in a software project?

This latest release of the Java Platform continues to improve upon the significant advances made in the JDK 8 release with new features, security and performance optimizations. These include: new enterprise-focused administration features available in Oracle Java SE Advanced; products offering greater control of Java version compatibility; security updates; and a very useful new feature, the MSI compatible installer. Download Release Notes Java SE 8 Documentation New tools, features and enhancements highlighted from JDK 8 Update 20 are: Advanced Management Console The Java Advanced Management Console 1.0 (AMC) is available for use with the Oracle Java SE Advanced products. AMC employs the Deployment Rule Set (DRS) security feature, along with other functionality, to give system administrators greater and easier control in managing Java version compatibility and security updates for desktops within their enterprise and for ISVs with Java-based applications and solutions. MSI Enterprise JRE Installer Available for Windows 64 and 32 bit systems in the Oracle Java SE Advanced products, the MSI compatible installer enables system administrators to provide automated, consistent installation of the JRE across all desktops in the enterprise, free of user interaction requirements. Performance: String de-duplication resulting in a reduced footprint Improved support in G1 Garbage Collection for long running apps. A new 'force' feature in DRS (Deployment Rule Set) which allows system administrators to specify the JRE with which an applet or Java Web Start application will run. This is useful for legacy applications so end users don't need to approve security exceptions to run.  Java Mission Control 5.4 with new ease-of-use enhancements and launcher integration with Eclipse 4.4 JavaFX on ARM Nashorn performance improvement by persisting bytecode after inital compilation There's much more information to be found in the JDK 8u20 Release Notes.

  • Test-Driven Development with plain C: manage multiple modules

    - by Angelo
    I am new to test-driven development, but I'm loving it. There is, however, a main problem that prevents me from using it effectively. I work for embedded medical applications, plain C, with safety issues. Suppose you have module A that has a function A_function() that I want to test. This function call a function B_function, implemented in module B. I want to decouple the module so, as James Grenning teaches, I create a Mock module B that implements a mock version of B_function. However the day comes when I have to implement module B with the real version of B_function. Of course the two B_function can not live in the same executable, so I don't know how to have a unique "launcher" to test both modules. James Grenning way out is to replace, in module A, the call to B_function with a function pointer that can have the value of the mock or the real function according to the need. However I work in a team, and I can not justify this decision that would make no sense if it were not for the test, and no one asked me explicitly to use test-driven approach. Maybe the only way out is to generate different a executable for each module. Any smarter solution? Thank you
