  • How to fix the copy/paste-pattern?

    - by Lenny222
    Where i work, people (consultants) feel pressed to release features as fast as possible. So instead of spending too much time on thinking about how to do things the right way or because they don't want to break anything, code gets copied from different modules and modified. It's not easy to prevent this, since the code base is open to the whole company. Lots of people work on this. Now that the mess is there already, what is the best way to remove those redundancies without breaking too much?

  • Given a RGB color x, how to find the most contrasting color y?

    - by Arthur Wulf White
    I have to mark a certain item in a way that will make it stick-out in the background. I need it to be surrounded with the color that contrasts the background as much as possible so it will pop out and easily noticeable by the player. Lets say I know the background is color 'x', how do I find 'y' such that it will be very contrasting to 'x' and easy to notice in a background where 'x' is a dominant color? I first thought about inverting color 'x' and then I noticed that when 'x' is a medium shade of gray, if I invert 'x' to get 'y', then 'y' is also a medium shade of gray which does not work.

  • New videos available #dax #ssas #powerpivot

    - by Marco Russo (SQLBI)
    The collaboration I and Alberto started with Project Botticelli is starting producing content. At this point we have three videos available: DAX in Action shows the power of DAX in PowerPivot solving common patterns not so easy or fast to solve in other languages DAX: Calculated Columns vs. Measures shows the difference between calculated columns and measures in DAX Introduction to DAX has a content corresponding to the title! The first two videos are freely available, the third one is longer and visible only to subscribers. The goal for this series of video is to reach advanced Excel users and BI developers that are new to DAX. If we should categorize this content, it’s a sort of level 200 session in a conference. I don’t expect readers of this blog to watch this video (if not for the sake of curiosity!) but if you have to explain this subject to anyone else and you have other priorities… well, you can add this post to the list of resources you provide for studying the subject!

    I need to build complex sql queries programatically, based on large filter conditions. For example, below are few sample/hypothitical filter conditions, based on which i need to fetch users Country: india States: Andhra Pradesh(AP), Gujarat(GUJ), karnataka(KTK) Districts: All districts in AP except 3 district, 5 any districts from GUJ, all district from KTK except 1 district Cities: All cities in AP, all cities except few, include only 50 specific cities from KTK Villages: similar conditions like above with varies combinations... Currently, we have a query builder, which is very complex in nature, and not easy to modify/re-factory for improvements. So, thinking of complete re-design of it. Any suggesations on how to build this kind of complex query builders programmatically using some best practices/deisgn patterns?

  • What's a good tool for Scrum Project Management in game development? [closed]

    - by BleakCabalist
    I'm looking for an efficient, easy-to-learn tool for Scrum project management not for proffesional use but to use it in my thesis concerning the use of Scrum in game development. Basically I want to visualize a production process of a hypothetical game. Some fragments of the production process should be really detailed to make my point, so basically user stories, tasks, burndown charts etc. are a must. I'm using Scrum, Kanban and some Lean practices for eliminating waste. I also want to use Extreme Programming practices in this production process including TDD and Continuous Integration. I have zero experience in proffesional project management so I need something that's fairly simple to use for a newb like me. Anyone can recommend a tool like that? For now I was thinking about TargetProcess and ScrumWorks. Thanks.

  • Alternatives to multiple sprite batches for achieving 2D particle system depth

    - by Ergwun
    In my 2D XNA game, I render all my sprites with a single sprite batch using SpriteSortMode.BackToFront and BlendState.AlphaBlend. I'm adding a particle system based on the App Hub particles sample. Since this uses SpriteSortMode.Deferred and BlendState.Additive, I will need to have two SpriteBatch.Begin / SpriteBatch.End pairs: one for 'regular' sprites, and one for particles. In my top-down shooter, If I want to have explosions appear under planes, but above the ground, then I believe I will have to have three Begin/End pairs, first to draw everything under the explosions, then to draw the explosions, then to draw everything above the explosions. If I want to have particle effects at multiple different depths, then I'm going to need even more Begin/Endpairs. This is all easy to code, but I'm wondering if there is an alternative way to handle this?

  • Is static universally "evil" for unit testing and if so why does resharper recommend it?

    - by Vaccano
    I have found that there are only 3 ways to unit test (mock/stub) dependencies that are static in C#.NET: Moles TypeMock JustMock Given that two of these are not free and one has not hit release 1.0, mocking static stuff is not too easy. Does that make static methods and such "evil" (in the unit testing sense)? And if so, why does resharper want me to make anything that can be static, static? (Assuming resharper is not also "evil".) Clarification: I am talking about the scenario when you want to unit test a method and that method calls a static method in a different unit/class. By most definitions of unit testing, if you just let the method under test call the static method in the other unit/class then you are not unit testing, you are integration testing. (Useful, but not a unit test.)

  • How can I recover from a frozen app when connecting over VNC

    - by Pablojim
    I have a htpc running 10.10. It has no keyboard or mouse attached, so I connect over vnc for administration and manual tasks. This usually works fine but every so often an app running in fullscreen mode crashes. All I want to be able to do is kill this app from VNC. Is there a keyboard shortcut to do this that will preserve the VNC connection? If I use CTRL + ALT + F1, I see the terminal but can no longer control it from VNC. Trying to return to the desktop doesn't work either? Any easy process I can follow?

  • How do I port my Ubuntu from my Desktop to Laptop

    - by Bragboy
    Hi, I am currently using Ubuntu 10.04 installed on my desktop box. I have got a new laptop and I will be using it from now on. But I will have to do the setup all over again (setting up applications/updates). Plus many of my preferences and tweaks I've had in my desktop will be lost and those too I will have to all over again. Is there an easy way where I can just take image or something and use it in my laptop?? Any help/pointers/links are much appreciated.

  • [News] Le mouvement NoSQL et MongoDB

    Le mouvement "NoSQL" est une communaut? cr??e dans le but de promouvoir les bases de donn?es non relationnelles (d'o? le terme NoSQL). Dans cet hymne ? ce mouvement, Michael Kennedy, instructeur pour DevelopMentor, d?crit les pr?ceptes de NoSQL en l'illustrant ? travers un moteur finalement peu connu du grand public, MongoDB. A lire, tr?s int?ressant m?me si on ne partage pas l'opinion de cette communaut? : "(...) A basic SQL Server cluster might run you $100,000 just to get it up and running on decent hardware.

  • Sign In With Facebook - Business Issues

    - by Joshiatto
    I've got an issue where this company wants to provide all sorts of whiz bang features to their users that require an insane number of facebook permissions for their FB app. Being that my name is going to be attached to this, I would rather give them a solution which allows for easy sign in and asks for the minimum permissions up front. This would give them a huge boost in registrations and activity publishing across the site with the potential to "go viral". If we ask for a ton of permissions up front I know for a fact we will not go viral and will probably incur much wrath from the blogosphere. What would you do?

  • To My 24 Year Old Self, Wherever You Are&hellip;

    - by D'Arcy Lussier
    A decade is a milestone in one’s life, regardless of when it occurs. 2011 might seem like a weird year to mark a decade, but 2001 was a defining year for me. It marked my emergence into the technology industry, an unexpected loss of innocence, and triggered an ongoing struggle with faith and belief. Once you go through a valley, climbing the mountain and looking back over where you travelled, you can take in the entirety of the journey. Over the last 10 years I kept journals, and in this new year I took some time to review them. For those today that are me a decade ago, I share with you what I’ve gleamed from my experiences. Take it for what it’s worth, and safe travels on your own journeys through life. Life is a Performance-Based Sport Have confidence, believe you’re capable, but realize that life is a performance-based sport. Everything you get in life is based on whether you can show that you deserve it. Performance is also your best defense against personal attacks. Just make sure you know what standards you’re expected to hit and if people want to poke holes at you let them do the work of trying to find them. Sometimes performance won’t matter though. Good things will happen to bad people, and bad things to good people. What’s important is that you do the right things and ensure the good and bad even out in your own life. How you finish is just as important as how you start. Start strong, end strong. Respect is Your Most Prized Reward Respect is more important than status or ego. The formula is simple: Performing Well + Building Trust + Showing Dedication = Respect Focus on perfecting your craft and helping your team and respect will come. Life is a Team Sport Whatever aspect of your life, you can’t do it alone. You need to rely on the people around you and ensure you’re a positive aspect of their lives; even those that may be difficult or unpleasant. Avoid criticism and instead find ways to help colleagues and superiors better whatever environment you’re in (work, home, etc.). Don’t just highlight gaps and issues, but also come to the table with solutions. At the same time though, stand up for yourself and hold others accountable for the commitments they make to the team. A healthy team needs accountability. Give feedback early and often, and make it verbal. Issues should be dealt with immediately, and positives should be celebrated as they happen. Life is a Contact Sport Difficult moments will happen. Don’t run from them or shield yourself from experiencing them. Embrace them. They will further mold you and reveal who you will become. Find Your Tribe and Embrace Your Community We all need a tribe: a group of people that we gravitate to for support, guidance, wisdom, and friendship. Discover your tribe and immerse yourself in them. Don’t look for a non-existent tribe just to fill the need of belonging though that will leave you empty and bitter when they don’t meet your unrealistic expectations. Try to associate with people more experienced and more knowledgeable than you. You’ll always learn, and you’ll always remember you have much to learn. Put yourself out there, get involved with the community. Opportunities will present themselves. When we open ourselves up to be vulnerable, we also give others the chance to do the same. This helps us all to grow and help each other, it’s very important. And listen to your wife. (Easter *is* a romantic holiday btw, regardless of what you may think.) Don’t Believe Your Own Press Clippings (and by that I mean the ones you write) Until you have a track record of performance to refer to, any notions of grandeur are just that: notions. You lose your rookie status through trials and tribulations, not by the number of stamps in your passport. Be realistic about your own “experience and leadership” and be honest when you aren’t ready for something. And always remember: nobody really cares about you as much as you think they do. Don’t Let Assholes Get You Down The world isn’t evil, but there is evil in the world. Know the difference and don’t paint all people with the same brush. Do be wary of those that use personal beliefs to describe their business (i.e. “We’re a [religion] company”). What matters is the culture of the organization, and that will tell you the moral compass and what is truly valued. Don’t make someone or something a priority that only makes you an option. Life is unfair and enemies/opponents will succeed when you fail. Don’t waste your energy getting upset at this; the only one that will lose out is you. As mentioned earlier, nobody really cares about you as much as you think they do. Misc Ecclesiastes is bullshit. Everything is certainly *not* meaningless. Software development is about delivery, not the process. Having a great process means nothing if you don’t produce anything. Watch “The Weatherman” (“It’s not easy, but easy doesn’t enter into grownup life.”). Read Tony Dungee’s autobiography, even if you don’t like football, and even if you aren’t a Christian. Say no, don’t feel like you have to commit right away when someone asks you to.

  • Developing an online email service [closed]

    - by Richard Stokes
    I am interested in developing an online email service (e.g. Gmail, Hotmail, but on a much smaller scale) allowing people to sign up for free email addresses on my domain. The domain in question is already purchased, but I have no idea how to even start. I was hoping to code this using a Ruby framework such as Rails or Sinatra. Firstly, are there any libraries/pre-made solutions to this problem that exist already that would be easy enough to just plug-in to my own site? Secondly, if there are no real pre-made solutions, what are the general steps I need to take to accomplish this task?

  • User eXperience

    - by Daniel Moth
    The last few months I have been spending a lot of time designing (and help design) the developer experience for the areas I contribute to (in future versions of Visual Studio). As a technical person who defines feature sets, it is easy to get engulfed in the pure technical side of things and ignore the details that ultimately make users "love" using the product to achieve their goal, instead of just "having to use" it. Engaging in UX design helps me escape that trap. In case you are also interested in the UX side of development, I thought I'd share an interesting site I came across: UX myths. In particular, I recommend reading myths 9, 10, 12, 13, 14, 15 and 21. Let me know if there are other UX resources you recommend… Comments about this post welcome at the original blog.

  • Building iPhone Interfaces for Oracle E-Business Suite

    - by Shay Shmeltzer
    Over on his blog Juan has been showing you how simple it is to develop a rich Web user interface with ADF accessing Oracle E-Business Suite data and even exposing it on an iPad. In this entry I'm starting from his sample application and I'm showing how easy it is to build an interface that will look great on an iPhone (or other mobile devices) using Oracle ADF Mobile Browser. For those of you who are just using ADF and never tried ADF Mobile Browser - you'll find that the development experience is quite familiar and similar to your normal Web application development. In the latest version of JDeveloper (11.1.2.1) which I'm usingin this demo we have a built-in skin that will give your application the native iOS look and feel. In the demo I achieve this by setting the styleclass of a tr:panelHeader component to af_m_toolbar to get this. For more on this styling read the doc. Check out this quick demo:

  • Uninstalling application built from source

    - by Nik
    I know that Ubuntu has come a long way in helping new users to get used to their linux system..and making things as easy as possible. One most important aspect is installing and uninstalling applications in ubuntu. Thanks to Ubuntu Software Center it is a breeze! However I noticed that when I compiled and installed a game from its source (battleship), it does not appear under the history tab in the Ubuntu Software Center. And also you cannot uninstall it through the software center but have to resort to the command line to do this. I do not mind doing it however I am sure some other users might not be comfortable with this. Is this a bug?

  • Calculating WPM given a variable stream of input

    - by Jaxo
    I'm creating an application that sits in the background and records all key presses (currently this is done and working; an event is fired every keydown/keyup). I want to offer a feature for the user that will show them their WPM over the entire session the program has been running for. This would be easy if I added a "Start" and "End" button to activate a timer, but I need to detect only when the user is typing continuously - ignoring all one-time keyboard shortcuts and breaks the user takes from typing. How in the world do I approach this? Is this even realistically & accurately possible?

  • How to restore GRUB without re-installing the OS?

    - by Calixte
    A friend of mine has a Packard Bell laptop that came with Windows pre-installed. I installed Ubuntu on it and it works fine, but everytime she tried to boot Windows on it (fortunately rarely) it fails and the computer is unable to boot any OS anymore. Upon boot, the computer stops on a black screen with a GRUB Rescue prompt. Is there any way to restore GRUB without re-installing Ubuntu? (preferably an easy way as I cannot do it for her and she is not extremely computer literate) Also (but less important), is there a way to configure GRUB (or something else) so that Windows won't destroy it on every boot attempt?

  • Web technologies on GUI apps

    - by Apalala
    I developed many GUI applications for the Windows platform during my early professional career, and saw several GUI frameworks come, have whole magazines devoted to them, and then fade away. MFC is iconic. Tasked with writing yet another GUI application, I starter researching cross-platform frameworks like Qt and WxWindows. I found the same steep learning curves I knew from before, and tooling doesn't help much in building a functional and elegant user interface because its clumsy and complicated. But people are building beautiful and functional UIs on the Web all the time (look at this site!). The standards, the libraries, and the tools are certainly there. My thought and my question: Why not write a GUI in which most of the UI is handled by an embedded browser? I already know that the Qt widgets support a large part of CSS and JavaScript, and programmers with good knowledge about web development are relatively easy to find, ..., so... Have you done something like that before? What's your experience/advise?

  • problem on static link to libsmbclient.a

    - by Rex
    I've tried to develop a library using libsmbclient-dev to access net share folders. I wish to static link libsmbclient.a in my project , but a lot of error happens when I tried to static link it, it seems that the libsmbclient.a doesn't include some objects it needed , while everything goes well with libsmbclient.so. Because my project need to support various linux versions like centOS , Ubuntu ..., we wish not to install libsmbclient-dev everywhere. Can anybody tell me that if I can static link this libsmbclient.a in an easy way ? Or what kind of installation strategy should I take to cause less trouble to users? If anyone have use this library to develop projects before , can you tell me how you deal with this case? Thank you very much!!!
