  • Which office suite is the ideal alternative to MSOffice?

    - by user64720
    Let's say I want to drop MSOffice permanently and switch to a free alternative, not having the need of opening the documents on other PC's except my own (I can also carry a portable version on a pendrive and edit the docs anywhere). I know 3 free office suites - LibreOffice, Abiword and Calligra. Which one of these is the most complete and provides the best features to be a viable alternative to MSOffice, without compromising the quality of the work I can produce on Office apps? Notice that I'm not focusing the question on compatibility between MSOffice and other suites but instead I am comparing their quality, taking in comparison MSOffice.

  • Why does Unity in 2d mode employ scaling and the default othographic size the way it does?

    - by Neophyte
    I previously used SFML, XNA, Monogame, etc to create 2d games, where if I display a 100px sprite on the screen, it will take up 100px. If I use 128px tiles to create a background, the first tile will be at (0,0) while the second will be at (129,0). Unity on the other hand, has its own odd unit system, scaling on all transforms, pixel-to-units, othographic size, etc etc. So my question is two-fold, namely: Why does Unity have this system by default for 2d? Is it for mobile dev? Is there a big benefit I'm not seeing? How can I setup my environment, so that if I have a 128x128 sprite in Photoshop, it displays as a 128x128 sprite in Unity when I run my game? Note that I am targeting desktop exclusively.

  • Computer Freezes After GRUB

    - by paulmcg421
    Ok so I've just built my first computer and have got it running, here are the specs: Asus P8Z68-V PCI-E LX Motherboard, Intel Core i5-2500K, Patriot Memory 8GB (2 x 4GB), Viper Xtreme Series PC3-15000 1866MHz CL9 Division 2 Edition Memory (PXD38G1866ELK), Gigabyte ATI Radeon 6850 820MHz 1GB PCI-E HDMI OC Windforce 2x 500w Ezcool 24pin psu as standard. The only thing I haven't bought new is the hard drive, it's a 250gb that I removed from an Acer Aspire M5100 that I was using till now with no OS Problems. On start up it runs fine but is unresponsive after the GRUB menu disappears to load Ubuntu (Oneric Ocelot). The keyboard lights then turn off and the screen eventually returns that there is no signal. Is there anything that I could be missing from building? (This is my first attempt at building my own PC) Any input would be appreciated, thanks !

  • DirectX 9.0c and C++ GUI

    - by SullY
    Well, I'm trying to code a gui for my engine, but I've got some problems. I know how to make a UI overlay but buttons are still black magic for me. Anything I tried was to compilcated ( if it goes big ). To Example I tried to look if the mouse position is the same as the Pixel that is showing the button. But If I use some bigger areas it's getting to complicated. Now I'm searching for a Tutorial how to implement your own gui. I'm really confused about it. Well I hope you have/ know some good tutorials. By the way, I took a look at the DXUTSample, but it's to big to get overview.

  • Breaking in to Programming

    - by Kevin
    I've noticed that there is a gap between getting formal education in computer science as a student and entry-level/junior programming jobs. Obviously entry-level programming requires that you know some programming but how much do you need to break in? I'm in a QA non-coding role with basically a minor in CS, looking to improve my own programming skills to eventually switch industries. However I'm completely at a loss as to what I should be focusing on learning and am curious as to the steps other people have taken to get experience post-undergrad.

  • ecommerce options for 5-6 products [closed]

    - by user5252
    Possible Duplicate: Which Ecommerce Script Should I Use? We're looking to develop a simple e-commerce solution to sell 5-6 products. We'd rather not have to use PayPal's buttons (buy it now!) if there's an existing alternative, but would also for budget/time constraints don't want to roll our own. Are there any small, basic ecommerce solutions available that would allow this? I did look at Foxy Cart but the monthly fee was a bit of a turn off. (I must sound extremely fussy I'm aware!) Something like Zen would just be overkill for our needs. Thanks for any suggestions.

  • How to set Ubuntu as wireless accespoint in the GUI way?

    - by Agmenor
    My aim is to make my Ubuntu machine be a wireless accesspoint using wifi. Of course I found two AskUbuntu questions already treating that; this one and that one. Nevertheless, as far as I am concerned I would like to set up such a network in the Graphical User Interface (GUI) way. Please avoid solutions with the command line. So a solution suggesting to use Network Manager would be really welcomed. Please name and describe very precisely each step, so I can easily find the equivalent in my own language. Thank you for your answers!

  • Channel 9 Interview: Array and Collection Initializers in Visual Basic 2010 (Beth Massi, Spotty Bowl

    Ive written about collection initializers on my blog before, but I thought Id catch up with the VB Team to tell me more about how they really work. In this interview Spotty Bowles, a tester on the VB Compiler team, shows us a couple of new language features: Array and Collection Initializers. He gives us insight into how they are implemented in the compiler and best practices on how to use them in our code. Additionally, he discusses how to extend Collection Initializers with your own extension...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Kubuntu 12.04: Change login screen background?

    - by drezabek
    I am having trouble changing my login screen background. I can select the default wall paper, the Kde-default one, but when ever I select my own custom wallpaper, there is no image, just a solid color. Normally, I would just ignore it, but the thing that bugs me is that this is a fresh install of Kubuntu 12.04 64bit, and the OS before this one, the one I overwrote, I had no trouble using the exact same image as the background... Settings In the System Settings application, Login Screen settings, Background tab, enable background, Under "Background", selected Picture, under options, selected Position: Scaled. Colors: Single Color. Blending: No Blending.

  • Does anyone have a good example/sample of "goto" spaghetti code? [closed]

    - by ArtB
    I've read a lot about how GoTo was considered harmful and removed for other control structures that were more intuitive. Does anyone have a good example / sample of goto spaghetti code? Preferrably, the sample code should be difficult to follow, but realtively easy when rewritten into more conventional control structures. I know I could try to write you some of my own, but I've never really used goto and don't think I could due justice to the headaches its abuse can lead to. I want this for didactic purposes to train junior developers on what to avoid. Mainly, to point to illustrate how OOP is taking the same idea to next logical consequence. EDIT: by good example I mean code that is terrible to read and abuses it, rather than code that uses goto for reasonable optimization

  • Map, Set use cases in a general web app

    - by user2541902
    I am currently working on my own Java web app (to be shown in interview to get a Java job). So I've not worked on Java in professional environment, so no guidance. I have database, entity classes, JPA relationships. Use cases are like, user has albums, album has pics, user has locations, location has co-ordinates etc. I used List (ArrayList) everywhere. I can do anything with List and DB, get some entry, find etc. For example, I will keep the list of users in List, then use queries to get some entry (why would I keep them in Map with id/email as key?). I know very well the working and features, implementing classes of Map, Set. I can use them for solving some algorithm, processing some data etc. In interviews, I get asked have you worked with these, where have you used them etc. So, Please tell me cases where they should be used (DB or any popular real use case).

  • Styling ASP.NET MVC Error Messages

    - by MightyZot
    Originally posted on: http://geekswithblogs.net/MightyZot/archive/2013/11/11/styling-asp.net-mvc-error-messages.aspxOff the cuff, it may look like you’re stuck with the presentation of your error messages (model errors) in ASP.NET MVC. That’s not the case, though. You actually have quite a number of options with regard to styling those boogers. Like many of the helpers in MVC, the Html.ValidationMessageFor helper has multiple prototypes. One of those prototypes lets you pass a dictionary, or anonymous object, representing attribute values for the resulting markup. @Html.ValidationMessageFor( m => Model.Whatever, null, new { @class = “my-error” }) By passing the htmlAttributes parameter, which is the last parameter in the call to the prototype of Html.ValidationMessageFor shown above, I can style the resulting markup by associating styles to the my-error css class.  When you run your MVC project and view the source, you’ll notice that MVC adds the class field-validation-valid or field-validation-error to a span created by the helper. You could actually just style those classes instead of adding your own…it’s really up to you. Now, what if you wanted to move that error message around? Maybe you want to put that error message in a box or a callout. How do you do that? When I first started using MVC, it didn’t occur to me that the Html.ValidationMessageFor helper just spits out a little bit of markup. I wanted to put the error messages in boxes with white backgrounds, our site originally had a black background, and show a little nib on the side to make them look like callouts or conversation bubbles. Not realizing how much freedom there is in the styling and markup, and after reading someone else’s post, I created my own version of the ValidationMessageFor helper that took out the span and replaced it with divs. I styled the divs to produce the effect of a popup box and had a lot of trouble with sizing and such. That’s a really silly and unnecessary way to solve this problem. If you want to move your error messages around, all you have to do is move the helper. MVC doesn’t appear to care where you put it, which makes total sense when you think about it. Html.ValidationMessageFor is just spitting out a little markup using a little bit of reflection on the name you’re passing it. All you’ve got to do to style it the way you want it is to put it in whatever markup you desire. Take a look at this, for example… <div class=”my-anchor”>@Html.ValidationMessageFor( m => Model.Whatever )</div> @Html.TextBoxFor(m => Model.Whatever) Now, given that bit of HTML, consider the following CSS… <style> .my-anchor { position:relative; } .field-validation-error {    background-color:white;    border-radius:4px;    border: solid 1px #333;    display: block;    position: absolute;    top:0; right:0; left:0;    text-align:right; } </style> The my-anchor class establishes an anchor for the absolutely positioned error message. Now you can move the error message wherever you want it relative to the anchor. Using css3, there are some other tricks. For example, you can use the :not(:empty) selector to select the span and apply styles based upon whether or not the span has text in it. Keep it simple, though. Moving your elements around using absolute positioning may cause you issues on devices with screens smaller than your standard laptop or PC. While looking for something else recently, I saw someone asking how to style the output for Html.ValidationSummary.  Html.ValidationSummery is the helper that will spit out a list of property errors, general model errors, or both. Html.ValidationSummary spits out fairly simple markup as well, so you can use the techniques described above with it also. The resulting markup is a <ul><li></li></ul> unordered list of error messages that carries the class validation-summary-errors In the forum question, the user was asking how to hide the error summary when there are no errors. Their errors were in a red box and they didn’t want to show an empty red box when there aren’t any errors. Obviously, you can use the css3 selectors to apply different styles to the list when it’s empty and when it’s not empty; however, that’s not support in all browsers. Well, it just so happens that the unordered list carries the style validation-summary-valid when the list is empty. While the div rendered by the Html.ValidationSummary helper renders a visible div, containing one invisible listitem, you can always just style the whole div with “display:none” when the validation-summary-valid class is applied and make it visible when the validation-summary-errors class is applied. Or, if you don’t like that solution, which I like quite well, you can also check the model state for errors with something like this… int errors = ViewData.ModelState.Sum(ms => ms.Value.Errors.Count); That’ll give you a count of the errors that have been added to ModelState. You can check that and conditionally include markup in your page if you want to. The choice is yours. Obviously, doing most everything you can with styles increases the flexibility of the presentation of your solution, so I recommend going that route when you can. That picture of the fat guy jumping has nothing to do with the article. That’s just a picture of me on the roof and I thought it was funny. Doesn’t every post need a picture?

  • How to design console application with good seperation of UI from Logic

    - by JavaSa
    Is it considered an overkill for console application to be design like MVC , MVP or N tier architecture? If not which is more common and if you can link me to simple example of it. I want to implement a tic tac toe game in console application. I have a solution which hold two projects: TicTacToeBusinessLogic (Class library project) and TicTacToeConsoleApplication (Console application project) to represent the view logic. In the TicTacToeConsoleApplication I've Program.cs class which holds the main entry point (public static void Main). Now I face a problem. I want the game to handle its own game flow so I can: Create new GameManager class (from BL) but this causing the view to directly know the BL part. So I'm a little confused how to write it in an acceptable way. Should I use delegates? Please show me a simple example.

  • Introducing Task-It. A real-world application using RadControls for Silverlight 4

    This is the first in a series of blog posts based around an application called Task-It that I have developed in Silverlight 4. Task-It is real-world application designed for people that need a simple way to manage the numerous tasks that we all strive to accomplish on a daily basis. Figure 1: Task-It Tasks page Figure 2: Task-It Dashboard page I have developed this application for several reasons: There are many task management applications out there, and I have used quite a few of them, but I havent found one that really grabbed me. Many of these applications had their strong points,but some were overly complex, some lacked key features, some cost too much money, and so forth. I thought it would be nice to identify the best parts of each, and take my stab at building my own. During my evaluation of task management applications, I have not yet ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • How To Remote Control Your Home Computer From Anywhere With VNC

    - by Chris Hoffman
    VNC allows you to remotely access a computer and use its desktop, either over the Internet or from another room in your house. Windows includes a Remote Desktop feature, but it’s only available in Professional editions of Windows. Some people may prefer TeamViewer or another service instead, but VNC allows you to install and manage your own server without using a centralized service. VNC clients and servers are available for all platforms, but we’ll be covering Windows here.

  • C++ AMP recording and slides

    - by Daniel Moth
    Yesterday we announced C++ Accelerated Massive Parallelism. Many of you want to know more about the API instead of just meta information. I will trickle more code over the coming months leading up to the date when we will share actual bits. Until you have bits in your hand, it is only your curiosity that is blocked, so I ask you to be patient with that and allow me to release this on our own schedule ;-) You can now watch my 45-minute session introducing C++ AMP on channel9. You will also want to download the slides (pdf), because they are not readable in the recording. Comments about this post welcome at the original blog.

  • Programming language specific package management systems

    - by m0nhawk
    There are some programming languages for which exist their own package management systems: CTAN for TeX CPAN for Perl Pip & Eggs for Python Maven for Java cabal for Haskell Gems for Ruby Is there any other languages with such systems? What about C and C++? (that's the main question!) Why there are no such systems for them? And isn't creating packages for yum, apt-get or other general package management systems better? UPD: And what about unification? Have someone tried to unify that "the zoo"? If yes, looks like that project didn't succeed.

  • Advice Required Regarding Creating a Self Learning, Self Organizing Programming Team....

    - by tGilani
    Hello I'm a senior student at my university and chairperson of IEEE Student Branch there. Recently I was thinking of some idea to acquaint students with the professional environment, how software is produced in the industry and get a practical experience.. Obviously trips to software houses are not enough and we cannot provide this many internships. So the idea of simulating a software house within the university popped in. Resources at my disposal are students with their own laptops, university UPS and lan network with internet access, and a reasonably sized room with a whiteboard and three hours free time daily.. :) However, I have absolutely no idea where to begin with. Milestones or whatever it may be called, are Requirements Document generation, sharing of resources, delegation of tasks, version controlling etc... I'd really appreciate some advice, programming tools (for JAVA), communication tools etc and other things used in a decent software house... Technologies to be targeted shall be random possibly starting with J2EE Spring Hibernate and Later Visual Programming in .NET C# and ASP.NET MVC as well as Android or iPhone development....

  • Grub2 with BURG: duplicate Windows entries, how do I remove one?

    - by Tomas Lycken
    I have a dual boot system with Ubuntu 12.04 and Windows 7, using GRUB2 (with Burg) as boot loader. For some reason, the Windows installation shows up twice in the boot menu: Ubuntu GNU/Linux, with Linux 3.2.0-24-generic Ubuntu GNU/Linux, with Linux 3.2.0-24-generic (recovery mode) Windows 7 (loader) (on /dev/sda1) Windows 7 (loader) (on /dev/sda2) If I look in my partition table, /dev/sda2 is C:\ of the Windows installation, and /dev/sda1 is the "System Reserved" partition (which, IIRC, is Windows' own bootloader). Furthermore, gparted shows /dev/sda2 - but no other partitions - with a boot flag: What is going on here? I'd like to have only the entries for Ubuntu and one entry for Windows in my boot menu - how do I remove one of them?

  • Interview question ranking FizzBuzz (1), implementing malloc (10)

    - by blrs
    I'd like to have your opinion on the difficulty of the following interview question: Find the subarray with maximum sum in an array of integers in O(n) time. This trivial sounding problem was made famous by Jon Bentley in his Programming Pearls where he uses it to demonstrate algorithm design techniques. On a scale of 1-10, 1 being the FizzBuzz (or HoppityHop) test and 10 being implement the C stdlib function malloc(), how would you rank the above problem? I think the people who can best answer this question are those who have read Programming Pearls and have tried to solve this problem on their own. To motivate those who haven't, 'Programming Pearls' gets featured many times in the 'Top 10 programming books' list.

  • Best practices for Persona development

    - by user12277104
    Over the years, I have created a lot of Personas, I've co-authored a new method for creating them, and I've given talks about best practices for creating your own, so when I saw a call for participation in the OpenPersonas project, I was intrigued. While Jeremy and Steve were calling for persona content, that wasn't something I could contribute -- most of the personas I've created have been proprietary and specific to particular domains of my employers. However, I felt like there were a few things I could contribute: a process, a list of interview questions, and what information good personas should contain. The first item, my process for creating data-driven personas, I've posted as a list of best practices. My next post will be the list of 15 interview questions I use to guide the conversations with people whose data will become the personas. The last thing I'll share is a list of items that need to be part of any good persona artifact -- and if I have time, I'll mock them up in a template or two.

  • Career Shifters: How to compete with IT/ComSci graduates

    - by CareerShifter
    I am wondering what are the chances of a career shifter (mid 20's), who have maybe 3-6 months programming experience vs. younger fresh IT/Com Sci graduates. You see, even though I really love programming (Java/J2EE), but nobody gives me a feedback when I apply online. maybe because they preferred IT/ComSci graduates vs a career shifter like me.. So can you advice on how to improve my chance on being hired. How can i get a real-job programming experince if nobody is hiring me. I can make my own projects (working e-commerce site blah blah) but it is still different from the real job. And my codes are working but it still needs a lot of improvement and no one can tell me how to improve it because no one sees it (because I'm doing it alone?). Do you know any open source websites (java/j2ee/jee) / online home-based jobs who accepts java/j2ee/jee trainees.. Thank you very much

  • Ubuntu on Thinkpad Edge 11

    - by lasseespeholt
    Hi, I think a community wiki on problems (and solutions) when installing Ubuntu (10.10) on a Thinkpad Edge 11 would be nice (because I just got one ;)). I'll contribute with my own problems and solutions, and hope others will join too. Thinkwiki entry for the Edge 11 Known problems: No wifi-driver, solution: answer #1, answer #2 Fan is load, even though it's on auto. No solution. Thinkfan is a possible solution, but correction values for sensors should be supplied (mapping sensors to specific areas). Also, one sensor is between -100C and +100C - maybe some kind of deactivation would help.

  • Cloud computing cost savings for large enterprise

    - by user13817
    I'm trying to understand whether cloud computing is meant for small to medium sized companies OR also for large companies. Imagine a website with a very large user base. The storage and bandwidth demands as well as the number of database transactions are incredibly high. The website might be hosting videos, music, images, etc. that keep the demands high. Does it make sense to be in the cloud when you know you need huge volumes of storage, bandwidth, and GET,PUT,etc. requests? (Each of these variables costs money in the cloud) OR does it make sense to build your own infrastructure? I can see the cost savings of cloud computing if you are a small business, but if you were aiming at the next big thing on the Internet, I can't quite see the benefits.
