  • Are there any downsides of 2 developers getting married ?

    - by simpson
    I remember that in my first year at college, the professor told us that his wife is also a software developer, and a few decades ago when there has been a tough period of 2-3 years in the software field they both had been unemployed and had experienced some hard times. Of course I am not asking about this economic downside, as it is a general conclusion for a family working in the same field, and is not related specifically to programming. I am asking about any other possible downsides of a family where both people are programmers. To all developers married to developers - I am not asking if it is "horrible" or something like that, of course it's not, just if there are any specific issues (all kinds of relationships has some specific issues, and at the same time are immune to others). And yes, I am asking about a male developer married to a female developer, I am clarifying to avoid jokes like "I believe that 2 developers can get married in some states" and so on :)

  • How to Apply a Business Card Template to a Contact and Customize it in Outlook 2013

    - by Lori Kaufman
    If you want to add a business card template to an existing contact in Outlook, you can do so without having to enter all of the information again. We will also show you how to customize the layout and format of the text on the card. Microsoft provides a couple of business card templates you can use. We will use their Blue Sky template as an example. To open the archive file for the template you downloaded, double-click on the .cab file. NOTE: You can also use a tool like 7-Zip to open the archive. A new Extract tab becomes available under Compressed Folder Tools and the files in the archive are listed. Select the .vcf file in the list of files. This automatically activates the Extract tab. Click Extract To and select a location or select Choose location if the desired location is not on the drop-down menu. Select a folder in which you want to save the .vcf file on the Copy Items dialog box and click Copy. NOTE: Use the Make New Folder button to create a new folder for the location, if desired. Double-click on the .vcf file that you copied out of the .cab archive file. By default, .vcf files are associated with Outlook so, when you double-click on a .vcf file, it automatically opens in a Contact window in Outlook. Change the Full Name to match the existing contact to which you want to apply this template. Delete the other contact info from the template. If you want to add any additional information not in the existing contact, enter it. Click Save & Close to save the contact with the new template. The Duplicate Contact Detected dialog box displays. To update the existing contact, select the Update information of selected Contact option. Click Update. NOTE: If you want to create a new contact from this template, select the Add new contact option. With the Contacts folder open (the People link on the Navigation Bar), click Business Card in the Current View section of the Home tab. You may notice that not all the fields from your contact display on the business card you just updated. Double-click on the contact to update the contact and the business card. On the Contact window, right-click on the image of the business card and select Edit Business Card from the popup menu. The Edit Business Card dialog box displays. You can change the design of the card, including changing he background color or image. The Fields box allows you to specify which fields display on the business card and in what order. Notice, in our example, that Company is listed below the Full Name, but no text displays on the business card below the name. That’s because we did not enter any information for Company in the Contact. We have information in Job Title. So, we select Company and click Remove to remove that field. Now, we want to add Job Title. First, select the field below which you want to add the new field. We select Full Name to add the Job Title below that. Then, we click Add and select Organization | Job Title from the popup menu to insert the Job Title. To make the Job Title white like the name, we select Job Title in the list of Fields and click the Font Color button in the Edit section. On the Color dialog box, select the color you want to use for the text in the selected field. Click OK. You can also make text bold, italic, or underlined. We chose to make the Job Title bold and the Full Name bold and italic. We also need to remove the Business Phone because this contact only has a mobile phone number. So, we add a Mobile Phone from the Phone submenu. Then, we need to remove enough blank lines so the Mobile Phone is visible on the card. We also added a website and email address and removed more blank lines so they are visible. You can also move text to the right side of the card or make it centered on the card. We also changed the color of the bottom three lines to blue. Click OK to accept your changes and close the dialog box. Your new business card design displays on the Contact window. Click Save & Close to save the changes you made to the business card for this contact and close the Contact window. The final design of the business card displays in the Business Card view on the People screen. If you have a signature that contains the business card for the contact you just updated, you will also need to update the signature by removing the business card and adding it again using the Business Card button in the Signature editor. You can also add the updated Business Card to a signature without the image or without the vCard (.vcf) file.

  • null values vs "empty" singleton for optional fields

    - by Uko
    First of all I'm developing a parser for an XML-based format for 3D graphics called XGL. But this question can be applied to any situation when you have fields in your class that are optional i.e. the value of this field can be missing. As I was taking a Scala course on coursera there was an interesting pattern when you create an abstract class with all the methods you need and then create a normal fully functional subclass and an "empty" singleton subclass that always returns false for isEmpty method and throws exceptions for the other ones. So my question is: is it better to just assign null if the optional field's value is missing or make a hierarchy described above and assign it an empty singleton implementation?

  • C# Tip - Rendering HTML in a Gridview cell

    - by BobPalmer
    Just a quick tip for working with the gridview in ASP.Net.  If your data column contains HTML text, you've probably seen something like this in your gridview after pulling the data: <font color="red">First Item</font><br/><font color="green">Second Item</font><br/><font color="blue">Third Item</font> To have the relevant column render in HTML, just go to your gridview property pages, find the column you need rendered in HTML, and click 'convert this Field into a TemplateField'.  The result is that as a template field, HTML within your bound data value will be rendered properly.  So our example above would transform into: First Item Second Item Third Item I primarily use this technique for enabling HTML content in comment fields, and to insert line breaks when building the data for these fields. Hope this helps out! -Bob

  • Exposing warnings\errors from data objects (that are also list returned)

    - by Oren Schwartz
    I'm exposing Data objects via service oriented assembly (which on future usages might become a WCF service). The data object is tree designed, as well as formed from allot of properties.Moreover, some services return one objects, others retrieve a list of them (thus disables throwing exceptions). I now want to expose data flow warnings and wondering what's the best way to do it having to things to consider: (1) seperation (2) ease of access. On the one hand, i want the UI team to be able to access a fields warnings (or errors) without having them mapping the field names to an external source but on the other hand, i don't want the warnings "hanged" on the object itself (as i don't see it a correct design). I tought of creating a new type of wrapper for each field, that'll expose events and they'll have to register the one's they care about (but totally not sure) I'll be happy to hear your thoughts. Could you please direct me to a respectful design pattern ? what dp will do best here ? Thank you very much!

  • Check if an object is facing another based on angles

    - by Isaiah
    I already have something that calculates the bearing angle to get one object to face another. You give it the positions and it returns the angle to get one to face the other. Now I need to figure out how tell if on object is facing toward another object within a specified field and I can't find any information about how to do this. The objects are obj1 and obj2. Their angles are at obj1.angle and obj2.angle. Their vectors are at obj1.pos and obj2.pos. It's in the format [x,y]. The angle to have one face directly at another is found with direction(obj1.pos,obj2.pos). I want to set the function up like this: isfacing(obj1,obj2,area){...} and return true/false depending if it's in the specified field area to the angle to directly see it. I've got a base like this: var isfacing = function (obj1,obj2,area){ var toface = direction(obj1.pos,obj2.pos); if(toface+area >= obj1.angle && ob1.angle >= toface-area){ return true; } return false; } But my problem is that the angles are in 360 degrees, never above 360 and never below 0. How can I account for that in this? If the first object's angle is say at 0 and say I subtract a field area of 20 or so. It'll check if it's less than -20! If I fix the -20 it becomes 340 but x < 340 isn't what I want, I'd have to x 340 in that case. Is there someone out there with more sleep than I that can help a new dev pulling an all-nighter just to get enemies to know if they're attacking in the right direction? I hope I'm making this harder than it seems. I'd just make them always face the main char if the producer didn't want attacks from behind to work while blocking. In which case I'll need the function above anyways. I've tried to give as much info as I can think would help. Also this is in 2d.

  • Do database tables need to have IDs?

    - by Arturas M
    Is an ID field is always needed in database tables? In my case I have a user with firstName, lastName and email fields. email is unique and not null, so it could be used as an ID, right? So in that case, could/should I try to remove the ID? Also I want to have another table which extends this one. Let's say its called patient and it has it's own field additionalData and I would like to link the relationship through the email of user I mentioned. So the relationship should be 1 to 1, right? and I wouldn't need the IDs? Somehow MySQL Workbench wants me to use the IDs. What do you guys think. Any suggestions on this topic?

  • RTOS experience

    - by Subbu
    Hi, I have been working as an embedded software engineer on mostly 8 bit micro-controller firmware and desktop/mobile applications development for the past five years. My work on a WinCE project (in which I got introduced to .NET CF) was short lived. I did use core APIs for interrupt processing, peripheral communication, etc...but again, not exactly a pure RTOS environment. In order to get together more solid experience for growing more in the embedded field, I want to work more with RTOSes. Will buying an evaluation board with an RTOS and putting together a project at home be regarded as a good experience or will an online course be more useful? I am just not clear as to what will be regarded as good experience. Any suggestions or directions will greatly help me. I have a passion for the field but just a need a point in the right direction. Thanks for any help in advance. Regards, Subbu

  • Real-Time Multi-User Gaming Platform

    - by Victor Engel
    I asked this question at Stack Overflow but was told it's more appropriate here, so I'm posting it again here. I'm considering developing a real-time multi-user game, and I want to gather some information about possibilities before I do some real development. I've thought about how best to ask the question, and for simplicity, the best way that occurred to me was to make an analogy to the field (or playground) game darebase. In the field game of darebase, there are two or more bases. To start, there is one team on each base. The game is a fancy game of tag. When two people meet out in the field, the person who left his base most recently timewise captures the other person. They then return to that person's base. Play continues until everyone is part of the same team. So, analogizing this to an online computer game, let's suppose there are an indefinite number of bases. When a person starts up the game, he has a team that is located at, for example, his current GPS coordinates. It could be a virtual world, but for sake of argument, let's suppose the virtual world corresponds to the player's actual GPS coordinates. The game software then consults the database to see where the closest other base is that is online, and the two teams play their game of virtual tag. Note that the user of the other base could have a different base than the one run by the current user as the closest base to him, in which case, he would be in two simultaneous battles, one with each base. When they go offline, the state of their players is saved on a server somewhere. Game logic calls for the players to have some automaton-logic of some sort, so they can fend for themselves in a limited way using basic rules, until their user goes online again. The user doesn't control the players' movements directly, but issues general directives that influence the players' movement logic. I think this analogy is good enough to frame my question. What sort of platforms are available to develop this sort of game? I've been looking at smartfoxserver, but I'm not convinced yet that it is the best option or even that it will work at all. One possibility, of course, would be to roll out my own web server, but I'd rather not do that if there is an existing service out there already that I could tap into. I will be developing for iOS devices at first. So any suggestions would be greatly appreciated. I think I need to establish the architecture first before proceeding with this project. Note that darbase is not the game I intend to implement, but, upon reflection, that might not be a bad idea either.

  • CS, SE, HCI, Information Science, Please recommendation for further education of the former performing art manager seeking career in IT industries? [on hold]

    - by Baek Seungjoo
    IT specialists there J Thank you very much for your collective efforts here, and I got huge help reading your professional comments and advices on each questions I have searched so far! This time, I would like to ask for your practical advices or recommendation on what I am struggling on at this moment. I am currently seeking higher education for my career transition from performing art manager and director to “IT software and/or service development and management specialist”. However, as this field is quite new to me, and there are lots of different work positions, I have no idea which grad major I better pursue in order to get qualification. Of course I know this question could sounds wired as it is kind of personal choice. But my lack of understanding on how IT software companies work in general, your practical and experience-based advice will be great help to me, who spent more than two months of self-research on net. OK. Before my question, here is my plan and history, which are quite different from those currently in IT industry I think… 1) Target Firstly, get career transition into IT service or products companies and get experiences. Eventually, pursue IT entrepreneurship in combination with my arts and cultural production and business expertise. 2) Background Career: performing arts director and manager in theatre-based scale opera and musical Art education in youth BA in literature and Chinese studies (Art & Humanities) MA in Cultural & Creative Industries (Art & Humanities) – dissertation with focus on digital prosumption and the lived experience of the prosumer. (a qualitative research on the agents in the digital world) 2) Personally Huge interest in IT hardware and software, and their trend. Skills to build up, repair, tune PCs -of course this is no more than personal hobby, but shows my interests in this field. 4) Problem Encounter a question “So, what do you think you can contribute practically in this position”. This question turn me down everytime I go through job interviews, and I decided more education in the relevant area. Here are my questions. 1) In terms of work positions in IT software companies, I wonder if I can put the comparison of what “Artists” is to “Arts Manager or Director” is what “Developer” is to “Product Manager”. (Of course, this stereotypical division of Artist-Art Manager is out of sense because the domain overlaps to some extent, and is blurring at least in my field, and they are in different contexts, but just speaking easily.) Normally, artist comes with special arts educations, and they live in their own world of artistic inspiration and creation, and they feel alive in practice and on stages. Meanwhile, from the point of staging and managing productions, the role of art manager is critical as well. Our role cares how the production appeals to the audience in effective way, how to make profit and future sustainable management through that, how to set up future strategy in consideration of the external conditions such as political and social circumstances, audience trend and level, other production trends from on-going and historical perspectives, how and what the production make voice to the society from political, economic, humanitarian stances. So, we need keen eyes on economic, political, and societal environment, have to understand human-being and their desires, must know how to make presentation and attract investors, must have sense in managing and fighting over the limited financial resource, how to extend networking and so on. It is common that the two agents create productions in collaboration (normally not in that ideal way but in conflict and fight though J ). So, we need to know each other’s expertise to some extent, for better production. What are the work positions in IT software industries equivalent to the role of “art manager” in performing arts? From my view, considering developers come with special education in the world of computer science, software engineering, or others (self-education sometimes), and they express themselves with the arts of coding, computer languages on the black screen, and make sort of their artistic production online to the audience, I guess there might be someone who collaborate with developers in creating, managing, and launching IT services or products. 2) Which education among CS, SE, HCI, Information Science, is needed for those seeking such work position? Especially for person like me. (At this moment, Information Science has the highest possibility to get in, since I lack Calculus and Math in undergrad educaiton. But please let me know irrespective of this concern, I think there are ways to back it up if CS or SE education needed in my case) 3) Which field between Information Science and HCI can be more practical background regarding job hungting? And which of them have more demands in job market? AS I checked, HCI is more close to CS than IS in its focus of study area. Thank you very much for your patience reading such a long inquiry, and I appreciate to your efforts in advance. Have a nice day in this beautiful summer.

  • Is wikipedia a valuable resource for studying data structures? (can we call it complete?)

    - by Amir Nasr
    Can I depend on wikipedia to learn data structures fully using the list of data structures http://en.wikipedia.org/wiki/List_of_data_structures and the links they refer to? The same question for algorithms http://en.wikipedia.org/wiki/List_of_algorithm_general_topics ?... What's after learning algorithms and data structures? Specializing in a certain field of algorithms such as computer graohics, memory management...etc? or what could be the plan for mastering programming after knowing the language syntax and the background about program design and programming logic? I asked about wikipedia because i would like to find a complete resource or are least a resource which would be enough for the field of data structures instead of searching for separate articles in different places in other words an alternative to books which may even be more complete.

  • Getting a texture from a renderbuffer in OpenGL?

    - by Rushyo
    I've got a renderbuffer (DepthStencil) in an FBO and I need to get a texture from it. I can't have both a DepthComponent texture and a DepthStencil renderbuffer in the FBO, it seems, so I need some way to convert the renderbuffer to a DepthComponent texture after I'm done with it for use later down the pipeline. I've tried plenty of techniques to grab the depth component from the renderbuffer for weeks but I always come out with junk. All I want at the end is the same texture I'd get from an FBO if I wasn't using a renderbuffer. Can anyone post some comprehensive instructions or code that covers this seemingly simple operation? EDIT: Linky to an extract version of the code http://dl.dropbox.com/u/9279501/fbo.cs Screeny of the Depth of Field effect + FBO - without depth(!) http://i.stack.imgur.com/Hj9Oe.jpg Screeny without Depth of Field effect + FBO - depth working fine http://i.stack.imgur.com/boOm1.jpg

  • How do I show an animated gif in the app I am developing?

    - by Agmenor
    I am developing Discvur, a simple Imgur viewer, for the Ubuntu App Showdown. Therefore I use quickly + Glade + Gtk + Python. PyGObject instead of PyGtk would be highly appreciated. I would like to display some animated gifs in my program. What I tried was inserting a viewport, then an image, and then in the 'Edit Image' field I selected a gif animation (in my case "../media/akO1i.gif"). When I run my app, the gif is displayed but it is not moving (I only see the first frame). Is it possible to show animated gifs in my app? What is the best and/or easiest way to do it: use the image widget, or a WebKit field, or something else?

  • In Joomla how to change the module mod_news_show_gk3?

    - by Emerson
    How can I change the mod_news_show_gk3 module to: Change the size of the post image. It uses the first image of the post, but it seems to not be resizing the image. Add an extra field: It is important to show in the main page what is the source of the post. I would then like to add an extra field during post editing time, namely "source", and then I would like to show the source below the title and before the text. Change the title size. Title is oversized and I couldn't find any way to decrease its size. Add a border around the section. Here is the address: http://central.antinovaordemmundial.com/ Thanks!

  • What is the annoying/lacking feature in C#, in your opinion?

    - by Vimvq1987
    To be honest, I'm working with C# everyday, and I can say that I love its elegant syntax. But no language is perfect, so does C#. In my opinion, these two features are missing: Full-featured enum. I was pretty happy with enum in C#, until I know about enum in Java. Of course, we can "simulate" a full-featured enum in C# by class, but it's much better if Microsoft simplify this. Immutable keyword. We are told to let a class/struct immutable whenever possible. But to do that, we have to add readonly keyword to every field, and then if we add setter by a mistake, our class will be mutable, and nobody knows. By immutable keyword, every field will be automatically readonly, and any setter will be prohibited (error when compile). It's like static keyword added to class in C# 2.0 well. what's is your annoying/lacking feature in C#?

  • How is Basic Physics applied in CS/SE?

    - by Wulf
    What basic physics principles do software engineers and/or computer scientists use to help solve specific or common problems? The first one that came to my head was creating a Physics engine for a game; physics is involved, as it requires knowledge of: Forces and Motion: Kinematics, Dynamics, Circular Motion However, I need another example, but haven't come across one that involves basic physics. Please consider the following basic physics (grade 12 level) concepts: Energy and Momentum: Work and Energy, Momentum and Collisions, Gravitational and Celestial Mechanics Electric, Gravitational & Magnetic Field: Electric Charges and Electric Field, Magnetic Fields and Electomagnetism The Wave Nature of Light: Waves and Light, Wave Effects of Light Matter-Energy Interface: Einstein’s Special Theory of Relativity, Waves, Photons and Matter, Radioactivity and Elementary Particles I will be happy with any response; Keywords for google, names of methods like raycasting, etc.

  • Where is a Web Development Career fueled by Passion?

    - by JMC Creative
    Quick Background Since learning basic html 5 years ago, I've become completely obsessed with the technology, the logic, and the thrill of solving problems involved with building websites. I am still stuck at a thoroughly non-programming type job, but would really like to move into the field of web programming/design. I have no educational background in the field (was trained as a fine artist and tutor), but in the past few years have progressed fully self-taught (and self-motivated) from html to css to php, mysql, jquery, and am now building rich web applications. The Question How can I prove to a company that even though I have no education, I have a passion to learn whatever is thrown my way? ...That essentially I would come at every issue with not only knowledge, but with a passionate desire to solve it, whether that means tackling a new language or debugging code for hours at a time? p.s. Sorry for the stupid title.

  • Where to start in creating a massive multiplayer 3D Java game [on hold]

    - by user1373771
    I am planning on creating a massive multiplayer world and I am wondering where to start. I am quite inexperienced in the field of Java but I have researched into it and learned that it is perhaps my best bet in creating this project is Java for the fact that it has a much easier learning curve than C++ to beginners and still capable of holding massive amounts of players at a time. My question is simple: Should I start the game by creating a single player prototype and introducing multiplayer later as I become more experienced or start with multiplayer before I am completely experienced in the field. Thanks for your help!

  • battery icon / power indicator not shown in menu bar after upgrade to 12.04

    - by user488728
    since the upgrade from 11.10 to 12.04 the battery icon / power indicator is not shown any more in the menu bar. I went to 'system settings'--'power' and tried to set 'show battery status in menu bar' to 'always', however the selection button seems to be corrupt. Strangely, when I open the power settings dialog, the 'show battery status in menu bar' field is set to an empty string instead of showing one of the three possible choices. When I click on the small arrow next to it, the three possible choices are shown. Whatever I select, upon closing the settings dialog and reopening it, the selection field is back to empty. Please help. Thanks! HF

  • How to determine which cells in a grid intersect with a given triangle?

    - by Ray Dey
    I'm currently writing a 2D AI simulation, but I'm not completely certain how to check whether the position of an agent is within the field of view of another. Currently, my world partitioning is simple cell-space partitioning (a grid). I want to use a triangle to represent the field of view, but how can I calculate the cells that intersect with the triangle? Similar to this picture: The red areas are the cells I want to calculate, by checking whether the triangle intersects those cells. Thanks in advance. EDIT: Just to add to the confusion (or perhaps even make it easier). Each cell has a min and max vector where the min is the bottom left corner and the max is the top right corner.

  • Configuring Network without Default Gateway

    - by Homayoon
    I'm trying to connect my desktop and laptop using an ethernet connection. I usually configure network from the command line but this time I decided to give Network Manager a try, so I went to Network Connections, and selected manual IP configuration. At first I left the default gateway field blank, since I don't need a default gateway. Turned out network manager doesn't let me save the connection unless I enter that field, but entering a phony gateway messes up with my Internet connection. Anyway to do this setup?

  • Most important research article for software development [closed]

    - by Fabian Fagerholm
    Researchers all over the world collectively publish thousands of articles on software development topics every year, hoping to benefit practical software development in the long run. (Of course, some of them only publish to increase their publication count, but hopefully most still aim to advance the field.) But what is really useful for practical software development? Of all the research articles you have read, what do you consider being the most important one for the software development field? What is it about that article that makes it stand out as especially important in your view? Note: I deliberately chose the term "software development", but you can freely interpret it as "programming" or "software engineering", or anything else that fits into the "software development" category.
