• What is a programmer's life like?

  - by Zee JollyRoger

  Imagine like an 8-hour long video of any "typical/average" programming job. What is it like? Before I get myself involved in that path, what can I expect? I am interested in gathering first-hand information and accounts of the typical life of a programmer. My goal is to grasp the fundamental concepts of working in the professional field of programming. I just want to "see" into what it is/means to come to an entry-level programming job and program. See what kind of skills, mentality, expectations, and such are required.

• Best way to plan a task ?

  - by Indigo Praveen

  Hi All, As I am very new to programming, I am very curious about learning the best ways/practices of programming. Whenever I want to write any program , I strat directly with coding while some guys say that you should plan your program first before starting the code. But I don't understand the real value of creating the class diagrams and all that kind of stuff coz I think that ultimately I have to write the code. Can you guys please share your experiences about how you are doing your programming means what is your first step when you start an application.

• Project Idea with Hadoop MapReduce

  - by Aditya Andhalikar

  Hello, I learnt Hadoop a few months back and managed to do a very introductory programming project on it. I want to do a small - medium sized project or series of small programming assignments with Hadoop. I have seen lot of ideas around but I dont see anything that can be finished in about 60-70 hours of work so a pretty small scale project as I want to do that in my spare time along with other studies. Most project ideas I have seen sort of large to go on for 2-3 months. My main objective out of this exercise to develop good expertise in programming with Hadoop environment not to do any research or solve specific problems. I see Hadoop being used lot of with webservices maybe that would be an interesting track for small projects. Thank you in advance. Regards, Aditya

• ASP.NET AJAX or jQuery (UpdatePanel/ScriptManager or UFrame/jQuery.ajax)

  - by Mark Redman

  Hi, We use the asp.net UpdatePanel and the ScriptManager/ScriptManagerProxy for ajax related functionality; reducing full page refreshes and calling WCF Services respectively. we also use jQuery and plugins for some parts of the UI. We have had some issues with javascript library related conflicts, but have come across some posts indicating that there is a lot more overhead using the UpdatePanel. I have found some limited reference to UFrame: http://www.codeproject.com/KB/aspnet/uframe.aspx www.codeplex.com/uframe Is this a commercially viable replacement for the asp.net UpdatePanel? We use a ScriptManagerProxy to reference WCF services and easily create and use a proxy to call the various WCF service methods. Would using jQuery ajax be a more efficient solution here? We have got this working well on various browsers but now seem to be getting some security related issues (as seen in FF Firebug: Access to restricted URI denied" code: "1012) which seem to have started since using jQuery a lot more. Is it possible/viable to not use ASP.NET Ajax at all?

• ValidateInput Attribute Doesn't Seem To Work in ASP.NET MVC

  - by JC Grubbs

  I'm trying to get around the "potentially dangerous Request.Form value" error and I'm having no luck. Yes, yes, I've read all the other StackOverflow related questions and none of them seem to get me closer to an answer. I am using [ValidateInput(false)] on all related controller actions...and I've checked many times. I'm using ValidateRequest='false' in all the related ASPX views. I am using ASP.NET MVC 2 Preview 1, but I don't think that's an issue since the error is being generated lower in the framework; Page.ProcessRequest to be exact. I can't see anything I'm doing wrong, I even set <page validateRequest='false'> in the web.config and that didn't solve it either. HELP!!!!!

• Is being a programmer a younger person's job?

  - by Saobi

  After you get old, say past 30 or 40. Can you still keep up with the young coders from your company, those fresh out of school, who can code for 15+ hours on 10 cans of redbulls (most people in Google, Facebook, etc) ? And given the lightning speed with which today's programming frameworks and architectures evolve, can you keep up with the most up to date stuff and be as proficient at them as the next college grad? I know for jobs like unix/c/embedded programming, it might be that the older the better. But for programming jobs in say web development, social media, search engine technology, etc. Do you become less and less competitive career-wise versus youngsters? For example, most coders in Google and Facebook, I believe are under 25 years old. In other words, once you reach a certain age, would it be unwise to continue to be a coder, and is it better to try becoming a project manager or architect?

• What first game did you program, and did it make you a better developer?

  - by thenonhacker

  What first game did you program? Name your game, the OS and language, and even a Website URL to get your game. Old DOS Games and Flash Games with ActionScript are allowed. Game kits are allowed, too. ...and did it make you a better developer? Programming games can be addicting, and it will bring out the best in us as we create our first game. What lessons did you learn form most? Algorithm and/or AI's? Graphics? User Interface? File Formats and Data Storage? Project and Time Management? Can you say that because you practiced programming by creating this game, you became more immersed with the programming language you used and helped you become a better developer?

• Great computer-science speeches

  - by sub

  I've looked into some questions here where the "best" programming books are listed and then thought why there isn't a question concerning speeches yet. I think that speeches or presentations from developers or even creators of programming languages which were or are heavily used at some point are particulary interesting. One of my favorite speeches was recommended to me by someone here on SO: The future of C# I also like Guido van Rossum's speeches but he sometimes seems pretty nervous. Another in my opinion good presentation would be the Google tech talk about Go. Which (recorded) programming presentations/speeches are worth watching? edit: Made this a community wiki as the answer would probably be a pretty long list.

• How to do "See Also" to a book using doxygen

  - by Paul J. Lucas

  The Javadoc @see allows a simple string as an argument to refer to something like a book, e.g.: @see "The Java Programming Language." As far as I can tell, the Doxygen \see offers no equivalent. Is there any way to have a book reference generated in the documentation, e.g.: See Also The C++ Programming Language, Bjarne Stroustrup, Addison-Wesley, 2000, section 19.4.1: The Standard Allocator ? Clarification This question is about how to do a "See Also" as part of a comment, e.g.: /** * Allocates memory in an amazing way. * \param size The number of bytes to allocate. * \return Returns a pointer to the start of the allocated memory. * \see MyOtherClass::alloc() * \see "The C++ Programming Language," Bjarne Stroustrup, Addison-Wesley, 2000, * section 19.4.1: The Standard Allocator. */ void* my_alloc( size_t size ); Of course the above does not work in Doxygen. Note that if there are multiple \see tags, they should be merged into a single "See Also" section (like the way \see normally works.

• How to virtually delete data from multiple tables that are linked by a foreign key ?

  - by Shantanu Gupta

  I am using Sql Server 2005 This is a part of my database diagram. I want to perform deletion on my database which will start from tblDomain up tp tblSubTopics. Consider that each table has IsDeleted column which has to be marked true if request was made to delete data. But that data shoud remain their physically. Tables which will have IsDeleted Column are tblDomain tblSubject tblTopic tblSubTopic Now I want, if a user marks one domain as deleted then all the refrence field should also get marked as deleted. i.e. 1 domain is related to 5 subjects, those 5 subjects are related to 25 topics, those 25 topics are related to 500 subtopics and so on. Then how should i mark all these fileds as Deleted. ?

• sql server 2005 - return single row when 2 records in right table

  - by Peanut

  Hi, I have two related sql server tables ... TableA and TableB. ***TableA - Columns*** TableA_ID INT VALUE VARCHAR(100) ***TableB - Columns*** TableB_ID INT TableA_ID INT VALUE VARCHAR(100) For every single record in TableA there are always 2 records in TableB. Therefore TableA has a one-to-many relationship with TableB. How could I write a single sql statement to join these tables and return a single row for each row in TableA that includes: a column for the VALUE column in the first related row in table B a column for the VALUE column in the second related row in table B? Thanks.

• Pomodoro technique & other ways to increase personal productivity

  - by Jayson

  I recently came across the Pomodoro Technique as a way to increase productivity, get in the zone, and in general feel a sense of accomplishment at setting some short programming goals and achieving them. So far I have enjoyed it and the sense of accomplishment I get after seeing a bunch of short goals add up at the end of the day to a lot of work done on a programming project. What other ideas, similar or not, add a little variety to achieving goals, personal productivity, get in the programming zone, and so forth? What ideas or techniques are expressed formally, such as those in the Pomodoro paper, rather than trite maxims?

• Indexing SET field

  - by Dienow

  I have two entities A and B. They are related with many to many relation. Entity A can be related up to 100 B entities. Entity B can be related up to 10000 A entities. I need quick way to select for example 30 A entities, that have relation with specified B entities, filtered and sorted by different attributes. Here how I see ideal solution: I put all information I know about A entities, including their relations with B entities into single row (Special table with SET field) then add all necessary indexes. The problem is that you can't use index while querying by SET field. What should I do? I can replace database with something different, if that'll help.

• looking for a set union find algorithm

  - by Mig

  I have thousands of lines of 1 to 100 numbers, every line define a group of numbers and a relationship among them. I need to get the sets of related numbers. Little Example: If I have this 7 lines of data T1 T2 T3 T4 T5 T6 T1 T5 T4 T3 T4 I need a not so slow algorith to know that the sets here are: T1 T2 T6 (because T1 is related with T2 in the first line and T1 related with T6 in the line 5) T3 T4 T5 (because T5 is with T4 in line 6 and T3 is with T4 in line 7) but when you have very big sets is painfully slow to do a search of a T(x) in every big set, and do unions of sets... etc. Do you have a hint to do this in a not so brute force manner? I'm trying to do this in python. Thanks

• Vim Editor is very smart?

  - by Narek

  I am programming in C++ or Java. So I want to use Vim editor, because it is very flexible. I have heard that I can configure the Vim editor to be able to go from object to the definition from function to the definition from class name to the definition Do we have any professional Vim-er that could tell me how exactly to configure Vim for that? Thanks in advance. P.S. In case readers will consider this question is not connected with programming, I would say that this is improving speed of programming. So it is a help to the programmer. So please don't close this question. EDIT: Also I would like to know how vim works with code completion and can vim hint the list of methods that are available for the certain object? If yes, then I would like to know how to configure these options too?

• How do I get started on a bigger project?

  - by Axilus

  Hey guys, Most of the time I have been programming little apps either for myself or for the benifit of learning. Now that my programming skills are considered somewhat intermediate, I was wondering how I would tackle a large programming project. Lets suppose I wanted to make an application that has a lot of features and is intended for the use of others and not just myself; how do I go about planning for such projects? Do I just jump in and start coding the thing or is there some sort of recommended process? Thanks in advance :D

• Using both RolesAllowed and Transactional in beans

  - by Laran Evans

  I have some beans which contain methods which are annotated with both @RolesAllowed and @Transactional. I have one Spring config file which utilizes a BeanNameAutoProxyCreator for Security related beans and another Spring config file which utilizes a BeanNameAutoProxyCreator for Transactional related beans. The problem is that some beans contain both security as well as transactional-related beans. So Spring creates proxies for one set of beans. It then tries to create proxies for the other set of beans. When it does, it tries to create proxies of the proxies and bombs out. Has anyone tried to configure both security and transactionality in the same beans via Spring? What's the trick? Thanks.

• Win32: No Window Appears

  - by SoulBeaver

  I was programming the example code from Frank Luna's book "Introduction to 3D Game Programming with DirectX 10". The code is the first Win32 example in the Appendix A: Windows Programming section. Right now, the program compiles under both VC++ 2008/2010, but no window appears, although the debug session has started and I have to forcefully close it. I have no idea where it is, I'm not using Win32 Console mode, I have closed all other windows and no other IDE or session of VC++ is running. Any idea why this might be happening? PS: I have also checked my Processes. It is indeed running.

• Inheritance in tables - structure problem

  - by Naor

  I have 3 types of users in my system. each type has different information I created the following tables: BaseUser(base_user_id, username, password, additional common data) base_user_id is PK and Identity UserType1(user_id, data related to type1 only) user_id is PK and FK to base_user_id UserType2(user_id, data related to type2 only) user_id is PK and FK to base_user_id UserType3(user_id, data related to type3 only) user_id is PK and FK to base_user_id Now I have relation from each type of user to warehouses table. Users from type1 and type2 should have only warehouse_id and users from type3 should have warehouse_id and customer_id. I thought about this structure: WarehouseOfUser(base_user_id,warehouse_id) base_user_id is FK to base_user_id in BaseUser WarehouseOfTyp3User(base_user_id,warehouse_id, customer_id) base_user_id is FK to base_user_id in BaseUser The problem is that such structure allows 2 things I want to prevent: 1. add to WarehouseOfTyp3User data of user from type2 or type1. 2. add to WarehouseOfUser data of user from type3. what is the best structure for such case?

• SRAM Cell Diagram - Can someone explain this a bit more clearly? ( From COMP1917 @ UNSW: Lecture 2 o

  - by Kristina

  I've begun watching a series of first year lectures from the University of New South Wales (UNSW) in Australia, and I'm a bit perplexed by the instructors explanation of how an SRAM gate works. I realize this isn't exactly "programming-related" but since it comes from a series of lectures relating to computing and programming, I thought StackOverflow may be able to help (reddit failed me entirely). In this lecture beginning at around 32:12, Richard (the lecturer) tries to explain how a "latch gate" works within SRAM. Although his students seem to keep up, I feel I'm missing something crucial which is preventing the concept from really "clicking" in my brain. For convenience, I've added the image from the video below: Thanks in advance for any help you can provide, but if this question doesn't fit your view of "programming-related" could you please provide an alternate forum for this in a comment when you cast your close vote? Thanks!

• A good F# codebase to learn from

  - by Lucas

  Hi all, I've been teaching myself F# for a while now. I've read Programming F# by Chris Smith (great book) and I've written a few small scripts for getting the job done here and there. But IMO the best way to learn a new programming language—and more importantly, the idioms that come with it—is to read a good open source codebase written in that language. Naturally, writing code in that language is crucial, but in the beginning, you're basically struggling with your own ignorance about how things should be done. You could perform certain tasks one way or the other, but it takes experience to realize the flaws and virtues of each. Even after you've gotten a firm grasp of how things work, reading the code of people who have an even firmer one helps a great deal. Most would agree that the most insightful parts of any learn-a-programming-language book are the code examples, and reading a well-written open source codebase is the next level of that. So are there any out there for F#?

• is it better to use a "natural" language to write code?

  - by M.H

  I recently saw a programming language called supernova and they said in the web page : The Supernova Programming language is a modern scripting language and the First one presents the concept of programming with direct Fiction Description using Clear subset of pure Human Language. and you can write code like: i want window and the window title is Hello World. i want button and button caption is Close. and button name is btn1. btn1 mouse click. instructions are you close window end of instructions my question is not about the language itself but it is that are we need such languages and did they make writing code easier or not?
