• how much knowledge do you need to call yourself a programmer?

  - by nore

  There is a guy who calls himself c/c++ programmer, but what does he actually know? What knowledge about c++ does he have because there are so much to know about c/c++. So he knows the core language? He knows visual c++? He knows how to program with WIN API? He knows how to program in linux with gtk? Network programming? The real question is: What do you need to know, to be called a c/c++ programmer ,because I know c and I really do not feel like I own the power of programming... please illuminate my path.

• After a domain change, what can I do to recover lost traffic, rankings, impressions etc? [duplicate]

  - by Felix

  This question already has an answer here: How do I rename a domain and preserve PageRank? 3 answers I moved my site to a legacy exact-match domain I purchased about a couple of months ago. I have seen significant reduction in traffic, impressions, and rankings. I did all the right steps/best practices: change of address in GWT, map old site hierarchy and match to new site for 301 redirects etc. Indexation has gone through the Google process: old site has all but dissappeared from he index and new site is indexed, albeit with some 404 errors which I am addressing. Does anyone else who has gone through eh domain change process have any thoughts/advice? Thanks!

• Is it a good idea for exams to be done on a computer?

  - by vemv

  In some colleges students are let to use an IDE and Internet and in mine you have to write down your solution in paper. As far as I know, it's pretty much impossible to make a correct non-trivial program on the first try. I'd be fine with no using computers if my teachers assessed my approach instead my code -literally-... that's not the case unfortunately. Which ones are more usual, 'written' or 'coded' exams? And which way is the most adequate? Edit - question title changed (it used to be Should students have the right to do exams using a computer?)

• "Never do in code what you can get the SQL server to do well for you" - Is this a recipe for a bad design?

  - by PhonicUK

  It's an idea I've heard repeated in a handful of places. Some more or less acknowledging that once trying to solve a problem purely in SQL exceeds a certain level of complexity you should indeed be handling it in code. The logic behind the idea is that for the large majority of cases, the database engine will do a better job at finding the most efficient way of completing your task than you could in code. Especially when it comes to things like making the results conditional on operations performed on the data. Arguably with modern engines effectively JIT'ing + caching the compiled version of your query it'd make sense on the surface. The question is whether or not leveraging your database engine in this way is inherently bad design practice (and why). The lines become blurred further when all the logic exists inside the database and you're just hitting it via an ORM.

• Getting Started with 12.04 LTS Problems

  - by mark

  Okay previously I used ubuntu 10.04 in Desktops and Loved it! I bought a newer Toshiba Satellite with an i7 CPU, 8GB Ram, 1TB HD, first thing I tried to do was install Ubuntu 9 on it then I found out it was no longer Supported. (I gave my 10.04 disk away) So I tried installing Windows 7 and experienced SO MANY problems, I am going back to try 12.04. Starting all over again. After installing 12.04 Wireless was Detected yet said it was Disabled by a Hardware Switch. Went read through the Message Boards found Solution which was Sudo rf Kill All. Okay all excited I would finally get my Ubuntu to finally work I rushed back to my laptop from the internet cafe, and went looking for the TERMINAL input on my Ubuntu 12.04, and I cannot find the Terminal. If I can't find the TERMINAL how Can I enter any Sudo Stuff? So I guess the first question is Where is the Terminal Located in 12.04? Thank you.

• Poll: How long will you wait before using Solaris 11 on production systems?

  - by nospam(at)example.com (Joerg Moellenkamp)

  When Sun released Solaris 10, it was my first migration phase to a new Solaris major release while being part of Sun. At that time i heard a lot of comments between "Oh, we will install it on new systems on day 1" to "oh ... not that fast ... we will wait ... we are not that fast ... we will do it in a year". I would like to get some additional insight and so i set up the poll plugin for s9y to get the answer to the question "How long will you wait before using Solaris 11 on production system?". Thank you for your participation!

• Subdomains vs. URL Path in shareable links

  - by Adam Matan

  I am building a web application for questions and answers. Each question/answer page has all the required metadata for Facebook and Twitter, and we encourage users to share these pages. I have a dilemma regarding the shared link structure: Option 1 - subdomains Use a questions.example.com and answers.example.com, followed by an ID and optional text. The text is ignored by the request, which only takes the id into account. http://questions.example.com/<question_id>/<question_text> http://questions.example.com/12345/how-long-is-the-queue # Example http://q.example.com/12345 # Example Option 2 - URL path This is the format used by stackoverflow.com and trello.com: http://example.com/questions/<question_id>/<question_text> http://example.com/questions12345/how-long-is-the-queue # Example http://example.com/q/12345 # Example Server-wise, I can easily do both - I have a wildcard SSL certificate and Apache/NGinx configuration is pretty straightforward. Which option - subdomains or URL path - is preferred for shareble links?

• Looking for best approach to create new projects for enviroment specifics files

  - by Ness

  ClearCase Question... Overview of requirements: There are 3 diff environments (DEV, TEST and PROD) which have a folder called 'common' that users across all envs. There are multiple servers in those 3 envs and we want to store their server environment specific configuration files in Clearcase. The executables files are different for each environment. Thus there will not be cross delivery require between dev/test/prod. Any thoughts on how we can approach this? Is keeping it simplest is the best approach here? One component to one vobs as (DEV_Serv1, TEST_Serv1, PROD_Serv1, Dev_Serv2, Test_Serv2 and etc)? OR Have multiple components VOB? One other thing is developers here like to use snapshots views.

• chown select files only

  - by user114642

  I use the (excellant) unison to sync two file servers and I've just realised i've synced a number of files without using the switch in unison that maintains the file user ownership. these files now have a user of root (coz i have to run unison as root) Can I chown to a specified user BUT only change the files that now have the owner root and do so recursively in the directory in question? Sure i can but not sure of the arguments to "find files with owner 0 and change them to owner xxxx". THX for any help...

• What happens to my domain if the TLD fails?

  - by KingCrab

  First question, hopefully I don't mess this up. I have recently registered some domains on the basically brand new .directory gTLD. Because of operating costs to maintain a gTLD, it is assumed that many of the hundreds being rolled out this year and next will fail. I will admit I am not very knowledgable on how the TLD process works. What exactly does a new TLD failing mean? I realize that they lose ICANN accreditation, but does that just mean that they will be no longer be sold? If the .directory were to go under, would my .directory domains be affected? I bought it from domain registrar Gandi if that helps.

• Getting through a lengthy book?

  - by Mr_Spock

  This may seen like a weird question, but since we're challenged--as engineers--to constantly adapt to changing technologies, we always find ourselves buried in documentation. That said, we also need to consider that time is of the essence because people want their stuff fixed and improved with little hesitation if any. How do you get through lengthy manuals, books/manuals within a short period of time? Take for example: "The Linux Programming Interface," by Michael Kerrisk, which is roughly 1500 pages in length. How would you get through a monster of a book like this if you're pressed for time while still learning most of the material?

• XFCE4 Empty Volume Control Applet

  - by adamt

  I just wanted to ask, what could I mess up? My situation is this: In XFCE4.10 (!) on the panel0 I put the Indicator Applet. It always showed me the volume control and network icons. When I updated to 13.10 and after cleaned some stuff, removed some orphaned package, I noticed, the volume control applet is showing mute and if I clicked on it there is an empty drowdown menu like 10x5 px.. Now it became completely useless. So my question is WHAT should I reinstall or change to get the control work?.. :/ Thanks.

• Retrieve the coordinates of the *occluding* (closest/drawn) pixels during 3D overlap, using OpenGL?

  - by Big Rich

  Hi, Sorry if the question is not worded well, I'm a new to both 3D and OpenGL. How could I go about obtaining the 3D coordinates of the occluding object, at the point where occlusion is happening (i.e. the 'intersection' of the object in front/closest to the screen)? Just to offer a [very] rudimentary, visual, example, if you were to form an index-finger cross, with your right hand closest to your face, I'd like to know the coordinates of the part of your right finger which obscures the other finger (obviously back within the OpenGL context - no jokers ;-) ). If there is a way to find out both about the occluder (hider) and the occluded (hidden) objects in OpenGL, then that would be of great use, also. Cheers Rich

• How to deal with OOP design problems in interviews?

  - by haps10

  This is a question where I seek guidance from fellow/senior developers to get into my dream company - it's a pioneer in OOP and Agile. I've already failed once to clear an interview. One part I feel most challenging is to come up with a proper Object Oriented design(classes, interfaces, methods, interactions etc.) in a very short time for certain situations like Pacman, Game Of Life and so on. As the problems are unprecedented ones - my approach is mostly to try different things and then make decisions - which they feel is not clear and not what they expect from a developer with 5+ years of experience. I've already studied a few books on patterns, OOP - it didn't help me much and I think it'll take a bit more than that. Could some one please guide on what specifically shall I practice so that I can do better at design problems as above. I want to refine my approach and have a better thought process.

• C++ linkage error . What am I doing wrong ? [migrated]

  - by nashmaniac

  So, this is the first time I actually separated a single program into a header and two .cpp files . But I think I am getting an linkage error . Heres how the directory looks . (heres a link to my image I dont have enough rep to post image in the question) http://i.stack.imgur.com/sbT4V.png The main.cpp is my main source file where all the calling functions and other important stuff goes . In functions.cpp I have all my functions , in the coordin.h file I have the function prototypes and structures and Constants . Everything is ok no typo nothing I have checked everything . But I am getting an undefined reference to function error. I have included the coordin.h file too . Do you think the functions.cpp file needs to go somewhere else I mean is the compiler not looking inside that file ? Thanks !

• What do you use to create sprite graphics? [closed]

  - by SimpleRookie

  Possible Duplicate: What tools do you use for 2D art/sprite creation? What do you folks suggest for creating sprite graphics and sprite sheets? I fiddle with pixelformer and tilestudio. Pixelfromer has a kicken interface, it is quick and easy to make graphics, but a bit cumbersom if you want to make a spritemap. Tile Studio is a interesting mix or tiles and maps, but it is a bit buggy and basic. The Adobe series, just don't really seem to handle tiny graphics well. (there is a previous posting of this question existing, but it is a year old and I was hoping for further/updated input from the community)

• Multiple ( V- / I- ) Buffers, is it sane?

  - by Techie

  Currently I am developing an RTS game using XNA ( / ANX.Framework ). There is one thing bothers me. I am not sure in what way or how to organise Buffers. Should I use a new Vertexbuffer for any object ( e.g. a Char, a Table, an model ) or is it better to use ONE HUGE/ BIG Buffer to store any geometry in? I am still new to 3D Programming though I finished yet couple games using DirectX 9. Well, I hope this question qin't a duplicate and I appreciate any answer leading me into the right direction.

• Should I keep separate client codebases and databases for a software-as-a-service application?

  - by John

  My question is about the architecture of my application. I have a Rails application where companies can administrate all things related to their clients. Companies would buy a subscription and their users can access the application online. Hopefully I will get multiple companies subscribing to my application/service. What should I do with my code and database? Seperate app code base and database per company One app code base but seperate database per company One app code base and one database The decision involves security (e.g. a user from company X should not see any data from company Y) performance (let's suppose it becomes successful, it should have a good performance) and scalability (again, if successful, it should have a good performance but also easy for me to handle all the companies, code changes, etc). For the sake of maintainability, I tend to opt for the one code base, but for the database I really don't know. What do you think is the best option?

• Installing Ubuntu before or after upgrading from Vista to Win 7?

  - by amh

  I just got a new SSD hard drive for my thinkpad laptop. I just installed Vista with the factory CDs. On my old OS, my main OS was Ubuntu but I do want to keep Windows on a separate partition as a dual booth system. I definitely want to upgrade to Win 7 though and I will get it in a few days. My question is: should I install Ubuntu now and then upgrade to Win 7 in a few days? or is that going to mess up with the grub (or something else)? If that is the case, then I'd rather wait to install Ubuntu until after I upgrade to Vista. P.S. I know that probably any kind of mess done by the Win upgrade could be fixed, but I just want to avoid wasting time.

• How to maintain a file's 'last modified' date ?

  - by Will.

  I'm copying files and folders over from one filesystem to another (both are ext3) via cp in the terminal. The 'date modified' on all of the files are being changed to the current time although I am not modifying the folder or the files. I'd like for them to keep their existing 'last modified date' which vary within the past 5 years. I am not interested in changing them to a specific date as described this previous question, but to maintain the existing 'last modified' date. I'm using 12.04.

• No splash screen on hibernate

  - by Marky

  Hibernate is working fine. A bit slow when resuming from a hibernate but I can bear with it just so that I have all open applications on the desktop as I left it. Then again the "slowness" might be because of the 4GB RAM, although I'm assuming only what is used gets swapped and not the entire memory. Going back, my question is has anyone been able to make Ubuntu show a splash screen or some kind of indicator/progress bar to show while hibernating or while resuming? I remember with SuSE on my HP Compaq Presario notebook it had messages appear during and after. Better than nothing, I guess. Thanks in advance! :D

• When to Use workflow engines?

  - by A01_

  I'm totally new to this concept from design perspective. I've worked in past on some of the workflow engines as programmer but never had a clarity on why we chose the work-flow engines in first place. And as programmer I know that there are at least 100 ways to do anything when you are writing code but only few of the ways are the best! I still don't understand which use cases are best solved by workflow engines (or rather their concept) than designing a good DI enabled application. I'm looking for any general characteristics of domain-neutral use cases, where work-flow engines are one of the the best options. So my question is: What are general characteristics of a requirement which can be taken as a signal for opting for a good workflow engine and coding around it? Cheers!

• Translating with context

  - by translate

  Is there a way I can see the result of my work while I am translating? It is difficult to translate without context. If I could see how my work will appear while I am doing it, translating is much easier. Edit from Oli: I understand this question to be from somebody who is translating an application. Translators often only have a list of phrases to translate without being able to see where those phrases are used in the app. This person wants a way to quickly locate a string inside an application so they can understand the phrase better and provide the best possible translation.

• Ubuntu 12.04 installer does not recognize Windows 7

  - by trainofk

  I recently purchased an ASUS N56VZ-ES71 laptop which came with Windows 7 Home Premium installed on it. I wish to dual boot Windows 7 and Ubuntu 12.04 on it. I shrank the hard drive partitions to leave about 150 GB unallocated for Ubuntu 12.04. When I boot the Live CD of Ubuntu and attempt to install, the installer does not recognize any other operating systems. Through reading a few questions, I have found that this is due to a GPT partitioning table that Windows uses. I ran boot-repair as per other threads' suggestions. This was my output: http://paste.ubuntu.com/1176988/ I suppose my question is: how do I proceed in order to get the installer to recognize Windows, so that I don't have to erase the current partition table and can get a safe install? Thanks in advance.
