  • Dealing with "Coder's Block" (or blank form syndrome)

    - by robsoft
    I know this is the sort of somewhat open-ended question that we're discouraged from asking, but there are lots of open-ended questions around already, and this is something quite relevant to me right now. Do you ever get those times when you're about to start work on a new function/feature of an established system, and you get "coder's block"?. It's like a mental freeze at the sight of a large, completely unpopulated dialog, or an empty code file with just the stub reference headers etc. Do you ever have that 'ulp' moment that seems to sap all your momentum and leave you wide open to distractions (surfing the web for inspiration, checking out 'crackoverflow' etc)? Not that I'd wish it on anyone, but hopefully some of you do, and hopefully some of you can suggest tips or strategies for overcoming the situation, regaining your momentum and becoming productive again. I usually try to reduce what I'm about to do down to absurdly small steps, in the hope that as the job becomes just a series of 'doh' tasks, I'll kickstart myself into working through them. However sometimes, particularly when a deadline is looming, I'll get overwhelmed by this approach as I realise I probably don't have enough time to do all of those tiny steps properly. Those are the darkest moments, (often literally) just before dawn! This situation can be particularly crippling if you mostly work alone, too. Any thoughts or suggestions? Any methods that you found helpful yourself?

  • Good locations worldwide for a coder gypsy wannabe

    - by fung
    Yes, this is not programming related but please bear with me =). I run a small niche SaaS business. Lately I've been thinking of traveling and experiencing life in other places. Would really appreciate suggestions for good places a developer could relocate to. In particular I'm looking for a place that: Has good internet connection (cheap stable broadband, lots of places that provide free wifi, etc.) Low cost of living (rent and food fairly cheap). At least half of the population speak English. Has a local courier agent (DHL, Fedex, any...). The government allows for extended stay of foreigners. I'm thinking of staying for about 6 months at each location and maybe doing it for 3 years. So looking for 5 to 6 locations in total. So if any of you think you're staying in a place that would be great for a visiting developer then please shout out. Include as detailed a description as possible. And include any cons about the place if there are. The only place that pops to mind right now is Bali =). Isle of Skye also seems interesting but I think immigration is tight and cost of living would definitely be higher. Thanks in advance for suggestions =)

  • Improving as a coder with respect to design.

    - by dmarakaki
    As a soon-to-be computer science graduate, I have to come realization that I have a long way to go when it comes to the overall design of an application. After spending many semesters of programming from the hip I have come to appreciate the mulling over the needs of an application before diving head first into the coding portion. My question is to the intermediate and expert programmers, how can I improve in the area of the design phase of development?

  • Key Coder/Observer example for Iphone

    - by ReduxDJ
    I'm trying to implement KVO into an application, yet, I've followed the documentation provided by Apple, however I can't get it to work. I'm hoping to see a bare minimal example of how to use this with my NSObjects. My use case, is I want one item in a table-cell to update without loading the entire data in a tableView because I am loading images from URLs and I don't want to reload all of the image, while I am polling a server. Thanks,

  • Git: Help an SVN novice translate trunk/branch concepts to Git

    - by Jasconius
    So I am not much of a source control expert, I've used SVN for projects in the past. I have to use Git for a particular project (client supplied Git repo). My workflow is as such that I will be working on the files from two different computers, and often I need to check in changes that are unstable when I move from place to place so I can continue my work. What then occurs is when, say, the client goes to get the latest version, they will also download the unstable code. In SVN, you can address this by creating a trunk and use working branches, or use the trunk as the working version and create stable branches. What is the equivalent concept in Git, and is there a simple way to do this via Github?

  • objective-c Novice - Needs help with global variables and setter method

    - by user544006
    I am creating a quiz app which has 2 views, MMAppViewController and a subview Level1View. I have declared NSInteger property "theScore" in the MMAppViewController view and have synthesised it. In my Level1View when they answer a correct question the "theScore" int will increase by one. The score has to be a global variable because when you reach so many points it will unlock the next level. For some reason in my switch statement it only lets me use the setTheScore method once. I am getting errors for every other set method in the switch statement. Error: "Duplicate label setTheScore". The statement is in the pushButtonAnswer method: setTheScore: theScore++; Here is my code: #import "Level1View.h" #import "MMAppViewController.h" @implementation Level1View @synthesize answer; @synthesize question; @synthesize userAnswer; @synthesize theScore; @synthesize score; int questionNum=0; NSInteger score=0; NSInteger theScore; BOOL start=FALSE; BOOL optionNum=FALSE; -(IBAction)pushBack{ [self dismissModalViewControllerAnimated:YES]; } -(IBAction)pushButton1{ optionNum=TRUE; labelAnswer.textColor=[UIColor blackColor]; userAnswer=@"1"; [labelAnswer setText:(@"You chose 'A'")]; } -(IBAction)pushButton2{ optionNum=TRUE; labelAnswer.textColor=[UIColor blackColor]; userAnswer=@"2"; [labelAnswer setText:(@"You chose 'B'")]; } -(IBAction)pushButton3{ optionNum=TRUE; labelAnswer.textColor=[UIColor blackColor]; userAnswer=@"3"; [labelAnswer setText:(@"You chose 'C'")]; } -(IBAction)pushButtonAnswer{ labelAnswer.textColor=[UIColor blackColor]; switch (questionNum){ case 1: if(answer==userAnswer && optionNum==TRUE){ labelAnswer.textColor=[UIColor greenColor]; [labelAnswer setText:(@"correct")]; [self hideButtons]; score++; [self setTheScore: theScore++]; } else if(optionNum==FALSE){ [labelAnswer setText:(@"Please choose an answer below:")];} else{ labelAnswer.textColor=[UIColor redColor]; [labelAnswer setText:(@"wrong")];} [self hideButtons]; break; case 2: if(answer==userAnswer && optionNum==TRUE){ labelAnswer.textColor=[UIColor greenColor]; [labelAnswer setText:(@"correct")]; [self hideButtons]; score++; [self setTheScore: theScore++]; } else if(optionNum==FALSE){ [labelAnswer setText:(@"Please choose an answer below:")];} else{ labelAnswer.textColor=[UIColor redColor]; [labelAnswer setText:(@"wrong")]; [self hideButtons];} break; case 3: if(answer==userAnswer && optionNum==TRUE){ labelAnswer.textColor=[UIColor greenColor]; .... And #import "MMAppViewController.h" #import "Level1View.h" @implementation MMAppViewController @synthesize theScore; NSInteger score; -(IBAction)pushLevel1{ Level1View *level1View = [[Level1View alloc] initWithNibName:nil bundle:nil]; [self presentModalViewController:level1View animated:YES]; theScore++; } -(IBAction)pushLevel2{ //Level1View *level1View = [[Level1View alloc] initWithNibName:nil bundle:nil]; //[self presentModalViewController:level1View animated:YES]; NSInteger *temp = Level1View.score; //int theScore=2; [labelChoose setText:[NSString stringWithFormat:@"You scored %i", theScore]]; } Does anyone know why i am getting these errors and if I am coding this correctly?

  • Java multidimensional array and scanner novice Q

    - by Max
    I'm new to Java and trying to in essence implement a grid with a character, and if the user inputs 'w' 'a' 's' or 'd' the character moves up/down/left/right within the plane. I created a multidimensional array sized 10x10 public static String[][] grid = new String[10][10]; And then just used a for loop to print "*"s in a 10x10 grid, except for grid[a][b] which is equal to character "A" i.e. my thing to be moved around. That seemed to work alright, then I needed to detect the 'wasd' input from the user so I set up a: Scanner in = new Scanner (System.in); while (in.hasNext()) And I had then: String s = in.next(); char ch = s.charAt(0); switch (ch) but I couldn't make this work, and it wasn't because I didn't complete the "switch" statement, I did, I just see it void copying and pasting the entire thing. I'm sure its incredibly easy slight thing I am missing, can you please point it out for me?

  • Hostname confusion (Ubuntu Server 10.04)

    - by letseatfood
    I have just setup Ubuntu 10.04 Server Edition. I have been following this tutorial. The DNS information seems to be setup correctly now, but I am confused about the hostname. Currently it is laughingbuddha.home. That is a name I created. Now, I am mainly not sure how to connect from another computer on my network. I basically want to be able to put PHP files on the server box and then test them via a web browser on my other computer. So, I think I digressed from my first question, but would somebody please help me figure out if the hostname is okay for doing what I need to do? Thank-you!

  • SQL - re-arrange a table via query

Is there a SQL technique to make this easy?

  • Which adjustable ergonomic keyboard do you recommend to a fellow coder and why?

    - by thefonso
    My beloved Goldtouch has died (a moment of silence)....the hinge at the middle which allows you to adjust the board finally broke and the manufacturer does not do repairs for free. I'd have to buy a new board. So...since this I'm in the market for a new keyboard and I'm looking for an adjustable one comparable or better to the Goldentouch. I post this question to all you coders out there. Which adjustable ergo keyboard do you recommend to a fellow coder and why?

  • Would a cut and paste coder ever get past a job interview?

    - by bigdave
    As a long time cut and paste coder I never committed much of the syntax of a language to memory. Even worse, I now use google to solve many of the coding problems which are of the type typically used in job interviews. This has greatly increased my productivity, the quality of the end result and stops me perpetuating the same bugs across all my code. However it means I don't actually remember the detail of the solution. For some reason in a job interview "I would look that up on google" does not seem to be the right answer. Am I better off in the interview to pass no comment on my coding style and simply pull out an iPad and produce the solution?

  • Quel Environnements de Développement Intégré utilisez-vous pour coder avec Symfony, le framework MVC libre en PHP ?

    Quel EDI utilisez-vous pour coder avec Symfony ? Cela fait déjà un petit temps que je développe avec symfony, en utilisant un bon vieux Notepad++. Et je remarque que, pour le C++, je code quand même bien plus vite avec un EDI plus que correct (Visual Studio) qu'avec Notepad++. Ce n'est pas le premier que je tente d'utiliser mais c'est le seul qui me convient. J'ai déjà essayé NetBeans avec support de symfony, mais je n'ai pas vraiment réussi à le prendre en main, pas hypra intuitif, etc. Ce qui fait que je suis retourné vite fait à mon Notepad++. Mais c'était au tout début du support de symfony (6.5, il me semble). Depuis, on en est à la 6.9 (7.0 en beta), est-ce que ça vaut la peine de réessayer cet EDI ? ...

  • Best practices for team workflow with RoR/Github for designer + coder?

    - by Josh
    My friend and I have started to try to collaborate on some projects. For background, I come from a PHP/Wordpress/Drupal coding background, but recently I've become more experienced with the RoR framework, while he is more experienced as an HTML/CSS designer, working with PHP and WordPress. We're both relatively new to RoR I think, and so we're trying to figure out our collaborative workflow, but we have no idea where to start. For instance, we were trying to figure out how he could do some minor edits to the CSS file without having to do a full RoR deploy on his box. We still haven't figured out a solution, so I think it's best if we start to set some sort of workflow based on best practices. I was wondering if you guys have any insight or links to articles/case studies regarding this topic?

  • What are general guidelines and advices to estimate how much you should charge for a project, being a novice freelancer?

    - by Dokkat
    I am an experienced programmer but completely new to the market. Someone wants me to do a project for them, but I do not know how much it is worth. What are general guidelines/advices for finding what a project is worth on the market? If I can ask here about this particular one, it is a HTML5 site with a login/register form and a video player that has to play a lecture video and powerpoint slides synchronized. They'll give me the video, the audio the powerpoints. I should also do some editting on the video before.
