  • How to see "anti if" movement and its gaol?

    - by Vijay Shanker
    I have a developer for last 3 years, have been using if-else or if-else if statements a lot in my programing habit. And today, I found This link. One obvious sample i put here public void doSomthing(String target, String object){ //validate requests if(target != null && target.trim().length() < 1){ //invalid request; } //further logic } Now, I have seen this sort of check all over the places, libraries. So, I wanted to have a discussion about the worthiness of such a movement. Please let me know your views.

  • How do you deal with the more mundane parts of programming tasks?

    - by Uri
    My experience as a developer is that many projects or tickets are a mix of a short and focused very interesting task (e.g., designing some API or a platform to solve something) and a lot of repetitive and mundane tasks that cannot be automated (such as certain refactorings to use the API or platform, implementation of certain tests, some GUI handling, etc). I believe that this is the nature of our profession, unless we are high-level architects or managements and can delegate this work. The only item in my personal arsenal when dealing with these tasks is to devote some of my attention to radio or audiobooks (preferably not in English as I find it hard to concentrate on two "streams" of English at the same time). I maintain sufficient attention to carry the task and don't lose concentration as fast. I'm wondering how others cope with these and maintain concentration.

  • Alter top and bottom borders of Dojo/Dijit Dialog and ContentPane

    - by Joe Zitzelberger
    I have a Dojo/Dijit Dialog that contains a FORM. There is a top border between the title bar and the content, and a bottom border below the content. Both are about 19 or 20 pixels high and colored #eeeeee. I can't find these borders in the CSS anywhere -- actually, neither can the IE Developer Toolbar -- they just don't seem to exist as elements. I suspect that Dijit is adding these programatically. Is there any way to just remove these borders? I just want my content to consume all of the dialog area below the title bar. TIA

  • What is the precedence of characters when sorting in MySQL, PHP, or just in general?

    - by FireCoding
    Question: Where can I find the precedence of characters when sorting in MySQL, PHP, or just in general on Linux and Windows OS? For example, everybody knows that a comes before b when performing an ascending sort on a string in MySQL. But what about other characters? Does the dollar-sign $ come before asterisk * ? Does a space come before an exclamation-mark? etc... What dictates the sort order? Does it use underlying ascii / UTF-8 values? Is it different for different technologies? Technologies to consider: Databases - MySQL / SQL / SQLite / Oracle / etc Programming languages (for string-sorting functions) - PHP / Javascript / ASP.NET / Visual C# / Python / Ruby / Objective C OS (i.e., sorting files by filename) - Windows / Linux / MacOS / iOS / Android

  • Why do they initialize pointers this way?

    - by Rob
    In almost all of the books I read and examples I go through I see pointers initialized this way. Say that I have a class variable NSString *myString that I want to initialize. I will almost always see that done this way: -(id)init { if (self = [super init]) { NSString *tempString = [[NSString alloc] init]; myString = tempString; [tempString release]; } return self; } Why can't I just do the following? -(id)init { if (self = [super init]) { myString = [[NSString alloc] init]; } return self; } I don't see why the extra tempString is ever needed in the first place, but I could be missing something here with memory management. Is the way I want to do things acceptable or will it cause some kind of leak? I have read the Memory Management Guide on developer.apple.com and unless I am just missing something, I don't see the difference.

  • Are there any good materials or examples on creating a custom Designer in the Delphi IDE

    - by Mark Elder
    I am working on creating a custom form designer in the Delphi IDE. I'm trying to use the RegisterCustomModule, TBaseCustomModule, and ICustomModule functions, classes, and interfaces. My first question on this pointed me to the Delphi Developer's Handbook and the idea that I could even create a custom form designer. However, that book seems to be all Delphi 3 information and things have really changed since then. I'm not finding any material in the Delphi Help file, and searches have not returned very much. I did find the Accidental Programmer's page on the Open Tools, but that looks like it was last up dated in 1998? It does at least have the correct unit names and uses the new interfaces. I'm willing to track down and buy an older book if that is the best reference.

  • How can I write faster JavaScript?

    - by a paid nerd
    I'm writing an HTML5 canvas visualization. According to the Chrome Developer Tools profiler, 90% of the work is being done in (program), which I assume is the V8 interpreter at work calling functions and switching contexts and whatnot. Other than logic optimizations (e.g., only redrawing parts of the visualization that have changed), what can I do to optimize the CPU usage of my JavaScript? I'm willing to sacrifice some amount of readability and extensibility for performance. Is there a big list I'm missing because my Google skills suck? I have some ideas but I'm not sure if they're worth it: Limit function calls When possible, use arrays instead of objects and properties Use variables for math operation results as much as possible Cache common math operations such as Math.PI / 180 Use sin and cos approximation functions instead of Math.sin() and Math.cos() Reuse objects when passing around data instead of creating new ones Replace Math.abs() with ~~ Study jsperf.com until my eyes bleed Use a preprocessor on my JavaScript to do some of the above operations

  • What are the difference between Cygwin on windows and real UNIX environment

    - by Tarun
    Hi, I am a C/C++ developer. I have never done C++ programming on UNIX, I have done only on windows. I want to practice C++ on Unix. (Because all big companies ask C++ with Unix). I have a laptop on which i do not want to install any other OS (because i have installed very important software on it and i don't have setups) So, I searched and found CygWin which is Unix emulator for Windows. I am thinking to practice C++ on this. Please help me, how can I practice/learn in more close to the environment(Unix Environment) that is used in Big companies like IBM. What will be the difference between Unix and Cygwin?

  • Is there an off the shelf CMS that can be used as a back end for smartphone travel guide apps?

    - by eamonncarey
    I'm wondering if there's an off the shelf CMS available that is similar to something like Mobile Roadie - ie: it will allow you to create multiple versions of one application? I'm looking to develop some mobile travel guides for iPhone/Android/Blackberry etc, and rather than get a CMS built, I'd like to see if there's something out there is similar to Wordpress in that it will allow us to input text, images, Google Maps details, phone numbers, email addresses and potentially some audio/video content. If anyone knows of anything, I'd love to hear about it. Also, if you have any ideas regarding pricing, that would be extremely helpful! Thanks in advance for your assistance.

  • SVN user guidelines

    - by Oliver Moran
    I have been tasked with writing a set of user guidelines for SVN for developers in my company. The guidelines are to be solely from a user perspective (e.g. commit comments, when to commit) and not from an administrative perspective (e.g. when to tag, how to structure). An administrative guideline will be written in a separate document. We are an app development house involved also in embedded development. So our developers range from HTML5 and Flash to Java and C. Some of our coding involves forking very large (millions of files) code bases. Other parts involve us engaging in ground-up development. Are there any best practices for use of SVN from a user (i.e. grunt developer) perspective?

  • C# connectionString encryption questions

    - by 5YrsLaterDBA
    I am learning how to encrypt the ConnectionString for our C# (3.5) Application. I read the .Net Framwork Developer Guide (http://msdn.microsoft.com/en-us/library/89211k9b(VS.80).aspx) about securing connection string. but not fully understand the contents. It says "The connection string can only be decrypted on the computer on which it was encrypted." We have a release machine which will build our application which will generate the OurApp.exe.config and then install it to many product machines. Is that meam we have to have this encryption process separated with our application and run it at individual product machine? We may use the "RSAProtectedConfigurationProvider". It mentioned we need encryption key for that provider. when and how we should provide the encryption key? thanks,

  • Commiting broken code to the repository for the purpose of backing it up

    - by Tim Merrifield
    I was just talking to another developer (more senior than I) and trying to convince him that we should implement continuous integration via Cruise Control. He told me that this will not work because he commits code that does not compile to the repository all the time for the purposes of backing it up. And that automated builds notifying us of failures would be just noise. Committing garbage to the repo sounds bad to me. But I was at a loss of words and didn't know what to say. What is the alternative? What's the best practice for backing up your code on another machine without adding a bunch of pointless revisions? BTW, our version control system is SVN and that probably won't change any time soon.

  • Getting a senior job without the yrs of experience asked for

    - by dotnetdev
    Hi, My manager in my current company feels that I am selling myself short by getting another job - but as a senior. He feels I have sold myself short and missing out on a good salary by getting another junior job, given how he (my manager) has a lot of faith in my development skills. However, I have not worked long enough for a proper senior job (5 years +) but then the senior developer we do have in my current company isn't given senior tasks (judged by difficulty). How would I get a senior job if I lack the commercial experience? My manager still feels without that, I have the ability/knowledge (I help my manager with C# too). Thanks

  • Creating a Pop up and setting its view state before it displays

    - by theringostarrs
    Hi, I am a beginner developer in Flex, and I have been using viewstates lately. I had a couple of custom popup titlewindow components that are initialized using: PopUpManager.createPopUp(this, ContentCreate, true); They both contain view states already, and are very similar so I wanted to combione them into one popup titlewindow and change view state on initialisation of the popup to either the Create version of the popup or the Update. I thought I was being smart haha, but I realized soon after refactoring my code that, I as far as I know I can't pass parameters to the popup to indicate which state I want, if it is created using the PopUpManager. Does anyone know how to pass parameters to the PopupManager, or create the ContentCreate component(TitleWindow) in mxml or code so I can specify the view state?

  • How to setup a http(s) proxy with record/replay functionality?

    - by superb
    The use case is: I want to do some android app performance tests and I want to fix the data when app got from web. The solution I come up with is to setup a local http proxy, which can first record all http traffic, and later replay then app is running perf tests. I found http://mitmproxy.org/, which has exactly the features I want. but seems with the default settings it cannot be used as a https proxy. I tried using it as proxy and login to facebook but doesn't work. I am not familiar with the https protocol and how cert things work. Any one can provide some help? Thanks a lot.

  • What is tha CAUSE of Error 523 and Error 200 in Blackberry handhelds

    - by voipsecuritydigest.com
    I'm Blackberry developer, customers using my application experiencing Error 523 and Error 200. Remedies to those errors are in first case - remove application, my application. In second case totally reload OS! This is very bad, and customers blame me! But this is I don't do anything illegal to make blackberry crash. I just used a lot of memory, which is obvious because customer want that. Everywhere including Blackberry knowledge base people talking how to fix the problem, which may happened to everybody using application from well known brands, for example Yahoo! finances. But nobody explains what is the mechanism behind this, and if it is possible to avoid the problem. I would like to know what is that CAUSE of Error 523 and Error 200?

  • Python: How to quit CLI when stuck in blocking raw_input?

    - by christianschluchter
    I have a GUI program which should also be controllable via CLI (for monitoring). The CLI is implemented in a while loop using raw_input. If I quit the program via a GUI close button, it hangs in raw_input and does not quit until it gets an input. How can I immediately abort raw_input without entering an input? I run it on WinXP but I want it to be platform independent, it should also work within Eclipse since it is a developer tool. Python version is 2.6. I searched stackoverflow for hours and I know there are many answers to that topic, but is there really no platform independent solution to have a non-blocking CLI reader? If not, what would be the best way to overcome this problem? Thanks

  • Python as your main language. Possible?

    - by Deinumite
    I am currently attending college and the languages that I will 'know' by graduation are C++ and Java. That being said, i am also in the process of teaching myself Python. I know that every programming language has its own pros and cons, but would it be possible to become a python developer out of school? I always have more 'fun' programming in Python than i do in C++ or Java, and I am also in love with Pythons documentation. I know C++ will always be on top in terms of speed, but what would be the benefit of memorizing every javadoc against focusing on Python instead? are there good jobs to be had with Python? edit: also, would it be beneficial for me to look at C# as well? Microsoft is really throwing their support at it so that could be a decent career path as well.

  • WPF Books in 2010

    - by notJim
    I'm looking to learn WPF, and I'd like to get a book to help in the process. Most of the popular questions on SO regarding actual books are from 2008, and I wanted to see if recommendations for books had changed at all. WPF Unleashed, which seems to be the most popular recommendation, was published in 2006, which is quite a while ago, with the lightening-quick pace that Microsoft has been following with .NET. Does this book still work? For some background, I'm a web developer (using MVC, so MVVM makes sense to me conceptually), looking to make the jump to desktop development. I did C# a while ago, but I'll be picking up a separate C# book to get up to speed on that. I am not interested in Silverlight. I am not necessarily interested in flashy UIs right now, as I'm working on business software but what I am interested in is good, clean, intuitive user interfaces.

  • How does transmission created it's cross plataform app? It has from Qt/Mac to CLI interfaces!

    - by Somebody still uses you MS-DOS
    I'm amazed at Transmission, a BT client. It has a Mac, a GTK+, a QT, a Web Client and a CLI interface to it. I tried reading some of it's source to understand how he creates all these interfaces, but no luck. Does the developer creates them using a single ide? Or does he create the interface logic in each specific environment (specially mac), "exports" this window code and integrates with the main logic? How did the developers create this software with so many interfaces?

  • Are there viable alternatives for Web 2.0 apps besides lots of Javascript?

    - by djembe
    If you say find C-style syntax to be in the axis of evil are you just hopelessly condemned to suck it up and deal with it if you want to provide your users with cool web 2.0 applications - for example stuff that's generally done using JQuery and Ajax etc? Are there no other choices out there? We're currently building intranet apps using pylons and a bunch of JavaScript along with a bit of Evoque. So obviously for us the world would be a better place if instead something equivalent existed written in like PythonScript. But I've yet to seen anything approaching that aside from the Android system's ASE - but obviously that's something rather unrelated. Still - if browsers could support other scripting languages....

  • How do you add < or > to a summary tag in Visual studio?

    - by Tony
    How do you add < (less than) or (greater than) to a summary comment in visual studio? I am in Visual Studio 2008. I have a generic method: public bool IsMemberProtected<T>(Expression<Func<T, object>> expression) Would love to have a summary tag of something like this /// <summary> /// Determines whether a member is protected. /// /// Usage: IsMemberProtected<ExampleType>(x => x.Member) /// </summary> But when I do that, the tooltip for the property no longer works when a developer hovers over the method in code to view the summary tag. Thoughts?
