• Can a loosely typed language be considered true object oriented?

  - by user61852

  Can a loosely typed programming language like PHP be really considered object oriented? I mean, the methods don't have returning types and method parameters has no declared type either. Doesn't class design require methods to have a return type? Don't methods signatures have specifically-typed parameters? How can OOP techniques help you code in PHP if you always have to check the types of parameters received because the language doesn't enforce types? Please, if I'm wrong, explain it to me. When you design things using UML, then code classes in PHP with no return-typed methods and no-type parameters... Is the code really compliant with the UML design? You spend time designing the architecture of your software, then the compiler doesn't force the programmer to follow your design while coding, letting he/she assign any object variable to any other variable with no "type-mismatch" warning.

• How to document/verify consistent layering?

  - by Morten

  I have recently moved to the dark side: I am now a CUSTOMER of software development -- mainly websites. With this new role comes new concerns. As a programmer i know how solid an application becomes when it is properly layered, and I want to use this knowledge in my new job. I don't want business logic in my presentation layer, and certainly not presentation stuff in my data layer. Thus, I want to be able to demand from my supllier that they document the level of layering, and how neat and consistent the layering is. The big question is: How is the level of layering documented to me as a customer, and is that a reasonable demmand for me to have, so I don't have to look in the code (I'm not supposed to do that anymore)?

• Why is design by contract considered an alternative to the pseudo programming process?

  - by zoopp

  Right now I'm reading Code Complete by Steve McConnell and in chapter 9 he talks about the Pseudo Programming Process (PPP). From what I've understood, the PPP is a way of programming in which the programmer first writes the pseudo code for the routine he's working on, then refines it up to the point where pretty much each pseudo code line can be implemented in 1-3 lines of code, then writes the code in the designated programming language and finally the pseudo code is saved as comments for the purpose of documenting the routine. In chapter 9.4 the author mentions alternatives to the PPP, one of which is 'design by contract'. In design by contract you basically assert preconditions and postconditions of each routine. Now why would that be considered an alternative? To me it seems obvious that I should use both techniques at the same time and not chose one over the other.

• Testing on Device Other Than the Known Brand Question (Local and Imported Phone Question)

  - by David Dimalanta

  I have a question. When testing a device by using Eclipse, it's easy to install and add device software with these specific brands commonly used in game testing like Samsung, Google, T-Mobile, and HTC; according to the Android Developers website. What if I'm using other brands that runs on Android to test the program via Eclipse (i.e. MyPhone, Starmobile), what should I look for to download in order to enable testing phones that those brands are using other than the brands that are known and commonly used: model number or simply brand? Here's some examples of these brands other than the brands we've known that runs on Android: Starmobile Engage 7 (http://www.lazada.com.ph/Starmobile-Engage-7-Android-40-4GB-with-Wi-Fi-Black-Starmobile-Mercury-B201-COMBO-39833.html/) My|Phone A898 Duo (http://www.myphone.com.ph/#!a898-duo/c1yt) Also, take note that I'm a Filipino programmer working at the Philippines to test our local smartphones for the created Android game or app. Hope you can understand me for my help.

• Better Programming By Programming Better?

  - by ahmed

  I am not convinced by the idea that developers are either born with it or they are not. Where’s the empirical evidence to support these types of claims? Can a programmer move from say the 50th to 90th percentile? However, most developers are not in the 99th or even 90th percentile (by definition), and thus still have room for improvement in programming ability, along with the important skills.The belief in innate talent is “lacking in hard evidence to substantiate it” as well.So how do I reconcile these seemingly contradictory statements? I think the lesson for software developers who wish to keep on top of their game and become experts is to keep exercising the mind via effortful studying. I read a lot technical books, but many of them aren’t making me better as a developer.

• Are there examples of non CRUD approaches?

  - by Pieter B

  I'm a programmer but also have worked as an archivist. As archivist it's a lot about keeping data. I often get into arguments with colleagues when it comes to operations on data. I don't like the U and the D in CRUD too much. Rather then update a record I prefer to add a new one and have a reference to the old record. That way you build a history of changes. I also don't like deleting records but rather mark them as inactive. Is there a term for this? Basically only creating and reading data? Are there examples of this approach?

• Looking for an open source project in Python

  - by Roman Yankovsky

  I am looking for practical tasks to get experience with Python. Just reading the books and not doing any tasks in the language is not effective. I solved some problems on the Project Euler and TopCoder and it helped me to learn the syntax of the language better. But those tasks are hard algorithmically, but as a rule is quite simple from the point of view of programming. Now I'm looking for an interesting open source project in Python, participation in which will help me to better understand the OO-model of language. Although, this is my first step with Python, in general, I am an experienced programmer and I can be useful for a project. May be someone can suggest something?

• Does the use of debuggers have an effect on the efficiency of programmers? [closed]

  - by alain.janinm

  Possible Duplicate: Are debugging skills important to become a good programmer? I'm a young Java developer and I make a systematic use of the Netbeans debugger. In fact, I often develop my applications when I debug step by step in order to see immediately if my code works. I feel spending a lot of time programming this way because the use of debugger increase execution time and I often wait for my app to jump from a breakpoint to an other (so much that I've the time to ask this question). I never learned to use a debugger at school, but at work I've been told immediately to use this functionality. I started teaching myself to use it two years ago, and I've never been told any key tips about it. I'd like to know if there are some rules to follow in order to use the debugger efficiently. I'm also wondering if using the debugger is eventually a good practice? Or is it a loss of time and I've to stop now this bad habit?

• Methods to Manage/Document "one-off" Reports

  - by Jason Holland

  I'm a programmer that also does database stuff and I get a lot of so-called one-time report requests and recurring report requests. I work at a company that has a SQL Server database that we integrate third-party data with and we also have some third-party vendors that we have to use their proprietary reporting system to extract data in flat file format from that we don't integrate into SQL Server for security reasons. To generate many of these reports I have to query data from various systems, write small scripts to combine data from the separate systems, cry, pull my hair, curse the last guy's name that made the report before me, etc. My question is, what are some good methods for documenting the steps taken to generate these reports so the next poor soul that has to do them won't curse my name? As of now I just have a folder with subfolders per project with the selects and scripts that generated the last report but that seems like a "poor man's" solution. :)

• expand window to free space on screen in kde

  - by Pascal Rosin

  I am using Kubuntu and I want to expand the current window to the free space on the screen or to say it more precisely: I want to make the current window as big as possible without overlapping new windows (windows already overlapped should be ignored). Is there a keyboard shortcut or an extension to the KDE Window management, that realizes such a shortcut or a window button? I would also appreciate a hint, how to write a script that could do this window thing on keyboard shortcut invocation. I am a programmer but don't know what the best way is to control KDE Windows via script.

• How do people deal with Android fragmentation?

  - by Bill

  I've spent the past few years working on iOS apps, and I'm now giving some serious consideration to creating an Android port of one of my apps. I'm sure that complaints about fragmentation are a frustrating cliche to experienced Android programmers, but as an iOS programmer, I'm quite honestly overwhelmed by the number of configurations and devices that my app might end up running on. There are literally thousands of Android devices in the wild, but I know there are successful Android developers in the world and I know they're not testing or developing for thousands of different devices. So how can a relatively small company deal with fragmentation? Is it possible to pick the five or six most popular devices, focus on those and prevent the app from being installed on any other devices? Are there any other strategies for practically dealing with the number of different configurations an app will face?

• How does one improve one's problem-solving ability?

  - by gcc

  How can one improve one's problem-solving ability? Everyone says same thing: "a real programmer knows how to handle real problem." But they forget how they learn this ability, or where (I know in school, no one gives us any ability, of course in my opinion). If you have any idea except above ones, feel free when you give your advice solve more problems do more exercises, write code, search google then write more ... For me, my question is like "use complex/known library instead of using your own." In other words, I want your personal experience, book recommendation, webpage on problem solving. Moreover, look your problem-solving method and give us your personal ability as if it is an algorithm

• Linux Books For Windows/C++ Programmers?

  - by John Dibling

  I'm a Windows C++ programmer with a great deal of experience, and I'm looking for book recommendations to get up to speed with programming in Linux (specifically RHE 6). Ideally, I'd like a book geared specifically to my needs. Something along the lines of "Linux C++ Programming for Windows Experts" would be nice. :) I'm open to any recommendations you have. My domain is primarily financial market data servers (no GUIs) and simple console apps. I do a lot of multithreading, a lot of networking, not a lot of user interface stuff. I know C++0x, but our production codebase can only use C++. Thanks for your recommendations for books and/or resources!

• Beginners Tips To Learn Vim

  - by Nathan Campos

  I'm the type of developer that only uses GUI fully-featured programmer editor, when I'm at Windows I use Notepad++, at my Mac I use TextMate and at Linux I use GEdit, but now I'm starting to develop inside my Linux server, which doesn't have any window manager installed and I saw this as a beautiful time to learn how to use Vim, which I always had problems to understand, I can't even open a file to edit at Vim, so I want to know: Which is the best eBook for a very beginner on this editor to learn how to use it? I really loved Vim after I saw all the awesome things that you can do with it and this is the perfect moment to learn how to use it. PS: It would be a lot better if it has a Kindle or ePub version

• Should Swing knowledge be required from Java programmers?

  - by Anto

  Swing is an integral part of the Java API. It is also the most popular GUI framework for Java. I still wonder, should every Java programmer still know, or at least be pretty familiar with, Swing (possibly excluding web developers)? There are alternatives (e.g. SWT), but they are not very widely used (compared to Swing). What do you think about requiring Swing knowledge from Java programmers? If such knowledge is important, to what degree? Are the basics enough or not? The reason I wonder is because I really don't like Swing but wonder if I still should brush up my skills in it. I'm able to create simple GUIs in it, but I would definitely not say that I know Swing well.

• what is best book to learn optimized programming in java [closed]

  - by Abhishek Simon

  Possible Duplicate: Is there a canonical book for learning Java as an experienced developer? Let me elaborate a little: I used to be a C/C++ programmer where I used data structure concept like trees, queues stack etc and tried to optimize as much as possible, minimum no. of loops, variables and tried to make it efficient. It's been a couple of years that I started writing java codes, but it is simply not that efficient in terms of performance, memory intensive etc. To the point: I want to enter programming challenges using java so I need to improve my approach at things I program. So please suggest me some books that can help me learn to program better and have a chance in solving challenges in programming.

• Website development from scratch v/s web framework [duplicate]

  - by Ali

  This question already has an answer here: What should every programmer know about web development? 1 answer Do people develop websites from scratch when there are no particular requirements or they just pick up an existing web framework like Drupal, Joomla, WordPress, etc. The requirements are almost similar in most cases; if personal, it will be a blog or image gallery; if corporate, it will be information pages that can be updated dynamically along with news section. And similarly, there are other requirements which can be fulfilled by WordPress, Joomla or Drupal. So, Is it advisable to develop a website from scratch and why ? Update: to explain more as got commentt from @Raynos (thanks for comment and helping me clearify the question), the question is about: Should web sites be developed and designed fully from scratch? Should they be done by using framework like Spring, Zend, CakePHP? Should they be done using CMS like Joomla, WordPress, Drupal (people in east are using these as frameworks)?

• My Latest Hare-Brained Scheme

  - by Liam McLennan

  I have not had a significant side project for a while but I have been working on a product idea. Its an analytics application that analyses twitter data and reports on market sentiment. The target market is companies who want to track trends in consumer sentiment. My idea is to teach the application to divide relevant tweets into ‘positive’ and ‘negative’ categories. If the input was the set of tweets featuring the word ‘telstra’ the application would find the following tweet:   and put it in the ‘negative’ category. Collecting data in this fashion facilitates the creation of graphs such as: which can then be correlated against events, such as a share offer or new product release. I may go ahead and build this, just because I am a programmer and it amuses me to do so. My concerns are: There  is no market for this tool There is a market, but I don’t understand it and have no way to reach it.

• Is it worth being computer languages polyglot?

  - by Anton Barkowski

  You can often hear that programmers should learn many different languages to improve themselves. I still go to school and don't have big programming experience (a little more than year). But what was noble intention to improve programming skills turned into some kind of OCD: I feel that I won't calm down until I learn all relatively known programming languages. And here is question itself: Will being programming languages polyglot actually help you (And I don't mean usual "Programmer should know at least all paradigms", I mean really all languages you usually hear about)? Does anybody have similar experience? Does it help with job/skills/career? How often are you able to apply those skills?

• creating a google wave clone using php/mysql/jquery

  - by jeansymolanza

  seasons greetings to all. i have a question that has been rather bugging me as of late. does anyone know how one can create a google wave clone using php/mysql/jquery as primary points of development. any ideas on how this might be possible and recommend any starting points? i have some time off work and it would be an interesting project to undertake as i want to use it in an e-learning framework next year. i will be testing the product on a XAMPP local server. i understand some of the technologies that google wave using but i am rather curious as to how these can be developed to a decent standard using php/mysql/jquery (i mention these three because i am quite adept at them). any links to resources best suited to an intermediate programmer would be appreciated. many thanks and God bless. so far i have this: http://konrness.com/javascript/google-wave-style-scroll-bar-jquery-plugin/

• Best keyboard drawer for programmers?

  - by David Pfeffer

  I'm a programmer with pretty severe neck problems. I program with three monitors, and I've found that my desk's short depth causes me to have to rotate my neck too much to see the "wing" screens. I can't get a deeper desk due to space restrictions. I'm looking for a keyboard drawer that can be installed onto a desk. However, I like the height of the keyboard on the desk. I'd like a drawer that is extremely low-profile/slim. My keyboard is less than 1" tall, so it'll fit pretty much anywhere. My ideal product would slide out from under my desk and "pop up" so that its surface is even with the desk. Does anything slim and nice like this exist? I'll even consider replacing the desk if a desk exists with this built-in.

• Is it possible to create and distribute an app for the BlackBerry Playbook that doesn't go into App World?

  - by Drackir

  My company is looking to create an app that we'll use internally on several (about 20) BlackBerry Playbooks. We don't want it to be put up on App World because it's just an internal application. I'm wondering if there are any: Costs involved with this outside of paying a programmer to develop it - i.e. Are there any license fees, deployment fees, etc. License issues involved with deploying the app to multiple Playbooks without deploying it to App World Limitations on functionality of the app Other things we should be taking into consideration If it matters, the app will be collecting information and downloading it to a computer via USB.

• Is the C programming language still used?

  - by Pankaj Upadhyay

  I am a C# programmer, and most of my development is for websites along with a few Windows application. As far as C goes, I haven't used it in a long time, as there was no need to. It came to me as a surprise when one of my friends said that she needs to learn C for testing jobs, while I was helping her learn C#. I figured that someone would only learn C for testing only if there is development done in C. In my knowledge, all the development related to COM and hardware design are also done in C++. Therefore, learning C doesn't make sense if you need to use C++. I also don't believe in historic significance, so why waste time and money in learning C? Is C is still used in any kind of new software development or anything else?
