• Understanding the Java Ecosystem

  - by syrion

  I have traditionally had the "luxury" of being a one-man development team. I've used Python extensively, have a reasonable command of Perl, PHP, and JavaScript. My problem is Java. I can write Java code. I'm not great at it--unlike Python, I rarely make use of anything unique to Java when I'm writing it. Furthermore, my experience is mostly in simple GUI/console programming. Unfortunately, I'm currently pursuing an IT degree where Java is the lingua franca. My database class is requiring that our projects be written in Java using servlets, and I just can't wrap my head around the ecosystem. Is there a good online overview of or tutorial on how the Java web ecosystem works? I have Thinking in Java, but it's mostly just the language itself (which I understand well enough to get by). I have looked at the Sun servlet tutorial, but it seems outdated.

• Why is implementing copy-paste in a touch screen based smartphone such a big deal?

  - by EpsilonVector

  I'm not entirely sure this is on-topic, but it definitely needs a programmer's understanding to be answered, and deals with general development (for a specific scenario) as opposed to a specific piece of code. In a way it also translates into "what are the challenges in doing X in a touch screen app", and similar questions have been asked here in the past. So here it is: When Apple didn't implement copy-pasting on the iPhone since version 1 I just assumed it was a UI issue- they were waiting until they figured out a good UI for it. But now the idea is out there, and Microsoft still released Windows Phone 7 without copy-pasting, promising it'll be ready in a few months. My question is: why does this takes a few months to implement? Are there some technological challenges that are unique to programming for a touch screen that I'm not familiar with?

• Training a 'replacement', how to enforce standards?

  - by Mohgeroth

  Not sure that this is the right stack exchange site to ask this of, but here goes... Scope I work for a small company that employs a few hundred people. The development team for the company is small and works out of visual foxpro. A specific department in the company hired me in as a 'lone gunman' to fix and enhance a pre-existing invoicing system. I've successfully taken an Access application that suffered from a lot of risks and limitations and converted it into a C# application driven off of a SQL server backend. I have recently obtained my undergraduate and am no expert by any means. To help make up for that I've felt that earning microsoft certifications will force me to understand more about .net and how it functions. So, after giving my notice with 9 months in advance, 3 months ago a replacement finally showed up. Their role is to learn what I have been designing to an attempt to support the applications designed in C#. The Replacement Fresh out of college with no real-world work experience, the first instinct for anything involving data was and still is listboxes... any time data is mentioned the list box is the control of choice for the replacement. This has gotten to the point, no matter how many times I discuss other controls, where I've seen 5 listboxes on a single form. Classroom experience was almost all C++ console development. So, an example of where I have concern is in a winforms application: Users need to key Reasons into a table to select from later. Given that I know that a strongly typed data set exists, I can just drag the data source from the toolbox and it would create all of this for me. I realize this is a simple example but using databinding is the key. For the past few months now we have been talking about the strongly typed dataset, how to use it and where it interacts with other controls. Data sets, how they work in relation to binding sources, adapters and data grid views. After handing this project off I expected questions about how to implement these since for me this is the way to do it. What happened next simply floors me: An instance of an adapter from the strongly typed dataset was created in the activate event of the form, a table was created and filled with data. Then, a loop was made to manually add rows to a listbox from this table. Finally, a variable was kept to do lookups to figure out what ID the record was for updates if required. How do they modify records you ask? That was my first question too. You won't believe how simple it is, all you do it double click and they type into a pop-up prompt the new value to change it to. As a data entry operator, all the modal popups would drive me absolutely insane. The final solution exceeds 100 lines of code that must be maintained. So my concern is that none of this is sinking in... the department is only allowed 20 hours a week of their time. Up until last week, we've only been given 4-5 hours a week if I'm lucky. The past week or so, I've been lucky to get 10. Question WHAT DO I DO?! I have 4 weeks left until I leave and they fully 'support' this application. I love this job and the opportunity it has given me but it's time for me to spread my wings and find something new. I am in no way, shape or form convinced that they are ready to take over. I do feel that the replacement has the technical ability to 'figure it out' but instead of learning they just write code to do all of this stuff manually. If the replacement wants to code differently in the end, as long as it works I'm fine with that as horrifiying at it looks. However to support what I have designed they MUST to understand how it works and how I have used controls and the framework to make 'magic' happen. This project has about 40 forms, a database with over 30 some odd tables, triggers and stored procedures. It relates labor to invoices to contracts to projections... it's not as simple as it was three years ago when I began this project and the department is now in a position where they cannot survive without it. How in the world can I accomplish any of the following?: Enforce standards or understanding in constent design when the department manager keeps telling them they can do it however they want to Find a way to engage the replacement in active learning of the framework and system design that support must be given for Gracefully inform sr. management that 5-9 hours a week is simply not enough time to learn about the department, pre-existing processes, applications that need to be supported AND determine where potential enhancements to the system go... Yes I know this is a wall of text, thanks for reading through me but I simply don't know what I should be doing. For me, this job is a monster of a reference and things would look extremely bad if I left and things fell apart. How do I handle this?

• How do I know when should I package my classes in Ruby?

  - by Omega

  In Ruby, I'm creating a small game development framework. Just some personal project - a very small group of friends helping. Now I am in need of handling geometric concepts. Rectangles, Circles, Polygons, Vectors, Lines, etc. So I made a class for each of these. I'm stuck deciding whether I should package such classes in a module, such as Geometry. So I'd access them like Geometry::Rectangle, or just Rectangle if I include the module. Now then, my question isn't about this specific scenario. I'd like to know, when is it suitable to package similar classes into one module in Ruby? What factors should I consider? Amount of classes? Usage frequency? Complexity?

• Problems connecting to eduroam wifi - ubuntu touch

  - by Fiona Cox

  I am trying to connect to our university's eduroam wi-fi network with my Nexus 4 running Ubuntu touch (utopic latest build), but can't get past the first stage. I wonder if anyone can help please? I am following these instructions (which worked for my iPhone): http://www.st-andrews.ac.uk/itsupport/mobile/eduroam/ But when I go to the bandit.st-andrews.ac.uk/connect page then follow the link to 'eduroam setup' I get the error message: Authorization Required This server could not verify that you are authorised to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required. Apache/2.2.16 (Debian) Server at bandit.st-andrews.ac.uk Port 443 (Clearly it's the latter option (browser) as I haven't been asked for my credentials yet.) Is there a way round this, or am I just not going to be able to connect until further down the Ubuntu touch development road... Thanks!

• Do you develop with localization in mind?

  - by Jimmy C

  When working on a software project or a website, do you develop with localization in mind? By this I mean e.g. Externalizing all strings, including error messages. Not using images that contain text. Designing your UI with text expansion in mind. Using pseudo-translation to test your UI's early in the process. etc. On projects you work on, are these in the 'nice to have' category and let the L10N team worry about the rest, or do you have localization readiness built into your development process? I'm interested to hear how developers view localization in general.

• Dynamic URL of asp.net web service with web reference

  - by Jalpesh P. Vadgama

  It’s been a while I am writing this. But never late.. So I am writing this. Before some time one of friend asked about the URL of web service when we add reference. So I am writing this. Some of you may find this very basic but still many of people does not know this that’s why I am writing this. In today’s world we have so many servers like development, preproduction and production etc. and for all the server location or URL of web service will be different.But with asp.net when you add a web reference to your web application it’s create a web reference settings in web.config where you can change this path. So it’s very easy to just change that path and you don’t have to add web reference again. Read More

• Validating User Stories: How much change is too much?

  - by David Kaczynski

  While the core of requirements development and acceptance criteria would ideally take place during the planning meeting in order to create a better estimate, Scrum encourages continuous interaction with the product owner throughout the sprint to validate and refine user stories. What kind of criteria is used to judge if there is too much change being imposed on a user story mid-sprint? When is it appropriate to change the requirements of the user story? When is it appropriate to cancel the user story / sprint in order to re-evaluate and re-estimate a user story in question?

• Good Literature for "Object oriented programming in C"

  - by Dipan Mehta

  This is not a debate question about whether or not C is a good candidate for Object oriented programming or not. Quite often C is the primary platform where the development is happening. I have seen, and hopefully learnt through crawling many open source and commercial projects - that while the language inherently doesn't stop you if you create "non-object" code. However, you can still think in the "Object" way and reasonably write code that captures this designs thinking. For those who has done this, OO way is still the best way to write code even when you are programming in C. While, I have learnt most of it through the hard way, are there any deep literature that can help educate the relatively young guys about how to do OO programming in C?

  It's hot-hot-hot! The market for Java and mobile developers keeps growing hotter, and hotter--so says the latest Dice survey. See: Dice survey says Java & Mobile are tops Here's a quote: The market for mobile developers is expanding faster than the talent pool can adapt, a Dice survey indicates. Software developers in general—as well as Java, mobile software and Microsoft .Net developers in particular—are in short supply today. Those fields represent four of the top five most difficult positions IT managers are looking to fill... ... The New York/New Jersey metro area led the country with 8,871 positions listed... So, if you are looking to get into software development get crackin' in learning Java mobile programming and move to NY or NJ. Let's go Mets! Hinkmond

• The clean coders videos [closed]

  - by Sebastian

  As many others, I have been reading Uncle Bob Martins books. More specifically, clean code and then "the clean coder". Now, over the last year he has been producing "code casts" that you can buy for ~20USD a piece. I bought the first episode sometime in mid 2011 and wasnt that impressed, as I really learned nothing new after reading his books. Last night I bought the first episode of test driven development with more or less the same result as last time. Now tonight I gave it one more go and bought TDD part 2 and this one was, IMO, really good. With this post I would like to tip others about his videos and would also like to know what others think.

• Question about Web Programming certificate program

  - by user134226

  I am currently attending St. John's University with a major of Computer Science. I am entering my senior year next year and stumbled upon this certificate program for web development from Hunter College: http://www.hunter.cuny.edu/ce/certificates/computer/web-programming So the question is, would it be beneficial for me to complete this program or to just attend a few elective courses in the summer at a school such as NYU? Would this certificate be good for my resume? The only language I have learned so far is Java and classes I have taken in the field so far are: Programming Fundamentals 1 and 2, Data Security and Cryptography, Networking: Data Communications and Introduction to Data Structures Hope some of you can help me out, thanks

• Examples and Best Practices for Seeding Defects?

  - by MathAttack

  Defect Seeding seems to be one of the few ways a development organization can tell how thorough an independent testing group is. I'm a fan of using metrics to help counter overconfidence biases, and drive discussions around facts. With that said, I haven't seen Seeding Defects used in practice. Are there best practices above and beyond what McConnell explained? Are there public examples where this has been done? In the absence of the above, any thoughts on why it hasn't been done more? Thanks in advance!

• Is there a difference between "self-plagiarizing" in programming vs doing so as a writer?

  - by makerofthings7

  I read this Gawker article about how a writer reused some of his older material for new assignments for different magazines. Is there any similar ethical (societal?) dilemma when doing the same thing in the realm of Programming? Does reusing a shared library you've accumulated over the years amount to self-plagarizm? What I'm getting at is that it seems that the creative world of software development isn't as stringent regarding self-plagarism as say journalism or blogging. In fact on one of my interviews at GS I was asked what kind of libraries I've developed over the years, implying that me getting the job would entail co-licensing helpful portions of code to that company. Are there any cases where although it's legal to self-plagarize, it would be frowned upon in the software world?

• How can I refactor client side functionality to create a product line-like generic design?

  - by Nupul

  Assume the following situation similar to that of Stack Overflow: I have a system with a front-end that can perform various manipulations on the data (by sending messages to REST back-end): Posting Editing and deleting Adding labels and tags Now in the first version we created it well modularized but the need as of now for 'evolving' the system similar to Stack Overflow. My question is how best to separate the commonality and how to incorporate the variability with respect to the following: Commonality: The above 'functionalities' and sending/receiving the data from the server Look and feel (also a variability as explained below) HTTP verbs associated with the above actions Variability: The RESTful URLs where the requests are sent The text/style of the UI (the commonality is analogous to Stack Overflow - the functionality of upvotes, posting a question remains the same, but the words, the icons, the look and feel is still different across sites) I think this is entirely a client-side code organization/refactoring issue. I'm heavily using jQuery, javascript and backbone for front-end development. My question is how best should I isolate the same to be able to create multiple such aspects to the tool we are currently working on?

• How important is using the same language for client and server?

  - by Makita

  I have been evaluating architecture solutions for a mobile project that will have a web-service/app in addition to native apps and have been looking at various libraries, frameworks, and stacks like Meteor, this being a sort of "open stack package framework", is tightly bound with Node.js. There is a lot of talk about the benefits of using the same language both client and server side, and I'm not getting it. I could understand if you want to mirror the entire state of a web application on both client and server but struggling to find other wins... Workflow efficiency? I'm trying to understand why client/server language parity is considered to be a holy grail. Why does client/server language parity matter in software development?

• Ubuntu user credentials, file permissions

  - by user9843

  I am using Ubuntu 10.10 for web development by using the symfony framework. Normally I install Ubuntu Lamp (Turnkey edition), log in as root and configure all the necessary software in the server needed to work with symfony. (Samba, symfony etc) The problem is when I am root the file permissions are not set right for the Samba and symfony systems. All things I do/create in the terminal (CLI) of Ubuntu create file permissions for the user root. Off course I know how to change them afterwards but that takes up time I could spend programming. When ready I am using the box via my network, creating several site directorys directly from my pc on the server. There are multiple sites on this developer server as directorys under /var/www/ there are no virtual hosts. My question is how to create or set a user after installation of Ubuntu with the right credentials and rights?

• Learning PHP OOP

  I have been coding PHP for about 2 years now and I THINK that I have a very good grasps of the fundamental parts of PHP, i.e. Functions foreach/IF statements sessions/cookies POST/GET Amongst a few others. I want to move on to learning OOP PHP now, so learning how to use classes and making it a really valuable skill. I have 1 requirement, the source must be a respected source that doesn't teach developers bad habits. I have the book: PHP and MySQL Web Development However, as useful as that is I would like an online source. I would like to know from people with experience in OOP PHP, how and where did they learn OOP PHP. Obviously by doing, but I would really appreciate some great resources which help me along the way.
