• Collaboration between client, web designer, and web developer

  - by Alex

  I am primarily a Web Developer (back end programming) - but intend to offer a complete service to my clients, from concept, to brand design, photoshop mock-ups and everything else in between. I'm aware that it's a good idea to outsource this design aspect of the project to someone that I trust. My question is more about the process: I imagine that in order for the designer to really grasp what the client wants to create, they would need some sort of interaction. Therefore, does anyone know if it is common to bring both parties into a 3 way discussion? Or is it more common to get all of the info from the client, and then pass it onto the designer, and act as a back and forth middleman? Afterall, I am the designer's client. Any insight into this would be great

• Publish/Subscribe/Request for exchange of big, complex, and confidential data?

  - by Morten

  I am working on a project where a website needs to exchange complex and confidential (and thus encrypted) data with other systems. The data includes personal information, technical drawings, public documents etc. We would prefer to avoid the Request-Reply pattern to the dependent systems (and there are a LOT of them), as that would create an awful lot of empty traffic. On the other hand, I am not sure that a pure Publisher/Subscriber pattern would be apropriate -- mainly because of the complex and bulky nature of the data to be exchanged. For that reason we have discussed the possibility of a "publish/subscribe/request" solution. The Publish/Subscribe part would be to publish a message to the dependent systems, that something is ready for pickup. The actual content is then picked up by old-school Request-Reply action. How does this sound to you?? Regards, Morten

• Making profit from a social network

  - by James P.

  This follows similar questions but I'd like to see if anything particular comes out of it due to the nature of site. In short, I've taken up the role of webmaster for a small social network site and wish to make it profitable to at least cover the running costs. The site is linked to a commerce and presents are offered to members according to the number of points they've accumulated through various actions. The site is running on shared hosting so it's probably dirt cheap but the presents can be expensive as a whole and some money has already been invested into the project. One idea I have is to seek some sponsors that would be willing to offer presents or special offers in return for publicity. I don't know if this will be easy or not. I'm also looking into adapting hosting to perhaps move static files to a cheaper online storage medium (see Ideas for reducing storage needs and/or costs (lots of images)). Other suggestions are welcome.

• Is reference to bug/issue in commit message considered good practice?

  - by Christian P

  I'm working on a project where we have the source control set up to automatically write notes in the bug tracker. We simply write the bug issue ID in the commit message and the commit message is added as a note to the bug tracker. I can see only a few downsides for this practice. If sometime in the future the source code gets separated from the bug tracking software (or the reported bugs/issues are somehow lost). Or when someone is looking in the history of commits but doesn't have access to our bug tracker. My question is if having a bug/issue reference in the commit message is considered good practice? Are there some other downsides?

• Is an 'if password == XXXXXXX' enough for minimum security?

  - by Morgan Herlocker

  If I create a login for an app that has middle to low security risk (in other words, its not a banking app or anything), is it acceptable for me to verify a password entered by the user by just saying something like: if(enteredPassword == verifiedPassword) SendToRestrictedArea(); else DisplayPasswordUnknownMessage(); It seems to easy to be effective, but I certainly would not mind if that was all that was required. Is a simple check on username/password combo enough? Update: The particular project happens to be a web service, the verification is entirely server side, and it is not open-source. Does the domain change how you would deal with this?

• What label of tests are BizUnit tests?

  - by charlie.mott

  BizUnit is defined as a "Framework for Automated Testing of Distributed Systems.  However, I've never seen a catchy label to describe what sort of tests we create using this framework. They are not really “Unit Tests” that's for sure. "Integration Tests" might be a good definition, but I want a label that clearly separates it from the manual "System Integration Testing" phase of a project where real instances of the integrated systems are used. Among some colleagues, we brainstormed some suggestions: Automated Integration Tests Stubbed Integration Tests Sandbox Integration Tests Localised Integration Tests All give a good view of the sorts of tests that are being done. I think "Stubbed Integration Tests" is most catchy and descriptive. So I will use that until someone comes up with a better idea.

• What is a good use case for scala?

  - by Usman Ismail

  In a current project we have setup the build so that we could mix Java and Scala. I would like to use more Scala in our code base to make the code more readable and concise. In the process also learn the language by handing over real features. So I plan to use Scala for some classes to showcase its benefits and convince other devs to look into using Scala too. For a rest based web server or a program in general what kind of code structures lend themselves to Scala's functional programming style.

• Game development: Pre-production stage

  - by piers

  I´m starting up a new project. It´s going to be a web browser game, developed using HTML5, JavaScript and CSS3. I have some general questions regarding the process of game developing. Should you know everything about your game by the time you start writing the first lines of code? I mean should you know all the details, all the things the player can and can not do? Basically: should you be done writing down new ideas before you begin coding? I understand the pre-production process is about documenting, doing research etc. What does that mean? Does it mean I should open up Word and write down everything about the game? For example what should happen when you click on different things etc. Thanks for your help!

• What does Symfony Framework offer that Zend Framework does not?

  - by Fatmuemoo

  I have professionally working with Zend Framework for about a year. No major complaints. With some modifications, it has done a good job. I'm beginning to work on a side project where I want to heavily rely on MongoDb and Doctrine. I thought it might be a good idea to broaden my horizons and learn another enterprise level framework. There seems to be a lot a buzz about Symfony. After quickly looking over the site and documentation, I must say I came away pretty underwhelmed. I'm woundering what, if anything, Symfony has to offer that Zend doesn't? What would the advantage be in choosing Symfony?

• How to coach a developer with dyslexia to improve his spelling and grammar capabilities?

  - by Uwe Keim

  Just having read this question regarding developers with dyslexia, I still have some open questions on how to deal with it: I am working on a project sinc approx. 6 month with a new developer who just finished university. I see that the code quality is high, what he's missing is the ability to write texts (even short ones) in an error-free manner (both, syntax and grammar errors). He is working on some UI stuff (VS.NET 2010, ASP.NET 4) and, beside coding, has to write short text for labels, buttons, grid view headers, page titles, etc. Since even those texts have errors inside, no matter how much I try to discuss the need for a professional, text-error-free UI, he seems to not manage to get this right, although he really tries. So my questions are: Are there any hints how he (or I) should proceed to enhance the text quality? Do you know any tools (like inline spell checkers) for VS.NET to highlight syntax and grammar errors? (We are working on a German-only UI, if this is important to know)

• Are there web frameworks/tools that optimize for speed of development?

  - by Ahmet Yildirim

  I've been a PHP web developer for about 2 and a half years now. I have started using CodeIgniter framework to shorten development process a while ago. I developed 4 websites using CodeIgniter. It has been really tiring and boring due to code-repetition. Code repetition was vast on form handling functions in controllers.So in my last project , i developed a general form input handling function.This lead a realisation that it could get even faster by more automation. What i think i lack in my development is using CRUD & Code Generation tools. But i am wondering if there is any other utilities that shortens development process. Which web development language or framework more inclined towards code generation utilities?

• Spring can commit Transaction in finally block with RunTimeException in try block [migrated]

  - by Chance Lai

  The project used Spring + Hibernate Sample code: public void method(){ try{ dao.saveA(entityA); throw RuntimeException; dao.saveB(entityB); }catch(RuntimeException e){ throw e; }finally{ dao.saveC(entityC) } } Finally, just entityC will be saved in database in test. I think saveA, saveB, saveC in the same transaction,they should not be committed. In this case, I want to know why entityC is committed. How does Spring do this in the finally block?

• Eliminating Downtime During Database Upgrades: A Customer Case Study

  - by irem.radzik(at)oracle.com

  Planned outages, such as database, OS, hardware upgrades and migrations, are a fact of life. Even though they are "planned" and many of them are performed during "off business hours", they can still interrupt operations-- especially for global operations and online businesses. For this reason many IT organizations postpone these critical infrastructure improvement projects, which in turn result in delays in advancing business operations. This week, on Thursday January 13th, we will host a free webcast on this topic, and will feature Oracle GoldenGate's customer Atmos Energy. Atmos Energy implemented Oracle GoldenGate for eliminating downtime during their database upgrade from Oracle Database 8.1.7 to Oracle Database 11.1.0.7. Jos Francis, Lead DBA for Atmos, and Ronald Nedd, Sr. DBA for Atmos, will be presenting their database upgrade project and their solution architecture. Join us at this live webcast and hear from our customer and product management how to eliminate planned outages with Oracle GoldenGate's real-time, heterogeneous data replication capabilities.

• Not getting paid for hours you've worked?

  - by Mercfh

  So I was reading from a previous thread about App vs Game Development Here Which brought me to this site: Clicky Alot of it talked about devs working something like 85 hours a week.....and not getting paid overtime, or anything. Just getting paid for the 40 hours.....Is this normal for most software companies? I mean where I work im only an entry level guy....but I get overtime, and Anything over 40 hours is considered this. But it got me thinking "Holy crap" I could never do that. My FREE time is important to me. But is this commonplace in most software companies? or...more a rarity to certain types (game development, etc) Cause it got me scared! Like I understand having to put some extra hours in for a project......but like 80! thats ridiculous.

• Who is likely to need the most this high-quality, measurable, reliable approach to software? [closed]

  - by Marek Cruz

  Software engineering is the application of principles of engineering to software. Trouble is, most of those who like to flatter with the title "software engineer" don't do that. They just keep writing code and patching it until it's stable enough to foist off on users. That's not software engineering. Who is likely to need the most the practice of software engineering? (with all the project planning, requirements engineering, software design, implementation based on the design, testing, deployment, awareness of IEEE standards, metrics, security, dependability, usability, etc.)

• How do I simplify terrain with tunnels or overhangs?

  - by KKlouzal

  I'm attempting to store vertex data in a quadtree with C++, such that far-away vertices can be combined to simplify the object and speed up rendering. This works well with a reasonably flat mesh, but what about terrain with overhangs or tunnels? How should I represent such a mesh in a quadtree? After the initial generation, each mesh is roughly 130,000 polygons and about 300 of these meshes are lined up to create the surface of a planetary body. A fully generated planet is upwards of 10,000,000 polygons before applying any culling to the individual meshes. Therefore, this second optimization is vital for the project. The rest of my confusion focuses around my inexperience with vertex data: How do I properly loop through the vertex data to group them into specific quads? How do I conclude from vertex data what a quad's maximum size should be? How many quads should the quadtree include?

• Ubuntu 12.04 "Shutdown" or "Restart" logs out

  - by jenls

  While logged in as a sudo user, click the right top power icon, then select and click "Shutdown" menu, it comes up with a dialog asking if I want to close all programs. The dialog has two options: restart or shutdown. Choose either one logs me out. Syslog has the following line about restart: WARNING: Unable to restart system: Authorization is required This happened after I installed NTP and some OpenStack packages while working in a prototype project. My Ubuntu's software is up to date as of this writing. Anyone encountered the same problem in 12.04?

• Avoid GPL violation by moving library out of process

  - by Andrey

  Assume there is a library that is licensed under GPL. I want to use it is closed source project. I do following: Create small wrapper application around that GPL library that listens to socket, parse messages and call GPL library. Then returns results back. Release it's sources (to comply with GPL) Create client for this wrapper in my main application and don't release sources. I know that this adds huge overhead compared to static/dynamic linking, but I am interested in theoretical way.

• Best Game Engine/Framework and Language for 2D actor/sprite intensive game

  - by Grungetastic

  I'm new to the game dev world. I have a rather large project in mind (I learn by setting myself challenges :P ) and I'm wondering what the best engine/framework/language is for a 2D game with thousands of sprites/actors on screen at a time. Bare metal type stuff. I need to still be able to zoom in and out with that many actors at once. This game will have no 3D elements. Any thoughts? Suggestions?

• How to have a maintainable and manageable Javascript code base

  - by dade

  I am starting a new job soon as a frontend developer. The App I would be working on is 100% Javascript on the client side. all the server returns is an index page that loads all the Javascript files needed by the app. Now here is the problem: The whole of the application is built around having functions wrapped to different namespaces. And from what I see, a simple function like rendering the HTML of a page can be accomplished by having a call to 2 or more functions across different namespace... My initial thought was "this does not feel like the perfect solution" and I can just envisage a lot of issues with maintaining the code and extending it down the line. Now I would soon start working on taking the project forward and would like to have suggestions on good case practices when it comes to writing and managing a relatively large amount of javascript code.

• What is 'work' in the Pomodoro Technique?

  - by Sachin Kainth

  I have just started to use Pomodoro today and I am trying to work out what I should and should not do during my 25 minute work time. For my 25 minute work stint I started to write some code and realised that I had done something similar in a related project so I opened that solution to copy and paste that existing code. Question is, is this allowed? Also, if during my 25 minutes I realise that there is an important work-related email that I need to send can I do that or should that wait for the next 25 minutes or the break. I am writing this question during my, now extended, 5 minute break. Is this work or is it a break? I really would appreciate some guidance as I really want to use Pomodoro to focus better on my work. Another thing that happened to me was that a Adobe AIR update alert came up on my desktop during the 25 minutes. Should I ignore such things until the break? Sachin

• What's the best Wireframing tool?

  - by Strae

  I'm looking for something similar to iPlotz or Mockup. I've found the Pencil Project, but it requires xulrunner-1.9 (which seems to be incompatible with xulrunner-1.9.2) in order to run as a standalone application. It can be used as a firefox plugin... but it is a bit slower. The error on my desktop (Ubuntu 10.04) is: Could not find compatible GRE between version 1.9.1 and 1.9.2.* Does anyone know other software? Edit: Open-source software is preferred, and it doesn't matter whether or not it's free.
