• is it better to spend my free time mastering a language I work with or learning a new one?

  - by edthethird

  I work full time on an android project and am very comfortable with both java and the android framework. On a good day, I would rate my abilities at an 8, and maybe a 7 on a bad day. I've recently found myself with more free time then I'm used too, so I have been working on a lot of personal projects. I am beginning to wonder what others think about this; is it worth my time to continue experimenting and pushing Android, or would I be better off learning another language? What do you all think about this? What would you do with more free time and energy than you know what to do with?

• What are the best social places for programmers to interact?

  - by Chevex

  I know this is not really the right place for this type of question, but I figure it will get me started and hopefully won't be closed right off the bat. I love the programming industry a lot, but I don't have many colleagues that aren't introverted and/or anti-social, or self-centered. What are some good places online to find programming friends that I could share my adventures with? I love stack overflow but it is more technical and doesn't really allow you to put up a personal project just for people to see and critique. Any suggestions? A good forum would be great! The only ones I can find are usually full of inexperienced people who just "want" to be a programmer. I'm looking more for a place who's members are already programmers discussing programming topics.

• Do employers prefer software engineering over CS majors?

  - by Joey Green

  I'm in grad school at a university that was one of the first to have a software engineering accredited program. My undergrad is in CS. An employer recently recruited at our university and hired 5 SE majors. None of them were CS. Do employers prefer software engineering majors? The reason I ask is because I can focus on many different areas during my graduate studies and really want to take the classes that will help me land a great job. Right now I'm either going to use CUDA and parallelize an advanced ray-tracer for a graduate project or do research on non-photo-realistic rendering in augmented reality. Pursuing these would leave very little SE classes in my schedule. If I went the software engineering route, I would probably either do research into data-oriented programming or software design complexity. Sometimes I think when I'm 40 and look back will it matter at all? For some reason I'm thinking not.

• Infrastructure and Platform As A Service in Private Cloud at Lawrence Livermore National Laboratory

  - by Anand Akela

  Scientists at the National Ignition Facility (NIF)— the world’s largest laser, at the Lawrence Livermore National Laboratory (LLNL)— need research environment that requires re-creating the physical environment and conditions that exist inside the sun. They have built private cloud infrastructure using Oracle VM and Oracle Enterprise Manager 12c to provision such an environment for research.  Tim Frazier of LLNL joined the "Managing Your Private Cloud With Oracle Enterprise Manager' session at Oracle Open World 2012 and discussed how the latest features in Oracle VM and Oracle Enterprise Manager 12c enables them to accelerate application provisioning in their private cloud. He also talked about how to increase service delivery agility, improve standardized roll outs, and do proactive management to gain total control of the private cloud environment. He also presented at the "Scene and Be Heard Theater" at Oracle OpenWorld 2012 and shared a lot of good information about his project and what they are doing in their private cloud environment.

• Support / Maintenance documentation for development team

  - by benwebdev

  Hi, I'm working in the Development dept (around 40 developers) for a large E-Commerce company. We've grown quickly but have not evolved very well in the field of documenting our work. We work with an Agile / Scrum-like methodology with our development and testing but documentation seems to be neglected. We need to be able to make documentation that would aid a developer who hasnt worked on our project before or was new to the company. We also have to create more high level information for our support department to explain any extra config settings and fixes of known issues that may arise, if any. Currently we put this in a badly put together wiki, based on an old Sharepoint / TFS site. Can anyone suggest some ideal links or advice on improving the documentation standard? What works in other companies? Has anyone got avice on developing documentation as part of an agile process? Many thanks, ben

• Reverse rendering of Urdu fonts

  - by Syed Muhammad Umair

  I am working on a project that is based on Urdu language in Ubuntu platform. I'm using Python language and have almost achieved my task. The problem is that, the Urdu text is rendered in reverse order. For example, consider the word ??? (which means work) consisting of the three letters: ? , ? , and ? The output is rendered in reverse order as ??? consisting of the three letters: ?, ?, and ? When copying this text to Open Office or opening the generated XML file in Firefox, the generated result is absolutely desired. How can this problem be solved?

• Getting rid of getting stuck often [closed]

  - by Pankaj Upadhyay

  I have been working with C# and .NET for around 2-3 years. But, still i get stuck too often. My project includes few simple websites(asp.net) in the early parts and then a desktop application for cotton transaction management(wpf). And right now, I am building a price compare website (asp.net MVC). Along the lines, I have read quite few books on C# and .NET, but still I get stuck very often. What pisses me is that the problems I get stuck in aren't very typical or hard. You can get a better idea by visiting my questions page on SO. After looking at my question lists, do you also feel that my basis or knowledge as a programmer are weak ? If so, How can i find a remedy to this problem ? And How can I stop getting stuck too often for simpler problems.

• Two internships at the same time -- good or bad?

  - by Karl

  I had no internship a few months ago, so I basically went on a 'resume mailing' spree and emailed a lot of companies that I was interested in working for and that had my line of work. This didn't prove futile until a company accepted me into their internship program but said that I would be working remotely. I had no problem with that, the project was good and I was interested. Now I have another internship at a company that is close to my home and I don't want to miss it at all! I can manage both internships side-by-side. In the day, I will do the internship that is closer to my home and at night (and other times), I can manage the remote internship. My question is -- should I both? I am particularly interested in how two internships at the same time are viewed. Would it look good or bad? PS: Neither is paying me anything, so money is not a factor.

• PowerShell, Start-Job, -ScriptBlock = sad panda face

  - by AaronBertrand

  I am working on a project where I am using PowerShell to collect a lot of performance counters from a lot of servers. More on that later. For now I wanted to highlight an important lesson I learned when trying to use Start-Job to call a PS script using -ScriptBlock and passing in parameters. This could be a comedy of errors if you haven't come across it before, so I thought it might be useful to throw up a quick post about it. To keep things simple, let's say I am calling a script with two parameters,...(read more)

• What to choose API based server or Socket based server for data driven application

  - by Imdad

  I am working on a project which has a Desktop Application for MAC/COCOA, a native application for iPhone another native application in iPad. All the application do almost same thing. The applications are data driven applications. Every communication to server is made via a restful API developed in PHP. When a user logs in a lot of data is fetched from server. And to remain in sync with server pooling is done. As there are lot of data to pool it makes application slower and un-reliable. A possible solution that comes into my mind is to use Socket based server. My question is that will it reasonably improve the performance? And which technology (of sockets) will be good as a server side solution for data driven application? I have heard a lot about Node.js. Please give your suggestions.

• Day 1 - Finding Like Minds

  - by dapostolov

  So, is being a Game Developer any different from being an IT Developer? I picture a poorly lit environment where I get to purchase my own desk lamp; I'm thinking one of those huge lava lamps that pump out so much heat you could fry an egg on it. To my right: a "great wall" of empty coke cans dwarf me. Eating my last slice of pizza I look across my desk to see a fellow developer with a smug look on his face;  he's just coded his latest module for the game and it looks like he's in nirvana. My duty, of course, is to remind him to keep focused on the job at hand. So, picking up my trusty elastic and aerodynamically crafted paper bullet I begin a 10 minute war of welts and laughter which is promptly abrupted by our Project Manager demanding more details from our morning Scrum meeting. After providing about 5 minutes of geek speak and several words of comfort to make his eyes glaze over...it hits me, the idea for the module...beckoning my developer friend over, we quickly shoo the Project Manager away and begin our brainstorming frenzy ... now, where'd I put that full can of coke? OK. OK. This isn't probably the most ideal game developer environment, but it definitely sounds fun to me...and from what I gather is nothing like most game development companies. But I'm not doing this blog series to "go pro"; like I stated in my first post I want to make a 2D game from an idea my best friend and I drummed up long, long ago. I'm in this for the passion AND I want to see how easy it is for us .Net Developers to create a game. So where do I start? Where can I find like minded individuals? What technologies are there? What do I need to make a video game? The questions are endless....AND...since I already have an idea ... lets start with ... Technology (yes, I'm a geek, live with it...) Technology OK. Predominantly, games are still made in C++ or even C. I'm not sure how much assembly code is floating around lately, however, that is not my concern. I do know C / C++ from my past, enough to even get me by, but I'm mainly interested in a recent, not-so-new, technology called XNA. What is XNA? XNA allows us .Net Developers to make 2D / 3D games for windows, Xbox*, and Windows Mobile 7*. * = for a nominal fee *cough* The following link is your one stop shop to XNA game development: http://creators.xna.com/en-US/education/gettingstarted The above site hosts information such as: - getting started - a sample/instructional shooter game in 2D / 3D with code (if I'm taking too long for you in this blog series) - downloads - starter kits... http://creators.xna.com/en-US/education/starterkits/ And of course...forums. You can also subscribe and pay for their premium membership which gets you some pretty awesome tutorials, resources, downloads, and premium community support. Some general Wiki information about XNA: http://en.wikipedia.org/wiki/XNA_%28Microsoft%29 Community Support OK. Let's move on to industry and community support. Apart from XNA, there are some really cool sites out there, I just haven't found all of them yet. However, I found a really cool Game Development website called Gamastura. You can click on the following link to get you there: http://www.gamasutra.com/ The site is 100% dedicated to "The Art & Business of Making Games". Armed with blogs, twitter, jobs/resumes and most importantly industry news; one could subscribe to the feed and got lost in the wealth of information it provides. On a side note: I remember Gamasutra being around when my best friend and I wanted to make a video game...meaning, they've been around for a while now. I think the most beneficial aspect of this site is to understand the industry you want to get into. Otherwise, it's just a cool site to keep up to date with the industry in general. Another Community Support option is LinkedIn. Amongst the land of extremely bloated achievements and responsibilities lay 3 groups (that I have found) that deal with game development.: http://www.linkedin.com/groups?gid=59205 - Game Developers http://www.linkedin.com/groups?gid=824817 - DirectX Game Developer Network http://www.linkedin.com/groups?gid=756587 - DirectX Developers The Game Developers group in LinkedIn is by far the most active of the three and could possibly provide a wealth of support. What I've done thus far: - I lightly researched the XNA technology - I looked around for some community sites to assist me - I downloaded the XNA Game Studio 3.1 on my PC and installed it on my IDE - I even tried both tutorials! http://creators.xna.com/en-US/education/gettingstarted/bgintro/chapter1   Best Regards D.

• I prefer C/C++ over Unity and other tools: is it such a big downer for a game developer?

  - by jokoon

  We have a big game project using Unity at school. There are 12 of us working on it. My teacher seems to be convinced it's an important tool to teach students, since it makes students look from the high level to the lower level. I can understand his view, and I'm wondering: Is unity such an important engine in game development companies? Are there a lot of companies using it because they can't afford to use something else? He is talking like Unity is a big player in game making, but I only see it fit small indie game companies who want to do a game as fast as possible. Do you think Unity is of that much importance in the industry? Does it endanger the value of C++ skills? It's not that I don't like Unity, it's just that I don't learn anything with it, I prefer to achieve little steps with Ogre or SFML instead. Also, we also have C++ practice exercises, but those are just practice with theory, nothing much.

• WPF Databinding- Part 2 of 3

  - by Shervin Shakibi

  This is a follow up to my previous post WPF Databinding- Not your fathers databinding Part 1-3 you can download the source code here  http://ssccinc.com/wpfdatabinding.zip Example 04   In this example we demonstrate  the use of default properties and also binding to an instant of an object which is part of a collection bound to its container. this is actually not as complicated as it sounds. First of all, lets take a look at our Employee class notice we have overridden the ToString method, which will return employees First name , last name and employee number in parentheses, public override string ToString()        {            return String.Format("{0} {1} ({2})", FirstName, LastName, EmployeeNumber);        }   in our XAML we have set the itemsource of the list box to just  “Binding” and the Grid that contains it, has its DataContext set to a collection of our Employee objects. DataContext="{StaticResource myEmployeeList}"> ….. <ListBox Name="employeeListBox"  ItemsSource="{Binding }" Grid.Row="0" /> the ToString in the method for each instance will get executed and the following is a result of it. if we did not have a ToString the list box would look  like this: now lets take a look at the grid that will display the details when someone clicks on an Item, the Grid has the following DataContext DataContext="{Binding ElementName=employeeListBox,            Path=SelectedItem}"> Which means its bound to a specific instance of the Employee object. and within the gird we have textboxes that are bound to different Properties of our class. <TextBox Grid.Row="0" Grid.Column="1" Text="{Binding Path=FirstName}" /> <TextBox Grid.Row="1" Grid.Column="1" Text="{Binding Path=LastName}" /> <TextBox Grid.Row="2" Grid.Column="1" Text="{Binding Path=Title}" /> <TextBox Grid.Row="3" Grid.Column="1" Text="{Binding Path=Department}" />   Example 05   This project demonstrates use of the ObservableCollection and INotifyPropertyChanged interface. Lets take a look at Employee.cs first, notice it implements the INotifyPropertyChanged interface now scroll down and notice for each setter there is a call to the OnPropertyChanged method, which basically will will fire up the event notifying to the value of that specific property has been changed. Next EmployeeList.cs notice it is an ObservableCollection . Go ahead and set the start up project to example 05 and then run. Click on Add a new employee and the new employee should appear in the list box.   Example 06   This is a great example of IValueConverter its actuall a two for one deal, like most of my presentation demos I found this by “Binging” ( formerly known as g---ing) unfortunately now I can’t find the original author to give him  the credit he/she deserves. Before we look at the code lets run the app and look at the finished product, put in 0 in Celsius  and you should see Fahrenheit textbox displaying to 32 degrees, I know this is calculating correctly from my elementary school science class , also note the color changed to blue, now put in 100 in Celsius which should give us 212 Fahrenheit but now the color is red indicating it is hot, and finally put in 75 Fahrenheit and you should see 23.88 for Celsius and the color now should be black. Basically IValueConverter allows us different types to be bound, I’m sure you have had problems in the past trying to bind to Date values . First look at FahrenheitToCelciusConverter.cs first notice it implements IValueConverter. IValueConverter has two methods Convert and ConvertBack. In each method we have the code for converting Fahrenheit to Celsius and vice Versa. In our XAML, after we set a reference in our Windows.Resources section. and for txtCelsius we set the path to TxtFahrenheit and the converter to an instance our FahrenheitToCelciusConverter converter. no need to repeat this for TxtFahrenheit since we have a convert and ConvertBack. Text="{Binding  UpdateSourceTrigger=PropertyChanged,            Path=Text,ElementName=txtFahrenheit,            Converter={StaticResource myTemperatureConverter}}" As mentioned earlier this is a twofer Demo, in the second demo, we basically are converting a double datatype to a brush. Lets take a look at TemperatureToColorConverter, notice we in our Covert Method, if the value is less than our cold temperature threshold we return a blue brush and if it is higher than our hot temperature threshold we return a redbrush. since we don’t have to convert a brush to double value in our example the convert back is not being implemented. Take time and go through these three examples and I hope you have a better understanding   of databinding, ObservableCollection  and IValueConverter . Next blog posting we will talk about ValidationRule, DataTemplates and DataTemplate triggers.

• Do TODO comments make sense?

  - by Ivan Crojach Karacic

  I am working on a fairly big project and got the task to do some translations for it. There were tons of labels that haven't been translated and while I was digging through the code I found this little piece of code //TODO translations This made me think about the sense of these comments to yourself (and others?) because I got the feeling that most developers after they get a certain piece of code done and it does what it's supposed to do they never look at this until they have to maintain it or add new functionality. So that this TODO will be lost for a long time. Does it make sense to write this comments or should they be written on a whiteboard/paper/something else where they remain in the focus of developers?

• Controllers in CodeIgniter

  - by Dileep Dil

  I little bit new to the CodeIgniter framework and this is my first project with this framework. During a chat on StackOverflow somebody said that we need to make controllers tiny as possible. Currently I have a default controller named home with 1332 lines of codes (and increasing) and a model named Profunction with 1356 lines of codes (and increasing). The controller class have about 46 functions on it and also with model class. I thought that Codeigniter can handle large Controllers or Models well, is there any problem/performance issue/security issues regarding this?

• Using JPA 2.0 with WebLogic Server 10.3.4 and Eclipse

  - by greg.stachnick

  Beginning in Oracle Enterprise Pack for Eclipse (OEPE) 11.1.1.6.1, we introduced a new feature for WebLogic Server configuration called Server Extensions. Similar in concept to project facets, Server Extensions allow us to install additional technologies, libraries, configurations, etc into an existing server runtime. WebLogic Server 10.3.4 introduces new support for Java Persistence 2.0, the new JEE 6 standard entity access. In order to start developing JPA 2.0 applications with WebLogic Server 10.3.4, a SmartUpdate patch must be applied to add and configure the EclipseLink libraries. More information on the manual EclipseLink installation and configuration can be found here. OEPE provides a Server Extension for JPA 2.0, making the addition and configuration of JPA 2.0 and EclipseLink much easier. When defining a new WebLogic Server 10.3.4 configuration, simply click the Install link for Java Persistence 2.0 and OEPE will take care of the WebLogic Server enablement for JPA 2.0.

• When should I tell my boss that I'm thinking about looking for another job?

  - by BeachRunnerJoe

  I'm thinking about looking around for another job, but I don't know when I should tell my boss because I would like to see what kind of opportunities I can land before I even mention it. The reason I'm reluctant to tell him right away is I'm afraid he'll begin the process of replacing me. If I don't tell him while I'm looking around, then I can't use him as a reference and he'd most likely give a great recommendation. If I were to leave and go work for someone else, it wouldn't be until after I finish my current project which ends in two months because I don't want to screw anyone over. How would you approach him about this and when? Thanks in advance for your wisdom!

• How is time calculation performed by a computer?

  - by Jorge Mendoza

  I need to add a certain feature to a module in a given project regarding time calculation. For this specific case I'm using Java and reading through the documentation of the Date class I found out the time is calculated in milliseconds starting from January 1, 1970, 00:00:00 GMT. I think it's safe to assume there is a similar "starting date" in other languages so I guess the specific implementation in Java doesn't matter. How is the time calculation performed by the computer? How does it know exactly how many milliseconds have passed from that given "starting date and time" to the current date and time?

• 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.

• Building a custom Xsession with VNC access

  - by Disco

  I have a small project where I'll need to build a very minimal X11 environnement for a cyber coffee kind shop. My idea is to have a simple server which will create a dozen of VNC Daemon listening on a different port (each port = one client). The server is working, i can connect using vnc to different port. Now i'm looking for a solution to create a customized desktop for each client; with a bare minimum of apps which i want to be able to add for each user. Like user1 will have app1 and app2, user2 will have app1 only etc. I plan to use openbox as a WM but no clue on 'how' to add custom icons on the desktop of it. Any clue, starting point would be interesting.

• Version control and personal configuration file

  - by Erel Segal Halevi

  Our project uses a user-specific configuration file. This file is currently not in version control, since it is different for each user. The problem is, whenever a developer adds a new module that requires configuration, or changes the name of an existing modules, the other developers get errors because their private configuration files are not updated. To solve the problem, we thought of working with two configuration files: a default/global configuration file that will be in version control and will be updated regularly by each developer that adds a new module, and a private configuration file that will be kept out of version control and will contain only the user-specific changes. However, this still seems like an ad-hoc solution. Can you propose a better solution? What do the professionals do?
