  • Best Practice - XML To Excel

    - by MemLeak
    I've to read a big XML file with a lot of information. Afterwards I extract the needed information (~20 Points(columns) / ~80 relevant Data (rows, some of them with subdatasets) and write them out in a Excel File. My Question is how to handle the extraction (of unused Data) part, should I copy the whole file and delete the unused parts, and then write it to excel or is it a good approach to create Objects for each column? should I write the whole xml to excel and start to delete rows in excel? What would be performant and a acceptable solution?

  • Accessing Repositories from Domain

    - by Paul T Davies
    Say we have a task logging system, when a task is logged, the user specifies a category and the task defaults to a status of 'Outstanding'. Assume in this instance that Category and Status have to be implemented as entities. Normally I would do this: Application Layer: public class TaskService { //... public void Add(Guid categoryId, string description) { var category = _categoryRepository.GetById(categoryId); var status = _statusRepository.GetById(Constants.Status.OutstandingId); var task = Task.Create(category, status, description); _taskRepository.Save(task); } } Entity: public class Task { //... public static void Create(Category category, Status status, string description) { return new Task { Category = category, Status = status, Description = descrtiption }; } } I do it like this because I am consistently told that entities should not access the repositories, but it would make much more sense to me if I did this: Entity: public class Task { //... public static void Create(Category category, string description) { return new Task { Category = category, Status = _statusRepository.GetById(Constants.Status.OutstandingId), Description = descrtiption }; } } The status repository is dependecy injected anyway, so there is no real dependency, and this feels more to me thike it is the domain that is making thedecision that a task defaults to outstanding. The previous version feels like it is the application layeer making that decision. Any why are repository contracts often in the domain if this should not be a posibility? Here is a more extreme example, here the domain decides urgency: Entity: public class Task { //... public static void Create(Category category, string description) { var task = new Task { Category = category, Status = _statusRepository.GetById(Constants.Status.OutstandingId), Description = descrtiption }; if(someCondition) { if(someValue > anotherValue) { task.Urgency = _urgencyRepository.GetById (Constants.Urgency.UrgentId); } else { task.Urgency = _urgencyRepository.GetById (Constants.Urgency.SemiUrgentId); } } else { task.Urgency = _urgencyRepository.GetById (Constants.Urgency.NotId); } return task; } } There is no way you would want to pass in all possible versions of Urgency, and no way you would want to calculate this business logic in the application layer, so surely this would be the most appropriate way? So is this a valid reason to access repositories from the domain?

  • What would you add to Code Complete 3rd Edition?

    - by Peter Turner
    It's been quite a few years since Code Complete was published. I really love the book, I keep it in the bathroom at the office and read a little out of it once or twice a day. I was just wondering for the sake of wonderment, what kinds of things need to be added to Code Complete 3e, and for the sake of reductionism, what kinds of things would be removed. Also, what languages would you use for code examples?

  • Can I take up another part-time job when working with a typical IT company in India? [closed]

    - by learnerforever
    Hi, I know that this kind of question might depend from policies of company to company, but how does it look like in a typical IT company in India? Can I take up another part-time job when working full time in a typical private IT company in India? Is there any indian employement law preventing it(for whatever reason)? This part-time job could be a job on weekends or some online part-time freelancing programming job, which I manage to do on weekends or on weekdays after office hours. Thanks,

  • What are some small, but extendable game ideas to use for inspiration?

    - by Earlz
    I recently came across the game Dopewars(or more generically, Drugwars). Now this is an extremely simple game to implement. A trivial basic implementation could be done in a couple of days, at the most. And it's extremely extendable. Now, my question is what other games are out there that follow this same kind of "difficulty level" for implementation? A game that is actually entertaining, yet trivial to implement, and can easily be extended?

  • The worst anti-patterns you have came across.

    - by ?????????
    What are the worst anti-patterns you have came across in your career as a programmer? I'm mostly involved in java, although it is probably language-independent. I think the worst of it is what I call the main anti-pattern. It means program consisting of single, extremely big class (sometimes accompanied with a pair of little classes) which contains all logic. Typically with a big loop in which all business logic is contained, sometimes having tens of thousands of lines of code.

  • How to use multiple monitors effectivelly

    - by maaartinus
    I'm currently using a single monitor, since I see no value in something like this mentioned in this answer. It may be a good exercise for my neck, but besides of this I see no use therein at all. This amounts to 5760x1200 pixels, which is nearly 7M pixels, just fantastic, except for me not being a cyklop-han. The ratio of 24:5 is IMHO too bad for this to be usable. I don't even think that two 16:10 monitors side by side is a good idea. I never tried so I may be completely wrong, but I suppose that the 4:3 ratio would be much better for this. Or even 1:1, but no such thing is available (with some exceptions, either very expensive or very low resolution). Does anybody use two monitors arranged vertically (resulting in 16:20)? or two pivoted monitors side by side (resulting in 20:16)? or another such variant?

  • Gerrit, git and reviewing whole branch

    - by liori
    I'm now learning Gerrit (which is the first code review tool I use). Gerrit requires a reviewed change to consist of a single commit. My feature branch has about 10 commits. The gerrit-prefered way is to squash those 10 commits into a single one. However this way if the commit will be merged into the target branch, the internal history of that feature branch will be lost. For example, I won't be able to use git-bisect to bisect into those commits. Am I right? I am a little bit worried about this state of things. What is the rationale for this choice? Is there any way of doing this in Gerrit without losing history?

  • Configure Jenkins and Tomcat using Puppet on Vagrant

    - by ex3v
    I'm playing with setting up my first Spring + jenkins + Tomcat CI dev environment. For now it's just a test/fun phase, but in the near future I'll be starting new project with my coworkers. That's the reason that I want development environment virtualized and exactly te same on every development machine, as well as on production server. I choosen to use Vagrant and to try to write puppet scripts that not only install everything, but also configure everything so each of us will have the same jenkins plugins, same jenkins and tomcat login and password, and literally after calling vagrant up we are ready to work. What I managed to do so far is installation of stuff needed and port forwarding. My vagrantfile looks like this (comments stripped): VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "precise32" config.vm.box_url = "http://files.vagrantup.com/precise32.box" config.vm.network :forwarded_port, guest: 80, host: 8090 config.vm.network :forwarded_port, guest: 8080, host: 8091 config.vm.network :private_network, ip: "192.168.33.10" config.vm.provision :puppet do |puppet| puppet.manifests_path = "puppet/" puppet.manifest_file = "default.pp" puppet.options = ['--verbose'] end end And this is my puppet file: Exec { path => [ "/bin/", "/sbin/" , "/usr/bin/", "/usr/sbin/" ] } class system-update { exec { 'apt-get update': command => 'apt-get update', } $sysPackages = [ "build-essential" ] package { $sysPackages: ensure => "installed", require => Exec['apt-get update'], } } class tomcat { package { "tomcat": ensure => present, require => Class["system-update"], } service { "tomcat": ensure => "running", require => Package["tomcat"], } } class jenkins { package { "jenkins": ensure => present, require => Class["system-update"], } service { "jenkins": ensure => "running", require => Package["jenkins"], } } include system-update include tomcat include jenkins Now, when I hit vagrant provision and go to http://localhost:8091/ I can see jenkins running, so above script works good. Next step is configurating jenkins and tomcat by extending above puppet scripts. I'm pretty green when it comes to CI. After wandering around web I've found few tutorials about jenkins configuration (here's one of them). I really want to move configuration presented in this tutorial to puppet file, so when I spread my vagrantfile and puppet file between my coworkers, I will be sure that everyone has exactly te same setup. Unfortunately I'm also green about using puppet, I don't know how to do this. Any help will be apreciated.

  • May I make an installer bundle GPL and payware together?

    - by Volomike
    I have an affiliate marketing client who needs to know if I can program this. Can I do one or both of the following scenarios without violating the GPL license? Scenario A: Make a software installer for a GPL licensed product which includes source, binaries, and license info. The installer also has a checkbox for installing optional software that's payware. (In this case, the payware is free crippleware, but has a registration upsell to provide more features.) The two products will not share libraries or anything else. Scenario B: Same as A, but reversed. So, the installer installs the payware, but there's a checkbox to also install the GPL software. And, again, when you install the GPL software, it comes with binaries, source, and license info.

  • What are unique aspects of a software Lifecycle of an attack/tool on a software vulnerability?

    - by David Kaczynski
    At my local university, there is a small student computing club of about 20 students. The club has several small teams with specific areas of focus, such as mobile development, robotics, game development, and hacking / security. I am introducing some basic agile development concepts to a couple of the teams, such as user stories, estimating complexity of tasks, and continuous integration for version control and automated builds/testing. I am familiar with some basic development life-cycles, such as waterfall, spiral, RUP, agile, etc., but I am wondering if there is such a thing as a software development life-cycle for hacking / breaching security. Surely, hackers are writing computer code, but what is the life-cycle of that code? I don't think that they would be too concerned with maintenance, as once the breach has been found and patched, the code that exploited that breach is useless. I imagine the life-cycle would be something like: Find gap in security Exploit gap in security Procure payload Utilize payload What kind of differences (if any) are there for the development life-cycle of software when the purpose of the product is to breach security?

  • What percentage of revenue would be fair for app stores to take? [closed]

    - by Tyler Collier
    Apple takes 30% of revenue from app sales on the iPhone app store. Now Apple does the same with the Mac app store. Google also takes a 30% cut in the Android Market. These seem pretty steep. What percentage do you think would be fair and good for both you as a developer/vendor and Apple/Google? What's a happier middle ground? 20%? If the answer you give is less than 30% but you are selling apps in the app store or android market, please explain why you are willing to, and what benefits Apple and Google would see from reducing their cuts.

  • Naming boolean field that is a verb

    - by dnhang
    In Java, by convention getter and setter for boolean fields will be isField() and setField(). This works perfectly fine with field names that are adjectives like active, visible, closed, etc. But how do I name a field that has meaning of a verb, like haveChildren? Add _ing to the verb (havingChildren), maybe? Edit: to clarify, I don't have control of the method names (getter and setter), they are auto-generated by the IDE. So what I need is an appropriate field name so that when the IDE generate a getter for it, it make senses. For example, hasChildren is a perfect field name, but when the IDE generate the getter for the field it would be isHasChildren. How do I solve this?

  • running jar in a terminal using axis2

    - by Emilio
    I'm trying to run in the command line a java application distributed in a jar file. It call an axis2 web service, so the jar contains a /axis2client directory with rampart.mar security module. It works fine while I run it in netbeans, but it throws an exception if I try to run it in a terminal using this command: java -jar myfile.jar The Exception: org.apache.axis2.AxisFault: invalid url: //file:/home/xxx/Desktop/myfile.jar!/axis2client/ (java.net.MalformedURLException: no protocol: //file:/home/xxx/Desktop/myfile.jar) As you can see, it's trying to use the /axis2client directory inside the jar, as when I run it in Netbeans, but It fails with a MalformedURLException. I think it's something about the protocol 'file:', probably '//file:/' must be 'file:///'. The problem is that I cannot change this call to the directory because the method that loads the /axis2client directory it's not mine, it's from another library that use my project and include all the axis2 support. So, any idea?? Thanks in advance lads!

  • How to unicode Myanmar texts on Java? [closed]

    - by Spacez Ly Wang
    I'm just beginner of Java. I'm trying to unicode (display) correctly Myanmar texts on Java GUI ( Swing/Awt ). I have four TrueType fonts which support Myanmar unicode texts. There are Myanmar3, Padauk, Tharlon, Myanmar Text ( Window 8 built-in ). You may need the fonts before the code. Google the fonts, please. Each of the fonts display on Java GUI differently and incorrectly. Here is the code for GUI Label displaying myanmar texts: ++++++++++++++++++++++++ package javaapplication1; import javax.swing.JFrame; import javax.swing.JTextField; public class CusFrom { private static void createAndShowGUI() { JFrame frame = new JFrame("Hello World Swing"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); String s = "\u1015\u102F \u103C\u1015\u102F"; JLabel label = new JLabel(s); label.setFont(new java.awt.Font("Myanmar3", 0, 20));// font insert here, Myanmar Text, Padauk, Myanmar3, Tharlon frame.getContentPane().add(label); frame.pack(); frame.setVisible(true); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } } ++++++++++++++++++++++++ Outputs vary. See the pictures: Myanmar3 IMG Padauk IMG Tharlon IMG Myanmar Text IMG What is the correct form? (on notepad) Well, next is the code for GUI Textfield inputting Myanmar texts: ++++++++++++++++++++++++ package javaapplication1; import javax.swing.JFrame; import javax.swing.JTextField; public class XusForm { private static void createAndShowGUI() { JFrame frame = new JFrame("Frame Title"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JTextField textfield = new JTextField(); textfield.setFont(new java.awt.Font("Myanmar3", 0, 20)); frame.getContentPane().add(textfield); frame.pack(); frame.setVisible(true); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } } ++++++++++++++++++++++++ Outputs vary when I input keys( unicode text ) on keyboards. Myanmar Text Output IMG Padauk Output IMG Myanmar3 Output IMG Tharlon Output IMG Those fonts work well on Linux when opening text files with Text Editor application. My Question is how to unicode Myanmar texts on Java GUI. Do I need additional codes left to display well? Or Does Java still have errors? The fonts display well on Web Application (HTML, CSS) but I'm not sure about displaying on Java Web Application.

  • Is your Xcode4 stable?

    I have upgraded to Xcode4, and I'm experiencing unbelievable situation. Xcode4 crashes per 5 minute. Incredibly slow. Almost impossible to use. Maybe the problem is my hardware configuration. I'm using MacBook Air 3rd with 2GB ram with SSD. It was just fine with Xcode3, but now, it consumes all of memory and crashes too often. Does your Xcode4 stable? If so, please let me know what's your hardware configuration. I want to know whether this problem is caused by hardware configuration or not to decide buy a new mac.

  • How to organize a programming course?

    - by Bogdan Gavril
    I've been given the task to train our manual testers to become developers in test (write test automation!). some have basic programing knowledge (either dabbling in PHP or reading stuff) and some who have no experience. Note that I do have teaching experience, but with real students, not employees, and one concern is that they will not put extra hours except the 20% management gave them for the transition. Language to be taught and used: C# We have 8 hours per week to do this and should decide if they will make it in 2 months. I am thinking of a combined approach: use a manual such as Head First C# (although I'm not happy with the labs, they're mostly games and I don't want to add UI complexities) have them read from the manual do labs with them, solving more and more difficult problems and explain the theoretical stuff as well have them do a bigger project towards the end Some questions: do you have a better suggestion as far as manuals go? do you have a better aproach? Focus less on labs? what kind of assesments should I use and how often? should I let them do a bigger project (bank system or small game) and how much time should I invest in that? ideeas on labs? other resources ? Any other tips would be most welcomed! Thanks!

  • How can I become a better Javascript programmer?

    - by Elliot Bonneville
    I've been programming with Javascript for a few years now, and I guess I'm okay at it. I can solve pretty much any problem I come across, and while my solutions may not be that great, they work. However, I want to become a better Javascript programmer. I'd like to learn all the best-practices, tricks of the trade, things to avoid, and anything else I should know so that my code will be 100% optimized and as readable as possible. How do I do that? I realize this question has been loosely asked before here, but the OP was something of beginner. I want to get into the more advanced side of Javascript programming with this question. Is this possible or am I just being way too impatient? Do I just need to spend loads of time programming?

  • Hidden web standards behind Google "custom searchEngines"?

    - by Hoàng Long
    Today while playing with Google Chrome Omnibox, I notice a strange behavior. I guess there's some "hidden" web standard behind it, but can't figure it out. Here's how to reproduce: Go to http://edition.cnn.com/ Use the search function at the higher right corner, Search a random keyword, for example: "abc" Close the tabs. Open a new tab, type until Chrome reminds you about http://edition.cnn.com/, then press "Tab" The Omnibox now shows "Search CNN.com"! And when you type "abc" and press Enter, it uses the CNN search function to do the job, not Google! I also tried it for several different sites. To some it won't work. But to some sites, like CNN, vnexpress.net, it works after I use the search function of that site once. I also learnt about chrome://settings/searchEngines (type it in your chrome box and you will see), and learnt about you can add custom search engine in chrome. But the question is, why Chrome can realize the search URL automatically to some pages, and not others? It's not because some site subscribe to Google service, because I can do the same method for my site (http://ledohoanglong.wordpress.com), and I'm sure that there's no subscription. So I guess there's a method to "expose" the search function of a site, so that Google Chrome can catch it (after I call the search function of that site once, of courses). Does anyone know about how it works behind the scene?

  • How do you approach tutorials

    - by aurel
    Hi I get lots of interesting tutorials through feeds and sometimes I implement them step by step, other times I just read through them and note anything that I do not know. when ever I implement them I takes a long time - starting the project, typing the code (as I feel there is no point to copy and paste ), then going back and forth between browser and editing program All in all, I am interested to know how do you learn from the tutorials (I'm no where close to being an expert). Or if you don't use tutorials, is there any other way to learn? Thanks a lot

  • Is it wise to ask about design decisions made on a product during an interview?

    - by Desolate Planet
    I've been thinking about interview questions lately and I've been reflecting on bad interview experiences I've had in the past. One of particular note is where I had asked the interviewer why the team chose to use Spring over EJB3 in their product. The interviewer pretty much tore my face off, yelling "Because Spring is not the be all and end all of Java software development, do you want this job or not?". In response to this, I told him that this probably wasn't the job for me and I walked out the interview. He told me at the start of the interview that they had high stuff turnover, the product had gone from Modula 3 to Perl to Java then after asking him a technical question, he went in flames. It seemed obvious to me that he was toxic to the company with that kind of attitude. Question: Is it a good idea to probe on architectural choices taken in an interview? If not, why? From my own point of view, an interview is a two-way process. If the interviewers are testing me on my technical skills, I've got every right to ask them the same questions to 1) Figure out what their mindset and attitudes towards developing software solutions are and 2) To figure out if there are in line with how I would approach problems of that kind. It's very possible that the interviewer who got angry was a bad interviewer and forgot that an interview is a two-way process. If I was asked this, I would have simply said something along the lines of wanting to leverage the container more, but I certainly wouldn't have tried to put him in a state of meek capitulation. The interviewer in question was the lead developer in the team.
