  • My father wants to learn PHP-MySQL to port his application. What I should do to help?

    - by adijiwa
    My father is a doctor/physician. About 15 years ago he started writing an application to handle his patient's medical records in his clinic at home. The app has the ability to input patient's medical records (obviously), search patients by some criteria, manage medicine stocks, output receipt to printer, and some more CRUDs. He wrote it in dBase III+. A few years later he migrated to FoxPro 2.6 for DOS and finally in a few more years he rewrote his app in Visual FoxPro 9. And now (actually two years ago) he wants to rewrite it in PHP, but he don't know how. The Visual FoxPro version of this app is still running and has no serious problem except sometimes it performs slowly. Usually there are 1-5 concurrent users. The binary and database files are shared via windows share. He did all the coding as a hobby and for free (it is for his own clinic after all). He also use this app in two other offices he managed. Some reasons of why he wants to rewrite in PHP-MySQL: He wants to learn Easier to deploy (?) Easier client setup, need only a browser What should I do to help my father? How should he start? I explored some options: I let my father learn PHP and MySQL (and HTML (and JavaScript?)) from scratch. I create/bundle framework. I'm thinking on bundling CodeIgniter and a web UI framework (any suggestion?) especially to reduce effort on writing presentation codes. What do you think? tl;dr My father (a doctor) wants to rewrite his Visual FoxPro app in PHP-MySQL. He knows very little of PHP and MySQL but he wants to learn. What should I do to help? How should he start? Some facts: My father is 50 years old. His first encounter with a PC is in early 1980s. It was IBM PC with Intel 8088. He knows BASIC. He taught me how to use DOS and how to program with BASIC. The other language he knows fairly well is dBase/FoxPro. I got my bachelor CS degree last year. I know the internals of my father's app because sometime he wants me to help him writing his app. Sorry for my english.

  • Just getting started in Spring and my preference is XML config over annotations. Correct or not?

    - by John Munsch
    After having read through some of the Spring docs my inclination is towards using a XML config file rather than annotations on the classes themselves. My reasoning is that by doing so you avoid tying your POJOs to a particular framework. Based on your experience with Spring, are there any advantages that XML configuration have over an annotation based configuration, and if not what are the disadvantages?

  • Where to get sounds for game development for kids [closed]

    - by at.
    I'm teaching kids to program using Ruby and the gaming framework Gosu/Chingu. For the sounds for their games I've been showing them http://www.bfxr.net/. It's decent, but the samples are limited and some of them are pretty cheap (check the explosion, it's like an explosion on a commodore 64 game). Is there an easy resource kids can get the sounds they want? I'm happy to pay some kind of educational license for it.

  • With a little effort you can &ldquo;SEMI&rdquo;-protect your C# assemblies with obfuscation.

    - by mbcrump
    This method will not protect your assemblies from a experienced hacker. Everyday we see new keygens, cracks, serials being released that contain ways around copy protection from small companies. This is a simple process that will make a lot of hackers quit because so many others use nothing. If you were a thief would you pick the house that has security signs and an alarm or one that has nothing? To so begin: Obfuscation is the concealment of meaning in communication, making it confusing and harder to interpret. Lets begin by looking at the cartoon below:     You are probably familiar with the term and probably ignored this like most programmers ignore user security. Today, I’m going to show you reflection and a way to obfuscate it. Please understand that I am aware of ways around this, but I believe some security is better than no security.  In this sample program below, the code appears exactly as it does in Visual Studio. When the program runs, you get either a true or false in a console window. Sample Program. using System; using System.Diagnostics; using System.Linq;   namespace ObfuscateMe {     class Program     {                static void Main(string[] args)         {               Console.WriteLine(IsProcessOpen("notepad")); //Returns a True or False depending if you have notepad running.             Console.ReadLine();         }             public static bool IsProcessOpen(string name)         {             return Process.GetProcesses().Any(clsProcess => clsProcess.ProcessName.Contains(name));         }     } }   Pretend, that this is a commercial application. The hacker will only have the executable and maybe a few config files, etc. After reviewing the executable, he can determine if it was produced in .NET by examing the file in ILDASM or Redgate’s Reflector. We are going to examine the file using RedGate’s Reflector. Upon launch, we simply drag/drop the exe over to the application. We have the following for the Main method:   and for the IsProcessOpen method:     Without any other knowledge as to how this works, the hacker could export the exe and get vs project build or copy this code in and our application would run. Using Reflector output. using System; using System.Diagnostics; using System.Linq;   namespace ObfuscateMe {     class Program     {                static void Main(string[] args)         {               Console.WriteLine(IsProcessOpen("notepad"));             Console.ReadLine();         }             public static bool IsProcessOpen(string name)         {             return Process.GetProcesses().Any<Process>(delegate(Process clsProcess)             {                 return clsProcess.ProcessName.Contains(name);             });         }       } } The code is not identical, but returns the same value. At this point, with a little bit of effort you could prevent the hacker from reverse engineering your code so quickly by using Eazfuscator.NET. Eazfuscator.NET is just one of many programs built for this. Visual Studio ships with a community version of Dotfoscutor. So download and load Eazfuscator.NET and drag/drop your exectuable/project into the window. It will work for a few minutes depending if you have a quad-core or not. After it finishes, open the executable in RedGate Reflector and you will get the following: Main After Obfuscation IsProcessOpen Method after obfuscation: As you can see with the jumbled characters, it is not as easy as the first example. I am aware of methods around this, but it takes more effort and unless the hacker is up for the challenge, they will just pick another program. This is also helpful if you are a consultant and make clients pay a yearly license fee. This would prevent the average software developer from jumping into your security routine after you have left. I hope this article helped someone. If you have any feedback, please leave it in the comments below.

  • Combobox binding with different types

    - by George Evjen
    Binding to comboboxes in Silverlight has been an adventure the past couple of days. In our framework at ArchitectNow we use LookupGroups and LookupValues. In our database we would have a LookupGroup of NBA Teams for example. The group would be called NBATeams, we get the LookupGroupID and then get the values from the LookupValues table. So we would end up with a list of all 30+ teams. Our lookup values entity has a display text(string), value(string), IsActive and some other fields. With our applications we load all this information into the system when the user is logging in or right after they login. So in cache we have a list of groups and values that we can get at whenever we want to. We get this information in our framework simply by creating an observable collection of type LookupValue. To get a list of these values into our property all we have to do is. var NBATeams = AppContext.Current.LookupSerivce.GetLookupValues(“NBATeams”); Our combobox then is bound like this. (We use telerik components in most if not all our projects) <telerik:RadComboBox ItemsSource="{Binding NBATeams}”></telerik:RadComboBox> This should give you a list in your combobox. We also set up another property in our ViewModel that is a just single object of NBATeams  - “SelectedNBATeam” Our selectedItem in our combobox would look like, we would set this to a two way binding since we are sending data back. SelectedItem={Binding SelectedNBATeam, mode=TwoWay}” This is all pretty straight forward and we use this pattern throughout all our applications. What do you do though when you have a combobox in a ItemsControl or ListBox? Here we have a list of NBA Teams that are a string that are being brought back from the database. We cant have the selected item be our LookupValue because the data is a string and its being bound in an ItemsControl. In the example above we would just have the combobox in a form. Here though we have it in a ItemsControl, where there is no selected item from the initial ItemsSource. In order to get the selected item to be displayed in the combobox you have to convert the LookupValue to a string. Then instead of using SelectedItem in the combobox use SelectedValue. To convert the LookupValue we do this. Create an observable collection of strings public ObservableCollection<string> NBATeams { get; set;} Then convert your lookups to strings var NBATeams = new ObservableCollection<string>(AppContext.Current.LookupService.GetLookupValues(“NBATeams”).Select(x => x.DisplayText)); This will give us a list of strings and our selected value should be bound to the NBATeams property in our ItemsSource in our ItemsControl. SelectedValue={Binding NBATeam, mode=TwoWay}”

  • JavaOne 2012: Camel, Twitter, Coherence, Wicket and GlassFish

    - by Bruno.Borges
    Before joining Oracle as Product Manager for WebLogic and GlassFish for Latin America, at the beggining of this year I proposed two talks to JavaOne USA that I had been presenting in Brazil for quite a while. One of them I presented last year at ApacheCon in Vancouver, Canada as well in JavaOne Brazil. In June I got the news that they were accepted as Alternate Sessions. Surprisingly enough, few weeks later and at the same time I joined Oracle, I received the news that they were officially accepted and put on schedule. Tomorrow I'll be flying to San Francisco, to my first JavaOne in the United States, and I wanted to share with you what I'm going to present there. My two sessions are these ones: Wed, 10/03, 4:30pm - CON2989 Leverage Enterprise Integration Patterns with Apache Camel and TwitterOn this one, you will be introducted to the Apache Camel framework that I had been talking about in Brazil at conferences, before joining Oracle, and to a component I contributed to integrate with Twitter. Also, you will have a preview of a new component I've been working on to integrate Camel with the Oracle Coherence distributed cache. Thu, 10/04, 3:30pm - CON3395 How Scala, Wicket, and Java EE Can Improve Web DevelopmentThis one I've been working on for quite a while. It was based on an idea to have an architecture that could be as agile as frameworks and technologies such as Ruby on Rails, PHP or Python, for rapid web development. You will be introduced to the Apache Wicket framework, another Apache project I enjoy working with and gave lots of talks at Brazilian conferences, including JavaOne Brazil, JustJava, QCon SP, and The Developers Conference. You will also be introduced to the Scala language and how to create nice DSLs to boost productiveness. And last but not least, the Java EE 6 platform, that offers an awesome improvement from previous versions with its CDI, JPA, EJB3 and JAX-RS features for web development. Other events I will be participating during my stay in SF: Geeks Bike Ride GlassFish Community Event GlassFish and Friends Party    If you have any other event to suggest, please do suggest! It's my first JavaOne and I'm really looking forward to enjoying everything. See you guys in a few days!!

  • Career advice: stay with PHP or start a new career in something else ( .Net?)

    - by Christian P
    I'm planning on moving to NY in 6-12 months tops, so I'm forced to find a new job. When I'm planing to start my life in another city it's also probably a good time to think about career changes. I've found a lot of different opinions about PHP vs .Net vs Java and this is not topic here. I don't want to start a new fight about which language is better. Knowing programming language is not the most important thing for being a software developer. To be a really good developer you need to know OOP, design patterns, testing... and language is just a tool to make things happen. So back to my question. I have mixed experience in IT - 1 year as an IT support guy (Windows administration and support), around 2 years of experience in embedded programming (VB.Net 2005) and for the last 2 years I'm working with PHP/MySQL. I have worked with Magento web shop, assisted in some projects in Symfony, modified few Drupal sites. My main concerns are following: Do I continue to improve my skills in PHP e.g. to start learning some major PHP framework like Zend, Symfony maybe get some PHP certification. Or do I start learning .NET or Java. I'm more familiar to .NET so I'll probably choose it if choice falls between .NET and Java ( or you could convince me to choose Java :). Career-wise, I don't know what is the best choice. Learning new framework and language is more time consuming then improving my existing skills in PHP. But with .NET you have a lot of possibilities (Windows 7 Phone development, Silverlight, WPF) and possibly bigger chances to find better jobs. PHP jobs are less payed then .NET, at least, according to my researches (correct me if I'm wrong). But if I start now with .NET I'm just a beginner and my salary will be low. I need at least 2+ years of experience in some language to even try to find some job that is paying higher than $50-60k in NY. My main goal in next 2-3 years is to try to find a job in a $60-80k category. Don't get me wrong, I'm not just chasing money, but money is an important factor when you're trying to start a family. I'm 27 years old and I feel that there isn't a lot of room for wrong decisions regarding my career, so any advice will be very welcome. Update Thank you all for spending time to help me with my problem. All of the answers and comments have been very helpful. I have decided to stick with PHP but also to learn C# and Silverlight 4. We'll see where the life will take me.

    - by Conor
    What implementation problems has the industry claimed to have solved many times, but are still soaking up all of your time? Examples: Cross platform GUI - mobile devices have blown this issue wide open. OO to RDBMS mapping - how do I map this attribute to that field in that database using that framework. You get the idea. Interface definitions - ..., CORBA, COM, EJB, WSDL, ..., etc Can you think of any others?

  • Monitoring GWT Website

    - by Raf
    We currently monitor our webapps using curl. More and more of our webapps use the GWT framework, which uses tons of javascript, and we can't rely on our curl system to monitor anymore. Therefore, we search the right tool to monitor, but it seems difficult to find a crawler which is light (no Selenium please) but handles javascript correctly. PS : we host our webapps as well as the probes, we don't want any Internet monitoring service.

  • 2D mouse coordinates from 3d object projection

    - by user17753
    Not entirely certain of the nomenclature here -- basically, after placing a model in world coordinates and setting up a 3D camera to look at it the model has been projected onto the screen in a 2D fashion. What I'd like to do is determine if the mouse is inside the projected view of the model. Is there a way to "unproject" in the XNA framework? Or what is this process called as, so that I can better search for it?

It seems I am stuck back in the 2.0 days of the framework and language, so what should I do to make use of all latest features? It is worth pointing out this but rather than just what changes have been made, what small programs could I implement that would teach me a lot of the new features?

  • JEP 124: Enhance the Certificate Revocation-Checking API

    - by smullan
    Revocation checking is the mechanism to determine the revocation status of a certificate. If it is revoked, it is considered invalid and should not be used. Currently as of JDK 7, the PKIX implementation of java.security.cert.CertPathValidator  includes a revocation checking implementation that supports both OCSP and CRLs, the two main methods of checking revocation. However, there are very few options that allow you to configure the behavior. You can always implement your own revocation checker, but that's a lot of work. JEP 124 (Enhance the Certificate Revocation-Checking API) is one of the 11 new security features in JDK 8. This feature enhances the java.security.cert API to support various revocation settings such as best-effort checking, end-entity certificate checking, and mechanism-specific options and parameters. Let's describe each of these in more detail and show some examples. The features are provided through a new class named PKIXRevocationChecker. A PKIXRevocationChecker instance is returned by a PKIX CertPathValidator as follows: CertPathValidator cpv = CertPathValidator.getInstance("PKIX"); PKIXRevocationChecker prc = (PKIXRevocationChecker)cpv.getRevocationChecker(); You can now set various revocation options by calling different methods of the returned PKIXRevocationChecker object. For example, the best-effort option (called soft-fail) allows the revocation check to succeed if the status cannot be obtained due to a network connection failure or an overloaded server. It is enabled as follows: prc.setOptions(Enum.setOf(Option.SOFT_FAIL)); When the SOFT_FAIL option is specified, you can still obtain any exceptions that may have been thrown due to network issues. This can be useful if you want to log this information or treat it as a warning. You can obtain these exceptions by calling the getSoftFailExceptions method: List<CertPathValidatorException> exceptions = prc.getSoftFailExceptions(); Another new option called ONLY_END_ENTITY allows you to only check the revocation status of the end-entity certificate. This can improve performance, but you should be careful using this option, as the revocation status of CA certificates will not be checked. To set more than one option, simply specify them together, for example: prc.setOptions(Enum.setOf(Option.SOFT_FAIL, Option.ONLY_END_ENTITY)); By default, PKIXRevocationChecker will try to check the revocation status of a certificate using OCSP first, and then CRLs as a fallback. However, you can switch the order using the PREFER_CRLS option, or disable the fallback altogether using the NO_FALLBACK option. For example, here is how you would only use CRLs to check the revocation status: prc.setOptions(Enum.setOf(Option.PREFER_CRLS, Option.NO_FALLBACK)); There are also a number of other useful methods which allow you to specify various options such as the OCSP responder URI, the trusted OCSP responder certificate, and OCSP request extensions. However, one of the most useful features is the ability to specify a cached OCSP response with the setOCSPResponse method. This can be quite useful if the OCSPResponse has already been obtained, for example in a protocol that uses OCSP stapling. After you have set all of your preferred options, you must add the PKIXRevocationChecker to your PKIXParameters object as one of your custom CertPathCheckers before you validate the certificate chain, as follows: PKIXParameters params = new PKIXParameters(keystore); params.addCertPathChecker(prc); CertPathValidatorResult result = cpv.validate(path, params); Early access binaries of JDK 8 can be downloaded from http://jdk8.java.net/download.html
