  • Simple Java to XML example

    - by Tom Brito
    I've read a time ago about generate xml from Java using annotations, but I'm not finding a simple example now. If I want to make a xml file like: <x:element uid="asdf">value</x:element> from my java class: public class Element { private String uid = "asdf"; } Which annotations I should use to perform that? (I have a xml-schema, if this helps the generation)

  • TCP 3 way handshake

    - by Tom
    Hi, i'm just observing what NMAP is doing for the 3 ports it reports are open. I understand what a half-scan attack is, but what's happening doesnt make sense. NMAP is reporting ports 139 are 445 are open..... all fine. But when i look at the control bits, NMAP never sends RST once it has found out the port is open, It does this for port 135- but not 139 and 445. This is what happens: (I HAVE OMITTED THE victim's replies) Sends a 2 (SYN) Sends a 16 (ACK) Sends a 24 (ACK + PST) Sends a 16 (ACK) Sends a 17 (ACK + FIN) I dont get why NMAP doesnt 'RST' ports 139 and 445??

  • ASP.NET MVC Routes Login/Logout Problem

    - by Tom
    Hi Guys, Relatively new to ASP.NET MVC and little confused about how to do routing. My problem basically relates to "logged in" and "logged out routes" and having both as "/". i.e. I have home/index for logged out user which appears as "/" but this has got me confused as to how I can have home/home for logged in user and still have "/". I keep getting 127.0.0.1/home/home I could modify like 127.0.0.1/home - but I want it like "/". My confusion relates to the fact that the "/" [127.0.0.1/] is bound in the routes collection to home/index. Does anyone know how I can modify the routes dictionary (which will be binded ONCE at the start) so that the "/" can be shared for logged and non-logged users ? Thanks?

  • WYSIWYG-editor with "add custom html feature" and secure (validated) html output?

    - by Tom
    I've been looking into some of the WYSIWYG editors (TinyMCE, FCKEditor, etc.) and they all seem to offer a lot of options. However, one vital feature that seems to lack is a simple "add custom html" option which would allow the user to input any of these embed-snippets you find all around the web these days, for example a youtube video. This is different than a "edit html/source" feature as that requires actual knowledge of html and there is the risk of the user writing invalid code. Another issue that I couldn't find much about is the output html. How would I make sure that this output causes no security invulnerabilities? Even when the user has the ability to add his own html? So, basically, is there an open source WYSIWYG editor which covers these 2 features?

  • How do I add an SVN remote to a Git repository?

    - by Tom
    Hello! I recently used git-svn to clone an SVN repository, for the purposes of maintaining my own branch of an open-source project. I'm also working with others on this branch, so we use a shared Git repository to help with the collaboration. A colleague wishes to fetch new revisions from the original SVN repository. How might he accomplish this? I can simply run "git svn fetch" on my local machine, but seeing that my colleague has cloned from the shared Git repository, his local branch lacks the necessary SVN metadata for fetching. Thanks!

  • Anyone NOT using a Web Framework? Why?

    - by tom
    I'm well aware of the many reasons to use a web framework. I'm just wondering whether anyone out there is using absolutely no web framework whatsoever to develop their web projects. I would really love to know the reason(s) why you're not using a web framework. For the sake of this discussion, your programming language of choice does not matter. Some possibilities for discussion: You don't hide behind an ORM. You don't rely on any sort of templating system. You think MVC is a really nice TLA but lacks an essential vowel or two. No need for any additional javascript framework tomfoolery. You just write as much code as possible in your native programming language(s). Summary of reasons thus far: Language learning opportunities. Specific performance reasons (write-intensive transaction processing). Seeking more nuanced control over your data and applications (less abstraction). You're building your own framework! Prove to yourself that you can succeed (or fail) just like the big framework-building gurus. Integration issues with unpopular/legacy technologies (exotic databases or protocols come to mind). Big company, lots of code, no talent nor buy-in present to move to a web framework. Some frameworks really lock you in and cannot perpetually grow along with your needs. These few black sheep don't make it easy to jump outside of the framework, write some custom code, and easily jump back in. When you finally escape the asylum, you'll never look back.

  • Can somebody explain this remark in the MSDN CreateMutex() documentation about the bInitialOwner fla

    - by Tom Williams
    The MSDN CreatMutex() documentation (http://msdn.microsoft.com/en-us/library/ms682411%28VS.85%29.aspx) contains the following remark near the end: Two or more processes can call CreateMutex to create the same named mutex. The first process actually creates the mutex, and subsequent processes with sufficient access rights simply open a handle to the existing mutex. This enables multiple processes to get handles of the same mutex, while relieving the user of the responsibility of ensuring that the creating process is started first. When using this technique, you should set the bInitialOwner flag to FALSE; otherwise, it can be difficult to be certain which process has initial ownership. Can somebody explain the problem with using bInitialOwner = TRUE? Earlier in the same documentation it suggests a call to GetLastError() will allow you to determine whether a call to CreateMutext() created the mutex or just returned a new handle to an existing mutex: Return Value If the function succeeds, the return value is a handle to the newly created mutex object. If the function fails, the return value is NULL. To get extended error information, call GetLastError. If the mutex is a named mutex and the object existed before this function call, the return value is a handle to the existing object, GetLastError returns ERROR_ALREADY_EXISTS, bInitialOwner is ignored, and the calling thread is not granted ownership. However, if the caller has limited access rights, the function will fail with ERROR_ACCESS_DENIED and the caller should use the OpenMutex function.

  • Django 1.2 - Pb with a form in a template (WSGIRequest)

    Hi, I'm trying to display a form on a template, but I get a fantastic error : Caught AttributeError while rendering: 'WSGIRequest' object has no attribute 'get' The error is in this line : {% for field in form.visible_fields %} My view : def view_discussion(request, discussion_id): discussion = get_object_or_404(Discussion, id=discussion_id) form = BaseMessageForm(request) return render(request,'ulule/discussions/view_discussion.html', { 'discussion':discussion, 'form':form, }) My form : class BaseMessageForm(forms.Form): message_content = forms.CharField(widget=forms.HiddenInput()) My template : <form action="" method="post"> {% csrf_token %} {% for field in form.visible_fields %} <div class="fieldWrapper"> {% if forloop.first %} {% for hidden in form.hidden_fields %} {{ hidden }} {% endfor %} {% endif %} {{ field.errors }} {{ field.label_tag }}: {{ field }} </div> {% endfor %} <p><input type="submit" value="Send message" /></p> </form> Thanks a lot for your help !

  • Manipulate Excel workbooks programmatically

    - by Tom
    I have an Excel workbook that I want to use as a template. It has several worksheets setup, one that produces the pretty graphs and summarizes the numbers. Sheet 1 needs to be populated with data that is generated by another program. The data comes in a tab delimited file. Currently the user imports the tab delimited file into a new Workbook, selects all and copies. Then goes to the template and pastes the data into sheet1. This is a large amount of data, 269 columns and over 135,000 rows. It’s a cumbersome process and the users are not experienced Excel users. All they really want is the pretty graphs. I would like to add a step after the program that generates the data to programmatically automate the process the user currently must do manually. Can anyone suggest the best method/programming language that could accomplish this?

  • asp.net mvc script and style references

    - by tom
    I'm trying to include script and style references that will not break on deployment, however I can not even get the references to work locally. I have tried using Url.Content() and MVCContrib's <%=Html.ScriptInclude("")%>. My scripts are in a Scripts folder on the root of the site; my styles are in the usual Content/css/ folder. The scripts render like this: <script type="text/javascript" src="/Scripts/MicrosoftAjax.debug.js" ></script> This will not work in a view page in the Views folder. What am I doing wrong and what is the best way to handle this? I would have thought Url.Content() would at least work for styles but used in my master page, the link rendered <link href="/Content/css/Site.css rel="stylesheet" type="text/css" /> This does not work, because the Master Page is in a Shared folder, so what is really the way forward with this?

  • Django Aggregation Across Reverse Relationship

    - by Tom
    Given these two models: class Profile(models.Model): user = models.ForeignKey(User, unique=True, verbose_name=_('user')) about = models.TextField(_('about'), blank=True) zip = models.CharField(max_length=10, verbose_name='zip code', blank=True) website = models.URLField(_('website'), blank=True, verify_exists=False) class ProfileView(models.Model): profile = models.ForeignKey(Profile) viewer = models.ForeignKey(User, blank=True, null=True) created = models.DateTimeField(auto_now_add=True) I want to get all profiles sorted by total views. I can get a list of profile ids sorted by total views with: ProfileView.objects.values('profile').annotate(Count('profile')).order_by('-profile__count') But that's just a dictionary of profile ids, which means I then have to loop over it and put together a list of profile objects. Which is a number of additional queries and still doesn't result in a QuerySet. At that point, I might as well drop to raw SQL. Before I do, is there a way to do this from the Profile model? ProfileViews are related via a ForeignKey field, but it's not as though the Profile model knows that, so I'm not sure how to tie the two together. As an aside, I realize I could just store views as a property on the Profile model and that may turn out to be what I do here, but I'm still interested in learning how to better use the Aggregation functions.

  • How to dynamically change pagination urls in ExtJS?

    - by Tom Schaefer
    I have two data grids. The first auto-loads a list of items (json data store). OnCellClick the first grid fires a dynamically parametrized url and loads data into the second grid. It works fine, but the pagination of the second grid does not focus the new context. What shall I do to make the pagination work with the new url?

  • Defined outlets, connected them, they all returns (null)

    - by Tom
    Hi! I'm trying to play with a WebView. I made an outlet: IBOutlet UIWebView *browser; Defined it as a property: @property (nonatomic, retain) IBOutlet UIWebView *browser; Synthethized it: @synthesize browser; Finally, I connected it in Interface Builder, really it is. Then I try to do something with it i.e.: [browser loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://apple.com"]]]; Or also: Etape *etape = [[Etape alloc] init]; NSString *html = [etape generateHTMLforEtape:[current_etape objectAtIndex:0]]; [browser loadHTMLString:html baseURL:nil]; [etape release]; I get no errors, I tried to Build & Analyse, no notices or warnings or errors.. I've been searching for one whole day, please help me :/ Thanks a lot! EDIT: Here's screenshots of my connections for my WebView: EDIT: That is how I call the view: DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]]; dvController.workflow_id = parent_id; Etape *etape = [[Etape alloc] init]; dvController.etapes = [etape getEtapes:parent_id]; [etape release]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release];

  • SWIG_NewPointerObj and values always being nil

    - by Tom J Nowell
    I'm using SWIG to wrap C++ objects for use in lua, and Im trying to pass data to a method in my lua script, but it always comes out as 'nil' void CTestAI::UnitCreated(IUnit* unit){ lua_getglobal(L, "ai"); lua_getfield(L, -1, "UnitCreated"); swig_module_info *module = SWIG_GetModule( L ); swig_type_info *type = SWIG_TypeQueryModule( module, module, "IUnit *" ); SWIG_NewPointerObj(L,unit,type,0); lua_epcall(L, 1, 0); } Here is the lua code: function AI:UnitCreated(unit) if(unit == nil) then game:SendToConsole("I CAN HAS nil ?") else game:SendToConsole("I CAN HAS UNITS!!!?") end end unit is always nil. I have checked and in the C++ code, the unit pointer is never invalid/null I've also tried: void CTestAI::UnitCreated(IUnit* unit){ lua_getglobal(L, "ai"); lua_getfield(L, -1, "UnitCreated"); SWIG_NewPointerObj(L,unit,SWIGTYPE_p_IUnit,0); lua_epcall(L, 1, 0); } with identical results. Why is this failing? How do I fix it?

  • How to develop an english .com domain value rating algorithm?

    - by Tom
    I've been thinking about an algorithm that should rougly be able to guess the value of an english .com domain in most cases. For this to work I want to perform tests that consider the strengths and weaknesses of an english .com domain. A simple point based system is what I had in mind, where each domain property can be given a certain weight to factor it's importance in. I had these properties in mind: domain character length Eg. initially 20 points are added. If the domain has 4 or less characters, no points are substracted. For each extra character, one or more points are substracted on an exponential basis (the more characters, the higher the penalty). domain characters Eg. initially 20 points are added. If the domain is only alphabetic, no points are substracted. For each non-alhabetic character, X points are substracted (exponential increase again). domain name words Scans through a big offline english database, including non-formal speech, eg. words like "tweet" should be recognized. Question 1 : where can I get a modern list of english words for use in such application? Are these lists available for free? Are there lists like these with non-formal words? The more words are found per character, the more points are added. So, a domain with a lot of characters will still not get a lot of points. words hype-level I believe this is a tricky one, but this should be the cause to differentiate perfect but boring domains from perfect and interesting domains. For example, the following domain is probably not that valueable: www.peanutgalaxy.com The algorithm should identify that peanuts and galaxies are not very popular topics on the web. This is just an example. On the other side, a domain like www.shopdeals.com should ring a bell to the hype test, as shops and deals are quite popular on the web. My initial thought would be to see how often these keywords are references to on the web, preferably with some database. Question 2: is this logic flawed, or does this hype level test have merit? Question 3: are such "hype databases" available? Or is there anything else that could work offline? The problem with eg. a query to google is that it requires a lot of requests due to the many domains to be tested. domain name spelling mistakes Domains like "freemoneyz.com" etc. are generally (notice I am making a lot of assumptions in this post but that's necessary I believe) not valueable due to the spelling mistakes. Question 4: are there any offline APIs available to check for spelling mistakes, preferably in javascript or some database that I can use interact with myself. Or should a word list help here as well? use of consonants, vowels etc. A domain that is easy to pronounce (eg. Google) is usually much more valueable than one that is not (eg. Gkyld). Question 5: how does one test for such pronuncability? Do you check for consonants, vowels, etc.? What does a valueable domain have? Has there been any work in this field, where should I look? That is what I came up with, which leads me to my final two questions. Question 6: can you think of any more english .com domain strengths or weaknesses? Which? How would you implement these? Question 7: do you believe this idea has any merit or all, or am I too naive? Anything I should know, read or hear about? Suggestions/comments? Thanks!

  • Java Generic Type and Reflection

    - by Tom Tucker
    I have some tricky generic type problem involving reflection. Here's the code. public @interface MyConstraint { Class<? extends MyConstraintValidator<?>> validatedBy(); } public interface MyConstraintValidator<T extends Annotation> { void initialize(T annotation); } /** @param annotation is annotated with MyConstraint. */ public void run(Annotation annotation) { Class<? extends MyConstraintValidator<? extends Annotation>> validatorClass = annotation.annotationType().getAnnotation(MyConstraint.class).validatedBy(); validatorClass.newInstance().initialize(annotation) // will not compile! } The run() method above will not compile because of the following error. The method initialize(capture#10-of ? extends Annotation) in the type MyConstraintValidator<capture#10-of ? extends Annotation> is not applicable for the arguments (Annotation) If I remove the wild cards, then it compiles and works fine. What would be the propert way to declare the type parameter for the vairable validatorClass? Thanks.

  • UIWebView doesn't scroll to the bottom of the webpage loaded/created

    - by tom
    I have a UIWebView inside a normal UIViewController. The content of the UIWebView is programming/dynamically created in my program, and it could be very long (multiple table rows). Somehow, after loading, the page won't scroll more then one and half screen of content when swipe on the screen. Because of that I can only see the beginning few rows of data, but not the many others after them. Why is that?
