Do WHOIS listings get spammed?

- by Claudiu

I'm thinking of registering a domain name. Is there any danger putting my real info on there? Do they get spammed by phone spam, snail mail spam, or email spam?

http in web browser address bar

If we type a domain name in web browser address bar, How it will be add default ? Ex. If i type linkedin.com in web browser address bar, How it will be add www and http:// ----- http://www.linkedin.com/ ....... If i didn't mention ftp also it will add automatically add ftp://...... Based on what concept, it will work. I know it basic and simple question. But please tell about it as clear as possible

Other then DDNS, can a fake primary DNS server break anything else?

- by Nimmy Lebby

I am aware that the primary server listed in SOA record has to be valid for DDNS to work. Is anyone aware of any other application that uses the SOA listed primary DNS server in one way or the other? By a fake primary server I mean either: Inaccessible by anything else other than secondary servers (this is called hidden primary correct? unsure). A completely fake domain name like dig +short soa spamhaus.org

Some questions regarding Hostname

- by user481913

I just bought a new VPS hosting plan and i have a few questions. Hope someone here can clear the doubts for me. 1) Is it necessary to have a real domain for a vps hostname? I suppose i can just use a non-real domain like anydomain.com and something like 'server' for the computer name. Therefore i'll end up with something like server.anydomain.com as the vps's hostname. I want to do this for the sake of putting in a hostname to configure the vps to get it going . So, since this non-real domain name does not need to be publicly accessible i don't need to register or own it and instead access the server by the ip address. Is that correct? But i suppose that this also depends upon if my web host allows that? 2)I would also like to run some real sites with real domain names on this vps, so can i just configure the zone file on the primary nameserver and make entries for these domains and point an A record at the Vps's IP to make them publicly accessible over the internet? For example for my 1st domain i could make an entry like this: $TTL 86400 mydomain1.com. IN SOA ns1.mywebhost.com. \ admin.mydomain1.com. ( 2004011522 ; Serial no., based on date 21600 ; Refresh after 6 hours 3600 ; Retry after 1 hour 604800 ; Expire after 7 days 3600 ; Minimum TTL of 1 hour ) server IN A 200._._._ ns1.mywebhost.com. IN A 216._._._ ns2.mywebhost.com. IN A 205._._._ @ IN NS ns1.mywebhost.com. @ IN NS ns2.mywebhost.com. @ IN MX 10 server www IN CNAME server server IN CNAME @ (so this particular line tells the nameserver to point the url mydomain1.com to server.anydomain.com at the particular ip addresss in the A record.... is that right?) Similarly for my 2nd domain i could have a similar entry : $TTL 86400 mydomain2.com. IN SOA ns1.mywebhost.com. \ admin.mydomain2.com. (..... ............................so on........ ......................................... ......................................... ......................................... ......................................... ......................................... Is that correct? 3) Suppose for my vps hostname, i ignorantly chose a domain that someone else alreadys owns , however i think that it won't affect the public accessibility of the real domain or website since only the real owner of the domain has the rights to provide for the nameservers addresses in the TLD registeries through his Domian Registerar? Is that correct? 4)Can i change my vps's hostname later? Would this create any complications?

Trouble registering punycode domain!

- by chaz

Not sure if any of you have experience with this, but I am trying to include the anchor (?) in my domain name (using the appropriate punycode to allow it) but upon registering it I encounter the error that the symbol is not supported by the language I have chosen. Does anyone know what language would support this if I were to continue or even how I would go about doing so or if i can even do so. Thanks

Help with restoring expired domain as quick as possible

- by Pasta

My domain name expired today (owing to missing credit card info, etc) and it is really important as the company has about 50 users who cannot access emails, website unreachable, etc. I have requested UKReg to bring the domains backup and running but they will take about 24 hours to get it back up and running. Is there anything that I can do to return the service back to normal quicker?

How to reference or connect a variable to another class without stack overflow?

- by SystemNetworks

I really need to re-arrange all my functions. I created a class. All my var, booleans, int, doubles and other things. I created every new variable so they can reference it and so they don't have an error. If your asking why I never just reference my main class vars to my sub-class becuase it will give me stack overflow! When in my main class i link my sub-class. subClass s = new subClass(); Then I reference my fake variable to my real variable for example: This is my sub-class variable(I call it fake) public int x = 0; In my main class, I put it like this: s.x = x; The problem is, it does not work! Maybe this is not the right place but I cant ask any questions on stack overflow because they banned me. If I connect my main class and connect my sub-class it will give me stack overflow. How do I stop it?

Unable to determine the provider name for connection of type 'System.Data.SqlServerCe.SqlCeConnectio

- by Hobbes1312

Hi, i am using the Ado.Net Entity Framework with Code Only (Tutorial at: ADO.NET team blog) and i want to be as much database independent as possible. In my first approach i just want to go for Sql Express and Sql Compact databases. With Sql Express everthing works fine but with Sql Compact i get the exception mentioned in my question. Does anybody knows if it is possible to connect to Sql Compact with the Code Only approach? (with a generated .edmx file for a Sql Compact database everthing works fine, but i want to use code only!) Here is some code: My Class which is building the DataContext: public class DataContextBuilder : IDataContextBuilder { private readonly DbProviderFactory _factory; public DataContextBuilder(DbProviderFactory factory) { _factory = factory; } #region Implementation of IDataContextBuilder public IDataContext CreateDataContext(string connectionString) { var builder = new ContextBuilder<DataContext>(); RegisterConfiguration(builder); var connection = _factory.CreateConnection(); connection.ConnectionString = connectionString; var ctx = builder.Create(connection); return ctx; } #endregion private void RegisterConfiguration(ContextBuilder<DataContext> builder) { builder.Configurations.Add(new PersonConfiguration()); } } The line var ctx = builder.Create(connection); is throwing the exception. The IDataContext is just a simple Interface for the ObjectContext: public interface IDataContext { int SaveChanges(); IObjectSet<Person> PersonSet { get; } } My connection string is configured in the app.config: <connectionStrings> <add name="CompactConnection" connectionString="|DataDirectory|\Test.sdf" providerName="System.Data.SqlServerCe.3.5" /> </connectionStrings> And the build action is started with var cn = ConfigurationManager.ConnectionStrings["CompactConnection"]; var factory = DbProviderFactories.GetFactory(cn.ProviderName); var builder = new DataContextBuilder(factory); var context = builder.CreateDataContext(cn.ConnectionString);

Grouping every 3 items in xslt 1.0

- by Piotr Czapla

I'm having troubles to figure out a way to group items xslt 1.0. I have a source xml similar to the one below: <client name="client A"> <project name = "project A1"/> <project name = "project A2"/> <project name = "project A3"/> <project name = "project A4"/> </client> <client name="client B"> <project name = "project B1"/> <project name = "project B2"/> </client> <client name="client C"> <project name = "project C1"/> <project name = "project C2"/> <project name = "project C3"/> </client> I'd like to select all projects, sort them and then group every 3 project in one boundle as in the example below: <boundle> <project name="project A1"> <project name="project A2"> <project name="project A3"> </boundle> <boundle> <project name="project A4"> <project name="project B1"> <project name="project B2"> </boundle> <boundle> <project name="project C1"> <project name="project C2"> <project name="project C3"> </boundle> Currently to do so I'm using to open a boundle tag and close it later. Can you think about any better solution?

function to get the file name of an URL

- by user262325

Hello everyone I have some source code to get the file name of an url for example: http://www.google.com/a.pdf I hope to get a.pdf because the way to join 2 NSStrings I can get is 'appendString' which only for adding a string at right side, so I planned to check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop the checking, return string fdp.a , after that I change fdp.a to a.pdf source codes are below -(NSMutableString *) getSubStringAfterH : originalString:(NSString *)s0 { NSInteger i,l; l=[s0 length]; NSMutableString *h=[[NSMutableString alloc] init]; NSMutableString *ttt=[[NSMutableString alloc] init ]; for(i=l-1;i>=0;i--) //check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop { ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; if([ttt isEqualToString:@"/"]) { break; } else { [h appendString:ttt]; } } [ttt release]; //below are to change the sequence of char in h // txt.edcba -> abcde.txt NSMutableString *h1=[[[NSMutableString alloc] initWithFormat:@""] autorelease]; for (i=[h length]-1;i>=0;i--) { NSMutableString *t1=[[NSMutableString alloc] init ]; t1=[h substringWithRange:NSMakeRange(i, 1)]; [h1 appendString:t1]; [t1 release]; } [h release]; return h1; } h1 can reuturn the coorect string a.pdf, but if it returns to the codes where it was called, after a while system reports 'double free * set a breakpoint in malloc_error_break to debug' I checked a long time and foudn that if I removed the code ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; everything will be Ok (of course getSubStringAfterH can not returns the corrent result I expected.), no error reported. I try to fix the bug a few hours, but still no clue. Welcome any comment Thanks interdev

Resharper Live Template Macro that changes variable name upon exit

- by Luhmann

I would like to create a Resharper Live Template that changes all spaces to underscores ind my "fact" Live template variable $testname$: <Fact()> _ Public Sub $testnames$() ' Arrange $END$ ' Act ' Assert End Sub I have this: [Macro("applyRegex", ShortDescription = "Run on {#0:variable}", LongDescription = "")] class ApplyRegexMacro : IMacro { public string EvaluateQuickResult(IHotspotContext context, IList<string> arguments) { return Regex.Replace(arguments[0], " ", "_", RegexOptions.IgnoreCase); } public HotspotItems GetLookupItems(IHotspotContext context, IList<string> arguments) { return null; } public string GetPlaceholder() { return "placeholder"; } public bool HandleExpansion(IHotspotContext context, IList<string> arguments) { return false; } public ParameterInfo[] Parameters { get { return new[] { new ParameterInfo(ParameterType.String), new ParameterInfo(ParameterType.String), new ParameterInfo(ParameterType.VariableReference) }; } } } But this only runs when i press tab. I want the macro to run after I tab out of $testname$. I want to be able to just write the test name in a single line of text with spaces, and then the Macro turns all the spaces into underscores. Is this possible?

Test Ruby-on-Rails controller with RSpec and different route name

- by jhwist

I have a Rails model named Xpmodule with a corresponding controller XpmoduleController. class XpmoduleController < ApplicationController def index @xpmodule = Xpmodule.find(params[:module_id]) end def subscribe flash[:notice] = "You are now subscribed to #{params[:subscription][:title]}" redirect_to :action => :index end end The original intent was to name the model Module which for obvious reasons doesn't work. However I still want to have the URLs look like /module/4711/ therefore I added this to my routes.rb: map.connect '/module/:module_id', :controller => 'xpmodule', :action => 'index' map.connect '/module/:module_id/subscribe', :controller => 'xpmodule', :action => 'subscribe' Now I want to test this controller with Rspec: describe XpmoduleController do fixtures :xpmodules context "index" do it "should assign the current xpmodule" do xpm = mock_model(Xpmodule) Xpmodule.should_receive(:find).and_return(xpm) get "index" assigns[:xpmodule].should be_an_instance_of(Xpmodule) end end end for which I get No route matches {:action=>"index", :controller=>"xpmodule"}. Which of course is sort-of right, but I don't want to add this route just for testing purposes. Is there a way to tell Rspec to call a different URL in get?

Hello guys, I'm having troubles with the logic and would apprecite any help/tips. I have <Deposits> elements and <Receipts> elements. However there isn't any identification what receipt was paid toward what deposit. I am trying to update the <Deposits> elements with the following attributes: @DueAmont - the amount that is still due to pay @Status - whether it's paid, outstanding (partly paid) or due @ReceiptDate - the latest receipt's date that was paid towards this deposit Every deposit could be paid with one or more receipts. It also could happen, that 1 receipt could cover one or more deposits. For example. If there are 3 deposits: 500 100 450 That are paid with the following receipts: 200 100 250 I want to get the following info: Deposit 1 is fully paid (status=paid, dueAmount=0, receiptNum=3. Deposit 2 is partly paid (status=outstanding, dueAmount=50, receiptNum=3. Deposit 3 is not paid (status=due, dueAmount=450, receiptNum=NAN.

Java Generics name clash, method not correctly overriden

- by Shervin

Hi. I have seen different questions regarding this, but I still find this topic to be very confusing. All I want to do, is have an abstract class that implements an interface, and have a class extending this abstract class so that the hard class needs to implement getKommune() and setKommune(Kommune kommune), but not the other method, because that is in the abstract class. I have the following interface. public interface KommuneFilter { <E extends AbstractKommune<?>> void addKommuneFromCurrentUser(E e); Kommune getKommune(); void setKommune(Kommune kommune); } And this Abstract class public abstract class AbstractKommune<E extends AbstractKommune<?>> implements KommuneFilter { @PrePersist void addKommuneFromCurrentUser(E e) { } } And I want to use it like this public class Person extends AbstractKommune<Person> { private Kommune kommune; public void setKommune(Kommune kommune) {this.kommune=kommune;} public Kommune getKommune() {return kommune;} } However, I get Name clash: The method of has the same erasure of type but does not override it Why isn't it correctly overriden?

HtmlHelper Getting the route name

- by Simon G

Hi, I've created a html helper that adds a css class property to a li item if the user is on the current page. The helper looks like this: public static string MenuItem( this HtmlHelper helper, string linkText, string actionName, string controllerName, object routeValues, object htmlAttributes ) { string currentControllerName = ( string )helper.ViewContext.RouteData.Values["controller"]; string currentActionName = ( string )helper.ViewContext.RouteData.Values["action"]; var builder = new TagBuilder( "li" ); // Add selected class if ( currentControllerName.Equals( controllerName, StringComparison.CurrentCultureIgnoreCase ) && currentActionName.Equals( actionName, StringComparison.CurrentCultureIgnoreCase ) ) builder.AddCssClass( "active" ); // Add link builder.InnerHtml = helper.ActionLink( linkText, actionName, controllerName, routeValues, htmlAttributes ); // Render Tag Builder return builder.ToString( TagRenderMode.Normal ); } I want to expand this class so I can pass a route name to the helper and if the user is on that route then it adds the css class to the li item. However I'm having difficulty finding the route the user is on. Is this possible? The code I have so far is: public static string MenuItem( this HtmlHelper helper, string linkText, string routeName, object routeValues, object htmlAttributes ) { string currentControllerName = ( string )helper.ViewContext.RouteData.Values["controller"]; string currentActionName = ( string )helper.ViewContext.RouteData.Values["action"]; var builder = new TagBuilder( "li" ); // Add selected class // Some code for here // if ( routeName == currentRoute ) AddCssClass; // Add link builder.InnerHtml = helper.RouteLink( linkText, routeName, routeValues, htmlAttributes ); // Render Tag Builder return builder.ToString( TagRenderMode.Normal ); } BTW I'm using MVC 1.0.

Reference a Map by name within Velocity Template

Pretty sure there is an easy answer to this, but just can't find the right VTL syntax. In my context I'm passing a Map which contains other Maps. I'd like to reference these inner maps by name and assign them within my template. The inner maps are constructed by different parts of the app, and then added to the context by way of example public static void main( String[] args ) throws Exception { VelocityEngine ve = new VelocityEngine(); ve.init(); Template t = ve.getTemplate( "test.vm" ); VelocityContext context = new VelocityContext(); Map<String,Map<String,String>> messageData = new HashMap<String, Map<String,String>>(); Map<String,String> data_map = new HashMap<String,String>(); data_map.put("data_1","1234"); data_map.put("a_date", "31-Dec-2009"); messageData.put("inner_map", data_map); context.put("msgData", messageData); StringWriter writer = new StringWriter(); t.merge( context, writer ); System.out.println( writer.toString() ); } Template - test.vm #set ($in_map = $msgData.get($inner_map) ) data: $in_map.data_1 $in_map.a_date

[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified - works

- by Matt

Hello, I am developing a java app (with odbc bridge - forgive me - the only paradox driver I have been able to obtain is the microsoft odbc driver) - which works fine while in eclipse, (and netbeans) - connecting and obtaining data from an ancient paradox 5.x database. So long as it is run from inside my IDE - it compiles and runs flawlessly. When I export it to a runable jar, suddenly [code][Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified[/code] occurs. The jar is being run on the same box as my developing IDE - so I am confused about the cause. It is being run via console from a user account, as per the IDE. My connection string is "jdbc:odbc:Driver={Microsoft Paradox Driver (*.db )};DriverID=538; Fil=Paradox 5.X; DefaultDir=C:\paradox\database\location\" - obtained from connectionstrings.com - and as mentioned before, working fine while run from the IDE. The above seems to 'magically' create its own connection, avoiding the setup of a dsn - I am unsure quite how it does - but it works. The only other thing I can think that might be pertinent is that my PC is a 64bit o/s (windows server 2008). Please help, any suggestions or comments will be greatly appreciated. Thanks, Matt

c# Deserializing an element based on it's parent node's name

- by daveharnett

The XML I'm working with has the following structure: <fixture_statistics> <home_player_1 id="2306143" teamid="2"> <element_1>Some Data</element_1> <element_2>Some Data</element_2> </home_player_1> <home_player_2 id="2306144" teamid="2"> <element_1>Some Data</element_1> <element_2>Some Data</element_2> </home_player_2> </fixture_statistics> Now the code to deserialize it would normally look like this: [XmlRootAttribute("fixture_statistics", Namespace = "", IsNullable = false)] public class FixtureRoot { [XmlElement("home_player_1")] [XmlElement("home_player_2")] public List<FixtureStats> fixtures { get; set; } } public class FixtureStats { public string element_1; [XMLElement("element_2")] public string elementTwo; } Here's the question: I'd like the FixtureStats class to have a 'position' property which corrosponds to it's parent's element name (so the FixtureStat object corrosponding to home_player_1 would have position=1). Can this be done with the built-in serialization atrributes? If it's not possible, what's the cleanest workaround? Bear in mind that each document will have about 50 player elements, each with about 50 'child' data elements.

Verifying existence of name and password in NSUserDefaults to Skip a login/Screen

I have a Tabbar/Tableview App that modally loads a Login/Signup view when the app loads, I have set up a Root.plist in a settings bundle for the name and password and have successfully retrieved the items. I want to be able to do two things: 1) Do a test to see if the NSUserDefault Strings are empty and if so load the Login/Signup view. 2) If the strings are available then use the string contents to login to my Webservice.

Having a Python package install itself under a different name

- by cool-RR

I'm developing a package called garlicsim. (Website.) The package is intended for Python 2.X, but I am also offerring Python 3 support on a different fork called garlicsim_py3.(1) So both of these packages live side by side on PyPI, and Python 3 users install garlicsim_py3, and Python 2 users install garlicsim. The problem is: When third party modules want to use garlicsim, they should have one package name to refer to, not two. Sure, they can do something like this: try: import garlicsim except ImportError: import garlicsim_py3 as garlicsim But I would prefer not to make the developers of these modules do this. Is there a way that garlicsim_py3 will install itself under the alias garlicsim? What I want is for a Python 3 user to be able to import garlicsim and refer to the module all the time as garlicsim, but that it will really be garlicsim_py3. I know that the Distribute project does something like this: They make it so you can import setuptools and it will be redirected into their code. I have no idea how they do it. Any ideas? (1) I've reached the decision to support Python 3 on a fork instead of in the same code base; It's important for me that the code base will be clean, and I would really not want to introduce compatibilty hacks.

But I run "test" as root since "test" permission is -rwsr-xr-x Question: Why did result come out like this? is the src.tar.gz group should be "src"? Output: Error: my group: src Error: src.tar.gz group is root test.c #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <string.h> #include <sys/types.h> #include <sys/stat.h> #include <grp.h> void main(int ac, char **args) { const char *ERR_MSG_FORMAT = "%s: %s %s.\n"; char *ptr_source_file = "src.tar.gz"; struct stat src_stat; gid_t src_gid, my_gid; int i = stat(ptr_source_file, &src_stat); my_gid = getgid(); struct group *cur_gr = getgrgid(my_gid); fprintf(stderr, ERR_MSG_FORMAT, "Error", "my group: ", cur_gr->gr_name); src_gid = src_stat.st_gid; struct group *src_gr = getgrgid(src_gid); fprintf(stderr, ERR_MSG_FORMAT, "Error","src.tar.gz group is ", src_gr->gr_name); }

"ImportError: cannot import name Exchange" when using Celery w/ Kombu installed

- by alukach

I'm trying to create a Celery worker node on an Amazon EC2 Windows2008 R2 instance. Due to a plugin we require for another Python module, we are required to user Python3. I've installed Python3.2 and necessary modules and run Celery, but for some reason it states that it can't import Exchange and Queue from Kombu, despite the face that Kombu is installed and can be imported by python. Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation. All rights reserved. C:\Users\Administrator>celery Traceback (most recent call last): File "C:\Python32\Scripts\celery-script.py", line 9, in <module> load_entry_point('celery==3.0.11', 'console_scripts', 'celery')() File "C:\Python32\lib\site-packages\celery\__main__.py", line 13, in main from celery.bin.celery import main File "C:\Python32\lib\site-packages\celery\bin\celery.py", line 21, in <module> from celery.utils import term File "C:\Python32\lib\site-packages\celery\utils\__init__.py", line 22, in <module> from kombu import Exchange, Queue ImportError: cannot import name Exchange C:\Users\Administrator>python Python 3.2 (r32:88445, Feb 20 2011, 21:29:02) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> from kombu import Exchange, Queue >>> print('WTF?!?')
