Searching for the right pattern to handle login data

- by stevebot

Hi all, I'm working on a controller that handles logins for a Web app. These logins will come from multiple clients but will all contain the same data. However, depending on the client, this data will be interpreted into common entities for our webapp differently. For instance, we have a user code that gets sent in, and in one case we may use the first four digits of the code, and in another case 12 digits of the code to map to a field on a User entity. Instead of handling this all in the controller and having big nasty if blocks of logic, I would like to use a pattern to handle how this information gets ingested into our application. What are your opinions?

Java technologies for web-development.

- by Alex

Hello. I'm PHP-programmer, but I'm extremely interested in learning Java. So I decided to change speciality from PHP to Java. At the moment I have an opportunity to try to make quite simple web-application (it should contain 2-3 forms, several pages with information from the database and authorization module) and also I have a chance to choose any technology I want. Besides I have about 3 months for this task. I've decided to develop site with Java technologies for the purpose of studying. I've already read a book about Java ("Java2 Complete Reference" by P.Naughton) and currently I'm reading "Thinking in Java" by B.Eckel. I clearly understand it's not enough for efficient development, but I want, at least, to try. I would be very appreciated for the advises, which framework (for example) or technology to choose (Spring, Grails etc.) and what primary aspects and technologies of Java should I pay attention to? Thank you in advance.

Free service that allows storing game data online?

- by StackedCrooked

I have created a small game in Java and I would like to add the ability for a player to publish his highscores online. I'm willing to write the server software myself (it's easy these days with Ruby Mongrel, or even C++). All I just need to have some sort hosting. One solution that immediately comes to mind is Amazon EC2. But that's kind of expensive for my needs. Since the requirements are very minimal (I don't even need a website, just a web service) I think there may be a cheaper solution out there. Does anyone know of a free or cheap provider for this kind of thing?

is it possible to use a python scrapper in a website?

- by Tom

I want to scrap a website and use that content in a website of my own. I am just wondering if that can be done with python 2.7, and if so how? If not, do I have to use JavaScript to scrap it? And do you have a good place to learn how to do that or good libraries for it. For those of you wondering, the website I am scrapping is legal, and they allow for this to be done. I have searched all over but apparently nobody tries to implement these scrappers that they write. I can write a web scrapper in python just fine. Say my scrapper scraps a name from a wikipedia page (John Doe for example), how can I use that name that I get in my website? Another update, I have found pjsrape and PhantomJS. I have only found one stack overflow post and the github examples with aren't very intuitive. If anybody has any experience or better ways to do it I would very much appreciate it

Passing through lists from jQuery to the service

- by thedixon

I'm sure I've done this in another solution, but I can't seem to find any solution as to do it again and wondered if anyone can help me... This is my WebAPI code: public class WebController : ApiController { public void Get(string telephone, string postcode, List<Client> clients) { } } And, calling this from jQuery: function Client(name, age) { this.Name = name; this.Age = age; } var Clients = []; Clients.push(new Client("Chris", 27)); $.ajax({ url: "/api/Web/", data: { telephone: "999", postcode: "xxx xxx", clients: Clients } }); But the "clients" object always comes back as null. I've also tried JSON.stringify(Clients), and this is the same result. Can anyone see anything obvious I'm missing here?

Need suggestions on which web frameworks to use?

- by satish

I want to build a site where people can create their personal websites quickly. All their websites will be hosted on my single web application (i.e. there will be only one database which contains info of all the websites). Each person will have an account where he can customize his website (template, content etc.). They can access their website from .mysite.com or mysite.com/xyz. I should be able to add different modules frequently, which will immediately reflect in all the websites created through my site. Based on the above requirements, please suggest me if there are any frameworks to use which can ease my job. Also suggest me which language to use (php or java). Which one would be better.

Giving users a "reputation system" - Should I... ?

- by RadiantHex

Hi folks, I'm thinking of adding a reputation system to a web application, the site is already being used so I'm trying to be careful about my choices. I'm developing in Django/Python, thought this would be important. Reputation is generated in all actions that contribute to the site, similar to Stackoverflow's system. I know there are literally millions of ways of implementing this, and this is why I feel quite lost. Two alternatives I am not sure about are: Keep track of reasons why reputation was incremented Ignore reasons in order to reduce complexity of the site and overhead Would be happy with a few pointers, and directions. Would be very much appreciated!

Best way to access a sqlite database file in a web service.

- by rogernorling

First question from me on stack overflow. I have created a java web application containing a web service using netbeans (I hope a web application were the correct choice). I use the web application as is with no extra frameworks. This web service use a sqlite JDBC driver for accessing a sqlite database file. My problem is that the file path end up incorrect when I try to form the JDBC connection string. Also, the working directory is different when deploying and when running JUnit tests. I read somewhere about including the file as a resource, but examples of this were nowhere to be seen. In any case, what is the best way to open the sqlite database, both when the web service is deployed and when I test it "localy"? I don't know much about web services, I just need it to work, so please, help me with the technicalities.

Client no longer getting data from Web Service after introducing targetNamespace in XSD

- by Laurence

Sorry if there is way too much info in this post – there’s a load of story before I get to the actual problem. I thought I‘d include everything that might be relevant as I don’t have much clue what is wrong. I had a working web service and client (both written with VS 2008 in C#) for passing product data to an e-commerce site. The XSD started like this: <xs:schema id="Ecommerce" elementFormDefault="qualified" xmlns:mstns="http://tempuri.org/Ecommerce.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="eur"> <xs:complexType> <xs:sequence> <xs:element ref="sec" minOccurs="1" maxOccurs="1"/> </xs:sequence> etc Here’s a sample document sent from client to service: <eur xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="ECommerce_WebService" type="product" method="GetLastDateSent" chunk_no="1" total_chunks="1" date_stamp="2010-03-10T17:16:34.523" version="1.1"> <sec guid="BFBACB3C-4C17-4786-ACCF-96BFDBF32DA5" company_name="Company" version="1.1"> <data /> </sec> </eur> Then, I had to give the service a targetNamespace. Actually I don’t know if I “had” to set it, but I added (to the same VS project) some code to act as a client to a completely unrelated service (which also had no namespace), and the project would not build until I gave my service a namespace. Now the XSD starts like this: <xs:schema id="Ecommerce" elementFormDefault="qualified" xmlns:mstns="http://tempuri.org/Ecommerce.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.company.com/ecommerce" xmlns:ecom="http://www. company.com/ecommerce"> <xs:element name="eur"> <xs:complexType> <xs:sequence> <xs:element ref="ecom:sec" minOccurs="1" maxOccurs="1" /> </xs:sequence> etc As you can see above I also updated all the xs:element ref attributes to give them the “ecom” prefix. Now the project builds again. I found the client needed some modification after this. The client uses a SQL stored procedure to generate the XML. This is then de-serialised into an object of the correct type for the service’s “get_data” method. The object’s type used to be “eur” but after updating the web reference to the service, it became “get_dataEur”. And sure enough the parent element in the XML had to be changed to “get_dataEur” to be accepted. Then bizarrely I also had to put the xmlns attribute containing my namespace on the “sec” element (the immediate child of the parent element) rather than the parent element. Here’s a sample document now sent from client to service: <get_dataEur xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="ECommerce_WebService" type="product" method="GetLastDateSent" chunk_no="1" total_chunks="1" date_stamp="2010-03-10T18:23:20.653" version="1.1"> <sec xmlns="http://www.company.com/ecommerce" guid="BFBACB3C-4C17-4786-ACCF-96BFDBF32DA5" company_name="Company" version="1.1"> <data /> </sec> </get_dataEur> If in the service’s get_data method I then serialize the incoming object I see this (the parent element is “eur” and the xmlns attribute is on the parent element): <eur xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.company.com/ecommerce" class="ECommerce_WebService" type="product" method="GetLastDateSent" chunk_no="1" total_chunks="1" date_stamp="2010-03-10T18:23:20.653" version="1.1"> <sec guid="BFBACB3C-4C17-4786-ACCF-96BFDBF32DA5" company_name="Company" version="1.1"> <data /> </sec> </eur> The service then prepares a reply to go back to the client. The XML looks like this (the important data being sent back is the date_stamp attribute in the last_sent element): <eur xmlns="http://www.company.com/ecommerce" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="ECommerce_WebService" type="product" method="GetLastDateSent" chunk_no="1" total_chunks="1" date_stamp="2010-03-10T18:22:57.530" version="1.1"> <sec version="1.1" xmlns=""> <data> <last_sent date_stamp="2010-02-25T15:15:10.193" /> </data> </sec> </eur> Now finally, here’s the problem!!! The client does not see any data – all it sees is the parent element with nothing inside it. If I serialize the reply object in the client code it looks like this: <get_dataResponseEur xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" class="ECommerce_WebService" type="product" method="GetLastDateSent" chunk_no="1" total_chunks="1" date_stamp="2010-03-10T18:22:57.53" version="1.1" /> So, my questions are: why isn’t my client seeing the contents of the reply document? how do I fix it? why do I have to put the xmlns attribute on a child element rather than the parent element in the outgoing document? Here’s a bit more possibly relevant info: The client code (pre-namespace) called the service method like this: XmlSerializer serializer = new XmlSerializer(typeof(eur)); XmlReader reader = xml.CreateReader(); eur eur = (eur)serializer.Deserialize(reader); service.Credentials = new NetworkCredential(login, pwd); service.Url = url; rc = service.get_data(ref eur); After the namespace was added I had to change it to this: XmlSerializer serializer = new XmlSerializer(typeof(get_dataEur)); XmlReader reader = xml.CreateReader(); get_dataEur eur = (get_dataEur)serializer.Deserialize(reader); get_dataResponseEur eur1 = new get_dataResponseEur(); service.Credentials = new NetworkCredential(login, pwd); service.Url = url; rc = service.get_data(eur, out eur1);

Creating a user account on a mac you don't have admin access to [migrated]

- by mouse

I am trying to create a user account on a school computer so I can run processes (like compiling large libraries) with admin permissions settings. This way I can walk away and let other people user the computer, and come back after class to retrieve the binaries. Usually some smart person decides to shut the machine down, but if I had higher permissions they wouldn't be able to terminate my processes. Right now I use the guest account, which everyone has access to. If you think this is in some way unethical or a bad idea, please criticize. tl,dr I tried using the dscl series of commands in single user mode as root, as recommended by this site. It returns this error: Cannot open remote host, error: DSOpenDirServiceErr How can I create a local user on this machine to compile my code with higher permissions?

Can not find Picasa Web Album, under Google App admin panel/google app/Other Google Services

- by PMaly

We got a Google App account that we use with our domaine name. We use the core service apps (gmail, calendar, drive, etc.). Now we are looking into going into Google+. To be able active Google+ for my users, I need to activate Picasa Web Album first. But I can't find it anywhere in my admin panel. It's suppose to be under Google Apps/Add Services/Other Services, but it's not. The only thing I see there is "Google App Engine" and "Google Apps Marketplace". Is it because I don't have Google Apps for business account? Thanks.

How to recertify Notes .id file if you can't get into Notes Admin

- by Ben

I've got a bit of a catch-22 situation here. My company used to use Notes, but migrated to Exchange several years ago. As such the Notes server was mothballed. I now need to get back into Notes to get some data from an old app we had. The trouble is, all my .id files have expired. I can't recertify them, as I can't log into Notes Admin - because the .id has expired. Is there any way round this? Thanks, Ben

Should EC2 server self register or have admin server

- by hortitude

I'm creating AWS servers using chef. I am also planning on enabling auto-scaling. While we have automatic monitoring setup already (server density or nagios etc), I was also going to setup the cloud watch alarm for the status check on the server. This led me down the path of trying to decide whether to install the ec2-command-line tools on the server itself (which then requires me to install java on the servers -- despite no other need for Java in our environment) or to possible have an "admin" box that will check periodically for servers and make sure they have their alarms set. I expect this paradigm to carry over to other things we want to configure (perhaps ensuring that termination protection is setup on production servers?). Any thoughts as to why to go one direction or another?

Coding exercise for Linux Systems Admin?

- by Prashanth Sundaram

Hello All, I am preparing for a Systems Admin(linux) role for a big company(top 10 companies) and one of the requisite is knowledge of a language like perl, python or Ruby. I have a phone interview which involves sharing a editor with the interviewer, now what kind of coding exercise can I expect on a phone interview or a regular interview? I have used shell for most of my day-to-day tasks and occasionally Perl and python for bigger tasks. Now I don't expect them to ask Write a script that sync's AD users to LDAP? I don't think data structures, algorithms or sorting questions apply to me role? Can you give me any examples of SysAdmin related coding questions?

Cannot remove wireless network profile even though admin account is used

- by David Karlsson

On my windows computer which is connected to a company domain. I have problems with the wireless networking. First of all the computer fails to connect. Second of all I cannot remove the network from the list of wireless profiles. The properties window simply claims that "This network is administered by the Administartor Account". I am currently logged in as the local administrator. I have also tried creating a new admin account and still get the same problem when trying to remove the network. My computer has only the microsoft security essentials antivirus and some VMWare+virtual box connections that I can figure might interfere, but disabling realtime protection has not helped me on this. I also cannot delete the virtual network adapters from the control panel / network adapters...

Cannot WMI Query root\MSCluster namespace as Local Admin

- by Matt Zuberko

I'm trying to use WMI Explorer to query the root\MSCluster namespace on various hosts to obtain cluster resource group and resource object data. I can access the namespace with no issue on Win2K3 cluster nodes but am getting an access denied error attempting to connect to Win2K8 and Win2K8R2 nodes. I can access the root\cimv2 namespace with no issue, just the MSCluster namespace even though I am a local Admin. Is there a feature setting, local security policy or server role I have to be a member of to access the namespace? Thank you!

I have a web application with its respective site collection and sites, i have anonymous access allowed for all the sites with forms authentication. Everything is working fine but i don't know how to login with the administrator account from the internet. With Windows auth you have the "login" link and you just have to use your admin credentials, how can i do that with forms auth?? Any help will be highly appreciated. Thanks in advance.

Windows 7 admin denied access to taskmgr, system32 dir

- by DotNet Zebra

I have a Windows 7 (32-bit) box with 2 users, both admins (my wife and I are both developers). My admin account was created during Windows setup, hers was created later. Both accounts are in the same groups, yet we have VERY different permissions. In the beta and RC, both accounts worked identically (RC to RTM was a fresh install on this box, not an upgrade). I have a C:\bin folder with the sysinternals utilities and a bunch of other stuff. Running anything in there or in system32 just works on my account, on hers I get access denied errors (cannot access file or path). If I right click and try Run As Administrator, I still get the same thing!!!

Moving LiveMeeting admin functions to a different window

- by Rob Farley

I run a user group, and often host LiveMeeting sessions. I use a projector, with a crowd watching. How do I do the admin stuff (respond to Q&A, etc) on one window, and just have the video on the 'extended monitor'? I dont' want the people in the audience to see anything except the video feed, but I want to be able to watch questions come in, etc... Note: I don't have a problem extending the screen across the two monitors - I already have different stuff showing on my screen compared to the projector. I just want a way to put the LM video on Monitor 2 (projector), and the LM controls on Monitor 1.
