• Defining - and dealing with - Evil

  - by Chris Becke

  As a software developer one sometimes gets feature requests that seem to be in some kind of morally grey area. Sometimes one can deflect them, or implement them in a way that feels less 'evil' - sometimes - on reflection - while the feature request 'feels' wrong theres no identifiable part of it that actually causes harm. Sometimes one feels a feature is totally innocent but various anti virus products start tagging one as malware. For example - I personally consider EULAs to (a) hopefully be unenforceable and (b) a means by which rights are REMOVED from consumers. However Anti Virus scanners frequently mark as malware any kind of download agent that does not display a EULA. Which to me is the result of a curious kind of double think. What I want to know is - are there any online (or offline) resources that cover evil software development practices? How can I know if a software practice that I consider dodgy is in fact evil enough to consider fighting?

• Changing MSSQL Database sorting

  - by plaisthos

  I have a request to change the collation of a MS SQL Database: ALTER DATABASE solarwind95 collate SQL_Latin1_General_CP1_CI_AS but I get this strange error: Meldung 5075, Ebene 16, Status 1, Zeile 1 Das 'Spalte'-Objekt 'CustomPollerAssignment.PollerID' ist von 'Datenbanksortierung' abhängig. Die Datenbanksortierung kann nicht geändert werden, wenn ein schemagebundenes Objekt von ihr abhängig ist. Entfernen Sie die Anhängigkeiten der Datenbanksortierung, und wiederholen Sie den Vorgang. Sorry for the german errror message. I do not know how to switch the language to english, but here is a translation: Translation: Message 5075, Layer 16, Status 1, Row 1 The 'column' object 'CustomPollerAssignment.PollerID' depends on 'Database sorting. The database sorting cannot be changed if a schema bound object depends on it. Remove the dependency of the database sortieren and retry. I got a ton more of the errors like that.

• How do I pass the currently logged in user's credentials to a web service using Integrated Windows A

  - by Chris Smith

  I am having a frustrating time trying to do something with Perl that would take a couple of lines of code in C#, namely to call a web service on a Windows server that requires Integrated Windows Authentication. The most likely candidate I've found for success is a module called LWP::Authen::Ntlm, but all the examples I've googled require you to explicitly supply username, password and domain. I don't want to do that - I just want the request to use the credentials of the currently logged in user, a la CredentialCache.DefaultCredentials in .NET. Have any of you Perl gurus out there ever had to do this? Thanks.

• Connect to https:// webservice in asp.net app

  - by webnoob

  Hi All, I have an ASP.NET website that is contacting a webservice. Everything works fine connecting via http but when I try https:// it can't connect. I don't seem to get any error from the website and the webservice logs show nothing, meaning nothing has connected to it. I can connect to my https:// webservice from a site like soapclient.com and request information, so the webservice and ports are working. Is there anything special I should be doing in order to connect to a https:// webservice over a normal http:// one in .NET? All I am doing at the moment is changing the URL it is connecting to to my secure one instead. I am using ASP.NET 2, IIS7 Thanks in advance.

• Get Janrain to work with Sproutcore?

  - by weng

  Since Sproutcore is not dependent on the backend server to render pages, I'm struggling on how to get it working with Janrain. In one of the login processes of Janrain a HTTP request is sent to a backend server that processes the information and render a logged in page to the user. Since I'm using Sproutcore and don't have a backend server but using CouchDB to serve Sproutcore I wonder how I am going to implement Janrain successfully. Even if I'm using a backend server like Node.js I'm still not sure how to implement Janrain. Has anyone implemented Janrain in a Sproutcore app?

• How to Create a Queue

  - by regex

  Hello All, I have an application built that hits a third party company's web service in order to create an email account after a customer clicks a button. However, sometimes the web service takes longer than 1 minute to respond, which is way to long for my customers to be sitting there waiting for a response. I need to devise a way to set up some sort of queuing service external from the web site. This way I can add the web service action to the queue and advise the customer it may take up to 2 minutes to create the account. I'm curious of the best way to achieve this. My initial thought is to request the actions via a database table which will be checked on a regular basis by a Console app which is run via Windows Scheduled tasks. Any issues with that method? Is there a better method you can think of?

• Why is NavigationHandler.handleNavigation() not forwarding to view ID?

  - by Erik Hermansen

  Inside of a phase listener class that runs during the "RESTORE_VIEW" phase, I have some code like this: public void afterPhase(PhaseEvent event) { FacesContext fc = event.getFacesContext(); NavigationHandler nh = fc.getApplication().getNavigationHandler(); nh.handleNavigation(fc, null, "/a/specific/path/to/a/resource.jspx"); } Navigation to the new URL doesn't work here. The request made will just receive a response from the original JSPX that was navigated to. Code like this works fine: public void afterPhase(PhaseEvent event) { FacesContext fc = event.getFacesContext(); NavigationHandler nh = fc.getApplication().getNavigationHandler(); nh.handleNavigation(fc, null, "OUTCOME_DEFINED_IN_FACES_CONFIG_XML"); } Also the first snippet will work with an IceFaces Faces provider, but not Sun JSF 1.2 which is what I need to use. Is there something I can do to fix the code so it is possible to forward to specific URLs?

• How can I copy a queryset to a new model in django admin?

  - by user3806832

  I'm trying to write an action that allows the user to select the queryset and copy it to a new table. So: John, Mark, James, Tyler and Joe are in a table 1( called round 1) The user selects the action that say to "move to next round" and those same instances that were chosen are now also in the table for "round 2". I started trying with an action but don't really know where to go from here: def Round_2(modeladmin, request, queryset): For X in queryset: X.pk = None perform.short_description = "Move to Round 2" How can I copy them to the next table with all of their information (pk doesn't have to be the same)? Thanks

• Logging into oracle db as a global user

  - by kineas

  We are trying to shape up an old, 2 tier, Delphi based application. It originally uses database authentication, we'd like to transform the db user accounts to global users, so an OID server could perform the authentication instead of the database. The Delphi program can no longer log into the database if the account is a global user. I'm trying to understand the login protocol, so far without results. Similar thing happens with SQLDeveloper, I can't connect as a global user. SQLPlus however works with both kinds of users. We checked the information flow with Wireshark. When the dbserver asks back for a password, the SQLPlus sends it, while the SQLDeveloper doesn't send a password when attempting to connect as a global user. The client sends the application name too in the login request. Is it possible that we have to store the client app name in the LDAP itself?

• Using htaccess rewrite to make a subdirectory be its own root for root relative path requests

  - by Scott

  Can I use htaccess to capture requests from a certain subdirectory and make that directory use itself as the root directory for any root relative path requests? For example if I have... http://www.example.com/subFIXED/subANY/restofpath ...where subFIXED is always the same directory, subANY is any immediate subdirectory of subFIXED, and I want a redirection of all href/src requests from any file under subANY to use subANY as the 'root' (sort of like a subdomain), in effect having root level requests use this as the root directory level: http://www.example.com/subFIXED/subANY/ Instead of this: http://www.example.com/ I'm assuming I can put an htaccess file in subFIXED to handle all calls coming from anything under any subANY, but not being very familiar with htaccess rewriting, variables, etc., I can't figure out how to capture which subANY directory is making the root level request and then use that capture to make a rewrite to consider that directory the root level of any root relative path requests from it. Thanks for your help

• Google Translation API not working for even one page long documents

  - by Saubhagya

  I'm using Google Translation API to translate text from Chinese Simplified to English in my C# program. The problem is if the text is small (around one line) the API is able to translate it, but if the text is larger (more than 3 lines) is gives an exception saying "The remote server returned an unexpected response: (414) Request-URI Too Large.". However if I use translate.google.com in my browser that works fine. Please tell me how can I process large documents using Google Translate API in my desktop application written in C#.

• Storing i18n data in a database using XML

  - by TigrouMeow

  Hello, I may have to store some i18n-ed data in my database using XML if I don't fight back. That's not my choice, but it's in the specifications I have to follow. We would have, by example, something like following in a 'Country' column: <lang='fr'>Etats-Unis</lang> <lang='en'>United States</lang> This would apply to many columns in the database. I don't think it's a good idea at all. I tend to think that a cell in a database should represent a single piece of data (better for look-up), and that the database should have two dimensions maximum and not 3 or more (one request more would be required per dimension / a dimension here would be equal to the number of XML attributes). My idea was to have a separate table for all the translations, with columns such as : ID / Language / Translation. However, I should admit that I'm really not sure what is the best way to store data in various languages in a DB... Thanks for your advices :)

• How to virtually delete data from multiple tables that are linked by a foreign key ?

  - by Shantanu Gupta

  I am using Sql Server 2005 This is a part of my database diagram. I want to perform deletion on my database which will start from tblDomain up tp tblSubTopics. Consider that each table has IsDeleted column which has to be marked true if request was made to delete data. But that data shoud remain their physically. Tables which will have IsDeleted Column are tblDomain tblSubject tblTopic tblSubTopic Now I want, if a user marks one domain as deleted then all the refrence field should also get marked as deleted. i.e. 1 domain is related to 5 subjects, those 5 subjects are related to 25 topics, those 25 topics are related to 500 subtopics and so on. Then how should i mark all these fileds as Deleted. ?

• Tomcat: recommandations for logging

  - by WizardOfOdds

  I've read several questions here concerning Tomcat and logging but I still really don't understand the "bigger picture", hence my question: How and where are my Webapps supposed to do their logging? By default on my setup Tomcat 6.0.20 logs go in the following file/appender: ./apache-tomcat-6.0.20/logs/catalina.out Am I suppose to have my webapps also log to this file/appender? Let say my case is trivially simple and I've got just one servlet: import ... // What do I import here in order to be able to log? public class SOServlet extends HttpServlet { public void doGet( final HttpServletRequest request, final HttpServletResponse response ) throws IOException, ServletException { ... // I want to log here, what do I write? What are the gotchas knowing that there are more than one webapp running on the same Tomcat? (apparently from reading the various questions there are many gotchas). What about the .war, do I need to put log4j/sl4f/commons-logging/whatever in my .war?

• Detecting regional settings (List Separator) from web

  - by Toms Mikoss

  After having the unpleasant surprise that Comma Seperated Value (CSV) files are not necessarily comma-separated, I'm trying to find out if there is any way to detect what the regional settings list separator value is on the client machine from http request. Scenario is as follows: A user can download some data in CSV format from web site (RoR, if it matters). That CSV file is generated on the fly, sent to the user, and most of the time double-clicked and opened in MS Excel on Windows machine at the destination. Now, if the user has ',' set as the list separator, the data is properly arranged in columns, but if any other separator (';' is widely used here) is set, it all just gets thrown into a single column. So, is there any way to detect what separator is used on the client machine, and generate the file accordingly? I have a sinking feeling that it is not, but I'd like to be sure before I pass the 'can't be done, sorry' line to the customer :)

• ASP.NET MVC: dealing with Version field.

  - by alex2k8

  I have a versioned model: public class VersionedModel { public Binary Version { get; set; } } Rendered using <%= Html.Hidden("Version") %> it gives: <input id="Version" name="Version" type="hidden" value="&quot;AQID&quot;" /> that looks a bit strange. Any way, when the form submitted, the Version field is always null. public ActionResult VersionedUpdate(VersionedModel data) { ... } How can I pass Version over the wire? EDIT: A naive solution is: public ActionResult VersionedUpdate(VersionedModel data) { data.Version = GetBinaryValue("Version"); } private Binary GetBinaryValue(string name) { return new Binary(Convert.FromBase64String(this.Request[name].Replace("\"", ""))); }

• golang dynamically parsing files

  - by Brian Voelker

  For parsing files i have setup a variable for template.ParseFiles and i currently have to manually set each file. Two things: How would i be able to walk through a main folder and a multitude of subfolders and automatically add them to ParseFiles so i dont have to manually add each file individually? How would i be able to call a file with the same name in a subfolder because currently I get an error at runtime if i add same name file in ParseFiles. var templates = template.Must(template.ParseFiles( "index.html", // main file "subfolder/index.html" // subfolder with same filename errors on runtime "includes/header.html", "includes/footer.html", )) func main() { // Walk and ParseFiles filepath.Walk("files", func(path string, info os.FileInfo, err error) { if !info.IsDir() { // Add path to ParseFiles } return }) http.HandleFunc("/", home) http.ListenAndServe(":8080", nil) } func home(w http.ResponseWriter, r *http.Request) { render(w, "index.html") } func render(w http.ResponseWriter, tmpl string) { err := templates.ExecuteTemplate(w, tmpl, nil) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) } }

• Will client JVM for a web service(https) throw an SSL Exception when the server is having a valid ce

  - by ring bearer

  I have a web service deployed on tomcat hosted on a remote server. I have set it up such that it can be accessed only via HTTPS. For this, I generated a Certificate Signing Request (CSR) and used it to get a temporary certificate from VeriSign. My web service client is on my local machine. If I try to access the service it will throw a javax.net.ssl.SSLHandshakeException:unable to find valid certification path to requested target If I install the certificate in to local Java's keystore, the issue will be resolved. My question is if I install a valid SSL certificate from a CA in to my tomcat server, will I get this client-side error even if I do not import the certificate to local key store?

• Key word extraction in Python

  - by oliland

  I'm building a website in django that needs to extract key words from short (twitter-like) messages. I've looked at packages like topia.textextract and nltk - but both seem to be overkill for what I need to do. All I need to do is filter words like "and", "or", "not" while keeping nouns and verbs that aren't conjunctives or other parts of speech. Are there any "simpler" packages out there that can do this? EDIT: This needs to be done in near real-time on a production website, so using a keyword extraction service seems out of the question, based on their response times and request throttling.
