  • jQuery - $.each loop through json code

    - by Ice
    Due to the way my serverside script outputs I receive multiple JSON objects. {jsonhere}{jsonhere1}{jsonhere2}{jsonhere3} etc.. They aren't seperated by anything. If I would do a split based }{ I would lose those brackets. So is there an outerloop I can put over the regular $.each loop to make this work? Thank you, Ice

  • Overriding Debian default groups from LDAP

    - by Ex-Parrot
    This is a thing that has always bothered me: how am I best to handle Debian standard groups for LDAP users? Debian has a number of groups defined by default, e.g. plugdev, audio, cdrom and so on. These control access in standard Debian installs. When I want a user from LDAP to be a member of the `audio' group on all machines they log in to, I've tried a few different things: Adding them to the local group on the machine (this works but is hard to maintain) Creating a group in LDAP with the same name and a different GID then adding the user to that group (breaks reverse / forward GID mapping, doesn't seem to work) Creating a group in LDAP with the same name and same GID and adding the user to that group (doesn't seem to work at all, things don't see the LDAP group members) Creating a group in LDAP with the same name and same GID then removing the local group (this works but upsets Debian's maintenance scripts during upgrades that check for local system sanity) What's the best practice for this scenario?

  • How can we implement change notification propagation for WPF and SL in the MVVM pattern?

    - by Firoso
    Here's an example scenario targetting MVVM WPF/SL development: View data binds to view model Property "Target" "Target" exposes a field of an object called "data" that exists in the local application model, called "Original" when "Original" changes, it should raise notification to the view model and then propogate that change notification to the View. Here are the solutions I've come up with, but I don't like any of them all that much. I'm looking for other ideas, by the time we come up with something rock solid I'm certain Microsoft will have released .NET 5 with WPF/SL extensions for better tools for MVVM development. For now the question is, "What have you done to solve this problem and how has it worked out for you?" Option 1. Proposal: Attach a handler to data's PropertyChanged event that watches for string values of properties it cares about that might have changed, and raises the appropriate notification. Why I don't like it: Changes don't bubble naturally, objects must be explicitly watched, if data changes to a new source, events must be un-registered/registered. Why I kind of like it: I get explicit control over propogation of changes, and I don't have to use any types that belong at a higher level of the application such as dependancy properties. Option 2. Proposal: Attach a handler to data's PropertyChanged event that re-raises the event across all properties using the name property name. Why I don't like it: This is essentially the same as option 1, but less intelligent, and forces me to never change my property names, as they have to be the same as the property names on data Why I kind of like it: It's very easy to set up and I don't have to think about it... Then again if I try to think, and change names to things that make sense, I shoot myself in the foot, and then I have to think about it! Option 3. Proposal: Inherit my view model from dependancy object, and notify binding sources of changes directly. Why I don't like it: I'm not even 100% sure dependancy properties/objects can DO this, it was just a thought to look into. Also I don't personally feel that WPF/SL types like Dep Obj belong at the view model level. Why I kind of like it: IF it has the capability that I'm seeking then it's a good answer! minus that pesky layering issue. Option 4. Proposal: Use a consistant agent messaging system based off of Task Parallels DataFlow Library to propogate everything through linked pipelining. Why I don't like it: I've never tried this, and somehow I think it will be lacking, plus it requires me to think about my code completely differently all the way around. Why I kind of like it: It has the possiblity of allowing me to do some VERY fun manipulations with a push based data model and using ActionBlocks as validation AND setters to then privately change view model properties and explicitly control PropertyChanged notifications.

  • Xcode: Internal error occurred while creating dependency graph

    - by Randy Simon
    I just started getting this error today, seemingly out of nowhere. Any one see this before and know what causes it. Internal error occurred while creating dependency graph: *** -[NSCFArray initWithObjects:count:]: attempt to insert nil object at objects[10] This happens when I try to build with "iPhone Device 3.x" selected. However, if I select "iPhone Simulator 3.x", everything is fine.

  • PowerShell - Shorten namespace names so it's easier to access types

    - by Adam Driscoll
    Is there a method of shortening PowerShell namespace references? Typing [RootNameSpace1.NameSpace2.Namepsace3+SomeEnum]::SomeValue is taxing and not a very good user expierence. I realize that you can reference System level objects without a namespace such that [Type]::GetType(... will work. Is there some manifest I could create or command I could use to shorten lengthy namespaces?

  • How test guice injections?

    - by yeraycaballero
    I gave to Google Guice the responsability of wiring my objects. But, How can I test if the bindings are working well. For example, suppose we have a class A which has a dependence B. How can I test than B is injected correctly. class A { private B b; public A() {} @Inject public void setB(B b) { this.b = b } } Notice A hasn't got a getB() method and I want to assert that A.b isn't null.

  • How can I get a call stack listing in Perl?

    - by slashmais
    Is there a way I can access (for printout) a list of sub + module to arbitrary depth of sub-calls preceding a current position in a Perl script? I need to make changes to some Perl modules (.pm's). The workflow is initiated from a web-page thru a cgi-script, passing input through several modules/objects ending in the module where I need to use the data. Somewhere along the line the data got changed and I need to find out where.

  • prevent domain controller using wpad for windows update

    - by BeowulfNode42
    We have a 2012 domain controller in an environment where we are running a web proxy auto discovery (WPAD) setup for client devices, and that proxy server requires authentication. However windows update does not support proxy servers requiring authentication. So we want to prevent windows update on our servers from using the WPAD proxy settings. On a domain member server we can log in to the local administrator account (not domain admin) and un-tick the the "Auto detect proxy settings" in IE internet options and that fixes the issue on those servers. But a domain controller does not have a local admin account, as that account is the domain admin account. Doing this to the domain admin account on the DC does not prevent it from using WPAD. Our whole purpose of running a proxy server that requires authentication is so we can identify what the users on our session based remote desktop servers are doing on the internet. See this MS KB Article for some info about Windows update and proxy servers "How the Windows Update client determines which proxy server to use to connect to the Windows Update Web site" - http://support.microsoft.com/kb/900935

  • Classic ASP vs. ASP.NET encryption options

    - by harrije
    I'm working on a web site where the new pages are ASP.NET and the legacy pages are Classic ASP. Being new to development in the Windows env, I've been studying the latest technology, i.e. .NET and I become like a deer in headlights when ever legacy issues come up regarding COM objects. Security on the website is an abomination, but I've easily encrypted the connectionStrings in the web.config file per http://www.4guysfromrolla.com/articles/021506-1.aspx based on DPAPI machine mode. I understand this approach is not the most secure, but it's better than nothing which is what it was for the ASP.NET pages. Now, I question how to do similar encryption for the connection strings used by the Classic ASP pages. A complicating factor is that the web sited is hosted where I do not have admin permissions or even command line access, just FTP. Moreover I want to avoid managing the key. My research has found: DPAPI with COM interop. Seems like this should already be available, but the only thing I could find discussing this is CyptoUtility (see http://msdn.microsoft.com/en-us/magazine/cc163884.aspx) which is not installed on the hosting server. There are plenty of other third party COM objects, e.g. Crypto from Dalun Software http://www.dalun.com, but these aren't on the hosted server either, and they look to me to require you to do some kind of key management. There is CAPICOM on the hosted server, but M$ has deprecated it and many report it is not the easiest to use. It is not clear to me whether I can avoid key management with CAPICOM similar to using DPAPI for ASP.NET. If anyone happens to know, please clue me in. I could write an web service in ASP.NET and have the classic ASP pages use it to get the decrypted connection strings and then store those in an application variable. I would not need to use SSL since I could use localhost and nothing would be sent over the internet. In the simpliest form I could implement what someone termed a poor man's version based on a simple XML stream, however, I really was looking to avoid any development since I find it hard to believe there is not a simple solution for Classic ASP like there is for ASP.NET. Maybe I'm missing some options... Recommendations are requested...

  • Windows 2008 R2 Scheduled Task Not Running With Admin Privileges even if granted?

    - by j.rightly
    I have a scheduled task that is running as USER. I have checked the box "Run with highest privileges" in the scheduled task properties. The task is a powershell script that, among other things, reboots the system. The script executes and runs normally, but as a scheduled task, it fails to reboot the system. Here is the kicker: When I manually run the script as USER using the exact same command line as what's in the scheduled task, the script still runs but this time it actually reboots the system. I have UAC disabled and USER is a member of the local Admins group. The local Admins group has the right to shut down the system. Nothing in the event logs offers any clues. Why would the same script running under the same credentials work interactively but not as a scheduled task? UPDATE: This is too weird. When the task ran on schedule, everything worked normally.

  • Using a custom form in a modelformset factory?

    - by jamida
    I'd like to be able to use a customized form in a modelformset_factory. For example: models.py class Author(models.Model): name = models.CharField() address = models.CharField() class AuthorForm(ModelForm): class Meta: model = Author views.py def test_render(request): myModelFormset = modelformset_factory(Author) items = Author.objects.all() formsetInstance = myModelFormset(queryset = items) return render_to_response('template',locals()) The above code works just fine, but note I'm NOT using AuthorForm. The question is how can I get the modelformset_factory to use the AuthorForm (which I plan to customize later) instead of making a default Author form?

  • ssl between balancer members?

    - by jemminger
    I have apache running on one machine as a load balancer: <VirtualHost *:443> ServerName ssl.example.com DocumentRoot /home/example/public SSLEngine on SSLCertificateFile /etc/pki/tls/certs/example.crt SSLCertificateKeyFile /etc/pki/tls/private/example.key <Proxy balancer://myappcluster> BalancerMember http://app1.example.com:12345 route=app1 BalancerMember http://app2.example.com:12345 route=app2 </Proxy> ProxyPass / balancer://myappcluster/ stickysession=_myapp_session ProxyPassReverse / balancer://myappcluster/ </VirtualHost> Note that the balancer takes requests under SSL port 443, but then communicates to the balancer members on a non-ssl port. Is it possible to have the forwarding to the balancer members be under SSL too? If so, is this the best/recommended way? If so, do I have to have another SSL cert for each balancer member? Does the SSLProxyEngine directive have anything to do with this?

  • How to set Content-Type header charset in OpenRasta

    - by Sergey Mirvoda
    When I return my object as JSON via JsonDataContractCodec OpenRasta sets Content-Type header to application/json but ignores charset part of content type. When I use Chrome it sends GET request with folowing header: Accept-Charset:windows-1251,utf-8;q=0.7,*;q=0.3 and all my utf-8 encoded json objects goes wrong. I tried to override OperationResult with no luck. OpenRasta overwrites my header with codec's one.

  • Returning IEnumerable from an indexer, bad practice?

    - by fearofawhackplanet
    If I had a CarsDataStore representing a table something like: Cars -------------- Ford | Fiesta Ford | Escort Ford | Orion Fiat | Uno Fiat | Panda Then I could do IEnumerable<Cars> fords = CarsDataStore["Ford"]; Is this a bad idea? It's iconsistent with the other datastore objects in my api (which all have a single column PK indexer), and I'm guessing most people don't expect an indexer to return a collection in this situation.
