Open sociale netwerken

Net een post gelezen van Yme gisteren toegevoegd aan zijn blog getiteld Gemakkelijk netwerken. Yme verwijst hier naar een erg sterk betoog van Marc Canter: The Chess game of social networking.

Marc is de eigenaar van People Aggregator, een open social networking community. Je kunt je profiel eenvoudig van de ene omgeving overzetten naar de andere. Het is een kwestie van tijd wanneer de grote jongens zoals Facebook, LinkedIn, Hyves overstappen op het open concept. Pas als mensen zich massaal gaan realiseren dat hun gegevens achter slot en grendel zitten van hun gebruikte site gaat er pas wat in beweging komen.

In een reactie op Marcs verhaal wordt er verwezen naar een post van Syndeo::media: Portable profiles - Reducing the cost of joining a new social network. Hier worden een paar bestaande technologieën genoemd die mogelijk een basis kunnen vormen voor dergelijke portable profiles:

OpenID: een open authenticatie service à la Microsoft Passport, maar dan gedecentraliseerd. Iedereen kan zijn eigen OpenID service starten en iedereen mag zelf kiezen waar hij zijn OpenID account laat servicen. Het antwoord van Microsoft op decentrale authenticatie is trouwens Microsoft CardSpace.

FOAF: Friend-of-a-friend, een microformat "to create a Web of machine-readable pages describing people, the links between them and they create and do.".

Twee andere microformats:
  1. hCard, de XHTML tegenhanger van vCard om adresgegevens te specificeren;
  2. XFN, XHTML Friends Network, "a simple way to represent human relationships using hyperlinks".

Exploring advanced DOM interop with Blazor WebAssembly

Afbeelding
With the establishment of WebAssembly in the browser space, JavaScript is not the only option anymore to run code in the browser. You can start building your modern web applications in any language of choice. Recently Microsoft has released the first version of Blazor WebAssembly. It enables you as a .NET developer to run .NET code through WebAssembly. Blazor also comes with a websocket based server model. You can check out Blazor on Microsoft Docs: https://docs.microsoft.com/en-us/aspnet/core/blazor I have been building a couple of Blazor experiments myself, of which the following two stand out: Real-time Blazor server web app. I have added a second SignalR hub to this app in order to communicate signals from one Blazor session to another.

If I find time I will blog about all my adventures to getting this deep zoom Mandelbrot to work! Try it online It was the latt

Azure Custom Role Definitions and Assignment Scopes

Afbeelding
Working with custom Role Definitions in Azure can be a funny thing. Interestingly, when reviewing the Azure Active Directory user interface in Azure Portal you will not find a way to query all available role definitions. If you query the Roles and Administrators view you will only see administrator roles: With a PowerShell cmdlet you are able to list all. Get-AzRoleDefinition | select name | sort name | ft results in something like the following: Name ---- AcrDelete AcrImageSigner AcrPull AcrPush AcrQuarantineReader AcrQuarantineWriter API Management Service Contributor API Management Service Operator Role API Management Service Reader Role App Configuration Data Owner ... But are these really all the role definitions out there? Obviously not! This list is scoped to the subscription you are currently targeting with your current Azure Context. In order for you to try out yourself, just create a couple of role definitions with various assignment scopes. Assuming you have owne

Troubleshooting restoring a site collection

The following applies to SharePoint 2013 RTM and potentially to SharePoint 2010, but was not tested. Ever tried to backup and restore a site collection with PowerShell using a least privilege SPRestore account approach and bumped into some fatal errors? As a starter you should have followed the instructions that are documented on TechNet: Restore site collections in SharePoint 2013 http://technet.microsoft.com/en-us/library/ee748655.aspx Apparently this documention is not completely sufficient, as you bumped in some fatal errors and are seeking for help. In this blog I would like to discuss two error messages and show you how to address them. Error 1: access denied In PowerShell: 02/26/2013 15:38:27.95 PowerShell.exe (0x2B28) 0x2B78 SharePoint Foundation General ai1wu Medium System.UnauthorizedAccessException: Access is denied.
