Create own delegate control
In this post I’ll show how to create a simple (but own) delegate control. A short intro and links on delegate controls can be found on sharepointoverflow. Take a look on master page. There are already many delegate controls. The delegate control with id AdditionalPageHead can be used for adding your script or jQuery library.:
<SharePoint:DelegateControl runat="server" ControlId="AdditionalPageHead" AllowMultipleControls="true"/> You can also override existing controls like searchbox. But what if you want to add some content in the master page where no delegate controls are present.

SiteLogoImage to RootWeb
If you click on the site logo, as default you go to the current spweb’s default.aspx page. If you want to override this, locate:
<SharePoint:SPLinkButton runat="server" NavigateUrl="~site/" id="onetidProjectPropertyTitleGraphic" > ```Change ~site to ~sitecollection: <SharePoint:SPLinkButton runat=“server” NavigateUrl="~sitecollection/" id=“onetidProjectPropertyTitleGraphic” >

Hide Site Actions
The easiest way to hide Site Actions for a specific audience is to wrap this into a SPSecuritityTrimmingControl. Locate in your master page. Paste this before span element:
<SharePoint:SPSecurityTrimmedControl runat="server" Permissions="ManageLists"> Find the ending element and paste:
</SharePoint:SPSecurityTrimmedControl>

Get all comments
If you try to get comments quantity for a url, you may wonder, why there is only quantity of the comments which the current user has posted:
public int GetNumberOfNewsPageComments (SPSite currentSite, string pageUrl, int max) { var serviceContext = SPServiceContext.GetContext(currentSite); var socialCommentManager = new SocialCommentManager(serviceContext); var comments = socialCommentManager .GetComments(new Uri(pageUrl), max); if (comments != null) { return comments.Length; } return -1; } ```The solution is to impersonate the SPSite object with an account who has the rights to manage social data.

Custom favicon
It is easy to use a custom favicon, put a ico image into a mapped folder Images and then locate this line in your master page:
<SharePoint:SPShortcutIcon runat="server" IconUrl="/\_layouts/images/favicon.ico" /> ```And replace it with your ico: <SharePoint:SPShortcutIcon runat=“server” IconUrl="/_layouts/images/CONTOSO/favicon.ico" />

Do an unsafe update in a unified manner
Recently I talked about a WithWeb-pattern as described in Jonas Nilssons blog where you can isolate the disposal logic in one place. Another thing is to isolate unsafe updates:
public static class SPWebExtension { public static void UnsafeUpdate(this SPWeb web, Action<SPWeb> action) { try { Log.Info("Trying to do an unsafe update on a web: " + web.Title); web.AllowUnsafeUpdates = true; action(web); } catch (Exception e) { Log.Error(e); } finally { web.
