This is one of those, I believe -- Eric Ligman is Microsoft Senior Sales Excellence Manager (whatever that is) and he apparently posts large lists of free Microsoft-stack-related eBooks on his blog at MSDN, such as this list from a few weeks ago (which I think was mentioned on HN back then): http://blogs.msdn.com/b/mssmallbiz/archive/2015/07/07/i-m-giving-away-millions-of-free-microsoft-ebooks-again-including-windows-10-windows-8-1-windows-8-windows-7-office-2013-office-365-sharepoint-2013-dynamics-crm-powershell-exchange-server-lync-2013-system-center-azure-clo.aspx http://blogs.msdn.com/b/mssmallbiz/archive/2015/07/07/i-m-gi... As far as your needs are concerned, while there are no ebooks about programming languages in this list (aside from PowerShell), there's a bunch about SQL Server in the second half of the list and perhaps other things of interest as well.
