I hate it when marketing people decide they're technical - quote from a conference talk I regrettably sat through:

"The fourth industrial revolution is here, and you need to make sure you invest in every aspect of it - otherwise you'll be left in the dust by companies that are adopting big data, blockchain, quantum computing, nanotech, 3D printing and the internet of things."

Dahhhhhhhhhh

I really look forward to getting rid of end user and front end crap!

Just wasted 3 hours because of a bug report of a client stating, that "the printouts always have a useless empty page after the desired content".
Well, yeah. There actually is content on the site that's meant to be printed.
After 3 hours of fine-tuning and debugging I found out, that the content is in A4 (European default paper format: 210x297mm) and the customer tried printing in some weird ~219.9x279.4mm format. Apparently that's the US 8x11" letter format.

Two security researchers have published details about a vulnerability in the Windows Printing Service which impacts all Windows versions.

According to a Report of ZDNet : The vulnerability codenamed 'PrintDemon' which is located in Windows Print Spooler (Windows component responsible for managing print operations). The service sends data to be printed to a USB port for physically connected printers. In a report published, security researchers Alex Ionescu & Yarden Shafir said they found a bug in this old component that can be abused to hijack the Printer Spooler internal mechanism. The bug can not be used to break into a Windows client remotely over the internet, so it's not something that could be exploited to hack Windows systems over the internet.
