Umm Microsoft is something wrong? Basic MSDN pages such as docs.microsoft.com/en-us/windows-… are not working. Searches for the corresponding functions show results for the same pages, but all the links appear to return the same 404 page not found errors, despite working yesterday.

How complicated is cellular baseband firmware?
At least this complicated: over 150K debugging messages across 932 directories and 2,775 files!
Rebuilding the source code skeleton from Samsung S10's Shannon S5000 baseband debugging messages.

That moment when you register for thread event notifications and forget to unregister before unloading your driver. Well guess I know what a DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS BSOD might be related to now :P

Just published a follow-up to my Adobe Reader symbols story on the Project Zero blog. Turns out there's even more debug metadata to be found in some old (and new) builds, including private CoolType symbols. Enjoy! googleprojectzero.blogspot.com/2020/01/part-i…

WinDBG seems to indicate my driver is never registered with PnP despite being a WDM driver (which confuses me as according to docs.microsoft.com/en-us/windows-… the WDM drivers should support PnP as a requirement). (2/2)

Anyone had any experience with IoOpenDeviceRegistryKey() who might be able to tell me if a WDM driver needs to perform any special function calls prior to calling this? Been trying for a while now to get this call to work but all signs, including running !devnode 0 1 in (1/2)

Fascinating to compare the half-life of content across platforms (time it takes for a piece of content to reach 50% of its total lifetime engagement) 🧐
