Sure thing. Thank you for helping to spread #ReactOS!
If you're going to steal my meme, could you at least give me credit?
During the development of #ReactOS 0.4.7, we switched from SVN to GitHub. That alone brought us lots of new contributors. Improved stability and usability over the years have speeded up our progress. Plus we do regularly share recent activity here ;)
You guys seem to be developing stuff way faster now!! I guess the project has picked up the pace, huh??
Running this gradient drawing test program caused total incorrect draw and crash of #ReactOS. Our developer Doug Lyons fixed the BSoD first, then squashed other bugs for correct drawing! Compare before-after shots.


Driver of NVIDIA GeForce 8400 GS works on #ReactOS! Test: Cat Fights

With QEMU, #ReactOS runs OS/2 Warp 4! Interestingly, both Task Manager and Process Explorer reports usage of 4 MB RAM only, even though virtual machine is set to use 256 MB. Shots by tompex.



#ReactOS installs and runs on Lenovo ThinkPad T530i! Installation was successful after a few specific BIOS tweaks. Intel HD 3000 graphics driver does not work. The official Lenovo LAN driver causes a BSoD, while a generic one from Snappy Driver Installer works perfectly.

Who is online for Hedgewars? Version 0.9.23 works with #ReactOS, on real hardware! Test by @julenuri.

Would you like to help #ReactOS instead, for transition from Server 2003 compatibility towards Vista?

Collaboration time! Simone Lombardo found a bug in our NDIS driver and Herve Poussineau fixed it: Driver for NETGEAR WG311v2 PCI WiFi card now works on #ReactOS! Even router page could be accessed!! See the before-after shots below.



This PC has audio working out of the box with #ReactOS! Tester is extremely lucky. ;) Improvements of audio stack in 0.4.15 allowed us to import driver for AC97-compatible sound cards. Few more drivers are usable. Many more apps have sound working, too!
