NVIDIA 開源 Linux GPU Kernel Driver
NVIDIA 宣佈開源 Linux 下的 GPU Kernel Driver：「NVIDIA Releases Open-Source GPU Kernel Modules」。
從一些描述上可以看出來，應該是因為 Datacenter 端的動力推動的，所以這次 open source 的版本中，對 Datacenter GPU 的支援是 production level，但對 GeForce GPU 與 Workstation GPU 的支援直接掛 alpha level：
Which GPUs are supported by Open GPU Kernel Modules?
Open kernel modules support all Ampere and Turing GPUs. Datacenter GPUs are supported for production, and support for GeForce and Workstation GPUs is alpha quality. Please refer to the Datacenter, NVIDIA RTX, and GeForce product tables for more details (Turing and above have compute capability of 7.5 or greater).
然後 user-mode driver 還是 closed source：
Will the source for user-mode drivers such as CUDA be published?
These changes are for the kernel modules; while the user-mode components are untouched. So the user-mode will remain closed source and published with pre-built binaries in the driver and the CUDA toolkit.
對 nouveau 來說，是可以從 open source driver 裡面挖一些東西出來用，不過能挖到跟 proprietary 同樣效能水準嗎？

hashcat v3.00
hashcat 是個用暴力法拿來計算各種 reverse hash 的的工具，也就是對於 HASH(key) = value 時，給 value 的值，要求得出 key 的值 (被稱為 Preimage attack)。 雖然是暴力法，但還是花了很多力氣加速，尤其在這個 GPU 已經很常見的年代，這套軟體也支援透過 GPU 加速運算。 先前的版本是 CPU 與 GPU 分開兩個版本可以用 (CPU 版本的叫 hashcat，GPU 版本的叫做 oclHashcat)，而 GPU 的版本只支援 nVidia 與 AMD 兩家大廠的顯卡。 而在 v3.00 版，透過 OpenCL 的界面將這些全部都合而為一了：「hashcat v3.00」，所以不只是支援 CPU 與 nVidia + AMD 的 GPU，還包括了：…

更多瀏覽器內 GPU fingerprint 的技巧
在「Your device's GPU may be used for fingerprinting purposes」這邊看到有研究單位找出更多 GPU fingerprint 的技巧，論文在「DRAWNAPART: A Device Identification Technique based on Remote GPU Fingerprinting」這邊可以翻到，另外一些 source code 可以在 GitHub 上的「Drawn Apart」這邊可以翻到。 看起來是透過 WebGL 去建立模型： The researchers ran experiments on 2500 unique devices using the technique. They developed two methods, both of which use the…
