Time of writing: Jan 18, 2023. The following assume you're trying to install CUDA on WSL2 Ubuntu.
Check support matrix first before you install any version of CUDA, because chances are the latest CUDA does not have cuDNN support yet, then you'll have to re-install older version if you found out later.

https://docs.nvidia.com/deeplearning/cudnn/support-matrix/index.html#cudnn-cuda-hardware-versions

At the time of writing, the latest cuDNN version is 8.7 and it supports CUDA 11.8.
Windows 10 must be build 20145 or later.

Updating a HP(E) server from iLO 3 version 1.55 to version 1.94

This short document explain how to resolve the issues arising when trying to update an old (Gen7) HP(E) server to the most recent iLO 3 (HPE Integrated Lights-Out) version, which solves a great number of security and usability issues.

Issues

Can't connect to iLO with a modern browser, for lack of supported TLS protocol version
- solved by using FirefoxPortable version 31
- and in the Firefox31 portable configuration, in the about:config settings, set security.tls.version.min (the minimum acceptable version of the TLS protocol) to 0 in order to be able to negociate down to TLS 1.0 (even if iLO 3 can do 1.1). Keep in mind your browser is now (even more) vulnerable to a host of attacks, do not connect to any potentially hostile host with it.
