  You probably use the cd command on Linux every day. But did you know that there are some hacks that let you improve your experience while navigating different directories? After applying these tips, I'm able to change directories without worry of making mistakes.

• Jon Chiappetta: Split VPN Tunnelling and Routing Based on Packet Protocol and Port for Improved Network Performance and App Compatibility

  So I’ve been running a highly modified version of OpenVPN and speed and performance have been pretty good overall, however, I noticed that some very few apps would use a custom UDP based API call for data transfer (Ring live video app) and the video would appear very choppy and blurry. I suspected this is because the multi-threaded version of OpenVPN does not preserve UDP packet ordering (whereas UDP protocols like QUIC seem to be more advanced and capable).

• University of Toronto ☛ I wish SSDs gave you CPU performance style metrics about their activity

  Having written this, I checked some of our SSDs (the ones I'm most interested in at the moment) and I see that our SATA SSDs do expose some of this information as (vendor specific) SMART attributes, with things like 'block erase count' and 'NAND GB written' to TLC or SLC (as well as the host write volume and so on stuff you'd expect). NVMe does this in a different way that doesn't have the sort of easy flexibility that SMART attributes do, so a random one of ours that I checked doesn't seem to provide this sort of lower level information.
