Out of the box, any M.2 NVMe SSDs connected to the Dell OptiPlex 3060 runs at PCIe Gen 2.0 speeds (Max 5 GT/s; 2 GB/s) so the speed tests look like this:
However, after this BIOS mod, the SSD can reach PCIe Gen 3.0 speeds (Max 8 GT/s; 3.9 GB/s) so the speed tests look like this:
Structured logs are way better than normal logs for a whole bunch of reasons, but they can sometimes be a pain to read in the shell. Take this logline for example:
{"erlang_pid":"#PID<0.1584.0>","level":"error","message":"Got error when retry: :econnrefused, will retry after 1535ms. Have retried 2 times, :infinity times left.","module":"","release":"c2ef629cb357c136f529abec997426d6d58de485","timestamp":"2019-12-17T19:22:11.164Z"}This format is hard for a human to parse. How about this format instead?
error | 2019-12-17T19:21:02.944Z | Got error when retry: :econnrefused, will retry after 1648ms. Have retried 2 times, :infinity times left.

General caution: Chrome OS is a secure OS by design, but this has at least one key consequence. If you change your Google account password, you will still be required to enter the old password the next time you access each Chrome OS device. Devices are encrypted with that password, so the OS needs to decrypt using the old password then re-encrypt using the new one. If you forget your old password you will lose access to your Chrome OS device data. As always, make sure you keep backups up to date.
If you have multiple Chrome OS accounts (Say, work and play), you can quickly sitch between them without logging out:

Many different applications claim to support regular expressions. But what does that even mean?
Well there are lots of different regular expression engines, and they all have different feature sets and different time-space efficiencies.
