Controlling interdependent meso-nanosecond dynamics and ... - Science
Laser powder bed fusion is an additive manufacturing technique that laser-melts powder layer by layer to build a three-dimensional (3D) part. Khairallah et al. used experiments and a multiphysics model to determine the origin of the melt spatter and defect formation that degrade the properties of built parts (see the Perspective by Polonsky and Pollock).

How to remove nanosecond from file How can I remove nanosecond from every line in a file. data looks like filename is **test.csv** ip,time,name 1.1.1.1,2018-08-17 15:05:52:016469121,1.13.0-0007 1...
Try sed 's/:[[:digit:]]*,/,/' file ip,time,name 1.1.1.1,2018-08-17 15:05:52,1.13.0-0007 1.1.1.2,2018-08-17 15:05:52,1.13.0-0007 it will replace the last colon, following digits, and final comma with just the comma.

awk -F, 'BEGIN { OFS=FS=","; } { seconds=substr($1, index($1, ".")-2, 10); ms=substr(seconds, 7); seconds=substr(seconds, 1, 6); if (ms > 5000) seconds += 0.001; $1=sprintf("%s%6.3f", substr($1, 1, index($1, ".") - 2), seconds); print }' < input This simply brute-forces the timestamp fields out of t...

Data mile
The speed of light is 983571056 ft/s, or about one foot per nanosecond. If it were exactly one foot per nanosecond, and a target was one data mile away, then the radar return from that target would arrive 12 microseconds after wikipedia.org

Why debugfs doesn't show crtime in nanoseconds? I am using: debugfs -R 'stat <7473635>' /dev/sda7 to get the file creation time (`crtime`). Inode: 7473635 Type: regular Mode: 06...
It does show the timestamp (with nanoseconds precision) but _in hex_ ; it's the field after `crtime:`, e.g. in your output `0x55b65ebc:970fe7cc`. The part after the colon is the nanoseconds. This article gives more details and explains how to calculate the timestamp/nanoseconds. So, e.g. to convert ...

Determine file system timestamp precision File timestamps precision is limited to one second for EXT3, one microsecond for UFS, and one nanosecond for EXT4 (at least according to experience). Is there any way to deter...
As far as I know, there is no place that this information is stored on. It is coded into the filesystem. However, you can manually make a list of filesystems and the corresponding precision. I would use a `case` statement to test the filesystem id against your list of filesystems. You can make the d...
