Have you ever caught yourself typing the same long Linux command several times and thinking, “There’s got to be a better way!” That happened to me. Over time, I realized aliases are the easiest way to fix that, turning long, complicated commands... #raspberrypi #linux

More work tonight on my precise clock project; most visibly, I added a 20x4 LCD display. The current date and time are displayed at the top; the second line shows the last clock correction applied, and the fourth line is overall estimated error.

![a picture of a messy workbench cluttered with small electronic bits and bobs, with a raspberry pi 4 front and center. there's a GT-U7 GPS module, which is kinda crappy tbh, but it has a PPS out, so it works well enough! that GPS is connected to 5v/Gnd/UART (for serial) /GPIO (for PPS) on the pi4 GPIO. there's also a 20x4 LCD showing the date and time, then
S[1] -0.000000157sec (stratum 1, last correction 157 nanoseconds)
L[*] PPS (locked to high-precision PPS source)
SATS[07] -342ns (7 satellites used for time fix, overall error estimate is -342 nanoseconds)
that last field, overall error estimate, includes estimated network dispersion time, so not only keeping precise time but also serving it out to local clients.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:245ryzg2mvhipesm7odi53s2/bafkreifzs4cvrwvrttfjeqc7vv7fo2d2wz2lcm363qvqrfof7hl6zi6ykq@jpeg)
