  • Back when Perl was the language of choice for bioinformatics, I found a huge performance boost pre-processing large (~1Tb) text files using built in unix tools like sed and awk with regex. So while it might take me a full hour to peck out the correct incantation, the task would then run in an hour, compared to four hours or more for the same task using Perl.

    So many pipes…




  • It’s great as a mental prosthetic. When I am tackling a new complex topic like say a new cloud platform I’m learning, i can test my understanding of the implications of a change to the console settings. I tell it what i think and ask it to check my understanding. Really speeds up my learning, but I don’t rely on it exclusively. I will write my own dang emails, thank you.











  • In addition, in order to get useful fibers, plants are sown at a density of at least several hundred seeds per square meter. They stretch to 2-3 meters tall trying to win the race to the sunlight. Stalks of plants grown in the typical indoor grow way are only good as very low grade biomass for methane digestion or as chips that might serve in hemplime or hempcrete. An insignificant market so far as these technologies are still going through the regulatory processes to be used more widely.

    There are effective dual cropping systems that can yield cannabinoids from flower and get useful fiber but it is not common yet either.

    Your systemd file looks ok, but I think it’s doing exactly what you are telling it.

    The solution may lie in the backup.service. Is that code you can modify? The OnCalendar=weekly doesn’t specify when in the week the service should run so that config may be vague.

    If I understand the desired function here, you will need the service up all the time. It will just wait politely and occasionally run the specific backup script. It’s up to the backup script to determine when the last backup was made and either exit early because it hasn’t been a week or run the backup and reset a flag file.

    At least that’s the approach I would take. Systemd is a very vigilant, but very stupid, service manager. It just watches and triggers services based on just a few criteria. Any logic more complex needs to go in the service itself.
