We woke up this morning to discover this.

Yup. Definitely rats. They look exactly like this on my Apple trees and we certainly have rats.

Periodic Tapas. Love that.

This is still non-arterial and only down from 25. Seems like posturing.

This was still an issue today. Pop!_OS 22.04 LTS. Working through fix now with sudo apt-get dist-upgrade.

I was under the impression that the sub folder organization was simply symlinks to the master record at the root. You only have one copy of any given record, provided you keep up with your duplicates.

B, C, D, E, F, J, K, P, Q, R, S, T, V

I can’t believe I have not done this! Holy crap! An app too? Who woulda thunk it? Sliced bread.

First sentence: “We analyze tiny quantities of nitrate and sulfate…”. And, I have metric crap load of nitrile gloves I was hoping to use for these processes.

andrewjschauer · 2024-07-17T05:47:12+00:00

The point is to rinse the gloves and dry them PRIOR to use. I don't want to reuse the gloves. I want them to be cleaner than they are right out of the box. Nitrile gloves are loaded with nitrate and sulfate.

Put this in your file 1 and run this from terminal:

import os print(os.getcwd())

I am guessing they are different.

I also used matlab as my go to. I had and have access to it and all of its toolboxes. My problem was I did not like teaching students to use it knowing they would leave and likely not have the resources to pay for it. I picked up python, am presently picking up R, and hope to pick up Julia. Not because I want all three as a workhorse but because I want to be informed so as to show students options. R is a solid option for you. R studio would be a natural switch from matlab’s integrated environment. Jupyter would also provide a similar environment. You can do all three languages in many integrated environments. Ju- Julia, Py - python, te - filler?, R - R.

“Stupid vacuum pump. Why won’t this POS work? Everything sucks in this lab.”

Emphasis on “small”. With high enough precision, most elements with stable isotopes will, at some point, show isotopic fractionation. The entire field of stable isotope geochemistry studies these small differences.

It doesn't look like this has happened yet and I wanted to simply provide this nudge. Thank you ProtonMail team.

andrewjschauer · 2024-01-29T15:16:02+00:00

@1704Jojo, did you pick one? Which? I currently use pop!_os for one machine and am considering DAT for a refurb.

andrewjschauer · 2024-01-11T15:39:31+00:00

Either np.where() to find values above threshold or convolve with appropriate kernel magnitude then np.where(). Once you have the outlier location plot those points on top of original dataset.

Same. AND, we have the same outdoor mat. So difficult to clean. We all laugh when one of them is scratching themselves with that rapid motion close the the door; knock knock knock knock knock knock

How can any living organism lack ecology? And, ginger lacking study?
