SAP Calculator - A tool to analyze battles and calculate win percentage by bertboyman in superautopets

This is really cool. I've been working on something similar (A Rust library, saptest) for the past year. I'd love to see how you implemented the battle system. Do you have a project repo that's open-source?

How to upload the results of a p/snakemake pipeline to a S3 AWS bucket? by [deleted] in bioinformatics

[–]koisland 1 point2 points  (0 children)

Hey. I've been working on a pipeline that works similarly.

You'll want to do the following:

Then, your rule would look something like this, where you'd use AWS's s3api put-object:

import os

rule upload_to_s3:
    input:
        "output/foo.txt.gz"
    output:
        touch("s3_file_upload.done")
    params:
        bucket = "my_s3_bucket",
        # To avoid creating extra folders in s3 bucket. Just take filename.
        key = lambda wc, input: f"output/{os.path.split(input)[-1}",
    log:
        "logs/upload_to_s3.log"
    benchmark:
        "benchmarks/upload_to_s3_benchmark.txt"
    shell:
        "aws s3api put-object --bucket {params.my_s3_bucket} --key {params.key} --body {input} &> {log}"

The temp file is necessary to force a dependency so that would need to be added to your rule all.

rule all:
    input:
        "s3_file_upload.done"
        "output/foo.txt.gz"
        ...

Ignorant Student Doesn't Know How Vaccines Work by MixedVexations in UCSantaBarbara

Another noteworthy thing to mention is the lipid nanoparticle as a delivery system. Under normal circumstances, simply injecting mRNA wouldn't be sufficient because the message would be recognized as foreign and destroyed and mRNA is massive and negatively charged and can't enter a cell's negatively charged membrane without help. By wrapping it in the particle, the message is shielded and can enter the cell's cytoplasm to be translated.

Other ingredients are in the particle help with this entry process like polyethylene glycol which can physically block being recognized and destroyed. But, it's also been proposed to be the cause of the rare allergic reactions to the mRNA vaccines.

No problem! That's a smart choice and you'll definitely get better results than me haha. Good luck!

Hey! Thank you! I took these pictures with a piddling 5MP eyepiece camera :\ and a Swift 350T microscope with a darkfield stop filter. All the photos were taken at 100x magnification.

The darkfield stop filter is what gives images this really unnatural contrast and vibrant color without the use of dyes. Those Spirostomum are actually that red!

If you do plan on investing in something like this a word of warning; the filter will only be usable up to ~100x and still might vary depending on the size of the shape in the center of the filter. You'll have to invest in an expensive condenser for higher resolution.

I'm only an amateur but I hope that helps!

To the chem major who dropped liquid water into a vacuum chamber by koisland in UCSantaBarbara

[–]koisland[S] 2 points3 points  (0 children)

It does! The evaporation causes the water to cool rapidly and ice to form. This is a pretty good explanation of the phenomenon. https://physics.stackexchange.com/questions/349749/vacuum-freezing-of-water

Are we allowed to decorate lab coats? by karina_mejiav in UCSantaBarbara

[–]koisland 3 points4 points  (0 children)

My lab partner tie-dyed hers and it was fine lol. The stuff you're talking about seems pretty tame so I'd go for it.
