@docm77 Go to bed, Doc!

Most grad students don't need another thing on the CV. They need more money so that they can do what they're already doing with less stress.

Financial worry is debilitating.

This was far and away the best thing I’ve read since Oct 7. Read every word https://t.co/MAJEMPCTII

@eric_j_thompson I feel the opposite! Last year I hated feeling like lucky frauds. This year I'm enjoying feeling like unlucky contenders. We'll get our due as the season progresses!

"Robustness of microbiome function" is a review we wrote to introduce potential mechanisms for functional robustness against environmental perturbations. (w/ amazing Yeonwoo @whatdoidohaha, @SeppeKuehnLab). Freely download thru this link until Nov 23rd.

Got some codes for the other place in case anybody else wants out!

@h_pan3 Lake Harriet Vet was one of the few places accepting new patients that I could find in south Minneapolis for a while. Just had my cat's teeth cleaned there although it wasn't super cheap.

As a data scientist I can only recommend Python, especially for web scraping (look up Beautiful Soup). But either can work if it means you get coding!

[Susi_Duran @Susi_Duran_]

I want to learn to scrape data and R. I have a choice to learn Python OR R first. Does it matter which one first? Or which one is best to learn first?

[Eric Johnson, Ph.D. @eJohnson643]

@johnnystantoniv We use Roll20, which works well enough!

[Eric Johnson, Ph.D. @eJohnson643]

@SeanBormanNFL I'm glad he got that first catch, but man was JJ open for the first down 5 yards away...

Thank you JGI and DOE for selecting our proposal of understanding soil microbiome's functional response to environmental change for the CSP24 program to do metagenomics sequencing of 10 Tbp! Highly recommend this grant to everyone!

@GeminiTayMC I've always had better luck using LogicalGeekBoy's setup. But in your setup, it might be that giving the villagers a space to walk off the beds makes it harder to consistently get the zombie/villager line of sight correct.

@kareem_carr This also makes concepts like the chain rule easier to understand!

[Eric Johnson, Ph.D. @eJohnson643]

@ScienceScottT This has been in my reading list! I'll have to bump it up top.

[Eric Johnson, Ph.D. @eJohnson643]

@ScienceScottT We show one way to get around this with EMBEDR! In the package, there's a scale-free implementation of t-SNE.

[Eric Johnson, Ph.D. @eJohnson643]

@ScienceScottT In any case, we *can* test the reasonableness of structures and clusters in embeddings using methods like scSHC (https://t.co/NmDu4GtrZ0) or EMBEDR (https://t.co/AFkgyRRUNr).

[Eric Johnson, Ph.D. @eJohnson643]

@ScienceScottT This is usually due to the fact that the default scale parameters in t-SNE (perplexity) and UMAP (n_neighbors) are inappropriately low. When you bump perplexity up to >100, this "overfitting" goes away. This example uses the code you provided.
