My brain really hurt after work today,

[Doc_Lobster]

and now I am numbing it with wine.

It was an intense thinking day.

I wish I had those. My toughest decision today was whether to order yellow or pastel colored post its.

On a Friday? That's bullshit (not bullhorn, stupid iPhone!)

[Doc_Lobster]

I had to write a program that can simulate randomly distributed clusters of data points with minimal user inputs. I was kind of stuck on what to use for the covariance matrices (because I don't want them to be the same for each cluster, too simplistic). Turns out that the eigenvalues of the covariance matrix are the squares of the standard deviation of the distance from the centroid in each dimension of the cluster. If I use a distribution of standard deviations and a generic set of eigenvectors, I can make several unique covariance matrices. Walla!

Then I had one of the grad students in my office trying to get me to "just" include a simulation of blah blah blah (super ass complicated shit) because that would be great. I hate it when people say "can't you just do this thing?" without any conception of how difficult it would actually be.

Daddy, I do not want a boat like this.

I like post its.

I can't see animated gifs using the app.

What is he doing?

In my dream I knew the formula for glue!

He is rubbing his eyes because he is overwhelmed and frustrated

[Doc_Lobster]

And that is how I felt today.

[ProfessorArtNerd]

Uhhhhhhh. Whut?

[hubes]

Just you describing your day made my brain hurt.

[Doc_Lobster]

So you see why I need to drink!?

This is why I had to start making my own wine. It was becoming the biggest line item in my budget.

Once upon a time I thought I was smart

Then I read your post.

Now I know better
