• Needing to Write

    It takes a wide range of skills to be a scientist. Besides my mathematical, coding, and statistical skills, I need to be a good writer and communicator. Like everything, I need to practice my writing and editing skills. So, I will publish a new idea every week. It may be a blog post, code documentation, a couple paragraphs of an upcoming paper, or something else. With this repetition, I hope to build both my writing skills and a great editing workflow.

  • TypeError from numpy, pandas, and linear algebra

    I was working with some data. I put it into a pandas DataFrame like many data scientists. I built the DataFrame up row by row because sometimes data is not packaged nicely.

    I then tried to plot the resulting data with seaborn’s regplot1 and got an nasty TypeError:

    TypeError: No loop matching the specified signature and casting was found for ufunc svd_n_s 

    In the trace back this is coming from some deep level in numpy’s linear algebra modules. I tried both the default and robust=True so the issue was not the specific numpy routine since statsmodels also had an issue.

    Finally after many attempts at searching for a solution I found this . . .

  • Jupiter's Great Red Spot [Link]

    NASA’s Juno spacecraft has a camera called JunoCam. It’s main purpose it to take pictures of Jupiter up-close and personal for the whole world to see. It recently [took images] of the Great Red Spot.

    The Great Red Spot has inspired and perplexed people ever since we first saw it. Juno, with its eight science instruments, is now providing us with the most information we have ever had on this phenomenon. Hopefully soon we will hear what scientist have newly discovered about this strange extraterrestrial storm.

    If this excites you, Juno invites the public to participate in the Juno mission. You can find out more on their website.

  • Differences Between Men and Women Are Vastly Exaggerated [Link]

    There are many biases peddled by our society.

    If you don’t see bias there, try this: when teachers know students’ names, boys do better on math tests. Yet when grading is anonymous, girls do better on math tests. And before a math test, reminding college students of their gender leads girls to perform 43% worse than boys. But if you just call it a problem-solving test, the gender gap in performance disappears.

    Biases affect men too. Women are stereotyped as more empathetic, and they do score higher than men when you test the ability to read other people’s thoughts and feelings. But if you don’t introduce it as an empathy test, the gender gap vanishes.

    Here is a great article discussing difference seen between the genders and how they are extrinsic rather than intrinsic.

    As an aside, I feel like the comment that “men feel . . .

  • Dyslexia [Link]

    I have dyslexia. One of the hardest parts of any disability is explaining how it effects you to others. Many people think of a visual flipping of letters when they hear dyslexia, but that is not how it effect most people. This post by the new tutoring service Clark, had a great quote.

    Differences can be seen in the brain’s development of those who have dyslexia and those who do not. The condition is commonly misunderstood as a visual impairment that results in the jumbling and reversal of letters. However, dyslexia is not visually-based. Instead, dyslexia is a processing issue that affects how the brain interprets information. Researchers have found that the condition is neurobiological in origin, stemming from a physical difference in the brains of those who suffer from it. MIT and Boston University neuroscientists recently identified a deficiency in a brain mechanism related to processing sensory . . .

  • Secure & Easy SSH on macOS Sierra [Link]

    Apple added a few non-standard interaction between SSH Agent and there own Keychain. This gave a great default of strong public-key cryptography with the convenience of not needing to enter a password all the time. But with macOS Sierra (10.12) the defaults changed[^defualts]. It took some time for people to figure out what was happening, but finally after 7 months, Bart Busschots explains how to reset the defaults and regain the old balance of security and convenience.

    For more information on SSH, I recommend the Bart’s Taming the Terminal parts 29 through 33.

  • America, the Church, and Discrimination

    America is called the land of the free. Why is the Church not also called the land of the free?

    The Bill of Rights is a revolutionary document that protects citizens and limits government. After the Civil War, our nation knew that we had a major discrimination problem, we wrote three new constitutional amendments that re-proclaimed our desire for liberty for all. Common place today is an anti-discrimination clause for businesses and organizations.

    There is a website that connects nonprofit organizations with software and hardware donations and not surprisingly they say that these nonprofits must comply with the website’s anti-discrimination policy. I love that! If you are advocating for reading to kids, then your staff promotions should not be made with regard to gender or sexual orientation. If you are helping families remove lead-based paint, your leaders should not be chosen because of their religion or national origin.
