My dudes, if you can learn network protocols and syntax/idiom for (multiple) programming languages, etc. you can also learn human communication.

The number of likes and retweets on this is scary. It was a joke. If you have people on your team who you consider to be "dead weight", maybe have a look at why? Like, how you are not supporting them properly? Are they not in the right place to add value. Is their value not seen?

Just wait until the people opposing "cancel culture" find out about people of certain races, genders, etc not getting hired for jobs / not treated by medical professionals. They should be outraged.

Friend: You don't have to work at all?
Me: Well... I was asked to write this article. And am organizing this conference. And I have a talk in 2 weeks that I need to prep.... And oh yeah, sewing a quilt.
Also me: Why am I so tired?

Person: how does programming work?
Programmer: well you type & you delete. You rethink. Then you do 187 min of research & correct it. You reread & wonder if you have a grasp of <programming language>. Then you revise
P: then you’re done?
Prog: then you move to the next method

Sometimes the problem isn't a technical one to be solved with tool, but rather a communication problem that should be solved by talking to each other.

Today in correlation != causation:
Want to live longer? Try going to the opera. Researchers in Britain have found that people who reported going to a museum or concert even once a year lived longer than those who didn’t.

Firing based on LOC alone is obviously not great, but it has some value. I know no one wants to hear this but there wasn’t a lot of time and huge cuts had to be made. LOC will measure some form of productivity across hundreds/thousands of individual contributors.

Once more for the people in the back...
New research finds that young girls and boys have "indistinguishable" math abilities — contradicting the idea that men largely dominate STEM fields because their brains are wired that way.

Tfw you get a message from a friend the day after your talk about how a test that was supposed to fail when she changed the functionality didn't, because the original test wasn't implemented correctly.

I think the point is they're not treated fairly. They are beeing given an advantage not given to others. They want *everyone* to be treated fairly, otherwise it's still unfair.

People on social media spouting statistics like: only a very small amount of children died of cobid and they had underlying conditions.
Yes, my 4yo nephew has underlying conditions and I'd prefer for him to not become one of those statistics.

"Exploratory testing requires skilled and curious testers, who are comfortable with learning about the software and coming up with new test designs during a session."
Excellent blogpost!
