In fact, many new Pythonistas might assume that readlines would return an iterator (many built-in functions return iterators after all). This use case for list is really just a variation of the last two, but this is an important enough concept that it's worth repeating in 3 different ...
This means that the code depends on module_x, but that module isn’t installed in the current Python environment, creating a broken dependency. Modules like module_x can be manually installed using pip. For example, say you’re trying to run an application that uses pandas, but you don’...
Pickle in Python is primarily used in serializing and deserializing a Python object structure. In other words, it’s the process of converting a Python object into a byte stream to store it in a file/database, maintain program state across sessions, or transport data over the network. The ...

Both bias and variance are forms of prediction error in machine learning. Typically, we can reduce error from bias but might increase error from variance as a result, or vice versa. This trade-off between too simple (high bias) vs. too complex (high variance) is a key concept in statisti...
Heartbleed is a serious vulnerability discovered in the openssl open source software component in April 2014. This article is a deep dive on Heartbleed and its broader implications for application security: Heartbleed is described in detail. A proof-of-concept test environment is presented. An exploi...
Git computes the hash and uses this value for the object's name. The object is put into a directory matching the first two characters of its hash. The rest of the hash is used as the file name for that object. Git stores each revision of a file as a unique blob. The relationships ...
There were four quadrants of how to respond to a close Overall a very enjoyable book。 Here are some notes I took:1。 Richard Feynman was a bit of an odd duck。 I've read Surely You're Joking, Mr。 Feynman。 Even so, I liked the idea that he was unconventional and that there are...
I was tested to see if I could drive a clutch on the hills of San Francisco as I was being followed by my parents. I learned simple lessons by simple mistakes. I learned with tough love and accountability. Somewhere in the mix, I grasped the concept that it was not always about you....
