Where do you see yourself in five years? What’s your five year plan? These are variations of a common job interview question. I don’t like that question.

Occasionally when I close the lid on my laptop, it doesn’t come back. The hard drive light is blinking and it shows signs of life like the caps lock light lighting when I hit the key.

It’s probably not news to you that the hot trend in computing in 2021 is moving from on-premise computing to cloud computing. And that’s been a hot trend for several years. But what comes after cloud? What will replace cloud? It’s possible to predict what it will look like–just not the specifics.
My friend was building a new system. And like many new builds when you haven’t done one in a while, not everything went as smoothly as it could have. Here’s how he solved a phantom CPU fan error.
I frequently get data in CSV or Excel format, which I then have to use to deploy a vulnerability management solution like Tenable or Qualys. I use Pandas to process this data, which usually involves iterating each row of the dataframe in Pandas. It abuses Pandas. But it works. Yes, it’s a hack. I don’t care.
