The Geeks way of checking what the outside wheather is like

No window? Listen for rain, wind, crickets, birds. If you're in a city, what sound do car tires make when they drive by? Sound like wet streets, or snow slush?
Maybe you could get some info on how much condensation forms on a glass of cold water. But that might just be measuring the inside temp.
Reminds me of the MIT question of how to find the height of a building with a barometer. The best answer was find the building superintendent and offer to trade the expensive barometer for the height of the building.
You might even be able to come up with a numerical guesstimate. Theoretically, a properly designed AC system is sized to run 100% of the time during the hottest weather. And obviously 0% if it's cool enough outside.
Or just look around the office and note how people are dressed, whether there are coats on people's chairs, how heavy those coats are, and whether you see any umbrellas lying around.
This is why, when I want to know what the weather is, I use the vast array of sensors that the US government has paid for, and the expertise of meteorologists. Just google it.
If you want to parse it, get the raw METAR string and parse individual components such as temperature. Not a fun thing to do though.

That said, this native American English speaker says that "Geeks" can be capitalized, but the rest of the title needs to be "title cased" as well: "The Geek's Way of Checking What the Weather..." Or it can all just be lower-cased ("The geek's way of..."). But mixed case as TFA has it is arguably wrong.
Finally, to answer your question succinctly: there normally isn't a reason to capitalize "geeks" unless it's in the title of an article or book (as it is above).
That said, yes, some sloppy editing as well. Not that I'd ever do schu a thing....
