Recommendation: Shell Fu and Git at memrise

As you know I’ve followed some basic command line courses not were they only basic, the commands never stuck in my brain null

Memrise has an excellent command line course called Shell Fu created by Adam Chainz, who is also a web developer at memrise. This course not only learns you the command line but it also, as the name of the site already indicates null helps you memorizing the commands.

The other course I highly recommend is the Git course, created by shamgar. In case you wonder what Git is, wikipedia explains it rather well:

In software development, Git (/ɡɪt/) is a distributed revision control and source code management (SCM) system with an emphasis on speed.Initially designed and developed by Linus Torvalds for Linux kernel development, Git has since been adopted by many other projects.

Every Git working directory is a full-fledged repository with complete history and full revision tracking capabilities, not dependent on network access or a central server.

So if you have ambitions in programming, learning Git is a must null

But the course I am totally smitten with at memrise is, the prime factorization course null I joined memrise at the 29th of April to do the Shell Fu course, which I still do daily btw. Yet I control the leadersboards at memrise when it comes to prime factorization null

What can I say, I just love to break numbers into primes null

A learn to code commercial

I agree with this part:

Knowing how to code is like knowing how to read and write was in medieval times.

I disagree with what is written here:

You can certainly get along without it, but you do so by living in ignorance of many of the wonders around you.

Being able to program is becoming important in the entire STEM fields. I do think that in other fields you can now certainly get along without it, but it won’t be too long before not knowing how to code will have the same devastating effect as it has being not able to read and write in these times. Yeah, I know it is rather dark outlook on the future null

I once heard a dean of an Indian University, where girls and boys were going to separate classes, say:

“It’s the hand that rocks the cradle that rules the world”

She was defending this outright medieval thing of separating boys and girls   I of course disagree with this one too. I think it is the “hands” that know how to code that will rule the world.

Just take a look at Anonymous.

My own Python challenge

Earlier this morning while working on my math, I had to calculate the LCM (Least Common Multiple) and I was thinking I should write a Python script for it. Just for fun. Yeah “fun” I probably am  going insane null

There is no need to point out the math module in Python,  which probably has a function called LCM.

So I typed what I know right now:

While advancing in Python, I will improve this script null (I know that I’ve written a loop and that I should make it stop after the first hit, otherwise it will go on forever null)

People, tell me WTF is WRONG with me??!!!?????

I used to be a doodler, I loved to doodle geometric shapes in all dimensions, mostly triangles and squares. In my doodles I used them to create something  like machines (cranes being my favorite) or transformers. But now I like do something else a lot more, I love making prime factorization trees. I just love it null the bigger the number the better null

I gave myself a lot of thought, on why on Earth I would like to do something like this. I came up with this

It’s just a serene, peaceful thing to do.

Is THIS the first sign of insanity? Seriously, just when you think you’ve seen it all when it comes to knowing yourself, you discover something like this null

For the people who wonder what a factor tree is, here is one:

So all you “psychologists” out there,  eat you heart out and tell me null
