Essence of linear algebra [1] , in 3blue1brown youtube channel totally changed my perspective on Linear Algebra. One of the best channels in YouTube I have seen so far. He makes his videos using the animation engine [2] he built himself.

That whole channel is amazing! I can start just listing all the videos by virtue of picking out awesome ones, but check out the one he did on Euler's formula[1]. Blew my mind.

I didn't know pretty much anything about linear algebra, but by watching the series, I felt deep enlightenment. Also, the videos they have done about topology really made me believe everything is, in essence, geometry.

> What really would help me - and i struggle with this - if i have clear priorities in my head - what I want to achieve in the 'extra time' that I have got. The clearer the goal, better the results.

I suffered with the same thing. I started using dynalist (https://dynalist.io/) to list down whenever i felt like i wanted to do something. Later when i have free time, i just go to the list and see what i can finish in the time i've got. It offers a very intuitive interface to map/organise ideas. An alternative to it is Workflowy (https://workflowy.com/).

Windows is case INsensitive. Just merged two repositories accidentally because of that.

so is OS X by default:

     $ cd /tmp
     $ mkdir Abc
     $ mkdir abC
     mkdir: abC: File exists

>The phone comes with a 3.5mm to Lightning adapter, so you can continue to use your existing headphones.

What if I want to use my headphones while charging my phone?

Quite a few companies sell adapters that allow for this.

So now you need two dongles for one set of earphones.

And how is the quality of the DAC in that adapter?

Sure sounds great!

Try disabling adblock/ghostery

That worked.

Not sure, but this should make the kernel implementation simple. Any low memory (RAM and Flash) microcontroller can take advantage of this.

You should credit AMD for introducing AMD64/x86_64. Without that backward compatibility wouldn't have been possible.

Meal planning tool - Nice. I would be very interested to use if it could also give food recipes based on stuffs available with me.
