History of The Entire World in 20 Minutes

I saw a critical (academic, not trolling) review of this in The Nerdist; however, it is widely watched by my students and popular.  That makes it good enough for a watch for me, and anyone.  Get it? 

Makes me think about what elements I include on a daily basis.

Free Online Programming & Computer Science Courses You Can Start in April

Dhawal Shah, founder of Class Central compiled this list of over 515 such free online courses that you can start this month. For this, he leveraged Class Central’s database of over 7,000 courses.  https://medium.freecodecamp.com/515-free-online-programming-computer-science-courses-you-can-start-in-april-8b0ce1817d61

These courses are sorted based on their difficulty level:

  • Beginner
  • Intermediate
  • Advanced

Many of these courses are completely self-paced. The rest will start at various times later this month. You can find complete lists of the technology-related courses starting later in 2017 on our Computer Science and Programming subject pages.

Should I Learn and Use a Raspberry Pi or Arduino Uno?

Yes

Why?  Which one? There is a short post at Make: reviewing these in general.  NOTE: kits, details, etc… are on the post, read it there, the information below is just to ensure it remains available for students.  Also, the article is over a year old

Here at Make: we see new, ingenious projects from our community every day. Many of these are made possible by the use of development boards. However, if you’re new to the subject, it can be confusing to parse out the differences between boards and the advantages of using one over another.

We’ve created this super simple guide to help you get started. Then, when you’re ready check out Arduino Uno and Raspberry Pi Starter Kits, which come with all the goodies you need for your inaugural projects. Not sure you want all those peripherals yet? Start with the essentials: Grab the board of your choice and bring yourself up to speed with our Getting Started With series for Arduino and for Raspberry Pi.

What is the difference between the two?

An Arduino is a microcontroller motherboard. A microcontroller is a simple computer that can run one program at a time, over and over again. It is very easy to use.

A Raspberry Pi is a general-purpose computer, usually with a Linux operating system, and the ability to run multiple programs. It is more complicated to use than an Arduino.

What would I use each for?

An Arduino board is best used for simple repetitive tasks: opening and closing a garage door, reading the outside temperature and reporting it to Twitter, driving a simple robot.

Raspberry Pi is best used when you need a full-fledged computer: driving a more complicated robot, performing multiple tasks, doing intense calculations (as for Bitcoin or encryption)

Is there a simple rule of thumb to help me decide?

Yes, there is! Think about what you want your project to do. If you can describe it with less than two ‘and’s, get an Arduino. If you need more than two ‘and’s, get a Raspberry Pi.

Examples:
“I want to monitor my plants and have them Tweet me when they need water.” That can best be done by an Arduino.

“I want to monitor my plants and have them Tweet me when they need water and check the National Weather Service, and if the forecast is for fair weather, turn on the irrigation system and if the forecast is for rain, do nothing.” That would best be handled by a Raspberry Pi.

Isn’t that rule of thumb oversimplifying what is actually a much more complex issue?

Yes. That’s what a rule of thumb is.

Look, this is confusing! Just tell me which one I should buy!

An Arduino. It’s a system designed for beginners.

650 Prompts for Narrative and Personal Writing

This is an amazing PDF of all 650 prompts from this NYTimes article!

Every school day since 2009 we’ve asked students a question based on an article in The New York Times.

Now, seven years later, and in honor of the Oct. 20 National Day on Writing, we’ve collected 650 of them that invite narrative and personal writing and listed them by category below. Consider it an update of a previous post, and a companion to the list of 301 argumentative writing prompts we published in 2015.
