Understanding Apple silicon (lots of videos)

Yesterday, I posted an article positing that WeWork’s CEO might just be indirectly and accidentally responsible for drastically changing the processor industry:

What if WeWork’s jamoke CEO accidentally changed the processor industry?

The article got a record number of pageviews, and I got a number of emails and direct messages asking all sorts of questions about Arm chips, from “What makes Arm processors so different?” to “Has anyone seen an Arm-based Mac in action yet?”

Here are some videos that should provide lots of background material to better help you understand Arm chips and Apple’s move to their own custom silicon.

Let’s start with this CNET supercut of the parts of the WWDC keynote where Tim Cook and company talk about Apple’s transition from Intel chips to their own Arm-based ones:

This is Max Tech’s best guess as to what the Arm-based Mac release timeline will look like:

Many people have a take on what Apple’s move to Arm means. Here are CNET’s top 5 guesses:

Here’s a video from a year ago that asks “Is Intel in trouble? Is ARM the future?”. It’s worth watching for its history lesson about Arm:

Here’s a really quick (under 6 minutes) look at Arm CPUs:

Here’s a more hardcore explanation of how CPUs (in general) work:

CPUs used to be stand-alone things, but we’ve been migrating to SOCs (systems on a chip) for some time. Here’s an explainer:

This Gary Explains video explains the differences between Arm’s and Intel’s architectures:

Here’s a reminder from Computerphile that Arm design chips — they don’t make them. There’s a difference:

Here’s a treat: an unboxing of Apple’s “developer transition kit”, which registered Apple developers can apply to try out to test their apps on Apple silicon. It’s a Mac Mini powered by an Apple A12z chip, which is the same processor that drives the iPad Pro.

What if WeWork’s jamoke CEO accidentally changed the processor industry?

 

In order to understand this story, you need to be aware of this news item: Softbank is considering the options of selling outright, selling part of, or making a public offering of Arm, the British chip design firm behind the chips that power just about every smartphone, a whole lot of IoT devices (including the Raspberry Pi), a fair share of Chromebooks, and soon, Apple’s computers.

Softbank is considering this move because it needs the money. It has an activist investor that wants to see some changes, because it’s made some embarrassing investments leasing to considerable losses of both money ($16.5 billion for the financial year ending March 2020) and face.

One of those embarrassing losses is the fault of Adam Neumann, cofounder and CEO of WeWork, and the jamoke pictured at the top of this article. You may remember the story from last year, where the company — effectively a Regus pretending to be a Netflix — had to delay its IPO due to concerns about its pretend profitability and flaky, cult-of-personality non-leadership.

These concerns led investors to take a closer look at their numbers and Neumann’s aberrant behavior and business dealings. This in turn led to Neumann stepping down as CEO in September, SoftBank taking control of their investment, and paying Neumann $1.7 billion to leave the board.

Simply put, Neumann’s hijinks cost Softbank a lot of money, and they now have an investor putting serious pressure on them to sell off assets to raise cash. Arm could be one of those assets.

At the same time, there are a number of interesting developments where Arm chips are concerned…

At WWDC 2020, Apple announced that they were moving their computers off Intel x86 chips, whose notoriously bad design is really showing its age these days, and to their own custom Arm-based chips. (Arm has “standard” chips, but if you’re a big player, you can work with them to have them design custom chips for you.) The Arm-based processors in the current line of iPhones run circles around not just the processors in Samsung’s flagship phones, but also most laptops as well.

Any talk about what Arm chips will mean for Apple is all speculation right now, but if you want to hear some really good speculation, as well as a decent Arm vs. Intel discussion, check out episode 777 of This Week in Tech:

In that episode of This Week in Tech, host Leo Laporte and his panel agree that Windows PC OEMs will probably end up switching to Arm processors, and they’re not the only ones saying it.

Arm also had a moment in the sun on the mainframe front: The new holder of the title of “world’s fastest supercomputer”, the Fugaku, is powered by Arm chips.

There’s a pretty good chance that Arm will end up being the de facto chip design to rule them all in the 2020s — and their maker is up for sale. In fact, there’s an unnamed interested buyer. I have a guess, and I’m not the only person to have the same idea:

(In case you’re wondering: Apple had $245 billion in their cash reserves last year, and Softbank bought Arm for $32 billion a few years ago.)

Programming What I’m Up To

Computer Coach’s “Intro to Python Coding” course (taught by Yours Truly) starts tonight!

The online Intro to Python Coding course that I’m teaching on behalf of Tampa Bay’s own Computer Coach Training Center starts tonight at 6:00 p.m.. For the next five weeks, on Monday and Wednesday evenings from 6:00 to 10:00, I’ll be leading a class of Python learners through “code along with me” exercises in the Python programming language.

The format of the course will be pretty much the same as the one I use at Tampa iOS Meetup, where I lead the group through a “code along with me” exercise. I project what’s on my computer on the big screen, and everyone follows along, entering the code as I explain what’s happening.

Since Python has a REPL (Read-Evaluate-Print Loop), I can also have the class go through some exercises and try little coding challenges. It will be a “learn by doing” kind of class.

The main textbooks for the course (which will be provided to students) are Python Crash Course, 2nd Edition…

Book cover: “Python Crash Course, 2nd edition: A Hands-On, Project-Based Introduction to Programming”

…and Automate the Boring Stuff with Python, 2nd edition (which is free to read online):

Book cover: “Automate the Boring Stuff with Python, 2nd edition: Practical Programming for Total Beginners”In order to minimize confusion, we’ll all use the same tools in the course, namely the Anaconda Individual Edition distribution of Python 3.7 and associated tools…Logo: Anaconda…and Visual Studio Code:

Logo: Visual Studio CodeBoth are available free of charge, and run on macOS, Windows, and Linux.

It’ll be fun! Watch this space; I’ll post some snippets from the course as it progresses.

Interested in signing up? Visit Computer Coach’s site and speak to them. Don’t dawdle — it starts tonight!

Two printer posts; one printer truth

I saw these two posts about printers this morning — one on Twitter, the other on Facebook, in a neighborhood forum where someone was asking for office equipment and furniture that people were no longer using:

I find that I use our home printer about once a year, typically for printing a letter that I need to enclose with a paper form that I’m sending via snail mail.

How often do you use your printer at home (if you have one) these days?

The course description

Photo: Woman’s hands typing on Mac laptop.

This is an introduction to the Python programming language. Now in the top 10 programming languages according to the TIOBE Programming Language Index, it is versatile enough to have a wide array of uses, from simple scripting to powering Instagram, Spotify, Netflix, Dropbox, and more. Its combination of simplicity and vast scientific and math libraries have made it the preferred programming language for data science and machine learning. If you’re looking for a first programming language, Python is an excellent choice.

 

This is not a passive course! This isn’t the kind of course where the instructor lectures over slides while you take notes (or pretend to take notes while surfing the web or checking your social media feeds). In this course, you’ll be actively taking part in the learning process, entering code, experimenting, making mistakes, correcting those mistakes, and producing working applications. You will learn by doing. At the end of each session, you’ll have a collection of little Python programs that you wrote, and which you can use as the basis for your own work.

The course will start at the most basic level by walking you through the process of downloading and installing the necessary tools to start Python programming. From there, you’ll learn the building blocks of the Python programming language:

  • Control structures that determine what your programs do,
  • Data structures to store the information that your programs act on,
  • Functions and objects to organize your code, and
  • Using libraries as building blocks for your applications.

You’ll write all sorts of programs…

  • You’ll use Python in “immediate mode” to perform quick calculations (and you’ll sharpen your command-line skills in the process).
  • You’ll write scripts to simplify or automate tedious tasks.
  • You’ll build web applications.
  • And since it’s a networked, data-driven world where no application is an island, you’ll learn how to use Python to interact with web services and databases.

Better still, you’ll learn how to think like a programmer. You’ll learn how to look at a goal and learn how you could write a program to meet it, and how that program could be improved or enhanced. You’ll learn skills that will serve you well as you take up other programming languages, and even learn a little bit about the inner workings of computers, operating systems, and the internet.
