Books: Out of their Minds: The Lives and Discoveries of 15 Great Computer Scientists

I just finished reading Out of their Minds: The Lives and Discoveries of 15 Great Computer Scientists. In short, I liked it. I wouldn't say I liked it as much as, say, Coders at Work, however, I'm glad I read it. What I liked most about it was that it contains biographies from really early computer science pioneers such as Ada Lovelace, John von Neumann, John Backus, and John McCarthy. I know computer history after 1970 really well, but this book contains a lot of stuff from before 1970.

I jotted down a few interesting tidbits while I was reading the book. However, since I read the Kindle version of the book, I only have percentages, not page numbers. Anyway, I hope you're as entertained by some of these as I was.

John Backus, who lead the team that created Fortran at IBM, flunked out of college [2%]. He had a metal plate installed in his head [3%]. He disliked calculus but liked algebra [3%] (just like me!). These days, Backus is a proponent of functional programming [7%].

John von Neumann, who helped establish the fundamentals of computer architecture, thought that creating a programming language (i.e. Fortran) was a waste of time since programming wasn't a big problem [4%].

Ada Lovelace, who was the first programmer (not to mention, a girl!), was a gambler, an alcoholic, and a cocaine addict. She died of cancer at the age of 36. She is credited with inventing loops and subroutines [5%].

Fortran only had globals. Algol, which is considered an ancestor of C, added locals, thus permitting recursion [6%].

McCarthy, who designed Lisp, was born in 1927 to Communist party activists. He had an Irish, Catholic father and a Lithuanian, Jewish mother [8%]. McCarthy is the reason Algol had recursion [11%]. (I didn't know that C got recursion because of Lisp.)

Alan Kay, who did pioneering work on object-oriented programming and helped create Smalltalk, got thrown out of school for protesting the Jewish quota [15%].

Edsger W. Dijkstra, who did influential work on a lot of early computer science problems such as concurrency, did very well in school and wanted to turn programming into a respectable discipline [21%].

Fred Brooks, who wrote "The Mythical Man-Month", wrote this about iterative development:
In "The Mythical Man-Month" I said build one and throw it away. But that isn't what I say anymore. Now I say, build a minimal thing--get it out in the field and start getting feedback, and then add function to it incrementally. The waterfall model of specify, build, test is just plain wrong for software. The interaction with the user is crucial to developing the specification. You have to develop the specification as you build and test.

Yeah Fred Brooks! 100% agree.
BTW, if you haven't read "Soul of a New Machine", now would be a good time.

I need to read that. It's on my TODO list, and it's gotten 3 recommendations from my friends.

Drawing Sierpinski's Triangle in Minecraft Using Python

In his keynote at PyCon, Eben Upton, the Executive Director of the Rasberry Pi Foundation, mentioned that not only has Minecraft been ported to the Rasberry Pi, but you can even control it with Python. Since four of my kids are avid Minecraft fans, I figured this might be a good time to teach them to program using Python. So I started yesterday with the goal of programming something cool for Minecraft and then showing it off at the San Francisco Python Meetup in the evening.

The first problem that I faced was that I didn't have a Rasberry Pi. You can't hack Minecraft by just installing the Minecraft client. Speaking of which, I didn't have the Minecraft client installed either ;) My kids always play it on their Nexus 7s. I found an open source Minecraft server called Bukkit that "provides the means to extend the popular Minecraft multiplayer server." Then I found a plugin called RaspberryJuice that implements a subset of the Minecraft Pi modding API for Bukkit s…

Apple: iPad and Emacs

Someone asked my boss's buddy Art Medlar if he was going to buy an iPad. He said, "I figure as soon as it runs Emacs, that will be the sign to buy." I think he was just trying to be funny, but his statement is actually fairly profound.

It's well known that submitting iPhone and iPad applications for sale on Apple's store is a huge pain--even if they're free and open source. Apple is acting as a gatekeeper for what is and isn't allowed on your device. I heard that Apple would never allow a scripting language to be installed on your iPad because it would allow end users to run code that they hadn't verified. (I don't have a reference for this, but if you do, please post it below.) Emacs is mostly written in Emacs Lisp. Per Apple's policy, I don't think it'll ever be possible to run Emacs on the iPad.

Emacs was written by Richard Stallman, and it practically defines the Free Software movement (in a manner of speaking at least). Stal…

Creating Windows 10 Boot Media for a Lenovo Thinkpad T410 Using Only a Mac and a Linux Machine

TL;DR: Giovanni and I struggled trying to get Windows 10 installed on the Lenovo Thinkpad T410. We struggled a lot trying to create the installation media because we only had a Mac and a Linux machine to work with. Everytime we tried to boot the USB thumb drive, it just showed us a blinking cursor. At the end, we finally realized that Windows 10 wasn't supported on this laptop :-/I've heard that it took Thomas Edison 100 tries to figure out the right material to use as a lightbulb filament. Well, I'm no Thomas Edison, but I thought it might be noteworthy to document our attempts at getting it to boot off a USB thumb drive:Download the ISO. Attempt 1: Use Etcher. Etcher says it doesn't work for Windows. Attempt 2: Use Boot Camp Assistant. It doesn't have that feature anymore. Attempt 3: Use Disk Utility on a Mac. Erase a USB thumb drive: Format: ExFAT Scheme: GUID Partition Map Mount the ISO. Copy everything from the I…
