How-To: Create a free Apple developer account for sideloading apps | 9to5Mac

Posted by jpluimers on 2017/02/16

Interesting: Starting with Xcode 7, Apple made it possible to sideload apps on the iPhone, iPad, and Apple TV using a free Apple ID. Although a paid developer account is still required to deploy apps to the App…: How-To: Create a free Apple developer account for sideloading apps | 9to5Mac

Ken Thompson – quotes – Reflections on Trust

Posted by jpluimers on 2016/12/21

Some of the Ken Thompson – Wikiquote entries come from a great 1983 ACM Turing Award Acceptance Lecture “Reflections on Trusting Trust”.

That lecture used to be on

But it isn’t, and it’s not in the WayBack machine and neither in the Google Cache because of the robots.txt. Historic link rot galore!

The lecture is about compiler viruses and viruses actually did this at least a few times: Delphi in the 2009 and to XCode in 2015.

A few nice links from ACM Classic: Reflections on Trusting Trust – Google Groups though:

And archived versions of (I hope accurate) copies of the article:

Finally I found a PDF copy of the original ACM prints that Greg Ganger of Electrical and Computer Engineering at Carnegie Mellon University has online. It’s archived too.

`xcode-select –install` required for OS X 10.9 Xcode command-line tools (like `zlib-devel`)

Posted by jpluimers on 2016/11/16

Hopefully this was a one time oversight from Apple, but on OS X 10.9 (Mavericks) the Xcode command-line tools cannot be installed from the Xcode Preferences pane.

You have to install them from the command-line:

xcode-select --install

There is one catch though: it might fail as you first have to start Xcode once and accept the license agreement.

You need them for instance when playing with zlib-devel (for instance when creating your own openssl builds).

Installing Python on Mac OS X — The Hitchhiker’s Guide to Python

Posted by jpluimers on 2016/10/11

Interesting, as I thought Mac OS X Yosemite and up – having Python installed – would also keep Python up-to-date, but they don’t.


Installing Python on Mac OS X

The latest version of Mac OS X, Yosemite, comes with Python 2.7 out of the box.

The version of Python that ships with OS X is great for learning but it’s not good for development. The version shipped with OS X may be out of date from the official current Python release, which is considered the stable production version.

Builds ChaCha20 version of openssl on Mac OS X static without dylib for use with

Posted by jpluimers on 2016/08/17

A while ago, [WayBack] needed Darwin binaries (for OS X): Supply Darwin binaries + install documentation · Issue #127 · drwetter/ [WayBack]

So I created the small Bourne shell (sh) script below to deliver them.

It allows me to update these gists:

The build script itself is in a gist as well: [WayBack]

It helped me to contribute to these issues:

Not all of these binaries are in [WayBack] as it makes the repository too bloated. Some (including non-OSX builds made by others) are here:

Eventually the script might get merged into [WayBack] as there is a Darwin switch in this commit: [WayBack]
