josso··on Blind Apple engineer is transforming the tech world at only 22
In System Preferences » Keyboard » Shortcuts you need to have enabled Full Keyboard Access. The shortcut to toggle it is (fn-)Control-F7. After that you can tab through all controls and navigate to the Mouse Keys checkbox and check that.

No, they only streamed a single track live.
josso··on Google has started a video series on machine learning and I can understand it
I also recommend Welch Labs’ Neural Network Demystified-series[0]. It is a combination of the Coursera course and the YouTube videos. It get’s into some of the math, while still keeping it basic.

josso··on Manual arbitrary code injection in Super Mario World [video]
Really impressive job by SethBling and p4plus2.

The notes for how to replicate it can also be found in this Google Document[1] and the payload for the injected game itself is also available[2].

josso··on BinDiff now available for free
Version 2 of Hopper had a Windows version available, but with later versions it has been discontinued: https://twitter.com/bSr43/status/672185178236825601
josso··on Knuth 3:16 (2002)
Probably Donald Knuth's book "3:16 Bible Texts Illuminated" where Knuth goes through chapter 3, verse 16, of most books in the Bible.

http://www-cs-faculty.stanford.edu/~uno/316.html

http://www.amazon.com/3-16-Bible-Texts-Illuminated/dp/089579...

While we’re at it, Knuth has also released a book (which is just transcripts of 5-6 lectures) wherein he discusses the 3:16 project: "Things a Computer Scientist Rarely Talks About"

josso··on Amazon's customer service backdoor
I assume it's because AWS uses Gandi as their registrar.[1]

josso··on iOS 9.3 Preview
Not quite true. Apps aren’t allowed to use private API’s, but some apps still do.
josso··on iOS 9.3 Preview
But it might very well be. Just see Pythonista[0] as a great example for scripting on iOS.

josso··on How to listen to (and delete) everything you've ever said to Google
Even then, you don't really delete the recordings, you just delete the link between your account and the recording. As the article points out, the only way to stop Google from having any voice data on you (anonymized or not) is to stop using their voice features.
josso··on iOS Apps Using Private APIs
Because as soon as Apple publish something as an API, they can't change the method because third party apps could now be depending on it. As long as the API is private and undocumented, Apple can change the method from release to release as they see fit.
josso··on Apple’s approach to privacy
Really? It seems to me that most articles conclude that it wasn’t iCloud that was hacked but the celebrities.

Apple also released a press release[1] saying that they “have discovered that certain celebrity accounts were compromised by a very targeted attack on user names, passwords and security questions, a practice that has become all too common on the Internet. None of the cases we have investigated has resulted from any breach in any of Apple’s systems including iCloud® or Find my iPhone.”

josso··on Apple Delays Release of WatchOS 2 Due to Bug
Mavericks was released later than Yosemite. I wouldn’t say either of those were delayed. Both were released in the ‘fall’ as Apple announced at both WWDC ‘13 and ‘14.
josso··on GDB Dashboard
Does anything like this exist for LLDB?
josso··on Google’s look, evolved
I visited Google Dublin last year and found that they still used the old beveled Google-logo for e.g. letters and papers. Not the slightly beveled logo from 2010-2013, but the old one from 1999-2010.

josso··on Ellen Pao Is Stepping Down as Reddit’s Chief
Not aggressive enough:

> So why am I leaving? Ultimately, the board asked me to demonstrate higher user growth in the next six months than I believe I can deliver while maintaining reddit’s core principles.

josso··on Ask HN: What are your favorite videos relevant to entrepreneurs or startups?
For those still in college, I think Zach Holman's talk ”If Only I Knew This Shit in College” is pretty good. He describes why he thinks startups are great, what they allowed him to do, what made him join GitHub, and how to keep improving.
