>About Me</a></h2>
|
|
|
|
|
<p>I am Jake Winters, also known by my pseudonym "Inference", a cybersecurity researcher
|
|
|
|
|
based in United Kingdom.<br>
|
|
|
|
|
I am the founder, lead developer, and administrator, of Inferencium.<br>
|
|
|
|
|
All opinions are my own, and are not necessarily shared with projects or people I am
|
|
|
|
|
affiliated with.<br>
|
|
|
|
|
<br>
|
|
|
|
|
I write about my research and experience in cybersecurity and also physical security.
|
|
|
|
|
Most of my postings are security-related, but I occasionally post about other aspects of
|
|
|
|
|
my life.<br>
|
|
|
|
|
<br>
|
|
|
|
|
I am an open source advocate for the preservation and modifiability of source code. I
|
|
|
|
|
believe source code should be considered human knowledge as much as past knowledge and
|
|
|
|
|
teachings were; it is how modern humanity survives and runs.<br>
|
|
|
|
|
Source code being modifiable allows it to be adapted for use by anyone, whether to add
|
|
|
|
|
features, harden it for increased security and/or privacy, or provide accessibility for
|
|
|
|
|
disabled users.<br>
|
|
|
|
|
I am also a modular design advocate for the ability to securely and robustly make
|
|
|
|
|
changes to hardware and software without the entire system being affected.<br>

|

>Licensing</a></h2>
|
|
|
|
|
<p>Inferencium cares about upstreaming and sharing code, strongly preferring licenses which
|
|
|
|
|
have high license compatibility in order to permit sharing code with as many other projects
|
|
|
|
|
as possible; for this reason, permissive licenses are our preferred choice, while avoiding
|
|
|
|
|
copyleft licenses and other licenses which place restrictions on how our code may be used,
|
|
|
|
|
and prevent us from including important proprietary code, such as firmware, which can patch
|
|
|
|
|
security vulnerabilities, privacy issues, and stability issues. All Inferencium code is and
|
|
|
|
|
will be permissively licensed unless specific circumstances make it impractical or
|
|
|
|
|
infeasible to do so. Our goal is to share code which has the least amount of restrictions as
|
|
|
|
|
possible, to allow wider propagation of our code and allow more use cases and possibilities,
|
|
|
|
|
as well as ensuring proprietary code, whenever required, is permitted to be included.<br>
