<h2><a href="#about_me">About Me</a></h2>
<p>I am Jake Winters, also known by my pseudonym "Inference", a security
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.</p>
<p>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.</p>
<p>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.</p>
<p>I run multiple XMPP channels; a directory of channels can be found on the
<a href="https://inferencium.net/directory.xhtml">directory</a>
webpage.</p>
<p>If you wish to contact me for any reason, you can use my
<a href="https://inferencium.net/contact.xhtml">contact methods</a>.</p>
<h3 id="about_me-gnulinux_or_linux"><a href="#about_me-gnulinux_or_linux">Is it GNU/Linux or Just Linux?</a></h3>
<p>It's just Linux. GNU is unrelated to Linux, which is a kernel
developed by Linus Torvalds. Linux can be used entirely without GNU
software in userspace, and the kernel can be compiled without the use of
GNU tools. Just because GNU tools were used to initally develop and
compile the kernel, and were initially the only available tools for
userspace, does not make this true today, and it never made GNU a part
of Linux itself at any point of time.</p>
<p>Where are all of the other forward-slashes for every other piece of
software on a Linux-based system which makes it just as usable? If a
system is running "GNU/Linux", it should be using more than a single
forward-slash when there is more to the system than only GNU.</p>
</section>
<section id="date_time">
<h2><a href="#date_time">Date and Time</a></h2>
<p>All dates and times across my services are
<a href="https://wikipedia.org/wiki/ISO_8601">ISO 8601</a>-compliant. The
short-form format <code>YYYY-MM-DD</code> is used for dates, and
<code>hh:mm:ss</code> is used for times, with display of seconds being based on
required level of accuracy. The full expression may be used when necessary;
<code>YYYYMMDDThhmmssZ</code> (UTC without offset),
<code>YYYYMMDDThhmmss+hhmm</code> (with positive offset), or
<code>YYYYMMDDThhmmss-hhmm</code> (with negative offset).</p>
</section>
<section id="licensing">
<h2><a href="#licensing">Licensing</a></h2>
<p>I care 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 my
preferred choice, while avoiding copyleft licenses and other licenses which
place restrictions on how my code may be used, and prevent me from including
important proprietary code, such as firmware, which can patch security
vulnerabilities, privacy issues, and stability issues.</p>
<p>All of my code is and will be permissively licensed unless specific
circumstances make it impractical or infeasible to do so. My goal is to share
code which has the least amount of restrictions as possible, to allow wider
propagation of my code and allow more use cases and possibilities, as well as
ensuring proprietary code, whenever required, is permitted to be included and/or
linked to.</p>
<p><a href="https://iso.org/standard/81870.html">ISO 5962:2021</a>
is used for licensing, in the format
<code>SPDX-License-Identifier: &lt;license&gt;</code>; see the
<a href="https://spdx.org/licenses/">SPDX License List</a>
for the full list of available licenses under this standard.</p>
<p>My preferred licenses and rationale for using them are below; any licenses
not listed are chosen on a case-by-case basis.</p>
<h3 id="licensing-code"><a href="#licensing-code">Code</a></h3>
<h4 id="licensing-bsd-3-clause"><a href="#licensing-bsd-3-clause">BSD 3-Clause License</a></h4>
<code>SPDX-License-Identifier: BSD-3-Clause</code>
<p><b>Type: Permissive</b></p>
<p><a href="https://spdx.org/licenses/BSD-3-Clause.html">BSD 3-Clause License</a>
is a highly permissive license which allows content
licensed under it to be used in any way, whether in
source or binary form, and allows sublicensing under a
different license, with the only restrictions being the
original copyright notice must be kept in order to
attribute the original creator of the licensed content,
and the name of the project and/or its contributors may
not be used to endorse or promote products derived from
the original project.</p>
<h4 id="licensing-gpl-2.0"><a href="#licensing-gpl-2.0">GNU General Public License v2.0</a></h4>
<code>SPDX-License-Identifier: GPL-2.0-only</code>
<p><b>Type: Copyleft</b></p>
<p><a href="https://spdx.org/licenses/GPL-2.0-only.html">GNU General Public License v2.0</a>
is a strong copyleft license which restricts use of
content licensed under it by requiring all source code
of the content to be publicly available, making
binary-only form and inclusion of proprietary code
impossible, requiring all derivatives to be licensed
under the same license (allowing sublicensing under only
newer GPL licenses if <code>GPL-2.0-or-later</code> is
specified in the SPDX license identifier), and requiring
the original copyright notice to be kept in order to
attribute the original creator of the licensed
content.</p>
<p>Due to the restrictive and invasive nature of this
license, it is avoided unless such restrictions would be
beneficial to my code; whenever this is the case, the
GNU General Public License v2.0 will be used, rather
than the more restrictive
<a href="https://spdx.org/licenses/GPL-3.0-only.html">GNU General Public License v3.0</a>,
and relicensing derivatives under the GNU General Public
License v3.0 will be disallowed.</p>

is a highly permissive license which allows content

with the only restriction being the original copyright
notice must be kept in order to attribute the original
creator of the licensed content.</p>
<h3 id="licensing-open_source_vs_free_software"><a href="#licensing-open_source_vs_free_software">Do I Distinguish Between Open-source and Free Software?</a></h3>
<p>No. If code is not released under an open-source license and
places restrictions on how the code may be used, it is either
source-available (if viewing the code is permitted) or
proprietary. "Free software" only causes confusion and exists to
push an ideology by a specific group of people. If software
isn't "free", it's not open-source, either.</p>

<h5>Security/Privacy</h5>
<p>Google Pixel devices are the best Android
devices available on the market for
<a href="https://security.googleblog.com/2021/10/pixel-6-setting-new-standard-for-mobile.html">security and privacy</a>.</p>
<p>They allow locking the bootloader with a
<a href="https://android.googlesource.com/platform/external/avb/+/master/README.md#pixel-2-and-later">custom Android Verified Boot (AVB) key</a>
in order to preserve security and privacy
features when installing a custom operating
system, such as
<a href="https://source.android.com/docs/security/features/verifiedboot/">verified boot</a>
which verifies that the OS has not been
corrupted or tampered with, and
<a href="https://source.android.com/docs/security/features/verifiedboot/verified-boot#rollback-protection">rollback protection</a>
which prevents an adversary from rolling
back the OS or firmware version to a
previous version with known security
vulnerabilities.</p>
<p>They also include a
<a href="https://developer.android.com/training/articles/keystore#HardwareSecurityModule">hardware security module</a>
(Titan M2, improving on the previous
generation
<a href="https://security.googleblog.com/2018/10/building-titan-better-security-through.html">Titan M</a>)
which is extremely resistant to both remote
and physical attacks due to being completely
isolated from the rest of the system,
including the operating system. Titan M2
ensures that the device cannot be remotely
compromised by requiring the side buttons of
the device to be physically pressed for some
sensitive operations. Titan M2 also takes
the role of
<a href="https://source.android.com/docs/security/best-practices/hardware#strongbox-keymaster">Android StrongBox Keymaster</a>,
a
<a href="https://source.android.com/docs/security/features/keystore">hardware-backed Keystore</a>
containing sensitive user keys which are
unavailable to the OS or apps running on it
without authorisation from Titan M2 itself.
<a href="https://android-developers.googleblog.com/2018/05/insider-attack-resistance.html">Insider attack resistance</a>
ensures that Titan M2 firmware can be
flashed only if the user PIN/password is
already known, making it impossible to
backdoor the device without already knowing
these secrets.</p>
<p>Google Pixel device kernels are compiled
with
<a href="https://android-developers.googleblog.com/2018/10/control-flow-integrity-in-android-kernel.html">forward-edge control-flow integrity</a>
and
<a href="https://security.googleblog.com/2019/10/protecting-against-code-reuse-in-linux_30.html">backward-edge control-flow integrity</a>
to prevent code reuse attacks against the
kernel. MAC address randomisation is
<a href="https://android-developers.googleblog.com/2017/04/changes-to-device-identifiers-in.html">implemented well, along with minimal probe requests and randomised initial sequence numbers</a>.</p>
<p>Google releases
<a href="https://source.android.com/docs/security/bulletin/pixel/">guaranteed monthly security updates</a>,
ensuring Google Pixel devices are up-to-date
and quickly protected against security
vulnerabilities.</p>
<p>Pixel 6-series and 7-series devices are a
large improvement over the already very
secure and private previous generation Pixel
devices. They replace ARM-based Titan M with
RISC-V-based Titan M2, reducing trust by
removing ARM from the equation. Titan M2 is
more resiliant to attacks than Titan M, and
is
<a href="https://www.tuv-nederland.nl/assets/files/cerfiticaten/2022/09/nscib-cc-22-0228971-cert-final.pdf">AVA_VAN.5 certified</a>,
the highest level of vulnerability
assessment. Google's in-house Tensor
System-on-Chip includes Tensor Security
Core, further improving device security.</p>
<p>Pixel 8-series includes Armv9's
<a href="https://community.arm.com/arm-community-blogs/b/architectures-and-processors-blog/posts/enhanced-security-through-mte">Memory Tagging Extension</a>,
which dramatically increases device security
by eliminating up to 95% of all security
issues caused by memory-unsafety.</p>
<h5>Support</h5>
<p>Pixel 4a (5G), Pixel 5, and Pixel 5a, are
supported for a
<a href="https://support.google.com/nexus/answer/4457705#zippy=%2Cpixel-a-g-pixel-pixel-a-g-pixel-a-pixel-xl-pixel">minimum of 3 years from launch</a>.</p>
<p>Pixel 6-series, Pixel 7-series, Pixel
Fold, and Pixel Tablet, are supported for a
<a href="https://support.google.com/nexus/answer/4457705#zippy=%2Cpixel-a-pixel-pixel-pro-pixel-a-pixel-pixel-pro-pixel-fold">minimum of 5 years from launch</a>.</p>
<p>Pixel 8-series is supported for a
<a href="https://support.google.com/nexus/answer/4457705#zippy=%2Cpixel-pro">minimum of 7 years from launch</a>,
putting it on the same support level as
Apple; Google have even surpassed Apple in
this regard, as Apple does not commit to a
support timeframe for their devices.</p>
