<description><p><a href="www.han.nl">HAN University of Applied Sciences</a> kindly did an
accessibility test of the mCaptcha widget and the showcase site, which
features a real world integration of mCaptcha in a third-party service.
The report motived us to make screen reader testing an integral part of
the release process.</p>
<p>Here are the results:</p>

<description><p>mCaptcha uses a Proof-of-Work (PoW) based algorithm to offer
Denial-of-Service protection, because of <a href="https://www.w3.org/TR/turingtest/#proof-of-work">its excellent accessibility
characteristics</a>. PoW
within mCaptcha is configuration &mdash; webmasters can configure
<a href="/docs/terminology/difficulty-factor">difficulty factors</a> for their
installations, which determines waiting time for visitors. But PoW can
become inaccessible if webmasters choose a very high difficulty factor.
So they have to maintain a balance which imposes sufficient load on DDoS
attackers while also being accessible to common folk.</p></description>

<description><p>Hello and welcome to the July, 2022 monthly report!</p>
<h2 id="tldr">TL;DR</h2>
<p><em>Codeberg is trying out mCaptcha, Gitea is getting mCaptcha support,
mCaptcha supports MariaDB, I&rsquo;ve applied for NLnet and Open Tech Fund,
documentation is updated: tutorials and glossary is added and glue libraries
have new releases.</em></p>
<h2 id="codeberg-is-deploying-mcaptcha">Codeberg is deploying mCaptcha</h2>
<p>Codeberg is committed to trying out mCaptcha to make their platform more
accessible: they currently use a text-based CAPTCHA, which will be
replaced by mCaptcha. The decision was finalized after I presented
mCaptcha to them at a meeting their organized. Please see
<a href="https://batsense.net/talks/codeberg-introducing-mcaptcha/">here</a> for
slides.</p></description>

<h2 id="mcaptcha-is-incorporated">mCaptcha is incorporated!</h2>
<p>I spent June doing non-technical tasks but I made significant
progress: I had been trying to do it since summer 2021, but I faced
various setbacks along the way. A family friend, who is also an auditor
helped me finally get mCaptcha incorporated!</p>
<p>And we&rsquo;ve already filed successfully filed the first tax return too!</p></description>

<description><p>Hello and welcome to the May 2022 edition of the monthly report!</p>
<p>mCaptcha, for a while was showing all the signs of a dead project:
no commits on the repositories and no monthly updates. But the project
is far from dead!</p>
<h2 id="python-bindings-to-mcaptcha-powhttpsgithubcommcaptchapow_sha256">Python bindings to <a href="https://github.com/mCaptcha/pow_sha256/">mCaptcha PoW</a></h2>
<p><a href="https://github.com/mCaptcha/pow_py">pow_py</a> contains bindings to
<a href="https://github.com/mCaptcha/pow_sha256">pow_sha256</a>, the
<a href="https://en.wikipedia.org/wiki/Proof_of_work">proof-of-work</a> library
that mCaptcha uses. For the uninitiated, the bindings allow for python
programs to automatically solve mCaptcha.</p></description>

<description><p>Hello and welcome to the first edition of the monthly report!</p>
<p>I believe free software like mCaptcha is critical to a healthy internet
but being a one-person show, there&rsquo;s hardly any accountability in the
way software is built. I hope, through monthly reports, I can explain
the logic and intentions behind decisions taken in the development
process.</p>
<p>This month, the following things were accomplished:</p>
<h2 id="1-full-librejs-compliance">1. Full LibreJS Compliance</h2>
<p>The CAPTCHA widget and the admin dashboard are 100% LibreJS compliant!</p></description>

<description><p><strong>Survey link:</strong> <a href="https://survey.mcaptcha.org/survey/campaigns/b717e51e-24d4-4ab6-912f-de2dfe3ce1fe/about">https://survey.mcaptcha.org/survey/campaigns/b717e51e-24d4-4ab6-912f-de2dfe3ce1fe/about</a></p>
<p><strong>NOTE:</strong> The survey(at least, the lucky draw is temporarily suspended
due to some logistical reasons. Apologies for any inconvenience caused.</p>
<p>mCaptcha relies on a
<a href="https://en.wikipedia.org/wiki/Proof_of_work">proof-of-work(PoW)</a>
mechanism to guard against bots. In order for this to be effective, the
difficulty factor should be configured properly. If the difficulty
factor is too high all the time, it will inconvenience the users and if
it&rsquo;s too low during attack, the defence will be weak.</p></description>

<description><p>mCaptcha uses a
<a href="https://en.wikipedia.org/wiki/Proof_of_work">proof-of-work(PoW)</a> mechanism
to rate limit users or potential bots. In order for this to be
effective, the PoW should be configured properly. The difficulty
requirement can&rsquo;t be too high, as it could cause accessibility issues on
the client-side while at the same time, it shouldn&rsquo;t be too low, as it
wouldn&rsquo;t offer proper protection against bots.</p>
<p>Malicious bots(the ones that wreak havoc), run native code which is
capable of running in a multi-threaded context. This creates an unfair
advantage for crackers using these bots over legitimate users, who
usually use browsers to access a website.</p></description>

<description><p>At mCaptcha, we believe in digital freedom and privacy and so we built a
<a href="https://en.wikipedia.org/wiki/Proof_of_work">proof-of-work</a> based
CAPTCHA system that doesn&rsquo;t track. Seriously, no tracking. But that
isn&rsquo;t the killer feature, our system doesn&rsquo;t require the user to
pick cars or ID sidewalks &mdash; our system does it&rsquo;s thing(usually
at the click of a button) and gets out of the way.</p>
<h2 id="how-does-it-work">How does it work?</h2>
<p>mCaptcha uses SHA256 based proof-of-work(PoW) to rate limit users.</p></description>
