Lorry :unverified:I figured it was time to write a weblog post breaking down the political and illogical farce of Trudeau's executive actions on firearms these last few years. You probably won't see many posts like this from the far left, but as the saying goes: "When you go far enough left, you get your guns back."Oh yeah, I should put a link instead of spending all of my time writing an alt-text on that free Tornado spud-gun advert that doesn't even link anywhere.<a href="https://superhighwayman.com/2025/canadas-gun-bans/" rel="nofollow noopener noreferrer"

HaraldWhen you move, for example your software from Github to Codeberg, you should install a Nachsendeantrag (forwarding request).😜 Not the least because the old version persists in search engine results.I now did so on Github leading to my NFA/DFA software for Java: <a href="https://codeberg.org/harald/monqjfa" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://codeberg.org/harald/monqjfa</a>Which was previously hosted on <a href="https://nrw.social/tags/github" class="mention hashtag" rel="tag">#github</a>: <a href="https://github.com/HaraldKi/monqjfa" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://github.com/HaraldKi/monqjfa</a><a href="https://nrw.social/tags/codeberg" class="mention hashtag" rel="tag">#codeberg</a> <a href="https://nrw.social/tags/monqjfa" class="mention hashtag" rel="tag">#monqjfa</a> <a href="https://nrw.social/tags/nfa" class="mention hashtag" rel="tag">#nfa</a> <a href="https://nrw.social/tags/dfa" class="mention hashtag" rel="tag">#dfa</a>

Harald<a href="https://nrw.social/tags/monqjfa" class="mention hashtag" rel="tag">#monqjfa</a>, my <a href="https://nrw.social/tags/nfa" class="mention hashtag" rel="tag">#nfa</a>/#dfa, <a href="https://nrw.social/tags/regex" class="mention hashtag" rel="tag">#regex</a> library for <a href="https://nrw.social/tags/Java" class="mention hashtag" rel="tag">#Java</a> got some cleanup in the way finite automata are built. They do not only have the accepting states, but a state may also store a value. The values can be used for special tricks during state traversal. Historically the only "trick" was that this was an accepting state.The latest refactoring made it clearer that more can be done and how states with values and accepting states are related.<a href="https://harald.codeberg.page/monqjfa/" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://harald.codeberg.page/monqjfa/</a>Feedback welcome.

Harald<a href="https://nrw.social/tags/monqjfa" class="mention hashtag" rel="tag">#monqjfa</a>, my finite automaton library for <a href="https://nrw.social/tags/Java" class="mention hashtag" rel="tag">#Java</a> got Capturing ParenthesisWait, WHAT? This is impossible with a deterministic finite automaton!Yes it is, in full generality. But in a limited fashion it is possible, and I am not at the end of the road of this experiment.<a href="https://codeberg.org/harald/monqjfa#dfa-versus-capturing-parentheses" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://codeberg.org/harald/monqjfa#dfa-versus-capturing-parentheses</a><a href="https://nrw.social/tags/jvm" class="mention hashtag" rel="tag">#jvm</a> <a href="https://nrw.social/tags/nfa" class="mention hashtag" rel="tag">#nfa</a> <a href="https://nrw.social/tags/dfa" class="mention hashtag" rel="tag">#dfa</a> <a href="https://nrw.social/tags/regex" class="mention hashtag" rel="tag">#regex</a>

HaraldYou sure have wondered what practical use the intersection of two regular languages has.😀 It is not live changing, but hey, at least interesting.😎 (To a certain tribe.)Here it is: <a href="https://miamao.de/blog/2024-08/18.A_Practical_Use_for_Regular_Language_Intersection.html" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://miamao.de/blog/2024-08/18.A_Practical_Use_for_Regular_Language_Intersection.html</a> <a href="https://nrw.social/tags/cs" class="mention hashtag" rel="tag">#cs</a> <a href="https://nrw.social/tags/computerscience" class="mention hashtag" rel="tag">#computerscience</a> <a href="https://nrw.social/tags/informatik" class="mention hashtag" rel="tag">#informatik</a> <a href="https://nrw.social/tags/endlicheautomaten" class="mention hashtag" rel="tag">#endlicheautomaten</a> <a href="https://nrw.social/tags/finiteautomata" class="mention hashtag" rel="tag">#finiteautomata</a> <a href="https://nrw.social/tags/nfa" class="mention hashtag" rel="tag">#nfa</a> <a href="https://nrw.social/tags/dfa" class="mention hashtag" rel="tag">#dfa</a> <a href="https://nrw.social/tags/monqjfa" class="mention hashtag" rel="tag">#monqjfa</a>

Harald<a href="https://nrw.social/tags/monqjfa" class="mention hashtag" rel="tag">#monqjfa</a>, my <a href="https://nrw.social/tags/nfa" class="mention hashtag" rel="tag">#nfa</a>/#dfa, <a href="https://nrw.social/tags/regex" class="mention hashtag" rel="tag">#regex</a> library for <a href="https://nrw.social/tags/Java" class="mention hashtag" rel="tag">#Java</a> got its first new feature during current modernization. The last operation of finite automata/regular languages which was missing: intersection You can now write a regular expression "some.*stuff&(END)^" which meansMatch strings which match - some.*stuff - AND (the &) at the same time - any string NOT CONTAINING (the ^) ENDAllows to use .* but avoids a match across a hard end, e.g. the string "END".<a href="https://codeberg.org/harald/monqjfa" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://codeberg.org/harald/monqjfa</a><a href="https://nrw.social/tags/computerscience" class="mention hashtag" rel="tag">#computerscience</a>

Though it has some coolness in the defaults used 😀 .<a href="https://codeberg.org/harald/monqjfa#example-application" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://codeberg.org/harald/monqjfa#example-application</a><a href="https://nrw.social/tags/informatikEdu" class="mention hashtag" rel="tag">#informatikEdu</a> <a href="https://nrw.social/tags/informatik" class="mention hashtag" rel="tag">#informatik</a> <a href="https://nrw.social/tags/endlicheautomaten" class="mention hashtag" rel="tag">#endlicheautomaten</a> <a href="https://nrw.social/tags/finiteautomata" class="mention hashtag" rel="tag">#finiteautomata</a>

HaraldI finished another round of modernizing my (Non)deterministic Finite Automata (<a href="https://nrw.social/tags/nfa" class="mention hashtag" rel="tag">#nfa</a>, <a href="https://nrw.social/tags/dfa" class="mention hashtag" rel="tag">#dfa</a>) <a href="https://nrw.social/tags/Java" class="mention hashtag" rel="tag">#Java</a> library.Now with <a href="https://nrw.social/tags/Javadoc" class="mention hashtag" rel="tag">#Javadoc</a> on the <a href="https://nrw.social/tags/Codeberg" class="mention hashtag" rel="tag">#Codeberg</a> pages for the project. The link is at the top of the README.<a href="https://codeberg.org/harald/monqjfa" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://codeberg.org/harald/monqjfa</a>

HaraldAfter years I looked again at a <a href="https://nrw.social/tags/Java" class="mention hashtag" rel="tag">#Java</a> library I once wrote to create (Non)deterministic Finite Automata (<a href="https://nrw.social/tags/nfa" class="mention hashtag" rel="tag">#nfa</a>, <a href="https://nrw.social/tags/dfa" class="mention hashtag" rel="tag">#dfa</a>). I removed a lot of stuff to trim it to the real core. Now I will slowly add features again.In contrast to builtin regular expression in Java, this one does DFAs and also allows to visualize them (see FaToDot). Javadoc and tutorial are not up, but source code is on <a href="https://nrw.social/tags/codeberg" class="mention hashtag" rel="tag">#codeberg</a> .The name prefix, monq, was not invented by a native french speaker. 😀 <a href="https://codeberg.org/harald/monqjfa" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://codeberg.org/harald/monqjfa</a>
