The other related thought was that the 'reproducible' diagram might have<br>
inspired the current r-b logo draft (even if it was not yet drawn, r-b<br>
people have it in their heads), except that there are only 2 nodes and 2<br>
arrows.<br>
And people might eventually ask us (or themselves) what the 4<br>
nodes+arrows in the logo actually represent.<br>
<br>
My best guesmeeting and draftss so far was about diverse double<br>
compilation [1]<br>
where you can<br>
1. use two (or more) different compilers with the same compiler source code<br>
<br>
2. to get two different but equivalent intermediate compiler binaries<br>
<br>
3. and use those to generate identical final compiler binaries.<br>
And sure, that only works if it builds reproducibly.<br></blockquote><div><br></div><div>No, nothing quite so complicated ;).</div><div><br></div><div>I introduced the 4 nodes in <a href="https://wiki.debian.org/ReproducibleBuilds/Logo#A.2317">https://wiki.debian.org/ReproducibleBuilds/Logo#A.2317</a> , representing</div><div><br></div><div>- the source on the left</div><div>- 2 compilation runs in the middle (for example, one on some CI system and one on some 'trusted' machine)</div><div>- convergence to the same resulting binary on the right.<br></div><div> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
Somehow I feel that I would want a logo that is simpler to explain,<br>
like the 2 nodes + 2 edges<br>
= you build it twice and always get the same (bit-identical) results<br>
<br>
How much do we care about explainability?<br>
Is it to late to further simplify the design?<br></blockquote><div><br></div><div>I don't think it's necessarily too late, but I feel the explanation above is simple enough. I agree that 2 nodes and 2 edges can also be sufficient to express the concept, but it doesn't look as nice IMHO ;). The 4 arrows make sense to me since building software is essentially "download the source, perform the compilation, upload the result".<br></div><div><br></div><div><br></div><div>Arnout<br></div></div><br></div></div>
