<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>CraigJPerry</author><text>Is reproducability achiveable?&lt;p&gt;If you preserved an immutable tag of the source code and all its dependencies, a copy of the compiler version used and all build flags, then you’ve still got some big holes in your ability to reproduce a binary:&lt;p&gt;&lt;pre&gt;&lt;code&gt;  1. OS version &amp;amp; patches installed
  2. OS configuration
  3. Hardware used (processors can have weird subtle bugs, microcode can affect execution behaviour, etc etc)
  4. Transient issues - the golden copy to be reproduced for some post event investigation might have contained a bit flip leading to impossible to reproduce verification signatures
&lt;/code&gt;&lt;/pre&gt;
Etc etc&lt;p&gt;Or is reproducability just a spectrum and you try to get further along it with some careful attention to detail, rather than an absolute to be achieved?&lt;p&gt;If the latter are you not cheaper just archiving binaries and tagging them with the source + deps + compiler + arch used to build them? Thats a 5 minute job to setup in your CI process and costs comparatively little to maintain vs wasting expensive human brains chasing down a futile goal.</text><parent_chain><item><author>enriquto</author><text>Rust is alright as a language, but cargo is extremely scary.
