   It's better to just do nothing and allow SIGPIPE to kill your program. That is the reason this signal exists. Python is not a good unix citizen in this case. Compare it to Perl for example where nothing special is required to do the ri

   I think the "calling BS" objection was to your categorical statement: "No computer-to-computer interchange format has comments," and not about whether they are a good idea or not (that is a separate argument). How about

   Why do you believe this? Are you under the impression there is some security problem, or are you opposed to users having more control over how programs run on their computers?

   Well searching/counting/etc k-mers can be done with regexps, but I certainly agree that regexp-based searching is somewhat niche compared to more generally useful similarity searches like BLAST. One comment though: backtracking is

   I'm especially interested in how sequence searching and matching work in libraries like this. Seq has a "match" statement for this task, which implements ACGT characters and _ for a single wildcard base and "..." fo

   This is still in kick-starter phase, but if you don't mind waiting a few months it has a lot of potential IMO: https://www.crowdsupply.com/e-radionica/inkplate-6

    Any reason why you don't give addition and concatenation distinct operators? Perl does this and it's a lot cleaner IMO. Whenever you see a "+" you can consider it an explicit numeric conversion of both arguments: https:

    I just tested and this Makefile works fine with clang, except that -flto should be added to LDFLAGS. In fact I believe it should be there for gcc too, according to https://gcc.gnu.org/wiki/LinkTimeOptimization so perha

    You shouldn't hard-code gcc. make has an implicit CC variable for this: https://www.gnu.org/software/make/manual/html_node/Implicit-... Your makefile will then work on systems without gcc, and it is

    Yes good point. I was careful not to say that perl actually uses rand(3) because I think it may not for portability reasons. Also, I think this may have changed at some point so might be different depending on perl version.
