Some thoughts on this article:
- This guy clearly has a limited understanding of the field. This quote is laughable: "There are only two computationally difficult problems in bioinformatics, sequence alignment and phylogenetic tree construction."
- As a bioinformatician, I feel sorry for this guy. Just like any other field, there are shitty places to work. If I was stuck in a lab where a demanding PI with no computer skills kept throwing the results of poorly designed experiments at me and asking for miracles, I'd be a little bitter too.
- Just like any other field, there are also lots of places that are great places to work and are churning out some pretty goddamn amazing code and science. I'm working in cancer genomics, and we've already done work where the results of our bioinformatic analyses have saved people's lives. Here's one high-profile example that got a lot of good press. (http://www.nytimes.com/2012/07/08/health/in-gene-sequencing-treatment-for-leukemia-glimpses-of-the-future.html?pagewanted=all&_r=0 http://www.nytimes.com/2012/07/08/health/in-gene-sequencing-...)
- I'm in the field of bioinformatics to improve human health and understand deep biological questions. I care about reproducibility and accuracy in my code, but 90% of the time, I could give a rat's ass about performance. I'm trying to find the answer to a question, and if I can get that answer in a reasonable amount of time, then the code is good enough. This is especially true when you consider that 3/4 of the things I do are one-off analyses with code that will never be used again. (largely because 3/4 of experiments fail - science is messy and hard like that). If given a choice between dicking around for two weeks to make my code perfect, or cranking out something that works in 2 hours, I'll pretty much always choose the latter. ("Premature optimization is the root of all evil (or at least most of it) in programming." --Donald Knuth)
- That said, when we do come up with some useful and widely applicable code, we do our best to optimize it, put it into pipelines with robust testing, and open-source it, so that the community can use it. If his lab never did that, they're rapidly falling behind the rest of the field.
- As for his assertion that bad code and obscure file formats are job security through obscurity, I'm going to call bullshit. For many years, the field lacked people with real CS training, so you got a lot of biologists reading a perl book in their spare time and hacking together some ugly, but functional solutions. Sure, in some ways that was less than optimal, but hell, it got us the human genome. The field is beginning to mature, and you're starting to see better code and standard formats as more computationally-savvy people move in. No one will argue that things couldn't be improved, but attributing it to unethical behavior or malice is just ridiculous.
tl;dr: Bitter guy with some kind of bone to pick doesn't really understand or accurately depict the state of the field.
- Inufu 14y agoOut of curiosity, what other computationally difficult problems are there? I'm very interested in bioinformatics, but sadly don't know as much about the field as I'd like.
- zmmmmm 14y agoOne that comes immediately to mind is genome assembly, which is a hugely complex problem, and essential to a variety of fields that rely on re-piecing together the genome without a reference (or with a reference that is highly divergent from the sequence data).
- sampo 14y agoGenome assembly relies heavily on sequence alignment. So: Is genome assembly hard just because sequence alignment is hard? Or would genome assembly present separate algorithmic problems even if there was a super-efficient solution to sequence alignment?
- ufo 14y agoAn extra difficulty with genome assembly is that DNA often has lots and lots of repeated junk sequences that can confuse the algorithms. I don't work with bioinformatics to know how they usually get around this though.
- njbooher 14y agoRepeats aren't necessarily junk (e.g. TAL Effectors http://en.wikipedia.org/wiki/TAL_effector#DNA_recognition http://en.wikipedia.org/wiki/TAL_effector#DNA_recognition). Resolving them requires long reads. PacBio is currently of interest as an alternative to Sanger sequencing for this, although the error rate of PacBio reads is a bit of an issue.
- apathy 14y agopacbio is dead, they just don't know it yet. BGI (or somebody, doesn't matter, BGI is just the obvious candidate) would need to buy 50 SMART sequencers a year just for PacBio to stay in business. That seems unlikely given the lower cost and complexity of Illumina and Life sequencers
