    In the medical case, the real WTF was the user making fun of it. There are men who have a vagina and women who have a penis.

    "Buoy Health" could be right. Back in year 2000, Bernie worked for a provider of a Hospital Information System. Before the next release, all staff was testing, and Bernie was very fond of finding new stupid bugs. E.g. he came up with the diagnosis "prostate cancer" for a female patient. No problem, the system accepted that without any error messages. So Bernie filed a bug report. Then a colleague told Bernie: "Can you be sure that this diagnosis is wrong? Imagine, she is now legally a woman, but used to be male before, and not all of the operations have been completed yet? Well, anyway, you're right that we should issue a warning message."

    The wonders of rounding error coming to bear once again.

  • Kashim (unregistered)

    The hex file size comment makes total sense if you understand about block size and things that can happen when you copy a file from place to place. We used to get all kinds of failed comparisons because people would remote desktop from a Win 7 to a Win XP machine, and copy a file from 7 to XP, and XP would always expand the file with 0s at the end to match the block size on disk (never learned why). In the end, the two files were identical, except that one had a bunch of 0s appended to the end, which don't cause any difference in the data, but do cause a difference in size. The rounding error at the end is just a rounding error. TRWTF is the lack of WTFs in todays TDWTF.

  • Zenith (unregistered) in reply to Kashim

    Thank you! Somebody on a computing blog understands a concept like block size!

  • James (unregistered)

    But then wouldn't the difference be the 0's?

  • Alchemist (unregistered) in reply to James

    The zeros aren't actually in the file, they're just tacked on to the end to fill the block. It's mainly a file system difference. Since the example shows both files to be in the same folder, one possibility is some weird filesystem quirk caused one file to be X+1/y blocks. The second file is probably written sequentially so the first part of it fills the rest of that partial block. Then, more guessing here, the filesystem reports file sizes based on blocks somehow so that last block gets counted towards both files, but there's nothing after the second file's partial block so it actually gets sized as X+1 blocks.

    The more likely explanation, however, is filesystem corruption. The files are identical, stored in the same number of blocks, but the file metadata has been corrupted to report the wrong size. The internal data and the start and end inode records are correct, but the filesystem reports incorrect size.

    Even though it's possible that vaginal issues are causing upper back pain - I'd imagine it's a tiny minority of the cases where the user identified as "Male" and the software should pick some more common ones or ask more questions before providing those

    Also, all theoretical physics does not break down into 4D multi-color squares. How thin is the ink? How fast does it fade?

    The Einstein conjecture that 3D particles can be modeled in 1D throughput of course leaves open the door for uncertainty. Faking out humans is meaningless, no matter if you use planetary orbits, or TV screens or CPU signals.

    Take the Laplace curves of overshoot, critically damped, and the purely harmonic. Mirror it at the origin over the frequency axis, then do a revolve sweep over the amplitude axis. The frequency of that sweep will give you a relative time. The holes in that sweep will give you observable uncertainty. The length of that sweep will give you deduction in accordance to Dr. Nemiroff's constant.

    That explains everything. Quantum systems, stellar systems, observation of astrophysics, the Spontaneous Generation of the Expanding Universe, evolution in terms of deductible self-limiting anthropology, market forces. Everything.

    The only thing stopping it is a masquerade of bitter old people who embrace their individual identities in the form of the deaths of others. They are pushed forward by past crimes, not pulled forward by the sight of future glory.

    They see themselves as immortal already, and just make things up, like we're going to summon aliens, or boil us alive, or break the Earth apart, or unleash incurable diseases if we ever try to do real healing.

    I have seen plenty of error'd posts pointing out values being too specific. If the value is too specific, then it seems silly. Here we have an error'd post about not being specific enough.

    So if rounding is an error, and not rounding is also an error, then what is a developer supposed to do? How do we algorithmically determine where the value precision should be? What rounding limit is not going to be seen as silly in some cases or to some people?

  • Velox (unregistered) in reply to BernieTheBernie

    I am MtF post-op, and they actually do not remove the prostate. So even having finished all operations, and being legally and physically female, I will still need a prostate exam when I get to that age (though the risk of prostate cancer IS greatly reduced)

  • airdrik (unregistered) in reply to ooOOooGa

    re: rounding error; if the difference can't be determine due to rounding (or is within a couple of the second-most-significant digit) then it should post the needed difference as an appropriately-sized amount, e.g. "you need to free up 3 KB of space". (in other words, it is a WTF because the message didn't give the user enough info to fix the problem)

    I'll second Mister Monk's comment; the software should take into account information already given and rank suggestions based on how common they are with the information given.

    Lastly on the identical files, of course it is a WTF because it assumes that the user knows enough about file systems etc. to understand what it's talking about. Even if the userbase of the app is expected to just know, a link to an explanation would still be useful.

  • Brian (unregistered) in reply to BernieTheBernie

    Which is why it's important to use specific, precisely-defined terms when it comes to scientific matters and not play politically-correct word games that don't generally apply to the population at large. If you've got a Y chromosome, you are biologically a male with all the specific health risks that come with it (barring certain exceptionally rare cases that come with their own set of issues), and likewise for biological females. Biology doesn't care about artificial legal constructs... insisting otherwise could be hazardous to your health.

  • Alon Altman (google) in reply to Brian

    You are wrong. So very wrong. Y chromosomes are not linked with biological sex except for a handful of genetic conditions. Even then, the exact chromosomal composition matters.

    Many health-related issues depend on specific organs (genitals, gonads, prostate, breasts, uterus, etc) and on hormonal levels. As a non-binary trans person I need both regular breast exams, and a prostate exam, but I am less prone to UTIs compared to most cis women.

    The WTF with the health site is they ask for gender in the first place, rather than more detailed medical questions, and they do not allow non-binary genders to be selected.

  • Jakub Narębski (unregistered) in reply to Alon Altman

    A lot of the cases of "too specific" are just as much about mis-use of floating point math. The very specific result come from floating point errors, while in many case it would be better to use integer math (e.g. counting cents), "decimal" types, or explicitly rounding.

  • markm (unregistered) in reply to Mister Monk

    But the website isn't even suggesting vaginal problems that could cause lower back pain, it is presenting several synonyms for vaginal itch. This would have been wrong even for someone with a vagina. The TWTF is that it indexed to a whole different part of the diagnostic tree.

  • markm (unregistered) in reply to Alon Altman

    "The WTF with the health site is they ask for gender in the first place, rather than more detailed medical questions, and they do not allow non-binary genders to be selected."

    No. For over 99% of people, a Y chromosome corresponds to male organs and hormones rather than female, which affects many medical conditions. If there is a problem with the question asking for gender, it's perhaps that it doesn't clearly say that it's asking about biological gender, not about how you feel. If you have a penis rather than a vagina, you aren't going to have vaginal problems even if you think you're a woman. And if you're one of the tiny minority that is physically intersex, either naturally or from hormone therapy and surgery, you'd better get your medical advice from a doctor that understands just how you are intersex, not from a website which was designed for the vast majority and cannot take your uniqueness into account.

  • (nodebb)

    Rather than showing the space required and space available separately, which are subject to rounding, why not take the difference first?

  • You dont want to know and I do no want to tell (unregistered) in reply to markm

    It is estimated that 1% to 2% of the Western population has some kind of intersex condition - about as much as people with red hair - which is totally distinct from transpeople - up to 0.5% - of which the transwomen post op do have a (neo) vagina. Multiply with the population of, say, the United States, and that is a lot of people. Furthermore, you do not become intersex due to hormone therapy, you may get that as treatment if you have on of the few of the several dozen varieties of intersex or are trans or suffer from hormonal deficiencies due to, say, cancer. Please refrain from spreading disinformation.

    I will grant you that both intersex people and transpeople know better than to take advice from a medical website about their hormone levels or genitalia especially one which shows a poor implementation as this.

    Am I the only one who noticed that the "landlord peace of mind cover" looks like male genitalia?

  • Brian W. (unregistered) in reply to BernieTheBernie

    As the guy who submitted the Buoy Health WTF, I am grateful to the dailywtf community for immediately pointing out issues of complexity and nuance in the topic of sexual identity, and the ambiguities that correspond to those issues when trying to design a symptom checker. With that said, I'm just a regular guy, and my inexperience with having dealt with the above issues is why I jumped to conclusions and thought it was a WTF (e.g., I'm male, so why should I see these results?)

    There were only two options for the question: "Are you male or female?" Presumably, with only those two options, I would select the response based on what anatomy I currently have since there are no other options. Were I in the middle of a reassignment surgery, then I suppose I would've had to use my judgement, but not being a doctor, there would certainly be a gray area there.

    Second, the first value in the search for "itch" doesn't even contain the word "itch".

    Third, the answer was blood cancer (has since been beaten). Buoy was not supposed to guess it right which is why I chose those symptoms. I was expecting something like "skin itch". Anyway, please don't hold that against Buoy. It was misdiagnosed twice by human doctors because the cancer presented itself in a very unusual way.

  • Fair Use (unregistered) in reply to ooOOooGa

    When rounding numbers there are actually four options:

    • No rounding (just cutting digits of the end)
    • Rounding (3.4 => 3, 3.5 => 4)
    • Floor (Always round down; 3.9 => 3) (This is much like no rounding)
    • Ceiling (Always round up: 3.1 => 4)

    A good way to not confuse users is to round to the worst case; i.e. required space, round up; available space, round down.
