    Yep, the antibiotic regimen they put you on is no joke, either. It wipes out all your intestinal flora, leaving you super vulnerable to recolonization (and those spores are real fucking hard to eliminate).

    My grandmother had a fecal transplant and she cleared up in days, after literal months of illness.

    Oh definitely, there are lots of clever approaches you can take, and I'm certainly not smart enough to think of them all. Writing high-performance HSA code takes a lot of performance testing and tuning, and writing your code in the most "obvious" way (coming from a single-threaded CPU background) will generally result in relatively abysmal performance.

    The most important thing when writing high-performance code is to know your architecture, especially all the limitations. Console games are great for that, because they target one specific chip, so you can really optimize the hell out of it. :)

    Real trans people exist that don't fit into the truscum narrative. And hey, I personally know binary-identified trans people that identified as genderqueer for a time. All that shitting on non-binary folk does is discourage people from exploring and finding their gender.

    "people who claim to be transracial transpandas that identify as on every tuesday divisible by a prime number in base 7 and use social justice as an excuse to cover for their own bigotry" are not even close to real.

    I can't even tell if you understand this point.

    Yep, this is totally right. The main thing keeping an algorithm from running well on GCN cores is being branch-heavy. While I haven't kept up-to-date on the terminology, only one instruction at a time can be executing across a set of inputs.

    The following code is pretty understandable and quick on a CPU. But on a GPU, performance suffers.
          if (unitOnFire){
              flailAround();
          } else {
              doFightRoutine();
          }
    So, if you have 128 baddies, and 2 are on fire, first the GCN will evaluate the if (with no branch prediction, afaik), then execute flailAround() for the 2 that's on fire. Only then will it execute the 126 fightRoutines (simultaneously).

    Interestingly, ternary expressions, if possible to use, can frequently be optimized so that they do not incur this large performance penalty*. Something like the following:
            health_change = (unitOnFire) ? -100 : 0;
            unitHealth += health_change;
    So yeah, coding for SIMD stuff is tricky to optimize.

    * Some compilers will also optimize simple/equivalent if statements so that they run quickly, but I have no idea if that's the case for the PS4 APU.

    Yes, in the United States, most employees are "at-will" - meaning that either the employer or employee may terminate the employment contract at any time, for any reason (save for discrimination against protected attributes, such as race, religion, etc).

    I don't like it either, but that's how the laws of the land are, and the possibly unethical actions of the employer do not mean that Comcast was behaving unethically.

    Yeah, if that person actually existed. But they don't, and the fact that you've got to resort to such incredible hyperbole is kind of telling.

    You do know that, like, almost every famous "transethnic/transracial" person is quite obviously an anti-SJ troll, as soon as you look into it? Y'all sit around making fake accounts & posts, fall for your own trolls, then post it up proudly "See this is why tumblr is terrible." The demons you're battling *aren't real.*

    And yeah, some people actually do identify as "tumblr genders" - demigirl, or agender, or whatever. So what? That's between them and their friends & family - it affects the people in their lives, but not ours! Literally, the only thing that anti-truscum are asking, is "Mind your own business."

    Trust me, I'm no fan of Comcast, nor corporations in general - I'm voting socialist this election. But this dude was clearly out of line, and I'd expect a mom&pop store receiving such abuse to do the same.

    In the end, it's the employer's "fault" for deciding that his actions were fire-worthy - Comcast just said "hey, look at what your employee is doing."

    The submitter says "be careful when you exercise your first amendment rights," which attempts to frame the issue as one of "free speech."

    Really, it sounds like the guy called up Comcast, was a total asshole, bad enough that a guy at Comcast told his employer what kind of person they kept employed. Bad enough that his employer would fire him for it, so we can only guess at the content, but I'm willing to bet it was pretty abusive. Those customer service people put up with a whole hell of a lot on a daily basis, so this was probably something above and beyond the normal abuse people hurl at Comcast (justly or unjustly).

    You could argue that the employer should have shown the guy the email summary, but that's on the employer's conscience.

    Like, I know that Comcast is a terrible company, and it sounds like he was right to be pretty upset with them for the terrible customer service he received. But given that he makes no attempt to explain or defend what he said on those calls, I'm guessing he crossed *way* over the line. If you're a terrible person, maybe you should be fired.

    Because I love something, doesn't mean I trust it blindly. You can love your wife, but if you see signs that things might be going amiss, you would dig a little deeper to determine if there is really something nefarious going on or if there is just change happening. Or at least, I would. If your wife's phone is going off all hours of the night and she's been working "late" every night for the last 3 months with no history of having done that in the past, would you just blindly trust that everything is fine, because you love her?

    Shrugs. That's how they identify themselves, guess I was misinformed on that point, if truscum.tumblr.com can be believed.

    I have gender dysmorphia, binary-identified, have medically transitioned, and I'm not a "die cis scum"mer. Strangely enough, I don't get hate or anyone accusing me of being "truscum." Do you know why? It's because I'm not shitting on other people's identities, and I recognize that there are human beings who are trans who have different experiences than I do.

    "Truscum" is only used to denote trans people who are policing *other* trans people's identities. Anyone saying that they're being attacked simply for *being* traditionally binary trans is... misrepresenting, at best. We don't take issue with people having dysmorphia or being binary trans folk - we only take issue with people saying that there's only one correct way to be trans, and everyone else is just pretending.
