My ISP has already replaced it with a “wifi access charge.” Because the router they provide has WiFi capability.
wittyreference··on Building a $400 at-home DIY spin bike for Peloton and Apple Fitness+
Do you think that working out entirely alone vs. with a trainer is the same thing? Do you think there are some people that would derive a differential benefit by going with one vs. the other?

Do you think that working out entirely alone vs. with a group is the same thing? Do you think there are some people that would derive a differential benefit by going with one vs. the other?

Do you think that emulating being with a group would have value for those that would otherwise value working with a group?

Do you think that anyone who falls into the "works out better with a group and a trainer, or an emulation thereof" must be an idiot? Or do you think that category simply doesn't exist?

From my experience in competitive powerlifting, working out by myself, working out with others, working out with a coach, working out with an app yelling at me, are all very different endeavors, with different outcomes. Maybe I'm just an idiot.

Not if you already have a tablet or smartphone. Which, you know... probably most people in the "looking for an indoor cycling bike" market do.

Never mind that even if they didn't, purchasing an ipad that you occasionally stick on your bike is still a far, far higher utility than a tablet affixed to your bike that only works for biking. Those are not of equal value.

wittyreference··on Building a $400 at-home DIY spin bike for Peloton and Apple Fitness+
I don't know about what the Peloton experience is like, but:

My bike is on a trainer, and I see the following down-sides:

a) My bike on a trainer is really loud. Can't do it early; can't do it when the baby is sleeping, etc.

b) It's a moderate pain in the ass to hook and unhook. Not a huge pain in the ass, but I certainly didn't do it any time of the year it was feasible for me to bike to work.

c) It's dirty. I mean, the bike. I dislike washing the tires so I can bring it indoors even a couple of times a year, never mind if it's coming in and out constantly. And never mind the fact that even washed, my wife sure as hell isn't letting me bring that into a corner of the bedroom.

d) My bike has exposed chains and gearing that, if I'm not mistaken, the Peloton and similar bikes do not. I've got a toddler.

e) Indoor exercise bikes are usually reasonably set up to let you have somewhere to put your phone, or ipad, or kindle, etc. Bikes on a trainer do not. When I'm working out indoors, that makes a big difference for me.

This hasn't been enough to convince me to buy a Peloton, but I can certainly see why someone with more disposable income (or square footage) would.

wittyreference··on Elderly patients 23% more likely to die if surgery is on the surgeon’s birthday
There are emergencies, and there are EMERGENCIES. The former can often wait 24 hours; the latter cannot wait at all. Medicare data does not capture that at all - it only captures the categorical, "surgery type."

e.g., someone has a run of the mill cholecystitis that needs to come out. It can go when there's an opening in the surgical schedule, or tomorrow morning. That's an "emergency" - it came in through the ED, wasn't elective.

Then there's the person w/ chole that looks septic and you're afraid they're going to perf or already have. That person is going to the OR now.

Under Medicare coding, both of those are lap choles, CPT 47562. This doesn't control for that at all, except in the broadest of ways.

Also, a 65yo surgical candidate and a 99yo surgical candidate are wildly different. 99yo isn't going under the knife for anything other than immediate threat of death or unendurable pain. In the lap chole example above, I'm going with a trial of abx in the 99yo unless he's absolutely about to perf; 65yo, sure, let's take the gallbladder out - once he's progressed to sx chole, odds are really good it'll have to come out within the next two years. I think most surgeons would rather do it at 65 than 67.

Looking at the 2x2 of 65, 99, emergency, and EMERGENCY, you capture an incredibly large variety of severity and risk.

wittyreference··on 'New variant' of coronavirus identified
Poking my head in as a physician that is also frustrated with some of the reporting on this topic, it's worth noting that a lot of the reporting seems earnest, but loses context when the person translating 'expert talk' into 'layman talk' isn't qualified to do that translating, and loses some nuance. For instance, referring to your list of "lies":

1. Early on in the pandemic it was highly questionable what the value of masking was. We had mixed experiences to go on: on the one hand, even N95 filtration seemed to not be overwhelmingly effective in stopping viral passage in the laboratory, on the other hand we'd had previous SARS breakouts where universal cloth masking had stopped outbreaks. Neither of these things is "false", they're different facts that needed to be incorporated into a single world-view. What has emerged over time is "masking works, both by reducing the rate of transmission and by reducing viral load - the latter mechanism enough to decreased morbidity, mortality, and symptomaticity rates. It doesn't work by outright stopping viral transmission." "Evolving worldview" isn't the same as "lying."

2. Infection fatality rates were >5%. Important note: there are open and closed case rates. Open Case rates are cases that haven't "ended" yet, either by recovery or death. Closed cases are for those that have. When your population under study is accumulating new cases at an exponential rate, at any given time the majority of "open" cases are early in the disease (and thus haven't died or recovered yet), biasing the IFR downward. At the same time, it means the bulk of cases not destined to end in death are delayed into the future compared to those that end in rapid death - so the closed case IFR is biased upward. For a while we had open case IFR <1% and in a number of places closed case IFR >30%. Early in the course of the outbreak in the US, during the first wave before things skyrocketed and our hospitals went to capacity, our open case rate was ~3% and closed case was around 12%. The more we juggled stats, the more it looked like the 'true' rate was going to be around 4-6%. Again, how these rates evolve over time as we improve detection, management, and treatment doesn't change that this was true at the time.

- Immunity via vaccination and immunity via infection are not the same thing. You can develop an immune response that isn't super effective (e.g., targets a highly non-conserved region of RBD, or was adequate at producing antibodies that provoked macrophage activity but not effective at viral neutralization.) Or you can develop an immune response that isn't long-lasting. The vaccine, on the other hand, is designed to target a highly-conserved region (so it's cross-reactive across many sub-strains, which it is); it's tested for the production of neutralizing antibodies (which it does); and it's given in two doses to ensure a better lasting response by intentionally provoking the development of additional memory cells. These things are different. You falsely equated them, and thus determined one of them must be a lie.

I don't know about, for instance, the ebola thing. Not a paper I read. If I were to be generous, I'd say "reporters fail to convey the nuance and context that helps people make sense of apparently contradictory information." Because that's most of what I'm seeing in your post: attempts at making sense of the world, but without enough information to succeed at doing so, and identifying the gaps in your knowledge as 'lies' rather than ignorance.

wittyreference··on Pornhub just purged all unverified content from the platform
If a business can't run profitably and legally at scale, then that business model is a bad fit for that scale and shouldn't exist at that scale (presuming the laws in question are reasonable, which I think 'banning child porn' qualifies as.)

It's super weird that people seem to constantly start from the premise of, "But their business couldn't possibly [comply with law] profitably at scale! Oh well. I guess until someone comes up with a feasible solution, we'll just have to exempt them from being responsible!"

Imagine if pharma companies went "gosh, but hiring quality inspectors to make sure all of our drugs are untainted just doesn't scale!" I have trouble imagining you saying, "Well, they obviously can't sacrifice scale, so let's just wait and see if a better quality inspection solution comes up."

wittyreference··on Pornhub just purged all unverified content from the platform
I don't think it's unreasonable that the stances that most regularly get highly upvoted to the top of the threads are taken as a gestalt 'HN opinion'.

wittyreference··on How Pfizer delivered a Covid vaccine in record time
That's not what phase 1 is for.

Phase 1 is essentially to test "will this drug cause terrible harm to people who receive it in a reasonably short time frame?" In terms of dosage guidelines, phase 1 studies often don't have variable dosing, or if they do, not an awful lot - because the question around optimal dosing is the target of phase 2.

(Sometimes you can roll 2 and 3 up together, for instance, if the difference in dosing is in duration of therapy rather than an actual difference in drug administered per unit time.)

Phase 1 usually has terribly small samples, because it's only looking for terribly large effects. Seeing homogeneity there, of any stripe, is neither unexpected nor problematic.

(A lot of the vaccine studies rolled up phase 1/2 together because we already have a pretty good understanding of what these delivery mechanisms do to people, and so while you'd be cautious in administering to the initial study participants, it really didn't merit a "test it on five people and hold your breath" approach.)

wittyreference··on George Orwell’s 1984 through a neuroscience lens
I'm a physician in a hospital that has literally entire floor units - plural - occupied by nothing but dyspnea, a respiratory step-down unit that has become an expansion of the ICU, residents pulled off of every non-internal medicine training program to supplement the internal medicine teams, fellows pulled out of their training programs to supplement the hospitalists, and an ICU so packed that it looks like a bathroom at football stadium.

Eh, I probably would've noticed something's up.

wittyreference··on Understanding mRNA Covid-19 vaccines
Not particularly - I last read about them when I was a bio undergrad, and they weren't brand new then. The key words I'd use in google scholar are 'adenovirus vector mRNA', but be sure to restrict the timeline to pre-2020.
wittyreference··on Understanding mRNA Covid-19 vaccines
The vaccine in this instance is all about delivering a target to the immune system's sentries. If those sentries are defective, or if the hitmen the sentries need to alert are defective, there's nothing this vaccine can do to change that.

"Immune compromise" is generally used as a blanket term, but in many people there are specific immune deficiencies, which may or may not factor into the pathway being targeted here. For instance, natalizumab screws with immune cells' translocation across membranes, and shouldn't play a role in responding to a vaccine (I mean, if it wasn't off the market anyway).

If it's a general immune dysfunction (cancer, diabetes), they will see some benefit, but it will be much reduced - specifically because both responding to the vaccine, and responding to the virus post-vaccination, require the activity of the immune system. What this means precisely will vary with the degree and nature of the immune dysfunction: some folks might see some antibody response, and benefit from repeat dosing. Others might fail to seroconvert altogether, in which case it is what it is.

wittyreference··on Understanding mRNA Covid-19 vaccines
I'll add a point, because otherwise your answer was excellent:

This mechanism was once explored as a means of performing gene therapy in human beings (a couple of decades past). It was abandoned because of its utter failure to produce lasting genetic effects.

That's a big plus here: we have a well-explored platform for having the cells transiently produce a protein we want the immune system exposed to, but which we already know is useless at producing lasting effects. The only lasting effect here will be in the memory of the immune system, not in the cells affected by the shot.

wittyreference··on Twitter limits users interacting with Trump's tweets about 'stolen' election
You make it sound foolish and shallow, but I think it's quite reasonable that the venn diagram has overlap in the middle. These platforms quite intentionally assumed two contradictory roles: that of editor, and that of public square.

When they take steps that are consistent with one of those roles' responsibilities, they undercut the other. To the extent that they quite intentionally did their best to assume both of those roles, it's not entirely ridiculous to give them flak for failing to meet the expectations of those roles.

I'd be more sympathetic if not for the fact that they got into that position entirely intentionally.

wittyreference··on Heavy is the Head that wears the AirPods Max
My Bose QC35 are now seven years old or so, and they still charge up fast and hold it for a good long while. I don't know if they're as good as new, but they're close enough that I can't tell the difference. I don't see why the airpods max should be notably worse.
wittyreference··on Pfizer-Biontech vaccine data stolen in cyber attack
You say that as though having a patent in Country X protects you from IP theft by country Y. When the bad actors and the good-faith actors participate in the same market, and regulations protect good-faith actors only in a submarket, ... uh... of course there's secret data.
wittyreference··on Wall Street Begins Trading Water Futures as a Commodity
In anything with a cyclical component, being right "too early" and being wrong are very nearly the same thing, and certainly close enough as to make no difference.

wittyreference··on Poor evidence that Q-tips are harmful
1) For a PCP that does ear cleanings, you could have done that for peanuts. I used to know an FM guy who would do it regularly for patients (maybe a touch too regularly).

2) Heh, it's actually a standard board exam question about "homeless guy comes in with scratching in one ear." The official answer is that you /don't/ scope first, because if it's a roach, the sudden light can make them scrabble deeper. Which is actually funny, since different bugs respond differently - there have been case reports where people have reported repeated success with taking the patient to a darkened room, opening the ear as much as possible, and having a light pointed near the outside of the ear - luring the bug to crawl out on its own.

Actually, on second thought, I don't know if it's a "standard" board question. Rather, it was something I studied for boards once upon a time. I'm not in EM/FM, so it's not something I've ever had come up again.

wittyreference··on “Overpaid Executive Tax” in SF hits firms that pay CEOs 100X more than workers
I’m confused. What’s to stop these orgs from shuttling all their lower paid employees into a distinct staffing solutions LLC and just use them to “hire” staff for a parent company comprised of executives?

Other fields do this regularly - hospitals often organize their physicians into a distinct staffing org, for instance. It’s entirely legal. So is this anything other than a feel good law that will push some minor corporate restructuring?

Physician income and drug prices are entirely unrelated, except for the oncologists whose salary derives from reselling onco drugs.
