There are things that go wrong when using ActiveSupport, but it's so ingrained in people's workflow that they won't notice.

The one I consider the most annoying: it substantially increases load time. ActiveSupport is huge and just requiring it increases the load time by 1.x seconds. Given what it provides, that's substantial.

The inability to extract a library (or a service) without depending on ActiveSupport is a cost that doesn't exist with the other approaches.

Not to underestimate, your _number_ now responds to `weeks`, and duck typing is the only way you have "interfaces" in Ruby. I can easily picture having a "weeks" or days attribute on some entity and a service object expecting that, now there are subtle bugs when passing accidentally the entity's _value_ instead of the entity itself.

Yeah, they are "minor" things, but the point is dying of thousands cuts.

The last damage is more subtle: devs, even less experienced devs, will feel authorized to monkey patch. In the private codebases I saw (multiple) this is common. It's not a last resort anymore and it ends up becoming a hard problem to debug and resolve.

The ability to monkeypatche pushes devs to NOT design their objects in an extensible fashion. This effectively is the highest damaging consequence, but it's incredibly hard to assess.
What I mean is: binding an enum to an action, which then sends a message containing the enum, deciphering it and executing code based on its value, and not forgetting to define the enum somewhere, when ... you could simply bind the closure to the action.

So instead of:

Button::new(&mut self.increment_button, Text::new("+"))
.on_press(Message::IncrementPressed)

you would write:

Button::new(&mut self.increment_button, Text::new("+"))
.on_press(|| MY_CODE_HERE)

For comparison, in JavaScript you can write:

button.onclick = function(){ ++counter; }

That's quite a direct way of formulating what you want to happen. All in a single line and no Enums involved.

Long haul Covid is generally associated with severe cases. The question then becomes, how much does getting the vaccine reduce a recovered individual's probability of having a severe case? Given that it's pretty rare for reinfections to be serious, and the vaccine does not prevent infection or even serious breakthrough cases, the answer would seem to be "not much."

Physics allows practical applications of mathematics, whether using sine/cosine to explain wave motion or complex calculation of celestial objects, like planetary orbits. Yet it still cannot explain quantum mechanics, i.e. interactions of subatomic particles because there the general laws of physics do not work.
So basically it just comes down to how much of physics knowledge that humanity has obtained up to now really explains the universe - and it seems there are still vasts gaps in science that still needs to be filled.

True, but we aren't comparing a 1 to 0 or 1 to 2. Its 238 to 19. sqrt(238)=+/-15 sqrt(19)=+/-4 (if the numbers are to be believed) . 238/19=12.5 (238-15)/(19+4)=9.7 so it becomes 20% less on the lower end of the fluctuation which is only nominal.

TWA’s mistaken landing at Ohio State: https://www.dispatch.com/article/20120704/news/307049831

The newspaper story makes little sense if read exactly as written since any jet has ample performance to climb away from a balked landing prior to touchdown, so I assume the realization happened after touchdown given the agreement upon review that stopping was the right call.

There’s an image of this on the wall of the “new” (2019, maybe?) terminal building at OSU and I think a few sentences on the lightening they did to fly it out.
The bigger problem is that the risk of hospitalization post-vaccine appears to be lower than the risk of death pre-vaccine. If seven of those eight hospitalized post-vaccine would have died when naively infected, then the difference disappears. Seven out of 32000 is 0.02%, while the risk of death from COVID-19 is 0.4%.

And if you remove hospitalization as an endpoint, you're basically dependent on self-reports. That's not to say I don't believe the conclusions -- they should survive this critique -- but there is reason to expect a little inflation of the ORs.

> people are paid not by the value of their work, but by their scarcity

So the less people there are who own the majority of the wealth on the planet, the more that is justified?

So their value is what, exactly? Scarcity by itself doesn't mean anything. There are diseases that are extremely rare, that doesn't make it more desirable to have them.

The rent seeking, wealth-siphoning people do need the people who build the stuff they live off. That's not true the other way around. You don't have to replace Tim Cook, you just have to get rid of him.

(edit: I don't mean Tim Cook personally, it's not intended as criticism of that particular person; but the amount of wealth such people (not to mention the people where the ratio is WAY more off) bind destroys so much productivity in the people that have to struggle as a result, that they would provide more value to the world and the people in it by not existing, than by anything they did or could possibly do)
I think you might be rather successful in gaining initial market traction by scraping off sites which are closing down. This way, you will also be able to support people who would potentially be loosing a lot of their data otherwise.
This isn’t my experience at all, but I suppose it depends on how you build your applications. I used to be of your opinion, before we moved more and more of our code based from .Net to Python an I was a linq junkie, but these days I think you’re crippling your pipeline if you don’t utilise SQL when and how it’s reasonable to do so.

There are a lot of data retrieval where a stores procedure will will save you incredibly amounts of resources because it gives you the exact dataset you need exactly when you need it.
This implementation uses async/await, data structures from Rust's standard library (alloc crate), plus streams and channels (30 dependencies in total), so it's pretty fancy for a "no_std" project.

Bare-bones Rust executables can start at about 3.5KB, and code size increase on top of that is comparable to C or C++. Rust can be a "portable assembler" if you write code in such style. It can also generate lots of code if you lean into generics (same issue as with C++ templates).

No. They are not inducing mutation in the virus; they are merely culturing the virus so they have controlled samples. Young healthy human subjects are then intentionally exposed to the virus, to, e.g., measure the efficacy of vaccines.

Another way of thinking about it:

* Stars in the Milky Way: 400 Billion

* Galaxes in the universe: 2 Trillion

So (4x10^11)x(2x10^12)=8x10^23 stars in the universe.

* Size of IPv6 address space: 3.4x10^38

Find the ratio between addresses and stars:

* 3.4x10^38 / 8x10^23

IPv6 offers about 430 trillion times more addresses than estimated stars in the universe.

Wearing a mask is a mild annoyance. With vaccine, you might suffer side effects, but even that is short term.

It's basically no-brainer, since getting infected with the virus is more likely to kill you than getting the vaccine.

The only reason people are not getting the vaccine is for various reasons they don't trust that the vaccine is going to help them. Everything else is justification.
I have a $100M SaaS in a different space but the underlying tech is identical. I had this idea ~10 yrs ago when we first started writing our own import logic to move users over from competing services.

I'm in my early 50s, been programming since a teen and got my A+ and Microsoft system admin certs not long after they first came out. About ten years ago I left a partnership and was looking for work to make ends meet until I found the right job. Had an interview with a company for a tech/sysadmin type position. I was interviewed by a 20 something and one of their questions was how I would diagnose and repair a PC power supply problem. I said does the computer come on? No, I'd replace the power supply and get on to other things. She stopped me and started grilling me how I would know if the power supply is bad or not. I told her I could just look at the computer and tell, especially if it isn't powering on. She was getting a little upset and asked wouldn't I use a tester and check the other components, and I told her there's no need to get that involved when it's just a power supply. Needless to say I didn't get the job.

Nope, you don't need to, because of a simple fact that there is a very minuscule amount of IPv6-reliant systems in the wild. Most of them also operate in IPv4 (because IPv4 is more prevalent).

Name me an existing system where:

a) requires IPv6; but

b) not because of its long address.

Good luck finding such a system.
Not really, since IPv6 adoption is low, a service that doesn't also exist on IPv4 practically does not exist, so if you have a good migration path (unlike v6) from v4, you're taking approximately all services with you.

Economist Intelligence Unit: Biennial Safe Cities Index
If you're in software engineering, Jupyter notebooks support a large variety of languages now.

I keep handwritten notes in a notebook of recipes I particularly like. These are useful for making adjustments over many preparations. I guess the bottom line is being willing to enforce an organization on your notes, and then iterate towards a format that makes sense to you. For the recipe notes, time series (like journal entries) works well. Or inline. It depends on the note. Ingredient substitutions can be time series, but wrong measures specified in the recipe would be an inline correction.

Apple is a hardware company that makes phones, pushes for a "green and socio-environmentally fair" agenda and also markets its computers to young people and the education market. Is it really that much of a stretch that this someone at Apple would be interested in working on these areas?

You characterization of Marc Brooker as a "confident beginner" is incorrect.

>But then why do masked populations end up with the same maximum growth rate?

There is no such thing in this study as a "masked population". The authors categorized the states based on the percentage of mask-wearers, according to the IHME data. But the reported infection rates don't distinguish between masked and unmasked.

Your reference [0] looked at whether masks protect the wearer, and explicitly did not study whether masks on the infected protected others: "...no assessment of whether masks could decrease disease transmission from mask wearers to others." (From the Limitations section.) Your other references do not pertain to covid.

The CDC changed their recommendation regarding masks for the vaccinated originally because they were satisfied that the vaccine provided sufficient coverage against serious illness to make unmasked, vaccinated individuals a very low public health risk. That changed when the Delta variant emerged and it became clear that vaccinated and infected individuals could spread the virus as readily as the unvaccinated infected, making them a potential vector and therefore a public health threat. As has been repeatedly reported, masks are primarily to keep the infected from infecting others, and again, there is a mountain of evidence that this is the case.

As an aside, I upvoted your comment because even though I disagree, you presented an argument and provided references to support it.
Jessica has always been brilliant, even to the absent-minded professor type of behavior. When we dated in high school, she'd get so involved in a deep conversation I'd sometimes have to grab her hand at a curb so she wouldn't walk out in traffic. Our conversations were often in English, French, and Spanish as we were the only two students in school taking all three. I imagine those were easier for her than for me. She got a perfect score on her ACT. She at one point wanted to be a nuclear physicist and I have no doubt she'd have had an impact at University of Chicago. She ended up, to the benefit of the software industry, changing her focus.
That would enrage the outrage mob.
Len here. Thanks for the support! We default to using APIs if they're available and only scrape when we need to. In our experience, mid-large sized SaaS companies limit breaking changes at the API level and their UIs are relatively stable.

We know as much about “long Covid, as we know about “long covid vaccine“.

That’s not pro or con anything, it’s just the truth that some are having a hard time admitting.

I’m not sure at what point in the last year “we don’t know” became taboo. Maybe when we wrapped unknowns in policy decisions?

EDIT: yes, we have data for that long Covid symptoms especially in severe cases, and suspected in mild cases, my point was that we do not have enough data to make policy decisions based on this. Currently hard to quantify, as the CDC has anxiety and depression listed as long Covid symptoms.
Consider the realistic uncertainty and probability from previous study of antibody dependent enhancement. It’s not proven that the mRNA therapy won’t worsen covid reaction in the long run.

Its not about vaccine vs natural immunity. Its about immunity vs mandates.

Getting covid intentionally is stupid. If you feel up to it, get the vaccine. Any encounter with covid will be milder.

However, some people have already had it and are frankly being unjustly discriminated in some states and institutions.

I'm not against vaccines but the treatment of previously infected people as second tier has got to stop.
Isn't there some selection bias going on here? Having covid once protects against getting it again - if the first one didn't kill you that is.

Yes, I am. As an example, the French public retirement pension system was built after WWII from a multitude of private pensions that were put in place over decades by various unions/corporations/guilds.

As mentioned in another comment there's no difference between someone choosing say a furry avatar vs someone choosing say a star trek character as their avatar. Same reason: they enjoy that world/universe.
