what


Some people can fly mechanical lines.


I also just wrote about leaving GitHub Pages for different reasons <https://pettazz.com/goodbye-gh-pages/>. Sticking with Jekyll for now though because I'm too lazy to rebuild my horribly cobbled together 10 year old theme


This is some real nostalgia. I spent all April Fools' Day probably every year in college trying to figure out how to make this work on my DD-WRT'd wireless router until finally getting it.

It also inspired my own method of dealing with Plex server login sharing https://pettazz.com/how-to-really-piss-people-off-with-plex/ in 2015 which also probably doesn't work at all anymore.


That's not the generator, it's supposed to be the site's favicon


I checked the URL and it pointed at the generator domain.


I don't have any particular use for this right now but the visualization is so good that I actually followed along and get what it's about. Pretty obvious to say but it's super cool and I wish more projects had this kind of quick intro/overview.


I see from elsewhere in the thread that this was a painstaking/manual effort and leverages D3.

Does anyone know if there are projects/libraries to help build this kind of visualization more generically? I realize that no library could every cover every possible use case, but I'd love some kind of framework that makes it easy to build out this kind of thing.

Reveal [1] is great for a web-based slideshow, but I'd love something that helps explain complex systems, even if that requires me to do some heavy lifting.

Same! Raft is something I've heard about for years and always "wanted to get around to" learn, but this visualization just took care of most of that. Hoping there are other good visualizations like this in the future.


This visualization is very good. But the Raft paper itself is also quite understandable (and I say this as someone without any formal CS background who struggles getting through papers). It's main goal, aside from correctness, was understandability after all.

I'd estimate it took me about 2 hours to get through it, but it felt very satisfying because I walked away saying "yup, I see how this works now". Give it a shot!


The reason for case counts staying relatively low in those places has a lot less to do with "herd immunity" and a lot more to do with still being careful. Even though a huge number of people were infected, it was still a very small amount of the population overall, not anywhere near enough to affect the transmission rate with no restrictions.

In MA we're not even close to entirely reopened yet, but as we continue step by step the transmission rate is ticking back up unfortunately: https://rt.live/us/MA


If you look at the numbers throughout the Northeast, you see a remarkable consistency. New cases are at a trickle, despite lots of reopening (more in some places than others) and weeks of mass protests throughout the larger cities.

I am in NYC and mask compliance here is... OK. But people are generally going out a lot, eating out a lot, shopping, etc, with very little concern. Weeks keep passing without even a tiny uptick in the rate of new cases. Clearly, there is something suppressing the transmission rate in this region. The exact same holds true for Europe.


If you haven’t left NYC, it may also be true that our perception of “going out a lot” is about equivalent to much of the nation’s “lockdown” perception.

In other parts of the country, like Florida and Arizona, it doesn’t seem like the transmission rate ever really went below 1: it just hovered around 1.

So now NY, Boston, etc are “opening up” to a roughly equivalent position that those states were in when they were under “total lockdown”: in NYC, we still don’t have indoor dining, for example, whereas Arizona still allows 50% capacity indoor dining despite nearly running out of ICU beds in most hospitals.

When you’re in the center of the epidemic, merely getting to an infection rate of 1 is not good enough. NYC got well below that. I don’t think everywhere else did, and even the places “shutting down again” may not be doing enough.


The rest of New York has been in phase three with indoor dining for a few weeks now.


That doesn't tell you whether people actually are, the way they may be in some other places. Is actual behavior at all the same in, say, NY vs FL?

I'm fatalistic about avoiding the virus in the long run, and I go out whenever I have something to do, but my food has all come from the grocery store or mail order since March. I'm still asking myself "do I need to do this" every time I consider going somewhere.


I can tell you that in Manhattan, what I see are throngs of people with and without masks, enjoying parks and food and drink all day every day, often in crowded patios. Not to mention the hundreds of protests that have occurred.


You've gotta be a bit skeptical of models like this. The source data it's drawn from looks pretty indistinguishable from a flat line; there's no reason to necessarily expect their model is precise or accurate enough to distinguish 1.04 from 0.96.


Rt measures the "acceleration" of the infection. When you're down to a fairly flat ~150 cases per day then by definition Rt is going to be around 1. Also note that the reported daily case totals include backdated tests and when sorted by date, you'll see a steady decline and MA is pretty much flat now (see page 2 & 4 of [0]).

A state that was reporting 10 cases a day consistently would have an Rt of 1.0, if they reported 11, then the Rt would be 1.1. Similarly, VT which has an Rt of 1.07 despite only reporting 5 new cases yesterday as they are bouncing around in the single digits to low teens -- seems like it's basically noise now affecting the Rt there at this point.

It is going to be quite difficult to get it to zero in MA without closing the state borders. Logan Airport had 203,328 passengers through it in May 2020 [1], that's an average of 6777/day, at a 2% positivity rate that could be 135 cases a day right there (not including tens of thousands of people driving into the state, although our neighbors are in similar situations to MA rate-wise).

It's worth noting that MA has recently opened up testing to anyone who wants it so we're likely picking up more asymptomatic cases now. At this point contact-tracing is going to be key although they've had to lay off [2] many of the tracers due to lack of work for them.

The state continues to do well, we've had restaurants open (indoor and outdoor dining) for several weeks now, gyms have been open for a week (except Boston opened gyms yesterday) and 4th July was 10 days ago. The state tested 17K protestors [3] in June and only found a 2.5% positive rate (which was the same as the state-wide rate at the time).

We'll see, but I'm hopeful and will continue to do my part; distancing & masks in public.

But have you actually used a Catalyst app on mac? They're terrible ports as it is right now.


Eh, Catalyst apps are as good or bad as the developer wants them to be. Voice Memos and "Find My" on the Mac are two fantastic Catalyst apps, and certainly better than Electron.

Anyways Catalyst won't even be relevant in the long term, once iPhone apps are written in SwiftUI


Interestingly there's a few mentions of Catalyst improvements in the Xcode 12 release notes:

> When bringing iPad apps to macOS, you can now use the Optimize Interface for Mac target setting to use native macOS controls and Mac resolution

Hopefully this means Catalyst apps will feel a little more like actual Mac apps.


As bad as Electron? I think not.


I often close the Twitter app and Apple's news and stock apps on my Mac mini because the performance is terrible. Hoping they've spent time tuning this more.


Pretty sure all that'll really happen if you stop tipping is that some poor delivery driver gets screwed. Just stop using the apps, order from the restaurant directly, tip your delivery people.


I do realize that this is a pipe dream, but if literally everyone stopped tipping at once, the conditions would have to improve.

Also, I'm from the UK - while tipping in restaurants is semi-common(not expected), tipping delivery drivers is literally unheard of. Doesn't exist, no one does it. And yet.....somehow, delivery drivers still exist as a profession.

My point is - every time you tip, you allow shitty employment practices to continue. It's the same as giving money to beggars on the street - they continue begging because they know it works, it's a self sustaining circle.


You’re right, broadly, but please don’t do this when you’re visiting the US. You’re screwing over a real life, individual person because it pleases you to make a point.


So you're from a country where tipping isn't so engrained or important. Here in the US tipping is the main way service workers make money. Most base wages are simply untenable.

Now, I'm not saying I like that, in fact I hate it. We are in essence subsidizing their employees. It definitely needs to change but please don't encourage people not to tip. There are realistic ways to get rid of tipping. Just stopping tipping isn't one of them. All your doing is hurting the little man/women. Also comparing them to beggars is pretty out of touch.


I live in the UK and know plenty of people who tip delivery drivers. Not to the extent of the US admittedly.

Do you have a source?


A source for what? For people not tipping delivery drivers? I live in the UK and I have never heard about anyone tipping delivery drivers - you are literally the very first person I've read about that tips delivery drivers in the UK. So no, no source, personal experience.


They're talking about "for general disaster preparedness" in this comment. The OP specifically mentions not worrying about water in the case of COVID specifically.


> The only reason busses are the size they are is the labor cost

They're big because they fit 50 people inside a single vehicle instead of 50 different cars.


Common city busses pack from 120-160 people.


That's a crush load number usually it's a lot lower. Unless if you're talking about articulated buses


Just an example number but yeah
