There's a lot of semi-incorrect information here.

With Optimism, there can be multiple L2 chains, by different "Chain Organizers". When you submit a transaction, you get a receipt from Organizer, a cryptographic promise that it will be included in future rollup.

It means only Organizers can attempt to front-run, by adding a transaction before giving out your receipt. And users can always choose to use different Organizers, those that don't front-run. Since Organizers gain a small amount of fees, it doesn't make sense to be a bad, front-running Organizer.
Exactly - people may very well be mixing up cause and effect.

It could be that a precursor was already spreading prior to the major outbreak but only detected when it hit Wuhan because so many coronavirus experts were concentrated in that area.

> Say I'm doing a drawing/game app and creating a few hundred heap objects a second that need to get garbage collected.

Was literally my job ten years ago to optimize this and I was struggling with a GC'd language with a proprietary implementation (flash+actionscript).

The problem is not with hundreds of heap objects per-frame, the problem is that they would accumulate to the tens of thousands before the first GC trigger happens.

And the GC trigger might happen in the middle of drawing a frame, even worse, at the end of drawing a frame (which means even a 10ms pause means you miss the 16ms frame window at 60fps).

The problem that most people had was that this was unevenly distributed and janky to put it in the lingo. So you'd get 900 frames with no issues and a single frame that freezes.

So most of the problem people have with GC pauses is the unpredictability of it and the massive variations in the 99th percentile latency in the system, making it look slower than it actually is.

Most of the original GC implementations scale poorly as the memory sizes went up and the amount of possible garbage went up, until the GC models started switching over the garbage-first optimizations, thread-local alloc buffers and survivor generation + heap reserves etc (i.e we have lots of memory, our problem is with the object walking overheads - so small objects with lots of references is bad).

The GC model is actually pretty okay, but it is still unpredictable enough that tuning the GC or building an application on top of a GC'd language which has strict latency requirements is hard.

However, as a counterpoint - OpenHFT.

Clearly it is possible, but it takes a lot of alignment across all the system layers, but at that point you might as well write C++ because it is not portable enough to run anywhere.

Sounds like you're only taking 2.1%, with 2.9% going to Stripe. That seems very fair, though it makes me curious if the larger sum appears to be "revenue" on the books. That would be a business model killer for US states with things like franchise taxes that are revenue (rather than profit) based.

If you are talking about installing the Root CA in the iPhone, yeah. That's how I do it in my development devices.

But for a user, iOS Safari (not Safari for MacOS) doesn't show any certificate warning that the user can accept, like other browsers. In fact, it just fails absolutely silently. You'd have to connect it to a Mac and open up the developer tools on the desktop's Safari, to see the errors that are being printed on the JS console.

Otherwise, you'd just be left wondering why it just doesn't work like all the other browsers.

"Virtual Machines (VMs) with Just-In-Time (JIT) compilers are traditionally thought to execute programs in two phases: the initial warmup phase determines which parts of a program would most benefit from dynamic compilation, before JIT compiling those parts into machine code; subsequently the program is said to be at a steady state of peak performance. ... [W]e show that even when run in the most controlled of circumstances, small, deterministic, widely studied microbenchmarks often fail to reach a steady state of peak performance on a variety of common VMs. Repeating our experiment on 3 different machines, we found that at most 43.5% of ⟨VM, benchmark⟩ pairs consistently reach a steady state of peak performance."

Same arrangement Fedex Ground had. The associate you mention is Amazon middle management in an arrangement meant to avoid employee classification.

> The Ninth Circuit focused on FedEx’s control of the drivers despite the operating agreement referring to them as “independent contractors.”

> “As a central part of its business, FedEx Ground Package System Inc. contracts with drivers to deliver packages to its customers,” the court wrote in its opinion.

> “The drivers must wear FedEx uniforms, drive FedEx-approved vehicles and groom themselves according to FedEx’s appearance standards,” the opinion continues. “FedEx tells its drivers what packages to deliver, on what days, and at what times. Although drivers may operate multiple delivery routes and hire third parties to help perform their work, they may do so only with FedEx’s consent. FedEx contends its drivers are independent contractors under California law. Plaintiffs, a class of FedEx drivers in California, contend they are employees. We agree with plaintiffs.”

> The court said the amount of control used by FedEx ranged from the dimensions of packing shelves on trucks to the appearance of drivers — down to their clothing choice of shoes and socks. It also said FedEx offers a “business support package” which provides drivers with uniforms, scanners and other equipment. The package is optional, but 99% of drivers purchase it, according to the court, and scanners drivers must use in package delivery are not readily available from other sources.

This jives pretty closely with every Amazon driver I've spoken to. Amazon exerts too much control over the work being done for it not to be classified as an employee relationship, and their entire last mile experience for the customer depends on such control. Amazon is also responsible for designing the truck you must drive as an Amazon driver.

IANAL, just making observations based on past legal precedent, current public policy, and anecdotes from Amazon workers I intentionally interact with to get ground truth.

Barrier to entry for duplication, honestly. Anyone can copy-paste a JPEG. Duplicating a Da Vinci requires time, money and skill.

Further, digital art is reproducible at 100% fidelity, whereas any duplicates of physical art will be distinctive not just in their provenance but also in their physical characteristics.

I guess my question to you is: how is this any different than a watermarked JPEG signed with a PGP key?
I've tried many stacks*. My current favorite is Django + PostgreSQL. Every time I use Django I get surprised at how productive it makes me. The built-in admin is fantastic (easily customizable), and almost any question I have is answered in the docs (which is also fantastic) or by the community.

I don't do front-end; just server-side Django templates. Every time I try to build something on the front-end with JavaScript (either with a framework or vanilla), I get tangled in a huge mess.

* Server side: Node.js, ASP.NET, Django, Rails, Phoenix.

* Client side: React, Vue, Angular, Redux, Mobx, etc.
The article says

> IP addresses, single label domains, and reserved hostnames such as test/ or localhost/ will continue defaulting to HTTP.

I don't think this affects you. If you are accessing a device on your LAN, you either use its IP address, or if you use DNS, you must be using your own DNS resolver then. In that case you can just use a single-label domain name such as http://media/ and you can omit the "http://" in that case. This is also the case for many enterprise networks. Tip: you need to enter a trailing slash to tell Chrome is a single-label domain, otherwise Chrome will think you want to search.

I see nothing to worry about.

That Nature story is a great example of the speculation I was talking about in my first post: a sample of "experts", chosen by reporters, repeating opinions.

There's a pretty decent coverage of the level of uncertainty involved, but the reporter still can't resist the urge of "crafting a narrative" that bypasses the uncertainty. For example:

> In May...when some of the strictest lockdowns were in place, health workers noted an abrupt and early halt to the 2019–20 flu season in the Northern Hemisphere. That might partly have been an artefact caused by fewer people coming to a clinic for testing, experts say, but it was also attributable to the effectiveness of policies such as social distancing.

Pretty definitive statement, there. But not even two paragraphs later:

> “Some South American countries haven’t done such a good job controlling COVID, but even there flu is low,” says virologist Richard Webby at St Jude’s hospital in Memphis, Tennessee. “I don’t think we can put it all down to mask wearing and social distancing.” He suspects that the dearth of international travel played a part.

So...yeah. We don't know the answer. The article makes it sound like we do. The headline and photo captions really makes it sound like we know.

Reporters are constantly putting their thumb on the scale by crafting editorially convenient narratives. Richard Webby's opinion doesn't properly emphasize the impact of of social distancing? Bury it under a vaguely definitive-sounding lede, and quote some other "expert" who does agree.

Is there any way to store YouTube videos on IPFS? I want an integration where if I click a YouTube link and it has been removed it loads the video in the standard YouTube page template from IPFS. And http file streaming is fine.

We have an infinite series such as:

S = sum from (i=1) to infinity of [a^i]

we can then multiply by a on each side:

aS = sum from (i=1) to infinity of [a^(i+1)]

Simplify/cancel out to:

aS = S - a

a = S(1 - a)

S = a / (1 - a)

where a = 1 / (1 + R)

so $100 perpetuity with R = 5%:

a = 1 / (1 + 0.05) = 1 / (1.05)

$100 x (1/1.05) / (1 - (1/1.05)) = $100 x 1 / (1.05 - 1) = $100 / 0.05

= $100 / 5%

= $2000

The United States could feed its own population with significantly reduced industrial inputs, particularly if Americans were content to eat only as much meat per capita as e.g. Japanese people [1]. But the United States has over twice as much arable land per capita as the world average:

https://data.worldbank.org/indicator/AG.LND.ARBL.HA.PC

The US is currently one of the world's top exporters of corn, wheat, and soy beans. If the US exported less food then other countries would intensify production further. I don't think that any dietary changes could prevent mass starvation if the world abruptly stopped using artificial nitrogen fertilizers altogether.

Microbial protein production is one of the ways that the world could gradually cut back on artificial nitrogen fertilizers, though. Some chemoautotrophs are capable of assimilating atmospheric nitrogen.

IP addresses and localhost are still exempt from these changes. For development purposes, nothing serious should change; localhost is already a secure context.

I'd very much watch out for using automated tools like these. Many browsers do not check certificate revocation and this leaves your browser open to some extensive MitM attacks. If you use this, you should probably create a second profile (firefox /p to create and pick one) so your normal browsing won't be affected.

In my opinion, it's easier to just type "thisisunsafe" into the warning page once if you use it for developing. If you're demoing your application, putting it on a server with a Let's Encrypt cert shouldn't be too hard either.

I'm sure this has its uses, but I just can't figure out what they would be if you do not wish to take huge security risks.
