Tap the Yellowstone Super-volcano!

1 Share

I applaud this kind of big think!

The USA is confronted with three epic-size problems: (1) the need for production of energy on a scale that meets the current and future needs of the nation, (2) the need to confront the climate crisis head-on by only producing renewable, green energy, that is 100% emission-free, and (3) the need to forever forestall the eruption of the Yellowstone Supervolcano. This paper offers both a provable practical, novel solution, and a thought experiment, to simultaneously solve all of the above stated problems. Through a new copper-based engineering approach on an unprecedented scale, this paper proposes a safe means to draw up the mighty energy reserve of the Yellowstone Supervolcano from within the Earth, to superheat steam for spinning turbines at sufficient speed and on a sufficient scale, in order to power the entire USA. The proposed, single, multi-redundant facility utilizes the star topology in a grid array pattern to accomplish this. Over time, bleed-off of sufficient energy could potentially forestall this Supervolcano from ever erupting again. With obvious importance to our planet and the research community alike, COMSOL simulation demonstrates and proves the solution proposed herein, to bring vast amounts of green, emission-free energy to the planet’s surface for utilization. Well over 11 Quadrillion Watt hours of electrical energy generated over the course of one full year, to meet the current and future needs of the USA is shown to be practical. Going beyond other current and past research efforts, this methodology offers tremendous benefits, potentially on a planetary scale.

50 Top U.S. Pizzerias Announced

1 Comment
A Neapolitan pizza with a puffy crust, tomato sauce, grated cheese, and basil from Una Pizza Napoletana in New York City
The excellent “Cosacca” from Una Pizza Napoletana.

Italy’s “50 Top Pizza” organization has just published their list of the top 50 pizzerias in the U.S. They’ve been ranking pizzerias all over the planet for years, but this is only the second time they’ve zoomed in on the U.S. Last year’s announcement came via an online event due to COVID protocol, but this year’s announcement was live and in person in NYC’s Chelsea neighborhood. The big winner was Una Pizza Napoletana, an absolutely epic pizzeria that has moved from East Coast to West Coast and back over the past 2+ decades. It recently resettled in NYC’s Lower East Side after a pandemic suspension.

New York City faired well on the list, with 9 pizzerias in the list, followed by San Francisco and Portland (Oregon). I’ve only been to half of the spots on the list so it looks like I have some homework to do!

I’m Bored of Lists

While I love anything that stirs up conversation about pizza, I have to admit I’m completely bored of lists. The more lists I see, the less I care about them. It seems like every week we get a new one. Most lists are just regurgitations of old ones, compiled by interns who spend 10 minutes searching “best pizza” before hitting the publish button. I don’t see any value in most lists because they offer nothing new. I saw a list a few weeks ago from a reputable website that offered inaccurate information that would have been avoided had a journalist actually visited the pizzerias.

My favorite list used to be the Daily Meal’s 101 Best Pizzeria in America. Until recently, Arthur Bovino produced the list by tapping dozens of experts to compiled this beast of a list. The methodology of this list changed up a year or two ago and now it’s just like all the others. There’s a similar list in Daniel Young’s massive Where To Eat Pizza, in which he pulled together experts in cities across the planet (I helped with the NYC section) to poll their own local contacts in advance of compiling a brick of a book with listings and information about each spot.

My Thoughts on the Top 50 List

To understand a list, you need to know who wrote it. This list comes to us from an Italian organization. They truly are experts and devotees of pizza as a craft. They have the deepest love for the food and I have a great deal of respect for that. Knowing this explains why the list is heavily weighted toward Neapolitan and other styles with Italian influence. I’m taken aback at how a list of U.S. pizzerias is missing so many American styles. I don’t see some of my New York favorites like L’industrie, Scarr’s, Patsy’s, and King Umberto. I don’t see any of the non-Neapolitan styles from Chicago. Nothing from Detroit. Nothing from New Haven. It’s strange to have a U.S. list missing so many U.S. styles.

Knowing who wrote a list is a prerequisite for understanding what a list means. This is a great list when you understand who wrote it. It’s an incomplete list if you take the headline as fact.

Selecting the 50 top pizzerias in the U.S. is a huge task that I wouldn’t dare undertake. I don’t know the full story behind how it’s assembled and I’m hoping to figure that out so I can continue to understand and talk about this list when it inevitably comes up on tours.

Right to Repair!

1 Comment and 4 Shares

"Apple shipped me a 79-pound iPhone repair kit to fix a 1.1-ounce battery. I'm starting to think Apple doesn't want us to repair them."

The thing you should understand about Apple's home repair process is that it's a far cry from DIY. I expected Apple would send me a small box of screwdrivers, spudgers, and pliers; I own a mini iPhone, after all. Instead, I found two giant Pelican cases -- 79 pounds of tools -- on my front porch. I couldn't believe just how big and heavy they were considering Apple's paying to ship them both ways. [...]

But I wasn't done yet. The single most frustrating part of this process, after using Apple's genuine parts and Apple's genuine tools, was that my iPhone didn't recognize the genuine battery as genuine. "Unknown Part," flashed a warning. Apparently, that's the case for almost all of these parts: you're expected to dial up Apple's third-party logistics company after the repair so they can validate the part for you. That's a process that involves having an entirely separate computer and a Wi-Fi connection since you have to reboot your iPhone into diagnostics mode and give the company remote control. Which, of course, defeats a bunch of the reasons you'd repair your own device at home! [...]

Yeah, none of that surprised me. What surprised me was the price tag.

  • $69 for a new battery -- the same price the Apple Store charges for a battery replacement, except here I get to do all the work and assume all the risk.
  • $49 to rent Apple's tools for a week, more than wiping out any refund I might get for returning the old used part.
  • A $1,200 credit card hold for the toolkit, which I would forfeit if the tools weren't returned within seven days of delivery. [...]

Apple can say it's giving consumers access to everything, even the same tools its technicians use, while scaring them away with high prices, complexity, and the risk of losing a $1,200 deposit. This way, Apple gets credit for walking you through an 80-page repair, instead of building phones where -- say -- you don't need to remove the phone's most delicate components and two different types of security screws just to replace a battery.

To me, those giant Pelican cases are the proof. It would cost Apple a fortune to ship 79 pounds of equipment to individual homes all over the country, even with corporate discounts. [...] It would cost us upwards of $200 just to return those cases to their sender. Yet Apple offers free shipping both directions with your $49 rental.

Previously, previously, previously, previously.

Basically, Apple sends you the tools that Apple uses to do these jobs, at the price that Apple charges for doing those jobs. Unfortunately, the reason that people want Right to Repair is because Apple's prices are too high, and Apple's methods of repair are too inefficient, if you could just get individual components instead of entire assemblies, then you could get the repair done at a price that makes sense, rather than being nearly the cost of a new phone.

Java Cryptography Implementation Mistake Allows Digital-Signature Forgeries

1 Share

Interesting implementation mistake:

The vulnerability, which Oracle patched on Tuesday, affects the company’s implementation of the Elliptic Curve Digital Signature Algorithm in Java versions 15 and above. ECDSA is an algorithm that uses the principles of elliptic curve cryptography to authenticate messages digitally.


ECDSA signatures rely on a pseudo-random number, typically notated as K, that’s used to derive two additional numbers, R and S. To verify a signature as valid, a party must check the equation involving R and S, the signer’s public key, and a cryptographic hash of the message. When both sides of the equation are equal, the signature is valid.


For the process to work correctly, neither R nor S can ever be a zero. That’s because one side of the equation is R, and the other is multiplied by R and a value from S. If the values are both 0, the verification check translates to 0 = 0 X (other values from the private key and hash), which will be true regardless of the additional values. That means an adversary only needs to submit a blank signature to pass the verification check successfully.

Madden wrote:

Guess which check Java forgot?

That’s right. Java’s implementation of ECDSA signature verification didn’t check if R or S were zero, so you could produce a signature value in which they are both 0 (appropriately encoded) and Java would accept it as a valid signature for any message and for any public key. The digital equivalent of a blank ID card.
