Bitcoin fees are skyrocketing

Rising demand has caused Bitcoin’s transaction fees to skyrocket.

The cost to complete a Bitcoin transaction has skyrocketed in recent days. A week ago, it cost around $6 on average to get a transaction accepted by the Bitcoin network. The average fee soared to $26 on Friday and was still almost $20 on Sunday.

The reason is simple: until recently, the Bitcoin network had a hard-coded 1 megabyte limit on the size of blocks on the blockchain, Bitcoin’s shared transaction ledger. With a typical transaction size of around 500 bytes, the average block had fewer than 2,000 transactions. And with a block being generated once every 10 minutes, that works out to around 3.3 transactions per second.

Why Google Is Poised to Hit the Next Critical Milestone in Quantum Computing

MOUNTAIN VIEW, CA—Earlier this week, representatives from automotive and airline companies, big banks, software companies, and the military met to learn the basics of quantum mechanics at NASA. And that was only a small part of it.

Quantum computing software startup QCWare hosted the first quantum computing for business, or Q2B conference, at NASA Ames. Businesspeople seriously considering quantum computing met with experts, entrepreneurs, and professors to learn and see what future quantum computing might have in store for their businesses. There’s been plenty of progress and a lot of hope despite the fact that quantum computing is still in its 1950s, room-sized punch card computing phase. And importantly, conference participants also learned how to realistically judge how “good” a quantum computer really is.

Rumors have swelled that Google will announce “quantum supremacy” soon—essentially, that they will have created a quantum processing device that can solve a problem provably and unequivocally faster than a regular computer can. Such would be a major milestone in the quantum computing world, and Google hinted to some of the details at the conference.

“Press releases always talk about quantum space race in number of qubits,” said John Martinis, University of California, Santa Barbara physicist working with Google on their Quantum Supremacy project. “It’s more than just quantity, it’s qubit quality.” More on that in just a bit.

As a reminder, conventional computers are machines that perform calculations using a series of bits—any physical system whose most basic parts can take on one of two discrete values, like a coin. A quantum computer instead has quantum bits, or qubits. Qubits have some probability of simultaneously being zero or one during a calculation. Quantum computing algorithms perform calculations by manipulating these qubits via the mathematics of quantum mechanics. At its core, that math is just probability combined with complex numbers and the linear algebra you may have learned during your freshman year of college.

The next biggest quantum computing milestone is for some company to show unequivocally that their machine can easily solve problems difficult for a classical computer to solve. Not only does that company need a good quantum computer, but it needs the right problem to stump a classical computer. That problem must be hard, require a lot of high-quality qubits, and be generalizable to any quantum computer, said Martinis.

In Google’s case, the team will set up a quantum circuit with their qubits by entangling them (essentially, setting up a quantum link between them) and then allowing the system to evolve over time. At the end, how the qubits evolve is set by the rules of quantum mechanics, but the final measurement could take on different values with different probabilities. Figuring out the possible outcomes of the qubits, alongside the probability of measuring the outcomes, is so complex that the classical computer needs to simulate the quantum computer in order to do so, and might take weeks to do what the quantum computer can do in minutes.

This problem will offer the researchers a metric that can demonstrate not only that the quanutm computer has too many qubits to simulate classically, but also require the qubits to be good ones. That means they can’t produce the wrong value or turn into regular bits by interacting with the environment or other qubits for a long time. There are other quantum supremacy problems, too. These problems aren’t that useful for industry, but test the limits of regular computing and even the limits of quantum mechanics. And since they require the most advanced classical computers running their fastest algorithms for comparison, these problems will help push the boundaries of regular computing, too.

Google is in the midst of fabricating their 49 or 50 qubit quantum supremacy device this month, and will begin testing in two weeks (not taking Christmas vacation delays into account), said Martinis. But there are other kinds of quantum computers based on different architectures. One startup, IonQ, will use atoms trapped by lasers. Microsoft is working on a different kind of “topological” qubit based on the behaviors of many electrons, and longtime quantum computing business D-Wave uses a specialized system called quantum annealing to perform optimization problems.

Companies like Volkswagen, Airbus, Citibank and Emerson, European IT giant Atos, as well as venture capital firms were present to hear the presentations, and how potential applications like optimization and machine learning could help their businesses.

It’s clear to all that businesses won’t be able to take advantage of quantum computing for quite some time, maybe decades. But just know that people are thinking about this and all the different ways we might be able to use these computers. And you should expect to see companies hit some more major quantum computing milestones soon.

After all, we’re in the midst of entering a new era of quantum computing called the NISQ era, for Noisy, Intermediate-Scale quantum computer, explained John Preskill, CalTech theoretical physicist. But eyes are on the prize: a general purpose quantum computer. Fault tolerance, creating high-quality qubits (often from many physical qubits) that don’t error out, is what many are focused on as much as they are on the number of qubits. Preskill said “Progress towards fault tolerant quantum computer must continue.”

Puerto Rico’s Humanitarian Crisis Takes on New Urgency With Alarming Death Counts

The U.S. government says 62 people in Puerto Rico have officially died in the aftermath of Hurricane Maria. Not many people are buying that given the island’s lack of electricity, healthcare access, and clean drinking water.

To account for this discrepancy, media outlets have been making an extra effort to uncover the true extent of death on the island. Their conclusion? That 62 should be closer to 1,000.

Publications like Latino USA and The New York Times released their own analyses on Thursday and Friday, respectively, after looking at how mortality data in September and October from the Demographic Registry of Puerto Rico compares to 2015 and 2016. The Times found that 1,052 more people died than usual. The numbers are especially high on the days immediately following September 20, when Maria hit the U.S. territory.

Cities like Manatí, Jayuya, and Aguadilla saw some of the highest death rates.

In September, the island saw a major spike in deaths from sepsis, an extreme body response to infection that attacks tissue, which the Times attributes to delayed medical treatment or poor conditions in homes and hospitals. Puerto Rico has been dealing with a range of health care crises since the hurricane, and getting people proper, timely treatment has been a challenge.

The leading causes of death were diabetes and Alzheimer’s. As Times reporter Frances Robles noted on Twitter, insulin is supposed to be refrigerated.

According to the Food and Drug Administration, the drug can lose its effectiveness when exposed to extreme temperatures. And Puerto Rico was in the 90s after the storm.

The Puerto Rican government can keep blaming this rise on coincidence, but advocates, lawyers, and physicians are taking matters into their own hands.

A delegation of more than 30 people in Washington, D.C., on Thursday presented a petition before the Inter-American Commission on Human Rights to address the human rights issues on the island post-Maria. Among the requests? That the commission halt fiscal austerity measures the U.S. has imposed on Puerto Rico due to its debt crisis, as well as the repeal of a federal law—PROMESA—passed to aid with the crisis.

The commission likely won’t respond for another few days, but Commission President Margarette May Macaulay did note the commission would send a formal request for the United States to conduct an on-site visit to Puerto Rico as soon as possible next year.

This came after the commission heard testimony after testimony about life on the island. More than two months since the hurricane hit the island, things should be getting back to normal, right? However, many of these U.S. citizens are still struggling to find normalcy and the island isn’t even meeting 70 percent of its energy output.

Those who testified talked about coal ash contamination in the South, which they’ve received no update about from the government. They don’t know for sure whether a five-story-high coal ash pile has leaked into their water supply— but they do know the government did nothing to prevent that. The pile was left uncovered during Hurricane Maria. They discussed the exacerbated poverty their pueblos are seeing after the hurricane, as well as the ongoing inability from local hospitals to help their sick relatives.

“We have a problem in Puerto Rico, and it’s one of discrimination,” said Annette Martínez Orabona, director of the Caribbean Institute for Human Rights, in Spanish, her voice breaking. “It’s about discrimination that stems from our colonial relationship because we haven’t been given the opportunity to practice our right to self-determine, and that should remain clear.”

The commission heard what both sides had to say, but Puerto Rican officials didn’t send a representative to attend the meeting alongside other U.S. government reps. Maybe they’re too busy trying to update the official death toll?

Macauley was obviously curious herself about this, asking why. Interim Permanent Representative at the U.S. Mission to the Organization of American States Kevin Sullivan, the only U.S. official to speak during the hearing, wouldn’t elaborate why not a single Puerto Rican official could attend this human rights hearing. He simply said they reached out to ask Puerto Rican officials for input and received a letter, which wasn’t read.

“It is very unfortunate that these things are happening, which we call natural disasters, but which are, in fact, man-made because we’ve destroyed our world. And we continue to do so,” said Macaulay, as she closed out the meeting. “It would be good for us to wake up and smell the roses instead of smelling chemicals.”

Videos Of NASA Testing Its New Shape Memory Alloy Tires

These are several videos of NASA testing out its new shape memory alloy tires for use on future trips to distant planets that will probably never happen. The tires are constructed out of a titanium-nickel alloy, and can return to their original shape after being deformed by rolling over a rock or the leg of a jaywalking alien. This isn’t a crosswalk buddy, can’t you read the signs?! Whoa — okay now, let’s put the laser blaster away. Oh God, oh God, please don’t kill me! *shaking head* Whew — it was a just a daydream. “Are you okay, GW?” Why wouldn’t I be? I’ve never been okayer. “Because you’re crying.” It was just so vivid.

Keep going for the the video above of a Mars simulation, a video of a tire being tested on a Jeep in the grass, and a more informative minute and a half long video.

FCC Chairman Ajit Pai ‘jokes’ about being a Verizon shill

Many have accused FCC Chairman Ajit Pai of being a telecom shill between his background as a former Verizon lawyer and his determination to ignore all public input (not to mention complaints about comment bots) as he kills net neutrality. And apparently, his attempts at joking about it are only reinforcing those views. Gizmodo has obtained video of Pai trying to roast himself at the Federal Communications Bar Assocation’s annual event, including a pre-recorded skit where an actual Verizon executive (senior VP Kathy Grillo) talks about wanting to "brainwash and groom a Verizon puppet" to become the FCC chairman, with Pai responding that it sounds like an "awesome" idea.

Aside from the jokes falling flat, there are all kinds of problems with the routine. To start, FCC officials shouldn’t be joking about being shills. Whether or not they have industry backgrounds (like former Chairman Tom Wheeler), they’re supposed to take corruption allegations seriously instead of turning them into comedy sketches. The humor fails in part because there’s a painful degree of truth to it — it wouldn’t have come up if Pai weren’t pursuing the exact deregulation policies that major telecoms want. And crucially, telecom executives shouldn’t ever be involved. If anything, Grillo’s inclusion in the skit supports accusations that Pai is on the take, since he’s clearly cozy enough with Verizon to recruit one of its VPs for a gag.

For that matter, why would a Verizon executive agree to appear in a skit that makes light of corruption, especially knowing that the video might become public and damage the company’s reputation? It’s safe to say this is unusual even for a telecom that hasn’t been shy about voicing its political stances and omitting views it doesn’t like. The company appears unfazed about the connection, however, and even seems to endorse it. When asked for comment, Chief Communications Officer Jim Gerace joked that "we never knew Kathy was so funny."

Unfortunately, it’s unlikely that Pai will face any repercussions in the near future. He was recently chosen to serve a second term, and his closeness to the companies he’s supposed to regulate is par for the course at the moment. This just backs notions that Pai is comfortable flaunting his industry ties, and that he won’t be shy about it going forward.

‘MechWarrior 5’ will revolve around co-op and user mods

Piranha Games is starting to open up on what MechWarrior 5: Mercernaries will entail after a year of teasing, and it’s good news if you don’t always want to play alone. The robot battler should launch in December 2018 with co-op play as a central feature — up to four players can take on the game’s central campaign. Your friends stand in for the AI teammates in your unit, which could be helpful when you absolutely need someone watching your back.

The title will also make a big deal of mod support through Steam Workshop, letting you tailor your own missions, planets and other aspects of the game. Not surprisingly, the game mostly hinges on running your own mercenary company. And if you’re wondering: yes, there’s a good chance the Clans play a role. The game starts in MechWarrior‘s 3015 timeframe and lasts for about 35 years, or right as the Clan invasion is in full swing.

There’s still a lot we don’t know about MW5, but for many its mere existence is important. It’s the first MechWarrior game with a single-player mode in over 15 years, and the first new game in the series for over 4 years. For some, it isn’t so much a sequel as it is a return to the franchise’s roots.
