Is Obama really the post-racial candidate?
Lead Fugees rapper and sometime guitarist Wyclef Jean was the first member of his group to embark on a solo career, and he proved even more ambitious and eclectic on his own. As the Fugees hung in limbo, Wyclef also became hip-hop's unofficial multicultural conscience; a seemingly omnipresent activist, he assembled or participated in numerous high-profile charity benefit shows for a variety of causes, including aid for his native Haiti.
The utopian one-world sensibility that fueled Wyclef's political consciousness also informed his recordings, which fused hip-hop with as many different styles of music as he could get his hands on (though, given his Caribbean roots, reggae was a particular favorite). In addition to his niche as hip-hop's foremost global citizen, Clef was also a noted producer and remixer who worked with an impressive array of pop, R&B, and hip-hop talent, including Whitney Houston, Santana, and Destiny's Child, among many others.
Question: Is Obama really the post-racial candidate?
Wyclef Jean: I think that when people look at Obama, they have to stop saying, “Okay, it’s a race,” you know what I mean? Because what happens is when you look at Obama, he’s a man. So it’s like when you look at someone, you gotta get, you know, past the level. Like, look at the debates. He’s an educated man. He has the gift of speaking to people. He has the gift of going anywhere around the world and actually being in a room with someone and looking at them in the eyes and having a conversation. What I love most about Obama -- and this is why you all gotta get past this whole race shit, period, Clef said so. What I love most about Obama is Obama says, “We gotta get off this high horse that we on and start to deal with things direct.” And I think to move forward as a race and as people, we have to start doing that.
Get off your high horse, Wyclef says.
Why self-control makes your life better, and how to get more of it.

- Research demonstrates that people with higher levels of self-control are happier over both the short and long run.
- Higher levels of self-control are correlated with educational, occupational, and social success.
- It was found that the people with the greatest levels of self-control avoid temptation rather than resist it at every turn.
Ready your Schrödinger's Cat Jokes.
- For a time, quantum computing was more theory than fact.
- That's starting to change.
- New quantum computer designs look like they might be scalable.
Quantum computing has existed in theory since the 1980's. It's slowly making its way into fact, the latest of which can be seen in a paper published in Nature called, "Deterministic teleportation of a quantum gate between two logical qubits."
To ensure that we're all familiar with a few basic terms: in electronics, a 'logic gate' is something that takes in one or more than one binary inputs and produces a single binary output. To put it in reductive terms: if you produce information that goes into a chip in your computer as a '0,' the logic gate is what sends it out the other side as a '1.'
A quantum gate means that the '1' in question here can — roughly speaking — go back through the gate and become a '0' once again. But that's not quite the whole of it.
A qubit is a single unit of quantum information. To continue with our simple analogy: you don't have to think about computers producing a string of information that is either a zero or a one. A quantum computer can do both, simultaneously. But that can only happen if you build a functional quantum gate.
That's why the results of the study from the folks at The Yale Quantum Institute saying that they were able to create a quantum gate with a "process fidelity" of 79% is so striking. It could very well spell the beginning of the pathway towards realistic quantum computing.
The team went about doing this through using a superconducting microwave cavity to create a data qubit — that is, they used a device that operates a bit like a organ pipe or a music box but for microwave frequencies. They paired that data qubit with a transmon — that is, a superconducting qubit that isn't as sensitive to quantum noise as it otherwise could be, which is a good thing, because noise can destroy information stored in a quantum state. The two are then connected through a process called a 'quantum bus.'
That process translates into a quantum property being able to be sent from one location to the other without any interaction between the two through something called a teleported CNOT gate, which is the 'official' name for a quantum gate. Single qubits made the leap from one side of the gate to the other with a high degree of accuracy.
Above: encoded qubits and 'CNOT Truth table,' i.e., the read-out.
The team then entangled these bits of information as a way of further proving that they were literally transporting the qubit from one place to somewhere else. They then analyzed the space between the quantum points to determine that something that doesn't follow the classical definition of physics occurred.
They conclude by noting that "... the teleported gate … uses relatively modest elements, all of which are part of the standard toolbox for quantum computation in general. Therefore ... progress to improve any of the elements will directly increase gate performance."
In other words: they did something simple and did it well. And that the only forward here is up. And down. At the same time.
These modern-day hermits can sometimes spend decades without ever leaving their apartments.
- A hikikomori is a type of person in Japan who locks themselves away in their bedrooms, sometimes for years.
- This is a relatively new phenomenon in Japan, likely due to rigid social customs and high expectations for academic and business success.
- Many believe hikikomori to be a result of how Japan interprets and handles mental health issues.
