刺蝟

Posted on by

The phrase hedgehog’s dilemma refers to the notion that the closer two beings come to each other, the more likely they are to hurt one another; however if they remain apart, they will each feel the pain of loneliness.

This comes from the idea that hedgehogs, with sharp spines on their backs, will hurt each other if they get too close.

This is analogous to a relationship between two human beings. If two people come to care about and trust each other, something bad that happens to one of them will hurt the other as well, and dishonesty between the two could cause even greater problems.

Origin

The concept originates from Arthur Schopenhauer’s Parerga und Paralipomena, Volume II, Chapter XXXI, Section 396. In his English translation, E.F.J. Payne translates the German “Stachelschweine” as “porcupines”. Schopenhauer’s parable describes a number of hedgehogs who need to huddle together for warmth and who struggle to find the distance where they are warm without hurting one another. The hedgehogs have to sacrifice warmth for comfort. The conclusion that Schopenhauer draws is that if someone has enough internal warmth, he or she can avoid society and the giving and receiving of irritation that results from social interaction.

It is also important to note that hedgehogs do not actually hurt each other when they get close, human beings tend to keep themselves more “on guard” in relationships and are more likely to sting one another in the way that a relaxed hedgehog would if spooked. When living in groups, hedgehogs often sleep close to each other.

時空幻境 3

Portal is a 2007 single-player first-person puzzle-platform video game developed by Valve Corporation.

The game primarily comprises a series of puzzles that must be solved by teleporting the player’s character and simple objects using “the handheld portal device”, a device that can create inter-spatial portals between two flat planes.

The game’s unique physics allows momentum to be retained through portals, requiring creative use of portals to maneuver through the test chambers.

Now, the common paradigm is that the teacher-student ratio is critical — fewer students means higher-quality teaching. But if you turn your students into teachers, you gain leverage. You move the fulcrum over.

何必偏偏玩謝我

Posted on by

Charlie Kaufman

.

Do I have an original thought in my head? My bald head. Maybe if I were happier my hair wouldn’t be falling out. Life is short. I need to make the most of it. Today is the first day of the rest of my life. I’m a walking cliche. I really need to go to the doctor and have my leg checked. There’s something wrong. A bump. The dentist called again. I’m way overdue. If I stop putting things off I would be happier. All I do is sit on my fat ass. If my ass wasn’t fat I would be happier. I wouldn’t have to wear these shirts with the tails out all the time. Like that’s fooling anyone. Fat ass. I should start jogging again. Five miles a day. Really do it this time. Maybe rock climbing. I need to turn my life around. What do I need to do? I need to fall in love. I need to have a girlfriend. I need to read more. Improve myself. What if I learned Russian or something, or took up an instrument. I could speak Chinese. I’d be the screenwriter who speaks Chinese and plays the oboe. That would be cool. I should get my hair cut short. Stop trying to fool myself and everyone else into thinking I have a full head of hair. How pathetic is that. Just be real. Confident. Isn’t that what women are attracted to? Men don’t have to be attractive. But that’s not true. Especially these days. Almost as much pressure on men as there is on women these days. Why should I be made to feel I have to apologize for my existence? Maybe it’s my brain chemistry. Maybe that’s what’s wrong with me. Bad chemistry. All my problems and anxiety can be reduced to a chemical imbalance or some kind of misfiring synapses. I need to get help for that. But I’ll still be ugly though. Nothing’s going to change that.

Chrono Trigger 3

Posted on by

.

Masato Kato confirmed that Cross featured a central theme of parallel worlds, as well as the fate of Schala, which he was previously unable to expound upon in Chrono Trigger. Concerning the ending sequences showing Kid searching for someone in a modern city, he hoped to make players realize that alternate futures and possibilities may exist in their own lives, and that this realization would “not … stop with the game”.

Ra’s al Ghul

Planned cast

Bale said he would return if Nolan did. Aaron Eckhart had expressed his enthusiasm to return for a sequel if asked, although he later stated Nolan verified that his character, Harvey Dent, is dead. Nolan confirmed that the ensemble cast from the first two films will be returning. Tom Hardy and Anne Hathaway have been cast as Bane and Selina Kyle. Juno Temple has been cast in a role described as a “street-smart Gotham girl”. Josh Pence was cast as a young Ra’s al Ghul, with his scenes to take place thirty years before the events of Batman Begins. Nestor Carbonell is in negotiations to reprise his role as Mayor Anthony Garcia. Joseph Gordon-Levitt has been cast as John Blake, “a Gotham City beat cop,” along with Marion Cotillard, who will be portraying Miranda Tate, “a Wayne Enterprises board member eager to help a still-grieving Bruce Wayne resume his father’s philanthropic endeavors for Gotham”.

Teachers 4

Posted on by

.

I’m about to become a teacher. How can I be a good one?

The best teachers I remember from school had three things in common:

(1) They had high standards. Like three year olds testing their parents, students will test teachers to see if they can get away with low-quality work or bad behavior. They won’t respect the teachers who don’t call them on it.

(2) They liked us. Like dogs, kids can tell very accurately whether or not someone wishes them well. I think a lot of our teachers either never liked kids much, or got burned out and started not to like them. It’s hard to be a good teacher once that happens. I can’t think of one teacher in all the schools I went to who managed to be good despite disliking students.

(3) They were interested in the subject. Most of the public school teachers I had weren’t really interested in what they taught. Enthusiasm is contagious, and so is boredom.

No, because I think we didn’t know what we were doing. I think the hallmark of a really good entrepreneur is that you’re not really going to build one specific company. The goal — at least the way I think about entrepreneurship — is you realize one day that you can’t really work for anyone else. You have to start your own thing.

Great Idea 4

Posted on by

.

If so, this is good news indeed. Good ideas always tend to win eventually. The problem is, it can take a very long time. It took decades for relativity to be accepted, and the greater part of a century to establish that central planning didn’t work. So even a small increase in the rate at which good ideas win would be a momentous change — big enough, probably, to justify a name like the “new economy.”
