I have not tried in a bit...last time was 2 days. I have heard they had a backlog due to the withdrawl shutdown but of course that is speculation unless I try to transfer today and see how long it takes.
I think we're talking about parties who don't actually have an order in. Rather they have automated a process to enter orders in response to certain conditions. Depending on what those conditions are, you won't be able to rely on a continuous price trajectory.
Admittedly, I don't see how this is different for BTC than it would be for any other asset.
Those are not providing liquidity in a useful sense right now. Usually the measure is people prepared to trade at current bid or offer ie a very narrow measure. If you want to buy at 1% down that's not useful now.
I searched for Acura MDX alarm antenna location and a quick glance tells me that the antenna is located behind the glovebox. So I would guess it probably works better from that side of the car...notice they seem to have to get very close to the car.
Where Khan Academy has the distinct advantage to me is not in its content or teaching style (both of which seem good) but in the ability for the student who does not grasp the subject to be able to replay the lesson over and over without fear of holding up the class or causing the teacher inconvenience thereby allowing the students who do understand the ability to move on to the next subject without having to "read ahead". The overall content covered can be greater overall in a shorter amount of time.
Kids don't want to seem different from other kids. If a child has to ask the teacher to repeat the lesson or stay after for extra help he may be perceived by his peers (or feel as though he is being seen as) as slower or stupid. With KA on the other hand the student can learn at his own pace...something that just cannot be done in a class of 30+.
Khan Academy does not get upset if a student does a search and finds another method to solve the problem at hand (I don't know how many times I was told "I don't care if you are getting the right answer, we want you to do it our way" when I was in school).
To me it is not about KA at all...but more about self education. The best teacher is you, the lecturer may be giving you the information but how you perceive and use it is entirely based on you. It is a simple fact that teachers cannot at the same time be paid more and have smaller class sizes...the funding is not there. Students are going to fall behind unless they are taught early on to not rely entirely on the teacher to show them "everything". We have at our disposal the most powerful learning tool in the history of man...The internet. No longer are libraries bound to the confines of a building down the road that you may or may not have access to. This is the most amazing thing to me, decentralization of learning, and those who profit from learning in the old system obviously are going to be worried about their future income.
I work in a small start-up making educational software, and this is exactly the kind of thing I want to achieve.
A couple of months back I read John Holt's famous book 'Why Children Fail' which had a profound effect on me and my work. What he says, and what I agree with due to my own experience and observations is that school can be a fundamentally scary experience for children. Self-esteem is so central to learning, because how you react to failure and your own progress (or lack thereof) defines the way you learn. Kids who are afraid of looking stupid, of being compared to their peers, and of having to work hard without the promise of success are the ones who are branded as lazy, unimaginative, or just 'stupid', when in fact they are just afraid of trying hard.
The internet and self education offers an opportunity for kids to escape that fear, and to truly experience the joy of learning. I'm sure many HN readers will relate to my belief that the greatest joy of hard work is not when you appear smarter or harder working than others, but when you achieve something for yourself, or learn something new. Many programmers get to experience that joy all the time.
Holt became so disillusioned with the inability of schools to provide a comfortable and secure learning place for children that eventually he became an advocate for home schooling. I believe in schools' potential and what teachers have to offer, and my company's software is built accordingly, but we have reached a point where there is too much focus on comparing students; through frequent nation-wide testing, intense competition for prestigious colleges, and through insecure parents who push their children an unhealthy amount. To balance that, the schooling system has lost sight of the original reasons for its existence. The judgment-free zone of the internet and self directed learning is giving us a chance to undo the bad learning habits of our current students, and ensure that the next generation of students do not ever need to learn them.
The Khan academy is not about taking the power away from schools and administrators, it is about putting the emphasis back on why we have them in the first place; which is because for all the good of self education, the greatest help you can give a student is a teacher who understands them and the way they learn.
I used to tutor math at a community college. I did mostly the basics: lots of algebra, very occasionally a little calculus. I learned two things.
First, it was usually the assumed knowledge that got them. They'd mess up at calculus because of algebra; or get algebra wrong because they couldn't add. When you don't know the basics, you get the wrong answer even when you do all the new stuff right. The whole thing starts to seem futile, like climbing a mountain of sand.
Second, just as above. Most of my students had no idea that math, like weightlifting, is supposed to hurt a bit. They thought that heavy, stretching sensation you get when you learn new concepts meant they were stupid, that they couldn't do math. They didn't realize that every feels that, if only briefly. If you're in the bottom third of the distribution, and a third of people are, you never get to the other side of that feeling before the class moves on.
The answer isn't magic teachers. It's for kids to learn that learning is possible. You do that with practice, and feedback, until they get it right.
I tutored some adult basic education for a bit...helping people get their HSE/GED. Some of these people had tried to pass the pretest many times and were stuck at fractions. Over and over they failed the tests. I kept hearing "I just can't get this" or "It makes no sense". One of the other TA's and I were discussing it and we realized that a lot of these people were people who had "been around drugs" in their life. So we decided to handle things this way. We went to them with a problem like "5/8 + 1/4"...to which they would respond "I don't know"...then we said "You have bought weed before right?" "yes" is the response. Well...if you have 7/8 of weed and you add another quarter ounce what do you have. Every time...the got it immediately. The teachers came back to us and asked what we had done differently...we explained. They said they really didn't approve but it was working.
It is all about relating things and explaining in a way that can be easily referenced in your mind.
By the way...several of these people who could not pass the TABE tests at the time went on to get their GED's because of that one little step with fractions.
I prefer Reprap. Save the money and spend it developing new expansions. My original Mendel has a 210x210x136mm build area and that is pretty much stock. Nophead's Mendel90 is soon to be released and appears to be a very stable and scalable design.
I went to public school in Coeur d'Alene and I currently live in Post Falls. I can say that we need more tech in the classroom. There is not enough of a local push for moving things forward, people are mystified by computers and very few over the age of 35 here know anything more than using it for the web or checking emails, things are better than they were but it is even hard to find a mechanic that doesn't say they "hate these new computerized cars" (even though it is old tech by my standards).
The elementary schools here when I went to school in my opinion were moderate. I have more memories of teachers trying to correct my poor handwriting or chastising me for reading ahead of the rest of the class in my books than I do of anyone actually trying to figure out what I was interested in. By middle school my standardized test scores (Iowa tests) put me in the 95-99th percentile in the nation (I took the SAT's in the 7th grade because of it)...by my junior year in high school the vice principal said to me "...why don't you just drop out? You don't want to be here and we don't want you here" That principal was Steve Casey...winner of many awards for education in the area. That is just an example of the system up here.
I approve of the pay by performance idea for teachers and I think tech should be funded before athletics since that is what truly will push innovation and bring us out of the recession that we are in.
I thought I recognized this rant...same one that has been repeated for the last 2 months in the BTC forums. Miners don't care...I should know, I am one...and given my current power cost I may be one of the last. I will start worrying about mining profitability when Vladimir starts shutting down one of his 3 data centers...since he pays 7 times the power I do. At that point folding@home or seti gets my GPU cycles...that is if nobody figures a better way to profit from leasing these machines for other than bitcoin use (legal ways that is).
