It's tough beginning teaching. I teach some science classes to grad students (who I've actually been incredibly impressed with, so my experience is a bit different). Here are a few of my thoughts/questions:

-First, thanks for your teaching. It's a tough job. I suspect this particular class will get better, and the fact you're trying to do a great job for these students comes through loud and clear from your post.

-How do you personally feel about the course material? Are you personally interested in it and enthusiastic about it? If not, it'll be hard to get others interested and it's tough to fake it. If you are, are you communicating that passion?

-Have you asked for someone to observe a class or two? Or videotaped a class for your own review? There may be some subtle things that you're not even aware of that's detrimental - extra eyes or seeing yourself teach can be revealing. What feedback is your TA giving you?

-Maybe the audience actually is wrong. I'm a big believer in "no bad students, just bad teaching", too, but I suspect we're dealing with a low N here...it's conceivable you're doing everything well and your first calculus class is just not that into the material for any number of reasons. Although you didn't say, I'm assuming this freshman calc class isn't necessarily filled with math majors.

-Great job on soliciting feedback from students - I assume you did something more than the same old dry "evaluations" we hand out and sometimes just skim over.

-Are students coming to your office hours? If not, why not? In some classes, I've set up appointments with each student at least once a semester, just so I have a chance to know them and their own motivations/plans/strengths, etc. It tends to work well. It's another great time obviously to ask them each what's working and not working in a more personal setting.

Again, thanks for your teaching and your obvious desire to improve things for your students.
Googles SEO chief Matt Cutts is often on HN defending Google and explaining their fair search algorithm,

Since it is already proven how they manipulated the Yelp search results - the company that Google wanted to buy ,

and it has also been discussed that Google Places and other Google sites are un-naturally high among the first search results ,

may be its time to forget about their fair algorithm and start discussing to what extent they manipulate search results to prefer their own companies ( Google Places, Zagat etc. )

- and may be some Google people have some explaining to do to their customers why are the Google products spam results on the first page too often , so that customers do not start to use DuckDuckGo.com
I guess I just look at these things and say, "Yeah doesn't surprise me CSS could do that, but is it done well?" We're at a point where none of this is surprising or amazing to me, it just makes sense. I'm looking for quality.

I found the business model talk to be the most interesting; not heard it discussed before.

When I was first out of school, my first interview wanted to see my transcript, so I gave them an unofficial copy. The hiring manager in charge mentioned that they were not really even looking at the grades, just the classes completed. This was not in the valley; rather, a defense contractor in the US southwest.

One thing I wonder about, though, is the student gets a free ride scenario. That sounds like it would be the worse case for many other universities. If everyone who was qualified to get into Stanford can now go there, why go anywhere else? Will local universities used as local co-working and lab spaces? Will some of them just go away entirely or become hybrid campuses where lab work qualifies for credit at both Stanford and the host campus?

The co-working part is OK with me. I often had conversations like, "Hey, that socket stuff is hard, I keep getting problem XYZ." "It is rough. I got around it with fix ABC." Building stuff together was more valuable than listening to the same lecture together.
Cairns Hostels and hostels
Yes, it is certainly easier to audit than binaries, but one of the main axioms in cryptography is, that it should ensure security for the timeframe until the information protected is still valuable (one can assume, that eventually all crypto is cracked -- the question is when, and how to delay this to ensure functionality).

This bug was injected for two years: the damage has been done, with literally over a million of weak keys that pollute the internet. That said, I acknowledge, that the ssl system has (perhaps even more) serious weaknesses beyond the keys themselves. It should have been caught days after commit, and never should have made it into debian stable (and debian has a very slow, thorough release cycle). But telnetd comes to mind, etc. Perhaps only OpenBSD shows consistent true efforts in open source auditing.
Caterina Fake's 2012 Resolution: Make technology more human
As the article says they are betting that with all the other solar capacity going online the peak price (demand vs supply gap) will be late afternoon early even when demand is still high but there is little/no sun.

I assume you mean $200/megawatt-hour which is close to the numbers I get. I guess they are assuming the peak-premium plus the renewable requirements will offset the premium price. They probably have a longer payback period too.

No, I am saying the administration is expertly farking with public perception.

I am aware of their want to ensure their power was protected.

I am saying that most people are being played to think that obmama expressed "concerns" but was painted into a corner where he needed to sign this. The fact is they ADDED / ENSURED the clauses they wanted were in there, then played the perception of the signage to make it look like they were the VICTIM rather than the perp.

There is a very very good reason obama is a constitutional lawyer as potus.

Why use a grid of characters and not a grid of pixels (with indexed values that can be linked to the properties just like UTFGrid links chars to properties) ?

I use this kind of pixel grid which brings those advantages, especially for very large maps :

- use of the image (with carefully chosen colors) as a direct preview of the map (depending on the resolution)

- efficient (bidirectional) PNG compression

- use of already present image manipulation libraries for all kind of manipulation (like layers addition)

What's the benefit of using UTF characters ?

I was just working on something like this for a coding competition. Players submit code to compete head to head. Sandboxing is required to prevent players from modifying the game state and/or the other players' state. That's just one example that comes to mind...
One thing that many commentators seem to ignore is what exactly the PISA tests measure. For example, the PISA math problems (http://www.pisa.oecd.org/dataoecd/38/51/33707192.pdf) are very specifically meant to assess how well students can solve pretty easy problems that could occur in their lives and where basic math literacy is needed, and the PISA exam is given to a random sample of all students. Contrast this with the International Mathematical Olympiad (results at http://www.imo-official.org/country_team_r.aspx?code=FIN) which measures how well the very best students do on very hard problems.

It should not be surprising that an education system emphasizing social equality instead of individual excellence performs well when you measure how well the average student does on an easy problem. It just shows that Finland's and PISA's values align well with each other.
My best calculus professor I had, the course was 3 hours with two 15 minute breaks in between, twice a week, tues/thurs. The first half was spent going over homework assigned the previous class. He would answer every question no matter how fundamental it was and go back to basics if it was necessary for instance synthetic division, or identity substitution. After he went over the homework problems, he would only go over the problems which were given answers to(in the book), we would cover new material and this would be repeated until we had a test, which was usually roughly ever 5 classes, so every 3rd week was a new exam. But by the time you got to exam time, you had a pretty good grasp on the material. The key for me was that he picked problems in the book which I was able to obtain a solutions manual for to help me through the mechanics of the problems. I would only ask for help on problems which were poorly explained in the solutions manual. Ironically the solutions manual was pretty worthless, It just gave you some confidence to move forward since it provided key points in the solutions. I ended up with 2 B's in his Calculus 1 & 2 courses, ended up taking Calc3 & Diff Eq, got A's in both courses because of how i learned in the first 2 calculus courses. Not sure this really helps. Just my experience. In the end, letting me go home to do my work with the perception that I could get a partial understanding of the material when I wasn't in class was a huge deal. Frustrated students don't want to study, unless they can get some help from someone who knows more than themselves. So having access to manuals which help you mechanically solve problems are beneficial until you can get back into class. BTW, I took these courses at a community college.
I agree that this isn't disgraceful at all, but for me the more interesting test will actually be whether or not Louis CK's model will work for other famous live performers.

Did it work because the model is inherently sound or because it was so novel?

I don't think we can say one way or the other yet.

If I had to guess, I'd say that I think that his model will work for others but probably not as well, once (if?) it becomes commonplace I suspect you'll get a higher ratio of downloaders who don't pay to those that do.
It's actually fairly logicial once you're used to it. It's just a quadrant grid system. Streets run east-west, avenues run north-south. The center of the city is approximately somewhere downtown, streets go out in a radial fashion from downtown.

The drones will become the new 'face' of the US in this possible future. They will still hate us, but they will see us less and less as human beings because most people in the affected areas will only ever be dealing with drones.
My own reaction was amazement at the obsessive detail they had rendered in CSS.

But if you think this is sloppy work, why not try your hand at making something similarly detailed that you feel is done right?
CSS is not optimized for graphics and if you're only interested in something static, in this case for instance the result is bigger than an equivalent PNG file. It also sucks for client-side optimizations in general because rendering CSS takes more processing power than displaying a bitmap.

What it does give you is smooth animations, however I think SVG would be more suited for vector graphics, since it is a format created and optimized for actual graphics and you can export from popular editors (like from Adobe Illustrator) to SVG easily.

Not to belittle this effort though, as this is cool :)
bellvue ave, bellvue court and bellvue place intersect in cap hill.

to answer the OP, those directionals are required to uniquely identify addresses in Seattle: http://en.wikipedia.org/wiki/Street_layout_of_Seattle#Direct...

note that they're prefixes for east-west streets, but suffixes for north-south avenues.

I've lost deliveries before when I've omitted the directional, even if the street #/street name was unique to the zip code.
> Save bandwidth

With a 129kb CSS file I'm not so sure

> Client-side optimization

Depends how you look at optimization... will definitely take a lot more processing to render all that CSS instead of an image

> Easier to update

If you consider mucking with CSS layout properties and doing pixel calculations easier to update than using a program such as photoshop/fireworks, I'm somewhat scared.

Well, that's a perfectly reasonable conclusion to make, in this case. However, his business just seems to be the wrong one to use this model on. For one, there is no added value for paying customers from the free customers being there. For another thing, the rewards for buying into his product just seem.. meager. I know that I wouldn't want to buy any of them.

Though, his comments about the psychology of free users? Spot on, in my opinion.
thanks, read the book a long time ago but guess time to brush up and try and put into practice..

> But that doesn't seem so dystopian. Everyone is a publisher now.

When you think it through, it does seem dystopian. Imagine that e-ink matures, and paper isn't that useful any more. That we no longer purchase dead-tree copies of our books, magazines, and so on. I think that can happen. I read right now a novel on my electronic reader, even though I have a dead-tree copy, because my reader is lighter and slimmer than my book.

Now, how do I lend you a book for which I have no dead-tree copy? I can't give you such a piece of dead-tree (and naturally lose it for myself). All I can do is make a copy and give it to you. And then I'm a publisher. And then what I'm doing is forbidden. And then I can't even lend you my book.

(One could imagine laws/DRM that would erase the copy I own if I ever give another copy to someone else. However, I don't think the IP Lords would want even that. They'd say it harms their revenue.)

But that's not dystopian enough. True dystopia is when the means of enforcing it kick in: the only know way right now is a "total surveillance" regime, where free software itself is forbidden.

Ask HN: I need your advice!
Along with my 2 co-founders, I run a startup called ResearchNation.net, which provides user generated reviews for business intelligence reports (like a TripAdvisor, for Datamonitor, Euromonitor reports).

The problem is, after almost 9 months, we're still getting zero traction. I mean, literally zero.

We don't have any reviews. I'm not entirely sure what to do. My overall assessment is that it's a good idea (real problem to be solved - gauging quality) but we're not sure we can solve it on our own. The 2 partners that could help us solve this problem are publishers and resellers; the former hate us (already gotten 1 hate phone call) and the latter see us as competition. So, basically, left to our own devices, we are stuck. And out of cash now.

Frankly, we're open to pivoting to a completely new idea, and our site lends itself well to becoming an 'Airbnb' of x (not in its present state, because we've hidden a lot of stuff we built originally, but you can take my word on it!).

So here's my question - what ideas do you have for things we could morph into? i.e. Airbnb for 'x'? Or, do you think we should just screw it and shut down. I have to admit I do sort of feel that we've now got a solution/platform, and are in search of a problem...

The most-useful parts might be the constants in the PHP portions, but I have a feeling they're unnecessary, given that they seem to be in the MaxMind database they're using.
Thanks. It's fast.

Your demo displays one problem : the strange choice of labels. For example, look for France's capital at zoom 8. You'll see a lot of small towns indicated but not Paris. And I can reproduce this for a lot of notable towns (like NY).

Nice. An interesting read. I haven't used FubuMVC before but as for rails and other similar web frameworks, the principle is "Convention over Configuration", so you would have certain limits on the way you think.

But the bright side is that this "Convention" has arose from identifying the common problems with web development and coming up with a standard solution which adheres to DRY principle which is another one of the Rails founding principles. The Convention also makes it easier for users to share code helping DRY again. So, if you prefer "Configuration over Convention", you are better off using something else.

What is immoral is those studies, and the data they're supposedly based on.

As to why Finland does so good ... good question. However the notion that kids explore science if given the chance is, sadly, false. It's been debunked so many times it isn't funny, and there's no reasonable doubt. Maybe it's simply the average temperature and the general boringness of the country.

Entire school systems are based on the "creativity" idea. Here's the rub : with the exception of one ... they're all doing horrible (not exactly, they either turn out only truly bad students, or they turn out very few very good students, and a large bunch of very bad students to do with it). Taking the exception and drawing the conclusion you want to draw is blatantly dishonest.

What makes students in Hong Kong so good isn't really the cramming and the long hours. They're part of it, but the main thing is : in Hong Kong, you study well, and you might make it. Don't make it and you end up without protection in poverty and misery. It's the threat, and the credibility of the threat, over a long time that makes the difference. Unlike your "foster kids' creativity" idea, this idea has been shown to work consistently across the globe in many studies. One thing that makes a large difference between kids performance is the rich-poor gap. The bigger the gap, the better the average student. It works better if the best students are pretty much guaranteed good jobs.

Several researchers have been caught outright falsifying results to get the ideologically correct result : that letting kids do whatever they want makes them better students. Sadly, it does not. This idea gets enormous political support, sadly it's false.
