One thing I've never bothered to do is learn an API of X language really well. Because, I thought, I'll just look up whatever I don't know. But I'm constantly stopping to look things up and it really slows me down. Now I'm beginning to think there's really some value in having a strong command of an API. Has anyone tried using an SRS tool to help with this? Or is it simply a matter of not having enough experience with X language?
True, but a more accurate description of what you meant is "if you believe in evolution by natural selection, you'd have to put it the other way around."
I'd love to hear about it as soon as possible (i.e., early enough in the semester for me to act on it).

I'm already updating webassign to follow your suggestion, current material + old stuff each week. Anything else you did (beyond SRS) would also be useful to know.
I've toyed with the idea of keeping a practice journal, but I've always been too lazy to stick to it. Your comment has inspired me though! This way, I can go back X number of days and review whatever I was working on then.

I wouldn't get hung up on the cloning part. If your goal is to create a simpler version of a project management suite, then do that. Find out what features you want in it and build it. If it turns out cheaper than basecamp with fewer features, or more expensive with more features, then market it accordingly.

It could be, but that is not the whole story. Plenty of countries were 'late' in wising up to this and took a lot longer to adapt to out of band signalling.

So, depending on the age of the network you're on there is some chance that even today you could use tricks like these.

1993 is perfectly believable to me, depending on the location of the person making the claim.

The tone to reset a trunk was 2.6 KHz, the reason why '2600' is still a term with notstalgia attached to it for very early hackers.
That's what makes this work, though --- you only need one result, one name and the associated 'tagged' names. Then you search each of the tagged names.

60 resuls is plenty to get one good result per name --- heck, you don't even need that one. Even just one good result per ply will get reasonable results.
I applaud the transparency of EY here. This is far more honesty than you get from most hosting companies.

I'm also pleased that github is upgrading since I've noticed gradually decreasing performance for about a year now which prompted me to setup my own private repo server (but I missed the github front-end). Kudos to github for doing something about it.
I think that's great. I sometimes read crap though. I get sucked in by those OMG THE WORLD IS ENDING AND YOU NEED TO READ THIS TO LIVE type headlines... even though I know better I still click on it.

You're a more disciplined man than I, and it's good to know some people are making the effort to keep them honest.
Up to around 500 or so while maintaining a decent framerate (say, better than 30FPS in steady state).

I was using Java's Processing though - which I would expect to be considerably faster than Processing.js. I didn't try decoupling the UI from the computation/model (since the performance was already more than sufficient for my needs), but my gut tells me that my physics code was the bottleneck - not Processing itself.
Hmm... Did you consider the one featured rather prominently in a box under the heading "The third (and golden) basic law"?

Great article. Aren't there surgically embedded gps chips for tracking children?

Agreed. That does seem more efficient... when can we launch?
There is a fundamental flaw in that theory, and it is based in the assumption that travelling at the speed of light affects time, which it doesn't. It only APPEARS TO THE RELATIVE OBSERVER. If you travel at SOL for one minute from earth to andromeda and back, time on earth will have ellapsed one minute too. It is extremely retarded to think otherwise and we should blame einstein for that.

Relativism is about relative perception between observers, not about absolute reality of facts. We measure facts with light so they APPEAR different when in reality they aren't.

If you leave earth at SOL, our perception from earth of your time will change the farther you move, but when you return the inverse perception applies so time adjusts itself and you just travelled ONE MINUTE, not a hundred years.

So yes, the whole interstellar trade theory is bogus, but a nice fiction tale nonetheless.

Could you point us at the sources you used to develop the method? You mention the concepts have been around for a long time.

Ah, good point! You'd have to keep quite a few digests of the 'state' to figure out that you're caught in a loop, the 'halting problem' in disguise.

You could work out the size of the cycle by checking the lower and upper limit of the populations though, if the lower and upper limits have not changed for a number of cycles it could also be end-of-game.
Japanese parents will happily let six year olds navigate to their school across town. Middle schoolers and high schoolers routinely go to schools in other cities, via trains.

Nobody believes me when I say middle class Americans would call that child abuse.
This definitely resonates with me. I got my first paying Java gig in 1996 (really). Back then, one person could be reasonably expected to know all of Java, and work on any project that was feasible to do in Java, whether that was applets, servers, fancy graphics, database access (no JDBC back then!), anything.

Fast forward a few years, I knew JDBC and Swing pretty well, a little of the EJB stuff, there were whole vast swathes of the Java universe that were simply out of scope. I got out of Java a few years ago, but I imagine it must be even more so now. With my current main languages, Python and OCaml, I still feel as if I've barely scratched the surface (and in the company I count as an "expert").

But this isn't limited to languages, back then a DBA could know all of Oracle 7.3.4, now Oracle 11g is too big for any one person to know it all. There's no such thing as a generalist DBA anymore. You know enough to operate anything your organization uses day to day or fix it if it breaks in the middle of the night, but a tricky problem outside your specialist area will need to wait 'til whoever in the company specializes in that can take a look the next day.
Sometimes I think you US citizen's are out of your minds. Why is it so hard to be a community and trust each other? Is it about the mainstream media, Hollywood, or something else that makes you feel so unsecured?
A child walking to school just a few blocks is a question? In my child hood I walked to school more than fifteen minutes with all my friends. Also I would go out after school and would not come home untill it was dark (also same for all my friends).

I'm not sure about nowadays parent for my country. But I believe they are not that unsecured yet. And let their children walk or travel by themselves whenever it is possible.

Is there market demand (ie some genuine unmet need)? If so, then put up some content and people will eventually come. It may be slow, depending in part on how much content you put up. I know of a site that started as a list of links and grew into a forum. The forum part took over and the resource part is now kind of underserved. I think the forum was better when the resource part was more important to the owner. I also know of forums that spring up spontaneously around good websites because folks want to talk and want to connect. People need a reason to be there to begin with.
iTunes hasn't hit a sales wall because digital music is a lot more convenient that anything that's come before it, and iTunes made digital music dead simple. Having your entire music collection in your pocket makes storing it any other way seem like a step backwards. That convenience trumps any tech worries most people have.
"Children are driven to schools two blocks away. At some schools, parents drive up with their children’s names displayed on their dashboards, a school official radios to the building, and each child is escorted out."

Plus calling the cops because they saw a young kid walking alone? What the hell is wrong with these people?

I think this whole fear is a simple case of the media over-reporting child abductions. I'm curious as to the numbers of abductions over the past 30 years. Article states only a couple hundred / year in present day.

When we moved to Canada I walked to school alone all the time when I was in Grade 2 and up. My mom was in English classes or at a job so we could survive. I don't see an issue with it to this day and I believe it made me a more independent person in the long run (I'm 24 so I wasn't a child that long ago)

Taking the time to learn things in-depth is what grad school is for.
A program to track your hours, something to make a contact database and a todo list. All of those are pretty essential.

Billing and such you can do with any word processor.

If you go this route make sure that you reserve enough for taxes once the money starts coming in. Plenty of people fall into that trap. A good rule of thumb is to take the 'gross' tax rate and reserve that much right away whenever a bill gets paid on a savings account.

Then when tax time comes around you have your deductibles and you end up with some money left over instead of a hole to fill.
I think Japanese intonation is very hard for native english speakers but it's not hard at all for someone speaking romance languages (the sonorities are rather similar to spanish I find...)
How would you feel when you found out your parents have been tracking your every move since you were 6?
I think the article was talking about suburbia. In a mega metropolitan city it's hard to be a community. I've never seen an US city but I believe in these big ones schools and children are located in distant places generally. So walking children must be mostly out of question there.

After a brief look at pubmed I was able to some good supporting evidence, showing significant, moderate (~1.0 cohen effect size) differences between groups using SRS vs other learning techniques.

Is anyone who is more familiar with the research able to provide a summary - it's not my field, but I am very interested. Also, why isn't this method used in schools for homework etc - it would seem a much better if it's been proven.

Fair enough. If the comment was, I'm going to blame my reaction on it being morning. Still going through my coffee so not quite stable yet :) Sorry!
I am not sure about SRS for learning API of a language. However I have recently started to use mind maps for that. Whenever I come across a new language or library I take an A4 and a pen and put down all basic concepts. It helps to grasp the big picture of the system and to see the interconnections of different blocks of code. I prefer mind maps to the standard linear up-down way of writing stuff down because the schematic representation utilized in mind mapping eases the twist between the way information is stored on paper and (presumably) in the human memory.

All in all I find spending some time on studying docs useful in contrast to the pure work-by-doing approach.
Last spring, her son, 10, announced he wanted to walk to soccer practice rather than be driven, a distance of about a mile. Several people who saw the boy walking alone called 911. A police officer stopped him, drove him the rest of the way and then reprimanded Mrs. Pierce.

To me, this is just insane. Walking a mile alone when you're ten years old shouldn't be an issue unless there's a riot going on or something.

What are you telling the kids about the world around them when you're terrified of letting them out into it? Not that people in general are decent people who can be trusted to not cause them any trouble, at least. Maybe this is connected to how "many" Americans feel they need guns to protect themselves?
"About 115 children are kidnapped by strangers each year, according to federal statistics; 250,000 are injured in auto accidents."

The single most effective sentence in the entire story; in fact, it could probably stand for the entire story.
Computer viruses: a cautionary tale
They often encounter disapproval by other parents, scoldings by school administrators, even visits from local constabularies.

To whom they must say, "Mind your own business," "Do your own job," and "Unless you're here to arrest me for committing a crime, get out of my house."

At what point do you stop caring what the neighbors think and start living your own life?
Most telling statistic from the article:

"About 115 children are kidnapped by strangers each year, according to federal statistics; 250,000 are injured in auto accidents."

Most parents have no time to read well researched articles/books on raising children. Their lives are (generally) very hectic and what they learn usually comes from sensationalist media stories and from other parents sharing horror stories they read about.
The opposite is true: kids in big cities live near their school, generally, while suburban kids - owing to sprawl, are more spread out.

My product will definitely not be a 100% copy of basecamp. Basically I shall take their features and philosophy and built it in my own way. And to keep things simple at my end there will no Ajax. This will alone make my product substantially different from the 37s. So I don't think it is some sort of rip off.

I think I shall be serving just couple of hundred customers at maximum; something which will hardly make any difference to 37s bottom line with 3 million customers.

My question as in my original post are:

1. Is it legal? If not, I am not going forward.

2. Is it possible that 37s gets offended? (esp. when I offer comparison with their products)
In my old school system it was against the rules to walk until high school. I vividly remember that they knew someone was riding their bike to school but couldn't figure out who so they confiscated the bike to see who came for it. My wife was waiting at her nephews bus stop to pick him up in the rain just yesterday (first week of school) the bus driver says I don't recognize you and has to call the school to see if she is on the list (she is) 30 minutes later they let her take her nephew and say "Can't be too careful!". It is mind boggling
I think the Pedibus (or walking bus, http://en.wikipedia.org/wiki/Walking_bus ) is a good idea for having children walk to school.

It's a group of children walking to school accompanied by two adults along predefined routes. There are bus stops where children wait for the Pedibus to arrive and then they walk along with the group.
Surgical Robots Operate With Precision
Nice article. As someone who has been involved with open source for a while, I think one of the most annoying things is indeed when people don't even tell you about their problems. I'm already doing work for you for free; I don't have money to go do market research, so I'm counting on you to step up and say something if there's a problem.
Glad you kicked this off.

OP is an expert, he just doesn't realize it.

If you define "expert" as someone who has memorized all possible syntax, then the only experts would be autistic and would need help getting dressed.

OTOH, if an expert is someone who knows how to find the right tool to get the right job done, then OP is clearly already there. As are many of us too, I suppose.

That's the difference between theory and practice.

"If you made this story into a blog post, people would listen."

That's what I hate about people. What makes people pay attention isn't the ideas themselves, but whether it looks like you worked hard in writing it. I've made comments on HN that no one paid any attention to, and then turned them into blog posts and had them get to the top of Reddit or Digg or whatever. Exact same ideas, all I did was visually change the text to make it look more professionally laid out, and carefully rework some of the phrasing to make it sound better to the ear. (Plus add a couple really good first sentences and a good headline.)

I've found that if you actually leave a couple minor mistakes in your blog post it gets more votes, because it look like you're thinking at the edge of your intellectual ability, and people like that. It's the exact same thing Seth said in his post about the Chris Bliss Diss video:

http://sethgodin.typepad.com/seths_blog/2006/03/its_how_you_...

"Today, I got a video, featuring Jason, who just might be the best juggler I have ever seen. Same music, similar routine. Except... five balls. Not three, five. Infinitely more difficult. And Jason makes it look easy.

The thing is, even though I know how much more difficult Jason's routine is and how skilled he is, the very ease of his delivery makes it less likely an audience would give him that same ovation. Interesting how important effort seems to be."
I think this makes some good points about how projects have trouble reaching users. The fact that people try a program 4 years ago and don't check back since, is particularly true.

But I'd add one other big problem for open source: "anti-marketing", in the form of aggregating trolls.

I don't have to Google far to find sites that apparently just crawl SourceForge and dig up whatever crap they can automatically generate ad-ridden pages for. A lot of direct harm to projects comes from trolls:

- They don't properly credit, and certainly don't link to, the page that they crawled (e.g. SourceForge). So users have no way of knowing that a more complete and authoritative source exists.

- They often don't "re-crawl", so within a matter of months they're advertising something extremely old.

- They usually don't have all the details quite right. So their pages seem "authentic", yet are wrong in critical places (such as, system requirements; I've seen things as stupid as non-Windows programs that "require Windows XP").

- Their robots are sloppy. For instance, I've seen them create a "what's new" page that completely misinterprets the original source release notes, resulting in a couple of nonsensical bullet points. This makes it seem like the software maintainer is retarded.

- They give no direct control to project owners. Not only is there no way to update a page, but even if there were, the site has no way of knowing that the person contacting them is the true maintainer of the software.

Whichever one of these trolls becomes king of Google will do the most damage.
