On FlightCar, I would suggest:

First, we have to notice the nature of the customer 'load', e.g., on their shuttle car/bus, front desk, rental operation, etc. That is, this load has peaks and valleys, some fairly predictable based on airline schedules, some based on weather, and some just 'random' things independent of anything in the past available to be used as a predictor.

Second, for such a load, there nevertheless will be a strong effect from the law of large numbers that as the load increases the standard deviation of the load will become a smaller and smaller fraction of the average load. That is, a large load is much more predictable than a small load.

Third, then, for efficiency in staffing, shuttle cars/buses, happy customers, etc. want a large load.

Fourth, notice that the customers who leave their cars are likely residents of the area surrounding the airport. I.e., if Joe lives in Kansas City and flies to Los Angeles, maybe that means he wants to leave his car at the Kansas City location, that is, use the service in Kansas City, but does not much mean he wants to use it in Los Angeles.

Fifth, notice that a location of FlightCar in Kansas City is not in much competition with a competitor in, say, Cleveland. That is, this business is heavily geographically local.

So, net, for a large load, for repeat customers at a location, and to defend against competition at a location, want to concentrate on that location and do well there before moving to another location. So, this business can have a fairly strong geographical barrier to entry. That is, it is basically a local business. So, a 'big national or international rollout' should be delayed in favor of just doing well one city at a time.

Well, maybe "totally" was used in the new (absence of) meaning that is used nowadays to totally look cool, as in "I totally like doughnuts" (here "totally" conveys nothing more than "really", or any other stopwords). In this case, yes, I agree: the Chinese government "somewhat" or "really" controls Chinese internet, and even probably has its hand on a on/off switch somewhere.

But in English and in normal discussions, "totally" means "in totality", or "in the sum and all its parts". Related totalitarism means "control of every part of people's life". We need not to look very far to see an example of a "totally gov-controled internet": North Korea is just like that.

But China is not. The sheer number of posts by minute means it cannot be realistically "totally controlled", because automatic filters are easy to circumvent, and human filters are not fast enough. A simple rumour of ex-ex-president Jiang's death would spread like fire and no deleting can stop it. The only way to stop that would be to shut down internet, and /this/ would push everyone in the streets.

What I mean is that the Chinese Internet is now a heavyweight social force that is already out of Chinese government control (or anyone else, for that matter). They have to live with it, and adapt themselves.
But I can only make A implement B in the file that defines A, at least according to the comments here:

It's a common thing when you're in the military to toss around disparaging comments about the person that recruited you. Personally, everything my recruiter had said was true:

"When they ask you if you want to be a Nuc, say no." -- he could have got a lot of good will at his recruiting office if I chose to be a nuclear tech, but he was absolutely right in telling me this. They never came to ask me, because I had never taken algebra in high school.

"If you have a choice between an east coast and west coast ship, choose west coast." -- Absolutely agree with this. West coast is a much more relaxed attitude compared to east coast, unless you're forward deployed.

"In bootcamp, get the yeoman job." -- I listened to him and was able to get the division yeoman job. This allowed me to travel around base by myself -- something you'd appreciate if you've been through the bootcamp experience. It also led to me getting a meritorious promotion (only 2 or so recruits per division of like 30-50 got this), and getting promoted earlier decreases the amount of time required for you to advance to the next rank.

"Run a lot before you go to bootcamp". Ironically, he was a very slow runner, but I took his advice and worked out nearly daily for the two months before I left. At the time, in order to pass the run test and graduate from bootcamp you were required to run 1.5 miles in 12:15, which would have been nigh impossible for me had I not practiced a bunch beforehand. I eventually got it down to 10:25 in bootcamp, which is a decently admirable run time. Women get approx. an extra minute longer.
For me at least, part of it is getting a fresh start on the idea. Rewriting stuff usually makes it clearer. Temporariness and the unlimited feeling of paper help with freeing up your mind to just let stuff loose.

Among other problems though is that sometimes the stuff you write turns out not to be that temporary, and that's often the times when rewriting it in digital form is useless. I'm trying to figure out how to design a digital tool that's better than paper in these respects.
That's my bad. I should have segmented the list to exclude people who were certified as unaccredited. I forgot to do that in the rush of things. I'm sorry for the tease!
It seems to me that farmers spend a long time agonizing over what to feed their pigs, but don't often get to talk with people who are interested in hearing what they feed their pigs. To have someone to braindump to is a delight.

For programmers, everyone is trying constantly to braindump to everyone else; that's half of what the blog posts on HN consist of. And everyone wants their braindumps analyzed, and, more importantly, debugged. "I'm feeding my pigs horse meat--did I make the right decision?"

When you're exposed to it so often, it's hard not to get tired of telling people about the benefits of grain over horse meat.
I have participated in 11 so far and have 4 just starting or soon to start. I can think of a good number I intend to take. I dropped out of 4 so far. And completed 7. 2 with distinction.

I have only used the coursera platform.

MOOC is definitely disruptive and new societal structures will develop in this space.
I just chose what I liked and had fun with. Hung out with people working on Blender. Hung out in the perl IRC channel on freenode. Hung out with a group doing an Open Source game called Planeshift which wasn't high profile in any way but it gave me experience. And put me in contact with people who had connections.

This is a great option for a lot of people. Glad to see you posted this. Spend 4 years in the military and you leave with great experience, have learned how to "work hard", you're respected by your peers and future employers plus you likely have a bunch of money in savings. Really wonderful option for the right people.
I'd be interested to combine these charts with some other data that might be related, such as doctors' student loan and mortgage debt, per capita income, waiting times for various procedures, and maybe even a measure of how many citizens there are per doctor (as a way of determining relative barriers to entry for medical professionals). I don't really have a good sense about how all of those things stack up in other places, but I suspect the U.S. would be an outlier in some of those as well.
This "strange" deal actually did a few things for Yahoo:
- people are talking about it (and not in a bad way, like it was with the telecommuting memo)
- this may attract some fresh talent (just out of novelty; before, Yahoo was pretty much written off)
- it's crazy enough, it's actually pretty energizing for the right kind of people on the inside

On the other hand, I can only imagine what kind of internal HR issues these acqui-hires may create for Yahoo.
http://instantna.me/ would be a fantastic domain name for this website. And it's not taken!
Interesting, I've got 16GB on my desktop machine (ECC) and it has reported a correctable ECC error about three times in probably 18 months of run time.
Programming is hard, but that's where the fun is. Writing 21 nested callbacks isn't that hard especially with some copy and paste, finding a solution that does not look that ugly is hard, but otherwise programming will be really boring. I mean writing code that merely works is boring most of the time. If finding an elegant solution is not more fun than finding a working solution for you (those who enjoyed math knows what I mean), then programming maybe not your thing.
That is true. Funny you mention Ruby as I have just completed Code School's Try Ruby course this weekend!

However, how could I make any particularly meaningful contribution in a language I am just learning? I feel that any issues or new features in an open source project probably require some fairly advanced knowledge, no?
SmartOS is definitely not intended to be used as a desktop system, but it can work great as a home server if you have some spare hardware.

OpenIndiana is another Illumos distro that can be used as a desktop. You get all of the core benefits of Illumos (zones, zfs, dtrace). The big downside is that you don't get the nice tools for managing zones/vms that SmartOS provides (vmadm/imgadm).

FreeBSD has ported a lot of the best features from Illumos so it could also work for you.

Just remember that an OS is only worth running if it has DTrace.
"More to the point, if you are paying someone six figures to write code, trying to save a few hundred bucks a year by giving them hardware they don't like is just plain stupid."

And if the company is stupid about something as fundamental as creating a productive working environment, you can be sure they'll be stupid about lots of other things as well.
I've been making heavy use of OpenVZ. The documentation isn't the best, but it's often used for VPS slices.
My advice is don't join the military unless you really have no other options. You don't want something that's going to take up years of your life cause you won't have time to hack around.

You can start something up yourself, but just know that it will be a struggle. I started halis.io and every user I get is like a small miracle. It's a tough go at first when nobody knows you.

It's good that you know how to program but I would focus on the most basic, but in demand skills, when marketing yourself. HTML, CSS, Javascript. If you can prove that you know how to do a database, great, but almost any company needs websites.

You probably won't get paid as much just doing sites (at first). But the goal is to build a portfolio that you can show off to get further up the food chain later.

Best of luck to you bud.
Health insurance premiums in America are about to jump even higher because of two key points in Obamacare.

1: By 2014 it will be illegal for an insurance company to deny coverage to a customer with pre-existing conditions. This is great news for people with pre-existing conditions, but bad news for everyone else, who will have to cover the cost through increased premiums.

2: Obamacare carries a clause in which consumers may opt out of government-approved healthcare and pay a tax penalty instead. The CBO estimates that in 2016 the average penalty will be $1200 per year.

In combination these two factors will create massive upward pressure on health insurance premiums.

Healthy consumers who carry mainly catastrophic insurance will choose to drop their coverage en masse in favor of paying the penalty.

After all, if they ever get really sick, they can always sign up for insurance because it's now illegal to deny coverage to someone with pre-existing conditions!

This will drive insurance prices higher, as there will be an ever-shrinking pool of consumers paying premiums.
Wow, the power of charity!

What's wrong with being polite? It doesn't cost any extra and there are a lot of people who appreciate it.
If you are looking at web languages, you can't really go wrong with PHP, Ruby or Python.

There are many tutorials and screencasts of the various frameworks for the different languages.

Main thing is to just try them all out and see which clicks for you.

Enjoy.

Edit: And Javascript!
How does this compare to OpenVZ? I'm assuming this is much lighter than OpenVZ or am I wrong there?

I've always thought the US healthcare system was bad but I never realised how expensive it really was. I pay nothing towards healthcare, I don't pay for prescriptions (those are free for everyone here), and although getting a doctor's appointment can take a week or so at times (unless it's an emergency) I get good service. And none of this is thanks to insurance, benefits provided by my employer or government - it's the same for everyone.
Do they actually change what URL they have stored in their feed database, though? Or do they just follow the redirect each and every time they access the feed? It matters when the old server is eventually taken down. (Keeping in mind that while Cool URLs Don't Change, most servers and domains are managed by Uncool people.)
> Unlike Douban, sensational topics posted on Weibo can sway public opinions and cause social tensions

I agree that a topic must be echoed on Weibo to become "sensational" but many of these topics started in Douban or other less noisy places.

> [Weibo has a] very tight grasp on what can and cannot be posted

There are automated filters, which are easy to circumvent, and human censors, who are not fast enough in many cases. And there is a fluctuent red-line that most influencial posters know and play with. I think the beast is now becoming stronger than its tamer. Which means either it will be shot in the head (shut down), which would trigger a gigantic turnmoil(#), or society and government will adapt to this new social force.

(#) turnmoil is what the government is trying to avoid, so turning off Weibo would be a medication worse than the illness.

It's very important that everything medical before and during your career is documented. First off, a lot of the physical and mental stress down the road can exacerbate previous conditions and lead to more major problems. Secondly, everything that occurs and is documented in your military health record can be treated for free by any VA medical facility for the rest of your life, even if you don't have health insurance.

That being said, certain common diagnoses will preclude you from entering service: ADD/ADHD, bi-polar disorder, bad knees, fibromyalgia, among other things. Obesity is kind of a no-brainer thing -- there's a maximum body fat percentage and height/weight ratio.

If it's in your health record right now, then it should definitely be declared, in my opinion. You'd only be doing yourself a disservice later on by not doing so.
I was hoping for a slightly higher-level look at what problems not to solve. It seems that Collections.me solves a solved problem - convenient online storage. It iterates a bit on it, but you seem to be building something that is largely a pile of already-solved problems, both in its implementation and use cases. Just my opinion, of course, and that is how many services advance, but I thought I'd voice it in light of the purpose of your post.
Huh- that seems weird to me too - my experience is that programmers generally love to share their knowledge and talk about their field. My tendency when newbies ask me about programming is to share as much info as possible, possibly too much - but then, I've been known to bust out my laptop at fancy dinner parties and start demoing how to write HTML.
There are a number of differences between the US and all the other countries which may explain the costs. For example - Malpractice insurance costs in the US are much higher, the salaries for doctors are higher, the cost of their education is higher, living expenses can be higher...

And because it is privatized - in the UK for example, the government can negotiate fees to bring down costs (for drugs, services etc). They can set prescribing guidelines so physicians don't just prescribe what they want and they can set treatment protocols and budgets so the physicians don't order unnecessary scans. All this brings down the overall costs.
typically i've noticed YouTube popularity either involves juvenile humor, or cleavage.
I could see how that's the case. If you're referring to what I said, you'll note that I said nothing about my own recruiter other than that he lied to my parents to increase the chances of them agreeing to let me go, because I was a minor. Which he admitted to doing.
Because everyone in all industries pays list price. Right.
Open source android BT software
FrostWire for Android will let you search and download files from the BitTorrent network and it will let you share files with other FrostWire for Android devices on the same local network (via WiFi)

The local sharing happens through a simple JSON/HTTP protocol (still to be documented, you can look at how it works on the code for now, very very simple)

We'll put the specs of this protocol out for you to implement clients in your favorite platform, this way you will be able to browse, stream media or download files that FrostWire for Android users have decided to share on the local network.

FrostWire for Android also features a simple media player that we'll be evolving with future releases.

Hi Michelle!

That's not too hard to explain. Some programmers see themselves as part of a clique. Their code and ways are what keeps them superior, experts in the field that they work in. The sunscreen that coats their javascript perhaps took them a hard couple hours of debugging to discover, and many programmers are the type of people who feel and rationalize "If it took me this long, this newb should go through the same process".

Of course, there are many exceptions- all the online communities, forums, etc. But there's always some part that does work as I described. Hell, even I get annoyed sometimes and tell someone who's starting out "go google why you don't want a GOTO statement in code"...

You can always get a job working in an Alaskan cannery. Most coastal towns will have one. It is not crap work -- it's fish guts work. They will probably pay minimum wage, which is $7.25 an hour at the moment, but generally you can work as much OT as you like. Many canneries will pay your way from Seattle, and give you room and board as well -- for certain values of "room" and "board".

If you're lucky and social, you can find your way onto a fishing boat; deckhands will usually get a percentage of the catch ($$$), and the work is easier.

I've been through Yakima a time or two before. A gritty wind blew continually -- it seemed like the kind of place where not even the dust wanted to settle. My sympathies to the poster.
We all have written code only to come back to it a few weeks later and think "oh god, what in the world was I thinking". If only code refactored itself over the time; small projects aren't an issue, but there's a point in every devs life when you have this monstrous one-eyed, ten thousand lined class that works fine in production but no one knows how or why it works and the idea of making a single change to it gives you pure panic and terror. And you know you have to rewrite it, but you have a hard time justifying spending two weeks on getting nothing tangible done, so to speak. The class goes on unfactored for a while (until it inevitably breaks) but at least you come to this almost zen realization that beautiful code = simple, short, and self descriptive code.
Cool, where are you getting the data from?
Umm is it just me or does it not look ludicrous but just higher if you compare the AVERAGES to the other countries' AVERGAGES, rathr than out 95th Percentile to other countries' AVERGAES?
>For HD quality live streaming with P2P, users need to donate also bandwidth when not watching.

How is that compatible with being live? To supply bandwidth for a live stream you would have to be downloading it simultaneously with uploading it, so if that node is not watching the video then it would be more efficient to have the node it's receiving from and sending to just connect directly.

I suppose if some subset of nodes can upload at a rate faster than the bitrate then you can gain some efficiency by consuming all of their available bandwidth, but unless those nodes have several times more upload bandwidth than the stream bitrate, that would tend to be pretty inefficient.

It seems like the better solution is just to increase the upload capacity for the average peer -- either through political pressure on the telcos to expand capacity, or through market pressure by just enforcing T4T and then offering both high and low quality streams but only offering high quality streams to the users with sufficient upload capacity to keep up with them, which would spur those who can to subscribe to a more expensive internet package with greater upload capacity.

>Unfortunately, going beyond T4T is an open scientific problem.

It seems like something bitcoin-like could work pretty well: Make it so that to get a download credit you either do some serious computation that requires a nontrivial amount of computing resources, or you upload to someone who has credits, and then they lose them and you get them. Which is basically T4T with accounting, except that it scales better because you can adapt to shortages and surpluses of credits by adjusting the amount of computing resources necessary to generate new credits.

It also solves the T4T bootstrap problem. Peers that newly join the network, or who had credits but spent them on something nobody else wants and so can't earn any upload credits because there is no one to download what they have, can crunch for credits instead of uploading and get back into the network.

Any reason you can think of why that wouldn't work?
That's amazing! We should've been friends.
Why are my points negative for my comment? Is it not true that he made a statement about FOX as though it were known accepted truth and did not back it up with a factual reference?
Many states in the US have strict laws against "unlicensed practice of law" -- which includes giving advice.

This is why many American commenters feel the need to add an "I Am Not A Lawyer" disclaimer when commenting on any legal issues.

I doubt if the IANAL acronym would be enough, though. Either spell it out, or leave it out.
