The largest factor for Airline profitability, at least historically, is the cost of fuel. Airlines that sign a 1/2/5/10 year futures agreement at exactly the right moment can save an extraordinary amount of money compared to their competition.

Jet Blue, for example, has been doing quite well in the last few years. The biggest reason for this isn't their (quite wonderful) service or (relatively new) air fleet; it's because their fuel contracts were signed at a damn near perfect moment.

Airlines run razor thin margins. A few percent savings in fuel can easily double their margin, which can be then spent on marketing, fleet improvements, sniping experienced pilots by offering higher wages, or any other form of capital investment.
I'm with Sprint and they offer unlimited data for iPhone users and probably across their network for smartphone users.

My usage is higher then average but even using Spotify and Pandora in the car everyday (30 to 40 mile drives) I rarely go over 2 gigabytes.
That's ... not open source. I think information wants to be free, too, but this is unethical and is not what open source is about. You can't share somebody else's knowledge - just your own.

On my Android phone I use the doggcatcher app to download podcasts. I go well over 3gb each month, but as a Sprint customer I currently do not need to worry about the limits.

I could certainly set the app to only download on wifi and avoid the issue entirely. However, it is quite nice to have it check hourly for new podcasts and download them at that point no matter where I am.
Turmoil Breeds Opportunity: Greece Entrepreneur Week
something about this screams "bailout"
Very nice snippets, though they're meant to work only with Django's default class views.

A few months ago I started using a small class-based views library called aino-utkik[1] and haven't looked back.

Instead of this:

class ArtistLogin(FormView):
form_class = ArtistLoginForm
template_name = 'artists/artist_login.html'

def get(self, request, *args, **kwargs):
request.session.set_test_cookie()
return super(ArtistLogin, self).get(request, *args, **kwargs)

def form_valid(self, form):
login(self.request, form.artist)
return HttpResponseRedirect(reverse('artist_mypage'))

def get_form_kwargs(self):
kwargs = super(ArtistLogin, self).get_form_kwargs()
kwargs['request'] = self.request
return kwargs

I can write this:

class ArtistLogin(View):
def setup(self):
self.c.form = ArtistLoginForm(
request=self.request, data=self.request.POST or None)

def get(self):
self.request.session.set_test_cookie()

def post(self):
if self.c.form.is_valid():
login(self.request, self.c.form.artist)
return HttpResponseRedirect(reverse('artist_mypage'))

which I find way more elegant.

Yes, but from when IE4 came out (1997) until late 2004 when Firefox came out, IE was the undisputed best browser (yes I'm ignoring Opera as we always have). That was 7 very long years of getting people to upgrade to IE from NN4.
That's not entirely true for T-Mobile, actually. You still connect to 3G towers even after throttling, but you are slowed down to "2G" speeds. In practice, the 2G speeds are much slower than EDGE, but slightly faster than GPRS.
Just because other people have been jackasses does not give you an excuse to be a jackass. I've seen plenty of divorces that ended quite happily because both people were civil to each other. You just don't hear about those because they don't usually make much noise.

But even if you believe that it does justify it, however misguided that is, since when does a divorce ever justify screwing over your children in addition to your spouse? At that point, it's just pure greed.
Tweetlibs - A Twitter Madlibs Engine (Super Alpha)
There are things in life that one doesn't has to try in order to know that they are bad.
If you don't want to be considered a troll, then don't make these pithy comments.

1) The parent post did not use the word 'steal.'

2) The people that get up in arms about usage of 'steal' vs. 'copyright infringement' are making a semantic argument that is not really hard to understand. Whether you think that the semantic argument has merit or not is beside the point.

Your post makes it seem like you either do not understand the semantic argument (which I personally find unlikely, but I'll give the benefit of the doubt) or you are purposely acting like you don't understand it.
Yes, that's one of the oldest and most useless proposals that gets brought up by at least 5 people in every single discussion of email spam...
This is disappointing. Twitter is great because it is so simple; they should pick the simplest behavior for any user action and stick with it so users can be fully aware of what every action does.
In my view a consultant is different from a freelancer.

Freelancers (and contractors) generally are taken on to do a specific job, they do it, and then they leave. Consultants on the other hand come in to advise, and when they have finished advising they leave some form of documentation or knowledge transfer of their advice for the client to follow afterwards. This is really down to personal understanding of the words however and may vary between industries. I don't think it matters too much, just call yourself whatever you feel most appropriate.

In terms of taxes on the other hand you absolutely should get an accountant and make sure you get it right. There is a big difference between running your own LLC, being "self employed", and being a "sole trader", and the tax requirements are totally different for each (and will vary by country).

As you've used the term 'LLC' I'm assuming your are US based so I can't offer you any specific advice other than get a professional to help you. You should be able to find lots of small business friendly accountants online who's fees are low enough that they will save you significantly more than their fee by making sure you do things correctly.

First, let me thank you for providing a welcome alternative to those of us who were turned off by the "improvements" to Google reader. You made migrating dead-simple and that was a big factor in my choosing NewsBlur over other RSS sites.

My question, though, is that RSS usage seems to have plateaued, and may even be declining. Twitter, especially, has taken a fairly hard line in treating RSS as a second class citizen. Do you think there's a risk that other sites will move away from RSS in favor of social media, and, if so, do you have any plans to deal with that eventuality?
I can't believe no one is talking about how this is all arbitrary and all made up, and a part of an ongoing fleecing of the public resources, the airwaves, like they fleeced us on the right-away we gave them, the telephone lines, which resulted in the whole dark fiber hooked up to nothing.
That is a really nice syntax. I kind of like the specificity of ``form_valid`` (for example), though.

And, yes, our mixins are Django-only (hence the title!)

Also, why the ``set_test_cookie`` on every GET?

Ah I see, that's funny. Whats interesting is that I personally know the guy who made that, and worked next to him at Dreamit Ventures years ago (Dreamit's first class) during a whole summer. So you can imagine my surprise to find the link on your site. For the record, very nice guy.

I agree completely though, 'social' was all the rage. Much like 'Big Data' today.
They should hire him.

To see a post like this is both satisfying and depressing.

Satisfying because it's always good to see someone learn an important life lesson.

Depressing because I know far too many smart people with zero humility. It's such. a. shame.
Right - and each new product increases the scope of the profiling they are able to do and reveals more about their product strategy. At a certain point this became more than I was willing to tolerate in return for the value of the products.

French startup, founded&located in Bolivia, la Paz!

we mainly do webdev (jQuery frameworks, Php, sql&mongodb-though not much yet -_-, ... open to everything exciting!apart porn) for a tourism software project, actually used by 10 clients.

Quick expansion the following months. The team is leaded by a french engineer who did succeed in tourism and now started 1y ago his own application for this industry.

languages:
English: mandatory;
Spanish: you'll learn it here, don't worry;
French: then, we will have to love you.

Any position welcome, though no intern. Not for discrimination or anything, this is just cause costs of bringing people from outside the country are expensive.We'd love to hear from people interested in staying in a foreign country for a year or 2.Gain experience, have freedom!
Wire-based services suffer from contention as well, just at a much higher usage than wireless services.

A provider's costs to serve you are largely fixed. A sane bill will have a large fixed cost plus a variable cost for usage. For example, rather than the fixed ~$45/month I pay to Comcast, I'd expect to pay something like $30/month for the connection itself, then another $15 (or perhaps more, since I'm probably a heavier user than the average) for bandwidth.

We manage to get by without fixed bills for gasoline, food, electricity, water, etc., what makes internet special where you absolutely need it to be consistent?
Vista added a bunch of areas that prompt for admin for no reason, and to get in as a limited user is definitely more painful.

Note that there is no security need for admin here, just a dumb prompt that you can't second-guess.
AT&T Revises Throttling Policy to Begin at 3GB
I'm not saying they did it alone, or quickly, but at some point you become good enough at reading WoW logs that you realize you can build programs that could interpret them for you and do a lot of the difficult work of finding out what happened to items the player started with (and which items were actually gained during the hack, as when a character is used for farming until locked out) and so you write a simple script. You show your manager, it gets approved, and now all top tier support staff is able to be more efficient at the job that takes them the most time. Iterate through this process with different GMs writing different tools, some help from the WoW dev team and other teams so that different log files are created which are easier to interpret. I can't give specific inside information, but I'll say it used to take hours to restore a hacked account but last week my wife's account was somehow compromised (we think when we used an Internet cafe to play, or possibly due to a shared password—either way, it took a former account investigator seeing his wife hacked before finally adding Phone Secure to protect himself) and she had an in-game mail with her lost stuff within an hour of reporting the hack.

So yes, the tool building was voluntary (eventually sanctioned and encouraged, even of it was unofficial at first) and that directly led to an increase in productivity (supply) which has come to a head with demand decreasing simultaneously (referring both to drops in subscription levels and, more importantly, even the long tail of WoW players being incentivized and easily able to add forms of multi-factor authentication to protect their accounts and prevent the compromises in the first place). It would be cynical to see any of these advancements (except the lower subscription numbers, of course) as bad things, but also naïve to ignore that they're a large reason why the department finds themselves in a position where they're starving for work (mostly a guess on my part, based on response times to in-game support requests, coupled with interpretations of the layoff and Blizzard's official statement about it, as well as knowledge of who I knew that was affected and who I knew that wasn't).

i'm actually happy about this. i hate when my twitter stream gets flooded with people who use ".@" when replying to someone else. no offense to those people, but i generally don't care about your out of context reply that much.
My billing cycle ends tomorrow and I'm at 5935.74 MB. For me it's streaming podcasts (managing downloads in iTunes is a pain), YouTube, and lots of web browsing. During the MLB season I probably use even more, because I stream multiple games per day (I haven't checked this). I also semi-frequently buy albums from iTunes on the phone.

In short, it's not very hard if you use the phone like I do.

Edit: Wow, it actually appears I was hovering around 1GB per month until last September, during which I used 2.7GB -- a jump from 0.5 GB the month before -- and after which it's been a close-to-linear increase. Weird. I didn't realize my habits have so drastically changed.
Hi, CloudMine founder here.

The idea is that you can now have 3rd party services interact with your CloudMine powered app from the server side. From there, you can update data/state, send push notifications, or do whatever makes sense for your app.

That particular example is for a contest we are running with Nexmo http://blog.nexmo.com/post/18010293444/contest-cloudmine-nex....

I don't see NewsBlur as competing with other RSS feed readers, many of which are seeing declining use and are either folding or are in the process of folding. NewsBlur, on the other hand, is doing very well because I'm charging people and can afford the popular opinion of "declining popularity" so long as it means revenue keeps increasing.

You have to remember that NewsBlur is unlike any other reader. It shows the original site, it filters and highlights stories, and it's being actively developed. There is a huge swatch of sites for which using Twitter is no substitute. You just want to read every post from those Tumblrs. You don't want to miss what Gruber is saying on Daring Fireball. And Salt & Fat podcasts are only once a week. You sure you want to rely on catching that single tweet a week that gives the link?

As long as the technology is good, I think there's an enormous market, full of people struggling to keep up with a dozen blogs by having to manually visit them all every day.

I'm not going for the expert RSS readers who use RSS in a way I never did. I followed 40-some sites when I started building NewsBlur. I now follow around 110. I never used Google Reader, and I think there's a lot more people like me than the ones who were already hooked on RSS.
When humans offload most of who we are onto handheld devices, the fifth amendment will not be necessary, just take the phone and query it for thought histories of the guilty, er, suspect.

Torturing a suspect for self incriminating details: not ok. Breaking encryption on a phone, bypassing security password lockouts and accessing memory history: ok!
It'd be great if .@ would still count as a reply (i.e. that tweet would still contain a pointer to the tweet it's replying to) but be visible by everyone. It's the best of both worlds.

Also I wonder what happens if you hit Reply, but then delete or modify the @username. Is it still counted as a reply to that person's tweet, and therefore only visible to the intersection of your followers?

Yammer is hiring engineers in SF and London, and a bunch of other non-engineering positions in London/NYC/AUS/elsewhere. Full jobs listing at https://www.yammer.com/jobs

Yammer is basically a social network for the enterprise, but Yammer isn't just where you talk about work, it's increasingly where you do work.

Large corporations are really inefficient and hierarchical and Dilbert-y, and we build software that treats every employee as an empowered human being. We have a success-story video on our site from Supervalu, a large retail store chain in the US, and their CTO tells a story about how Yammer literally changed the way they do business. In the old world, store managers would report their intelligence up the managerial chain, the upper management would try to synthesize everything, and 3 months later a "report" would be issued that told everyone how to best try to do their jobs. After Yammer, store managers would just talk to each other over Yammer, learn directly what was successful and what wasn't, and as a side effect, let the upper management gain invaluable visibility into day-to-day operations. When we say Yammer "breaks down silos" and "enables horizontal communication", this is what we mean. Sure, Yammer is just like Facebook, but we're so much more than that. Corporations don't share cat pictures, they turn into efficient business machines.

Supervalu testimonial video: https://www.yammer.com/customers
In fact, Supervalu isn't the only company that has changed the way they work due to Yammer. We have tons of examples at that link. Yammer is used by 85% of the Fortune 500.

Yammer is expanding. We just raised an 85MM round, reflecting a valuation that puts on right up there in the enterprise software space. We're growing quickly and we need strong capable solid engineers to help us. We have an excellent technical platform but we need to scale more. This is where you come in. We're looking for engineers of all stripes, be it Ruby/Rails, JS/Node, Java/Scala, Obj-C/iOS/Android, or other. Again, full list at https://www.yammer.com/jobs

If you're remotely interested in solving real engineering problems at scale, for a serious application, I urge you to get in touch. My email is bkudria@yammer-inc.com, and you can ask me any questions about Yammer that you'd like.
Not only is Samuel an amazing developer, but he is also the perfect person to build the news reader of the future. Check out his Github repo for some of the cleanest Python / JS code you'll ever come across. https://github.com/samuelclay/NewsBlur

I worked on a personalized news reader in 2009 (http://www.readwriteweb.com/start/2009/11/parsely-a-feed-rea...). We decided ultimately to abandon the project to pursue Parse.ly Dash, a media analytics tool. When we were winding down Parse.ly Reader, I discovered Newsblur. I can say confidently that NewsBlur gets everything "right" that we got "wrong" in our original design. I now use NewsBlur as my primary reader and I am a paying customer. I have also evangelized it to my friends. I am really excited that Samuel is going to go full-time on this project and make it one of the best pieces of software on the web for news junkies like me.

I apologize if this is off topic, but from the other comments it seems that everyone here was aware of this .@ command (something I'd never heard of before). Is there some kind of list where all these special commands may be found?
I get that, but what if there's a discussion you would care about, but they used .@ so you can't follow the thread without scanning and trying to match up timestamps? I'd rather err on the side of allowing tweeters to do something potentially annoying than preventing them from doing something useful.

Nearly every XS library takes input with utf-8 encoded to bytes, so you have to manually juggle the encoding when using it. There is no documentation stating what encoding any library expects. I just checked a source tree and found 41 calls to encode_utf8 and 42 calls to decode_utf8 to deal with this across dozens of libraries.

I think that hitting "reply" should still contain a pointer even if you don't include the @username. Doesn't the threaded-reply already imply that you're addressing that person?
Interesting, but the article completely washes over the fact that while a polynomial algorithm exists for an NP algorithm, if P = NP, it has not yet been determined; so, while prime factorization would be P in P = NP, we would have to discover that particular P = NP algorithm. Technically, I suppose we could map prime factorization to 3-SAT and use the O(n^$some_ridiculous_number) algorithm to get prime factors, but in a strong majority of cases, it would probably still be more efficient to use the a^N algorithm.
