The traffic from HN has reduced my previous statistics to noise, so I've thought I'd as well implement some of the feedback I've got, online now. Also, the server is suffering and I cannot try to set load balancing because I need to run to a meeting (why didn't I before?). So I've added feedback to let you know at which steps the server is struggling, asking for some patience.

Thanks everybody!

It serves 3 purposes:

- forces me to dress / shower / maintain a modicum of hygiene

- gets the heart pumping (at high speeds :)

- with the top down (or all windows open) at higher speeds you feel quite a bit cooler than if you stood in the outside air (in the summer). And in the winter, car blows warm air across the neck, so your head doesn't freeze

All laws in brazil are well thought and mostly free of influence.

The problem lies in the executive.

Basically, there's no enforcement of most laws and others are interpreted as they want.

Maybe it is because I have been stuck working with .NET environments so much, but they seem to be focusing on stuff that is too complicated.

The basic FizzBuzz test is about the right level of complexity. It weeds out those people who cannot even do as simple loop while still giving real coders enough rope to work with to show their stuff.

To be honest, the more advanced concepts in programming can be mentored and corrected if the basics are in place. In my experience, once they pass a basic coding test, you are interviewing for culture, to determine if they are a junior or senior coder, and whether or not they know they are a junior coder and will therefore be open to improving.
I'm sure you can easily identify which set is which using statistical methods. It's probably as simple as finding out which type of distribution each set resembles. Then again, my undergrad statistics is very rusty.
Nice app! Computing the histogram hung on the Apple stock data for me.
If something's the default it tends to get more focus and polish.

I probably could've done it that way, but at the time of the move Gnome 3 wasn't in the repos, nor was GTK3 and I don't see the point in swimming against the flow.

It's always fascinating to me when the population knows that certain events don't affect their line of business, but they let it influence them anyway. It happens so much, not just in private equity, but in corporate finance too.
Well, if somebody walked out on me I guess that would end the interview. :) I have candidates write code on a white board, but not terribly difficult problems, and I always issue this disclaimer:

"My brain doesn't work as well when writing by hand as when I'm typing. This doesn't have to be perfect. If you get stuck, ask for help, we'll talk through it. Think of this as a starting point for a technical conversation."

As a candidate, I would worry about my future coworkers if I were not asked to write code during the interview.
I like the idea. I am trying to buy a chart for my wedding date in Pittsburgh, but the download after preview fails to happen. I using Chrome on a Mac. Maybe I am using it wrong. I don't know.

Anyway, here are my feature requests:

1) See what a chart looks like immediately. Can be pre-generated. (Someone already said this in a previous comment)

2) Would like to annotate my chart with notes or custom title, subtitle, etc

3) Share chart on various social media sites as an interactive widget or simply a photo. (Someone already said this in a previous comment)

4) Print to a T-shirt or mug on zazzle.com or other T-shirt site (you can probably make money here as an affiliate).

5) This is a little crazy, but maybe overlay my wedding gift registry items on top of the star chart so that people can buy our wedding registry items in a cool and interactive way instead of navigating through multiple totally crappy wedding registry sites. (again you can probably make money as an affiliate here)... it's just an idea...

Good luck with the project!
That sounds great. Your family also has an advantage over those who go it alone because you can be more efficient with finances (we don't each need our own mortgage, interest payments, etc.) and you have more opportunity to take chances. While some subset of the family is trying a new startup, the rest can be earning money for the next round.

I tend to agree. Drugs are a big part of Rio's politics. Sadly.
> apt-get (did you mean aptitude? What's the difference?)

aptitude is a TUI front-end for apt-get (which is to yum as dpkg is to rpm). synaptic and the Ubuntu Store are GUIs into the same system, though I think the store is further layered over aptdaemon and/or PackageKit. (I don't use the store much, since I'm used to synaptic, so I'm foggy on the details there. At any rate, the store UI isn't blocked while installs progress.)

You can't moan at the guy for being subjective and then moan about your opinion on themes, release names, design decisions.

Wayland will come to Fedora as well as Ubuntu - an apt-get/yum install will no doubt provide that choice.

I like fedora as it's got Gnome 3 as a default, it's an open development (rather than large code dumps chucked over the wall ala https://bugzilla.gnome.org/show_bug.cgi?id=659693 ) and it's cutting edge/test bed for new stuff.
If they could do it, they would do it. There really is no point in announcing these sorts of things.

Discuss your issues with them. Tell them that you don't like the way things are going and that you believe that you should all focus on the things that really matter instead of minute details. Tell them that you should all think really hard for each iteration you make and that you shouldn't allow each and everyone's beliefs dictate everyone else's workflow. Suggest a simple process or methodology that will help you all find out the things that really matter and focus on them.

Plain, simple talking is underrated. If you won't let your voice be heard you will always be the pixel-pusher.

Mainstream media is in bad shape everywhere and Brazil is no exception. Unfortunately our media outlets appear to make extra efforts not to anger current government (whatever the current government is).

Actually, by releasing the content under a CC license, the author clearly chose to have this exact phenomenon happen. He may no longer wish to host the books himself, which is reasonable and acceptable -- but since the CC license allows republishing, this behavior by others is also reasonable and acceptable. The only drama being made by this action is by wonks like you who ignore the basic facts of sharing based licensing to cop some sort of bs superior attitude.
Some tiny details seem to make a big difference for me:

- A clicky, model-m type keyboard makes it easier to type effortlessly

- I find i get full-body rigidity when i try to do precision tracking with my mouse. That's why i love the alt-click to move/resize conventions of linux window managers which unfortunately i cant have anywhere else

- An ipad is a good excuse to get up and read that article walking around instead of sitting

- Good lighting , and a window in my visual field so i can fixate at distant objects and rest my eyes. f.lux also helps

- More than 1 monitors are eye sore, i prefer 1 large screen

The sustainability hypothesis is broken.

investment in VC firms also lags investment by VCs. As a result, you can't look at the fact that deployed capital currently exceed AUM and conclude that somehow the trend will continue. I fully expect VC firms to raise more money as there are more investible opportunities.

To put it concretely, there is a state of the world in which VC firms leverage up (at very low rates), reducing the amount of money they need to accept upfront. Imagine that the firms arranged for a 2x leverage scenario. Then, they would only need about 7.2 B to service the 14.3B investment, much less than the 8.1 B invested

And as far as market moves are concerned, the fact that even smart money is getting slammed in the market moves suggests that most asset classes are poor short-term investments. And for those things that are doing well (e.g. gold), margin pressures and other actions (e.g. redemptions) are slowly forcing people out of those markets. In fact, he admits as much: " A number of sharp daily swings highlighted the volatility that makes venture capitalists and other investors nervous about investing." nervous about investing in equities and derivatives markets, not in startups which aren't subject to the whims of the stock market.

Finance minus the middlemen
Finance is being disintermediated. The old finance value chain is giving way to direct connections between providers and consumers. Large monolithic finance companies can no longer own content, distribution or even their customers. Peer to peer lending, microloans, lending clubs, donation sites, knowledge networks, personal finance managers, virtual currencies, you name it, every area is under scrutiny and Entrepreneurs are seeking out inefficiencies that they can address with new mobile and web technologies.
Flywheels for energy storage -- Pros and cons as compared to batteries
@zohebv there are several errors in deduction here:

> a multithreaded environment eventually ends up introducing several blocking I/O functions

really? multi-threading and non blocking io are two separate tools and one doesn't have to choose one of them exclusively. they can be intertwined, boost::asio allows you to run a single async event processor on as many threads you want. all without doing any explicit locking. if you're averse to locking (which based on your experience seems to be the case) you're taking things too far by avoiding threads completely.

> You are basically asserting that async programming has no advantage over any other approach whatsoever

i don't think anyone's asserting that. the original argument made was - if all you have in one process is a tight loop dispatching non blocking io handlers then you can't handle computationally intensive tasks. of course, you can spawn 40 other process - but i don't like a model where that's your /only/ option. there are middle grounds and any system that discounts them is short sighted.

> Trying to say that async programming is useless

yet again. i don't see that being said anywhere.

> Node is an asynchronous programming framework bundled with a largely async library ... If you have done any kind of systems programming, you would know that availability of asynchronous I/O is a life saver

now, if you'd indulge me with my own escapades in logic and word play.

I wake up, sometimes get my laptop and read something while I am in bed. Sometimes I get up to read. I check my FB, email, and then HN, BBC, Economist etc. which takes about an hour or so normally. I eat some cereal while doing that - must of the time Honey Bunches of Oats.

Then I get to work brainstorming, emailing, brainstorming, speaking with my programmer, brainstorming, and then lunch. In the afternoon/evening I usually go to the gym or sometimes play soccer at lunch.
How To Find And Choose An Idea For Your Project
You may need to cancel your AT&T plan for iPhone 4S
You may need to cancel your AT&T plan to upgrade to 4S.<p>For instance, Apple.com says I cannot upgrade my phone at normal pricing until November 22nd. Otherwise I have to pay retail for the phone (and signup still for a 2 year contract). So pay several hundred dollars more for not waiting a month.<p>On the other hand, you can simply cancel your AT&T account and then reopen your account to buy the iPhone 4S at normal pricing. And pay an early termination fee in my case of $65 and possibly $30 setup fee. Still several hundred dollars less.<p>I use Google Voice so losing my number makes no difference and I am not on the unlimited plan.<p>Why won't AT&T simply let me pay the early termination fee, change my number if they want, and let me preorder at normal pricing at Apple.com?<p>I contacted AT&T support and they said they do not know when the iPhone will be available. I sent them a link to Apple.com's site where it says when it's available. They said they don't know how much my early terminiation fee would be and I resent her the link to website calculators that show you how much it will be. So after a long conversation she agreed yes technically cancelling is the much cheaper option but did not seem happy to admit.<p>Hope this helps others out there!
If you have an hour to spare and Flash player installed, Bogost gave a talk about Cow Clicker at the Game Developers Conference, shortly before the "Cowpocalypse" mentioned in the article:

http://www.gdcvault.com/play/1013828/

It's been a while since I watched it, so I forget whether he actually highlights his ambivalence toward the game, but it's more than obvious in the way he talks about it.
Yes, games are too expensive. I can't understand why RAGE, just released a few days ago, would cost $60 on Steam. You can sort-of get away with it when you sell at brick-and-mortar stores, but digital distribution should cut the costs dramatically. Instead, you have to pay $60 to get a game on digital distribution when it comes out. That's why I wait for Steam sales. Occasionally great games that came out a year ago are on sale for a reasonable price.
What is the right way to create community and credentials for self learners?
This is almost my set up exactly. My parents got me an Aeron when I graduated college, and I recently went to three monitors. Three really is the sweet spot -- I keep Emacs split vertically on the middle monitor, a series of Chrome tabs open on the left screen for reference, and a mosaic of terminals on the right.
As someone who doesn't own either but is looking into a more expensive chair, can you clarify either of those sentences?
Yeah, well the other idea might be to just sit back and accept the $30K per year. Within a year you will have a return on your investment so long as that third party continues to advertise. Bulls make money, bears make money, but pigs get slaughtered. Careful you do not overload your site trying to make money!
This is a fascinating article looking at the somewhat low-tech (at least in its early incarnations) flywheel for energy storage, relative to batteries.

The charts are great for comparing the Specific Mass and Specific Power of different devices. In particular, while traditional batteries can store more energy in a smaller place, flywheels show promise when energy needs to be quickly absorbed or deployed, for instance in breaking / accelerating.

I was awestruck by this statement:

"[A] flywheel with 1 kg and occupying about half litre could store the energy needed to bring a car moving at 100 Km/h to a standstill."

The article also mentions some interesting tech involved in the newest flywheels: interesting materials and magnets to reduce friction.
dlikhten quote: Nobody realizes that the button does nothing.

I wanted to point out that the door open/close buttons definitely have a function when the elevator is operating in emergency mode.

Allow me to expand further with an example scenario:

First off, an elevator's emergency operation mode is engaged by using a key. You may have noticed the keyhole before in an elevator car; it is typically located near the floor selection panel. It is primarily used by firefighter's or emergency personnel, in order to take control of the elevators.

Next, imagine a hypothetical elevator situation. The elevator is in normal operation mode. You step into an empty elevator car at floor 1, and you select floor 14 as your destination. Someone else enters the elevator car with you, and selects floor 3 as the destination. Now, floor 3 and floor 14 have been selected and are illuminated on the floor selection panel.

Assuming no other factors, the elevator car stops at floor 3, the doors automatically open, and the person that selected floor 3 steps out. But wait... you decide to step out too, because you need to hit the restroom. As it turns out, no one is entering the elevator car that you and the passenger just exited at floor 3. The elevator car is now empty.

What happens now?

The doors automatically close. No one is on board the elevator car that you just exited, and floor 14 is still selected. This is immutable; assuming no other factors, the elevator car will eventually make it to floor 14, or be stopped by other passengers that are waiting for that elevator car before it gets there. In either case, the elevator car is out of your control.

Now, think of it from a firefighter's perspective. A firefighter does not want to be in a scenario where the elevator car is capable of leaving a floor, without his or her express command, regardless of whether the elevator car is being called by someone else, or if a floor has been selected and no one is in the elevator car.

This is what the door close button is for when an elevator is in emergency operation mode. In this mode, the desired floor is selected, then the door close button must be fully engaged and held until the elevator car begins to move. If the door close button is released before the elevator car begins to move, the doors will automatically open, and the elevator car will remain on the current floor.

In emergency operation mode, when an elevator car arrives at the selected floor, the doors will not automatically open. The open door button must be fully engaged and held in order for the doors to fully open. If the open door button is released before the doors are fully opened, the doors will automatically close. This functionality is designed to allow a firefighter to partially open the doors in order to assess a situation (e.g., fire, smoke, etc.), again, at his or her express command. Otherwise, the doors would automatically open fully, potentially exposing the firefighter to flames, or quickly filling the elevator car with smoke.

I would love it if that were true, but on the whole people in the UK hate to complain, at least to anyone who can do something about their complaint.

And our politicians should all be shot. I'd like them to do something more then slag each other off.
Yeah, you have to discuss your issues with the additions. If they are non-technical then you can make up some story about the world exploding if they go through with it...

...I'm a non-technical co-founder and I DO micromanage, but I keep an open mind if my programmer says it is more difficult, harder to implement etc. We have a good relationship with that type of stuff. Marketing/business people have reasons for where they put buttons etc., but you need to get on the same page with him about projects that can't be added.
