Presumably you mean gross margin, calculated as revenue less cost of goods and excluding payment fees.

For a $100 sale that costs $75 (a 25% gross margin, typical for internet sales), and a payment fee of 5%, the fee is $5, or 20% of the $25 gross margin. Each 1% of fees represents 4% of gross margin. That fee will represent a much higher percentage of net profit, after deducting other business costs.

This effect increases dramatically as gross margin decreases. At 20% gross margin, 5% represents 25% of margin.

For a low margin business, say 10% gross margin, a 5% fee represents 50% of the $10 margin on a $100 sale. If other business costs average $3 on that sale, the payment fee takes out $5 from the $7 margin, or 71%. A 1% decrease in payment fees increases net profit by 50%, from $2 to $3 on that sale.

So you can see on low margin business, payment fees have an enormous effect on margins and profitability.

Wolfram Alpha has 10^46 J as 100x the energy given off by a supernova. I don't know if that means your numbers are off, or if this star is just mind-bendingly insane.
A core difference here is the contextual and semantic understanding of the code. The way we search and rank ties into alot of coding metrics and semantic parsing of the code around the web using the new 'Roslyn' C#/VB compiler-as-a-service technology.

Most other experiences base their search algorithms on search engines / textual matching / rely on the host web site's search accuracy, where as we combine search engine smarts with semantic and contextual analysis.
What about Mono? I have no idea how practical this is for real code bases, but I've used it successfully on several smaller projects.

Yes, those terms fail to correlate to brain activity. But that doesn't mean that there's not a real, subjective quality to different kinds of productive mental activity. Working with your hands (and with shapes or sounds or patterns) is a great way to take a break from doing heavy semantic/problem-solving thinking, and it has the crazy side effect of gradually giving you skills you probably wished you had.
Most every command that can be done with a gui can be done via command line, mostly powershell; which you can use remotely. In fact I would be hard pressed to find any administration routine that cannot be done through command line and is not documented.
Nice digging.

This hit the BS detector for me too, mainly because it goes against some of the rules of thumb I have found useful for optimization. For example, the need for smooth and stutter-free ui notwithstanding, if something only happens in response to user input you are less likely to see important gains from this sort of CPU microoptimization. Even on a very old machine, it should be obvious that the computer adds integers much faster than you can move your finger (otherwise there would be no point of having the computer, am I right?) On the other hand, if you had to compute more on every frame or for a substantial amount of onscreen objects, that's where the real gains are going to live, because the numbers add up much more easily.
This happens "often" with public library books, also. That scenario happened to the wife of a coworker.

We used to have laws against debtors prisons but those have been gradually eliminated. The legal hack around creation of debtors prisons revolves around demanding the victims presence at a civil trial, no show results in warrant for contempt of court. The other maneuver is if someone owes you "something" as a civil lawsuit, if you can convince a judge to file it instead as a property theft crime, suddenly a simple civil matter converts into a criminal matter.

> "I'm sure they neither knew nor cared"

They did, actually -- Pytheas had observed that true North was "devoid of stars" way back in 320 BC. Polaris didn't begin to be recognized as the "North Star" until much later (10th century according to wikipedia), because it wasn't particularly close. Navigators learned how to find where north was from several stars; it's only been the last several centuries that Polaris has been close enough to North as to be treated as the default for navigation.

They also knew about precession (credited to Hipparchus in the 2nd century BC, but possibly an older discovery.) So they knew that north wouldn't be in exactly the same place centuries later. Differences of a few degrees were a pretty big deal to people who both navigated by, and gave religious significance to, the stars.

I don't know the details of early Sumerian astronomical navigation schemes. From what I understand, our knowledge of their astronomy comes from Babylonian sources a couple thousand years later, and is not particularly detailed or reliable.
Building Chernobyl's New Safe Confinement
Uhh no. AirBNB has a field on listings that clearly indicates "Bed Type". In this case "Bed Type" said Real Bed.
Random example:
https://www.airbnb.com/rooms/1229577?checkin=02%2F21%2F2014&...

One isn't likely to clarify that with the host prior to arrival given that it's on the listing. AirBNB needs to take responsibility for this kind of thing given that you pay about 15% as AirBNB fees and 3% is also paid by the host. Refunding just the fees isn't what you pay the fees for. It is to take care of situations such as this.
In fairness, you do tend to hear horror stories about charity drives and such getting shut down by Paypal (and it would be nice if there were actual non-shady competition in that space).
On a similar note, there is also csvkit [1] for csv files. It is not quite as full featured as I had like, but it is easier than manipulating csv content directly via cut/column/grep/sed.

Are you kidding? You need to be rather computer literate to gamble with bitcoin, and you have to be aware that gambling with bitcoin exists, and you have to buy bitcoin which is still a high bar just by itself.

The high bar to bitcoin gambling is evidenced by the fact that relatively few people are doing it, for how many people love to gamble. Bitcoin gambling is astronomically dwarfed by other forms of gambling. It's a fucking rounding error.
It's neat to open HN and see very relevant topics. I'm taking Chris' Contextual Electronics course. It's structured around an 8 week period, but fortunately for me, it's still effective going at my own pace since life & work has been busy. Congrats Chris, and Thanks!
It is a big deal because the listing clearly indicated that the place has real beds and accommodates 4 people.

I would expect AirBNB to take responsibility given that the incorrect info is on their website and you pay pretty hefty fees to use the service. (AirBNB charges about 15% to the tenant and 3% to the host so a total of 18% - not bad ;))

I'm hoping the opposite, that people upgrading their routers to forward more than just IPv4 packets might mean we can finally start using SCTP in the real world. (It won't happen, of course, but one can dream)
I'm happy to see this reach beta version, it's a great step in the right direction. Grunt is too generic as a tool and we've all seen Gruntfiles reach enormous lengths, to a point when it's really hard to figure out what is processing what.

One thing that has room for improvement though is the syntax, which in my opinion doesn't reveal the intention behind some methods and is a bit too coupled with the implementation. What does `makeTree('lib')` mean? If it's taking a folder and its files then why not rename it to something like `broccoli.requireFolder('lib')`? Also another thing that might improve usability would be chaining compilers instead of calling them directly with the tree as parameter.

These are just minor things anyway, I'm sure the library will improve over time. Congrats joliss, great fan of your work!
Can you explain what is stuck at Gox? Is it peoples bitcoins or their cash? How can they get them out to trade to other people and if they can why are they valued lower than normal bitcoins?

Look, shit happens, and handling it is part of being a professional. It's silly to ding you at this point for having to recruit under time pressure and artificial constraints. You play the hand you're dealt.

On the other hand, let's nobody pretend that time pressure and artificial constraints are good things, or a natural part of the recruiting process.
A Showcase of Creative Startup Logos
One thing that I cannot find on AirBNB is how to post a review and attach photos to it. Is it possible? On several occasions the apartments were not even remotely the same as in the photographs. (For example, on photos they look spacious and clean, in real life they are not.)

Amazon customers can upload their photos of the stuff they bought. This functionality is really something we need.

I think that AirBNB by doing things like this gives the hosts too much power (which in turn they abuse).
On the flip side, as an Airbnb host myself, I have had to cancel a guest's reservation before. It was because of reasons beyond my control (ie. being sent a warning fine from my HOA). Losing the 3% isn't the only thing that happens. #1. You also get a "review" on your listing and profile that says "Host canceled booking X days before arrival". #2. Airbnb drops your listing ranking, meaning you won't show up as high in searches.

Frankly, it's a bad experience for the host and guest, which is why I'm not convinced it happens all that often with hosts who have more than zero reviews. If you book a place with zero reviews, I think it's MUCH more likely to happen, as newer hosts are probably less likely to understand how Airbnb works.

I don't think it's worth mentioning Mono. It's impressive what they've managed to accomplish, but it's nowhere near being a true replacement for .NET, especially for any serious system.

I've been traveling for the past two years, and fortunately have only had positive experiences with Airbnb. I agree that some hosts can be less responsive others, so I've taken more time on my end to have a bit of back-and-forth with the right ones before booking.

Paul does make a good point regarding host cancellations, and your suggestion to publicly display acceptance or cancellation rates might be helpful to prospective guests.

That no-randomness mentality is a bit odd, but I admit that some games don't integrate it well. In Catan, I think the random element is well-done because it is the board and its distribution of resources that is random, not so much each player's turn.

I'm not sure what a "German aesthetic" would be in a card game, but one Austrian trick-taking card game that is a lot of fun is Schnapsen. The cards are random, the trump is random, and you draw cards each turn adding temporal randomness, but outwitting the randomness (and your opponent) is part of the appeal. It's slightly complex (a bit more than Hearts), but still way simpler than Bridge. Each round is fairly fast (5-10 minutes), and you can play a match (to 7 points) under an hour.

Apparently, it's called Sixty-Six (Sechsundsechzig) in Germany, though Schnapsen is a variant.

That's probably because at that time (more than 30 years ago) I was trying for photorealism, and I perhaps shouldn't have been -- I didn't have the skill. As a result, my drawings from that time all have that somewhat spooky aura.

Okay, but there are also practical concerns, like those of us who use map and compass in our lives (for me, geocaching and hunting). It's very well to wave your arms and talk about being a "mind-having individual" but it won't help you navigate in the Coast Mountains.
My understanding is that both bitcoins and cash are stuck at Gox. But you are still able to do internal bitcoin transfers within Gox. Person A transfers their "gox" bitcoins to bitcoinbuilder.com's "gox" bitcoin address, person B transfers their "real" bitcoins to bitcoinbuilder.com's "real" bitcoin address, bitcoinsbuilder.com transfers the "gox" bitcoins to person B's "gox" bitcoin address, and bitcoinsbuilder.com transfers the "real" bitcoins to person A's "real" bitcoin address. No bitcoins enter or leave Gox, they just trade hands within Gox using bitcoinsbuilder.com as the intermediary.
It makes me sad because most of the births are in underdeveloped countries, where people have no access to clean water and healthy food. And as more people of countries like China enter middle class, the resources we depend on, will diminish faster and faster.

I didn't initially understand from your post that you would have actually lost 50% had you cancelled yourself even months in advance. I agree that this does seem imbalanced.
Extending native prototypes creates other less obvious hurdles for libraries too. Craft.js, es5-shim, Modernizr, MooTools, Prototype.js, and Sugar.js, to name a few, have all, at one time or another, added incorrect shims to native prototypes.

While Underscore is in a better position than those that extend native prototypes, regarding api/environment conflicts, it can still be tripped up by poor shims because it defers to many ES5 methods if they exist. For example, if Prototype 1.6.0 and Underscore.js are included on a page Underscore's `_.reduce` method won't work properly. This is one of the reasons why libs/frameworks like Dojo, Ember, Lo-Dash, RequireJS, Sizzle, and YUI do native checks too.

User Acquisition at Virool (YC S12)
In a marketplace model (e.g. ebay, airbnb, amazon, seamless / any food delivery), the take rate generally falls between 10%-20%.

Credit card processing fees are somewhere around 2% - 3%, so in a marketplace with all credit card transactions, impact on margin will be 6% - 30%.

If that marketplace can implement alternative payments (e.g. ACH, bitcoin, etc), impact on margin can get down below 5%. Not sure how the ebay / paypal integration influences this - would be interesting data.

One additional method to reduce margin for marketplaces is to allow transactions to occur offline and then invoice the seller based on a % of the total amount. Then your impact on margin will be exactly what your processing fees are.

There will be much different dynamics for different revenue models (e.g. as patio11 said, in SaaS, it is basically irrelevant).

So, I argue that % impact on margin is not a very useful metric unless you are comparing a specific revenue model in a narrow vertical.

Would you rather have $10B of margin with 50% going to processing fees or $1M of margin with 0% going to processing fees?

Except they refunded the fee... Honestly having used the service several times I can't say I have ever had an issue. However I have also been in contact with the host every time before arrival and discussed the accommodations. I can't imagine going to another country or something without even talking to the host. Either way it doesn't sound like it ruined the vacation.

Not to mention there are plenty of nightmare stories surrounding hotels, they are not perfect either.

The patch stops working much faster while ecig's effect never seems to wear off.

I can only assume that it is because the patch maintains a constant level of nicotine in your bloodstream causing tolerance to develop faster and it is unable to spike the nicotine concentration unlike ecig when you can take a deep drag.

Ecig gives a totally different feeling than patch. You'll definitely feel it hit when you take a long deep drag.
Another thing: the Chinese fleets of discovery were much larger and extravagant than any fleet in history.

http://www.digitalhistory.uh.edu/learning_history/1492/zheng...

Zheng He not only had bigger ships than the Columbus ships... but also had 300 ships at his command. (with over 50 of them being extremely large treasure ships). Zheng He's treasure ships had live crops and livestock growing on them. They were a fleet of ships designed to work independently, and go around the world.

Zheng He traveled west first, to India. Afterwards, he planned to travel east (potentially to America). But that is when the Emperors changed and cut his explorations short. Zheng He most certainly had enough provisions to reach the Americas in the early 1400s.
