Gross Merchandise Value is how much money flows through your system while Revenue is how much lands in your bank account. For instance, a payments processor like Stripe might have a GMV of $100 million while their revenue would only be the 3% commission (in this case $3 million).

A contract is a legally binding and enforceable document. A letter of intent is when one party outlines what they are likely or would like to do - with some bits of it being enforceable like non-disclosure agreements. A memorandum of understanding is a letter of intent signed by all parties involved - it is still non-binding. A term sheet from a VC is like an LOI - however, it doesn't actually happen until after due diligence, negotiation, etc and only official when signed.

Burn rate is the delta in your bank account. Expenses is how much money left your bank account and revenue is how much entered. Thus burn rate is expenses - revenue and is -1 * profit.

Users are people on your site. Customers are paying users.

Signups are how many people created an account. Active users are how many people logged in over a certain period of time.

Cash flow positive means you have more in your bank account than you did before. However, a kickstarter which raised 1 million would be cash flow positive but not be profitable as it has many outstanding obligations.

Churn rate is the percentage of your users/customers who left over a certain duration. Retention is 1-churn.

Involuntary churn is when the customer leaves because they go out of business or in the case of dating apps, no longer need your services. Voluntary churn is all other churn.

Gross refers revenue - expenses of the product. Net is revenue - expense of the product - administrative costs - depreciation - payroll taxes etc.

Top line is referring to gross while bottom line refers to net. Top line growth means more revenue and bottom line growth means cost cutting.
Every study ever done has shown that getting rid of carpool lanes is just about the worst thing you could do. All those people that were in the carpool lane are now in with the general traffic, and they're not carpooling. So there are even more cars.
Leaving it in the ground with today's technologies is very expensive in terms of opportunity cost. You can leave it in the ground, but people don't want to pay $5 per gallon for gasoline. The climate models don't show high costs to warming for at least s few decades.

Except now you're adding the traffic that was there to all the other lanes, and you're adding cars at the same time.

The key to traffic is to REDUCE the amount of cars on the road, not increase it.

Coal still produces more electricity than natural gas. There was one month recently when Mat gas produced more electricity but that was an anomaly. In a few years however, nat gas will dominate.
I agree that a congestion tax on its own would be regressive. It's essential that subsidized, high-capacity bus lines replace most of the cars.

This situation would result in a far superior outcome for currently poor people, even if it still has some inequality.
But they have restrictions that limit their functionality, so they are trading power for security...

Imagine this. I need read/write access of the host file or an equivalent functionality of mapping any arbitrary domain name to any arbitrary IP address.

There is absolutely no way to keep that secure while allowing it because the functionality itself can be used for the wrong reasons. You either allow said functionality or you don't. There is absolutely no gray area.
As to NoScript:

- from a linked Mozilla blog post:

> [...] A major challenge we face is that many Firefox add-ons cannot possibly be built using either WebExtensions or the SDK as they currently exist. Over the coming year, we will seek feedback from the development community, and will continue to develop and extend the WebExtension API to support as much of the functionality needed by the most popular Firefox extensions as possible. [...]

(https://blog.mozilla.org/addons/2015/08/21/the-future-of-dev...)

- then, from a link posted at the end of the Mozilla blog post (in an "Update" section):

> [...] One concern people have is that their favorite add-on is no longer going to be supported, especially add-ons for power users. Some of the ones being mentioned are:

> [...] NoScript, [...]

> We’re working with Giorgio Maone, the developer of NoScript, to design the APIs he needs to implement NoScript as a WebExtension. [...]

Planning to go public 18-24 months from now is like planning to get married before you've met your significant other.

The window for IPOs opens and shuts, and sometimes it stays shut for a long time. Especially for companies like Uber, which are new and unprofitable, albeit large and growing fast.

Rather than reading this plan as referring to actual events in the future, we should read it as Uber selling itself to bigger and bigger investors, since those investors are unlikely to see profit any other way.
You're forgetting ride sharing(i.e. uber's UberPool). by sharing rides , one can save 40% (or maybe more, inc case sharign with 3 passenger is available) of cost. And that creates a powerful network effect with the possibility of disrupting the private car.

Since this lower cost sharing dynamic might be appealing to passengers also in a world with self-driving cars, and such network effects would be a powerful effect against commodization for the self-driving car company - it's understandable why the SDC company might be willing to share profits with UBER , just to lock the market.

Of course that's one scenario, but in general, one would guess that UberPool will have some influence on the self driving car market.

It is sexist in the sense that it is a motivation mechanism completely biased towards men. However, there is no such thing as discrimination going on. These girls applied for the job and get paid for it. It's not like they are being called engineers. They are not engineers and it makes no sense to say that "they should hire female engineers" because that 1) is not always possible (obvious lack of women in the field) and 2) may not even help to solve the social problems that most male engineers suffer from (which is the goal of hiring those girls), since female engineers are not there to cheer boys up. This would be replacing A with B -- it's not the same thing.

It is sad, however, to see that so many computer programmers struggle so much with social problems. I wonder how our (I am including myself in this set) future looks like.
Vancouver is a much smaller region and has more of a cohesive topology versus the spare conglomeration of Los Angeles, which could be better described as the "downtown" of Southern California.

The majority of people living in Southern California commute via freeway, and generally many people commute 70 mile roundtrips across town or from the valley into LA, and than for nightlife or a trip to a favorite bookstore etc, another ~70 mile round trip across town is totally normal.

Until there's more jobs available near affordable housing, millions of people in LA will continue relying on the freeways. The train is being slightly expanded into downtown Santa Monica, but that's not really a big improvement for LA - what would help the most is better transit lines between the San Fernando Valley and LA.
There is such an exception. Straight from the horse's mouth:

I think reducing keystrokes is a proxy metric for reducing the time and cognitive load of accomplishing an editing task.

This is true. The zoning laws that led to suburbia were introduced in the 1910s and 1920s by well-meaning "progressives" who decried the ability of the rich to cloister themselves in country estates while the poor were forced to live among commerce in the city.

They won, and the result was the legislation of vast suburban "residential" zones where commercial business was prohibited, with minimum lot sizes and setbacks and minimum space between houses.
Yes, but that's temporary. As demand exceeds supply again (because we're running out of oil) then the prices rise and suddenly all these unconventional oil projects become feasible again.

The only way to keep that oil in the ground is to eliminate the market for oil at profitable extraction prices through very cheap energy alternatives.

It's very difficult to solve the problem through regulation because you need all the countries making up a sizable portion of demand to regulate together. The incentive will be strong for individual countries to defy global pressure to do so, because cheaper energy means more economic growth. So far we've seen very little in the way of effective regulation and I'm not optimistic for a change, the incentives for short-term-minded politicians are in the other direction.
In your example of Grasshopper then, they are basically giving you a steep discount with no commission in the hope that the LTV of those customers (and total new customer volume) will be worth it?

Assuming that is the case, I've seen this in a few industries with mega deal bundles. The deal company charges for the bundle with the hope that companies will offer them competitive deals for free (and potentially cut them in on a % of total deal sales if they co-promote it).

TBH, I haven't seen much success from testing these sorts of things myself (not yours necessarily, just generally speaking). The issue is always that they don't get enough volume to be really worth it for brands of a certain scale.

There's also the concern that people are buying discounts, not product, so I imagine there are a bunch of people that buy this for discounts off of a couple products, and ignore the rest. Depending on what a given brand would need to contribute to get listed in this, that directly determines whether it is worth it or not to get you all the assets, help with co-promotion, etc.
How DTA is this dominant at all is a bit of a mystery to me. It allows me to download sequentially names files in rudimentary batches yes but thats not exactly mindblowing tech.
It's a marvelous book, but a little frustrating as well for not quite explaining enough to calculate with, even super-inefficiently. Can't we get a correct formula for the propagator, including the four spin components? When I tried to fill that in from other sources I was snowed under by all the formalism or prerequisites -- yes, it's probably a short step if you already understand it or you're smarter than me.

If someone made a clear-but-impractical QED simulator using, say, lattice gauge theory, I pledge to sing its praises. (You'd expect this to be possible for general relativity too.)

This is simply the leftist version of the American exceptionalism thesis.

Whereas conservatives focus on supposed positive exceptional attributes of America, multiple generations of leftists have now promoted and developed the inverse: the idea that America is forever fundamentally broken (due to the power of big corporations, evil conservatives, Fox News, etc.), and thus certain problems that others can solve are deemed inherently unsolveable in America.

The solution is a 10x better energy source. And it's only going to happen if smart people get focused on it. Fluctuations in the price of oil affect funding, etc, but the people working on the problem are a bigger issue.

Elon Musk is doing his best to drive down the price of batteries and solar power. What will you work on? Baseload power probably needs nuclear. There are a number of nuclear energy startups right now.
> This is simply the leftist version of the American exceptionalism thesis.

Strange description, because pretty much every example I've seen of this has been someone on the left saying "Of course we can do better in this area, see how it works in <other country>!" followed by someone on the right saying "No, we that won't work here, because America!".

(Sometimes pointing to something that might arguably be a legitimate difference -- I'm not saying that this pattern is universally wrong, just that there doesn't seem to be anything leftist about it, if anything, it tends to be the opposite.)

The closest I've seen from the Left to this is the defeatist version "we could in theory do that here and it would work, but it isn't politically viable because America!." But, OTOH, I've seen that form from the Right, too, just on different issues.

This is a large reason why:

But what you listed also isn't all it provides. Imagine being 99% done with a 35.6GB download. If Firefox crashes, you get to start that download from the beginning. As if you hadn't downloaded any part of it at all.

DTA would recover and you'd download 1% of that 35.6GB instead of the entire 35.6GB.

That's a large reason to use DTA over the built-in download manager by itself.
Ya know, my initial reaction to this was pretty negative. As a developer, I don't like the idea of losing access to a more powerful technique in favor of a less powerful one. If I want to write an add-on, I want XPCOM / XUL, etc., at least as an option.

However, giving it more thought, I think this might actually be a Good Thing in the long-run. OK, it's a stretch, but hear me out... I've been a vocal opponent of this whole idea of making the browser a poor man's operating system for a while. I want a Web where browsers are really good at, well, browsing hypermedia, and other applications handle "application stuff". So maybe, in a roundabout fashion, making it a little bit harder to extend the browser even further, will encourage people to shift back to a model of handing off some kinds of requests to an entirely different app, rather than trying to shoe-horn the kitchen sink, bathtub, 3d printer, milling machine, jumper cables, semiautomatic pistol, bandsaw, swimming pool, and clown suit all into the browser.

Or maybe not. Hey, a guy can wish, right?

It's a term of the trade in the retailing (and by extension e-commerce) industry. It refers to the value of the goods sold. If a retailer sells a widget for $100 at 50% margin, then the GMV is $100 and revenue to the retailer is $50.
Small businesses are defined as 1-500 employees - I suspect that includes a fair range of company types. Lumping them together as a single thing strikes me as a bit disingenuous.

A quick search turned this up:

This shows all business types following roughly the same trend. 'services' [which would include software and property management] have the lowest 5 yr survival rate at 36% and mining the highest at > 50%.

This is data is from the 2010 census, examining businesses started in 2005 - likely a different methodology than the SBA used. This which probably accounts for the discrepancy from my SBA stats in the original post.

I'm being pedantic about a random part of their description, but Xen is not based on linux. It is a microkernel sort-of based off of Nemesis OS. The dom0 is not Xen itself, it is just the control domain. Linux is probably the most heavily used dom0, but it is by no means the only dom0 - Solaris, FreeBSD, etc, can or previously could be used as dom0.

That sounds nice. At my shop we have all of that except the live validation, and schemas almost inevitably fall behind.

I think the opposite is more likely: Firefox and Chrome using the same extension mechanism -- and, inevitably, that means two-way chasing on implementing APIs that prove useful -- means that even if the ability to do more complex apps in Firefox falls in the short run, the ability to more complex apps in the browser in general (or, at least, Firefox, Chrome, and their descendants and others who adopt the same framewoek) is going to accelerate over a longer term.
But if everybody's defining their own values, then a bunch of people are going to define their values very selfishly. That's (unfortunately) human nature. One could argue that Ashley Madison (to use a current example) with their slogan "Life is short, have an affair" is living this just as much as Martin Luther King. Once you remove morality, then you have nothing to give any positive direction to your values, because you have no basis for defining what "positive" means, other than your own feelings and thoughts.

> He felt rationality leads to values which benefit humanity as a whole.

Other philosophers would disagree. de Sade, for example. (Yes, he was a philosopher, and his writings and actions were an expression of his philosophy.) And even human history seems to show that Nietzsche was overly optimistic on human nature on this point.

In "The Abolition of Man", C. S. Lewis argues that rationality, by itself, can never give real values. That can only come from "practical reason", not mere reason, because it has to tie reason to values and emotions. (I'm not stating it well - go read Lewis. It's really short, only a hundred pages or so, and very readable, though it does take some thought.)
