I've done email marketing for some pretty big companies over the last 3-4 years, as well as a few smaller ventures. When it comes to generating revenue, HTML wins across the board in my experience with general goods' EC, daily deal, education and food.

The users of this board aren't exactly the type of people who impulse buy.
What are your thoughts on Mozilla's http://openbadges.org and have you considered integrating with them in some way?

A single unified badges project would be very useful for online education as a form of showcasing accumulated knowledge and credentials.
Ben is one of few modern day startup founders who actually give a damn and take the time to respond to customer queries. We live in a society where the startup industry is overpopulated by pretentious Harvard drop-outs who think they have some kind of sense of entitlement and are revolutionaries. It's refreshing to see Ben is anything but a decent, humble and respectable guy who finds the time to write a well-thought out response to even the toughest of critics.

I tend to use Campaign Monitor for emails, but this makes me want to try Mailchimp because I've never fully given it a chance and the fact the company is being run by a decent guy makes me even more motivated to do so.
I just sat here for like two hours... Thanks.
>Fortunately this is counterbalanced by the Oberth effect. Getting to 20% of your orbital velocity requires expending 20% of your rocket's delta-V. And since delta-V is logarithmic in your propellant mass (rocket equation) that could easily translate to needing half as much fuel.

Well, that doesn't really address my point, which was that you need to compare the weight of the hybrid engine to the weight of the extra fuel. The first problem is that an air-breathing engine is going to be something like 3 to 5% of the initial mass, and you have to carry it with you to orbit[1]. The second problem is how the fuel scales:

v_hybrid = 0.8 * v_conventional

Assume both have similar engines:

ln(m_hybrid-initial/ m_hybrid-final) = ln((m_conventonal-initial / m_conventional-final)^0.8)

m_hybrid-intial = (m_conventional-intial / m_conventional-final)^0.8 * m_hybrid-final

let delta equal the expression in parenthesis

m_h-i = delta^0.8 * (m_payload + m_engine) = delta^0.8 * (m_payload + m_h-i * 0.05)

m_h-i * (1 - 0.05 * delta^0.8) = delta^0.8 * m_payload

So the fuel load in a hybrid is going to be:

m_final = delta^(1-0.2) / (1 - 0.05delta^(1-0.2)) m_payload,

The factor in the denominator is what really kills you, and the hybrid is only going to give you a net benefit for deltas less than about 15. So, not only is there not a factor of 2 fuel savings, there isn't any fuel savings at all! Even if you assume an engine weight of only 3% of initial mass, the benefit is only for delta < 35, which is better than just about all actual (as opposed to paper) launchers. By the way, the Shuttle had a delta of about 85-90 for LEO precisely because its designers made the decision to bring wings (which we neglected above) along for the ride to orbit. That also contributed to the 1 in 50 accident rate of that launch system.

And none of this addresses the fact that you are optimizing the f*ck out of one of the least expensive components of launch cost by introducing all sorts of unnecessary complexity.

[1] Ok, I suppose you don't, but then you have to have some way of recovering it, and that adds an enormous amount of complexity to the system.
Hmm.. thats not a oneliner. Which is what makes the Basic version interesting in the first place. Also it differs in that it does not run continously.

I shortened it a bit:

Still not as elegant as the Basic version.

Patently and laughably false.
Maybe it depends on the level you're going in at.

I went through an Amazon interview process that had the nickname "the round". It required that I speak to 12 unique people during the process, and as such required 14 interviews (most face-to-face, some phone). Those were with people at the same level (architect), people above the level (a board member/leadership), people below the level (principle developers).

In addition to that was a 5 hour technical test that I found really good fun. The first hour I was totally stumped as to how to even begin, so I took a tea break out of frustration and nerves and found that I then completed it in around 10 minutes.

I found the test fascinating... a very simple thing that tested a lot of the basics in one go as well as how you might solve a very obscure and rare problem.

I won't share details on that test out of respect. Hiring is hard and I'm sure that they are re-using that technical test.

At the end I didn't get the job as I was "too technical" and the position was for a solutions architect and would have involved lots of customer contact. But I was offered an equivalent developer track position, though unfortunately I personally feel my strength is to always be listening to customers, so I then declined.

The process was interesting though. There were good questions, the interrogation of knowledge at a very deep technical level, and most of the face-to-face interviews included some technical element.

Because I hire too I find going through interviews to be a rare chance to deconstruct someone else's process and to try and gain an insight into what they look for.

I do not think that the higher level positions at Amazon would be "no trouble", the interviewers knew exactly what they wanted and the process was an enjoyable challenge.
Great talk.

Gates's foundation has made a handful of bad investments (generally small) but I'm generally really impressed with the thought they put into where to invest and why.

While it's a little bit scary that Japan and Germany are both trending (more than trending) away from nuclear, maybe that's not the worst thing in the world. Neither country will go for coal. Both countries will need to invest in other technologies (some basic, some consumer-oriented) in order to meet their emissions reductions goals.

But I get scared about the possibility of additional countries backing away from nuclear.

Is that an offer to pay all the external costs of nuclear power? I mean, all of them. From final deposit, over insurance policies in case of a meltdown to environmental consequences of the entire nuclear supply chain?

Nuclear power is just too expensive for an economy. Nuclear power is limited, there is just not endless amount of uranium on the planet. Also globally nuclear power is pointless, IIRC nuclear power has a global market share of 6% for primary energy. Too believe it could solve our energy needs sounds weird to me.

Also nuclear power is inefficient. Efficiency is usually way below 50%, since nuclear power plants are far away from anything you can't usually use the heat an nuclear power plant produce for anything productive, so it's lost.

But of course there are new and better plants in development, they are safer and bigger and produce less waste. But the old plants still exist. You can't replace them within a few years, it takes decades. And the costs for such a programme will be very high.

Since 2005, there is a nuclear power plant being build in Finland, called Olkiluoto III. The reactor was priced at three billion euros, currently the price increased to about six billion. The reactor might go online in 2015, a decade after the construction started.

The reactor will provide 1600 MW of electrical power. For comparison, in 2011 alone wind power plants were build with the combined power of 9600 MW (Europe wide, Germany about 2000 MW, GB about 1300 MW).

I know, this is not directly comparable but it gives you a hint, that you could have easily get the 1600 MW in ten years with renewable sources.

Nuclear power might be an interesting technology, but for me it is just a steam machine, which leaves a huge pile of waste behind. Nobody knows how to handle it, and people got it wrong. Search for Asse II if you want to know more about it. For Germany it will be very hard to find a safe final deposit for all the nuclear waste.
This was destined to happen sooner or later. Sooner it now seems. I spent a lot of time in those chat rooms, but they have more than been proceeded by the webs current offerings.
I have been told that these "perks" make sense if you are a young (starving) grad just out of school for whom the idea of anything that is not Ramen or Cold Pizza is heavenly. However, when you get older, you find that cold cash can pay for things like diapers, child care and that additional car that your family needs.

Congratulations, you've just discovered one reason why the free market isn't the best system to organise basic science research.
This is very impressive.

I got further with this in fifteen minutes on my iPhone lying in bed than an hour last night with the Windows Phone 8 SDK.

The APIs seem nicely designed and the interface works surprisingly well on a phone. I haven't seen anything else as likely to democratize programming since Click 'n Play back in the 90s.

It would be nice to see some kind of automatic wrapper facility for the full API, even if the syntax became necessarily horrible and it was hidden behind an expert panel. Sooner or later every large project will want to step beyond the bounds of the current garden, I think.
What benefits do the new satellites bring?
> But as an aside: is it really typical for someone to prepare this hard for an interview, even if it is for a dream company? If so, then something seems to be clearly broken with the interview process. My idea of a superstar candidate is not someone who memorizes possible questions and answers, but simply someone who is really really good at what he does.

The problem is that the google process tests how good a computer scientist you are. Irrespective of how good you are with the fundamentals, the fact of the matter is that is most software engineering jobs don't necessarily involve that much algorithmic knowledge and essentially are all about glueing complicated systems together. Irrespective of how much practice you have gotten in the past, practice for an interview is unfortunately essential. The process is broken and people just believe that copying the Google process will help which really doesn't.

When the market is commoditized and ready for standardization.
Standardization that understands the practical difficulties of current development model would be a huge advantage. In your case, standardization of data access (RDBMS/NoSQL), multitenancy & stateless/stateful scaling.
Standardization pushed for the sake of it will end up like SOAP (vs REST) or Entity beans (vs Hibernate).

The Organism Will Do What It Pleases
Kirk Sorenson has calculated that in a new molten salt thorium reactor, the thorium burned would be worth 5x its weight in gold, based on 10 cents per kWh.

I am a huge advocate of thorium as a fuel. Unfortunately, using thorium in any reactor today only gives marginal benefits. The CANDU reactors in Canada can and do already take thorium in their fuel cycle.

In the long run, you only have to store the waste for 100 years before it is safe. This is because you can re-use the waste, creating further efficiency and less storage time.

China has stockpiled thorium since 1999, and started a MSR program in the past few years. That shows how far behind we are in this tech, even when we pioneered it (I am referring to molten salt technology). The head of the program got a phd in electrical engineering from Drexel. Oh, and is the son of some finance? minister as well, so it definitely has the political clout to be accomplished. China desperately needs clean energy - they are making water plants, for coal plants, for manufacturing plants. And each of these stresses out the environment in so many ways, it's very risky to the long term health of the region. Visit circleofblue.org to learn more about the water-energy nexus.

And sorry, but not really a step closer. Everyone in the nuke world has known thorium can be used. Like I said before, it will only provide marginal benefits. Did you know, thorium is 3-4x more present in the earth's crust than uranium?

If instead of those loans to all those solar companies, and put $50 billion to a Thorium program, and made a space race effort, I can confidently say we would be energy independent in 10 years. Five years to develop, Five years to build. With all these new advances in materials and alloys (which was the main issue), there would be very little problem. Instead, we are making private companies do this, by specifically targeting military applications.

How sad would it be if Thorium molten salt technology was developed in the US, and we sold it overseas first?

In fact, with lower competitiveness among applicants at other companies, I could demand a higher salary, and then use that salary to buy gourmet food/coffee and pay for Instacart to get the same grocery delivery services you get for free at Google.

Google pays me more than I made at an investment bank as a contractor, so I don't really think I'm giving up anything. I get free food and enough money to pay someone to cook for me if I wanted. (The food at Google is pretty nice, though, so I don't have to do that. We have five different cafes in the New York office, so there's always something good regardless of your preferences. Even the strict vegans get multiple options!)

But I disagree with your premise: I don't think firms with low-quality applicants will pay you more because you're a high-quality applicant. How will they recognize your value-add if they've never seen it before?

(As for coffee giving you indigestion: the reason Google provides coffee is because people want it. If you want something else, they'll give it to you. The idea is to keep you engaged and focused on work, not to make Google appealing to coffee snobs. Though with Intelligentsia, Stumptown, and Gorilla coffee, it is pretty darn appealing!

I think what is meant is that 90% are rejected at the phone screen, and the top 10% or 1% are of those who can code, ie passes the phone screen. That makes them 1% or 0.1% of your initial applicant pool.
I'm more scared about countries who start using nuclear power.
Your second paragraph here is actually the root of my argument as well! I agree strongly. Content is inevitably going to be product for the direct Internet market, and that model will eventually supplant the pay TV model.

HBO is itself effectively just a middleman (at least for most of the content we care about). Maybe we should stop talking about what HBO should do, and start talking about what companies like Blown Deadline (David Simon's production company) should do. Again, my sense is that many more potential viable productions exist than are greenlit by AMC, FX, HBO, and Showtime.
He generated his own motivation: His external motivations were bought with his own money. Why is this a problem as long as he gets the job done? Everyone gets motivated by something: After all, as an employer, surely you do pay your employees, don't you? That does act as some sort of motivation. Otherwise, they would be all working for you for free just driven by all that "self-motivation".
Still, I wouldn't say this http://imgur.com/pUlXu is the best way to drive adoption amongst the Microsoft faithful. Yes I know they need to draw the line somewhere, and IE9 (maybe IE anything... haven't tried 10) sucks, but this is quite a departure from the general Windows stance of "backwards compatibility at all costs" (why their hosts file still lives in an 'etc' directory is beyond me, for example).

Additionally, if you have cookies disabled it just sits there on the loading screen (in FF 17 at least) - I thought it was just broken at first.
This article is completely accurate - there's nothing new or innotivative about fusion drive when compared to what was in the market years ago- it's pure marketing. I know the anti apple tone of the article made it seem unfairly biased, but it's totally correct in this case.

>I would say that their real competition is Google/Samsung

Having just picked up one of the new ARM based Chromebooks, I am inclined to agree. Until now I have never fully appreciated how complete Google's offerings are, from paid apps in the Chrome web store to paid movies on YouTube... to say nothing of the inventory size of both.
> This article is completely accurate - there's nothing new or innotivative about fusion drive when compared to what was in the market years ago- it's pure marketing.

Pardon me but it's the first time ever I heard about tiered storage (not caching hybrids which is handled by the drives themselves) being available outside of datacenters. Doesn't explain the +250$ price.

Besides, the whole tone of the article is full of useless hatred. The point could have been made without such aggressiveness.

What's more, the proposed solution is ludicrous:

- buy an external SSD

- install OSX on it

- wipe the internal disk

- manually manage files/applications/whatnot to be stored on the SSD or the disk.

I can't even begin to describe how such a scheme is brittle and contrived.

Can we stop pretending everyone out there is technically inclined? To us technical folks who know how to actually build the CoreStorage tiered array, 250$ may look like a steep price, but to the huge amount of real people out there, the convenience is well worth 250$, and for those it's not worth, well they'd stay with a spinner anyway.
This is a re-release from MS their secret weapon; http://rise4fun.com/. MS research is really good and they are working on important things other companies ignore.

If you are sending emails to business clients support for Outlook 2000-2003 & Outlook 2007 is still essential. I'm afraid you need to code them like it's 1999. MailChimp have a guide on how to do it right:

Fortunately a <table> is (and always has been) responsive.

For non-business clients (who would be unlikely to use Outlook at all) these look great.
People are willing to pay for supersonic flight. Concorde made a profit on most of it's flights, and it was only after the World Trade Center attacks and subsequent downturn in international commercial flight that it became a problem. Also, because not many Concordes were made, the R&D costs were never properly amortized.

The sonic boom however is an issue - Concorde was limited to a small selection of routes that passed mainly over water (e.g. London -> New York) because it was not allowed to go supersonic over a lot of countries. If you could fly supersonic all the way from London to Tokyo, or San Fransisco, or Sydney, then I'm sure it would be worth even more.

I think many nuke advocates go much too far in the "nuclear power will solve all our problems!"

That said, the strongest arguments for nuclear power has always been as part of a balanced energy diet, not as the off the shelf answer to everything. So, how do we figure out where it's appropriate and where not?

Properly price carbon, and remove all distorting subsidies to all forms of energy, from fossil fuels to solar to wind to nuclear. Then let the market do what it does best: figure out the best way to allocate capital to produce goods.

Nuclear certainly needs proper regulation and safety requirements, but contemporary designs are much lower risk than the Fukushima reactor from the 1970s or the ancient design of Chernobyl: despite that, they're nearly impossible to build. I've heard it wouldn't even be allowed, in the current regulatory regime, to replace those old plants with new ones. Something's broken there.

Fusion Drive is just one of many options available. You could get even better performance from a RAID array of SSDs.

Most of what people pay Apple for is sorting all this stuff out, while many of us are capable of creating all sorts of hardware stacks most people just want something fast that they can store lots of stuff on, fusion drive delivers that.

To consumers it's a tradeoff between price and management, and to be fair for most people an extra $250 is probably well worth it to them vs. how complex managing that storage is to them. Fusion Drive is sold on consumer surplus not commodity.

Consumer surplus is the same reason programmers are so valuable to the economy, industry would rather pay someone else to figure out all this complex technology than invest the time in learning it themselves and saving themselves the cost of a programmer.
