I have been using this strategy since quite some time now to develop a frontend product. And then use the profits from that product to advertise and attract enough visitors that lead to at least 1 more sale - and create a perpetual traffic cycle out of it. (I'm writing a 60 page book on it.)

Some things I've learned from experience.

1. You don't want to use the Google Keyword Tool. Thats a good tool for keyword suggestions. Not for keyword bidding. You want to use Google's Traffic Estimator tool instead. You will have to login to your Google Adwords account to use it. (Adwords > Tools & Analysis > Traffic Estimator)

2. You don't want to use category defining keywords. You want to make it slightly long tail. Don't search for "crossfit". Search for "crossfit training". Don't search for "speed reading". Search for "learn speed reading". Why? Because Google starts minimum bids for category defining keywords from $1 - even if there aren't any competing advertisers on that keyword. This inflates the numbers in your formula.

3. After searching for a keyword in the Traffic Estimator tool, click on "Impressions" and hover your mouse over the cliff in the graph they show. That is the Max CPC you want to take while calculating your price. (http://i.imgur.com/upj77.png)

With the above steps, the CPC you get for learn speed reading is 41 cents. If you expect a 1% conversion rate, you need a product that sells for about $41 minimum.

If you go to the clickbank.com marketplace and search for speed reading, you will see that the most popular product on speed reading (Quickeye Speed Reading Software) is infact priced at $47.
Good post, though, I should point out that some companies might not have the time to let a developer get up to speed on a particular technology, they they haven't used before.
So how would you go about learning LC-MS/MS and applying the various separation techniques to small molecules or proteins?

Instruments start at 250k and many in universities are decades older than what is currently used in industry. For small molecules, the most challenging (and exciting) library's of compounds are owned by third parties.

It is my opinion that science, much like programming, one has to do it to learn it. There are limitations to the knowledge you gain without being hands on. See E.O Wilsons musings of the impact his formative years and post grad school wanderings in the south pacific. He is certainly a scientist but much of his knowledge and insight is due to the hands on approach he used to to gain that knowledge.
For institutional investors, this is a very complicated question. There's always been ways that they are front-runed by more nimble traders.

Currently, the state-of-art for institutional investors are to use buy-side algorithmic tools to slice and dice their orders into 100 lots and obfuscate their huge lot order (> 100,000 shares). Algo's include iceberg which continuously monitors the quotebook throughout the day and execute a portion of customer's orders when the market turns in favor of direction of the order and with an order size not to disrupt the current momentum of the stock's price action; also special darkpools are used at mutual funds such as Liquidnet where no official quotebook are maintained, instead it's more of an instant messenger tool that is limited to only mutual fund managers who chit-chat and close large block deals. Any participants who are suspected of front-running are banned.

As for your original concern, yes spread of a few cents per share is very important for institutional investors when you have to execute a order for 100,000+ shares; and there's actually a whole technology vendor space in finance called transaction cost analysis that fund managers look at to see what the hidden cost of their trades are. As whether HFT actually help institutional investors, it's analogous to saying whether defense contractors help the federal government; some say it's symbiotic relationship, some say it's a parasitic relationship for all and symbiotic for some. Meaning most relationships on Wall Street like on Capital Hill, revolves around wine & dine & shifting allegiances. Quite a few HFT firms have tried to open a new line of revenue by opening up their high-speed infrastructure to institutions to execute their iceberg orders. Yet some of the HFT algorithms' intentions are to sniff out iceberg orders and front-run them.

The lack of libwget does frustate me sometimes; I have to use wget strictly via command-line. curl also has some nice features lacking in wget: selecting HTTP/1.0 or HTTP/1.1, support for multiple SSL libraries, etc. But wget surely has many features that curl doesn't have.

In short, I use both.

I didn't read the whole thing - it's not concise, that's for sure - but the general advice seems to be: Go find a lab job and see if you like it. Though his examples are specific to biology, I can't figure out what part of that advice is specific to biology. I did it in experimental physics and it worked out just fine.

Sure, the article is about about pursuing science rather than thinking about it. But that's the author's whole point. Enjoying a career is all about enjoying the day-to-day work: If you love thinking about DNA but don't love pipets, you're going to be unhappy a lot of the time, because life in the lab is about 10% deep thought and 90% pipets. (Or, in the semiconductor laser lab: 10% deep thought, 50% misaligned optics, and 40% mysterious process problems that you will never entirely understand, but which you will eventually solve by spending months on end turning knobs in a strategic manner.)
I think this 'problem' is already being solved pretty well by Tumblr and Pinterest. Tumblr is mainly used (by teenagers) to post images of things they think represent them (an activity that is very popular with teenages - the same reason they like to put up band posters in their bedrooms). I think Tumblr was meant to be a blogging platform, but this has become its main use. Pinterest can be seen as an extension of this but with more features (ability to group things rather than just having a single stream). I think a great deal of the success of Tumblr and Pinterest can be attributed to their extreme ease of use: to build up an online persona all you need to do is browse peoples' profiles and click 'reblog' or 'pin' - no need to even pull out your smartphone camera. My advice would be to make your app integrate well with these two services (offering an easy interface to upload photos from your phone) and try to slowly ween users from these services.
This comment demonstrated the fundamental point of your misunderstanding. Your ordering of events is not how it works. Eve doesn't "jump in the middle" What actually happens is this:

12:00:00.000 - Eve - BUY $10.00
12:00:00.000 - Eve - SELL $10.01
12:00:00.200 - Alice - SELL $10.00
12:00:00.300 - Bob - BUY $10.01

Eve was there before Alice & Bob. This is KEY to understanding what is going on here. Even is NOT jumping in the middle. Eve provided a service to both Alice & Bob and got paid for it.

Here's another way to think about it:

Alice wants the ability to sell her stock whenever she wants for a "correct" price. Right? That doesn't come for free. Someone has to figure out what the correct price is. That takes effort and costs money. Humans used to do this (they were called market makers). Now computers do it because they're better/faster/cheaper at it (just like they're better at a lot of things humans used to do).

They're also cheaper at it. The cost to Alice of getting to sell whenever she wants at a good/correct price has actually gone down from what it used to be. You can see this in the shrinking spreads. It used to be we only had price accuracy to a dime or a quarter. Now it's generally down to only a penny! Even though Eve is making money Alice is getting a way better deal than she used to before someone figured out how to program Eve to do it instead of the slow and expensive Harry the Human.

Enlighten me... a 1U server can handle nearly 1Gbps of traffic. BGP anycast - a solved problem. How many different locations do you need? For USA - Chicago, NYC, WashDC, Boston, LA, Phoenix, Dallas. In Europe - Amsterdam, Frankfurt, Berlin, London, Paris, Moscow/StPete, probably a few I have missed. Australia, Singapore, Taiwan, HongKong. Half a rack (20U) in each location would more than cover most, though possibly the USA would require more.

At the very least, this might be a sign that you should change your pricing structure so that future customers don't end up in that same unprofitable category.

You might also just consider it a cost of doing business. I've heard that Backblaze tolerates a certain number of unprofitable customers because it gains overall from having a single flat unlimited-usage plan.

How does vert.x compare to to Apache Deft?
It doesn't really matter.

For simplicity put SPDY on the edge and reverse proxy HTTP to whatever you used to use, this gets you 90% of the way there.

In the future, I expect we'll see tools like Mongrel2 take over. SPDY on one end, and some type of messaging on the other side. This will become more desirable with technologies like web-sockets that will stream data back. HTTP is simple, but hardly optimized for speed, even on a LAN. Thrift, Protobuffs, MessagePack, even Erlang's Binary Protocol (i.e. BERT) are all better fits for the internal RPC protocol

@fat and @douglascrockford, the HN community is now satirizing both of you. It's time for you both to do the right thing; add the semicolon to the bootstrap-dropdown.js code and change JSMin to support the original edge case.
Hopefully you change your employer more frequently than your spouse, hobbies, family, or friends. :)

The vast majority of people in the world do not have the luxury of loving their work. For those, 25% of their lives working for someone else in a job they tolerate but do not necessarily enjoy is a means to an end. Maybe it's 20 years of comfortable retirement, or the relative security of a regular paycheck to support their spouse and children.

Most of us on HN are lucky enough to enjoy coding and are well compensated for it. We get caught in the feedback loop of tech chatter and forget that the majority of our friends and family, outside the blissful tech world, do not enjoy their work.

> Fun challenge: try making a smalltalk app that isn't easily recognizable as a smalltalk app.

It is true that both Lisp and Smalltalk make it very easy for people to build things that would normally take a team and an architecture. This has the down side that if it's easy to build something that acts sort of like a button, that's what ships rather than bridging to some OS button. It's a lot of work to implement for no obvious benefit, especially to the Smalltalk programmer who is using the system because they like it and don't mind the differences. This seems like exactly the sort of thing that would make for-pay Smalltalk systems viable, but nobody seems to be willing to pay for a language now. Even if it would be cheaper in the long run, it's harder to do the math and it's hard to compete with free.

> I hope too there can be a "Clojure for smalltalk", if you will.

I think this is a concept that should be explored in more depth. Some things I'd toss out as worth discussing:

- Having a standard library or syntax for defining classes (GNU Smalltalk addresses this)

- Real namespacing, because I'm sick of seeing XXYYZZClassName

- Sexy, dirt-simple FFI to C or Java. Probably, as you point out, through a standard calling convention for external stuff (maybe borrow the Block API, something f value: a value: b value: c).

I think apart from these things you could really build the Smalltalk of tomorrow in the Smalltalk of today. You need really good OS integration, especially graphically but every other way as well. You probably need to be able to serialize the system to ordinary flat text files so you can use modern VC.

I know Juan Vuletich has been rebuilding the standard image his way from the ground up with Cuis but as far as I can tell progress is stalled. Other than that I don't know of any big project besides Pharo, which is even more modest, really just about removing crap from Squeak and producing a professional shame-free open source Smalltalk.

For a true start up I agree with you, they do not have the time. I am guessing this is what you mean by some companies?

For established companies with legacy code bases older than two years, there is always going to be a getting up to speed period. To pass smart people over because they chose the wrong buzz word for the focus of their last job (or the buzz words recently changed) is a great way to always have people that need to get up to speed on your team.
I don't think we're agreeing on the basic definitions, and until we do it's pointless to continue.

While I don't think it's what the reporter meant either, at least one bridge has been stolen before. http://old.post-gazette.com/pg/11280/1180364-455.stm#ixzz1a9...

I can't find the weight of that bridge directly, nor how they arrived at the value estimate, but if I'm reading it correctly, this (http://www.steelonthenet.com/commodity_prices.html) seems to say steel scrap was going for $428/ton in October 2011, so from the "estimated $100000" we can guess that it was about 234 tons of steel.

This is so true in programming as well. It's very easy to be consumed by the process and neglect the purpose and end-game.
Same here. One of my clients uses it for all of his sites, and we have all sorts of problems with it. For a while it was flagging my Linux and Mac PCs as sending viruses/spamming cloudflare sites. They couldn't provide me any logs though.

Announcing the release of Fedora 17 Beta
An IDE can't just parse the source code, it has to actually execute it find out what classes are defined.

There have been a few -- I think more than 3 -- Smalltalk projects where the parser was modified so that Class definition and other code could be executed but only result in a "shadow" Class being instantiated, so that the code could be browsed before being committed to the actual image.

only lets the programmer work with the runtime representation of the program, and not the on-disk representation. The whole ecosystem - language, libraries and tools - are designed around that paradigm.

It should be possible to have it both ways with Ruby. ObjectStudio Smalltalk had declarative class files. You don't want the runtime changes to be written back to the declarative files, however. This caused lots of problems in ObjectStudio. A better approach would be to have some way of flagging the runtime change, perhaps by outputting another file, then let the user merge changes back.

From the blog post.

I'd much rather see a Smalltalk that let me create small, headless images, tens or hundreds of kilobytes in size, with just the little bits of functionality I need for a particular task. If they had good libraries for file I/O, processing text on stdin/stdout and executing other commandline programs, they'd fill the "scripting language" niche very well. If they could be created and edited by a larger IDE image, they'd have the Smalltalk tools advantages as well.

Apparently someone at Digitalk did exactly this years ago, with images as small as 45kB. I think the project was called "Firewall." This technology will never see the light of day, but it shows what is possible.

Possibly. I looked at AIR briefly a while back, just before my lab transitioned away from Flash development, and while it does seem like it's on the right track, all I got out of it was that it's supposed to be used with ActionScript and runs JavaScript in an even more restricted security environment than browsers give you. Maybe it does do what I want if you strip away all the Flash junk obscuring it, I just haven't seen that demonstrated.

Aside from being interpreted rather than compiled, Microsoft's HTML Applications are really the closest thing I've seen to my Ultimate Vision, and I've actually used that platform to build major desktop applications.
