The general idea is that your objects should model the program, not the domain.

Games may blur this line since they are simulations in some respect, which is a situation where you actually do want to model the domain. That doesn't mean you need anything as unsubtle as classes with a 1:1 correspondence to domain objects, though, which is what this article is about.
I've never understood why they use a stair step function for pricing. Why not just name a continuous function for pricing and simplify the scheme?
Just to confirm: even the Lean Launchpad site is now down http://www.launchpad-class.org/ I had been wondering when it would start since it was supposed to start this month.

Your points are all valid, and well-stated. In addition, I think there's a place for direct action with your buying power. Workers will continue to work under worse and worse conditions until consumers say "Stop--there's no justification for doing that, not even for profit!" If not now, will we still be buying products when a worker dies for every 10 units (of whatever) made? Every 5?

As it turns out, I have a petition, at http://www.change.org/petitions/tell-apple-you-wont-contribu.... This is not just a petition, but rather a boycott: to not buy Apple products until Apple increases vendor compliance to its "standards of worker conditions" audit by 11% (from 74% now to 85%).

Why Apple? Because Apple is trying to do better; because it's extremely visible; because it can afford to better than most companies; because so many people want its products; because changing Apple will be a tremendous start toward changing the rest of the electronics industry.

I really want a new iPod touch, but I signed this petition. Please consider signing. Please consider what it means not to sign. Thanks for listening.
1. The standard vesting arrangement is four years with a one-year cliff. This means 25% of your stock (as a founder) vests at the end of the first year, and the remainder vests month-to-month for the next three. In your scenario it sounds like the founders have been at it for two years before their first financing.

2. Why does the VC even have the right to fire the founders or CEO? The board has that right, and presumably the VC is on that board, but their rights are defined in the financing agreement. Control is an important negotiating point when raising a round of financing.

3. Why would a VC want to invest in a company where the founders have completely vested? What's to stop them from running off with the money, so to speak?

4. That said, I've seen incorporation documents where some small portion of the founders' stock is vested immediately (maybe 5%), and the remainder follows the standard four-year vesting, one-year cliff arrangement. This makes it a little harder to raise money and the VCs might insist on changing the vesting schedule as part of the financing agreement. Generally it's just easier to have everyone on the same vesting schedule, that way nobody can object.
It's funny how far we have come from working for the same company for all your life.

MongoDB is great at small scale. Basically, if everything fits in memory, it's awesome. If not, it slowly becomes a major pain in the butt, especially because of the global write lock.

I love all the concepts behind Mongo. Replication is so easy, and the data structure is extremely flexible. I just wish the implementation was as good. Hopefully one day...

The tools not working on other platforms isn't an Apple only problem, though. Visual Studio is Windows only, and unless I'm missing something, there are no good cross platform IDEs for C/C++ development. At least many of the underlying XCode tools uses are cross-platform (clang, git, ...). It's more than can be said for any MS dev tool.
But this is the problem. Most other industries do not operate with profits that allow for Wall St. salaries.
This is good news. Now if they would lower their EC2 instance pricing, especially large RAM instances!

> The problem with de-duplication is that it actually takes resources to do that.

Normalisation doesn't deduplicate by performing comparisons; it works by ensuring that there is one and only one logical place for the data to go. On OLTP tasks highly normalised databases as a rule perform better.

Where normalised data extracts its pound of flesh is in 1. join times and 2. the indices created to support reads and joins.

Yours is a case where, given the pattern of traffic, a highly denormalised data store makes sense. I just thought I'd explain to listeners-in why relational data stores can often do something with less total disk usage.

I have one, and it's OK -- you can notice broad differences with different activities or different mental states. The video game that comes with it is supposed to allow you to control a character, and that didn't work for me or other people who tried it at all. Also the plastic casing is really bad and broke quickly on mine. All in all neat but overpriced.
The problem is that outside of finance, it's very difficult to measure a programmer's productivity.

Actually what I was inferring is that between the rate of migration from older GNU tools to current BSD tools and the rate of response for security issues would combine to create a series of security failures in Mac OS. If that went on long enough and is publicized enough, it will effect iOS simply by guilt by association.

Certainly I have also noticed a slight improvement on the way Apple handles security problems but I don't really think it's an adequate response. More importantly I have the general impression that long term Apple is moving away from Mac OS & workstations and towards iOS & devices. So them ignoring Mac OS problems or becoming slower to react on them would not really surprise me... at least until people started to view iOS in an equally negative light because of it.

In any event, I honestly wish that Apple would maintain a larger presence in the FOSS community and put more effort into a more positive two way relationship.

a 1.5TB* Tape is about $50. However it: (1) should last longer than a HDD and (2) Uses much less power, cooling, floor space, etc.

* Tape also has really nice compression (essentially you would be using the on-tape compression at least 95% of the time) with an average of about 2:1 (and often much higher). But you can also compress files on disk -- so it's just native storage.

You're right. They seem to have disappeared. I recently received 2 very similar emails from two of the Stanford classes. Both emails stated that a tremendous amount of people have signed up for the class (over 50,000) but that the classes would be delayed in launching.

I'm curious if some of the delays in launch are to allow some of the instructors to hastily cobble together the textbooks that they are using for these classes. For example, the Stanford SAAS class starting this February is taking a "customer development" approach to the class textbook. The SAAS class is testing the textbook on a Berkeley class and then testing it on the 50,000 people signed up. But they aren't just "testing" it, they are selling it at a reduced rate ($9.99 on Kindle) for the early adopters who use the alpha electronic version in the class. They are also launching an iPad and print version. Such a brilliant way to craft an excellent book with user driven errata reporting and feedback while making a great profit on a first class of over 50,000 people. This free class business model is going to make a pretty penny. Here's a link to the SAAS book: http://beta.saasbook.info/
I really want this to work, but I'm skeptical. I've lived in India, and I know that corruption is rampant. These "middle men" will try hard to figure out another way to game this system. Hopefully it's the start of something, but I think the economist is being a bit too optimistic in claiming that this alone will transform India.
They're not developing a BSD-licensed shell because they already ship zsh.
I created this service to solve my own problems. Setting up system crons can get real annoying when you have multiple app servers.
Oh, no, I see that, I meant why don't they put the full text search engine (Lucene.NET, as per the comment below) on its own server. Wouldn't that make more sense, if they're running into this trouble?
I think they put development on hold (Nov 4 2011):

He's saying (I believe) that the only positive externality of HFT is a slight reduction in pricing errors. If the pricing errors were very large, then HFT would be providing a valuable service. The implication of the quarter versus dime metaphor is that the efficiency gain provided by HFT is very small.

However, my own study suggests the true situation is worse than he claims. Though HFT does appear to increase efficiency most of the time, it also creates sudden flares of inefficiency at the times when a well-functioning market is most needed.
Potentially memristors could lead to smartphones and tablets with the power of a server rack of today crammed into them, but also with improved battery life.

And that's one of the least revolutionary implications of memristor technology.
I really dislike the economist. To me the very first thing this program makes me think of is how the government will abuse it. They briefly mention that there is the possibility that some sort of privacy issue might pop up in the future, but quickly dismiss the argument as outweighed by the ends these means achieve. They even get a swipe in at 'market distorting subsidies' while their at it.

While other magazines might have bias the Economist takes it to a whole new level. I would call every piece of 'reporting' they do an editorial.

That said the article did prompt me to learn more. Top Google results which paint a slightly different picture.

A very well written article.

I've considered learning CoffeeScript but have decided for now to let things play out and focus on learning JavaScript better. There are a ton of frameworks for javascript (backbone/spine) that make it more bearable. Also JS for all its quirks is ridiculously powerful.

To me maintainability is huge in a project. There needs to be a really strong reason to choose CoffeeScript over plain javascript. Catching all syntax errors seems okay but not entirely justified. I usually catch those in a staging environment on a console.
They specifically want to economically encourage bringing the house with you to get the cheapest rate (total commitment); or encourage building a larger house than you might otherwise have. A continuous function of price reduction per unit, rewards everyone as they go; Amazon very specifically doesn't want to do that (users gain benefit at every step, and are rewarded just for being at any given metric, encouraging no particular scale or usage).

The price points are supposed to be mental carrots, in other words. It can of course be debated which approach is better, but I have to suspect Amazon has a lot of data on scaling and pricing from retail behavior.

No, the mistakes were made by the people setting up the rules of finance--government and society more broadly. Many financiers appear to have done quite well despite the crash. A large number lost their jobs, but they weren't the ones engineering the crash.
Yes! I currently have a server ran specifically for managing my cron tasks, I would love to outsource it to a reliable company. If you could guarantee reliability then I'd love to use it. Not sure about pricing though, but I'm paying $20/m for the server I rent (Linode) so if you could guarantee reliability and it meant I didn't have to manage anything myself I'd be happy to pay around that or more.
> Clearly - if you are paying 10s of thousands of dollars for a database server License, it makes sense to fully utilize the ones you've purchased.

I suspect this is the reason they're using a single server. It would cost a few more tens of thousands of dollars to install another one, versus the zero overhead of just upgrading the existing one.

As an OSS user, I often take for granted how easily I can go "Oh, the database reads are too slow? Let's throw another Postgres slave at it and see how that goes." After all, that expense is usually minimal.
There really isn't. I hope they do that.
This kind of thing has been open to Google "hacks" for a while now. It's also pretty simple to prevent. :/
I just mean that first you need to figure out how your engine is going to work -- what actual code you are going to write -- then go about organizing that code into an object model.

A physics engine will have classes for the things it cares about like masses, constraints, collisions, contacts, etc. A renderer could have things like meshes, materials, particle systems, and lights. Each subsystem has a different idea of what a particular vehicle, weapon, or monster is. Two monsters might have the same physics properties but be rendered very differently. A Koopa and a Flying Koopa might look the same but behave differently. You can't start with classes for vehicles, weapons and monsters, and expect these classes to be used across all subsystems.

OOP is really a way to organize your code. OOP doesn't generate solutions.
Particularly I'm thinking of the inescapable async-all-the-way down, which necessitates endless lambdas. In other languages it's possible to pick a point at which to invert control back to blocking-style; JS's single-thread model makes that impossible. So for instance all calls to the server API have to be callback style; if you have to make serial calls, you can't avoid nested callbacks.

I miss a set type, I miss solid iteration (although coffescript mitigates that), and immutable datatypes would be nice (I've got used to them in Clojure.) I miss a solid FP stdlib, although jQuery has map and filter, which goes a long way.

That's the ones I can immediately think of :).
I wonder how slow you'd be willing to go.

I wish this article was a joke. Anybody that has their parent's negotiate job benefits on their behalf probably lacks the self awareness to be ashamed.
I think you need to know things about both yourself and the company before you can make a decision like this.

Questions about yourself:
* Are you willing to sacrifice your free time and family time for your job?

* Can you get things done, even if it's not so clean?

* When crunch mode hits, how will you keep yourself centered? (e.g. exercise)

Questions about the company:

* What is the expected work schedule, and does it fit your life?

* How are they funded, do they have a revenue stream?

* What is the 1, 3, and 5 year plan for the company?

* Does your compensation include equity?

Hope this helps,

are these middle men serving as a buffer between large parts of the population and the government? i see both positives and negatives to such a relationship... one that has evolved over a long period of time.
There is tons to do even if the UID is successfully rolled out through out the country. First and foremost would be to get all government services to willingly accept the UID as the standard scheme ... I know that sounds ironic but such is the life in India ...
And much of the reason for those low profits is the high levels of debt that non-financial corporations take on.

Or in another way of analyzing the corporate world, if you track who owns the shares, you will find that almost everything is owned by a few large banks [1]. So in a sense, banking is the only activity that is profitable. This follows naturally from the structure of the economy -- capitalism [2].

As the author of a program/library, it just depends on what's important to you. If you want wide use of your code, a permissive license is the way to go. If you want to ensure your users offer the same freedom to users of their modifications that you gave them with the original, then a license like the GPL is the way to go. For you, it sounds like a license more permissive than the GPL would be appropriate. For others, I think a GPL-like license is a valid move.

When you're choosing a library or framework to build on top of, you pick the right tool for the job. Licensing is the same way, they're tools that have appropriate uses some of the time.

In a way, yes. It is an evolved relationship. Middlemen started out as traders who acted as the exchange mechanism, for example between farmer bodies and the consumers. Over time they have grown in strength and sadly in autonomy. Middlemen bodies exert huge influence over retail prices of goods in India.
