Most people here are assuming that Google will have the line items on your receipt. Credit card companies normally do NOT get that information. It takes extra work for the merchant to provide it. The top line data is both less intrusive and

I can't think of a better place that exemplifies this than Hacker Dojo in Mountain View.

I understand the industry quite well and from experience. BTW My only daggers were aimed at HFT. Let me be clear. Anybody that puts an order in not expecting to get executed but to create favorable conditions for their next order is engagin

Accurate article? Yes I think so. Hairsplitting? A bit. Any content about the big picture? Afraid not. Algo trading has been around longer than HFT. It was invented to protect the information that that a big order was being executed. This a

Just to clarify for the crowd, portfolio theory, at least as far as its connection to linear algebra, is the mathematics of a covariance matrix. You are talking about different ways to decompose such a matrix. There are many ways and the ju

I used Jim Hefferon's Linear Algebra to get back into the subject a few years ago. Great balance of rigorous and intuitive. Free book available here http://joshua.smcvt.edu/linalg.html/

Great job making the font size respond to Cmd+. Many sites seem to drop the ball on this important feature (ahem LinkedIn, NYTimes mobile).

Nah. Adhominaters gonna adhominate. Facts reduce the (net) number of things to argue about. Anonymous lets the commenter create a straw man or label the author as fanboi even more easily.

Folks, this article is about private equity. 10 to 1 odds it doesn't apply to you. Not tips for dealing with VCs. Interesting if you like finance.

The Maybe and Either type classes are typically used to model exceptions in Haskell.

The main thing a statically typed pure functional language tries to do is force you to "mark" the side effect in your code with type annotations. Various effects can be modeled with different types. Many of these types still support some fo

Do absolutely nothing. Move on. It's like an auto accident. Plenty of reasons to feel anger. No reasons to act on those feelings.

Thanks and sorry--I misrecollected. The correct title is Probability Theory: The Logic of Science.

If you find the conflict around frequentist and bayesian methods entertaining check out Jaynes' Theory of Probability, which profiles lots of great arguments and personality profiles. Also you might learn a few things about maxent, statisti

Yes there is a great deal of irony in standard business practices. No irony intended.

Volunteerism doesn't work when there is too much money at stake. How much has that green consumer really done for the environment without assistance from a carbon tax? Like calls for conservation, this is well-intended, but a distraction fr

It's not a bad way to discriminate between people based on how much they think about technology. The less informed only see the term when it appears in a bad news headline. Others know there is more that one meaning. At Hacker Dojo we have

No mention of annoying customers with emails. The notion of marketing as pestering needs revision.

Ok. Fewer run time errors = fewer tests. Also check out QuickCheck for automatically generating tests. It's very handy.

by T_S_ 15y ago
Think of it this way. More compile time errors = fewer run-time errors. You can still have bugs of course. Most my Haskell run-time bugs are because I defined a partial function. Many standard functions are partial too. I find that changing

Truly useful features require truly useful data to support them. Many devs are incredibly creative at using the data at hand in innovative and even beautiful ways. The Swiss Army knife syndrome, which I have seen in shopping apps, comes fro

I used to design financial products. The New York sales person would usually say "My customer will not buy that piece of s&#t." The Tokyo salesman would say. "I will show it to my customer." Then radio silence for a week. Or at worst,
