In theory there is no difference betweem theory and practice, but in practice there is. I agree that in default should works the way you say, but that is theory, in practice it is not what actually happens a the OP found out. And we need to

This is funny. So there are people in this world that do not live up to your standards and react with self-righteousness (btw. <sarcasm>shocking</sarcasm>) and you suggest the right way to respond to it. Isn't that self-righ

I wonder... Does the original website from which the photo was taken had: 1. A statement that the photo was not public domain? 2. A way to contact the author with the clear purpose of license it? I can understand that someone might react ag

You are focus in the wrong question. His advice is like saying: you are good at tables and divs, pick one and be great. Design and front end goes hand in hand, is really hard to be excellent on one and sucky at the other. His advice refelec

Not really. You can use an ITIN. IRS gives them and they are for tax tracking only. http://www.irs.gov/individuals/article/0,,id=222209,00.html With that and a passport you can easily walk into a bank and open a checking account.

"I speak with an accent, I don't think with an accent" (bonus points for knowing the movie reference). Grammatically correct phrases are proof of mastering the language, not of IQ. Specially if English is not your mother tongue.

Actually I am observing this news... and how the licencing for SQL Server will end up panning out. Some people here still thinks that row oriented databases can compete in aggregation speed, so if I do a MVP it will require a lot of teachin

Yes, the only problem I found when writing my own bitmap index is they become cumbersome when asking the question: what value has this column for this row. RLE does not help there. But they are extremely fast when asking the question: what

But column orientation is not at all about normalization, it is about data structures and manipulating it.

In the US prios art does not count anymore. There are papers since the 60s about bitmap indices, but now is first to file not first to invent... Politics screw us up again

Not accurate, you don't need to get all the columns, actually you don't need to operate over all the values of the column. If the data oes not change frequently, then column oriented is faster. The trade off is how many structures needed to

The difference is in the operations. With a b tree the software operates on 1 row at a time, but when represented as a series of bit, then in a 32 bit CPU you can process 32 rows in 1 instruction. Which leads to bitmap index over GPU...

For a project where I needed to quickly partition a data tale of millions of rows at multiple levels, I wrote a column database with bitmap index for data storage. It is 100% c# code. The queries and data manipulation is lighting fast the d

The problem... Models are brittle. If they are, then they are not complete enough.

Pressed reply instead of the word correction. Calculus should change the way you understand and perceive the world around, if it didn't, either you got bad teachers and need to ask for your money back, or you were studying only for the test

Ok. Javascript. It is closer to functional programming than to object oriented. But most developers don't see this and believe that since they can get by shoehorning "classes" into a prototype then they are back to what is familiar. Prototy

Correct. This does not oppose my original statement. Math is not just arithmetic or geometry. Is also a way of thinking and a way to sort and structure your analysis. Which helps you to know how to use psychology to ask the right questions,

I disagree. Generally I see this problem when trying to program in a functional languaged with an imperative thinking. This is not a weakness of the language, but of the developer. I think the hunch of the original article is that few progr

Most programmers know about SQL statements... But rarely identify it with set theory and that difference has a big impact on how you design and program databases. Being able to get by without that understanding is no excuse.

I find funny how people want languages to be "friendlier" It is often an egocentric excuse to not lean new tools... As if programming was about making he programmer comfortable, as opposed to producing the best result possible.
