The Ultimate IT People Test

Below is a list of 800+ names of influential IT, Com Sci, and computer related people. There are Linux gods, Microsoft gurus, famous scientists, notorious hackers, game designers, authors, entrepreneurs, and more. How many do you know? Go ahead and test yourself.

For each name:

1. If you recognize the name give yourself 1 point.

2. Give yourself another point if you know an approximate date of birth.

3. Finally, a further 3 points for identifying what that person is famous for.

Underneath the list is a set of links to help you find the answers. You'll have to do a little bit of research, but you wouldn't be doing a geeky test like this unless you enjoy that kind of thing... would you? :) * Update - I've removed some duplicates and marked those numbers with DUPLICATE REMOVED.

C# Interview Questions

The ability to do something does not imply that you can explain it conceptually, or even that you understand the concept of what you are doing. So I have prepared a list of questions\tasks that I think would be useful to complete before going for a C# related job. I have also provided a separate page with questions AND answers for the first set of 173 questions, and another page for the answers to the rest of the questions (not including Scott's questions). You can find the first link below the first set of questions and the second link at the bottom of the post - they are also directly below if you want to jump straight to them.

1+1=3

On the subject of emergence.

Emergent properties (http://en.wikipedia.org/wiki/Emergence) of collections of smaller "things" seem to be very real physical properties. By saying a property is emergent we are saying that its parts cannot fully explain that property. It seems that, as though "by magic" these emergent properties appear when systems get complex, and large enough. The trouble is, even though they are real there is no overall classification system for them (like that of fundamental particles). So why not make one?

Let's have a crack at it. first off we need a model and some rules.

Confused? Me too, here's an example:

First off, pure reductionism (no emergent properties). Let's count the number of particles in this system (we'll try it with a universe containing 5 A) .

1 AAAAA

2 AAAAA

3 AAAAA

4 AAAAA

5 AAAAA

Size does NOT matter in this universe, if you used a microscope to peer down through the scales you would see at size 1 the 5 instances of A. As we get larger (2 and up) the 5 particles still totally describe the universe and nothing new happens (is emergent). No molecules with new properties, no vortexes, no human consciousness, etc. - just cold, hard, boring particles. The number of things in this universe is 5.

Now let's add in some rules of emergence.

1 AAAAA

2 (AA)(AA)A

3 (AAA)AA

4 (AAAA)A

5 (AAAAA)

At size 2 for example, size does matter - we have 2 new B particles (AA) and (AA). Following this logic further you can see we have an (AAA) particle, which could be called C. Then (AAAA) = D and (AAAAA) = E. When we replace sets of A with other letters we get:

1 AAAAA

2 BBA

3 CAA

4 DA

5 E


The list of all things here is (A,A,A,A,A,B,B,C,D,E) which is 10 entities. The number of things can be counted by using a basic formula:

# of things = sum[i=1,...,n] (floor(n/i))

So we can loosely say that 2A = 3 things (an A, another A, and a B) so, roughly speaking, 1+1=3.

So what's this good for?

The classification and categorisation of emergent properties is adhoc. What if there is a pattern in the REAL WORLD by which we can classify and possibly even predict emergent properties?

Something to think about...
