i work on a quantitative trading desk at one of the big investment banks and i get quite a unique opportunity to straddle both the tech world and the finance world. most trading and risk mgmt systems are built using Java or C++ in linux environments...
in my world I rely heavily on perl and python. R or Matlab are good tools for doing regressions. R is FOSS. Matlab is not so we end up paying for a few licenses. In return you get good customer service, regular updates and a nice set of toolboxes for doing things like GARCH, etc..
Now you gotta ask yourself what sort of trading are you going to be doing? Are you looking at day-trading? This entails looking at market order books - bid/ask quotes and trades and working with large datasets. At this pt you may want to start thinking about optimizing your calculations and managing memory. A full days worth of quotes in today's market can be up to 60GB uncompressed (obviously this depends heavily on the formatting, etc... - but thats sorta what you have to deal with). You're better off writing optimized routines in something fast like C++. Pushing that much data through R or Matlab will grind those tools down to a halt.
Getting your hands on "tick" data is not too cheap if you're an individual. You can look up TAQ data on the NYSE website. They charge about $1000/month for access to their tick data.
If you're looking at investing (rather than just trading) on a longer time-horizon. Then you're going to need fundamental data. There are plenty of companies that charge hedge funds, etc millions of dollars a year for this type of data - companies like Bloomberg, Factset, Barra, etc... The thing is most fundamental data is freely available in regularly filed reports with the SEC - like 10Ks and !0Qs. What you are paying for is getting this data in 1 place and ensuring its quality which is crucial.
How did you move from the computer science to the VC world? What is the ideal way to make the transition from a highly technical environment to one that is more about business and management.
I dont get this 3 cars on a quarter thing. Whats the point of using such an analogy? Would the force change if 3 cars were piled onto a surface that was 1 square meter - no....
Actually, I've heard that they've changed the MAC address restriction here at CMU. If you try to get on the wireless network you will be assinged an IP but are restricted to the homepage... or something like that. If you try to access an outside site you'll be asked to type in ur username...
Ever heard of a balun? This is one of the stupidest ideas I've seen. Basically, where I go to school (CMU), you can't plug in your RJ-45 ethernet cable into the wall without using this special balun adapter. Seems like some proprietary IBM design. Can anyone clarify this?

I went to CMU and the drama students are the *last* people I'd go to if I wanted to teach a robot to act "human."
I still go to CMU and agree whole heartedly with that fact.
Thats actually not true... Some European companies have actually managed to do handover between GPRS and WLAN and vice versa. (Quick google search reveals this. Its possible and is definitely one of the next big things...
Apparently the poor Asus site has already been slashdotted!
I've been a longtime PC user, I run a dualboot with Linux and Windows. Right now, I am also currently searching for a new laptop and Apple seems to have caught my eye, especially with those new Titaniums and OS X.
So, what are the arguments against switching over to Mac? I mean, the hardware is sleek and sexy... 15 inch screen with slot-loading DVD can play for about 4+ hours on a single charge. And now with Darwin, you get more UNIX compatibility. Plus, Apple only sells supercomputers! In addition, you can get 20% off any Apple hardware bought from their site if you get a $99 student membership. What reasons should I have not to convert?
WOW, I've just checked out your posting history. Of the 50 or so comments you've posted, NONE are above -1. You should go down in the Slahsdot Book of Records... Congrats
I have a SONY PCV L640, the slimtop design that comes with a proprietary LCD screen. Anyway, I've installed RH7.1 and now want to run X but can't get the right settings. The integrated video adapter is an ATi Rage 128 Pro 4XL. I've searched the net for this. Anybody has any idea how to get XFree86 running? (The problem is not with the screen, im sure).
For people who came after the/. effect, here is the text of how they made their server:
With names like Western Family, Realistic, Tandy and TDK; humanclock.com's middle-management attempts to cut every corner possible when it comes to industrial-strength webhosting. Many web hosting companies use expensive servers with complex software for their web operations. Our engineering staff rewrote the popular Apache webserver software to run on an 18 year-old portable computer with 32k of memory.
Humanclock.com runs on a Radio Shack 2.4mhz TRS-80 Model 100 portable computer, using a stripped-down version of the Apache webserver software (version 100-BASIC.12 beta). The graphic files are stored on magnetic tape accessed via a modified Radio Shack personal cassette player (CAT NO. 14-1215). The webserver is powered by a 6 volt TRS-80 AC Adaptor (CAT NO. 26-3804). We take our web hosting very seriously at humanclock.com, therefore we have installed 4 "AA" batteries in the webserver in case of power failure. Whereas some battery backup systems last for only 20 minutes and cost hundreds of dollars, our power backup solution lasts for 20 hours and costs $2.49, (due to it being double coupon Tuesday). In the case of power outage however, it takes our webserver about one second to come back online, something that would take a common UNIX/NT system over two minutes.
Apache software in action We hired a crack team of crafty crack monkeys that were able to modify the Apache source code and reduce it down to a 25k text file that runs under the BASIC interpreter native to the Tandy TRS-80 Model 100. Those were some smart monkeys.
Our engineering department was able to rewire this ordinary personal cassette player (not to be confused with a "walkman"), to handle the vast storage needs that humanclock.com requires.
All I/O is performed through the headphone jack.
The storage media consists of a single TDK type I cassette tape. The "Rigid-Construction cassette mechanism" gave our IT deparment an overwhelming sense that it was 65 cents well spent. We estimate that roughtly 4 gigabytes of data can be stored before we have to turn over the cassette and record over the side labeled "Kick ass Toto mix tape".
WOW, can you really do that?!?! How many users can it support during a certain time frame?
I gotta make myself one of those!
Wonder if anybody has any links about incredible web servers like this one?!?
I've been to the MIT Flea a couple of times. There's tons of interesting stuff you can buy (eg: I got a mini-CDR - 41 megs! I figured I'd put a bootable Linux on it and stick it in my wallet). The problem is it takes a lot of time to sift through the junk. What every vendor should do is compile a list of everything they have to sell and stick it in a database. The buyer can just search for what he needs and then head over to the corresponding booth. Good idea, huh?
BTW: Anybody heard of something like this in the Pittsburgh area?
I've become intrigued by all this CD corruption and decided to get a better look at it myself. So I've been looking for Philip's Red Book standard for CD-DA and the best link i got was this Philips site. To download the documentation you need to be a licensed company. Anyone has ideas for where to look?
Java is a great language and should, without any doubt, be taught early on in a computer engineer/scientist's education. As an introductory course, however, Java is an overkill. When introducing a student into the world of computer programming, one must bear in mind that there is a huge learning curve the student must overcome. Half the stuff you encounter in a "Hello world" Java program isn't fully explained until a couple chapters later.
The best introductory language is Python. Python provides a beautiful object oriented programming environment. To begin, a "hello world" program consists of one line: print "Hello World" as opposed to Java:
public class HelloWorld{
public static void main(String args[]){
System.out.println("Hello World");
}
}
Python does not use semicolons or brackets to group bodies. Instead, it relies on indentation. Such good programming practices can be carried over when prorgramming in other languages. Python's extensive module libraby helps introduduce students early in the learning phase about file input and output, string manipulation, regular expressions, and networking. Let's not forget about Python's graphical interface through Tkinter.
Python, it must be noted, is not a compiled language like Java or C. It is interpreted. As a result, the student can run code straight through the Python command interpretor. (Python is also a great scripting language) True, this postpones the details of compilers and memory management until other languages are taught but in the end it is introductory programming that you want to teach. Python provides the student with a strong foundation in the essential structure of a programming language.
I have the same VAIO desktop computer and experienced the same problems while trying to install Linux. The problem is not with the flat panel screen since I tried configuring X with a standard CRT screen. The same results appeared. I dont believe that this computer uses a NeoMajic chipset either. I think thats only for VAIO laptops.

I don'r agree, I believe credit is due to the people who are at the forefront of developing open-source software. Support open-source all you can!

Have I missed something or did u just mean 3G?
What kind of advice is that? History is for those who live in the past... What use does that have?
