Why removing the uncertainty principle accidentally creates perpetual motion I think some of the best examples of this come from the Quantum Mechanics-Thermodynamics interface. For example, if you try to compute entropy in Statistical Mechanics (basically mathematically formal Thermo) from first principles, you get a nonsensical answer... until you include the idea of indistinguishable particles, and then you get the right answer! So Stat Mech "knows" about fermions being indistinguishable (and hence the Pauli exclusion principle) without any input from you!
Signs that you're a bad programmer - Software Engineering Tips Why was this written? Most of these faults were discovered the hard way by the author himself, either because he committed them himself or saw them in the work of others. This paper is not meant for grading programmers, it was intended to be read by programmers who trust their ability to judge when something is a sign of bad practice, and when it's a consequence of special circumstances. How To Become A Hacker Copyright © 2001 Eric S. Raymond As editor of the Jargon File and author of a few other well-known documents of similar nature, I often get email requests from enthusiastic network newbies asking (in effect) "how can I learn to be a wizardly hacker?". Back in 1996 I noticed that there didn't seem to be any other FAQs or web documents that addressed this vital question, so I started this one.
How to hide files in JPEG pictures If you’re looking to hide files on your PC hard drive, you may have read about ways to encrypt folders or change the attributes on a file so that they cannot be accessed by prying eyes. However, a lot of times hiding files or folders in that way requires that you install some sort of software on your computer, which could then be spotted by someone else. I’ve actually written quite a few articles on how you can hide files and folders in Windows XP and Vista before, but here I’m going to show you a new way to hide files that is very counter-intuitive and therefore pretty safe! Using a simple trick in Windows, you can actually hide a file inside of the JPG picture file! You can actually hide any type of file inside of an image file, including txt, exe, mp3, avi, or whatever else. Not only that, you can actually store many files inside of single JPG file, not just one!
Password crackers SecTools.Org: Top 125 Network Security Tools For more than a decade, the Nmap Project has been cataloguing the network security community's favorite tools. In 2011 this site became much more dynamic, offering ratings, reviews, searching, sorting, and a new tool suggestion form . Close To The Machine Close to the Machine: Technophilia and Its Discontents, EllenUllman, City Lights Books, 1997. (ISBN 0872863328 ) "The world as humans understand it and the world as it must be explained to computers come together in the programmer in a strange state of disjunction." (p.21) "Soon the programmer has no choice but to retreat into some private interior space, closer to the machine, where things can be accomplished." (p.23) "The corollary of constant change is ignorance. This is not often talked about: we computer experts barely know what we're doing. We're good at fusing and figuring out.
What every computer science major should know Portfolio versus resume Having emerged from engineering and mathematics, computer science programs take a resume-based approach to hiring off their graduates. A resume says nothing of a programmer's ability. Every computer science major should build a portfolio. 70 Things Every Computer Geek Should Know. The term ‘geek’, once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field. A geek is one who isn’t satisfied knowing only the surface facts, but instead has a visceral desire to learn everything possible about a particular subject. A techie geek is usually one who knows a little about everything, and is thus the person family and friends turn to whenever they have a question.
Cain & Abel Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, recovering wireless network keys, revealing password boxes, uncovering cached passwords and analyzing routing protocols. The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort.
Short Film of the Day: Stuxnet: Anatomy of a Computer Virus Why Watch? Because we should challenge how we define a film. Most of the shorts featured in this column are either easy to spot as stories or completely experimental. Even when a documentary short is in the spotlight, it tells a clear tale of people doing things. Lorentz transformation In physics, the Lorentz transformation (or transformations) is named after the Dutch physicist Hendrik Lorentz. It was the result of attempts by Lorentz and others to explain how the speed of light was observed to be independent of the reference frame, and to understand the symmetries of the laws of electromagnetism. The Lorentz transformation is in accordance with special relativity, but was derived before special relativity. The transformations describe how measurements of space and time by two observers are related.
Humor - How to Shoot Yourself In the Foot Using Any Programming Language The proliferation of modern programming languages (all of which seem to have stolen countless features from one another) sometimes makes it difficult to remember what language you're currently using. This guide is offered as a public service to help programmers who find themselves in such dilemmas. 370 JCL You send your foot down to MIS with a 4000-page document explaining how you want it to be shot. Three years later, your foot comes back deep-fried.
