TCP/IP , or Transmission Control protocol/Internet Protocol, is literally the backbone of internet and network communication. The concepts of TCP/IP are difficult to grasp without previous experience, so don’t be dismayed if it doesn’t click instantly. To better help you out, we’ll start from the very beginning- with a definition of just what a network is. Networks, Protocols, and Suites, Oh My! A is simply a collection of computers or similar devices that can communicate over a transmission medium.
Computer science is an interesting field to go into. There are a number of opportunities in computer science that you can take advantage of. With computers increasingly becoming a regular part of life, those who can work with computers have good opportunities.
Let me open with a disclaimer. What follows is an unabashedly opinionated diatribe certain to offend many programmers. Craftsmen inevitably grow defensive of their favourite tools and practices. Rather than respect this natural sensitivity, I will exploit it, shamelessly intensifying the vitriol for attention. I care little whether one applauds or deplores my views; I mainly want my audience to feel compelled to read on. However, I try to be informative as well as incendiary.
A good programmer is someone who looks both ways before crossing a one-way street. -- Doug Linder, systems administrator A most important, but also most elusive, aspect of any tool is its influence on the habits of those who train themselves in its use. If the tool is a programming language this influence is, whether we like it or not, an influence on our thinking habits. -- Edsger Dijkstra, computer scientist Being abstract is something profoundly different from being vague... The purpose of abstraction is not to be vague, but to create a new semantic level in which one can be absolutely precise. -- Edsger Dijkstra
I’m busy tidying up a few loose ends with work at the moment, before family arrive for Xmas – and I just haven’t have any time for in-depth articles. So instead of my own words, here’s a few of my favourites from other people: “Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.” - Brian Kernighan
The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)by Joel Spolsky Wednesday, October 08, 2003 Ever wonder about that mysterious Content-Type tag? You know, the one you're supposed to put in HTML and you never quite know what it should be?
C is the desert island language. This is my favourite statement from a talk Rob Pike gave in 2001 . Despite its age, despite many flaws, C is still the de facto standard, the lingua franca. Why? As with other older languages, inertia is partly to blame, but this cannot be the only reason.
Have you ever read through a chapter in one of those Learn Such and Such in 21 Seconds books and realized that somewhere along the way you had started daydreaming about how you would spend a trillion dollars if you were Bill Gates? Well, it happens to me all the time. Computer books are boring. In fact, most technical writing out there bites the big one and there's no sign that the situation is going to get any better in the near future. The really unfortunate thing about this predicament is that now, more than any other period in the history of computing, is when we really need good, clear writing out there. Whether the established priesthood of computer science likes it or not, the web has opened the flood gates and computer science is being secularized post haste.
For new computer science students, the concept of recursive programming is often difficult. Recursive thinking is difficult because it almost seems like circular reasoning. It's also not an intuitive process; when we give instructions to other people, we rarely direct them recursively. For those of you who are new to computer programming, here's a simple definition of recursion: Recursion occurs when a function calls itself directly or indirectly. A classic example of recursion The classic example of recursive programming involves computing factorials.
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. A lot of hackers now consider it definitive, and I suppose that means it is. Still, I don't claim to be the exclusive authority on this topic; if you don't like what you read here, write your own.
View Computer Musings, lectures given by Donald E. Knuth, Professor Emeritus of the Art of Computer Programming at Stanford University. The Stanford Center for Professional Development has digitized more than one hundred tapes of Knuth's musings, lectures, and selected classes and posted them online. These archived tapes resonate with not only his thoughts, but with insights from students, audience members, and other luminaries in mathematics and computer science. They are available to the public free of charge. "I have always liked the concept of universities as they were in Ancient Greece, where folks who had something cool to say would just come and say it.
