This site provides a free physics textbook that tells the story of how it became possible, after 2500 years of exploration, to answer such questions. The book is written for the curious: it is entertaining, surprising and challenging on every page.
...you should be cautious about including C hackers in your projects, as they are often the ones who have the most trouble adapting to the abstraction-based form of software development that object technology embodies... Bertrand Meyer
Our society is organized around a scarcity economy to such an extent that many people believe 'scarcity' and 'economy' mean the same thing. Even if it were true, different economies deal with differently scarce things.
Israel as being the United States’ “cop on the beat” in the Middle East. - Why do you hate America? - Have you ever been to a Wal-Mart? - immediate withdrawal? (Iraq)
In a room of just 23 people there’s a 50-50 chance of two people having the same birthday. In a room of 75 there’s a 99.9% chance of two people matching.
A single ant or bee isn't smart, but their colonies are. The study of swarm intelligence is providing insights that can help humans manage complex systems, from truck routing to military robots.
a C/C++ interpreter aimed at processing C/C++ scripts. Scripts are programs performing specific tasks. Generally execution time is not critical, but rapid development is. Using an interpreter the compile and link cycle is dramatically reduced facilitating
by Erik Demaine. Take a piece of paper, fold it into any flat origami, and make one complete straight cut (i.e., a cut along a line). Now unfold the pieces, and see what you get. Are all shapes possible? Refering back to the original sheet of paper, what patterns of cuts can be achieved by this process?
2.4GHz parabolic mesh dishes from Chinese cookware scoops & a USB WiFi adaptor! Called "WIFRY","WOKFI" or "WOKTENNA" (12"= 300mm diam) shows 12-15dB gain (enough for a LOS range extension to 3-5km)
by Alan Green - These checklists are a tool for helping you focus attention on the critical aspects of your project at the different stages of its lifecycle.
The NOVA mini-series The Elegant Universe, watch all three one hour episodes here, divided into chapters, available in the QuickTime or RealPlayer plug-ins.
is a layer above the existing toolkits available (Win32 API, GTK, Cocoa, ...). The result is that applications look and function like the user expects on their respective system. Mozilla Public License
explores a novel interface to a system administration task. Instead of creating an interface de novo for the task, the author modified a popular computer game, Doom, to perform useful work.
adaption of the H. G. Wells classic War of the Worlds in comic form by Ian Edgington and D'Israeli (merges 1800 version with some designs from the more recent movie)
open source animation, the Blender Foundation second open-movie project, a funny and furry 3D short about a giant rabbit who gets even with bullying rodents.
Weekend Project Podcast: Make simple radios to listen too. These were made with materials that they could get their hands on and were small enough to carry around in a big pocket.
by Jon "Hannibal" Stokes "I've been writing on CPU technology here at Ars for almost five years now, and during that time I've done my best to communicate computing concepts in as plain and accessible a manner as possible while still retaining some level
"In my opinion, good knife skills are an essential component of being a good cook. And good knife skills are not particularly difficult for the average person to learn."
projet universitaire réalisé à l'IUP informatique de Brest, features super-node, swarm, incomplete source downloads, MD5 indexing, and IP scans on startup.
the Gnutella network could and should be one of the core distribution tools on the Internet. We believe in open standards, open networks (sux, embrace and conquer)
"all of the techniques I know (and use) to reduce the size of executables. Some of these techniques can be applied to any C / C++ Win32 project, whilst other techniques are quite restrictive as to the type of application you can apply them to."
"we'd been finding the build getting slower and slower. The link phase in particular seemed to take an inordinately long time, much longer than our experience would indicate that it should."
Mac OS X, which combines a powerful core foundation with a compelling user interface called Aqua. With advanced features and an aesthetically refined use of color, transparency, and animation.
a high-level graphical application framework. Although Agar was initially developed as a game engine for the upcoming Trek to the Cave, it is also being used in different types of applications, such as CAD.
a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine 4 scripting
the XML C parser and toolkit developed for the Gnome project (but usable outside of the platform). Code is portable (to Linux, Unix, Windows, embedded systems, etc.) and modular; most of the extensions can be compiled out

Li Fan, Pei Cao and Jussara Almeida & Andrei Z. Broder - this new protocol, each proxy keeps a summary of the cache directory of each participating proxy, and checks these summaries for potential hits before sending any queries.
Why it is not replaced by COM, how it works, network DDE, links to other sources of information. DDE is support is being removed from Windows (Windows 7 x64 seems to have an issue with it)
"Only one third of a search engine is devoted to fulfilling search requests. The other two thirds are divided between crawling (sending a host of single-minded digital organisms out to gather information) and indexing (building data structures from the results)." By George Dyson
Vintage Japanese WWII Air Raid Defense Posters made in 1938, by the Japanese Red Cross working with government authorities to create a series of posters to teach the public about the new Anti-Aircraft Defense Law, which was enacted in seeming anticipation of air strikes following the outbreak of the Japan-China War (1937-1945).
turns VLC into a RAR player that allows you to watch videos (including seeking) directly from inside multi-volume RAR archives without the need to manually unpack them first.
Before you start working with photo images on your computer (or even view them), you should really make sure that your video subsystem is capable and is displaying things correctly. These pages will assist you in adjusting your monitor by providing various test patterns. They also give a brief introduction to issues involved in calibrating a monitor
aims to be for webservices and for C# programs what GNU/Linux is rapidly becoming for desktop and server applications: the industry leader and provider of Free Software solutions.
a general purpose monitoring platform. First, at run time, Pandora reads static configuration files either from disk or from the network. Second, if told so, Pandora opens a control socket to which commands can be sent. Pandora provides an API with C++, C and Guile bindings to ease the construction of clients. These commands allow queries of the actual configuration of the platform and to perform arbitrary modifications on it.
