Everything you need to know about buying a camera 184inShare Jump To Close By David Pierce and Vlad Savov Cameras are everywhere. Camera companies don’t exactly make life easy, either. Sticky TOC engaged! A guide to this guide As with our smartphone buyer’s guide, you should be careful not to treat this as a definitive dictum on what to buy. Basics of photography Basics of photography Every camera, from the tiny webcam embedded in your laptop to the full-frame pro cameras built by Nikon and Canon, operates under the same set of basic principles. The most common technique for making this recording is by channelling light through a lens onto a photosensitive material that soaks it up and turns it into an image. Since light is the only information your camera collects, it should come as no surprise that well-lit scenes typically come out looking sharper and nicer than dark and moody shots illuminated only by a streetlight — more light just gives you more information to work with.

The Internet Guide to Jazz Age Slang Below you will find an alphabetical listing of slang words used in the "Jazz Age" (generally taken to mean the years of the Roaring Twenties and the Great Depression). The Jazz Age was the first modern era to emphasize youth culture over the tastes of the older generations; the flapper sub-culture had a tremendous influence on main stream America--many new words and phrases were coined by these liberated women. These are the most common words and phrases of the time, many of which you may be surprised to note are still very much in use today! Some entries were the exclusive domain of students (or rather, those of student age; only a very small percentage of the population attended college) or flappers and have been indicated as such with italicized monikers. Also, the words that emerged in a particular year are noted appropriately. Note: the majority of the entries were gleaned from a great slang dictionary called Flappers 2 Rappers, written by Tom Dalzell (Merriam-Webster, 1996).
The Python Tutorial Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms. The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, and may be freely distributed. The Python interpreter is easily extended with new functions and data types implemented in C or C++ (or other languages callable from C). This tutorial introduces the reader informally to the basic concepts and features of the Python language and system. For a description of standard objects and modules, see The Python Standard Library. The Glossary is also worth going through.
Electrical Engineering and Computer Science | 6.00 Introduction to Computer Science and Programming, Fall 2008 | Video Lectures RunSnakeRun Python (c)Profile Viewer RunSnakeRun is a small GUI utility that allows you to view (Python) cProfile or Profile profiler dumps in a sortable GUI view. It allows you to explore the profiler information using a "square map" visualization or sortable tables of data. It also (experimentally) allows you to view the output of the Meliae "memory analysis" tool using the same basic visualisations. Features RunSnakeRun is a simple program, it doesn't provide all the bells-and-whistles of a program like KCacheGrind, it's intended to allow for profiling your Python programs, and just your Python programs. For Meliae memory-dump viewing, it provides: sortable data-grid views squaremap of memory-usage basic navigation Installation You will need to have all of wxPython, SquareMap and RunSnakeRun installed to use RunSnakeRun. apt-get install python-profiler python-wxgtk2.8 python-setuptools virtualenv runsnakesource runsnake/bin/activate easy_install SquareMap RunSnakeRun Usage If you are new to profiling you may wish to check out:
Aug 4, 2011 Misquoting me makes you sound stupid. So does taking what I say out of context, putting words in my mouth, and drawing false conclusions based on things I've said. That out of the way, I keep seeing the same poor, tired arguments and examples repeated over and over around the Internet. Here are some outright falsehoods that continue to perpetuate. Ebooks hurt the eyes. E-ink technology is passive, just like staring at a piece of paper. I'll never give up print books because I love them too much.It's always painful to embrace a new technology. There have been too many success stories of people without built-in platforms. So much self-pubbed crap will be published, you won't be able to find the good stuff. Debunked that here. Low prices devalue books. The value of a book is how much money it earns, not its cover price. You can't publish something of quality without a publisher. Too many examples say otherwise. Konrath is a hypocrite who once said self-pub is bad. Self-pubbed books aren't edited.
