wxWidgets: Cross-Platform Development Tips
Saved by uncleflo on April 10th, 2021.
This chapter describes some general tips related to cross-platform development. The main include file is "wx/wx.h"; this includes the most commonly used modules of wxWidgets. The file "wx/wxprec.h" includes "wx/wx.h". Although this incantation may seem quirky, it is in fact the end result of a lot of experimentation, and several Windows compilers to use precompilation which is largely automatic for compilers with necessary support. Currently it is used for Visual C++ (including embedded Visual C++), Borland C++, Open Watcom C++, Digital Mars C++ and newer versions of GCC. Some compilers might need extra work from the application developer to set the build environment up as necessary for the support.

www.crockford.com - jsmin.c
Saved by uncleflo on April 12th, 2018.
JSMin is a filter which removes comments and unnecessary whitespace from JavaScript files. It typically reduces filesize by half, resulting in faster downloads. It also encourages a more expressive programming style because it eliminates the download cost of clean, literate self-documentation. What JSMin Does: JSMin is a filter that omits or modifies some characters. This does not change the behavior of the program that it is minifying. The result may be harder to debug. It will definitely be harder to read. JSMin first replaces carriage returns ('\r') with linefeeds ('\n'). It replaces all other control characters (including tab) with spaces. It replaces comments in the // form with linefeeds. It replaces comments in the /* */ form with spaces. All runs of spaces are replaced with a single space. All runs of linefeeds are replaced with a single linefeed.

Brian’s 10 Rules for how to write cross-platform code
Saved by uncleflo on July 19th, 2016.
I’ve had a lot of success in my 20 year software engineering career with developing cross platform ‘C’ and ‘C++’ code. At Backblaze, we just released the Mac beta version of our online backup service, so I thought it an apt time to discuss my 10 rules for writing cross-platform code. We develop an online backup product where a small desktop component (running on either Windows or Macintosh) encrypts and then transmits users’ files across the internet to our datacenters (running Linux.) We use the same ‘C’ and ‘C++’ libraries on Windows, Mac, and Linux interchangeably. I estimate it slows down software development by about 5 percent overall to support all three platforms. However, I run into other developers or software managers who mistakenly think cross platform code is difficult, or might double or triple the development schedules. This misconception is based on their bad experiences with badly run porting efforts. So this article is to quickly outline the 10 simple rules I live by to achieve efficient cross platform code development.

CATIA - Wikipedia, the free encyclopedia
Saved by uncleflo on July 15th, 2014.
CATIA (Computer Aided Three-dimensional Interactive Application) is a multi-platform CAD/CAM/CAE commercial software suite developed by the French company Dassault Systèmes directed by Bernard Charlès. Written in the C++ programming language, CATIA is the cornerstone of the Dassault Systèmes software suite. CATIA started as an in-house development in 1977 by French aircraft manufacturer Avions Marcel Dassault, at that time customer of the CAD/CAM CAD software to develop Dassault's Mirage fighter jet. It was later adopted in the aerospace, automotive, shipbuilding, and other industries.

Independent JPEG Group
Saved by uncleflo on February 14th, 2012.
IJG is an informal group that writes and distributes a widely used free library for JPEG image compression. The first version was released on 7-Oct-1991. The current version is release 8d of 15-Jan-2012. This is a stable and solid foundation for many application's JPEG support. You can find our code and some supporting documentation in the directory files. There is a Unix format package in tar.gz archive format jpegsrc.v8d.tar.gz and a Windows format package in zip archive format jpegsr8d.zip. To learn more about how to use JPEG, see the JPEG FAQ. If you'd like to learn about how JPEG works, start with the comp.compression FAQ. The ISO/IEC JTC1/SC29/WG1 standards committee (also known as JPEG, together with ITU-T SG16) has their own web site. IJG is not affiliated with the ISO committee. IJG development continues. Advanced features are being prepared for coming releases...

Moreover, Professor Randal Bryant, the Dean of Computer Science at Carnegie Mellon University, has personally tested almost everything with his Uclid code verification system. What he hasn't tested, I have checked against all possible inputs on a 32-bit machine. To the first person to inform me of a legitimate bug in the code, I'll pay a bounty of US$10 (by check or Paypal).

Optimizing Your C/C++ Applications, Part 2
Saved by uncleflo on August 17th, 2011.
In high school, we learned that some mathematical operations are logically equivalent, as well as rules for transforming operations into easier-to-solve formats. But as programmers, we know that not all forms of a problem are computationally the same, because some can take advantage of particular programming languages or microprocessor features to reduce the clock cycles required for evaluation. Alan Zeichick concludes his by looking at tricks for ensuring data structure alignment and speeding up the evaluation of integer and floating-point math. In the first part of this series, we examined six ways to speed up C/C++ applications running on either 32-bit or 64-bit operating systems. Let's take a look at eight additional optimizations.

Optimizing Your C/C++ Applications, Part 1
Saved by uncleflo on August 17th, 2011.
Sidebar: Know the Code. A code profiler can help determine which parts of your application should be optimized. You should always use a profiler both before and after optimization to see if your change actually made an improvement—with C/C++, you can never be sure if your hand-tuning methods are better than those of your optimizing compiler! The smart engineers at AMD have spent a lot of time identifying places where C/C++ developers can optimize code for best performance. Some of these optimizations might look familiar—they're generally great coding practice for any 32-bit or 64-bit platform or operating system. In fact, most of these suggestions are appropriate whether you're developing 32-bit or 64-bit apps. Others are specifically for 64-bit applications running on the AMD64 architecture. This article will look at six optimizations; Part 2 will examine eight more.

Qt - A cross-platform application and UI framework
Saved by uncleflo on June 6th, 2011.
Qt allows you to write advanced applications and UIs once, and deploy them across desktop and embedded operating systems without rewriting the source code saving time and development cost. Whether you prefer C++ or JavaScript, Qt provides the building blocks — a broad set of customizable widgets, graphics canvas, style engine and more that you need to build modern user interfaces. Incorporate 3D graphics, multimedia audio or video, visual effects, and animations to set your application apart from the competition. With the new Qt Creator cross-platform IDE, or on its own, Qt is fast to learn and easy to use. And Qt's modular class library means that you can spend more time on innovation, and less time on infrastructure coding getting your software to market faster.

C syntax - Wikipedia, the free encyclopedia
Saved by uncleflo on February 23rd, 2011.
The syntax of the C programming language is a set of rules that specifies whether the sequence of characters in a file is conforming C source code. The rules specify how the character sequences are to be chunked into tokens (the lexical grammar), the permissible sequences of these tokens and some of the meaning to be attributed to these permissible token sequences (additional meaning is assigned by the semantics of the language).
