Fancy writing a computer program in the C programming language?
The Turbo C 2.01 compiler has been restored to the Free C/C++ Compilers
and Interpreters page. I'm not sure when it got removed from my list, but I think it was around the time Borland sold
its development tools, and the new owners started removing the free compiler suites that Borland used to provide.
Anyway, it's back. For those not familiar with Turbo C, it was a famous C compiler known for its fast compilation,
built-in graphics library and IDE (development environment).
On the other hand, if you prefer a more up-to-date tool so that you can write computer programs for a modern system like Windows, Mac OS X, Linux (etc), take a look at the other free C or C++ compilers on the page. There are now 38 of them listed, so chances are that you should be able to find something you like.
- A new COBOL compiler for Windows has been added to the Free COBOL Compilers and Interpreters page. This compiler implements ANSI-74 COBOL with some features from ANSI-85 and ISO 1989:2002. If you're learning the COBOL computer language or want to write programs in COBOL, check it out.
- A new ping software has been added to the Free Graphical Ping Utilities to Check Network Connections page. Ping is often used as a rough test to see if a particular host (such as a website) on the network is reachable or alive. While most operating systems, including Windows, Mac OS X and Linux, already come with command line ping software , these Ping tools have a graphical interface and often include additional facilities not present in the built-in programs. All the programs listed on the page are free.
- A new screen reader has been added to the Free Screen Readers: Text to Speech Conversion page. Screen readers read whatever is displayed on your monitor aloud, so that the blind can use computers to read and write documents, surf the Internet, etc. If you are a webmaster, you can also use such readers to test your website to make sure it is accessible to the blind.
- New page: How to Created Rounded Corners for Your Box Borders in CSS. Tired of putting retro rectangular boxes with right-angled corners on your web pages? This article teaches you how to create boxes with rounded corners to enclose your text and/or pictures, giving it a more modern look. And you don't even need to do tedious things like slice images: the tutorial uses Cascading Style Sheets (CSS) to accomplish the job.
- Do you fancy creating your own PDF ebook? Or perhaps you simply want to convert a document into the PDF format? Check out the newest entry in the Free PDF Converters, Editors and Printer Drivers page. There are now 11 PDF conversion tools on that page, so even if you don't like the latest addition, there are many others to choose from. Besides, they are all free: you can get them all if you like.
- Another frequently asked question (FAQ) has been added to the How to Add a CAPTCHA Test to Your Feedback Form Script: Reducing Spam in Your Contact Form article. This one deals with how to solve the problem of the ReCAPTCHA service rejecting your CAPTCHA test after you move your site to a new domain.
- Do you have a huge file that you want to send someone but find that it is too large to attach in an email? The newest utility to be added to the Free File Splitters and Joiners page lets you split that file into smaller chunks so that it can be transmitted to someone else and provides an easy-to-use way for them to reassemble the file back together again. It even checks the integrity of the file after recombining it to make sure it's identical to the original.
- A new C library that lets you easily write 2D graphical games (complete with sound) on Linux has been added to the Free 2D and 3D Game Engines, Games Programming Libraries and Source Code page. There are also other free libraries on that page that let you write games for other systems, like Windows, Mac OS X, Linux, etc.
- A new C cross-compiler for the AVR series of microprocessors has been added to the Free C/C++ Compilers and Cross-Compilers for Microcontrollers, PDA, Calculators, Embedded Systems and Other Devices page. This one is hosted on Windows. Note: if you're just looking for an ordinary C or C++ compiler for your computer, please see the Free C/C++ Compilers and Interpreters page instead.
- Do you have this nagging feeling that you have multiple copies of the same file on your computer, possibly under different filenames? Now you can find out, and get rid of the duplicates if you wish, with the latest software to be added to the Free Find / Delete Duplicate Files Utilities. This program checks the file on your system for duplicates, even if those files are in diverse locations, with different filenames and dates. It allows you to clean up your system and free your disk space.
- A new clipboard manager has been added to the Free Clipboard History Managers and Extenders page.

- A new open source operating system, designed with security in mind, has been added to the Free Alternative Operating Systems page.

Not only are programs isolated from each other, but even some system components (eg networking and storage) are also sandboxed.
