- Two more emulators have been added to the Free Amiga Emulators page. One of them runs in a modern web browser (which means it can work on Windows, macOS, Linux, etc), and the other works on the Playstation Portable (PSP). (For those wondering, Amiga emulators are software that allow you to run Amiga programs and games on your modern computers, by mimicking the original Amiga computers.)
- Another C compiler has been added to the Free C/C++ Compilers and Interpreters page. There are now about 32 C or C++ compilers on that page, and that's not even counting the ones listed separately for microcontrollers, PDAs, calculators and embedded systems. For those who don't know what these are, loosely speaking, C and C++ compilers let you create your own computer programs.
- New page: How to Add an Audio or Music File to a Web Page with BlueGriffon. BlueGriffon has built-in facilities for you to insert an audio clip or music file into your web page. This article shows you how to use it.
- GW-BASIC has been released as open source by Microsoft, and thus has been added to the Free BASIC Compilers and Interpreters page. For those not familiar with this program, it is a BASIC interpreter that was bundled with MS-DOS for umpteen years, and many people learnt ("learned") to write computer programs in those days by experimenting with it.
- New page: How to Draw a Rectangular Box Around Your Content in BlueGriffon. This article deals with how to use the BlueGriffon web editor to draw lines around text and/or images on a web page, so as to put them into a box, setting them apart from their surrounding content.
- Another free service has been added to the Free Source Code Hosting Services page. This one not only allows you to host software projects, but you can also use it to create websites containing free content on any subject. You can use your own domain name for the site, or the free web address they provide.
- New page: How to Insert a Bullet Point (Unordered) List with BlueGriffon. This article shows you how to insert a bullet point list (where each item on the list is marked with a solid black circle rather than numbered) into a web page using the BlueGriffon web editor.
- New page: Free Video Conferencing Software. If you are looking for video conferencing software, either to conduct virtual meetings, online courses, or even just to collaborate on a project or document, take a look at these free open source software. With these, you don't have to rely on third-party online services over which you have little or no control.
- New page: How to Start a List with a Number Other than 1 and Still Have it Automatically Numbered (HTML). What happens if you want to create a list of items, but don't want to start counting from 1 (eg, you want the list to start from item 4)? This article shows you how to do it, and still use the HTML ability to automatically number the list, and keep the numbers up-to-date even when you add items to (or delete them from) the middle.
-
Two new programs have been added to the
Free File Synchronization Software
page. One of them can even back up across a local network and the Internet. As everyone who has worked on a computer
for some time knows, it is very important to back up (at the very least) your data onto a separate device on a
regular basis, since computers can fail at unexpected times. Software like these are used to automatically
mirror the data on your main computer with your backup drive or system, so that it is kept up to date.
Note: if you want to back up an entire computer, and not just your data, please see the Free Hard Disk Backup and Restore, Hard Disk Image and Cloning Utilities page instead.
- New page: How to Insert a List that Automatically Numbers/Renumbers Itself with BlueGriffon. This article shows you how to add a list to your web page that automatically numbers itself. This way, you don't have to go through the whole list to renumber everything when you add to the middle of the list or when you delete items from it.
- A new SQL database server has been added to the Free Database Libraries and SQL Servers page. This one is column-oriented, potentially increasing its performance (over the usual row-oriented database management systems).
- New page: What to do if a registrar quotes an exorbitant price for a domain. One of my visitors told me that a domain name registrar quoted a "ridiculous price" for a domain he wanted, and asked if there was any way around it. This article answers that question.
- A Python compiler has been added to the Free Python Compilers and Interpreters page. This one works on Windows, macOS and Linux, and can generate standalone binary distribution packages for your program.
- New page: How to Rotate an Image on a Website When Viewed on a Mobile Phone (CSS). In response to a visitor's query, this article deals with how you can turn an image on its side when a web page is viewed on a mobile phone.
- Another PHP script that can generate CAPTCHA images has been added to the Free PHP CAPTCHA Scripts page. Such scripts are meant to be used in conjunction with forms on your website to cut down the amount of spam dumped into them. (For those who don't really know how to write PHP programs, or can't be bothered to write your own script, one quick and simple way is to generate a contact form, complete with CAPTCHA integrated using the Feedback Form Wizard. It's free too.)
- A new compiler has been added to the Free PHP Compilers page. This one can compile PHP 7.1 code into a .NET program that can run on Windows, macOS and Linux systems. Such compilers are useful for people who want to write computer software in the PHP programming language that run on normal desktop or laptop computers.
- New page: How to Stretch a Background Image to Fill an Entire Web Page (or Column) in BlueGriffon. This article deals with how you can use BlueGriffon to stretch a picture that is used as the backdrop of a web page, so that it fills the entire page, column or section.
- A new site has been added to the Free Royalty-Free Stock Photos page. This one provides both free photos and videos which you can use without paying royalties on your own website, presentations, etc.
- A new icon editor for Windows and Linux has been added to the Free Resource Editors, Compilers and Icon Editors page. Icon editors are useful for webmasters wishing to create a favicon for their website as well as programmers who want to make one for their software.
- New page: How to Change the Message Shown Before the Comments Field in WordPress. If you run a WordPress blog, and want to customize the message that is shown in the "Leave a Reply" section of your post (where you visitors enter their comments), this article shows you how, using a method that will allow your changes to persist even when your theme files auto-update.
- New page: How to Use Google Fonts and Other Web Fonts in BlueGriffon. This article describes how you can add Google Fonts and other web fonts to BlueGriffon for use with your website.
- New page: Free Geolocation Services. If you are thinking of customizing your website so that it shows different content for different countries (eg, display prices of goods in the local currency), these free geolocation services may be just what you need.
- A free service has been added to the Free Dynamic and Static DNS Services and Name Servers page. This one provides dynamic DNS for those whose websites are hosted on their own computer and who connect to the Internet with an address that changes each time. To avoid confusion, please note that these are not services that give you free domains. You will still need to obtain a domain name from a registrar. In addition, for the average person who wants to create a website the standard way, you don't need these services.
- Another free service has been added to the Free Web Hosts page. If you want to create a website and don't want to pay for web hosting, take a look at these free hosts on which you can place a site.
- A new site has been added to the Free Mailing List Hosting and Email Newsletter Hosting page. It is useful if you are interested in starting an email mailing list, whether an announcement list or a discussion one.
- A new implementation of Common Lisp for Windows, Mac OS X, Linux and FreeBSD has been added to the Free Common Lisp Compilers and Interpreters page. This one can create standalone executables for your programs. (For those wondering, Common Lisp is a general purpose programming language.)
- Updated: How to Make / Create a Website. If you are thinking of designing a website, whether a business or hobby site, read How to Create a Website. The article has been updated with the latest developments on the Internet.
- New page: Can I Change My Website's Address to HTTPS Without Getting an SSL Certificate? This article answers a question asked by a visitor on whether he can simply update all the URLs on his website to "https" without obtaining an SSL certificate, and, if not, why.
- Two more programs have been added to the Free Standard ML Compilers page. Standard ML is a general purpose functional programming language. Both programs added (one is a compiler, and the other an interpreter) are open source.
- New page: How to Make a Button Run a Server-Side Script (eg, a PHP, Perl, or Python Script) (HTML). I was asked by a visitor how he could make a button run a server-side script (such as a PHP, Perl or Python script). This article answers that question.
- A new debugger for Windows DLL and EXE files has been added to the Free Debuggers and Bug Trackers page. (For those wondering, debuggers are software that help programmers track down bugs in their programs.)
- New page: How to Add a (Self-Hosted) Video to Your Website with Expression Web. Find out how you can insert a video into your web page with the free Microsoft Expression Web editor. The video, in this case, will be placed on your website itself (ie, self-hosted) and not on a video sharing site.
- Another lint-type program has been added to the Free Static Code Analyzers page. This one scans your C or C++ program source code for a huge variety of potential bugs/errors. It works on Windows, but can apparently be compiled to run on Linux and other Unix-type systems.
- A new Windows program has been added to the Free Command Line Shells page. This open source software supports backquotes (where the output of a command is inserted into the command line of another), background processing (run programs in the background), aliases, tab completion, extended wildcard/filename-matching, and so on.
- New page: How to Prevent Your Website from being Placed in a Frame. By default, anyone can place your website in a frame or iframe, for the purposes of clickjacking, altering your content, or putting advertisements on your page. This article shows you how to prevent this, using both the older backward-compatible method as well as the modern officially-recommended one.
- New page: How to Move a Website from Dreamweaver to BlueGriffon. I was asked by a visitor how he could move his website from Dreamweaver to the free BlueGriffon web editor. This article answers that question.
- A new program has been added to the Free CD, DVD and Blu-Ray Burning Software page. This one can not only create data discs but also audio CDs, rip (ie, copy) music from CDs, make ISO images, burn ISO images, create multi-session discs, erase discs, etc. It's useful for those who find the built-in facilities provided by Windows too limited.
