Microsoft released MS-DOS 1.25 and 2.0 through the Commuter History Museum a few years ago. Now the company has broadened the release of these 1980s operating systems by putting g the software on GitHub.

GitHub is pretty much the biggest game in town when it comes to sharing software development projects. But it can be challenging to ensure projects are saved without accidentally revealing credentials and other secrets. Microsoft has offered some some advice and tools to help protect against accidentally revealing confidential data.

The idea of a multi-user operating system is almost a tautology today but back in the 1980s it wasn't all that common - at least when it came to personal computing. PC-MOS was a multi-user operating system that, like DR-DOS and others, competed with Microsoft's MS-DOS before eventually disappearing at the Redmond juggernaut crushed almost all its competition. Now, Roeland Jansen, Gary Robertson and Rod Roark have put the operating system onto GitHub as an open source project so we can all mess with its source code.

As your programming skills increase, it becomes more important that you maintain a consistent coding style. When it comes to curly bracket placement, capitalisation and variable naming, it's best if you and your fellow developers are all on the same page.

Following on its decision to close down CodePlex, Microsoft has announced that Windows App Studio will be closed down on 1 December 2017. It will be superseded by the Windows Template Studio.

GitHub has added a bunch of new tools to their platform. Using the GitHub GraphQL API, you can now create your own tools, there have been enhancements made to project boards and new tools for organising repositories have been added. There are also a bunch of bug fixes and the ability to deprecate TLS protocols in order to enhance application security.

With Microsoft shutting down their code repository, CodePlex, recently and conceding that coders prefer GitHub, it's interesting to look at what projects coders from around the world are looking at. Felipe Hoffa, a developer advocate at Google, has done some analysis to find out what the most popular GitHub projects with a country-by-country analysis.

In a recent blog post, Microsoft has announced that it's shutting down it's code repository and sharing platform CodePlex. Launched just over a decade ago, CodePlex has been usurped by GitHub, which Microsoft says they are partnering closely with.

TruffleHog is a tool that can hunt down high-entropy encryption keys that may have been accidentally committed to git repositories.

Since launching in 2009, GitHub has become the biggest Git repository hosting service in the world and is used by millions of individuals and businesses to manage software projects. It has also become a playground for open-source software projects that often involve a large number of contributors. When there are a lot of cooks in the kitchen, it can become chaotic and scare off beginners. If you are a software developer that's ready to enter the GitHub fray, we have some advice on what to do -- and what not to do -- when you're contributing to a project in a Git repository.

As we reported last month, the open-sourcing of Microsoft's PowerShell appeared a done deal. Now, a month later, the company has made the whole thing official, publishing the source to GitHub, along with Linux and OS X flavoured binaries.

Google has never shied away from building operating systems -- just look at Chrome OS and Android. The thing is, they're both based on Linux and while it's open-source and incredibly flexible, it might not be up to the task for Google's future conquests. Enter "Fuchsia", a new, non-Linux OS the company appears to be developing.

Microsoft looks like it'll continue to feed its addiction to open-sourcing its technology (both internal and acquired), with new information suggesting the company's PowerShell framework is next in line.

It's easy to forget that GitHub can host any sort of content, not just source code and data for your personal or business projects. This means GitHub can unintentionally become a server of copyright-infringing material, a fact the company takes seriously -- it shut down over 8200 projects during 2015, with nearly 6000 closed in September alone.

GitHub has been slowly and steadily improving its platform. Just this year it's introduced browser file uploads, commit "reactions" and user blocking. These were nice, but didn't add much to the service's appeal. Unlimited private repositories however? That's not bad.

GitHub is a git repository service widely used to host open source software projects. The beauty of open source projects on GitHub is that people can collaborate to edit and improve the code. Trouble is, with multiple people working on the same project, it can get a bit chaotic and one uncooperative coder can ruin it for everybody. This is why GitHub is now letting project owners of public repositories block abusive users.

Hot on the heels of adding browser file uploading, GitHub has taken the wraps off another feature for its web-facing presence -- reactions. Yes, you can now better share you feelings regarding issues, comments and pull requests on GitHub using good old emoticons.

New GitHub features are always welcome, though some a certainly more useful than others. On the "less handy" end of the spectrum is the recent addition of file uploading via the browser to your GitHub-hosted repositories.

Code repository hosting service GitHub has updated its enterprise offering to provide more support for development teams within large companies. GitHub Enterprise 2.5 is focused on making it easier for teams to add new users to their software projects, facilitating secure collaboration and weeding out performance issues that crop up when working with large groups of developers.
