The cloud isn't killing open source software

11 hours 16 min ago

Over the last few months, I participated in two keynote panels where people asked questions about open source licensing:

  • Do we need to redefine what open source means in the age of the cloud?
  • Are cloud vendors abusing open source?
  • Will open source, as we know it, survive?

Last year was the most eventful in my memory for the usually very conservative open source licensing space:

Moving files on Linux without mv

Monday 19th of August 2019 07:01:00 AM

The humble mv command is one of those useful tools you find on every POSIX box you encounter. Its job is clearly defined, and it does it well: Move a file from one place in a file system to another. But Linux is nothing if not flexible, and there are other options for moving files. Using different tools can provide small advantages that fit perfectly with a specific use case.

Before straying too far from mv, take a look at this command’s default results. First, create a directory and generate some files with permissions set to 777:

WebAssembly for speed and code reuse

Monday 19th of August 2019 07:00:00 AM

Imagine translating a non-web application, written in a high-level language, into a binary module ready for the web. This translation could be done without any change whatsoever to the non-web application's source code. A browser can download the newly translated module efficiently and execute the module in the sandbox. The executing web module can interact seamlessly with other web technologies—with JavaScript (JS) in particular. Welcome to WebAssembly.

When you try to shoehorn an idea, approach, or code into a situation that's not expecting it, you get surprising and fun results.

In his Lightning Talk at the 17th annual Southern California Linux Expo (SCaLE 17x), "Writing Kubernetes controllers 'the wrong way' is still useful," sysadmin Chris McEniry shares his experience with an out-of-cluster etcd-controller.

How to encrypt files with gocryptfs on Linux

Friday 16th of August 2019 07:02:00 AM

Gocryptfs is a Filesystem in Userspace (FUSE)-mounted file-level encryption program. FUSE-mounted means that the encrypted files are stored in a single directory tree that is mounted, like a USB key, using the FUSE interface. This allows any user to do the mount—you don't need to be root. Because gocryptfs encrypts at the file level, synchronization operations that copy your files can work efficiently on each file.

How to plan your next IT career move

Friday 16th of August 2019 07:01:00 AM

Being part of technology-oriented communities has been an essential part of my career development. The first community that made a difference for me was focused on virtualization. Less than a year into my first career-related job, I met a group of friends who were significant contributors to this "vCommunity," and I found their enthusiasm to be contagious. That began our daily "nerd herd," where a handful of us met nearly every day for coffee before our shifts in tech support.

How to create a vanity Tor .onion web address

Thursday 15th of August 2019 07:02:00 AM

Tor is a powerful, open source network that enables anonymous and non-trackable (or difficult to track) browsing of the internet. It's able to achieve this because of users running Tor nodes, which serve as intentional detours between two otherwise direct paths. For instance, if you are in New Zealand and visit python.nz, instead of being routed next door to the data center running python.nz, your traffic might be routed to Pittsburgh and then Berlin and then Vanuatu and finally to python.nz.

How to install Python on Windows

Wednesday 14th of August 2019 07:00:00 AM

So you want to learn to program? One of the most common languages to start with is Python, popular for its unique blend of object-oriented structure and simple syntax. Python is also an interpreted language, meaning you don't need to learn how to compile code into machine language: Python does that for you, allowing you to test your programs sometimes instantly and, in a way, while you write your code.
