Linux Mint 17: Hands-on with UEFI Secure Boot

Filed under
Reviews
HowTos

Oh, one last comment about UEFI boot to close this post. As was the case with the previous Mint 16 release, the UEFI boot directory will be named 'ubuntu', so if you want to install Mint 17 and Ubuntu both on the same UEFI boot system, you will have to be careful about that.

The most obvious solution, renaming the boot directory after the first of them is installed, doesn't work (it won't boot that one any more). The solution I have found which does work is to create a second EFI Boot partition, but neither Ubuntu nor Mint will let you specify the UEFI boot partition to use on installation, so you have to copy the boot directory to the second EFI partition after installing. This is not a big deal, if you are "advanced" enough to be installing both distributions on one system, then you should also be able to handle this.

WRITE YOUR FIRST LINUX KERNEL MODULE

Filed under
Linux
HowTos

Probably the easiest way to start kernel programming is to write a module – a piece of code that can be dynamically loaded into the kernel and removed from it. There are limits to what modules can do – for example, they can’t add or remove fields to common data structures like process descriptors. But in all other ways they are full-fledged kernel-level code, and they can always be compiled into the kernel (thus removing all the restrictions) if needed. It is fully possible to develop and compile a module outside the Linux source tree (this is unsurprisingly called an out-of-tree build), which is very convenient if you just want to play a bit and do not wish to submit your changes for inclusion into the mainline kernel.

Create a game with Scratch on Raspberry Pi

While Scratch may seem like a very simplistic programming language that’s just for kids, you’d be wrong to overlook it as an excellent first step into coding for all age levels. One aspect of learning to code is understanding the underlying logic that makes up all programs; comparing two systems, learning to work with loops and general decision-making within the code.

Open source history, present day, and licensing

Looking at open source softwares particularly, this is a fact that is probably useful to you if you are thinking about business models, many people don't care about it anymore. We talk about FOSS, Free and Open Source Software, but if we really are strict there's a difference between free software and open source software. On the left, I have free software which most typically is GPL software. Software where the license insures freedom. It gives freedoms to you as a user, but it also requires that the freedoms are maintained. On the right-hand side, you have open source software which is open for all, but it also allows you to close it. So here we come back to the famous clause of the GPL license, the reciprocity requirement which says, "If I am open, you need to be open." So software that comes under the GPL license carries with it something that other people call a virus. I call it a blessing because I think it's great if all software becomes open. Read more

Mozilla Wants to Save the Open Web, but is it Too Late?

Again, I think this is absolutely correct. But what it fails to recognise is that one of the key ways of making the Web medium "less free and open" is the use of legally-protected DRM. DRM is the very antithesis of openness and of sharing. And yet, sadly, as I reported back in May, Mozilla has decided to back adding DRM to the Web, starting first with video (but it won't end there...) This means Mozilla's Firefox is itself is a vector of attack against openness and sharing, and undermines its own lofty goals in the Open Web Fellows programme. Read more
