Installing SELinux

Last Revised: 2024-11-12 This article provides notes on how to install Security Enhanced Linux (SELinux) on an Ubuntu 22.04 Linux system. These notes are based on my experience doing this installation and some issues I encountered. Other online resources describe this procedure, but the ones I encountered are either old, incomplete, give bad advice, orContinue reading “Installing SELinux”

A Collection of Notes

Finally, I have decided what I would like to do with this blog. I will use it to store notes on how to do various (technical) things. Often, I need to work out the details of how to install and configure a package, how to make use of some software library, or how to implementContinue reading “A Collection of Notes”

Restart?

It has been 12 years since I last posted anything here. I think the time has come (probably long overdue) for me to restart this blog in some useful way. However, I’m not sure I want to follow the original vision I had for this blog when I started it. Much has happened since thenContinue reading “Restart?”

Exception Specifications

Both C++ and Java (and other programming languages as well) support a notion of exception specifications. The design and even the desirability of these specifications is controversial. In C++, for example, the exception specifications are enforced at run time; if a function throws an unexpected exception the running program is (by default) aborted. In JavaContinue reading “Exception Specifications”

Project Wheel

Not long ago the Visual Studio installation on my main laptop decided to not work. Specifically, as soon as I opened any project Visual Studio closed immediately without any messages of any kind. The problem turned out to be related to the VMware plug-in for Visual Studio. Any heavy computer user is going to encounterContinue reading “Project Wheel”

Discovering OpenSolaris

I’m back! I’ve decided to give blogging another try. Maybe I’ll find my blogging groove this time around. Or maybe I just like playing around with WordPress! I was recently introduced to OpenSolaris, the open source version of the Solaris operating system. I downloaded the base system from the OpenSolaris web site and installed itContinue reading “Discovering OpenSolaris”

Indefinite Hold

I’ve had this blog for about eight months and yet I’ve only posted a few entries in it. Honestly I don’t have all that much to say, and I don’t want to talk just to hear myself talk. Instead of spending time maintaining this blog I find that I’d rather spend time working on oneContinue reading “Indefinite Hold”

Email + IM?

It is common to find single applications that integrate several services that could have sensibly been provided with separate applications instead. How much integration is smart is, of course, a matter of opinion. I think integration makes sense if the things being integrated are closely related and can reasonably share application features. For example, ThunderbirdContinue reading “Email + IM?”

Notepad++

I have a thing for editors it seems. Over the years I’ve used quite a variety of different ones. I’ve even written an editor of my own. As I mentioned in an earlier post, I’ve recently taken to using jEdit for my day to day editing needs. However any editor as powerful as jEdit isContinue reading “Notepad++”

Is jEdit a Worthy Replacement for Emacs?

I am a long time Emacs user. Yet although I’m comfortable with the editor, I have never really achieved “power user” status with it. I dabbled with some macros and I fiddled around with my .emacs file, but I never got around to creating any non-trivial code to extend the editor in a useful way.Continue reading “Is jEdit a Worthy Replacement for Emacs?”
