New GitHub account and some SlackBuilds updated

Nov

2016

As I said in the previous post, I was in doubt regarding the fact of continuing or not to provide prebuilt packages. Nowadays there are more tools that help Slackware users with the installation of third-party software, compared to the past. This applies both to the installation via SlackBuild scripts and the one from prebuilt ...

2016

Here we are! In the last period, during my spare time, I worked on various SlackBuilds. The first of these is I-Nex, a system information tool like the well-known Windows software CPU-Z. I had to wait to build it because it requires libprocps which was not included before the version 14.2 of Slackware. The second one ...

2016

Slackware 14.2 has been finally released, so I decided to (re)create some new prebuilt packages for this version. The packages (for which I also maintain the SlackBuild scripts at SlackBuilds.org) are libcpuid, libmseed and packETH.

Obviously, to do this I used a VirtualBox virtual machine, since my host OS is a Linux distro. Once I finished to work I simply ...

2014

In the last period I was working on a project concerning UPnP. In particular I was developing a “smart speaker”, a wireless speaker which plays mp3 files by streaming them from a NAS (UPnP media server). The code is written in Java and leans to mpg123, a real time CLI MPEG audio player/decoder. The hardware ...

In the last days I was trying to create some packages for Slackware 14.1. I’ve created two virtual machines with VirtualBox, one for the 32 bit version and the other for the 64 bit version. These VMs have a clean Slackware installation and are intended to be used only for building packages. I’ve configured slackpkg ...

Jul

2014

My attention is focused on this specific USB device: Toshiba DVB-T TV tuner P/N PX1211E-1TVD. I got it together with my old laptop in the summer of 2006. Albeit this DVB-T TV tuner comes with a standalone mini antenna, I usually prefer to connect it directly to the TV antenna cable using the adapter. This ...
