Building software from source

Posted Yesterday at 08:56 AM by hazel
Updated Yesterday at 09:39 AM by hazel

In the early days of Linux, a lot of people found themselves having to build programs from source. Nowadays many users have never done this or wanted to do it. And that can be seen as a great step forwards because it means that Linux is now an operating system for ordinary people and not just for hackers and geeks. And given all the bad things that one can say about Windows -- the instability, the malware, the constant "phoning home", the unfair EULA conditions, the invasions of privacy,...

What a Slackware derivative with dependency checking might look like

Posted 04-07-2021 at 05:56 AM by hazel
Updated 04-07-2021 at 06:16 AM by hazel

DISCLAIMER: This is not a serious suggestion. It's more of a jeu d'esprit, a philosophical exploration of how some limited degree of dependency checking might be introduced without damaging the essential structure of Slackware. The thing is certainly possible because Salix does it.

At present, the only newbie-friendly way to install Slackware is to do a full install, in which all dependencies are automatically satisfied. This is the recommended way to install and you will get little...

Disks, partitions and filesystems

Posted 10-27-2020 at 10:08 AM by hazel
Updated 10-27-2020 at 10:10 AM by hazel

One thing that Linux newbies often find confusing is the way that Linux deals with disks. Windows does its disk management "under the hood". Partitions are checked to see if they are organised in a way that Windows recognises; if so, they are automatically "mounted", i.e. made available to the system. Each disk or partition is given a letter by which it can be accessed, starting with C: (A: and B: were historically reserved for floppy disks). Unrecognised disks, including Linux...

Everything's a file

In most operating systems, a file is simply and solely a named block of data stored in a particular area or areas of a disk drive, which can be retrieved and optionally modified at will. In Unix systems like Linux, quite a few other things besides stored data masquerade as files. Hence the old joke that in Unix, everything's a file. It's not quite true but there is some truth in it. Things that aren't files but behave as if they were make Unix systems much simpler internally than many other OS's....

All kinds of version numbers

Posted 08-28-2020 at 05:44 AM by hazel

A novice in on of the LQ forums recently complained that he couldn't understand version numbers in Linux. That's not perhaps surprising because software version numbers are used in several different ways, often simultaneously. Every program or library that is in active development goes through different versions as its developer adds features or corrects reported bugs. The Linux kernel is no exception, for it is, after all a program. But over the years, the kernel versioning system has become a...
