Java Code ist unstrukturierter trockener Staub von Codefragmenten in Klassendateien, die inert in keiner Weise miteinander interagieren. Erst mit den passenden Factories, Delegates, Generators und ClassLoaders werden sie instanziiert und zusammengesetzt. Der entstehende Haufen an Querverweisen führt dann nur zufällig irgendwann einmal tatsächlich wirksamen Code aus.
In this course, students will learn to develop complex system-level software in the C programming language while gaining an intimate understanding of the Unix operating system (and all OS that belong to this family, such as Linux, the BSDs, and even Mac OS X) and its programming environment.
Topics covered will include the user/kernel interface, fundamental concepts of Unix, user authentication, basic and advanced I/O, fileystems, signals, process relationships, and interprocess communication. Fundamental concepts of software development and maintenance on Unix systems (development and debugging tools such as "make" and "gdb") will also be covered.
Students are expected to have a good working knowledge of the C programming language, have written non-trivial programs before, and to be able to competently use a Unix system with a command-line shell interface. All coursework will be done exclusively on a Unix system from the command-line. This is not an introduction to using Unix!
I wrote a post over the weekend which said a lot about libraries letting people down, and other people becoming overly dependent on them. There was an aside of sorts in there which mentioned teaching people about all of the things to look out for when you're writing to a file on a Unix-ish/POSIX-ish filesystem situation. A friend reached out asking if I had a post talking about that stuff, and near as I can tell, I do not.
That brings us to right now. I will attempt to lay down a few things that I keep in mind any time I'm creating files.
Linking-it-all-together asks: I came across this article about the benefits of static linking over dynamic linking. If dynamic linking is slower and doesn't offer practical benefits then why do most distros still dynamic link? Is this a hold over from the past or is there a reason I'm missing that make distros still use dynamic linking?
DistroWatch answers: I read through the article provided and it does share some interesting statistics on dynamically linked programs versus statically linked programs. The author appears to be making a case against dynamic linking and in favour of static linking, or at least presenting facts which would support such a case. For the sake of this discussion I am going to assume the observations the article's author makes are accurate and factually correct, at least for their own distribution.
The author addresses some interesting questions, such as how often are dynamically libraries used on the system, which indicates how many resources avoid duplication by sharing libraries. They also explore how quickly dynamic and static programs load and how much larger statically linked programs are compared to their dynamically linked counterparts. The author points out that many libraries on their distribution are not shared by many programs, that statically linked programs can load faster, and that not a lot of bandwidth is saved by using dynamically linked programs.
Reading through the page of observations the author shares, it's understandable we might wonder why developers continue to favour dynamically linked applications in most situations. Let's look at some of the specific arguments from the article.

we'll take a behind-the-scenes look at the design and development of Btrfs on many levels — technical, political, personal — and trace it from its origins at a workshop to its current position as Linus's root file system.
