Its like TV. Very few good channels and many bad channels. Or like books. Very few good books and many bad books. Look for spezialized channels and educate your children. Read the bible.com . But only Jesus is reliable. Forget Moses and the punishing God.
@kat@yarn.girlonthemoon.xyz On the one hand, all these programs have a very long history and the technology behind manpages is actually very powerful â you can use it to write books:
https://www.troff.org/pubs.html
I have two books from that list, for example âThe UNIX programming environmentâ:
https://movq.de/v/c3dab75c97/upe.jpg
Itâs a bit older, of course, but it looks and feels like a normal book, and it uses the same tech as manpages â which I think is really cool. đ
Itâs comparable to LaTeX (just harder/different to use) but much faster than LaTeX. You can also do stuff like render manpages as a PDF (man -Tpdf cp >cp.pdf) or as an HTML file (man -Thtml cp >cp.html). I think I once made slides for a talk this way.
On the other hand, traditional manpages (i.e., ones that are not written in mandoc) do not use semantic markup. They literally say, âthis text is bold, that text over here is italicsâ, and so on.
So when you run man foo, it has no other choice but to show it in black, white, bold, underline â showing it in color would be wrong, because thatâs not what the source code of that manpage says.
Colorizing them is a hack, to be honest. Youâre not meant to do this. (The devs actually broke this by accident recently. They themselves arenât really aware that people use colors.)
If mandoc and semantic markup was more commonly used, I think it would be easier to convince the devs to add proper customizable colors.

Nobody want to be a shitty programmer. The question is: Do you do anything not to not be one?
Reading blogs or social media and watching YouTube videos is fun. After them, your code may be a little better, of course. But you need a lot. You need to study! Read good books and study the code of other programmers, for example. Maybe work with a new language, architectures and paradigms. You need break the routine.
If you know Object-oriented programming, you learn functional programming.
If you know Model-View-Controller, you learn Model-View-ViewModel.
If you donât know anything about architectures, you learn Clean Architecture, Hexagonal Architecture, etc.
If you know Python, you learn Ruby or Go.
If you know Clojure or Lisp⊠you donât need to learn anything else. You are already a good programmer. Just kidding. You can learn Elixir or Scala.

@movq@www.uninformativ.de I started with Delphi in school, the book (that we never ever used even once and I also never looked at) taught Pascal. The UI part felt easy at first but prevented me from understanding fundamental stuff like procedures or functions or even begin and end blocks for ifs or loops. For example I always thought that I needed to have a button somewhere, even if hidden. That gave me a handler procedure where I could put code and somehow call it. Two or three years later, a new mate from the parallel class finally told me that this wasnât necessary and how to do thing better.
You know all too well that back in the day there was not a whole lot of information out there. And the bits that did exist were well hidden. At least from me. Eventually discovering planet-quellcodes.de (I donât remember if that was the original forum or if that got split off from some other board) via my best schoolmate was like finding the Amber Room. Yeah, reading the ITG book would have been a very good idea for sure. :-)
In hindsight, a console program without the UI overhead might have been better. At least for the very start. Much less things to worry about or get lost.
Hence, Iâd recommend to start programming with a console program. As for the language, not sure. But Python is probably a good choice, it doesnât require a lot of surrounding boilerplate like, say Java or Go. It also does exceptionally well in the principle of least surprise.

5 self-help books that changed my life â Read more
well, there is a whole book about piracy, DRM and selling stuff on the internet.
https://en.m.wikipedia.org/wiki/Information_Doesn%27t_Want_to_Be_Free
So I wonât add much to the topic, what I can say is that this is about being pragmatic. There is some people whoâs gonna spend their money on books but it requires publicity (polemic topic) and subsidizing creativity with our own money (another controversial one).
Otherwise itâs a difficult discipline /profession /industry
@prologic@twtxt.net @eapl.me@eapl.me I want to highlight another social problem: People donât read. Paper industry is a bad moment because people donât pay for books; it does not matter if it is a physical or digital platform. I have this information because I have a good friend who left the industry after publishing a magazine, books and working in an editorial. DRM is a try to give some more money.
well, that leads to a long conversation.
Piracy is a difficult topic which is very personal, so I wonât say much about it.
On writing books, Iâve tried along with other digital products such as courses and videogames, and I got to confess that it has been hard for me.
If it helps, I think it all reaches our expectations on the activity and the result. If royalties is the expectation, itâs going to be slow. By 5% of royalties, for a rough example, a huge amount of sales will be required to get a decent âwageâ, so Iâve understood of doing it by the side of a normal employment although it has been discouraging and a bit sad.
I have reflected about it in Spanish here: https://sembrandojuegos.substack.com/p/sobre-expectativas-al-crear-juegos
@prologic@twtxt.net Fully agreed. Iâm far more likely to buy such mediums when DRM-free. I never go near Amazon eBooks etc because of their lock-in, and I have a Kobo eReader which needs to have the books side loaded unless directly from the Kobo store. I prefer DRM-free files every time.
I have just received the royalties for the last book: 98 euros for the four-month period, about 24 euros a month on average. Not even enough for the gym membership.
If you have to keep some knowledge: donât write for money, the paper (or ebook) industry is in a very bad way, the margins for the author are very small and piracy is devastating.

@kat@yarn.girlonthemoon.xyz Pointers can be a bit tricky. I know it took me also quite some time to wrap my head around them. Let my try to explain. Itâs a pretty simple, yet very powerful concept with many facets to it.
A pointer is an indirection. At a lower level, when you have some chunk of memory, you can have some actual values sitting in there, ready for direct use. A pointer, on the other hand, points to some other location where to look for the values oneâs actually after. Following that pointer is also called dereferencing the pointer.
I canât come up with a good real-world example, so this poor comparison has to do. Itâs a bit like you have a book (the real value that is being pointed to) and an ISBN referencing that book (the pointer). So, instead of sending you all these many pages from that book, I could give you just a small tag containing the ISBN. With that small piece of information, youâre able to locate the book. Probably a copy of that book and thatâs where this analogy falls apart.
In contrast to that flawed comparision, itâs actually the other way around. Many different pointers can point to the same value. But there are many books (values) and just one ISBN (pointer).
The pointerâs target might actually be another pointer. You typically then would follow both of them. There are no limits on how long your pointer chains can become.
One important property of pointers is that they can also point into nothingness, signalling a dead end. This is typically called a null pointer. Following such a null pointer calls for big trouble, it typically crashes your program. Hence, you must never follow any null pointer.
Pointers are important for example in linked lists, trees or graphs. Letâs look at a doubly linked list. One entry could be a triple consisting of (actual value, pointer to next entry, pointer to previous entry).
_______________________
/ ________\_______________
â â | \
+---+---+---+ +---+---+-|-+ +---+---+-|-+
| 7 | n | x | | 23| n | p | | 42| x | p |
+---+-|-+---+ +---+-|-+---+ +---+---+---+
| â | â
\_______/ \_______/
The âxâ indicates a null pointer. So, the first element of the doubly linked list with value 7 does not have any reference to a previous element. The same is true for the next element pointer in the last element with value 42.
In the middle element with value 23, both pointers to the next (labeled ânâ) and previous (labeled âpâ) elements are pointing to the respective elements.
You can also see that the middle element is pointed to by two pointers. By the ânextâ pointer in the first element and the âpreviousâ pointer in the last element.
Thatâs it for now. There are heaps ;-) more things to tell about pointers. But it might help you a tiny bit.
