The case for biparted project structure ( build/src )
I always structure my projects in two main directories: build and src. Build contains "dynamic", temporary, possibily auto-generated stuff. Src contains human-made stuff.
This policy is quite rigid, with very few carefully considered exceptions.
Why ?
Let’s say you want to take the lazy route and put everithing together without much regard.

Blogpost idea: dealing with bad containers
Talk about: - containers that do not allow to mount config in a volume-friendly way examples: windmill, element-web
-
bad docker-compose practices: i.e. direct bind mounts

About OOP and theoretical technical righteousness
See Stroustup OOP. Because one influential person says something condivisible, it is that "right" ?
Models are just models
Standards are so only if they get largely accepted
Distinction
Exobrain is a weakly structured blog without constraints on content.
Blog is the place for curated essay-like documents. A blog post should be at least three paragraphs long. Paragraphs should be dense, about 10 periods. Incorporates a lot of qualities typical of essays.

Adding CoW capabilities to SQLite
-
Using BTRFS snapshots ?
-
Adds dependency on host system. May be necessary using a bundled BTRFS image. Is BTRFS-on-VFS supported ?
-
Apparently no, and for good reason:
link:https://btrfs.readthedocs.io/en/latest/Hardware.html#storage-model
With such configuration many assumptions BTRFS makes on storage will be broken. Data corruption guaranteed on the long term.

-
Someone built a SQLite-like DBMS with builtin CoW capabilities. Interesting, but not stable and thus not trustable.

Nix ecosystem criticalities
Nix is a very interesting project that aims to solve fundamental issues of traditional package management systems. However itself presents some issues that makes its adoption difficult.

Graphite pencil’s hardness grades explained
Data from this web page.
La durezza di una matita è data dal tipo di mina, la sua anima in grafite, che ne influenza lo spessore e il colore del tratto. Una matita con mina più dura presenterà un tratto più chiaro e sottile, ma anche più difficile da cancellare, mentre una mina più tenera offrirà un tratto spesso e scuro, più facile da cancellare, ma si consumerà anche più in fretta. Esistono 2 tipi di scale per misurare la durezza di una matita, la scala britannica che utilizza le lettere e quella statunitense che utilizza invece i numeri. Nella tabella qui sotto si possono trovare entrambe le scale con alcune indicazioni sugli utilizzi più idonei.
=== 2+| Grado durezza .2+| Caratteristiche .2+| Utilizzo | Britannico | Statunitense | 9B | .5+| Molto morbide, tratto nero .5+| Lavori artistici quali schizzi e bozze | 8B | | 7B | | 6B | | 5B | | 4B | .4+| Abbastanza morbide, tratto nero .4+| Adatte al disegno a mano libera | 3B | | 2B | #0 | B | #1 | HB | #2 .2+| Durezza media, tratto scuro .2+| Piuttosto versatili, adatte alla scrittura | F | #21/2 | H | #3 .2+| Mina dura, tratto grigio .2+| Indicate per il disegno tecnico | 2H | #4 | 3H | .3+| Piuttosto dure, tratto chiaro .3+| Idonea per progettazioni tecniche o grafiche a livelli avanzati | 4H | | 5H | | 6H | .4+| Molto dure e con tratto molto chiaro .4+| Utilizzate per lavori di litografia, cartografia e xilografia | 7H | 8H | 9H
La lettera H indica le mine più dure (hard) mentre la lettera B indica quelle più morbide (black, ad indicare il tratto più scuro). La lettera F (fine point) invece indica una via di mezzo, né troppo dura né troppo morbida, che, insieme alla HB, via di mezzo leggermente più morbida, è quella più indicata per l’utilizzo nelle scuole. |
