HOW TO Transform A SERVER APPLICATION TO A “Micro serie”

HOW TO CONTAINERIZED

1. decompose and make it for each component
2. All and decompose

Why

1. OS/ infrastructure indipendend
2. Sw indipendend (e.g. Packet of OS)
3. Improve with spaghetti code

Weakness of start with this code:

• Code not for container
• External tools ( coupled with system, not like REST api)
• Hostname → Dns not of all
• Timezone

Tool windup → Analizza vulnerabilità

Start after test

→ Then PODMAN cointain with systemd

Tool for install and migrate → Check start status → Then can proceed

→ Important for show status at user and help him

Laboratorio integrazione in SPARQL su Wikidata

Wikidata → For keep one source right for all wiki (e.g. for each language)

→ Structured data:

• Soggetto
• Predicato
• Valore (oggetto) ( + origine, e.g. Rivisto, governo | + history )

Query

SparQl → select ?value where { ?subject ?Predicate ?Value }

Output

• Table
• Gallery
• Time “string”
• Map

e.g. People born in a city that make something in life

SELECT ?person ?personLabel
WHERE {
  ?person wdt:P19 wd:Q490.
  ?person wdt:P31 wd:Q5.
  SERVICE wikibase:label { bd:serviceParam wikibase:language "it". }
}

Come RUST semplifica l’open source

Cargo: Packet manager (TOML)

• Build
• Run ( == execute + Build)

Create auto the docs of personal and dependancy methods (for offline)

Cargo Semver changes → Check API Breaking changes

rMarkdown un’interfaccia notebook per la

R:

• Funzione statico
• Report riproducibilità
• Slide da HTML5
• R-base R-base-dev (dependency)

BuocManaged

Site: BroConductor

Donald Knuth → TeX Inventor

Octabe → Matlab clone opensource

rMarkdown → Like Jupyter

Boodown.org/yihui/rmarkdown

Rstudio → Desktop and server } versione

Package Leaf let → Mappa

Pacman → Check library exists
