Lehekülje Ruby lähteteksti vaatamine

===Sissejuhatus===

===Tööpõhimõte===

Väited

* Ruby on virtuaalne arvuti - st ruby runtime tegeleb bytecode, mäluhalduse, scheduling jms ülesannetega - selles runtime'is käititatakse ruby keeles programmeeritud tegevused
* TODO

Populaarsed ruby failinimede lõpud

* .rb - ruby source code jms
* .rake - ruby maitseline Makefile
* .gemspec - paketihaldusega seotud fail
* .rdoc ja .ri - dokumentatsioon

Käesolev tekst tegeleb muu hulgas kahe teemaga

* ruby enda keskkonna paigaldamine - seejuures viisil, et kasutamisel saab valida erinevate ruby versioonide vahel
* ruby keskkonda tarkvara paigaldamine gem kujul - seejuures saab paigaldada sama tarkvara erinevaid versioone

===Ruby paigaldamine tavakasutaja osakonda===

Käesoleval juhul paigaldatakse Ruby lahendus tavakasutajana, alustatatakse süsteemi ettevalmistamisest

<pre>
root@ubuntu-2604-01:~# apt-get install build-essential autoconf libssl-dev libyaml-dev zlib1g-dev libffi-dev libgmp-dev rustc
</pre>

kus

* c kompilaator on vajalik c xxx 

Otsustatakse hallata erinevaid ruby keskkondi rbenv lahenduse abil

TODO

===Gem turvalisus===

Väited

* iseensest gem formaat ja käsitlus jne võimaldab signeeritud viisil toimetamist
* gem signeeritumist praktiliselt ei kasutata - nt https://rubygems.org/ ei ole gemid signeeritud
* gem puhul on siiski kasutusel räsid
* st gem pidamine ei ole kaitstud sellise turvalisusega nagu nt apt repode kasutamine
* gem signeerimine sarnaneb rpm lähenemisele mõttes, et signeeritakse üksikut pakette mitte pakettide komplekti (nagu apt puhul)

====Kasulikud lisamaterjalid====

* https://rubygems.org/
* https://guides.rubygems.org/security/

===Signeeritud gem moodustamine===
