ruby::na::rails

i am currently developing an iphone client application for the social networking site called koornk.

working with xcode and apple tools in general makes me think, all this fancy stuff coming from apple is just a peace of fancy stuff.

we should have robust application development environments since ever, but I am just a slave, poor little freelancer, trying to keep up with all this fancy stuff.

I think programming in general needs to develop higher. I think we need to start thinking about the possibilites of programming our lives. with simple straight forward thinking. creating thoughts of beneficience for humanity and we could finally reach the stars we left behind billions of ages ago.

technology will unite the world, there is no doubt about it, but i think all this new age technology is just another blindfold for the masses.

hočeš narediti rails aplikacijo, ki bi bila sposobna obstajati na različnih domenah, ki si jih uporabniki sami zberejo. ali pa bi vsak uporabnik imel svojo subdomeno. recimo.

tedaj si je dobro pripraviti svoj lepi OS, da ti pomaga, za dober začetek, pri testiranju.

ker jaz ne bi za vsak testni primer delal zapiskov v /etc/hosts.

s takšnim zapiskom v /etc/hosts, bi lahko probaval samo 3 različne sajte na localhostu.

127.0.0.1 friend.fromhell.local
127.0.0.1 friend.justone.local
127.0.0.1 truper.fromhell.local

ne pa tudi tiste, ki bi si jih lahko kar sproti izmišljeval. recimo tulili.tulele.rails, potem pa recimo heh.eh.rails. hočem svobodo odločanja.

zato je mnogo bolje, če se pozanimam na google in naredim nekaj resnega. kot je na primer: local name server.

to sem naredil, potem sem naredil pa tole (na OSX Leopard):

kmak:~> $ sudo -s
bash-3.2# rndc-confgen > /etc/rndc.conf
bash-3.2# head -n5 /etc/rndc.conf |tail -n4 > /etc/rndc.key
bash-3.2# mate /etc/named.conf

na tem mestu sem v fajl named.conf pred “logging” zadegal tole:

zone "rails" IN {
    type master;
    file "rails.zone";
    allow-update { none; };
};

in to je zdaj naša zona. ali tisti string, ki je na koncu urlja. sedaj morem še povedat nekomu, da naj tole upošteva. v ta namen sem naredil še tole:

bash-3.2# cd /var/named/
bash-3.2# cp localhost.zone rails.zone
bash-3.2# mate rails.zone

v tem fajlu sem le preimenoval eno pojavitev niza localhost v niz rails. tam pri ORIGIN. potem pa dodal zadnjo vrstico.

$TTL    86400
$ORIGIN rails.
@            1D IN SOA    @ root (
                    42        ; serial (d. adams)
                    3H        ; refresh
                    15M        ; retry
                    1W        ; expiry
                    1D )        ; minimum

            1D IN NS    @
            1D IN A        127.0.0.1

* IN A 127.0.0.1

zadnja vrstica nazorno prikaže, da bodo vsi dostopi do domen z obliko subdomena.domena.rails, preusmerjeni na localhost. hehe.

dalje, priročno uporabim program, ki dela čudeže, a ima neizgovorljivo ime : launchctl.

bash-3.2# launchctl load -w /System/Library/LaunchDaemons/org.isc.named.plist
bash-3.2# exit

sedaj bo OSX vedno nalagal tole zadevo, tudi ko reštartam.

edino, in res zadnje, ostane, da za vsako TCP/IP povezavo dodaš DNS server z naslednjo IP

127.0.0.1

ja res.

to lahko narediš, če greš na črno japko, pa na System Preferences, pa na Network. in tam greš čez željene povezave in nastaviš pod DNS.

ta članek sem radostno povzel po setting up local name server on mac os x.

meni je delalo takoj. naj še tebi.
