Erinnert ihr euch an die „Switch“-Kampagne von Apple damals? apple.com/switch – Das gleiche passiert jetzt wieder, aber in die andere Richtung: Switch to Linux!

Ja, ich habe es getan. Schon vor ein paar Monaten. Ich brach aus dem Apfelparadiesgarten aus und bin komplett auf GNU/Linux umgestiegen. Davon geträumt habe ich schon immer, aber immer wieder gab es Dinge, die mich an Mac OS X fesselten. Exposé. Videobearbeitung. iTunes und mein iPod. Vorschau.app. Funktionierendes Bluetooth und VPN mit einem Klick aus der Menüleiste aus. Mail.app. Mit Ctrl und dem Scrollrad in den Bildschirm hineinzoomen. Oder mit zwei Fingern auf dem Touchpad scrollen.
Kleine Dinge. Aber sie funktionieren, und das eben gut. Dieses Edel-Unix kommt von einem Hersteller aus einem Guss, und es funktioniert wunderbar. Die Funktionen und die Art, es zu bedienen, waren anderen immer ein paar Schritte voraus.

Und dann kamen Dinge, die mir immer mehr auf den Sack gingen:

• Apple macht Exposé kaputt
• Das Durchsuchen von E-Mails dauert lang oder funktioniert gar nicht (meine Mailbox hat >20’000 E-Mails – und ja, ich bewahre alle meine Mails auf, aber bei mir zuhause und nicht in einer Wolke)
• Scrollen im iPhoto ist dermassen ruckelig und schrottig; da sieht man mehr Beachbälle als Fotos. Allgemein bei vielen Programmen, z.b wenn iTunes den iPod synchronisiert.
• Die Icons im Finder waren mal farbig und schön. Apple malt alle grau und monoton an. Igitt. Und ich kann absolut nichts dagegen tun – ich bin den Entscheidungen von Apple einfach nur unterworfen!

Während dieser Zeit passierten noch andere Dinge:

• Richard Stallman hält einen Vortrag an der ETH und inspiriert mich mit seiner Philosophie von freier Software
• Ich schaue beim CCC Zürich im Hackerspace vorbei und treffe auf liebe Menschen, die sich mit Linux gut auskennen und mir helfen können.

Was mir endgültig den Gong gegeben hat, ist das:

• Betriebssystemupdates gibt’s nur noch via App-Store
• Bei dem muss man seine Kreditkarte hinterlegen, auch wenn man nie was kaufen wird
• Das Betriebssystem wird nicht mehr auf CD ausgeliefert
• Keine Schachtel mehr, die ich stolz ins Regal stellen kann (Jaa, ich bin war so ein Apple-Jünger!)
• Das neue Macbook Pro hat aufgelöteten RAM, eingeklebte Akkus und ein SSD mit proprietärer Schnittstelle
• Jedes neue Modell hat einen neuen Stromstecker
• Die neuen Macbooks haben keinen Ethernet-Anschluss. Dazu bräuchte man einen Adapter
• Ein DVD-Laufwerk fehlt
• Die Benutzeroberfläche ist uneinheitlich. Das ist nicht mehr aus einem Guss!
• Facebook ist im OS integriert

Weisst du was, Apple? FUCK OFF.

Es mag sein, dass alles ein perfekt aufeinander abgestimmtes Ökosystem ist, das in sich wunderbar funktioniert. Aber ich bin dem komplett ausgeliefert und unterworfen. Das passt mir nicht!

Ich wechsle auf freie Software; nicht nur serverseitig, sondern jetzt auch clientseitig. Ich verzichte auf all den Komfort, die schönen Schriftarten und tolle Typographie und die (paar wenigen) gutaussehenden Programme. Natürlich ist es aufwändig, sich sein eigenes System zusammenzustellen, bis alles so funktioniert wie man möchte. Aber DAS ist dann mein System, wo keine Firma einen Furz ablässt und ich es einatmen muss. Ich kann es nach belieben anpassen und verändern. Die Farben, das Aussehen, alles. Oder es so lassen, wie es ist, und es bleibt so.

Ich habe mich aus den Klauen von Betriebssystemherstellerfirmen befreit.

Man wechselt nicht zu Linux wegen des Komforts. Sondern aus einer Ideologie. Die Ideologie einer Freiheit; dass jeder Software verwenden kann, die von niemandem kontrolliert wird, sondern von tausenden Menschen um den Planeten freiwillig erstellt wird. Und man selber etwas dazu beitragen kann, wenn man möchte. Das hat was anarchistisches, da ist eine Gemeinschaft dahinter. Wir schreiben unsere eigene Software! Selber machen ist toll.

Dieses Konzept gefällt mir sehr, und hat mich schlussendlich zu diesem Schritt bewogen, und mir die Energie gegeben, die ich für so einen Umstieg brauchte. Bequemlichkeit und Komfort sind eine Falle, welche ohne eine Ideologie viel zu leicht zuschnappt.

Viele Web- und Proxyserver bringen eine Loadbalancerfunktion mit. Mit Session-Stickyness. „Hach wie praktisch“, könnte man denken. Leider funktioniert das nicht immer so wie es im Handbuch steht.

Wir kommen in Frieden, sagten die Eroberer der neuen Welt.
Wir kommen in Frieden, sagt die Regierung, wenn es darum geht, die neue digitale Welt zu kolonisieren, zu regulieren, zu militarisieren.
Wir kommen in Frieden, sagen die Grosskonzerne, wenn sie losziehen und das Netz monetarisieren und die Benutzer an ihre glitzernden neuen Geräte binden.
Wir kommen in Frieden, sagen wir als Hacker, Geeks und Nerds, wenn wir losziehen in die echte Welt, und sie ändern wollen, weil jemand unser natürliches Habitat bedroht, den Cyberspace.

• Ich will jemandem ein vertrauliches, d.h. verschlüsseltes E-Mail schreiben
• Der Empfänger stellt sein öffentlicher Schlüssel zur Verfügung, mit dem ich meine Nachricht für ihn verschlüsseln kann
• Entschlüsseln kann sie nur der Empfänger, und zwar mit seinem privaten Schlüssel
• Öffentliche Schlüssel werden auf Verzeichnissen publiziert
• Problem: Jemand kann unter dem gleichen Namen des Empfängers einen Schlüssel ins Verzeichnis stellen und sich als Empfänger ausgeben

Wie stellen wir sicher, dass der Empfänger auch wirklich derjenige ist, als den er sich ausgibt? Ich habe nicht mit ihm persönlich Schlüssel getauscht.

Lösung: Über ein Web of Trust; einen Vertrauenspfad.

Sehenswerte Unterhaltung mit Linus Torvalds; hier in voller Länge.

I like offending people, because I think people who get offended should be offended.
-Linus Torvalds

One difference I’ve noticed between great hackers and smart people in general is that hackers are more politically incorrect.

GEILGEILGEIL
WENN?

gömmer anes public view vo dere schlüsselnotiz und sprütze uns gegesittig in grind? 😀 😀

i bi so gottefroh chani das alles lo tschättere loh.

es muess mi nid ufrege,
wenn apple s ganz GUI vom OS wiX so usgseh loht als wär mi mac e telefon. si häns no NIE gschafft e einheitlichi benutzeroberflächi us eim guss z präsentiere. irgendnöime isch immer no irgend e chnöpfli gsi, wo nid so usgseht oder sich nid so verhaltet wie dr räscht.

s muess mi nid störe,
wenn si facebook fescht ins OS ibaue (WTF?)

i bi nid ane app-store bunde,
wome kreditkarte muess ha, au wemme nie öbbis chaufe wird. i cha wähle zwüsche ganz vielne app-stores (aka „repositories“, und sowas gits bi uns scho sit tag 1).
oder i mach grad mis eigene repo.

all dene änderige bini nüm usglieferet. denn ich bestimm, was uf miner chischte lauft, vo wäm, und wie’s usgseht und funktioniert.
ich bestimm, wo mini date gspeicheret wärde und wie. nämlich verschlüsslet und bi mir deheim.

apropos telefon.
das böxli mag sehr nätt si, aber es sammlet date über di und dini ufenthaltsort, damit all die tolle sache funktioniere. und du weisch nid was alles für date, wie s das macht und wo s das speicheret; ES IST GESCHLOSSEN und proprietär.

mini hardware isch überall kompatibel, und wenn nid, schribt sicher irgendöbber uf dr wält e triibe derzue <3

SCHLOH MI AB, PEITSCH MI US! I VERZICHT UF SCHÖNI Typ0GRAPHiE UND UF GUETUSSEHENDI APPS…
…im Austausch für meine Freiheit.

Ich habe ein neues Spielzeug: Puppet.

Puppet, an automated administrative engine for your *nix systems, performs administrative tasks (such as adding users, installing packages, and updating server configurations) based on a centralized specification.

Wie oft musste ich Server einrichten, Apaches konfigurieren und dergleichen. Nach dem x-ten mal kommt zwar eine gewisse Routine auf. Aber dann ändert etwas; einem Apache muss ein Varnish-Cache vornedran gestellt werden – hmm. Was muss ich jetzt schon wieder alles anpassen? Ports der VirtualHosts, der Listen Port… Ganz gewiss geht was vergessen, und erst nach dem 3. mal Dienste neustarten und ausprobieren funktioniert alles.

Das ist jetzt Vergangenheit. [mehr…]

Kunde möchte eine voraussichtlich stark frequentierte Seite mit Typo3 bei sich hosten. 
Erwartet werden 5000 Benutzer gleichzeitig – die geschätzt alle 10 Sekunden klicken. Ergibt 500 Requests/s. Wir sollen die Architektur vorschlagen.

Mein Metier. Nach einer zweiwöchigen Evaluation kristallisierte sich Nginx mit FastCGI als Webserver heraus, weil der FastCGI Anfragen cachen kann und somit auf eine tolle Geschwindigkeit kommt.

Das Problem ist nicht der Cache an sich. Das Problem ist, wie Nginx damit umgeht, wenn der Cache verfällt.

Der Cache hat ein Ablaufdatum, eine Time-To-Live, TTL. Läuft diese ab, muss das HTML vom Backend neu geholt werden. Und wenn der Cache bei 500 gleichzeitigen Anfragen pro Sekunde abläuft, muss das HTML 500 mal gleichzeitig vom Backend geholt werden. Schönä!
