Jak bezpiecznie być w chmurze

W nawiązaniu do poprzedniego wpisu - poradnik praktyczny, w jaki sposób mieć dane w chmurze a jednocześnie pozostać bezpiecznym. Założenia - mamy wiele komputerów (np w domu, w pracy, u starych) na każdym chcemy mieć pewien zbiór plików, np tych z którymi pracujemy. No to wiadomo dropbox. Ale np wiemy, że w pracy administrator ma dostęp do wszystkich komputerów. Stąd zaprzęgamy do roboty jeszcze truecrypta. Na każdym z komputerów tworzymy szyfrowany wolumen dropboxa (powiedzmy 10GB) w którym trzymać będziemy synchronizowane pliki. Na wolumenie dwa katalogi: Dropbox oraz DanePoczty (dałem po polsku bo niektórzy mogliby nie zrozumieć). Katalog drugi nie jest synchronizowany (po co, skoro poczta jest na IMAP). Uwaga, dwa założenia: 1. ufamy dropboxowi, jeśli ktoś trzyma rzeczy których się boi lub sądzi że goście z dropboxa czytają jego listy do lasek to musi postawić swój synchronizator (np na rsync) 2. poczta jest na imap - czyli ufamy dostawcy poczty. Jeśli ktoś nie ufa, bla bla, czytaj pkt pierwszy. System działa idealnie - czyli chroni nasze dane przed innymi userami, którzy mają dostęp do naszych sprzętów :)

If I could offer you only one tip for the future, sunscreen would be IT. (...) Don't worry about the future; or worry, but know that worrying is as effective as trying to solve an algebra equation by chewing bubblegum. The real troubles in your life are apt to be things that never crossed your worried mind; the kind that blindside you at 4pm on some idle Tuesday. Do one thing every day that scares you. Don't waste your time on jealousy; sometimes you're ahead, sometimes you're behind. The race is long, and in the end, it's only with yourself. (...) Stretch. Don't feel guilty if you don't know what you want to do with your life. The most interesting people I know didn't know at 22 what they wanted to do with their lives, some of the most interesting 40 year olds I know still don't. Get plenty of calcium. (...) Maybe you'll marry, maybe you won't, maybe you'll have children, maybe you won't, maybe you'll divorce at 40, maybe you'll dance the funky chicken on your 75th wedding anniversary. Whatever you do, don't congratulate yourself too much or berate yourself, either. Your choices are half chance, so are everybody else's. (...) Dance. Even if you have nowhere to do it but in your own living room. Read the directions, even if you don't follow them. (...) Understand that friends come and go, but for the precious few you should hold on. (...) Travel. Accept certain inalienable truths, prices will rise, politicians will philander, you too will get old, and when you do you'll fantasize that when you were young prices were reasonable, politicians were noble and children respected their elders. (...) Be careful whose advice you buy, but, be patient with those who supply it. Advice is a form of nostalgia, dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it's worth. But trust me on the sunscreen. (Mary Schmich, Chicago Tribune / Baz Luhrmann)
