I all things that can be logged and automated. For a while I have been monitoring the inside and outside temperature at home, at work and at the cottage.

A few weeks ago, I showed a colleague of mine my temperature graphs. She is no stranger of logging, and showed me a bunch of graphs from her weather station. It was pretty obvious what would happen: I just had to get a weather station. With a bunch of sensors, there would be endless possibilities of logging 🙂 As I live in an apartment in Oslo, it is placed at hour cottage. We have mobile broadband there, so I can still get live data. Actually, the weather station is attached to the mobile broadband antenna we already had.

Yesterday I got a note from the post office that told me that a package could be picked up.  I could see that the package was from China, but that was all.  I buy all kinds of stuff from China that costs a few bucks, so this could be anything.  When these packages arrive three weeks later, I have often forgotten about it.  So what could this be?  This was kind of like  Christmas 🙂

As a hobby photographer using Linux, I have been quite frustrated with the color profiles of my screens. More than once, I have adjusted the colors of an image manually, only to be surprised when I get a print back and the image is way too red. Last week a ColorHug arrived at my post office, the solution to all my color frustrations.

I dag kjøpte jeg enda et spill fra Steam: The Secret of Monkey Island, dvs. ikke den gamle, men den oppussede utgaven.

As I wrote in my last post, I had finally got my Raspberry Pi. Now I needed to install some software.

The first time I read about Raspberry Pi, I thought: I got to get one of these! Now I have finally got one.

Jeg husker for en ti års tid siden (eller var det litt mer) da mediene skrev mye om cookies og hvordan vi ble overvåket osv. Det er jo ikke så vanskelig å slette cookies, så om man skulle ønske å ikke bli gjenkjent på en side man har vært før så var det ikke så vanskelig.

Men så kom jeg over Evercookies. Kort fortalt er det et javscriptbibliotek som bruker alle mulige skitne triks i ludo for å se om du har vært på siden tidligere. Selvsagt benyttes vanlige cookies, men det er flere triks som kan benyttes:

  • Standard HTTP Cookies
  • Local Shared Objects (Flash Cookies)
  • Storing cookies in RGB values of auto-generated, force-PNGs using HTML5
  • Canvas tag to read pixels (cookies) back out
  • Storing cookies in Web History (seriously. see FAQ)
  • HTML5 Session Storage
  • HTML5 Local Storage
  • HTML5 Global Storage
  • HTML5 Database Storage via SQLite

Dette er jo litt artige saker. HTML5 krever jo en nettleser av litt nyere dato, men sitter vi ikke alle på en slik snart? 😉

Jeg bet meg merke i “Storing cookies in Web History” og måtte sjekke linken som var vedlagt. Kort fortalt er det mulig å sjekke med javascript om du har besøkt en eller flere sider i en definert liste. Dette kan brukes for å lagre cookies (sjekk forklaringen på siden).

Men man kan like gjerne bruke trikset for å sjekke om du har besøkt ett eller flere domener i en liste over domener. Resultatet kan igjen sendes tilbake til server uten at du merker det. Artige saker, men ikke helt bra. Du kan teste effekten (som benytter CSS for å sjekke besøkstatusen) på denne siden.

Ikke så rart at de fleste nettleserne har implementert “private browsing” kanskje 🙂

Jeg for min del fikk vite at jeg en gang i historien har besøkt perezhilton.com.  Det kan jeg virkelig ikke erindre (hva i huleste gjorde jeg der?), mumle mumle.
