Weekly hours of television and internet consumption in Norway 1991-2018

A couple of days ago, I blogged about time spent watching television and video by different age groups in Norway. Of course the issue of internet immediately popped up, so I made this graph showing both time spent watching television and time spent on the internet:

With regards to total screen time, note that these graphs leave out time spent watching video tapes and dvds and time spent on computers, electronic games and mobile phones without using the internet.


Time spent watching TV and video media in Norway 1991-2018

Inspired by a tweet by Gray Kimbrough graphing changes in television and video watching in the US between the mid-2000s and the mid-2010s for various age groups, I decided to follow up with a similar figure with Norwegian data. Gray showed that in the US, people aged 45 and older increased their watching substantially, while younger people decreased it at least to some extent. In Norway the picture was somewhat different – there was very little change for the oldest groups, but the youngest ones reduced their watching by much more than in the US.

Part of the reason for making the graph was to learn how to use the pcarrow option in Stata, which I accomplished, however, I found that in this case with only five groups, a simple line chart may actually provide more information and be preferable:

How does the Heartbleed bug work?

The Heartbleed bug is everywhere, so it is nice to understand it a little. xkcd has drawn it, but a few words might help to interpret his comic. The “heartbeat” option allows a computer to check that it still has a connection to a server. The computer sends a message, for example “asdfgh” that the server repeats back to acknowledge that it is there. Now, the bug allows tricking the server by telling it that the message sent is much longer than it really is, for example saying that the message “asdfgh” is 64 000 characters. Then the server does not stop after “asdfgh,” but continues with further 63 994 characters from its memory. Since many people use one server, these extra characters may contain usernames and passwords that other people have entered. The heart bleeds.

The benefits of a surveillance state

Surveillance gets a bad rap these days, but here is another perspective, stated clearly for once: Stuart Armstrong writing in the Aeon magazine spells out what the benefits of total surveillance might be.  Summary: less crime, fewer resources spent on police and military, prevent pandemics and terrorists, help disaster response, provide data for research, practical applications, more global trust. (And he duly notes: “these potential benefits aren’t the whole story on mass surveillance.”)

How the decentralization of technology work against a “surveillance state dystopia”

The coming of a sureveillance state dystopia has been predicted for some time. Ramez Naam writes a guest post at Charles Stross’ blog, and claims that the decentralization of technology has been responsible for the postponement. E.g., getting away with photoshopping images is a lot harder today than in Stalin’s time.

Naam spells out three technological trends that will help the little man even further: 1. Cheap cameras for self-protection. “[Camera] technology, when expensive benefits the big players. The technology getting cheaper becomes distributed, benefiting the citizenry.” “2. Crypto and Anonymity Blunt Surveillance Tools.” If someone is not looking for you in particular, anonomity tools are quite effective. 3. Information is becoming easier to spread. Naam ends by emphasizing that these trends will be no panacea, we will still need the law and proper oversight.
