- <title>What would it cost to store all 2018 phone calls in Norway?</title>

- <description><p>Four years ago, I did a back of the envelope calculation on
-<a href="http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html">how
-much it would cost to store audio recordings of all the phone calls in
-Norway</a>, and came up with NOK 2.1 million / EUR 250 000 for the
-year 2013. It is time to repeat the calculation using updated
-numbers. The calculation is based on how much data storage is needed
-for each minute of audio, how many minutes all the calls in Norway
-sums up to, multiplied by the cost of data storage.</p>
-
-<p>The number of phone call minutes for 2018 was fetched from
-<a href="https://ekomstatistikken.nkom.no/">the NKOM statistics
-site</a>, and for 2018, land line calls are listed as 434 238 000
-minutes, while mobile phone calls are listed with 7 542 006 000
-minutes. The total number of minutes is thus 7 976 244 000. For
-simplicity, I decided to ignore any advantages in audio compression the
-last four years, and continue to assume 60 Kbytes/min as the last
-time.</p>
-
-<p>Storage prices still varies a lot, but as last time, I decide to
-take a reasonable big and cheap hard drive, and double its price to
-include the surrounding costs into account. A 10 TB disk cost less
-than 4500 NOK / 450 EUR these days, and doubling it give 9000 NOK per
-10 TB.</p>
-
-<p>So, with the parameters in place, lets update the old table
-estimating cost for calls in a given year:</p>
-
-<table border="1">
-<tr><th>Year</th><th>Call minutes</th><th>Size</th><th>Price in NOK / EUR</th></tr>
-<tr><td>2005</td><td align="right">24 000 000 000</td><td align="right">1.3 PiB</td><td align="right">1 170 000 / 117 000</td></tr>
-
-<tr><td>2012</td><td align="right">18 000 000 000</td><td align="right">1.0 PiB</td><td align="right">900 000 / 90 000</td></tr>
-
-<tr><td>2013</td><td align="right">17 000 000 000</td><td align="right">950 TiB</td><td align="right">855 000 / 85 500</td></tr>
-
-<tr><td>2018</td><td align="right">7 976 244 000</td><td align="right">445 TiB</td><td align="right">401 100 / 40 110</td></tr>
-</table>
-
-<p>Both the cost of storage and the number of phone call minutes have
-dropped since the last time, bringing the cost down to a level where I
-guess even small organizations can afford to store the audio recording
-from every phone call taken in a year in Norway. Of course, this is
-just the cost of buying the storage equipment. Maintenance, need to
-be included as well, but the volume of a single year is about a single
-rack of hard drives, so it is not much more than I could fit in my own
-home. Wonder how much the electricity bill would raise if I had that
-kind of storage? I doubt it would be more than a few tens of thousand
-NOK per year.</p>

- <title>Norwegian movies that might be legal to share on the Internet</title>

- <description><p>While working on identifying and counting movies that can be
-legally shared on the Internet, I also looked at the Norwegian movies
-listed in IMDb. So far I have identified 54 candidates published
-before 1940 that might no longer be protected by norwegian copyright
-law. Of these, only 29 are available at least in part from the
-Norwegian National Library. It can be assumed that the remaining 25
-movies are lost. It seem most useful to identify the copyright status
-of movies that are not lost. To verify that the movie is really no
-longer protected, one need to verify the list of copyright holders and
-figure out if and when they died. I've been able to identify some of
-them, but for some it is hard to figure out when they died.</p>
-
-</p>This is the list of 29 movies both available from the library and
-possibly no longer protected by copyright law. The year range
-(1909-1979 on the first line) is year of publication and last year
-with copyright protection.</p>

-To be sure which one of these can be legally shared on the Internet,
-in addition to verifying the right holders list is complete, one need
-to verify the death year of these persons:

-<p>Several of these movies completely lack right holder information in
-IMDb and elsewhere. Without access to a copy of the movie, it is
-often impossible to get the list of people involved in making the
-movie, making it impossible to figure out the correct copyright
-status.</p>
-
-<p>Not listed here are the movies still protected by copyright law.
-Their copyright terms varies from 79 to 144 years, according to the
-information I have available so far. One of the non-lost movies might
-change status next year,
-<a href="https://www.imdb.com/title/tt1008007/">Mustads Mono from 1920</a>.
-The next one might be
-<a href="https://www.imdb.com/title/tt0347215/">Hvor isbjørnen ferdes
-from 1935</a> in 2024.</p>
