Da han +kom nærmere, kunne jeg se at han kastet sjøstjerner, som var etterlatt +i sanden av tidevannet, tilbake i havet. Da han var nær nok spurte jeg +ham hvorfor han jobbet så hardt på denne merkelige oppgaven. Han sa at +solen snart ville stå opp og tørke sjøstjernene slik at de ville +dø.</p> + +<p>Jeg sa til ham at dette var helt meningsløst. Det var kilometer på +kilometer med strand, og det lå sjøstjerner hele veien. En person +alene kunne ikke gjøre noen forskjell. Han smilte da han plukket opp +neste sjøstjerne. Mens han kastet den så langt ut i havet som han +klarte sa han, «for denne gjør det en forskjell».

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> + + + + + Norwegian movies that might be legal to share on the Internet + http://people.skolelinux.org/pere/blog/Norwegian_movies_that_might_be_legal_to_share_on_the_Internet.html + http://people.skolelinux.org/pere/blog/Norwegian_movies_that_might_be_legal_to_share_on_the_Internet.html + Sun, 1 Sep 2019 11:10:00 +0200 + <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.

To quote Wikipedia: SOSI is short for -Samordnet Opplegg for Stedfestet Informasjon (literally "Coordinated -Approach for Spatial Information", but more commonly expanded in -English to Systematic Organization of Spatial Information). It is a -text based file format for geo-spatial vector information used in -Norway. Information about the SOSI format can be found in English -from <a href="https://en.wikipedia.org/wiki/SOSI">Wikipedia</a>. The -specification is available in Norwegian from -<a href="https://www.kartverket.no/geodataarbeid/Standarder/SOSI/">the -Norwegian mapping authority</a>.

If all goes well, in a few months, anyone implementing -the Noark 5 Tjenestegrensesnitt API spesification should be able to -use an official MIME type and PRONOM code for SOSI files. In -addition, anyone using SOSI files on Linux should be able to -automatically recognise the format and web sites handing out SOSI -files can begin providing a more specific MIME type. So far, SOSI -files has been handed out from web sites using the -"application/octet-stream" MIME type, which is just a nice way of -stating "I do not know". Soon, we will know. :)</p> - -<p>As usual, if you use Bitcoin and want to show your support of my -activities, please send Bitcoin donations to my address -<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p> - - - - - PlantUML for text based UML diagram modelling - nice free software - http://people.skolelinux.org/pere/blog/PlantUML_for_text_based_UML_diagram_modelling___nice_free_software.html - http://people.skolelinux.org/pere/blog/PlantUML_for_text_based_UML_diagram_modelling___nice_free_software.html - Mon, 25 Mar 2019 09:35:00 +0100 - <p>As part of my involvement with the -<a href="https://gitlab.com/OsloMet-ABI/nikita-noark5-core/">Nikita -Noark 5 core project</a>, I have been proposing improvements to the -API specification created by <a href="https://www.arkivverket.no/">The -National Archives of Norway</a> and helped migrating the text from a -version control system unfriendly binary format (docx) to Markdown in -git. Combined with the migration to a public git repository (on -github), this has made it possible for anyone to suggest improvement -to the text.</p> - -<p>The specification is filled with UML diagrams. I believe the -original diagrams were modelled using Sparx Systems Enterprise -Architect, and exported as EMF files for import into docx. This -approach make it very hard to track changes using a version control -system. To improve the situation I have been looking for a good text -based UML format with associated command line free software tools on -Linux and Windows, to allow anyone to send in corrections to the UML -diagrams in the specification. The tool must be text based to work -with git, and command line to be able to run it automatically to -generate the diagram images. Finally, it must be free software to -allow anyone, even those that can not accept a non-free software -license, to contribute.</p> - -<p>I did not know much about free software UML modelling tools when I -started. I have used dia and inkscape for simple modelling in the -past, but neither are available on Windows, as far as I could tell. I -came across a nice -<a href="https://modeling-languages.com/text-uml-tools-complete-list/">list -of text mode uml tools</a>, and tested out a few of the tools listed -there. <a href="http://plantuml.com/">The PlantUML tool</a> seemed -most promising. After verifying that the packages -<a href="https://tracker.debian.org/pkg/plantuml">is available in -Debian</a> and found <a href="https://github.com/plantuml/plantuml">its -Java source</a> under a GPL license on github, I set out to test if it -could represent the diagrams we needed, ie the ones currently in -<a href="https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/">the -Noark 5 Tjenestegrensesnitt specification</a>. I am happy to report -that it could represent them, even thought it have a few warts here -and there.</p> - -<p>After a few days of modelling I completed the task this weekend. A -temporary link to the complete set of diagrams (original and from -PlantUML) is available in -<a href="https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/issues/76">the -github issue discussing the need for a text based UML format</a>, but -please note I lack a sensible tool to convert EMF files to PNGs, so -the "original" rendering is not as good as the original was in the -publised PDF.</p> - -<p>Here is an example UML diagram, showing the core classes for -keeping metadata about archived documents:</p> - -<pre> -@startuml -skinparam classAttributeIconSize 0 - -!include media/uml-class-arkivskaper.iuml -!include media/uml-class-arkiv.iuml -!include media/uml-class-klassifikasjonssystem.iuml -!include media/uml-class-klasse.iuml -!include media/uml-class-arkivdel.iuml -!include media/uml-class-mappe.iuml -!include media/uml-class-merknad.iuml -!include media/uml-class-registrering.iuml -!include media/uml-class-basisregistrering.iuml -!include media/uml-class-dokumentbeskrivelse.iuml -!include media/uml-class-dokumentobjekt.iuml -!include media/uml-class-konvertering.iuml -!include media/uml-datatype-elektronisksignatur.iuml - -Arkivstruktur.Arkivskaper "+arkivskaper 1..*" <-o "+arkiv 0..*" Arkivstruktur.Arkiv -Arkivstruktur.Arkiv o--> "+underarkiv 0..*" Arkivstruktur.Arkiv -Arkivstruktur.Arkiv "+arkiv 1" o--> "+arkivdel 0..*" Arkivstruktur.Arkivdel -Arkivstruktur.Klassifikasjonssystem "+klassifikasjonssystem [0..1]" <--o "+arkivdel 1..*" Arkivstruktur.Arkivdel -Arkivstruktur.Klassifikasjonssystem "+klassifikasjonssystem [0..1]" o--> "+klasse 0..*" Arkivstruktur.Klasse -Arkivstruktur.Arkivdel "+arkivdel 0..1" o--> "+mappe 0..*" Arkivstruktur.Mappe -Arkivstruktur.Arkivdel "+arkivdel 0..1" o--> "+registrering 0..*" Arkivstruktur.Registrering -Arkivstruktur.Klasse "+klasse 0..1" o--> "+mappe 0..*" Arkivstruktur.Mappe -Arkivstruktur.Klasse "+klasse 0..1" o--> "+registrering 0..*" Arkivstruktur.Registrering -Arkivstruktur.Mappe --> "+undermappe 0..*" Arkivstruktur.Mappe -Arkivstruktur.Mappe "+mappe 0..1" o--> "+registrering 0..*" Arkivstruktur.Registrering -Arkivstruktur.Merknad "+merknad 0..*" <--* Arkivstruktur.Mappe -Arkivstruktur.Merknad "+merknad 0..*" <--* Arkivstruktur.Dokumentbeskrivelse -Arkivstruktur.Basisregistrering -|> Arkivstruktur.Registrering -Arkivstruktur.Merknad "+merknad 0..*" <--* Arkivstruktur.Basisregistrering -Arkivstruktur.Registrering "+registrering 1..*" o--> "+dokumentbeskrivelse 0..*" Arkivstruktur.Dokumentbeskrivelse -Arkivstruktur.Dokumentbeskrivelse "+dokumentbeskrivelse 1" o-> "+dokumentobjekt 0..*" Arkivstruktur.Dokumentobjekt -Arkivstruktur.Dokumentobjekt *-> "+konvertering 0..*" Arkivstruktur.Konvertering -Arkivstruktur.ElektroniskSignatur -[hidden]-> Arkivstruktur.Dokumentobjekt -@enduml -</pre> - -<p><a href="http://plantuml.com/class-diagram">The format</a> is quite -compact, with little redundant information. The text expresses -entities and relations, and there is little layout related fluff. One -can reuse content by using include files, allowing for consistent -naming across several diagrams. The include files can be standalone -PlantUML too. Here is the content of -<tt>media/uml-class-arkivskaper.iuml<tt>:</p> - -<pre> -@startuml -class Arkivstruktur.Arkivskaper <Arkivenhet> { - +arkivskaperID : string - +arkivskaperNavn : string - +beskrivelse : string [0..1] -} -@enduml -</pre> - -<p>This is what the complete diagram for the PlantUML notation above -look like:</p> - -<p><img width="80%" src="http://people.skolelinux.org/pere/blog/images/2019-03-25-noark5-plantuml-diagrameksempel.png"></p> - -<p>A cool feature of PlantUML is that the generated PNG files include -the entire original source diagram as text. The source (with include -statements expanded) can be extracted using for example -<tt>exiftool</tt>. Another cool feature is that parts of the entities -can be hidden after inclusion. This allow to use include files with -all attributes listed, even for UML diagrams that should not list any -attributes.</p> - -<p>The diagram also show some of the warts. Some times the layout -engine place text labels on top of each other, and some times it place -the class boxes too close to each other, not leaving room for the -labels on the relationship arrows. The former can be worked around by -placing extra newlines in the labes (ie "\n"). I did not do it here -to be able to demonstrate the issue. I have not found a good way -around the latter, so I normally try to reduce the problem by changing -from vertical to horizontal links to improve the layout.</p> - -<p>All in all, I am quite happy with PlantUML, and very impressed with -how quickly its lead developer responds to questions. So far I got an -answer to my questions in a few hours when I send an email. I -definitely recommend looking at PlantUML if you need to make UML -diagrams. Note, PlantUML can draw a lot more than class relations. -Check out the documention for a complete list. :)</p> - -<p>As usual, if you use Bitcoin and want to show your support of my -activities, please send Bitcoin donations to my address -<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p> - - -
