14 <description>&lt;p&gt;Three years ago, the first Norwegian Bokmål edition of
15 &quot;&lt;a href=&quot;https://debian-handbook.info/&quot;&gt;The Debian Administrator&#39;s
16 Handbook&lt;/a&gt;&quot; was published. This was based on Debian Jessie. Now a
17 new and updated version based on Buster is getting ready. Work on the
18 updated Norwegian Bokmål edition has been going on for a few months
19 now, and yesterday, we reached the first mile stone, with 100% of the
20 texts being translated. A lot of proof reading remains, of course,
21 but a major step towards a new edition has been taken.&lt;/p&gt;
22
23 &lt;p&gt;The book is translated by volunteers, and we would love to get some
24 help with the proof reading. The translation uses
25 &lt;a href=&quot;https://hosted.weblate.org/languages/nb_NO/debian-handbook/&quot;&gt;the
26 hosted Weblate service&lt;/a&gt;, and we welcome everyone to have a look and
27 submit improvements and suggestions. There is also a proof readers
28 PDF available on request, get in touch if you want to help out that
29 way.&lt;/p&gt;

38 <title>Secure Socket API - a simple and powerful approach for TLS support in software</title>

42 <description>&lt;p&gt;As a member of the &lt;a href=&quot;https://www.nuug.no/&quot;&gt;Norwegian Unix
43 User Group&lt;/a&gt;, I have the pleasure of receiving the
44 &lt;a href=&quot;https://www.usenix.org/&quot;&gt;USENIX&lt;/a&gt; magazine
45 &lt;a href=&quot;https://www.usenix.org/publications/login/&quot;&gt;;login:&lt;/a&gt;
46 several times a year. I rarely have time to read all the articles,
47 but try to at least skim through them all as there is a lot of nice
48 knowledge passed on there. I even carry the latest issue with me most
49 of the time to try to get through all the articles when I have a few
50 spare minutes.&lt;/p&gt;
51
52 &lt;p&gt;The other day I came across a nice article titled
53 &quot;&lt;a href=&quot;https://www.usenix.org/publications/login/winter2018/oneill&quot;&gt;The
54 Secure Socket API: TLS as an Operating System Service&lt;/a&gt;&quot; with a
55 marvellous idea I hope can make it all the way into the POSIX standard.
56 The idea is as simple as it is powerful. By introducing a new
57 socket() option IPPROTO_TLS to use TLS, and a system wide service to
58 handle setting up TLS connections, one both make it trivial to add TLS
59 support to any program currently using the POSIX socket API, and gain
60 system wide control over certificates, TLS versions and encryption
61 systems used. Instead of doing this:&lt;/p&gt;
62
63 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
64 int socket = socket(PF_INET, SOCK_STREAM, IPPROTO_TCP);
65 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
66
67 &lt;p&gt;the program code would be doing this:&lt;p&gt;
68
69 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
70 int socket = socket(PF_INET, SOCK_STREAM, IPPROTO_TLS);
71 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
72
73 &lt;p&gt;According to the ;login: article, converting a C program to use TLS
74 would normally modify only 5-10 lines in the code, which is amazing
75 when compared to using for example the OpenSSL API.&lt;/p&gt;
76
77 &lt;p&gt;The project has set up the
78 &lt;a href=&quot;https://securesocketapi.org/&quot;&gt;https://securesocketapi.org/&lt;/a&gt;
79 web site to spread the idea, and the code for a kernel module and the
80 associated system daemon is available from two github repositories:
81 &lt;a href=&quot;https://github.com/markoneill/ssa&quot;&gt;ssa&lt;/a&gt; and
82 &lt;a href=&quot;https://github.com/markoneill/ssa-daemon&quot;&gt;ssa-daemon&lt;/a&gt;.
83 Unfortunately there is no explicit license information with the code,
84 so its copyright status is unclear. A
85 &lt;a href=&quot;https://github.com/markoneill/ssa/issues/2&quot;&gt;request to solve
86 this&lt;/a&gt; about it has been unsolved since 2018-08-17.&lt;/p&gt;
87
88 &lt;p&gt;I love the idea of extending socket() to gain TLS support, and
89 understand why it is an advantage to implement this as a kernel module
90 and system wide service daemon, but can not help to think that it
91 would be a lot easier to get projects to move to this way of setting
92 up TLS if it was done with a user space approach where programs
93 wanting to use this API approach could just link with a wrapper
94 library.&lt;/p&gt;
95
96 &lt;p&gt;I recommend you check out this simple and powerful approach to more
97 secure network connections. :)&lt;/p&gt;

106 <title>Bompenge-Norge, med noen tall fra bompengekalkulator</title>
107 <link>http://people.skolelinux.org/pere/blog/Bompenge_Norge__med_noen_tall_fra_bompengekalkulator.html</link>
108 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Bompenge_Norge__med_noen_tall_fra_bompengekalkulator.html</guid>
109 <pubDate>Mon, 1 Jun 2020 14:50:00 +0200</pubDate>
110 <description>&lt;p&gt;Det er tett med sensorstasjoner langs veinettet i Norge, som
111 registrerer hvilke kjøretøy som passerer eller tar bilde av de som
112 drar forbi. I følge
113 &lt;a href=&quot;https://vegkart.atlas.vegvesen.no/&quot;&gt;Vegvesenets nasjonale
114 veidatabank (NVDB)&lt;/a&gt;, er det 353 bomstasjoner langs det norske
115 veinettet. 21 i nordnorge, 48 i trøndelagsområdet, 13
116 nordvestlandet, 91 i bergenstraktene og 180 på østlandsområdet. I
117 tillegg finnes det et utall overvåkningskamera og noen titalls
118 RFID-avlesere for bompengebrikker som samler inn informasjon om hvilke
119 biler som befinner seg hvor i landet. For ikke å glemme alle
120 mobilbasestasjoner som registrerer hvor brukere av mobilnettverket
121 befinner seg. De er ikke tema i dag.&lt;/p&gt;
122
123 &lt;p&gt;De som kjører mye har interesse av å vite hvor mye bompenger det vil
124 koste å kjøre fra et sted til et annet, og dette behovet har aktørene
125 bak &lt;a href=&quot;https://bompengekalkulator.no/&quot;&gt;Bompengekalkulatoren&lt;/a&gt;
126 tatt sikte på å tilby i markedet. Fornuftig nok har de også en
127 gratistjeneste, slik at de får frivillige til å gi innspill om feil i
128 datagrunnlaget. Jeg ble nylig nysgjerring på hvor mye det til koste å
129 kjøre på kryss og tvers i Norge, og valgte meg ut en teststrekning fra
130 Oslo til Tromsø for å se hvilke beløp som gjelder.&lt;/p&gt;
131
132 &lt;p&gt;Bompengekalkulatoren viser frem flere rutealternativer for et gitt
133 reisesøk, og i dette tilfellet, for reise fra Oslo Sentralstasjon til
134 Tromsø sentrum, viser den tre alternativ. Merk, disse tallene gjelder
135 bensindrevet personbil. En kan velge takstkategori i
136 webgrensesnittet. Det ene rutealternativet er E6 gjennom Norge, de to
137 andre er E45 og E4 gjennom sverige. E45 er innlandsruten i Sverige,
138 motorvei gjennom store skoger som i følge kalkulatoren skal ta 22
139 timer og 26 minutter med norsk bompengebeløp på 164 kroner. Jeg har
140 mine tvil til om datasettet til Bompengekalkulatoren har svenske
141 bomstasjoner, så ta dette beløpet med en klype salt. E4 er veien
142 langs Bottenviken og mer befolket område, og skal ta 22 timer og 50
143 minutter til en norsk bompengebeløp på 71 kroner. Den norske ruten
144 langs E6 skal derimot ta 23 timer og 16 minutter og beløpe seg til 664
145 kroner. Beløpene er uten autopass-brikke, slik at en slipper å få
146 bilens posisjon registrert i alle bompengebrikkeavleserne som ikke
147 også er bomstasjoner. For trailere er bompengekostnaden 2-3 ganger så
148 høy som for personbil. I tillegg til pengebeløpet, som faktureres
149 etterskuddsvis og de siste årene har blitt umulig å gjøre opp kontant
150 på stedet, så kommer kostnaden med å få sine personopplysninger samlet
151 inn, lagret og gjort tilgjengelig for fremmede på ubestemt tid. Jeg
152 ser på den kostnaden som mye høyere en pengebeløpet som
153 faktureres.&lt;/p&gt;
154
155 &lt;p&gt;For en tilsvarende tur fra Oslo til Bergen, så forteller
156 kalkulatoren at raskeste vei er riksvei 77 timer 4 minutter med
157 bompengebeløp 409 kroner. Alternativene listet opp er E134 på 8 timer
158 37 minutter med bompengebeløp 318 kroner og fylkesivei 407 timer
159 30 minutter med beløp 331. Det kan kanskje være greit å sjekke ut før
160 en setter seg i bilen hvor ens personopplysninger vil bli samlet inn
161 og lagret 5 fem år, når en velger hvilken rute en går for.&lt;/p&gt;
162
163 &lt;p&gt;Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til
164 det jeg driver med, setter jeg pris på om du sender Bitcoin-donasjoner
165 til min adresse
166 &lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.
167 Merk, betaling med bitcoin er ikke anonymt. :)&lt;/p&gt;

172 <title>More reliable vlc bittorrent plugin in Debian (version 2.9)</title>
173 <link>http://people.skolelinux.org/pere/blog/More_reliable_vlc_bittorrent_plugin_in_Debian__version_2_9_.html</link>
174 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/More_reliable_vlc_bittorrent_plugin_in_Debian__version_2_9_.html</guid>
175 <pubDate>Sun, 24 May 2020 17:00:00 +0200</pubDate>
176 <description>&lt;p&gt;I am very happy to report that a more reliable
177 &lt;a href=&quot;https://tracker.debian.org/pkg/vlc-plugin-bittorrent&quot;&gt;VLC
178 bittorrent plugin&lt;/a&gt; was just uploaded into debian. This fixes a
179 couple of crash bugs in the plugin, hopefully making the VLC
180 experience even better when streaming directly from a bittorrent
181 source. The package is currently in Debian unstable, but should be
182 available in Debian testing in two days. To test it, simply install
183 it like this:&lt;/p&gt;
184
185 &lt;p&gt;&lt;pre&gt;
186 apt install vlc-plugin-bittorrent
187 &lt;/pre&gt;&lt;/p&gt;
188
189 &lt;p&gt;After it is installed, you can try to use it to play a file
190 downloaded live via bittorrent like this:
191
192 &lt;p&gt;&lt;pre&gt;
193 vlc https://archive.org/download/Glass_201703/Glass_201703_archive.torrent
194 &lt;/pre&gt;&lt;/p&gt;
195
196 &lt;p&gt;It also support magnet links and local .torrent files.&lt;/p&gt;
197
198 &lt;p&gt;As usual, if you use Bitcoin and want to show your support of my
199 activities, please send Bitcoin donations to my address

205 <title>Debian Edu interview: Yvan Masson</title>
206 <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Yvan_Masson.html</link>
207 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Yvan_Masson.html</guid>
208 <pubDate>Tue, 12 May 2020 06:30:00 +0200</pubDate>
209 <description>&lt;p&gt;It has been way too long since my last interview, but as the
210 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;
211 community is still active, and new people keep showing up on the IRC
212 channel &lt;a href=&quot;irc://irc.debian.org/#debian-edu&quot;&gt;#debian-edu&lt;/a&gt; and
213 &lt;a href=&quot;https://lists.debian.org/debian-edu/&quot;&gt;the debian-edu mailing
214 list&lt;/a&gt;, I decided to give it another go. I was hoping someone else
215 might pick up the idea and run with it, but this has not happened as
216 far as I can tell, so here we are… This time the announcement of a new
217 free software tool to
218 &lt;a href=&quot;https://framagit.org/Yvan-Masson/WhosWho&quot;&gt;create a school year
219 book&lt;/a&gt; triggered my interest, and I decided to learn more about its
220 author.&lt;/p&gt;
221
222 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
223
224 &lt;p&gt;My name is Yvan MASSON, I live in France. I have my own one person
225 business in computer services. The work consist of visiting my
226 customers (person&#39;s home, local authority, small business) to give
227 advise, install computers and software, fix issues, and provide
228 computing usage training. I spend the rest of my time enjoying my
229 family and promoting free software.&lt;/p&gt;
230
231 &lt;p&gt;&lt;strong&gt;What is your approach for promoting free
232 software?&lt;/strong&gt;&lt;/p&gt;
233
234 &lt;p&gt;When I think that free software could be suitable for someone, I
235 explain what it is, with simple words, give a few known examples, and
236 explain that while there is no fee it is a viable alternative in many
237 situations. Most people are receptive when you explain how it is
238 better (I simplify arguments here, I know that it is not so simple):
239 Linux works on older hardware, there are no viruses, and the software
240 can be audited to ensure user is not spied upon. I think the most
241 important is to keep a clear but moderated speech: when you try to
242 convince too much, people feel attacked and stop listening.&lt;/p&gt;
243
244 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
245 project?&lt;/strong&gt;&lt;/p&gt;
246
247 &lt;p&gt;I can not remember how I first heard of Skolelinux / Debian Edu,
248 but probably on planet.debian.org. As I have been working for a
249 school, I have interest in this type of project.
250
251 &lt;p&gt;The school I am involved in is a school for &quot;children&quot; between 14
252 and 18 years old. The French government has recommended free software
253 since 2012, but they do not always use free software themselves. The
254 school computers are still using the Windows operating system, but all
255 of them have the classic set of free software: Firefox ESR,
256 LibreOffice (with the excellent extension Grammalecte that indicates
257 French grammatical errors), SumatraPDF, Audacity, 7zip, KeePass2, VLC,
258 GIMP, Inkscape…
259
260 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
261 Edu?&lt;/strong&gt;&lt;/p&gt;
262
263 &lt;p&gt;It is free software! Built on Debian, I am sure that users are not
264 spied upon, and that it can run on low end hardware. This last point
265 is very important, because we really need to improve &quot;green IT&quot;. I do
266 not know enough about Skolelinux / Debian Edu to tell how it is better
267 than another free software solution, but what I like is the &quot;all in
268 one&quot; solution: everything has been thought of and prepared to ease
269 installation and usage.&lt;/p&gt;
270
271 &lt;p&gt;I like Free Software because I hate using something that I can not
272 understand. I do not say that I can understand everything nor that I
273 want to understand everything, but knowing that someone / some company
274 intentionally prevents me from understanding how things work is really
275 unacceptable to me.&lt;/p&gt;
276
277 &lt;p&gt;Secondly, and more importantly, free software is a requirement to
278 prevent abuses regarding human rights and environmental care.
279 Humanity can not rely on tools that are in the hands of small group of
280 people.&lt;/p&gt;
281
282 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
283 Edu?&lt;/strong&gt;&lt;/p&gt;
284
285 &lt;p&gt;Again, I don&#39;t know this project enough. Maybe a dedicated website?
286 Debian wiki works well for documentation, but is not very appealing to
287 someone discovering the project. Also, as Skolelinux / Debian Edu uses
288 OpenLDAP, it probably means that Windows workstations cannot use
289 centralized authentication. Maybe the project could use Samba as an
290 Active Directory domain controller instead, allowing Windows desktop
291 usage when necessary.&lt;/p&gt;
292
293 &lt;p&gt;(Editors note: In fact Windows workstations can
294 &lt;a href=&quot;https://wiki.debian.org/DebianEdu/Documentation/Buster/HowTo/Samba&quot;&gt;use
295 the centralized authentication in a Debian Edu setup&lt;/a&gt;, at least for
296 some versions of Windows, but the fact that this is not well known can
297 be seen as an indication of the need for better documentation and
298 marketing. :)&lt;/p&gt;
299
300 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
301
302 &lt;p&gt;Nothing original: Debian testing/sid with Gnome desktop, Firefox,
303 Thunderbird, LibreOffice…&lt;/p&gt;
304
305 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
306 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
307
308 &lt;p&gt;Every effort to spread free software into schools is important,
309 whatever it is. But I think, at least where I live, that IT
310 professionals maintaining schools networks are still very &quot;Microsoft
311 centric&quot;. Schools will use any working solution, but they need people
312 to install and maintain it. How to make these professionals sensitive
313 about free software and train them with solutions like Debian Edu /
314 Skolelinux is a really good question :-)&lt;/p&gt;

319 <title>Jami as a Zoom client, a trick for password protected rooms...</title>
320 <link>http://people.skolelinux.org/pere/blog/Jami_as_a_Zoom_client__a_trick_for_password_protected_rooms___.html</link>
321 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Jami_as_a_Zoom_client__a_trick_for_password_protected_rooms___.html</guid>
322 <pubDate>Fri, 8 May 2020 13:30:00 +0200</pubDate>
323 <description>&lt;p&gt;Half a year ago,
324 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Jami_Ring__finally_functioning_peer_to_peer_communication_client.html&quot;&gt;I
325 wrote&lt;/a&gt; about &lt;a href=&quot;https://jami.net/&quot;&gt;the Jami communication
326 client&lt;/a&gt;, capable of peer-to-peer encrypted communication. It
327 handle both messages, audio and video. It uses distributed hash
328 tables instead of central infrastructure to connect its users to each
329 other, which in my book is a plus. I mentioned briefly that it could
330 also work as a SIP client, which came in handy when the higher
331 educational sector in Norway started to promote Zoom as its video
332 conferencing solution. I am reluctant to use the official Zoom client
333 software, due to their &lt;a href=&quot;https://zoom.us/terms&quot;&gt;copyright
334 license clauses&lt;/a&gt; prohibiting users to reverse engineer (for example
335 to check the security) and benchmark it, and thus prefer to connect to
336 Zoom meetings with free software clients.&lt;/p&gt;
337
338 &lt;p&gt;Jami worked OK as a SIP client to Zoom as long as there was no
339 password set on the room. The Jami daemon leak memory like crazy
340 (approximately 1 GiB a minute) when I am connected to the video
341 conference, so I had to restart the client every 7-10 minutes, which
342 is not a great. I tried to get other SIP Linux clients to work
343 without success, so I decided I would have to live with this wart
344 until someone managed to fix the leak in the dring code base. But
345 another problem showed up once the rooms were password protected. I
346 could not get my dial tone signaling through from Jami to Zoom, and
347 dial tone signaling is used to enter the password when connecting to
348 Zoom. I tried a lot of different permutations with my Jami and
349 Asterisk setup to try to figure out why the signaling did not get
350 through, only to finally discover that the fundamental problem seem to
351 be that Zoom is simply not able to receive dial tone signaling when
352 connecting via SIP. There seem to be nothing wrong with the Jami and
353 Asterisk end, it is simply broken in the Zoom end. I got help from a
354 very skilled VoIP engineer figuring out this last part. And being a
355 very skilled engineer, he was also able to locate a solution for me.
356 Or to be exact, a workaround that solve my initial problem of
357 connecting to password protected Zoom rooms using Jami.&lt;/p&gt;
358
359 &lt;p&gt;So, how do you do this, I am sure you are wondering by now. The
360 trick is already
361 &lt;a href=&quot;https://support.zoom.us/hc/en-us/articles/202405539-H-323-SIP-Room-Connector-Dial-Strings#sip&quot;&gt;documented
362 from Zoom&lt;/a&gt;, and it is to modify the SIP address to include the room
363 password. What is most surprising about this is that the
364 automatically generated email from Zoom with instructions on how to
365 connect via SIP do not mention this. The SIP address to use normally
366 consist of the room ID (a number), an @ character and the IP address
367 of the Zoom SIP gateway. But Zoom understand a lot more than just the
368 room ID in front of the at sign. The format is &quot;&lt;tt&gt;[Meeting
369 ID].[Password].[Layout].[Host Key]&lt;/tt&gt;&quot;, and you can hear see how you
370 can both enter password, control the layout (full screen, active
371 presence and gallery) and specify the host key to start the meeting.
372 The full SIP address entered into Jami to provide the password will
373 then look like this (all using made up numbers):&lt;/p&gt;
374
375 &lt;p&gt;&lt;blockquote&gt;
376 &lt;tt&gt;sip:657837644.522827@192.168.169.170&lt;/tt&gt;
377 &lt;/blockquote&gt;&lt;/p&gt;
378
379 &lt;p&gt;Now if only jami would reduce its memory usage, I could even
380 recommend this setup to others. :)&lt;/p&gt;

389 <title>GnuCOBOL, a free platform to learn and use COBOL - nice free software</title>
390 <link>http://people.skolelinux.org/pere/blog/GnuCOBOL__a_free_platform_to_learn_and_use_COBOL___nice_free_software.html</link>
391 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/GnuCOBOL__a_free_platform_to_learn_and_use_COBOL___nice_free_software.html</guid>
392 <pubDate>Wed, 29 Apr 2020 13:10:00 +0200</pubDate>
393 <description>&lt;p&gt;The curiosity got the better of me when
394 &lt;a href=&quot;https://developers.slashdot.org/story/20/04/06/1424246/new-jersey-desperately-needs-cobol-programmers&quot;&gt;Slashdot
395 reported&lt;/a&gt; that New Jersey was desperately looking for
396 &lt;a href=&quot;https://en.wikipedia.org/wiki/COBOL&quot;&gt;COBOL&lt;/a&gt; programmers,
397 and a few days later it was reported that
398 &lt;a href=&quot;https://onezero.medium.com/ibm-rallies-cobol-engineers-to-save-overloaded-unemployment-systems-eeadf13eddce&quot;&gt;IBM
399 tried to locate COBOL programmers&lt;/a&gt;.&lt;/p&gt;
400
401 &lt;p&gt;I thus decided to have a look at free software alternatives to
402 learn COBOL, and had the pleasure to find
403 &lt;a href=&quot;https://sourceforge.net/projects/open-cobol/&quot;&gt;GnuCOBOL&lt;/a&gt; was
404 already &lt;a href=&quot;https://tracker.debian.org/pkg/gnucobol&quot;&gt;in
405 Debian&lt;/a&gt;. It used to be called Open Cobol, and is a &quot;compiler&quot;
406 transforming COBOL code to C or C++ before giving it to GCC or Visual
407 Studio to build binaries.&lt;/p&gt;
408
409 &lt;p&gt;I managed to get in touch with upstream, and was impressed with the
410 quick response, and also was happy to see a new Debian maintainer
411 taking over when the original one recently asked to be replaced. A
412 new Debian upload was done as recently as yesterday.&lt;/p&gt;
413
414 &lt;p&gt;Using the Debian package, I was able to follow a simple COBOL
415 introduction and make and run simple COBOL programs. It was fun to
416 learn a new programming language. If you want to test for yourself,
417 &lt;a href=&quot;https://en.wikipedia.org/wiki/GnuCOBOL&quot;&gt;the GnuCOBOL Wikipedia
418 page&lt;/a&gt; have a few simple examples to get you startet.&lt;/p&gt;
419
420 &lt;p&gt;As I do not have much experience with COBOL, I do not know how
421 standard compliant it is, but it claim to pass most tests from COBOL
422 test suite, which sound good to me. It is nice to know it is possible
423 to learn COBOL using software without any usage restrictions, and I am
424 very happy such nice free software project as this is available. If
425 you as me is curious about COBOL, check it out.&lt;/p&gt;

435 <link>http://people.skolelinux.org/pere/blog/Totaloverv_kning_av_innbyggernes_bevegelser___nei_takk_.html</link>
436 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Totaloverv_kning_av_innbyggernes_bevegelser___nei_takk_.html</guid>
437 <pubDate>Thu, 16 Apr 2020 20:30:00 +0200</pubDate>
438 <description>&lt;p&gt;Jeg er blitt spurt hva jeg synes om lansering av smittestopp-appen,
439 overvåkningsløsningen lansert av Folkehelseinstituttet,
440 Simula-senteret og Regjeringen i dag, fulgt av klare trusler fra
441 regjeringen om konsekvenser hvis befolkningen ikke tar den i bruk.
442 Rekker ikke skrive noe fyldig om temaet, men det er klart for meg at
443 den utraderer retten til privatliv samt utgjør en personlig
444 sikkerhetsrisiko for alle som tar den i bruk. Bare det er nok til at
445 det fremstår som en svært dårlig ide å bli med på denne &quot;dugnaden&quot;.
446 Det finnes andre og bedre tilnærminger enn den valgt av FHI. Har de
447 valgt sin tilnærming for å sikre seg nok et datasett i den fremtidige
448 ehelse-portalen? Potensialet for misbruk av informasjon samlet inn av
449 appen er for stort, effekten på neste krise for klar og gevinsten for
450 liten.&lt;/p&gt;
451
452 &lt;p&gt;For å si det med forhenværende leder i Datatilsynet, Georg Apenes,
453 som skrev i en kronikk den gang Datatilsynet vernet
454 privatsfæren at
455 «&lt;a href=&quot;https://www.dagbladet.no/kultur/rent-mel-i-bilen/66333882&quot;&gt;SENTRALT
456 I en liberal forestillingsverden finner vi aksept av borgerens rett
457 til å kunne velge å være i fred; å være u-iakttatt, uregistrert og
458 anonym&lt;/a&gt;». Det er ikke uten grunn han startet kronikken med
459 «Personvern et fremmedord i enkelte av de statsorganene som samler
460 inn, oppbevarer og bruker personopplysninger». Der har nok
461 statsorganene bare blitt dårligere på 13 år.&lt;/p&gt;
462
463 &lt;p&gt;Det er jo også verdt å merke seg at personvernrådet i EU (EDPB)
464 mener smittestopp-appen
465 &lt;a href=&quot;https://nrkbeta.no/2020/04/16/personvernrad-i-eu-mener-norsk-app-bryter-med-viktig-personvernprinsipp/&quot;&gt;opererer
466 i strid med prinsippet om dataminimering&lt;/a&gt;. Også de ser at det
467 finnes mye bedre måter å gjøre dette på.&lt;/p&gt;
468
469
470 &lt;p&gt;Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til
471 det jeg driver med, setter jeg pris på om du sender Bitcoin-donasjoner
472 til min adresse
473 &lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.

479 <title>Ny URL til den frie norske stavekontrollen</title>
480 <link>http://people.skolelinux.org/pere/blog/Ny_URL_til_den_frie_norske_stavekontrollen.html</link>
481 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Ny_URL_til_den_frie_norske_stavekontrollen.html</guid>
482 <pubDate>Sat, 21 Mar 2020 08:00:00 +0100</pubDate>
483 <description>&lt;p&gt;Det er lenge siden jeg har sett på den norske stavekontrollen, sist
484 jeg skrev om temaet var i 2016, og i mellomtiden har nettstedet
485 no.speling.org forsvunnet, og både git-depotet på Alioth og
486 mailman-tjenesten som hadde epostlistene for oversettelser blitt lagt
487 ned. Men bokmål og nynorsk trenger fortsatt stavekontroll, så etter
488 et par purringer fra en som har lyst til å forbedre stavekontrollen
489 har jeg endelig fått lagt ut ny offentlig kopi av git-depotet. Jeg
490 valgte gitlab foran github.. Siste utgave av stavekontrollen kan
491 hentes ned fra
492 &lt;a href=&quot;https://gitlab.com/norwegian-language-tools/spell-norwegian&quot;&gt;https://gitlab.com/norwegian-language-tools/spell-norwegian&lt;/a&gt;.
493 Ingen ny versjon i denne omgang altså, bare et nytt sted å samle
494 forbedringer til den frie norske stavekontrollen. :)

549 &lt;li&gt;Corrected relation keys under
550 https://rel.arkivverket.no/noark5/v5/api/administrasjon/, replacing
551 &#39;administrasjon&#39; with &#39;admin&#39;.&lt;/li&gt;

563 use the &#39;kode&#39; value instead of a SystemID.&lt;/li&gt;
564 &lt;li&gt;Corrected implementation of Part and Sakspart.&lt;/li&gt;
565 &lt;li&gt;Changed instance lists with subtypes (like .../registrering/ and
566 .../mappe/) to include the attributes and _links entries for the
567 subtype in the supertype lists.&lt;/li&gt;
568 &lt;li&gt;Adjusted _links relations to make it possible to figure out the
569 entity of an instance using the self-&gt;href-&gt;relation key lookup
570 method.&lt;/li&gt;
571 &lt;li&gt;Fixed several end points to make sure GET, PUT, POST and DELETE
572 match each other.&lt;/li&gt;
573 &lt;li&gt;Updated DELETE endpoints to work with UUID based entity
574 identifiers.&lt;/li&gt;
575 &lt;li&gt;Restructured code to use more common URL related constants in entry
576 point values and replace @RequestMapping with method specific
577 annotations.&lt;/li&gt;
578 &lt;li&gt;Added first unit test code.&lt;/li&gt;
579 &lt;li&gt;Updated web GUI to work with the updated API.&lt;/li&gt;
580 &lt;li&gt;Changed integer fields, enforce them as numeric.&lt;/li&gt;
581 &lt;li&gt;Rewrote and simplify metadata handling to use common service and
582 controller code instead of duplicating for each type.&lt;/li&gt;
583 &lt;li&gt;Implemented the remaining metadata types.&lt;/li&gt;
584 &lt;li&gt;Changed Country list source from Wikipedia to Debian iso-codes and
585 updated the list of Countries.&lt;/li&gt;
586 &lt;li&gt;Many many corrections and improvements.&lt;/li&gt;
587
588 &lt;/ul&gt;
