  32         <p>At work, we have a few hundred Linux servers, and with that amount
  33 of hardware it is important to keep track of when the hardware support
  34 contract expire for each server.  We have a machine (and service)
  35 register, which until recently did not contain much useful besides the
  36 machine room location and contact information for the system owner for
  37 each machine.  To make it easier for us to track support contract
  38 status, I've recently spent time on extending the machine register to
  39 include information about when the support contract expire, and to tag
  40 machines with expired contracts to make it easy to get a list of such
  41 machines.  I extended a perl script already being used to import
  42 information about machines into the register, to also do some screen
  43 scraping off the sites of Dell, HP and IBM (our majority of machines
  44 are from these vendors), and automatically check the support status
  45 for the relevant machines.  This make the support status information
  46 easily available and I hope it will make it easier for the computer
  47 owner to know when to get new hardware or renew the support contract.
  48 The result of this work documented that 27% of the machines in the
  49 registry is without a support contract, and made it very easy to find
  50 them.  27% might seem like a lot, but I see it more as the case of us
  51 using machines a bit longer than the 3 years a normal support contract
  52 last, to have test machines and a platform for less important
  53 services.  After all, the machines without a contract are working fine
  54 at the moment and the lack of contract is only a problem if any of
  55 them break down.  When that happen, we can either fix it using spare
  56 parts from other machines or move the service to another old
  57 machine.</p>
  58
  59 <p>I believe the code for screen scraping the Dell site was originally
  60 written by Trond Hasle Amundsen, and later adjusted by me and Morten
  61 Werner Forsbring.  The HP scraping was written by me after reading a
  62 nice article in ;login: about how to use WWW::Mechanize, and the IBM
  63 scraping was written by me based on the Dell code.  I know the HTML
  64 parsing could be done using nice libraries, but did not want to
  65 introduce more dependencies.  This is the current incarnation:</p>

 173 <p>Here are some examples on how to use the function, using fake

 178 print get_support_info("hp.host", "HP ProLiant BL460c G1", "1234567890"
 179                        "447707-B21");
 180 print get_support_info("dell.host", "Dell Inc. PowerEdge 2950", "1234567");
 181 print get_support_info("ibm.host", "IBM eserver xSeries 345 -[867061X]-",
 182                        "1234567");
 183 </pre>
 184
 185 <p>I would recommend this approach for tracking support contracts for
 186 everyone with more than a few computers to administer. :)</p>
 187
 188 <p>Update 2009-03-06: The IBM page do not include extended support
 189 contracts, so it is useless in that case.  The original Dell code do
 190 not handle extended support contracts either, but has been updated to
 191 do so.</p>

 212         <p>At work with the University of Oslo, we have several hundred computers
 213 in our computing center.  This give us a challenge in tracking the
 214 location and cabling of the computers, when they are added, moved and
 215 removed.  Some times the location register is not updated when a
 216 computer is inserted or moved and we then have to search the room for
 217 the "missing" computer.</p>
 218
 219 <p>In the last issue of Linux Journal, I came across a project
 220 <a href="http://www.libdmtx.org/">libdmtx</a> to write and read bar
 221 code blocks as defined in the
 222 <a href="http://en.wikipedia.org/wiki/Data_Matrix">The Data Matrix
 223 Standard</a>.  This is bar codes that can be read with a normal
 224 digital camera, for example that on a cell phone, and several such bar
 225 codes can be read by libdmtx from one picture.  The bar code standard
 226 allow up to 2 KiB to be written in the tag.  There is another project
 227 with <a href="http://www.terryburton.co.uk/barcodewriter/">a bar code
 228 writer written in postscript</a> capable of creating such bar codes,
 229 but this was the first time I found a tool to read these bar
 230 codes.</p>
 231
 232 <p>It occurred to me that this could be used to tag and track the
 233 machines in our computing center.  If both racks and computers are
 234 tagged this way, we can use a picture of the rack and all its
 235 computers to detect the rack location of any computer in that rack.
 236 If we do this regularly for the entire room, we will find all
 237 locations, and can detect movements and removals.</p>
 238
 239 <p>I decided to test if this would work in practice, and picked a
 240 random rack and tagged all the machines with their names.  Next, I
 241 took pictures with my digital camera, and gave the dmtxread program
 242 these JPEG pictures to see how many tags it could read.  This worked
 243 fairly well.  If the pictures was well focused and not taken from the
 244 side, all tags in the image could be read.  Because of limited space
 245 between the racks, I was unable to get a good picture of the entire
 246 rack, but could without problem read all tags from a picture covering
 247 about half the rack.  I had to limit the search time used by dmtxread
 248 to 60000 ms to make sure it terminated in a reasonable time frame.</p>
 249
 250 <p>My conclusion is that this could work, and we should probably look
 251 at adjusting our computer tagging procedures to use bar codes for
 252 easier automatic tracking of computers.</p>

 273         <p>I regi av
 274 <a href="http://www.personvern.no/">personvernforeningen</a> har jeg
 275 startet på
 276 <a href="http://personvern.no/wiki/index.php/Kameraovervåkning">et
 277 kart over overvåkningskamera i Norge</a>.  Bakgrunnen er at det etter
 278 min mening bærer galt avsted med den massive overvåkningen som
 279 finner sted i Norge i dag, og at flere og flere overvåkningskamera
 280 gjør det vanskeligere og vanskeligere å gå igjennom livet uten at
 281 små og store brødre trenger inn i ens private sfære.  Datatilsynet
 282 har et register over kameraovervåkning, men det viser seg å være
 283 ubrukelig både til å finne ut hvor det er kamera plassert, og til å
 284 sjekke om et kamera en kommer over er registrert.  Dette nye kartet
 285 fikser en av disse manglene, men det vil fortsatt være umulig å vite
 286 om et kamera er registrert etter lovens krav eller ikke.  Pr. nå er
 287 22 kamera i Oslo registrert, og det trengs flere til å registrere
 288 alle.  Informasjonen registreres direkte inn i <a
 289 href="http://www.openstreetmap.org/">OpenStreetmap</a>, så hentes det
 290 automatisk over i spesialkartet.</p>

 373         <p>Min reprap begynner å ta form.  Den er nå kommet så langt at den er
 374 blitt en kubisk ramme.  Z-aksen er montert men ikke kalibrert, og det
 375 hele er klart for litt enkel testing.  Har møtt på to problemer som
 376 blokkerer videre montering, men har oppnått kontakt med Audun Vaaler
 377 ved Høgskolen i Østfold som forteller at de er nesten ferdig med et
 378 tilsvarende byggesett som det jeg tar utgangspunkt i, og håper de kan
 379 forklare hvordan de kom rundt problemene.  De to problemene er
 380 relatert til Z-aksen og Y-aksen.  </p>
 381
 382 <p>For Z-aksen, er det et stjernehjul som festes på motoraksen ved
 383 tannjulet som driver z-aksebåndet og som skal holde båndet på plass.
 384 Problemet med det nederste stjernejulet er at det er helt løst, og
 385 blir liggende på motoren 5 mm nedenfor tannjulet, i stedet for å ligge
 386 inntil tannjulet slik det skal.  Mulig løsningen er å borre i
 387 stjernehjulet, eller lime det fast.</p>
 388
 389 <p>For Y-aksen, er det en plastdel som ser ut til å mangle som skulle
 390 dekket to skruver som kommer i veien for kraftoverføringsmekanismen
 391 fra motoren til selve aksen, slik at mekanismen kan snurre fritt.</p>
 392
 393 <p>Når det gjelder elektronikken til min reprap, så er min gode venn
 394 Anders Rosnes igang med å lodde sammen delene og han forteller at
 395 koblingsbordet for Arduino er klart, og en temperatursensor og en
 396 optoswitch er også klar.  Gleder meg til å teste dem.  Må bare finne
 397 ut hvordan jeg laster opp firmware i Arduino-en. :)</p>
 398
 399 <p>Når det gjelder NUUGs reprap-prosjekt, så er det framgang og Ole
 400 Kristian, Tollef og Ketil besøke IFI for å få fortgang i produksjon av
 401 plastdeler, og Ole Kristian forteller at han har funnet en kilde til
 402 de fleste metalldelene.  Gleder meg til å se resultaten av det
 403 arbeidet.</p>

 424         <p>De siste årene har jeg forsøkt å få liv i
 425 <a href="http://www.personvern.no/">foreningen Personvern i Norge</a>.  Norge
 426 trenger en organisasjon som jobber med å sette personvern på agendaen
 427 og som kan være en motvekt til de mange som gjerne raderer bort
 428 personvernet av behagelighetshensyn eller ut fra villfarelsen om at en
 429 får økt sikkerhet av å redusere personvernet.  Foreløbig har det ikke
 430 lykkes å få på plass kritisk masse av interesserte på epostlisten, og
 431 nå tror jeg det er på tide å endre tilnærming.  I stedet for å forsøke
 432 å rekruttere folk til epostlisten og håpe at når nok folk er samlet
 433 vil noen ta initiativ og sørge for at det begynner å skje ting, så
 434 tror jeg det er en ide å ta utgangspunkt i de som er der i dag og
 435 sette sammen et interrimstyre.  Forslaget er sendt til epostlisten, så
 436 nå får vi se om noen er enig.</p>

 457         <p>Ofte brukes intellektuell eiendom som samlebegrep for opphavsrett,
 458 patenter, varemerker og forretningshemmeligheter.  Problemet med dette
 459 begrepet er at det er svært misvisende.  For det første er ingen av de
 460 begrensede monopolene det her er snakk om som kan kalles eiendom, og
 461 for det andre er egenskapene til de ulike monopolene så forskjellige
 462 at det er mer tilslørende enn opplysende å gruppere dem sammen i et
 463 sekkebegrep.  Blant annet Richard Stallman har
 464 <a href="http://www.gnu.org/philosophy/not-ipr.html">skrevet litt om dette</a>.</p>
 465
 466 <p>I dag kom jeg over
 467 <a href="http://blogs.sun.com/webmink/entry/intellectual_privilege">en
 468 bloggpost fra Simon Phipps</a> som foreslår å bruke intellektuelt
 469 privilegium som begrep i stedet, da det gjør det klarere at det ikke
 470 er snakk om eiendom, men et tidsbegrenset monopol.  Simon Phipps
 471 forteller videre at noen jobber med å skrive
 472 <a href="http://www.intellectualprivilege.com/book.html">en bok med
 473 tittel Intellectual Privilege</a>, og at boken er anbefalt av Lawrence
 474 Lessig.  Jeg tror jeg skal begynne å bruke begrepet intellektuelt
 475 privilegium når jeg snakker om opphavsrett, patenter, varemerker og
 476 forretningshemmeligheter framover.</p>
