3D printer
</a>
33 <p>A few days ago, I was introduces to some students in the robot
34 student assosiation
<a href=
"http://www.robotica.no/">Robotica
35 Osloensis
</a> at the University of Oslo where I work, who planned to
36 get their own
3D printer. They wanted to learn from me based on my
37 work in the area. After having a short lunch meeting with them, I
38 offered them to borrow my reprap kit, as I never had time to complete
39 the build and this seem unlike to change any time soon. I look
40 forward to see how this goes. This monday their volunteer driver
41 picked up my kit and drove it to their lab, and tomorrow I am told the
42 last exam is over so they can start work on getting the
3D printer
45 <p>The robotic group have already build several robots on their own,
46 and seem capable of getting the reprap operational. I really look
47 forward to being able to print all the cool
3D designs published on
48 <a href=
"http://www.thingiverse.com/">Thingiverse
</a>. I even got
49 some
3D scans I got made during Dagen@IFI when one of the groups at
50 the computer science department at the university demonstrated their
51 very cool
3D scanner.

78 oppsummering
</a> rundt datalagringsdirektivet, som jeg videreformidler
81 <p><blockquote><strong>Det pågår i disse dager en intens diskusjon om
82 innføring av Datalagringsdirektivet (
<acronym
83 title=
"Datalagringsdirektivet">DLD
</acronym>) i norsk rett. Kanskje
84 har du gjort deg opp en mening, kanskje er du usikker. I begge
85 tilfeller ber jeg deg lese videre.
</strong></p>
87 <p>Samtlige fagmiljøer, både i Norge og EU, har konkludert med at
88 <acronym title=
"Datalagringsdirektivet">DLD
</acronym> ikke bør
89 innføres på nåværende tidspunkt. Den tekniske kvaliteten på direktivet
90 er dårlig, det griper uforholdsmessig inn i personvernet, det har
91 store mangler og viktige spørsmål som hvem som skal ha tilgang og
92 hvordan data skal lagres er fortsatt uavklart.
</p>
95 <li><a href=

104 <p>Jeg liker å tro at jeg er en hyggelig fyr. Jeg har et rent
105 rulleblad, og med unntak av to fartsbøter har jeg aldri vært en byrde
106 for samfunnet. Det akter jeg å fortsette med. Det er mange som meg,
107 lovlydige, pliktoppfyllende borgere som aldri vil utgjøre en trussel
108 mot noe som helst. Vi synes derfor det er trist og sårende at all vår
109 atferd skal overvåkes døgnkontinuerlig.

</a>, it has become obvious that PayPal, visa and mastercard can
157 not be trusted to handle money transactions.
159 <a href=
"http://webmink.com/2010/12/06/now-accepting-bitcoin/">Simon
160 Phipps on bitcoin
</a> reminded me about a project that a friend of
161 mine mentioned earlier. I decided to follow Simon's example, and get
162 involved with
<a href=
"http://www.bitcoin.org/">BitCoin
</a>. I got
163 some help from my friend to get it all running, and he even handed me
164 some bitcoins to get started. I even donated a few bitcoins to Simon
165 for helping me remember BitCoin.
</p>
167 <p>So, what is bitcoins, you probably wonder? It is a digital
168 crypto-currency, decentralised and handled using peer-to-peer
169 networks. It allows anonymous transactions and prohibits central
170 control over the transactions, making it impossible for governments
171 and companies alike to block donations and other transactions. The
172 source is free software, and while the key dependency wxWidgets
2.9
173 for the graphical user interface is missing in Debian, the command
174 line client builds just fine. Hopefully Jonas
175 <a href=
"http://bugs.debian.org/578157">will get the package into
178 <p>Bitcoins can be converted to other currencies, like USD and EUR.
179 There are
<a href=
"http://www.bitcoin.org/trade">companies accepting
180 bitcoins
</a> when selling services and goods, and there are even
181 currency "stock" markets where the exchange rate is decided. There
182 are not many users so far, but the concept seems promising. If you
183 want to get started and lack a friend with any bitcoins to spare,
185 <a href=
"https://freebitcoins.appspot.com/">some for free
</a> (
0.05
186 bitcoin at the time of writing). Use
187 <a href=
"http://www.bitcoinwatch.com/">BitcoinWatch
</a> to keep an eye
188 on the current exchange rates.
</p>
190 <p>As an experiment, I have decided to set up bitcoind on one of my
191 machines. If you want to support my activity, please send Bitcoin
192 donations to the address

">Some thoughts on BitCoins</a>
256 <p>As I continue to explore
257 <a href="http://www.bitcoin.org/
">BitCoin</a>, I've starting to wonder
258 what properties the system have, and how it will be affected by laws
259 and regulations here in Norway. Here are some random notes.</p>
261 <p>One interesting thing to note is that since the transactions are
262 verified using a peer to peer network, all details about a transaction
263 is known to everyone. This means that if a BitCoin address has been
264 published like I did with mine in my initial post about BitCoin, it is
265 possible for everyone to see how many BitCoins have been transfered to
266 that address. There is even a web service to look at the details for
267 all transactions. There I can see that my address
268 <a href="http://blockexplorer.com/address/

">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a>

1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt
">1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt</A>
273 of EFF have received 2447.38 BitCoins so far. Thank you to each and
274 every one of you that donated bitcoins to support my activity. The
275 fact that anyone can see how much money was transfered to a given
276 address make it more obvious why the BitCoin community recommend to
277 generate and hand out a new address for each transaction. I'm told
278 there is no way to track which addresses belong to a given person or
279 organisation without the person or organisation revealing it
280 themselves, as Simon, EFF and I have done.</p>
282 <p>In Norway, and in most other countries, there are laws and
283 regulations limiting how much money one can transfer across the border
284 without declaring it. There are money laundering, tax and accounting
285 laws and regulations I would expect to apply to the use of BitCoin.
286 If the Skolelinux foundation
287 (<a href="http://linuxiskolen.no/slxdebianlabs/donations.html
">SLX
288 Debian Labs</a>) were to accept donations in BitCoin in addition to
289 normal bank transfers like EFF is doing, how should this be accounted?
290 Given that it is impossible to know if money can across the border or
291 not, should everything or nothing be declared? What exchange rate
292 should be used when calculating taxes? Would receivers have to pay
293 income tax if the foundation were to pay Skolelinux contributors in
294 BitCoin? I have no idea, but it would be interesting to know.</p>
296 <p>For a currency to be useful and successful, it must be trusted and
297 accepted by a lot of users. It must be possible to get easy access to
298 the currency (as a wage or using currency exchanges), and it must be
299 easy to spend it. At the moment BitCoin seem fairly easy to get
300 access to, but there are very few places to spend it. I am not really
301 a regular user of any of the vendor types currently accepting BitCoin,
302 so I wonder when my kind of show would start accepting BitCoins. I
303 would like to buy electronics, travels and subway tickets, not herbs
304 and books. :) The currency is young, and this will improve over time
305 if it become popular, but I suspect regular banks will start to lobby
306 to get BitCoin declared illegal if it become popular. I'm sure they
307 will claim it is helping fund terrorism and money laundering (which
308 probably would be true, as is any currency in existence), but I
309 believe the problems should be solved elsewhere and not by blaming
312 <p>The process of creating new BitCoins is called mining, and it is
313 CPU intensive process that depend on a bit of luck as well (as one is
314 competing against all the other miners currently spending CPU cycles
315 to see which one get the next lump of cash. The "winner" get
50
316 BitCoin when this happen. Yesterday I came across the obvious way to
317 join forces to increase ones changes of getting at least some coins,
318 by coordinating the work on mining BitCoins across several machines
319 and people, and sharing the result if one is lucky and get the
50
321 <a href=

322 if this sounds interesting. I have not had time to try to set up a
323 machine to participate there yet.
