1. Find the masking tape, and tear off a long enough strip to hold the ColorHug on the monitor. This is probably the real reason I gave up last time; it takes about 45minutes to run the calibration, and I lack the attention span/upper-arm-strength to hold the sensor up for that long. Apparently new ColorHugs are shipping with some elastic.
2. Update the firmware on the colorhug. This is a gui-wizard kindof thing.

    % apt-get install colorhug-client
    % colorhug-flash 
   

3. Set the monitor to factory defaults. On this ASUS PA238QR, that is brightness 100, contrast 80, R=G=B=100. I adjusted the brightness down to about 70; 100 is kindof eye-burning IMHO.
4. Figure out which display is which; I have two monitors.

    % dispwin -\?
   

   Look under "-d n"
5. Do the calibration. This is really verbatim from Pascal, except I added the ENABLE_COLORHUG=true and -d 2 bits.

    % apt-get install argyll
    % ENABLE_COLORHUG=true dispcal -v -d 2 -m -q m -y l -t 6500 -g 2.2 test
    % targen -v -d 3 -G -f 128 test
    % ENABLE_COLORHUG=true dispread -v -d 2 -y l -k test.cal test
    % colprof -v -A "make" -M "model" -D "make model desc" -C   "copyright" -q m -a G test
   

6. Load the profile

    % dispwin -d 2 -I test.icc           
   

   It seems this only loads the x property _ICC_PROFILE_1 instead of _ICC_PROFILE; whether this works for a particular application seems to be not 100% guaranteed. It seems ok for darktable and gimp.

• Last year delegation for Google Summer of Code Admins 1 has expired and the program for 2013 will likely start soon. I'm looking for volunteer admins for this year, to organize Debian activities in the program. If you're interested, please contact me.
• In January we had a couple of related discussions on -project about DFSG 10 and maintaining an authoritative list of DFSG-free licenses. The latter would be an important contribution to the Free Software "political" ecosystem. An ikiwiki-based infrastructure to maintain such a list has been created by ftp-masters but needs to be populated. At this point we need volunteers willing to review licenses already present in main and fill them in. If you're interested, please review the discussion and manifest yourself on debian-dak@lists.d.o, where coordination about this work will happen.

• The long standing issue of writing a proper (outbound) trademark policy for Debian marks has been completed. I've reviewed on -project outstanding items from the last discussion, and documented how they've been implemented in a new policy draft. Later on, I've published the updated policy draft on our website.
• Complementary to the above, Ian Jackson has summarized the state of the discussion about our (inbound) trademark policy, i.e. what to do when accepting in the Debian archive software subject to trademark. It looks like we are close to conclusion on that front too.
• I've worked with representatives of Debian France, on the shared interest in having the association become a Debian Trusted Organization (per Constitution 9.3). We're not yet ready to start the 2 weeks discussion period to accept the orga as such (see Constitution 5.1.11), but I'd like to do that soon. So I encourage all of you to find out about the association, which is run by well-known project members.

• Usually try to stick to the upstream version if it is sane. (With the exception of data based versions, as experience shows upstreams later change their mind, so a version of 20130210 is best translated to 0.20130210 in order to have a future 1.0 sort higher).
• If there are some suffixes in the version that denote a "before", prefix them with a tilde.
• Compare a version to your last version and put zeros or .0 at the end (or the ends of parts) where necessary to increase them.

• You want to package 2.0 but you need to repack the .orig.tar because it contains a file with some non-free license (for example no license at all). Then you can call it 2.0~dfsg-1. If the file is later relicensed, you can do a 2.0-2 with the original file which sorts higher.
• You need to repack 2.0 but it was already in the archive. then you can do 2.0+dfsg-1 as this is higher. (using the plus has the advantage that you can later use the 2.0.0 trick if the file is relicensed, while the older 2.0.dfsg-1 made this impossible). (One can also use -dfsg-1 here, but + might be easier to parse for humans).
• You package a git snaphost of a version 2.0 not yet released, then you can use 2.0~gitXYZ-1
• You package a git snapshot of upstream doing some works on top of 1.9, then you can use 1.9+gitXYZ-1

Edward Tufte s Speech From Aaron Swartz s Memorial
Speech starts 41:00 [video cuts out in beginning]
We would then meet over the years for a long talk every now and then, and my responsibility was to provide him with a reading list, a reading list for life and then about two years ago Quinn had Aaron come to Connecticut and he told me about the four and a half million downloads of scholarly articles and my first question is, Why isn t MIT celebrating this? .
[Video cuts out again]
Obviously helpful in my career there, he then became president of the Mellon foundation, he then retired from the Mellon foundation, but he was asked by the Mellon foundation to handle the problem of JSTOR and Aaron. So I wrote Bill Bullen(sp?) an email about it, I said first that Aaron was a treasure and then I told a personal story about how I had done some illegal hacking and been caught at it and what happened. In 1962, my housemate and I invented the first blue box, that s a device that allows for free, undetectable, unbillable long distance telephone calls. And we got this up and played around with it and the end of our research came when we concluded what was the longest long distance call ever made, which was from Palo Alto to New York time-of-day via Hawaii, well during our experimentation, AT&T, on the second day it turned out, had tapped our phone and uh but it wasn t until about 6 months later when I got a call from the gentleman, AJ Dodge, senior security person at AT&T and I said, I know what you re calling about. and so we met and he said You what you are doing is a crime that would , you know all that. But I knew it wasn t serious because he actually cared about the kind of engineering stuff and complained that the tone signals we were generating were not the standard because they record them and play them back in the network to see what numbers they we were that you were trying to reach, but they couldn t break though the noise of our signal. The upshot of it was that uh oh and he asked why we went off the air after about 3 months, because this was to make long distance telephone calls for free and I said this was because we regarded it as an engineering problem and we made the longest long distance call and so that was it. So the deal was, as I explained in my email to Bill Bullen, that we wouldn t try to sell this and we were told, I was told that crime significance would pay a great deal for this, we wouldn t do any more of it and that we would turn our equipment over to AT&T, and so they got a complete vacuum tube isolator kit for making long distance phone calls. But I was grateful for AJ Dodge and I must say, AT&T that they decided not to wreck my life. And so I told Bill Bullen that he had a great opportunity here, to not wreck somebody s life, course he thankfully did the right thing.
Aaron s unique quality was that he was marvelously and vigorously different. There is a scarcity of that. Perhaps we can be all a little more different too.
Thank you very much.

• We recommend that people from nearby countries take advantage of the excellent train connections to Switzerland, rather than looking for flights: the Swiss Federal Railways website, provides a very helpful international travel planner which knows about trains, but also about the local bus connections you will need to reach the DebConf venue.
• The best railway station to aim for is Yverdon-les-Bains. To get to the venue from there, take a local bus to the bus stop called Concise, Camp de Vaumarcus , which is very close to the venue. You can also directly use that name as your final destination in the above travel planner.
• Nearby airports include Geneva - GVA (1h30 from the venue by train), Zurich - ZRH (3h from the venue by train) and Basel-Mulhouse - BSL (3h from the venue by train).
