personal reminder: building debian packages from source

...for future reference:
  1. apt-get source (-t testing) PACKAGENAME
  2. apt-get build-dep (-t testing) PACKAGENAME
  3. cd PACKAGANAME-version
  4. OPT: vi debian/rules (e.g. to activate some experimental features)
  5. OPT: vi debian/patches/00list (to enlist a patch that should be applied)
  6. OPT: vi debian/patches/...

apt-listchanges chokes on its DB (bsddb.db.DBRunRecoveryError)

in case of:
Traceback (most recent call last):File "/usr/bin/apt-listchanges", line 229, in ?main()File "/usr/bin/apt-listchanges", line 150, in mainseen.close()File "bsddb/__init__.py", line 237, in closebsddb.db.DBRunRecoveryError: (-30974, 'DB_RUNRECOVERY: Fatal error, run database recovery -- PANIC: fatal region error detected; run recovery')
(similarly to the post below) something along the lines of:
cd /var/lib/aptdb4.6_dump listchanges.db | db4.3_load temp.dbmv temp.db listchanges.db

Psychology of Scales

The machine that will solve all the mysteries in science was inaugurated.The Cern is there, up and running.You may ask a question about the nature of the universe.The New York times informs that the particle collisions that will answer that question require about 5 trillion electron-Volt. 5 Trillion.Now. As a mechanical engineer I had to make the conversion to a unit that makes more sense to me. Like the Watt/second (W/s), or Joule.5 10^12 / 1.6 10^-19 = 3.125.10^-7 JThat is, not that much energy, in fact.

Super Track! Ich wuerde auch ganz gerne mit einer solchen Stimme singen koennen. Doch leider schrottet man sich derbe die Stimmbaender wenn man das uebt….

How many spikes in a J

A do-it-yourself experiment:Question: How many action potentials (spikes) fit in a 'j'?Step 1. Type the 'j' key (any key will do, really, just as long it produces a character. Shift, for example, does not), with one finger, in the editor of your choice, in intervals of t seconds, in this case t=4s.Do it as fast as you can. (It is in principle not necessary. But in that case, in the end of the calculation you find the minimum number of spikes per jay.

Mihai Eminescu - Dorința

Vino-n codru la izvorul Care tremură pe prund, Unde prispa cea de brazde Crengi plecate o ascund. Şi în braţele-mi întinse Să alergi, pe piept să-mi cazi, Să-ţi desprind din creştet vălul, Să-l ridic de pe obraz. Pe genunchii mei şedea-vei, Vom fi singuri-singurei, Iar în păr înfiorate Or să-ţi cadă flori de tei. Fruntea albă-n părul galben Pe-al meu braţ încet s-o culci, Lăsând pradă gurii mele Ale tale buze dulci… Vom visa un vis ferice, Îngâna-ne-vor c-un cânt Singuratece izvoare, Blânda batere de vânt; Adormind de armonia Codrului bătut de gânduri, Flori de tei deasupra noastră
