My open source disaster recovery strategy for the home office

Person using a laptop
I've worked from home for years, and with the COVID-19 crisis, millions more have joined me. Teachers, accountants, librarians, stockbrokers… you name it, these workers now operate full or part time from their homes. Even after the coronavirus crisis ends, many will continue working at home, at least part time. But what happens when the home worker's computer fails? Whether the device is a smartphone, tablet, laptop, or desktop—and whether the problem is hardware or software—the result might be missed workdays and lots of frustration.

The 2020 CC Global Summit Keynotes Are Here!

We have exciting news…we published the keynotes from the 2020 CC Global Summit!

In addition to the 170+ sessions hosted at last year’s virtual event, we hosted three keynotes that helped us think through how to connect the events of 2020 with our work—and find a path forward in hope and optimism. We’re excited to share these recordings of the keynotes with you today!
A Culture of Peace

This keynote featured Bushra Ebadi (Canadian Commission for UNESCO), Deepak Ramola (Project FUEL), Leonardo Párraga (Juventudes Por La Paz), and Asha Siad (Memories of Mogadishu). It fostered a necessary discussion on the role “open” plays in advancing peace, challenging the audience to critically examine preconceived notions of open access, open culture, and open knowledge, and to understand the role decolonized and democratized conceptions of these terms will serve in building the future we want. For more on this keynote, check out this Twitter thread!

Hacer Feminista Lo Abierto: Poniendo Nuevos Engranes a La Cultura Libre

This keynote featured Irene Soria (CC Mexico). Given in Spanish, it set the stage for exploring new definitions of “open.” Using intersectionality as a framing, Irene helped us navigate the relationships between race, gender, and social class as new ways of seeing the open movement. For more on this keynote, check out this Twitter thread!

Democracy for Sale

This keynote featured Catherine Stihler (CC CEO) and Alek Tarkowski (CC Board Member) speaking with Peter Geoghegan (author of Democracy for Sale). They discussed the links between fighting for our democracies and fighting for “open” and the public interest. For more on this keynote, check out this Twitter thread!

What’s next?

We’re still working on receiving permission from the speakers to publicly release all of the CC Global Summit video recordings. Once that process is completed, we’ll start creating a catalog on the CC Global Summit website of the approved videos. We ask for your patience and understanding during this process. Thank you!

The Gifts of Asti by Andre Norton

Original artwork from Project Gutenberg - public domain

The Project Gutenberg EBook of The Gifts of Asti, by Andre Alice Norton

* * * * *



She was the guardian of the worlds, but HER world was dead.

Even here, on the black terrace before the forgotten mountain retreat of
Asti, it was possible to smell the dank stench of burning Memphir, to
imagine that the dawn wind bore upward from the pillaged city the faint
tortured cries of those whom the barbarians of Klem hunted to their
prolonged death. Indeed it was time to leave–

Varta, last of the virgin Maidens of Asti, shivered. The scaled and
wattled creature who crouched beside her thigh turned his reptilian head
so that golden eyes met the aquamarine ones set slantingly at a faintly
provocative angle in her smooth ivory face.

“We go–?”

She nodded in answer to that unvoiced question Lur had sent into her
brain, and turned toward the dark cavern which was the mouth of Asti’s
last dwelling place. Once, more than a thousand years before when the
walls of Memphir were young, Asti had lived among men below. But in the
richness and softness which was trading Memphir, empire of empires, Asti
found no place. So He and those who served Him had withdrawn to this
mountain outcrop. And she, Varta, was the last, the very last to bow
knee at Asti’s shrine and raise her voice in the dawn hymn–for Lur, as
were all his race, was mute.

Even the loot of Memphir would not sate the shaggy headed warriors who
had stormed her gates this day. The stairway to Asti’s Temple was plain
enough to see and there would be those to essay the steep climb hoping
to find a treasure which did not exist. For Asti was an austere God,
delighting in plain walls and bare altars. His last priest had lain in
the grave niches these three years, there would be none to hold that
gate against intruders.

Turn your Raspberry Pi into a HiFi music system

HiFi vintage stereo
For the past 10 years, I've worked remotely most of the time, but when I go into the office, I sit in a room full of fellow introverts who are easily disturbed by ambient noise and talking. We discovered that listening to music can suppress office noise, make voices less distracting, and provide a pleasant working environment with enjoyable music.

The Art of Whaling: Illustrations from the Logbooks of Nantucket Whaleships

PVC by Larry Heyl and Rootless Voicings for Jazz Piano

Here's an example of how to use rootless voicings to comp on a circle of fifths change. I call the change "PVC". I wrote it for this video Cm9 F7 Fm7 Bb9-Bb7 Bbm9 Eb7 AbM7 Abm7-Db7 (the chords with a dash between them are 2 beats each) And hear's how the voicings are spelled. chord LH RH Cm9 -- 3-7-9 --- 5-9 F7 --- 7-3-5 --- 9-5 Fm7 -- 7-3-5 --- 9-5 Bb9 -- 3-7-9 --- 5-9 Bbm9 - 3-7-9 --- 5-9 Eb7 -- 7-3-5 --- 9-5 AbM9 - 3-7-9 --- 5-9 Abm9 - 3-7-9 --- 5-9 Db7 -- 7-3-5 --- 9-5 These are known as Hearle voicings. Dan Hearle lays these and many others out in his book, "Jazz Piano Voicing Skills". Notice how the voicings alternate as you progress around the circle of fifths. This is called smooth voice leading and efficient motion. This technique avoids large hand jumps while playing. If you played all of these chords in root position your hand would be traveling about a half octave every time you moved to a new root in the circle of fifths. Voicing the chords this way you get many common tones and only one or two notes varying by a whole step or half step. Hence, smooth voice leading and efficient motion. One other thing to note is the use of parallel minor chords following dominant or major chords. This also helps the voice leading. Going from F7 to Bb9 is fine with two notes moving and one common tone in the left hand, Eb A C to D Ab C. Adding the parallel minor in between means there is only one voice moving with each change, Eb A C to Eb Ab C to D Ab C. Of course, the most important thing about any jazz comping technique is the sound. Rootless voicings are harder to learn and easier to play. The reason so many jazz pianists use them is because they sound great. Also on Youtube.

Learn awk by coding a "guess the number" game

question mark in chalk
When you learn a new programming language, it's good to focus on the things most programming languages have in common:
  • Variables – places where information is stored
  • Expressions – ways to calculate things
  • Statements – the means by which state changes are expressed in a program
These concepts are the basis of most programming languages.
