“I’ve had threats since Ali G and in my experience publicising them only does one thing: lead to more threats. We are in a very violent time. If you’re protesting against racism, you’re going to upset some racists.”

Wer in die Atacama-Wüste schaut, marktwirtschaftlich rechnet und sich die Strukturen mal unemotional anschaut, weiß dass weder Elektromobilität noch andere Verbrennungsmotoren wie H2-Verbrenner nicht die Zukunft sind. Die eignen sich gut, um das veraltete (Geschäfts)Modell des ubiquitären Individualverkehrs leisten können. Aber das hat leider keine Zukunft mehr, spätestens wenn man da auch das Verursacherprinzip anwendet. Marktwirtschaft halt, ganz sauber und eiskalt kalkuliert, volkswirtschaftlich.
Uberspace is one of the lesser known free hosters around. With the claim “Hosting on Steroids” they offer free-of-charge hosting for everybody – for a month. They have extremely extensive documentation in their wiki, but Owncloud oCIS wasn’t documented there. And since tools like that require some configuration specific to uberspace, here’s a little howto get it started.
Go to the “Ubernauten” website and register. The first month is for free, the 5 Euro product is enough for testing and running your first oCIS setup. I enter my e-mail-address, my favorite subdomain name (ocis for this blogpost) and confirmed. That’s it, ready to go. Please note the fqdn name of the server the Ubernauten give you, in my case it is hamal.uberspace.de.
You can now try to login via SSH, but that will fail because you haven’t set a password or a SSH-Key.:
ssh ocis@hamal.uberspace.de
The authenticity of host ‘hamal.uberspace.de (95.143.172.250)’ can’t be established.
ED25519 key fingerprint is SHA256:LGidXSzKaOcgBJWPtGEd049A5CDXIUIeqTz3IU/tU2I.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added ‘hamal.uberspace.de,95.143.172.250’ (ED25519) to the list of known hosts.
Password:
Password and SSH Key can be entered here (also linked from your datasheet). As you can see in the screen shot, OpenID is also an option. For security, you should use either SSH-Key or Open ID, not the password option. Upload your key, and login again:
# ~/.ssh> ssh ocis@hamal.uberspace.de

[ocis@hamal ~]$
Now it’s time to download ocis (via curl) from the ownCloud download mirror:
[ocis@hamal ~]$ curl https://download.owncloud.com/ocis/ocis/stable/2.0.0/ocis-2.0.0-linux-amd64
–output ocis
(…)
[ocis@hamal ~]$ chmod +x ocis
[ocis@hamal ~]$
Okay, time to start oCIS with ./ocis server, says Owncloud’s manual. But not on Uberspace – where we find some “special” conditions:
NginX to the rescue! Uberspace provides a proxy server that may reroute incoming requests to your local port 9200 – which is where oCIS is listening. So unless we have configured this proxy, the blank Ubernauten default html screen will be visible on ocis.uber.space. Thank God it’s all well documented in the Uberspace Manual, so here’s the steps needed for that:
uberspace web backend set / –http –port 9200
… which configures nginX to forward all requests to port 9200 of the local machine. The command
uberspace web backend list
/ http:9200 => NOT OK, no service
lets you check the success of the command before. Since there’s no local service running to answer, it’s NOT OK, but configuring the port 9200 to be redirected to our little ubenauten server has worked. Before we set up oCIS, we need some environment variables to be set aka exported:
[ocis@hamal ~]$ export OCIS_URL=https://ocis.uber.space
[ocis@hamal ~]$ export PROXY_TLS=false
[ocis@hamal ~]$ export PROXY_HTTP_ADDR=0.0.0.0:9200
[ocis@hamal ~]$ export PROXY_LOG_LEVEL=debug
[ocis@hamal ~]$ export THUMBNAILS_WEBDAVSOURCEBASE_URL=http://localhost:9200/remote.php/webdav/
[ocis@hamal ~]$ ./ocis server
With these lines you have told oCIS to listen to the desired URL, communicate through HTTP with the proxy and which adress to listen on. We set the log level to debug, be sure to unset that once your system is up and running. The last export is a variable that the current oCIS version needed in order to display previews for image files correctly (thumbnails). The command in the last line finally starts oCIS, you will see the following login window:
If you want to login, use the default users as mentioned on the owncloud documentation: Usage
Login to ownCloud Web
Open https://localhost:9200 and login using one of the demo accounts:
einstein:relativity
marie:radioactivity
richard:superfluidity
There are admin demo accounts:
moss:vista
admin:admin
As a test, you can now drag and drop files into oCIS. That’s it.
During the next days, I will try to get this article into the official Uberspace documentation on github, but that is hard, because it takes quite some time to follow their requirements, and there’s a lengthy style guide for contributors that does not make sense to learn for one-time-committers. It’s fine though for internal work of an editorial team, I guess.
Microsoft repo secretly installed on all Raspberry Pi’s Linux OS – nixCraft
“In a recent update, the Raspberry Pi OS installed a Microsoft apt repository on all machines running Raspberry Pi OS without the person’s or admin’s knowledge. Every time a Raspbian device is updated by having this repo, it will ping a Microsoft server. Microsoft telemetry has a bad reputation in the Linux community. Let us see why and how this matters to Linux users.”

Since early 2020 I’ve been telling my friends that I doubt there is a back to pre-corona thing. And I told them this is a stress test for societies, health systems, but also for the variety of authoritarian systems or non-authoritarism. I didn’t foresee that China and some Asia countries can party again while the free western world is locked in, but who would?
Has a year of living with Covid-19 rewired our brains? | World news | The Guardian
“People talk about the return to normality, and I don’t think that is going to happen,” says Frank Snowden, a historian of pandemics at Yale, and the author of Epidemics and Society: From the Black Death to the Present. Snowden has spent 40 years studying pandemics. Then last spring, just as his phone was going crazy with people wanting to know if history could shed light on Covid-19, his life’s work landed in his lap. He caught the coronavirus. Snowden believes that Covid-19 was not a random event. All pandemics “afflict societies through the specific vulnerabilities people have created by their relationships with the environment, other species, and each other,” he says. Each pandemic has its own properties, and this one – a bit like the bubonic plague – affects mental health. Snowden sees a second pandemic coming “in the train of the Covid-19 first pandemic … [a] psychological pandemic”.
“Loss of smell can be life-changing; it removes an important part of your sense of self,” says Chrissi Kelly, founder of the UK-based charity AbScent, which supports people who have lost the ability to smell. “Smell signals give depth to our social interactions. Erase all that, and your experience of the world is two-dimensional.”

“Wenn wir nicht rasch gegensteuern, werden wir schon sehr bald wesentlich öfter Pandemien erleben, die sich noch schneller ausbreiten als Covid-19, noch tödlicher verlaufen und die globale Wirtschaft in noch tiefere Krisen stürzen, als wir sie jetzt erleben.”
A study in California has laid bare the staggering scale of pollution from plastic microfibers in synthetic clothing – one of the most widespread, yet largely invisible, forms of plastic waste.
In under an hour and a half, The Perfect Weapon blisters through the proliferation of cyberwarfare in the last decade-plus: how offensive ransomware and disinformation campaigns have morphed from a undercover sideshow – as late as 2007, cyberwarfare was not even listed as a pressing concern on the US military’s threat assessment – into a relatively cheap, accessible and potentially devastating staple of international relations.

Deep learning to translate between programming languages
We’ve developed and open sourced TransCoder , an entirely self-supervised neural transcompiler system that can make code migration far easier and more efficient. Our method is the first AI system able to translate code from one programming language to another without requiring parallel data for training. We’ve demonstrated that TransCoder can successfully translate functions between C++, Java, and Python 3. TransCoder outperforms open source and commercial rule-based translation programs. In our evaluations, the model correctly translates more than 90 percent of Java functions to C++, 74.8 percent of C++ functions to Java, and 68.7 percent of functions from Java to Python. In comparison, a commercially available tool translates only 61.0 percent of functions correctly from C++ to Java, and an open source translator is accurate for only 38.3 percent of Java functions translated into C++.
