Bluetooth Audio Problems Kernel 5.1x [SOLVED]

(Disclaimer: Going to Kernel 5.2 that early may cause undesired behaviour. In my case, up to now only wireguard (VPN) doesn’t work anymore, everything else looks great. Your mileage may vary.)

Since about a week or so I suffered from problems that somehow made the round on all of my desktops. All five of them suddenly refused to connect to Bluetooth audio devices that had been working flawlessly for years. Non-audio devices like smartphones would connect instantly, but headphones and audio receivers would connect and instantly disconnect.

I went to the always helpful opensuse mailing list “factory”  and asked. Within some minutes I got the hint I had been looking for on Google and all the other Internets for days: “Check a different kernel”. 

So I added the opensuse kernel repo http://download.opensuse.org/repositories/Kernel:/stable/standard/, refreshed, installed kernel 5.2: 

zypper ar http://download.opensuse.org/repositories/Kernel:/stable/standard/ kernel
zypper ref
zypper in kernel-default-5.2.0-9.1.g80522d2

… and the reboot did the trick. So if you are stuck without Bluetooth Audio on your Linux Kernel 5.1 system, check out an older (who would do that?) or newer kernel. I chose the 5.2 because it was tagged as “stable” and it has been working fine here for a few hours. AFAIK Tumbleweed, this won’t change. 


Nein! Doch! Oooh! Office 365 verstößt gegen Europäischen Datenschutz!

Reality update: Datenschützer: Einsatz von Microsoft Office 365 an Schulen ist unzulässig | heise online … :

Microsoft Office 365 darf in der Standardkonfiguration an Schulen wegen Problemen für die Privatsphäre der Nutzer derzeit nicht verwendet werden. Zu diesem Schluss ist der hessische Datenschutzbeauftragter Michael Ronellenfitsch gekommen, weil personenbezogene Daten von Kindern und Lehrern in der Cloud gespeichert würden. Auch wenn die zugehörigen Server in Europa stünden, seien die Informationen “einem möglichen Zugriff US-amerikanischer Behörden ausgesetzt”.

California today: Decommissioned, uninsured and broken containments: Nuclear plants in Diablo Canyon and San Onofre

California Nightmare | Telepolis … :

Hätten sich die Beben von Ridgecrest 250 km weiter im Westen ereignet, schreibt Wasserman, wären zehn Millionen Menschen in Los Angeles möglicherweise von einer Strahlenwolke bedroht worden. Denn die beiden rissigen, versprödeten, nicht gewarteten, nicht versicherten und durch die Atomaufsicht nicht inspizierten Reaktoren von Diablo Canyon hätten ihnen kaum widerstehen können. Wasserman erinnert daran, dass Wartungsdefizite an Gas- und Elektrizitätsleitungen von PG&E bereits zu Bränden und Explosionen in Nordkalifornien geführt haben.

In Washington sieht man das anders. Trump ließ vier Sitze in der NRC mit Lobbyisten der Nuklearindustrie besetzen. Jetzt schlägt die Behörde vor, die Inspektionen von Atomanlagen generell zurückzufahren. Das laufe darauf hinaus, schreibt das Ukiah Daily Journal, dass sich Betreiber wie PG&E oder Edison selbst überwachen. Diese Deregulierung sei in Zeiten großer finanzieller Probleme der Nuklearunternehmen besonders gefährlich und fördere die Tendenz der Betreiber, Probleme gar nicht erst öffentlich werden zu lassen.

For all California Expats, here’s the direct link to a moveon.org petition:

 MoveOn Petitions – Gov. Newsom, Test Diablo Canyon Nuclear Plant for Safety … : 

We, the people of California, ask Governor Newsom and other state leaders to order the controversial Diablo Canyon nuclear plant tested for potential dangers involving seismic vulnerability, pressure vessel damage and nuclear waste leakage before the reactor is allowed to re-open after being shut down for refueling in February.

Oh, and in the meantime… :

The California coast is disappearing under the rising sea. Our choices are grim – Los Angeles Times … : 

This “sea level rise suppression,” as scientists call it, went largely undetected. Blinded from the consequences of a warming planet, Californians kept building right to the water’s edge. But lines in the sand are meant to shift. In the last 100 years, the sea rose less than 9 inches in California. By the end of this century, the surge could be greater than 9 feet. Wildfire and drought dominate the climate change debates in the state. Yet this less-talked-about reality has California cornered. The coastline is eroding with every tide and storm, but everything built before we knew better — Pacific Coast Highway, multimillion-dollar homes in Malibu, the rail line to San Diego — is fixed in place with nowhere to go.

… spot the problem(s)… 

Icelandic Modern Media Initiative ready to start!

IMMI finally at the cusp of implementation … :

The goal of the Icelandic Modern Media Initiative in 2010 was for Iceland to take leadership in adopting the best possible laws, at any time, in order to be ahead of the digital tidal wave of disinformation eroding trust towards democratic institutions and traditional media. To be the first digital safe heaven for all the forbidden facts, to act as an inspiration for others to follow suit.

During the nine years since it’s passing, Iceland has undergone serious political crises with only one government being able to sit full term. Four governments and five Prime Ministers later, we finally have a deadline for IMMI to be fully ratified. In the first months after taking office as Prime Minister of Iceland, Katrin Jakobsdottir, announced she was committed to have all the laws finalized and put forward as governmental bills in Parliament before 2019 ends. The International Modern Media Institute was established in 2011 in order to make sure that the laws based on the IMMI resolution would be finalized no matter what political parties would be in charge. Even if the laws are not all ratified, the IMMI’s unanimous adoption by Parliament put Iceland on the top of the list of Press Freedom by Reporters Without Borders in 2010. Iceland has been sliding down since, but we are hopeful that by greatly improving fundamental laws for press freedom we will move up again. Democracy rests on the foundations of freedom of speech, expression, information and strong independent media.

In 2016, we were happy to meet Birgitta in Person… Awesome vision. Here’s a german article about her and immi: 

Missing Link: Kontrollverlust der liberalen Demokratien – Panik ist angebracht | heise online … : 

“Die Parlamentarier haben am wenigsten Macht”, kritisiert sie. Die Verwaltung, die Ministerialbürokratie seien die Zentren der Macht und trieben die Maschinerie der Gesetzgebung an. Verantwortungsvollen Politikern bliebe regelmäßig zu wenig Zeit, die kurzfristig vorgelegten Entwürfe so zu prüfen, wie sie es ihren Wählerinnen schuldig seien. Das Ergebnis sind nach Ansicht von Jonsdottir nicht nur zu viele, sondern vor allem qualitativ schlechte Gesetze. Jonsdottirs Bilanz ist bitter: Parteien wären Teil einer Religion, die Gesetzgebung sei die neue Bibel. “Das System ist selbsterhaltend”, klagt sie. “Aber es löst nicht die wichtigen Probleme, die wir lösen müssen.”

Giraffes, Docker and Incompetent Design

 Docker protects a programming paradigm that we should get rid of | Smash Company … :

Some biologists refer to this as Incompetent Design. The problem is that nobody ever sat down to full redesign creatures so that they could live on land.

And then Docker came along to help fix some of the problems that eco-systems such as Python faced in this new world of fast changing servers. Certainly, Docker helped a lot with paths and managing environment variables. For this reason, the use of Python tends to lead to the use of Docker, and the use of Docker encourages the use of Kubernetes. And in the end you have the recurrent laryngeal nerve of the giraffe. You ended up with something enormously complex, that arose incrementally, by trying to keep alive some pre-existing system. But if you were to sit down and design something entirely new, knowing all that you know now, you could build something much cleaner and simpler than what Python/Docker/Kubernetes gives you.

In that sense, Docker allows you to take apps developed with a paradigm from the 1990s, and deploy it in 2018.

Lionesses safeguard their investments by mating with multiple males.

What a beautiful cover… Battle of the sexes: a multi-male mating strategy helps lionesses win the gender war of fitness | Behavioral Ecology | Oxford Academic … : 

“By mating with multiple males, lionesses safeguard their investments and outdo the males in the war of fitness.

Battle of the sexes: a multi-male mating strategy helps lionesses win the gender war of fitness”  

Given a land-tenure system where lionesses encounter many males capable of killing unfamiliar cubs, multi-male mating buffers cub infanticide and likely diversifies paternal lineages in litters. Consequently, infanticide was observed only when “new” males invaded a female group’s territory. An age-based mate choice was observed in lionesses: maiden breeders chose males having highest range overlaps, whereas experienced females selected peripheral males. The intergender spacing patterns and resultant sexual strategies of lions differ in Asia and Africa probably because of contrasting resource availability, highlighting behavioral plasticity within species inhabiting diverse eco-regions.”

First step into parallel universes are about to be taken…

Scientists are searching for a mirror universe. It could be sitting right in front of you. … :

She calls it an “oscillation” that would lead her to “mirror matter,” but the idea is fundamentally the same. In a series of experiments she plans to run at Oak Ridge this summer, Broussard will send a beam of subatomic particles down a 50-foot tunnel, past a powerful magnet and into an impenetrable wall. If the setup is just right — and if the universe cooperates — some of those particles will transform into mirror-image versions of themselves, allowing them to tunnel right through the wall. And if that happens, Broussard will have uncovered the first evidence of a mirror world right alongside our own.

Fingerprinting device-tracking methods on the rise

Fingerprinting’ to Track Us Online Is on the Rise. Here’s What to Do. – The New York Times … :

With enough information gathered, fingerprinting can be very reliable. In a study last year in France, researchers found that about one-third of digital fingerprints they collected were unique and therefore identifiable. In a 2017 study, researchers at Lehigh University and Washington University tested a fingerprinting method that identified 99 percent of users.

Mayak. A nice place.

Majak-Direktor: «Kommen Sie, wir zeigen Ihnen alles.» | angeli beobachtet … :

“Q: Wir haben hier einen Bericht der russischen Atomaufsichtsbehörde, in dem steht, dass gewisse Becken mit flüssigen radioaktiven Abfällen ohne Rechtsgrundlage betrieben werden.

Das regeln wir bis Ende Jahr, dann bekommen wir auch eine Lizenz dafür. Bis heute ist die Gesetzgebung so, dass es nicht nötig war. Das ist nicht die Schuld von Majak.

Q: Das heisst, die Gesetzgebung wird angepasst.

Früher gab es in der Gesetzgebung keine Möglichkeit, so etwas zu registrieren. Jetzt gibt es diese Möglichkeit, und dann tun wir das auch. Wie kann ein Industrieuntenehmen überhaupt ein Gewässer beherrschen? Können Sie einen Ozean beherrschen? Ich wiederhole es noch einmal: Ich lade Sie ein, sich alles anzuschauen. Sie müssen das nur beantragen. Dann können Sie sich auch die Wiederaufbereitungsanlage RT-1 ansehen und die Röhre suchen, durch die angeblich radioaktive Abfälle in die Tetscha gelangen.

(Yes I know, 2010 or so.)

That’s important, because the concerns and beliefs of that “novel alliance” are closely aligned with those of the Free Software community. The new-found interest in hitherto obscure aspects of the online world and its software are an opportunity for the Open Source world to increase awareness of what it does, and to garner support for its activities. The potential for spreading the word is huge: over five million people signed an EU petition against upload filters, and 200,000 took to the streets to protest. Where new digital rights initiatives are set up to harness the recent mobilization of “digital natives”, free software coders can help people understand that open source is a key part of the solution to the problems they seek to address.
