Can passkeys replace passwords

“Passkeys and the WebAuthn specification were intended to make public key cryptography accessible to average users, rather than just the domain of the tech-savvy. If done right, they could seriously improve security on the Web.” @Drbruced summarises why passkeys are such a good idea in theory and explains where current implementations of the technology fall … Continue reading Can passkeys replace passwords

Was Griechenland wusste: das tödliche Geschäft des Abu Sultan

“Eine monatelange Untersuchung unter der Leitung des griechischen Investigativmediums Solomon und des Netzwerks Arab Reporters for Investigative Journalism in Zusammenarbeit mit El País und der taz ergab, dass die griechischen Behörden schon früh wussten, dass die ‘Pylos 9’ unschuldig waren, sie aber fast ein ganzes Jahr in Untersuchungshaft behielten.” Griechenland kriminalisiert systematisch die Opfer eines … Continue reading Was Griechenland wusste: das tödliche Geschäft des Abu Sultan

Viele gute Gründe für das Fediverse

“Die vor uns stehenden Umwälzungen der digitalen Transformation sind von historischer Dimension. Sie sind in ihrer Bedeutung vergleichbar mit den Veränderungen im Zeitalter der Aufklärung, die die Grundlage für die Menschenrechte und ein friedlich vereintes Europa legten.” Mario Birkholz sieht die Hochschulen in der Pflicht, ihre digitale Kommunikation mit den Anfoderungen des demokratischen Gemeinwesens in … Continue reading Viele gute Gründe für das Fediverse

Letter from Birmingham jail

"Moreover, I am cognizant of the interrelatedness of all communities and states. I cannot sit idly by in Atlanta and not be concerned about what happens in Birmingham. Injustice anywhere is a threat to justice everywhere. We are caught in an inescapable network of mutuality, tied in a single garment of destiny. Whatever affects one directly, affects all indirectly."

Descartes was wrong: ‘a person is a person through other persons’

“Nothing simply is itself, outside the matrix of relationships in which it appears. Instead, being is an act or event that must happen in the space between the self and the world.” Abeba Birhane does not simply regard human beings as either self-contained or self-sufficient. But can relational and autonomous accounts of the self be … Continue reading Descartes was wrong: ‘a person is a person through other persons’

European Comission gives EU-US data transfers third round at CJEU

"This third attempt to pass largely the same unlawful decision also raises questions as to the larger role of the European Commission being the guardian of the EU treaties. Instead of upholding the 'rule of law' the Commission simply passes an invalid decision over and over again, despite clear rulings by the CJEU."

What the Prisoner’s Dilemma reveals about life, the universe, and everything

"Okay, so now you've got this alternating thing, which will remind you of some of the politics of the world today, where we have to do something to you because of what you did to us."

Nichts zu verbergen? Ein moderner Mythos und 12 Argumente dagegen

"Aber der Satz und seine Verbreitung schaden viel mehr der Gesellschaft und anderen Menschen, als jenen, die ihn aussprechen. Deshalb sind mir die sozial orientierten Antworten darauf am liebsten: Weil man Menschen damit stigmatisiert, sie unsolidarisch behandelt, ihre Diskriminierungserfahrungen negiert, und weil es Demokratie und Widerstand untergräbt."

What’s in a PR statement: LastPass breach explained

“LastPass likely could have prevented this if they were more concerned about keeping their users secure than about saving their face. Their statement is also full of omissions, half-truths and outright lies. As I know that not everyone can see through all of it, I thought that I would pick out a bunch of sentences from this statement and give some context that LastPass didn’t want to mention.”

Strikes!

"Recently, the government gave us the Public Order bill that, that [sic] even one Tory peer described as an afront to a civilised society. Crackdowns on peaceful protest is the purview of China and Iran, not British democracy. And yet these reactionary fuckwits tell us it's Scottish primary school teachers who are holding us hostage. The bastards who wrecked the economy, squandered our reputation on the international stage, sold off any and all of the country's assets for a quick buck are getting their mates in the media to tell you that it's bus drivers, bin men, teachers, nurses, postmen, passport control workers and rail workers who are throwing the country to the dogs. Don't believe them; they are lying to you!"

Boomerang

"The Boomerang is hitting Britain hard, especially right now. Empire wasn't just something that happened to the Colonies, it's something that happened to Britain. It created some of Britain's most well-loved institutions, from the NHS to its greatest talents. But it also created the unequal Britain we see today."

The Monarchy: Last Week Tonight with John Oliver

"Will this segment even air on Sky TV in Britain? I honestly don't know! Maybe, maybe not. But if they do cut it out for being disrespectful, they won't want to seriously think about why. Why they and everyone else are working so hard not to offend a family whose name was branded into people's skin and who sit atop a pile of stolen wealth, wearing crowns adorned with other countries treasures."

Das Fediverse: Social Media losgelöst von den Fesseln kommerzieller Interessen

"Soziale Medien werden von Plattformbetreibern dominiert, die das eigene Interesse in den Vordergrund rücken und jede Entscheidung daran messen, wie sich eine Profitmaximierung erzielen lässt. Hat man das einmal verinnerlicht, wirft sich einem unweigerlich die Frage auf, was an sozialen Medien eigentlich sozial ist. Sozial bedeutet anderen zu helfen, was auch bedeuten kann, die eigenen Interessen zurückzustellen. Also im Grunde genau das Gegenteil dessen, wie kommerziell ausgerichtete Plattformen wie Twitter, Facebook und Co. agieren."

We the people who are darker than blue

Billy Valentine and the Universal Truth

This is a Britain that has lost its Queen – and the luxury of denial about its past

“Our parents and grandparents were recruited to Britain for its benefit, the terms and conditions of which my generation are still trying to make sense. We know how it feels to lack cultural continuity. Others in Britain enjoyed it at our expense. If continuity is an abstract subject, the other trappings of royal symbolism are more concrete. There were pompous reflections last week with the idea expressed in the Economist’s obituary that the Queen 'came from good Hanoverian blood'. If that sounds like a white supremacist idea, that’s because it is.”

The big idea: why relationships are the key to existence

“Too often we foolishly measure success in terms of a single actor’s fortunes. This is both short-sighted and irrational. It misunderstands the true nature of reality, and is ultimately self-defeating.”

The warning signs are there for everyone else to see

"It happens subtly. It happens when we see the Governments making decisions based on self-preservation, based on cronyism, based on anything that will keep them in power, we see the concentration of power whilst avoiding any of the scrutiny or responsibility that comes with that power. It arrives under the guise of respectability and pride, that will then be refused to anyone who is deemed different. It arrives through the othering of people, the normalisation of human cruelty. Now I don't know how far down that road we are. Time will tell, but the things we do in the name of economic growth—the warning signs are there for everyone else to see, whether they admit it or not."

Geflüchtete aus der Ukraine und Syrien: Unterschiedlich willkommen in Deutschland?

"Auch dieses Foto ist ein aktuelles Bild aus einem Krieg, den Putin gerade führt. Aber es wurde nicht in der Ukraine aufgenommen, sondern in Idlib in Syrien. Ein Krieg, den wir gerade zu vergessen scheinen, obwohl auch von dort zehntausende nach Deutschland geflohen sind aus Angst vor den Bomben Putins. Und, so groß die Hilfsbereitschaft für ukrainische Kriegsgeflohene gerade ist, so schwer macht es Deutschland den Geflüchteten aus Syrien, in diesem Land anzukommen. Die Menschenwürde ist unteilbar, sagt das Grundgesetz, und doch machen wir Unterschiede."

Western values? They enthroned the monster who is shelling Ukrainians today

“None of this is to defend Putin’s brutality. When 55 Ukrainian children are made refugees every minute and pregnant women in hospital are shelled mid-labour, there is nothing to defend. But to frame our condemnations as a binary clash of rival value systems is to absolve ourselves of our own alleged war crimes, committed as … Continue reading Western values?

Europe has rediscovered compassion for refugees – but only if they’re white

“There will be those who imagine that open arms for Ukrainians and fortress Europe for black and brown refugees can and should co-exist. They are wrong, and not only on an obvious moral level. Too many commentators in Europe have already fallen into the trap of separating deserving and undeserving refugees. Their rightful praise for … Continue reading Europe has rediscovered compassion for refugees – but only if they’re white

They are ‘civilised’ and ‘look like us’: the racist coverage of Ukraine

“What all these petty, superficial differences – from owning cars and clothes to having Netflix and Instagram accounts – add up to is not real human solidarity for an oppressed people. In fact, it’s the opposite. It’s tribalism. These comments point to a pernicious racism that permeates today’s war coverage and seeps into its fabric … Continue reading They are ‘civilised’ and ‘look like us’: the racist coverage of Ukraine

Sanction the oligarchs, not the people

“This is one of the main contradictions of our time. The confrontation between democracies and autocracies is overplayed, forgetting that Western countries share with Russia and China an unbridled hyper-capitalist ideology and a legal, fiscal and political system that is increasingly favourable to large fortunes. In Europe and the United States, everything is done to … Continue reading Sanction the oligarchs, not the people

COVID-19: endemic doesn’t mean harmless

“Thinking that endemicity is both mild and inevitable is more than wrong, it is dangerous: it sets humanity up for many more years of disease, including unpredictable waves of outbreaks.” Aris Katzourakis keeps the focus on how bad things could get if we were to give in to misplaced optimism. www.nature.com

Hammerhead Karoo 2 has landed

I pre-ordered the Hammerhead Karoo 2 during the last quarter of 2020, fully aware that I might be getting a device that would still require a significant amount of “continuous enhancements”. In other words, I bought into the promise of Hammerhead delivering “the world’s finest cycling computer” through software updates. Eventually. In many ways, the … Continue reading Hammerhead Karoo 2 has landed

They stormed the Capitol. Their apps tracked them.

“The location-tracking industry exists because those in power allow it to exist. Plenty of Americans remain oblivious to this collection through no fault of their own.

Nine lessons

“Too much of our political debate just insults people’s intelligence and just suggests that every facet of Brexit you don’t like is purely a feature of only the Prime Minister’s version of it, rather than intrinsic to leaving.” Sir Ivan Rogers advocates the need for serious substance to replace plausible bullshit. news.liverpool.ac.uk

Let’s be honest about what’s really driving Brexit: bigotry

“And those who promise that leaving the EU will deliver ‘control’ are really promising something quite specific: a social and cultural reboot.
