I am continuously impressed by Export Control lists. Apparently now we can't have free lunch in space with our computers.

Het blijft fascinerend hoezeer de kiezers loyaal zijn ondanks de puinhoop die de partij gecreΓ«erd heeft.

Risky Business Media News and commentary for cybersecurity and intelligence professionals

Regarding the ffmpeg drama, as discussed by @patrick.risky.biz on risky.biz: we should also consider that ffmpeg is/has been used by Google in Chrome and Youtube. Even if it's not directly, so many video makers are using that library, that Google really should bear some cost of development there.

Een artikel is sowieso beschermd als intellectueel eigendom.
Daarnaast heb je als reviewer afspraken met de conferentie/journal over geheimhouding. Dus misschien niet strafbaar maar wel problematisch.

Je mag ook niet het hele artikel als zoekopdracht gebruiken. Kernwoorden voor jezelf om dingen te begrijpen, ja. Een of twee letterlijke zinnen om plagiaat te checken, ja. Maar een heel artikel in Google gooien is niet okay. Want je geeft het daarmee weg.

When the Dutch have to take a detour on their bike, their world turns upside down.

That is a really long winded video, that mentions the same settings I already have turned off. With the exception of reminders for starting a workout. But I don’t want to turn those off, just the audio notification part. But voice feedback is already off.

How do I disable announced notifications from workout on my watch? These notifications are interrupting music or podcasts when I’m cycling and I don’t want them.

Since iOS 18.2 i have problems with Mail. It’s hardly downloading new mail from my imap server.

Anybody else having this too? Anything I can do about it to fix?

Nothing changed on my server end (Dovecot). I’ve even tried to disable IMAP IDLE, but that also does not help.

A dataset with exact locations of taxis that was not anonymised correctly, and led to the discovery of where famous people lived and how often they went to the gym.

AP: centrale database taxi’s te groot privacyrisico Het kabinet wil een centrale database taxi's. De privacy van passagiers moet beter beschermd worden, zegt de AP.

In many of my ethics lectures I use the example of the New York taxi dataset.
Imagine my surprise that the Dutch government now wants to introduce such a system.

The security implications of storing passwords insecurely are just mind-boggling.
Just look at how many leaked passwords we have already. And that’s with very actionable advice on how to do password hashing for years.

20.11.2024 08:09 πŸ‘ 1 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

There have been many studies on password behavior and even on leaked passwords to see how real life passwords were not getting any better.
The β€œwe need more data” argument is a well trodden path for scientists, but in this case, just don’t.

Password policies are evil and should be burned to the ground.

The piece that Stuart Schechter wrote on their history however, is so incredibly misguided.

It is bonkers to think that we would have had a more secure world without password hashing.

The way we do #science πŸ§ͺcurrently could do with some shakeups. This blog post by experimental history builds on some earlier posts, and lays bare the pain points of the current scientific climate. But it also presents a way to get out of that! Let’s build more #ScienceHouses !

It's a fascinating story, where the owner has come under the influence of a cyber charlatan/Mata Hari like figure.

Heh, we've just had an example in The Netherlands where an owner of a very large IT company was pushed by his board. They used a special legal procedure to show that he was incompetent. All of his shares in the company are now outside of his control.

Also, I have yet to see a case of an actual full disclosure, i.e. a public release of a discovered bug *before* it is fixed in OpenBSD.
