If you ever wondered why most Matrix large group chats don't have E2E enabled - here's a good discussion of the problem and existing solutions https://blog.trailofbits.com/2019/08/06/better-encrypted-group-chat/ #cryptography
@gabek hi Gabe, no prob!
Attacks against #whatsapp protocol published on BlackHat 2019 https://research.checkpoint.com/black-hat-2019-whatsapp-protocol-decryption-for-chat-manipulation-and-more/
@nikolal scientists and engineers definitely not, but I periodically meet shopkeepers who make such comments when I order in kilograms :)
@nikolal yes, but the point is - is there any other legal definition of "1 inch" rather than "2.54 cm"?
Interesting fact: #uk #imperial units are all legally defined in #metric units. Inch is 2.54 cm, pound is 0.45359237 etc https://www.legislation.gov.uk/uksi/1995/1804/schedule/made

A big step for privacy in Arizona! The state ruled that "police & govt agencies cannot obtain [a persons' online data] without a search warrant, [which] requires a showing of some criminal activity," reports @azcapmedia.
As it should be in all regions. https://azcapitoltimes.com/news/2019/07/31/court-rules-arizona-residents-have-right-to-internet-privacy/

#BREAKING: Armed man driving "Trump" truck arrested outside migrant shelter in El Paso after immigration group spotted him "brandishing a knife." Police recovered a fully-loaded gun in his truck emblazoned with Donald Trump and Ted Cruz support slogans.
@kirschwipfel apparently you did not quite understand what the tool does
There's a nice #linux tool:
systemd-analyze security SERVICE
It looks at #security and confinement features used by systemd services as documented here https://www.freedesktop.org/software/systemd/man/systemd.exec.html
An example for my radvd.service
@devurandom точно :) также "skłoni cię zrozumieć" это копия "will make you understand"
A colleague found a nice archival document that documents similar #hacking activity from 1999 from #russia https://assets.documentcloud.org/documents/6007145/National-Security-Archive-Naval-Research.pdf

Oh, I finally found a way to easily bridge #ssb to regular web: a quick note about security features of new application packaging formats #appimage #flatpak #snapcraft #electron https://viewer.scuttlebot.io/%25%2FRS0FmBCprqW7Z6z7ExSqDfPVKOZb9Xh5wIPSlngHKY%3D.sha256
@farhan @Neui Here's more information about #datprotocol and other interesting newcomers https://blog.datproject.org/2019/03/22/three-protocols-and-a-future-of-the-decentralized-internet/
This is absolutely fascinating research: "450-million years ago a switch enabled plants to delay reproduction and displace new cells downwards from the shoot tips, paving the way to plant diversification" https://phys.org/news/2019-08-genes-enabled-scientists.html #evolution #biology #science
@Neui thanks a lot, fixing these now!
@Neui @farhan precisely, it's a really cool #p2p website protocol; check https://ssb.webcookies.pub (also my website)
