🗃️ Backups: Wipe fearlessly.
Have full #backups stored #securely before joining any protest. Depending on your threat model, cloud sync might be better than nothing — but understand you're #doxxing to #BigTech. Instead, try to create encrypted *local* backups. @eff ssd.eff.org/module/what-should

ssd.eff.orgWhat Should I Know About Encryption?Perhaps you've heard the word “encryption” used, but in so many different contexts it’s gotten confusing. You might have seen it referring to everything from protecting your laptop, chat app security, or guarding your shopping online. Regardless of when it’s used, when we talk about encryption, we’re referring to the...

Dear friends of #enhancement,
My #Sainsburys #online shop now works from the fediverse. And so it bleeding well should. [#apologies for the swearing] #Securely working and without their hosted out 'service' and data scraping marketing-sharing, 'loyalty card' #mind poison. ​:ablobcatpopcorn:​ Now of course they still share my #data with their marketing #outsource [sound of spitting] BUT that is the best I can #manage at the mo. Have food prices gone through the #insulated roof? You bet your shirt. BUT I am as #frugal as a mouse on #price-watch.

#Please #eat #well. #Grow if you can. Not width. Look after yourself and family if #possible.

Also cook a Tory. Plenty of fat on most of those #skimmers. ​:ablobcatcoffee:​

Why It's Impossible to Buy and Sell #Physical Goods #Securely via #Blockchain

Basically the final proof that Blockchain is not as secure as some people think, because in the real-world everything can be traced.

Paper
arxiv.org/abs/2110.09857

arxiv.orgIrrationality, Extortion, or Trusted Third-parties: Why it is Impossible to Buy and Sell Physical Goods Securely on the BlockchainSuppose that Alice plans to buy a physical good from Bob over a programmable Blockchain. Alice does not trust Bob, so she is not willing to pay before the good is delivered off-chain. Similarly, Bob does not trust Alice, so he is not willing to deliver the good before getting paid on-chain. Moreover, they are not inclined to use the services of a trusted third-party. Traditionally, such scenarios are handled by game-theoretic escrow smart contracts, such as BitHalo. In this work, we first show that the common method for this problem suffers from a major flaw which can be exploited by Bob in order to extort Alice. We also show that, unlike the case of auctions, this flaw cannot be addressed by a commitment-scheme-based approach. We then provide a much more general result: assuming that the two sides are rational actors and the smart contract language is Turing-complete, there is no escrow smart contract that can facilitate this exchange without either relying on third parties or enabling at least one side to extort the other.

is a small which erases files.

wipe writes over a file many times. On magnetic media this removes any sort of residual charge the media may have where the file was stored, hiding any trace of the file from the disk.

wipe can easily overwrite entire directories, changing the permissions of files if needed and requested.
