What to do with an old iPad

news.ycombinator.com Unknown 2025-10-04 21:14:16

I recently inherited my parents’ old iPad 2. It had iOS 9 on it and was barely usable, in part due to how slow it was but mostly because of old SSL certificates and apps stopping support. But I wanted to give it some life because I hate to see a working machine go to waste. So I asked around and got a great answer: The iPad 2 can be downgraded to iOS 6.1.3 or 8.4.1. Both offer better performance than iOS 9 and have untethered jailbreaks. Once downgraded and jailbroken you can sideload hours and

Hurricane category 6 could be introduced under new storm severity scale

news.ycombinator.com Sascha Pare 2025-10-17 11:53:39

Hurricane Florence made landfall in South Carolina in September 2018. It was a Category 1 hurricane, but the devastating flooding that followed killed 55 people. A new hurricane categorization system could help people better prepare for storms by incorporating risks from storm surges and rainfall into the categories, a study published this month reveals. Storm surges — elevated seawater levels near coasts — and rainfall cause almost 80% of hurricane deaths, yet they are not accounted for in th

To set up an encrypted and authenticated pipe for sending email between two systems (in the author's case, from many systems around the internet to his central SMTP server, which then relays email to the rest of the world), one might run dd if=/dev/urandom bs=32 count=1 of=keyfile spiped -d -s '[0.0.0.0]:8025' -t '[127.0.0.1]:25' -k keyfile on a server and after copying keyfile to the local system, run spiped -e -s '[127.0.0.1]:25' -t $SERVERNAME:8025 -k keyfile at which point mail delivered

OpenSSH Post-Quantum Cryptography

news.ycombinator.com Unknown 2025-11-23 17:01:58

OpenSSH Post-Quantum Cryptography OpenSSH supports a number of cryptographic key agreement algorithms considered to be safe against attacks from quantum computers. We recommend that all SSH connections use these algorithms. OpenSSH has offered post-quantum key agreement (KexAlgorithms) by default since release 9.0 (2022), initially via the sntrup761x25519-sha512 algorithm. More recently, in OpenSSH 9.9, we have added a second post-quantum key agreement mlkem768x25519-sha256 and it was made the

Tailscale is basically a WireGuard orchestration service, with lots of nice features sprinkled on top. It’s a subscription product, b

Replacing tmux in my dev workflow

Hear me out, I can already read the descenting opinions: But I need session persistence! But I need split windows! But I need to group windows per project!
