Installation of #Fedora 40 Server with Screenshots
We've released #PuTTY version 0.81. This is a SECURITY UPDATE, fixing a #vulnerability in ECDSA signing for #SSH.
If you've used a 521-bit ECDSA key (ecdsa-sha2-nistp521) with any previous version of PuTTY, consider it compromised! Generate a new key pair, and remove the old public key from authorized_keys files.
Other key types are not affected, even other sizes of ECDSA. In particular, Ed25519 is fine.
This vulnerability has id CVE-2024-31497. Full information is at https://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/vuln-p521-bias.html
In bash, writing ${var?} instead of just ${var} or $var means if var isn't defined then bash will throw an error and _not_ execute your command, instead of expanding it to "" and carrying on.
mv file1 file2 $subdir # oops, I overwrote file2
mv file1 file2 ${subdir?} # error message instead of disaster
My favourite use of this is for example commands in documentation, with placeholders for the user to fill in. Then it's OK if a user accidentally copy-pastes it _without_ filling them in!
Proud of my progress in #emacs. Following along with System Crafter's excellent intro series on Emacs from Scratch. 1. Found my config file and added a few basics (line numbers and theme). 2. Finally got MELPA packages working and installed org-bullets for #orgmode.
I'm a lifelong learner, and this combo of writing, coding, and thinking really scratches several itches for me. Trying not to let it convince me I'm actually being "productive", but it's a lot of fun when things work!
I have been gaming since 1992 and building PCs since 2003. I enjoy Linux, supporting FOSS projects and am a tinfoil hat connoisseur.
Many FOSS projects rely on donations. If you have money to spare but don't know which to donate to take a look at the above links on Ko-fi, Github, and Open Collective. Anything on there that I have sponsered or contributed to is something I have found to be worthy.
