Love learning stuff; both HW & SW! Mainframe owner. he/him. On a twitter break.

I'll stop using Twitter for an unknown amount of time (indefinitely?). You can find me on Matrix as @bluecmd:https://t.co/WQPiqAQi97.

The original low code platform

@jeremy_soller I usually just turn off password authentication in sshd_config. Stops these things and doesn't require fail2ban etc.

@sakjur Interesting, but it didn't have any vocals - it was only blippblopp like Bossfight or something.

Longest of shots: when I started using Linux back in 2002-ish I once used a distro that as I recall came with a music album (electronic genre, almost 8bit-ish) or at least some tracks. I thought it was either Mandrake or KNOPPIX which I used heavily, but can't find references.

[Christian Svensson @blueCmd]

I know that I reached out to the author of said album to give thanks, which I recall he appreciated, but it was on my Gmail that I haven't accessed in 10 years so I can't access that conversation. Anyone in the Twitterverse recall something like this?

The sudo dependency is really only needed because I don't want to make a setuid binary. If I did, I would make a binary that drops the PID argument and just changes the cgroup of the PPID - then anyone could change their current process's default VRF without dealing with sudo.

Fun little thing I wrote to make the default Debian bash shell VRF-aware. https://t.co/gkaKVsKH0S. I am using it to make my SONiC shells better, and support shell spawning straight in the management VRF instead of the default one. #SONIC_and_SAI

@linuxfoundation What is the goal of https://t.co/lxEsZrnWHi ? It seems to mostly hammer in stereotypes. I mean, what does changing a tire or enjoying crossword puzzles have to do with anything?

[rombik_su @rombik_su]

Remember @janmarjanovic 's discovery about second, hidden PCIe HIP in the Microsoft Stratix V GS (https://t.co/QwRxFwGYsX)?

Well, guess what, @gatecatte figured out how to enable it!

If you are interested in "fun" networking quirks, @blueCmd just wrote a blog post about a pretty interesting one discovered while trying to test a network topology with VLANs. https://t.co/6aziKOcyO0

Did we all just stop caring about core dumps when we moved to Kubernetes? I still want them, but Kubernetes seems to almost be engineered to make it impossible to collect.

Samsung S10 phone running a Soviet clone of IBM operating system #VM/SP r4 and calculating the N-Queens problem in #REXX. Because what else would I do at the #beach in the dog days of summer??

[Christian Svensson @blueCmd]

@andrew_randall @flatcar_linux @weaveworks Thanks! That works for my K8s stuff, but I need something for my other stuff as well (random database clusters, hypervisors, etc...). Can write something custom using semaphores and Prometheus alerting but prefer to join forces with existing stuff if possible :-).

[Christian Svensson @blueCmd]

CoreOS had coordinated reboots, did that survive into a healthy standalone project? Are there other reboot coordination projects worth considering? Asking for a CVE-2021-33909 affected *ahem* friend.

[Christian Svensson @blueCmd]

@lorenc_dan @julienBisconti @0xjosh @I_S_R_G @ProssimoISRG Very cool! It does not seem to be accepted yet, or am I missing where? https://t.co/3UkO3t4z5t does not list the commit nor the rust/ directory.

[Christian Svensson @blueCmd]

@zekjur @deliberatecoder And a USB stick I guess? I second the power thing, I have had really strange issues with RPi4 that have gone away by using a higher quality/powered power supply.

[Carl Bildt @CBildt]

Det förblir märkligt - om jag uttrycker mig mycket försiktigt - att Sverige fortfarande inte har en fungerande cyberskyddsmymdighet. Behovet har varit tydligt sedan år tillbaka.

[Christian Svensson @blueCmd]

@9600 Still, getting close!
