@kernellogger @linuxplumbersconf It would be nice to hear from possible candidates how they plan to address Rust, and how Linux community is going to address AI (not addressing is also one way to address it).

The Rust question could be further split into "what about GCC-Rust" and "what about defconfigs" parts.

Maybe LF could setup poll for candidates to answer these concerns? That could also spin more interest on voting.

This is why women cover their drinks when #elonmusk enters the room.

This was pretty cool:

❯ sudo bpftrace -e 'k:tpm_transmit { @start[tid] = nsecs; } kr:tpm_transmit { @[kstack, ustack, comm] = sum(nsecs - @start[tid]); delete(@start[tid]); } END { clear(@start); }'

Gives me total ns time for each possible stack while bpftrace was running :-) Nothing spectacular but I believe this might be enough to get hold of a performance regression:

https://lore.kernel.org/linux-integrity/D43JXBFOOB2O.3U6ZQ7DASR1ZW@kernel.org/

I’m a total beginner with eBPF stuff, and not an expert in tracing and profiling, so any improvement suggestions are welcome.

@ljs I find your comms inclusive as ****, I like when people are who they are ;-)

One question that I hate in English speaking countries (especially in States) is this "How are you doing?" bullshit. I'm like "I don't how I'm doing, what kind of fucking question is that. From which time range I need to report my ups and downs?" That question still totally freezes me every single time 😄 I've even practiced appropriate "protocol handshake" answers before departing Finland a few times in order to survive from the situation.

@kernellogger @linuxplumbersconf If Dan is available, definitely going to vote him. He is right type of personality for this type of position in my opinion, as far as my judgement goes.

Is there anything you would like to ask the #Linux Foundation's TAB (Technical Advisory Board)?

Then come to the "ask us anything" session with the current TAB at the @linuxplumbersconf 2024, which is currently scheduled for 9:00 on Friday, September 20[1].

And if you can't be there, just tell me your questions: I'll try to bring a few of them forward if I get a chance.

@ljs and non taken ;-) all cool

@ljs lol, i am what i am :D

@ljs lol

@vbabka oops lol right :--D In LinkedIn I was only contacted by weird recruitment consultants offering weird jobs, in here recruitment opportunities can happen sort of organically and naturally without image building nonsense :-) people see what you do, you see what they do, you like the same shit and that's about it.

@vbabka further apparently 7z l -r lists recursively. I wonder if you can get just the list without all the formatting crap and banner….

I needed to check if files went to a generated image and by accident noticed that 7z is actually quite nice ad-hoc tool for checking such thing:

BTW, the only "professional network" I used while looking for a new position was #Mastodon. There could not be a better environment to find new and interesting opportunities.

If I could decide, I would block all services from the EU region, which require smart phone to bind into them. That is the only real need for smart phone in my life and I'd really like to switch to a basic phone.

In my block list would be at least BookBeat, Signal, WhasApp and Telegram. We should just ban them until they fix the situation :-) I'm sure SMS based binding is doable.

I just hate smartphones so much...

@ljs @lkundrak @davesh @ibboard imho Apples power adapter with the international sockets pack is the best 😉 i use it with all my laptops in travel. Livin’ socket agnostic is great!

@orva Yeah, I mean these days if I install an app, I found out that it is actually a software development platform with a plugin system ;-) This applies to surprisingly wide category apps.

*Document Scanner

After scanning ~40 pages of contract documents I just want to say that #GNOME Document Scanner rocks! No bullshit workflow, gets to job done. This is rare 👍

oops, went of the hook with this: https://lore.kernel.org/all/D400W37FR01S.CLFIKA98YWX7@kernel.org/

I think it would be pretty interesting idea to use BPF like this in kernel.

If #decentralized #services become a thing, I wonder if #mainframe 's make a strong comeback 🙂 They are machines made for transaction throughput.
