What got me interested in blockchains? It was food delivery services. I disgrace Finnish food delivery service Wolt and how they ”Cosa Nostra” restaurants and enslave the drivers. I hope they burn in hell. So i realized year ago that only known algorithm to take away the middleman is a blockchain. Not by burning cycles and destroying the planet but by having distributed book keeper based on stake. I compared the existing smart contracts and with my evaluation Polkadot has the right core arch.

Tampere Airport. Off to Berlin.

So I did off-by-one with the week with my flights. I'm flying today Berlin and coming back next Friday to Finland. So week #1 on-site.

That means also that I get my contracts ready one week faster, and I can get back in sync with LKML one week faster too.

So... let's adapt to the situation :-) Now have to run to the airport.

Hmm... A gym at Berlin in the Kreuzberg area? I neither Zumba or anything physical jerks activity. Just weights and like one-time fee style [and there is a person to pay this too, you never know what to expect these days]

It's not an issue if there is some group exercise type of stuff but sometimes that will map having to queue and loosing motivation or the gear feels like shit. So with that condition that will work too.

hello thinkpad x1, never come back macbook pro :-) what i was thinking when i started at the university.

No luck with sending a letter to #Germany but going to #Berlin to deliver my letter containing ~30 A4's of various contract papers.

I'll spend there almost a week from 29th to 4th. I thought that it's good to not cut with traveling the very first week. I.e. that is the week when I trash my laptop and week 2 is the week fix it up :-)

Now off to the UPS Access Point (this was the corporate UPS, not the wet consumer UPS).

I don't mind going to Berlin so I guess "Finnish honesty" and 'German accuracy" delivered.

All my fixes in progress or landing them to rc2 might be postponed to rc3. There was one keyring (by someone from Huawei) and one TPM (by me). I don't care to check them now as I need to do Fedora reinstall.

For next week I cannot commit much promises, as it is my first work week and I need to also fly to Berlin for quick visit. I might check over next weekend, or then I just get drunk or eat döner. Perhaps I multitask dunno yet.

Eventually all will be addresses and landed v6.12. WIth a single rc delay. I might also send one patch that makes boot-time tracing just a bit more robust for CI style testing (with RFC task).

PS. If you want to blame someone, send your complaints to the Finnish Post Office, German Post Office and UPS ;-)

I checked corp DHL offer for 6 times per year delivery. It's way beyond I want to pay. My expectation ATM is one delivery total and it costs ways more than flying to Berlin and back.

I think that we can safely say that consumer versions of parcel delivery services have a single application when sending: a return package. For anything: don't do it.

Priority letter with tracking code failed for the first time ever (in the EU region) but there goes the trust, and I burned 30 EUR for nothing. It is tuition cost, don't mind but also the very last letter that I'm going to sen through post office.

Not much of a choice. I just fly to Berlin. It's 3x priority letter, guaranteed delivery, cheap quality beer and Döner. I can accept this outcome ;-)

I might fly to Berlin next week because post office lost my wet ink contract.

There was 2x successful delivery in the priority mail that originally sent, which can only happen, if you have found ways bend the space time continuum in a way not known to the current laws of physics.

See for yourself:

Successfully delivered. Twice. I know Berlin is weird but I did not know that it is quantum weird 🍄 And this was with priority letter that cost almost 30 EUR. Yeah.

I neither have much trust to courier companies, unless you are multi-billion corporate customer (like Intel, Google and similar size company). E.g. corporate DHL is totally different story than consumer DHL.

I went to UPS Access Point yesterday, and the dealer said literally that you should reconsider because your contract might get wet (it was raining). I asked WTF are you talking about. "Boys sometimes might forget them outside for a while so they might get wet."

"UPS - We wet your mail"

This is literally true - according to UPS. How I ended up to this awful sitcom 🤷 I'm a Mike Judge fan (Beavis and Butt-Head, Silicon Valley, Tales from the Tour Bus etc.) but do not want live inside his script for God's sake.

So yeah. Better to just pay for plane tickets, say hi to some friends and hand over the wet ink (*not* wet contract) by myself. I might be weird not crack smoking and glue sniffing weird like these delivery services 🤖

It's less than 200 EUR to get Berlin and back. I like the place, and I do like also Döner so better to start looking for tickets :-) Optimal would late next week but have to check also with people I need to meet etc. :-)

Not even pissed. Post and courier services fucking up consumers is a universal standard. Keeping your letters wet... Just had to write this down because this is beyond mental 🙂

Is there any non-Apple laptop of which 3,5mm connector does not suck? For playing not producing... And usually you have a sound card, controller or something but having such port is just a great backup.

I have no laptop ATM and planning to get a gig laptop and for that doing some configuration would pay off, given that it is then super stable and random "push notification" etc. crap does not appear randomly.

Just random note (and I think I stick to my mac for the time being e.g. because RME soundcards are proprietary as hell unfortunately).

One could make these quite easily a wine focused distribution for audio with wineasio for wiring into pipewire.

I.e. not Bitwig or other (available for) Linux DAW and yabridge but full-on everything inside wine. E.g. FL Studio performs better wine and is more stable than in Windows. For audio, wine is better Windows than current Windows. Even things like iLok (ugh) work these days without glitches (you need gnutls 32-bit for this, I found it by accident).

It has many other benefits:

1. One can snapshot the production environment because Windows is just a folder. This is useful for e.g. testing new plugins and making perfect clean ups after.
2. One can have multiple environments.

Making this an app ("manager' alike or something, this what Linux Steam is really) or a spin of distribution would be interesting idea. Pipewire was from get go a game changer in audio, it is actually just as a stack better than CoreAudio, but now that it has stabilized it is diamond.

Also, all RT just went to mainline, not sure if there is something that could improve from plain PREEMPT. And the biggest performance glitch was WaitForMultipleObjects (Win32 API), which was recently (either 6.10 or 6.11) recently fixed by having a driver and device just for this call, which bypasses nasty wineserver completely.

Personally I stick mac in audio (because I have RME BabyFace Pro FS) but Wine (with WineASIO) would actually be my option number 2, not because it is a "Linux way" but more like it has better user experience than Windows.

Just writing this down so that won't be forgotten :-)

Ooo, it's Mike Blumenkrantz's new post "My Wayland Your Wayland Our Wayland" https://www.supergoodcode.com/My-Wayland-Your-Wayland-Our-Wayland/ ✨

I want but does Telegram support SMS only binding? I can scrape Signal if it comes down to that ;-) Rad as hell.

Does anyone use dm-verity for anything? Looks almost like abaddonware.

This makes #Julia rad. You have like Jupyter notebook in a terminal! And with not much configuration (just add Plots and SixelTerm packages to the environment).

I don't care about learning a new language but it's all this other stuff in the environment that makes it so much more effective that it is worth it (and the language seems to be as trivial as Python anyway).

Game changer... ... ... in math ;-)

Deep Dive into RCU Race Condition: Analysis of TCP-AO UAF (CVE-2024–27394)

V4bel published an analysis of a race condition vulnerability in the TCP-AO subsystem caused by incorrect usage of the kernel RCU mechanism.

The researcher managed to trigger it reliably using the ExpRace technique.

Time for Paul's quiz session! Have been waiting for a new RCU article only because I love those quizzes even tho I'm not always that great solving them ;-)

Also the book "Is Parallel Programming Hard, And, If So, What Can You Do About It?" is worth reading.
