Odd: if I send a TCP "MSS=600"-option to a Linux virtual machine, the option is ignored (by the system (with apache)) unless I disable tcp offloading!

It looks like my #aiagents file finally got into #qemu. Hopefully it will have some effect: https://gitlab.com/qemu-project/qemu/-/commit/3ab8a15569afa9ffd89971dff34d0636d48cae3c

I will attend the ESA Industry Space Days next week. I would be happy to meet and discuss our #RTEMS, #Linux, #NuttX, communication, #canbus, #SpaceWire, IP cores related work. Some examples

for RTEMS CAN/CAN FD, there is near to merge Ti AM335x suport, result of this year Ning Zhang #GSoC
motion control at #PiKRON (used by ESA for #satellite tracking and for LISA ground experiment), and at #CVUT (SaMoCon)
for rapid prototyping CTU Simulink™ support for Linux and NuttX which can be easily extended for RTEMS and open-source pysimCoder which already target Linux, NuttX and RTEMS (ongoing preparation for Ahmad Hisham’ s thesis)
the CTU CAN FD IP core is already available on mass produced MCU COTS silicon in addition to multiple FPGA applications including space ones
RTEMS LwIP port started as our experiment during Premysl Houdek’s thesis and #GSoC is getting traction and was used at docking computer during Artems II mission (by the way, there will be presentation about the mission at #cvutfel by Milan Halousek at Sptember 24) and is used on TMS570 and ESP32C3 RTEMS ports
our SumInt ADC conversion principle used in our HPLC instruments and tested at #nanoXplore for ESA which can have interesting potential for space silicon
our NuttX support for IEEE 802.3cg 10BASE−T1S Open Alliance SPI MACPHY can be ported to RTEMS etc.
I offer support for CAN/CAN FD emulation on #QEMU, #FlexCAN added this year
lot of our other real-time work for Linux, NuttX and RTEMS, se my university Open Technologies Research Education and Exchange Services topics and theses lists
we invest lot into #RISCV education at CTU, see our https://comparch.edu.cvut.cz/ pages with #QtRvSim emulator and our HDL education and sometimes even practically used cores and experiments

I arrive to Noordwijk around the lunch time on Tuesday September 15 and stay there to about 2 PM on Friday so there is lot of options to meet.

What would be the equivalent of Scheduler KIST (a C-tor option at one time) in #Rust #Arti #tor? Certainly not an option in the future paradigm. A man pages for the Cargo modules at (crates.io)? We can see "low water" in Arti which is exactly the cure. But it appears that a priesthood of operators will be in control of the fine tuning the torrc once had.

- Tor network adversary obstructs and degrades service with traffic shaping techniques.
"active bandwidth perturbations"
https://arxiv.org/pdf/2605.05887

- Threat Actor blocks tor from VMs
but TAILS not obstructed (virtuio pci, module xen uevent -- abstractions from hardware) -- pvh destroyed in Xen (libxl)

Proxmox 8. Настраиваем проброс видеокарты (GPU Passthrough). Выбор материнской платы на AM5 сокете

Уже прошел год как вышел Debian 12 Bookworm и, основанный на нем, Proxmox 8 . Несмотря на тот факт, что мои предыдущие статьи по пробросу дискретной Видеокарты в виртуальную машину , в кол-ве 4-х на Хабре, частично все еще актуальны для последней версии Proxmox , в тематических чатах регулярно поступали обращения обновить статью, а так же выяснилось что, у тех кто пользуется такими инструкциями, есть определенное непонимание в нюансах, из-за чего приходится проходить вместе с ними всю цепочку действий заново.
