Implemented my own specialized memory allocator 26+ yrs ago. (Y2K timeframe) Probably older than the most of the CMU students :-(

Use pre-allocated pools with array of indexes, free/allocation idx for alloc and free.

Con: Fixed pool size and fixed amount of memory can be allocated per pool.

Pro: constant cost operations per alloc/free via Atomic inc/dec of idx - no linklist tranversing ; Can be alloc in kernel space and free in user space (linux/QNX) and in multiple user processes when memory pools are in shmem; Run very will in SMP environment without any locks - all memory contentions were handled with atomic +/- alloc/free idx.

Same source code run in QNX, vxworks and linux (kernel and user space) at that time.

As Dr. Ian Malcolm said it: “Your scientists were so preoccupied with whether they could, they didn’t stop to think if they should.”

About right, did it two years ago with 2 Sockets, 128Cores (64 core per socket), 256 Threads 2 Epyc Motherboard with 1TB DDR4. Build Kernel < 90 seconds. Should be faster nowadays....

Another idea for them: Walkatron for NFTs token for "....." causes....

RPi+ Yolo can do real time object recognition of cluster Tank, Trucks, BMP from orbit.

A service with real time streams of those objects + GPS data info directly from starlink for a select sets locations should worth a lot for DOD, NATO, Ukraine. DOD and NATO would likely flip the bill for everything need to build such system.

Love to see a container environment that can monitor Monitor and log all outgoing network connection requests.... Monitor and log all critical file/directory access such as /etc/*

With such container, we can catch the compromised supply-chain attach easily, right?

Does anyone know such container exist?

There should be some post post-processing algorithms that can remove/clean hex elements, right?

Got Honda Clarity PHEV since 2018. Loving it so far. It is 48 miles E range. I need ~36 for round trip daily commute. Charging at work is free. I remember only fuel up only 3 times in 2019 with the 7 gallon gas tank. Normal fuel up is 5-6 gallon only as it has a very small tank. But the Hybrid range is supposed to be 350 miles.

I also just installed solar at home. I expect the next family car would also be PHEV suv to replace the 16 years old minivan. Other than long trip, I don't expect to use gas much, maybe just once a week to oil up the engine for a few minutes.

Fog of war.

I have written time series logging db with sqlite believe that approach has following advantages:

   System performance scales well with latest SSD HW.
      As compare to cloud base approach that is limited by network/cloud speed.

   One can store logs per day / week / year in separate db files as needed.  

   Backup of small db files for last few days/weeks are trivial with rsync.

Love to hear other pro/con arguments from folks who use Timescale type approach.

One can easily cut the zip-tie, search and re-zip it again, right?
