How to increase the Page Heap Size for Apache #NuttX RTOS ... So that NuttX Apps will have more Dynamic Memory for malloc()

@gemlog @lupyuen - There's room for more than one "right" answer to most problems. Just be sure to frame the problem.
Even yesterday's PC is unquestionably a better PC than any Pi-like substance. My always-on Pi (3) monitors smokeping, telemetry from several devices, PiHole, and several more tasks. The comparison of electricity consumed by a PC is laughable.
Turns out that "Pi" grew to encompass a few lines: education, hardware hacking, net appliance/server, workstation, etc. Not all are $35.

@gemlog @lupyuen That's the sad thing about Pi5: it misses the mark for ALL of those.
Too expensive for disposable hardware & education. (Pi Zero, Mango Pi, Ox64 hurt less to smoke. Each is < $10. All run something recognizably "Linux".)
Too wimpy for desktop/workstation use.
Not even price OR performance-competitive in its own market for net appliance, as Greeling calls out.
They released a 2020 product in 2023.

No trust, and icromanagement is probably the worst one; as that shows, you do not empower them to make decisions and take responsibility;
although time-wasting processes also, though easier to fix. the first is hard to deal with, as it is based on attitude of the manager.

@lupyuen A forth and probably morr impactful way that threat actors abuse Discord is by developing it.
"Threat Actors abuse #Discord in three ways: leveraging its content delivery network (CDN) to distribute Malware, modifying the Discord client to steal passwords, and abusing Discord webhooks to steal data"
"when it comes to specs and benchmarks, Orange Pi 5 Plus and Rock 5 Model B both clearly have the upper hand ... Raspberry Pi (5) clearly traded performance for cost"

I call BS on that one. Remote work, harsher economy and better weather is much more likely to cause air travel to drop than a few hundred people being shamed into stopping the travel.
"The number of people pledging to Stop Flying grew so much that Swedish air travel declined 5 percent between 2018 and 2019"
