It has a fixed maximum number of concurrent sockets, and each socket has queues backed by per-socket fixed-size transmit and receive buffers (see `rxmem` and `txmem` in `struct tsocket`[1]). This is fine, because in TCP, each side advertises remaining buffer space via the window size header field [2] (possibly with its meaning modified by the window scale option during the initial handshake - see [3] & `struct PACKED tcp_opt_ws`), and possibly also how much it can maximally receive in one packet (via the MSS option on the initial handshake [4]; possibly modified by intermediary systems via MSS clamping). wolfip has unusually small buffer sizes, and hardcodes them via #define, and everything else (e.g. congestion control) is pretty rudimentary too, but otherwise it's pretty much the same as in a "normal" implementation.

It's similar to FedRAMP systems like AWS GovCloud (US), which can only be accessed by someone who is a US person (US citizen or lawful permanent resident) and on US soil (physically in the US at the time of access).

LACK tables specifically are well proven to be quite sturdy actually. They happen to be just the right width for servers / network devices, and so people have used them for that purpose for ages. Search for "LACK rack", or see e.g. https://wiki.eth0.nl/index.php/LackRack. 20kg is nothing; I've personally put >100kg on top.

Go to https://ui.perfetto.dev/. On the left sidebar, under "Example traces", click "Open Android example".

For a simple example using your own data, save this as a file and open it via "Open trace file":

  [
    {"name": "Example 1", "ph": "X", "ts": 1, "dur": 1, "pid": 0, "tid": 0},
    {"name": "Example 2", "ph": "X", "ts": 3, "dur": 2, "pid": 0, "tid": 0},
    {"name": "Example 3", "ph": "X", "ts": 2, "dur": 1, "pid": 0, "tid": 1},
    {"name": "Example 4", "ph": "X", "ts": 4, "dur": 2, "pid": 0, "tid": 1}
  ]

Or:

* Until they start rattling (https://techcrunch.com/2020/10/30/airpods-pro-rattling-crack...)

* An automatic update you can't roll back makes noise cancellation worse (https://www.theverge.com/2020/1/17/21069953/apple-airpods-pr...)

* They don't pair, or only one of them pairs, or they don't pair with each other (I personally have these three cases all the time)

Apples marketing department just works.

Nothing inspires fighting spirit like layoffs.
