Crazy Rich Asians
Sis rented the film two nights ago and we watched as a family. It was better than I expected. I was mostly concerned that the milestone of Asian representation in a large-scale Hollywood production was overshadowing all the other good points in the film. Everyone I’ve spoken to mostly has technical nitpicks with the film (e.g. Ah-ma‘s distinctly mainland-esque accent – is this really a problem though?) and the strange anti-spread of “diversity” in the Singapore depicted onscreen.
I for one enjoyed the film enormously. I appreciate no-frills romances, even when no gimmicks are involved. Dress up a story appropriately and you’ll win me over just like that.
I do nag myself a little about on what terms did I appreciate CRA? I was raised on a modest amount of Mahjong, so I understood full well the significance of the Mahjong parlor sequence and felt all the more moved for it. Would a non-Asian audience, less exposed to Mahjong, take it the same way? I wager most would walk away (justifiably) confused, only inferring from context what transpired.
Actually, I confess here to being an inadequate Mahjong player – I didn’t read Rachel’s hand quickly enough to positively affirm what she had done. But from the context I thought her point was clear.
This is all a distraction – the film makes sense to and resonates emotionally with me. I walked away with satisfaction that I had fully grasped the story being told.
Firefox cgroups annoyance
On occasion, Firefox will eat all my memory. This does some awful things to the system at large and takes a while to recover. Eventually I relegated it to its own memory hierarchy out of annoyance; my launcher aliases have all been prefixed with cgexec. Now, Firefox is only allowed to chew through 8 GB of memory (ha!).
Firefox presently uses several different processes to perform different purposes (or so I deduce from their names):
$ pstree -aTp 8346

This past week, something started leaking memory while I was browsing Google Maps. I noticed the system slowly dramatically before the OOM-killer kicked in and decided to kill the WebExtensions process.
The immediate aftermath is not visible: since none of your content rendering processes are killed, you might not even notice anything wrong. I have 3 addons of consequence: NoScript, HTTPS Everywhere, and Vimium. Vimium mostly ceased to work (visibly so) and would not work until I had opened and closed a few tabs here and there. (I don’t know the exact mapping from tab to content process to WebExtensions process – but things were messed up).
The more exciting fallout was when I opened a Bloomberg article and was suddenly treated to an irksome auto-playing ad. I smacked the Alt+M and opened the NoScript menu with annoyance. It drew a blank – that was when I noticed the toolbar icon was superimposed with a question mark, indicating a non-functional NoScript.
So far, no sequence of opening new / closing old tabs has recovered this. The next step is to restart Firefox to see if that fixes things. While I hesitate to prognosticate, it follows that any reliance on your addons for security must always be tempered with some understanding that the architecture is not perfect.
I hesitate to prognosticate – so I will refrain – but I believe this reproducible by
- Opening Firefox,
- Finding the content process with pstree (not sure why pgrep is showing a different cmdline),
- Killing it with your favorite signal (SIGKILL to simulate OOM-killer?), and
- Checking if NoScript dies.
