    That's sort of how Linux kernel trace-events are implemented [1]. E.g. DECLARE_EVENT_CLASS(sched_wakeup_template, TP_PROTO(struct task_struct *p), TP_ARGS(__perf_task(p)), TP_STRUC…

    I wish they offered a paid version of the browser that would have ublock enabled.

    > meaning no local variables (still heavy usage of push/pop within a procedure, does this count as a local?) Isn't it (push/pop) how locals basically work?

    OK, understood. So what you meant was more like puts()'s attack surface is smaller than printf()'s. This is not how your message appeared to me - "printf() is vulnerable to injecti…

    Good point. I suppose that you are talking about overwriting terminating NUL, do I get it right? puts() is vulnurable in exactly same way.

    I see. So when for a char pointer one needs to do printf("%p\n", v); the Generic call must look like this displayln((const void *)v); is it really better?

    Could be. But wouldn't then displayln() require the same string placeholder? Be it "%s", or "{1}" or someting else.

    I think Hyundai/Kia had self driving systems in development for the past, what, 5 years? Kia debuted its DriveWise in 2016. So they don't start from scratch.

    I pretend that '-s' stands for "source", not "symbolic"; and source file follows -s(ource) option. IOW `ln -s A B' is `link source A to B'.

    From the article - "No other agent had served Moscow for so well or so long." That's very questionable. No one knows who the greatest spy was/is.

    Yeah. OOM-kill handling wants to be a silver bullet, sort of. For instance, Linux kernel provides a number of I/O schedulers or net schedulers, etc. to pick from, but OOM kill is "…

    Maybe. But I can count something like 6 or 7 buildings on that pic which look glassy to me. I'd say there are several glassy (which reflect sky and water) buildings there [1][2]. […

    I like glassy buildings. Can stare at them for minutes; the article makes little sense to me. E.g. Hong Kong Harbour skyline, which is quite "glassy". Many people travel to take a …

    Slightly off topic. Can't help it, but the motif for pain (introduced @ 9:37) sounds to me like, I don't know, Windows (?) error/warning sound. Is it just me?
